Looking forward to hearing someone's results!

I can say that I do not believethis currently will work on a T999L, T999N, T999V. None of their firmware is compatible with each other. For example, if you try to flash ones firmware to another, it will cause a device to hard brick. So until versions for each model are posted, I wouldn't try this on anything but the T999.

Thanks for posting OP. Hoping it works!
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Sent you a PM requesting the T999L emmc dump. If we can get all the T999 Variants in here then it would be awesome. Apparently the fallback boot on the S III when the bootloader is corrupt is externalSD so we just emulate the bootloader onto the microSD and it booted perfectly for me when I bricked my wife's T999
[T-Mobile, Samsung Galaxy SIII] Qverse:
Wow

This is truly a great thing !

Cant wait to see other the emmc dumps and to hear of results . The benefits of something like This is 10+ :good::good::good:

Thank You. :cool:
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Can only wait until those in the Help/Q&A thread make it over this way. I'll try to get a video posted up later today.
[T-Mobile, Samsung Galaxy SIII] CNexus:
Just wanted to clarify that gTan64 was the one who originally discovered this method while trying to fix a friend's bricked Sprint S3. He didn't actually brick his own S3

And to elaborate, it's not so much a fail-safe but more of a built-in feature that allows these phones to boot from an sdcard because you can do this even if your phone isn't in QHSUSB_DLOAD mode
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Thank you. I almost had all the details correct :) I will edit the OP to properly state that when I get back to a PC
[T-Mobile, Samsung Galaxy SIII] artojeda1988:
does it have to be on linux can i run it through command cmd on windows?
[T-Mobile, Samsung Galaxy SIII] Notorious:
Has to on Linux or using Cygwin
[T-Mobile, Samsung Galaxy SIII] WhoWhere:
This is great news! I'm excited to hear confirmation.
[T-Mobile, Samsung Galaxy SIII] Chefedogg:
I was searching for this emmc dump all last week, sent my phone out to get jTagged, get it back today and now I stumble across this :laugh:

Thank you very much kind sir for hooking us up!!
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
If you use this method please respond with your results as to show users that it has worked for you. If you would like to help with this for other variants of the S3 please inform me and I'll work with you to get what we need.
[T-Mobile, Samsung Galaxy SIII] absinthesummer:
Don't mind me, I'm just adding a link to ubuntu live cd to make the resources easier to access for those who need to try this. I hope that is OK with you. If not, I'll remove it.

BTW, I did not quote the entire OP lol, just the list ;)
[T-Mobile, Samsung Galaxy SIII] HolyGhostBoy1:
do i have to have a sd card reader or can i use a program to write it to my sd card
[T-Mobile, Samsung Galaxy SIII] absinthesummer:
I would probably add the file to my sd card via the computer, and go from there.
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
What hardware do you have to use to copy to the image?
[T-Mobile, Samsung Galaxy SIII] cy_mpak:
i have hardbricked t999v and can test this if i get debrick image
[T-Mobile, Samsung Galaxy SIII] liongvn:
Fixed.But it don't write any data to sdcard.

Hope you can make a video soon :(
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Can you explain what you mean by your statement?
[T-Mobile, Samsung Galaxy SIII] philow:
I looked in /data/media, /media/data/0, and /sdcard nothing there tried it twice
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
try /data/media/0

/storage/sdcard0/

if you want to confirm it fladhes, before leaving recovrry copy log to sd
[T-Mobile, Samsung Galaxy SIII] philow:
Argh!!! Still nothing. The log saved fine. Here is the info of the flash in the log:

Doc

It is not saving this Debrick file as I searched all the directories for .zip files and apart from this file or in fact there is no file created today

It confirmed that this file is not saved /created

Any suggestions
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Im not sure it is working for you guys. I dont like how it says "Aborted" on the one line.

Dont worry about it for now though. We can get someone else to try as well and see if we cant figure it out. 4Orr said he would give it a shot, and we know it worked for him before.

Thank you all for your efforts trying to help me out though!
[T-Mobile, Samsung Galaxy SIII] 4Orr:
I was able to generate the debrick.zip for the MD5 firmware. I will upload it shortly. Fingers crossed!

---------- Post added at 06:56 PM ---------- Previous post was at 06:38 PM ----------

Check your email Doc.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
will give it a shot in a few, thanks man!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
well ive tried just about all i can think of. really wish i knew why this seems to work for most, but not a few.

as much as i hate admitting defeat, and giving up, i just dont see spending more time on it as productive.

ugh...starting day 3 with no phone...feels like a week! its funny how we used to get along so well without these things, and now you feel totally disconnected and incomplete without them!!

for those who want to know, im going to try to go without long enough to save for the insurance replacement. (if i put my sim in another device i will lose the ability to do so). i know if i dont get another at $150, ill regret it. ill still try to upgrade soon, but this will be the cheapest way to have a good backup and something decent i can hand down at the same time.

plus itll make it easier to continue on in these forums!

just have to see if i have the will to do without for a while! lol! (anybody know if payphones still exist??! j/k)

thank you all again for the time and trouble you spent to try and help me out!
[T-Mobile, Samsung Galaxy SIII] jonk26.2:
Doc...I have 2 spare motherboards...one has a bad imei....the other has a bad microphone and a bad accelerometer...let me know if you would like me to loan one or both of them to you.
[T-Mobile, Samsung Galaxy SIII] 4Orr:
We were honored to help you out for a change, Doc. I'm sorry you weren't able to revive your GS3. I know if there is anyone that can figure things out it's you.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
thanks for the offer! i will definately consider it, and if i were interested, woukd you consider selling as opposed to loaning? (we arent allowed to actually buy/sell here, so dont post pricing or stuff like that, if youd be interested ill pm you my email if i decide to go that route.)

as for a loan, itd probably be too much trouble to be worth it for both of us since we are just talking about the mobo. not something id want to gaurantee i could remove and return in the same condition.
[T-Mobile, Samsung Galaxy SIII] anil2653:
We are doing this because we don't want to miss your so much support for T-999 users

But is very sad that we could not ...

[MENTION=3505796]KAsp3rd[/MENTION] how do i repartition my sdcard back to normal it says it only has 2gb on a 32gb card after deleting the unbrick files tried reformatting bbut isnt working . dont know linuxx very well maybe i have to do it on there?? thanx
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
i just put mine back in my old phone, and selected erase/format sd.

---------- Post added at 10:44 AM ---------- Previous post was at 10:41 AM ----------

hey guys, would someone be willing to make another debrick img after updating to the official 4.3? cant hurt for me to try, can it!?

you will of course have to odin flash your recovery again after the update.
[T-Mobile, Samsung Galaxy SIII] javichampi:
I used minitool partition wizard in windows, and i removed all partitions without problem. You can use gparted on Linux too.

[T-Mobile, Samsung Galaxy SIII] anil2653:
Official 4.3?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Yup Yup! And they just couldn't wait for me to get a replacement, lol! Thread in General announcing the release. I will have it uploaded to my AFH for fast download in about an hour probably.

For now though, you can get it via OTA, maybe, or from samsung-updates.com or sammobile.com
[T-Mobile, Samsung Galaxy SIII] anil2653:
Firstly I need to be on stock to update ota

Should I Odin to stock rom?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
id wait a few. i shoukd be able to get a faster download ready before you could downliad the full update. you can do that if you want to try though. flash back to md5, then try to get the ota.

your calk there though.
[T-Mobile, Samsung Galaxy SIII] anil2653:
I have md5.tar uprooted firmware with me

Should I Odin to stock with mobile Odin
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
no, dont use mobile odin for this. the ota would fail. M.O. doesnt flash tge full firmware.

my upload failed so had to start over. gotta leave for a few hours so ill post when i get back.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
link to 4.3 firmware in the General thread. sorry, didnt have enough time to post here too.
[T-Mobile, Samsung Galaxy SIII] philow:
ARGH!!!! I tried again after ODIN of the Stock and then ODIN of TWRP and it still will not work for me :( Log looks just the same as before.

Sorry, I tried!
[T-Mobile, Samsung Galaxy SIII] 4Orr:
I'll be glad to try to generate the debrick.zip, but it'll have to wait until my three girls are fed, washed and tucked into bed.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
i really do aporeciate the effort man! thanks!

sorry i cant figure why it doesnt work for you.

no problem. got my girl for the night, so i fully understand!
[T-Mobile, Samsung Galaxy SIII] 4Orr:
Ok, I Odin flashed the newly updated original firmware you posted then flashed the recovery and tried to generate the debrick.zip. Something is blocking the script from running and thus generating the file. I then tried Odin flashing the route66 MD5 firmware and it failed! I guess I'm stuck stock until someone figures out how to undo this.

Edit

I restored a nandroid, everything worked except lost my IMEI. Now how do you restore that again? Any takers?
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
I now know why the <=MD5 images wouldn't work. 4.3 is a one way upgrade. Problem is, the zip doesn't work. I flashed CM so I could see the filesystem without signing back into my Google account. mmcblk0 is there. CWM gives no error, TWRP says it's not there. So, maybe need to wait for a recovery update? Not sure what else I can do, already removed all the variables from the script.

Edit:

I was able to convince it to work. The scripts are at least partially broken, both of them.

On Kasper's, the syntax is incorrect.

On Doc's, the size is 128KB.

The OP says you want 128MB.

dd "if=/dev/block/mmcblk0" "of=/storage/emulated/legacy/debrick.img" "conv=sync,noerror" "bs=65536" "count=2048" is resulting in a 128MB file. the 64K and 1M were resulting in 128KB files, indicating that (at least) CM's version of busybox is not interpreting these correctly. The math adds up, but the filesizes weren't.

Uploading now, will edit post with Dropbox link when finished. If you need anything else pulled, let me know.

Edit: https://db.tt/6ZD9TtPr good luck.

Edit 767: I didn't test this script, but it should work. Fixed syntax of dd command and made it 4.2+ friendly. Could also use busybox's tar instead of third party 7z, reducing size of download.

#!/sbin/sh

export PATH=/sbin/busybox:/xbin/:$PATH
mkdir -p /storage/emulated/legacy/Unbrick
# backup bootloader partition
dd "if=/dev/block/mmcblk0" "of=/storage/emulated/legacy/debrick.img" "conv=sync,noerror" "bs=65536" "count=2048"
#now we zip the file to make it take up a lot less room
/system/lib/p7zip/7z a -tzip -mx=9 /storage/emulated/legacy/debrick.zip /storage/emulated/legacy/Unbrick/* -R
rm -rf /storage/emulated/legacy/Unbrick
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
wow man! Above and beyond as usual!

Can you verify for sure though abou 4.3 being a one way update? i had heard this as rumor some time ago, but could never confirm. But then i started hearing about a bunch of people flashing back to older firmware after experiencing bugs.

i will give that file a shot her in a few and will report back! thanks again! you rock! :cool:
[T-Mobile, Samsung Galaxy SIII] anil2653:
My bad luck

Downloaded multiple times but md5sum mismatching

Now selected different mirror and downloading again
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
use any mirror but IL.

they had a ddos atrack earlier.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Just a thought, it may be more related to the recovery being used, as far as the file sizes not being correct. I know one person flashed the script and got a 64mb image, then others couldnt get it at all, while others got the full 128MB file as expected. So the most likely variable I can think of is the recovery.

Though I will say that something you did, did have a tiny effect on my phone. The first time I used your file on sd, my phone actually vibrated for a second!!! Then it vibrated again! It did the same when trying to power on normal, download mode or recovery. But all i would get was the vibration. Nothing else.

Now, every time I try it, I once again get nothing. Ive remade the sd card several times since and just cant get anything. A small spark of life to get me excited and then just tear me back down! No idea why your file seemed to do that the first time, but will no longer.
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Thanks for helping everyone out here. I have been busy at home and work and getting ready for a move to Denver.

Also what syntax are you seeing as incorrect? It was tested and verified when it was posted.

As far as using tar vs .zip I wanted to make it as simple as I could for the user to extract the unbrick image and piping tar to gzip/pigz didn't want to work with busybox on either CWM or TWRP. The original script I wrote was tested with both CWM and TWRP however I cannot remember which version of each I was using and busybox could have very well changed since then.
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
I have the 4.3 updated on my sIII at home however it doesn't have a custom recovery at this point. I'll flash one when I get home tonight and see what I can get for you if you still need it doc. Won't be until around 2000 Eastern
[T-Mobile, Samsung Galaxy SIII] calexchelse:
In just wondering if the new warranty bit in download marry have been what killed your phone doc. You may want to look at the for that you flashed that actually bricked it to see if there are any strange or different looking scripts than normal

TW 4.3 WITH A TOUCH OF KITT KATT
[T-Mobile, Samsung Galaxy SIII] scifan:
That's a possibility... could be something along the lines of it's looking for a particular bit in that block and when it doesn't find it as expected, it shuts down... not sure...
[T-Mobile, Samsung Galaxy SIII] calexchelse:
Maybe remove that bit, then try Odin. But I have no idea if that is possible

TW 4.3 WITH A TOUCH OF KITT KATT
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
It has to be an issue with busybox. The problem was with the if arguments on yours, file not found. I removed them and got a read error. CWM and TWRP.

It's also not interpreting K and M correctly. This part was tested with whatever version of busybox CM 4.3.1 is using. Using the integer value fixed that.

I've used tar before and not had issues. Though admittedly it was through Android not recovery.

I wonder if pulling more for the debrick image would help. Maybe the partition layout is different or something.
[T-Mobile, Samsung Galaxy SIII] Vigz:
Alright, I have an S3 that was on the latest 4.3 firmware. I hated this Warranty Bit nonsense so I tried relentlessly to get the UVDMD5 bootloader back. After a while, my phone was bricked. My computer detected the phone and installed a driver called QualComm something.... Anyway, I am about to invest on a 16gb microSD card as stated in the OP. I have one question though, I have an SD card reader, will this tut work if I insert the microSD card in an SD adapter? Thank you very much.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
you may be right. all i can confirm is sbl3 is what ultimately caused my brick. no way to

check or change at this point though.

i will keep trying anything and everything! do you think it could be possible i need a larger than 128mb image?

it should be fine as long as it allows you to write to the sdcard from the computer.

good luck!
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
I'm unsure, I'll take a look at the SIII when I get home and see if the partition layout has changed. This whole KNOX **** is killing phones left and right.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
i dont see how the partitions would be changed. would cause a huge amount of problems. On the S3 i dont believe knox to be as big a problem as everyone seems to think. its not implemented like on newer devices. the biggest issues are tge warranty bit and seLinux imo. i could be wrong, but its where im at in my understanding of it right now.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
I'll get a full system dump for you. If that doesn't fix it, just throw it away :cowboy:
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Looks like I'm out of the support world for the Siii at least when it comes to having the device. My mother in law decided she wanted to purchase it so I've not gotten my new device (sold the htc one also {got the Nexus 5}) and the Siii is back to stock in a box awaiting delivery. Sorry I cannot offer much more on my side other then my knowledge.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
ill have to look at the vid. only glanced at it before. but for the dd command to work on a live cd you will have to type sudo in front of dd.

sudo dd if=/....../.....

Very much aporeciate everything man! But for my part, i dont want you to take any undue risks to try and help me. Youve purposely bricked more than any of us should ever expect! Last thing i want is for you to become unrecoverable too!
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
He's in the same situation as you. Flashed 4.3 then tried to flash older firmware. I'll be working with him tonight in irc as soon as I get some down time.

Not going to brick it this time LOL. I am a tad concerned with flashing a custom recovery now the the siii is fully stock 4.3
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
custom recovery should be safe to use. and just so we ate on the same page, my brick occured from flashing from 4.1.2 up to 4.3.

sbl2 flashed fine, no issues.

flashed sbl3, rebooted, seemed good. rebooted recovery and it never came back on.

---------- Post added at 10:09 AM ---------- Previous post was at 10:04 AM ----------

quick question

do you know if it will attempt to boot from sd if not bricked?

or does it have to fail normal boot before attempting the sd?

if itll boot from sd, without being bricked it will mean 2 things. people can test a debrick solution before taking the risk.

more importantly, it could be a way to boot MD5 bootloader so those stuck on 4.3 might be able to downgrade, regardless of tge warranty bit.
[T-Mobile, Samsung Galaxy SIII] foreverthewolf2012:
Just a tid bit of info

When I flashed Odin 4.3 stock I was able to use that Cyanmod Installer so I could get root and it installed clockwork mod also and then I flashed back to a 4.1.2 rom and then I used a zip file of twrp 6030 and flashed that and that worked but I tried to install the 4.1.2 radio and that wouldn't take it was still stuck on the new radio for 4.3 and wouldn't give me any signal at all and then I flashed that firmware / recovery n stuff for 4.1.2 and that's when it bricked
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
It required the emmc boot to fail before it would boot to microsd
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
so it was the recovery flashable firmware that ultimately bricked you. that makes 2. its enough for me to call it confirmed. thank you for posting the specifics! very valuable info to have at this point!
