Mute camera sound and remove red LED

The easy and safe way:
To remove the shutter sound, download this file HERE , it consists of a sis application and an rmp file. Install the sis application after signing, if your phone is not hacked and then goto the profile for which you do not need sound and set 'warning tones' to off for that profile. It works for sure on the silent profile, others you have to try. To remove the red led, download ROMpatcher and Install it after signing. Then copy the rmp file that came in the download to the 'patches' folder in memory card. Open ROMpatcher and enable the red led patch to make it become green and take options and set it to auto as well.

The manual way:
THE PHONE MUST BE HACKED
1. Open X-plore/y-browser
2. Goto "Z:\Private\10202be9\101F8809.txt"
3. Copy the file to "C:\Private\10202be9\101F8809.txt"
4. Edit the file "101F8809.txt"
5. At the end of the file, u will find the line

0x7 int 1 0 cap_rd=alwayspass
cap_wr=alwaysfail

6. Then change it to

0x7 int 0 0 cap_rd=alwayspass
cap_wr=alwaysfail

7. Save the file and exit X-plore
