Does that mean if i get an update and if i am on stock rooted room and i end up in a boot loop i can install the rom and rely on this command line if things go wrong ?

Any idea how I'd pull this off from CWM? I'm in the same boat but can't seem to get storage mounted or adb.

I wasn't able to get ADB on my windows VM, but just managed to get it on OS X and this worked perfectly. Thanks so much!

[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
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
and
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

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.

When Android Keep Booting Into TWRP Recovery

Thousands of android users having this problem, when you install custom ROM and then you try to reset your phone; it keep rebooting into TWRP recovery (not system), even after you flash your ROM again.

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). But anyways try to use the following to get out of TWRP bootloops:
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc

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

FYI: If you run into these problems when using a MediaTek powered device, replace the of= path with

Enjoy!

Tried to OTA update, now phone only boots into TWRP. ROM is still there.

Hi all, I'm having an issue where I tried to do the OTA update, which failed since I have a TWRP installed.
Now, whenever I boot my phone, it goes to TWRP by default. I can still go to the bootloader and start (or fastboot continue) to enter my OS, but is there a way that I can set that by default?
Thanks!

You can't install OTA update if you're rooted/TWRP. First you'd have to unroot.
Anyways to fix your problem do this:
Go to TWRP> advanced> terminal> and type these 2 commands
1)
dd if=/dev/zero of=/dev/block//bootdevice/by-name/fota
2)
dd if=/dev/zero of=/dev/block//bootdevice/by-name/misc
Should get you out of TWRP bootloop

The OTA is in cache... Wipe caches, reboot, and don't accept the OTA again.

TWRP bootloop after LineageOS OTA Update

Hi everyone,
I came into a TWRP bootloop and don't know how to get out. Here's how it happened:
I wanted to start the OTA Update of LineageOS and clicked on install after it was downloaded. The device restarted and booted into TWRP. Nothing else happened. So I decided to do a reboot from TWRP (without doing anything else).
Instead of booting LineageOS it booted again into TWRP.
Now I am caught in this bootloop. The phone always boots into TWRP instead of LineageOS.
Any idea how to fix this?

Solution found
Found a solution by myself:
executing
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
in TWRP terminal solved the issue.
Btw: TWRP recovery from an earlier backup and also clean installing LineageOS did not solve the Problem.

I've encountered too the same problem (my phone version is the h870). Do you have any ideas on why this is happening? I managed to successfully install manually the ota package with twrp (/data/org.lineageos.updater/app_updates) but twrp still keeps looping

I have the same problem. I've tried installing lineage os ota update both via system settings and install manually via twrp but ended up with bootloop. Is there's a way to solve this?

Did you enter twrp via power off - key sequence or via the ota menu?

TWRP Loop

I am in the same boat, but about to try the fix above.
From what I've read elsewhere, this is a known bug in TWRP, and some useful person berated someone else for not knowing about having the correct bootloader (???), but when you're doing an update, that doesn't seem a logical thing?
In answer to your question Mr Kappa, when the system has downloaded the update, you tap to install, and it just does it's own thing, and hey presto, you're stuck in a twpr boot loop. This happens on all models it seems, from LG, Samsung, Moto, and lord only knows how many others, but the fix (and the only fix unless you leave USB debugging enabled) is this "dd if=" command, which is different for each make and model of phone.
***IF you have USB debugging enabled** - reboot to bootloader from TWRP (it will allow you to do this) then connect to your PC, open a command window (assuming you've got ADB/FASTBOOT installed) and type in "FASTBOOT CONTINUE". Apparently this works, but I've not enabled USB debugging so I can't try it (sensible security feature).

Try this one...

I entered it via "reboot recovery" menu on flashify apps.

thx bro its work!!!

I am sorry to be asking at the wrong forum, but does anyone know the dd command for LeEco Le 1s? I am stuck with the same problem and am not able to find any solution for my model anywhere
I would be grateful if someone was kind enough to help me out here.

I had the same issue and was able to fix as the OP said but I wanted to add a couple steps that might not be obvious to some newbs like me.
Turn on the phone and let TWRP load. Connect your phone to your computer via USB and open a terminal window on your computer. Type adb shell. Then:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
Worked for me on LG G6 US997.

Yes, its the root that caused it. in twrp backup the data to mmc/otg/internal -> copy the lineage os zip file, gapps.. to a mmc or otg, in twrp -> wipe cahe,dalvik, data.. exept internal stor-> select storage, install lineage then gapps , dont install magisk/root zip, restore data, reboot system, install update -> reboot-> install rootzip.
next time unistall root then update.

im sorry i am a newbie here.I have the same problem with a xiaomi redmi 7,i was forced to re-install the whole rom with the newest update because of the bootloop.Where exactly do i execute this command? in my computer? or in fastboot mode?

I have the same problem but my pc does not detect my phone when Im trying to connect it and use ADB, I tried 2 different cables. Is there anything I can do or my phone turned into expensive brick?
EDIT: I ignored what my pc was telling me (that no device is connected) and simply went to adb and typed the code above. It works, thank you

yes, using your PC, try searching about adb and how it work first.
here: https://www.xda-developers.com/install-adb-windows-macos-linux/
It aint hard, after that you can execute these:
Turn on the phone and let TWRP load (Even though bootlooping and stuck on the TWRP logo). Connect your phone to your computer via USB and open a terminal window on your computer. Type adb shell. Then:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
Worked for me on Xiaomi 6X recently. Good luck!
