if you ALREADY HAVE the camera.apk you want to install...then good. IF NOT, go download JF1.51 and pretty sure it will have the Google version camera.apk...MAKE A NANDROID BACKUP BEFORE YOU BEGIN!! I AM NOT RESPONSIBLE FOR ACCIDENTS! This is a simple procedure, so please pay attention and do this carefully, Its not my fault if your phone gets bricked. That being said, i have done this more than once and never bricked my phone. THAT being said, I CANNOT GUARANTEE YOU THE SAME RESULTS, SO PLEASE! PLEASE! BACKUP YOUR DEVICE AND YOUR DATA BEFORE ATTEMPTING THIS!
First go into terminal on your device and type:
mount -o rw,remount -t yaffs2, /dev/block/mtdblock3 /system
this removes the HTC versions from your phone. Then just go ahead and push the google version camera.apk. The adb commands are:
adb push /exact/path/to/your/camera.apk /system/app
remember, DO NOT type "/exact/path/to..." replace this line with the path on your computer where you have the camera.apk, for example,
/Desktop/Android/camera.apk is where mine would be...
then thats it. FYI, the HTC version has a separate gallery, the HTCAlbum.apk...THE GOOGLE VERSION DOES NOT HAVE A SEPARATE .APK FOR THE GALLERY. once you have pushed to google camera.apk you SHOULD have the camera and gallery and all...Good Luck!
