dan is your last post just about the certificates issue the white screen problem as well. sorry to be a pain

Somewhere someone found out that the certificate issue was linked to the white screen issue

The certificate is valid enough that the app installs but when it opens and tvOS goes to actually verify it, it then sees that it's not valid and crashes

I had a similar issue with iOS when I was doing the initial testing before I even made an app to automate everything

It could also be a bug that you've found in Kodi...

But if you go into the crash logs for your Apple TV (through Xcode) I'm guessing you'll see one for kodi referencing libsmbclient

But it's difficult to help without knowing exactly what has been done beforehand... so the best I can do is troubleshoot...

I did everything you said here & I'm still getting a white screen after all of this.

I really dont know why I'm having issues with this because before I delete my Kodi off my ATV 4, everything was working fine..including installing it with no issues (I delete Kodi because I believe the "Mimic Skin" was messing up my Kodi when it just only show a grey wallpaper & no menus)

Ive just sorted this after five hours today.
its all to do with the certificates
download this and drag it into keychain
https://developer.apple.com/certificatio...WWDRCA.cer
double click on the iPhone developer certificate near the bottom and there should be a green tick at the top

its all to do with the certificates
download this and drag it into keychain
https://developer.apple.com/certificatio...WWDRCA.cer
double click on the iPhone developer certificate near the bottom and there should be a green tick at the top

im pretty sure I did this already when I went into Keychain & saw that my iphone developer certificate was not trusted. So I made sure I click that part to trust it so that the App Signer can use my certificate.

Maybe I'm wrong but i check once I get home from work.

This blog post explains perfectly how to fix the certificate problem...

• Open Keychain
  
• Locate Apple World Wide Developer Relation Certification Authority in the login and system tabs, and delete the certificate
  
• Download the updated certificate from Apple’s website
  

Although, you may also have revoked certificates if you reset them (Xcode doesn't automatically delete the revoked ones)

... and how can i fix the problem with the white screen if i open Kodi on my ATV 4?

... and how can i fix the problem with the white screen if i open Kodi on my ATV 4?

If you don't have the latest version of iOS App Signer (r17), download it...

First, make sure that Keychain is reporting that your developer certificate is valid or not

If it is, continue on (unless you've manually trusted them)

Otherwise, try the instructions right above your post

Is those don't work try the "nuke it from orbit" method to fix the developer certificates...

Then, open iOS App Signer and re-sign

Completely remove Kodi from your Apple TV and re-install using the newly signed ipa file

Do note that if you reset your developer certificate, Kodi will no longer launch on any previously installed device without re-signing and installing again

I have used the the newest version of iOS App Signer
The Problem with the developer certificate i fixed yesterday.
I have restored the ATV 4 completle

but no chance to open kodi afer installing it - only white screen :-(

I'm going to give this a try once I get home. Thanks again.

Okay, for anyone having issues still this should completely reset the developer certificates

Go into Xcode > preferences > accounts and remove your account from Xcode

Then go into keychain and then login and then certificates, delete anything that says iPhone Developer

Add your account back into Xcode it should complain about having to reset the certificates

Open finder and then go to the folder ~/Library/MobileDevice/Provisioning Profiles and delete everything inside there (Use command shift g for go to)

Then start follow the guide from step one since Xcode was completely reset

Hopefully this should sort things out

Beautiful white screen I had .. Just follow your instructions then downloaded https://developer.apple.com/certificatio...WWDRCA.cer
Goodbye white screen
Worked perfectly
DanTheMan, you're the man

[Shinobi_Wan]

So basically I finally fix the dreadful "White Screen" error that was driving me nuts for the past few days...

Pretty much in Keychain, you have to not only delete the WWDR Certificate in "login" & replace it with the new WWDR certificate that DanTheMan posted but you have to delete the WWDR certificate under "system" in Keychain as well.

Heres the link for anyone that still stuck. This should help get through this, just follow the instructions.

I just tried to launch Kodi on my iPad and I got the message:

"Kodi" Is No Longer Available

I thought I might need to Re-Sign the app and reinstall, so I tried to go to iOS App Signer, however, I get the error:

No codesigning certificates found

I've gone in to Xcode and downloaded my provisioning profile. But I can't seem to get a code signing certificate? Any ideas? I don't have any Fix Issue errors on the main Xcode screen.

Hello there everyone,

I'm new to this forum and having the White Screen Error evening after trying all of the above suggestion. How do I go about checking the error log in xcode for further troubleshooting?

[3HMB]

Update on my last post. I decided to get it a other try at home on my VM and this time it work. Just like DanTheMan and Shinobi Wan suggested. Thank you all for the great info.
