    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 clockworkmod and just selecting wipe cache, wipe data/factory reset, wipe dalvik cache is not a proper full wipe, its like wiping your ass with shit still in your asshole untill you wash it, no no no, this method doesn't remove the old system files, they are 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.

    Go to clockworkmod recovery.

    Volume up, power button, and home button all pressed together for a couple of seconds.

    Wipe the cache partition

    Go to Advanced and wipe the dalvik and batt stats

    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.

    Now go back and install the rom from the internal or external 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, old kernel remnants etc....

    No need to wipe data/factory reset, and your internal and external sd cards remain untouched.

    You can install any Rom using this method, no need to go back to a stock base via Odin, you can go from GB to ICS or GB to JB, or ICS to JB or visa versa, any combination you like, it won't brick your phone, i use it all the time and always a smooth flowing Rom running sweetly.


    Have a nice day.

    When you say "etc" meaning that all the data will be wipe within the phone memory? All the pictures and mp3s and game files will be deleted

    Hi, no, all your personal files are 100% safe, this full wipe will not wipe the internal sd card and will not wipe the external sd card, all your pictures, mp3s, videos and anything you have downloaded will still be there when you install your custom rom.
    However what it will wipe is the first 2gb partition which holds the operating system and all personal user data like your contacts, bookmarks, APN settings for Internet access, accounts etc...
    If you do a Titanium backup of this personal user data it can be restored after you have installed the new rom.

    I will post a guide on how to do this.

    That's awesome, going to do that next time! :D
    Explains a lot about the problems I've faced after flashing a new ROM just using the 'wipe' and not your 'wash' method. :p

    So you are saying that using the "wipe data / factory reset" option on the Clockwork Recovery mode, will not do the same steps as doing manually :

    • format /system
    • format /data
    • format /cache
    Interesting point.

    spider, you are right... The wipe data, only does a /data format.
    Thank you for the tutorial and suggestion.

    Just for clarification: does the "format /cache" and "format /data" from the storage menu preform the same task as "wipe data / factory reset" and " wipe cash" from the wipe menu? When I flashed check rom 6 I used the wipe data, wipe cash, and wipe dalvik but cant remember if I wiped system files since I was using an older version of CWM. All though its running fine im going to re-flash following your guide.

    Storage Menu
    format /cache
    format /system
    format/data

    Wipe Menu
    wipe data / factory reset
    wipe cash
    wipe dalvik

    For peace of mind, can you explain the difference between the two different wipes and for which purpose you would wipe vs. format.
    I thought I had all this down but now am confused. Full wipes use the storage menu? For flashing new kernels, mods, themes use the wipe menu?

    The difference between the two wipes is the wipe your used to doing is kind of like a semi wipe not a full wipe, the wipe you normally use dosent format the system partition, the old system files are still in place until the system partition is erased and formatted, and what YOU do is install the new rom files over the old system files.

    The wipe method i use is the system files are erased and the system partition is formatted ready for the new rom, meaning no conflicts with old system files etc, resulting in a smoother flowing rom with no issues or conflicts.

    Its the same for the data and system cache, when formatted everything is 100% erased, impossible to have issues afterwards, where as the wipe dalvik cache, wipe cache, and factory/reset might have issues afterwards because although you have wiped them, the data contained within is still there your just installing the new rom on top, like an overlay, unless the system partition has been erased and formatted, there may be trouble ahead.
