Possible to Convert LS980 to D802 ?

Please HELP!!!
can you guys please tell me is it possible to convert Sprint LG G2 (LS980) to International version (D802) firmware?
looking foward for your help.
thank you!

Yes it is possible with lots of searching and hacking. It is way easier to do permanent SIM unlock procedure and easier than that, use a custom ROM. See link:
http://forum.xda-developers.com/showthread.php?t=2655133
Here's my knowledge from the conversion. I could follow the steps in that post but the phone never really worked right. The steps to make the phone work on GSM carriers caused menus to disappear from within the phone, such as ability to change APNs. It works but there's a better way.
I flashed an AOSP ROM to my phone. Shameless plug here for LiquidSmooth beta, I've had the least problems getting a working phone with that ROM, actually works out of the box. While on AOSP, I can replace my Sprint LTE SIM with that of another carrier, reboot the phone and then go to the *#*#4636#*#* menu and change radio mode to GSM. I'm using an AT&T SIM now, domestic even and can SMS, MMS and have HSPA+ data, no LTE. If for some silly reason I want to switch back to Sprint, just swap SIM card, reboot phone, change radio mode in the hidden menu. Simple.

Thank you very much mate :highfive: ! but actually what i want is to have D802 (Stock) firmware on LS980. because D802 is getting updates so quickly. ( Knock Code) i searched for a way to convert but i couldn't find it. can you guys please tell me is it even possible? because both devices are have same hardware except the LTE band! looking forward for your advice. thank you! :good:

I know it's possible. I read once what has to be done. There's some trickery that has to be done in the build.prop which makes the phone think it's another model which would allow the flash. All I can say is search. It is on the XDA forum. The term used was CID change. Found a ton in 2 minutes all related to HTC One on Google, finding the G2 should be easy enough with search.

Once time converted, the frequencies GSM 850/900/1800/1900, UMTS 850/900/1900/2100 (3G), LTE 800/900/1800/2100/2600 (4G) it work or not?

Please someone answer this last question .
Once converted, will the converted LS980 support the frequencies of D802 ( GSM 850/900/1800/1900, UMTS 850/900/1900/2100 (3G), LTE 800/900/1800/2100/2600 (4G)) instead of the LS980 frequencies ?

Simple answer is "No" . because frequencies are hardware things. we can only change softwares. LS980 will not have D802's frequencies by anyway.

Yes there is a way to do it but I don't know, me too I'm searching for this solution, because I bought a used LS980, and when I plugged it into PC the LG Support tool ask me if I want to upgrade the software of the phone (Into Lollipop) and the actual version at that time was D80230e, I let the authorized the LG Tool to download the update, and when finished, everything goes wrong the phone became unusable, when I push in a zone it react in another, and it was really hard to achieve the first steps of the configuration, when finished I decided to open the phone and look at the motherboard and bingo I found that it's an LS980, then I downloaded the LS980 firmware, I flashed it, and everything became OK, except the lost IMEI, then I tried to resotre the EFS backup that I done before that I upgrade it with LG Tool, and then the phone stay on the LG logo...Right now my phone is out of service, I use it as camera and nothing else...I'm searching for solution every time but I found anything...Is there any solution ?

What about changing motherboard only, will that work ?

On order to restore your IMEI you've just to flash your phone with the ZVD version and let the OTA updates install,then you'll recover your IMEI, but if you flash again with the ZVD you will lose it again

You're on nextel carrier branded ? Can you put this ota on 1097 from carrier ?

It's the same model xt1097, as far as I know the only diference between the stock ROM and the carrier's ROM is the internet settings and stuff. Nextel Doesn't push bloatware or such so I'm guessing they just load some settings and rebrand the sistem version. I'm on 21.27.3, maybe the baseband could bring some problems I don't know... but I'm pretty shure it will work. I've been flashing stuff in carrier models for a while know and besides internet settings I've never had more problems
If somebody knows me wrong please correct me

So, how do we flash this?

I think you only have to check your APN settings. If you have an US model just make shure you're flashing the proper zip for your model. Carriers just add apps and stuff nobody use.
Think of it as installing CyanogenMod, everyone around the world has installed it and yet there aint carrier versions. Everything is about the model, not the carrier.
Anyway, whatever you decide to do you're doing it at your own risk. I'm waiting a couple of days to hear from my carrier so I can't give any help until I do the proces my self.

[Q] No 4G/LTE in my LG G2 D802.

Hey guys,
As you can read in the tittle, my problem is that I don't have 4G/LTE I get 3G+/3G or HSPA+/HSPA.
Right I'm running Lollipop with the custom ROM, BlissPop with B14ckB1rd Kernel. I tried other ROMs (CM, RR, Paranoid) but I don't get 4G in neither of them.
I lost my 4G a quite ago, don't remember exactly how but I can imagine it was when I tried those early Lollipop builds, after that I went back to KitKat and the 4G was gone, even I tried going to full stock but neither that work.
I'm sure is a phone problem because I been with 2 different carriers and couldn't get 4G. The SIM card is brand new and today I spent around 2 hours talking with the Tech Support of my carrier checking everything is all right.
I also tried to change the Baseband/Modem/Radio (Right now I have Cloudyfa KK for the D802).
This might be also helpful for guess what could be the problem, when I dial *#*#4636#*#* go this phone information, down to prefer network type and select LTE only I lose service, by the way, in that configuration I have selected LTE/GSM/CDMA auto (PRL) and USA radio band.
I'm open for all kind of suggestions, If you need more information don't doubt in asking me.: fingers-crossed:

Well is good to know I'm not the only one.
Could you share more information?, like when and how it happened, so we can figure out what is wrong.
Today I'm going to try to get some logs, and check the system folder.

It happened to me with stock lollipop v30d vodafone ITA with another carrier sim (TIM). Solved after flashing v30a open ITA kdz.

I'm gonna try it, will send feedback as soon as possible.
Sent from my LG-D802 using xda Forum

No luck, I installed the V30a Italian version as you suggested but as you can in the screenshots no 4G at all, when I try to force LTE (This time with the command 3845#*802#) is lose service like in my last ROM, so I'm almost sure is hardware and not software.
Can some confirm me that, cause when you go back to stock by a kdz or how ever their is not residual imformation, every thing is fully clean right? Or some firmware just stay for ever?
If you guys have more suggestions that could try before I send it to somewhere for get it repair.

H990DS(TWN) - Upgrade/Refurbish to other Regional ROM version

Good day to all.
I recently bought a V20, a Taiwan version H990DS, so with a TWN ROM. The latest TWN ROM is from last year. Is it possible to flash to the newer Singapore ROM? (SEA)
Like this one : H990ds10e_00_OPEN_SG_DS_OP_0314.kdz (10 april 2017)
I now have :
BASEBAND : MPSS.TH.2.0.1.c3-00027-M8996FAAAANAZM-1.77269.3.79643.3
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10c-TWN-XX
MODEL NUMBER : LG-H990ds
I have experience with flasing rom's, but only at Samsung devices. LG is new for me. But I have read the threads around here how to flash a new ROM.
I hope somebody can give me a answer to my question. Thanks in advance!
Greetings from The Netherlands

Hello
someone actually managed to do it, so it seems doable, and fairly easy I'd say.
I was tempted to do it myself, and still am, but then I was just hoping LG would come around with a new update to avoid me all this nuisance...

Hi @buongu
It is just one person who switched his ROM, (@Mattfly93)
On Samsung devices, like the S7, it was a piece of cake switching ROM with ODIN. The risk was very minimal.
I wonder how high the risk is switching ROM with the LG V20 H990DS using LGUP.

there were others too, a guy here (https://forum.xda-developers.com/v20/help/australian-f-h990ds-t3551066) tried out different ROMs to find better suiting apn settings; other guys too, actually a lot of people with the H990DS seems to be into this subject

Are you going to change ROM version? And what is the reason to change it?
What are the differences between the Taiwan(TWN) and the newer Singapore(SEA) ROM?

Yes I'm definitely considering a change. Mainly because they keep receiving updates, I don't know the details, but it seems like there have been a few improvements in the audio compartment as well (which is what I care most about), practically every version had them expect for the h990ds twn. SEA seems to be the one getting updates on a regular basis, so that's the one I'm looking at
there shouldn't be any real difference, same apps, same sw release, just a few fixes ahead so hopefully less glitches.

I don't enjoy this kind of tweaking anymore
I used to, when updates were scarce and custom ROMs were pretty much the only way to prolong a smartphone's life... but nowadays companies promise a 2 year support for all their devices, so why do we still need to put up with boring and elaborate actions like this?
and there's a chance we won't see any future OTA either, judging from the info I have found it will still be recognized by your software as from TWN, but the update won't match any of the ones for TWN or the ones for SEA, so from that moment on manual updating is all you have... and THAT pisses me off

I can understand your feelings about this and to be honest, I share them. I am not afraid of switching ROM from TWN to SEA, i think that will go without any problem. But after that it is manual updating, that is something I did not realised. I have to think about this, but the chance I will manually update is big. The updated software and, most important, the security updates can not be ignored. We will keep in touch. Thanks for your opinion.

I would like to know if I can safely use the 'Refurbish' option in the LGUP tool for changing my TWN(Taiwan) Rom to SEA(Singapore) Rom?
Or do I have to use the 'Upgrade' option?

I am currently on the India ROM, which was last updated in January. Also seriously thinking of switching to the SEA ROM. My only concern is if VoLTE will work on it -- currently, I use a Jio 4G SIM. Does anyone know if SEA will support it?
I also have a S7 Edge, and when I changed ROMs on it (from India to UK ROM), VoLTE stopped working. I had to flash back the INS ROM to get it to work again. Does the same happen with LG ROMs? That is, are regional variants of LG ROMs unique?

I can only answer your first question: yes, the SEA firmware fully supports VoLTE

im also thinking about doing this. im on v10e ESA, securiry patch is December. where can i get the DLL for H990ds for LGUP?

All you need is in the 1st post of this thread. Good luck and let us know.
https://forum.xda-developers.com/v20/how-to/v20-kdz-restore-failing-9-completing-fix-t3546817

I took the plunge and it did not go off well! A few observations.
1] I was trying to switch from INS to SEA. Refurbish option did not work -- throws up errors when installation reaches 4 per cent.
2] Upgrade option went off without errors but I ended up with cust id mismatch error after reboot. I think Upgrade leaves a few files behind that are related to firmware region. However, you can dismiss these warnings and use the phone. I also ended up with device failed to decrypt error, but that was sorted with a factory reset.
3] VoLTE (from Jio in India) does not work on the SEA firmware.
4] The SEA firmware felt smoother and more responsive than INS one from January. I also see a few SG specific apps.
5] Have now restored back to the INS firmware by downloading the appropriate KDZ file.
6] Now hoping LG wakes up soon and ports the SEA update to other regions!
Thankfully, the LGUP tool is pretty reliable, and if you are used to ODIN, you will be at home here. I would suggest you go ahead and check it out. Maybe it will work for your region...

I just did the same from TWN to SEA, and surprisingly VoLTE is there!
I see it in the shortcuts, I have no use for it because neither of my carriers support it, but it's there

That's interesting. I did not have this option on SEA. I guess it is carrier specific. From my experience with Samsung S7 Edge, relevant carrier strings had to be present in the CSC file/ folder for VoLTE to work.
If root was available for our device, then perhaps this issue can be fixed.

For India, the latest update listed on that site is from April 1. But I don't see it in the downloads section. Does it take over a month for the firmware to be actually available?!

Does any of these dual sim firmware enable band 66?

Can't get service on any ROM - I think my modem is messed up?

Hey folks, thanks again for for all the work keeping this phone supported.
I just got my V20 and I'm trying to get it working with my UK SIM (O2, 4G) but since I did the Dirtysanta root I've not been able to get mobile service on any ROM, even return to stock or flashing the 915 KDZ. I stupidly didn't make a backup with LGUP!
Any ideas how I can restore service to the phone? I'm currently on unrooted H915 KDZ. Does anyone know of modem files etc I could use to try and get SIM service working again? I've seen a guy posting a 'universal modem' here but he didn't seem like a particularly knowledgeable user, and I've also seen a zip of the 'h910 oreo modem' but I'm reluctant to flash anything unless I'm sure.
Or could it be a physical fault with the phone (ie the SIM slot)? Is there a way of ruling that out?
Cheers for the help! My new phone has turned into a total nightmare and I could really use the support

PS: I opened up the phone to aply thermal paste, and the mainboard seems to be an F800L Is it possible the refurb seller was using F800L modem firmware with the stock Nougat AT&T ROM?

Not sure...but a do quick look in your mobile networks and make sure set to automatic. Seems dumb, but if not that can cause service issues.
