Even easier just root your phone and grab MSL reader from the market. BOOM done.

 

Hey marke....still can not get this to work for me. I let logcat run for like 2hrs! I paused and filtered the words.."code" "msl" etc the log just remains blank OR it does not give me anything useful wtf am I doing wrong. I followed the directions

 

Moderator note 1/6/2013- changing your MSL is a VERY bad idea. EarlyMon

You must already have your phones msl code for this to work



Click the link below to download DFS. Its a fully working demo

that you can use as many times as you want plus its better then CDMA Workshop and totally free


Download CDMA Tool DFS software.


DIRECTIONS


Using your dialer dial *983*87274#
Choose Only Diag or if your only internet is tether (like me)
Choose All Functions



Open DFS and wait till the countdown completes

If you did not see which com port your phone installed to. Dont worry DFS knows.

Click on the port button




Now in the port list look for ZTE Handset Diagnostic Interface and double click it once there's a green circle next to it its activated.




Find the SPC box and type in your MSL code



Click the blue circle next to the word SPC to send the unlock code

If you entered it correctly this is what it will say on the log
window




Click on the programing tab to get to the SPC edit area



From here go down below SPC where it says STR and enter any six digit number you want your MSL to be in the white box.



The last thing to do is to click the red write button and your
finished changing your MSL just reboot your phone for changes to take effect
You can also click reset in DFS to reboot



TO CHECK IF IT WORKED




When phone reboots open DFS
Go to place where you input the MSL code and test your new code and see if you get the unlocked successful text in the log.

Or find a place that needs your MSL code in your phone and try it.

If it works open dialer again and enter *983*87274# and this time choose AT or usb will not work.



TIPS


Write down the original MSL code in case you need to change it back later.

I am not sure if your new MSL has to be 6 digits or not.

The MSL can only be numbers.

I would call the dial code leaving out the last # first
Then in your call list hold down on the number click edit
before call and just add the last # so you dont have to
remember the code or dial it.

If you enter the wrong MSL more then twice your phone will ether freeze or reboot.

I am not sure if you have to be rooted or not

I take no responsibility if you mess up your phone doing this if that is even possible.

Locate the nam tab




Now its time to backup your original prl in case one of the flashed prl's cause you to completely lose signal as to where you cant update prl from the phone its self.
Click the blue button labeled read under the prl section.
Once your prl shows up in between the box above the read/write buttons and the world enabled, click save and save it someplace safe.



Now that's out of the way its time to flash a prl to your handset.

Ether put all of your downloaded .prl's into the prl folder located in the DFS installation folder. (this allows them to show up under the local tab in the prl area). or just click the load button and navigate to where you downloaded them.



Once you have the prl that you want to flash loaded click the red write button to flash it to your phone.



The log box should look like this in the picture below.If everything went ok every thing in list will say ok.



The final step is to reboot your phone click the reset button at the top if you don't reset you will not have a signal at all




If everything was successful open dialer again and enter *983*87274# and this time choose AT or usb will not work.

(Once I download all the prl files Ill rar them and upload them all in one rar so you can put them on in the prl folder of DFS so you will have them all)

Here are my results so far for fountain/ludington which is in northern Michigan
i plan on testing every prl



Original boost prl signal 1 to 2 bars using speedtest app .50 to .73/mbs ping 386 ms


60686.prl no bars to 1 bar sometimes 2 the bars were white no 3g stayed on white 1x

60683.prl -- signal showed about 2 bars steady sometimes +1 bar 1.23 to 1.32 mb/s ping 310 m/s ? full bars when coming back from screen off but then drops back to 2 bars?


60711.prl ping 317-344 ms signal steady 2 bars some times steady 3 bars intill speed test app was launched then droped back to 2 speed .73 to 1.23mb/s mostly around 1.11 mb/s


60681.prl ping 324 to 345 ms speed .90 to 1.23 mb/s mostly 1.23 mb/s signal 1 to 2 bars mostly 2 bars steady



60680.prl ping 342 ms to 364 ms (mostly 3.63 ms) .56 to .72 mb/s ( 1.02 mb/s when 3g was full) signal switched between 2 and 3 bars constently 3g signal was only full on one test

60679.prl ping 344ms to 347 ms (mostly 347ms) speed first test.38 mb/s after that .92 to 1.27 mb/s signal sometimes full 3g signal 2 bars steady sometimes 3




60678.prl ping 460ms to 494ms 430ms speed .30 to .44mb/s signal 3g low steady 1 bar sometimes 2

 

will this work on the samsung prevail ?

 

maybe, maybe not changing the prl works on all phones the only problem you mite have is the dial code so try the dial code in my guide if it dosent do anything then you will have to look up how to put ur phone in diagnostics mode i know the samsung transform ultra has a different dial code because i just helped a frien do this last night

so reaserch to find the dial code for your phone if mine dosent work if you cant figure it out ask me an dill see what i can do

 

try this on first i think it will work Dial ##7678#
Enter your MSL
Select DM and your phone should reboot in DM mode
its the one i used on the transform i read it works on the prevail

that is if your phones running gingerbread

 

I may be doing something wrong.. But I downloaded from the link you posted and I installed all the crap.. Now it wont post up the cdma tool. It's asking for an Id and money.. c'mon bro help me out.

 

what do you mean post up and can i have a screenshot of what you see please

 

Never mind. I got frustrated and closed it out and then it popped up what it was supposed to.

 

yeah that happened to my friend when he was doing his transform ive never seen that screen not sure why

 

So I've seen people borrow 3G information from donor phones and put them on other phones, like, umm, the Touch Pro 2. I figure this would help those rebels...

 

I flashed the new Sprint 61085 prl over from the stock 61007 Boost prl and immediately noticed HUGE speed differences. Thank you aenoch. Your instructions and links to the tools worked flawlessly!

 

Where did you find that PRL? THe list i have doesn't show that one listed....can you link the source of PRL files please that you have been using?

 

i updated to the 60687 prl and it seemed to have added at least 100kb/s and this is at home where i barely get signal so i'm going to check how fast it is at work to see if it actually makes a big difference. the cdma signal also seems to be more stable. the file isn't in that link so this is where i found it Sprint released a couple of new PRL's - Android Forums at AndroidCentral.com

 

Awesome worked for me on my warp and my fiances prevail both on 60687 now.

 

I'm just going to throw this out there. I havn't done any regular testing however I have found that the time of day makes a HUGE difference in speed as well. for me I've gone from .15Mbps @ 12:43PM to 1.9Mbps & 131ms (peak) @ 4:50AM that's with stock boost PRL. I'm going to manually update to the 60687 and see how that compares.. Probably won't get another early morning test in because I'm usually asleep at this hour. Ok so I just updated the PRL its now 5:16am and I have reached 2.01mps thats pretty consistent too. that 1.9 from before seemed like a freak accident. The new network graph has a much more stable look / average to it. There is a definate improvement. Very curious to see how this performs in the afternoon. Thanks for the how to aenoch!

 

..... any one know how to get an LG LGL55C Optimus Q into diag mode? cant seem to find it any where and the dial code listed here does not work

 

Works great on the LG Marquee. Didn't even need use the hidden menu when changing prl. Just plug the phone in, set COM port, enter msl in spc box, click the spc blue button and BAM! It picked up my phone and I proceeded to change the prl. Worked like a charm.:thumbup:

Cheers aenoch. Thanks for the TUT.

Special thanks go out to lMonsterl for taking the time to share his wisdom with me and give some pointers. Thx Bro

 

@aenoch Do you mind if I use some of this info to make a tut for people in the Prevail forums? Ill give you all the credit for your work, I just need to change a few things for it to work for the Prevail. Thanks

 

I was going to download cdna tool, but link provided was blocked by norton because it is a known malicious site....
