-: Installing ClockWorkMod custom recovery :-
===============================
Some new Android users may be wondering, what is ClockWorkMod Custom Recovery Image?
They can go here and find their answers:
What is ClockWorkMod Custom Recovery and how to use it on Android?
First, Your phone must be rooted.
If it's not rooted, use above guide of rooting.
1. Required downloads:
----------------------------
Step 1:
First, Download this all-in-one RAR file: Recovery Tools.rar
The RAR Archive contains:
1. Fast Boot (folder)
2. flash_image
3. recovery.img
4. MD5 Hash.apk
Step 2:
Now extract the archive and copy all files (except Fast Boot Folder) to the root of your phone's SD Card (i.e. /sdcard/) and install the MD5 Hash(MD5 Hash.apk) application.
2. Checking the MD5 Sum of 'recovery.img' file:
--------------------------------------------------
Now you must check the MD5 Sum of 'recovery.img' file.
First, What is MD5 Sum?
Answer: MD5 Sum of a file, is a string / series of characters that is used to check whether the file is corrupted or not.
Step 1:
>> Use MD5 Hash to do it.
>> Open MD5 Hash and select Calculate MD5 from file
>> Now click on ... button, browse to /sdcard/recovery.img and press 'Select button'.
>> Then click on Calculate MD5.
Step 2:
Compare the calculated MD5 with this MD5 Sum: 258e95cd2a697d902c2c139893d83063
(Now see if both the sums are same. If not, download the recovery.img and try checking MD5 again.)
REMEMBER, BOTH THE MD5 SUMS MUST BE SAME OTHERWISE YOU AND YOUR PHONE WILL DIE!!
(Different MD5 Sum means the recovery image is corrupted.)
3. Flashing the recovery image:
-------------------------------------
====Method 1: Using a Microsoft Windows based Computer====

Tips and Warnings:
==============
Tips:
------
Tip #1: Install Busybox:
Busybox is a wonderful collection of UNIX Operating System's useful tools. It's a must!

Tip #2: Nandoird backup:
Now you are rooted and have a custom recovery image installed.
Means you have access to file system of Android.
So, any system file can be accidentally deleted and it can cause a fatal error or worse!
And you know, taking a backup is always a good habit.
You can also backup whole Android system!
To do so, boot into recovery, then go to Backup and restore and select Backup.
Now whenever you experience any problems with OS, you can reinstall your OS by restoring the backup!
Tip #3: Uninstall some crappy system apps:
You can use Root Explorer to do it.
System apps' APKs are located at /system/app
Recognize the app you want to uninstall by its icons.
Put '.bak' behind the '.apk' extension.
For e.g., To uninstall Finance, rename it to Finance.apk.bak (orginal: Finance.apk)
These apps are safe to uninstall:
1. LG Remote Call
2. Email (not Gmail)
3. Finance
4. LG World
5. Smart Share
Whenever you want any app back, just remove .bak and you're done!
Warnings:
------------
Warning #1: Factory Reset
You have installed recovery image so you need to be very careful!
NEVER USE PHONE'S BUILT-IN FACTORY RESET OPTION. IT'LL BRICK YOUR PHONE!
If you need to perform a factory reset, it's available in recovery.
Warning #2: Bad Message "recovery "
Every time you'll boot into recovery, it'll give the above error!
Hey! Don't doubt yourself! You just flashed it fine!
Yeah, that's also a standard error. Just ignore it.
All the Best.
