Axon7 assert failed: axon7.verify_trustzone("TZ.BF.4.0.1-00315") == 1

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.

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 :

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

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…

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?

remove these lines till ui_print save file and flash

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

Adeolu

@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 ?
