Data problems when flashing JB Roms!! Help please! :) - AT&T Samsung Galaxy Note I717

Hi I hope someone can help me with this issue. So far I have tried JamieD81's and ManelScout4Life's JB roms for my note and both times after about a minute of having "4G" coverage, it reverts back to HSPA or HSPA+ and it will show 3G for about 2 seconds every now and then. I have tried toggling LTE off and it works for about another minute then back to HSPA. I have tried resetting my network provider and that does the same thing. In some cases my data would turn completely off when using JamieD81's rom. I would really like to try and use one of these roms as my dd but with little to no data speeds, it's impossible. If someone has had this problem as well or has a solution please, please help! It would be greatly appreciated.

Had this problem myself too...

Do you have any ideas on how to fix this or what causes it? :/

3G CDMA disconnecting during high data download

Hi,
I have been facing some strange issues from the day i got my photon,
My 3G CDMA (EVDO) works fine in normal scenario (with normal web page viewing) but when ever i try to do large file download / try watching youtube with HD video the EVDO gets disconnected and i think the radio re-starts after around 1-2 mins and the data connection is up again.
Same thing happens if i try using speedtest (may be that also tries to send big chunk of data to test BW) and when i try download big files of more than around 5 MB in Google play.
When this data disconnection happens in my EVDO signal bar only upload arrow is being shown and no download.
This issue is persistant in all the Rom's i tried (have faced with Stock/CM7/MUI/CNA/CM9).
Using the photon in CDMA with Reliance in India.
Pl help me to get the issue resolved
Might just be an issue with your service provider.
I wish I could watch youtube in HD lol

I don't think its a problem with service provider as the issue is not present in my friends mobile (Samsung)
Dumb question but, did you make sure that you dont have data saver enabled. I had it enabled from Sprint and had an issue like that. Its under settings--> battery & data manager--> data saver

Had checked that earlier, It is not enabled.
Just to check just enabled it and checked same issue
Some one pl help
If this has happened since day one, the n you should flash stock on it and turn it in for a replacement because it sounds like it might be a hardware issue. Its obviously not a software issue since it happens with so many variations of roms.

I think issue is not seen if i use GSM 3G NW. But it comes up only with CDMA EVDO

If you're sure that when flashing the other romz you appropriately wiped data, system, cache, and dalvik I'm inclined to agree with fugitive. I would flash the latest sbf and see if the problem persists. If its still there, get it traded for a replacement as your issue isn't normal.

That could just be an issue with their network in india then, but just to make sure, are you using gsm or cdma networks, because it could be a gsm issue. I would think cm9 would be your best option seeing as how they have more gsm support

[Q] 3G To HSPA+?????

Sorry to be a bother. I have serached numerious post about simular problems with details pretaining to a fix in this matter. I have a Samsung Galaxy S2 SGH-I777. The Rom I am currently running is ShoStock V.2.2.6, Android 4.0.3 with the cheerypicker Kernel and bandband ver.I777UCPLCS. The problem I have been having and did not have before flashing this rom, is that my 3G signal and HSPA+ notification keeps flickering back and forth. Plus my data speed have slowed up a bit. Yes, I could flash back to another rom but I really like the features of this one. Is there a fix to this problem is it a known problem? Thanks so much.
Try a different modem.
Also H+ only shows when using data, if not it will show the 3g instead.

I figured that LiLChris. But it keeps flickering back and forth. Plus this is mow happening in areas that I once had a full H+ signal with very fast speeds.

The flickering is part of ShoStock and most other ROMs. It shows you the true connection; as LiLChris said, it uses H+ only when using data, and defaults to 3G when no data is being sent. AT&T usually just hides this and makes it show H+ all the time, even though that's not accurate.
I know, it freaked me out at first too lol. As for data speeds, try different modems and also changing APN settings.
EDIT: I didn't know the problem was when you're sending data (you posted a couple secs before I did). APN settings and a different modem may help you out with that.
Sounds like modem issues as stated. In my area modems can vary by up to 2mbs depending on which one I try

Is flashing different modems cut and dry? Is there a place to go and see what modems in my area are good to use?

Why is my works WiFi is fso slow when I have good signal?

It Works ok if im less than 5 meters away from server. But anything over that and its unusable. I work about 10 meters from the server. And I get at least 2 - 3 bars of signal out of 4. And I can't even post a comment on here. The speed is very fast for about 30 seconds and then ridiculously slow. It also struggles to connect. Tries about 3 or 4 times before it connects. I'm running cm10 on s3 but have this problem on stock, omega and checkrom. I had simular problems with the s2 aswell but not s1. I don't want to use wifi kill as its my work and it might not solve the problem. Is this the s3 working on networks with multiple apns? Is there a code I can call to turn off power saving ?? Can't force to 5ghz either.
Some advice would be massively helpful. I am getting very frustrated.
Thanks in advanced

I believe the problem lies in network or in the wifi router. Maybe it's overloaded, try on-off cycling the router and see if it works then?
I kinda doubt that the issue is in the phone
I've fixed it now mate. Well chuffed. Don't know what it was really. But the method I used in above thread worked. It all started when I first rooted and flashed omega. Cm9 got rid of the authentication error (so it seems Sammy is at fault there) as for the WiFi range of about 3 meters and no connectivity after that distance. I'm not sure. Perhaps a problem deep in the settings I could not find. But completely wiping all settings worked. Not ideal. But confirmed working all day at work. So maybe a omega fault I don't know. Jus happy to have fixed it

It can be many problems! Maybe the ROM that you are runing has poor Wi-Fi support or maybe the phone is just "getting old" or maybe its the Wi-Fi set that sends you the signal!
I got a s3 which is not old but I've fixed it now. Thanks

No Network Coverage - Res Remix Rom

Installed res remix two days ago it was working fine network coverage seemed fine... then I woke up and I had emergency calls only no signal... Tried re-flashing didn't help. Tried a stock rom and it still didn't work.. simcard works fine in friends phone, and a simcard on the network Three works fine in my phone :/ so i'm abit lost at what to do, I'm pretty new to all of this so please ignore my stupidity lol
I think it has something to do with the baseband or modem

i've tried different modems and the phone works on a different network sim would that still cause it
Search the thread for a modem of your region and try a few till you get one to your liking. Takes a while for the phone to get 'used' to a new modem so even if it isn't the best at first, the signal tends to improve after about a day or so. I have never encountered problems with signal but I hope this helps

I've had this problem too, so try this. Click on roaming, and if that doesn't work, take you sim card out and put it back in, and see if that. good luck! Ultimately I think it's a card problem, and if it happens to me again, I'm going to Verizon and getting another sim
