I thought about the fact that it is you who can transfer other firmware to this device. As a developer, let's say.
On the F1 already installing the firmware AOSP, LOS and other projects. But need to flash these firmware through TVRP recovery. For our device, there is no such recovery yet.
I have little understanding of the intricacies of the android. Sorry if my questions seem silly.
If we take the firmware for F1, for example AOSP, will it have to be somehow changed for our UD Power? Or can just take the archive, as it is, and flash it?

The processor of our smartphone is not very strong, so it is not for games. It is also not clear what RAM is installed. It looks like the manufacturer has installed a cheap part. Put single-channel LDDR 3. So he made a low price. At the expense of device performance.

I definitely consider myself to be a major noob with the more advanced Android development stuff. I only know enough to find my way around the internet and flash compatible software, haha. I've never looked into creating ports myself, but it's certainly something I think might be worth learning, especially with the limited device support on these phones.

And yeah, in terms of performance I don't expect much out of a phone at this price point, but for all the essentials - music, 1080p YouTube, web browsing, and mid to light gaming, it's surprisingly great considering the price. I haven't had any issues with the memory as of yet, so I wouldn't be too concerned, although you're definitely right in that they probably source some pretty cheap parts for these kind of phones.

Glad to hear it worked for you!

Still nothing. Unfortunately I haven't had any luck with booting into TWRP since I last tried it. Hoping ghost45 will be able to help us out with that when he gets the chance.

I can only get the phone to boot using the stock recovery.img. Any modifications to the recovery causes a loop.

On the other hand though, I was able to get root through Magisk (I'm using the latest 19.3 version), and patching the stock boot.img through the app, then flashing the patched boot.img to the phone with SP Flash Tool. I have Viper4Android working, which was my main reason for wanting root, so I'm satisfied for the most part. Can't wait to try this phone out as my daily driver!

How do you manage to work Viper.

Cause i'm having some problems, tested all versions and my Driver always stays on "Active: NO Format: Unsuported.... Abnormal"

BusyBox also don't seens to work.

:/

Some help?

The trick to getting Viper4Android to work is to make sure you have SELinux set to "PERMISSIVE" rather than "ENFORCING" on your phone. Here's a handy little app designed to automatically set it to permissive on boot!
https://forum.xda-developers.com/dev...1561#downloads

And for BusyBox, I was having issues too at first because I think with systemless root, BusyBox can only be installed in /sbin, which gets wiped after each boot. So I searched for "BusyBox" in the Magisk app and found a module called "BusyBox for Android NDK" which has worked perfectly for me.

One thing to note...
Sometimes SELinux doesn't always get changed automatically everytime you boot up. It's pretty consistent, but every once in awhile you may need to manually set it to permissive mode again if things don't seem to be working. But it's literally just pressing a single button, so not a big deal.

The other thing is with Viper itself- At times when I launch the app, the driver status says "abnormal" even after I've toggled SELinux to permissive. If you go into settings and toggle "compatibility mode" or "attach audio effects" on and then off that seems to refresh the driver status. Not sure why, but it works.

Let me know if you have any issues.
