Very bad to no signal atall?!!!

Hey guys,
After rooting my evo about 4 months back ive neen through many roms, kernels etc. I have only updated the radio and pri once recently but never touched the winmax but recently ive noticed horrible signal strength sometimes texts wont even go through and im getting around 1-2 bars max no matter if im at or out somwhere.
So my question is what should I do to improve this would updating wimax help? Since ive never updated it since I bought this phone.
Im on cyanogen b2 supersonic mod which I flashed over a nightly because thats what da instructiins said.
Kernel: snap 7.6 turbo

if its just recently i would see if any friends have signal issues in the same areas... could be a tower issue.
otherwise i would go back to a stock 2.2 odex (it will jave latest wimax and radio in it.) and see if that helps.
if nothing works... it very well could br your phone.

Updating the WiMax radio will have nothing to do with your 3G/voice reception. That's a totally separate radio.
+1 on v_lestat's suggestion. See if anyone else is having problems, if they aren't I would try these steps (continuing on to the next if the previous didn't work).
1. Update profile
2. Reset profile in epst ##3282# (Need MSL) Edit Mode>Data Profile>Menu>Restore
3. Experiment with different radios until you find one that works best in your area.

Thanks for thr reply but can you explain in a little bit of detail like what will the epst do? And whats "MSL" lol

I saw someone post something today about a program on the market to get your msl. It's called MSL reader and will help you get that. You cannot edit details in the epst without it. If that doesnt' work, you can always call sprint and tell them you need it. There are a couple of threads on here for help if they aren't willing to give it to you.
In the epst you can change things pertaining to your data pofile, wimax settings, and misc advanced settings. DO NOT CHANGE ANYTHING IN HERE UNLESS YOU KNOW WHAT YOU ARE CHANGING. For what you need to do, just reset your user profile and then click OK to restart your phone.

Flashed CM7 and Stuck in 1x RTT? [Possible Solution]

I recently received a 004 hardware rev Evo with the latest HBoot. After rooting and flashing CM7RC0 (thank you Lithid) I found myself stuck in 1x RTT mode. Switching back to a Sense restored and enabled 3G once more. Going back to CM7, I once again would be stuck in 1x RTT.
The following solved my issue.
Flash a Sense based ROM to access ## codes and ...
1. ##3282#
2. Edit Mode
3. Enter MSL
4. EVDO
5. Preferred Mode
6. Set it to Automatic
7. Press Menu and commit modifications
8. Reboot
At this point you may go back and/or restore CM7 and 3G should be enabled.
To others stuck in 1xRTT mode in CM7, I post here hoping it helps others as it did me.

You win.

May be old, but just tried this on my Shift and worked like a charm. Happily now running 3G on CM7, thanks!

I switched to SalvageMod and I am having the same issue.
I will try this later tonight.

Just did this, phone is rebooting now.
Was interesting tho, EVDO was set to 'CDMA', hopefully now that it's set to 'Auto' I will get better speeds and actually get 3G while on my GB ROM.

Holy **** it actually worked. Excuse my language.
Before I was hitting MAX 300kbps down over "3g" on Sense and 1xRTT on SalvageMod.
Did the fix and now Im getting true 3G and hitting 1-1.6Mbit down and around 0.5Mbit up.
Thank you thank you thank you!!!!

So, I dont know if Im imagining things, but it seems like I have worse battery life after doing this. Any ideas?

I actually was locked on 1x RTT after I spent some time on one of the CM7 nightlies. Even after I flashed a number of Sense ROMs I was still locked, at that point I figured it was my old phone and so I got a replacement, I wish I had seen this first.

Yep, pretty sure battery is suffering now.

Or you could just download network from the market. Easier than flashing a sense Rom and going back.
Also the battery drain is from changing it from cdma. That was one of the battery fixes for the evo, to change it to cdma, most people did it after rooting their phones. Now you are changing also affecting battery life.

I cant find an app simply called "Network"

So network kinda broke my 3g, switched to cdma to try it out, then back to "auto". 3g icon is back but my data speeds are not

flashing to a sense rom right now to try this. Im on a 004 Evo as well running the latest MIUI and I noticed theres now way i can drive around from VA - Boston and not switch from 1x to 3g atleast once... hopefully this will change that.

Thank you! If this works it'll prove that it was an issue in AOSP ROM's. I was tired of people saying that Sense ROM's don't show true signal. It was a load of B.S. and I knew it was something else because I would flip between UD, CM, etc and it would still have the same issue.
Nice find dude. This should be a sticky or added to AOSP ROM releases until they can find out what's causing the issue in the ROM itself.

ok so i just implemented the fix. switching back to MiUI to see if it worked.
edit: now shows when i have 3g thanks. im guessing the extra battery drain is due to it now switching from 3g to 1x now. or constantly scanning?

Thanks a lot, finally can flash CM7 again.

Help......CM7

After I flash this ROM my phone decides it dosent want to obtain a 3G signal and it will not connect to my home network which has excellent signal but instead wants to connect to random open extremley weak networks. Im getting beyond irritated!

Are you running the latest cm7 nightly #36? Why don't you turn on airplane mode then turn it off to see if that fixes it. Is your router a wireless n? If it is make sure its on 2.5 ghz and not 5.0ghz. Reason I said that is because my router can broadcast 2.5 and 5.0 so I have to make sure its 2.5 only.

Flash newest radio updates and update prl. Idk bout the wifi
A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.

I cant even sync my google account now cause I cant hold a solid 3G or get wifi going.....Ive been updating my profile and PRL. I did the GPSCLR and I dont know if I have the newest radio.... Im just ready to body slam this phone...It was working until I had CM7 flashed and then got a bootloop and had to go back.....

Wow this sounds super strange. Why don't you try going into a sense rom to verify its not your account/phone and then come back to cm7! Maybe sprints network is down. Before you come back to cm7 update your profile a few times. As wifi goes you should get the free wifi analyzer app in the market to see what's the deal with your wifi.
Do you have an airave in your home?

I dont know what to do I went back to the backup I created. It finally let me setup my google account... I really dont understand this.

Read through this thread and make sure you're up to date with wimax, pri,prl, etc.
http://forum.xda-developers.com/showthread.php?t=715485
Please make sure you have a back up of your wimax keys before you do anything. The moment is terrible and can't even come close to being placed in the same sentence with the evo. I'm trying to understand whats going on but u need to give a little more details.

[Q] My dl speed on 3g at home is 133kbs my gf is 1Mps in same house same phone.

I have a rooted evo using one of about ten roms depending and my gf is unrooted. Now we live in 3g only area and her phone probably has never been in a 4g area where mine is everyday when I go to work. I've tried everything I know to try. The media stream fix, the throttle cap fix on various roms, have the most recent radios and such. Even done the combo package to make certain i have the latest stuff. I'm using prl 01115, 1.90_003,3.70.651.1 and 2.15.00.11.19 on hardware version 0003. Used unrevoked and doesn't matter which bu clockwork up until month ago then used amon ra. I get almost an exact download speed after 100 tests over period of a few weeks at around 133kps. My gf unrooted evo using identical phone with at least week of tests she gets on average about 1Mps. My 4g speeds at work are awesome. Even during the busy period of the day I get 6Mps. I've got as many as 10 to 12 late at night. Get the standard upload as well. I'm out of options? Please help.....i'm past the nob stage i suppose to a rookie, but i catch on if explained as far as extensive stuff goes. Change roms, kernels, boot animations and basic themes and mods are where my experience ends. Any advice?

do you guys have the same PRL and pri? that could account for differences in speed

Yes....doesn't matter if they aren't the same we still get same speeds pretty much, but yes they are the same. A little more info for you. We have same settings as far as roaming etc etc. That isn't it. There is one tower specifically we use. Kinda small town and that tower covers city limits pretty much. There is another by the interstate way the other direction but i'm dead certain we use the same tower. Get about three quarters to almost full signal on both phones in same areas good or bad. Another issue is and I hate to say this, but dude I use my phone alot. I stay online with it god knows how much. Lets just say I use my no cap data like a mofo. My gf however is a sprint data dream. Pays for extra data never in 4g and most blackberry users use more data. Dunno?

anyone else?

I dont put much stock in speed tests, benchmarks etc.... My wife, daughterr and myself all have evos and I've tested all of them and they're all different. Of course mine is the fastest because I'm special...

Sounds like what happened to me. What PRL are both of you running?

I understand what your saying guy, but over a period of two weeks at least five tests per day and they all are within 100 kbs of each other in results and her phone avg is 1.2Mps and mine is 133kbs. Dude that is a HUGE difference. Either i'm being throttled or something is wrong with my phone, but what? I've reset and updated and done every possible thing I can to improve it and no matter what I do my avg speed stays around the same or is zero. I might add that i've done this using several different speed test sites. I range from 120 to 140. I'm out of possibilites. I need help from someone that knows more than me for sure.

We are both running latest. Both phones were updated to the latest prl couple days ago.

I believe some of us are being throttled, to heck with the naysayers! Do you have root explorer? If so try this....
Open Root Explorer
Select DATA
Select SYSTEM
Select THROTTLE, Delete this File/Folder and in a minute or so run speed test again (a few times).
Your speeds should increase, mine do, I go from .200 down to 1.3 down! BUT, the file will rebuild itself within 5 minutes or so, once it does my speeds are back to .200 down. The way around this for me was to use a Hacked PRL #00001 found HERE. This will have you as roaming, but if you use WiFi as much as possible, dont tether your PC to download Torrents, it should be OK. I havent seen where anyone has been canceled from using this Hack, yet anyway

cool....gonna give it a try. be back in few and give results.

Or you could just downgrade your prl like me. I went back to 60675 and dl speed s are back up

Fix: I dont take the credit, but just letting you know.
First, I downloaded the sprint PRL's from this thread (http://forum.xda-developers.com/showthread.php?t=1029900)(thanks to cordell12)
They should be in the second post. After downloading, unzip them onto the root of your SD cards.
Then, download the EPST.apk (I have attached it). In Android 2.2, they removed the ##775# PRL functionality, and this .apk will give the functionality back. Download the .apk and move it to system/app folder using root explorer. Tap to install.
After it installs, go to a dialer (you need to have a sense on I believe) and press ##775#. It will prompt you to enter your MSL.
After entering the MSL, it should take you to a screen with the "Update PRL" option. Click it. After a few seconds, it should bring up all the .prl files you have (you unzipped them earlier). Choose the 60677.prl file. Click ok.
Press the menu capcitive button, and click "Commit Modifications". The phone will automatically reboot.
P.S. Can you test your speed and tell me if it worked?

Sorry...Easter bunny showed up for my gf lil girl. Ok I'm here on my Evo on stock browser lil slow.

Just follow what I said earlier...it worked for me

Mine will vary from a .200 to 1.0 increase (depending on time of day) just from deleting that file. I tried to change permissions on the file and when it went to do whatever it does I got sent into a never ending bootloop It took a nandroid to bring me back!

Are the ROMs your running AOSP?
If so, flash to a sense rom and update prl and and profile.
I had a huge drop. from 1.3mb to 300kb, because id been on AOSP for so long and had ignored my profile, i was only two prls behind, profile can help alot

After updating my PRL my 3g data speeds were pretty bad, sounds the same as your problem. I did this and it fixed it right up, back to normal now.

[Q] 1x problems

my evo when I flash custom roms will always give me 1x instead of 3g icon... not sure why is there a fix of any kind?

Your probably not clearing everything when you flash the rom. Make sure you wipe everything when flashing a new rom.

Try going into espt. (you need to be on a sense rom) Enter ##3282#. Go to edit mode (you'll need your MSL number). Select 'evdo', and make sure that the preferred mode is set to automatic. I don't remember if it automatically reboots your phone when you commit the changes, but if not, then reboot it manually after you change it. That may help ya out.

Good call, only reason I didn't think this was the reason because most roms don't have the icon change when you lose evdo.

Right, but now that a lot of the Sense roms are incorporating that mod (the mod that shows if your truly on 3g or 1xx), some people are realizing that they aren't getting 3g signal at all. Some may have been on 1x the entire time, but then when they switch to a rom that shows what you're actually connected to, they realtize they're on 1x. That trick works for some people, but not all. I think it'll help out though.

Same 1x problem no matter what i do
Ive had this problem for about 5 months now and it doesnt matter what ROM i switch to or use it the same and going in EPST doesnt fix the problem neither when doing what you just said to do with the epst but when i do change it from AUTOMATIC to HRC it goes back on 3G but the downfall to that is that phone calls and text dont come in to your phone until you make a phone call so can anyone help solve the issue why is this happening? I have a white evo hardwhere 0003 used all kind of roms even stock and same thing and know alot about phones and been messing with them since windows mobile 6.1 HTC TOUCH for sprint soo... And my girls evo is and stays on 3GrevA. her in not rooted and is stock tho while mines is stuck eternally 1xrtt.

This. There may not be anything really wrong at all. I mean, it sucks to drop to 1X, but the stock ROM was lying to you.
Now, if you ONLY see 1X all the time, yeah, that's a problem. But an occasional switch over to 1X (particularly if you're in a tough signal area, like the core of an office building) is normal.

I am on mikG Rom I have had 3g before I updated radios got the new stock rom but at home I use a airwave for signal wonder if that messes anything up?

Have you tried one of the new Sense 3 roms? The reason I ask...when you go into 'ABOUT PHONE' in settings these versions give you a network option that others do not. Check to see what it is telling you are receiving 1X or evdo. If it says 1X...you may have the same issue I had...borked 3G. Once I got it replaced..I loaded up the 3.0 again just to check what it now said..and you betcha...evdo was now showing and not 1Xrxx (or whatever it was).
I tried everything as well for about three weeks..you name it..ROMS/RADIOS/STOCK/CUSTOM/ESPT even took it back to fully stock and then rooted again (lost my .76Hboot in doing so, but phone didn't work right anyway... I was grabbing for straws. Luckily it was just under the first year and paid the 35 to have it replaced (no warranty plan). I travel and no matter where I went the speeds were terrible..ya..the 1X/3G/EVDO in the notifications bar is just for looks...but you KNOW when your stuck on 1X...frustrating.
This may not be the case....but

kinda of a simple fix... first of all stock sense roms always show 3g even if you dont have it... if on every rom you flash you keep getting the 1x AND you alreeady tried radios, nv etc upgrades and those dont work, then it is your PRL not PRI... 2 different things... to fix it check out a thread under deveopement ..Deck.... cause there is a fix there, or google prl and pri update evo on google.. you will need msl and be on sense and be able to use espt
