Lots of complaints, but a real lack of details
I have a guess, but 1st, some information for you
Except for cell phone, arm is a newish computing technology
Sure, there have been SBC, usually not that powerful to do complex things
And rPi, has a vendor supplied binary blob, video + bios
You know, I hope, that all x86 have a bios, that does low level management of hardware?
If you update with WRONG bios, usually(nearly always) computer ends up in trash
idbloader + uboot + ATF is equivelant to bios, humor me, when I say bios I mean uboot+
I have found, by experiment (and bad luck) that if you try to boot with wrong bios,
the pbp appears dead, only charging led. Also, if there is NO bios also dead
So, I bet that there was something on the 128, but wrong
Recovery is,,1) remove bad bios (recently found this essential)
2) if bad bios on emmc, disable 3) put good, bootable SD card in
4) extra long press (pwr button,20+s) 5) normal start, 1s press
6) try a second time, hold longer 7) try a different good card
That it remembers is, I think, because there is a battery
OR, perhaps you have emmc disable switch wrong?
When they say enable, they mean shorted = emmc disabled ,, this is a bad description
To troubleshoot, always simplify as much as you can, then add until it breaks
So, no emmc, only good SD, maybe extra long press
Questions:
Do you have emmc carrier/dongle?
Did you write something on 128? What?
What was on the 64?
What did you expect for $200, you certainly got fairly nice hardware for that
