Recover WP76XX from bad flash

Hi all,

I was flashing a WP76XX module with some custom SPK while I was doing some testing on firmware signing and such. After one of the flashes, the device started to behave in a weird way and does not boot into the OS.

We tried flashing it again with multiple different SPK (and known good ones) and the swiflash does not ever finish (download stage). During this, we also have an FTDI cable attached to the module and we can see the logs via minicom. Didn’t see nothing relevant, but we can post the logs here if needed.

We also tried the ftd2 tool in windows as well but also did not work.

With a device in this state, how can we recover it?

Thanks in advance

have you tried to change the boot pin TP1 status so that module is kicked to download mode?
