CWM-recovery + root

I went on the links from the SW.banner Marauders of Acer-and branches in search of solutions for the BIOS, and returned with the CWM: D
Instructions in English
Instructions in Russian
If all drivers are installed correctly but the PC does not see the tablet - enter it manually into fastboot mode and should help

To get Ruth, first copy the file from the Root on the inside or the outside of the stick. Then install CWM and flash out the archive:
Attached fileUPDATE-SuperSU-v2.40.zip(3.82 MB)

Attention: This is a temporary rekaveri - after reboot will be back stock (ie, if you need the CWM again, to fleshanut any file with as root, custom firmware or restore a backup, you must do the whole procedure again).
Choosing T3 option. Folder tool is better to lay down the root of drive C.
In the menu, navigate using the Volume rocker. Choosing confirm button ON
Archive with Ruth sews! (Ie rutovanye firmware are no longer needed - updates over the air and get Ruth this way)
Nandroid backup on the outer-flash drive makes and restores too!
Backup do just on the outside of the stick - the seventh option from the top down "backup to external sdcard". If done on the inside, ClockworkMod folder is empty and remove it to free up 3 gigabytes on a flash drive, you can only CWM menu option delete
Plus this rekaveri that it can run on devices with bootloader zalochenny


Download (new version now backup and core with rekaveri):

For those who want to collect pure android in system.img

Kernel assembly manual

How to assemble our kernel:
Detailed - construct android Г— 86
The compiler (for me this is going - others have not tried it):
Download
I used Ubuntu 12.04. Also on the system must be installed Java implementation of Oracle
Installing additional dependencies for Ubuntu 12.04:
sudo -i
apt-get update
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev: i386 x11proto-core-dev \
libx11-dev: i386 libreadline6-dev: i386 libgl1-mesa-glx: i386 \
libgl1-mesa-dev g ++ - multilib mingw32 openjdk-6-jdk tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev: i386

Set symlink to resolve a name conflict:
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

Kernel sources are in the hidden folder.fr-AF68aK / YOGA_Tablet2_830L (ROW) _source_code / linux / kernel

830L Config folder: arch / x86 / configs /YT2_8_row_lte_diffconfig
Or pick up the config command in the terminal (see the readme):
cat arch / x86 / configs / i386_byt_defconfig arch / x86 / configs / YT2_8_row_lte_diffconfig>.config

ATmake file (line 196) you need to set the path to the compiler, I have this:
CROSS_COMPILE? =/ Home / fan / papka / build_kernel /linux-x86_64 / bin / i686-linux-android-
And fire! ie make
After building the kernel (make clean modules do not be lost anyway) go search for the folder with the source for the presence of.ko (If vayfay, modem, etc will not work - replace the necessary skompelirovanye ramdisk kernel modules - directory lib / modules )
How to flash the kernel to bypass zalochenny bottles and signature verification? Almost found ..

So as if the flash firmware on 13-inch junior series of yoga-enabled mobile !! ??
zorralex @ 19.01.2015, 20:46*
In versions with a smaller diagonal of firmware settings have mobile - I have asked, whether it is possible to flash 13-inch Yoga firmware from the younger model. Maybe someone tried to run and got an external modem?
Do not try to sew on the device firmware from another model !!! : D explains why dropped from the topic ..
intonation
In early December, has bothered to put up with the backlight samovolnichestvom, podtuplivayuschim interface and lack of prospects on the horizon .. Decided to explore Linux already and go through the firmware, select the partition on hard under of Ubuntu, all prepared and ......... laptop refused to boot from a bootable stick: lol: "Well, is not destiny" - thought and fleshanul full (yes, full) firmware from the 13 'th version.
- What for? To (maybe) to see whether there is the same glitches on other versions, and see where his feet are growing in trouble.
- What was the result? The device started to think that has a QHD-resolution display and will be scaled accordingly everything (even the bottles and rekaveri), so that the interface is not part of the visible area of ​​the matrix. Well at least the sensor calibration was not shot down - picked "by tapping the map" screenshots on the network.
- So what's the catch? Bring it was. And here is the main plugging.Device stops responding ports (USB and memory card), respectively, in any way (no contact at all) had not seen a computer, via an external connection recovery has become impossible.
Transition
Next, after a week of unsuccessful attempts to do anything, and another week nothing at all with him did not work, which gave to the service of the DSP (ITT group company, the Lenovo Certified Partner). The technician took to try to solve the problem on its own and in parallel to try to organize a replacement under warranty.
Gone holidays and month of time, warranty replacement was denied because It operates only within the country of purchase (I have from Germany). It remains only to pick up with nothing.
The experience of this situation
The only chance of salvation is that the firmware of the 13 'took the first version of the Lenovo is not the original, but to rebuild from Ruthpro100gamer 'and. And now the guide (who suddenly happen) how to act, if the tablet computer stopped seeing:
1) Take the following from the firmware files for your modifications:
a) boot / boot in a droidboot.img;
b) recovery / rekaveri as recovery.img;
a) kernel / core in the form boot.img;
2) Fill the files somewhere on the exchanger (I used Yandex.Disk, because it gives a fairly short links and the button "Download" page is not hidden by a bunch of banners);
3) to achieve the Internet connection on your tablet (I had to remove the protection on a key on the router to do without any input from the resolution of the downed interface);
4) Download the all 3 files, saved in / sdcard / Download default;
5) Take the programAndroid Terminal EmulatorYou can throw a similarly through the exchanger;
6) Further, trying to drive
su
Ruth and allow access, and then the team,who told SW.pro100gamer , and more specifically:
* Sew the core
dd if = / sdcard / Download / boot.img of = / dev / block / mmcblk0p3

* Sew rekaveri
dd if = / sdcard / Download / recovery.img of = / dev / block / mmcblk0p4

* Sew bottles
dd if = / sdcard / Download / droidboot.img of = / dev / block / mmcblk0p5

7) To check off and loads in the flashing mode (Power hold up volume +);
8) is connected to the computer and all firmware reflash entirely using the Phone Flash Tool.

Blame for such a long statement. : Grabli: If the material will be unclaimed, curators moderators deleted at any time.

P.S .: ROW-flashed firmware version on November 5, 2014, OTA booted on January 5, 2015. The Auto Brightness sort pofiksili, checked only on application Recorder - brightness is not changed when you run, regardless of the use of the light sensor. More did not climb, as already acquired Tab S for the new year and to part with his screen there is no desire.
