nexus 7還原出廠Android 4.3，順利OTA，解決writing "radio"... FAILED (remote: (BadParameter))-適用NEXUS7 2012 3G版


前置Windows安裝驅動程式，以及如何unlock本篇不再多敘述
請查閱網路各資訊

本篇僅適用NEXUS7 2012 3G版
(1)下載檔案版本:android 4.3.0
(1-1)印象檔名稱:nakasi-jwr66v-factory-d341d356 (自行搜尋下載)
(1-2)radio_update.zip升級檔 下載點: http://globula.arctablet.com/Nexus7/radio_update.zip

注意：
只有jwr66v的版本的bootloader-tilapia-4.23.img可以透過fastboot燒入進去，除此之外其他的4.23透過fastboot燒進去會失敗

(2)抹除所有資料以及燒寫bootloader
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-tilapia-4.23.img
fastboot reboot-bootloader
fastboot flash radio radio-tilapia-1231_0.18.0_0409.img

(3)出現問題:radio燒不進去，FAILED (remote: (BadParameter))
暫時不管，先燒入別的印象檔
解壓縮image-nakasig-jwr66v，取出boot.img、system.img、recovery.img、userdata.img

fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
