Hi - my Nvidia shield K1 was suffering from battery drain issues after the latest updates to the point where it only showed as having an hour or so of run time from 100%. I followed a video guide and managed to successfully unlock the boot loader and downloaded earlier official recovery images from the nvidia site. I used various programs and successfully flashed the image over to the tablet. However, when the tablet reboots and goes to initialize and run for the first time after flashing i encounter the following problem; the screen turns on and a grey box appears with 'Android is starting' in and proceeds to 'optimising apps (number) of 114' (or whatever the number of apps is). This completes then the tablet goes to the android, Nvidia logo screen and stays on it for a few minutes before returning to the 'Android is starting' box again and re-optimising all the apps again before going again onto the logo screen. I tried with the 1.5.0 and 1.4.0 images but had the same result from both.
Can anyone help me with any suggestions of how to stop this boot loop and which recovery image to use that will take my tablet back to a time when the battery life was high again. Thanks in advance

The unit has been used for about 2 months and remains quite new. It was quite stable before. Yesterday night, about half an hour after plugged in for charging and with WiFi Hotspot turned on for sharing 3G data to another netbook, the unit suddenly rebooted itself. It then stopped at the start-up screen and remained there for several minutes. I kept holding the power button for a few seconds to turn it off but it then automatically reboot itself afterwards, and stopped at the start-up screen again. It means that even complete turning off is not possible.
Trying to enter into recovery mode showed the following few lines:
# MANUAL MODE #
-- Updating application...
Copying Common Apks.
Click to expand...
Click to collapse
and then it automatically rebooted again. It means that it can't enter into recovery mode normally.
It was possible to enter into download mode. And it was the first time this machine went into download mode. I run Odin Downloader and flashed the official stock ROM. After showing "Pass", the device rebooted itself. Unfortunately, it still stopped at the start-up screen, just showing "Samsung Galaxy Tab 7.0 plus". It is really troubesome. I have experience playing several Android devices before and it is the first time I face such troublesome problem.
The device is an official product. The biggest problem is that the original purchase invoice was lost and most likely that I couldn't get official support, repair service or replacement.
May I ask if anyone would kindly provide me some help or advice. Thanks!
Instead of going into download mode go into recovery mode and see if there are any errors. Your scenario is sounding very similar to the one I had in the past.
I just ran into a nasty snag at boot logo as well. nandroid, stock kernel and factory reset were no help. Try Odin back to Stock, it still may not get past boot logo, hold vol up and power to get into recovery and factory reset. Hope it works for you.
Unfortunately I was unable to get into recovery mode even after odin flashing stock ROM.
It rebooted itself a few seconds after displaying some lines of text. I can't see the normal recovery menu.
So I decided to try to flash Zombie-Pop today and everything went fine during installation but when the tablet started booting up it was stuck on "android is starting.." and it seems to load the apps. I knew it would take a bit of time to stabilize so I let it run but after 1 hour of it stuck there, I tried to reboot into recovery but I get a black screen and I can't access TWRP. It just boots right back to the android is starting screen. It doesn't seem to be a boot loop since it finishes the boot sequence. My biggest problem is not being able to access recovery because of the black screen which apparently is happening to some people with TWRP. I tried to go through adb but since my tablet isn't done installing, it doesn't have the drivers to run adb. Is my tablet toast? bricked?

Which bootloader are you on?
How are you trying to boot to recovery?
Hello XDA!
This morning, I attempted to flash Cyanogenmod 12 (CM12) onto my Google Nexus 6 using this youtube tutorial that I cannot link in this post, because I am a new member. The title of the video is "How to install CyanogenMod 12 Official Lollipop on the Nexus 6" It can be found on youtube.
Whenever I boot up the phone, it shows the "Google" screen. then the Cyanogenmod boot animation appears. A white popup shows up saying "Android is Starting Up. Finishing Boot" The entire screen then comes to life with cyanogen's default background. Finally, an error message consumes the screen saying "ENCRYPTION UNSUCCESSFUL. Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible. To resume using your phone, we need to preform a factory reset. When you restore your phone after the reset, you'll have an opportunity to restore any data that was backed up to your google account." The only button shown on the screen says "RESET PHONE". If clicked, the phone reboots, but before it can boot it gets stuck loading the TWRP Recovery application. What happens is, it'll show the TWRP logo, then the screen will turn off, then it'll show the TWRP logo again, then this loop will repeat endlessly. The only thing that I could do was reboot the phone into the boot loader by holding down the power button, and the volume down button. From here, I attempted to boot into recovery mode. The same thing happens, the TWRP screen loads, then disappears, and that just repeats itself endlessly. I also tried to preform a factory reset, but that didn't work.
As you can see, I really need some help.
The encryption failing may be caused because I came off of a custom ROM where I had the phone's encryption disabled.
THANK YOU VERY MUCH, and if I can provide any information, please ask.
Hi everyone.
I have a ASUS TF300T for over 10 years now. It is an awesome tablet and the last 4 years it has been my daughter's playing buddy. Around 6 years ago, as the performance of the tablet was horrible, I started to inform my self of what I could do to have a usable tablet again and that was when I found out about custom roms. So I did my research, unlocked the bootloader, installed TWRP bootloader and flash Timduru's ROM to it. It worked like a charm. Great performance and usability for the almost dead (thanks to ASUS) TF300T. Around the time Timduru's last ROM for this tablet was released, was also the last time I upgraded the TWRP to the latest version which I don't remember its version. Now to my problem... Last week my wife told me she couldn't get the tablet to work. As I looked at it, what I saw was the ASUS logo (with the device is unlocked at the top left corner) and then the Timduru's logo comes up and hangs, after a while it reboots to the ASUS logo again and just does everything the same over and over again non stop, can't even shutdown the device. If I hooked the usb cable to a PC it does the same but after 6 reboots the device shuts down. Then I tried to enter recovery so, volume down and power it on, the menu comes up as normal but now I tried to enter TWRP. Splash screen appears and reboots to the ASUS logo again. Then Linux pinguins show up at the top left corner and enters again to the TWRP splash screen and reboots. Now that's where I'm stuck at. Can't do anything. Volume down and power up don't do anything either, it always goes straight to TWRP recovery and reboots again. In the PC the Android device shows up until the tablet restarts again. Also tried adb but it always stalls or gives some strange info until the tablet restarts again. So my question is... I anyone able to help me restore this back to funcionality? My daughter would really appreciate your help guys! Thanks!

Hi there, I'm sorry for my late replay, because I'm not often been looking up here. Here is my advice:
The only way to get out of the loop you should do a "Buster99" to get back on Stock Rom Jelly Been 4.2.2. After that you'll be able to install the CR again. Therefore you should look up all my posts within this thread over the years. There you'll also find the right links leading to Buster99. Don't forget you need "Minimal ADB and Fastboot" to do a Buster99.
All the best and good luck, ebonit
PS: Here is the link to the Buster99 solution: https://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Hi all,
before starting to read my thread you can directly start by watching a video of how the device is acting.
Link to the video: Video
++++++++++++++++++++++
I own a Eonon GA6150 device with Android 5.1.1, RK3188, MTCD.
On the stock ROM the device randomly rebooted so I decided to install a custom rom made by Malaysk (Malaysk Custom ROM).
I followed the installation guide and everything worked fine. After booting up and landing on home screen, the device ‚crashed‘ and tried to reboot. Sadly only the car logo appeared and it couldn’t boot up properly (boot loop).
After that I booted into recovery mode and tried every step again. Since then the device is bricked(?). After starting the machine, all of the LEDs are working but the screen remains black. I also can‘t enter recovery mode, at least it doesn’t show up on screen.
Things I‘ve tried until now:
-Creating a bootable SD Card
-Open the case and check all wire connections
Is the device bricked or what exactly is the issue? And how can I fix this issue?
Look at the attachments for additional head unit information! Thank you in advance.
