From my understanding formatting the /system partition through CWM will remove the android OS completely from your device and you would have to flash a new one to replace it. Found the following information on the below website:
http://www.addictivetips.com/mobile...plained-boot-system-recovery-data-cache-misc/
/system
This partition basically contains the entire operating system, other than the kernel and the ramdisk. This includes the Android user interface as well as all the system applications that come pre-installed on the device. Wiping this partition will remove Android from the device without rendering it unbootable, and you will still be able to put the phone into recovery or bootloader mode to install a new ROM.
My question is, if I format the /system partition, does it remove all my currently saved pictures and videos on my internal memory? When I install a new ROM I typically wipe data /factory reset, then perform TDJs super wipe before installing the new ROM.
However, the instructions for installing the newest CM10 ROM also says to wipe /system partition. I know this will remove the OS, but will this also remove my pics and videos or should I back them up first before performing this step? Thanks.

Now i could be wrong as i am no Dev by any means but i do not think it will wipe your emmc as well. Reason i think it will be fine if you wipe /system is if you go in with root explorer and go to your /system folder your emmc is not located there so therefore if you were to wipe your /system patition it sould leave the emmc partition in tact.
But as always i would backup your emmc to your pc and give it a try. Hope this helps :good:

I was thinking the same thing as well but just had to ask because I have never processed the format /system action before. I am currently running a TW ROM ATM and looking through ES File Explorer my sdcard (which is the same as emmc on AOSP ROMs) isn't located located in the /system folder either.
Thanks for your reply, I tried to give you a thanks but I have reached my limit today

I'm no Dev either, but your right. Formatting system will not touch your emmc or sd cards. If you format system when flashing a new nightly (which I do every 3rd flash), you won't lose any user data at all. Only ROM and system apps, this is why you need to reflash Gapps as well if you format system.
When you use TDJ's wipe script, it formats everything (including system) except emmc and external sd cards.

Thanks so much, I run TDJ's wipe script with each install of a new ROM and completely didn't realize that is also wipes the /system partition. I just re-read his Superwipe thread and right in the OP it says
"This exceeds anything that CWM is capable of from the menu options. This will format and erase EVERYTHING on your /system, /data, /cache partions with EXT4 file system. It WILL NOT wipe SD CARD or EMMC... After it is complete with format and e****, it will align all disks partitions properly."
I was up extra early this morning, forgive me, I need to learn how to read better as well :laugh:
Thanks again.
Remember guys, wiping doesn't wipe everything. However, not wiping everything can bring its own issues.
Sorry for bumping up an old thread but it was very relevant to this topic. If I wipe the system before flashing a new ROM will my apps remain intact with their data? I know system apps will be gone but they will come back anyway so it doesn't matter.

Yes, they will stay intact with a /system wipe. However, with a factory reset or /data wipe, your apps will be gone.

I am no expert... And I use TWRP (you can get by downloading goo manager from the market)
I did a system wipe...
Which deletes all contents from your SD including previous back-ups
(so back up everything to a harddrive 1st)
The I used wugfresh to put the stock software back on
Then I flashed my desired ROM (Mmuzzy)

System wipe only wipes the /system partition and doesn't touch the sdcard, for future reference. If your sdcard gets wiped to something must be wrong.
Hello,
My first gen Kindle Fire has been setup in the OtterX format and has been running well on the CM STG7 ROM. I decided to update to the latest version last week and since then, my OtterX has not recognized the SDCard.
TWRP does see the SDcard and will view it's contents when browsing the file manager, but it won't mount the SDcard to my computer desktop. Nothing happens when I click the mount button.
When the OtterX boots, the System > Storage sees the SDcard and contents, but when I try to browse to it with a file manager, it says the path is invalid.
ADB shell sees the /sdcard/ directory and I can browse it from the shell as well.
I've tried formatting the entire device, including wiping the internal storage and formatting data (where you have to type in "yes") and nothing has resolved this issue.
Any idea what's going on?
I have had similar problem, rebooting a couple of this times seemed to fix.
But may need to reformat in twrp or do otter x partitions in bootloader

I'll try reformatting again.
My partitions became corrupted a couple years ago and I had to rebuild them manually, following a tutorial. OtterX partitions in the bootloader doesn't work on my device. I'm guessing it's because the partitions are spot-on with the sizing.
Do you know of a way to rebuild the partitions manually so they match the stock specs - maybe that way the bootloader partitioning would work?
Just restore amazon partitions in bootloader, reboot, restore otter x partitions.

For some reason after trying a different ROM (can't remember which one), I lost my SD card again and I can't seem to get it back. I even reverted the bootloader to FFF and did the "OEM Format", then followed the steps back to OtterX.
Attached is my partition table. I don't see a 'media' table, which is the SDcard, correct?
Any idea what else to do?
Otterx utilizes space that was already there, but reserved for the system. In order to better use available space for user data, the storage is placed elsewhere on the tree. The sd card should be located under storage on the otterx tree.

The strange thing is TWRP sees and accesses the SD card just fine.
I have a feeling the SD card isn't formatted in the correct format. Any idea how to format (or check/change format type) of the SD card through ADB?
Did you try the Repair file system in TWRP?
In OtterX Twrp 2.7.1.0 not 2.7.0.1
Wipe>advanced wipe
check data>current file system should be f2fs
tap Repair or change file system if you want to change back to ext4

Just checked the partitions with TWRP 2.7.1.0...
Dalvik Cache - Invalid partition selection
Data - f2fs
Internal Storage - Invalid partition selection
Cache - f2fs
System - ext4
I then formatted data as ext4 and the ROM still doesn't see the SD partition.

[HOW TO] Fix "Failure to mount" sdcard, system, data or cache
Hello.
I attempted to flash the Open Beta 7 (OTA_011) zip with TWRP to my OnePlus 3 and it broke everything.
The flash went normally, like with previous updates, but this time, I couldn't flash SuperSU over it. So I rebooted, hoping it worked.
I was presented by a "Decryption failed" screen, with the only option to factory reset.
The problem is, that I don't have any backups of my data, because FolderSyncLite aparently doesn't work at all.
When I got back into TWRP, my /data partition wasn't mounted, with the error
Code:
could not mount /data and unable to find crypto footer
TWRD shows the Data partition as 0MB. I know the data couldn't have just disappeared.
My best guess is that the userdata partition got corrupted somehow, and because it was encrypted, the entire partition is now useless.
TWRP's fsck.f2fs fails with error 255 (glitched error -1?), probably because it's encrypted.
Is there anything I can do to recover my data? Could I copy the raw partition to my computer and process it there?
Could I manually rebuild the broken header/footer? I still know the pattern/PIN and I don't think they're not salted.
I know there's some brilliant people on here. Please help.
Use the mega unbrick guide and everything will be fine
Edit: i didn't read that you're want to recover your data ... Hmm probably you can't recover your data anymore because your partition is currupted.
Look, change the data partition to ext4. It should work because sometimes the partition gets formatted to a corrupted form of f2fs. If it doesn't work, just wipe userdata and try again. It sure should work. Don't be shocked. Happens.
Thanks for the replies.
I tried a few more things, but the partition was beyond help. Full-disk encryption isn't very fault-tolerant.
I'll be using two sync programs from now on, just in case.

f2fs is for good benchmarks in real life ext4 >> f2fs
and when you change the FS the data will be lost .
f2fs makes twrp very slow as well .
I was using f2fs for a month and reverted it back .
Didnt like it
Its very easy brother although formatting data to f2fs will erase everything like your download's/pictures, so the steps.
BACK UP YOUR SD CARD FOLDER.
1 - Reboot to twrp
2 - select wipe and then select advanced wipe/change filesystem.
3 - select data
4 - select change filesystem or format ( forgot which word it actually says )
5 - select f2fs and swipe to confirm flash
6 - reboot and restore data folder
People will say its not worth it but if you write to your data a lot and install apps you notice faster install times over EXT4

There's no major difference you will see in changing the filesystem to F2FS. I am using F2FS on Data Partition on Sultan CM & there is no major difference in real life.

There are a few partitions on your phone, just like a hard drive. Think of your /system partition as your C: drive. Your /data partition would then be D: Your apps, the data for the apps, your dalvik/art cache, and your "Internal storage" are all on /data.
Changing your file system is literally formatting the drive, which initializes a new file system. For Windows, it's NTFS, for Linux it's normally ext4. You are basically going to format D:
Got it? Your Rom is on C:, data and apps on D:

About F2FS some users sad that it's better on gaming. And benchmarks (this it's useless).
Other than that recovery open slowly comparing with ext4.

You will see that youre internal memory it's smaller on F2FS.
