Hello everybody. I need some clearance. My final goal in the Scheme of things is to Back up all my data, install the newest version of Cyanogen Mod, Restore Cyanogen so that i get all my apps and data back, and then eventually restore everything to stock so I can trade in he phone, and then repeat the process with a new phone. Can anybody tell me some of the first things I should do, to nudge me in the right direction?

Also, read more. Some of the things you want to do can't be done in the order you want, and restoring a Nandroid from a different device is a great way to brick.

It's also not a good idea to restore app data (via something like Titanium Backup) between different ROMs.
There's an app called. Scandisk that will b/u your internal sd to your ext sd. User data only I believe.

You can also just plug it into a computer and copy it off to your hard drive.
But to the OP, I would heed the warnings about restoring a nandroid backup on a different phone.
I'm not sure I follow the logic of installing a custom ROM only to restore to stock and trade the device in.

I think the OP wants to get a ROM running on their current phone then Nandroid it and restore the Nandroid on a different phone. Even on the exact same model of phones, restoring a different phone's Nandroid is an excellent way to get yourself a very expensive paperweight.
To clarify my logic, i wanted to turn in my phone in about a year, so I have a year to mess around on Cyanogen Mod, then when my phone contract expires down the way, upgrade my phone.

Use Google and tibu and you should have everything backed up while you play around with your phone. heed the advice on not updating app data, apps are ok, with Tibu.

What provider are you with? I don't know of any that make you trade in old phones.
That said, I would definitely not try restoring a nandroid from one phone to another, even if it's the same model.
Even restoring data from a Titanium Backup would be dicey. The best I'd do would be to restore apps only (or better yet, just download them again on the new phone). It doesn't take that long to set things back up on a new phone.
Restoring Nandroid from one phone to another of the same model is fine. It works on Android phones since the beginning of time, as long as the backup includes only /system, /boot and /data. In that case it's also a non-damaging action, since on Skyrocket, like on HTC phones, there is no Samsung weirdness of holding a recovery in the kernel, but recovery is a separate partition - and you can still boot to recovery, even if you restored a corrupted backup, so no need even for Odin.
I don't restore system data from Tibu period, even if it's just dumping it right back onto the same ROM. I've had too many problems in the past with it corrupting something or another, or causing countless FC's that fixing permissions doesn't solve, requiring a clean wipe and reflash.
I've never had a problem flashing app data, just so long as you go through the list of apps carefully and make sure that absolutely nothing system or stock (including stock email, calendar, browser, etc) is being saved. Restore user apps and user app data ONLY with Tibu and you're pretty safe.
I'm with AT&T. By trade in, I ment selling it back to AT&T for some cash value back. And I can be mistaken, but don't they also place your old sim card into your new phone?

So you've got a year to read up and learn how to not brick your phone doing it, then? There are stickies at the top of each forum. Combined, they explain how to do about 95-97% of what the typical XDA user will do with their Skyrocket. Before you can do what you want to do, you have to understand why parts of it are impossible to do in the order you want to do them, and why other parts are risky to the point that you might, if you're not careful, screw up any chance of resale.
Thanks TJ. I'll take you up on that.

Okay I am staring this thread because there are mixed answers in the official update thread and this might give one spot for noobs like me that are not flash addicts a place to find the quick answer.
Here is my setup:I am rooted, running a bone stock JH7 rom, ROM Manager installed, Circle Battery Mod installed, other than that no custom kernels, modems, radios, etc. I do have a couple programs that require root access like ROM Manager, AdFree, and ClockSync. Already installed kies mini and have it all set up per the instructions on samsung's website. Just waiting for the update to go live.
Here are my questions:
1) Do I need to unroot?
2) Do I or should I uninstall any apps that require root access or change the recovery image (ROM Manager/Clockwork Recovery)
3) Should I remove both my external SD and my SIM prior to flashing?
4) What data will I lose and how do I back it up? (I have read that SD cards are left alone just system data like call logs, sms, contacts, email setup, saved passwords are lost) I have Lookout installed so I know my contacts are backed up.
5) Could someone way smarter than me please do a quick write up that is more detailed on the steps needed to complete this update AND keep all your data? I don't mind reinstalling apps (just hope I don't lose all of my angry birds progress )
All of these questions are not address in any of the "official" information other than "you should back up any data you don't want to lose" but gives no steps on how to do it.
Same question here, I'm rooted with TiBU and voodoo lagfix and that's it., well besides deleting all bloatware. Still on eclair jh7. Wish I had done lagfix months ago, but I don't have a computer.
Hey guys, what's this button d....

If you have a modded phone the smart thing would be to wait at least a few days before installing the update in case the rollout doesn't go as planned. These are the kind of things AT$T has probably been dreading as far as Froyo is concerned because I'm sure that come tomorrow their customer service lines are gonna be blazing like a CA wildfire due to issues with not completely stock phones and thousands of different configurations causing update glitches. I wouldn't be in such a hurry to update until I see how it goes for the "gotta have it now" sheep taking the first plunge.

Remember OCLF is bad, Mmmkay? Better lagfixes such as Voodoo and ULF
All lag fix should be removed. Otherwise, you will very likely end up with a bricked phone.
You can install Kies Mini now and connect your phone. If your phone is recognized without problem, you're good to go. Kies Mini is your only way to update the firmware.
I can't answer most of your questions, but I will recommend getting Titanium Backup. You can at least backup your app data since you're so concerned about your Angry Birds score. I think you can probably restore that after flash.

Did you copy the TiBU folder to your PC after doing a batch backup of your apps? That's the only way to reliably save a backup.

Not to be a negative Nancy, I understand some want to stay as close as possible to stock, but I'd just wait for a custom ROM to be built that de-bloats, adds speed, better GPS, etc... Cog 4 has a really stock look, and works really well; check it out. And with time there will only be others that will improve on the great ROM's we already have!

The other smart thing to do would be locate the TiBu backup folder on the external SD card. That way even a brick requiring reformatting the internal sdcard partition can be fully recovered from. Just take out the external card while restoring to stock, then root, get TiBu, point it to the reinserted external sd card, and boom, back in business.

You should use OCLF app to remove the lag fix. Don't do factory reset or flash another ROM. You may brick your phone that way. That's why I don't use any lagfix.

Yes You should be a bone stock when updating. No lagfixes, custom kernel, nothing.
All questions for the 2.2 update are in the main thread
I was just thinking everyone is bummed about not having a full working cwm to do a full restore. But when u screw up its Odin to the call. right? I just don't see why we need full CWM when we can use Odin if we mess up. As far as getting things back to normal (setting,icons,wallpapers,etc.) U can use advanced restore to put everything back the way it was before the flash but still keep the effects of new kernels and roms. So i ask this why all the fuss? Also maybe someone could elaborate on the mount issue. Is it only when you try to do a full restore Or flash certain Roms? Oh yea and this is a noob asking.

It's mostly a question of convenience. If we get a fully functioning cwm it can be directly booted in to replacing the stock recovery. More importantly it can be incorporated into Rom Manager which makes lots of things easier and more standardized. Things like flashing roms and kernels or restoring backups and making fixes would be much easier and all right there in rom manager/cwm.
As far as Odin/heimdal goes yes that works for installing roms, restoring from soft bricks, etc. but is no substitute for a nandroid backup/restore which is great for reverting to a former configurations fully and easily after trying out new roms, kernels, etc.
There are other reasons it would be great to have a finished cwm but what we have now is not that bad since it can do most of the important things we need.
I am still interested in what I hear that people are restoring full nandroid backups successfully. The official word is that its not unmounting properly during format function in a restore, at least that's what I understand. If full restore is actually working as some are claiming then I'm not sure what is actually left undone.

Advanced restore lets you restore just not full restore. It gives you the option to restore system,data,ect one at a time. However I have not tried to restore system just data. Like I said before couldn't full restore due to mounting issue. Also I think nandroid backup is just another term for a full backup of basicly the exact state of the phone at the time back up is done. If I'm wrong please feel free to correct me.
Sent from my SGH-T959V using XDA Premium App
Ah so it sounds like there is still a mounting related error after all. And yes you got it about right. A full nandroid restore basically brings your phone back to 100% exactly the state it was in when you backed it up.

As I posted on the Wiki, I have successfully done a Nandroid backup and a Nandroid restore... In both cases the "system" was identified as being backed up (or restored).
I have repeated this several times, the most recent being this morning. But, in an effort to not dispute krylon360, I've posted a targeted question to him in his thread announcing CWM3.0.2.8Beta.
I am hopeful of his response!

restore definitely works on cwm.... u all r kinda being wild... there are already threads on this... look at the development thread for clockworkmod... comparing odin to cwm psshhh
Nothing wrong with odin. Nothing wrong with cwm. I have been backing up and restoring with cwm for a while now. Still don't know if it's a true "nandroid" backup but it restores everything but my lock screen wallpaper. Everytime without fail. So good that I have not had to use odin or titanium. I'm even sure I could odin at this point and get all of it back through cwm. Follow the steps for setting it up you should be fine. I'm running whites KD1 and have been since it came out.(**** I might have to Odin now just to check it out) How do you use Odin again?
Have fun
Does back up recover everything. Like a clock work recovery. New phone with old SIM and old memory card. What will restore? Will give me back all my apps or is that on the USB of old phone? Can I even use clock work with new phone? Or must it be unlocked?

When I have done a nandroid restore I usually get all the apps that were there when I backed it up. It also saves the user settings for the apps and anything the way you customized it (like wallpaper, widgets, launcher, etc.). It doesn't affect internal or external sd card.
You need to have CWM in the first place to restore the backup though. And I don't know about using a backup from another phone...especially if its not the same model.
In order to restore you must first root, have CWM, and make a nandroid backup. You can't restore anything until you have a backup to restore from.
U CANNOT restore a nandroif backul from a completely different phone to a new one, unless they are the same model (eg skyrocket to skyrocket)

I just got a warrantied out replacement phone and want to restore a previously saved nandroid backup.

To play it safe, you may be better off installing everything from scratch. jiggity janx said this on the SGS3 "I thought I read somewhere recently that because backups capture phone specific data on Samsung models that you are unable to move a backup from one phone to another without overwriting some valuable individual phone information". Besides, the location of the folder would make a difference also.

Basically you can't. The best way to do 'clean up' would be to run an RUU and format the sd card (backing up important files first). Yes, running an RUU causes you to lose root, but contrary to popular belief root isn't the most important factor. Your unlocked bootloader (which is far more important) survives the RUU process, which means all you do afterwards is flash TWRP and flash root (or a rooted ROM), and voila.

The first thing you want to do is backup anything that's on your sd card that's important to you. Just mount it to your PC and copy important files across. Next is the RUU, but you'll need s-off for this so if you don't already have it, get it now. If you have s-off just download the 3.18 RUU, connect your phone in fastboot mode, and run the RUU exe program in Windows, simple as that. You just need to make sure no other programs are running, make sure HTC Sync Manager is uninstalled (leave drivers installed though), and make sure screen saver/hibernation is turned off. Once the RUU is complete it's just a matter of flashing TWRP recovery again, if you need directions for that just click the How-To Guide For Beginners link in my signature.

You haven't really been clear on what you want. Do yourself and all of us a favor, and just slow down and explain it in a thorough and specific manner, not just 1-2 sentence responses.
A couple different approaches to clean things up:
1) Do you just want to clear up some space in SD storage? Then yes, if you have multiple TWRP backups on the phone, just move them to your computer. You really only need one nandroid on the SD (recent and known good configuration).
There are a lot of other files that can take up a lot of space and potentially be cleaned up "manually". Some examples are ROM zip files (don't need them after you have flashed the ROM), pics and videos, etc. Just copy whatever you want to keep to your computer, and delete them from the SD.
2)

I'm not sure you know what "factory reset' actually means. Its a bit of a misnomer. All it does is wipe the user data (/data) partition. The current ROM is retained, as is root, bootloader unlock, etc. It also does not touch the "virtual" SD (including your nandroids), although you should back them up to your computer beforehand anyway, just to be safe.
If you want to wipe the phone, but keep the ROM, then a factory reset is exactly what you want (then re-setup the phone, apps, etc.). One approach might be to backup any personal data (nandroid, Titanium backup files, photos) to your computer, then use TWRP to wipe the SD and factory reset, then move your files back to your SD and setup the phone again as you like.
Whatever you do, don't factory reset in bootloader, as a known bug on modded phones means that this will corrupt the SD. So you will not only lose any data on the SD, but also have to reformat it in order to fix the corruption.
