Hi.
Did anyone succeed unlock Mediapad T3 7 bootloader ?
I have model BG2-W09 wifi only (European version). I have problem get product id
which is necessary part for bootloader unlock on Huawei site. Stucked to the calculator thing,
when i'll enter ()()1357946()()= on the calculator - i will get ERROR.
Contacted with the Huawei customer service for the help and got not nice answer:

We are unable to send boot loader code via email and can only be obtained through our website.
If you would want to unlock your phone, you should meet the following conditions:
1.Please register your Huawei ID in our official website on your phone.
2.Log in and logout your Huawei ID continuously for 14 days.
3.Each Huawei ID should not apply for the unlock code more than fifth time within 6 months.

Early people informed that email support works fast, but seems now the Huawei tightened terms.
Now i can expect 2 weeks everyday login to meet the requirements.
Some comments about tablet, maybe following helps someone.
One strange thing i've noticed with the tablet, it's not so easy bring up fastboot / recovery menu.
Pressing volume down + power brings up Chinese language test menu (8 options), nowhere to go with that,
pressing volume up + power brings up dialog with 3 options, "Reboot system now" or "Wipe data / factory reset" or "Wipe cache partition". Pressing by same all 3 buttons, volume up + volume down + power brings
up message that update not succeeded, update file not found on sd card. Also if you press only volume down and connect micro usb cable, it brings you to the Chinese test menu again. Also weird why European version tablet has at all Chinese test menu ?
I have triple boot desktop computer and i've downloaded 3 latest adb and fastboot platform-tools packages, for windows (using 10), mac and linux. With windows, using cmd i can start adb session, query device,
seems like everything works, when i'll try:
"adb reboot bootloader", device just reboots back to the main. Tried the same with the Ubuntu, same thing, adb helps finds the device, but when trying: "adb reboot bootloader" device just reboots into normal, not going into fastboot/rescue mode.
The thing is different with the mac (OSX 10.12), when i'll type to the terminal:
"adb reboot bootloader" the device rebooting into the fastboot mode.... and the terminal not responding any further, example when quering: "fastboot devices",
but having already fastboot mode activated on tablet and when rebooting desktop into windows 10 or ubuntu, i'm able using fastboot, tablet responds to the: "fastboot devices" or "fastboot oem get-bootinfo", even "fastboot oem unlock" responds informing about not valid key...
So far i'm able to put tablet into fastboot mode only using mac. Hope that's useful info for someone struggling
with same problems.
Unfortunately bootloader is still locked, problem finding product id, Huawei also did not help.
Huawei product id generator did not recognise Mediapad T3 versions.
Any ideas how to find product id or maybe someone can share the unlock code ?
Thanks in advance.

Hi guys,
I managed to unlock bootloader for BG2-W09, huawei sent to me. First time i tried (3 days ago) there was no way so i wrote them an e-mail. They replied i had to login 14 days wit my huawei id etc... but i tried yesterday and the sent the code inmediatelly.

Regarding getting ID with calculator it worked fine...first it appeared an ERROR mssg, but few seconds later the ID number apppeared, so my l3 7 has bootloader unlocked now, but I still need root... magisk way stock boot.img is required but i wasn´t able to obtain it..maybe someone here can help.

Hope this could help, thnx

the magisk app now can patch your boot.img so you can flash it through fastboot.

I really like this little tablet, got it at Walmart for 79 bucks. I tried unlocking the bootloader but was unsuccessful. Got errors. I emailed them and they told me that they could not help me with unlocking it :(

Think the issue is specifically with the MediaPad T3. I've just entered all details correctly into Huawei's unlock screen (including calculator code) and I get "Please make sure the information you entered is correct." :(

Hi, I have the same BG2-W09 wifi only tablet. I'm still unable to unlock the bootloader, in fact support answered that bootloader can't be unlocked for this device (I know it's bull****).
With calculator got the code, registered to site, filled the form with the correct data, but it didn't work for me.

Did you use chinese site? There is a post saying english version isn't working.

Thanks

Matias

    Hello folks,

    Bought a Mediapad T3 7 from Walmart recently. Has anyone found root yet? I tried all of the Kingroot, etc. APK's so far. Don't waste your time. Tried them all.

    If our magicians here can find root, I'd love it!

    Thanks,

    Rich

    Got the same request. Tried KingRoot and iRoot, cause you never know ;)
    I'd imagine it's coming one day or another. Tablet isn't that old yet.

    Recovery that works

    Here is a TWRP that I pieced together using Hovatek's twrp auto porter, Hovatek philz touch auto porter and AIK by @osm0sis. I say pieced together rather than ported because to I used pieces of stock recovery, several outputs from different versions of Hovatek's porting tools and @Huckleberrypie initial release twrp.img. It shows one error 'E:Unable to load '/twres/languages/en-US.xml' but I can't see where it is causing any problems so I left that part alone. Gave up on USB-OTG, I couldn't get it working after about 20 tries at editing I said the hell with it. Other than that everything works and I included /CUST and /OEM_INFO partitions in backup options. If you want to try it but aren't sure just boot it first instead of flashing. You can do that by "fastboot boot xxx-twrp.img" (xxx being whatever you change the name to). https://drive.google.com/file/d/1YnIS_L8fjxRaK2bKY1wVr66wAlgDvLCV/view?usp=sharing

    here is a smaller one from AIK output. the first was on I had used dd to copy from device. https://drive.google.com/file/d/1JQiX5_Y35zUDi4DfZ-0ulZuSVpcMPify/view?usp=sharing

    Thanks for putting this up! I did figure out how to do this, finally. Now have a rooted baby tablet which for a 1gb ram unit, works great. Very much appreciated.

    Hope this works: https://drive.google.com/open?id=1WV013glx0GKRoGsIW7t5t43PVDNnnw2z

    For convenience, this is the boot image patched from Magisk. Just rename it boot.img . This is for the wifi only bgw09 version that I got at Walmart. Hope this helps someone!

    Oddly enough SigmaKey Huawei Edition still does not have a solution to unlock that bootloader. I own a SigmaKey and have gotten a pile of huawei unlock codes with it, but still no solution for that one.
