Looking for the Latest Custom ROM for S8+ - Samsung Galaxy S8+ Questions & Answers

Hello friends,
I am back to this site after almost 2 years.
A lot has changed, it appears.
Till now, I am using my S8+ on its stock ROM, with latest updates released by Samsung:
SM-G955FD
One UI version 1.0
Android 9.0
Baseband G955DXXU5DSH3
However, as the device is out of its warranty period, I want to flash a custom ROM. Been doing this before on my older devices, but need guidance now.
Would appreciate links to the appropriate how-to section.
Thanks in advance.

Was looking for the same thing.

[Q] Is SamMobile safe? (newbie quesion)

Hello
I was wondering if the Roms available on SamMobile were really safe and clean? Given they're not working FOR Samsung, where do they get those?
I'm wondering because I noticed there was a link that came with my phone originally that wasn't there when I restored a ROM I took from SamMobile.
Thank you!

I flashed many devices with odin and firmware downloaded from SamMobile.com and i never had any problems with it. The provided firmwares are not modified and seem to be 100% official versions.
No need to worry about sammobile as it is safe and clean.
It is all in one resource for Samsung stock roms. I used so many roms for different models from there and never faced any issues.
Can you please describe which link you got additional ??

Nothing important really but there was a link to my carrier's mobile site and SamMobile listed the ROM with the name of my carrier. So I thought it had been modified. But maybe it's just because it's the same version as the one my carrier offers but doesn't come FROM my carrier?

No it's not official, I read somewhere they were named Samsung Firmware before they had to change to Sam Firmware at Samsung's request (before they were named SamMobile). I can't find where I read this though.

You're probably right, but one thing you can be sure that sammobile is a safe site....
Alright thanks everyone!
Not official, but safe. They make their money by subscription services for "premium" download privileges. Maybe ads too, but I use adblock, so I wouldn't see them.
Yes me too. But I do wonder where they get all those ROM since Samsung doesn't give the out.

Sammobile updates Samsung Galaxy Note 3 N9005 LTE
Hello,
Next newbie here
Could somebody senior please help me? I am wondering about official updates from Samsung for ROMs downloaded from sammobile, are they possible?
I've just installed Kitkat 4.4.2 on my beloved Note 3 after few days of using Darkera's Note 7 ROM when I'm tapping on "Update" in "Software Update" menu I get "Processing failed" message. Overall phone's responsiveness isn't that great, that's why I wanted to see if update is available.
Will appreciate any answers

You can't do stock updates on rooted devices with custom ROMs and custom recovery.
You have to remove root, you also need to have an UNMODIFIED system partition and you need stock recovery.
If you're using a custom ROM(your note 7 ROM is a ported stock custom ROM) then that means you are rooted and probably have custom recovery which means you need to remove root and undo any system modifications that were done in the custom ROM(including any special themes and Xposed) then flash stock recovery instead of custom recovery.
Then you might be able to do the updates but the system will be looking for your device to have straight stock with no modification, if there is any modification left behind then the update won't work.

Hi!
Thank you for your message.
Here is the list of things I did to my poor note 3 :
- rooted
- installed Darkera's note 7 rom, custom recovery and kernel downloaded also from Darkera
- unrooted with supersu
- using Odin3 I installed kitkat 4.4.2 which I downloaded from sammobile (I was told this process gonna whipe away everything - custom rom, custom recovery and kernel)
- downloaded supersu to make sure root is gone
Because of sammobile's server maintenance happening this weekend I used kitkat file I downloaded from sammobile quite some time ago (N9005XXUEND3_N9005XEOEND2_XEO for Poland) and during flashing everything went ok. But now when I go to 'settings' and 'about device' imei, modem version, baseband version are unknown and when I try to hit 'update' I get "processing failed' message. Oh, and I'm also experiencing random reboots. I'm not sure if all this is a normal thing or perhaps I did something wrong.
I hope I didn't bore you to sleep

A few questions

Hey guys! So I have a few questions about the oneplus one here, I'm checking for a friend and I always had a nexus where matching firmware doesn't really matter much. So here they are.
1) What happens if you have the wrong firmware for a rom? Softbrick? Hardbrick? Nothing at all?
2) For a Nougat rom, what firmware do you use? Since this phone hasn't got an official firmware update for Nougat yet.
3) Is there a special recovery here on XDA that can flash all roms? (there was one for the oneplus two) or is TWRP good for all roms?
What confuses me the most about oneplus devices is how the firmware works different from most Android devices. Thanks guys!

Thanks! So it's not as important as it seems? I notice some roms here on XDA specifically say to have the newest firmware, or a certain version. The rom is still expected to boot? And what's the worst case scenario? A soft brick that can be easily fixed with TWRP or something worse? Thanks for the reply! Like I said, I'm coming from a Nexus 6 where none of this firmware stuff really applies :angel:

Yes the rom is a still expected to boot,though,the recommended frimware is to be used so as to avoid any bugs.
However,some roms do require the recommended frimware in order to boot but I don't think even if flash any rom which needs recommended frimware will take you in any kind of brick condition as when you flash a rom on incompatible frimware you'll see error in Twrp,if so happens you just need to have recommended frimware in your storage and flash it then flash the rom again and you'll not face any errors.
Good luck!

1. If you are using TWRP, nothing will happens. Because when you flash a ROM, TWRP will comparing your phone model with build.prop on the targeted ROM. Because based on my experience, somehow i download LineageOS for d802 and flash it to my bacon. TWRP gives an error and didn't flash any firmware. I don't know about CWM or other recovery
2. I'm using Lineage OS. It's pretty good so far. No bug or whatever
3. TWRP is good for all ROM. i think any recovery will do

How to get stock rom from samsung?

Hi.
My phone is SM-N910CQ
Current android version is 6.0.1
I want to install Android 5.1.1 stock rom from Samsung.
I did not try any roms, Kies, Sammobile.
I think, Kies will install latest Android version.
I don't want to use Sammobile. It is not official.
I have never rooted. (If I need, I can.)
I have an idea to get stock rom from Samsung.
I cannot try because I don't know how to do it.
My idea is:
1 - To change my phone firmware version with older than current version. (It will need roots.)
For example: Android shows current version is 4.4.4. Actually Android is 6.0.1
2 - If it can be success, when I check my phone to update.
I can get stock rom from Samsung.
But. Even if it can be success, Samsung can give me the latest version. (So, 6.0.1) (I really don't know the results.)
Can it work?
What do you think about my idea and how can I do it?
Thank you.

There is nothing to worry about from Sammobile, many people use Samsung firmware from Sammobile. I've used firmware from Sammobile many times.
If you're looking for an "official Samsung site" offered by Samsung themselves to download your firmware, you won't find it. Samsung has an "official" site with downloads for their devices, but, they do not offer firmware for every model number/device they make. I've already looked, they don't have firmware for SM N910CQ there, they only have a few different firmware for a handful of SM-N910 variants.
If you want to flash your device, you have no choice but to get your firmware from somewhere other than Samsung themselves, whether you like or not. The rest of the community of Samsung users has to accept this fact, you are not any better than the rest of us.

Thank you for your reply.
My phone version does not appear on Sammobile. Thank you for looking it for me.
It seems I have to continue to use my phone with current Android version.
Also I have to take a backup of my rom to prevent future problems.

Here is 5.0.1 for your model number, are you in Turkey? If not, this is firmware may or may not work for you.

Thank you so much. That URL has been broken.
Except one thing my phone is fine.
After about a minute of playing, FPS starts to drop.
There can be many reasons for this. However, I found a strange solution.
However, this solution is valid for about a minute.
I return to the recently used apps panel. And I'm back in the game. Without closing the game.
I can play with 60 FPS for about one more minute. This is such a cycle.
I could not understand the reason for this. It looks like a software bug.
Do you have any information on this subject?
Thank you.

HTC U12+ | No Major Android Updates on the Horizon | Options?

Hi all,
It's been a good couple of years since I've participated in these forums.
I've an U12+. Can't say I'm exactly happy with it however, and now even more so as HTC have confirmed Android 10 isn't on the horizon at this stage, and as for v11 forget about it. See below for the exact reply I received.
For your device, upon reviewing the android 10 is currently not yet available on your phone and in Australia. I’ve also confirmed that we still do not have the time frame when will the latest android version be rolled out.
I've been unable to root my device as I cannot find the stock ROM for it if I ever needed to roll-back to stock or for some other backout reason.
So with this said, what are my options for a major update to either Android 10 or even 11? I know there's the ASOP project but what else is out there in terms of updating options?
Really looking for suggestions/options in terms of an upgrade.
Thanks all in advance.
Anyone have the stock ROM for Taiwan version ?
HTC didn't release the stock ROM for Taiwan version, if I have it I'd try viper experience android 10

I have an Australian variant, and I don't think they released the stock ROM for this and I forgot to grab a copy back when I received the v9 OTA.
So you'd recommend Viper as an alternative ROM? Are there any other 3rd party ROMs other than Viper, ASOP / GSI ( I'm pretty sure GSI is at v11 ).
Viper can be found in the ROMs section of these forums?
Thanks for your advice.
According to mikalovtch there'll be an android 11 viper rom for the U12+, soon™. So waiting just a little longer might be worth it.

I just bought the device a couple of days ago, and bricked it trying to root it, and i was stuck for more than 12 hours in a bootloop, but i managed to get the original firmware at the Russian forums ( i don't know if I'm allowed to say it's name or post a link)
Anyways, if you want the stock firm ware for the device pm me your CID.

FWIW, I have a T-Mobile S22 Ultra that I fully flashed to the US Unlocked version (XAA) & the Samsung Members app still recognizes it as a T-Mobile device.
As I mentioned in another thread, I am on the One UI 5 Beta, so, I can guess that the T-Mobile &/or US Unlocked versions are currently open to the Beta & AT&T isn't (as of August 7,2022).
Did you end up manually flashing the Beta via ADB?
