[Q] BRICKED! Bootloop VZW HELP!

Dear XDA,
I have tried all I can to fix this problem. Let me explain how it all started.
I was using my phone normally, running the same custom rom ive been running for the past 6 months. I went to turn on wifi then turned off the screen. Later when i went to check my phone the screen would not turn on, so i performed a battery pull. After that i saw the normal google boot screen and then the custom rom boot screen. It stayed on that screen for a few seconds and then went back to the google boot screen. It then did this over and over, ive left it on for an hour once and it kept doing the same thing. Only way to stop this is with battery pull.
So what can i do with the phone:
I can access fastboot
I can access download mode
What have i tried:
I tried the following methods:
1) Flashing a Back Up
2) Wiping data, flashing a rom and gapps
3) fastboot adb http://rootzwiki.com/topic/13819-how-tovzw-return-to-factory-state-unroot-and-relock/
4) ODIN http://rootzwiki.com/topic/27050-vzwodin-files-needed-for-odin-winstructions/
The same issue continues even after successfully completing these methods. Im now down to my last strand and hoping the great xda community can help me.

Fastboot seems the best solution to me. What exactly went wrong? Also you could try a OMAP flash.
Sent from my Galaxy Nexus using XDA Premium HD app
To be honest I have no idea what happened. It happened out of no where didn't flash a new rom or anything. OMAP flash? Never heard of it but I'll definitely look into it and try it. I've tried fastboot method and still got the same problem sadly
Really hoping this isn't a hardware issue
I just tried an OMAP Flash and still have the same problem. Ive moved on to a new phone but I still want to get this one working. Any other ideas to fix this problem?
Got into the same problem as yours. I googled around, and most people fix this problem by flashing stock image. Basically wipe your phone clean, e.g system,data,cache etc. and then flash in the stock image u downloaded from google website throught fastboot mode. I tried that method, but my phone is still stuck in bootloop. You can give it a try and see if it works

[Q] Problems setting to stock

I have a little experience with custom roms and rooting, but i have not yet set anything back to stock. I tried to set my GT-S7560m back to stock with a stock rom from sammobile(dot)com. I flashed it with odin like normal, and it said everything was good, but the phone never booted.
It got past displaying the model but got stuck at the samsung flashing while booting. I have left it at the screen for 30 minutes hoping it would boot, but no luck. I removed the battery for a day and tried to boot again and still no luck.
I read somewhere that sometimes help if you can clear the cashe but i can not enter the recovery(I can still enter download mode). I have noticed when i try and enter the recovery when the phone is plugged into the computer it just keeps saying disconnecting and reconnecting, with nothing on the phone it self.
I also tryed to use samsung kies to reset it but it just told me this device was not supported or something similar to that.
Now i have tried anything that i have found, i am willing to try just about anything, any help or input would be appreciated.

[Q] F460K won't flash stock kdz

I've tried to tune headphones output gain and at some moment phone stuck at boot.
Since then I can't reach recovery. The best I've got is the "download" mode.
"Ok, fine" – i said – "show me the fireworks!" and tried to flash the brick back to stock with LG Flash Tool 2014 and the downloaded KDZ-file. But recovery process always stops with unknown error at the point of 49%. I've tried restarting it several times.
Trying to boot phone shows updating android first, then screen changes to LG logo and that's all. It stays that state forever.
Any advice would be very appreciated.
still holding a brick... Help! :crying:
OK, I've solved it.

LG G3 D850 (AT&T Variant) Bootloop after Stock Firmware Restore

Hey guys,
I used this guide to restore the stock firmware: http://forum.xda-developers.com/showthread.php?t=2785089
It didn't succeed. Near the end, when phone rebooted, it got stuck in a bootloop.
I see the LG logo, the android man for a few seconds until it restarts again.
What should I do? I tried running the factory reset but that too does nothing but reboot it (again in the loop)
I am also having this same problem, if anyone could help/shed some light that would be great
Me too. I take days trying to find the solution.

Bricked Device! Would appreciate help.

Model: LG G4 H810-About 2 weeks ago, I was messing with Xposed Framework and some modules. I restarted my phone as one would do after enabling a new module. While rebooting, my phone got stuck on the AT&T splash screen. I waited a few days and still the same thing. I used the LG Flash Tool to try flashing a KDZ, but this sent my device into a bootloop. I tried doing it again, but the phone cord accidentally came unplugged. Now, whenever I power on the device, it goes straight to download mode. I can't boot to safe mode, or to recovery mode. The computer says that the device is corrupted and unrecognizable. Is there any fix?
Still an issue?
Hi there and I hope you have had luck with your phone. If you have not I can help you out with this situation. Please let me know if this is still an issue.
:good:
