Hello everyone! I'm new to the forums as a member, but used this for info since a few years back. Ok, so i've spent the past week trying to unbrick a samsung galaxy s2x (t989d on telus or koodo) and it seems alot of people are having trouble with this model. I've brought back another one identical to this one before, but it was only softbricked, so i could still enter download mode and use odin and just searched my butt off to find original roms and all and wound up bringing it back to life.
This one though... It's hard bricked with the dreaded QHSUSB_DLOAD mode. Found drivers for it to use it in windows, found QPST 2.7 build 422 and tried that to no avail since QPST always tells me the HEX files have a scrambling method which cannot be determined (even with it's own hex files that come with it, and tried on 2 different computers, one x86, one x64) so still stuck there. Tried ADB in windows but it never wanted to work in any way, also tried ADB with ubuntu linux but the devices list always ends up empty no matter how hard i try and what i change, even with other phones that are not bricked it won't list them at all... Also tried to use the SD card method and push an image on it to try and boot off the external SD using original rom from odin i have found, but have no idea exactly which image i need to push into the SD or if it need modification in any way to be able to boot like that, or if even the t989d does in fact truly support external SD card booting.
Before anyone says:" Ya you need to JTAG that, it's the only method..." First, no one around here has anything to jtag with and i don't want to cross the border to get it done, second this is the kind of job i need to get done without spending any money if at all possible cause phone is not mine and client on a restricted budget. Now i know this CAN be done as alot of people here and there were able to fix their phone that were on the same qualcomm series chipsets. I just need some help to do this on this phone, and any SERIOUS help would be apreciated.
I have access to original rom file for the particular MC4 version i have in hand, i have original rom file for another version of the 989d which i got to unbrick the first t989d a friend sent me, i have a NVbackup qcn file pulled out of my firends working t989d, and i also have a full backup made with TWRP on my friend's working phone. Wanted to pull out a better backup using darkspr1te's Brixfix-2-1 tool but like i said, in windows ADB wont work in any way even with python installed and all that, drivers also installed, but ADB isn't a recognised command. And in Ubuntu, no way to list any phone at all, even if i installed all the ADB files, JDK, did the whole rules file, changed attributes to the rules file, did the .ini file, and killed and restarded hdev and server... So i'm kind of at witts end right now, plus i've been sick and had a major headache for the past 2 days, and spent so far around 38 hours on this phone plus my normal job this week... So ANY help would be GREATLY apreciated, and i will gladly use this experience to help out the community and help put out a tool or whatever to unbrick all these damned t989d
Just le me know if you need any more info or files to help out and i will gladly do all i can to comply
Thank you in advance to this great community
Nobody?? not even a troll ?? pretty sure that not even a mouse is stirring
Update: I have finally been able to start to get somewhere with this. I was able to extract most of the MBN files needed for QPST from the stock rom, and created my own partition.mbn out of a PIT file i had from a previous t989d. And now i get the phone to accept download and don't get errors for those files, but it stays stuck when sending reset packets. So my guess is that either the partition.mbn file isn't good, or the mprg8660.hex file i used to substitute and test isn't 100% compatible with the MSM8260 chipset. I tried all i could but never was able to find the real mprg8260.hex file anywhere. So if anyone has mprg8260.hex and/or a working partition.mbn for the t989d, i would be grateful to get those so i can continue troubleshooting this and get it working. If you want any of the MBN files and everything i have so far, just send a PM or reply to this thread and i will gladly upload for you.
Don't use the 8660 hex, it might make it go out of DLOAD or SD mode and you'll get a HS-USB 9005 state instead of a HS-USB 9008 or a HS-USB 9006 state, and then you'll need to manually flash it while it reboots every 5 secs in factory recovery mode. Not fun stuff. Also, if you're playing in QPST, make sure you using 2.7.411 or later. And be careful. there is a 2.7.422 that is actually an old version with a Trojan floating around.. Also, be warned, If you don't know what your doing in QPST, you can make things a lot worse.

So far i had no problems using 8660hex, only stays on 9008 download mode so far, even after it's supposed to pop back to diag mode. And i AM using 2.7.422 but it doesn't seem to have a trojan or anything or else my anti-virus would've told me, but still kinda looks like an old version since most of the devices supported are the old ones and has nothing newer than 7XXX series on protocol modes in the settings menu. But like i said, so far i got it to respond with the 8660 and accept the mbn files, but still no change yet, still wont reset/reboot, still wont turn on or anything, just stays in download mode seen as a 9008. So i'll check to find 2.7.411 to try it out and see if does anything else. Even if it would reboot every 5 secs in factory recovery mode it would still be a step further than i am now right now it does nothing and stays in download mode. But thanx alot for the info!!

hi,
were you able to resolve this ? I have the Skyrocket (I727R) and i was wondering if you could share the files and possibly how you fixed this problem,
any help would be appreciated.
thanks
So, messing around with kernels and stuff, I wound up with a bricked device (wouldn't turn on, no response to anything, etc [I did eventually manage to get it functional again through a combination of button mashing and praying])
However, when plugging it into my computer, it showed up as "Qualcomm HS-USB QDLoader" which seemed interesting.
Searching the internet, I found several things. The QPST (Qualcomm Product Support Tool) Software suite, as well as other less useful links about the LGFlash tool, etc.
The programs also makes reference to debug and other modes, but there isn't a lot of documentation on the internet.
What I want to know is, is there a way to put the device back into the QDLoader or other QPST related modes so as to either update the firmware again, or just make backups for future use?
If there is, this seems like it would be a great tool for undoing any damage to the phone that isn't hardware related (the documentation says this part resides on a read only chip[which it seems fastboot doesn't])
It looked like you borked your phone to the point where there was nothing recognizable as Android left on it. I don't know anything about this loader but based on my past experiences dealing with proprietary OEM tools (Samsung KIES), I hope I never find myself in a situation where I'd need to learn. :crying:
Turn off your phone. Press all the keys if nothing happens your phone bricked. If you end up qualcomm 9008 mode we cant do much, because we dont have a working flash programmer and a working bootloader which would be flashed to the phone with the flash programmer. You can do 2 things. Replace your motherboard, or find the emmc pins on the motherboard to get direct acces to the storage then with a modified sdcard reader you could have access to the storage content then you could restore the bootloader. This is pretty hard method almost impossible.
If you have qualcomm 9006 mode then you can restore the bootloader with any kind of linux, because in 9006 mode the phone acts like a external hdd.
May I ask how exactly you messed around with the kernels to get this? Did you flash an incompatible kernel or something?
It sounded like he resolved his issue and wanted to know if this hidden mode can be used.

to enter qload mode you have to turn on the phone then press everykey at the same time until the screen turns off
It works!

Thank you! This works!
It still only puts it in download mode, not the diagnostics or anything else. Although.. That may just be a project for when there's better documentation, or I don't actually need this phone for normal use...

To achive diagnostic mode you need a working flash progfammer and bootloader which can be loaded with flash programmer. We will never have these files unless someone at qualcomm build it for nexus 5 then share it here on xda.
With LG G2 if something goes wrong during ota update the phone starts in qualcomm 9006 diagnostic mode.
Well darn

Ah, darn. I suppose we can just hope though. Maybe someone with too much time will find a way to do it on their own. Oh well. Thank you!
I've never bricked my phones that bad man when I was a noob I installed safestrap on a device with an unlocked boot loader and tried to flash a ROM it didn't work out to well,man that was about two years ago

There were two placed where qualcomm documentatiosn could be found. One was a chinese forum where you have to be veteran or admin to get access to the files. This forum not exist anymore. The other is a chinese ebay like website where they are selling qualcomm documents for 3000 usd.
If you search for msm8974 boot flow or sahara protocol you will find file names for qualcomm pdf documents. Sadly just file names no download possibilty.
Hi my name is Miguel and im new to xda and i have a serious problem so i bought my phone and i was using it a mp3 and stuff since i live over seas i tried to region unlock it and in the process bam phone restarted and nothing but a black screen i plug in my phone to my charger nothing happens i plug it in to my pc something happens but not on the phone but on the pc it started downloading drivers i can tell you what the bubble said because i came to europe for vacation and im staying here for a while but a friend of mine said your phone lost his boot-up and it wont do anything unless you buy a medusabox and get all the files im buying the medusabox or whatever but where can i get the files from he told me you need 4 files with ones are they any ideas?
What were you doing to region unlock it?
If you hold down the bixby, power, and volume down buttons, can you get into download mode?
I too am in a similar situation. Not trying to highjack the thread at all however I believe it's what they call EDL (Emergency Download Mode). Mine is in Qdloader 9008 but cannot use QFIL to flash it so stuck with this brick for now. The files, I have some XMLs and supposedly the programer but they haven't worked for me at all.
Good luck, please advise if you ever fix it cause I have faith and hope its just a matter of time i can unbrick mine.

Im trying to use medusabox which is what people use to recognize qualcomm mode i just need the file to install the bootloader to get it into download mode any ideas if i can get them from another s8+
The file that ur looking for isn't apart of the stock firmware? BL,AP,CP,CSC, and PIT. I think the one ur looking for is BL for bootloader. You shouldn't need a box to recognize 9008, this is something ur phone should do automatically when u plug it in while hard bricked thought that all of the boxes were made to be able to flash ur device while in EDL mode?

This is very old but no all bricks dont leave in edl the devices also have groind points. All of us that tested the edl repair use qfil or the recovery script which i use on mine. You need a bit more than just the bootloader for repair. A whole barrage of sperate partitions as well as the programmer xml

I finally have managed to get my supra to go into edl mode. I got my phone to finally show up a q9008 device but no im stuck i dont know how to flash anything over i have never brought back from the dead a qualcom device. It seems a little harder than a mediatek device. My question is now how do i get the firmware to flash when there is no firehose script. Any input is greatly appreciated. I will be posting shortly a picture of where i shorted my board and it wasnt on the jtags more up and center on towards the camera.
Hello fellow members, i need some help to put my device into edl mode, i tried with a cable and adb, device just restarts and boots instead of going into edl mode, any help appreciated. Thank you

Do you have the fire hose programmer? You need a specific edl cable there isn't even diagrams of recent samsung phones for pin outs. What are you trying to do?

Hello, thanks for the reply, actually i was able to put it in diag mode and connect to qfil and backup qcn, i am trying to convert a demo into a working phone. I can edit qcn and flash back with no errors but it does not change the imei. Any suggestions? Thanks

You can't imei is cert file written specific to that device. Your not gonna get much help on here. With imei related stuff. Even if you do write a iemi the cert will fail and it will refuse signal.
