[Huawei MediaPad T5 Questions & Answers] Rockel:
I'm home (finally)...

If the steps mentioned above didn't worked out, I would like to ask you to do axactly as I did. Just unlocked my Mediapad T5 just 1 month ago or so, so everything I've used should be recent enough I guess.

First:

- Un-install your potato version.

- Un-install your Mediapad T5 USB drivers.

So we can begin from scratch

Also:

- turn on OEM-unlock and USB-debugmode in developer settings.

I asume you have a decent and working ADB version installed on your PC?

If not, or when you're not sure, uninstall it too.

I was using the Minimal ADB and Fastboot from here:

[TOOL]Minimal ADB and Fastboot [2-9-18]

Introduction ADB and Fastboot are arguably two of the most indispensable tools used when working with Android devices. If you really want to modify, debug, and tweak along with their countless uses in rooting, and other procedures ADB and...

Then:

1) Install the Huawei USB drivers from here:

Support area | files.dc-unlocker.com

(this) or (this) are the "official" sites I got this from.

2) Install the latest version of PotatoNV from here:

Unlock bootloader of Huawei devices on Kirin 960/95x/65x/620 - mashed-potatoes/PotatoNV

Open potatoNV and use these settings marked in red:

3) Plug the USB-cable into your PC already, but don't connect the other side to the tablet. And make sure your tablet is turned off.

4) Now short the testingpoint with a shielded part. I just used a thick copper wire and used it between testingpoint and metalshield just next to it. Metal pliers as used in your video should work too ofcourse.

P.S. I see that you also disconnected your screen in the video? It seems that it's verry important not to see a charging icon in the next step, so maybe it's better to connect it again for this step.

5) While still shorting the testingpoint with the shield, connect the USB cable to your tablet and be sure no charging icon pops up (This can be a bit difficult doing on your own. Easiest way is to have someone around te help in this step). After a few secconds when connected (without seeing an charging icon) remove the shorting between testingpoint and shield.

6) Make sure that the Huawei USB COM is selected in PotatoNV (and that the other settings are the same as the screenshot)

7) And pres "Start!"

8) You should get similar results now:

p.s. In your video it seemed your device got disconnected somehow while uploading. You should not see that "timeout" message here now annymore.

9) Make a screenshot of your results, copy them to a text file or write down at least your "new unlock code"

So you won't have to open your tablet annymore in the future. You can use this newly obtained unlock code now to lock and unlock your tablet without opening again.

10) You should now see a warning screen everytime you reboot the tab. It warns you about that the device can't be trusted annymore because of the unlocked bootloader.

You can also enter Fastboot to check it

Fastboot/ Bootloader mode:

1. Turn off the device by holding the Power key for a few seconds.

2. Connect tablet to PC/laptop using the USB-cable.

3. Hold down Volume-Down.

4. Hold down the Power button until device starts (while still holding Volume-Down and USB connected).

4. Tablet boots now into Fastboot-mode.

You should see the following screen then (pay attention on the 2 red lines at the bottom):

You can close your tablet now!
