[Q]Can´t mount /Data on my Nexus S - Nexus S Q&A, Help & Troubleshooting

Im quite desperate here.
Last weekend i rebooted my nexus s, it was doing allright but after the reboot it got stuck on the bootanimation, so i rebooted it again.
After that the phone went black and some white letters informed me that the /Data partition was corrupted and couldn´t be mounted again.
I tried restoring with Nandroid but it didn´t let me because the /data partition can´t be mounted.
I tried flashing with fastboot but again, the /Data partition can´t be mounted.
What I want to do is to erase that stupid /data partition and recreate it so i can flash it with fastboot, or at least mount it.
I tried that with parted on ADB shell, but the stupid partition won´t leave the partition table, neither any of the other ones.
I´m quite pissed since I leave in Argentina and Samsung won´t change my phone for the problem.
Does anybody had this problem before and could solve it?

You can try "fastboot erase userdata" but that may not work since there is possibility that the flash memory is failing.

I´ve already tried that, but it takes me nowhere.
hoewer thx

Sad to hear that... most likely you are getting flash memory failure (board failure). Got any warranty left?

[Q] Help ~~! Semi-Brick ~

Well here it goes.. yeah im a noob to somehow have accomplished this, i have semi brickedmy phone, the internal flash on my phone got completely wiped, /boot /misc /system /data etc... all gone, just one big 8GB partition, cant restore any roms or backups, any ideas? help?
Can you install a new ROM through recovery?
nope cant flash anything since the partitions are gone there is nowhere to flash anything.
update: so i have recreated mmcblk0p1 -> mmcblk0p8 - was able to flash the stock rom, and mount all the partitions but still phone boots straight to recovery... im guessing it has to do with some of the partitions not being recovered with a backup like /misc anyone have any idea?

When you do a factory reset - besides wiping, it sets up the partitions even if there is not a ROM installed. Do that and try to boot up after that.
If it does not start up, then try flashing the ROM again.
If that does not work, I think there is a firmware file in the Dev. section that I believe has everything. Carefully follow the OP directions if you go there.

[Q] Recover cant mount /cache

recently my phone ran out of battery and when i connected to a power source and turned it on only to have it boot into recovery and in recovery gave me the error cant mount e:/cache, tried to do a nandroid and it wouldnt let me, then after a couple of reboots it booted into the rom, now every time i restart my phone it goes into recovery and does the same thing, i updated to the newest Internal recovery, but it still does the same thing. Any Ideas of what it could be?

sounds like what happened to my first phone, probably ended up wiping all your internal partitions , had to go in parted with adb shell and recreate all the 8 partitions on the internal memory to be able to flash anything on the phone.

[Q] Help! I think im bricked

Hey guys,
The problem all started last week when I encrypted my tf300. For some reason it did not occur to me that this would be an issue when I started the process of rooting today. I used the asus bootloader unlocking tool and got fastboot to work long enough to flash cwm but when I tried to flash from sdcard it said that it cant mount sdcard. This is where I messed up. I realized that I needed to format data so that I could unencrypt. Booted to cwm and formatted system and the two others that are there but it refused to format data. Now it boots to the Asus screen and recovery does not mount sd. fastboot devices list is empty same with adb devices.
Any ideas??
Thank you
So I guess my question is how do I erase or format data partition so that i can flash a rom.
any help is appreciated.
thanks
Switch on with power + VOL down then VOL Down, then VOL Down twice to move across to WIPE DATA, VOL Up or power should select it for you.
when I select wipe data the device boots to clocworkmod recovery.

Ah you will probably need the standard recovery image as there is probably some lock on it.
http://forum.xda-developers.com/showthread.php?t=1668173
You will need to ask XpLoDWilD for it then flashboot it back onto there and try again?
ok ill give this a try. hopefully i can get fastboot to flash the image. i had a hard time getting clockworkmod on there.
thank you

I've been flashing recoveries all day and had no issues with it.

Did you format:
System,
Cache,
Staging
Data
then wipe cache
then data/factory reset
then advanced and wipe dalvik
i was able to format system cache and staging but when i try to format data it says:
error mounting /data!
skipping format...
done.
says something similar when i try to mount sdcard so that i can flash .zip files

Have you tried Factory reset from the main menu?
when I choose wipe data/factory reset i get:
--wiping data...
formatting /data...
error mounting /data!
skipping format...
formatting /cache...
formatting /sd-ext
formatting /sdcard/.android_secure...
error mounting /sdcard/.android_secure!
skipping format...
data wipe complete.

Standard recovery might let you wipe it.
Just had a look on XDA and this might help you?

Hello Everyone
To flash a new ROM you can do as follows:
boot in Recovery
format cache partition
from your PC use adb to mount /sdcard as tmpfs:
adb shell mount -t tmpfs none /sdcard​
put your ROM on the (fake) sdcard
adb push <your rom> /sdcard​
use the recovery to flesh the ROM as usual
This worked form me.
Sorry to be late...

i am going to start by apologizing for being such a noob. Thank you so much for your help.
I am not very familiar with adb and fastboot i have only used it a couple times and this is when im being led through it by some forum on xda.
when i run the first line i get
error: device not found
from what i have seen this is a driver issue?
i have used this same stuff to help root my phone a while back. could that be an issue?
i tried the commands while the device was in recovery and while in fastboot mode.
thanks again

Reading from that thread the only way to wipe encrypted image is if you boot into it, not sure the standard recovery will do it
When I found out that the encryption was the problem I tried to do a factory reset in the settings and it just booted me into clockworkmod. I should have just flashed stock recovery then.... lesson learned.
I hope I didnt make an expensive paperweight.

Yours is a bit more difficult but I have managed to mount and push files in recovery to my sd card.
Need to work out how to format yours now.
Sent from my GT-I9100 using xda premium
could there be a way to partition and do some sort of "dual-boot"
just a random idea.

TF101G boot loop

Hi @all
my TF101g sudenly got into bootloop at Eee logo. I can get into TWRP, get ADB connection to PC, tried everything I could find here in forum (PERI etc), but nothing helped.
At trying to format Data partition with ext2, I get an error. It seems that my Data partition is corrupted in such way that it can't be formated.
Any ideas what could I try?
Can I flash a stock ROM somehow?
I can flash from TWRP, but it does not seems to work. Tried KatKiss 4.4.36 (this one was installed at the moment of sudden bricking) and Android Revolution - none goes passt the Asus logo.
P.S. forgot to say how it happened - it rebooted at connecting it to the power source and after reboot got into loop.
Maybe you can go to twrp wipes, advanced wipe and than only click on data, than on the right "repair or change file system" I dont know why you wanna format to ext2? All my stuff is ext4, but I dont know if I changed it in the past.
TWRP wipes didn't help, and now it is too late to do anything. I tried to flash stock ROM, and I've lost TWRP. Now I have just the boot loop and no ADB, nothing.
weird, can you try to repair it in apx mode? (Volume Up & Power when the tablet is off). Maybe to flash stock rom again, or install twrp.
In 2013 i had the same problem in my tf101g, not did have solution here in xda, and not have. I tried solve the problem with myself. I not remember more. But, you will have to format your partition for ext4, then ext3, then ext2. In adb. Put in recovery, and go to pc. I not remember the codes. I will try to remember.
Hi mendez,
I found that solution too here in the forum, but it didn't work. I always got an error at formating, something about value too large.

Wierd recovery problem

I got a nexus 5 off of eBay, the seller said he had tried to root it and failed so I thought I would have a crack at it.
I thought it would be an easy restore but I ran into a few problems:
Phone originally came with 6.0.1 installed.
On android 5+ I could not access the standard recovery screen, and when I pressed power+volUp it just said formatting /data and would not move from that.
Rolled back to 4.4 and I got into the ususal recovery screen.
Tried to do a factory reset, but it again stuck at formatting /data.
I left it the entire night while I slept and it was still saying formatting /data. in the morning, nothing had changed.
Trying to boot the phone normally just left it on the 4 startup screen.
I've tried doing a full flash of stock android with each seperate part manually.
Also /data is unable to be mounted in any custom recovery, like it is corrupted or locked somehow.
With the stock recovery, it cannot be detected by adb, but in cwm it can.
EDIT: checking the /data folder in adb shell shows it's completely empty, and the same with system even after flashing and flashing again.
Can anyone advise me as to what might be the problem here?
Reflash all partitions manually, including userdata.img file. After flashing the last partition, boot directly into stock recovery and perform a factory wipe, then reboot.
Done that multiple times, I get the same result on stock android.
I don't want to root or anything like that right now, just get it back to a working state.
So you flashed the userdata.img file?

yes multiple times
If you flashed userdata.img multiple times and the phone still can't perform a factory reset, the emmc chip may be damaged.
