[Q] How to clone a SM-T700 ROM to desktop - Galaxy Tab S Q&A, Help & Troubleshooting

Hello XDA forums,
It's been a while since I've last logged onto my account and have asked you guys for some help (which has always been excellent and top notch).
I've been looking for some answers to this question for quite some time now and I need your help since my Google/XDA searches have come up empty handed. I've also reached out to the r/android IRC and they've suggested for me to use MDM system which I'm not willing to pay for at this stage in the small business I work for. I would like to apologize in advanced for using any terms incorrectly. Please don't hesitate to correct me.
So onto my question now: I would to create a ROM to be able to flash to other SM-T700 devices right out of the box (no root, no voiding warranty, etc etc). This ROM would have a home screen with specifically installed apps and widgets, and a few security settings enabled. I imagined setting up one of my tablets and somehow "cloning/back up" that ROM to my desktop to be flashed (using anything; ODIN, SDB, fastboot, or heimdall) onto other SM-T700 devices right out of the box.
Is this possible? Am I making sense?

Not w/o voiding the warranty / unlooking IMO. Otherwise just use Nandroid.

Unlocking IMO?
Would I be voiding the warranty for all devices or just the one I'll be using to clone the ROM?
Thanks for taking the time to reply to my message.

All devices, you can't install the needed custom recovery for both backup and restore w/o voiding the warranty.
If you consider unlocking to void the warranty (you normally do). There are different opinions on that (also depending on where you live).

Are su/sudo available in android, can root be performed without rom flash?

Hello guys, seem like I will be moving to this part of xda in a couple of weeks
I have several questions though, mostly regarding roms and rooting. I have used linux for sometime and from what I understand su/sudo/gksu/gksudo etc. are not available in android? I mean I cannot gain root access in the same way as on the desktop. And if I root the device it will not lose warranty, as I can unroot it later on similar to SPL/HardSPL in winmo. The other question is, I think I am going to be OK with the stock rom, as the desire is some pretty fast hardware, so can I root it without installing rooted rom, again as HardSPL in winmo. I will probably need the root access for some applications, like task manager, otherwise I will probably only use the phone, browser, mp3, social stuff, gps, email, videos like I did in the past.
I am sorry if these questions were asked before, I read the tutorials in the first post, however things are still not quite clear for me
You don't have to install a custom ROM if you use unrevoked for root, it just adds the superuser app to your current ROM. However it will flash the recovery, so it voids your warranty anyway. There is no way to avoid this.
No idea about su/sudo though, I know nothing about linux
Well,I kinda have the same questions...First off,there is the su command in Android which is equal to the sudo command in Ubuntu etc.To give an example,I was trying out the ezHero rom on my Hero the other day and jit was enabled with this process:in terminal emulator you type in su,and then it asks for superuser permissions(probably only available through root?) and then you type jit-on and some other things happen that don't really matter here.I believe I answered half your question.Now,if root can be achieved through terminal...I don't think so!It's above my head though...
Thanks guys, that cleared up a lot
About this recovery, I guess if I can unroot and flash "stock recovery" if there is such a thing, it will not be a problem, is this the case? If I can't maybe I should buy a used device instead of a new one.
About the su/sudo, I have used mostly Ubuntu, and in the users menu I usually had 2 users - admin and root, once I set up a root password. Then I used the admin user and if I needed root access for something I did it with su or sudo + <command>, requiring password, or if it was software launcher requiring root access with a path gksudo + <regular parameters/command> in the launcher properties. For example, as far as I know you cannot change attributes like readable/writeable or edit files which are not personally belonging to your user without root access . It is a really neat and simple feature on the desktop and I am puzzled as to why they removed it from the stock rom. I didn't include this in the original post so that it is not too confusing.
Anyway thanks guys, having been with winmo for the last few years, I will finally give android a go and see if it works for me
Yeah it is relatively easy to flash to complete stock ROM and recovery. There's a guide somewhere in the developer board.

No. Just no.
There's nothing in the warranty agreement to suggest that (there is a line that confirms that in the N1 agreement, though), and countless people have sent their rooted Desires back to HTC for repairs, and they've all been repaired. They just won't repair it if the ROM you flashed broke some hardware (ie overheated the LED and made it short-circuit).
Thanks guys, then I'll get a new device, great

[Q] Are there any downsides to rooting ?

Hi all, I've done a fair bit of searching and reading up but not sure I can find definitive answers to whether there are any downsides to rooting my One X.
I am thinking similar to tethered jailbreaks in the iOS world, where if you run out of juice you have to cable up to get it to boot up etc.
I would like to root, so I have the freedom to use a few of the tweaks and mods on xda (such as the tweak to change the default - read too high - auto brightness levels), not sure I will actually replace my entire rom at this stage, just root so I can use some of these minor tweaks.
so, is there anything that I need to genuinely consider before making the leap, some specific questions that spring to mind are;
1. Can I always easily revert it ?
2. Read some posts where people are struggling to charge once it hits 0% ? Is this an actual problem if I just root ? I do not want to brick a phone or have to prize open the case to take batteries out etc
3. If I chose to replace ROM's in the future, are there actual apps that more or less backup all your apps and settings so you can just reload that one app after a new ROM is installed, restore a backup and I am good to go, or do you have to manually setup everything from scratch again ?
Thanks for any advice you guys can offer.

The only downside to rooting is you get hooked on flashing. It's very easy to get back to stock. As long as you have proper RUU for your region that goes with your CID and all is fine.
At present, the only rooting method involves unlocking the bootloader. It can be locked again. But it's 'relocked' rather than 'locked'. So your warranty is still void in some cases.
I'm waiting for root method which doesn't require an unlocked bootloader. Or non HTCDEV Unlocked bootloader and S-OFF before I do mine, but that's just me

HTC will only refuse your warranty if you balls up your phone as a result of flashing roms. Everything else such as hardware defects will leave the warranty in tact.

Should I root?

Hi guys,
I have samsung note 2 N7100
Android version 4.1.2
I am just looking around and I see loads of stuff about rooting, I came from Apple iPhones coz they are **** now lol and i have jailbroken all my devices. Had my note 2 for few months now but I am worried if i root it I will loose my warranty and might mess up my phone....
I seen the tutorials and it looks really easy but lets say down the line I want to un-root my device, could I leave no trace of the device being rooted?
I had to replace my old note 2 and it was rooted i managed to un root it but the benefit was that I work in the phone shop and I replaced it.
SHOULD I ROOT THE DEVICE?
WHAT BENEFITS WILL I GET?
Cheers guy
p.s. love the community here!
Hi,
Even without root, the Note 2 is still beast.
But with all these customizations, tweaks, improvement going on in the development threads, it's a GO.
Plus, you can unroot easily anytime you have a computer.
Cheers!
First of all! Welcome to the family
Well here's what! Rooting your device is basically allowing your phone to run apps and do special operations that it cannot normally do and also flash custom roms. If anyone else can help with a reply that will be awesome. Just go through the step by step process in either this link: http://forum.xda-developers.com/showthread.php?t=1896696 or this one: http://forum.xda-developers.com/showthread.php?t=1923956.
For more understanding, watch videos on youtube on the terms: rooting, custom Rom and custom recovery. If anyone can help it would be appreciated!

It's easy to remove all evidence of rooting if you ever need to. Still I don't think you should rush into it if your uncertain. There are benefits I've gained from rooting though nothing I couldn't live without. To some extent I've been rooting for so long it's just a habit now, I'm just used to having it, but even if I didn't have it on this phone I'd be happy with it.

If you know valid reason to root your device then root it, don't rush for fun or experiments. when you find some stuffs needs root that is must for you then go and root, but read couple of times before it.

Me neither. However it's a fact that a small number of units shipped will develop a fault. If you're going to put big money into a phone line the Note 2 then it's not unnatural to want assurance that you are going to have protection if you are one of the unlucky ones.

Warranty is always a question of time.
The advantage of rooting is difficult to explain to everyone who is doubting about that.
For me rooting is something that should not be necessary.
There are many users that will never use root access even when it is available.
But there are thoughts that root access will lead to problems or misuse.
For me root access is usefull in some cases. For example to install Whatsapp on tablets with wifi-only.
Not a question of advantages and disadvantages of Root OR how it is helpful
I mean to say You can claim warranty even you have device rooted with flash counter 0.
2 main reasons for me :
- Blocking ads
- backing up my entire phone.
You can't do that without root.
Now that my phone is rooted i've done other changes like installing the aosp camera to use photosphere and CWM to backup and install zip easier.
But I keep stock rom with stock kernel, with this phone there is no need to change it to my mind.
With root you can put any tiers application in the multi windows right?
You can also disable bloatware or freeze them with greenify.
The only thing is missing with is the undervolt settings. That's why I'm already in custom kernel/ROM.
But when 4.2.2 goes out I'll certainly go back stock ROM which i hope, will increase battery life.

Not in the good ole United States of America (but there is more too this?)
If you purchase a Samsung Galaxy Note II (or any other phone) from a Authorized Dealer, it comes with one year warranty and guarteneed warranty per terms of that dealers contract. If you unlock/root/flash, whatever, you break that contract because of something YOU did, not the Authorized Dealer, therefore, they are not responsible for it, YOU are.
Now, as someone that has unlocked/rooted/flashed MANY phones over the years, every set of instructions I have every read.....1. Explains the above first. 2. Immediately explains to read ALL the instructions first and understand them before you attempt anything. 3. Explains THEY are not responsible if you brick your phone. 4. They always give detailed instructions (or link to them) a. How to put it back to stock and b. Lastly, DO NOT TAKE PHONE BACK TO DEALER ROOTED!!!
Now, with that said, I (we) in America have T.E.P. (Total Equiptment Protection) that I pay $11.00USD a month. This insurance is in case I lose my phone, its stolen, I drop in bathtub, run over with car.............I pay a deductible ($150.00USD I think) and they give me a new phone.
Now, these are two different things. During the initial warranty period, If I have SDS, I take it back to Authorized Dealer, fix my s**t! After Warranty, period, I send it back to insurance company, pay deductible, and either they send you a new one OR send you a agreed upon compatable device!
Cheers!!!
For me rooting was a must for directory bind. As has been said blocking ads is essential greenify good and the increase Volume mod was also a god send.
However on the downside I've lost sky go.
I rooted my Samsung day 2 and wouldn't turn back. Iv undervolted getting 2 days out of my battery. Root is awesome.

Can I root and keep everything stock and get ota updates? That would be perfect because I really dislike custom roms. I've got the 4G version.

New to Rooting.

I've been rooting since OG Evo days, but only played with that, the s2, and s3. Rooting was easy as pie. But with all this knox stuff I'm wary.
I recently read reports of people sending in their phones to both Samsung and tmobile and getting it back with knox restored but still maintaining sim unlocks. So obviously it's a well kept firmware they flash or perhaps signatures.
This in mind I used kingoapp, and root was easy. Just decline the recovery install and you'll maintain 0x0. But after this new information I'm still worried to trip knox for fear those restores we're just a fluke.
Anybody have luck with safestrap? I heard/read it doesn't replace recovery so it also won't trip knox? Also, as long as I don't flash kernels or recovery I'll be good right? Like i can delete bloat or install at root level to /system and I'll be fine?

First off, the above poster is wrong... can't believe he asks for a thank. When you install a custom recovery, that is when you trip Knox. There a method to install a custom ROM w/o a recovery using Mobile Odin Pro. I know nothing about that but have read here that it works. You just can't flash custom kernel. I went ahead and flash a custom recovery because I don't care about Knox and will never send this phone to Samsung for warranty repair.

Just the fact most of us have insurance plans; if we discover a problem such as faulty gps or screen displacement, etc, tmobile fixes it for us anyway, right?
So it really doesn't matter if we trip knox, correct???

I guess I shouldn't bother with safestrap then. Was planning on trying to pay off the note 3 and keep it anyway instead of jumping again this year.
Either way it won't matter...until I do eventually get a new handset but even then I know enough about rooting I shouldn't need to repair this one once paid off and detached from my account.
my next question is then should I TWRP or cwm? I tried CWM for the first time since gingerbread on my s3 and fell in love with it

Hey Nature! just wanted to add my 0.02, ok theres a difference between rooting, and a difference between flashing recoveries,kernels,roms,and what have you.
ill give a brief explanation in the differences. The Colors of the titles indicate how safe/dangerous it is to modify one of these things and wether it will void your warranty, Green=Wont void your warranty, and easily reversible. Orange=Void Warranty, Reversible, But starting to get Dangerous, Red=Definitely VVoids Warranty, and if screwed up, could ruin/brick your devvice Definitely Voids Warranty, and if screwed up, could ruin/brick your devvice
Rooting: When you are rooting your device, you are basically forcing your stock version of android to allow you (the user) root access, therefore allowing you to bypass/allow signature verification for apps, now this could be anything from homebrew apps that you are making yourself...to the naughty pirated apps, and i dont encourage the latter. By giving yourself root access to your phone, your allowing the next to happen:
Flashing a Custom Recovery: Ok ill explain this as simple as i can...Mostly all if not ALL android phones have a stock recovery, this is a safeguard in case some kind of software fault happened in the phone(stock software fault or what have you). Flashing a custom recovery would be your next step after Rooting a device (IF) you want to go further than apps, meaning Kernels, Roms etc. Now the reason you must Root your device in order to install a custom recovery, is because like explained above signature verification....Now this is when you begin to tread in warranty territory, once flashing a custom recovery...your warranty has become VOID, however what the custom recovery allows you to do is a multitude of things, but the most major is Flashing .ZIP files, which most roms are in the form of, now not only Roms are in ZIP files, so are kernels,mods,baseband firmwares, etc, with that being said, different phones/devices use different methods of flashing roms, lets say for example you somehow screwed something up on a samsung really bad, and it wont boot, however, you can still get into download mode...then you're safe, because samsung uses Odin to flash the entire phone back to stock meaning Recovery/aBoot/Data/System and bring you right back, but if you hard brick it, theres only 3 ways out from that...and they all suck....number one, is call me and send it to me to Jtag it for you ..but it takes long and its not that cheap, #2, Desolder the chip (whichever it is on the device that has caused the problem) and replace it...and thats not an easy task at all, ive done it once to an S3 successfully, after that i never wanted to do it again, and this was back when they were really expensive, and lastly....#3.....and this one is the worse....go buy a new one SO BE CAREFUL!
ROMS: So now that we have a custom recovery, a rom is basically a heavily modified version of Android! and let me tell ya, i love them...i love so many of them, there are sooo many different things that you can do with roms, but the most desired from what ive gathered, is so people can remove the bloatware that comes with their phone when they buy it from the carrier/manufacturer. Thats not all tho, there is way too much to get into, but some roms allow you to Overclock your phones CPU/GPU, and change the Behaviors of the phones hardware, and the major component in roms that allows that is the Kernel.
Kernel: Now dont totally quote me here, im still learning kernels, but a kernel is basically the binary software in the phone, almost like a bios that when modified from stock, changes the behavior of the MOST of the hardware, not all. Now i could be wrong and anyone please feel free to correct me, now i do want to give you a shot of my own advice here...if you dont know what you are doing, kernels are dangerous to a noobie..before i started messing with roms and kernels, i tried to get the best understanding i could, and ill be honest with you, i blew up a couple S3's doing so. but im still learning. so if you're unweary or still not educated enough in the hobby to get too it, please read more up on it, because as none of these guys here that are devs nor people like myself that are trying to help intend to destroy your device on you, so please be careful for your own device's safety, and to save yourself money and a broken heart.
Knox: Ok now correct me if im wrong here, because im still learning as this is new to me, i only saw it on the MJA bootloader on the S4 on Jellybean from Sprint when they first OTA'd it, but knox looks to be Samsungs pathetic try of not lettings us Access the devices binary software, like an encryption, or to only let us access and modify certain things, also samsung has added a flash counter, which will tell them how many times you have flashed a new rom, however there are ways around these things, google and the search bar are you best friends to start, and we can help too.
I Hope this helped and shed some light on some information, and please if anyone has anything to add or to correct me if im wrong anywhere please do so ^_^
P.S. To be totally honest, theres always a way to restore your device and even get the flash counter back to 0 again and put everything back to normal, if an experienced tech looks at it and puts it in download mode unless all is restored, hell be able to see everything, but honestly, if you pay off the phone, you havve nothing to worry about, but then again, i dont care much for warranties, so it all depends on how savvy with fixing problems when they go wrong, but if you ever need i can help you, im pretty experienced when it comes to everything but developing atm, i was a microelectronics major in college, so my expertise is mainly in hardware i.e. if you hard/soft brick the devvice i can usually get it out of that.
please excuse my typing, i type extremely fast, and i have a mechanical keyboard and i think some lettings are startings to give way such as the V key.

Oh and please i Highly suggest using Philz Touch!
Code:
http://goo.im/devs/philz_touch/CWM_Advanced_Edition/hltetmo
Thats for the HLTETMO version, which is our versions in this forum, all credit to phil ofcourse, it is basically CWM, but so much more user friendly and advanced with much more options, there are two files there, you obviously want the latest version, and there are two ways to do it, if you download the tar.md5 you must use Odin, and put your phone in download/odin mode, very easily done (turn it off unplug usb and press Home+Vol Dwn+Pwr) then once the screen pops up press Vol Up and then plug the USB in, and follow the instructions of w/e tutorial you are ready, but be very careful in odin mode, if you disturb the phone while its flashing you will most likely brick it, and the .zip is considering you already have a custom recovery and you can just flash it through there.

Now i could be wrong and anyone please feel free to correct me, now i do want to give you a shot of my own advice here...if you dont know what you are doing, kernels are dangerous to a noobie..before i started messing with roms and kernels, i tried to get the best understanding i could, and ill be honest with you, i blew up a couple S3's doing so. but im still learning. so if you're unweary or still not educated enough in the hobby to get too it, please read more up on it, because as none of these guys here that are devs nor people like myself that are trying to help intend to destroy your device on you, so please be careful for your own device's safety, and to save yourself money and a broken heart.
Knox: Ok now correct me if im wrong here, because im still learning as this is new to me, i only saw it on the MJA bootloader on the S4 on Jellybean from Sprint when they first OTA'd it, but knox looks to be Samsungs pathetic try of not lettings us Access the devices binary software, like an encryption, or to only let us access and modify certain things, also samsung has added a flash counter, which will tell them how many times you have flashed a new rom, however there are ways around these things, google and the search bar are you best friends to start, and we can help too.
I Hope this helped and shed some light on some information, and please if anyone has anything to add or to correct me if im wrong anywhere please do so ^_^
P.S. To be totally honest, theres always a way to restore your device and even get the flash counter back to 0 again and put everything back to normal, if an experienced tech looks at it and puts it in download mode unless all is restored, hell be able to see everything, but honestly, if you pay off the phone, you havve nothing to worry about, but then again, i dont care much for warranties, so it all depends on how savvy with fixing problems when they go wrong, but if you ever need i can help you, im pretty experienced when it comes to everything but developing atm, i was a microelectronics major in college, so my expertise is mainly in hardware i.e. if you hard/soft brick the devvice i can usually get it out of that.
please excuse my typing, i type extremely fast, and i have a mechanical keyboard and i think some lettings are startings to give way such as the V key.

Oh and please i Highly suggest using Philz Touch!
Code:
http://goo.im/devs/philz_touch/CWM_Advanced_Edition/hltetmo
Thats for the HLTETMO version, which is our versions in this forum, all credit to phil ofcourse, it is basically CWM, but so much more user friendly and advanced with much more options, there are two files there, you obviously want the latest version, and there are two ways to do it, if you download the tar.md5 you must use Odin, and put your phone in download/odin mode, very easily done (turn it off unplug usb and press Home+Vol Dwn+Pwr) then once the screen pops up press Vol Up and then plug the USB in, and follow the instructions of w/e tutorial you are ready, but be very careful in odin mode, if you disturb the phone while its flashing you will most likely brick it, and the .zip is considering you already have a custom recovery and you can just flash it through there.

Ty for the explanation. Unfortunately, that is if you took the time to write that or just copied, I knew most if not all of the risks. As I said earlier I've been rooting since gingerbread.
However, it's quite informative and anybody else who is new to rooting shall find it helpful.
Kernels are more or less a bios, if you will. But they are specific to builds. You can't use aosp on tw and vice versa. There are other key features but I can't remember off the top of my head. Basically no kernel =/= no phone or no features such as camera.
You're right about the s4, but if I'm not mistaken it was believed to be an eFuse, as was for the note 3 too. Although other members have said they got it back reset, 0x0, and sim unlocks intact to fix other issues like broken gps. Therefore it is believed to be software at a signature level.
And I'll look into philz, loved it on the s3. If you ever have q's about root feel free to pm me

He's not wrong. There are a couple different methods of rooting that don't require a custom recovery, therefore don't trip Knox.

Losing features upon bootloader unlock/root?

Hey everyone,
I've tried to google around and search the forums on XDA but there is no straight up answer to some questions I have. This is the first HTC device I own and although I have been rooting/unlocking devices since the Nexus 4, I am afraid to go ahead with this one. I just wanted the answers to the following questions, if anyone here knows them please:
1. Unlocking the bootloader seems straight-forward and supported by HTC. I'm in the UK which means no Uh-Oh protection. If something was to happen to the device and I sent it back under warranty, would I be ****ed or would HTC replace/repair it? HTC UK's call center was worse than useless and HTC US' policy doesn't apply to us so I thought I should ask here.
2. Does unlocking the bootloader and rooting mean I will lose access to the fingerprint scanner, camera quality or anything 'stock'? I know Android Pay won't work but at the moment I am not too bothered either way because it's a hit and miss thing with it.
3. Finally, is there a way to completely revert unlocking the phone/s-off and going back to S-ON/Locked without any signs of having messed around with the device? I ask in relation to question 1. If unlocking the bootloader voids the warranty for UK users, is there a way to go back to stock and make the phone as though NOTHING was done to it?
Thank you to anyone who helps answer even 1 of these questions :victory:. I want to root and get xposed onto my new device but not at the cost of losing features on a brand new phone or losing warranty on it either :silly:
1. I can't comment on this simply because I don't know and don't want to spread false information.
2. You will not lose any features at all. In fact, I'm running a bootloader unlocked and rooted setup and Android Pay still seems to work fine for me. It let me add a debit card but I haven't yet been able to actually try to purchase something.
3. Yes, if you are S-Off you can completely revert back to a locked bootloader with S-On if you want to.
I'd recommend both unlocking and S-Off so you can revert back to stock in the future for a warranty claim just to be safe.

Hey, thanks for the reply! Only just saw this, not sure why it didn't notify me.
Right no worries about point one seeing as point 3 makes it irrelevant if I can revert back and save my warranty anyway. Just to be sure on points 2 and 3, I can definitely 100% go back to Locked/S-On status and the system won't show I have messed around at all? As for Android Pay, that's cool! Did you set it up before or after rooting? And does your fingerprint scanner work? Can you make payments on google play by authorising with your fingerprint?
Thank you again for your help!

Yep, you can definitely 100% go back to Locked/S-On state assuming you were previously S-Off. There will be no signs that the device was messed with.
For Android Pay, I had initially set it up prior to rooting but the rooting process wiped my phone. I had no issues setting it up again on a freshly rooted install.
Google Play and every other app that uses it still fully supports authorization via fingerprint. From what I can tell, I have lost absolutely no features by rooting. There really is nothing to lose once you get past the initial phone wipe that occurs when you unlock the bootloader.

Ah that's great! Would've thought HTC would implement some kind of security thing where rooting may cause the fingerprint scanner to not work like Samsung/Sony have. Good on HTC :highfive: I'm gonna start reading up now and unlock/s-off/root the phone in the next few hours! :fingers-crossed:

Yeah, it really is a great thing they've done! HTC is being really friendly to developers and power users. If you have questions or need some help with the unlocking or rooting feel free to drop me a PM!
