[Q] Rom flashing - G2 Q&A, Help & Troubleshooting

Hey ppl been looking into flashing roms and have seen you cannot flash a 16gb onto a 32gb phone. I was just wondering why?
I have recently bought an international lg g2 d802 which has no lte setting for three. Have since discovered after putting mrs's o2 sim in it and the setting appearing for lte auto, then disapearing when i put my three sim bk in so i think it's to do with the lg kitkat 4.4.2 rom having no 3 settings for lte in it so i will have to wait till three and lg get together. Prob never
I have found the hidden menu where you can switch it on but as soon as you reboot it reverts back.
Any way i have heard you can get the uk three 16gb rom from somewhere which should have these settings built in but have read you cannot flash this onto a 32gb phone??
Can anyone point me in the right direction please. Would me rooting and using a custom rom enable me to use 4g on three
Thanks again

Any body?

Porting stock L-01F (Japanese G2) ROM to d800 (AT&T G2)

I would like to know if it's possible to port the stock ROM of Japanese variant of the LG G2 (L-01F) to an AT&T LG G2?
I travel a LOT to Tokyo and using my phone on AT&T will just cost me an arm and 50 legs when I'm half across the world.
I'm thinking if I just flash the stock ROM of the Docomo version that it'll work, swap out my AT&T SIM card for a Docomo SIM card - flash the ROM and be good on the go. And when I go back to the states I'll just restore the nandroid of my AT&T stock ROM and slip in my AT&T card.
What exactly does it take to port the ROM over? I'm hearing that just flashing the ROM and flashing the AT&T kernel would work just fine.
Thanks for the help!
Bump, I really hope I've posted this in the right section.
I'm not a developer or anything, but wouldn't you need to unlock your phone for this?

Yes my phone is unlocked but some off the apps that are exclusive to Docomo handsets are locked and some are tied to their ROM framework and such. I tried downloading certain apps to see if I can get them to work on the AT&T ROM but it's a no go :\

[Q] Should I flash UK open ROM

I've just bought a LG G2 32GB from eBay (Hong Kong version D802) and the question is to ensure that I get 4G using my network provider that is 3UK.
Should I flash a UK open ROM on the phone even though the listing states that the phone supports 800/1800 4G bands which I believe are the ones that 3UK use?
Having looked at the revert to stock ROM thread there's only a 16GB UK open ROM available can I still flash this ROM or would there be issues?
Or should I just stick to the Hong Kong ROM that ships with the phone?
Thanks in advance
Stick to the rom that comes with the phone. On a side note, if you flash a 16gb rom, you will get a 16gb phone and its very hard to restore

Thank you for the very useful response. That's scary that if you flash a 16gb ROM the phone turns into a 16gb phone I don't want to be doing that.
Same issue.
Hello,
i Am newbie here, recently i brought a LG G2 D802 supposedly from a EU store and i am in Finland, but to my surprise the software firmware is Asia made, Hong Kong to be particular. it goes like this, D80210b-HKG-XX build JDQ39B kernel 3.4.0. With this original Stock software, the 4G option is not shown( i know it can be done by hidden menu but i want to get a permanent fix); the MMS setting althought i did it manually by inserting the values provided by the Network service provider.Still i am unable to get that fix.
I am in turn to contacting my seller for the correct working OPEN stock rom installed G2 but if the case does not go like that then i wish to root it to the OPEN international ROM . From what i have read, if you update then it goes back to the HKG rom, if there any way i can remove the factory rom with the OPEN Rom and receive the update OTA and it will not revert back. I have been doing my research on this but i am not able to get the answers... Hope some one will shine some light on this.
Thanks in Advance !!!

Hi,
Does your phone shows the 4G option in the network mode?? i have the same firmware and i do not have the 4g option in the network mode. Plus on the downside the MMS is also not working.

[Q] Can I install a T-Mobile stock ROM on a AT&T unlocked version

Hey guys I need help... I got my wife an unlocked AT&T LG G2. I set up the APN setting and the LTE was working but as soon as I don't have a strong signal the phone drops to gsm and it doesn't give me the options to include other frequencies on settings. I worked with T-Mobile to fix the issue but they don't have a fix. I was adviced to flash a T-Mobile stock ROM is this possible if the build model is different?

[Q] Issue with 4G on LG G2 Three Network D80220c-466-92?

Hi everyone,
I have tried to understand the cause of my issue with 4g. I bought LG G2 D802 32GB from eBay. It has the software version D80220c-466-92 on android 4.4.2 KitKat. I live in the United kingdom and am on the Three network. I do not have lte option in my phone settings, when selecting 4g in 4g area through secret menu it does not connect to the service although i should be getting 4G.
Does anyone know what i need to do? Do i need to flash something or root? I do not wish to root my device as i need to use the threeintouch app which does not work on rooted devices.
I've looked through this website but im confused, could i flash kdz or something, not sure which one id go for however.
Any help would be greatly appreciated guys and gals.
Many Thanks
Ham

Galaxy SM-A500M 4G does not work with new carrier

Hi all,
I own a SM-A500M phone. The phone has unlocked stock rom (original rom is not modified by carrier) and updated trough OTA to android 5.0.2. I know 4g does work in my phone because I could use it with my prior carrier, but I recently changed to CLARO and with this new provider I don't have 4g acces, only H+ and it is really slow and laggy connection.
I know the following:
1) Sim card is a compatible 4g nano sim
2) The carrier CLARO has 4g coverage where I live
3) The phone is not the problem
4) I have tried all the usual FAQS (APN's, select LTE in config, reboot) with no success.
5) The phone's variant is right (latinoamerican brand), so It can't be due to frequencies or bands problems.
I asked for help in CLARO and told me that this has happened amongst users with unlocked phones (that is, rom not modified with CLARO's bloatware), and the solution is to flash CLARO's rom. But the problem with this solution is that CLARO hasn't released android 5.0.2 update (and I think it will never update) and I really like android 5 and wouldn't want to return to 4.4.
So, is it true? Is there a chance to fix this problem with minor tweaks? What is the problem here?
Since I recently acquired this phone, I would prefer not lossing warranty, so rooting and custom roms might not be an option.
Thanks in advance. Kind regards!
You could try to flash their rom and check if it works. Then you can be 100% sure that hardware/chip/network provider are fine. I have the same phone on since last week, but still did not go to get the chip at a movistar office. Maybe you need to activate the chip and they refuse to do it unless you get their rom. Maybe just getting their rom, and then flashing back the updated stock one or a CM or whatev would be enough.
