Help

I need some expert help with my samsung galaxy s8 Plus. I want to reset it to factory settings. The option to restore to factory settings is greyed out. Also, when I go into recover, (volume up, bixby button pressed down then power), i can select wipe/factory reset but when I try this option, my phone just restarts. Its on OFW and android 9, baseband is G955FXXU4DSE4, latest update installed. Any help with this would be very much appreciated. Thanks in advance guys

Hi guys, i need someone to help me, i just got the s8 and trying to upgrade it to pie custom rom. But i notice that my s8 is a bit strange, I can't find the OEM unlock in Dev. Option. But it seem that the rom is already change ( not officiall ) and the knox has been triggered, when i check via knox checker..now what i want to ask is, can i just use odin to flash the pie rom

P.S i think my s8 is a single sim version that was changed to dual sim, considering that the imei is the same both sim1 and sim 2, but it works though.

Any help would be great. Im not noob on rooting and adb, just noob with samsung devices

[Samsung Galaxy S8+ Questions & Answers] Dashound876:
I have a FRP custom binary locked S8+ that when booted greets me with the "an error has occured while updating the device software.Use emergency recovery function in the smart switch PC software". This does not succeed .It was magisk rooted, however it was reset and is now FRP locked. I can still boot into download mode however, I am unaware of which firmware exactly to use. I am unsure of region or version and have been trying in odin with multiple versions however they all fail. My CARRIER_ID is TEL if that helps and I can provide any other information people need.

Looking for any help/advice.

Hats off to everyone on this forum. It's been awhile since I been on here and I am happy to see it still going strong.

I am new to the S8+ and new to modding in 2019. I haven't messed around with this stuff since the "getting the evo to work on boost" days. I am looking for some advise/recommendations on what to choose as far as roms, etc., from the gate from someone who may have had an experience in what I'm trying to achieve rather than going through hundreds of rom post to find the answer I'm looking for.

I am looking to root (if needed anymore) my device and install an ultra slim/lite rom, no extra apps on it that don't need to be there, especially social media apps. Not sure if roms still come with a separate gaps install option but not having them is fine as well as I will not be signing into any account on my phone and will only want to use youtube as far as the only goog service used, so i wont be able to use any of them anyway besides tube (unless of course there is now a way to use maps and such without signing in?). If theres such a rom out there of course it would need to be stable. I do not want android 9 as none of the apps I actually use (like bk disabler/acr/etc) work with pie from what I have read. Goog wants all the tracking to themselves now I guess, hence why I am looking for a rom that is as slim as possible. I just want to make calls, text, browse the web and use the tube without having all kinds of accounts and sign ups for any of it. I am getting really tired of big tech but going back to a black and white nokia in 2019 is not an option anymore.

So a few questions I have would be.. Whats the best root process? I see Odin is still a thing so which version should I be using, also which kernel should I be using? Are different roms still based off different kernels, if so which is better? And lastly what rom should I choose or which rom creator is now the person to look out for?

I know I'm oldshool at this point so please bare with me on these questions. Any help in pointing me in the right direction would be very much appreciated. Thanks!

Hi all, it seems like I'm facing a similar problem as many people in the last 10 or so pages. I have never installed any custom firmware and have never tried to root (since the AT&T bootloader is locked), but the latest OTA update made my phone get stuck in a boot loop with only access to Download mode.

My S8+ is a pure stock SM-G955U (AT&T) and I was notified of a new system software update yesterday, which I proceeded to install and upon device reboot, gave me the message "System software not authorized by AT&T has been found on your phone. Please turn off your phone and go to the nearest AT&T store for help." It also says "SECURE CHECK FAIL : boot" in red text on the corner.

I was post-Android Pie update with the Samsung One UI update, so either the May software update (G955USQU5DSD3) or June software update (G955USQS5DSE5) and I have tried to installed these via Odin v3.13.1 as well as the intended update for the July 31 release (G955USQS6DSG4) with no luck. I used Frija to download these firmware versions from both SPR and TMB, which I have read to have worked for others.

I've tried visiting several AT&T stores and calling AT&T tech support, but of course they don't know much about troubleshooting this weird issue and blaming it on a failed root attempt. I was told to take it to a UBREAKIFIX store (certified Samsung Care) and even they failed to reflash the phone. The techs ultimately told me to send the phone to Samsung for repair/replacement or get a new phone. I can't be out of a phone for an extended period of time, so I went out to buy a Galaxy S10+. However, I would still like to try to resurrect my S8+ if possible and just return the S10+ as the holepunch design is jarring.

Thanks in advance for any help that comes my way!

Hi, guys i am looking to root my Samsung S8+ Currently the Samsung Exynos

G955FXXU5DSFB

i have followed a video guide but i am stuck on which TWRP i download, "America or Europe"

as my phone is Australia based.

It has been awhile since i been on android and just got an S8+ today, so im currently lost on all of this.

does flashing roms do anything to my carrier? As i am looking to flash https://xdaforums.com/galaxy-s8/sam...ovate-ice-g950-g955-android-7-0-aqdg-t3598040

and im looking to flash NX Kernel as well. Just want to know if it would mess up carrier singlas at all. As i have done something along the line before and it runined my carrier signal and my phone ended up bricking.

Just tried to downgrade my s8+ from Android 9 to Android 8 but seems to be getting fail everytime i try. Not sure why
[Samsung Galaxy S8+ Questions & Answers] spawnlives:
Not going to be much help with customs rom as I'm using stock rom. I would suggest having a read and see what issues other people were having.

If you do give it a try and something goes wrong or not as planed you should be able to flash stock rom to get out of trouble.

Also the problem with Samsung roms ( as well as custom ROMs ) is you can not downgrade to a previous version due to bootloader version numbers. Bootloader version number is the 5th number from the right of the firmware file name when downloading firmware or you check in about phone and check baseband info.

Ah okay, so i guess that solved my problem on why i cannot go to 8.0 lol, so ill stick with stock rom and maybe when i get the note 10 ill try to flash different roms. Thanks for replying to me and answering my questions. <3

Hi,

I need the correct version of Odin and firmware to use to update my samsung galaxy s8 G950FD. I'm in Nigeria.

Thanks
[Samsung Galaxy S8+ Questions & Answers] spawnlives:
Use Odin version 3.13.1 or later.

You can use websites like sammobil or updato to get official firmware. You will have to search for your model number,region and maybe carrier version. If your don't know your version revision is download the latest firmware.

Or use PC apps like samfirm or frija to download latest firmware available.

It gives off an alarm followed by this on screen message.

(there is not water in the port)

If I switch off the phone it will charge normally but that's super inconvenient!!

Ugh, I can't upload the screenshot. Keeps saying network error yet I've got full service... ?

Seems there is only one promising rom, (https://xdaforums.com/galaxy-s8+/development/rom-pascal-rom-s8-t3671505), but is with android 7.0

My advice would be to get root and twrp recovery. Then make a full backup of everything. Start by uninstalling every app and check if your device keeps its functionality. Trial and error. Also, for performance, try overclocking and using FDE. AI. Good luck

Can anyone here help me with my Galaxy S8+ (G955FD). It froze during a game and I had to restart the whole phone, then while it was booting it automatically went to the recovery page without me pressing any buttons. Pressed Power Down button to reboot the device but after the Samsung logo it just went to back to the recovery page. It says something like firmware not valid.

Tried flashing the device exactly I saw on some videos on Youtube, used latest firmware from Updato, Samobile, Odin says it Passed but it still wont open and keeps on going to recovery mode.

Please help

Got an S8+ from Korea through eBay. It cannot make VoLTE calls. Can I fix this?

Hello, XDA community. I literally just made my account, so please forgive me of any faux pas I may commit.

I recently bought a Samsung Galaxy S8+ specifically to use with its keyboard attachment, and I cannot seem to make/receive calls on it. I have tried looking through the settings and see that there is a GiGA LTE thing that is disabled as long as I don't have a KT SIM card in the phone.

So, I think that this may require some sort of ROM (which is fine as I was going to install one anyway, but it will have to be compatible with the keyboard attachment), but I know that it's not always the case that a ROM will fix this. How can I determine whether or not this is something that a ROM can fix?

If it can't, then it likely isn't a big deal, as there are second-hand vendors in my city who sell the device for the same price, and these may likely be US ones.

For the record, its model number is: SM-G995N

Thank you, and I'm looking forward to one day being a larger part of this community!

is this alive ??

Hi XDA!

So this is the stuff, I dont know what to think right now, but the following happened:

Im checking notifications and messages every 10 minutes or so as I'm using my laptop to do some work, and all of a sudden I'm going to check my phone, and screen doesnt turn on!, phone seems to be still working, able to use volume buttons, bixby remapped button (1 time screenshot, 2 to turn on/off flashlight, hold for G Assistant), so I'm like "okay, screen seems frozen, never happened before, let me restart" so Power + Vol Down, wait for feedback, hear the phone restart but SCREEN STILL OFF, been trying to restart couple times, still nothing, now I don't know what to do.

Phone haven't been dropped or anything, pretty sure still above 50% battery and everything,

but as I already restarted, unable to unlock it using fingerprint so I'm out of ideas.

Any advice ?

Do you have automatic updates active? Perhaps the phone updated itself and something went wrong, some app was missing or something similar. See if you can boot in recovery.

Hi XDA :),

Total noob here, so please forgive me I'm advance. I just bought a Samsung Galaxy S8 and I'd like to learn a little, from hands on experience messing with it. I actually have two, but the one I want to mess with is the one I'm using now. I do not have a PC, so I know I'm quite limited on what I can do, and the difficulty it will impose on everything I attempt as I go.

I'd like to learn how to do everything start to finish involved with using a custom ROM. I know there is quite a bit, and I have a lot to learn as I am very 'noob'. I also know I risk my phone, and it may become completely unusable or I may even compromise my phone's security. That all being said, I am and would be greatful beyond words if I could get some advice, information, and or some links that are specifically for my phone and situation(as much as they can be). If anyone is generous enough to spend their valued time in helping me achieve this my thanks would go out to them, and then some.

Thank you in advance to any and all who reply,

[Samsung Galaxy S8+ Questions & Answers] Raresh T:
Mate, without a computer, doubt you can even try using a custom rom. Just buy a computer, you don't need the best. Any 100$ computer will do.

A computer is quite important. You need Odin in order to unlock your bootloader, recovery and custom rom. And Odin only works on a computer. No computer, no Odin. No Odin, no learning stuff for you.

I won't manage to root my 8+ with CFroot, need help

Hi, I am trying to root my 8+ SM G955F because Samsung wil give no update to Android 10 for this premium device I bought 3 Years ago for 850 euro! Not very client frendly. So I have to root it to flash a custom recovery on it and after that I will look for a Android 10 rom without any bugs to use the 8+ a period longer. I have not much experience with rooting , but with CF root it should be quitte easy. I did all according the advices , even removed my account, but during flashing there is a failure when the img is written. I can't find out why.
