no one knows the answer! weird ha?!

Going to bump this because I have the same problem. At the moment my phone is a brick since I can't put over a rom to install because I can't mount the internal SD card.

Same here, i think its a known issue with ics cwm recovery on sgs2

[Q] Unable to mount sdcard via recovery

Hi
Anyone know why I'm unable to mount sdcard via recovery. This is just happening when I'm using SiyahKernel and HyperDroid's newest rom.
I'm getting this massage (E:Unable to write ums lunfile (No such file or directory)) when I try to mount every time btw.
Déjà vu. Try the "internal sdcard" options within CWM recovery.

I can't find such setting you are talking about
Okay, the only way I was able to replicate your error message was by removing my physical micro SD card from my phone and trying to mount USB or sdcard storage in CWM recovery. Since you're using Siyah kernel, and this message has been present in his changelogs for quite some time known issues: only external sd is mounted over usb in CWM recovery., I expect said issue is still present.

Ahh, I didn't know about that, but this happened in HyperDroid's rom too, but only the present version. Have never happened in the older versions and I don't use a physical micro SD card.

[Q] cwm recovry problem

when i tray to mount from usb in the recovery
i get this message E: unable to write to ums lunfile (no such file or directory)
how can i fix it?
someone plz also when i tray to do mount to sdcard is says
error mounting /sdcard
it works fine from the rom.
My first guess would be that you don't have a microSD card, and you're using a version of CWM recovery which refers to the internal SD card as, wait for it, "internal SD card". If not, what kernel are you using? It could be one which does not support mounting of the internal SD card from CWM recovery.
you probably right so how can i mount from usb? or change it?
i use cf-root karnel
What version of CWM are you using is the question .
jje
cmw v5.0.2.7
Flash with CWM and root kernel not version 5 .
jje
i cant understand you, how can i do mount usb from the recovery
(how can i put files from my computer when i am in recovery mod)?
What are you trying to achieve .
Copy files from PC to Phone or Restore via CWM Recovery or flash a CWM rom .
jje
i am afraid that i will flash a rom and it will fail, and then i will only have access to the recovery.
then i wont be able to transfer the nand backup from my computer to the phone because i cant mount usb in recovery mod.

[Q] Help! E: Can't open /cache/recovery/log

Hi, Im running Neutrino 2.7 Rom. lately I have noticed a problem.. after installation of neutrino ends (using RomRacer latest CWM) it show me These lines.
E: Can't open /cache/recovery/log
(Read-only file system)
E: Can't open /cache/recovery/last log.
Then if I go to "mount and storage" I can see that my emmc is mounted. and if I try to unmount it it tells me
Error unmounting emmc!
This wouldn't be a problem for me if everything was ok except this...
The rom seem to work fine... it passes to boot screen, loads.. but after some time it shuts down, and in order to turn it on, I need to pull battery off and back.
BUT then it turns and stuck in Neutrino's boot screen.
I searched a lot but I didnt found an actual way to solve this. I think there is something wrong with emmc card (internal memory) cause my sd card is just fine. maybe I need need to reparatition my emmc trough ADB? any suggestions would help.
I'm kinda poor and my parents devorced many years ago.. I dont want to tell my mom that my phone is usless
so please, if any one know what should I do.. please dont be lazy to post an answer.
Any body??
Just need some help...
I'm having the same exact problem! If I figure out a solution I'll send it your way immediately!
Found a fix first download automatic bootloader unlock(search google) then do the automatic cwm installer follow instructions. then, download the flashable touch cwm install via cwm and download the project kitchen rom and install it and should be fine like mine

[Q] Why can't I see SD Card from CMW?

While trying to install a ROM from my SD card with CWM I am getting the message "E:Can't mount SD card" I was able to move it internal and install the ROM but I'm curious why I couldn't do the same the SD card. The card does seem to be mounted correctly because I can go to ES Explorer and see the content with no problem. It only seems to be CWM Recovery that can't see it.

when i was watching the utube videos ( of Albert ? ) . . i remember he had to 'pop the card out and back in again', and then issue the 'read sd card' command once more .... to get it to cooperate . . i am sure i remember that. did you watch the video ?
If you are "rebooting" into recovery, the sd card will often not mount. Rebooting into Android also seems to have this problem. Simply removing the card and putting it back in will solve it for Android. I'm not sure about clockworkmod. I generally just power off and then manually boot into recovery.
I popped and put back in the SD card and now CWM recognizes. However I'm still having issues.
If I load the ROM NT_stock_1.4.0_Ribbon_Root_v2 (from the lavero.burgos thread) after it says that the install is complete I see this.
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
If I load the 1.4.0 stock ROM CWMrestore_1_4_0__plus_NTV16gbV4_6 then as soon as it says Installing update... I get
Installation Aborted
Something is amiss with my CWM
Which model do you have?

It's the 16GB Nook Tablet
Well the ribbon rom shouldn't be seeing that error. You're installing the zip file correct? Maybe download it again. Try another rom like cm7 of cm9 and see what happens.
As for the cwm restore rom, that is not a flashable zip. You need to extract the downloaded file, place it at /clockworkmod/backup/ (on internal or external)and then restore it.

With the ribbon ROM I tried to take it to a place with free WiFi (since the error with not being able to get past the B&N registration due to not being able to connect to my WiFi) and get a different error. It sees the WiFi and when I click to registrator it bails with a message at the bottom that says "B-bind error." So I came home and again downloaded the other ROM (the 1.4.0 called CWMrestore_1_4_0__plus_NTV16gbV4_6) and still get the same error with that one. So I guess my next play is to try a third a third ROM but I'm not too confident that will work either. I've cleared the Dalvik cache. Should I also try clearing any other cache? I'm afraid I may clear out something I need and already kind of have myself in deep enough.
Last resort would be to reimage from an SD card but I feel like I'm so close and there must be something simple to get me over the hump.
How are you trying to install the cwm recovery rom?

The ROM was installed by putting the zip in the root of my SD card, going into the CWM menu and using the install zip from sdcard option. I also cleared out the Dalvik cache as rcommended.
The recovery wasn't from a ROM but rather from a backup I did before trying the ROM install. It didn't work for whatever reason.
I've since punted (reimaged via SD card, rerooted and backed up again). The ROM failed again. Same thing where I can't get past the B&N registration page because beacuse my WiFi doesn't connect (Connted, testing). I did notice this time a b-bind error.
The one thing different is that my backup was successful this time as I can restore to the rooted 1.4.0 mode (WiFi works). So I don't need to start from scratch again but still can't seem to get a ROM installed.

I have noticed that depending on what CWM you get it will try and mount /external_sd/ instead of /extsdcard/. The latest CWM touch from ROM manager has been failing loading external storage for me due to that.
However the last non touch I used (5.0.4 I think) worked perfectly for external storage.
As to why a reinstall of the same CWM fixed the issue I have no clue as I wouldn't think that would change it unless it was something residiual from a previous install of CWM.
I know you have fixed the issue, but this might help if it pops up again, check under the mount option and if it has the option to mount /external_sd/ or anything external that isn't extsdcard I am betting you won't be able to mount the galaxy external storage.
