Bell e973 unlocked on rogers...

Can I flash a rogers e971 modem on my unlocked e973? Not sure if the hardware is different (don't want a brick). I just thought signal may be better if I did this

Yup.

Hi Crixley, Everyone,
I have an E973 which was originally a Bell phone. I installed the stock 4.4.2 months ago (http://forum.xda-developers.com/showthread.php?t=2771440) and it worked great. However, today I wanted to give the phone to my brother, so put in his Rogers SIM in the phone, it just says "Searching for Network" and never connections - it detects the network in the "Search Network" options, but says "No Service" if I select Rogers (or any of the other networks). If I put my Bell SIM in, it works immediately and if I put my Rogers SIM in a Xperia X1 or my Nexus 5 it also works right away.
Does anyone have any ideas? I factory reset and wiped the phone to try to resolve it but its made no difference. I also tried installing the E971 modem based on this thread, but also no change to the errors (though my Bell SIM still works fine after the flash).
What it says above suggests it should work - I do not need LTE, just basic phone call/texting service.
Thanks a lot,
Peter

Your phone probably doesnt supprt the network frequency that your carrier runs on

before flash works OK, problem with network was after flash official ROM

same problem here before it was fine after flashing cellular service keeps on dropping

Hi guys, I'm facing the same problem. Did you find solution?

My LG G3 only connects to Edge network

Hello guys.
After a couple of days reading on the internet without success I decided to share my problem here.
I bought a LG g3 D850 32 gb on eBay, once I received it I was so happy enjoying the 4g LTE network, the speed was amazing.
Regrettably, one day all this happiness disappeared, now I only have Edge connection, I don't have 3g, hsdpa or 4g, I only get the awful Edge.
I have tried using my sim card on other phone and I get 3g and hsdpa (that phone does not have 4g) so the problem is on the G3.
I have to say that I have the phone with the stock rom and the only change I've done was to root it with kingroot and deleted (disable) some at&t apps. I thought this was the problem so I restored to factory defaults but the problem did not disappear.
I was thinking in to return the phone but I am in Chile so is a little hard.
I will be grateful if some one could help me with this issue.
I will be waiting for your comments
Thanks on advance

What model number/version/baseband/etc.
What's your base network and are you sure your APN settings are correct?

Hi Nick,
This is the Software info:
Android Version: 5.0.1
Baseband Version: MPSS.DI.2.0.1.c1.13-00058-M8974AAAAANPZM-1
Kernel Version: 3.4.0
Build Number: LRX21Y
Software Version: D85021r
Security Software Version: MDF v1.1 Release 3
I do not understand what the base network is. Is my cellullar provider?
The APN settings are OK. I didn't change anything.
I had all the connections and suddenly I lost 3 and 4 g and only get Edge.
I didn't change anything. I rooted the phone with KingRoot but I am not sure if the problem started in that moment.
I have made the Factory Data Reset a couple of times and the problem continues.
My Sim Card works fine in other cell phone.
Please Help!!!!

I had the same problem when I switched the operator. Went there and the man there tried everything but nothing helped. Last thing he suggested was to do a software update, did it an 4G speed came back

Yes, your cellular provider. What's your cellular provider and what's your APN? Is your sim from AT&T, a foreign provider or from a Chilean network? Does the APN match the SIM provider's APN?
I'm thinking that it's either an APN problem or a band switching problem (since you disabled some AT&T apps) or you just ran through your allotment of 4G data under your contract.
If you've tried your SIM very recently in a friend's phone and it works just fine, then it's probably not a data allotment problem.

I am using a chilean provider with the correct APN, the same I used from the first day when 4g were working fine and the same.
Yesterday I tried mi sim card in other cellphone and I got 4g without problem. I checked the apn and they was the same.
Now I tried with tho different ROMs, I changed the kernel and the modem and I'm still get only EDGE :crying::crying:
I do not know what to do. I think the cellphone is bad

I'm guessing that you may have disabled something when you were deleting the AT&T bloatware. You've got a D850, right?
As @trickie69r has mentioned in a previous thread, try downloading your KDZ direcly from LG's Servers using: http://csmg.lgmobile.com:9002/csmg/b...XXXXXXXXXXXXXX
(Replace XXXXXXXXXXXXXXXXX with your own IMEI, which can be found by dialing *#06* in Dialer)
Take a screenshot of your About Phone > Software Info tab before and after and see if anything changes.
Buena suerte!

Thank you Nick.
I have flashed some Roms, and the problem did not solve.
I have tried to download the stock rom but I can't download it from the link you send me. I can't find D850 stock rom.
Do you have other link to get it?

Did you try using the ROM in this thread, or just installing the AT&T apps to see if those worked?

Yes I tried that rom and stock kit kat and nothing works.
I think the cell phone is defective because I have other LG g3 and works fine

H815 can't make / receive calls but sms / data works great?

It's a UK vodafone G4 which I got unlocked and was using my O2 sim without issues. I ported the O2 number to iD Mobile (three network) and can use SMS as well as mobile data but calling doesn't work at all.
I put a Three sim in and it's exactly the same issue. The iD sim works fine in other phones. Other sim cards work fine in the G4. It's just iD and Three sims that won't make or receive calls.
I since used LGUP to install a kdz file (V20c-234-15) in the hope anything vodafone will be removed but that didn't make any difference. In the phone Settings if I check Network Status it shows the iD connections, in Status it shows Unknown Phone Number, in Network Mode it displays 2G/3G/4G, APN shows all correct iD settings. If I search for Available Networks it displays all the usual UK networks and only lets me select iD network.
Customer service said wait a few more days after porting and suggested a faulty sim (yet works in other phones) but after both iD and Three sims showing the same issue I've not much hope in their suggestions.
I know others that bought the vodafone G4 and unlocked it for Three haven't had any issues. I only found 1 other post online that has the exact same issue as me but their post hasn't updated since last month.
I don't know what to try. Other sims work, just not iD/Three. Any ideas for me to try?

I've since tried another kdz file for lollipop as I know for sure the sim worked before the number was ported before the phone was upgraded to MM.
Still doesn't work for calls, only data and SMS.
Can anyone offer more suggestions to try?

This is a weird problem maybe your problem is modem or wrong kdz file. Downlaod right file and flash again and be sure that you click refrush that is makes wipe in LGUP.(I use LGUP)

Thanks,
I had this problem with stock rom too though. I only started trying more kdz files in the hope that might work. Issue started the moment my number ported from O2 to iD Mobile.
Wierdly the phone doesn't like Three network sims either now and those worked fine before the number port happened.
Am really confused

no network available. only getting AWAYs

as the title suggests, i gotten the lg g3 from a guy off kijiji. He was with virgin mobile its d852. i payed to unlock the network and put my WIND sim in. I unlocked the network when there was no sim card. I put my sim card in but the only available networks i was getting is all away.
i swapped the sim thinking it might be that. no luck. i checked to see if this was blacklisted, it wasnt.
im running on cm13.
could this be because the bands are not activated? IF so, i tried following this guide http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 but it didnt work. i couldnt get the right driver to show up.
Also could it have been impacted by unlocking the network without the sim card in yet?
if someone can help with skype to speed things up for live debugging that would be greatly appreciated. you can add me at [email protected] for skype.

update: so i called wind to see if they can register the phone as on the network and they said they cant put the imei on the account. what does that mean?

Wind needs d852g... Not d852... There is some old threads of people converting the rom and modem to d852g which unlocks the band required for wind.... Search for that, no idea if it works or not tho
Sent from my LG-D852

i had a g3 before and it was d852 and it worked fine...
like i said its d852. i couldnt even flash d852g in.

swapped sim cards with a friend who is also on wind and my g3 couldnt get service but my sim card worked fine on her phone.

another update flashed 852g firmware on my 852 no change. i did so with 852g firmware and 852 dll.
i also flashed 852 tot with 852g dll and still no change in network.
called virgin mobile and they see that the imei is no longer on the account.
this is such a pain does anyone have anything to help??? is there an easy way to view all the bands the phone currently have??

anyone??
