Understanding the root process

Hi all,
I am interested in trying custom roms for various reasons on my G2. With the recent breakthrough in allowing full root, now seems to be a good time to try.
What I don't seem to be grasping is the whole process so, here is what I think* needs to be done, and I'd appreciate a more seasoned person to set me straight
1. Obtain full root via RAGE or oneclick Visionary method
2. Install RomManager
3. Obtain Rom
Here is where I kind of get blurry on the whole topic.
Once I have the files needed, Does RomManager do a nandroid backup so I can revert back in case I want to revert back to stock? Is this how I would revert back to stock or do I need to find the original pre or post OTA rom for the g2?
Does a program like Titanium Backup allow me to backup all of my apps and settings so they are easily restored no matter the rom, or if I revert back to stock?
Thanks in advance all, I have been reading every subset of these forums but I still feel a bit scared to try and wanted to get the facts straight before trying. I'm mostly just concerned that I wouldnt be able to revert back to stock if I had to.

rom manager can perform the backup, wipe, and install of a new ROM all in one go, you just need to tell rom manager where the ROM is on the sdcard and it will ask if you want to backup and/or wipe first

i do not know if titanium backup will restore the settings within the apps, but the backed up apps will work on any custom ROM you install on your phone.

Thank you for making that more clear!
So when wiping for a new rom, you want to wipe the cache, and do a full system wipe as well?
Lastly, now that I have the stock g2 rom backed up (did it manually via recovery, not in the rommanager app) I can flash as many roms I want to try them, but really can revert back to stock based on that backup. I guess what I'm saying is, I dont have to revert to stock before trying out a new rom right?
Thanks again, this is a huge help!

With your ROM backed up, that's essentially a "screenshot" of the state of your phone at that time. So yes, you can jump from ROM to ROM, clearing data, and whenever you're ready to go back to stock, you just restore your stock ROM and pretend nothing happened.
And yes, I recommend wiping everything when flashing a new ROM. Although if you're coming from the same type of ROM (I.E HTC Sense to another HTC Sense) you can probably get away with not wiping data.
And with Titanium Backup, I do reckon that settings are kept. When you restore apps, you're given the option to restore the app or app+data.

[Q] Few questions

Hello!
I still have Eclair 2.1 on my Epic 4g. It is rooted and right now I want upgrade it to Froyo.
How can I restore all apps and Data from the phone I have now. What do I need to do after flashing Rom to Epic 4G. Those apps that I already have installed, they will be restored somehow or I need to do something to restore it?
I've already did backup data and apps. Where can I reed something like FAQ with all that questions.
Please, sorry for stupid questions.
Also, I need some advice about the Rom. What rom better to install?
Thank you very much

First things first, wrong spot for this post...
2. titanium backup or any other good backup program that backs up to sd
back up the programs
install the rom
download titanium backup from the market again
reinstall the apps.
3. MY ROM (superheroes) otherwise I would go with mammon's that's the basis for my rom and his roms I have to say are the most stable and overall best out there... (my opinion)
There are a few other roms out there that are good roms, I would say check them out.
BTW this thread will most likely be moved or deleted !

Thank you very much. I have one more questhion. After upgrade to Froyo do I need to register all o my accounts or there is some way and it will be registered somehow?

I am glad this question was asked, because when I originally researched it, I found the same answer.
When using Titanium Backup, the restore process is tedious because it asks you for every single application if you want to install or not. If you have a lot of apps like I do, that was a pain. Any way around this?
ALSO, when doing a Titanium restore, it would indeed install all of my apps, but if I went to the "My apps" section of the Market, they wouldn't show. Is there any way to restore applications so that they show up in Market, which would allow them to be detected and updated (if a new version comes out)?

Odd thing happened to me when I flashed to noobnl's CM6 port. I didn't backup/restore any applications, but when I logged in to my google account, Market automatically reinstalled all of my apps (it must store my active app list server side?)

Keep my data after flashing a custom rom?

Forgive my ignorance.
I am following randyshear's excellent video and just rooted for the first time and wish to flash viperrom 4.0.2.a.
The only question I can't find an answer to is whether I can keep all of my data intact (my email accounts, the apps I've downloaded, etc), or whether this process will completely wipe out my data?
Maybe I'm already on the right track? I booted into clockwork recovery and selected "backup and restore" and made a backup to my sd card. I copied this nandroid backup to my PC. Will I be able to "restore" this after I flash the viperrom?
Thanks and sorry for the ignorance!

I prefer Mybackup Pro over Titanium.

Yep, my back up pro, or the free root version.

Or once you install your new ROM, you can boot back into recovery, go to backup and restore, then advanced restore, and just restore your data. This should restore all of your apps, settings, sms, ect without messing up the ROM.

I have flashed several roms several times waiting to find that ultimate rom that I cant live without, everytime i have had to try and figure out how to get all my data back, will this method work without fail? have you done this before. please let me know, if this is true you will have become my new hero. thanks

If you are coming from 2.1 or any other rom then data restore can cause fc and stabilit problems. I'm not saying this happens to everyone on every rom but it has happened to me multiple times after wiping data/cache 3 times flashing the rom, booting, clockwork data restore etc.. I generally don't try it anymore as it caused more problems than it solved. Just my 2 bytes.

Help with CWM Restore!

Hi,
Sorry if this has been answered already but I did search the forum and couldn't find an answer.
So 2 days ago I got into flashing my Sam GS2, I followed the instructions completely, I made a NAND backup of my current ROM.
I used ROM manager to install Cyanogen nightly ROM build 75, which I liked a lot but the camera didn't work and realised after it was a test build, so decided to go back to my current ROM. I went into CWM recovery and restored, within 5 mins I was back to like nothing happened.
I then download VillanROM 3.0, again a few bugs so I decided install TK ROM 3.6 I never restored to backup this time as I thought that wasn't necessary, but when I now restore my backup through CWM I get my settings but not my data?
Why is this? The backup file is still there and the same size as before, have I done something wrong?
The reason why I restored was after finding that TK ROM was a stable ROM I forgot to back up my GO SMS settings and Smart keyboard pro settings so I wanted to back up to SD card, re-install the apps and then just restore the settings, now it looks like I won't be able too.
Any help would be appreciated.
Thanks in advance.

Me for one fails to understand the problem .
jje

Well short version.
I did a NAND backup so I could go back to original ROM just incase things went pair shaped, I managed to restore to it after first flash, then on the 3rd time after realising that I forgot to back up certain app settings, I restored the NAND it does it reboots but only with settings and nothing else.
Can you help?

A failed nandroid restore looks to be a corrupt backup .
jje

Well I thought as much, thought I was doing something wrong.
Just have make sure I do 2 backups next time.
Thanks for the reply.

[Q] From custom to stock again

So I haven't really used any custom ROMs due to the huge work needed after flashing one, I have too many apps installed and save games that I don't wish to lose.
Well I've decided to check out a few of the ROMs today and see which one I will like best, but I would first like to ask how I would back up my stock ROM is the first place. Now as far as I know you can do a nandroid backup using CWM and so I did that, it made a backup of my stock ROM along with data files off all the apps.
Now let's say I've been with this custom ROM for a few weeks and I'm sick of it, and I would like to return to the stock one. Can I restore stock by flashing CWM again, going to the backup menu and choose restore and then browse to the backup I made? Will it restore my stock ROM + data without problems?
Another thing I'm curious to know is, what's the best way to backup all of my apps along with their save games so that I can restore them to the custom ROM once I've flashed it? I've read about Titanium Backup but I do not see a "Select all" option, backup one after another would be a pain.
I hope I didnt confuse anyone with all these questions.

Use batch operation in TBackup

Stupid me, how could I have not noticed that option. Thanks I have just started backing everything up, I suppose the correct option is "Backup all user apps + system data"?
As for the stock ROM backup, will it work as I said? I've read that CWM has bugs when it comes to restoring such nandroid backups. Also do I need to wipe cache and data before I can restore my stock nandroid backup?

1) Yes, its the correct option. It even backups save games and the entire data
2) It doesnt matter if you wipe data or not. But its fine if you dont do that. I dont wipe data at every nandroid restore and had no problems. Either way its the same, no need to worry about this. CWM backups wont restore or give some problems only when you restore a backup with different kernel. For restoring to work perfectly , the present kernel(before restore) and to be restored kernel must be the same.

Great, thank you.
For now I have transfered all the files from my TitaniumBackup folder to my computer. I am planning on transferring them back to my SD card once the ROM flashing is complete. After I put the TitaniumBackup folder on my SD card, I install Titanium Backup again and it will read the backups right? Then all I do is choose the option to restore them all and it will work with no problems?
Sorry again for too much questions but I always like to be on the safe side when doing such things, :angel: I crapped my pants when I ended up with a bootloop on my old phone :laugh:
