I try to start my optimus t and it wont get past the android logo. I rooted, installed titanium backup and deleted some of the stock apps. Now it wont get past the android logo. I've tried the hard reset. What do I do?
Have you tried removing battery replacing it again (mostly wont work) . Try recovery it will erase everything but there's a chance. If nothing works go to emergency mode and KDZ it!!!

Wipe it
Hi,
I know this problem. If you have flashed a custom recovery (search the board, it works like a charm) then you need to simply wipe the phone and restore the data later with titanium backup.
If you don't have a recovery you will need to flash this KDZ.
Greetings

I used kdz and I'm back to new. flashed megatron and it worked too but void got me stuck at lg screen so I'm back to stock now. Thanks for the help.

I've previously used LGMDP to install clockworkmod and haven't had any problems. I upgraded to V20g using LG's update utility and that's been fine, though it's T_Mobile branded. I've tried to install the unbranded European V20e through LGMDP and that's where the problems started.
At the end of the V20e flash, I got errors when it tried the NV restore. Items 1 to 158 have a status of NV_FAIL_S. After that, the phone won't boot. It gets stuck on the Android boot animation.
I've tried NV Restore with previous backups that I know have been OK before, but it still fails the same way.
If I use LGMDP to flash T-Mobile V20g, then flash clockworkmod (still getting NV errors), I can run clockwordmod & restore my backup from before I started this. After that, the phone boots & seems normal. I've got a signal, anyway.
I'm still a bit worried that something isn't right, though. It still refuses to restore the NV. I've tried going back to V10g using LGMDP and it fails to restore the NVs and the phone won't boot.
So, has clockworkmod restored everything I need and is there any way to fix this so I can use LGMDP again?
I think I've resolved this now, so I'll post what I've done in case anyone finds this in a search.
I already had a V20g KDZ file for my provider, which I got by following the instructions here. I looked for an alternative flash app and found details of KDZ Updater here.
V20g flashed successfully with that software. After that, I've tried LGMDP again and can do an NV Restore with no errors now, so things look like they're back to normal.
I still can't flash V20e with this software, though, I still get stuck on the Android boot animation.
I had changed baseband 3-4 times. In last 3 attempts, I also got these errors. But my phone rebooted normally after these errors. I had fully working phones in all the cases. Don't know why there were errors?
Same thing here. Hundred something NV_FAIL_S errors but phone seems ok though.
You have to do factory reset after flashing new ROMs.
This may solve bootloop.

ive never heard of this one before. isnt it just wipe cache, dalvik cache, etc, in recovery?
I decided to try again with V20e but used the kdz file and KDZ Updater this time. Same thing happened, stuck on Android boot animation.
So I put clockwork on, wiped cache & dalvik, tried again, same problem. Reboot into clockwork, factory reset, reboot, same problem. Finally, I booted into clockwork, went to Advanced and Fix Permissions. After that it booted fine.
While installing clockwork through LGMDP I didn't get any errors. I've also tried an NV Restore with no problems. No idea what went wrong the first time.
Ok so I'm fairly new to the rooting scene, and these forums, but so far everything has been pretty good, except for one small problem. I installed a custom boot logo, and afterwards my phone was lagging a bit. I contacted the boot logo programmer, with no response, so I decided to wipe my system and use the backup from right before I installed the custom boot logo. Unfortunately, the boot logo has not changed, and my phone 'fails' whenever I try to flash something from Odin. Anyone know what to do in this situation.
If you want to do a full wipe of you device,cos it sounds like tha boot logo is corrupt,then boot to recovery and wipe cache partition and dalvik cache.then go to "storage and mounts" and format system,data and cache.Select "Go Back" and factory reset your phone and reboot.If it doesnt go past the boot logo after 1min then pull the battery,put it back in and turn it back on.Its a pain in the arse but it will completely clean up your device and if you where rooted you will need to probably reroot but berfore hand plug in your phone to your PC so it gets recognized again.
EDIT:Just incase,first of all download titanium backup from the market and backup your apps!!!!

You need to wipe usb storage, sd card, then put phone in download mode, flash stock ROM using Odin. You need to fully wipe everything.

I've trying reflashing the stock ROM and kernel; however, it gives me a FAIL and says can't open the serial (COM) port.
I have solved the problem by closing Samsung Kies and wiping the system, thanks for all the help offered.
Hello all, could use some help here.
I'm trying to restore my Note to the factory ROM and I'm running into an issue.
Fyi, I had the latest Paranoid JB Rom from Oct 13.
I followed the proceedures outlined in the forums (used ODIN to restore the default "attstockrom") and after that restore the phone would loop rebooting into ATT rethink possible animation screen.
I found and downloaded the latest 4.04 rom for the phone (I717UCLF6) and rebooted. Now it just hangs at the "ATT Rethink possible" graphic (no animation, no loop).
Odin does see the device fine so I can reflash again with no problems if I need to. I'm thinking of trying the I717UCLA1 version from Jan to see if that works but I'm hoping I can get some better advice before I do something that might cause more permanent problems.
Any advice on how to get back to stock ICS (or even JB) and get the phone working again?
Thanks!
Try doing a factory data/cache wipe from Recovery.
I flashed the stock rom via ODIN. There is no factory data/cache wipe since there's no custom recovery.
Are you suggesting flashing CWM/TWRP on the phone now then doing that?
Houston we have liftoff. Thanks for the tip Fappa, that got me into the phone (reinstalled cwm, factory reset). However I'd still like to remove CWM and go back to completely stock....
I'm not overly worried about it as I'm selling the phone but I'd like the new owner to have a completely clean phone in case they need to send it in at some point for repair. But in any case it's up and running with CWM and factory ICS rom.

I'm sure fappa meant to use the stock android recovery and wipe. when I go back to stock it always hangs at AT&T boot logo and have to wipe/reset from stock recovery to get it to boot.

Yes do what they say or you will continue to boot loop.

Hello Buddy,
Just Factory Reset your device from CWM, it will solve your problem. If it doesn't work then reflash ROM...
before posting please completely read related thread carefully.
Hi!
I have a problem with my LG Optimus 3D (P920). Installed the JellycreamV3 and it went good, untill everything was complete and I restarted the phone as instructed. Now my phone stucks at startup logo. Its been like that for hours but nothing happends? I have tried to restarted it several times without any resaults. Please help me. Its my first attempt to install new android version.
Perhaps your install was bad, try reinstalling it, or maybe you didn't clear the cache, system, data?

- Boot into Recovery again
- Wipe data/cache and go to "Advanced" and wipe Dalvik (yes, this will delete everthing, but you don't exactly have a choice)
Reboot. If it's still hanging
- Boot into Recovery again
- Re-flash ROM
And BTW, didn't you make a backup of your original ROM? If not, well.. you won't go any places fast. Another tip is to go to the thread where you downloaded the ROM and ask for help there. People there have flashed the ROM, and some may have had the same issue as you have now.
I try to go into recover-mode but it just starts up and get stuck on the logo:S I did a backup but no matter how i press the buttons to access the recover-mode the phone just starts up and the LG logo comes up. Then its stuck there
