Unofficial LineageOS 18, that I have tested, failed to update and I have returned to CRDroid. I have installed CRDroid 8.5 and Nikgapps core. System started OK and behaves normally. SHRP has no acces to data, so it doesn't fully support this rom. Will OS with gapps survive update?

Edit: just have noticed, that wi-fi 5GHz doesn't work. But I don't remember if there were wi-fi problems on other roms or this is a new thing due crDroid.

I have checked 5GHZ WiFi a bit more with WiFiAnalyzer:

On crDroid 8.5 channels 149-177 don't work at all. Channels 36-64 and 100-144 sometimes shows activity for a moment, but then stop working.

On LineageOS 18 channels 149-177 don't work, but 36-64 and 100-144 seems to be OK.

On MIUI 12.5.5 EEA all works.

Is anything else not working on crdroid latest rom. I am a newbie and haven't rooted or unlocked the boot loader of a phone. So I am scared if I do anything wrong. I searched on the internet and found that this rom works best on redmi 9 prime. I have a few questions..

Could you please refer me to some good guides and what recovery should I use?

I found this video but it is for crdroid 6.1. Are the instructions still the same?

As some people on this forum are saying that the phone's performance is sluggish with this rom, is it still there or the performance is now fine?

Thanks
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] morfikov:
TWRP/SHRP doesn't support A12 yet, so there's no way to decrypt data.

Update is simple -- you flash new ROM and new version of gapps after it from the recovery mode. All user data remain intact and the system will work just fine after the update.

Wifi 5ghz works fine in my case. Some channels can be restricted by regulatory domain, i.e. the country you are from.

In my case, everything works well.

Use SHRP -- it officially supports Redmi9.

Check this HOWTO to avoid stress:

https://xdaforums.com/t/guide-how-to-unlock-and-root-xiaomi-redmi-9-galahad-lancelot.4326097/

Performance is good, at least in my case. From time to time it can lag but I think it's a matter of apps you use.

One more thing.. Some websites said that I need to downgrade it to miui 12.1. My current android version is miui 12.5.4...I hope it won't cause any issues.

Great guide.. will surely test it out and update my progress. Thanks ☺️
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] morfikov:
I'ts about the firmware-ROM match. If you want to flash a custom A12 ROM you should have an A12 stock firmware, and if you want to flash a custom A11 ROM, you should have an A11 firmware. If ROM and firmware don't match, you can experience some issues. All the firmware can be found here:

XM Firmware Updater

The ultimate script that provides firmware packages for Xiaomi devices.

xiaomifirmwareupdater.com

Basically I download the newest firmware package and flash it from time to time.
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] Helium7903:
Does the country matter? I have India's latest version, do I need to flash china's firmware. So I can't flash crdroid 8.1 because it is A12 Rom and redmi 9 has A11 Rom?

Also if I keep reflashing.. All my data and settings would be deleted wouldn't it?
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] morfikov:
I think so. I''m from Poland, so I flash only EU or global firmware depending which one is the newest.

There's no A12 firmware for redmi9, but you can use the latest A11 with crdroid 8.5 and it works well.

Channels 149-161 and 165-173 are allowed in Europe with power limited to 25mW. See: https://en.wikipedia.org/wiki/List_of_WLAN_channels

There is no problem with these channels on MIUI and they work well on my Poco X3 Pro with LineageOS. Maybe crDroid doesn't properly follow regulatory rules?
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] morfikov:
Try checking the systemlog, see here:

[SOLVED] Android devices can only detect Channel 149 153 157 161 on 5GHz Band

greetings from past few months I have noticed a strange thing that all my Android devices (phones, tablets and even Chromecasts) can ONLY detect and connect to Channel 149 153 157 161 165 on 5GHz band Apple devices (iPhones and iPads) can see and connect to any 5GHz Channels (like 36 40 44 48)...

[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] popej:
You are right, this is similar problem. When I reboot phone in airplane mode, then I get all channels working. If I enable GSM and restart WiFi, then channels 149 - 173 stop working. I can see in logcat, that country is set to PL, but regulatory info looks the same (or I don't know what to look for).

Just installed the rom, works great.

Only issue i have (for now at least lol) is that on the latest build videos that are 1080p on newpipe and vlc lag a lot.

The same videos dont lag on the default gallery app.

I attached a newpipe error report, myabe that helps.
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] morfikov:
In my case, there's no problem with new pipe 1080p. I can see that the net transfer is around 500kbit/s and nothing lags, everything works smooth.

This is the first custom rom I've flashed. I've been having trouble with it shutting off by itself or shutting off when I click the power button.

[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] Redmi9guy:
I have two redmi9 phones and have installed this build of CrDroid on both and they are both up to date (7.16).

On both devices I have noticed that the screencast does not work correctly.

It can detect google home speakers but cannot detect televisions or chromecast devices.

I have tried on two different brands of TVs (one Hisense and one Toshiba) and neither television appears on the cast list on either phone.

This is the only gripe I have with this custom rom,

everything else appears to be working well enough.

Would appreciate if you could also test to see if screencasting is working for you or if you can advise if there is a way I can manually fix this.

Might be talking out my ass but this may help in some way?? (I did some digging online and saw some posts about android 6 changing miracast stuff or something and apparently some people hacked generic casting using HAL (whatever HAL means) in other roms for the specific device's chipsets or something).

I've just installed the latest ROM, (came from MIUI 12.5.4 ID) and after some hour i realize that Google apps (Youtube, Drive, Play Store etc.) and WhatsApp became slower to load than other app, not lagging but just slow to load compare to other apps. Any idea anyone?
[Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.] helmen:
Excuse me for asking this question.

I end up with a rotated phone with the "MIUI Global 12.0.1 stable" version.

Before trying a different room I wanted to update the firmware as I read on this post of yours.

The automatic update ("check for updates") doesn't go then I was thinking of updating by hand through the site you passed on.

The questions are:

1) Don't I have to upgrade progressively to the version I am interested in ?

2) Can I safely do the update from the interface (I pressed the logo 10 times to make the advanced setting show) or do I have to go through recovery ?

3) is the downgrade possible should I need an old firmware again ?

thank you very much!

EDIT: from the interface i get this error:

"Can't verify update

Couldn't verify update package"

I'll see if I can figure out how to update the firmware from the recovery :(

EDIT2: I read the faq and it says this "Flash it using TWRP or any custom recovery. There’s no need to wipe/format anything before or after the installation." Then I rebooted into recovery, went to the "install" menu and chose the file.zipr to install.

Rebooted, it works though the rom version is the same.

Fair enough though since I didn't update the rom but only updated the firmware, however the faq also says that:

"How to check the updated firmware?

Usually, the modem gets updated with newer firmware, you can check it in Settings > About > Baseband."

But my baseband version is "unknown." Maybe it's because I don't have any sim mounted right now?

[OnePlus 8 Questions & Answers] Fumetsu_Guritto:
Hello, my goal is to flash TWRP onto both Slot A and Slot B.

I've flashed TWRP into Slot A, while Slot B is flashed with LineageOS recovery, currently.

I'm pretty sure I then flashed the OS/ROM with TWRP into Slot A but afterward I had a warning that read, "No OS Installed" - I thought it was a fluke, I rebooted System and it went back to TWRP with Slot A active.

I manually switched to Slot B and rebooted System and LineageOS loaded. Rebooted into recovery and discovered Slot B is still using LineageOS recovery.

From there, in the recovery interface, there's no option to manually change back to Slot A. Rebooted into fastboot and connected phone to PC and ran command:

fastboot set_active other

This switched back to Slot A

I rebooted the device which loaded TWRP on Slot A.

At this point what do I need to do to install TWRP onto Slot B and flash LineageOS onto Slot A and Slot B?

I assume through TWRP on Slot A - I can flash TWRP onto Slot B. Then manually change to Slot B - reboot into recovery and verify TWRP is installed on Slot B?

Doing this of course, will break (assumption again) the LineageOS installation and will have to re-install LineageOS.

Once verified, flash LineageOS onto both Slot A and Slot B.

I feel like I missed something but honestly I'm using multiple guides and I feel I'm going to end up breaking something since not all guides align well.

I know this is a noob question, so I apologize, but I am trying to follow guides, none of which are instructing from A-Z the processes to achieve this goal. I have no issues following instructions, if I did, I'd have broken linux boxes, including a linux server.

I'm willing to start from scratch if I have to, I just want to get it right once and for all.
[OnePlus 8 Questions & Answers] azoller1:
This should be posted in the Q/A section.

Anyways, you can simply flash the twrp img to both slots using:

fastboot flash recovery_a name_of_twrp.img
fastboot flash recovery_b name_of_twrp.img

Then, once TWRP is flashed, just flash the installer zip after flashing a rom to keep twrp flashed to both slots.
[OnePlus 8 Questions & Answers] Fumetsu_Guritto:
This is in Slot A

Completed commands without error. Instead of installer zip, I have the twrp.img

Advanced > Install Recovery Ramdisk > select twrp.img

Swipe to install

Then instead of reboot, the instructions I'm following says to go Back into Advanced and then select Fix Recovery Bootloop then Swipe to confirm.

Here I receive an error related to magisk (Error 1) - Error patching kernel

The error message is: cd /tmp/repackorig/ && /system/bin/magiskboot hexpatch kernel ...

If I reboot system - I'm thrown back into TWRP recovery interface.

This indicates that I need to install the boot.img

Install > Tap Install Image > Select boot.img > select Boot partition > Swipe ton confirm

[IMAGE FLASH COMPLETE]

Reboot System is selected and LineageOS loads.

Open Magisk > Install > Patch boot.img

However, when I first installed LineageOS and set it up with Magisk and TWRP - I had already patched the boot.img - literally this happened yesterday.

Would I need to do it again? I would assume not.

So I go back into TWRP > Install > Image > select the Magisk patched boot.img > check the box to install on both Slots A and B > Swipe to confirm

LineageOS loads.

Now back to TWRP to complete the process of permanently installing TWRP Recovery:

Advanced > Install Recovery Ramdisk > select twrp.img

Tap Back into Advanced > Fix Recovery Bootloop > Swipe to confirm

This time no error - SUCCESS!

Reboot System, but boots into TWRP. No access to LineageOS.

In TWRP I go to Reboot > Select System Partition with Slot A active and it once again reboots into TWRP.

I repeat the process this time selecting Slot B and again reboots into TWRP.

I go back into TWRP, Install > Image > Magisk patched Boot.img > Reboot

LineageOS loads.

Is this the correct process? If so, I imagine that after flashing TWRP onto both Slot A and Slot B, I need to repeat this process on Slot B now?
[OnePlus 8 Questions & Answers] Fumetsu_Guritto:
Also another assumption - is the magisk patched boot.img an actual nandroid backup? Because it flashed the exact image (apps/settings etc..) that I had patched with magisk.

However, if it is, for whatever reason a good portion of my apps are broken. When I open them - they crash. I have to uninstall the app and then re-install it from Aurora Store.

It's not a big deal but I would love for the image to be 100% complete without the apps or even settings being broken/different. But maybe I'm getting ahead of myself here.
[OnePlus 8 Questions & Answers] azoller1:
I am not sure where you are seeing Advanced > Install recovery ramdisk in twrp. You should never have to used the advanced menu in twrp, unless for very specific reasons.

Ok, lets assume you are running the latest stock OOS.

1. First, you unlock the bootloader and can now use fastboot.

2. Reboot to bootloader

3. At this point you flash the twrp.img file to both recovery slots like i mentioned in my other post.

4. At this point you have twrp forever until something else overwrites the recovery partitions (flashing rom, flashing other custom recovery, etc).

5. Now, you need to factory reset, go to reboot then switch to the inactive slot, dont reboot, go back to install, then flash the rom zip file.

6. After flashing the rom zip file, flash the twrp installer zip file to overwrite the rom recovery.img so you can retain twrp.

7. Then you can reboot system and you will boot to the other slot where the rom was just flashed and everything should be ok.

Since twrp for the 8T is still not fully stable, but works very well, I dont think its good to flash .imgs directly in twrp, im sure it works but I usually just flash compatible zip files in twrp and use fastboot manually to flash a specific img if desired.

For magisk, the dev states in the instructions that flashing in twrp is not recommended (for the 8t in this case) and is better to boot the patched img from fastboot then go into magisk and direct install. Flashing using fastboot should work 100% of the time without issues. I have always just flashed the patched boot.img directly in fastboot and reboot with no issues.

However, if you prefer to flash in twrp, you must reboot back into recovery (reboot then press recovery) after flashing the rom and the twrp installer, so your device is updated to the other slot where the rom was flashed. Now you can flash magisk and it will flash to the correct boot.img slot.

I have no boot or recovery but do have file download mode. But since there's no KDZ for this phone I'm a bit stump.

Before funning the Raw file loads I was able to get into fastboot but it was very unusual in that it didn't say which was the active slot. I tried all fastboot commands to try and set the active boot slot but no go. Weird message about can't set slot on unlock BL. This was an Unlock BL phone, now who knows.

My thought are the phone just doesn't know where to boot from. is the a Laf or Op problem?
