Thanks a lot @piero for taking the time to maintain this in such a dedicated manner.
I recalled what I did and I think now I better understand the ramifications:
My guess now is that the installation of the 15 Seconds ADB Installer did something similar to the above mentioned Adding adb path to the environment variables-part for unpacked SDK.
And I suspect that’s why I’m able to shift + right-click into any folder (that contains the downloaded files for flashing, for example) and select from the menu to launch a powershell window in that folder that accepts adb and fastboot commands.
(which in turn makes the ‘put the necessary files into the adb-installation-folder’ part redundant… though perhaps not for those who just unpacked the SDK but skipped the add adb path to environment variables part).
I think that is a good tutorial for installing /e/OS on a compatible device. My problem is simplier because I have a Murena One. There is a menu to restore to original configuration. But are they some tips to know ?
thanks
Hi Pierro,
I have been trying to install eos on my Old LG G5, but not working.
Well, I am coming from DivestOS, since they stopped the project.
I install the eos recovery with fastboot flash recovery recoveryxxxxx.img", but not I am not able to reboot to recovery with keys in my case (volume down + power on…). I tried then to sideload eos zip, but its not working. getting the error 21 at 47% with signature verification failed error.
DO you know how to bypass all this?
Thanks alot
because you come from another android distribution,
this is a normal behevior that the process hang at 47%, for a loonng time, “patching system inconditionnaly”, just wait… there is not more error message, just wait…
No actually, it does not hang on 47% for long time. Neither it asks yes install anyway. It just aborts the installation throwing this error. Well I guess the error is also coming from the recovery. because I am not able to reboot into eos recovery mode although I factory reset the phone and wiped the cache…
I used the command “fastboot flash recovery eos-recoveryxxxx.img” it works fine, but inorder to reboot into recovery with powerand volume buttons, it just does not reboot into eos recovery!
At least I tried several times before I give up!
my device is LG G5.
I read that the first time it must be with buttons and not through command line because otherwise it just boots into the installed OS!
On your device, go into Settings → About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:
adb reboot bootloader
You should now be in fastboot mode.
Download the correct image file and copy the file into the same folder as your platform-tools. Rename the image to twrp.img and type:
fastboot flash recovery twrp.img
fastboot reboot
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don’t follow this step, you will have to repeat the install.
Well last thought I got is:
LineageOS stopped supporting my phone LG G5 h850, and since as far as I know that eos is a sort of fork of LineageOS, so I am wondering if this could be the issue?
Just wonrdering!
I have retried to first type the command:
$ fastboot reboot recovery
juste right away doing the keys combo to boot into recovery but not able to boot into eos recovery!
hmm, no this cmd does not work for me:
I get: < waiting for any device >
I actually do ($ adb reboot bootloader then $ fastboot reboot recovery) and this works, but again not in the eos recovery
Before proceeding ensure you have downloaded the custom recovery from the link given in the Download section above
Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
With the device powered off
hold Volume Up + Power.
Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
5.Tip:* If you see no permissions fastboot while on Linux or macOS, try running fastboot as root
6.Tip:* Some devices have buggy USB support while in bootloader mode. If fastboot hangs with no output when using commands such as fastboot getvar … , fastboot boot …, fastboot flash … try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub
Flash a recovery image onto your device by typing
fastboot flash recovery recoveryfilename.img
Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section
Now reboot into recovery to verify the installation:
With the device powered off
hold Volume Down + Power until the LG logo appears, then release Power for a second and hold it again until the recovery comes up.
