you should be blessed, thanks

I went and downloaded the EUX region A13 firmware and replaced the two necessary images. I assume it's the same bootloader for all regions but be ready to rollback to the default bootloader via ODIN if you end up having bootloops after flashing. Let me know if it works.

It works, I'm on eur A13 firmware

Confirmed it also works for the new VL7 firmware and its bootloader. Nothing changed inside up_param so it makes sense.

If you follow this guide it will cause your table to bootloop on an SM-T220 running the latest firmware T220XXU1CVL7_T220OXM1CVL7_XAR
Can you please put a warning in the instructions? Thx

SM-T220 running the latest firmware T220XXU1CVL7_T220OXM1CVL7_XAR

Post #24 right in this page for your Android version.

Ty! Worked on T227UVLU3CVLA on android 13 too!

Hey I tried this, even using the .tar from post #24 and it just does nothing i get a permission denied error when i enter the code via termux?

SM-220 on build number T220XXU1CVL7

If I try doing it via shell it says the following:

d/up_param.tar of=/dev/block/platform/bootdevice/by-name/up_param <

dd: /dev/block/platform/bootdevice/by-name/up_param: Permission denied

0+0 records in

0+0 records out

0 bytes (0 B) copied, 0.002078 s, 0 B/s

Only remove yellow/red warning text but not 5 minutes delay, How to remove delay time to boot?

5 minute delay? That's crazy.
My Motorola in "orange" waits 10 seconds.
I have another device that I often reboot that used to do 30 seconds.
I modified abl on that to skip the wait.
But that device had SecureBoot off, a rare luxury.

I don't see the su command before the rest as mentioned in Step #3 in the original post.

I just wanted to let you know the file from post 24 works perfect on mine,
using firmware SM-T220_EUX_T220XXS2CWA6

I didn't use termux by the way, just used ADB.

Commands (from windows);

adb shell
su (you should get warning from Magisk, accept)
cd /
dd if=/storage/emulated/0/Download/up_param.tar of=/dev/block/platform/bootdevice/by-name/up_param

Hi, I'm seeking deletion of warning msg on rooted TAB A 8.0 LTE ( SM-T295 ) with TWRP/Magisk on the device.

Would the SAME up_param.tar file work on my device or am I in dangerous territory assuming that?

Can anyone steer me to achieve the same warning deletion on an SM-T295?
Thx

Wrong device forum.

No. If you try, you're on your own.

No. If you try, you're on your own.

Thanks for the heads up. Any chance to steer me on how to get a valid SM-T295 up_param.tar file created ?

You need to ask that question in the appropriate forum for your device.

I don't think you will get answer in other forum, as that method is not really common. I personally don't think it is even removed, but the OP in this thread may explain what is the magic in that file regardless of the device model (OP is explicitly stating it is allowed to ask for other models)

the only explanation I found does not disable the timeout, it only mask the warning.

Yup, you're right about that. It only masks the warnings by replacing certain image files to make the boot screens a bit more visually pleasing. I redirected the user to his device forum because flashing bootloader files is a sensitive thing that can cause bootloops.

It's trivial to patch the abl to get around this.
OTOH, for 99% of all devices you can't patch abl and still have it work.
Fortunately I have a 1% device and I patched the abl to bypass a 30 second delay on booting because of "orange state".
