請問我找到了LENOVO A10-70L 可以成功升級到Android 6 的ROW ,自行升級會有風險嗎?

我的 LENOVO A10-70L Android: 5.0.1 平板要系統更新一直無法更新
卡在無法升級到 A10-70L_S000119_161009_ROW

在LENOVA 論壇找到了資料
原來已經有很多使用者反映這問題
System Update is trying to download A10-70L_S000118_160504_ROW_TO_A10-70L_S000119_161009_ROW
很多人都卡在無法升級到 A10-70L_S000119_161009_ROW
應該是原廠相容的問題待解決!!

但是論壇裡也有人提到解決方法

已經有更新的ROW出來了
A10-70L_S000214_170606_ROW for the Lenovo Tab 2 A10-70L

他們提到可以直接從A10-70L_S000118_160504_ROW 跳到 A10-70L_S000214_170606_ROW
the update to Android 6 worked perfectly
可以成功升級到Android 6

因小弟沒有自行升級ROW安裝的經驗
請問如果照論壇裡的說明按步驟升級
或是告訴我正確清楚自行升級方式(中文)

會有風險嗎?
如果無法成功是否有什麼方法回復到以前版本..
感謝回答!!!
