Back to "virgin" stock? - Sprint Samsung Galaxy Note II

Hi all,
I'm having issues with very weak WIFI (unless I'm 2 feet from the router). My wifes note 2 (never been rooted) works completely fine. Side by side, she has full bars and I have a small green dot. I've tried many different roms and nothing helped. I used [ROM][RESTORE][5-12-13]Back to UNROOTED Stock with Auto Flash Count Reset, so I can bring it to Sprint. They tested it and said that there is nothing wrong and I couldn't use my insurance to get another phone.
Reading throught the forums, it seems like it's a software issue. I even tried copying a 4.1.1 Wifi folder and that didn't help. I thought of trying the LJC version of the back to unrooted stock to see if that helps.
Anyone have any ideas how to fix this issue? Now my 3g/4g signal is very weak. Been downloading speedtest app for about 5 minutes.
Right now, I'm on Paranoid version 3.92/ TWRP recovery.
Any help is appreciated.
Thanks,
Randy

Forget it.
I found a stock image and was able to odin it to the phone. The phone went through multiple updates. Now my 3g/4g signal is alot better but my wifi is still weak. Now off to try to solve that problem.

[Q] No Service, No Data, WiFi Slow...

So, i rooted my phone today, bricked it a couple times, then fixed it(this doesnt matter)
Ok, so i was really excited to get this rom:
http://forum.xda-developers.com/showthread.php?t=864445
(I got the trinity, NOTthe Frozen one)
Long story:
So, I install the rom on my phone, no problems...but it seems I'm missing something and I've looked everywhere because i can't sign into Gmail, even with WiFi...Then again, I have no service...3g, or 4g, or for calling. Absolutely no bars in one of the strongest areas of my house. I'm thinking I'm missing some type of modem... I cant find it, I think i found it previously but from a different website, and they didn't even give instructions. Please help me because this is an awesome rom and I don't want to go back to stock rom.
Short story:
-no service, or data service, either.
-Missing some type of "modem" to enable data
-Airplane mode wont turn off. When clicked, it keeps going on and off. Please help!
Thanks in advance.
Not sure if this helps but I was getting major signal drop on 4g. Come to think of it 3g too. I don't think you are missing anything if it boots up and opens. Sometimes devs make tweaks internally that may not be known to us. I know when signal is constantly searching you get major battery drain
UFE (Unidentified Flying Epic)
Well, at least it's not just me.
For me the only way I've found that reliable works is to Odin back to DI18 and start from scratch.
Unfortunately, I basically can't touch CWM afterwards, because doing anything in it seems to bring the bug back.
Hopefully there's a fix out there for those of us that are continually plagued by this rather bizarre issue.
Seems rather strange that reflashing the modem with Odin doesn't even do the trick.
Just to.let u know you said you bricked your phone a few times. If you brick a phone it doesn't come back. You can't brick a phone a couple times. To answer your question sounds lime you need to reflash the.modem. go into.settings and about phone and see what your baseband version is. It should the same as the software you are on. If you are on dk28 then it should be dk28. Also I would upgrade to eb13 since dk28 is ikd school now and to many bugs that were not fixed. Just my 2 cents. Good luck

How to fix Call Dropping ???

I've had this phone about a month, and I can't have a phone call longer than 15 minutes without the call dropping. It has nothing to do with my location, because I have an Evo and older Epic in the same house and neither of them have a signal problem.
I have tried multiple PRLs and modems, including EL29, EK02, and many of the newer ones like FD19, FD24, FD26, FE07, etc.
Some of the newer modems were terrible, in that once I got loss of signal it would stay that way and I'd have to reboot. With EL29 and EK02, the loss of signal appears for only a few seconds, but when that occurs during a call the call drops.
seems like a weird issue, and looks like you have explored software related issues. One thing you could try is a network reset and force the phone to re-activate on the network, you will need your MSL though. If your device is rooted then you can get it. once you have your msl, go to the dial pad and do ## 72786#, it will ask you for your msl and should reset, this just clears out your programming information and should force the device to go through hands free activation. Not sure if it will help, but I don't think it could hurt.
Tried that also, same problem.
You stated that you've changed prls and modems. Have you tried any different roms?

I'm currently using Blazer 4.1 ROM.
One thing I've noticed, is if I turn off 3G data, then the Loss of Signal occurs a lot less often. Today I had a 40 minute call that didn't drop once I turned off 3G. Before I turned it off, I had 5 consecutive calls drop before they reached 20 minutes.
However, it's not a total fix, because I still get Loss of Signal from time to time with 3G off.
ever find a solution to this? this seemed to only appear when i went from a GB to a ICS rom.. but even after i flashed back to my GB rom/older modem, the problem is still there..
Ive had issues network related on mine. Certain roms well kernals mess with things that need left alone. Are you running one of the LOS kernals? I had constant issues with them. Try doing a full format then flash to stock unrooted eg30 then use ota up to ics. Then flash on. Ive fixed many issues with this method. IT seems when we flash flash flash it messes with it. But flashing back to true stock formated does seem to help

i'll try that, i do remember trying to flash back to stock ICS while trying to fix things and that did not help. i would have figured just restoring my old GB rom would fix things but seems the network issues were stuck.
Thanks

mobile network issues.

Hi,I just updated to 4.3 last week from 4.2.2 on my telus I317m. Since then I've noticed I can't get signal in places I could before. My data stops working even with full bars on 4g. If I turn off mobile and back on it will work fine for a bit then stop. If I wasn't 5 mins it will start working on its own. It's getting quite annoying to the point I might go back to 4.xx. Anyone have any issues with the radio(if I remember correctly)?
Is there any radios I can try? I haven't messed with radios since my desire hd lol. Any suggestions appreciated.

[Q] Network signal drop

Hello guys, first off I have an ATT S3 running the latest PA beta with quantum kernel.
Now my query, sometimes i have a strong signal and then it suddenly disappears, i mean from a strong signal to a no signal and it takes approximately 2 minutes to get it back again. My baseband is the latest anyways and i always have LTE on.
Btw even though i tried switching the signal mode it still doesn't work, any help would be appreciated thanks.
Sent from my SAMSUNG-SGH-I747
It has something to do with a LTE bug, many people have had it. I actually have it currently on my S3 with Quantum ROM.
From what I have found and read is that we have to go back to stock ROM, though it is "complicated" that it might brick our phones with an increased percentage... I am looking for guides on helping me go back to stock, but everything is so unorganized on here and many more experienced users don't like to help others who have problems. They just tell us what is needed without the aide that might help prevent a brick..
What I do know is that you need to go back to an old bootloader but you can't go back to an old bootloader..
I will be following this thread for some help, mine didn't get any help.
I have the same problem. Anyone have a fix?
I had the issue in the past. I fixed it by going back to stock with Odin. Some have said you can also fix by flashing a TW ROM. I have not tested it that way though.
Not sure but I believe going back to stock depends on which bootloader your on.

Nexus 5X: I Have Signal But No Data

I have signal but i can't use any data, internet, web services.
So i was trying out some of the available roms on my phone and they weren't too nice yet, so i decided to go back to stock. I used the skipsoft toolkit to go back to stock, and everything worked fine until i noticed that the mobile signal icon at the top wasn't showing anything other than the strength of the signal. I tried using chrome and hangouts but it kept showing up as no connection. I tried reseting to factory but the problem persisted. I took the sim card out and tried it in a different phone, where it did work perfectly. I was wondering if anyone else has encountered this problem and if anyone has been able to fix it. Thanks in advance for any help thats given.

Take a look at APN settings. Make sure it is correct for your carrier.

If you want to go back to stock wouldn't the best way be going to the google factory image website and download right from google and run flash-all from the bootloader
