Alright, so here is my explanation. I'm pretty experienced with flashing ROMS and what not just made a boneheaded mistake. So I've been running CM7 for awhile on my Vibrant. When the latest OFFICIAL CM7(05-19-11) came out it left me with no storage for applications. So I thought to myself, I'll just partition some of my External SD so I can. Well not using my head it partitioned the Internal SD, and now I'm in a bit of a pickle. When I tried to flash back to JFD was caught in a bootloop and had to ODIN Eugene's No Brick Froyo with Repartition unchecked and then ODIN JFD again. Well I've got my phone up and running again but when I try to go into ClockworkMod Recovery it gives me the MBR Checksum Error and now I can't flash any other ROMS. I've tried Formatting the Internal SD, but not helping. Any answers would be greatly appreciated.

Did you ever get a reply or a way to fix? I see throughout the forum that many have similar issues. Thanks!
bump would love to get an answer on this.
To fix this you need to erase the extra partitions you created on the internal sd card.
Use parted with adb to fix it, 100% fixable
parted rm 2
parted rm 3
Then odin to 2.1 with repartition checked
http://forum.xda-developers.com/showthread.php?t=534714
I will try it later this week, unfortunately can't right now. I hit the thanks button, and if I could hit it 100 more times I would! Hope this works...the guide is a little intimidating ;-)
I have tried for hours now to get this to work with no success. I have errors every step of the way, adb is not letting me do anything, and I have followed the directions to a T. Is there anyway of doing this?
Ultimately this will help a LOT of people, so if there is a way to fix this issue without adb, that is preferred. If not, then a detailed instruction from beginning to end would help (or video! . I am not a n00b when it comes to this, but I literally have tried everything through adb and cannot get to format my internal sd. I am thankful to be able to have stock on my phone for use. Thanks again!
Hi,
Sorry for the late reply..
adb is for pushing parted into phone sbin folder then chmod 755 then run parted from phone.
here is parted for you
http://www.multiupload.com/CA5NCRMBPC
adb push c:xxx/sbin
do it for all files in the parted.zip after you unzip it
su for become superuser
then
chmod 0755 /sbin/xxx for every file in parted.
cd /sbin then run parted
you will have this:
>(parted)
type print
>(parted)print ->enter
Now you will see 3 partitions
/system /data /swap
>(parted) rm 2
>(parted) rm 3
You cannot remove system
Then
>(parted)quit
exit
exit
run odin with repartition enabled! <-you need pit file
Enjoy and hit thanks button again lol
Regards
Edit: If this dont work you need cwm then format \system from cwm then re-run odin with repartitions enabled
Can't wait to try it (lol). Thanks I will update and let you know if this worked.
I am sad to say that nothing worked. I followed the instructions and did the rm steps, flashed stock via odin and it still had the error. formatted system through cwm, still the error. I am at a loss
Hi,
after you rm the partitions did you check "print" again?
Make sure they are removed
Dont get desperate i can help you more privately if you want just pm me you skype details, so we can fix this once and for all.
Regards
I didn't check it...sent pm.
This is what I am getting when I get into parted. Also to get into parted I have to type in
parted /dev/block/mmcblk0
If I just type in cd /sbin then parted it says the device is not found. So as you can see the picture shows only two partitions. Thoughts?

the problem is no one knows where the EFS folder is on Galaxy Ace
and also mounting and reading from /efs partition bricked phones/wiped IMEIs (basically corrupted partition) in many cases. there's been huge threads regarding /efs on cheaper galaxies.
You don't need to mount your efs partition
And if you don't know where efs is search for the nv_data.bin

Your phone has a lot off folders
That nv_data.bin must be somewhere or you don't have a IMEI

But have a "dangerous" stl5 partition.
So there's no way we could backup our IMEI? I saw people lost their IMEI after downgrading to froyo.. Warranty not going to cover it... =.=
There is maybe a way will tell later
Sent from my GT-I9100 using Tapatalk
I'm interested in this since my IMEI is unknown according to my phone after trying to unlock it...
Especially if there's a way to modify a backup to put my IMEI in it and flash it to my phone. But I don't know if it's possible.
Can somebody try this in terminal emulator or ADB
remember this could be dangerous
Code:
su
dd if=/dev/block/stl5 off=/sdcard/efs.rfs bs=4096
when all this succeeds without complications then you will find a file on your sd "efs.rfs"
Upload that file here so I can investegate it

this is exactly the way ppl corrupted their efs - even copying (dd command) somehow interacts with some other process/subsystem apparently accessing it the same time - then it's IMEI gone/brick. i'm not trying to be smart ass, just read quite a bit about it here on xda and try to warn others what it can bring.
Allright thanks for the info

So, what does this do?
Dump current kernel (and recovery on devices having a seperate one)
Flash kernel from /sdcard/zImage
Flash recovery from /sdcard/recovery.bin
Backup EFS
(as raw .IMG dump and as .TAR archive)
Check/Verify EFS backup (i.e. compare to "live" EFS)
Restore EFS from either .IMG or .TAR
Open stock update .TARs and flash from from it:
- Modem Firmware
- PARAM.LFS
- Kernel
Reboot device
- normally
- to recovery
- to download mode
*) When you check the EFS backup right after you made it, it should show a 100% match to the current phone's EFS.
However, after a reboot, the EFS *does* start to differ a bit - that seems to be normal, during my tests the EFS differed for 80bytes more after each reboot, my original EFS dump even differed by ~150k already

Hope you like it.
If anyone has more suggestions on what would need to be checked/verified during the check operation, do tell

For the .img and the .tar or only for one of them?
What does it say for "mount returned:"?
"nv_data.bin not found" means a bad/corrupted backup.
// EDIT
Just saw the screenshot.
Something went wrong making the raw .img dump (weird....).
But the .tar backup is OK (100% match to the phone's one).
Hmm.... gotta investigate the .img issue some more.
Check this;
Sent from my GT-I9100 using XDA App
OK, that helps a lot already.
The efs.img dump might be all fine and OK, it's actually a problem getting it mounted to "look into it".
Dug around some more and also found this:
Code:
2: system error (out of memory, cannot fork, no more loop devices)
"2" was the returncode you got during the check, fits with the verbose error message you get when trying the mount from a shell.
Cool, at least I know where to look, not exately sure why this happens, but we'll find out.
Maybe a busybox thing, maybe I'll bundle one with the app....
thanks for updating~~~

Well, in a way.
IIRC the shell command "cp" (to copy files) is not available on stock Samsung kernels, and the app just calls "cp" instead of (like for most of the other shell commands used by the app) using "busybox cp" to call/use the busybox applet of the command.
As said, I'll try, check and hopefully fix this later tonight and if all goes well will have an update ready by tomorrow
Published v1.23 with the above issue fixed
The update should show up on the market soon.

Greetings,
I happened to restore a nandroid backup i created but encountered an "md5 mismatch" error. Here is a solution that my geeky cousins handed me.
STEP 1: Open Terminal Emulator
Step 2: Use the following commands. (DON'T FORGET TO REPLACE "2012-04-17.10.09.36" WITH YOUR OWN BACKUP FOLDER NAME)
su
# mount -o remount rw /sdcard
#cd /sdcard/clockworkmod/backup/2012-04-17.10.09.36
#rm nandroid.md5
#md5sum *img > nandroid.md5
STEP 3: (This will create a new "nandroid.md5" file without ANY "md5 mismatch" errors.)
Reboot your phone and enter Recovery (Home+Power)
Restore.
Hope this helps,
UsmanJ
That was what I quoted much earlier in my newbie guide
Defy-ing all limits.
little clearance before i proceed :
1. for example i have a folder name : 2012-04-17.10.09.36
2. now i have to rename it something like XYZ so now 2012-04-17.10.09.36 will be XYZ
3. now i will do this :
su
# mount -o remount rw /sdcard
#cd /sdcard/clockworkmod/backup/XYZ
#rm nandroid .md5
#md5sum *img > nandroid.md5
4. thats all or did i do something wrong ?

Your 3rd screenshot, your proceeding fine, except that there should NOT be a space between nandroid and .md5. This causes Terminal Emulator to recognize the command to be applied on two different files.
It is supposed to be "#rm nandroid.md5"

Same here...thanks!

Thanks alot bro now i can give my phone to the customer care
I can confirm this procedure worked on my SGS2.
I had a backup that I decided to rename it to something more meaningful than 2012.09.12.... to jbrom a.k.a. jelly bean ROM and when I tried to restore from this backup Igot the MD5 error mismatch message.
This solution worked great on my JB SGS2...
I only had to use the backup on my SD card which was located on this path
/mnt/extSdCard/clockworkmod/backup/jbrom
I found out my backup did not have a nandroid.md5 file on the folder. Somehow it got deleted.
Thanks for this solution:good:
Thanks for this, this helped me restore my backup.
How to know if backup works?
So I have a question.
How do you actually know if a backup does actually works?
Because I sometimes read that when a back-up is bad itself it could brick your phone.
Or a file is missing and you still get nowhere.
And since there is a md5 mismatch error, I guess something went wrong.
It's my first back up ever and I can't seem to find a answer to this question.
I back it up with CWM (5.0.2). And have a Samsung s5830i.
When in the folder backup (sd/clockworkmod/backup) I see a folder with a date and time.
I assume that's where my back up is.
In this folder there are 4 files.
Cache.rfs 5.3kb
data.rfs 25.5kb
nandroid.md5 1kb
system.rfs 221.9kb
Are those files as big as it should be?
Some web sites says that it should be around 1 Gb.
And is there a file missing?
Thanks in advance.
Thanks.

I had the same problem, I followed every step and it worked like a charm
Thanks UsmanJ!!!
thx so much. i did follow and it work for me.
i have a question,
my problem is a bit different but not at all.
i did a nandroid back up of my hugoboss stock rom. when i tried to restore it, it says that there was an error to restore system because of rfs format.
then i discovered that the problem was because recovery format in ext4.
so i used cf-root app ( i can't remeber the real name) that reboots my ace is recovery and format system in rfs, but now when i tried to restore stock nandroid back up it says me the problem of md5 sum mistmatch.
now i can try this guide?? or my problem is another cause first it gave me the other error??
i will have some risks doing that?
thanks
EDIT:
i read ( i can't rember where) of another way to fix this problem. it says to open nandroid back up with an edit-test app and to modify some lines.
what metod is better for my problem??

Hi!
Story goes like this. I have here clone Samsung S4 that I wanted to update the software trough CWM. Unfortunately phone died at some point and now is dead. But, I made backup of the flash with MTKDroidTools and with SP flash tool... and here comes the problems... I can not flash backup back to phone because yaffs2 files are not good page/spare ratio. Thanks to members rua1 and Alex1948 now it is more clear how to change spare ratio on yaffs2 files. Unfortunately I'm not very good with Linux, last night I boot Mint 16 from USB stick and was trying to repair my files but without success.
So, my question is: is someone willing to repair my files in Linux (who understand Linux terminal better)?
Here are some details from phone

Hi!
First, thank you for your reply.
Yes , I did figure it out that my files are not OK. I was trying to make them manually in "yafey" for windows (software to create and edit yaffs2 images) but this software have to much bugs so one time it create system.img with full lib folder second time only half of lib files are there and also there is no option for spare ratio change.
So, MTKDroidTools did make my system backup in a folder on my PC but I can not make yaffs2 file from it because there is no software for windows that works fine (I don't use Linux). On Linux it is easy to do (at least for someone who understand Terminal commands).
So, I can send you my backuped system folder if you are willing to make yassf2 file from it (in Linux). Data and Cashe files I have create in yafey and thay are ok.
In yafey if I make new yaffs2 file and insert lib,etc,app,framework... it will not create all files in folders... and after that when I try to flash that created system.yaffs2.img I have error from BROM s_ft_readlen_not_page_aligment (4017) again problem with spare ratio.
I still have here my friends phone so if you have any idea what to do and how to do please tell. I made backup from my friends phone but same thing data,cache,system,secro files are not created correctly. I don't know why is this is it because of the MTKDroiTools or is it because of the phone?
Aaaaaaaaaarghh!!!!!
You wouldn't beleive what I just discover I just try to put my friends phone in recovery so I give a try to make backup.
NORMALY my friends phone don't want to go in recovery (just light on screen), so I have call my friend to ask him does he do something with phones recovery and he said YES i flash some recovery from net trough CWM and after that he can not go in the recovery.
CAN YOU BELEIVE HOW UNLUCKY I AM????????
If someone have any idea???
