O+ Crunch stock Rom
O+ crunch alndroid 5.1 lollipop
The Oplus O+ Crunch firmware is here, with the latest Android 5.1 Lollipop operating system, Here is a fresh back up from Chinese Miracle II aka CM2, This is a PAC file firmware that you can use any Spreadtrum flasher like Research download or Upgrade download, you can follow below instructon and download the firmware below tested and proven working through latest SPD Upgrade tool. The chipset is Spreadtrum SC7731.

Since my friend ask me for a lollipop stock rom and I tried to search in google and I can't find any stock rom so I decided to post this. so maybe this is the first in google search engine. Before flashing, take note that all your personal data in phone will be formatted including contacts, messages and all installed third party application. I recommend to do a back up first before proceeding.

We have different reason why we need to flash our Android smartphone, so what ever it is, I'll give you some list of common problem that can be solved through flashing Oplus O+ Crunch firmware, include the following;

  • Monkey Virus / Infected Virus
    This is a common problem for android smartphone, it can be popup some sexy pictures when you connected to internet, or some application automatically download without doing anything. Some problem also automatically enable data or WiFi connection even you turn off. that means that your phone has a monkey virus that even if you format or hard reset, it cannot be removed because it is installed in system, the solution is to flash new firmware.

  • Hang or Stuck in logo
    This is when you start up your phone then yes it start but you only see a android or a phone logo, the common reason of that is because or installing custom recovery or after you root or maybe because of viruses, it can be solve by flashing new stock rom.

  • Unfortunately error
    It happens when some of your application crush, sample is when you open contact it will popup Unfortunately, Contact has stopped. Other phone sometimes doesn't function because of this error, so the best thing you do is to download the firmware below and flash new firmware.

  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.
