LG E975 - No LTE Option

Hello Everyone,
Hopefully this issue can be solved, as I'm using stock Android JB 4.1.2 (E97510h-EUR-XX) on my device and there is no LTE option in:
- System Settings> More...> Mobile Networks> Network Mode
Now, I believe it can be enabled by making a change to persist.radio.lteon as found here:
- https://community.vodafone.ie/t5/Network/Supported-4G-Phones/td-p/137830/page/1
However, it requires root access and as far as I'm aware, there is no root exploit for E97510h-EUR-XX at this time:
- http://forum.xda-developers.com/showthread.php?t=2249033&page=2
- http://forum.xda-developers.com/showthread.php?t=2163814&page=5
Here are my questions:
1. Is there any method to replace or edit persist.radio.lteon without rooting my device?
2. If 1 is not an option, is there any method to successfully root my device?
3. If 2 is possible, can I unroot and will this process be undetectable?
Any help is much appreciated :good:

My device was bought Sim Free from a UK company, just last year in fact and I'm not bothered if it was officially released there or not, as I have this epic mobile
Now, lets focus on the software issue, can anyone please answer my questions or suggest a better solution?

He hasn't bought a Korean Optimus G, but an E975. But for some reason if you put a SIM card from one carrier in the phone you cannot choose LTE, but if you put in a SIM from a different carrier you get the option to choose LTE. That's because LG has had the brilliant idea to block LTE for some carriers on an LTE enabled phone.
You can try contacting LG so they release an update so that LTE will be enabled for your carrier, but it would be faster to root your phone and adjust the build.prop like you said in the first post.

doesnt matter where mobile is form .. dont u see i bought from korea and europe soft was working but no lte so why he cant put korean onto european ?!?!?! it will still work + with lte enabled ..
contact lg god .. it is not down to them how do u want contact them and yeah they will tell you omg we are sooo sooryy we will correct it for you .. fkin pathetic .. they will crap on u .. man
lg doesn't block nobody .. the carrier needs send u setting .. dont u remember when 3g came up they been sending settings over SMS ? APN settings and MMS settings ? nowdays it is up to carrier send update over network NOT via sms .. and those carriers who has settings ready then 4g doesnt work ..

Why bother putting Korean software on your European phone and risk having a bad experience (due to the fact that Korean software is guess what optimized for Korean carriers)? When you can just root your device and change the build .prop which is less trouble and less risky to perform than to put a Korean software on it.
But to answer the question of the TS. You can root the E975 10 H firmware. I used Framaroot, and it works fine. You can read all about in the thread FAQ (Freaking Annoying Questions) in the Q and A section.

risky ? how can be risky .. so people here happily flashing third party roms and that's alright and when try to use original official rom then is risky ????! man are you OK?
optimized for their carriers ? no .. only APPS are included .. and those apps can be easily ignored ..
i think that your buildprop editing is risky .. ordinary people wont be messing with customizing files
wait for carrier till end of march then
I dont need to read nothing for me all working am enjoying LTE(4G) u dont it is your problem what u do ..
do what u want ..

Chill out dude. I'm only trying to help the TS out. He didn't ask anything about flashing a ROM, only to solve his problem with or without root.
Flashing any custom ROM is more risky than rooting a device. As it involves more steps then just rooting. So why make it hard for yourself?
Flashing a Korean ROM would mean flashing a KDZ file (that's the way I changed the E975 10 H back to E975 10 D) and that process probably changes the baseband of your phone(which is not the right one for the E975), so it could definitely influence the experience and battery life, etc.
You say that ordinary people won't mess with the build.prop file but they won't have any problem with flashing a Korean ROM?
BTW: There is no need in quoting the very last post everytime you make a comment, as it is clear what you're replying on.

That quote button has reason to be there .. that is why am using it ... And people know which answer belongs to particular person ..
for me is easy flash kdz ... and then obviously u need to flash modem back .. that is not hard too ..
And u are right in only one thing .. yes when people changing roms flashing then phone drains battery .. yes when I converted to E975 my F180S battery was very very bad .. I flashed original korean back and battery is much much better .
Like I said you can try korean if no leave it and wait for carrier to sort it out .. but they have time tho

No one here recommends to flash korean kdz in international versions nd vice versa too... Try some othr rooting methods nd try to change the build.prop.... Have yu tried moto chopper root method...??
Edit: looks lyk moto chopper method doesn't help yu... Yu cant yu downgrade ur software nd root it....

[Q] How To Flash The Australian Firmware?

Hey guys,
I am wondering if anyone knows how to get a hold of the Australian firmware and flash the 32GB/3GB AU Firmware onto my phone? I imported one from Taiwan but it's currently running the Taiwan firmware. Not sure if there's any difference between the two but I'd feel better if my phone was running an actual Australian firmware that I can update properly, rather than an international firmware that I've had to make look like it's Australian, I'm even a few versions behind for some reason, and sometimes when I reboot it's back to Taiwanese...
My carrier is Telstra AU, I've got the 32GB/3GB Gold version. Not looking to root, running everything stock except the launcher (Using Nova Launcher) and all seems fine. I've installed LG PC Suite, I'm really just looking to backup my current firmware/kdz and flash a new Australian one.
Thanks in advance guys, looking forward to being a part of this epic community!

Hey mate! What's your model number? Is it the D855? It's funny, I imported mine simply because I didn't want the Ausy version of the phone. The only changes from the D855 and the Ausy version (model number which is D855K) is a few reception changes, and I'm not sure if they are hardware or software. I did a quick google, and I found this link, but I'm not sure how trustworthy it is, I'd be wary and scan anything with virus protection before. But here ya go. http://poweredw.gaodi.net/forum.php?mod=viewthread&tid=667560
There isn't much for us Ausys out there, which is why if you want to have a bit of support from XDA and other places, best stick with the inernational version.
Have a good one mate.

Hey mate,
Yeah, it's the D855, imported from Taiwan. The link you sent me to is a 16GB/2GB ROM, those of which are apparently everywhere, but I can't for the life of me find a 32GB/3GB ROM for us Aussies. I did import the D855 because it's the international one, which should be modded and tinkered with by more people because it's international, rather than just the D855k which only works for us Aussies.
But yeah, if you find a 32GB/3GB ROM for Telstra somewhere, would be MUCH appreciated, sick of my phone going back to Taiwanese every reboot
Thanks man!

LG didnt release the 32GB version in Australia, so you will never find a Telstra firmware for it... or Optus or Voda for that matter.
It shouldnt make any difference anyway as long as it has the same LTE bands, which I think it does.
Try an EU firmware that defaults to English maybe?

i cant honestly tell whether they are 16GB or 32GB, since some of them dont specify. As far as I am aware, if you update to an old UK or EU version (like 10A) you will get an OTA update to 10E pretty soon afterwards.
if you arent sure which one to flash, theres probably someone that is worried about the same thing in the comments of the thread somewhere that had their question answered. i havent read through the whole thing yet so sorry cant help you there.

well its a personal web hosting... hosting sites always change for whatever reason. i would get it now while its there, cos who knows whether it will be there tomorrow. dont know whether the owner will keep it up to date regularly, but you can always read the forums to see when new updates come out.
the unbranded EU firmware is a popular one and will probably be one of the most frequently updated, so once you are on that you can probably get the OTAs as they come out too.

[Q] lg g3 model number question

Hi everyone , sorry to bother with this totally noob question but i want to be sure about one thing , my lg g3 model number so that i can find the right roms and root guide. I bought my phone unlocked in taiwan , i was wondering if someone could tell me what i would use as my model number when searching for compatible custom roms. From what i understand i should use 10m but i wana be sure before i attempt to root. I have included an screenshot of my device info. Thanks in advance for time guys

First of all, 10m is your software version, not model number. The 10m just means you are on firmware version 10m. Seeing as you bought your phone in Taiwan, you most likely have an Asian variant such as the F400 or F400k. You may possibly have an international D855, but it's impossible to tell from your picture. Take your battery cover off and let me know what model number you see on the sticker under the battery. The same model number should be plastered all along the inside edges of the phone once the battery cover is removed as well. Like I said, it should be F400, F400k, D855, or something similar. Please let me know.

Thanks for your help. I looked behind the cover and its a D855. So when i search for compatible roms and stuff i should look for that model numer? Thanks for patience with ny ignorance man lol

Ok so thanks again for ur quick help. Ive done alot more reading now and im ready to root my phone, one thing ive had trouble finding is the stock firmware for my device if anything should go wrong or if i want to dl the OTA lollypop update i just received in the future. My current firmware is v10m-TWN-xx and i havr d855 16gb, i could only find the 32gb version. Would really appreciate it if someone lets me know where i could get the 16gb. Thanks guys!

I don't think that they have started really pushing out Marshmallow yet, but there are some leaked builds floating around. Check this thread out: http://forum.xda-developers.com/showthread.php?t=3249803 Someone can probably help you in that thread. I have Verizon so I'm unable to flash any of those builds, so I don't know much about the process. I do believe you have to have root though (may be wrong).
It also depends on what version of the G4 that you have. What carrier are you on?

Download LG bridge and install it. Plug in the phone and click on software update. I'm in UK with h815 also and there was an update for marshmallow in there, although for various reasons I downgraded again to lollipop. When I checked again to see if the update was there, it wasn't. So do keep checking. Hope it helps

Im in UK as well. Is your G4 factory Unlocked or on a carrier. So far as I know, of the carriers only Vodaphone UK have started rolling MM out... but the likes of EE, 3, O2.. Virgin.. will probably come after xmas now. Im on EE myself and i dont hold any hope seeing MM till early January.
Goto "Settings" > "General" tab > "About Phone" > "Software Info."... if the software version is: v10J-EUR-XX, then its factory unlocked and you could get MM any time now.
Hope that helps

you will need to wait until it comes to your door step.

Yes that is lollipop. It depends on what carrier you're on, which appears to be O2, and it doesn't look like it's getting it yet.
