[Q] No data on T-Mobile G2

I got this really cheap T-Mobile G2 in the US which worked perfectly alright and brought it to to my own network overseas. I know the handset uses 3G on a totally different band but I believe edge connection should work, right?
Anyway, I unlocked it using the downgrade method. Then I installed CM7. I put my own sim card and it does pick up signal and I am able to make and receive phone calls but there is no EDGE. I already set the APN options correctly.
Any thoughts?

You sure the APN info is correct for your carrier? Ability to make calls, but no data are pretty good indications of wrong APN.
Yes, as long as the phone has the same GSM bands used by your local carrier, and you are unlocked, you should be able to get data via EDGE.

Isn't there a reason the us has G2 and the rest of the world has desire z? Aren't the bands different between the 2?

Just different bands for 3G. Your G2 has the proper GSM (voice and EDGE) to work in most parts of the world.
And the G2 name is just T-Mobile's branding and to signify the vanilla (no Sense) ROM. The Canada, Europe, Asia versions of the Desire Z all have different bands from each other.

Completely sure. Used the same sim I use in my main phone which is also android based. Could it be a radio issue? I was tempted to flash a new one but since Im not that familiar with this particular phone I don't feel like messing up, especially when all I want is the phone to work so I can sell it.
BTW, anyone interested PM me - although I believe I shouldn't post this here.

[Q] Verizon HTC One AT&T Sim

Hi,
I purchased Verizon HTC One from craigslist it was mentioned that it is pre-unlocked phone. I have used T-Mobile sim and it is working however when I tried AT&T sim in it that didn't work. It shows at top that network is AT&T but I am unable to make or receive calls. I was able to use data on AT&T's edge network ( though my sim is LTE). I know that both T-Mobile and AT&T are GSM networks and this phone is CDMA/GSM. Does anybody else using AT&T sim on Verizon HTC One? Do I have to change some kind of settings??
Regards,

Hello,
I have the same Verizon phone and I'm using T-mobile network, but I can't get data started. What APN settings did you use? If
you could please help I would greatly appreciate it.
Thanx,
SiouxV

You will only get edge because Verizon blocked some of the bands that you would need for hspa speeds.

You will have to change settings to gsm/umts as att uses. Settings>mobile data> preferred network. Also Google att 3g apn settings and edit son. You won't get lte but I don't see why you shouldn't get 3g.

Weird because I have a straight talk att and tmobile SIM card with correct apn's set and I only get edge. I know tmobile reformed my area to the 1900 band too. If I pop those SIM cards in my droid DNA I can pick up HSPA speeds with the same apn settings.

That is weird. I would assume if gsm/umts is an option that HTC would have also included the correct bands but nothing surprises me these days.

I think it has only the 1900 and 800 band. Not the 850, which you also need for 3g. Or Verizon blocked those bands despite the phone being factory unlocked.

There's an app called "LTE On/Off", not sure if can download from play store, but included with certain Roms. It allows you to pick different bands. You can select HSPCA/GSM etc. Maybe this will help with other networks??

I'm not sure. On android central I have a thread there about the Verizon one. A person there says he tried it on straight talk with an att SIM and got hspa speeds. I tried both an att and tmobile SIM card in my Verizon one and only got edge with both apn settings. And tmobile rolled out the new bands where I live too. At the time my one was not rooted so I didn't have that app.

could you flash a new radio? Seems like that might help.. and if the hardware is the same and you get the bootloader unlocked, root the device, and achieve s-off could you re-flash firmware, radios, hboot and rom could it potentially operate as a modified at&t (or other gsm) htc one? sorry if this is completely wrong I'm not a firmware guy.. I know basics of rom's and installations that's about it just throwing an idea out there...

Not sure, but you could unlock your cid setting it to all 1's and flash a gsm edition Rom or ruu, flash radios too. Not sure weather it would work or not depending on the Verizon model hardware but all that stuff you can do.
Turns out the guy on android central was wrong, he was also getting edge data but didn't know it.

Are any of you who are trying to use the phone on AT&T running a custom rom, e.g. Cyanogenmod or Santod's Global Edition?

My one max works on at&t fine once you add the apn settings for at&t.

The Verizon one does not have the same frequiences unlocked that require you to have 3g. The DNA has pretty much similar radio frequiences and gets hspa but the HTC one has those bands locked so you only get edge, even with apn settings.

Great. It's usage like this that was a big contributor toward the unlimited data plans going away. Thanks. This is why we can't have nice things.
Back on topic, I'm curious as well if flashing new radios would do the trick.

They would have to be fully compatible and I'm not sure they would be. Maybe possible but I have not tried. Mainly one reason why they stopped selling the DNA.

So the consensus here is that you cant do any better than Edge service when using AT&T SIM in a VZW HTC One?
See, I just swapped my Note 3 AT&T for this phone, and Id like to be able to use data. I use AT&T prepaid but my Note was always able to pickup HSPA and LTE

Have any of you ever tried doing a factory reset from hboot? That will clear out all of the network settings from verizon, and force the phone to be reprogramed from the sim.

I have, with TikTak Google Plus Edition 2.0, I'm still only getting EDGE data (same as with stock) I have tried using a gsm rom, radio, and RUU. The phone wouldn't start with the different radio flash, the RUU would just boot cycle, and the rom would always fail (status 7, 6, 4).
I have spend about 20 hours on this flashing separate roms, radios and pretty much anything i can find

[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!
Johnny

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.

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?

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?

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!

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.
