Hi!
This is for Huawei Mediapad T1 S8-701w/u aka Mediapad T1 Honor.
As we all know this device has LOCKED bootloader and it is not rootable (only russsia firmware for s8-701u is)!
I am not responsible for bricks so procede at your own risk!
Read whole process before you begin.

First backup everything including internal SDcard!

1) This process will install factory unlocked ROM with just basic testing apps you will loose your curent ROM( we will return it on step 3)
Download: https://drive.google.com/file/d/0B7R...ew?usp=sharing
Extract and copy dload folder do root of your removable sdcard (external sdcard)
Power off device
Hold volume down and turn on device
Wait till install process is done and device is booted again
2) Install custom TWRP recovery
Connect device to computer (ADB, fastboot needed and drivers installed)
Download recovery.img from http://devhost.xda-developers.com/saW and copy to same folder with adb and fastboot
Type:
Code:
adb reboot bootloader
Once you are in bootloader (huawei logo) :
Code:
fasboot flash recovery recovery2.img
When done reboot (hold power button) or:
Code:
fastboot reboot
3) Now lets recover our original ROM:
Download rom for your device ( 701u or 701w)
Here are some links:

Here is western europe images for S8-701w I use this one
It is the best available firmware for 701w (also multilanguage)https://drive.google.com/file/d/0B7R...ew?usp=sharing

I can provide more firmwares but i have slow upload speed so I ask for someone here who can reupload them. I will send him link to inbox (limited download).
Extract UPDATE.app from firmware
Download Huawei extractor (windows tool)
http://forum.xda-developers.com/show....php?t=2433454
Open UPDATE.app with Huawei update extractor and extract SYSTEM.img and CUST.img (right click on images)
Copy SYSTEM.img and CUST.img to your fastboot folder
Reboot to bootloader
Code:
adb reboot bootloader
Once you are in bootloader (huawei logo) :
Code:
fasboot flash system SYSTEM.img
fasboot flash cust CUST.img
Turn device off and boot to recovery (hold vol down and turn on)
In recovery: Factory reset (format /data) and reboot.
Done!!

If you get stuck in bootloder unable to boot in recovery:
flash and boot into stock recovery to clear bootloder flag
then you can flash TWRP again
Here it is:http://devhost.xda-developers.com/in71 (stock recovery)
Code:
fastboot flash recovery stockrecovery.img
To ROOT flash http://download.chainfire.eu/supersu in recovery

Recovery: newest TWRP http://devhost.xda-developers.com/saW
BUGS:

Internal sdcard is mounted to /data/media, while on device /storage/emulated so use external SDcard.
Also because of wrong mounts when you do wipe it will delete everything on internal SDcard (only /data/media will stay)
TOUCH dont work when booted: just wait till screen off timeout (10s), then press power to turn screen on it will work now


Sorry for bad english!

Hi,
I did everything according to the instructions, but cannot enter the Custom Recovery.
I tried and CWM and TWRP.
ADB Tool shows that all goes well, but when I press any combination of buttons to enter the Recovery, Tablet enters in the bootloader ...
Now cannot install a different ROM, because it does not start Stock Recovery to initiate dload, it enters the bootloader and standing there.
Do you have any idea what to do ...?


Edit: From Now as soon as plug the USB cable Tablet lights up ...

Edit: Nothing deleted on the internal SD card... Still I can see my old files

Can you explain what did you did last? Recovery, system, and cust images are flashed with fastboot in bootloader mode. There is only twrp recovery image here to download.

Thank you very much for your help in PM. With this Recovery2 in Post #2, Tablet works beautifully, and the entire process is quick and easy.
Root and TWRP Recovery I have, I can adjust the rest ...

It would be interesting to see is it somehow possible to flash 701w with 701u FW, because as I can see on my tablet, it seems that SIM connector is here, but filled with some kind of rubber sponge material.

It is posibble. Just use system and cust images from u version. I am not sure if the sim connector is in. Cant get that sponge out.

Edit: that factory unlocked update.app is from u version anyway

Edit2 I think that all roms are similar they just disabled some stuff for wifi version with config files.
like /cust/channel/*/prop/local.prop
ro.config.wifi.only=true

Is there any link to see how to disassemble this tablet?
It would be much easier to put the sponge out with removed back plate.
