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
V1 Firmware -download
Firmware V2 -download

Firmware C07850

Compatibility of firmware and touchscreens

Official firmware

V1 firmware- Official firmware from hello -download
V2 firmware- I did everything right, but does a white screen start up? No problem! try this firmware (v2) -download
Route on these firmware can be set without problems!

Modified firmware C07850

[color = blue]Modified firmware (Internal memory 4.37Gb, USB Drive 1.18Gb):
V1 firmware - (Download)
V2 firmware - (Download)

I can not put Ruth on these firmware, I solve the problem ...
(Root can not be put after redevelopment, I think how to fix it)
Solved a problem,First, we flash the firmware with the redesigned one, then put the root through kingo root and flash the boot (if you want you can still recover)

Before the firmware, watch the spoiler "Instructions" for sure!

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.

Good day! On the tablet is the processor MT8312, and the firmware is specified percent MT6582, the tablet will not die from such a mismatch?

[madrid1985]

I asked for the tablet, the tablet does not turn on and does not see the computer,

[qwerty12345554]

madrid1985,
This is a fake processor, I have everything okay and a few more guys. There is one firmware directly from the SC (I was thrown off so I could flash my tablet)

Posted 04/20/2015, 15:48:

madrid1985,
What firmware was stitched?

Posted 04/20/2015, 15:53:

madrid1985,
write in QMS, try to solve the problem

[madrid1985]

stitched with firmware that is specified above in this section, the one that is labeled "recommended"; after flashing, the screen lights up in blue seconds5 and goes out. In the device manager, when connected, shows the connected Linux device. I tried to flash it again with the same firmware — it doesn't even try to sew.

[qwerty12345554]

madrid1985,
try through Format all + download. If the firewood has risen to the norm, then the dispatcher should have a preloader

[Saturn_94]

Tell me please, has anyone already tried to swap memory, or to re-size Scatter as instructed? Everything really works. I'm afraid to screw up the firmware.

[qwerty12345554]

Saturn_94,
I tried )

[Saturn_94]

qwerty12345554,
As I understand it, everything went well with you.
Please tell me what to do with the files from the header (EBR1, EBR2, MBR) to increase the amount of internal memory. (Re-allocated Scatter).

[Saturn_94]

I tried to remap the memory, did not work. The drivers became normal, the program saw the tablet, but the operation ended with the error "PMT changed for the ROM; it must be downloaded."

[Saturn_94]

Tell me, but if you do a memory replacement, where does the usb drive change from micro sd, then the internal memory (for installing programs) remains the same (within 1 GB)? Only the cache can now be saved to micro sd. Do I understand correctly?
And how to expand the place to install the programs? I tried the method with the redistribution of memory, it did not work out, I described the error above.

[Andrii ovdiichuk]

In kogos bulo taka, scho after flashing firmware better display psdsvitka? And with the shiv of the firmware.

[kideap]

so taka situation itself tС–lki pС–dsvС–tka

[qwerty12345554]

andriyko92,
kideap,
I need another firmware, I will ask the SC. write your serials to me (S / N on the back of the tablet)

Posted 04/30/2015 23:45:

Saturn_94,
No, when flashing the re-sized scatter, the memory layout of the phone changes, Internal memory (for installing applications) becomes 4.37Gb, and USB Memory 1.18Gb. And with the boot.img firmware, the USB drive is switched to 1.18Gb with a microSD card.
That is, you have a 32 GB memory card, the internal memory (for installing applications) becomes 4.37Gb, USB 32GB drive, microSD 1.18Gb (the size can be made smaller, but if you make a backup to the SD card, you do not have enough space)

Posted 04/30/2015 23:50:

Saturn_94,
You need to flash EBR1, EBR2, MBR along with the boot, that is, insert the folder with the firmware with replacement EBR1, EBR2, MBR, boot, scatter (Downloaded earlier), and in the SP Flash Tool choose the scatter from the folder with the firmware.PURSE ONLY THROUGH FORMAT ALL + DOWNLOAD(Otherwise there will be an error "PMT changed for the ROM; it must be downloaded.")

Unsubscribed in the SC, they think they will answer ... Or they will be sent to 3 letters, or they will throw off the firmware)

Reason for editing: Unsubscribed in SC

[Saturn_94]

I tried to flash the re-allocated scatter, for some reason it did not give me. I now have internal memory - 0.98 GB, usb drive - 4.62 GB, micro sd 32 GB. Tell me, if I ask for boot.img that swaps memory, what result will I get?

Saturn_94,
You will have the Internal memory (for installing applications) to get 4.37Gb, USB 32GB drive, microSD 1.18Gb.
Replacing the memory card and USB drive + re-marking the memory of the tablet - You need to flash EBR1, EBR2, MBR along with the boot, that is, insert the folder with the firmware with the replacement of EBR1, EBR2, MBR, boot, scatter (downloaded earlier) and in SP Flash Tool choose scatter from the folder with the firmware. PUSH ONLY THROUGH FORMAT ALL + DOWNLOAD (Otherwise there will be an error "PMT changed for the ROM; it must be downloaded.")
If it doesn't work out, wait for the end of May days, I will record the video ...

That is, re-marking of memory is possible only with a full flashing of the device. But based on the fact that the firmware that has been laid out so far few people have approached, you will have to wait for the worker on our firmware device.

[qwerty12345554]

Saturn_94,
That's right, discard your serial number.

Tell me, how did you backup on your tablet? As I understand it, in the header it is from your tablet backup.
