If that didnt help, Google "what is nand unlock XDA EVO" tons of threads come up.

Nandroid basically backsup all your info. So if anything bad happens your phone will be restored to its last backup. As for installing roms. Download ROM manager. Goto install Rom from SD card. Locate the zip file and check both boxes. Making sure you backup your apps to your SD card via titanium backup. And contacts via export contacts. This will wipe all data and cache. And Nandroid backup your phone

Yes. If you rename it, do NOT put spaces in the file name.

i got all the answers you need. pm me if you have more questions.
nand unlock lets you alter the system partition (software) drastically and to your heart's content.
your phone crashed because you are on stock (i am guessing) but you need a de-odexed rom to flash a theme. deodexed means the .odex files that hold stuff for apk files are combined with the apks. so they will not contradict causing crashes. MAKE SURE TO WIPE DATA CACHE AND DALVIK CACHE TWICE EACH THROUGH AMON RA RECOVERY AND MAKE A NANDROID WITH AMON RA RECOVERY. ALWAYS HAVE AT LEAST ONE BACKUP MAKE WITH AMON RA RECOVERY ON YOUR SD CARD IN CASE YOU LOSE YOUR 4G RSA KEYS AND YU WILL NEVER EVER BE ABLE TO CONNECT TO 4G

When you flash anything. Whether it be a Rom or any signed zip file. The easiest way is through Rom manager as I explained. "Nandroid is a set of tools that will enable anyone who has root on their Android device to make FULL system backups, in case something goes wrong or you want to try out that new experimental ROM/theme." -cyanogen.

Amon_Ra not creating md5 files

last night i made a nandroid backup and when i went to restore it, it quit right away and said"nandroid file corrupt" or something to that effect. when i compared backupo to eachother i noticed the md5 files were not being created, so i tried reflashing amon ra 2.3 it didnt work even went back to cwm and then to amon ra and it didnt work. any help with this would be greatly appreciated. thanks!

Are you renaming the backup file and if so are you using special characters in the name? Also, what do you mean when you say amon RA is creating an md5? I am unaware that it did such a thing. You said you also switched to CWM. Were you able to make a nandroid backup with it? By the way, did you happen to rename the folder containing the nandroid backup?

no not changing the name at all and i dont think ive done anything concerning the recovery since the last nandroid i made. the nandroid files normally contain 9 files inside the new ones i try and make only contain 8 and the one missinf is the md5 file, no i havent tried with cmw i will now though gimme a sec and ill report back. thank you for your help.

Yes it creates a full useable backup with CMW, but i would love to figure out whats wrong with Amon_Ra. Maybe downgrade it and then upgrade would that maybe work? ill try it when i get home from work.
Edit: I think i know what may be wrong- With CMW when i try and wipe dalvik it says "unknown volume for path [sd/ext]" and last night when i tried to flash a new rom it didnt format the sd/ext because when i went to the app drawer all the old apps were still there in the new rom. and now that i look back at the back up log for the back up i just created in CMW it says no sd/ext found. so i guess i need to fix the sd/ext path. would this some how be dome in dtapp2sd?

I get it. You're referring to the nandroid.md5 file "within" the backup itself. Why do you have 9 files inside your backup? Are you selecting to back up EVERYTHING when you make a nandroid backup? If so, you don't need to do that. With amon RA, you only need to use the default selections, unless you have apps stored on sd-ext partition then you would also select it. Prior to making a nandroid backup, I suggest you wipe the cache & dalvik, if you're not already doing so.

amon RA v2.3 is "solid". I use it and I highly recommend it. Try downloading a fresh copy of amon RA and reflash it. I have amon RA v2.3 Haus Mod. I could send you a link to download it from my DropBox, if you'd like.
UPDATE: I sent ou the link via PM, just in case you were interested.

The SD-ext should have been detected. I know it is in amon RA and you're right, if your apps were still present after a fresh install of a new rom, the ssd-ext was not properly wiped. As for dt app2sd, wouldn't you have to repartition your SD card? I mean, you would have to create the EXT2 Partition. Then use the option to upgrage EXT2 to EXT3, at least that's how you would do it via amon RA. I don't use CWM.

So your saying when i nandroid BU i only need to back up what is checked by default and sd-ext because i do have an ext-3 partition set up, and thats it? yeah i have been backing up everything and it takes for ever. so i no longer need to check cache, recovery, wimax or .android_secure ? thanks for your help brother!!

That is correct. It is also a good idea to make nandroid of your wimax. With amon RA, the nandroid will have have names similar to BDEAS-20110409-1532. The letters prior to the first hyphen tells you what was backed up. B for boot, D for data, E for ext partition, A for Android.secure and S for system. The middle portion is the date the nandroid was created. I usually rename the middle portion. Anyway, take care and enjoy your weekend.

ROM Hopping

I want to play with different ROMs (i.e., Cyanogen 7.x, Kingdom and other leaked stock ROMs) but I would like to backup and restore my apps+data for use between the ROMS *AND* have my current stock ROM (yes, its rooted) imaged/ghost'd so I can clone back to it if I don't like the other ROMs (like Ghost, DriveImage, ShadowProtect does for PCs). Is this possible? If so, how?

It's built into recoveries. It's called a nandroid backup. I switch betweek MikFroyo and CyanogenMod7 by using recoveries. If you've rooted your phone you should already know how to do it

To back up your current rom:
reboot into recovery
wipe cache/dalvik (trust me, it's faster that way)
select backup
select nandroid backup (not restore)
it'll give you a list of options to select. Select all but the last 2. (which is like android.secure and your sd card. don't need backups for that)
select "perform backup".
Be patient, it takes several minutes to perform the backup. This will back up your rom as it is right now. After that reboot, use your favorite file manager, go into the nandroid folder and rename that nandroid backup to whatever you want (remember NO SPACES IN THE NAME or it WON'T WORK. Don't name it MikFroyo 4.61, name it MikFroyo_4.61, for example). Then, no matter what, you can restore to how your rom is at the very moment you saved it.
If you wanna just back up apps, get "titanium backup" from the market and back up all your apps. Then you can restore just the apps to whatever rom you flash.
Any flashaholics have nandroid backups and titanium backups.
I flash back and forth between Virus 2.1 Sense, the gingerbread w/sense leak and mikfroyo 4.61 and have nandroids for all three. Can't wait for Kingdom to be officially released (3.0 and 4g? sign me the hell up!)
Hope this helps. Us flashaholics gotta stick together.

To add to what AbsolutZeroGI stated, I would recommend, being this is your first time making backups and we don't know how your SD card is partitioned, that you select to backup your boot, data, system, android.secure, sdext and wimax.For all other backups, just use the default options. If your recovery is amon RA, the aforementioned options are clearly seen, bit I'm not sure about ClockworkMod. It's been too long since I last used it.

I don't think how the sd card is formatted matters. I formatted mine for virus 2.1 sense B3 and my mikfroyo and stock still work perfectly. It says to back up the sd card on the computer before you format and put it back after you're done.
Not saying you're wrong, but a backup with .secure and sdext takes FOREVER (like half an hour the last time I tried it, maybe longer) and it's not really necessary.

I respectfully disagree. Before making a backup, I always wipe cache & dalvik and when I had all of my apps on the sdext partition, the backup was maybe a minute longer than using the default settings. Furthermore, a few of my apps are on android,secure and the backup time is the same. At least that has been my experience....

I'd have to agree. When I backup my android secure it only takes about a minute or 2 extra than the regular settings...never a half and hours..that's just ludicrous.

Rats! I was hoping I could just dd this ***** and be done with it.
What's this .secure, android.secure and sdext business? I was picking up what y'all were putting down until y'all mentioned that stuff (I've yet to come across that stuff in my nandroid'n/rooting/ROM'n adventures so far).

Also if you backup your apps using Titanium Backup, make sure when you restore you are not restoring and system apps from a Sense Rom to an AOSP Rom or vice verse. I will throw your phone into a Bootloop more than likely and you will have to restore your backup and start all over.

When you go into recovery to create a nandroid backup using amon RA, System, Data and Boot are selected by default to be backed up. Most of the time, that is all that is required and all you have to do is initiate the backup. However, some people's device is setup a little differently and to prevent their devices from bootlooping at the rom's splash screen, they have to select sdext and/or android.secure to also be backed up when creating a nandroid backup. Both are where certain apps are sometimes stored.

There's an adb way to pull and copy the wimax image, but if you mount the phone to the pc, copy the wimax to the pc and have an extra copy.
If you're on clockwork recovery, the wimax is already in the backup. If you're on amon_ra 2.3, you'll need to make a backup of it specifically.

[Q] Nandroids

What exactly does a Nandroid backup. Is it like creating a Hard Drive image for windows?
After installing CM9RC I want to go back to my previous stock configuration. If I restore my phone with a nandroid, will I recover everything previously installed on my phone? I am assuming the stuff in the sdcard folder gets excluded from the wipe right?
Thanks in advanced,
Aphis

Yup a Nandroid is more or less like a restore point. And yes excluding sdcard.

Yes. Note that a nandroid backups up the system partition, the boot partition, the recovery partition and the userdata partition (excl. /sdcard). It does not back up your radio or bootloader, so if you change those, you will have to flash them separately.

EDIT: Ninja'd by WiredPirate.

Thanks for the quick response.
That would mean that if before creating the nandroid I had permanently installed CWM and rooted the phone, restoring the nandroid would keep my phone with CWM and root right?

its a snapshot. whatever you had at that moment when it was created is what you will have when you restore to it.

[q] twrp nandroid not restoring?!

I have not seen this problem. TWRP will only restore what was backed up. Are you sure that the data was backed up? Go to the folder where your backup is saved... do you see a file "data.ext4.win" in addition to the "system.ext4.win". If no data file then the data partition was not backed up.
If the data backup is there but you are still not seeing the data restored you may want to look at the recovery log after you restore to see what happened.

When you run the backup you have to select which partitions are to be backed up. For some reason it did not run in your case.

In TWRP's Backup menu, there are 5 check boxes giving you the choice of what to backup. System, Data, Boot are checked by default, leaving Recovery & Cache to be selected (if you choose to do so). I just made backups of 2 custom ROMS, and my stock rooted ROM, and only used the default settings during backup. There were 6 files created in each backup: boot.emmc.win; boot.emmc.win.md5; data.ext4.win; data.ext4.win.md5; system.ext4.win; system.ext4.win.md5. After I made these backups, I tested each to see if I could go from one ROM to another without problems, and I could. The data.ext4.win & system.ext4.win should be big files in size as well.
I'm using TWRP 2.3.1.0, and have had zero problems with it (knock wood!)
