Free and permanent t989 unlock

Warning: I am not responsible for any damage that happens to your phones. This is intended for educational purposes only. It is your responsibility to comply with local laws and follow them.

I read this post - http://xdaforums.com/showpost.php?p=34661189

and went searching for the same in T-989 and I found it!!!! Different area and slightly different procedure.

I haven't tried other ROM/Radios combos so I guess this was an unpatched bug for UVLE1 ROM/radio version combination only. If you do get it working different ROM/radio combos please PM me and I will modify the original post to reflect it with appropriate credits.

Clarification: This unlock procedure is permanent. I.E. if you flash another radio or another ROM the phone will remain unlocked. But for this procedure to work you need UVLE1 ROM/radio (some users have posted that you only need UVLE1 radio but for the sake of keeping in simple and accurate, I am going to stick to recommending UVLE1 ROM/Radio)

So enough of the rant - here is goes. Follow this to the dot and you will have an unlocked T989.

Prerequisites - T989 with UVLE1 Radio. If you don't know what it is please search the forum how to flash it and come back to follow procedure. You can follow this link for further reading for all other info - http://xdaforums.com/showthread.php?t=1324517 - (Thank You allgamer)

Hi All,

I'm a newbie and I have silly questions.
1) How do I boot into recovery mode? and how do I choose to flash a radio? Do I need to install a specific recovery software? I would really appreciate if somoeone will able to post a detailed "unlocking for dummies" guide, starting from an unrooted phone. A medal of honor will be given if the guide will start from a stock, unrooted phone.
2) I understand the latest version of the radio is UVLI. Should I use it or use the one that comes with my phone? (I would like as few problems as possible)?

Thanks!

No question is silly! I was completely a newbie 2 days ago, it took me 2 nights to figure it out, so for newbies that have some technical background, here we go!

*** NOTE that you only need to do the following if you have a radio other than UVLE1 AND you have tried the steps provided by OP and it won't work ***
*** All the file mentioned below should be easily found here ***

UVLE1 radio can be found here
http://goo.im/devs/Void_Dweller/SGH-T989_UVLE1_radio.zip

(You know I have to say this, I am not responsible for any consequence this might cause):

1. Download and unzip T-Mobile_t989_GSII_ADB_Drivers.zip, then run the installer from your PC, this driver is needed for your phone to communicate with your PC, hook up your phone to the PC and the drivers should be installed automatically, unplug your phone.
2. Download and unzip Odin3-v1.85.zip to your PC, this program is used to install the ClockWorkMod recovery mode, as you may think, you need to download ClockWorkMod too: download recovery-clockwork-5.0.2.7-hercules.tar and DON'T unzip.
Now turn off your phone, you need to boot it to "Download Mode": hold down Volume - and Home button, press the Power button for a couple of seconds until the phone vibrates, then let go the Power button while still holding the Volume - and Home, a few seconds later, the screen will prompt you to press Volumn + to enter the Download Mode, now you are in Download Mode
3. Hook up your phone to the PC, run Odin3 v1.85.exe, you will see the phone has been connected as "COM#", now we are going to install the ClockWorkMod, check "PDA", select the file recovery-clockwork-5.0.2.7-hercules.tar, and hit Start, after it's completed, unplug your phone, restart your phone and make sure it's working properly
4. Now we have the new recovery mode, why do we need it? Because we need it to install the new radio UVLE1. What is a radio? it's just some programs in your phone to provide the network, wifi, gps, etc functionalities.
Your need a microSD card to do the next step. Download SGH-T989_UVLE1_radio.zip and save the file to your microSD card. Open the cover of your phone, insert the microSD card, if you haven't put in the SIM card yet, put in the SIM card too.
Now we need to go into the "Recovery Mode", turn off your phone, hold BOTH Volume + and Volume - down, then press Power button for a couple of seconds until the phone vibrates, let go the Power button while still holding the Volume + and Volume -, a few seconds later you are in Recovery Mode. You should see some options with a hat icon on the screen, if you see a 3D Andriod logo lying down with it's stomach opened, you need to go back to STEP 2 -- the new recovery mode has not been installed. Please note that in the recovery mode, you have the options to backup your system, do it if you think necessary. Now select install zip from sdcard, select SGH-T989_UVLE1_radio.zip, use the power button to confirm, after the new radio has been installed, restart your phone and follow the steps provided by the OP!

Hope you enjoy your new phone, I've done this and successfully unlock my T-989D to work with WIND!!

I take the question... You just have to download this zip: http://goo.im/devs/Void_Dweller/SGH-T989_UVLE1_radio.zip

Once you downloaded it...

1. Put the zip in the SD Card
2. Reboot into Recovery
3. Choose the Zip and install it
4. then reboot

After you install this you should be back to bone stock. The md5 flashes the uvle1 radio, stock kernel, stock ROM, and stock recovery. DO NOT FLASH A CUSTOM RECOVERY AND ROOT before unlocking. After you unlock, do whatever you want, but in order to unlock everything has to be bone stock. Flash the md5 with Odin, which also flashes the radio, then unlock following the steps in the original post, you can can root, and flash any ROM, recovery, radio etc.
