my x10 keeps rebooting

pls help my x10 keeps rebooting , i have flashed it twice but it didn't solve it. what should i do?
probably u have post in the wrong section. that's why u are stuck in a boot loop.
tell us what u did...so we can tell you where u go wrong. we need more details.
See if you can find out if everything is alright and if everything is compatible with the rom you have chosen. Things you need to check: Baseband, Kernel, locked or unlocked bootloader.
Hope that this will help you.

I need you to specify, exactly what you did to get to this point. What version were you on before you flashed AOKP, which recovery were you using? Etc.

[Trobleshooting] Fixing the touchscreen on P769

I tried to unlock the BL on my new P769BK but ultimately failed. I am on stock now, but my touchscreen has a wonky touch problem, but thankfully isn't mirrored. In order to fix this, I have tried Lelus' method using ADB, but that requires root, and I don't have root at the moment, any ideas on how I can fix this? I have the v6.bin file, can I put it into the .kdz file somehow?
I think you have to put it in the kdz flash thing like how you did with 20b bin, then do a hard reset after it flashes , hope I help!

769 Mirrored / Inverted -- Help Requested
I flashed V20B.00.KDZ and now the phone has a mirrored / inverted splash logo screen and when fully loaded it stays mirrored / inverted.
I have since read and searched for 10hrs trying to locate clear info on how to recover the phone to stock.
I located and have installed v20H.KDZ from LG, still stuck with inverted / mirrored issue.
Could someone please help me recover the phone to a normal screen.
The BL is locked.
Thank you

[Q] Need help unbricking my att e970

So I rooted my att Lg-e970, and things were running great. But then I deleted the google books, and google movies, and then I rebooted it. Now when it tries to reboot I get security error. I can get to the factory hard reset but it says secure booting error Cause: boot certification verify. I cant get it into fast boot, only download mode. I downloaded LG KDZ updater but I am unable to find a firmware file. I tried Original LG FIRMWARE, but it never works for my phone and IMEI. I have tried a few, and searched, and pretty much frustrated right now! lol
So any help would be great!
Thanks in advance!!!
You need to use lgnpst and restore your phone. That will get you back to normal. It's happened to some people in here so you aren't the first.

Here is firmware link. Go to teenybin thread in android development for links and guide for lgnpst. If you want to delete bloatware you must unlock bootloader, use freegee app from playstore.

Ok, one more time. Check the other thread where you asked the same question. Not that thread, but the other one.

LG G e970 AT&T Error boot

My phone LG G e970 from AT&T it says secure booting error Cause: boot certification verify. I cant get it into fast boot, only download mode. PLease any can help me?
I have no idea what to do.
You must have rooted your phone and uninstalled bloatware without unlocking bootloader. LGNPST is the only way to fix it.
If only download mode works , then LGNPST is the only possible way to fix it . Like adfurgerson said.
You have two options and they both need LGNPST.
1. Copy a custom ROM to your ext SD card and use the Teenybin method.http://forum.xda-developers.com/showthread.php?t=2230994
2. Use this link http://forum.xda-developers.com/showthread.php?t=2219953&highlight=jellybean for stock firmware.

Guys, I am just a beginner. Got this mobile 2 days back and in the second day it's soft bricked.. Download mode working in my phone. If you guys suggest which method now I should try I would be happy.
Can I have the custom rom installed directly using the second method mentioned above?
