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....

This makes sense and I've already contacted LG, they have been useless so far, so will see what they come up with next

[Q&A] [GUIDE] D857 to D858HK - G3 Dual SIM with Google Apps!

Q&A for [GUIDE] D857 to D858HK - G3 Dual SIM with Google Apps!
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:

I was not able to edit buld.prop
Can change D857 to D858, but Build Prop Editor won't allow me to add HK at the end. Don't know why Please somebody advise.

OK, was finally able to change it to D858HK using Build Prop Editor from joeykrim, found it on play store and had to buy it.

D858HK
I am interested to buy D858HK especially when you mentioned it supports Google Apps, but there are two questions, I hope to find its answers.
Does the official system of D858HK support the Arabic language ??
Is it possible to receive calls from SIM2 if the data connection is active with SIM1 ??
Thanks

Hi ! Yes It's support arabic language and you can receive calls from sim2 when the data connection is active.

Hello! I also just got the D857 and didnt know that this will not have googleplay. If i root it and change to D858HK, then LG updates D858 units to Lolippop, will my phone get updated to Lollipop too?

Also, will it affect the TD-LTE signal for it's 4g connection?
This thing doesnt even have an option to change fonts even after downloading some from LG store. I guess it will be fixed when it gets rooted?

[LG-H81220U] I want to downgrade from MM to LP so that I can root my LG G4 (H81220U)

Hello, I want to downgrade my LG G4 (Software Version: H81220U) from Marshmallow to Lollipop so that I can root my phone. Could anybody guide me to achieve a downgrade AND a root? My carrier is Telus/Koodo in case it's relevant information.
Thank you in advance

first you need to nkow if tou can as in some models antirollback changes and makes it imposible to downgrade. so first make sure that antirollback versions they are if the same then you may if different then youll hard brick phone.

Hi @syphlect
Did you manage to downgrade it?
Have searched all the forums, did not find a way to root the LG G4 H1220u Koodo version.
let me know if you found any links

Use ...
Use ... LGUP - NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to downgrade from MM to LP. You want H81210 for your Lollipop KDZ. Once you've done that, you can install a pre-rooted image (easier) or root your own extracted KDZ. Note: You will not be able to obtain root through any of the Root-Apps - check out the link in the next paragraph for the general how-to for the H812, if you have not already done so.
Refer to [Canadian Guide] - Complete Source for the LG G4 H812. Linux VM/Root/Tools&Files at: https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449 for the how-to on rooting the H812.
Follow the Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks (https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586) ONLY for installing the rooted image and use the command for the H812 model in the 2nd post here: https://forum.xda-developers.com/g4/...ot-lg-t3164765 found in the following box: Command to Flash System.img (All Variants):
Once done, because you still will have a locked bootloader, you will not be able to install a regular version of a custom recovery or flash a custom rom (that may come eventually when efidroid is managed to be ported to the locked LG4's). However, you will be able to install a non-regular version of a custom recovery with TWRP-in-FisH that has been tested on the H812 and is working just fine with Version 3 Beta 4 and 5 (you can find those links in the later posts in that site): [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048

Yeah could not find specific to koodo Canada. Need to see if its safe to go with something similar to it.
Also I see my current software version is H81220Z. It got updated overnight even though I un-checked to install updates automatically.
Will the LGUP process still work to downgrade?

Koodo is on the ... Telus network. You can use Telus KDZ's (doesn't specifically have to be H81210Z and they seem to be available (check the Canadian Guide) - others have indicated you can use other Canadian providers (read the Canadian guide). I can't confirm this personally.
Use LGUP-NEW for sure as you are less likely to brick from what I understand if an anti-rollback provision has been put in on the latest firmware upgrade.

Read through everything carefully. You'll find everything you need if not in the OP, in the member posts. You cannot upgrade to MM and keep root and you cannot install any custom rom at this stage as the H812 has a locked bootloader that cannot be officially unlocked.
With steadfasterX's TWRP-in-FisH (https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048) you can install a customized version of TWRP recovery that will allow you to back up your complete phone.

You will find most of ... the questions you are asking in the Canadian Guide I provided the link to. Try the search function for the site posts
You are looking for an H81210 for Lollipop. I would suggest H81210N or higher for your rooted image as it has the latest Stagefright vulnerability security update. You can however use for your stock Lollipop image a lower version, e.g. H81210H before flashing your rooted image. The only caveat is that you may want to use Rogers/Fido firmware if that is your carrier, otherwise you will lose voLTE.
Again, I suggest you read through the posts, search for answers in the Canadian Guide. It's all been covered there.
Addendum: Koodo is on the Telus network.

Any rom that support Android 10
And please provide a proper guide how to cross flash..
I tried to cross flash many way but ends up with some error!!

Yes u can crossflash sprint to korean open. Do u just want android 10? Or is it important that the phone also works (as a phone)? So you need a rom that supports the bands in Bangladesh right?
There are numerous roms available that are android 10, korean open, ebw, and vzw, maybe others.
The guide to follow is in the guides forum. If u have trouble, it's best to ask in that specific thread, for crossflashing.
And btw, although your question concerns roms, this forum is for **Development** of roms, not general questions about stock roms. This question has nothing to do with development.
