Why does my Galaxy S4 crash after the Lollipop update and is stuck in a bootloop?

galaxy s4 crashed after lollipop and in a bootloop

I have a galaxy s4 and here is the issue:

after 1 to 2 weeks from using lollipop OS all the mobile applications started crashing continuously and that usually used to end up with the GUI crashing and not working any more ... and the mobile wasn't always booting up and if it did .. it wont take so long until the the whole GUI stops working again.

When I tried to update the SW it suddenly displayed this msg "the OS on your device has been modified in an unauthorized way. try downloading software updates using Samsung Kies on your PC, or visit a customer service center." plus the status was a custom and not official.

I haven't done anything with my mobile and I've been using it since 2 years and everything was normal, these crashes ended up with the mobile stuck in a Boot-loop

I've tried to: wipe cache, emptying the capacitors, factory reset .. and nothing worked

I also don't think its an issue with the power button because, when ever I put the battery it doesn't turn on automatically. I have to to press the power button by myself

Please, does anyone know what should I do ?

Re: galaxy s4 crashed after lollipop and in a bootloop

If you're in the US, bring it to a Best Buy and look for the Samsung rep in the cellphone area. Explain what happened (that the Custom status appeared due to the update failing, not due to your doing anything) and ask if they can reflash the update or, at worst, reflash the entire rOM (you'll lose anything you don't have backed up).

I believe Samsung does something similar in the UK with a different chain of stores.

In other places, contact Samsung.

(If you're in the US, and have AT&T as your carrier, you cn also try their Device Support Center - your local store can tell you where the nearest one is. They can also flash ROMs and updates.)
