So you hard bricked, sent for jtag, received working and now won't go into download mode?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I recently went through something similar; I hard bricked my phone (I deleted the check that made sure it was the right phone). I sent it to MobileTechVideos.com for JTag repair and they did a great job and brought the phone back to life (I don't want to sound like an advertisement, but seriously, they were awesome in just about every way).
However, they seemed to just restore it to the last boot-able state. That last state was not completely stable (I had tried installing the rom, then installed Google apps that matched my the rom but not what was originally installed, it booted but apps just didn't work, tried re-installing the rom, noticed that the rom install error'ed out, deleted the check for the correct cell phone, and then bricked it). So when I got the phone back, it was in the state with the bad Google apps; I had to go back and install the correct version.
Long story short, think back to exactly what state the phone was in before it was hard bricked, and try to work backwards from there.

Qhsusb_dload for Tmobile T999 Fix
Hello,
I bricked my phone trying to put the International S4 Revolution rom on it. It had the qhsusb_dload driver request on the computer. It would not power on or connect to the computer. I tried everything and I could not get it into download mode. I tried a usb jig to no avail. After spending 2 nights trying to unbrick my Samsung Galaxy SGH T999 I finally was unable to unbrick it without using Ubuntu or Linux software.
I had trouble with those types of software because I could not fully understand the coding and my computer is a slower laptop from 2007 and it is very laggy and frustrating to use.
To unbrick my phone, I made a image loadable sd card with the debrick image from Tmobile. To do this I used my 16 gb sd card that I kept in my tablet. I copied all of the files off of it to a folder on my desktop and then I deleted everything off of the sd card. Then I quick formated the sd drive. I downloaded the Tmobile Debrick Image' Then I downloaded Win32 Disk Imager. I selected the image file of the debrick image and then selected the drive my sd card was on and then hit write.
I then took the sd card out of my tablet and I put it in my bricked phone. After 3 seconds my phone lit up and went into download mode where I flashed the stock Tmobile rom for my Samsung S3 T999 using Odin 3.07 and voila.. I am back in service. I created this post because I am a novice at this type of thing and none of your forums where able to help me. All of them kept persuading me to send it to JTAG for a fee. People try this first before you pay anyone.

From what i was told the i747 and i747m is the same cause I flashed attroms on it. Did you use the win32diskimager or a linux distro. I think either my sd card is the problem or windows, when i write the img, the sd shows one folder namded "image" with 70 something folders in it.

I used win32diskimager. I got it to work fine for a while, but I couldn't get booted up without the card, no matter how many times I flashed the bootloader. I ended up taking to AT&T, where they gave me a new one because even the JTAG couldn't bring it back. I wish I could be of more assistance, mate.

This gives me hope. My phone randomly hardbricked after flashing CWM from Rom Manager. I flashed it from the app, turned the phone off, and then it wouldn't turn on. I want to try this, does anyone know if this works with the at&t i747? And what debrick image should I use for the at&t version?

Hi,
Thanks for useful post and a description!! When you were turning on the phone with the SD card in which button combination were you pressing:
1) Were you just holding power button for 3 seconds OR
2) Push and release power button and after 3 seconds you see the screen OR
3) You were you pushing a combo: [POWER_BTN] + [HOME] + [VOL_DOWN]?
also where did you get a debrick image?
Please clarify and thanks for help!!

Can’t access to Download Mode or Recovery Mode after bricking AT&T Galaxy S3 i744 4.3
Hi I have (had) a AT&T galaxy S3 i747 with android 4.1.1
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Because the phone is in another country I couldn’t update it by OTA to android 4.3
So I started to read forums that said how to Update AT&T S3 i747 to android 4.3 (I747UCUEMJB)
The S3 was not Root
I installed all the phone drivers in the computer
This is what I did: (http://forum.xda-developers.com/showpost.php?p=52341582&postcount=38)
- Use Odin 3.07
- Check Auto Reboot and Re-Partition, and uncheck all the boxes
- I put my phone in USB debugging in the developer options
- I turned it off
- Started to put the phone on Download Mode pressing volume DW+home+power button at the same time
- In Odin on the PDA box I checked and loaded the file .tar.md5 (I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5 )
- Pressed the button Start
The installation seemed to go right, the program never showed anything weird.
When the Programs finished the installation the phone turned off and then turned on and show the logo of android (seemed to be lying down or inclined) and after that it turned off.
The computer showed that something was connected (QHSUSB_DLOAD) but couldn’t install any driver, so I disconnected it of the computer.
I couldn’t turn on the phone :crying:, I took the battery out and put it in and tried to start the phone and nothing happened, I tried pressing any button to access to recovery o download mode and none of this worked.
I started to search forums that talk about restart or turn on a brick AT&T S3 i747
I found one (http://forum.xda-developers.com/showthread.php?t=2549068) that said to download a image (debrick-SGH-I747U-CUEMJB3.img) and using the program “Win32DiskImager” to put the image inside of a micro SD to make the phone turn on,
I put the micro SD inside the phone and when I pushed the power button for almost 3 seconds it Turned on , the phone seems to be fine an it has android 4.3 (I747UCUEMJB) installed.
I can use it normally so far.
But the problem is that I can’t turn on the phone if the micro SD card is not inserted on the phone.
Without the micro SD inside don’t show any sign of life
When the micro SD is inside I can turn on the phone and use its apps.
I have tried to enter to Recovery mode or Download mode with the micro SD inside but the phone only show what its supposed to happen for 1 second then turns off and then turns on by its own (after that I can use it normally)
Does anyone know how can I Fix my phone ?
How can I boot my phone without using the micro SD card?
How can I access to download mode?
And if I could access to download mode what should I do next ?
The only files I have now are:
Odin3 v3.07
I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5( 905 Mb)
debrick-SGH-I747U-CUEMJB3.img (80 Mb)

hey I'm really stucked, can you please give image loadable sd card because I tried this methode and it didn't worked :/
My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:
Have you installed the LG drivers for your pc and tried the unbrick method?
Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660
There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.
Okay

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned.

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .
Thanks

Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660

I have tried this and unfortunately since the USB drivers aren't detected by the computer there is no way for me to flash back to stock.
Thanks for the information though, I appreciate it.

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.
Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Just wrote it to sd card

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.
Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.
that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.
What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?
+1
Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.
I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.
Hi all,
I got given this Tab3 because the smd power socket connection guts were physically broken inside socket.
Fitted new power socket (I'm an electronics repair engineer by trade) and checked all pcb (printed circuit board) tracks leading from new fitted socket to ensure there were no hidden breaks ...... new socket refit was 100% successful .....with no solder shorts / bridges and no broken tracks leading to mainboard.
I left Tab3 on charge overnight and next day switched Tab3 on only to be greeted with dreaded .PBL and .PIT failed issue.
After extensive (days!) research I gathered together all necessary firmware and tools and decided that its an easy firmware fix if flashed to an original Samsung SM-T210 UK firmware.
(Please note I dont know past history of this Tab3 .... I dont know if it was rooted / upgraded firmware etc ..... I doubt it though as it belonged to a 7 year old)
Big issue ..... Odin flash tool won't show coms port connection on PC via USB (have tried 3 different laptops one with XP, one with Win7 32bit and another with Win7 64 bit. I've installed / uninstalled / reinstalled multiple Samsung usb drivers that were verified to work with my Tab3 SM-T210 model on each PC .... no joy. Even installed / uninstalled / reinstalled Kies from Samsung .... still wont connect when Tab3 is in download mode. Have kept PC device manager open and nothing appears in device manager. Also have tried 6 different makes of Usb A to micro Usb cables. Have disabled all antivirus, UAC, firewall and Win defender etc ... still no go!
When I go into download mode (power + Vol- +Home buttons) a warning screen does appear BUT it only shows right hand side of graphic warning ..... left hand side is totally grey from top to bottom. (LCD screen is not faulty as it displays full screen info on failed .pbl / .pit flash memory checks) When I then select Vol+ this vertical half graphic info and half grey screen disappears just leaving the backlight on .... which I assume means Tab3 is in proper download mode?
I can go to all recovery modes which allows me to factory reset and delete user cache etc .... it seems to go through the proper routines of reset but upon restart .pbl and .pit failed error in red memory check list is still there.
I can also try and flash firmware file from external sd micro card .... Tab 3 recognises firmware OK and shows Install ..../SD, but then after approx 5 minutes it restarts to failed .pbl /.pit error list again.
Apologies for long post, but from reading above issues can anyone please confirm ....
1) Is half graphic normal when going into download mode? .... or does this point to a previous incorrect or unfinished flash issue?
2) I have downloaded proper .pit flash (LT02) file and original firmware flash for my Tab3 ..... can I flash this any other way other than using Odin ....eg is there any bdm flash method (direct hard wired) flash method to motherboard from external programmer ....like they use for car ecu flash recovery?
3) As I dont know exactly whether Tab3 was rooted / flashed with wrong firmware / incomplete flash upgrade, is there a software tool that can attempt to list what firmware is on my Tab3 at present?
4) I can get into ADB recovery within recovery mode but havent a clue how to use this method .... is this a possible recovery method to use, as I can see SMT210 ADB device in PC device manager when going into recovery mode?
many thanks in advance for help, :good:
Tab3SMD
OK all, here's more info .......AND another additional issue!
I got stuck back in again tonight because not knowing anything about Tab3 ADB recovery mode was bugging me, so here's what extra I've done so far
While "poking my nose" into tonnes more Xda forum troubleshooting guides I discovered I might need PitMagic tool to try and sort my .Pit partition error via ADB recovery mode.
I tried to find Pitmagic but discovered this is now part of EFS Professional, so downloaded EFS Pro and found this got me nowhere as I needed to also install Android SDK .... which also requires Java Development kit, so I downloaded the full Android Studio and Java JDK 8u91 and installed all (about 1.2Gb and requires ~ 4.2Gb hard drive space!)
Anyway, I now ran Android Studio and then ran EFS Professional, opened my Tab3 into ADB recovery mode and connected Tab3 and PC via usb .....
All looking good EFS reported
Initialising ADB server ..... Okay.
ADB server is running!
Searching for device..... OK
Connecting to device .....OK
Checking device status .....
THEN BAMMMM ....popup from EFS
Connected device is currently UNKNOWN
Please ensure ADB server has been authorised by the connected device by confirming your PC's RSA fingerprint, then press OK to continue
like, wtf! .... one step forward and 6 back!
Can anyone please tell me what this means or better still how to proceed from here?
Anyone?
Anyone??? .....Tab3 is still soft-bricked
I did figure out how to use ADB flash recovery mode using PC.
Unfortunately this also did not allow me to flash any firmware (original or custom) due to admin permissions
(I think this is due to USB debugging not activated within Developer options).
I'm sorta banging my head off the wall with this one .... a bit like what came first? egg or chicken?, because since Odin isn't being recognised by the PC, I cannot flash rom and even though the PC fully communicates with Tab 3 in ADB mode, it won't allow me permission to sideload any flash files because I reckon I need root based permissions, and since the darn thing isn't booting fully, I cannot manually change anything!
I then started thinking about trying to sneak around this permissions issue by flashing CWM or TWRP, but again flash fails due to no permission.
All in all, for me this has been a great learning experience tackling the multiple Android recovery modes, and since I feel so close to cracking this non boot issue, I hate to give up and bin it.
Perhaps someone with much more experience can please help me here?
Is there any way of forcing superuser status on this Tab 3 SM-T210, so as to allow me to flash stock rom via ADB recovery mode?
many thanks in advance for your help,
Tab3SMD

Hi guys,
i need some help unbricking my d722.
what went wrong?
I tried to flash twrp with flashify and i ended up in demigodmode.
from there i connected the phone to my computer and like 10 portable drives showed up asking to be formatted. I formatted all except one drive because it was protected from.
After i formatted the drives my phone was dead with only a black screen left.
Since i can't find any .tot firmware files for this model i tried to use the .tot firmware for a g3 in BoardDiag.
but when i want to use the extracted .tot firmware files on my phone it says this:
no response from device, check pmic first and if still boot problem replace ap
i think i have managed to install qualcomm driver and the phone is recognized as a qualcomm when plugged in.
But i did not shortwire the motherboard because i can't find the GND
can anyone please help me fix my phone thank you so much!
I have been following this forum for years and thanks to all the geniuses here through their guides I have always managed to make all the modding I needed.
But not this time, I'm going crazy.
As the title suggests I have a Samsung Galaxy Tab S3 SM- T825 Qualcomm MSM8996 Snapdragon 820 to which I want to root by mounting twrp recovery and magisck.
I've been trying for days but to no avail.
I state that I have adb fastboot odin latest versions, updated drivers etc.
The problem that occurs is this, adb recognizes the device in normal mode.
I flash twrp and everything is fine I go to twrp, I do the steps of ext2 ext4 file system otherwise it will not read the data and again, all is ok.
But as soon as I reconnect the tablet to the usb cable for adb sideload, my windows 10 no longer reads the device, it does not even emit the classic usb sound ... So it does not read it or adb of course, but neither does the pc.
Just flash with odin rom stock android 9 pie, review the tablet both pc and adb again.
Obviously all the procedures with oem unlocked and usb debugging active in file transfer mode.
I've been going crazy for six days to complete the operation, but I can't ....
I have no idea how many guides, tutorials, videos, possible resolutions I have consulted and applied but to no avail
Can someone please help me sort out or figure out what the hell is wrong ...?
I'm about to set fire to my tablet and pc ....
Thanks in advance and sorry for the not perfect English
