OK, tell me if this is a pipe dream. I'm rooted and am pretty satisfied with the stock ROM plus bloat freezer to kill bloat. So starting with stock/root, if you simply do the OTA's as they are released here (and don't take them OTA), is it safe to just wipe cache and dalvik and then install the OTA as released here? Can you do that without a full factory reset? It would seem you should be able to: since you never have to factory reset when you take the actual OTA. Wasn't sure though.

It depends if htc made changes to framework and such you might have, after the rooted version is release they will some developers that will check and hopefully let us know we got some in the evo that you really didn't need to wipe at all
If you don't have an Evo3d well you don't have an Evo3d

A factory reset removes ANY data that is not 'pre-installed' by the rom.
Basically, its as if you just turned your phone on for the first time but instead of with the rom that came with the phone, it is with the rom you have installed.
You do not loose root because what actually is giving you root is code added to the kernel (hooks) and since the kernel is part of the system, it cannot be reverted to its original state, any changes made to the kernel will remain after a factory reset (Android at this time does not keep multiple backups of system files like Linux or Windows does - sometimes called shadow copies).
If your rom did NOT come with SuperUser pre-installed, you can simply redownload it from the market (if you were rooted).
One other thing, a factory reset also removes any cached data (davlik for example) as well. This is why it takes so long for the phone to boot after a factory reset or after installing a rom that does a wipe before installing (the phone has to rebuild the davlik cache when it reboots which takes some time).
If you are interested in specifically what a factory reset does and does not do, I recommend asking Google, its a very informative resource.
I'll just toss this out there; I got my phone a few days ago, and it was pretty sluggish on stock TW; adding ADW ex didn't help a lot, so I did a factory wipe reset yesterday, and it fixed things right up!
Did it to my wifes phone too, and it fixed a few little issues she was having too..I read some posts saying that it should almost be mandatory to do a factory wipe when you first get this phone, which i thought was weird, but, proved beneficial for both of our newly acquired Notes...
Absolutely, Android is alot like windows, it begins to just start performing badly. Typically, a simple reboot fixes things but one in awhile, a factory reset doesnt hurt.
So how do you do a factory reset????
Hello - I didn't like the updates I heard about in the factory 2.3.6 ROM update, so I skipped it. And, I'm rooted.
So, a few questions:
Can I upgrade directly from 2.3.4 to ICS from a rooted phone? Or do I need to step-up to 2.3.6 first?
Do I need to actually unroot before I do any of this?
Can I re-root once I go ICS?
I've heard that the best bet is to do a factory reset after upgrading to ICS. If I do this, is the best bet to do a Titanium Backup app & data backup/restore process? Are there any better solutions to capture all my data that I'd lose with a reset?
Any info/insights greatly appreciated. Note: I have searched far and wide on XDA for answers to these questions, but I could not find any direct answers that made me feel confident enough to move forward. So, any direct response appreciated.
Thx.

1. yes, you can upgrade straight from 2.3.4 I've done it.
2. you don't need to unroot before - the upgrade will unroot you.
3. your best bet is NOT TO FACTORY RESET AFTER UPGRADE - IT COULD BRICK YOU BECAUSE OF A KNOWN BUG IN FACTORY KERNEL
4. If you want rooted version of upgrade look for the odin.heimdall version the Creepyncrawly put in the development section.
or you could try Semi UCLE5 that i have linked in the signature. It looks like the stock upgrade but it is smoother, among other things.
Good luck!
Jon first of all, you can always upgrade to any new update regardless of your Android version so it's a Yes to your first question. Secondly, whenever you update to a stock ROM your device gets unrooted itself so you'll have to root it again.

Jack Man & uetfreak - thanks! Great feedback.
A couple follow-on questions for Jack Man:
I've read about the kernel bug, but THANK YOU for reminding me that it would affect a simple factory reset. Yeesh, that's a pretty serious bug when a standard reset could brick a phone. So, one remedy, as you say, is to go with UCLE5. Smoother sounds ideal to me (I've heard that ICS on GS2 is a bit jittery on the homescreens, which totally stinks). But if I go with OCLE5, that's a custom ROM so that means I'll lose the ability to do the OEM upgrade to keep all my apps & data intact, correct?
If that's correct, what's the best way to ensure all my settings, contacts, apps, data can be easily restored on a wiped phone? I have Titanium Backup + Root. I assume I'd keep root with OCLE5? And would I just run a TB restore on apps & data (and not system settings)? Are there any system settings I can backup/restore safely between ROMs/OS versions?
I've never flashed a custom ROM so I don't know how y'all keep all your stuff intact as you switch around!
Thx.

Well, first, since you have never flashed a custom rom I would suggest reading until you're sick of reading before flashing. It will pay off in the long run. Regarding flashing from 2.3.4 up to Custom UCLE5 and keeping all of your apps and contacts - I'm not sure how that would go, honestly. For me, my contacts and calendar are saved on my computer through MSOutlook and I sync them with MyPhoneExplorer without any problems. Most of the apps I use (which is not a lot at all) I don't bother backing up when I flash roms and wipe data clean. I have backed up some in the past with Titanium Backup (pro version is worth it), but only if I know absolutely that I need the data from them. Otherwise, I have just done fresh installs of apps because I have read so much about people having ROM issues from restoring apps with titanium.
About losing the ability to do the OEM upgrade - If you ever want to you can, it'll just take time, and yes, you would have to wipe data anyway to go back to 2.3.4 then use KIES. Kind of a pain if you ask me. Plus, ask anyone here on custom stuff - once you go with a custom ROM, you won't want to go back to stock - EVER.
Hope this helps. feel free to pm me if you need. I'll be on the road for the next few days. remember - READ as much as you can. start with the "stickies" in the top of the main thread with a little pin on the left.
p.s. one more thing. Get yourself a usb jig. it's only a few buck online. once you start flashing roms you may want to try other ones. If you make a mistake somewhere, a jig can get you out of a jam quick.
Make sure to factory reset after. Ive read many problems with notifications messing up until the reset was done. I've done it no problems. On two seperate s2 i777s. Its always best to do this after a big update to the next version

Good idea. I do resets if I come from gingerbread too. But I know with this ROM (http://forum.xda-developers.com/showthread.php?t=1650948) you have to make sure you have the kernel that is based off of the stock kernel - AJ's kernel to safely factory reset. I think you will get a boot loop if you factory reset with the Siyah installed. I could be wrong, but I remember getting a boot loop on mine when I had siyah installed. Maybe it was because i did a reset from settings/back up and reset/factory reset and then formatted the sd card (since I had so much useless crap on there, luckily backed up on my pc).

You're kidding right? No do not tell him to factory reset with the stock kernel. If his phone has the big he could burn out his emmc chip. Then he would need to pay mobile tech videos to jtag it.
Sent from my Sony Xperia Ion
you have to flash iOS on your phone first before you can upgrade to cupcake, immediately update to donut before rebooting, then you have to go through eclair, froyo, and you will find yourself at gingerbread. DO NOT REBOOT AFTER FLASHING GINGERBREAD!! you have to flash ICS during the shutdown process....if you miss your cue, you will have to start all over
Just the other day I had a weird thing happen. I rebooted my phone and when booting I saw Android is updating, followed by optimizing apps and starting apps. I had not run any update of any kind at all. The phone booted fine and ran fine afterwards. Now everytime I reboot the phone, I get the same message Android is updating then it says starting apps and then the phone boots up as normal. Anyone know why this is happening? Is this a problem? I had a similar thing happen on my tablet and when I ran a firmware update afterwards then started getting all kinds of errors.
If this is a problem how do I fix it? And with this happening should I not run any updates?
I am rooted and on stock firmware with no updates installed.
Thanks in advance everyone!
This happens when cache is cleared, anytime you flash a ROM or kernel you are supposed to wipe cache and most packages will do this for you. Your tablet doing this after a firmware upgrade is normal, the errors weren't.
Now if your phone is doing it every reebot it probably means one of two things: 1 your system is wiping cache every shutdown for some reason or 2 your cache partition is corrupted.
If you are unrooted I recommend talking to Verizon (or whomever you purchased it from) about warranty, if its rooted I would try wiping cache and dalvik cache through your recovery (this will cause it to happen one more time but might prevent a second or third) and see if it keeps doing it after three reebots. If that doesn't work wipe everything (cache, dalvik cache, and user data) and reflash your ROM or another ROM. If that doesn't do it either unroot and talk to Verizon about warranty (after resetting the flash counter)

What's the right way to wipe the cache and dalvik then? Should I use titanium backup? Not sure how to do it from recovery on this phone. And will doing this have any side effects?
Thanks again
Also, I haven't flashed any roms or new kernels.
Please, any and all responses and ideas. Im sure the last person that replied knows what he/she is talking about but I just need a lil more info...
Thanks again all!

Depending on the release, MDk, ME7, MI1, MJ7 you may not be able to wipe the cache manually from the recovery menu.
Whn I was on ME7, no problem. Now that I'm on MI1, I can't do a manual wipe.
Hi. I bought a near-mint S4 on Swappa from a seller who had already rooted it and installed a custom ROM (one similar to Samsung stock). After verifying that it worked I did a factory wipe, deleted the caches and used the existing TW recovery to install CM11, which so far I just love -- it's extremely close to the stock Android on my Nexus tablet, only with other great options like running Titanium backup and a firewall, etc. The lack of VZW and Samsung bloat is also great, of course.
However, do I need to worry that the phone could still be infected with or vulnerable to malware, perhaps because of something left over from whatever process the seller used to root the phone and install recovery? Would using the Avast firewall protect me, or would I be wiser to unroot the phone, take it back to stock and start all over again? (I'm reluctant to do that because it has the MK2 baseband and I'm afraid of not being able to get back to having a custom recovery.) Am I worrying needlessly, because the willing and installation of CM would have deleted any dangerous stuff that may have been lurking?)
This is my first time dealing with a rooted phone or a custom ROM. I really like the idea of having more control over what I run on my own phone (similar to running Linux on my computers, which I've been doing for years), but want to make sure I'm not being foolish somehow.

Since you're able to run CM11, it must be running the MDK build, which is pretty amazing as you can run what you want with the Loki exploit allowing you to bypass the locked bootloader.
If you really are concerned about what's on the phone, you can always flash a full-wipe factory MDK ROM image and start over.
DO NOT - Don't - no - never- take any factory updates. Or flash anything past MDK from Verizon. Ever.
Thank you -- I do indeed feel fortunate about having the MDK build and don't want to do anything to mess it up.
How reasonable are my concerns about some vulnerability being left on the phone by the prior owner? I did two wipes of the phone (system, data, cache and dalvik cache each time) before installing CM.

You'll be fine if you hop into recovery and do a Factory Reset where it includes the Internal Card.
Most likely your all set though with what you've done. Enjoy that MDK phone! I also have one and being able to run non Touchwiz Roms is the only way to go if you ask me.
If you have anymore questions regarding MDK feel free to hit me up or ask here... Were all here to help

I've downloaded the update, but now I decided not to install it due to several issues that it will cause. Most importantly breaking my call recording capability. How do I delete the downloaded update, or at least get rid of the notification - without rooting the phone?
thanks!
I guess a factory reset would do it, but maybe you can try just wiping the cache in recovery? On some phones the updates at least used to be stored there, but not sure.

Factory reset is not an option. Will wiping the cache in recovery affect any applications installed?
I know where the update is downloaded into but I cannot delete it without root access. And I rather avoid rooting my phone at this point.
