xPureEvilx

I rooted my phone yesterday, but had my MSL for over a week and flashed my first PRL about 3 days ago.... So I know it works. =P

good things to know, we dont have alot of signal issues here. but its nice to know how to do the stuff, ok sooo i gotta ask which PRL did you stick with.

amedasu

Nice work. Couldn't be simpler. You may want to add a step on how to back up the original before someone asks.

xPureEvilx

01120 -> The one in the Pics lol.

It seems to be a little better, but Iam still looking for one that will work good here.

jmc0228

I don't get port COM5 I get Samsung Android USB Diagnostic Serial Port (WDM) on COM20 and they say COM20 in just for registered version only so I can't connect. Why am I getting COM20 and not COM5 like xPureEvilx?

xPureEvilx

I would try using a diffrent USB Port, But other then that Iam not sure.... Anyone else have an idea.



Sorry,
PureEvil

CherokeeBlood

This is an excellent post. Thanks. Now to figure out what one works best for me.
One question currently. Does changing the PRL effect my service. will ST notice anything?

xPureEvilx

A PRL will just change the priority in which you phone connects to cell towers. Can be better or worse it just depends on where you are and which PRL you use.

Straight Talk shouldnt be able to detect that, but I just wouldnt call Tech Support and give them a reason to look at your info.

[Disclaimer: They could cancel your service for stuff like this, but its very unlikely this would ever happen. But proceed at your own risk.... Tip: If they ever do ask, Playing dumb can go a long way.]

CherokeeBlood

Yeah, I've been with ST for awhile, had the Razr, which got excellent signal out here in the boonies, would still have if it weren't for a 3" downpour while camping. It was on the Verizon network, So I went ahead and got the Precedent, I have good signal everywhere except out her at the house. What do you think the chances are that I could flash a verizon PRL to the phone. From the research I've done so far, it seems that the phone has the same bandwidth. From whatr I gather, it's in the 800/1900.

PoorBoy52760

since i have been checking PRL files most of them have the verizon, as well as Sprint, and Alltel, Cricket, and other networks already in them the problem is that you have to be within like 5 miles of a tower to get a decent signal. you could try a verizon prl but i am not sure that you would have service afterwards and would have to revert back to a sprint prl file, if you look in the PRLs post i posted some of the newer prls for sprint including a hybrid its 61677 you could try these and see if any of them help..

CherokeeBlood

Tried the 61677, Notta on my end. When I find one that gets me connected out here. It will definitely be the one for everyone. I'm so far out in the woods. I have a tower in "Town" quotations are dependent on what everyone defines a town. It isn't a sprint tower. I opensignals, and it points out toward the nearest city. I run it about mile from thetower, My guess since Verizon is a5 bar connection. it is a tower verizon has vested interest in. I just changed over to the new PRL listed in the PRL files thread, we'll see.

I'll post later.

CherokeeBlood

update post in PRL thread

GreggWh

I have followerd these instructions, and flashed my 1st prl, I tried to do another, and cd-ma says "failed phone does not answer". Any advice would be greatly appreciated.

xPureEvilx

It does that to me if I use an invalid PRL file. Did you get the PRL file from this thread or somewhere else on the web?

GreggWh

I got the PRL's from this thread, from some further reading, it's indicating that my phone is not turning on in DM. I am going to try removing battery, rebooting, then dbl checking USB debugging. I'll see if that helps. Thanks

PoorBoy52760

it takes more than usb debugging turned on to flash prls, follow each step of this Guide to the letter and it will work everytime.

twistdshade

Noob question here (first post, hi)...

What advantage does this method offer versus the "Update PRL" feature in [settings- about phone- system updates].

It seems like an awful lot of extra work to do something that can be done with just a few taps on your phone.

whompus60

The theory is you can get use of towers not really designated for straight talk.

Rebecca928

I tried to download cdma-workshop via the link you provided, i downloaded demo and the gethardware id files and when i try to open them it wont, what do i need to open them with?

Ruronin

I followed the guide to the letter and it still only shows the soft modem, it doesn't allow me to see Samsung Android USB Diagnostic Serial Port at all

any help would be appreciated, i'm eager to give this a shot

xPureEvilx

Did you download and install the Samsung USB drivers?
Are you using a Samsung USB cable(yes this makes a difference)?
Is your phone in Debug mode?
Did you connect the USB cable to your computer?
Did you try a different USB port on your computer?
Do you have any issues when connecting your phone as a mass storage device?


This is the most common problem when people cant connect:
Goto your Phones DialPad and dial ##8778# -> enter your MSL -> Select USB

You have to do this step every time, and if USB is already selected then unselect it and reselect it. (You have to do this everytime)

Ruronin

yes, i have done all those things
re did all of it 3 times, still no luck with getting the proper com to pop up

senser934

ruronin:
did you try clicking the actual port button that was my problem

LJS

I believe that the issue is actually that some modded ROMS will not supply the Diagnostic Driver on the USB. I rooted and installed GB2.0, and the phone no longer provides the Diagnostic Serial Port. I confirmed this by using the same methodology with a stock phone. Apparently the GB ROM does not provide the full functionality. Only the Samsung Android USB Modem shows up.

I also checked the drivers, and USB connection history, and that also confirms that my Custom ROM phone simply no longer provides the Diagnostic Serial Port on the USB.

Hope this helps provide some direction. Open to suggestions.

unknownpro

I use the gb arearom 2.1 and I am having same issue of only seeing the usb modem. It worked fine before arearom to flash prls.

GreggWh

I have spent the last 2 days trying to figure out why mine doesn't find the USB DM port. I just recently flashed the GB 2.0, and I can't flash any new PRL's. Now I can stop trying to resolve it.
Thanks

xPureEvilx

I love how the trolls made it so this post only has 2 stars, I am seriously considering removing all my posts from Android Forums. I have never seen a forum with this many children and trolls. Seems like only a few people here really appreciate the help and services we provide completely for free. Hadley seems worth the effort to even try on AF.

xPureEvilx

Ok this has been updated for AreaRom 2.x users

sweetb2006

Are these also the steps needed to be taken before doing "anything" via cdma workshop?

fileac

I can't find a working version of CDMA Workshop anywhere. Can someone email this to me?

rosser725

Can I use any PRLs or just the provided ones? I found a site that has some for Cricket, Boost, MetroPCS, etc.

B33p3rz

has anyone seen a straight talk (verizon) prl...the number is 59280?

Ibgooncrazy

This is just what I've been looking for!!
I have a Samsung Straight Talk (Verizon) that I just replaced with a (Sprint) Precedent.
I do not get a signal any where in my area on the new phone, and ST says that they cannot "flash" my phone, therefore I have to purchase another one.

I will def. use the PRL from previous phone and try my hand at "FLASHING"....Ah, ha, ha, ha..Ah, ha, ha, ha.....(feelin a lil wicked now)

THANKS for all the good info....you are,... simply put,... way to informed!
(Im Im way to glad that you are!)

palmtree5

It really depends on your computer. You can change the COM port in Device Manager to whatever you want as long as it isn't in use

You may want to try the program listed in the link below. This is what I use to change prls on my prevail and it may help you. Just follow the instructions for your phone. [Tutorial] Easy PRL change without using CDMA WS

Iambatmen

When i first tried this it worked flawlessly, but then i realized i didn't have a PRL. So I used the forum to get one. Then my computer died so i had to get it on a charger. After i had it plugged it in i retried and now it wont connect. It keeps saying " Failed...Device Does Not Anwser"
HELP!!!

Sldrluv

Well what are the sights

Rukbat

Any for Sprint. (PRLs are network-specific.) Whether the one you choose will work, or work better than the one you have now, is something no one can tell you in advance. It depends on the PRL and your location.

karizma420

when i click read on CDMA workshop it says the device is not responding. i beleive its because im not really in DM like i thought. i had to use Script manager but like i said, it doesnt seem to work. and i cant dial the number to turn it on because it says the code or number is incorrect. so is there any other way to turn diagnostic mode on? im also running CM7 if that is important. im very new to roms and flashing prls.
