JTAG Help? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I've got my RIFFbox, and I've been able to connect to the device just fine. I can send the resurrection to the dead body, but I can't get it to boot to Odin mode still. When connecting to PC, it still shows the QPST download mode (QDL mode). I'm currently trying to flash individual partitions to the device.
Any help or suggestions to get this thing out of QPST mode? :/
Thanks!
I've tried 301k & 619k JIGs also, and several known combinations of keys to boot Odin mode.
UPDATE [7-23-13]:
At this time, I've determined that this device is permanently bricked until I can get my hands on the Kies MF3 Odin package and manually load these files via JTAG. However, even this is not guaranteed to fix it. For the time being, I've replaced the device. I'll hold onto the carcass for a little while longer to see if I can get MF3 to boot on it. If I can, I will use this as a test bed for developers to attempt to unlock bootloaders or develop an MF3 root. Otherwise, I eventually plan to part it out, selling things like the screen, etc.

Yup. No reply yet.
Currently flashing the whole 1GB image. Takes forever, so I will let you all know how it goes in a couple hours. I haven't tried flashing the whole MF3 boot chain but it's looking like that's what I will end up needing to try.

No go on the full 1GB flash. In a last-ditch effort, I threw the MF3 version of SBL2, SBL3, ABOOT, TZ, and RPM at it.
Still boots to QHUSB_DLOAD mode.

This is unbelievably frustrating. No matter what I throw at this thing, it refuses to boot. Also, it seems that the only people that know how to JTAG one of these things are not responding.

Try getting a hold of Josh over at mobile tech videos. I believe he goes by connexion2005 here on XDA.

Thank you, but he was the first person I tried contacting. Seems to ignore my PMs, or just doesn't have the time?

He's pretty busy most Days. His business takes up most of his time.

Have you tried contacting @AdamOutler? If I remember from the early Captivate days he worked with Josh to get the JTAG stuff working. He's definitely very knowledgeable when it comes to Samsung hardware.

I'm pretty sure you need a JTAG flash with an up to date firmware. There was someone else who's device refused to boot and he managed to unbrick with software. I take it that this is due to messing with bootloaders and trying to revert? btw... quote or mention usually gets my attention.

Yes, this is from flashing MF3 Sbl2 and Sbl3 (without aboot and tz). I've tried flashing the whole MF3 bootchain, and it still doesn't like it. Still boots to QPST mode.
EDIT/ADD:
At this point, I've flashed these:
PGPT (and SGPT) from the 1GB "full dump" provided by riffbox (assuming MDB or MDL - it was released 7/3/13)
PIT from the forums around here somewhere (seems identical to one from dump)
MD5 from dump
(empty area) from dump
apnhlos (aka non-hlos) from MF3
MDM from MF3
sbl1 from AdamOutler's MDB dump
sbl2 from MF3
sbl3 from MF3
aboot from MF3
rpm from MF3
tz from MF3

Yeah, tried it all again, for good measure. Starting to wonder if this thing is completely and utterly bricked? It makes no logical sense. Something is still triggering it to enter QPST mode. Again, I've tried using 301k (and a few other) Ohm resistance JIGs to try booting immediately the flash. Nada. Using the 4.2v power supply from the Riffbox, tried USB power (kinda difficult to flash things solderless when the daughterboard is attached, but possible), tried battery power only... All appear to work fine in Riff, all allow me to read and write any address I want.
I'm about to the point where I'm going to scrap this for parts to help get a new one. :/

Could sell for parts for around 300 or so ?

Adam is right, you did get the newest firmware they have online right?
Did Derek get hold of you? I had him busy at work today, he had to load 50+ laptops with win 7, big money involved, I will IM him for you.

@AdamOutler @Aou
same exact thing happened to me i did the same thing with the verizon update and sent it out to josh @ mobiletechvideos.com
just got my device back today and its still Bricked !?!?!?!? either josh and his guys just failed to test it or there is no way to fix these phones
1. this really pisses me off i sent it to the most reputable guy in the buisness and got it back in this condition.
2. for the odd case that its just a complete loss i have one thing to say to samsung, vzw, att....
basically moral of the story is i wouldnt sell your phone for parts to get another wait until i/we hear back from mobiletechvideo then sell you device and never buy a samsung device again as long as it is locked

I've been a diehard Samsung supporter since the GS1 came out. The hardware quality is awesome. Unfortunately, their policies are beginning to become unfriendly for developers. The issue you're having is due 100% to Samsung's desire to lock people out of custom kernels.

Isn't it AT&T and VZW who are locking it?

I got the latest firmware that I could find - but it's dated 7-3-13 (a week before the MF3 patch). Does Kies have MF3 yet? I might be able to live with MF3 if I were able to retain a custom recovery and therefore root (via injection). It'd mean no custom ROMs until a new "Loki" (or equivalent) is made, or we get these blasted bootloaders unlocked.

I would REALLY like to hear what the deal was with mobiletechvideos.com & @connexion2005 has to say about our situation here. My plan was to cut my losses on Monday if I am not able to get it fixed this weekend. This is really crazy news for me - Josh is indeed the most reputable JTAG guy in the industry (afaik). For them to send that back still bricked is a really bad sign! (Makes my situation look pretty much hopeless!)

Indeed, I've had the Infuse, S2, and now the S4. I love Samsung's handsets, and I traditionally loved how much modification you could do to these handsets to customize them. However, with locked bootloaders and such, this is becoming quite the joke - and the joke's on us, it seems.
----------
As an update to my situation, I haven't tried anything new since my last post. Still waiting to find new ideas or hear some suggestions.

I screwed up my S4 recently and it was being fixed (hopefully) from MobileTechVideos. Josh is really a good guy and back in my S1 Cappy days I had to send one to him. We chatted on the phone about android stuff quite a bit back then.
So I screwed up the kernel I believe trying to make a kernel splash screen, flashed in recovery and when it rebooted I just got a vibration every 3-5 seconds. Tried Odin MDB and MDL firmware with both always passing. But still same results when it went to reboot.
Now seeing this comment you made has me actually worried now. Have you contacted them about it still being bricked yet? Or did they send it back with refunding the charges since it wouldn't work? Crap it I f'ed it over after only 1 week of having it and it cannot be resurrected. Now I know my situation is different as I have NOT messed with anything from MF3 at all. But if something else is going on inside that MobileTechVideos couldn't fix has me worried.
Also @Adam, I feel the same way about the quality of the Galaxy lines as I have had the S1,S2, S3, and now S4. But I am seeing the writing on the wall with Samsung and ATT showing me this COULD BE my last of them.

I think my focus may be completely bricked, no logo, no vibration, no pc detection.

To start I am new to the Samsung Focus and the Windows Phone 7 modding scene. The only background I have is with Android and the Samsung Fascinate.
I have been battling with this focus for a few days.
When I first got it it would not start up at all, only bootloop at the Samsung logo.
I then figured out that the phone would boot up if I removed the SD card. I know for a fact that was the SD card that came with and has been in the phone until now.
The phone when connected to pc or the wall would seem to not charge batteries. I have 3 working 1500 mAh batteries between my fascinate and this focus and the focus would not charge any of them.
Then I flashed MAGLDR, or at least tried to. It failed the first time during installation, and worked the second time.
I then attempted to flash cleanrom 3.10a. The installation program said it had completed sucessfully, but alas I only got a bootloop.
Then I flashed 1.3 stock rom sucessfully, but still a bootloop.
I just tried to flash the 1.4 stock rom to maybe kick it out of bootloop, and during the PDA flashing the phone got stuck at 13%. Unlucky number, eh?
After 15 or so minutes I decided to unplug the phone and pull the battery.
Uh-oh.
Now, with 2 different batteries, which I know are charged, the phone will not boot into the logo, download mode, or format mode. Pressing the power button does nothing. The screen remains black, and plugging the phone in after holding the download mode buttons does nothing, my pc does not recognize any usb device being plugged in.
Now I am completely stuck. Is it a paperweight or can I still save it?

Are you saying you have a Version 1.3 Focus and you flashed the Version 1.4 stock ROM? If you did, then yes, you now have a bricked Focus, and I don't believe anyone has found a way to repair that. NEVER flash ver 1.4 ROM to a ver 1.3 phone, or vice versa. Sorry about your troubles...

Yes I guess I did. There was no place that I could find that ever stated the difference between 1.3 and 1.4. I saw something online about being able to recover it with a JTAG service (sending it out to someone with a RIFF box and have them jtag it back to download mode) would that even be possible?

For starters, please don't take my previous message as scolding you for flashing the wrong ROM. Believe me, it happens to all of us at some point. I did it to an HD2 and bricked it.
I don't remember anyone recovering it with JTAG, but if there is a way, I'm sure that's it. I would suggest you follow up in the thread where you read that and see if anyone there can confirm they have done it successfully. Good luck, and again, I'm sorry about your phone.

I only found one website that seemed legitimate (he had youtube videos with 40,000 ish views) and honest. He explained that the JTAG method could fix dead-boot phones like mine, and if not then the price is refunded. It's only $40 for the service, but I'm a poor high school student. Once I get the money I will definitely follow up in this thread. :good:

Be cautious of those sites, and get references. There are many sites that "Say" they will do something and if it does not work, they will refund your money. But when you don't hear back, you've lost your money, and possibly phone. It's really hard to get a refund at that point.
There are MANY iPhone Unlock Sites that do nothing more than take your money, never to be heard from again. They look legitimate, but it's really hard to tell from a web site that can be built in an hour or so.

Duly noted. I will definitely do my research. Also I will probably go to a site that uses paypal so I can take advantage of their buyer protection policies.
I would consider getting a phone off of ebay with a cracked screen and strip out the main board, put it in your phone.
Make sure you flash with the correct firmware.

[Q] Can I replace build.prop with Stock Recovery or Odin

Ok, I've looked around for the answer and from what I've ready, I don't think I can do this but I want to make sure I properly understand what I have read.
My phone came stock with AT&T's MF3, i was able to successfully root and debloat the phone without issues. I was very careful the entire process and everything works perfectly. But then what did I do? I modded the build.prop (it was late and I was tired... I shouldn't have done it) file without thinking "I don't have a recovery method if this fails"... I KNEW there was no MF3 firmware available for recovery in Kies, and I knew no one has found an workable solution in Odin... But these didn't cross my mind that night. So, when I rebooted my phone, it would go past the samsung boot logo but never show AT&T's logo. The screen goes black after the Samsung logo, the remains black. After about 10 - 20 seconds the LED at the top left of the phone will turn on blue and throb. If I plug my phone into a USB port, it will try to install drivers as "MTP USB Device" but fail. The longer I leave the phone the warmer it gets regardless of whether or not it's plugged in.
I can boot into Download Mode and Stock Recovery
I've tested the drivers with my wife's phone and everything works as expected
I can boot into Stock Recovery and sideload files (I tried to flash an OTA file another user hosted here, it was sent via ADB sideload but it failed due to my debloating the /system/apps folder)
I've tried using stock recovery to flash a zip file to replace build.prop, but failed (not signed by samsung)
I've successfully flashed the "MF3_BTL_FIX" file another user created to kick a person out of the yellow triangle, when Kies fails.
I've tried best buy, but the samsung specialist will not even plug my phone into their computer
I have a backup build.prop, I just can't figure out how to get it on my phone without a custom recovery.
So, is there any way to replace the build.prop file with Odin/Heimdall or flashing or sideloading something from stock recovery?
My wife has the same phone, so I can also get files from her phone if I need to.
Any help or advice (even if it's "you have to wait for MF3 to be released in kies") would be greatly appreciated.
I'd find another bestbuy and see if you have better luck there.

Unfortunately, yes... It formats /data and /cache... it doesn't touch /system at all (from what I could tell), so the build.prop isn't restored to factory.
What stinks is, I believe ALL i have to do is replace that ONE file! Granted it's a major file... but still, ONE file, keeping me from booting to the OS. I've even been tempted to send it to one of the guys that does the jtag repairs, but to be honest I don't know enough about what they do to know if it would even help or if I could trust them (I assume I could from what little I've read)...
I may just have to go best buy hunting.

I know I've heard of mobiletechvideos before, and I know they would be trust worthy, I've heard GREAT things about them... The other place I saw unbricking phones I ran across on youtube, they have a link to an ebay store (if you search ebay for "Unbrick Service Hard Bricked Samsung Galaxy S4 i337" you'll find them). They are actually a whole lot cheaper than mobiletechvideos, which is one of the reasons I looked into them and also why I'm suspicious. Not to discredit them at all, because I personally don't know what kind of work they do.
I don't even know if Jtag will allow them to fix my build.prop file. The ebay place says if the phone doesn't boot normally after doing a repair, they will restore the latest stock ROM and since i'm on MF3, well... They couldn't do much. It also makes me suspicious that in their ebay description it says:
------------------------------------------------------
By purchasing this auction you agree to the following.
1. Jtag service will avoid your warranty.
2. There is no guaranty 100% to fixed your phone, but we do our best.
3. If the phone can not fix, we will refund only $ 30.00, minus $5.80 for shipping cost.
4. If you claim for any problem after successful unbricked the phone, you need to send it back for inspection. Because we tested it before ship.
-------------------------------------------------------
I mean, some of the wording used makes me uncomfortable... I could just be paranoid, the address on the auction IS Carrollton, Texas after all
Just thought I'd update everyone... never found a fix myself, but I did drive to the next nearest best buy with my phone in the yellow triangle mode and the guy said he knew exactly what to do. He was very friendly, knowledgeable, and helpful... He even knew how to get the phone in download mode We talked a bit, he never asked about what I may have done to the phone, but during our conversation I had told him I had backed everything up and he kind of winked and said he would take care of me. It seemed like he knew what happened, but he didn't say anything, and the "head Samsung rep", his boss was right there talking with us too. He did a full restore, and I was up and running in 10 minutes. If you get a friendly and knowledgeable employee it's pretty painless.

Thanks! I'm really glad to get it back. The road trip was well worth it. My wife and I decided to make a date out of it, we went to a nice restaurant while we were out without the kids, something they wouldn't have enjoyed and we wouldn't normally go to with them

EZ-Unlock Hardbrick [GALAXY S4 | SCH-I545]

I have a Verizon Galaxy S4 rooted, and I heard about this app maybe an hour ago. So I tried it, and it was supposed to be only for S3 I guess. Keep in mind that this attempts to unlock the bootloader on S3 locked bootloaders. It said successful for my phone, so I turned it off. And no sign of life AT ALL. Can't boot into download mode or recovery mode. I really need help guys :crying:

Hooo...oh boy...okay see what you did here, is the one thing you don't do. You know how people say "if theres one thing not to do..."? Well you did it. Not trying to be mean, please don't misunderstand. Just trying to convey the gravity of the mistake.
In all likelihood, it's a paperweight now. Might as well gut it for the parts. As far as I know, there is no coming back from that, at least none that would be cost-effective or even mildly user-friendly.
However, when I screwed my GalaxyS3 as such, I was able to bring it back by booting into a rom on my external sd, but I don't believe the S4's have that functionality. Your best bet, search far and wide for "S4 hardbrick"...but don't hold your breath. We live and we learn.

I guess that's a dead boot. I don't think you can fix this yourself.
You can Google "S4 dead boot" and I think you might find some stuff about it.

Hooo...oh boy...okay see what you did here, is the one thing you don't do. You know how people say "if theres one thing not to do..."? Well you did it. Not trying to be mean, please don't misunderstand. Just trying to convey the gravity of the mistake.
In all likelihood, it's a paperweight now. Might as well gut it for the parts. As far as I know, there is no coming back from that, at least none that would be cost-effective or even mildly user-friendly.
However, when I screwed my GalaxyS3 as such, I was able to bring it back by booting into a rom on my external sd, but I don't believe the S4's have that functionality. Your best bet, search far and wide for "S4 hardbrick"...but don't hold your breath. We live and we learn.

Yeah I saw this video, but the guy only had S3 and S5 debrick images. I'm looking for one right now. And yes I have searched that already. Thank you!

So the device is completely unresponsive from the powered-down state? Try pluggin' it in as-is to a Windows Desktop (or laptop) and see what bubbles popup. If nothing happens...yeah, my sympathies. But if the PC at least notices it, that would mean you're probably in QDL mode, and there may yet be hope. (QDL = Qualcomm Download)

Yeah I guess it's done... I was on 5.0.1 so I have the OF1 version, but the only debrick image for my model number is for the NK1 version. And yes it is completely unresponive. My PC doesn't recognize it at all. Thanks for helping guys. This sucks though

Is the LCD assembly intact? PM me a figure and I may buy it off you lol. My SCH-I545 SGS4 took a tumble and obliterated the screen...this would be my second LCD replacement on it...debating on whether to just let it die or not.

Also I don't know if this means anything, but I have this charging station with USB ports, and a LED showing if it is charging or not, and it lights up when my S4 is plugged in. Does it mean anything?
Would a USB Jig perhaps bump it into download mode? Or is that all part of the bootloader? If the bootloader is dead I think the whole lot is scrap.

Any sign of life from the screen upon doing so? Perhaps, but don't hold your breath or anything. Remember, hope for best but prepare for worst. I'm currently investigating, so stay tuned.

No, there is nothing on the screen no matter what, and yeah I thought of a jig cable, but I've tried to go into download mode before, and there was nothing. And the buttons do work.

Wont boot up after ODIN T-Flash

So I need help. I tried un rooting my s7 edge by flashing the stock files in ODIN, I selected T-Flash in ODIN options because that's what I remembered selecting in the past. Little did I know I forgot to select Re-Partition too. Now my phone shows a black screen, I cant boot into recovery or download mode, but it would seem like the phone isn't shutting off because when I connect it to my PC its immediately recognized and no matter how many button combinations I try it just is disconnected from the PC for about half a second and then re connects. I don't get any response from the phone though. The screen is pitch black and i cant get it to do anything. After flashing I noticed it wasn't booting up at all it was in download mode and when it finished the screen turned black and never came back on. When connected to my PC it is recognized as Qualcomm HS-USB QDLoader 9008 (COM5) in my device manager ODIN Does not recognize it and neither does any other application. Can I please get some help here?
Try pressing and holding the power button until the device shuts off. It could take up to a minute of holding the button down continuously.

Yeah that does nothing. I'm still stuck on the black screen and nothing is happening. I'm about to just sit in a corner and cry. No matter what I try nothing comes on no LED no display no vibrations, all I get is the connection sound on my computer when I connect it that is it it does nothing else.

Try recovery mode:
Hold Vol+, Home, and then Power
From there you should be able to wipe or boot to download mode. Hopefully...

Well like I said before, I don't like giving out directions like I did if I don't recognize the steps to complete it or if others have not supported the validity of it. I don't want to stray you in the wrong direction. The only thing I think you should do, my opinion of course, is attempt to return it under or try to get it repaired under warranty as you don't need insurance as long as you didn't trip Knox, which I don't believe you did.

Okay so i called Samsung and they let me send it in for repair, I'm shipping it out tomorrow. All they asked for was a email my address name and they gave me this code or whatever. I thought I would need like a receipt or something but I guess not. I bought the phone used from Swappa so I thought i'd be screwed. I just hope Knox inst messed up which it shouldn't be because it never was and it failed when I was trying to flash stock firmware. Oh and its free of charge since it hasn't been a year of the phones release yet.

Glad you could get it sorted out. Sucks that it will take a little longer but it's better than attempting to follow complicated tutorials that may not even work and may make the problem worse. Hope they send you a new one, just be careful next time you flash anything. Read the instructions, make sure you understand them and ask about what you don't, then read through again to double check and you shouldn't have any problems.

The only thing I'm worried about is if they call me saying they won't repair it because I have no proof of purchase since I bought it used. I'm so anxious to get my phone back really hoping everything is smooth. It's apparently covered by the 1yr warranty every phone comes with but why would they not ask for a receipt but whatever I just want everything to go smooth.

The Samsung S7's came out in March of this year, so regardless of when you have bought it at this time it's obviously still within the warranty period.

Once the phone has been out over a year where it's not a guarantee that you must have purchased it within the last 12 months then yes, they most likely would ask for a receipt. You're just lucky like that. Lol

Oh wow so its basically just lucky timing, nice. I'm never rooting the phone again all i wanted were better emojis and the note 7 UX and I couldn't even get the Note 7 UX so its not worth it. It's an amazing phone on it's own. I won't ever try and root another Verizon phone there's always little support cause of the bootloader and I always run into something. Glad I dont have to worry much just takes time.

Help! How to fix Hard-Bricked Samsung Galaxy S4?

Hard Bricked Phone: A Phone that won't turn on by any means. Booting to the OS or even opening the Custom/Stock recovery or Download Mode simply won't work.
I've searched plenty of forums regarding Android phones that are "Bricked". But it seems to me that most of the instructions laid out by the "replyer" require the phone to be opened up using special combinations of buttons that would either lead to the Custom/Stock recovery mode or the Download mode which is basically a definition of a "Soft Bricked Phone". A phone wherein it would still turn on and simply has problems with how the OS/Kernel/whatever runs.
Problem: I toyed with my Samsung Galaxy S4 in such a way that it would deal with underclocking my phone. I know that underclocking is a risky thing to do. But I was lowering it to the point where My phone would still run stable... until one day it just suddenly gave out. My phone would still turn on but for about 2 seconds and it would turn itself off immediately. That means that even if i was fast enough to go into the download mode or to my Custom Recovery mode, it would still shut off completely as if I pulled my battery out of my phone.
I'm not really in an INSANE need of help to repair my phone, but a good "Fixing a Hard-Bricked Phone is impossible." or something would definitely help as it would give me a sense of peace around all the threads claiming that they can fix such said phones that are in the same working condition as a brick.
thank you for any help.
:Bump:
Yeah, if the device doesn't turn on through any manner of key press combinations, you're pretty much screwed. I assume when you connect the device to the PC you get nothing?
If I use some type of flashing program from my pc that detects my phone on download mode, it sort off detects it for half to a full second until my phone will give in.
Thanks for the reply.
:Bumping:

friend is totally repairable but you have to disarm and perform jtag will return as magic JTAG samsumg you team only will be damaged the initializer in 95% of cases is so

JTAG? As in that Jtag brick repair where in you disassemble the back part of your phone and you have to connect the Riff/Jtag box to the 6 small pins and use a software on the computer to use the "resurrection" button? . Looking at that process, it does make it possible to unbrick insanely bricked phones. However I do need a device for that and a bit of electronic skills in which I have no background on. Not to mention that buying such device almost costs the same as buying another Samsung galaxy s4 from where I come from. Seems like overkill at this point haha.
Thanks for the reply as it did answer my question, but I think I'll try sticking to other possible alternatives if any. :fingers-crossed:
@gobbler6000: Not to mention owning one of those devices is questionable legality, depending on where you are.
To be honest, after five years, it's not worth trying to resurrect a dead S4. Sell it for parts and purchase a newer device. Used devices should be easy to come by, and I'm sure you could get a good bargain that way.

Thanks! It's the hard and cold truth but I guess s4 is definitely not worth the trouble now. I thought I could probably use my old phone without spending a few bucks. I'll just use my 13 year old appeal and lotsa chores to get my parents' appeal for a new phone.
In one way or another, the questions were answered. How do I lock this thread? :fingers-crossed:

Link seems kinda scammy. It's also of no help to the OP. Besides the fact this thread is from last year, the OP's device was hard-bricked. Your link spends most of its bandwidth on soft-brick solutions, devoting only a single paragraph on hard bricks. That one paragraph on the page can be summed up in two words: you're screwed.
