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.

After trying different roms and testing different things i realized that a full wipe does not clear everything of your current setup.
If you use root explorer for example and just take a look at your folders and files you will see that there are many files left from older roms.
What is the fastest way to make a totally clean installation with a custom rom (cm9 nightly or rr for example)?
I found an older tutorial here but i think it might be outdated.
Is there some kind of script that i can flash before installing the new rom (that cleans everything but efs files and recovery files for example?).
Or do i have to get a sammy stock rom with 3 parts and pit file and re-partition with odin and flash pack to a custom rom right after ?
in CWM
under mounts/storage
format system,cache,data
then flash rom
Really clean install? Flash rom through Odin. Everything will be wiped.

No as you said it just clears data and cache, that is wiped with full wipe /factory reset anyways. And system is also just the system folder.
The other folders in your root will not be touched by this and will still remain on the phone. But i cant really tell if they are used or not anymore. I can only tell by the content and the creation date that of the folders and files, that a lot of these have to be from older setups.

What kind of firmware do i need then? I think if i flash without the re-partion tick in odin options the old files would also stay there. and i need a firmware with 3 parts to flash because you need a pit file to do that.
Ofc i would like to have exactly the same partition sizes as before on my phone if i have to repartition.
So i guess i need somebody who has some knowledge with odin and 3 part firmwares.
download the stock rom from samfirmware.com(after signup)!
flash the "md5" file using odin
after fresh install of stock rom, goto settings>storage>format usb storage and format sd card if u have one!
then u can do a factory reset again and you have a clean wiped phone!

Are you sure that a 1 part firmware from sammobile will wipe all the internal data and not just update and overwrite the new ones? (im not talking about the sd card, im talking about the system data that you can just see with a root explorer for example).
If you're performing a wipe data/factory reset alongside wiping the cache and Dalvik cache, you are performing a clean install. The residual files you're seeing are stored on the internal storage (the /sdcard partition), if you wish to clear them, go into recovery, mounts and storage, and format the /sdcard partition. Viola!
Also, wrong section. All questions should be posted in Q&A. Flagged.
screamworks
I attached some screenshots now about the files that i mean.
Im not talking about the content of the internal or external sd card.
Look at the misc, lib ,res or proc and preload folders.
Also the script files.
Some files might be related to the kernel settings of course.
Im trying to go on a stock rom now and call "*2767*3855# " for a hardreset and see if that works
EDIT:
Nope the hard reset didnt work, all the files are still there.
Where do i get a ics rom with 3 parts and a pit file that i can temporary install to clean my root folder? or is there a tutorial here somewhere could follow?
External SD not visible after new ROM installation
I rooted my galaxy s2 just a day before and faced an issue. After rooting I installed jelly bean 2.6 ROM(Resurrection and remix) and found my GPRS not working and then I did a factory reset, but unfortunately phone got dead and then I removed the battery and re booted after some time. This only restored 98 applications out of 113 in this new ROM. However, I re flashed the ROM again and all the applications got back to normal, but my SD card was not to be seen after this second flash, before factory reset my external SD card was readable(with the new ROM)

the external SD it's mounted on /emmc so, there are your files. You can access to this folder with any file explorer (even the stock one). Just open the file manager, select the "mnt" option on the top, the one between the Home icon and SD icon, inside you can find the emmc folder.
Well i guess i could compare my files with the files of somebody else with rr and delete some of them manually

Swyped from my Galaxy SII
i am also interested in this. Am new with galaxy s 2 well actualy its not even home yet =D but i got experience with HTC HD2, isnt there somethink like Task29 or similar or its odin exactly the same think, so that what am looking for? And would it be good to manuali format it with a pc, like when i conet galaxy s2 to pc and then via program format the comlet internal memory fat32 and ext3 or how it is made at that phone
ass this is already some time, ODIN is the best option on gs2, had my problems on start caus of imei restoration, was confuzing to learn all the stuff i needed as a brand new starter with it =D but got it done, but am suffering the loss of volume buttons, had to do an usb jig for 5cent :good: prety cheep jeh, now am on AOSP Neatrom 5.8 A.KK 4.4.3 slim, recomending it =)
I've been having alot of issues, lag, freezes, reboots, and ive been having these issues on a few different roms ive tried. I had Been running the paranoid android one from Jamied81 and it worked great but then i switched around and on any rom including the PA one, and other cm10 roms, im having the same issues, So There must be something wrong with my phone... i guess?
How can i completely wipe clean and start fresh? because ive been wiping data, cache and dalvik cache but thats not helping...
Of course i could go back to best buy and cash in on my warranty.. but i really dont want to do that...
thanks
Well,
It depends on the level you want to take the "cleaning" too...
Data, cache, dalvik cache, and stats are a normal cleaning, and used by most folks to get an average clean.
Some roms even state to do this 3 times or more to be sure.
Two additional steps are needed to get the device "clean". and it involves moving everything off of the device to PC storage, and wiping the following two areas.
( by everything, I mean "anything" you want to keep. pictures etc.)
First, the SD card. As the device uses this memory location for cache of files, and bits of user data, it can be a source of misery when bouncing between roms. so a complete format to FAT32 on the PC will wipe this card clean.
Second, and my personal favorite, is wiping of the internal card space, or the EMMC partition.
This is performed through the recovery, under the advanced options menu, in the format sub-section.
Effectively, wiping the emmc "will" remove all rom data from the device, above the normal data wipe level, and leaves the device empty.
Note: the new rom will re-populate the needed files to run the rom upon the first boot cycle.
IMPORTANT !!!
If moving files back to your device from PC, you must ensure that they are clean too. It is very easy to forget that many files contain rom specific data, and should be avoided as a restore function, especially APK's....
The partitions from the last rom will remain in place, but they will be overwritten by using odin to restore the device. ( if you wish to restore the factory rom architecture )
If odin or kies are not used, the rom partitions remain, but are empty anyway.
"WARNING" !!!!
Although this method is considered safe, you "will lose "any" data or files left behind on the internal space of the device, or on your External SD card by formatting.
And you must place a new rom to your External card prior to placing the card back into the phone, and use CWM or TWRP recovery to flash a new rom in recovery mode. (unless odin or kies are used to return a device to stock condition)
Note: (no pun intended)
This method will "not" touch your recovery, Unless using odin or kies to push a non-rooted rom to the device, and the user must choose carefully when selecting any firmware image to flash.
It is up to the user to restore the factory partitions by flashing a stock odin rom, unless the last rom was a "stock" rom. (Note: kies may be used as well, but Odin is the most common, and works well )...
The standard recovery flash can be used, and is advised if you want to retain root...!!!!
"WARNING" !!!... THE USE OF ODIN OR KIES TO FLASH A STOCK FIRMWARE IMAGE WILL REMOVE YOUR ROOT, AND RECOVERY, FORCING THE DEVICE BACK TO A STOCK STATE....( choose carefully as you select any image to flash using Odin or Kies, as these roms are likely "NOT" rooted roms, and will jam you up)...
I hope this helps you.
Please ask if you have any questions, "before" attempting this procedure... PM included.
And could the Mods please move this thread to QA ? Thank you.....g

While i've seen and like the rootzwiki method, I prefer to manually wipe and install roms.
For me, it adds back in, that level of control I like to have when changing roms etc.
I'm the " do it myself " kinda user ...but I agree, it's a good system.

True ....and of course, my post was meant in the context of a device having severe problems.
I seldom use that method either, but in a pinch it's good to have available ......and if users see and retain either of the methods we've posted, they can repair virtually any problem going forward.

Thanks for the reply. But, i dont see any instructions... what do i do with the file?
Basically its a one click version of Odin with the files already loaded into it so you don't have to pick anything.
Download it to your comp, unzip the file (I believe?), open the program, put your phone into download mode, connect it to your comp, make sure Odin recognizes it, then click start.
Takes a bit because its a huge process that it's undertaking, but at times its necessary to go nuclear on your phone.
Really should only be used as a last resort to wiping your phone.

I mostly wipe front to back.
Hello,
I have a question. I backed up my stock rom before installing a custom rom. Now i want to install another rom, so this time do I also have to back up the rom or its already backed up as I did it once the first time? So now that if I want to move to a new rom, i just
Select Wipe Data/Factory Reset. Confirm on the next screen.
Select Wipe Cache. Confirm on the next screen.
Select Advanced and then select Wipe Dalvik Cache.
and I should be good to go? Any other steps?
Best wishes,
Marc
Nandroid makes a snapshot of your entire phone, so you can go back to the exact moment in time when you made it.
Unless you think you'll want to go back to the current custom ROM you are using then no, don't bother.
Factory reset won't wipe the system partition, you would be better off flashing Philz recovery which includes a wipe option for use between ROM's. It's a good idea to have the right modem & RIL for your country ready just in case your new ROM has the wrong modem included..
Make sure you have backed up the entire efs partition to your pc, dropbox etc.

Just copying the folder across in explorer won't save you if you need to restore, use Mike Skip's SG3 tool, the app from market or again Philz recovery to snapshot the entire partition. I'd advise having at least one version you can flash via odin.

and I should be good to go? Any other steps?
Best wishes,

It's not necessary, but you should always back up your ROM before flashing a new one.
It's a personal thing, but I only do so when I do a major leap, like from Sammy to cm or cm to Sammy or one of those to miui or something like that. Other wise I don't because I like having free space on my SD cards.

I think my s7 edge android phone has the autoclean malware.
Malwarebytes does not find any problem, but how can I eliminate the autoclean malware?
That's a windows malware... Seems a bit unlikeley.
If you believe your system might be infected, a reflash of the AP file and a factory reset should clean it up in most cases, but you'll lose all data.

How can I do it without losing all data?
- Copy the contents of your internal storage to a safe place.
- If you're using TWRP, backup /data and Copy the Backup folder to a safe place, you will have to reinstall TWRP as well. Google Play will offer to reinstall the apps when you log in. Also you can backup all app data to your computer with the adb backup command.
- Put the phone in download mode.
- Open Odin flash tool and make sure the cable is good and your device is properly recognized.
- Select the AP file from your current firmware, if it has a USERDATA file select that as well, you won't have to factory restet after. When using Heimdall remove the .md5 file extension first.
- Turn off auto-reboot if you don't have a USERDATA file.
- Begin installing and hope for the best.
- Reboot to recovery and select Wipe Data/Factory reset.
- Phone should be clean now, only restore the stuff you are absolutely sure isn't infected.
If the weird stuff persists, try repeating these steps with the full firware.
