# Flash LineageOS 18 to my Xperia Z3 -- Round 2

[TOC]

So... here is the reason why I need a "Round 2" for flashing LineageOS 18 again to my Xperia Z3, because somehow it soft-bricked and I just left it alone for few months.

Since my knowledge has grown more than before, I noticed that I actually don't need some tools that I had used in the past for flashing custom ROM this time, it is kind of surplus I just find out...

Anyway, here is my Walkthrough... again.

## Ref

[Flash LineageOS 18 to my Xperia Z3](/@cimeesia/HJmGUCJyc)

## All I need

- [Xperia Z3 driver](https://developer.sony.com/file/download/xperia-z3-driver)
- Official driver.
- [XperiFirm](https://forum.xda-developers.com/t/tool-xperifirm-xperia-firmware-downloader-v5-6-5.2834142/)
- Only needed for the 1st time. Though this is not necessory tool this time, but it is still an important tool.
- [Android Debug Bridge](https://developer.android.com/studio/command-line/adb)
- For many things, both sideload and fastboot.
- [LineageOS 18.1 (Nightly) and Recovery for Xperia Z3](https://wiki.lineageos.org/devices/z3/)
- AOSP Version: 11
- [Magisk](https://github.com/topjohnwu/Magisk)
- Version: 27

### Those I don't need this time

- ~~[MindTheGapps](https://wiki.lineageos.org/gapps)~~
- I don't need Google's product nowadays.
- ~~[Flashtool](http://www.flashtool.net/index.php)~~
- Surplus thing.

## Key Combinations

[Official Guide](https://developer.sony.com/open-source/aosp-on-xperia-open-devices/get-started/flash-tool/useful-key-combinations/)

- Recovery Mode
- > the device must be turned off and you must hold the key Volume down while you press the Power key.
- Fastboot
- > make sure your phone is turned off and press and hold the Fastboot key Volume up* when you connect your phone to the computer.

## ~~Walkthrough~~ Troubleshooting

Basically, all the progresses are the same as the guide on LineageOS's Wiki.

I'm only going to note something I learnt this time.

### Troubleshooting 1: Device Driver

Last time, I installed the driver with a very weird method somehow... This time, I found [this guide](https://xperiausbdriver.com/install-xperia-drivers-manually) that is teaching people how to install Xperia's driver, NORMALLY.

The only different part with the article is, I right-click at my phone, instead of right-click at computer.

### Troubleshooting 2: Removing GApps

In few years ago, I was a kind of people who cannot live without Google's product. But now I don't need it. Actually, I'm trying to avoid it, intentionally, because I trust Google less and less nowadays.

When I finished my flashing LineageOS into my Xperia Z3, booted it into system, I found out that the GApps I had installed long time ago are still exist in the system. So I searched the removing method a bit, and found [this guide](https://www.reddit.com/r/LineageOS/comments/xl8jve/how_to_remove_mindthegapps/).
