Could you help me to find what can I do to manage my device correctly with edl tool?
Well, it read the first sector ok and acked. Then it "Timed out". Was that on read or write or what? Who knows.

It was read. For unknown reason it expects more data from the device when device already sent all GPT data
I patched quickly the cmd_read_buffer function in firehouse.py and now it reads GPT and data if I use --memory=UFS argument:

I believe it can break compatibility, but at least it fixed issue for my device, so the issue is on the edl script side. Let me know if I can help with more info
For some reason it missed the ACK and kept on looking for it. Was this on Linux or Windows with WinUsb or the Com port driver?
