Issues with heimdall with the Android 2.3.6 bootloader on I9100G_CNH_CHN¶
On some laptops or desktops, heimdall works fine, while on some other it doesn't. The issue is that if heimdall doesn't work, your device could be stuck in "pc screen" mode, and you might not be able to recover from it.
On the following laptop it worked fine:
- Thinkpad X200 which has USB2
- Coreboot 4.9 without any nonfree firmware or microcode
- Parabola i686 with linux-x86_64 kernel
On the following desktop heimdall didn't work, which made the device stuck in "pc screen" mode:
- Asus F2A85M PRO
- That mainboard has USB3 but is seen as USB2 due to not using nonfree firmwares for it in Coreboot.
- Coreboot 4.10 without nonfree firmwares or microcode beside the builtin SMU firmware or the GPU video BIOS that comes from the GPU.
- Parabola x86_64
It might be related to
- USB timings
- The fact that the coreboot port is unfinished on the F2A85M-PRO
- The fact that the nonfree firmware/fpga binary for the USB3 on the F2A85M-PRO weren't used.
