Hello,
I want to install the Android 14 version of e/OS on my A52 4G and whatever versions are available in the download directory https://images.ecloud.global/dev/a52q/, none of them provide the vbmeta.img file in the zip file. Any advice on how to proceed?
Thanks in advance.

Horrible, this constant carelessn/e/ss.
Try these: lineage-21.0-20250101-microG-a52q-vbmeta.img
/e/OS-U (A14) is based on LineageOS 21.1 (A14)
Thanks for your quick reply, I’ll try with the one you mentionned
Hi,
I have a problem installing e-2.8-a14-20250220470208-community-a52q on my Samsung A52 4G.
First, there was no vbmeta.img in the package, so as adviced by Xxpsilon (thanks to him) I downloaded and used the one here : lineage-21.0-20250101-microG-a52q-vbmeta.img as /e/OS-U (A14) is based on LineageOS 21.1 (A14).
So, I flashed the latest official Samsung ROM and flashed Vbmeta.tar with Odin.
I tried to flash the recovery recovery-e-2.8-a14-20250220470208-community-a52q.img with Odin too but it failed. Odin crashed each time. Then I decided to flash the latest TWRP recovery for the A52 4G with Odin and everything went fine.
Last step, flashing e-2.8 version.
I tried through the installation through « Apply update from SD card » or through adb with the adb sideload command and each time, it doesn’t work.
In both cases, TWRP messages are :
Supported API : 3
Finding update package…
Verifying update package…
Update package verification took 28.5 s (result 1).
Install completed with status 2.
Installation aborted.
I went in the logs and found messages like this :
I Failed to verify against RSA key 0
E failed to verify whole file signature
E Signature verification failed
E Error 21
I checked the sha256 of the downloaded e-2.8-a14-20250220470208-community-a52q.zip and it’s correct.
Does anyone had the same issue ? Any advice to complete the installation ?
In TWRP, you can disable ZIP signature verification
Thanks, It seems I need to go in Settings to do so but I don’t have the User interface. After the installation here is what I got when I reboot into recovery
How do I do to disable the zip signature ?
@Halwa maybe the /e/OS-U biuid is faulty! I would first try to install the official and stable CustomROM LineageOS 21.0-for-microG. That would be a good starting point to then try to install /e/OS.
This is not TWRP, but stock Samsung recovery
That’s an option indeed but I assume I’m not the only one willing to install e/OS-U build. So if it was really faulty, It would probably be mentionned in the forum.
OK thanks, i’ll try the installation again.
Cool, it worked with TWRP skipping the signature.
Thank you Piero & Xxpsilon for your answers.
