Downgrade from 5.1.1 to 5.0.2 ! What's the worst that can happen on a Live Demo Unit - Android Q&A, Help & Troubleshooting

So, I have an S6 EDGE G925X live demo unit... and after trying everything i could find on xda and internet i couldn't make it use a g920F rom so now my only option would be a downgrade. Taking into account it's a demo what would be the worst that could happen ?

You should not downgrade the Android version without a full wipe. If you install Android 5.0.2 over 5.1.1 your device will not boot I think.

Help with Rooting and Installing Cyanogenmod on S6 Edge G925I

The title says everything. The last time I tried to root a device was the 2012 Nexus 7. It was very painless with that device, but that's to be expected with a Nexus device. As of right now, I'm very confused as to how to root this S6. I am on Marshmallow 6.0.1, with the G925I variant of the device. I don't care about voiding warranty or not using Samsung Pay, as it seems Samsung doesn't want to release that for the G925I variant.
Hopefully once I get root and install Cyanogenmod I can get much better battery life, as right now Google Services is taking up >40 percent of my battery and I have to charge a couple times a day. I have tried everything I can think of, but I figured screw it.
TL;DR: Basically, can anyone write out a step by step procedure for getting root and installing Cyanogenmod on an S6 Edge 6.0.1 G925I?

Unfortunately Cyanogenmod doesn't work with the S6 Edge (or S6) some devs managed to get it booted but couldn't get much further thanks to samsung's closed source
http://forum.xda-developers.com/gal...development/cyanogenmod-13-galaxy-s6-t3269984
your best bet is to root and flash a rom of your choice, install Xposed and tame Google Services with Amplify
And why would anybody care about cm for the s6?? It's more or less a preview of something that'll never be. If your out for aosp roms you bought the wrong device

Is your phone completely stock? Have you flashed anything else before, like a custom ROM and then went back to stock or are you still on a custom ROM or anything like that? Or is your phone still the same as when you unboxed it?

It sounds like you might need your local carrier's CSC, but that would be from the snapdragon model not the exynos one that you have. Meaning that you would likely need to root your phone and either change CSC by flashing a custom rom with CSC selection option, or flashing a standalone csc-switching zip. These methods would allow to use a Snapdragon CSC on your Exynos, and likely provide the features you want.

Thanks I really appreciate the help it looks like im going to try and root my phone seeing as i have an international model and samsung US doesnt provide warranty for it anyway because of such. I originally bought the phone from RAC because I work there so my discount was nice and I just recently got it completely paid off and was able to get them to remove there knox profile with out any hassle so no more rac system apps in my phone that just prevent you from doing a lot. Do you have any suggestions as far as where I should start I already have the latest version of odin downloaded on my computer but Ive never done this before Ive only recently started picking up an interest in development.

Look up odin for s9 and a pc based program called frija. It can get your latest firmware fast.
It's quite simple. You have to download your phone's firmware first.
You can do this with a simple google search. There are pages like Sammobile, Samfrew and others. Though I would honestly suggest Frija (PC software) as it can download firmware faster than any website I've seen.
After that you just flash it with Odin, there are plenty of Youtube videos on how to do it. It's quite simple, just extract the firmware and flash the files AP_, BL_, CP_ and CSC_ (there is also HOME_CSC which will update your phone without wiping data, flash HOME_CSC instead of regular CSC_ if you have photos in your internal memory that you have not backed up)
And you should be updated

[No Root] Samsung Experience 8.1 on S6/edge

Hey guys. I know maybe some of you guys already did that years ago and that I am pretty late with it right now but I havent seen a thread where this was mentioned in (maybe I was just too lazy to look everywhere) but I recently made a video on how to get the Samsung Experience 8.1 Features on the S6/edge without any root or custom rom. Originally, we only got Experience 8.0, according to Wikipedia, however it isnt even mentioned in the Device Info page (if you ask me, they should have waited a few more weeks and should have given us Android 7.1.1 directly like the J5 2016 or SE 8.1 with 7.0 like the S5 Neo).
However, thanks to API 24 / Android 7.0, we are able to get nearly 80% of the Samsung Experience 8.1 Features, by updating the stock apps and TouchWiz Launcher manually. We can even get Bixby Home with that method. Things you will not be able to change are the general look of the UI (Lockscreen, Settings, QuickPanel), however you can install AOD Display, which will then be shown in the Settings. S6 edge+/Note 5 users will also benefit more from this, as they already got some S8 functions inside their firmware like changing Screen resolution or being able to activate Boostmode. The tutorial should be applicable to every Samsung device that runs Android 7.0 (A-2016 series/J-2016 series)

No. Please only use the versions I linked in the video. If you install a more recent version of TouchWiz/Bixby, they might start to crash. You can try though

General [Info] Samsung Galaxy Tab A7 Lite

See:
Samsung's Galaxy Tab A7 Lite has leaked once again before launch
The upcoming Samsung Galaxy Tab A7 Lite has leaked once again via unofficial press renders that have been shared by Evan Blass.
www.xda-developers.com
I love the tablet, bought two of the 4GB/64GB for $149 each directly from Samsung site.
Well worth the money, I got them for gaming and watching videos, web surfing, really great tablets.
Can this tablet be rooted ?
Good

Impreza thank you for making me rest.....I've been surfing online finding answers if that tablet can be rooted...please let me know if you guys found more info..thank you
Bought this thinking it was an upgrade from my Galaxy tab a 8.0 but since it's one ui core it's missing many features. Trying to trade it in now but it's past the 15 days. There's no smart view to mirror to any tv easily, theres no network file manager in my files (can't access G drive or any others).
Just make sure you know what you're buying. It's not lite because of being smaller than A7, it's a stripped down OS and the features can't be installed afterwards (have tried many apks). I didn't want a big tablet, wanted a mid size tablet with upgraded CPU.

I agree with that. If you are sure you know what you're buying, the experience of the A7 Lite isn't bad. One UI Core is the same stripped down OS in the regular A7 (Snapdragon 662) and in the A7 Lite. CPU works very fluid if you tweak some settings (default One UI animations are awfully slow). Battery lasts A LOT (8,5-9 hours SOT). Smart View was removed and changed in all One UI devices with the upgrade to Android 11/One UI 3.0 (regular and Core), and it was replaced with Google Cast native screen mirroring (ergo Chromecast).
Use Solid Explorer or Amaze if you want to access network file places. It works well on my side.
Despite being a Mediatek tablet, you wont't find anything MTK-related in the tablet. Samsung has its software very well masked. And I think that, in Helio P22T, Mediatek vulnerabilities have been fixed with security monthly patches.

I guess that MTK-su has been fixed on Android 11... But I think that I could boot something with DSU Loader, which is available...

Just wanted to chime in here and say that I successfully rooted the tablet using the same method for the Lite as the regular A7 using THIS GUIDE. Obviously it tripped Knox but I needed it rooted for my use case. One note is that when you download the stock firmware with an application like Samsung Firmware Downloader, make sure you choose the correct Model and Region. These can be found in the settings on the tablet.
Is it possible to enable Google Discover for default launcher?
I bought Galaxy Tab A7 Lite LTE SM-T225 3/32GB and it works quite nice. Small and good device. Would be cool to see on it clean Android or LineageOS (fingers crossed). There is not too many ~8 inch tablets today with the latest Android version.

I've been working on porting TWRP for AOSP Android 11 to this device but have run into some roadblocks.
I currently have TWRP running but touch is not working and I can't seem to get Data R/W with the current tools available. It's possible it's an error in my build or maybe a workflow problem.
If anyone out there with more experience is doing the same or wants to help me sort some things out, please let me know.
I purchased the SM-T225 LTE 4/64GB model, a good device, but there was a problem on the latest T225XXU1AUH5 & UI3 firmware, specifically with a modem... after the end of the call, the mobile network disappears, and after rebooting Baseband Unknown Flashing does not help, only resetting the data helps, but before the next call... The device had Root rights, but is now installed stock firmware and blocked the bootloader, but the problem remains... At the same time, if you install the old modem UDA,UE3,UF2 , it works without problems... Has anyone encountered anything like this?
My only disappointment is that knox is included. I came from tab A 8.0 2019 which has no knox

Bought one earlier today for a second screen for browsing while I'm gaming on the laptop. Got way more than I expected for such a cheap price. Debloated and tweaked, I really can't complain.
