Phone Locked - Samsung Galaxy A70 Questions & Answers

Hello everyone,
I have a Galaxy A70 on latest May 2021 One UI 3.1 update, phone was working fine till this morning, when I tried to manually update some system apps.
I downloaded Device Services latest release from apkmirror, once I installed it, the device showed a "Phone Locked" screen, with IMEI on the next line, followed by:
"This phone can't be used without authorisation"
WiFi was connected for a few hours, I can receive phone calls, even Whatsapp calls, Google Assistant & Bixby are working fine, everything is cool except the fact that I can't bypass this lock screen.
I can use ADB, my bootloader is still locked, my phone has never been modified. I don't want to lose internal data by doing a factory reset.
Any help would be marvelous. Thanks.

[Q] Google Wallet on CDMA GN No Longer Working After Wipe

If anyone is able to help me, I would greatly appreciate it.
I installed Google Wallet (via this APK) when I first got my Verizon LTE GN a few weeks back. I've since used the app daily and it has worked perfectly, up until this evening.
Today, for the first time ever, I decided to unlock my bootloader in order to root my device--all of which went smoothly. I then re-downloaded the above GW APK (since unlocking wiped my device) but now when I launch the application, the screen stays at "Initializing your device - This may take a few minutes depending on your network connection." The application doesn't freeze (the circle continues to spin), but after 30 minutes of waiting, still, nothing has happened. I've tried reinstalling the APK but that does nothing. I have 4G connectivity and have tried over WiFi also.
I am running stock recovery, stock ROM, stock everything on 4.0.2. All I did was unlock the bootloader & root the device. I've done quite a bit of searching but have been unable to find a solution. Does anyone know what may be causing the issue or what I could do to fix it? I really enjoy using the application
I'm having a pretty similar problem.
CDMA Galaxy Nexus.
When I first got the phone, I downloaded the Google Wallet apk and it worked fine. Used it a few times out in the real world.
Today, used the wug unlock/root method, and installed a custom rom.
Though the rom feature log said it contained Google Wallet, it did not.
I redownloaded the original APK that I had used and it installed, but now I get this "Unfortunately wallet has stopped" message every time.
In fact, it comes up on the screen at random intrevals.
Not sure if there's anything I can do.
Do you guys have NFC enabled from the settings menu?
Also, did you try disabling and re-enabling NFC? It's different hardware, but after flashing one ROM I had to disable/re-enable GPS before it would work... worth a shot.

android pay not working after flashing stock

So I tried doing the systemless root thing. I tried confirming that android pay would still work by removing my cards then attempting to re-add them and it failed. I tried undoing what I did by flashing stock recovery, boot, and system. Still a no-go. I tried running the flash-all.bat (i removed the "-w" so I would keep my data). Still can't add a card.
I resorted to running the flash-all.bat, build MDB08M, to be 100% stock. I STILL CANNOT add a card. The message has been the same every single time "Android Pay cannot be used - Google is unable to verify that your device or the software running on it is Android compatible"
Am I missing something? I don't understand how a 100% stock flash is not able to work.
If it makes you feel any better I've been running 100% stock since day 1 and tried using Android Pay for the first time today. Failed same as yours saying device or software couldn't be verified. I had originally set it up using my card that was already set up on my Google account. When this card didn't work I removed it and tried adding the card again manually. Couldn't even add a card. Tried rebooting several times and disabled developer options. Still not working.
I can select a card already on my google account, accept the terms, then the message pops up. Happens with two different cards associated with my account.
I'm fully stock, but unlocked bootloader.
Android pay used to work as recently as 4 days ago, but failed today with the error unable to verify.
Not willing to relock bootloader. Was there an update of Google play services that changed the way they check for modifications to include bootloader unlock?
I went back to complete stock relocked bootloader and Android paid don't work for me because chase bank stopped supporting Android pay so I went back to custom ROM
Just to note my bootloader is unlocked, otherwise I am 100% stock.
I manually tried updating Google play services to the latest version, but Android Pay gave me the same message but at a different point in the process - right after I clicked "Add a credit or debit card." I wasn't even able to see cards already associated with my account like before. I ended up uninstalling the update because it seemed to make things worse.
I just tried this app and it says I'm failing the SafetyNet check:
https://play.google.com/store/apps/details?id=com.scottyab.safetynet.sample
Same here. Completely stock 5x with nova. Had added a card, but wasn't working so I deleted it to try to re-add. No luck... Pretty annoying actually. I don't use it that often, but there have been several occasions I forgot my wallet going to the grocery store and paid with android pay cause it's all I had. Hope it gets fixed soon.
Looks like it is working all of a sudden. I was trying the safetynet checking app a few times a day... just tried now and it finally passed. Gave android pay a whirl and both cards were able to be added without issue. So apparently something happened on Google's end. Google play services is the same version now as it was when android pay failed to work.
I was failing the safetynet API yesterday. I still am.
I was also unable to pay with anything yesterday, but today I was able to add a card. Presumably it's partially fixed.
I went completely stock with relocked bootloader and STILL failed the test.
If it's working again, it's probably something wrong on Google's part. I'll try adding a card with systemless root
Ugh, what a headache, I ended up deleting everything for no reason.
Anyone else find it to be working now? I ran the safety net check last night and it passed. Tried adding my card and this time it worked. Big G must have fixed something on their end.

Marshmellow 6.0.1 Unable to communicate with Google servers

Hi,
I'm fairly new to the Android rooting community, that said I have been jailbroken on iOS since the days of 1.1.2 and have rooting experience with KitKat. I have a Nexus 5X and after rooting, the phone worked fine. I installed TWRP 3.0.2 and Xposed framework, but for some reason I was unable to get Xposed to work. After a week of no issues with the phone, the Play Store stopped working, and Hangouts failed to send messages. I could send SMS via Messenger app and would receive the replies in Hangouts. I did a factory reset, and now I am unable to do anything. I cannot login to my google account, use the play store. Whenever I do anything I get a message that says:
Couldn't sign in
There was a problem communicating with the google servers.
Try again later.
I've searched the web and the forums for issues like this and can't find anything. I would really appreciate the help. It may be a simple mistake that I made as I am not fully aware of how the Android filesystem works.
Also when I check for updates, it stays that the last time it checked was: 12/31/1969. My clock is set correctly and I am connected to Wifi.
Wow!!! What ROM and gapps are you running?
I haven't seen this since my LG G2 a couple years ago. Hop in date and time in your settings and turn off automatic date and time and manually add it... Unless you're saying its right there.
I would try going to TWRP and wiping.
Wipe/advanced and then check every box except for internal storage. Then hit home and go back to install, choose ROM then gapps then vendor.
Xposed has to be installed as a zip from recovery before you can install/use the apk (in 6.0.1 anyway-use arm64).

What happens if you try on mobile data?

Unfortunately I can't use data either since I am unable to activate my project Fi service (since I am not able to make any data connection).
I've resolved this by wiping and installing PureNexus. No idea what was going on with the factory ROM though.

Any chance you changed your Google account password around the time you reset the phone? I think there is some lockout mechanism if they detect password change then factory reset. I believe it is something like 72hour hold.

WIFI - Begging for help!

Hello. Im here after wasting above month on official MIUI and Google forums. Xiaomi never answered, and Google is telling me "this is not proper thread" everywhere, and it looks like they have no support for my phone.
So problem is, after upgrading to Android Pie, my wifi stopped working for Youtube, Gmail and System Updates. Those 3 Necessary apps for me need to, MUST work on wi-fi.
What i have done so far:
- Changed router
- Wiped phone (at least 9 times)
- Flashed Official rom from MIUI page..... (few times)
None of them worked plus i got another problem. After flashing Android 8.1 from miui, my sim slots have swapped in system - now sim 1 is sim 2, and sim 2 is sim 1. I knoew it may happen, but even on 8.1 wifi have not fixed itself, so i doubt its something with device, but with some drivers.
I also downloaded ROM from MIUI in Pie version (released week ago or so) and it also not working, same issue. I even had downloaded some update on first pie version. Now its very strange - when i had first Pie (before flashing 8.1) i have downloaded update - to seek for updates i need to use mobile data - thanks for my location only 2G is working, so its slow as hell, when update was found - i downloaded it with wi-fi.
With Youtube its also strange - i can make it working by turning ON wi-fi, launching app, turning wi-fi OFF, and ON and voila. Sometimes it works. I started also using "Secure VPN" app to make Youtube loading - it works, but not in way i wanted to - i need YT working for chromecast - with VPN i cannot connect to chromecast.
Finally Gmail - it sometimes - very rare working on wi-fi, but very soon after i think it fixed itself it again stop to working.
For flashing i tried used mi flash tool, and script commands included in image folder
You can probably try that : https://forum.xda-developers.com/showpost.php?p=78496783&postcount=40
Edit : this kind of stuff is a bit sensitive, keep in mind you can brick your phone, I don't know if it works I haven't tried myself, this is just a suggestion that looks similar to your problem (Sim swap, and it makes sense to me that the modem.img is also managing the wifi board (but really not sure about that).
BTW, I would do that with the Oreo ROM since I think the message is about Oreo. Then you can upgrade to pie again and see if you still have problems.
In my case, enforcing ipv4 in the router / access point settings has repaired WiFi.
I had issue with twitter, twitch, sometimes YouTube. I Could not access some websites.
I have no ipv6, i have tested this on 2 routers, now i'm checking 9.6.4.0 rom as i heard it have proper modem.img.
#kidoucorp - i'll try this also. I have tried updating to pie 3 times - i havent writed about this
So currently i'm out of options. Tried solution from your link, but it doesnt work
Wifi have worked like a charm after flashing 9.6.4.0 but my sim card wasnt working, system was saying its sim 2, so i wiped it for sure, now wifi is not working again, even after second flash with solution from the link. I wasnt able to login into google accounts, so i tried these steps from google help :
"

Still problem persist,
Try after few hours.

And now i have signed into google, but google play store is plain white page. It wont download any updates as wifi is not working, and on LTE/3G/2G i cannot seek for any updates (default play store setting to download only on wifi). Android one is trap, never gonna buy device with this. Looks like i'm gonna try to sell this phone, but i dont know whos gonna buy it.
Any more ideas?
So i make it workable, but i cant login into damm google serwers. I hate everything that startd with G and have 2 oo inside.
What i have done :
- Downloaded 9.6.4.0 Fastbot image from here : https://forum.xda-developers.com/mi-a2-lite/how-to/ota-v9-6-4-0-odlmiff-t3823913
- unlocked bootloader again
- Flashed image without any changes via miflash
- On first config i choosed to not connect with mobile data or wifi, just skipped it.
- I configured phone once i saw desktop;
- turned off localisation, BT, switched to 2G, configured APN's,
- Configured gBoard, disabled Find my device, disabled FMD from administrators of device, disabled smartlock, and configured google settings so it cannot collect so much my data
- configured sounds, AND WIFI.
- Once i had wifi connected i went straight into SYSTEM UPDATES.
- I saw IT IS DOWNLOADING UPDATE FROM NOVEMBER without any notification. Pissed off about it, i went to developer settings and turned off auto updates.
- Went back to System updates and it was freezed on searching bar and nothing more, so i enabled autoupdates back, i get error it could not update, and in second try it updated.
- YT is working but i cant sign in to google serwers, "try again later".
So now i think i get what is hapening here. Android Pie, Google new owner, everyone have problems "with wifi" - that all BS.
Nobody have problems with Wi-Fi - wi fi is working well, in chrome, or any web browser its working, so DEVICES ARE FINE. Its Google serwers, google apps (using THEIR SERWERS) not working. So i guess new owner have no control ower everything and serwers have half of its speed, so lot of users sometimes have working gapps, sometimes not. If it could be only apps i at least could login into damm google account. What is not fitting into my idea is why PC versions are working OK - mobile devices are using different serwers?
PS : If anyone have Pie and having issues with wifi - try to logut from google account. All should start to works.
PS 2 : i logged into google store via secure VPN - again wifi is not working without VPN.
Phone is useless. LTE and 3G are working 1/5 its speed, its better to use 2G, Wi-Fi is not working on Google Apps. System updates are not working (infinite searching). Only thing that works are browser, messenger, SMS, calls, Deezer.
I dont get how people can not have this issue at all, what its dependent? I tried creating new google account - phone will not login into it. "Problems connecting to google serwers, try again later". Its most sh***y ROM ever created. Never had so much troubles on any custom rom on any phone. Thank you Google, f u G.

Have you tried Settings - System - Reset Options, then reset the WiFi from there?

Did you update the apps not working to the newest version? Otherwise if you have an unlocked bootloader (which i guess if u used the fastboot flash scripts) you could try to flash opengapps with twrp. Or you could get a logcat on a fresh installation and see if there is really everything ok with the rom.
have you tried joneplustool, you need root, but i did was toggle wifi bonding and my wifi started working fine, only had to do it once, but i suggest to flash magisk and use qualcom wifi bonding module.

All apps are updated, Google Plays Store is normally working, device is certified and udpates are normally working (for apps). Only problem was loggin into google account but after 7th or 8th try it worked. I dont have custom TWRP and have locked bootloader (scripts are doing it manually after finishing the flash). I dont try with TWRP and custom ROM's as i'm not familiar with it on this device (I have installed multiple mods - roms, recovery's. modems, etc on Redmi Note 4, but it was much easier). I'm also not familiar with logcat and its script language.

Well, at my work WIFI is working fine (for while), i have straight connection in work. In home, "friend" is sending me a signal (but its very hard to ask him for help) and i'm receiving it via wi-fi in my home. What he told me, i dont have ipv6 (he's not also). I tried 2 routers in my home - 5Ghz and 2.4Ghz - both same issue. In work i have 5Ghz, but 5 is not fitting to my home - i got low signal in the bottom of the house while router is on upper floor, lot of metal tubing, etc. its old building style home and it have some cons and props.
Well, friend have changed something about DNS, system updater, youtube started working, he said there was some problems with 8.8.8.8 on my phone. after 15 minutes system updater again searching for updates infinite time, in 2G it works flash fast. Youtube still works, but who know how long... Any ideas?
BTW xda page also wont load on wifi....

Question Update to Android 12 fails at 25% each time

I have an unlocked Fold 3, purchased directly from Samsung. When I try to do the OTA update to Android 12, after the reboot into the updater (the robot screen), it fails every time at 25% and then reboots back into 11. I have verified Google play services are up to dare.
Anyone have an idea other than doing a factory reset and then trying?

Are you taking an OTA update that was pushed to your phone? Or are you trying to manually update it?
If it's the OTA, use Odin to do a fresh install. You will likely end up losing stuff but that makes it a clean install. Backup everything, screen shots for things you can't just backup, and you should be back in the saddle.
There's not much else you can do via OTA. Even Sammy will suggest a reset, but they aren't much help anyway.
Try using Samsung smart switch through a pc. Connect your phone to pc and there you can select update and it shall update your phone. Hopefully this will pass without issue.
