I just purchased a rooted Nexus 1 from eBay. It came with Cyanogen 6.0 RC3. 5.08 radio. I noticed it was always displaying an E for edge signal. I went into the phone menu (*#*#4636#*#*) to set it to WCDMA Only. It then would not get a signal at all. I set signal back (WCDMA perfered) and Flashed Cyanogen ROM again with 4.06 Radio. I still get only EDGE. I have another Nexus 1 and it goes between H and 3G (HSPA is active in my area). Does anyone have any idea what could be causing this or how to fix?
One is AT&T band and another is T-Mobile band, perhaps?
No they r for T-Mobile. The problem is it only shows edge and never 3g like it should.

Try flashing back to stock to see if it keeps doing that.
Did you check settings>wireless & networks>mobile networks "use only 2g networks" unchecked. I assume you did since you know the (*#*#4636#*#*) method, but maybe someone else will read this who needs it. If that doesn't work I would test an ATT sim card to clear my curiosity.

Yes I did check this. What will testing phone with ATT sim card do? Phone is advertised as unlocked and rooted. What am I missing?
For 3g, T-Mobile USA exclusively uses the AWS 1700/2100 MHz frequency-band, and ATT uses the 850/2100 MHz band, so a special batch of N1's were made for ATT with different hardware. If a friend's ATT sim card picks up a 3G signal, it means you can't pick up T-mobile usa.
You said the phone was advertised as unlocked and rooted. The thing to check would be to ask if the phone is compatible with ATT's 3G bands or T-mobile's 3g bands. "Unlocked for all GMS carriers" for example, only tells you that it works on all EDGE networks. I haven't seen a Nexus One that can run both 3G networks, but they may exist. (Was there anything in the ad specifically about the 3g bands?)
The ATT Nexus One is more rare, you may be able to sell or trade with someone in the marketplace here on xda or on the internet somewhere.
Sanity check: shut down the phone, take off your battery cover, remove the battery and tell us the FCC ID. It's in the second of three lines of text below where the barcodes are.
My AWS (T-Mobile) Nexus One says:
FCC ID: NM8PB99100
If you have the AT&T version it should say:
FCC ID: NM8PB99110
Note the single-digit difference. If you have the AT&T version you'll want to trade it with someone else who has the T-Mobile version in order to get 3G. If this is the case, you're in luck, because the AT&T version is discontinued and lots of people would be very happy to obtain one from you.

Thanks for the information. You hit the nail on the head! The phone is marked as one of the early AT&T Unlocked models. I also had one of my friends put his AT&T card in the phone and it picked up 3g just fine. I spoke to seller of this phone on ebay and he said he would take item back. IS THERE ANY WAY TO FIX THIS PROBLEM SO THAT PHONE WILL WORK ON T-MOBILE?

hmm...I don't think so.
Take it back to the seller or trade with someone
As many already stated in the thread (starting with me), you have AT&T Nexus, and there is NO WAY to make it work with T-Mobile. But, as also stated, you're lucky - lot of people will probably be happy to trade with you or buy it from you.
I just got a flawless AT&T Nexus One for next to nada $150 from a guy that heads up the IT department at a hospital, he had bought over a dozen f them and I mistakenly thought that since they were Google Nexus devices and since I had a "android data plan" and because I could make and receive calls and get on the web that all was good! What I didn't realize is that I'd be stuck on EDGE for good, they only real downside is that I cannot be on a call and surf the web at the same time, I'm just glad I got a pristine phone that's outta warranty, and running 2.3.6 (stock) and for only $150! Also I've always been a physical keyboard guy, so darn I get EDGE... I run the fastest web on my WEP encrypted network at home and hop on the VPN network at school, and now that the bastards at TMOB don't offer (unlimited) I really don't use alot of data anyways cause I don't goto social networking sites neways!
Any one wanting to trade a TMOB NEXUS ONE for a ATT NEXUS ONE??
Hi all,
I sold my Nexus One on ebay as being "unlocked" and working with both AT&T and T-Mobile. it worked fine for 3G on my T-Mobile account, but the buyer said when he put his AT&T sim card in it though it only worked on the edge network. He pulled off the battery and checked the FCC id number and it is nm8PB99100, which matches the ID number on the box. This means it's the T-Mobile 3G version and not the AT&T version, the AT&T version would be 99110.
He said the 3G AT&T version is the 850/1900 model, which mine was not.
What exactly can I do in this situation? Thanks for any help.
easy, just tell him to switch carriers

t-mobile and at&t use different frequencies for their 3g network.
That's why Google has a T-Mobile version of the N1, and an at&t version. The t-mobile that works with t-mobile 3g, does NOT work with at&t 3g. And vice versa. The guy is screwed and can use at&t edge network, but not 3g.
He is not screwed, I've been using the t-mobile version on att for about a year and it's not to bag. I use wifi at home and at work.

I think the he's screwed referred to his desire to get 3G reception on AT&T with a T-Mo Nexus One.
You can ask for your phone back, refund the buyer and know your facts next time.

The phone IS unlocked. Meaning it works with Tmobile or ATT. So you did get it right there. Just like the others are saying. Tmobile N1 wont work on ATT 3G and visa versa. If you never stated that it will work on ATT 3G in the beginning i dont see it as your fault. The user should of asked questions prior to buying the phone. Unlocked doesnt mean it will work on both networks 3G's service. Unlock just means the phone will work on any network with a SIM.
Unlocked means that it is not locked to a specific carrier, not that it will work on any network. Depending on your area a tmo phone may or may not be able to ride 3G. In my area it would be edge only. If you said the phone was AT&T compatible for 3G your description was incorrect, a compatible phone would support both 850 and 1900. If you said it "might" work on AT&T, area depending, then you were honest as far as a court date would go. Were it me I would offer to refund so long as the buyer payed shipping regardless of how I worded it. Usually you have to suffer to do the right thing, in this case you can do it for nothing.
thanks for all your help guys, he sent it back and i gave him a full refund and posted it back on ebay with the correct information.
is there like a software or root, rom etc that can fix that promblem

Nope. I think they tired to do that before on the G1, but finally gave up and said it was impossible.
Noo because it is a hardware issue.
Hey all,
Hope this is in the right place. Saw a few similar questions, but nothing exactly like what I was looking for.
I currently have a VZW Galaxy Nexus, rooted, running Shiny ROM with Xposed and GravityBox. Thinking about dumping VZW and going to a Moto X on AT&T or TMO, both prepaid. Question is, which carrier's phone would I be able to use outside the US? I'll be going to Europe this summer and would like to purchase a local SIM in Europe and use it there, instead of paying roaming fees on AT&T or TMO.
According to Wikipedia (can't post link) and what I've read on here, the TMO version is SIM unlocked. So this means it will work on all GSM carriers, right? In the US, that would be AT&T (if TMO doesn't have good signal where I live), and when I travel, that means I can use a local SIM, correct?
Thanks in advance, any help is appreciated!

Yep, that's correct. T-mo is SIM unlocked. I use mine with AT&T actually too. It should work abroad with no trouble other than tracking down a local nano sim or cutting one down.
If however you want to use LTE abroad I don't think the bands in the T-Mobile version match those used in Europe. HSPA+ should work fine though.
From my experience when traveling abroad a prepaid SIM w/ LTE was way more expensive than something I wanted just for being able to gchat home and look up directions on gmaps so it was a moot point.

Thanks, that's exactly what I was looking for! I figured LTE wouldn't work in Europe, I was fine with settling for HSPA+ or 3G.
Found a thread here explaining the differences between AT&T, TMO, and Dev Edition. From what I can see, the TMO edition is more flexible than the AT&T edition. Only difference compared to Dev Edition is that unlocking the bootloader on TMO voids your warranty.

LTE works in Europe although is not yet as widely spreaded as in the USA. But you'll be fine with 3G which is fast enough and most countries are well covered with that network. More important issue is roaming if you are planning to visit different countries. You must switch between different operators and even using service from the same operator in different states ( e.g. T-mobile) imply roaming charges. In my opinion the best solution is using local sim with best data plan and voip for calling in every country. If you don't want to switch sim cards, you may find the best roaming solution with prepaid Vodafone Italy. You can buy its clone online (http://www.motorhomewifi.com/product/europa-sim-roaming-data-sim-card/) and refill it in any Vodafone shop around Europe.
Hello everyone,
I want to to know exactly how I can implement this to my HTC one however what I've been told is that what ever Sprint devices they have sold will not able to work on this new upgrade.
I've been chatting back and fourth with an employee and he says it's a gsm based 4g LTE that's works on hspa or something that uses 1900mhz bandwidth. With that said will I be able to go ahead and convert to what my carrier uses?
Another note, I've successfully SIM unlocked but haven't had a SIM to try it out if it is unlocked, in doing the unlock will I be able to utilize this update to my carriers data speeds? All the employee said as of right now Sprint branded devices are not able to be used with the upgraded network and it uses a gsm based 4g that uses 1900mhz bands. Quite a few people are pissed about this but their normal users and do not know about root and everything associated with it, to include SIM unlocking.
Another thing the employee mentioned was they are now selling HTC one m7 and m8 that are able to utilize the network, he says they are "generic" and Verizon, what I'm thinking that they are just global versions of the device, so who ever got Sprint branded phones are screwed cause they can't upgrade to the new network.
I am hoping I can use this new found boost in data speeds locally!!

County? City? State? You provided no information here. Also from the sounds of it NO you can not convert your phone. The bands 4G uses are limited by the hardware in them, if you bought a SPRINT CDMA phone in a foreign county no one screwed anyone except you screwing yourself. You should have bought the global version directly from HTC.

Thanks.
I'm not in the states I'm located in Guam, I'm aware of the hardware limitations, but I'm wondering if the device will be able to pick up signal. I believe my carrier will be using hsdpa bands at 1900mhz and I'm under the impression that the Sprint use those
I am screwed as well as others that have gotten Sprint branded devices here, I feel for them but those people are normal users, that don't know rooting and what associated with it. I don't feel too bad about having this device at all, it's been working great, I was just waiting for my carrier to bring out something 3G data.
I was really banking on having it be able to get the upgraded speeds, and maybe help others who are on the same boat as me.
Thanks again!
Hi, I was wondering if an unlocked Sprint LG V40 is good for any other US carriers? any band restriction? Many Thanks.
As far as I know I have the full V40 ThinQ LM-V405UA network unlocked and factory unlocked version and it works well with ATT and T-Mobile as well with sprint am not sure if it will work with Verizon because as you know Verizon and Sprint do NOT like to support each other's phones even though they are in most cases IDENTICAL in every way.
I did do a check on verizon BYOD site and it says Mine is NOT compatible with there system as I had guess it would say that.

Hi Zxhwk, do you know if T-Mobile Wifi Calling is working and do you get full 4G LTE speed on T-Mobile? I don't know if there are some bands missing for T-Mobile 4G LTE.

I'd really like to know this as well.
LM-V405UA is way cheaper used than a LM-V450TAB!
I'm using unlocked sprint with Verizon network, works fine except advanced calling when you use your data together with the call. Spring uses different technology for that which does not work on Verizon. Also voice mail notification does not work. Otherwise no issues
Can the Verizon image be flashed to the sprint hardware (which appears to be identical) to get the Verizon advanced calling features?

Yes you can flash the Verizon KDZ
Can I replace the motherboard from a Verizon or AT&T LG V40 with a T-Mobile one? I ask because the T-Mobile LM-V405TA can't be rooted and it would be cheaper to buy a motherboard than a whole nother phone.
