Help: EFS Not Mounting After Flash

I've been running CM7 for a month or so and I started having some stability problems. So I decided to try DarkyRom.
I did everything like normal (used heimdall).
Upon boot it had an error.
Failed to mount /efs while applying multi-csc.
I'm dead in the water. I tried to flash back to stock. I get an error and thrown into samsung recovery. I can reboot from that and I boot to the gui with no radio. Phone info says "Unknown" Hardware and Baseband Version.
No. I did not backup any EFS (news to me). I do have access to the same model phone, my son has one he just uses as a fancy MP3 player (no phone/data plan).
Is there anything I can do? I did use the ADB Shell and ran "mount" to see if the EFS was mounted. It was a negative...

Could this have something to do with the file system?
I don't have CWM working. I'm going to work on that. Right now I juast have Samsung Rec. Utils. The error that is in there is:
E:Can't mount /dev/block/mmcblk0p1 (Invalid argument)

First off,are you even on the right forum? Darky rom isn't built for this phone so it's not going to work.

Ugh...an unfortunate response. Yes...I'm on the right forum.

I did make a CWM backup from a couple weeks ago. Not sure if that helps.

Them why are you flashing roms from other forums/phones? Use odin and check repartition.

*hangs head* Admonishment accepted. I really don't know what I was thinking.
Here is my progress. I tried using Odin to just Re-partition. No go.
<ID:0/003> Can't open the specified file. (Line: 1455)
So then I downloaded stock EC10 (That was factory on my phone). I flashed that via Odin with "Success".
The same error as initially posted was on the phone. I rebooted from the stock recovery console and I was able to boot. 3g works. The hardware and baseband are now accurate. I'm getting a lot of force closes however. The twlauncher is constantly crashing.
So now the phone is semi-functional but there are still errors. (I was getting more forces than normal in CM7 that caused me to dive into this process in the first place).
I could be way off base but I'm thinking that possibly there is corruption (or wrong file system?) problems with the internal SD (I did format the External SD at the start of this).
I appreciate your help. Any suggestions from here?

Additional Note: Settings are not saved between reboots.

-Rooted
-Installed ROM Manager
-Installed CWM 3
-Reboot into Recovery Mode
No go. Same /dev/block/mmcblk0p1 error (installation aborted)
The 3e recovery also says:
"your storage not prepared yet, please use UI menu for format and reboot actions."
I tried both wipes. Errors.

Use the full odin restore package and make sure you use pit and pda files. Repartition must be checked. Wiping data might be a good idea as well.

I would odin the full mesmerize package EE19. http://forum.xda-developers.com/showthread.php?t=881064

That is what I have already done I believe. Followed instructions from:

If you've done that, then i'm at a loss. That usually is my solve-all solution... Sorry man.

Thank you much. Is it possible that I could have a faulty internal SD? I had suddenly started getting a lot of force closes in CM7. I guess I'm just wondering if I'm fighting two separate issues here. (My bonehead move vs. a real problem)
-MT

I think I'm FIXED!
I was finally (I don't know how) able to get Odin to Flash CWM 4 (The Blue one needed to install CM7).
I got ZERO errors in CWM. So I took the opportunity to clear caches, format data...I got destructive.
I then installed the CM7 Rom. -SUCCESS
Installed GAPPS - SUCCESS
I hope everything is OK at this point. I know CM7 is booting in about 20 seconds opposed to 5 minutes like it was before I decided to try to morph my phone into an I9000.
I actually saw the black screen with the little phone to PC icons at one point tonight. I think I came real close....
Thanks for your help!
PS: CONFIRMED mmcblk0p1 is mounted! (EFS, etc) PHEW!

I had this happen to me right after a Odin even did the rfs formatter tool exact same problems not saving settings upon reboot and it saying something along the lines of process.android.blah blah blah and double vibrate when booting before the fc anyhow I just reflashed miui to get cwm4 wiped everything reflashed cm7 no probs since

[Q] My CWM 3.x.x.x backup doesn't work : SGS2

Hi,
I checked through many threads to see if anyone had a similar problem but couldn't find anything unfortunately.
Background :
I was running a Lite'ning ROM on my Samsung Galaxy S2. You're probably familiar with this ROM, but for those who aren't it gets flashed with ODIN and comes rooted and pre-installed with CWM.
I forget which version of Lite'ning ROM it was, but I am fairly certain it was pre-1.5 as the bundled CWM was definitely version 3.x.x.x (later versions I found had 4.x.x.x and 5.x.x.x).
I wanted to try a version of GalnetMIUI for something a bit different and hadn't changed ROMs in quite some time, so I booted into CWM 3.x.x.x (maybe 3.0.0.2?) and did a backup to the internal SD. This came in at around 1.4 GB and comprised of 4 files :
cache.img
data.img
nandroid.md5
system.img
I copied these to my PC too, just in case they somehow got erased from my phone.
Once I'd done this, I then copied the new ROM .zip file (latest version of GalnetMIUI) to the root of the internal SD, booted the phone into CWM, wiped user data and Dalvik cache, then proceeded to install it.
The problem :
I can't get my apps or data back. I was under the false impression that my Google account was automatically backing this up for me, and would restore everything once logged in as it had in the past (factory resets etc.). So once this didn't happen, I tried using CWM to revert back to how things were before installing the new ROM but although the restore appears to work I end up with issues.
I've tried a number of different ROMs and they either get stuck in 'boot loops' or a black screen after running through the restore procedure. I've tried restoring just data via the 'Advanced' option but this doesn't help.
I was under the impression that I'd be able to fully restore the ROM backup if I needed to, and have the phone running exactly how it was prior to messing around. It would seem this is not the case.
In desperation I tried flashing every Lite'ning ROM from version 1.0 to 4.2, restoring my backup each time but as mentioned I always get boot issues.
Have I lost my data? I hope not, as I had 'To Do' lists and all sorts of things that would cause problems if they were not retrievable. I realise this is a lack of knowledge and foresight on my part. I'm thinking now that I should have run Titanium Backup prior to this, and not assumed that CWM was going to provide a complete solution.
Hope all this makes sense and if any of you have the time to read through and offer advice it would be greatly appreciated. I am currently running a very pretty and slick GalnetMIUI without any of my data!
Thanks in advance.

download cwm 2.5.x.x its better

Thanks for that, I'll give it a go tonight after work. Am I right in thinking that if it doesn't work I can extract the individual files and insert them manually to get my app data back?

OK, so after hours of searching I'm still no wiser as to how to install CWM 2.5.1.2
I found a zip file that was apparently version 2.5.1.2 but when I tried to install it from inside CWM 5.0.2.6 (included with GalnetMIUI) it sometimes gives an error, sometimes it reboots CWM and sometimes it simply says it has successfully installed (it lies). No matter what it says or does, it doesn't seem to actually replace version 5.0.2.6 with the older one and every time I do the three-finger boot it loads up the latest version like nothing changed.
I'm just so lost. All I want to do is restore my old backup, get my data back and move on. Please someone help me before I go insane from all this research!
[EDIT] In case any more information is needed, my exact procedure for installing version 2.5.1.2 of CWM went like this :
Download 2.5.1.2 zip file
Copy zip file to root folder on internal SD
Boot into CWM 5.0.2.6
Select "install zip from sdcard"
Select "choose zip from sdcard"
Navigate to 2.5.1.2 zip file, select and confirm

Can anyone help me at all?
In particular I'd like to know how I can downgrade to CWM 2.5.1.2 or similar in order to give [email protected]'s suggestion a go.
Failing that, if anyone has any suggestions whatsoever about how I can get my backup data restored it would be greatly appreciated. After spending some time with MIUI - in particular the Galnet ICS build - I have nothing but praise, but I really have to get my data back!

You should be able to downgrade through ROM manager. Go to "All Clockwork Mod Recoveries" and just flash one that is not 5.x.x. Any backup not made with version 5 will not work with the new version So if you can flash one that is version 2, 3 or 4 you should be good to go. If that doesn't work you can fastboot flash it. There are guides on how to do that.

Wait.....did you mount /system before installing the CWM zip ?

Sorry for the delayed reply, for some reason I didn't get an email notification that my thread had been updated.

For some reason, when I select "All ClockworkMod Recoveries" the only two options are 4.0.1.4 and v4.0.1.4. I'll have to look into "fastboot" flashing as I've never heard of that.
By the way, if I boot into CWM via ROM Manager the version that loads is 4.0.1.5, but if I perform the three-button combo when switching my device on I get version 5.0.2.6.

I didn't, is that something I should try?
Edit - Just tried this and at first it rebooted CWM and the version number hadn't changed. Doing this again yielded me the following error with no change in version number :
Code:
E:Error in /sdcard/CM V 2.5.1.2_update.zip
(Status 0)
Installation aborted.

I found out that I can extract the contents of my backed up .img files using unyaffs.exe.
Unless I'm doing something wrong, it would appear that my backup is corrupt somehow. When trying to extract data.img, it processes for a while and does bring back a lot of files but I also get the following :
Code:
read image file
: Bad file descriptor
read image file
: Bad file descriptor
data.img is around 1.2GB but the files I extract only amount to around 190MB.
It would appear that I don't have my contacts database in there which is annoying as for some reason there were quite a few that didn't get synced to Google's servers.

P1000 stuck at samsung logo and losing all settings

Hello everyone,
I have a Samsung P1000 GSM tablet which i purchased from Jeddah a few years ago.
Froyo started acting up and Samsung was not releasing any new firmware updates, and so i decided to root and move up to Gingerbread.
I installed 2.3.3 JPJPC and rooted and things were good.
After a while, i installed rom manager from the market, and installed the recovery for the wrong model due to ROM manager not having P1000 listed, which was a reckless move.
Since then, the TAB gets stuck on the samsung screen, and i can tell it is actually sort of trying over and over in an endless loop.
After a few reboots, it comes back, but losing all settings (home screen empty, phone book gone, SMSs gone), and it starts with the welcome wizard (language, packet data etc...).
The bootloader at that point was giving errors about not finding android_reboot and unable to load the mcc ...i'm sure you guys know them.
I read tons of threads about this, but no one actually mentioned that this problem is intermittent! And no definite solution...
Attempts:
I tried loading JPJPD (P1000JPJPD_P1000OJPJPE_P1000JXJP4_HOME.tar) via ODIN 1.7 using gt-p1000_mr_PIT and then dbdata, same thing.
I tried using P1_add_hidden.pit, same thing
I tried using GB-Stock-Safe-v5, same thing, moved again to JPJPD, same thing.
The interesting thing is even ODIN would FAIL the complete (write) then after 1 or 2 retries, it would work (same setup).
I also installed the recovery CF-Root-TAB7_XX_OXA_JQ1-v3.3-CWM3RFS, same thing.
At this stage the recovery works well, and so after each ODIN attempt I was wiping everything...
At this stage I'm trying to figure out if the P1000 is recyclable, organic, or waste!!!:crying:
Can anything be done to stabilize this TAB ?
Thank you,
Bassem
EDIT:
After posting, i entered recovery mode and found the errors i tried describing above have come back again:
"E:internal mmc : open fail
Internal MMC checksum verify failed
# MANUAL MODE#
-- Updating application...
E:failed to mount /preload (No such file or directory)
E:install_application_for_customer:can't mount /preload"
multi-CSC is ok
now when wiping /data:
"Formatting /data....
E:format_volume: rfs format failed on /dev/block/mmcblk0p2"
I am sure this will be fixed (which happed before) if i repeat the above steps, only to break again after a few reboots.

[Completed] SOLVED Galaxy Tab 10.1 help

Edit: SOLVED
Hoping someone can roughly point me in the right direction. I'm not very savvy in flashing new ROM's, but I had success with my phone recently, so I decided to try and update my tablet and it's not going so well. It's a Samsung Galaxy Tab 10.1, model GT-P7510MA, which I believe is wifi only. I started off by following the youtube tutorial: 0eAQzxwEVjY
I did *not* make a backup, so shame on me right off the bat, but at least now I've learned this lesson.
There is no OS, but TWRP v2.2.0 is installed and I'm able to boot into it just fine. I'm able to transfer/push files via command line on my windows machine, but I did find something that seemed odd, which is that the top level directory is not named "/sdcard", instead it's just "/". When I transfer files, I have to name the the path "/" for them to show up in the top level directory. If I use "/sdcard", it looks like they upload, but I have no idea where they go. Not sure if there's any significance there, but figured I'd mention it.
The problem is that I can't seem to install any OS. I've tried Nameless 4.4.4, Clockworkmod 10.1, and AOSP 6.0. They all fail the same way, I'll type out what it says below:
--Install /aosp-6.0-p4-20151211.zip ...
Finding update package...
E:unknown volume for path [/aosp-6.0-p4-20151211.zip]
E:Can't mount '/aosp-6.0-p4-20151211.zip'
* Verifying filesystems...
* Verifying partition sizes
Error flashing zip '/aosp-6.0-p4-20151211.zip'
Another strange thing is that when I tried the aosp-6.0-p4wifi, it said that this device was a p4, which I don't think is correct, but that's why I tried the p4 version. It errors just the same. I've also tried to update TWRP, but I'm not sure you can update TWRP from within TWRP? I've tried using the file "twrp-2.8.7.-picassowifi.zip" and it errors the same as the OS'.
Edit: It's been sitting here powered on for a bit and then went to the blue teamwin screen and would flash off every five seconds or so. I figured this was maybe a screensaver? Next it powered off and on restart, all the files I've uploaded are no longer visible.
Any guidance is much appreciated.
Final edit: Kind of embarrassing...all I needed to do to find the /sdcard directory was just scroll down a little through the folders on the left (I thought it was supopsed to be the top directory). I'm pretty sure the 7510 is a wifi only version, but for some reason, none of the wifi ROM's I've tried will work. It gives an error and says my device is a p4 and not a p4wifi. Anyway, neither of the wifi/p4 Marshmallow ROM's will work, but all I had to do was wipe cache/delvic/system (I did do this several times) and factory reset (had not done this before) and install Cyanogenmod for p4 with the recommended Google Apps and all is working well.

[Completed] (Nexus 5) Error 7, made multiple mistakes, "assert" fix isn't working

As I understand, my situation is fairly specific, and so I need to address a few points:
This is my first time rooting a phone- I've made several mistakes but managed, at this point, to avoid bricking my phone
I'm using a Nexus 5, and flashing the pwnphone system (Android Open Pwn Project)
I've followed all the standard steps (except one... see below) for unlocking, rooting, and using TWRP as my recovery
I've also successfully flashed AOPP once, although I made an error I couldn't fix during setup and needed to reinstall
To my stupidity, I forgot to make a Nandroid backup on both attempts
I've just used TWRP to wipe my phone's Dalvik/ART Cache, system, data, and cache, assuming I could reflash the same zip I used before
MD5 check is disabled
Zip validation is disabled
Okay, so let's get down to the heart of the issue now. My phone is sitting here, plugged into my computer, I have a command prompt running, and adb is working properly. I try to flash THE SAME ZIP file I used, just before, to start from a clean slate AOPP install, and now I'm recieving an Error: 7.
I looked up the fixes for this, and ran into a problem: I'm already using the most recent version of TWRP- and I just made an alternate AOPP.zip where I removed the asserts from /META-INF/com/google/android/update-script. I was hoping this would solve my problem, but it didn't.
Now, instead of getting an Error: 7, I'm getting an "invalid zip format" notice with very little other information.
Installing zip file '/sdcard/aoppfix.zip'
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
Invalid zip file format!
Error installing zip file '/sdcard/aoppfix.zip'
Updating partition details...
...done
Click to expand...
Click to collapse
I have no idea what to do at this point. In my earlier error, I failed to make a Nandroid backup file- and much to my dismay- I can't even find one someone has uploaded elsewhere which I could use to at least have a functioning phone to to boot into.
Can someone please help figure out what my next course of action is?

Hi and welcome to XDA Assist !
I`ve searching and I couldn`t find that rom on the Nexus 5 development forums so it`s hard to figure out what`s the problem
Your attempts to modify that script are courageous but I`m afraid that is more than a script issue
Try to flash a different rom with xda support and you`ll get more info and help , good luck !
