Why is my TWRP backup of stock EMUI unable to boot? (And what can I do to fix it?)

Whenever I try to return to stock EMUI 5.0.1 from Lineage OS 14.1 with my TWRP backup, it just stays at the boot screen that says "Honor" and doesn't continue past that point. I was wondering why this happens and what I can do to fix this since I want to return back to stock without doing the painful dload method. I currently have TWRP 3.1.1-0 OpenKirin Edition, the same version I used to make the backup too.

Which LineageOS ROM do you have, OpenKirin's or HassanMirza01's..?

Did you already formatted data partition back to ext4 before trying to restore the backup? Hassan's roms are f2fs based, so you won't be able to restore an ext4 based rom over f2fs

Should I do that before restoring the backup? I've done it after restoring the backup, and it doesn't do anything but mess up TWRP's permissions.

It booted up whenever I changed it back to ext4, but it comes up with a screen saying "Unencryption Unsuccessful" whenever I boot up. I click on reset phone, and it brings back to TWRP. This even happens if I reset the phone via TWRP. I'm not sure if this process would work if I restored the stock recovery, but I'm not sure if I want to find out.

Whenever I formatted data through the stock e-Recovery (the stock portion of the recovery that stays even with TWRP), it booted up perfectly fine! Thanks for all your help!

Soft brick after restoring backup with TWRP

Ok... As you can see from this thread,
https://forum.xda-developers.com/on...en-restore-t3804734/post76832485#post76832485
I soft bricked my phone after trying to restore a backup in official TWRP.
I followed this tutorial https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-unlock-bootloader-flash-twrp-t3792643
And jumped over to this tutorial https://forum.xda-developers.com/oneplus-6/how-to/guide-how-to-install-official-twrp-t3801558 per this post in the tutorial https://forum.xda-developers.com/showpost.php?p=76564290&postcount=5 note that this post points to another way of getting TWRP. The link I went to is how to install OFFICIAL TWRP.
And jumped back to the original tutorial for the rest. I'm scared to death now to try and test the restore functionality in TWRP. Has anyone successfully restored a backup? If so, what steps did they take to get the backup and what steps did they take restoring backup? What partitions did the check.mark during backup and what partitions did they check mark during restore? And do you need to do anything with changing the a/b slots????
Edited to add correct link to install official TWRP.

Flash stock ROM in TWRP, flash TWRP again. It won't touch data partition but you can restore just your data partition from your TWRP backup. Boot into system once, then reboot recovery and flash magisk if you want root. All modules you have will be back and active after that.

On the off chance TWRP says there is no OS after flashing stock ROM and TWRP, ignore messages and boot anyway. It will restore your phone without losing all data.

I'll try this and if this works and is in deed the process we need to follow until TWRP can just do what it's supposed to, then shouldn't this stuff be in the tutorials or have the OPs actually pulled this off like it's supposed to be?

I restored boot, system and data and ended in twrp loop. Flashing magisk revived it.

To tell you the truth I didn't even see the other post and was trying to get the renovate magisk module working in the process. It was the first time for me trying to restore a twrp backup because I borked something in the renovate magisk install. Like I said, I tried restoring boot, system and data and ended in a bootloop twrp situation. I figured what the heck, let's try flashing magisk root again and see what happens, and voila it work.

Yes me too twrp on oneplus 6 are buggy when I had restore all system part my Phone enter in bootloop [emoji58]

Ok. Worked like a charm. Thank you so much. I tested all this without any lock screen security. Now I'm wondering if this procedure works with backups with lock screen security.

Ok. Just tried what tdamocles did. But I've been wiping before restore. I then just restore and select system, boot, and data. I did not reflash TWRP. Rebooted and everything was good. Still had root and didn't need to reflash magisk. Was also able to reboot back into TWRP, so there was no need to reflash TWRP. But.... I think that is due to not flashing the stock room first. I'm assuming that if you reflash stock that you will indeed have to reflash TWRP. So, conclusion... If you restore system, boot, and data then no need to reflash TWRP and in my case no need to reflash magisk. Again, this is without lock screen security. My next test will be with lock screen security unless someone posts a negative result before I do.

You will not be able to get past encrption if you decrypt in TWRP and restore. It essentially forgets encryption key.

Just performed a backup with lock screen security and was able to restore the backup choosing system, boot, and data. No reflashing of TWRP or magisk. Not sure if needed but I've been performing basic wipe before all my restores. Still able to boot back into TWRP and still had root.

Nice.

I have restored from twrp a couple times now with no problem.. I did get the message saying can't mount system or something like that, ok I went into the mount options and mounted system after that the restore worked perfectly and I could boot back into the rom and back into twrp after.

Restored mine yesterday too, all files checked when backup, deleted lockscreen settings before, few bootloops at the beginning, until phone changed slot, then booted into system. Cheers!

Not necessary to check all partitions. This only results in a huge nandroid file.

disabled encryption

I have successfully decrypted my essential phone using the dm verity disabler by zackptg. Need to test it some more, but twrp boots after flashing it, instantly.it doesn't have that lag

were u rooted before or not? did u have to format everything in twrp?
edit it actually works!!!!!! I'm unencrypted...i can go into twrp while a pin is set....i can flash magisk with first boot of a rom and it boots...!!!!!

This is a huge advancement. I didn't think it worked until I booted into twrp. And it was instantaneous.so before I flashed the dm verity decryption zip, I did indeed wipe everything on both slots, then mounted system in twrp and flashed the zip, then I flashed the ROM.i will be switching back to stock to test if it stays decrypted later today. I'm running a gsi,(benzo ROM+ all my own customizations)rooted,with all the trimmings) the same mentality will have to follow, but it will be interesting to see how it goes with flashing stock fresh. I imagine restoring my nandroid will be fine and stay decrypted, but probably will have to flash stock, then after setup, back to twrp, wipe factory reset and flash the dm verity decryption zip..I think, I gotta just do it to be sure. Anyone who does this should share notes and that will help the community.
Here is a good question, wtf can I do to have lte again. ever since pie official, I lost lte.phone drops to 3g during calls only. I discovered this while searching for a fix for my volte. Hence,, switching to gsi's because they don't have volte and neither does my stock, even with fresh installs.i have t mobile.all the betas it worked fine.

I have found that after booting up a gsi, factory reset it. Then be sure not to root with magisk. Every time I tried it killed my data and wifi. Use phhhsuperuser ab zip. I think I may have had to flash my modem.img a time as well after the initial install.
And yeah I got it kinda, still no lte. I'm gonna try a modem img from the pie firmware..I think it is the problem

Has anyone had success in decrypting on stock? I cant get it and then i lose touch with the phone booted up. So in other words do not try to decrypt stock. U will wreck your phone and the only way to fix it is to flash stock via fastboot AND adb sideload. One or the other doesnt fix it for some reason. Has to be both.

So these are all the steps I took to get it to work. All of these steps may or may not be necessary. I used aer0zer0's stock dump for the lastest release of oreo and flashed the wipe all bat. It did its thing and wiped and flashed on both slots. I booted into the rom and finished initial setup and enabled adb in developer settings. I rebooted to bootloader and flashed twrp to inactive slot. I booted into recovery and selected the format data option and typed yes. I rebooted to bootloader and reflashed twrp. When I booted into recovery I transferred the stockboot.img, magisk 17.1 zip, and disable encryption zip to the phone. I flashed the stockboot.img to the boot partition. I then flashed the disable encryption zip. I then mounted the system partition and flashed the magisk zip. Finally, I rebooted into the rom and set pin and fingerprint. I installed EX Kernel Manager and created a backup of the decrypted magisked boot.img just in case. I flashed twrp through ex kernel manager and rebooted to recovery. Everything stayed decrypted. I flashed my newly created boot.img backup and booted back to my rom. Thats it. I hope I remembered everything. I hope this helps. Again, I do not know if all the steps I took are required but it worked for me.

Fix infinite boot without resetting data?

Hi,
after installing and uninstalling some Magisk modules, my device (OP6, OOS, blu spark TWRP, Magisk) randomly froze and after restarting, it keeps booting forever. I can still get into TWRP, so I tried a few things to fix this like:
Uninstalling and reinstalling Magisk
Flashing OOS, TWRP and Magisk again
Flashing just OOS,
but nothing seems to help. Is there a proper way of fixing this without wiping my data partition?
If there is not, how do I save as much of my data (like system settings, app data etc.) as possible from TWRP so I can restore it later?
Thanks for your help

I think you might have to wipe if you can't get your phone to boot after dirty flashing ROM. I would try flashing your boot. Img first in case it's magisk related problem. What ROM are you on?

You can backup data in twrp but that might be the reason you can't boot. Google backup should of backed up most things. At this point you should be more concerned about getting your phone to boot.

Cannot boot phone after updating

The problem is kinda complicated. Previously, I flashed a custom ROM on my phone (a modified version of Oxygen OS). Just now, I updated my phone using the official ROM downloaded from Oneplus's official site (no idea what I was thinking), and I was only able to boot into the stock recovery. So, I tried reinstalling the TWRP recovery. I was able to boot the phone, but upon boot, it would say something like "Settings stopped working" and it would shut down immediately. I tried flashing a couple of different ROMs using the Install option in TWRP, but I still get the same error when booting my phone. Is there anyway to solve this problem? If not, would there be any way for me to recover my files at least?

Go back to factory stock using the MSM tool. If you can get to TWRP you can backup your stuff.

I am able to get to TWRP right now. However, I did noticed that the Data partition in the TWRP Backup option is only 76MB. Does this mean that my data's gone already somehow?
