iPhone music vanishes with Apple's iOS 4.2, hackers release 'jailbreak'

post #1 of 39
Thread Starter 
Some users have found that updating their iPhone to the latest software version, iOS 4.2, has made their iPhone music disappear, though a quick fix is available. Also, hackers have quickly released a "jailbreak" for the new mobile operating system update.

Quick fix for vanishing iPhone music in iOS 4.2.1

Since the release of iOS 4.2 on Monday, some users have experienced disappearing music on their iPhone. A thread on the Apple Discussions forums has found that the music was not erased, but needs to be re-synced.

Some who posted on Apple's forum have found a fix for the issue that seems to work. User "slouchsock8" recommended the following method:
Connect iPhone to iTunes via USB
Play a song on the iPhone itself from iTunes
Click the "Sync" button to re-sync the iPhone
Open the iPod application on the iPhone to rebuild the music library
The latest software update was released as iOS 4.2, but is technically iOS 4.2.1. iOS 4.2 was released to developers as a beta earlier this month, but issues with Wi-Fi connectivity forced Apple to build a second golden master with fixes before public release.

"Tethered jailbreak" for iOS 4.2 released

Hackers quickly released a software "jailbreak" for iOS 4.2 after the update was made public Monday. Jailbreaking is a practice that allows users to run code not approved by Apple on their mobile device.

A group of hackers known as the iPhone Dev-Team released the latest update of their hack, dubbed "redsn0w," with version 0.9.6b4. It is available for both Mac OS X and Windows.

For recent devices -- the iPhone 4, newer iPhone 3GS models, latest-generation iPod touch, and the iPad -- the jailbreak, for now, is "tethered," meaning users must reconnect their device to a computer via USB to re-jailbreak if they need to restart it. Users of the iPhone 3G, older iPhone 3GS models and second-generation iPod touch (models numbers that don't start with MC) can have an untethered jailbreak.

Apple and the hacking community have been engaged in a cat-and-mouse game for years, as Apple looks to plug security holes and hackers find ways to exploit them. Jailbreaking allows users to do things with their iPhone Apple and its carrier partners do not allow, such as custom themes and icons, "true" multitasking with applications running in the background, Wi-Fi tethering, and FaceTime over 3G.

Apple has primarily expressed concern that jailbreaking allows users to steal software from the App Store. The Cupertino, Calif., company has also cautioned that the jailbreaking process, while legal, can make iOS devices less secure.

This happened to me too. Not only did music not show up but movies and podcasts as well were absent. Well, not absent, the files are there on the phone. But for some reason, the phone doesn't think they are there. I solved it by asking iTunes to remove the 4 movies I had on the device and then syncing. Then I put the movies back on and synced again. That solved all my problems (music, movies and podcasts). Given the solution offered in the article, the updating of any of the media files seems to fix the problem so the simplest way to do it is tickle one of the music files by playing it on your Mac/PC.

BTW, this problem has happened before to me with a previous major updates, and fixing it was pretty much the same as I described above.

The vanishing music issue is at least now consistent with the vanishing video bug that the iPad has suffered from for months, where videos are copied across but sometimes don't show, requiring a re-sync.

Lost my music and solved it with a re-sync.

Contacts and calendars were not updating as well so I deleted my MobileMe account from the phone, selected yes to delete data on the phone and then set up the MobileMe account again.

Now... on to figure this AirPrint thing!

Yeah, just a simple resync. Don't need to do the "Play a song on the iPhone itself from iTunes" voodoo.

Power off/on worked for me.

Didn't anyone at Apple test this before they released it?

I lost my phone while upgrading to 4.2.1 - it bricked.

I had to replace it at the Apple Store. They were very very nice and accommodating and even though there was no genius appointment available they helped me out.

What happened (according to the genius) was that the communication with the Apple servers was lost while the firmware was being upgraded and that caused the phone to brick. Why is this communication required is beyond my understanding.

Needless to say I am happy to have new working phone again.

In a way though I am also a little upset with Apple. I pay premium prices for a premium experience. This was not one of those moments. I hope they are going the Microshit way!!!!!!!

Well this stupid update forced me to upgrade to iTunes 10.1, and now OS X runs slow as hell...

I'm sorry you had troubles with your upgrade process. Whatever the device (computer, iPhone, etc), we always want (and hope for) a smooth experience.

But being mad at Apple for not providing a 'premium' experience is a bit unrealistic. That's like buying a $100,000 Mercedes or BMW, and expecting it not to suffer the same mechanical issues inherent to any car. In the end, it's still a car, and things can go wrong with it. And the iPhone is a computer, that can suffer corruption like any other computer.

The premium experience is that you were able to take it to an Apple Store and have it swapped out painlessly. Try doing that at Best Buy or anywhere else...

I also have had this problem a few times. I find that simply transferring one more song onto the phone seems to work pretty well...

now to figure out what my apple login is...

Not to go on a tangent but YES - the apple login system is wacky. It requires an email format name but using one's email address doesn't work (nor does using one's apple ID). I think integrating apple IDs and mobileme is being done a little more quickly than it should be - at a minimum, you would think they would post instructions about how to associate an email address with an existing apple id.
post #12 of 39
yes. simple re-sync (took about 10 seconds as there was no new information to sync - I don't use dynamic/random playlists).

I think not as we had the no media problem with two iphones and an ipad. Was scared for a few minutes until I resynced and everything came back in several seconds.

Just out of curiosity, is the computer you were updating from a Mac or Windows machine?

On Windows, ZoneAlarm (and possibly other firewall/AV software) is a frequent cause of problems, particularly with OS updates.

When I updated my iPhone my Music was missing and a simple re-sync did fix it.

However my wife's phone updated perfectly with no hiccups at all!

I am unsure of what the differences are, other than I had some podcasts and she has none.

Does anybody see a nexus between these two stories? "some users" have a problem. Jailbreakers. Jailbreakers steal software. Apple tries to protect its developers. Spple doesn't like criminals mucking around inside their devices. "Some users" have an experience with an Apple product which is different from the Apple User Experience.

Who are these people who claim problems? Jailbreakers? Criminals? Jailbreaking allows users to steal software from the App Store. Jailbreaking makes Apple's iPhones less secure. Apple tries its level best to protect the Apple User Experience for the average user.

Exactly. But simply turning off/on didn't work, will have to sync later after work.

Wait a second... The genius told him communications between servers and his phone were dropped while updating the firmware. This is pretty strange!

He must be talking about downloading the update file, not the process of applying the update. If the file was corrupt by a little, it may still be able to run, but this is why you see installations say things like "validating files" before running, which the apple update should have done and eventually caught the error in the file.

If a connection to the internet is required to APPLY the update, that in itself is bizarre as well.

I bet it could have been fixed with a simple dfu mode reboot

That makes no sense.

For one thing, many people with non-jailbroken iPhones had this issue (although, it barely reaches issue level, considering how minor it is).

Besides, jailbreaking is not illegal, so I am not sure where the criminal angle comes in.

Not for anything, but Jailbreaking by itself is legal. Not everyone Jailbreaks to steal software.

Case in point: I have an iPhone 3G. I can record video with Cycorder, I can free up memory with SBSettings, I can mark all my mail as read with PopMark, and I can run command-line from MobileTerminal. None of these can be done with an "off-the-shelf" 3G. Does this make me a criminal?

Yes there is some JB software that may conflict with other stuff (like backgrounder) but a lot of apps in the Apple App Store have reviews like "buggy" and "crashes" too.

Jailbreaking makes the platform more open by removing the limits imposed by the manufacturer, and yes, therefore, creates the *potential* to steal/pirate software. But it doesn't *make you* steal software.

Syncing the iPhone after the update is all that is required. Only my music was missing from the iPod app; photos, and other apps were still functional.

As for jailbreakers, eh, w/e. They just find the holes Apple needs to secure and they develop functionality that Apple eventually adds in their own, possibly more stable, way. I just hope developers aren't hurt too much by pirating.

After the sync for the newest iOS, a pop up on my Mac told me over 100 issues with missing music. After poking around in mail and phone, a pop up on my phone told me my .me pass was wrong and asked me to re-enter it, then my voice mail said my pass was wrong.

I don't have a jailbroken phone. Just a 3GS with a few apps and 16 gigs of music.

I synced after playing a tune from within the iPhone music via my Macbook Pro, but missing stuff is still reported and my passwords are still missing.

sure I can experiment with wiping the various apps, or the whole phone, and syncing again, but why should that be required? I'm no slouch, but I shouldn't have to jump through hoops to reclaim a normal working environment after an incremental upgrade.

Whatever. I have a jail broken phone. That is a necessary step to unlocking it. Once I buy the hardware, Apple has no say in what I do with it as long as I am willing to suffer the consequences of a voided warranty. T-Mobile is a million times better in my area in terms of customer service, call quality, and pricing.

Further, I have heard stories you can steal software from the Apple store with a jail broken phone. That was a while ago. I certainly do not how to do it. I suspect most people jail breaking just want the phone unlocked to use on other networks. Perfectly legal.

Yes, for Windows or other update mechanisms which have to contact the Internet during the update process. AFAIK after iTunes downloaded the new firmware it is transferred to the iPad via USB so Zonealarm or any other firewall is unlikely to be the culprit.

To restore the music library you need only to sync & open the iPod app, which displays Updating Music Library . This will take only @ 2 mins for 2,000 + titles

I never had my ipod jailbroken. Don't see the purpose anyway since i am perfectly happy with the way it works out of the box.

After the update, though i still had my music playlist disappeard. However, as others said, easy fix by resynching the devise with itunes.

Next step. getting the iphone through my mobile network !!!!!!

Do not attempt the jailbreak yet. Especially on the iPad...
Number 1 it is a tethered jailbreak.
Number 2 if you install some things through Cydia you can only boot tethered through Redsnow and you may not be able to boot normally.
Number 3 they are still working out things like Mobile Substrate and so on. Give it time. Within a few weeks many of the various devs will get their stuff up and running with Cydia etc and hopefully there will be an untethered jailbreak as well. I give it at least 2 weeks for the dust to settle.

Redsn0w+3G+4.2.1=all good. I'm running it now. Cydia works. Activator complains.

Come on man, that's not right. Apple is big now for a lot of reasons, and a big one is that it's less buggy than other platforms. That stability and predictability is definitely part of the premium experience.

Cool. I need Mobile Substrate and Veency to work properly, it doesn't seem to be doing that yet. And I need DisplayOut which is not yet supported on 4.2, the developer is on vacation or something. Argh LOL.
