Is there a way to Backup and Restore Original Shipped Firmware? Is we have Norton Ghost for Android then it will be good...

The purpose is to claim the phone for warranty, after flashed with customized firmware. The phone's hardware might go fault.
[Galaxy S II Q&A, Help & Troubleshooting] drreality:
Well as a previous sgs user I know that the best way is to have root on ur device then u can access cwm to create a complete image (backup) of ur current os.

I don't know if there is a better way of doing so

[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
For an own backup, exactely as you bought the phone, here's what I did:

- flash an insecure kernel (stock kernels are available for all FWs, so restoring original stock kernel is easy)

- apply root

- dump all important partitions:

dd if=/dev/block/mmcblk0p1 of=/sdcard/p1-EFS.img bs=4096
dd if=/dev/block/mmcblk0p4 of=/sdcard/p4-PARAM.img bs=4096
dd if=/dev/block/mmcblk0p5 of=/sdcard/p5-KERNEL.img bs=4096
dd if=/dev/block/mmcblk0p8 of=/sdcard/p8-MODEM.img bs=4096
dd if=/dev/block/mmcblk0p9 of=/sdcard/p9-FACTORYFS.img bs=4096
dd if=/dev/block/mmcblk0p12 of=/sdcard/p12-HIDDEN.img bs=4096

As a more easy/convinient alternative you could flash a kernel with a custom recovery (like CF-Root, containing CWM recovery) and use the Nandroid backup feature from the recovery menu - but those root-kernels usually perform a few more changes on the /system partition, so I did my "initial stock backup" just using an insecure kernel and root applied.
[Galaxy S II Q&A, Help & Troubleshooting] techjunkieza:
Thanks for the advice! I have a question regarding Nandroid and CWM. Restoring the image made with Nandroid is easy enough, but won't the carrier/Samsung detect that a custom recovery (CWM) has been installed and consider it voiding the warranty regardless of the stock ROM being on the device?

Thanks in advance. :)
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
After restoring a stock backup via a custom recovery/nandroid, just flash a stock kernel afterwards with Odin as well.

That will restore kernel and the recovery back to stock too.

All that is then left from a rooting is two files and a few symlinks hidden in /system/xbin - unlikely they'll go and check that IMO.
[Galaxy S II Q&A, Help & Troubleshooting] techjunkieza:
Thanks dude. I was wondering how it is done. I did not know that flashing a stock kernel will make the recovery mode default as well. I'm new to Android so please forgive the noob questions.:o Surely there should be a list of files in a thread somewhere which indicates which files are modified when rooting the phone?

So I take it by restoring the original ROM, flashing a stock kernel (if you have a custom recovery mode or root access), removing the files and symlinks and resetting the ROM counter that the phone will be "stock" again?
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
He, I had to learn all this myself recently, the SGS2 is my first Android device as well :)

For the SGS2 the recovery mode is part of the main kernel (partition), so flashing a stock kernel replaces that as well.

AFAIK this a unique Samy thing, on the other Android devices the recovery actually resides on its own partition.

Depending on how you rooted it's just /system/xbin/su that gets replaced and /system/xbin/busybox that gets added.

Then all the symlinks busybox installs - not sure if busybox has an "uninstall" option to remove them, if not just dump all symlinks in /system/xbin, on stock FWs there are none in this dir.
[Galaxy S II Q&A, Help & Troubleshooting] techjunkieza:
Thanks a lot for the advice. I see many people asking the same questions but no one really gives them answers. I'm guessing it's betterfor it to be on two different partitions in terms of coupling. For noobs, the Samsung way is easier.

Great. Thanks. I would like to know what Android does on a low level in order to gain root access. I'm going to research that a bit.

Thanks very much for the info!
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
Well, once one knows what happens it's not that much magic that happens.

Basically, the stock su gets replaced with a custom one that actually has a way of allowing other user (IDs) to run as root, Superuser.apk is installed to maintain su's database of allowed (and disallowed) user IDs and last not least busybox is installed to gain some shell commands not available (or limited) on stock.

All that is done via an adb daemon (already) running with root perms - that's what the insecure kernels do, they simply let the adbd run with root perms (so the above things can be done).

Each app running has it's unique, own user ID it's running with, so root access/permissions can easiely be maintained that way.

I hope that was what you wanted to know :)
[Galaxy S II Q&A, Help & Troubleshooting] techjunkieza:
Basically, yes! You definitely deserve a thanks for all of this. I was looking for information of what you just described but couldn't find anything. Shot dude!
[Galaxy S II Q&A, Help & Troubleshooting] aks1447:
how to reset counter without the USB jig ?
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
You don't.

Best you can do is getting rid of the triangle by flashing a stock kernel, but to reset the counter you really need the USB jig.
[Galaxy S II Q&A, Help & Troubleshooting] gingingingin:
Great post! I cannot find a clear answer to these questions as well:

1. What is the location of the so called "boot loader" and how to make a backup? On Intel architecture it's on the first few sectors of the disk block device.

2. What is the location of the "ODIN mode/Download mode" application and how to make a backup? I suspect it may be in some read only memory and there is nothing to backup?

3. What is the location of the partition table? How to backup?

I want to understand the real/core/linux/android way of doing these, not just blindly running arbitrary tools.

Thanks in advance.

I already did it on my SII running ICS 4.0.3, worked great!..., but..., read the thread and cross your fingers... :cool:
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
1, 2 and 3: they are outside of the normal partitioned space / on hidden partiions (the bootloader partition is visible in ICS though) and you should not touch them.

Backing them up is useless as when the bootloaders are corrupted/broken, you'll have no way to restore them anyways as no bootloader == no boot to run anything, hence no restoring.

One is advised to leave them alone and not touch them - usually you can't access them anyways.

2: "Download Mode" is part of the secondary bootloader (partitions /dev/block/mmcblk0p2 and mmcblk0p3).

Hence the inability to access Download Mode when the bootloaders are broken.
[Galaxy S II Q&A, Help & Troubleshooting] gingingingin:
Does it mean that "Download Mode" can be corrupt by overwriting this secondary bootloader? What about the the primary one? Is this a sure way for "hard bricking"? I was always wondering is there a way to completely lock yourself out of SGS2, but could not get a conclusive answer in the forum. Or you can recover from any failure by having any single piece backed up?

What do update packages mean when they contain a bootloader update - is it primary or secondary bootloader, or both?

You didn't say about the location of the partition table, although it's quite often part of the updates to have a PIT file with a new layout?

And last but not least, what is the basic sequence to recover from a partition based raw backup, like the one we're discussing in the thread?

​

I grabbed my case using the coupon code shared in another thread (http://xdaforums.com/showthread.php?t=1138526) and wanted to share the pros and cons of the "official" case.

​

IT'S SOLID

It's not surviving a fall from a table, but to be thrown in a laptop bag or luggage, this thing will protect your tablet. The case is made of a hardened plastic with a textured surface. The edges turn a little bit tougher to hold your tablet in place. There's not a lot of give in the design -- if you knock on it, it's like a piece of wood, so it's not absorbing any impact if you happen to drop objects on top of it.

​

IT OPENS THE WRONG WAY

This may seem like picking at something small, but it seems to be a big mistake in the overall design -- Opening the cover puts the hinge at the top (camera, power button, volume buttons). This caused a few issues in my first few times of use. When closing the cover, it would inadvertently press the power button bringing up the Power Options. Also, and this is a much smaller issue, this places the front facing camera at the bottom when the case is opened and pitched for ease of use.

​

THE CUTOUTS ARE POINTLESS

The biggest surprise, especially after having the power button hit a few times in error, is that there's a cutout for the headphone jack and rear camera. The designers included a port to connect your headset while the case is closed, but there's no cutout or indent for the other buttons along the top. While a headphone jack may make sense while closed, a camera cutout doesn't. While this means you can use the camera while the case is opened, that also means holding your case and tablet like an open book to take a picture. Chances are, if you really want a picture that badly with your Tab, you'll remove it from the case at that point.

The lack of cutouts or indents for the power button is the only major issue with the case, but a big one, because you may open the case to find your screen wide awake for you.

​

IT'S CLASSY

Versus the rest of the potential cases for the 10.1, this seems to be the classiest. The case is solid, the branding puts the Galaxy Tab's logos up front but minimal and it keeps the slimline design in check.

​

MAGNETIC CLASP

While other cover/cases use a range of different tricks, this case keeps it minimal with a built in magnetic clasp. When you fold back the flap, it attracts to the back and holds itself closed. It's simple and keeps the weight and bulk down.

​

OVERALL, IT'S GOOD

It's a solid case that doesn't add bulk, protects the screen well and looks slick. The matted and textured surface doesn't show fingerprints. For a tablet that prides itself on it's slimline design, this case doesn't add much (if any) bulk in an effort to protect your slate. I'd recommend, but advise if you plan to open/close your cover often, the power button issue may become annoying.

[Galaxy Tab 10.1 Accessories] akarol:
I do wish it opened the other way as I have mine propped up mostly and I don't like it upside down. It also makes the camera basically unusable as you have to hold the back cover above it while video taping.

My main gripe, however, is the little flap stays loose when the case is opened. They could have added a stronger magnet there and have it stick to the back cover so it doesn't dangle around. Why didn't they do that?! Tsk tsk tsk...
[Galaxy Tab 10.1 Accessories] SkillFul:
thanks for sharing :)
[Galaxy Tab 10.1 Accessories] xavierdylan:
What is the weight of just the case? Thanks
[Galaxy Tab 10.1 Accessories] jeandujardin01:
i'd say about 250g
[Galaxy Tab 10.1 Accessories] xavierdylan:
Thanks mate. did you weigh it? 250g is quiet a bit 565g +250g = 815g = Xoom :p
[Galaxy Tab 10.1 Accessories] MisterEdF:
9.389 ounces ~ 2.7kg
[Galaxy Tab 10.1 Accessories] jeandujardin01:
didnt weight it but the whole package is 400g according to expansys and another source

seeing the tons of plastic of the package i'd say 250g or less

to me this Book cover is the best case for the tab, best thing about it is that it always stays clean (no dirt stick to it, and it doest becomes ashy even though its black)

9.389 ounces = ~266g
[Galaxy Tab 10.1 Accessories] jaoropez:
i recently bought this case, really nice, and i agree with all your negative points. I read somewhere else that using a screen cover/sheild will interfere with the case, is anyone using a screen protector with this case? and if so which one, thanks!
[Galaxy Tab 10.1 Accessories] jamesrdorn:
I am using the ZAGG InvisiShield with the tab, works well but it has a plastic/rubber feel to it that you have to get used to. It's glossy, but overall it's nice.
[Galaxy Tab 10.1 Accessories] akarol:
The case itself might stay clean, but the screen of the tablet, which is the most important, doesn't. I feel that having the part of the lid that makes contact with the screen as a base is just a bad idea.
[Galaxy Tab 10.1 Accessories] SiL3nTKiLL:
i actually just got the case, and i dont midn it too much, a bit inconvenient to take pics tho and i wish it had a spot to store the stylus lol
[Galaxy Tab 10.1 Accessories] Maui:
Don't know why everyone wants screen protectors...the GalaxyTab uses Corning's GorillaGlass and should be safe against most scratching.
[Galaxy Tab 10.1 Accessories] akarol:
I'm not worrying about getting it scratched. I'm just annoyed at the dirt it collects from whatever surface it was opened on.
[Galaxy Tab 10.1 Accessories] pdxrealtor:
I have the case and I'm not super impressed. I actually ordered a pyro skin case and its on its way. I like the slim form factor of the oem, but the stand options aren't that great in some situations.

I've yet to make my mind up....maybe I'll keep both.
[Galaxy Tab 10.1 Accessories] jeandujardin01:
fingerprints !!! they kill me ! :)
[Galaxy Tab 10.1 Accessories] djchad72:
I really like mine. I have the leather pouch, which will work great when I travel with keyboard dock for a light mobile work station.

I then will use this case when ill be more mobile or supplementing along side my work laptop. If you don't need camera hole, I think you can simply put tab in upside down compared to the camera cutout. Then you can leave screen auto rotate off. But the nice thing about the as is fit is the port for charging is on top. So you don't have to worry about the cable and port being pressed in awkwardly against surface.
[Galaxy Tab 10.1 Accessories] jaoropez:
I received the case yesterday and so far it is OK. I the best thing about it is the sleek factor. Othe than that, but like people have mentioned it will not provide any fall protection. This is mainly to keep it safe while transporting it in your backpack. One thing that really bothers me is the chose they made for which side will be up and down. Right now up is the side with the headphone jack and there is a hole there for it. Now if you have headphones plugged in, then you have to unplug the headphones before you can open the tab and vice versa you have unplug it to Close it again.

The easy solution is to flip it upside down, still very dumb design choices by Samsung
[Galaxy Tab 10.1 Accessories] djchad72:
OK. I have used it more today and keep opening up to find the tablet is off. Anyone having this issue?
[Galaxy Tab 10.1 Accessories] just4747:
This case if awful in many ways:

The orientation is wrong when in landscape (camera should be at top when standing up on table using case flap).

It is SO hard to take pics with the case on..you have to hold the device with one hand and hold the flap up so it doesn't block the cam at the same time..so stupid.

You have to constantly keep moving the flap out of the way and keep it held against the case when it is flipped open to use the Tab. Why in God's name would they make it so that the flap isn't somehow held out of the way? Like another magnet or a magnetic clasp something...

The flap used as a stand never stays against the "groove" in the case..it's always whipping back out, making it almost useless as a support...nice freakin design.

You can accidentally press the power button even when the case is closed...if you push down on the "hinge" area, it is soft enough to easily press the button underneath.

The worst though is that like someone said, when the case is closed, covering the screen..somehow that I just don't get, there is tons of white dust-like stuff making it's way under the cover, onto the screen. Every single time I close the thing and had the case and screen pefectly clean, I will reopen the case after a while and all this white dust stuff is all over the screen again. If you continue using this case I guarantee you will get more dust in the device and under the screen.

Screw this expensive case (the only thing I like is the finish/feeling of it and the size/slimness- which is too bad considering the flaws), I now use the smoke version of this:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200624247046&ssPageName=STRK:MEWNX:IT and it is freakin awesome. So much better than the book case despite not having a cover.

Now I am stuck with a $60 case that I don't want and I'm too lazy to go setup a page to sell it on eBay or something or to return it to Samsung lol
[Galaxy Tab 10.1 Accessories] aygriffith:
About 25% of the time and especially after its been bouncing around in my bag, I find that its turned itself off while in the bookcase cover.
[Galaxy Tab 10.1 Accessories] akarol:
Goddamn, I've been trying to get a hold of the department responsible for refunds for this f'ing book cover case for hours now and they keep transferring me to different numbers. This is ridiculous! It took only one try to get it done when I returned something for my first Galaxy Tab. Annoying!

PS - The number given on the shipment e-mail is not valid anymore. =/
[Galaxy Tab 10.1 Accessories] djchad72:
I called Samsung and the lady 1) didnt know of a way to have a 2 step process to power off, where the power button solely could not turn it off, and 2) didnt know of anyone else having this issue.

I told her... $60 for a case... It shouldnt power off your tablet every time you walk from A to B. I guess I just have to try and carry it with the flap down around my hands, and not the other way around.

Completely idiotic. Surely they tried carrying it around from point A to B and found that average size hands are going to gravitate toward the power button at some point.

Very frusterating.
[Galaxy Tab 10.1 Accessories] akarol:
Guys, put the tablet upside down on the case and you're golden. How it was meant to be. You'll lose your camera, but who uses that on a tablet anyways?!
[Galaxy Tab 10.1 Accessories] jaoropez:
i totally agree, camera isnt taht great, just use your phones...still though i am pissed that I cant use the camera if i wanted too without have to hold that flap.

that TPU Case Cover for Samsung Galaxy Tab 10.1 P7510 Smoke that someone suggested looks promising...and only $10
[Galaxy Tab 10.1 Accessories] djchad72:
Yes. I know we cam do that or not hold it flap up. But for a $60 case should nor have to redesign it ourselves.

[Galaxy Tab 10.1 Accessories] Jake-CT:
Wow I actually quite like the book cover but I do see your points. Main issue for me is the weight of it but haven't experienced any of the powering off and white fluff mentioned here. Also I like how it stands up - seems to work well and you can make a good angle for typing if you flip it the other way around (if your tab is in it as samsung intended).
[Galaxy Tab 10.1 Accessories] Raistlin1:
I was playing aroudn with this case in the store and it is a great feeling case, I love the material. But the limited positions do suck, just typing or the one position for standing it up. I was able to give the tab a bit more of an angle but then the case doesn't support itself and it could slip causing it to fall down.

I really don't know what I want to do for a case, they all have many negatives so far. But as for fit and finish the Samsung case is the best hands down.
[Galaxy Tab 10.1 Accessories] just4747:
Still for sale, anyone?! Need this gone I need the money ASAP!

[Galaxy Tab 10.1 Accessories] Thor S:
I bought the case, 'cause it was the only one JR in New York did sell. I really love the material. Overall it is a nice protection for our tab, but with basically major fails in the design i'm really considering buying a new one. Seriously, what where Samsung thinking about making it upside down? How on earth can they be that stupid? Didn't they try it on, before they thought it is perfect?

Despite this major failure with the design, I'm still using it but still considering buying a new one, but no idea which one.
[Galaxy Tab 10.1 Accessories] silverball.slayer:
To make it 'not upside down' would require another fold of material like other folio cases (3 folds instead of 2) and make the case thicker.

[Galaxy Tab 10.1 Accessories] akarol:
Just returned mine to Samsung. After using Vipertech's case for a week, I just can't go back to the Samsung one. It's slim and all, but I'm so over the upside-down problem and the fact that every time I close it all the dust from the table is on the screen. =/
[Galaxy Tab 10.1 Accessories] akarol:
Or you could have the folding edge on the other end of the case, opposite of the camera's end. As it is shown in CNET and other photo reviews.
[Galaxy Tab 10.1 Accessories] cooljonL:
I'm getting one of these free with my GT tomorrow (if it arrives!)

It's better than nothing by the looks of it until the official BT Keyboard case is available.
