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!

How to review frequency of operator for 3g..
And one more thing when I tried with same sim card in same area on samsung monte I immediately got 3g signal jst after selecting 3g mode..so I want to know do u still think there is a problem with rom....
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

K gr8 ..jst 2 questions how to downgrade back to froyo 2.2.1 I mean steps... And secondly does 2.3.4 gives any problem I mean any hangs, etc...
2.3.4 not hang atall. It remove lags from many games. I use it from 2 months and not get any problem. So just update. And abowt downgrade i post in my blog tomorrow. 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
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 :

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 friends,
i was playing around with the title code of this topic.
After entering *#*#4636#*#* in my x10,i selected phone information,pressed the physical menu key on left of phone,than clicked "select radio band". In that there was only option under the "set gsm/umts band" which read "usa band".
I selected that and instantly lost network signal. I live in india and the phone is of usa at&t unlocked.
Now i am not getting signal. I tried to press the menu key again but it reads "usa band only". Tried to manully select network,but no luck.
Finally i also did factory reset,wiped cache partition,reflashed my wolfbreak rom ,but could nt get signal.
What else can i try?
is there any one who can help?
IS there anyway to rollback to original/default settings/bands?
any chance that there is a restore, or similar button inside that menu? Have you checked this?

Okay, here's the fix - I found this out because I did EXACTLY THE SAME (curiosity killed this particular cat!!) and PRESD BUTAN (USA Band) without thinking, on my Japanese X10 (SO-01B), which, as you did, set my phone to the wrong band for Japan. Duh!
Anyway on to the fix...
1) Bring up the service menu with *#*#4636#*#* at the phone dialer
2) Select Phone Information menu
3) Switch the phone to FLIGHT/AIRPLANE MODE (I did this by dragging down the top menu bar on my phone which is running a custom rom)
4) Press the menu key and SELECT RADIO BAND - you'll see the complete list of country bands - do NOT select a band yet....
5) Switch FLIGHT/AIRPLANE MODE OFF
6) Select the country Band you require - you should now see a success message.
7) Congratulations on getting your cellphone signal back
Regards!

I'm on lenovo zuk z1, and having the same problem. I would like to try this solution out if it does not mess with the communication functions.

did you try to change the modem? or you can check this with other rom whether it is working there or not.

you could try checking your apn settings, detection of apn are different on different roms.
or try forcing the network to use WCDMA mode (go to phone, then dial *#*#4636#*#*), go inside the first menu there and force it to use WCDMA (incase the rom toggles are misbehaving)

no apns are right as i can connect to edge network just fine in evry rom.
So by a stupid mistake I have selected in *#*#4636#*#* the Radio Band to USA. The signal suddenly dropped and it stopped working at all, the nework does not connect except in 4G and only for data. Calls and text are not working, only 4G data works fine. This is on the sim1 though. On sim2 all is ok (except that with the X829 ROM, on sim2 I have no data, and on sim1 I have no calls )) ). I was on sim1 when I've changed the Radio Band, so I guess that only this one got affected since sim2 is working properly.
Is there any Radio Band files that I can restore? Or some app that can restore the settings of the modem?
Any help is highly appreciated.
PS: Reinstalling the ROM (clean or dirty) doesn't help. Factory resetting also doesn't help. I would downgrade to 014s but I'm afraid not to end up with a brick.
Change the rom

If i were you. I would change the rom from china to indian rom. It would help you. The radio band of chinese rom and the indian rom is different. It would replace the radio band of chinese rom and if it doesn't work. Then return to the chinese rom
I'm 100% sure it would help you.

I did the same thing by my mistake.And my le max 2 also became not able to connect internet. In my case, it can't connect both 4G and 3G .
But I fixed it. But I don't know that it get back to the original completely.
I'm japanese.And I'm sorry for that my English skil is very poor.
My current rom is Le2_X820-MAX_ROW-5.8.015S_V29_CUOCO92.
I used DFS CDMA TOOL and checked the items on the "Band Preferred" same as "RF BC Config".
1. download HTC Diag Driver. You have to customize .inf file later.
2. conect device to your windows pc and choose MTP and USB Debugging.
3. enter the follows command.
"adb shell"
"su"
"setprop sys.usb.config diag,adb"
When you enter this command, your device change over diag mode.
4. diag driver install.
You have to find hardwawer ID from device manager.
And replace the hardware ID in .inf file.
5. If you install diag driver correctly, you will be able to use DFS CDMA TOOL.
sorry, I can't explain any more..English is difficult...
I bought my phone from china and I'm in US, and it works perfect on stock with LTE enabled for AT&T by default. Might I ask why did you change it to US band and it stopped working? It would still work right?

Many thanks for the advice but it didn't help. I had installed the indian rom and then to the chinese without any change in the behavior of the modem. I'll try the chatmonchy's advice to see if there will be any improvement.

Actually I'm in Europe and looks like we use slightly different bands (??). I get 4G data but without calls. To other networks like 2G and 3G it connects sometimes but it's for few seconds only. I even don't remember what made me change the bands to USA, I guess I was curios what settings those were. The options are "USA band" and "Band 6", neither one is working well for my device. And strangely though, there is no other option to go back like "Auto" or something. It seems that I'm not the only one that did it. After a google search, it turned out that a lot of people had the same issue. For some, the factory reset helped, for others was flashing via TWRP the radio bands again.
I had solved the issue and I will post a guide later on for those who want to unlock additional bands or did the same mistake as I did.

thread: [SOLVED] Accidentally changed the Radio Band to USA
Hi, gyus
I had the same problem, i select USA band and everything went wrong,
The simplest way for me was:
installing "X820 LeMax2 RevolutioN_Team Resurrection Remix", no other from TeamSpain, only Resurrection Remix
http://revolutionlemax2.blogspot.al/
https://mega.nz/#!T9o0wAhJ!iLa9mrPAr...VkCg3_L-q2RgnA
then after installation, go in dialer and call *#*#4636#*#*.
There are three band: Automaic, USA, and EURO.
I select the EURO and everything i'ts OK.
BEFORE DO ACTIONS DON'T FORGET TO BACKUP ALL THE ROM WHERE YOU ARE WITH TWRP

Does not help. If I go to servise menu (dial *#*#4636#*#*) , I see Radio turned OFF and I can´t change it. How to solve this ?
Did you post any guide how you solved the issue?
Unfortunately USA band selected
Hi,
I live in India. I bought Oppo F3 Plus (CPH1613) 4Gb Ram, 64GB Storage, Qualcomm MSM8976 Pro Snapdragon 653 a year ago and was working too much fine. I was wondering about Qualcomm mobile secret codes and found this *#*#4636#*#* . I dialed this and accidentally changed radio band to USA band and suddnly on instant my mobile didn't get any network signal. From then, I went for Oppo care, and mobile repairing shops and self tried and tested for lots of time; but everyone unable to bring phone to normal. I reset my mobile, flashed stock rom for countless times, wiped all data but nothing helped me out. Finally i rooted my oppo f3 plus and tried to boot in fastboot mode; but Oppo removed bootloader and fastboot mode from 2016 (as posted in XDA). I got a little link about resetting USA band to automate and is erasing modemst1 and modemst2. But again it have to be performed from fastboot.
Help me out for my mobile.
You can flash a modem file, it will reset it as well. Changing the ROM won't update the modem configuration. Try to search modem files and flash them via TWRP.
I screwed up band modes, in Engineering Mode i unchecked band modes for LTE except Band 3 and clicked set and then rebooted phone, now phone does not connects to sim at all and no band is checked at band modes in engineering mode as well. opening it says "Query Current Mode Failed", "Query Supported Mode Failed".
really need help to fix it.
flashed rom but still doesn't work
IMEI numbers gone, how to fix that?
Also, on About Phone > Baseband version is showing "Unknown"
IMEI restore than sim will working
I was have same problem. I restore NavRam or NavDATA from backup was i created from TWRP also u can restorefrom MetaMaui 9.1 Application from pc.
