Did u by any chance just reboot? I experience those same speeds for 3-7 days after reboot
 
My question is about 4gv vocoder. A quick google search told me what it was and what it does. But how do you go about enabling it?

if you guys want i could make a tut but what would u want me to explain changing prl,enabling 4gv or the build.prop lines i added
 
Thanks in advance for this!!! I really hope to improve my 3g speeds, they have been a bit of pain in some applications.

If I can get 1.5mbps with your tweaks, I will gladly donate to you so leave a paypal link
 
best i think i have seen my phone do is....down 2482kbps ...up 829 kbps

that was when i was away on work on the coast (east) md ...evening time like 9 pm

when i got home a few days later tried again...down 186kbps...up 77kbps

the second time was same time of evening 9 pm but only between 1 and 2 bars of service

why such a drastic change? i mean i think the drop off in service has alot to do with it but ..thats huge
 
did the 4gv thing and my phone wont even boot fully i get fc's left and right and it wont fully start up. fc fc fc fc fc fc fc fc fc wtf!?



nevermind got it

did speed test before and after....before 999down 200up.....after 949down 186up same location hmmmmmm

yeah this should not effect boot at all 4gv is just a vocoder. how many tests did u run and did you choose a close server?are you running a boost prl?
 
I have no access to the hidden menu because I am running Hroarks Cm7 however I was able to get 2.18 Megs down using the 3g Turbocharger set to expiremental... Prl 60683 (with full service of course) ((and knowing boost full service is hard to come by in residential districts))

how do i know which prl i have and can you post the link to 3g turbo?
 
trenchkato said:
go to settings > about phone > status .... If you dont know which prl you are on you are probably on the boost default one... changing to a sprint one (any sprint one) increased my service.. especially at home...

thanks i just updated prl but its 61007 how do i get a different one or is this one ok. sorry for 20 questions still pretty new to this stuff
 
Having issues updating from a Boost PRL to a Sprint PRL, CDMA workshop won't read my phone at all, tried everything like suggested, device manager has two Samsung usb and modem devices listed, only one had a COM port assigned (8). Would connect but nothing otherwise.. Any suggestions? Or is there another way to manually change the PRL? Like some phones can actually just do it from a hidden menu
 
From step one to end would be Great for a tut. I am runnin Kuma Kournal, CTmod 2.3. I live upstate new york and running the stock boost prl and have no clue how to change it although I have seen a few steps saying how to do it, but not really understanding...:confused:
