Can't flash any ROM via CWM (status 7 / efs not mounted)

I was on Darkys ROM for some months without any flashing problems. Now i wanted to change from Darkys ROM 10.1 (Gingerbread 2.3.4) to Galnet MIUI. I had to downgrade to Froyo and then install the CWM zip in CWM. This was NOT succesful. It always says "Installation aborted (Status 7)". Then i tried to install CyanogenMod 7.1. Upgraded to Gingerbread Stock with CWM 3 and when i first flashed it via ODIN the phone first booted in the standart Android CWM display (dont know the name sry). The phone automatically formated cache etc. but then it showed me 2 times "/efs is not mounted". I was able to boot and to open CWM but ALWAYS when i want to install ANY CWM ROM it shows me the message with Status 7 ...
EDIT: The message when i try to install a zip via CWM:
--INSTALLING: SDCARD: update-cm-7.1.0-GalaxyS-signed.zip
Finding update package

How can i mount /efs again and make CWM ROM Flashing able again?
Thank you.

I am not a dev, but I suggest you do a fresh ODIN flash to stock rom or this SIMPLY HONEY ( its got odin version & hence very easy to install ) rom.

I already flashed several (stock) roms... still not working

The first thing you every do before flashing a rom is a nandroid backup.... use this to recover...
I hope to hear oh thanks i didn't remember about that, lol. But i do not expect it...
Do you have any backups, of the /efs maybe? If you do then find out how to put that back on..
An option would be to use adb to try fix it, first try the obvious and try mount the ef, if that doesn't work then tell me what files you have in the efs... and we'll try help you from there.
If you don't know hoe to use adb there is a pinned thread in the general forum, and I have made a there is a basic tutorial in a number of places either search here or google

[Q] Error in zip file when trying to flash ROMs from CWM

Hi,
I decided to try some JB ROMs. Coming from CM9, I wiped the phone, installed a new kernel and tried to flash CM10 (and later on, Tsunami). However, every time I try to flash a ROM I get the following error:
E:Error in /sdcard/[whatever i try to flash].zip
(Status 0)
Installation aborted.
I've tried Semaphore 2.2(s) and 2.3(s), as well as Devil kernel. It's unlikely the zip files are broken, as I downloaded them again from a different source. This issue doesn't apply to kernels, though - they flash fine. I even went back to stock briefly (via odin), but when I put in a JB kernel the issue persisted. I have plenty of space left in my phone so I doubt that's the cause.
Any ideas? I'd hate to have to run stock again.

If you are on ICS, try using an ICS kernel http://forum.xda-developers.com/showthread.php?t=1468795 most likely you have switched an incompatible CWM by flashing a wrong kernel for the upgrade

Hi, and thanks for the answer. After I tried flashing a compatible version of cwm, the phone somehow wiped my sdcard. After going to stock, reformatting the sdcard and rooting again I finally managed to go to cm10. Here's to hoping it'll hold until there's a more exciting phone on the horizon.

[Q] CM9 reinstall: make_ext4fs failed on /cache

Hi everybody, I'm quite scary about what I've done today with my tab.
1. I was running under CM 9.1 stable and everything was fine.
2. I backed up my data using ROM Manager and tried today a nightly build of CM 10 from get.cm. I installed it from CWM as written in Cyanogen wiki. Before install I was warned about partition format that wasn't the same as previsouly, and I was asked to choose the update.zip again to enable the ROM flashing to start. CM 10 booted correctly, and it ran very well at first. Then I chose to install Gapps through CWM, the same I did for CM 10.
3. After rebooting, I experienced a bug: the included keyboard kept crashing and was then unusable. I decided then to restore my backup of CM 9 through CWM.
4. I did not encounter any trouble restoring the backup to my old CM 9. But I had no radio, no IMEI, no baseband etc.. in "settings/about the device" and at this point I didn't know that this was because "/radio" wasn't mounted.
5. Now I don't remember what I exactly did but I try wiping caches, restoring again, reinstalling CM 9 stable, reinstalling CM 10 stable, restoring my backup again, flashing the Kernel using Hemsfall but what I remember is:
- I first had problems with /cache
- After that I had the "E:format_volume: "make_ext4fs failed on /cache" message
- My tab reboots if I try to install CM9 stable
- I tried to install a fresh firmware through http://forum.xda-developers.com/showthread.php?t=1133590 but I get stuck at hidden.fs
Now my tab can only boot to CWM or download mode, and whether I choose to flash to CM9 or CM10 I get the message:
assert failed: getprop("ro.product.device")== "galaxtab"...
E: Error in /sdcard/cm-10-nightly....zip
(Status 7)
Installation aborted
I don't know what to do now, and I'm quite desperate right now, please help me to get rid of that "make_ext4fs" error. I'm really afraid.:crying:

When you update to cm10, the mtd partition scheme changed to a new one. Nandroid restore won't work until the partition is made back to the same as when backup was taken.
To be able to run cm again, you need to restock to GB using Odin,
then flash overcome kernel to get cwm.
Only the kernel, not the ROM.
Then use cwm to install cm,
then restore from nandroid.
Follow my signature for overcome guide.
Get GB stock safe v5, the PDF guide, and the overcome kernel.

Thanks you very much, be blessed, it works perfectly using your solution. I felt really really bad, thank you so much!

you are welcome.
You may want to try CM10 again.
Make sure you flash gapps for cm10 only, not gapps for cm9 or cm10.1
It shouldn't be as unstable as you said.

[Q] Galaxy S Plus black screen, CWMrecovery says "can't mount...

I'm a noob I know and yes I watched the noob-video. But I need help! Cuz I'm too dump! So please help me
I wanted to update my Galaxy S Plus to the newest CM 10 (Beta 4) (before it was the Beta 3) over the CWM recovery it suddenly says
"symlinks failed"
"error in /sdcard/cm-10-20130324-invendor-beta4-ariesve.zip"
"(Status 7)"
"installation aborted"
so I looked to the CWM recovery and I saw that I don't have the latest version....okay I downloaded the latest one and installed it over the CWM recovery. The same error .... with friends. Now I got when I went into the CWM recovery: (after I tried to wipe data/factory reset or wipe cache)
"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"
I tried to restart the phone...black-screen after the samsung cyanogen mod screen.
Okay
So I tried to flash a older firmware "I9001XXKQ7_I9001DBTKP2_I9001XXKPK_HOME.tar.md5" with Odin. I restarted the phone...nope black screen. I installed the newest CWM recovery again and tried to flash again the CM 10. Black-screen. So I tried the old version of the CM which I had before (Beta 3) -> black-screen and still errors in the recovery mode.
I can still go into the download mode and the recovery mode. The charging symbol is not working when i connect it (just the battery but bot moving)
My device:
Samsung Galaxy S Plus
Provider: Vodafone IT
ROM: CM 10 (Beta 3) installed but not working
Kernel: Phenom 3.2 UV (updated after the symlinks failed error)
I hope some genius out there can help me
And sorry for my bad english...I don't use it often (Italy)

take your time...
what errors does the cwm 5.5.0.4 recovery shows without doing anything?
try to additionally mount system and data partition (see under <mount and storage>)
then click on wipe data/factory reset in the main menu

Hi everybody I'm new.
My situation is exactly the same, I did the same things, got the same problems... got stuck with no solutions yet if not to send it to samsung assistance.
Flashad many other android phones in the past and never had issues like this... it's a nightmare...

try to additionally mount system and data partition (see under <mount and storage>)
then click on wipe data/factory reset in the main menu
Click to expand...
Click to collapse
Without doing anything the recovery says nothing....just the normal main-screen.
After I mounted system and data I click on wipe data/factory...but then it doesn't do anything. It freezes after "Formatting /data..."
I flashed the FeaMod Recovery v.1.2. based on CWM v5.0.2.7

I already did that too but it didn't work...
I'm gonna go to the samsung assistance in the afternoon... :crying:

Well....Nothing is working...Anyone who could help me? ... Or better us..

If my guide is no use to you as its for i9000 : try this HERE
If that helps you in any way let me know.

I did this already... I flashed it with the newest stock-FW but it doesn't do anything...and the stock-recovery can't make a factory reset. It always freezes....

other things that could be worth a try:
try flashing different recoveries - not only feamod... also cwm,...
for me cwm5.5.0.4 works
look: our wiki-page -> un-brick
if all doesnt help you could try to reset all partitions

I tried already a few recoveries...like the CWM or the TeamWin... How can I reset them? Can you give me a link please? ^^

Flash BroodROM RC 5... flash this multiple times without touching any buttons like repartion etc..
After that, wipe system and data via the recovery provided in the ROM.
Then flash the newest stock FW from samsung..
This solved all my issues multiple times xD

thanks for the reply, but my phone is now finally brocked....it doesn't even start....and I don't have any idea what i can do now...

??
So, now Samsung, no Samsung Galaxy S Plus GT-I9001? No nothing. Not even the soft brick image (see wiki)

[Q] Continuous boot, assert failed troubles (Help)

So I posted a help thing about EFS a while back and didnt get to much help with that but i managed to figure things out. Now however
ive got myself into another predicament i cant seem to get out of.
So, from the start, i have a galaxy s3 (GT i-9305T) it was rooted, i still had the stock rom, but was running the beoffla kernal.
The idea was to download and install "JustArchi I9300XXUGML2 stock, deodexed and all the rest" then start finding
some nice themes. Ive got philz_touch_6.07.9-i9305.tar installed for my recovery.
This is where the trouble starts...
So first off i wipe the cache and the davik cache, go to install the rom then i get this: (ill go from installing update)
assert failed: write_raw_image (" /tmp/boot.img" , " /dev/block/mmcblk0p5" )
E: Error in /storage/sdcard1/Just archi........zip
(Status 7)
Installation aborted
Now i looked up a whole heap of pages to see if i could sort it out myself and i tried a few different things,
none of which have prevailed. First i tried to reflash an insecure boot image then try again, nup. I tried to
flash back to stock recovery and re format (No errors) then back to custom. Mounted /data and /system
and re formatted which worked with no error, still same error when flashing rom though. Also tried flashing
with different custom recovery, no luck there either.
There were a few other things i tried but i cant really remember what i did because
this has been a problem for a while now. Some of the pages i looked over for
information were:
http://www.droidforums.net/forum/android-hacks-help/26658-assert-failed-write_raw_image-tmp-boot-img.html

Can anybody at all shed some light on my situation,
or at least a place for me to start learning myself...

Hi.
If you downloaded the stock ROM from sammy mobile are these not meant to be installed via Odin?
There are a few post if you search for some of the pre rooted stock ROMs that you can flash with odin.
I would start from there.

The roms i downloaded from samsmobile were in .zip files, which im pretty
sure has to be flashed with one of the custom recoveries.
Thanks though

at first seems you tried to flash rom designed for i9300
then, you downloaded an ODIN image and you have to flash it by ODIN, no way you'd flash it over any recovery
to be more specific:
unzip the file I9305TDVBME2_I9305TTELBME1_TEL (STOCK).zip you downloaded, you should get a huge file with extension of .md5 or .tar
read in the forums how to use ODIN to flash firmware

and am going to check things out tommorrow.
