Not longer seeing telus

Hi All,
Not quite sure what happened here.. Upgraded to latest nscollab yesterday, everything was working fine. Decided to try the "Antennas" app to see if it'd show where the towers are near me, switched to 2g mode, played around with it a bit, switched off 2g mode and now my phone does not see telus at all. When I go into search networks, telus simply doesn't show up and my phone stays in emergency mode.
It sees rogers fine and is able to connect to rogers with a friend's rogers sim. I've tried my telus im in other phones and it works fine, other people's telus sims in my phone don't work either.
I've tried reverting to an earlier backup as well as going back to a stock backup. I've also tried reflashing both the kb1 and kb3 radios, no luck.
Anyone know what might be the issue here?

both Telus / Bell do not have 2G
they only have 3G, as in the VOICE only works via 3G
it was the same using the SGS i9000

Did the rogers SIM work on 2G (Edge) only? I am guessing Rogers and Fido will work, but only on 2G
Same happened to me, on Fido, my phone could no longer connect to 3G...Only 2G after playing with settings. I returned the phone
The reason why Telus-Bell SIM would not work at all at this point is that they only support 3G...

That makes sense, but i don't have it set to 2g mode anymore. It should be seeing 3g just fine.

maybe try to do a factory reset default?

Just tried that, nothing. I think that's the same as a wipe data in recovery?
I've tried:
- Reverting back to a stock backup
- Reverting to an earlier working backup
- Doing a factory reset on both of the above
- Reflashing the radio on both

This just happened to me, I switched to 2G and got nothing but com.android.phone quit errors, now I can't get back on 3G. Flashed radios, data wipe, everything... wtf... it's back to stock now and still can't get on Telus... double wtf...

Christ... finally got it... my head hurts from all this reading
For some reason it was on the wrong band. Do this in dialer... *#*#4636#*#*, phone information, menu, select radio-band, USA, and should work make sure its on WCDMA preferred as well under phone information

I had the same issue when in Canada, and forgot I had the band set to Europe (my region).
I set it to Automatic detect, i know catching signal will take longer. But then I dont forget
Sent from my Nexus S using XDA App

i had the same problem since may 14th (sat), thanks for the fix!!!!!!!

Same thing happened here, same solution. Glad you stumbled on it too!
As the title says, had the same problem on my Nexus S (running on Bell), I believe manually switching the 2g/3g toggle in cyanogenmod rom accidentally is what set it off.
Glad you found the solution!! Was maddening for me; knew there must be a way to fix through the UI, but until I fond it, phone was a wifi mp3 player :/

4636 menu ) SOS! NEED HELP!

Hello dear XDA Community,
I have an american Nexus 6P (used with Verizon) which is currently used with a Russian cell carrier "MegaFon"
I had troubles with connecting to their LTE, for some reason my phone just wouldn't connect to the LTE and only stick to HSPA or HSPA+ even though an iPhone near me gets LTE signal just fine, the SIM card is fine in the other phone as well. So I started messing with my phone to find if I could fix it, first I started with going back to full stock, that didn't help, the phone still only accepted HSPA signal. Then I tried multiple ROMs and Stock Images but the issue of not connecting to LTE persisted. Then I found out about *#*#4636#*#* menu (aka Phone Info menu) and I started messing with it, which again did not do any good until I hit the menu button and pressed Select Radio Band (P.S. please don't mess with those settings) where I tried selecting all 3 different "GSM/UMTS" Bands. I tried USA band, Band mode 6 and Band mode 7, but this just broke down my signal completely, I cannot connect back to the carrier network no matter what I did. I've tried factory resetting, flashing radio img's, flashing stock/custom. NOTHING HAD HELPED/WORKED
I'm now stuck with a phone that doesn't work at all, and I'm on business trip so I'm just pulling out my hair for messing with those settings in the first place.
Does anybody know a possible fix to this? How could I go back to what I had before even though I tried all kinds of forms of factory resetting the phone
I really beg for your guys' help
Thank You
EDIT: Found this http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347 gonna try that right now
EDIT2: That modified ROM helped! But I still don't get 4G

Have you tried removing the SIM card, rebooting the phone, then going into the Phone info menu and setting the preferred network type to LTE/GSM auto (PRL)? Maybe afterr another reboot with the SIM inserted the phone will connect.
Also check the APN settings -- they might have changed.

I think I've tried it, I'll give it another try after seeing if flashing this one ROM where you can select Auto Band in 4636 menu that I linked in the edit would work.
APN settings were fine.
Thanks
EDIT: That ROM helped! But I still don't get 4G

Looks like the post you linked should do the trick. Good luck!

code in Huawei *#*#4636#*#*
I have the same problem. My Huawei is Portuguese and the sms work and the internet to but no signal radio. Wen I dial a number tells me no radio found. Can somebody help me? Thanks

Can't switch back to 3G or LTE. Left with only 2G connection.

Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

What he said.
That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option

Have I bricked my G5 Plus?

Hi. Bought yesterday in the UK. Love it.
I was poking around in the secret code menu via Engineer Mode Test Tool. In the menu there is an option to change the radio band, the only choice though is United States. Figuring I could change it back to Europe at some point, I hit ok. Now my phone doesn’t register with any network and there is no option to change the radio band back to Europe.
Have I bricked it? Or do you think it did nothing and there’s another reason?
Wifi still works fine, and I can do a manual scan of the networks and they show - I just cannot connect. This tells me that the unit is seeing the networks just fine and the radio band hasn’t changed, and that for some reason I’ve been locked out?
I tried another sim - same problem.
And of course I have tried turning off and on, factory reset too.
Currently in Dublin, phone was roaming just fine beforehand.
Any ideas?
[UPDATE] I re-flashed the firmware and it's fine now.

LTE does not work anymore (G600K)

Hi All,
I bought this LG G6 (G600K) from HK a month ago. It was working perfectly until few days ago when the LTE stopped working. In the notification bar I can see LTE, but there is no data going through. E.g.: messenger shows "Connecting...". Basically no 4G internet any more. So I did my research and these are my findings:
If there is no LTE coverage, the phone switches to 3g and it works - so the problem is only with LTE, but LTE is everywhere nowdays
In this Korea Telecom ROM there is no way to configure to only use 3g (CDMA only), not even in hidden menu - this could be a remedy, but would not solve the issue
Wifi also works
I did Factory Reset twice (also Network settings reset), did not help
I waited for an update from KT, maybe contains a fix, but did not help
I went to my operator (TELENOR Hungary), and they have checked my subscription, and they said everything is ok, but they can see that my phone does not connect to the LTE system.
I tried my SIM in an other phone, and LTE works perfectly
So based on these facts, I can't think of other than the phone has a hardware issue. Do you have any idea how can I investigate further?
Thanks for any suggestion.

Have you made sure data roaming is turned on as you have Korean model, I had to enable data roaming to get mobile data as the device thinks that's exactly what it's doing.

Unfortunately it is grayed out. But 3g works and 4g worked before. I have not changed any settings, just went away.

Did you fix the problem yet?? I also have same situation like you.........

Hi, sorry to hear. I could not solve yet. I went to the 3rd line support of the operator, but they say everything is fine from their side. So I'm waiting for a custom ROM, or I will change my operator. If you can, send back your phone.

Well i just found temporary fix for grayed out data roaming..this method worked to me
download quickshortcutmaker from playstore open app and switch to normal search find roaming click on roaming - global roaming - create... you can enable data roaming from there..
And for manual network switch LTE /3G : quickshortcutmaker - normal view - network -networksettings global
Hope that helps
Sorry for my bad English..

Wow, thanks. This is working as a remedy. You are the hero of the day
