Firmware A07850

I bring to your notice that I do not own A07850, and I don’t have it either, so that I can figure out what and how!
And therefore I ask for fewer questions about the tablet A07850! I got the firmware, for which you can say thank you)

Read the instructions for the firmware, since tablets A and C have different processors (RockChip and MediaTech), respectively, different firmware methods!
According to the representative of HALLO, the priority for firmware, firmware v2

Firmware A07850 - Detailed instructions for flashing

Everything you do, you do at your own peril and risk! The author of the topic does not bear any responsibility!
Well this is so for your information, if in each sho

Preloader for a not needed !!!
Download RKBatchTool and extract from the archive (preferably to the root of the disk).
Turn off the tablet (by long pressing the power button and selecting the appropriate option when a message appears).
Connect the USB cable directly to the rear ports of the computer, bypassing any hubs and extension cords. It is also better not to connect to the front ports of the system unit. If there is a better-quality micro USB cable, use it better.
Connect the other end of the cable to the tablet while holding the volume up button on it.
In Windows, you will be prompted to install a driver for the new device. The drivers are in the folder RKBatchTool \ RockusbDriver \, select the appropriate one for your version of Windows and install. If something goes wrong, you can install the driver manually by right-clicking on the desired inf-file and selecting the "Install" option.
Unzip the selected firmware and transfer the only img file with it to the folder to RKBatchTool.
Be sure to disable all antiviruses and unload unnecessary programs.
Run RKBatchTool.exe. If everything is in order, the driver is installed correctly, then the digit "1" in the Connected Devices field should be green. Click on the "..." button opposite the FW Path field and select the firmware file.
Click the Upgrade button (second from the bottom) and wait for the completion message. The firmware takes an average of 5 minutes.

I share my experience) I have a SUPRA M846G tablet, the firmware in it was from a Pixus Touch 7.85 3G tablet. The problem was in the motherboard with the charge controller could not charge the battery 1% charged in an hour. I decided not to bathe and bought another motherboard, but it was from the Nomi C07850 tablet. When I installed it, there was a problem with the image it was completely gray, then I thought that the firmware should solve the issue. So it was, I asked the tablet with this firmwarehttps://cloud.mail.ru/public/DpDa/731ZVqbqgAfter the firmware image appeared, but when the charging was connected, a battery with a normal image appeared and after 5 seconds artifacts on the screen and hang. Then again he flashed it with the same firmware only the preloader threw from this firmwarehttps://yadi.sk/d/mNxvQdRjgezeXIt is from the tablet Nomi C07850.
P.S. The boards were different revisions on my tablet labeling on the board ELINK_MR790_V2 and on the board that I bought ELINK_MR790_V4 everything works fine, even Imei did not have to be restored. I was stitching it in different ways and with different firmwares until the idea came up with a combination of two firmwares.

How this nonsense nomi a7850 stitch on a rockship pc does not see it; firewood is not set up. I tried to upload the firmware to the sd card using the rockchip create upgrate program like and put it in, insert the memory card into the tablet, run it and not shit it is not sewn, clamped and reset not shit

[EzhenAce]

bars00707,

I will explain for those who are in the tank. The sd firmware tool is installed on the PC and then you insert the SD card into the PC (I will not explain the ways), this program is of the RUFUS type (I think everyone knows it) in it you specify the path to the card, the path to the firmware and it will do everything by formatting the card then turn off the tablet, insert a card into it (I won’t write the ways :), turn on the tablet and it will do everything SAMA will install the firmware even better than any advanced COLLECTOR, if she suddenly noticed that there is even the slightest failure, the installation will be immediately terminated will be ROLLBACK
