Flash Pac file Stock Rom

  1.  Download the SPD_Upgrade_Tool_R4.0.0001 latest version, or SPD_Upgrade_Tool_R299015 lower version. Then extract to your desired location.
  2. Open your extracted files and run ResearchDownload.exe, For lower version open Bin folder and run UpgradeDownload.exe.
    UpgradeDownload and ResearchDownload is the same, UpgradeDownload is just the name of the lower version but they are both SPD Upgrade tool.
  3. In this instruction I will use UpgradeDownload and a Use Cherry Mobile Pac file as a sample. In UpgradeDownload window, click on single gear icon to Load Packet and browse for pac file(firmware/stock rom) you downloaded then click open. follow this screenshot.
    UpgradeDownload Load Packet
  4. Loading a pac file may took long depend on file size. After loading a pac file, now ready to start flashing, You can also click on Settings on two gear icon if you want to unchecked some part of firmware like EraseRuntimeNV, This will not work on lower version. I recommend that leave it unchanged if you don't have any idea.
    UpgradeDownload Start Downloading
  5.  Turn off first your phone, remove battery (if removable) then bring it back. In ResearchDownload/UpgradeDownload Click on Start Downloading, then in your phone press Volume up and Volume down then connect USB cable. If you see a a progress bar, then it means that it is successfully connected. if not, then try step 5 again.
    UpgradeDownload start

  6. Wait until you see a Passed in progress, that means, you installed a new stock rom successfully.
After you flash the firmware, you can now turn on your phone, take note that first time start up may took long. but if it tooks more than 15 minutes then I suggest to perform a hard reset.
