[Q] At&t optimus g e970 network connection issues - AT&T LG Optimus G

Okay first of all I am sorry if this is not the correct thread to be posting this question.
I have an At&t optimus g and I have been using it in Pakistan for quite some time now, and it worked flawlessly without any major problems. However, now in Canada the same phone doesnt receive network coverage and the service providor says that the connection fequency is not compatible with the phone.
Also, I rooted and bootloader unlocked my LGOG recently using FreeGee but ended up softbricking it, then later using teenybins I did recover it and flash the stock firmware. But I did not flash a baseband (dont know if i need to).
So, I think its either the baseband or radio (some regional problem) causing this problem but have no clue which one it actually is. Any help would be appreciated. Thankyou.

How did you unbrick it?

I softbricked it and went through every trick here at xda but could not unbrick it, did not find the compatible lgnpst. Any way had to finally go to karachi mobilr market and get it done. Hope you find a solution , but do keep us updated.

What band does the carrier use? (850, 1900, 2100, etc) it could be a compatibility issue with the carrier.

This is what I found out
The wind mobile network uses a frequency called AWS, with bands 1700/2100. The LGOG can support both these frequencies, i doubt it is a compatibility issue.
Or is it possible that currently it has no baseband whatsoever, and that i need to flash one? Really confused..

I used the e970 teenybin fix with tSilenzio's Automated LGNPST and the ls970 dll. However that did not cut it for me and I had to go ahead and use the "teenybin(AltBin)" which fortunately got me as far as the recovery. From there, obviously, I was able to flash roms.
Hope this helps.

Op, try flashing the stock att JB radio. If you were using it overseas then it's already unlocked, should work fine for 2g and 3g in Canada.

LG G2 D802 no LTE

Hello, I bought the LG G2 D802 from china, I live in Georgia use beeline as my network provider. The phone satisfies all specs for Beeline 4G LTE.
I did all of the tricks described on XDA-Developers (changing to lte from hidden menu, editing build.prop and settings.db). Software which was installed was HKG. I installed resurrection rom but still don't get LTE signal. What should i do now?
Please help
Do you use old sim card or new usim from beeline ?
I seem to have similar problem with 4G.
It was announced today that 4G is available with phone network so I tried most things and can't get 4G.
The phone company told me to wait for lollipop and then try again.
I will update manually to lollipop and see what happens
I have new USIM card.
Maybe B20 is disabled manually?
I installed EUR-XX stock rom now i can't enter LTE-Only testing menu. Toast appears saying not supported
Hmm try RAT...do
*#*#4636#*#*
Go to : phone information
Set the prefered network to LTE/WCDMA.
do not use LTE ONLY other wise you wont be able to receive sms and call
I tried RAT selection already, i tried all of the methods described here.
I even tried other cellular network which supports 4G LTE, still nothing
Try deleting LteSettings.apk reboot and report.

Tried nothing changed.
I checked the cellular provider's website they have feature which auto-detects if phone supports their LTE band and website confirmed that this phone supports it (B3 1800MHZ).
Maybe the problem is here i opened the LG hidden menu -> LTE-only -> Modem Settings -> LTE Band selection. all of the bands are unchecked. (Check attachment). If i check them up nothing changes, there's no save button, opening hidden menu again show that they are still unchecked even if i check them

Well.. applying a different rom as you mentioned earlier will not change your baseband. Even thought the phone has the specs to work on your area, it may not work if the applied baseband is not compatible.
Browse for a suitable baseband, flash it and report back.

Sorry what do you mean in baseband a modem? I thought baseband was dependent on OS like JB baseband or KK baseband.
If you've meant the modem so yeah I have flashed a couple of modems but nothing changed at all. I'm gonna go to cellular provider's office on saturday.

The software claims that it's D802
That doesn't mean it is a D802 actually... there's a lot of cases of China's bought phones that aren't what they should be.
https://cdn.recombu.com/mobile/images/phones/1282/1378840179.jpg its should we written on the back of the phone D802 (under the logo)
I have the exact same problem as op. My phone is an HKG real D802 because imei on back of phone match, and i flashed an Open euro D802 kdz over original HKG. That said, i dont need 4G as my career doesn't support it but it's nice to find a solution for this problem.
Hmmm, i think what you need is to flash modem / radio zip...
I'm from Indpnesia. As I have D802 and I reflashed the SEA v. 20B modem/ radio then recheck lte/wcdma using RAT menu it worked...
Fyi SEA =south east asia...

Hi,
Yes confirm no lte before i flash the 10B ESA modem
As for update info,
Previous Rom that I used and work on ESA LTE is :
pardus classic 7.7
FR 1.2
Bruce.
This morning I flased Pardus 3.2 sensation black and no LTE found.
i have tried all reflashing :
Stock Baseband, 20h baseband (both kitkat)
Stock kernel / then dorimanx kernel,
Bootloader,
Modem/radio ESA 10b
update:....
It works...I get LTE again.
I knoq its a long shot why dont you try flashing other modem/radio. (At least same network provider and make sure its GSM / CDMA network)... If u get no signal effect than just revert your current modem/radio file again...
Cheers,

I'm not sure I understand. You are no longer on Sprint? If you've transferred to another carrier, you still need to use ROMs built for the LS990 as that is still the device you have.
gsm roms right?

You can set your preferred connection in phone settings, under mobile networks. So any ROM built for LS990 should work.
I have a LS990 on ZV4, official firmware but rooted and unlocked. I am not in the U.S and I'd like to upgrade the phone to official 5.0.1 firmware on ZV8 and still be able to use this SIM. Could you please point me to the right direction on how to proceed? By the way, I'm also getting 'restricted access changed' notification and signal fluctuation using the SIM I'm currently using. Oddly, using other carrier SIMs I don't see that notification. Anyways, suggestions please?

Thank you so much. This was a step up from my old phone because I bought it rooted and sim unlocked so I'm familiar with rooting, just not with a high end phone like this. And rooting is always beneficial.

I understand. Then you did something that broke your ability to connect, right?
Therefore, I suggest flashing the stock firmware again, to see if it fixes what you broke.

Quick Circle help
I asked the following in a thread I created, but it hasn't gotten 1 single reply, hoping you may be able to help me out if I posted it here:
So I recently flashed my G3 with Resurection Remix ROM, which is amazing btw, and the one thing I am missing is the Quick Circle functionality. I've been chasing my tail trying to figure out how to get it added, and all I seem to keep finding is mods for the existing Quick Circle but not the app itself or how to enable it. Help out a n00b please!!

Can I Flash UK/European Firmware onto my South Korean LG V10?

Hi Folks,
Just looking for a bit of advise. I have messed around with rooting and unlocking my phones in the past. I have always just followed guides here or youtube etc so not really having an clear understanding of the potential pitfalls.
I have imported an LG V10 from South Korea and overall am very happy with it. However for some reason it seems to be locked for international data roaming.
Can I get past this by flashing a UK or European firmware onto this phone when they become available ?
What device ID's or Radio's do I need to match etc or basically what do I need to watch out for. This phone can't go back to be repaired if I break it so want to make extra sure its worth it.
Thanks in advance for any help
Cheers
Chris

it always depends if fm chip builted in S808 inside your variant it was phisically enabled or not
i always wonder why manufacturer would add more work physically disabeling something that just do a commong motherboard and then just lock it on the software side or not.
is there an adroid app that could find/see what chip is on my version? (considering it s installed or not)

Ok so long story
I bought an imported LG600S from a guy on eBay who had imported it directly from South Korea I believe direct from SK Telecoms.*
This phone appears to be unlocked for any network here in the UK. *I am using a 3 Hutchison sim in it at the moment which I get calls and LTE speeds. *I have also tried a UK Vodafone sim in the phone and that works fine too.*
My problem appeared when I went to Paris France. My contract gives me unlimited data even when roaming abroad. *However in France the phone would not allow me to switch on data networks. It gave me the warning message which I have attached. *I click the accept tags but still the slider for data network was blocked (grayed out) with a message saying I needed to contact Mobile T Roaming and gave me a link to a South Korea customer service centre . *I tried to call it but obviously I don't speak Korean *
I have tried an unlocking service called unlockscope who gave me a number of codes for my IMEI number. *However none of these codes worked as the phone does not prompt you for an unlock code when you swap sims. *They also gave me a few number strings to put into the dialer to try and force it to ask for a code, however these didn't work either. As an aside the unlockscope company has offered me a full refund and we're very good at trying to trouble shooting my issue. *
So now I am a bit of a loss as to what to do next?*
I need international data roaming for work but can't figure out how to unbarr it except maybe for flashing a different *on the device firmware to get round the block.??*
All help gratefully recieved! **

yes you can test if u want at your own risk I also had f600s and now I am using the latest nougat firmware downloaded from here "https://forum.xda-developers.com/lg-v10/general/lg-v10-f600l-f600k-f600s-android-n-7-0-t3611676"" use the f600k version it works for me each and everything worked perfectly for me.
1. download the kdz
2. use kdz tools to convert it dz format.
3. use lgup to flash (it will not say invalid kdz)
im here to ask something: if you can flash a H960(A) kdz on to F600(K,S,L)...the opposite can be done too without losing features? like put the firmware V30 Nougat in V20 European?
I dont care about FM Radio working or not, only want network and wifi working.

Do you have Att though? I think he's referring to using the att model on another network like I am doing as well. I'm using on tmobile and some users report, after having to edit system configs to be able to even turn on hotspot without an error, that they don't have any data once connected.

Hello Guys,

Normally, Bootloader checks if region code matches before flash.

Its not more of the bootloader, but Antirollback. This works perfectly on older LG's like the G2, G3, G Pro, etc.

H930DS and TMobile(mintsim)

I just got this model of V30+ but didn't know TMobile LTE would not work on it until after I paid. Just didn't read it good enough I guess.
Just wondering if I will still be able to get 4G Data on the phone using TMobile(mintsim) or at least HSPA+ or if its possible to make LTE work on it.
If you flash that to H930G, you'll get s few more U.S. carrier LTE bands. Not all but more.

shows 2 bands supported for LTE on TMobile and MetroPCS. Any chance it could work?

Is this something that has been tested and working?
Yes, but let me find the post when I get home. Unless someone else finds it before me. It was someone who bought Hong Kong H930DS raspberry color and they wanted more US bands.

I haven't got then phone, it's for my friend in the US, she really wants the Raspberry Rose variant, and on Hong Kong firmware only 1/4 4G bands are supported, however if flashing the European firmware means she gets 3/4 bands that's a lot better and I can tell her she'll be okay to get it

Found the answer to this incase anyone ever needs the answer, flashing this firmware onto a H930DS also includes radio.img apparently, which means it will support the same bands that the H930 does :highfive:

Should this be the case I would be so happy! No more having to sell the phone even though I am very happy with it. In the course of the week I will flash the new version and as of 1st May I could give you some first hand experience in the US with an AT&T SIM (currently still in Germany).

So, @TheInfiniteAndroid says yes, and @HeartFist says he'll confirm May 1 -- which is tomorrow.
Thanks. I don't see the thread can you possibly link it please?
Just to be sure the dual SIM capabilities will still function correctly?

If you click on ANY of those posts it will take you to the thread. It's the EU OREO KDZ thread.

I thought you wanted T-mobile USA. Why do you need dual SIM? But you can go to that thread and search for H930DS. LOTS of people flashed that to get Oreo.

here's the same question in that thread:

Question: does it seem to handle dual SIM ok? Can you choose between the two simcards when making calls and sending messages?

Yes just as before. Not much has changed really. I'm in Norway, so having an EU /global ROM makes more sense to me!

Yea I have 2 Sims. Just got the mintsim prepaid for a year witch uses T-Mobile that I was going to use with my essential but that had a fried board in it I think. Artifacting and crashing constantly. Now I just plan to use both Sims in the dual SIM phone for some extra monthly data since I already have both prepaid service Sims.
So if I were to attempt to flash the euro Rom on my hk v30 would it just be a normal flashing process? Require boot loader unlocking? Is there any detailed outline of the process posted up?
alright thanks the information I read through a good deal of the thread at least to where they claimed it was adding support for more us bands.
One other question. After flashing this will I then still be able to receive ota updates and will it be safe to install them?
It's. A brand new phone I just don't want to take any unnecessary risks. But also of course want to be able to get full service. Don't want to have to sell it off to get another one or anything.
Thanks again.
You do not have to worry about Root or Bootloader unlock when flashing the EU-Oreo, it should be safe. I have my doubts with 4G on T-Mobile's bands though, read this thread first: https://forum.xda-developers.com/lg-v30/help/lg-v30-unlocked-h930ds-doesnt-t-mobile-t3734810
One should note though that all comments were made prior to the possibility of flashing the EU-Oreo. I cannot test it with a T-Mobile SIM anymore (last post in this thread is from me) but my AT&T SIM gives me more 4G bands than it used to.
Ok I'm still waiting to receive the phone to test it myself. Obviously going to check it out stock first. According to the frequency check site it supports 2/5 bands for T-Mobile and metropcs. But doesn't support the protocol supposedly. I guess I'll see. I have both at&-t and T-Mobile Sims to test.

The frequency check site has been wrong before. I am not talking specifically about this situation. I've not investigated the H930DS and T-mobile, but in another thread about another V30 it was like they didn't even know the LTE bands AT&T currently uses. Seemed outdated information like, 4 years out of date.
Ok i got the phone today and only getting edge connection.
The phone i received is the india version h930ds. Will this make any difference when flashing the eu oreo firmware?
Also for flashing i am assuming i just need to download the eu open market firmware put the phone into download mode and load lgup via uppercut?
One other question does it matter if my phone is fully updated or not with the current india firmware?
Thanks.
Going to take me several hours to download on my internet connection so just waiting on it to finish now and trying to get as much information as possible in the meantime.

No, it doesn't matter which DS variant you are flashing from.
No, you don't need current India firmware since you'll be switching to Europe KDZ.
See the Euro KDZ thread for instructions.
Im sorry i don't see any flashing instructions. Just an outline of different methods such as uppercut or using model specific files or development lgup. Dont mean to be a pain just want to verify im doing everything right before i try. I did something like this on my g6 as well and the procedure was.
Put the into download mode
Launch lgup using uppercut
Select the kdz to flash
Not sure on this whether to set it to upgrade or refurbish? I think refurbish just wipes all user data like a factory reset?
Thanks.

Most people used upgrade. Try that first.
You can always reflash with refurbish if you don't like the result.

Ok thanks for the information. Its a brand new phone so i don't want to take the chance of doing something wrong but at the same time i have 12months of prepaid 4g LTE service that i would like to fully utilize.
Yeah ok. Finally finished and flashed this morning. Made absolutely no difference and actually broke dual sim support for me.
Do i have any other options?
