Factory reset FX30 into a strange state

1

Hi,

I factory reset a FX30 which runs FX30_WP77xx_full_R15.0.4.001. The device goes to a strange state and cannot update firmware afterwards.

Whe the device is logged in, it pops up two warning lines as below,

root@192.168.2.2's password:
touch: /mnt/flash/config/system/etc/noLoginNag: Read-only file system
touch: /mnt/flash/config/system/etc/noLoginNag: Read-only file system

If I update the firmware, I straight away get the error on PC side like below,

$ fwupdate download installers/FX30_WP77xx_full_R15.0.4.001_62a8f41c-telstra-SWI9X06Y_02.36.08.02.cwe

root@192.168.2.2's password: 

cat: write error: Broken pipe

And the log on device side:

Also no luck with swiFlash,

$ swiflash -m "fx30_catm" -r

Any thoughts and suggestions how to bring the FX30 back? I wish I don’t have to open the FX30.

Thanks.

module can enter download mode after typing AT!BOOTHOLD
after that you can download FW by swiflash in linux or fdt tool in windows

Please note that the “-r” option can only be used in old FW of WP77:

Thanks @jyijyi. Followed one of your suggestions in the thread and erase the userapp brings the device back to normal.
