Thanks for repply

After a bad flash, this methode doesn't work (I think u-boot.bin is corrupted)
The sdcard is scan but installation don't start
So we need u-boot.bin, android_boottext, ...

The model exact is Jay-Tech PI799 (same Kliver PI799)

Edit: I find another clone (Smart Touch X210 & Overmax OV-TB-02) maybe they are the solution for us.
