[Q] cyanogenmod initial boot bootloop, help?

Hello, I had done a backup from adb backup, and after that I decided to unlock my bootloader with ./fastboot oem unlock, then I installed clockworkmod touch and booted back into android. I tapped no for the recovery fix and yes for root. It went into a bootloop at this point.
After I saw it looped, i decided to load clockwork and adb sideload cm-10.1.3-mako.zip. After I rebooted, up came the cyanogemod boot animation and it's been looping for about 10 minutes now. I stopped and started it about 3 or so times by force shutting down the phone, and i tried to go into clockwork but it wouldn't even load the bootloader. Help?

Did you do a full wipe before installing cyanogenmod?

I did not. I probably should have though.

Yes, thats probably the issue. Go back into recovery, do a full wipe, then flash cm. Should work.

Yeah, it worked. I just formatted all the partitions then re-side loaded. However now, I can't do a ./adb restore backup.ab because whenever I try to and enter my password, it will just say backup ended right after it started.

Soft bricked Zenfone 3 still have TWRP

I have a Zenfone 3 that while trying to unroot I have soft bricked. I can get into TWRP recovery, but after installing the tizen ROM, I can not boot into it, but can still access the TWRP recovery. Is there a toolkit or any suggestion you might have as to how I could fix this issue.

Do you have an official recovery? If yes, you can recover back your device again. Just use 'adb sideload <filename>' to do this.
I've also trying to unroot my device and end up in boot logo, but after flash the official ROM, it's finally work again. Also my data (/data) isn't formatted.

TWRP supports adb sideload but there's no point flashing stock recovery, TWRP is superior in every way.
Go into TWRP, plug in your USB cable and it'll mount your sdcard . Copy the firmware onto the sdcard and install it. Perform a wipe cache/dalvik and reboot.
How are you removing root?

I used a app called KingRoot while I was on the bus, it caused the phone to freeze, after about 10 mins I hard reset the phone and it has not worked since.
I tried to sideload the stock rom, but it will not accept it. I think I may have something to do with the bootloader. I think my TWRP recovery could be in the Android partition, but I am unsure.

Forget sideloading it, edit the update script in the firmware, see this
thread, part 1, step 2-4.
Then copy the firmware to your sdcard (like I mentioned above) and install it. You can use the guide here, tip #4. You should read the entire guide afterwards.
if TWRP loads when you select recovery, it's on the correct partition. You'll have to reinstall TWRP after you flash the stock Rom again as it'll update recovery as well. Then create an nandroid backup, tip #2 and you're set.

Hy Wang.. I followed your guide - modified updater-script, but I can't install the stock rom .zip from TWRP.
It says "can't extract updater-binary", I tried few times thinking that the file is corrupt, but the result still same.
FYI, I use stock ROM "UL-ASUS_Z012D-WW-14.2020.1709.68-user.zip", and TWRP 3.1.1.
Please help me if you have experienced it before. Thanks

@rzahunn
I've never had that error before and you're on the latest version of TWRP so I'm going to guess it has to do with your modification of the updater script.
You edited updater-script not updater-binary, correct? There are two files with similar names

There's a detailed guide by @kyle_l88 on how to return to stock.
Here's the link: https://forum.xda-developers.com/zenfone-3/development/how-to-to-stock-rom-recovery-zenfone-3-t3666223
Do note that the original recovery link is dead. The updated link is: https://mega.nz/#F!LIhwiCia!b_pyuHXS9E7f2VbyXcLyXA

TWRP Bootloop
Sorry if my reply is irrelevant, but I need some helps.
I am also using Zenfone 3, but stuck in TWRP bootloop.
I cannot flash using fastboot (not detected on PC), reflashing ROM doesn't help either.
I've tried all the possible methods I found on Google, such as dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota method but still has no luck.
Restoring backup would end me in TWRP too.

@Xytce
Are you factory resetting after you flash? Clearing cache and dalvik? It will take 5-10min to boot up initially after that.
Otherwise, try the guide Rizzed referenced.....as long as you have the correct firmware and TWRP flashes successfully, there's no reason it shouldn't work that I can think of.

I've managed to fix the bootloop after following the guide. I missed that somehow, thanks for pointing that to me.

Need Help; My LG G6 (H870) keeps booting in TWRP and I can't install stock ROM

Hi,
I unlocked the bootloader of my H870, installed TWRP 3.1.1.0 and SUPERSU. Everything was working great untill I decided to restore my system defaults to make a fresh start with my G6. After choosing the option to restore system defaults, my phone rebooted and it booted into TWRP. I rebooted my phone and it kept doing this all the time.
I decided to look for a stock ROM and flash that ROM.
I succesfully flashed the "LG-H87010f-Flashable.COMPLETE.zip" ROM (from autoprime's post) trough TWRP. But this did not work. I even wiped all the data from my phone (even system) and flashed the ROM again; still nothing.
Before having this issue, I had the same Baseband version, Kernel version, Build number. Only the dates and the Software Version are different.
I had the V10b-EUR-XX Software Version installed on my phone. I see this is the 10f version. I guess this should not be a problem right?
After this I took these steps solve this issue:
1. Downloaded new LG Mobile Drivers (LGMobileDriver_WHQL_Ver_4.2.0)
2. Downloaded and installed LGUP. LGUP doesnt recognize my phone as a LG G6 and this method did not work for that reason.
Fastboot mode is working on my phone; I can reboot my phone trough the commandline on my PC and things like that . However, my PC is not recognizing my phone as a LG G6 device in Fastboot mode.
My PC recognices my phone as a H870 when in TWRP. In Fastboot mode it recognices my phone as Android Device.
3. Installed LG Bridge for more drivers; did not work either
4. Downloaded Uppercut, but it doenst work without LGUP.
4. Looked all over the internet to find a Stock ROM in .zip or .img format; found nothing
5. Downloaded WindowsLGFirmwareExtract-1.2.6.1 and tried to extract the H87010d_00_OPEN_EU_OP_0327.kdz file. I extracted it into .bin files, but they were not usable. After that, I combined these .bin files into a system.img file. But that .img file was bigger then 5 GB and for that reason it was not usable to flash trough Fastboot or TWRP.
7. Looked for other methods to obtain a H870 Stock Rom, including another extraction method, but I cant figure out how to do this.
I have spend countless hours on this problem, but I cant find an usable H870 stock rom to flash my phone with.
Is there someone that can help me out with this problem? Im willing to donate some € if someone helps me to get my phone working again.
Really hoping for a kind person to help me out and provide me solution for this issue.
Thanks in advance

Try formating data in TWRP(not factory reset) then flash the 10f complete zip. Trying to perform a factory reset from within Android could have possibly messed up your data (due to TWRP being installed instead of stock recovery) so a full data format is needed.
Lgup most likely doesn't detect the phone because you wiped system. But flashing the complete zip should have restored system.
In the future make backups in TWRP to restore later.. or flash a kdz with lg bridge or lgup without wiping system first.

Thanks for your reply. I have already formatted data in TWRP, but im still having this problem . It seems like something is preventing my device from starting up. I have flashed several ROMS on other devices, but never experienced something like this. Is there something else I can try? Can I flash the stock recovery and flash the stock ROM? I got the feeling TWRP is causing this issue.
If its possible to flash stock recovery, where can I find it?

Flash the complete zip then boot into download mode and flash kdz. Lgup should see the device as a g6 now instead of unknown device. If lgup isn't seeing any device at all (including unknown device) then your setup is off.. missing drivers or something. If that doesn't work.. idk.

Don't factory reset using the in phone option. You can only do this through twrp's option. To fix this you'll need to boot through the hard side, using power and volume down until the lg logo appears then release power for 1 sec and then repress keeping volume down pressed. Confirm yes twice on the white screens to get to twrp. Once in twrp then reset again and reflash the system. Then using twrps img installer flash your twrp img(make sure it is on ext sd) again. Then reboot.

Ohhh F*** YEAHH!!! :victory: Booting the "hard side" fixed the problem!! It was the first thing I tried this morning. I just booted this way and rebooted my phone without resetting or flashing anything. Im so damn happy lol. I still dont understand what happened and why my device was actling like this. But I learned a hard lesson; backup, backup and once again: BACKUP. And dont Factory reset in Android!
Thanks a lot for your help guys! I really apreciate it! :victory::victory:

Probably because you already did all the flashing prior to. Glad it worked. This happened when I first got my V20 and was stoned not thinking. I reset using the in phone option and it caused twrp bootloop. I too learned the hard way.

Had the same issue, fixed it, thanks.

My phone kept doing this booting into recovery no mattery what ROM I installed.
I got into twrp by holding volume down and selecting yes on next 2 white screens....but now this message appears all the time.

Great tip @Swizzle82! It allowed me to restore my LG G6 after bootloop. It had not been detected by PC, and this hardware reset helped!

Hi, all
If I understand, and to sum up :
I rooted my LG-G6 few weeks ago, and intall TWRP. When OTA wants to install official update, the reboot stops in TWRP mod, so ... failed :-/
Is the solution to flash through Uppercut/LGUP with a .kdz file, without risk of brick the phone ?
Thx

Nexus 6p bootloop (NOT same as Infamous BLOD)

Hi! Guys I have a problem, which doesn't resemble the BLOD, so here is what has happened. I was running stock android June build on 6p, rooted. And my phone started random reboots. I thought it could be fixed with either stock or custom rom. So I decided to flash AOSPA. I went into twrp but could not flash it, phone rebooted each time. I tried stock images via flash all command as well as manual. No rom worked although I could flash kernel etc. I used The Flash's custom twrp and fixed data and was able to flash rom easily, but it bootlooped on google logo, and rebooted. Now I can flash roms etc but it bootloops. Although Tesla rom did go into bootanimation before bootlooping.
So what can I do? Is it software related? What do you guys say!
PS. I did look into other threads, nothing was similar, although I did try a few mentioned fixes.

Use fastboot to FORMAT system, userdata and cache. Note any errors during the FORMAT process.... and then try flashing a full image from Google using flash-all.bat

I'd say you were squarely in a small group of people who are able to access and fully use Recovery but still boot loop after formatting and installing a clean image. If you've already tried a factory reset from the stock recovery I think you are done. Hardware issue. Replacing the motherboard is a fix, but not economically viable.

I had the same issue formatting data and cache to Ext4 and flashing modified stock ROM fixed. It would boot to Google logo freeze reboot and sometimes get to boot animation freeze and reboot.

Cortex ROM it's flashable stock firmware with extras . Though my symptoms where the same I hope I'm not giving you false hope. Worth a shot though.

The only was I recover my phone without replacing is using https://forum.xda-developers.com/nexus-6p/general/boot-images-bootloop-t3633723 < method from here... but the phone is lag af as it is only running 1 core on stock july build. Good luck for that.

I have the same issue going on. i was trying to flash magisx and suddenly it is stuck in bootloop. i tried flashing stock images and everything. i can access twrp and flash eveything and they are getting flashed fine but still it is stuck on the bootloop.

So have you used fastboot to FORMAT system, userdata and cache? Did each format command complete with no errors?

How to root on stock 7.1.1 using Magisk

So I installed TWRP recovery using tuliptool and all that, but didn't bother with bootloader unlocking since it said it's not needed. So I tried to install Magisk using the instructions on their thread but after booting it asks me to reset my phone because the data got corrupted.
Luckily I had backed everything up beforehand, so I restored boot image and everything works fine again. Just wanted to know what I did wrong here. Did I miss any steps?

You probably didn't miss anything if it's the "Your device is corrupt. It can’t be trusted and may not work properly” error, I get the same thing. You messed with the files in the boot partition so ZTE's "safety" features in the stock ROM automatically call them corrupted. I simply hit the power button and continue to boot, my device works fine (actually much better than before being rooted with Magisk). I'm the one who "corrupted" the phone on purpose, so I'm comfortable it's fine. If you're getting another message, I'm not entirely sure why. Maybe try ADB sideloading Magisk in TWRP, it's what "worked" for me.

What do you mean by "hitting the power button and continue to boot"? When I hit the power button on the "Decryption unsuccessful" screen it just locks and unlocks like normal, but stays there.

Ok I managed to install Magisk after factory reset, but after that my sdcard is not being recognized anymore (but is recognizable in TWRP). So I decided to restore the backup i had, and rebooted. But now I'm stuck on the ZTE logo during boot. I can still open TWRP, though. I've tried wiping system, data, and cache, then restoring the backup, also no good. For now I'm downloading the stock firmware and will try that. Any ideas on how I can fix this before I flash the stock firmware?
EDIT: Ok I managed to fix it by installing the no verity boot image instead. Boots again. I'll probably refrain from trying to root for now. Thanks for the help.

Well, I wasn't much help, but it sounds like your overall problem was different than mine. My only advice is if you attempt to root with Magisk again, is to connect to your PC/Mac/etc with a cable, use the Advanced menu in TWRP, choose ADB sideload, and sideload Magisk from your PC/Mac/etc. You can find a more advanced explanations on various websites how to use ADB if you don't already know how. For some reason that worked for me and gave me full Magisk and phone functionality when nothing else did.

I didn't have to, but I can't guarantee it will work for you. I had previously factory reset my phone but at the time I sideloaded Magisk I had been using the phone for at least a week. Just make a backup of everything first to be safe. *edit* I am using the beta version of Magisk (16.4), not sure if that's making a difference.
