Trying to root my Galaxy S8+ - Samsung Galaxy S8+ Questions & Answers

Recently I've tried to root my Galaxy S8+ SM-G955F.
I couldn't connect my device to my laptop. It just wouldn't recognize it. I've tried with 3 different cables maybe all of them are not data cables but I'm not sure of it.
Also, when installing Samsung driver on my laptop, it would install it but it never showed up in the device manager.
I was going with Magisk. Should I try to fix it and still use Magisk or other method?
I would like to know also if there's a way to root it without my laptop, if I end up not being able to fix the problem.
This might be dumb of me, but I've not updated my device since October last year. Because I tried it back then and couldn't root it, so I've stopped updating it to maybe be easily to root it. Was that not a good idea?

[Q] Samsung Galaxy Ace Rooting Problem

Hi, I have bought an Ace ME ROM version for my fiancée that had Eclair installed. I rooted the phone using superoneclick v1.9.1 and everything was working fine. Then my fiancée connected to Kies and tried to upgrade to Froyo however the phone hang and she removed the battery and then the phone was not working anymore. I got the phone to work again by reverting to factory settings from the recovery mode screen, and the phone was upgraded to Froyo. However, the phone lost its root, and I am not able to root it again, once trying SuperOneClick the phone hangs on waiting for device (even though I tried all remedies to this issue that are available online). I tried to install Z4root on the phone to root without connection to PC however the application crashes when I click root or unroot.
By the way, the phone says that it is rooted in the settings/About phone/Kernel version screen.
I would appreciate any help on how to re-root the phone as due to low capacity, app to SD and removing stock apps is necessary.
Thanks in advance for your help.

Issue since cm11,4.4.4, es manager and usb not recognized

My 959V is rooted, had plenty of roms,ect over the last 3 years decided to do Gremlin remover and update it...,
Couple days ago upgraded to the "909" download of CM11,4.4.4, but every site I get it from gives me 908 (even though they all say 909) (last 3 digits of download version). The 908 will not recognize on my Win 7 laptop, but was fine up to now with previous cm11 same phone..
I have used the same cable for the last year for both my Galaxy and 2 Sidekicks phones, data and charging, now the Galaxy only charges, Windows detects but wont recognize, does on the sk4g's
Also (908) will not allow me to paste into sys/media with a " read only issue", although up to now swapped 15 different bootani without problems. Tried 3 different root file managers,same outcome.
Is the driver for the phone firmware windows looks for(on the phone itself) replaceable from sdcard? Im guessing its a bootloader issue and the 908 is the one not to of put on my phone.
Whats the probability I am getting the 909 but the 908 will not allow it to surpass it. Goes through the whole flash and on reboot I have to reenter emails,playstore apps,ect, but on 908 still in settings.
I can/ have been able to swap 1 rom via twrp and sdcard on 908 ( to slimkat4.4.4 and back to 909, but comes up 908) any other roms error before flash(and slimkat does not recognize on usb either).
is it a Kernel fix, and can it be flashed via sdcard? Bootloader via sdcard? Bad usb port? Does charge, and the drivers/ cable verified.
Thank you for any help, been 3 days now, redone my laptops (2) from scratch, everything ,c++,java,netframework,samsung,zadig 2.0, and more.
DId you do a clean upgrade (did a factory reset) before you installed CM11? If you didn't, go into TWRP and do a full backup (/system, /data) and do a factory reset, then boot up the phone and see if your computer will recognize it.

Yes, cashe,factory and davlik, before and after flash. I also have a 2nd motherboard,swapped them out and seen that it also is the 908 download but does recognize and allows me to ES Explorer swap boot animation. Im guessing I somehow erased the driver from the phone itself.
Ive done some Iphone jailbreaking unlocking for friends and found that a certain baseband (if I remember right 5.13.xx or 5.16.xx) would basically lock the phone unable to downgrade or upgrade and was to be avoided. Wondered if this a similar issue. (screwing up my bootloader)
What does windows look for via usb in the phone, adb,? Is it in the kernel and reflashable via sd?
I read also that the mini usb port can get bent over time and needs centering, tried that, cord fits better but not the issue.
Tried to zagdig the 2nd motherboard (worked) for drivers, but the 1st one still has error,device malfunctioned and cant be recognized by windows (7).
If i can get the Anton basic with a twist (no rom just the cm,I have it for Oden but wonder if Its possible cm flash)., Im good I believe,thats how I first rooted and got 4.3 cm,then 4.4.4, 908. Dunno,willing to try anything, not worried about it as I have a 2nd motherboard.
The rom is awesome, with no isuues except the battery stats vary. It says 3 hrs left then dies 10 min later, tried to erase the battery cashe in recovery but doesnt change anything. (related via usb?)
Thank you.

I didnt do a backup, if thats an issue , can I backup 2nd motherboard and apply to the first?

You can flash new kernels via recovery but it sounds like your issues are bigger than that. The fact that the 2nd motherboard is recognized via USB but not the 1st suggests that there's some kind of hardware issue. The drivers on your computer are working fine since the 2nd mobo is recognized, and so is your USB cable.
Why not just keep using your 2nd mobo? Is there something wrong with the 1st?

O.K., so Ive been playing with the second mobo just to test different angles.
1) E.S. File manager is the culprit, swapped out for a paid app Ive used with Sidekick 4g, Root Explorer, and boot ani. goes fine, on both mobos.
2) The latest gapps (cm 11 w/ gaps 4.4.x) was giving me a "Google servers cannot be reached" error on both mobos, used the gapps for cm 10.1 (jb 4.3) and all is working, both mobos.
3) Was reading that possibly the adb driver is in the kernel, and thats what windows is looking for? Ive tried but can only sd card flash at this point so, giving up. I can bluetooth,wifi share or email files to myself if need be. Im guessing its a hardware issue beings that the 2nd mobo was reflashed identical to to the first. (with exception of one click 2.3.6,and w/a twist oc/uv on the 2nd),1st one will not downgrade at all below 4.4.4 by sd, I was trying to ics a rom guessing the foundation might overwrite any missing stuff then upgrade back to 4.4.4.
One post mentioned that the mtd/bml cross flash is a no-no, could that mess up usb driver identity on the phones side?
Not a big deal, both phones/ roms are working great and have no issues (except 1 doesnt connect to a computer for file transfer). Thank you for your help.
Little early to ask but are you going to be in this forum long enough for lollipop to be ported? I would send you this phone for devving if you think you can get it to transfer files. Also need to get a lcd/digitizer, i have the rest of the phone.
Also, the phone was working fine up to about a month ago, it was recognized by the computer, only difference I made was trying apps, off playstore, five fingers for ebay,different weather apps for widgets,silver/gold prices apps. Thats when it started not recognizing.
I was getting the same error about the google servers, then I tried a earlier version of gapps. Connects now.

I have no plans to try a Lollipop port, this phone is almost 4 years old now. You might be better off sending the phone to @bhundven since I recently got two dev phones donated to me.
As far as the phone itself goes, the phone should be recognized even if there is no driver for it installed on your computer. You can use this software to verify that
http://www.nirsoft.net/utils/usb_devices_view.html
I don't believe you can even edit anything on the phone to make the USB device not be recognized when plugged in short of bricking your phone, so if there isn't even a USB connection being made, as I mentioned before, it looks like a hardware issue is causing your problems.
In that case, it'll be hard to flash anything without going through a lot of hassle since all the reliable recovery methods we have need that you are able to use your USB port on the phone.
EDIT
If you do still have TWRP available on the phone, flashing any ROM will reflash a kernel, but be careful because the recovery is tied to the kernel and some ROMs have a non-working recovery, so if you happen to flash some of these you'll be stuck with a nice paperweight . The latest CM11 I have posted does have a working kernel/recovery but I still don't think it'll fix your issue.

I'm currently looking into it, as well as fixing some issues with cm11. I have an SGS4G, so no need to send a phone.
Not just is it a 4 year old phone, but I am not sure how many people even use this as a daily driver anymore.

I still use two of them. Great little phones really. I see no need or use for 5.0 I think running this CM11 from you guys is about the end of the road for these phones. A great ride indeed. Ill be sticking around regardless just to see what happens. Thanks guys☺

My S6 Edge ROM possibly corrupted

Okay, here is my problem. I was on a custom ROM and decided to put the stock ROM back on to give it to my son. I did and everything was working fine. It then did an upgrade weeks later to Marshmallow and fast charge stopped working and when I connect it to a computer the computer does not recognize it. Gives an error message saying can't recognize the device. Yes I have tried the following:
1. Made sure fast charge was enabled.
2. Tried several cables and fast chargers. (I know they work because they work on my S7 edge)
3. Took it to Sprint and they said it was the USB port. Had it changed even though I know that the software caused it. Still did not fix the problem.
4. Made sure USB was set to 'charge' using USB debugging.
5. Completely factory rest the phone... Several times.
6. Tried several computers and installed and reinstated the Samsung USB drivers.
Anyway, is there any way I can root the phone, put a custom ROM on it or even re apply the stock ROM on the phone without having to Odin?
I don't have the advantage plan so they want to charge me $700 to replace the phone. I am positive it was the software update that corrupted something. Any help would be greatly appreciated.

Is there anyway to root and flash a rom without using the USB port? Any advice would be greatly appreciated. Thanks

HELP theres somthing wring with my phone

i have a samsung galaxy note 4 (SM-N910C) running android 6.0.1 and its been with me for almost 3 years. but recently i rooted it multiple times using odin and chainfire cf autoroot the first time i rooted my phone succesfully then i figured that i wasnt able to use snapchat so i completely unrooted. then i realised that xposed was what caused snapchat to stop working not the actual rooting. so i rooted my device using the same method and it worked succesfully. but this time i THINK i messed around with the build prop file but at that time i didnt know. so a couple of days later i completely reset my phone( just because i got a new work phone but NOT because i thought somthing was wrong with the build prop file) so my device wasnt rooted.then when i installed snapchat again and it didnt work.then i went to see if there were any software updates and it said the i had an unothorised OS.then i went to my device status and it said costom instead of original which was weird because i reset it. so i starting think abought what could have gone wrong and i thought about the build prop. i tried everything to get the device status to original like triangle away (i had to root it to install triangle away tho) but it didnt change the device status but snapchat worked thank god. however private mode didnt work so i tried to install samsung USB drivers and connect it to my phone usibg odin but things got even more copmlicated. i dont know what to do
any ideas?
flash stock rom via odin ?

Note 20 ultra N9860 Twrp help

So ive been rooted since this phone came out like 2 years ago, but without recovery. Its my first android without twrp lol and it sucks bc if i ever bootloop i just have to factory reset. Thats the reason why i haven't been using xposed. When i try to install twrp in the rom flashing process its frustrating bc you cant get into recovery without a usb connected or some dumb issue. And its hard after the phone restarts, i cant get into recovery. Is there another way to install Twrp on N9860? Like this is the only phone like this, where you need a usb connected to enter recovery, they messed it up on a bootloader update i think. Anyway helping me is much appreciated. Also if i can get twrp on my phone, whats the best way to installing edxposed, or lsposed. Taichi is kind of a hassle
