After weeks of playing around with build.props, APNs, and patches, on custom ROMs and stock, I am still attempting to get faster and more consistent data.
4G and LTE are supposed to be possible, but I can't figure it out.
I can get around 5 Mbps down using WCDMA only, but the very next moment in the same spot could be something entirely different.
My mobile data goes out quite often where it is just the outline of a triangle. I have never seen any other letters besides an E and a H.
I am currently on stable CM 10.2.1 installed on a newly created and wiped SS Slot 1, and have been for about a week and a half.
I used default network = 0 in build.prop this time around.
I finally managed to get my phone to recognize my SIM card while using the following configuration:
default network in Phone Testing = LTE/GSM/CDMA auto (PRL) and
preferred network mode in Mobile Network Settings = Global (CDMA/EVDO/LTE/GSM/WCDMA).
It acted really strange at first but the settings stayed even after a handful of reboots.
I am using Straight Talk's current APN settings (tfdata).
My dBm is constantly going from about -90 something to -108 and my asu ranges from around 3 to 14.
Before I just now rebooted, and every so often, it shows 2147483647 dBm and 255 asu; I have only just noticed this in the past few days, however. It is now back to -101 dBm and 6 asu after restarting.
I have attached screenshots of it doing that and a shot of "normalcy", as well as my last few speed tests.
Can anyone tell me what I might be doing wrong?
Should I try default network = 10 again in build.prop?
Or could anyone provide a copy of a build.prop working on all possible network modes (with the ability to edit APNs)?
Thanks in advance. I will take any and all advice or opinions.
I am so over trying to figure this out! When I really need my mobile data, it doesn't work!
I have attached a couple of graphs of my signal highs/lows etc. These results are from the Real Signal app.
I don't really know what they mean, but I am hoping they might shed some light on my issue and I'll get an answer from someone.

How are you getting it to get edge data? On mine I either have HSPA or nothing. Is there a way to make it default automatically to edge when the HSPA signal gets weak. I tried using liquid smooth 4.2.2 and changed it to 2g only and never could get signal. Change it to auto and get HSPA again

Not really sure how, and when it is on Edge, data hardly works anyway, so I probably can't help you there.
But I do have default network = 10. Only other thing I changed was telephony.lteOnCdmaDevice=0 to get the APN menu under mobile networks.
However, at the moment (and the majority of moments), with Wi-fi off, I have no data, -109 dBm, 5 asu, GPRS service is disconnected, and my phone number is "unknown", so I am definitely not in the position for giving suggestions.
Am going to try CM 11 again today, but I was hoping for some answers before doing anything other than installing..
I will ask more specific questions in the hopes that someone, anyone, can provide some sort of idea for at least 1 of them..
Is it even possible for the Bionic to have consistent, non-frustrating access to 2G, 3G, 4G, and LTE when unlocked for the AT&T or T-Mobile networks using Straight Talk?
Is there a way to enable the APN menu without changing the build.prop?
Does anyone have a targa build.prop (entire thing or line changes) of phone that has reliable data, etc. working on 2G, 3G, 4G, and LTE?
Could it be an issue with the SIM card itself?
Am I even approaching this from the right angle?
Should I just give up and get a new phone?
Thanks in advance.
Patch Idea
I am a novice at best and that may be a stretch.
BUT. Both of my Bionics are running on Straight Talk AT&T 4G sim cards.
One is a hardware REV-B the other is hardware REV-C.
The REV-C is rooted and running on the Jelly Bean stock rom.
The REV-B is rooted and running on a MoKee MK4.4 KitKat Release that I downloaded
from their site and opened in "Safestrap".
I do not think that I have achieved 4G yet however,
I do have fairly stable signal and data since
I installed a CDMA to GSM patch that I found searching these forums.
It includes Straight Talk and AT&T APN!
I am not aloud to post links yet. But if you search for these things here you will probably find them fairly quickly.
I would love to know if you can achieve 4G!
Good Luck!

Was just messing around with my Nexus One, I have used the *#*#4636#*#* trick to turn on GSM Auto (PRL) Which greatly improved battery life but didn't do much for signal so just now I was messing around went back into the phone info section turned on GSM Auto (PRL) then went down to OEM-Specific Info/Settings and turned off ciphering and wow my dbm went from -101 down to -87 and I seem to be able to hold a 3g signal reliably. If I grasp the phone tightly and intentionaly try to make it lose 3g I still can but holding the phone normally it seems to stay on 3g and doesn't fluctuate nearly as much as before.
Can anyone else give this a try and let me know if it's just a fluke? Never seen my DBM's so low before in front of my computer so seems like something is up here.
I don't see any difference, but I am on 2G right now.
Meh, don't read it if you don't like. It is the first ever thing i've tried that actually noticeably improved my 3g reception so thought i'd share it. If enough people notice simliar increases in 3g reception perhaps it will lead to an official fix from Google. If everyone remains quiet on the subject we will never get anywhere.
Cheers

It doesn't search as much when on wcdma. GSM auto(prl) is basically a file that contains a lists of towers in your area that you have access to. So your phone uses that instead of searching all the time.
Here is some more info
http://en.wikipedia.org/wiki/Preferred_Roaming_List
and I'm sure there is others.
thanks for the tip. I tired it and my dbm went from -102 to -87 to -93 range.
does having a lower dbm means better signal? I have a place where my 3gs gets 2-3 bars, and my nexus has 0 bars. Kind of disappointing, the the cell radio in the nexus 1 is not as strrong as the iphone 3gs. I'll test the phone later there, and let you know.
Yea, lower the dbm the better the signal, it definitely helps but doesn't alleviate the problem with holding the phone from the bottom. I have since switched to WCDMA Only to help combat that problem. It seems I am able to stay on 3g pretty reliably this way even though I sometimes lose all bars when holding the phone from the bottom it still stays connected to 3g and I am able to surf the web and make calls with no bars showing, it's rather peculiar but it's working for now so I won't complain. If this doesn't work out I think I will end up switching to Sprint and going with the EVO on June 4.
Definitely that's one thing I noticed is with zero bars my phone still makes clear calls and fast data, so I just figure the signal meter is just more conservative than other phones.

So what exactly does turning off ciphering do? Is it worth it for the signal boost?
Ciphering is to keep other people from hearing your conversations, it's like encryption...not a big deal for me as I've nothing to hide and never give out credit card numbers over the phone or anything like that but it might be an issue for some.

I am assuming that Ciphering is purely the encryption aspect ...
So it gives me the options now, instead of global or cdma, of cdma, EvDo, or both. So myquestion is, what are they and what should I use. All of a sudden, after a couple days, I was having massive data loss and huge battery consumption when I switched over to both. But now I use evdo only, but what does each do, like, what should I have enabled to go back to the battery levels I was having before. Now I have 3g, but terrible battery life, before I had both. Help please!
P.S. sorry for not posting this in the dev section, I don't have enough post.
Sent from my DROID3 using XDA App
global should be GSM + CDMA. CDMA RTT is 1x (slow) and EvDO is 3G. Im not sure about the GSM portion of CM7, as I know there may be a patch or another version of CM7 for GSM. my D3 is running CM7 with CMDA + EvDO chosen and my battery is fine.
Okay. Thanks for the response. I don't know what was going on, it was getting hot, and my data was dropping. I'm going to let it charge back up, then leave it be. See how evdo+cdma works for a while. Thanks again!
Sent from my DROID3 using XDA App
also, if youre using safestrap, make sure youre running 1.06 (or higher if applicable)
I think I may have found the culprit. My display has always been first. Now all of a sudden, bad battery life, and high android OS numbers, anyone else smell something fishy?
Sent from my CM7 Droid 3
my advice is to make sure youre using 1.06 SS, and format /system, install CM7 11-16, wipe data/cache, and boot that beast up. my display is highest, android OS is at 13%. My battery is at 56% and ive flashed 3 times today since taking it off the charger at 630am
Im on the bootstrap from the market. I switched back to sd3, I gave up with it. But have either of you used both cm7 and sd3? Which did you find better for battery life? Also, SHOULD I BE USING EVDO+cdma or cdma only or evdo only. UGGGHHHH
Sent from my DROID3 using XDA App
probably use both cdma and edvo. ive used both SD3 and CM7 and Monster and DD and Liberty and Mavrom. And I flashed CM9 once lol. Ive had the best results with Monster previously, but now its CM7 as a clear winner in my book. the bootstrap from the market is missing several options. i would suggest reading up in the dev section, under safestrap. be careful or you'll have to sbf, but once in place, safestrap is the king of recovery
This is just getting weird now. I left it on cdma only, but disabled wifi over mobile network, and it went 3g. Then today, without touching any settings, it went to 1x bars and even toggling it wouldn't change it. But evdo is only 3g, no 1x bars. But both is 3g. I'm getting really confused now. Its like its only 3g when it wants to be on cdma.
Sent from my DROID3
I think everyone is confused on a few things. Lemme see if I can explain it a bit. CM7 doesn't have the same option in Wireless and Networks, so you push *#*#4636#*#* and choose Phone Info. Under there you can change the networks between GSM and CDMA types. GSM/CDMA means it searches for GSM signals off the SIM card and searches for CDMA signals as well. CDMA is the same as 1x and EVDO is the CDMA version of 3G. If you set it to EVDO only then it won't go to 1X unless you make a phone call and you won't receive any inbound calls or texts. This can be handy if you want a solid 3G connection without interruption from a text or phone call. 1x only is no 3G and if you get 3G it is a fluke. CDMA auto (PRL) is a combo of 3G(EVDO) and 1X which is normal Verizon usage.
Generally you want CDMA Auto because it disables any GSM signal and give you better battery life (disables GSM radio and uses less power). 1x or EVDO only are part of Verizon service but not standard.
I hope this makes sense and if I make a mistake please correct me. I didn't sleep well last night but I hope I clarified a few things.
If you are getting 3G when you set it to CDMA only then you need to report it to Hash as that is a bug.

Can somebody be so kind and upload stock buid.prop for Bell AHD?
Wanna see differences between the AT&T and Bell setup - looking for way to enable network type switch in phone info
Thanks
here you go!
please extract it to get the build.prop for a bell AHD
Well, I tried replacing build.prop in hope that will enable band switch but it did not
I would really like to have option enabled in settings or trough phone info.
In phone info i can switch between LTE/GSM/WCDMA and LTE/CDMA/EvDO/GSM/WCDMA.
Any other choice reverts back to LTE/GSM/WCDMA. I have done EB40 battery mod and I am not worried about battery life as I can pull out 2.5 days on medium usage but 70% of my day I do not need LTE so I was hoping to extend battery life even more by switching to EDGE

I dont know what ATT did...
I followed instructions from here: http://forum.xda-developers.com/showthread.php?t=1386383 and I got network switch enabled in settings but when I select GSM only setting does not stick...Reverts back to LTE.
I tried adding ATT 3g APN (wap.cingular) but it wont connect to the data network at all???
Really stuck now.
Generaly I always used 2g data connection when I am at work as I still can get my emails and mms and do some basic browsing and internet radio streaming. Then if I stream videos or download apps or upload large amount of pics I would switch to 3g (LTE in this case)
I wonder does it have anything to do with account provisoning for LTE???
I really would like to have that option enabled and working. I know ATT is in the process of phasing out 2G data on account of LTE but as long as it is available I would like to use it...
After completing the steps in that post and deleting the backups change the operator to maritime. Successfully dropped down to 2G /EDGE. Thanks for this thread. Was hoping someone would post a bit of information on it. Here's some screenshots.

Maritime is another AT&T network. It was actually the default on my Atrix 4G. Sadly, the Atrix HD doesn't display the code for each maritime network. Shouldn't be to hard to switch the default to it if we knew which code it was. Setting the default to Maritime wouldn't help considering there's 3.
Sent from my Motorola Atrix HD MAXX
Very interesting. If set to 3G only on Maritime it displays the 4G without LTE. Through Phone Info, it shows that I'm connected through HSPA as well. Selecting Automatic sticks with HSPA unless I get better LTE service. Seems like 3G is a good balance between speed and battery life.

Is there any proof that disabling LTE saves battery life? In older phones, disabling 3G would save battery life because there were separate chip-sets for 2G and 3G services. That isn't the case now, a single chipset handles all signaling. Thus, there are no chips that are powered down when 4G is disabled. I would expect battery savings to be minimal.
Additionally, because of the increase efficiency of the LTE network (combined with less network loading), your phone will have an open data connection for a much shorter time, when transmitting data.
I've got my AHD on the AT&T network using a StraightTalk AT&T sim. $45.00 unlimited everything. With the APN that straight talk uses, it never searches for LTE. Just on 4g all day long, with no LTE searching at all.

Hello guys,
So I just bought my HTC one about a week ago. I'm.. pretty much in love with it. I haven't had time to sit down and room and customize it and such, but plan to soon.
However, i'm having an issue with it. The phone shows that it is connected to 4G and has full signal. However, it will not load anything whatsoever. Sometimes it works... but most of the time it does not, and I cannot figure out why. I also really hate that I can't manually toggle JUST the 4G on/off without diving into the settings. Waiting for the phone to decide to search for a 4G signal is frustrating. I'm somewhere I know has 4G signal, but the phone takes a long time before it realizes.
Is there anyone else who has these issues or someone who knows what I can do about them?
Thanks

I've actually been having that issue for a week or so. No matter what ROM I'm running. Very strange. Maybe Sprint is "upgrading" their towers....lol. I'm in VA, are you in VA by chance?

Maybe someone can answer this better but 4G doesn't have "bars" the bars are for your 3G do you may show full bars but still have a weak 4G signal.
The best way I have found to address this is if your connected to 4G and you aren't able to connect to anything go into your mobile data settings and temporarily switch to CDMA only, or toggle CDMA then switch back to CDMA/LTE this will cause your signal to cycle and you may be able to browse using the 4G.

Datdude, no i am in Texas.
Konfuzion, thats disappointing. Toggling the signals through the settings is really clunky and always ends up with my phone having no signal at all for a couple minutes while it cycles everything. Is there an easier way? Maybe a widget I can get somewhere to do it more quickly?
Also, I dislike that I have no representation of how strong a 4g signal I have. I don't want the phone to tell me I have signal where there is none. Is there a ROM that will show this, maybe?
All in all, while I love the phone, I'm beginning to regret the upgrade. 4g data is very important to me as I use my phone as a mobile modem for work. In places (the exact same chairs) where I had strong enough WiMax 4g signal to do what I wanted, even to play latency restricted games like a MOBA, I can't get the LTE to do anything. I really don't want to have to downgrade, just to keep access to an inferior 4g signal, even if it's more reliable.
Bump for help?
Check out SignalCheck Pro, it will show you your true 1x, 3g and LTE signal strength. I just got my One on Monday and haven't had any 4g issues here in NC.

You can also check your LTE reception by going to Settings->About->Network. Anything above -120dBm RSRP is useable, though if it gets much lower than that, the signal becomes tenuous. I think the lowest I've held onto was -124dBm.
Also, I run into this problem every few days around Chicago. The data connection just seems to stall. The fastest way I found to fix it is to toggle Airplane mode with the widget that I keep on my home screen.

Thanks guys for your responses! I went ahead and bout Signal Check Pro and although I don't understand all the numbers, my RSRP is around -105 to -110 at the moment, so it looks like i'm on the lower end of the connectively spectrum. Hopefully this app will help me better understand when my 4G is and isn't going to work.
Hey guys
So I looked around the forum for an answer to this question and i found similar topics but not exactly what I was looking for. I have the HTC one with sprint and the only issue I have with it is how it handles its preferred networks. If have 2 bars of LTE but 4-5 bars of 3g its going to stay on 3g and not switch to LTE. Is there anyway to change how it gives each signal preference. Currently it will wait till there is no 3g signal before it switches to 2g but LTE is not giving the same preference. I know it's just this phone because I had the iphone 5 before this and when I was on campus at my university it would stick to the 1 bar of LTE i had rather than switching to 3g. If I force the phone in LTE only mode then it will pick the LTE signal but then I can't call and text obviously so it's not very useful.
There are two things that the iphone 5 did which I miss but otherwise love this phone. One is getting LTE in places that has low coverage and the other is roaming on verizon network on 3g. The iphone would always roam on 3g but the htc one only roams on 2g.
Is there a way to change those things with this phone? Thanks in advance!

Have you tried changing the preferred in the *#*#4636*#*# > Phone Information?
Hi thanks for the response. Yes I have messed around with that. That's how I got the LTE only option. It isn't a matter of not finding LTE signal. It's just the way the phone handles what is perferred. The phone first sees if there is a strong LTE signal and it catches that but the moment it goes to about 3 bars or less it will switch to 3g. I want it to continue sticking with LTE until the signal is gone completely like it does with 3g -> 2g.

I know it's not an optimal solution, but have you considered using Google Voice integration in the meantime? With LTE only mode, so long as you're signed into an app of choice (Google Voice/Hangouts should be able to handle your calls and texts if you tweak at it a bit), you should have the desired service until you can get some dev help.
