[Q] Change radio (AT&T to T-MO) - G2 Q&A, Help & Troubleshooting

I have the at&t variant G2( D800) which I unlocked and am currently using a t-mobile sim, my signal is spotty in certain areas. Is there anyway to flash the baseband from the t-mobile variant ??

Try it. You'll have to have the phone unlocked to read a T-Mobile SIM
Worst case scenerio is that it won't boot. Worse case scenerio is that it boots but doesn't pick up all of tmobiles bands.
You'd probably need radio, baseband, rom. I don't know if I would attempt it unless you were comfortable with restoring the hard way.

I already have it unlocked and am using my Tmo sim, but the 1700 UMTS band is what i need for the area I live in. Was hoping someone could verify if the bands acutally change with the roms and baseband before i do it.

[Q] Unlocked G2 on T-mobile

Hi,
I am looking to buy a factory unlocked G2 and flashing custom rom on it like CM10.2, and use it on T-mobile. Just want to make sure I could get LTE speed, correct?
Currently on Nexus 4 on T-mobile monthly 4g, enjoying LTE 4G speed, so, just want to be sure...
I would suggest you still buy the T-Mobile version, depending on what's important to you. As far as I know, the AT&T version doesn't have 1700mhz AWS band for HSPA+ to fall back onto if you don't have LTE. The two devices (D800 and D801) both have the same LTE bands.
Which version are you considering? I don't know if any of the other versions work on T-Mobile's Band 4 LTE, but when I checked a few weeks back, they didn't. You may be stuck with a T-Mobile version.

Factory unlocked, e.g. : http://www.amazon.com/LG-G2-32GB-Un...qid=1382743380&sr=8-3&keywords=unlocked+lg+g2
The specs listed on that page for LTE are:
4G Network LTE 850 / 1800
Neither of those are T-Mobile bands in the US. Are you planning to use it in the US, or T-Mobile in another country like the UK? I think the UK uses 1800mhz, but I'm just speculating at this point. Sorry I can't be more help!

[Q] Will the TMO version work on AT&T?

I just moved to a new state, where my current phone service BLOWS (Sprint).
I want the G2 but I want to try both TMO & ATT to figure out who's service is best for me.
From what I understand the TMO G2 is missing the 850 LTE band and I have no idea if I need it.
"AT&T version (D800) does not support WCDMA 1700 / T-Mobile version (D801) does not support LTE 850"
http://www.phonescoop.com/phones/phone.php?p=4216
What I gather from this wiki I should be ok... http://en.wikipedia.org/wiki/AT&T_Mobility
So, If I get the LG G2 d801 and get it unlocked will I be able to hop networks without issue?
Tmobile d801 on ATT
Hey,
Kinda new on the forums in terms of posting but have been reading for a while.
I talked to an ATT rep today about using the unlocked tmobile d801 on att, here is his response:
"ok here is how it works, if the phone is LTE capable you can get the LTE speed but not right at first, the problem is that our system does not recognize other carriers phones, so it is difficult to get it assigned on the right speed for the device, usually we get on a data connection that does work then file a ticket to have the data speed manually altered to the right connection for the phone, because the system cant do it on its own this usually takes a week or so to get set up properly but once that is done you have the LTE"
He then looked up the specs for the tmobile d801 lg g2 and said that it does get the correct bands.

[Q] LG G2:which model to buy?

Hi,
I am from India. I planned to buy LG G2 Locked mobile from USA their after I Unlock the phone to use it in India.
now i am confused which model to buy?
there are many models in LG G2 (D800,D801,D802,D803..)
Which one perfectly match with my requirement?
Is it possible to unlock the USA mobile from India?
D802, because that version have the most development, but tje 802 is already sim unlocked?
Sent from my LG-D802 using xda app-developers app
Go with D802. No lock or whatever.
If i go with locked mobile the price is very much low when compared to the unlocked phones.In my country LTE is in developing so i don't want LTE.
so i think Verizon - VS980 mobile work with indian 2G and 3G.

If you have already decided why do you ask...
I got my 802 unlocked. Price: 580 but I had to sign up for a 6 month subscription.
D802 of course because is the international unlocked version and all developers working on that plus i m an owner so go for it,you will no regret it !
How cheap is the US version? The India 16gig version is for $570. You get the added advantage of warranty and an unlocked phone.

Get the phone that has the right radio bands to begin with.
I agree with x714x, you do need to get the one that has the right radios for you. GSM is covered an all versions so you'll get EDGE (2g) and voice service with any version, now the question is, which band does your phone company use for 3g?
Talking about radio bands I bought a D802 thinking the lte will work here in the uk but it does not it don't have band 4 can anyone else confirm this,
It doesn't according to this site http://pdadb.net/index.php?m=specs&id=5082&c=lg_g2_d802_4g_lte_32gb

Only get 2G on on Telus (AT&T band), what am I doing wrong?

The phone we have is a SM-G900F international, unfortunately I can only get 2G on this thing while on Telus and won't even connect on Rogers (which doesn't make sense). Is it possible this phone is bricked? If yes, can it be fixed?
Thanks,
Xol

You don't understand what bricked means. If your phone was bricked, you wouldn't get 2G either. You would have the same reception as a brick does.
Your model supports most, but not all of the Telus and Rogers frequencies. So one would expect it to work most of the time. If you have a Telus or Rogers SIM as opposed to roaming on those systems, then open a support ticket with your carrier.
It sounds like your phone is not provisioned correctly. That may be as simple as updating your APN information or may need carrier side adjustments to your account configuration.
If you are in a fringe area, one that is only served by a single 3G /4G band then the problem could be that your phone simply does not support 3G 1700 or 4G 700/1700 that are used in Canada.

Question about bands, and roms....H996 vs H918 for Canadian carrier....

Hi all!
**EDIT** It is a US996, not an H996, my mistake!****
Ok I am so confused on what to do and hope I can get some insight here
I ordered an LG V20 unlocked from Amazon.com. I fell in love with the phone but within a couple of days it started to develop vertical lines on a portion of the screen. LG can take it in and fix it but I find it's easier to do a return to Amazon. I ordered another and it arrived before I returned the other one.
However!
This one, under the same listing, is a LOCKED T-Mobile version, model H918.
My previous unlocked one is H996.
Geeez!
So my dilemma. I am in the US and return to Canada for the summers. I am with Freedom Mobile (once Wind Mobile) who now is LTE (band 66). When I received my first V20 from Amazon I called LG to inquire if my model H996 would work with them, and if it had band 66....because everywhere online it said it hadn't. I was informed it did indeed have band 66 now....even if it doesn't say it on their site or anywhere else online!
I know from research that H918 has band 66.....but....
1. This replacement cost me 80 more on Amazon
2. I'd have to get it unlocked
3. I very much dislike all this T-Mobile stuff on it that I will not use
4. Probably the worst thing is the T-Mobile Start up. I loved my normal H996 LG start up. I know silly, but true!
So I guess my questions are....
A. Does anyone know about this band 66 thing? I am going to call LG again to confirm that the H996 will work if I have it fixed.
B. Does the H918 have anything that the H996 doesn't have? I've researched on here and apparently it has an FM radio....and more roms available.
C. If I keep the H918 and decide to root it....are there roms that can change the start up into something else other than T-Mobile?
Thanks in advance
The H918 (and some other models as well) have the Band IV or AWS or 1700/1900 on the 3G/3G+/HSPA/HSPA+ frequency set (this Band IV in the 3G band only affects 3G). T-mobile uses Band IV on it's 3G network as well as the same 3G bands as AT&T, Bell, ROGERS, Telus (and Canada's little three including Koodo, Virgin Mobile, and FIDO) (for a long while, T-mobile only had the Band IV in 3G set which is why T-mobile needed it's own phone (but most of this has been replaced by LTE (4G, 4G LTE).
The Band 66 serves as one of the LTE bands on T-mobile and Freedom Mobile in Canada (western Canada only at this point) while LTE Band IV serves eastern Canada on Freedom.
If you are the type that likes to customize your ROMS, you will want a phone BOOTLOADER unlocked or BOOTLOADER unlockable like the T-mobile LG V20, G5, and other phones.
The problem with T-mobile phones in regards to SIM unlocking (i.e. using a ROGERS or EE or Orange SIM) is that the use a Device Unlock app (this has several requirements that have to be met before the phone can be unlocked. One of which it has to be on the T-mobile network for 40 days before it's even eligible).
See http://www.gsmarena.com/lg_v20-8238.php for the details of the various models but it looks like that:
Both the H918 and US996 (not sure if that is the same as H996) have that particular 3G Band (so both will work on T-mobile and Freedom (that uses BAND IV exclusively for it's 3G).
So far, the H918 (T-mobile) and the H915 (Freedom) band 66 are not accessible (I'm guessing a future software update will fix that).
The Freedom Mobile version is not BOOTLOADER unlockable (I already tried) though if someone has found another way to get root, then you should be able to put on custom roms or delete the things from the stock rom you don't like or use (I usually do the latter).
The H918 does have FM radio (not sure about the H915 or other models; otherwise, should be basically same (except the phone radio which determines the frequencies and networks you can access).
Hope this helps.

Oh wow! Thanks so much for the info, I had to read it a couple of times to understand....it's all so confusing!
So basically, I should be sending the T-Mobile one back (H918) and keep/repair the US996....I am in Eastern Canada (Toronto) and don't plan on going west anytime soon, ha ha! I'm fine with keeping it stock too....just as long as it works on Freedom, I'm cool!
Thanks again!!!!
You wouldn't by any chance be interested in a trade would you? Brand new US996 for your H918?
