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.

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.

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.

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!

Roms for AT&T V495?

Are there any working ROMs or even recovery for the G Pad F 8 (V495)?
Sent from my Nexus 6 using XDA Free mobile app

Not at this moment. We need more people to be interested in such.
Fortunately, there's a recovery for the V496 (T-Mobile variant).
We need testing for the v495.
Look here.. Make sure to back up your exisiting recovery. Then flash this. If it works, make sure to reply here or at the other thread. If not, still let us know.
In the event we ever get roms, you wont be able to flash anything for a specific device that isn't v496. Atleast until someone rebuilds the recovery for your device.
In any event. I would like you to contact me so that I can walk you through a dump of all of your devices partitions, except the personal ones.

i guess it is a start, as there has been no info on these tablets. i have one and really like it, but it would be nice to get rid of all the att bloatware. i have it unlocked and am using defense mobile for carrier but i cannot use it to tether or hotspot. looking forward to more info.

I have this device for US Cellular. I would really love to install CM rom on it. From my understanding the two problems are the locked bootloader that prevent us from installing a rom, and also there being no ROMs that support our version.

Specifically, a locked bootloader also makes it either impossible or extremely difficult to have root, too, which of course is a prerequisite for installing anything custom.

Also to mention that you can root it with Kingroot but there is a good chance it will also brick it. I have v495 sitting here waiting for a proper KDZ.
I keep searching everyday hoping I see a KDZ pop up. Nothing as of yet. I just bought an nVidia K1 Shield to use in place of this thing for now. Maybe one day I will get it back working.

King root 4.6.2 will give you root on marshmallow but only till you reboot.. Would be happy to help out in the cause.

Hello!
After unsuccessful firmware, I had the same problem as badvs3vil https://forum.xda-developers.com/showpost.php?p=67942420&postcount=29 blurred / damaged video screen.
I was flashing firmware from LG V490 using LGFlashTool2014.
As a result, immediately after the end of the firmware, stripes appeared on the tablet screen, and nothing was visible :crying:
There are sounds of charging, the tablet responds to touch.
Please help restore the tablet!

You can install LG-AK495 to fix it.

So, I guess there's no custom roms for this thing, huh? That's a shame. The thing is super slow and running Android 6 with AT&T bloatware

[Q] ATT ZE500CL/Z00D Bricked After OTA Update - HELP (ZenFone 2E)

I have an ATT ZenFone 2E that I rooted successfully with this guide (http://forum.xda-developers.com/showthread.php?t=3116531). Due to an error on my part(fat finger) I accidentally started the OTA update. Now when I try to boot the phone all I get is the AT&T logo/splash screen. I can get it to go into recovery mode and it also will connect via ADB. I have tried flashing the UL-ASUS_Z00D-WW-12.16.5.30-user.zip firmware via ADB fastboot but I get an error saying firmware is wrong carrier ATT (WW). Am I using the wrong firmware for AT&T? I have searched all over and cannot find any ZenFone 2 firmware other than WW, TW, and CN. Any help or suggestions much appreciated.

Still no luck. I'm sure if we could find the AT&T firmware we would be able to recover. Unfortunately it appears it is not available on ASUS support and AT&T doesn't even provide firmware. Our only hope may be from a backup of another device that isn't bricked.
Does anybody know if we could possibly use the temporary CWM recovery used in the root method to flash to another ROM that is compatible with this device? Any input would be greatly appreciated.

Are there any details I can provide that would be helpful in finding a solution to recover this device? I've seen a few other people are having the same issue as I am and I would like to help them as well if I can get mine fixed. Thanks

Just out of curiosity have you tried running the xoa_unroot.bat while your device is in recovery/fastboot mode? Im not sure if it will help but I've found in other threads that to avoid soft bricking your device you must run the unroot prior to applying the OTA update. I'm sure it's probably too late but maybe worth a shot. I'm going to try it when I get home from work today.

Wait, are you bricked and tried using that as the fix? I cant post links but Check out Asus, They have Firmware, Kernel (havent checked but read it earlier today), and Boot Unlock that you can get right from (assuming you have an account) My Products.
Also... Has anyone used that method recently?
Cathaterfish said:
Sorry I will give credit to DavePmer for his guide in minute, but qouting him for some reason wouldnt let me post, even when I removed the links? anyways I'll edit and give credit I promise
So my phone is stuck on the Asus Logo, I downloaded all of this and followed the instructions all the way up to:
11) now the fun part. open your microsd card and check the folder TWRP\BACKUPS see if it has a folder named
01234567890123456789 if it does great if not, not a problem just copy all the system files from the folder
you extracted TWRP-zf2e-ATT_12.16.10.7 to your microsd card TWRP\BACKUP\01234567890123456789\ whatever folder you have next\ in other words, replace your system.ext4.win000 files with my system.ext4.win000 file.
Replace your system.ext4.win001 with mine, and replace system.ext4.win00.md5 with mine as well as system.ext4.win001.md5 when done safely dismount the microsd card.
It then occurred to me that i should be more careful this time around... This was from October and although I ran across links saying for the most part that this was a good shot for fixing my ZE500CL, Z00D or whatever. But things have changed since then and I was wondering if this is still the best/easiest/safe route. I learned pretty quick that over looking things like OTA/Root or in my case Making assumptions is a fast path to really doing a number on your phone. (Honestly I just started even giving thought to rooting my phone, just considered them back ups I kept in a box). I now have the itch to do this right so hoping to fix this and go about this the right way.
Thanks for any input.
Currently DLing RussaiNBeaR, went and bought a card reader/writer. I was going to Download the firmware, kernel and boot unlock tool but currently staying at a place where im getting 160kbs on my DL's. So if I can get away with davepmer's guide that would be great, or something other or smaller than downloading 4gbs on this Internet Connection.
EDIT: Forgot to add that I haven't completed this step yet because the wording kind of tripped me up. And I want to do this right. When he says "in other words replace your system.ext4.win000 files with my system.ext4.win000 file." and then goes on and 3 more to the list. Does that mean only copy and replace those 4? or does that include all system.(whatever).(extension) files? Im sure it sounds really dumb or noobish but the fact that the next step is using twrp to restore using system only makes me afraid to do this part wrong.

ATT ZE500CL/Z00D rom

Looking to be pointed in the direction of a root for Galaxy Tab A6 sm-t280

Hey guys,
Been searching for a few days now ive tried several root methods
the ones from playstore like
Kingroot
Kingoroot
Kingoroot desktop
Its a galaxy tab a6 running android 5.1.1
Build number LMY47V.T280XXU0APB6
All of the above say they can root it but they all failed
I have seen posts on forums such as this one offering custom roms for the device so I must assume there is a root somewhere and I just cant find it.
Any help would be extremely apreceated

Nope, no root for this device until an exploit is found.
Where is this custom rom you speak of?

I've tried everything possible so far to obtain root.
Hopefully eventually one of the apps like Kingroot will work.
Why the heck Samsung locked the bootloader on this device I have no bloomin idea!

Me either no contactless pay as no cellular so why ?
I got mine direct from Samsung and the bloat is horrific
8gb model and over half of it is unusable and without a root an sd card isent really much help
In essence I have gta sa installed and can't put anything else on its infuriating!

It's still possible to customize the stock rom.
I have made some modifications to it and flashed no issues.
This means it can at least be debloated.

You're going to need to use Linux, recommend Ubuntu.

I've just bought a SN 280 Tab A6 and I've been looking to root it to be able to take off some of the apps I don't use.
Is there any root, twrp or cusmom ROM for this device?
Thanks

Did you even read this thread? :banghead:

It's still possible to customize the stock rom.
I have made some modifications to it and flashed no issues.
This means it can at least be debloated.

Hello ashyx
I have the sm-T285m. Yes, I could not root it using the usual programs out there. Any way to inject root into the system image and then reflash it through odin? (as you mentioned you have managed to debloat it-maybe a dumb question as am sure you already looked into it) I recall trying to do such a thing on Huawei Mediapad x2 when there was no root but ran into issues after I accidentally overwrote my entire windows o/s and disk with linux and then gave up (had to extract files from image, add the su then recompile something like that?...from memory over a year back and was only my first and only foray into linux) The odin tar files are separate ones for modem, system, bootloader etc.
Thanks

I already tried prerooting the system image.
It wont boot because the boot.img needs to be patched and you can't patch the boot.img on a bootloader locked device.
I even asked Chainfire if there was any other way and he said no.

Thanks Ashyx...you mentioned you managed to debloat it. I tried ext4unpacker (maybe archaic now though recall it worked on 5.0.2) to separate the system.img into components but could not. I am interested in editing system image
(A) change dpi (increase the lcd density to 380 or so to get things bigger),
(B) change system font (put in a preferred ttf font),
(C) remove many unneeded (for me) google apps from the system folder, and
(D) enable mobile data auto on off for mms via the features.xml or others.xml. Do you think these could be done (you already mentioned the debloat).
typically i managed to get all of the above done if rooted.
Any advice appreciated on how to do this unpacking and repacking.
Thanks
does this help? opensouce kernel?
(again maybe preaching to the choir but thought I'd ask-not knowledgeable here but posting if it helps in getting to a semi-rooted type state somehow)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=sm-t285
btw i 'managed' to get oem unlock to show as checked permanently...does that mean the bootloader is unlocked now? (cross flashed through odin the 285 on my 285m the system CP file...and reverted back to 285m-no difference though in network as modem was still 285m as was partition and BL-reflashed the BL as well separately for 285m-after all this shows oem unlock checked-when i got the device new it was unchecked)
edit...from what it appears, it means it CAN be unlocked, yes? but not actually unlocked?

It wont make any difference. Enabling OEM unlock doesn't unlock the bootloader.
You still wont be able to flash unsigned boot or recovery images.
It will only allow you to flash an unsigned system image.
I use Ubuntu to mount and edit Ext4 images.
You can use the windows or Linux version of simg2img to convert the sparse image to raw then mount in Linux
Tbh Samsung need to provide an unlock for this device like they do for the Chinese devices as there is no reason why this device should have a locked bootloader.

Root Issue -- won't reboot into recovery mode

Hi --
Old Galaxy Tab Pro 10.1 running kitkat. I am using CF Auto Root to root it via Odin and I get the "pass" in Odin but then it just reboots into the existing OS and Supersu is not on the device. The instructions I have been following say that you should try again but switching off the "auto reboot" in odin. I did that, but it just remains in download mode. The instructions said to take out the battery...which, not really an option for the tablet.
I believe I followed all other instructions: I have the correct CF Auto Root file for my build; I have the drivers from Samsung ...
Any advice is appreciated.

So you want to keep that?
If not why don't you flash TWRP and Lineage?

Hi, and thanks for the reply. Big picture is that I'd like to use the tablet but kitkat obviously is now not compatible with most apps. So really just any reliable way to root so that I can make use of up-to-date/current apps. I can research TWRP and Lineage -- I'm guessing there's a how-to on here somewhere.
Tablet version: SM-t520.

And , obviously, terminology may be/probably is "off" here (newbie and all) ... but I believe there's a step before being able to flash TWRP and Lineage - whether that's "rooting" or "unlocking" or whatever. I'm basically still "stock" at this point.

I see.
Imo it's necessary 1st of all to make sure it's on latest stock to have latest bootloader.
Flashing TWRP with Odin is extremly easy.
Here is a post/thread although written for S4 valid for most others as well.
Written a how-to myself as well but the english part is not as up-to-date as the german is.

No unlocking necessary with that old device.
Rooting means having SU or Magisk but flashing works without as well.

Great, will give this a shot later today. Appreciate the help!

Well, didn't get very far. My understanding is that you have to unlock the OEM bootloader under developer options...which, ... well, I don't have that option listed once I've accessed the developer options. Tried a bunch of options -- factory reset, changed date/time to long ago .... used Smart Switch to check for updates (which one post said would prompt it to appear. Any options for getting this modded without the OEM bootloader unlock option? One post somewhere said that having the USB debugging option checked would work, but .... questionable.

Just use Odin to flash latest TWRP,
Reboot to that TWRP,
Wipe everything plus "Format Data"
Flash suiting ROM and test if it works
reboot to TWRP and flash Gapps fitting this ROM version (I prefer Bitgapps ARM)
Be happy

@tojotojo remember that Odin can only flash .tar and .tar.md5 files
TWRP.....img are to flash later in an old TWRP to get a newer one.

you need check off auto-reboot. it still in dload-mode, then press power to reboot and just as you see it starts boot press recovery-mode key combination to enter recovery. if you are slow, tab will load default system without ur root and recovery. i hope this help you.
