iOS 7.1 and iPhone 4/4s - corrupt system file or incapacitating passcode bug?

Anybody having issues with your iPhone 4/4s after iOS 7.1? If no, have you successfully enabled an alphanumeric passcode longer than four characters and been able to log back in after locking it?

Have been eagerly anticipating an iOS update, so when iOS 7.1 was made available it was downloaded and applied on the same night - admittedly a huge mistake; should have exercised caution and patience: the 4s device started rebooting repeatedly. Several times I was able to access the settings and been battling over a week with the device. Tried to restore the 4s in a variety of ways including erasing all content and settings, putting it in a recovery mode, and performing a backup from iTunes - the latter was attempted on two different machines just in case the original iOS 7.1 download was corrupted; however, that did not resolve the issues. Had also noticed that when [Wallpapers & Brightness] was pressed from [Settings] it was automatically triggering a reboot. The last time I was able to access the Settings, I had enabled an alphanumeric passcode. When it was time to unlock it the keyboard was partially rendered

Currently, every time I attempt to enter a passcode the device reboots before completing the proper entry of the code. Moreover, the backspace and the space automatically trigger a reboot. iTunes requires authorization from the device itself but since I can no longer log back in it is not accessible by it. Consequently, the device is unusable...

Btw. had updated my wife's iPhone 5 with iOS 7.1 enabling a 4-digit passcode (not an alphanumeric) - it worked OK.

Updates and resolution:

Had re-attempted a restoration of a 4s backup to an iPhone 4, thus the phone got updated to 7.1 but when it was done it was exhibiting the same reboot symptoms minus the passcode issues (after a restore that needs to be set up again). Attempted a reset by holding the Sleep/Wake and Home buttons for 10sec, then connected it to iTunes. The key difference: this time it was "Set Up as New iPhone". Then added a second keyboard and a alphanumeric passcode: tested it OK. After three days of light usage it has not crashed. At this point I am assuming the whole ordeal was due to a corruption propagated by image backups.

Q: does a backup image contain any system files?

Proceeded to reset my stubbornly uncooperative 4s, after several lengthy tries it got reset and also setup as a new iPhone. No apps have been added - it has been sitting idle for three days. There has been no crash but all the apps, accounts, configs etc have to be manually re-applied. Considering the previous issues reported as resolved.

No, unfortunately you'll have to go through a Restore but luckily you won't have to rebuild it from scratch:

Update your iTunes to the most up to date version, then connect it, you'll probably see the relevant message confirming that's in Recovery Mode, select the Restore in the Summary page, then it should give you an option to perform a Backup, perform the Restore, the phone should display a progress bar, when that is done select the most recent backup (it will let you know that that there's a more recent version available, if you select a different one), and then leave it running for as long as it takes -- it might take up all night...

In answer to my previous question regarding the presence of system files in the backup image - the answer is affirmative, a backup would have some system files but not ones related to an iOS update...
