Samsung Lockscreen Denies My Password

Samsung Lockscreen Denies My Password

eromatiya opened this issue 5 years ago · comments

I patched boot.img and flashed it using odin. After successfully rooting my device, I can't login to my samsung account and the lockscreen denies my pattern/pin. After rebooting, the device bootloops. My device is SM-J810F Pie and I used Magisk Canary 19.4. Please. fix it. Thanks in advanced!

Logcat would be most helpful

Find magisk log catcher module, flash in TWRP, boot and capture the issue z than reboot to TWRPA and pull the logs from /data/local/boot

Sorry, but there's no TWRP available for my device that's why I just patched the AP/boot image and then flashed it using odin.

I think I have the same issue with them:
#1696
#1617
#1682

Sorry I couldnt be more help.

Update:
I tried to root again and I followed the instruction in install.md. I start the adb logcat, set the pattern, locked my screen, and then tried to unlock it. Of course, the pattern is not working.

Here's the logcat:
logcat.txt

There's an interesting line:
08-29 12:27:48.641 1153 2849 E LockSettingsStorage: Cannot read file java.io.FileNotFoundException: /data/system/fmmpassword.key: open failed: ENOENT (No such file or directory)

I think the pattern I set doesn't save that's why it's not working on lockscreen. Also, I still can't login to my samsung account. Always "Processing failed." Sorry for my bad english. Thank you in advance!

Do you use Android 9? Because since Android 9 I need to use a custom kernel for my s9 and before I hade the exact same problem

eromatiya · Answer 5 · Wed Sep 04 2019 10:49:31 GMT+0800 (China Standard Time)

Yeah I think there is a compatibility issue with magisk and my device's custom kernel. Sadly, there's no custom kernel for my device. I'll stick around with custom rom for now. Hopefully they can fix it in the near future. Yes, I'm on android pie btw

Unfortunately I cannot fix weird Samsung kernel issues without the device on my hand. S10 is directly supported because I had the device on hand, I know what files I need to patch to make it work properly.

Well this falls back to software AOSP keymaster instead of using hardware keymaster, that's not as fix, more of a workaround. Le jeu. 12 déc. 2019 à 14:11, Mohamed Omar <notifications@github.com> a écrit :

yes ,

if u have twrp use it as it will be easier .

mount vendor

then use terminal and write command .

if u on system.

su

mount vendor as rw :
mount -o rw,remount /vendor
if u are sar and u faced problem with mount point :
mount -o rw,remount /

then command .

don't reboot until u see ------ before 1 root .
command to check :

ls -l /vendor/lib/hw/ |grep keystore

=================

then reboot .
try lockscreen .

Sadly, the workaround didn't work for me @Kopra159 . I still can't login to my samsung account and the lockscreen is still broken. Btw, I use adb to change the permission after rooting and I don't have the keystore.msm8937.so in my /vendor/lib/hw/

eromatiya · Answer 25 · Sat Dec 14 2019 16:18:04 GMT+0800 (China Standard Time)

Nope, I just flash a stock rom then root it. After changing the permission using su -c 'chmod 0 /vendor/lib/hw/keystore.*.so' in adb shell, I reboot my device. On start-up, it requires me to enter a password but I never set any password or pattern.

give me result of check command

Okay, I'll try it

The fix temp was flashed successfully. After rebooting, the same problem on start up: Your phone is encrypted for security. To start up your device, enter your password. Again, I didn't add any password or pattern.

ok , in twrp , try manually

rm -f /data/system/locksettings.db
rm -f /data/system/*.key

then reboot and see if password is there ...
and tell me.

also send pictures about lock if it will be there , maybe it is relate to payment service or others .

Tried

chmod 0 /vendor/lib/hw/keystore.*.so
rm -f /data/system/locksettings.db
rm -f /data/system/*.key

as root on my Tab A 10.5.

The chmod definitely worked; I had to mount -o rw,remount /vendor and try again, then 'ls' showed the permissions changed to '------'

Likewise, 'ls' showed the locksettings.db and *.key files were gone.

Rebooted, and now I have a friendly

Your tablet is encrypted for security.
To start up your device, enter your password.

Neither of those things are true, i.e. the device is not encrypted (and the reboot was waaay too fast for it to have applied encryption at that point), never has been, and no password has ever been set (I did the above shenanigans so I could (hopefully) set a password.
