Unable to root 6T, gets stuck on Fastboot Mode Flash screen or Bootloader message
ROOTING (+/- TWRP)
Magisk zip is to be
found here
TWRP latest .img and installer
are to be found here
Don’t use all-in-one tools, you’re a grown up person you can to it by yourself. Yes you can.
If you're not rooted and run an OOS version older than 10.3.1, update your phone normally to latest OOS stable version then do as below
If you’re not rooted and running 10.3.1 or higher, those are the simplest steps to gain root.
Unlock your bootloader (will wipe everything…): “fastboot oem unlock” from a computer (see beginning of OP to know why I don’t detail this) with phone in fastboot mode
Grab latest Magisk zip on your phone and latest TWRP .img on your computer (AND TWRP installer .zip on your phone if you want to install TWRP permanently). Boot in fastboot mode your phone.
Then :
- “fastboot boot twrp_latest.img” (adapt to the name and path of your twrp file)
- within TWRP, flash TWRP installer .zip if you want to keep TWRP
- flash Magisk zip (always AFTER flashing TWRP)
Reboot
(you can theoretically use the TWRP feature ‘install recovery ramdisk’ to avoid flashing twrp installer but never tested)
Note: please STOP using blue_spark TWRP!!! Support for OP6T has been stopped long time ago, only OP6 twrp is still actively supported by eng.stk (errors are mandatory if you flash it on 6t). I even see people that use a 3.2.x version of blue_spark...
Hi, I bought a refurbished OnePlus 6T the other day and I am unable to root it. If I detail where I am I hope you can help me:
Installed all OnePlus USB drivers
Installed new Fastboot and ADB drivers
Setup phone
I run all system updates to get me to OOS 10.3.3
I enable dev mode
Enter developer options
Enable OEM unlock
Enable USB Debugging
Enable Advanced Reboot
Reboot into Bootloader
Using adb:
Confirm it sees my device with fastboot devices
Yes
Unlock OEM with fastboot oem unlock
Enable bootloader
Reboot phone
Run setup again
Enable USB debugging again
Up until here things go fine
Reboot into bootloader
Confirm it sees my device with fastboot devices
Yes
Run fastboot boot twrp-3.3.1-1-fajita.img (twrp-3.3.1-1-fajita.img being the latest TWRP I can see for the fajita build)
Nothing
Phone sits on Fastboot Mode flashscreen and does nothing
If I long power off and restart the device I get stuck on the bootloader warning screen as above and the phone just hangs and hangs
Cannot boot into TWRP as flashing the img seems to brick the phone
Unable to access recovery to flash TWRP or Magisk (both zips on the phone)
I then have to run the MSM Download tool to reset the phone and start all over again.
I can't see I am doing anything wrong (still, I am no expert and have to always follow guides) and have done this 4 or 5 times now
Looking at the info above I ran the getvar command and my phone comes back as using current-slot a
PS C:\adb> fastboot getvar current-slot
current-slot: a
Finished. Total time: 0.003s
PS C:\adb>
Do I need to run fastboot flash boot_a twrp-3.3.1-1-fajita.img to ensure the img is being flashed to the correct slot?
I really want to use the phone but want to get onto LineageOS before I do as I don't want any Google crap on there at all where it can be avoided.
I hope this gives you enough info to help - I am really stuck at the moment!
Thanks
Simon
