[Razer Phone 2 Guides, News, & Discussion] SimonFoxcoon:
Hello, I'm new to this, so sorry if I'm asking a dumb question.

If I want to have arter97 kernel + TWRP + Android 10 GSI would I do the steps in this order?

Basics > kernel/twrp > GSI > safetynet?

I'd like to use the latest phh 10 AOSP GSI linked here:

github(dot)com/phhusson/treble_experimentations/releases/tag/v222

Thanks in advance.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
yes that is correct
[Razer Phone 2 Guides, News, & Discussion] SimonFoxcoon:
Do I used TWRP or fastboot to flash Android 10?
[Razer Phone 2 Guides, News, & Discussion] liammc83:
Twrp works just fine for gsi

Seems to be a personal preferred.
[Razer Phone 2 Guides, News, & Discussion] Shadoe_Lance:
Cant get safetynet to pass no matter what I do. Any ideas?
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Do both basic integrity and cts fail?

Also do you have xposed?
[Razer Phone 2 Guides, News, & Discussion] Shadoe_Lance:
Yes. Both failed before and after exposed installed.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Exposed is the problem

are you on a GSI? (remove exposed aswell)
[Razer Phone 2 Guides, News, & Discussion] Shadoe_Lance:
It failed both before and after exposed was installed. Yes. Lineage OS GSI
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Make sure to not have exposed, also I'll send a guide very soon on how to fix it
[Razer Phone 2 Guides, News, & Discussion] Shadoe_Lance:
Ok. I'll be waiting for it. I already did the secure file in phh folder. Did not work either.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Oh I was about to recommend that, did your phone restart itself after you clicked securize?
[Razer Phone 2 Guides, News, & Discussion] Shadoe_Lance:
Yes. It asked for root then restarted. Nothing worked.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Oh that's interesting I've not heard of it before...

maybe reinstalling the stock ROM then going back to the GSI could help.

I'm sorry that I can't help more
[Razer Phone 2 Guides, News, & Discussion] Reznor7:
Has anyone solved the low volume game music issue with GSIs? It's the only bug I can't squash. In some games, the music fades in and out at levels below half volume.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
I've never seen that bug, sorry about that.

What GSI btw?
[Razer Phone 2 Guides, News, & Discussion] Reznor7:
Havoc and LineageOS
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
Ulysses i flashed the boot.img in both boot_a and boot_b and twrp is saying this (photo). Obviously I'm screwing the boot.img part of the process and probably even more...twrp is not loading my storage. I'm a novice at best...i hope the info is enough...if you need more please let me know
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Okay so what are you trying to do? just install TWRP? install a GSI etc...

also can if you can boot back to system tell me
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
It attempts to boot into system then after maybe 2 min...it takes me back to twrp but with this msg
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
Other two photos of it showing that twrp sees my system data, vendor data, etc.
[Razer Phone 2 Guides, News, & Discussion] Usyless:
did you do anything else to the phone? or just install arters kernel?

I'd probably recommed reflashign stock then starting over (you will lose your data)
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
No this was my first flashing anything on it...so was I supposed to just pull the boot.img out of the arters97.zip...cuz I extracted it down to a folder from the zip...was i supposed rename that entire zip boot.img?
[Razer Phone 2 Guides, News, & Discussion] Usyless:
you were meant to download the .IMG file from arters website, flash THAT file with your computer, then enter the recovery and flash the ZIP file inside TWRP

you did the wrong thing...
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
So the other contents except the boot.img didn't get flashed...I don't think
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
Ok so just reflash a slot b slot with boot.img file
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Do this...

go onto arters website and download the .IMG file of the kernel, flash that onto both A and B using PC

then the .ZIP that you downloaded flash inside TWRP after you flash the IMG with pc
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
Ok Ulysses. Hey man thanks for holding my hand. I'm bout to go give it a shot
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Good luck, just remember

the IMG file is flashed on pc, the ZIP file on the phone
[Razer Phone 2 Guides, News, & Discussion] ATAC_2000:
Okay Ulysses so the problem seems to be that that around 90% of the paths couldn't be located or "doesn't exist" and even if they are there just not recognized by the flash_all script once Its activated...I tried to simply to reflash the correct img files this time around before I tried the stock firmware
[Razer Phone 2 Guides, News, & Discussion] Usyless:
Did you unlock your bootloader correctly?

both critical and normal partition?
[Razer Phone 2 Guides, News, & Discussion] vkbluestar:
Hey guys, I ran into this error while trying to flash the boot.img. This is what I got

C:\ADB\platform-tools>fastboot flash boot_a boot.img

fastboot: error: cannot get boot partition size

Hoping someone can help me. Thanks a lot!
[Razer Phone 2 Guides, News, & Discussion] Usyless:
did you unlock both critical and normal bootloader partitions? also can you even boot to the phone?
[Razer Phone 2 Guides, News, & Discussion] vkbluestar:
Yes! I managed to unlock both normal and critical bootloader by using fastboot flashing unlock and fastboot flashing unlock_critical. On the fastboot mode menu of my phone, it said device state - unlocked.

Can you tell me the requirements to boot to the phone? It's my first time doing this. I don't think it is the USB port nor cable because I managed to unlock bootloader with it. One thing to note is that I do not have a SD card currently.
[Razer Phone 2 Guides, News, & Discussion] Firedrake1:
Hey, all. So I followed the guide, and installed Lineage. Everything works, but I can't get Safetynet to pass.

It fails basicintegrity, and ctsProfile. I did not install Xposed. I did install the "ARCore/Playground Patcher" like the guide said. It made me update to Magisk 20.4, but I didn't let it update to the newest version.

I confirmed Magisk Hide is enabled for Google Play Service, and all of the options are checked in there. Has anyone encountered this?
[Razer Phone 2 Guides, News, & Discussion] Usyless:
I know the fix to this, one thing though. I specifically link to magisk 20.1 since it does not have DTBO issues (where recovery eventually wont open)

The fix quite simple, but you need to follow closely, and you need to transfer a file using TWRP, are you capable of doing that?
[Razer Phone 2 Guides, News, & Discussion] Firedrake1:
Yes, I am very comfortable doing that.

I only upgraded to 20.4, because the ARCore module will no longer install if you have lower than 20.4. If there is a way around that, then I would be happy to do it.
[Razer Phone 2 Guides, News, & Discussion] Firedrake1:
Do you have that guide/files I can use? Thanks!

I had updated my post. Any recovery with vendor support or any Android 10 arm64 should work. It's always recommended doing clean flash, e.g. full wipe when you switch between different ROMs. You may still try to do keep your data partition, but please don't report any bugs until you can reproduce them with clean flash.

Thanks for this awesome ROM,its smooth n fast.everything works perfectly without a glitch.what I did first was changing orangefox recovery to op unofficial twrp via team win apk,without formatting it shows error in twrp n flashing with magisk it did boot up but to twrp again n flash again without it yes it works.I m okay with less customizations.BTW I m using official open gapps nano.Hats off to you.

What you mean by wipe vendor partition"s"?

I understand that I should wipe system, data, cache, dalvik, vendor?
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] michal778:
Well, a huge disappointment can't flash lineage-17.1-20200628-UNOFFICIAL-rolex.zip at all. I'm using miui 9.2.6.0 and twrp that you posted. Can't wipe vendor because it's not showing in wipe list, so I'm wiping rest. It's says flashing was successful, but gapps giving error 30 and tells me my android is 7.1.2! Something is wrong. I'm doing clean flash from miui. It's not installing at all, so OS is broken or twrp posted. You tried that twrp?

EDIT: Yup it's twrp thing, i used another that allowed me to wipe vendor, and gapps now flashing. Sir, next time better check please.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] yurikoles:

First of all I wanna thanks the devs for this "smooth af" ROM. ;) But I need an help though,

I'm trying to patch Tingle on my Xiaomi Redmi 4A via ADB for enabling system spoofing signature for microG. But I'm getting this error : *'ADB Root access is disabled by system setting - enable in Settings -> System -> Developer options'* everytime I type adb root in cmd (running as admin). My device is rooted with Magisk 20.4 and the 'Super Access' option is enabled as "Apps and ADB". I've also enabled "Android debugging" option under the 'Settings -> System -> Developer options'.

[[IMG="Screenshot 1"]https://i.stack.imgur.com/kGzHS.jpg[/IMG]]

But I'm unable to find any option called 'ADB Root access' or 'Root Access' under 'Settings -> System -> Developer options'. I've also tried abdb Insecure by Chainfire.I've also tried abdb Insecure by Chainfire.

[[IMG="Screenshot 2"]https://i.stack.imgur.com/Xmjwb.jpg[/IMG]]

But with no luck, the problem still persist. I just want to get root access in my adb interface to be able to use Tingle.

Thanks in advance! Any kind of help would be highly appreciated. <3

Great rom sir. But i have a problem.

I ve always heard people saying that Lineage OS has a really good battery life but in my case thats not happening. Although there is no drainage problem but battery usage is not good though and if using the whole day, ive to charge my phone twice a day. I converted from Pixel experience rom due to this reason but the same is happening at this rom . Can you tell me the possible reasons (or any suggestion/fixes) for that? (Or any advices) I'll be waiting for your reply. Otherwise this is a great rom. Great performance and till now no bugs found. Really good work.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] babyyoda:
Depend on your usages and date of your device

totally depend upon how you roughly use your phone if it gives idle 4-4.5hr backup its more than sufficient for 3000mah battery.. if you are playing games continuously than its obvious gives less battery life.. however if you still want some extra battery life try some hibernation apps like Greenify and etc.. but remember it wont gonna boost your 4hr backup to 10hrs backup..

[Meizu Pro 5 Questions & Answers] sHR00m:
Since all the roms are gone I was hoping to at least get Flyme nougat, which apparently flyme 8 is based on.

The problem is that flashing Flyme 7 or 8 china all result in a bootloop. The page says I should install 7 stable first, which I did. No difference. I do this with bootloader and recovery removed because I don't want to lose the unlocked bootloader. Does anyone have an idea what the problem is here? I was thinking maybe its me trying to keep the bootloader so I even tried to flash full stock but that didn't work either. I know how to reverse this but Im pretty much out of ideas at that point to get these images work.
[Meizu Pro 5 Questions & Answers] hall.cool:
did you replace bootloader file with unlocked_bootloader and recovery file with twrp_recovery? this will let you bootloader still unlocked and recovery still TWRP after you flash it.
[Touch Diamond, MDA Compact IV General] MasK:
Dear fellas,

Although this topic has been briefly discussed in various locations, it hasn't gotten "big" enough.

I know a number of ya guys are having this problem. The touch-sensitive action button used to focus does not focus the camera (and yes, I have set it to "touch & press").

Mine works intermittently, in fact, doesn't work most of the time. I know it's 100% not a hardware problem, as the button lights up and brightens up my screen according to normal behavior. Now I'm wondering, for those guys who don't have this problem, do U have a different version of the camera app?

K.. mine's the stock HK 1.93.831 ROM and my cam app is version 6.00 (build 31516).

I'm not sure what causes this problem. Although I'm not a camera freak, but this prob makes my baby "imperfect".

Pls post yr ROM and camera version (I wonder if there's a difference) and state if youre experiencing this problem. Thanks!
[Touch Diamond, MDA Compact IV General] zk_69:
Hi MasK,

I'm having the same problem as you, the "touch & press" feature didn't work most of the time.

I'm using HTC SG ROM 1.37.871.3, camera version 6.0 (Build 31364).
[Touch Diamond, MDA Compact IV General] GeckoDev:
I used to think the camera didn't focus properly until I took some time to play with it. It's pretty slow, but mine seems to work. When I touch the button, it will take anywhere from 1-5 seconds to focus, and then the cross-hair turns green and beeps to indicate focus lock. At first I didn't realize I needed to wait for the beep, so my shots were out of focus. :) Seems to work fine now that I know that.

I'm currently on stock 1.37.401.3 with camera 6.0 Build 31364 ... same as previous post, just a different ROM region, which I doubt makes a difference.
[Touch Diamond, MDA Compact IV General] rumpleforeskin:
i have a similar problem where i run the camera app, then the 1st time i place my thumb over the button nothing happens, but if i take my thumb away and try again it will work fine.

It will continue working fine untill i restart the camera app, just never registers the 1st attempt.
