programm not installed on the iPhone, unknown error Code 0xE8000001

I experienced a similar problem as it occured to Edgar. After a painful update of my iPhone to OS 4.0 none of my apps was installed on my phone. I tried to sync my iPhone via iTunes and everythng seemed to by right.

But at the end of the sync I was told that some of my apps (to be honest: not one) could not be installed because of "an unknown error ocurred: (0xE8003FFE)"

Even after reboot of my iPhone, an update of iTunes and a second try could not avoid this error.

I think that this is a severe problem, because I'm using some apps for my buiness.
I'm also looking for a solution for this problem. Is there anybody who can help?

Regards and thanks in advance

Same exact problem. None of my apps install.

I had a similar error message when trying to sync - unable to sync because a file is missing. When I deleted the iphoto cache from the iphoto library, everything worked fine. Maybe it's something similar?

sounds the same! My error code was 0xE8003FFE.

I'm also facing this issue on my iphone 3gs after updating to the OS4. Of which none of the customer support care personnel responded to my email which i sent twice after 2 days. I've tried all the options given on the more information page to which none helped the problem. Error 0xE8003FFE

I have exactly the same issue and get the same (0xE8003FFE) error number after updating to OS4 on my iPhone ... and it doesn't look like you can revert back to the previous system

I came across this thread that had a solution. It worked for me. Click on this link to go to the thread if you are looking for an error that says "unknown error occurred (0xE8003FFE)"

I simply had to unlock the restrictions for Installing Apps, and it loaded all the apps just fine. Hope this helps!

Sorry to be dim - how do you do that??

Here is the answer to the 0xE8003FFE Error. This is for all Iphones and Ipod Touches. Step by Step:

1. Go to Settings
2. Go to General
3. Go to Restrictions(4-digit passcode may be needed)
4. Turn on "Installing Apps"
5. Resync your Ipod and the Applications should be uploading to your Ipod.

Your welcome everyone.

if you have turned off the app store (or whatever the app is called) then turn it back on in settings (the restrictions page) and it should work fine. 🙂

Many thanks, I was about to lose all faith in Apple- it seemed to be a glitch and nothing I could do would fix it. My error message was 0xE8003FFE and I followed your step by step instructions in SETINGS and Im pleased to say IT WORKED! So you need to get more attention to your post somehow- I only found it by fluke by redirection by Google using the error code- lucky I scanned down to your post_ keep up the good work!

I can't get into General>restrictions. I need a 4 digit pass code? I did not set one and could use some advice as to what to do next. Thanks!
