Script to copy files to phone

[langbeck]

With this script we can push files to phone using several EXEC blocks (with optimal payload size) to transfer a file to phone.

Just one more thing. I have a D805 and I need to adjust EP_IN and EP_OUT to 0x83 and 2, respectively.

Please use print(...) for Python 3 compatibility

Hi Dorian, thank you for your interest and PR! I have added some inline comments.

About the endpoint numbers, can you post a subset of the lsudb -v output for your device? See 2d79e15 for what I am interested at

Also an additional tip for those who need something with low overhead: you can actually rename /dev/block/mmcblk0 and make a symlink or something. Then OPENing it for writing will allow you to use WRTE commands to transfer a whole file. Alternatively, write to an unused partition and use something like dd if=/dev/block/mmcblk0pX bs=$size count=1 of=/path/to/output/file

[langbeck]

I actualy thought in replace /dev/block/mmcblk0 by a link but I not tried to implement. I'll sent and lsusb subset for D805 when I get home. I also tried in my D855 and I think that I have to adjust the endpoints too (I don't remember well). I'll check that and sent these informations in the next patch.

[Lekensteyn]

I would not recommend renaming the mmcblk0 device unless the user is absolutely sure what (s)he is doing (and then I would still be careful). The D855 is the European version right? That is the one I have tested this project with.

One more thing. partitions.py --list doesn't work for me. The line 35 uses try to list /dev/block/bootdevice/by-name, but in my devices (D805 and D855) the right path is /dev/block/platform/msm_sdcc.1/by-name.

[Lekensteyn]

About the /dev/block path, my D855 has both, but on newer devices only the bootdevice path is present. I guess that some fallback is needed here.

[langbeck]

Initialy I created a new parser argparse.ArgumentParser(), but soon I realize that the options you offer in ./lglaf.py (such skip hello and COM port) should be present in others binaries. I think extending lglaf.parser is a great way to avoid code duplicatation. What do you think?

[Lekensteyn]

The --skip-hello is normally not needed (it just reduces noise during debugging), --serial on the other hand might be useful at more places but its interpretation is completely up to the program. I would say, for now minor duplication is acceptable.

If some common arguments are needed in the future, then it could be added as needed.

[langbeck]

I can't see the merge button... maybe only you @Lekensteyn can do it.
