INSTRUCTIONS

You are doing this on your own responsibility. I take no responsibility whatsoever.

(THIS WILL WIPE YOUR ONEPLUS INCLUDING INTERNAL SD)

Download both the files from above and extract them (WinRAR, WinZIP, 7ZIP etc). You should have 2 folders: "OnePlus2_14_A.19_160604" and "qc"

A. Install the Certificates followed by the Qualcomm drivers.
1. Open the folder "qc" and install the Test Certificate in the following Stores: Trusted Root, Trusted Publisher, Third-Party Root and Personal
2. Run the Qualcomm setup wizard (also located in the qc folder)
3. When setup completes, launch Command Prompt as an Administrator and type bcdedit /set testsigning on
4. Restart your computer. (Once it gets on, you should see a watermark stating Test Mode in the bottom right corner. If not, type bcdedit in Command Prompt as an Administrator to check if testsigning shows on. If not, repeat step 3.)
5. Turn off your phone and disconnect the USB cable from the phone.
6. Hold vol-up and plug in the USB(Do not press Power button). The screen will stay black but you will hear a sound from windows that a device is attached.
7. The driver should now automatically install. If not, go to device manager and right click "Unknown Device" and click "Update Driver" Search up the QC folder and press ok. The driver should now install. (Got the RELINK issue? Take a look here: http://forum.xda-developers.com/show...1&postcount=46)

B. Flashing Process
1. Open the OnePlus2_14_A.19_160604 folder and open "MSM8994DownloadTool.exe"
2. Look if your phone is detected in the list. everything is Chinese but you will see one row with different chinese text from the rest within the list. If not, recheck if driver is detected in Device Manager (If not, go back to Step A - Line 3).
3. First click the right square Chinese button. This will perform an integrity check on the downloaded files by verifying the MD5 hash values.
4. The system will seem to hang for a bit but should give you a pop up with the results of the above verification. When everything is ok. Press the start button. and let the progress finish. (If something is not ok, you will have to re-download the images. Google Drive can help extract only the necessary files.)
5. When it's done. Disconnect the USB cable and turn on the device.
6. Launch Command Prompt as an Administrator and type bcdedit /set testsigning off and reboot. Your system should no longer be in Test Mode.

C. Reset TAMPER Flag (Optional)

(This may potentially change your SmartPhone to a rather large paperweight and I will just laugh at you bearing no responsibility)

Finally Managed to get a hand on this after a late night session with OnePlus. Great that we now have the MM Stock Reset which should theoretically help to get back to stock regardless of the ROM, customizations etc.

I believe this is the best option to use to return to stock from CM.

Is it recommended to do this to make sure that the installation is well made?

I installed 3.0.2 via OTA but my battery life is mediocre(3 hours). I know that in my Samsung devices it was better to clean flash the room yourself rather than doing it via OTA but I don't know about oneplus 2.

Should I just factory reset it or maybe do this whole procedure ?(except step C)

You have a few options.
1. This threads Stock Reset option guarantees your phone will be Stock OnePlus, just as a new phone (Bootloader Locked, Recovery Stock, Kernel Stock etc). However, it requires some time and effort. [Recommended]
2. Factory Reset may fix your Battery issue (not sure) but it is the quickest method.
3. You could use @Spannaa 's Fastboot images to flash all the images in this thread but via fastboot which is quicker and requires minimal setup. [Recommended]

Hello again,
When you say ''to flash all the images in this thread'' do you mean the 1. OnePlus2 Stock Reset Oxygen OS 3.0.2 and the 2. Qualcomm Drivers Version 1.00.14 ???
Or does it mean that flashing via fastboot the spanna image I am flashing everything at once?

Thank you very much

My Friend, you need to do any one of the above 3 mentioned methods. You could:
1. Follow this guide, the first post which has all the details. This is the method used by OnePlus to restore your phone when you have issues.
3. You could alternatively flash via Fastboot using the images from the mentioned thread.

You chose either one of the above mentioned procedures. Not both. If you run into issues do let is know. The procedure is detailed and if you follow my guide to the dot, you should be all set in the first attempt itself (for Flashing method 1)

I did as told and was able to boot up successfully. But unfortunately the sim and wifi are not getting detected...do you have any solution for this? Also the phone keeps rebooting at random...would be really thankful for a quick solution to this.

 

[qingmui]

Thx!! My OnePlus 2 is almost dead. Fastboot recovery only works for CM recovery, and there is no ROM inside sdcard. I flash TWRP, but no working. ADB sideload, TZ version problem - no luck. Thank you for sharing this thread.

Now is back and alive again

Which version of OnePlus 2 do you have? I have tested this on the European version.

Try this, Re-Flash the whole package AGAIN. After the first boot, reboot into recovery and reset to factory defaults. If it still does not work out, then let me know.

Thank you for the fast response...i have the A2003 that i bought in india...I am still having the same problem...flashed the os again and did a hard reset...but still sim and wifi are not detected.

 

[C.H.T.J.]

Tryed this one but when i upgrade to 3.0.2or clean flash this my camera stays black. Any help for this?

 

[fareed_xtreme]

Even I have an A2003, European version and Indian version are the same. Have you pressed the square button to verify if the Package you have downloaded is in good shape and not corrupted? Do check that.

Alternatively head over to this thread and try flashing through TWRP using the Fastboot package of 3.0.2.

Or you could flash the modem file manually if you know how it's done.

Also as a last resort, try flashing an older version of the stock reset (there will be a version 2.2.0 in the general section or through Fastboot using the thread provided above).

If after all this it still does not work, please open a ticket with OnePlus. Sorry for the inconvenience.

Do follow the above recommendations. However, if it did not work for you with other ROMs, Resets or Fastboot Zips, then I am very sure, none of the above steps will be of much use. Maybe CM might help but again, it's a longshot. Best option for you is to open a Ticket with OnePlus as this looks more inclined towards a driver or hardware issue.

Sorry for the delayed response...i tried the fastboot method as well i have wifi now but no sim yet... i think i found out the problem. The IMEI number seems to be missing... and i read that would be the case for sim not detected.... i tried lots of methods (trying to get into engineering mode & using terminal emulator) to rectify it but was unsuccessful... I think the methods i saw were all for mediatek phones...couldnt find one for qualcomm....do you know any right way for fixing the IMEI issue? Thank you so much for your help so far on this.

I don't have much information on this. If your IMEI doesn't show, it means that one of your device specific partition is corrupted (I guess it's EFS, not sure). If you have a nandroid backup of all your partitions, then you could use them to recover. Else, your options are limited and your only friend is Google search. This doesn't usually happen.

When everything is ok. Press the start button. and let the progress finish.

How much time it can take? Mine is going on for almost two hours now
Only Stop button is clickable and the square button too. Start,Enum, Exit are grayed out.(not clickable)
Btw i did press the stop button after getting frustrated for more than half an hour.
And then again performed integrity check. And then again pressed the start button.
When it finish, does it show some notification?

This could mean that it is still waiting for your device to connect. Have you double checked your drivers and have you found the different line in the flashing app? You will need to restart the process and follow it step by step again.

It will usually take between 8 - 12 minutes max to finish flashing in the app. Also once it's done, in the app all lines will turn green (if I recall correctly).

So i've tried this and various other methods along similar lines. The flashing tool finishes and goes green but then also goes red.
On the reboot, recovery is still missing and i have fastboot.
If i use 'fastboot continue', I boot into the rom for setup and everything starts to work. However, I don't have any recovery, so the phone does not boot. Bootloader is now locked too so I can't try to flash recovery.
