Android - 5.1.1

Well it just needed an active wifi connection to use the net for updates and previous google account. If you forgot your account use an OTG device with a usb, this will automatically open your browser and you can reset it. Check this video.

"Unlock gone"

Hi guys
Have any of you suffered from this?
I got my TMO S6 edge unlocked bought it from a 3rd party about 2 years ago, been working with different companies here in Mexico without any problems, never had any problems with not accepting different cards.
Last night, phone still Ok, but on this morning i wake up and phone has shut-off, and after power on it, now it not longer unlocked, its not accepting any of my sim card from different companies across Mexico, it says "Network locked SIM card inserted"
And getting this screen everytime i reboot

I try with device unlock and it fails with this
I dont have any TMO card
I checked my IMEI on TMO database, it shows status OK
checked also on Mexican organism for it, and it also shows status OK
So i came to think, something like "unlock is gone"
Has any of you have come across something like this?
Really need to be able to recover my phone line x.x
Thanks a lot in advance for your replies

Save me from android 9!
so i've been using a S10+ that i got from a seller on amazon that said it was an unlocked At&T display model and i got it working on metro over a year ago and been working great since. Problem being i've never been able to get OTA updates and i really want to get to android 10. Now when i connect the phone to Smart Switch on windows i get -
" you device software is up to date (SD3 ATT)"
and then above its on android 9 version 9.0.0...
Model for the phone is a SM-G975U
I havent used Odin in almost a decade it feels like (Galaxy S3 custom Rom) and i'd like anyone to point me to the proper method and possibly a source of where i need to get the proper install files for android 10 for Metro PCS. Can't find much if anything anywhere besides XDA forums being of any help.
any guide or tutorial and links for what i need to do would be a life savers please thank you in advance will be checking on this thread daily
Check Samfirm.com I think it is and this thread out:
https://forum.xda-developers.com/s10-plus/how-to/g975u-g975u1-firmware-links-t3905897
You will need the patched version of Odin to flash any firmware too.

OTA 14.0.19 No SIM or mobile network after reboot

HD1905, OOS 10.0.13.HD65AA, no weird Magisk modules installed
On 10/20 Oxygen Updater notified me of OTA update 14.0.19. I followed all of the usual steps and updated without issue.
On 10/22 I rebooted for the first time since the update. After the reboot my phone could not see any information about the SIMs or the IMEI (see screenshots) and any attempt to dial returned an error that call management kept stopping.
The update was still in storage so I forced a redo. Everything worked fine after the final update reboot.
Restarted my phone and, again, SIM not seen and no mobile network info.
Lather, rinse, repeat several times over the next few days.
Mobile network, phone number, all SIM related functions work fine after the update until the next reboot. After that the OS doesn't see anything SIM or mobile network related until the next forced redo of the update.

I think you need to be on Magisk 21, not 20.4.
Install the beta over the stable version?

MRX-AL09 Can't update to HarmonyOS 2.0

I have 11.0.0.227(C432E3R1P6) version on my Matepad Pro 10.8. I switched region to China in device settings, in My Huawei app and in App Gallery. Updater didn't find any update. I've even done factory reset and it didn't help.
Maybe there is an option to manually download and install HarmonyOS?
Same problem here, been looking for a few days on if it is possible to update to harmnoyos or not. Starting to point towards no.
Guys @mimss , I don't know how long this solution will last. Today I wanted to test an app which enables to use the tablet as a monitor or drawing pad. When I connected to my tablet to windows PC(with included USB cable) the HiSuite opened and required me to update it. I updated it to 11.0.0.650_OVE. After connecting the Hisuite with the tablet, I clicked on update, It showed me a new available update HarmonyOS2, so I hit download. now it is downloading and installing (Not done yet). A week ago I changed the My Huawei region to Vietnam also the App Gallery. so you should do it to. I also have the MRX-AL09.
