Hard brick for OPT happens when you change critical partitions. It will follow improper firmware flash or accidental erase of certain partitions. The phone won't show any response when hardbricked.
The solution for OPT is similar to OPO - you just need a Qualcomm driver and a recover package. The only full recovery package available is very big and it restore the phone to Hyrdogen OS, with everything wiped. So it would not be very attractive.
Fortunately, thanks to this post from Chinese supporting forum, a minimal version of restore package is provided. It does not wipe user data and guarantee a recovery entry. you would normally be freed using this package. if not, please use the full package in the end of the post
Download link for driver
Download link for Recovery tool
uncompress the files to a local folder.

First step, turn off drive signature enforcement in windows 8/8.1/10. Tutorial Here

Second step, hold the power key for 20 seconds to force turn off power. connect OPT to usb, hold volume+ and power until your PC finds a new hardware (if it doesn't work, try hold volume+ and volume- together)

Third step, go to device manager in your PC, find the new "QUALCOMM-HS USB Diagnostics 9006" device. Update its driver in property page using the Qualcomm driver provided (for 32bit windows, select x86 folder; for 64bit windows, select x64 folder).

Fourth step, when the driver is installed properly, run MSM8994DownloadTool.exe in the recover tools folder, using admin privileges . Clear start in top left corner and wait for it to finish.

Now your OPT should be able to enter TWRP recovery. It still won't boot but you can manually flash anything again (like the full Oxygen OS package).
The procedure is tested by me twice. Enjoy!


p.s: sorry the recovery image in the A2001_save_brick_mini.rar is Chinese. Please download this file, change the name to recovery.img and substitute the file in the recovery tool before flashing.


UPDATE:full Oxygen OS 150805 restoration package for those who experience recovery entry problem. Note that this package wipes everything including internal storage!

Hi,

anyone knows how I can force the OnePlus Two to enter QUALCOMM-HS mode?

I have a "semi-bricked" OP2.

It can boot, but the recovery is broken and I cannot enter it anymore. Worse enough, the bootloader is locked and I cannot unlock it anymore.

So I am kinda stuck and thought this manual would bring me back recovery. But - I cannot get it to enter this specific emergency recovery mode as boot loaders are intact.

Any idea?

Thanks
Andi

Hi,

ok, I am one step further now.

I could bring the device in that mode, flashed via this recovery tool. All partitions were flashed but still no recovery. How can that be? ooops.

I did that many time on my OPO already successfully. But of course with the full recovery package.

So question is, I would not mind starting from scratch... anybody knows where the "big" recovery package that erases everything is available?

Thanks

I'm in a similar situation to you. I lost my recovery and somehow my boot loader is locked again. I can't set OEM unlock as I am on the old version of OxygenOS.

I tried the above instructions but they don't work. The phone reboots as normal, not in to recovery. If you solve this then let me know.

EDIT: I think flashing hydrogenos using this method is the best idea. We can then select the OEM unlock from developer settings, use fastboot to unlock the bootloader and flash a new recovery. The question is how? @qwsdert4

I am on Oxygen 2.0.1 and still do not have the option. Something is really odd...

Hi, I got the "big recovery package" in question from OP support centre in China. It will recover your OPT to factory Hydrogen OS from which you could start over. I'll upload it onto Mega very soon so stay tuned.

Without recovery how do you flash hydrogenOS?

It could be I successfully recoverd following a hint by user @Zyxxeil (many thanks for the help).

If all works I will post soon what I did.

But - have everything running now again. Next I try to flash twrp again and root. If that worked, I will post the steps.

    unbricked !

    Hi all,

    ok, so finally I was able to fully recover my OP2 now.


    Remember, I had the issue described: recovery completely broken, bootloader locked, Enable OEM option in developer options not available.
    So, I was at a dead end. Phone working, but without recovery no chance to take backups, flash something etc.

    So this is what I did now:
    1) Downloaded the USB drivers linked in the OP (or from here:
    https://mega.nz/#!mRgH0KJS!rCo7tgzXLUDQOUxXxtBpwPXk8Bw3JITbozZelmsKEPE )

    2) Used my own, modified recovery tool (which has Hydrogen recovery built in instead of twrp, as twrp continued to be broken). Download my version from here:
    https://mega.nz/#!uBYGHLJD!w-ByaqFeHuUrzJXPuDRXNu4HYcCBKqVAEe7W1xzrY8k

    3) Powered off phone, plugged usb cable into PC

    4) Pressed Vol+ and Power key until I got the mysterios QUALCOMM device as unknown device in windows device manager (just slightly named differently than in the OP)

    5) installed the driver as described in the op

    6) started the recovery tool as decribed in the op (my version) and flashed it

    7) Phone restarted into OOS

    8) I restarted the phone into recovery and voila - HydrogenOS recovery was back

    9) I wiped data and cache in that recovery

    10) I flashed OxygenOS 2.0.0 full version (around 1 GB size)

    11) I flashed without reboot directly after the full version the OTA update of today (40MB size)

    12) Rebooted and I had the "Enable OEM" switch in developer options, which I enabled

    13) Went into fastboot mode and flashed TWRP

    14) ... yes, the rest is as it was before, flashing SuperSu to root the phone etc.

    Finally I am fully functional again. Horray.

    Many thanks to @Zyxxeil who had the idea to try with HydrogenOS recovery instead of TWRP - which helped.

    Hope this is helpful for you guys with the same problem.

    Although I think the full recovery package should help much more easy in future.

    Cheers and have a nice day

    Awesome, I will go ahead and make a full recovery tool that includes these files as well as the latest version of OxygenOS as I did with the Oneplus one.

    @Lord Boeffla
    I found the answer! It is because of new security feature in 5.1.1
    More info- https://nakedsecurity.sophos.com/20...p-5-1-brings-promised-anti-theft-kill-switch/
    So any time when you have pattern or any lock then after a reset the bootloader will be locked! Same is the case if you revert back from CM12.1 to oxygen OS !!
    Happened to me, read here- https://forums.oneplus.net/threads/stuck-in-registration-loop.351187/#post-12816700
    I tried it thrice again to confirm! can you do that too ? :p
    Bootloader gets locked and if you have TWRP recovery installed then there wont be any recovery and you will have to follow this method to get it working! :D
