iPhone Is it possible to brick iPhone while jailbreaking?

[Brandonjr36]

im wanting to jailbreak my X but I don’t want to risk bricking it. If I go ahead and jailbreak it and something like that happens is there away to unbrick it? Sorry about the stupid questions. This will be my first time jailbreaking anything...

 

[Adam.Kb2Jpd]

Anything is possible with an X.

First backup anything you consider important. Do the computer iTunes backup and the iCloud backup.

Read the instructions twice so there is no misunderstanding.

Download the actual pristine jailbreak from the original author. You download from elsewhere expect nothing but headaches afterwards.

Jailbreak, expect a lot of Apple software to break because they check to see if the phone was jailbroken.

Expect your phone to get sick.

That’s it.

I hope you have a backup phone because a lot of tge code in jailbroken apps are beta and will act strangely if you are using a ios beta.

It can happen, if you try really, really hard. I suggest a sledgehammer.

This is not 2007 where an 80+ series of steps and arcane hardware can render your device screwed. If anything happens, a DFU mode restore will take care of it.

Ahh…the jailbreak hater type rears it's head!

First, yes. Anything is possible. Unlikely, but possible. Second, you do actually suggest a good thing. A backup. But then the rest of your post derails into anti-jailbreak rhetoric.

First off, there is more than one tweak that that will cloak jailbreaking. And usually it's banking apps that have a problem.

Your phone is not going to get sick - unless you put it into a spot to be sick by being dumb with it. Shady repos, pirated tweaks, going around to suspicious websites, etc.

Jailbreaking in and of itself does not make your phone "sick".

As far as beta code, there are a lot of tweaks that are NOT in beta. You're just applying a generalization here.

 

[TriJetHero]

As there is no Cydia and no substrate at the moment, there is no up to date cloaking for the jailbreak either.
Not only banking apps use jailbreak detection, also media platforms such as DirectTV, games etc.
Just like jailbreaking itself, cloaking is a cat and mouse game where app makers update there apps to break cloaks.

As the jailbreak is still hardly out in the wild some hickups are expected and many tweaks don't work and need updating.

That also means that if you do try apps it might endup going in a loop requiring a DFU restore which means going to latest iOS and losing the ability to jailbreak.

At the moment I advise against jailbreaking for newbies, just be patient and let the tools update and work out the problems.

@eyoungren... we have 'crossed swords' before on the forum, I appreciate your inputs but I miss the caution in your advise to the newbies, when I was more active here I always pointed that out, I love jailbreaking but it has drawbacks and risks.

Yes, yes it is. As to unbrick it, that will depend on what happened.

Again. This is not 2007. Hell, none of the jailbreaks for later iPhones (including the X) are even fully untethered!

Unless you are trying VERY hard to brick the damn thing it's not going to happen.

Perhaps however, there is a misunderstanding of the word "brick" when it applies to a device. The word literally means a brick. You can do nothing. The device responds to zero input. It does not turn on the screen, it does not flash the Apple logo, it doesn't do anything at all. That's a brick.

Lately, the definition has been redefined by people who lazily apply it to mean a boot loop or a glitch or something similar. That is NOT a brick!

As long as you can enter DFU mode and recover the device, it is not bricked. And again, to get there you have to be trying extremely hard to screw it up.

It is possible, but it is not anywhere near probable.

You really need to evaluate jail breaking. Although it’s hard to do, the risk is there. You are writing into the OS new code to bypass Apple’s walled garden.

Not talking of the risk is simply (for lack of another word) risky behavior.

Sigh.

There is risk. I do not deny risk. I never said I did. Read back. I said bricking was possible - just not likely.

Today's modern jailbreaks are not like it was 10 years ago.

As far as re-evaluating jailbreaking…no. I've been doing this since 2011 with iOS 5. My current iPhone has been stable on a 9.0.2 jailbreak since October 2015. I don't see anything that is going to prompt me to stop - except switching to Android later this year.

Well the message I am trying to convey is not coming across, that could of course be in the sender

An experienced JBer probably can get out of a 'brick' situation, but I have seen plenty of posts here of people that are even unable to get in to DFU, that makes it a hard brick for them and they might have to seek external advice, costing them money and time.

What is obvious for you might not be obvious for others, so I always kept that in mind when advising people on stuff like this.

All current available JBs for iPhone X are in beta, so no it is not easy and there is risk

From the LiberIOS website:

And yes, Code injection works, but CYDIA WILL NOT BE SUPPORTED. EVER. So please don't ask.

From the Electra JB website...doesn't sound easy to me...and then it probably is not easy...

I’m gonna wait for cydia.

I’m gonna wait for cydia.

Just for your comfort, I have an iPad pro on 10.3.3 which is jailbreakable but I'm waiting also for it to get more stable
