Mate 8 L29 after backup: settings, camera, etc. won't open. - Mate 8 Q&A, Help & Troubleshooting

Hi, i have a problem with Mate 8. I was using [K-Rom M8-V5]. Before installing it i did backup of everything(of a stock ROM), and SECOND backup after installing K-Rom and apps like Facebook,Youtube, etc.
I installed some bad module for xposed, and had bootloop. So i restored the second backup but when device booted NFC enables and disables automatically, camera won't work, keyboard, settings menu etc. Chrome etc. works fine or stock games, but keyboard, settings menu, camera not.
I restored first backup(this before K-Rom), NFC stopped flashing, but camera, keyboard etc. won't work. I found rollback from 7.0 to 6.0 here:
https://forum.xda-developers.com/mate-8/help/looking-downgrade-package-europe-model-t3528574.
But when i install rollback package it stops at 5% and says: "Software install failed" "The update package does not exist." "Please download the package again".
Could someone help me step by step how to configure android so keyboard, camera, settings menu etc. will work again?

Restored many backups, boot images. Managed to enter the settings etc. But still cant enter to programmer mode, fingerprint, playstore etc. doesn't work.

Restored everything by myself step by step. Found right stock recovery. Rollback to 6.0 everything is fine. Delete/Close thread.

[Q][SOLVED] Help! Suddenly stuck in Bootloop (after deinstalling/disabling Launcher)!

Hi there guys,
i have a big problem with my OPO.
First, i explain what i did: I'm using my OPO also in my car, so i set up a home launcher that's "car friendly" (big buttons, big clock, car logo, and so on). To activate this Launcher i use Tasker with root permissions. There's a Tasker-Task-Shortcut on my normal Homescreen, and when i press it, some things are switched off/on (for example GPS is switched on and the brightness is set to high). Also i switch the two Launcher (Default and Nova Launcher) by setting the Package State of the Default one to disabled and the Nova Launcher to enabled. If i want to go back to normal mode i press the Tasker-Task-Shortcut on Nova-Launcher which reverts all settings, including chaning the package states of the launchers again. This worked for years now, but today i activated the car mode and Tasker asked for root permissions. I thought SuperSu made an Update so i need to accept it again, so i gave Tasker root access. After that the Default Launcher was disabled, but the Nova-Launcher wasn't enabled. Then there was an empty screen, i only saw the top Notification Bar and the Soft Buttons (It was possible to use both), but no Launcher was loaded. So i restartet my OPO and now i'm stuck in a Bootloop...
Can someone help me please?? I think a factory reset will fix this, but i dont want to lose all of my apps and settings! What can i do? Is it possible to change the package state trough Fastboot, or through TWRP? Fastboot and the Stock Recovery is working fine, only if i want to start my OPO normally i get a bootloop... Maybe it's possible to install another Launcher via TWRP?
Please help me!!
Greetings,

Install another launcher via desktop play store then when click home button it ask for new launcher
You mean i going to play.google.com, search for another Launcher, press install, and select my OPO? If yes, that wont work, because i cant start my OPO (stuck in boot). So the OPO Play Store cant install that launcher. The only way i can think of is to install an alternate launcher through recovery.
EDIT:
Update, i used TWRP to clear the cache and dalvik_cache and now my phone is starting. Then after the "Configuring Apps" screen it's now stuck on "Starting Apps...".
Phew... fixed it myself... to anyone with the same Problem, here's what i did:
Search for a flashable zip of an alternate Home Launcher, for exmaple "APEX Launcher". Then go to fastboot mode and startup TWRP (i used OPO Toolkit). In TWRP, activate MTP and push the flashable zip to your phone. Then install it trough TWRP and clear cache and dalvik. After that restart your phone and the new Launcher should start. From now on you can switch to your default Launcher again.
Greetings

Issue with TWRP and Root

since upgrading firmware from b3++ to b571 i am facing this issues
1. google translate cannot instal the downloaded language.
2. root and unroot still left leftovers which hindering some of the apk wont run even with rootcloak
3. full twrp still leave missing symlink
so i have been experimenting what are the cause, twrp or rooting
1. google translate the issue is twrp ( not sure why) even if i restore to stock bootloader, translate will not be able to install the language file.
2. rooting and unrooting will still left traces which the apk still able to trace some of the su file. rootcloack wont work with some of the apk
so the only solution is to restore the whole firmware from scratch.
my question, is anyone manage to reslove this? . i want to root and restore few things like the data/network at status bar and hide/unhide the navigation bar. the unroot back cause i need some apk that don like root like banking apk
For what it is worth; I flashed the recovery backup over 51 and did a factory reset and flashed supersu for root.
- I used translate a week ago and was able to download language package
- I am able to watch TV with an app which is denied on rooted devices, maybe you could try adjusting some supersu boot settings as it works fine for me
- Data/network settings are stored in the Google cloud and auto restored?
- I use Nova launcher which allows navigationbar hiding. I bet it should be easy to enable.
Since restoring apps is not much a deal as you can choose all apps you want to restore in Appstore by using longpressing an owned app in your person overview.
The only downside may be needing to reconfigure some apps but I suppose you could restore those be need.
Which TWRP have you installed?

Weird App behaviour after upgrade to 11

Hello
Info:
Updated recently to 11 using full factory image with wipe (with - w flag).
Rooted with Magisk (canary update channel, see images)
Patched clean boot file and flashed with fastboot flash boot magisk_patched.img
All good.
Problem: trying to open a .docx file from storage with M$ Word. Screen goes black and phone restarts. On first restart I get the dreaded "cannot load android system - try again or factory reset. Luckily try again does boot my phone.
Attempted solution: remove and reinstall word - click uninstall -" the app wasn't found in the list of installed apps" - see image.
Went to play store to reinstall - only have "open" button - when clicked, screen goes black and back to "cannot load android system" screen ?
Any ideas/advice much appreciated
Many thanks
*Update*
Couldn't resolve via normal methods -
Used App Inspector (UBQSoft) from playstore to see if M$ Word showed up in there and it did:
From there, clicked the cog wheel to go through to "App Info" screen and was able to successfully uninstall from there.
Installed the Office full suite as a work around and am now able to open the document as needed.
Any thoughts or info still appreciate - especially if anyone has had a similar bug, even with different apps.
Many thanks ?
Further Update
So, I've gone back to the same document about an hour after being able to open it - same prob, screen goes black, phone restarts to "cannot load android system - try again or factory reset"
Tried open again from within Files,
got message "none of you apps can open this file"
I have office installed - see images.
I think I'm going to go back to Android 10 - this is quite the inconvenience for the time being
Not sure if it's 11, Magisk or kernel (using the latest EXKM)
but it's system UI that keeps crashing - I cleared out storage and cache as I am currently unable to uninstall Office, even via App Inspector.
*Solved*
Removed one of my Outlook/Micro$oft accounts to which Word and Office were both previously syncing - removed Office via playstore Uninstall button and rebooted phone.
Tested opening the same document both from Files, SolidExplorer and from within Word, opens for editing no probs and performs as expected.
Root and EXKM still installed and fine.
Sorry for multiple updates, just thought it might be useful for anyobe with similar issues.

HELP After updating Android System Webview My Phone is Unresponsive

Hello Guys,
I come in need of a help,
I'm writing from my computer now,
Yesterday my phone was working fine,
Today morning, I updated the apps on my phone; amongst the updates was android system webview.
After a reboot, my phone is unresponsive, it won't open any of the apps from that point.
I reboot again, since keyboard doesn't work, I used the OTG cable to use the physical keyboard to enter the password and get in. Tried entering setting to uninstall that crap app, settings is unresponsive.
No SIM services, no keyboard, no fingerprint, no settings etc.. basically nothing works and everything says "unresponsive and asks to either wait or close".
The only thing I have now is TWRP Recovery, and I'm inside it now.
I've wiped Cache + Dalvik / ART Cache : Result still same, nothing works.
I mailed [email protected] (which is provided in the app's "Developer" section) about this and got a reply that the mail is no longer being monitored.
Can someone please let me know how I can remove android system webview by using TWRP ? So that I can enter the phone back again as normal..
Device Details:
Lenovo K8 Note
Android 7.1.1 Nougat, (Never updated the OS)
Device has been rooted and has recovery options.
I think you can find WebView module in Magisk respiratory so I suggest you give that a try. Flash it and I think it will be fine as long as you have Magisk installed, of course.

Thanks, I couldn't quite understand that..
I've never read/seen a need for Magisk so far.. so may I know what is the procedure to be done here...?
I do read Magisk is a systemless Root, (I already have SuperSu, is that the same functionality? (though I can't open anything that is))
Find the Magisk zip on Google and flash it over TWRP.
Head over to the Magisk module site and you will be able to find an alternate WebView module you can flash. It will be in zip format so I guess you will need USB to transfer those files to your phone since you cannot use it to download modules.

Give it a try and come to tell if you have sorted it out.
If not, you will probably need to flash your ROM again hoping the application won't stay updated but to back to stock version.

Oh, one more thing,
Does this procedure mean, I'll lose TWRP and SuperSu?
Can I not just downgrade the android system webview manually itself?

You won't lose TWRP but I am not sure about SuperSu since it's very old and people don't use it from the time Magisk appeared. I don't think you will be able to have both TWRP and SuperSu.
It would be good for you to just uninstall the updates of WebView if you can use your phone at all. That would solve the problem.
TWRP basically is a menu what allows you to select and apply ADB and/or Fastboot commands.
SuperSU is a Superuser access management tool: it requires SU binary got installed on Android.
Both mentioned sofwares are completely different things, don't depend on each other.
BTW:
I always root Android without the need to make use of Magisk or SuperSU.
So, I went through these

I got is, .. the adb and appt command says "not found". so.. confusion. and I also see that Bromite System Webview might or might not work on some apps..
So,
Is there a way to downgrade an app through recovery mode
or delete that app's data and start from scratch for that alone?
or is there a way to flash an old Android System Web View through TWRP?
Please help, I have spent the whole day trying to fix this.
I already have SuperSu and it seems if I need to goto Magisk (which is just for that other webview application, I have to do a lot of rolling back and applications going away, ) I don't want that..
Let's keep the Magisk idea as last resort and please let me know if there is any other way to delete the entire Android Webview related stuff and start from beginning.

Attached the attack of errors. (these are just few of the ANR popups, there are lots more.. at the last screen you can see even settings won't respond)
My recommendation: Reflash phone's Stock ROM to get rid off of all modifications you applied so far, then restart modding from the scratch.

Just because of one application?
I just want that android webview gone/replaced with a stable one, is that not possible without destroying everything?
Thanks everyone.
we have a solution,
In my case, uninstalling the Xposed framework fixed it for me..
So, while working on this issue I had made a flow map and a log of what is done and its results, may be someone else can benefit from it in the future..
Spoiler: Tries and results
Even starting the entering phone itself is a big issue, because the keyboard applications don't come up; fingerprint doesn't work on first boot as a security measure as well; connected physical keyboard to OTG to phone to enter password... then greeted with lots of errors of all the applications.

Posted to Reddit, no replies
Posted to Google support, got crappy bot_ish answers; who even hires these people!
Posted to XDA, have some ideas worth trying
Unpacking the system web view.apk on computer gives crap details as it is almost completely encrypted.
Going rabbit hunting through the rabbit hole, checking each folders on "/"
found something similar /system/app/WebViewGoogle/WebViewGoogle.apk
Quick google search confirms that I’m on the right path to finding it...
May be data or XML is somewhere too?
Deleted(copied and deleted) /system/app/WebViewGoogle/WebViewGoogle.apk
Result, Same
Then Reverted
PS: Original Copy at ext_sdcard
Replaced the existing one (92.0.4515.115 with 90.0.4430.210)
Result, no changes.
Then reverted with the crappy original
May be adb will install properly?
Tried adb commands on phone on TWRP, doesn't work
Tried adb from computer to phone, unable to connect to phone.
Was doing it wrong, while in TWRP, I need to initiate "ADB Sideload" and then connect from PC (with Firewall allowed)
then "adb devices", shows connected device with serial number
after the above, the adb push keeps saying "error: connect failed: closed"
turning phone ON and connecting for additional settings (USB debugging) pops "mtp host failed" as soon as I wire..
Started the phone, switched over to Guest account, (oddly seems stuff there are kind of better with lesser error messages), tried launching playstore and wifi, both need password which I don't have, entering settings, hangs for a while, quickly go to apps and uninstall updates for android system web view.. web view becomes 0.0.1
results, fail
Created a temporary user account on phone whilst booting, (because of the observable lesser apps running if I switch over from main..)
added my gaccount on it,
launched playstore to update the android system web view..
the update is stuck at 60%~70 %each time and is unable to complete..
took the v90 application that is on pendrive, connected otg.. and started to install application manually from there..
it said, no space.. even though there is around 4 GB free... continued to disable other applications, such as chrome, youtube, drive etc..
still unable to install the v90 application
even installing other apps (sudoku example) have the same issue,
and then I see a popup that package manager has stopped working (aha! so that itself doesn't work, then can't install),
Went to see if I can change something on developer options, developer option wont come up even after 7+ taps.. hmm strange, may be only main account can have dev options.
While at it, swapped out the Gboard with older AOSP keyboard (retaining Fleksy though).
Rebooted and tried again.. no fix yet..
Atleast I don't have to switch to physical keyboard now for every reboot, since the inner older keyboard comes for first boot.
By TWRP, removed existing app and replaced with v87; doesn't seem to be any different, same errors...
Was about to install the Magisk but it seems to have lots and lots of catches to it, and things to-do before I can go to that...
Continuing investigation on how to downgrade and get back to older state
Through TWRP, deleted the app folder from /system/app/WebViewGoogle/WebViewGoogle.apk
researched to see if there is something else to delete, couldn't find much... proceeding from what we know...
Removed ATSystem.apk (3C's helper) from /system/priv-app just in cast (copy placed at ext_sdcard)
result no change..
Started at around 31-Jul-21 13:00 and went on till 01-Aug-21 01-26 pausing to for the day to rest...
Restored App Folder back to /system/app/WebViewGoogle/WebViewGoogle.apk
WebViewGoogle.apk is v90 again.. (the original seems to be missing, meh, not like it's going to fix)
reboot, result, no changes.
Starting step to install magisk
Removing xposed now..
wiped dalvik cache
rebooting
Kind of stable!!!
Everything seems to work?!?!
Firewalled all app except playstore and mail,
mail seems to work, but can't open the mails (just the headers are received), clicking on the mail says "unable to inflate webview"
aha, I forgot that I have v87 still, if I update that again, will it work (if it doesn't we know how to revert now)
proceeds to update v87 to latest
reboots,
I guess issue resolved by uninstalling xposed, next step to enter phone and move data to safe zone and think about next step.

Oh... sorry to hear that.
I don't know the solution to that, because mine is rooted I was able to get into the custom recovery and fix things.. not sure what can be done here for your case, (I do know that the old samsung's default recovery is kinda unreadable for English speakers)
So, I think it's best for you to start a new thread in the forum, because if you make a new thread there's a higher chance of reply than this thread which is already marked solved.
(plus. please do attach any photos even crude it may be, still will help people see and suggest actions)

Cannot download updates, why?

Found 12.5.3, tried to download and update, stuck at `get info 0%' forever.
Found package installer system app update as well, tried to download, failed instantly.
Poco x3 NFC, EU version, no root, all standard apps.
The system app update history shows last successful update was on 29 Oct. On 3rd Nov, got the reminder of new miui ota. Then, spotted this bug.
Any solution?
Does the phone work? If have this problem also, but the phone can not write to the internal+external storage at all after the last update, so I can not download anything.
Nevertheless, you can download the official rom as recovery image on your own at mi.com/global => mi community => rom downloads => poco x3 nfc. Follow the flash instructions there (copy file to phone, select it in the update preferences section 'about phone=>miuiVersion') In the case you doesn't have the menu point to select the rom package as file. you have to tab multiple times on the miui logo in the update app to enable this menu point.

thanks mate.
it worked properly except this 'cannot download ' update problem.
Interestingly, the google play updates, camera, chrome browser download, xiaomi music plaer... all write files fine. no problem at all.
the apps that has the problem are:
1. xiaomi's getapp app
2. system app updater
3. the miui updater
i found somewhere the OTA zip and recovery zip. what's the difference between them?
if I download the from (recovery zip) where you mentioned, should I:
1. unlock the bootloader?
2. will the process you mentioned clear all my data after the installation?
Thank you so much. I am awaiting some confirmations before proceeding.
OTA is 'over the air' update, this is also a recovery image. There exists also fastboot images, but these are a different thing.
Make sure that you really download the right rom for your phone (look at the exact type number, e.g. RJGEUXM for European phones, look in the 'about phone' section what type yours is), also directly from xiaomi, as I mentioned. If you use these roms, you don't have to unlock the bootloader, and you also will not loose data. If you select them in the updater, it is just as you receive an OTA update. You have to unlock if you flash with adb/fastboot, but in this case you would loose your data during unlocking
