[Q] Muppet in need of Help

Hi,
I've been a right royal idiot and have spent 2 days trying to get my SGS back into working order.
Flashed Bionix v1.7 Rom (didnt realise it was Vibrant), worked great with the exception that the headset socket logic to be back to front. No audio from external speaker, if you plug in headset you could then external speaker started to work.
I therefore flashed back my origonal ROM with ODIN but on reboot the update failed with can't mount /dev/block/mmcblk0p2 on /data (Invalid argument). After then reading the notes (Yep noob mistake) I realised I should have removed the voodoo lagfix the Bionix ROM had before flashing a new rom.
Having done some investigation it looks like mmcblk0p2 is an j4fs filesystem but nothing I seem to do seems able to change that. Tried to mkfs and ext2 filesystem on it but it seems to be working then aborts saying it wasnt cleanly unmounted and to e2fsck the partition, which I try and it errors with unable to set superblocks on /dev/block/mmcblk0p2.
Any and all help greatly appreciated

Find a full rom that have dbdata.rfs, cache.rfs in it. Flash via Odin with repartition ticked.

JM8 will restore the things your missing

I have tried that, Odin runs through with no issues, but on device reboot it errors with the same. I can boot into clockwork recovery and adb shell. Its really weird, I've done a complete dd dev/zero over that partion. I've mounted it in windows and formatted via that and yet when I reboot and look at the partition via windows, all the data is there. There were a couple of other partions that were j4fs (/datadata) if i wipe that partion using fat.format, when i remount it it mounts as rfs instead of j4fs (great), but when I do the same with /data (mmcblk0p2) it says success on format but when I mount, it still mounts as j4fs...any other ideas?

Will try JM8 and let you know
Tried JM8 Odin complete succesfully, on reboot complains about CSC (multicsc : can not access to /system/csc/KOR/system
copy_common_data E:Can't mount /dev/block/stl11 (invalid argument))
cant do anything with stl11 in adb, complains no such device (although /dev/block/stl11 file exists)

I've managed to recover my SGS with a flash of JPU which is a low level package including repartition with 512.PIT. Here's a download link to JPU if it helps. It's a 3 part flash in Odin: http://www.multiupload.com/L79EDKJIG3
Good luck!

Just tried this and error is back to origonal ie cant mount /dev/block/mmcblk0p2.

You didn't accidentally store those files on your Sim or SD card right?
(I know, beginners question but just to be sure )
So you can't use your phone at all atm? Just stuck at recovery screen?

I had this same problem last night in the end used odin 1.7. With older firmware and pit (512) files doing a full repartition and reflash with csc. And modem files this was a jp4 set i believe.
This would not then upgrade in kies so i flashed a jpy firmware over the top just the firmware file this time. Not sure but i think i could have skipped this stage and restored from the clockmod backup. Can anyone confirm?
Then i rooted the phone again then flashed a kernel with clockwork mod support and was able to go to recovery mode and restore with the back up i made before i started messing about, though i suspect a titanium backup or similar would have worked just as well.
Hope this helps you at one point last night all I had was an icon with the phone and a computer thought I had really bricked it this time but given what I've done over the last couple of weeks i am not sure that's even possible.

Just tried with Odin 1.7, the JP4 romset still the same error on mmcblk0p2.
Just for avoidance of doubt in case I'm not doing this correctly,
In Odin I have Re-Partition, Auto_reboot, and F.Reset Time checked, Dump, Phone EFS and Phone Bootuploader Update are not checked. I'm using s1_odin_20100512.pit, and have tried Various European Roms including all the ones mentioned so far.
Fundamentally is the problem not that the filesystem type of the internal SD partition is j4fs? It seems the kernels dont know how to mount this type of filesystem, and for some reason I seem unable to change this. I cant even delete/format the data in these partitions.
cronoz, I believe mmcblk0 is the internal SD memory, which has 2 partitions. The first is a 2Gb Fat partition and the second is a 5Gb ext4(j4fs) partition.

Try using hardcore's kernel. In recovery mode try to disable lagfix.
Good luck

Yes the file system is the issue but repartitioning should reset that at lest it did for me last night. But only once i found a complete set of files. A *512.pit mine came with odin the main firmware in the pda box the modem file in the phone box and the csc file in the csc box once i had that mine refreshed just fine. If you have the right combination of those then I'm not sure what else you can do tbh

Well this thas put me a lot further forward thats for sure. So i Flashed speedmod-kernel-k13a-500hz.tar. This now bootsl the SGS. It complains bitterly, force closing just about everything, but it does boot. Just about all apps force close, but I can set debugging mode and get in via adb (although the roms not rooted (JP4) :-S).
I can boot into recovery and choose the speedmod Lagfix option. It correctly identifies that /data is ext4. I disable lagfix and the new config is set to convert data to rfs on next reboot. I reboot and it goes through the conversion, backup of /data /datadb and /cache, it then generates md5 checksum and the aborts saying there is not enough space on internal SD. Not sure how to fix this part. When I enable debug mode I can see 2 partitions in windows a 1.8Gb and 5.3Gb, Both are empty apart from my update.zip in the 5.3Gb partition.
EDIT: Also tried the Yes, with factory reset without backup option, this seems to work but on reboot /data is still ext4 :-S
Any other ideas how to proceed now?
Any Full Roms with the speedmod kernel you could recommend?

you can try darky's resurrection rom which is a complete rom with pit file 502
http://forum.xda-developers.com/showthread.php?t=940671
If that fails you can also try to flash jpy or js3 with the 802 pitfile
hmm i think the 2 partitions are the main problem....... It's kind off strange that you only can see the update.zip. How did you create the 2 partition???

Ive been trying darkys res rom, the only problem I think though is that it does say that lagfix has to be removed (ie not ext4 partitions) before installing, and that I suppose is the underlying problem of why I cant get it to work.
I just realised it wasnt 2 partitions, its the Internal and external SD cards, the 1.8Gb seemed to be corrupt, I managed to format it via the SGS menu and it shows the correct 8Gb now.s
EDIT: Hmmm just noticed something, its seems that although it appears I can delete and add files to my internal SD card via windows, it doesnt actually do anything on the card. This very strange :-S

[Q] HELP! Cant mount /sd-ext

Guys,
I dont know what I did but I can no longer do a factory wipe.
CMW says "Error: Can't mount /sd-ext" Ive tried reformatting / repartitioning the sdcard. it just keeps saying cant format.
I tried CWM 2.5.1.2, then i even flashing it again and tried a 3x version of CWM.
I just wanna be able to flash roms again. Please help
ANY HELP / SUGGESTIONS IS APPRECIATED.

Hey, there are a couple of threads that talk about
"Error: Can't mount <something>" ... you should check them out. I also recommend doing a search for "Cant' mount" you will find a lot of threads talking about a related problem.
Here are some, I hope they solve your problem:

ive tried all of those
my issue isnt mounting the sd card but rather the sd-ext partition. ive rrad all these threads and tried everything stated.
Also. it seems i have 2 different CWMs. 2.5.1.2 when i flash into recovery from ROM Manager and 3.0.x when i go into recovery manually.....how is this possible and how can i fix this?

you shouldnt need to mount the external sdcard in CWM. you flash things from the internal sdcard

when i try to wipe data to flash a new rom it says
"
Error: Cant mount /sd-ext/

im unable to wipe data so im currently unable to flash anything

thats completely normal.
wiping data has nothing to do with flashing anything.

CWM is unable to mount the sd-ext on our phones because it has a different location (sdcard/ex-sdcard) than most phone (mnt/emmc)

HELP!!! Link2Sd not working after recovery

I had a lot of CWM backups on my phone.
so I thought Ill do one nandroid backup of my current phone and then recover each of the previous nandroid backups to see what they actually are.
Then when I recovered my latest backub (done two hours ago) Link to SD doesnt seem to work. Before I was doing this whole CWM backup check everything was fine.
All the settings are as they should be too. only the apps linked are not theyre anymore. The apps only moved to SD are still available.
When I open Link2Sd and choose FAT partition (cause thats what my 2nd partition is) it says:
"Mount script error. Mount scipt cannot be created.
mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: Device or resource busy."
Can someone pls help me. I really need my phone to be properly working again when I go to work tomorrow.
You can see more details about my phone in the signature, if thats of any help.

Your second partition has to be EXT. Try using a terminal with the following command:
Code:
tune2fs -l /dev/block/mmcblk0p1
It should tell you bad magic number as it doesn't understand FAT32
Code:
tune2fs -l /dev/block/mmcblk0p2
Should work as mmcblk0p2 is the second mountpoint for the EXT partition used by A2SD, S2E and Link2SD.
Your nandroid backups are on your FAT32 partition -- back that up to your computer (copy all files or make a disk image). Then repartition the SD card using CWM, turn off phone, now copy your files back to the new FAT32 (which will now be partition 1). Now reinstall SD card, boot in CWM and restore

I've had the same problem. I noticed that CMW restore has formatted the sd-ext in ext4, and stock kernel does not support EXT4.
Solutions:
_ flash CF-root
or
_ take your sd, put it in a pc with an adapter, backup sd-ext, format it in ext2, restore the content

link2sd not installed
why link2sd cant installed in my phone after reboot?:crying:

Is this real ?
1) Why CWM restore formats sd-ext? Why is it not limited to work on internal memory? -> If this is true should be a good thing to remove always SD when using CWm... oh... no... this is not possible... If I remove it how can a restore be done from an sd ?
2) Reformatting sd-ext to original ext2 (compatible with stock ROMs) and restoring content (copu\paste) is s working solution to fix this problemi? Anybody can confirm this ?
thank...

I had the same problem, link2sd could not recognize the partition after a nandroid backup.
I'm using a HTC Explorer and made a backup on the stock rom, I'm new to this whole rooting business and I was hoping someone could help me get things back to the way it was before the backup.
Thanks in advance

When i try to mount internal so i can try to flash a rom it wont let me it says " E: Cant mount /dev/block/mmcblk0p35(file exists)" and the same with sd-ext but i was able to mount internal sd on to the pc where i saw my nand back up file can i use this to flash everything back thru fastboot? Any solutions to this???

Nm I put the Rom on another sd card and mounted it even though I got an error and it install. Huge relief I was about to give up lol.

[Help] Internal SD card failure

Well, I can say that I spent hours on hours trying to search for a solution with no luck,
The internal sd card of my Galaxy S GT-I9000 is corrupt.
I get E: format_volume: rfs format failed on /dev/block/mmcblk0p2 when im trying to format without sdcard inserted.
What I have managed to get after doing everything I can from my own knowlage and from the internet:
100% Working phone with ICS 4.0.3 only with 2 partitioned sd card(reiserfs and fat)
did everything in here:
http://forum.xda-developers.com/showpost.php?p=31017954
http://www.youtube.com/watch?v=zdMhYYdMB08
also flashed multi-csc firmware with pit(JVU/JVZ) after format everything(except /boot) through CWM with no luck.
main goal:
100% Working phone WITHOUT SD CARD
I thought maybe someone could tell me if this could be solved within software itself or only FLASH IC replacement?
got linux and windows systems so guides with commands involved wont be a problem.
THANK YOU!
