It has been mentioned with other devices that as JB is larger, the partition sizes need to be altered.
Therefore when flashing a custom rom on a Motorola Xoom should the extra step of formatting system and cache partitions (Recovery > mounts and storage) be done?

It is a necessity to wipe (data/cache/dalvik) and preferably format (system) if you are coming from STOCK or a different ROM..

Warning sd-ext2 is not formatted!
how do i format sd-ext2???
how do I go about clearing everything and starting again? there is a option in the wipe/format menu, called Wipe all Partitions (DANGEROUS!), does this clear everything? I dont want to do it without checking with experienced forum members first, so if you can help, please leave below....
You've got one solution
Make a backup from your sdcard on your PC, and format partition and increasing the size of three of them ( system, data, cache, sd_ext and ext2) with your recovery on EXT4.
Like this:
- system => Ext4
- data => Ext4
- Cache => Ext4
- SD-ext => Ext4
- SD-ext2 => EXt4 or Ext3
- sdcard => fat32
then, restore your files on your sdcard.

Use the EXT4 recovery as suggested, although are you sure that you'll need this space as the DS had over 1GB of internal user storage available to you by default. Mine has over 700mb free with all my applications installed.
The un formatted message relates simply to the non existence of the partition and isn't anything to worry about.
To wipe everything, the easiest way is to simply perform a factory reset, either from bootloader or from settings
The wipe all isn't what you are after as this is used by ROM cooks and wipes all partitions, which should only be used when installing new roms
Swyped from HTC Desire S using XDA Premium
I am curious about doing an internal data wipe before flashing a new Rom. I am using TWRP 2.5.5. I am on the 4.2 bootloader and am about to update to the new CROMi. I know that doing a factory reset wipes dalvik, cache, and system, am I wrong in thinking this still leaves some stuff left over on your internal SD? If it does, I want to format all of it. I have the 4.2.1 bootloader, the CROMi rom, and a 4.2.1 stock nandroid backup I made in TWRP all saved on my external SD. What I dont understand is if I format all the data on the internal, how will the tablet know what to do when I boot it back up? Will TWRP be lost? If it does boot back up, what will it boot back up to? I just dont quite understand this internal SD formatting thing so well, so I am asking for some help so I can avoid doing something stupid. I know this is possible because I have read about other people doing it in the CROMi thread, I just want to make sure I am not missing anything
Your tablet has the following partitions (and some others which are irrelevant for this discussion):
- Bootloader
- Recovery
- Linux kernel
- Cache partition (/cache)
- System partition (/system)
- Data partition (/data)
The internal SD card is an emulation that uses /data/media as storage. So if you format /data, that removes all user data including the contents of your "internal SD card" emulation. I don't know why the normal "factory reset" somehow deletes only the rest of /data excluding /data/media. It may be convenient but not what I would understand as "factory reset".
If you format /system (which is not touched by a factory reset), you won't be able to boot Android unless you install a new ROM before you reboot. You don't need to format /system, it's done by the CROMI installer anyway.

Aweomse! Thanks for helping me understand that a little better. My first ROM was CROMi 3.4.4 and I researched all this for about an entire week before I started this but I never fully understand the difference with formatting internal SD and factory reset. I have always installed the new ROM before rebooting anyway but it is nice to know CROMi does the system wipe for you. Didnt know that. If I were to do a complete wipe, would I need to install the most recent 4.2 bootloader prior to installing CROMi so it is there for CROMi to build on?
Oh, and btw your Kernels for CROMi are outstanding.

There is even official TWRP documentation about wiping: http://teamw.in/whattowipe
(I personally have never used any of the wipe options so far, so I am just repeating what I read about it)

There is no "wipe bootloader" option, so there is no need to reinstall the bootloader. Wiping the bootloader would also brick your device and you would need nvflash to recover.

Good to know. Glad I didnt attempt that. My firmware version was .30 so nvflash was not an option for me. Thanks again for your help.
I am a little confused on the terminology. I have done some searching and I came across the same question: http://forum.xda-developers.com/showthread.php?t=2107425 but it didn't really explain what manual format/system means for TWRP...
For instance, to install Slim Bean 4.2 build 8, it suggests to do a full wipe and then manual format system before flashing the rom.
How would I do this in TWRP? I want to make sure that this is DIFFERENT from format /data right? It is also different from "just" wiping "system" through "Advanced wipe" in TWRP?
Thanks in advance guys!

If you want to flash a new rom you have to go into TWRP
Wipe: Cache + Dalvik Cache + System
Wipe System is the same like formatting system

Thanks! Appreciate it. I was just wondering if formatting system is more of an active process that's different from wipe (eg. writing in zeros).

no its same
wipe = format
You don't need to wipe anything for flashing a newer version of some ROMs such as nighties. A factory is usually recommended to wipe the cache, dalvik cache and userdata to return the ROM to stock. Then when you flash a new ROM it will overwrite your current one.
Format System during SLIM installation
Hi,
Formatting the System is not risk the whole data i have on my device? in the past (as far as i remember,) doing it, deleted all the information i had on the device completely so it was even impossible to recognize it on the PC even all the drivers were well installed.
Looking forward for your advice.

glad I came across this thread, was always wondering about TWRP being so used to ClockWorkMod
does format data also wipe my android os As well?
Am currently on Crombi KK, looking to try out the Lollipop 5.0.2 Zombi-Pop Beta. I know just enough to be dangerous. Installed Crombi-KK to internal, then reinstalled to run ROM2sd a while back, SDcard set up in GParted. Have TWRP 2.8.4.0, just want some clarification on how and what to wipe. ROM thread states to do a full wipe, but I've never been totally sure on what constitutes a full wipe from recovery. From Wipe option in TWRP, there is Advanced Wipe and Format Data. Do I chose one or another or both? In Advanced Wipe, there are 6 partitions:
Dalvik Cache
System
Cache
Data
Internal Storage
Micro SDcard
What one(s) do I select? Since I'm running ROM2sd, do I need to run ROM2sd zip first?
TIA

A full wipe is a wipe of data, cache and Dalvik. In most cases that is sufficient moving to a different rom base and the default in TWRP under the Wipe menu.
If you encounter weird problems, format /data/ (and don't interrupt it. Takes 90 minutes or so!)
There are only very specific scenarios where wiping /system would make sense. /system gets formatted anyway during rom installation - no need to wipe it.
Internal storage - if you want to get rid of everything but do not want to format /data/. Wiping data wipes everything except /data/media/ in TWRP (that's where your personal files live). Wiping Internal Storage wipes everything including /data/media/
Micro SD - wipes your microSD or - in the case of data2sd/rom2sd - the fat32 partition thereof.
If you want to wipe/format your rom2sd /data or /system partitions, yes - you have to flash rom2sd1.zip first
Hello to everyone. Can anyone inform me about:
1. the exact commands in order to wipe all android partitions except /misc (/boot, /data, /cache, /recovery, /system).
2. the exact commands in order to flash two zip files (1. custom rom, 2. kernel)
3. is there anyway i can merge two android partitions specifically data with recovery because i don't want to use it anymore?
4. what exists after wiping a partition (unallocated space or allocated space)??
My device is HTC desire X UNLOCKED.
My purpose is to perform a clean install without using any custom recovery like TWRP or CWM.
Must have recovery
Got wipe then to advanced and click the box for cache do the wipe
Then go to install find your rom install it then find your kernel and install that then reboot

1. You need a custom recovery.
2. You need a custom recovery.
3. If you need the data from them just copy and paste them. Not only is it not possible without compiling Android, but it is not useful.
4. Since wiping is usualy done with mkfs (or even rm -rf) allocated space will be made.
