Hi folks,

unfortunately I somehow bricked my ZTE Open. I flashed cwm (worked fine) but after flashing both system AND userdata via flash_image, the phone won't boot and what is much worse it won't boot into cwm anymore as it hangs there with just showing the logo and the cwm version. The menus are missing, it does not react buttons and does not show up in adb. FTM mode is also non-functional, holding volup gets you also into broken recovery.

For earlier ZTE devices like the ZTE Blade it seems to be possible to low level flash them in diagnostics mode. Diagnostics mode is working fine on the ZTE Open (it shows up with the diagnostics port on USB. Luckily I also have all the 20 partitions backed up, but I don't know how to flash them in this diagnostics mode. I tried putting the files into the root of the SD card and including sha1/256/512 plus md5sum files, but it was not impressed by that. Not sure if this only works in FTM mode, though.

Any help would be highly appreciated! I highly assume that the procedure is the same as for the ZTE Blade.

This may help. http://pof.eslack.org/2013/07/05/zte...t-impressions/

At least there is more going on for Firefox Open over there.

Thanks but as you might have noticed I posted several comments there already, but I thought XDA would be the right place for unbricking devices.

Thanks for your time to help, but this does not work for me. I get an error, when I press flash button (printscreen under attachments).

I've tried to probe the pins with the multi-meter and found GND and V+ (picture under attachment)

Now it would be nice to have something like this -> http://www.grandideastudio.com/portfolio/jtagulator/

Thank you for the link. But what tool is supposed to be used to flash the files? And is there a way I can use my backup as well? In this case: how can I transform it to TPT files?
