Fixing
Red screen or freeze during a game
updated Oct 29, 2026
During a game, a piece of the app code (usually the video decoder) shows up altered in memory and the app freezes or shows the red screen. Since 0.21.39 a guard checks and restores the code all the time, which greatly reduced the cases; it still happens when the altered part runs before it is restored. We are tracking the cause with the records the app saves.

Built-in Wi-Fi does not start on some consoles
updated Oct 29, 2026
On some Xbox 360 S/E consoles the app cannot find the built-in Wi-Fi adapter ("not on EHCI"). 0.21.43 already made Wi-Fi turn on from the menu after starting with a cable and retry after a failure. On the consoles that still fail, the adapter seems to be on a USB port the app does not recognize; 0.21.44 shows what is on each port on the error screen so we can identify it. Meanwhile, use a network cable.

Input and video delay
updated Oct 29, 2026
We measured the delay inside the console: each frame spends about 55 ms in the decoder, because it uses 4 threads at once to hold 60 FPS at 4 Mb/s (with fewer threads the delay drops, but the picture stutters in heavy scenes). Reducing it requires changing the decoder and is being studied. In some games the feeling of aim delay comes from the stick dead zone: adjust it in Settings > Controllers.
Testing
Beta key does not activate or the app asks for it again
updated Oct 29, 2026
Almost all cases came from generating a new key (each new key disables the previous one) and from a USB stick that does not save (front USB port). The site now shows the current key and tells you to always use the same one; 0.21.44 shows on screen when the key was mistyped (keeping what you typed) or was replaced on the site. Use the USB stick in a back port.

Update goes back to the old version
updated Oct 29, 2026
When the app asks to restart and comes back outdated, XeLL is opening another xenon.elf (from another USB stick or the HDD), not the one the app updated. Update by replacing the xenon.elf that XeLL opens, without deleting the XC360 folder. We are looking at how the app can detect and warn about this.
Fixed
Freeze at startup with USB devices
updated Oct 29, 2026
The app froze at startup with certain USB devices (wired controller, receivers, accessories that do not respond). Fixed in 0.21.41 and 0.21.43. Still recommended: USB stick in a back USB port, and plug the wired controller in before turning on the Xbox or with the menu already open (not during the startup screen).

Fixed
Match logs did not reach the team
updated Oct 29, 2026
What happened inside the game was only sent if you stayed in the menu afterwards. Since 0.21.43, when you leave the game the app shows "Sending the match log" and sends everything in a few seconds. This helps solve your reports.

Outside the app
1080p unavailable or picture in 720p
updated Oct 29, 2026
xCloud sends the video in 720p to the app. 1080p output only exists on Corona/Winchester boards and upscales that picture; older boards (such as Trinity) stay at 720p. Sharpness depends on your internet: with an unstable connection xCloud lowers the quality.
Outside the app
Third-party (non-original) controllers
updated Oct 29, 2026
Third-party controllers do not work in the app yet. It is noted as a future feature, with no date. Use an original Xbox 360 controller.
Outside the app
Session ended by xCloud
updated Oct 29, 2026
Messages such as "xCloud ended the session" (for example KickForAppError) come from Microsoft servers: the game failed in the cloud or the session expired. Open the game again; if the next one does not open without restarting the Xbox, send a photo in your report.
