[RAZR HD Q&A, Help & Troubleshooting] PantsDownJedi:
Sorry if this is a request for a lot of other threads out there but I can't find anything definitive, specifically since the release dates for JB are scattered by region and there's not always a clear answer to my situation because of that.

I have an XT925, the international RAZR HD. I got it recently her in Australia on the Telstra network with ICS preinstalled and with JB already released as an upgrade. I did save my root from ICS and still have root currently on Jelly Bean. It does, however, annoy me that I have to pull apart CWM packages, move all the files, and set permissions. In addition to that I've seen some talk about lag and people doing a factory reset to fix that. I have tremendous lag in folders in the default launcher and occasional noticeable lag in Nova launcer (which I prefer to use) window animations. My experience with Android has been with the Galaxy S II, which is still a great phone, however it is a phone that's easy as pie to root and deal with.

I have a lot of questions, some answered elsewhere but not necessarily in a context that applies to the situation I'm thinking of (and all the ins and outs would be too much to list), nor specifically for JB. Things get obscure given the

Please don't ask questions about why I'd want to unlock the bootloader, be rooted, etc. These are things I can decide for myself. Also, I'm aware I need to backup all my apps and app data to the SD card and pull the entire SD card contents. Please don't answer any of the questions unless you have first hand experience; I really would rather not get well intentioned misinformation that leads to a problem.

1. Can root survive a factory reset of JB. I presume it formats everything needed but still have to ask.

2. If the bootloader is unlocked, and I'm on JB, can I flash SuperSU by sideloading? If not, has anyone done it on a bootloader unlocked XT925 with CWM?; I've read some posts that involve a lot of confusion about the ease of installing CWM and using it on this phone. I should mention that I'm not familiar with TWRP and would like to stick to what's more familiar for the time being, assuming I go down this route.

3. Is there some advantage of TWRP over CWM? Honestly I don't even know what TWRP is; is this something I should learn since I have a Motorola phone? Also, is CWM well written for the device so far? Has anyone done a Nandroid backup and restore with it? Does it perserve time stamps (for OTA updates later given that system files have a 2010 timestamp on my device, for example)?

4. Has anyone had any of the more seemingly unlikely problems stated on the unlocking page of the Motorola site that you "may" have and for example, phone calls not working, apps not working anymore etc? Also, it specifically says "You will not be able to watch any movies you downloaded". Does this apply to videos purchased from google or does it mean that videos I've put on my phone will be unplayable? (I'm not even sure we can purchase Google movies from Australia).

5. There's a thread about disabling the unlocked bootloader warning, at boot, by replacing the file that provides the warning with one that does not, however I recall that the thread discussion was before the JB update (in my locale). Is this something that can still be disabled using the same tools in JB (assuming the original discussion was indeed for ICS)?

6. Does a factory reset wipe the system partition?.. specifically asking this because I've been keeping track of all files put to my system partition so that if there's another OTA at some point, it hopefully won't fail because I can remove everything added but if resetting wipes everything it would be easier to just do that.

7. Did anyone with an unlocked bootloader on ICS have a problem with the JB update, or more specifically if you had an unlocked bootloader on ICS, did it interefere with the OTA update to JB?

8. You know when you wake up to an alarm and have responsibilities but you'd rather just go back to sleep, but you get up anyway and it takes time before you accept the day ahead; doesn't that suck?

Any help here is appreciated.

It would be great if we had a master sticky FAQ thread for all the noob questions that one could conceive of. I hope that someone is able to write one.
