I dont think its necessary. But it would be safe to go ahead and use it. Ya know CYOA type of thing.

efs-backup won't work right since it's intended to be used from a BML kernel and it tries to mount /efs using the bml mount point. When CM7 release 11 comes out, you won't have to worry about this since the update.sh script will take care of the efs stuff for you. Erik is already using that script in one of his MTD roms, as long as all the roms get up to date with it, the efs-backup/restore zip files will become obsolete.

FB I used/followed the directions for the revenge rom to flash mokee and those directions still have us using the efs backup and restore. Is this updater.sh part of a new build?

Yup, I just haven't posted the new instructions in the wiki until Max gets R11 out, but as I said, Erik included that script in his build so you no longer need the efs zips with that specific rom.

[RECOVERY][MOD][Desire][02-Nov-2011] Clockwork 5.0.2.7.111102

First of all, this is not my work. I only compiled it.
This is the usual ClockworkMod recovery, compiled from the CM7 sources with additions/modifications by j_r0dd. What I've done is only to compile it for the HTC Desire. For details, check out the link to j_r0dd's original thread for the Nexus S.
The credits go to Koush for the recovery itself and to j_r0dd for the modifications.
j_r0dd said:
This is based on the latest CM7 source which I modified for myself. I take no credit for the recovery whatsoever, but I will take all the blame for my mods . We all know this is Koush's hard work. Just some things were driving me crazy personally. First was the confirmation menu. I really got sick of scrolling through all those "No"s just to flash something, so i changed it for me personally and just thought I would share. I also created a proper wipe menu. I got sick of some wipes in the main menu and the rest in the "advanced" menu. I made this more Amon_RA like. See the attached screenshot for my changes. That change has led to a few others by me. flash with fastboot or flash_image. THESE ARE NOT IN ROM MANAGER. Also if you have an issue with this take it up with me NOT Koush.

Bug fixes
Disclaimer
These recoveries are compiled using the latest commits from koush, j_r0dd and others. That means they haven't been thoroughly tested and might have minor/major issues. I take no responsibility for any damages this thing might cause, but most things should work as intended. If you want something guaranteed to work, I think you should stick with one of the older versions.

Well, like I said, I can't guarantee that it works, especially since I have no Desire to test it on. I've used j_r0dd's source which is based on Koush's source for the official CM7 3.2.0.0 ClockworkMod recovery. It might work, or it might not work. Testing it is up to each person.

Don't worry about it, I wasn't offended in any way. I'm wondering though if the USB bricks are caused by flashed (.img) recoveries. As I remember it, USB bricks were common with the earliest attempts to run recoveries by uploading the recovery binary to the phone's RAM while having to keep it plugged in to the computer.
well i know i got the usb bricks whilst restoring nandroids when my phone wasn't plugged in. that help in any way?

Maybe your misc partition got overwritten with garbage. In my opinion, nandroid shouldn't touch this partition. The USB brick issue is usually caused by a corrupt misc partition.

yeah i dont really know why it does, its easily fixable by reflashing the mtd0.img file generated from your cid and rom version though, its just a massive nuisance!

You should check your nandroid backup folder. If there's a misc.img or something like it, maybe you should move that file elsewhere. That way, nandroid shouldn't overwrite your misc (mtd0) partition. I'm only guessing that it does handle that partition.

It'll probably behave the same way, seeing as this one only changes the menus, I think.
Updated OP to version 4.0.0.0.
Thanks, please see http://forum.xda-developers.com/showpost.php?p=14598355&postcount=357 .
You should mod 3.1.0.1, no later CWM worked ok.

Yeah, I got that even on my Nexus S.. I'm just cloning & compiling. Got no idea how to downgrade to an earlier version. Limited programming skills.
I fixed the SD card mounting bug. Please re-download 4.0.0.0.
Still buggy. Each time you leave a file list, you'll need to "adb shell umount /sdcard" from your computer. Looking into it.
Added back the 3.2.0.0 version in the OP so you won't have the /sdcard mounting issue. Hopefully it can be resolved soon, so we can start using the 4.0.0.0 version. Sorry for the inconvenience.

[RECOVERY] CWM for the SK4G. Enjoy!

Special thanks goes out to everyone who tested for me.
I do not have the device, so I rely heavily on testers to report any bugs.
Here is CWM for the SK4G.
You will need to modify your stock recovery binary to be able to use CWM.
Kernel Devs can also compile CWM into their kernel by extracting the update.zip and building it into their initramfs.
To replace your stock recovery binary with the modified binary:
download this file
DEAD. USE BALI KERNEL
Exatract and take the recovery binary file inside of it and use root explorer or adb push the file to /system/bin.
DO NOT delete the current one there, or rename any files.
Just overwrite it.
I would however, recommend getting Android Commander from www.androidcommander.com It's a lot easier, and a lot more useful.
CWM Final
DEAD. USE BALI KERNEL
Place in the root of your SD.
You can now use Quick Boot from the market, or adb reboot recovery to boot into CWM
I have sent Koush the device tree to have the official update.zip supported within Rom Manager.
UNTESTED:
You can also take the contents from the update.zip and replace the contents that are in noobnl's recovery rerouter/root.
Again, I haven't tested that due to not having the device.

if we could get a stock kernel with just the ext4 patch so we would be able to run our system, data and cache on ext4 i'd be pleased enough . idk if anyone with this phone would be able to rebuild the kernel with that patch but if so our phones would easily be 3x faster
I also see the same problem. I didn't think to test backups. What was all changed from the working version to the current version? all that needed to be changed was the lun map and BOARD_USES_CUSTOM_KEYMAP

yes i tested the original one completely and everything worked, the new one you sent me i only tested the buttons and mapping which were fine . but it seems now the nand backup/restore has a problem.

not hard to do at all. unpack, add in ext4 mount options, repack, then flash kernel, and script to convert.

[RDU][CWM] BML to MTD Conversion Utility v0.1| [5/17]

The Goal: To create a CWM flash-able .zip that will convert a BML formatted phone to MTD without the need to be included in a rom, creating a standard and simplicity for end-users.
RDU
ROM DEVELOPERS UNITED
AS ONE
CWM BML to MTD Conversion Utility​Supported ROMs:
- Any BML Setup
So here's how it works:
This file will convert your phone's kernel and boot recovery to MTD. Afterwards, you will be able to flash an MTD rom.
ALWAYS make a backup of your data before flashing anything.
If you flash this over an already MTD rom, it will simply abort.
The Latest Version Here. After it finishes, your phone will be stuck in a loop. Pull the battery and 3-finger back into recovery to flash an MTD rom.
UPDATE: (--/--)
Further ideas or customizations from fellow rom developers welcome.

Please note, this is a test version.
It's based on a version I used myself, but being on MTD, I can't test it easily.
There are 3 current scenarios it could yield:
1. Nothing happens.
2. It works perfectly.
3. It works, but puts the phone into a bootloop. This is what the old version did to me... Pop the battery. Boot into recovery. Profit.
So this would theoretically convert a BML ROM to MTD on a person's phone. Sounds great.
As a note to all remember as always to back up before flashing ANYTHING.

Right now it should format your phone and prep it for a Rom. If it works properly, I'd like to rewrite it to convert and PRESERVE a BML Rom into an MTD Rom.

Yup. I need someone to confirm that it works properly. As I mentioned, I previously used a simpler version to convert myself to MTD and it worked, but it put me in a bootloop. I'm hoping to solve the bootloop so I can create a version to preserve a setup.

Well if you ran this and it put you in a boot loop, then it most likely worked properly since this would have formatted/converted your partition map to MTD. The BML rom would have either been erased or just unable to run due to the conversion.
Just a curious question here:
What would you need to do to actually convert an existing BML install to work on the MTD partition map?

Because formatting destroys the existing file structure (it doesn't actually erase files, just overwrites the data that maps out the locations of those files), everything would need to be copied to a temporary location before converting the original location to the new partition type. Then the temp data (backup) would need to be copied back to the original location using the new format.
It is not possible to just change the format while leaving the data in place - those warnings on every format command (in every computerized device - windows, mac, etc) were not a design decision, but a result of a design limitation. The backup/format/restore method is the only way.

He also said he was trying to solve the boot-loop problem, not a formatting problem. The clarification was not to assert that the formatting worked - the focus was on explaining the cause of the boot loop, to point out that there is no problem to be solved there because a BML kernel should boot loop when the rest of the partitions are freshly formatted MTD partitions.
The standard BML kernel can't read MTD, so the fact that those partitions are empty is irrelevant. Even if the partitions were converted without data loss (via a backup/convert/restore), the kernel would still need to be MTD-capable (so this by itself will not convert a BML rom to MTD)
Hopefully this clears up some of the confusion...

A kernel that supports MTD and copy all system, data and cache folder then paste it back after the conversion with the new kernel.

Yes he did. I too read his reply.
My response to Random was that since he's put in the bootloop, then it worked for him due to the lack of converting the rom over. Therefore my reply implied that testing more won't hurt anything at all and would be good protocol, but may not be needed since it worked for him given his output.

Ahh yea, I wasn't 100% sure if this was the case. Good breakdown though.
Doesn't seem to be working, I'll be uploading the version I use later on with directions.
I understand the theory, prepping a 100% BML setup for it's MTD future; just out of curiosity, Q: would there be a way to reverse this process so that if you arrive at your destination MTD ROM + change your mind, would it be possible to choose to convert an MTD ROM back to BML w/out having to ODIN (md5.tar + pit...........the way we do currently)?
BTW, am looking forward to testing your proposed conversion utility, just wondering.

All I know is that it'd need an mtd kernel. Also, maybe it could work like rfs to ext4 where it backs everything up then restores and flashes an mtd compatible kernel. Theoretically, that should work on samsung tw based roms.

Randomking, to fix the bootloop issue, try having it reboot recovery like the cm/miui mtd install scripts do (I think).

Not possible since BML is proprietary. Odin is the only way to get this top secret partition information on our phone.

I think its possible...if I knew more about conversions I would definatly look into it...I did however look at the updater.sh and it did give me an idea...
After looking at it this is what seems to be the process...(summarized)
Flashes boot.img then reboots, after reboot it then creates the mount points
Now what I'm thinking is this...if we edit the mtd parts to represent our old file system format...maybe that would work? Like switch put the mtd mounts with bml mounts...idk though...
That's just me brainstorming when its past midnight
But I'm positive its possible...just don't know the process

Process is as follows, correct me if I'm wrong JT:
Begin flash from CWM, which starts updater script and runs bml_to_mtd, setting mount points and such. Then formatting of all partitions except for maybe boot.
Once done, updater script has a "oneshot" flag so that flashing to MTD only need happen once. after mounts set and partitions formatted, reboot.
second run checks format and, if MTD, begins flash.
Without looking at the updater script file (or anything else in the conversion process for that matter), the above would be my best guestimate, as it's been a REALLY long time since I've had to script anything like this to be done. I've done custom Linux installs and scripted the formatting of partitions, but that was on hard drives that already had all their mount points set.
I think we need something like this...http://forum.xda-developers.com/showthread.php?t=1375272
Hope that guy can figure it out...if he can then all we would have to do is edit to match our device and our format (I think...correct me if I'm wrong)

Well, at least its easier now than it used to be. I remember having to set static memory locations (IE 0F0D3000-0F0D38AA), but this seems a whole lot easier since all you have to do is set partition sizes and mount points...

[Q] Resizing /efs partition, possible?

Hi, I have a t959v and I have been trying to restore my IMEI (that's because I was able to backup my /efs partition).
However, after I flash CM 10.1 for my device, my IMEI is gone, or has turned to 0000000.... or has turned to ASCII characters that I couldn't even read. I tried restoring my nv_data.bin file, done everything I could(googled and tried so many posts, I've lost count already.) and ended up with still, a corrupted/missing IMEI. Well after tinkering with my device, I've found out that the reason why my nv_data.bin (5.2 Mb) corrupts as I transfer it to the /efs partition--it's because my /efs partition is a little bit small, that's why my nv_data.bin ends up in an incompleted transfer state(corrupted file). From 5.2Mb, it falls to around 3-4Mb. No, it's not compressed or anything, it's cut-off, or "cropped" if it's the right term(which I doubt). Now, the my question is, is it possible to resize or grow my /efs partition? If yes, then how? First of all, thanks for spending some time in reading my post. Now, could anybody help me? or if it's such a pain to do, is there an alternative to CM 10.1 that has minimal glitches or bugs? 'Coz it's a pity if I couldn't upgrade from GB. The hardware of this phone is good enough, but the firmware is kinda frustrating(slow, freezes, and worst of all, GB), don't get me wrong, I don't hate GB but for the hardware of this phone, it's too good to just stay in GB. Thanks again!
Reflash back to gingerbread. That should restore your ieme number. Than try again.

Sure, but that doesn't answer the original question. Going back to BML (which was on Gingerbread, of course) will restore the original /efs partition. This is because all of the MTD installs do not overwrite the original BML /efs partition.
Now, the concerning issue is that the nv_data.bin shouldn't be getting any bigger then the original (I don't have my sgs4g on hand to verify), but what may have happened is yaffs2 partition options in the kernel may not be the same or formatting may have added more partition data to the filesystem layout that makes the available free space on the partition less. (does this paragraph not make sense? If so, ask and I'll go into more detail)
So, let me ask you to do a test.
WARNING!!! Make sure you backup the EFS partition while on GB before emptying the directory!
Backup EFS (do this from recovery with adb shell):
Code:
su -
mount /efs
mount /sdcard
cd /
tar cf /sdcard/efs-backup.tar /efs
Go back to stock GB. There are Cne-Clicks I made to do this. Root the install and post the output of:
Code:
su -
rm -rf /efs/* /efs/.*
df /efs
Restore EFS (again, from recovery, adb shell):
Code:
su -
mount /efs
mount /sdcard
cd /
tar xf /sdcard/efs-backup.tar
Next, do the same for cm-9.1.0.
After that, do the same with which ever cm-10 or 4.4.x kernel you're using.
Post all of the values here and lets debug that way. I'll bet you that the available free space and total size are DIFFERENT when the partition is empty.
You don't need to restore the EFS on MTD installs, but MAKE VERY SURE you restore the EFS on the BML (Gingerbread) install!!!
Maybe also try different CM10.x and 4.4.x kernels and see if there is a difference. For each test, note which kernel, which rom. Also for each test, flash back to Gingerbread (bml, from the oneclick) before flashing a new rom!
All the nv_data.bin files I have are 262.1kB.
The tar backups the installtion script creates for you should be 700kB or less.
It sounds like something went seriously wrong with the nv_data.bin file you are trying to restore, so I recommend you follow the advice @champ1919 gave you and go back to gingerbread an flash your ROM again.
After you flash make sure that the nv_data.bin file under /efs/root/afs/settings/nv_data.bin is exactly 262.1kB. If that's the case then save the efs backup the install script made for you in a safe place.
Mine from froyo are 256.0 KB for locked and 260 for unlocked., weird..

Interesting. I think all the ones I got were from phones built at around the same time since they have similar text in the nv_data files.
The locked/unlocked files should be the exact same file size every time. All the tends to change is a single 1 in the file becomes a 0 to unlock it.
I had stored them in Dropbox. I betcha one is from the vibrant I lost, but, I thought I deleted it so I would not goof. As soon as I can get to a PC, I'll dig into it somemore. I wonder who wrote that guide years a go on how to hexedit that file. I should give them another thanks.

thanks for the fast response bhundven and the rest...
i apologize for not being able to reply as soon as you posted.
going back... i tried reflashing to stock and backed up my efs... however, when i looked at how big it was as a tar(ive tried making an rfs then put it into a tar. this is from the commands cat /dev/block/stl3 > /sdcard/efs.rfs or something like that. im sure that code came from a post here in xda too.) its size is 6.2mb.
and also... i have the log files of my cm10.1 upgrade attempt. posting it in case it would help...
also tried reflashing to stock ang flashing slimkat but the problem persists.
thanks for giving your time in helping me. i will try to reply as soon as i can. thanks again.
Q: is t959v the same as vibrant? been googling but posts are really confusing.. XD

You kinda buggered up the Quoting of the post, kinda hard to follow. So I removed what I wrote and only quoted what you said so it makes sense. But even after that, I can't really make sense of what you are doing and why you can't follow my directions?!?

It's not confusing at all. SGH-T959V (VibrantPlus) is not the same as SGH-T959 (Vibrant). They are not compatible, and flashing roms between the two will lead to bricks. Make sure that under the battery it says: SGH-T959V
The only thing these two devices have in common is their original provider: T-Mobile
Otherwise, go to the right forum for your phone before following any directions in this forum.

Well, the reason why I was trying to flash CM10.1 is to upgrade from GB so if I were to reflash to GB then I would've defeated my purpose.
But, I did try that, and backed up my EFS so as to restore it later on after I have flashed CM10.1 but to no avail.

Im running the new slimkat with no issue. Fb's cm11 was just as good. I bounce between those and back to GB when I need tv out with no issues.

Im sorry for the messed up reply sir, and thanks again for your reply,
Just to confirm, my device is INDEED T959V.
I did the cat > /sdcard/efs.rfs bla bla bla thing in the hope to make an ODIN flashable "fix" in the hope of getting my IMEI and baseband fixed.
And, just as you said, it didn't work. I also tried erasing the /efs by erase_image then mkdir -p /efs and then cd /efs then tar xf /sdcard/efs.tar but that also produced a "cropped" nv_data.bin. Im sorry I can't try your directions as of now because I'm currently using my phone for work, however, I will do as you said as soon as I can free up my device.
Q: Do I need to take my backup before I flash a custom kernel? or is it ok if back it up while using a custom kernel?
Q: So T959V is VibrantPlus, is it the same as Samsung Galaxy S 4G?
Q: So if T959V is VibrantPlus, should I look for ROMs with the naming convention of <rom name>-vibrantplusmtd?

I have a T959V.
I tried the SlimKat and SlimSabre but I still got no IMEI even after manual restore. I also tried the CM11 and still have the same problem.
So, when you go back to gingerbread, your number is still hosed?

Well I've tried many posts about restoring nv_data.bin but none of them seems to work. I even tried to edit nv_data.bin by hex. That's how desperate I am to upgrade. XD
By hosed, you mean corrupted or invalid? I use OneClick Heimdall by sir bhundven I believe..
and to answer the question, I get my IMEI and baseband back everytime I flash the OneClick. It's when I try to upgrade to CM++ that I get the null baseband and IMEI.
and to clarify, I got that backup process directions from this post http://forum.xda-developers.com/showthread.php?t=859914

NO This is not the right place to look for help. Although the 'Galaxy S 4G' is a 'Galaxy S' based-device, it is VERY different from the i9000!!!
Do not use instructions from other device forums!!!
We have documented a lot for this phone in this device forum and on our wiki
As I mentioned before (in this thread) instructions on backing up your efs, and restoring it. Use my instructions and let us know in this thread if you have any problems!

1st, YES I got my IMEI and baseband back, but its a shame if I can't upgrade to CM++(because I don't get my IMEI and baseband after flashing meaning I can't use my phone for work.) because it's a cool rom, it has everything I'm looking for in a custom rom.
AND yeah, I wasn't aware that they were THAT different. Anyways, thanks for pointing that out.
Q: Is there an upgrade path or something that I need to do aside from the standard flashing procedure for these roms?
Bhundven's modified kernel should give you root. You could skip that step of using the oneclickroot and use the heimdall one click (of his kernel) and get cwm & root in one step. It's linked in the link he gave you.
After you install cwm, is that when you loose the imei number? Are you letting the phone fully boot? How were you getting cwm in order to flash the cm?

Sorry,
What I meant by OneClick is using Heimdall in flashing the purely stock GB rom. After that, I root using Framaroot(successful) then I flash a custom kernel(bhundven's blastoff...IMEI and baseband still ok after this), then I flash CM++ ROM, this is where it gets ugly--I lose my IMEI(null) and baseband(also null). and YES I let the phone fully boot, I even wait around 15mins and try to turn the radio on and off to see if I got my IMEI and baseband back, I also tried taking out the battery and letting the phone loose all it's power and then turning it on, again, to no avail. And to answer the other question, I get CWM through the blastoff kernel.
