[Q] {10-25-2012}{Rom}{ICS} Official Global CM9

* Unfortunately, I'm having the same problems with this ROM on HSDPA that I was having on aeroevan's ROM. GSM is found immediately on boot, however, HSDPA is very flakey. It will succeed in connecting every now and again, but then randomly drops the signal and won't reconnect. I thought maybe I just had a weak 3G signal where I was testing, but I have a BB Bold for work as well and that can easily maintain a 3G connection on the same network. I also had no problem way back in the day with CM7.2, but that ship has sailed .
Also, when the phone is in WCDMA preferred mode, after a while the phone will lose all connections (usually after a reboot but not always), including to GSM and when I go to reselect my network operator I get the message "Error while searching for networks". No matter how many times I reboot the phone or switch to "GSM Only" or "GSM/WCDMA auto" it never lets me again select my network provider.
As I said, I ran into the same problems with aero's port, so its not specific to this ROM.
* Situation are me after uproom (http://forum.xda-developers.com/showthread.php?t=1932573), spent two days lost wave, down to the original room (fullwipe finished down about 2.3.4). So lose the 3G network always in global mode (global), 3G users they will never be, but 2G ok (you spend vina sim and have installed APV vina). The physician who has experience helping hand factories. Thank a lot.

I don't known?
I do not understand.Specific guidance for me? please!

BTW, I don't understand this part.
I would suggest reading through the entire thread of Aeroevan's rom that you were describing as well as the Global CM9 thread. During your reading you may find and answer in there. I have found more answers that way than waiting on someone to direct me there anyway. That is all the advice I can provide with my limited knowledge.

Help me

I installed your room ( {Rom}{ICS} Official Global CM9), after 2 days my phone is not network. I reinstall the original room 2.3.4 but only use 2G when I used dataroaming; completely unusable 3G & network global mode always (I fullwipe data before reinstalling room 2.3.4 & APN properly installed).I then set your room again, but as I said above condition.Please help me how to be able to use 3G

Ok, I don't know if anyone else is having the same problem as you. I hope I don't offend you but I am going to take a guess and say that english is not your first language as some of that is difficult for me to read and completely understand. From what I am gathering is you can connect to your carriers network but only on a temporary basis. Here are the steps I followed to connect to Verizon's network using {10-25-2012}{Rom}{ICS} Official Global CM9 - After a full wipe and clean install and after initial setup I went to (doing this from memory as I don't have it installed at the moment) Settings --> More --> Mobile Networks --> chose CDMA w/EVDO --> Exit out of settings and rebooted. When the phone booted up it recognized the Verizon network and all service and data was all working, I didn't have to change the APN settings at all. If you are still having trouble staying connected I suggest you check the version of radio you are using and consider updating it. Here is the radio thread: http://forum.xda-developers.com/showthread.php?t=1134451 I don't think I am the best person to assist you but just telling you what I would do if I were in your situation.

3G disconnect, only use 2G (GSM). Help me!

I have been having the same problem. Flashed CM10 after full wipe, mobile network (for verizon) is CDMA w/EVDO, tried rebooting and switching and wiping and re-flashing but I have no wifi and bad 3G. When I revert to stock everything is fine. How can I fine the latest radio for CM10, I didn't see any JB in the thread link.

[Q] Wifi and data connection issues with CM11-20140122

Yesterday I upgraded my Galaxy W to CM11-20140122 as per the instructions on the developer section of this site. Everything went smoothly and I connected the phone to my home wifi and update and reinstalled all my apps. No problems. Thismorning though, I'm experiencing wifi and data over network connection issues. For some reason, although I can see the wifi networks and I'm notified that there are networks available, I cannot connect to them - even though I could previously! The same thing happens with my mobile network - the network is connected and I can make calls and send texts but I persistently get 'No service' and no data connection.
If anyone has any ideas how I fix this I'd appreciate it? Is anyone else is having the same kind of issues? I was thinking of upgrading to kernel 3.4.80 to see if that solved anything...

ok, so after three hours sat within range of the wifi, suddenly the phone has decide to connect to it (as I wrote the above post - maybe its feeling threatened! ). I wonder if this is going to be persistent behavior or wether it was a 1-off.

Interestingly, my wifi seems ok now, but I'm still not getting any packet-data connection. After a recent phonecall I got the message 'No Sim or Sim Error' (although it let me make the call). Then I look at the details under 'About Phone' and 'Status' I get the IMEI number, it lists my phone number as unknown and Mobile Network State as Disconnected. Interestingly, it doesn't seem to be connected to the right network either. I wonder if the packet thing is actually and issue with reading the sim-card?

fix
How did you install the rom ??
I think restarting the phone after switching to 2g fixes the issue
it only happens on wrong recovery options (dirty flash)
use this "clean to install a new rom"

I followed the instructions from this thread: http://forum.xda-developers.com/showthread.php?t=2588495 to install the rom. I used Odin 4.43 to install ancora.ops, then factory reset and cache wipe, then flashed the rom, then reboot (basically). I don't think there was anything wrong with the flashing process, it all seemed to go smoothly...
How do I 'switch to 2g'? do you mean select my preferred network as 2g?

OK, so I flashed the kernal to 3.4.80 and everything went smoothly. Wireless has been behaving (and was before the update), but I am still getting 'No Service' on my mobile connection. I tried setting my preferred network connection to 2G and that hasn't helped. I can probably live with it if wifi is working, but it is a bit annoying... I guess I could try the 'clean install' link.

Have this problem on DarkCM rom too

Cannot SEND SMS Tried Everything Please HELP :(

All of a sudden today I cannot send SMS.
I was on a really old build of Cyanogenmod12 (April 22nd I believe) as any time I tried to update to newer Nightly builds I lost all Sprint service could not make/receive calls or texts, etc.
I decided I was pretty fed up with CM12 so I decided to go ahead and migrate to AICP. I wiped everything TWICE in recovery, loaded up AICP and it works fine, I get LTE signal, etc. However I cannot SEND SMS, I can RECEIVE SMS I just cannot SEND. I had done some data restores with Titanium and I figured that somehow some way that might be messing with things. So I did another 100% fresh install after wiping everything.... I can send/receive calls, receive SMS but I cannot SEND SMS
I am really at a loss here guys, ANY help would be greatly appreciated

*#*#4636*#*# change it to CDMA wait 30 seconds send an SMS and do *#*#4636*#*# again change it back to late/CDMA n should be ok
Sent from my SM-N910P using XDA Premium HD app

I stayed up all night last night working on this, let me update the thread with what I have done so far.
I was looking at some stockish ROMs and I noticed that there were warnings on some of them stating that you needed to have the Sprint OTA 5.0 update installed prior to flashing, which I actually never got. My phone came out of the box with Kit Kat and I never installed the 5.0 update, I went straight to CM12 5.0 instead. So I had a theory that there might possibly have been some sort of network data profile, etc or something out of that official 5.0 OTA that I never got that was somehow causing me problems. I decided to revert back to complete bone stock.
I wiped everything and flashed the N910PVPU1BOB7 file (MD5 = 7304e42cf0e241553d8db9e3c3eeed81) which was the official Sprint 5.0 OTA. Loaded it up, updated the PRL, Network Data Profile, etc, etc, etc.... everything works (relatively speaking...... TouchWiz sux balls of course). I have LTE signal, I can send/receive calls, I can send/receive SMS... all good.
So at this point I decided to re-wipe and flash AICP, with the emotion Kernel (latest builds on all). Load it up.... same problem as before. I have LTE signal (stronger than on the stock Sprint ROM), I can send/receive calls, I can receive SMS but I still CANNOT SEND SMS
I tried a few things at this point. I tried to manually reset the Sprint network connection on the phone by dialing ##72786#, this did not work, it returned an error "incorrect MIM code". I tried the *#*#4636*#*# that I have seen suggested in multiple places, this also did nothing, it returned an error "incorrect MIM code". I also noticed on the "mobile networks" tab, and this is true for BOTH CM12 and AICP, that it has the setting at "Global" by default and everything works with exception of sending SMS. Now when I click that tab it only has 3 options LTE, 3g, 2g.... for some reason "global" is not an option, neither is CDMA. Whenever I select LTE it automatically drops me from the Sprint network PERMANENTLY until the ROM is re-flashed there is no way to reverse this. I cannot even dial the manual programming codes "*#* etc" as it just simply says "no network service". If I try to automatically connect to the sprint network through the network operators tab it does in fact find Sprint as my provider, however if I click on Sprint to connect it processes for about 2-3 minutes and then simply returns an error of "cannot connect to the network at this time, please try again later". Again the only way to reverse this is to re-wipe and re-flash again which puts it into the unselectable "global" network setting by default where then I will have LTE signal, I can send/receive calls, and can receive SMS but not send SMS.
So that is where I am at, I stayed up all night last night wiping, flashing, and testing different things over and over. Nothing seems to work 100%, except the stock 5.0.1 OTA which is what I am on now. I really hate TouchWiz and for some reason I get a much weaker LTE signal on stock compared to either CM12 or AICP (I have no clue why this is). I am really at a loss here why everything works on the custom ROMs except for sending SMS..... willing to try almost anything to go back to a custom ROM.
Let me know if you guys have any other ideas.

Well great news I have finally resolved the SMS send issue

*#*#4636*#*#

pbedard had tried to help me with the above post (which I appreciate, thank you), and I have seen the same advice in other threads. One slight problem though, he slightly mistyped the manual programming code it is actually *#*#4636#*#* not *#*#4636*#*# which I had tried entering ohhhhh I dont know 30 times? :silly: And it always returned an "invalid MMI code".
I had tried everything and after spending a full day on TouchWiz I was determined to fix the issue so I could go back to a custom ROM. I was even manually creating and deleting APNs, etc. Nothing would work. Right as I was about to finally give up (after literally 12hrs of researching the issue and testing fixes) I was reading the official CM 12 thread and came across the "fixes" post:
http://forum.xda-developers.com/showpost.php?p=57613217&postcount=3
Because I had tried entering the manual programming code so many times I happened to notice that the last 4 key strokes were not what I had been entering. I entered the correct programming code, boom the Phone Info menu pops right up I follow the directions and what do you know send SMS finally works .... wow what a relief, I am on the latest AICP release on the emotion Kernel and everything works like a charm.
Also by setting the phone to LTE/CDMA through the manual programming menu I have the strongest LTE signal by far, full 100% bars at all times (I live right next to a Sprint tower). I have never understood why I only got 1-2 bars on the stock ROM and 3-4bars on CM12/AICP through the default settings. Anyway thanks for help and I will list out exactly what I did to get it working.
- 100% Stock ROM
- CF Auto Root and TWRP install through Odin
- Reboot to recovery
- Wipe Dalvik cache, system , data, and cache
- Reboot to recovery
- Flash emotion kernel (optional)
- Flash latest AICP build (or custom ROM of your choice)
- Flash latest stock Gapps
- Reboot system
- Confirm Google Messenger is the default SMS app (it will already be if you flashed 5.1 stock Gapps)
- Dial *#*#4636#*#* ("Testing" menu screen will pop up, select "Phone Information")
- Scroll down to "Set preferred network type" click it and scroll up and set it to "CDMA auto (PRL)"
- Wait until 3G signal comes online (takes about 10 seconds)
- Change "preferred network type" to " LTE/CDMA auto (PRL)"
- It should take another 10 seconds for LTE signal to come online and you should be good to go to send and receive SMS ! :good:

Preferred network type won't change

Hi,
i'm currently running the latest CM13 and have a problem with the Preferred network type. It stays on "LTE (recommended)" and i can't change it to 3G or 2G. In Phone information (*#*#4636#*#*) it stays on "GSM only" and won't change to anything.
When i go back to LG's Stock 6.0 all changes work. With previous versions of CM13 (first 5 versions i think) it works also.
Does anyone have any idea?

I have the same issue on my LG G4 h815. I cleanly flashed the latest nightly of CM13 (cm-13.0-20160102-NIGHTLY-h815.zip), after first upgrading to the stock 20A image and installed TWRP. I flashed CM13 using TWRP. Then I flashed nano gapps. H+ is the fastest cell tech here, and my phone just can't use the cell network (it seems to connect, but never shows H+ and no data bits are routed). And when I went into the menu to select 3G as the preferred network, it won't let me change it from LTE. It clicks when I choose 3G and 2G, but the selection stays on LTE. When I go into the special menu for radio options, same thing, I can't select a different network mode (it simply stays on the current selection). Wifi works just fine, but cell phone use doesn't work -- no calls, no data. I also upgraded to the next nightly, but it didn't make any difference in behavior.
@Chipstepper Can you tell me which CM13 image worked? I'm going to try cm-13.0-20151125-NIGHTLY-h815.zip ..

Same Problem here on my Moto X 2014. I tried every CM13 nightly between Christmas and early January. I was never able to change the Radiobutton in Preferred Networks and connection in phone information was always GSM only. I also tried a clean flash of the cm-13.0-20160108 nightly, still the same problem.
Now I switched back to my CM12.1 backup where it's working.
Can somebody name a nightly where it's confirmed working?

Network Signal Dropping after update to 6.0M (Poland)

When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:

Same issue. I am on stock 4.4 and mobile network signal keeps dropping on weak signal area. I set to gsm/edge mode to mobile network. But nothing goes fine.

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...

Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
