    Default Re: [HOW-TO] Simplified Root + Recovery + Custom ROM

    I'm getting right on that. Is there anything I can do by removing the microSD and copying stuff directly to it?

    edit: Also, is there any way to get more time? It goes through that system recovery thing in approximately a second.

    <snip> Followed directions, got it back to recovery, at least.

    So so now I'm booting into Xionia CWMA, at least. So do I now just format everything like you said and attempt another ROM? I feel like I was doing it wrong, because I couldn't get a single one of those ROMS to boot.

    update: I can boot into CWMA, and that's it. I wiped and formatted everything, and did a restore from a backup that was one of the ROMs I downloaded, and I'm back into a (LG logo->off->LG logo->off) loop. Tried "fix boot loop" function, still in loop.

    So I tried those ADB commands again, because someone else was saying it would fix a boot loop, and I got this:
    Code:
    root@YOURMOM:~# ./adb shell flash_eraseall /dev/mtd/mtd8
    Erasing 128 Kibyte @ 160000 -- 91 % complete.
    Is that 91% complete thing weird? Does that mean it only erased 91% of the file?

    Default Re: [HOW-TO] Simplified Root + Recovery + Custom ROM

    I was able to successfully flash Mirage ROM and reinstall most of my old apps and data using Titanium backup. Except for the time it took to reinstall 50 or so apps one by one, the rest of the experience was smooth. I recommend going through the generic guide for flashing roms . The references to the SMS backup/restore and the exact options to choose in the recovery console were useful. For a first time user, simply saying use recovery console is not enough. I was able to get Link2SD also working just fine.

    I wish there were more detailed instructions on what apps can be transferred from the stock ROM to the custom one. E.g., I didn't realize that the google talk is not available on the market and that it is included as part of the gapps. When I restored it using the Titanium backup, along with other apps, I realized that it is incompatible. Fortunately, I was simply able to flash gapps again. I wish there is an easier way to filter the list of apps such that I won't miss anything useful but not accidentally install any crap from the stock ROM. I am still not sure if I missed anything from the huge list of apps that Titanium backed up. I basically skipped anything that doesn't have a descriptive name, hoping they are all system level packages that already have equivalents. Out of the rest, I also skipped those that Titanium detected as having already installed. I hope this information is going to be useful for someone in the future.

    Update: Due to some specific sequence of restoring apps from Titanium and some possible bugs in Link2SD, some apps failed to link and that caused the dalvik-cache directory to fill up. Also one of the subsequent cleanups I did ended up removing apk files for some or all of these that were partially linked (again possible Link2SD bug) and that caused the loss of applications. With the help of some directory diffing and following broken links, I was able to find about 40 apps that were in this state and reinstall/restore them. Took a good couple of hours, but my troubles are not over yet

    I don't know how this one started, but Link2SD reports that the mount didn't happen in time, and so offers to do a quick reboot. However, quick reboot goes into some sort of a loop, possibly due to something crashing. I have tried to reboot 4 times so far, and I have the same sequence of events. I am now at a complete loss. Until I can figure this out, I will have to move back a few crucial apps to internal memory.

    Default Re: [HOW-TO] Simplified Root + Recovery + Custom ROM

    After using it for a day, I began seeing an issue with the cache partition. Actually, I noticed that some of the apps started disappearing from the app drawer, with their shortcuts on the desktop turning to stock icons and they can no longer be launched from there. If I go to the Market page for these app, they show up as if they are not yet installed. Trying to install them again, gets me an error that there is not sufficient space.

    Right before I started noticing this issue, I installed the new google talk client with the audio/video support, so in case the problem is somehow related, I went back into recovery to reflash gapps. When I was trying to clear caches, I noticed recovery giving me an error that says something like "Error in CACHE: recovery/log (No space left on device)". After a couple of attempts to clear caches, I went back into CyanogenMod and all apps showed up, and I was able to even start one of those apps, so I assumed the problem went away. But after a few minutes, they started disappearning again and the same error from Market when I try to reinstall them.

    Why is my cache partition getting full? I never created it manually, so I am assuming it has some standard size, so why is it not enough in my case? I would really appreciate any help with troubleshooting this issue. Thanks a lot in advance.

    I have my phone rooted and have been using the Cyanogenmod in this first post of this thread for a few weeks now with no problems.

    Simple question for you all: Is it all right to completely wipe my SD card so I can use it to flash my tablet? Or are there important files on there that would cause this ROM to malfunction if I were to wipe it and reinsert it later?

    Thanks for the help,

    you can wipe it and not worry about it.
    I'd back it up on your pc first in case you find you need something from it later, though.
    like the nandroid backup you were supposed to make before installing cyanogenmod.
    you can even run the phone without the card entirely, but it won't download anything without one.

    yes, that would do fine.
    hopefully you'll never need the backup anyway.
    I don't think it matters too much what you do to the card before you reinsert it...
    android (or cyanogenmod android) won't handle more than 4 card partitions, though. any more than that, it won't see 'em.

    Phone: Optimus V
    Provider: Virgin Mobile

    Apps installed:
    File Manager
    Gingerbreak APK 1.20 (1st Post link, XDA 3rd Download, Unmounted Mini sd and used sd adapter for laptop, Copied file to New folder "gingerbreak apk" Used File Manager and installed to phone.)

    USB Debug: On
    Outside Source Downloads: On

    I opened the gingerbreak apk and started "Root". An hour passed as I left phone and came back later.

    Exited app and rebooted phone as it was still on and the message on screen was as follows:

    Rooting ...
    Running exploit ...
    This may take a few minutes !
    Device will reboot on success !

    After Phone turned off and back on. I started it once more. It has now been another 15 min and still running with the same message.

    Anyone had this problem and know how to fix or what to change.

    Please Help I am running out of space, battery is draining (I think root helps reduce power or allows a root battery app to help with this.) I have a 2gb Card. I might update in the future but I feel even spending $10 to $20 on a 16gb card or smaller 8gb, or 4gb (32gb was $55 wtf ).

    This was the best step by step guide I found overall for rooting the optimus v and I don't know what to do from here since something is wrong or I have the wrong download. What do I do now?

    The gingerbreak may need multiple tries, give it about 10 minutes before pulling out battery & reboot. But it sounds like it worked since it rebooted by itself. To check if you have root, download "terminal emulator" app, and start it, type 'su', you should see a # prompt. If you do, then proceed with next step. Otherwise retry using gingerbreak.

    Edit****

    Scratch that. I uninstalled a few unneeded apps and made sure I plugged it in to the laptop as I didn't before. I let it work for 5 minutes and it rebooted by itself now.

    The next step on the list for Root was busybox. However now that isn't working. It won't install because it is saying I need to reflash the rom. Do I skip this and move on to part 2 or part 3?

    1. Is there a free version of flash image gui(said there was but server leads to market)?
    2. If no, Is there a similar program that is free?
    3. My dad bought 3 phones(Mom,Dad,Me) and I set them all up. If Flash Image Gui is the only app, is there a way to install on all 3 phones with 1 purchase of the app at the 99 cents.

    My debit card is F'd and I am having enough hassle just trying to get my dad used to as well as not hate the optimus v. His fingers don't like the screen, and battery usage for stand by is ridiculous. Standby uses more power than having it on all the time.

    Have your Dad use the voice recording to send messages, less typing that way.
    Also, for the battery to last longer, don't use FaceBook, etc, and use Airplane Mode as much as possible, like at night. It works for me, but even still, I only get a day out of it. I've gotten used to charging it every night.

    Wow, I can't believe how easy it has gotten to flash a good recovery, root and install a rom! I remember having to use psneuter and how unstable the cm7 roms used to be.

    Thanks for making this guide, it really made it a snap to root and rom my grandmothers new optimus v. She's very happy she can tether with her netbook now (she doesn't have broadband but an excellent sprint coverage area)

    Use the flash image GUI app in step 5, there's no need to type anything in terminal emulator.

    Windows Drivers for the Optimus V (Optional, but suggested):


    Rooting

    Rooting is the process of gaining administrative rights to the phone so one can do customizations that aren't normally allowed. Root by itself doesn't do anything interesting, unless there's an app that needs it. The fancy stuff comes from custom ROMs. Just remember Virgin Mobile Activation only works on Froyo ROMs, so do it before going to Gingerbread. The easiest way to root nowadays is to use GingerBreak. It can be found here:

    Can I use flashimage gui to flash a new rom instead of using clockworkmod ( I have iho recovery installed anyway)
    If so, do I need to also flash the gapps to get the android market?

    I am a learning newbie



    Instruction Steps:

    1. Turn on USB Debugging (Settings - Applications - Development)
    2. Copy the GingerBreak.apk to a /sdcard dir, then using a 'file manager' app (search for one in Android Market) install it like a regular app.
    3. It can take up to 10 minutes, and will reboot automatically when complete (rooted), if attempt fails, reboot manually & run it again.


    Install custom recovery image

    The recovery image is an alternative bootup instead of normal Android Operating System. It allows low-level operations such as backup/restore a ROM, wipe partitions, and flash ROMs.

    4. Download and copy the recovery image (works with new & old OV screens) onto your /sdcard.
    5. Install the (save the .apk to a /sdcard directory, then open it with file manager). Run the app & select 'Recovery Image' option with the file above.


    Flash Custom ROM

    [ROM+Kernel] Inferior Human Organs unofficial CM7.1 (Gingerbread)

    6. Copy the unextracted ROM .zip that you wish to install to the /sdcard dir. Also if installing a CyanogenMod Gingerbread ROM, the unextracted also needs to be placed in the same dir to flash right after the ROM .zip.
    7. Boot into Clockworkmod recovery mode (From powered off state, hold vol-down, home, and power button until the LG logo appears).
    8. FIRST, BACKUP ORIGINAL ROM! Don't continue until this is successful. use vol-up/down, camera, & back keys to navigate in recovery.
    9. Wipe Data/Factory Reset, wipe cache partition & dalvik-cache. Then under Advanced Settings, format all partitions EXCEPT /sdcard.
    10. Flash the custom ROM.zip from sdcard and gapps.zip too if going to a CyanogenMod ROM
    11. Reboot and enjoy the new ROM, the first boot takes longer than usual, also some problems may disappear after rebooting.

    NOTES:

    - NEVER use the Android Settings 'Factory Reset' from now on, only do factory reset & wipes from within recovery mode. Most ROMs should have this option removed from the Android settings.

    - Some newer Optimus V screens hardware changed, see link: [FIX]Black screen with custom recovery and custom roms (BobZHome's IHO recovery from the Wiki binary -> recovery page also works with newer screens.)

    - If restoring a backed up ROM in CWM recovery gives 'MD5 mismatch' error (likely caused by renaming a ROM backup). Try this fix:
    # cd /sdcard/clockworkmod/backup/<name_of_backup>
    # rm nandroid.md5
    # md5sum *img > nandroid.md5

    - If you ever want to restore to original stock ROM (ONLY on OV's with older screens), with original recovery and UNrooted:

    Thanks for the great walkthrough, this is my first flash/rom install, and it went well. However, I now realized I forgot to format all partitions (except /sd). Should I go back and do this, are just leave it? Everything is working, I only realized this well after I set up my phone with the IMO with the MIUI look. Thanks for the advice

    Nope, if everything's working fine then no need to format, that's just a precaution step.
