I've got an unlocked gsm h8 that I'm using on the german o2 network. When I bought the phone, I thought that "unlocked" is the equivalent of "unbranded". However, after the Lollipop update I noticed that I got the T-Mobile version of the OTA, 4.19.111.2. Indeed, the CID of the phone is T-MOB101.
There is no obvious bloat on the phone, unless you count fm radio. But perhaps I just don't know what is there from the Telekom and what's from HTC. Moreover, other carriers, for example O2 seem to have the "higher" ROM version numbers, 4.20.xxx.x. What is the difference betwern them? Is there any point on spending time and effort to switch the CID and convert from T-Mobile to O2 or any other version? Is the "truly unbranded" version 4.16.xxx.x any different? They all seem to be Android 5.0.1, but then what do those numbers in ROM versions stand for?

Sorry if this has been asked/answered already, I wasn't able to find if it had.
Is it possible to reflash a European TP2 with the TMO USA TP2 radio ROM to enable TMO USA 3G on the European version?
I had come across a chart about a week ago of hardware differences between all the different versions of the TP2 and it appears these both have the same radio, so im assuming it may just be software registers or something that enable/disable certain frequencies?

I am fairly sure you can't.

Frequency is a hardware thing, you cannot flash a different radio to change the frequency of the phone.
Ok, so I haven't been an HTC user since the HD2 (Loved that device). Bought a T-Mobile branded one m8 and got the carrier unlock code with the phone. Unlocked it, used all in one toolkit to unlock/root/twrp. Now I didn't have any issues with the phone (got mms and 4g lte no problem) but sick of the bloat, t-mobile startup screen etc. As I'm new to the HTC game, is S-Off worth getting for the $25? I'm wondering if the ATT radio will make my phone work any better, or an AT&T rom (stock or custom) would improve the phones connectivity. Sometimes people say i'm cutting out during a phone call (I live in Chicago, this usually never happens to me). Any advice would be greatly appreciated, I have no problem paying $25 , just don't want to if it's not needed.
Personally, I'd S-OFF and then flash the Dev Edition RUU so, in essence, make the device an unbranded handset free of bloat

I went ahead and got S-Of and flashed Insert Coin. What I'm wondering is if flashing an ATT radio will help strengthen my connectivity (the LTE seems slow).

Assuming you are with T-mobile, the answer is probably no, and it may actually make things worse - especially if you are concerned about LTE. T-mobile and AT&T are both GSM providers, and you can switch between them, but they don't perfectly overlap in terms of bands used.
That said, since you are S-off, you can try it and see what happens. If you don't feel it is an improvement, put it back on the T-mobile radio.
I'm actually using AT&T, that's why I was wondering if the Radio change would help. The phone was originally a T-Mobile phone that was carrier unlocked via a code tmobile gave my friend.

Ah, then yes, you should switch radios - and for the same reason.
I would also suggest switching to the Developer Edition software. It is functionally identical to the AT&T version, minus the AT&T (or T-mobile) crap. In fact, the DE and AT&T versions only differ in CID - they share the same MID.
Was thinking on buying the H815. Wanted to know a few things before I do since I have till Monday to research it..
1. I hear there is the US and a International version? What's the difference? Which is 'better'?
2. I take it that the H815T and so forth are versions for other countries?
3a.. From what I've learned each carrier has their own version of the G4, but it seems that a lot of sellers selling the H815 have bought them from AT&T, Verizon, etc. How does this work when the VS986 is the Verizon version, etc.
3b. It seems that these H815 versions have bloat even though they are carrier unlocked?
4. Do all H815 phones have the boot loader unlocked or just the International version or?
5. I also heard someone say that I will lose out on DRM with the International version? what exactly will I miss out on?
6. I heard that the International version gives better performance, faster updates, etc. Is this correct, what other benefits are there? Do I lose anything from the International version?
7. Regular G4 question: I hear a lot of the phones do CDMA, some only do GSM, with the options to change the Network mode and APN settings, it seems that the G4 would work with any US carrier, am I wrong? With those settings that can be changed it seems so. I know some versions do certain bands and such but as long as your G4 does the bands your carrier does, all should be good, yes?
8. Additional question: How does one check to see if the boot loader is unlocked?
Thanks!
I'm surprised no one knows these answers. Hmm..
What's up guys?
I'm currently in Japan and own a US Unlocked HTC 10. Currently I'm on ATT and while out here, I have all my bars and LTE. However, ATT is mad expensive as far as international, so I need to get a Japanese provider. I was gonna go with docomo or Softbank which all support HTC 10 LTE and 3G bands. I think like 18 of them. Anyway, what is the advantage to changing my Cid and mid and fully converting to international WWE? Will it help with compatibility on Japanese networks? Or is is just how fast I will receive updates from HTC?
Bump?
Just the recieving of updates. Do yourself a favor, S-OFF your phone and convert it to WWE. Much easier life when it's on WWE plus you can use it on AT&T when you're back and you get faster updates .
Regards, Talpes
If it's just updates, I may just leave it. When firmware updates come out, I always use RUUs cause I like to completely wipe and reinstall everything. If I were to get better signal strength or compatibility with Japanese networks I would do it.
However, I am S-off, unlocked, so its not difficult if I need to.
Thanks man!
Outside of the iPhone which is a "special case", AT&T has been known to only provision VoLTE and/or WiFi calling for users of AT&T-branded and sold [Android] phones; however, every once in a while, they make an exception for a particular model (e.g. / famously, the Pixel 2).
In the case of the M9, both the AT&T-branded (locked or unlocked) and unbranded, factory-unlocked models share the same HTC model # (OPJA110). I have also noticed that if I take a clean IMEI from an unbranded model and run it through various AT&T IMEI checkers, it almost always returns a positive result, as though this IMEI exists in AT&T's database. But if I take, say, a clean IMEI from T-Mobile-branded M9 (OPJA120) and run it through the same checkers, they say this isn't an AT&T phone (which would be correct!).
So this raises the question: in order to achieve VoLTE on an M9 on AT&T, do you absolutely have to have an AT&T-branded model? Or has anybody had success with getting AT&T VoLTE working on an unbranded, factory-unlocked M9? That an unbranded phone's IMEI passes the AT&T IMEI checks would *seem* to suggest that AT&T might treat *all* OPJA110s as AT&T devices, not just the ones that happen to have their logo printed on the back.
(I realize that if you have an unbranded phone, you may need to change CID and flash the AT&T firmware on the phone to get VoLTE to work...my question is solely about people's experience with the AT&T/network-side of the equation. An unbranded phone with an AT&T CID and software should be functionally identical to an AT&T-branded phone, but the question is whether the AT&T network will refuse to provision VoLTE for one's SIM/account because they don't see the phone as an AT&T phone based on its IMEI.)
Thanks!
