Losing 3G Mobile Network on certain location

Hi Experts out there,
I have been having 3G mobile network issue with CM7 base ROM. On certain location, I cannot download and make or receive calls. my 3G icon arrows show upload activities but no download happening. My ISP name (Maxis Malaysia) showing as normal. I upgraded to CM7.2, tried Kang ROM, preshoot kernel and change new SIM card but doesn't help.
Disable and Enable the 2G only a few times might resolve the problem for a while. The may come back again as long as I am still at the same locations.
Anyone has any ideas on this problem? ROM or Kernel issue? Recommendations on solutions? Thank you.

It's not the phone. It's signal coverage that you're having problem. Try another location and see if that helps.

I have been getting full bar signal strength on the icon. If connected (after a few tries of enable / dissable 2G only), the connection will be good for a while (some time quite ok for hour). The connection on 2G is 100% stable and reliable. If 3G is weak, it should automatically switch to 2G without issue right?
Thank you for the reply.

No. The problem could be with internet access of the specific UMTS base station that you're connecting to at that spot, and not with the connectivity between your phone and the tower. In any case, it's not your phone, it's the base station, and there's nothing you can do but complain to your cellular carrier.

I have checked with friends (iPhone, Android, BB,etc) surrounding me on the same location, no one is complaining the same problem. That lead me to confirm that its my N1. The worst part is I cannot make or receive calls. I have been missing many important calls...

When did you have this problem? After or before you updated to the latest version of CM7.2? If after then I suggest you do a full wipe and format system and then reflash the ROM. Or you could try to flash a standalone kernel and see if that helps.

I have been having this problem for many months. Since I rooted my N1 using CM 7.1.

Another option would be to flash a different radio. Try to read the radio section on Nexus One thread for more information

I just flash MIUI ROM and will put it to test tomorrow. Hopefully it will be fine. If not, will try to flash different radio. Thank you for all the replies.

Here's a couple solutions:
1) Go to settings>wireless>mobile networks >access point names. Look and see if an option called "Simple" is ticked. If it is, tick your network name instead of Simple. For example, for me, I have T-Mobile; so I have T-Mo ticked and not Simple.
2) Try flashing a new radio or ROM. I highly doubt this is your problem but it is worth a try. Try the .08 version radio or the .12, whichever you don't have.
3) Go to your carrier's store and see if you can get a replacement SIM card. I did this once and they gave me one for free. Just say you are having connection problems and you think your SIM is cutting out. My N1 once fried a SIM card. Just re-read post and seen that you did this. I would highly suggest you try my first option as I had a very similar problem and solved it that way.

SORRY IM HAPPY CAUSE THIS DOES WORK EVERYTIME DANG T-MOBILE GET AT&T TOWERS btw HAPPY EASTER EVERYONE leave me a egg

I have tried MIUI ROM and latest Radio (5.12) for passed few days. The problem still remain.
The new radio giving more stable 3G connection many locations but lost 3G connection on the previous problematic locations.
Really not sure what to do with it now. I have tried everything that is known on the web.

There's nothing you can do. It's between your phone and local base station.
You didn't listen to me earlier, I guess now you will.

It is sad that nothing can be done. The phone should at least switch to 2G when 3G is not available, but my N1 stuck there causing me loosing voice and SMS capabilities. This is fundamentally wrong on the phone.

[Q] need help for connection problem

hi there, i just bought my galaxy note 1 month ago, and there is a problem with the packet da ta, sometimes i cant connect to the internet and the packet data symbol just suddenly dissapear, i have try to on off my packet data from settings but nothing happens, still cant connect, so i need to restart my phone by turning it off and turning it on so the packet data or internet connection can run smoothly again, please can someone help me with this probelem, is this the provider error or my note?

not sure if it'll help you in any way, as your problem may be completely different, but check your APN settings - few stock ROMs ago, my Note used to change APN name by itself (don't remember now, but sth like "_android" was added to the name from time to time), and I had to manually correct it each time. Then after one of the upgrades the problem disappeared, still don't know what was the reason...

Droid 4 and CM10.2 data issue

Is anyone else that's running CM10.2 on Droid 4 having data connection issues? Have you fixed them? If so, how? Does the code need to bake a while longer before data starts working?
I'm running CM 10.22010831-NIGHTLY-maserati
WIFI is working, but I can't get data to work otherwise. I did a factory reset and started fresh. I've tried flashing the ROM and gapps package multiple times. I wiped cache and Dalvik. I tried repairing permissions.
Any Ideas?
Thanks,
Marty

Tried that and still no love.
I think i need to update my baseband radio, but I can't find a more recent baseband version for the Droid 4.
I'm currently using CDMA_N_05.11.01P LTEDC_U_09.11.00.
Anyone have a link for a newer version or any idea how to get one?
Thanks,

Do u have the issue on stock rom slot? If so then take it back to stock with the latest utility floating around the forum. Check for system updates if there is one dl and install to make sure u have latest radio if problem persist then it's a Good possibility it's A coverage issue or hardware related problem..

Ok, here's where I'm at now.
I updated my stock rom. baseband is now at 5.25.00. Still won't work on CM10.2.
3g will work on my stock ROM, but not on CM.
I've screwed with the mobile network settings and I can't get any difference in results.
LTE works great with CM10.2, but as soon as I'm in 3g territory, I'm dead in the water. I can receive and place voice calls and I get text messages through the messaging app, but anything that requires an actual data connection, like google voice or the browser, it won't work.
Help!?

updated PRL, still no love.

In some versions i needed to add APN manually, then it would work. In earlier version i had the same problem that 3g would not work. Also problem with reception bars - it would always show like 1 bar or smth like this but would work just fine.

It already has several APNs set up. The one I have selected is: APN: vzwinternet, MCC:311, MNC:480. Most everything else isn't set.

Set adrift without data.
Day 10: I've run out of water. The sea gulls... they mock me... with their wings... and beaks... and of course their raucous calls. They are scheming against me. My only friend is the lone shark that circles me constantly. He's attentive like that. A bit forward though. Keeps trying to kiss me. I tell him "NO KISSES FOR YOU! Not until the second date."
Also, still no data.

First off, thanks for the chuckle
Secondly, you're getting no data at all? Are you on Verizon? If so, do you have LTE in your area? My personal experience has been LTE data is working fine but 3G has been REAL spotty. I did see dhacker on twitter post a new razr build with some 3G tweaks he was testing. So that is being worked on and should filter down to us when it does get figured out.

3G was working fine on 10.1, but is nonexistent on 10.2. It actually acts like it wants to connect to a roaming tower if I switch it to GSM, but it can only see it and won't pass traffic.
I could just go back to 10.1 or run stock, but my pigheadedness, that's a word now, won't allow it.
On the brighter side, I am learning a great deal more about my phone that I had previously known.

The problem seemed to rectify itself around the nightly build on 9-15 or 9-16.

I know I'm a bit late, but I always do the * # * # 4636 # * # * in dialer and I turn off the radio, set the radio to cdma/lte and turn it back on, usually it isn't letting all those other antennas run and it seems to pick 4G LTE faster in my experience.

I think it's a CM10.2 issue...
Hi, my friend with a Galaxy S3 is having the exact same data retention issues we are having on our Droid 4's, which makes me think this is a bug in CM10.2 on various devices more than an issue with our phones. I can get LTE data when I have service, but find that once I loose service, even for a moment, the phone then never re-connects to LTE again and just sits there with white bars instead. Toggling data or airplane mode seems to usually trick it into reconnecting to LTE, but it is becoming annoying to have to constantly check and toggle around to get data back. I've tried every nightly and the M1 and have found the issue remains through the 11/19 build. I've installed the ROM into slot1, I'm not sure if overwriting the stock ROM and using the stock slot with CM10.2 helps matters at all, has anyone had any experience with using CM10.2 in the stock slot instead of Sot 1?

[Q] Unable to activate mobile data

Hi community,
I'm a long-time lurker but just until today had the need to join this great place and bother you with a question. I already used the search feature and even googled this problem, which didn't quite helped as I'm still clueless.
Last nite, I switched ROM on my Desire C after being a long time user of Revolution MOD (thanks to @russell664) because sudden reboots started to affect my pone almost daily.
So I went ahead and flashed MiniJBProject (thanks to @penguin449) following the right steps (clean flash), rebooting after install in order to get WiFi enabled and everything seemed to work well until this morning, when I went outside my house and noticed Mobile Data doesn't work. I tried re-flashing ROM, switching between NOPE (thanks to @me4488) and Prometheus (thanks to @nikhil16242) kernels and frequencies to no avail (my pone doesn't go beyond 750 MHz), cleared Dalvik cache, fixed permissions in CWM, nothing.
As I said, WiFi does work just fine but Mobile Data is just not sending/receiving, I'm able to move the slider ON/OFF but get same results.
Then I thought my pone didn't like this specific ROM so I then flashed Revolution JB (thanks to @addictz10) again through clean flash, rebooted to get WiFi, and so on. Nothing. Still the same.
I feel like probably the problem has to do with CM10, since I didn't experience this issues with any of the Revolution Series ROMS.
Any further info you might need to shed some light, please feel free to ask. I'd really appreciate any input.
Thanks in advance.
By the way, I currently have Revolution JB in my pone.

I think you have to enter the apn settings for your carrier. Google for it. Go to settings, wireless and networks, mobile data, access point names, and enter your APN settings.

Most Roms will be able to use mobile data straight off the shelf if using a known, big carrier, for example T-Mobile, however if your using something more local, something not as well none, then you need to add the APN, if your on contract or PAYG with a different company that provides your network service, like TALKTALK uses vodafones, you need to add it otherwise it connects to vodafone, and uses vodafones APNs which, will not work.

Gotcha. Now I know for future ROMS. Thank you @penguin449 :thumbup:

[ROM][5.1.1][UNOFFICIAL] AICP v10.0 for m7spr [10.3.2015]

UNOFFICIAL AICP for the Sprint HTC One​
Since @superfes is no longer using this phone, I figured I would post some unofficial builds of AICP (Android Ice Cold Project). The previous thread is intended for closure, so we can use this one. To be clear, I'm only compiling this ROM and will not be troubleshooting specific issues. I will do my best to troubleshoot, but no guarantees. Any help on this front is appreciated - I'm new to this and am interested in continuing to learn.
I'm planning on putting together a build once every week or two for personal use and will share that with you guys.
Obligatory disclaimer: I am not responsible for any trouble you may run into with flashing or otherwise using this ROM. Just because it is working well for me does not guarantee that you will have the same experience.
For those of you wondering what AICP is: http://aicp-rom.com

Build notes
10/3/2015
- Fresh build from 10/3
- Tested service / data when moving and no issues
- Remember that I am not troubleshooting specific issues. I'm not a developer. If you wish to post a logcat or anything like that though, feel free and I will take a look but not necessarily be able to provide a solution
- Yes, the digital roaming display is still there. In fact, when you see digital roaming, this is a sign that you are in service. 'Sprint' shows up when you are roaming so it is backwards.
9/27/2015:
- Didn't make clobber so build that hasn't been updated since 9/19 does not show an update (i.e. build will say 9/19 in many places since that was my last full repo sync). For future builds I will do this but didn't feel like waiting that many hours today
- Cherry-picked tdhite's commit from PAC ROM: http://review.pac-rom.com/#/c/13403/
------This has fixed the com.android.phone crashing problem + service being dropped
------ Usable as a daily driver again!
- From a full day on this ROM it's running smoothly and without errors
- 'Digital Roaming' display-only issue persists (been there for a long time now - no surprises here), and it is not indicative of actually roaming. Go into settings / about / sim status to definitively determine what your service status is.

Reserved for now
Appreciate any feedback you guys have too

I'll give it a try and let you know.

I couldn't get a solid connection. It was roaming and when I toggled the network type to global, I lost connectivity. I toggled back to CDMA/LTE but still no connection. I toggled Airplane mode. Still no go. I then changed it to Global and got a connection finally, but it was still roaming.
I hope this helps.

Same issue I've noticed everywhere, no proximity sensor feedback when in dialer!
I'm not pushing the power button every time I get called or I make a call. Only reason I'm still glued to 4.4.4.
Tjis is my 3rd m7 on kk and lp Ota, all 3 on both revisions, same issue.

The digital roaming issue is cosmetic - that one's to be expected (see build notes; you are probably not roaming). As for the connectivity drop, I haven't run into that. If that's happening infrequently and you can deal with the display issue, this ROM should be otherwise fine for service-related actions (calls/texts) in my experience over the last couple of days.

Yes, that one is pretty annoying. I have also noticed it on AOSP LP ROMs including this one and just deal with it. Sorry to hear that's holding you back. If there's a fix out there and I come across it, I'll be sure post about it and add to the ROM if applicable.

You can port camera stock m7?

First of all, great ROM! Have used AICP on my Nexus 4 and my TF300T in the past and it's always been a nice, stable ROM. Just got one question about non-market apps. I've been unable to install any, though I do have the option enabled in the Security menu. From what I've been able to tell, I can start the install of non-market apks with no problem but then the install screen closes by itself and once or twice, I've seen a pop-up that says something about Anti-piracy software activated. Is there any way around this?

So I need Gapps with this ROM?

How about MM?

Any aicp work?

Just wanted to stop in and say thank you for uploading this to the site. I have had a hard time finding a good daily driver and this is perfect for my needs.
If you are still building weekly for your own personal use i would greatly appreciate you uploading here as well.
Also I like the inclusion of more cpu governors such as smartmax_eps, has been great for pokemon go
