Flashing new ROM - wipe or restore - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Surely this question has been asked dozens of times, but given the brickbug I'm not sure if there's a better way for our skyrockets.
I'd like to try out the new Chimera, coming from SkyICS. Would it be best to format everything and do factory reset, inside CWM or to restore my backup right after originally flashing CWM with stock 2.3.6?
Thanks

Went with the restore, no problems. I'm oblivious as to how to wipe the actual data which includes all the prior apps. Wipe Data/Factory reset didn't work. Do I need to just format SDCard in CWM to get rid of everything? Or is the main mount the /emmc?
Only thing I found with looking around was just deleting everything while mounting to PC. Went with that but it only deleted about 700mb. I know I had a couple games installed that took up ~1.5gb total, so I must assume 1 was deleted at some other point.

Skyrocket stuck on startup after flashing rom

I just flashed the MXH Superlite rom (http://forum.xda-developers.com/showthread.php?t=1525638&page=43) as per the instructions onto my skyrocket i727. Wiped it, cleared dalvik cache and formatted the system. Installed the recommended modem followed by the rom, and the phone was stuck on the Samsung startup screen. I've recovered using a backup, but I really want to install this rom. Whats the problem here?
Try booting into cwm and re wipe and reinstall, try just the rom this time

Your best bet is review the MHX-SUPERLITE thread in the Development section... and ask there. This rom is on my "next to flash" list as well...
I flashed it on a friends sr no issues but it progressively got slower and crawled after first reboot it was odd.

You need to wipe everything a couple times before flashing on these phones and sometimes install 2-3 times too
Wipe data, cache partition, and delvik 3x's each and install twice or something

[Q] Failed encryption, what do I do now?

Hello,
I inturrepted encryption process and now regardless what I do I can not put any ICS ROM on a phone.
I flashed back to stock with Odin and Gingerbread works fine.
If I flash ICS then it loads with "Encryption failed", please reset device, resetting device does not help, it just loops again with the same error message.
What do I need to wipe for phone to forget that it had failed encryption at some point?
In all likelihood you will need to download a stock tar and use Odin to get everything back to normal. can you boot into recovery? I has this issue with my NS4G and ended up being able to get back into cwm and ended up reformatting each mount point. after that I was able to flash another ROM but sadly all of my data was lost (I trust that you made a NANDroid backup, right?)

Odin back to stock, wipe everything, format system etc did not help. Format sd card did not help either. I have full access to everything, download mode, cwm etc. There is no problem with phone at all while on Gingerbread, but anytime I try to install any flavor of ICS I immeditially brought to this error message about failed encryption. What else I need to wipe for it to forget about failed encryption?
Did you try darkside super wipe?

i dunno man, I'm out of ideas. Hope you figure out. Never tried encrypting anything. Glad i didn't.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
Please let us know if you figure this out. I am having the same issue and would like to find my way back to ICS somehow.
My guess is that an encryption key is being stored into one of the other partitions, like efs1, efs2, params.lfs, etc. These partitions aren't accessible from cwm or dark side wipe, which is why wiping cache or data doesn't fix it.
Will need to look more into how ics encryption is implemented and see what we can do.
It's probably a stupid question, but why would you bother to encrypt the data on your phone?

IF a user uses the phone for work e-mails, it is most likely a policy to enforce data encryption.
example, using mobileiron app with ICS forces encryption.
Encryption is a must nowadays. I did the following:
1) Go to Fastboot and flash stock Samsung. I used a JIG for that
2) Go to stock recovery and do a factory reset
3) Load the android and format internal sdcard from notifications menu

You realize a factory reset in CWM wipes the data and cache right? After that you just proceed to install the rom, why do you need a zip?

Using the "date wipe/factory reset" option wipes everything in /data (this includes dalvik cache) and /cache. Then when you flash a Rom it will format /boot and /system.
I'm just trying to understand why there needs to be a zip for it or what benefits that would possibly have? I can use recovery and wipe data/factory reset with 2 finger touches on my phone, and then use a few more (depending on where you store your rom zips) to install the rom of my choice that will format /boot and /system. Even if you use a zip to wipe, you'll still have to install a rom, and it sounds like the zip method would require more actions.
I'm not trying to be a ****, just trying to understand because i've never used a zip to do my wiping. It was never taken off topic by me.

Yes, do that again. Boot into Download mode(Batt pull to turn the phone off) then hold vol down+home+power till the prompt comes up.

I can just flash 66 as is? Don't have to flash a stock unrooted version first like you do when you brick?
Do you have any idea why this could have happened? I did everything it said on the page and even watched an installation video for the ROM following every step by step instruction. What the hell does formatting system, data, and cache do in recovery? Never had done it before and as soon as I did my phone just messed up. Also, if I flash 66 using odin will my old backups work again?

I'm guessing there was a bad download and sadly your nandroid might have been corrupted.

Cool thanks. Flashing 66 now through odin. My backups have worked fine before (the exact same ones that just failed). Once this is finished and I test out my backups (assuming they work) how should I go about reflashing JellyWiz? Should I format the system, data, cache again or just do the normal wipes? I'm afraid formatting will mess it up again. Is CWM inferior to TWRP? Thinking about using a different recovery after all of this.

I personally use cwm and to me it's more a matter of preference. I too have had a error restoring backups once and it was after a system wipe. A word of advice, because this saved me, keep a ROM on your SD card at all times to be able to just flash in an emergency.

I think you missed my point, at this point he needs Odin. However, if you keep a zip on your SD card then if your backups gasp like his situation he can just fish that zip. It was simply some advice for future reference, were not all next to a computer ask the time. For people like me that just get an urge to flash it helps to have backups like this.

in order to flash jellywiz i had to do the following or else i bootlooped:
wipe data/factory reset
wipe dalvik cache
format system
flash rom
booted up flawless.
i also used this methid for paranoid android...i will probably update my guide with this. unfortunately i cant give any info on what formatting system is actually doing. never had to do this before??

I don't know why they are suggesting it but it doesn't do anything beyond the normal factory reset and then the zip formatting system itself.
Its just the manual way of doing what a clean flash does.
Why are people having issues restoring nandroids after doing this? Apparently bootlooping occurs after format/jb install/restore previous nandroid.

if im not mistaken formatting the system deletes the rom/kernel itself...normal factory reset from cwm recovery only deletes rom data/cache.

i wonder why i had to format system to get the latest jellywiz rom to not hang on galaxy s splash screen? it makes no sense.
Also, how does a format not erase your nandroids? It should also wipe titanium backups if they are not on your external. Am I wrong on that? Could formatting lose certain bits of info that the nandroid may not have partitioned, and that's why the restores are not working correctly?

Restoring a nandroid backup

I am currently on CWM touch recovery v14.4.6. If I want to a restore a nandroid backup, do I perform the following steps before I hit the restore button?
1. wipe data/factory reset
2. wipe cache partition
Any guidance is greatly appreciated.

Yeah it's the same. So I should have said I format system/data/cache. Do those and you'll be fine.
Just remember that you have to flash the radio separate if you need to change radios. Nandroids to not contain the radio / modem. If you want to keep the same radio / modem, then you won't have to do anything except flash the nandroid.
I have problems restoring lately. I use sk8ers cwm latest and when restoring I get system could not be restored. I did backup pre load. I use the externel SD card to backup. Md5 sum checks out fine or appears to check out fine.
Normally I wipe just as if I was installing a fresh rom before restore. I have restored backups without wiping and they work fine. Just gives me piece of mind especially if I encounter any issues.

Have you resolved the issues? I got error messages when I tried to do a nandroid backup with preload option checked. So, I decided to do a normal nandroid leaving out the preload and got no errors. I haven't tried to do a restore yet afraid that I might have the same issues as you.
I do believe that my backups got corrupted maybe from just not unmounting from pc properly as I just un plug it most the time. I lost the backups but still got titanium so no big loss. I change roms like I do underwear.
