Huawei MediaPad T1 S8-701u/S8-701w bootloder unlock TWRP recovery ROOT

iodak · Jan 14, 2015

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/0B7RlBIN4xO50RUxqU1E2ZGJmRUk/view?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://d-h.st/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/0B7RlBIN4xO50QlFVSFZkWlhRX2c/view?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://xdaforums.com/showthread.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://d-h.st/in71 (stock recovery)

Code:

fastboot flash recovery stockrecovery.img

To ROOT flash http://download.chainfire.eu/supersu in recovery

Recovery: newest TWRP http://d-h.st/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!

Couldn't be better timing. Just received my 701w unit (Iskon HR)

Hi,
I did everything according to the instructions, but cannot enter the Custom Recovery. :crying:
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.

it Works

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 ... :laugh::good:

Thanks for the info. I updated first post with more info on how to resolve issue if stuck in bootloader, unable to boot to recovery!

iodak · Jan 14, 2015

Now that we are unlocked we should make some presure (send emails) to Huawei to release kernel source!

matekhr · Jan 15, 2015

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.

iodak · Jan 15, 2015

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.

I installed Busybox after I turned off "Mount namespace separation" in SuperSu

---------- Post added at 05:16 PM ---------- Previous post was at 05:04 PM ----------

there was a problem: as soon as I push cable in tablet, from the charger or computer, tablet turn on, although previously it was switched off. Now I can not recharge when tablet is switched off, just when he is turned on...

iodak · Jan 15, 2015

I didn't do offline charging. I will see what i can do. That is not really a problem.

The truth is, this is not a problem, but it is unusual ...

Same here.Im unable to load recovery unless i use ADB command on PC???
Any help?

iodak · Jan 17, 2015

Vol down when powering on will get you to recovery.

Also in terminal emulator app
su
reboot recovery

darko150 · Jan 17, 2015

I have to hold the buttons Power and Vol- right up to the moment when it appears Huawei logo. Then go into TWRP Recovery.
If I let a moment sooner or later, can not enter the recovery.
Although there are small imperfections, I'm very satisfied, thanks IODAK :good:

gogy3d · Jan 17, 2015

I use https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot&hl=hr quickboot to go in recovery.App needs root.
Or use standard procedure hold vol- power on...
Who knows when is build custom rom for S8-701W?
