drk fix for g925t - T-Mobile Samsung Galaxy S6 Edge

from what i have read from other forums i see that device rootkey causes the problem of stuck at logo. this is due to efs wipe or imei repair. So i am just wondering what is DRK (device rootkey) and how can it be repaired, so we can go back to fully stock ? Thanks

The only way to fix the rootkeys is to use the engineering software and serial cable. You have to send it somewhere to get fixed or if you know someone that has those those things.
Hopefully this is a lesson to you guys for flashing things you shouldn't flash. All devices can be sim unlocked from the original carrier. In the US it is the law. If you fully purchased your device then the carrier has to give you the unlock code by law. So if you guys are doing this then you are either not very informed and you went with flashing when it wasn't needed. Or you guys are trying to steal your devices without finishing the financing. Either way it is on you guys and deserve a broken device.
Same thing with trying to root bypassing knox. For those of us not in a security or government job, Knox only affects Samsung Pay. It it really worth messing up your phone just so you can use Samsung Pay? What is wrong with Android pay? It has been around for a long time. Samsung is throwing in little gimmicks. But not really worth it for me to put my banking info on yet another companies server farm. The more places you have your info the more likely you are to run into problems with data theft. All of us were already affected by this when Experian was hacked and got our T-Mobile info. Start using the brains that we were born with.

You are not right, DRK keys can be fixed without eng soft and serial cable. Keys are located in EFS partition and can be copied from other device with same model, after copy/chmod/chown - reboot and it works again.

I also posted that info last year. Things may have changed since then. I also don't have the S6 anymore so I am not current. So at the time my info was correct. Instead you can inform us that a new way has been found. Thanks for the info.

3 Button Fix is not really a "Fix"?

I dont think the 3 button recovery mode "fix" that samsung released for Bell Canada i9000m and that was ported to work for other models is really a "Fix".
As dicussed in other threads, the original bug is on the PCB. It's a timing issue on the motherboard. The "fix" installs a software hook in the 4th level bootloader to the 3 buttons in order to trigger the recovery mode.
If you brick your phone such that it does not get to the 4BL stage ...
OR
If your phone freezes even after the 4BL stage ...
then you are **** out of luck.
Only a phone that had the 3BR working before the fix or a phone that gets a MB changed will be able to recover from being bricked.
This fix is only slightly better than installing a software that triggers recovery or using adb to force recovery mode. Basically it only works in conditions where you would not need recovery in the first place.
thats an assumption, but where is the proof and source?
I don't know about you but for me the recovery menu fix works great. I rooted my phone after I used that fix with the update.zip method so unless you have proves I think is better to not scary users.
I thought three limit was cause by the telco not Samsung? Read it from a post where the telco confirm they disable it.

The idea is I don't think Samsung replaced the motherboard of the mobile phones and the prove is that Samsung Canada or something posted a method to enable recovery mode back.

I did say "I think".... but added an ? to the title.
Based my opinion on these posts:
http://forum.xda-developers.com/showpost.php?p=8217641&postcount=390
and the serious part of this one:
http://forum.xda-developers.com/showpost.php?p=8156981&postcount=287
My reply from another thread: http://forum.xda-developers.com/showthread.php?p=8230653
That was my first hypothetis when Samsung released the fix.
That's why I asked technical details and get some after contacting Samsung technical department, to finally speak with a tech, instead of those clueless helpdesk first and secondline helpdesk coworkers. But he couldn't give me more pointers, other than the original working 3br devices do not use the spl at all.
My hypothetis seems right if the bootloader gets overwritten by other firmware who's using spl on the respective partition.
My assumption, like I said before in this thread, is that the original 3br working devices gets triggered via the pcb, which loads the pbl with the safemode, if not on a dedicated module, maybe... That way, the users of such device can always be assured they can flash every firmware. This is how it's done with other many devices too. And that's exactly why I don't buy the story of 'not'-controlled batches by another guy here on the forums in another thread. I can understand why and that's why I'm so disappointed they continue to ship the phone with Android.
If you are like me, you need to test new firmware releases in order to test your own written code in Eclipse. Plus, I want the latest releases...
That's why I suggested to get your mobo replaced now you have the change, before Samsung goes with the spl fix as a standard procedure for future bricked phones.
But, for now, we will not know, unless somebody is disassembling a working 3br and a non working 3br device and have the electronic skills to confirm this.

There is no proof, if there was, there was probably a fix already or at least the technical details published.

No, I got my phone from a Samsung distro, not from any provider and it has 3br disabled.

That could be, then if you have 3br enabled with a firmware without the integrated fix back, it's probably a new phone without replacement.
The prove that a temporary fix exist doesn't mean it's permanent, which is for the original 3br enabled devices.
So then someone should brick his phone after installed the fix and see if he can repair it back (as a user said in the original thread)

Under what kind of circumstances?
That doesn't prove anything, other than the fix works if the sbl isn't overwritten.
Then flash back to a firmware who does without the fix and tell me the results.
I've read in http://forum.xda-developers.com/showthread.php?p=8230653 that someone flashed back and the fix is gone. Now you have your proof this fix isn't permanent, like I already said a bunch of times. I believe it was firmware JM1 if I can remember correctly. It was tested one time though. Try it and please report your results back.
Proof will come when someone bricks a phone other than by flashing firmware and can not use the 3BR combo even though the "fix" was applied.
Prroving that the "Fix" works is just about impossible. No reports of the condition described above will constitute proof that it works.
I do have an idea for a test:
- With battery fully charged, USB unplugged and phone off,
- Initiate 3BR.
- Calculate time to reach recovery screen.
Compare "fixed" phone with originally working one.
If different assume that fix is not as good as a real working 3BR phone.
My Buddy just had a bad flash and and bricked the phone.. and the recovery saved him so yes it does work....
he did not have the 3 buttons working before but did the update and started flashing roms.. and it saved him... its not a hardware issue.. its always been software.
so it does work.. if this fix didn't come out he would have a good door stop.

Like I said, proof comes when someone recovers from a brick OTHER than because of a bad flash.
Because, in general, that doesnt touch the BL.

why does it really matter? isn't that normally the problem anywayz, bricking from a bad flash?
but then again, this appears to be one of those you can't prove anything to be true, but only to be false scenarios...

I disagree.
Without pcb, rom and human-machine-interaction, there is no way the bootloader will load. So you are telling me it's not a hardware issue that 3br isn't working? I fully disagree. IT IS. Why? Because Android already have the recovery / download mode adressesed... Please study mobile phone architecture or at least computer architecture and how the android kernel and os works.
No one knows the exact architecture of sgs here, but one thing is for sure. 3br isn't working, because it doesn't get handled BEFORE spl... And if it is, it's disabled on purpose in bml1 and otherwise there is probably another rom, handling all 3 buttons first, before launching ipl.
Please tell your buddy to flash back to JM1 and let his phone brick and post back your results...
I hope Richthofen and / or some other members can exclude this theory by hexcomparing bml1 from working and not working 3br devices and analyze that, so we can exclude that. If it matches, then it's probably a hardware issue. Like I told you before... Android already adressed the safemode space. So the parameters must come via the 3 buttons by pcb. You are happy now?

It seems BML1 to BML4 that triggers 3BR recovery mode are differents between countries and could be related to CSC version.
So it seems to be a software problem.
Until you dont flash BLM/SPL everything will be fine, just check before flashing.
I find it hard to believe that it would be a hardware issue.
The first retail European I9000 phones had I9000XXJF3 factory firmware version.
As far as I know all of them had a functional 3-button "wake" function for download and recovery modes.
When Samsung started using I9000XXJM1 as a factory firmware, I have seen only one phone with a functional "3-button wake". And even with that one I could not tell if it was a brand new one or a factory refurbished one.
For some odd reason the first release using the new secondary bootloader was I9000XXJM1. All of the previous versions (from I9000XXJE2 thru I9000XWJFF) have been using the same bootloader. As far as I know none of these phones ever had problems.
Also there is no indication that Samsung would have modified the hardware.
Samsung always makes bulletin about the changes in hardware and I have not seen any. Also the hardware revision has remained the same from the start.

Very odd indeed, because how is it possible that some have working 3br and others not with the same firmware jm1, coming from the same csc, coming from the same batch? Maybe the 8gb differs from the 16gb (I don't think so). Maybe asked too much, but it would be great if people can start publishing all their bml's, with the exception of the containing imei.
Because the safemode must be somewhere and it isn't in bml4.
Maybe there is a special ic for it, but it's locked for the 3br disabled phones and it's overridden by the sbl.
Are you sure there isn't a special module with the safemode in it?
That would clarify why the hw still preserves the same revision.

I do know how phone architecture works and computer architecture as well....... in the end its very simple... it works its saved lots of people from having a bricked phone.. and the recovery mode is different between countries. besides you should not be flashing the SPL/BLM in the 1st place. and like you said your self you don't know how the exact architecture works on the SGS so how can you say its not a software issue. if you fully don't understand it.

T-mobile S4 Stock Android 4.3, Cannot Unlock, IMEI unknown after attempt by localshop

Hi All,
I had purchased T-Mobile Samsung Galaxy S4 (SGH-M919) with Stock android 4.3 while I was in usa, and want to use it in my home country now as I have left usa. I couldn't found any unlock solution on internet for stock android 4.3, and T-Mobile would not give me the unlock code. I tried third party services to provide unlock code and it did not work either. So I went to a local shop, and he screwed everything up. When I went back to the local shop to receive my phone (hoping it might have been definitely unlocked by them), he told me that he tried to downgrade it to 4.2.2 but it did not work (only after reading through all the forums I realize there is no way to go back to stock 4.2.2 if you are on stock 4.3 because of knox / bootloader issues on 4.3, leads me to think the shopowner did not really do his research before touching my phone, and no, he did not do any EFS backup). In an attempt to unlock my phone, he also flashed Metro PCS stock ROM on my phone, not to mention, my IMEI number is also 'Unknown' now. I managed to get back on T-Mobile stock 4.3 ROM now but still IMEI is unknown. I also tried to go to nearest Samsung center and they said they would not touch international phone models. At this point I have no idea what to do. Any suggestions how to get back my IMEI and or at the least to get the phone working to my country's network?
Thanks.
Try flashing the mk2 modem using odin. That may work but not sure.

The local shop broke it. Tell them to pay for it.
Also, the only reason T Mobile won't give you an unlock code is if the phone isn't paid for in full. If the phone is paid for in full, they HAVE to give you the unlock code.
Are you sure you didn't buy the phone in the US, then leave the country without paying the bill so you could use the phone internationally without paying full price? If not, there is no reason T Mobile wouldn't give you the unlock code. So there's some missing information in this story.
Also, we do not discuss how to change IMEI's on XDA. The only thing permissable on XDA about flashing IMEI's is restoring YOUR OWN IMEI from a backup. That is done by restoring the EFS partition. But you didn't have a back up so you can't do that. That means anyway to fix your IMEI involves what is an illegal hack and that discussion is expressly not permitted on XDA. That information is used for illegal purposes and XDA is not going to be the place where it's shared for legal reasons.

Hi skipjacks, thanks for responding. Nothing is pending with t-mobile, I was on prepaid account. I bought the phone like 10 days before leaving usa (due to emergency). T-mobile says my number on this new device should have being working for at least 45 days or so with refill balance. My cycle ended after 15 days of purchase and I really didnt see any reason to refill it as I was no more in usa. And no, I dont want to CHANGE my IMEI, only want to restore my own IMEI only. I am not sure if my EFS partition is corrupted, because I rooted my phone tried to backup EFS folder now (I know its too late but still), deleted it and rebooted (as a few threads suggested it would regenerate nv data files), but neither did I see any nv files when I did a back up now, nor after I rebooted. When I rebooted, the EFS folder did regenerate but there were no nv files in there. Also, after deleting EFS and regeneration the serial number was corrupted, but when I restored my backup, the serial number showed up correctly again. Also my current backup contains the imei folder with mps.code_bat file. I noticed that even imei folder was not regenerated on deletion of EFS and reboot. I somehow have the feeling that this is still indicating that my original EFS folder is still present (though I may be wrong, because I dont know). But my concern is the nv data files, which I dont see anywhere. I did come across several threads about imei corruption and restoration, but the only one I didnt come across was T-mobile SGH-M919 with stock android 4.3. I am wondering if this has some different file storage structure for imei (which again I dont know). At this point I am concerned about getting back my imei, I can get the unlock code from some reputed paid service again. I understand that open discussion about imei involving anything CHANGING IMEI is not allowed here. If anyone could just help me out restoring my original imei, even by pm, I would really appreciate it. I just dont want to throw away the phone and lose my money because of the error done by repair shop.

First off....the enter key is your friend. Hit it every so often when typing giant blocks of text like that. :laugh:
Second, since your IMEI has been deleted, you now have to change it, even if you just want to change it back to what it was before. The process to fix it now is what can't be discussed here.
IF you had backed up your EFS partition, then it would be as simple as restoring it in recovery. That's all well and good. But your IMEI is now 0, so you have to change it to what it was.
But all that aside, you went to a store and they broke it. Take it back there and raise holy hell until they fix it for you or buy you a new one. I know consumer protections are stronger in some countries than others, but wherever you are, yelling and screaming is a universal language.

Whether your file is missing, modified, or corrupted, you need your /efs folder to restore it. You do not have have a nandroid backup or the /efs folder. I am sorry but the simplest we can put it without sounding harsh, you're screwed. You need to request the local shop give you a replacement phone or credit to get a new one.
Update: I went back to the shop and told them "You broke it, you fix it, I don't know how and I don't care, you gotta fix it". They managed to fix the imei number somehow. Regarding unlock, the shop ended buying the unlock code themselves. They mentioned that no one is able to unlock T-Mobile S4 with Stock 4.3 as of now without unlock code, unless they have some device like Z3x box. The phone is finally unlocked and working fine on my network. (YES, A HUGE HUGE RELIEF).
Everything is fine, except for 2 issues.
1. I want to backup my EFS folder so that I don't enter into trouble with IMEI again. I tried EFS Pro, but its not working. All I see is "'Initializing ADB server..." (the phone is rooted, usb debugging mode enabled, and supersu permission granted when prompted). I also tried to backup using Andromizer, but it says "Notification: File not found in /storage/emulated/0/Amdromizer/efs/efs.img". What is my best option as of now to backup and store my imei safely somewhere?
2. I am having issues with Wi-Fi. Before the shop flashed my phone, it was all good, but now it doesn't auto-connect to my home Wi-Fi anymore. Everytime I reboot or get out of range, I have to manually select my home network everytime and also enter the password everytime. Nothing has changed on my router. The other Samsung device that I have still auto-connects to my home Wi-Fi as usual. How can I fix this?
Thanks.

For the efs you can back it up using recovery. Just boot to recovery and its one of the options in the backup menu. The resulting file will be like a few KB. Its supposed to be small. Dont worry

[Q] Restore original IMEI without a backup

Device : Samsung Tab S 10.5 LTE (SM-T805)
As the subject says (and a few others on the site). I neglected to backup my EFS partition, so now I am unable to connect to a mobile network.
I have researched many guides, but all are for other phones (though still Samsung).
Only my IMEI has been reset, so I am just attempting to restore it to its original, which is printed on a little sticker on the back and on the box.
From the other guides, my stumbling point is getting into the Qualcomm USB Settings and changing to RMNET + DM + MODEM and then getting back to MTP + ADB. But the codes to get into such settings must be different for each device or group.
Can anyone help?
List of things I already have available :
A PC (Windows 7)
EFS Professional
QPST 2.7 Build 231
NVEditor v1.5

From the other guides, my stumbling point is getting into the Qualcomm USB Settings and changing to RMNET + DM + MODEM and then getting back to MTP + ADB. But the codes to get into such settings must be different for each device or group.
Can anyone help?

Would be highly interested in a solution for this too :l
First time Samsung (never had a Problem with any of my HTC :x ) so I didn't knew the IMEI get's corrupted :l
It's not going to work when you have an Exynos device and not qualcomm.
How did you lose the EFS?

Dunno, somewhen inbetween :x
Could've been from a 5.1.1 ROM
The ones before worked fine, then I used some w/o working radio and now no more efs :l
Guess I'll have to "accidently" brake it (insurance and stuff).

Have you restored stock firmware, do you get any imei at all?
Also whats the point in breaking it when you can take it to a phone shop, get them to plug in with the z3x box and repair it?

Got the same "broken" IMEI again.
Don't think there's a shop near here with a z3x (Nuremberg, Germany).

Z3X box is currently unable to fix this.
Samsung were not even able, they wanted to replace the motherboard for £250.

Well it seems to manage on plenty of other Samsung devices.

£250 for basically just a software flash which they are more than capable of doing.

Yeah, I wasnt pleased either, I was assured via email that it would not be a problem and wasnt quoted anywhere near that.

(MDM) Firmware install, now hangs on Tmobile logo

I got an S9 that has MDM, when I try to install new firmware (Odin) it is getting stuck on Tmobile logo. I can install combination firmware no problem. How do I proceed? I would like to try the incorrect-pin-factory-reset method but now I can't get it to boot up.
Thanks

Most devices with mdm are rent a center devices here in US. You need to make sure it's not still owed by them. More than likely it is. How did you aquire this device?

I am aware of the RAC mdm software. Most of the threads I've looked at for guidance involve RAC devices. This one is actually from a company in Missouri called "Fairbanks Scales". I purchased it on Ebay, it was listed as Googled Locked and the IMEI was clean. I've reached out to the company to ask them if the phone was lost or stolen, or if their IT department would be willing to release it from their KNOX enrollment. They are looking into it, they don't have any record of the IMEI. I don't know if they are going to help me, and it's running 9.0 so the incorrect-password-reset method seems to have been patched.
I do have the ability to enter download mode. It allows me to flash combination firmware. Anyone have any tips? Thanks

Well if you found it maybe you should turn it into your local police agency or what ever carrier
No one is gonna help you with this on here as your using a lost or stolen phone which we do not support
since you found it maybe some one is missing it and would like it back?
The security you are encountering is put in place just for people like you

I totally agree with what you tell me, but I found it into a garbage and the display is not working well, some parts of the screen are not showing nothing.. so I think that no one is missing it now
