STEP 3: Change to the OtterX partition layout

Reboot after installing TWRP for OtterX

Open the bootloader menu by pressing [POWER]

Use 1-2 SHORT presses of [POWER] to highlight "ADVANCED -->"

Use a LONG press of [POWER] to select ADVANCED MENU

Use 5 SHORT presses of [POWER] to highlight "PARTITION MODE: AMAZON" (if this is OTTERX you can skip step 3)

LONG press [POWER] to open "PARTITION MODE MENU"

Use 4 SHORT presses of [POWER] to highlight "[CONFIRM] SET MODE: OTTERX"

WARNING THIS WILL ERASE THE CONTENTS OF YOUR "SDCARD" and USERDATA!!!! Before doing this step you should have backed up ANYTHING IMPORTANT and pulled it off of your Kindle!

LONG press will select this option and your system, cache, userdata will be changed to the OtterX layout (and ERASED)

Now use short [POWER] presses to navigate BACK and then to "RECOVERY"

Compare your partitions, with what I posted in Started a Thread [How To] Fix OtterX Install Errors, Partition sizes, Unable to Mount System... with some possible fixes for those having issues since converting to OtterX, with pushing files, failure to mount system errors when installing Lollipop Roms...

Partitions all should say Present: Yes

System: Current file System: Ext4 - Size: 751MB (768MB)

Cache: _Current File System: Ext4 - Size: 503MB (512MB)

Data:__Current File System: _ f2fs - Size: 5820MB (5880mb)
[Kindle Fire Q&A, Help & Troubleshooting] xRick64x:
I tried this solution, but it didn't work. If you have Twrp 2.7.1.0 and bootloader 2.05, and have wiped cache, rebooted, Fomated Data, wiped partitions in wipe>advanced and still have issues:

Solution:

Reboot to bootloader, select Amazon partitions, select recovery, wipe cache, reboot to bootloader select OtterX partitions, select recovery, wipe cache, reboot, format data, wipe all partitions.

Verify Partition sizes match post #2

All partition say yes, but the sizes are:

System: Current file System: Ext4 - Size: 751MB (739MB)

Cache: _Current File System: Ext4 - Size: 503MB (495MB)

Data:__Current File System: _ f2fs - Size: 5800MB (5421mb)

The partitions look just like the screenshots you have on how to fix Otter X...: except for the numbers are different.

System: Current file system: ext4, size 751MB, Present:Yes, Used 12MB, Removable:No, Free 739MB, Backup Size 12MB

I have the cm-11, and the gapps in my adb folder.

I reinstalled the Kindle drivers just in case.

The KF is listed in device manager as Linux file-CD Gadget USB device.

I open up command prompt and type in cd/adb

I paste the code you gave me: adb push cm-11-20141112-SNAPSHOT-M12-otterx /sdcard/

adb push pa_gapps-modular-pico-4.4.4-20150308-signed.zip Then hit enter.

cannot stat ' cm-11-20141112-SNAPSHOT-M12-otterx' : No such file or directory

C:\adb>adb push pa_gapps-modular-pico-4.4.4-20150308-signed.zip With the cursor blinking after the zip.

I get a ton of script that I wish I could show you, then it just has C:\adb> waiting. No rom on the kf.

[Kindle Fire Q&A, Help & Troubleshooting] sukd:
otterx-u-boot_v2.05.bin is the bootloader

openrecovery-twrp-2.7.1.0-blaze.img is the recovery

It boots to recovery, but it does not go to the system, even with restoring the backup.

The USB boot mode in the recovery also does not work. It just goes to an indefinite loop and the adb

connection is not consistent. Sometimes it detects and again disconnects.

adb only works with recovery and since the system does not boot, I can't

do all the steps necessary to flash the bootloader and the recovery.
