**cac9478** · #1 (**permalink**) 05-27-2006, 04:15 PM

I am going to tell you how to manually update your phones PRL (Preferred Roaming Location) so you can avoid going through CS.

1. Have your MSL code handy*
2. Download the PRL file
3. Unzip onto your phone
4. In phone, type ##775#, enter MSL code
5. Tap Update PRL, Then click edit
6. Select Browse, then click the file
7. Press Ok, Ok, Yes
8. Press Ok to reset the device

* If you need your MSL Code do this.
Call Sprint. Go to Activations line and get ahold of a human being. Tell them you are programming your phone and need your MSL code. They should give it to you no questions asked

There you are done. You have just manually updated your phone to the latest Sprint PRL without having to listen to CSR telling you your phone is already updated.

I think sprint's csr are just lazy. I call up there and they tell me my prl is updated and it wasnt but there was no getting through to these people. So i found the file and upgraded it myself.

it's funny, this is the ONLY way I can update my PRL and if it wasn't for this method, I'd still be using my 650!

Seriously, I was stuck on 20216 forever w/o any OTA success. I finally took it to a Sprint store and they couldn't even do it there.

Like hell was I going to go through Sprint support...I could school those guys on this phone.

having said that, unfortunatlly 20222 didn't increase my reception at work...damn.

Still it's worth it and I'll probably get better evdo somewhere around NY/NYC

Remember.. this is a Preferred ROAMING List. It will not affect your native Sprint coverage whatsoever. Only your roaming.

Not quite Rennyn...

From Chris Price (pcsintel) and I've seen this elsewhere, though it IS true that on a 1x device it only affects roaming, on evdo it is slightly more complicated:

Quote:

Keeping the PRL up-to-date is not critical. However, savvy users chose to update their PRLs because it provides for faster roaming signal acquisition, improved international roaming, and, on EV-DO devices, better acquisition of EV-DO data services.

Quote:

On EV-DO devices it can add HDR channels, which can improve EV-DO data coverage. If Sprint is or will be deploying additional HDR channels not in the PRL in unlaunched markets is unknown at this time, so, it is best to keep the PRL up-to-date on EV devices.--C. Price

Quote:

Unlike PRLs in older devices, EV-DO PRL files may make modifications to the available HDR channels, improving EV-DO signal acqusition.

I'm not saying it will gurantee a difference but you never know...
