If you try to read carefully the whole OP, you'll find for sure what TWRP you need ... Also into OP and the second post there's all steps that you need in order to install correctly TWRP an LOS. Good luck 🤞
Hi Petru, could you please re-upload the latest firmware LineageOS-15.1-BTV_2021-05-13.zip ?

The original link is down.

And seems like one 2021-03-07 above was not the latest release.

Thank you!

Hello, please tell me if Huawei m3 supports video playback at the hardware level as 1440p60 in the Lineage OS firmware?

I understand that this question may seem strange, but I can't find the exact information on this issue. Someone says that this support is available on this processor, and someone on the contrary claims that there is no support.

Personally, I have the factory firmware BTV-DL09C170B352, suits me almost completely, except for the support of video 1440p60, the video on it slows down. I think to flash to Lineage OS if there is support.


So before the firmware, I would like to ask you if the video is playing on your device with the new firmware. I use the tablet mainly to watch videos via Youtube, and I am very interested to know if flashing will help me or not?

    The new kernel 4.4.0 it's coming soon !

    Hi !

    I was able to successfully update the kernel from stock 4.1.18 to 4.4.0 without to break anything !

    Currently the kernel is on 4.3.0 but there are very few patches ( I think around 1000 new patches need to be added to the over 14,000 already added ) left to add up to 4.4.0, so I allowed myself to do a simulation for 4.4.0 to see if our device really boots with this new version !

    I hope that in a week we will have here the new update with the new security patch for August and with the new kernel 4.4.0.

    Later the kernel must be updated to 4.4.227, which is the latest version today :)

    TWRP 3.3.1-0

    TWRP 3.3.1-0


    You need this new TWRP in order to flash Lineage OS 15.1 !

    Must be installed only on Android N EMUI 5.x

    Working on all Huawei MediaPad M3 8.4 with Android N EMUI 5.x !



    Download :

    twrp-3.3.1-0.img md5: 984779bc7af812eb1b3e67e197732dbc

    Installation :

    adb reboot bootloader

    fastboot flash recovery twrp-3.3.1-0.img

    fastboot reboot


    You need to FORMAT Data in order to decrypt /data, you need this step because LineageOS 15.1 do not have implemented right now encryption/decryption support !
