Hello !

There is a high risk of damaging your device following this tutorial. Try to read everything below and make sure you understand before taking action. No one else is responsible for what you do with your device !​

Lower will find the information needed to change the system partition from 2GB to 5GB - this operation is somewhat useful for installing any version of GApps on your device : Huawei MediaPad M3 8.4 Kirin version ( BTV-DL09; BTV-L0J; BTV-W09 )

Thanks to @accerian for his help, and you can also check out this tutorial for more information !

Download mkfs.ext4 and parted from here : https://xdaforums.com/attachments/parted_gdisk_fdisk_mkfs-ext4-arm-zip.4494671/

Warning : the entire data partition will be deleted following this procedure, make sure you have backed up and saved it to a microsd card

Step I : extended system partition from about 2GB to 5GB ( example for a 32GB device, for 64GB devices the procedure is 99% similar, only one operation differs which will be specified at the appropriate time ) - also this example is for BTV-DL09 which is with LTE capabilities.

- extract "mkfs.ext4" and "parted" from previously download archive and put them into a new created tmp directory

- connect the device to the computer via the USB cable and bring the device into TWRP revovery with this command :

> adb reboot recovery

- copy the two executable files from the computer to the device :

> adb push tmp data/local

> adb shell

# cp -r data/local/tmp/mkfs.ext4 sbin/mkfs.ext4

# chmod 0777 sbin/mkfs.ext4

# cp -r data/local/tmp/parted sbin/parted

# chmod 0777 sbin/parted

- launch the "parted" function as follows :

# parted /dev/block/mmcblk0

- display all properties of all partitions : (I wrote what needs to be displayed as a command before pressing enter, so you just have to type "print" and press enter because (parted) is already displayed as promter ... be careful not to type (parted) twice in the following commands)

(parted) print

- go to line 43, which should be the same for all devices :

- if line 43 is not identical to this one here, please stop the process by writing quit and enter, I'm waiting for a private message with what is written on line 43 in the case of your device so that I can guide you correctly .

- assuming that all devices have the same system partition ( the same 43 line ) - approximately 2GB, we go to the next steps:

- access the Mount menu in TWRP and uncheck Data, and follow the steps below step by step :

( be very careful, if by mistake you wrote a wrong command in the prompter (parted), this cannot be corrected later, for example if instead of "rm 49" you wrote "rm 40" you can no longer delete 0 to add 9 in place, try to write the commands below as slowly as possible without absolutely the slightest mistake )

(parted) rm 49

(parted) rm 48

(parted) rm 47

(parted) rm 46

(parted) rm 45

(parted) rm 44

(parted) rm 43

(parted) mkpart system ext2 1174 6501

(parted) name 43 system

(parted) set 43 msftdata on

(parted) mkpart cust ext4 6501 6702

(parted) name 44 cust

(parted) set 44 msftdata on

(parted) mkpart version ext4 6702 6736

(parted) name 45 version

(parted) set 45 msftdata on

(parted) mkpart vendor ext2 6736 7374

(parted) name 46 vendor

(parted) set 46 msftdata on

(parted) mkpart product ext4 7374 7575

(parted) name 47 product

(parted) set 47 msftdata on

(parted) mkpart hisitest 7575 7579

(parted) name 48 hisitest2

(parted) set 48 msftdata on

- for devices with 32GB :

(parted) mkpart userdata 7579 31.3GB

- for devices with 64GB :

(parted) mkpart userdata 7579 62.5GB

(parted) name 49 userdata

(parted) set 49 msftdata on

(parted) quit

Step II : activating partitions for reuse :

# mkfs.ext4 /dev/block/mmcblk0p43

# mkfs.ext4 /dev/block/mmcblk0p44

# mkfs.ext4 /dev/block/mmcblk0p45

# mkfs.ext4 /dev/block/mmcblk0p46

# mkfs.ext4 /dev/block/mmcblk0p47

# mkfs.ext4 /dev/block/mmcblk0p49

- go to TWRP -> Wipe -> Advanced Wipe -> select System -> Repair or Change File System -> Change File System -> EXT4 -> Swipe to Change

- go to TWRP -> Wipe -> Advanced Wipe -> select Vendor -> Repair or Change File System -> Change File System -> EXT4 -> Swipe to Change

- go to TWRP -> Wipe -> Format Data -> yes

- reboot device from TWRP to TWRP in order to use data again after formated !

- go to TWRP -> Wipe -> Advanced Wipe -> select Dalvik/ART Cache, Cache, Data, Internal Storage, System, Vendor -> Swipe to wipe

- copy the new updated of LOS 17.1 with system partition of 5GB into your device

- copy any GApps arm64 Android 10 to your device

- Install them like always, enjoy !

Mention :

- if your device is WiFi only, you may have fewer partitions .... the above instructions can be easily adapted from case to case !

The main idea is that we must first find out what position the system partition is in, in this case it was at position 43 which corresponds to /dev/block/mmcblk0p43 - then we need to delete all partitions from userdata to system, and recreate them in the same order !

To calculate the start and end position, it is again very easy : for example the system partition starts from the initial position 1174, which is the same as the end position of the previous partition 42 (42 1160MB 1174MB 14.7MB reserved3 msftdata), and the end position was incremented by 5327 in this case (almost 5GB), resulting in 6501. .. the next partition 44 (cust) will have the starting position 6501, and the end position will be incremented by 201 (i.e. 201MB) as shown on line 44 (44 3255MB 3456MB 201MB ext4 cust msftdata)

Workaround

- if you still made a mistake in the prompter (parted), you can correct it later by following this example:

let's assume that instead of the command

"(parted) rm 49"

you wrote :

"(parted) rm 40"

by mistake... in this case, before pressing the ENTER key to go to the next command, add another digit like this so that partition does not exist, for example :

"(parted) rm 400"

- and press ENTER, in this case you will be asked once again which partition you want to delete, having the possibility to enter 49, the value you had to enter by at the beginning.

If really needed, a concrete example will be added here for WiFi only devices !
