On the install page I am looking for a precaution to be able to return to the factory Android. Is that done by making a TWRP backup before the install?
I see a reference to TWRP, but on the TWRP-site I don’t see the GS290. Any suggestion where to find it?

Thanks for pointing out the error in the GS290 documentation. There is no TWRP official image for the GS290 that I am aware of. Will remove the reference from the documentation.

After installing /e/, is there a way to restore the original factory Android on the GS290 ?
Would this normally be done by way of a TWRP-backup?

Hello tried to flash according to your instructions. Unfortunately it gets stuck in the start screen after reboot. What’s my mistake? Can I get back to Ubuntu from your rom?

Hi, I just installed /e/ on my new GS290 and I think you forgot to unlock the bootloader in “Developer Options” Even if you are in developer mode it will still be locked by default

Yes, I saw the same. I did this explicit unlock and the process went smooth.

Dear Manoj,
I’ve installed /e/ on my mom’GS290 yesterday : it works !! 
…but it was a little bit tricky because of some missing points.
-
In addition of “enable-usb-debugging”, I had to enable the OEM unlocking option in the Developpers options. As @sugit and @keesson01 mentionned.
-
As a Linux based host for the flashing, I had to create a “plugdev” group and install the
android-sdk-platform-tools-commonpackage (as it is mentioned in the android doc). -
It might be unclear - if not explicitly written - that the use of fastboot command can’t be available (
fastboot devicesfor instance) before adb command is launched (adb reboot bootloader).
Hope it could help !
And… thanx a lot to you and all the /e/team for that superbe work !!! My Mom is happy again … 
A /e/ user happy

"Orange State
Your device has been unlocked and can´t be trusted
Your device will boot in 5 seconds"
on/off and Volume up/down no reaction … in adb no Device is listed … how i can fix it ? or i bricked that funny thin now ?

Finished. Total time: 0.338sOk, installation instructions from the documentation works fine after the flashing “gs290_10.zip” firmware using SP Flash Tool. It was really hard work. But it’s all good now.
Looks like this problem comes from latest official OTA updates. Please update the docs!
Pl can you share what steps need to be updated in the documentation.
@Manoj There should be added a section 2.1. OEM Unlock, unless it’s a better choice to add it to https://doc.e.foundation/pages/enable-usb-debugging. Although the OEM Unlock is different for some devices (i.e. FP3 where you need a code).
This has been brought up here: GS290 not supported in easy-installer?
We can add the extra step to unlock oem in the https://doc.e.foundation/pages/enable-usb-debugging document as that is where the user sees the option.
Hi , I cannot find how to manually boot in fastboot mode ? this should be in the Doc.
If you meant how to reboot into fastboot mode it is available in the documentation Step 3 in the Before flashing
adb reboot bootloader
Thx , i read that but the guy I’m trying to help on fr telegram channel is stuck in bootloop , he needs key combination
