HELP BRICKED LG e739 MyTouch

Hi there, I NEED URGENT HELP!
I bricked my e739, and I am running out of the options. All I see is the LG logo, I can not access my recovery mode, I tried numerous times (and before i succeed now the logo doesn't even blink it stays the same) hard reset...nothing, tried adb recovery (does not see the device).
So here is the story, I successfully updated my ROM to e739 Nightly 6. After using it for a bit, I decided to go back to stock, and just wait until all bugs are worked out. So i tried to go back to my backup that I made of stock, but no dice it got me in recovery loop, after that I tried to go factory reset, nothing. I couldn't find any way to go back to stock, so I made it my mission to reset the phone. Here where I [email protected] up, I read that using e730 (older) rom will let me out this loop and allow me to get back to the stock. So here are my steps of mischief: installed Nightly ROM 12 for e730-> then I flashed the device to LG optimus Black (dont ask why...I realize it is stupid) -> and through privacy setting clicked for factory reset. Now I am in this bootloop.
I will take any suggestions please help, it really sucks in the stone age, with edge speeds.

Hold Power and Volume Down, then after 3 seconds hold Menu and Back (not home) and when the LG logo pops up, release the Power button but keep holding Vol-, Menu, and Back.
It may take some try a to get it right.

And make sure to pull the battery and put it in again when starting to hold the Power and Volume Down

This sounds like it might work, but O got another tiny bit of problem, I been trying to reset it so many time the phone wont turn on anymore unless it is plugged into power source. I am not sure what to do now. I want try to hard reset your way but I can get the phone to respond anyway unless it is plugged in.

Well plug it in lol
I've had several bootloops myself trying to get to stock, but i always got to acces recovery and flash CM again. And now that tthe RC was released, i don't see why i should return to stock.

1) Pull the battery out
2) plug ur phone to a computer (on the screen you should see a battery icon indicating the phone is charging)
3) locate your adb folder in my case it's c:\adb once your in there write adb reboot recovery...that should get you to the recovery....
good luck..

Hello, I have been having some issues with my LG E739[KW], the device was working properly. I rooted install CLOCKWORK custom recovery. After that I installed, CM9 then later CM7, the CM7 worked okay but i opted to revert to Stock So I used the LG SUPPORT TOOL to flash back to stock ROM. however after having done so the phone has been stuck in boot loop ever since. After flashing the stock ROM the phone never made it past the boot screen, and when I remove the Battery reinsert it and try to turn the phone on I get the S/W update screen. Where I have to flash it again for the phone to boot only to be stuck at the boot animation. I have also tried flashing it VIA the KDZ method but its the same result. Please Help !!!

[Q] Jellybomb start up problems

The problem only happens when I reboot or turn on the phone. When it boots up, I get multiple results. A: It boots up normally (not a problem) B: When it gets to the samsung screen, it freaks out and reboots itself again and again. It's like it's struggling to boot up. One time it got to the gs 3, but then it looped back. C: This just happened today. I booted up and it went pass the samsung screen but when it got to the gs 3 screen, the screen turned a faint pink and it stayed on that screen.
This just happened right after version 8. I know 10 was messed up but on 9 and 11, this problem persisted. Also,I don't think the issue is the phone, since I don't have this problem on other Roms. If I'm wrong please let me know .
Any suggestions, advice, help, etc is welcomed.

Please... i really need help.

I suggest you start over, this will remove any corruption and gremlins you have klinging to your phone..
http://forum.xda-developers.com/showthread.php?t=1904099.. Then re root and flash anew.

I unrooted, went back to stock, it did a factory reset so no bugs should have been alive. I re-rooted, made a backup, did a factory reset and wiped dalvik, then I flashed the rom zip and rebooted. It gets stuck on the Gs III screen. I waited like 5 minutes and it didn't move. My battery was at 50% so I just put it on the charger and tried to boot up and it went through to the set up screen for gmail.Just to see if it was coincedental, I did another reboot but this time it got stuck again. It sounds like a system problem but i'm not sure.Like i said earlier, this only happens on Jellybomb.
Any other ideas?
Edit: I've tried switching recoveries but it doesn't fix it.

Sigh.

At a loss... SM-920P, MM, continuous reboot loop no matter what

I upgraded to MM back the beginning of the month, tripped my Knox bit (I had rooted via PingPong root on Lollipop), but I was eager to go to MM and try Xposed so I could improve the horrible battery life.
I had the system working fine, rooted using CFAR, and no problems. Randomly, about a week ago, it just "lost" root. I wasn't sure why, and CFAR from Odin wouldn't bring it back. I did a flash with SuperSU in TRWP yesterday and it worked, and I did a NANDroid backup, saved it to my computer, and installed Xposed... On a stock ROM.
And my phone has been a continuously rebooting brick ever since, no matter what I do.
So, I've tried everything I can think of. Because my data was completely backed up, I did a complete wipe, and nothing. I tried flashing the Xposed-uninstaller.zip and that supposedly worked, but the phone reboots about 53 seconds after it starts up, continuously, no matter what.
I've tried the default MM firmware, tried letting it go through it's paces on its own (but it just reboots every 53-57 seconds), and also tried with a fresh clean default MM ROM, which does dump TRWP, then restart into the default bootloader, have it dump the cache and do a complete re-wipe, and nothing. Still restarts.
With the stock MM firmware load, the first boot it always stops at 32%, reboots, and when it comes back up it sometimes makes it through "optimizing xx of 30 applications" but always reboots and comes back to it over and over, ad infinitum. Sometimes it makes it to 30, usually it doesn't, but it always fails, reboots, and comes back to the same menu on a stock ROM.
ADP and MTP in TRWP work fine, and all my data is backed up. So, I'm willing to do anything to the device; nothing left on it to care about (I already tried NAND erase in Odin and format partitions in TRWP). It still continuously reboots at around 53 seconds.
I've also tried custom ROMs loaded up from TRWP (Renegade 1.1 and TeamSPR V3). They apparently load - everything looks/works great from inside TRWP - then invariably they reboot at about the 53 second mark. Can't even get Renegade past the boot screen.
Nothing was done hardware-wise to break it; the Knox bit flipped three weeks ago, and the SuperSU upgrade had been working fine. The action that killed it was attempting to install the Xposed framework on a default ROM that only had SuperSU installed. But I've since installed a default ROM and ran the Xposed uninstall to no avail. The uninstall Zip in TRWP gave all the right responses that it worked, but it still rebooted 53 seconds after restart. Continuously.
I don't even know how to go back to Lollipop because attempts to load G920PVPU1AOCF in Odin gives me an immediate failure of "SW REV. CHECK FAIL. DEVICE: 3, BINARY: 1," so downgrading appears to be out of the question.
Someone has to have seen something like this before or there's something I'm missing. About the only thing I can think of is to try a custom ROM install and force the Xposed framework again without even letting it boot up (because it won't anyway) from a TRWP install. I'm going to attempt that while hopefully someone else comes up with ideas for me...

rebooting
people have had luck letting their phone battery die completely and rebooting after charging just a little bit. make sure its completely discharged before rebooting

Stick it in Odin mode and let it die, once it gets to the point where you cannot turn it on anymore, it's good :good:

Samsung Galaxy Tab S stuck in bootloop after flashing official ROM and factory reset.

After recovering from a previous bootloop issue with my Tab S, I'm in the same situation after flashing the official Samsung stock ROM for KitKat 4.4.2 via Odin.
When the ROM was first flashed, the tablet began working as per normal with the exception of it taking 10+ minutes to fully reboot and the device somehow restarting itself and loading the display within a second. However, after a few days, I kept receiving pop-up windows on the tablet stating that different applications (most of them I didn't have opened or running in the background at the time) weren't responding. A couple of days after that, more of said pop-up windows kept appearing on the screen, sometimes freezing the whole device until a push notification appeared in the background or the device force-rebooted itself.
I flashed the ROM again once or twice and cleared the cache partition to see if that made any difference, which it unfortunately didn't. I also removed the microSD card and SIM card, force-rebooting the device without them, and then with them when that test failed.
Now, for roughly about a week, the tablet has been stuck in a bootloop (the splash screen animation) where I have left it to drain the battery, leave it for about a day or so, and recharged it to 100%. So far there hasn't been any success.
Today I finally factory reset it to see if that may help, and the only thing that has changed is that the sound of the device rebooting is now playing when it does transition to the loading screen, which I had turned off previously when the tablet was still working.
Is there anything else that I may have missed that could help it work again? It's not rooted (and I would very much prefer to keep it that way) and has not had a custom ROM installed or flashed onto it. It can still enter Download Mode and Recovery Mode, but other than that and being about to use the Power-Volume Down technique, there's not much else I can do with it so far.

Factory reset, install stock firmware, wait ten minutes and you should be good.
But why kitkat? MM is available and working well.

It worked! Thank you so very much!
And I'm not a huge fan of updating my Android devices due to past experiences, but if this happens again, I might just update it to Marshmallow.

i love you man...this worked for me too...thank you...now i need to reinstall TWRP again and see what's cooking......

I had this problem recently too, with the added complexity that the "Factory Reset" option in recovery wasn't working -- it would say something like "MDM does not allow factory reset" and then just reboot.
Fixed it by directly flashing TWRP with heimdall, then booting into the new TWRP recovery, performing a factory reset, and then rebooting the OS. This time it got pass the bootloop.

i flashed new twrp for T700 it's bootloop cannot enter the twrp menu keep bootlooping ...what's the solution for this?please help

Help ME!
What are "stock firmware" and "MM"? and where to get it?

I've replaced the power button thinking it was a hardware issue but now I'm not sure. I've also installed a few different stock roms but still have the same problem. Does anyone have any insight as to what could be going wrong and what I can try to get it fixed? Thanks for any help you can give. The device is a Samsung SM T-800

My tablet updated and now I can't get it to do anything...

My Galaxy Tab S prompted me for an update last night. I was at 5.0.2, so I'm not certain what I was getting upgraded to but it was about a 190MB download. The download went fine and the install seemed to go OK. However, at the end of the update install, the tablet rebooted, and that's when everything screwed up. It went through a normal reboot sequence but, when it started to come up like it was going to take me to the home screen, I got hundreds of error windows popping up one on top of the other. They all said "Unfortunately, this has stopped." or that has stopped, basically running through pretty much every default pre-installed and me-installed app on my tablet. And they kept appearing faster than I could press OK. I have just a black screen with these white error boxes. I'm never able to get to the home screen at all. I've rebooted. I've completely powered down and waited for several minutes before booting. Nothing seems to help. I keep getting a normal boot sequence, right up until the point that it would relinquish control to me, and then these same hundreds of error boxes and no home screen or any sort of control over my tablet. I have no idea what to do.
Has anyone ever heard of any behavior like this or know what I should do?
Thanks.

try to enter the recovery mode by pressing home+vol up+power button. and reset your device
or you can download your full firmware and flash it using odin.

Just got up for the day and saw your response. I'm on nights right now, sorry.
Thank you very much for your reply. I was able to get into recovery mode. Just to clarify, when you say "reset", are you saying a reboot (the first option) or wipe data/factory reset (the fourth option)?
EDIT:
You can disregard. I went ahead and rebooted, and that did what I figured; pretty much nothing. Basically just rebooted, got out of recovery mode, and booted right back into the state that it was in before, which was screwed up. Factory resetting now.
Thanks.

OK, system wiped OK and it's restoring from a Google Backup right now. So, I guess we'll see how it goes the next time I try to update. I have the Wi-Fi version, just standard SM-T800. Isn't Marshmallow available as an update now? I'll see how things go I guess and see what updates are available.
Gotta remember recovery mode, for when all seems darkest!
Thanks again for your help.

OK, so, my tablet is back up and running, but that update won't install. It isn't causing the same problems as before, but it still won't install. I'm at 5.02 and the update is 190MB. It downloads and it starts to install after I accept the EULA. The screen goes black, the little Samsung logo pops up, then the little Android guy comes up and it says installing update 0%, waits for about two seconds, then the little Android guys is on his side with his cover plate up and it says error, then reboots. I can still use my tablet, I just can't install this update, whatever it is. I'm pretty sure it isn't the Marshmallow update, because I'd heard that was up over 1GB. Still, if I can't get this update, whatever it is, I doubt I'll ever be able to get the Marshmallow update.
Now I'm happy I have my tablet back, but frustrated because it won't update.

definitely it already has MM update. you could go to Odin way. Update it manually. can download the firmware here.

Yeah, I was thinking the same thing. It doesn't seem too hard. I'm reading up on it now. I'll download everything I need and possibly try it this weekend. I intentionally haven't reinstalled a lot on my tablet yet, thinking I was going to go that route.
Hopefully, that will take care of my issues.
Thanks again for the advice.

Well, updating with Odin went off without a hitch. After it had updated, I performed a factory reset, just to be safe, and reinstalled everything. It's running great now and I sitting pretty with 6.0.1.
Thanks again for your help.
