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

What exactly did you do to your phone?

if i remember correctly he flashed the swap partition script from another thread.or is it someone else..sorry if im wrong.

Swapper SD, I think
A Hackin' ROM!

my friend here in the philippines,, successfully revived a Samsung Galaxy S1 using a usb jig,,
the phone isnt booting at all,, meaning ,, no recovery ,, no download mode..
though dont know whats that for,,,

[Q] Galaxy Note II N7100 Bricked, Cannot enter download mode, USB JIG not helping

I used heimdall to flash stock rom (extracted the varios bin and img files from N7100XXDMB2_N7100OXEDMC2_SER), and missed out sboot and recovery. Once it finished, I tried restarting the phone -> and it wouldn't do anything. Now I cant enter the download mode.
I tried a home-made USB JIG (300k ohms b/w pin 4 (the left out pin) and pin 5 (ground)), and it wouldn't kick the download mode either (does nothing).
I am seriously stuck and have no clue on what to do. If it helps, when I try to boot (with any combination of keys), the indicator (left) blinks red once.
Begging for help right now... Please tell me what to do. I love my phone, and I have a decent understanding of Computers/Electronics - so it's okay if you go all technical

More Info:
Extra Info: Verified that the USB JIG is doing the same thing, i.e after 3 seconds or so, the indicator blinks red... (and so on after every 5 seconds in a loop thereafter).

Good chance of SDS

You have messed up bootloader so won't get download mode
But if you have heimdall and some techy here is guide to flash bootloader blindly, if you succeed to flash it, you will get download mode and subsequently use odin to flash stock rom

I have never actually used jtag to debug anything! Is it worth buying one just for this purpose? Also, I'm not able to find any wiki on how to use jtag specially to download a particular bootloader (Learning JTAG and its usage as a whole seems very tedious)...

You have to attach the wires directly to the nand or internal memory chip or whatever it is(could be memory controller if there is any). Then you have to connect it to a box? I don't know much about it. You can check on the internet. You have to flash sboot.bin I guess

On a side note (not sure if I am violating forum policies), I am still within warranty period - is there a way Samsung can pinpoint what caused this? Or can I still get it repaired with some generic reasons?

Well if it were sds or it's symptoms then yeah.
But you could try maybe they would just consider it sds or something else.
And don't worry. Talking about Samsung isn't against the forum rules

Best answer if samsung guys ask you, tell them it was happened when I got OTA and after getting update device never started, there are cases reported bootloader can't update while on ota and device fail to boot further.
Just don't show them you are technically sound, and behave like noob, they will install it with jtag.

Thanks for those suggestions I will try my luck at this tomorrow. Looks like whether I get it repaired free or not, I can't use my phone for a couple of weeks
Thanks again guys! Really appreciate it!

If it is just sw issue, you will get back in few hrs,(basically it takes same time like we flashing with odin, few minutes) and under warranty you should get it free.

Plz help me unbrick my hard bricked phone

I wouldn't recommend it. Please go to a gsm service.they will fix it.If you are not a tech wizzard,then don't try to recover a hard brick phone home.there are alot of command lines to be written and the most slightest mistake will result in a permanent brick,beyond repair.You have 2 choices : send the phone to warranty,tell them it died.Go to a service and pay about 20 bucks to repair it.

No other way really ?:crying:

I am also facing cookie not received error on QPST. But my phone is Cherry Flare, qualcomm msm8225 based.
I had updated my phone to Jelly Bean (used it for 3 days) which died while it was charging. I tried to flash bootloader through QPST, but got the cookie error. I assume the QPST can solve the flash problem if something went wrong while updating firmware. In my case I was not updating the firmware, it suddenly died. After reading so many forums, I could not find any solution and am thinking that the phone is beyond repair by myself.
Now my question:
1. Can service center repair the phone through JTAG? I believe JTAG can directly access eMMC flash which QPST could not.
2. If not, can eMMC be replaced? Or the entire main board needs to be changed?

If the emmc is intact,jtag can fix it.
If the emmc buffer is corrupted or full with bad attempts to recover,the only way is to change the mainboard.
Happend to a friend with a galaxy note.he tried so many times to fix it with odin home until it was too late for jtag.it could't acces the emmc.
Anyway,if the phone is hard bricked,it can't be traced.so send it to warranty.

Brick problem (boot certification verify)

Ok so I have this issue with my phone.
I tried bringing it back by using the KDZ programm but everytime I try it I have a problem with the extraction of the file.
I tried the compatability issues but it doesn't seem to work.
Please could somebody say to me what to do?
I need the phone for tommorow and I made a fuss and trying to find a solution. If I hard reset it will it start?
Thank you in advance!
Ok so I tried to hard reset it but it pops out the same message.
What am I supposed to do please give me some feedback.

It is software brick. I updated it today, it tryed to restart and it couldn't do it!

I managed to unbrick my device but it seems that it doesn't have the root inside it.I tried to root it again and it says that the binary support is missing.Any ideas?

wow,i'm still amazed. please,don't ask for support on PM. it's one thing i'll never do, at least not for free.
you have all the info you need here.if you can't find it,well, look further.
like i said, clicking on my signature will give you alot of answers. if you still can't fix it, it means you don't have the proper knowledge and it would be better to call someone who has it or start learning.
I always advice users to document themselves BEFORE,not after screwing up.

Ok we got your point.... You say some things, I tried some things and they didn't seem to work cause I didn't knew what the problem was... You know what... You can also block me from your pm and looking at my posts, and don't whine for it here like a baby.

I'm whining?If you only could see how many PM's i'm getting..you wouldn't say that. And most of those questions have been answered here,including by me.
Bottom line, use either kdz updater or lg mobile tool(for emergency firmware recovery) to get a clean phone,then start rooting and unlocking procedures.

Ok I am sorry ok? But you seem to be the only one knowing things about this phone so expect pm's... If I update it through the LG tool will my stuff (apps etc) will also get erased? Cause I can't back up them.If I remember right titanium backup works only with rooted devices.
Sent from my LG-E975 using xda premium

You can try other methods to root. There are several ways. Again,my FAQ can help you.
I get you don't have a custom recovery,right?since you lost root and you didn't unlocked the bootloader.
And there is an app called hellium,developed by cm team if i'm not mistaking,which allows you to backup your apps without root.

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.

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.

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.

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!

Once I know your phones model number, I can edit the main post and ask for you phone model's images.
