Not tvos 
, also chimera still cant jb 12.1.2-12.2 (tvos) hes waiting for the first user to tell him that it works, it must work he tells, while many posting pictures showing that it does not work.
@AlexManCH ChimeraTV 1.2.2 supports up to tvOS 12.2 on the Apple TV 4K, but the 1080p Apple TV 4 is only supported up to tvOS 12.1.1ā¦
Yeah but it doesnt work unfortunately, not one positive feedback so far. Everyone is getting jb failed message in chimeratv app.
@AlexManCH Restart and try againā¦ If your AppleTV is supported, the jailbreak process may still fail (even many times!) before working onceā¦
On iOS I had the same problem whenever I tried jailbreaking with Chimera, and it took sometimes 20-30 attempts to get it to finally work!
I donāt know what is the exploit itās using but you should maybe try with wi-fi turned offā¦
Well i tried like over 50 times without success and now after waking up, i was ready for more trying but somehow i found that bloody thing updated to 12.3 
I for sure tried 10times without wifi yesterday.
Dont know for now if im going for a third one just to be on <=12.2 to maybe have still no success
@AlexManCH Damn those automatic updatesā¦ 
I personally hope to see a jailbreak drop when iOS 13 releases, as there are some cool features like the PS4/Xbox controller support and some things Iām looking forward toā¦
Hello, I jumped over to this thread from the one you had told me was old, lol. I downloaded RetroArch IOS 11+ from your repo, but it doesnāt have any cores installed. I tried using the online updater and it looks like it downloads the cores, but when I try to select a core it tells me I donāt have any. Iām completely lost. If you can lend me a hand I would appreciate it very much.
@FlashyLatin What is the file extension for the file youāre trying to load ? And what core(s) did you download ?
Cores look for a compatible file before showing up in the core selection menuā¦
When you go to online updater/core updater/select core to download. Are you then supposed to do something else? Because I was thinking it should then show up as a downloaded/installed core.
I downloaded both PlayStation cores. I donāt have any cores for me to even try a file extension to try a Rom. Not sure if thatās what youāre asking.
@FlashyLatin It goes something like this :
-
You choose āOnline Updater -> Core Updaterā and you pick one (for example, as I included Cave Story in the ROMs folder, you could download this core for a test, so you pick Cave Story (NXEngine))
-
After it goes to 100% and installs the core, you select āLoad Content -> Start directory -> Cave Story (NXEngine) -> Doukutsu.exeā
It should work about the same with any core you download, but you can try the āLoad Coreā option to see if it gets populated after downloading any coreā¦
Hope this helps ! 
Thanks for helping our. I promise Iām not making stuff up. But when I select game story from start directory - Cave Story, another folder pops up that says data, I select it then 2 folders pop up NPC and Stage when I select either I get to a dead end saying no itemsā¦ What I doing wrong? Is there a way I can send you a video clip or some screen shots so that you can get a better idea?
@FlashyLatin It should look like this (this is on my iPhone X, iOS 12.1.2, Unc0ver jailbreakā¦)
Notice that after I download the core, it now appears in the āLoad Coreā menuā¦ Then āDoukutsu.exeā is selectable in the āLoad Contentā menuā¦
After I download the core and go back to load cores. I get a āNo Items) with āLoad Core (No Core)ā crawling at the top. It seems to be downloading the core, but then it doesnāt populate it for whatever reason.
I did have the other version of RetroArch from your previous post (that you told me was an old thread). It was also 1.7.7 but that version had all the cores pre-built, the problem was I was getting a little yellow message at the bottom telling me, āfailed to open libretro coreā.
I donāt know what else to tryā¦
@FlashyLatin Try to delete RetroArch from Cydia, then download the āRetroArch Cleanerā from the repoā¦
After that, delete RetroArch Cleaner from Cydia and then download āRetroArch (iOS 11+)ā again from the repo !
It will work if all goes according to planā¦ 
Nothing, I even downloaded RetroArch from my mobile data, since Iām not at home with WiFi just to try. It still doesnāt show any cores installed. I followed your video up there to the T. Is there any way to use a program like Filza to manually install the cores by copy and pasting from downloads?
@FlashyLatin Even with the RetroArch Cleaner it didnāt work ? Iām stumpedā¦
Yeah, you can download cores from the iOS 11+ buildbot and drop them in ā/Applications/RetroArch.app/modulesā folder with Filza!
I donāt know what happens with your installation thoughā¦ What version of iOS are you on ?
I saw your buildbot at the top and downloaded one of the files. It was PSX, I used Filza to copy it to the modules folder, but no go. Do I need to unzip the file, rename it, or anything? Since itās not showing up as a core.
@FlashyLatin Yeah, unzipā¦ RetroArch does it upon installation of the core so the buildbot must be configured that wayā¦ You can unzip with Filza too!
What iOS version are you on BTW ?
Iām on IOS 12.0.1 with Chimera JB.
