How to stop itunes from deleting all of my apps???
« on: November 22, 2010, 05:15:41 pm »
I decided to sync my itouch for the first time today, it made a backup, and then it started deleting apps. I unplugged the cable. Is there a way to recover those apps from the backup, and then not have itunes delete them again? (If it makes a difference, I got my apps using "questionable methods")

The questionable methods is probably your problem.  But yes, you can.  In the main menu of your ipod, around where the update button is, there should be a restore button.  You can restore to a previous backup that way.  I would like to know more about these "questionable methods" as this may cause that method not to work.

Wait, you've jailbroken it. Yeah, you might not be getting that backup.  Try the method I suggested, though.  It should work.

I still have the backup files. Is there another program I can use to restore my ipod with?

Not that I know of.

Is that an anti-jailbreak protection causing itunes to take revenge against you?

No, it's probably trying to update the jailbroken device the same way a normal device is, but if he's got apps that are not signed by apple (as apple does the signing before releasing it to the app store) then they aren't valid, and so iTunes tries to get rid of them. If they are signed, then there's no problem.  Apple probably uses some form of SHA-2 and RSA(some public/private key algorithm)

Note that this is just speculative right now.

Wow, that's worse than TI O.o

I have a friend who got his apps cleared too when he updated, too. Don't know how to stop it from happening :-\

Don't update. It's as simple as that. Later safe procedure will probably be found.

This is another leasson IT industry is busy teaching to users: since upgrades tend to block/remove all "unapproved" features (Apple is not an exception: Microsoft, Motorola, Nintendo, SONY and others are just as guilty) users are slowly learning to distrust them. This is defenitely bad for security, but when upgrades remove even advertised features (think Playtation3) it's hard to blame users.

Include Texas Instruments in the list above too. They added an anti-downgrade protection in TI-Nspire OS 2.1, because OS 1.1 and 1.7 allowed ASM/C programs to be ran. :P

The jailbreaking scene is a neverending war between the big greedy company and the 3rd party programmers.

send all your ipa's to itunes, put them in a separate folder, update to the next jailbreakable version of iOS, put all your ipa's back on your device by SSH and install them because itunes might delete them, or install Installi0us and appsync, and then sync. But you shouldn't be using install0us. Morally and Ethically wrong. Buy the apps instead.

Now hold up, companies aren't always "big and greedy".  Those big companies are what makes a strong economy. They have reasons for their decisions.  Think of it this way, DJ. as an admin, you make choices that affect this site. Because it is your site, you want it to do well. That is your motivation for keeping things out that you consider detrimental to your site. It's the same with companies.

Sorry, but the whole "profit and big companies are bad" thing really is a sore spot.

I wonder what method of signing it uses though. If we got a signed vs. Unsigned copy of an app, I could probably figure out.

I guess the question boils down to is this:  you said you got apps through questionable methods, did you get them for free while you would have to pay for them normally?

Yes, they are.

They have reasons for their decisions.  Think of it this way, DJ. as an admin, you make choices that affect this site. Because it is your site, you want it to do well. That is your motivation for keeping things out that you consider detrimental to your site. It's the same with companies.
Sure. They can do whatever they want. They can even ask me to obey some rules if I want to use their site. But WTF they pretend they have right to dictate what I do in my home? I've bought the TI-Nspire and fb39ca4 bought the iPad. I have an invoice. It's mine. Why do they have the need to try to criplle the thing they no longer own? It's as stupid and immoral as the futile try of DJ to dictate what I should write in my love letters. There are few noble reasons for that (think spyware removal tools), but then main reason to do that is: to try to extort more money from me. This is greed - not noble at all. When PlayStation3 forces me to buy new controller to play online - that's greed, when TI forces me to spend money for Nspire CAS and closes the way for third-party developers to develop CAS package - that's greed, when Motorola says "no more updates for you, buy own new model" - that's greed too.

All companies start small and helful and become increasingly hostile and harmful with time because of the greed. But there are different degrees. When Intel refuses to give nVidia right to sell chipsets - it's one thing, it's greed and it's bad thing, but it does not affect me directly, but when Apple or SONY or Texas Instruments decide to say what I can and can not do in my own home - that's just over the top.

I guess the question boils down to is this:  you said you got apps through questionable methods, did you get them for free while you would have to pay for them normally?
Yup. That's good question too: if it's some banned applications whuch Apple just does not like for one reason or another - it's one thing, if it's programs which are distributed against author's wishes - it's another thing.

But the end result is the same: people are trained to guard their property and reject upgrades when in doubt.

Include Texas Instruments in the list above too. They added an anti-downgrade protection in TI-Nspire OS 2.1, because OS 1.1 and 1.7 allowed ASM/C programs to be ran. :P

Hmm... The link above says that you still can use OS 1.7 after upgrade, only 1.1 is disallowed. And OS 2.1 has some new features too. Compare this behaviour with Microsoft, SONY, or Nintendo: these companies published upgrades which had one and one goal only: to cripple your lawfully-owned device.
