bad signal related to the radio version?

So I decided to Root, S-Off and flash Coredroid v4.7 on my Inspire, but I leave it with the stock radio (12.39.60.19P_26.06.04.06_M), but the signal seems pretty weak even on places where my Nexus one was at full strength my Inspire seems to only be able to grab 2 bars at much, and the WiFI connection seems week too, on my N1 I used to be able to get full signal from more than 20 meters, but my Inspire seems to lose it after 15 meters.
I read some posts and other blogs/forums and some attribute those issues to the radio version, so I hope someone can give me an opinion and tell me if I should Update the radio and to which version if so.
Thanks in advance.

Try this
For phone signal, try *#*#4636#*#* in the dialer. This will bring up a screen that has 5 options, I went to phone and scroll to the bottom. Under the preferred network I changed it to GSM only as its an AT&T phone anyway, I was getting 1 or 2 bars at home and was missing calls left and right. after setting this, back out and shut the phone down then restart. I have all 4 bars now. It would also eat the battery, mine was on WCDMA preferred and I think it was searching for that signal constantly. There is a screen for wifi also but there is nothing adjustable there.

Odd that it would have WCDMA preferred as default. I just adjusted this as well and it improved the signal in my office. Good catch.

Gsm only does not work for me, my lame carrier runs on gsm but their mobile internet runs on their 3g so I need to connect to both. Setting it to wcdma/gsm auto seems to have improved the signal

Hey all, I'm on AT&T running radio 26.06.04.06_M. Any specific recommendations? GSM/CDMA Auto (PRL) seems to give me the best service based on bars, but that doesn't necessarily mean much (I'm on an HSDPA connection with 3/4 fluctuating right now).
Also, I think I might not have HSUPA enabled with this radio, I'm only getting .56Mbps upload and around a 2.79 download (Whereas on standard 3G with my old iPhone I typically pulled around a 1.2). HSDPA is without a doubt enabled and it shows that I'm connected on that network, but is there a better radio I should try out?

Is it just this phone that shows roaming? Any other at&t phones near you? what do they show?

is their any way to check if your actually roaming because im not getting edge like i always do at my house and i never am on roaming

I guess you can look at your online account or call at&t. Does it show roaming just in one area? Only indoors?

im not in a place that i ever roam, i think it's something that I'M missing because this happens on all my ROM's and i can't fix it by any traditional method so i think that im just missing something that i have to flash

*#*#4636#*#* in dialer, then select "Phone info" and you'll get a lot more detail (including roaming, network type, etc.).

it says that my current network is AT&T but that its roaming and it's saying that i have edge but i still don't know if it's charging me roaming charges and how to get back to the normal status info

How long has this been going on? I would say go back to a stock ROM and see if it fixes it.
Also, are you following this method to flash your ROMs?

it has always fixed it when i go to the stock rom but i need to know how to get it fixed with other rom's

should i change my NTP server address for the GPS because i changed that immediately after flashing and it says north-american.pool.ntp.org and i dont know if thats for canada

thats not the problem but it has to do with the radio so can anyone tell me where the stock AT&T radio is that the Inspire came with because i tried the one in the hack kit but i didnt understand how to flash it

Just put on airplane mode and turn it back off. Boom your done.

Kind of cool. Mine showed the first option chosen but it hope between 3G and 4G as usual. Choosing LTE made no difference for me. I have virtually no 4g signal where I love

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.

With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.

Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.
Sent from my SCH-I535 using xda app-developers app

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?

When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days

Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.

I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.

Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

send it back
I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Your new phone came with an already updated firmware version I535VRALG1 instead of the original version I535VRALF2.

Did you get the "No Sim Card" notification and "No Network Connection" message?

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"

[Q] LTE on CM10 tried everything

For some reason I cannot get LTE to work at all on CM10. I've done everything and it still wont work at all. I tried reverting back to stock rom, and when I did, LTE worked. So I thought if I went back to CM10 from stock it would resolve the issue, but it did not. I've checked my APNs and I cannot change the preferred network mode and i tried *#*#info#*#* and i can't change anything there to anything that has LTE on it. I'm not sure if it's just a problem with the ROM or what, but I've done plenty of researched, searched all the forums, and can't find anything that will fix.
Additional information:
Im in ATT
I've tried all the radios
and I AM in an LTE area.

Ok, try different apn. Which cm10 are you trying to use?

Does the problem happen on other ROMs? I'm not saying to use a different ROM, just saying that if it doesn't happen on, say, AOKP or Orthus (both CM-based), it's probably an issue with how CM10 is configured on your phone.

If you go into network operators (settings -network)and select att it will allow to change modes.

Haha yeah most of the time this setting is overlooked and this option enables you to turn off LTE if you want (which you don't have to have a RAT unlocked modem as presumed) and if you go to *#*#4636#*#* on your dialer you can have it set to LTE only as well.

I have the exact same issues. I've done everything on this post plus done all the research as well. For my problem whenever I enter an LTE area my data service completely drops for about 5 seconds and then when it connects it only shows HSPA+. I have never been able to pick up LTE. When I was on CM9.1 I had no issues at all. LTE connected with no issues. So is this a CM10 issue or a phone issue?

try this, might help, might not, make a backup, if you have more than one apn, remove all apn's except your lte apn(ATT Pta, for rogers :ltemobile), restart phone
edit: of course make sure it was set to the lte apn in the first place, if it was and still have probs, do above procedure if you have more than one apn

For some reason my APN was not set to the lte one (ATT Pta). I changed it to that. Hopefully that fixes my problem. Thanks for the help!

I have a slightly different problem. I am running the latest cm10 nightly and notice that any time I get lucky and go into a 4g coverage area I can only make phone calls. No data transfers at all. I have my APN set to ATT LTE pta which I assumed is the right selection. Im normally in a A3g(HSPA)~700-17 coverage area. Is this the wrong APN to use?

Yup. I have HSPA/HSPA+ around my house but close to work I have LTE. No problem with switching or losing data connection when I go from HSPA to LTE. Just double check your APN settings. There might be a typo or some missing field. Or you can create a new APN for lte and use that as your default.

[Q] XT1045 won't connect to LTE

I picked up an XT1045 (Moto G LTE USA) recently from Amazon and had T-Mobile ship me a new micro-SIM, then called them to activate it. I know there are LTE towers around (had customer support tell me as much) but I never see "LTE" in the status bar, always "H" or "H+". Granted, download speeds in San Jose on HSPA+ are pretty fast, but I am wondering if I'm missing something fairly obvious. I have the default LTE APN selected.
I did unlock the phone using the Motorola site and rooted it. Could this interfere with LTE operation somehow ?

Which APN are you using. You should be on fast.tmobile.com

I have the similar setup (xt1045,unlocked bootloader, rooter, stock 4.4.3 and stock kernel) and don't have any issues. It did take a few hours after first boot. I am in a refarmed area however. Mine defaulted to the lte/fast apn.
a few things:
- tmobo indoors isn't great in all places, so try outside
- if you're on wifi, they downgrade to hspa/3g to save battery, you may not see lte until you get off wifi
- you may be over your monthly 4g cap
to be honest, their hspa+ speeds are same as lte out here anyways

barrmulio said:

Even if you are over your monthly cap, you still connect to LTE. It just lowers your speeds.

Thanks all for the info. I'm using the T-Mobile APN that came with the phone (fast.t-mobile.com), wifi off, have tried indoors/outdoors.
I'm pretty sure I'm not over my data cap -- my previous phone was a Nexus S and my data usage habits haven't really changed yet
It is a much snappier phone and the HSPA+ and wifi and GPS really are much nicer. I like having the microSD slot too. So I can't really complain too much.

Never saw 'Phone information' come up. I'm assuming this would be the same as changing 'bearer' in the APN setting to 'LTE' instead of unspecified (tried that already, it just seems to get no data at all then) ?

So when you dial *#*#4636*#*# , what is the first menu on the top?
It's not the same, cos if you set it there, it allows of 3G connections if no LTE available (dunno if you force it from Settings -> More.. -> Mobile Networks -> Network Mode -> LTE ).
The Airoplane mode is just to "relog" to the carrier network , you just cycle through it On->Off

The correct combination is *#*#4636#*#* and you dont have to press dial after that, the menu should pop-up right after you press the last character.This is not model specific either, it works on all android versions/roms.

Apparently doesn't work on this phone. It's ok, google led me to a couple of apps which appear to do something similar. Thanks for the insight !

Finally got the "LTE" indicator while outside eating lunch near work today. I was amazed that the speedtest.net app reported ~30Mbps down / 20 up. Didn't have to mess with the default T-mobile LTE APN. I guess T-mobile's coverage is just kind of spotty, but maybe the nearby tower was just upgraded or something like that
