Hello all,
I have few old android phones which I would like to transform to something useful. I have a side project where I can use an old phone to register user action on the "field". I need a simplest android version which can run my application (5-8 buttons with actions) and nothing else. My application need to be automatically started after reboot/turn on and user can't have access to anything else. I don't need phone, I just need WiFi and NFC (phones have NFC). And maybe Bluetooth.
So, I need to build that ROM and upload to my phone(s).
Any ideas, suggestions, experiences would be appreciated.
Thank You all in advance.
Best regards
Alex

Hi there, I'm contacting you to see if you can help me. I've got a S21 Ultra and I'd like to know if it's possible to find a way to get unlimited storage with Google Photos? I checked a bit and saw ways with rooting the device through Magisk or without rooting through VMOS. I'd like to know if someone here ever tried one of these solutions and if the person is happy with the result. Thx in advance for your help.

Hello,
well, I was a silent reader all the time, but I need to confess, I need your help.
I have the smartphone mentioned above quite a bit old.
Is there any chance to get a current version of android on it? maybe a mod, maybe stock, eg.
Thanks in advance

Hi all, I apologize in advance if this question is not in the right section.
I wanted to get some advice about phone hacking protection, I have Android. I am especially worried about hacking accounts in social networks, which I access from my phone. Can you please tell me if you use additional apps? Or is it not necessary, what do you think?

I am not aware of any app, only read about MVT Mobile Verification Toolkit
Hi! I'm sorry that I have to post this, and this is an incredibly stupid problem. But I disabled OEM Unlock on a rooted device with a custom bootloader...
So I was trying to see if all the developer settings were right and I just made quite the oopsie. I don't know how to fix this. I've got a Samsung SM-T580 that I rooted a couple of years ago and it's still rocking Android 8.1.
How do I fix this? How do I enable OEM Unlock? I'm perfectly fine with formatting the device and losing data, because there's not much to lose. I was planning on trying to get Android 10 on my tablet anyways because the WIFI keeps randomly disconnecting. (Android 8.1 bug)
Thanks in advance!
PS: The bold text acts as a summary.
Edit: FIX:
To fix this issue you just need to download the firmware for your device and your region.
Then you just need to download Odin and unpack both the Odin and firmware .zip files.
Watch this video it really helps:
Do Not use the firmware download link provided in the video, because that site is just a waste of time!
Use this site for firmware download: https://sfirmware.com/
Hope this helps anyone!

Good day, and thanks for the response! I'm really new here, I just made an account here just for this problem lol.
Hello,
I recently tried to find a workaround for installing an Android 13 GSI for my Nokia T20 tablet (TA-1392). It unfortunately backfired and now I don't know how to install the new GSI for my tablet without an unlocked bootloader. If possible, how can I unlock the bootloader? If not, is there a workaround?
This is an absolute emergency because I do not know if I bricked my tablet by trying to install a new GSI.

Thank you for the heads up, I'm sorry that I'm unable to properly navigate your site in order to post in the correct places. It's been dizzyingly confusing. No offense intended.

I certainly believe you. A forum with 11+ million members, 3.5+ million threads incorporating 75+ million posts in ??? (I've never tried to count them) fora is certainly not easy to organise to everybody's satisfaction. For this reason, some staff guidances and announcements are stuck at the top of every forum that might be helpful - if read!

To whom this may concern,
As of today, 5/14/2023, I have updated the title of the thread to try to get better insight on my problem.
This is no longer an emergency.
As for today, I have discovered that my tablet was hard-bricked when I clean-erased it back in April 2023. However, with some deeper research, I found that it is recoverable. In terms of how, since the tablet tends to, when turned on, intermittently get detected by my Windows 11 desktop as 2 different identities, I need to somehow install/flash something onto the tablet within that split-second of identification to keep it from turning off while flashing the GSI. OR: have a tool that is not the HMD DeviceKit, as I cannot get permission for my Microsoft account to access such an app. I have no fastboot or recovery mode, as that was erased when the tablet was bricked.
NOTE: The GSI that I have installed is a stable version of Android 13. It has not yet been flashed onto the tablet as of the time this post was published.
Hello Again,
I have done more research and found out that I need to put my tablet into EDL Mode. In terms of how to do so, I do not yet know. In this later research that I made over the past 24 hours, a hint points me to the internal pinout of my tablet. Can someone help me identify the pins that I need to short out to enter EDL mode if possible? Or, if this hint is not true for this device (Nokia TA-1392), can someone point out how else to enter EDL mode on my tablet? Please note that the info about the GSI that I posted yesterday is still valid.
