Karoch got root rights B)

took everything from the above link,Italianco-owners of this unit)
If anyone needed, did this:
1. Download and install Flashtool V.5.1728
2. Download and install MTK_Driver_Auto_Installer_SP_Drivers_20160804
3. I downloaded and unzipped the official firmware 20171027_g20v57_c2k _kw_s81
4. I downloaded Recovery By Ghost45 (Test 1) (for which I thank him very much!) And sorted out
5. I downloaded and threw the archiver Root SuperSu Vers 2.82 into the root of the phone
6. I cut down the phone, picked up the firewood, again disconnected the bodies
7. In the folder where I unpacked the recovery, renamed recovery_Cwm_Touch_test1.img to recovery.img (no_touch tr tried, but TWRP did not start ...)
8. Launched Flashtool chose the one that was in the archive of the recovery in the scatter-loading file, clicked on the download and picked up the phone in the off state, a couple of seconds and the reciever was installed.
9. We unhook the bodies, hold the volume up and power, as the logo appeared, hold the volume up for another 3 seconds and cut the recovery (it's still raw, so upside down: D)
10. select "instal zip ...", further below, "... from ext sdcard" (like so ... forgot how exactly), a tree of internal phone flash appears, we find a previously cast archiver with Root SuperSu Vers 2.82, we wait for everything Down, and then we cut down the bodies or reboot.
11. go to the system see superSU, rejoice!
. I just returned the original recovery, the custom is still buggy yet
12. pulled the files preloader_g20v57c2k_kw_s81.bin and recovery.img from the archive from the official firmware and threw them with the replacement in the folder where the custom recovery lies and then do the same as when flashing the custom recovery
13. Everything, the phone has root rights, and original recovery.

Friends can not hear about the new firmware ??

And what's the point of putting recovery_mod_umi_S2? It is still raw, as they say here. Or without it the root will not be delivered?

Without it, the root will not be set ...) Dima16

Tell me, but if I throw the body to the factory settings, will I lose the root and recovery ??

belthazor1901,
Recovery is definitely not, (it is out of reach) and the root is probably (I have not tried it myself) according to the suta as all the programs on the body are demolished, you can carry everything through the recovery, in my opinion it would be better, you need to clear it, davik caches, and data

Not sure where you can read about the values ​​of all the checkboxes?

Lower userdata so that the data is not erased, and the upper so as not to kill the firmware ...
hiding skins under spoler, otherwise they will delete, and you save traffic to someone else who is not interested in this dubious person

Skin changed? And on this you sew one recovery, where the daw stands, the rest of the firmware files you do not sew ...
What exactly do you want to do with the body? There, in the princep I described everything in steps and screenshots in Photoshop circled in red

Misutka76,
I think to wait for the new firmware with the camera fixes and immediately flash it along with the root.
userdata is what data?
What does it mean to kill the firmware? Are there any positive moments from this tick?

szi5un
I think I'll wait for a long time, so long as the last one is V1.0 2017.11.23 - Android 6.0.1, when you sew it without daws, it turns out like an OTA update, all your programs, contacts, notes there, launcher, etc. (in short, everything) remains, but the update (patch) is put
And with one daw it is you sew the recovery, for the root without affecting the firmware

Misutka76,
And if I want to leave only contacts, and all the programs to demolish? And after installing the root, how can you put your own recovery?
The firmware was promised to be released in a month after the release of the last firmware.

Then put the bottom daw with the firmware usedata, and you’ll take it all down, save your Google contacts, and it’s easy to return the recovery; stitching, but why does native recovery stupid and just not needed, cwm and twrp can do something and help with copying

Misutka76,
New versions of non-curved recovery when expected? Who makes them?

szi5un
I don’t know this ... I know that twrp needs to be ordered, one person does onsavagemessiahzine.com, there is a theme, but he needs some files from our system’s phone

And let's give him all the files, let him collect the firmware for us!
