The zip is bigger than 2,5 GB because inside the zip there are also the next folders :

1) ota (902,3 MB)
2) fota (940,8 MB)

TWO SUGGESTIONS :

1) I suggest you to keep only "bin" (1,7 GB) and "db" (16,2 MB) folders.
Then, rar it and share it on Needrom
2) Try to look for the twrp recoveries of the next devices :

[Only registered and activated users can see links Click here to register]

Of course only the Lollipop OS. Then, try to port them.

Thank you for the suggestions but I have tried porting the recovery from countless similar devices. With exactly the same specs and lollipop 5.1 but no go! None of them has touch working.

Hello

I will donate for you, Kindly confirm that you can make a custom recovery for my phone MT6797 Innjoo Pro 2.

I tried your way but it seems not working in my phone it goes back to the factory recovery.

also I cannot use bootloader because my phone is locked, and I couldn't find any way to unlock it.

Thanks

Yes you are correct, I type it by mistake it is MT6757

Also please be aware that when I try to flash the custom recovery from ADB, its give me a message that my device is locked. as below:

C:\Users\Majed>fastboot flash recovery recovery.img
target reported max download size of 134217728 bytes
sending 'recovery' (14054 KB)...
OKAY [ 0.467s]
writing 'recovery'...
FAILED (remote: not allowed in locked state)
finished. total time: 0.475s

C:\Users\Majed>


When I try to unlock it I cannot press volume up " no response to confirm the unlocking.

Also, when I try to flash the custom recovery from "SP flash tool" it works, but I cannot boot to the custom recovery its like the OS refusing the flashed image and replace it with the factory one.

I appreciate you help me on this.

@majed2010sa :

Please try once again to unlock the bootloader.

STEPS :

1) Connect the phone to the pc via USB cable.
2) Open CMD (command prompt).
3) Type the next command :

adb reboot bootloader (and press enter)

4) Now type the next command :

fastboot oem unlock (and press enter)

5) Press volume up (into your phone) to confirm to unlock the bootloader.
You will see in the CMD prompt the next messages :

"Start unlock flow", and when it will be finished, you will see "OKAY".

6) Reboot in normal mode (be patient, when you unlock the bootloader, the phone reset to factory).
7) Now tap seven times on Build number.
Then Developer options, and re-enable OEM unlocking and USB debugging.

Please keep me update about the situation.

Please keep me update about the situation.

Still its been 15 minutes and no response , not even something shows that there is process in the background.

I have pressed yes up volume but nothing changes the phone screen still in the confirmation stage, but when I press down volume its response and send me back the main menu.

C:\Users\Majed>adb reboot bootloader

C:\Users\Majed>fastboot oem unlock
...

When I went to Developer options, and re-enable OEM unlocking and USB debugging. its asking to put my pin key, is it something can cause the issue to not be able to unlock the phone through the bootloader?

Boys ... please be patient ... please consider the Italy time zone
