Flashing a new ROM on rooted Eris and other questions

I know there are tutuorials for this. I found a few and most of them either expect me to fully understand adb shell commands or understand linux, of which I do very little. I have the rooted 2.1 OTA on my Eris currently. I wanted to start trying out other ROMs on the phone. I've done a nandroid backup, but from searching around I read that it doesn't back up apps or user data, to an extent.
1) I get the error message "Run Nandroid +ext via adb!" when trying to backup everything using nandroid + ext. I also get the same message when trying to use a BART backup.
2) What is the difference between the two? (BART and nandroid)
3) What are the adb commands to use these?
4) How can I make a complete "screenshot" of my phone to restore everything back to its current state? Is this what BART/nandroid+ext do? I need to be sure in case I need the phone restored to working status very quickly.
5) Is apps2SD really that useful? I only run like 45 apps.
6) Does overclocking have any downsides? (I know the phone can lock up if you push it too far, so other than this.)
I think that's it. I've softmodded consoles and a few random electronics but phones are a new one. Sorry if half of these have been answered. I haven't been able to find much about this stuff in laymen's terms.

1) if you get that message on restore 99% of the time that means your battery is low.
2) I have no idea what the difference is, but NAND always works great for me.
3) You would need to flash the parts of a NAND Backup via fastboot (correct me if I'm wrong). It's a pain in the ass for the most part.
4) NAND backup and restore makes a "screenshot". It will turn your phone to exactly how it was when u made the backup (make sure you wipe first though )
5) APP2Sd is only if you feel you need it. I use it, but is not required at all. If you have enough free space that why bother, but if not it's good utility to have available.
6) OC is awesome only downside is battery and that is barely their. You can also bork your phone if you set it to high. Some phones can handle over 710 some cannot. The only way you will know for yourself is if you try!
Go for the aloysius rom if you need a or want a new rom to flash

Awesome, thanks. I'll check that ROM out and see if I can get to flashing after work.
1) This isn't when restoring, it's when I'm trying to actually make a backup. Nandroid works fine, but nandroid +ext and BART both give me errors about adb.
Any other suggestions/answers?

Oh, one more question I forgot.
Code:
adb pull data/app desktop
Was using this to pull apps from my phone to the computer. After I did, I couldn't find them on the computer. I assumed they'd go to the desktop, but apparently I was wrong? Where are they?

You only have to do nandroid without the +ext. You only use ext when you have a partition on your sd card (for running apps2sd). Try a plain ole nandroid. As far as bart goes, I've never heard of anybody using it.

is there a way to name the nandroid backups so you know which one is which when you go to restore? or can you only have one at a time?

You can have as many as your sd card will hold. They will be in folder on your sd card called "nandroid" and you can rename however you see fit, just make sure you Do Not put any spaces in the name.

Okay, if a nandroid backup makes a total system image incl. apps and user data, I should be good to go.
Still wondering about how to pull apks and where they go. Any ideas there? See one of my above posts about it.
Also, I need to backup my ENTIRE SD card before a wipe, right?

Need a NOOB guide to EVO and Backing up.

I have read MANY threads, hunderds of pages.. I have rooted my phone... (the hard way, Thanks Toast) and I still really dont "GET IT.."
I would love a white board on the components of the whole process.. including titanium backup..
Meaning a writeup, showing each part of the system, and a paragraph on what it does..
Us Droidnoobs would really like to understand how this works from a high level... (or maybe I just belong on a short yellow bus...lol)
I just dont get what is required for each part, and what it affects..
NandUnlock: What does this do for us?
Engineering SPL: What is this?
Clockwork: ( i loved the movie.. but don't get how it pertains to the phone)
But seriously.. I dont know what is is, so how can I pick from the 2 avaiable?
Recovery: What parts of things dose this include? What is its function?
Nandroid back up: Do i need this and Titanium BK? Which will do what?
I want to figout how to back up my EVO and install new roms, and then re populate all my settings and data.. i use exchange, so i don't care about emails and contacts, but i have other email (pop) accts, that i want the accounts and preferences retained..
I have to root my bosses phone later today, and was wondering if i can do it with out it being activated? I was gonna get it rooted, and then activate it on Monday when I see him..

I'm by far not the most knowledgeable person but I can answer some of your questions... Anyone that knows better please correct me and let me know.
NandUnlock: What does this do for us?
This is required to install custom ROMs. Without it, you could install signed ROMs from Sprint (ie: Engineering ROM or Stock ROM) but not custom ROMs (like Fresh, DC, Cyanogen...).
Engineering SPL: What is this?
The way I understand it's a ROM version before the Stock ROM that Sprint/HTC probably used to test the phone before release. We use it because it is special in that it allows us to unlock the NAND part (Sprint stock ROM does not allow this).
Clockwork: ( i loved the movie.. but don't get how it pertains to the phone)
But seriously.. I dont know what is is, so how can I pick from the 2 avaiable?
Err... Not sure picking what...? But Clockwork is a great recovery app that makes it easy to drop files on the phone even if it wont boot or install custom ROMs/updates whether they are signed or not. It also makes backing up your phone (everything including the ROM, AFAIK, I use it and very happy with it) a snap. It reboots your phone to do this.
Recovery: What parts of things dose this include? What is its function?
Recovery is a special part of your phone that is away from the operating system. The OS can't install on top of itself, so you need separate code to do it. It's also a tool for when the OS is broken/not functioning and doing diagnostics.
Nandroid back up: Do i need this and Titanium BK? Which will do what?
I should know more about nandroid... but don't really. I think it backs up the recovery part/hboot? Errr... someone help me on this one.
Titanium backup makes it easy to backup your paid apps and even stock/OEM apps that came from the mfr or carrier. It has other backup functions, too.
I want to figout how to back up my EVO and install new roms, and then re populate all my settings and data.. i use exchange, so i don't care about emails and contacts, but i have other email (pop) accts, that i want the accounts and preferences retained..
Can't think of how to do this off the top of my head. Does it store on SD card? I can't be sure. I think there's an option to store this information on the SD card, so that should work AFAIK.
I have to root my bosses phone later today, and was wondering if i can do it with out it being activated? I was gonna get it rooted, and then activate it on Monday when I see him..
I'm pretty sure you can I don't see any reason why not but I've never encountered that situation before...
Hope this is helpful.

Thanks..
anyone else have their views on my questions? or differences fro the above?
thanks in advance..

I need more info on the Nandroid back up please..

Clockwork and ArmonRA both provide the capability to BACKUP your ROM, referred to as Nandroid. I know there are some plus and - to each. You should get in the habbit of ALWAYS taking a nandroid backup before you try a new rom. Give yourself something to fall back on.
TB lets you backup applications and OS settings and restore them. It will relink your apps to the market, which other apps will not do.
You must be very careful restoring OS settings, as each rom is built differently. Setting in DC will not work in Fresh for instance. So you can use TB to restore all your apps quickly, but you should still do the configuration manually.
You can root a non activated phone, but I think the activation process can cause you problems. I would wait until it is activated.

Clockwork: ( i loved the movie.. but don't get how it pertains to the phone) But seriously.. I dont know what is is, so how can I pick from the 2 avaiable?
i use AmonRA. why? because it seems that the general rule of thumb is that clockwork is easier for us noobs, but if anyone has issues they are told to use RA. so, i just use RA. i used clockwork for a bit but have i switched to RA; it's really not much different interface. the only thing i wish RA would do would be to allow me to 'browse for the zip to be flashed'. (oh yeah in RA...press both up/down at the same time to go back a level)
i believe you can use clockwork and simply 'flashover to RA' as needed from within the running OS. it can flash RA or Clkwrk or old version. i had something happen last month and wasn't sure what i did...once i got RA working, i said screw it and stayed with it. Clockwork does have a nice interface designed to make it easier to test out new ROMs...RA does not have this. is it needed? not really.
Nandroid back up: Do i need this and Titanium BK? Which will do what?
i use both. when i'm doing a buch of tweaks or testing a ROM, i make sure to make a nandroid backup (think Norton Ghost for phones). i also use titanium, mainly for when i install a new ROM. it allows me to restore just the apps and their settings onto the new ROM. its not perfect but does get most things. you'll need to setup things like email, facebook, twitter, meebo logins, etc.
so, although i often take a nandroid and titanium backup at abotu the same time, they are used to restore slightly differently. nandriod is my 'oh crap, this is bad i want to get off this ride' and titanium is my 'sweet, now how do i get my apps back in place without manually installing and config'ing each and every one'
(make sure to read about 'user apps' vs 'system data' w/ titanium).
I want to figout how to back up my EVO and install new roms, and then re populate all my settings and data.. i use exchange, so i don't care about emails and contacts, but i have other email (pop) accts, that i want the accounts and preferences retained..
titanium will get most of this. but i always seem to have to some tweaking cause some app has been installed or whatnot since my last backup. oh...and the titanium paid version will install all apps w/o manual intervention.
enjoy.

Clockwork: ( i loved the movie.. but don't get how it pertains to the phone)
Use either Clockwork or Amon RA, will not make a difference. Clockwork is used in ROM Manager as default.
Recovery: What parts of things dose this include? What is its function?
Recovery (volume down + power) allows you to flash zip files (rom, radio, apps, whatever), do manual nandroid backup, wipe your device, etc. Clockwork and Amon RA are both recoveries that do essentially the same thing.
Nandroid back up: Do i need this and Titanium BK? Which will do what?
Nandroid backups EVERYTHING on your phone, all apps, data, including rom, radio and kernel. It can be accessed via recovery or via an app called ROM manager.
Titanium Backup allows you to backup all your apps and data. You may ask why would you want to use Titanium Backup if Nandroid backs up everything? When you flash a new rom, you can use Titanium Backup to restore all your apps. (Otherwise restoring via Nandroid will restore your old rom over your newly flashed one)
I want to figout how to back up my EVO and install new roms, and then re populate all my settings and data.. i use exchange, so i don't care about emails and contacts, but i have other email (pop) accts, that i want the accounts and preferences retained..
Search the Market for email backup. Your google account restores all your contacts anyways.

Quick addition for your pop3 accounts. You can actually use GMail to push all your pop accounts. this will retain all the settings for those accounts if you reflash a new rom. There is a tutorial on here somewhere on how to do that. The GMAil push lets you set up labels and seperate email folders for your different pop3's also, you can add labels through the web interface and they will show up on your phone automatically, providing of course you have them set up to sync.
Another quick comment on Nandroid, this is a carbon image of your phne basically, so if you flash a new rom and then do a nandroid it will restore your phone to exactly how it was when you did the backup. So it wont work as an app backup, because if you flash a new rom and use nandroid you will be completed reverted to the rom you were on when you backed up. Make sense? Use titanium or there is even a backup called "mybackup" in the market which works also, I personally use titanium but my backup is a one click everything backup. Although it does not restore your market links, which allow you to get update notifications for your market apps.

Perfectly Clone one Vibrant to another vibrant

I have a Vibrant with fusion 1.1 that is going back to T-mobile. Is there a way to just clone everything on this phone to the new phone.
Can I just copy Titanium backup form the old phone and put it on the sd card of the new one. Is there a better method?

You need to flash back to stock using odin, just go to the development section and click om the.sticky, under odin roms. Click the.stock one and flash,

I'd do a nandroid and back up the apps and data in titanium and save them to the SD and then put that SD in the new phone that comes.

What would happen if I copied all the contents of the internal memory (all files ,all folders) then copied those over the contents of the new phones internal memory?. Nandroid and TB are not normally saved to the external SD card.
Or should I just load the new rom on the new phone and just copy the TB folder to the new phone and restore from that?

Nandroid and titanium are a good start but neither of those will do things like modem files.
So I would add on the new phone do a base install of fusion 1.1 with the appropriate kernel, i think you said was your rom, then a nandroid restore and that should get you there

I'll chime in with my opinion. Granted my opinion comes from my experiences constantly experimenting with different roms. I've flashed the phone this month almost as often as I've received actual phone calls for crying out loud!
The amount of time expended on looking for such a perfect method seems to be greater than the amount of time spent merely reconstructing an equivalent environment.
Keeping all of my contacts on google and using appbrain to have the ability to keep a known inventory of apps...I can reconstruct my daily driver environment from one rom to another in about 30 minutes max without the need to explicitly backup anything.
Though this may not work for everyone, it surely would work for most. Just a thought...

Using AppBrain would mean you would have to constantly re-download your apps. Also, this does not save the settings and what about apps that are not on the market?
I use Titanium Backup if I want to transfer all my apps and settings. Nandroid would be very appropriate to transfer over all the of phone's data, granted you also manually include the correct modem and kernel.
Doing a Titanium Restore surely takes less time then redownloading and installing from the market, especially if you have the Pro version as it is MUCH MUCH quicker.

Titanium can save some time, but honestly not enough to write home about, at least for me. It's a matter of a few minutes different in my experience.
The reason why I do not use Titanium, despite the fact that it can save some time is that it can lead to complications especially when bouncing between 2.1 and 2.2 derivative roms, depending on what you back up of course. I'll use it when I'm staying within the domain of 2.1...or staying within the domain of 2.2. Crossing those domains however I never use Titanium. I've had more problems than not, and admittedly that may be due to my ignorance of what things are truly safe to restore across different versions of Android.
Then again I'm probably unusual compared to the OP, in that I experiment with EVERYTHING, up to and including a little bit of my own firmware cooking after the fact. Every firmware and experimental firmware and filesystem hack has at some point been on this phone, but that's how I roll.
Doing without deliberate backups hasn't drastically changed my restore times. Setting up the few apps that require setup takes a matter of seconds when I decide to use that app.

It's nice to get a fresh install - just TB and and reinstall after!

if you want exact - nandroid
otherwise use TitaniumBackup Pro

This is what I would do. I would perform a nandroid. After doing so I would then copy everything in the internal sd to your computer. When the new phone comes. Copy everything into the new phone's internal sd. Root your phone, install clockwork mod. Flash a new rom if you want if not no biggy. Load up into clockwork mod, do an advanced restore, restore data only. Reboot. Reboot again. Load back into clockwork mod, clear cache and dalvik. Reboot twice. Run fix permissions. Reboot. Everything should work with no errors and it will look identical to your last vibrant. You could condense this but I wrote it so that you could install buncha diff roms without having to do titanium restore because that just takes a ****ing long time if you have a **** load of apps installed.

Thanks for the lengthy explanation , that makes the most sense.
I will try this method . Thanks for taking the time.

Hey rancome7 - did you try this method? How did it work for you.. I may just do this right now as im in the same situation of wanting to clone my Vibrant to a new Vibrant

Question - wont restoring data from a nandroid after installing a new ROM cause the rom to act funny since the old data may not agree with it or overwrite something?

[Q] Noob questions galore ;)

Hi guys,
First of all (in case you didn't realize it), I'm an android noob. This is my first Android phone (my employer tried to give me an iPhone, but caved when I told them I'd just stick it in my drawer and save it as an emergency phone) and I just rooted it
Now...I made a backup of it after rooting. This should get me back to stock if I need it, right? Should I copy it off the phone? I guess it will be removed if I have to wipe...?...
Also; will I retain my settings, sms/mms etc etc if I use a custom ROM? This is my main concern at the moment, as I want something more fancy and hopefully less energy consuming ROM.
Cheers!

Hi there!
if you made the backup just after rooting, if you run that Backup (through CWM etc) it will revert the phone back to how it was at the time of the backup, so if you didnt have any settings,sms,Apps etc they will not show. you can copy the backup file if you wish to but i believe (not 100%) the backups are stored on External SD and as a result are not lost on a Factory Reset/Wipe
Some Custom ROMS (Litening ROM i use) allow you to flash with no loss of data, including all your apps, SMS and settings. Basically you have the exact same phone layout but with a Spiffy,fast,Fresh rom they are really easy to flash with ODIN, now im not sure if other Roms (Villain, Cognition, etc) retain the Data partition on flashing you would need to check out the specific Threads on the Android Development section of the forum
hope that helped !

Thanks - that was helpful I will look into the other ROMS and decide from there.
Do you know if any of the SGS2 ROMs have more themes available? I get bored easily, and it would be great to change the look and feel every now and then

well being that the phone is still relatively new and still not available for the North American market, the development for it is still small. However, the CM7 team are developing roms for it, and a lot of other custom roms are based off CM7, so there should be a good selection of roms in the near future. the sgs2 is one of, if not the most anticipated android device this year, so i'm sure rom selection wouldn't be a problem.

Thanks, guys
I just bought Titanium Backup after some recommendation in another thread. Is there anything I should be aware of, or any recommendations, when making a backup before trying out other ROMs?

Whenever i do anything such as update/change my ROM, i do a Ti backup of all my apps (incase they go missing) then a CWM backup of my System which i can roll back to if i have any problems
Also, just to 2nd what p00kienrayray Said, the only ROMS i know of which support themes are MIUI and CM7 which should hopefully work fully soon

Yes, there *definitely is* a recommendation, when making a backup before trying a rom which wipes your phone, check out the message I sent to TB developer..
"Hi, I bought titanium few days ago to help the transition from my Magic to the new Galaxy S2. I used to use My backup Pro but appreciated the apps freezing function of Titanium that could possibly help avoid the battery drain problem on the S2 due to the Samsung WiFi sharing bug.
I had quite a bad experience, though, regarding a hard reset I had to perform on the phone, which I previously backed up with Titanium: the default backup directory is /mnt/sdcard but that corresponds to the internal memory on the S2, while the external one is located in /mnt/sdcard/external_sd (if I am not wrong). That led to losing a week worth of photos (the one part I couldn't really get back, given that I had a week old backup made with SMS Backup & Restore + Call Log backup & Restore made on the Magic).
Ok, lesson learnt for me but may I suggest that the default directory can be automatically set to /mnt/sdcard/external_sd if the terminal is an S2, for future users not to be unsatisfied? Is it something that could be implemented in TB?
Thanks for listening,
*************
PS well, shame on Samsung as well for such a weird choice... I would have set /mnt/sdcard for the external one and /mnt/internal_sd for the internal one... and don't understand why the hard reset (performed through the *2737*3655# code - if I remember correctly) does reset the internal memory which if I am not wrong is a separate partition from the system."
CONFIGURE YOUR TB BACKUP DIR TO /mnt/sdcard/external_sd BEFORE DOING ANYTHING ELSE
Not to mention that some apps like SMS Backup & Restore do not allow you to change the dir, therefore you have to manually move the backup results after you have finished

[Q] Keeping data (sms/mms, contacts, call log, ect.) between switching ROMs?

Hello all. I have a question about how I can backup/restore my sms, call logs, contacts, without use of google 'cloud' (I never put these info's online)?
Here's my scenario:
I recently learned how to switch my ROM from SD to NAND. Luckily the ROM I chose long ago just experimenting was AmeriCanAndroid on SD, which happened to have a NAND counterpart so using Titanium Backup I was able to completely backup and restore everything with no problem/no quirks.
I now want to change my NAND ROM from AmeriCanAndroid to RUNNYMEDE 0.82.401.1 - Android 2.3.5 - Sense 3.5 (because I have a heartOn for sense).
I got the hang of using CWM recovery, and changing the cache and data sizes, but the hurting started when I got into the ROM and used Titanium to restore the backup I made in AmeriCan to use in this new one. I now keep getting Force Close errors.
I'll make another post about that, but what I specifically would like to know is how I can backup that info and restore it, across roms, no matter what? Is there a sure fire way for that?

Not really, with NAND, you almost always (95%) have to wipe all data and system info, like formatting your computer to put a new OS on it (Win -> Linux). The only thing I can tell you is I personally use MyBackup Pro, has not once EVER given me an issue, and I have had it since the G1 days .
I have heard what your using, Titanium Backup is good too, so if you purchased it or are fine with free version, just keep using that. Backup your apps/data, flash new ROM, login to google, download titanium backup, and restore it all. It should work with no problems, NAND is NAND, a ROM is a ROM, they all run the same. SD backups will not work with NAND I dont believe.
Dont be afraid to experiment (follow ALL directions), backing up is the easy part, restoring is fairly easy, but the ROMS are all different and are very nice, THANKS TO THE GREAT DEVELOPERS!!!
