Factory reset of wp76XX

Could you please assist me how to do a factory reset of wp76xx series. Currently, I had an application which I am not able to uninstall, I already deleted the install folder and all the related files. The corrupted application also blocks other application to install or uninstall.

Hi sowvikroy,

Please try swiflash tool “-r” option, please refer to below for more info:

Thx

Is there any other process to restore the device from Developer Studio or Windows machine?

Hi @sowvikroy

From Developer Studio, in the recovery wizard (from the Device menu), you get the Erase user partition option which is exactly the same operation that swiflash -r

Getting this replay!
Option not supported for selected module (“WP76XX”)

Hi @sowvikroy

What WP76 SDK version did you install in your DS?
This behavior looks like a legacy one and shouldn’t occur on recent SDKs.

SDK details of DS

Well, good catch, there is indeed a problem on Windows.

As a workaround, you can:

  • go to this folder on your system: C:\Legato\Packages\legato.recovery.2.1.0.1702_3.win32-201803051239\resources\reset\WP76XX (may be different if you didn’t installed in C:\Legato
  • rename the wipe_mntflash_wp76xx.cwe file you find here to reset.cwe

Then the reset option should work as expected.
