Cydia won’t open, what can you do?


The most frustrated thing in life is nothing but Cydia won’t open after you have spent hours to download and install it. You have spent hours to read how to install Cydia to your iDevices; you have followed the steps by steps clearly; you make sure that each detail in the instructions is done but it just does not work on your device. What the hell? What could be wrong and what should you do? Just like anybody else, the first time I try to install Cydia to my iPhone 4S, it was failed due to several reasons. I have also followed exactly the steps shared in some websites but my Cydia just won’t open after I tap on the brown icon. Here I am going to share you several experiences why Cydia won’t open although the installation process seems to be perfect.

Cydia won't open

A very common problem that anyone may experience is when you tap on the Cydia icon after you have jailbreak your iDevice, the screen flashes a few times but Cydia doesn’t open. Frustrated huh? If you experience this, your Cydia won’t work no matter how many times you tap on it. First of all, check if there is something went wrong during the jailbreaking process. Everything may look perfect during the installation but sometimes Cydia server could be down when there are too many connections to it. If you make sure there is no problem with the jailbreak, it could be Cydia is not properly installed or it is not completely installed to your iDevice. Check on Cydia not working for more error details during the installation.

Incomplete installation is a common issue. However, if you have tried to rejailbreak or reinstall Cydia several times, it is something else. I used to tethered jailbreak (jailbreak your iDevices using a computer connection with jailbreak application such as sn0wbreeze or redsn0w) my iPhone and the same thing always happen to me – when I click on the Cydia logo it just don’t open but flashes a few times. This is because I did not boot tethered my iPhone and cause the device living in “unjailbreak” or semi-tethered status. The symptom of semi-tethered is when you tap on the Cydia icon, it flashes few times and closes back up or the screen goes black or white and then jump back to homescreen or it just won’t open and crash. If you come across these symptoms, your Cydia won’t open no matter how many times you restart or reboot your iDevices. To solve this, simply connect or tether your iDevice back to your computer and boot it with the aid of the jailbreak application you use. If you are using redsn0w, try to run it again and check on the “just boot tethered” box. This method works perfectly for me every time my Cydia is not able to open after jailbreaking process.

My iPhone is Untethered Jailbreak – just can’t open Cydia to unlock and get service up. Tried the Jailbreak ‘Just Boot’ also – no result.
Any other suggestions?

I used greenp0ison to jailbrak then I had to download Cydia from an app called loader and when I went to go open the app it wouldn’t open it would flash like it was about to then it just doesn’t…??? Why?!?!

Hi! I have an iPod touch 4 and I jailbroke it today, later I downloaded a tweak that asked me to restart the device and then when it was restarted it was like unjailbroken. Once in the PC with redsn0w i tried to just boot tethered and it took much time and didn’t boot and a message said that something was missing.

i jailbroke my ipod but then cydia wouldn’t open. i tried to “just boot” it with redsn0w. i had a loose usb plug-in and it accidently unplugged. it said “exploit failed” and when i tried to put my ipod into dfu mode again, it went into soft dfu mode instead.

i know how to get it back to a normal functioning mode, (so it’s not just a black screen/ or recovery mode).

i’m just not sure how to boot it with redsnow, or what i should do to eventually get cydia to open.

I had installed Cydia and it was working fine, I downloaded an app, everything was good until I tapped on the Cydia app once and there was a flash of black, the screen would shake a little bit, and it wouldn’t open. I rebooted, but all that achieved was making it so I couldn’t even open apps I had installed with Cydia. I have hard rebooted several times and nothing has happened. It is starting to really annoy me.

I have an iphone 4s 6.1.2 in a semi-tethered state. It was jailbroken with Evasion and the Evasi0n untether package disappeared. I CAN’T use Redsnow for obvious reasons. And Evasi0n tells me to install the untether package using Cydia, which, (catch 22) won’t open. And using ifunbox to install the .deb (media/cydia/Autoinstall) won’t work either. Any ideas???

“It was jailbroken with Evasion and the Evasi0n untether package disappeared” ? How come the untether package disappeared while you said you jailbreak with Evasion? I believe there is a problem occurred during your jailbreak. Without the untether package you can’t install Cydia therefore how can you use Cydia to install the untether package? This results your iPhone 4S get the catch 22 won’t open error. You should re-jailbreak it and try again.

No, no no. I jailbroke it with evasion and it worked fine, for a long time. Then one day I was installing something from cydia, which required a reboot, rather than a respring. When it rebooted, it seemed to be stuck in a boot loop, for about an hour till it finally booted up, but the evasion untether package was gone. I tried to rejailbreak it with evasion, but evasion just tells me “error: your device appears to be using a semi-tether jailbreak, please use the evasion untether package from cydia to untether instead!” but I can’t open cydia, and using the cydia autoinstall doesn’t work either.(I was the one saying its a catch 22, not the program) unfortunately, I don’t have ssh setup on my phone.either.

Hey Sarah, since your iPhone is in semi-tether jailbreak mode, I assume you have the iOS 6.0 ipsw. If you know how to use the DFU instructions you can untether your iPhone and then just boot. After your phone boots up, you should be able to open Cydia. Let the phone completes the initializing filesystem. Tap Search in the lower right corner, find and install the evasion untether package. Reboot. Finger crossed! If this is not working, try restore and setup your iPhone as a new iPhone, jailbreak again and then restore from iCloud.

My ipod is jailbroken with sn0wbreeze, i just jailbroke it today, now whenever i try to open cydia it seems like it opens for half a second then immediately closes, can someone give me detailed instructions on how to fix this please?

none of these worked because i use snOwbreeze so i did a little research and i found that if you reboot with iBooty it works so here you go 😀
