Howdy all!
Did you install TWRP and then take the OTA, now you can't get your phone to boot normally, but you do see TWRP?
Here's the easy fix:
If you have ADB access, plug in your phone and run this:
Code:
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Then you should be able to successfully reboot your phone via the TWRP menu option, or via a simple reboot command in adb.
If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
After that finishes, you can reboot and continue on your happy way!
Let me know if this helps anyone!
As usual, I'm on #lg-g2 in Freenode as IOMonster, if I'm around I'll be happy to help wherever I can.

if that doesn't work, try autoprime's with added step for misc.
after that you can delete the files located at (using es file explorer) device>cache>fota

LG G3 Stuck in Recovery Fix
Background
This thread is to help those who get stuck in custom recovery every time they try to boot into the rom.. usually after trying to take an OTA. Now that we're all rooted and unlocked this might be needed soon. Inspired by IOMonster's [FIX] Installed TWRP and now you're stuck after OTA? thread for the LG G2. Sometimes wiping FOTA was not enough and wiping the misc partition was also needed. But wiping the entire partition isn't the best idea. I've made a flashable zip to automate this process to properly fix being stuck in TWRP/CWM due to "stuck fota" or "stuck misc"​Fix
Flash LG_G3_Flash2FixStuckRecovery.zip to backup the current stuck fota/misc partitions and then fix them to allow proper booting.
Flashing LG_G3_Flash2FixStuckRecovery.zip creates a backup of your FOTA and Misc partitions in the /sdcard/FOTAnMisc_Backup/ folder.
1. Download the LG_G3_Flash2FixStuckRecovery.zip and place it on your phone. You can use TWRP's MTP feature to copy it from computer to phone, use OTG w/connected storage containing zip or use adb push to get the file onto your phone...
Code:
adb push LG_G3_Flash2FixStuckRecovery.zip /sdcard/
DOWNLOAD FROM CODEFIRE HERE
2. Flash LG_G3_Flash2FixStuckRecovery.zip in recovery or use adb commands below to fix boot issues..
Code:
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc bs=256 count=1 conv=notrunc
reboot
If you are still booting into TWRP/CWM then you may have accidentally flashed the custom recovery img to the boot partition slot instead of the recovery partition slot. Reflash the rom in TWRP/CWM which should fix the boot.img... or download the required boot.img, place on root of internal storage ( /sdcard/ ) and flash the boot.img in TWRP/CWM...
Code:
dd if=/sdcard/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
reboot

[Q] can't change CWM from 5.8.3.4

I'm stuck with only the ability to go into recovery while the rom doesn't boot and backups are stored on the uSD.
It's the Clockworkmod Recovery 5.8.3.4, and it looks like it doens't read from my uSD. I am able to connect via adb and push an other recovery.zip, that does work with the uSD, but it looks like the flashing goes ok, but when i reboot, i just end up in clockworkmod recovery 5.8.3.4 again.
adb push works to push multiple recovery.zip, but when i try with some rom.zip, i get, maybe because of the filesize, a 'protocol failure'.
I tried easyflasher 0.8.3, but it also doesn't have any effect.
Is there anyone who can help me guiding what else i can try or what the problem could be?
Try these steps
1: use adb to push a new recovery file (which you already did)
2: flash the zip
3: use the adb shell to execute the following command
Code:
echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0

Installing CWM Recovery on Unlocked RAZR M via terminal emulator

I ran the boot loader unlock exploit successfully. Had troubles flashing recovery. I don't own a computer. Hence my dilemma. Is it possible to flash custom recovery with terminal emulator? I have searched other forums and sites for hours now. I've tried the flash_image command. And just about any other options that I've found. What am I doing wrong? Its it even possible on the RAZR M? Do I have to use fastboot? Any help would be appreciated.
Here are some flashable recoveries. I have not tried them out, but I heard they work.
http://batakang.com/ftp/?dir=devs/mhous33/XT907/recovery-flashable_recoveries
You need to use the dd command and the full /by-name path to the recovery partition in terminal from root shell.
If you download the latest TWRP recovery image for scorpion-mini and rename it to twrp.img for simplicity then place it on the root of the sdcard then you would use the following commands to write the file with dd in the terminal emulator.
su
dd if=/storage/sdcard1/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery bs=4096
I strongly recommend backing up the current stock recovery first because without access to a PC you may need it to restore yours in the event of a problem.
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/storage/sdcard1/recovery_original.img bs=4096
That will save your stock recovery and you can restore it using the first command and that file as if.

My gf is on the ls980 with sprint and she is rooted on the optimus rom. twrp 2.3.4. lokified. she took the sprint ota and now the phone only boots into recovery no matter what i do. restore or load a new rom wont work. Please help..
umm
you said TWRP 2.3.4 did you mean 2.6.3.4? i know TWRP 2.6.3.4 supports OTG cables. If you have an OTG cable you could put a rom on a flash drive and it and try to flash it.

Saving LG G2 after unwanted OTA caused boot loop

This works on International D802. I had stock rooted rom with CWM (6.0.4.4), Xposed ( G2 Xposed, G2 tweakbox, Advanced Power Settings, App Settings), Tasker w/ Secure Settings and whatnot. So I applied OTA. Not good for the phone and the Ingress Ressistance. I was stuck at LG screen for 2 sec, reboot, rinse and repeat. Download mode was no go. Luckily I was able to enter recovery mode. Tried to restore..no luck. And after staying up till 4AM (thanx to the xda forum). I tried G2 back to stock with kdz thread. Couldn't enter download mode. I changed few USB cables, three comps and voila it entered DL mode. Unfortunately that was on Linux box...so no LG flash tool. Arghhhhh.
Next step...Linux needed, no knowledge, just sensible use of copy/paste. Enter recovery, wipe everything you can. Reboot to recovery and yes, root please. Now you should have adb. Do the following (thank you thecube)
Code:
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
If you get any errors...don't worry. I managed to execute only line 2.
Reboot to recovery w/ root and again wipe everything (it worked for me, might not be needed), and copy/paste again.
Code:
adb shell
mount /data (disregard errors)
mkdir -p /data/media/0
exit (do not forget to exit shell)
adb push rom.zip /data/media/0
adb push rom.zip /data/media/0 ( where rom.zip is up to you..i used Black Pearl ROM)
Now watch that coursor. If it is not blinking...you are almost there. When push is completed, install rom. zip as usuall.

[Q] Is it possible to repair my installation post official updating?

So I did a number on my phone in a half asleep stupor I allowed an official update to go through while running a custom recovery and debloated kitkat. I can't believe I did this to myself. Is there anyway to repair the installation other than wiping the phone again? It was one of those mini updates, but now I boot straight to recovery instead of the operating system.
I am in the same boat you are man. I hit update now instead of later and the phone reboot into recovery and won't boot the ROM. I tried restoring a previous backup with no luck. I'm on a rooted stock ROM running twrp 2.7. Hope someone can shed some light on this.
I found an answer!

Have you typed the two commands in TWRP

Here is the thread:
[FIX] Installed TWRP and now you're stuck after OTA?
So here is what you do:
1) Boot into recovery (TWRP)
2) Go to Advanced and then Terminal Command
3) VERY CAREFULLY TYPE IN EXACTLY THIS:
"dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota" then RETURN
"dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc" then RETURN
Reboot and it should have fixed it up for you.

I got my phone less than 24 hrs ago and have dealt with this the entire time. Not only do I get stuck in recovery but when I do use the terminal code to get out of it, I get stuck in reboots after any ROM installation. I have seen many users having both issues and find it hard to believe there hasn't been some kind of fix. I know not all are caused by the same thing but many I'm sure are.
Boot to TWRP recovery, open Terminal inside TWRP and type:
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/misc
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/fota
Than reboot.
(May in rare causes loose TWRP but u will get out loop - be patient takes sometimes 7 Minutes+ for boot up the ROM)
Worked for me.

Actually, you shouldn't use the above commands unless the following command doesn't work. That used to be the recommended method of getting out of TWRP, but it was realized that using the first command wipes your misc partition and then you end up with a Mac address that changes in every reboot (there is a temp fix for this I have a guide for).

I got in that Bootloop by doing a Factory Reset with Root and TWRP. Formatting and Flashing the LG-H85020D-Flashable.COMPLETE.zip just ended in TWRP again.

Yeah - be careful with this - I did this and bricked mine - it went from unable to boot into Android to unable to boot fullstop... eventually managed to get it restored to factory (using LGUP), but MAC addresses all reset to 0's on every reboot - so now need to run macchanger on every boot...

I tried this command after flashing lineage rom on my Nexus 5x. After flashing the rom, you initially see the Lineage logo, but it never boots, it just goes on into recovery. I flashed the rom 2 times, but same effect. After this I tried the command up here from the terminal, but nothing changes. Every time I reboot, it just boots back into TWRP. What do I have to do if this command does not work? Anyone have an idea? I saw the other commands in this thread, but it seems like most people don't think it's wise to execute those, so i'm just asking to be sure.
I also tried restoring the original backup of the phone I made in the first place before flashing lineage, but that just ends up in a bootloop where I end up in a screen with the google logo and the unlock sign. I followed these instructions to the letter, but somehow the phone is now bricked.. https://wiki.lineageos.org/devices/bullhead/install
So, no ideas here? I frantically tried getting the phone to boot into the bootloader, and after I don't know how many reboots it finally responded to my holding the vol down button, and got into the bootloader. From there I was able to flash back the entire phone to factory settings (I did not want to risk having to try over and over again to get it into the bootloader) and I'll keep it at that for now. I'm pretty experienced with custom roms on several Nexus 4, 5 and Galaxy Note II, but I've never had anything like this after flashing a rom.
Worked like magic the first time around. Thank you so much your your skills and sharing it
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
