Samsung A20s root 只欠一步 請求高人幫個忙

麻煩各位大大 請幫小弟一個忙 以下這段是我Root A20s(SM-2070)的說明教學
但我的英文能力是與無能為力劃上等號 我只好用GOOGLE翻譯去看 以下的步驟是我已經從Odin AP刷入成功了 唯獨只欠最後幾步

從步驟1“降低音量 + 电源”  按钮退出下载模式 再到2关闭屏幕后 是否要在開機前 就快速按下提高音量 + 电源按钮 直至到出现引导加载程序警告就按住音量调高按钮 (是看到了警告字眼才按住音量调高按钮定還是在未看到警告字眼就已經好要按了)手机将进入库存恢复模式。 完成3之後就Reboot 系统
但就一定要在系統重啓前 快速同时按  Volume Up + Power  按钮。当引导加载程序警告再次出现时，这次松开按钮。是這樣嗎 因為我做了多次也不成功

還有最後的那個結論 我完全不懂是甚麼意思 勞煩各位大大指點下我這一隻迷途羔羊 麻煩了各位

1: Once Odin is finished with installing Magisk, press and hold the Volume Down + Power button to exit download mode.
2: Once the screen is off, quickly press the Volume Up + Power buttons at the same time. A bootloader warning will show up. Keep pressing the volume up button. The phone will enter the stock recovery mode.
3: Using the volume buttons in recovery, highlight Wipe data/factory reset and press the power button to confirm.
4: Now highlight and select the Reboot system now and quickly press the Volume Up + Power buttons at the same time. When the bootloader warning shows up again, release the buttons this time around.
The process above will enable root permission on Samsung Galaxy A20s SM-A2070 and will also install Magisk Manager. This is the app that you have to use to control root functions and to download and install different modules.
Conclusion:
All you need to remember is the bootup procedure, and what you need to press if you want to boot in recovery or boot the system with Magisk installed.
1. Powering up normally → System with no Magisk
2. Power + Volume Up → Bootloader warning → Release all buttons →System with Magisk
3. Power + Volume Up → Bootloader warning → Keep holding volume up → Actual recovery

一會兒再root 先謝過師兄幫忙 唔該了^.^

咦 不是不是 這個我懂 我失敗原因是因為我過不了最後一關
即係我貼了上來的那一段 因為部機root完後 是會出現點瑕疵
不是我這一部才有 是這個型號所有都是這樣
我只是不明白我貼上來的這一段 我才會人敗
還有個結論 我也不明白

明白 唔該晒 一會再root多次^.^
