iPad Safari crashing regularly

I do agree with you it is highly unlikely that this is a virus however in this case it is a good change.

A small cache or cookies based virus called worm$i##OS2598cacheregisterycode8730091.

DFU mode reinstalls everything on your device including ROM and anything else on your device.

You pretty much have a dumbed device if the power goes out.

But it is usually very safe as it is a Apple command.

It will reinstall everything.

Usually the virus does not back itself up.

If it does usually the only way is to go through the whole process again but just set up as new device.

Shout if you have any other questions

This may be a good idea.

I still doubt a registry worm is the cause, if indeed it is a registry worm as that only exists on windows.

A restore has worked for almost everyone in this forum to some degree, without entering DFU.

It will automatically go into DFU if Restore fails.

DFU mode is a form of recovery mode. It's full name is DFU full hardware core recovery assistant mode.

This worm worm$i##OS2598cacheregisterycode8730091

Is known to attach itself to the ROM bootup priority thus making it a high priority to system to have it startup.

It disquises itself in the form of a system process.

Apple release iOS 5.1 today. Dealing with this issue.

Myself and my team have a copy of this virus as HTML .jpg and .BTOS

We have taken this worm apart and we were one of the first 5 to discover this issue...

5.1 Automatically removes this if it has not gone as far as the ROM.

I do think it is a good idea to enter DFU as 5.1 is not availeable to the consumer yet as it is still in its beta stages.

.BTOS is like a CMD command on windows [program form .bat]

DFU recovery assistant mode is currently the only a good shot you have.

Some devices are experiencing battery life problems due to this.

Tiaan, could you share these files?

That voids myself and the teams rights to exploit the software if we are caught

I've tried the restore option many times and I still have problems with my ipad crashing. It crashes while using safari, as well as, with other applications, primarily with mail and, facebook (but it does crash with other apps - just not as often. Mine is an iPad 1 and I've tried it with cellular on and off.

So this so called cookie/cache virus (what is a cookie/cache virus btw?) was released the very day apple released 5.0, it automagically infected pretty much every iPad out there, nobody knows about it, it can outlive a device reinstall, there's a 0-day in safari's "HTML jpeg" decoding code, you're one of the 5 few happy people who will soon be famous for unraveling a critical issue in a core component of the most popular tablet, and the first thing you do is come on an apple forum to mention it?

Can I be skeptical?

In the meantime, pretty much all affected devices are logging "Out of memory" crash reports for safari like there's no tomorrow, and we're in the midst of an iCloud debacle where 5.0 managed to take battery life down to single digit, 5.0.1 didn't exactly fix the problem, but softened it and made it available to everybody.

I'd rather go with the pragmatic approach: 5.0 and/or safari 5.0 are using too much ram for the iPad 1's 256MB, and Safari crashes because the device simply runs out of memory.

Or the ipad 1 is affected by a subtle iCloud bug, like the iphones are.

I vote for option 1, my ipad 1 is definitely much slower since the 5.0 update and it looks consistent with a "no ram is available and the cpu isn't powerful enough" problem.

Hopefully apple will fix it with 5.1, or 5.2, or maybe never, you never know what's their next move.

First of all, this virus theory is ridiculous *and scary*.

If it is not fixed with a restore and setup as new ipad, it is in fact a hardware problem, and should be treated as such.

The Google Plus URL was the rare time I could reproduce this problem.

Apple would not be able to sell ipads with this flaw. The warranty's a year. They would get returned.

Again like I posted before. Doing a complete DFU RESET, fixed my iPad crashing problem . After I advised some family members the same they could fix it cause they were doing it wrong.

This must be done correctly. I did it and mh iPad is back to normal

I have no objection to doing a dfu restore. I have objections to the theory sorrounding it.

I have to say that Im neither a programmer, nor an engineer, and as such, while I feel perfectly comfortablem with most aspects of computers, including Ipads Im mostly a user, and just need my computers and ipad to simply work.

This is the first time that anything that I have had with the apple logo, has somehow failed or crashed on me. So I was taken back by it, but after some research I finally got someone at Apple to help with this, and sure enough, the DFU reset, and new ipad setup has worked. My ipad has never crashed since then.

So I dont know what was behind the crashes, whether it was some sort of virus, but I could say that it didnt happen prior to my update to 5.0 Even after I updated to 5.1 it still was crashing.

So this has worked. The reasons behind it, or the analysis part I'll leave to the experts..

George

I wonder Jobs was still around and he could not post because his iPad kept crashing if there would not be a fix out by now...

There is nothing inherently controversial about a DFU restore. It is a restore that's deeper in a way than a conventional restore, designed for if restoring fails. I am not an apple employee, nor certified (yet). But I think it is safe to do.

You should try a regular restore first, in my estimation if you are planning on trying this. We just want to try the least invasive procedure first.

Please, other people should comment if the dfu restore works for them where regular restoring fails. And thank you for bringing that to my attention. I had heard about DFU of course, but never really understood it.

I would also ask that people follow etiquette and not post things that aren't directly related to solving the problem.

Thanks.

P.S I also applaud novice users. Welcome. And I'm glad you got your ipad back. You're right -- theorizing isn't very useful. The actual solution is much more important.

Sorry Sam I don't really like correcting people as I know I don't like it. I am sticking to my theory that this is undead a worm and I am sticking to that theory because wether you guys like it or not it is out their. The worm slowly but surely changes things in your file system. When you do a usual restore these files are just reinstalled. The work is dormant inside the ROM and When you boot your device it is said to be a priority file. The usual restore is just a temporary fix. DFU mode also reinstalls the ROM (which is on a seperate chip).

Guys please I am not making things up. Please Dam I am typing my but off and all I get is to be told that I am wrong. I know in this day and age you have to be careful but I bEg you to believe me!!!!

Begging is not going to do you any good, come up with a compelling technical argument rather than vague technical, plot theory-ish giberish on top of "I swear to god, my weird theory is true, I just can't prove it", if you want some credibility.
