Bricked my Boox Palma (stuck in memory dump mode)

[paviro]

Hi,
I rooted my Palma a while ago and then thought I reflashed the original boot partition. It seems I did not as I could not install the latest 4.0 update and it always failed.

Being a bit naiv I tried reflashing the phones partitions from an extracted payload.bin from the 4.0 release via fastboot but after a reboot I am now stuck memory dump mode.

When trying to write an image via edl I instantly get:

Qualcomm Sahara / Firehose Client V3.62 (c) B.Kerler 2018-2024.

It then goes on dumping all sorts of things. Any tips on how I can recover my Palma and restore a 4.0 firmware to it, right now I can't even get into a boot loader.

Thank you so much for any help,
Paul

It looks like you're in 05c6/900e, much less useful than 05c6/9008.

You can try holding various buttons during reset to see if you can get to recovery or bootloader.
Reset is long (10 seconds+) of the power button.

If not, an EDL cable will get you 9008.
