[Q] Use E975EU in LTE Only mode

Hi.
I have E97510b EU version.
Sometimes i need to use this phone in LTE only mode.
In hidden menu ( 3845#*975# ) i cant select LTE-Options because give me error "not supported"/
Have you any ideas how i can change LTEonly on this phone?

The EU 10b doesn't support LTE.

Why not support?
when in the phone LTE simcard (russian yota) in setting i can change mobile network to Auto LTE\WCDMA\GSM mode.
but now I'm in italy and i doesent have lte sim card, and at this point there is no LTE network. i cant test it
its original LG site lg.com/it/telefoni-cellulari/lg-Optimus-G E975 support (800/900/1800/2100/2600 MHz) LTE bands.

It's just the firmware. Not the phone.

AW: [Q] Use E975EU in LTE Only mode
germany too. LTE is working

Are you guys sure you are running the EU Open 10b? Or 10b specific to your country? There are many 10b versions out there but only 1 EU Open 10b.
Cause I flashed the EU 10b and so did a few others and there is no LTE option in settings or service menu.

Very sure, this is a Swedish one which doesn't have specific version. When I got it it was 10a, but I upgraded to 10b with the support tool, which says Europe open. I also soft bricked it and flashed Europe open kdz. If you check the pic I attached you see I have 4g and world open. When you flashed eu 10b did you try backup radio, apn and maybe efs?

Interesting. My issue was that LTE wasn't available in settings period even with the correct modem. And service menu wouldn't enable it either.
Did Shellnutt get you unlocked successfully?
If so can you make a custom rom backup in cwm?

You got a PM.

E975 from germany uses 10B open EU too.
there is no specific german version available.
LTE can be enabled at mobile options and connects when if available

Thanks. I flashed it but no LTE in settings or service menu. So maybe it has to be something else. I even edited all the appropriate build.prop entries.
I suspect it's their modem.
Weird why it's only that way with the EU rom. I've been on Australian for 3 weeks now and no issues with LTE. Same with HK.

Hi how did you get around this and enabling 4g , I'm on optus Australia and cannot get 4g back where it was avalible on HK ROM, after flash to europe open its gone from all settings. When I try to enable try *#*#4636#*#* I get this app is not supported.
Thanx

Actually on the EU roms, it had to do with region in build.prop.
I don't quite remember which but basically you have to change it from EU or GB to AU or whatever the correct abbreviations for your country is. See if you can find my posts regarding it somewhere.
It's been a while since I ran an EU rom.
But once you correct the region and reboot, you will automatically get LTE as an option.

Which ROM are you on now?
Would Australian e975k ROM work on e975 open model?
Sent from my Nexus 7 using XDA Premium 4 mobile app

I'm on the Vivo E977 Brazilian rom.
I have used the E975k rom as well it worked fine for me.
Just make sure to backup your original modem from stock rom so you can reflash on the new rom if it's meant for a different region so that your LTE bands are covered.

thank you for reply. so you used Australian version kdz?
mines from HK and i didn't back up modem before flashing but i can always go back and download stock kdz via imei.
been thinking of flashing e975kkdz as this will be closest best for my region , but Europe open 10d is working fine tho.
i removed my sim and started phone and lte option was back on so i believe its got to do with sim/network to enable it.

It's the build.prop. I didn't have LTE in the EU rom either till I changed the region to non EU.
I don't remember which line it is but anywhere you see EU, change it to AU or AUS or whatever region you are in. However if you use the wrong abbreviation, the phone will boot loop so make a nandroid backup first.
And yes I used KDZs for all the ones I flashed and then houstonn helped me sort out the camera and wifi issue after unlocking the bootloader.
And if you find lines in the build.prop that has a carrier name, change it to your carrier name as well.

do you guys get a 4G symbol or LTE symbol?

Depending on rom. If I run my stock Canadian rom it is an LTE symbol. If it is an EU or other rom, it is 4g.
On Canadian rom, 4G is just HSPA±

Why you people buy korean phones?it's stated very clear,E975 is the international version,F180 is the koren model. You could try to flash an e975 stock rom on it...but it may be possible to break lte connection.

Well I have flashed E975 10C rom. now the phone works ok. (so far not rooted the phone). But I feel the signal strength is little bit lesser.

Regards
Sunil

Hi! I just happen to update my LGOG F180K to E975 using KDZ updater. If you do this, you must also flash the baseband for it. But problem is, as for me, the message sending is a headache. You can try at your own risk.

Well Thanks for the thread.
Everybody says update KDZ and also must then Flash Baseband. Noone gives the procedure to flash kdz then flash baseband.
My original model is F180L20S.
I have tried to root the phone but i couldnt do so yet.
I am back to F180L20S from e975 coz when in e975 there was no signal and everytime it shows network type unknown.
Luckily i manged to put back f180l20s u+ LTE put the language to english and managing. now its working. my mobile network setup shows 3g/4g data only not the conventional gsm/wcdma/lte etc.
will i get 4G network.
Thanks

If I change it to E975 it will change to different band? because f180 just support something like 800 Mhz band but my carrier support higher from that.
so my question is. if i change my firmware to e975 it will change my network band?
Another question i want to change my f180L 20t is it safe to downgrade to e975 10d?
thanks for any help for me.

Because, I think, that's all we know about the variants. You should consult your carrier and network provider about the issue.

O sign on the back is F180K, ULte sign on the back is F180L and 4GLTE sign on the back is F180S, why did you flash the baseband?

It's possible that your phone is using the IMEI from a F180L.

i think of it too. i know that olleh is f180k and my phone is from olleh so that means my phone is f180k, what makes me wonder is f180k baseband is not working on me, only f180l baseband works

If your phone is using a f180l IMEI then only f180l bsb will work.
