Got a Japan version note 2 SC-02e, after flashing MIUI rom, everything works fine except the phone function. There is no data, no signal, no reception whatsoever. I tried to manually search the service operator, but it turns out nothing. I suspect it may be a problem caused by its unique band. I appreciated any fix suggestion.:laugh:
you might have accidentally unknowingly regretfully ****ed up your imei i.e. ****ed phone features.
before regretting try restoring nand/stock firmware etc.
if you made a backup of your efs then there shouldn't be much to worry.
if not and restoring stock doesn't work, then go to a service center and convince them that you are a innocent cute little guy whose phone was ****ed up in the morning.
Good Luck
Most common mistake for most people or noobs is that they did not know what they are
doing with their devices. Most probably you have screwed your EFS folder.

I hope this isn't too late to help you but are you running the SC-02E in Japan, and if so are you using Docomo or are you trying to use it on a different network?
I've experienced similar problems in the past and in my case the cause there were two separate causes. First of all Docomo Xi phones sometimes have issues when trying to connect to a non-LTE network (such as with B-mobile or softbank) yet often have had the menu options for turning off LTE removed. I had a similar issue when I used my SC-06D with a 3G B-mobile sim (which uses the same 3G network as Docomo) and at first I had the issue of not getting any connection. However after I used a 3rd party app to disable LTE (LTEOnOff) I was able to connect without any issues.
The other cause may be as you said from the unique bandwidths. Japan's LTE network is different from other countries, and traditionally the only common 3G bandwidth used in Japan that is used in other countries often is the 2100mhz one (although Softbank did recently implement 900). Therefore if you managed to flash a ROM for one of the overseas N7105's then it's quite possible your phone is having trouble due to the LTE bandwidths. You could try disabling LTE (as above) and then seeing if your phone connects via the 2100 bandwidth. If that works then then you will probably need to try flashing a Japanese radio (from the SC-02E) to get it to work. This is something that I am trying to get working myself.
For the record Docomo's network runs on 2100/1700/800 for 3G (although 1700 seems to be rarely used) and 2100/1500 and possibly 850 for LTE. Softbank has 2100/900 for 3G and 2100 for LTE. AU runs on CDMA and CDMA2000 technology and thus their network isn't compatible with Docomo's phones.

Can anyone tell me if it is possible to change the HTC from a Euro phone to a North American phone by perhaps changing a chip or programming to support 850/1900 here in North America? I live in an area where 1900 is a bit spotty and I lose signal, especially inside buildings. I love my Uni, but I have too many people complaining that I'm not getting their calls and I don't get signal where other's do.
I'm afraid I don't have enough hardware experience to be qualified to even venture a guess. But shouldn't it be as easy as changing a chip or a crystal or something?
It's just a matter of both the range of the tower you're near, as well as possibly your PRL. The priority roaming list tells the phone who's service you're allowed to use. So if there's a tower within range, but not in the PRL, chances are your phone won't use it OR it will show up as roaming.
I know you can affect the 3G part of Android phones by changing the modem firmware when using Odin, and even them I'm not sure what change is made if truly any. I don't have 3g yet with my provider, which uses the 850/1900 as well, but I currently have a Euro firmware on my phone using XW Euro firmware. I'm not sure how it will affect my 3g until my provider enables it.
Other than that, I think it's a limitation of the radio chip in the phone. It may be a firmware/software setting, or it could be hard coded into the chip.. again I'm not sure
Have you seen the previous post date? lol.
Anyway thanks for your reply
Lol, true it's old, but if anyone has a solution I'd accept it. However, I've since moved on with 3 different phones including the PPC6800, the Omnia II and presently on the iPhone 4.
Thanks anyway,

No it is not possible, it´s a hardware related stuff.

I'm trying out a new TP2-CDMA from Telus (Canada) and this is by far the best system I could ever try in my case. I've always been a GSM user (since 1994) mostly because it gives you the latitude of using what ever device you want just by inserting your SIM card. so I got the Phone Inserted my Rogers SIM in it and it got me on the Rogers network right away I then activated the phone on the Telus network and it is also working fine... of course...
But the best thing is that I set it on "Global" network and it stays on GSM (Rogers), and when I get to an area where there is no GSM signal it switches by it self to the CDMA (Telus) network!!! this is amazing! NO MORE DEAD SPOTS! Of course you need to have two Service contract from two different service provider, but if you absolutely need to get service in areas where your current provider does not offer any, well it sure beats the hell out of having two different cellphone in your pocket... I have set my main cell number to transfer to the other on "No Answer after X # rings" and I get all my calls no mater what network I'm on!
The only down side to this TP2-CDMA Unit is that Telus got rid of a bunch of stuff that is in the TP2-GSM... like the GPS for instance... Well I guess you can't have it all...
Just thought I'd share my joy...
The GPS is working, actually it works pretty well.
rick#2,
You are right, the GPS works.
I was trying it with Google Maps and could not make it work because GM does not seem to be able to get the data connection on the GSM network to load the maps and I thought it did not have the GPS but it does and all other Maps SW works on both GSM and CDMA, except GM that does only work on the CDMA network on this particular device...
I've been using the GSM connection for the TP2 down in the states and I stay purely CDMA up here in Canada. I'd like to say that HSPA works on the GSM network but no dice... unfortunately... don't know why.
Hopefully the 850/1900MHz bands that are possibly physically present on our Telus TP2s can be made available somewhere down the line. It's too bad they aren't up and running now, since I'm headed down to Mexico in a week and they are all 850/1900 down there for their UMTS network.
Yeah..
I know what you mean
Perhaps this one can solve the issues....

Recently moved to a T-Mobile dead zone forcing me to switch providers. As I would like to keep my Defy, I have decided to unlock it and move to AT&T.
Sometime today or tomorrow I will be making the transistion and would like to ask those who have gone before me for some advice...
Preferred ROM for making the switch? (For Example: I'm not sure I completely understand the Bands involved...for a UK ROM, I had to install a patch to get T-Mobile to work, but I don't know how/if it would affect AT&T)
AT&T Software? I can pretty much rip out T-Mobile the software, just not sure about how to get any AT&T specific software I might want/need.
De-branding? Retaining the T-Mobile branded market will just irritate me.
Anything else I should know or prepare for?
Thanks -
Presume you are in the US.
Where I live it's a dead zone as well (for both T-Mo & AT&T) but I use the wifi calling built into the Defy (my wife uses the similar UMA on her Blackberry). The calls are so perfect we could get rid of land lines. AT&T does NOT have wifi calling.
As far as I know there is no ROM that will allow you to run the Defy on AT&T 3G, but I could be wrong. T-Mo is 1700, AT&T 1900 -- both have 2100 for Europe etc. Again, if that's changed someone here will tell you.
I believe roaming -- including data roaming -- domestically is free. That's what I was told by a T-Mo rep, and you may want to double check. But if it is, and you cannot get your phone to work on AT&T's 3G, you may want to stay with T-Mo. Or get a different phone and move to AT&T.
AT&T uses 850 and 1900 and are moving to only 850 which this (US) phone has so it should work in most areas, but I would consider the wifi calling first too as AT&T is much more expensive than Tmo, has data caps and overages unlike Tmo.
Do what you have to do, just be aware of the pitfalls of AT&T.
Thanks for the info. Unfortunately, Alltel was the major roaming provider in the area for T-Mobile, but since Alltel was bought out/merged with Verizon, there is really no roaming in this area any longer.
Wifi is what I am using now, but is extremely limiting, as I am restricted to about 15-20 yards of my living room. There is little to no public WIFI in the area (country living...) and no outside data access though pretty much defeats the purpose of having a smart phone (no Google Maps, remote email, local movie show times, business look-ups, comparison shopping, etc.).
While going with an AT&T phone is an option, I really like the water resistance of the Defy. Since I do a lot of outdoor activities (e.g. hiking) and drive a doorless/topless CJ7 most of year, water resistance is a godsend.
AT&T, while not ideal, is currently my best option.
Does anyone know for sure that an unlocked Defy will work on the 3G 850 freak for AT&T? I recall that some protocols also need to be on a phone for it to register on a specific network.
Looks like this guy got it working on androidforums. Sorry, no links for me yet.

Hi - I'm looking for some good answers - I think I know the basics...
After much shopping, I bought 2 of these...
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170623785892&ssPageName=STRK:MEWAX:IT
(HTC Touch Pro 2 s - the wife likes for our phones to match so I can teach, set up, etc...)
I think they are called T7373 SEA's South East Asia Versions, and I flashed to 2.07.707/4.49.25.91 radio just fine to get current at WM6.5. (I like factory ROM's - the books work, etc - despite my appreciation for the effort to cook.)
Now - I'm currently ATT, and when they go to Data Plan me, I'm going to T-Mobile prepaid.
So - I get to looking at 3g frequencies - of course!
The book for the device says 900/2100 HSPA/WCDMA.
The sellers' ad says
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 or HSDPA 1700 / 2100
(It's not really clear what the 'or' means)
Now, I'm not *****ing at the seller, I want to really understand, and they knew I was US and they asked ATT or Tmobile.
Would they like have reached into one of three bins, to sell me one of three truly different hardware phones - OR - picked a phone up and flashed it (Radio or full ROM) to my provider, or did they just configure the existing system so it picked Tmobile and its freqs for instance? (When the phone boots, it asks T-Mobile or 2 other Asian-sounding systems) How else could the phones do as advertised? (9/21, 8.5/19, or 17/21)
If the frequencies are not a settings, but a ROM/Radio issue, can I load the 'other US guys' flash and have it work?
If not, does anyone know what really is changed in the hardwares (I imagine the antennas' length might vary by X%, but then here that's % of mms.)
Thanks - great answers and experience really appreciated!!
The device in the picture of the ad is a European unbranded model (RHOD100). It's 3G frequencies are on the 2100MHz band. If they sent you the one pictures, you will not get 3G with any US provider. AT&T uses 850MHz and 1900MHz for their 3G service, while T-Mobile uses 1700/2100MHz. 3G radios are hardware dependent, not software dependent. This means that you must purchase the device that contains the radio for the 3G service you wish to use. They will work on 2G networks anywhere in the world. 3G is really the only difference between carriers.
The AT&T device is the RHOD300 model, also known as the Tilt 2. The T-Mobile version is the RHOD210.
The short answer is that if they send you the exact device in the picture from the ad, you will only be able to get 3G in some parts of Asia and Europe.
The description on the eBay listing is just cut and paste from somewhere (like HTC's website), so that is why it says "or" for the 3G bands. One is for the Euro model, the other is for the Asia model. Either way, neither have the correct bands to give you 3G on AT&T or T-Mobile. And as cajun mentioned, bands are hardware dependent, and there is no way to change it.
If you want 3G on AT&T, you need to buy the AT&T branded Tilt2. But since they will be able to read the IMEI number of the phone (since its ATT branded), they will probably add a smartphone data plan very quickly. So its probably not even worth getting a Tilt2, if you don't want a smartphone data plan. If you want 3G on T-Mobile, you need to buy a T-Mobile branded TP2.
Bottom line, if the phones you bought are unbranded, then they don't have the correct hardware to get 3G on either AT&T or T-Mob.
THX
Hey guys(?) thanks, I think I understand.
So - basically the ad HAS to be a lie, at least for 3G.
So I'm still wondering... What does HTC actually change in the phones - a crystal (I doubt this in modern times), a chip, a pack, an antenna length? There is a small area in the phone that looks 'potted' we used to call it.
They are way too pretty, and way too functional 'as is' to mess with (so I'm not gonna go module or whatever shopping), and we are pretty much 'emergency only' web people (for maps, pizza places, etc) and 2G will be fast enough. The value of a keyboard for texting, the Windows interoperability, and no damn contract is good enough.
We are deciding which ROM level we want before we try ATT to see if they know the numbers... T-Mobile prepaid is the backup plan.

A lie in that it looks like a lazy cut and paste, with either no proof-reading to catch the error, or a seller that does not fully understand what he is selling. They are a high volume seller, and also just used stock photos (not photos of the actual item), so its just a rushed auction posting. I don't think it was an intentional lie meant to mislead you. But if you want to dispute the sale, I think you have very good grounds, since the information in the auction is incorrect, and its actually impossible to tell what exact model (Euro or Asian) they are selling from the description.
AT&T most likely won't be able to correlate the IMEI with the right phone brand/model. But I've seen cases where they think its a smartphone, but the wrong one, and try to add a smartphone plan. I read a post where a guy was using a Nexus One, and their system was reading it as a Blackberry. I think he just told them it was an unlocked dumbphone, and they removed the smartphone plan.
Please Correct me if I'm wrong...
presently I'm using Sprint Touch Pro 2, and I have read on the internet that it is possible to work with AT&T or T-Mobile (which uses different technology other than Sprint's CDMA) after proper unlocking. Is it possible?
Regards.

Yes, but you will not be able to use any other network's 3G service. The best you will get is EDGE on another network.
To follow up...
ATT stuck me on $25 Smartphone within 24 hours. (We went to $15 later, and they dropped us to a $10 cheaper talk plan.) For this particular set of phones, apparently the first 8 or so digits of the IMEI is phone type (which they clearly knew from Tilt 2's) and the rest is item serial number. Couldn't argue there...
Speeds, freqs... I don't get a clear definition of G's anywhere, but I show a H before I long on, and another H with bars as I use data. I have used cellular data at up to 1.1mbs per speed sites - I don't know if that's over E, or G, or H but it seems pretty fast to me. All that's on ATT, when I went to the T-Mobile store and tried their card, the best I got was 200kbs on about 5 tries.
Love the phones, added HTC task manager pulldown, and 1.6 VC from here - THX

G stands for GPRS, and it is a 2G service. It stands for General Packet Radio Service. It is the slowest data service you can get with speeds normally under 50Kbps. It is occasionally known as 2.5G service.
E stands for EDGE. It stands for Enhanced Data Rates for GSM Evolution. It was a revision to the 2G service implementation and features speeds from about 100Kbps to 250Kbps depending on location, service provider, and signal. It is occasionally referred to as a pre-3G technology. It fits in the ITU's definition of 3G, but few people refer to it as such. It is normally marketed as 2.9G.
UMTS (Universal Mobile Telecommunications System) was a revision to the voice service, and did not address much data-wise. This was the first widespread usage of the term and use of 3G. It is normally the service that your device is using when it shows the 3G icon. 3G speeds are normally 350Kbps - 500Kbps.
H stands for HSPA. It stands for High Speed Packet Access. It is one step higher than what is commonly known as 3G.It is also known as 3.5G. It features speeds closer to 1.5Mbps. HSPA is normally grouped in with 3G service when it is being discussed.
As for your test with T-Mobile, that wasn't really a fair comparison since you can't get 3G speeds on a Tilt2 on T-Mobile's network. You can only ever get EDGE service. Therefore, you were comparing AT&T's 3G service to T-Mobile's EDGE service. This is like trying to race a Mustang with a Moped. If you get the Rhod210 model, you will get the faster connection with T-Mobile. There isn't much to compare between AT&T and T-Mobile. AT&T 3G speeds are slower than T-Mobile. The services are also much cheaper on T-Mobile.
THX for reply, I generally understood all the abbreviations, but like you said - the marketing hype really seems to very from the technology.
If I saw, regularly, over 1 mbs and the H bars to the right of the H block, do ya' think I was H/HSPA over 8.5/9/19/21 freqs?

On AT&T it would be HSPA on the 850MHz and/or 1900MHz frequencies. T-Mobile uses 1700MHz for HSDPA and 2100MHz for HSUPA. The frequencies for 2G services are all the same for everyone. This is why you will get up to EDGE service with any GSM carrier, but never 3G service unless you buy a device that explicitly supports that carrier's 3G service.
So i recently unlocked my phone, as am in Europe and now, with two different carriers all I've been able to receive is edge on the network. My imei code is still there when i do *#06# and I don't know if I messed my phone up because I cannot test it on T-mobile's network. Any clue one how to fix? The phone is currently running Stock 4.1.2 with root, because I downgraded to unlock. Any help is greatly appreciated.
Have you checked if the networks are compatible with the other bands?

No? could you please provide more info on this?
Look up what frequencies the network providers support for 3g/h/4g or whatever, then see if your device supports them. If not, then what's why you only get edge
Late reply, but this phone is for T-Mobile and Videotron/Wind AWS networks; it will not work on European frequencies other than GSM unfortunately.
European with an American phone here! Been using the d2tmo (T999) for a few years in Europe and it is certainly possible to use data connections greater than edge. I am using 3g all the time and in various countries around Europe (no lte here yet). The problem might have been that:
a) the area where you were did not have 3g coverage, only edge - old cell phone towers perhaps?
b) your signal was too weak - in this case the phone will shift down to edge rather than using faster methods of connection
c) your provider only allows you to use lower speeds (for example in some countries O2 provides first 150 mb of the day at high speed and then reduces the speed by switching you to edge)
d) make sure that you have all network connections enables in settings-mobile networks-network mode. also enable data roaming just in case
I'm no expert in this field, but I have had similar issues before and these have worked for me. Good luck!
