Here is what the Shield TV stock recovery looks like. To access it press ALT+PRINT SCREEN+i on any USB keyboard until your console reboots, then press the same keys again as soon as the Nvidia logo appears. You should see a broken Bugdroid with a "no command" message. Simply hold the tactile power button for a few seconds, until the screen pictured above appears.
To navigate touch the power button and to validate your choice hold it down.
Personally, I find the fastboot root method a bit complicated. Wouldn't be better to just use this stock recovery to flash a rooted stock image via adb ?
If anyone is willing to try, please report your success here.
Fastboot is required because you can't flash the ROM without unlocking the bootloader first. Flashing from stock recovery would require a script, which AFAIK has to go in /cache which isn't writable until the system is rooted.
So if you put the full android 5.1 on and want to go back to stock Android TV, would selecting wipe data/factory reset revert back to stock Android TV?
No, you would also have to flash the stock /system image and possibly /boot.

install rom manager from google play and flash the recovery for my phone (at&t) doesn't make nothing.
release the volume down + power buttons and then press again at the LG logo to enter in factory reset menu doesn't work.
i think my solution is flash the recovery with odin or some other software but i didn't find any thread with instruccions and files to do that.
what can i do??
I had the same problem with rom manager. I had to downgrade my software build number from d80010q to d80010d (i think it was d) and then push the TWRP recovery image with adb. Could never get CWM to work. A bit of a hassle but there are very detailed guides out there.
use freegee app in play store to install twrp/cwm

I did a factory reset on m friend's nexus 7. I can access bootloader before because I flashed a factory image of Lollipop 5.1(4.4.4 before) then relocked it. But my friend decided to sell it and wants to erase everything in it so I factory resetted it in settings. But its already two hours and its still on erassing. I pressed vol up and power while on that screen and it is stuck on formatting data. I tried holding power button to power it off but instead it goes back to "google" logo then erasing screen. I tried powering down again by holding 10sec and after it goes black I immediately released power button and quickly pressed and hold it again together with vol down to access fastboot mode but it goes to google then erasing again. Anyone has a solution? My friend will surely get mad on me and it is already out of warranty. I never happened with my Nexus 5 before

Hi, a while back, i tried following a loose guide on this forum, trying to root my Tab A T150. I cant really remember what steps i took or what my actions were but, I remember getting TWRP to run, but being unable to read the file system and also being unable to flash anything using TWRP. I then proceeded to reboot my device, only to get greeted with this screen

repeated by a shutdown loop with this screen, no matter what button combination i tried, i could not get it to display anything else. I am just looking to get back into android OS. I don't have any firmware backups but it should have been the latest firmware version.
Plug the cable into the PC but not the tablet. Turn the tablet off. While pressing both vol up and down, plug the cable into the tablet and wait for the green screen. Follow the instructions to relock the bootloader. That should reset the tablet, delete TWRP and put you back into the stock ROM.
What you probably skipped the first time around was formatting the data partition. Not wipe but format. That removes the encryption from the data partition and allows you to flash a custom ROM. You need to do that the first time it boots to TWRP.
Hi All,
I am trying to un-brick an Android DVR from Chinese manufacturer. Currently, it is stuck in boot and shows "Android is Upgrading. Optimizing App 1 of 1" on the screen. Can't get into recovery mode to clean cache or factory reset using reset button.

I tried to use adb to wipe the data but get permission error.
Last thing that appears to work is unlock bootloader from fastboot using the following commands:
Code:
su
adb reboot bootloader
fastboot devices
fastboot oem unlock
View attachment 4957257
The DVR is asking to press volume keys to accept the adb command and unlock the bootloader. However, there is no volume key in the device. I have just two keys, one power and one reset.
Can someone advice how to simulate volume key press to unlock the bootloader. Note that I am not able to get into the device at all due to "android is upgrading" error.
Hi to everyone. I am new to XDA. I have a problem with Tab 4. My friend wanted to flash custom rom but he is noob about this. So I took the tablet and flashed the custom rom with TWRP. Everything went smoothly until it is stuck at Samsung Galaxy Tab4 screen. I attached the photo where it was stuck. I want to boot into recovery but sadly, home button isn’t working at all. How can I boot into recovery? Please help me ASAP. I can’t do anything to it now. Sorry for bad English.

The tablet is bricked. After flashing twrp, there should be a message in the top left of the screen about set warranty bit. The picture you posted is missing the yellow text. That's bad. Try putting the tablet in odin download mode by holding the home and volume down button plus power. Then press volume up when prompted. If you can get into odin download mode, reflash the proper twrp and try again.
If you can't get the tablet into odin mode, jtag recovery is the only option, a very complicated procedure.
