Can someone post there "mount" command output a shell?

I'm trying to debug why /data won't mount. Can someone post the output of there mount command?
Here is my output and sure enough /data is not mounted:
/ # mount

However if I do a ls on / I see /data and it does have files there:

Thanks for the quick response!

What rom are you running on? There are serious mounting/adb issues with the latest gingerbread leak

Do you happen to know the equivelent of /etc/fstab in android linux? I know a tiny bit about linux, but not anything android specific.
have been trying various mount commands with no success. I think the problem is that there is already a directory called /data that has data in it (presumably part of the rootfs) when really it should be mounted to /dev/block/mmcblk0p1. I'm hoping an ODIN flash will fix me up.

[Q] I think I accidently overwrote my sdcard file

I think I made a mistake trying to use adb shell.
Was able to get my Evo shift 4G rooted. That went smoothly first try. Did the steps manually. Wanted to downgrade to 2.2 from 2.3.3
Was trying to copy misc.img to SD card root
adb push misc.img /sdcard
Click to expand...
Click to collapse
and it seems to have copied misc.img to a file called sdcard overwriting whatever was there before. Sorry for the noob question, but was the sdcard file a file that tells how to mount the sdcard device?

How can I fix my mistake? I tried Ext2explore to read PG06IMG looking for the file, but I didn't find it.

Looks like you did . Did you have a backup copy of the card?

After some more reading, I figured out things were not working correctly. (Well obviously. lol) Not sure what the file called sddisk was, but I just deleted it. The path to the files on the sd card, was actually at... /mnt/sdcard/
I modified this line...
dd if=/sdcard/misc.img of=/dev/block/mmcblk0p17
Click to expand...
Click to collapse
To
dd if=/mnt/sdcard/misc.img of=/dev/block/mmcblk0p17
Click to expand...
Click to collapse
and the command worked.
After I did that, the rest of the downgrade to 2.2 worked well. I'm happy.
Another strange occurrence. There was another instruction.
rm vendor
Click to expand...
Click to collapse
This wouldn't work for me. got the error. 'rm' is only for files, not directories. i had to use the command 'rmdir' on the empty directory.
In the end I do have success with the downgrade. permanent root.

Well glad you got it sorted out.

yep, that's what I figured but it was still worth a shot. :x
You'll need root. If you can get it before you have to surrender that tab, it'd be great.

run this one:
Code:
cat /proc/partitions
and this one:
Code:
fdisk -l /dev/block/mmcblk0
this command would be interesting too:
Code:
cat /proc/cmdline
And if the file exists execute "adb pull /proc/config.gz"(or copy it via rootexplorer) and post it here. It's the kernel-config

Cool - these are btw mostly generic tegra names, while most are probably obvious I've "translated" them below.

There's no standard "dos" partition anywhere, so that won't work.

At least cmdline is actually protected from normal users in newer kernels and same with config.gz I believe. Worth a shot though. (FWIW, usually tegra bootloader fills in kernel cmdline rather than hardcoding it in boot.img )

4096Bytes are missing. Maybe the bootloader+PartitionTable at first bytes of Nand :)
Did anyone of you try if there is an bootloader-mode(the usual key-combinations)?

Partition sizes
Could you/someone please post a df to see the size of each partition, I wonder how much of the 8GB are available and how much is for /data.
Thanks!

Filesystem Size Used Free Blksize
/dev 487M 32K 487M 4096
/mnt/asec 487M 0K 487M 4096
/mnt/obb 487M 0K 487M 4096

/storage/sdcard0 5G 4G 1G 4096
/mnt/asec/com.lexi.android-1 3M 1M 1M 4096

Is there any way to creat a extra partition or at least to change the size?

I don't believe so or someone would have done it already.

Just a bit of an update on these from what I've found. MDA is listed in the fstab as encrypted data.

Seems they just stuck RDO (radio) in the middle at p4 so everything else just shifts down, and up a p#.

Also worth mentioning for both N7 variants (and apparently Tegras in general), mmcblk0boot0 and mmbblk0boot1 are continuous and contain 3 partitions: BCT, PT and the start of the bootloader. BCT takes up all of boot0 and the beginning of boot1. They are encrypted and boot0 is where lockstate is stored. For more info check out my BootUnlocker Script thread.
Credits to lilstevie for that information.

USP is only staging Area for bootloader flashes not the bootloader itself...
Is the per partition on all N7 the same or are there differences from device to device, so that I can´t use the per partion of another N7?

Having issues decompiling the Boot and Recovery, code suggestions

[Q] Can't locate the Symphony W85 recovery partition

Hi! Good day to all,
I am new in XDA. I am Moniruzzaman.
Please help me!!!!
Symphony Xplorar W85 (Code name: l3356) Manufacturar: Symphony
I want to flash my CWM touch recovery img to my phone. but I couldn't find the recovery partition
I've rooted my phone using framaroot 1.9.1. I have upgrade supersu and installed supersu pro 1.94
I've dumped my stock boot.img and stock recovery.img using dd command dd if=/dev/bootimg of=/mnt/sdcard/boot.img [3.6 GB in size] and dd if=/dev/recovery of=/mnt/sdcard/recovery.img [3.6 GB in size also] respectively.
I've successfully extracted all the necessary file (kernal, ramdisk and other) from stock boot.img not the stock recovery.img and manage to create the recovery.img (CWM Touch recovery) for my device (l3356) which is 6.11 MB in size
I flashed it from sdcard using dd command again "dd if=/mnt/sdcard/recovery.img of=/dev/recovery"
It didn't work. I could not reboot into recovery. My phone automatically go into normal boot mode. Then I find my mobile gsm was gone.
After that I restore my stock recovery.img to /dev/recovery using dd command.
finally I 've tried to flash my cwm recovery.img to mmcblk0 using dd and it was horrible. I got steady hang.
Luckily I 've manage to replace my phone's motherboard and got a new one (as I've warranty)
my device /dev/block/mmcblk0 contains many critical parts of the phones file system such u-boot, /boot, recovery and other bootloader related components.
Now is there any one who can help me flashing CWM touch recovery img to my phone. I couldn't find the recovery partition
Details are for analysis. Please help me solved the problem...
My device (Symphony Xplorar W85) build.prop is attached here
Now There is no file named /cache/recovery/last_log in my mobile as it is new.

I dont have a by-name folder but only by-num, which really doesnt help

stock rom???
do you have the stock rom or any custom rom because i cannot find anywhere... i need it please :'(

CWM Recovery Non Touch version
I don't have stock rom.
I have dumped stock bootimg which is 3.6 GB in size. It also contain the whole image of 4 GB partition of Symphony W85. So if you use dd command then it will copy the whole image to your phone. I have tried it on my phone and it worked.
Why are your looking for stock rom?
Symphony W85 CWM has already out on net [search google for "Mobile Solutions: Symphony W85 CWM Recovery" As I am new, I can not insert link here until i post 10 message.
Best of luck

[Completed] [Q] Need help finding recovery partition

I've got a fancy new Asus K01A and as far as I can tell, I'm the first to try to root it on xda, or at least the first to try to make CWM for it. When you're making CWM, it's rather important to know exactly where the recovery partitition is, in case I need to flash something from fastboot to correct something stupid it did. Problem is, I can't seem to find a partition for recovery, here's a bunch of partition information I gathered:
