This thread is for the MediaPad M3 Lite 10 LTE - Tablet from Huawei.
In my case, I´m looking for a C-ROM and C-Recov (e.a. RR, Mokee, TWRP) for the
Huawei MediaPad M3 Lite 10 LTE (BAH-L09) with Android 7.0 and EMUI 5.1
Since it´s quite new on the market it´s atm hard to find anything bout a C-ROM or even a C-recovery.

Nobody knows any thread about this tablet??

Still searching for a root-solution.
So it's possible to read out the firmware with Infinity Box CM2 but haven't found a working "Non-dongle"-version (Loader).
Some days, there will be a root solution.
It just takes time and will be posted in here.

I much appreciate the offer but what could u do if u haven´t the device or do u own it ?
Since my CM2-Infinity-box doesn´t work (usually I work with Miracle Box but it´s not compatible ...well the Tablet has to be rooted to read the firmware..), and literally tried all rooting-apps and progs, this device is really stubborn!

I own this device, thats what i told you

Very well. ?
Actually, just the stock-recovery is needed to finally start to compile it. Have u been able to extract the recovery or maybe the whole ROM ? ?

Well, to bad but I guessed so, since this device is atm not rootable. :/
I tried every single Flash-Box like MB, Infinity, Aladdin, Falcon etc pp.. any Rooting-App (APK & PC- based), almost a dozen flash-tools like ADT, AOS-flasher, Ultimate Backup-tool etc...and several command prompts via ADB&Fastboot.
Really Nothing helped to get a nandroid- or even a dumb ROM. From which I could extract the stock recovery.
Nevermind, I will try alil more with Holo- & Heliumbackup, which surely wont work but who knows, rite ??
I'm patient and as soon as I've found a solution I'll share it here immediately.
As any other user is welcome to do so, too.

I´ve managed to extract the stock-recovery via an OTA-update which came from Firmware Finder from Team MT.
U ´ll find the recovery on G-Drive. The "oldRECOVERY.img" is the extracted stock-recovery from the original BAH-L09C100B018 firmware!
So, since I´ve updated the Tablet, the only "RECOVERY.img"-named file is from the newest firmware which is L09C100B021!
If u wanna update to ...021, via the Firmware Finder-App, u need

Be aside your tablet

I bought the BAH-W09 model last week, anyone here unlocked bootloader on the lite 10 yet?

Yup, unlocked the BL from day 1. It´s the same procedure for all HUAWEI devices.
Just go here, login or register, confirm the unlocking agreement and put all device infos into the blank fields.
U´ll immediatley get an unlock code, which u have to enter via fastboot command prompts (recommended):
fastboot devices
fastboot oem unlock-go 1234567890123456 <- (this number is an example, u´ll have to put ur code there instead)
fastboot reboot
From now on an unlocked bootloader message will appear every time u start ur device. Just press power shortly to boot then. (It´s also written in the text aswell)
P.S.
Before u try to unlock: Don´t forget to enable USB-debugging in the Engineertool (tap 7 times on "build" in the settings-menue) and "allow OEM unlocking".

Ok cheers, I looked on the emui site and was nothing under their tablet menu only phones on the unlock bootloader page, on Nexus you just enable usb-debugging and click the OEM unlock in settings and fastboot flashing unlock in terminal. Sony uses a custom tool and HTC via their website I had a few phones in the past and built roms etc this my first Huawei device apart from my Nexus 6p Huawei help build with Google. I take it this device no official forum atm only the Kirin version.

Ya, HUAWEI has a quite faire unlock policy.
Important: There's an unlock bug sometimes. Be sure to have the Original firmware on ur device. (No updated ROM)
Have fun.

It's on latest official that came with device, I take it there is no twrp or anything out for this device ATM?

Just check a view posts above. I've described how to get the newest FW.
So if the factory ROM-version is installed, unlock the BL and after then update ur ROM. Jfi.
BTW_
Atm there's no custom recovery available for the M3 Lite Versions. U have to compile it by urself or make a request on Hovatek.com

I'm not bothered about updating the firmware ATM more so custom recovery but will look into it after my holiday.

I have requested official forum for this device and looks to be accepted so hopefully get some development going for this device soon...

There seems to be no way to retrieve the unlock code for Wifi-only tablets from the official Huawei site, as it demands the IMEI which is obviously missing.
I have contacted Huawei support with the product ID and serial number of my M3 Lite 10. One day later I have received the unlock code. I think that having been polite has helped

Storage question
Hello,
First of all: sorry, if the question is 'noobish', but as a matter of fact I am noob as far as android is concerned
I just bought this tablet for my son (LTE version), and I was quite surprised to find out that I can't move the installed applications to SD card.
Are there any hints and tips on how to take advantage of the big SD card, so my son's game data would not have to be stored in the internal memory?
The only default option is to change the memory from internal to SD, after the tablet restarts. But I assume it uses then only the SD card, and I am looking for a solution I remember from Samsung phone, where I could choose certain apps to move from internal memory to SD.
Another question, just by the way, is following: when I install an apk file from the SD card, during the installation process every few seconds I get a pop-up saying the application is not responding (although the installation is in progress). Any way to disable those annoying pop-ups?
I'd appreciate any feedback

Guide to update from EMUI 8.x(Oreo) to EMUI 9.x(Pie)

Hi In this Guide I am going to show a way to update Emui 8.x to Emui 9.x using Firmware Finder
It can be used on locked and unlocked Bootloader.
Data mostly wont be erased but will be erased in some cases where stock system is tampered earlier.
It may or may not lock your Bootloader.
For this you need to install Firmware Finder app ( https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder ) on your device , original thread for the app ( https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/ )
Note 1:
This method requires latest EMUI 8.X available for your device. If you are not on the latest update repeat the below steps to install latest EMUI 8.x for your device.
Note 2: This process is safe to proceed if you have selected correct firmware for your device , If you try to flash wrong firmware and bricked your device I wont be responsible for it.
Steps to Update :
1. Install Firmware Finder App ( https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder)
2. Select your Device in the App
3. Check the list of available firmwares
4. If you are not on the latest EMUI 8.x firmware then you need to install it
5. Select the next update iteration for your device
6. Check whether the update is approved your IMEI or not if check step 11 below
7. If the update is approved Get an update through eRecovery (Note that for this method you have to change DNS in your Router)
8. Click On Next and copy DNS address from the App
9. Change DNS in the Router and reboot your Router (Check whether DNS is configured properly or not by clicking this URL http://query.hicloud.com/checkConnect.action if you get 404 then its not configured properly)
10. Now click on the check availablitiy if not yet approved check next step
11. There is a option for Register update in the screen now click on register update and click next here your IP will be registered for sending the update
12. Now connect your device to charger and reboot into eRecovery by pressing Volume+ button
13. Once its rebooted cleck on the option Download latest version and recovery
14. On Next step Download and recovery
15. It will search for WiFi and will list the available WiFi , select the WiFi which you used to register your IP in step 11
16. It will proceed to download the select firmware once it done it will Reboot.

May be network issue or recovery package is not available for your device try it again after some time.
After changing DNS where you able to access the URL provided in the app ?

Sent from my HUAWEI COR-L29 using XDA Labs

Ive been trying this way on mine for weeks. I have the COR-L29 C432eu. It does find the firmware but it's the latest 8.x.x.132.

Only EMUI 8.1.X is approved.. EMUI 9.x isnt..
can I still force it to install? will there be any issues?

Easy tricks
The easiest way for honor play is to download a fake gps then change ur location to China and open HiCare -> update and you’ll see update available for you

HuRupdater is not yet available for emui 9 so I think it won't work.
You can use nocheck recovery to flash emui 9

Many thanks on help.

Dude seriously you are out of your mind just stay away from this thread if its not helpful to you , I have atleast two success reports for COR-L29 and the comment you quoted says EMUi9.x is not yet approved for his/her device which is quite common and the workaround for it is step 10 and 11.
I repeat again if its not working for you , you have mentioned it just thats enough and there is no need for spamming every thread.
If you wish to contribute and not spam just send a bug report to firmware finder team they might solve the issue.

Rebrand AL00 to L-29 script found, link in post!

Hi!
So i found a rebrand script for AL00 to L-29 on 4pda.ru through the https://forum.xda-developers.com/ma...-mate-20-x-global00ized-2-0-emui-9-1-t3920956 thread, by joining thier telegram group. For it to work an unlocked bl is required ofc, wich i have.
I haven't tested it, maybe someone with more knowledge could take a look at it? Here's the link http://4pda.ru/forum/index.php?showtopic=932930&st=920#entry89756746

That sounds great just what I have been waiting for.
Can you please share instructions?
Edit sorry just send the links they had not displayed before
Another edit... The script you link too no longer exists..

After rebrand from AL00 to L29, can I rebrand from L29 back to AL00? Unlock bootloader code still working? Thanks

Somebody tried?
Is it possible to change launcher then?
What about further updated, who knows.

Ok, let ask this and hopefully those who tried it already can provide an answer.
*The script is for changing your OEM info correct? Rebranding means being able to use L29 firmware as well. Can you explain how or what method did you use to flash L29 firmware?
*The instructions does not say it but do we need an L29 update.zip firmware ready?
*After FULLY rebranding your AL00 TO L29, can you now use 3rd party Launcher?

On telegram group, guy who done this few times said that you can change launcher and that it works only on 123, not 135...

Hi people!
Think i'm gonna try this today, but if someone has tested this. When rebranded have you also tested the option to Flash the L-29/global firmware and does it work? Is there a specific firmware you must flash first, or can i Flash the latest L-29 firmware directly?

Hi!
Iv'e been at this script several Times today.
Nothing works all the options does same thing, flashes recovery_ramdisk reboots, then tells me to hold power button+volume up. All that does is takeing me to eRecovery, then if I reboot the phone to fastboot, it says Flash firmware+cust in upgrade mode. Hit any key, i do that and the Windows closes nothing more. So how did you manage to rebrand? And when rebranded do you use L-29 firmware and get the system updates for the global version?

Hi!
I checked and nothing seems to change, ofc i cant check directly efter the script has run, becuase then it wants me to boot into erecovery. But if i turn it off, and start it in fastboot, it says same info again.
In erecovery it says downloaded latest recovery+firmware, but i'm afriad it will download latest AL00 firmware instead. Then i Will not be able to install transformation rom becuase of erofs is present in newer fw.

In theory, if you successfully changed OEMINFO AL00 to L29, then through erecovery downloaded latest recovery+firmware will restore the default FW of L29 (The oeminfo of L29 has been flashed to your device).

Hi.. has anyone managed this successfully? I desperately want to do this though am worried to brick my only device (That I currently can't afford to replace)
My device is currently AL00 9.1.0.135 is this the correct version for this script?
Could anyone do a detailed guide. For us worried people... Happy to contribute beer money, after successful rebrand if required.
Also I noticed looking at the script it installs Magisk to do whatever it does.... Will this trigger anything (like Samsung has Knox) as I don't want to be stuck with not being able to use gpay and banking etc.....?
Would I be able to remove Magisk after and go back to "stock"?
Sorry for all the questions just trying to work it all out before I take the plunge.

I am about to downgrade my P40 Pro and I have some questions

Hello,
Lurker here. I want to downgrade my Huawei P40 Pro to a lower firmware to install GMS. For what is worth, I did some digging around to find out what would be the most safe way to do it and this is what I came up (did).
Firmware: I saw a lot of people have problems with their phones rebooting because of a wrong firmware version. I wanted to download my own off of MT-Team's database, but I noticed, that I cant seem to find my exact firmware. To be more precise, I'm not just looking at my area code, but also at the exact same build number: C432E8R5P2. I can't seem to find this exact build on MT-Team's database, so went somewhere else. I already bought a firmware from this site (I cant post links so I will just add a photo).

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The firmware build number is exactly the same as mine (C432E8R5P2), not the mention that all the other info of the model and everything seems to check out. With what I bought, I would be downgrading to EMUI version 10.1.0.114.
Questions:
1. When choosing the right firmware, is its important that the whole build number matches? If so, have I chosen the right firmware? Do any of you know the vendor, is the software safe?
2. If the downgrade is successful, is its still possible to install GMS with an EMUI version 10.1.0.114?
Downgrade process: I am planning to wipe my phone clean before the whole process, buy an OTG cable and downgrade from an USB drive, because the whole process through HiSuite seems to have more risk, depending on the programs version, or am I wrong?
Questions:
3. Is it safer to downgrade from an USB drive via OTG cable, in comparison to HiSuite?
4. If the downgrade is not successful with the OTG cable/USB drive, what version of HiSuite should I use to downgrade the phone?
5. If my phone soft-bricks, are the any methods to fix it?
Thanks in advance

I successfully downgraded my Huawei P40 Pro.
Some details:
I could not go through with my initial plan, as the phone did not recognize the firmware, so I had to find another way.
I found my firmware (C432E8R5P2) via MT Firmware finder (PC), to version 10.1.0.131 with my exact firmware version (C432E8R5P2). Its number 409481 in the firmware finder, if this helps anyone. IMEI number also checked it out available for install.
I used HiSuite proxy and HiSuite 10.0.0.510 (because the newer versions did not let me connect to the proxy).
Wiped the whole phone clean + cache wipe.
Downgraded successfully and at the very end of it (once the downgrade is complete, it says it will now restart), restarted the phone to enter recovery (before it could restart into OS) - wipe the phone clean again + cache wipe.
Once booted, I did not get ANY errors, it was like a new phone. Used Googlefier to install GMS, it works.
Had NO problems with the phone, it let me update back to 10.1.0.176 (C432E8R5P2) and GMS is still working perfectly. No issues with the update, no use of HiSuite to update or anything.
10/10.
Hope this helps someone who has the exact firmware version as mine. I did not risk anything but the EXACT number as a whole. Worked the whole day to get this done.
Cheers

Hi I would like to know how to know its version on MT Firmware finder (PC) because there is a lot of version for my case I am looking for the 10.1.0.131 (C432E8R6P1) currently I am on 10.1.0.176 (C432E8R6P1) how to know the correct version to download and how to downgrade thank you

Hello,
Lurker here. I want to downgrade my Huawei P40 Pro to a lower firmware to install GMS. For what is worth, I did some digging around to find out what would be the most safe way to do it and this is what I came up (did).
Firmware: I saw a lot of people have problems with their phones rebooting because of a wrong firmware version. I wanted to download my own off of MT-Team's database, but I noticed, that I cant seem to find my exact firmware. To be more precise, I'm not just looking at my area code, but also at the exact same build number: C432E8R5P2. I can't seem to find this exact build on MT-Team's database, so went somewhere else. I already bought a firmware from this site (I cant post links so I will just add a photo).
The firmware build number is exactly the same as mine (C432E8R5P2), not the mention that all the other info of the model and everything seems to check out. With what I bought, I would be downgrading to EMUI version 10.1.0.114.
Questions:
1. When choosing the right firmware, is its important that the whole build number matches? If so, have I chosen the right firmware? Do any of you know the vendor, is the software safe?
2. If the downgrade is successful, is its still possible to install GMS with an EMUI version 10.1.0.114?
Downgrade process: I am planning to wipe my phone clean before the whole process, buy an OTG cable and downgrade from an USB drive, because the whole process through HiSuite seems to have more risk, depending on the programs version, or am I wrong?
Questions:
3. Is it safer to downgrade from an USB drive via OTG cable, in comparison to HiSuite?
4. If the downgrade is not successful with the OTG cable/USB drive, what version of HiSuite should I use to downgrade the phone?
5. If my phone soft-bricks, are the any methods to fix it?
Thanks in advance

That older method doesnt work anymore. See my thread ( in my signature, from computer) for the new methods.

You can't downgrade once you've upgraded

wouldnt there be a way through twrp or brom mode?

Nope you can try brom mode but i dont trust if works
If you buy a samsung device depending of the device (like this A12 and the MTK imei bug) is not a good idea to upgrade

That's samsung for you, once you've upgraded Binary version there's no going back.
As for the brom mode, samsung has locked their phones out of that mode. I don't know if accessing it through access points works but you could try to see if it can help

I tryed to downgrade via TWRP flashing baseband and BL
Now my A12 is DEAD and i dont had a box to repair it (after flash i see the security error screen and flashed again the Binary 3 BL once odin tell me passed the phone doesn't booted again)
I just wanted to get the imei working because the firmware on the binary 3 (11 and 12) android system uses all my ram memory trying to get the signal working
F*** *** Samsung and mediatek next time i bought an exynos or qualcomm variant

The last rom that i used on my A12 was pixel experience and worked perfectly on binary 3 android 11 based firmare (A125MUBUS3BVF1) just installed TWRP with nulled vbmeta flashed the image as system (not as super) and wiped the data (not advanced wipe) rebooted and the gsi was booted (only bugs mentionated on the thread and the touch bug)

How'd you do it?
Technically since I've always known that I can't access brom on my samsung I've never tried to understand what you can do with it.

I was only planning yo use the brom mode to use the MTK META Utility which is developed by Mediatek themselves for fixing imei to see if I can fix the imei issue with it but I couldn't enter brom mode and I'm afraid of opening the back cover

its relatively easy tbh. just be careful around the volume buttons, but everything else is okay. there arent too many cables to rip

Its easy to open but be careful with the power/fingerprint sensor flex i think the testpoint is near of the charger flex in the mainboard (i see youtube tutorials to access to Brom mode and preloader)

Hello,
If you're going to be performing a downgrade, you'll have to have the SCATTAR firmware with all of the old loaded certificates and tokens. Flash is going to be performed via BROOM (fused ROM code) useing SP_FLASH_TOOL.
Regarding the IMEI issue, that I'm not able to help with. And it is pain to work with, maybe you the MODEM file could help bout dbout it. You might have to go diging through firmware sites.
Thats it.
Stay safe,
Krypton.

SM-A125U Multitool Kit (Root/TWRP/Unlock/Unbrick)
Here is a toolkit of several tools ive collected and put together for the A12 in a single pack to help see through all the clutter and chaos of this forum, i have an A125U (converterd to a-125w) so thats all i can confirm working 100% but im 99%...
forum.xda-developers.com
Maybe this can help you only you need to download a firmware (don't try to flash a binary 2 or binary 1 firmware if you do that you phone will get a hardbrick and the sp flashtool will give the 0xC0020029 or the anti roolback error)
Pd: dont forget to change the date to 25/05/2022 to get the mtkmetatool working

You generate it your self

To unlock bootloader on these the easiest way is to convert it to an a125w xac by flashing the a125w bl files. Unlock bootloader with seccfg. Then flash ap, cp, and csc from a125w with odin and when it boots up it should show as a125w. Also in download mode it shows the same. My imei says unknown but i believe thats caused by unlocking bootloader so if you relock it after converting it should go back to normal. Playing with mtk modem tool to rewrite imei. Tried using xposed imei changer but didnt seem effective.
