Q) How to flash the kernel
A) Just apply update.zip from Recovery or flash tar file using ODIN.
Q) Will i lose my data if i flash kernel?
A) No, you wont lose any data nor do you have to wipe data or cache.
Q) Does my battery need to be 100% to flash?
A) Not at all
Q)Flashed CM 6.2 Kernel on Froyo Rom and WIFI doesnt work?
A) There are two versions of Kernel. One is for Froyo Rom and other is for CyanogenMod Rom 6.2 (CM 6.2). if you are on Froyo rom and flash CM 6.2 then your wifi wont work and vice versa.
Q) 1400 Mhz (Extreme version) doesnt work for me
A) Not all Galaxy 3 suppport overclocking as high as 1400 Mhz. If it doesnt work then keep frequency lower or flash Ultimate, Performance or Lite version
Q) What does this data2sd in g3mod do?
A) data2sd is method by which all your /data partition goes to your sdcard thus giving you more space for downloading apps. Its suggested to use data2sd only if your sdcard class is higher than Class 6
Q) Internel Memory shows 0kb
A) Check if you have fs.data2sd at this location /sdcard/Android/data/g3mod/ If yes then delete it or else your sd card doesnt have sd-ext partition
Q) How can i go to recovery mode
A) Press MENU+VOLUME UP+VOLUME DOWN+POWER button and bingo!!!
Q) Should i use multi boot even if i am having 2 gb card class 2 ?
A) Sd card with any class can use multiboot
Q) Data Wipe Necessary When Switching Between CM and Froyo ?
A) Yes data wipe is necessary for switching roms between CM and Froyo. But we have given option to Backup data also in recovery.
Q) My APP is not working after Flashing KERNEL
A) Its not a kernel problem
Q) What is tun.ko?
A) It is basically used to setup Open VPN connections
Q) What is jhash3?
A) jhash3 improves the HSDPA/3G/EDGE speed
For Advanced users
Q1) Battery is draining fast?
A) After flashing the kernel please calibrate your battery or else let 3-4 full battery cycles pass.
Q2) Which profiles should i use?
A) Lets take example that you are using Ultimate kernel. Keep the governor ondemand (Like every good boyfriend fulfills all demands of his girlfriend ondemand governor does the same for your CPU ).
Make profiles:-
1) Time Profile - 12 am to 6.00 am Freq 100 Mhz to 400 Mhz Priority 100
2) Screen Off - Freq 100 Mhz to 600 Mhz Priority 95
Q3) What are advanced settings in the SetCPU mean?
A) Sampling rate is rate at which the frequency of your CPU changes. Up Threshold is limit at which CPU will change freq on load (Scales Up). Down Threshold (conservative only) is limit at which CPU will change freq on load (Scales Down). Powersave bias is used for saving the power of CPU, it will slow down the CPU and affect the performance also 200 in powersave bias mean 20%...250 means 25% and so on.
Q4) I want performance and also good battery what profiles should be i use?
A) Refer to Q2 for Profiles Set up and now go in Advanced tab and Keep Sampling Rate 10000 or 15000. Upper Threshold to 90 and Powersave bias to 200 (20%). Since we are using powersave bias, this will affect the performance as it slows down the CPU so to increase the performance we are lowering the Sampling rate thus we get perfect balance of Performance and good battery backup.
NOTE: ABOVE SETTINGS ARE JUST EXAMPLE..PLEASE PLAY AROUND AND CHOOSE SETTINGS WHICH SUITS YOU THE BEST
If you want to donate to the team as a whole, please divide the amount and donate separately to each member. Sorry for the trouble caused.
Thank You for considering to donate.
1) Flash Kernel v1.7+
2) Go to CWM Recovery -> Multiboot -> Backup ROM.
3) Backup your Current ROM to ROM1 (It will backup the system.img at /sdcard/Android/data/g3mod/roms/romname_ROM )
4) Add the system.img of your 2nd ROM to /sdcard/Android/data/g3mod/roms/romname_ROM and similarly for different ROM's.
5) Use the CWM Recovery -> Multiboot -> Switch ROM option to switch between different ROM's.
6) If switching between Froyo ROM and CM6.2 RoM, you will need to wipe data and also change kernel's via update.zip method.
7) Use the data backup and restore option to prevent loss of data when switching between Froyo and CM6.2 ROM's.
Note: Ask the developer of the ROM's to provide you with the system.img for their ROM
How to use Hybrid Data2SD
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo hybrid > /sdcard/Android/data/g3mod/fs.data2sd'
4) Create a text document in Notepad with a list of all the directories you wish to move. Example:
Code:
app
log
dalvik-cache
---LEAVE A BLANK LINE AT THE END---
5) Save the file and call it 'data2sd.dirs'
6) Do 'adb push data2sd.dirs /sdcard/Android/data/g3mod/'
7) Reboot your phone
8) Once your phone has booted, run 'adb shell cat /data2sd.log' to ensure it is running correctly.
How to enable Multi Data
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo 0 > /sdcard/Android/data/g3mod/multiosdata'
4) Multi Data will automatically backup your data upon booting into a different OS.
Make sure to not wipe your SD-EXT partition. Doing so will erase the backups from other firmware. Only wipe it if you wish to erase data for everything.
You can also use Multi Data to quickly restore data if your phone has become corrupted. It will restore it back to the last multi-boot switching
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo 0 > /sdext/lastos'
4) Reboot the phone
//Kernel dir
__system("mkdir /sdcard/Android/data/g3mod/kernel/Froyo");
__system("mkdir /sdcard/Android/data/g3mod/kernel/CM6");
__system("mkdir /sdcard/Android/data/g3mod/kernel/CM7");
How to configure compcache:
If you want to use default configuration (as up to now.. 62 MB aprox.), you don't have to do anything different as what you have been doing. But if you want to use a more/less memory, here are the steps:
Inside that /sdcard/Android/data/g3mod/compcache file, write ONLY the number of MegaBytes you want to use for compcache.
Reboot.
If compcache file is empty or contains a "0" inside, it will use default configuration.
How to: BLN
This is only "needed" if you have a i5801 | i5800L or any other Galaxy 3 model with back button lights and want BLN in it.
How to install:
First, download the lights.GT-I5800.so file from google code. Then execute this commands:
adb remount (or if this doesn't work: mount -o remount,rw /dev/stl6 /system)
adb rm /system/lib/hw/lights*
adb push [Location of this file] /system/lib/hw
After that, reboot and now you have BLN working
Steps for Changing the Max Freq(Dynamic OC):
There is an entry in /sys/devices/system/cpu/cpu0/cpufreq/plls_table where you can put your own value for APLL.
Before doing this, set "PERFORMANCE" governor on and min and max frequencies to the maximum.
Code:
// Do this in adb
echo "0 a2580301 a14d0303 c07e13fc cf850240" > /sys/devices/system/cpu/cpu0/cpufreq/plls_table
You need to replace the 258(Hex Value) with your desired value.
Here 258 means
(2*16*16) + (5*16) + 8 = 600
and 3 means it is 600*2 = 1200
Therefore, a2580301 means 1200MHz.
This is a temporary method. For a permanent Method, add this line to a init.d script. Name the script to something like S10_Dyanmic_OC.
We willl add different features as and when we can implement them.
The main goal of this kernel will be to keep the phone stable and fast.
There will be nothing as alpha or beta releases.
We will give out the kernels directly, but if anything goes wrong and you have to reflash the ROM or kernel, please dont start shouting.
You may give us different ideas on what features to implement. We will try our best to implement all the features you want
Many of the features implemented in this kernel, are taken from marcellusbe's Fugumod Kernel, and we shall be ever thankful to marcellusbe for the fugumod kernel
Warning: We are not responsible for any damage caused to your phone (softbrick or hardbrick)
marcellusbe for all his help, awesome fugumod kernel supercurio for voodoo v10 Paolo for BFQ I/O Scheduler All developers for making this an awesome phone Everyone who is helping is solving different issues with this kernel Please let us know if we miss anyone ...oh we did already miss someone..thanks G3MOD TEAM too
