[Oppo Find 7 and 7a] brownboy1289:
In this guide, I will show how to how to change from LVM to Chinese unification storage method. Windows OS Only.

This guide is specifically for Oppo Find 7(A/S).

The idea of changing to chinese unification storage method is to have access to 8.1 Android operating system and future Android OS builds.

Please follow these following steps in order be able to run 8.1 Android on your OPPO Find 7.

1) Back up only your internal storage because after you flash the following tools, the internal storage will be wiped completely.

2) Download this file (for OPPO Find 7s) and this file (for OPPO Find 7a) then run the following steps:

Extract the files, and locate the QcomMtk_Driver_Setup.exe (*install this driver*) and reboot your computer system.

After rebooting, take off the battery off the Oppo find 7 and press the volume up button and connect to the PC using a micro USB cable. Go to the device manager, open the ports tab and there should be something like qualcomm etc. If there is no warning sign then you are fine and you should proceed along the steps. If there is a warning sign, just right click on the driver and update by letting windows finding the appropriate drivers.

Then go back to the folder where you extract the zip file and locate (X9077_Android5.0_32G_20150520.exe) or X9007 respectively and run as administrator. rights only.

Now, the software should do the rest so please be patient and wait until the green line has finished and the timeclock down on the bottom right as come to a halt.

After the green line has finished, please remove your device and plug back your battery. Let the device fully boot up before moving on the following steps.

After you get to the setup screen. Press and hold the power off button and shutdown fully before going back to the fast boot mode by pressing volume up and power button at the same time, the battery needs to be installed this time.

Now, flash the twrp modded image using fast boot flash and download the two files fastboot and twrp-modded img :

1) Have your phone in bootloader mode. (Turn off your phone, press volume up button and power button together and connect usb).

2) Navigate to the folder and click on the top left of the folder and copy that. e.g C:\Users\samgi\Desktop\platform-tools

4) In cmd type in: fastboot flash recovery image-modded.img

4) Remove USB and press power button and volume down button simultaneously.

-After you have flashed the recovery, boot into recovery and store the ROM, GAPPS and cm13 unified patch in the external sd card using your USB.

Download your favourite 9.0 ROM:

crDroid for example: https://androidfilehost.com/?w=files&flid=262369

Install GAPPS (only pico):

http://opengapps.org/

After you have downloaded all the files rom gapps cm13 patch etc. Make sure to flash each of the zip files one by one:

1) Flash ROM

2)Flash Pico Gapps

3)Flash CM13 Patch here

So basically, just head over to https://download.lineageos.org/find7 and download the latest Lineage OS 16 ROM. Then download the MindTheGapps (since pico OpenGapps can't work) from https://androidfilehost.com/?w=files&flid=170282 make sure to get 9.0.0arm.

Reboot to recovery, wipe the dalvik, system and cache. Then proceed with installing the the LOS 16 ROM. After that, you can flash the CM 13 patch and the gapps (MindTheGapps). It's ok to do gapps first before the CM 13 patch. I noticed that it makes no difference. Works the same every time.

Well, that's about it, reboot and enjoy. OTA should work after this. I think.

Good luck.

Then, simply clear cache and boot to your 9.0 OS. P.S don't forget to restore your data that you deleted in step one. :P

Optional: If you want to go back to Color OS or you have hard-bricked your OPPO Find 7(A/S) this tool will help you get back to stock firmware.

This will check if this guide is applicable.

Note: Make sure your device has at least 70% battery. Charge it for an hour or so if you are not sure about the amount of battery left.

Note 2: I'll assume you are an admin of the computer you are using.

1) Disconnect your device from your charger/computer, etc.

2) Take out the battery and wait for 5 seconds.

3) Put the battery back in, hold the Power+Volume Up buttons and plug it into the computer.

4) Release your hands, and go to Device Manager. (How to go to device manager below)

1.	Click the start menu

2.	Right click Computer (Right hand side)

3.	Click Properties

4.	On the left hand side, click on Device Manager

5) Under Ports, you'll see either QHSUSB_BULK or Qualcomm *blah blah blah* 9006/9008

If you don't see any of the three, you're doing it wrong (Probably).

If you're not seeing it, try connecting your device without the battery.

Next, we uninstall the drivers. Simple enough.

WARNING: This part is only for people seeing Qualcomm 9006/9008 in Device Manager.

1) Uninstall the driver. (Right click your device, then click Uninstall. If prompted, delete driver software too)

2) Unplug your device.

3) Take out the battery and wait for 5 seconds.

4) Put the battery back in, hold the Power+Volume Up buttons and plug it into the computer.

5) Release your hands, and go to Device Manager.

You should see QHSUSB_BULK, if not, you might be doing it wrong.

Now we install the proper drivers.

NOTE: You should be seeing QHSUSB_BULK in your Device Manager, if not you're doing it wrong.

1) Download the Find 5 Drivers and unzip the file anywhere.

2) Right click on your device showing QHSUSB_BULK and click on Update Driver Software.

3) Click on "Browse my computer for driver software", and select the folder in which you extracted the drivers to.

4) It will install automagically. If prompted, click on Install the driver anyway.

After installing, your device should say Qualcomm *blah blah blah* 9006/9008.

The moment all of you have been waiting for. Unbrick!

NOTE: Your device should be connected at all times.

1) Download the tool that will save you below.

2) Extract the contents from the zip file.

3) Open the .exe file with admin rights.

4) There should be a line that is visibly different from others.

5) If there is, click start and wait till that line turns green. (It takes a few minutes. Generally nothing should go wrong at this stage.) If there isn't, you're doing it wrong.

6) After the line turns green, unplug your device and hold the power button until you see the Oppo logo.

7) If all goes well, you should be booted to ColourOS v1.2.5i.

If everything went through smoothly, you should be unbricked and ready to brick your device again.
