Installing /e/ pie on Sony Xperia XA2

[JJR]

Try looking at this thread. I doubt Android Pie is still usable, but I still have an XA2 running the latest version of /e/ for it:

Upgrading Xperia XA2 to S, on top of R, given no stock Android R exists for XA2

Well, it’s that time again - now that the R builds have stopped updating for my XA2 (latest is 1.81; no 1.9 that I can see), it’s time to do the fingers-crossed-upgrade process again, this time to go to S. The docco, as usual, is a bit ambiguous. It suggests flashing to stock Android S before doing the /e/OS install via adb sideload. But there is no stock S for the XA2 - it stopped at R/11 (per this info). I am assuming, therefore, that it is fine to just go ahead and do the sideload directly …

Thanks JJR?

I’m french and my english is bad.
Must I reset my phone to factory settings before installing /e/os ?
Or Can I flash it since Lineage 22?
Thanks

“factory-reset” te donnera simplement un lineage tout neuf, effaçant simplement la partition /data
tu penses peut-etre à “restore stock Sony OS and firmware”

depuis android 13, pour la plupart des appareils, les parties importantes du firmware sont incluses avec les builds de Lineage et de /e/, je suis en train de décompacter la dernière version de /e/ pour vérifier si c’est le cas pour le Sony XA2 (pioneer ?)

le fichier fourni par /e/ comme celui de Lineage ne contiennent pas d’images de partition relatives au firmware,

1. te souviens-tu sur quelle version d’android était basé le SonyOS avant que tu installes Lineage 22.2 ?
2. cet appareil reçoit-il encore des mises à niveau de la part de Sony ?

Bonjour et merci Pierro,
Je pense que j’ai eu mon Sony avec Android 8 ou 9. Aujourd’hui je suis en Lineage 22 (android 15).
Je n’ai que les mises à jour de Lineage. Je ne sais pas comment avoir les mises à jour de Sony.

[piero]

d’après cette page Sony Latest updates | Developer World (merci @JJR) on peut voir :

.

un des pré-requis pour installer un “custom Android OS” est d’avoir comme base la version du firmware la plus récente fournis par le fabriquant, (relativement à celle que tu souhaites installer)

@florent.wehrli

Je pense que j’ai eu mon Sony avec Android 8 ou 9

tu vas donc devoir installer la version basée sur android 11.

@florent.wehrli

Je ne sais pas comment avoir les mises à jour de Sony.

pour recevoir les mise à jour ou les mise à niveau Sony sur l’appareil, il faut le SonyOS installé sur l’appareil…
OU
installer une version récente fournie par Sony en utilisant un outil approprié.

ton PC peut-il faire tourner Windows ?

Flashing Stock Firmware on Sony Devices

If you are using a Windows PC, and you have not unlocked the boot-loader on your device, you can use Sony’s flash tool EMMA to flash the latest stock firmware on your device. Full documentation and download are available on the Sony Developer World website.

Flash tool | Developer World

If you are using a MacOS or Linux PC, or if you have already unlocked the boot-loader, then you will need to use Flashtool

• Downloads for Windows, Linux and MacOS available at http://www.flashtool.net/downloads.php
• Good instructions for use on xperiafirmware.com

Finding the stock firmware

Before you can flash it, you need to find the correct firmware to flash. The EMMA tool - if it works for you - will find and download the latest official Sony firmware for your device automatically.

Otherwise, if you are using a Windows or Linux PC, you can use the XperiFirm ~ Xperia Firmware Downloader to find and download the latest official Sony firmware for your device. (The program is written in .NET and ships as a Windows .exe file, so Linux users will need to install Mono).

If you need access to an older version of the firmware, if you are running a MacOS PC, or if Xperifirm does not find the firmware for your device, then you will need to find the firmware elsewhere on the internet. Places to look include

1. xperiafirmware.com has firmware for many devices, including the following devices with official or unofficial /e/OS builds

• Z3 (z3)
• Z3 Compact (z3c
• [Xperia XZ1 Compact (lilac)][https://xperiafirmware.com/sony-xperia-xz1-compact/]

2. https://xperiastockrom.com has the above, plus

• Xperia Z5 Compact(suzuran) - make sure you choose the correct version for your specific model number
  • E5803
  • E5823

3. XDA Forums - find the forums for your device and then the relevant sub-forums
4. AndroidFileHost - search for your specific model number e.g. https://androidfilehost.com/?w=search&s=D6603
