2017 Fire HD 8 - GIZA -- Boot loop + Has Lineage OS on it.

[likwidchz]

Hello,

At one point this tablet was working just fine. It sat for a while and now it boot loops. Shows the amazon logo and auto restarts.
I can hold the proper volume up or down key and it says "Recovery Mode" on the bottom left but never enters into it.

Oddly enough I wasn't screwing around trying to do something I shouldn't have, but for the life of me I can't figure out what the deal is. Have anything I can try to possibly recover it? or is it straight to the bin.

Thank you in advance.
Take care,

Try fastboot boot recovery.img with the help of PC, if it boots format data and install rom.

Yeah good idea I'll report back .. I mean I can't break it anymore heh. I'm going to blame gamma rays coming down from from space and flipping a single bit in my 6 year old tablet............... causing it to boot loop.

So thinking out loud.

How do I get the tablet in a spot to accept a fastboot via USB?

It doesn't start up correctly to booted android. It doesn't enter TWRP... it seems as if I am stuck right?

What's happening when you try to boot into fastboot mode? After entering fastboot mode in cmd "fastboot boot twrp.img" "(drag and drop twrp file after boot )" it'll boot into twrp.

You will have to explain how I would boot it into fastboot mode if
1 The tablet doesn't fully boot up past the amazon logo.
2 I cant even enter TWRP.

What am I missing?

Thank you and cheers!

When the device is fully shutdown press volume down + power.or maybe volume up check your device's combination key

Hello apologies,

I'll try and be as verbose as possible this time

Ive had this execute once, but when it does it looks like it wiped out TWRP as I cant get the small text to appear on the bottom left hand corner of the tablet while it does a boot holding power and the volume button.

So I'm not quite sure what I can do now.

Is there a method to flash TWRP with fastboot? or is that what the recovery is?

Could you provide a detailed list of items to try out and some high level instructions.

I've been thumbing through https://forum.xda-developers.com/t/unlock-root-twrp-unbrick-fire-hd-8-2016-giza.4303443/ this guide, but realize I'm not sure which step I need to start from, so I have bene trying a bunch of things and kind of stumped.

Thank you Shiva,

Bootloops are definitely a hassle sometimes. On your device your can either play the button game , watching the device closely and holding the the right button combo when the device goes black in hope that the device will boot into recovery or fastboot when it starts the bootloop again. The easiest thing for me to do sometimes is wait for the battery to drain completely dead then plug the device into the computer while holding the button combination to enter fastboot or recovery. The crappy part is waiting for the battery to drain. I did do a google and learned that Giza uses vol down button and pwr button to enter recovery. But with a dead battery it's likely one will only need to hold vol down button while plugging in the device. If it's in a bootloop it's probably not necessary to hold power button as well, just need to hold the vol down button at the time. I will say with a fair amount of confidence that the device is not a loss cause. Good luck, hope you get it working.

I had a weird assumption that I had to wait for the battery to drain. Its just weird this thing happened when it was working just fine.. usually I know when I screw something up pretty good.

I'm more curious on what command I need to be running and constantly retry to load up TWRP via fastboot.

Thanks!

From what you have described issuing any command from a computer to the device wouldn't be possible as the device is bootlooping. I could not find any info on button combination to enter fastboot only recovery. from recovery there is a reboot to bootloader or fastboot option. that is your best bet. I have messed with at least a few different kindles in my time but there is always someone out there that has done more and may have another option they can add.

Nothing, I can guide you there flawlessly. If you concerned about privacy no problem.

I don't think you are the best person to guide on this one. You don't even seem to know what an Amazon tablet is, considering you suggested to fastboot boot when that cmd was patched back then in 2015.​

@likwidchz If you're able to access fastboot thru boot-fastboot, erase preloader with fastboot erase boot0, reboot and run bootrom-step.sh again.

Yes I don't know about this tablet, I thought it was just like any other tablets sorry

Would you happen to be on IRC or some discord group?


I have done about ~7 of these tablets Suez/Giza but when something goes south, its not clear to me which step I need to start back from. Having a side conversation might help. In the end of the tablet is done, I am not going to be too broken up about it. But it's not a lost cause yet.
Thank you for the assistance! Much love.

--Take care.
