Problems with installing H3Droid on an Orange Pi Zero v1.5 #4

I have two kinds of problems with installing with FEL. The first one is never getting the script to end, it is stuck at Android Debug Bridge: The second one being "ERROR: no nbd callback, probably ADB did not call board with success, please retry"

The board is flashing rapidly two reds, two greens

Thanks for reporting ! Only some orange pi zero models support FEL installer and may need an older kernel, tests were only made on early v1.0 256MiB models provided by Xunlong and still installation was known to almost always fail if not using dram heatsinks. Some users had success with 512MiB v1.0 too but after multiple try ( dram heatsink again ?).

My original guess is still that both FEL installer and H3Droid installer put too much stress on the board and crash because of faulty thermal design (v1) that spreads cpu heat to dram.

You may get more info by using serial debug https://h3droid.com/blog/uart-cable

If h3droid installer can complete normally then it could be a bug and possible to fix it but i don't have access to v1.5 actually.

Thanks a lot for taking the time to give a detailed answer. I will definitely use UART to see what's going on.
