Hi bros

First of all I am not a developer, the EFS folder of my Note10+ was deleted by mistake and I lost my IMEI numbers, after a lot of concern, researches and tests I fixed my Note10+ and I want to share my very hard and bad experience maybe someone will need it, so I will not be able to assist you or answer any technical questions and I am not responsible if your device is damaged, If my article violates the forum's terms and conditions, please admins accept my apologies, I want only to help people.

This guide ONLY to repair the ORIGINAL Samsung Note10+ N975F using the ORIGINAL IMEI NUMBERS, the tool not support changing the IMEI.

Your Note10+ must/will be rooted and you will lose your warranty and some Samsung services.


This is how I fixed my Note10+:
1- I found a repair tool which support N975F and will not need a box, the tool called ChimeraTool.
2- Bootloader must be unlocked which in my case was already because I lost the EFS folder while rooting the device.
3- Enable USB debugging from the developers options, from your PC open ChimeraTool and connect your Note10+.
4- Repair your IMEI from ChimeraTool ----> Repair -----> Repair and type your IMEI numbers. (here you will see your IMEI numbers in "About Phone" but you can't make calls, you need to install some certificates)
5- Root your Note10+ using this guide by @dr.ketan https://forum.xda-developers.com/gal...te-10-t3960031
6- Go back to ChimeraTool ----> Repair -----> Patch certificates.

Enjoy

Please Note:
1- Read the root guide carefully, specially:
(Powering up normally) → (System with NO Magisk)
(OEM Recovery Key Combo) → (Splash screen) → (Release all buttons) → (System with Magisk)
(OEM Recovery Key Combo) → (Splash screen) → (Keep pressing volume up) → (Actual recovery)

2- The fix take from me 2 tries, first try and after I finished fixing the problem and started to install my apps to start using my Note10+, I restart the phone but it could't boot the system, but the second try, now I used the phone for 3 days and everything gos smooth like any normal Note10+

3- If you do a hard reset or install a new firmware using Odin you will lose the IMEI again lose the certificates so you will not able to make calls, but you will able to see IMEI numbers in the "About Phone"

3- You can do a factory reset without losing the IMEI or certificates but If you do a factory reset from settings, you must click volume up + power buttons as soon as the phone restarted to finish the factory reset. (it looks like the system can't enter the recovery automatically because of the root).

4- If you flash a rom using Odin you will lose the certificates and you will not able to make calls but you will able to see the IMEI numbers in "About Phone", you will need to repatch certificates using ChimeraTool.

Best Regards





Update 30.11.2019:

The phone still working perfectly, I unrooted my Note10+ by uninstalled Magisk from Magisk manager, Norton antivirus telling me No risks found in my system, the phone is not rooted and no untrusted certificates ...etc, in Software update the phone telling me I have the latest version (In similar case the Note 9 was telling me my phone has a custom ROM and can't get updates) so I hope I will get official update in the future for my Note 10+.

you need a subscription for chimera and then some of the activities require purchasing also.. i got me a free year subscription but that was a hookup lol.. prior to that tho i paid for it.. just the flashing feature is worth it for someone like me whos constantly flashing.. it allows to select a whole firmware file and can pick which partitionswithin the firmware u want to flasj.. i.e u dont need to b constantly ectracting and packing stuff u want to flash

I could't understand you 100%, for me the fix cost me only 11.90€ (the 3 days start license), I never needed any other purchasing, I used Odin to flash the ROM and Magisk-Patch.tar, not need any other tools or purchasing.

Best Regards
