[Samsung Galaxy S21 Ultra] rodeto:
I updated my Samsung S21 Ultra (G998B) to Android 12 a couple of days ago. After that the default navigation app is set to Google Maps. I tried to figure out how to reset that to Waze but it can not be changed.

Before Android 12 is was just a matter of setting all apps to "not default" and a pop up appeared to ask you what you wanted to use.

But now it seems that you have to fnd the app in Apps and select the option "set as default". You can also choose the links that have to open the app. But when I want to set my default navigation app to Waze things go wrong. For some reason the links do not stay selected and are deselected as soon as I close the window. So there is no way to set the app as default. I already removed Maps but that doesnt help.

I already contacted Waze Support but the only replies I get from them is a simple answer on how to set default apps in Android 11. It seems they do not read questions.

Does anyone know how to resolve this issue?
[Samsung Galaxy S21 Ultra] rodeto:
Thanks for the reply. Nice app!

But it doesn't work when you want something through a browser. At that point is still goes back to Google Maps, either the app itself or Maps on the internet.

[Xiaomi Redmi Note 8 (2021)] FreakyJoost:
Hey everybody.

So I've recently got this Redmi Note 8 (2021) and figured I'd root it.

After the week of waiting to unlock the bootloader, I did the next step to install Magisk.

Due to the lack of custom recovery, I patch the bootimage, and flash it with fastboot.

However after this, the phone is stuck on fastboot, so I guess something is missing.

I also tried the canary versions, but no success yet.

Did anybody succesfully instal Magisk on this phone? Or some other type of root?
[Xiaomi Redmi Note 8 (2021)] FreakyJoost:
I'll just answer my own question here.

Android 11 MIUI devices need enabled verification in boot.img AVBv2 signature​

This pull request will fix it (for me): https://github.com/topjohnwu/Magisk/pull/4975

Trying the vvb alpha worked for me.
[Xiaomi Redmi Note 8 (2021)] pierzale:
You should flash first vbmeta.img with this command:

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Then flash the previously modified boot image with Magisk:

fastboot flash boot boot.img
[Xiaomi Redmi Note 8 (2021)] FreakyJoost:
I heard about this vbmeta at several occasions, but I haven't found a proper resource or download location for it.

How do I create or download a patched vbmeta?

Other than that, the solution I posted does work for rooting my device. But I think flashing vbmeta might open some options up for me like a custom recovery.
[Xiaomi Redmi Note 8 (2021)] michLQ:
Hi.

when ich put that command i became that error:

C:\adb\fastboot.exe: unknown option -- disable-verity

sorry, i made a mistake. got it now
[Xiaomi Redmi Note 8 (2021)] cristianlp:
hello can you help me to root
[Xiaomi Redmi Note 8 (2021)] FreakyJoost:
Sure.

Install the newest magisk.

First unlock the bootloader, then patch a boot image with magisk, and flash it to your boot partition with fastboot.

AFAIK, adaptive charging only happens if these conditions are fullfilled:

An alarm is set before 10 AM

You plug in your phone for charging after 9 PM

So far I have managed to adaptive charge my Pixel the few days I've had it, but yesterday I noticed the adaptive charge wasn't triggered. I had over 40% of battery. Question is, am I missing some condition? Like the phone must be < 40% in order for it to get triggered?

On a side note, would be great if Google lets us configure those settings. Not everybody has the same sleep routines and goes to sleep at night.

On occasion I noticed charging was not adaptive, but taking the phone of the charging and putting it back on started the adaptive cycle.

Thank you very much for your hard work! Do you think the future of this device is gonna be bright in regards to custom ROMs? I'd love running this on LineageOS.
[Miscellaneous Android Development] afortaleza:
If there are LineageOS versions running on devices on the same chipset I think it will be easier to have one for F21 Pro. But the launcher will have to be more adapted to the screen size.

[Miscellaneous Android Development] dj_sash:
Hi and good morning/evening mlgmxyysd,

I just want some clarifications about the result of your crack tool..

What will we be able to do that was not doable before?

1. Can we access the Google Playstore or other Playstore alternative to install any apk on the device?

2. Can we upgrade our Android 11 system, which I think is not possible on the original Q21 Pro? I mean keep it uptodate with little android updates

Would be glad for a clear answer and thanks so much already for you effort ;)
[Miscellaneous Android Development] mlgmxyysd:
Yes, we can, but we need more development. This is just a 🗝 to allow you to do so.
[Miscellaneous Android Development] didgeridoo3678:
Will this also work on F21 Pro+?
[Miscellaneous Android Development] mlgmxyysd:
No, I exploited a hardware vulnerability in F21 Pro (yes, it is similar to iPhone jailbreak, cannot be fixed via OTA). This vulnerability does not exist on F21 Pro+.
[Miscellaneous Android Development] didgeridoo3678:
And is there a significant difference between the 3GB+32GB and 4GB+64GB models? Performance wise?

And is there any (Chinese) spyware on the F21 Pro? Can we delete or disable it?
[Miscellaneous Android Development] mlgmxyysd:
4GB+64GB is 1GB+32GB more than 3GB+32GB
[Miscellaneous Android Development] mlgmxyysd:
If you think it contains it, it has.
[Miscellaneous Android Development] didgeridoo3678:
I know, but is that 1GB difference noticeable or no? I've never had an android phone before, that's why I'm asking.
[Miscellaneous Android Development] didgeridoo3678:
I'm not sure if it does. That's why I asked. I don't have an F21 Pro haha
[Miscellaneous Android Development] mlgmxyysd:
I don't think it will affect much, but 32G is easy to full
[Miscellaneous Android Development] didgeridoo3678:
Will we be able to flash LineageOS or another custom ROM in the future?

Edit: could we btw make some sort of group chat for F21 Pro users/enthusiasts to chat on? Would seem easier to share thoughts and ideas.
[Miscellaneous Android Development] mlgmxyysd:
There is a group chat links inside the software.

Thanks for the unlock tool, works great but i do have to unplug and re-plug after every phase of process. Nevertheless though it works great. I do have a question though, i have the google GSI rom running on here and have had lineage and Dot Os all working on this device(f21 pro). One major issue i can't seem to get yet is how to implement the hardware keyboard to the rom. The touchscreen keyboard works fine and the hardware keyboard recognizes the numbers but no letters.
[Miscellaneous Android Development] sreerajpsin:
Is there a way to relock bootloader after whatever we needed system like gapps ?
[Miscellaneous Android Development] mlgmxyysd:
I'm not sure if the device supports this feature, but you can have a try. If you can't boot after self-signed relock, just use tool to unlock it again.

can't help you with this as thread starter @mlgmxyysd is paranoid and made this php script kinda closed source with base64 encoding, but according to post #6 you can just try the original mtkclient instead (as that's where the error comes from). it should be also possible to restore backup with this.

edit: maybe it requires brom mode, not preloader mode?
[Miscellaneous Android Development] alecxs:
@ykalinga have you done this? it simply means you have to repeat the connection step - it probably just requires intermediate reboot into BROM again

Keep the bootrom key pressed, keep pressing the power key to forcibly restart the device until the computer displays the device connection prompt and releases the power key. The program should automatically execute the next step.

[Miscellaneous Android Development] Biden2020prez:
Excuse me... can someone please explain to me the benefit of this script? On my F21 Pro I can just use MTKClient's `mtk da seccfg unlock`, and unlock the bootloader. Not sure what this script is doing special, although the dev mentioned that he exploits a hardware vulnerability?

I am scared to use it because its fully obfuscated
[Miscellaneous Android Development] Biden2020prez:
Funny that the OP said his tool exploits a "hardware vulnerabity". Heh! Its literally just a script running MTKClient. Great work, but a bit misleading. I'd be more amazed and impressed if you shared the raw script and just said "heres a script that uses mtkclient to unlock the bootloader that I wrote custom for the Qin F21 Pro", but the way you shared it was certainly misleading!
[Miscellaneous Android Development] alecxs:
to me it looks like bootloader itself is modified (lk partitions) which afaik is not the case for mtkclient. also vbmeta is patched and drivers installed automatically? looks like a good wrapper to me on a first glance. but I remember the base64 encoding stopped me from using it...
[Miscellaneous Android Development] Biden2020prez:
I see that now. it also has `a(m("xflash seccfg unlock"));` which is an MTKClient command. Not sure what he is doing with LK, good point. For VBMeta he is probably just flashing an empty one to disable dm verity.

And I agree it's a nice script. But I still do feel like it's a bit misleading. If this was something impossible before and he made it possible I would donate if I had the money. But I was able to unlock my bootloader by just running `mtk da seccfg unlock`. And it looks like his script does (almost) the same thing. I still don't understand why he flashed tons of partitions though.

Anyways, great job OP on your work, and thanks for your contribution, it looks like it helped out many people.
