Upgrade Samsung A52 /e S to /e T without step over stock rom

[msfox]

I have a Samsung A52 with latest version of Android 12. e-1.17-s-20231110351092-dev-a52q.zip
I know, I don’t update automaticly with the “Updater”. I must use the recovery und upgrade manuell with e-2.3-t-20240819427106-dev-a52q.zip
BUT, in the instruction is writen: "Before installing /e/OS on the Samsung Galaxy A52 4G a52q for the first time, install the latest stock OS version 13 build on the device ".
I don’t have a stock rom installed. I have /e/OS. Now I must really first install the stock ROM? That’s not nice, because I must reset the phone?
Or can I Upgrade directly without the step over the sock rom?

Hi @msfox welcome to the /e/ forum.

I am sorry to say that it will be necessary to revert to stock ROM, there is a support topic page here Revert Samsung Device to stock ROM on Windows PC.

This ROM, unusually for current /e/OS Android 13(T), contains an updater-script which includes in line 2

abort(“ERROR: This package requires Android 13 based firmware. Please upgrade firmware and retry!”

This issue was seen here Upgrade from android 12 to android 13 and Can't install e/OS on Samsung Galaxy A52 with adb

@aibd

welcome to the /e/ forum.

Thanks.
I don’t know, if I had installed Android 13 Stock, before I had flashing /e/OS with Android 12. That was in december 2023. In this time, the phone was uptodate with Stock Rom. How can I check, maybe the correct firmeware is installed?

When you installed /e/OS at Android 12, you would almost certainly have been required to have Android 12 stock.

Try Settings > About phone > Android version.

In this section you should find Vendor patch level and Baseband version. With a Samsung, very often an online search of Baseband version will reveal your (last stock derived) firmware.

Dirty upgrade to /e/OS-T look possible ! (for some devices)

The official documentation seems not accurate (inherited from previous versions), since the /e/OS-“T” build generation (like LineageOS 21) are expected to include the updated needed parts of the firmware. finally the sentence : “your device must be on latest android” (that leads in many case to lose /data by reinstalling full stock software ) now looks not mandatory, at minus on a device already running /e/OS “R” or “S” version. . @Leon If you reread attentively their post, none of them ha…

Upgrade from android 12 to android 13

i remember Manoj said that “new” android 13 based customOSes (lineage and its fork /e/) are expected to include firmware parts that needed to be updated/upgraded

I will get back to stock rom in order to install the last version of e/OS. It’s gonna take time to get everything back to as it is now (configuration, applications, etc…).
I saw that Android 14 is avaliable as stock ROM so I wouldn’t like to upgrade to Android 13 if e/OS switches to android 14 soon. Don’t want to do the job twice, once is already boring me.
Does anyone know if a new version of e/OS with Android 14 will be released soon ?

@Halwa

Does anyone know if a new version of e/OS with Android 14 will be released soon ?

It probably will happen within a few months. Meanwhile Lineage4micog is available a52q at Android 14, so you could perhaps use that till /e/Os is released.

[Halwa]

Thanks for your reply.
I don’t know Lineage4micog, how do we switch from it to e/OS ? We can directly install e/OS above it ?

[aibd]

Yes, should be ok. Make sure you have a backup strategy though, “just in case”.

/e/OS is forked from Lineage; Lineage4microg is another fork or variant.
