Need help saving my phone - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

Can someone with rooted stock OK3 (and OK3 bootloaders) please do the following for me?
-busybox dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img bs=1024 count=81920
-alternatively you can run this file in recovery which will dump the necessary files to /sdcard/Unbrick_files/: https://androidfilehost.com/?fid= 23578570567721355
-Upload the unbrick.img and send it to me
here are the guides that I am following (which have some precedent for working with SGS5):

I recently bricked my phone by accidentally flashing a BOD5 bootloader over a rooted OK3 (and OK3 bootloader) system. This obviously led to a hard brick, and I'm trying to see if I can fix it. Thanks.

I can't confirm or deny if the debrick procedure works on the S5, but I made a debrick.img just in case. I'm on the BOD5 bootloader, so my debrick.img won't help you.
I do have helpful information to add, though. I'm not sure where the busybox part came from, but the path you posted is wrong for the S5. The internal storage is sdcard0, and external storage is extSdCard. The fist command needs to be su, and the second command needs to be:
dd if=/dev/block/mmcblk0 of=/storage/sdcard0/debrick.img bs=1024 count=131072 for internal storage.
dd if=/dev/block/mmcblk0 of=/storage/extSdCard/debrick.img bs=1024 count=131072 for external storage.

jrkruse helped me out a lot and I was able to get my hands on an OK3 unbrick.img. IT WORKS. You're right about me posting the wrong code. The file that he used to get me the unbrick.img included the following code:
#!/sbin/sh
mkdir -p /external_sd/Unbrick_Files/;
dd if=/dev/block/mmcblk0 of=/external_sd/Unbrick_Files/200MB.img bs=4096 count=50000;
busybox gzip /external_sd/Unbrick_Files/*;
mv /external_sd/Unbrick_Files/200MB.img.gz /external_sd/Unbrick_Files/Unbrick_IMG.gz;
chmod -R 777 /external_sd/Unbrick_Files
the file is available here:

you have linked the unbrick-creator.zip rather than the BOK3 unbrick.img

I am almost in the same situation as you. Can you please write the steps and the link for the BOK3.img ?

I think this is the correct link to the BOK3 unbrick img. You'll have to scroll down to the mediafire link
http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370/page11
Flash the file using win32diskimager.exe onto a microSD and boot into download mode.
Hope that works.
Also, if anyone has a rooted OG5, I would really appreciate an OG5 debrick.img!

Does booting from the SD card work on the S5? I bricked my S5 a few months back and had to get a replacement. It would have been nice to know that it would boot from SD.

Yes it does work, I can personally confirm it.

That's great!!! I'm assuming you were on the BOE1 bootloader, right?

Dammit sorry I should've thanked you personally. You pretty much were the direct reason I was able to unbrick. I know jkruse thanked you for the file but I probably also should have posted because the file was for me...

Here is your "knew how"... jejeje
You have to ROOT your A500 first... then use terminal emulator and type SU (this will give it Super User Access) then use the following commands:
dd if=/dev/block/mmcblk0p3 of=/sdcard/system.img
dd if=/dev/block/mmcblk0p6 of=/sdcard/flexrom.img
This will give you the actual system image (first command)
Second command gives you the partition where the update information is located.
Let me know if you need help rooting, its really easy, just remember to have your tablet in PORTRAIT not landscape or Gingerbreak will FORCE CLOSE!!!
Hope this helps... jejeje
I got a replacement A500 from JB HiFi. I will update to Acer_A500_1.139.04_COM_GEN1 then create a system.img.
This would be much appreciated! I'm in Australia, and having some issues too. Thanks again.

I'm at work today. Will hopefully get the system.img uploaded this evening, should take ~2 hours being 600MB and all. :-(
I'm not sure if the flexrom.img is needed though.

i know that it may sound like a dumb question but i have not got a clue.
I only rooted my a500 to be able to install apps to sd and that was a dissapointing move otherwise i think i may keep it stock from now on

You should be able to just copy the image onto your A500 and run the following as root: dd if=/dev/block/system-1.139.04.img of=/sdcard/mmcblk0p3
Be careful though, I honestly haven't tested the image but it should be fine.

so that means use command line and copy image onto SD card?
Sounds simple enough just gotta wait for 8 hours for download
Than again juzman very helpfull

I used the fsum utility on Windows and believe I created an MD5 checksum: 3A0AF183D5E582CBEA1D1F6BC7A61EA6
Will we need the flexrom as well when flashing this system image?
Also, this thread contains some original kernel modules: http://forum.xda-developers.com/showpost.php?p=13974214&postcount=62
Will the modules linked there be compatible with this current AU system image in the event of gps/wifi issues?

I used Better Terminal Emulator (with the extensions installed). Make sure after installing the extensions (after the prompt) to go into options, select root by default, then type exit (or CTRL-D) to close the terminal so it reinitializes with all the extensions (the icon on the taskbar must be gone). Afterwards do your stuff. After flashing the system.img the tablet might reboot (show the android boot logo) and cycle. Just power down holding the button long enough, and power back on, then flash the other img.
Hi Me again
dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
I did the above thingy and it just extracted mmcblk0p3 into sdcard
How do i install it ??
i cant just run it so i presume there is some kind of command or something in terminal?
Is it possible to get the flexrom too?
Thanks

update.zip files

Hey Guys,
From my understanding of how the update works, the easiest thing to do is update your device with the update.zip file that coincides with your kernel version if you have left your tab as stock. Is it a possibility to post our update files and list the coinciding kernel so those of us who have left our tab as stock and arnt comfortable in adb can update easily?
Personally, I am looking for the update file for the g9b3ce2b Kernel and build # acer_a500_1.104.02_com_gen1.
Suggestions or help would be appreciated.
Im still on 1.105.01_EMEA_GEN3 (!!!!)
Netherlands (bought 20-05 2011)
I hope i ever get an update (registred and all)
Especially with the Honycomb 3.1 update that is comming.
I hope it wil be possible to also get that update, without autoupdate,
because im beginning to lose faith in that one.
i havent seen any EMEA GEN3 updates yet on XDA.

Hi Chaz36,
I have seen, that you have the same build as my tablet has(1.105.01_EMEA_GEN3).
Sry about my bad english
I am looking for the /system/app/email.apk and the email.odex I deleted by mistake. I've looked around on this page, also found apk's, but the checksum is always wrong, and therefore also fails the update.
Would it be possible, if you have root, to upload these two files somewhere?
Many thx in advance

we in russia need only 1.105.01 images (boot.img system.img and flexroom.img)
Ive made those 1.105.01 imgs, and backed them up.
However, i have put the above (1.105.01 to 1.141) update.zip on de ext SDcard,
when i try to run it (pow off => on + vol down), it reads some quick dos-ish text, and then the droid stands there with the danger triangle.
maybe i did something wrong?

EFS IMEI Backup?

I have root my S4 and will make a backup from efs/imei but EFS Professional not working with the S4. How can i backup efs?
is it so hard to get a copy of ur EFS folder to safe place ?
You can use TWRP recovery to get a EFS backup

You can back up a whole partition with Terminal Emulator from Play Store.
This is example made for I9505 ONLY!!!!
For I9500 use mmcblk0p3 and efs.img instead!!!
Download it , and run it, then type:
Code:
su
dd if=/dev/block/mmcblk0p10 of=/mnt/sdcard/efs.img.ext4
and it will dump whole partition into one file efs.img.ext4 on your internal SD card
or
Code:
su
dd if=/dev/block/mmcblk0p10 of=/mnt/extSdCard/efs.img.ext4
to save it on external SD.
If something goes wrong and you need to restore it:
Code:
su
dd if=/mnt/sdcard/efs.img.ext4 of=/dev/block/mmcblk0p10
or
Code:
su
dd if=/mnt/extSdCard/efs.img.ext4 of=/dev/block/mmcblk0p10
Keep it safe and enjoy

With all respect to your post, I would like to warn people that this is not working for all the models/devices. Although it might look fine when executing the commands, it might not have made a backup of EFS, but of something else... What I know for sure is that it will not work for atleast the international i9505-model of the S4, as the partition layout is different.
In my post below, more details are given on this partition id.
http://forum.xda-developers.com/showthread.php?t=2276599
While executing your commands does not affect the device, it does not always give the people a backup they expect it to be, depending on their device/model. In my case you are able to verify which 'mmcblk' is actually efs on your device. It also gives a TAR backup as option.

The best thing is to check it with the developer. I do not know what file has been created, although I expect it to be a raw copy using dd. The best thing is to do it manually. Or by the instructions given by djembey, or by the more detailed step-by-step instructions in the thread of my previous post here.
Hey, I managed to backup the EFS folder. Is there any way to modify the backup file and restore it after the modification? I want to change the IMEI number but unfortunately I have no box / cables available to do so. There must be a solution?! I am currently living in Turkey and they restrict western mobile phone usage for foreign people.
thanks a lot

SDCARD hard brick recovery WIP, need dumps

I am working on getting a proper MJE SDCARD debrick image. I will need memory dumps of the boot partitions.
From ADB shell or terminal emulator run the following command
dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img bs=512 count=524288
This will place a file called unbrick.img into /sdcard (not your actual memory card (extSdCard) but your internal device memory. All I need you to do is upload this file anywhere you see fit so I can download it. I greatly appreciate your time!
At this time, I am only looking for retail SM-N900V MJE dumps.

Preferably retail, but if you have DE, go ahead anyways. Maybe I'll be able to find something new. As long as it's MJE.

That may be a problem. While baseband is MJE, ROM is CM11. That surely won't work. Sorry about that.

It won't grab anything from CM11, don't worry. These are just the boot partitions which would remain unmodified after installing CM11.

Sorry for not getting in touch - I know I disappeared as if I had died. Life - and work - intervened to the point of needing to drop something on the floor, and unfortunately that was my XDA involvement. (As it is, even this post is a little bit of hooky). But all is well; I see you are still fighting the good fight. Thanks for your efforts.

Rooting ideas and discussion

I just had an idea. What if someone roots a system.img by extracting it from a kdz and then mounting it in linux copying the root files setting the permissions and then flashing that with download mode? A simple
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
should do the trick to flash the system.img file replacing the ?????? with the correct directory.
Just a thought.
Wouldn't you have to have read/write access in order to push the system.img?
Impossible,without root.

dd if=/data/tmp/system.img of=/dev/block/platform/??????/by-name/system
should do the trick to flash the system.img file replacing the ?????? with the correct directory.

I think both of the previous threads discussing root have been closed. I haven't seen another - did I miss it?
Already tried something similar. Requires root unless you're one of the lucky few who have such advanced knowledge of hacking bootloaders/exploits....which I unfortunately am not. LOL

Apologies, I forgot they were.

Yes, look in the developer section.
It is possible to dd to partitions using download mode. The only real problem is that the root method would be huge having to include a system.img.

Additionally, you'd need a separate one for every carrier/variant.
I guess if it worked though, who cares how many we need or how big they are. Except with dd, one typo and you've got yourself a brick.

Though...wouldn't it still be able to get into download mode? I could be wrong, but that's not on the system partition from my understanding.
I'm on linux and am familiar with dd (I'm a distro-hopper and have no optical drive, so everything gets dd'ed onto usb drive).
Wouldn't we have to specify a block size on that? I know at least on linux distro, if block size isn't specified, I end up in non-boot.

Actually you are correct. The laf partition is the download mode. Flashing recovery is where we have to worry about losing download mode. (I never understood why, but at least with the G2 download mode broke when flashing custom recovery without a certain patch)

Correction, they were closed per OP request
This one is now clean, lets try to stay on topic,
If anyone feels the urge to regurgitate further horse crap... we'll see what happens

How can you confirm being able to dd to partitions using download mode? In download mode isn't the dd running from /system/bin that is mounted as ro. How could you replace /system while it is mounted and running dd from it?

linux loads commands that you are in the process of running into ram. You can even delete a file that you are running and still be able to use it until you close it. Once you close it is when the problem would occur but by that time you would already have the new file in place. Also do NOT run a
Code:
dd if=/dev/zero of=/dev/block/platform/??????/by-name/system
just skip that step otherwise you would lose the ability to dd.
Go directly for a
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
also to get a system.img instead of extracting from a kdz you could run
Code:
dd if=/dev/block/platform/??????/by-name/system of=/data/local/tmp/system.img

you can push to /data/local/tmp using adb without root.
