I received an SGH-T989 that wouldn't boot. It had TWRP on it, so I was able to flash latest stable CWM. Upon reboot, it apparently became hard-bricked.

Currently, I'm unable to enter download or recovery modes. USB Jig does not work. There is no output on the screen, even when charging the battery. When connected in Windows (32 or 64), I get a usb error message: "This device is disabled because the firmware of the device did not give it the required resources. (Code 29)"

My question: Is the motherboard dead, or could a jtag repair fix it?

What I've tried:
  • multiple micro usb cables
  • usb jig
  • odin
  • keis
  • heimdall

Thanks xda!

That would be great! I did see the S3 fix that loads a debrick.img from sdcard - would that work with hardbricked? Windows wouldn't load the usb drive for my phone, complaining that the firmware didn't give the "required resources". So if the firmware is borked, I'm not sure it would be able to load an external img.

I couldn't wait, though. Sent it out for jtag repair

Jtag should always do the job, unless there was physical damage done to the motherboard.

Thanks for the quick reply , i guess the next question i should ask , is it really worth the 100 bux for the j tag service or to put the money towards a newer phone ?,hmmm rhetorical i guess

The t989 has great specs, only downside is its PPI (really low) if you still love it, I would wait if you want to send it into JTAG repairs, we are on the verge of unbricking our t989 without JTAG! Looks like we need someone with a working t989D though

I have been studying the other 'unbrick' methods, its definatly mind expanding, the amount of knowledge absorbed can seriously make you forget time n space.

If there is anything I can do / contribute holler at me.

Now ill tell you something weird so I flashed a rom not meant for T989D plus I did it all without being rooted. (if it matters) since Since the flash the phone doesn't boot into recovery or show a bootanimation, just darkness.Yet it felt operational in hand.

Once I plugged it back into the PC all I got was a constant notification of drivers that cannot be identified Also it keeps connecting and disconnecting the device.

None of this is weird until I installed OMAP flash and the T.I. drivers for which was used to fix my friends nexus. After he left I plugged my s2 to the PC still nothing. I looked away for a brief moment . Then i noticed MobileGo for Android popped on screen. Visually showing my s2 as an Alcatel rom.

just bizzare.....

The unbrick method on the S2 is a little different, but in General, at http://forum.xda-developers.com/show....php?t=2646310 after a little work, I resurrected a QHSUSB_DLOAD 9025 T989D to the point of ODIN and fully working Android OS working, just missing recovery.. Soon to follow in a day or so.
