Their SoC are same (both SD855 & SD855+ are SM8150), the only diff is SDX55 or SDX50 external modem

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] -=Guybrush=-:
The best advice I can give you is:

Put your Guacamole in EDL mode (just keep volume up and down pressed together while plugging in the USB cable, very simple)

Install the appropriate drivers you can find here for example (please note that sometimes it is necessary to disable driver signing and/or force Windows to pick up the driver in spite of the fact it complains it isn't the right one; I don't know if it is the case for the drivers downloadable there as I've installed the EDL driver on my Windows setup years ago and I don't remember the source nor what it was needed to do back then but certainly nothing different than what I've told you). If you manage to install the EDL driver successfully, then after connecting your Guacamole (in EDL mode, that's clear) to your Windows PC you would get a new device under the Ports category inside device management (to open it, just WIN+R then devmgmt.msc)

Use the appropriate package you can find in this thread or, if you prefer, just download it from here (please pay attention to downloading the right package for your version)

I know the latest packages available there are on Q but downgrading is not an issue. I can give it for granted because it's what I've already done to repeatedly and successfully revive my Guacamoleg (the only package available in that repository for it is on Pie while I was always coming from Q, no issues at all).

After restoring a working OOS version, you could just download the latest FULL OTA (ABSOLUTELY not a patch) from this Telegram group and apply it. You would be on the latest OOS 11 in what I believe to be the cleanest approach.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] -=Guybrush=-:
My mistake then, I apologize. I still have a doubt though: if I read the specs for Guacamoleg, I get SD 855 everywhere so I tend to believe the external modem isn't the one used by the SD 855+ and I would go in crashdump mode anyway.

I would try (I've already tried some other approaches and I've always been able to restore my Guacamoleg to working OOS by EDL so no great fears about that) but at this point why not a custom rom for Hotdog instead of OOS 11? Do I still miss something? Thanks for your advices. :)
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] -=Guybrush=-:
No, root isn't absolutely needed. Just unlocked bootloader. I see that many have linked directly downloadable boot.img files but, given that new updates are coming out regularly, I think (so just my one cent opinion) the best is always extracting the current boot.img from the just downloaded rom to avoid issues.

My guide has taken quite a lot to be written but it takes less than five minutes to be followed and much of it needs to be done only once to get a working environment but, after then, extracting boot.img is just a matter of seconds.

Also, Payload Dumper is installable even under Windows and Linux (with Python installed in both cases, that's clear) and I've no issues with extending my guide to those scenarios too. I've choosen Termux under Android just because it is an approach with a smaller footprint. Have a nice day! :)
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] MJPollard:
The SoC may be the same, but that's meaningless. Having the same SoC doesn't mean that ROMs are interoperable. There are obviously enough hardware differences between the two to prevent the existence of unified 7/7T Pro ROMs. I think you'd be lucky if your phone merely became bricked when flashing an incompatible ROM.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] -=Guybrush=-:
Hello again. My fears proved to be founded, unfortunately. Just tried to flash KOSP 12 for Hotdog on my Guacamoleg. It has been a bit tricky because the partitioning seems different and Guacamoleg doesn't have a recovery partition but I've succeeded with flashing it anyway.

Unfortunately, at first boot I've still got to crashdump mode (linked to the 5G modem according to the message shown, exactly as I was expecting).

Honestly speaking, I haven't ever thought for a split second it could work but who knows? If you don't try, you don't know. It could even be like Xiaomi which releases the same mobile under different names for the Mi and Redmi line-ups but this wasn't the case. Now I need to restore stock OOS again. I think my poor Guacamoleg is starting to hate me! :( I wouldn't make any other shot in the dark: according to my opinion, the only chance is a port from Guacamole with a different modem (and whatever linked to it) but unfortunately this is beyond my knowledge.

I've just dirty flashed 11/14 build and the lag at initial boot still exists with stock kernel indeed. However, the issue disappears after flashing Galt'sGulch kernel 1.24.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] dbendega:
How can I do it? share the instruction and link to the kernel.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Toutatis_:
Galt'sGulch kernel can be downloaded here. There's also a Telegram channel but we're not allowed to post Telegram links on XDA forums so you'll have to find it yourself.

Just sideload the zip from built-in recovery or flash it with EX Kernel Manager / Franco Kernel Manager, it'll detect Magisk so you don't have to reflash it. That's it.

It may have small lags issue on startup (before opening the camera) , but after many tests it is undoubtedly the most performing ROM ever for the OnePlus 7 Pro (integrated kernel recommended). On PUBG New State and gaming it has no rivals, as well as stability and battery. Really top.

boot.img from Arrow-v12.0-guacamole-OFFICIAL-20211114-GAPPS.zip

I wouldn't say it's «tedious». It takes me less than one minute to extract the boot.img file. I just have to extract the payload.bin file from the ROM archive to the payload_dumper git repo directory, then run:

python payload_dumper.py --images=boot payload.bin

and that's it.

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] hammered58:
I cant take credit for this , I found it somewhere I dont remember where,, but its been working for me and it keeps the bootloader unlocked

1. Reboot twrp/lineage recovery, format data. Reboot bootloader

2. Fastboot boot into TWRP FBEv2

3. Sideload official TWRP 3.5.2.9-0 installer (found on TWRP website). Reboot recovery

4. Copy OOS 11.zip to internal storage. Flash OOS 11.zip. Reboot recovery again

5. Format data in OOS stock recovery & Reboot

6. After boot into OOS 11, just local upgrade rom .zip again, you will have OOS on both slots

3) On fastboot ( fastboot boot twrp nebrassy ) (now with internal storage visible)

4) Copy OOS.zip on internal and flash on both slots with TWRP nebrassy.

@alk3p I have a fix for you. It's about dual sim on specific t-mobile devices that can do dual sim. There was a patch by lineage os which broke this. I had to msm last night to restore full functionality of my sims.

This has been reverted by almost all the rom devs for oneplus 7 series. The commit is https://github.com/yaap/device_oneplus_sm8150-common/commit/bff38b186d9e25283a306cbed3bb6ca93e038e72

Use magisk canary, enable zygisk in settings, setup denylist to block Google playstore and Google play services. Then download the MagiskHide Props config addon and flash it, reboot. Then open up a terminal like termux, and type su, give it root permissions, then force basic attestation, and set fingerprint to anything you want. I usually just set it to oneplus 7 pro gm1917, or pixel 6. Reboot then check if safetynet passes. It should.

I'm testing the latest Dora 237 for the Dev, I confirm that it fixes the lags bug on startup, this time 100% safe. While waiting for the boss to update his Arrow and his kernel, you can use this kernel.

Same here with Galt's Gulch kernel, the lag after boot is completely gone. I rebooted many times and I'm definitely not having it.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] daniel84cs:
Good Grest news. Surely the Dev will insert the fix in the next ArrowOS update. Especially since the thermal management leaves something to be desired. With Dora on CODM I reached a maximum of 41 degrees, with the ArrowOS kernel 47 degrees.

Edit. For now only unreleased kernel Dora 237 fix the lags on startup.

1)Do banking apps work in the latest build?

2)Do we keep widevine L1 or it is dropped to L3?if no, then is there any way to get it back without changing the rom?

3)Does it provide free storage on Google photos like pixel experience?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] daniel84cs:
1) Yes

2) If you have L1 you have L1 on Arrow

3) No
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] -=Guybrush=-:
The approach makes absolutely sense and I agree it is the only one possible. Unfortunately, it's impossible to do with KOSP 12 for Hotdog nor ArrowOS 12 for Guacamole because neither of the packages contains a modem image while the stock OTAs do (modem.img and also an mdm_oem_stanvbk.img which, at least by its name, could be something connected but at that point there is also an oem_stanvbk.img for example...).

I don't know what to do and I would only be shooting in the dark so I give up on that side. I need to accept to remain on stock Q because help from the devs is needed but I completely understand they have more useful things to attend to than working at a device which is owned by a very limited number of users. That's it. Thanks for your advices and have a nice day! :)

I dirty flashed 11/14 build over 11/11 build just fine. I think you meant we have to go through the regular flashing process to update, as OTA isn't available for now. But this is not "clean" flashing, we don't have to format data.

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] daniel84cs:
1) Flash latest Dora 239 for fix this issue.

2) This is normal, the warp charge acts only for a small part of the recharge, on all roms, including oos, the last part of the charge is performed slowly.

3) All Aosps roms have for now it , it is not a bug, on all of them it is so, even on the pixels, they have to implement a custom function, which allows you to hide the gesture bar.

Hello, I want to thank you for this ROM. Most things seem to work very well, which is great regarding the short developing time.

I just wanted to mention some things that I've noticed in the first days of trying. First, Android System Intelligence is not included in this ROM and Google Maps driving mode appears in the settings but doesn't work, when activated. I don't know, if you can do anything about that.

And then there are some features, I've already seen in other ROMs which would be nice to have. The Google weather widgets don't show in the widget drawer, although they did in other ROMs I've tested. It would also be cool, to get the Monet theming on Gboard, maybe you can integrate that. And lastly it would be cool, if it was possible to change the icon grid size to 5x6 on the home screen.

Otherwise I really like this ROM and am looking forward to future developement. Thank you very much for your hard work!

Alternatively, you can use this payload dumper tool instead, which is written in go: ssut/payload-dumper-go

Pre-built binaries for Linux, macOS and Windows can be downloaded here and there's also an AUR package for Arch Linux users.

I've just tried it and it works just fine. You don't even need to extract payload.bin file from the ROM.zip first, you can directly use the ROM.zip file. Extracting only specific image(s) such as boot.img is also supported with -p option, e.g.:

payload-dumper-go -p boot ROM.zip
