double check your partitions, make sure you have FAT32 + EXT3 @512mb then flash the chosen rom again, this is your best chance.
go with my rom, linked through my signature, the update will wipe the Cache + dalvik cache but keep all of you personal data and apps.

How do i check the partitions? Cant boot so can`t see them that way and haven't got card reader or anything. Im sure its got something to do with partition. Does this seem like it is causing the problem?
Any help appreciated.
bump, need help
have you wiped everything before flash?
I wiped with rom manager after downloading rom. Not sure of all the custom recovery options as rom manager usually does it all for you. Not sure if i should wipe date, cache etc, will this wipe my backups? Tried removing sd card but wont boot, not even sure how I would get another custom rom on sd card so i could flash that. I have both defrost 2.4a and opendesire aswell as a nandroid backup on my sd card but can't get these to boot either
Must be something to do with the sd card partition. Everything I try I get the message
E:Can`t mount/dev/block/mmcblk0p2(file exists)
error mounting sd/ext/!
Don't know what this means but think its causing the problem.
perhaps a bad sector on the SD?
try backing up everything on the SD, format it again & try the roms one by one to see which possible causes the issue
U need to try an alternative recovery.
Try using unrevoked, and flash and different recovery.
Sounds like the fake flash recovery u got with rom manager Isn't clearing ur partitions.

in Windows XP Disk Management, right-click the existing partition,
and click delete, that will leave the whole card as unallocated space. Then
right-click on the unallocated space, and click new partition.
edit : or install http://www.sdcard.org/consumers/formatter/sdfv2000.zip
free SD partitioner
in disk management it only shows the size as 3.18gb, I made the partition through rom manager which I think formats it in linux which windows doesn't recognise.
Taking the Sd card out gets in onto the animation screen, so a little further, but still doesn't boot. Very frustrating. \\\\\any more help appreciated.
Flash a ROM that doesn't use Apps2SD.
can you link one for me pal, ripping my hair out here, lol. By the way how do you do full wipe in custom recovery ie data, cache, is that it?
edit. Don't matter. Sorted. Copied an earlier backup of sd card onto spare sd card and did a recovery. Still need to know how to remove the partition from other sd card using windows.
This was definitely the problem and won't be using rom manager to do another partition.
If someone does know how to remove partitions using rom manager from sd card via windows then would appreciate it if you would let me know...

Full wipe can be done using the "wipe data/factory reset" option in ClockworkMod Recovery.
To get rid of the ext Partition get gparted or something like that. Normal Windows cant see ext partitions because its a Linux filesystem. You can also take a Linux live cd.
Can't you just take ROM Manager and partition your SD card again? Swap 0/Ext 0/FAT 32 All
It looks like something isnt ok with the partitions so i would recommend to delete all partitions and make them new i also had a problem once with my sd card but after deleting all partitions and repartition it everything was ok again.
I have a Galaxy Nexus that won't boot. It goes through a boot loop. I've tried everything to try and get it working. I've wiped data/factory reset, I've formatted system and re-flashed ROMs that were already on my phone, I've tried restoring backups from several nandroid backups. It never gets past the initial Google splash screen with the unlock symbol.
I'm going to send it in for service, but I'm wondering if there's a way to try to access the flash memory to copy all the data to my computer? I've stupidly done tons of regular backups (Titanium, SMS, nandroid) to my flash memory on my phone, but never backed it up to my PC. I can see the directory structure through CWM 5.5.0.2, but I can't mount it as a USB storage device from CWM and I assume I actually have to be booted up to use ADB.
Any suggestions?

You should be able to do adb with the device in recovery mode. I'd recommend doing something like
Code:
> adb pull /data/media sdcard
This will copy the entire contents of the pretend SDcard on the phone (/data/media) onto a new folder on your computer called "sdcard".
I don't think there's a way to access the internal memory through CWM. For CWM to do that, is that to unmount that partition, and it cannot unmount data (where the sd-cad resides) as android wouldn't run without the /data partition, or so I've heard.
Feel free to correct me if I'm wrong.

Recovery is not Android, it will run fine without the /data partition mounted (though there isn't a whole lot it would be able to do then, since that's where all your flashable goodies would reside). CWM accesses internal storage all day long when you're flashing ROMs and kernels and whatnot.
Thanks! I assumed ADB wouldn't work in recovery because I tried it quickly on a PC that didn't have the drivers installed. I plugged in it on my upstairs PC and I'm doing a very lengthy adb pull as I type this. Thanks!
I've been working on this port for personal use, but I figured others may find this useful.
What is it?
It's a script flashed through recovery, same as when you flash a ROM, that wipes for you in one simple step!
What does it do? (Wipe)
Depending on which version you choose, it calls on mke2fs and e2fsk to format /cache /data /system, then check the partition afterwards.
It will wipe /cache for the cache only, or system, cache and data for the full wipe. It does not do the external SD card, but it WILL FORMAT INTERNAL SD!
What does it do?(Nullify)
Same as the wipe, however this first calls on DD to zero out the partition, leaving NO DATA behind. Its a full overwrite of all data in the partition, with no way to salvage after running. The chances of anyone being able to recover any data after this is run is pretty slim outside of extreme power users and like..the CIA or something. Even then the data would be so corrupted I doubt anything usable could be rebuilt. Best used when bugs come up regardless of wiping multiple times, or prepping the tab for sale, no personal data can be retrieved from the internal SD.
How do I use it?
This is assuming you run a custom recovery!
System Wipe:
Reboot into recovery (this has been tested on my personal device with CWM and TWRP).
Make a full backup.
Install from SD, pick the system wipe zip.
Install the zip.
Wait a bit, it should take a minute for full wipe.
You can either restore a backup or flash a new ROM zip.
OPTIONAL: Fix permissions
Reboot system
NOTE even on a restore first boot will take longer then normal.
Cache Wipe:
Reboot into recovery.
Make a full backup, just in case.
Install from SD, pick Cache Wipe zip.
It'll take a second.
OPTIONAL: Fix permissions
Reboot system
NOTE boot will take a little longer then normal.
Nullifier:
Make sure you have at LEAST 50% battery or are plugged in.
Copy all information and files you want to save from Internal SD to PC or external SD card (the slot one).
Reboot into recovery.
Make a nandroid backup.
Install zip from SD, pick the nullifier zip you want to run.
Cache nullify takes about 9 minutes, full system takes about 35-40.
Check if you can mount /system /data and /cache, if you can, proceed, if not, reboot recovery (recovery not system!)
Install from zip, pick your ROM zip, or restore a nandroid.
Reboot system, and do whatever the DEV suggests.
NOTE Boot will take longer then usual.
What's this ported from?
This is based on work by Volk's Nullifier script for the G2x, and based directly on the Hellfire Nullifier. It's no longer really even close, but the concept and work is still based on their work.
What does each version do?
Cache Wipe: Formats /cache and deletes /data/dalvik-cache.
System Wipe: Formats /cache /system and /data. Recovery mounts INTERNAL SD to /data/media, so THIS DELETES INTERNAL SD!
Please backup your INTERNAL SD before running this or you will lose everything on it!
Cache Nullify: Nullifies /cache and deletes Dalvik-cache.
System Nullify: Nullifies /cache /data /system. THIS DELETES INTERNAL SD!
Cache Wipe\Nullify is meant for cleaning up when things get buggy.
System Wipe is meant to format everything for a new rom install or nandroid backup restore. The recovery will remove directories around /media, not format, this will format /data completely in preparation for new data.
System Nullify is meant to destroy all data in /system /cache /data, including your internal SD, by zeroing out the partitions. In other words, writes 0s from start to end.
Who should we thank?
Volk, who created the initial concept and script Nullifier, which this is based roughly on.
x0hell0x who ported it to the Hellfire Kindle Series, which this is based directly on.
da-pharoah, who helped me through the process and dealing with different device IDs in different recoveries. If it weren't for him I'd have given up and made seperate zips for each recovery.
What's coming up?
Right now I think this is complete! I'm unsure of how it handles CWM, so I may need to create CWM versions.
Things to note! READ THIS!
This is intended to run on the Acer Iconia Tab A100 ONLY! I have not set this up to run on any other device, and doing so may result in a brick! This wipes partitions, and could wipe boot, recovery, or any number of other partitions if run on a different device!
This was created and tested on my personal device using TWRP recovery! Using any other recovery may or may not prevent the script from running correctly! System wipe\nullify erases internal SD please backup data and ensure your ROMs and Nandroids are stored on EXTERNAL SD CARD!
The wipes are meant for every flash, the nullifiers are NOT meant for every flash! They are meant for changes from one ROM to another rom, or every few flashes, say 10. Otherwise use manual wipes or my wipe scripts!
Porting:
I'll consider porting to other devices if I have time, please PM me if interested.
I am not responsible for any damage that may occur from use of this script! If you choose to use this, that is your choice. As with anything else, flashing can cause problems including data loss, hair loss, bricking, brick laying, and magical fairies cracking your screen.
Changelog:
5.25.12 v0.1
Initial attempt at porting over, full of fail.
5.26.12 V1.0
Wipe Cache only version completed and successfully run on my device in CWM and TWRP.
5.27.12 V1.0a
Minor changes to the script for cache only version.
5.28.12 V1.1
More changes, changed handling of device ID from recovery to handle both types of recovery reporting (thanks da-pharoah)
Adjusted the status bar indicator to better reflect where in the operation the script is (thanks da-pharoah)
5.30.12 V1.1a
Created post, minor clean up of spelling errors.
5.30.12 V1.3
System Wipe finished after some major changes to command arguments. Cache wipe getting updated as well to 1.3 with a fix to rm argument.
6.1.12 V1.4
Cleaned up an error with the cache being formatted and throwing errors. Updated and cleaned up Cache Nullifier, all scripts updated to 1.4.
6.1.12 V1.5a
I made a mistake and updated the wrong script versions, resulting in nothing being formatted due to the system not unmounting before carrying on with the script. My apologies, I hadn't noticed the issue until I attempted to use it today for a rom install. For now, use only 1.5a versions, updating them all now with the fix. Slight changes to output to help see what it's saying. Working on getting the status bar timing correct.
6.3.12 V1.5a Final
Rechecked each script, and should ALL now be FULLY working in TWRP. CWM may or may not handle the script correctly, if you run into issues like it not working, send me a PM or Email with /cache/recovery/last_log and if there dmesg. System Nullifier added finally!
Please bear with me, I'm finishing my High School course and only have limited time on any given day, and it mostly goes to schoolwork, I will update when I can, and I really hope to have the full wipe completed within a few days. Nullifier may take longer as I'm not sure why DD hangs.
Downloads: These are on my drop box for now, it's small so it shouldn't cause issues.

does this actually "wipe" data so that is can not be recovered? or just erase it?

Right now all it does is format, or wipe, with mke2fs to whatever FS that partition uses, EXT4 or EXT3. Its not much different from using CWM wipe/format commands, just does it all for you. Once I figure out why DD hangs, it will then Nullify the partitions, complete and utter destruction of data by overwriting the partitions with 0s, leaving no traces behind at all. I'm currently hammering out the full system wipe script, which will do /cache /system /data and /data/dalvik-cache, the /cache/dalvik is done when /cache is formatted. The problem I ran into is for some strange reason, internal SD is mounted to /data/media in recovery, meaning formatting /data directly will erase the internal SD card as well. The recovery gets around this by deleting directories around it, but never formats it, which IMO can lead to issues and bugs down the line. I have only 1 method of dealing with this, and that's moving /data/media to the external SD card (SDC), formatting (or nullifying) then moving it back. As this can mean moving up to 8 GB, its not a liable method as it will take a LONG time to move it there and back.
I'm hoping to have the first full system wipe available tonight, however it WILL erase the internal SD, this is only to be used if you don't care what's there, or are having alot of bugs, and copy your stuff off before running. I can't test it since the wife is using the tab now, and I'm not gonna put it online without testing it first.
TL;DNR: It just erases it.
Updates
1.4 versions are up.
Now includes Cache only Nullifier! This is the wiping that I think joeyjojojjjjjj was looking for. Unrecoverable data destruction. Currently DDs /cache, then formats and checks, then deletes dalvik-cache. Overwrites the partition with 0s from beginning to end, leaving nothing but ZERO behind, hence blackhole nullifier.
Hoping to finish up System Nullifier tonight some time.
1.5a Final is done
Scripts are now up to 1.5a Final. The zips are still labeled as 1.5a but they are all updated. Added system nullifier! Please use caution with the wipes and nullifiers, and ensure internal SD is backed up and your nandroids and roms are stored on external SD card before using!
Tested working on TWRP Recovery, YMMV on CWM recoveries.

Wipes with Crossix Memory Swap?
I am using the Crossix memory swap.
If I use the system wipe script, will it erase the data on my *actual* internal sd (i.e the 5gb partition that I largely don't use). Or will it erase the data on my *tricked* internal (my 32gb microsd card)?
Thanks, I can't wait to try this stuff out!

Internal SD only. It will never touch your external SD card. And the reason is....
The crossix mount swap is only active when android runs from /system. This is run from recovery, so any system mods don't affect anything running in recovery.
So you're safe, only the included internal SD is wiped, regardless of crossix's mount swap.

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.

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.

Sorry to bump old thread. I just deleted system, data, cache etc everything. Now when i attempt to
Reboot it warns that no OS installed. I m using TWRP. is it safe to power off the device? Will i be able to get back to recovery to flash a new rom afterwards, as i dont have one ready now??
Btw i hav nexus 7 , but didnt find this discussion there so i am posting here.
Thanks in advance for help....
I accidentally formatted system on my HTC desire HD. but i'm unable to install rom in it. If anyone can help me make it working(instruct how to install ROM in it) i'd be grateful.

I own a Galaxy Tab PRO 10.1" Wifi (SM-T520).
I have the stock ROM, rooted and with TWRP. And SDfix...
I have tried fat32 and ext4 on MicroSD, and without MicroSD. No difference.
I cannot boot any custom rom (Stuck at Samsung logo). Sometimes when I try to install a rom, it fails, or reboots TWRP.
I also encountered problem when trying to restore a nandroid. No DATA partition can be written to, restore fails. (after reboot recovery, its no problem to restore)
Angry Birds Epic does not work. It stops at "Loading Levels", and sometimes it fails to start, and says its not installed.
Spotify says that that it cannot be used because it has no storage.
I can access the partitions, but they are not writable. A reboot is getting the internal/external SD to be writabe again.
So, what is the problem with the partitions on TabPRO? or is it the Samsung android rom thats the problem?
Can it be fixed?

Try installing FolderMount from the PlayStore. It can detect and fix issues with your partitions. You just need to run it, then reboot. I seem to get issues writing to my data partition after I install TWRP, on my SM-P900. FolderMount fixed it quickly and easily.

FolderMount did find an error, and fixed it, but same result
And it "fixed" the same problem as the SDfix app did.
But, I still made some progress. I managed to install a custom rom without error, and fully booted.
Team Freeze Rom installed fine. The rom is just under 800Mb. So i thought maybe it was some faulty memory sector on my tab.
Then I tried to flash GigaWatts ROM, and it failed. Same with ProPlus Rom.
When restoring my last nandroid, it fails when writing DATA partition.
Then I tried to restore my first nandroid, from "stock" rom, and it restored just fine.
First nandroid was from internal SD, and latest was from external SD. Made me wondering, so switched yet again another MicroSD, took a nandroid to it, and tried to restore. It fails again at DATA.
Then I tried t install GigaWatts ROM from internal SD, instead of external. Works without error.
Sooo.... I can flash custom ROM`s from Internal Memory, and restore from Internal Memory
Not from external SD.
Still, I do get internal/external SD dropouts, and getting "no space left/no memory to install on", which can be "fixed" by a reboot.(Still, it should`t be like this, and are quite annoying.
But, still no luck on getting past the "Loading Levels" on AngryBirds Epic
Where is the root of the problems? Faulty device? Android ROM? TWRP making trouble?
Please guide me if any logs should be provided to find out where the problems is, if i`m not the only one with these problems.

You can try flashing a stock ROM via Odin, and start from scratch. Factory Reset, Reroot, install twrp, etc. If you still can't write to /data properly, you may need to find a .PIT file and repartition your internal memory using Odin.

I have had to reflash stock with Odin 4 times by now, and it has been the same pain every time.
I was hoping not to use re-partition, so I will wait and see if some new info will come by from other users, as I see there are more of the users that struggles with flashing custom rom. (Stuck at samsung logo, installation fails)
So, will hold off for a few days, and if no new info about partitions, rom flashing, low memory, sd cards not mounting correctly, etc, then I will try re-partition...
meanwile, I`ll investigate som more on my own, read overall the internet
Ok, so i have tried and failed, and learned something on the way
Ext SD is useless for flashing rom, nandroid, etc within TWRP. It does not mount partitions correctly.
If I make sure DATA partition is mounted in recovery, and only use Internal SD, everythin flashes, backups and restores just fine
(Mabye an issure with TWRP?)
SDfix, or FolderMount fixes write permissions to Ext SD in rom to use TitaniumBackup, games, downloads, etc.
Hopes this can help others in simular problems.
And thanks to all that have helped on the way
