Wow, you could actually lose the data with this bug. Glad it was fixed in 12.3. I remember the last time something like this happened (4-5 years ago?) it would only crash the phone.

The problem isn’t that the bug itself will cause data loss - it’s that you have no way of using the phone because of the boot loop unless you wipe. I’m not entirely sure how you’d go about updating the phone without booting into it, but I think it is possible, and that would be one way to avoid losing all your data due to the bug.

  One of the comments on the bug has the answer: For testing purposes, there are three ways that I found to unbrick the device: 1) wipe the device with 'Find my iPhone' 2) put the device in recovery mode and update via iTunes (note that this will force an update to the latest version) 3) remove the SIM card and go out of Wifi range and wipe the device in the menu

    Instead of wiping the phone, couldn’t you just disable iMessage once you habe removed the SIM card and are out of WiFi range?

      Would that mean you could not use iMessage any more (without the patch)? An iPhone without iMessage is significantly redundant, at least in N.America.

You only lose data if you’re not backing up your phone - it’s not a corruption bug that breaks the ability to restore backups (like one of the iOS iOS 11 developer betas did).

  That's like saying that with a faulty hard drive you can only lose data if you're not backing it up.

    Well that’s not wrong.

    Close, but imprecise. I’m saying two things: You can lose data with a faulty hard drive if your backup is silently corrupted and you don’t realize it. That’s not a risk here, as long as before restoring from backup you upgrade the phone OS to patch the bug. Also, you can lose data with a faulty hard drive if you have no backup. Rooters especially will care about these points since they typically cannot restore from backups without upgrading the phone away from a rooted version, due to choices made by Apple in firmware.

      Actually, if an iCloud erase works, it should be possible for Jailbreakers to recover their phones without updating. Mind, they will still loose data, including some Jailbreak stuff that isn't included in iTunes backups.

  You can still lose data because you can't really back up the whole phone with standard tools.
