linux mint xiaomi redmi 3 pro upgrade to MIUI 8
I bought this phone around 3 months ago. first I had a lot of problems about menu and applications. some chinese some english. some utf problems in applications. anyway I was reading this miui 8 update
then I decided to upgrade mine too. but I am a new in this flashing rom or any adb commands. first I downloaded recovery image then put the image in phone try to update from updater app inside phone it did not work. then I tried to use TWRP and fastboot method. I had problems about giving root access to twrp. then tried to use miflash but my machine is linux mint. so it did not work too.
I tried every online tutorial and could not upgrade my phone. at last I was reading shell scripts in fastboot package
flash_all.sh
flash_all_lock.sh
flash_all_lock.bat
flash_all_except_data_storage.sh
actually I was not sure about these commands
fastboot $* getvar product 2>&1 | grep “^product: ido”
if [ $? -ne 0 ] ; then echo “Missmatching image and device”; exit 1; fi
fastboot $* flash partition `dirname $0`/images/gpt_both0.bin
fastboot $* flash tz `dirname $0`/images/tz.mbn
fastboot $* flash sbl1 `dirname $0`/images/sbl1.mbn
fastboot $* flash rpm `dirname $0`/images/rpm.mbn
fastboot $* flash aboot `dirname $0`/images/emmc_appsboot.mbn
tried first line manually but fastboot command not found. I check apt repo and installed it with
apt-get install android-tools-fastboot
then first line worked
ido_xhdpi_global_images_6.8.11_20160805.0000.29_5.1_global # fastboot $* getvar product
product: ido
finished. total time: 0.001s
then run the shell script
ido_xhdpi_global_images_6.8.11_20160805.0000.29_5.1_global # ./flash_all.sh
ido Fastboot Tool Ver 5.0
product: ido

it took around 20 minutes for my phone to reboot. now I have miui 8 and this time all google apps included in this rom. I start using it directly without installing google apps. normally google apps was not in xiaomi redmi 3 and took me a while to understand. because normally in lg or samsung I never had system like this without google play store it was really hard to use. btw I ran those commands with root. I did not want to configure usb related access rights.
