[Huawei Mate 20 X Questions & Answers] Zephels:
Good to know, at least there's a method to their madness. Thx for the info!

If I'm not mistaken, you will require root access to remove UPDATE.app download. It may not be possible with stock firmware, unless you factory reset.

Also disable Phone Access from app permission. This will prevent the app from reading your IMEI and Build Number to deliver update. After that reboot to recovery, delete cache and reboot phone. Hopefully that works.

As far as I'm aware, Chinese models AL00 and TL00 don't have random reboot issues for 9.1

It's limited to certain models of L29 (ie C185,C4332,C636)
[Huawei Mate 20 X Questions & Answers] kelvintisw:
A very strange experience this time after updated to 9.1.0.300. :confused::eek:

As I mentioned before. Apart from the 1st crash on the early morning of Thursday right after the update. There has been no crash until now (4pm, Saturday)! :confused::eek: :fingers-crossed::fingers-crossed::fingers-crossed:

Usually, when the 1st crash started. The frequency of crashes would start to happen fast and furiously, non-stop for every hour or every 2 or 3 hours! :confused::eek:
[Huawei Mate 20 X Questions & Answers] Maczimus:
It's a mystery. I had crashes frequencly but now it's fine :s

Dunno if its something i did, went to app gallery and updated apps, and under device administrators i found "google pay" got admin rights, so i unticked that. No crashes yet but sure it will come back..

Nvm, crashes is back.
[Huawei Mate 20 X Questions & Answers] kelvintisw:
Haha! Speaking of the devil...:D:D:D

I'm "waiting" for huawei.wallet to pop up and crash my phone for the 2nd time to prove me wrong...:cool::eek:

I start to suspect that Google Pay might be to culprit...!:cool::confused::rolleyes:

[Huawei Mate 20 X Questions & Answers] Zephels:
Give it time lol. Few things in life are certain; Death, taxes, & our random crashes!

Yeah like Kelvintisw said, generic response. Also, since only 10% have his issue, probably their own test unit is fine and most people who have this problem just rollback to 9.0 since it will be too much hassle to report & rectify. Only a few of us here & there are stubborn to stay at 9.1 and suffer through the tests ;)

Interesting thing i noticed in my test:

I downgraded back to 9.0.0.207, reformated via recovery, and then used iShredder 6 to fully erase any leftover files & app residue. After that, I upgraded back to 9.1.0.300 via eRecovery. After initialising, I skipped the setup & proceeded to home screen (ie only preloaded apps without any updates or logged in accounts)

5 mins after leaving it alone crash happened. This rules out any user-installed apps and it seems like either system apps or preloaded ones. I took screenshots and am doing some elimination to narrow it down...will update soon.

At any rate this issue may be resolved in 310, but it will be good if the crash cause can be found out before then, for our peace of mind :)
[Huawei Mate 20 X Questions & Answers] kelvintisw:
Good test and catch! :)

Yes! I would like to know what actually caused the random crashes too even if it is resolved in the upcoming 9.1.0.310.:)

The same YouTube video as you have played/tested in 9.1.0.300? :confused:

To me! The loudness of any types/sources of media play has increased nicely in 9.1.0.310. :fingers-crossed::highfive:

Okay! I have tested a simulation game in which there are a lot of voice/speech communications during the gameplay. Well! Not that good! :rolleyes: The voice/speech output fluctuation bug is still there but it is not as bad as in 9.1.0.300 even though the voice/speech seems to be increased significantly in game play as well. :)

As for random crashes bug! No crashes has shown up yet since 2 hours ago after updated to 9.1.0.310! A good sign so far at the moment! :fingers-crossed:

No doubt that 9.10.310 has restored the awesome audio quality and loudness in media playbacks for Mate 20X! :)

As for gameplay audio! It has improved just a little but further improvement is needed for sure especially so in the area of Voice/speech in gameplay! Let's hope the next firmware will address the gameplay audio quality issue!

.... and YES! No crash! :)

I don't have a nm card is there a way to install this ?
[Huawei Mate 20 X Questions & Answers] Zephels:
Noted and thanks for the info.

Seriously, thanks to him. I've been constantly checking and rechecking for updates to no avail, now thanks to the early upload all the problems are now solved!

Did you by any chance use Funky Huawei to flash your device previously? Or another method involving HiSuite where you need to change your DNS? Because of so, then the dload won't work.

In any case, do this:

1. Backup your device (messages, contacts, apps, files, etc)

2. Plug in your device and then turn it off

3. Hold both Power Button + Volume Up to Enter Recovery Mode

4. There will be an option to 'Download latest version and recovery'

5. Enter your WiFi details and proceed with download and installation

6. Once done, setup your phone like normal (note that it will do a full wipe most of the time)

7. After setup check your current version. If you're not already on the latest version, then proceed with the dload method.

Follow this.

Alternatively for step 5, you can also power off the device and then hold all 3 buttons until you see the recovery menu appear. It will automatically check and install the dload firmware.

Use USB OTG dongle and plug in a USB drive to the phone. It will work just like a nm card. Check your Mate 20 X box to see if you already have one.

where do you know that only %10 experienced this random crash problem. Your estimation is totaly wrong, i guess.
[Huawei Mate 20 X Questions & Answers] Zephels:
Just an estimate, I could be wrong. Then again, so could you :)

My point was, allot of people who upgraded to 300 did not experience the crash bug, according to this xda, the Huawei Chinese forums, Spain and Russian forums, Malaysian and Singaporean forums. The ones that did have the problem were very vocal and active in participating for solutions vs the ones that didn't and gave little feedback. That's why it seemed like more people had this problem. In contact, allot more people had the sound bug problem and that's why Huawei chose to fix that immediately in a small patch (albeit not very successful)

Nevertheless, the 310 update has fixed the crash problem and made many people happy ( myself included). Although some people still seem to have issues with sound still. Maybe 311 will help.
[Huawei Mate 20 X Questions & Answers] kelvintisw:
As of now. Everyone should be very happy running 310. Problem free at last except the minor in-game audio bug that should be fixed in the next version by Huawei!
