Tomas Kopsa deacon at volny.czThe simple answer is: reconnect battery in the phone and try again. When I have experienced this process status, the phone was stucked and it was not possible to load even original firmware. According actual list's discussion, this is probably a timing problem and it is necessary to reset phone's RAM by reconnecting battery. Due to the buffer size, I guess you have cable with FTDI chip (check with lsusb), so you should probably use '-m c123' flag (without xor). - Tomas > ~/src/osmocom-bb/src/host/osmocon$ ./osmocon -p /dev/ttyUSB0 -m c123 > ../../target/firmware/board/compal_e88/layer1.compalram.bin > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 2f / > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 1b . > got 2 bytes from modem, data looks like: f6 02 .. > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 41 A > got 1 bytes from modem, data looks like: 01 . > got 1 bytes from modem, data looks like: 40 @ > Received PROMPT1 from phone, responding with CMD > read_file(../../target/firmware/board/compal_e88/layer1.compalram.bin): > file_size=50932, hdr_len=4, dnload_len=50939 > got 1 bytes from modem, data looks like: 1b . > got 1 bytes from modem, data looks like: f6 . > got 1 bytes from modem, data looks like: 02 . > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 41 A > got 1 bytes from modem, data looks like: 02 . > got 1 bytes from modem, data looks like: 43 C > Received PROMPT2 from phone, starting download > handle_write(): 4096 bytes (4096/50939) > handle_write(): 4096 bytes (8192/50939) > handle_write(): 4096 bytes (12288/50939) > handle_write(): 4096 bytes (16384/50939) > handle_write(): 4096 bytes (20480/50939) > handle_write(): 4096 bytes (24576/50939) > handle_write(): 4096 bytes (28672/50939) > handle_write(): 4096 bytes (32768/50939) > handle_write(): 4096 bytes (36864/50939) > handle_write(): 4096 bytes (40960/50939) > handle_write(): 4096 bytes (45056/50939) > handle_write(): 4096 bytes (49152/50939) > handle_write(): 1787 bytes (50939/50939) > handle_write(): finished > > > It stopped here for very long time, I have tried with XOR and without XOR > for many times!
