[ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6

[zipalign]

Hey, version 10.3.12 released today, will you make a new fastboot zip? Thanks in advance!

here we are, again.
just like 10.3.11 I simply packed the fastboot .zip but didn't try it on my phone [still quite confortable with my custom ROM going by].
this leads to the usual disclaimer: try it at your own risk, I'll be not responsible for bricked or damaged devices.

just in case anyone would try to DIY, I followed this very guide for all the images I packed.
now, the 10.3.12 fastboot image link follows:

yes sure.
fastboot image will be ready before the weekend.
usual disclaimer: I'll pack it up but do not try it myself, so flash it at your own risk!

Thanks but it didn't work. Is there maybe a different driver that should be tested? I looked at this thread:

https://xdaforums.com/t/urgent-help-with-the-msm-tool-stuck-in-param-preload.3971363/

and they say that with the correct driver the correct device name should show up. Do you have the correct device name showing up? I certainly don't have any device name, I just have "Ports(Com & LPT) -> Qualcomm HS-USB QDLoader 9008 (COM3)"

Ok so I made my phone work finally!!
The driver was fine. I just tried with the link Android 8.1 - OSS 5.1.11 from https://xdaforums.com/t/op6-latest-10-3-8-collection-of-unbrick-tools.3914109/ and it worked first try.

From within Android 8 it does not offer me to upgrade to Android 9 or 10. Is it possible that my OP6 phone is supposed to work with Android 8 only? If so why can I run Android 10 on my other OP6?

For the ones messing up with flashing TWRP (like myself), here are the OS 11.1.1.1 boot.img and Magisk 23 patched boot.imgs.
I got all the other imgs from payload.bin as well, should anyone want to package them (send me a PM and I will share a link).

For Stock:
fastboot flash boot_a oos_11.1.1.1_stock_boot.img
fastboot flash boot_b oos_11.1.1.1_stock_boot.img
fastboot reboot

For root with Magisk 23:
Flash via fastboot:
fastboot flash boot_a magisk_patched-23000_iSZlS.img
fastboot flash boot_b magisk_patched-23000_iSZlS.img
fastboot reboot

But you will lose TWRP then, right?

Yes, absolutely!

I have already lost TWRP and was stuck since I flashed all those non working TWRPs around after updating to OOS 11.1.1.1.

This is just for getting your phone to boot again should you make the same mistake. And you can root, too. Apparently you can then flash TWRP with FKM App, but I haven't tried that yet.

OOS 11.1.1.1 OP6 fastboot link ?
Can you share if you have it?

expect to grab a download link in the next few days

 

[Andy3153]

I can't thank you enough. I just bricked my phone by wiping every section in TWRP, this got it all working again. Thanks man

 

[Andy3153]

Oh yea remember how happy I was in the last comment? Kinda bricked it again
I tried to install this ROM, followed all the steps and anything I would do (try to boot, try to boot to twrp, try to boot to twrp with the img file and fastboot) would give me the qualcomm crashdump. So I tried following these steps again, and now some partitions are apparently locked? The error message is 'FAILED (Remote: Critical Partition not allowed)'

So, yeah, how do I solve this? How do I get the partitions to not be 'critical partitions'? I've tried this:

but it is already unlocked apparently

Oh yea remember how happy I was in the last comment? Kinda bricked it again
I tried to install this ROM, followed all the steps and anything I would do (try to boot, try to boot to twrp, try to boot to twrp with the img file and fastboot) would give me the qualcomm crashdump. So I tried following these steps again, and now some partitions are apparently locked? The error message is 'FAILED (Remote: Critical Partition not allowed)'

Here is what I was doing:

So, yeah, how do I solve this? How do I get the partitions to not be 'critical partitions'? I've tried this:

 √  root@sparkle  >  fastboot flashing unlock                                                     🗁 /home/andy3153/…/10.3.6-OnePlus6Oxygen_22.J.48_OTA_048_all_2010042239_c0c1fee2ee-FASTBOOT/images    🗏 294

but it is already unlocked apparently

Now I am no expert, but reading the first post I believe what you are seeing is normal - those partitions can't be flashed through fastboot. Usually, you will need to boot to TWRP and flash from there.

What exactly did you try to do?
What were your steps?

What were your steps?

So when I unbricked my phone the first time I flashed all the partitions normally, it let me flash them all (that was most likely because all the partitions in TWRP were wiped). But after I tried installing the ROM (which is android 11), I got that qualcomm crashdump for either booting into the normal OS or going into the recovery, but the scariest part is that even if you try to boot TWRP from an image file on your computer using fastboot, I'd still get that crashdump (which just says that it attempted to kill init, which really looks like a kernel panic you'd get on Linux).

I have to note that even when I updated the stock ROM to Android 11 (through the settings app), even then TWRP wouldn't start anymore. To install TWRP back I had to downgrade OOS and then I proceeded to try and install dotOS.

I think there's something about android 11 which just prevents TWRP from starting. And, I think I'd need that sort of full wipe once again, but I can only do it in TWRP, and I can't get into TWRP. So, uh, what's the next thing I could try?

I also have to mention that yes I did use the latest version of TWRP so that isn't a problem

... flashed all the partitions normally, ...

What exactly do you mean by that?

If you flashed all images one by one, then I am not sure why that worked in the first place, as to how I understand the first post, that should not work (the critical ones always have to be flashed by TWRP, no matter if they are wiped or not).

Anyway, like I said, am no expert. What could be the issue is that any of the Android 11 based restore files here have the issue, that TWRP does not work properly. Or at least the specific TWRP packed with the files (if there even is a twrp packed with the files?).

If you want to have TWPR on Android 11, I think you should downgrade again (as that will give you a working TWRP), then root, then either update through system app and then use a TWRP retention script in magisk, or flash the ROM through TWRP - there is a way to keep twrp there I believe, but you would need to find a tutorial (something with rebooting to recovery and flashing again, afaik).

Did you already try to downgrade again with the bat file from Android 10 based ROM (not flashing every img manually?

I tried to install the things in this post, but I'm not on Windows, so I flashed the images manually. It didn't work.

I think there's something in the protected partitions preventing TWRP from booting, I have no idea. But that's where I am at, either trying to write to those protected partitions or finding a 'fastboot update' compatible archive, or getting TWRP to somehow work

It's so annoying that on these new AB phones you don't have the recovery partition. I think that if I could get TWRP somehow onto the device it might work. But it doesn't work with 'fastboot boot', it gives the qualcomm crashdump
