I just installed the custom kernel and every time I reboot I get a warning, another thing the multidisabler doesn't work, I took screenshots in TWRP but they aren't saved anywhere, and the partitions are only in read mode and I can't modify them, I mean I try delete an app from the system and it doesn't work. Another thing, do you know how to fix a warning from the operator that I get to restart all the time, that only happens when I root the device?

image 1: Notice that appears after installing the custom kernel

Image 2: If the custom kernel was installed

Image 3: Notice that appears all the time when I root with any version of magisk
[General Topics] SibenVN:
It works, but when I put the sim in, it doesn't recognize the sim, and it has signal but has an x mark and can't make calls.
[General Topics] physwizz:
The Android system message is normal for custom kernel.

The gsi is responsible for your sim card issue. It is related to your service provider.
[General Topics] physwizz:
That is your service provider.

It only works with stock, not GSIs
[General Topics] JsJhonatanJs:
I understand, do you know how to make the partitions not read-only or can't it?
[General Topics] physwizz:
To mount system as rw

1. Boot into recovery

2. Go to terminal

3. Type

mount -o rw,remount/system

Or

mount -o rw,remount/system_root
[General Topics] JsJhonatanJs:
It doesn't work, the TWRP screenshots are not saved, otherwise it will send you screenshots

Convert /system Partition From R/O To R/W

MAKE SURE you read the developer's installation specifications here

- Copy the RO2RW.zip file to SDCard.

- Boot into Download Mode, open Odin3 and flash AP, BL, CP, CSC or HOME_CSC

Note: AP patched by Magisk (or Magisk Delta)

- Once done, reboot into "Stock Recovery" (Power + Vol Up) and "Factory Reset".

- Then reboot into Download Mode and flash TWRP using Odin3.

- Next, boot into TWRP, go to "Mount" and mount everything.

- Flash RO2RW.zip from SDCard

- Then carefully follow the instructions in the script.. adjust your preferences...

- Download File Explorer and give it root permissions and check /system folder has RW permission or not.

Good luck, hope it works for you.

USEFUL INFORMATION:

- This will help TWRP work as usual, most functions will work normally: Install, Mount, Backup,...

- It will also fix "Data (0mb)" and "Internal Storage (0mb)", ...

To @physwizz,

The patched magisk were working just fine, but Samsung

added more updates

to the device and seems to have

broke the application

. Several attempt had been carried out on patching the latest official ROM for Samsung Galaxy A13 specifically

A135F

and it doesn't seems to have the capability to patch the ROM anymore.

An owner of this device made a thread on this platform, laying out steps he found to be working with the official magisk version 26.3. His steps works fine, but Bluetooth won't remember connected devices after a clean reboot. Making do with it is OK, but it

does raise concern

on what feature aren't available after patches.

As you've more experience on the device compared to other average user, an update of the application with your

golden touches

are very welcomed.

Thank you for reading.
[General Topics] physwizz:
Thanks for your vote of confidence but I can't modify magisk.

As far as I know 26.3 seems to be the best.

The other options for root are Apatch or KernelSU

Users on other forums (telegram) might help with Bluetooth issues

This is why I haven't upgraded my A127f from Android 11.

I have avoided Samsung's "improvements "

Can you share the twrp installation and necessary files for the a137f model?

Thank you for the twrp file you sent.

I would appreciate it if you explain it like you would to a novice user.

I am currently using stock firmware. After learning the magisk and twrp installation stages, I want to take the necessary actions.

There are twrp and magisk installation videos for 125f on Youtube, 135f twrp and magisk installation articles on forum sites.

one is installing vbmeta, the other is installing patched AP.

I'm so confused so far I couldn't find the twrp file anywhere so I didn't root the phone so I'm just gathering information until I'm sure what to do.

I'm in no rush, I can be patient until I find out.
[General Topics] girello:
Hi,

Thanks for these. I have a A137f here.

I tried both images but the phone seems to be stuck in a boot loop now.

What I did:

- unlock bootloader

- put phone in download mode and use heimdall to flash the recovery partition with the above image(s)

Outcome:

1) Phone reboots

2) shows message about unlocked bootloader but doesn't respond to power key to continue

3) hangs there for a while, then reboots and gets stuck at 2)

I can enter download mode again while it reboots and reflash, no problem.

Any hints how to get twrp onto this device would be much appreciated :)

Also, any hint how to get back to stock recovery to get the phone to boot properly would be nice :)
[General Topics] physwizz:
Installing Custom Recoveries

A. Preparation.

1. Download firmware for yourl device

2. Extract ap file using Zarchiver

3. Patch the ap file with a magisk which will patch both boot.img and vbmeta.img

For Exynos 850 android 11 use a21s patched magisk.

For Exynos 850 android 12 and most other devices use delta magisk

4. Unlock OEM in developer options

5. Attach phone to pc and reboot to download mode

6. flash patched ap file.

7. Download recovery.img or download twrp.tar and extract recovery.img using Zarchiver.

B.Installation

Method 1.

1. Connect to pc and boot into stock recovery

2. Factory reset

3. Reboot into download mode.

4. flash twrp.tar into the ap slot

5. reboot to recovery.

6. Advanced, terminal.

7. Type multidisabler (twice).

Or flash samsung multidisabler zip

Or, for older phones flash dmverity zip

8. Reboot to recovery

Backup boot, data, super and dtbo

9. Reboot to system

Method 2.

If you have already installed recovery and decrypted.

1. Boot to recovery.

2. Install recovery.img

3. Choose recovery partition

4. Reboot to recovery

Backup boot, data, super and dtbo

(For Pitch-black just install the zip)

Method 3.

1. Install TWRP app

2. Install TWRP

3. Choose file to flash.(don't select device)

4. Select recovery.img.

5. Reboot to recovery.

6. (You may need to change data partition to ext4 first if format ruins your system)

7. Reboot to recovery.

8. Wipe, format data, type YES.

9. Advanced, terminal.

10.Type multidisabler (twice).

Or flash samsung multidisabler zip

Or, for older phones flash dmverity zip

11.Reboot to recovery

12. Flash Magisk for root(only for method 3)

13. Backup boot, data, super and dtbo

C. Recovery Problems

Most recovery issues can be solved by attending to the following issues.

1. Did you root using the full ap file patched Magisk .

(This contains the patched boot.img and vbmeta.img)

Exynos 850 users must use the special a217 magisk?

2. Did you then go all the way through the setup process?

3. Did you download the recovery to match your baseband?

See https://t.me/a127f_res/54 for Exynos 850 recoveries

4. Did you hold down power and volume up after Odin says pass?

5. Did you format data, not just wipe?

6. Did you type multidisabler twice?

7. Did you reboot to recovery by choosing reboot from the menu and then choosing recovery?

8. To avoid touch issues go to settings and untick "allow time out"

D.To restore Stock Recovery

1. Attach phone to pc and reboot to download mode

2. flash patched ap file.

3. reboot

Anyone able to install twrp on a137f?

What is the latest status of girlello?

were you able to install twrp?
[General Topics] girello:
I think I bricked that phone somehow now. I was able to recover once from the boot loop I mentioned above by flashing recovery.img from the original firmware package.

This didn't work a second time. When trying to reflash more of the original firmware this resulted in an incomplete flash. Since then the phone shows "An error has occurred while updating the device software".

I can activate download mode, but the device doesn't seem to respond to commands from heimdall. It only reports:

Initialising protocol...

ERROR: Failed to receive handshake response. Result: -7

ERROR: Protocol initialisation failed!

So far I didn't have any luck with Odin from within VirtualBox. I'll try Odin on a native windows box next. After that I'll run out of ideas.
[General Topics] girello:
Nope, no luck with Odin. It just hangs a long while at "SetupConnection..", then eventually fails with:

All threads completed. (succeed 0 / failed 1)

The device's display doesn't show any activity, just the normal download mode screen without progress bar. I cannot boot it into recovery mode and can neither access it through adb nor fastboot.

Does anyone have any ideas what else to try?
[General Topics] mazlumelarslan:
On my previous phone, my device that went into boot loop, my attempts to return the original firmware via odin were always successful.

Could using the heimdall tool be the reason for failing to load stock firmware via Odin?

because here is the person who has the same problem;

Heimdall is among the tools it uses when getting a stock firmware upload error.
