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?

go into recovery, wipe data/factory reset, flash cm7, flash gapps(google apps add on), reboot. if that still leads you to the same place, then redownload the rom, put it on your sd card, and try again.

You get this error because you are using i9023 version of Nexus S and you installed the stock version of Clockworkmod Recovery
You should install the Clockworkmod Custom Recovery from the Development Forums for the i9023.
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?

FRIED eMMC CHIP?
I've not tried any of these actions myself as I haven't yet experienced this issue, I'd recommend that great care should be taken before following any of the advice given, I suggest that you at least read and attempt to understand first, if you don't understand then create a new post detailing your own issue and experiences so that others can assist you and point you in the right direction.
The errors below don't necessarily mean that you've a fried eMMC chip, so don't panic just yet. Many users have experienced the exact errors below and have gone on to simply resolve the issue and use their devices again normally.

E:Can't mount /cache/recovery/command

BUT REMEMBER DONT REMOVE THE BATTERY DURING ALL THE PROCESS
sorry for my english
So, I have a Sprint HTC One (M7) that I tried to root following this guide:
http://www.xda-developers.com/how-to...-developer-tv/
Custom Recovery was flashed successfully (I tried both TWRP 2.5 and CWM 6.0.4.6), and I immediately got the following errors:
E:Can't mount /cache/recovery/command
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
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
I can't access /cache, in short. So, I tried to find my SD card, but my phone doesn't have a slot for one, and I couldn't figure out how to write to the virtual one inside the phone, so I selected "Install zip" option in CWM and passed SuperSU-v2.46.zip through sideload, and it failed when it couldn't access cache. I was then rather foolish, and tried to just flash a ROM from Android Revolution HD, found on this thread:
http://forum.xda-developers.com/show....php?t=2265618 (I used this particular ROM:Android_Revolution_HD-One_92.0_4a9d05.zip).
Again, I passed it using sideload because I don't have an SD card. The install formatted my partitions, then at 30% (when it began to copy files), it failed. Thus, I was left with an empty phone, but an unlocked bootloader. I tried a few more things, to no avail.
I think if I could figure out how to put something in the virtual SD inside, or somehow protect the install files from being overwritten during the install, that might get me there, since I'm guessing that it's formatting over the location of the installer/image. Also, I found that if I use the "Wipe /cache" from CWM, I don't get those access cache errors, but then I can't reboot into the recovery without flashing it again, so I'm guessing that it's saving it in the /cache partition. I use the command "fastboot flash recovery CWM_image.img" to put my recovery in there, which may be a part of the problem.
Anyway, any ideas or help would be nice. I know enough to be dangerous, but clearly not enough to get myself out of this mess. Any help would be appreciated, and at this point, it would just be nice to have any OS on my phone. All HTC recovery software fails because they require a locked bootloader, but my computer won't detect a phone with no OS and a locked bootloader...

Hello people of XDA developers,
One fine day, my nexus 5 started hanging up while booting. After the google Logo, the Marshmallow animation would show up and then it would hang and power off. I have no problem in doing a factory reset/wipe of my phone. But the only thing i want to save is my contacts. I have tried erasing and re-flashing system, cache, boot and boot-loader. Using ADB, flashing the cache always fails........ However, i have not touched userdata as i think it would affect the contacts too. I have even tried using different custom recoveries such as CWM, TWRP and even Philz Touch to use adb to pull my SD card files to my PC. Even flashing the system is not working now.... (atleast that's what my results were) .
Philz touch error messages....
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
E: Can't mount /cache/recovery/last_install
E: Can't open /cache/recovery/last_install
Driven to the point of desperation now........ Thanx a lot in advance... BTW, i'm a complete noob, so plz bear with me and my questions

Greetings,
Thank you for using XDA Assist. To get you the best possible help for your issue, I'm going to move this thread to your device's Q&A forum. Good luck!
Did you check your Google or gmail account to see if the contacts have been synced?
