I have the tmobile smn950u snapdragon note 8. 7.7.1 is the android version. i am completely rooted via samfail u3/v3. my bootloader version is FA71_N950SQU3ARA1 my firmware is QU3BRA9. When i install a compatble room into the safestrap environment it doesnt boot the logo to the rom. After i press continue on the safetrap logo it boots up to just a black menu left it sitting down its boots up into the virtual stock recovery. then i hold the 3 key combo to boot back into the regular rom from safestrap. how do i go about using the rom slots properly without the black screen of death ?

Hi, I had a problem when trying to swith from BMM to Safestrap; I lost the recovery and the ROM didn't boot.
I used RSD Lite to flash the original fastboot, and the process was ok, but after installing the ROM stucked in the bootanimation (not the initial boot logo)
So I restarted to stock recovery and made a factory reset. And then it get in a bootloop, only reaching the boot loho (not the bootanimation)
And I'm not really sure if I pressed power + vol- or both vol- and vol+, but the phone rebooted and started to work.
The stock ROM is working, but I have a "safe mode" stick on the botton of the screen, and I don't know if I can root it again or I need to change something before doing that.
Thank you!
Was trying a factory reset with the idea that I'd give my Tab s3 to my wife upon receiving my S4.
The s3 was rooted but had the stock ROM.
I booted into recovery (TWRP) and did a wipe to factory reset. I had used TWRP a lot and didn't take my time. Just as I was moving the slider i read something like "sure you want to do this you have no OS installed." Too late.
Now it is stuck on the splash screen. I can't even turn it off.
Thoughts?
Thanks

You can either flash stock firmware from download mode (vol down+home+power). You can force reboot with this combination even if it's stuck at samsung logo (after screen gets dark, keep pressing them to get to download mode). Then you can flash with Odin a stock samsung firmware.
The other option is to use this rom https://forum.xda-developers.com/galaxy-tab-s3/development/rom-sm-t820-tweaked-t3659433.
Copy it to the microsd, boot to recovery (in this case you have to use the same 3 button combination, but as soon as the screen goes off, you leave the vol down and press vol up along home and power buttons.
That would take you to TWRP and then you could flash that rom.
The first option is the natural one but both should work.
Also, for the second option you need the actual bootloader to match the custom rom.
So if you're in Nougat, flash the Nougat rom. The same for Oreo.
Thanks. Worked perfectly.
I'm having a bit of trouble with this. I've already been through NMaverick's guide, to very limited success. I was able to flash an older version of my firmware with SP Flash Tool, and get TWRP flashed and booted into recovery, disabled encryption, and installed Magisk. My screen is flickering, so I don't want to leave it like this.
Does anyone have any advice on how best to move to the newest firmware without losing TWRP/root?
Just to add: With my most recent firmware available, the screen doesn't flicker, all the stock functionality appears to work fine, but I can't boot into recovery. When I hold down Volume Up, the phone acts like it's stuck in a boot loop. I get a green line across the top of the screen after the boot logo, and then it tries to boot again. Letting go of Volume Up results in a normal boot to the OS.
Hello everyone, where I can find this version for the 3T or if someone has it in Backup, it is very important for me to find it:
CQ3060MF2_AGS32_Armor_3T_20181107_V01
Thank you
I installed stock Android 10 Q (from 9 P) via Odin on my galaxy tab s6 LTE, then i unlocked the bootloader and rooted with magisk (manager 7.5.1, zip 20.4) following the magisk git site installation instructions (which are a bit more complicated than from some third party sites.)
Everything ok, but then when i power off it reboots. It's not in a bootloop: it boots up normally, but if i can't power off then that's not good when I'm not using it. I tried patching again and checked i got the the same md5.
Eventually i found that if i booted to recovery mode and there i choose reboot, it reboots to unrooted, but it does power off.
To get root access again i start with the recovery key combination but let go at the splash screen before it enters stock recovery mode. This means that i have to reboot each time i want to either switch it off or have root (but not both.) It's good enough for now, so I'm posting this in case anything else has the same problem.
Edit: I used Odin to flash back all the stock firmware and I can now get back in the tablet. Any idea what I did wrong with Samsung Multi Disabler?
Was trying to flash my tablet and was mostly done but after trying to flash the Samsung multi-disabler the tablet will no longer boot. The Samsung and Knox logos come up with the Red Text warning about the root but the screen then goes to black and the device reboots. I am able to get in to download mode but I am unable to get into Recovery Mode as the button combo will not work.
1: I unlocked Boot Loader
2: Rooted with Magisk
3: Disabled VBMeta
4: Disabled Android Safeboot
5: Flashed the TWRP for Android 11
Everything booted just fine at this point so I flashed the Samsung Multi Disabler using the "TWRP Manager" from within Android. Now my device is stuck a boot loop and I cant get out.
Any help is appreciated.
