How to enter it in rekoveri?

[n-bear]

1. Press the power button
2. Start counting.
3. After a second, but before the screen saver appears, press Volume +
We count once and press Volume +
4. A logo appears, you can release the power button, but keep the Volume +
We count two-and-three-and-four-and five-and-six-and-seven
5. When the recovery screensaver appears, release Volume +.
Start work in recovery.

Try the same thing, but with the "-" button. What will appear on the screen?

Does a desktop or unlock screen appear during normal boot?

But interesting: atTytsThe firmware hangs on the tablet, but it seems to me that it should not be a single * .pac file?

Here by the button "-" and rekoveri appears

Standard is exactly that, but I prefer to do the firmware package differently.
If necessary, you can use this .PAC file,
opening it in UpdateDownload (you can takehere), and running the firmware. Video instructions -here.
Are the drivers for the firmware installed? What is the OS on the computer?

[dashnikd13]

Win7 64, went like a firmware, but in the middle it failed and that's it, a brick. Can I do something?
The tablet does not respond either, charging does not go.

[n-bear]

The contents of the line with the word "Failed" can be found?
Try re-firmware (I had this).
The battery is not removable - there should be a "Reset" button.
How do you enter the firmware mode?

[dashnikd13]

Something about time, I enter the mode by "-".

[n-bear]

Clamp "-", connect the cable, poke "reset"?
Optima 10.8 and Optima 10.7 - never relatives.

By the way, are you registered with ddixlab?

Copy! You know everything turned out with a "reset"! It seems to be alive.

In the course, of course, there and took the firmware.

[n-bear]

And now quickly lay out the table of contents of the folder where .PAC was unpacked.
Or then I download .pac myself, then deploy it and make a normal firmware kit.
Here is suchthat under the blue spoiler. Naturally, the folder for the firmware files is calledOptima104.
Pictures lookhere.

And now I'm very interested in the file./system/build.prop
Specifically, these lines:

ro.build.description=q801-user 4.4.2 KOT49H eng.xnq.1414721398 test-keys
ro.build.fingerprint=alps/q801/q801:4.4.2/KOT49H/1414721398:user/test-keys download

On the subject of whether it takes the recovery updates of their own making.
Typethese.
In particular, the installation of root-rights managers.
But, most likely, you will have to patch the factory recovery. Then flash it separately.

And now quickly lay out the table of contents of the folder where .PAC was unpacked.

You mean on a computer, then C: \ ResearchDownload_R2.9.9005

[n-bear]

I need a similar picture

Well, or just a list of files.
Yes, and the file with the .XML extension is better to archive and attach to the response message.

[dashnikd13]

This is how to look at such a list, in the sense of what? But the .XML file was not there, the file was one in the archive.

[n-bear]

When you open the .pac of the ResearchDownloader file, it is unpacked into a temporary folder.
Here is its contents and it is desirable to copy somewhere.
Then it will all be the contents of the folder.Optima104. Multiple .bin and .img files.
There will also be an .XML file.
I have now created a temporary folder for XP created along this path:
C: \ Documents and Settings \ NB \ Local Settings \ Temp \ _DownloadFiles6816515
You can simply search for a folder named starting with_DownloadFiles.
Connecting the tablet is optional.

Here is the result of the dir command in this folder:

27.02.2016 23:18 <DIR> .

SC7731_UMS.xml - the file you are looking for.

[dashnikd13]

Made, everything lies in a separate folder. The XML file is attached.

Cool markup of memory - under the system only 600 MB.
I have on smarts - from 980 to 1600 MB.
And here is the .PAC downloaded. I deployed, I am preparing a package for the following firmware.
Ready, you can take ----------->Optima_RD_Flash.rar(734.96 KB)


On drive C: create an RD folder, unzip this archive into it.
To folderOptima104put all files (17 pieces, except for .XML),
those on the picture in your post.
I hope you copied them somewhere, after receiving the picture.

Run ResearchDownload.exe.
Press the button with two gears.

I got this picture

The Main Page tab, for the rest there is nothing to do.

Checkboxes marked ALL sections.
To reflash only the recovery, you must remove the checkmarks from all sections (Select all files)
except the one next to Recovery, with FDL1 and FDL2 required for firmware
(non-selectable checkboxes) are the agents of the RD program and they are loaded into RAM.
At the end, click "OK". If you do not need to change anything - close the window with a cross.

Congratulations! Patching recovery is not necessary.

ro.build.description = scx35_sp7731gea_k03_cfgj_64_4plus_dt-user 4.4.2 KOT49H 14B__201509182254test-keys
ro.build.fingerprint = DIGMA / scx35_sp7731gea_k03_cfgj_64_4plus_dt / scx35_sp7731gea_k03_cfgj_64_4: 4.4.2 / KOT49H / _201509182254: user /test-keys

You can immediately install updates to get the root.
From herequite fit.
Yes, at least this one -get_root_v1_0_signed.zip
And the text_signedfor your recovery is required.
Says that the archive is signed. Archives without a signature accept other recovery (custom).

Thank you so much for such work! Probably not for me alone, this is useful.
