Hello! How to upgrade already rooted g925I to rooted marshmallow? - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hello all,
I have a galaxy s6 g925I on 5.1.1 and am using Xstreo Lite version 2.4 and TWRP version 2.8.7.1.
I am wondering how to upgrade to a rooted version of marshmallow (preferably using xstreolite again). But as I understand it, the process is a bit more complicated than usual. Therefore, my questions is a simple one: how do I so keeping into account all the new steps (updating the boot loader, updating TWRP version etc).
I tried searching but could find nothing that compiles all the information or says it at one place (or I might just be deficient in searching. Apologies in advance!)
Thanks so much.
Cheers!

Hi! Thanks for the reply. But if I do this won't I lose my root? Also will smart switch work with a already rooted phone?

Factory image of KitKat update

Hi everyone. ...I am not sure I am posting this in the right section and if I am not I apologize. This may be a long shot but I had just acquired an RCA 7 Voyager II tablet Model # RCT6773W22 and it came with Lollipop 5.0 preinstalled on it and I cannot get it rooted at all. I tried pretty much every method I'm guessing because it's a fairly new update and no one came up with a workaround for it to root it. So my request is does anyone possibly have the factory image of KitKat 4.4 or earlier for this tablet and if not would anyone know a source where I can attain this image? Because I would like to roll it back to KitKat and root it because I know there are a few one-click programs that will root it with the older KitKat updates. And also another question I have is will I be able to use Odin to flash the image to the tablet or will I need to use another program or method? Any help will be appreciated. Thanks in advance.

Looking to Root, and install CyanogenMod

Hello everyone.
I am looking to Root my T-Mobile Galaxy S5 (G900T) phone. It is currently updated to Firmware 5.1.1 and the Baseband version is G900TUVU1FOG6. After I would like to install the most stable / secure version of CyanogenMod.
I looked at a few other topics on these forums, one being the compliation thread with all the roots , patches, etc but it says it is not possible to root anything with FOG6. (This thread: http://forum.xda-developers.com/tmo.../compilation-s5-g900t-stock-firmware-t3042400)
Is that thread still acurate?
Thanks in advance.
Edit: Also looking to get a good recovery to make this process easier.
Inaccurate/out of date. I had it rooted the day the kernel source was released

Few questions about changing roms [S6] Please Help

Hi,
Details about phone: Samsung S6 (G920I) I can't remember the exact ROM im on (yes im a noob). However my build number is LMY47X, which when searched by most views comes up with this rom (http://forum.xda-developers.com/galaxy-w/development/rom-aosp-alpha-1-t3107740) Android version 5.1.1 I have TWRP v. 3.0.2-1 as my custom recovery.
So my phone keeps restarting randomly been getting worse over the past few weeks. So I want to try a new ROM (had my current one for like 8 months). So I made a ROM back up just in case through TWRP and backed up all my user data through Titanium and exported both of it onto my PC.
I found a ROM I want to use "XtreStoLite" ( http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-0-t3094423) but I have a few questions before I try to install it.
First of will this work fine for the current setup I have?
Since I'm on 5.1.1 and they have a ROM version for 6.0.1 will I be able to install this version or do I have to use the 5.1.1 version? I've tried updating to 6.0.1 on my current ROM but my provider won't let me update OTA. Only way is to remove root and return it back to the stock ROM which I don't really want to do if I can avoid it.
Please help, any information will be greatly appreciated, feel free to ask any questions.

This ROM will work for your device. Based on what I read in the OP's post on how to install this ROM there are two prerequisites. You will need to use Odin to flash a Marshmallow bootloader and a Marshmallow modem for this ROM to work. This is an excerpt from the ROM's OP:
How-to Install:
Install Marshmallow bootloader & modem and install custom recovery:
- Install the correct MM bootloader & modem for your model with Odin (see post #5 of this thread)
- Make sure that you have an working TWRP custom recovery installed.
If you follow the OP's instructions you should not have any problems. Make sure you read, read and read. The OP has given an excellent guide. Post #5 in this thread has the download links for the Marshmallow bootloader and modem and instructions on what slot to put the files in using Odin. Good luck and happy flashing.
Also, if you wanted to stick with a Lollipop ROM the OP still has links to his Lollipop ROM's available.

Newbie help with updating while keeping root

First, I had a rooted G3. Never updated it. Now, I have an H830 (T-Moble) variant. I've been rooted since I bought the phone and have never updated because I don't know how to do it without losing root. I'm still on software version H83010d (Android 6.0.1).
From what I've gathered, I just download the .zip in here and install via TWRP and then flash superSU afterwards?
I'm not completely sure what the talk of modifying boot.img or removing recovery-from-boot.p...
My reason for updating is because I want to try the Fulmics ROM or any optimized ROM for that matter. I had one on my G3 and it ran so much better.
But then as a follow up question, is the update process the same from a ROM? Do you just flash an update over the Rom and then re-flash the ROM?
Any links or answers are appreciated so I can finally figure out how to update while retaining root on my devices. :laugh:

G925F BTU - Android nougat to marshmallow

Hi,
I've been looking for an answer to my question, and I think it's been catagorically answered - you cannot downgrade from nougat to marshmallow mainly because the bootloader needs to be downgraded.
I desperately want to get back to marshmallow as nougat broke a certain app that I use all the time, and the app is no longer being maintained.
I currently have SuperStock S8 ROM installed on my G925F. Before I rooted and installed this, it was running the official OTA Samsung Updates available in the UK (my phone is BTU). This firmware would have been this one here - https://www.sammobile.com/firmwares/galaxy-s6-edge/SM-G925F/BTU/download/G925FXXS5EQL6/202020/
Now my question is can I downgrade to marshmallow at all? I mean, even if it's an unofficial ROM which requires root (preferable). Because I think the main reason the app I'm having difficulty with has stopped working is due to the bootloader or modem... Possibly. I don't really know what I'm talking about.
Any help is greatly appreciated, and apologies if I have left out any relevant info required to help provide an answer.
Thanks in advance.
