Heres is a screenshot.

Which PRL did you use, and what region are you in?

 

[thomasmbl]

how did u do it

 

[ChoDroid]

Were you comparing same location and same time of day?

 

[Lordvincent 90]

Did u by any chance just reboot? I experience those same speeds for 3-7 days after reboot

 

[trenchkato]

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?

 

[ron580]

Which PRL did you use, and what region are you in?

i used sprints 60681 prl im at brownville tx

Were you comparing same location and same time of day?

i tried the same location different times throughout the day getting same speeds

Did u by any chance just reboot? I experience those same speeds for 3-7 days after reboot

to test to see if my tweaks were working i removed all of them rebooted and my speeds were back down to 400kbs. added them back rebooted getting 1300kbs and up

how did u do it

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

 

[dogghouse050]

everything if you can in a dummy tut that would be great

 

[Rally 517]

Yup

 

[ron580]

alright will post up a tut in abit on my first post

 

[Kamel]

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

 

[johnny424]

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

 

[prevailkills]

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?

 

[thomasmbl]

where do i got to get to advanded?

 

[trenchkato]

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]

how do i know which prl i have and can you post the to 3g turbo?

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...

Im trying to manually update my prl and i cant get cdma workshop to work

 

[Nuninablender]

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

 

[Alsaces Daddy]

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...

komajutsu step 1-2 is not necessary if your on gingerbread. to get gingerbread on DM mode for cdma workshop to read it you will have to dial ##port# or ##7678# and select DM your phone will reboot in DM mode and cdma workshop should be able to read the phone now. and do you mind if i copy your tut ill give you all credit ill just add my info in step two. and ill upload my build.prop so you can check it out.
