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.

T3 7 bootloader unlocked

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
[General Questions and Answers] -Hope-:
the magisk app now can patch your boot.img so you can flash it through fastboot.
[General Questions and Answers] juesgu:
Yes I know but how can i get my boot.img? Will magisk app detect it? That´s the problem i´m having. Maybe the answer is obvious..but I´m a newcomer ...

As per my message, easiest way would be source your firmware (service one) and do it. Check here http://combinefile.com/home/browse/category/id/13/Huawei_Firmware

If not available, email them and they may upload it for you.

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 :(
[General Questions and Answers] pastorbob62:
How did you get the unlock code?

I have the same device and I cannot find any way on their site to get the code. :confused:
[General Questions and Answers] -Hope-:
You must contact them directly through email
[General Questions and Answers] GartimusPrime:
I didn't get it at all. I contacted them via email and they told me they don't help with bootloaders.

I was able to "uninstall MANY apps using the method at this xda website.

Are you sure?

Try to recontact them
[General Questions and Answers] GartimusPrime:
This was my response

Attached was a PDF saying they don't help with bootloaders
[General Questions and Answers] -Hope-:
But they say in the unlock page that if anything went wrong contact them

Did you use the link used in the bootloader page?
[General Questions and Answers] GartimusPrime:
That's the link I clicked

No i don't own the device but many used the link to unlock

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

I managed to unlock the bootloader, but have no success in rooting. Using magisk option to patch boot.img always ends up in a patched_boot

img that's file size is just 7, 45 KB. I don't know what I'm doing wrong, maybs someone can help.
[General Questions and Answers] tek3195:
Try going to Magisk archives and use 14.0 when the install toast pops up select release notes and you will be able to find it. flash the patched_boot.img from 14.0 then upgrade through Magisk manager to 16.4 Beta. 16.0stable doesn't work on mine. you have to select beta in settings then dowload zip only. When downloaded go to Modules (it will be empty) and hit the yellow plus sign and navigate to your Magisk Manager folder. Select the 16.4 .img file and watch it go. you have root access and the manager to control superuser permissions but modules fail. 95% of root apps I have tried work and you can also install Xposed from this point with Unity Xposed Installer flashed through Magisk Mgr. Been using it this way since 13.1, nowhere close to perfect but alot better than what we had to start with. Make sure to have UPDATE.APP in dload folder on sdcard. You need to get the one for BG2-W09C128B023(988MB top or bottom doesn't matter) from F.F. app and just use direct download(no proxy). Good Luck.

As much as I dislike saying this, use UC browser and go to >settings>browsing settings>website preferences(UA)>others and select desktop. That's what I remember from over a year ago but at that time it was the ONLY way it would work.
[General Questions and Answers] Kilian07:
Thank you for your reply.

Unfortunately, I'm not really able to get Magisk Manager 14.0. If I install the corresponding .apk (e.g. 5.3 or 5.6.3) the app only offers updating to the newest version instead of showing an option to install / patch the boot.img.

Please explain a way more detailed how to achieve v14.0.
[General Questions and Answers] tek3195:
You're in luck in a round about way. Turns out the Xposed is not a great idea just yet. I only got it on there 3 or 4 days ago and not sure how to describe it now other than so buggy that it's not worth the aggravation trying to figure it out. **** just don't work. So I will be starting it all over again today and will let you know once it's fresh in my head. It will be a little while as I'm in the middle of swapping OS's on my PC SO I'm without platform tools temporarily. But I'll help you get it.

Cool, turns out easier than ever. I wiped the tablet clean. Flashed SYSTEM, RECOVERY, and BOOT .img files then ran UPDATE.APP from sd card effectively locking boot loader and starting as factory fresh as I could. EASY!!! Wait for it... Beta. That's our new answer. Latest Magisk Manager, "no thanks" at the install toast. Go to settings and select Update Channel, hit Beta. Exit settings and hit install. Hit install again on pop-up for installing Magisk-v16.4(1642).zip. Select Patch Boot Image File. Navigate to your stock boot.img and watch the Manager work it's Magisk. We are still at a disadvantage not having custom recovery to be able to flash from and to specific partitions. But root apps work and Magisk Manager handles permissions so it's not all that bad. F.Y.I. Flashify and Rashr depend on custom recovery to flash anything. Flashfire Pro is awesome on my Galaxy Grand Prime but has left me with numerous softbricks on both of my T3 7's. Chainfire knew what he was talking about when he put the Huawei warning front and center. Last thing I can think of is if you experiment with Xposed don't let it reboot from module page, instead go back to framework page reboot to recovery. Then reboot system from stock recovery without wiping dalvik cache. Some modules won't activate if you wipe it. We need to lobby TopJonWu to build the Manager capable of flashing .zip and/or .img files that aren't of the Magisk Module flavor. We cannot be the only ones using Magisk for root access without recovery. But, with all the work that he does I don't see that happening. Have fun with it. Any problems, let me know, any better outcome, Please let me know.

I forgot to mention you were right about patched_boot.img. 16.0 produces an .img of 7.45KB 16.4 SHOULD give you one 10.89MiB
[General Questions and Answers] Kilian07:
Thank you for your detailed help!

Now I managed to root it by following your instructions. Finally I could debloat it and get rid of all that google junk.

For me as a newbie it was a quite challenging task, but it was worth it.
[General Questions and Answers] Haeken:
Hi.

I might be stupid but, i got the

Magisk 16.4 installed on my tablet, but i dont get it to make me an boot.img file?

Or how do i get the boot.img file?

Would be awesome if someone who knew could help

Thanks in advance.
[General Questions and Answers] dorpmuller:
Same here... call me dense, but where do I get the boot. img file?

Still not quite getting this... could someone do step by step instructions?

1) do this

2) do that

and so on.

Thanks,

[General Questions and Answers] dorpmuller:
But *where* do we get these files? Need much more detailed instructions and sources.
[General Questions and Answers] tek3195:
I will try to help as best as I can. Bear in mind that I am new to this myself(about a year and a half ago an apple was a piece of fruit and an android was something from a space movie). I'm an old dog trying to learn new tricks. Limited knowledge, less experience and no typing skills. I'll not write a guide as I'm not qualified to instruct anyone on anything of this nature. I will try to write out what I did and maybe you will learn my eperience.

First downloaded firmware finders app from play store. Searched for BG2-W09C128B023 and downloaded the one that was 988mb. I then used Mixplorer to open the update.zip and copied UPDATE.APP to dload folder

on external sd card. Then I downloaded UPDATE.APP Extractor by Worstenbrood from Xda. I copied same UPDATE.APP from dload folder to a folder on PC for extracting. I still dont have a full understanding of the whole .img file thing yet. But, I used the first BOOT.img I seen (which is stripped of its headers) as well as the recovery.img and system .img . I moved those to my adb folder. I used minimal adb and fastboot with system wide installation and mine is labled C:\adb. I actually placed those 3 files there for future use. Copied BOOT.img back to tablet and placed it where I would remember it which was in my Magisk Manager folder. When prompted for boot.img I navigated to MagiskManager folder and selected BOOT.img. After Magisk patched the BOOT.img I copied the patched_boot.img file to my adb folder on PC. I used fastboot to flash patched_boot.img and rebooted. Once tablet rebooted I opened Magisk and found that wonderful green checkmark saying installed. It took a lot of reading and a lot of trial and error on my part just to get to where I could figure this out. I've done A LOT since then so I tried to leave out confusing and unneeded info for first time Magisk installation. Hope this helps a little.

[General Questions and Answers] Okom1:
Huawei stopped giving out bootloader unlock codes on devices that were put out to market on 24th of May 2018 OR on 22th of July for devices put out to market before 24th of May 2018. So if you didn't get a bootloader unlock code before the date, then there is no way atleast that I know of to root your Huawei device. Sorry.

Does it mean that we can do anything without the bootloader?

If you are just now thinking about rooting your BG9-W02 then you're too late, because you can't get a unlocked bootloader anymore.

I suggest reading the thread before posting.

Weird multi-touch issue with Sixaxis Controller app

I am trying to control my tablet screen with a geniune PS3 controller with bluetooth using an app called "Sixaxis Controller". I have made a custom profile in the Sixaxis Controller app to match the on-screen controls of my quadcopter drone controlling app (Breeze Cam). I have two mobile devices (Huawei MediaPad T3 7, Samsung Galaxy J3 (2017)), which both are rooted. I have created two different profiles on the Sixaxis Controller app, one for each of my devices to match the drone app controls (because different resolution screens).

The profile works fine on my Galaxy J3, but on my Huawei MediaPad it pulls the first emulated button-press towards the next button-press if I'm trying to press two or more buttons at the same time. I have tested with a multi-touch test app that the tablet can understand a maximum of 5 multi-touches at the same time and work, but when I try to control the screen in that same multi-touch test app with my PS3 controller, it again drags the first button towards the set place of the second button.

Here is a video detailing my issue: https://youtu.be/Ea_5BRVkKpc

The description of the video has some info about the apps and devices.

Thank you for the help!

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 [MENTION=4544860]osm0sis[/MENTION]. 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 [MENTION=329517]Huckleberry[/MENTION]pie 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

Hello,

I try to install Magisk via boot image on my MediaPad T3 7 ( Model: BG2-U01 ) but something is wrong.

i would also try the twrp but cant find it for my model.

What i did:

- succesfuly unlocked the bootloader with help of that one special guy...

- installed the current Magisk Manager ( v7.1.1 )

- downloaded the update.zip for exactly my model, extracted the "BOOT.img" and put it on the phone storage

- patched the boot.img with Magisk ( v18.1 ) and transfered the "patched_boot.img" back to my PC

- boot the device into fastboot mode

when i try to flash the original BOOT.img everything is fine.

device works - and all ok

>fastboot flash boot BOOT.img
target didn't report max-download-size
sending 'boot' (21681 KB)...
OKAY [ 1.053s]
writing 'boot'...
OKAY [ 0.847s]
finished. total time: 1.905s

but here is the problem:

when i try to flash the "patched_boot.img" i get this error

always same error
[General Questions and Answers] tek3195:
Try booting your patched .img instead of flashing. Use fastboot boot patched_boot.img I don't know that will work but if it boots from it you'll know if it is the boot.img or tablet security causing the issue. That may give you a better idea of where to look. Also search Magisk threads to see if anyone else has reported same problem. If not, then post in there. Surely someone will know the answer. There are some peoplein there that are really good with all kinds of boot.img ****ery. Good luck.
