<\/p>\n
3) enter “2” for download new firmware, and you will see available packages. I chose “5.0.0-RU1.1.124.zip”. Then it will start downloading.<\/p>\n
4) when the download is finished, enter “1. flash the phone”. The it is waiting for the device.<\/p>\n
5) Make sure your the battery is not low. When the phone is powered off, press both “volume down” and “power” button until the phone vibrates, and it shows “downloading”. (The words in the picture below is blurry because of the camera, but it actually reads “downloading”)<\/p>\n

<\/p>\n
\u00a0<\/p>\n
6) connect your phone to your PC at this time, and it will start upgrading. At one point, it will ask if you want to erase all previous data stored on your phone, you can choose y\/n based on your preference. And wait for a while, your upgrade is finished and you phone will be restarted. Notice that it will take pretty long time to start the phone for this first time because it’s configuring settings. Wait for about 10 mins, and you will enter the system.<\/p>\n

<\/p>\n
7) If you wait for more than 30min\u00a0and the screen stayed at “Powered by Andriod” page, basically your upgrade failed. Please read the second method to solve this problem.<\/p>\n

Method 2: Updating using Fastboot<\/strong><\/p>\nIf you have the problem described in step 7) in Method 1, mostly it’s because some packages were not delivered to your phone. To solve this, we will use Fastboot to flash the packages one by one.<\/p>\n
steps:<\/p>\n
1)\u00a0Find the folders where you put your “youtaphone_flasher.exe”, and open it.\u00a0It should\u00a0look like the following picture:<\/p>\n
![\"5\"](\"http:\/\/yingzhangdong.com\/wp-content\/uploads\/2017\/01\/5-1024x457.jpg\")
<\/p>\n
\u00a0<\/p>\n
My directory is “C:\\Users\\yd975\\Videos\\\u5237\u673a\u8bd5\u9a8c\u7530”, sorry\u00a0for the\u00a0Chinese characters here, but it’s just a name of the folder, you can change it to whatever you like.<\/p>\n
2)Right now your\u00a0phone stayed at “Powered by Andriod”.\u00a0Push “Volume UP”\u00a0button and “Power” button for 10-20s, until the phone vibrates.\u00a0Then it will enter “Andriod system recovery”. like the picture below. use volume up and down button to select “reboot to bootloader”, use “Power” button to confirm, and you will enter the “downloading” page like Method 1 Step 5.<\/p>\n
![\"IMG_0791\"](\"http:\/\/yingzhangdong.com\/wp-content\/uploads\/2017\/01\/IMG_0791-768x1024.jpg\")
<\/p>\n
\u00a0<\/p>\n
3) Connect your phone to your PC. In your folder where you put “youtaphone_flasher.exe”,\u00a0on empty place, hold shift and right click, select “open command window here”.<\/p>\n
4) Input the following command lines into cmd, make sure each command returns a result of “OKAY”.<\/p>\n
“Your directory” fastboot.exe flash aboot firmeare\/emmc_appsboot.mbn<\/strong><\/p>\n(for example: I put C:\\Users\\yd975\\Videos\\\u5237\u673a\u8bd5\u9a8c\u7530>fastboot.exe flash aboot firmware\/emmc_appsboot.mbn\u00a0\u00a0\u00a0 <\/em>Because my directory where I put my “Yotaphone_flasher.exe” is C:\\Users\\yd975\\Videos\\\u5237\u673a\u8bd5\u9a8c\u7530)<\/i><\/p>\n“Your directory” fastboot.exe flash boot firmware\/boot.img<\/strong><\/p>\n“Your directory” fastboot.exe flash system firmware\/system.img(<\/strong>Usually people will fail at this step, it is because system.img is too big a file for Fastboot to open. Use ‘”Your directory” fastboot.exe flash -S 500M system firmware\/system.img’. what this command does is split the system.img file into several small ones (each one is near 500M), and read them one by one.\u00a0If 500M file is still\u00a0too big for your Fastboot, you can set\u00a0it to 300M, 200M,100M, etc.\u00a0If that still not works,\u00a0usually it means your\u00a0Fastboot\u00a0is\u00a0crazily out of date.\u00a0You can find and download a new version of Fastboot on the\u00a0Internet and try the\u00a0previous steps again.\u00a0)<\/em><\/p>\n“Your directory” fastboot.exe flash recovery firmware\/recovery.img\u00a0\u00a0<\/strong><\/p>\n“Your directory” fastboot.exe flash cache firmware\/cache.img<\/strong><\/p>\n“Your directory” fastboot.exe flash modem\u00a0firmware\/radio\/NON-HLOS.bin\u00a0<\/strong><\/p>\n“Your directory” fastboot.exe flash sbl1 firmeare\/radio\/sbl1.mbn<\/strong><\/p>\n“Your directory” fastboot.exe flash rpm firmware\/radio\/rpm.mbn<\/strong><\/p>\n“Your directory” fastboot.exe flash aboot firmware\/emmc_appsboot.mbn\u00a0 <\/strong><\/p>\n“Your directory” fastboot.exe flash userdata firmware\/userdata.img\u00a0<\/strong>(sometimes this step fails, but it will not\u00a0affect the upgrade, so don’t worry about it.)<\/em><\/p>\nfastboot.exe reboot\u00a0\u00a0<\/strong><\/p>\nAfter you enter the last command line, which is to restart the phone, you phone will stay at the flashing logging in window for about 10min (Method1 step 6’s picture). Be a little patient and you will enter the new system.<\/p>\n

Conclusion:<\/p>\n
My main reference is from “felonwang”‘s blog. http:\/\/blog.sina.com.cn\/s\/blog_59cf67260102w33g.html<\/p>\n
He discussed the general steps and several interesting points. I feel honored to learn from his article. I respect and appreciate all his effort and work.\u00a0While, my\u00a0unique contribution for\u00a0my article\u00a0is:<\/p>\n
\n- I put up the details of how to fix the upgrading failure (“stayed on Powered by Andriod page forever”).<\/li>\n
- I put more details on how to\u00a0use\u00a0Fastboot to deliver each\u00a0package to\u00a0the\u00a0phone one by one.<\/li>\n
- \u00a0I researched and solved the problem of opening system.img<\/li>\n<\/ol>\n
It takes time to do research on internet and play around with my phone. But I got much happiness when it finally works. Good learning experience for me, and I hope this article can help people who are interested in this aspect and have similar problems.<\/p>\n
