No Root SSH ACCESS on WP7702 FX30

Hi @jyijyi ,

My two modules are now unlocked to access SSH !!! thanks to Sierra FAE “Chau” and you @jyijyi .
He gave me instructions so as to unlock with a key and After performing these steps, the SSH authentication credentials, data, and applications in the FX30 device are removed.

root@user:/home/user# adb shell
/ # flash_eraseall /dev/mtd16
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it
Erasing 134144 Kibyte @ 0 -- 0 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 0 (mtd16)

/ # reboot

Thank you for your first help
