[Q] Full wipe before installing a ROM?

Hi, i were considering installing the nFinity 1.06 Gingerbread, when i see he recommends during a full wipe before installing.
Should i just do a factory reset or what?
If i'm wrong could anyone explain?
Thanks

I'm not an expert but normally you install the ROM and the you wipe data and cache.

1.Reboot into xRecovery and make a back-up of your current ROM. (You'll need a working xRecovery or else it will say Device/SD Card busy).
2.Wipe the following in xRecovery:
Factory Reset (Full wipe)
Wipe Cache Partition
Wipe Dalvik Cache
3.Go to install Custom Zip

i hope it helps

Ehm jea im kinda new to this stuff so a couple of questions:
I got an backup of my ROM so how do i reboot into xRecovery?
And will all apps be gone? cause i thought u need ROM Manager to install? (or could use)

ROM manager is too unreliable, stick with manual recovery, apps will be gone so back them up first with Titanium Backup and restore them after flashing new rom

Uhm okay got a link for a tut or something?

titanium backup can be found on the market (but its a paid app)
astro file manager (a free app) can backup your apps (although i recommend titanium backup as it allows you to backup more than just your apps)

Well never mind got my ROM installed

installing rom question

Do you have to backup to stock rom or can you just install a rom on top on another without backing or w/e?

You should backup your rom before flashing, this way if anything goes wrong you can go back.
You should always wipe, wipe, wipe.
Wipe data/factory reset
Wipe cache partition
Go to Advanced and wipe Dalvik Cache
After the wipe go back and Install zip from sdcard. After install I do another wipe on the Dalvik Cache then fix permissions. Remember Wipe, Wipe, Wipe.

so as long as I do that then I can install a rom over another and delete the previous one while doing so?

I recommend making several backups.
First, make sure you have Clockworkmod installed via nvflash. Then make a backup. Download the backup to your pc for safe keeping (just in case things go wrong).
Use Titanium Backup (free version works, but buy the full one if you like it). Use the batch feature to back up all user apps. Do not back up system apps.
When installing a new rom, especially roms that use different versions of android, you should wipe everything you can except the external sd card (where you keep your backups). Wiping "system" is important.

Does wiping data/factory reset erase nandroid backups?

If I have a backup on the internal sd card, when wipe data before flashing a rom, will that delete my nandroid backups? Don't know if I should backup my roms to internal storage or external.

Wipe data won't delete your nandroids on the internal but Odin a stock ROM and you will loose them... all of them.
I now backup on a weekly basis and transfer what need to extSD when I'm thinking of doing something potentially dumb.

LOL at "potentially dumb".
Couldn't have put it any better myself. I use the same procedure, I make a weekly nandroid to the internal storage & then copy the backups to both my 64gig card & also to my PC occasionally.
I can't make a nandroid directly to my 64 gig card as I won't format it to FAT32 because of some of the restrictions of FAT32.

Not true...IF you wipe data/factory reset from stock recovery, it reformats the whole internal sd card(everything is wiped). Now if you wipe data from cwm recovery, then no nandroids are not deleted. Also odin does not wipe internal sd either...again you have to boot into stock recovery and wipe data/factory reset to reformat internal sd. I still always back my nandroids up to external sd, just incase my internal ever corrupts, I wont lose them!

Ahh yeah, that makes sense. That's how it was on my nexus with being just internal storage and nandroids never were deleted. Thanks for the clarification.

There's something in Odin that wipes it because when I used it to go back to stock it wiped mine...
Either way though, backup your nandroids to your ext card... saves you all the hassle lol

Does not erase backups unless they are stored internally by default

I can see the stock recovery wiping it but since the OP used the term nandroid I assumed CWM. Good to know the stock wipes it clean if there is ever a time I have to send it back.
I had an issue back before we were unlocked and when I ODINed back to stock all the internal SD was wiped. Wasn't too pleased but my fault for not backing up.
Sidenote about backing up. I tend to backup the entire internal and external SD every Sunday. The app I use for backup doesn't see the S3 as a media device so I can't use it to make incremental backups. Is there any program that would do that? I use karens replicator for backup btw. That's the one that doesn't work.

I need to clear it - I made "wipe data/factory reset" in stock ICS recovery menu - is it going to cause deleting ROM (and reboot will make brick) OR just wil get it back to clean factory ROM?
I found few threads here about "wipe data"-thing, but it seems to me, that every version of Android / custom ROM / recovery type could behave different.
My device is Thinkpad Lenovo tablet (rooted) with Android 4.0.3..my apology by writing in here, but I'm a newbie on this forum and that's why I can't write in some threads, including more relevant ones.

Well, in the recovery for our device that would just wipe the data and not the ROM. I use TWRP

Clean install

Hi.
I use a custom rom and I want to change to Purity. I want to make a real clean install, to clean every useless stuff on SD card.
I suppose I need to do a factory reset and wipe system partition.
But I prefer check here before.
Thank you.

Backup what you want to keep on the SD card, then run the factory image following the guide on here to the T. You'll then be 100% stock with a clean, stock ROM

Hi,
The rom has nothing to do with your sdcard (this part of the storage), I mean a clean install is with a full wipe: Wipe Data/Factory Reset and Wipe Cache Partition/Dalvik cache, no need to wipe the sdcard, but if you want....

Does factory reset in twrp delete the backups?

So I'm on twrp recovery (rooted Oneplus 3T) and i do a lot of moding which often results in bootloops, so I resort to my backups made in twrp. I was wondering if I'm doing a clean flash of a new rom and it fails, do i still have the backups?

Factory reset wipes only Data , Cache , and Dalvik.
If you select Advanced Wipe and then wipe the Internal Storage or select the option Format Data from the Wipe menu then you will lose your backups (and all your personal data too ) as they are located in Internal Storage/TWRP/Backups.

What if you selected Factory Reset from Android Settings? Does that delete the TWRP directory (folder) and its contents as well (which contains the Nandroid backups)?

Yes, if your TWRP backups are stored in internal sdcard, factory reset from settings will wipe the internal sdcard and remove your TWRP folder and the backups contained in that folder.
BUT...
If your backups are stored on external sdcard, they will not be wiped by factory reset from settings, they also would not be wiped by factory reset from TWRP.

Yeah... If you don't have SDcard, make sure your NAndroid backups or ROMs are backed up on your PC or external hard drive. Otherwise you cannot install/flash your new ROM which includes the android system.

Or, you could just factory reset in TWRP, factory reset from within TWRP does not wipe data/media, otherwise known as user storage partition where the TWRP folder is stored, therefore, any TWRP backups stored in the TWRP folder in your internal sdcard will not be wiped by the factory reset process from within TWRP.
However, factory reset in TWRP does wipe data/data partition, where user settings and user installed apps are stored. If your ROMs are also stored in the data/media(user storage partition), they will not be wiped by the factory reset process from within TWRP either.
