Downgrade from Android 10 to Pie possible? - Samsung Galaxy A10 Questions & Answers

Hi
I've ordered an A10 for my wife. If it comes pre-installed with Android 10, can I downgrade it to Pie so I can install a GSI rom from @phhusson?
TIA

If they are the same bootloader version, you can. If not, you can't. If you don't know how to tell what bootloader version you are, I suggest you use Google.

Thanks for the quick reply but now you've really confused me! If the phone arrives with Android 10 on it what am I comparing against? And if it comes with 9, is there any way to check the bootloader version of the 10 upgrade before I install it (don't want to be stuck on a version I cannot root <g>)
I haven't had a Samsung for over 10 years (S2 - fabulous phone) so I'm a bit out of date. Is the bootloader version still the 5th character from the right in the baseband number?
TIA

Well, first of all I don't know if Android 9 is available for your phone or not lol I don't have the device. Maybe it does, maybe it doesn't. I suggest looking at sites like Sammobile to see if there is Pie for your phone
And second, yes that's how you can tell the bootloader version on Samsung phones still

Thanks @ShaDisNX255
Good news - it came with Pie not 10 and the bootloader is v3 so I should be good to go

Miui 8 China Developer Rom Based On Android Nougat 7.0 Available?

Hi there,
just wondering whether we finally got Android 7 for our device? According to these threads it should be the case:
https://xiaomininja.com/2017/02/11/...i-8-china-developer-rom-7-2-9-is-rolling-out/
https://www.getdroidtips.com/manually-update-redmi-note-2-miui-8-v7-2-9-android-nougat-2/
But I am currently using MIUI 8 Global 7.5.4 Beta which is still Android 5.0.2 - maybe this is due to not being developer ROM.
What I do not understand is the flashing guide from 2nd link: Do I have to install both versions? Recovery and Fastboot? And does anybody already have this ROM in use? Can it be just flashed over Global Weekly Beta?
Thanks for your responses!
Bye
have a try? Is it really Android version nougat?
@Renth You have to post this in original developer thread when it is just a noob question? It is completely fake news - don't post this crap here.
@jajk: Ok, then some mod will have to move this thread (or can I move it myself?). My knowledge also has been that there is no Android 6 resp.7 for RMN2. But why do you think it is fake?
Even MIUI Germany talks about it here.

We will not get Nougat or even Marshmallow officially ?
I admit the list is somewhat confusing since it also says:
Aktualisierte Geräte : ... Redmi Note 2 ...
Click to expand...

=> Which means updatedd devices and:
Optimization - Android N update (02-20)

I admit it might mean that all listed devices got some updates but not all of them received Android N (was really suprised and could not believe it myself). Anyway I asked within the changelog thread.

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)

Can you root Huawei Devices?

I seen that rooting gives you more acces to your phone and a lot of things, my device is a P30 Lite MAR-LX1A and as I saw you need to unlock the bootloader to root it. My device is working perfectly fine but I have some small isues about it, so shortly, I'm asking for help if anyone knows about it, if I can root it I just want a short tutorial on how to do it and the correct links I have to get because there are a lot of indians on youtube there and I don't trust them.
What Android version are you currently running?

Follow this DC-Unlocker guide. Remember to click the link with instructions on how to put the device to test point mode! This is the only way I know how to do it.
Remember that DC-UNLOCKER is a paid service!
This is how to unlock the bootloader. Because you are on Android 10, the bootloader might re-lock so it's recommended to downgrade to Android 9.

Download the firmware from here. It should match your device. If you have a spare micro SD card it's the easiest way to install the firmware. If that's not an option for you, there are other ways mentioned in that same article that will downgrade the firmware, too.

[Solved] Unable to unlock bootloader with ANE-LX1

Hello, i've just got a Huawei P20 Lite ANE-LX1 with EMUI 9.1.0.381 from a friend. It's my first Huawei and since i am usually running my phones with custom roms, i want to install a custom rom to it. Usually i am trying to get phones that have a reasonable unlock process but this was a gift and i thought it should be possible to install something anyways.
After spending hours into this and reading allot of posts on this forum, i am not eager to open up the hardware and go this potatoe way. I've watches some Youtube videos about the process and i am not sure, if i can manage to get the phone back together. So i was trying the other way with downgrading EMUI to 8 using dload method in order to run dc-unlocker. But somehow i am unable to do so. I am always ending up with "incompatibility with current version" error. I've tried using the dailer code menu, as well as the 3 buttons method. It's not working at all. I've tried multiple versions from androidhost.ru for this phone. There were no options to downgrade to any prior version using HiSuite as well.
Can someone help me to unlock the bootloader for my phone?

If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower EMUI 9 build version number doing the dload method (flashing Service ROM ). What is your region? (Cxxx in build number).
Btw, it's impossible to downgrade to the lower EMUI version via dload method.
Hello, thanks for your reply. My current build number is C432E7R1P7. I think i figured that i should use C432 versions but i haven't thought about using another 9.x version and instead go straight to 8.x. Is any lower 9.x version ok?

On EMUI 8 (in order to run dc-unlocker) you need downgrade to .126:

With .126 you should be able to use dc or hcu-client .
Thanks, you've helped me allot! I've got it working and have the bootloader unlocked. Going forward, i was reading your LOS 17/18 thread. I could add a comment there but since we are writing here now, i am going to ask here:
I am still with EMUI 8. Is it actually needed to install another version of EMUI in order to install LineageOS? Isn't it possible to just install TWRP and go on from there?

LOS/LiR requires emui 9.1. Do not install the latest version, flash 9.1.0.200 via dload.
Finally made it and finished installing LOS. Thanks again for your help. I've marked the thread as solved.
No problem .

The latest update you can get is Android 9
If you are not able to recieve OTA updates, you may need to flash KDZ of Android 9.

Thank you tech_infinity i was so lost by this, especially being that at one time this was considered one LG's flagship phones, lol, well im trying to figure out the best way to root it,and what root to use , because it is really nice and i love it , it does strike me a lot at factory set up to be like the galaxy s10 or 9 note in some ways but in really want the thin Q 50 or 60 Q im very interested in , are they quality as well like this when this came out ? or ....
To root the phone, we recommend using the WTF thread and the instructions detailed here: https://forum.xda-developers.com/t/...ar-instructions.3790500/page-10#post-76584629
