SGH-I727R Help ?

Hey all !
I've bought a Samsung Galaxy S2 from Rogers, here in Canada. The model on the box clearly states SGH-I727R. I've managed to get it rooted and I've installed Sky-ICS 7.04 custom ROM on it. Everything went fine but I'm having a small issue.
The 4G signal keeps dropping. I can call just fine but about 10-15 seconds after the call ends, 4G drops and I can't use data anymore.
Everytime I want to use the Internet, I have to make a call first then I can use it but as soon as my phone goes on sleep mode, 4G shuts down and I've got to do it all over again. I've tried calling Rogers Tech support but they told me I'm registered on the network and that I should normally be having signal.
I'm pretty sure this is a newbie question but I'm new to Android and I haven't found much help by searching the forums so far.
Edit : The "Turn on Plane Mode" thingy doesn't work at all. Also, Rogers Tech suggested to manually search for a carrier and select Rogers but that didn't change a thing. Also, selecting Automatic Mode doesn't do a thing.

search for forums for the darkside script, and the ucla3 modem. reboot into cwm amd under mounts and storage format cache, data and system. Then flash darkside. Then ucla3. Then skyics. Reboot and let phone sit for 20 min, then reboot again. report back to us :-D

Been a couple hours now and it's still up and running. I'll post results tomorrow morning.
Thanks a lot :-D

I'm guessing my instructions worked then. Hit that thanx button bro ;-)

I let my phone recharge overnight. When I woke up this morning, it wasn't working. Rebooted, still wouldn't work. I had no use for it so I let it sit on my desk till I got to work. As we speak, it appears to be working. It seems intermitent but it works twice as often now O.O
What I did :
- Flashed DarkScript
- Flashed UCLA3 Modem (How come is that file like 350mb?)
- Flashed Sky-ICS Speed 7.0
- Applied Sky-ICS 7.04 Update
Anything else I've missed ? I've seen another post where someone explained the same thing but with UCLA3 Kernel + Faux Kernel. Should I try that ?

ur flashing a ucla3 rom lol, the radio is only 20 mb. Ur flashing a rom ontop of another rom, no wonder its not working

I dunno, I did a search on the forum for UCLA3 modem. Ended up with that file, which is weird because I was expecting a smaller file too. Do you happen to have a link to that file ?

Search for this radio " REX_MOd_LA3" and give it a shot..

Now THAT was quite helpful

Nope. Still no luck. Flashed DarkScript, flashed UCLA3 Radio then Sky-ICS 7.0 and 4G still drops randomly.
Not sure what's left to do at this point ...

This seems a very useful topic (at least to me )
So what is the sequence of flashing? :
1. ROM
2. script
3. radio
Do we have to wipe the data every time we flash each of those

Are you doing the wipes that were suggested?
After all this flashing and running different stuff you've probably got loads of crap in your caches.

I believe the order is
1. Script
2. ROM
3. Radio
but I did Script, Radio THEN ROM, which I believe is incorrect, unless I am mistaken

Yes, I did the wipe as suggested. Anyway, I think DarkScript does it for you aswell.

You just need to start over, wipe, Odin stock.

That guy has a history of trolling
And I agree with xcrazydx, I recommend starting over. Hopefully you didnt start adding apps and customizing yet. If so use TB and restore it later

Reinstalled Stock Rogers ROM. Did all previous steps. Tried to flash custom Boot Animation instead of TPC V3 animation (Yeah, I switched from Sky-ICS to TPC as I thought I'd check if it is ROM-related...). Phone was stuck on Boot logo for a good 15 minutes. Pulled battery, re-flashed using Odin + Stock ROM. BSOD while flashing.
Go Windows !
I'm re-flashing using Odin.
I'll keep this thread up-to-date as much as possible.
Edit : Flashing worked. Yay for unbricked phone !

The last two steps are independent of each other. It doesn't matter.
Start again from stock though.

Seems to be working so far under TPC V3, starting from Stock ROM + DarkScript. 4G icon disappears when under WiFi(Which is normal, I guess) and reappears whenever it uses 4G(SMS/Call).
Problem solved, so far ! We'll see how it's going tomorrow
Thanks a lot to everyone for the help, really appreciated. Great community !

Wipe Cache/Dalvik and data.
DON'T use the device after the first boot, let it just sit there alone for 10 minutes, reboot it and start using it after, works for me everytime, i guess it's just cache regenerating all over again which can cause slow performance and can get corrupted sometimes causing freezes.

Did you follow the steps ONE BY ONE on the CM9 thread? you should use the flashing from stock method, all of the steps.
If you did that, try another base rom (XXKPU) and then flash CM9 on it.

If it was working fine before you turned it off, it's probably not a brick.
Maybe it's a hardware failure?
Try using the reset button between the speaker and the camera and try to turn it on (Search to find pictures about it).
If that doesn't work, keep trying to access download, if that also doesn't work, it's probably hardware related, although that in my opinion would be weird.

[Q] Please Help my phone reboots when connected to network

Hi,
I have rooted my phone and flashed with RemICS -UX 1.0 directly from stock GB 2.3.5 and there was no issue. Then I flashed again with 1.5.3 and 1.5.3 fixed (later) and from this point onwards it starts showing issues. When I turn on mobile data, it will automatically switched off and not able to turn on untill connected to charger or USB. Then I continued flashing with different ROMs like CM9/CM10 Alpha,RemICS -JB ,RemICS 1.6 etc. But the same issue persists. So I flashed with stock ROM. I have first flashed to XXKPE and then to XXKPU using Odin as given in the following link
http://blog.vigitalsolutions.com/2012/08/18/upgrade-samsung-galaxy-sl-i9003-to-cyanogenmod-9-cm9/
The issue is there in both the stock ROMS and it got worse. Now whenever it got network signal the phone will be turned off. If I turn on again, then it will be on for sometime and if a call came, it will turn off. I tried everything. wipe cache,wipe dalvik,factory data etc. But no use. Now don't know what to do with this phone.
Please help

Hi! I see you are a new member, perhaps now is the best time to read the forum rules, not that you violated or anything.. just wanna inform you.
Anyway, do a factory reset.. if that does not fix it, flash a stock firmware, not just a stock rom.. flash the whole thing, and of course, do a factory reset
Hope this helps, do report back for your feedbacks! Cheers

hmm....but nothing is fixed yet. The phone is turned off in between calls or if mobile data is turned on. When I try to turn it on again, it will show the boot animation and is shutting down. It will turn on again if I connect to charger. Then will work until i get a call. It will turn off during the call. don't know what happened actually. I shouldn't have done flashing

Someone please help me.Is there any possibility of getting my phone back to normal behavior ? Very much frustrated as I cannot read news and all .

This same case happened with a friend of mine
He was on CM10
WHAT I DID :-
-Factory Reset>wipe cache>wipe dalvik cache
-then i flashed ddlf2 2 times
And now everything is working fine with him !!

Thanks bro. I will give a try. Also is it needed to enable USB debugging before flashing.. ? I doubt that it was disabled for me when I do the flashing.

[Q] wifi issue on JB roms

Greetings guys. I'll skip the bs and tell you what my problem is. I just rooted 2.20 like everyone else and everything has been mostly fine but when I flash any JB ROM my WiFi doesn't work. I've tried flashing different stock ROMs in which the WiFi does work then wiping from recovery and reflashing jb but no dice. I've also tried fixing permissions and every other solution I've found via search.
Making a thread is a last resort as I know you guys are being flooded but any help would be much appreciated.

Try the 10/25 experimental nightlies CM10. Have heard this fixed wifi issues with most people

Any jb Rom? Are you having the same issue on aokp or miui

Does it say error? When I'm on jb I have to try to connect it like fifteen times than it finally does

I don't get any errors. It just doesn't pick up my router. Although when I disable all security on the router it picks it up just fine. A totally unlocked router is out of the question though.

Yeah. I spent a good long while tinkering with my router and even factory reset it as well as tried every security type, changing ssid, hiding it, the works. My old iPhone picks up the router just fine, as does my laptop. This leads me to believe the problem lies with my phones ROM. I'm gonna try to flash a couple of the ROMs suggested to me once my phone charges.

So Ive flashed the experimental CM nightly released on the 25, MIUI v4, AOSP Nocturnal Dirty Rom 4.1 as well as AOKP JellyBean. Still nothing. Im sure I'm forgetting a couple too.
Don't really know what else I can do at this point. Ive tried different gapps packages too just in case that could be it. I might have to abandon all hope of running project butter right now. :crying:
Damn shame too, I really really like AOKP JB

It doesn't recognize it at all. Unless I completely disable any kind WPA/WPA 2 security. Back on stock unrooted Sense it would pick it up just fine though.

that sounds like a legit issue, you should probably report that to h8rift in the cm10 thread and see if anyone else has the issue.
out of curiosity what type/brand of router do you have ?

Update: Now running Cleanrom and everything seems to be working properly. I'm gonna stick with it for a little while until I can figure out how to run JB with wifi.

I had an old D-Link and wifi worked fine on JB based ROMs for me.
a WBR-2310A to be exact

I've had the same issue in every aosp ROMs however on my phone i do get the WiFi to work. It takes me a while but I eventually get it. What I do I turn WiFi on and off, leave it off for a minute or so, re start my phone, after phone starts I turn WiFi on and most of the times it does it, you have to have patience

Depending on ROM an kernel, WiFi scan intervals are up to 5 minutes apart.

[SOLVED] WIFI will no longer turn on

Hey all,
I installed several custom ROMs and WiFi would no longer turn on. In an attempt to restore it, 24 hours of disaster later I have a completely stock image on my phone. Nothing changed, and wifi still will not turn on. Everything I have attempted has not worked. It was working just fine until I installed SlimKat ROM. Any ideas on how to get working wifi again, or at least a method to test if it is now a hardware problem or software?
