[Q] D80220c - Canada - Mobile Data and LTE Selection

Hey everyone.
I bought my G2 from an online retailer. It's from Europe I believe (D80220C?).
Here's my issue:
When I try to activate LTE in my mobile data menu the only selection is "GSM / WCDMA Auto". Even further, when I install a custom ROM I get the selection for LTE but it does not enter the LTE network. And further again, when I enter the 3845#*802# menu and select "LTE only" from the 'Hidden Menu -> LTE-Only -> Modem Settings -> RAT Selection' menus, I lose my network connectivity completely.
I know my SIM card works because I have an Xperia Z2 and Samsung Galaxy S3 (d2lte) and they both enter the LTE network instantly.
I'm guessing that the problem has to do with the modem. Is it because it is a European device and has no LTE network support in Canada?
I have downloaded close to 10 different ROMs tonight and plan on finding one that suits me as well as try to find one that actually allows me to use the LTE network.
Thanks in advanced for anyone interested in helping me out with this issue.

This is impossible to answer without knowing who your network provider is. Some use different bands than others.

Virgin mobile. The bands are: 1700B4 2600B7, if they share the towers with Bell. My phone is capable of those bands.

Who's your carrier?

Virgin Mobile, so basically Bell.

My guess is that it will be D803 HERE. If you have ROM on your device then check model name under settings->about phone. Should say D803, but it also may be wrong depending on the ROM you flashed.

Mine is the D802. I tried flashing a D803 Bell modem earlier today and that did not work. Had to restore EFS and restore ROM.
Edit: Pretty sure I just bricked my phone. Can't boot any rom now... this is ridiculous. I backed up my EFS and when I restore it does nothing.
Edit2: Nevermind, false alarm. That Bell modem is not going to work for me though. D802 doesn't like D803 basebands

Did you try D802 modem? If not then flash the D802 modems and see if you get a winner

That's the problem though. There is no Bell baseband for the D802, as the D802 is the Intl' phone
Is it possible to modify the baseband to include the frequencies of Bell's LTE network in Canada?

SIM Unlocking Sprint Galaxy S5 G900P on Lollipop 5.0 OA6

This is a compilation of threads that I used in order to SIM unlock a Sprint Galaxy S5 G900P that came with Lollipop 5.0. I have always used the SSU.apk from this incredible thread in order to unlock my sprint Galaxy S4, S5 and Note devices. However, whenever I install the apk and try to run it on 5.0, I get an error saying that the application (SSU) stopped working or something like that and it doesn't even work.
Just to be clear, I didn't came up with this idea. This is just a compilation of different ideas that I found on XDA on different thread to accomplish this.
Disclaimer: Do this at you own risk. I am not responsible for anything that happens to your device. I can only assure you this worked for me.
Use this steps to Sim unlock you G900P from Sprint running Lollipop 5.0
1. Downgrade your ROM from Lollipop 5.0 (OA6 ) to Kitkat 4.4.2 (NE5) using this link . Yes you can do this!!!
-Remember for this step you need Odin
2. Unlock you device by Installing and running SSU.apk using this thread
At this point your device should be unlocked. If you want to go back to Lollipop OA6 proceed to step 3.
3. Download the Lollipop 5.0 ROM OA6 from here and flash it using Odin by following the same steps on point 1.
That is all. I hope this helps you guys as much as it did to me.

Ok so its sim unlocked. Does that mean you can use it with other gsm carriers?and have you?thanks

Hi guys, i just bought the S5 Sport on Ebay and intend to unlock it to use with the GSM network in NZ. Unfortunately, this device comes with android 5.0 lollipop that can't use the App SSU to unlock
I have tried to download the older android version on Sammobile but i got the error message Fused 2 > Bin 1 when i tried to downgrade from 5.0 to 4.x. Just google the this issue and find out the reason that the bootloader is locked at 5.0 version, Samsung just only allow me to go to higher firmware, not the old ones
I also have tried to root and install Custom recovery (successful) and install the custom 4.x rom. Tried exactly what the other post said ( download the one for G900p and reflash the Kernel of G860P) but the phone keep restarting (i've tried many roms on XDA, on one works)
So anyone help me to how to downgrade the android of this S5 Sport Or another method to unlock Sprint S5 sport on 5.0 please.
thank you

Same issue, and also made another post just like you. Still no answers, I guess this is a common issue for S5 Sport users

I'm still unable to unlock my Sprint Galaxy S5 for international carriers - ran SSU under 4.4.2 - phone recognized the GSM sim but no signal acquired. Going into Mobile Networks, phone is unable to find any available networks. I have selected GSM/UMTS in the Network Mode selection.

Will this work for the new G900PVPU2BOD3?

Did you try changing to GSM network? Settings -> Mobile Networks -> Prefered Network Type -> GSM/UMTS ? I am able to find the signal after doing this. Calls/Messaging works. But data is very unstable.

Yes. It works with my GSM sim in India after following the above steps. Had to manually change the network type to GSM/UMTS (from CDMA) in settings.

Did you unlock it in 4.4.2 or in 5.0? Downgrading is not an option in the s5 sport and SSU.apk crashes in 5.0. GT tools doesn't support it and the development is discontinued at the moment. I ran all the steps of the s5 and all i need is the Sprint unlock.

Downgrade baseband
So I've been able to downgrade the baseband on a L720t to that of 4.2.2 and I was able to connect with US sim card. Has anyone tried to downgrade baseband on s5?

s5 Unlock for US sim inst available. I manage to unlock the s5 sport for outside US Only (claro) Thanks to @idone

Hi! I spent most of the day reading your discussions and I learned a LOT (thanks!)
I have a similar case with a Samsung S5 SM-G900P from Sprint (but internationally unlocked by Sprint).
1) Background:
- I just moved to France from the USA with my Sprint Samsung S5 (SM-900P, running on Android 5.0 Lollipop)
- My service with Sprint terminated this week.
- I have purchased a French SIM card from the second largest French carrier SFR, and they confirmed activation of the line.
- I skyped Sprint from here and Sprint willingly unlocked my device for international SIM cards (GSM, etc)
2) My Issue:
- My Samsung S5 detects the presence of my new SFR sim card (it has even installed the SFR toolkit app to manage the SIM card), but it still displays "invalid SIM card"
- I try to perform a "UICC unlock" just in case (as recommended by Sprint) but it gives an error message (error 407) after initializing the app. Here is where the international service guys of Sprint just drop the ball for an ex customer.
- ((I have the APN codes and info for the SFR network, if needed)).
- First I tried factory resetting the device and tried again to UICC unlocking but it keeps popping up an error message after trying to do so. I have tried in different ways (with Sprint SIM card, with French SIM card, without SIM Card, without SD storage memory card on it) and same result.
- Then I read that I could force that with the SSU.apk app. Like others, when I try to run the app in Android 5.0 it stops.
- I read that some people downgraded to Kitkat 4.4 or less to use the SSU app. I downloaded the almost 2 GB of firmware for that and got ready for it. However, I have a Mac, so I couldn't install Odin (only for PC) to downgrade to KitKat 4.4 and use SSU.apk to force unlocking of my device (which is already unlocked for international use by Sprint... but with the issues mentioned above).
Any ideas on how can I perform this last step (letting my Samsung S5 device now that he is free!) so it stops saying "Invalid SIM card")? Any guidance to a newbie is really really appreciated

my g900p start to downgarde via odin error to fail aboot . how am i downgrade g900p?

Awesome, thanks for this!
Works great!

Calls not working after manual update to oreo

I got impatient and used the LG UP software to manually update my LG - HD870DS to oreo using the official lg firmware that released for the EU version. the software is working fine with almost no issues (including the quad-dac, unexpectedly). But I cant make any calls. The mobile networks option is greyed out and it says 'service disabled' . The imei number is showing fine. I dont want to rollback as, the update is quite good. Anyone know how to fix this?

EU does not have any Dual Sim Variants, you can't flash a Single Sim Software to Dual Sim.
You're a member of XDA Forum, so honestly you should know that.

Simply reflash your variant kdz... The modem are different

I was unable to find the kdz for my model, can someone give me a link? (My model is HD870DS)

h910 3g issue

Just bought it, entered apn mannually and only get EDGE. stock firmware. Tried different carriers, no 3g at all, stuck on EDGE.
LTE doesn't exist in my region.

Flash the US996 KDZ and see if that works for you. Since there is no H910 KDZ, if you want to return the phone to an H910, you will have to root it, and then flash one of the H910 return to stock zips.

Flashed, now it says : "Enter password to unlock, 30/30 attemts remaining"
hard reset helped, but still no 3g.

Well now that you are on US996 firmware, search for posts about enabling additional bands .. there are several around here and the hidden menus that you need will now be available.

in *#546368#*996# - field test - modem setting - rat selection - choosing any option and still 2g only, if I choose wcdma only - no service.
In "network mode" submenu only option that I succesfully can choose- "Automatic", anything else - "FAIL".

What carrier are you using? What bands do they support?
-- Brian
---------- Post added at 05:47 AM ---------- Previous post was at 05:44 AM ----------
You mentioned WCDMA .. is that the 3g tech your carrier uses? If so, you can try flashing the VS995 KDZ and might have better luck. The H910 is a GSM / LTE model.

Im using kyivstrar, ukraine. It is gsm-lte. Only 2g-3g in my region. 3g : 1965-1980/2155-2170 mhz. I thought wcdma is not cdma, but 3g.

Yea, talk about posting while asleep. You wrote WCDMA, I replied WCDMA, but all I saw was CDMA. Ignore that...
The H910 should be compatible without having to make any changes: link.
Hmmmm....
-- Brian

Yes, I checked frequencies before buying. Then double checked after got 2g-only. Changed sim, changed carrier, flashed us996, still 2g.
