Hello. It is Port/Driver problem.
Use cable with direct connection to motherboard, no hub and e.t.c.
Make HW reset on tablet - long hold PowerOn button ( up to 15 seconds ) with pressed VolUP and VolDown buttons. After - wait 15 seconds and connect phone with pressing before need operation button. If tablet have "Reset Button" - just press it once.

the problem was from the drivers.

Could I write firmware with CM2 in a MT8127 tablet with NAND CHIP?

There exists NAND MT8127?? O_o

******* SDTNQGAMA-008G is the nand IC from this tablet.

I have the firmware from the manufacturer but after flashing the tablet is dead.

Hm... Thanks for the log. I need find such tablet with NAND. Without it - can't say something yet. I've found one with eMMC with much luck.
Can you tell me model and any link, where is possible buy this sample? Or, if you can ship it to Russia or Dubai with any way and sell us - will be great.

decodari · 04-07-2015, 11:57

Qualcore 1010

decodari · 04-07-2015, 11:58

I'm sorry I can't send it to you because the tablet is from a customer.

decodari · 04-07-2015, 12:02

Becarefull because there are two tablets OVERMAX QUALCORE 1010. One with MTK CPU and one with ALLWINNER CPU.

Dzirt · 04-07-2015, 12:39

Strange. In device specifications mentioned 8GB eMMC memory... Is it exactly this device, or some ref?

decodari · 04-07-2015, 13:28

This device...we keep warranty for them.

Dzirt · 04-07-2015, 13:49

Thanks for info. I can try order it via BY ( country in offcial diler list have one seller ) but it can take up to 2 month

If you can help us with buy such device and send ( all taxes and e.t.c. will be payed too ) - maybe, can short time to 2-3 weeks.
