The problem is that you have no imei(you see for posts on how to fix it) otherwise upgrade to lollipop and STAY AT LOLLIPOP

problem was in latest lollipop update probably with new modem that blocked downgrading. actually imei was ok but I coudn't turn on wifi. I9515XXU1BOG3_I9515OJV1BOG3_XSG this version caused the issue, than I flashed I9515XXU1BOE3_I9515YXY1BOF1_ITV and after that kitkat, and everything works now great.
Bad movement, you mustn't downgrade a modem without backing up it or getting news about if is safe downgrading "x" modem to "y" modem. Try installign lollipop again, if this doesn't work, you need a jtag to reprogram the imei.
Experience upgrading and downgrading kitkat and lollipop modem (I'm lucky that I have a backup thanks to a automatic efs backup when I was installing the s5 rom).

I flashed PA 4.4.2 rom on my galaxy s4 and I did format system and wipe all the cache before if flashed the rom. Now after I flashed the rom i tried turning on wifi and it won't go on. It stay stuck on the off side and doesn't move at all. I tried reflashing and rewiping everything but that didn't help. I even put on different kernels and that didn't help. My data is fine so i still get interent from sprint. I would like to know if there is any fix to this problem?
Under about phone is everything mk2, baseband version, build number, software? What where you on before you flashed? Did you have the knox bootloader already? This is info you need to give when asking for help.

Hello guys.
I have a i9505 and it was running perfectly coolboy 4.3 GPE rom in old bootloader.
Then, I wanted to flash the brand new Jamal`s 4.4 GPE. And for that it was needed to upgrade my firmware to the last ML6 BL (Knox 0x1, but i dont really care about warranty). I flashed a MKE full package using odin, after I flashed ML6 modem using odin too, then Philz touch CWM and in the last the zip 4.4 rom.
It was fine, but i wanted to revert to 4.3 Rom because i didnt really like kitkat. and now my problem starts......
i flashed MKE stock package again, philz touch and then 4.3 GPE zip that was previously installed. After all this.. Everything works wonderfully, but the data.... it keeps dropping all the time! I tried everything... flashed ML6 firmware, ML6 modem, 4.4 Rom again, MKE stock again... nothing fixed.
To use data, i need to turn airplane on and off, but after sometime it drops again. When I select "only 2G network" it works fine too... but when 3G or LTE, it drops constantly...
Please, anyone have a suggestion... I really apreciate.!
Thanks in advance.
I had similar problems with coolboy's 4.3 GPE, the data just would not stick to "on", even on 2G. So I decided to flash Jamal's 4.3, and everything was great, on the very same modem! So I would suggest you to try that! Though it doesn't really explain anything! :silly:

thank you... but i can observe the problem running all kind of rom. I tried stock frimware, 4.3 coolboy rom, 4.4 jamals rom, CM11 rom, AOSP...
i dont think its related to any of them. maybe it is because of flashing modems and firmwares using odin.
Did you ever try to downgrade your modem? If not, then I don't see why installing latest stock ROM+Modem should not fix this!

Nope. ... I did not try this....
I dont see that either. Im used to do these flashing stuff. This is my fourth samsung phone, and i had never seen something that even a pure firmware flash didnt solved.
I looked for something related to knox triggered. But i didnt find anything that could blame knox for this.

I have issues with spontaneous rebooting on SM-N910C rooted phone. I have upgraded to Lollipop v.5.0.1 which was suppose to address this issue. I did a factory reset and cleared all cache and data from recovery mode. I removed my SD card and no matter what I have done the spontaneous rebooting continues. the Lollipop version is: Product code COD
PDA N910CXXU1ANK5
CSC N910CCOD1ANK5
using Odin v3.10.6. Is anyone one else having an issue with this version? Any thoughts as to trying a different version of the OS and which one may fix the problem. Thank you in advance.

Your bootloader and modem need updating to Lollipop. They are still on 4.4.4.

I have the same problem, and my bootloader and modern are definitely up to date. It seems to be modem related though, because often this occurs in combination with a total loss of signal!
so far I did not find a solution, this happens on stock kernel a well as on custom ones, and I tried different modems and roms...
I know this has been discussed and there are many post on downgrading from 5.0. The problem is there is more than one version on 5.0. So far the info I've found says the latest "upgrade" to OF1 disables Odin downgrades entirely. I've tried several methods for downgrading 5.0/lollipop
but odin always fails. Is there any fix for this?
So I kept throwing stuff at it and now it's soft bricked. I guess the question now is, is there any way ti fix this when Odin won't work?????
EDIT: I guess odin will work for for reflashing 5.0 or even back to 4.4.4 so now I'm back where I started.

Uhm. What? I'm OF1. Odin works fine. If you're having problems, you did something wrong or did something you shouldn't have done. Theres only one version of OF1. There's only one version of 5.0. If youre referring to root custom ROMs, once you upgrade from 4.4.2, root is no longer possible on the Verizon Note 3.That's all their is to it.

Yeah, I figured that out. I thought Odin wouldn't work because I first tried to flash back to 4.3 then 4.4.2. I then tried various other rooting methods and obviously none worked. The phone ended up soft bricked and it was then I found that I could flash 4.4.4 or 5.0. I had assumed Odin was disabled entirely with the locked bootloader.

Yeah. I did the same one time. Once you flash 4.4.4 or above it locks the bootloader. Downgrading won't fix it. Once it's locked, it's locked. Really sucks. I was working on a root method with some friends, but we all upgraded to the note 5 and S6EP... so it went to a dead stop. Too bad. There's about 20k worth of good donations for an unlock/root. Gl!
So I had DarkLord N5 on my N9005 before, which was awesome, but it had performance issues (especially when gaming). Then i downgraded to Stock KitKat using Odin and after boot up It showed No Signal, and everything was freezing and force closing. I somehow went to settings and found that i also have issues with IMEI and Baseband version, it was all unknown. The worst part is i did not backup my EFS. Any help guys please :crying:
I also have no audio playback
Im no pro here, but as i found in my research it is hard to downgrade from lolipop to kitkat as in 5.0 new architecture has been presented which they called art. I think. So it gives lots of incompatibilities. I tried the same as you but i ended up going stock lolipop for a while.
Yesterday i flashed Ressurrection remix 6.0.1 Marshmallow based off Slim roms and CM and i admit this is so far best rom i have tested. (Unless you need all fancy spen features)
I'd try to stick to anything that is 5.1 or above since great battery life.
Sorry for not much info, but i couldn't get past your post unanswered.

I had many experiences with downgrading from new version to old version with my S3 and my Note, but never had this issue. Something is causing this...
founded a old backup of CM11.. Flashed CWM and restored to CM. Works flawlessly, but still no sound and those stuff

So i had problems with my either s2 or note 4.
But afaik if u have updated your bootloader there may be no way to get back. And lack of IMEI on reverted KitKat isn't anything new. I bet going simply to anything art. Based will do.
People here are arguing on same issues as yours. Just don't listen to these "flash with odin" guys.. This doesn't work. Even if u flash the stock one.

Nope, I downloaded the KitKat firmware from Sammobile, and I'm downloading the Lollipop one now.

I tried it, but still no use :c
I would not try any other ROMs before trying to flash the latest stock rom from sammobile.com. Hopefully, this will resolve the baseband and imei issue. Sometimes, the missing or wrong imei is caused by a mismatch between the bootloader and modem firmware.

I did downgrading from 5.0 (CM12) to Stock 4.4 KitKat in my S3, but never had issues like this.
Downgrading from a cm rom to a stock rom via Odin can be fine because installing a cm rom does NOT alter the phone's bootloader or modem. Trying to downgrade from stock 4.4.2 to stock 4.3 with Odin on an s3 cannot be done.

Oh, never knew about this, thanks for the info
Sorry, I meant to say that installing a cm rom DOES NOT change the bootloader or modem. When you flash back to stock via Odin, you are simply writing over the existing modem and bootloader with the same bootloader and modem if you are flashing the same stock rom that was on the phone before installing cm.
I flashed between KitKat and LP official just fine.
