4G Issues, Please Help

I have done some searching so please don't flame me, I couldn't find a specific answer.
I live in New Orleans (No 4G yet) but I am currently in Pittsburgh going to have a kidney transplant on Thursday. I really want to get my 4G working since it will be my only source of internet while I am in the hospital.
When I turn 4G on, it constantly cycles "Turning on" and "Turning off"
This is what I am running:
Rooted Evo Hardware Version 0003
Android 2.2
Baseband 2.15.00.11.19
Kernel 2.6.32.17-gee557fd [email protected] #15
Build number Calkulin's EViO 2 ROM v1.7.5
Software 3.70.651.1
PRI Version 1.90_003
PRL 60674
Wimax Version 4.6.2.3v27167
Thanks in advance for any help. I am a bit desperate since I will be in the hospital starting Thursday for about 2 weeks and still in Pittsburgh for about an entire month. I would love to get this working and I think the constant toggle of 4G is going to destroy my battery life and I can't get it to stop.
Thanks again.

I had the same issue and it was because of adfree and an old titanium backup that was corrupt. Mine was doing exactly what yours is but I was on rls5. I know it's not the rom because I am back on it and don't have that problem anymore. I would start from scratch but flash back to a stock rom first to make sure everything goes back to normal. In my case I had a nandroid of stock right when I rooted a few months back. Hope this helps

Thanks, I'm downloading Sprint Lovers right now and am going to give that a try. The last time I flashed, I restored only my apps, not system settings using Titanium. I always do a fresh backup right before I flash.
I've been so excited to try 4G and now I get nothing. Frustrating. I will try your advice and let you know. Thanks again.

here is my guess....
you are in a hospital...
they have some very intensive strong machines that put out so much interferance. most phones have problems getting a good phone singal in a hospital. you maybe fighting non-winalbe battle.
you need to talk to the nurses about alternative connections.

In my case even just installing apps and no data caused the problem. Once I started over again, it went back to normal.
Make sure you update you profile a few times in a row after flashing new roms too. It has been known to cause problems with the radio not connecting.

Thanks but I'm not in the hospital yet, I will be on Thursday. I was driving last night in downtown Pittsburgh where I should be getting a great signal and no 4G.
I will try the sprint lovers with nothing installed or restored and see if I can get 4G to work. I will definitely update my profile a few times to see if that helps. I just checked my RSA key and it is still intact so I'm glad about that.
Going to the store now so I will try it some more while I'm out and about.
Thanks.

Before you do all that, try turning it on with a 4G widget, it worked for me.

Make sure your wifi is off or 4g won't connect, as the phone prefers the fastest connection available.

Ok, progress:
Flashed Sprint Lovers Rom
Got 4G to turn on
Now it scans, attempts to connect to Sprint and does not connect
I checked my MAC and compared it to the 4G MAC under the battery and they match.
Any ideas?

Ok, walked to the window of the hotel and I got it to connect for 1 second then it dropped again and I cannot connect it anymore. I got super excited for the one second though. I don't know why it would not connect on my other rom. The hotel must have something going on to not let it connect so well.

Welcome to the world of 4g. Its great when you've got a good signal and awful when you don't. Coverage is very spotty and large concrete and steel buildings are its enemy. I've been in hotels that I've gotten great coverage and then walk across the hall and nothing. At least you know its working now, hopefully the hospital will have a better signal.

Restoring my apps now and hoping Titanium doesn't blow it up again. I'm going to walk outside in a few minutes (brrrrr) and try it out again. Hopefully I will have better success.

Apps and system settings restored and I still get it to turn on, now it's time to go outside and see if I can connect. It stinks that it wouldn't work with the other rom.
Anyone know if they can connect with OMJ's rom?

in weak 4g signal areas I had better luck connecting with cmwimax 6.1.2 alpha 3, give it a try

I use myn warm RLS5.... and 4g works fine.

Thanks guys, I will check them out.
Thanks for the help everyone, got it to connect in the lobby and download speed was almost 3mb. Then I tested it again and it was .5mb. It is spotty in this hotel so I will try it tomorrow when I am out.

How is this rom, I have tried some CM roms in the past (the ones that don't have 4g working) and they were pretty cool but buggy. I like stable roms.
Let me know, maybe I'll make the change again.

[Q] GPS Trouble result of Solar Flares?

Been having GPS problems for 2 days now.
Trying to figure out if it's my ROM/Kernel setup or this solar flare phenomenon going on.
Anyone else w/GPS problems last few days? I am near Indianapolis.

I am in cincinnati which isn't terribly far from you, and I am having no issues. The only places in the country that should be having issues is down south east? I thought there was some testing going on down there that was supposed to make GPS not work for a few months.

Now that you mention it, I had some problems getting GPS yesterday (one of the few times I've actually needed it.) It would connect, but I would go a quarter mile and lose it. Running MIUI 1.24 with stock kernel. Haven't updated in a little while, but I haven't had the problem before. Was going to Beech Mountain, NC to shred the slopes, but I had this issue before I got into the mountains.

It's possible, the GPS satellites are pretty far out there so they would be more susceptible to it.

I'm wondering if this is a MIUI specific problem. I'm on today's final and have been toying around with different kernels, however the GPS problems started before the new build flash.
Gonna try a different kernel and see how it reacts. I get a lock for a minute and then it drops and flashes the GPS icons back and forth endlessly.
BTW just found a bug in the Savage AOSP 1.6 kernel/MIUI on my 003 hardware. Can't mount SD card. Went back to Savaged-Zen 008 for now.

lol two people doesnt make it the roms fault. i have 0 problems here in pa. been using it a lot. newest version.

[Q] Can I flash a leaked radio?

I have seen on doug piston's site where he has the two official radios for the incredible and two leaked radios from the EVO.
Official VZW Incredible Radios
2.05.00.06.11
2.15.00.07.28
EVO Leaked Radios
2.15.00.09.01
2.15.00.11.19
Is it okay to flash an leaked EVO radio on my phone being that they are two different devices?
I am currently running the 2.15.00.07.28

Yes. Make sure you check the md5 sums after downloading eventhough his links are good. I'm running 11.19 for the past month.

Ok, thanks. I'll give that a try and see what it does for me

I have been running 11.19 on rooted 2.2 for a couple of months and I'm noticing better reception and signal bars in areas I never had bars before. And I can't swear to it, but battery seems to be a tiny bit better.

Okay all went well. But as far as coverage and bars, I'm not seeing a difference. Guess its just the boonies I stay in. Ill give it a few days to settle in, maybe even forget about it being there all together lol

The next time to have to reboot for whatever reason, go ahead and do a battery pull. May not help but definitely can't hurt.

LOS update -- new development

I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.

Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..

I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....

Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug

It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!

Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue

I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......

Time.I have went 3 days without a los then 2 in same day.It is all random

Loss Of Signal When Wifi's In Use?

So, I've had my phone for probably about a year or maybe longer, Rooted it when I first got it, came from an Eris...I flashed a few different ROMs then kinda settled and have been out of it for quite some time now...
But I'm back...and I've got a question, back when I was flashing ROMs often, I couldn't find one that wouldn't drop network connections while using wifi/wifi tether.
Has this issue been resolved? It didn't seem like it was ever a really big issue with most, before, so when I asked about it months ago, no one said much, but I'm hoping now, with newer releases of ROMs someone will have some more info on this issue?
Thanks in advance...
p.s.
currently I'm running TSM Bullet Vivow 1.4 and haven't flashed anything for a good 8 months and I'm gettin buggy and wanna upgrade to something fancy, fast and doesn't drop service...

You need to get a update of your firmware

I'm still a newb on a lot of stuff...how do I go about doing that?

Just google

Are you referring to a radio update? Last I checked, that wasn't the issue and I tried different radios with no results

Kamikaze - I experienced this as well on Bullet, is it while you are on the phone and the call drops out for a few seconds? I think it has to do with the modified boot.img that the port uses.
This is a list of what worked without connection issues for me.
- Unoffical CM9 by Aeroevan
- Nitsuj's stock port for our phone
- Mikrunny (I think but cant remember)

Yeah, it is a problem with ROMs that are ported. The only ROM this doesn't happen on for me is Justin's stock/stock-modified ROM.

I always found that all ported ROMs worked for me because I had the latest OEM radio. But, when I had the leaked ROM for the DINC2 it said to update a radio but I didn't and the WiFi and data signals kept over writing reach other.
So, its just a thing with the radio.

My experience has been less than pleasant with my signal on my Inc2. I have been all over google trying to find a way to boost my signal for the Inc2. I have only had my Inc2 for a few months and just rooted a few weeks ago. Mine problem is not a result of having WiFi on/off, mine is just a week signal period (-95 dBm to -105 dBm). From what I found through my search is people modifying the back cover with foil/copper wire and tape, raising the cleaning the contacts for the antenna, which I have tried all of these as well. I am considering buying a new cover just to see if I can get a better signal as everything I have tried has failed to boost my signal. I have tried *22891 to update my PRL as well as toggling the settings from CDMA only PRL and CDMA/GSM PRL. If anyone finds the magic trick to boost signal strength I am open to other suggestions.

Then I don't have any advice for you. Do you get bad data speeds or drop calls, or is it just the numbers that bother you?

Data speeds are a bit slow but that is not really a problem as I connect to wifi most of the time. The major problem is I get grumbled voices a lot when the signal drops below -100 and I have to change rooms to continue the conversations, only a dropped call from time to time, but I get people telling me they tried to call me but my phone didn't ring and I think that is a result of the low signal strength. I think this is a hardware problem more so then a software/rom issue because a lot of people have an issue with low signal with the Inc2 I found searching on the Verizon forums. I do appreciate you taking time to inquire.

Looking for a lower number would prove challenging unless you are right next to a Verizon tower. I know this because at work we have one on premises and my signal goes to 40 to 60 dbm.
Of course, at home, my signal ranges from 85 to 105 dbm but experience no dropped calls.
Ever since I got my first verizon phone in 2001 the signal quality has mostly measured (on every phone) at approx 85 to 105.
And this is living in two metropolitan cities. I wouldnt give it that much thought unless you are dropping calls. Upgrading the radio is a good idea though as well as PRL after upgrading radio.
Edit: Just realized your post was answered. I would call Verizon and inform them of the call drops and ask them to log them. Could be your unit.

Which rom are you referring to exactly? Link to thread would be nice Thanks!

Yeah, just an update, nothing has cured the issue, updated both firmware and radio with the lastest leak ROM when it came out last month, then switched to different CM ROMs and those were horrible with the toggling of wifi hot spot signal and mobile network, so I went back to bullet and am just living with the random toggling off of wifi/network

I had been bouncing around on alot of the ICS rom's but couldn't seem to find one that this issue was gone. I think it is kernel related.
Since I want my phone to not have this issue I went back to GB for now which for me I didn't want to but this rom works just flawless for me.
GB Sense M 5.0.1 Ext4 Version w/ Drell's #21 Kernel w/ Sense 3 Patch v5.0
Was going to try cm7.2 next since I have always liked non-sense roms.
