What's Working
- ADB
- File Decryption* (A12 and A13)
- MTP (works when you successfully flash and boot from retrofit rom)
- USB OTG
- Vibration
Installation guide (Read carefully)
Attention: This version support F2FS userdata only.
This TWRP ONLY support Retrofit version ROM (Modified partition)
IF you are from non-retrofit version (e.g from EvoX 6.6 to EvoX 7.0),
- Flash TWRP-3.6.2_12.0-CEPHEUS-RETROFIT-UNOFFICIAL.img and boot into recovery
- Sideload retrofit ROMs ( Advanced > ADB sideload ) or Flash using USB OTG
- Flash Magisk (Optional)
- Change Cache to F2FS (Optional)
- Format Data (Wipe > Format Data) (Mandatory, else will fail to boot / back to rec)
- Reboot & Enjoy.
Tips 1: If after installing the ROMs and reboot kick back to recovery, format data again.
Tips 2: User who use EvoX recovery to flash rom does not need to follow the guide above.
Tips 3: User using retrofit ROM want to change to the other ROM doesn't need fastboot flash super_dummy method anymore
Tips 4: DO NOT BACKUP and RESTORE using TWRP, else decryption will fail and your data is gone. You have been warned.
*The guide has been revised and rearranged for better understanding since not many users can follow it, my bad.

中文翻译:教程
在酷安和Telegram里看到有些用户不知道这款rec只适合RETROFIT的ROM,在此我声明:
请注意,此TWRP Rec只适合Retrofit版本的ROM (已魔改分区的版本)
想装EvoX Retrofit版本的 (如果已使用官方EvoX rec的请忽略),需要跟随以下步骤:
- 线刷 TWRP-3.6.2_12.0-CEPHEUS-RETROFIT-UNOFFICIAL.img,重启进入rec
- 把语言设置成华语(Settings > 点击地球形状的logo > 选择 Chinese > 点击右下角 Set Language )
- 使用 ADB Sideload 方式刷你想用的ROM (高级>ADB Sideload) 或利用USB-OTG 刷你想用的ROM
- 刷面具获取root(非必要/ 用户自行选择)
- 更改 Cache 格式 为 F2FS (非必要/ 用户自行选择)
- 格式化 Data 分区(清除目录里)
- 重启,完成
注1:如果重启系统后,被强制进入rec的 请再格式化 data (确保data的格式是F2FS)
注2:如果你已经通过官方rec刷EvoX Retrofit版本的ROM,能直接使用。
注3:如果你已经用retrofit的ROM,想换去其他版本的retrofit,无需再使用fastboot wipe-super的步骤*。
注4:请勿使用备份和恢复功能,否则资料丢失。
PixelOS 和 LineageOS 需要刷 flash dummy的包来取代用fastbootd。
刷rom之前先adb sideload或 通过USB-OTG刷 flash dummy 的包就可以了。
