Cara Downgrade ASUS Zenfone 2 Laser 5 ZE500KL dari Marshmallow ke Lollipop

Cara Downgrade ASUS Zenfone 2 Laser 5 ZE500KL dari Marshmallow ke Lollipop



 Namanya juga baru, pasti ada beberapa bug / butuh penyesuaian dengan yang lama, Seperti yang pernah disampaikan oleh Pihak pengembang, beberapa kelebihan OS marshmallow pada dasarnya sudah mendukung fitur2:

- Mendukung pemindai sidik jari.
- Android Pay (NFC).
- Irit baterai.
- Fast Charging.
- App Permison
- Auto Backup

Namun setelah beberapa hari saat mencoba fitur unggulan tersebut belum dirasa maksimal,seperti :
- Tidak mendukung instalasi ke memory external (APP2SD), jadi sepenuhnya mengandalkan memory internal 16GB yang sudah terpakai sistem 6GB, jadi 10Gb saja optimal untuk App
- Baterai lebih boros dari Lollipop (sebagai perbandingan biasanya saya memakai wifi untuk mengkases internet, biasanya biasa seharian, namun pada saat memakai OS 6.0 lebih cepat habis dari pada OS 5.0.2)
- App permision yang menghambat akses dari suatu app untuk membaca / menyimpan data,foto dan akses ke memory penyimpanan.

Dengan pertimbangan tersebut, saya memutuskan untuk mendowngrade kembali ke lolipop, berikut langkah yang telah saya coba, Cara downgrade ASUS zenfone 2 Laser Z500KL dari Marshmallow ke Lollipop :
- Backup dulu semua data dari internal ke external / ke cloud (Dropbox/ ASUS Webstorage/Drive Google)
- Download Firmware Lollipop ASUS ZE500KL : ASUS Zenfone 2 Laser - Lolipop Firmware (12.8.5.222) | 1,33 GB | 12 mei 2016 |
- Kemudian ubah nama firmware dari L UL-ASUS_Z00E-WW-12.8.5.222-user.zip ke versi M UL-ASUS_Z00E-WW-13.10.7.2-user.zip
- File yang sudah diganti nama tadi di salin ke internal memory, lalu cabut kabel data, kemudian muncul di notification bar update versi baru( baterai harus diatas 15%) lalu kilk OK
- Sistem akan merestar dan memulai update (downgrade)
- Setelah selesai sistem akan otomatis merestar dan masuk ke sistem
- Os akan eror karena dan melalukan restar berulang (karena proses bukan mengupgrade, melainkan mendowngrade)
- Cara mengatasi erornya dengan mehapus data (wipe), caranya sebagai berikut :
   - masuk ke mode recovery Mode : matikan HP anda, tekan tombol volume down (-), lalu diiringi


dengan tombol power [ (-) plus power ] sampai bergetar dan muncul logo asus, lalu lepaskan
   - lalu muncul Android system RECOVERY, pilih dengan tombol volume wipe data/factory reset, lalu ok dengan tombol power, pilih lagi dengan tombol volume Yes -- delete all user data, ok dengan tombol power volume, setelah selesaipilih reboot system now


- Hp akan restar dan seperti baru lagi, semua data seperti saat baru buka segel
Sekian cara downgrade ASUS zenfone 2 Laser 4G dari saya yang masih tidak sejalan dengan Marshmallow.
