I got secure check fail : vbmeta.img error on t297. What's the problem? What should i do to patch mine?

I mean what's the purpose of patching vbmeta?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gcrutchr:
vbmeta.img is a secure check against installing non-Samsung software. You need to disable it to install TWRP. Ignore error as long as TWRP installs.

You are on bootloader v4. You cannot root device. Also, you cannot go down to V3.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Yxles:
how do you know what version of bootloader you have?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gcrutchr:
Ex: T295CZCU4CUK5....5th character from right = 4 = v4 bootloader
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Yxles:
So my Baseband version is T295XXU4CUK4 meaning I have a V4 Bootloader?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gcrutchr:

Sh...

I was nervous.

I've flashed the AP of step 4 of the instructions.

Then Odin and the Download Mode started hanging.

Nothing went in.

I've rebooted the Tab by pushing the Per and the Vol +.

Now this : ...

Is there anything, I can do, wright now?

I hardly can't power it off.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] JonnyBoy1984:
Here I am again.

Suddenly it was so easy.

I've tried so much options, but I rember, I hope this has been the truth,:

I've cabled in the phone.

I've pushed Vol+ and Vol- together.

And than I've pushed the Pwr-button.

Than there comes the questions and options:

1) if unlock, push "long press" Vol up

2) if you wanna load the bootloader, push Vol+

3) if cancel push Vol-

It's been something like this.

Next try,

To the Instructions:

1. I´ve got the SM-T295 with Android 11 on it. I've just today freshed the firmware up, with Odin and Frija. Should I also flash BL 9, like you have written?

Can somebody who did it right and it worked help by "From the pushing of the first Key 'til the loaded TWRP ?

It hardly doesn't work, by me.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gcrutchr:
Check your bootloader version. If it is 4, you cannot install TWRP, and you cannot downgrade bootloader.

Ex: SM-T295CZCU4CVF2

The bold number is the bootloader version
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] JonnyBoy1984:
Yes, I've finally flashed it to 4, I didn't knew it before .

It's annoying for Samsung to do this. Why won't they just let us downgrade?! I've been trying this for days for nothing. Thanks, Samsung.

Edit: Is there no way to change the version number in the code and make it think that it's upgrading but it's actually downgrading?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gcrutchr:
The downgrade block is in the bootloader

Hi guys

I wanted to install TWRP on my sm-t295. I got to the point where after Odin I went to step 8. When the phone rebooted I got the yellow exclamation mark and the text I am not running official samsung software.

Then I got a red text at the top that security check failed on boot.img

at the bottom it ways: security error, this phone has been flashed with unauthorised software....

After the first time I saw the security error screen, I dont see it any more, only the first yellow exclaimation mark screen.

I can not get to TWRP

Otherwise the tablet boots in android. It is android 11. Firmware T295XXU4CUF7

What did I do wrong

Hi,

Does someone tried to restore the system with the 3.4 version of TWRP ?

I tried to do so, but what was my surprise, when it was not able to reboot after restore was complete. I had to reinstall all, restarting from scratch and now, I didn't reinstall TWRP, as I am no longer confident in it.

Do I have to use another version ?

If you could help me... thank you.

[General Questions and Answers] thardy00:
Hi!

It's been a while since I was Anroid OG but I remember that in the past when I was using Xperia X I had an adblock which was blocking whole ads (I've got this phone to this day and it's still blocks most of ads even without changing anything since years). I didn't see a single ad at that time, but that was couple of years ago and many things changed. As I figured out from my research there are many different ways to block ads right now like VPN/host/DNS.

I would like to know what is the best way to block most ads without big impact on battery life right now (I've read somewhere that some methods have bigger or smaller battery drain but it's definitly there). I'm a user of OnePlus 7T (no root, but I can root it if it would help).

Also I see that when You have root You need to hide it from some apps because banking apps might not work for e.g.. Hence my question do root makes your battery life worse since You need to hide it, etc.?

Regards, Dan.
[General Questions and Answers] :
If a device's Android is rooted then in background runs the service named "daemonsu" what as any other running process drains the battery.
[General Questions and Answers] XDHx86:
Honestly this is a first, and I saw a lot of questions about root.

No, root doesn't affect battery in any way. But in contrary it is used to save battery life.

Here are some ways you can block ads with:

​

No root:

​

You can get VPN, simple with bonus security although not efficient imo

Configure DNS, you'll need specific list to do that and a lot of time

Modify apps to remove ads, modifying apps can lead to breaking them and you have to uninstall the original app. But it works perfectly

​

With root:

​

Patch apps ODEX file to remove ads, since you can't uninstall system apps

Edit hosts file, simple, efficient and works generally

Block google services ads activity by modifying/patching it, works on google ads only

Installing adblock module with through magisk/xposed, this one works best imo and saves time and effort

As for what works best, I myself use hosts file, modified google services and most apps I use are patched. And I didn't see any ads since I got the device. And as you can see, root works better and more efficient.

Though modified google services might be an overkill.
[General Questions and Answers] thardy00:
@XDHx86 I see You are pro :D. So basiclly for noob like me rooting and installing adblock module through Magisk + Adaway adblock (rooted version which works via host files) would be more than enough?

Could You please provide some links to guides/reading about installing adblock module through Magisk or editing host file?

Also could You please share some tips how can noob like me increase battery life through having root?

Thanks for sharing Your knowledge @jwoegerbauer @XDHx86
[General Questions and Answers] XDHx86:
For the magisk module you just open magisk manager and install the module from there.

For the hosts file:

Install ublock extension on Chrome/Mozilla.

Open the multipurpose section in ublock settings and preview "MPVS HOSTS" and "Dan Pollock’s hosts file"

Copy what you see in a file and save it.

Send the file to your android and save it in "/system/etc" and the name is "hosts" without extension.

Alternatively you can try using adb to push the hosts file:

Command: adb push /system/etc/hosts D:\Files\hosts.txt

Note: Replace D:\files\hosts.txt with your file location. On some devices this may work without root.

For battery life I just use greenify app with root. There are definitely better options out there but I don't really care.

Hi everyone ,

i have recently flashed Lineage os 17 on my z2 only to find out i can't detect any wifi networks.

i did some search and it looks like it is a wifi region code problem and it seems like it is not going to be solved soon (correct if i am wrong as i found out it goes back to 2019) so basically nothing is really working after android 7.

so guys if yo know any Rom that provides this i would appreciate suggestions.

and if not please do recommend old roms with good battery performence .

ps : there is one method i haven't tried because i was not sure if it would harm my device.

Reverse all actions
