Administrator OS - Samsung Galaxy A20 Questions & Answers

Hello all, I bought a job lot of Samsung phones, including an a20 that has an Administration OS installed onto it. Can I just flash OS via root, or will I need to get in contact (hopefully) with the issuing company of the OS?
Thanks

I t would be even great with a good instruction how to install it on the tablet.
Can somebody guide me in the right direction..
King regards,

You should really do some searching - the search function will be your best friend. Assuming you are rooted and have a custom recovery installed, I would recommend installing AOKP from this thread and giving it a try.
Again, I would do some searching and READ A LOT. Not everyone is kind when it comes to random posts spamming up the forums.
:laugh:
Well aokp it's a really good rom but you should take into account the fack that the camera it's not working on any ics rom at the moment.
As for your question about the apps i find out that the best way it's to make a cwm back up and then using titanium back up pro (you have to spare some bucks) restore the apps + data that i want from the back up. Also you can make the back up using the free version before flashing the new rom.
Cheers!

I have a rooted SM-G928F.
I hope this thread is in the right category.

Make custom rom with vendor files

Hello,
HTC having obviously stopped supporting my smartphone in terms of updating android, I want to create a custom ROM to enjoy the benefits of the later versions of android in Mashmallow.
However, HTC provides the source code of the linux kernel used as well as some tools necessary for the proper functioning of the device. In addition, it also provides a guide to compiling android. Unfortunately, this guide seems incomplete or poorly explained. So I would like to get help in compiling an android rom for this device.
Please do it. unfortunately I have bought this device recently a month ago and feels like i have been cheated by HTC!! No proper support no software or security updates and really poor website with no useful data to end user, it seems that the company produced this model and dumped in the market to get our money and forgotten or ignoring users with at least security updates, even the non branded Chinese phones get better support than this brick from HTC. My first HTC phone was windows mobile on 2008 , it was poorly supported and my bad luck again with HTC u play which has the same situation. I will never buy from this company again.

Yoga Smart Tab

Hello,
So I got a Lenovo Smart Tab (yt-x703f) and really want to flash TWRP to it, so I can flash LineageOS rom, but it seems like there's no support for it, or even a subthread on XDA.
(I tried various twrp images)
Anyone got some experience with that tablet and have something working?
Cheers
For some reason this device gets the silent treatment on all fora. I can't figure out why, this could be a great multimedia device with some adjustments. batt life is great as is the sound. Screen is ok ish and the speed needs to be tweaked, but no one is willing to tweak
You can root the device and even flash a GSI on it. Tested myself and everything is working
Yoga Smart Tab - Iron Grey​Part Number: ZA3V0005US
Not sure if we are talking about the same device but lenovo does not support their mid tier devices with OS updates and would like to install a bloatless OS also pie is really dated and wondering if i will run in to issues with app compatibility. There is also that issue where it won't run HD in netflix because netflix is a static app and can not be removed and reinstalled. Hence bloatware and would love a clean google experience.

Flashing a GSI might help if the device supports Project Treble. Basically any device launched with Android 8 and above should support Project Treble.
Hi, I have a Lenovo Yoga smart tab (YT-X705L) and I want to install a new rom on it. I’m not an IT wizard so I need help with that. Would you find anyone who can give step-by-step instructions from start to finish with download links.
And if you can find experiences on how anything works (which is GSI). Thanks in advance.

Galaxy S8 [SM-G950F] Kali Nethunter

Hello, does anyone have a compiled kernel for Galaxy S8 Exynos [SM-G950F] that supports HID and External network card? I need to equip this phone with Kali Nethunter.
Looking for some compilations I came across something like this:
https://gitlab.com/kalilinux/nethun...tree/171563c6970e65c4a1ff71eaeddb303cde5f0f89
This is the first time I'm dealing with kernel compilation, and creating installation zip package.
So my questions are:
1. has anyone already installed Nethunter on this device?
2. Is there any hardware limitation on this device that prevents it from using HID and External network card potential (e.g. Monitor Mode etc.)?
3. If the hardware on this phone can handle it, can the resources in the link I sent above handle it all?
4. if the link I sent doesn't help, is there anyone who has a kernel and TWRP installation package for this phone, so that everything I mentioned above works?
I apologize in advance if my questions are incorrect. My experience in modifying Android is limited, as so far it has been based on thin modification of roms prepared by other developers.
Thanks!
Have installed nethunter store on g950v flashed to g950u. Rooted with magisk system root..... bootloader 8 [ yes locked bootloader].. nougat .....
Installed privelege escalation extension in the store and converted to system app with an app from playstore..... I know that's probably not the right way to do that but it seems to have worked fine and I'm not sure where to find these ota zips.... new to kali and only a linux novice......
Would love to figure out the right way to get chroot installed.and the full kali kernel\rom overlay...
Can anyone tell me if this is even possible on thia device ? Or would it break my system ?
If its possible can anyone tell me which ota zip I need to flash in safestrap{twrp} . I see a precompiled kernel for the g950f and I, wondering if that would work? And if not whay would be the proper procedure for installing kali on my device ? Any pointers or advice would be greatly appreciated.
I've opened the nethunter manager app and tried installing with the default settings but I get an error.
I'm thinking I may need to change the install directory but again I really don't know where I should change it to.
I love tinkering with my samsung devices and would really like to play around with kali if I could get it properly installed.
I understand that functionality may be limited on my device since there doesn't seem to be anything posted online that I can find about kali and the g950u.
I guess the locled bootloader tends to make people shy away from the snapdragon devices.
This is my 2nd s8 and its still a great device after all these years. I would
love to see some renewed interest in this device and hopefully with kali or any custom roms other tha. The basic nougat with gapps...
