[Completed] Lenovo s820 problem - XDA Assist

hi guys ,
This is my first post in XDA. So please inform me if anything is wrong
I have a LENOVO s820 with android 4.4.2
This is the situation -
I rooted my phone. It worked perfectly fine .i installed many rooted apps and so on .i was into taking risk and i installed Xposed. Even it worked fine .Later ,i tried to update the busybox from busybox installer app from playstore. But then i by mistakely took advanced install .So i thought that would harm my device and i thought of uninstalling busybox and installing it again (just to make sure nothing happened after the advanced install) .They showed the warning message "its an advanced option , do you want to continue " , i didn't mind it and i pressed continue .Then i pressed install busybox (as i told earlier that i needed to reinstall busybox ). This was the time my phone did not work as expected .The busybox installer force closed everytime i opened. I installed many another busybox installer but none of them didn't work
Then to get things right , i did the following things-
1. I tried to unroot my phone (with Kingoroot) , it didnt work
2.I tried to unroot it with supersu , even it didn't work
3.After so many tries , to my luck , i unrooted my phone with supersu (i don't know how or why )
4.I tried to root it again , but never worked (i tried almost every option available in google).
5.Now as it wont root, i tried to use it as i used to use when i didn't know how to root. But when i installed SDmaid, it says " busybox error "
6.Then i knew there was something wrong with my phone .I googled and tried every method but none of them worked (this is my one last try ). I somehow used my phone till now. But day by day my phone is being worse .
(a)wifi connects to only some networks ,fortunately my home wifi is in whitelist (but when i go to guests house ,its like a virus to me
(b)i cant connect to vpn by any means
(c)the file manager wont copy ,paste , or delete files but fortunately third party apps work for this issue
(d)notification center force closes ,and i have to restart my phone
i hope someone has a way to fix my phone

Hi and thank you for using XDA Assist
My guess is that you completely messed up your device..
But my guess is that you absolutely need to flash back your stock ROM so i came up with this.
For futher questions head over here > Android Q&A, Help & Troubleshooting.
Good luck!

[Resolved] [Solved][Q] Play Store not working after root

Okay, I just Rooted my Xperia Mini Pro (SK17i) successfully (No custom ROM or kernal) so, the first thing i decided to do as being a successful rooter was get Titanium backup through the Play store.
As i connected my WIfi and opened Play Store, it just says "No Connection" Retry.
I have No idea whether rooting had ruined it or what so i decided to head over to the facebook app to see it says "Can't Find Secure Connection"
I have another Android phone whihc is working over the same Wifi Router perfectly fine, I dont know if rooting has ruined my Wifi reciever or something but i need Help Quick
Thanks

ROM toolbox pro crashes as soon As I launch the app

Hey guys, I am new to this forum. I have a problem. I am using Micromax Canvas 4. At first(at the time I bought the phone), ROM toolbox pro worked fine but after reinstalling it few months later, it crashed as soon as I clicked on it. Thought it must be the problem with my System. I didnt pay much attention to it. Now I have installed Xperia C custom ROM on it and it still wont start. After I launch the program, it will say -" Unfortunately, ROM toolbox pro has cstopped working" and as soon as it shows the crash message; it will prompt me for super user permission but even after allowing it superuser permission, it will crash finally. Whats the matter? Could you possibly help me oit guys?

Google Play Store error -505? Help Needed

First off I'm going to start off with sorry if I have the wrong section to be making this thread.
I rooted my galaxy s7 g930v and everything works fine, I used trickster mod & l - speed to fix the whole lag and battery issues so there's no problem there
I downloaded the main root apps I use (Root Browser; Game Guardian; Lucky Patcher; Flashfire; Terminal Emulator; & a few more speed tweak apps)
After a few hours of having root I have had no problems with the phone, It ran smoothly and didn't show anything wrong. When I went back to the google play store later on yesterday I would go to install my basic everyday apps like Facebook & Kik stuff like that. But, when I downloaded them and it was showing the Installing... process It popped up a message and showed "App Could No Install" error code -505? (This error also occurs while I'm attempting to install a apk I had got off other sites other than google play store). I checked the troubleshoot guide they provided, but it was the same stuff they always provide, "Make sure you have sufficient storage" or "Clear data & cache and restart device". None of those had worked :/
I went ahead and factory data reset my phone and cleared dalvik cache and cache and it had fixed it for a little while, then it started again. I am thinking it may be something with lucky patcher possibly & I would want to test that theory. but I am afraid that if I uninstall lucky patcher & it wasn't the problem all along, well I won't be able to reinstall it until I would be able to find a solution.
I hope there is a fix to this, or someone could help me figure this out
Thanks in advance - iiXAtomXii

You will not find any help here. Lucky patcher is a banned and hated app. Many apps are causing issues if it is detected. Things like causing the device to bootloop or uninstalling itself.
My advise would be to stop using lucky patcher. That or find another site.

need help : malware in system

hi everyone !

ist there is a way beside flashing to fix this ?
also my phone is lolipop 5.1 and unroot
Rootkit on an android? Now that's rare. If you tried every conventional method, I doubt anything is going to work. You can try disconnecting from the internet, check your running processes and services, kill them if found, scan with Malwarebytes and attempt to locate problematic files manually using explorer. There have to be some specific apps that are being installed, can you name them?
And full factory reset did not help you?

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

Android system Webview installed but not used by apps

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.
Asking people blowed over 'to buy a new phone'
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)
