How to Unroot OnePlus 6 in Bootloop/Hard-Brick!


Originally published at:

There are times where your rooted OnePlus 6 may be in a permanent bootloop situation. No matter what you do, including trying to unroot using TWRP or even trying the fastboot unroot method, it may still be in a bootloop or in other words, “hard brick”. Before crying on your mom’s shoulder or your wife’s…

Flash chinese OnePlus 6

Max, I’m having an issue when I use the MSM tool. It connects fine and gets close to finishing, but then the phone always disconnects after around 200 seconds and gives “FirehoseCheckRSP Failed, Errno: 258”. Phone is hard bricked and I don’t see any other option.


Did you try another computer?


Yup! That’s exactly what fixed my problem. Thanks for the advice though, appreciate the reply. I’m just really happy I no longer have a brick!


I cant flash Oxygen os via the update menu on the op6. So i open the bootloader, installed twrp and flash Oxygen via twrp. Today i want to calibrate my Battery so i discharge it to zero. I pluged my charger in but it wont show the bettery symbol. it just show the “Your boorloader is unlocked” Screen and freeze there. I can start my phone with the power button. But i want to charge it when its turned off.


It should charge regardless are you using OnePlus original charger?


i fixed it.
I had Lineageos installed before. And then wanted to go back to Stockrom. I solved my problem by simply flashing the stockrom again on partition A instead of partition b only. And booted the phone from partition A.


Yeah i use an original Charger


Ty for ur reply :). Did u have any tip to get the best battery life on the oneplus ? It seems like OOS have the best batterylife. I flashed Pixelexperience and LineageOS last weeks on my OP. My Battery life didnt get better after i flashed thoose roms. I mean 6hours screen on isnt that Bad but it was alot better at the beginning. Did u have a good rom + a good kernel combination ?


I will have to get back to u on this, stay tuned plz.


damn i got linux but im not even sure if this is the right download for my situation. long story short i turn on my phone and it get stuck o" n the "bootloader is unlocked and software integrity blah blah blah like usual but its stuck there. when i fastboot to flash lock it and start again it says “Your device is corrupt. It cant be trusted and will not boot” I assume this is download should work but if not anyone kind enough to point me in the right direction would be freakin awsome.


Just borrow your friend’s Win computer for a day. This is easy to do.


I followed your video and it worked fine on a windows 10 laptop. Thanks. I was wondering because my laptop is currently dual booting win 7 and Linux mint will the msm tool still work. From taking a look at it it basically acts the same way it does when I try to run it on wine. Any advice?


My qualcomm cable doesn’t show up under ports in device manager but it recognizes that my phone is connected. When I try to start the MSM tool it just says “waiting for device” and can’t download anything.


Hit download and it says waiting for device, connect the phone and cable. Hold vol up and power until download starts. Should work that way.


Does this tool work it is in a boot loop with no recovery and the device state is locked?
