[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] mrtati:
Hi,

I have a global variant of S20 with Exynos chipset running rooted stock Android 10 with G980FXXS2ATE7 firmware.

Root was done with Magisk and it was properly working.

I installed a Magisk extension that caused the initial boot loop, but Recovery and Download mode was working. I was trying to install TWRP but that failed to load with some DTBO related problems. So I restored the stock recovery for Android 10 and then choose to flash the Android 11 version of dtbo alone without any additional files from that package, because I was hoping that it would make TWRP work. So I have a combination of stock files for Android 10 + corresponding rooted bootloader and stock recovery + Android 11 version of DTBO.

This was a big mistake, as since the device is rebooting every 30 sec. It only shows that the bootloader was unlocked and afterwards the "Samsung Galaxy S20 secured by Knox" screen. It stays here for a while and then reboots automatically.

Download mode and recovery are inaccessible. They simply do not appear, not with any key combination via which they worked earlier.

If I plug the phone into my laptop, there is absolutely no USB traffic, it is not recognized as a device.

Odin does not see the device either (as there is no USB device recognized by the OS).

The only thing I can do else is if I hold the Vol down + power button for a while and then plug in the charger when the screen goes dark, then the charging logo appears without showing the percentage of the battery. I stays there even if the unplug the charger. When touching the buttons, it goes back to the boot loop.

I have not found a way to power down the phone, even pressing and holding any combination of Vol up, Vol down and Power buttons.

I think the problem is that neither Recover nor Download mode can boot and this is because of the wrong DTBO file that I flashed.

Do you have any idea how I could repair and reflash the working DTBO file matching the firmware on the device under these circumstances?

Is there any trick for Exynos to boot from the SD Card like there is something for Qualcomm based phones?

Or any other way via which I could trigger some activity on USB?

Thanks for any suggestion
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Kenora_I:
Try launching fastboot devices while holding fastboot keys.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] mrtati:
Thanks for the suggestion!

I solved the problem finally.

It is strange, but recovery and download mode started to work with the hardware buttons after I removed the SD Card from the phone. I do not know how this is related, but afterwards I could flash with Odin and after reflashing the original firmware and the the usual vbmeta zip, the phone booted up properly.

Afterwards, I could reflash the magisk patched bootloader and regained root access as well.
[Magisk] neelchauhan:
Back in May when topjohnwu joined Google, he was told he's not allowed to maintain Magisk anymore:

. For some reason, this information wasn't broadcasted widely.

Because of this, the Magisk GitHub has gone dry: https://github.com/topjohnwu/Magisk/

Today, I can root my OnePlus 8 running LineageOS 18.1 (or Android 11 in general) with Magisk and pass SafetyNet. Maybe we'll have some root with Android 12. But come Android 13, or even 12 if something changes, what will we do if Magisk isn't maintained?

I propose we fork Magisk and continue developing it from there. This thread exists mainly as a discussion about a possible fork.

Sadly, I don't know much about Android development myself. I've only gone as far as making a flashable ZIP (if even that) for a Moto Z2 Force Sprint APN fix back in 2018. Well, maybe it's time for me to learn (Full disclaimer: I am a FreeBSD committer/developer, more packaging work but some kernel/driver stuff also, but then Android is based off Linux not BSD).

To mods: Sorry for making another thread. I wanted to edit the title of my previous thread, but couldn't.

Hello all,

I have Realme X50 5G RMX2051.

Unfortunately I upgraded to UI 2.0 and now I cannot use the Android Auto.

So I want to downgrade, but here is no official file.

Could you please help me with a solution?

How can I return to stock ROM, or change to EU ROM?

Thank you!
[Realme X50 5G Questions & Answers] Kenora_I:
Does the bootloader change between those two versions?
[Realme X50 5G Questions & Answers] gdimitorv17:
Hello, I cannot answer this question. If you tell me where to look I can tell you. Do you know how I can change the ROM to the global one? Or maybe to downgrade manually, because Realme does not have a file for downgrade of this model.
[Realme X50 5G Questions & Answers] sparck1206:
Hi, I got RMX2051 for a while, and still find ways to change the ROM version to EU.

But unfortunetely, Realme locks everything on this phone, I think that's the reason why there's almost no resources here.

By the way, if you just wanna use Android Auto, maybe you'd install it through APK file.
[Realme X50 5G Questions & Answers] gdimitorv17:

[Realme X50 5G Questions & Answers] sparck1206:
I found Realme X50 5G (Realme UI 1.0) stock ROM here.

But, it shown in Chinese Simplified...

And here is the tutorial from OPPO ColorOS community. (It's the same Recovery with Realme.)

I'd did a downgrade UI procedure once few months ago, but failed, because the Recovery is going to check the version of Realme UI, whether it was older than installed.

Anyway, if you'd decide to do this, please do a completely backup of your data first.

May this help you, and good luck ! :D

[Shield Tablet Q&A, Help & Troubleshooting] yenalsekim:
Hi,

Long time reader, first time poster...

I've got a K1 tablet and I've been trying to flash the rom but I keep getting the same message.

I've tried 4 different ROMS with the same result.

It is limping along with RR ROM but I can't even get stock ROM on it now.

It is a K1 for sure and I've been very careful about the files i'm trying to flash are for the K1.

From the look of the message it seems as though the device description is NULL

Thank You for any help

[Shield Tablet Q&A, Help & Troubleshooting] Joeysaur:
Been trying to fix this myself all day. as long as you're certain you have the right ROM (and it looks like you do) and that you're on the right bootloader, you can simply remove all of the checks in the installer and force it to install even though it thinks it's the wrong device.

using 7zip, open the archive of the zip you're going to edit, find META-INF, com, google, android and right click/edit updater-script.

remove "

assert(getprop("ro.product.device") == "shieldtablet" || getprop("ro.build.product") == "shieldtablet" || getprop("ro.product.name") == "shieldtablet" ||

abort("This package is for \"shieldtablet\" devices; this is a \"" + getprop("ro.product.device") + "\"."););"
[Shield Tablet Q&A, Help & Troubleshooting] ogremalfeitor:
Also try different TWRP versions. Some of the latest for this device are problematic (stuff like not showing the micro sd card inside TWRP even if it is formated as fat32) and also give strange errors.

If the latest one isn't working, try the previous one from https://dl.twrp.me/shieldtablet/ (twrp-3.5.0_9-0-shieldtablet.img works fine for me, while 3.5.1 does not), or for certain older custom ROMs based on the stock ROM an even older TWRP before that may work better.

When you find a stable TWRP that works with your favourite ROM then you should be fine.
[Shield Tablet Q&A, Help & Troubleshooting] Nriku1:
I can confirm that latest versions (3.5.1) does not work properly with our tablets. 3.5.0 does.
[Shield Tablet Q&A, Help & Troubleshooting] yenalsekim:
@ogremalfeitor​

Thank you.

I had given up on this until today when I found my k1 behind the couch and decided to give it another shot. I remembered/googed the problem and I was psyched to finally see "somebody else" with the same problem.

Then I realized it was my thread.

Goofball. Still laughing at the absurdity.

Anyway, I wanted to immediately thank you for the advice with such an old tablet.

Tune in next week when I exhume my TF101 from under the bureau.

Dear All,

I've purchased an iMATE JAQ from ebay, but it doesn't have any logo carrier.

I don't know it's locked to which carrier!

I tried with my unlocking supplier, to unlock it from AT&T/Cingular, but he said 'it is not found' .

Now,

whoever will unlock it for me is asking me 'to which carrier it is locked' , which I don't know!

How will I know to which carrier is it locked?

I've also got this info from the System Info:

Windows Mobile 5.1.422 AKU 3.2.0

Or,

someone could help me how to unlock it.

I've tried many ways, but non worked.

Thanks.

[Samsung Galaxy A42 5G Questions & Answers] TheVideoEffect:
Hello! I was messing around with key combinations, and I found that in the default android recovery on this phone, you can enter a Fastboot mode, and ignore the download mode that samsung phones traditionally use. I can't seem to get it to communicate with my computer, and I was wondering if it would be of any use to unlocking the bootloader on this device.
[Samsung Galaxy A42 5G Questions & Answers] Kenora_I:
Fastboot mode is a way to unlock the bootloader.

Download mode and fastboot would be the same thing

fastboot oem unlock does this same thing

It would be nice for a picture though.

Easiest way to avoid Playstore hassles when reloading is to use ApkExport to make installable copies of all the apps you load. Can be transferred between devices too. I don't need Playstore to reload, reloads go much faster and there's no guesswork.

Freeware with no ads... hard to believe it's on Playstore🤣

APK Export (Backup & Share) - Apps on Google Play

Manage and extract your apps.

Thanks I'll try

I use it for my system updates too. That way on a reload I have everything and it's known good.

[Philips, Sony, TCL Android TV] jconnell:
I'm trying to get my TV and my JBL Link Bar to play nicely together. Since the Link Bar also has Android TV installed, they frequently fight over who should have use of the audio output. The result is that often when I turn my TV on, no audio comes out of the Link Bar. I have to go to the CEC menu, tell the Link Bar to go into Standby, wait a few minutes, then turn the Amplifier switch in the same menu and somehow the audio starts working.

I'm interested in somehow automating this process either via ADB or SSH, possibly through sending some CEC commands with libcec.

Has anyone solved a similar problem? Any suggestions / tips?

Any updated howto? There's a page in the wiki listing some tool (the URL to that is dead now though), but it's unclear for me how to use it, even though it's described pretty detailed.

I want to dump my ROM because today, after many attempts, long searches and waiting I've finally gotten my ROM just the way I like it, and I want to be able to reflash it as is. I'm now using Sprite Backup (came free with my device), but that doesn't do a full ROM backup, so I'd have to flash back the ROM and then use Sprite Backup to restore my own stuff.

Any help on this would be really appreciated :D
[Xposed Framework Development] MR640445:
Hey guys.

As you may know many developers try to use some security option to check if app is being Reversed Engineered or not for example they check signature of APK file. If the answer is "yes" , then app will be closed automatically and you can't use it.

I want to know is there any way to avoid exiting apps when they are Reversed Engineered using "XposedFrameworkmodule".

A nice way to do this is using Frida but it is not working always.

Try this - Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number).
