[Q] Need help.. AT&T or Developers edition - One (M8) Q&A, Help & Troubleshooting

Hello, im from Chile and i want to buy the M8, the thing is that here in Chile, the LTE bands are 2600mhz and 700mhz, but the developer doesn't support 2600mhz, just 700mhz.
What would you choose, the developer edition or the AT&T (obviously i will have to s-off and SIM Unlock it and change the rom to delete all AT&T stuff)?

any advice?

no answers? :S

Developer device is same hardware as AT&T device....I got confused on their site as well,but they are same except for carrier bloat and unlocked bootloaders

good to know that.... but does that means that developers edition comes with LTE 2600mhz too?? or just 700mhz (17/2/4/5)?
i need bands 7 and 17 in Chile for LTE (2600mhz and 700mhz)

Only LTE Bands 17/4/2/5 are supported on the Dev device.

[q] Developer or Unlocked M8 doesn't have the 700mhz AT&T LTE bands.

Has anyone bought either one? I just talked to Htc and it doesn't have those bands. Only 1700mhz

I believe the developer edition is essentially the AT&T version of the M8 just unbranded of course, the Google Play edition is missing one of AT&T's LTE bands I believe. I could be wrong.

Dev and standard unlocked are unbranded AT&T. Scroll down the page to see the chart. From wikipedia, 700mhz is band 17 so they should both be able to access LTE on 700mhz.
GPE has 1700mhz(AWS) for 3G while dev doesn't.

LTE bands help.

I recently won a m8 in a contest. And through lots of searching I'm stuck, I live in the UK and my phone is from the US. I want to know if my phone has the right hardware to get lte on bands 3 and 7 as I'm on ee. But I cannot find out anywhere what hardware is inside the device, any suggestions? Thanks.
Check the preferred network (in settings) if you can enable lte connectivity.

Hi!! a have the HTC One® Developer Edition (M8) and this supports the followings Bands in LTE: LTE Quad Band (Bands 17/4/2/5).
Check the exact model of your M8, with this tool: https://play.google.com/store/apps/details?id=org.tritonsoft.cidgetter&hl=es-419
Cid code is needed to find your exact model and get the description of networks supporting.

Any carrier branding (Verizon, Sprint, AT&T, T-Mobile) on the outside of the phone or on the OS (splash screen, etc.)? Mosts US M8s are branded, aside from Dev Edition, unlocked, or GPE.
As long as its a GSM M8 (Verizon and Sprint are CDMA/GSM) in theory you should be able to flash a different radio to get the proper band compatibility, even if your model doesn't officially support the needed LTE band (unlocking of bootloader and S-off required).

Unlocked USA Edition LTE Bands?

Can anyone give me some clarity as to what LTE Bands the Unlocked LTE USA Version of M8 supports?
Is it the same as the Developers versoin?
I cannot get a clear answer from HTC Tech support.... its unbelievable.
I work in Europe/Germany alot and am trying to find out if it will work there...
Or can someone run this CID checker against their unlocked USA edition?

From what I understand, yes. My understanding, the only difference between Unlocked and Dev Edition, is that the latter comes bootloader unlocked.
Whether the device works on LTE in Germany is a difficult question to answer. It seems that the more recent firmwares support more bands than the specs would suggest.
heres the lastest answer from HTC if anyone cares:
the LTE bands of Unlocked US version of HTC One M8 is 1900/2100 MHz.
though i have gotten 2 other answers before so who really knows.

I don't think that the info is correct. That is missing 3 of the 4 bands needed to make the phone work on AT&T in all markets (850. 700 & 1700); as well as missing 2 of the 3 needed on T-Mobile (700 and 1700).
Exactly... How does no one at HTC know this? I will email them back
Sent from my Nexus 4 using Tapatalk
I have found the info via android central:
http://www.androidcentral.com/developer-and-unlocked-htc-one-m8-ready-order
And speaking of networks, HTC has confirmed to us that the developer and unlocked versions are based off the AT&T SKU, meaning the bands line up in the following manner:
•2G: 850/900/1800/1900 MHz
•3G WCDMA: 850/1900/2100 MHz with HSPA+ up to 21 Mbps
•4G LTE: 700/850/AWS/1800/1900/2600 MHz
Finally got it figured out.

T-Mobile bands...

I'm VERY concerned about buying this phone now. T-Mobile have only listed LTE bands 4 & 17 on their site.
International
Quad Band GSM; LTE: 4, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
What in the eff?
Des just answererd this question on Twitter: https://twitter.com/askdes/status/581568102015569920
It has:
GSM - 850/900/1800/1900
UMTS - B1/B2/B4/B5
LTE - B2/B4/B12/B17 with CA + B3/B7 roaming
This is the perfect T-Mobile phone.
So the T-Mobile version does not have 1700, and is therefore identical to the other models? Do we know if it includes wifi-calling, or if we would be able to flash the T-Mobile ROM onto the unlocked dev version?

It does have 1700! That's Band 4, and for both LTE and HSPA.
The T-Mobile version also supports WiFi calling and texting. I have no idea if the T-Mobile firmware can be flashed to the unlocked version, but I don't see why it wouldn't be feasible.

T-Mobile (Des) confirmed: 2, 3, 4, 7, 12, and 17
AT&T lists: 2, 3, 4, 5, 7, 12, 17, and 29 (adds +5 and +29)
HTC Dev & Unlocked versions (per HTC on Twitter): 2, 3, 4, 5, 7, 12, 13, 17, 29, 30 (adds +5, +13, +29, +30)
Maybe the T-Mo phone supports more that could be unlocked, who knows. The extra bands aren't useful to me.
Sorry, but I just want to clarify.
Do all versions of this phone support BAND IV UMTS or not?

HTC has done this on the past couple of phones. Only the T-Mobile phone will do their specific bands (HSPA+). On past models I don't recall anyone getting the ATT/DEV models to work with those T-Mobile bands. I don't believe we ever found out why. Some speculated it was due to cost to license all the bands, or that it is actually different hardware. The M7 and M8 were both like that.
If you are on T-Mobile, I'd get the model specifically for them.

Oh yeah I remember my Dev version being like that. Fortunately, I live in an area that has been upgraded to mostly lte. This was actually beneficial for me and maybe others in the same situation because it actually saves battery life when the phone isn't constantly switching between edge, 3g/+, and lte. I'm sure many others have been in an area that's barely out of lte but still within h+ range and it's still slow as edge or even slower.

Yes, it is OK if you live in a major area that has lots of LTE. Here just north of LA, I get into the other bands pretty frequently.
I am not sure this was answered? Do all versions of the HTC one m 9 support band 4 UMTS? Many ATT carrier unlocked models are for sale and no one seems to know if they will pick up the UMTS 1700 band 4 on T- Mo?

They will not pick up the T-Mobile specific bands, which use 1900/2100 for 41bps speed. They will work with the T-Mobile LTE band.
Wow, still a mystery. I have the AT&T SIM Unlocked One M9 and I have a TMobile prepaid SIM and get Edge, 3G, 4G, LTE Band 2,4,12...I cannot find an app that shows the actual WCDMA (4G) Bands ? But, it notates 42 MBPS when it says HSPA+ 4G using Network Signal Info-Pro App..and also shows 384 Kbps when it says 3G....
So, seems Des is correct unless the Network Signal Info Pro app is wrong?
I turned off everything except WCDMA, and this is what I get being reported by LTE Discovery. HSPA+ @ -113. I have a ATT unlocked M9. I do have the T-Mobile 2.11.531.19 firmware installed as well as the T-Mobile rom.

Thanks but as I mentioned I cannot find an App that shows the WCDMA Bands to confirm. As you can see even LTE Discovery says N/A for DL and UL Freq...when on WCDMA...
The only App I can see that helps is Network Signal Info Pro...and unfortunately it is limited and shows me the below in my market;
HSPA+ 42.2 MBPS
HSDPA 7.2 MBPS
UMTS 386 KBPS
But, does not indicate which Band or Frequency ?
Anyone know of an App or Command that will show WCDMA Bands???

Which HSPA/UMTS band does the M9 unlocked US version support?

Found much conflicting info on HSPA band support for the US unlocked/developer model.
htc.com says it supports 3G UMTS: 850/900/1900/2100 MHz. But is also says it supports 4G LTE: FDD: Bands 1,3,5,7,8,20,28, which is COMPLETELY wrong so i don't know if to trust htc.com.
Can anyone confirm the UMTS band support for this device? I am most interested in 900mhz UMTS because of trips to New Zealand where 900 mhz UMTS is often used.
Thanks!
Bump.

Is that really true?
I am looking into getting the HTC One M9 through AT&T but may switch to T-Mobile in the future.
As such I want a phone that fully supports both networks ...
I found a thread that it is supposedly possible to flash the AT&T phone to support developer ROMs but I can't find any information whether it is possible to also change band support. According to GSM Arena the AT&T version of the phone also supports LTE band 4 and 12 (needed for T-Mobile) but it doesn't support VoLTE on band 12, nor does it have 3G AWS (1700/2100), though of course there is a T-Mobile version of the phone WITH support for all of those.
Can I simply flash my phone so that I can (a) use CM13/AOSP roms and (b) so that the radio uses the proper AT&T or T-Mobile bands and tech?

All this info is about LTE bands. I am curious about HSPA/UMTS bands. I would like to know what it supports out of the box, not what I can with mods.

The T-mobile version of the M9 supports the most bands. The AT&T and Developer Edition are identical and are missing some bands needed for t-mobile LTE (Volte) support in some areas. Flashing different radios will not enable bands the phone does not have. Theirs more information in the T-mobile M9 forums

Thanks for the reply. I have checked GSM arena, plus anything else I could find on google. I don't see a listing for the unlocked/developer edition on this page. I see EMEA, Verizon, ATT and T-mobile.
And yes, sorry, I didn't realized there was an AWS for HSPA, i was just thinking about band 4 LTE on ATT which I think is AWS.

It's pretty difficult to find out info on band support, and I have no idea why. It should be readily available...
Anyway, have a look at this: http://wireless.fcc.gov/hac_documents/150813/9135276_21.PDF
Based on that, there are four models sold in the U.S., which are:
0PJA100 (which appears to be the AT&T version)
0PJA120 (which appears to be the TMO USA version)
0PJA200 (which appears to be the Sprint version)
0PJA300 (which appears to be the Verizon version)
The AT&T model supports the following: UMTS 850MHz, 1900MHz and 2100MHz.
Now, that said, if you look on AT&T's site, they list their model as 0PJA110, so obviously either the FCC site is wrong or the AT&T site is wrong.
I happen to have the 0PJA110 model, which is also the Rogers model (so it would make sense that the AT&T version is 0PJA110 because Rogers and AT&T generally have the same devices, and their networks are generally the same frequencies). Based on HTC Canada's site, the Rogers model supports UMTS 850MHz, 1700MHz, 1900MHz and 2100MHz.
Now, for the assumption: From what I have read (but I haven't personally confirmed), the unlocked and developer models are the same as the AT&T model. If that is indeed the case, then you have your answer: No UMTS 900MHz support the unlocked and/or developer models (in fact, not UMTS support on any U.S. model).

I know this is a delayed followup, but I wanted to say thanks for this. I finally got HTC to confirm that UMTS 850MHz, 1700MHz, 1900MHz and 2100MHz are the official specs for the US unlocked edition(which, oddly, is marked 0PJA110 on the back).
I am pushing them for a refund for false advertising. I was so concerned that these specs could be wrong before I purchased the phone, that I did a chat with HTC and they assured me the correct specs were UMTS 850MHz, 900MHz, 1700MHz, 1900MHz and 2100MHz. Once they confirmed these specs for me, I purchased the phone. Now they confirm they told me wrong. Very frustrating experience.
I am waiting to hear back about getting a refund. I am hoping the come through, this is crazy.
