I have described everything in general. I assume that many things are obvious to you, but maybe someone else will want to use it, so it will explain what he is doing and what is going on 0
Unfortunately, I do not have pictures or screenshots at my disposal now, so a text description must suffice ...
Subject of operation: Tablet KIANO Slimtab 7 3GR It will probably also work on the other Slimtab XGR editions. It is important to have "3GR", because there are also "3G" versions and that's something else.
A warning first: - you do everything at your own risk. It does not guarantee that everything will be as described here, because each hardware may behave differently and even have a slightly different version of the software.
- rooting the equipment is tantamount to loss of warranty,
- while rooting the tablet may be, or even rather, will be completely wiped, so if you have any files or settings on it, make a copy of yourself
-
after rooting, tablet may not start properly. Symptoms: After switching on, the KIANO logo will appear (blink) and you will see a few red, green lines, as if filled squares with text. It is not known, maybe something can be turned off so that it does not appear, but the tablet will stand on this screen.
Pressing VOL- will refresh this screen, but clicking VOL- will take us to the fastboot (green carpet).
However, to launch the tablet on this screen immediately after turning it on, press VOL +. He should go on without helping him.
I do not know if it is some kind of security or what, but after rooting there are such symptoms (I had this on 4 tablets). Its Chuwi Vi7 counterpart has the same.
0. Basic applications adb-ver-root.zip - ADB with disable-verity option - not every ADB has this. ADB with all files for root
kiano-st73gr-adb-drivers.zip - tablet USB drivers - if it doesn't work, run the package below with a plus
kiano-st73gr-adb-drivers + .zip
1. Unlock the bootloader A. To unlock the bootloader, you must first access the developer settings. We do this in:
About tablet >>Build number .
Click on this field several times (7) until the information that we are a programmer appears.
B. Then, near the information about the tablet, the option "
Developer options "and we go in there
C. We turn on "
USB debugging ", turn off options"
Verify applications via USB ".
And very important - we enable the option "
OEM lock photo ". In twin models this option may not exist, so then it should be omitted. In KIANO Slimtab 7 3GR there is and it must be turned on.
2. Then connect the tablet to the computer. We check if we have all the drivers (in the device manager there should be no exclamation mark next to the device).
We run ADB. We unpack the file
adb-ver-root.zip and after unpacking, go to this directory, hold SHIFT and click the right mouse button. A context menu will appear with an option and the message "
Open a command window here ".
We enter in it:
When the tablet restarts, wait about 30 seconds and enter further:
fastboot oem unlock or if we want to approve immediately:
Some message may appear here, probably confirmation. I had it once, not once. Then I clicked VOL + / VOL- and he kept going.
After entering:
it should appear:
Device: unlocked 3. We clean the cache - otherwise the tablet may not start or it will turn on with a lot of errors:
WARNING! At this point, we clean up all the data we had on the tablet.
4A. NOTE - here we should upload recovery. I have working, but there is a problem or security feature with this tablet. In recovery and fastboot mode, the screen displays red, green stripes, as if painted bars with text, fastboot mode is also completely green, as if a rug on the screen, as if the screen did not have an adjusted resolution. This happens in every Kiano Slimtab, even when taken out of the box.
However, I omit this stage, because even if we upload them, it will not help us, because we will not see anything. For example, in TWRP we could use a special package and simply continue to root the hardware or make copies. Unfortunately, we won't see anything.
4B. We start the tablet normally, until it loads (without any mode, only USB debugging should be enabled) and enter:
We wait about 30 seconds for it to start. As if it did not start because the screen error described above appeared, you should help him.
5. Then we run:
then enter:
After reboot, it should update 2-3 applications and root is ready. We can check it with the RootCheck application installed on the tablet or any other application.
If there are any problems, write.
You don't need to flash an older Android to root tablet 0
And the problem with the battery, maybe it's a bigger problem, because for me it can withstand several days in standby mode (although it is still working). I have 2 models and let's say a twin (Teclast) which is slaughtered by my daughter. Only he does not have a radio but has a Dual SIM.
Good luck!
