So here's the thing. An exploit dated back at around 2006 was discovered recently that potentially gave the user access to write on read-only files in the system. Google has only patched it recently in the latest November 2016 security update. Since Samsung couldn't bother to update us past the August 2015 update, there's a strong possibility for temp-root here.
Here are some links for further investigation:

2. http://forum.xda-developers.com/general/security/dirty-cow-t3484879
3. https://github.com/timwr/CVE-2016-5195
I'll see what I can do, but anyone who bothers to read this, please share this to developers and ask for their help. Thanks for reading.

This file is ADB sideload only. I hope you know what you are doing before you trying to flash this. Don't ask me how to do it there is plenty information on XDA forum to learn how to flash this by ADB.

Appreciate the help.
If possible , whenever a new update comes on , can you update the OP with latest patch ?
Or can you let me know how to capture this update ?
Thanks for your help.

Anyone have G930AUCU4BQG1-to-S4BQH1 file i need for update software cause your link was deleted
Heya. I read and seen on several sites that the A10e was going to get the One UI 2 update in May of 2020. It's June and I still haven't even gotten the security patch due for May, let alone a Android 10 update. This is on the Metro by T-Mobile variant SM-A102U
Update: I found that the A102USQU6BTE4 baseband of the A102U has gotten the android 10 update, but the ATE5 versions got a security patch instead. Will the ATE5 versions get the update eventually, or can I take the BTE4 version and flash it to the phone through Odin? (I'm assuming that'd obviously be a know). Hopefully I'm posting this in the right place.
I have an app that does not work after Android 8 that I need and there is no replacement in 9 or above. I managed to avoid updating my v30 to v9 and later for a year or so. It accidentally allowed the update to 9 this past weekend while I was camping. All I want to do is roll back to stock v8 or 8.1 (Oreo).
I have enough tech knowledge to follow directions and understand rooting but am having a really hard time finding the "right directions." As I was reading some of them, I found caveats like, "Use X unless you have the delta update and then use Y but not if you want to run Z. For Z, you have to follow this other thread." I also know that using the wrong settings or data file could brick the phone.
So, I'm hoping someone can help me narrow down what sets of directions I need to follow.
Here's what I have right now:
LG V30 (VS996) On Verizon Network
Developer Options Enabled
Android V9
Security Patch Level August 1, 2019
Kernel Version: 4.4.153
Build #: PKQ1.190414.001
Software version: VS99630c
Again, all I want to do is roll back to stock v8 or 8.1 (Oreo).
Bonus would also be a way to stop asking me every day to update or delay a day and just wait until I manually do it.
Thx in advance!!
Download the right firmware file for your device from here -
Models - LG-Firmwares.com
Free archive of LG firmwares. Comparison of features and reviews of all mobile devices. Quick download of updates for your device.

Then download the flash tool from here -

LGUP tool is the latest version of LG Flash Tool that allows users to flash stock firmware on LG smartphones and tablet devices. Download LG UP tool 2018 from the official download links.

Follow the instructions on both the pages. I think you can take it from here.
Note that implied with this process is that you cannot downgrade your firmware without wiping the phone... there's no way to "patch" back to the old version. So, be sure to take backups FIRST.
If you're rooted on the old firmware, you can then disable/freeze/delete the update APKs so that the update warning goes away. But this requires root, so be aware of that. If you don't haven't rooted already, then this is a process of its own, and will require you to go back to Nougat in order to perform that, so you may want to do that before installing the final version of the ROM you want. You can find out how to do this rooting process on the WTF thread, post #193, located here: https://forum.xda-developers.com/t/...ar-instructions.3790500/page-10#post-76584629
If you don't want to root, that's fine, but then you must endure the update warning process... unless you can find another way to disable the update APKs.
Thank you both. I expected to wipe the phone so that's not an issue. I will first install Nougat, root and then update to Oreo.
There are about 14 Oreo ROMs on that site. Do I just pick the latest one or do I have to pick the earliest one and update that?
Pick the latest one.

Hello,
I recently acquired a refurbished S9+ and as many other people, I realise now that someone must have been messing around with the internal software. This is my secondary phone so it's no big deal but I would like to understand what was done on it nevertheless, and maybe turning it back to a cleaner state, if possible, and if it has not too many drawbacks.
-apparently, Samsung Pay is not working. It hangs indefinitely on the screen where you must choose the type of security.
-when looking into the Play Store settings, the device is not certified
-WiFi calls apparently are unavailable
-OTA update is not working (nothing happens when I try to check for an update manually. What's more, no information about the last update is available. By the way, the phone software is outdated. (last Android security fix is dated from Feb 2019)
From what I read, it looks like the CSC was modified, right ? Would it be a good idea to change it back to original ? (I may need some guidance about that but we are not there yet) Would such a procedure restore, for instance, the OTA update feature ?
(see pictures attached - there is what is written on the phone's back cover too, if it can help)
Thank you very much in advance. Please tell me if you need some other specific screenshots.
PS : I also bought a Note 10+ from the same refurbisher and it ended up being a Korean model. But the firmware seems clean. I know Samsung Pay won't work in France, WiFi calls either, and I will be stuck in "LTE" 4G instead of 4G+ but at least OTA updating is functionnal (I got an update a few days ago) and honestly ? That's fine with me for the price.
Anyone ?
From what I've read researching on similar issues, the previous owner who messed around with the internal software must've flashed custom firmware on your S9+, and probably tripped Knox (and is why your Samsung Pay app won't work). According to some developers on here, you're able to hide the fact that you've rooted the phone, but I don't think you can un-trip Knox once it's been done.
Prior to your post, I didn't know a single thing about CSC and I'm not sure how it's really relevant when flashing a mobile device (unless it's carrier-related), but I think all that's required when flashing a device is the model number. Luckily, I stumbled upon a thread that is actually your exact, same model! Do what you please with it, and I hope I helped — I'm not a professional, nor am I really knowledgeable about all of this stuff, but I'm trying.
This is the thread I was talking about:
Official Stock Firmware Thread (11 August 2022) - Galaxy S9+ (SM-G965F)
UPDATE (7 APRIL 2022): Samsung has officially declared the Galaxy S9 and S9+ EOL. They will no longer be supported, and FVB4 will most probably be the final build for this device. Latest stable firmware: G965FXXUHFVG4 / G965FOXMHFVB4 /...

You're welcome! Was it what you were searching for?
Not sure, but I hope it will help me understand the firmware/CSC stuff better
Alright so apparently this phone actually is a SM-965N, judging by what is displayed when booting into download mode.
Unfortunately I only saw this after starting a flashing attempt with Odin and now it's stuck at "system.img" so... I'm gonna let it run a few more hours but...
It's most likely bricked at this point, isn't it ? (edit : interestingly, after I forced-closed Odin and reboot the phone, it was not)
If you ask me I find this kind of "refurbishing" a little bit sketchy to say the least.
As In title.....Just installed it, but cant see anything different.....does anyone know whats new?
Matt
I am very sure that it is a security update that is targeted to make Android less vulnerable to hackers etc.
