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] Wanting to flash new radio on the Tmobile G2.

I want to flash a new radio to my T-Mobile G2 but i am Really scared on which one i can and cannot flash because they can brick my phone. Any Suggestions and or comments/advice? I have read over the offical Radio Thread and cannot find anything to specify which is which. Thanks in advance
-Chris

Im fairly certain that all the radios so far in the Radio Thread can be used with the G2, I myself have used these three:
Vision_RADIO_12.28e.60.140f_26.04.02.17( best results for me with this one)
Vision_RADIO_12.28b.60.140e_26.03.02.26
Vision_TMOUS_RADIO_12.21.60.09b_26.02.01.15 (G2)

don't worry as long as you have prem root and s-off with eng-hboot you should be fine flashing a radio. I was able to flash it using PC10IMG way and it worked fine lol

Thanks for the quick response! Is "Vision_RADIO_12.28e.60.140f_26.04.02.17" the best one so far to use? I just flashed it and everything went okay but i cant really see if it improved anything.... :/

Well there's a new one out but its not posted in the offical radio thread yet (maybe it is haven't check yet lol). Well for me I mainly saw a diffrence with the signal bar never going to zero. Most of the time its 1-3 bars at the 1st floor of my house and on the second floor I get about full bars at the most. Oh yea for some reason I saw that my wifi was stronger to but don't know if the radio fixed that to

I flashed the new radio and RiL files, this was about a week ago and I have to say the battery life as well as the signal and data is far better. The GPS is more stable than ever. I am one happy noob. LOL Thanks for the instructions and the links.
This is the radio I use
Vision_RADIO_12.28e.60.140f_26.04.02.17( best results for me with this one)

Been there done that. Messes with your network connectivity. Don't do that. Stick with stock radio.

Whether a particular radio improves reception (and therefore battery drain) or hurts it, often depends on your local geography. Newer radios often have other fixes as well, so they are a good place to start. But its usually more trial and error, and there is no overall "best" or "better" radio.
Also, there is not one "stock" radio. It depends on what version of the phone you have, what region/carrier, and when you got your phone. There are often different radios for different carriers, and each carrier usually gets a radio updates, which then get installed on the phones as they ship.
If you don't understand these concepts, you probably should not be flashing any radios on your phone to begin with.

Your better off going to this thread for RADIO'S http://forum.xda-developers.com/showthread.php?t=970809
All the links in the 2nd post above are megaupload and there's only a few radio's more have surfaced over time.

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.
Sent from my SPH-D710 using xda premium

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

[Q] Which rollback PC36IMG to return to stock, then reroot?

latest questions were in june, so im going to ask to get a more recent suggestion.
im having signal problems no matter where i go, and i live in between 2 towers close by, one has 4g and im getting about ~1500kbps when i should be getting over 5k. 3G speeds are 10-60kbps down, market times out, and internet is useless.
Ive been doing alot of flashing of different roms, dunno if something messed up my phone, or an internal hardware problem, or what.. but i shouldnt be getting piss poor signal and speeds on ALL roms. Ive updated latest radio, and did all that extra crap. Same poor results.
so for a peace of mind, i'd like to flash an official sprint pc36img that includes radios, pri,prl, etc Then i'd like to root that, install amon ra, and flash synergy rls1 again. So that way im having a new fresh start and i can rule that out.
thanks.
EDIT: should i use unrevoked, or unrevoked forever?

Whether you are rooted or not, makes no difference on any problems with the radios. You do not need to unroot to fix it.
What you need to do, it to flash a stock ROM, about the time that you purchased the phone, then flash the radios from that time period as well, then you can flash up to the current radio files and whatever ROM/Kernel you want to use.
There is a full list of Radio Files, Recoveries, Stock ROMs, RUU files etc in the stickies of this forum.
Simple Search works well too.

Welcome to sprint. As stated above, there is nothing you can do about it, the network just sucks. I haven't gotten above 100kbps on 3g in over a year, and I live less than a block from a sprint tower.

thanks guys.. yea its a tower issue, i rolled back like suggested, flashed radios, etc etc.. same shyt signal. local tower is under maintenance.

Weak signal in my house and other areas?

I've been having a lot of 3G connectivity issues in my house, and a lot of the times outdoors. I've tried CM7 and CM9 all with different kernels. I'm using the 2.15.10.12.20. I've also tried *228
Should I try a different radio? I've tried even using a network refresh to no avail. What should I try?

Try different radios, you can get them here http://dinc.does-it.net/radios. The evo radios on that page also work for the inc, as evos and incs are so alike.

No it does not make it the best. When it comes to radios its a what works best for me may not work best for you type deal. Many people report that they get the best signal on older radios. For me the newest radio is the best signal i have ever got, while others say it made there signal worse.

So I've tried a number of radios, with little improvement, if any at all. I've tried *228 and even tried a signal refresher. However, I still have poor signal, while my friends with other phones do not.
Any advice?

It may just be that your friends have newer radio hardware as their phones are newer. If new radio software or *228 dosent help, there isnt really anything else you can do .

Really? Are you sure it might not be a defect? I mean it is a refurb I got after my first one broke. Or is it one of those things where it either works or doesn't work?

12.20 was the worst radio I ever used, I can't believe that verizon pushed that to all dinc users last month who were on stock. I've been using the EVO 12.19 radio and it seems to be the best for my phone but like everyone says it varies. I would keep trying some of the other radios until you find something a little better. I recommend trying 07.28 and 07.07, Particularly 07.07 if your phone had better reception about a month ago. If you got the replacement more recently than that then i guess it would be hard to tell but you can still try it. 07.28 is a froyo radio but I had it for a very long time before i realized that when I downgraded to root I also had downgraded my radio and it worked just fine. Anyway, best of luck to you but if none of these helps, more than likely, like cmlusco said, it might be time for a new phone. You can buy used phones for fairly cheap online so you won't have to wait until your contract is up.

I get an upgrade the end of August! Just the wait will kill me

Hey guys just a heads up. Verizon sent me another Incredible and it fixed all my issues. I now dropped from -105 to -85. Thanks again!
