I followed the instructions for installing /e/OS for a Motorola edge 2024, using files unzipped from /e/OS Recovery.
The OEM Boot loader is unlocked. Android version 15. USB Debugging is enabled. Fast boot devices command, shows device ID.
The following error is displayed when fastboot flash boot boot.img is run:
(bootloader) Preflash validation failed FAILED (remote: ‘’) fastboot: error: Command failed.
When the error was returned I went no further. Assistance is appreciated.
Not many Dynamic partition devices have /e/OS installed via recovery and sideload as users may have to decide for which partitions to use fastbootd. It would be quite a good idea to compare the LineageOS install page Install LineageOS on avatrn | LineageOS Wiki.
Double check everything as the author did not expect you to have to use fastbootd implies your device is not in exactly the same state as his test device.
Warning: Before proceeding with the installation, log out of any accounts you may have set on the stock ROM. Also, remove any screen locks that have been set on the device.
Before following these instructions please ensure that the device is on the latest Android 15 firmware.
This is the model I have XT2405-1. I was able to boot to fastbootd. I ran fastboot devices. No response. I would like to mention I appreciate the help.
The only version I have found for Linux is 34.0.5-debian. As for the phone, not overly concerned as I have a working phone, I will switch phones after the Edge 2024 has e/OS. Currently when I run fastboot devices, the ID is displayed.
Caution: The default adb installation on OS like Ubuntu can be outdated and can cause errors. We would recommend that linux distribution users ensure they use the installation process given here
I have an INtel NUC I will setup, the last time I installed eOS, I used a Windows PC, I kept one, its the you never know scenario. Let me set that up. I will let you know the outcome. All my systems are Linux. For the same reason we need to get away from google. I thank you for helping.
That is where I downloaded the platform files from. That Linux version is 34.0.5-debian. Which is not the version that was recommended. I looked for a Linux version 37.0.0. Unable to find it.
I thank you kindly for the information and the direction, I downloaded, unzipped, version is 37.0. Phone is in fastboot Flash Mode. Fastboot devices shows ID, fastboot oem get_unlock_data shows Unlocked. Phone in Bootloader, when executing fastboot flash boot boot.img, response is
ending 'boot_a' (98304 KB) OKAY [ 2.085s]
Writing 'boot_a' (bootloader) Preflash validation failed
FAILED (remote: '')
fastboot: error: Command failed
In searching for solutions I found https://droidwin.com/preflash-validation-failed-fix/. This did not work. I appreciate all the help I am receiving, many thanks.
recommended is to extract the .ZIP, open a terminal from the newly created “platform-tools” folder
and simply add ./ at the beginning of all your adb or fastboot commands, it will use the binary included into the relative folder (the latest version you just downloaded) instead of the version installed on your system (that can be outdated)
The phone was working beautifully, until I had the idea that the boot-loader needed to be locked.
After reading a number of articles, at least the ones that I found, stated to run the command to lock the boot-loader. That was the mistake. after the reboot No valid operating system found. I read articles and watched videos on how to fix the issue. Non of them worked. What is needed is a motherboard replacement. Whether I replace it myself or send it to Motorola to repair, the cost is far more than purchasing a phone. I am waiting on the arrival. I have written procedures for in detail. This next go around, I will not be attempting to re-lock the boot-loader. There are articles I read on the XDA forum that stated not to re-lock the boot-loader and other articles stating that a specific procedure needs to be followed to re-lock the boot-loader. Once I have the phone running e/OS, until I understand the procedures, the boot-loader will remain unlocked.
It cost more to replace the motherboard than to buy another phone. In time, I will address the motherboard replacement, for now waiting on phone to arrive.
