Xiaomi Yi 25L update problem

[nickxab]

Hello all.
I have a Xiaomi Yi 25L model and i downgraded it to 1.2.13. now it appears as 22L,23L on the official xiaomi app.
I downloaded the the 1.5.6 FW to install manually but the installation doesn't start. Also i tried to upgrade it using the app to 1.5.12 but it stuck...
Any way to return it in 25L model ? any elf ?
Thanks in advance !

Do you mean the official Yi firmware site where you select the fw number ,enter your 25L, and press download?
My Z231 cam seems not to like downgrading firmwares to 1.5.6 from 1.5.12 to use autoexec.ash hacks like Yimax, it goes into a circular beep...beep,beep, and I have to revert back to 1.5.12 for norml operation!
