EDIT:
In my humble opinion, there's a new blade around, since all the sources for recoveries on english websites don't work with my 256mb "new" blade (jan 2012), while many people using older chinese blades from china unicom can use all the software found online.
flashing re regular cw with rom manager, adb won't work and give errors later shown in this post.
the only recovery i found that will actually work and let me install another rom is a recovery i found on a chinese forum.
downolad this recovery: http://dl.dbank.com/c0sw12amzu
chinese forum: http://bbs.anzhi.com/forum.php?mod=v...fromuid=423904
in that forum u can't see the download link because you have to log in and write a message in that topic in order to see the link.
to flash this recovery go to this thread, page 3 first post and follow the instructions from matt4321.
I am waiting for someone to try with "new blades" with the same problem as mine.
ORIGINAL POST:
hi everybody, i tried to look also in the forum with the search and i didn't find anything relevant...
i have the blade from china unicom, i rooted it and installed cw. everything was almost smooth (i downloaded the wrong z4root, but then i got it right).
when i tried to make a backup or anything else vis CW it shows me this:
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/last_log
E: can't open /cache/recovery/last_log
E: can't find misc
E: failed to find "cache" partition to mount at "/cache"
basically i can't do anything. i can't even make a factory reset.
what went wrong?
thanks to anybody that can help me.
Flash cwm using rom manager again
i tried but nothing... :/
thanks by the way.
Does anyone knows how to install CW via adb? i found how to do it here http://forum.xda-developers.com/showthread.php?t=852905 but i have no idea how to download the latest cw for my china uni blade.
thanks if anyone has some hints!
Are you sure you installed the right version of CWM according to your phone's GEN?
Sent from my Blade using XDA app
well, i guess so, my phone is gen2. i installed cw from rom manager, i just selected zte blade. i tried to reinstall cw, to reinstall rom manager, tried to dowload cw with wifi or data internet connection, same result as 1st post, or either like phone stuck on start screen when booting into cw (but the phone was working).
btw, i am using the latest cw.
i wonder what's wrong with my zte :/
Do not use CWM's latest verson

I guess that there's nothing wrong with your device. My Blade is similar to yours (256MB RAM) and the last version of CWM does not work: I even can't enter recovery mod with it. The solution is to use CWM version before the last one (5.0.1.0 I think).
You can easily install it via ROM Manager: Just go to the last option (CWM all versions and select the desired one).
[]'s
Ah, the Best rom so far to our stripped Blade in my opinion is Squadzone's CM7.2.0 RC 5.6
5.0.1.0 isn't working... could you please check which one you have on your blade?
btw thanks, i didn't see that option in ROM Manager!
i am trying with the 5.0.0.8, just in case... i hope it will work...
edit: no, it doesn't work... :/ i'll try with the previous one. with 5.0.0.8 i can't even boot in cw.
Anyone has a tip? it really doesn't work. i really have no idea how to do it via adb, if this could fix the problem.

I guess the only option for you is to try Amon RA recovery. I don't even know if it still exists. Check out the CM wiki regarding flashing. It might be there.

the problem is that i can't enter recovery mode (i can, but i can't use it) and i can't get the "green android" screen.
to my extent, i have no way to write anything via usb onto the phone. am i right?
i tried all of the cw versions, but all of them give me the same error i posted in the 1st post...
I think CWM can't find your root. Very weird issue. Will check and get back.

Try rooting the phone again! I had problems with my sisters blade when Z4root wouldn't perm root, only temp root (even if i pressed the perm root button).
Use zergRush to root again (or something similar) then flash CWM again through fastboot or adb
z4root actually works, apps that need SU enabled work also when i restart the phone.
zergrush doesn't work. everything seems fine but in the end the phone is not rooted.
plus, i can't use fastboot or adb since the recovery mode does not work, so i have to reinstall it from rom manager.
and yes, i tried to root it again, but with z4root, but nothing.
You should be able use adb with the phone on. Make sure USB debugging is enabled. Install drivers, use adb to reboot into bootloader, then flash cwm through there. Maybe there is a problem with the way rom manager is trying to flash cwm.

it could come from root access or you have made a bad manipulation, I have got a similar problem, my recovery has been deleted after have tried to flash one .
thanks matt, but I still can't do anything. adb command works from command line, but fastboot is not working.
the device is recognised when i type "adb devices" when rebooting in recovery, but any commands starting with fastboot give back an error "fastboot is not recognised as a command ..."
maybe it's the way i added fastboot. i found the fastboot.exe and put in the android-sdk\tools folder. even if i restart the pc it's still not recognised.
but if i go in the folder where fastboot.exe is it works, well, kinda, because "fastboot devices" gives me nothing. "fastboot \?" gives me the list of every option i can use, but i can't use them.
i guess it is like this because when i reboot the pc says there are no drivers for the phone. i actually tried to give him the drivers that come with the android sdk and the ones from zte, but both of them do not work. I guess that with the right drivers it will work, but i have no idea where to get them. am i right?
thanks for the patience.
i almost forgot, usb debug is enabled.
i found some drivers here: http://android.modaco.com/topic/319156-winxp7-zte-blade-drivers-and-adb/ and now it's recognised from the pc as "android bootloader interface", but fastboot is not working, it doesn't see the device. :/

Okay so it seems the issue is that fastboot won't work and there's some drivers issue!? I remember a while back when i had issues with getting fastboot to work with my ZTE blade, I can't remember where i got the drivers from but recently got my Xoom and the drivers installed from the device wouldn't work, so used koushs drivers for his tether app which worked, give those drivers a go but for ZTE of course, http://www.clockworkmod.com/tether/drivers
you could also try flashing CWM via adb which is what I used to do when I had issues with fastboot, i've got the instructions and commands saved on my computer if you want me to upload them? but then again a google search would probably produce the same results but i've used these before and know they work.
EDIT: also after rereading what you said and saying fastboot isn't recognized as a command (sorry if this is a dumb point) put when in the command prompt you are changing the directory to where the fastboot file is located right?!
as I understand, adb can't flash the recovery, only fastboot.
the drivers are working, windows xp recognise the phone both in recovery and in bootloader mode.
yes, i am running fastboot from the path fastboot.exe is located.
with google the only thing i get is rebooting via adb into bootloader and use fastboot...
so far no luck...
I think I may have my Nexus 7 (2012) in a badly bricked state.
I was running Android 4.3, unlocked and rooted with stock recovery. The tablet froze while using GMail. Pressing the home or back buttons just gave me a black screen with the buttons "highlighted" by circles. I waited several minutes and decided to just power off the tablet. When I looked over about a half hour later I saw that the tablet was frozen on the white Google screen. Two more reboots produced the same result.
I did some research and determined that it might be a good idea to try a cache wipe. I booted into the bootloader and selected Recovery. The tablet rebooted to an android on his back with a red triangle and the words "No command" underneath. Attempting to boot back into the bootloader (Power, Vol+, Vol-) produced the same results - red triangle and the words "No command". I could no longer boot into the bootloader. Powering off and powering on normally also takes me to "No command".
I discovered that I can press Power & Vol+ while in the "No command" state. Doing so produces the following text at the bottom of the screen:
E:Can't open /cache/recovery/log
E: Can't open /cache/recovery/last_log
E: Can't open /cache/recovery/last_install
E: failed closing /dev/block/platform/sdhci-tegra.3/by-name/MSC
(I/O error)
I get a menu at the top with the options to reboot, apply update from ADB, wipe data/factory reset and wipe cache. Attempting to wipe cache produces:
-- Wiping cache...
Formatting /cache..
Cache wipe complete.
E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/last_locale
After a few minutes I boot back to the red triangle android.
Attempting a factory reset produces:
--Wiping data...
Formating /data...
Formatting /cache...
Date wipe complete.
E:failed to mount /cache (Invalid argument)
E:can't mount /cache/recovery/log
E:Can't open /cache/recovery/log

E:can't mount /cache/recovery/last_log

E:failed to mount /cache (Invalid argument)
E: failed closing /dev/block/platform/sdhci-tegra.3/by-name/MSC
(I/O error)
E:failed to mount /cache (Invalid argument)
I've tried using the apply update from ADB option. I can use adb devices to see the serial number. Fastboot doesn't seem to respond and won't list the device. Flashing the factory 4.3 image (downloaded from Google and unzipped) using adb sideload uploads the image and then produces the error:
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Installation aborted.
...followed by all of the "cache mount / open errors shown previously"
Not sure what else to try. (I'm learning all of this as I go from reading posts on this site.) Is there a way to adb sideload the recovery partition as I suspect that it is corrupt?
Sorry to be so long winded. I figured that too much info was better than not enough. Any help would be greatly appreciated.
So you can still access the recovery menu? That surely means that your tablet isn't bricked and if you can access the recovery, then you too must be able to access the bootloader. Power off your tablet and try to boot into fastboot by using power and volume -, volume + isn't necessary. Are you sure you have also installed the drivers for fastboot mode? Then try to flash the factory images using the guide here

First - thanks for responding.
To answer your questions. No, I can't access the recovery menu. It doesn't matter how I boot - power button only, power button and vol-, vol+ or power, vol- only --- the device immediately boots to the android on his back with the red triangle. I don't get the normal "menu" where I can use the buttons to choose and select recovery mode. Sometimes there are the words "No command" under the android, sometimes there isn't. I can't get the tablet into fastboot mode.
When the device boots to the android + red triangle, the only thing I have been able to do is push power, Vol+ which gets me to the menu with
reboot system now
apply update from ADB
wipe date/factory reset
wipe cache partition
The "wipe" options fail with the text shown in my original post. If I select "apply update from ADB" it puts the device into ADB Sideload mode. (Not normal ADB mode.) My only option here is to ADB sideload images. I have tried sideloading the factory image. The image transferes, but it fails with a signature error and won't install. I have downloaded the image several times directly from google.
I have uninstalled and reinstalled the drivers a few times. I've used the article that you referenced, another article on this site and used the Wugs Nexus Root Toolkit to install the drivers. I know that my drivers were good originally as I used them to root the device.
Could the errors that I am seeing when I attempt the wipe options indicate a hardware issue? The device seems to be attempting to mount the cache and other partitions and can't.
Additional help is greatly appreciated. Thanks.

Your cache partition is corrupt. Because cache is corrupt, your N7 probably can't boot anything but recovery. Did your N7 turn off while you were wiping cache or something?

Looks to me as if your boot / system is not working or corrupt. But you are writing you boot always to the dead Android, that's the bootloader mode and from there you should be able to flash a new system by fastboot. As long as you can go to bootloader there is hope for your device unless some hardware defect prevents you from flashing the system images. Try to install the fastboot drivers for your OS and then try to flash the system images. Probably you need to unlock your bootloader first.

The tablet froze during normal operation. (Checking GMail.) I simply turned it off...or so I though. When I looked over about 30 minutes later it was stuck on the white "Google" screen. I was able to boot into the normal bootloader at this point. My thoughts were to then select stock recovery and just wipe the cache. It's been in the "red triangle" and "No command" since then.

The bootloader is unlocked. I was rooted with stock recovery. I have uninstalled and reinstalled drivers several times. I know for certain that the ADB drivers are installed. I don't have an easy way to confirm that the fastboot drivers are installed - but they should be.

Maybe sideloading the zip from the images package that contains boot, system and recovery?

I'm pretty sure that I've tried flashing the bootloader. When I try again (using adb sideload) I get the same signature verification failed message on the N7 that I did when attempting to sideload recovery images. I then get failed to mount cache messages.
I tried the flash-all.bat. Unfortunately that requires fastboot mode and the tablet won't go into fastboot mode. The batch file just sits waiting for the device to respond. Manually typing fastboot devices fails to list anything.
The only "response" that I seem to be able to get is when I put the tablet into sideload mode. I can type adb devices from a command prompt and get a reply with the serial number. The only other adb command that responds is adb sideload - which always reports signature failed on the tablet. Do you think this is a hardware issue?

I have no idea whether this is a hardware issue, could be, could not be. I remember a thread in which someone had a similar problem, only he had only access to fastboot mode. He eventually fixed it by running the flash-all.bat dozens of times, very strange. So how about sideloading the zip containing boot, recovery and system? I haven't read you tried that. And how about adb pushing flashable zip to your device and flash them in recovery? You can try all kinds of zip, ROMs, recoveries. They do need to be signed because you only have access to the stock recovery I guess.

I've tried sideloading the full factory image. That contains all of the boot, recovery and system images. Just like every other sideload that I've tried the file transfers from the PC. The tablet then reports that the signature verification fails. I've downloaded the factory image three times. I've done FC (file compare) from a command prompt and confirmed that none of the downloads are corrupt - they all match each other.
EDIT: I can't push a flashable zip as I can only adb sideload. I can't adb to just transfer a file. I also can't get into the recovery menu so I can't select a file to flash.
I agree that this is very strange. I've tried Googling the various "can't open / mount cache" message that I keep getting. I can't find anything about them. So this may be a very uncommon issue.
I appreciate your help. I'll keep trying different things. If anyone can think of anything else to try I would appreciate any advice. :fingers-crossed:

No problem. Just be persistent and try sideloading, and maybe adb pushing, the different kinds of images/.zips. Maybe you'll be lucky and magically succeed just like the other guy did. I guess this is everything I could advise you. Good luck.
Fastboot is working only when you are in bootloader mode, when you are in recovery or in "normal" operating mode only adb will work. The command is normally located in the sdk/platform-tools directory of the sdk and I suppose you have the latest android SDK installed.
Btw. for me it makes absolutely no sense that the tablet is booting to recovery directly, because the bootloader is loaded and started before, Only from there you are able to go to recovery, i.e. if recovery mode is working, bootloader must work, too.
To recover your system: go to bootloader mode and get fastboot running, then get the system image and extract all files and do the following:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
this should be sufficient. If you want to be sure you can also do
fastboot reboot recovery
and do a system wipe from there. And after that reboot into your system. Good luck!
@Remcotjuuh: it's better to use fastboot instead of adb, because you are one level below, i.e. if your recovery is not working correctly, adb will fail while fastboot does not depend on a working adb process.

i'm experiencing a similar problem with my phone. i rooted my phone today (using http://forum.xda-developers.com/showthread.php?t=2327473) and it was running fine, but i installed an application from the play store called [Root] Developer tools to allow me to load up recovery boot. i gave it permission but when i tried turning my phone on it just stays blank. ive tried the hard reset (up+power button) but all that happens is my phone vibrates 3 times and a green light flashes. please help
I have an LG G2 D800 with Cyanogenmod on it right now, and Clockwork Mod for my recovery. When booting into CWM, it gives me these 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
Also, when in the OS (in Cyanodenmod), when I plug it in, it won't let me drag any files onto it. The Google Play Store keeps on crashing too. What I want to do is just flash a new recovery, then wipe away CM and start it again. It's kind of hard right now though because I have no idea how I can get the files on my phone to do this, any help will be appreciated.
Bump :/

Yeah I tried both methods. Does this have anything to do with it? When I type in 'adb devices', I see my phone, but when I'm in adb shell, when I type in 'adb devices', it doesn't find anything.
EDIT: I found out I was able to install goomanager onto my phone, looks like I'll try that method instead
EDIT again: Looks like goomanager can't find the recovery to install on my phone, and I've tried installing both flashify and rashr, but it won't let me, ugh this is such a pain, I thought I was close
Is your "usb debuging" on?under developpement setting?
i found an automated script for adb http://forum.xda-developers.com/showthread.php?t=2472223
Adb should work
If not ,and if any apk can flash your recovery, u have to back to full stock
http://forum.xda-developers.com/showthread.php?t=2432476.
Then re root,reflash recovery etc....
How did u flash your strange recovery?do same but with twrp.img or a philz_touch.img
Look for thread about both, there is some 'how to install'.
I hope to be clear my language isnt english.

Thank you so much, the BAT file worked! But now I still have the same problems I was having with CWM, as in that my cache won't wipe, and my USB won't mount either.
EDIT: Nvm, wiping the cache in TWRP fixed it, I think I can figure out what to do from here on out, THANK YOU SO MUCH THOUGH
you are welcome
Recently I had an update from ASUS and at that time I had root on my device...So I guess my phone got brick due to updating while having a rooted device...I have tried all the steps of flashing via adb..Did "fastboot flash boot boot.img" , "fastboot flash recovery recovery.img"...All goes well...
Now the problem is when I get into bootloader(Power + vol up)/recovery/apply update from ADB from my device and on my PC "adb sideload filename.zip" it just does nothing...My cmd just waits and same goes to my device all it is written are
E:Can't open /tmp/update-script.log
Now send the package you want to apply
to the device with adb sideload(filename)"...
EDIT-"adb devices" doesn't recognize my device only "fastboot devices" does
I hope someone could help or maybe lead me to a post which has the same problem...Or maybe I need to send my phone to Asus Service Center for this issue...My bet now if this doesn't works I would try to flash some custom ROM maybe
First step backup u r data by twrp custome recovery..then go to link
www.google.co.in/url?q=http://www.w...ggOMAE&usg=AFQjCNHyTiR4lWYSzNkTaJO83PBJIf9Buw
U r problem will solved
NOTE: U MUST RETURN TO U R STOCK ROM THEN APLLY KITKAT VER 2.20.40.53 THEN LOLLIPOP 3.20.40.52 THEN GO 30.20.40.78...
Same problem with the op. i'll follow the steps u give in the link but it still failed. its says (E: Can't mount /cache/recovery/log), (E: Can't open /cache/recovery/log), (E: failed to mount /cache), and it keeps repeating for (/cache/recovery/last_log), (/cache/recovery/last_insta). So, how do i fix it? anybody knows?

Can't flash via TWRP, "failed mount system", twrp sideload not working either.. stuck
I need my phone for work tomorrow so any help would be greatly appreciated.
I'm on TWRP 3.2.3-1 and was using the latest stock oreo rom from here: https://forum.xda-developers.com/g5...o-twrp-flashable-stock-builds-coming-t3830482
My phone suddenly didn't have a reception today, after rebooting I regained reception but couldn't make calls. I rebooted to recovery and tried to dirty flash the same stock twrp flashable oreo rom that I was using and it failed. Apparently the OS got corrupted. I tried repeatedly to flash the ROM and then noticed I was getting an error : failed to mount system , invalid argument. I couldn't mount system via the Mount tab in TWRP and I couldn't find anything helpful to resolve this error.
I did some more research downloaded the fastboot flashable ROM from here : https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-fastboot-flash-stock-oreo-t3848433 and tried to flash the rom via adb using adb sideload in twrp but twrp doesn't seem to load that function correctly. In the elevated command prompt in the adb directory I type adb sideload filename.zip and it just freezes up my PC. My device does show up with the adb devices command and shows " *Serial Number* RECOVERY ".
I don't understand what to do with the instructions in the fastboot flash stock thread I posted above and I'm at the limit of my knowledge. No idea how to proceed... any help is greatly appreciated.
I tried extracting the xml.zip into the adb folder and rebooted to bootloader/AP Fastboot Flash Mode and was going to try the commands in the fastboot Rom thread but my device only shows up in adb devices when I load twrp. uhhhhgggghhhhhh guess I'll have to buy a backup phone tomorrow while I try to get this one working
Holy hell.... I didn't realize since I was in the fastboot/bootloader I had to use "fastboot devices" command to see the device. Tried that and saw the device listed, so I created a .bat file using the commands in the fastboot roms thread above and I have a functional device again. Whohoooooo!
Did you try to format /System/ as EXT4?
