[Q] Updated 80220D no 3G (or GSM) after update - G2 Q&A, Help & Troubleshooting

Hello,
I flashed my phone with the LG tool to latest version as I couldn´t hear that hissing sound in my ears any more. Before I was on 80220B.
Unfortunately, I dont get any data signal...Calling works ...
I tried 2 SIM cards, so its definately the phone (put my SIM to another phone, there it works)
Any one else had these issues or suggestions?
Thanks

Sounds like you may have a phone from another region... try setting the APNs manually.
Otherwise, FULL reset and flash again.

The upgrade was for a phone sourced outside your country (or region in fact). Possibly when you bought it, someone flashed the local firmware.
This seems to happen a lot with phones bought via Grey vendors.

I know what you mean, I am in Germany, bought the phone from a "normal" online shop (new) and got a polish version. Now I flashed the german version to it which is the cause I think.
Thanks for clarifying

[Q] Please help! I may have ruined my phone

Hi all,
I've recently bought an HTC Legend from Virgin mobile, unlocked it, and now trying to get it to work on Rogers. After I unlocked it, I tested the phone by placing a call. It worked.
Then I got excited and decided to root it and load a custom ROM. I did not read the comments about the ROM and it turns out, the ROM changed my radio. When I go Network Operators on the phone it now says, "Your SIM card does not allow a connection to this network".
The ROM I used was Rodriguezstyle MoDaCoMoDrOm V2.3
I thought I lucked out and found the Bell RUU from Shipped ROMs but that didn't help at all.
I got too excited when I first received the phone and didn't take down the radio info before I starting messing about, which was stupid on my part.
I am freaking out a little and not sure what else to do. I had asked a friend to bring this phone over from Calgary, AB for me because they don't sell them in Winnipeg, MB where I live so bringing it back to the retail outlet is going to be pretty difficult.
Please, please, please help me. I apologize in advance if I am posting in the wrong spot.
You may be able to return for "warranty" purposes. Just lie through your teeth
Or you can do it the hard way. Just flash all the radio that was released. Try one by one and you might hit the spot. Try 7.08.35.21.

Haha! I wish I could. The retail outlet where the phone was purchased is in another province and is about a day's drive. They don't sell the device in the city I live in.
...although I could give it a shot here and ask them to ship one over? I'll save that as a last resort

I think I might have to try this method. Do you know if there is a repository of all the radio released for the Legend?
I've flashed the radio suggested, 7.08.35.21, still nothing. I was reading in another thread that it could be my SIM card? Strange how I was able to place a call when the phone was first unlocked. ...but it IS about 3 years old.
I'm not sure what else to do. I just may have to plead with the retail stores here. Hopefully they can ship me a new one

Whoops! I meant the SIM card. Sorry about the mix up.
I just got off the phone with Rogers Tech Support to see if there was anything wrong with my SIM. He said that the symptoms I am having seemed similar to that of a locked device ("Error while searching for networks" and "Your SIM card does not allow a connection to this network" when in Settings > Wireless & networks > Mobile network > Network Operators).
He mentioned that by flashing a new ROM, that could have re-locked the device. Sounds strange to me but if this is true, how do I find out which carrier the device is now locked to? I am now running the rooted ROM found at the root tutorial TheUnlockr.com.
The phone is not prompting me with an unlock code input like it did the first time around. Is there a way to bring up that prompt again?
Please and thanks
Hi all,
I hope everyone had a great holiday.
A few updates:
- tried flashing different ROMs
- tried toggling radio and autosync
- tried flashing a new radio
- tried using stock Bell Mobility RUU
- contacted Rogers and got them to reset me on the network
Still nothing, not even voice. I've been obsessing over this and it's driving me a little nuts.
rajasyaitan has suggested flashing all the radios that were released until I hit something that worked. Is there a repository out there?
I don't know why, but it never occurred to me to ask for the stock Virgin Mobile Canada RUU until now. Does anyone have it lying around somewhere or knows where I can get my hands on it? I can't find it online anywhere. If not, is there a way to pull it from a phone that is running the stock ROM? I'm not sure if it is the same as the Bell Mobility one but I thought I should start from the very beginning.
Any help will be greatly appreciated.
Thanks
Please my phone is having the same exact problem, it's not working! I'm with Virgin Mobile Canada and I cannot connect to my carrier telling me my SIM card is not allowing me to connect to them! Please someone help! I used this Rom called Stock Froyo ROM for the HTC Legend with Online Kitchen from Modaco.
And when I loaded it, it wouldn't let me access my settings and then I loaded my backed up Rom, and now I can't connect to my Mobile Carrier. (Virgin Mobile Canada) what should I do?
Just a thought here, but is it possible that the phone is SIM locked again? When you unlocked it, did you have to flash another radio FW? Did you try "unlocking" it again?
do you have the phone set to gsm only or something like that? should be set to wcdma only (for bell/virgin/telus)

Actually my phone is connected now, I had the same problem, I did something with the recovery before the problem was magically fixed, I went into recovery, and went down to "Backup/Restore" and I went to "Restore Google something sys..." (Restore NOT backup) and when it was done, my phone was working again, but I was on a different Rom other then the one that caused the trouble. That's what I did and it might have worked because of that I really don't know. And my phone is on "GSM/WCDMA auto", and it's connecting just fine.

No SIM detected - Stock Rom 4.2.2

Hi guys, came here to ask for your help and advices as im really desperate. Im a common reader of this forums but sadly this is my first post.
My N4 stop detecting my MicroSIM, i went to my carrier to ask for a replacement (they cut a SIM into a MicroSIM) and the problem still remain.
Im on stock rom 4.2.2, never rooted.
Im from Argentina (the new Pope country , and a friend bring me the N4 for me. Since i have it (begining of february) everything works fine, lose signal every now and then but nothing to worry about. But suddenly, the last monday stop detecting my SIM and there is no way i can make it work.
When i look for available networks in my phone after a while the 3 carriers of my country appears but when i tap on my carrier and after a while of thinking this messages pop up: Your SIM doesn't allow the connection to that network
In the APN section of my N4 there is nothing, and i can't create a new one. Before this happen i could do it.
Here's the things i've already tried:
- Switch on/off and Airplane mode on/off
- Replace the MicroSim with another of the same carrier
- Factory Reset from configuration options in the device (with and without the SIM on it)
- Factory Image Reset from Google 4.2.2 JDQ39 (with Google Nexus 4 Toolkit v1.3.0, thanks to mskip for that piece of work)
Here's the things im not tried yet:
- Put a working MicroSim from another carrier (it's really hard to fin someone whit a microsim here, that's why i couldn't do it yet)
- Change baseband (in another forum told me that but i don't know how to do that)
I really don't know what to think, it's the IMEI? the radio? the baseband? the 4.2.2 update? the carrier?
Hope someone could throw me a bone, a lead, something that help me solve this problem.
Thanks in advance and sorry for my poor writing.

Most of the problems I read like this are solved by using a real micro sim. The N4 doesn't like cut sims.
Correct, flashing a rom will do nothing but replace a kernel. Think of ROMS like an OS of sorts. But what you are describing, will require an uncut micro sim to verify if it is indeed your sim or not.

Yes, you are right. I'll try to verify with a real micro sim first, but if i do that and the problem persist what would you recommend me to do? considering the things i've already tried.

The N4 is known to have issues with cut down SIM cards. Most likely they are not seated correctly and not making proper contact.
If an actual MicroSIM does not work, you would need to RMA the phone (bad SIM slot).
FINALLY!!!! all of you were right. I went to my carrier this morning and requested for a real micro sim, that simple solution solved my problem.
That's what i should have done in the first place, i feel like a noob right now but i do not care, im a happy noob today !!!
Im really greatful to all of you guys, thank you very much.

Glad you got it working!

Had to get my phone unlocked, now 3G doesn't work.

I live in Bangladesh and got my Note 3 N9005 from Saudi Arabia. My parents were the one who got it for me. They used it there for making a few calls so that hopefully the phone wouldn't be region locked when I got it in Bangladesh. However, that didnt work and the phone was locked the moment I put in my sim card.
So I tried Chainfire's region lock away app hoping it would work but nope, that didnt work either.So I took my phone to a local shop hoping they would know how to disable the lock. They said it would take some more time because some files were missiong or were altered in some way because of Chainfire's app. Anyways, they were able to fix it but it took some time.
However, I noticed a new problem when I put in my sim card at home. I can't use 3G now. I only get Edge speeds now. I assumed the phone should automatically connect to 3G but nothing is happening. There are no settings either. WCDMA doesn't work either. I just get an error message when I select that. So I'm in a pinch right now, can anyone help me out here? Is there any way this issue can be fixed? Perhaps if I update to 4.4.2? I really don't know what to do here guys

If I do that, will the region lock come back? And can I flash another region's firmware like Poland's 4.4.2 or should I not mess around and just get my region's one?

[Q] Not registered on network

Hi there!
I bought a Galaxy Note III in Thailand, unlocked, and I am trying to use it in India, Vodafone. Data is working perfectly but when I try to register it on network is not possible. I already went to the company and replaced the sim card. Same problem. When I was in Thailand it worked perfectly, even I tried in Nepal and it was working 100% too, so phone is ok. Somewhere I read there is a new system to avoid bringing phones form one country to another. Some help would be apreciate. Thanks in advance. Be happy

maybe you should try another network sim card or go into the settings and search for networks and then hit automatic
Then maybe you both need to flash your own regions rom?
Check your imei number, does it different from under the battery? Your phone probably been injected with superimei which did not work with gsm mode (it work in wcdma). You need to find a repair shop which has the SPT BOX to repair your gsm connection.

Mat if u search in indian forum same problem of yours faced by others, your phone is unlocked threw super IMEI which works in only 3G, u must go to Good mobile repair shop who has some sophisticated tools to fix your problem, keep flashing different ROM etc will make things more complicated as this is a known problem, as someone suggested follow below link.

No signal on stock rom

So,
I was using my XT-1563 on a CyanogenMod in one of my local carriers. I bought a new phone and decided to sell this one, so I went back and installed stock rom. So far everything was ok.
The problem came when the person that was buying it tried to use her simcard. The phone didn't show any error, but it never connected to that network. Then I tried another sim from different carrier and it didn't work either (but it does work using my old simcard). It recognizes there's a new simcard, but fails to connect, only allowing emergency calls.
I've been trying all day to fix this. I have flashed nearly half of all the stock roms available, obviously starting with those from my zone, but so far none has worked.
I also tried the simcard into my new phone and it works just fine.
So, I know the following:
- The simcard is ok.
- It's not a signal problem (I have tested it in different parts of the city and zones I know have very good signal).
- The phone works using a simcard from one carrier, but not the others (and it doesn't ask me for some unlock code).
Thanks in advance for any help, it'll be greatly appreciated.

So, did you ever carrier unlock the phone? I realize it's not asking for a code, but you never said you actually unlocked it.

At this point I'm not 100% sure.
When I bought the phone it was supposed to be unlocked (I got it from someone else) and I'm pretty sure it was, because it was originally bought for one carrier (Entel Chile) and then I used it with another one (Wom Chile). By law, every phone sold in Chile since a few years is mandatory unlocked and this one is not that old (2015).
Right now it only works with Wom Chile, even tho I've installed Entel's stock rom. I think it's some baseband issue from what I've read, but I can't be sure.
P.S: Sorry for bad english.
Yes u r right
i used cm14 on xt1562, i'v feel my network was drop around 30-40% specially on Reliance JIO 4G VOILET.
Over all - rom is good for enjoy but not for stability
