    After touchscreen issue, I want to fix that problem but i've install then a old Cube U30GT2 firmware (V2.03), but maybe different loader version, It has brick my tab.

    I've try open them and shortcut the tab to enter into "Mask rom flash mode" (blue color?)
    but without success. try 2 short circuit point but not reaction..
    tabinfo:

    If I´m wrong correct me, but should you not first short the PINs, then connect to USB and Erase the Nand completely. Then use RESTORE to flash it ?!
    As it has 2 NAND, normally one of them should work to short.
    7+8 sometimes also 8+9...

    I remember a User of Freaktab does this to a Stick and he uses BOBs Flash Tool to ERASE IDB in maskrom Mode.

    The unbrick is already done, it was the first pin left near gnd,tx,rx with short-circuit it will enter mask rom flash mode, but after restore, the touch issue is still exists.. maybe just a faulty touchscreen and right on the time on my flash?

    Ok, cool. Btw... my Chuwi runs now for about 6hrs, 33min. and my Battery is about 87% now. All the Time WiFi is on. Think OMA has set this to ON also at Sleep. But I think this is ok. If I need WiFi off, I personally love to do that manually.
