Formatting system

Noob question... What will happen when I format system. What will I lose and keep. Will my internal storage get lost? And will I have to push new rom back to phone via usb transfer. I do understand wiping data, both caches, and system, but what does formatting system do.?

Your ROM is installed on /system. If you wipe system you wipe the os. It doesn't touch the data or internal storage.

no. no you dont.
wiping /system just erases the /system partition.

Thanx guys... I think I'm good. System wipe/format system will not erase data. But a data format wipe you lose everything. That's what I thought but wanted to double check so I didn't lose important data.

What? You flash tar files with Odin not zips, and are you using the PC version?

Did anyone ever find a solution to this problem. I'm having the same issue after doing a soft reset through the settings menu. Through Philz touch recovery wiping dalvik cache does not work and same error messages you receive come up when trying to wipe user data/factory reset through recovery. This is becoming really frustrating because I know there is a fix I just can't find it anywhere. Please help!!!!!!!

You need to debrick image and reflash/fix the corrupt partition on your phone. Go to the following thread. .http://forum.xda-developers.com/gal...a-unbrick-t-mobile-s-iii-qhsusbdload-t2904318 and if you follow exactly, down to the millisecond, as instructed, you will succeed, that is assuming your device is still able initiate into "download." mode and MOST IMPORTANTLY, you have your device specific debrick image. . If and when your device does succumb and is back online, give your utmost thanks to docholiday77.

[Q] OtterX doesn't see SDcard

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.

Bingo! That seemed to fix it. CM11 is seeing the SDcard just fine now. Thank you!

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.

Yup! Didn't seem to fix the issue.
Is there a way to put the Kindle back to 100% factory specs, like SBF for the Droid X or Odin for Galaxy S3?

Is this what you used to re-partition the system, data, and cache partitions?
[HOW TO] Fix "Failure to mount" sdcard, system, data or cache

SM-T210R can't mount /system

Okay so today I tried to flash Inspirekat v2.1 rom on my galaxy tab 3 via latest TWRP, and after I wipe system, data, dalvik cache and cache I reboot into the system and I can't get passed the samsung galaxy tab 3 splash screen after some time I found out that the problem is the unability to mount the /system file, then I tried CWM and still the same thing.
Unfortunately I didn't make a backup because I didn't have any precious data there so I just thought I would skip that, I've also tried formatting all data on internal storage but with no avail...could anyone light up a candle for me?

If you wiped "system" after you flashed, then you no longer have a rom installed. Re-flash the rom.

Sorry I messed it up a bit in my previous post, I didn't wipe system "after" I flash but before I flashed
Every time I try to flash it just takes a minute then I reboot into the system; same thing happens then I get back into recovery to see that the /system is unmounted and can't be mounted back also when I try "repair partition" it shows that only 54mb of /system partition is used and around 1300mb is free, any insight on that?
Some errors about not being able to read storage file context and can't find path to /sdcard also appear sometimes on the log window or however it's called at the top right.

TWRP does have some issues mounting system sometimes.
Once you boot into recovery, choose the reboot recovery option and try the flash sgain.

[noob] How can i change to f2fs inTwrp?

I'm on zenity rr latest build with render kernel eas, I'd like to know how i can change file system to f2fs and what it will erase...And then... Is it worth changing to f2fs? Probably this question has been asked many times, but if i found it i wouldn't have written noob in title

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.
