As the title states....
When I had a Galaxy S4 we were able to cross flash ROMs (e.g. use an AT&T ROM on a T-Mobile device). The ONLY stipulation was that you needed to flash a T-Mobile KERNEL after the ROM flashed or the phone wouldn't work. Would this be the same concept for us with the G3? I don't see any kernels at the moment so I'm assuming it's a "no-no" to flash one of the other ROMs but once we start getting custom kernels I'm assuming we're good to go.
Would this be correct?
Not sure with the G3 but make sure the first thing you do is back up your efs. I messed up my G2 flashing a International Rom.

I think we are specifically talking about the LG3 since its by a complete different manufacture and a complete different phones.
Note 3 can also flash international but it get wifi issues, nfc issues, and the fact that it wipes your whole phone.
I'm new to the LG scene as well...so ya, as one mention above they messed up their phone doing so with the LG g2

it is the same as any other phone. the wifi and connectivity issues come down to be a radio/baseband related. you need to flash the correct baseband from tmo to have everything working
yea just flash the correct baseband and call it a day
If you want to flash international ROM just for language you want, you may look at which language T-Mobile version has first.

My understanding though is ROMs don't flash baseband therefore that shouldn't be an issue. So kernel issues... Do we just not know yet?

some custom roms do come with radios packaged..all RUU's come with radios too
Is it possible to change the radio/ modem to work on the d852 firmware?
or possibly flashing the 852 stock firmware onto the ls990?
will this work or will there be a conflict with hardware

I'm not 100% sure but I think they use the same modem. That being said, I wouldn't attempt it without a good backup. Also, I'd start with the modem only, wouldn't suggest trying the ROM right away.
It's definitely not something I recommend unless you really know what you're doing. I don't think it has been tested yet and we're just getting stable network having the right modem for specific carrier so there are chances that it simply won't work.
If you do venture into flashing the ROM, you'll have to change your APNs and device code name everywhere in the ROM (unless you want it to think it's a D852). Same goes for the flashing zip.

Well i have a d852 and it works fine on the fido network. But i got the sprint one and it worked fine before but after i flashed the stock rom i havent been able to get data on it . first my imei number was wrong and i fixed that. But still the same problem. I have the correct apns so im thinking maybe if i flash it to 852, it'll think its a canadian phone and not have a problem. Let me know what you think. Unless i currently have the wrong modem installed.
Also where do i find modems i searched for it but couldnt find it.
Ill post the link to my error

Wait isn't sprint with bell? Or that's fido? Cause if so, you'd have to flash the bell modem.

Derp. Sprint is in US..
I don't think it's gonna work now that I think about it. You can still try but wouldn't have my hopes up.
I don't know what hardware Sprint g3 uses, if it's any different. And if it is, the Canadian firmware won't work.

Hello!
I am currently with Telus and have just unlocked my S3 after purchasing the unlock code. If the phone is on the stock Samsung ROM, I can insert a Wind or Rogers SIM and it works fine. However, on the CM-12.1-20150519-NIGHTLY-d2att ROM, it will _not_ connect to any other network. I tried manually searching for network but it fails with a message like Unable to search networks.
I'm not sure why this is happening or how to troubleshoot this. I would prefer to stick with a Lollipop ROM for now.
The CM d2att wikki page does say that since CM11, we should be using the d2lte version for this phone. So should I be installing the d2lte ROM instead?
Thank you

I installed cm-11-20141112-SNAPSHOT-M12-d2lte and unfortunately you were right. I still can't connect to WIND.
I have another fully stock S3 and I ran the Samsung Phone Info app on both to compare. Under the Firmware tab, the PDA version and CSC version is empty on the phone running CM11. Please see screenshots attached which shows this.
Also, I ran the SIM Toolkit app, tapped Manager Services and it gave me a ME returned a temporary error.
Any help would be greatly appreciated to troubleshoot this. To me it does not make any sense that on a unlocked phone, with stock or custom ROM, Telus (this phone was locked to Telus originally) connects just fine. With stock ROM, I can connect to WIND and Rogers but cannot connect to either when running a custom ROM
aaaaaahhhh !!!! @audit13 , hhhhheeeellllpppp !! (please) :what:
"all i can really do , is stay out of my own way and let the will of heaven be done"
The case is missing because there is no carrier customization on a custom rom.
It was my understanding that wind uses aws which the s3 does not natively support although there are hacks to enable these frequencies.
I am not sure how it could connect to wind on a stock rom.

Hello Mr audit13! It's not just that I can't connect to WIND when runnning CM11, I also can't connect to Rogers. Does that still mean there is a frequency issue?
Edit: Looking at WINDs website: (http://www.windmobile.ca/my-wind/faq/devices)
"The WIND Mobile network uses a frequency called AWS, with bands 1700/2100 MHz.(Phones compatible with the U.S. T-Mobile network often work with WIND)"
When you load cm11 or cm12, does your phone show the correct imei?
Which stock rom will connect to wind and Rogers?
Which baseband are you using with cm11 and cm12?
Crazy autocorrect on my iPad changed csc to case
autocorrect OFF. lol. ty for coming to help. :thumbup:
"all i can really do , is stay out of my own way and let the will of heaven be done"
I just did a sanity check. Installed stock ROM and put the WIND SIM in it. It wouldn't connect automatically so I searched for network and it does not show WIND in that list. It only shows WIND Away which is Rogers or Telus I think.
@audit13, you were correct. This phone will not connect to WIND.
I guess I'll just buy a new phone. Nexus 6, here I come!
Anyone in the market for 2 S3's? One is unlocked.
The i747m can connect to wind with a software hack; however, the hack must be applied every time you reboot the phone.
How much for the s3? It's still a great phone.

I see a couple of S3 on sale on Kijiji for 180. Both phones are in pretty good condition. So I am hoping 180 for the unlocked and 160 for the locked one.
Just wanted to let you know that I bought a refurb s3 from koodo for 90 and a refurb note 2 for 180 from koodo. Both come with a 1 year Samsung warranty. They both looked new. You can't find the phones on their website, you need to call the store and ask for stock. I got these phones with no contract, unlocked them via code, and are being used on Rogers and bell.
Oh, hmm. Well, I guess I will try my luck on Kjiji.
Thanks for all your help.
I've checked out kijiji and craigslist and the prices are similar to your asking price. Many people don't know that Koodo sells refurb phones and it was just a matter if luck for me when I got the phones. They weren't even for me! I've been using an old HTC One X from Rogers for the past 8 months
After reading news that Factory Reset leaves most of the data on the phone (research done at Cambridge University), I am very very hesitant to sell my phones now.

That only applies to the ROMs up to 4.3. Why not just flash 4.4.2 a few times, encrypt, decrypt, re-flash? I'm not positive these steps will make it better but it's the only thing I know of.
For years I've been flashing ROMs on many different phones and I've just now started having this problem on my VS995. When I boot up, I get s notification saying no sim card, emergency calls only. After 45-90 seconds it goes away. I don't really have signal, but I can make a call.
Do I have a bad sim? Can I just take it to best buy/ verizion and get a new sim with out them asking a lot of questions? Sorry, this is a new problem for me
TIA.

Im pretty sure its nothing wrong with your sim unless you have like a 3+ year old sim and your baseband looks to be from a lollipop source
Wait, if your running 5.1.1 your not on stock LG OS right? LG OS is only currently on 5.0? That might be normal for AOSP roms since their known for their instability when it comes to cell signal as most of them are built using Cyanogenmod drivers and patches. You still get a data connection right?
I would suggest fully reverting back to stock and seeing if this issue still occurs.

I was having a problem trying to find the modem for my D851 here on XDA. There were many plainly listed for D855 and other models of the G3. I am using Paranoid/ASOP 5.1.1 Rom and I accidentally flashed a D855 radio. Rookie mistake, I know... And thought I backed up the modem along with the system files. Well I didn't and lost my imei, apn, signal and all... So while searching and again not obviously placed easy to find I read a thread and found one, flashed it, and it returned everything to normal without having to flash back to stock rom and blah blah blah... From what was listed, this for L 5.0 and up.
1. Boot phone into recovery, preferably TWRP
2. Flash the modem zip DOWNLOAD: https://www.dropbox.com/s/xz26z91hej9ryz3/LGD851.20B.MODEM-iNb4TMO.zip?dl=0
3. Reboot
I didn't make the radio, nor take any credit for its creation. I'm just trying to make it easier for T-Mobile D851 users on Lollipop to find incase they have deleted or lost theirs like I did...
I am not responsible for any issues or problems that may be encountered by using this.
I hope this help those in need like it helped me... Please let me know...
Im currently having a major issue with the lollipop update. I had my d851 with t mobile and I wouldn't lose lte when I would make a phone call... I currently switched to metropcs and now when I make a phone call I lose lte and my signal drops to 4g. I tried everything... APN, restoring the phone, called metro like a thousand times and nothing. Any help would be greatly appreciated.

Flashing the 30D modem seemed to help quite a bit, the signal will drop to 4g while you're on a phone call but the data is alot faster. Give it a try, it worked for me.

Well, I went camping over the weekend and of course the phone dropped service again. The cell signal was weak and the data was almost non-existent. Luckily I brought an old phone, re-activated it, and was good with LTE signal. My question is would flashing a different modem help? I have the LG-D851 with SW version D85130e so I assume that has the 30e modem. Is that correct and would the 30d modem be better? Thanks.

No idea. Could be something else (mechanical) causing the issue. 30e is the latest for our phones. You can also drop it down to 30d & see if it is any better.

That's what I was hoping to do but was trying to see if there was a way to just install the 30D modem instead of loading the entire phone with the older SW version and having to re-install all of my apps. I downloaded the modem file but after doing some research I couldn't figure out the procedure to install it. I saw a few videos about a TWRP recovery but I prefer not to root my phone. If I have to root it in order to get it working then I will...I just wish I could figure out what the issue is. I saw a few other people mention issues with the LTE setting defaulting back to WCDMA/GSM (which I experience) and they said the 30E modem could be the issue. The phone was just wiped clean a few months ago before I bought it from the previous owner.

yeah without having root, your options are limited. If you own the phone, I would say go for it, if you are leasing it, then take it back to where you got it & tell them it's reception sucks.
I own it and bought it second hand. According to the previous owner he didn't have any issues with it but who knows. I assume if I root it and load the 30D SW I will have to load everything from scratch? Is there an LG backup program for this phone? Thanks for the help.

I have the TMo version (D851) & the first thing I did was root it & install a custom ROM to get rid of all the Tmo crap that is stuck onto it. ugh! I don't use my phone all that much for calls, mostly emails data & music playing, so losing the stock Wifi Calling function wasn't an issue for me. Currently on the OctOS Nougat weekly builds, tremendous ROM, great battery life fast & smooth & decluttered. Since you already own the phone & do not have a warranty, you've nothing to lose here. Do some reading in the threads on how to do it, you'll be very happy once you see how much better your phone can be. You put on it only what you want to put on, less junk, less memory hogging.
