[Q] Bricked Qualcomm's secondary bootloader, what to do?

Hello everybody,
I got my hands on this phone and I tampered too much with Qualcomm's FAT partition with the secondary bootloader, hardbricking the phone itself.
Trying to turn the phone on, shows the Samsung logo for some seconds then shuts down and disconnects, Download Mode is unaccessible but with VolUP+Home+Power the phone just stays connected (with the screen being black), but ignores any attempt to flash, Odin staying stuck on "SetupConnection...".
What I've tried already:
- Flashing with Heimdall -- phone isn't even recognized
- Removing the battery "trick" etc, etc, etc
- Changing .tar.md5 package
- Forcing a repartition with the .pit
Any clue might be useful, thanks in advance to anyone replying.

You shouldnt had to play with the bootloader neither the SBL
Im sorry to tell you that if your phone doesnt acces neither recovery and download mode it is hard bricked
that is why odin doesnt recognize the device
however, USB JIG is the best solution (the other one is changing the motherboard)
You can follow this instructions http://forum.xda-developers.com/galaxy-s2/help/guide-how-to-make-usb-jig-reset-binary-t1604707 to build one
using this SHOULD work but its even possible your bootloader is so messed up that will not open
You told me there about download mode, what about recovery mode? althought it should not work maybe God gives you a second chance

Actually ODIN recognizes the phone, but hangs on "SetupConnection...", sure the simplest solution might be the jig if there's a secondary bootloader in situ.
Obviously the recovery mode is dead, but still, I saw that it bypasses Samsung's logo and just reboots.
Since it's Qualcomm, probably the microSD emergency procedure used on the S3s might be a fair try.
If someone has still a working phone, can please do a dd image of the first 100 MB of the EMMC so I can see if this option is viable?
Might be a nice solution for hard bricked Qualcomm-based Samsung phones to unbrick those.

First, for the SetupConnection try changing the ports but first BE SURE Kies is closed or end the task as Kies closes your connections using third-party programs
then reinstall samsung usb drivers or even adb drivers are good.
if you will find anyway to execute the command adb reboot-bootloader you could probably save the phone
2. I just read about the microSD procedure, it looks like a pretty clever idea
I wonder how do you know how many MB's you need
so i have done here a 70MB IMG, and with 100 didnt worked so I did a 99 MB one
Remember you need Class10 16 GB Card
If somehow this solved your problem, i will do a post in our General Section
Good Luck, i'll stay tuned.
EDIT: I just noticed the files have 169 MB so I can't post them here, tell me your email and i send you, my email is [email protected]

I don't have Kies installed, since I never kept any Samsung phone with the stock TouchWiz ROM, but only the USB Drivers package for ODIN and so on.
I sent you a PM with my e-mail address, but you could upload the img to MEGA or whatever file locker service...
In the case this get sorted, I'll upload the IMG over my server and drop the link, so you don't need to worry about the link expiring or whatever

Tried to burn the SD card, it seems that the 7227A doesn't support boot-from-SD.
Anyways, I ordered off eBay for some change a jig dongle, as soon as I get that I'll try that way, but I think that it won't work since most of the hardware components (except for the NAND) are not made by Samsung.
I'll let you know how it proceeds

Galaxy s6 stuck at boot? Unable to fix

Hi xda members, im new in here and i was hoping for a bit of help
My phone is galaxy s6 SM-920T
I was reading on the net when the phone powered off and started restarting and restating again and stuck at book logo "powered by samsung".
I am not able to go into recovery mode but i can open the os download mode.
Tried many times with odin and no luck
I think due to the phone being full encrypted by me nothing can be done, is there any posibility? Thanks

The same here. I cant get into recovery. I had Terminator Rom installed. I can get into download mode but odin doesnt detect it. I eventoght the usb door was damadged so paid 60$ do replace it at samsung. But odin still doesnt not recognize it. Odin does recognize my Samsung Tablet 4.

Have you made sure you have the latest Samsung drivers installed on your computer?( http://developer.samsung.com/technical-doc/view.do?v=T000000117) And after that, try to see if Odin recognize it download mode, after you have confirmed you wanna flash new Rom ( volum up)

I've had cases where you had to put the phone into download mode THEN open Odin for it to be seen. Maybe try that.
With it in download mode and plugged up open devices and printers and scroll to bottom and see if it shows up. Would be called gadget_serial. Some computers take a while to load the drivers for it as well. You may want to click little popup menu on bottom right of desktop by the time and date and see if it shows it is loading drivers for it. It will not show up until the gadget serial drivers are installed.

Thanks for the help. Nothing worked. It doesnt not recognizes the S6 only my Galaxy Tab 4. Could it be that the usb door wasnt repaired proprely ? Windows doesnt even detect the phone no gadget_serial. Nothing.

Make sure that You're using USB 2.0 not 3.0. My Note 4 worked through usb3.0 without any problem. And S6 doesn't. And if Odin reflash won't fix it. Get pit file and flash it with it.

So it doesn't recognize it all all? Doesn't give you unable to read device error or anything?

First thing to try would be flashing stock firmware with Odin.
https://www.dropbox.com/s/rb8iduv2o9i1ece/G920TUVS3DOJC_G920TTMB3DOJC_TMB.zip?dl=0
I recommend Odin 3.10.6
https://www.dropbox.com/s/1dlmxtc0ic7u7ew/Odin3_v3.10.6.zip?dl=0
Report back.

already done, with same results stuck at boot loop, tried to add a custom recovery which got denied by knox

Sounds like DRK may be damaged.
Take the stock OKC firmware and open the archive with 7-zip or winrar and extract the system.img and boot.img.
Download and unzip this:
https://www.dropbox.com/s/bsreazoonsw4gwv/tar-Tool_Odin3-v3.07_by_mkh.mourad.zip?dl=0
Copy/paste the system.img and boot.img into the software directory and run the batch file. It will spit out a system.tar.md5 and boot.tar.md5
Flash the system.tar.md5 with Odin as AP then flash the boot.tar.md5 as AP.
Report back

thank you gonna have to try tomorrow due to bad USB cables, will let you know thank you so much for your help

If all else fails, just boot your phone into download phone and install Samsung Kies and restore it using that.
You will need the model & serial number of your phone. It will restore the latest stock firmware on your phone for you..

how can I check the serial number WITHOUT my box and booting into the phone? my phone's bricked as hell

You cant, I suggest using a friend or family member's serial number that has the same model phone.. the serial number is a way of identifying the correct carrier specific rom.

Bricked S7 Edge

Hi All, first post here and I'm 90% sure this is the wrong thread but I can't post in the ROMs, KERNAL, RECOVERIES thread....
Let me get to the point, I have a Galaxy S7 Edge (SM-G935W8) that won't show anything on the screen at all. No backlight or anything. I've tried using Odin to reflash the original ROM but keep failing on the re-partition. (Holding vol down, power and home will enter download mode and a solid blue light shows. The PC does recognize the phone but ADB doesn't since USB debugging wasn't enabled.)
Any ideas or is the NAND completely shot?
Thanks.

Tried repair via Smart Switch?

It tries to connect then says unsupported device. Emergency reset asks for a key...

Completely wrong forum too lol
https://forum.xda-developers.com/s7-edge
ADB being enabled has nothing to do with Download mode, as Download mode is independent to the firmware
Make sure you're using ODIN 3.12.3 or newer, and that the COM port on ODIN is showing as connected
It's not 100% that the phone is entering DL mode though if you have no display

Key is your device serial number iirc
Back of phone

I can get it to connect to ODIN.
COM port shows along with "Added!" but it always fails at the repartition step. (I'm adding all 4 of the files at once I believe that is correct?)

Yep that's correct, are you trying to flash the same CSC or different?
Different CSC you might need to check the "Re-partition" option in ODIN settings as they can be different sizes
But no display in Download mode = Not a firmware problem, almost certainly a hardware problem

Alright, looks like I'm buying a parts phone and doing some surgery tonight. Thanks for the help!

Good luck

Sprint Samsung S8+ qualcomm mode

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

Doesnt work, the device is completely dead.. so neither bootloader, neither download mode, neither fastboot will work..
I have been researching about EDL mode (emergency download mode) and its the only thing i managed to do, by shorting the testing points of the device.
But i dont know what tool should i use while on EDL mode, odin doesnt read my device on edl mode

I also don't know about it, YET
