[Q] Nandroid? - Galaxy Tab S Q&A, Help & Troubleshooting

Ok, after a lot of misinformation, bad advice and just plain wrong instructions (people were telling me to hold down power + volume down but all that did was boot back to the loader, home + volume down + power was what worked) I finally managed to get my Galaxy Tab S 10. 5 rooted. Or so it seems. But when I went to try and uninstall some of the bloatware, all I could do was "disable" the crap.
So, time to flash a ROM, right?
From what I've read I should do a Nandroid backup first, but what does that mean and how do I do it?

To make nandroid backup you need to flash a custom recovery, either TWRP or CWM, using Odin (same way as you did to root).
Here is link for TWRP

Make sure you've installed Supersu.
Then use flashify to install TWRP 2.8.4.0.

Install a system app remover to uninstall system apps. Do the nandroid first.

Flashing Rom help!!!

Im fully rooted, and I was able to flash to Fresh's rom. I guess not deleting the Pc36*** file, when it rebooted, i panicked (lol) and reinstalled the stock rom...
Now I have absolutely no idea how to get back to the green recovery screen where I can flash from zip...
Is it me, is it a adb thing?
Any help is greatly appreciated....
if you have a custom recovery: power the phone off, hold volume down and then press the power button. Continue to hold volume down. Make sure the pc img is off the sd card, wait for it to go through the motions then enter recovery

Where do i go from here partner?
yeah, so try doing what I said above. Turn off phone, hold volume down, press power and release and continue holding down. You will get to hboot and it will scan for the pcimg and should not find it and present you with a menu. Go to recovery and that should be it

I did so, and its just sitting idle with the phone & red triangle. My only option from here is vol up and power to take me to the blue reboot screen...
Thanks for the help by the way...
hmmm, I would have thought you would have a custom recovery from Part II of toast's rooting guide. Have you unlocked your nand through that procedure?
in any case, you can always download rom manager from the market, and that will allow you to install a custom recovery and boot into recovery from android. I am not sure if the new version requires nand unlock so make sure you have done part II of toasts root guide

I was able to flash from the green recovery screen tho. Im not understanding this. I even updated the radio and wimax thru the same green screen...
Thanks for your help..
how were you flashing before? did you use clockwork recovery (i think thats what it's called) through rom manager?
I dont think that I have clockwork on my phone. I was able to vol dwn/power, hboot would see the PC36*** because I was not informed to delete it, and instead of updating i selected NO, and it took me to the green recovery screen...
Ok, so I would try flashing the recovery from the second part of Toast's rooting guide. If you can do that, then you can just use the volume + power thing to get to hboot, then select recovery and it should take you into the recovery that you flashed. From that recovery you can wipe flash backup, and all that good stuff.
you dont need to do the whole part 2 over, just the part about flashing the custom recovery.

Help Booting up loop / need to get in recovery help!

Ok i had a rooted phone,
and installed rom manager it was also flashed to cricket wirelss also.
anyways i decided to try and install the cm7
So i did and before that i made a back up via rom manager app
And so i updated and it installed
and now when i turn on phone
It stays at the cyanogen mod 7 with icon blue icon screen
and circle thing
How do i boot into recovery menu????
I had the latest recovery menu also,
I NEED HELp i just want to restore my backup from before.
First off you should power it off completely, then hold the power button and volume down at the same time. Next, you need to navigate the bootloader and go down(with volume down key) and select recovery with the power key. That should take you to recovery. I hope you made a nandroid before you flash another rom; if you did just restore your nandroid and you should be good to go.

[Q] Need a stock recovery :/

Hello; I have rooted my phone, but during the process, I forgot to save and backup my recovery partition. Now, my recovery contains TWRP instead of stock HTC recovery. The issue is that it prevents the stock ROM from aplying updates.
I would need either, a backup clone of a stock recovery (in dd, cat, of afstboot format), or, a method to apply the update from TWRP recovery ...
Thanks.

First tried 1.16.1700.16, all failed (with horrible error messages, and phone stuck for 25mn ... ); to cancel errors, I tried to leave the phone 10 plugged on USB, then 10mn unplugged; unplugging helps rebooting.
Then I tried stock_recovery_1.54.1540.9_recovery.img and this time it all went good. And update was successfully applied.

If your phone locks up, don't do all that plugging in unplugging etc..
unplug phone, hold vol up and power exactly 10 sec, let go of both, hold vol down and power to go to bootloader

[Q] [Q&A] Flashed TWRP but keep going to Stock Recovery?

I rooted a while back with Stump. I recently used flashify to flash twrp recovery as I want to install a lollipop ROM. It was successful and when I restarted the phone as prompted by the app, I went to the TWRP recovery screen.
1) When i manually power off the phone and try to boot into recovery I end up on the Stock recovery page rather than TWRP recovery. The only way i can get back to twrp is by reflashing it in the flashify app. Any idea what is going on?
2) While I was in twrp i explored and tried to create a backup. Any reason why twrp failed to recognize my external SD card and would not let me mount it? My computer and phone both access it without issue.
Thanks for the help.
If you want answers, you need to provide more info, not just ask for help and not give the required info.
What phone model.
What Rom are you running? Lollipop or KitKat and what version.
What steps are you doing to try and get into TWRP.
You don't need to reflash it every time with flashify, open flashify hit the menu button, the 3 dots in the top right and guess what, reboot options.
Can't help you with the backup in TWRP not saving to your SD Card, but you could backup to internal, then reboot and copy the backup to your pc then try and copy it to SD Card.
Sorry for not being more specific.
Verizon VS985
Still running rooted stock 4.4.2
I'm holding down power/volume down to try and manually enter twrp.
I'm worried about relying on the app in case something goes wrong while flashing and I need to get directly to recovery manually. I was going to do the backup to internal and copy method but that leaves me out of luck if I need to restore from the ext SD in the event of a bad flash that stops me from booting the phone.
If you are rooted, download Quick Boot from Google Play Store and and use it to boot into recovery, or as @samorgs said, just use the 3 dots button to access into the boot option. If you can boot it into recovery mode through that, it means you have TWRP installed already. So it is normal to go to stock recovery screen manually. Same as my phone, I off my phone, hold down power+volume down and wait till LG logo appear, release power button and hold it back (still holding volume down) and it will bring me to stock recovery page, proceed with YES to factory reset and this will not wipe your data BUT brings you to TWRP recovery.
Hit Thanks if I've helped

You can refer here
So, just to be clear, in order to get to TWRP manually you have to select factory reset from the stock recovery page (reached by using power+vol down while the phone is off). This will not wipe any data but will in fact bring you to the TWRP screen?
Is this always this case with our model? Can anyone confirm this?
Thanks!

Not exactly how you described it. You have to hold Volume down and the power button until the device's screen turns on, and then as soon as it does, you press them again. (volume down and power.) only holding volume down and power will take you into download mode.

Samsung Galaxy Tab S (10.5 Wifi) - "Semi-Rooted" Device Crashes on Reboot

Recently tried to root my Samsung Galaxy Tab S (I am not allowed to post links yet so I'll just say the site is techbeasts)
I believe I went through these instructions and followed them all precisely.
This method also installs SuperSU on my device..
However, I tried checking the root status with Root Checker, and it says "verification failed"
I then checked SuperSU, and it said something along the lines of "binary needs updating". I tried the "normal" method for doing this twice, but it didn't seem to work. There is an option presented in SuperSU to do this through TWRM or CWM, so I tried that option. ( NOTE I do NOT have TWRM or CWM installed)
**Then when I started the tablet, a whole bunch of messages came up saying "unfortunately, ____ stopped" [/B]and a whole bunch of these are there. I'm sure this is a crash.... **
I managed to get the tablet back to semi-working state by using the factory reset from the recovery partition (it's the stock recovery partition). However, the crash-on-reboot problem still persists.
Any help on getting back to working state? I can use the tablet but I cannot restart it as it will crash again (have had to do the factory reset from recovery twice now...)
I should mention that i am trying to:
1) have a rooted tablet
2) Not have these crash-on-reboot issues...

Best would be to flash your firmware again with Odin. You can download your firmware on sammobile (see link below).
You will need Odin for this, the correct drivers on your pc and to have USB Debugging on (under Developer options in Settings).
Unzip the firmware you downloaded and put it in PDA or AP in Odin, connect your tablet in download mode (power + home + volume down , afterwards volume up to 'continue') and click start.
Go to TWRP website, search for Tab S 10.5 and download the latest TWRP (tar-file).
Download supersu.zip as well (see link below, you can download 2.46 or 2.49 beta) and put it on the tablet or external sd card.
When this is done and your tablet rebooted (can take a while), reboot in download mode, open Odin again and add the twrp-tar you downloaded before (same PDA or AP).
Tablet should reboot as well after that. To enter recovery mode press home button + power button + volume up. This should bring you in TWRP recover. Flash the supersu.zip you downloaded before, reboot and you should have root.
http://www.sammobile.com/firmwares/database/SM-T800/
http://forum.xda-developers.com/showthread.php?t=1538053
Note: should the tablet reboot in stock recovery after you flashed the TWRP-recovery. Go to download mode again, fire up Odin but uncheck 'Auto Reboot' and flash TWRP-tar again. Once it's done, hold power + home + volume down, you will get to the screen again where it says volume up to continue volume down to cancel and reboot. Choose volume down but quickly press power + home + volume up until the screen turns on again. That should take you straight to TWRP recovery. You can flash supersu.zip and TWRP recovery should stick now.
Good luck!
Wow, how to massively over complicate something.
Just install the stock firmware, then look for my build of cf_autoroot in the dev section, flash in ODIN. Done.
If you want to upgrade twrp to the latest version you will find it in the dev section too. This version fixes some of the issues with the official version and has more options.
Hi guys,
TThanks so much for your replies! Complicated or not, anything helps...
I had previously used Odin to flash the rooted firmware to the tablet, so I amn faniline with the software.
Alta1r: looked at the links and it looks like sprue stock firmware. A couple of questions about this procedure:
1) Is it normal that the stock firmware file (as downloaded) is larger than firmware images used to root the tablet?
2) Would using TWRP to flash Supersu onto the tablet root the tablet, even if the stock firmware is installed?
Thanks again guys!!
Not sure what you mean with firmware images to root the tablet. Do you mean a custom rom? Those should be smaller in size yes, as the are usually de bloated.
Maybe you flashed a wrong version if a custom rom for your tablet before, that would give you problems when flashed.
Both my or ashyx's method can be applied on a stock rom. I'm running just stock with root.
@Asynx: I flashed the latest firmware on my T800 this week and twrp didn't stick after the first boot. Tried many versions, also the one you mention in the dev section, but to no avail. Even replaced the recovery in the samsung's tar file and flashed it like that: twrp screen showed up right after the flash, but on next boit it was stock again. Only way to make it stick was to reboot into recovery right after flashing it.
Never had that problem before though on the Tab S (did have it already once on Galaxy S6).
Edit: forgot to mention I hadn't seen there was cf-auto root available for our current firmware. If I knew it would have saved me some time. Could have flashed the recovery with Flashify afterwards.
Apologies I am still getting used to the lingo with this stuff
Have done some stuff with Linux and some tweaking in Windows as well, so figured this shouldn't be too bad...
@Alta1r: so the process you describe is what you said, flashing the stock ROM and then root it afterwards...
Will try this process and report results here
(aside: I think the tablet was working fine after flashing with CF autoroot ROM -- is that the right word? -- what I think ruined it was when I told Supersu to try updating its binary through TWRP or CWM....which isn't yet on my tablet)

It seems since lollipop this has to be done if flashing over stock recovery or it will be replaced at boot with stock.
Twrp will patch the recovery install script at first boot.
Sooooo...
First off, thanks for the "luck wishing"
I decided to try the method of @Alta1r.
@ashyx - I tried the CF-autoroot thing before (this was first attempt at getting a rooted tablet), and this didn't work for me. So I wanted something a bit more "hands on".
This is procedure I followed and worked for me (as of this post):
1) Before I began, I accidentally went into recovery mode instead of download mode. So I had to restart the tablet *gulp*
....yet I was able to restart just fine (no crashed as mentioned in my first post). I think this ~might~ have something to do with the fact that I downgraded the version of supersu that was "updated" through Google Play, but I'm not really sure...
2) Downloaded all relevant files.
3) Flashed firmware for tablet as instructed:
Alta1r said:
Unzip the firmware you downloaded and put it in PDA or AP in Odin, connect your tablet in download mode (power + home + volume down , afterwards volume up to 'continue') and click start.
Click to expand...
Click to collapse
Result was that tablet booted just fine!
Made sure that a few apps worked OK, and also rebooted the tablet a few times to make sure it was stable
(this is a linux based system, not Windows, but I still like reboot tests for stability checking...)
4) Next I did the TWRP flash through Odin:
Alta1r said:
Go to TWRP website, search for Tab S 10.5 and download the latest TWRP (tar-file).
When this is done and your tablet rebooted (can take a while), reboot in download mode, open Odin again and add the twrp-tar you downloaded before (same PDA or AP).
Click to expand...
Click to collapse
TWRP flashed fine. But then....
5) Tried to boot into TWRP recovery:
Alta1r said:
Tablet should reboot as well after that. To enter recovery mode press home button + power button + volume up. This should bring you in TWRP recover. Flash the supersu.zip you downloaded before, reboot and you should have root.
Note: should the tablet reboot in stock recovery after you flashed the TWRP-recovery. Go to download mode again, fire up Odin but uncheck 'Auto Reboot' and flash TWRP-tar again. Once it's done, hold power + home + volume down, you will get to the screen again where it says volume up to continue volume down to cancel and reboot. Choose volume down but quickly press power + home + volume up until the screen turns on again. That should take you straight to TWRP recovery. You can flash supersu.zip and TWRP recovery should stick now.

As predicted, Alta1r, the TWRP didn't flash properly. I got an error on the stock recovery saying:
"Error message is "E:ensure_path_unmounted failed to unmount /efs (Device or resource busy)"
So I tried your odin + reboot trick as above, and this booted into TWRP recovery.
6) Then I flashed supersu.zip (had kept on microSD card that is in tablet).
Andddddd.....

Glad to hear all went well, and by the looks of it had fun doing it.
Although computer/device problems can get me agitated, I still have fun in the end
Not sure if I can ask this here, but two other slight issues after the rooting:
1) Upon rebooting the tablet, I always get the message "android is upgrading", even if I didn't touch any apps through Titanium Backup or other root-only apps that are meant to remove pre-installed applications.
Is this an issue? And if so, is there a way to get rid of this?
2) I am able to uninstall/remove apps with Titanium Backup (freezing them isn't possible without the paid version of the app), but I am not able to restore them. I made a full backup before I started to uninstall stuff. I put on USB debugging mode in developer options, but still I cannot put apps back. Any thoughts on this?
Thanks again!

I wouldn't worry about the upgrading message, most get that.
AFAIK TB requires a kernel that can be set permissive to fully function.
If you want the ability to remove and restore apps use system app remover (root)

Yes I am sure I have full root.
I used root checker to check if I have full root access and it comes back green (to say root access is good).
(Just checked again now before posting this...)
Using either Titanium Backup and Root App Deleter, I am unable to restore deleted apps...
I have enabled USB debugging in the developer tools, as instructed to by Titanium Backup....
I read something about the "mount namespace separation" in supersu, I might try to toggle that option to see if it helps this situation.
Root app deleter? Is that system app remover?
Also what is the error when you try to restore with it?

That doesn't mean it doesnt restore. It says that every time iirc. Check in system apps to see if it restores.

Okay I'm just going to say exact issue...
I deleted calendar storage, thinking that it's part of Samsung's calendar app (when in fact it is used by all calendar apps).
So now Google Calendar doesn't show me my calendar....and I'm trying to restore calendar storage, but it's not restoring
(had previously deleted through System App Remover, but now can't get it back)
Edit: I uninstalled and reinstalled Google Calendar, and that seemed to bring back my calendar.....
Sorry to cause you this trouble, I guess I panicked too early...
But will still be careful of what I remove...
