Firstly, My understanding is that what this will do is modify the minimum signal strength the phone will connect to down to -110db. When the phone is connected at this signal (-110db) does data still work sufficiently well or does it drop packets?
Secondly, could this same sort of modification be done to the cdma radio?
It works sufficiently well, you will not notice a speed drop at all, you will probably get a small speed increase, but your 4G signal strength will increase drastically if you follow the steps. For the CDMA Radio, you can increase 3G speeds, by following these steps:
1. Know the MSL
2. Dial ##3282#
3. Go to multimedia
4. HTTPPD Proxy Port must be 0
5. HTTPPD Proxy Address must be 0.0.0.0
It may be already done if you have a Custom ROM, but this will boost your 3G speed by about .5 mbps, which is pretty good
When I try to edit the values, my 4G gets disconnected, and the value is not saved.
It does disconnect and reconnect but the values are supposed to stay changed, are you sure you are following the steps completely right?
My phone is stock ROM. Does it need to be rooted or something beforehand?
Yes, I think that might be the problem. My phone is rooted and the values save.
I'm rooted -- DK28 running Truly Epic (ext4)
When I ##3282#, I get a menu with View and Edit.
When I hit Edit, it asks for MSL (which I enter). Then at the bottom, there's a wimax option, but the options after that don't follow your instructions.
When you say 4G radio has to be on, does it have to be actually connected? I'm in an area where I don't get 4G... I'll try it when I get into range later on.
@decalex - yeah I think 4g has to be on before you start the process. I'm not sure you'll get any values if not.
@goku- thanks for this thread. I just did it and noticed a pretty substantial increase in my 4g speed. Before the test, I pulled just around 3.9-4.0mbps on speedtes.net. After I did this, I'm getting around 6.5mbps. Big thanks. I'm on my phone or I would send a thanks your way
Thx has been sent

Yeah, 4G has to be on, and this hack is for places with spotty coverage. Try it when you get in range and see the difference!
When i choose local and type in getprop its just a black screen i can't move it or i don't see the 6 digit number.
You could try "getprop | grep MSL"
That should get you the exact line without having to scroll.
Tried and confirmed working (on rooted stock Eclair). Here in NYC/Queens I never see over 4M down, just did this and got 6.5. I can also get 4G in my basement now. Awesome, and much much props.

do i type it exactly how you typed it?
hey guys on dk28 rooted stock rom I got my msl and then went to do the ##3282# and then i have view and edit and the only option for wimax is view. When I get in after entering my msl I find the two fields and enter the -110 and then the other number and it doesnt keep the values afterwards. should there be 0's in front like what is there now or is it just -110.
Thanks, guys for any help you can give.
Hey guys got it working had to reenter the numbers again back to back didnt take the 1st time just disconnected 4g so just tried it again and they took the 2nd time. so try that if you notice it not taking the values at 1st just put them right back in.
I think I know what you mean. Just type getprop again then hit enter from that black screen and you'll see a ton of lines come up. The msl is located on one of those lines

when i hit enter from the black screen all it does it bring up another little dollar sign.There are no lines at all.I don't know what im doing wrong.
Maybe goku knows. Are you using a virtual keyboard or the physical? I used the physical when I did it. Not that it will definitely work but maybe try both (virtual and physical)?

Ya i tried both keyboards.
So I am assuming that this will negatively effect the battery life, but only if you leave the 4g radio on in either a low 4g signal area or a no 4g signal area, right? Once you are connected, this should have negligible effects on battery life. Or am I mistaken?

What do you all think of this post I found on Androidforums:
Those with worse battery life with Fresh 2.0b
I found a solution!! If you go to settings->About Phone->Battery->Battery Use It will show what items are using your battery. For me if I tapped on Cell standby, time without a signal was at 50%. It accounted for 73% of my battery usage. (Please note that I am using flipz newest radio also)
Here's how to fix it:
Open the dialer
Dial: *#*#4636#*#*
After a second, the testing menu will show up
Tap Phone information
If you scroll down, the preferred network type was defaulted to GSM auto (PRL)
Change it to CDMA only
Time without a signal should change to 0-1%. Also note that the battery use menu is only updated after unplugging the phone from the charger.
Makes sense. Will try it! Thanks!
I am running damagecontrol, and it was already set correctly to CDMA...figured I would just put this out there.
Let me change that...it says "CDMA auto (PRL)"

That isn't even listed for me...But then again I reset my phone this morning, an have been in good signal all day.
mine was at 50% with damageless rom. it was set to CDMA auto (PRL) but i changed it to CDMA only and will see what the result is.... just plugged it in and unplugged it to reset the battery stats....
I've noticed 50-56% as well, Damageless1.0 and it is set properly to CDMA auto (PRL).
ill run the CDMA only on my end
so far so good! I'm on DamageControl v1 set it to cdma only and my battery usage to cell has dropped to 28%! i'll update again later.
Good info......
without Auto PRL, wouldn't we not get the latest and most updated cell tower frequencies? i mean for home locations i guess it what wouldn't really matter, but what about in areas without sprint coverage? how would it know which network to roam on?

Yeah I would assume this would be the case, but that bat increase is pretty decent. I am going to enable it and use it for a day or so around the city.
update: Noticed after a couple reboots my connected time was back up to 50%... I never left my house and i have good coverage here. What gives?
So is this worth doing?

not yet. i mean, make sure you're not set for GSM but CDMA Only isn't helping me -- still always at 50%. Weird.
Probably a radio bug in this firmware

I'm not aware of a Flips radio file? Was this something hidden in that giant Damagecontrol thread?
edit: found it and flashed the radio. Will have to wait to see if this makes any difference. Currently on the suggested "CDMA Only" from this thread.

I'm not notcing any diferent in connect percentage. Still at 50% as others have stated. Battery life seems the same too.
Does anyone else notice that the first day after flashing a rom, the battery life is great? Then the next day it's back to normal. This happens to me with every single rom I upgrade to. Just an observation.
Anyone notice slower dl and ul times lately. This is off of fresh reboot and with full bars on 3g. Did a speed test and dl speed is 144 and upload was 42. Does that seem normal?
Im getting about 780 down and 680 up with 3 bars of 3g

Could there be any apps that i am running that are slowing this down?
I'm in san antonio, texas and I've seen the same thing as the OP. For the first week maybe after I got the phone it was fine ("Full five bars" of 3G --> 1-3Mb down/1Mb up), now it's nightmarishly crappy on 3G, at least where I usually use it. Often around 100kb/down and <50kb up. Sadly, the wimax coverage has also significantly degraded where I usually use it. Used to have fair coverage here and usually 6Mb via a usb dongle, but now you barely get 1Mb down. So, I have to hope it will keep 1 bar of wimax and use that at craptastic ~1mb... but then it falls out of range often and breaks things it's trying to do by switching modems.
On an unrelated issue(the above referred speedtests run from the phone itself and in the case of wimax confirmed with a separate wimax modem matching the phone's performance), I've noticed when using tether for root users (the USB one), that sometimes it seems it will load just a small portion of each webpage, especially when I'm using the 3G connection. Is sprint now packet-sniffing and limiting webpage downloads based on either the browserid or on the size of the file exceeding a certain size? Sometimes after I reboot the phone completely it will work again for a while, but not always.
I also cleated the cookies, cache, and history and have the same problem
Enable EVRC-b.
You will bump it up from 800k to 10200k
They must have intentionally disabled it to lower bandwidth, due to the enormouse data consumtion of this phone.

1) Call Sprint, ask for your MSL. If they refuse, just keep calling and asking, saying you're trying to improve your call quality.
2) Do a Nandroid Backup and a Titanium Backup.
3) Open up your phone's dialer, and punch in ##DATA# (##3282#)
4) Select Edit mode, type in your MSL as the password.
5) Go to Advanced, then for Home Orig change it to EVRC-B or Voice 13K, repeat for Roaming Orig.
6) Just above Home/Roaming Orig, select EVRC-B, and change it to Enable.
7) A little above that is a long string with the abbreviation ACCOLC in it. Change this to 2 (gives you higher priority on the network than normal )
8) Once done, press Menu, then Commit Changes.
9) Let the phone reboot.
10) Reboot into recovery, and do a Nandroid Restore.
The reason for the Nandroid Backup/Restore, is explained here. Basically, there's a software glitch with the program which is launched by ##DATA# and causes apps such as Pandora and pretty much ANY audio streaming app to stop working. By doing a Nandroid Restore, you go back to before the settings editor screwed everything up, but still keep the changes to your baseband.
Seems like Sprint is falling into the same trap as at&t and not upgrading their network. Hopefully speed improves. I've been getting 600 or so down which is pretty pathetic. We will see if it takes sprint as long push out the necessary upgrades.
EVRC-B shouldn't have any effect on your data speed at all. It is the Vocoder for VOICE PHONE CALLS.
ACCOLC changes will have no effect at all. Values of 0-9 have the same priority on the network, they're all equal. Values of 10+ are reserved for high priority government, police/fire/ems, etc type phones and are not accessible to you in this menu. Changing it will do nothing.
I've seen error 67 a few times also withing the past 2 weeks. I wonder if it has anything to do with the new PRL update?
I was getting error 67 for the last two days. Today they stopped but am getting pathetic download speeds. between 10 and 44Kbps.
ALL,
I started this new thread becasue I have swap use my donor phone as htc evo , try to get more speed but it seems not at all. My donor phone most of time lock on EV(evdo) the internat is must more fater than my htc evo(max 128 b) in 1xrtt most of time. from time to time it show 3g but actually speed is very very slow.
Here is my origial setting , was getting 3G icon but speed is around 100-130 b/s
ASEBAND 2.15.00.11.19
KERNEL
2.6.32.17-GEE557FD
HTC-KERNEL at AND18-2#15

After I flash to all kind of rom's and change my kernel, PRL, I am 99% on 1x icon, speed is aver 128k. I can not go back to original configuration since RA issue. Please share some idea how to fix this issue.
reflash radios, flash sense rom and update profile
1: Radio Flahed to : EVO_Radio-2.15.00.05.02_WiMAX-27243_PRI-NV-2.15_003_signed.zip
2: ROM to Calkulin's_EViO_2_ROM_v1.8.zip
3: Lost the signal strength, phone was not stable, able to make outgoing call but not able to receive call. Went to QPST, the system table been alter
it should be automatic but the 1st got altered.
Put RA 2.5.07 back and flash it back to
Android Version 2.2
BaseBand 1.39.00.04.26

3G icon is show up like original but the speed testing is
DL--> 130K
UP--> 144K
Ping time- 700 ms
It is workable when using data compare I went to Android 2.3. so what could be wrong, Can they lock my data rate as 1x ?
I updae profile, same result

Why is it that every single thread that I've read today makes no sense at all? Does the XDA forum have some sort of "garble" function that takes all of the text in a thread and just jumbles it into an illegible mess?
Seriously...Is it that hard for people to take a second, read what they wrote, and correct it so that it doesn't look like a chimpanzee is typing with his feet? Jesus...

After almost one month of debugging and reading, Finally I got EVO working on 3g speed. It is not the rom, not the radio not the kernel. ##786# is the magic, I reset it, let it through with activation first time, does not work, reset it again, cancel activation, put NVRAM back, manually enter HA/AAA, work !

Are you losing signal or having reception problems?
Be careful flashing radios too often. A bad flash equals a bricked phone.

Same issue. I use WiFi so much I hadn't noticed it. I am able to get full WiFi bars though. Maybe the software isn't coding to report a high signal even when it's available? I'll have to test this again while standing/driving next to a cell tower.
If the signal is reporting the same at all times no matter what, it's probably b/c he forgot to add a line to the build.prop
I spotted this in zips' older builds and he fixed it when I told him what it was and what he needed to do

When i first got the phone, i can use the wifi calling whenever I am not in range of a signal or something, like in my basement, but now that i flashed my phone I dont have it, and i dont know where to get it from.
Any help would be appreciated

Just thought I'd share. It's a trick I learned on the Samsung epic OG
No root needed very simple
Go to dialer pad
Enter *#0011#
When the info screen appears hit the menu hard key
You'll see wifi.... Click it
Next you'll see by default powersave mode is enabled. (it sets signal power to 6 out of 10)
Uncheck powersave mode
And that's it. Watch the signal on your wifi in areas where you had maybe 1 bar you'll have 3 now etc.

i see no battery difference at all ive been doing it since the samsung epic. in fact theres a way to allow LTE to connect at a higher decibel than normal (then you'll have LTE at farther distances) but i cant find the proper code yet. its under Entry RX

This is expected IMO. I mean you are physically unchecking "power save" which I believe increases the gain on the amplifier. Unless you are actually suffering from poor wifi signal in an area where there's nothing you can do about it, I would leave it as is. If you're having wifi issues in your home, I would upgrade hardware or add a wifi repeater before messing with the phone.
