Updating via OTA overwrites the boot image, meaning you lose root. However, after completing the update, you can use a previously patched boot image to temporarily gain root so that you can perform Direct Install in Magisk.

As far as whether updating will fix an issue, I can't answer that. Personally I always recommend staying updated.
[Google Pixel 4a Guides, News, & Discussion] S.Mayer:
Thanks for the guide, OP!

I've just updated to the release version of Android 13 (TP1A.220624.014), and have Magisk 25.2.

When I used fastboot boot to temporarily boot from my patched boot image, Magisk didn't give me the option to "Install Directly", so I had to flash it myself. (I'm not sure if I messed it up somehow.)

Does installing MHPC do anything, by itself? I thought it was a tool that can be used up change system properties. I don't see any mention of what to change, and the above comment seems to say that no changes are necessary.

I currently can pass SafetyNet with just USNF, and my banking apps work. When I tried to setup a card for contactless in Google Pay, it given an error:

From what I've found, it looks like my next step is to use MHPC to pick another device fingerprint and hope that works. I'll update after trying that
[Google Pixel 4a Guides, News, & Discussion] V0latyle:
You probably didn't have root for some reason.

Correct, I need to edit that out. MHPC alone doesn't do anything without configuration

Negative. This is due to GPay shifting from SafetyNet to Play Integrity, which cannot be spoofed. See this thread. The solution for now is to use a modified version of Universal SafetyNet Fix which forces the legacy attestation.
[Google Pixel 4a Guides, News, & Discussion] S.Mayer:
That must be it. I thought I had checked for that, but Magisk does give me the option to Install Directly now, so there's not much else it could be.

That worked, thanks!

(For one of my two cards, GPay is giving me an error saying I need to contact the bank, but since the other one worked I can only assume that's unrelated to device security.)

So if I'm reading the thread (and the diffs between the original and the mod) correctly, it looks like the modified USNF uses the same principle as the MHPC approach, just more targeted. Meaning that it's still using a fingerprint for a non-HWKA device, but only for certain checks. Is that accurate?

I've spoofed my fingerprint with MHPC before, over a year ago, and it was kind of ugly because some Google services would refer to the spoofed device name.

I can see the mod uses the fingerprint from a Nexus 6P, but the Play Store and 2FA prompts still call my phone a Pixel 4a, so that's nice.
[Google Pixel 4a Guides, News, & Discussion] V0latyle:
More or less. But the device fingerprint actually is the easiest part of the puzzle - all it means is that the device, as well as the Android build running on it, are approved by Google. The only time this is really ever an issue is when you're using a custom ROM that doesn't already spoof a fingerprint for something else. All MHPC does is say "this is a Pixel 5 running factory Android".

See https://xdaforums.com/t/magisk-module-universal-safetynet-fix-2-3-1.4217823/post-87199557 for a more concise explanation.

What the modded USNF does is essentially force the SafetyNet attestation, which USNF has pretty much always been able to fix - the few exceptions being those with "unapproved" fingerprints as described above that require using MHPC. Unfortunately, this is just a temporary fix, and the only thing really on our side is the high degree of fragmentation among Android devices; anything below Android 8.0 is not capable of passing MEETS_STRONG_INTEGRITY, so these devices depend on the legacy SafetyNet. If app developers (including Google) decide that they want to exclusively use Play Integrity, and remove any legacy support for SafetyNet from their applications, there will be no way for us to use those apps on rooted devices.
[Google Pixel 4a Guides, News, & Discussion] X vu S:
I used this thread to unlock/root my phone, very grateful for all of this.

Currently, I have the pixel 4a unlocked Android 13 (TQ3A.230605.011) with Magisk 26.1 (26100)

In this thread, there are directions for Unlocking Bootloader, Update, Root, ect but unless I missed it, there was no mention of Relocking Bootloader, is this possible? Or, directions for how to return this back to original factory with a closed bootloader, or is that no longer an option?

For example, my partner messed up her phone (water damage) and I ordered a new phone for me and decided I'd use my current pixel 4a for her and transfer her phone to this unlocked (rooted) phone and figured I should lock it and put it back to factory before I transfer her phone over. She doesn't need an unlocked rooted phone...

At first thought, I was just going to install the stock image bootloader and then lock it but after reading, I don't want to change bricking if that's not the correct method or if it's simply no longer possible?

I've googled a bit and reading some mixed signals about this but I'm wondering if anyone here has any insight they can share?

Or a link to instructions?

appreciate,
[Google Pixel 4a Guides, News, & Discussion] V0latyle:
Use the Android Flash Tool to flash the latest update, and select the Lock bootloader check box.
[Google Pixel 4a Guides, News, & Discussion] X vu S:
I uninstalled the Magisk and restored the image file during the uninstall process. It rebooted.

Now, Im using the flash tool to flash it and lock the bootloader but when I connect the device it gives me this Android USB driver notice but when I checked the driver it's up-to-date.

I'm able to connect the pixel 4a but When I attempt to flash, it says preparing and then times out after two minutes and says, "flash failed - network header response timed out"

Couldn't I just manually flash the image file using CMD and then simply lock the bootloader using the fastboot flashing lock CMD in a terminal or will that brick it?
[Google Pixel 4a Guides, News, & Discussion] V0latyle:
I was trying to help you find a simpler option, which is why I recommended the Android Flash Tool

As long as you've restored the device to stock completely meaning both slots, locking the bootloader is fine.

So, in this case, use the factory image method in the OP, and make sure you use the --slot=all flag when flashing. You can use the included script, but you have to use the flag for each flashing operation. Here's the long hand:

fastboot flash bootloader --slot=all <bootloader image>
fastboot reboot bootloader
fastboot flash radio --slot=all <radio image>
fastboot reboot bootloader
fastboot update -w --slot=all --skip-reboot image-sunfish-buildnumber.zip

It should end up in fastbootd mode once completed

fastboot reboot bootloader
fastboot flashing lock
fastboot continue

There might be a simpler way to do this, as I've been doing some reading:

fastboot flashall -w

hey idk if you’re still active but i would really appreciate some help with my google pixel. idk if we can dm somewhere but here is basically the just of things vvv

So basically I haven't used my rooted phone in a few weeks and have just been letting a family member use it. Anyways I get it back today and see that pokemon go is no longer opening and my root access checker is saying that root access is not properly installed on the device. Even though I've been using root access for about 6 months just fine before taking a break. No clue what could've caused this or how to fix this because I have no knowledge on this, I was just able to root it in the first place via a YouTube video.

I don't do private support, and there was no need to copy your post into PM. I prefer to keep conversations like this out in the open because they might help someone else with the same question.

Follow the first post of this guide to re-root your device using the "Initial Root" guide. You'll need to download the factory firmware package that matches your current build: to see what your current build is, either drag the windowshade all the way down and look at the bottom, or go to Settings > About phone > very bottom under Build Number.

All you should need to do is patch the boot image in Magisk and flash it to your device.

Do not use any other root solution.

Make sure you only have one instance of Magisk installed on your device. If the Magisk app was previously hidden, you might still have a stub somewhere.

Hi

The remote control volume keys are reversed, I tried to reset and on device control change TV but nothing, any solution?

I was having the same problem with a TV remote controller standard but I solved it by remapping the keys

I have a FireTv 3rd Gen with Fire OS 7.2.7.9

Any fix?
[Redmi 9 / Poco M2 Questions & Answers] TomekParuszewski:
I tried installing crDroid (unlock bootloader, uploaded FW, recovery SHRP, then install ROM) and after reboot the phone would go back to recovery.

By mistake I "installed" SHRP from ZIP package (I thought I need to install latest recovery file to install ROM with android 12) and phone went into reboot loop, I can't do anything, any key combination doesn't help - I can't even turn it off.

help!
[Redmi 9 / Poco M2 Questions & Answers] TomekParuszewski:
I opened the phone, disconnected the battery, but nothing happened - still bootloop

I'm planning to use SP Flash Tool

Immediately after connecting USB C, the phone boots into bootlop (after disconnecting and reconnecting the battery)
[Redmi 9 / Poco M2 Questions & Answers] Sergij-SApcPro:
What happens when you flash the custom ROM?

Try to flash the stock firmware and miui

again. Download the latest miui recovery ROM for Lancelot and copy it to the sd card. If you can still boot into recovery you can connect the phone with a PC.

You can also try to reboot into bootloader if the reboot options work from sharp, if not connect the phone to a PC with adb and fastboot installed on it and type:

adb reboot bootloader

And now if you are in fastboot you can do anything, you can try to reflash the firmware, recovery etc.

I personally don't use SHRP, it was really buggy and not great. I use the twrp from this link: https://xdaforums.com/t/recovery-twrp-unofficial-twrp-recovery-3-6-1_11-0.4421301/.

Thanks for reading and I hope u succeed,

[Redmi 9 / Poco M2 Questions & Answers] Sergij-SApcPro:
U can also try to flash it with MI flash tool.
[Redmi 9 / Poco M2 Questions & Answers] TomekParuszewski:
Operation completed with status [ ]. It looks like there should be a * in the middle and then it would be a sign to me that the ROM is loaded.

At the time of writing, no key combination was working - I can't get into Fastboot or Recovery. I let the battery run out for that moment.
[Redmi 9 / Poco M2 Questions & Answers] TomekParuszewski:
That's what I'll do first, then move on to the solution below.

I opened the phone and disconnected the battery, but plugging in the USB cable immediately turns the phone on and bootloops again.

I'm using Linux and Windows, and one user hinted at hacking the USB driver so I believe it won't boot the phone, only then will I have communication? Other than that I don't know how to do it anyway.

For now, after the phone's battery runs out, I'll try with this solution

Other versions of SP Flash (newer) other than in the package with ENGROM didn't work with DA file with manual from links given above - it had to be the one from the package. SP Flash showed errors and crashed or informed about wrong file.

Yes

I think that if you go through the MTK Bypass process carefully, step by step, you may succeed, as I did.

I have a USCC 6800 as well, tho I've modded mine, however from the factory the only thing that is disabled/missing is MMS. ICS should work right out of the box, so I don't believe he will need a cab for this.

They are running extrememly old radios/roms tho, like ver 1 rom and ver 1.x radios....

I highly recommend you look into upgrading your phone to a newer radio and custom rom as it will dramatically improve your phone. Mostly you will get RevA EVDO when it comes to your area. Also GPS works and the phone seems to run a lot faster.

Do a lot of reading first, mainly learn to use QPST to back up your phone's programming and after flashing write it back to the phone, verify your EPST info is correct as I just found out recently that mine wasn't and this was why my EVDO didn't work. Other than these 2 things, the rest of the guides on how to flash your phone should get you thru the rest of it.

Any questions, feel free to PM me and I can point you in the right directions.
