Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
As I have said, TWRP doesn't boot with this A12 rom. Anyway, updating to a major Android release requires a full wipe. What I always do is backing up my apps using Titanium Backup and restoring them later.
After some weeks not using my X Neo I decided to flash the 6GB modded global rom and, since the crDroid GSI seems to be discontinued, I flashed the A12 Pixel Experience +. And it's working like a charm! This little tablet that came with Android 9 and was never updated by Alldocube now is running...
I flashed crdrom-v313-210921-arm64-bvZ.img.xz because the bvZ version is too big for our system partition.
I don't know why but the only version of NikGapps that I've been able to flash is NikGapps-core-arm64-11-20210130-signed.zip. It's not a big deal because after booting the core gapps are...
The setprop command has to be run as root in a terminal. It worked for me.
Don't go back to Android 10, if your headphones don't work using the 3,5 slot buy a usb-c adapter.
I think that to be able to handle external cards Titanium Backup has to use the document provider storage. And it's recommended to disable Play Protect and "Verify apps over USB" .
No, I haven't, I use the tablet most of the time with headphones and I'm getting great audio quality with them, specially now that I'm using a usb-c adapter. Magisk is working on crDRom so I suppose that ViperFX should work.
Yes, once I am in Android 11 I can do a dirty flash between versions. Titanium Backup handles external sdcards and I still use it although it hasn't been updated in a lot of time.
Coming from Android 10 you should do a clean flash. The best way to keep your previous settings is making a backup of all your apps with Titanium Backup and restoring them later, it's safer than restoring a full data partition from TWRP.
I have installed latest crDRom 21.04.28 coming from previous crdDRom version and it's working like a charm.
For the wired headphones issue type the following command as root in a terminal:
setprop persist.sys.overlay.devinputjack true
Although now I'm using my headphones plugged in the USB-C...
