Hey guys, recently I've got an Alpha SM-G850A which is for AT&T. I live in Iran and the phone has been unlocked to work here, I was trying to get the Android Lollipop 5.0.2 for my phone. so first I tried to get the update from AT&T software update by phone, but it says that there seems to be no updates available for me, nevertheless on the net the guys claim that they've got the update, is it due to my location in Iran and my internet IP? (I used VPN too but again, no updates). I tried to get the firmware from Sammobile.com too, but there were no firmwares detected for SM-G850A. Can someone help please?:good::good:
BTW, I've got the cellular data from my operator, and it works, but I can't select which type I wanna use (2G, 3G or 4G). I mean there's no options in the phone settings to select the data connection type. NEED HELP!

Even tho the phone is working on other networks you will still need an at&t sim card to update it. There is no way around this as far as i know.
Type below code in dialer and select Device information. Now, if you scroll down you will have the option to change network type.
Code:
*#*#4636#*#*

I m from pune and,Recently I activated airtel 3g in my samsung galaxy ace... Bt problem is that I m not getting 3g signal.
In samsung galaxy 3 there are options like dual mode/3g mode,bt in galaxy ace when I go in mobile networks there are this options : enable packet data, data roaming, access point name, mobile operator, use only 2g networks.according to airtel customer care I should chk on enable packet data and unchk on use only 2g network options I did so bt still can't get 3g,signals..
I tried to use 3g signals in many places in pune..bt still I m jst,getting edge connection
Are you sure there is 3G network? If so, did you make sure that in APN list there is the one provided by your carrier for 3G ?

Have you checked your APN settings?
Uncheck 2g mode only. If still you not see 3g symbol at left side of signal then in network setting go network operators and search available networks and choose airtel 3g.if still not get then go into keypad and type *#*#4636#*#* and select option phone imformation and in that you see gsm auto selected. In that choose wcdma only and press turn off radio then press turn on radio now press home button(not back button). You will get 3g. If not then reboot. I hope this will help you
You are using the wrong ROM or MODEM file with a Band Operator that's not supported for your company. Review the frecuency of your operator for 3G. Then, flash your phone with the correct ROM.
Hello everybody!
I installed the rom version 2.3.4 (vivo - Brazil) in my galaxy s5830L (3g 850/1900MHz). My mobile carrier works with 3G 2100MHz, so I can not connect to 3G only 2G (edge).
Do you know if there is any possibility to enable 2100MHz in s5830L 3G?
Thank you!

Hey I tried ur method of dialing that code and then changing it to WCDMA mode ..after selecting this option for some time in status it shows no connection like a white circle with cross line in it and after few seconds it again shows Edge connection ..and again u enter that code in that network type option it again automatically gets change to gsm auto!!
Now I m really getting frustrated by this problem I called Samsung helpline they said for using 3g in some mobiles u have to do a Software Update in Samsung Service centre after which u will get that 3g/dual network mode option in ur Mobile network settings like other mobiles, bt I doubt if they can really help me bcozz about 2 months ago I had already done a Firmware update earlier its version was KC1 and after update its version is KC7 which i think is the latest version of Firmware available in India for Samsung galaxy ace. I said this to Samsung technical Support but they say that Software update and Firmware Update are completely Differnet things…
So I want to know whether this Software update and Firmware update are this realy different Or its same. I have also Noticed one more thing in “Samsung galaxy Fit “also there is no Option like 3g/dual Network mode to Enable 3g!! is that option diabled in all galaxy Ace & Fit models or is it only in my cell???

After selecting wcdma only turnoff radio and again turn on radio then push middal button called home button. When you doesnt want 3g mode tick on 2g mode only.
I also suffer from same problem when i use bsnl3g. You should camplain in airtel servise center because it is not fault of mobile but fault of network provider. If you want to chek then insert other sim and uncheck on 2g only and select access poit . If you get 3g then your mobile is not in fault. I want to know that you get 2g internet on that airtel card? And you choose access point?if not then select access point

dude i think u are not reading my posts completely..i can say this bcozz right from my first post of this thread i m mentioning that with same sim card of airtel i m getting edge connection..and the problem is not with sim card its with cell itself bcozz when i tried same sim card in other mobile i immediately got 3g signal in same area..that bcozz after lots of search on google i saw that many are facing this problem of 3g not connecting..its due to a software bug in froyo 2.2.1 so people say only way to solve this problem is we will have to upgrade our froyo to 2.3.3 or 2.3.4 this might solve our problems bt still i have some queries which i have to clear like see if u can ans them :
1. which one will be better to go with android 2.3.3 Gingerbread or 2.3.4 Gingerbread for Samsung galaxy ace I mean which one has less problems and will solve my 3g problem!!
2. after unofficially upgrading to 2.3.3 or 2.3.4 will I be able to officially upgrade to 2.3.5 through kies in future.
3. For upgrading to 2.3.3 or 2.3.4 is it necessary to root the phone..
4. how much time does a whole upgrade process takes if my internet speed is Minimum 1Mbps…
5. How to come back to 2.2.1 Froyo Default version from 2.3.3 or 2.3.4(Steps with video or Img link will be very helpful)
Update to 2.3.4 is realy easy and not require root. You should first download 2.3.4 flash file and after download use odin to install flash file. When official update comes you can downgrade your phone to froyo so kies update it to latest version so chill.
My email is [email protected]
contact me i will explain you how to update to 2.3.4 and where to download

I hope you undarstand because you need to flash two firmware to get ddkc1(indian firmware)firmware back. So wait for that. But i ensure you that you will not downgrade in near future because gingerbread rocks

Hi.
I bought ace S5830 from USA (and this phone only support 850/1900 Mhz), but i live in Azerbaijan and here I use mobile operator sim that only have 2100 mhz band for 3G network. Logically, my phone can not connect to 3G network. My question,
1.is it possible change the band?
2. If it is possible, how we can change, upgrade to new firmware ?
p.s. I have upgraded it to GINGERBREAD.UBKP7
Please help me to solve these issue,
Thank you before hand.
plese help me with problem above
Hi,
I am on t-mobile network, my problem is that i don't seem to get EE network on my S3, it will change the between t-mobile n orange not ee. When I insert sim into iPhone then I will get EE network. I have tried unrooted n rooted but no EE.
Now when am on t-mobile network my Internet is really good but as soon it's moves to orange network then Internet is really really slow, I mean 34kbps.
I have contacted t-mobile n tried everything but no luck.
Is this something to do with S3?? Anything I can do? Any advice appreciated
ta
I'm on t mobile/Orange through t mobile, Orange signal is rubbish, never gets h or h+, but as I'm on t mob, it reverts to them by preference I think, only switching to Orange when it looses signal.
I used to be on Orange, and then I always had to go into settings and select network (choice of EE or EE!) So it's a bit hit and miss.
I also sometimes get it showing as t mob in notification draw, and sometimes EE, all very confusing.
EE sucks!!! Nothing wrong with your phone.... I've got Orange and 3UK. With the second one I'm more than happy. Download up to 26Mbps!
I never get EE on my S3....do you ever get EE?
Also is there an easier way to swap networks?

Are y you with orange or t mobile?
I'm with Orange and I've never had a problem in having H+ my carrier signal mostly shows EE.But isn't that all it is? a re branded carrier signal from orange and T-Mobile?
It's weird cos I get EE network when I put sim into iPhone
T mobile
Why is it that I don't get EE anywhere? Also I do get H+ but Internet is awful... Am thinking it's something to do with my S3 or firmware, radio etc

Are you on latest mb5? Are you locked and branded?
Also don't about it displaying ee or not, the other thing you could try is go to tmob website and get the apn settings sent to your phone, they may need updating
Sorry don't know about mb5? How do I find out? Plz
Unlocked n unbranded
I have done t-mobile website but apn setting does NOT come over to my phone for some strange reason... I have entered ee apn setting manually but still no EE network. I am not fussed what network it is on as long as I can get Internet!
Currently limited Internet on orange n full on t-mobile.
Download mb5 here. http://live.samsung-updates.com/details/7693/Galaxy_S_3_International/GT-I9300/BTU/I9300XXEMB5.html
Flash with Odin, this is the latest UK unbranded
Once you've flashed the MB5 modem & matching RIL, go to settings, more settings, mobile networks, network operators and make sure 'select automatically' is chosen.
Then go back to mobile networks, access point names and delete all the APNs listed. Then create a new APN but only complete these fields; name: Everywhere APN: Everywhere
Reboot the phone and you should have a better experience.
You can also find a CWM flashable MB5 modem & RIL in kamalmawa's thread:
http://forum.xda-developers.com/showthread.php?t=2076857
I already have that installed..xx mb5
Am also rooted on vanilla rootbox... Is that a problem?

Have you contacted to your operator it could be helpfull also
Yes.... As far as they concerned everything is fine.
Also bear in mind that the network is undergoing a lot of engineering at the moment due to the marrying of the two networks and the LTE network introduction, but for me Orange has always been rubbish so I just select t mob and live with the pain of selecting the network occasionally if it gets hung on Orange

Just flash the zip in recovery, the RIL is included and it will even backup your existing modem. No need to play with root or the ROM, as long as your current ROM is rooted.

Hi everybody!
I'm using a SGS III SHV-E210S (Korean LTE) running the official 4.4.4 KitKat ROM. I have been able to connect to the 2G network in my country in Africa since I got this phone. However, all the mobile networks here changed to 3G a few weeks ago, and since I have been unable to connect to the data network.
The only way I have been able to have my data connection working is by changing the network mode in the Hidden Menu from default "LTE 850 Preferred" to "GSM ALL", but this only gives me access to the slower 2G connection. All other options show 3G but the phone has no Internet connection.
I thought maybe be it could be a baseband incompatibility issue in the stock 4.4.4 firmware? So I tried flashing the modem for 4.3 on to my phone but no success with that either. Is there any fix available for this problem?? Any links where I can get it as well will be highly appreciated.
Thanks in advance.
Peace
Hello Guys,
I have a Tmobile s6 edge. I have unlocked it to use in Brazil. Everything was working fine but I had a trouble with root and ended up soft bricking (not passing the Tmobile logo screen)
I managed to reinstall Tmobile stock rom and make it work again. All was fine but this afternoon the phone decided not to register on the network anymore. Weird thing is that I still have connectivity over 4g. I tried a Tmobile Sim card and get the same problem.
Any suggestions? Should I root it and flash a custom rom? Different radio? Everything else is working fine.
Thanks!
Turned out that the imei was blocked. I managed to change it through a company in the US. Now it's back to normal.
Go to settings > mobile networks > network operators and select search automatically.
If this doesn't helps then tap on search networks and select manually,this worked for me.

Hi guys , i dunno if this is the right section for this question but i'm a newbie here , i got two sm-g925r7 locked to nTelos i think and i want to unlock them for international gsm use outside the u.s , is this possible ? if yes do you know a guy who can do them at a reasonably price ? since this can work on sprint cdma phones i don't see why it can't work on nTelos since they are both cdma ? correct me if i'm wrong , i need your help guuuuuys please.
How do you know if they're locked to nTelos? Did you try putting in another carrier's Sim card? Uru
nothing happens
i know couse i bought them on ebay and the sellers stated that in their description , and the sm-g925r7 is for cspire or ntelos only ? i tried using a foreign sim card , ( i'm outside the u.s ) and nothing happens , phones search for network 2-3 secs and then they just show that little barred signal icon on the top right corner
Well on the nTelos website it says all android phones are unlocked so I dont know.

I hope flashing to sprint version or trying with different bootloader / modems could be the solution, I have not found any guide yet
Ok so i rooted the phone and used root explorer to enable service mode , restarted the phone , opened service mode and selected lte/gsm only , restart , phone asks for sim pin and then nothing , no data sms or calls
I am also interested in this unlock but haven't found a solution yet.

after enabling lte/gsm only, restart and go to settings > network mode > select lte/wcdma/gsm. try with different carriers and 4G sim cards to get signal (mine is working on Claro only, other carriers show "Searching" or "No service" )
If this is the go25r7wwu3cpc1 how did you root?? I'm on firmware 6.0.1 can't find root anywhere..

you tryed to unlock with z3x box?
g925r7 is currently not listed in Z3X box support list.
need rmt_storage patch to make changes to bands inside the phone.
inside item 1787 (3G GSM bands), this item has no support.
Reason why it doesn't work for calls is because VOLTE is not enabled by default in CSC
usually a device like this will fall back to 3G when making calls on GSM networks. Thus the reason why calls aren't working.
