@nico let us know if you were able to install the /e/ ROM
I did it !
Installation successful without any problem thanks to the wiki.
Now time to discover /e/

Great!!! Once you have used it for a few days let us know your feedback on /e/ 
Hi,
After a few days of usage, I’m quite happy with /e/ and I don’t regret switching. Here is a first of annoying things I’ve noticed:
- I liked the “swipe fingerprint sensor to make status bar appear”. I haven’t found this feature currently on /e.
- moving app icon to the screen border is too sensitive : you get instantly to first or last screen.
- grouping apps in folder seems buggy : sometime, the app folder disappear.
- battery consumption seems higher than before (compared with OnePlus android). After one day of use (out of home, LTE network, …) battery goes down to 60%, while with OnePlus Android it was about 70%
Thanks for your work.

only drag between screens and since September 17… I was thinking about another launcher, Smart Launcher (ginlemon.flowerfree)
Are there also issue on grouping apps and battery depletion?
These two issues are not yet mentioned in Gitlab.
It would be great, if you could raise bugreports for then as described on https://gitlab.e.foundation/e/wiki/en/wikis/issues
@nico I am currently in the process of installing /e/ on my oneplus 5t, but not having the best time 
You had no problems?
Been following the instructions here: https://gitlab.e.foundation/e/wiki/en/wikis/device/dumpling/install
and everything is pretty much as described until it gets to using twrp. I downloaded and installed the latest version: twrp-3.2.3-1-dumpling.img
Some of the menues don’t seem to be the same, so that made me think that twrp was updated since the wiki got written. Still I can follow the general instructions up to the point where it is needed to push the /e/ install zip to the sd card, I get this error:
adb: error: failed to get feature set: no devices/emulators found
nevermind there is an “install form adb” option, so I tried that it asks me to use the adb sideload “filename” command, when I try that it starts transferring the file and finishes, but the install fails.
@supportpeeps am I doing something stupidly wrong, or should I use a different twrp version? not sure how to proceed
Hi,@Carlos.
In my experience with several phones it’s too much simply to copy the ROM you want to flash to the memory card (SD) instead of doing via sideload.
How to do it? Enable the transfer of files on the USB menu in main screen or FTP it (if you have an app for FTP server just like “File manager HD” which implement FTP transfer directly to your device’s SD media). Copy the ROM to your SD media.
After that you can install the new ROM following the steps in the link: Wipe and, after did it, go to Install chose install > select storage > SD card. On your SD card directory chose your ZIP and install it. Wipe the cache as suggested and reboot on system.
(Sorry for my English)

Hi @Erekoze,
Thanks for that advice, tried doing that and the files transfer nicely, when I try to install from internal storage it still ends on “installation failed” though.
I’ve realised that my oneplus seems to have been updated to the latest oxzygen os which is based on pie. Could that be the main issue? I might also try with a few different nightly builds, to see if that makes any difference
Thanks for the help man, much appreciated!
I don’t think so, @Carlos. The ROM’s didn’t “see” that. The obvious point is: It’s the ROM you downloaded correct? Did you checked the MD5 hash?
Im not gonna lie, I didnt really know what that was, but after I checked it now, it seems to be correct
Checked it on windows using "certutil -hashfile e-blabla.zip MD5
That the right way to do it?
EDIT
If it helps in any way, if I do the adb sideload it seems to go well until roughly 50%, then the cmd prompt changes to Total xfer 1.00x and the phone screen changes to installation failed
EDITEDIT:
Also get installation failed when I try to reinstall the latest firmware
I don’t use Wind**s, sorry. The only thing, for real, is that you’ll get better options if you copy the zip on the SD card, IMHO.
I checked and have a question: Do you have a ‘-hashfile’? I presume its a textfile. Am I wrong?
Hashfile? Do you mean from the command to query the md5 hash? it doesnt spit out a file, just the hash itself in cmd prompt, I compared it to the one provided in the install link and they matched.
The internal storage being “more likely to work” makes sense, but I end up with the same error. Even tho windows can be a potato, i think in this case its innocent
OK @Carlos. I never installed this exe, I don’t use Wind**s, so I don’t know how it works. Usually this kind of programs give the result on screen, as you said.
I’m out of options. 
I just checked how the command works on linux and doesn’t has the -hashfile option so I’m blind about it.
No worries, thanks though man, your help is really appreciated, lets see if one of the /e/ guys sees this, they might have another idea.

Hi
Can anyone help me for oneplus 5T device. I followed steps now it has \e\ ROM but its not rooted. Can I know how to root device or I did something wrong ?
Thanks
/e/OS is a non rooted system, if some of your apps need root permission, you can obtain it using « magisk », (flash the zip with TWRP)
