adb usb debug မ on ထားတဲ့ ဖုန္းမ်ားကို usb debug on ျဖစ္ေအာင္ recovery မွတဆင့္နွင့္ boot.img ျပ ု ျပင္ ၿခင္း ျဖင့္ ရေအာင္ လုပ္ နညး္ (general knowledge)

reboot into recovery mode 

recovery က ေန data partition ကို mount ဖို ့ 

/data/property/persist.service.adb.enable

mount ျပီး အဲ့အပိုင္း ကို ျပပါ 

echo 1 > /data/property/persist.service.adb.enable

1 ဟု ေျပာင္း

boot.img မွာ usb debug enable ျဖစ္ဖို ့ ျပင္ရမည့္ေနရာ default.prop and system/build.prop

Added to default.prop and /system/build.prop

Code:

persist.service.adb.enable=1 

persist.service.debuggable=1

persist.sys.usb.config=mtp,adb

recovery က ေန mount ျပီး ျပင္ဖို့

adb shell

su

mount -o remount,rw /system

cd /

echo “persist.service.adb.enable=1” >> default.prop 

echo “persist.service.debuggable=1” >> default.prop

echo “persist.sys.usb.config=mtp,adb” >> default.prop

echo “persist.service.adb.enable=1” >> /system/build.prop 

echo “persist.service.debuggable=1” >> /system/build.prop

echo “persist.sys.usb.config=mtp,adb” >> /system/build.prop

ဒီေနရာမွာ echo က default.pro and build.prop ထဲကို value ေတြ ေပါင္းထည့္တာပါ

stock recovery ကို သြား

For Jellybean 4.2.1:

Boot into Recovery and mount Data partition.

Open a shell on PC and type:

adb pull /data/property/persist.sys.usb.config ~/

Repace ~/ with home directory of your OS.

Open that file in a text editor and you would possibly see mtp written there. Change it to mtp,adb.

Note that sometimes Android doesn’t understand the text file changes if the line terminator is “DOS Terminators” which Notepad would probably do on

Windows (mine is Linux so no issue here).

In that case, I would suggest not using adb pull but doing:

adb shell

echo ‘mtp,adb’ > /data/property/persist.sys.usb.config

You may verify that the echo command overwrote the file by using:

adb pull /data/property/persist.sys.usb.config ~/

and seeing the file’s content in some text editor.

Unmount Data and reboot into Android OS. USB Debugging would probably be enabled.

For Lollipop 5.0: 5.0 မွာ က်ေတာ့ DB Browser နဲ့ /data/data/com.android.providers.settings/databases/settings.db ကို ျပင္မွ ရပါတယ္

the global table မွာ value ေတြကို ေျပာင္းေပးမွ ရပါမယ္

JB 4.2.1 users can also follow this method if the previous one didn’t work for them.

Boot into Recovery and mount Data partition.

Repeat step 2 and 3 used in JB 4.2.1 method.

We need to tweak some parameters in settings.db. Type:

adb pull /data/data/com.android.providers.settings/databases/settings.db ~/

Back it up at some other location too, and open the file in an SQLITE editor. I’m running Linux and DB Browser for SQLite works well. It’s also available 

for Windows OS/OSX.

http://sqlitebrowser.org/

In the global table, change the value for:

adb_enabled to 1

development_settings_enabled to 1

Check that verifier_verify_adb_installs is set to 1 in the global table.

Check that as default, in the secure table:

adb_notify is 1

adb_port is -1

These checks in step 6 and 7 are not necessary but should be done so that troubleshooting becomes rather easy if the solution doesn’t work for you.

Save the changes in settings.db and copy it back into Android by typing:

ေျပာင္း ျပီး ျပန္ ထည့္ေသာအခါ ရိုက္ရမည္ command

adb shell 

rm /data/data/com.android.providers.settings/databases/settings.db

exit

adb push ~/settings.db /data/data/com.android.providers.settings/databases/

That delete (rm) command is not necessary since adb push should overwrite the file, but I executed it for my peace of mind.

Unmount Data and reboot into Android OS. ADB probably would be enabled.

rm ဆိုတဲ့ command ကို အထူးတလည္ရိုက္စရာမလိုပါ push သံုးလုိက္တာဟာ အစားထိုးသြားပါလိမ့္မယ္

ဒါကေတာ့ sqlite3 ကို သံုး ျပီး 5.0 ေတြမွာ usb debug enable လုပ္ဖို ့ ျပ ုျပင္သြားတဲ့ command ပါ 

Code:

adb shell

su

sqlite3 data/data/com.android.providers.settings/databases/settings.db

update global set value=1 where name=’adb_enabled’;

exit

exit
