I want thw cleanest flash possible. I want to format my sd card and everything. Im trying to see if this will help get the junk out of my sdcard and other hidden things that impact battery. Besides the typical CWM wipes what else can i do? I basically want everything gone except CWM to flash a new rom.

First thing, format /sdcard, then place the ROM you want to install on there. Now do a NANDROID backup in CWM.
Once this is done, go ahead and:
Data/factory reset
Format /system
Format /boot
Install new ROM
Now you can start fresh
why doing "nandroid backup" ?
and
is there a risk of loosing IMEI ?
Thanks
Nandroid in case you want to take your phone back to a known working configuration or if something goes wrong and you don't know how to fix it. Or just general backup purposes. Just do it.
Always a risk of losing imei somehow. Make a backup of your /efs folder and store it safely in case of emergency. Following the instructions won't touch that folder, though.

How do i connect via usb through CWM ? To copy over my rom after formatting everything?
Sent from my Nexus S using xda premium
Go into mounts & storage and hit "mount usb storage". Just note, as soon as you leave that screen in recovery it will be unmounted.
I recently managed to successfully root my TF101.
I installed CWM (Via ROM Manager) and downloaded CM9
I boot into CWM and attempt to do a nandroid...can't find path.
I attempt to just install from SDCard...can't find path
Realization (and research) hits that CWM can't see the external sd, and the system doesn't see it as SDCARD but EXT-.
CWM can't see the internal SDCard because apparently on the Tablet the ICS encryption locks that down (but doesn't on my EVO since the SC Card isn't part of the internal storage)
I attempt to perform a factory data wipe to clear out the encrtyption , but upon reboot CWM loads. I try to perform the boot-launcher data wipe, but then CWM loads.
I try to use CWM to factory reset but since it can see the damned SDCard because of the encryption, no dice.
My machine is not bricked, as I can still boot into the previous install but I can't seem unable to format the thing to install CM9.
What to do, and thanks.
It has been said multiple times before DO NOT USE ROM MANAGER.
Either use Thing O Doom's peri to install a different CWM or Gnufabio's Recovery installer or NVFlash a rom to completely wipe. And don't use encryption there is no point 99% of the time
I didn't check here first, which is obviously what was my first mistake.
Will any of those recoveries be able to access and format the SD Card area?
Also, I use encryption as I do have sensitive things on my machine that I don't want exposed in case the machine is stolen. First time I've ever had it give me a problem, as the phone encrypts differently.
Team roug's recovery has internal and external sd support and i think the encryption is an ics/tegra 2 bug more than anything
Ok, so I managed to get the new recovery on via Thing O Doom's peri. And I was able to install Revolver via the ext card...but upon boot I was prompted for my encryption pin and got the message that android was updating...My Build number is now Revolver but everything is the same as it was. I still can't factory wipe this damned thing.
Upon request to wipe, it boots back to recovery and says formatting data and cache, data wipe failed.
Tis site states http ://0xfeedface.org/blog/lattera/2012-06-04/installing-cm9-encrypted- android-tablet
The dilemma
When you encrypt your Android device, the /data partition is what gets encrypted. The partition in full is encrypted and cannot be mounted within CWM. CWM also cannot perform a wipe, since it cannot mount the /data partition. And CWM cannot mount the external SD card. This is our dilemma. No access to the internal SD. No access to the external SD. No way to perform a wipe and format the internal SD from CWM.
The Solution
What we need to do, then, is use adb while the tablet is in recovery mode to reformat the internal SD card, thereby removing the encryption. On the US Transformer Prime, the internal SD card is at /dev/block/mmcblk0p8. The partition for our spare SD card will be at /dev/block/mmcblk1p1. You will need to replace those device entries for any other device you might attempt this on. After formatting the internal SD card, we will mount it and then mount the external SD card at /data/media:
In CWM, wipe cache
adb shell
mke2fs -t ext4 /dev/block/mmcblk0p8 # Warning: This can take a while. Be patient.
mount /data
mount /dev/block/mmcblk1p1 /data/media
Now go back to CWM on your device, then go ahead and flash your CM9 and gapps zips like normal. You now have CM9 installed! The /data partition is not encrypted. If you do not need to flash any other ROMs (unlikely if you're reading this article), feel free to re-encrypt your device.

I don't know the block numbers for the TF01
you need to undo the encryption before you can wipe anything
You can't. Hence my problem. I cannot mount,delete, or format the SDCard. It sounds like the process in the above post is the solution, but I don't know how to find out what block numbers the tf101 uses.
If you don't mine losing your data NVflashing a rom will resolve all the problems
Yep nvflash will do the trick otherwise as the solution you found yourself explains
Use adb in recovery ( in other words hook it up on a pc ) for this you will need android sdk runnin on your pc
More info about adb u can find here

Good luck
Thanks to all, I have resolved my issue!
I had to download the stock rom, extract the blob, and use Wheelie for PC to NVFlash everthing abck to stock. I was then able to update over OTA, and use the excellent Thing O Doom's peri to re-root and flash the working recovery.
There should be several items in the Root FAQ up top, such as:
If you are encrypted and going to root, factory reset to get rid of the encryption FIRST since the encryption locks down the SDCARD partition (Unlike on the phone)and none of the recoveries can access it to mount. DON"T use ROM manage on the TF101 and always, always check XDA first.

That FAQ is sadly pretty outdated, I wish I could liberate the OP
Glad all is working now though.
Im having a trouble reflashing a ROM. During my efforts to fix my horrible battery life problem by doing Odin back to stock and reflashing DK ROM something else has gone wrong.
I go to to Recovery and I tried to wipe data and Reset to Factory
it says
Formatting / data......
Formatting / Cache....
Formatting / sd-ext....
E:format_Volume: make_extf4fs failed on on dev/block/mmcblk1p2
Formatting/sdcard/.android_secure....
Data wipe Complete.
It also says, sd-ext.img not found when I restored my Nandroid backup. Not sure whats going on here...
When it restarts, its still the same old rom with everything still there, just with user data wiped like my google login. How do I fix this? I have already Odin back to stock, rerooted and CWM and am still getting this issue. Could this be contributing to my terrible battery drain?
Nothing wrong, that's normal.
ROMs on phones that didn't have enough local space to install any real number of apps, etc (think Nexus One, or HTC Evo 4G) used to create a second partition on the SD card. This partition was formatted to ext4 and mounted in place of stuff like /system/apps or /data, etc..
Nandroid simply tries to format the partition if it's there, and obviously it isn't. I doubt anyone here has that partition. The sd-ext.img would be the image file nandroid would create if you did have the partition and you backed it up.
But the problem is I cant flash another ROM without doing the factory reset, and when I do factory reset I get that error and the new ROM isnt flashed.... I have never had this error before when I flashed DK originally, or on my last Blaze phone. I need to fix this issue so I can flash a different ROM, or next newest update to this ROM.
You've got some other problems then, because I get that error all the time and have for some time on all sorts of phones.
Once the /data partition is formatted, your wipe is complete. The /cache is good stuff too... once you see those two lines, you are all resetted.
If you nandroid restore, you're going back to what you had.
So why wont it factory reset then? Everytime I do factory reset in recovery, it shows all my files and stuff still on the phone. It never completely wipes my phone. I dont know what to do or what the problem is...
Is there a certain way everything is supposed to look in mounts and storage? Whats supposed to be mounted or unmounted? And what should be formatted?
Factory reset doesn't wipe your sd card. For that you have to format it from the settings menu.

Can you explain how to do that?
I beilive he means in CWM, under mounts and storage, format /sdcard
Sent from my SGH-T769
No, I meant in android. I'm sure a quick Google search would turn it up, but here goes: Settings -> Storage... you'll want to unmount first, then format.
SD card = removable card
USB Storage = internal storage
Just remember, this will destroy ALL your data on whichever you choose to format. Everything, your pictures, music, etc...
I'll try to explain myself before people jump at me. I saw another thread with same question but seems like people misunderstood the question.
I am not talking about "lack" of memory, or not having another 32/64gb availble, etc.
I'll give you an example to what I am referring to:
Recently I decided that my rooted S2 needs a little 'refreshing', meaning - not just a wipe, but a complete format, to start from scratch. So I formatted everything, including /system and /emmc partitions. I then re-booted to recovery and had my rom file on the SD card so i was able to get a clean install.
Now, the question is - say I am at a stage when I need to 'refresh' the phone and wipe everything out. How do I then access the rom file for new install if I don't have external SD Card?
Thanks.
with adb.
What I do when I want a clean start, is I will load the rom/gapps/kernel to my phone, go to recovery, factory reset (with system if you choose), then flash all the things you want, then go back and wipe internal storage after. Then you're left with a fresh version of the ROM you want to install and no files whatsoever in the memory. Hope that helps.
I had the same suspicions a while ago. Basically with the nexus 5, even without an external sd, you can still do a full wipe of everything other than your storage. There is a path on the internal storage which essentially acts like an sd card, and when doing wipes in recovery it will not be wiped, unless of course you specifically choose to format /sdcard or all of /data. Read here for more info. I found that explanation very helpful.
So to answer your question, no, its not an issue.

I have the same issue, with my OCD, that I always need a complete wipe of EVERYTHING.
One option, I recommend if that's not an option at the time of flash, is to simply "reset" in settings. It clears out the whole SD, which is something I usually want to do when I want a FULL flash

Reset in settings just uses recovery unless something changed I haven't realised?
It should be down to what recovery you have (stock vs custom) as to whether a reset (regardless of how you initiate it) wipes /sdcard or not... or are you saying that's changed now?

Problem with factory reset, as far as I know, is that it does not wipe out everything. When I do factory reset in my S2, I still see old folders (even though empty) from before the wipe. That's why I like to format everything clean. When I mean clean, I don't want to see any old folder in there

OK, but if you do that, where do you 'keep' the rom file and how do you flash it?

Android Debug Bridge. It allows you to communicate with your phone via command line tools.
You would keep the rom somewhere on your internal storage (data/media) just like you would on any other phone. Then after wiping, you would simply choose to install zip from sdcard and your rom, along with any other flashable zip on your sdcard will be available to install. Basically when you do a typical full wipe from a custom recovery, the contents of your internal storage/sdcard are not wiped.

Lately, I've noticed that it wipes the Data as well. Unless It was only on CWM that it happened? I had installed CM11 with CWM and wanted to reset my SD. I used the reset feature and it erased everything, except the OS

I would flash the Rom first, then do the factory reset, the only downside is the nandroid you made may be lost, unless you uploaded it to GDrive or something.

3. Rooting
Now that your phone has an unlocked bootloader and a custom recovery installed you have a two options to gain root (Pick one or the other. You don't need to do both)
Option A) Flash SuperSU binaries which will give you root with the stock rom
Confirm that you have downloaded the SuperSU zip from the downloads section above and that it is located in the platform-tools folder inside of the android-sdk-windows folder on your desktop.
Turn the phone off then boot into the bootloader. (volume down + power). Once in the bootloader use the volume rockers to scroll onto Recovery Mode, then press power to select it. This should bring you into your newly installed custom recovery. Leave the phone at the home page of the custom recovery.
Open a command prompt window and run the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
adb push UPDATE-SuperSU-v[COLOR="Red"]X[/COLOR].[COLOR="red"]XX[/COLOR].zip /sdcard/
This will copy the SuperSU zip onto your phone. Once the command has completed continue.
Instructions for TeamWin Recovery Project (TWRP):
Install > browse to SuperSU zip and select the it
Swipe to confirm the installation. Then reboot.
Click to expand...
Click to collapse
It shows how to "Push" a file to your phone. That is the best way, IMO. But instead of SuperSU, just "adb push ROM.zip /sdcard/"

Flashing the rom? Its honestly not any more complicated than flashing a rom for any other device. You download the rom to your internal storage. Boot into recovery. Then do a full wipe:
TWRP Full Wipe:
- Wipe
- Advanced wipe
- Select all, except internal storage
- Swipe to wipe
CWM Full Wipe:
- wipe data/factory reset
- wipe cache partition
- advanced > wipe dalvik cache
- mounts and storage > format /system
Finally you can then flash the rom (and gapps).

It's not really and if you're rooting and flashing any device, adb is essential knowledge.
Once you've installed adb (millions of guides on the net) you just boot into recovery then connect to pc via usb.
adb commands are run from cmd prompt.
For example...
adb push c:\users\sbi1\desktop\rom.zip /sdcard
Would push the file on your windows desktop called rom.zip to your sdcard.
You can even sideload from recovery.
Or better yet,.just don't wipe /sdcard. It has no benefit other than looking tidy anyway

I searched for an answer and noticed it's a common issue. I am trying to flash a kernel on to my already flashed rom. I was wondering if there is a more current fix. More importantly, how can this be avoided in the future. Thank you guys!
Its caused by a bug/error with either the filesystem or encryption.
Did you wipe data after flashing the new ROM? Data from stock usually doesn't work with custom ROMs.
Do you have a PIN/password on Android?
Are you using the latest build of TWRP?
Press the menu button at the bottom of the screen in TWRP and post what the error message is in the red text.
It's caused by no root access

Something is probably wrong with the data partition. TWRP should always have root access.
Try in TWRP:
Wipe > Format Data > Slide to format
This will erase the data partition, so backup everything to a PC in Android first if needed. It should allow TWRP to mount /data again.

I've debated on doing this. I'm not worried about losing pictures texts etc as they're backed up.
I read that it essentially leaves the device with no OS. If that's wrong please let me know!
I have found that if I choose Slot A and reboot system it reboots me in to TWRP. If I choose Slot B it runs the OS like normal (except I still have issues using Facebook and it's services).
The ROM works and I can perform all the custom mods on it. I just want to flash a kernel and the problem persists. 0 mb in storage.
It's trial and error at this point. Fail fast fail forward. I have another phone I can use but I love the OnePlus. Any help will be appreciated!

I'm not willing to risk it until I know how to get the custom ROM on to the storage to flash it.
Yes formating by typing in yes will wipe it all,everything including pictures, with no rom on it at all. If u choose to do that, don't close twrp. Instead you should be able mount after wards, once mounted transfer the magisk zip, twrp, and your custom rom(has to be 1.5gb not 200mb through magisk). Flash magesik, install ram disk twrp, install rom. That was a method I've done before but if u want to keep everything there is other way
fastboot boot twrp.img, that command boots twrp if u have it or don't, installing to ram disk makes it permant...this boot command is just a one time thing each time. It's what I do when new firmware update, I loose root but I regain it each time
Never heard of formating data removing the OS, that would be if you wipe the system and normal wipe is like a factory data reset and therefore will not wipe your phone of the OS

I attempted to format. It said
"failed to mount /data (device or resource busy)
"unable to mount storage"
Try this in recovery, sometimes its known to work.
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to EXT2.
Repeat the same process selecting Ext4
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to back to EXT4.
Try formatting data after this.

Since you dont care about the data on the phone I would just do 1 of 2 things. 1st I would reflash twrp on to you phone if that doesn't work then I would just grab the fastboot ROM and just flash your phone back to full stock reroot and install twrp from scratch. I would not try to start repairing partitions. I wouldn't want to worry about screwing up the EFS partition
Well in an update, I formatted the
Storage and now I'm stuck in bootloader screen. It's unlocked but I'm having a hard time flashing a ROM through adb.
I use the twrp version 3.3.1-2
Best would be to just use fast command to boot it
But it should be under wipe/format data/then type in yes
That was what I was trying to have you avoid. If your can boot to fastboot download the fastboot ROM I told you to and run the flash-all.bat file. If your on 9.5.8 make sure you use the fastboot ROM of the same version. Do not flash azip of a different version firmware like 9.5.7.
It happens to me any time I'm in twrp and flash a rom then reflash twrp. It doesn't matter if I flash Magisk or not the issue always happens. What I do is use a USB C flash drive and plug it in when I want to flash/backup a rom. This way I can always access it. After flashing any rom then booting I'm always able to access my internal storage again. It seems like a bug in twrp.
The strange part is when this bug happens your files are encrypted in a 0 folder but you can still copy from your PC to your internal storage while in twrp.
I essentially soft bricked my device. Called OnePlus and they got me up and running. That's awesome that they have that service!
Are you removing all security? Pattern, pin and fingerprints? Are you decrypted? Never had an issue with flashing a ROM causing these issues which is why I'm asking. Something you've done at some point is causing this
I'm not sure what that was. Ironically enough I am now stuck in TWRP boot loop. Hopefully I can figure this out otherwise I have to call oneplus again.
I will admit I may not know everything but it's trial and error. I don't have anyone to really teach me this so I try to read the forums and learn. You guys have been great!
