EVO 4G fully flashed to metropcs, WEAK wifi signal - EVO 4G Q&A, Help & Troubleshooting

Hello,
I have a EVO 4G fully flashed to MetroPCS (talk,txt,mms,web) etc all working properly. But I have one issue: I get barely any reception/bars in my house so the DATA is pretty useless. So I want to use Wifi but Im getting barely any signal from the wifi router that's placed 2 rooms down the hall. I get almost full bars and an excellent signal on my Laptop and my other EVO 4g that's on Sprint.
I looked searched online and found out I'll have to disable DATA so my wifi wont cap off at my data speed. After disabling DATA I still get very weak WiFi signal almost useless with frequent connection drops. I never had weak wifi signal prior to flash on the same phone when it wasnt activated with any service.
Phone is using MetroDroid v2.2 with android 2.2. I dont know why they didnt use metrodroid 3.0...
My question is what's causing weak wifi signal? Is there anything I can do to improve it? Also is there another rom besides the Metro droid that can be fully flashed to MetroPCS with improved wifi?

You can flash any rom you want with out losing metro settings the things the roms change don't affect the partition the settings are on just like radios don't change with a rom flash they are in a seperate partition from the actual files that create the UI and system partitions

The guy that flashed it at the metro place said the flash and all settings will be lost if I flash another ROM. I will have to pay again for the flash and the unlocking etc.

Dude lied to you, you know you coulda flashed it yourself for free right? Hey ill flash a recovery for you for $35 lol j/k the settings are set thru epst I believe in the nvram all that needs to be changed between roms sometimes is the apn settings for MMS and you can use GOSMS Pro and change those on aosp roms or a downgraded epst to change them on a sense rom, there are tons of tutorials on how to flash to metro boost and cricket all over the interwebz and you can find all the info to flash your phone in them

Well i tried to do it myself first following a tutorial on one of the threads here on XDA which also had metroDroid...but when in CDMA workshop my SPC code was showing up as all zeroes. Was also kind of busy so i decided to take it to metro.
Any thoughts on why the wifi signal is so low compared to before when it wasnt activated at all? And if its possible to flash any rom and not lose the flash and data stuff which Rom should i go for? and where exactly can i find instructions to re-do all the stuff?

I've never personally flashed a phone to another carrier but someone who has will stumble in here and help with settings for roms I'd go with the classic by tommytomatoe or mikg 3.0 if you want sense or decks gb rom if you want aosp wifi is probably low due to either a bad flash on your rom or a setting not configured right, before you had it flashed to metro it was probably on sense (I think metrodroid is aosp) and sense shows higher signal strength whereas aosp shows lower signal even tho it's identical the higher signal on sense can trick the connection to stay active even tho its really a weak signal but the speeds will be affected the only settings you will most likely ever screw up would be web and mms and those settings are easily found thru a quick Google search for "evo 4g metropcs web and mms settings"
We are legion, for we are many.

Well well I flashed the classic ROM yesterday and the ROM itself works perfectly fine but i was still having the same issue...so i decided to take the phone apart to mess around with the antenna(s)? I bent them up a little bit and put it back together which result in much better Wifi signal and much better reception and so far i haven't seen signal drop anywhere.
But since I flashed the ROM I still have the web and 3g settings but I messed up the MMS settings. Is there a MMS script i can install/flash for the classic ROM that can get the MMS to work? Or any other method that's not too complicated (I'm a noob). I have tried SMS pro and had no luck.
Will appreciate any thoughts on this. thanks.

Can someone please help?

3g and 1x icons

Ok I don't know if any has this problem but when I'm in a stock Rom I have both 3g and 1x Icons but when I flash a custom Rom I only get the 1x icon why is that it is mind boggling pleas help
I've noticed this occasionally as well, I would think that the stock ROM isn't reporting your signal strength accurately, or something like that.
You do have mobile data on, correct?
From what I read, cannot remember where, this is an issue with cyanogen. You are on 3G when data is enabled but the status icon will remain 1G. Or I have no idea what I am talking about. My phone is reporting the same btw. When I go online I use 4G or Wifi anyway. 7.0.2.1 stock PRL 01115 Baseband 2.15.00.11.19

That does make sense, I had the same issue when I was on Cyanogen.
OP, as long as you don't notice a different in speed and connectivity, then it isn't really a problem, I'm assuming.

Then again better wait till an expert confirms it. I would like to know so I can answer it correctly later on. You could test your speeds with data on in areas you know you do/don't get 3g service and post the results.
yes data is on but if i flash a regular stock rom like the factory but rooted the 3g icon comes up at the start with no problem but if i put some of the fancy roms or any of the 2.3.3 roms i only get the 1x only i dont know why is this i flash and flash and stilll the same crap .....
well i guess no help but im on the new virus kingdom port and mann it is fricken sweet " in my peter griffin voice"
The answer
Try *#*#4636#*#*
Choose Phone Information
Set preferred network type to CDMA only
Back out, your change is saved.
You should see 3g only now, just as you would with a sense rom.

1X data after ROM backups restored

I have been trying different ROMS. Started with Chemistry (with Anthrax kernel) but tried Goodness and then tried The Peoples. Did nandroid backups of each as I went along and noticed at some point that I only had 1X data in The Peoples. So I restored Goodness and only had 1X data. So I restored Chemistry and only had 1X data. I went back to stock (rooted) Sprint Galaxy S3 OTA and got my 3G back BUT I can't get TrevE's wifi hack to work so I'm stuck.
If I can get wifi working I'll be happy (becasue my tablet will connect) but I'd really like to know why my nadroids are not giving me back 3G after restore.
Were you using freezas simple stock rooted, or a custom stock rooted? The reason is that on simple stock rooted, its just the full OTA with root injected, no mods whatsoever
On TPR and Goodness you were seeing "1X" because that's your real signal (the devs have gone into the framework and modded it so that it shows your real signal, 1X when on 1X and 3G when on 3G), whereas on stock (or stock with only root injected) its programmed to tell you that you have 3G whether you have 3G or even when its really only a voice, or 1X, signal. So you haven't actually "gotten your 3G signal back", rather one is telling you that its 3G when in reality its just 1X

Sprint sure makes itself easy to hate. It sure seems like this would be false advertizing. Same with the 4G myth. They present it the LTE BS as if it were everywhere and it simply isn't. Is there an app you would recommend to accurately say what the data speed is?

Nope sorry
I either expect the rom to have it, or I go in and make the edits myself

Edits? Edits to what? Sorry for missing your questions. I DLed the Official Samsung OTA and then rooted it myself. Would freezas simple stock rooted make a difference do you think?

What I mean is edits to the framework so that the 1X indicator shows when I have 1X signal, rather than it showing 3G all the time
But no, freezas stock rooted is the same as what you did so it wouldn't change anything
I don't know of any app that tell you whether you have "1X", "3G" or "4G" signal though

[Q] I need help with my signal!

I have been in many many roms with my galaxy, from Touchwiz to cyanogenmode and liquidsmooth and many others, but one day, I recognize that my signal was really poor. I broke my screen and i replacement by my self i was really careful about didnt touching any other thing that was not part of the screen, but maybe, just maybe i scratch my antenna? There is anyway to check if my signal it's not good as before because of that? Also there are places where i have signal like my house and the speed is really fast, but there are also places where i have full signal and my speed is crap, and there are places were i lose my signal too frequently. I feel like my signal have been deplore slowly. Or it's just.. that sprint LTE is really bad?
first try updating your prl
next if youre on a MD4 TW rom, flash the md4 modem
also try updating your profile
if nothing works try one of the signal refresh apps from the play store
also it may be the rom
if none of the above helps its probably hardware related or it could just be that sprint is upgrading their towers and the one nearest to you is offline for the upgrade...
All AOSP based roms show's your true signal in the noti bar ( Data Bars )
TW JB has an extra signal so it looks like you have good signal but you don't.
Checking signal strength is in
About Phone > Status > Signal Strength.
Usually -75 to -99 is good to really good signal.
But if you think your actual signal is a little far-fetched. Download SpeedTestNET from
Google Play and look at your ups and downs.
My signal is around -80 dbm and my ups are 1 mb and my downs are 3-5 mbs ( It shucks :3 )
There are 3g / Wifi Speed Tweaks you can find around xda or google.
And if it has to come to it, if your on TW JB Rom, Turn off or Freeze your Sprint Connections Optimizer.
That auto connects to frequent used Networks, Wifi Terminals and towers that had the best connections for you before
and sometimes it'll connect to a good tower that's located really far ( I don't know why but I've experienced it... )
Use apps that recalibrate your Radio as well if it helps, A lot of people say it's not worth it, and sometimes it IS just a placebo
and it tricks ya but if it works it works.
Verizon PRL but only for talk.
Hey guys, I was wondering is there a way I can switch to Verizon's towers when I make a call, but only use Sprint's towers for data? didn't want to make a new thread about this in the Q&A since I can't actually post where the Sprint PRLs are yet, but I have horrible reception in my house. I roamed to Verizon's towers constantly when I switched PRLs a couple months ago and I got in trouble because I went over 300MB of data. Thank you all.

it's there is anyway to do that on Cyanogenmode or an AOSP rom?
sadly no... but your signal might be because your on an aosp rom... they arent as stable as touchwiz roms...
There's a few unofficial ported AOSP roms that have the sprint update feature, I'm not to sure which ones but i've seen them.
They only updates profile, im not to sure about PRL. It's best to update on a TW based Rom because it's easier, it takes
awhile switching between the two just to update though.
On a stock TW JB Rom, on home screen press your menu button.
Select Settings or System Settings.
Scroll all the way down and select System Updates.
Select Update PRL.
Wait for it to be done.
Select Update Profile.
Wait for that to be done.
Reboot your phone.
Make sure your data is connected, if it's slow be patient let it take time to update Profile and PRL.
Noted that as long as your on the Rom based on what firmware it is. ICS or JB. It doesn't matter which
modem you choose, just as long as its based on one or the other.
For example. Being on an MD4 Rom you'll still be able to have 3g / 4GLTE Data with an LJ7 Modem, or
LI3 rom with an LF9 modem. Remember changing your modem YMMV, or Your Mileage May Vary, almost everyone
who switches modems that have the best stability for them they either have better data speeds. Or They're not
being dropped as often or not at all when near a tower.
For me, around my area, using an MD4 Rom, I'm using the LJ7 modem, because all the other modems I have tried either
dropped my data ( Not connected to towers even though there's one near me. ) Or I'd have to reboot my phone just to get it back.
and when im on an AOSP Rom, I'm usually using LF9, Because i've tested my data speeds on it and that's the highest out of all i've used
+ I don't get my data cut off or dropped.
@ eisawi99
Most AOSP Roms have 3G and WiFi tweaks to help with stability. But the downer part of using AOSP Roms is it doesn't get along with
trying to connect to 4G LTE, I have 4G LTE in my area, when using a TW rom it'll instantly connect when ever it's got a strong signal.
While on an AOSP Rom, It rarely ever does even if im almost sitting next to it.
Sometimes it's also the APN's that are being configured via script tweaks. I usually just remove all my old APN's and use all of sprint's
APNs when ever i can't send or recieve a text or mms, but it'll also help with data connection stability too.

[Q] Not getting certain signals?

Hi, it's been a while since I posted on the forums. I've had a problem with this for a while now, but never bothered to ask you all. i don't get certain types of signal with the stock rom and aosp roms. For stock, I get 4g data, and I am able to make calls while roaming but not while I am on regular 1x (connects but I can't use it). Also, signal is iffy, sometimes it connects/randomly disconnects. For aosp, I get almost no signal, only roaming. I think that I didn't mess up my efs folder, my imei is still the same as the DEX on the back of my phone. Do you guys know what is wrong or how to fix this? I want to be able to use my phone again...
What modem are you on? Firmware or ROM? I'm using NE2 with rwilco's stock ROM and a GSM sph-l900 with t-mobile... I get 3G and 4G (hsdpa+)... before I use to get lte/3g/1x and I use roam control when I'm in an area where I know I don't have a good signal...

4G Disappeared

I flashed the Lollipop version of Liquid Smooth on my AT&T G3 and at first everything was working fine, 4G included. After a couple of days 4G disappeared. When this happened it didn't just go to 3G, it lost all data service completely. I originally figured it was the ROM and flashed back to the previous ROM I had using the TWRP backup I made beforehand. Same story, no data service. Figured maybe it was the modem so I flashed a working G3 modem on here, same story. I flashed to a different Lollipop ROM, Resurrection, to see if that fixed anything, nope. This is the ROM I currently have installed. At this point I went and look at the mobile network options and immediately noticed 1 issue, the preferred service was 3G and not LTE. I had an option to change it to LTE but when I actually select LTE it doesn't actually switch, it just stays on 3G.
The one good thing I managed to do was switch the APN to one that worked with 3G. The APN that was originally set was "pta", I can provide the actual APN information if that'll be useful but I figure most ROMs are going to have similarly named APNs. 3G works on at least 2 of the APNs listed for this ROM, "broadband" and "wap.cingular".
I called AT&T and determined that I my 4G service wasn't cut off; not that I really thought it was anyway as that wouldn't explain why I can't even select 4G as a network type. I'm kind of at a loss as to how I just randomly lost 4G access without actually making any changes to the firmware or OS of the phone. I'm also at a loss of how I can get it back.
And I am just sitting here with 3G with speed of 2 Mbps...
No one has any ideas or advice?
