[Q] Should I Sunshine my Unlocked t-Mobile to get ATT Radio? - One (M8) Q&A, Help & Troubleshooting

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.

[Q] Flash T-Mobile Rom on AT&T M8??

I have an AT&T M8 which I unlocked, rooted and s-off'd while under AT&T contract. I then decided to switch to T-Mobile and give this device to my 11-year old son. What I'd like to know/understand is whether I can flash some of the T-Mobile Roms I see in this forum on the AT&T M8 and it work with T-Mobile network? Or do I still need to flash the AT&T Roms?
Thanks in advance for any help advice!

SIM unlocked would allow you to use it on stock AT&T too if you choose to. Also everything seems to be interchangeable unless noted. I would go for Rom with T-Mobile's Wi-Fi calling, which is amazing btw for those who get sorry service.

You should be able to flash either T-mobile or AT&T (Even roms in the international section, I would recommend InsertCoin) roms without any issues. Eleven and has a M8? Damn, i'm jealous lol.

Thanks for the information to the both ^^^^^^^^ of you! I appreciate it. Yes , he is 11 years old, but a good respectful kid and does well in school. With that I'm okay with giving him nice things. If that should change, then Daddy gets the M8 back!!! LOL
Somewhat related question... If I u were to use an AT&T model on T-Mobile, would everything work correctly, 3g/4g? Comparing the frequency bands online, the AT&T model is missing the 1700 band that the T-Mobile version has. Does that mean the phone doesn't have the hardware components to connect to it? Or is it capable of connecting, just that AT&T doesn't use that band? I'm asking because I want to pickup a used m8, but the T-Mobile version is going for around $100 more than all the other carrier's versions... Could I just SIM unlock an AT&T version and be set, or will some things not work?

That's a good question and hoping someone will have the answer. In the meantime I was able to SIM unlock my son's ATT M8 and install a TMobile SIM using stock ATT rom. So far everything has worked and the 4G symbol does appear in the task bar, although I'm not sure if that really means he's getting 4G. I did have to manually enter the APN settings so he could get mobile data when not connected to wifi.
Tmobile apn settings
Would you mind posting the apn settings that allowed your sons phone to work on 4g and send mms? Its the main reason I'm looking into flashing a Rom and would save me a lot of trouble as I have spent quite a bit of time searching for one that works on my phone and none seem to do the trick.

T-Mobile M8 patch 4 Verizon M8

Is there a patch to make my vzw M8 work like it was a native Tmo M8?
No. Hardware is different.
Verizon has CDMA chipset and the TMO verison is a GSM chipset.

That's not true...
My phone is Fully unlocked and gets everything from Edge to Legit LTE.
My phone works. I just need it to work a bit better.
And the reason you want it to work better is because its not the correct version for the carrier you want it to work on.
http://www.gsmarena.com/compare.php3?idPhone1=6233&idPhone2=6074
The bands are almost identical with the Verizon unit missing 1700mhz on the HSDPA side.
Either way if you want it to work like its supposed to get the branded one. Unlocking will work but in most cases something is always missing.
could be specific software, or the way the device works with the network, or an entire band or what ever.
Bottom line is ditch the unlocked verizon and go with a branded tmobile unit.

Since you seem to already know the answer then go ahead and flash a tmobile or any other gsm rom to your phone and see how fast you brick it.

Using CyanogenMod M9 with Verizon M8 on Tmobile
I have found that this works pretty well for me. CyanogenMod 11 M9 (I cant link to it, forum wont allow me to)

Got International HTC 10 on Ebay, doesn't get LTE on T-Mobile HELP

I bought a new HTC 10 on ebay and it's the unlocked international version. I didn't realize there is a US unlocked and International variants, I assumed carrier unlocked was an international variant. I'm on Tmobile which aparently uses some band that I'm not able to pick up and therefore I've been relegated to hspa for my data. Quite disappointing.
Can I S-Off and change to either Super CID or the TMobile CID and flash the radio and firmware for T-Mobile and get the phone to pick up the LTE so i can get my high speed data?
I can't find anywhere that tells me if the hardware is the same and that the radio is software configurable and therefore can activate the AWS bands with the correct radio/firmware/ruu or something of the like..
Did I totally blow it buying the int'l version of the 10 unlocked, or can I hack it to run properly on Tmobile LTE?

Yes you can do that. Get S-Off, change your CID and MID and flash US Unlocked.

OK. so I did all that and am now running unlocked us firmware. I think I'm having the LTE reception issues I had read about. flashing the T-Mobile ruu should fix that right?

Thanks a million for the prompt replies BTW. I've had this phone for a couple minutes and I feel good to finally get things working like they should be.

I can't vouch for the ruu fixing your lte issues. I've seen mixed reporting around for stuff like this. I would try it and see if it works.

Well, T-mobile has been doing upgrades on the network and there has been a lot of space weather causing power outages and hiccups in other electronic devices. My home WiFi has been connecting and dropping left and right! I too have the T-mobile version of the HTC 10 but I did unlock the SIM and did the full conversion to the North American unlocked developer version and it has been absolutely issue free!! You might want to double check to see if the radios in the International version are using band 12,and band 4 for LTE... I lost my LTE after a long run doing the same thing with the original HTC One M7
I feel your pain

Unfortunately HTC enabled/disabled certain LTE bands in the modem firmware depending on the region. The unlocked international doesn't play nice with T-mobile AWS. Flashing the RUU doesn't change the NV values in the modem, so you'll still be stuck with HSPA for the most part. I'm in AZ, and I can get band 12 and sometimes the non-AWS band 4, but neither are super fast. The snapdragon 820 does support all the necessary bands, they just need to be unlocked. We have the issue that qualcomm has put protection on the LTE firmware, so the old way of using QXDM/QPST doesn't work like it did on the 810 and earlier chipsets. There's some other threads on here that thing a custom kernel might open up the possibility of using the QXDM to edit NV values to unlock the necessary bands.

Verizon variant on AT&T, no LTE even with APN settings and LTE simcard?

The subject says it all, really. I bought a used HTC 10 on ebay. Like many of them, it is Verizon branded, but I had read that it should support all US LTE bands? The model # on it is HTC6545L, sku HTC6545LVW and FCC ID NM82PS6500.
No dice so far. I input the APN settings from here, and that got me from voice-only to HSPA+. No LTE, though.
The sim card came right out of my HTC M8, which is always on LTE at the same location, using the same card.
Could I get it working by flashing different firmware or an RUU?
Any help greatly appreciated.

Whoops, I had assumed I could just use Sunshine but it looks like the only way to S-OFF is to physically mail the phone in to the devs!
Are you certain, that converting the phone is all I need to use the AT&T LTE bands? If so, I can do S-OFF by mail, whatever, but otherwise I might still be able to return it to the seller, dunno.
I guess there's no way to verify without S-OFF, that LTE works?
Thanks very much!

conversion 100% works, and is better served if your going to be using predominately GSM sims... I thought hspa+ was lte though

Awesome, thanks, I hope @jcase is accepting more mail in orders right now.
Nah, HSPA and HSPA+ are kind of "3.5G." You can tell the difference when it displays an H or H+ in the status bar, instead of the usual 4G or LTE icon, and also because it's significantly slower. It does still work in some areas where LTE doesn't, though, and is still way better than 3G.
I was on Verizon when I got my HTC 10, so it's a Verizon branded phone. I unlocked it with Sunshine.
When I decided to switch to Metro PCS which is basically budget TMobile, I changed the CID to super CID, flashed the TMobile RUU and popped in the Metro PCS Sim and it's worked great, wifi calling, etc.
I'm still on Metro PCS but I am currently running the LeeDroid ROM.

Recommended Rootable Verizon Phones?

Hello, I have been with Verizon the last few years and I'm in the market for a new phone. I see on SlickDeals that there is a deal for the Verizon Samsung S10/S10+, but after reading through some of the posts, it seems you can't root the Verizon S10/S10+.
Since I don't need the latest and greatest phone from Verizon, are there any 'older', new in-store models that can be rooted so that I can install a custom ROM, etc?
Thanks in advance!
Your best bet is to get another phone that's not Verizon branded and just activate it on Verizon. You'd be going back a few years to get a Verizon phone that's rootable.
Thank you for this information... a couple of things getting another phone that is not Verizon branded:
- Previously, one would need to make sure they get a 'CDMA' (vs GSM) phone, but is there any technology, etc I need to look for when trying to find a non-Verizon phone?
- I assume if I get a 'non' branded Verizon phone, that some of the Verizon specific features may not work, e.g. WiFi calling, etc?

Thanks for this... that makes sense. The only other things is regarding the Verizon frequency bands - I'm guessing some phones may not have or support all of the Verizon frequency bands.
