Development [RECOVERY] [OFFICIAL] TWRP 3.5.2 for Galaxy A52 4G

[Deleted member 11588103]

There is a official twrp for this device on the team win page now. They give clear instructions on how to install. One thing they point out is, to root first and then install twrp. Read the instructions, they explain a lot.

Ok so I read the official TWRP page - https://twrp.me/samsung/samsunggalaxya52q.html

But there is one thing I am a bit confused by, the instruction page tells us that we need to install magisk in the recovery (TWRP) so does that mean after downloading the TWRP file I should patch it using the magisk app and then flash it.

Last question will flashing TWRP wipe the device? (Im guessing it wont but it is recommended that I format the data)

I flashed twrp and disable_dm_verify but now my phone only boots into twrp. Tried factory reset in twrp but this doessn't work.

You need to download the firmware for your phone using a tool like Frija and then simply boot your phone into download mode and flash the files using Odin.

Download original FW of your version and flash whole AP part with Odin. Or extract original boot and dtbo images from the AP.......tar archive, copy them to the SD card, boot to TWRP and flash them using ADB commands of type: dd if=/external-sd/boot.img of=/dev/block/by-name/boot

I don't understand Frija

flash them using ADB commands of type: dd if=/external-sd/boot.img of=/dev/block/by-name/boot

can't flash it using twrp terminal (right?). I renamed the file to boot.img and dtbo.img but the files are on the internal sd.
Please Help.

I renamed the files to .img and made an .tar-file. How can I flash it using TWRP or ADB?

Ok so I read the official TWRP page - https://twrp.me/samsung/samsunggalaxya52q.html

But there is one thing I am a bit confused by, the instruction page tells us that we need to install magisk in the recovery (TWRP) so does that mean after downloading the TWRP file I should patch it using the magisk app and then flash it.

After reading the official TWRP page I understand that I have to patch TWRP file using magisk.

But what confuses me is:
[...] If you intend to root your (a52q) device, be advised that Magisk will be installed to the recovery partition, not the usual boot partition. Both TWRP and Magisk-rooted Android boot using the recovery kernel, with the device's hardware keys used to choose between TWRP and Android at boot time.
You are therefore strongly advised to first root your device with Magisk and then pre-root a TWRP image before flashing it to recovery.[...]

So I follow the link to root my A52 first with Magisk and read carefully that
[...] If your device does NOT have boot ramdisk, make sure “Recovery Mode” is checked in options.
In most cases it should already be automatically checked. [...]
But: after installing Magisk V23 apk from official site here it states "Ramdisk: YES" and I do not find any option "Recovery Mode". So I assume that Magisk is patched into boot partition and not into recovery mode partition when I press "install".

So from my point of view there is a contradiction between

• If you intend to root your (a52q) device, be advised that Magisk will be installed to the recovery partition

and the fact that according to Magisk apk a ramdisk exists, i.e. magisk will be installed to the boot partition. Also in the video in the very first post of this thread it seems that after rooting (starting from minute 6:16) the device boots up normally (not via recovery) and has root enabled.

@RealVelosh: Can you help to solve the contradiction?

You can not flash samsung firmware like that, on a normal android phone (like a pixel for eg) you can use ADB/Fastboot but samsung phones do not have a fastboot mode. Instead it is replaced with "download mode" which requires the use of ODIN.

You can install new software using TWRP but if you are trying to reset to the factory state use ODIN.

Also I saw that you said Frija didnt not work for you or you were not sure how to use it so here is another tool you can try

Simply open the program and type the model number of your phone (it should be SM-A525M or SM-A525F) and also give the region code. Then once you have done that it will download the firmware.

Yeh because as it is right now, I am using my A52 with root (but no TWRP) and there is no need for me to boot into the recovery in order to get root. And I am also not seeing the option to patch the recovery, if it try patching twrp in magisk it says "Patching boot image file".

So I am just as lost as you.

Hello weazl, how are you? The way of installing Magisk from TeamWin Docs is a prebuilt and common way for all Samsung devices, discard this installation form (TeamWin/Magisk Docs) for A52/A72. You can reproduce the Magisk installation like this:
1 - Install TWRP
2 - Format data, flash multidisabler & dm-verity disaber then reboot to recovery
3 - Flash Magisk, format cache/dalvik/data/internal storage.
4 - Reboot to System

 

[RealVelosh]

You can install without TWRP, but if you want with TWRP, it's a little more complicated.

 

[weazl]

Thank you for your quick reply, I highly appreciate your awesome work!

discard this installation form (TeamWin/Magisk Docs) for A52/A72.

I think this is the most important information for anyone following this thread! Glad you clarified that for us!

You can install without TWRP, but if you want with TWRP, it's a little more complicated.

Two more questions still open for me:
1. So if I aldready have Magisk installed (in boot and not in recovery) without TWRP, then it does not matter if I

• install TWRP using App Install Method

or

• install TWRP using Odin Install Method

right?

2. Is it then still necessary to Format data and flash multidisabler & dm-verity disabler?
