How to upgrade from CM7 RC3 to final release?

I saw that the final release of cm7 came out and I'm super excited for it! I've been running RC3 for awhile and it's been working fine, but there have been some issues that I would like to have fixed with the update.
My question is: Is there a way to update the rom without losing all of my data or having to do a full wipe?
Any help is appreciated. Thanks!

You wont need to do a full wipe, just download the ROM to your sd card, boot in to recovery and do a nandroid backup. Then select wipe cache. Once that has finished head to advanced and select wipe dalvik cache (some people say to do this some don't, I do) then flash the ROM.
You will only lose all your apps and setting if you select wipe data, you only need to do this if you are have serious issues that cant be fixed by any other means. Or if you changing to a completely different ROM.
And remember to do a nandroid before touching anything else in the recovery menu

That's it? Awesome! I know what I'll be doing tonight.

Or you can just do it from rom manager and not check the wipe data. I swear some of you just like taking the long way.
Always do a nandroid?No. Nandroid your original rom? YES. Nandroid custom rom? Only if you like it..but to do a nandroid every single time you flash new rom is ****

ROM Manager can some time cause issues when you flash directly from the app, Some people prefer to do it manually. Ok it might not be totally necessary to wipe the cache's between flashes but does really hurt?
And I resent you saying that doing a nandroid is "F'in Retarded" how frequently do we see people on these forums who have flashed something there not supposed and there most recent backup was weeks ago. It never hurts to do a nandroid it adds 5 minutes to the total time it takes flash something.
As some one who does do a nandroid every time I take your insult personally. And that sort of language is not appropriate in a forum where people of all ages can view.

LOL i don't even have a nandroid of my original ROM. I just got 1 image of RC4...

So I wanted to be 'better off safe than sorry', and I did a nandroid backup (using the latest CWM) before doing a CM7 RC3 -> CM7 Final non-full data wipe upgrade. I had a bunch of problems from the get go, and wanted to revert back to my RC3 backup as I didn't have time to fiddle with everything to get it tweaked from scratch...
However I can't for the life of me get Clockwork to recover my backup. It stops half way through and I'm left sitting at the main orange menu with no confirmation or details on what happened.
Any thoughts?

Glad its not just be with this mentality. Better to be safe than sorry. I haven't had to start from scratch since the first nightly, because I all ways have a recent nandroid, some times things do go wrong.

I did the backup (2 actually) and just installed the update. Everything seems totally fine so far and I'm really happy with it! Seriously stepping up to cm7 has made my G2 go from a decent phone with a nice keyboard to a flipping fantastic phone!
Many thanks!

Your definition of *** seems to be basically the opposite of mine. What if an update breaks something (especially if you are cutting corners by not wiping or by using ROM manager) if you don't have a nandroid of your phone before you flashed that update you are screwed, you will need to start over from scratch.

Yeah, I agree with you completely. Doing a nandroid takes 5 minutes. Then later you can just move it to your desktop computer, to not take up space on your SD card. I have 3 TB of storage on my desktop, so no worries about saving as many nandroid backups as I feel like.
I've seen random issues pop up on my phone for no obvious reason, with no clear fix. But reverting to a nandroid cleared it up.
Really no reason NOT to do it.

From Gingerbread to ICS

Hello!
On my Samsung Touch I still have EG31 Rom Rooted and with Rogue CWM. Is it possible to install FD02 Rom and more important question if this is possible what is the better way to do it and how can I save all data? I mean, what is the better way to do it?
Thank you!
Please, help me?

I'd highly recommend some reading -- first http://forum.xda-developers.com/showthread.php?t=1525495, then a few threads over in the development sub-forum about the ICS leaks. You are much better off not trying to save data when coming from GB.
You have a couple of ways to go to get started with ICS on the E4GT. You can use one of sfhub's one-click ODIN solutions (see his sticky at the top of the dev section, and http://forum.xda-developers.com/showthread.php?t=1584151).
Alternatively, you can find and download a) a copy of Calkulin's format-all flashable zip, b) an FD02 flashable ROM (I recommend agat63's or calkulin's as good starting points, but there are many options.) and c) the FD02 modem. Boot into your current recovery, make a nandroid backup, then flash the format-all zip (which will wipe everything), then the modem and ROM. Reboot, and you should be on FD02.
I *highly* recommend you take the time to read through the threads of the various ICS leak based ROMs out there -- at least enough that you know what the OP is talking about with everything they say. It will be time very well spent.
Finally -- this is just my advice and in no way implies any sort of guarantee... you are responsible for what you do with/to your phone.

So, you are saying I can't even use Titanium Backup for restoring data when I'll move from GB to ICS?
Or there is the way? I'm asking about it because I have more than hundred apps right now and it is kind of annoing to install all of them from scratch. And also kind of annoying to type all of the data again.
If there is the way, please, help me with the advice?

TB _apps_ restore should be ok. TB apps+data restore might be dicey (tho tbh I got away with it on a few apps... others behaved pretty badly... lots of fc's and other bad behaviors.) Best advice -- read, read, read, then back up, make the leap, make another backup on the ICS side, then see what you can get away with restoring apps bit by bit in TB.

Not really a good idea to TB anything GB into ICS. Greatly raises the chances of issues period. The store now has a page that has all the apps you have downloaded, makes it alittle easier. You can also make a copy of all your apps and put them on your SD so you don't have to redownload them again. IMO, a clean install is best.

Ya like bigtoysrock said don't even restore just the apps. It is highly suggested you do a fresh install of everything.

After moving to ICS, is it ok to use TB to back up apps and restore them on another ICS rom?

You pick the right ICS roms like CM9, Codename, Gummy, AOSP based roms, etc...and they will get backed up to Google for you. You are asked not to restore with TB to save yourself on what could be a potential problem. I can honestly say I have restored some of my apps with TB and have not had any issues from GB to ICS. I can also say that I have had issues in the past and if you mess something up this way its a pain the arse to have to start over.
But like also recommended in here I believe a clean install is the best thing to do and honestly its the best way to troubleshoot any issues.

When I first went to an ICS ROM from GB, I did use TB and didn't have any issues. I eventually did a clean install for an update and reinstalled all my apps through the Play Store.

For your first flash from GB to ICS I would do a clean install not using Titanium Backup. Reason being is ive had some odd bugs when I have done this in the past. On the first flash do it the long way and reinstall all of your apps manually. After you do this then backup using TB and as a safe measure I would Nandroid backup as well. Any updates after that you can get away without doing a full wipe in most cases. If you have any bugs and you are sure you did everything correct do a full wipe and install and see if the problem continues.

N00B question: Hate new ICS need to go back to GB

A friend created a nandroid and Titanium backup for me, and my phone is rooted. I'm currently on ICS and I want to go back to GB, Do I have to Restore Epic 4G Touch With Pre-Rooted Stock Gingerbread Firmware — EL29? or can I just use nandroid recovery since it's like a full system image right?
So confused. Want to go back to old GB without losing apps or settings. Please help?

You can restore the nandroid from a safe recovery like EL26.

Yes that helps. If you don't like ICS (FF18) ODIN back to EL29 (Gingerbread). thats the safest way or to keep what you had under your backup; ODIN Direct boot kernel here: http://forum.xda-developers.com/showthread.php?t=1662295 its under the GB touchwiz based kernels. Flash that kernel, it will only boot to CWM and then restore your backup. But to let you know, there are better custom ICS ROMs that are very smooth and stable. Just make sure you use the safe kernel/recovery like this: http://forum.xda-developers.com/showthread.php?t=1767421 Then you can safely wipe and flash any ICS ROMs you choose.

I downloaded this: SPH-D710.EL29_CL852097_ROOTED-oc-sfx
but will it delete my apps, settings, msgs, etc?
It seems like it will factory restore and wipe everything>
Is there a way to just use the backup and reset it to then? If so can you please dumb down instructions and what it will do? I really really appreciate any help. I'm sure that once I go through it, it will make more sense but at this time, I'm overwhelmed by all the different setups and instructions from different places.
All I want is to restore a backup I have with GB. What is the easiest way to do that without losing info?

Ok get titanium back or a backup app. Then back up all your apps, just apps not system settings. then with titanium back up you can make a flashable zip. odin back to EL29 + CWM. let it boot up. Then power off, reboot into recovery. Flash Titanium backup Zip. Reboot. the titanium backup app will be on your phone. then restore apps only, not apps with data as ICS is very different. All done

Nandroids are used to restore backups. They are backups. If you backed up a GB rom. You can restore all your settings as long as you are on a GB rom.

I would love to LOVE ICS but the only thing I want my SGII to do without apps or widgets that I have to turn on and off to use:
Control orientation: I sometimes read in bed and it irks me that I have to use an app called Autorotate Switch to stop it from switching views, it does work but sometimes cuts off the top of a chapter. I can also hear it "fighting" with the system to prevent it from rotating based on the angle I'm holding it.
Control Brightness: The lowest setting isn't dim enough and I have to use a screen filter. Now with ICS it autoadjusts the lighting even when the toggle is off the setting to adjust brightness automatically! I hate this new feature.
Social Hub: I actually like this since it integrates msg and email and fb together. The new ICS lets me easily delete without confirmation, something that's good, but it broke update syncing contacts and the emails are huge and it's a big mess with scrolling and spacing.
Camera: All I want is to assign a shutter button to a camera
Phone: I want to call out in speaker automatically. I had set this up in WebOs and it was awesome especially for driving.
I seriously would consider trying out other ROMs if they can help me do this...

How would I do this? My friend made an nandroid in GB BEFORE I upgraded to ICS. Please and thank you in advance!

That is the GB direct boot kernel that I linked it the previous reply. Flash that kernel/recovery in ODIN or mobile ODIN. Then restore back up in backup/restore option in CWM recovery.

Issues with Epic 4G Touch ICS

Okay so my sister updated her epic a few days ago, and has been having nonstop problems with the ICS build FF18 there are just so many bugs in this and wondering if there is anything she can do without wiping her data on the phone.

She has two options. After ROOTING and flashing a custom recovery, she can either:
1. Backup all the data she wants: apps, sms, system settings, home screen layout and call log.She can use ROM Toolbox, My Backup Root or Titanium Backup. Those are the best. I personally recommend ROM Toolbox, but My Backup Root can backup sms and call logs.
After that she can flash any ROM she wants and then restore the data of all the apps.
2. She can try to format system only and then flash any ROM she wants. This is the easiest way but it is very risky to do it.
The first method is the most recommended. It is always recommended to flash a clean install.
Hope this helps. You can find all the links you want for Rooting and Flashing in the Android Development section.
If you need anything else, let us know...

About the only option you would have then is using Kies to backup, wipe the phone with a factory reset and restore through Kies.
If you have been reading through the threads, then you should know that the brick bug is still a major concern with the latest ota.
But you really don't have any other option if you're not going to root.

I don't blame her. It's no longer a great or even good phone for the majority of people. Even with custom roms and customizations I get about half the performance. They should have never released this update to the masses.

It is the apps that are on there. She has to start from a clean slate. Get Go BackUp, backup just contacts, sms, mms, and call log. Factory Reset. Then reinstall the the apps she wants from the Play Store. This worked for me.

you need update the device to stock FH13.. maybe fixed your issue about battery drain...

Running FH13 with 2 hours on screen time and 60% battery left. I started at about 90% after flashing the update patch from FF18 to FH13.

[Q] looking to switch roms? currently running jellybomb

Im new all this rooting and rom stuff and yesterday morning i successfully rooted and inststalled the jellybomb 14.0.0 jelly bean rom thanks to qbking77's on point videos. so the question is... how can i switch which rom im running? i like the jellybeen roms and im looking to explore more to see which better suits my needs. ive heard of doing clean/dirtry instals or something of the sort but i want the best and safest way possible so i dont run into any bricking trouble. please help?

Ok, read up on how to flash a recovery
Download the rom of your choice and place it.on your sdcard. Once you do that you can install roms by booting into recovery and finding the zip for the rom you want to flash and selecting it through the "install zip from sdcard" option
Now a clean install is whenyou wipe all partitions, aka blocks of your phones memory, (details farther down) and then install the rom zip. This method minimizes the chances for problems to occur after installing
A clean flash involves:
Formatting system
Formatting / Clearing data (also known as a factory reset)
Wiping cache
Wiping / Clearing dalvik cache
Now a dirty flash is when you just flash the new rom zip over whatever you're currently rumning, without clearing anything. This method is only recommended when flashing an updated version of the same rom, and even then, the nature of some updates can require you to do a clean flash.
One more thing, DO NOT flash any roms, mods, or zips for the international version. That usa surefire way to brick your debice because the partitions are completely different.
To learn more about how android and this.stuff works, I would suggest heading over to xda,university.com

Backup via CWM (RECOVERY) is mainly for restoring the same rom or going back to the rom you were running if experimenting, Now, can use apps such as Titanium backup to save all the other settings, apps and things. Once you flash your new rom, download it, open program and can restore your stuff that way. Personally, I'll wipe, start from scratch, sometimes i'll download an app i never use, and it just allows me to clear out the useless ones.. Happy flashing!

Yes as said above, a backup through recovery (also called a "nandroid" ) stores an EXACT image of the current state of your device. Meaning all data, all system files, all apps, radios, etc. Backing up through an app, like Titanium Backup, only backs up certain things like apps and app data
Basically, if you're trying any experimental stuff that may break your system (for example, flashing a new modem or testing to see if a certain kernel works), then a nandroid is the way to go because you can restore to an exact image of a state when everything was working

Yea I did that the 1st time and couldnt recover anything. Is there a certain way I should recover or maybe I did something wrong? Im not sure. Sorry if im sounding stupid but I cant return my phone if I screw it up so im tryin to be as safe as possible. Hopefully thats understandable

No no, its recovery
The recovery is basically something that allows you to install zips, it doesnt actually have much to do with recovering anything lol
But first do what was suggested right above me to check to see if you have a recovery installed
To get a more detailed description of what a recovery is and what it does, you can get over to xda-university and read through the "as user" section on recoveries

Think cwm has saved a few phones on here. Me I don't use a pc. Easy just with phone. If he's deleted his folder should he recoveR then it would bring that folder bk?
