Develop Bugs

[Help] Firmware is broken after reboot.

Hello,
I have a weird problem with my phone. Few days ago I've drained my battery and swapped it to the fresh one. But after phone booted up everything is broken.
My wallpaper changed to the one i don't know, it even doesn't look like stock one (Screenshot 1).
Notifications doesn't show up. Probably because upper drawer doesn't work now as well (i can slide it down only once, to show me date. But can't slide it down further to change sound profile, wi-fi etc. Screenshot 2).
Home button doesn't work, square button (the one for switching between applications) doesn't work either.
Half of the settings got reset to factory, some of them stayed unchanged but doesn't work anymore. For example, I've had my lock screen protected by pin. It still shows in the settings that I've set pin code, but there is no actual pin lock when I'm locking my phone (Screenshot 3).
Developer options menu says that they "are not available for this user" (Screenshot 4).
Even my QuickCircle case doesn't work anymore.
I have F400L one with Fulmics ROM 7.6 (6.0 Android).
I've tried to dirty flash it (i was on Fulmics 7.5 before). But after flashing new version of ROM everything still the same.
I've tried to wipe Dalvik + Cache, no luck either.
I don't want to do a full wipe, it will be a huge pain it the ass to reinstall and reconfigure all of my apps. Especially ones like Google Authenticator.
Dear community, do you have any suggestions what happened and how i may fix it?
UPDATE:
Found same problem: https://plus.google.com/u/0/+PaulOBrien/posts/8EGNvpY9jQa
Solution is to type this command (through adb or terminal):
am start -n com.google.android.setupwizard/.SetupWizardTestActivity
At this moment, this command resolved probably all of issues occured.

Gen 1 firestick Non-rooted, boots white amazon logo for 5 mins then works... sort of

...and FACTORY RESET fails
Hi all,
We have a gen 1 firestick - I did have Kodi installed but NO ADDONS we just used it as for playing home media and photos from the NAS etc. so just Kodi ITV player, youtube via firefox, etc etc. Amazon Prime...
All was fine until a few days ago when I noticed things not working right. It failed to install an ITV hub download and Kodi stopped.
When trying to install an app, it said downloading and then came up with an error such as this:
best picture hosting
It's been installed a while so I thought I would factory reset it.
I did the reset through the menus. It had the reset message on screen for a few minutes then went to black screen. So after 1/2 hour I cycled the power. The white amazon logo came up and then I get the account login screen after 5-10 minutes. I have to then pair the remote - but this won't work unless I take the (brand new duracell) batteries out of the remote for 10s then hold home to force the pair.
The firestick then automatically logs in to my router (though I haven't given any passwords etc.)
I set up the account as normal and I can use BBC iPlayer for example and all seems fine but any app I try and install just fails to install - it gets to the 'downloading icon' then says that the download failed.
If I cycle the power it goes back to the 10 mins white logo and setting up the account all over again.
I tried a second network and a different amazon account and it's the same.
Tried lots of factory resets but always the same outcome.
I do notice that the stick reports 3.19GB of memory used !
I suspect that somehow some files are corrupted on the stick and something is stopping it from doing a proper factory reset so I thought (from reflashing phones in the past) I would try and boot into recovery and try and to a reset from there instead.
I can adb to it,
I managed to boot to recovery but it just gives me a load of this failed and that failed messages at the bottom of the screen.
Any suggestions of how I could force a proper reset or what might be going on would be very gratefully received.
Thanks in advance ?

black screen loop on initial configuration

hey guys, I have a problem with the mi a2 lite. After having sbricked and installed 10.0.9.0, in the initial configuration, if I select something, the screen opens and after a second the screen goes black, remains black for 5-6 seconds and then returns to the initial configuration screen (the one with the word "Hi there" where the language is selected.
What can I do?
The last time it happened to me was when I downgraded to 10.0.3.0 (same symptoms, the screen went black and left black for 5-6 sec), I tried to reinstall the 10.0.3.0 from fastboot and the phone got bricked, I had to enter edl to fix it

I made a video if it can help

How do I reset the phone? Thanks

Motorola One Action auto update failed now stuck on "Just a sec..."

Hi,
My Motorola One Action is original (so no custom firmware or rooted) and every now and then i receive auto updates. Recently the phone was upgraded to Android 11. Fine.
Last weekend there was an update and in the morning the phone was stuck on Android bootloader with the question "format" or "retry" (cannot remember exactly, but it was 2 questions) and i chose "retry". The device rebooted; android logo showed up and then the google/android assistant showed up with the notification "Hello" and a lanuage selector.
I choose NL or EN and then a white screen with "Just a sec..." appears and this screen will stay there forever. I put the phone on charger and waited 30 hours, still the same.
What i tried:
- reboot;
- press & hold power button long time; reboot;
- turn off and then volume Down + Power key bootloader. There isnt much i can do here;
- from screen above; go to fastboot mode (volume Up + power) but unfortunately there is no whipe cache option; only whipe data / factory reset.
FYI: there are still a lot of photo's on the device; i dont want a factory reset and/or whipe data.
I put device in bootloader mode again, connect with usb and installed "Rescue and Smart Assistant". The device recognized, IMEI is found and more stuff. In this Windows app i can download the correct firmware; i store it in c:/motorola/firware. The file is troika_reteu_rsbs31.q1-48-36-23-2_subsidy-default_regulatory-default_cfc.xml.zip
The the "Start Rescue" button is shown; but the message "Flashing removes all data from device".
I dont want that so i followed this guide:
The conversion went OK and executed the file generated (.bat), immediately a upload process starts; this takes about 5-6 minutes. After that; a device reboot and still... the same result.
Any tips or advice would be very helpful (i hope).

I found this; looks promising

But unfortunately the image browser does not respond.

I have contacted Motorola / Lenovo using their forum. In short their answer is that for almost sure the only way is to completely reset the device that means whiping data.
Is there absolutely no way to access the data partition?

I used ADB to flash a newer and older version of android.
Both version gave a error message directly when phone powered on.
Then i re-installed the current version of android; phone worked again. Unfortunately all data lost.
