fastboot permission denied, I'm baffled that this error pops up, and idk which vbmeta to flash, im thinking I'll do a full wipe and revert back to stock and root again

I've used it without issue. You did select recovery after you flash it right?

Yes, I did. I tried "adb reboot recovery". I tried select recovery in bootloader. It just boot, reboot and then boot normal. No error but no recovery...:crying:
This is embarrassing.....I powered off, walk out of the room. When I come back and try again, it works ......
I was trying for about an hour but never think of "power off"........
Thanks,

No problem. It's a little weird the first time I flashed it 3 times and then finally it went. Maybe it's something with the fact once we update our recovery our phone becomes bootloader unlocked.

Our phone is always bootloader unlocked... You meant "***Tampered***" ?

Yep. It says unlocked and then when you flash it goes to tampered. Maybe that's why it's a little sticky about going into recovery after.

I think EMMa should work also with unlocked bootloaders.
http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
Nope man, I think you need to install Flashtool on your pc, then install adb drivers from drivers folder in Flashtoll installation folder. Next download any firmware which you want to flash and move it to C:/Flashtool/firmware/here. Then just connect phone in flash mode and select that light in the left corner and select that firmware and tap flash. Done, your phone should boot now. :angel:

[SOLVED]Unsuccesfull root

Hi,
I tried to root my HTC One mini 2, but at some point got stuck. So now My device is not rooted, but not stock either, I try to install an update to the OS and it just reboots and then tells my an update is available.
When I enter fastboot it shows **RELOCKED** and S-ON.
I tried to re-unlok bootloader (adb and all in one toolkit) but when i choose "Yes" for unlock bootloader, "Entering recovery..." message shows and nothing happens. I still can choose between "Yes" or "No" option.
Please help, I can't stand this anymore.
Thx guys.

Got it, all I had to do was to keep power button pressed for about 10 seconds when asked to choose YES or NO for the Bootloader unlock, obviously after choosing YES option.
After bootloader was unlocked it was OK to flash stock recovery.
Everything back to normal now.
THX.

Bootloop after root

SM-T815
I have try to root with odin and cf autoroot and all work fine, then I have installed twrp for 815 5.0.2 version. After the installation the tablet restart on recovery mode, I try to make a backup and twrp works good but at the restart the tablet is in bootloop.
I can’t shut down. I can only access download mode and not recovery mode.
I have flashed the original firmware with odin and odin says PASS but at the restart it is bootloop again. I try to flash twrp again and odin says PASS, after this I can read on the start screen (the only one I can see) “recovery is not nandroid enforced”. I tried different firmware but nothing work.
Someone can help me?
Grazie 1000
Boot into recovery POWER +HOME +VOL DOWN then as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons.
Wipe data. If that doesn't work then factory reset.
Thanks for the answer. I try more than 100 time but it don't go in recovery mode. I tried to complete discharging and then recharging with the buttons pushed. Nothing. Every time it's stuck in the start screen and i can't shut down.

Not possible.
Try booting to Download mode then hit CANCEL then immediately hold HOME + VOL DOWN + POWER make sure you hold the buttons in that order and you must be quick.

Hi All!
I would like to share with you how I fix the preblem after root of my T815.
After long night and reading whole net I found the solution.
As you I also wants to root my device because of availible only one user. I wanted to have multiusers. So folowing the instructions downloading all software and after root I got bootloop. Trying everithing but no success. I wasn't able to flash even some of the stock ROMs.
Solution:
I found in Sammobile what is my current ROM and downloaded it. Then flash - no any problems. Went smooth. Then I root the device... and now I have rooted device with multiuser support.
It seems that after fresh flash everithing is OK. It seems that after you playing with your device for a while you enabled some options thats make your device to loop after root.
I wish you Happy New Year!
Nikog
Whoops sorry, I completely forgot to come back to you about this!
Glad you got it sorted.

Can't access ODIN mode

Hello guys. I just got a note 9 recently from abroad, and wanting to change its CSC via rooting, I tried to access ODIN mode. However when I press the bixby, volume down and power, it doesn't go there. Im pretty sure that those buttons are working. I wanted to flash custom recovery, but how do I do that when the bootloader isnt loading in the first place? Any ways on how to restore everything back to stock first so I can go back to ODIN? Please help.
Can you get into recovery? by swapping the volume buttons.. It has a reboot into bootloader option

Just tried what you advised. Nope, the phone goes into a normal reboot instead. Perhaps the bootloader is corrupted? Cause the knox is 0x0 and samsung pass is still working.

Enable dev settings and turn on debugging..
Use the adb command adb reboot recovery or adb reboot bootloader

Yes it does recognize my phone, but again it just does a normal reboot. The same thing when I try to reboot to bootloader using stock recovery.

I might be wrong, but as far as i understand
accessing Download mode on Note 9 is slightly different than the previous Notes models ?
(The button combo is slightly different?)

No, it is not corrupted.. Try to hold down the volume down + bixby and then plug in the USB-cable. It should boot right into download mode.
