TWRP Boot Loop after OTA

I hit the update tonight not thinking and before I had disabled Xposed.. Now my phone is stuck in a boot loop to TWRP. I have tried to wipe dalvik and cache, tried the adb shell commands that work for most people, tried to restore a backup, but none have worked so far.
I am trying to download the stock file to revert back to stock, but it says it will take 2 hours. Any help for the weary?
Is this the only way to get it working again?

I had a similar issue a couple days ago, problem I think was due to TWRP not having "RT -RM" (? - sorry I'm not looking at the exact text right now or have it memorized) option checked in Settings in TWRP, or possibly due to issue of older TWRP version, .2 and the newer .3 works better. My System directory was unmounted and couldn't come back, stuck in boot-loop until I followed the revert-to-stock directions. I had to download the 2 gig file, taking about 2 hours, and it contained readme.txt w/ instructions and all files needed to revert, but it was very tricky. A .DLL must be overwritten in Windows to get the LG firmware flashing software to work right, and you need the .TOT file. It will work if you are diligent, so don't give up hope. I thought my bada$$ new phone was bricked but finally got it to flash back to stock using that method, possibly similar to the quote in this thread, http://forum.xda-developers.com/showpost.php?p=48434571&postcount=1150, using Verizon instructions / sprint files. You can get it back. Mod will probably lock this thread as it is not development so follow that post I just linked, along with the OP. I am in Windows 8.1 x64 so I think it can work on any version of Windows.

Oh and this thread should probably get locked as it shouldn't go in dev section, mod will probably move or lock it. Hope you figured it out.

What I did ti fix diwnload mode
I took the rom I last flashed. Opened it. went to the system folder and extracted the build.prop (opened it with notepad). Press the find button in one of the drop down menus and find the model number your g2 thinks it is and change it to what it actually is.( in my cause mines had a d801 rom so it thought was one instead of an ls980) I changed mine from d801 to ls980. Saved it (make sure its saved as build.prop). Now go into the rom you originally got the build.prop from and replace it with the new one adb push the rom to the phone in twrp then flash it. Then boot into download mode and flash away

Thank you very much! Work great!

I am dealing with the same issue,
i've had the Optimus ROM installed
and decided to try out cloudy, the phone was rooted and unlocked.
after wiping in TWRP and installing the new rom phone fails to boot to system and goes to recovery automaticly.
i know i could fix this by installing everything from scratch (STOCK).
NBreunig3's solution doesnt work for me either.
what am i doing wrong in the process?

Save the headache, flash stock 4.4.2, towelroot, autorec and start over.

Yeah that is exactly what i did (used ioroot25, and the autorec app is amazing!!), but since i didnt have anything installed on my pc i had to download everything from scratch
and a simple 20 min process became a multiple hours one (trying to avoid that in the future).
anyway i've got the cloudy ROM now and it seems that it is already unlocked so i got that going for me which is nice .

[q] lg g2 d800 + twrp

Hello all.
Over the past few days, I have been attempting to install CyanogenMod on my LG G2, but I am currently stuck on getting TWRP to work properly. I have followed the steps (more than once) on the forum post here (http://forum.xda-developers.com/showthread.php?t=2449670), but it has yet to work. I either get the "fastboot" text screen (two lines), or (now) nothing more than a backlit screen. If anyone can help me with this, it would be much appreciated.
Info on the device:
Rooted
Model: LG-D800 (10o)
If anything else is needed, please let me know. I'd like to get this working.
Thanks

I used this video to bypass all that fastboot nonsense.

Basically all you do is:
!Phone Must Be Rooted!
Download Recovery:
http://techerrata.com/file/twrp2/g2att/openrecovery-twrp-2.6.3.2-g2att.img
Download from the Google Play Market:
>Flashify (for root users)
Open flashify,
Click on 'Recovery image' and look for the recovery you downloaded,
Click on the recovery file,
Hit flash,
Hit Reboot and it'll reboot you into TWRP
And you're done!

I have been having a weird issue flashing the latest trwp versions over stock recovery on my D800, resulting in me booting to fastboot. Oddly, if I flash cwm recovery it works. then from cwm recovery I flash the twrp zip and then I am set. No idea why and I have been able to duplicate it. shrug

Any chance you could communicate the method you used to do this, at some point? I've tried flashing CWM as well, but I've had the same outcome as with TWRP. Would be awesome to get Cyanogenmod on here finally.
Thanks for the replies!

Have you tried the app Flashify, once you are rooted?
Alternatiely, I have put the recovery.img file in the root of my sdcard and then did:
adb shell
su
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

Another app called Freegee will install either CWM or TWRP on there for you.

Well im kinda new to the rooting thing but I believe my phone was only soft rooted. I was trying to install twrp but I got a dead android with a explanation mark or it would go to a black screen after the lg logo.i didn't know I was soft rooted when I was trying this. so after awhile I gave up. my phone still booted normally without trying to go into recovery. recently an update for android came out ( kitkat 4.4.2) so I decided to see if it would work. it restarted the phone to install the update and it got stuck in fastboot mode. i managed to find a way to install twrp using fastboot and adb. i did it but the touch screen was all funked up and i ended up wiping the system i think. just cant win. twrp wont mount the drive eiher. maybe because i have Ubuntu?

well first the reason your phone died is because of the update you did after you had broken your stock recovery, if you have twrp currently there are two things you need to do:
1)get rid of the update using this
2)adb push/sideload a rom and try to flash or try and get in download mode to restore to stock

no fastboot is only for restoring the phones stock partitions but if you use twrp sideload feature it should flash it once it's done copying it(I know that's how it works with philz)

I'd recommend flashify to flash recovery images. You can download it from the play store. So easy to make a typo and mess things up with adb and dd.
You could do it with a terminal or adb shell. Say you store the image in /sdcard
Code:
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p14
Verify mmcblk0p14 is recovery before you try this. I'm pretty sure that's right, but I don't have my tablet right now and you can make a serious mess of your device this way if you overwrite the wrong partition. Check it by listing your partitions with this:
Code:
su
ls -al /dev/block/platform/*/by-name
By default this little tablet does not have fastboot, but you can enable it with this method. I've zeroed out my laf partition and verified I can boot into fastboot mode, but I've never actually used it to flash anything. It just seemed like a good idea to have fastboot available to fall back on rather than LG download mode since there was no kdz available for the V410 for a long time.

Thank you! the thing is i bricked my g pad, i really dont know much about the tab because the lack of support it has. I was using it with cm12.1 and i use a stock recovery founded in Android central to revert back to stock, but in TWRP i flashed the img as recovery and also as boot, so the g pad entered in a bootloop were only enters in stock recovery, my Windows 10 laptop doesn't recognize the tab when in adb sideload, and doesn't know much about adb Shell, i'm following the comandas you wrote but i'm always getting error: closed.
i know how to get back to stock using the kdz, but using the kdz will make the partition issue and will have to folllow a looong looong process.
If you could give me a hand with this i would really apprecciate it

Sorry I've never encountered the adb closed problem myself, but I have heard about it before. Some people have reported the following series of commands fixes it:
Code:
adb usb
adb devices
adb kill-server
adb start-server
The first two commands normally don't really do anything and its pretty obvious what the second two do, but some people have reported success doing this.
Some people have reported the closed error was fixed by updating their adb binary. If you're using the android-sdk update platform-tools, or if you're using a standalone adb consider looking for an update for it.
Good luck. That procedure to get things back to normal following using the kdz to restore sounds messy.

I flashed stock rooted 4.4.2, and I want to OTA to Stock Lollipop, but it says there is no update. Any ideas of how I can get back to fully stock? Would flashing this stock recovery make it work? Is being rooted blocking the OTA update from seeing an available update?

If you applied an OTA with a custom recovery installed it might soft brick your tablet, but I don't see why that would stop it from detecting and downloading the update. It is always safest to flash stock recovery, fully unroot, and undo any modifications you've made to /system before taking an OTA, but some devices are more picky than others. With what you're describing I'm afraid that even if you do unroot and flash stock recovery your tablet still won't find the OTA.
Do you have a nandroid backup of an unmodified stock ROM you could restore?
And just so you know that lollipop bootloader is not vulnerable to the bump exploit, so no custom recovery or ROMs if you get it to apply.

Whenever I type "reboot recovery" in terminal emulator, it boots straight to factory reset. I have tried this multiple times with both dd and flashify. Do you know what causes this? I'm downloading the OTA right now, I hope it doesn't wipe then too...

please help
i was a dumbass and accidently flashed my boot instead of recovery do you by chance have a boot.img that i can use to reflash my boot.img please help as im really stuck..thanks in advance

Download the timmytim stock ROM, and extract the boot.img from it. There are probably quicker ways, but having the stock ROM on hand is a good idea.

Thank you...
I resolved my issue i had forgotten in my haste i posted the same question in two different sections. However after fixing everything my tablet was broke not the out glass but the inner display. I cant afford another one or a replacement part to even fix mine. So unless i can find one someone who bricked theirs completely or get a handme down im tabless for awhile.... Thank you though for the reply. The original boot file wouldnt work properly i had to use the boot file from the stock rooted rom and not the timmytim deoxedized rom.. i dont know why unless the bootfile is specific to each rom. Maybe i did something wromg during the flash. But i had gotten it fixed nevertheless.

[Q] LS980 security error bootloop help

Hello everyone, I'm gonna need your help with this. I know very little when it comes to rooting/flashing and all that jazz. So last night i rooted my ls980 with the a LG One Click Root application on my pc and then installed a recovery with AutoRec. Everything seemed fine until I tried to flash a rom (Paranoid) and it wouldn't work. I restored my backup but now I get in a bootloop with the word "security error". I am able to get into recovery (twrp 2.8.6.1), but not download mode, and have tried using the these lines in the terminal command: "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota" and "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc" with no luck. is there anything else that I can do? I deeply appreciate your help
