General PSA: DO NOT use the DSU Loader on the N200 - you will BRICK

[lzgmc]

There have been multiple reports of people bricking their devices after flashing a GSI with the DSU Loader found in Developer Options. In fact, I was probably the first guy to brick my N200 by installing a DSU to it. After installing a DSU and rebooting, the phone will attempt to boot the GSI and then show a Qualcomm CrashDump screen. After forcing the device to reboot, the phone will show a screen that says "Your device is corrupt" and will no longer boot. Although it is possible to boot into Fastboot mode, the phone will refuse to boot to recovery, and many Fastboot commands do not work since the bootloader is locked. Since there are no MSM tools available yet and the remote service team at OP support doesn't have the ROM files for this phone, your only option at this point would be to request a repair from OnePlus under warranty.

While it may be possible to use the DSU Loader on the N200 without bricking after unlocking the bootloader as shown in this thread, I still would recommend against it until unbrick tools are released.

Yes, if you attempt to use the DSU loader without unlocking the bootloader first, it appears it will fail verified boot since the GSI image is not signed on OnePlus.

Can you still boot into fastboot mode (hold vol down while booting)? You can try switching the active slot to a or b and see if it will boot that way.

fastboot --set-active=b

Also, if you can boot into recovery, try the "Erase everything" option.

You can still boot into fastboot by holding the volume up+down buttons while booting. However the bootloader won't let you switch the active slot if the bootloader is locked.

Even if you select Recovery mode in fastboot mode, the phone will still display the device is corrupt error and refuse to boot into recovery.

While I'm guilty of Bricking my phone by doing exactly what you describe .. there's a little confusion on ... t-mobile locked phones and the ones bought unlocked from 1+ or Amazon....any difference in how to fix those 2.. I'm on a phone bought directly from 1+

I'll answer my own question .. it don't matter .. I also tried switching from b to a but it won't allow it as it is locked

Did you by any chance enable OEM unlock in the developer setting before it bricked? If you haven't tried already, what happens when you try to unlock the bootloader in fastboot?

Won't allow it because it's locked .. so you can't unlock the bootloader. Hopefully oneplus will release the rom soon or there's a work around this

No I did not unlock the oem in developer before all this

 

[TheLoonyRebel]

DSU runs fine once you are bootloader unlocked. I can confirm this myself.

 

[mingkee]

There's a common sense
Flashing anything modified, even from stock, requires unlocked bootloader
BTW, I have mine rooted with patched kernel after bootloader unlocked

This thread is a whole 1 day old, so don't feel bad about missing it weeks ago.

I believe there's a stock ROM here:

Rooting Stock Firmware W/ Magisk

Once you have your bootloader unlocked (See edale1's post), you can get started! Disclaimer: * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...)...

But I also believe you need your bootloader to already be unlocked to actually fix it. Not sure though.

at this point the rom wont be enough huh! .. the downlooad tool is also a must to fix the lock on the bootloader ...
i guess its worth saying this is for the fully paid one from the oneplus website here in US

Have the T-Mobile or Metro variant? See this thread:

Have the unlocked variant? You're screwed. Contact OnePlus for a repair.

If you have a spare phone lying around, try flashing a GSI to see what custom ROM developers are up to these days. Since installing a GSI only requires Even with installing TWRP recovery, it only worked after I had successfully installed magisk on the device by flashing the magisk patched boot.

I just wanted to let you all know. If this happens to you, you CAN use the MSM recovery tool. I found the T-Mobile variants' EDL firmware in the OnePlus community repositories. Let me know if you need them, as I will upload them to a thread with a step by step recovery guide if needed. I had bricked my device by trying the GSI image through DSU Loader, but was successfully able to recover the device with the MSM tool
