How To: Use the Radio code from one OS build in another

[Sith_Apprentice]

For those users that experience frequent drops in data connection with a new build (particular a leaked beta build) this solution will help you use the new java components but keep your radio from your old, stable code.

1. Locate and Download the OS on your machine that caused your device to have good reception
2. Locate and Download the OS on your machine that you want to use, but has the data connectivity issues
3. Install both sets of software on your machine to the default location
4. Go to C:\Program Files\Common Files\Research in Motion\Shared\Loader Files and locate the two different OS installations.
5. Open the folder that contains the good radio code
6. Go to the GSM/UMTS/CDMA folder (your OS package will have one of those folder names) NOT the Java folder
7. Right click and Copy the only file located there.
8. Go back to the other OS installation directory and locate the same folder (GSM/UMTS/CDMA) and paste the copied file.
9. It should ask you to overwrite the current file, Click YES
10. If it does not ask you, simply delete the file that was already in the directory, and paste the new file in
11. Go to either Loader.exe under :\Program Files\Common Files\Research in Motion\Apploader or run Desktop Manager.
12. Update your OS as normal. You will notice that it might say "downgrade" in certain sections for the core OS. This is due to the radio code and should be ignored.
13. Enjoy your new hybrid OS.

Post any questions you have in this thread. I apologize if this is already here, but i searched and did not find anything. For those users who downgraded to .86 or .90 on the Storm because .99 had horrible Radio, This fix will work for you.








Edit:

Here are the list of Radios that Work at this time

Storm:
use the .90 Radio in the .99 OS
use the .90 Radio in the .100 OS

Bold:
.210 Radio in the .216 Code
.234 Radio in the .214 Code *causes reboots when browsing the web*
.234 Radio in the .216 Code

I havent looked at it actually. I am betting it is much more difficult than just switching out a file.

[cjcarbone]

Well i'm having isues even getting the OS on to my Storm. I keep getting app error 523. I tried all my USB ports, and wipe with JL_Cmder. Going to try to load up just .85, and see what happens.

What radio file did you use? I used .90 in the .99 build and it is rock solid.

Thank you Garz

OMG, what a helpful thread! I otherwise love .99, but I was starting to notice connectivity issues. I will try your method with the .90 radio code tonight.

I wonder if there is a way to get the bigger font code in to .99? THEN it would be perfect!
