    This is based on the IHO recovery but others are similar.

    This assumes you are already in recovery, I also highly recommend making at least a Nandroid backup in case something goes wrong (which can happen but shouldn't).


    To clean your personal information:
    Select “wipe data/factory reset
    Select “yes”


    To install over a rom without losing data such as updating from 2.0 to 2.01 with a complete rom.
    If it is labeled as an update, using this will wipe out your install as it wipes out the system files. Updates should be just put in.
    Go to “mounts and storage”
    Select “format /boot”
    Select “yes”
    Select “format /cache”
    Select “yes”
    Select “format /system”
    Select “yes”
    Back out of that menu to the main one again and select “advanced”
    Select “Wipe Dalvik Cache”
    Select “yes”


    To wipe clean 100% and install a new rom
    Select “wipe data/factory reset
    Select “yes”
    Go to “mounts and storage”
    Select “format /boot”
    Select “yes”
    Select “format /system”
    Select “yes”
    Back out of that menu to the main one again and select “advanced”
    Select “Wipe Dalvik Cache”
    Select “yes”

    Thanks for this very helpful information. Are there instructions anywhere on how to use Titanium Backup to backup/restore as much as possible between updates? The most annoying thing about updating the ROM is getting all my system settings (accounts, interface settings, etc) back to their previous state.

    The user app+data backup and restore is straightforward, but I never know what to do about system apps and settings.

    Dont restore system apps+data. Those were recreated when you booted back into the phone. Things change each time you flash so restoring those can cause issues.

    I haven't had trouble with restoring apps and data too much, however I do not use Titanium Backup, it has caused me some problems.

    I use MyBackup Pro and restore apk's then data in a two step process. Doing it as a single operation has been known to create problems with certain apps. This technique works on TB as well, however TB is more of a hassle and too easy to restore things you shouldn't.

    Never restore system settings, that is one thing certain to mess things up.


    If you look in Harmonia 2's thread there is a link to my guide on backing up and restoring.

    Does it matter with /mount system?

    You don't need to mount or anything, just use it as described.

    I followed your instructions for a 100% clean wipe, but then instead of flashing a rom I accidentally rebooted and now I'm stuck in a blue fastboot. Ugh.

    Suggestions? I have no idea how I got here or what to do.

    Just pull the battery and boot back into recovery, via holding down the back button, the volume down button, and the power button at the same time... then flash the Rom you meant to dash(:

    Oh my gosh, thank you so so much! I just spent 2 hours looking up bizarre, complicated instructions that weren't helping me and that's all I needed to do...wow.

    THANK YOU AGAIN! I owe you my life and this whole night's sleep

    Thanks so much...but I think I just made it a lot worse. My SD card was wiped so I couldn't access the rom I wanted to flash...so I did LG style factory reset, and now I get the blue fastboot screen, but when I told down those buttons instead of going into recovery I get 'android system recovery' and it just reboots.... and back to the blue screen....
    ahhhhhhh!

    Never do a factory style wipe. Guaranteed brick. But if you can access adb then your in luck. Check the stickies

    When I go to Mounts I get:

    Mount /system
    Unmount /cache
    Mount /data
    Mount /sd-ext
    Mount /sdcard

    No Format commands. Do I have to look somewhere else for the Format commands?

    great guide. also to add to list of good backup apps,might want to try app backup & restore. its super simple to use,and as long as you have a decent file explorer you dont even need app backup installed to restore the apps saved with it.

    LeslieAnn,

    The update instructions in your original post say to wipe

    boot -> cache -> system -> Dalvik

    but the total wipe/clean install instructions say to wipe

    data/factory reset -> boot -> system -> Dalvik

    When doing a total wipe, does the data/factory reset wipe include wiping the cache? Is that why "wipe cache" isn't listed in the total wipe instructions? Just curious. Thanks.

    Yes, cache is done during factory reset.
