Kindle Fire HD7 X43Z60 tate
D025 seems to be 16GB.

I do not know the history of the device.
I got it at a swapmeet.
Stuck in a TWRP boot loop.

I have no idea what I'm doing.

I built a factory cable and followed this tutorial:
1. adb reboot bootloader (then in Fastboot mode) IIRC, I didn't have to do this, factory cable put it in fastboot.
2. fastboot -i0x1949 flash recovery philz_touch_6.48.4-tate.img
3. fastboot -i0x1949 boot philz_touch_6.48.4-tate.img
_______________________________________________________________

Now it boots and seems to be working.
TWRP seems to be gone.
It claims to be Cyanogen 13.0-20160214-UNOFFICIAL-tate.
Android 6.0.1
kernel 3.0.72+transi@transi-THINKPAD-T60#1
I had to replace the camera app and the launcher to make it
usable. Seems to do what I want.

Problem now is that battery drain is high in sleep mode.
I don't have any problem with working battery life. I'd just like to
be able to let it sleep for a few days and still have some battery left.

Battery is down ~50% in 24 hours of sleep.
The slope of the graph suggests that it's a constant load.
The "what's using the battery screen"
says it's almost all ANDROID OS.
Awake seems to be ON even in sleep.
On my other devices with stock ROMs, awake is OFF in sleep.
Everything else is very small.
In particular, wifi is about zero. Screen is about zero.
This does not appear to have anything to do with wifi.

Is there a fix for this? Configuration change? Different ROM?
Standby battery life is more important than the latest update.

There are literally thousands of pages on XDA about the battery problem,
but none seem to be specific to tate. Android nomenclature is not very
clear. It's difficult to determine exactly what applies to tate.
I've already turned off everything I can think of.

Problem is that the threads span 5 years. They start out with "this works"
and typically end with "this will permanently brick your tablet if you start
from the wrong state." Since I'm already at Cyanogenmod,
I'm assuming that's not an issue. Is that true?

I have no idea what I'm doing. I'M AFRAID TO BRICK IT.
I'm assuming that all I need to do is fastboot -i0x1949 boot philz_touch_6.48.4-tate.img
with a different .img file and leave the recovery alone. True?

If there's a fix, I want it. If not, I don't want to be trying every version
of ROM and risk breaking it.

Can anybody share a known working sleep power drain fix for tate that's safe for a newbie
to attempt?

Thanks,

Not sure what the battery drain is here dude, mine's the complete opposite. I can have it in standby for up to 5 days and I'm running the latest resurrection remix rom.

My galaxy tab 2 on the other hand..... That's crap.

Are you saying that you install it on a Kindle Fire HD tate?
If so, can you point me to the correct version to install?
Thanks, mike

Thanks,
I never got anywhere with resurrection remix . On boot, it offers me two options for launcher, but neither
does anything. I'm dead in the water, stuck in the select launcher loop.

I did finally find BeanStalk-6.25...-tate
Everything seems to be working with OpenCamera
and standby consumption is very low.
I think I'm good to go.

I played with LineageOS. I liked it, but never could make the camera work.
Also had some issues with SAMBA shared files on my windows network
using my favorite File Expert HD,
but TotalCommander made that work.
