Idk if im just dumb and doesnt know how to search but i cant find the TWRP for the A145M or F, i have fastbootd-recovery.tar and twrp-a145-v3.tar but they dont do anything, fastbootd flashes, reboots and goes back to default recovery, the twrp one just crashes and goes back to download mode
[General Topics] physwizz:
Yeah.

I built twrp for a145f but it doesn't boot.

I thought patched-recovery would work

[General Topics] moais:
hey, its been forever since i flashed anything, i have a a145m and a a146u.

first a thanks, physwizz, for your work and help.

the a145m unlocked and rooted fine with magisk patching, sadly i see there is no twrp.

the a146u i flashed a full XAC_A146WVLU4BWI2 firmware with odin3 v3.14 (not patched) and it passed ok, its running as a a146w now , ive played with the date/time a bit but the oem unlock is still missing in dev options. i just flashed it so hopefully it eventually shows up. the only other issue is speedtestnet is showing a rather slow connection.
[General Topics] physwizz:
You might need to download the latest a146w firmware

Also try the patched recovery for fastbootd on a145m
[General Topics] moais:
it looks like im on the lastest a146w firmware. i played around with the dates and date/update options and rebooted quite a bit and even re-flashed the firmware. unfortunately the oem unlock option still isnt showing up. the slower speed i noticed was because its only connecting lte not 5g. so that explains that. this is just an extra phone i can play with anyway.

with the 145m, i forked your git and patched my stock recovery as instructed. odin said it "passed". but i saw no change. i realized recovery was being overwritten on reboot and had to de-select auto-reboot in odin then *immediately* get to the recovery mode by the buttons.... oh, and i suck at getting into recovery mode by buttons, lol . i did notice it working once but it was overwritten again after reboot. this phone i actually use so i have to back it up before i screw around anymore with it.
[General Topics] physwizz:

Does this work for samsung galaxy a14 SM-A146B/DS?? AND CAN U EXPLAIN HOW TO ROOT ??
[General Topics] physwizz:
Yes it is for your device.

Root Method

​

INSTALL AT YOUR OWN RISK

I AM NOT RESPONSIBLE FOR ANY BRICKED PHONES

But I will help any well-mannered person to recover.

Note: physwizz kernels work best with debloated stock or with wizzROM

Other custom ROMs may not be supported

A. Preparation

1. Root the phone

2. Compress your patched boot.img to make boot.tar

3. Copy boot.tar to PC

Note: If you have previously installed a custom dtbo, you may need to flash stock dtbo

Dtbo installer Extract stock dtbo.img from your firmware. Add to the zip using zarchiver. Use stock dtbo.img from your baseband (not your kernel or your ROM)

t.me

B. Installation

Method 1

Install from twrp

Reboot to recovery

Backup boot and dtbo (if available)

Install kernel zip or boot.img

Wipe both caches

Reboot

Method 2

Install kernel from terminal.

1. Download magisk module (magic flash zip) https://github.com/Magisk-Modules-Alt-Repo/magic-flash

2. Install module and reboot.

3. Open terminal.

4. Navigate to folder containing kernel zip.

Use

ls to list contents

and

cd to change directories

5. Type su

6. Type flash kernel zip

7. Reboot

Method 3

Using ADB

Install adb tools on pc

Connect to PC

Copy zip file to adb folder on pc

Open terminal on pc

Navigate to adb folder

Type

adb sideload filename.zip

Method 4

Using boot.img

Install AIK Mobile from magisk modules https://t.me/physwizz2/82

Use rootexplorer to access

/data/local/AIK-MOBILE

Add patched boot.img and tap unpackimg.sh

Exit the folder and return to see the files.

Edit the files (eg to add a new Image

rename Image to boot.img-zImage and insert in split-image folder)

Tap repackimg.sh

Rename new_image.img to boot.img

Compress boot.img to boot.tar

Copy boot.tar to PC

Reboot phone to download mode

Install boot.tar from odin

C. Removal

Method 1

Reboot to recovery

Restore boot and dtbo

Reboot

Method 2.

Reboot phone to download mode

Install patched boot.tar or patched-ap.tar from odin

@physwizz
[General Topics] skydevil4fly:
Thank you sir👍
[General Topics] gnufirmlink067:
Yes

1. Reboot download mode.

2. Flash AP, BP and CSC

3. Reboot stock recovery factory reset.

Fixed

If you don't have your devices firmware/AP,BP,CSC find baseband information starts with your devices model e.g A145PXXUI734

You should be able to find this info in stock recovery then goto samfw.com and install firmware then repeat from step 1.

Dear sirs, good day

I have a phone A146M 5g Exynos 1330 (a14x), same model of this A146B-A146M-twrp-build3.zip. But I don't know what to flash to it. My phone is already rooted by Magisk but in many tutorials they instructed to do these steps below:

1. Patch the vbmeta.tar file and load it as AP in Odin and flash it. After it’s done, reboot your phone to download mode.

2. Next, flash the TWRP.tar file as AP via Odin. After the flashing is successful, immediately reboot to recovery mode by pressing the Volume Up and Power key buttons simultaneously until you see the “Boot Warning” screen then press power key to enter TWRP recovery mode.

3. Flash the Disable Dm Verity Force Encrypt.

4. Go to Wipe > Format data.

5. Reboot to System or flash any additional modifications you desire.

Do I need to do all these steps when my phone is already rooted ?

I am afraid to flash vbmeta.tar and Disable_Dm-Verity_ForceEncrypt.zip, both files was downloaded from A14 5G tutorial, it do not specify compatible models. Do not know if it is 146P family (a14xm) or if it is for mine 146M exynos (a14x).

Could anyone help me? Just want to flash TWRP.

Hi @physwizz

I still in doubt about the process.

My Rom was rooted using the full ap file patched Magisk.

I need to unroot and flash back stock rom?

Is there any twrp package with recovery.img, boot.img and vbmeta.img I can just flash?

Do you have a link for:

samsung multidisabler zip

and dmverity zip

?

On Download Mode it shows:

FAP LOCK: OFF

OEM LOCK: OFF (0)

[General Topics] physwizz:
It appears you have been trying to follow some old methods.

Just make sure you follow my process.

Dmverity zip is only for older phones without dynamic partitions.

Just follow method 1

If multidisabler doesn't work try this method.

1. Copy /vendor/etc/fstab.**** over to another folder.

2. Edit it to remove the line containing the word "encryption"

3. Boot into twrp

4. Use twrp file manager to replace the fstab file with the edited one.

5. Format data (not just wipe)

6. Reboot to recovery

7. Reboot to system

8. Setup the phone completely

9. Reboot to twrp

10. Backup boot data and super

Hi friend

I am not in this step yet. I just made root using the full ap file patched Magisk.

Just extracted:

AP_A146MUBS2BWJ1_A146MUBS2BWJ1_MQB71982546_REV00_user_low_ship_MULTI_CERT_meta_OS13.tar

From:

SM-A146M_1_20231017050740_660fg4nupd_fac.zip

Patched this 5.77GB AP tar file with Magisk resulting:

AP_magisk_patched-26400_2hTYc.tar (4.83GB)

Inside AP_magisk_patched-26400_2hTYc.tar there are files:

meta-data (dir)

boot.img

dtbo.img.lz4

init_boot.img

misc.bin.lz4

recovery.img.lz4

super.img.lz4

vbmeta.img

vbmeta_system.img.lz4

vendor_boot.img.lz4

... Missing only userdata.img.lz4 if compared with Original AP file

New boot.img and vbmeta.img are not lz4 as original AP tar file, maybe lz4 compression is not necessary.

Flashed this (using Odin):

AP_magisk_patched-26400_2hTYc.tar

BL_A146MUBS2BWJ1_A146MUBS2BWJ1_MQB71982546_REV00_user_low_ship_MULTI_CERT.tar.md5

CP_A146MUBU2BWI4_CP25096896_QB71771651_REV00_user_low_ship_MULTI_CERT.tar.md5

CSC_OWO_A146MOWO2BWI4_MQB71603853_REV00_user_low_ship_MULTI_CERT.tar.md5

User data was not flashed:

HOME_CSC_OWO_A146MOWO2BWI4_MQB71603853_REV00_user_low_ship_MULTI_CERT.tar.md5

After this root process I tryed to flash your A146B-A146M-twrp-build3.tar and it doesn't work, recovery falls to download mode with this information:

"Recovery: Error while checking public key used to sign data. (2)"

"Custom recovery"

"VBMETA A146MUBS2BWJ1, 71982546R"

then I flash back stock recovery.img.tar

Is this vbmeta a encryption key?

That works like a charm

Next step is to flash GSI image. I am trying wipe data and dalvik cache for now but TWRP is giving me failed messages:

To unencrypt

Method 1.

1. Connect to pc and boot into stock recovery

2. Factory reset

3. Reboot into download mode.

4. flash twrp tar file from Odin into the ap slot

5. reboot to recovery

6. Advanced, terminal. Type multidisabler (twice).

7.

Or flash samsung multidisabler zip

Or, for older phones flash dmverity zip

Note : Multidisabler will not work on some phones so you should decrypt manually

8. Reboot to recovery from main menu (not just reboot)

9. Reboot to system

Hi

@physwizz

I tried this method but there is no file " /vendor/etc/fstab* ". This /vendor/etc have only selinux and other generic xml file. I found fstab only on /etc, and it is a common fstab with no " encryption " parameter.

Multidisabler and dmverity do not works, receive the same message about failing mounting /data.

May I can format /data and try to flash a new rom, it is risk trying, if it do not works may I can brick the phone.

May in near future developers could make one safe method for flash new roms on A146M.

Thank you very much for support and

FRP is google account.

How to Easily Bypass Samsung FRP with UnlockGo

www.xda-developers.com

It depends on which version of Android you're using. If your phone is stolen, it may be locked in one country and work in another country, I don't think FRP would be blocked by the operator. but If it is, then there is a reason for it. It's an old tutorial and I don't know if it works, most of these tutorials don't work. I don't know if it would be worth doing an unlock device that costs a few bucks
[General Topics] mladen81:
No. Phone is bought in a regular store with regular warranty issued. Everything is completely regular. Android version is 13. One UI version is 5.1

When I change CSC code for a short time through SamFw tool it is possible to register phone onto the network and to make calls. After few minutes connection is lost.
[General Topics] Walterkom:
why Did you change CSC code? I understand that FRP is a Google Account lock. It doesn't matter where the phone was bought, there was just a Google account, but there are phones that are blocked because there was something unpaid or someone stole them, typically, it is a phone that is not paid, that's why you can't make calls from them. If I buy a Samsung in America, will it work in Europe, was that the question? if you can't flash with Odin, you could have broken that phone. You can ask your carrier why your phone is blocked. unless you have uploaded the wrong firmware. Maybe it's just a demo. Maybe it's a question for you, where did you buy that phone and what did you do with it. If you buy a demo from eBay, you won't be able to call. Maybe it's a hardware issue, if you don't know the history of the device, it's hard to give specific advice. For example, if I make a mistake in Odin, I can completely break the phone. That's why it's so important to back up your original software. You will correct your own mistakes, but it will be very difficult to find the mistakes of others, for that you need a lot of knowledge
[General Topics] mladen81:
Did you read all my posts? Phone is bought regularly with invoice. It can't be stolen. It is few months old and for all of this period it was not possible to use it except in Germany and Croatia. I am trying different solutions. It is not expensive and I want to try to solve this by myself. I am not an expert but I will continue to try until I repair it or until I brick it. If you have any good ideas they are welcome. Why am I change CSC code? Because I figure that it has some connection with localization of the system for some countries or regions. Also I unlock bootloader. Idea was to install twrp and custom rom and hope that it will solve the issue but as I can see there is no completely working twrp and also no custom ROM for this phone.
[General Topics] Walterkom:
Samsung typically sells an EU distribution that can be used in Europe. why is it blocked in Germany and Croatia and is it blocked by who Samsung? or operator? what is the distribution? check your imei. https://www.imei.info/samsung-imei-check/

[General Topics] mladen81:
"why is it blocked in Germany and Croatia and is it blocked by who Samsung? or operator?" I don't know is it blocked or not? Maybe it is hardware problem. I'm just guessing. Phone is bought, we can't use it. That is the fact. I am trying to fix through the software. If it is not possible than problem can be with hardware and I will drop it and that's it. I was able once to solve similar problem with my old Huawei Y6 using your forum. But than things were not so complicated as now.

At this situation my idea is to format everything in the phone. Complete system and data and to install completely new system. I thought that custom ROM would be the best solution, but if there is a way to format everything without things that you called TWRP, maybe official ROM will work as it should be. I have checked IMEI and status is CLEAN.
