Android Full Wipe, The Correct Way.

[parin 857]

Most people come into custom roms and dont really *understand* what the

forums are saying to them in the terms of doing things the right way, often

things get misinterpreted as i understand but really you don't!!!

This is the case when it comes to custom roms installation, new comers

think yeah i'll have a go and go for it without even understanding the

basics of custom roms, wrong move, a little research didn't do anybody any

harm, and is time well spent when it comes to taking a gamble on bricking

your phone.

The main thing I've noticed is that people don't understand what a full

wipe is and just go with what they see...

Going into clockwork mode and just selecting wipe data, wipe delvic cache,

wipe cache, is not a proper full wipe, its like wiping your *** with ****

still in your bumhole untill you wash it, no no no, this method doesn't

remove the old system files, there still there untill you carry out a

format of the system partition, if you dont do this and install a rom over

it you will have problems with the rom you just installed.

The correct procedure for doing a full wipe is below.

[list=1]
[*]Go to clockwork mode recovery. Volume up, power button, and home button all pressed together for a couple of seconds
[*]Go to mounts and storage and select it.
[*]Go to format / system and select it. Scroll down to format system and select yes.
[*]Go to format / data and select it Scroll down to format data and select yes.
[*]Go to format / cache and select it. Scroll down to format cache and select yes
[*]Go to format / cache and select it. Scroll down to format cache and select yes
	That's it no need to format anything else, just go back and install the rom
[/list]
from sd card.
This is the correct way of doing a full wipe everything is erased and
formatted ready for the new rom, no old system files etc....[/CODE]

Thats right .. same is seen in QBKing77 You tube video... I learnt from that ...

Also doing it three times does full format .. for e.g: in windows we do quick format .. full format....

[KapilAgrawal 340]

100% of reputed Cusom ROM makers format /system in their script (updater-script) before they flash new System.

ui_print(" Formatting System...");

format("ext4", "EMMC", "/dev/block/mmcblk0p25");

mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/system");

and I would strongly suggest guys to make sure that the custom rom you are going to flash will work before you format /system. In case you have formatted /system & the custom rom does not work for any reason. You will have to RUU/SBF the phone. So beware.

Thanks Parin. Well with custom ROMs offering various flavours of Gingerbread and Icecream Sandwich, this is welcome info indeed!

Thanks parin bhai..That's why i use 4ext recovery which has an option to 'format everything except the sd card' :-)

Nice info for beginners.

You only had to ask, but i guess that was to hard to do!

I believe that the following might be better (just copied this suggestion from another place):

switchoff then press only home button and power button

1. wipe data/factory reset.[imp]

2. wipe cache partition.[imp]

3. Go to mounts and storage and format these :

a. system

b. data

c. cache

d. sdext

4 go to advanced and then in there format :

a. Dalvik cache

b. Battery stats [not imp.]
