Can't mount /cache/recovery/

Hi there,
I used Cyanogenmod 1.1 beta for a while and while I was pretty happy about it, it did have some issues i wasn't very fond of. So I decided to to perform a nandroid restore of my stock rom and succeeded. My stock rom kept crashing when trying to use internet (synchronising, browsing etc). While messing a little with the settings (like no account syncing etc) my phone crashed and it went into an infinite bootloop. I went into recovery, did the neccesary wipes and performed a nandroid recovery to my Cyanogenmod again. It errored while doing so (can't remember exactly what the line was, but was something like unable to format...something).
Now when I boot into recovery it displays the following information:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
Any idea's? I know there is a lot to find about this on the internet and this forum but they're all guides from other devices and don't know if it would be wise to follow them
Help would be appreciated!

What happens when you attempt to enter RECOVERY and format CACHE?
Did you at any point in this boot loop process pull the battery?

Sorry, I'm afraid that I must be the bearer of bad news ....I believe that by pulling out the battery you have ruined the eMMC chip in the device, this appears to be a flaw or defect with a selection of recent HTC devices.
I believe that the only thing you can do is to return the device for warranty or to attempt to get the chip replaced.
Here are a selection of similar threads, within this forum which also cover this problem and I believe that you should be able to find others......

Thanks for your reply!
Too bad there is nothing to do about it. I'll just send it in for repair then.

having the same problem.. so should i try to wipe the cache and see what happens?

I fixed that by going into recovery and wiping the cache. It still says that it is unable to mount but re-flashing the ROM fixed all that.

I've tried that quite a few times, but it always failed to flash the rom. Did you get errors when flashing the rom?

What errors do you get when you're installing the ROM?
If you are still able to go into recovery then....
Do you have EXT4 recovery installed?
If not 1) Download this FILE which is EXT4 recovery 2) then copy it onto your SD card 3) enter recovery and flash the EXT4 ZIP file 4) Reboot Recovery
Then look at what format the existing CACHE partition is in?

OK i seem to be the next one with this Problem.
But for now it isn't a real problem, the following happended:
Used Hydrogen for some weeks, but wanted to try the new Virtuous Unity. So i did a backup of my apps with titanium, booted into recovery, flashed the Virtuous Rom, Install was complete and after that it says the known E: cant't mount ... and so on.
After that i pressed restart now in ext4 recovery and the Rom booted as it should. I restored my apps, everything is ok. But now i'm a little scared what will happen next
So is this the normal "way" it goes, or did i just have luck? I'm thinking about going back to s-on and stock, if this is possible.
Btw i didn't pull out the battery ever, cause i knew this could brick my ds, and i never had a bootloop or something like that.
Hope someone can give me some tips.
Cheers

The good news here is that you recovered from this problem and also that you didn't pull battery, so we can rule that out as being the cause in your case.
Between the Installation/flashing of the second ROM did you perform the necessary WIPES?
You may well have done, but, just in case, I'd always recommend that you take a full Nandroid backup of an existing system ROM before moving and flashing another (just to have a fall back position in case)?

@ EbiEre
I got scared after reading those lines too. Nothing to worry about. Just keep flashing roms as usual . Just a cache error. If you didnt pull out the battery, and if the rom booted, then everything is ok.

Yeah but I'm scared because I think it could brick "really".
I don't think it is sure that it only happen if i pull out the battery isn't it?
For now I'm back at the stock tom, it's OK but to be honest I love to root my phone and flash rims, and so maybe I will root again
Thx for your answers

Can only echo the comments of @.sh4d0w.
We all take a minor risk of bricking our devices with the majority of commands and flashes that we do.....but we still do them because that's half the fun...
Did you ever examine the format types ie EXT3/EXT4 of each partition using the EXT4 recovery?

[Q] [SOLVED] Galaxy Apollo (i5801) Failed Flash/Stuck at first screen

SOLVED
I've got a Samsung Galaxy Apollo.
During the Odin flash process it got stuck at ClockworkMod Recovery screen. Potentially stupidly, I rebooted the phone.
Now I'm stuck at the GT-I5801 Samsung screen, with occasional tunes (rising notes, tune cuts out at various points).
I can't seem to use the hardware buttons to get back into download mode or into clockwork recovery, I got into download mode last time by using adb reboot download.
Does anyone have any suggestions?
Thanks so much.

OK, So I Managed to persuade the phone to reflash, now I'm stuck once again in ClockworkMod Recovery, Odin is still running its timer.

Use the option reboot system now
Best would be to flash back to a stock rom, probably from your region
If it still wont boot, try wiping data in recovery

Reflash your phone again with Stock ROM without a boot-loader try it 2 -3 times and let us know. (use XXJPS ).
check this thread --> http://forum.xda-developers.com/showthread.php?t=1063940
If issue still remains --> goto the Samsung service station ASAP.

Solved.
Did a factory reset immediately after a flash in clockwork mod, phone booted successfully.

It is happenning if you had filesystem ext. So next time before flashing conversation your file system back

[Q] Urgent - Boot loop and unable to restore to stock.

Alright guys, I've got a question. I have my brothers nexus s that has had CM9 A11 on it and we decided to move to the latest CM9. Long story short, I am no longer able to boot the phone up, but can only access CWM Recovery and Bootloader/Fastboot mode. Trying to boot results in a bootloop. I need help getting this thing back to stock however I can. I've tried to flash recovery.img via fastboot but cannot get my computer to recognize the phone in order to do what I need. He would like his phone back ASAP and I hate to tell him its bricked for a few days. Thanks!

Download full OTA ROM from the link in my signature. Boot into CWM, mount USB storage, and transfer the file to SD card. Flash it. Done.
Just make sure you download the correct ROM for your phone model.

Video on that page will show you how to install drivers on a windows-based machine to recognise the phone for fastboot, and provide files to do so.
Also, can't you go into CWM --> mounts and storage --> mount usb storage (while plugged into the computer) then copy over any files you need, then flash through recovery.

I forgot to mention that I am getting this when trying to format cache:
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
E:Can't mount /cache/recovery/command
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
E:Can't mount /cache/recovery/log

E:Can't mount /cache/recovery/latest_log
E:Can't open /cache/recovery/latest_log
E:Can't find misc
E:failed to find "cache" partition to mount at "/cache"
I tried to install the OTA update like you said but got the following:
assert failed: write_raw_image("/tmp/boot.img".
"boot")
E:Error in /sdcard/(OTA file name here)
(status 7)
Installation aborted.
Maybe the internal SD card is bad? Any thoughts?

When you get the drivers installed, download the latest 5.0.2.0 CWM from here.

Alright, so I got fastboot to recognize the phone, but am having another problem. It gave me an error when I gave the command to flash the new CWM. I tried to install pdanet for the drivers, and the phone says at the bottom "FASTBOOT STATUS - FAILInvalid Command". I really think something has been corrupted, any ideas on how to fix it/restore it? Thanks for all the help guys.

Fastboot status is not a command.
Fastboot devices is the command you use to test if it sees the device . The serial number will show.

uh oh sounds like someone flashed brickROM V1

[Q] HELP- Nexus S bootloop, cache not mounting.

Hi, I was trying to install an ICS ROM on my Nexus S i9020a last night, and I must have messed something up. The ROM installed but it just hung on the google logo. So I went back into recovery (CWM 3.0.0.5) to restore my nandroid backup but I got:
E:format_volume: no MTD partition "boot"
Error while formatting BOOT : !
E:Failed to find "cache" partition to mount at " /cache"
E:Can't mount /cache/recovery/last_log
E:Can't mount /cache/recovery/last_log
E:Can't find misc
E:failed to find "cache" partiton to mount at " /cache"
I don't know much about what these things, but I imagine the seemingly missing cache is the problem. I cannot mount or format the cache either. I get similar errors. Flashing roms seems to 'work', but I still get the bootloop. Flashing img's does not work. "Installation aborted".
I have no idea what I can do to reverse this. At this point, I want to restore to stock. I hope I haven't done permanent damage. Can anyone please help me with this?

First try to upgrade to the latesy cwm. It had very much bugs fixed

Computer doesn't seem to recognize the phone in fastboot mode, can you link me to the a newer CWM zip so I can flash it in recovery?

[Q] Cant mount sdcard or flash factory images or update recovery. HELP!

I went into my recovery earlier and it came up with this:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/command
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
I tried rebooting my recovery and the same thing happened, only now it wont mount the sdcard.
I've tried to connect it to my computer to flash the factory images but for some reason my drivers aren't working, I tried to update them but it cant locate them even though they have been manually selected.
I cant mount it with the mount section in CWM and it wont let me factory reset (the recovery freezes).
The phone now wont boot (using carbon rom, but it has been working perfectly since I last updated it)
thanks for any help
