Hardbricked Galaxy W

I know that my current question will be so funny. But is there any chances to revive a hardbricked Galaxy W? I saw some post said that they can revive their bricked phone, but without any detailed information

Unless you can the device is under any of the status below:
1. Still can be on, and bootable to either CWM or Download mode. (flash in stock rom using odin)
2. Power port failure, unable to charge battery at all phone cannot be on due to battery being empty completely. (send to ssc if warranty still present or use external charger like multi pin supporters).
3. Battery issue, battery is dead. (get a new battery).
Or else, if warranty is present, send to ssc, in all odds they should not detect a rooted phone because all available interfaces are hidden.
Or else, send to local phone repair shop or ssc if they provide phone repairs and see if the price to repair it is worth it and try fixing it.
(in my country, likely the price is insane )
Lastly, to the trash it goes.
Click thanks if suggestion or solution is found useful

Ssc if you still have warranty

i747 Hard Bricked: QHSUSB - DLOAD : Needing a debrick.img

SGH-I747 (4.1.2 i747's please)/ SGH-i747m( If you have a official 4.3 i747m, please post a debrick.img) only:
Hi, I recently hard bricked my phone into QHSUSB DLOAD and I am going to attempt repairing it through the SD Card boot method.
http://forum.xda-developers.com/editpost.php?do=editpost&p=47431259
I need a debrick.img to flash to the SD card in a Linux OS.
I would have gotten it myself but my phone is obviously dead. I found one before on XDA, but it did not work on my device and it gave me an error in the Linux terminal when it should not have.
-snip-
The end of the 3rd boot-loader stage in mmcblk0 is at 77.3 megabytes. If you are going to help out using your device, try to refrain from uploading an image with a different ROM other than root.
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/backup.img bs=2m count=81054925
The count is the amount of bytes. I am not sure if it is meant to be 1000 bytes=kilobyte or 1024 bytes=kilobyte. The count above is for 1024.
I need someone to install the Galaxy S III unified toolkit, and pull the first 7 partitions from mmcblk0 ,which is where the third bootloader stage ends.(Don't upload a heavily modified device please) http://www.skipsoft.net/?page_id=213 Once you get the files, PM me.
If anyone has a link to a working one, please post that. If you want to get your own image to help me, go ahead.
Thanks guys.

Sorry for the bump... I just need the device running again since the state it's in, it CAN be unbricked.

I tried to unlock what I thought was a locked bootloader(I could only enter bootloader through ADB)
I found an article that says ezunlock works on all S III's.
It corrupted my bootloader,and my phone gives off no signs of life except "Device QHSUSB-DLOAD not recognized" when plugged in.
This means the motherboard/processor wasn't able to boot from the hard disk, so then it tries the SDcard if it matches the phone close enough.
I need someone to use their rooted i747 to dump the first 77.3 megabytes of "mmcblk0". That contains the firmware and bootloaders. With that, i can burn it to an sdcard in a linux operating system and plug it into my phone.

Thanks for that link! It looks very promising, and I can probably find a stock boot.IMG in there. I will work on tomorrow. If I succeed, I'll edit the OP and make a debrick guide for this drvice forum. A word of advice, try not to mess with your bootloader or you end up like me

Hi, the toolkit didn't fix my phone, but its defiantly a step up. Since I'm assuming you have the toolkit installed that you suggested it, could you do me a favor?
It will be a bit easier using the toolkit to extract the partition files. If you could pull the first 7 partitions from "mmcblk0" of your device through the toolkit, it will probably set the next step to fix my phone. (Assuming you have a 16g i747... I don't really know)
You don't have to do this of course.
Thanks man.

Bump. Can anyone help out? All I need is the first 7 partitions.

either try using this link http://forum.xda-developers.com/showpost.php?p=27239761 am pretty sure it works for all S3 models, either way on the I747 forum it has been removed, the download link does not work........ so use this
it will work, it may not work but for the time being use this toolkit and also search forums or Google on how to fix this without, i think i found some answers after i had an emmc brick with my S2 but i did not have an SD card to re-write firmware to work again on my phone so i bought the S3 and its awesome

Did you use an i747 or a i747m device?
If a i747m image works on an i747, it will basically fix all of my problems.

What message appears on your computer when you plug it in?
If it says QHSUSB-DLOAD, you are in faint light.
It stands for Qualcomm High Speed USD Download Mode.
What is means that your processor(qualcomm), is trying to boot, but it cannot find proper drivers for the hardware.
It will then look for something to boot from in the SDcard.
Here is a thread on how some other people were able to do it : http://forum.xda-developers.com/showthread.php?t=2439367

I have an I747M technically. I went for an actual I747M image just in case there was a slight difference. in the thread that one came from though there should be one for the actual att device if you look through it.
and just to confirm, yes the phone was blank and unresponsive. showing up as QHSUSB-DLOAD before i loaded that img onto my external SDcard. and I am using the same phone currently.

Unfortunately that's the download I found that didn't work.
Thanks for trying though

damn! the only other help I can offer then, is that there is a pretty good thread on this over in the d2tmo section. someone there wrote a little tool to easily download the relevant data. might help you on your quest. or at least make it so you could ask someone that doesnt know ADB. best of luck!

OK , take out your battery and tell me your model number(Behind battery). And what phone company do you use?
Did you possibly save a NANDROID on a computer?

You need to install a Linux operating system (Ubuntu works) to run the commands.
Edit:! According to the T-Mobile thread, you might need a debrick.IMG from a phone on 4.3
Once I know your phones model number, I can edit the main post and ask for you phone model's images.

yes, take him outside and beat the crap out of him. Then take his money and go get a new phone.
Other than that, I don't know.

No I cannot, my friend(parklane79) and I actually found a method, it seems promising but i need to try it out first.
im not afforded the link rights yet but the title is "Fixing a bootloader-bricked Galaxy S3 using an SD card (Qualcomm SGS3 variants)" and a more simpler guide for n00bs(although not a complete n00b been doing this for a few years now :good: ) like myself, "[GUIDE]Unbrick a Hard Bricked SPRINT Galaxy S3 (Without JTAG)" but for the second guide you need to grab the i747 debrick.img off the first page of the first guide.

Yea tried with a class 10 16g micro sd like a million times and it wont work.and i think its because i dont have the 4.4.2 img if some one could help me out by uploading it. u et the img via busybox dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1M count=70

So the phone won't power on at all? Can't get into download or recovery?

are you %100 certain it's the AT&T 4.3 debrick.img? did you put it on the SD card using win32diskimager?

im 100% sure. the issue is tho that i was on 4.4.2 and dont know it an i747(AT&T) 4.3 debrick.img has the same handshake/protocol whatever you want to call it as a 4.4.2 debrick.img I tried it out tho anyways. but in short yes im 100% sure it was a 4.3 debrick img. And yes I did use win32diskimager. I tried once on linux mint but i believe the file corrupted so i just ended up using win32DM. I mean they are supposed to do the same thing, if im not mistaken

Then you should be able to use a debrick.img. are you using an sd card the same size as your phone's internal memory? if you had it on 4.4.2 then you might need a debrick.img from someone with the same phone on the same network running 4.4.2?

sounds like you're stuck until you get that .img file. If you know someone with the same phone you could maybe get them to install 4.4.2 and get the file from them? otherwise keep asking around or wait until 4.4.2 is released for the s3, which might take a while.

I did, it was on CM 10.2 when i had flashed improper bootloaders and bricked it. I used the sd card to install 4.3, unroot+ reset flash counter then took it out so it went back to bricked. My only fear is that they may some how get it into download mode instead of just replacing the board and see the warranty bit: 1 which isnt able to be reset as it is an e-fuse which is blown when you install firmware without knox.

im sending in it through bell mobility. it was a replacement phone that i paid the $150 deductable on and has a 90 warranty. I said it was having issues/defective so they sent an s4 as free replacement on the 90 day. I prefer it to be bricked to fit the defective description as well as to decrease the chances of them finding out i had messed with it, the only real sign being "warranty bit: 1" in red on the download screen. I did use odin to flash the current 4.3 stock that it has right now, and i might be able to get it to boot without the card if i flash the bootloaders some more despite having done it twice and the card still being required. Like i said though, i prefer it hard bricked and i've erased every sign other than warranty bit: 1 that i messed with it by installing stock, unrooting, and resetting flash counter.

bricked my i747. calling all pros

Hello people, I randomly tried to flash internation model rom on my i747 model s3
it gave wrong model error so i went and modified asserts in the update file and made it pass the check. but phone wont turn on now. i do get red led when charging it. I know it sounds stupid but i just wanted to give a try (was assuming I would unlock the phone :laugh
anyways i do know that 16gb sd un-brick method. but i was wondering if there's a possible different method.
thanks for your time.

Only paying for a jtag service

looks like SD Unbrick method isn't working either, it's not turning on with unbrick sd. i did do a backup before all this. can anyone help here?

Dont give up. Many people have to run through the sd creation process several times before it worked.
It could also be the sd card you are using.

the thing is, all debrick img's posted on threads are for 4.3 and up. my phone was on 4.1.2 with an i747 bootloader.
going to order a usb jig (since diy's failed)

If you are on pre-4.3 firmware, it shouldn't matter what debrick.img you use. But if you do get it to boot it will not let you flash anything older than what the image is.

Of course it wouldn't hurt to have a 4.1.2 image.....

It is a good idea to have a jig handy. But you many not even need it for that one. The exact same thing happened to me (I747m - Fido).
Just make sure the SD card is the same size as your phone for the image.
I am assuming you already found all the steps? You can pm me if you need the necessary files.

I have tried many many debirck img's. both for t999 and i747, for 4.3 and whatnot. today i got the jig in the mail but the try failed, still wont turn on. i lost hope and i feel like sending it to ebay service is my only resort. the sd card i was using was a pixar class 10 16GB. idk what would go wrong with that.
the reason that i bricked it, again, is flashing wrong bootloader.
any help would be appreciated.

Idk bro the international s3 is a whole nother phone, it has a quad core exynos processor while we got a dual core snapdragon, it's got a gig of ram we got 2.... That's too name a few differences.....I think the only way to fix it is by a JTAG.......sorry bout the luck bro

O don't think he's got an international version. Thought he mentioned having an I747 before??

If you don't mind shipping to Canada I have a riffbox and could fix the issue for you.

The debrick method should work though. If it were me I wouldn't give up just yet. I'd at least try a few more times on every sdcard I could get a hold of. Often doesn't work on the first couple of tries, and AFAIK there's no way to know which sdcards will or won't work. Just gotta keep trying.
It is possible that for some reason this method simply won't work, but it has worked in the past for similar types of bricks.

[CLOSED][ANY BL locked G4]need testers [follow the new thread!]

First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
Please follow the story here now:
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
Previously this was the OP:
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)

Super excited about the possible G4 unlock! Wish I could test it but my phone is my daily driver and my source of internet at home so if it breaks, I'm screwed for my online classes. Thanks for your hard work as always!

Good luck to the testers, we're all rooting for an unlocked H818p Brazil.

It happened to mine 818p too, you need to disasseble it and short two pins on the motherboard while starting it. (They are in the upper left corner on the MB.) This page (forum.gsmhosting.com/vbb/f779/unbrick-lg-g4-brick-hs-usb-qdloader-9008-without-box-2211744/) has the entire process explained but I was unable to sucessfully use the QFIL app, it didnt recover anything, at least the phone was seen on PC as the 9008 serial port. I hope it helps
P.S: Sorry for my bad english.

i hope you get it going man. so lots of users can enjoy this device like it should be.. youll be saving LG G4.. am glad that what i mentioned you got your brain thinking and finding ways i beleive this all was what i mention on fish. good luck to all of you.:fingers-crossed:

Yea i still used it for about 6 months. Put the fish to her. Even still vred with thr cracked screen. Like i said. Went to check the time and nothin. So im assuming shes dead. Ive done got a g5.no root and no twrp. Yea. Just the way i like it. I know i know. If i wanted root i shoulda bought an unlockable model. But i take what i can get cheap. Bought my sprint g5 for 25 bucks at a police auction

Hi, I have the model H815T but... now it Hard Bricked haha. Anyway, I can boot it like LS991 model (with QFIL), and Download Mode it's working too. So... is useful for your method?

Now out of curiosity would a bootlooped g4 work. Most of em boot into dl mode and if it bricks dl modde youd know rite away anyways right?

Qcom 9008 mode? It could be fixed afaik.. You can also try the sdcard boot method for this kind of brick. you should try that first in any case..
I'm not sure if my method will work in that kind of brick mode you are in but if you nevertheless want to test you need Linux / best is using FWUL because it has everything needed inside.
Once ready went to IRC on Mo-Fr and stay until Im there.

it depends. When it stays in download mode without looping.. yes - maybe!
I need access to to the partitions which may work even in download mode via a special shell but it may requires MM and will not work for LL firmware (strange right? normally one would expect the other way around..).
That has to be tested though. On my device (locked H815) I had access but that may differ from other models.
Having root access makes things so much more easier
Testing if it would be possible on a bootlooping device would be simple:
You best use FWUL (recommended because here is all installed and working) or any other Linux with the LGLaf shell.
You would then connect while in download mode and you will have a shell like in adb.
I can guide you but again IRC is the best way to go here..
I'm searching since several days for such looping and even otherwise broken/defect devices but they all want to have a plenty of money for it (80-150 €!!)

Yes, QCOM 9008 mode. I can't flash the H815 image and make my G4 H815 again so, the only way to booting, it's flashing the LS991 image (and with Fastboot; I flashing every partition one by one).
I have Linux Mint whit adb/fastboot drivers, It's enough?

Hmm I can't help you unbricking. I just know that there are ways to do so. You need the correct drivers etc.. But well if you tried all this already we can try
Any Linux is ok as long as you can handle it
Havin TeamViewer installed may help too...
Well so if you like go to IRC Monday to Friday and we will see

Yes. today I have bad and good news.
First of all I had 1 single tester who was brave enough going the first approach I had. Unfortunately my first idea failed.
JL if you see this come back I said I can unbrick your device!!!
Ok so the good news are: I'm able to give you a near unlocked experience with all the things you love like installing custom kernel, recovery and ROM. Without actually unlocking!!! It's all tested on a h815 device which was never unlocked !
Near unlocked means it will behave like an unlocked device without actually unlocking the bootloader. Or to say it in other words: The boot chain verification is ignored.
The bad news: the process is not cleaned out yet but it requires one thing for sure: it will convert your whole device bootloader stack. The basic idea is to replace the whole bootloader stack with a modified one which allows all the mentioned things.
That way is very risky and I HARD bricked my device over 30 times until getting to the finally working result.
It also means that once your device is converted there is no way back atm. Flashing an original kdz will BRICK your device in 9008 mode! Not that bad because you can recover at any time but that's one thing you have to have in mind. It may never be a h811, h812..... whatever again. Until we find a corresponding and working bootloader replacement which may never happen. So no LG up or LG flash tools anymore! Instead you will have the qfil tool.
Again I know no way back to original state so warranty will be very very likely refused once you do this. Ok there is a way to blank out all partitions just for the case you need to send it really back. This should delete then most traces of this hack but no guarantees.
Besides this I don't know if there are any issues in functionality after doing all this. I havent made any tests for this yet. That includes phone calls, WiFi etc. I just checked booting ROM, booting TWRP, flashing supersu, getting root.
I will upload a video asap to show you the current result.
I need to test things further and of course I need testers with other devices. Again that process is risky and even if it worked for me it may not work for you (very unlikely but who knows). Manually forcing the 9008 is very easy and it may be required to do so. This may requires opening the device (I think it will work even without but I need testers.. ) so if you want to test... See you in the IRC.
If all this is working and verified by others I will provide the whole story ofc!
....can't believe that all these above took me 5 days in full time of work. And for what? I mean I do not need it because I can unlock my device OFFICIALLY..
BUT it was all for educational learning. I learned really a LOT of android and qcom during all these hours ...
Ok but Now I need some couple of hours of sleep
See u on the other site..

so........what now ? i have a F500k device . and i'm willing to test your method . but i'm not sure what you are saying here. ( i didn't understand a single word) . but if it means that i can't flash official KDZ or can't use LGUP....no problem to me.
just share to me how i'll do it and if i hardbrick how i'll restore it. thats all.
