Hi,
On my Note 2 7100 , I have given my phone to service centre guys to upgrade to 4.3 from 4.1.2.
After they attempted to upgrade the phone is not booting
The system status says Custom and they say it because you have rooted your phone and we cant help.
But before I gave my phone to them I have checked the phone there was no super user also every screen was looking official.
So I am not really sure if my phone was ever rooted or they screwed up my phone.
According to them if i install the old firmware my phone should boot.
But since I have no idea how it was rooted i am not able to do any thing.
Please help ... Urgent

Flash a custom ROM using ODIN Guide here. dun use the odin in the description. It's outdated. use this instead. Flash a custom ROM (or official) (official 4.3 has kies though) If u wan 4.3 without bloatware, try this.
Hope I helped!
which rom should i use
Hi,
I have tried to flash it with stock rom but its not booting.
Which rom should I use to flash the device now ?
Keep pressing buttons continuously for download mode
Then the upgrade failed message will go and then it will enter into download mode. after this you can try again.

Do a mega wipe (if u dun mind). The service guys may have put in a wrong modem so, flash a modem for ur phone. Download ur modem here. This fixed my phone 5 minutes ago when i accidentally flashed a N7100 ROM (Ditto Note 3) on my N7105.

How to SIM unlock and/or roll back firmware on Samsung Note 2 N7105.
This is how I did it. It worked for me. That's all I can say. It may or may not work for you. I'm no 'expert' so I can't answer any tech question. I found this by trial and error. None fatal. ( So far) I will take it for granted you know how to Root and use Odin. I'm also assuming you have installed the Samsung USB Drivers.
http://uploaded.net/file/xdloq4jw
If you are using one machine to do this remember to disable Kies before using Odin.
My phone was updated to 4.3 using Kies. I did this on my laptop as I didn't want Kies messing up anything on my computer that I was going to use for the rest of the process.
So stating with a stock phone.
Using Odin
http://uploaded.net/file/o2xcp01n
I rooted my Phone with
CF-Root
http://download.chainfire.eu/255/CF-Root/CF-Auto-Root/CF-Auto-Root-t0lte-t0ltexx-gtn7105.zip
I then downloaded SuperSu from the market and ran that. It runs a fix to stop Knox.
I then installed ES File Explorer from the market.
Then I downloaded My Phone Explorer. I like this program and use it a lot.
http://www.fjsoft.at/en/
Using ES I backed up my EFS folder to my Sd Card
Using MyPhoneExplorer I backed it up again to my computer.
Better safe than sorry.
I then used Odin again to install the 4.1.1 Firmware.
I got it from here. There's 4.1.2 there as well for those that asked.
http://www.sammobile.com/firmwares/1/?model=GT-N7105&pcode=EVR#firmware
I then installed 4.1.1 by unzipping the file and using Odin.
I then use CF-Root again.
Using the *#Codes as below
Step 1. Insert a SIM on your Note 2, you should find the familiar “SIM network unlock PIN” window.
Step 2. Dial “*#197328640#” on your Note 2 to enter special menus.
Step 3. Choose “UMTS”.
Step 4. Next choose “Debug screen”.
Step 5. Choose “Phone Control”.
Step 6. Choose “Network Lock”.
Step 7. Choose “Perso SHA256 OFF” and wait about 30 seconds.
Step 8. Press the Menu button then choose “Back”.
Step 9. Choose “NW Lock NV Data Initiallize” and wait about 1 minute. *Then reboot your Note 2.
Step 10. Once rebooted, you should no longer get the Network Lock window any more and you should be able to get signal and data. *If you have trouble getting 3G/HSPA+ data, try setting the APN to your carrier’s settings although it should set automatically.
I did try this using 4.1.2 but Step 7 was missing.
I then updated back to 4.3 using Kies on the laptop and then CF-Root again through Odin on my computer. Fixing Knox by re downloading SuperSU and running that.
One SIM unlocked phone.
I then used Titanium to freeze all the Samsung and Google stuff I didn't want and also froze Knox.
MY phone is running stable and good. Auto update though says it has been modified so now it will not OTA. Which isn't a bad thing.
Thank you to the respective developers of the software I used.
I hope this helps others.

I got the same problem,after updating to 4.3 version my phone asking for Sim network unlock PIN.
You mean flashing 4.1.1 from 4.3 got no failure?
Currently downloading 4.1.1 version..after attempting to flash 4.1.2 it failed in Odin,due to a new bootloader
Edit:
Confirmed I successfully flashed 4.1.1 and successfully unlock network.
Tnx dude!

Absolutely no idea mate. I only tried it on my phone.
ive been looking for this
im having the same problem and hopefully this fixes it.
but about the updating to 4.3 using Kies, wont it trigger the SIM network Unlock Code again?
Hi, what android PDA did you have before doing the downgrade. I have read some posts that say that you can not downgrade if you have MK4 or later... I have a Galaxy note 2 GT-N7100 and I would like to test what you did with mine, but I'm not sure if its possible
Regards

The menu code doest lead me to the Perso SHA256.
After the Network Lock menu it says Command don't exist or something like that.

All I can comment on is how I did it on mine. I don't have any other phone. Sorry.
Maybe try the UK one that I used. Once it's SIM unlocked you can put a local to you ROM on.

Hi,
I followed the instructions properly. I rooted my 4.3 with CF auto root, and then I tried to flash the 4.1.1 firmware onto my phone.
Now it is stuck at the boot screen, and I'm so shocked because I did everything correctly.
I can still get to "ODIN Mode" by holding volume down, home and power, and it says:
Current Binary: Custom
System Status: Custom
Knox warranty void: 1
What have I done wrong?
Thank you.
help me !
i have a Note 2 N7105.i did the exact steps.on the notification bar, i can see that i have signal, the phone is unlocked, but still, i cant use the network. it says NOT REGISTERED ON NETWORK. what do you think is the problem ?

I must say.... you are my SUPER STAR..... I have search everywhere and looked every corner of the website..... apart for paying around £20 to 40 to unlock the phone from someone... you have made my day.... I have been trying to unloack a phone that I have bought from ebay... it was locked to EE network in UK, your way of downgrading the firmware to 4.1.1 and use the code “*#197328640#” had worked... the phone has been upgraded wot 4.3 Jellybean, and the code does not work at all. However after down graded to 4.1.1 (as you have done) , I was able to use the code “*#197328640#” and unlock the phone, then I upgrade it back to 4.3 and now doing a firmware upgrade to 4.4..... the network block has ceased... so I guess the phone is now completely utterly unlocked forever....REALLY Thanks to your logical trial and error...
I must say, it took me some trial and error to reinstall the stock ROM, whick I had to use Philz recovery to completely clean up the device before I reinstall the stock rom.....
Any thanks again, and when I get a chance, I'll post my steps which had worked.
Cheers Mate,
Dave
Am glad to hear that
works great
Big thanks to BorgCymru for the how-to.
Just got a n7105 that was locked on EE/Orange (UK) that had KitKat 4.4.2 installed. Followed all the instructions but used cwmrecovery (to make backup rom) and it worked great for me. Tested with tesco, 3, o2 sim and all work.
Only thing to add that after installing firmware 4.1.1, the phone went to reboot but the screen became locked on the 'Samsung' logo. I removed the battery and booted into recovery to wipe partition and wipe cache. Rebooted and all was fine.
i been having issues unlocking with running 4.4.2 indeed to downgrade was the correct step, i am now unlocked
I know you posted the original post a while back, however I purchased a note 2 7105t off eBay and it was locked to Vodafone Australia. I actually got a code off their unlocking site and of course it did not work. I then contacted their customer service and waited 4 days for a call back with a unlock code and master reset code, once again did not work and I was told to take it to a Vodafone shop and they will send it away. One again, brick wall, as the shop said, "have you a proof of purchase from Vodafone". Nope I do not so they refused to send away and told me I was,"stuck with Vodafone".
Now I want to thank you for assisting me in unlocking my galaxy note N7105T 4.2.2 with your information. It worked like a charm.
The only question I have is if I now put an update firmware from 4.1.1 will the lock come back on? I see here a couple of members said they were fine, can I get verification on this please.
Hi Tamate. Once you unlocked it is permanent.

No so... Did that way back, and last it while travelling, it locked itself! Still trying to find a way to unlock it (I'm now on Marshmallow!) Afraid downgrade back to 4.1.1 will do more damage (bricking the phone for good!)
BTW, how can I tell if my bootloader ever got upgraded?
Hello fellas! It's my first post here, but I've been a member for quite a while now. Anyway my question is how do I update my Samsung galaxy s3. It's an At&t s3 but I use T-Mobile on it. I'm stuck with the 4.1.1 because I can't update it. Whenever I try it says software update interrupted check again in 48 hours. I did search through the forums about this and someone fixed this by using another sim, I tried that but it didn't work.
A couple things to note, I did root my S3 with the cyanogenmod but I went back to stock rom and did the triangle away. I also unlocked my phone using that dial method. Please help me guys. Thanks!
Oh and here's a picture, the continue update is grayed out.

You have 2 options ...
1) Find a valid AT&T SIM and temporarily place that in your phone to get an OTA update via Wi-Fi
2) Install custom recovery (TWRP or CWM) and manually update to 4.3 using the stock restore image posted in the thread below
http://forum.xda-developers.com/showthread.php?t=2658486
This will unroot your phone (if currently rooted), update your system to full stock 4.3, reinstate stock recovery and reset your flash counter.

Thanks Larry. I tried using another sim before and it didn't work. But then again that sim wasn't At&t. Hopefully the first option works. Now I'll have to look for an At&t sim card.

Using an AT&T SIM should be fail proof to receive the OTA.

Just to add that OTA update could take anything from 30 minutes to 2 hours depending on the speed of your Wi-Fi connection so if you are 'borrowing' someone's SIM, to have an idea of how long you'll be needing it.
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.
firstly i apologise for my basic knowledge of this sort of thing, help would be greatly appreciated.
my unlocked at&t galaxy i747 recently was repaired via jtag after an over the air update bricked it.
i got it back and after an hour my sim wouldnt connect to the network anymore and i noticed the camera didnt work.
the guy who fixed it told me to wipe the devlik cache and factory reset which i did but i still had the camera and network issue.
i was hoping to flash back to stock rom so i cleared the current rom with the philz recovery and tried to install a stock on odin but it failed.
my main issue is that is if i have to send it back id like to with a rom on it. so if someone could provide me with a rom that will work id be most thankful. if i recall he installed a custom rom that said it was on the 4.1.1.1 version of android. the baseband wasnt ucdlk3 like my stock roms on the pc i tried to flash were. it had numbers like ...m j b ?
after i do that im hoping the guy will tell me how i can fix the camera and network issues. id rather have all stock rom and such but i dont want to interfere with that hes done.:crying:
i have a 16gb storage card so i can install the rom via zip if necessary. thanks for reading this, alex.
also i dont know if this is important but then i click turn off in recovery it says root missing.do you want to root? i just always click no.
Well if your on mjb then you can't flash to 4.1.1 or anything below 4.3 as the efuse has been triped and won't allow any other boot loader to run resulting in a brick.....so if you can flash 4.3 firmware to your phone and see if you can get it to boot.....if you can't then you may need to unbrick it with either the sdcard method or a JTAG again
