What could disrupt the WebUSB Install in Vanadium?

X43 Vol Down > Select Recovery > Power + Vol Up > Select 'Enter Fastboot mode'

You're trying to flash from Fastbootd, not Fastboot. Try shutting down your phone then do the same power + volume down key combination and stop there. The menu that pops up there is Fastboot.

You again -.- it's the only scenario in which the device shows up. But as explained, it does a reboot to first screen (vol down) and connection lost .

X43

missing-root troubleshooting. Graphene installer needs unlocked bootloader, right? So I tried different things, but conclusion is: phone doesn't show up normally (need to go over recovery (device can be selected, installer starts > back to first screen (vol down) where it never ever got detected, so connection lost, installation stops

X43

de0u thanks, no of course it's not the cable. This things never work for troubleshooting, or I never fail to read guide/ use original cable anyways, etc

Carlos-Anso

X43 of course it's not the cable.

This could be a dangerous assumption to make. Generally a new cable as supplied in a sealed box with the device will work fine. It is possible that it could have a manufacturing defect. Also if its not brand new it could be damaged.

Cables supplied with phones from 3rd party phone refurbishers tend to be low quality.

Besides the cable, as people have already said you need to be in fastboot not fastbootd to flash GrapheneOS

X43

Carlos-Anso yes, and I'm sure you didn't read why I'm there.. In fastbootd (entered through recovery) device get's recognized, in fastboot (first screen) not. So, please explain how a damaged cable can be used for this 100% reproducible error (yes, not even once detected there, not even once not detected on the wrong screen).

Can someone with knowledge please shime in and direct us in right direction, please? Setup seems fine, but when is a stock device behaving like this? Beeing undetectable in fastboot, while proofing it generally has no problem connecting + the installer works

How would one produce this on purpose?

Carlos-Anso

X43 i did read why you are here.
Despite what you appear to believe a lot of people trying to help you out here have a lot of knowledge.

USB problems are the most common cause of flash failure. Devices can even get half way through flashing and then fail because of a low quality cable.

In your position I would try a different cable and even flashing from another different android phone. It could be the usb port on a phone has problems.

You can not flash from fastbootd. The fact you cant see the phone when in fastboot points to your problem. Its very likely to be usb related.

Hi everyone! 1 year later i experieced the same usb issue and i can confirm 100% that is a port/cable issue.
Cable was good but the port i used was the one on the hub station (actually a good one Cladigit TS5 plus).
Even if i successfully flashed graphene with that port i somehow was unlable to flash stock android on that same port (with the same cable). THe proble i had was the one u were talking about :

X43 In fastbootd (entered through recovery) device get's recognized, in fastboot (first screen) not.

i connected the cable direclty into the computer and the issue was gone .

X43

Carlos-Anso no. It's not hardware related. Can't I use ADB on android and sideload graphe somehow?

X43 Since we have narrowed the problem down to target device, and that thread got closed as dublicate, I'll give up, you won.

Several questions/suggestions raised earlier have not yet been addressed:

de0u Can you confirm that your questions are about the web installer on the GrapheneOS web site?

de0u Has this particular cable previously been used for a successful flashing of GrapheneOS?

Which version of Vanadium do you have, running on which version of GrapheneOS?

Carlos-Anso In your position I would try a different cable and even flashing from another different android phone. It could be the usb port on a phone has problems.

Carlos-Anso

X43
There is no other way.
You need to connect in fastboot.
Ive told you what to try.

X43

Carlos-Anso so I'm the first one ever who has a device which outright refuses to do that?

Since we have narrowed the problem down to target device, and that thread got closed as dublicate, I'll give up, you won.

Since the option to use WebUSB API was added (web installation method), the guide specifically mentions in the prerequisites:

You should avoid using a USB hub such as the front panel on a desktop computer case. Connect directly to a rear port on a desktop or the ports on a laptop. Many widely distributed USB cables and hubs are broken and are the most common source of issues for installing GrapheneOS.

@X43 with regards to your initial question:
