iPhone removing cydia

[tryu32]

im using an iphone 7plus IOS 10.2.1
I had cydia on my phone but it stoped working (crushes as soon as im trying to open it)
I really want to remove it from my phone if it doesnt work, i tried reseting the phone with out back up and its still there,
if i want to DFU im required to update the phone which dont really want to do...
how can i remove it?

In addition is there any way to partilly back up only my contacts and photos so if ill be able to remove it i can still have my folders with out the jailbreak/cydia?
thank you

How did you jailbreak it in the first place? For example, when I used unc0ver on my 6s, and it got patched, I used the same app and within the settings there was an option to remove the jailbreak (including cydia)

Can you try another JB method if you want to keep your JB? https://pangu8.com/jailbreak/10-2/
