All In One Tweaks For Android Handset

Tweaks ini saya comot dari berbagai sumber, baik itu di xda, modaco, maupun saya extract dari berbagai custom rom yg pernah saya test maupun saya donlot dg maksud mencari tahu setingannya...

Tapi semua setingan dan value atau nilai dari tweaks saya costumized sendiri, dg sedikit analogi dan baca2 tentunya..

Mohon untuk review dan kritikan yg membangun, jika ada yg kurang atau memiliki setingan yg lebih yahuud, silahkan langsung koreksi setingan saya...

Berikut beberapa list tweaks..

Metode yg digunakan adalah sama dg inject script di folder init.d di /system/ect/init.d
File mentahan, silahkan di download disini...
http://www.esnips.com/doc/a625b2db-f9ac-4f48-b854-eda0cc443ab9/All-in-One-Android-tweaks

Untuk metode inject ke systemnya, cukup mudah hanya berbekar root, dan aplikasi root explorer..

Cara instal / inject script:
Bahan yg dibutuhkan;
 - ponsel Android yg udah rooted (wajib)
 - aplkasi root Explorer dah terinstal

download All-in-One-Android-tweaks di link di atas, extract
ada beberapa file, nah berikut pembagiannya..

melalui root explorer, masuk ke /system/etc
buat folder init.d, kemdian jangan lupa set permission 777
v   v   v
v   v   v
v   v   v

copas semua file yg hasil donlot tsb yg ada di folder init.d ke /system/ect/init.d
jangan lupa set permission semua file satu per satu, ke 777
v   v   v
v   v   v
v   v   v

Nah yg juga penting adalah, copas file install-recovery.sh  ke /system/etc,
dan juga set permission
v   v   v
v   .   v
v   .   v

untuk build.prop dan gpsconfig itu optional, silahkan pakai jika dirasa perlu
dan ingat itu bkan untuk replace yg asli, hanya edit dan tambahkan line di bawahnya
tambahkan jika belum ada, dan edit jika telah ada
