Convert a H815T to UK (euro version)

Can you convert a H815T (Hong Kong) version to a UK (Euro) version using the correct files when rooting? So if I use the International H815 10c Version files will this change it to Euro verions?

What do you mean by Euro version? What do you want to change? I don't think you can do what you want by flashing a different system image.

I think he's looking for root? Same as myself.

I'm not so sure.
But if you have the H815 you can root using the international files posted in the root thread.

Too many versions if the 815. I don't believe the 815t is rootable yet.

Yes it is.

Yeah I was asking if the H815T you could you use the H815 files and you can.
I could get the H815T cheap but found a selling the H815 for the same price so I don't need this anymore. Only if LG could stop making a million different variants and confusing people
But thanks for all your help guys.

I bought the H815T because of band 40 support, which Optus uses.
I used the international H815 10c image to root mine.

Optus are shipping the H815T, Telstra are shipping H815K (which is missing quite a few bands compared to the T). I have one of the Optus H815Ts. Im not prepared to flash a slightly mis-matching system.img and would much prefer to make my own. Ive not let the firmware update yet, and the download mode shell works. But the recovery block device isnt present preventing TWRP from being flashed in.
I dont think 'converting' a H815T to a euro would help with the unlock at all, because I think the key is not a flag but a hash (unconfirmed, the hex key gen thing could be a bluff) and the hash is generated after LG lookup your device ID. Even if you changed to the euro firmware, I think LG would still consider your device a 'T'.

I have been looking for a root method for the T version but it dosent appear possible yet.

This is correct. Were going to be waiting a while for a bootloader unlock. Telstra/ Optus certianly wont release one so were relying on someone to claim the bounty and figure out an exploit.
Just FYI if your looking for ROOT you can use the Low Effort Root and flash a euro version, but you wont be able to unlock the bootloader.
Also if you just want Marshmallow on your Telstra or Optus phone you dont need to unlock the bootloader, you can simply run LGUP and flash the 20b files to it. (you cant have Marshmallow and root as far as I'm aware)
Anyone in this thread have h815k original system.img file? or a rooted system.img file? Reason is I flashed the 10c version for root but now I want to run LGUP so I need to reflash to stock and I didnt backup (silly me).
Let me know thanks guys

So is it dangerous to go from 815K to 815T as radio bands are different? i changed from Telstra to Optus so wondering if I can do this...

I have the H815, it says the network code is "SEA"?

Okay so I want to root my phone but I checked on imeidata what H815 variant it was and under Network Code it says SEA. So what exactly is that? I googled it but it didn't really come up with anything related to the phone.
Also, is this variant even rootable? I hope so, I want the cool stuff. D:
It also says SW Version : H81510B_00, carrier says ARROW. If any of this is relevant I have no clue.

you are using the SEA version of the H815. It's identical to the European counterpart, but basically still considered a "variant".
You can apply most of hack/root/exploits that can be applied to the H815, only that you can't unlock the boot loader, and thus can't install TWRP on it.

So just to be sure if I follow the "Low Effort Root" for the G4 on this site, it should work properly correct? I downloaded the files that said it was for the International Version.

yeah, as long as you use H815 files (not h815T, or H815P) then it should work.
case in point I flashed 10D open EU on my h815 SEA, no problem.
Though actually the easiest way for you to make sure your stuffs work is to flash a stock EU rom on it, then flash the rooted IMG for that EU rom on top.

SEA stands for Singapore version

Bought G4 - have couple of questions

Hi,
1. Is there any option (and guide) how to change stock firmware branded to stock firmware unbranded? And don't loose warranty if I want to repair phone?
2. Why G4 have so small community? This phone is great. Isn't it?

Depends on your model. I think you can just flash an unbranded kdz, if you're on H815 International.
Just use LGUP, download the proper kdz and select "refurbish", when installing via LGUP (note: this will wipe your data and system).
Official LGUP thread
20D kdz from @autoprime
Please note that this kdz is only for H815 - you can check device model under settings --> hardware information
EDIT: You don't have to be rooted or bootloader unlocked to use LGUP - So this won't affect warranty

G4 shows wrong version

long time lurker here.I bought a g4 second hand.it was advertised as h815 unlocked.the imei checked out online and all stickers said 815 as well.but in hardware info it showed h815T(HK variant).thankfully i knew how to flash firmwares so i downloaded a KDZ and flashed it with lg ft 2014.for some reason (i dont remember why) i flashed 2-3 times with other kdzs and ended up in the current state.the phone now shows H818(dual sim variant) in hardware info and doesnt
detect my sim card(same sim works fine in my G2).I never downloaded the h818 kdz.
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||((TLDR))||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
phone shows wrong model in settings and doesnt detect sim card.flashing stock kdz doesnt fix this
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
any help would be appreciated as i have been flashing various KDZs since the last 2 months but have had no luck yet.
ps.
i am able to root using system.img injection method if root is required

i think is was misinterpreted. its a h815 but a h815t indeed and unlocked mean carrier as you know theres no way to unlock bootloader.. you need to flash the h815T KDZ. i hope that you didnt mess your imei.
inject only works in LP not on MM. also youll need to find out if you can downgrade to lollipop. as this phone have antirollback wich means once you are on a version you cannot go nack or youll hard brick phone.

thank you for the response.im on lollipop right now since ft 2014 doesnt flash MM and lgup and ft 2.0.1.6 stop flashing after checking phone info(they stop flashing as phone shows h818 but kdz is for h815).I flashed h815T kdz multiple times(twice just today)but phone still shows h818 in lgup and in settings.the phone cant be h818 as it only has 1 sim slot.
imei is ok right now.SIM issue happened to be a ****ty sim cut job by the customer service guy.only remaining issue is the wrong version showing up in phone settings. cant flash MM due to that.
also,is there anything good about upgrading to MM???

Actually MM isnt an upgrade. Lollipop is best(maybe nougat will be worth anything). I think you should flash uk v20g kdz with lg up(or LG firware flash 2014). I suggest using LG UP also you can give TOT method a try

Do they check in build.prop? If so just change build.prop value and you're good to go. I think that there is also possibility to fake your software version and then flash anything you want
