    Exclamation [FIX]Black screen with custom recovery and custom roms

    Ok, now I've walked /edit several edit/ different people through fixing this glitch, and now I'm starting a new thread about it so hopefully I can just point people here instead of doing a full walkthrough each time.

    In a nutshell, new and refurbished Optimus V phones are apparently starting to be shipped out with display hardware from the newer Optimus S, which shows a black screen with kernels built from LG Optimus V or older Optimus S source code.

    If, when booting your 'new' phone into a custom recovery, your phone only seems to boot to the silver LG logo and then goes black- but doesn't reboot- you may have this problem. If you already installed Xionia CWMA recovery, and it works, but your custom ROM boots into the black screen right after the silver LG logo, you probably are in the same boat.
    NEW EDIT:
    if your ROM is still working, and you're adb/terminal impaired, but you need to install a recovery, use this app:
    flash_image gui

    <edit> Now recent releases of IHO-based unofficial Cyanogen-Mod7 ROMs should have a kernel included which will work with either type of screen, so get one if you don't want to mess with flashing a compatible kernel (next paragraph) over a ROM.
    <redacted post of modified IHO recoveries, since BobZhome's works great, but it's still in downloads section if you want 'em anyway>
    Also, now LeslieAnn has updated Harmonia to 1.7, which contains a new version of the Picasticks OV kernel, which works fine on the newer OVs with no modification needed.
    New: Harmonious Bumblebee based on Harmonia, good for new and old phones as well.
    If you still get a black screen on boot after flashing a Harmonia variant, you can flash the picasticks remix zip listed below from recovery and that should fix it.

    Compatible kernels to flash over old ROMs to get your screen back
    NEW Picasticks v7 rebuild for new-screen OVs with Froyo-based ROMS (older Harmonia, Bumblebee, Stock)
    kernel thread
    Picasticks remix anykernel download (flash in recovery with signature verification OFF)
    <deprecated, good luck finding, old mediafire links are all broken.>Fear not! Uber-dev Zefie made a very nice kernel some months back with the display drivers you need included. 2.6.32.33 no less, most (older) kernels for the V are 2.6.32.9 instead. You can use his old Xionia kernel[/URL] (original post <here> be sure to get v13 or v14 AnyKernel version) or:
    Drew has built from Zefie's source again more recently with added tweaks: Xionia Redux.




    Recoveries you can see
    NEWEST! Reccomended for IHO roms. Recovery .img from an IHO builder (BobZhome) with IHO kernel. I've tested it personally and it worked well for me.
    The Xionia kernel is included by default in the Xionia CWMA recovery (post <here>, direct download link <here>) download flashable zip version here

    others:

    IHO recovery with kernel from new OV stock recovery
    iho-vm670-X-recovery-40143, flashable zip:
    iho recovery, .img file:
    xionia_kernel_clockwork-3024
    All of these hacked recoveries (except the new IHO recovery with the new stock OV kernel,) like the unhacked xionia cwma, have the home and menu keys reversed. The Clockwork recovery is an older version than current, so you don't use the camera key to select; use the home key instead of menu or camera to select. IHO recovery, use the camera key to select.

    Reboot loop (LG screen, recovery screen -> formatting -> rebooting)
    If you have a reboot loop going, you'll have to install Xionia recovery first to fix it, even if you want to use another recovery afterwards.

    You may also need flash_image if you used something like ROM manager (ugh, now I've gotten on the "I-hate-ROM-Manager" train) to end up with the black-screened recovery or ROM, instead of installing the custom recovery the "old-fashioned" way with ADB or Terminal Emulator.

    Using your black-screened custom recovery the 'easy' way (one guy did it)
    No walkthrough, just the general idea. Sorry. Never could get Android Screencast to work in Linux myself.
    Find Android Screencast on Google Code. Follow their instructions to install.
    Use it to navigate your recovery with your PC. Put one of these kernel-hacked recoveries on your SD card, and use the blacked-out recovery to install one you can see, then reboot the phone into the new recovery and proceed to install your ROM.

    Installing a recovery the old-fashioned way (maybe the only way, for your new screen, if you flashed a ROM and recovery at the same time with ROM manager) :
    To manually flash your shiny new custom recovery, put the recovery.img, flash_image, the Xionia a newer AnyKernel zip, the keyswap zip, and your chosen ROM all on the root (base directory) of your SD card. Open Terminal Emulator on the phone itself, if your rom is still working, and type the following code (if you're using adb, you can drop the first two lines and replace with "adb remount" (no quotes when you type it)):
    Code:
    su
    mount -o remount,rw /system /system
    cat /sdcard/flash_image > /system/bin/flash_image
    chmod 755 /system/bin/flash_image
    mount -o remount,ro /system /system
    flash_image recovery /sdcard/NAME-OF-RECOVERY.img
    if you get any errors above, don't type the next command or you'll boot into nothing...
    research the errors before trying to reboot.
    Code:
    reboot recovery
    NAME-OF-RECOVERY.img should be replaced by the filename of whichever of the recoveries (not the .zip versions) you have chosen to use.

    that sequence of commands will install, and reboot you into, the (hopefully) working recovery.

    Installing another ROM:
    (EXCEPT for EmuZombie's rom, other recent IHO-based ROMs, Harmonia 1.7 (or newer,) or Harmonious Bumblebee; see next section below this for info)
    Any time you install an older rom.zip (like plain Bumblebee) you MUST install either a:
    the Picasticks remix kernel, no keyswap needed, for Froyo ROMs
    or, Xionia AnyKernel and key swap zips, for Froyo or Gingerbread
    or, BobZhome's kernel v3 or newer, for Gingerbread ROMs (haven't gathered an anykernel of BobZ kernel yet, sorry)
    or you will get the black screen when your phone boots into the new ROM. You do not need to reinstall the kernel or keyswap for mod .zips, like statusbars or whatever, only right after you change or upgrade your ROM.
    format boot, cache, dalvik-cache, data, and system in recovery.
    install the rom.zip
    install the Anykernel.zip of your choice
    install the key swap.zip (if using a Xionia kernel)
    and reboot.

    Compatible ROMS:
    now BobZhome has fixed a kernel in the IHO repository, so builds from Sept. 1 should include a compatible kernel as well.
    IHO wiki binary release page for compatibility with new screens, no Xionia kernel needed
    Harmonia 1.7
    Harmonious Bumblebee


    <deprecated but still works>
    EmuZombie has cooked a pure IHO CM7 with Xionia kernel 'specially for this issue. Yay!
    His post is here
    With EmuZombie's IHO rom, you don't need to flash the custom kernel or keyswap. He built in Xionia 13 and a swapped thunderkeypad.kl file, so all you have to do is flash his ROM in recovery (the IHO dev reccomends the IHO clockwork variant recovery to avoid issues.)

    Default Re: [FIX]Black screen with custom recovery and custom roms

    Hello, I'm having massive problems with my optimus v. Got a replacement from VM, carried out a ROM recovery.. and the same problem as mentioned here. Screen goes black after the LG logo startup.

    I've copied all the files as mentioned on an SD card, I plug the card in the phone.. connect the phone via usb.. and I can ADB into the phone. So far so good. However, when I try the 'su' command I get a "not found" response. Another weird thing is that without the SD card when I do a adb shell I get the # sign.. and with the SD card inserted I get a $ sign. The phone was rooted prior to the recovery process.

    I'm going out of my mind.. I spent more than 5 hours yesterday trying to fix this Please help!

    Default Re: [FIX]Black screen with custom recovery and custom roms

    you got a custom recovery installed, right?
    try adb shell while booted into recovery. that should allow su.
    to boot into recovery, unplug the phone and power off by pulling the battery. put the battery back and press and hold home+volume up, then press and hold power as well until the silver lg fades to black.
    then wait about 10-20 seconds, plug in the phone to the pc, and try adb shell again. you'll have to add a line after su.
    Code:
    mount /dev/block/mmcblk0p1 /sdcard
    if that doesn't work, try pulling the sd card before booting into recovery.
    then put it in after booting to recovery, and try the adb commands again, including the added mount line.
    it sounds like su is missing from your rom.

    Thanks so much - after a lot of tries, it has finally booted into clockwork mod recovery (3.0.2.4) Oddly, su never worked - whether I had the sd card in or not.. I just went ahead with the mount line and then proceeded with the rest. Phew..

    Now, sorry to bother you again, what should i do? It gives me options - reboot system now, apply update from sdcard, wipe data/factory reset, wipe cache partition, install zip from sdcard, backup and restore, mounts and storage, advanced and power off? I'm assuming 'install zip from sdcard'?

    Oops, looked like I bricked the phone - even adb can't see the device.. phone is stuck at lg logo when booting normally.. when in recovery mode nothing. Oh well, sending it back to VM, thanks for your help, I'm not touching any hacks again lol!

    these don't totally brick too easily. soft-bricking is common. you can recover it with fastboot if you're motivated, but it sounds like the glitches have made you squeamish.
    if you can get into recovery there is a good chance you can fix it.
    removing the battery for a couple of minutes gives the phone a chance to settle its internals, and if you want to keep trying I might be able to help you through the process of reflashing.

    Would love to try, I just figured that if I can't access it at all, it was completely dead.

    I took the battery out for more than an hour, booted in recovery mode.. still can't access it via adb. The scenario is that I still have my older optimus v (the one I purchased when it first came out) The mic stopped working, so VM sent me this replacement.. unfortunately it had 2.2.3 on it, which meant the hotspot feature didn't work.. so I tried to copy the ROM from the old phone on to the new one, obviously I messed up somewhere.

    Default Re: [FIX]Black screen with custom recovery and custom roms

    if you can boot into recovery you won't need adb anymore.
    choose a rom and put it on the card (google apps too if you want a gingerbread rom, but Harmonia 1.5 or Bumblebee are safe bets too)
    in recovery, format boot, cache, dalvik-cache, data, and system.
    install zip, choose the rom.zip
    if you picked a gingerbread rom, install zip, choose google apps.zip
    install zip, choose the xionia anykernel.zip
    install zip, choose the keyswitch.zip
    reboot.
    I bet you're using windows if adb died. try opening device manager, show hidden devices, and uninstall all LG and Android drivers, reboot the pc, and reinstall the LG optimus drivers. that may fix your adb issue.
    and, I forgot to mention, custom recoveries default to su, you don't need to type it.

    could you be more specific? I'm guessing that was on the "flash_image recovery /sdcard/xionia_cwma_125186.img" line?
    did it have any other output before the error?
    /edit/ extra info, probably too late:
    that error -1 probably means wrong filename.

    the menu options you need:

    advanced
    wipe dalvik-cache
    yes

    press the back key to the main menu

    mounts and storage
    format system
    yes
    format data
    yes
    format cache
    yes


    that will format everything.
    press the back key to the main menu again.
    the rom and kernel you use install zip from sdcard. in that order, rom then kernel (unless you're using EmuZombie's IHO-Purity-X, then you just need to flash the rom and not the kernel or keyswap.

    copy these files to c:\android\platform-tools:

    flash_image
    xionia_kernel_clockwork-3.0.2.4.img
    VMU670-CM7.1-RC1-IHO-PURE-XIONIA-09042011.zip

    next, from what you said in the other thread
    Code:
    cd c:\android\platform-tools
    adb shell mount /dev/block/mmcblk0p1 /sdcard
    adb push flash_image /sdcard/
    adb push xionia_kernel_clockwork-3.0.2.4.img /sdcard/
    adb push VMU670-CM7.1-RC1-IHO-PURE-XIONIA-09042011.zip /sdcard/
    it'll take a little while to push the ROM, don't worry, it's just slow because it's a relatively big file. Be patient.
    when it finishes that:
    Code:
    adb shell
    mount -t yaffs2 /dev/block/mtdblock5 /system
    cat /sdcard/flash_image > /system/bin/flash_image
    chmod 755 /system/bin/flash_image
    ./system/bin/flash_image recovery /sdcard/xionia_kernel_clockwork-3.0.2.4.img
    exit
    adb reboot recovery
    that should get you into the modded Clockwork recovery. I <think> (I forget) Xionia recovery uses the older scripting or I'd say use that instead...
    Since the Xionia kernel has the home and menu keys backwards, you select with the home key.
    In recovery (and only ever in recovery) select wipe data/factory reset.
    select yes.
    press back button
    select advanced
    format dalvik-cache
    yes
    back button
    mounts and storage
    format cache
    yes
    back button
    select install zip from sdcard
    select the VMU670-CM7.1-RC1-IHO-PURE-XIONIA-09042011.zip
    select yes.
    select reboot.

    that should get you going again. This is the easiest way I can put it... thank EmuZombie for providing a ROM build to simplify this.

    hey bigsquid, thanks so much man, i was really gettin worried that i would go have to buy a new one, but i've made some great progress thanks to your work, really thanks a lot.

    everything worked good, and when i was in recovery i did everything you said and also installed the exact rom you specified. the only thing is though, when i hit reboot system, it went straight back to cwm recovery. i downloaded some of the kernels you had listed in this thread and tried flashing those, didn't make a difference.

    i've had an optimus v in the past, and im not sure why, but it seems like clockworkmod never seems to work too well with the v. when i had my other one a while ago, i had the same problem when i tried flashing cwm and every time i had tried to install a rom, they never worked. i ended up flashing another recovery called thundrc or something.

    i understand though that these new optimus v's have different drivers/screen and such and that causes problems with the existing software we have, so thats my dilemma. will i have to stick with this hacked version of cwm? and what else should i try to get a rom installed and working?

    thanks a lot man, your a lifesaver.

    ROM
    bigsuperROM_os2sd

    Default Re: [FIX]Black screen with custom recovery and custom roms

    install the Xionia CWMA recovery from the OP and it should break the reboot loop.

    since cwma is working you can mount usb storage in recovery and not need to push with adb.
    once it's on your card, in recovery go to
    mounts and storage > mount /sdcard
    then open an adb shell and
    Code:
    flash_image recovery /sdcard/xionia_cwma_125186.img
    I just don't remember whether it uses amend (old) or edify (current) scripting language for installing roms and flashable zips. I'll check this morning. /edit/ yes, it supports the newer scripting, so you can use it on newer roms and not just, um, deprecated roms that aren't actively supported anymore.
    if you want a specific recovery, like IHO or current ClockworkMod or thunderc let me know and I'll patch it and add to the OP to give people some choices. xionia cwma is the best next to clockwork I think.
    Recoveries have their own kernel and it's a PITA to change it. you can't just flash a kernel into a recovery (well, you can with fastboot, but you have to split the recovery.img first.)

    since you have Clockwork recovery on there you can flash this:
    xionia_cwma_125816 zip
    then go to advanced and reboot recovery.
    hopefully the signature works, if clockwork complains about it, turn off signature verification.

    under advanced in xionia recovery is a fix factory bootloop option.

    Default Re: [FIX]Black screen with custom recovery and custom roms

    alright man, i definitely think we're almost there. i flashed that recovery zip in clockworkmod, and then rebooted recovery and what happened was, it turned off, came back on, and then the new recovery loaded up but instead of displaying recovery options/etc, it automatically said:

    Android Recovery
    Do not pull out battery!

    ...formatting data
    ...formatting cache
    ...factory reset

    and then it loads up CM7. so i was like huh? phone booted up fine (thank god), and then i was curious why the recovery hadn't booted up and gone straight to the rom. so i rebooted into recovery and the same thing as above happens. and not only just when booting into recovery, every time you turn the phone on and off. yeah....lol.
    i appreciate all the help man.

    god damnitt, erghhh, i tried to fix it myself, so i tried using adb to install some different recoveries and then see if they would boot up without wiping my data every single time. and that wasn't really working

    so i tried flashing this recovery img (in adb):
    iho-vm670-X-recovery-4.0.1.4.3.img

    and then flashing this recovery zip in the iho recovery:
    Xionia_CWMA_12518.6_VM_Recovery-signed

    and then after that i also flashed this kernel:
    xionia_kernel_013_bootimg_OptimusV_signed

    Now what happens is, the phone boots up and does that thing where it says "android recovery, formatting system, cache, factory reset, etc" and it just shows the lg logo and its stuck on that. and every time i pull the battery and try to use the recovery key combo it just keeps saying the same thing and and getting stuck on the LG logo. ughhh, i should'a just waited for you to post back....

    oooo, that's a no-no, unless you're using a stock Froyo ROM.
    You need the AnyKernel version of Xionia, or your ROM won't boot (unless you're using a stock or mostly-stock ROM.)

    As far as your reboot problem:
    from mmarz, this thread...
    If you still have the boot loop or if you were already on Xionia and reinstalling it doesn't fix it, try these commands with adb:

    Code:
    adb shell strings /dev/mtd/mtd8
    adb shell flash_eraseall /dev/mtd/mtd8
    zefie mentioned back when he was devving for this phone that those commands should work.
    you have to 'spam' them in adb, paste 'em over and over as the phone is rebooting until they take, and it says done or ok or whatever it says other than device not present.

    I had my phone go into the same kind of bootloop way back, but at least I could see my screen

    after the bootloop is broken you can install whichever of those recoveries from the OP that you want.

    Hey, so I spammed those commands using adb on startup, and eventually it seemed to work. After that I used adb to flash the recovery xionia cwm, the recovery with the blue text. It worked! Then in that recovery, I reinstalled the cm7 rom and I also used the option fix boot loop and then restarted the phone. Booted up without any problems and no boot loop!

    I was never really a gingerbread fan, so I decided to go back to froyo and I flashed the rodimus rom. Immediately after I flashed the xionia any kernel, and rebooted. Everything went fine and still no boot loop!

    I assume every time I flash a new rom I'll have to flash the xionia any kernel? Just want to clarify. Thanks a lot though big squid, you really helped me out.

    yep.
    unless people start either building a kernel patched with the new video drivers specifically for the optimus v, or build a xionia kernel into a custom rom like emuzombie did. If so, I'm sure they'll label it so you know the kernel swap isn't necessary.
