com.android.systemui has stopped

I get the following error:
Unfortunately the process com.android.systemui has stopped
The error just keeps repeating if I press OK.
What I did to get this error was:
Backup current ROM using TWRP
Flash a Lollipop ROM (that didn't work)
Restore my backup
and now I'm screwed
I've read somewhere about Italians having this issue and that it had to do with low battery level. I have now recharged my phone to 95% but still no dice And my phone is running US English (though I'm in Denmark).
I'm running CM11 M11.
Can anyone help?

Clean flash.

And how would I do that if I cannot transfer zip files to my phone?
And would I be able to restore my backup afterwards?

You didn't say anything about not being able to transfer zips to your phone, but I'm assuming you mean while booted into Android because of the persistent error. TWRP 2.8.x has MTP enabled so if you connect your phone to your PC while booted into that recovery you can copy a zip across to flash. And no, you can't restore your backup afterwards, the whole point of a clean flash is that it's a clean flash, completely fresh. Plus, restoring a backup after flashing a ROM would overwrite the ROM you just flashed, making it a pointless exercise. Plus, the backup that you have is obviously corrupt and that's what's causing your problem.
In short: download a ROM zip (and gapps), flash the latest TWRP to your phone (if you don't already have it), copy the zips to your phone, perform a full wipe (system, data, cache, dalvik cache), flash the ROM + gapps, reboot and start fresh.

The only backup you should be restoring using TiBu after flashing a ROM are user apps, and certainly not system apps. Restoring system apps will cause problems in 99.9% of all cases.

I'm kind of thinking that it's my TWRP that has some issue. I've tried restoring 3 or 4 different backups and they all come up with the same error.
I'll update my TWRP when I get home and hopefully get a bit further...

He's talking about a nandroid backup, not a TiBu backup.

I know, just talking about restoring backups in general after flashing a ROM.
Hence why I said "The only backup you should be restoring..."
EDIT* misread the OP. My posts were indeed a bit out of context...

Did a clean install - no dice
Then did an install without gapps and then I get to the initial setup where I have to choose language. And then it reboots - over and over. It completely bypasses any indication that there is a SIM card in the phone.
When trying to restore my previous backups I also go straight to my home screen bypassing SIM unlock and phone unlock.
Any other suggestions?

Nope. But I'm going to now Stay tuned...
Well... it's a different bootanim than CM11 - first indication that something has happened
But then Reboot from the language selection screen

Not necessarily. Do you have any signal whatsoever? Can you navigate to Settings/About Phone and see your IMEI? Don't post it here but let me know if it's still showing up.
Transmitted via Bacon

Hmm, sounds like a hardware issue to me if you can't even get passed the welcome setup without your phone rebooting... Especially after a FULL factory reset.
Does the reboot start as soon as you touch the screen? This might indicate some kind of malfunction between hardware and drivers.
Raise a ticket on the OnePlus website and request for an RMA. You might also want to file a Paypal claim to speed things up.

I can't navigate as I'm blocked by the error message. I do know my IMEI from my Google dashboard though.
I'm still puzzled by the fact that it doesn't recognize my SIM card at all.
Okay - breakthrough: I downloaded the package from this post: http://forum.xda-developers.com/oneplus-one/general/tool-oneplus-one-return-to-stock-t2970390
Ran all 3 ONEPLUS ONE - x.bat and now it has prompted me to unlock my sim card. Got through to wifi so I have higher hopes this time around Will see how it goes...

Whether you know your IMEI or not isn't the point, it's whether it's still present on your device that matters. There have been cases where the IMEI simply disappears (along with your baseband) and having no signal is a consequence of that. I hope you made a backup of your EFS at some point because it's looking like this is what's happened.

Be careful, I firmly believe it's a backup that caused this problem, and you might not be so lucky next time. I'd seriously suggest just clean flashing now or you could be inviting the devil to your doorstep.

i dont have experience with your specific device, but yes, it almost as simple as that. thats part of the purpose of twrp is to flash stuff.
the very first thing you want to do is, go to the backup tab and backup all the options.
then, leave that backup on your phone, but save a copy to your pc, for safe keeping, in case you accidentally delete the one on the phone.
after that go to the wipe/advanced tab
note- this step will wipe your data and is manditory, if you have any data you dont want to loose, stop now and back it up before proceeding
select cache, dalvic cache, system, and data ONLY, then swipe to wipe
next go back to home screen and select install, find your rom, select it, and swipe to install
next, reboot and wait for it to boot up.
if for whatever reason it wont boot or is broken,
go back in twrp and wipe the same things as above
then go to the restore tab, and restore the backup you made earlier
then reboot, and it should be back to the way it was.
this will have your phone working while you figure out why the rom didnt work.

How can I see IF the change is made?
Now I can see that the kernel is somthing else.

Unable to Wipe Data since CM13

Hey ! First of all excuse my english I'll do my best.
I flashed CM13 to test it. To do that I flashed the TWRP you can find in CM's thread and just after I wiped the data because without that you're unable to wipe cache/dalvik/system. After the flash everything was right except for some reasons in my opinion this rom wasn't smooth enough so I wanted to go back to EMUI (damn EMUI never thought i could want to go back to this again).
To do that I flashed The "normal" TWRP and tryed to wipe my data. It was impossible. Si I tryed to restore my nandroid, impossible too. Some errors messages.
So I flashed the CM's TWRP and was finally able to wipe my data and restore my EMUI nandroid. After that I tryed to flash again the "normal" TWRP and take a look at the wipe options to see if I was able to wipe data or dalvik or whatever but the same errors messages came to my face.
Is there a way to fix the wipe of my TWRP without rollback to stock and root again ?
I hope I was clear, my english really sucks.
Thank you guys.

seams he's not good enough to get that so I'll explain more !
for some reason or flashing roms u' might get some errors while flashing roms or trying to wipe data ! ..
restoring ur nandroid sometimes need to be restored throw the same recovery but for some binary errors while restoring or for some reason it wont !
I recommended to do the following :
Use the full restoration method to get back into stock fresh . ( to do that all u need is : download fresh rom from official EMUI website then send it to SD card , put it into ur phone , make sure its off , press volume Up+Down+Power for 3 seconds or 4 then will start getting back ur original Software ) if u got fail might be for some reason of a kernel so u'll need to do the ADB Method will be later if fail only .
now after getting back to stock install TWRP again and make nandroid restore only for data without system and cach and delvik
u must get all ur phone back as will but the restoration should be only above same rom version and custom number .
GD Luck ..

Thank you for the "not good enough" man I'm flashing roms since 2009, I had a lot of phones and a lot of way to flash roms. My english sucks, not me.
I know how to erase the recovery but I already try to flash different recovery, it's obvious for me that my problem is here because of the encryption missing of the DATA partition who have been erase by the CM's TWRP. I try to find a way to fix the encryption without get back to stock because it's a pain in my ass and if I can do another way I'll be happy. I hate come back to stock, it's a waste of time to come back to all tweaks I made on my actual rom.
But if I have to come back to stock I'll do it.
I'm use to work with phones more open than Honor so I'm a little disapointed about all the pain devs have with this phone.
Thanks for your help anyway. Oh and yes, I can be wrong about encryption but I don't think so.
Much love.

Verizon Pixel stuck in bootloop. Please help.

Hey guys. I really messed up. I was running 7.1 from launch, and have had the systemless root basically since the beginning. I attempted to mount /system as /r/rw (for the stupidest reason) and my phone booted into a "no command" bootloop. Is there any hope for me? I can access recovery (I think). I can get into adb and fastboot and get the device recognized by the computer.
I will donate, buy coffee, anything for some love. Thank you so much for your time!

Thank you so much for the reply. I think I could even do a factory reset from recovery, but I'm not sure. I'm pretty new at this. I was really hoping there may be a way I could backup my data first, or even fix the issue, as I'm pretty sure I know what happened. I think my permissions are set wrong, but I could be entirely wrong. I found this guide that sounds like my issue, but it is for a different device. I've tried adapting it to the best of my ability, but I can't get the phone in ADB mode from recovery. http://www.gizbeat.com/2103/how-to-change-file-permissions-through-adb/

Wouldn't hurt to try knowing you can also just flash stock images.

Sorry, I was unclear, that was my fault. I believe I know how to flash stock images. That is something I have done since the OG Droid. I was asking if you may know anyone who may be able to help me attempt to backup my data, reset my permissions, or even get the phone into ADB mode before I resort to losing everything. Again, apologies for being unclear.

No worries. I would just look online and possibly post another thread here or just wait for replies.

Flash the stock image but remove the -w from the script to keep from losing data. Search around here for instructions. It's been described a zillion times.

I suppose one could think of it that way but it really isn't. Everything other than data will be wiped and flashed. It'll all be new with the exception of your data partition. Removing the w allows you to keep all your apps and their settings in tact. The rest will all be new though. It can't hurt to try it. If it doesn't fix your problem (which it should) you can always run it again and wipe data along with everything else.

Yes. But in reality it is not much different than taking an OTA. That never wipes data. I only clean flash if I am having issues after a dirty flash and I can't remember the last time that happened.

Yeah, sure. But this is a different case. This is a major update, not to mention it's a beta. Anyway, you could try wiping your cache partition first. You can do that on recovery mode. This won't wipe your data.
If it doesn't work, I don't know any other solution to fix your device while keeping data. If you're ready to let go of your data, the easiest way to surely recover is using MSM Download Tool.
EDIT: I just remembered there's no cache partition anymore. You'll need to wipe cache AND data. I can't check the stock recovery because I'm on TWRP myself.

As a last resort before wiping try changing the active partition from fastboot:
fastboot --set-active=a
fastboot --set-active=b
Good luck.

your chances of keeping your data without a backup recovering from a bootloop is very slim. the simplest solution would be to wipe your data and cache from the stock recovery. If that doesn't work, you might have to go towards using the msm download tool to unbrick your oneplus 6. Here's the link to the thread with the msm download tool: https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109
Edit: Shoutout to r/xdacirclejerk for making me see this

Were you full stock or rooted? Were you using Swift installer?
