Developer Edition and T-Mobile and LTE - One (M8) General

Hi, I live in southern California. I was looking at purchasing a developer edition m8 on ebay. I needed to switch from verizon to t-mobile. I tried to find info on wether or not the developer edition would get lte on t-mobile's network. I could not find any info on it. I had an m7 for verizon that when I put a t-mobile sim in it would only connect to the edge network. So I found a deal for a developer edition m8....
I decided to buy it and the answer is yes, the developer edition m8 on t-mobile's network does connect to lte. Here are some screenshots of exactly what the lte connection I am getting is...

I am currently running Leedroid 7.3 and firmware 4.20.531.4. I get lte all over riverside county and la county with this configuration. I was worried that with a non "t-mobile" m8 that I would have issues.
Again the developer edition definately does get lte connectivity on t-mobile. In southern California anyway.....

T-Mobile uses Bands 2, 4, and 12 for LTE. The DE supports Bands 2 and 4, but not 12. So while LTE might work in a many locations, you won't have LTE if areas where they are using Band 12 for LTE.
Additionally, the DE does not support Band 4 (AWS) for 3G; which is the band most commonly used by T-Mob for 3G. So if you need to fall back to 3G (no LTE), you will probably not get it and drop down to EDGE.
If you like, you can s-off the phone by sunshine ($25) and then be able to (after changing CID & MID) flash the T-Mob radio to enable the T-Mob bands. Or even "fully convert" the phone to stock T-Mob software.

Flashing a T-Mobile radio won't enable AWS. A radio flash is just tweaks to how the phone handles different signals. Actual Bands are lower level settings that aren't touched by firmware.

All GSM M8's (that is all but Verizon and Sprint) are identical in hardware. If the band support was not incorporated in firmware, how else would it be?
Pretty sure folks have been changing the band support by flashing different radios. If you know otherwise, please cite your source. I'll do the same and try to find a thread(s) where folks have successfully changed the band support.

Currently can't get you a source, but once I'm off of work I will do so.
An example is a current thread that's going around with changing bands on Qualcomm devices. The last time I went through it. Only Verizon's m8 had the specific app that would enable it to write any changes via QPST.
All gsm M8s are identical in nature, but carriers change the actual bands. Radio files are just the actual adjustments to overall RF Rx/Tx. If the band isn't enabled that part of the firmware is just ignored.

Hero Approved for AT&T 3G Bands

No mention was made of a Hero with 3G that'd work on Rogers or AT&T back at its announcement a few days ago, but HTC has been getting awfully good at making phones that work properly around these parts -- so we can't say we're entirely surprised to see a Hero approved for WCDMA on Bands II and V gracing the FCC today. For the record, Bands II and V are 1900 and 850MHz, respectively, which is exactly the combo AT&T subscribers would need to flip the switch on high-speed data. We're not sure if this negates rumors that the Hero would be coming to Sprint, but if we can just get this version released and in our hands, you know... maybe our minds would be operating with a little more clarity.
t-mobile USA???
nothing for us?
Hopefully it's quad band
I was hoping this phone will come to Sprint.

there was a rumor originally that the Hero would be coming for Sprint. just because a ATT 3G band model passed the FCC, it doesn't mean that the phone isn't still going to come out for Sprint. it's still early, be patient!

According to pdadb.com it will be the G1 Touch (HTC Hero 100). Only difference between this version and the regular Hero is that they added the 1700 band to work here. Supposedly coming this month.
Tempted to get this, but the screen resolution might kill it for me
According to Gizmodo, T-Mobile says there will be no Hero released by them. http://gizmodo.com/5310109/t+mobile-straight-out-says-no-htc-hero-from-them
quick question if I can order one from england can I use it on ATT with 3G?

No. If you bothered to google this question, you would have found about eleventy bazillion links to this question, and they all say no, you can't. Even if Verizon allowed unlocked devices (which they don't), the Nexus 4 is GSM only, and Verizon uses CDMA for calls. No calls, no 3G data, no 4G data, no LTE. Not a sausage. Well, 911, but that's a given.

True Verizon uses CDMA for it's 3G network but the Nexus 4 does have LTE, and Verizon uses Band 4 according to this list, shouldn't this work?

NO!
But this would be possible if Verizon allowed unlocked devices, correct? Because both can support 1700 mhz
I know this is regarding the Nexus 5 but I'm assuming it's the same reason:
Verizon is intentionally blocking the Nexus 5 from their network since the Nexus 5 has all the ability to run on Verizon with no issues. The Nexus 5 radio supports all of Verizon's frequency bands. Verizon doesn't like universal service network phones that are new unlocked cell phones they can't lock into that old 2 year services contract scheme that has made them rich

And if a frog had wings it wouldn't bump his ass when he hopped.
But yeah, if Verizon ever allowed unlocked phones, theoretically it might be possible to get LTE working on it. But the Nexus 4 doesn't have CDMA, which Verizon uses for telephony, so you wouldn't be able actually use it as a phone.

Yes correct

That's where I bought mine. Make sure you buy from amazon or at least FULFILLED by amazon in case you get a defective or a questionable unit. Don't huy from seller FreeTaxMse... I got a bad unit from that seller and when I returned the item, they were trying to blame me and accusing me that the unit and box don't tally... luckily It was fulfilled by amazon you I dealt with amazon. My N910C runs on AT&T via straight talk. So far so good. Not sure about Tmobile though. I always buy my phones from amazon.
Edit: here is my thread about the BAD unit:

Due to the LTE bands AT&T uses you will not get LTE. You will get Edge, 3G, HSPA, and HSPA+.

Then on the Main Menu >> choose Option [2] UE Setting & Info
Then Option [1] Setting, then Option [1] Protocol, then option [2] NAS, option [1] Network Control, option [4] Band Selection, option [4] LTE Band Part1 >>>> then you will see the bands :

My 910C had hardware issues, I received a 910H in place of it.
Edit: Now I am wondering if my C version had not had hardware issues would I have had LTE with it. Oh well, the H version is plenty fast with HSPA+.

At Key Input you can type Q21124 and it will take you to the same page.
I have the n910c on att in ny. I only got hspa+ until i talked to an att rep onljne and they did a few things on their end and now i have lte. My sim card was in a nexus 4 before hand.
Well I sure wish my C version had not been bad or maybe that I got aC version as a replacement because LTE is a nice thing to have.

S8+ SM-955f signal icon question

Alright i got a simple but probbaly silly question that i am sure someome has the anwser to. I bought a unlocked S8+ SM-G955F and currently using it on Cricket Wireless . My question is though after putting in the correct APN informatiom for Cricket i notice that on my status bar top right were is shows the single and data connection. Instead of it showing 4G LTE like on my old S7 Active it only shows LTE and if i get a bad signal spot it will show H+. So did they remove thr 4G LTE icon and just replaced it with a simple LTE or is my phone configured worng ? Thanks
Well those icons and in fact the entire firmware are heavily carrier dependent in the US. You'll see various 4G LTE icons when you get a carrier branded phone that is part of each carrier's marketing scheme and not the Samsung or generic Android icons you would for an unlocked or any unbranded international device. Check the photos for a comparison before/after I flashed the unbranded firmware onto my ATT S8.
The important point is to check whether you do have actual LTE connection, for example by going into the menu when you dial *#*#4636#*#*. You're most likely fine and have nothing to worry about.

Not quite. LTE is LTE. 4G is something different in the specification.
H+ is HSDPA, 3G ist one Level below that.
So, the full row would be
E - 2G - 3G - H - H+ - LTE

No, LTE refers to the Band. 4G to the modem. They are two different parts of the same tech. Like 1gig Ethernet and cat6 one is a protocol, the other a medium...
So, another question to tag along with this one, very similar...I have a G955FD running on ATT in the us. Like OP states, the status bar shows "4G" and nothing regarding LTE. I have confirmed via LTE discovery that it is indeed connected.
Is there a root or other method to modify or customize that icon to match ATT or another carriers specific 4G LTE logos?

Do all versions of the Mi9T come with Band 28 (700Mhz)?

The official Xiaomi website suggests the Mi9T supports LTE FDD: B1/B2/B3/B4/B5/B7/B8/B20/B28. However many sellers have told me that their Mi9T does not come with Band 28. My understanding is that the box itself doesn't show the bands of the phone but the booklet inside the box does - thus perhaps confusing some sellers.
So, my questions is, does anyone have a definitive answer if all Mi9Ts have the same bands and more specifically, do they all come with Band 28 (700Mhz)?

I want to know this same exact question.
Because here in Brazil many resellers don't know if it has or not the band 28 (700Mhz).
Yes the "Mi 9T" version have B20 and B28, 100% sure cause it is written on the "phone's little book" xD
Xiaomi make different phones for different regions with different Bands. We can't rely on their website either. It says that the Redmi Note 7 has Band 28 but the RN7 has 3 different variants, only one of those has Band 28.
My question is whether the Mi9T is like the RN7 with different bands for different regions or whether all Mi9T have the same bands?
Just use the App "Cell Info Lite" in different places. It will show you the current band of your Mi9T.
I got Mi 9T from Hong Kong that came with the HK/UK charger. it has B28. I have confirmed it works.
The MI 9T global device has band 28
I am asking if ALL Mi9Ts have Band 28. Many sellers don't list the bands for the phone and other sellers say it doesn't have Band 28.
GSMA claim that (unlike other phones like the Redmi Note 7 which has multiple variants) the Mi9T only has one variant which has Band 28.
Does anyone know the official answer?

I just got my Mi 9T from TobyDealsAU today, and the booklet says it has band 28, but in the cell info app band 28 isn't appearing... When I put my sim in my Mi Mix 2 it connects to band 28 instantly, bit disappointed...
Maybe it's something to do with MIUI Global, going to try flash Xiaomi.eu in a week when I can unlock it, still disappointed though
Straight out of my instruction manual in the box
1/3/7/8/20/28/38/40
which is not accurate because it supports band4 too. I guess since it's made for Europe they don't list it there. The best way to find out is to check FCC or similar regulatory bodies with the device ID.

Ok, I looked up on FCC. Mi 9T https://fccid.io/2AFZZ-XMSF10G
If you look at the LTE reports, it has approve cert for these bands.

I don't know if that's conclusive since band 28 is Asian maybe FCC doesn't test that. Overall I'm guessing this device doesn't support any 700Mhz band like 28 or 12 etc.
