If you select mount/unmount.
What are those options used for?
Mount system. Sometimes that says mount sometimes unmount?
And when flashing ROMs do I need to go under and select format system? Sometimes, after flashing a ROM from clean, I still maintain system apps such as camera.

When CWM gives the option to unmount system that means its already mounted and vise versa. You do not need to format system when doing a clean flash, you just need to wipe data and wipe cache, and optionally wipe dalvik cache.
Actually a true clean flash does include system

For a full clean flash it is recommended to wipe /cache /data and /system
In regards to OP, when a directory is mounted it is readable. You may need to access files in those folders so they are mountable. Unmount to wipe.

idk why im confused. can someone please verify. want to flash erikmm rom
ummu - unmount system, mount cache, mount emmc, unmount sdcard?
is this what we want to see and leave everything else the same?
if we did have to flash stock rom. do we mess with these again?
Yep to your first question. And if restoring a backup you don't need to worry about them. Otherwise I'm not sure? Sorry.

Hey, I can answer your question
In erikmm's thread, he said:
erikmm said:
Installation Instructions:
1. Must have efs backup on desktop * just in case *
2. Nand Backup
3. Format System
4. Set Mounts to UMMU. *unmount cache, mount data, mount sdcard, unmount system*
5. Wipe Data/Factory Reset
6. Flash Rom
7. Reboot
8. Let the phone sit for 10 minutes then enjoy.

First, you want to flash this ROM. You should odin back to stock, and odin recovery ( for a full wipe )
Make sure Battery is full charged before odin these things
Second. Go to recovery. Volume up + Down + Power.
1.Backup ( of course )
2. After that, format system, try to format 3 times.
3. Go to Mounts & USB Storage
You'll see a lot of things. Make sure you check in this
unmount cache
mount data
mount emmc
unmount system
is correct.
If you see one of these option is different than erikmm said, you'll try to correct them. Ex: You see in CWM "unmount data", you can correct by press Power button to changed it to " mountd data "
And the same as another options
4. Make sure you correct right things in CWM. After that, do an wipe data/fatory resets ( 3 times, I think ) and flash erikmm's ROM in your SDcard
5. Reboot, wait for 10 minutes, and enjoy
Maybe the confusion is this... inside the "Mounts and Storage Menu" lists as follows...
mount /efs
unmount /data
unmount /cache
unmount /emmc
mount /sdcard
mount sd-ext
format /data
format /system
format /cache
format /emmc
format /sdcard
format /sd-ext
mount USB storage
+++++Go Back+++++
thus the UMMU stated is not in that order and what about the others?
Be safe and have fun.
You no longer need to mess with the mounts when installing erikmm's ROMs.
I'm on CWM 5.8.1.3, and about to flash Team PTSD's AOKP build 39 and then flash their new Chimera ROM over it (looks awesome guys).
I'm worried about messing up my phone (yes, I've obviously been fine thus far) but I wanted a bit more clarification on the actual steps one needs to take in order to flash a ROM. I know there are instructions that say things like
Wipe datax3
Wipe systemx3
wipe dalvik/cachex3
But the actual corresponding items in CWM are things like: Wipe data/factory reset, wipe cache partition, mount /system /data /cache,
format /data /system /cache.
So I've been assuming that wipe datax3 = factory resetx3 and wipe cachex3 = format cachex3 and wipe systemx3 = format systemx3. I don't know if I needed to mount any of them either. With the presence of the brick bug I thought it might not hurt to have someone expressly state what options to choose when flashing a new ROM (in the language used in CWM).
edit: ****, I'm sorry I thought I was posting in Skyrocket Q/A. Apologies mods

See, that's what I thought. The language is different though, and I wasn't sure if anything needed to be mounted before formatted.
So to reiterate. The steps, IN THE LANGUAGE ON CWM, are:
Wipe Data/Factory Reset x 3 (unsure of this)
Format Systemx3
Format Datax3
Format Cachex3
Wipe Dalvik Cachex3
Install ROM - Flash GAPPS
Reboot
Fix Permissions - Reboot
Yes that's it and its not a freaking language quit acting like its foreign to you its in English

I've been using 4EXT Touch Recovery to wipe/format before flashing certain roms. Is there a right way on how to wipe/format using 4EXT Touch?
This is how I do it (correct me if I'm wrong):
1. wipe date/factory reset
2. wipe cache
3. wipe cache + dalvik
4. wipe dalvik cache
5. wipe battery stats
6. format system
7. format data
8. format boot
9. format all partitions (except sdcard)
10. format sdcard
11. flash rom

If you are flashing an update of the same ROM do "wipe dalvik cache + cache" (in case the Developer has not clearly stated that the update requires full wipe)
If you are flashing a new ROM use "wipe all partition (except sdcard)" it will do all the wipes from the wipe menu, no need to repeat it
And wiping the sdcard every time you install a ROM clearly does not make any sense, you are deleting all you pictures, music and all other files that are not related to any ROM you are using

I didn't know that "format all partition (except sdcard)" is the same from 1 to 8. I'll try using it from now on every time I install new roms. Also, I thought that wiping my sdcard every time I install rom is to make that rom fully utilized/functional. And that is why I back up all my pictures, music, and all other files in my laptop. Anyhow, thank you for your simple but very relevant response.
There are some ROM specific files on the SDcard but a full wipe (all partitions except sdcard) clears them too

This is noted... Thank you for all the info's... Greatly appreciated! :highfive:
Tried to update from ICS to Sky_Jellybean and when I go to wipe cache etc. the cache says unmount /cache and the rest say mount ..
I can not get it to format/reset it just freezes on formating cache and then reboots phone out of CWM?
Any Suggestions?

Reflash cwm or use goo manager to install twrp
Sent from my SAMSUNG-SGH-I727 using xda premium
Hi Everyone,
For some reason, TWRP is not able to format /Data.
It keeps saying "failed to mount /data (Device or resource busy)".
This doesn't prevent me from updating the ROM to 4.4.2-21.
However, once updated it keeps on booting over-and-over.
Is there a way to - sort-of - a forced format of the internal flash.
Or at least the /data partition as it seems to be corrept.
Thanks - Will
Hi,
With twrp use the wipe menu for installing kk 4.4.2
Wipe cache-dalvik cache-data-system-internal storage (if you need a complete clean install), after install menu, flash the rom and the gapps, return to wipe menu, wipe cache and dalvik cache again.reboot.you`ll run on the new rom
(Ps : don't used mount sd and format menu).

Thanks for the (quick) response.
I'm coming from 4.4.2-19. However, on previous occasions I was able to upgrade without going through a clean install.
So I tried the same this time with 4.4.2-21. However, as it stands, this release tends to end up in an ever on-going boot sequence.
Even a clean install or going back to the previous version (4.4.2-19) doesn't work.
Compared to previous installs, the only difference I can see is an error stating that /data can not be wiped.
Any thoughts on this behavior?
Thanks - Will

Hi, which release of TWRP do you use ? in 2.6.3.0 and lower release, on wipe menu you have an advanced wipe menu, go on it select format and type data, this will format data partition

Tried formatting the data partition. It comes back with "failed" - no explanation.
Any other suggestion?
