[UNBRICK] [ROOT] [TWRP] Fire TV 2 (sloane)

[vrl2]

ok. Yes Get twrp reinstalled first .

How I install the rom while in twrp is I copy the zip file to SD card. and also you should have a copy of super su .

Now take that micro SD card and insert it into your fire .
Reboot . while in twrp recovery


Go to wipe , select data

Now choose switch file system to ext2 , select format. use right bar button swipe to complete.
Hit back button , now select ext4 . format in xt4 format.

Hit back bottom .
Now go to install . select from bottom right of menu , install zip from,
select your external SD card from the menu .

choose the ROM file zip.

Select install .


When done , now go back ,select super su and install .

I would try to install ROM this way from micro SD card once you did the procedure to
Flash twrp .

Thanks for your guidance.
Unfortuantely the first step in installing TWRP -- sudo ./bootrom-step.sh -- keeps giving me the same error. It gets to "Clear preloader header" and then keeps failing with the same error message (attached).
This same script worked earlier, but since that inital success has always given me errors. Is this expected? Should I just keep re-trying?

bootrom-step.sh from amonet-sloane-v1.1 worked initially, and after running fastboot-step.sh from the same package, I was able to get into TWRP. However, after performing a wipe (the option that requires typing 'yes') I get nothing but a blank screen and a flashing light.

It may be that the eMMC of your box switched itself to read only... (most likely if it's a samsung chip).
Take a look into the new thread, there are some postings about dead eMMCs.

Thank you for your response.
In XDA forums the function to search within a thread seems not to work for me, so it searched all threads instead of a single thread. So there is not a way for me to go through all 30+ pages of posts in the new thread to find eMMC related posts. Is there a specific way of going forward in this case?

Looks like the short is working (I'm certain that the light is off when the short is in place). I have run it 15-20 times now. When I run bootrom-step.sh, it no longer works despite the initial successful run.

Sometimes I get to the point where I get the prompt to remove the short -- but it doesn't get much further. If I can get past the handshaking phase, then the furthest it gets is to "Check GPT" at which point it stalls at "Check GPT" with this EMMC read error:

File "/home/ubuntu/Desktop/amonet/modules/common.py", line 199, in emmc_read

It often stalls earlier (usually at either "waiting for bootrom" or if it gets past that, it stalls at "Clear preloader header" or "Init Crypto Engine")

@Sus_i is this the eMMC error that you were referring to? The U1600 chip is a Samsung, like you suggested. Is there any work-around or does this mean the device is dead?

Thanks.

Friend. Do you have modem manager disabled per instructions.
Did you remember to give the amonet folder with the files full root permissions with write
access .


I would also try the version of amonet Sloane that has gpx fix .

Run the gpx fix .

Then after that try the files again .


Its extremely important though that the folder of the files are given full root , and
write permissions. What I do is either in mint or ubuntu, in the amonet Sloane folder
I right click and go on properties ,then I give each file in that folder write access.


also make sure when entering commands to start the process that you begin with sudo

What happens at the time the script errors out? Does the LED start some flashing? Is the LED dark? What device can you see in lsusb just after the error message?

The problem is flashing these devices is not an exact science.
I also been there where your at , extremely frustrated .

honestly , my best advice is try everything any anything you can think of that might make a
difference. Also try the amonet Sloane packages that have those other files. Like the
Gpx fix . try the others also.

I feel for you cause we've all been there.

with the lights , I've had my boxes where no lights would show anything,
but the exploit still unbricked them.


if you can , I would just save yourself a headache and find one on ebay.
usually there about 25.00 , sometimes with shipping.

did you message the devs who made the exploit and files for Sloane ,
They can probably give you some detailed information that may help.


I'm trying to think , I know there was a file in one of those amonet Sloane packages that
resets the chip if your having problems .

definitely reach out to the devs friend.


sorry I couldn't be of more help .

Hey , did you try making another cable . sometimes it can be that also.


Chris.

Yesterday i did the unlock from scretch wiped everything ans installed the stock Image 5.2.7.2 plus magisk 23.0. But the image wont boot. All i get is the white Amazon Logo. Tried diffent stock roms. Twpr still works tho. BL is still unlocked. I came from prerooted image btw. Any ideas how to get out auf this? Is it a softbrick?

Edith: it was a hardware failure. Just to let you know

Anyone know why adb reboot recovery doesn't reboot to TWRP? I still have to input a right to get into TWRP.

This is the unbrick/root for the boxes with locked bootloader, TWRP possible via bootmenu.
You may flash the unlock via TWRP from here:

Then adb reboot recovery will bring up the new TWRP.
