How to Flash a Blackberry cell phone

I am going to show you how to flash your Blackberry to any CDMA carrier. First you will need a few programs such as BlackBerry Desktop Manager or Sprint Mobile Broadband, UniCDMA, QPST (main flashing program), WINHEX - UniPST (Universal PST) & Rim DLL.

If you get there programs from the internet be very careful of any virus. I got everything here from www.yourcellular.net/need_help.htm along with a video tutorial.

1.) First download Blackberry Unipst
2.) Install QPST
3.) Install BlackBerry Desktop Manager or Sprint Mobile Broadband
4.) If Installing Sprint Mobile Broadband – Make sure BlackBerry is checked during
installation!
5.) Restart your computer, then go to your Device Manager, and check under Ports
(COM & LPT) there should be 2 serial Ports for RIM (e.g: COM3 and COM4), now
you need to remember the highest number COM port for your blackberry. Note:
If you have a Sprint phone the ports must be less than 4. If they are 4 and 5 you
will not be able to read your SPC (unlock code). Change the ports to consecutive numbers less
than 5. 1 and 2 or 3 and 4. Then reboot your computer so they will reset and
detect the phone.
6.) Turn off your wireless connection in the BlackBerry phone. Then connect it to
your PC via a USB cable and run Sprint Mobile Broadband or BlackBerry Desktop Manager
7.) Run QPST Configuration. Click on Ports tab and add new port (add your
blackberry port, the highest number port)
8.) Then click Start Clients - Service Programming - Select your phone, for phone
model select SURF6300-BB or a file that ends in BB for Blackberry.
9.) Enter your MSL code (SPC) when prompted ( your unlock code)
Obtain your MSL code from your service provider or read it with UniCDMA.
If you have a Verizon phone MSL (SPC) is 000000
If you have a Sprint phone or other service provider that is locked you must
use UniCdma to read your SPC.
Read this Memory section of phone with UniCDMA: 0x106C0000-106D0000
Use WinHex to Search for hex value: 00 07 00 02 04 00 00 00 00 00
SPC will be found like this: 3x 3x 3x 3x 3x 3x
Write down the number for each x and that is your SPC.
If you don’t find your SPC here then try these…….
Possible Memory Locations of SPC:
Using UniCDMA read MSL/SPC from the following:
Blackberry Pearl Address: 0x106c9e79 Length: 1703936
Blackberry 8703e Address: 0x10050000 Length: 1703936 (updated address)
Blackberry 8830 WE Address: 0x10057700 Length: 524288
Blackberry 8130 Address: 0x10129990 Length: 25000
Blackberry 8130 Address: 0x10630000, length : 1703936
BlackBerry 8130 Address: 0x1067ed90 Length: 1703936
Blackberry 8800 Address: 0x10630000 Length: 1703936
BlackBerry 8330 Address: 0x1067ED90 length: 0x00100000
BlackBerry 8330 Address: 0x1067ed90 Length: 1703936
To find SPC – first read memory with UniCDMA and then open with WinHex.
In WinHex select Specialist – Gather Text – Change to 6 and check NUMBERS only.
It will ask you for file size. 100MB should be plenty sufficient. This will show you 6
consecutive numbers. One of the 6 consecutive numbers will be your MSL (SPC).
10.) Download service provider prl from Corolada PRL Page then save it to your
computer. http://www.corolada.com/prl
11.) Back in qpst, click on the roam tab , under preferred roaming, load the prl
12.) Click on the settings tab, change service programming to 000000 (6 zeros)
13.) Click write to phone
14.) Phone should reboot.
16 ) Now disconnect the phone, and call 611 to make sure the phone connects to
customer service of new service provider.
If you try QPST and get NV locked error then you need to use Universal
PST.
