[Q] factory reset

hey guys quick question
i brought a at&t nexus1 off ebay. the seller mentioned it will can and only work on tmobile 2g [i am t-mobile],
my question is if i factory reset/wipe the nexus1, does it lose complete compability with tmobile?

Factory reset only wipe data. you can still use the phone with tmobile
and still 2g only

so flashing roms, kernels, recoveries and all that good stuff, in the end i will still be able to activate the phone aka [ google sign in at the beginning activation ] with a tmobile sim card?

Yes. Just keep in mind that you'll need to stick with american firmware. With different ROM, you can even use 3g, but it depends on you provider too.

He will not be able to use 3G on Tmobile no matter what ROM he use.
The 3G limitation is a hardware issue.

Really? How so? Nexus One do support 3g. Isn't it matter of installed modem? But maybe T-Mobile has modified it somehow on hw basis...

There is two version of Nexus 1, one made for Tmobile frequency and one made for AT&T. While they are both sim unlock, you can put sim card from either carrier into the other and it will work as far as phone calls. For 3G support a Tmobile sim in a AT&T N1 will only work with 2G not 3G.

I suppose that it is only T-Mobile's fault, not phone's. Phone itself do support 3g, and I do suppose that T-Mobile has just disabled 3g on the SIM or on the modem's side.

How is it T-mobile's fault? Their 3G work on a certain frequency. AT&T 3G work on a certain frequency. If you buy a phone that does not work on your carrier's frequency, it's the buyer's fault*.
*Nothing against the OP in this post. He knew he bought a AT&T N1 and know 3G don't work on T-mobile.

yeah lol i dont even have data on my phone, so 2G / 3G doesnt even matter to me,
im just worried if it i factory/hard reset the phone, that the phone will "lock" back on AT&T.
but imo, since the N1 is carrier unlocked by nature, it will stay that way no matter what i do right?

correct, factory reset will only wipe data. out will not get lock into any network.

True. So then we are back at my first point - wrong modem. It can be easily reflashed without loosing any data, so Nexus will operate on frq your provider uses.

You cannot change the operating frequency of the phone - it's a hardware limitation.

Maybe if you flash a new modem it can run on Verizon.

It'll be good if you actually read before making false statements and insisting on them.
Read the FAQ, question 13.
Nexus has 2 HW variants, with 2 different sets of 3 frequencies for each variant. The variants differ in HW and use exactly the same SW, including modem.

Working Everything (NEEDED!)

Hi guys I'm new here to xda. Recently, I've just completed rooting my HTC one and s-off. I currently have the eclipticone rom installed but have NO DATA. Once I turn off the wifi I can't do anything on the internet or receive emails. Is there any roms out there for the HTC one with working everything for sprint?

Hi,
Maybe it's better to take a look here: http://forum.xda-developers.com/forumdisplay.php?f=2215 ?

I think I saw a download for Sprint on PAC ROM , but I may be mistaken. I would first look there and then maybe look at the CM ROM. Good luck.

You did something wrong. Ecliptic in the Sprint forum is 100% working. As most of the ROMs are.

Good news everyone I've solved the problem. Some how my radio signal was set to LTE/Cdma. Sprint said when set to this it trys to pick up LTE or 4g first before picking up cdma.

Would you mind telling me where you are located geographically? I too recently discovered this setting must be set to CDMA only in my area. It's SUPPOSED to connect to 3G when no LTE is available, but for some reason that's not working in my area. And this is a very recent change. About 12 days ago I lost data and it took 3 or 4 days of reboots, reflashes, and phone calls to Sprint before *I* fixed it myself by selecting CDMA only. Sprint never bothered to suggest the change because it's not supposed to matter. I'm baffled by this so it occurred to me you might be in the same area as me.

Would you mind narrowing it down a bit? Are you in one of the areas served by nTelos? In central and SW VA, there are many areas that do not actually use Sprint towers. Sprint has some sort of partnership with nTelos and I happen to live in one of those areas. I have seen info that indicates nTelos will begin rolling out its 4G network in the latter half of 2013 and it occurred to me that the sudden necessity to set the phone to CDMA Only might be related to the early stages of this roll out. Almost as if they have started the process and are transmitting some sort of partial signal that makes the phone think there is a valid 4G connection, which therefore prevents it from looking for a 3G signal. I may be grasping at straws, but after switching to Sprint 3+ years ago on the promise of "the nations first 4G network" AND paying an extra $10 for the privilege, I would REALLY like to finally have access to something better than Sprint's abysmal service in Charlottesville. :crying:

Your towers may be broadcasting CDMA eHRPD (basically EvDo with an extra layer to help handoff between 4G and 3G). I discovered that with the SIM card in my phone being defective, I could not get data from any towers in my area even on 3G. This was confusing to me because I thought that the SIM card was only for 4G data. When I went to check the network type under the about area in settings, it said CDMA - eHRPD. When I switched my phone to CDMA only, the network type changed to CDMA - EvDo Rev A and my data started to work.
If you are using a phone with a broken SIM this could be the problem. My phone did tell me that the SIM card was not detected though, so I knew it was a problem from the beginning. Your issues could be with the towers in your area instead if your SIM is fine.
Also, there are rumors that Sprint may overbuild into nTelos territory since nTelos was not being obedient to Sprint's demands in rolling out NV at the start. This would be good for me as I travel up central VA once a year or so

Very interesting, thanks for the info! To cloud matters even more, the ROM I'm running right now, a 4.2.2 Sense 5 concoction, doesn't even *HAVE* a CDMA Only option.
And you're right about eHRPD, my phone is reporting that as well. Funny thing is, even without the ability to select CDMA Only, I'm having no problem at all with data now. Oh and one more thing that may or may not matter, I flashed a hacked PRL that forces roaming on VZW, so maybe it only works because I'm not even using nTelos' network at the moment.
All I know is that I want Sprint to get their $hit together in this area so I don't have to jump through hoops just to get reasonable service.

T-Mobile 4G vs LTE with Moto X?

Have had LTE in our area for years just noticed the other day both Moto X phone connecting on 4G?
Only setting I find is Auto and or 2 G
Under settings, Data, other, mobile network, preferred network type.
I'm I missing some other setting or trick ?
LTE is checked in APN setting

Change back LTE to unspecified. Make sure you have the LTE APN and the dot beside it is highlighted.

If my memory serves 4.2.2 only showed 4G. 4.4+shows 4G with a small LTE above it. Ignore my screenshots cause my signal bars are modded. Here's what your APN settings should look like...
I can't attach screenshots for some reason...
I'll try and upload them when I get to a PC

Or I could just clear data on the XDA app and post them now.

Guys it's requirement from carrier to show 3G HSPA+ as 4G you can download LTE on off app from play store and try setting LTE only to check whether you are getting LTE signal it should show 4G LTE icon

Did your phone update overnight? If you're stock you might have gotten 4.4.3

Upgrade was done Sunday it was doing this prior to 4.4.3

Which international version is best for tmobile?

I was thinking about getting an international phone but there are a few versions N930F/FD/S/L/K . Which would be most compatible. As I understand it, the downside is missing some of the bands for data. 3g is the problem I think. Can anyone confirm this or input any additional issues.

N930F/FD will definitely work on T-Mobile...
I think WiFi Calling and VoLTE won't work and you might miss a band or two but it will work just fine.

Isn't WiFi Calling a built-in feature of Android 6, now? I use it on my Nexus 6P and it has no T Mobile software at all.

I believe 4g is ok. The some bands for 3g have reduced speeds.

N930F has all Tmo bands. WIfi calling and VOLTE will not work with stock rom, but will if/when custom roms come out.

Did anyone go this route? I see couple for sell on ebay.

Very odd as both worked in the S7 FD version I had for a bit. The requirement isn't bands but that the TMO sim has to be in sim1 not sim2. If it's in sim1 then both work. Also, VoLTE is hidden and always on if supported.

I have achieved 3G thus far, I've heard folks can get full 4G LTE, Maybe it's as simple as calling Verizon Tech support and they can assist me somehow. Was hoping I'd get some real help here on good 'ol reliable XDA first and foremost.

This phone isnt compatible with Verizon's 4G LTE. it does not possess the necessary band to achieve this.

You can set the phone to LTE only and get 4g data but no calls or text. Or you can go the regular way and have 3g data calls and text. Sadly not both
