[Q] no 4g or lte on stock or custom rom

So I've had this phone for almost a week now and I used to he able to get 4g LTE. But ever since I rooted it, I no longer get more than 3g. I now have bananacakes Holiraider 1.6 but I still don't get any higher than 3g. So my question is how do I get 4g and 4g lte. Oh and if anyone is using that custom Rom, is it possible to get faster than 1512? In his thread it shows you can clock it to 1566. Thanks a bunch I'm kinda new to this!

try dialing *#*#4636#*#* and see what your modem is set to, it should be GSM/WCDMA/LTE auto
you also may have an APN issue, verifiy that your APN is correct, perhaps contact your carrier for the correct APN settings for you phone and plan.

Well I'm now running a custom ROM. The apn is the same as other users and it does say the above. And yes I am in a 4G LTE area

Try doing the above and change to LTE only.
Then once you have 4G change it back. It should stay on 4G. I had to do this to get 4G on official rom.

Ok I just tried that but it wouldn't let me to switch it to LTE only. When I did, it switched it back to GSM/WCDMA/LTE auto. I'm just gonna relock my phone and set it back to the original stock rom and format my phone (yes I have the apps and stuff backed up). Because my actual mobile connection fluctuates on and off as well

the phone should be locked into the GSM/WCDMA/LTE setting. If you try to change it from that setting it just returns back. The phone will get instructions from the carrier's base station to tell it whether to be on LTE or just 4G/3G. Using *#*#4636#*#* under phone information, what is listed as the Network type?

It is locked in GSM/WCDM/LTE auto.

above that option it should tell you the network type. it is about half way between the "run ping test" button and the "Set Preferred Network type" option. Need to know what it says there.

Oh ok I see what you mean, it says HSDPA

make sure that you are in a active LTE area. toggle the radio off and on. the network type should change to LTE if it is available. remember that if you make a phone call your phone will drop back to just 4g/3g and it might take a second for it to switch back to LTE.

I live in Los Angeles so I'm like in the center of the LTE center in Southern California. But for some reason my phone won't get anything higher than 3G, and my actual cellphone reception toggles on and off randomly too.

It worked before. For the first 3 days atleast. And now all of the sudden it wouldn't work, so I rooted it and installed a custom ROM

Try one of WildChilds custom ROMS. LTE works on both and they're tailored to US users.

if the problem arised before you rooted and rom'd the phone I doubt the rom is the problem. there is always the chance that you have a bad radio.

That's what I'm thinking... What would I do about this?

i would verify your sim with another 4gLTE phone and vice versa.

Hrm... So it could be a Sim card problem eh? Unfortunately there are no other LTE devices for me to get a hold of... Would this be the only way?

it could be. i hope you have pulled battery/sim and then rebooted already. you can verify your phone with a known good sim and verify your sim with a known good phone. I would try your local at&t store. they might be able to help.

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution
I recently got my XT894, Droid 4 in the mail, and hooked it up to Rogers Wireless in Canada.
When I was receiving phone calls, the built in dialer would tell me that "Pay Phone" is calling, the solution to contact the Rogers Customer Care, and have them remove the "Name Display" option.
Rogers has 2 services for call display:
Name Display (which does a phonebook lookup from Roger's Side)
Call Display (the number of the dialer who is trying to dial you)
Most motorola radios don't actually support these 2 features together, so Blur reads it as "Pay Phone". After contacting Customer Service, have them remove ONLY "Name Display". I restarted my phone then everything started working properly again.
I hope this helps someone!

First off, I wanted to say that I'm on the leak 6.16.206
I also got mobile hotspot working on Rogers (this solution may apply to other rooted users running on different providers).
I added the APN settings as defined originally here: http://forum.xda-developers.com/showpost.php?p=20366961&postcount=2
Name: Rogers Tethering
APN: isp.apn
MCC: 302
MNC: 720
APN type: dun
otherwise, any other fields are showing as <not set> OR None
When I tried to add dun to the apn type, the moto UI told me only providers could add DUN types, so I went into SQLite Editor -> Phone/Messaging Storage -> telephony.db -> carriers -> Located the last APN which I added manually, scrolled over to "type" then long pressed that field, chose "edit field" and added dun. Once completed, I restarted my phone. I now have the stock mobile hotspot app working (I had to also disable the entitlement check earlier) on Rogers!

Now wait, you got a Droid 4 working on Rogers????

Yup, no LTE though, just GSM HSPA
Sent from my XT894 running ICS

I can confirm that the Droid 4 works on Rogers. Took a week of fiddling, but it works.
Received the Droid 4 with 2.3.4 installed. Did the over-the-air updates to 4.0.4. Rooted it, installed SafeStrap 3, and installed Olegfusion's CM10/JB ROM (4.1.2), and was off to the races. Shows "E", "3G", and "H" when accessing the Internet.

have you ever try with stock kernel?
I wonder not to update to CM10 right now. I have a problem, it seems to connect, 3G/H letter, bu no tranmition. I have an old jaj, Droid3 working perfectly with same APN records.
Any thing that could help me??

LTE on this phone is not compatible with the Rogers network. If you want a Rogers LTE phone, pickup the Motorola RAZR HD. The phone will operate on 3G or 3.5G, although we in Canada consider HSPA+ to be "4G".
LTE can give you rates of up to 100mbps usually gives you about 25-30mbps
HSPA+ can give you rates up to 12-15mbps I usually get 4-5mbps
I hope that helps!

how hard is it to get Droid 4 to work with Canada (Rogers)?
Do u have to have unlock it and then update to ICS, and then you're all set?

The phone comes unlocked, you just have to load up ICS and throw on the Rogers APN (rogers-core-appl1.apn) and you're good. If you want to do some of the advanced features like setting up wireless tethering and stuff along those lines, you'll need root.

so you're saying that all droid 4 are already unlocked?

Yes. They are still blocked against US GSM carriers but will work fine everywhere else, no locks.

Maybe someone can help me, I'm on Rogers. I have this same issue on Stock ICS .217 and on CM10. I can make phone calls and send text messages, but I cannot receive either. When I put my sim card in to another phone, I start getting my text messages. Any ideas on how to remedy this?

Have you tried another SIM card in your phone? Sounds like you have something wired. I would also check to make sure you are in global mode on the phone.

eBay, yes.I got mine as "bad ESN" from a liquidator, it was quite a good deal. Obviously, by now you can find clean ESN versions for below $250.
Anyways, I am on Koodo/Telus. Under Mobile Networks Settings / Network Mode set GSM/UMTS and Select Network must be UTMS only, the default finds GSM which is weird because Telus AFAIK does not even have a GSM network! It has CDMA, HSPA+, LTE even iDEN but not GSM. Before I forced UMTS, phone calls worked more or less but mobile data rarely. Since I forced UMTS I get mobile data everywhere, inside buildings, all that -- I had lots of reception problems with Wind Mobile, Telus is infinitely better.

I went through the process today and got my stock Verizon 217 Droid 4 working on Telus. I verified the Telus APN settings, went through forcing GSM/UMTS and UMTS-only mode, but still have terrible reception: 1-2 bars, -100dbM. Any thoughts for getting better signal?

[SOLVED] DROID 4 Canada SMS/voice only, no data on Rogers/Fido - help!
SOLVED! see below.
Droid 4 from Ebay, $135 or something + shipping. Replacing my string of bad luck with i927's from smartphone_wholesale (aka Cell Phone Forever) on ebay (tho the 1st one they sent was great til i lost it).
SMS/Voice is fine but cannot do any cell data on it. Following all settings on fido's site for APNs the fido-core-appl1.apn doesnt work. Had to manually put it in (APN list was blank). Tried my wife's Roger's sim, it populated the APN list itself (4 of them, all combos of internet w or w/o MMS, and rogers +/- 'internet' in the name). None of them work either (they match what's in the fora here and on the rogers site, rogers-core-appl1.apn etc).
Im a bit of a newb: is my phone not unlocked properly or something? What gives? Radio is set to global or GSM/UMTS (CDMA doenst work of course). What's the solution here?

yes mobile data is on (and roaming set to yes but phone states it's not roaming now)
every time i've added apn's and saved i've rebooted (and rebooted twice with wife's SIM in too, in case settings had to go sim -> phone + reboot, etc). No luck any way ive tried.
Thanks for help.
[UPDATE]
belay that request cadet!
Ok I just removed the wife's sim and put mine in, rebooted, and this sim (fido) doesnt populate the APN list. I was in the middle of inputting settings for it, hadn't finished and a buncha text+ came in and wifi is off (I saw I was on Edge, big blue E on status bar). Then before I could even react I had hit save, and data turned off.
Yep, removing "internet" from the APN 'type' works fine. Leave it blank.
W t f. Maybe someone can explain that shiz to me.

[Q] Droid 3, no 3g after 2.3.4 update (maybe)

Yep, another noob with a busted phone. Verizon Droid 3, about 5 months old.
I've just noticed that I have no 3G. Not a 3G problem, I've confirmed with another phone that I'm in a covered area. Normally I'm under one Wi-Fi net or another, so I rarely use it. Noticed it yesterday when I needed it.
Allowed the 2.3.4 upgrade back in May. No problems, just had to reroot the phone. Pretty sure this started after the upgrade, but not 100% sure.
I've tried Googling, saw the *228, tried it, nothing. Found threads about task killers causing issues, uninstalled Advanced Task Killer, nothing. Pulled the battery and rebooted, nothing. Saw some thread on APN settings, but those are not available to me with Netwrok Mode set to Global. I can set it to CDMA, still has APN setting greyed out.
Not finding anything else much to go on, could use some help.

One thing you could try is hitting *#*#4636#*#* then Phone Information and changing the network to EVDO only. That would force it to connect to 3g. Then if that doesn't work try manually forcing a PRL using ##Program. You could always call Verizon.

Are you on any rom? Stock?
If your on stock, I would go to verizon and ask for a replacement or see if they can give you a replacement or fix it.
If your rooted/custom rom I would try re-downloading whatever rom your using and reflash it. And wipe caches.

I've actually had a few issues with the 3G on my own D3. These steps generally work for me.
Navigate to your APN settings. Settings>Wireless & Networks>Mobile Networks
Press Menu (An option should pop up that says "Reset APN" or "Reset Values")
Press this and wait a few seconds.
Reboot, and you SHOULD be up and running.
If this doesn't work you can edit the greyed out APNs manually (NOT advised) with a trick I can show you. Hope I was able to help!

Thanks for the suggestions so far. Unfortunately, none of them have worked. EndAllFUD, even switching over to GSM so I can get to the AFN settings, there is no reset that I could find.
I've went back and tried unfreezing all the oddball authenticators under the assumption that maybe one of then was IDing me to the 3G network. That hasn't worked either. Unless I come up with another idea, I guess I'm going to have to try Verizon and see if they can/will help.

Well, we have a resolution. After everything up to and including a factory reset, it seems that the 3G radio in my Droid has died. Verizon is sending me another; I'm springing for the overnight shipping.
I had forgotten how much effort had went into customizing this thing. The stock phone is just...painful.
I appreciate all the help that was offered.

Sorry to hear about the 3g radio in your D3, but glad to hear you resolved your issue! Also, I was going to amend my solution. I was basing my answer of memory due to the fact that I am currently running Hashcode's CM9. (It's amazing by the way) The proper instructions were as follows: (Amended instructions are in bold.)
Navigate to your APN settings. Settings>Wireless & Networks>Mobile Networks
Set network mode to GSM
Change mode back to Global but quickly start tapping the "Access Point Names" menu until it lets you in.
-(You are now in the locked Global Settings Menu)
Press Menu (An option should pop up that says "Reset to default")
Press this and wait a few seconds.
Reboot, and you SHOULD be up and running.

Yeah I just had to throw in a trick I figured out one day when I was screwing around with my phone. My apologies for not remembering to put it in earlier.

Does anyone know how to tweak Droid 3 to make it able to call, message and 3G, but not 1x data?

It isn't possible to make calls or texts using CDMA service locked into EVDO only. If you use Google Voice and a SIP program it would work.

I'm on my 2nd HTC one and it operates the same as my 1st one.. In the dock of my car it connects to 4G just fine..with in a few seconds of handling the phone it drops to 3G..It works fine in great signal areas but on the out skirts of an LTE tower it just won't hold 4G..

Im in the same boat. Seems like 4g is HORRIBLE with this phone. Had the Note 2 and wife has GS4 both pick up 4g no problem, but the One picks up 4g for couple seconds then drops off completely. Yes, I tested this in the same areas.
really bummed out cuz I got the phone used so i can't return it. Love the phone, but its useless if i can't get 4g because Sprint's 3g is so slow its unusable.

Well I just exchanged my black and went back to silver and still the same issue. I am starting to think the guy that set up my phone on my account jacked something up. I have been all through the service provisioning matching it to my friend that has one....and only found one difference. Seems my phone is only picking up CDMA-EVDO Rev-a instead of CDMA - eHRPD. When I change the prefered network from LTE/CDMA it will try to connect to eHRPD but then switches back to EVDO and no 4G. So I will try to call sprint and have them inspect my account as I have not seen a way in the service programming to force eHRPD. It would be nice to have the others that are having this issue check the Mobile network type as well and see what they are running.

Try not touching the phone and see that it holds 4G until you touch it...I know its pretty useless to not be able to touch your phone but this has been my experience.

In my experience, not touching the phone does not seem to fix the problem. I do notice a small signal loss if I have the left side of the phone against the palm of my hand. The real issue here seems to be related to the phone having some sort of broken threshold from when to switch to 3g to 4g and how much better the 3g signal has to be in order to decide to switch off of 4g to 3g.
I noticed that the LTE Scan Time is set way higher than what the EVO LTE is set to with latest firmware (300 on the HTC One vs 5 on the EVO LTE). I have not had much time to test changing this to see if it makes a real difference or not though. You can check what your LTE scan time is set to in ##3282#. You will need to get your MSL to change it if you want to do that (there is a method to get your MSL without rooting here on XDA).
Another thing you can try to see if it is indeed a reception problem or a problem with the phone not switching between 3G and 4G smartly is to set the phone to LTE / CDMA(1xRTT) only. You can do this in *#*#4636#*#* under the phone information submenu. Tap where it says "CDMA + LTE/EvDo auto" and change it to "LTE, CDMA" or even "LTE only".

Issue resolved for me! After 6 phone exchanges I was able to uncover what was causing the phone to not get on eHRPD which is Sprints upgraded software on the towers. I called sprint support and made them verify my UICC ID under about/phone identity, this also is the same as number as the SIM id. They did not match what was on my account. I went back to Best Buy and they called activation's and they sent a profile update with the correct SIM and UICC ID and it solved the issue. No more 104 data issues and I can get 4G now. WOO HOO!
I do want to say that Sprint really went to bat for me to get this resolved. I have to say thanks to the San Diego Sprint rep who kept in touch with me through out all of this.....Thank you man!!!

You have to call sprint customer care to have them verify what you have on your phone. I recommend calling from some other phone when you call though. Just explain that you are having issues with your data and you heard that sometimes the UUIC ID/SIM ID are incorrect. They might come back and tell you, "well thats for international only" but in fact the SIM ID is used for LTE from what I found out. Just insist (nicely) that you just want to try it.
On the phone you can see your SIM ID under settings/about/Phone Identity.
One way to see if this fixes the issue is look under settings/about/Network and look under Mobil Network Type. If it is always running in EvDo rev A. then you have the issue if the towers in your area have Network Vision updated towers.
Hope this helps...PM me if you want more information. I can also get you tower data in your area if you would like.

slayer69, Thank you so much for your quick response. My phone runs with EHRPD when it showed 3G, not rev. A. However, my phone had the same issue, not connecting to 4G/LTE. From time to time, it will show 4G signal on the bar. However, when I tried to use it, it will switch back to 3G. I will call sprint to verify if tI have the sim card issue.

I talked with Sprint. It seemed that my SIM/UICC code is matched with the system. So my problem is still not resolved. I used an app to check the signal information, which showed that I have -70dB LTE signal. However, I just can't connect to LTE.
It seems that it is not only me. Check this link

Thanks to all in this thread. I had the same problem while in Oakland. My wife has an S2 on sprint and she had a strong 4g connection and mine was stuck on 3g. Now if this is a hardware issue that this phone has what if anything can we do. Can we exchange for a different device

No LTE?

I apologize in advance if this has been addressed before. I'm running stock-rooted 5.0, stock kernel, and what I think(?) might be the radio for 5.0.1 I'm not sure... APN settings are correct and in the *#*#4636#*#* Phone Info menu I'm using LTE/GSM/CDMA Auto (PRL). Do I need to double check my radio or do something else? I'm on T-Mo with the TRULY Unlimited data plan. Any suggestions?

Are you sure there is no LTE. I believe come of the notification icons are finicky. In other words, on mine someone it will show extremly low service bars but does not affect my phone? or data in any noticable way. Also are you in a bad service area?

What does the top right say? Have you received lte on previous devices being in the same location where you are now?

Radio for 5.0.1 ends with .04R. Do you ever show LTE in settings, see my screenshot. I've got Verizon obviously but with TMo you should get LTE too. If you have another phone stick the sim card in it and see if you get LTE in the other phone. If not could be the sim. Could be bad signal area too. FWIW TMo LTE is band 4 and soon to come band 12.

Wow. Thanks all for responses. @vvveith I am in an excellent service area LTE for miles! @zephiK Yes I used data over LTE on my Nexus 5 just fine. @jawmail Yes my radio ends with .04R. Sadly I do not have another phone nor SIM card adaptor to try your method with. Would the newer radio make my data signal fluctuate b/w 3G, H, and LTE? I understand that this is a different phone but I swapped radios on the Nexus4/5 all the time and it never hurt anything.

1) Did you get LTE on the 5.0 Radio?
2) Try setting it to LTE/GSM auto (PRL) instead
3) When you say APN is correct. Which one are you using / looking for? Ensure it is T-Mobile 4G LTE IPv6 (if its already on IPv6 try IPv4)
If worst comes to worst, go to the T-Mobile store and get a free SIM card replacement, if they don't want to give you a free SIM. Give them a call, it'll take a couple days to arrive but T-Mo employees are quite nice about giving SIM cards. Especially since you paid for a N6 which is expensive.

1.)Yes i did and it was much more reliable.
2.)Overnight I switched b/w those two settings and kept getting the same result.
3.)I switched the APN to IPV4/6 and that seemed(?) to have solved it.
This has been going on for a couple days so I might see if I can get a new SIM.

I cannot find where set the APN don't see under More, Cellular. I can VZW where can I find the APN on N6?

You had it right, its under more > cellular > access point names (APN), then select your carrier.

For the rom I am on I don't see under cellular the option for APN. Do I have to be back to factory to see it.
