it's alive, it's alive \o/
So, here is my howto: What you need: hardware: - a x86 computer on GNU/Linux - a usb cable - a likebook mars with a battery > 80% (charge it before up/downgrading) softwares: - rkflashtool (ex: apt-get install rkflashtool, or here) - upgrade_tool version 1.24 (cf this link) - and the rk firmware image of android 6 (thx to bekar for the link, it may need a mirror link, md5sum of the image (unziped) : 493fcab93a9613978c7c0c5dfd102e6e) also you will need a terminal emulator on your computer (ex: xterm) with the correct user perms to access the device (ex: root) Make your mars back to life with a gnu/linux computer (with some non-free softwares ): - boot your computer - unplugged everything on the mars (usb, sd card, etc.) - unplugged the battery (or poweroff the mars if you see the screen and are sure of what you are doing) ; - replugged the battery - press "reset" button and keep it pressed - wait ~3 seconds (keep reset pressed) - plug the usb cable (keep reset pressed) to mars and your computer - wait ~3 seconds, then release the reset switch - open a terminal emulatior with the correct perms - test if your computer detects correctly the mars with the command line : "rkflashtool p" (see my previous posts ; it should print you some info like "CMDLINE" and then go back to the prompt. If not, like freezing or what, there is a problem, so verify that the usb cable can do data etc. restart the steps from the first unplugged) - use "upgrade_tool" to upload the firmware like this : "/path/to/upgrade_tool uf /path/to/the_rk_firmare.img" You should have something like that in the output : Code:
root@my.computer:/tmp/Linux_Upgrade_Tool_v1.24# ./upgrade_tool uf /tmp/T80D/t80d-456.img Loading firmware... Support Type:RK330A FW Ver:6.0.00 FW Time:2020-03-12 18:43:36 Loader ver:2.60 Loader Time:2018-07-16 23:37:33 Upgrade firmware ok. root@my.computer:/tmp/Linux_Upgrade_Tool_v1.24# - then the mars reboot automatically. From here I guess that you can unplugged the mars to your computer, I stayed with it until the end just in case - ~3 seconds later, a "loading" screen appears (the boot one) - then, later, like a minute or 2, white screen with some msg on the bottom like "mount /media (device not found)" with something like "formating data". Just wait, so far so good, it takes like 5 min max. - then, it reboots, you will see the loading screen again, just wait like 10 minutes maybe a bit more but the loading dots are moving so you know it is still alive. Then, it will ask the language to use for the interface of the mars, and all the basic configuration. And your mars is back to life! \o/ some things to know: - you need a x86 environment because "upgrade_tool" is a non-free software from rockchip and it is compiled for i386 : Code:
# file upgrade_tool upgrade_tool: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=7c7f75f253274e23523b1fe1267160b081967534, with debug_info, not stripped I've tried rkdeveloptool (a free software), etc, but it froze too at the same steps. I have tried the raw image given by rvcjew in previous post (thank you so much rvcjew for all your help! <3) but I haven't succeed to make it works, but I guess there is a way there too. So, no android 8.X or newer for the mars with a gnu/linux computer from my tests Maybe one day I will try again, but here it works fine for me right now. I can reed my books and I don't use Internet neither wifi on my mars (for privacy/security reasons), so… Last edited by prout; 05-19-2021 at 04:52 PM. |
