Hello,

I’m trying to flash /e/ on a Axon7 A2017G phone but I can’t get rid of this error :
assert failed: axon7.verify_trustzone("TZ.BF.4.0.1-00315") == 1
Same thing when trying to flash the official LineageOS 15.1
According to some thread on xda-developers I should “flash the right bootstack” but I don’t get exactly what it is.

I tired to install different versions of TWRP : the one recommended in /e/ documentation and the latest I could find on the official TWRP website with no success.
https://androidfilehost.com/?w=files&flid=274875
https://dl.twrp.me/ailsa_ii/

Any idea ?

Thank you !

@rhunault please can you check what can be done here.

#3

I could fix the issue with LineageOS (+ microG) but I still have the same error with /e/

btw I think it is more relevant to follow this topic on xda than the official /e/ / lineageos installation instruction :

#4

i can help you to fix that, but need to check updater script from the rom.zip… can you share with me?

#5

I used the latest /e/ : https://images.ecloud.global/nightly/axon7/
e-0.1-201901092493-nightly-axon7.zip

this TWRP : https://androidfilehost.com/?w=files&flid=274875

#6

and A2017x_LineageOS15.1_UniversalBootstack_v2_by_DrakenFX.zip and A2017G_OreoModem.zip files here : https:// androidfilehost. com/?w=files&flid=270519

(sorry new users can’t post more than 2 links)

hm my posts are “hidden by community flag”
I wonder why… too many links ?
they are quite clean though, taken from the official lineageOS thread on xda…

#8

i need file… from rom zip…
updater script located at META-INF\com\google\android

#9

well I guess it was in one of my hidden messages : the rom e-0.1-201901092493-nightly-axon7.zip
download from the link I found in the official /e/ documentation I can’t post here :confused:

#10

ok, easy way can you open that updater script if you have zip… and paste the first 6-7 lines from the file?

ZTE - Axon 7 - install /e/ gives Error 7

I have un-hidden the post. It got automatically blocked for too many links to the same domain. You should be able to view them now.

#15

thanks !

I successfully flashed, but instead of booting the system, the phone turns itself off.

#16

btw since I’m here and before I bother further I have another question :
are there any videos around showing /e/ interface and applications ? (/e/ is a terrible name to search anything)

#17

There are some video’s users have uploaded on youtube and other similar sites.
You can get an idea about the interface and the project from the website as well https://e.foundation/
Some articles on the project are posted here https://e.foundation/e-first-beta-is-here/
https://hackernoon.com/leaving-apple-google-a-global-eelo-development-status-1ee11bf80d06
On the name /e/ we agree on that and a proper TM has been registered but due to legal requirements there is wait period before we can publicly declaring it.
Even our page on wikipedia https://en.wikipedia.org/wiki//e/_(operating_system) calls us /e/ …for now :smile:

This video is from November. There have been several changes and improvements since then.

Hi Markus,
Thanks for the feedback.

I’ll see if I can update my /e/ build and create a fresh video only if time allows…

Kind regards

@kro were you able to flash the /e/ ROM?

#21

nope. I always had the same error with /e/. I was able to install LineageOS though. So I installed LineageOs + MicroG but since it is my daily device I wont try to format it and install /e/ again.

I use my own Nextcloud server anyway, and funny thing, almost every apps I use have been selected for /e/ (lineage, microg, davdroid, ask keyboard). I wonder if there is a list of this apps somewhere (I can’t find info about the email client for instance, is it k9 ?). Are they available as apk on a repository or something ?
