So. I was on Lineage. I've unlocked my bootloader and all was good, but I was not happy with certain things in Lineage. I decided I would flash the AOSP provided by AlaskaLinuxUser.
I have used it before, and it was working before in the past.
This time, I got a black screen where the volume slider and power menu appear but there is no other functionality and then the device eventually reboots.
So I went back to Lineage, this time Lineage stays on an infinite boot logo, never actually booting or restarting.
I have cleared dalv and user data both times.
So I used NewFlasher to go back to stock and try again, seeing as stock boots just fine.
Same thing, AOSP black screen with vol/power menu; and Lineage stuck on boot logo.
Am I missing something this time around?!
Did you flash both boot slots? Which is like a requirement when going to lineage 10. Especially when ur coming from aosp. The commands are in the second post of the Lin 17 post

I thought about this, newer kernel, newer fastboot, so it used to look for Slot__A / Slot__B, now it looks for Slot_A / Slot_B instead. Cmd line has trouble flashing AOSP to boot_a/b or system_a/b, So I used TWRP instead and flashed Lineage twice as a test (once to A, then again on B), still got a black screen. Same with AOSP, flashed to A, then used fastboot boot TWRP to temp boot TWRP and switch to B; then flash AOSP on B, still black screen their too; both then reboot after a few minutes and get stuck on the boot.
Odd as this may sound, it has worked fine so far before without flashing both boot slots.
EDIT: To clarify, I was going from Lineage to AOSP when this all started. Now no custom ROM's will work properly.

I got my OnePlus 7 Pro today and tried to install Magisk by patching the boot.img. After trying to flash the patched image, I now have an issue where rebooting the devices leads me straight back to the bootloader. Trying to enter recovery also leads me straight back to the bootloader. I tried flashing the original boot.img I extracted from the OTA update file provided by OnePlus, but it still isn't working. I do not have TWRP or any custom recovery installed. Any help would be much appreciated. I noticed similar threads, however they all installed twrp, though I haven't yet as trying to run "fastboot boot twrp.img" always resulted in it booting to a screen saying "fastboot mode" which wasn't terribly helpful.
Edit: Its not the tmobile/5g/carrier version. I purchased it through OnePlus' website though I forget the exact model number.
Well, "fastboot boot twrp.img" does not work on all devices, sometimes you have to use: fastboot flash boot insert_twrp_img_name_here.imgLearned that the hard way, also use the unofficial twrp from mauronofrio.
Had the same problem as you have, and fixed it with that unofficial twrp.

Did you need to completely revert to stock after the issue, or did flashing twrp fix the fastboot loop?
Edit: Trying to flash the stock fastboot rom currently as flashing twrp did nothing probably because me trying to fix it broke everything. Hopefully the stock rom will get everything back to a working state where I can try again, just this time flashing twrp.
Also using windows this time instead of linux....

Ok, so, trying to restore stock seems to have failed miserably.... any advice is most welcomed qq
OK.... so trying to unbrick the device using the msm stuff, I couldn't even make it to the downloader screen. After holding volume +/- and powering off, my screen is now black HOWEVER the phone gets detected by windows when I plug & unplug it. I have no idea what to do anymore. Someone please help
Figured I'd give the solution here in case someone else is in the same exact problem as me:
Follow the instructions over at https://forum.xda-developers.com/oneplus-7-pro/how-to/op7pro-collection-unbrick-tools-t3956595
I tried to de-brick it using the fastboot roms and all that, no dice. The only thing that seems to have worked was following the above and using the msm tool. Everything wiped, but hey, at least the phone is bootable again and now I have a way to fix it should this happen again. Yay for happy endings.
Edit: Also, following Faith1105's advice, flashing twrp to boot instead of trying to just boot it first worked successfully and from there I was able to install magisk.
Edit 2: Now wifi isn't working.... why life, why...
Edit 3: OK: EVERYTHING IS GOOD NOW. Twrp ran into a boot loop issue, used twrp to flash the most recent android 10 zip, rebooted and was greeted by stock recovery, then used that to wipe absolutely everything and reboot. After skipping through initial setup and making use wifi was working I rebooted again and this time tried booting twrp the way the usual instructions say to, this time it worked for whatever reason so once that started I used twrp to flash twrp's installer and magisk. It looks like everything is working correctly now. If you have the same issue maybe this stuff will work for you or maybe not: I don't know, and honestly I'm now brain dead lol.
Hi, as the title explains I can flash and boot into lineage os but when I try to flash a stock OxygenOS signed flashable zip from this thread (https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244)
and when I boot to system, the screen doesn't show a boot logo, it just goes black for a few seconds before rebooting back to twrp (also if it helps, when it goes to twrp all the files are gibberish, I have to shut off the phone and boot into it from fastboot or I can't see any files).
This all started because I misunderstood the instructions and tried to flash an ota package which then broke the system, it's working now but I'd much rather use OOS as Lineage is missing a lot of the features I'm used to on Oxygen.
I've also tried the "flash-all-partitins-fastboot" from https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665 but unfortunately that gave the same issue, it just went back to recovery and wouldn't load OOS.
If anyone has any ideas on how to get back to oxygen that'd be super helpful! I'm considering using the MSM tool but I'd rather not have to start from scratch and lose all my files.
I'm just guessing, but there might be something wrong with your TWRP, did you try re-flashing it?

I should've clarified in the post, I mean all the files are gibberish (as in not decrypted I think?) but when I
Code:
fastboot boot twrp.img
it works fine and I can see all the files.
I've probably tried flashing it 4 times through twrp but every time it just does the same thing, boot to system just shows a black screen for a few seconds then reboots to twrp.
I'd love to use blu_spark like everyone recommends but I can't find the blu_spark recovery for the op6, only their kernel.
The reason why it's gibberish is because your device is encrypted and you need to input the password in the twrp to be able to access it. Seems the twrp doesn't detect the encryption correctly so there might be something wrong with it.
Here is the bluespark twrp https://github.com/engstk/android_device_oneplus_enchilada/releases

I just tried with blu_spark and the same thing happens but I realised something else, twrp only doesn't work on slot A.
If I see that it didn't decrypt the files, I can set B to active, reboot to recovery, and it works perfectly.
I noticed after one of the failed boots it switched the active slot to B even though I had set it to A before flashing. So every time it doesn't show the logo or anything, it sets the active slot from A to B and reboots to recovery.
Also I just looked and from the Backup page, it shows 2.7 GB for system on slot A and 1.7GB on slot B so I'm going to try wiping both and reflashing the flashable signed zip on each then twrp.
UPDATE: Just did that and the twrp installer was giving an error saying unsupported android version so I looked and system is only 4MB after flashing that package (OnePlus6Oxgygen_22_OTA_034_all_...zip), I'm trying an older one (...OTA_026...zip) to see if that actually works.
So I tried with the older one and lineage and they both still left the system partition at 4MB and the blu_spark twrp installer isn't detecting an android version. The system image partition is at 2.6GB if that means anything.
Oh wait more update, I'm dumb and shut off the phone while taking the case off (got stuck and it was pushing the power button) and even though the twrp installer couldn't detect anything and twrp said No OS installed when trying to boot to system, lineage just started up, no problem. I am very confused I miss when there was one system partition.
How are you flashing the OS?

I'm using twrp, blu_spark and normal, and both have the same result. They can flash lineage and it runs fine, but oxygen refuses to boot and just switches the active slot and goes to recovery instead.
I also tried the fastboot rom flashing thing from the thread I linked to in the OP and it's the same thing, just goes back to recovery and wont boot.
P.S. I'm currently copying over /sdcard to an external drive and if I can't figure out how to fix this by the time that's done, I'll just use MsmDownloadTool and start over.
And you are wiping each time before flashing it, right? If it is the case then the download tool is probably the easiest way to go about it, rather than spending days troubleshooting it.

I've tried it with and without wiping and it always seems to do the same thing either way, works with LOS not with OOS. Thanks for the help! but yeah I think I'm just going to end up using the download tool once everything's over.
I got my phone yesterday, and I can't flash custom roms. My phone gets stuck on the boot screen (the animation is working as expected) for over thirty minutes, then I give up. I am/was rooted on the latest stock image. In the Download folder, I put the ROM (I have tried with crDroid and Bliss), twrp.zip, nano gapps, and Magisk. I flash the ROM and TWRP and reboot into recovery. Whenever I do this, I no longer have a Downloads folder or files. So, not knowing what to do, I sideload gapps and Magisk and reboot system. Then, I inevitably get stuck on the boot screen animation. What am I doing wrong?
Hello have you try to format data before or after flash custom rom? Some rom don’t work if not do.
Are you familiar with A/B slot partitions and their related behaviors? It's markedly different from single slot systems.

I am not familiar with A/B slot partitions. I followed a guide step-by-step, so I wasn't too concerned about my ignorance. Should I be doing something special? Thanks.

Yes. A lot. Get very familiar with how A/B slots work. It changes many things about the whole flashing process. Trying to do things the same way as before leads to exactly what you're experiencing.

Same thing happened to me, I had to forced the phone off (Volume + and Power) without plug-in the USB after is off I went into EDL mode (Volume +- together and Power) then immediately plug in to your ready PC with msm already ready to go.
You might have to try it a few times...
That's what I did a while back.
Hi,
I am struggling with my new Nord (AC2003), basically I have OEM unlocked fine, I have managed to boot TWRP etc... without issues and I can flash the phone this also works. I have tried the Lineage OS install flashing the IMG files, that left the biggest mess! TWRP couldn't even read my system partition anymore so I had to restore via EDL, I then tried PixysOS-v4.0.3 followed the instructions to the letter twice through, both times same result the phone boots straight to fastboot screen! If I hit start or tell it to boot normally it just does it again,
I have been on Samsung for a few years and to be honest haven't flashed an Android phone for about 4 years now but prior to that I was flashing custom ROMS nearly every day, so am no stranger to these processes albeit just a little rusty.
Anybody got any ideas what I could be doing wrong? Getting bored of going through system setup over and over again! All I want is a custom ROM with no Gapps in it
Thanks
CLEAN install from latest factory, locked and everything, latest lineage nightly.
I installed lineage and then rebooted recovery and installed addons like the guide says.
But every time I restart it's a 50/50 flip if it will try to boot slot a or b, and b won't boot, just lineage logo forever, I have to ADB change it or just restart the phone enough times to fix it.
Pulling my hair out trying to fix this for months.
ANYONE please?
Thank you.
Correct me if I'm wrong, but I think when there's a failed boot, it will fall-back onto the other boot slot.

Did you flash boot.img twice ("fastboot flash boot_A" AND "fastboot flash boot_B")?
