Problem about 3G on my rogers captivate

I am using the rogers captivate and i just flash my phone to the I897UCJI6-OCD-REV02-Low-designgears(1). However, the phone works a little bit slower than before and I cant use my 3G function from rogers. Is there any way I can go back to the rom I had before? Or any way to find the 3g function back?
Thanks
You did enter the apn settings right? And you should of saved your rom before you flashed the new rom, otherwise flash with this http://forum.xda-developers.com/showthread.php?t=731989
3G WORKS
I forgot to set up APN......Now it works. thx for the help.

PLEASE HELP! 2.3.4 and suddenly can't connect to my network (Bell Mobility)

Hello,
Please help if you can! I updated my Nexus S to 2.3.4 the other day, and everything was working fine. Today, the phone at some point lost the ability to connect to my network (Bell Mobility). I was out and about and was turning data off, and might have hit the 2g/3g toggle by accident, and seem to remember reading about that causing problems - though I have no idea if I did for sure (the sun was bright) and am honestly not sure what's wrong EDIT: when I go into wireless & networks\mobile networks\network operators, the phone will only recognize Roger's Wireless (and it was bought at a Telus store!) The UI still works fine, and I can still connect via wifi - just no way to get it to recognize Bell's network
As stated above, everything was working fine this morning - voice, data and sms all good. Here is all the info from my phone:
Android version 2.3.4
Baseband version NO DGSXXKD1
Kernel Version 2.6.35.7-ge383d80 [email protected] #1
Build number GRJ22
The bootloader is unlocked, and I had been running CM7 before flashing the manual 2.3.4. I'm not sure what to do. Tried re-flashing the manual 2.3.4 update.zip, and nothing. I know a very little bit about rooting/flashing (just enough to follow guides), and am wondering whether I need to re-flash a different kernel/radio/rom or something. I did search, and couldn't find anything that outlined my problem exactly (I do apologize if something is out there and I just didn't look hard enough).
Again, the phone was bought new at a Telus store, and found the Bell Mobility network out of the box no problem. Am hoping someone can help!
Thanks so much for reading, and if you are able to help.
Check your APN's to make sure the data info is in there I had to manually enter mine (bought phone from Telus to use on Bell/Sasktel's network) for Sasktel and bob was my uncle
Every upgrade i need to put them back in. No automatic for me, so i would start there
Menu - Settings - Wireless & Network - Mobile Networks - Access Point Names.
If nothing is in there, you need your APN settings. Talk to bell support for the info, and they should be able to help you over the phone (they support android even if they dont sell a Nexus S)
Cheers!
Thanks so much for your response, though I don't think that the APN's are the issue at all; they're still in there and fine. I think that it's the actual radio (or baseband), as the phone will not recognize the bell network, only the Rogers network (and it was bought new at a Telus store!)
I think that I need to re-flash the radio, and maybe the kernel. I searched to try and find the radio image for my phone, but haven't found anything clear enough for me to be comfortable to try - I've read time and again that flashing radios is one of the riskier things to do. I don't think that my phone is bricked (can still boot it up, and all of the ui works and can connect via wifi). Don't want to risk doing more damage.
Thanks again for your response though!
i think i'm having the same problem. i've manually upgraded to 2.3.3 then to 2.3.4. and then i put a sim card in - not used it as a phone before this.
i can get 3-4 white bars lit up but can't connect to any network. the bars turn green when wifi is active, but still can't connect ("can't connect at this time. please try again later" toast appears). not sure if the phone is borked, or if the upgrade wasn't that successful.
I actually have this same issue but using it on at&t in the USA...Really hope it isn't broken cause I have no way to fix it since i'm not in canada
Maybe check if the 2g box is checked in mobile networks. Check your apn settings and if that doesn't help try and flash another radio.

i'm unrooted, and don't intend to root. apn is fine as suggested above, and regardless of 2g checked or unchecked, still no connect
Rogers is the only 2G gsm provider, your phone may be stuck on 2G. If you have the choice, I would go back to 2.3.3 full stock and see if everything then works.

No. you are best to use cwm and restore a stock image for your phone
Sent from my Nexus S
Your best option is to flash back to 2.3.3. Download rom manager from the market and flash clockwork recovery. Once in recovery flash the 2.3.3 .zip file. I saw it somewhere here but i forgot where I saw it. Hope that helps.

Try this http://devsforandroid.com/index.php?board=18.0
I'm NOT SURE if it'll work, but it's worth the try. Make sure to to wipe everything before you flash. I'm not responsible for any damage this may cause. But I hope this helps you out.
If anyone wants to chime in and correct me please do so.

Or if you're not comfortable flashing the stock 2.3.3 rom maybe just try and flash back the xxkb2 radio which I believe was the stock baseband for Rogers, telus, Fido and bell. I have the .zip file for you to try and flash through CWM if you need it. Otherwise you can find it somewhere here aswell.

i'm not looking to root nor use any 'hacks'. i don't trust them.
under the battery, the phone is just a i9020. no letter afterwards.
Flashing a ROM doesn't require root, it requires unlocking the bootloader, which Google officially allows you to do that. You can unlock the bootloader, flash 2.3.3 ROM, then lock it as if it had never been unlocked. Just keep in mind that unlocking resets to factory default and wipes your SD card clean, backup before you do it.
Ahhh yes, I had same thing except with Telus I fixed it once, but the second time I could not get it to work, do this, flash this radio
http://forum.xda-developers.com/showthread.php?t=1044261
it is the stock radio your phone came with, then call up bell and get them to "repush" your sim card... hopefully you will see your network again.

It depends on which ROM you flash. I flashed the official 2.3.3 ROM, it contains the radio image, it'll flash it as you apply the update.
Do you remember which baseband version it came with out of box? That should give us hint as to which radio applies to your phone. I think there are really only two types of radios used except NS 4G, 850/1900/2100 (i9020A radio) and 900/1700/2100 (i9020T radio). You can ask your service provider or check out their website which band you are running on.
Back to flashing ROM, I just realised you don't even need to unlock the bootloader if you are flashing Google signed files. You should most likely be able to flash a 2.3.3 full ROM, then flash the 2.3.4 update file. But if you find the 2.3.4 full ROM, that's even more convenient. I saw a full ROM on the forum, but I that was for i9023 or i9020. Not too sure, maybe others know.
For the Canadian carriers, as stated before, Rogers is the only 2g (edge) carrier all others (Bell, Telus, Sasktel) are 3g (HSPA). go Settings>Wireless & network settings>mobile networks and ensure "Use only 2g networks" is not selected.
If this does not work flash the KB2 modem, the other modems may lose 850mHz spectrum which could be causing your grief.
Solution!!! (At least this worked for me!) - Didn't have to flash anything
Hey all,
I apologize for not posting this sooner, but found a solution that worked for me, hope it might work for others experiencing the same problem.
**PLEASE keep in mind that though this worked for me, I don't know if it will work for you (maybe it might make things worse for some people). Especially keeping in mind that I DON'T KNOW FOR CERTAIN what originally caused the issue for me, nor what specific factors (rom build, phone model, radio image, etc) might have contributed. As well, I am on the Bell Network. USE ANY OF WHAT'S STATED BELOW AT YOUR OWN RISK. Disclaimer stated, read on...**
In the dialer, I punched in *#*#4636#*#* and then from the menu that popped up, selected Phone Information.
From there, in the Set preferred network type: drop down menu (scroll down a little, you'll see it) I selected GSM/CDMA auto (PRL). **Again, remember that I'm on the Bell Network in Canada. Should you be trying this, these settings might not be for you. Again, AT YOUR OWN RISK**
Then, still from the Phone Information screen, I pressed menu button (the hard menu button on the phone), and then chose the Select Radio Band option. From there, I believe I selected Auto, though I may have selected USA (It's been a couple of days, and I can't remember, I apologize).
After that, went back to the Phone Information menu, and pressed Run Ping Test. It seemed to show all of the necessary (and appropriate for my network) settings as ok, and... everything worked!!! Full network connection as before!
Hope this might help someone else! Keep in mind that I'm not sure what caused the original problem; I do believe I remember pressing the 2g/3g toggle, and also remember reading somewhere that this can cause problems. Specifically, that it stopped peoples phones from going back from 2g to 3g - in my case (Bell Mobility) there is no 2g network to drop down to, so if it got stuck on EDGE mode, it probable looked for the only local carrier with a GM EDGE network, (Rogers) and got stuck there. Not sure, but maybe this is what happened. Any wise folks out there that might be able to confirm/offer insight?
Anyhow, thanks so much for all the responses and offers of help!

[Q] Broken Recovery, No Signal, No Ability to Save APN

Hey everyone,
I used to have a Sidekick 4G that was rooted and ROM'd so Im not neccessarily a noob to this, but still a bit. I bought an LG Optimus T (T-Mobile) as a replacement for my broken Sidekick. I'd had the phone before so I knew it was a decent phone, and for $40 on eBay, a deal I couldn't pass up.
Here's the story: I rooted my phone and got a ROM loaded on New Years Day. ROM was fine, but I decided I wanted to change to a newer version of CyanogenMod this past Saturday(1/5). So after testing out a few ROM's, I came across one that unfortunately didn't flash properly. When I tried to go to use the phone, the main Android OS crashed. I had a black screen with the nav bar displaying no SIM card(which was accurate), the time, battery life, and no signal. Once my boyfriend got home and was able to get the phone to finally boot into CWM and flash into the new ROM, even with my SIM card in, I had no signal. I thought maybe it was an issue with the APN so I went in to try to fix it and none were listed. When trying to add one it, it never saved.
My recovery in CWM goes back to the broken ROM, unfortunately. When trying to unroot, Superuser begins to not respond when its trying to uninstall either busybox or Superuser. The phone works fine, I can connect to WiFi and use it and everything.
My question for you today is does anyone have a recovery of the stock ROM that they can post that I can flash into, or any tips on how to fix this? I thought maybe my SIM card is fried for Android, so I thought of calling into T-Mobile to have them activate a spare I have laying around, but would that fix the issue?
I really appreciate any help that you guys can provide. Thanks in advance!

Phone has no radio/baseband, help please

Somehow I ****ed up and now my phone cannot receive cellular signal at all. In about phone, IEMI number is unknown and in SIM card info, everything is unknown. What I did was this.
1. Flash CSC Selector on my existing ROM selecting ATT CSC. Everything was fine (aside from no voice/wi-fi calling)
2. Wanted to update to latest stock PDA/radio/bootloader so I did (through Odin.) Everything still good.
THIS IS WHERE **** HIT THE FAN
3. Flashed TWRP.
4. Formated data, flashed CSC selector selecting ATT, flashed Makisk, flash Makisk-PHH rot.
After that, no cellular signal at all.
Can someone help please? I really need this phone for work and if I can't get it working tonight, I'm going to have to go to AT&T store and ask for the cheapest phone they got until I can get this fixed...
BTW I already tried re-flashing everything to stock through Odin and it did not help.

T-mobile 4g internet works but I have calling problems

I have the international Note 5, with a t-mobile sim card. When I am on the 4g network and I try to call somebody it takes 20-30 seconds to call. When people call me, they can't reach me. Though the 4g internet works like a charm.
The only way for calling to work is to switch it to 2g, but I am loosing the 4g internet speeds.
I contacted t-mobile, they tried to reset the network, but the problem persists.
Any suggestions?
Would flashing with a custom rom help?
Should I flash the original t-mobile rom?
unce unce unce
I found the problem
The problem has to do with the volte... This option is not available with the n905c model that I have, and there seems not to be a fix with t-mobile. Fricken Samsung didn't put available this feature in the upgrades of some international phones eg the Dubai model that I have...
I have the same problem
I just bought two t-mobile branded Note 5's and I'm using them on Family Mobile (previously owned by tmobile). If I limit my networks to 2G & 3G all of my calling works fine but the moment I enable LTE all of my incoming calls go strait to vm. The problem persists on both phones so I don't think it's a hardware issue. I've tried rooted and unrooted, magisk and supersu. VoLTE is turned off on both phones (since it's not supported by family mobile) but I've tried every combination of settings I can think of and nothing helps. I hate having to choose between having LTE or getting incoming calls and would love to fix the problem. Or is there a good way to totally disable or remove the VoLTE services? If I remember correctly there were similar problems with some of the S4s that required an app like advanced signal status (??? been a while) to overcome. Can anyone help? Please and thank you.
I have the same problem
Hi all,
I have the same problem, even I have install & root with custom rom the problem still exist.
someone told me that the problem is in 3G signal.
so I decide to choose LTE & GSM only, & it works for me. however it could not give 3G signal on my phone.
Did you find the other olution of this?
Evening all, I've been having this same issue, hoping there would be a fix. Not ready to purchase a new phone when there is nothing wrong with the one I have still good for at least another yr(maybe). but not rite now.
i fix the problem
Hi all,
maybe this method could solve the issue. please try it & follow below step.
1. reset to factory setting then after finish please clear Dalvik Cache.
2. Flash with the latest Odin & latest firmware, but you don't need to change everything in options tab. then click start.
3. After finish, then insert APN as mention in this link (please read how to set APN on Galaxy note5)
4. After select your desired APN, please change APN name become ****4g.com (or you can find this apn setting in your carrier SIM (check in google)
5. Finish, please check your phone.
hope above method could solve the issue, however it works for me now.
please try at your own risk & don't forget to always save your data before.
This is the FIX for the Note 5 SM-N920 C, i know this works because i have been dealing with this for MONTHS, so i tried EVERY Custom Roms Untill i figuard WHY NOT flash a Stockish T-Mobile Rom with a Custom Kernel for the 920C. And Just like that i got My Awesome Note 5 BIZACKKK, Here we go, Follow these steps, Upgrade to the FIRST 7.0 that came out for the SM-N920C, of course you should already know to turn on debuging + OEM, Flash TWRP through Odin, then go to the TMOBILE Development Section and THANK "@Marinella" First and foremost for cooking up this Rom, Download his Stockish Unrooted Rom ++7.0 ROM Stock Unrooted N920TUVU4EQE1++you will also need (MAKE SURE TO THANK--->>> ""@AndroidSword"" ) this 7.0 Kernel, go to the seack bar and type it in, FUEL-KERNEL-V2 .... now before anything, Of course do FULL WIPES Of Everything like you usually wipe when downloading other Roms, flash the stockish Rom first, then the Kernel, Just so you know, the Kernel has 2 choices of root. ITS AS SIMPLE AS THAT>>!!!!, Boot your Device and wait, this took me months to figure out after flashing so many diffrent Rom, Now I Have My Favorite International Note 5 Back, trust me , this WILL WORK ON THE 920C. ENJOY...
hi,
above method is for SM-N920C, do you have solution for SM-N920T ?
No Idea, sorry, try different Custom Rom, i have not heard of this issue with the 920T. Good Luck.
