Here is the PAC File Firmware for Cherry Mobile Flare J1 V4.0 Stock Rom and with android 5.1 lollipop operating system, this is the default version of this flare J1 v4.0 that can be update to 6.0 Marshmallow. Flare J1 V4.0 has a Spreadtrum SP7731 chipset that can be flash through SPD Upgrade tool.

Due to high many users looking for this firmware, I decided to share it without testing, this firmware is on beta so your feedback is needed, before you continue flashing I recommend to perform a backup first for safety purpose, back up first your orig firmware and NVRam, Performing those back up need a Chinese Miracle 2 box or NCK box, and if you don’t have that and you have no choices, you can also flash it then we encourage you to feedback by commenting below.

  2. Open your extracted files and run ResearchDownload.exe, For lower version open Bin folder and run UpgradeDownload.exe.
    NOTE:
    UpgradeDownload and ResearchDownload is the same, UpgradeDownload is just the name of the lower version but they are both SPD Upgrade tool.
    UpgradeDownload.exe
  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.

  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. you can search a procedure in google.

  12. On the off chance that you are as yet preparing Mastercards with gadgets that are obsolete, with wires running everywhere of business, you certainly need to move up to a remote Mastercard terminal. Our reality turns out to be more wire free each and every day, as more current innovation is created and used.
