problems after update to ROM 4.3

Hey All,
I have problems with my GT-N7100 after updating to rom 4.3, it's a weird situation after trying all solutions available online (all solutions I found ).
I will tell you the full scenario and please try to help me with it.
I was on rom 4.1.2 , after flashing rom 4.3 from sammobile, I started getting not registered on network, I couldn't solve it at first and I was afraid to try solving it by myself. I sent to service center and he said he can't make it work on 4.3 and it must be downgraded to 4.1.1 and he did it and it was working. I guess he installed a German rom , baseband: N7100XXALIH.
I decided to try upgrading again to rom 4.3 but first I took a backup by rom manager and then I flashed the 4.3 rom and the network problem happened again, the IMEI is correct.
I tried several ways including ariza patch and flashing several modems but it didn't work, until I found the way to flash: Patched_N7100_MK4_KERNEL then flash: Patched_N7100_XXUEMJ5_Modem.
That fixed the network problem and it worked super fine but at the same time I had problem with the wifi , it can't be turned on.
I tried Dr.Ketan wifi patch, but it didn't fix it.
I restored the 4.1.1 backup which I had at first but I still have the not registered on network problem.
I wanna run 4.3 rom and solve the network problem as well as the wifi problem.
please help me to solve this problem.
PS: I bought this phone last year from HK and I flashed 4.1.2 rom for Egypt right after I bought it and it was working fine. now after I tried rom 4.3 for Egypt, UAE, and HK I'm still having problems.
There is a service office said he can solve it but it's gonna cost around 40 USD, I wanna save that money and know the solution by myself to be able to solve it if I face it later.
Sorry for the long thread. your quick help is highly appreciated.
Thanks

For IMEI do a EFS backup. For Wifi, flash mj5 bootloader.

Make sure USB Debugging is enabled.

well , I successfully fixed the problem, but now i have a question, I installed my rom from sammobile, did wipe data,cache , dalvik. but still my device status is custom. how to make it official ?!

Please help me, it's urgent. My Note 2 became a tablet..

Two days ago i bought Samsung Galaxy Note 2 N7100 (international). It had android 4.1.2 but i saw there is available update. After update to official android 4.3 my phone lost signal and started showing me "Not registered on network". 1 day passed since i am searching how to fix this thing. Tried custom rom (4.4.2) and still the same. I went back to official 4.3 for UK O2 , successfully rooted it, passed knox, installed busybox, installed ARIZA Patch. Still the same. Tried to flash MJ5 bootloader via ODIN but it shows me FAIL. And after every FAIL my phone is bricked so i am flashing all over again official ROM. I have NO backups of my EFS (in my search i saw that i need some EFS to repair this thing). I got no issue with WI-FI but only with network. If i revert back to stock android 4.1.2 will i be able to call somebody? If the answer is "YES", would somebody tell me how? I saw in some threads that with new 4.3 ROM note 2 got knox locked bootloader which is impossible to be downgraded. Please, give me guide step by step what to do to repair my phone by myself. Thank you in advance.

I would suggest you to take an efs backup on 4.1. Then flash 4.3 and if you aren't getting network try restoring your efs backup. That might solve your problem.

[Q] downgrade from 4.4.2 to official 4.3 can i use Odin?

Hi guys,
i'll sell my 7105 in few days so i'd like to set back official rom!
my only doubt is right now i'm using custom rom on 4.4.2 can i just wipe all go in DOWNLOAD mode and install 4.3 official rom?
about keeping the root ?
thanks

Yes, Odin is the way to go. You don't necessarily have to wipe anything, but I would do so to make sure it is factory reset and to prevent you from boot loop.
Flashing stock will unroot the phone, but it won't reset the flash counter! Consider to do that as well as you are going to sell it.

thanks Yakobus for your reply.. actually i did act before reading ur msg
well i was just scared to destroy note 2 just few days before leaving me ahah!
FYI , for those like me willing to know, this is what i did...
I've got latest rom from sammobile..
I used trianlge away and then i went in recovery over my phone!
once in recovery i wiped ALL.. and i mean all with TWRP recovery!
from there i rebooted phone in DOWNLOAD mode and i used ODIN pc (u can find step by step by Dr Ketan or other post)
flashed 4.3 to my phone, when rebooted everything was working ( yes also wifi )
COUNTER went back to ZERO ... Knox is installed (apparently) but honestly i couldn't care less..
everything good if anyone has some doubts.. ask
:highfive:

You are welcome. Good to see everything went fine and thank you for the summary!
Edit:
What I did not have in mind: Your Knox counter is probably set to 0x1 as you were using a custom ROM. You cannot reset it so far and I do not know what that means for our warranty as it depends on your country's laws and your provider/seller.

with some more details pls , i'm a noob , had note II 4.3 JB , upgraded to 4.4.2 official kit kat and want to downgrade , i didn't root it , i didn't do anything at all and i dont want to lose the phone i just bought a week ago , can u help me?

Need advice n7105 strange knox bootloop with every rom but 4.1.2 stock after cm10.1

Hello,
I'm a noob but usually try to fix this kind of issues on my own, looking at the boards, following tutorials, learning, but this time I think I'm not able to find a solution on my own so I'm asking for advice here.
Some time ago I installed cyanogenmod 10.1 on my Note 2 LTE and was happy with it for some month, than last week I tried to upgrade to cm12.1 It worked but there where some issues and bugs, mainly I wasn't able to swap internal/external sd cards.
So I decided to go back to latest available stock rom 4.4.2 from sammobile.
Here is where the problem starts. The stock 4.4.2 resulter in a bootloop, tried cache/dalvik/factory reset, flash again, whipe again.. nothing.
The phone is not able to get past the white label "Samsung Note 2 gt-n7105" screen. It goes black than the white label again and again.
It doesn't even get to the Samsung animated logo.
Ok bottloop, no problem, try to flash again something else.
I tried different Custom roms, different kernels, different flashing methods. I can flash anything with no problem but every time a get a bootloop.
During the various attempts knox fired, but I don't care. I don't know if this could be the cause.
Actually the only firmware that works is the original oldest STOCK 4.1.2, every other stock firmware past that or any custom rom is bootlooping the same way. To fix I only can reinstall stock 4.1.2 with odin.
I really need any advice or hint.
At the moment my goal is to get at least to stock 4.3 but I cant.........
Thanks!

When you first bought your phone, did it come with Knox?

nope it doesn't existed before, but now I can see it when I boot in download mode "knox warranty void:1"

Try to get the latest firmware available via kies ,that worked for me

From what you've described, I think the Stock ROM 4.4.2 from Sammobile contained a bootloader update. So when you flashed this ROM, it updated your bootloader from the non-Knox version to the Knox version.
I am very unfamiliar with the technical details of Knox, but I think the new Knox bootloader is causing your bootloop problem.
However, I don't know why 4.1.2 works when everything else doesn't work!
Can you check the Stock ROM 4.4.2, and see whether it really contains a bootloader update?

I think so, there is a boot.im, anyway I also discovered that I can flash cm10, 11 and 12 with no issue too..

Since a boot.img is present, it means that it would flash your boot partition. So now we know for sure that when you attempted to flash the Stock ROM 4.4.2, your bootloader was changed to the Knox version.
So the lesson here is: before you flash anything via ODIN, always check to see if there is a bootloader update. Usually you don't want to be changing the bootloader on your phone.
***
So now there are 2 possible ways to reach your goal:
1) Keep your new bootloader and see whether you can get Stock 4.3 or Stock 4.4.2 running on your phone
2) Try to restore your old bootloader
As I said earlier, I'm not familiar with the technical details of Knox, so I'm not sure how to get Stock 4.3 or Stock 4.4.2 running on your phone when your Knox indicator is already 0x1. You need someone else to help you.
And you can only restore your old bootloader if you happen to have made a copy of your boot partition before you flashed the Stock ROM 4.4.2. Even if you did have a copy of your original boot partition, I'm not confident with helping you to restore your old bootloader. You need someone else to help you in this case too.
Conclusion: I don't think I can help you to solve your problem I'm sorry. Hopefully someone else who is more of a pro than me will come along to help you out.
Good luck!

Impossible to downgrade N910H to kitkat 4.4.4 **challenge**

Dear friends, it's the first time that I write a thread seeking your help.
I purchased my note 4 N910H 5.1.1 few weeks ago and I discovered that battery drains in a horrible fast way even if it is turned off (6 to 7 hours max). I read that many people had the same problem and that after a downgrade to kitkat this issue was solved. So I decided to do so.
I tried all methods I found on forums; all files I found on sammobile. No success.
I only could install 2 files..
1- N910HXXU2COJ4_N910HOLB2COJ2_N910HXXU1COJ2_HOME.tar is a 5.1.1 with CSC from Cambodia (CAM). I don't think it is the good one coz after installing it I could not do an update with kies (shows an unknown error).
2- N910HXXU2COJ4_N910HOJV2COJ1_N910HXXU1COJ2_HOME.tar is also a 5.1.1 with CSC from Iraq (MID). With it, kies accepted to update firmware without problems, so I think it's the good one.
I also found a 4 files ROM N910HXXU1ANJ4_OLB1ANJ4 it is a kitkat ROM but can not be flashed (Odin shows nand writing error). I tries to flash this rom without loading Bootloader file.. it worked but phone was stuck on a bootloop and could start again only after flashing 5.1.1 ROM.
I think that bootloader is locked or secured somehow and refuses all roms.
What is the solution? is there an other kitkat ROM with same actual bootloader maybe? is there a way to change bootloader version?
