In my case, all the software that I found with 10.1 gave me an error when decompressing, I downloaded from various websites
So I decided to try 10.0 and it was a success

1) Load FastBoot via Test Point
2) Get device info
3) Make the 3 different backup copies
4) Read firmware (optional for security)
5) Write firmware YAL-L61 10.0.0.197(C432E3R1P2 (all 6 files)
6) Restart the cell phone with = Software testpoint On.../Off (because when the flashing finishes it stays in fastboot mode)
7) Enjoy the cell phone
