iPad Mini 2 issue

[miticollo]

I tried to send iBEC to my iPad Mini 2. But at first attempt irecovery failed

% irecovery -v -f sshramdisk/iBEC.img4  
Attempting to connect... 
opening device 05ac:1227 @ 0x14200000...

At second attempt it failed with progress bar

% irecovery -v -f sshramdisk/iBEC.img4

I compiled tool on my macOS 12.6 without problems. I successfully sent iBSS but no iBEC. I have no problems with my iPhone X.

Can you check if it works when you change this line: https://github.com/libimobiledevice/libirecovery/blob/master/src/libirecovery.c#L2719 from

	int packet_size = recovery_mode ? 0x8000 : 0x800;

to

	int packet_size = recovery_mode ? 0x2000 : 0x800;

?

Oh hmm just saw it fails in DFU mode already, so this won't help... But wouldn't the device reconnect in recovery mode (05ac:1281) after it accepted the iBSS? I don't remember exactly tbh... In any case it would disconnect from USB and reconnect. Does that happen?

Thank u for the answer. I tried to edit source but nothing has changed. I noticed that after send iBSS on my iPad Pro backlight is present but if I use iPad Mini 2 not. irecovery doesn't disconnect and reconnect iDevices. Anyway with iPad Mini 2 I tried to disconnect and reconnect manually before to load iBEC unsuccessfully.

It's not irecovery that does the reconnect. The devices do it on their own. If it doesn't happen then the iBEC image is not accepted by the device.
