Still on Telus network with T959P on T-Mobile Firmware

Yep, still on the telus network. Maybe the Tmobile bin just doesn't show the 4G like the old Telus bin did because I am getting download speeds between 4 and 7Mbs.

In the end it was pretty easy (if I take away two days of seeing the phone go from bricked to partially booting). Here are the steps I followed, and I have repeated these to verify that they work as well. I still haven't found any issues with the phone except that it isn't recognized in Kies with the Tmobile software

Download the following files in the Tmobile section at Samfirmware.com:

T959VUVKH2_TMB.zip

T959VUVFK1.zip

This file can be found elsewhere. I had originally posted links but I am a new user so not allowed.

stock+Voodoo-T959VKH2.tar

Hawk_Sidekick_VibrantPlus_831.pit -- Can be found in the T959VUVFK1.zip file

Once you have downloaded the files above:

1) Extract the files with 7zip.

2) In the extracted files for T959VUVKH2. Find the CODE_T959VUVKF1_CL270364_REV00_user_low_noship.tar.mdf

3) Extract cache.rfs, factoryfs.rfs, modem.bin and zimage to a folder on your computer.

4) Now extract the T959VUVFK1.zip so that you can extract the file called CODE_T959VUVKF1_CL270364_REV00_user_low_noship.tar.md5 All we want out of this tar file is data.rfs which should be placed in the same folder as the files in step 3.

5) Now use Windows Tar to execute the following command line from the command line while you are in the same directory as the files you have extracted in steps 3 and 4 above:

tar -c cache.rfs data.rfs factoryfs.rfs modem.bin zimage > T959P Flash.tar

Flash the new file with ODIN

This should have created a new file called T959P Flash.tar. Simply flash this T959P Flash.tar file in Odin and your Telus phone will boot to TMobile 4G firmware. Make sure you put the T959P Flash.tar file in the PDA box in ODIN to flash it. Also make sure the Hawk_Sidekick_VibrantPlus_831.pit file is in the PIT box and the REPARTITION Checkbox is on.

Rooting your new TMobile firmware on the Telus T959P

Once this is done flash the stock+Voodoo-T959VKH2.tar file which will root, add voodoo and CWM the newly flashed device. Again just put the file in the PDA Box and flash it. FLASH this with NO PIT and REPARTITION NOT SELECTED.

Unlocking the Device

The last step is to use dd to backup the NVData, open it with a hex and use the search technique talked about on the forums to find the unlock code which works perfect as well.

Hopefully this helps someone else. There seem to be a lot of people like me who erronously flashed the regular Telus T959D firmware by accident or the Vibrant software which pretty much kills the T959P and bricks your device. This will get people back to a usable state and GPS, WIFI, 3G/4G and everything else seem to work....except the Kies connection which I sure will get figured out eventually. Maybe just a matter of exporting the device db entries out of a valid system so that kies will see it as a valid phone. Not quite there yet.

One last note. You apparently cannot completely brick the T959P in the sense that even when it is black the EEPROM will still boot to download mode. Just hold Power + the Volume UP Down button for 10 seconds, then let go of the power button and keep holding the volume up/down. If you have odin open you will eventually see it recognize the com port. May take a couple of tries but this made it easier for me to continue to flash it knowing that I could always flash another bin :-)
