I'm not sure how to fix... - OnePlus 6T Questions & Answers

So I was trying to wipe dalvik/cache via Twrp, I accidentally did a factory reset instead. After going through the prompt process of resetting up the phone, I rebooted into twrp and restored my most recent backup. No, no matter what I try the phone wont go past the circular boot screen. How can I get past this

Did you try reflashing TWRP and then Magisk?

No, I did not! I didnt have my laptop with me and I was so flustered i hadn't considered it this morning. I'll get back to you after I try it ?
Ok, gave that a try and still didnt work. I'm downloading the latest software update to see if that'll make a difference.

So I flashed the latest 9.0.12 software, and the phone booted. It seems all I need to do is reflash twrp and Magisk and I should be good. Thanks for your input, I appreciate the input.

[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?

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.

Boot Loop

I was having freezing issues with Super User, so tried to uninstall and re-install. When I rebooted the phone it now keeps re-booting? I went into TWRP and tried to do a factory reset, but still boot loops?

Bootloops when flashing System, Data

It first started this morning when my phone suddenly started rebooting while I was using it. Then I thought it as a ROM issue and flashed a new ROM over it. Everytime I try to flash something on system. TWRP Hangs and the phone restarts itself.
Tried repairing data, system partitions from TWRP, same thing happens. Bootloops when I try to repair data partition
Tried restoring nandroid backup. When it says flashing data, TWRP freezes and the phone starts bootlooping.
Can anyone help?
I have tried doing the EFS flash via adb from PC.

Have you tried Claiming Warranty?
try doing a re flash of recovery, because your issue will be to get your recovery working properly or else you cant remount anything else.

I flashed TWRP 3.0.2,3.0.2-2,3.0.2-3
Loads of it. Tried doing full stock + unroot from Nexus toolkit. That usually fixed all my problems Everytime I was in dire problems like this.

I've never used that toolkit. Since day 1, ive used skipsoft android toolkit. just keep on trying. Does it crash at all when doing backups?

Well in your case what I would do is a backup,
Then wipe, flash custom rom. Use phone til reboot.
If reboot, flash stock IMG. Use till reboot
If still rebooting, then come back. I guess I never asked.what rom.your using

It bootloops
I have the exact same problem. Last week upgraded to 7.0, root, stock room, viper4arise audio and EX kernel and that's it. while taking pictures it froze then that boot loop, somehow I managed through a combination of flashing factory image through fastboot, locking, unlocking, reflahsing, to get it to boot normally, then yesterday I was taking pictures again and it refroze then bootloops. Now I am able to fastboot factory images but it doesn't get me out of the bootloops, and in TRWP same as you, I cannot flash anything on data or system. Repairing the file system doesn'T change anything, I did like on other threads also and flashed factury, restored nandroid then flash factory but the restore on TRWP always hangs up.
I was wondering if there is someone knowing the adb dd commands to impose the raw copying back of the restore ? Maybe that would work.
Did you try wiping system under wipe > advanced in TWRP?
In twrp, can you open a terminal and check the results of this (basically, doing a full read-only test of your flash)
Code:
dd if=/dev/block/mmcblk0 of=/dev/null

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.
