Nexus s eMMC dead, or what?

jaani8 · Feb 11, 2014

Unlocked Nexus s i9023 stuck on google logo. Tried to wipe cache/ re-flash in recovery...but unable to mount sdcard. "E:Unable to mount /sdcard"

I have tried: Fastboot.. flashing boot and recovery works.
system and userdata ain't

sending 'userdata' (18796 KB)...
OKAY [ 2.511s]
writing 'userdata'...
FAILED (remote: Write Fail)
finished. total time: 2.539s

On phone screen "Verified EXT4 image!" in red

Odin3 v1.83 with download mode gives write error and on phone screen red txt

KA3...New eMMC Support Fail

Stock android recovery wipe data/factory reset does do nothing.

Sideload...on TWRP recovery.
C:\Users\Jaani\Desktop\adb>adb push rom.zip /sdcard
2788 KB/s (153760279 bytes in 53.839s)

Then try to install zip. Failed, unable to mount storage.

Any ideas?

Lock and unlock bootloader. If still not working then eMMC dead.

Try a new usb cable! I know it sounds a little tooo easy but I had same problem. I finally found that the cable has to be really snug in fit. I mean real tight that it almost feels like it wont fit. It seems that if there is just a slight bit of play the signal gets pooched somehow and then everything reports dead.
Once you get a cable that fits real well, adb, fastboot and the whole nine yards will work and life will be grand again. It took a while and a few returns to Staples and Best Buy and Future Shop til I found the right one and when i did i bought two spare just becuase and I haven't had any problems since.
I just retired my Nexus S in late November (which was my daily driver since it came out) for a Nexus 5. The S is now running CM11 KK4.4.2 and surprisingly much much smoother than JB but there ain't no looking back after having a N5.

Good luck!

Tried 7 different cables. Original Samsung, Nokia, LG's and Kindle. No success. =(

Hi, i have like problem.

I think device has incorrect fstab and partitions configuration.
Nexus S has flash memory chip, parted to some blocks.

Code:

ls /dev/block/platform/s5pc110-onenand

mtdblock0  mtdblock1  mtdblock2  mtdblock3  mtdblock4  mtdblock5  mtdblock6

it is eMMC?

Try to Relock the Bootloader and then again Unlock it, then try all you did if failed again then eMMc is dead.
There is 1% chance of fixing your phone even by a technisian. Because he needs to pull out the dead eMMc and paste a new one. As nexus devices dont support SD card otherwise you could have flashed your device over SD card. The eMMc on Nexus is pasted one so its very difficult to plug it out sucessfully.
You may need to change the mainboard of your phone if You need the mainboard contact me...
Good Luck
