I tried Prime 1.6r2 ROM (Was on Revolver 1.3) and did a CWM backup right before I flashed Prime and then decided to go back to revolver, I ran the restore and it appears that It did not restore the Kernel or the BOOT partition. I had to reflash the Revolver to get back. I have a Viewsonic G tablet and the CWM backup/restore does everything except SDCARD and RECOVERY partition. I thought that CWM backup/Restore for the Transformer would work the same. Is this normal?

I don't know anything about Prime or Revolver, but I know that CWM should backup/restore a kernel (or boot.img). If it didn't, it would be chaos in kernel + userspace land, because /system/lib/modules must match the kernel, and it sounds like it's restoring /system/... no problem.
You should be able to figure this out by looking at the list of modules supplied with the kernel in Prime vs. Revolver, then go to root explorer, nav to /system/lib/modules, and see which it matches, then for example, try a 'modprobe {modulename}.ko (like .. cifs.ko) (e.g. modprobe cifs), and if you get a version conflict, you are , for some reason, messed up. Well:: I don't know if those ROM's supply modprobe, so use insmod if they don't. (you could easily do this from adb shell, or onboard from terminal emulator).
I would just use nvflash to backup and restore the kernel in case cwm is messed up on your box.
Just to add to what I mentioned:: I think that if you just try to restore a kernel (/boot) then you'll have the trouble I mentioned above as well, unless the builder decided to link all the 'module functionality' right into it.
Here is what happened. I was on Revolver 1.3 and Over-clocked to 1.504 via SetCPU and all was great. I then wanted to try Prime 1.6r2 and flashed it. When i ran SetCPU it only allowed me to go to 1000Mhz (No overclock! I realized that I would need to install a OC Kernel if I wanted to OC). I played with it for a while and decided to go back to Revolver 1.3. I had done a CWM Backup before I flashed Prime 1.6r2 and so I though that all I needed to do was do a CWM restore which I did. After re-boot, I ran SetCPU as I assmed I was back to Revolver 1.3 and it still did not allow any Over Clock. Strange?? I then re-flashed the Revolver Roms and I was able to Over clock again. When CWM backup is run, SYSTEM, DATA and CACHE area the only partitions I see being backed up (No boot) Since many of the ROM flash boot (Or at least they say they are) I assumed the CWM backup would also backup the Boot Image. I am not sure where "KERNEL"s are stored (I am guessing SYSTEM) so not sure why I am getting the results I am getting.
Update:
when back and read up on the CWM Recovery Backup/Restore and found this line on the first page...
Nandroid backups and restores don't touch the boot or recovery partitions.
So Mystery is solved Since it appears that flashing a Kernel is flashing the boot partition not the /System as I assumed.
Maybe nice to have an option CWM backup/restore to backup the /boot as well.

That's news to me and I also verified you're correct on my TF. I also looked back at my phone and it used to make 'recovery' and 'boot' backups as well as the other 3. I just guessed that it still did, but you're right. I haven't looked at advanced restore yet where I used to be able to restore any of those partitions, but it won't matter since they're not being backed up.
Since I got this TF a week ago or so, I've been using nvflash for the entire backups in addition to cwm now & then. In the days where cwm backed up everything, the restores worked fine and were much less hassle. Possibly , since cwm is open source, we could fix it to do the entire backup, (not really sure). You could use the little tutorial in the DEV section to use NVFLASH to extract from a 3.2 blob the kernel and package it as a boot.img file. This is either flash-able via nvflash or possibly even restorable by advanced CWM, not sure once again. Thanks for the info.

CWM .img files are in yaffs format, so they aren't the same as nvflash images. Google code has an unyaffs tool. There is also a mkyaffs2image tool. I haven't tried yaffing a directory and flashing it via CWM, but it sounds like it should work. There might be issues with persmissions, pids, and md5sums.
Nvflash images are more like dd dumps. Some of the partitions are actually ext3/4 file systems that you can mount. "file *" in the backup directory should provide 15 mins of entertainment. I usually mount them ro so that the journal doesn't get messed up.
I wonder if it is just an issue where the author of CWM for the transformer can just add the /boot to the list of partitons that are backed up. Is the /boot partition in a format that CWM cannot process and that it why it is skipped? I own a G-Tablet and it does backup the /boot. I will post to the CWM thread and ask what would be involved. My main issue is that so many people believe that this Nandroid backup is for everything and in the case of the Asus Transformer it is not! Most users would find using NVFlash as the backup method to be a PITA as you would have to attached to a PC configured for NVFlash feach time you wanted to backup and/or restore.
Update: I asked the question in the CWM thread. Will update when I hear anything.

Also, I don't that nvflash will restore the data partition. All the images that I have are blank!

To outline my situation, I have installed CWM to my phone, and flashed version 2.5.1.2 of Galaxy S i9000 (but the recovery boot doesn't show as CWM) on a Samsung InFuse 4G (this part I managed to find by scouring the forums) with Firmware version 2.2.1, Kernel 2.6.32.9, with Build FROYO.UCKH1. This is as far as I have gotten because I cannot seem to get a backup of my phone's ROM made. So, my question is can someone explain (without jargon, I haven't quite learned it yet) in simple steps how to resolve this issue and help me continue my way to flashing a custom ROM? I've checked and read so many other guides, but they are confusing because the steps aren't (sad to say) dumbed down for me. Here's an example of what I read:
1: dl CWM (actually had to go look this up and figure out what it was)
2: flash CWM (my phone model wasn't on the list, but after an extensive search found out that I could use the Galaxy S i9000 [supposedly])
3: boot into CWM Recovery (can't do it, for some reason it won't load on my phone.)
4: perform backup with CWM (as before, can't do it, read I could use Titanium backup but no depth was given)
5: dl a rom and place it on your sd card (this one is understood, short and to the point)
6: boot into CWM and flash rom
Unfortunately, when I start out on a new OS (already owning Windows and getting good at Linux) I tend to not even understand these so-called "Dummies Guides." I need something filled with minimal jargon that is short and sweet. Any information would be helpful
Also, I would like to know the likelihood of bricking my phone (based off of its specs) if it is possible to find out...
I'm a little bit confused here. How come you've flashed an i9000 (Galaxy S) firmware onto an Infuse? I think we can work out your backup problems though
I mean that I flashed the Galaxy S i9000 version of CWM Recovery to my phone because there wasn't an InFuse option. (according to one thread, it said that the i9000 version was compatible with the InFuse)
However, I flashed the Recovery, but when I booted into recovery mode, I was still in the stock recovery. Any explanation for this and everything else?
I don't really know anything about the Android system yet, but I hope to be good enough to become a developer one day.

Gotcha. Sounds like the recovery hasn't flashed properly. Did you have the phone rooted before flashing the recovery?
Here is an awesome thread with video guides on just about everything you could need. Here is another. I take it you've already followed at least one of these to get the recovery flashed, so it might pay to try the 3E recovery instead and see if that works.
You may need to go right back to stock and start over. If you do, AdamOutler has got you covered right here.
I'll stay subscribed in case you need anything else, best of luck mate
My phone was rooted with SuperOneClick. Superuser was still intact. I read on a thread that the CWM Recovery could "fake flash" and that it would still be accessible by selecting "boot into recovery" but it doesn't show.
It says 3E in my recovery mode, is that the modified or is it actually stock?
I downloaded CWM from the market (method 2) but for some reason have update.zip on my phone (method 1). Any explanation? I don't exactly remember downloading a .zip file...

It may have 'fake flashed' and not worked at all. Both stock and modified recovery will say 3E, the difference is in the version numbers although I can't picture them off the top of my head. If CWM had worked, you would not be seeing 3E, you would see the typical array of CWM options. The modified 3E does not give you the same options CWM does, it just gives you the option to flash an 'unsigned' image from Recovery.
I have never had any luck with ROM Manager personally, although a lot of people swear by it. I found it especially flaky flashing recoveries to any device, very hit-and-miss. I personally prefer, and recommend, flashing recoveries manually via ADB. A little trickier, but a lot more trustworthy.
That said, try flashing recovery through RM again before taking any further steps. Flashing a recovery over a recovery won't hurt
I've tried three separate times to install the CWM recovery, but all were unsuccessful. What's this about ADB? I remember seeing the ADB Daemon in the SuperOneClick rooting process. And how tricky is it exactly, does it require code?
I have the Titanium Backup app on my phone, and I have backed up all the system and app data, but they are all separate files instead of a single (what, .md5?) file. I remember reading another thread that said you could back up a ROM via TB but I can't find a back up ROM option. Is there a particular way to do this or do I have to have the Premium/Pro version of TB? Or have I pretty much done all I can do with TB?

ADB is a command-line interface between your PC and your phone. You enable USB debugging and connect the phone via USB to the computer. Once you have the correct drivers installed, you can then use ADB (part of the Android SDK available for download) to send commands to your phone, as well as push and pull files. This requires full root, which you already have.
For example you can grab the recovery.img for CWN on the Infuse and tell ADB to 'flash recovery recovery.img' and actually ensure it flashes.
There are some excellent ADB tutorials floating around, this one in particular got me started. Make sure you do a bit of reading first though: the wrong command can royally screw you.
After you're familiar, you should be able to use ADB to push a recovery to your phone, whether it be unsecured 3E, or CWM.
I'll stay subscribed for any queries you may have
How close is the ADB interface to other command-line interfaces like Linux or Windows? I use both operating systems on my laptop and I have familiarized myself with both of them (mostly). What am I supposed to be expecting when I use it? Also, I can't seem to find the recovery.img file, what folder would that be under?

Don't know about Linux, but ADB works through a Windows command prompt so its pretty much the same. You will need to have ADB, Fastboot plus whatever you wish to flash (recovery.img) in a 'working' directory, then run a command prompt from that directory.
You will probably need to download the recovery.img file.from XDA. It may be zipped up (they usually are).

I've successfully got ADB started in the command prompt (not that bad :]) but when I try to pull the directory map from my phone, it says: remote object "xxxxxxxxx" does not exist. And what's this about Fastboot? Edit: Did a bootloader command test, worked just fine. No success on pulling directory

I don't think that's the correct format to pull directory structure. I'll have to read up on that one
Fastboot is another tool you can use to flash bootloaders, radios, recoveries etc through the command prompt.

You're right, tried using the <remote> variable as a file instead of the device serial. Typed:
adb pull .. files
prompt skitzed out after that. I know it won't damage anything since it's a copy procedure but I'm looking for the file and it's not there. it said it's pulling everything after skipping "special files"
Edit: It just finished, said it couldn't create the file because for some reason it was trying to copy the files from the phone to the phone

Ooh good question. I don't think so, but I'm not sure. I know you can pull directories like /system/ and whatnot, but as for repackaging them into a working backup, that may be a bit more involved. I would use ADB to.push a working CWM and do it that way, but it sounds.like you're a bit better at the command-line stuff than I so you may be able to work it!

Although there is a way to make sure you have a backup, flash this file in cwm
sourceforge.net/projects/teamacid/files/fb/cwm/cm7-efs-backup.zip/download
And there will be two files in the root of your sd card
Efs-backup.tar and efs-backup.tar.md5 ( I suggest save it to your computer, it saved my ass )
And you can restore this backup at anytime by flashing this
sourceforge.net/projects/teamacid/files/fb/cwm/cm7-efs-restore.zip/download

Efs is the files system that holds the unique identifiers for your device. Without it, your phone is basically useless. You won't be able to connect to any network properly do things like phone calls, internet, texting, are all degraded, if they even work at all... Make sure you know what you are doing before messing with it. Fb created a vet good guide on the wiki. Follow it to a T!

I would suggest using a root browser to copy the EFS folder to somewhere safe on your PC and copy a 2nd back-up to your SD card. I lost IMEI going from CM7 to moKeeOS but was able to easliy restore it with a back-up and a root browser.
The flashable EFS back-up/restore from FB should still be used, but with EFS/IMEI I don't think you can be too careful and backing it up manually as previously stated is a good idea.
Yeah, I keep multiple copies of it on my PC. The reason being is that I copy it whenever I do a backup before a flash. So I have a directory with the date with 3 folders: efs, nandroid, and sdcard. I used adb to copy them:
Code:
cd efs
adb pull /efs/
Probably overkill, but better to be safe than sorry, eh?
Ok, but once you lose IMEI and don't have a backup (I received this phone for repair), then what can I do?

It's pretty much screwed without the OEM Samsung/Tmo software. You would have to send it to Samsung for repair, or you might get lucky and get an engineer to hook you up, but that is unlikely...

thanks for the answer. that OEM software isn't available in the forums or anywhere else for us? because I swear I flashed something OEM'ish without root with heimdall.
also, the imei is on the battery part of the phone, can't i fix it?
i read somewhere that you could use a phone just fine without imei on the about phone.
you can use the phone without imei, but it doesn't function as well as it would with it. Also, i was using titanium backup and it said my device's id was changed, and it showed my actual imei. If i were to restore it, would that fix the imei?
EFS help on the SGH-T959V
Basically, I've had a hell of a time with some EFS drama this weekend, made a total noob mistake, but in a stroke of luck I was able to "recover" so to speak my EFS even after it was supposedly "wiped."
After some thorough research and READING and bit of thought, I realized that the PIT mapping layouts between BML and MTD are indeed different, and that in theory if one remaps to BML (in layman's terms a stock partition map) then the EFS data originally on the phone gets correctly remapped (at least in my case it did).
To reiterate:
1. I did a nandroid backup. Basic ****. I hope to god you at least did this step too.
2. I used the cm7-efs-backup.zip script to backup my EFS. This was my first mistake. In my case, I don't know why I'm still researching, this script failed to make a backup .tar on my sdcard or anywhere else for that matter. It didn't throw any error messages either on the screen in the process. Not trying to attack the authors of that script, I'm just saying it didn't work for me this time.
3. I pushed the TWRP boot.img with Heimdall
4. I used the cm7-efs-restore.zip script which also "succeeded" but did nothing to restore any sort of EFS obviously because there was no backup to begin with.
5. I flashed R11 unofficial cm7 and booted up. Everything was fine but the IMEI was corrupted and I confirmed that the new MTD EFS partition was empty. On T-Mobile I could place no calls and only got sporadic and intermittent data access.
It was at this point I was sure I had ruined my phone.
After some more careful reading I realized that the original EFS was still present on the firmware, however the new MTD layout I flashed (wisely) stores its EFS partition in a different physical location. In theory, I thought if I reverted to BML and a stock ROM then I would recover the original EFS. In my case, this was successful.
1. I accessed the most recent "boot.img" file from my most recent nandroid and pushed that back to the device with Heimdall
2. At this point you have to flip your USB drivers back to USB Composite Device.
3. I then used a Heimdall one click to return to a rooted stock KJ6 "Gremlin Remover"
4. Upon restart, everything was fine (sigh of relief)
At this point, I'm still trying to determine why my EFS cannot be backed up with a few automatic tools. I made a backup of the file structure, but even lyriquidperfection's EFS Pro 1.4.7 can't make a backup of the EFS. It can access the ADB Server, but the backup 'fails'.
I'll check back in after I figure out why.
Hopefully this info will help anyone else who has switched to MTD and has a missing EFS.

I had similar issues yesterday. If your trying to install the twrp and then downgrade to the version with wifi dont flash the boot.img with heimdall. Follow the instructions for installing via cwm.
Just install the zip that has twrp in it. But follow the directions for normal cwm installation.
Also when trying to make a backup of your efs, make sure system is mounted. I initially did not have any problem but I was on antonx's kernel and when you flash with that recovery it would mount properly. What is happening is system isnt getting mounted. So its making a null backup.
The most important thing to do is when you are trying to make a backup of your efs is mount system!
Hi have you tried the updated EFS Pro v1.7.13? It can now automatically detect the mount point of the '/efs' folder for back up and restore. Also many many bug fixes and new code to communicate with adb.exe alot more quickly and efficiently.
Head over to the forum and check it out.
I already solved this problem, but this would seem useful other people with the same problem. But what forums are you exactly referring to?

As we now have functional recovery options on our tablets, and people will inevitably mess things up with their device, we need to get a way to get your tablets back to factory condition. But I need your help with this!
What do you want?
Here's my idea: We have all seen various ZIPs floating around, most of them leaked from somewhere. The problem with these is that you can't use OTA updates, and I'm not sure what Acer Service Center thinks of custom ROM installs. What I want is to build a list of software that is officially distributed by Acer, is OTA-updateable, etc. For this reason, I want people that have not yet modified their tablets (except root) to provide image dumps of their /system, /boot, /flexrom, and /recovery partition. It's really easy to do, and you'll help yourself and others when they get into trouble.
Can I help?
Answer all of the following questions. If at one point the answer is "Sorry, you can't help", well... You can't help
Is your device unlocked and rooted? Yes - You can help! / No - You can still help, but you need to unlock and root your device.
Do you have the original Acer ROM installed on your device? Yes - You can help! / No - Sorry, you can't help
Have you received the latest OTA updates for your device? Yes - You can help! / No - You can help as well!
Have you removed any apps or files from the /system or /flexrom partition? Yes - Sorry, you can't help / No - You can help!
Have you installed a custom recovery image? Yes - You can still help, as long as everything else is still original / No - You can help!
Okay, so I can help, now what?
If you can and are willing to help (remember, it could save your own ass one day), follow the instructions below. If you get stuck or simply don't know where to start but are willing to help, let us know in this thread and I'm sure we can all help eachother out.
This will not gather any personal data from you. Personal data is stored on the /data partition, which we don't need, so: No worries!
Root your device, if you haven't already.
Connect your tablet to your computer via ADB
Type the following command: adb shell. You are now logged into your tablet. You can exit at any time by typing exit and hitting ENTER.
Type the following command: dd if=/dev/block/mmcblk0p2 of=/sdcard/boot.img. This will copy your /boot partition to a file called boot.img on your internal storage. This one will be fast, it only has about 8MB to copy.
This step can be skipped if you have a custom recovery! Type the following command: dd if=/dev/block/mmcblk0p1 of=/sdcard/recovery.img. This will copy your /recovery partition to a file called recovery.img on your internal storage. This one will be fast as well, it only has about 6MB to copy.
Type the following command: dd if=/dev/block/mmcblk0p3 of=/sdcard/system.img. This will copy your /system partition to a file called system.img on your internal storage. This one will take a bit longer, it has about 360MB to copy.
Type the following command: dd if=/dev/block/mmcblk0p6 of=/sdcard/flexrom.img. This will copy your /flexrom partition to a file called flexrom.img on your internal storage. This one will take a bit longer as well, it has about 360MB to copy.
Type exit to exit the ADB shell. Copy the four .img files from your tablet (internal storage) to your computer. You might have to reboot your tablet if the files don't show up.
ZIP or RAR these files, and upload them somewhere. If you can't find a place to store them: send me a private message or reply in this thread and we'll arrange something else. If you have uploaded the files somewhere: again, send me a private message or reply in this thread.
So now what?
When I receive your files, I will package them into an update.zip that can be flashed from custom recoveries. This will then restore everything (including the custom recovery) to factory state, which can help you in getting your device back to stock.
What versions do you have already?
Acer_AV041_A510_1.044.00_WW_GEN1 (download links will follow shortly)
Acer_AV041_A510_1.098.00_EMEA_CUS1 (download links will follow shortly)
Acer_AV041_A510_1.099.00_EMEA_DE (download links will follow shortly)
The idea sounds great so far. But I have a small problem to make a complete backup for my a511.
Your linked root tutorial for the procedure is only for a100/a510 and doesn't work for a511, as I understand.
The tutorial for rooting the a511 needs first to flash a CWM.
http://forum.xda-developers.com/showthread.php?t=1729432
So it isn't possible for us to backup the recovery partition, right ?
I have the stock Acer_AV041_511_1.028.00_EMEA_DE on my device.
Is it even possible to backup and recover the baseband ?
I'm very interested in your CWM recovery for a511 too, but since many guys f++++d up their device now, I want to make sure that my device will not goes the same way.
i can help, n my tab is rooted.
but i don understand the first step: Connect your tablet to your computer via ADB
What about if we have removed system apps (such as the antivirus that comes with the tablet). It wouldn't be a complete dump if it didn't include those.
I have root and am happy to provide a dump, but I did uninstall several of the crappier pre-installed apps that came with my tablet.

Hi, your device will not brick, I can send you a test A511 recovery if you want. Worst that can happen is that recovery won't boot, but in that case you can simply put back recovery. Send me a private message and we can work something out.

Then it's of no use, unless you have a backup of your pre-installed apps. Removing apps from the /system or /flexrom partition is not recommended, and you gain nothing by it: You only gain space on read-only filesystems which you won't use in 99% of situations, and you've now broken OTA's for yourself as well, as OTA's will only install when apps are present unless you start modifying OTA files.
The 'correct' way to get rid of pre-installed apps is simply freezing them, either from the settings menu or with an app like Titanium Backup. This will make it seem like they're not there (so they don't use resources at all), but the APKs don't get removed.
So unfortunately, we can't use your dumps to restore devices to factory state. Unless, ofcourse, you've made a backup of the apps somewhere.

Do you have ADB or the Android SDK installed?

I just learned ADB, n successful install ur CWM, later will try to dump my stock Rom to u.
My stock Rom version 1.073 ww gen1
does it matter if the system apps have been frozen or do they need to be unfrozen first?
I have flashed that remove stock recovery mod so the stock rom doesn't keep overwriting cwm on reboot. Does that disqualify me? If not I'll dump my rom for you when I get home.
I'm on this rom version:
ro.build.pandora.id=Acer_AV041_A510_RV28RC04_PA_CUS1
ro.build.flexrom.id=Acer_AV041_A510_1.076.00_PA_CUS1
I unlocked bootloader,rooted,installed cwm then backed up my stock rom.Could i restore my stock rom then be able to send you those fills
and return to total stock.

i think he mean that the a511 recovery doesn't work properly....you can flash a zip, but nearly all other options brick the device
i have a a511 too with Acer_AV041_A511_1.028.00.EMEA_DE and can help with testing or something else
I have Acer AV041_A510_1.079.00_PA_CA. (Canada)
I have not done a thing to it because it is a replacement for the Galaxy Note I bricked trying to upgrade from GB to ICS, too early.
I might try again if I was sure I could get back to where I am, using your process.
I assume that your Root link is comprehensive but I also need reassurance on how to ADB.

No, as I understand, the only working methode to root the a511 is to bootloader unlock, flash the custom recovery and then the root.zip.
Maybe I'm wrong and there is another working way to root the device ?
The problem is simply, that we lost the stock recovery before we have a backup from it.
If we have another root way for a511, the backup of stock firmware is done in a few minutes and from this point we can test the a511 custom recovery from NoThrills.
To the A511 owners: Technically, if you have a install-recovery.sh file on your device, the device will always flash recovery back from the boot.img.
In theory: To test, one could simply overwrite the stock recovery with my Recovery (not the other ones, they will brick your device) and then when you reboot, your device will overwrite the recovery with the stock one again. So you really don't need a backup of the recovery partition.
As long as you don't let your device fully boot (so, stay in recovery) there's plenty of time to test if the recovery works or not. If it doesn't, simply reset your device and it will flash back the original recovery (again: provided there is a install-recovery.sh in your /system partition).
So again, if anyone is willing to test, let me know

I can't find a install-recovery.sh in /system partition on my a511. Search on root-explorer can't find one on the device.
Even NOT on /system/etc like on other devices.

Ah damn, I did back them up via titanium but it doesn't seem to want to restore them - it just sits there say restoring app.

Yeah, I meant /system/etc... That's weird, I'd figure Acer would use the same system on the A511... Let me check one of the leaked ROMs...
Hello,
I have an stock Acer_AV041_A510_1.098.00_EMEA_CUS1, there we go for the files
Host file is not the stock version, it was edited by AdAway.
Can you make a version without recovery overwritting ?
I thinks a lot of people want to try some roms... just for testing...
Acer_AV041_A510_1.098.00_EMEA_CUS1 boot && system && flexroom:

Yes you can if you install a custom recovery.
And once your recovery is installed, you can make a backup and this is complete image of your phone.
Except all of your data which are on your sdcard.
And I suppose that you have different guides in the S3 forum with all guidelines for install and use a recovery
So take a little bit of time and search, read and compare a little and when you are ready, you can install your recovery
custom recovery

Thank you for the help and so quick response.
I have search already on different forums about recovery but I read things like ADB, custom rom, flashing and so on....So I am afraid about doing something wrong which can break my phone. Till yesterday I haven't root my phone because of scare to do something wrong.
Then accident happened. My memory cheap break (without reason, nobody knows why). Samsung service change memory cheap (on warranty), but I have loose all my data. When I say data I mean my application with a few years data filled in (like t2expense, aCar....).So I have made search all over the net about rooting and making FULL (image) backup. Then I found the easiest way to root my phone with CF-Auto-root and that make me happy because was really quick and simple. I buy also Titanium backup and make full backup (all app, user+data). But then I read on different forum that Titanium backup isn't image backup and if I want to make complete image like backup I need nandroid backup.
So please don't be angry if I say that I don't understand what mean "install custom recovery" I want something like CF-Auto-root; simple !! Is there a simple way to do this "install custom recovery". I want to do this quick and simple without hassle. I don't have experience, and I not shame to say I am an idiot for the Android. Before my Galaxy S3 I have iPhone so, it is normal that I am afraid. I read so many about custom rom and all other thing that my head is full of android stuff. To much at the moment. I only want if there is possibility to make image of my phone (like True Image in windows)so if phone break I don't need to install all application again. I have try to search like you mentioned for the "install custom recovery" but I again find so many confusing info like for example bellow; So I am to afraid to do this without afraid that I will loose my data. If you can help me with some better way I will appreciate and I say thank you in advance.
One more time Thank you very much,
Slavko
