If you are on MDK, I need really would appreciate one of you to run a script for me and upload it. Im trying to test whether we have the ability to use the sdcard to unbrick S4's like the Note 3 and Galaxy S3 people do. I only thought that this was worth doing since it works on the Note 3. If this works ill write up a guide on how to unbrick your phone without JTAG. Please upload the output. This would be very helpful to know whether we have the ability to unbrick using these means, also it would mean that we would be able to test bootloader unlock ideas without such a high risk of a brick.
Note: For this test you have to have a MDK phone. Later on we can test for ME7, etc.
Open terminal or use adb from a pc:
Edit: see below
If your sdcard is not located at /sdcard please edit the script to your needs, for instance on the s4 your external sdcard is located at /mnt/extSdCard so you could substitute that for /sdcard in the script above. Thanks

yes, but Im going to to edit the script because I don't want it to include any of your personal data, so to fix either go here and download the zip in the bottom of the OP (that creates the debrick.img for you) or you can use one of the modified scripts below (they both say the same thing btw, its just that I forget if terminal/adb uses bytes by default or megabytes). If you do decide to make this, pm the file.

I'll keep you guys updated. From what I hear this *should* work on Qualcomm variant S4's. So far, no dice, but I believe some of that is user error. Alot of this is writing the right partitions to right areas, with the right block sizes etc, etc, etc. Thanks guys.

Kind of, but not to the point of unbricking entirely. Im testing a alternative debrick method as we speak for MDK. If you want to test/need to test one out I can upload instructions and files. The debrick image has the gpt and partition info, it also contains the bootloaders for MDK.

If you are rooted you can just install galaxy s unlock by helroz and it has an option to just back up for /efs folder before you unlock. just select the backup option and don't do the unlock. No command line stuff required. The efs will be backed up to your phone storage.

Code:
su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs
The tar command with zcvf takes the input, in this case the efs folder and compresses it into a file in the output location, in this case on the internal sd card, while maintaining unix permissions, important for if you need to restore, this will make a small file.
Code:
su
cat /dev/block/mmcblk0p1 > /sdcard/efs/efs_dev-block-mmcblk0p1.img
Su gains root
Cat means catalog aka copy contents of what you point it at, in this case you are copying the whole partition where the efs folder sits.
In unix terms a folder can sit on any partition and be mounted into any point in the file system, just because a folder sits under "/" which is the root directory doesn't mean it's on the same partition, hard drive, or bit of flash memory.
We dump the whole partition so that if something goes wrong you can flash it back, i know heimdall which is an alternative flashing program can flash back different parts of the rom.
It's best to have both these backups to make sure and to give you different recovery options, flash via a program for the img or copying over the contents in the case of the tar file.
I hope this helps

To restore you can copy the contents of the tar file you made over the EFS folder, or if you ended up with an img flash it via Heimdall

The easiest way is to install cm9 alpha 0 (although it is an alpha, so be prepared for issues with the OS itself, plus remember that as an anti-profiteering measure it expires. read the full thread for more info....). When you use cyanoboot on emmc, you need to move the contents of boot.img and recovery.img so that they start at block 512. You can use dd or fastboot to put them on emmc...
See the original CyanoBoot thread as it talks about the above in a lot of detail, tho probably more than you need.
I read your post like five times I've flashed many Roms and did many things with phones and tablets. But I don't know what you mean by putting it at 512 or something I'm still a noob know how to flash move some things but when it comes to this I'm kind of lost

+1 to this, i'm trying to figuring out how to install it on emmc, in the post you get the idea of what you need to do but not how to do it, i mean what commands run,etc to install it. Say i want to test CM9 and want cyanoboot installed internally.
Could someone that has succesfully installed it internally (emmc) post proper instructions for this. TIA.

This may not be the exact answer you're looking for, but if you want to try it, just flash the newest CM9 (alpha 0.03) as it will install Cyanoboot to eMMC as well. I believe it's all contained in the CM9 boot.img.
There is no padding if you use flashing_boot.img on sdcard.
For emmc/internal, you need to pad flashing_boot_emmc.img to 512KB.
You have to pad flashing_boot_emmc.img correctly or else it can't find boot.img/recovery.img so you end in a bootloop.
dd if=/dev/zero of=flashing_boot_emmc.img bs=1 seek=524287 count=1
flashing_boot_emmc.img is then filled with zeros so the file size is 512KB. You then need to append boot.img or recovery.img to it.
cat flashing_boot_emmc.img boot.img > new_boot.img
Your new_boot.img can now be flash.
I haven't use cyanoboot, but bauwks 2ndboot method is the same except you need to pad it to 256KB.
You can gain cyanoboot by flashing my mmcblk0p2 i uploaded here, if you like

No Luck So Far
Been working for hours trying to figure this one out. Things to note is that now there are two mount points.
1) /mnt/media_rw/sdcard1 / sdcard0 (this has the actual /dev/block/vold/179:1 origin

I've been unsuccessful trying any of the old build.prop tweaks. Hopefully someone smarter will come along and bang this one out.

Hi
on kitkat, you should unpack your boot.img file, update the fstab.* files inside, repack it, and flash it.
The way the img file is built depends on your device manufacturer. I did it successfully on my mtk tablet with the tools I found in this forum.
I am pretty sure that unpack/pack tools exist for samsung as well (for example: http://forum.xda-developers.com/galaxy-s3/help/how-to-unpack-split-samsung-boot-img-t1810907 )

Before 4.4 I could do it by "Android Internal to External sdcard" app, but this app couldn't do the trick on 4.4 KitKat OS, so "Foldermount" could be a good solution for you. All this app does is make a image of your apps (that you want to) to sdcard. The real files are located in external sdcard and only the clone file ( of max few KB) will residue at internal sdcard. If you are a gamer, this will help you until the real solution arrives.
Good Luck.
There is real solution! Or at least it works for me.

Since Android 4.2 and the intro of multiusers there is a problem with bind folders across sdcards, making any attempt on mount bind folders as root would result in visible to root only.
Solution is to fool Android with temporary hijack debuggerd to create the mount binds for us. Thanks Chainfire for this workaround!
* Download both files and rename without .txt
* edit debuggerd.mnt to suit your needs (using any other dir then /emulated/legacy/ will result in read only if browsing folders from sdcard0)
* move debuggerd.mnt to /system/bin
* move mount.sh to any place with execute permissions
* execute mount.sh with any preferred method.

Thank You biopsin! Thank You Chainfire!
I'm including my files, but 'mount.sh' was not really changed in practical sense.
In case of 'debugger.mnt' it all depends on Your device. You need to check which block for You is internal and which external storage. Just 'mount' command should help.
You can also use it to mount only one folder - like 'obb', which will let You keep applications data on external card.
Just use "mount -o bind /storage/sdcard1/Android /obb /storage/sdcard0/Android/obb" command in debuggerd.mnt file.
You can also have different 'debuggerd.mnt' files (of course called somehow different - like 'debuggerd02.mnt') and different 'mount.sh' files which will let You mount different things whenever You like.
Enjoy!

hmm I guess 1M doesn't register on the phone... can you try again with this
Code:
su
dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1024 count=131072
the file size should be 128mb and then please zip/compress before upload. thanks
Here you go, I verified it was 128mb. It exceeds upload limit, so added to my dropbox.

Hey guys, worst part about samsung devices is always their EFS issues.. my samsung tool app has already gained support for SM-G900A, SM-G900F, SM-G900H, SM-G900T before root and custom roms are available, so first thing is first, root(when available) and backup EFS!
ive kept all downloads and discussion within the original thread here! - SAMSUNG TOOL APP HERE
this was made possible by leoaudio13 dumping his partition table!
I love u mate!

thats because nothing was accessible until after root, dumping system was easy, but any other directory/file on the device wasnt able to be read after until being rooted..
samsung didnt even include tar binary so I dumped over adb, then CF helped root and then we dumped raw images!

updated.
LTE devices have a QualcommChip, where everything is stored in the nvRAM, the EFS includes only files that have nothing but absolutely nothing to do with the IMEI.

I backed up my EFS to internal storage but cant find it don't see no /data/media/SamsungTool/ (using EFS file explorer) just want to save a copy to the PC. What's the exact name of the backed up file so i can use the search feature? cheers.

For full backup, which partitions do you recommend?
Galaxy S5 SM-900P Partition table
you can still simply create a copy right?
I have always had rooted phones and my SGS 5 is no exception, it got rooted using CFroot in the carpark immediately on picking it up.
I have therefore always simply made a copy of the efs folder on to the external sd card which is then synced to my dropbox.
However I have not really kept up to date with developments in these areas, so my question is nowadays is this still enough to ensure the safety of my device and it's ability to connect to my carrier. In the past when I have had issues after flashing roms and things simply deleting the /efs folder and copying the contents of my back up into it and rebooting has always been sufficient to get my carrier back up and running is this still the case with the international SGS5 qualcomm variant or do I need to consider other elements?
When will it work for SM-G900V? I just rooted my phone today and would like to use this for my backups. I just tried it by using EFS backup and now it's stuck on a triangle with an exclamation mark that says Please Wait. Ugh! Help...
