[Q] E:Can't open CACHE:recovery/log

In recovery i get this error message: E:Can't open CACHE:recovery/log
Also,
I tried to install a zip from the sdcard and i get this: E:Can't mount SDCARD:update.zip
Anyone have any ideas.
I am running WinVista Ultimate x64
tried different recovery?
I don't know any other recovery method.
err what? lol
go to my guide and look at flashing custom recovery. See if problem persists.
move recovery log to sd and manually flash zip.

I have updated my signature, hopefully the rest of the info you need is there, if not let us know. Thanks
Use fastboot to flash new recovery. If you want to know how to this, check bortak's guide. He did not wrote because he was bored.
I managed to find a recovery.img from somewhere and i'm back in recovery mode. But I still have these errors i'm faced with.
E:Can't find MISC:
E:Can't mount CACHE:recovery/command
E:Can't find MISC:
E:Can't mount CACHE:recovery/log
E:Can't find MISC:
As soon as this is sorted i can then find out why i can't format or mount the system, i won't be able to re-install my rom otherwise.
Was it really necessary to create another thread with same problem?
Which recovery did you flash?
Please post information from your Hboot! You get there if you turn your phone off, and press and hold first volume down and then power button for a few seconds. It's a white screen with three androids at the bottom and the import information is top left.

[Q] Some Questions to Bricked a100

Hi guys, my friend had the iconia a100 and it was bricked, i read some post here in xda about the brick issue of iconia a100 but got some different encounter from this
i tried going to recovery and got these showing up:
Erasing cache before SD update...
SD update cmd: recovery -
update_package=SDCARD:update.zip
Booting kernel recovery image
and after that a Android Standing up shows up with a green orb on its stomach and after that a Dead Android lying down shows up,
and got this error also
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (no such file or directory)

Its bricked, cache is gone and its the first sign its happening, its the exact same signs as 99% of a100 users get when its bricked. The other 1% are battery related/user error/straight to APX mode.

It cant mount anything, there's a huge thread dedicated to this.
You can try whatever you wish, but its not likely to do much more then waste time.

You may want to also read the thread. Adb can't fix it. Flashing a ROM can't fix it. Its going to die. Quite a few of us have gone through it, familiarizing yourself with a device is a good idea before assuming a standard answer is correct.

M8 not able to Decrypt

Hi, I've recently encrypted my M8. After using it almost a Month I've to say that performance has decreased a lot.
I don't want the Encyption any more, but when I try to decrypt the phone going to "Settings/Storage/Phone Storage" Encyption option is grayed out.
Ok, so I tried getting wrong 30 times the password when it boots, but when it says that is going to perform the Factory Reset, suddenly stops and restarts whitout wiping the phone.
As well when I get into Hboot and select Factory Reset, and also using TWRP option to Factory reset the phone the next text appears on the log:
===================================================
Factory Reset Complete
Failed
E: Unable to mount storage.
E: Unable to mount data/media during GUI start up.
E: Resource type (font) failed to load
E: Resource type (font) failed to load

MTP Enabled
Formatting Cache using make_ext4fs function.
E: Unable to mount '/data'
Wiping Android Secure
Updating partition details...

Hello,
You have to have stock recovery before you are able to do a factory restore. If you know your CID you can download the correct recovery for your device and flash it.

He's not trying to do a restore, he's trying to do a reset, which you can most certainly do without a stock recovery.
He can also do a "factory restore" without a stock recovery by flashing a stock backup, which he can get from many threads here.

Do you have a nandroid from before you encrypted? Flashing that should solve the problem. You could also try flashing a new ROM with a full wipe.

I had latest TWRP and came across that same error and it's mentioned in other threads about that same version TWRP giving mentioned error.
Flashed 2.8.0.3 and never receive any errors

Ok, I have given a try twice.
I flashed "openrecovery-twrp-2.8.0.3-m8.img", first try was doing a Factory Reset from recovery and the second using my 30 password attempts wrong on the encryption screen and nothing different happened, same error.
I used this options as it was the easy way, but since it didn't work for me, I'll flash a Nandroid backup or StockRom.
I apologize I didn't reply before, I'll report any issue just in case someone goes through the same problem.
Thank you all.
Been developing a long time...not a debate..lol...and your right you wouldnt have that issue with "philz" as its cwm and not twrp....

You won't believe what the solution was...
1.- Download the latest TWRP available (openrecovery-twrp-2.8.1.0-m8.img).
2.-Enter to Recovery.
3.-Go to "Wipe->Format Data" and type "Yes"
4.-All Wiped! (Internal Storage)
This option was developed to remove encryption, I didn't know about that before.
But now you know as well.
Thank you again for your help!
