[Q] Flash Bell's D803 Firmware on Videotron's D801? - G2 Q&A, Help & Troubleshooting

Hey there,
I know both phones are exactly the same and that Videotron's D801 phone is indeed a mislabeled D803 and that it's compatible with almost everything from D803.
But I saw someone who flashed a Telus D803 on his Wind D801 phone and got problem with it.( See here, Post 23 )
My goal is mainly to see if LTE should work without problem and faster than the speeds I'm actually getting(that are more of a HSPA+ 42Mbps network) and also to see what are the build.prop values in this Bell's official firmware!
What should I do to proceed without problem and to make sure I can go back if something's going wrong? The guy in that thread seems to be knowing enough about flashing and it seems like he wasn't able to do anything else than bringing it to repair for them to flash it back to stock?
And about the regional code he's talking about, is it something in the build.prop thing? How do I do
In the ROM(CloudyG3) I'm currently using, build.prop network things are currently as follow:
ro.product.name=g3_global_com
ro.build.target_operator=GLOBAL
ro.build.target_country=COM
I'm guessing I should put it to the following or maybe something isn't good? I don't even know how to backup build.prop!:
ro.product.name=g2_vmc_ca
ro.build.target_operator=VMC
ro.build.target_country=CA
I'm using Virgin Mobile(Bell network)

[REQUEST] TMO EFS Backup

Hi all,
I have a Rogers LG G2 D803. I'm trying to enable AWS bands, and to do this I'd like to attempt to restore a TMO EFS backup. I'm doing this because I want my Rogers phone to work on WIND.
If it works, it means we might be able to enable bands that devices aren't supposed to support, like switching between TMO and AT&T bands, or even unlocking them all! But to test if this might work I need a TMO EFS to restore, as just flashing the TMO modem locks down my radio.
Just PM me if you're willing to share one, thanks!

EFS is a Samsung term, not an LG or universal term. What you want is a .QCN (QPST) backup with the IMEI stripped out. I've done this mod on my AT&T S4 and Note 2, so I know where you got the idea from.

Thanks for the encouragement. As it happened, I did use the EFS backup in TWRP and restored a TMO EFS. It didn't work - My phone kind of just refused to cooperate. I have a feeling that between the D801 and D803, there are some hardware incompatibilities. Until a real dev gets this phone and plays with band settings, we won't see this stuff happening.
In any case, I returned my Rogers G2 and ordered a T-Mobile one off eBay today.

[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
Get european d802220 d or f for 32 gb version have look on second tread in lg g2 general, follow instruction its very very easy, just backup everything you got away from phone, as you will loose everything

[Q] Can I flash Tmo Stock Image on AT&T Model?

Just ordered my wife a G2, it is unlocked however it is the AT&T variant and we are on Tmo. I have read that someone took a Tmo rom and made it possible to flash this to the AT&T model along with the KK baseband so that we can use Tmos wifi calling. However I would like to know if I can simply just flash a Tmo stock image and flash the KK baseband if this will work or am I looking into this all wrong?
This is where I read about the Tmo on AT&T rom:
http://phoneprouser.com/lg-g2-rom-that-supports-wifi-calling-on-att/1007/
Can anyone tell me if the ROM mentioned in the link above is this the latest ROM for the G2? Thank you in advance.
Side Question, if I want to flash Cyanogenmod and still want to retain the wifi calling can I flash the Tmo rom along with the aforementioned KK baseband?

THIS IS AN ABSOLUTE AND COMPLETE NO GO, FLASHING A FACTORY IMAGE FOR A DIFFERENT MODEL CAN HARD BRICK YOUR DEVICE, IN FACT I'D PRETTY MUCH GUARANTEE IT!!! GO INTO THE ATT DEVELOPMENT THREAD AND FIND SAID T MOBILE ROM FOR YOUR DEVICE, FLASH THAT IF YOU WANT TO. As an answer to the side question there is no way to retain wifi calling on cyanogenmod, especially on a non tmo device. Finally as for the baseband find out what baseband the respective ROMs need (the tmobile one for ATT G2s or the CM build you choose to use).

Verizon Galaxy S5 no service with tmobile or metro

Before I rooted my verizon galaxy s5 I was able to use ATT sim cards but the phone would not get any service whatsoever with a tmobile sim or metro pcs sim. Everyone i spoke to at least was able to connect to the tmobile or metro pcs network, even if they were having data issues...but I was not even able to get a network signal. Finally, I rooted the phone and am using a tmobile rom thinking that may help. But no luck. For some reason my phone will not register itself on tmobile or metro pcs, Not even to just connecto to the network to make phone calls. I tried 2 different tomible roms and i think an att rom and no luck whatsoever. Anybody else experience this issue? Is there a root function or service menu that I need to access to enable the proper band? Is rooting the phone even going to change anything? Makes no sense how every other verizon s5 out there has no problem connecting to tmobile or metro but I have the only one. Ive scoured the forums and have yet to find any answer....thoughts? Oh, I also tried every APN settings combination imaginable. Even other carriers just because I was getting nowhere with the tmobile and metro APNs.
Quite a lot of your thread made absolutely no sense, so I'm not sure if this will help.
Look for a tar.md5 that contains the stock modem partition for the Verizon S5, and flash it through Odin.
Are you bootloader unlocked? I would just flash a generic klte rom, like Cyanogenmod, instead of flashing an ATT or T-Mobile rom.

According to a few people i spoke with the root for verizon s5 can only accept TW roms. And to clear up anything that doesnt make sense. my verizon s5 will not get any service with tmobile or metro. Works fine with att. So i decided to root. After rooting still no luck. However, before I rooted I was getting no bars at all. After rooting I was actually getting service bars but still would not get any actual service. I tried every APN setting I could find and still no luck. Thats all. I will try your advice as far as flashing the tar.md5 and let you know.

There was a bootloader unlock exploit released - it allows any rom to be flashed. It's been in the top development posts for weeks. Go check that out, and you can flash cyanogenmod.
I actually am in a similiar situation except I am already on CM13 using a previously Verizon S5, I just started Tmobile service yesterday and in general I can make calls but data is rather inconsistent. Example right now when I make it call it falls down to 3g (Normal) but when I disconnect it tries to connect to H+ then 3G but all of them don't supply it data so it just swaps around 3G LTE and H+ and I have to airplane mode on/off to fix it. So this person may still have issues using CM13. I did already go over the APN information with people from TMobile and from post around the web. Does anyone think that flashing the Tmobile s5 modem stuff will fix this?
you just need to get the correct APN settings

I've tried the correct son settings. It didn't work. I used the settings found online for T-Mobile. I called T-Mobile. Non of the settings worked. I flashed back the the stock rom. No joy. flashed a verizon s5 rom again. No joy. I am starting to think that this is the only verizon s5 that won't allow t to register on T-Mobile's network.

How to unlock network bands on Verizon unlock phone ?

Hello everyone so this my history I'm on T-Mobile Network and I have a Verizon v20 unlock phone everything working good just the internet is slowly so I searched about how to enable bands (I can't find something clear ) on Verizon v20 to make it work on TMobile (full LTE ) its this possible ? Is there some mode or something the really work (Unlock bands) like I said already searched but I can't find something really clear
Note : I have just H sign allway on like other user experiment jus show 4g lte for a minute
Thanks on advance
If I understand you correctly, perhaps you need to set up an APN for T-Mobile. It'll be under Settings->Networks->More->Mobile Networks->AccessPoint Names.

Well I already have the TMobile APN and I trying to figure how to get lte because I have only H icon and no Lte (speed) so what the asking is if is possible activide TMobile band like 7 , 12 etc ... Thanks for your reply ?
Well, you came from Verizon CDMA and T-Mobile is GSM. As long as you've got the proper values in the T-Mobile APN (and you got your sim from T-Mobile), I'm not aware of anything else you can do. Could be wrong, though.
Good Luck!

Thanks I'll keeping searching if I find something I'll post here but if someone have a information about how to making work (unlock frequency's band ) more than welcome ?
The ONLY way I could is to flash another carrier or us996 custom rom. The vs995 rom apparently forces the phone to connect to Verizon towers and bands only. Can't edit in any secret menus, nothing, that's the only way I could. Tip, if you want to use wifi calling, flash a custom stock TMobile room not us996
Interesting so there is a way to flash us996 (Spring correct ?) rom on V995 ? Anyone know what's the safe way if is possible ? ?

Flashing a tmobile rom on a nontmobile phone is a great way to brick. Best case it won't boot and lets you flash back, though it could trip ARB as well making it impossible to roll back. The kernel uses a different security key than the other models.
Has anyone tried flashing a Non.Hlos.Bin from which-ever carrier you are wanting to use?
I don't own this phone, I just by chance took a look at this thread.
Yes of course you would need the correct APN. But you may also may need to flash the modem file from the carrier you are wanting to use. ( It can be extracted)
Another option is using QPST.
With QPST you can change the IMEI, add bands, repair a bricked phone, flash a rom etc. These are just suggestions for things to try. Again, I do not have this phone.
Old thread I know, but if you or others have this problem, have you tried using the LG hidden menu (accessed using dial screen)?
*#546368#*996#
If you have the 996 version, just copy & paste. Otherwise, just change 996 to what model you have.
Field Test > Modem Settings > LTE Band Selection
Select the band you want to use/test, then wait a few seconds for it to register. Your signal will drop for a moment, then should show 4GLTE, if you selected the correct one. There may be more than one that works, but one may be more congested.
You should find a list of available bands for your carrier, before messing around.
Also, do not mess with other settings, or you could really screw up your phone I know from experience.
