Here is a fastboot bootable image to boot you into Magisk core-only mode in case you bootloop due to flashing a bad module and TWRP is not enough.

Once in fastboot:

fastboot boot image-newpixel2xl.img

You will boot with root but modules disabled. If something additional is needed, once booted to core-only, unzip the attached zip onto your pc where you can run ADB/fastboot and run the bat file. It will push .disable_magisk to your cache folder so that your modules will be disabled even after a reboot (zip says crosshatch but will work on any phone)

Can u tell me what kind of problem fix with this update
[Samsung Galaxy A50 Questions & Answers] NoCo33:
It updates the security patch to october. And that's pretty good. I guess Samsung is not going to improve this firmware any further. Camera won't get any better because the sensor is too small for 24mp, although it's not bad considering the price, and fingerprintsensor also has improved a lot. It just needs to be set up right, and many users don't seem to succeed.

My only reason now to prefer an s series phone over a50 is the camera.

Hi,

I have a bit of a challenging dilemma.

I managed to break the screen of my 02 exec this morning, i recently bought a new vista laptop and as yet hadn't backed up my contacts. It doesn't have Outlook and I was wondering if there was another piece of software to back contacts up with that won't involve installing onto my phone as can't see to do that.

o2 collect phone in 24 hours to replace with new orbit2.

All advice greatfully recieved.

Tools needed: boot.img extractor. I recommend the one created by osm0sis from this thread:

https://xdaforums.com/sho....php?t=2073775

The first method was developed by osm0sis and removes magisk and all modules.

1. Unpack magisk_patched.img

2. Unzip overlay.dremove1.zip and place overlay.d folder in ramdisk folder.

3. Repack IMG

4. fastboot boot image-new.img created by repacking 8mg

This method is an offshoot of osm0sis version but boots core-only mode. Afterwards, remove the .disable-magisk file from the /cache folder for modules to work. Dot files are hidden files so if your root explorer can't see hidden files, run the "Remove disable_magisk" bat file in ADB.

1. Same as above but use the overlay.dcoreonly1.zip

For both methods you must be rooted for it to work. These are not cure all's for all bootloops.

Remove .disable_magisk bat file

****************************************

Here is a fastboot bootable image to boot you into Magisk core-only mode in case you bootloop due to flashing a bad module and TWRP is not enough.

Once in fastboot:

fastboot boot image-newpixel3a.img

You will boot with root but modules disabled. After you remove the offending module you will need to go to /cache folder and delete the .disable_magisk file before your modules will work.

fastboot boot image-newpixel3aRemove.img

This one should remove magisk and all modules, then reboot and magisk should reinstall itself (ask to install necessary binaries). This is what osm0sis uses to recover from failed flashes. See this post:

oh my gosh would you believe i desperately needed this on tuesday and, after several hours spent trying unsuccessfully to get magisk manager for recovery working, ended up reflashing and starting again from scratch! crazy timing. anyway thanks for this, will definitely come in handy as i am too stupid to learn from my mistakes, ever.
[Google Pixel 3a Guides, News, & Discussion] Skittles9823:
Relatable. I've had to hard wipe twice as I'm not used to this a/b stuff without TWRP lol. I've learnt my lesson though and finally granted shell root access, so assuming the phone boots past the bootloader I can use adb to fix up my magisk install.
[Google Pixel 3a Guides, News, & Discussion] benji:
Thank you! I've been running the stock kernel for the past several days because of a borked Magisk module. I couldn't fix the problem through TWRP since I'm on Android 10. This boot image allowed me to get back root without wiping. So thanks again!

Do you mind explaining how you made the image? I saw on the Magisk website that such a thing was possible but was unable to actually find details on how to create a core only image.
[Google Pixel 3a Guides, News, & Discussion] Tulsadiver:
You have to build your own copy of magisk from GitHub.

Clone magisk

Go to native/jni/core folder and edit the boot stages.cpp file in notepad++ like this:

Approx line 667

If (access(DISABLEFILE, F_ok) ==0)

Change == to !=

Now build magisk as per instructions on GitHub

One you have built it and there were no errors go to native/out/armeb-v7a folder and get a copy of the magiskini64 file.

Unpack a copy of your magisk_patched.img.

In the ramdisk folder replace the init file with the .magiskini64 file (rename to init)

Repack your magisk_patched.img

The results are a patched IMG that will boot core only mode.
[Google Pixel 3a Guides, News, & Discussion] Bramton1:
I definitely need to make sure I have this handy. A few questions, if you don't mind.

1. I would assume one should make a new version everytime they update to the latest security patch, correct? For example, I should not use a patched boot.ing from the December patch if I'm on the January, patch, correct?

2. Do your instructions assume that someone already put a .disable_magisk file in /cache, or does the boot.img itself do that job?
[Google Pixel 3a Guides, News, & Discussion] Tulsadiver:
To update boot would be best but you are just booting the image, not flashing. The old method required building a modded version of Magisk. The new method you just unpack the magisk_patched.img and drop in the overlay folder.

The boot image installs the .disable_magisk file for you.

[Google Pixel 3a Guides, News, & Discussion] Velcorn:
Thank god for this one. I almost did a fullwipe because I couldn't get Magisk to work after flashing the March factory image in order to update. Turns out I forgot to remove your center clock/battery icon gone module. I didn't expect it to be the culprit, but it seems it was. Regardless, I'm back to working root after days of trying to find a fix :P

Is it possible to fastboot boot (not flash) the modified boot image for disabling modules and then install Magisk via Magisk Manager?
[Google Pixel 3a Guides, News, & Discussion] zgfg:
You should be able to boot with the modified image, but you don't "install" Magisk then - Magisk is already installed, just you booted with all the modules disabled

Just open Magisk Manager, go to Modules and mark to remove the module(s) causing bootloop.

Pay also attention to remove

.disable-magisk file from /cache

as described in OP post #1

Then reboot with your proper Magisk patched image (no more Core Only) and if you have removed the module in the previous step, this time you should be booted to Magisk with no bootloop and with your other modules re-enabled again
[Google Pixel 3a Guides, News, & Discussion] cucumbersmell:
I used Tulsadiver's core-only boot.img for the OP7T to root the phone by fastboot booting it and then using Magisk Manager to install to the active and inactive slots. Was hoping the boot.img for the 3a would work similarly. Was nice and simple and saved the time of having to download and patch the boot.img.
[Google Pixel 3a Guides, News, & Discussion] Tulsadiver:
It is based off of a magisk_patched.img so you might be able to use it like that. You would need to remove the .disable_magisk file from the cache folder though. This is a little different than the one I helped out with on the 7T forum.

[Samsung Galaxy Note 9 Questions & Answers] Bicka0701:
So let me give you a little background first. I was at my brother's house recording him dunk in superslowmo. All of a sudden, my phone freezes. After about 2-5 mins I decide To hold power +volume down and the phone goes black and goes to the "Samsung Galaxy note 9 secured by knox" screen and does a infinite reboot to that screen. The phone will not go into recovery mode BUT will go into Download Mode. I tried letting the phone completely drain and then trying it with no success.

I do have AT&T protection on my device but the only thing they will do is replace it which I'm trying to avoid being that I have pictures I want to extract from the phone.

So to my question(s)

1) if I flash latest version of firmware from sammombile will I lose my pictures? (Trying to avoid loss of pics)

2) can I use a MacBook to do the reflashing or does it have to be windows?

Please and thx to all that respond!!!
[Samsung Galaxy Note 9 Questions & Answers] butchieboy:
Once in download mode hold volume down and power to see if phone boots up. If you reflash with Odin use home_csc so it does not wipe your data. If you do get to recovery do not do a wipe, everything you have saved to phone storage will be gone. See if you can get to device storage by connecting to computer once your in download mode or recovery. If so just move all important files to computer then you can use Odin to flash firmware.
[Samsung Galaxy Note 9 Questions & Answers] Bober_is_a_troll:
1) while flashing in Odin, the CSC file determines if your phones data is erased or not during the flash. In order to retain personal data, flash HOME_CSC..

2) you can use Jodin to flash on a Mac https://xdaforums.com/devdb/project/dl/?id=20803

Just a heads up, Google photos has free backups up to 15gb in full quality, or unlimited backup of 1080 for pics and videos. So at least from now-> forward a hardware issue won't ever cause you to lose pics again. You just need to open the app and setup backups.

Ohboy this is helpful. Just out of curiosity, how does one create a magisk patched boot image with core-only mode enabled? I would like to be able to make my own every time a new security patch is out.
[Google Pixel 3a XL Guides, News, & Discussion] Tulsadiver:
I had planned on keeping these updated but here are the instructions.

You have to build your own copy of magisk from GitHub.

Clone magisk

Go to native/jni/core folder and edit the boot stages.cpp file in notepad++ like this:

Unpack your magisk_patched.img

In the ramdisk folder replace the init file with the .magiskini64 file (rename to init)

Repack your magisk_patched.img

The results are a patched IMG that will boot core only mode.

[Google Pixel 3a XL Guides, News, & Discussion] osm0sis:
Should just make an AK3 zip that pushes the init from this boot.img into any boot partition, so will work universally. ;)
[Google Pixel 3a XL Guides, News, & Discussion] Skittles9823:
Ooft.

Wait, can you flash that through adb though?
[Google Pixel 3a XL Guides, News, & Discussion] osm0sis:
Hmm.. true, non-working recovery is a definite problem. I'm in that boat right now on my OnePlus 7T, which is how I came across this thread. :eek:

Okay, better idea. Instead of mucking around with recompiling magiskinit for the above, just do it via boot script in overlay.d :D
[Google Pixel 3a XL Guides, News, & Discussion] Skittles9823:
Tbh, a custom boot.img is the only way to recover in some situations. Like if you can't boot into an adb environment or if you've never granted adb she'll root access.
[Google Pixel 3a XL Guides, News, & Discussion] osm0sis:
Exactly, so a custom boot.img using overlay.d is the easiest way to accomplish that currently.
[Google Pixel 3a XL Guides, News, & Discussion] Skittles9823:
How would one do that exactly without being able to use adb shell?
[Google Pixel 3a XL Guides, News, & Discussion] osm0sis:
overlay.d is built into the boot.img, so you take your latest magisk_patched.img, patch it with the overlay.d scripts to have the desired effect, then repack and flash via fastboot.

Same as the OP likely did, but no need to build Magisk to get a modified magiskinit, since you can do it all via boot script, like I said.
[Google Pixel 3a XL Guides, News, & Discussion] osm0sis:
If anyone wants to experiment with this idea, here's the basic setup I used for my boot.img to fully reset the /data/adb directory for the soft brick issue (related to a magisk.db failure) I was seeing in the last canary.

Unpack the current magisk_patched.img for your device using my Android Image Kitchen (AIK) project, then create:

ramdisk/overlay.d/init.resetmagisk.rc:

on post-fs-data
exec u:r:magisk:s0 root root -- /sbin/init.resetmagisk.sh

ramdisk/overlay.d/sbin/init.resetmagisk.sh:

#!/system/bin/sh
rm -rf /data/adb/* && reboot

So, pretty simple stuff, and I'm sure it could be applied to some sort of Core Only workaround until [MENTION=4470081]topjohnwu[/MENTION] decides what he wants to do with all those Core Only boot.img Pull Requests. :cowboy:
[Google Pixel 3a XL Guides, News, & Discussion] Tulsadiver:
Cool. What I did was modify the magisk native/jini/core/bootstages.cpp

Edit: yes sir, your method works great to remove magisk and all modules. The method I had gives you the option to just remove the offending module, though sometimes you have to remove everything anyway. Thank you for your awsome input. If it is okay with you, I'd like to offer both methods in my posts on the pixel forums.
