[r14] arter97 kernel for Razer Phone 2

Search This thread
Flashing r14 over r12 still causes the phone to freeze at the boot logo. r12 working fine though (MR2).

I tried the same thing today. I had r12 installed from when I got the phone in January with MR2. Today I downloaded r14 and the patched boot.img for MR3 and tried flashing them but now i'm stuck on the razer boot logo. Going to try restoring my backup from earlier. Anyone know what I did wrong?
1. Ran flash_all.bat from the MR3 update while keeping user data
2. Flashed patched MR3 boot.img in fastboot to boot_a/boot_b
3. Flashed arter97 r14 in fastboot for recovery

Edit: now after restoring backup from before flashing it's stuck on the green loading screen.
Edit 2: for some reason my backup from earlier today only backed up the system partition even though I selected boot and data. Restoring the boot/system from my first backup in January got me booting again.

Do u forgot after flashing the mr3 & keeping userdata to flash the f2fs file in twrp (Magisk?) ?
When twrp works try installing the zip file. Personally I use the tritinty R1 Kernel. I don't know why but R2,R3 & R4 Kernel freezes the half of my Display sometimes.

What app would y'all recommend for messing with kernel settings? I love FK but a lot of options don't stick and get overridden. Core control resets to all 8 online and min/max cpu frequencies keep resetting to default. Any help would be much appreciated!

Hey guys,

I dun goofed when trying to do a routine backup.

Rebooted into TWRP, which surprises me with a password prompt (instead of pattern unlock)
Reboot to system to remove encryption and then fix stuff, greeted by "Enter password to start android" prompt
Tried the numbers-to-pattern trick, no luck. Basically locked out of the phone now
Booted back into TWRP, while looking around for other options, accidentally chose "Slot A" which has gotten me stuck back on the old recovery
fastboot commands no longer work

Code:
D:\adb>fastboot.exe boot twrp-3.2.1-0-cheryl.img
Sending 'boot.img' (23120 KB)                      FAILED (Write to device failed (Too many links))
fastboot: error: Command failed

Trying to re-flash the kernel just hangs:

Code:
D:\adb>fastboot.exe flash boot arter97-kernel-r14-20200428.img

I've got some data I'm not 100% sure is backed up like my 2FA applications so I'd like to try and get this fixed without re-flashing the entire firmware. Not sure if that's possible but I'm open to suggestions

Edit:

Tried switching to Windows Terminal/Powershell and got slightly different error:

Code:
PS D:\adb> .\fastboot.exe boot .\twrp-3.2.1-0-cheryl.img
Sending 'boot.img' (23120 KB)                      FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
PS D:\adb> .\fastboot.exe flash boot .\arter97-kernel-r14-20200428.img
Sending 'boot' (30176 KB)                          FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
PS D:\adb> .\fastboot.exe getvar all
getvar:all                                         FAILED (Write to device failed (Unknown error))
Finished. Total time: 5.004s

I'm sure the TWRP image is still there, but I can't get it back up.

So I was having this exact issue. I seemed to get it both with Arter's kernel and the stock build, so I assumed it was just something wrong in Razer's main ROM. I tried battery calibration and have an app that monitors the battery charge and reported that it is still in decent health. I am far enough along with this phone now that I went ahead and took the plunge into Havoc OS after reading a few of the devs have finally stabilized it for Razer Phone 2. It is day two now and haven't had the hang up problem, but I will let you know after a week if this is still the case.

Im on Pie . Mr1 rooted and with unlocked bootloader ,Magisk is working without any problems. The question is can i just flash this Kernel over or do i need pre version of kernel or mr3 ? Since i don't have twrp i can't backup complete firmware ... :(

I too have this bug on mr3 pie, I've also spoke to several other Razer phone two users on arter who are experiencing this very bug as well.. hoping there will be an update to resolve eventually

Is havoc a GSI? If so can I ask if your phone carrier is an American company? I'm asking because there's a known GSI bug that seems to make SMS not work on any GSI ROM on specifically only American carriers if LTE is enabled and I had this bug personally when I tried Resurrection remix so I'm wondering if havoc has this bug as well? but again if you're not on an American Carrier you'll never even know it existed, it only effects the US

I am also getting this bug, for me it started after installing custom recovery, like you said the only way I found to fix it is to reboot by ADB or holding down the power button for about 13 seconds, for me it's progressed to where if the phone Powers off by itself it gets stuck in a boot loop, doesn't charge, and cant enter recovery. I have to go to the bootloader menu by holding volume down and Power, then selecting the grayed out option so I can hold the power button down and force a hard reset, otherwise it never gets to the green flame animation.

Just a quick question.. Has anyone been successful using r14 with MR5?

Thanks,
RJR

MR5? When did MR4 come out? I am on an unlocked RP2 with no available updates and am running Build #: P-SMR3-RC002-RZR-200226.3141. I also checked for the factory images and that is the latest release on their website. What is your build number and do you have a carrier version? Is me being on the non-stock kernel and being rooted making the check for updates fail? I get that the update process should fail since the non-stock recovery is gone, but I could have sworn previous updates showed up and downloaded but just failed to install with this kernel.

I used the factory image for MR3 and then took all the updates and ended up with MR5 before installing this kernel and switching over to a GSI rom.

Try using Trinity and let us know. Trinity works on rooted MR5..

Install Trinity then install Magisk.

To install Trinity you first need to install r14 that has TWRP. Then use TWRP to install Trinity.

Update: I couldn't use r14 to flash mr6, so I downgraded to mr3. After that I used Trinity kernel and it worked.

Thx rrusek for the info.

I did a clean flash of MR6 the other day, then used r12 without any issue. Trinity is more than I am really looking for, but it's good to know that it's not required to run mr6

    arter97 kernel for Razer Phone 2 with TWRP and exFAT support​

    /* Details */

    Latest CAF msm-4.9 kernel fully merged
    This kernel contains more cutting-edge changes from Qualcomm than the regular sdm845 tag
    Latest Linux 4.9 subversion merged
    Use CONFIG_HZ = 300
    - This changes context switching interval from 10ms to 3.33ms
    - Pixel used this for years and Google recommends other vendors to do the same for fewer jitters
    Memory management improved(from Pixel 2 & 3)
    Pixel's lowmemorykiller used
    DM-verity fully disabled (you can remount /vendor to R/W properly)
    Scheduler commits cherry-picked from Pixel 3
    Timer optimizations
    RTL8152/8153 USB LAN adapter support
    TWRP support with proper f2fs support (see below)
    Permissive SELinux
    Passes SafetyNet
    Built with -O3 speed optimizations
    Built with latest GCC
    Westwood as default TCP network congestion control
    UFS optimizations
    Entropy hook on storage removed
    Latest mainline f2fs support with GC fixes
    CFQ I/O scheduler backported from mainline
    Systemless installation (the kernel itself doesn't touch /system or /vendor)
    Modules support disabled for lighter kernel
    WireGuard support
    Additional exFAT support with modified vold
    Removed RTB(interrupt) logging entirely

    /* f2fs */

    This kernel fully supports f2fs for /data and I encourage everyone to use f2fs with my kernel for better performance.
    See here as to why you might want f2fs.

    Use the integrated TWRP to format /data to f2fs.
    It is crucial to use my kernel's TWRP as it includes an older version of mkfs.f2fs and passes an incorrect parameter to mkfs.f2fs.

    1. Boot to the integrated TWRP and flash f2fs_fstab.zip
    2. Reboot to recovery again
    3. Wipe /data by entering Wipe > Format data > "yes"

    After formatting, or flashing a new ROM or an OTA, /vendor’s fstab needs to be changed.
    Flash f2fs_fstab.zip to convert fstab to f2fs again. f2fs_fstab.zip won’t format your /data partition.

    /* exFAT support */

    This kernel fully supports exFAT via sdfat drivers from Samsung.
    You must use the provided vold to use exFAT as the stock vold doesn't support exFAT.

    You must decrypt your phone before using this vold mod as it doesn't support FDE implementation with Razer Phone 2.
    Following the f2fs guide above is the easiest method.

    Flash vold_mod_arter97.zip from TWRP and you're done.

    I am not responsible for bricked devices, dead SD cards,

    do some research if you have any concerns about features included in this kernel
    before flashing it! YOU are choosing to make these modifications, and if
    you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

    /* Instructions */

    You can use the zip file to flash the kernel from your existing TWRP recovery.
    If you don't have TWRP installed already, you can use the img file to flash the kernel directly from your PC via fastboot.

    Both methods will install both kernel and modified TWRP recovery.
    You can check if the modified TWRP is installed by looking at TWRP's version name.
    It should say "arter97".
