Hard Reset an Android OS?

Hey, im using this ROM (http://forum.xda-developers.com/showthread.php?t=905060) now and its fine, but i would like to hard reset the os (installed half of the market ) not rly but i tried very much and i wanna get a "brandnew" version of the rom.. is it possible to hard reset this rom, or do i have to install it again or how does it work? or do i hard reset like i would do with the custom 6.5 rom?

just wipe data, dalvik and cache. you can do this through the cwm menu. as far as i remember there is an option called "factory reset". it will wipe the data automatically.

what is dalvik? and what is cwm? and i didnt find something like a "factory/hard reset" in the settings

That's all stuff for NAND Android ROMs, if you are running Android from your sd card, just delete data.img from your Android folder (the folder with CLRCAD.exe and Haret.exe inside)

no, my rom is nand

Do you have clockwork recovery installed, or did you install a dft rom?
If using a dft rom, you can download the version of clockwork that will run from you sd card and use it to wipe your data and cache partitions, afaik. Sorry I don't have a link to it for you, but if you scour the stickies you should be able to find it

If you don't have CWM installed check out this thread
ClockworkMod Recovery for HD2 - v1.3
And in the thread of the rom your interested in,the op should mention which partition layout is needed to run that rom. And flash it via MAGLDR

if you have ClockworkMod Recovery then
1. Restart your device
2. Enter MAGLDR with holding down power button
3. Select "AD recovery mode"
4a. Optional but highly recommended take NANDROID backup:
- Select "backup and restore"
- Select "Backup" takes sometime (be patient while
backing up Dalvik cache)
4b. Select "wipe data/factory reset" takes sometime
5. Select "wipe cache partition" takes no time
6. Select "advanced"
7. Select "Wipe Dalvik cache" takes no time
8. If you don't want to preserve app. then also clear SD
9. Reboot with "reboot system now"
10. thats all

That's because this is the HD2 forum so of course the solution posted here doesnt work. Find the forum for your device and post the question there instead.

[Q] HELP PLEASE.. With changing roms..

Was just wanting to know that waht are the steps to be taken when changing a rom,
1. Wipe data/factory reset
2. Wipe cache
and do we even have to wipe DALVIKI cache???
do we have to do all the above three processes???
please help...

It's better to wipe the dalvik cache too.

Yes, and as a Precaution, I wipe /system too under "Advanced". BTW, if you are using a new version of Clockworkmod (3.0.2.4 or newer), it includes a "Wipe All (Dangerous)", which does all required for a fresh install, with just one click.

Can't Clean Dalvik?

Everytime when i open Clockwordmod Recovery to change a rom, every rom suggests to clean cache, clean Dalvik, do back up etc.
First time when i cleaned dalvik it worked.
The time after that, it completely froze on me. Since then, 4 or 5 roms later, i still can't clean my dalvik cache.
Also: After one of the roms, I no longer have the access to the 8th option in Mgldr. It says "invalid boot image sequence" or something along the lines of that, so I have to use the boot ad sd option instead.
Any help please?

You should task 29 before install other ROM

Or, in CWM choose "wipe data factory reset" which wipes all the partitions except system. (Therefore including the dalvik) then flash new rom.

[Question] What does it mean to "WIPE"?

I want to have a clean install on my Nexus, and I was wondering what it meant to "WIPE". Is it Factory reset, cache, dalvik cache, and system? Or is it also system too?
I have TWRP
Thank you!

factory reset. when you wipe data, you factory reset. that automatically wipes your cache and dalvik too.

Thank you so much for answering all my stupid questions. So If I wanted a new clean start for my phone (while it still being rooted and not losing all my SD card files) I would just have to do a factory reset, then flash?

Unfortunately, the terminology seems to vary from device to device and even from recovery to recovery.
It can mean either (a) "destroy the filesystem and rebuild a new blank one" or it can mean (b) "don't destroy the filesystem but delete all the files in it". In both of these cases, access to all files are lost, but there are subtle differences for the flash memory with regards to whether the blocks are marked as erased or not.
As regards to recent versions of TWRP, the "factory reset" button underneath the Wipe menu does not behave exactly like either of the above cases (although it is more similar to case (b)), nor does it behave the same way as the stock recovery's version of "factory reset", which deletes EVERYTHING in /data.
TWRP's version of "factory reset" erases everything in /cache, but when it comes time to deal with the /data partition, it avoids erasing all the files in /data/media. This is where the "internal SD card" files are stored INCLUDING ANY BACKUP FILES you might have made (if you didn't use an external storage for the backup)
Here's what I would recommend when using the Wipe menu in TWRP:
1) Put the tablet down on a table before you enter the Wipe menu - don't hold it in your hands. The reason for this is that none of the touch buttons require confirmation, so an accidental touch could lead to an immediate disaster involving loss of your backups.
2) If you are installing a new ROM from scratch, the only button you need to use is the "factory reset" button - nothing else. (Performing Dalvik wipe or Cache wipe are superfluous as the "factory wipe" button takes care of this) *1
3) If you are installing a ROM which is a small revision from a prior version - and the ROM dev has explicitly indicated it is OK to do a "no wipe" install, use only the "cache wipe" and "dalvik wipe" bttons. *2
In short, you should really only use the top four buttons in TWRP under normal circumstances. Especially you should avoid the "wipe data" button unless you are:
- selling the device or returning it
- some disaster happened where the /data partition fails to mount any longer.
*1 It is somewhat unusual that ROM devs fail to add a wipe of /system in their scripting prior to
installation; so typically using the "wipe sytem" button is not needed for new ROM installs, and it is cerainly not desired if you want to do a complete reset of whatever ROM is already installed.
*2 Doing this kind of thing is just asking for trouble - understanding and using the Titanium Backup along with full-wipe installs is a better idea.
cheers

Need help, erased data in TWRP now no files to flash

Stupid me, I think I made a boo boo, and need some help please.
I followed these instructions before installing a new ROM I wanted to test out;
Wipe In Recovery
-Wipe -> Swipe to factory reset (3x)
-Format data -> yes (3x)
-Advanced wipe -> check all boxes -> swipe to wipe (3x)
-Go back one menu -> Swipe to factory reset (1x)
I did all of that, went back to Install in TWRP, and none of my zips are at the bottom of the list anymore oops. Now what ?

Looks like you either have to download the factory image and flash it or use adb to push a rom to /sdcard/ in order to flash it with twrp.

I didn't realize that TWRP could load zip's now ? That's super cool .
I went to the Mount section in TWRP, and then plugged in my USB-C cable connected to the computer to the phone, and it recognized it, and allowed me to throw the ROM + GAPP files back onto the phone, I then rebooted Recovery, and they they were, F'ing amazing

What instructions were you following there? Oh so much wrong about that. You don't need to wipe anything three times, there's no point. You only need to go into advanced wipe, select only system, data, cache, dalvik cache, and wipe those. Then just flash your ROM. I have a guide here that you might find helpful:
