Modem a for a partition, and modem b for b partition. These are the ones a TMobile device has to flash when going to a custom Rom/another Oxygen build. These can be shared, etc. The st1 and st2 is for your specific device and uses fastbootd, but these can not be shared and will result in a soft brick if I'm not mistaken. Modem a,b is the ones for conversion if on T-Mobile,etc.

Or do I have to install Android 11 for the updates to work?
[Google Pixel 4a Questions & Answers] a1291762:
Google does not release security updates for both Android 10 and 11. The last Android 10 update was Aug 2020.

A custom ROM could presumably backport security fixes to older Android releases. I do not know if that actually happens.

And how does one install the September update on Stock w/o losing Magisk root? Is there a walkthrough?
[Google Pixel 4a Questions & Answers] a1291762:
Yes, there are multiple guides.

What I do (summarised) is

1 download the factory image

2 extract it and the embedded zip until you have boot.img

3 send that to the phone and use Magisk manager to patch it. Send it back to the pc

4 replace the -w in the flash_all script with --skip-reboot. Add these 3 extra lines to the end.

fastboot reboot-bootloader

sleep 5

fastboot boot patched.img

5 run the script

6 use Magisk manager to install (direct)

I haven't installed September's update yet. Didn't realize it was out.
[Google Pixel 4a Questions & Answers] amphi66:
Thanks, John.. . . . ..

I extracted and used Magisk to patch the stock Sept boot.img, but am uncertain about the "Flash_all" script. Are you using that rather than separately flash the separate commands:

fastboot reboot-bootloader

fastboot boot patched.img ?

I was thinking of these steps, but am new to the 4a:

adb reboot bootloader

fastboot erase boot (this step is uncecessary?)

fastboot flash boot magisk_patched_boot.img (the Masisk file patched from the Sept update

fastboot continue (to reboot the phone)
[Google Pixel 4a Questions & Answers] a1291762:
Since you can't get the (small) OTA, you have to install everything. That's what the flash_all script does. There's one for Windows and one for Linux/Mac.

Removing -w stops it from wiping user data.

Adding --skip-reboot and the other 3 lines will boot the patched image rather than the vanilla image, then you can flash from Magisk Manager.

Like I said, there's many ways to do this. Somep people use the full OTA image. Some people flash the patched image from fastboot rather than Magisk manager. Some people use TWRP.
[Google Pixel 4a Questions & Answers] amphi66:
This process is beginning to make sense to my thick skull .. .. one more question: you are replacing -w with --skip-reboot .... the double dashes are correct syntax for the replacement?
[Google Pixel 4a Questions & Answers] a1291762:
No. How are you hoping to install the September update by only flashing boot.img?

If you already have a given release installed then you only need to patch that release's boot.img and flash it to get root.
[Google Pixel 4a Questions & Answers] amphi66:
Got it, didn't seem to make sense. Thanks. Was the --skip-reboot (double dash) correct syntax?
[Google Pixel 4a Questions & Answers] a1291762:
Yes. Without --skip-reboot the phone will boot into the stock image. If you don't want that, you need to stop it and boot the patcheys image instead. That's what the last 3 lines do. Boot the patched image.
[Google Pixel 4a Questions & Answers] amphi66:
Thanks. Just wanted to verify that the (double dash) skip was the correct replacement for the (single dash) w. Ready to take the plunge!
[Google Pixel 4a Questions & Answers] amphi66:
@a1291762

one last (paranoid) check: does the following look like a properly modified flash-all.bat?

PATH=%PATH%;"%SYSTEMROOT%\System32"

fastboot reboot-bootloader

ping -n 5 127.0.0.1 >nul

ping -n 5 127.0.0.1 >nul

fastboot --skip-reboot update image-sunfish-rq3a.210905.001.zip

fastboot reboot-bootloader

sleep 5

fastboot boot patched.img

echo Press any key to exit...

pause >nul

exit

Thanks, John!
[Google Pixel 4a Questions & Answers] a1291762:
Your patched image is called patched.img right? If not, rename it (or change the script).

I don't use windows... Looks like it's got a different "wait for 5 seconds" thing? (The ping lines). Copy one of those instead of the sleep.
[Google Pixel 4a Questions & Answers] amphi66:

Unfortunately, I am back. The .bat file seemed to run OK -- there were a couple of "missing" notes, but no real problem. The phone has rebooted properly, but under System Update it still shows August 5, 2021 security update. I have attached a screen shot of part of the process. Any ideas? Thanks

[Google Pixel 4a Questions & Answers] a1291762:
The screenshot shows the beginning, but it's the end that is most likely to show useful messages...

All I can do is guess... I guess the phone installed, failed to boot and went back to the original slot. Or it just failed to install, causing it to boot up the old slot.

You can verify the booted system like this:

Settings -> About -> Build Number
[Google Pixel 4a Questions & Answers] amphi66:
Build number was 210805 confirming the Security Patch date. I we t through the process again w/ same results, then redownloaded the factory image again in case that was an issue.

This time it all ran thru w/o any errors until the final command: reporting "partition not found" when trying to flash the magisk-patched image file. I notice that command is "fastboot flash boot" where the very first command is "fastboot flash bootloader" does that make a difference?

Phone rebooted OK, but remaining on August update.

Updated my Platform tools (I had and older ADB) and this time all ran w/o error, but phone still remains on August Update. .. .. .. ..

------------------------------------------

Got it!

Turns out after removing the -w, the --skip-reboot must follow the update command, not simply replacing the -w. Perhaps a "feature" of the Windows batch file vs the Linux .sh?

Thank you again for your guidance. It is helpful to have an understanding of what is going on
[Google Pixel 4a Questions & Answers] a1291762:
Huh. That's interesting. I replaced the -w (I use macOS) and it worked fine. It could well be that the windows tools expect the args to be in a different order.

Glad to hear you got it working though :)
[Google Pixel 4a Questions & Answers] amphi66:
R

Actually ran it w/o the --skip-reboot altogether and then manually rebooted to bootloader to flash the modified boot. I found that change of order on a web post & will give it a try for the Android 12 update next month. Thanks again.

[8525, TyTN, MDA Vario II, JasJam General] shadowluan:
is it possible to use gps on my phone by using google maps with a bluetooth gps receiver? thank you
[8525, TyTN, MDA Vario II, JasJam General] audiobastard:
yes, but then you need to have an unlimited data plan too. Google maps downloads the maps in realtime as it uses your gps receiver to track your location. There are some free gps programs, but unfortunately, the one's you're probably interested in also require downloading maps in realtime as your gps receiver tracks you position.

The long and short of it is that you need a commercial software program such as Inav Iguidance (what I use), garmin, or tom. These are one time purchase based and your gps receiver doesn't use data so you don't need an unlimited plan. These use maps that are stored on an external sd card (typical size of maps and software is 1-2 gb). I recommend just coughing up the cash for the software............. or not wink wink.
[Xiaomi Poco X3 NFC Questions & Answers] wilsonhlacerda:
Experienced/advanced user here, but on old Sony and Samsung mobiles. Poco X3 NFC and PRO are my first Xiaomi devices. And I'm just about to unlock and flash them.

On (old) Samsungs for instance is HIGHLY advisable to do and safe store backups of critical partitions like EFS, first 100MB of device memory, BEFORE playing hard with custom stuff. Just because sometimes things goes wrong by themselves and can loose IMEI, brick. With the backups can circumvent lot of unexpected bad things.

Another fundamental thing to keep in mind on Samsung is to keep modem and bootloader (firmware) versions in sync, otherwise may have WiFi / Bluetooth / Data connection problems.

Well, now back to Xiaomi (Pocos X3 specifically): do you experienced guys on Xiaomi have some similar suggestions? What and how to do it?

For instance:

- backups in order to restore IMEI?

- backups in order to restore DRM (Widevine L1)?

- procedures to avoid other critical problems? (I already know about ARB, anti rollback)

- how to do above, which tutorials/tools are the best to backup/restore for instance? (dd commands? any apk? I'm afraid we should not consider custom recoveries trustful, because TWRP/OrangeFox are all unofficial and early development for Pocos X3)

Thanks in advance!
[Xiaomi Poco X3 NFC Questions & Answers] Yepi69:
I've bricked my device twice, to the point where nothing would boot up besides emergency download mode and everything was fine.

I know accidents can happen, but you can root and perform a manual EFS backup, luckily Xiaomi devices aren't the cluster f### Samsung/Sony devices are so your chances of screwing up that partition are very slim unless you're intentionally trying to do so.

Install a reliable recovery, a reliable ROM and you can't go wrong.

I don't think this device has ARB because I've downgraded and upgraded from version to version, region to region so many times now and nothing stopped me, so long as you keep the bootloader unlocked while you're not playing with ROMs (and even so Mi Unlock can still unlock your bootloader regardless due to the account/device token registered).

Xiaomi updates the modem's firmware per build so it's best to use an up-to-date custom ROM based off the latest build for optimal results.

You should backup the EFS and the persist partition so that you can restore the IMEI. But to do that you have to unlock your bootloader first.

Just recently switched from a op7t to the op8t.

I recently noticed it runs a warmer then my previous OnePlus device. As well as battery drain , fully stock. Running OOS.

My tempature varies from 38c - 45c. I have read anything higher than 38c is " high ". 3rd party app states average temp is 31c. With or without phone cover .

Battery seems to go much quicker than 7t. I understand the 120hz screen has a big role in that . But I'm hardly using the phone .

I still have 10 days if I wanted to return this device in for a replacement . At best buy , I'm wondering if I should swap it out ?

I've been " lightly " using this phone , thinking about pushing it sounds like it would raise in temp even more.

What do you guys think ? Swap or keep?

[Android Software/Hacking General [Developers Only]] D.lohuis@icloud.com:
I have installed Caos 11 on my Blackview BV9900Pro. The strange thing is I have to use the a/b version to make it work while it's an a-only device. I got Magisk and exposed to work.

To get the Flir camera to work I installed the MyFlir APK from the original Android 10 ROM from Blackview and I created a Magisk module that 'installs' the libraries and leptonserver bin file. It also starts the leptonserver at boot.

To get the heart rate sensor working I did the same but then for healthcare.

When I have time I will create a manual on how to install Caos 11 on the Blackview 9900(Pro). The only things I noticed up to now is that Volte doesn't work, the Flir camera doesn't work and the heart rate sensor doesn't work. O yeah, after first boot I had to factory reset to make it see/use all storage. Without factory reset Android storage shows just 2GB while it has 128GB.

Attached you find the Magisk Modules and the APK's. Let me know if it works for you on any custom ROM.

Edit 10-09-21:

I changed the MyFlir module. Now it wil also install the MyFlir app. No manual installation of the app anymore. I will do the same for HealthCare later.

Thank @backroot,

Great it works for you 2. Concerning saving I noticed I had the same issue. I almost never take pictures myself is why I haven't noticed myself. I got this resolved by installing myflir.apk again, without removing myflir app, from the following location:

/system/app/myflir

or

/system/priv-app/myflir

Hope this works 4u2.
[Android Software/Hacking General [Developers Only]] backtoroot:
Yeaahhhh! To re-install the APP over the old one did the trick! No issue with the save function anymore! 😎 Thanks again for your help!

Last issue I discovered with myFlir:

the calibration tool (the last point at settings - not the one on top with the flower/MSX) to adjust the real and thermal camera to be on same focus doesn't work at all. Nothing happens if I try to choose that function. As it's called something like "Picture Adjusting-Tool" it sounds too me like a separate APP or so which is probably missing in my installation.

I can't really tell if it ever worked as this was never an issue with the stock rom but since it works with my custom rom the position of the two pictures is quite different which makes the overlay of the thermal image a bit useless.

Any advice on this?

If you are trying to flash a GSI, you don't need it. You can do fastboot flash system GSI.img in the bootloader and it will flash. I have booted CAOS and LineageOS. Make sure you download the ab versions because the a only versions do not work for some reason. You could possibly do adb sideload in twrp afterwards for root.
