[Huawei MediaPad M2] manowar666:
Thank you both for replying!

Unfortunately, I don’t have an unlock code. I have contacted Huawei through https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail months ago asking them for an unlock code for the bootloader but I never got a reply. I have even tried again a couple of months ago but they didn’t answer back. It seems there is a limitation on the time entitled to ask for an unlock code – I believe 3 or 6 months if I remember correctly.

I have just tried contacting them again through an e-mail form, let’s hope this time they’ll reply.

Now please allow me to fill you up in some more test/trials I did today:

I issued the “fastboot oem get-bootinfo command” and the result is this:

(bootloader) unlocked

OKAY [ -0.000s]

finished. total time: -0.000s

(Not even a milisecond in replying. This looks a bit suspicious, right?)

But when I try to continue as per your instructions (i.e. issue the command “fastboot erase recovery”) this is what I get:

erasing 'recovery'...

FAILED (remote: Command not allowed)

finished. total time: -0.000s

So I cannot go on using your suggestions :(

I have also tried to use DC-Unlocker to unlock the bootloader (perhaps wasted money since the bootloader is already unlocked but I just wanted to try). When I bought the credits and opened DC Unlocker Client, the option for Unlock was grayed out, but the option for Factory Reset Protection was selectable. Based on this, I am now suspecting that the tablet has got FRP protection enabled, since I did have a PIN set-up before choosing the wrong model in TWRP manager and brick it. So I tried DC Unlocker’s Factory Reset Protection (paid 15 wasted euros!) but again no luck. This is the log from that attempt:

Since I already paid the €15 at DC Unlocker I decided to give a go using their other piece of software, DC Phoenix. This one allowed me to flash pieces of the UPDATE.app package while in fastboot mode, without complaining about locks. It seemed to be flasing normally (I tried flashing all contents of the latest UPDATE.app package) and then (as per DC’s instructions) I tried re-flashing everything using the second option (Upgrade Mode) while in Repair mode (i.e. Vol +/- pressed while powering the tablet).

No success either – Tried various combination of DC Phoenix – even only the files you suggested (BOOT & RECOVERY, BOOT & RECOVERY & USERDATA & SYSTEM).

Is there a way to find out if FRP has been activated through fastboot? Tried Googling it but no usable results came up.

Any other suggestions would really, really be appreciated!
