[OnePlus 6 Guides, News, & Discussion] magnamentis:
then you probably booted from the wrong slot, as mentioned you'd have to go back to the original slot after flashing the twrp zip to the second slot

and be careful not to flash the image to second slot via fastboot but from withing recovery,

why?

because you wouldn't know which is your active slot before booting into twrp, hence it's important to flash the image to "boot boot.img" not to _a and _b.

i'm aware that i forgot to mention that _a _b thing yesterday while i explicitly mentioned the "boot boot.img" command as well as the procedure how to flash to second slot.

i take responsibility for this error because i assumed that it's logical and hence forgot to mention the reason as well as forgot the fact itself vor a split second, sorry for that.

thus far i also admit that the A/B thingy can be tricky untile standard procedures used across the board will be established. i was obviously lucky to get it right on second approach, first one

failed miserably and i considered to send the device back for un-bricking LOL, that was non the 24th of may during very first stages of all this ;)

---------- Post added at 01:01 PM ---------- Previous post was at 12:54 PM ----------

just about the restore:

one has to delete all the 999 folders in their appropriate directories ( misc, system, user etc) to restore.

999 folders are parallel apps related, no clue how this is coded so that twrp would produce an error but however, restoring works for me if i delete those folders and skip images (system image partition and vendor image partition)

i certainly know that surprisingly even clean slates can behave differently at times, no clue why this is but i can only repeat that my recovery works like any other ever did on any of my various devices.

i'm willing to accept that i was just lucky while i had big issues with first variant, perhaps the reward for hard work to get back on track LOL

agree about sticking to OOS for now, not even difficult at it's current performance ;) LOS will take a month approx (from past experience) and those based on LOS another month or so, true that as well

cheers

No, this is the next one I´m going to try. I´m short on time now, but also in "try and error" - mood. I´d like to try restoring a backup via twrp, and I hope this is the one which it could work with. Has anyone already tried or will I be the first one..?
[OnePlus 6 Guides, News, & Discussion] magnamentis:
if your wifi is broken boot from the other slot and report back, if i boot from other slot my wifi ges too but not on current
[OnePlus 6 Guides, News, & Discussion] Flying Fox:
It happened yesterday. And I tried to boot from both slots... I tried other different ways as well. Not a big deal, but I couldn´t make wifi working again. I´m sure it was me doing something wrong. Now everything is working fine, but with the olderst version of twrp posted here at the beginning. Now I am currently testing another one.... ;)

By the way, does system backup/restore work with this version?
[OnePlus 6 Guides, News, & Discussion] magnamentis:
good to know that all works now, interestingly i had issue with exactly that varian, hence as mentioned earlier, sometimes things appear to be a bit weird and hard to explain, ultimately we all gonna manage and learned a lot in the process.

sooner or later there will be a multitude of post with more insight into the A/B topic. for now it's quite new, perhaps i go and read a bit in google official pixel sites, i assume that's where we currently can find best up to date info on A/B as well as treble.

after all XDA is and remains a learning/developer site and as we can see here it won't change so soon ;)

cheers :highfive:

I actually never had to install any OnePlus drivers on Windows 10, just using a simple and/fastboot package, same for my old op3. Everything's just working after plugging in. I guess those drivers are for older os?
[OnePlus 6 Guides, News, & Discussion] loike:
Just a quick question. Is it possible to flash this kernel without flashing twrp? If I boot to twrp recovery (fastboot boot twrp.img) and make a backup of the original boot and flash this kernel will I have any problems? Bootloader is already unlocked btw.

Thanks for any advice.
[OnePlus 6 Guides, News, & Discussion] magnamentis:
which kernel? this is not a dedicated kernel thread hence if you don't quote or mention readers have no clue which kernel you mean.

then it sound very contradictory to ask whether a kernel can be installed without twrp and then talking about making a backup of boot

from that twrp that one does apparently not want to install.

structure your posts and provide the minimum of necessary and comprehensive information, else you make others think too long to no avail, in other words, steal our time ;)

Followed instructions perfectly and my device wouldn't boot into OS......anyway I'm just restoring to stock and will go the Magisk only route until TWRP is more of a stable release.
[OnePlus 6 Guides, News, & Discussion] magnamentis:
99% of alll people who claim to have followed procedures to the T made an user error.

user errors come with the caveat that one is not aware of the mistake, else would not have done it.

to not admit that in close to 100% it's user error is the greates handicap upon troubleshooting.

best practice is to go from scratch and repeat the procedure that is known to work for the vast majority.

not only can errors be made during the process, there are as well things that are different as a starting point. only way to know for sure is to go from clean slate and thing is that it then it usually works as expected.

don't underestimate residues. deleting a file does not get rid of it, it's just the "link" that makes the data visible that is broken so that the space can be used for something new but at times things can stay in memory for a long long time.

cleanest possible slate you will get two ways:

cleanest does not exclude other methods but indicates safest method to reach the intended state:

a) lock and re-unlock the bootloader. the device will boot into system ( setup wizzard )

b) format into another file system, i.e. ext2, and back to ext4, there will be no residues but be careful with which partition to do that, i recommend only system and data, but under no circumstances system image partition and better not vendor image partition and obviously you won't want to format your EFS partition LOL

so safe and targetleading is to lock & re-unlock the bootloader because that process is given and will damage nothing but you gonna loose all your data.

further whenver fiddling with recoveries etc. better keep your device on swipe or none security. at times you'd need a password/phrase and i've seen people forgetting that ;)

Hi!

I'm currently stuck on the TEAMWIN loading screen after flashing TWRP to my phone. I've left it there for over 20 minutes, and nothing seems to be happening.

My phone was bought in china, and came with Hydrogen OS - (i'm trying to put oxygen on this bad boy)

Looking back at the procedure, the only thing i can think of that i may not have done correctly, is that i did not update the phone OS. I just took it out of the box, and didn't bother connecting to wifi.

Have I screwed things up beyond repair? I can't seem to get back to the OS. Only to fastboot.

Help would be greatly appreciated! <3

Would it make sense for me to unlock the bootloader as soon as I get the phone so I won't have to wipe data later, and then install TWRP and Magisk later when they are official and more stable?
[OnePlus 6 Guides, News, & Discussion] KnifeFed:
Yup, that's what I did. Unless you really need for Google Play Store to list your device as "Certified" so you can install e.g. Netflix. That won't work with an unlocked bootloader but works fine once you flash Magisk.

I would like to report an issue I had today following the instructions from OP on how to flash TWRP recovery.

After updating and running on OxygenOS 5.1.6, after following the instructions on thread #5 at the link: https://xdaforums.com/showpost.php?p=76635744&postcount=148, when booting back into the OS after completing all steps successfully, wi-fi doesn't work at all.

I tried 2-3 times doing all the steps from start to finish, only to end always with the same result.

As written in the post, the steps I did are:

1. fastboot flash boot_a twrp.img

2. fastboot flash boot_b twrp.img

3. booted into recovery from bootloader

4. flashed boot.img

5. flashed the TWRP Fix (TWRPWorkingInstaller)

6. flashed root zip

7. rebooted from TWRP into recovery again to verify that TWRP is still present.

8. after all is good, booted back into the OS

9. no wi-fi

If anybody encounters the issue, following the instructions in the following link will restore your OnePlus 6 back to stock:

https://xdaforums.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665

2.apply a local update from setting menu

3.reboot to fastboot and flash offical twrp

4.reboot to twrp flash magisk and syetemless xposed ( swith to slot_b and flash them again )

According to flar2 this is a warning which newer devices show when flashed custom kernel. I got this warning too, but everything works like a charm. So if you don't restart your phone frequently, you will not see that message quite often on the other hand you can safely ignore it.
[OnePlus 6 Guides, News, & Discussion] iElvis:
As stated above, this is nothing but a system message saying "You have a custom kernel." It has no effect on anything and can be ignored.

Can I just update OTA to Oxygen 5.1.6?
[OnePlus 6 Guides, News, & Discussion] Kiruasan:
You can install TWRP and then go with installing the update for that you can do this :

- download the update and put it in an accessible path

- install TWRP following the official site process

- boot on TWRP and update oos

- before rebooting reflash the TWRP zip so you don't loose recovery

- you should restart on recovery ( make sure you have changed slot ...) To flash magisk again BUT I AM NOT SURE ABOUT THIS STEP ...( i juste restarted to system and then recovery to reinstall magisk ...)

I guess you can just update and install TWRP and magisk after finishing the update for the other method ...maybe more easier ( at least to write ;))

[OnePlus 6 Guides, News, & Discussion] iElvis:
Not at the moment, and that's unlikely to change. Part of widevine, as I understand it, is baked into the hardware. To get L1 certification, all content processing, decryption, and control has to take place inside the processor's trusted execution environment. Unlocking your bootloader breaks enough of the TEE to prevent L1.

[OnePlus 6 Guides, News, & Discussion] den_zel:
Thank you very much, it worked pretty easy:

1. I downloaded the update, Oxygen realized that the phone is rooted, so it downloaded and installed the whole OS not just the OTA-Update.

2. BEFORE restart in Magisk I chose to install and then chose to second partition (the option sais after OTA).

3. After restart Oxygen is updated and I still have root. Only TWRP I would have to reinstall, but I don't need it at the moment, so everything is fine ;)

No. If you already have TWRP, you can flash everything (OTA/TWRP/Magisk zips) in TWRP. One after another without rebooting.

If you reboot too soon (as happens when you flash OTA in the Settings itself) then you lose TWRP.

So I would follow the official TWRP installation. One tutorial you can find here. But I didn't try that as I don't need TWRP at the moment, so better do your research :)
