Install Apk is Blocked

[expenaticx]

Hello ,,
I have this payment machine that is based on MT6572 CPU.




The Firmware installed in that machine is customized not to install any apk.
If i try to install any APK , it will give this Message



Developer option in android Setting can not be enabled.
There is no option to enable Unkown Sources in android Setting.
So , is there any way to install APK on this machine ?
Ps , i had read the firmware from that machine as a scatter file.

Mobogenie need USB Debug Enabled which is not possible.

And if you tap on the build number 7 times, you don't see Developer options enabled?
If tapping on build number 7 times don't enable developer options, you can try others like kernel version or stuff like that

That is correct , no Developer option enabled.
Is there any way to write APK to System/App (like write nv_Data).

Use Maui META 3G ver 6.1316.1 to boot phone into meta mode and use adb command or Android Multi Tools to check if adb is offline or online after meta mode.
If adb is online, you can use command to try and install apk and see result.

But you still need to explore the phone very well to locate where the developer enabler option is hidden.
Sometimes it is in strange location

I successfully gain access to ADB via this factory recovery mode.
ADB commands is working.



Put system and data partition is read only and can not be mounted to copy apk inside /system/app (permission is not permitted).

Via this recovery mode i can also boot into fastboot mode.
Is there any way to add apk inside system.bin that i already red from the phone , and then flash system.bin to the phone again !

Get root and remount system as RW?

If you get adb command working, then you can install apk file without problem
Get this
1. Put on desktop and extract it
2. Put the apk file in the folder
3. Press 'Shift' and right click after opening the folder
4. run adb command to install apk.
eg. you want to install whatsapp.apk
put the whatsapp.apk file in the folder and run this command 'adb install whatsapp.apk'
If you want to reinstall or update the app
run this command 'adb install -r whatsapp.apk'

There in no root or custom recovery available for this brand.
MobiPrint 3

You must wait and see the word 'succes' on the interface before disconnecting phone
Did you put the apk files in the folder before running the command?
You can as well connect phone to mobogenie in the factory mode to install the app

As you can see from img i waited and did not disconnect the cable , but no 'succes' appears.

Well bro, if not success, then I guess you need to work on this first but I wonder if you can gain root access with your system 'read only'
For root, you can download desktop version of kingroot or kingo root or others and give a try

Dear all masters,

Open adb kit (Command Prompt).
type adb shell
type su
You should see a # in your prompt.
type mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system.


check whether it works or not.

p.s: i am a novice and this commands was searched from xda indeed.
