以下是刷機細節分享，按照論壇的方式刷機，會有驚嘆號畫面，應該是被ROOT過的標誌，或許之後再想辦法把ROOT權限還原，也請網友知道怎樣讓開機不會有驚嘆號的還原ROOT權限的方法告知，謝謝。

INSTALLATION FROM STOCK
Follow these steps if you are coming from stock. You will need access to a PC.
1. Prepare Odin, Samsung USB Drivers, PhilZ CWM Odin Flashable, and your phone with a stable USB connection.
要刷ODIN之前，要將NOTE重開機，成為DOWNLOAD模式才能刷，(進入DOWNLOAD模式：電源鍵+HOME+音量下--然後按音量上-進入DOWNLOAD模式)
2. Install the Samsung USB Drivers and fire up Odin.
3. Select AP and choose the PhilZ CWM Odin Flashable package.
4. Proceed to flash. Once done, reboot your device into recovery.
重開機進入RECOVERY模式，(進入RECOVERY模式：電源鍵+HOME+音量上[需要按久一點才會進入，畫面會有不同的兩種開機畫面跳動]-進入RECOVERY模式)
5. You should be in CWM recovery now. Flash this zip to get TWRP IsoRec: 20210209-boot_n7000-twrp_i9100_3311.zip
6. Reboot recovery. You should now enter TWRP IsoRec recovery. Proceed to the installation steps below, except for step 2.
INSTALLATION
All my builds are emulated storage capable. Repartition is required to install my builds.
And also, please backup EFS partition and store in a dry, safe place.
The below instructions assumes that your device has TWRP IsoRec installed, and all your data will be destroyed in the process.
先跑步驟2 和 步驟3，然後再步驟4，也就是刷步驟1，接著再步驟5，繼續下去
1. Choose your desired emulated storage partitioning configuration:
2. Reboot into recovery. Flash emulated storage capable TWRP IsoRec (flash as Image to Recovery): i9100-LOS-16.0-Emulated-Storage-TWRP-3.3.1-1.img
3. Reboot recovery. Flash i9100-to-n7000 TWRP conversion: lanchon-twrp-patcher-20160417-n7000.zip
4. Reboot recovery. Flash the repartition script that you have chosen in Step 1.
在TWRP之下，先選擇已經下載到記憶卡裡面的repit檔，接著再進去系統根目錄裡面(不是選擇記憶卡或是原來的安裝檔喔......)，進去/tmp，找到裡面的repit檔刷下去，才能完整地把磁區分割完成。這個步驟很重要，否則會出現ERROR 1，之後刷ROM也會出現 ERROR 7 ，只要這個步驟成功，接下來就沒有問題了。
5. Reboot recovery. Wipe /cache, /system, Non-emulated Storage. Then, run Format Data.
6. Proceed to flash my builds.
7. Flash ARM nano GAPPS and SU if desired, or boot_magisk.img if you need Magisk support.
這邊記得選擇ARM 的(不是ARM 64 是 ARM)，然後版本是9.0，再來是 NANO版，如果是STOCK版本會顯示ERROR 70，空間不足刷不進去
8. Prepare a coffee or tea and sit back on your couch. Click to reboot system, BUT DO NOT SWIPE TO INSTALL TWRP APP or you will end up in a bootloop!
重開機時，千萬別安裝TWRP APP，否則會一直重開機，請選擇不要安裝TWRP APP的選項，點下去就會重新開機到手機桌面了。
9. Remember to install Magisk Manager if you need Magisk support.
不過一開始跑起來狂LAG，之後跑完會比較正常一點，GOOGLE PLAY也可以正常下載東西，從ANDROID 4.1直升9.0，感覺不錯，只是跑程式真的很慢，享受刷機碰壁的過程，也算是一種殺時間的惡趣味吧......希望有網友可以分享如何讓開機畫面不出現驚嘆號，也就是還原ROOT的過程。
