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?

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??
I just got an HTC Vivid in the mail today and i have an old Cingular Sim card that's capable of achieving the H+ technology in for example the htc inspire. Now since i live in Portland and there is no LTE yet only H+ why when i put my card in it will make and receive calls and texts but not let me connect to data. Note this is stock ics that the phone was shipped with.
My question is why cant my old Sim work if it can use H+ on my inspire but not on my vivid and also whats different about the newer Sim's then older ones?

The Vivid defaults to using the pta APN. The old SIM cannot connect to pta. You can manually make a legacy APN for wap.cingular or phone which will let you connect, but that's inadvisable.
I'd presume that the reason that a new SIM is required is because you're moving from a 3G technology to a 3-4G bridge technology. I don't know if you have the original Cingular GSM "64k SmartChip", but I had to upgrade that when I first got a 3G enabled phone.

No, that's a 3G-enabled SIM card. It works on UMTS and HSPA, unlike the 64K SmartChip (the GSM SIM) that I had from when EDGE was the best thing since sliced bread. That's why you never needed to upgrade your SIM when faux-G hit on the Inspire.
When I upgraded to the SYNC (see sig), that was right before Cingular was bought by ATT. I had to get a new SIM at that point, and they gave me the one you describe. I had to get another one when I got the Shine, as the contacts on it had corroded (or something; the card refused to read); that time, I got one that said AT&T on it (it was a palette swap of the Cingular card). I was still forced to upgrade yet again when I got the Vivid.
im just going out on a limb here, but i would say it has to do with the apn settings since you have an old cingular sim in a new phone im guessing the apn has been updated for new technology advancements

APN settings are stored in the ROM, not the SIM. The SIM authenticates you with the APNs that it is provisioned for.

I work for At&t, they lie about their data speeds. So basically, the phone might display H+ when your signal is really strong on 3G networks; the OTA updates on the Inspire wanted to make you feel like you were part of the fastest network At&t had to offer at the time. So if you didn't have a 3G sim, you were robbing yourself on speed capabilities, maybe barely but none-the-less. But Cingular SIM cards can only connect to 3G speeds at max. In other words, you're at the max speed for 3G which prompted the phone to display an H+ icon. The Vivid is an LTE capable phone and needs a SIM card with LTE capabilities in order for data to work, even though the new SIMs will also work on 3G, but not the other way around on cingular sims. Oddly enough, you will see a 4G icon when you're maxed out on HSDPA even though you may not be on true LTE networks...as is the case where I live. Hope this wasn't too confusing

I see what you mean everyone yea i actually went in the other day to a store and got a new one for LTE even though there is no LTE in Oregon yet. But i do understand because i did use my Cingular Sim in my vivid and calling/texting did work fine just the data did not work so pretty much for faster internet you need a Sim card that can be provisioned for LTE is what im hearing. Also for the newer tech you need a new one
You can add another APN setting very easily until you can get a new LTE provishoned SIM....THE NEW APN will give you 2g, 3g, HSPA+, Text and Voice....then when you get the new LTE Sim...you can go back and set it to the APN that is named pta....
Let me know by replying if you need the settings for the wap.congular APN and I will post...

Thanks for telling us what many of us probably suspected. I have always thought that most of what we are told is just "marketing hype" until proven otherwise. Much like the burger commercials tha make the subject look soooo tantalizing and huge when in fact it might taste great but is not THAT large.
It is nice to have someone on the inside share "reality" with us!!!
I have a vivid that I've been through hard times with. Went crazy for ics and bricked it for half a month. Then switched to iPhone.. now back to vivid with ics but no LTE. Originally the problem was that I had iPhone imei on the account but not anymore. Just doesn't work unless I use alternate apn settings. Any ideas?

It is likely that you will have to manually setup the AT&T PTA apn (assuming you are with att as you mentioned Vivid and not Raider). The apn is usually the cause for the problem that you mentioned. Do a search in the forum and it will give you the apn settings that you need.
So I did add the PTA and LTE apps. I'm on stock Rom, ics, AT&T. And no LTE. Still. All I can use is hspa+ .
I'm kind of surprised nobody else has this problem. Stock Rom seems full of bugs to me.
I had this problem before. All I did was set up the at&t apn. Applied then turned on airplane mode then wait a little, turn it off. That didnt work the first time so I restarted. Are you in a LTE area?

I actually just bought my Vivid as well from eBay (supposedly new) and it came preloaded with ICS. I wasn't able to get any kind of internet connection with my old Atrix sim even though it showed 4G in the notification bar.
I went to an at&t store and they gave me a new sim and now the internet works but i'm definitely not getting the 4g lte icon or speeds of that nature via speedtest app.
I've tried both airplane mode and pulling the battery, with no results. I'm thinking of doing a hard reset now. *sigh*

Mine came with ICS & showed 4g lte when it is in range. you do need to have an LTE data plan for the apn to work to connect you up with LTE. I figured that one out the hard way. Call them up or browse online for the LTE dataplan of your liking.

I'm also in the bay area as well, within 2 miles of a LTE signal tower. Did you get a new SIM card when you got your Vivid? Because when I went to an AT&T store to upgrade my phone to Vivid, they had to give me a new SIM, because it was running LTE and that would not work if you have an older SIM, which at the time I had. So make sure you asked them for a new SIM card!
Never mind, just re-read the above post, you got a new SIM card. Sometimes it would happen for any kind of reason, I would just walk back into the AT&T store and ask for a new SIM or new Vivid

Yes, make sure you do have LTE specific data plan, as older data plans while work, will not allow you to connect to LTE data.
Make sure they gave you an LTE sim and that switch over the IMEI because my brothers had the same issue
Hi everyone, my network has recently upgraded and has LTE sim cards available. I know the n7000 is not a LTE device but is there any benefit to using the LTE card? Just curious as it is a microsim and I would need to get a sim adapter to work in the n7000.
Thank you for any insight!
Since the Note doesnt support LTE, i very much doubt the "LTE" sim card will make any difference.
But if they are being offered to you for free, take it. its not gonna make your phone self-destruct or anything
my friend has an lte phone. the intenet is very fast but he said he wouldnt buy again an lte phone because its unnecessary.
well when i run it with basic settings its ok but when i add the att pta settings to mine it does run much faster.... you do have to have att's system thinking you have an att note and not the international one. might not be lte speed but mine goes pretty fast...
if you get an LTE sim card in Note 1, you are cued up to get LTE service when you switch your phone to an LTE phone.
I'm thinking of getting one. $9 for the card, I cue myself up for LTE when I get an LTE capable phone. In the meantime, I still get the same quota of 6gb for the same price but now I have LTE.

I wonder how fast LTE is, and network on your country, someday maybe, thanks for reading..
I'm not into lte, at least not now since lte coverage is limited to a few cities in my country (Switzerland) and the prices are still far too high. Maybe in a year or so when the coverage will be better.

Looks like I have wound up with LTE connectivity issues on my 2nd M8. It's defaulting back to 3G and never trying LTE again. I'm in an area where the circuit fallback has already been installed and is up and running, so it shouldn't be that. It randomly just stopped working properly over the weekend. Sprint has told me there are no issues in my area, no work being done.
Is there any chance HTC or Sprint acknowledge this issue with their phones? What is happening under the hood to cause the phone to randomly get mucked up and never be able to get back to normal? Or is there a way to get back to normal?
Profile, PRL updates, rebooting, airplane mode are all (very) temporary fixes for a bigger problem. It acts and feels like a software issue, but is it something that can be reversed or does it get embedded into the firmware, never to be removed? I've tried flashing firmware multiple times without rebooting, over top of itself more than once, hoping to knock out or overwrite something wrong inside. I ran OMJ's h/k RUU last night and it connected to LTE as soon as it rebooted, but today it's right back to where it was.

That may or may not make a difference, two of the same devices in the same location can be connected to different towers unless he uses an app to confirm that both are connected to the same tower and even then I have had experience with two exact devices connecting to the same tower and issues with that tower actually affected one device and not the other and nothing was defective with either device.

I'd say keep a very close eye on them both. My 2nd one was perfect right out of the gate and stayed perfect for 3 weeks, then suddenly just poof it's jacked. It's not as bad as my 1st, but still frustrating. The 1st one wouldn't stay connected to anything, certainly not LTE. Now mine just wants to revert to 3G as soon as it possibly can. Very strange.
My daughter gets very good data with her g2, picks up lte in areas I don't and it gets me frustrated, it sucks I don't no anybody who has a m8 to compare mine with, I'm gonna have to wait till my wife gets hers with her upgrade

I think it's certainly possible but not that common. And if they do behave the same then he's probably ok. If they don't then he'd have to dig deeper.
One store had several M8's on display and the all behaved identical and very different from mine.
I should have 3 of them tonight to compare One being returned to sprint and one that will get sold in the end.
As a sprint rep who lives in an area that sprint spark and bands 2600 and 800 are being implemented I assure you it is not your device, it is the network. This is happening on all lg g2s, g flexs, s4 tri bands, s4 minis, nexus 5s and gs5s. Since the Soft Bank by out Sprint is doing a massive overhaul on their network. Sure service might suck ass for a few months but you'll appreciate it when its done. Hang in there, its more than likely not your device.

I see it daily man. From what I have been told, they had problems with cross connecting calls when implementing spark. Since then, they resolved that issue but then created the 4g data/voice connectivity issue. Meaning when you are on 4g, the tower isn't telling your phone when its receiving a call. Ever wonder why the m8 cannot talk and use data at the same time? However an s3 can. Does that phone have this issue? Nope. Its not so much our phones but more so the towers not communicating to our phone the way they should. This is why when you switch to CDMA only instead of CDMA/LTE, you receive voice calls and texts. Again, you can change this in settings/mobile data/network mode.
LTE only mode works perfect when I enable it. It connects to band 26. Switch back to LTE/CDMA and LTE refuses to connect. The reason I'm confused is because everything worked for 3 weeks straight in perfect fashion. The Sprint rep I spoke to said no work was even being done in my area. @johnnygabe89 can you help me understand how this could be?

Sprint Triband LTE devices do not support SVLTE (Simultaneous Voice and LTE).
In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.
In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.
Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE.
Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones. But the problem here is that the Sprint network is being upgraded in Network Vision, and not all Sprint parts of the Sprint network can currently support CSFB. And it affects all Sprint Triband LTE phones
If yoou want you can read this article all the way thru
I don't think it's a circuit switch fallback issue. This morning I'm connected to band 25 and lte is working. It's when I connect to band 26 that it disconnects. So maybe its not a broken phone?

Well from what I have gathered from all my reading about the issues is that Band 25 is the Sprint Triband LTE, and Band 26 is the older SVLTE (Simultaneous Voice and LTE) and may not support the CSFB and eCSFB yet.
I could be wrong in my assumption
I feel like I remember reading that band 26 is the new frequency 800

I also think it's the network. When I first got the phone, I experienced the 3g of death, but have not experienced it much lately as it seems like Sprint is updating their network in my area.
I'm getting LTE in places now that I have never gotten on my M7.
This weekend, I went to LegoLand, which is a highly congested area, and was getting the 3g off death again, which I believe is related to the network. This is similar to when I went to Disneyland with my M7 last year and could never use Sprint service in the park to due to it being a congested area.
I find it helps to turn off roaming in areas where you get the 3g of death and just connect to the Home network. Try that and see if you get better results. It seemed to work for me this past weekend.
It appears that my area is getting LTE added to the Band 26 800Mhz frequency, though it's not fully up and running yet. So my M8 is scanning and sees that band available, and most likely prefers that band, so it connects but it's not fully implemented yet, so it kicks back to 3G. There was a moment this morning where I had fully working LTE, and lo and behold I was on Band 25, not 26.
If only there was a way to disable Band 26 on the M8 until it's totally up and running...
im facing these issues too..it sucks
