[Moto G Q&A, Help & Troubleshooting] Matt Fillips:
I'm not sure if that is the correct place, It's my first post here, but anyway, here it goes:

It's not actually easy to root the motorola models of smartphone first because we theoretically have to unblock the bootloader first and then start with the procedure to root. My version is describled on the title, and I really want to do that, but how to don't lose nothing that allready is on my sd card an internal memory(I thing that this process wouldn't afect the sd but I'm not sure. I I'm wrong please correct me).

I'm locking for the saffer way! Ain't there a way to backup everything, unblock the bootloader and root. Then restore back until the positions of items and apps? Have exactally the same configuration but rooted? It could also there be any method to just root without unblocking the bootloader. Maybe?

What a just want is to have root permissions in my actual configuration, just like it is now. Maybe there could be an exploit to do so, without having to unblock the bootloader? This would be really helpfull!

Just one more thing. There are any procedure to create a virtual machine inside my phone, like the VM's in bigger machines. I know this sounds like fancing, but who knows where we can get?

In advance, thanks for anyone who read that and for those wich where patients enough to help.

Firstly, your XT1068 is a Moto G 2014 and I guess your question belongs to another forum (Moto G 2014 has a dedicated subforum - search). But to solve your problems using my current experience...

No, unlocking BL isn't hard, but yes, it will wipe stuff and you have to accept that. That's why the unlocking procedure should be done when you first got the phone... Once the unlocking is done, rooting is just as easy as on a Nexus device - flash a custom recovery and flash Superuser/SuperSU in it.

There once were some exploits for rooting under locked BL, but it looks like they all fizzled out after Moto pushed Android 4.4.3+. Plus, without a working recovery, you can't really "back up everything".

Lastly, there's something called Bochs that allows you to run X86 stuff (e.g. Win95 or even WinXP) on Android, which sorta looks like a virtual machine to me.

I'm having that problem now. I followed your instructions and got to the recovery mode or "Odin Mode" and it's been saying it's downloading for about 10 min or so. Any idea on how long it should take ?
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
Actually I believe it's the download mode that I'm in. It doesn't seem to get to the recovery mode when I press the Volume up key and power button for some reason.. Am I doing something wrong
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Follow these instructions implicitly.

Hold POWER + VOL DOWN + HOME.

As soon as it restarts change to VOL UP while still holding the other buttons.

Do NOT let go of any of the buttons until recovery boots.
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
That's what I've been doing exactly but for some reason it just goes right back to the logo screen. I was able to get into the recovery mode one time out of 100 and I went through the process of factory reset but it didn't solve the problem. Now I can't get back into it. It's weird because I have no problem getting into the download mode pressing the volume down but volume up doesn't seem to work. Not sure why or what to do
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
I'd try reflashing stock recovery then try booting into it again.

If it flashes then you should be able to boot into it.

Install Samsung usb drivers, put your tab into download mode, connect to pc, run Odin, load the file into the AP slot then click start.

i think i bricked mine...

These are the 2 screens i get whenever i try anything
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
You haven't bricked anything, there could be any number of reasons why it won't boot past the logo.

Easiest way to resolve it would be to reinstall the stock rom.

The second image is download mode.
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
That's the exact same situation I'm in. Every time I restart it I can't get passed that damn Samsung logo screen. I tried the whole flash with Odin process but I realized that when I connect the tablet to the computer, I get an "MTP Device Driver Failed" message so I'm assuming since the computer doesn't recognize it, even tried with KEIS and it doesn't, that I'm unable to complete the Odin job because that goes until 'Initialization' and stops there. Were you able to fix yours?
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Are you saying you still can't get into recovery mode?

Also what is your device model?
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
No I can't. I've tried a thousand times in all different sequences of holding the three buttons and it just doesn't go. It's SM-T800. They screen shots on the first page is exactly what I get. Either the logo screen when trying to get into recovery or download mode which it has no problem going into.
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
The two files below should boot you directly into recovery as soon as you start the tablet if you can flash them. Flash with Odin from the AP slot.

Make sure you put the device into DOWNLOAD mode first then connect your usb cable!

You can then do a factory reset and then try and flash the stock rom.

Stock recovery

Twrp recovery

.
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
Yeah I tried that too but when I connect the tablet to my comp, I get this 'Samsung Mobile MTP Device Failed' message so my comp doesn't even recognize the tablet. I even tried connecting with KEIS but that doesn't see it either because of that error. Idk if that's related to this issue that I'm having but I'm assuming that since the comp doesn't recognize the tablet because of that error, it won't finish the ODIN job. I get up to 'Initialization' and nothing after. I tried uninstalling and reinstalling the Samsung drivers and that didn't work either. Seems I can't catch a break here
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Mtp, kies and anything else is irrelevant, they are OS dependent.

Just put the tablet into download mode. Download mode works in boot loader mode. No need for the os.
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
Ok than Idk why it doesn't go passed the 'Initialization'. I tried multiple times and keep getting stuck on that
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Ok we need to take this step by step as theres something amiss here.

DID YOU AT ANY POINT WHILE THE TABLET WAS WORKING ENABLE 'REACTIVATION LOCK'?

1. Ensure the Samsung drivers are installed (important) Samsung usb driver

2. Before connecting anything to the PC put the tablet in DOWNLOAD mode first.

3. Plug the USB cable into a USB 2 port

4. Wait for the 'ADDED' message (if you dont get this it wont work)

5. Load the tar file into the AP slot.

6. Click START

7. If it doesn't start to flash reboot the tablet directly back into DOWNLOAD mode without touching anything else then unplug and replug the USB cable back in.

8. If it still doesn't flash try ODIN 3.07 ODIN

9. Report back and post a screenshot (if it doesn't work).
[Galaxy Tab S Q&A, Help & Troubleshooting] casual167:
I know for a fact that I never enabled the Reactivation Lock.. But you know, after literally days and hours including my entire weekend just searching the internet and trying every possible fix scenario that people have tried, I just gave in and sent it to Samsung this afternoon to have them fix it. Nothing I was doing seemed to work and I do believe I tried everything within my little knowledge to try. Let me ask you though, when I get it back in normal working order, would going through the steps to install the TWRP recovery and a ROM prevent me from being in this situation again or at least be able to actually fix it on my own?
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
If you dont mind tripping Knox and possibly warranty then I believe installing custom recovery is one of the best tools you can Install to a device.

It can get you back to a working state in minutes if you make a full backup.

It's a no brainer to install custom recovery if you intend to root and modify the device in any way.

Success

I have a SM-T700. The other day, I screwed up and wiped my tablet clean by accident. As a result, I couldn't get past the Samsung logo screen. I couldn't turn off the power. I couldn't boot to recovery.....Nothing. The only thing I could do was access Download Mode. While my first attempt was unsuccessful, I re-read this thread, followed the instructions and was able to flash my stock rom & boot to Recovery Mode by doing the following:

1. Downloaded and installed samsung drivers on my laptop.

2. Downloaded cf-autoroot-twrp-t700.tar on my laptop.

3. Downloaded and opened ODIN3 v3.10.6 on my laptop.

4. Went into Download Mode on my tablet. (Power+Volume Down+Home buttons)

5. Connected tablet to laptop via USB cord. (On my laptop, Odin displayed the word "Added")

6. Loaded cf-autoroot-twrp-t700.tar into the AP field and selected Start. (Odin did it's think, as evidenced by the red android icon, and then reboot back to the Samsung logo screen.)

7. Unplugged USB cord.

8. Held down Power+Volume Up+Volume Down+Home (all 4 buttons), which immediately took me into Recovery Mode.

Once in TWRP, I flashed the following:

1. CM12 - cm-12.1-20150519-NIGHTLY-klimtwifi

2. GAPPS - gapps-5.1-arm-2015-05-03-16-32-37

Worked beautifully. Thanks for the help.
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Hard reset is POWER + VOL DOWN.

Recovery mode is POWER + VOL UP + HOME.

Hold each combination of buttons, from an off state or immediately after restarting, until the desired mode is achieved.

There are NO other combinations of buttons to access the modes above.

Anything else that works is pure consequence of pressing those buttons with whatever other button you have pressed.

Recovery is pretty hard to crash. Any one that states they cannot get into recovery mode is probably not using the combination of buttons at the right time or not holding for long enough.

This is coming from someone who has SOFT bricked this device countless times in every way.

Recovery mode will always work regardless of the state of boot, os, cache or data partition.

You can wipe all of them clean and still access recovery.

I know this is an old thread but hopefully someone can help me. I was not able to get into recovery mode, so downloaded the files suggested upthread.

You need to flash the boot.img. Install the stock rom with odin or install one of the BOE6 kernels below:

Samsung Galaxy Tab 4 8.0 lollipop 5.0.2 stuck in boot loop

I have a SM-T350 stuck as well. I cannot find a reputable answer to the question of not being able to use the external storage due to being denied access to it. Also, many have similar problems and I've even contacted Samsung about this and they are more suspicious of tampering rather than fixing the problem. This all started during an update and the thing rebooted itself afterwards and it went directly into Odin mode. Nevertheless, the up button was pushed thinking that was the right thing to do and now it sits on my dresser. Its simptoms include not powering off unless powered down through recovery mode and all access is denied through external means.

How to rebbot without wiping memory

I got stuck at the Samsung logo and followed your instructions above. When in recovery mode, I clicked "reboot system now". That didn't do it because I still get stuck on the Samsung logo when the tablet restarts. I would be extremely thankful if you could help me to get past it without having to wipe data/factory reset!

Update: I deleted cache and then clicked reboot, which then led to the question whether I wanted to download OS, which I accepted. It has now been saying "Downloading... Do not turn off target!!" for the last half hour and if I try going back to recovery mode I just come back to the question whether I want to download OS.

Download mode means you need to connect your tablet to the PC and flash the stock firmware with odin.
[Galaxy Tab S Q&A, Help & Troubleshooting] mycal62:
if all else fails, remember on the samsung devices disconnect the battery for a few minutes and you can get back into recovery and restore or reflash.

look on youtube as to hoe to open the case for your specific device and disconnect battery ( look for replace battery for x device ) x being your device. this has bailed me out more than once.
[Galaxy Tab S Q&A, Help & Troubleshooting] Lightn1ng:
This should really never be needed because at ANY stage in a Samsung device, Power+Vol Down will do a full hardware reset...

Also might want to correct your spelling of "how" above... :p
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Totally unnecessary to go pulling the tablet apart.

All that is required is the right button combo.

POWER +VOL DOWN is reset,

POWER + VOL DOWN + HOME is download mode.

POWER + VOL UP + HOME is recovery.

I have a Galaxy TAB A 9.7 (SM-T550) which I tried to root as described throughout this thread and I too am stuck on the SAMSUNG LOGO.

I can put the device in download mode: It displays at the top of the screen: ODIN MODE PRODUCT NAME: SM-T550 CURRENT BINARY: Custom SYSTEM STATUS: Official WARRANTY VOID: 0x1 (4) DUALCOM SECUREBOOT: ENABLE (CSB) AP SWREV : S1, T1, H1, R1, A1, P1 SECURE DOWNLOAD: ENABLE

I connect it to a PC running Odin3 v.3.10.6 but I don't see the word ADDED appear in Odin. However I can load a tar file into the AP slot and when I hit START you can see the file transfer taking place on the Galaxy Tab which the reboots itself. ODIN displays

Hi Guys! I had the same problem. My Samsung Galaxy Tab S 10.5 SM-T805 was stuck at startup SAMSUNG logo after marshmallow update. I tried to hard reset, wipe data and cache, flashed the rom with previously mentioned stock recovery file method using odin, but it still didn't work. Finally, i was just playing around with KIES, which by the way was not recongnizing the device at its current situation (Stuck at samsung logo). I tried the Firmeware installation and Initialization option in Tools, KIES asked for model no and then the serial no of the device, after in putting this info, the process started and before it finished, my device turned on itself, and app optimization window was on the screen, after few minutes, going through initial setup, loging in with my account, it restored all the apps, Unfortunately, all the data was lost while i played around, But i am thankful, it working now..

I did have the same dilemma when i tried to downgrade from marshmallow to lollipop. Btw, i updated marshmallow with Smart Switch. For some reason Kies3 won't "read" my tab anymore and recommending smart switch instead. Decided to downgrade, so I did flash a lollipop thru odin and then it won't pass the logo anymore. My last resort was i flash marshmallow thru odin, then it booted normally. I don't know...Smart Switch may have 'done something' to my tab that I can't downgrade anymore.

I did try to downgrade again. stocked on logo. and then do your workaround, and it worked. thanks

Make sure your bootloader is up to date and it's quite likely you'll need to wipe data.

After that it will take around 10 mins to boot.
