this happened to me, i had to throw android 6 roms at it untill one finally booted, i suspect it did somting funky to thr partitions maybe, not sureThanks for the great work.
I have a question: These 3 roms are with twrp installed and pree-rooted? If so it could be a problem for me, as I use AlexElec from sd card and apparently twrp does not allow booting from sd.
My device is Mxq s905x 1 / 8gb (I think it's a clone); the box is all black and with only the writing "MXQ" on the top.
Thanks so much
edit: I tried to flash the 3 roms, but you can't install any of the three roms, it returns an error at 4%. I also tried the alternate version (post # 355), but to no avail. Also now android 6 stock does not start anymore, the "s905x" logo remains fixed. Fortunately I can start the AlexElec 3.3.1 version via sd
Tomorrow I will post some pictures of the mainboard, maybe someone can give me some advice. Thank you
