[Help] Error when flash magisk, rom with twrp - Realme X2 Pro Questions & Answers

Device: X2 Pro
When I flashed stock rom with twrp, it read:
"Mount: failed to mount / dev / block // bootdevice / by-name / userdata at / data: Device or resource busy"
It's still done, but I need to format data and wipe it to boot, otherwise it will go into twrp.
When flashing magisk file also has the line:
"dtbo image: / dev / block / sde17"
It still completed, but could not be booted up. I have to flash the stock rom to boot again.
I cannot root my device, please help me.
Thanks!

Boot into your phone system and go into Developer Options. Uncheck the "Update Cyanogen Recovery" option

Vendor and Product partition error

Hi,
I have à problem with my P9 EVA-L09 when I 've wanted install renovatio rom.
Installation stopped. I ve restarted the phone and when i wanted wipe data i had errors:
Failed to mount /cust (invalid argument)
Failed to mount /vendor (invalid argument)
Failed to mount /product (invalid argument)
Now i can't install any rom ( before i had installed linear os) I can not boot to stock recovery or erecovery. I can just start boot on twrp.
On twrp terminal i format cust partition(/dev/block/mmcblk0p42) this solved cust partition error.
But i no found partition for /vendor /product
I ve downloaded full huawei firmware.
I ve extracted update.app with huawei extractor software.
I ve copied vendor. Img and product. Img on p9 memory
On p9 memory :
Cd /dev/block/bootdevice/by-name
Dd if=sdcard/vendir. Img of=vendor
Now i ve vendor file system in bootdevice but when i do a ls-l I've :
Cust-> mmcblk0p42
Vendor
Vendor has not link to partition.
I try make4_fs -l 512M vendor
Mke2fs -O journal_dev vendor (on bootdfvice directory)
But still not vendor partition and when i try wipe ive now
Failed to mount vendor (such on device)
I wanna ask you how to repair vendor and product partition. And if you can send me a tree of your mmcblk0 (fdisk /dev/block/mmcblk0 and p command) for see if i have the same.
Sorry for my bad english
Thank you
What version of twrp are you using?
Did you ever find a fix for this?

Hi, you've been able to work it out.
I don't see the Vendor partition either, after a bad flashing, I lost CUST, with the commands you use I was able to recover it, but it seems that the 3rdmodem and Vendor folders are not correct either, the first one is empty, and Vendor is not directly found.
With all this I haven't been able to start the system yet, I guess that's why.
See if it's possible that we can help each other.
A greeting.
P.S. my terminal is the p9 plus
P.S.2 By the way, if I try to start the recovery mode, a screen similar to the bootloader one appears, and if I try to recover the system with the 3 buttons protocol, I start TWRP, I don't know if it happens to you too, the fact is that even though I flash the original Recovery 1 and 2, they don't work as expected.

Error installing Magisk

Hi.
I currently have super su installed and the device is rooted. However, what I want to accomplish (pokemon go spoofing) requires magisk. Its android 8.0 and I have twrp. When I go to install magisk via twrp, I get roughly this:
- Mounting /system, /vendor
- Target image: /dev/block/sda5
- Device platform: arm64
- Constructing environment
- Unpacking boot image
- Checking ramdisk status
! Boot image patched by unsupported programs
!Please restore stock boot image
- Unmounting Partitions
Updater process ended with Error: 1
Error installing zip file '/sdcard/Download/Magisk-v17.1.zip
Updating partition details...
...done
No idea what to do from here. Do I need to get rid of super su? and how would I do that? Thank you all in advance.

How to patch `system.img` to root the Samsung S10 5G (Qualcomm) device?

Hi All,
Device Detail:
- Samsung S10 5G
- Qualcomm Device
- Model: SM-G977U
- ROM: VZW-G977UVRU2ASH7-20190827135903
- Kernel-Version - Linux version 4.14.83-16633035 ([email protected]) (clang version 6.0.10 for Android NDK) #2 SMP PREEMPT Wed Aug 14 16:23:48 KST 2019
Background: I have
- rooted the device with instructions given by Magisk.
- I can successfully reboot to the recovery rootfs.
Problem: I am trying to modify the `system.img.ext4.lz4` file to root the device with normal boot. I am aware that it will not let the device install OTA Updates.
Unpack-Pack System and make new AP.tar, flash:
- Without any modification to the `system.img`, I have just unpacked `system.img.ext4.lz4`->`system.img.ext4`->`system.img`->mounted to system directory and packed it back to `system.img`->`system.img.ext4`->`system.img.ext4.lz4`.
- Replaced unpack-packed `system.img.ext4.lz4` with the AP `system.img.ext4.lz4` and make a tar of it.
- Then I have flashed it using Odin v3.13 along with BL, CP, and HOME_CSC.
- Odin has show PASS and I have rebooted the device into recovery mode.
- Done the Wipe data/factory reset and reboot to recovery again but released the recovery key combination on splash screen as mentioned in the root instructions .
- The device stuck in a boot loop.
Tries:
1. Disable Dm-verity
- Removed `avb` flag from `boot.img` with
Code:
magiskboot dtb boot.img patch
- Removed `avb` and `verify` flags from `dtbo.img` with
Code:
magiskboot dtb dtbo.img patch
- Patched `ramdisk.cpio` with
Code:
magiskboot cpio ./initrd 'patch false true'
Patched `boot.img` and `dtbo.img` is working fine with magisk patched AP file but the `ramdisk.cpio` creating the issue: Stuck at splash screen when trying to go to recovery after successfully flash with Odin. Download mode is appearing on splash screen.
So, I have used `boot.img` and `dtbo.img` along with unpack-packed `system.img.ext4.lz4` but the result is still a boot loop. I have also tried a combination of `boot.img` and `dtbo.img` along with unpack-packed `vendor.img.ext4.lz4` and flashed the AP.tar with other files but still the result is a boot loop.
So, I want to debug the problem and got to know about `pstore` which preserve the logs when kernel panic.
2. pstore
- Checked that `/sys/fs/pstore` is mounted by the system with following in init file: Grep the pstore using `find . | grep '\.rc' | xargs cat | grep pstore -n -i` and get following result:
Code:
314: # pstore/ramoops previous console log
315: mount pstore pstore /sys/fs/pstore nodev noexec nosuid
316: chown system log /sys/fs/pstore/console-ramoops
317: chmod 0440 /sys/fs/pstore/console-ramoops
318: chown system log /sys/fs/pstore/console-ramoops-0
319: chmod 0440 /sys/fs/pstore/console-ramoops-0
320: chown system log /sys/fs/pstore/pmsg-ramoops-0
321: chmod 0440 /sys/fs/pstore/pmsg-ramoops-0
- Checked the kernel config by pulling the file from /proc/config.gz.
Code:
$ cat config | grep PSTORE
CONFIG_PSTORE=y
CONFIG_PSTORE_ZLIB_COMPRESS=y
# CONFIG_PSTORE_LZO_COMPRESS is not set
# CONFIG_PSTORE_LZ4_COMPRESS is not set
CONFIG_PSTORE_CONSOLE=y
CONFIG_PSTORE_PMSG=y
CONFIG_PSTORE_PMSG_SSPLOG=y
CONFIG_PSTORE_RAM=y
- Check the `ramoops` configuration:
Code:
./sys/module/ramoops/parameters/console_size 262144
./sys/module/ramoops/parameters/dump_oops 1
./sys/module/ramoops/parameters/ecc 0
./sys/module/ramoops/parameters/ftrace_size 262144
./sys/module/ramoops/parameters/mem_address 3241148416
./sys/module/ramoops/parameters/mem_size 1048576
./sys/module/ramoops/parameters/mem_type 0
./sys/module/ramoops/parameters/pmsg_size 262144
./sys/module/ramoops/parameters/record_size 262144
`pstore` setup looks fine but when I am trying the get logs from `sys/fs/pstore` then I found nothing.
I have tried it by two ways:
1. Crash manually with panic kernel using:
Code:
echo 1 > /proc/sys/kernel/sysrq
echo c > /proc/sysrq-trigger
Followed Reading Kernel Logs
2. Flashing non-working rom that cause a boot loop and then flashed a working ROM with rooting steps and checked the file at `sys/fs/pstore`.
I need a favor in:
- Any steps to fix/debug the `pstore` problem?
- Any other way to find the kernel logs?
Update 1: I get the logs from recovery but I am not able to identify the problem.
Logs link: https://drive.google.com/file/d/1b-XNmjpYvH-L8lY0xA0SYr7XcITVCrVS/view?usp=sharing
Description: In this video, I have done the following:
1. Displayed recovery logs before: The last recovery logs are ends with 8.
2. Rebooted the device with a recovery key combination. I have already wipe data partition before making this video.
3. The boot loop happens and in the next reboot, I have pressed the recovery key combination to open the recovery mode where logs that end with 9 displayed.
4. Then I have recorded `last_history`, `last_avc_message_recovery`, `last_log.9` and `last_kmsg.9`
5. `last_history` and `last_avc_message_recovery` looks unchanged(same as before boot loop).
6. Then, I just have tried to mount the system but that didn't work.
7. At last, I have just rebooted the system normally without any recovery key combination.

Is anyone have experience in detecting problems from the kernel logs?
i can not help you, but we can collect ideas. what about re-sign the system.img? there is a key somewhere, i guess just deleting won't work but maybe it is possible to calculate checksum
or maybe you can switch to SuperSU 2.79 SR3 (latest release from chainfire) or at least look inside the update-binary shell script how to root system.
regarding dm-verity i would start with searching for "verify" flag in your fstabs and remove it. magisk is also doing some hex patches and re-signing, it's the best source to look inside magisk installer zip update-binary/ updater-script, if you have the knowledge to read code
another option is try to port a twrp recovery from another snapdragon (i wonder if somebody did this already) if you can find a porting guide

@Vats12 has already successful rooted with magisk in recovery. this thread is for rooting system (kind of rooting where su binary is placed in /system/xbin like for older devices, which breaks OTA)

Yes, do you know how to do this?
Magisk (guide) does a lot of other things too..
Maybe we can use Magisk to disable the securities and then SuperSu can help in the rooting system?

I don't want to be the one who shouts fake, but the instructions you gave a link to says you have to be able to flash a bootloader first, which means an unlocked blootloader, if you have Verizon rom this is not possible, as the blootloader is locked.
If you did find a way to flash a modified bootloader, or a modified recovery those are the instructions we need, because in fastboot you are unable to do this with a locked bootloader and you are unable to unlock the bootloader on Verizon. If you have a modified bootloader or recovery flashed on your device what did you use to flash it with Odin? Because only way to flash a boot.img is either get into download mode and flash with Odin, or with Edl, if you got into edl mode then can you provide instructions on that, because we would like to know how to get the device into EDL mode as well
Sorry boys this is a hoax.
@DroidisLINUX there is video proof in OP, and again for you:
This is not a tutorial about unlocking and rooting, it is a question how he can modify /system to permanently integrate su

K01A ME70C I can only accesso to fastboot

I all I have an old memopad that I would like to revive for using I in a project. Afetr upgrading to lollipop for mistake I tried to boot in recover through rom manager and obviously it failed
Now I am stuck , I can load fastboot mode and it show unknow bootloader. How Can I revive it?
update:
I followed this tutorial https://forum.xda-developers.com/memo-pad-7/general/downgrade-asus-memo-pad7-me70c-t3735665
I managed to install the temp recovery but I am unable to mount the sd card.
The error seems in the partition structure.
I: Can't partiton unknown volume : /emmc
I Can't patition non-vfat : datamedia
W: failed to mount /dev/block/platform/intel/by-label/ fata ( invalid argument)
