[EVO 4G General] del818:
This is how I went from 60677 to 01115.

My EVO has been rooted for sometime now running the stock rom. I only rooted so I could use wireless tethering..don't we all......anyway.....I had great speeds on my laptop while tethering. I would also stream movies from Netflix using my PS3..via wi/fi tethering in 3G...(4G not available in my area...approx. 30 east of Austin,TX)....But I took the plunge and flashed Mikfroyo v4.61 and suddenly my wi/fi tethering speeds went to crap. I searched for a solution and I found this.............

Update 3/1/11

New Prl is up 60676

My previous method of update prl, a forced data restore, let handsfree finish at reboot and then cancel auto prl update appears to still effect speeds positively so I suggest doing it that way!

4g connects faster..and maintains for about 10 ft further here at the store.

3g seems less affected by the method above now...4g is a pretty insane difference

simply updating the prl appears to have helped 3g speeds in some locations that previously tested .15-.3 Mbps dl....now testing at .5 Mbps-.7 Mbps ...did they fix the tower or was it the prl? who knows lol.

__________________Your Results May Vary

---There are some areas that have tower issues. This will not fix that. In

these cases notify sprint of the issue and the area.

---You may already be achieving great speeds. The target is 1.0 Mbps

if you already there you may or may not see an improvement.

=---some have reported that updating the prl actually helped their connection. In every single test on my phone updating the prl resulted in the slow speeds seen below. Each phone will be different though so try it without, you can always go back in and update it.

The included HTTP fix is not new...it was suggested by Sprint to fix streaming media issues. While in EPST it is a good idea to change these, though it isn't necessary.

ORIGINAL INFO:

Ok...I stumbled onto something new tonight. For as long as I can remember I have always suggested to update your profile and prl to fix a ton of issues, and if I recall correctly in that order.

After reading multiple posts where manually forcing a data profile reset and changing the proxy settings would't work for some, including myself. I started toying with some things. If you are already achieving speeds of 1 Mbps+ you most likely don;t have an issue, though I have seen one add .5 Mbps to his speeds by following these steps.

This is all assuming you are on the current PRL (as of 03/1/11) 60676

DO NOT UPDATE YOUR PRL

IF YOUR PRL IS UP TO DATE IT IS 60675 as of 2/18/11. This is not doing anything to your PRL. It isn't updating it if you are on 60675, It isn't downgrading it to something else. For some reason THE PROCESS OF UPDATING THE PRL AFTER A DATA UPDATE IS KILLING THE SPEEDS ON SOME PHONES!

If you must update your prl do it in the order I have listed. If you ever update it again, you will have to do this process again.

I have spent two hours testing this on two different roms and the results speak for themselves. I have run through the process over 75 times, updating prl, and not and the results are there EVERY TIME. This should apply to all Evos EXCEPT ASOP.

First Get your MSL

stock: call sprint or use the method I will list later. Sprint will give it to you if you get the right person and ask nicely.

CDMA WORKSHOP METHOD [How To] Retrieve MSL CDMA Workshop Method - xda-developers

Rooted Sense: use msl reader from the market. I added the link. Write this MSL# down, I guarantee you will need it again. Keep it safe.

Rooted ASOP: results may vary but some have had success restoring a sense backup, and then going back to ASOP. Don't wipe.

Download speedtest.net from the market or use Broadband Speed Test my-speedtest(.)com from your phones browser to test your internet speed. Remember to test 3-4 times each time you test.

Update prl first it should be 60675

TURN OFF GPS >Thanks Early Mon

Go to Phone

Type in ##3282#>>>Fixed...sorry for the confusion

Select Edit

Enter MSL

Select Advanced

scroll down to the last two, the http proxy settings and replace the settings with 0 -----------just one zero in each will work fine----------- (I get no credit for this one it iis all over the web)

Change HTTP PD Proxy port from 8085 to 0

Change HTTP PD Proxy address from pd.vog.sprintpcs.com to 0.0.0.0

some say they get better results with 0.0.0.0 so I have decided to do it that way.

This isn't new info...we are just doing this while we are in there. Some have reported a small increase in speeds after doing it...but nothing as significant as what NOT UPDATING the PRL after Data has shown

Use your arrow on your phone to go back

Select Data Profile

Hit Menu

Select restore

Hit OK to reboot...

PAY ATTENTION TO YOUR PHONE

After going through the set up process (Handsfree Activation, LET IF FINISH) you will select ok

YOU HAVE TO HIT CANCEL WHEN IT STARTS LOOKING FOR A PRL UPDATE

YOU HAVE TO HIT CANCEL WHEN IT STARTS LOOKING FOR A PRL UPDATE

Wait for the phone to finish it's thing. 3g Icon should be on, go off, then come back on.

Test speeds.

If I am right...EVERYONE will have speeds like never before. If you update your PRL you will have to do this again..and your speeds will drop to the insanely low speeds again.

Once there is a new software update or PRL update I will update this with any changes. I will most likely edit it further after dinner and clean it up a bit.

POST YOUR RESULTS

If this information is not new I do apologize. I was unaware that the PRL updates were knocking something out of whack with the Profile update. If someone else deserves credit please let me know. I honestly figured this out over the past two hours after trying to find a solution to my internet speeds dropping to completely nothing for most of the day.

DO NOT UPDATE YOUR PRL AFTER DOING THIS!!!!!!!!

It is my belief that this is why most are not seeing the speed increases that others are.

my speeds went from .05-.3 Mbps to 1.5+ MBps download. Upload doesn't change much and varies from .25 Mbps to .7 Mbps

I followed the instructions and after my phone finished activation...my PRL was now 01115......and my tethering speeds are back if not faster than before I flashed Mikfroyo.....................this is my two cents......hope this info helps explain the mystery.....
