As a Customer this will apply
Getting help on the forum is all very well but it may get messy so Customer support may provide the best answer.
Meanwhile … there are a few technical issues you will face.
- Most likely a locked bootloader
- A stable build, now designated “official”. This should have received OTA Android version upgrade … but it was clearly missed.
It is a little unclear, but it has been suggested that when an OTA upgrade is marked “completed” it is no longer available OTA.
You probably can Upgrade without wipe data as there is available a copy of the current OTA update file:
- https://ota.ecloud.global/official/FP4/e-2.5-t-20241108446629-official-FP4.zip
- md5sum: 9d3ab4303808353ccddbf6f7d4424d1b
This is not to be used as the regular install page.
I posted this reply Why no updates in over a year? FP4 - #8 by aibd on a similar thread. Please read the whole thread before proceeding.
Always be sure to have a good backup of essentials before any work like this.
