Hello!
Here is the full G925VVRS4DQD1 Odin manual update to 7.0 Nougat for everyone to enjoy. You can flash from any current version you have now it doesn't matter whether you are on 5.1.1 or 6.0.1.
https://www.androidfilehost.com/?fid=529152257862722630
If for whatever reason you want to downgrade or don't like 7.0, you can safely downgrade to any of the below versions without any issues. After you flash a lower android version using Odin, phone might get stuck on Verizon logo. If that happens, all you need to do is boot into recovery and do a factory wipe/reset and phone will boot right up after that.
G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500

Thanks a lot! I downloaded one from sammobile but there was one only one file, modified date 4/07...
I notice the files within the zip from your link mention REV02 and are dated 4/26.

@toutanje Out of curiosity, how did you determine which builds you can safely downgrade to from 7.0? Is it something you personally tested or did someone recently go through the hard work and post their results somewhere? BTW, you can now add G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500 as two people have confirmed downgrade success here: https://forum.xda-developers.com/verizon-galaxy-s6-edge/help/downgrading-nougat-t3601096 . One used firmware from sammobile and the other directly from the link above. This is the very last build available for Marshmallow.
Hi there. I installed the new update on my s6 edge 7.0 via verizon software updating tool.am noticing the sound quality of mt s6 edge has been changed.before the sound quality was thick and now its not that thick anymore.i want to bring back the thick quality sound on my s6 edge.there is setting called sound quality and effects but i cant manage to get back that sound quality i had with 6.0. Is there anyone who able to notice this change in the sound?

With a very a simple observation, no testing or anything needed
G925VVRS4DQD1 <-- you see the 4 towards the end of firmware build? That is the revision bit number. This means you can flash ANY firmware for that model with a 4 or higher. Take this 5.1.1 firmware for example ---> G925VVRU3BOG5. Even though this firmware is also 5.1.1 like the ones from above, this particular one will NOT work because it is on an older firmware revision bit (3).
The same is true and goes for ALL Samsung phone/tablet models and firmwares.

That is very good to know. Yeah I noticed it about the firmware naming convention but I had no idea what the value means (or the character before revision bit, U has become S). My phone out of the box was on G925VVRU3BOG5, so I guess I could go all the way back to G925VVRU4BOG7 if "needed" lol.
One of my fears about Nougat is about all the work they did to automate and place updates into the background. This could allow disabling of downgrades, or anything else at the discretion of Samsung and/or the carrier. I think this has already been done in Marshmallow, just on a smaller scale for security fixes. Anyway, it seems to me like an attack vector waiting to happen: less control over my phone combined with an easy way to break things. Imagine all the troubleshooting fun we will have.
So I upgraded to nougat. I'm having battery issues and just want to go back to marshmallow. but I'm having problems. The nougat rom installs just fine with odin. But when I try with any of the 6.0.1 roms it was failing. Then I noticed that re-partition was chcekd. So I unchecked it and now it goes through the process just fine. But now the complains with dm-verity verification failed. I can install nougat on it no problem. It's just the downgrade that's not working... any clues?

I actually managed to get the N925V to downgrade all the way back to the firmware version G925VVRU3BOG5.. May have cost some money for some very specific files but my phone's back on G925VVRU3BOG5 and it's really only a test phone for someone I do work for! I have it rooted with SuperSU and not kingroot and I created a script to keep the phone set to "permissive" so it's able to do full reboots and not just hot reboots using xposed... Unfortunately it seemed like no one cared about it when I posted it in the other thread so it's probably not worth it to a lot of people but I think it is with the amount of fine tuning I did to get it to where it is today!!

Mike! Can you explain how you did it? I'm stuck on nougat. Every time I try to downgrade, I get the dm verity error. I've tried all the 6.0.1 version and the 5.0.1. No luck . I'm back on nougat. Can you please let us know your process... Thanks!
Did you have to select anything special in the options? I just left it at default which is Auto reboot & F. Reset Time.

I mean I could but I had to shell out some money for this firmware and I don't even know if you can flash it with odin because I don't use odin I bought a box to do my flashing since I work on so many phone's and odin just doesn't cut it.
No Worries. Finally figured it out. Good luck to you

I was able to use this to flash my Samsung Galaxy S6 Edge from 5.1.1 to 7.0.
Not that I want to upgrade again, but is there a 7.1.2 available? Is there a routine schedule for that sort of thing or was the 7.0 Nougat think kind of a special case?
Thanks!

I haven't been keeping up, but now curious. Verizon shows DQH1 as current (a 7.0 build), while sammobile and androidfilehost show four builds available (all 7.0).
Ok, so I updated my G925V with nougat, now I'm just wondering if anyone has come out with a way to root this build? That's what I'm waiting for. Plz fill me in when that happens. Thanks.

I use the Z3x box and Octoplus box I have 2 of them for different phone makers but I have so many different wire connectors that I lost count because what works on Samsung doesn't work on LG, HTC etc etc.. You can find them pretty cheap but I'd avoid buying from eBay because of to many scams selling broken or bad boxes that can't be activated.

You unfortunately cannot downgrade the bootloader once you updated to 6.0.1 you lost the ability to go back and there's so far, no way possible to do it.
Hi,
about 2 years ago I rooted my S2 Galaxy Tab (T719) and now I would like to upgrade from Android 6.0.1 to Android version to 7 or 8. I have googled for instructions on how to upgrade a rooted S2 Tab but did not find anything useful (most info is on OTA upgrades which no longer works on rooted devices). Could someone please post step-by-step instructions (please bear in mind that I only ever deal with this kind of thing once every 2-3 years so I do not have much experience). I have TWRP v 3.0.2 installed (do I need to update this as well?) and the tablet is not encrypted (so hopefully I won't have to wipe the system partition and re-install all the app?!?). Thanks.
I also noticed that there is now a huge variety of ROMs out there. How can one know which ones are trustworthy? The main reason I rooted the tablet was to be able to increase privacy (control app permissions with XPrivacy). So I do not want to install some custom ROM that maybe contains spyware or other compromising features. Any advice on this would be greatly appreciated. Given my motivation (privacy) for rooting, would it maybe be better to go back to Stock ROMs (i.e. non rooted) and simply control web access via netguard (by preventing net access for some apps, they may still spy on my contacts, location, or email but cannot phone home to transmit the information)? At least I would still get OTA updates because being excluded from the OTA channel also poses a security risk in itself I suppose. Ok so any advice would be appreciated.
Thank you in advance!
There is no official Android 8 for our device. If you want 8 or 9 you have to install a custom ROM like LuK1337's LineageOS port. It is as safe as LineageOS is by itself on any device. Only problem you might have then is that calling is not possible anymore for now, but LTE works. If you want to use LOS, you HAVE to format data because it's not compatible at all. If you wanna stay on official Android you might keep it. Installing is done by flashing the official firmware with the correct country code over Odin. This will remove TWRP at first so you have to reflash it by Odin afterwards. For firmware download I always use: https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 and Odin is found by google. If you wanna got the way to LOS you have to do all the steps I mentioned before too anyways to have a recent Modem firmware and bootloader. In that case you just have to flash LOS and OpenGAPPS by TWRP and delete /data aka Factory reset.
Regardless what you do, after ODIN is done, you HAVE TO boot into TWRP immediately to keep it from being removed by official firmware. While you are in there anyways you can install magisk to keep it from encrypting /data
Many thanks emuandco. So I guess I will stick with the Android 7 as I do not want to reformat the tablet and reinstall all the apps. I have started to download the Android 7 stock ROM, but it is taking quite long so in the meantime just to confirm, the steps to follow are:
1- use odin to flash the stock ROM (no steps required prior to this? I simply overwrite the existing ROM? I suppose that I will loose root then and need to re-root the device using the standard procedure as explained here: http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html ?)
2- use odin to flash TWRP (I will need the newest version I guess and cannot use the same as for Android 6?)
3- boot into recovery mode to ensure that TWRP does not get overwritten
4- done
Is this correct? Do I then need to reinstall Xposed, SuperSU and Xprivacy or will they be preserved?
Thanks again!
P.S.: BTW, I also found these instructions: https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 which are slightly different from http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html and require a wipe of the data partition. Does this mean that for an update to Android 7 I definitely do need to wipe the data partition? If this is the case then this would be a major disadvantage of rooting in the first place and maybe I simply flash the stock ROM and do not root at all but go the "netguard" route as mentioned in my original message?
I never used the official Firmware that much. Fist thing I did was going on LuK1337's nerves to get a port of LOS for it up and running So no clue if Samsung manages to keep /data but I guess so. Yeah, looks fine what you list there. You COMPLETELY overwrite ANY modification in kernel or /system, so reflash your mods and root (Magisk). I always recommend to uase the MOST recent TWRP. (https://dl.twrp.me/gts28velte/ should be it in your case).
Ah and looking at your manuals... Check OEM unlock just to be rather safe than sorry if things go mad.

I am looking into updating my S9+ to Android 9.0. The Magisk guide suggests use of FlashFire which I've managed to get up and running on my device, but the issue I have run into is I am unable to get my phone to even download the OTA files required for the update due to Samsung anti-root measures.
I found a website ("firmware.science") which provides these OTA files from firmware x to y but only US phones ("G965U" for the s9+) seem to be supported by the website.
Is there per chance any way trick to download these files elsewhere? I ran a debug on my phone and scanned through the logs to see if my phone was connecting to the update servers in the background but no luck. For the reference my current firmware is G965FXXU2BRJ3.
Thanks in advance.

Why not just flash pie and then reroot cause even with flashfire it doesn't flash protected partitions the bootloader or modem so your wifi and baseband would of been broken anyway

Hello,
I have a Japanese Galaxy S10+ Snapdraon branded for au
CPU-z information: model SCV42_jp_kdi - CPU Qualcomm snapdragon SM8150 8 cores - GPU Adreno 640 - Architecture Kryo 485 - screen 1080x2280 - board msnile - Brand KDDI - model SCV42_jp_kdi
Model number in About phone is SCV42
Model number on box is SM-G975
Bootloader: SCV42KDU1CUD4
Build Number RP1A200720.012.SCV42KDU1CUD4
I have found a matching bootloader here (not sure if this bootloader is needed I have not tried to flash magisk without it) - after flashing the bootloader and patching the official firmware AP with magisk and reinstalling it I get a rooted phone.
The last official rom i could find is dated 2021-04-23.
There are some suspicious sites that claim to have newer firmware that cannot be downloaded without subscribing/paying and then getting taken for a ride throughout links that lead to dead ends.
My first question is can someone who knows this exact model tell me which is the latest official firmware for it? (if available kindly share a link to it)
Edited
The reason I would like the most recent official firmware is to run linux on dex. Currently linux on dex 1.0.51 (which i believe is the last release before it was discontinued - please correct me if I am wrong on this) says it will not run without the latest updates.
Click to expand...
Click to collapse
It turned out linux on dex only runs on devices with Android 9. So a downgrade is needed instead of an upgrade
Which brings me to my second question: is there a way to know if the hardware in my S10+ model is identical to the hardware on some equivalent USA model? The CPU/GPU are the same but is the rest of the hardware the same? Should the answer be yes would it be possible to flash my device with a more recent official firmware from some USA carrier?
On gsmarena only the following model numbers are listed: SM-G975F/DS (Global); SM-G975U (USA); SM-G975W, on sammmobile SCV42 does not exist. Since the box mentioned model as being SM-G975 I am wondering if there is some naming confusion and a way to figure out which letters to add to SM-G975 to find recent matching firmware or if my model is simply not widespread enough to have received the same attention other models did.
Is there a risk of causing irreversible damage (permanent brick) by trying to upload firmware for another model (most likely candidate SM-G975U)?
My last question is about TWRP, After downloading and flashing the latest S10+ snapdragon image pointed at by the TWRP app my device could not boot. Is there TWRP image compatible with my device?
Many thanks for reading so far and any hints/help provided

Simply installing magisk does not work you have to flash a "cracked rom" before (one that matches your current firmware) installing magisk. I used this one Cracked Rom for the latest available SCV42 firmware (the site requires a registration before allowing downloads).

On the contrary this thread is meant to attract people who want to solve the same issues. I did not try installing an international ROM (too big a task to regain all configurations and apps) , however my uninformed non expert current belief is that trying another country's ROM is not going to wreck the device. Worse case would be it will not work and official ROM will have to be reinstalled (potentially with a nand reset). I settled for using magisk debloater to hide/uninstall apps I did not want (branding on startup remains).

For the whole rooting guide you will need to find one on this forum. (the one i used installed magisk)
Hi. I'm wondering if it's possible to downgrade the bootloader and everything to Oreo. The entire reason why I bought this Note 9 in 2022 is because GSMArena said it came 'Android Oreo (Upgradable to Android 10)'. Sadly, upon unboxing and turning it on for the first time, it's already on Android 10 OneUI 2.5. Is there any way to downgrade it at all? How risky is it only in terms of bricking the device?
- I don't care about tripping flash counter
- I am comfortable with Odin
- I don't care about losing data/knox/samsung pay/blah -- it's all dreck anyways
- I need my mass storage mode, sd card writable, etc. I refuse to use new crappy Androids
- I care not about security issues so please don't mention this or any of the above. Answers only please
Baseband is FUE5 and build is FUF5
Model is SM-N960F/DS
Thanks in adVanced!

Unfortunately, once the bootloader is upgraded, it will block the installation of any lower version stock ROMs, so a proper downgrade to 8.1 is impossible from what I know.
What can be done however is to install TWRP, and see if someone repackaged the Oreo ROM as a flashable zip, which you can flash like any other custom ROM. It might have some bugs since it will be running on the new bootloader, but it otherwise should work.
Aha. So you're saying there's a chance I can get just an Oreo flash working on the new bootloader without downgrading it. I'll give that a try at some point; this way I'd be able to go back to a newer Android in case of some catastrophe. Thanks!
