My Tmobile MDA is showing no signal after i unlocked it with the special edition rom. It doesnt seem to be able to read any network in my country. A few minutes ago i just had an idea or it jus toccured to me that maybe its the band. please is there a way i can choose bands on the phone!!
I think we use 1800 in nigeria.
You can choose band by pushing reset while pushing power, once entered bootloader push button below antenna, choose your band from there. This may cause a hard reset so backup first. Are you sure your phone is capable of 900/1800? Some phones are 900/1900. If you look on the label it should be PW10A1 for 900/1800. if it is PW10B1 then it wont work on 1800 band. Even if you choose 1800 band in bootloader menu it wont work unless label shows 10A1.
thanks alot. I kind of found out how to fix it about 5mins after i sent the post. :?:
I bought a new att 8525 about a month ago it came with an ATT 3G sim card
I have a Thailand phone and SIM card(the network is AIS)with international roaming. Before I bought the 8525 when i would be in the U.S., I would just use my thai cellphone, an old tri- band nokia and when in the states It would automatically conect to Tmobiles' gsm network(1900 frequency I think)
On the 8525, The phone was locked of course so that the thai sim would not work. I ran Pof's program Auto unlock v3a. I put the AIS sim back in the phone and it worked and automatically conected on Tmobile's gsm network . I was exstatic!!!
Then... I caught a plane back to thailand. While between planes in Taipei I turned on my phone with the Thai sim and it connected !!! I was still exstatic!!!
THEN...I landed in Bangkok thailand. Turned my phone on and it will not recognize any netwoks other than some weird 1900 gsm network that I have never heard of. It does not recognize either AIS or DTAC or Orange which are the big three in Thailand.
I took my Thai sim out of the 8525 and put it back in my old nokia phone and it immediately conected to the AIS gsm network.
So it appears my new 8525 phone is not recognizing 900 and 1800 gsm networks. Pof's program definately ulocked the sim because it doesnt ask for an unlock code. I read the NO gsm issue but I am not sure that is this issue because the phone does appear to recognize 1900 gsm both here and remember it did conect to Tmobile 's 1900 gsm network in the states.
So the issue is recognition of 900 and 1800 gsm.
What can I do? Can someone please help?
Thank you in advance
Here are my device info after runing pof program, I am not sure what the info was before I ran the program:
ROM version: 2.15.502.3
ROM date: 04/09/07
Radio version: 1.16.00.00
Protocol version: 32.53.7018.01H

Have you checked to see what is enabled under the bands tab in the Settings > Phone panel?
Possibly, something is disabled there. It is possible that you have a resricted setting. If you do not have the "Band" tab visible, the registry hack is in the wiki or certainly somewhere. Try the google search link in my signature.
registry tweaked to add band tab but still havea problem
Thanks for the advice.Sure enough the band tab was not visible so I tweaked the registry to ad the band tab.
However when I try to change the gsm band from"auto" to 900/1800 I get a messsage that says :
"Warning unable to change gsm/umts band, please try again later."
regardless ofhow band setting are changed, auto./gsm, my phone still only detects the 1900 gsm band. arrrgh!
I have since my last post also updated my radio to 1.50,still nothing.
any elpis gretaly appreciated.

"Warning unable to change gsm/umts band, please try again later."
This ussually means there's a live connection somewhere. Make sure your disconnected from gprs, internet, etc., then your manual band changes will take.
thank to everyone that makes this forum possible
Problem solved after i shut down the phone, inserted my att sim, then phone all of a sudden starting recognizing all the 900/1800 networks here(asia/thailand). I then shut off the phone, inserted my thai ais sim and it also started picking up the networks. Not sure why I was geting the warning message .If it is due to having a live conection somewhere, my gprs was not configured on the new phone yet for thai/ais simand would not connect.
Anyway thanks you all for this forum.Now I will read , read read some more on the best 6.0 ROM for my phone.

Vodafone requires that a new Access Point Name (APN) be set up for the SIM. The problem is that the Photon won't let me me create and save a new APN. What I've discovered is that, if I set the MCC and MNC in the APN to Sprint's values (310 and 120), then I can save the newly created APN, but the data connection won't work. If I set them to the appropriate values for Vodafone (505 and 03) then press save, the newly created APN disappears.
I spoke with Sprint today, and after 40 minutes of getting bounced around, finally got to someone who told me that this was by design. So if true, it appears that the SIM is unlocked for voice but locked for data (at least, if the carrier requires specific APN settings, as Vodafone does).
I also tried using APN Manager from the Android app store to create and select a different APN - no dice there, either.
Any suggestions, or am I out of luck?
The good news is that I brought my trusty old Touch Pro2 with me, just in case, and it is working fine ... but going back to the TP2 after a blissful week of using the Photon is really, really hard.
Doesn't make sense to me that it would only be unlocked for voice and not data. Did you try contacting Motorola directly? I'll rather hear it from the horse's mouth.
It's hard to tell who's really the horse in these situations ... nonetheless that is a great suggestion, and I've just submitted the question to Motorola's support site.
Im sorry...im very confused by this. Ill be traveling to lebanon tomorrow and specifically got this phone to be able to pop a sim in and use data and voice....your saying i wont be able to uze data?

I am saying that I can't use data ... your experience may be different. I suspect that this may work for some carriers but not for others, depending on what settings they require for data. If they require you to create a new Access Point Name profile, then it most likely won't work, given my experience.
I'm able to use data on a foreign sim. I was able to save the apn also. This is with Telcel and Movistar in Mexico. Setup the same as my Samsung Captivate.
So is there any possibility that this thing would ever be unlocked for US gsm networks like the Touch Pro 2 was? That would make this unit epic....

Which carrier did you purchase the phone from - was it Sprint?
So here is the latest, for anyone who's interested.
I emailed Motorola asking about why I couldn't save the APN, and was told
Motorola does not have any access to the Access Point Name (APN).The APN can only be access or generated from the service provider.
I then contacted Sprint again, and got a hold of someone who took my request more seriously then the previous Sprint people. After several days, however, this person came back with
I contacted Motorola and was told that the data will not work with the Motorola photon gprs data
I have no idea what the truth really is, but the bottom line is that I could not get the phone to work with data using a Vodafone Australia SIM. I even had Vodafone replace the SIM with their most current SIM - didn't help.
My Touch Pro2, on the other hand, had no problem getting the SIM to work for both data and voice, and I ended up turning my TP2 into a wireless router so I could indirectly use my Photon while out and about.

It's been a while since I was in Australia, but if I'm not mistaken, Vodaphone operates data on UMTS 2100 down under. The photon is tri-band, not quad-band, so you're not going to get data with a Vodaphone AUS sim. Virgin Mobile in AUS operates their 3G network on 2100 AND 900 MHz, so that would be an option. Another one would be Telstra. A SIM from either of those providers should work, giving you access to the APN settings. They remain grayed out until the SIM can register with a UMTS data circuit on the required radio band.

It depends on where he is in Australia. In most areas Vodaphone's network operates on UMTS2100 which the Photon does support. In some smaller areas it's UMTS900 which the Photon doesn't support.
Is it possible that the SIM card is supposed to "provision" your data similar to when you activate the phone on the Sprint network initially?
Or is the creating of an APN always a manual program effort by the user?

This is a good point. It's entirely possible he's in a UMTS900 zone...

This is from Motorola's site:
NETWORKS4
Worldphone - WiMAX 2500, CDMA 800/1900, WCDMA 850/1900/2100, GSM 850/900/1800/1900
I believe WCDMA 2100 is the UMTS band being referred to. I am fairly certain the Photon is a Quad-band true world phone. http://www.motorola.com/Consumers/U...Mobile-Phones/ci.MOTOROLA-PHOTON-4G-US-EN.alt
EDIT: I see now you meant UMTS on 900 MHz rather than GSM at 900.

It sounds like the guy is having APN issues, not reception issues. Otherwise he would have at least been able to get EDGE/GPRS connections - but those too require the APN.
FYI, I was in Sydney for most of the trip, with a few days in Canberra.

I started two threads on the official Sprint Support forums. One in the normal Moto Photon, and one in the Premier area. Wonder if Sprint will respond.

Yes, it's ridiculous that Data and voice are so segmented, but these are smartphones! Gone are the days that you just had to worry about the GSM voice frequency. Now you have to make sure the data frequency and radio band are supported by your phone.
For what it's worth, I've had little luck with Vodaphone sim cards overseas. I typically use Tmobile or Orange sim cards in the UK, and TIM or Wind in Italy. For points in between, I just roam on the UK Tmobile sim. Next trip won't be for a bit, so I'm eager to see what the photon is like...
did you try rooting and manually editing the apn database with SQLite?
This was taken from the atrix APN editing thread:
Code:
2) Enable Airplane Mode
(hold power button for three seconds, select Airplane Mode)
3) Open Root Explorer
4) Navigate to: /data/data/com.android.providers.telephony/databases/
5) Click on "telephony.db"** (this should open the db using SQLite Editor)
6) Select "carriers"
7) You should see a long list of APN settings for various carriers. Edit/add what you want
8) Press back twice to close the SQLite editor and you should be back in Root Explorer. Close Root Explorer.
9) Disable Airplane Mode
So Just add the APN with the sprint MCC and MNC, then manually edit the APN's MCC and MNC and see if that works
I bought a Note ii clone from China http://www.dhgate.com/product/1-1-n7100-note-2-mtk6589-quad-core-android/160552013.html It states that it has850/2100 WCMA 3G bands, and i am on Virgin mobile in Canada which is a WCDMA network only that uses 850/1900 and LTE thus i figured it would work. I put in the SIM card and the phone right away told me my phone number and that it is a Virgin SIM i was extremely happy. Yet it said no service when i asked for the phone to connect automatically it said can not connect to network now please try later. When i searched manually it cound Virgin 3G and then again when i chose it i got the same message! I have factory reset the phone and have restarted it taking the battery and SIM out. I have downloaded Mobileuncle and it states the phone actually not only has the 850 but also the 1900 WCDMA bands, now i am baffled. Am i doing something wrong? why is it not working? I have it set at auto gsm/wcdma for preferred and nothing. I did try the second SIM slot with a Rogers SIM and it worked for GSM as the second SIM is only GSM, Also in unclemobile under engineer mode>engineer mode (android)> phone information it states the phone is on GSM auto (PRL) and i have changed it to different settings, but they wont stick, every time i change it get out and come back the GSM auto (PRL) comes back, any way to fix this to WCDMA preffered and make it stick? Is this the issue? Since 2 days ago Canada has a new blacklist for stolen phones i checked the list just to make sure, but the IMEI number isn't blacklisted.
I have input all the info. i know and things i tried, if anyone can help with this or have any suggestions i would be grateful!
Thanks in advance/
Haven't seen any post on this, but I got AWS working on a Bell LG G2(D803)
Added band support using QPST and connected to Wind no problem.
Care to share your method?
I roughly followed this: http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
No need to root the phone, it goes into diag mode when you set the usb connection to PC mode.
I used 115868544 as my NV value. Not sure if you can add more bands but AWS was the only thing I was interested in.
Hi, I have tried Googling this but I still don't really know how this works.
I have a D800 that offers LTE 700 / 850 / 1700 / 1900 / 2100.
However, I need LTE 1800 for 4G in New Zealand.
Since Snapdragon 800s have modems on board, can I flash the bands for D802 and get 4G?
I don't really know about this so please help.
Thanks
I didn't mess around with any of the LTE bands, only the WCDMA bands.
I have tried changing WCDMA and LTE bands on my VZW VS980 being used on ATT network.
After several attempts, under different Roms and Kernels, I have been unsuccessful in changing either.
1877 NV value can be changed but leaves phone unusable while 6828 NV value changes do not stick after reboot.
If anyone has been successful in getting VZW branded G2 activated on ATT, please let know.
Here is a thread that has lot of information... Most of the changes, I found are reversible. So go at it...
