Mifi 6620L Unbrick

[brandon63]

Have a nice day


I have a Mifi6620L device and it was interrupted while updating and now my device does not turn on and even the charging screen does not appear. When I connect it to the computer, I understand that it is in EDL mode. I did a lot of research to revive my device and found some information with qtools, but I think partitions.xml and patch.xml files are required to revive the device? I would like to share the data and screenshots I obtained below. I would be very grateful if you could help me get my device working again.

You need firmware to load to it from a working device, also there are 3 different nands that these devices were made with. toshiba, micron and Hynix.
they can be 2k or 4k filesystems if your device is Toshiba nand it must be loaded with firm from another Toshiba nand device, if its Hynix or Micron they are interchangeable. You only need partition.xml if you are going to use a tool like qpst to load it not with qtools.

Is it possible to repair the device by connecting remotely or share the partitions.xml file if you have it? As far as I understand from Qtools, there is Toshiba NAND in the device.

You do not need it for qt, I never made one or got one because I never needed it with the tables below neither should you
if you are using qt
The partitions are as below
