[E 2015 Q&A, Help & Troubleshooting] chris1892006:
Your device does not qualify for bootloader unlocking.

I get that on the official Motorola Unlock site for my AT&T XT1527 Surnia.

Any advice?

Also I cannot get RSD Lite to work either, no detection on a Win11 Ryzen system with only 3.0 ports on my ITX X570 i Gaming motherboard from ASUS.

Thanks

I tried the flashfile.bat script that fastboot flashes the stock 6.0 firmware and it gave a lot of errors and wiped the os and rebooted to 5.1 again.

So at the bare minimum i want 6.0 but don't know how without a USB 2.0 hub or some such.

I tried these roms stock firmware, they fail preflash validation failure.
