Un-Brick method for SOME forms of brick

[JINXR65]

Well, it's bricked again. I noticed that the home button wasn't working, so I tried shutting it off and turning it back on. But it's stuck at the LG screen again. When I shut it off, I only had 17 percent battery remaining. I'm worried about running out of battery. Should I go through this process again?

Can you boot to recovery right now? If so while in recovery, wipe/factory reset <from recovery only!


Plug it in for a bit and let it charge before doing the process again if you cant boot into recovery.

Even if you can boot to recovery, I would charge that battery.

No, I couldn't get into recovery. I went through the process again. Didn't even use the battery until it was done. I went straight into recovery and wiped everything. Hopefully I won't have anymore issues. Looks like this method has saved my butt twice today.

 

[sfhub]

I'm happy you got it resolved, but it seems strange that your unit would brick on its own during normal operations when you aren't doing any flashing (or is that too much of an assumption?)

 

[JINXR65]

Nope, I hadn't done anything with it since going through the un-brick process.

I do think that I forgot to wipe everything when I flashed the VCRom007 onto it. Maybe that's what caused the reboot brick? I'm about to reboot it again. Keep your fingers crossed for me.

ETA: Rebooted just fine!

 

[JINXR65]

Bricked again. Tried using Z4Root after noticing I no longer had root access. It went through some of it's process before the program shut off. I tried opening it again and it immediately force closed. Checked root status with Root Checker. Still no root. Tried to reboot the phone and it's stuck at the LG screen again. Bricked.

Gonna try this un-brick method one more time and if it works, I'm not messing with my phone ANYMORE.

 

[sfhub]

I really think something else is going on with your phone. z4root shouldn't be bricking your phone. It is just running something like the rage exploit and moving some files around.

 

[JINXR65]

Update. When I tried getting into Emergency Mode, only the buttons lit up. The screen was blank but flashed on and off again a couple of times. Then the recovery menu popped up. ??? Weird, but whatever. So I wiped everything and I applied a nandroid backup that I saved before ever tried flashing the VCRom 007. So far, it seems to be working ok.

Sounds like he restored V9 then flashed VC with the V9 radio...

 

[JINXR65]

Sounds like he restored V9 then flashed VC with the V9 radio...

Here's what I did:

1) Updated to VC using the LG Update tool on my computer

2) Rooted using ADB

3) Installed Custom Recovery

4) Performed a Nandroid backup and installed VCRom 007. Forgot to wipe everything. Phone booted to the Nexus splash screen then rebooted itself and was bricked.

5) Used this method to un-brick it using the VC cab. Phone booted up, my stuff from before the VCRom 007 was still there. Home button didn't work so I tried turning it off and turning it back on to see if that would fix it. Phone was bricked again.

6) Used this method to un-brick it again using the VC cab. Immediately went into Custom Recovery and wiped everything. Phone booted up normally and I went through the initial setup procedure. Got all my apps downloaded and noticed I wasn't rooted anymore. So I tried using Z4Root rather than go through the long process again. Z4Root crashed. I tried turning my phone off and on, but it was bricked again. Couldn't even get into recovery.

7) Started to use this method again to un-brick it. As I was trying to get the phone into Emergency Mode, it booted up into Recovery instead. So I immediately restored my nandroid backup from step 4.

My phone is still not rooted and I doubt I'll even try rooting it again. I had a Hero running all kinds of custom roms before this phone and never had an issue.

seems to like to freeze up quite a bit and then i get stuck back at the silver lg logo hafta pull the battery numerous times and it will finally boot back into the phone.

 

[riggsandroid]

Having same issues as a few others, phone attempts to restart at end of flashing the .cab file and fails to reboot, stays stuck at LG Logo.

Are there any other .cab files available to flash through this Utility? Like for bootloader, recovery, etc?

 

[Ruff]

i managed to get back in to mine after doing this unbrick method only by removing the sdcard and pulling the battery and replacing it numerous times it eventually gets past silver LG boot logo and shows the sprint logo and then on in to the phone as it should, but if i replace the sdcard it makes the phone unresponsive and i have to pull the battery yet again

 

[sfhub]

Have you tried a different sdcard?

 

[Ruff]

yes, ive tried 2 different ones with the same results, so i formatted them both and tried again and havent had much of a problem with it yet, if i power the phone off and then back on i still get stuck at the LG logo for a little while but with persistence and alot of battery pulling it boots back into the phone.

 

[kazea182]

Earlier this week I downgraded to V8, went to V9, then to VC. Had NRom and GB working fine. Going between the two a couple times this week. I had found a fix to my main issue with GB (Rotary behind calls) so I formatted my SD Card, rebooted my phone, and I am stuck at the LG Splash. So everything was working, after this restart it fails to start up with or without the SD card. I attempted using this but when trying to go into E-Mode I do not get the "Emergency Mode' screen in red letters as I should. I am unsure what needs to be done...

EDIT:
I was able to get into E-Mode, but when updating it doesn't continue. This is the log from the updater.

PLEASE HELP!!!

 

[denshigomi]

Do you think this would work on an Optimus V? (I can get into custom recovery and adb, but I can't mount /system)
Would I need a different cab file, and if so, any ideas where I might find it?
Thanks!

Edit: Yes, it requires a different cab file that can be downloaded from LG. But as of this writing, the cab file for the Optimus V on LG's site does not work correctly for this flashing method.

Ok, I'm really stupid, but i decided to flash a ROM (CM7) without doing a factory reset (this was an accident) . I tried this unbrick method a bunch of times, because it worked the LAST time i was stuck at the LG logo indefinitely, to no avail. BUT... I did it once more, this time using the V9 cab, and it went through and my phone works again. So, if at first you don't succeed, try to use v9 and it might work. But more importantly, don't be stupid like like me, please wipe factory before flashing a rom.
