If you came from Audax. You need to do a format data.

That what i did :

- save all wat you want on your PC

- flash OB10

- setup the rom

- flash blu saprk with treble support

- flash this rom without magisk

- setup the rom

- flash blu saprk with treble support

- flash magisk

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Vincent_40:
After setup of Ob10 tap to update button to install Ob11 and 12 with stock recovery to create vendor partition.

Ok guys I need some help. I was on OB12 stock with magisk. Now I tried to flash this rom and got stuck on blank screen with LED light ON in light blue color. I don't understand what I did wrong. I simply rebooted to blu-spark and didn't wipe anything, just flashed aroma without root, since root is already present. I am encrypted. What should I do? Thanks.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Bradl79:
If u install the OS u still have to install root. go back to twrp and install root and reboot, if that does not work redo but this time still install root, if u lost twrp just reflash via fastboot. Do not wipe anything
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] GUGUITOMTG4:
That sounds like a good solution, but even OTAs are failing to install. flashed stock recovery, Downloaded the full zip via system update, but when it rebooted it failed while starting the installation in stock recovery. kind of puzzled here after 7 years flashing Roms
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Vincent_40:
Try to flash manualy OB11 & 12 with stock revovery. No need to flash blu spark untill Ob12 is not installed.

It's weird because it worked fine for me
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] GUGUITOMTG4:
Fails to install as well. Also tried manual flashing OTA and failed. I suspect magisk is doing something weird here. It wont boot on ob10 while unrooted. Must be rooted with magiskand it boots. Once it boots, I check for update, It warns about phone being rooted and suggest to download the full zip. once download is done I get into the same 'failed' process again.

that is correct, keep in mind this rom is still stock OxygenOS even installing a full zip if u do not install magisk OxygenOS will reinstall stock recovery. U can just reflash it via fastboot

I flashed this with the option checked to install Magisk. I booted me back into TWRP. Is this the bootloop you were speaking of? I had previously uninstalled all Magisk modules but do I still need to at this point flash the Magisk uninstall zip in TWRP? If so, once we type the terminal code, what do we do next? Thank you! Your work is appreciated!

to go from OB12 to 5.1.4 u will have to do a clean flash, u will install just the OS with no mods or root, let boot to OS, u will have to reflash TWRP via fastboot. If you are decyrpted u will click the Force Encryption Disabler (not tested though) (if you are staying on OxygenOS it is better to just stay encrypted, decryption is mainly for Custom Roms outside of OxygenOS, there is really no benefit if you are on OxygenOS but that is just my opinion.)

When u have TWRP installed then u can install OS, Mods and Root (I use Magisk 16.0 due to I had issues booting with 16.7 on a clean install) This will help too if you are getting booted back into TWRP.

I've finally installed your rom. I had some problems. Instead of starting from op10 I had to install op13. I had to repeat the installation of your rom 3 times cause every time looked like nothing was happening. The aroma was succcesfull but after the reboot lolled like nothing happened. The rom was still the op13 pure. I installed without magisk. Anyway where is the advanced reboot menu?

OnePlus Contacts is a debloat option in Aroma. You can install OnePlus Contacts or a magisk module with Google contacts.

Hello!

I don't know what I could be doing wrong.

I'm in latest oficial stock build (ONEPLUS A5010_43_180718), Oxygen version 5.1.4. Using TWRP blu_spark 8.81, following the indicated steps to install.

The ROM will not pass from the booting animation, it remains there forever. I have to perform a cold reboot.

Tried to install ROM by checking "disable force encryption", but no results. Tried again but not selecting that option, still no results. Tried choosing magisk, not choosing magisk, choosing supersu, not choosing supersu, not choosing any rooting method at all... Nothing.

Had to restore to my latest backup.

Any ideas or suggestions would be appreciated. Thank you in advance.

Did the notification shade “Do not disturb” icon and “Automatic rules” disappeared in beta 13?

I just moved to the open beta from another ROM. In the process I had beta 12.2 for about a day. In that version I had the DND icon in the notification shade and I had an automatic night rule.

After upgrading to beta 13 these options disappeared for me.

Was this taken from beta 13?

Debloating

What is the correct debloat method?

The reason I ask is that the contacts app keeps force closing or getting stuck at 78% restore from backup vcf file. I do not use any Google accounts as I install MicroG.

This is how I debloat,

1-Select debloat all Google & Oneplus apps,

2-Then the rest on the list except for the ones with warnings.

I did manage to get the ROM to work once but went back to custom ROM to try something out. But returned to this ROM it's the smoothest & most responsive.

Am I doing anything wrong?

No u do not have to go through all of that if u are dirty flashing, If you already on OB13 u can just flash OB14 and just go through the your aroma options. U will need to choose root (to avoid in having to reflash twrp) and do no wipe anything. Also to remember if you are decrytped to choose Force encryption disabler

V7.0 test confirmed

Just went back stock OOS5.1.4 and OTA to 5.1.5 stock,

after that, reflash blu_spark twrp v8.8.3 from fastboot, and go through wipe /system, /cache,

install theOne5TOS v7.0(magisk 16.7) and blu_spark r128_treble kernel, and reboot,

so far, old data remains, and everything good.

Keep in mand, I did made backup before every trial, so in worst case, it doesn't make me feel bad even failure :D

No luck from v6.1 OOS5.1.4 to 5.1.5, vendor partition not exist.

even flashing stock 5.1.5 full zip facing vendor partition error.(blu_spark 8.8.3 twrp trebled)

I tried to clean install 5.1.5 (with erasing user data in bootloader), but everytime I have e2001 : failed to update vendor image. I've tested with latest codeworks and bluspark TWRP.

Any idea ?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Sam Nakamura:
Flash maybe 5.1.4 before flashing 5.1.5, the implementation of "project treble" has been done in 2 steps by OnePlus, where 5.1.4 created /vendor and 5.1.5 filled it. So you can't leave out one of those to have treble working properly. The error you posted implies a issue with the treble implementation, specifically the vendor partition. That's why I'd try to flash both of the mentioned builds to see if it fixes the problem...
