Hi,
I want to install a custom ROM on my Galaxy Tab S. Therefore, I need to install TWRP as recovery. For that, I need to unlock my bootloader. I'm following this guide to unlock my bootloader: http://rootmygalaxy.net/unlock-bootloader-android-using-fastboot-commands/
I installed the appropriate drivers and ADB&Fastboot on my computer. Then, I enabled debugging on my Galaxy Tab S. Then, I opened the command console and typed: "adb reboot bootloader". My tablet then restart, but doesn't go into fastboot mode. Instead, it simply reboot normally.
I've tried this on both, Mac OS and Windows. It does the same thing on both systems.
I've tried to boot while manually pressing Home, Power and Volume down buttons. Then, my Tab S into a special mode: Odin mode. I know I've used Odin previously to upgrade my Tab S from Lollipop to Marshmallow. I don't know if the fact that I hve Odin doesn't allow my tablet to boot into fastboot. However, I would need to boot into fastboot to unlock my bootloader and, later on, to install TWRP in order to installer the AOSP 7.0 Nougat custom ROM to my Galaxy Tab S.
How can I do to boot into fastboot mode?
Thank you very much,
Blaccko

No Fastboot, use Odin.
Hi,
Thanks for your answer! You are right, I needed to use Odin instead! ; )
In fact, I was able to install TWRP via Odin. Then, with TWRP, I installed the custom ROM AOSP 7.0 Nougat on my Tab S. Thanks! However, I realized that the UI of my Tab S (on 7.0) is different than the one of my S7 (also on 7.0). I was told this is because Samsung personalize the UI of 7.0. As I didn't get 7.0 on my tablet from Samsung, is there a way to manually install Samsung's UI for 7.0 on my tablet?
Thanks again!

I've got installed quick reboot as well as xperia reboot but none of them is working.
I tried yesterday at home via fastboot tool with the commands mentioned in the root for all arc's thread and the relevant files to get into the recovery mode, but no chance.

you need to unlock the bootloader before you can use recovery via your pc. see how to:- http://forum.xda-developers.com/showthread.php?t=1034087
This will install the necessary drivers also, that will allow you to use fastboot, you will need to install unsigned drivers. Download the img from your link. Then you can reboot into fastboot via holding the required button or using doom's app, make sure you have the usb lead in. Then with the img in same folder issue the command fastboot boot recoveryARC.img via command prompt window. Both links explain it.
my bootloader is unlocked, otherwise it would not be possible to write it at least onto the phone.
I allready did everything at home where I'm possible to install uncertified drivers.
I already flashed via fastboot the updrade to 2.3.3 as well as yesterday the rooted 2.3.3
Also tried doom's app, nothing changes.
just for confirmation here are the steps i did on the arc since the beginning:
Unlock bootloader, beginning of May (since when it's available)
rooted 2.3.2
upgraded to 2.3.3 via fastboot (root lost)
now the steps from yesterday:
Phone off
CMD: fastboot boot recovery.img
connected phone with USB cable and pressed menu button
Blue led on
at the CMD window recovery.img was shown as transfered to device
Arc was rebooting, but not into the recovery mode.
basically i'll try today with a different recovery img maybe thats the reason.

I explain again!
MY RECOVERY IMAGE (your link above post #169) is a recovery boot only, NOT FLASH! just fastboot boot.
The FreeXperia kernel incl. recovery is only for flashing, NOT BOOT!
So you have 2 easy options, but i provided the boot only version to help stock users to have a recovery!
Not other recovery image that MY POSTED can be used to fastboot boot into recovery.
Regards
So, finally i got it working:
In my case its only possible to get into the recovery mode via following setup:
Connect arc with fastboot mode (unlocked bootloader necessary).
recovery.img from this post: http://forum.xda-developers.com/showpost.php?p=14903452&postcount=169
then
cmd: fastboot boot recoveryARC.img
then i get into the
thats it.
The app from doom is not working in my case. tried it now twice (once USB cable connected, once not), not working in any case.
If you get the first sony ericsson screen it was not working. it needs a while on a black screen (longer than waiting normally for sony ericsson) but then you're directly in.
Exactly the reason my lg is with me for the last days, just flash roms with 'rom manager' and playing with it and test things... Arc is to complicated for me to get this to work...

It's not like someone has step-by-step instructions in, say, a guide...
I know, like I said, very complicated, especially when you only have an imac as computer at home and your laptop is broken:-D, so not able to open .exe files at the moment....
for lg I only needed to root and install "ROM manager", even people like me can use that. Plenty of roms and there you go.
For now I themed with uot kitchen, but this is the first time in two days I picked up my arc again just because the lg with custom rom is lightning, blazing fast and smooth...

ROM Installation Instructions
Want to try to flash a Remix OS ROM to other android devices? Yes! We will soon put the Remix OS ROM on the Internet for users to download and flash onto their own device. To start, we will provide the guideline and support to flash the Remix OS ROM on Google Nexus 10.
Disclaimer
Flashing Remix OS ROM on Nexus 10 requires strong android knowledge. Flashing this ROM on Nexus 10 will be at your own risk. You will have to bear responsibility for all the resulting consequences. Jide will NOT be responsible for any damage caused.
Further Note:
Unfortunately, as a startup, we lack the resources to support installation Remix OS ROM on other android devices, thus, we will ONLY provide support for the Nexus 10 device. The Nexus 10 is a touchscreen tablet manufactured by Samsung with direct support from Google. It is the second Nexus tablet. Of course, we will look forward to the support of Remix fans to share with the world about their experience on flashing the ROM on other Android devices.
Installation Instructions
The followings are the steps to install Remix OS ROM: Unlocking the device & Installing image files using fastboot
Unlocking the device
1. Make sure your computer has working fastboot and adb.
2. Enable USB debugging on the device.
3. Connect the device to the computer through USB.
4. From a terminal on a computer, type the following to boot the device into fastboot mode:
- adb reboot bootloader
5. Once the device is in fastboot mode, verify your PC sees the device by typing
- fastboot devices
- If you don't see your device serial number, and instead see "", fastboot is not configured properly on your machine. See fastboot documentation for more info.
- If you see "no permissions fastboot", try running fastboot as root.
6. From the same terminal, type the following command to unlock the bootloader:
fastboot oem unlock
7. A disclaimer will display on the device that must be accepted. Use the volume keys to cycle through the options. Pressing the power button should confirm your selection.
8. If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
9. Since the device resets completely, you will need to re-enable USB debugging on the device to continue.
Installing image files using fastboot
1. Make sure your computer has working fastboot and adb.
2. Download images
- you should have a download link from us in the email. The information of the image zip file:
- Images Zip File Name: images_Nexus_10-5.0.2-B2015070105-signed.zip
- md5: bdb08b6a0508dd1088f177a9e19c2875
- sha1: 9d6df824ef8c32af1a3a9d89e5f870133bcdebf6
3. Unzip the downloaded zip file ( images_Nexus_10-5.0.2-B2015070105-signed.zip ) and go to the folder
4. Connect the Nexus 10 to the computer via USB.
5. Make sure the fastboot binary is in your PATH or that you place the recovery image in the same directory as fastboot.
6. Open a terminal on your PC and reboot the device into fastboot mode by typing
adb reboot bootloader
or by using the hardware key combination for your device while it is powered off.
7. Once the device is in fastboot mode, verify your PC sees the device by typing
fastboot devices
- If you don't see your device serial number, and instead see "", fastboot is not configured properly on your machine. See fastboot documentation for more info.
- If you see "no permissions fastboot", make sure your UDEV rules are setup correctly.
8. Clean the existing data by entering the following command:
- fastboot -w
9. Flash images onto your device by entering the following three commands:
- fastboot flash system system.img
- fastboot flash recovery recovery.img
- fastboot flash boot boot.img
10. Once the flash completes successfully, run the following command to reboot the device into recovery to verify the installation.
- fastboot reboot
Some of the external link of this documents will link to CM website. The installation process is referenced by http://wiki.cyanogenmod.org/w/Install_CM_for_manta
You are the man!
Yea that didn't work for me, no recovery on boot to recovery just blank screen. Also stuck on remix boot logo.
Works for me. You have to fastboot -w to wipe your device, then flash at least the system and boot image through fastboot.
I didn't wipe my device ,didn't wanna lose the sdcard content. I simply did a factory reset from twrp. Question, can it be rooted with cfautoroot like normal android 5.0?
its totally a new dev rom! the best out there! Love this rom!
How to add other languages, for example, russian?
So far I'm loving this rom. The only thing is that I wish there was a way to add widgets.
For some reason i can't hear any media volume whether it be youtube videos, music, or netflix. Any ideas on what might be wrong?
For some odd reason Tapatalk doesn't work on this ROM for me.
How do we root? Anyone know?
I've found this YOUTUBE link, but didn't test yet

ADB - do you have USB debugging on? is Fastboot not working either? may need to re-install drivers on your PC
TWRP - are you saying it was installed, but you can't access it? unclear on your exact issue.

Okay, I'll power off the tablet, then hold volume up AND down + power and that boots it into.... Recovery I think. When it boots to that, adb and fastboot are connected. I have a Nexus toolkit installed on my pc for flashing etc. Whenever I click flash recovery to reinstall twrp, it reboots the tablet into the OS and that's it. And when it's booted into the OS, there's no adb connection. And USB debugging is on. I finally just gave up.

Power + Vol Up/Down boots to bootloader.
If you have fastboot, then download the TWRP img file to your computer and issue the following command in the bootloader (forget the toolkit)
Code:
fastboot flash recovery <recovery img file name>
then you should be able to get into TWRP by using the Power Up/Down buttons until you see "Recovery" aligned with the Power Button.
press Power and you should be good to go.

I'm in the EXACT same situation. Fastboot and adb not working for this, but all my other android devices are working fine. Luckily I have twrp installed so I'll just flash something else then start over on a diff rom.
Edit: and of course, just like that, I restart one more time and it actually works. very temperamental i guess.
This is a great ROM with fast clean I interface. I used official manta 5.1 from Jide. Unfortunately google device manager now sees my N10 as a Linux device, and google play services will not load properly so I cannot play cloud connected games which is really sad, I will have to back to an android custom ROM..... If you don't need play services give jide a try.. Its a pretty cool concept.
HI everyone,
I updated "successfully" from Kitkat to 5.0.2 on my rooted (stock ROM) Nexus 7 second gen.
Unfortunately, when I tried to upgrade to 5.1 everything seem to be normal until the device rebooted and it went through the "update process". 3/4 the way through, the green droid went on his back and the "ERROR" message appeared.
I wiped the cache partition but that doesn't help. I tried to download the update in safe mode, but no success. I also find it odd that each time I reboot my device, I get a message from Android that it is "updating my apps".
If I didn't have any apps and a lot of data on my Nexus, I would wipe the device clean but I'd rather avoid this, if at all possible.
Is there a way to upgrade to 5.1 or reinstall 5.0.2 without losing everything?
Thanks

No problem. As you rooted it before then presumably it is unlocked and equipped with custom recovery, so all you have to do is:
boot TWRP
connect PC
transfer data and APKs to PC
flash OS
If you don't have TWRP installed, then boot it like this fastboot boot twrp-3.0.2-0-flo.img

Hi,
Thanks for the reply. I rooted with Kingroot. I don't believe I have a custom recovery. The bootloader is locked as shown when I boot into recovery mode.
I want to avoid transferring my data and APK files to my PC.
Should I assume there is no way of reinstalling the OS without wiping out the device?Also, there is no link in the above quote: fastboot boot twrp-3.0.2-0-flo.img
Since I got no other replies, I went and restored to factory image. I do have another question. I hope I get a better response there: http://forum.xda-developers.com/nex...a/nexus-7-2013-wifi-root-marshmallow-t3515072
Thanks for the reply.
Can we compare using fastboot flashing TWRP vs Nexus Root Tool Kit: http://www.wugfresh.com/nrt/? I ended up using this utility instead because it was pretty much one click and it didn't require command lines and for whatever reason, I found instructions using fastboot a bit confusing. Which method is better or has more advantages? I left my bootloader unlocked.
Incidentally, I think there was something wrong with my Nexus image. As a result, I did use Google's instructions on how to flash etc. the OEM image. Instructions weren't ideal but I managed to figure things out: https://developers.google.com/android/images
The instructions are here which I assume would be similar if I wanted to fastboot TWRP?
To flash a system image:
Download the appropriate system image for your device below, then unzip it to a safe directory.
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
Using the adb tool: With the device powered on, execute:
adb reboot bootloader
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 ("hammerhead") into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.
If necessary, unlock the device's bootloader by running:
fastboot flashing unlock
or, for older devices, run:
fastboot oem unlock
The target device will show you a confirmation screen. (This erases all data on the target device.)
Open a terminal and navigate to the unzipped system image directory.
Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.
Once the script finishes, your device reboots. You should now lock the bootloader for security:
Start the device in fastboot mode again, as described above.
Execute:
fastboot flashing lock
or, for older devices, run:
fastboot oem lock
Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.

Also, I could've sworn that when I rooted KitKat on my Nexus, my data wasn't wiped out. I don't recall doing anything to the bootloader. I can't recall which method I used, but I know for certain I didn't use the Nexus Root Toolkit. I should've recorded my steps when I rooted.
i rooted my nexus 7 using towel root on kitkat .. i unrooted using supersu... and ota untill marhsmallow with out a problem never use kingroot as its so un stable.
For those that, like me, could not get driver recognition on the latest Win 10 x64 no matter what you tried. And ,yes, using every tutorial I could find on this and two "other Forums". Odin failed to see my device (still can't) Cydia impactor allows rebooting into fastboot and D/L but doesn't connect in either alt. mode. Yes, drivers all removed and replaced in varying states (usbdeview, etc.).
But ADB/Fastboot works!
Make sure you have your adb/fastboot drivers installed universally (Check this Fabulous Forum)
Download device-specific TWRP - I used this one for the 4gb version - https://www.dropbox.com/s/b7u3k1mgpppxlyx/recovery.img?dl=0
L.Shift-R. click in the folder you downloaded to (Open Command Window Here) - "adb devices" (to make sure device registers) then - "adb reboot bootloader" gets you into fastboot. - "fastoot boot {your-recovery-name}.img"
I got a fully functional TOUCH CAPABLE TWRP. Which I proceeded to load this - https://www.dropbox.com/s/j1owqv7mjkdpo75/UPDATE-SuperSU-v2.46.zip?dl=0 - and, VOILA! ROOT!!
I had similar issues with my laptop and drivers. Used a friend laptop in the end to "see" the phone and install twrp.

When I try to boot the recovery.img with fastboot it says that my OEM is locked. I check OEM unlock in developer options, then I do: adb reboot bootloader, then fastboot oem unlock. A warning appears saying to press VOLUME UP button to continue, voiding the warranty or VOLUME DOWN to go back. I try to press VOLUME UP and nothing happens... how did you do it?

Hi there, I have the same issue. No success
I found a way, instead of volume up, use the home button this worked for me.. however after I unlocked the OEM and flashed TWRP the phone didn't want to boot anymore. It was stuck on Elephone logo with warning: "Orange State: The phone has been unlocked and can't be trusted. Your device will boot in 5s", however it didn't boot and stayed like that for almost an hour. Had to flash back the stock firmware to boot. Tried 1 more time the procedure to root but again the same. Maybe I do something wrong?
stock fw flash back
Hi, please can you help me with how you flashed back the stock firmware?
I get an error message with twrp : invalid zip file format.
Thank you in advance!

I read somewhere the is a zip inside the update.zip & is that one that is flash able with twrp.
Have a look
During the main time I managed to flash the 0218 stock rom.
I still got the orange message but the phone finally boot. Then I just called the twrp recovery img via atb. I did nothing only touch the reboot in the twrp screen and since then "Orange status...." again.
May be the twrp recovery img is not the right one...
Bad command "fastoot boot {your-recovery-name}.img"
after OEM alow (informacion phone/compilacion number touch fast 9 times/access/alow oem)
fastboot oem unlock
"fastboot boot {your-recovery-name}.img" for me is fastboot boot recovery.img and all OK
bat still not working (phone not thrust unlocked bootloader cleaning data in 5..4..3..2..1.. and rebot)
I can get my Zenfone 2 up to the fastboot screen, but no further.
Under PC device manager is shows "Android-Phone" as the device, but no drivers loaded.
I've tried a few different drivers, but even though they seem to install OK, "Android-Phone" (in device manager) still won't show as having a driver.
Some threads say I have to enable Android Debugging, but how to do that when the ONLY screen I can get on the phone is fastboot??
Help???
Boowho??
You can try this.
1. Uninstall all drivers for phone you installed on PC, then reboot.
2. Disable antivirus on PC then install standard Intel android device usb drivers. You can download them from Asus website. Then reboot again.
3. Connect phone to PC in fastboot mode.
4. In the device manager you should see "Asus android device" under which "Asus android bootloader interface".
5. Check connectivity in minimal adb & fastboot software (you can get it from XDA) by command "fastboot devices" without quotes. It should answer "some number<space>fastboot".
If all is ok then you can flash raw stock firmware in fastboot mode & update it to latest version OR unlock bootloader, flash TWRP & install custom rom.
Thank you Sanesh. I got all the img/bin files successful now. However, the ZF2 has this issue when you select recovery from bootloader screen it gives dead android. You can then (extra step) hold power and VOl + and get into stock recovery. This is a flaw in the original firmware, I think.
BUT, this extra step is causing TWRP not to be entered. Stock recovery is OK, but not TWRP.
I had to recover the phone using the SOC drivers; before that TWRP worked perfectly.
Thanks
Have you unlocked bootloader ? Unlock bootloader first then flash twrp using giovix92 method. Then reboot to recovery.
Thanks. Turned out I was using a twrp image that is only for marshmallow. I still use lollipop. Every thing is now back to where it was before I had to recover the thing using the SOC method.
Lesson learned. un-root before trying to upgrade to MM.
