Need recovery which supports last_kmsg or console-ramoops - Huawei P20 Lite Questions & Answers

Hi
In order to debug the boot process on my build of Ubuntu Touch for the P20 Lite, I need to get access to console-ramoops or last_kmsg from my build. Furthermore, I have to use a recovery image that I can flash over erecovery. Currently I am using TWRP-9.1.img (Gaguga), but I get the impression it does not support this. Am I right?
If so, which recovery image should I use?
I realize the kernel of my build also needs to support this. I am checking this also, but not sure which kernel configs need to be enabled, so any help here would also be welcome.

Looks like I found the solution myself. The last recovery mentioned in this guide fixed the issue.

Flash Custom Rom on SGP512 unlocked Bootloader Marshmallow 6.0.1

Hey Guys,
as far as i could find out so far, you use TWRP to flash a Custom Rom from the Tablets Recovery Mode, this requires a rooted device, and to do this you flash a prerooted rom somehow, which includes TWRP already, which you then use to flash the rom you actually want on your device.
Another possibility was to flash a Kernel (with TWRP?) to get the same results...
Now I absolutely can´t find a tutorial for dummies, to do that, or find the required files.
After i found it kinda complicated to unlock the bootloader, since most of the tutorials didn´t even mention you need advanced mode and a special Google USB Driver from Sony´s Developer Page, to even get that working, i would really appreciate if someone could give me a step by step with links.
If a tutorial exists, pls give me a link as well, cause i looked the whole day yesterday, and found jack.
cheers
yes, you need to do all that. i just went through this yesterday and used this tutorial:
https://forum.xda-developers.com/showthread.php?t=2747676
once you are unlocked, follow the instructions for your rom, usually to flash the boot and recovery images with fastboot. two things to watch out for though, if you are using an oreo rom make sure your twrp version is 3.2 or better, secondly, if twrp give an error where it cant mount the partitions to wipe them use the change format option under wipe/advance to change to ext4 (which essentially re-formats the partition) and you should be good to flash the rom after that.
here is another tutorial to help get adb, fastboot, and the drivers up and going:
https://forum.xda-developers.com/showthread.php?t=2588979
answer yes to everything, i can't remember if i loaded in sony specific driver on top of that or not.
goodluck!

Help with rooting Oukitel C15 PRO 3GB V

Hi all,
I'm new here and was wondering if I could get some help.
I recently purchased an Oukitel C15 Pro, which I am now trying to root but without any success.
From my own research, there are 2 versions of the Oukitel C15 Pro, one that is 2 gb ram and another one which is 3gb ram. Mine is the updated version 3gb with V14 build number.
Here is some info:
Build number - OUKITEL_C15 Pro_V14.0_20191121
Baseband - E557_61_P0_LWTG_V0.3.0_S191028
OS - Android 9.0
Processor - MT6761V/WBB - ARMv7 Processor rev 4, 4 cores at 2ghz arm cortex a53
So far I have managed to find the stock rom file and twrp recovery file for Oukitel C15 Pro.
I seem to be having issues with booting into recovery. I have literally tried everything.
I've tried flashing it via adb, trying to boot from adb into recovery etc. I've also tried using the SP flash tool. It does the flashing perfectly fine without any errors as I have already unlocked the bootloader and debugging is on, but the phone just seems to always load into its stock recovery and not twrp.
I've also tried patching the boot file with majisk, again no errors whatsoever, however when trying to boot, it boots into the normal system without any changes being made. I have all drivers installed etc and I honestly have no idea what I'm doing wrong.
I know that on some phones you have to boot directly into recovery after flashing otherwise the stock recovery will overwrite the twrp but again no luck, it just boots into the stock file.
I have also tried booting it via adb directly into recovery once flashed but no luck, normal recovery loads. When I try to do adb sideload I get error E 21 verification failed.
Does anybody have any advice on what I need to do to root my device? Maybe the files I have downloaded are wrong? I have no idea. I'd literally appreciate any help/links etc.
Thank you
You are not alone

Disable dm-verity/AVB if it's enabled, otherwise you wont have any luck flashing a Custom Recovery, a Custom ROM or patched boot
Code:
adb devices
adb disable dm-verity
adb reboot
Help to root
Pls how did u unlock bootloader

touch is not working
you cant fastboot boot on this device so DO NOT flash this to your device without a backup of your stock/current boot image
issues we are having is no touch, can't mount /data, and so far cant boot into system with the recovery installed so if you want to use it youll need to flash this to boot, use it for whatever and then flash stock boot back, if your magisk patched youll need to flash the backup of that patched boot image you made before flashing this in order to get back into your system....... i have sort of found a slight work around for having to keep flashing the boot partitions until someone can get this to boot by placing my current boot image on an sdcard along with the twrp, flash the twrp to the active boot partition, boot into twrp, install image and install your backed up boot image to the current slot, then go back to advanced and install twrp to ramdisk and select and install the twrp image to the ramdisk, if your magisk patched you need to flash magisk zip right now, you can adb shell into twrp to pull a copy of this boot image if you want and i have flashed my "twrp-ramdisk installed boot image" on the Slot that my system is on and stock/backup boot image to inactive slot because its the only way to boot back to system for now without reflashing the stock(backed up) boot image back to the slot. and reboot into bootloader, change active and reboot and your back into your system.... when you need twrp you can set active to the other slot, it will bootloop once into bootloader and choose recovery to get back to twrp... when done reboot to bootloader and set active back to the other slot and reboot into system.............otg mouse works, adb works, mtp works, some work has been done on the touch but thats still not working yet, everything seems to be mounting except data............. big shout out to PizzaG for this
***this is a very round-about way to get a currently buggy twrp on the device but if you have a usb-c adapter and mouse you can navigate twrp....***
PizzaG doesnt have the device and has spent more time than anyone could possibly ask someone to spend on this for free... I dont have the skills required yet to really work on this. I have tested as much as possible and here it is for those who can build and work on it. i dont recommend releasing in its current form because im sure alot of people will be complaining and bricking their devices. if you can build it im sure you can work on it and should have the skills to atleast recover and have the sense to make backups first.......
Thanks again to everyone who has already donated the valuable time working on this for us and to everyone who will follow and build upon this!

heres a compiled boot image from the above tree as of 10/02/2022.
**remeber it DOES NOT boot to system, this is twrp only, not installed into recovery ramdisk yet. so BACKUP YOUR STOCK(current) boot image FIRST**** you will have to flash your stock(current) boot image back to boot back into your system. you can sort of get around this by above mentioned method BUT here it is for the GN2200 anyways. working on my July patched device and my May patched device so it should work for other GN2200 sec patches too...
***BACKUP BACKUP BACKUP*****
also cant change active slot from twrp, must reboot to bootloader to change active slot
Heres TWRP installed to ramdisk on a july patched boot image. does not boot to system but since it doesnt you should still be able to use this on any patch for testing purposes.....
You can backup your boot image and flash your current boot image to inactive slot and flash this to active slot by selecting recovery from bootloader after it loops once.... use twrp then go back to bootloader and change active and reboot to get back into your system.
**BACKUP YOUR CURRENT BOOT IMAGE****
***DOES NOT BOOT TO SYSTEM**
***YOU WILL NEED YOUR CURRENT BOOT IMAGE TO BOOT YOUR SYSTEM< YOU SHOULD ALREADY HAVE A BACKUP OF YOUR STOCK IMAGE IN THE CASE THAT YOU ARE MAGISK PATCHED ALREADY< KEEP A COPY OF BOTH IN CASE YOU DECIDE TO WIPE DATA< YOU WILL NOT BOOT BACK INTO YOUR SYSTEM WITH A MAGISK PATCHED BOOT IMAGE IF YOU WIPE DATA*******
if someone can get their system to boot after installing the TWRP from post 4 or their own build after personal edits please post here how you were able to achieve the install and maintain booting into system..
currently twrp indicates that path to /mnt could not be found and cant mount /data .. i think if someone could fix this maybe some progress could be made

halfway working on mine, just isnt finished yet, we need someone who knows alot more about this than i do. another dev is working on twrp but needs a device. the serial wont affect anything else other than the oneplus care app and getting the unlock token..... other than that u have full functionality.... the one posted above needs ALOT of work to finish. no touch yet but it could work for SOME things....
I know C/C++ at a decent level, however; I don't have much experience with low level stuff (especially dealing with bootloaders and other specific proprietary android kernel stuff). If there is anything that needs testing, I am down for it since this is just a secondary phone for me and I won't be too upset if it explodes.

i just unpacked the twrp image with AIK and made the suggested edits and repacked, reflashed, same...... another person is working on twrp and has gotten much of the fstab corrected in their build but their keeping their source closed til they get it ready for release and is still very far from being finished with it and doesnt have much time to work on it right now so we are just kinda stuck waiting on someone that knows what their doing to help get this going. the other person has touch working on theirs so i know its possible i just dont know how long it will be before we see a beta even

also i see a recovery.fstab instead of twrp.fstab in /system/etc. is this what your referring to?
You need both from what iv read ,. TWRP.flags is a module that rewrites the stab at a certain point which may be the reason it's not compiling but I will post. Recovery.fstab is supposed to be a copy paste from the boot.img and gives the general mount partitions locations,. TWRP.fstab is mounted using the same partitions but different format/flag structure to be available to TWRP .

Interesting article above. Were you able to get that to work? I know it says MTK but seems like mechanism should be the same, or atleast I would assume anyways that the function would be very similar in the case of a flag. Was told you needed to use original kernel but then I couldn't get that to boot period. I'm out of my area of knowledge at this point but always willing to learn.
Also I tried messing around a little with the f stab and TWRP flags I was told that TWRP flags is pretty much the same as the twrp.fstab... also this build needs to have something added to the drivers I do believe that this is somehow related to USB touch it is a goodix gt9886 touch panel using the Samsung 9886 drivers. Maybe the init's need some help here as well.
I have the programming knowwledge that TWRP would require, but have not as of yet created one as my devices were typically readily complete before-hand. Once my device is back up, and running I am going to boot into Ubuntu and give it a go.
I need some excuse to have learned assembly x86, c, c++, Java, Python, and rust and have been eyeing learning scripting so it could be a fun side project assuming it is still incomplete as of the moment?
Is it normal for manufacturers to use components from other's in their builds? The kernel posted seemed to indicate at least a couple Samsung files included.
Well C is a guarantee possibly some C++ as well and definitely some sh scripting if you know rust and know how to attach it to C well enough that could add more possibilities I would imagine. The recovery is from my understanding in the boot image Android Image Kitchen would help you see it unmodified if that is the case.
I found a unofficial TWRP that flashes to the boot partition, and works pretty damn well, id have to say! I am not an experienced developer, I just like to flash around on my phone in my spare time.. Anyways here y'all go:
I am down while I got partitions backed up to the cloud.

Development [RECOVERY][OFFICIAL] TWRP for ASUS ZenFone 9

Official TWRP is now available: https://twrp.me/asus/zenfone9.html
IMPORTANT NOTES:
CleanSlate custom kernel is not currently compatible with TWRP for this device (Kirisakura is compatible as of v2.0.6).
This device has a recovery partition (2, in fact), and fastboot boot is disabled in the bootloader. Flashing TWRP to the recovery partition is the only way to use it.
If you attempt to fastboot boot the TWRP image, your device may end up unbootable. YOU'VE BEEN WARNED.
Any questions, comments, feedback, or concerns should always be accompanied by logs (recovery log, logcat, dmesg)

If you're not on stock kernel, then that's probably the problem. I know the custom kernel situation is different on this device than previous ones. This may be something that @Freak07 & I have to look into together. In the meantime, can you restore back to stock kernel and confirm that TWRP works, and then install Kirisakura and see if everything still works?
Restored stock kernel with kernelflasher but now it wont boot. Tried to change the slot to a but isnt allowed in fastboot.
Have to find out now how to change the slot or install stock kernel via fastboot...

It doesn't sound like you followed the procedure in the Kirisakura thread FAQ to fully return to stock. Can you confirm exactly what you did?
just restored the backup i made with kernelflasher befor i installed the custom kernel and rebooted.

I'm not familiar with that app, sorry. I just know that's not the process mentioned in his thread, so until you do that, I can't really confirm what the problem could be.
ok, im back on stock. flashing following files helped. i will test twrp again later and report. thanks for your replies.
fastboot flash boot boot.img
fastboot flash vendor_boot vendor_boot.img
fastboot flash dtbo dtbo.img
fastboot reboot fastboot
fastboot flash vendor_dlkm vendor_dlkm.img
fastboot reboot
With stock kernel twrp works. Just installed as described on twrp.me. The official twrp app from playstore crashes after root allowing.
For everyone who comes from custom kernel flash the files from your actual firmware (payload-dumper) as described in the post above.
Are you working on custom kernel support?

From stock, I just flashed the Kirisakura zip in TWRP and my device booted up fine.
EDIT: While the above is true, TWRP no longer functions after installing the kernel, and the device won't reboot again after installing it. So something is definitely wrong somewhere.
For now, I can only suggest not using it with a custom kernel until we figure this out.
Ok, flashing with EXKernelManager works also.

I can do reboots but twrp doesnt work anymore

Yes, there seems to be an issue in the kernel that's preventing TWRP from working. I'm not sure what the issue is, unfortunately.
So every time I restore a back up, do I have to delete all lock screen requirements ?
If that's the case, I would have to redo my fingerprints every time

Yes.
Quick PSA for anyone using this TWRP that also wants to use a custom kernel:
As of Kirisakura 2.0.6, the custom kernel and TWRP can now co-exist. This is due to the changes that allowed a monolithic kernel build. Presently, CleanSlate has not adopted those changes, but if/when it does, I will remove that disclaimer from the OP.
Thanks to @arter97, @Freak07, & @tbalden for supporting this device!

Question WIP - Compiling Kernel / TWRP

Hi all,
I have been looking into compiling the kernel and TWRP for this device.
For the kernel, it compiles but does not boot (Will invvestigate later ).
The TWRP does not boot, most likely related to boardconfig.mk. I am unable to find the kernel base or offsets. Can anyone assist in discovering this information? I have tried unpacking boot.img and the current tools does not show this information.

Hello. I manage to create TWRP for this device.
It is currently tested on a device running the laster firmware RUI 4.0_C.13 but it should work in RUI 3.0. Decryption works, MTP didn't yet.
