This rom has a codec problemhello. The rom is working very well for me, but it doesn't work with hbo max, it stays in black screen and background sound. I don't know if I'm the only one that happens. Thanks
Yes, thought I disabled it but it came back.Anyone else getting notifications from seedvault? That never happened before.
No, only Fire HD8 2018
I lost my job because I hit the wall in the package garage by accident and didn’t tell my manager about it because I was scared . I learned my lesson about that.Looks like @Kaijones23 has logged in.
Long time no see.
If you're watching, I have a question: what happened to your job?
You are going to need to follow this guide (which includes downgrading to 6.3.0.0) to prep for installing a ROM:Is there any solution for "failed critical init step 4" error when rooting with mtk-su?
or a way to downgrade maybe?
I am trying to root fire HD8 2018 FireOS 6.3.1.4 in order to install LineageOS 20
You are going to need to follow this guide (which includes downgrading to 6.3.0.0) to prep for installing a ROM:
![]()
Fire HD 8 (2018 ONLY) unbrick, downgrade, unlock & root
Changelog: v2 - Fixed the issue with the screen Make sure to read this guide completely before starting. It requires you to open the tablet, however you don't need to solder or use any advanced tools. This is only for Fire HD 8, 8th generation...forum.xda-developers.com
You may have already done this, but did you turn the screen off and on once?Thanks for your reply. I already tried it but I was unable to get into the recovery after running "./fastboot-step.sh
The tablet gets stuck at Amazon logo and indicating "Recovery" in the lower left corner and nothing happens after that.
Anything else I can do?
I know this is old,NOTE: If you are on a firmware newer than 6.3.0.1, a downgrade is necessary, this requires bricking the device temporarily. (The screen won't come on at all)
WARNING: There have been numerous reports that would indicate a hardware-change that doesn't allow access to the bootrom.
When bricking these devices there is currently no known way to unbrick.
This makes the hardware-method currently the safest option.
I wish you well.Unbricking / Unlocking with Firmware 6.3.1.2+
If Recovery OR FireOS are still accessible (or your firmware is below 6.3.1.2) there are other means of recovery, don't continue.
If your device shows one of the following symptoms:
- It doesn't show any life (screen stays dark)
- You see the white amazon logo, but cannot access Recovery or FireOS.
If you have a Type 1 brick, you may not have to open the device, if your device comes up in bootrom-mode (See Checking USB connection below).
- Make sure the device is powered off, by holding the power-button for 20+ seconds
- Start bootrom-step.sh
- Plug in USB
In all other cases you will have to open the device.
Make sure ModemManager is disabled or uninstalled:
Code:sudo systemctl stop ModemManager sudo systemctl disable ModemManager
NOTE: If you have issues running the scripts, you might have to run them using sudo.
Also try using different USB-ports (preferably USB-2.0-ports)
Open the device and short the pin marked in the attached photo to ground while plugging in.
1. Extract the attached zip-file "amonet-karnak-v3.0.zip" and open a terminal in that directory.
2. start the script:
Code:sudo ./bootrom-step.sh
It should now say Waiting for bootrom.
3. Short the device according to the attached photo and plug it in.
4. When the script asks you to remove the short, remove the short and press enter.
5. Wait for the script to finish.
If it stalls at some point, stop it and restart the process from step 2.
6. Your device should now reboot into unlocked fastboot state.
7. Run
Code:sudo ./fastboot-step.sh
8. Wait for the device to reboot into TWRP.
9. Use TWRP to flash custom ROM, Magisk or SuperSU
Checking USB connection
In lsusb the boot-rom shows up as:
Code:Bus 002 Device 013: ID [b]0e8d:0003[/b] MediaTek Inc. MT6227 phone
If it shows up as:
instead, you are in preloader-mode, try again.Code:Bus 002 Device 014: ID [b]0e8d:2000[/b] MediaTek Inc. MT65xx Preloader
dmesg lists the correct device as:
Code:[ 6383.962057] usb 2-2: New USB device found, idVendor=[b]0e8d[/b], idProduct=[b]0003[/b], bcdDevice= 1.00
Compared to lineage 16 (when rm was first started) there is an increase of about 100 MB.How's the memory usage for everyone? I just noticed I'm using 1.3/1.4 GB on 20.0. Does anyone recall how this compares to the previous ROMs? Thanks.
If we added a high speed SD card and a kernel with Swap, we could increase the RAM tremendously. Im working on it...but am new to full buildsCompared to lineage 16 (when rm was first started) there is an increase of about 100 MB.
When launching an app that uses a lot of memory, try going to developer mode -> running services and stop the app.

outputs are just about the same. (Actually, if it's possible, it might be easier if you built the kernel and sent it to me to test. The only really important change is setting CONFIG_CFG80211_INTERNAL_REGDB=y
in whatever defconfig you're using to configure the kernel.)[eternitydragon ~] $ adb shell iw reg get
