If you use a Amazon Kindle Fire 2015 (45$) Generation „Ford“ or other Android Tablets,Smartphones you must know some MAJOR Informations about the Firmware Handling.
If you were asked by the Fire OS or Android to „Upgrade“ the Firmware OS, DON’T PUSH YES it without READING DETAILS! I prefer ALWAYS NO FIRST!
Use ALWAYS a SDCARD to hold the MAJOR Data of your Tablet, cause if bricked or damaged you can’t pull off the DATA!!!
Android Firmware Images INCLUDE not only the OS, it includes DRIVERS, and the MAJOR BOOTLOADER!! Cause Android Devices use no real BIOS!!
If you Upgrade, you can RUN into BIG TROUBLE! Broken Drivers like no WIFI connect, freezing Screens on Boot, or BRICKS like the „BLACK SCREEN of DEATH“ which destory the Tablets cause you can’t reach the BOOTLOADER for RECOVERY MODE and SITELOAD the FIRMWARE again!
UPGRADES to bigger Version Releases like 5.1 to 5.3.X CAN’T be DOWNGRADED! Cause the DOWNGRADE don’t force overwrite correctly the BOOTLOADER, or leave the NEW BOOTLOADER untouched which can’t find the old KERNELS Names!
As MAJOR INFO you should know that the „adb shell tool“ is a DEVELOPER TOOL which doesn’t ASK anything to confirm, if the Firmware File is wrong or damaged! It flashes without any testing and any protection check! YOU have to KNOW what you ENTER!
You can’t reach anything, if the Tablet is BRICKED and you can’t reach the RESCUE MENU MODE! Cause NAND Chips need a connect from adb shell tool to USB then to EEPROM Chip!
Plugin the USB Stick with the last Boot Loader, Power off and on the Box by switching the PSU Switch, PRESS + HOLD OK BUTTON if the old Loader Shows Revision Number on Display „15XX“ then the Bios starts flashing the new Loader and Reboots after 1-2 Minutes without any work by YOU!! On newer models Press + Hold OK, then the Screen Shows PRESS POWER Button to Flash! (Bootloader 16XX Handling)
After this Reboot, Power off, and change the USB Sticks and do the same work again, but to Flash NOW the „Openmips OS“ with enigma2.
If this is successful the Box reboot again, but now into Opemmips 5.4 (Blue/White Logo instead Red/White)
Change on a TV the Settings, HDMI Output, Language, Network Wifi, Satellite LNB and start Channel Auto Search
Go to System -> Software and add your wanted Plugins like „Openwebif“ Web Interface and „EPG-Refresh“ (AUTO Update Channel Lists)
Test the box and do A „Full Image Backup“ to a empty USB STICK!!
Power down the Box and Plugin HDD and 2nd. Tuner Cards, Power on and Test again
Do a FULL IMAGE BACKUP by the Interface to HDD (/media/hdd) too.
If you want to update the SSD Firmware of a device you should know some things:
Do you REALLY need the update? Bugs? If NOT exit here!
Firmwareupdates can destroy DATA on Drives!
Data cant be restored if the Controller fails after Update
Downgrade a Firmware to older is most IMPOSSIBLE!!
.. now you need a USB Stick 4GB and the ISO File of the Firmware Disk of the Manufacter then open the Gnome Terminal or Console and:
$sudo su - #become root
$apt-get update && apt-get install unetbootin gparted # install the tools
$dd if=/dev/null of=/dev/sdc bs=10240 count=1 # delete usbstick unmounted with zeros (factory reset)
$gparted /dev/sdc #create new Primary Partition with FAT32, set "managed flags" to "boot lba", now exit gparted
$mount /dev/sdc1 /mnt #mount usbstick to /mnt
$unetbootin #select FreeDOS at Menu, and select /dev/sdc1 and create the FreeDOS Stick, then exit unetbootin WITHOUT reboot!
$mkdir /iso && mount -o loop /home/yourusername/firmware-cd.iso /iso # mount the CDImage to /iso readonly
$cd /iso && cp firmware.img /mnt/firmware.img # copy firmware-data to usbstick
NOW, reboot and unplug other HDDs of the PC, ONLY the SSD must be insert!
Boot the PC on the usbstick, on the unetbootin Menu PRESS „Tab“ to get the „Unetbootin-Console“!
Here change the value of „initrd=/ubinit“ to „initrd=firmware.img“ and PRESS ENTER
Follow now the Firmware Update Dialog and Reboot with disconnected usbstick and replugged Drives…
