Hi,
i rooted the galaxy tab 10.1v according your instructions.
There was no need to unlock the boatloader, because the screen showed following for me after entering fastboot.
Currently i am rooted, and everything works fine.
But when trying to flash latest CWM, I got stuck at the screen provided above for 15 minutes right now. how long does this take normally? booting with fastboot into cwm is taken only seconds
Booting into CWM in fastboot works fine - flashing not.
What could be my problem?
Could you also post a picture of the OPEN lock symbol during booting? i cannot imagine, if my lock is closed or not, the symbol is not really friednly designed.
When you flash a recovery it doesnt boot into recovery. To go into recovery you should run 'adb reboot recovery' .
You can exit fastboot by holding the power-button until the screen goes dark.
ps. Your recovery is flashed correctly even though on the tablet screen it may appear like it is still busy.
ps2. Next time please respond in the corresponding thread instead of opening a new thread.

***FIXED***
Update:
I was able to resolve this, here is what I've done in case others happen to have the same issue:
Turn on computer volume, reason being I had mine off and even though it appeared to skip over fastboot with the OTG method, it in fact was enabling for a sec or 2 then moving on as I could hear the USB connection chime.
NOTE: I had to press and hold to the LEFT of the Nvidia symbol until I heard the USB pick up chime, once I heard the chime I released my finger.
Prior to plugging in the power cord, I ran "fastboot boot <yourfilename.img>" and it sits at waiting for device...
Device took it and booted me into TWRP, I then flashed the Unofficial TWRP for the SATV, by choosing Image, then finding the .img that I already had on the internal storage
Rooted with SU, rebooted system and everything is now good to go.
Root, custom recovery and also Fastboot stock menu is back.
---------------------------------------------------------------------------------------------FIXED------------------------------------------------------------------------------------------------------------------
Hello All,
Long time lurker, now reaching out.
Just looking for a little help with my SATV Pro 500gb.
Here is the background:
Out of the box today, booted up and enabled ADB and jumped into fastboot for the bootloader unlock
Process took about 2 hours as the info said it would. Device rebooted, perfect working order.
Decided to flash TWRP for SU install along with possible custom roms, etc.
used this tool:
http://forum.xda-developers.com/shi...l-windroid-universal-android-toolkit-t3291266
Device said "please wait...." in fastboot screen, appeared finished and device rebooted into the the OS.
Here is the problem:
I go into command and adb reboot-bootloader, device reboots, I see the Nvidia logo and it boots into the OS, skips right over Fastboot
Shut it down, attempt the OTG, power cord ~3 secs over and over, hangs at logo and then boots in to the OS.
I reset the device, hoping the recovery OS would reflash the fastboot image, appears not to be the case.
Currently I am stuck with no fastboot access, device boots to OS no problems, but as far as fastboot is concerned I cannot access. Appears something went wrong with using that 1 click tool for flashing recovery.
Now before anyone chimes in, adb reboot-bootloader will not boot into fastboot and I've attempted the HW method listed on Nvidias dev site. Its 100% nogo.
Current State of device:
No fastboot
OS boots no problems
ADB works
No Root
Thanks for everyones look and help!
Okay, to start with, I've read the other threads about this. I understand the process that *should* work:
1. Power off.
2. Then, press and hold both all Volume Down + Power buttons at the same time until the LG Logo is being displayed on your LG V20.
3. Now, release the keys and press the above combination again however, this time you should wait until recovery mode menu is displayed.
...and I've tried the version where you keep holding the Volume Down button the entire time.
So, yes, I've reached the white screen where it asks you if you want to do a factory reset. I've hit "Yes" to both questions. The problem is that it really does a factory reset then.
---
After unlocking the bootloader, I installed TWRP via fastboot:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
...everything went fine.
But I can't get into recovery. And since I'm waiting to have TWRP working so that I can flash root, I can't boot into recovery via an app.
What did I do wrong?
EDIT:
Okay, it looks like TWRP isn't working properly. I tried "adb reboot recovery" and that got me to a dead Android icon and a "No command" message. I have no idea why TWRP isn't working.

to confirm, have you verified you are using the correct TWRP version for your V20?
in this step "fastboot flash recovery twrp.img" is your twrp image that you saved, named twrp.img? If its not, that command won't work correctly.
usually after I flash recovery, when still in the recovery menu, i choose reboot recovery just to make sure it did stick. If it reboots back to itself, then try rebooting the device, and again confirm with manually entering recovery. Maybe overkill but it works for me LOL.
Good luck!
I am in need of big help! I made a critical error after days of trying to navigate the minefields of rooting my device. I have a LG V20 h910 and it is no one-click wonder root. It made me work for it and I finally got it. I loaded LineageOS 14.1 and all was good until the USB OTG cable from my PS4 controller did not register anymore. Damn, that was a let down, and probably led to my careless move of needing to downgrade my TWRP, saw the version I needed, forgot these are device specific, and now I'm stuck in a hard place.
Perhaps the fix is easy, but I have not found the answer after many, many searches...
I had TWRP 3.2.1-2 and needed to downgrade to 3.2.1-0 to try SuperRom (hoping it would have OTG ability). I hastily grabbed the first TWRP 3.2.1-0, threw it on the SD card, wiped everything except internal storage, and flashed the img, and did a reboot. Road block went up.
I tried getting back into recovery, did the PWR and DOWN pressing combo and got the Factory Reset screen, but after clicking "Yes" to both, instead of getting the TWRP screen, I got this error screen (attached).
I tried another idea - hooked it up USB to my PC and tried accessing it via adb/fastboot. I tried multiple drivers for my device, but no adb and no fastboot devices were ever found. The only thing that almost worked was booting phone into FASTBOOT mode by holding DOWN btn and plugging in a USB cable attached to PC. Once in FASTBOOT mode, My PC at least saw the ID for fastboot device. I tried to flash TWRP via fastboot, and it looked like it would happen, but in the end there was no phone screen response to my attempt, and the cmd window on my PC would get stuck and just hang.
Can someone please advise me on how I can fix this problem?

Dont reboot the device after flashing recovery in ADB. Boot straight to recovery.
Can a mod please move this thread to the proper location?
This thread should be moved to the q&a section

but can u tell me how to reboot straight to recovery while finish flash recovery in fastboot mode, i can't find way do this.
I have unlock the bootloader so each time i boot up the phone, first there is a lg logo displaying for about 2 second and then a warning msg will appear on the screen. this warning message will display on the screen for about ten second and then a lg logo appear again then boot the android system. i don't know how to interrupt the normal boot process and get into recovery manual.
when i use adb to reboot to recovery, lg recovery will appear after the warning message screen off. i turnoff the phone and press power+down button together to try to get into recovery manually, but after the lg logo appear the second time, there is no way to start recovery. the phone will boot to android directly.
ok i find the way to get into twrp now by vidoe in youtube.

Also having this problem, however when I hold the POWER+VOLUME DOWN buttons to try to boot into recovery after shutdown/battery removal - the system STILL loads.
I get the warning saying the bootloader is unlocked though. After that the phone just starts up as normal, even though I'm holding the buttons

here is the step i find finally
1. re-boot into fastboot mode
2. flash twrp use fastboot command.
3. power-off the phone
4. power-on with power and volume down button holding
5. while lg log appears, release power button immediately for 1 second and then hold again
6. when recovery selection screen appears, select 'yes' both two times.
now phone boot to twrp recovery.
REMEMBER: WHEN YOU BOOT INTO LG'S SYSTEM AGAIN, YOU WILL LOST TWRP. IF U WANT TO USE TWRP AGAIN, U MUST RE-FLASH TWRP AND REPEAT THE STEPS ABOVE. THIS WILL LOST ALL DATA(PHONE WILL GET FACTORY RECOVERED)!!
I hope this can help you, good luck.

You need to delete the file recovery-from-boot.p in /system
Each time you boot, that file gets executed and restores the stock recovery from recoverybak. Alternatively, you can flash TWRP to both recovery and recoverybak.

Hi, hope you can help solve the problem that happened with my Moto E4 "woods". Installing TWRP recovery (TWRP-3.2.1.-0_woods_UNOFFICIAL.img) went smoothly via ADB fastboot flash recovery etc. The phone rebooted however in "Orange State- your device has been unlocked and can't be trusted". Having searched the internet the solution seemed to be to prevent the phone from installing it's own recovery again by getting it to reboot via ADB with the command "fastboot boot ....recovery.img (the name of the TWRP image). It does so succesfully by first downloading "boot.img" and then the same thing happened as before, it boots into the unlocked orange state warning. The phone still has the stock rom on it and will boot into that normally once I've removed the battery and put it back in. But I have no recovery at all now, not the stock recovery either. Pressing volume down and power gets me into adb connection, and volume up into the warning. Any solutions? Anyone else had the same problem? Thanks!

When you're in bootloader, keep pressing volume button until it says recovery. Then tap power. If you already fastboot flashed recovery, no need to fastboot boot recovery recovery.img. just boot to bootloader and tap volume until you see recovery, then tap power.

Thanks for your reply and thinking with me, but like I wrote, all there is left is the option to use ADB. Pressing volume up and power no longer gets me into a choice menu, only a black screen with small white letters telling me to attach a cable.
No tapping whatsoever will change that. Volume up gets the orange state message again. So....
You need to flash the old recovery first ....from one of my threads ..follow full guide by flash no dm-verity ..THEN install new recovery via old twrp recovery ...the "NEW" recovery has errors so be warned :good:that will work
Go look in one of my guides for woods for old files

Thank you for taking the time to help out! Today I somehow got lucky after I reflashed it again, after having spent the morning deciphering the Chinese recovery which occasionally appeared. Rebooting into recovery inside TWRP held it stable. I manage to flash one custom rom, Dot Os, the Lineage OS for Moto E4 Woods got a TWRP message the zip wasn't correct (though I trust it was) and my backup made by TWRP did not restore. Is this what you mean by the errors? Very lucky to have a working Dot Os, and maybe I'll wait until an official TWRP is available now. Since I lost it again by forgetting to flash SuperSu again at the install of the custom rom....
Will look through your posts to find the guide with the files to have them at the ready Happy New Year's Eve!

twrp for 1762 ?
I can't seem to find TWRP-3.2.1.-0_woods_UNOFFICIAL.img annywhere on the internet
I found this but i don't realy trust that site.

Uninstalled magisk and the screen is black, only vibrates when pressing power button or the right side of the screen. I don't even know how to turn off the phone. I was able to do it because the warning of the bootloader being unlocked appears. How I can flash stock rom? abd won't recognize the phone.
I saw https://forum.xda-developers.com/oneplus-6t/how-to/tool-6t-msmdownloadtool-v4-0-oos-9-0-5-t3867448 this while searching but I'm scared since it locks the bootloader after.
Thank you

Can you get into fastboot? Hold down both volume buttons together and see if you can force your device into fastboot mode. Then from there, get the TWRP img file and use fastboot to boot the image, then flash the stock OOS rom, either from TWRP install option or with adb sideload of you're comfortable doing that.

I can, could you link me to a tutorial how to boot the image? I got it already, but unsure of how to proceed. Many thanks!
edit: now when I connect it to the PC it stays on the warning that the boot loader is unlocked
Now I was able to start TWRP but I still don't know how to send the file to the phone;
ADB recognizes the phone when TWRP is running
I think it's solved, thanks a bunch!
