S8 Plus not recognized in Odin or by computer - Samsung Galaxy S8 Questions and Answers

Hi guys,
I have a S8 plus with root and I tried to download the latest firmware in order to flash it but when I put the phone in download mode, it is no longer recognized by the computer or Odin. I have downloaded the drivers again, used a different port but with no use. I have 2 S8 plus, one without root witch works and connects with computer and this one with problems.
I tried flashing a custom ROM but again with no luck. The phone works just fine but Android auto is also not working just once in a while (strange) and I use it quite a lot.
Any ideas?
Device: G955F
Thanks in advance!

[i9000m] Bell Vibrant Fail to Upgrade via Kies, Advice Needed!

Hi guys,
I have a recently purchased Bell Galaxy S Vibrant, running 2.2 JL2.
I installed Kies, updated it to the latest version, plug in my phone and a message says new firmware upgrade available.
So I proceed and everything goes fine until the download mode. I see a little yellow Android construction icon on my phone (looks like in download mode), but on my PC, it always says:
"Failed to Convert to Upgrade Mode".
I have searched the internet for a week and tried everything and anything I found...but still no luck.
Any suggestions? Thanks.
Hi . I bet that the update is KC1 . You can find it here on xda and install it with odin if you can acces download mode ( VOL DOWN + HOME + POWER ).
Hi Omerx,
Thanks for the reply. Yes, it is KC1.
Regarding Odin...I've seen a few people mention it. Are there any downsides to using it? Would it be complicated to upgrade to gingerbread when it finally comes out if I use odin right now?
Also, I have to download the KC1 manually to use odin right?
Thanks.
no downsides: it is actually more transparent than kies on that you as suer set the parameters and identify the files you want to load
check around there are a couple of good threads posted on using odin and the basics of how to root and flash your own phone
kc1 is a good modem and a worthwhile update
hi guys,
I found some tutorial here on odin, but can't seem to find kc1 manual download for a bell vibrant, any suggestions?
Also, when I do it with odin, will it wipe everything I have on the phone (apps, settings, etc)?
Thanks.
nvm i got it to work in KIES finally!
Turns out it just doesn't work on Windows 7. I did the same process on an old XP machine and upgraded flawlessly.
Cheers.
the upgrade to KC1 worked fine on windows 7 64 bit here

[Q] Updating S5 to Android L Without Computer

i wanted to know if i would be able to update my friends GM900F to the newly released Android 5.0 ROM without a computer.
Only reason im doing this is because for some strange reason his phone isnt being recognised but my S5 (GM900H) is. When pluged in it doesnt even say connected as media device on the phone itself. Tried doing all i could, reinstalling drivers and what not even using another laptop on windows 7, and yes USB Debugging is on
he really wants to flash the new ROM badly and doesnt want to wait for an OTA,
I was wondering if in theory i could get it to work by rooting his phone with towelroot, installing Mobile Odin and then flashing the Firmware?
if it fails and is soft bricked i dont know how to go about fixing it cause it just wont recognise the device at all or install drivers, but my S5 (GM900H) gets recognised fine.
Has anyone ever used Mobile Odin to flash a whole new firmware?
any tips
Wait for first custom Roms and flash via recovery. [emoji52]

Odin doesn't recognize my s7 edge (trying CF auto root)

Hi, I've been reading the thread for CF auto root to give it a go. I've downloaded the drivers (I've got 1.5.51 now installed, haven't been able to find later ones), I've got the 2.74 SU version that helps to overcome a recent security policy update issue reverting root status and the CF auto root zip file (CF-Auto-Root-hero2lte-hero2ltexx-smg935f.zip) which has odin 3.10.6 included (not quite sure if I can use any recent odin version). I even got my stock firmware com sammobile and extract the proper boot.img from the AP* file (just in case I got something wrong at sometime). I've enabled the OEM unlock too on developer options. I understand I can give it a go without having to go with a custom recovery (still not sure and haven't got the whole picture about the dm-verity thingy and what effects has on the device but someone mentioned something like loosing the encryption or so). This is my first try on getting root on my s7 edge G935F (international version), so it shouldn't have any boot.img problem (but trying to be prepare since I can't go about without my phone being working).
So, I've got my phone into download mode, started odin, loaded on AP the tar.md5 file from the CD auto root zip file (CF-Auto-Root-hero2lte-hero2ltexx-smg935f.tar.md5), connect the device throuhg usb cable and I was expecting Odin to recognize it but nothing happens. Since in the threads I've been researching for s7 edge there is no indication on waiting to see something happening on ODIN (but in some other threads - not s7 edge related though - mention something about having to see a blue indicator on COM), I'm not quite sure if I'm expected to just hit start even if no apparent change is happening on ODIN nor there is some drivers installing/configuring when connecting the device on download mode. Since I'm quite new to this, I'm no sure if I should connect the device first with some other option enabled, like USB debugging or if I'm missing something quite obvious for someone familiar with flashing with odin?
Kind regards for any help!
PS. I did tried to find an answer through searching but foung nothing related s7 edge wise so I'm at a loss not even knowing if just hitting start without having the device recognized on ODIN will do any harm at all (that newbie I am)
Try odin 3.11
Aldo plug your phone in first and than once recognised load the autoroot to ap

Thank you skinza for your reply, I did tried what you suggested and although it wasn't enough for getting it solved it helped me to know I was on the correct path and that I could use an updated odin.. finally, the problem was on embarrassing one since I went into download mode but hadn't push the volume up to get into the actual ODIN mode (too newbie of me but I was trying to follow the instructions I'd found and none were that specific - a bit afraid of messing it up). Nonetheless, thanks again for your time! Kind regards!
Edit: Now I'm rooted (thanks CF) and it took less than expected (a couple of mins or so). I didn't go the custom recovery way, so it might have been that.

Thanks again! for now I won't be going for a custom rom but wanted to be able to install a firewall to stop some apps from draining my prepaid data (limited)..
I was planning on having xposed installed but it seems I need a custom recovery for that as well.. I used to have xprivacy on a previous nexus 4 and loved I could limit some permissions that are still missing now on marshmallow but haven't got a grip yet as per the effects due to the dm-verity thing.. would you happen to know anything about it? and I was also wondering about if I do need to have the OEM unlock still enabled now that I'm rooted? (The later because I'd been robbed of my cellphones in the past - even recently a new s7 edge that didn't last me even a month and wouldn't want to let them have an easy pie on having the device available)
Regards!
I'm facing the same issue but even after going into download mode properly after pressing vol up
odin doesn't detect my s7 edge
I've installed all the drivers also

Got the same issue. I'm new with this. My colleague wants me to learn and test and load Lineageos on some brand new S7 G930F devices he gave me which I have already switched to dev mode with OEM unlock and USB debugging on and the devices smoothly jumped into ODIN downloading.... mode
I also have the proper Samsung USB Driver installed. (did it several times after ODIN didn't recognize my device)
However, according to the manual, I should start up ODIN, then connect the device via USB cable to the workstation (as unsuccessful I already tried 3 workstations with Windows 7 and Windows 10) whilst having the phone in download mode... .BUT NOTHING APPEARS in the Log field and the ID:COM Box doesn't change colour and my manual says that it should.
My workstation however recognizes the devices with positive messages so I guess the drivers are good.
My co-worker gave me ODIN v3.10, but as this didn't work I downloaded and installed V3.12, but unfortunately also without any luck.
What am I doing wrong?
which OS?
S7 edge SM-G935F
Hey guys,
i tried rooting my s7 edge but after i got into TWRP my phone went into a bootloop. when i got back download mode, odin still found my phone, though everytime i tried to enter TWRP again, odin said there was a FAIL and my phone immediatly went back into bootloop. I tried to reinstall the samsung usb drivers but now odin cant find my phone anymore.
Before i screw up even more, can someone please help me? right now im stuck in download mode and odin 12, 11, and 10 all wont recognize my phone, also not if i use different cables. my windows laptop however still gives me the device found and device disconnected sound everytime i (dis)connect my phone.
any ideas?
thanks
EDIT: Okay i tried my USB 3.0 port and now odin found my phone. just weird... now i just need to solve the problem that I'm still stuck in the Bootloop but that probably doesnt belong in this thread

S7 Edge - Bricked

Hi Guys,
I'm a bit stuck and having tried to read as many posts as I can I still can't find an answer. I tried to put a custom rom on my s7 edge after successfully rooting it. Putting the rom on didn't go well and i'm getting the Kernel SeaAndroid error on startup.
I can still get to download mode/TWRP recovery but I don't have an SD card and I am using a Mac. Every fix I have seen seems to use normal ODIN for windows which I can't use. I tried flashing the rom using Jodin3.
At this moment, I just want to get my phone working so am happy to go back to stock initially. Can anyone help??
Thanks
Have you tried emergency firmware recovery or whatever it is via SmartSwitch? The Desktop application I mean?
Here's a link to the Mac version:

Really Tricky Problem

Hello people!
I've been doing installation of custom ROM and any kind of configuration for a while now. But I have now in my hands a tough problem. My dad bought athene XT1640-DS (Moto G4 Plus), just like the one of mine own, but mine doesn't have the '-DS'.
But the device is stuck at Stock Android 6.0.1 and I can't update it.
The USB seems have some problem because any PC in my house recognize the 6.0.1 phone, but works fine with my up to date 8.1.0 athene, but it's charging only, and the turbo charging isn't working. the fingerprint isn't working neither.
It looks like the bootloader was unlooked, because everytime it's turned on shows the 'bootloarder unlock message'. But I was unable to root it, I tried all the one click root apps, but none of them worked.
It doesn't have any custom recovery, so I tried to update with the stock recovery but every OTA Blur Version rom that I found for athene shows a error telling that my ROM version isn't compatible with the updates (the ROM version code of this phone is MPJ24.139-23.1/ 1 user).
Anyone have any hints of what can I do to update this device?
Device XT-1640-DS
Android: 6.0.1
M8952_7000.04.03.32R
ATHENE_BRAZIL_DSDS_CUST
Kernel: 3.10.84-GCF01273
[email protected] #1
MPJ23.139-23.1
From what I know one click methods doesn't work with this device. You need a proper kernel for android 6.0 like elementalx 1.0. And supersu or magisk zip flashed through a recovery like TWRP.
Is there a way to update de kernel, or do that other things without PC and root?
Or a way to use adb without USB connection?
Have you tried fastboot flash methods like in this thread?
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
So.. the big issue is that this device isn't connecting to the PC, it's charges, but neither the PC not the Android show any signs that their are connected. I can't use adb from the PC because I couldn't make the computer recognize the phone.
can you at least transfer files in mtp mode with the usb cable? because looks like the micro usb port is messed up.
If you are on warranty period you should go for it
I can't use the mtp neither. The only thing I can do is charge. And I'm out of warranty :/
