Is there any solution to downgrade my a505f under android 10 and bootloader u5 to android 9

Don't Do that. Install the Synex Os 2.0.1 rom on your device.Its a damn good rom and there is no sound issue in this rom and this rom also has dual speaker mod.

TWRP for MIUI 11 Global Android 10

I had no trouble getting TWRP to work on MIUI 10 11.0.6 Global or lower. I was using LRTWRP. I upgraded to MIUI 11 yesterday and can't find any TWRP that doesn't bootloop or black screen. Does anyone have any suggestions on TWRP that works with GLOBAL MIUI 11. THANKS!

Hi, this twrp work well with android 10, you can't decrypt data in first boot but return to encrypt data in the next boots... I don't really why....
Search in youtube: How to flash TWRP and ROOT Android 10 - REDMI NOTE 8
You have the link of TWRP 10 LR Team link (G drive)
EDIT: I have tried again and the decryption works perfectly, it was a problem with an application to modify the selinux, without installing, everything is perfect.
If automatically re-encrypts your data, the password is your phone pin.

Thank God and to you people..after one whole day of struggle... Successfully installed Android 10 update indonesian rom and rooted and twrp installed... i am happy now
I have been struggling all day long with getting my N8P rooted - ever since I decided to give Android 10 a try there is no option to get it done.. I tried everything - all TWRP versions I could find both official and unofficial.. MiFlash, Fastboot, ADB.
I tried also that method when you patch the file (boot.img) with Magisk mngr. I watched thatKonah the Begonia Guardian's famous video numerous times. I even "clean all and lock"ed my phone by accident at one point. No way it works with MIUI 11/Android 10. Android 9 - no problems. What's weird - the same version of twrp (I flash them with adb/fastboot) once works flawlessly, then I can't flash it at all - phone softbricked.. back and forth.. what the f?? I guess I need to wait for another root/twrp/Android 10 rom - unless you have any ideas??
Can you explain the steps you have followed?

By what way did you upgrade to Android 10 with your rooted Android 9 phone? Did you upgrade by twrp or other means?

Is the ROM booting up or are you bootlooping?
It was bootlooping each time I tried to install Magisk via TWRP.

The differences between Android 9 and Android 10

I recently brought Rmn8p with miui 11.0.6 (global) , wait to unlock bootloader. After that flash preloader & lk then trwp and root.
I was wondering what's the difference between android 9 and android 10? Is it almost the same like I read at some post? Someone has updated to android 10 may share some viewpoints with us, thanks!
Already unlocked bootloader , root and xposed , phone recorder installed. Thanks to those pioneers.

Hey. I think this is widely discussed elsewhere. Just search for "MIUI Android 9 vs MIUI Android 10" in Google or YouTube. You'll find way more information there than you would ever find here regarding such generic topics. Have fun ?

Downgrade Realme 6 Pro to Android 10 not working

I tried to downgrade to Android 10 in my Realme 6 pro by official methods but when I try it says 'the current version is newer than the installed version'. This method is working fine with some other Realme devices but not mine. I real reason I want to downgrade my Realme 6 pro is because I can't unlock bootloader in Realme ui 2.0 yet. The official "in-deth testing app" isn't optimized for Android 11 yet. Do provide me some solutions please!
I am a Realme 6 Pro user as well and updating my phone to Realme ui 2.0 (with Android 11) was a huge regret as my phone is unusable since then- I can't unlock or dial calls or perform ANY action on my phone due to the touch screen not working at all so I tried factory resetting it but its back to android 11 again and same issue prevails. Downgrading to Android 10 was the only option left so I followed this official post and i got success in downgrading: https://c.realme.com/in/post-details/1387036088090091520

Thanks man! The answer was right in front of my eyes but I still struggled to found it. By the way, do you any Kernels for Realme 6 Pro? I am installing Evolution X and I need a kernel for my device.

Hey I'm glad my reply helped a bit But I don't have any idea regarding kernels for the device. You may try to post a dedicated question in XDA so someone who knows can answer...

your problem sounds more like data partition incompatibility
use CLEAN flash first (format data, not wipe) follow this tutorial
if it dosn't work, then start playing with FW
FW links
RN8 : https://xiaomifirmwareupdater.com/firmware/ginkgo/
RN8 T : https://xiaomifirmwareupdater.com/firmware/willow/
you can flash any region fw, (flash with recovery as normal zip)
just don't make mistake flashing ginkgo FW on willow or willow FW on ginkgo
you will break the phone !

ASUS ZenFone 2 Laser ZE601KL

I recently purchased the ZE601KL.
What CUSTOMROM can I use for this model?
I looked it up and found that I can install up to Android 10 with LineageOS.
However, I cannot hear sound from the speakers, do I need to install a patch?
Can I use CUSTOMROM for the 5 inch one?
Please teach me m(_ _)m

I am posting this using a translation.
Wording may be incorrect.
My apologies.
I am still in the process of installing CUSTOMROM from this.
Android 9 is installed.
I had to use the modified file because the sound is not coming from the speaker.
I was able to install Android 10 ROM, but no sound.
Is there any chance to get excited about Android 11 or Android 10 ROMs for this model anymore?
Please give up ……
