I been following the Global capabilities threads on the Rezound for some time now.
I recently visited Chile, where GSM operators use 800/1900 gsm.
I took both my Rezound and Droid 2 Global.
I was able to get voice and data working on the Droid 2 but only voice on Rezound.
Other threads have tested that data only works on countries that use 2100mhz gsm.
Last week I loaded the leak 4.0.3 ICS on my rezound.
While fiddling around with the phone info screen, I noticed that you can press menu and you have a new option available, that lets you select GSM bands for different parts of the world.
Unfortunately I did not have ICS while in Chile so I cannot test it, but can anyone outside the country with the latest ICS load be able to test this for us?
There is even a USA option on the GSM and screen. Maybe a way to make it recognize ATT or TMobile
In any case, dont forget to set the correct APNs for the SIM card you are testing
Also, I am not using any custom ROMS, just the leak that will be push out to Rezounds next week
Go to phone info, press menu, select RADIO BANDS
I found this today when i got my phone back from the dead lol

Tried to change to Euro band, said unsucessfull but I no longer lose signal when trying to send a txt (txt is not sent though)
Lets hope that the final RUU will get an update that upgrades it to a global phone

Yes my carrier uses the 2100MHz band so it's working out of the box. Plus WCDMA option sticks in every reboot
is there any custom ROM available witch support 800, 900,1800 or 1900 band.
i am using BSNL 1900 band in in India , but no luck with data.
i also checked with 2100 band , data works fine.

Hey guys... I just picked up a
SGH-i717
v 4.0.4
Black Star V LF6
LTE Sim, LTE phone, downtown Toronto
I just picked the phone up on the weekend.... It's my first unlocked phone and my first rooted phone. I can't seem to get a network connection (I'm with Fido).... initially I tried a number of APN settings as I browsed through various threads on APN settings for Fido, Android and Galaxy Notes. Over the weekend I had connection of approx 1 to 2 bars, and was at least pulling light bandwidth off the edge network. I called Fido last night to have my network settings reset, and since them I haven't been able to get on my network. It seems to jog between no connection, 1 bar and 2 bar signal strength. Where before it said it was on the edge network it now does not connect to a network.
Calls to Fido show that everything is set up ok from their end; they can't support a non-Fido phone, and they say that they can't guarantee I'll get more than 2 bars connection on any non-fido phone. I was making calls & texts from the phone on the weekend whereas now, following the network reset from Fido, I have no connection. Yet when I Reset to Default the APN settings it populates the fido LTE apn without issue.
I'm lost... could someone please help me out here? I have no experience with either rooted phones or unlocked ones... and my furious googling and thread browsing just seems to be hitting the same recycled threads.
'
Where I'm left is now it's saying 'Not Registered On Network' regardless of the APN setting I use.
You need to check your baseband, or modem. And verify you have the correct one for the fido network.
I Dont know which radio image is going to work for you, but it sounds like the rest of the device is fine.
Check in the general section, and open the "super everything" thread.. There you will find many solution threads, and possibly the correct radio image to get your device running properly.
Radio images are almost always a .zip file that is flashed in recovery. and they are very easy to use. You simply download the image you want to try, and place it on your SD card. then boot into recovery and flash the file....reboot, and test.
You should read up on the flashing method too, and ensure that you understand exactly what you are doing "before" making internal changes to your device.
Additionally, you should make a nandroid backup of your current rom, just in case something goes wrong. then you have the ability to restore the old build and get the phone running again.
read, read, read....it's the only way to grasp this information...
good luck.....g
Thanks gregsarg, that's a great start for me. I will throw myself into that direction. Thanks again for your help.

Well, a slow evening with little progress. After reading much, I ran a backup and tried installing a radio...no error message, just says installation aborted... not sure what tdsp is but I tried downloading and installing goo manager as I read where CWM (which is what I.assume I have now) doesn't work that might, but the installer which was supposed to have rebooted my phone and installed, it did not. This was a good 3 hrs and I was spent for the night. Guess I'll keep plowing away tomorrow.
I created a TWRP backup and have begun flashing different radios/modems... When I try to access mobile networks with the different radios installed none seem to work... .... so far I've tried:
Blaze_4g_LB7_radio_ATTNOTE
icsblaze
ROGERS_MODEM-CWMXLA2
UVLG3modemfori717
VK1_Test
KID_TEST
I've always wiped the dalvik/cache before flashing a new radio. My baseband was i717UCLF6, but after I restored it's now T879UVLG3, which is wierd because UVLG3 was the last radio I installed before I restored. I assume the radio didn't restore and I'm now using a T879 radio as opposed to an i717 radio, but it does not prompt me for a sim card after the restore. I can select a preferred band using the *#2263# command, but none seem to drive a better signal - I'm still idling somewhere between a no-signal and unknown network (most of the time) and 1 to 2 bars. Some of the above recognized my sim and suggested either HSPA, GSM, etc on the *#2263# command, others showed nothing when I did that.
Am I correct in assuming I just need to keep doing this until I find a compatible radio and upon flashing and rebooting it will simply connect with a solid signal? Is there any more specific versions of radios I should be targeting?
Re: SGH-i717 No network connectivity
The modem isn't changed or restored when you restore a nandroid or flash a rom.
If your goal is t-mobile or wind or simplemobile. You have the correct modem installed.
Just go to settings and input your APN and save it. Not every rom has the apn's , and not every carrier automatically sends the apn settings.
Thanks Ranger... my goal is to get it working with Fido... but I'm not sure if that's synonymous with T-mobile or Wind yet
and ngretud
Anyone else have any input on Fido radios? I can seem to find one that works for Ontario....
consistent tomsisu
I've now tried the following radios:
ICS Kid
ICS Telus
ICS.zip
ICSblaze
Kid_Test
UVLG3modem
VK1_Test
Every single one upon reboot leaves me with no connection.,, I don't get what I'm doing wrong here... frustrating. Only way I can get any kind of connection after flashing radios for hours is to flash my restore, which brings me back to the edge2 network. I've tried the Good Blaze ICS newamss and the UVLG3modelfori717...n7005amss too, and while I do get a connection it's virtually the same as the existing crappy 0 to 1 bar, or none with a no-connection symbol.
Any help guys?
Anyone at all? I get weak to no.reception in most places and when I leave the city I have no.connection at all. If it was the radios then why wouldn't trying all those radios show improvement? At this rate I am considering just scrapping the whole thing and getting a phone tats locked to Fido if this is the best there is.
Is this the right forum for this?
Re: SGH-i717D Radio/Modem for Fido - help!
There is no such thing as a Fido radio. You flash a T-Mobile compatible radio (recognizes and uses the two bands/frequencies AWS), verify the baseband in phone settings is the radio you flashed, input the correct APN settings for Fido.
Things to check: your sim works with data in another phone, data is enabled in phone settings.

Thx... SIM works fine, data is enabled. Phone always says unknown under the baseband on phone settings. Pretty confident APN settings are fine, I had them confirmed with Fido. Is it just I haven't found the right modem/radio?
I tried the ones I've found most common in threads: iceblaze, KID, VK1 and even an UVDLE from an S2 thread.... still getting the same low, low signal, 0 to 2 bars with intermittent EDGE:2 signal.
Re: SGH-i717D Radio/Modem for Fido - help!
Ok, so you are sending/receiving data. But is that only using EDGE network or have you connected to 3G data network?
And if you don't have a baseband, the usual remedy is to return to stock at&t ICS rom and reflash your preferred modem.
Have you had better data strength with another device? Maybe two bars is all your location gets.

I know we are conversing privately but I'll continue the responses here in case it benefits someone else. I haven't been able to connect to a 3g data network yet.... Because my unit is an i717D (Telus), do I need to flash to the stock Telus ICS rom or do I need to use the AT&T rom?
I was using an HTC One S, same network but locked to Fido, default OS, same SIM card, and was getting perfect signal and data speeds. I can't see how a place like downtown Toronto would yield any signal issues... like you said it seems like it's a radio/modem issue.
Re: SGH-i717D Radio/Modem for Fido - help!
I hate to suggest it, but one old dependable T-Mobile compatible modem:
http://bayfiles.com/file/6FwV/WrxD5a/Blaze_4G_LB7_radio_ATTNOTE.zip
Its been modified and many have had success with it.
So I have flashed a stock Telus ICS ROM, and along with a stock Rogers radio am getting a baseband I717RUXLF4, Edge:2 signal, and even Fido under network. Getting 1-3 bars signal strength, but still no data.
I tried flashing like 5-7 ICS radios and all of them produced a 'no sim' on reboot. I had to re-flash the stock Telus ICS rom and the rogers radio to get it to read a SIM again...
Super frustrating as I feel like I'm going around in circles never solving the issue here...
Does anyone have experience with Fido modems in Toronto or Ontario? Everything I seen to find.is either for.Telus, Rogers, Wind or Bell...
Sent from my SGH-I717D using xda app-developers app
Another update for no one to read....
Tried flashing the Perfection ICS ROM... got same signal issues, installed the Rogers radio that seemed to work incrementally better with the stock Telus Rom... still floating around the issue of low signal...
There is a shockingly little amount of documentation on Fido setups here... most everything is either Bell, Rogers or Telus, with some Wind and Mobilicity.
Can ANYONE please provide me with some direction here? I think I've done my due diligence and respected the process for new people that these forums demand in terms of reading, research and such... I haven't spammed my issues anywhere else, and clearly seem to be stuck on this issue....
Ok, you need a modem that is 850/1900. at&t is 900/1900. So thats why you get 2G because in some areas you connect with a weak signal.
The Canadian stock rom and the Canadian stock modem for Rogers should work.
In network settings you may be able to select network frequencies. If so, select WCDMA only so your phone stays on 1900.
If that doesn't work, dial *#2263# and find the band selector, and select 850.
I recently bought the cell phone in US and am visiting India for a couple of months. When I tried using the GSM sims of both vodafone and airtel in in India I wasnt able to make any calls or rceiev any sms, despite of this being a WORLD PHONE.
I even rooted my device and by installing the APN MAnager I was able to install the Vodafone settings and to my surprise
Was able to get its 3g/Data services working.
However the Voice or the sms is still nit working.
The signalbar is showing just fine and so's the data connection symbol. However with the gsm sim in I keep gettin this NON VERIZON SIM ERROR icon on the top left.
Under the settings>MOBILE NETWORKS ive tried changIng them to both GLOBAL and GSM but still no luck yet.
Can anyone help me out with a network/sim unlock method, similar ti the ones avaialable on the tmibile and other phones.
Pretty sure the voice still uses CDMA. I believe that Verizon still only uses the LTE/GSM for data.

If thats true, then it wouldn't truly be a global phone now would it? GSM will work for voice, but you still need verizon's permission. It should work with a verizon sim, but you will pay through the nose. Now I thought the SIM was unlocked but I could be wrong. Also, even if it is unlocked, it still needs to be compatible with the network frequencies. I don't know what frequencies the VZW S4 has but you can google it.
This being a Dual Band mobile These are the bands that it supports..
CDMA 850
CDMA 1900
GSM 850
GSM 900
GSM 1800
GSM 1900
LTE 750
LTE 1700
WCDMA 850
WCDMA 1900
WCDMA 2100
Also on googling I came across some posts which said the people have managed to use there gsm sims in europe n korea and were able to get the voice n sms. For data they too had to play with th APN..
So what I am tryin to make out from this is we don have a solution to get the voice n sms working on gsm network

I used my phone and put in a Straight Talk (AT&T) SIM and it works with data and voice after manually putting in the APN. If Verizon phone works on AT&T network, it should work with any network out there provided that the bands are supported by the phone.
I was under the same impression, as it worked for me too when I used the tmobile(gsm) sim with it. I was able to make calls only and data was restricted.
Where as with Vodafone IND its the other way round. Am not able to make/recieve calls or sms but data 3g is working just fine.
Confused what could the problem possibly be.

If rooted, you can use Titanium backup, and freeze 'Setup wizard'.
What good would it do if I freeze the setup..how do you suggest I proceed further after freezing..?

I recall needing to call verizon and get an unlock code for my old droid 2 global so that I could use non-verizon global sim cards in it. I believe you just needed to be a customer in good standing for at least 10 months, and could only do it once a year per line, or something.
Edit: A quick search showed a post claming it is already SIM unlocked, so never mind!
Since only my Data is working on my VZW GS4, that too after rooting and installing titanium and apn Manager.
Just wanted to confirm if I am thinking in the right direction, Is it possible that I may flash the Stock Rom for I9500(international Version) in my vzw GS4, and it would work with any international carrier around the world, cos currently am only able to use the Data/3g and Neither Voice nor SMS is working out here for me for GSM carriers like Vodafone and Airtel.
Id really appreciate if anyone can help me lookup a workaround for this..
I just made to run my port of Android Revolution HD 2.0 for i545 (I was porting it from i9505). Everything is working, except CDMA-networking. It's multilingual as well. If anybody wants - I could give it to test. I asked mike1996 for permission to port it, so it is permitted

What is your phone carrier/provider, I would check what your provider supports in terms of Network Bands/ Frequencies.
You may likely need to switch to another phone carrier to have it working on 3G or better yet 4G.
If you do have the supported Bands/ Frequencies, I can help you with setting them to work with GSM network, LTE network, or setting between the two. (You just got to provide what country you use your phone if you are unable to provide your phone provider or simply do not know).
Hello, I have got a Le Max 2 with 6 GB / 128 GB (used, no warranty). Got it with ROM EUI 5.8.019S.
I have severe mobile network problems. I live in Dusseldorf, Germany, where LTE/4G (vodafone) never was a problem. The Le Max 2 shows 4G, often H or E or no service. Very rarely I get up to 15.000 kbit/s, but more often I get nothing. I tried with new APN, both SIM slots, vodafone and O2-SIM cards, reset to factory and finally i changed to Madsurfer ROM which works fine but does not change the network problem.
I don't know much about mobile network management but it seems like something is going wrong there. When my phone can not work with 4G it does not fallback to 3G or 2G but is completely offline.
Is it possible to flash a different modem?

There is description here how to check bands. Maybe you have US bands? There is also newest version of ROM 5.9 21s
If I help you please express it.
Do you mean the post about activating LTE / 3G bands? I tried this and it improved a little but only for a while (maybe random coincidence) and now it seems to be even worse. I flashed several roms with twrp but there was no improvement.
I found out that the modem settings are stored in special small partitions like modemst1 / -2 and you can erase them with fastboot. There exist some post about other phones where it helped to erase them and after a reboot they are created new (from other backup partitions) but I hesitate before I have further information - though I think I can not destroy more.

The modem files are changed by original roms.
Cooked roms do not change modem files.
so, try to install a original rom, like indian o chinese...
Try with the Indian ROM.
I flashed indian and chinese stock (with full wipe each time), did not help. Tried also madsurfer, TeamSpain Revolution and now Rom V6-X820 of Bshuy2003.
I still get network, internet works, after a while I can't download anything and often lose network completely or get E(DGE) though LTE signal should be good even inside building (in Düsseldorf) where I am testing. My Note 4 gets 4G all the time with no problem. I do not only have that problem in buildings though. Net is unreliable even outside. Works and then stops working after a while.
I installed LTE Discovery and found out: The Phone connects to LTE band 20 station, RSRP from -70 to -90 dBm (which is good), I can download at reasonable speeds (not very good though), after a while it connects to LTE band 3 or 7 stations with bad RSRP (above -100 dBm, often -115 dBm) and I can't download anything (My Note 4 can even with about same RSRP). Often it then moves to (E)DGE. If I restrict the Phone to 3G sometimes I get H or H+ (HSPA) but no good connection. Often carrier is lost completely. Sometimes LTE Discovery app states "Potential eCSFB issue detected", maybe there is a problem with the Fallback management.
It would work if the Phone did not change vom LTE band 20 to 3 or 7 stations.
I found this in CatLog, could it be related to the problem?

I didn't face such issue. Probably hardware problem?

Flash it with twrp and reboot.
I have a 4GB X820 and use USA AT&T. After recovering my phone from a hard brick using FlashOne, my cell data (voice would still work) would never come back up after switching out of airplane mode, and I'd have to reboot to get it to work again. Also at times, I would be in my house and would watch my signal go from full bars to one or none, every several seconds. I just flashed the 16s v.00024 modem in the USA folder from the link sky104hk posted and all is well so far.
For reference, my old modem was MPSS.TH.2.0.c1-00229-M8996FAAAANAZM-1 1
Thanks for the list of modems!
My phone no longer connects to the Tmobile network. It will connect to some towers and not others. Did tmobile push some sort of update? Many places I just get no service. I tried flashing the 26s radio, but still no dice. Or is the cell modem in my phone broke?

Hello and thank you for your work. I have an X829 and I want to use it with European frequencies including the B20. What version of modem should I flash. Because I don't read Russian. Thanks
None of them. X829 does not support B20 so you will get LTE only in areas with B3 coverage. X820 supports both of them.

Dear siijii, I have the same problem.have you find a solution? Thanks
Hi,
Thanks for sharing Modem files.
I just got X820 but for some reason it is not connecting to LTE Band 20.
The ROM it came with is 5.8.019S
The questions are:
1) Is there any hardware difference between International version and Chinese version?
2) can i flash Chinese ROM on my x820 (my mobile has CE0560 written on back cover, so i assume it is international version)
3) When selecting *#*#4636*#*# >> select radio band >> "set GSM/UMTS band" list is empty, so do you think i need to flash modem to get European band profile here?
4) Which modem file should i flash for band 20, the Modem directory i downloaded from your link, has Russian language directory name.s If i use Google translate i can see the directory name with modem files are "For developers" , India, China, Russia & USA. No modem file for Europe which has Band 20 enabled?
Thanks in advance.
Take a look at the backside of your X2. If there is a branding in the downside of it, it isnt a X820. Got the same problem, bought a X820 and became a X829. Luckily, I got B3 here working.
