I've been stuck in a weird place for some time with my phone. After I installed clockwork mod, backed up, installed some flavour of FroYo, and made the mistake of trying to flash back my old back up without properly wiping things have been getting weird. I can use ODIN to flash fresh ROMs, but I always get a bunch of FCs at startup, and most apps don't work. I tried to do all kinds of tricks to completely wipe the internal SD, but there is always some remnants of old fun hanging about causing cascading errors and FCs. No matter what I try to do, MyBackupPro and Rommanager is always present, but not working.
How I can completely rid myself of anything not stock ROM?
I've finally gotten back to root ADB, after a long and hard battle. I believe this may hold the key to salvation for my Vibrant.
Any and all suggestions are much appreciated!
Things I've already tried:
EUGENE373_SamsungS_Froyo_PDA -> Stock 2.1 T959UVJFD
EUGENE373_SamsungS_Froyo_PDA -> battery pull -> Stock 2.1 T959UVJFD
Stock 2.1 T959UVJFD -> EUGENE373_SamsungS_Froyo_PDA
Bionix1.9.zip - would not install due to some error I can't recall right now. Will update.
Factory wipe - from Settings menu
Wipe in Clockworkmod menu
Wipe all in adb shell
The weird *2767*3855#* factory wipe
UPDATE:
Strangest thing happened: I flashed an old ROM back onto the phone with Odin 1.52, then the Updated Stock 2.1 also via Odin the usual FC-ing was still there. Then I rebooted into recovery, reinstalled the Clockworkmod recovery menu, installed the root-update.zip in order to have root shell access. Then I pushed VibrantDeodexed1_2.zip and Vibrantfroyo_R3.zip on to the sd card. I tried to apply the VibrantDeodexed1_2.zip, but it aborted due to some catalog not present. However, I did notice that the installation erased /system and deleted some files, and I had the notion to try and install the VibrantFroyo_R3.zip. The installation succeeded, and Lo and Behold!
the phone has returned to the land of the living! Wohoo!!
I do not fully understand how this can be, but there is no Force Closing of programs any longer. What a relief!
Thanks to everybody who contributed ideas!
If you're having problems, back up whatever data you want to keep to your computer. Go download eugenes 2.2 that doesn't brick. Flash that, do a battery pull once it's done (don't reboot). Then go get a stock eclair file, flash that with odin and check repartition. This solved every problem I had from flashing way too many roms.
Yea, when in doubt I thank the deities for Eugene and flash his "Froyo that doesn't brick" followed by the stock JFD firmware.

Yeah, that's the weird part.. It doesn't really delete anything. Files are still there, and so are the un-wanted system files, too.
Does anyone know if I can manually partition the sdcard?
Had a similar issue, and couldn't fully erase my files. Figured out how to completely erase everything, before you proceed, backup your files and be ready to Odin. In rom manager, enable advanced mode in settings, then use the flash alternate recovery option. That set my current cwm version to 2.5.1.2, now when I reboot to cwm i have a menu that says something similar to "sd and storage" and within that menu are options to completely format all of the internal storage. Be careful in there, you can delete everything, incl the sd ext, but I think this is what you are looking for.
Edited - I rebooted and checked the menus, mounts and storage in cwm is what you are looking for after flashing the alternate recovery, I can confirm this removes remnants that an Odin repartition or factory format still leaves behind, let me reiterate, backup your personal files, cause this does remove everything
After formatting, Odin away

When I boot into recovery, I always have to reinstall packages to get to the CWM recovery menu. I tried to clear everything from the mounts and storage submenu; I cleared system, cache and data, then flashed stock eclair. STILL the same applications and files sit on the internal SD.
When performing the wiping, all looks normal. It does take a little time, and the system reports that all is going according to plan, yet no files are deleted.
What can possibly make the phone act this way? Are there no super secret samsung-technician codes that allow me to completely wipe clean the face of the sdcard?
When you get into the storage and mounts menu, I would format everything given what you're experiencing. Format boot, data, system, cache, and sdcard. Dont format the sd ext, thats the physical card. After formatting all of those your phone should be an odin ready blank slate, mine was. Hope this helps.

I was hoping that would help you friend, that process wiped mine clean of all remnants. Good luck in getting her back into a functional state.
After reading som more, contacting Samsung Service, I've decided to send the phone in for service. [sigh]
I've learnt a lot about ADB, pushing and pulling files, rooting, unrooting, swapping ROMS and whatnot. Still, the phone is stuck in that weird place where I cannot delete files.
Hopefully the service team can fix this poor, misguided phone

Hey guys I have been trolling this forum for some very useful information, and it has helped me quite a bit, but on this one I am stuck. Every time I try and delete something on this phone (Samsung Vibrant) it just comes back. This was not my phone before, I am just trying to put it back to stock.
I have flashed the phone 3 times using odin, including using the re-partition option.
When I hook the phone up to the pc, and load update.zip into the root folder, and reboot into recovery mode, it says cannot find sd card/update.zip. Even when I go in and manually delete apps if I reboot the phone, they all just come back.
Am I missing something? part of me wants to say its something easy.. but I have searched and searched about this and found nothing. Is there a mod out there that does this? -Thanks
*edit* Oh, and it seems like any time I think I might get close, I get the little android and the triange w/ the exclamation point.
Bueller?
How are you deleting? What are you deleting? Why are you using odin to delete apps? Not enough info to help you.
Hi, I am just trying to totally wipe the phone back to stock, hence odin. I dont care about info being lost. But like I said.. if I go in and manage applications, and remove them manually, I restart the phone and like magic they are all back.. I am quite confused. I hook the phone up to the pc, open the phone and manually delete pics and songs that way.. unplug the phone from the pc, and its like i never did anything.

If you want to wipe the best thing to do is flash Eugene's Froyo that does not brick. That will get rid of EVERYTHING. From there flash JFD. That will give you the clean start you want.

Yeah, that is the problem. I already did that, and the stuff is still there. I did it 3 times. I flashed it with the 512 pit, did a re-partition and the JFD. Then went back and even updated it to the JI6 firmware, and loaded it with the stock kernel.
I'll help you out before you needlessly flash roms over and over and over.
Before you say, "WTF!!!! That doesn't answer my question" please read to the end.
1. As I understand your problem, you want to wide everything from your INTERNAL SD Card.
2. as such, The steps are as follows:
3. Go to settings.
4. Go to "SD Card and phone storage"
5. "Unmount phone storage"
6. "Format phone storage"
This is assuming that you are ALREADY on stock Rom.
If not, flash the stock first, then wipe your internal SD.
Remove your External SD and SIM card. *(Not required), but i'm paranoid, and this always helps me feel better on the off chance that something does happen while i'm wiping the internal SD.

That was first thing I tried to do, sorry I didnt post that in OP. I tried to unmount and format using the in phone software. I have tried a hard reset using the button combinations on the phone. I have also done a factory format using the service code. All to no avail.
Thanks for the input.. believe me, if I could have avoided the time and hassle of reading about odin I would have. Odin was a last resort.
I dont know if this is helpful or not but after I format the internal sd.
Total Space: 13.18 GB
Free Space 12.31 GB
I am really beginning to think that the internal SD is broken/corrupted or something. As I said in the OP when I boot into recovery, it says it cannot find sdcard/update.zip. Furthermore, if I mount the usb as mass storage, and go into the folders and delete pictures/whatnot. Even if I unplug the phone from the computer, its as if I never did anything. The pictures will all still be there as if nothing happened. If I go in and manage apps, and remove them all one by one, then reboot the phone all the apps are there. These are all reasons why I think the internal storage is messed up.
I was/am quite confused. This is why I requested ideas from people smarter than me.. i.e you guys . Thanks for all the input this far, my OP was a little lacking I suppose.
Did you ever get problem resolved?

@jorsh :
I had the same problem with u. Can't delete few old files that stored in the internal SD. Also, I can't use update.zip in the recovery mode. It says "cannot find sdcard/update.zip.
My phone also can't play MP3 file or 3GP file that transfered from other phone / PC.
Anyone can help us ?
How are you deleting the files?
What are you running?
the update.zip, are you guys talking about rooting, or clockwork recovery?
Sorry, thanksgiving was preventing me from following the thread. The problem is still unresolved. I was trying the update.zip in recovery mode, as far as I know there is no clockwork on the phone. I thought the update.zip was just a recovery image that the phone used as a basis for restoring the phone.

I have tried deleting files a few different ways.
Odin, directly via pc with usb mount, and using the software on the phone itself, and tried using factory formats/resets hard and soft.
What do you mean by what am I running?
i just buy a used vibrant. There are some photos & files in the internal memory. I can erase it with file manager, but when I restart the phone, those photos & files appear again.
Same thing with with the gmail account. This gmail account is sign up by previous user. I can't remove this account.
I already try using "factory reset", but it's useless. Those photos & gmail account still in my phone.
I'm running in 2.1 T959UVJI2
about the update.zip, I'm using for rooting. I can't root the phone too. I'm using the file "SGH-959 Root Update.zip" then rename it to "update.zip"
I put this update.zip that the root folder of my internal SD. Bad thing is, this file is gone when I restart my phone (turn off then turn on). So, when I goes to recovery mode, it always said : cannot find sd card/update.zip
anybody can help me ? pleaseeee. So frustated >.<
Yeah that sounds pretty much exactly like my problems.
Perhaps people are having a hard time helping because we cant determine what you are trying to do....
first, yes, there is a clockwork recovery... download rom manager from the market.
there are going to be folders on the internal memory you can not remove because the OS puts them there.
could you please say exactly what you want to do???
I am just trying to delete everything and basically restore the phone back to factory. But it seems like the normal ways of doing that are not working.
Use ODIN to go to stock ji6 or jk2. I have a guide in my signature
Once you reboot mount the internal memory and format it. Settings > sd card and phone storage

ok ok.... I'll try at weekend. I'm out of town in few days. Thx for the info.
please report back, want to make sure all is well
Hi everyone,
My first post so please be gentle!
I'm running rooted stock JI6 with RyanZa OCLF.
Everything has been running fine (for many months!), then yesterday I noticed a red triangle in the notification area of my phone and when I opened the tray it said something like "internal SD card corrupted". I thought it was a bit odd but just power cycled the phone thinking it would clear it. No such luck! I would get past the T-Mobile Vibrant logo screen, then see the flashing 'S' screen for a while, then black screen. Left for 20+mins and nothing changed. If you touch any of the touch keys, the back light comes on (and locally disappears when you touch each button) but that's it!
I rebooted into recovery and tried clearing cache data and rebooting, no luck. I also installed the Android SDK and using ADB from the terminal while at recovery console. The only command that returns anything is "adb devices" and I get
List of devices attached
T95900****** recovery
(not sure if the number masked by *s is individual )
I've tried "adb -d shell", "adb -d shell ls", "adb -d mount /sd-card" nothing... many other adb commands, nothing.
My next steps to recover the phone are to:
1 - clear user data and reboot... and if that doesn't work
2 - use ODIN to reflash stock JI6 and re-synch apps / data from Google (then probably venture into 3rd party ROMs using clockwork / ODIN)
The BIG problem I have though and where I could really use some help, is to find a way to pull my pics / vids off the phone *before* I reflash. Does anybody know if there's a way this can be done? Is there a way to reflash part of the image and keep my pics / vids intact then back them up before a full reflash?
Oh one thing I forgot to mention - during my uneducated 'debug' I tried to boot using a micro-SD card from another phone, and my phone corrupted that SD card too!
Any ideas??
Thanks in advance for any help!
Im not sure abt anyone else but even if I ODIN back to stock (pics & videos are still there) reflash any new rom (pics & videos are still there)
I ve never had anything wiped unless I go in thru my pc and delete items from the phone

+1 on this or you could try android commander.
Thanks a lot guys! Do you know if "clear user data" from recovery console will delete pics / vids? If not, I might try this first.
wont affect it...
OK i tried flashing via ODIN back to JI6 (without repartition). Same thing... then tried flashing back to STOCK via ODIN with repartition and when it comes back up there's some error about failure to wipe data (in red). Downloading Eugene's T-Mo 2.2 now to give that a try... at least ADB is working at recovery console now, but the phone just sits and resets over and over when i reboot normally. Any ideas?
Go to settings sd card & phone storage and un mount the memory you want to wipe and format.
Sd card is the external card & phone storage is the internal card. That will wipe everything.

Am I missing something? I can't get the phone to boot. Settings where?
for the JFD.tar your using the 512.pit file with it right? Now for some reason if I ODIN with the JI6.tar I have to do it with just it..no .pit file, no re-partition. It gives me an error in (2e)recovery if I use a .pit file with it.
Yeah i tried reflashing 'original.tar' (JFD) using ODIN with the 512.pit file and 're-partition' selected. I also tried reflashing JI6 using ODIN with the 512.pit file and 're-partition' unselected. Neither work.
UPDATE - I tried flashing Eugene's unofficial T-Mo 2.2 image using ODIN (with / without re-partition). When recover console comes back up there are a few errors related to memory access issues but when I clear user and cache data and reboot, the phone comes all the way up. On the surface all looks OK but then I notice (via settings / file explorer program etc) that the phone has no internal storage capacity or external SD card capacity! I'm beginning to suspect (one of) the Hummingbird's eMMC/NAND flash controllers. The only puzzling thing is that access to some onboard eMMC/NAND flash is clearly working otherwise it would be impossible to flash / boot into the OS at all. Any ideas? Does Vibrant have a separate on-board eMMC for the OS and then an additional on-board eMMC for 'internal storage' (I don't think so!) Is there some kind of configuration / mounting problem at startup?
Just tried reflashing just the JI6 tar file (in PDA) without the PIT file and it does the same thing. No errors in recovery console but same old black screen as when I started.
One other quick question - where can I find Eugene's Froyo that doesn't brick the phone image? I keep following threads to find it but they all seem to lead nowhere...

If all else fails and you end up flashing anyways, you can always try using Recuva after mounting the sd card to your computer and getting deleted files back.

@joe98200: Yeah I did that last night. Not much on the ext SD card TBH (apart from Avatar), my files were all on the internal flash and there's not much I can do about that if the phone doesn't see it.
@jmcghee1973: Thanks! I'll give this a try and if this fails too, it's going back to the shop! http://forum.xda-developers.com/showpost.php?p=8698655&postcount=150
I was in Clockwork Recovery after backing up my stock system (this is my first time) it gave me the options in green text: Reboot, reinstall update.zip, etc.
I chose reboot and everything loaded up fine and after checking in Rom Manager I have a backup of my system. I just want to know if that was the right choice. or should I have reinstalled update.zip
I guess my question revolves around update.zip.
What is that file? I know I originally used it to gain root access but do I need to reinstall it from clockwork recovery everytime before rebooting? and when should I delete it? and are there any negative consequences for not doing either?
As you can tell I'm a noob....but hey I can't believe I'm rooted and backed up at the moment. I'm gonna stop here before flashing any custonm roms and get this question answered first.
I think you are fine. I would not worry so much, i have deleted the update.zip, but since you booted up into ClockWork Recovery you are most likely fine.
I am booted back up completely and the stock os is running and I'm still rooted. I just want to know what that option inside of clockwork recovery means. What is the reason to reinstall update.zip from clockwork recovery and what is the reason to reboot? And once I'm booted back up and running when/why do I go into my files and delete update.zip?
It's not that I'm worried...I just want to know why I'm doing what I'm doing.
I would keep the file. Less chance of failure.
You are only going to use cwr for this:
Backup/restore system
Wipe cache, factory wipe, etc
Flashing rom's (install from sd card)
Don't worry about the other stuff.
I'm confused by the op, not sure how you made a backup from how it reads.
I think I made the backup by flashing into clockwork recovery from rom manager. It started with the purple text recovery mode and I hit reinstall packets. Then it went into the green text clockwork recovery....I think. I've only done it once.
So in clockwork recovery I choose the backup/restore option and then the backup option. So then the phone I assume began the backup process and displayed many lines of white text. At the very end it said something about not being able to mount my ext sd card (which) had me worried.....but then it brought up the menu again. The top option was reboot, the second was reinstall update.zip and I didn't pay attention to the rest because I was pretty sure I needed one of the first two....I just didn't know which one. I selected reboot and the phone then booted into the stock os and was still rooted. Is the fact that it wasn't able to mount my ext sd card at the end of the backup process an issue? I'm able to find a backup in rom manager. Also, if the backup process works correctly should the phone reboot by itself?
What I'm asking is what am I booting from when I choose "reboot" from clockwork recovery and what does it mean to choose "reinstall (packet?) update.zip"? I thought update.zip was what I needed to root.
This last step wasn't in your tutorial (purple text menu) so maybe something didn't go as it should have.
I'm not sure.
Thanks s15274n for the tutorial btw. Its by far the most helpful concise instructions I've found and is really appreciated.
Sent from my SGH-T959 using XDA App
The update.zip in the root of the internal SD card is clockwork recovery (CR). When you install CR it does not overwrite your phone's recovery. What it does is install that update.zip in the root of the SD card. When you want to use CR, you need to "update packages" which will flash that update.zip which contains the CR package. That will load CR into memory only and still does not overwrite the original recovery on the phone. When you reboot into recovery from ROM Manager, it automatically reboots and applies the update.zip and places you into CR. If you enter recovery manually (via buttons on boot), you will need to "re-install packages" from the stock recovery to get CR.
So if you want to use CR, keep that update.zip in the root of the SD card. If you erase it, you will need to re-install it (using ROM Manager) before you can use CR instead of the stock recovery. I hope that makes sense. If not, here is the explanation straight from Koush on how it works.
http://forum.xda-developers.com/showthread.php?t=734164&highlight=clockwork
^^ You are all good then.
The SD-EXT is not going to backup, because you do not have a partiotion on your external SD card (no need for one, like some other phones require). This is normal from what you described.
You will never use the apply update.zip option in CWR... just dont pay any mind to it.
When you select reboot system now, that is all it is.... you are basically saying "Cool, I did everything I needed to do (backup/flash a rom/wipe, etc)... and now I am ready to reboot my phone... ie, you are basically cutting your phone on.
Positive you did, but you can open rom manager, click on manage backups and you should see a file there that has a format kinda like YYYYMMDDTIME, that is the backup you made... no action needed, just an easy way to verify you made a backup of your system.

Sometimes I need things spelled out for me. Makes complete sense now.

Hi,
I am trying to restore a couple of nandroid backups, but a Device Administrator app gone "quirky" seems to materialize no matter what I do. I did a CWM Wipe, restored the nandroid backup before the app went bad. However that did not work, the app was still misbehaving. So I wiped again, restored a nandroid backup from before I had installed the app. Still the app shows up again. It has in effect locked me out of the device.
Can anyone tell what can I do to get rid of the app?
Are these Device Admin app supposed to persist like this? Or am I doing something wrong?
Do I need to choose a different wipe mode (I chose the normal one, which wipes /data/, /cache etc). I did not try to wipe /cache separately, as the first wipe does that by itself. Neither did I wipe the dalvik cache, as I thought they are not relevant here. I don't see any relevant files in the sdcard either, though how the app reappears in the nandroid restore before it was installed is a mystery.
Should I mount more partitions before wiping, like the data/cache etc.
Since the wipes don't seem to make it go away, I am not even sure flashing a different ROM would get rid of this app either, however I can try that (since I was planning to anyway, before this mishap). If that doesn't work either, I might just have the most unusual case of bricking ever.
The XDA forum does not seem to be much info about device-admin apps and my search-fu is not good enough today to find anything directly relevant about the other stuff.
PS. btw the app actually modifies the lockscreen. So I don't actually see the files it has with the pre-app restore, however the lockscreen still comes up, perhaps because of some remanant of the app or because of a setting it left in there somewhere.
efs?
Just to add more info, I see some files in /efs, which look relevant to the lockscren/ They have file names like this "/efs/cryptoprop_lockscreen".
Would these files store the data this app stored. I fortunately have an EFS backup, should I consider restoring these files.
If someone doesn't know the answer, can they suggest which devs would be good to ask about this.

PS. btw the app actually modifies the lockscreen. So I don't actually see the files it has with the pre-app restore, however the lockscreen still comes up, perhaps because of some remanant of the app or because of a setting it left in there somewhere.

Do a CWM wipe, and turn off the phone when done by selecting "Power Off"
Now enter download mode, and ODIN flash a stock ROM.
Then re-root with CF-Root and install custom ROM if desired.

Thanks for the help pulser_g2. I am still concerned about the files i saw in /efs related to the lockscreen (see my second post). Would the stock ROM overwrite settings/configuration inside /efs (I guess since the IMEI etc are all in there, that might not be the case)?
Got through finally.

OK this worked.
However after I Odin flashed the stock rom and rebooted, I got this
1. First got a different kind of lockscreen.
2. I entered the wrong password five times (after trying the Device Admin alternate password, my Google password, a new 2-step auth password from google) .
3. it said something about wiping sd card. I couldn't catch it (I should probably have videoed this using my point and shoot camera, but this did not strike me then as it was 2am).
4. I was hoping that the stock ROM will boot, cause it stayed on the Samsung logo for too long. (I had already ordered my USB Jig on ebay anyway, but it could have taken time because of my being far off from the seller.). Finally I got the Android Welcome screen and I let out my breath.
In any case, things seem to ok right now. I feel a slight slowness in the rooted stock ROM from my earlier rooted stock ROM, but I am gonna flash a custom ROM later anyway. Thanks a lot for your help pulser.
So I've got a wifi-only Samsung Galaxy Tab 10.1" and I have gone through the rooting guide. The guide includes ClockworkMod (CWM) v4.0.0.4, which for the most part, works just fine. I'm able to flash custom ROMs, make backups, and restore backups.
I'm having a problem mounting USB storage from CWM however. I go to the "Mounts and Storage Menu" and then select "mount USB storage." When I do this, I get a message saying:
E:Unable to open ums lunfile (No such file or directory)
Any ideas what this means, and how to fix it? Is anyone else able to mount USB storage from their CWM recovery image?
Anyone can correct me if I'm mistaken...but I believe the reason we see this error is because the Tab is not like phones and the internal storage works differently, there is no sd card so it has nothing to mount. I believe it works more like a hard drive. (MTP is different although I know nothing about it) so CWM produces this error but it is nothing to worry about.
More knowledgeable persons please expound on this, I would like to know more too...
Appreciate the insight -- I hope someone else can expand. To expound on that though, how do you transfer a ROM to the SDcard if you wipe /data and don't already have a ROM available on the SDcard?
I'm worried that I'll accidentally wipe data & cache, but will forget to double-check that I have a ROM on the SDcard partition.
Not to worry, wipe data/factory reset in CWM does nothing to the sd card partition everything will still be there including the ROM file you transferred over.
However factory reset from stock recovery DOES wipe sd card data. So back up your stuff if you do this.
Oh and always make a backup in CWM so you have something to flash in case things get crazy
I'm just trying to plan for a worst case scenario -- let's say all the storage volumes are completely wiped, and all you can do is boot into CWM. On my T-Mobile G2 (Desire Z / Vision), you can mount USB storage, copy over a ROM, and install it.
Looking for some sort of equivalent ability on the Galaxy Tab.
Hmm, let me boot into CWM and see if the computer still can read the tabs storage if I plug it in from there...
Also there is always an ODIN flash.
Nope no dice, i suppose if you were in that scenario ODIN would be your option. I'm not sure if there is an ODIN flashable of stock 3.1, I know there is a .zip i always keep it for emergencies.
Sorry I miss read, there is no ODIN flash.
Would the worst scenario is when you don't even have CWM on the tab?
ODIN flash would probably be your last resort. I am wondering if anyone has run into the worst scenario and got the tab back to the factory stock ROM.
your are right FilltheVoid. if things go completely wrong and you have no backup or rom to flash. Odin will be your savior. You can flash stock roms with Odin bro.

Hey Task, do you know where I can find a stock ROM for pt7510 that is ODIN flashable? Ya know, just in case.
Well anywho, I think the point of this is, If you read and follow directions carefully, make backups, and read some more, you will not ever be in this scenario. And there are good, knowledgeable people in this forum that are willing to help you in a bind.

Even though the question is to Task, i will answer it with whatever i know.
1. http://droidbasement.com/galaxy/sys-backup/hc_31/ - But i read somewhere that this is the ODIN flashable stock of I/O tab
2. ROM | 001002-P7510_KME_Restock.zip - ODIN flashable Stock UEKME ROM
Or you could do:
Boot cwm, then
adb shell
mount /data
mkdir /data/media
adb push stock.zip /data/media/
and flash with cwm
Voila !!!
thank you!
you just saved my tablet! thank you.
i managed to brick my tablet (or so i thought) by an interesting combination of things.
first, i installed Alegro graphing calculator. then, i encrypted my tablet. then, i tried to backup my apps, using titanium backup, and whenever it got to alegro, it crashed superuser, market, myapps, googleapps, calendar, acore...a ton of stuff. so i told titanium to ignore it and backup everyything else, and then i went to the market to try to uninstall. no dice..it force closed everything again. so i went to the settings and tried to factory reset. i went through the steps three times, and nothing happened...the tablet rebooted and was the same as i left it.
so as a last resort i went into clockwork and wiped data and cache. tried to boot, and it was stuck on the Samsung Galaxy Tab 10.1 screen.
rebooted..same...waiting hours...same.
i could still boot to odin and recovery, but i didn't have a zip on my tablet, so i couldn't flash anything. i never thought of using adb to push the zip! but this worked perfectly! (after installing the drivers again on my computer).
thank you thank you thank you!

Hey 2 questions about the restock ROM:
1) Can it be flashed over In Paris V5?
2) Can it be flashed with CWM?
Update: answered this myself: Yes it can be flashed over in Paris, and no, it has to be flashed with Odin.
I still have a question though: This is not CWM, but is it the stock recovery or do I need to flash that too? Sending the tab in for service (newton's rings)....
This is what I was looking for. I have a slow internet connection, and Clockwork was still working, but nothing else was. Flashed Task's ROM v8... it's looking good so far... You rock, dude.
This worked for me this afternoon! Was stuck in a constant reboot after thinking that the samsung update would be a good thing. Gave thanks!!! Ordered the 30 pin adapter and now dont even need it. Will come in handy though I am sure.

This maybe complete rubbish, but I can report a similar issue with the Galaxy S2.
When I install a new ROM, I usually do this:
1/ factory reset
2/ wipe cache
3/ wipe dalvik
4/ Mount ALL the folders, then format each one
When I do this and try to mount USB storage, it says the same error message.
If you then fire up ODIN and push another kernel to the phone, everything works fine. I know its something I am doing wrong, but no idea what!
For you, the solution is to use odin to push another kernel across.
