Downgrade by HiSuite - is it possible or not? - Honor 10 Questions & Answers

Hey everyone. I'm an owner of Honor 10. I used to have Android Pie on my device already, but for now, I'm working on the Oreo again and temporarely blocked offcial updates.
I have a question - do you also miss downgrade option in HiSuite? When I was operating on... 9.0.0.162 I guess, option was nowhere to be seen. When I received update to 179, I checked Hisuite and downgrade option was brought back. I reverted to Oreo instantly, because I was not happy with the way Pie is working.
At the moment, I'm using 8.1.0.159 with little bit late security patches. But I guess, that's the price for great running OS.
If I'm ever going to try Pie again, I need to be sure, I can easily go back to older system, in case something will be wrong. How is it with you?
Best regards

same here, call recording is a must

For now, I'll just stick to Oreo. If something will change here, please let me know.
Thanks!

Z5compact (stock out of the box) and question how to flashtool (Nougat),bloody newbie

Hi community,
as far as I read nougat has been torn back from sony. Anybody updated before and has a smooth experience? Would like to update too.
Downloading and starting flashtool does not give me the check updates tab, so is anything wrong or has the device to be prepared?
Does this way need root or unlocked bootloader or something else?
I hoped taking a virgin z5c and flashtool would fit to check for updates, find the device and firmwares according to, choose one of and flash?
Isnt it that easy? Any ideas when nougat from sony official will be provided once more?
Thank you
There were a couple of serious bugs in the Nougat release, hence the draw back by Sony.
Maybe in a month or two, we'll see a fully working Nougat ROM for Z5C.

I'd suggest to wait too. Backup TA, Root and use Xposed instead. The only thing that is a bit more handy is split screen mode. I have audio bugs and thermal issues running nougat.

Honor 9 and Oreo 8.1?

Will Honor 9 get Oreo 8.1 in near future? Does anybody know?
Also second question, is it possible that we will get next Android P?
Thanks for answers!
Considering how many Honor/Huawei phones still got the Oreo update, I guess there is actually a fair chance we will get Android P. As for Oreo 8.1 ... well, it was already released for a while when we got 8.0 and as far as I know, the next "big" update with face unlock is still based on 8.0 so I don't think we will be getting 8.1 in the "near future"
Latest EMUI8 B365 with May Security Patch is still Android 8.0.0
Updating to 8.1 requires a kernel update as well from what i could understand (Honor View 10 as source code for the 8.0 and 8.1 firmwares separately, and the difference is the Linux Kernel version), so the update will depend on their will to make that update or just wait for Android P release and update directly to that one (My bet would be that they will leave it at 8.0.0 and update directly to P by the end of the year or so)
Has anyone tried booting a plain AOSP treble 8.1 ROM on the H9 yet, was considering it the other day, but not sure if its worth the soft brick mess...
likely we will get some sort of idea after face lock gets to every device
With Huawei/Honor it's easy to figure it out. Flagship devices get 2 major updates, and midange devices one. So we will definitely get P. Maybe with Treble devices they will increase it to 3 and 2 updates. As for 8.1, it's the same story as 7, they went with devices on 7.0 straight to 8.0

Huawei device "ptrace" implementation issue

Being a no good dirty cheater, I'm a big fan of Game Guardian and I use it with great success on my HTC U11 phone. I recently discovered that it can be used without root, by using a virtualization environment such as Parallel Space or VirtualXposed. As I haven't rooted my M5 (SHT-09), I downloaded Parallel Space and GG and got it all running. However, I've found that I cannot make any edits to game memory space from within GG.
The are a number of posts on the GG forum suggesting that there is a bug (or security feature) in many Huawei device cores / firmware that relates to the implementation of the ptrace system function call. Something in the firmware seems to prevent the GG process from modifying the child process memory space using PTRACE_POKETEXT or PTRACE_POKEDATA.
The suggestion of the developer of GG is to "change the firmware so that there the ptrace system call works normally".
Anyone aware of this "feature" of Huawei device firmwares? Is there / could there be a solution to modify the firmware to "fix" this behaviour?
I saw you posted on my thread. Thanks for that. I wanted to see whether flashing a different kernel like Serenity would help. But i doubt it. Might be worth a try. Would have loved to know that beforehand. :/ Any other ideas? What I am seeing is that it needs a competent developer to recode the Kernel. I would then flash that patch. Other than that it is defined as unfixable. That we'd have to change the device. :/
It's the main reason that I haven't rooted / unlocked the bootloader, as running GG is pretty much all I use root for on other devicxes. And the fact that rooting / boot unlock kills Widevine level 1 support, which is madness on a 2k device like the M5. Wouldn't want Netflix streaming SD content only.
From what I understand, which isn't much, the issue is buried deep down in the kernel. Not sure if a custom kernel would solve the problem or not. Knowing XDA, I'm sure someone will be crazy enough to try it at some point in the future!

Yeah I get that, but some games dont have a cloud feature. Making parallel space useless. Plus I appreciate some other root features. I have a note 8 which should work GG without root, but I'll see how it goes. Oh really, I'm a big time stream fan. I havent tried Netflix with root yet . Should still work tho. I think. Hmm well, problem is all kernels are made for devices like the mate 10 or the P20. Not sure if they will work with the M5, wouldn't want to brick after all the trouble. [Edit, found the nextflix module apk. Can flash that with Magisk. Makes it work again ]

Alright guys, I found this out today (I'm also Kr1msonReaper on GG forums);
Huawei kernel prevents GG from working in Android Oreo HOWEVER-- If you downgrade to Android Nougat, I find that it works perfectly. Hope this helps!
Just a note, when you are, of course, debloating Nougat, make sure to disable Huawei system update app so you don't find yourself in Oreo the next day.

How do you downgrade to nougat? Any reason not to do it? And will I retain root ?
I actually like Nougat more than Oreo as it fixes issues such as the ptrace error and seems to have more battery optimization. It's been a long time since I downgraded to Nougat and since then I got a new phone but here's the tutorial I followed. @mrmazak has helped me out of se sticky situations and his tutorials have never failed me. https://forum.xda-developers.com/honor-7x/how-to/guide-honor-7x-flash-oreo-update-t3781649/amp/
I believe you will lose root but you can easily flash magisk again after installing the downgrade package.
Hope this helped!

I am not sure this would work on the Huawei mediapad m5 tablet. As far as I can tell it never had a nougat firmware to rollback too. I looked for sht-w09 and the all the files appear to be for Android 8 and none for 7 nougat. Unless I am missing something??
Other than they locked out ptrace stuff and that it appears unlikely to get Android 9 in the US for my mode l its a pretty good tablet. Maybe I should just sell it and move on to a tab s6 that can be rooted.

Hey! You're right I couldn't seem to find a nougat downgrade. On the bright side, I did find a Pie update for your model. Who knows, maybe ptrace will be fixed in that version?

Good luck!

How can I downgrade my Android 8.0 to 7.0? (Mate 10 lite)

Hey,
Altough I bet there are hunderds of threads like this, I decided to create another one
So because I have my mate 10 lite around 2 years (a bit less), I would like to get an upgrade. Sadly I won't get Android Pie officially, so I'd like to install a custom ROM.
To do that I need an unlocked bootloader which dc-unlocker is only able to do below Android 8.0.
So I would have to downgrade my Android 8.0 (Btw, EMUI is also 8.0) to Nougat 7.0.
The method through HiSuite didn't worked since it just says "Newest Developer Version installed", but nothing with "Switch to other versions".
Also through Firmeware Finder (Playstore App) it doesn't show me the option "In-App Proxy", so I guess it doesn't work either with that.
Is there another way to do, if so I would really appreciate any help
Thanks in advance
My Mate 8 also keeps on Android 8.0, without any update to Android Pie officially.
If the official utility, HiSuite, which is developed by Huawei doesn't work, we maybe have no way to downgrade the system software on Mate 10 or Mate 8.

It all depends on your current build version. If I remember correctly the ability to use DC was patched in most custs in May or June. So if your security date is prior to May you can still use DC. If not you're out of luck. You can use testpoint to flash board software and then get unlock code through there, but it requires you to remove the back of your phone which will break IP rating and void warranty (If it's still under warranty)

Question Poco M4 Pro won't update

Got a Poco M4 Pro 4G about a week ago, after initial set up stock rom updated to 13.0.1 (SKEEUXM). I see there are newer versions but several days later no update is available?
I am desperately looking to update or even downgrade due to a poor light sensor performance - in low ambient light and with auto brightness enabled the screen gets way too dark (sensor goes to 0 lux, when in reality it is not that dark). In a well lit environment it works adequately. Someone mentioned in another forum that after updating, they got rid of the issue.
That (V13.0.1.0.SKEEUXM) is currently the most up-to-date Android 12 firmware for the EEA. I think you could switch back to Android 11 (and a more recent firmware update) manually by unlocking the bootloader and flashing a fastboot package, but it's pretty hands on. Otherwise all you can do is wait for Xiaomi to update their A12 firmware.
Thanks mate, that means my updater is working fine then. I am tempted to go down to android 11 and a more recent firmware really, the sensor is acting terribly on the current one but it's still blind hope that would resolve it.

No , it is not true. The last update for EEA is
V13.0.10 RKEEUXM...
Sorry i didnt see. Yes you are right. With Android 12.
