Bytecode · Jun 14, 2011

Hi there pals! It seems that the actual wish of n00bz is cooking their own rom. Well,i got some tips for you now.

*Kernel:
The Linux kernel is the center of the entire Android system. Today i'm gonna show how to put it in your rom:You'll need the kitchen. Multiupload.com - upload your files to multiple file hosting sites! Extract rom,then go to advanced options. Select option 20 and then option w. You'll find a new folder,BOOT-EXTRACTED. You'll find in this folder a file named zImage. Replace it with the fixed one that you can find in kernel folder of zip file,select option b and cook. THEN copy:
/zipfile/system/lib/modules/tun.ko to /WORKING/system/lib/modules
/zipfile/system/lib/modules/wireless.ko to /WORKING/system/lib/modules

*Frameworks
For customizing your UI and make it cool,you'll need the kitchen.Multiupload.com - upload your files to multiple file hosting sites!
Extract it and go to advanced options. Select option 11,wait and in WORKING open framework-res.apk w/ 7-zip and customize all you want. If you want to put another framework than the stock one,extract the original one and keep META-INF folder. Replace stock one with the custom one in framework folder,and open it with 7zip. Replace META-INF folder in apk with extracted one and cook.

*WiFix
How to apply WiFix?
Download this:http://www.multiupload.com/CVBPXA46DB. Extract downloaded file and extract rom with kitchen. In kitchen go to advanced options and select option 20,then option w. Open BOOT-EXTRACTED folder and in boot.img-ramdisk open init.thunderg.rc and put in this string:

Code:

on property:init.svc.wpa_supplicant=running
    exec /system/bin/sh /system/etc/setwifi.sh

then select option b.Copy setwifi.sh in /WORKING/system/etc and iwmulticall in /WORKING/system/xbin .Now,in /META-INF/com/google/android/ open updater-script and add these strings:

Code:

symlink("iwmulticall", "/system/xbin/iwconfig");
symlink("iwmulticall", "/system/xbin/iwgetid");
symlink("iwmulticall", "/system/xbin/iwlist");
symlink("iwmulticall", "/system/xbin/iwpriv");
symlink("iwmulticall", "/system/xbin/iwspy");
set_perm(0, 0, 0755, "/system/xbin/iwmulticall");
set_perm(0, 0, 0755, "/system/etc/setwifi.sh");

in WORKING folder go in system folder. Open build.prop and search for this string:

Code:

 wifi.supplicant_scan_interval=20(Replace 20 with 260)

*Enable hardware acceleration
in Working folder go in system folder and open build.prop. Search for this string:

Code:

debug.sf.hw=0(Replace 0 with 1)

Cook it.

*Heap size
In working folder go in system folder and open build.prop. Search for this string:

Code:

dalvik.vm.heapsize=24m(replace 24 with 32 or 40)

Cook.

*ZRam module
Download zram.zip from here and extract it. Copy:
/zram.zip/system/bin/zramconfig to /WORKING/system/bin
/zram.zip/system/etc/zram.sh to /WORKING/system/etc
/zram.zip/system/etc/init.d/00remount to /WORKING/system/etc/init.d
/zram.zip/system/etc/init.d/00zram to /WORKING/system/etc/init.d

*Stagefright player
Open /WORKING/system/build.prop with a text editor(Notepad++) and search for

Code:

media.stagefright.enable-player=false

and replace false with true to enable it,replace true with false to disable it.

More tips are on the way!

Is there a list of apps which are safe to remove?

Bytecode · Apr 27, 2011 at 1:40 PM

Well,no. You'll need to be careful removing apps in app folder.

Well first you need to adapt kernel.

Xumit · Apr 28, 2011 at 6:09 PM

Just a small revision the the META-INF\com\google\android\update-script syntex. I kept getting errors in my update-script check, and found Ciaox had posted the version below in another forum (that was not english, but I recognized the code!).

Code:

symlink iwmulticall SYSTEM:xbin/iwconfig
symlink iwmulticall SYSTEM:xbin/iwgetid
symlink iwmulticall SYSTEM:xbin/iwlist
symlink iwmulticall SYSTEM:xbin/iwpriv
symlink iwmulticall SYSTEM:xbin/iwspy
set_perm 0 0 0755 SYSTEM:xbin/iwmulticall
set_perm 0 0 0755 SYSTEM:etc/setwifi.sh

I also found the supplicant scan interval bit in the boot.img-ramdisk/init.thunderg.rc file. I made this bit match the code in the build.prop. We'll see how well this goes here soon...

Code:

wifi.supplicant_scan_interval=20#(Replace 20 with 260)

I am moments away from flashing UD4 with the wifi fix incorporated.

Newbees, remember to use Notepad++ or other script editor instead of plain notepad. The language changed to script makes this stuff 100x easier to see and it also edits the script better from what I read about linux scripts. I speak from experience as a newbee myself!

You're getting errors in update-script because syntax in first post is for Edify,not Amend.

I thought about that last night. Unfortunately, wifi is still draining battery. I'm running Ubuntdroid4, & 3g runs very smooth. If I didn't run wifi so much at home & use internet primarily I wouldn't mess with it so much. Off to do some more research...

Can the rom be cooked to use edify? Then the script will work?
Will have to use clockwork to flash then?
