M_A_H official android trick

• Android Gingerbread 2.3.x
• Note: Only the main CWM (ThunderBolt! CWM.zip), screenstate_scaling, libsqlite is ICS/JB compatible.
• At least 3MB free on /system (Delete unused ringtones or useless apps like Aldiko/Allshare etc).
• Root.
• Kernel that supports init.d.
• CWM recovery to flash CWM zips.
• Ext4 filesystem if you want to use the remount script.

• The 3G CWM is an addon that in most cases improve your mobile wireless speed. Only compatible with GB I9000.
• The libsqlite CWM is an addon that removes the need to fsync before a database write is done. It'll improve database write speeds (where apps like SMS, contacts etc use databases).
• The LMK addon strives to maintain an effective LowMemoryKiller so that you have a small degree of multitasking coupled with a huge performance boost and a phone that lasts for days without needing a reboot to "clear off the memory or something". The higher the LMK value, the less multitasking capability you get. You'll get more performance for it though. Not compatible with CM10/CM10.1 and stock JB.
• The screenstate_scaling addon will perform VM scaling and governor tunables scaling to get the best of battery life and performance.
• Touchscreen tweaks in /etc/bolt_scripts folder are only for i9000 GB in bolt_scripts.
• sqlite_optimize in /etc/bolt_scripts folder optimizes and defrags all sqlite3 databases in your phone.
• remount script in /etc/bolt_scripts remounts the partitions in your phone to optimize its performance at the expense of some risk of corruption.
• CFS scripts in /etc/bolt_scripts folder to optimize performance. Choose the default (S98CFS)one if you have no problems with it.
• drop script in /etc/bolt_scripts to drop caches.
• s91ecn script in /etc/bolt_scripts to disable tcp_ecn.
• TCP_Buffers script in /etc/bolt_scripts to increase TCP buffers for better network performance.

• If you're using a custom MP3/Wav file as a ringtone, flashing ThunderBolt! might erase that setting causing your ringtone to be silent. Be sure to restore the ringtone again.
• Barriers are turned off in /data. Corruption can happen but risks are minimal if you still have journaling.
• Libsqlite safety_level is tuned to "1" from "3". There is risk of corruption here. Revert the libsqlite*.so files from the restore pack if you face corruption This is due to no fsync is done before databases are committed into disk hence it'll be faster but at the risk of corruption i.e. Launcher widgets going missing or SMS messages going missing etc.
• sqlite_optimize script will produce errors like "malformed database" or "unknown collation sequence". It's normal, it means that these databases are not sqlite compatible, hence erroring out (skipped).
• You may sometimes lose access to busybox. Install busybox installer (stericson's) from the market and install 1.19.3 or higher to /system/xbin.
• Bootup (even to the point where you can see the launcher)may be a little slow as zipalign takes some time. This is only if you're loading zipalign on startup.
• remount script has to be launched using script manager
• Remount script is only for a few phones (check /etc/bolt_scripts). Let me know if you want one added for your phone.
• The LMK/OOM is on the aggressive side. Some apps that you've hidden behind other visible processes SHOULD be killed to make way for bigger apps. This is to ensure your Angry Birds or Fruit Ninja doesn't LAG LIKE HELL after some time.
• On CM/AOSP and stock JB , the Android OOM/LMK will be set by the system right after the OS boots. Hence, we can only touch the Linux LMK. Modifying only the Linux LMK will result in a mismatched LMK. Even modifying the services.jar will cause mismatches in the lowMemory and LRU flags. Hence it is better not to mess with it and let the OS handle the LMK setting.

1. Copy the CWM zip and all the addons you need to your sdcard (internal or external, as long as CWM can access it).
2. Install using CWM all the CWM zips without needing a reboot in between
3. Wait for bootup
4. Open up Script Manager and launch /etc/bolt_scripts/remount[device] (e.g. remounti9000) as Root (The skull icon) and as Boot (The wheel icon).
5. Open up Script Manager and launch /etc/bolt_scripts/sqlite_optimize as Root (The skull icon). This script can be used arbitrarily at anytime that you want. Don't load it as boot or copy it to init.d though, it'll significantly slow down your boot up as the script is a very long running script.
6. Open up Script Manager and launch /etc/bolt_scripts/s70darky_zipalign as Root (The skull icon). This script can be used arbitrarily at anytime that you want. You can copy it to init.d and setting its permission to rwx-rwx-rwx. I moved it to bolt_scripts so that first boot for some people won't be slowed down.
7. Open up Script Manager and launch /etc/bolt_scripts/CFS/S98CFS as Root (The skull icon) and as Boot (The wheel icon)..
8. Open up Script Manager and launch /etc/bolt_scripts/S98TCPbuffers as Root (The skull icon) and as Boot (The wheel icon)..

10. PROFIT

• To revert ThunderBolt!, download the ThunderBolt! Restore.zip
• Do note that reflashing your ROM will remove ThunderBolt! as well.

• Repackaging ThunderBolt! into custom ROMs is allowable as long as it is included as a feature of the ROM as well as proper credits are included.
• Please reply into the thread if you would like to include it as its just a nice thing to do 
• You are free to modify the contents of the scripts, but please make it known that you've modified it and also briefly include the modifications you've done.
