Tell me how to find out visually the AirTab M84G DNS revision. The tablet does not turn on, but it seems to be alive. I want to try to raise from the dedmod, if possible. need to know the revision number.
Hell knows already alive or not. The device does not turn on, charging hell knows, goes or not. On the screen, nothing. When I tried to flash through the flash drive, the error was "4001". When determining whether the tablet is off, firewood is set. How do I understand it is still necessary to supply firewood when the device is turned on? after the appearance of the 4001 error, USB is defined as unidentified until you remove the device along with firewood. There is no tester, so the hell knows where to dig from, either from hard or from a fallen OS.

I got a tablet dns ddr3, at first it did not turn on, just blinked the screen. The charge went and showed half the battery. I removed the back panel, disconnected the battery, waited and attached it back (tightly). As a result, the tablet turned on and works normally, but the battery does not charge. Shows what is on the charge, but the charge does not increase. What could be the problem?

Three options are the most possible:
1) Contact from microUSB to board (or vice connector) is broken.
2) Battery or its controller are tired
3) Tablet charging controller
Do all USB functions work?
Indirectly, the operation of the power controller can be viewed in Factory mode (power & volume-)

I started charging from the iPhone unit, but it was super slow) I need to feel the unit is more powerful or is it still carried to the service?

Or all the same to the service?

Well, then the question arises about the cost and profitability ...
My charge is much faster when it is turned off, if it is on, then only by killing the process "multimedia storage" which loads the processor by 80-95%.
And since the tracks from the USB connector were torn off or burned out, while I soldered the nozzles as I could, everything seems to work except OTG and it charges not so good (I sin on the charging controller). In general, I am waiting for the Explay fee from the 1st revision (I did not find the second one) from here:https://156led.ru/planshety/platy/explay

The other day I received a parcel with a fee, from the time of the order about 20 days. I changed, everything works. The board is of course with parsing, there is no visible damage, the microUSB connector was soldered. If it were not for the traces of the propayka, one could think that the new ... cameras and a WiFi antenna were included
And by the way, I noticed that it charges much better from such a cord with adapters:

If with a simple cord the charging current was rarely greater than 450mA, then with this it reaches ~ 750mAm
I'll add, the cable itself is harsh and short pretty
