No problem glad I could be of help. Yeah to much research can do that specially if your new to this. If your still having issues backup if you haven't already then reflash your stock firmware, you can get it from Updato.com if you don't already have it so you can start clean for rooting and fallow all the steps and use only patched odin. As for using safestrap it's pretty easy but if you don't want to go messing around like I like to do you can go on youtube and type in how to use twrp there should be plenty of videos on it.
[Samsung Galaxy S8 Guides, News, & Discussion] Zenak:
So I've been able to follow the instructions without a hitch. I am able to get Safestrap installed, and have tried two different stock system images. One is supposed to be the most recent June, and the other came from thethread linked in the OP - " ZSC2_SYSTEM.img ".

Neither of these boot, they both cause a kernal panic. I've been able to reflash safestrap, wipe cache, mount system, install images, and then reflash the exit file "BL_G950_DSE5_V5.tar.md5" .

I've done this a few times, and I'm not able to get the OS to boot.

Any thoughts or suggestions?

This isn't full blown root as much as it is a way to go back to oreo, which will be stock and no 80% battery issue. The only way o get true root will be to go back to a rooted N build then yes 80% battery issue will be there.

Handle is Invalid

Hey everyone, I have been at this for hours. Not new to ADB, Odin, or anything. But I am having serious issues with this for some reason. I flash the combination absolutely fine. wipe. boot into the binary... Run the reboot edl with no issues.. get a black screen as described. I look in devices and the device is listed as qualcomm 9008 (x-port) on any usb port.

However... when i try to run the Recover System, even as system admin I receive the following:

Failed to write hello response back to device

Did not receive Sahara hello packet from device

then it fails:

At the end it says:

Status: 6 The handle is invalid.

Finish!!

I have no idea what to do, I have reflashed via odin over a dozen times and keep getting stuck here... Any help would be appreciated

:confused:
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
My best advice is make sure latest drivers. And try other USB ports

Maybe re-download the file
[Samsung Galaxy S8 Guides, News, & Discussion] Iration_Sti:
latest drivers are installed... redownloaded this file twice... windows defender off, and whitelisted the folder just in case. Every time, Every port, Every restart... its just not seeing it even though it shows up as qualcomm (port x) in every one. everything is good until this step.. and it just cant connect to the phone for the final recover system push... and I cannot fathom why...

I also have tried to download an odinable firmware, 3 of them... to at least get it working again... and now that failing. ugh :crying:

[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yes. Normally that would be a driver issue
[Samsung Galaxy S8 Guides, News, & Discussion] Iration_Sti:
To anyone else who has the issue above!! The Fix was disabling Driver Signature Enforcement. Having the Qualcomm drivers from an unsigned source caused the issue. Disabled by restarting the computer into the start settings and hitting f7 for disable driver enforcement. works like a charm now :) Cheers

Hey if a man was hard bricked rev 5 already in edl could he repair his device by using your root method alone? I was thinking about this at like 5 am this morning. :laugh:

BTW I'm no more on Samsung. My s8 broke. The R-Just shockproof case isn't very shock proof. My s8 fell off my bed onto the carpet in between hair the bedrail. The case is designed the glass never touched the metal rail. It shocked in the case and hit the aluminum frame of the case and shattered my screen. I fell like raising Cain with the company but I know it won't do no good.

Worked! Although when trying to downgrade flashing dream rom and v2 bootloader I bricked it. It is stuck in edl mode, buttons not working. I'll try to bring it back after it runs out of battery as a "manual" restart, because right now my pc recognizes it but it can't connect, the recovery script gets frozen.

Worked, right now I'm flashing again. Just in case someone has the same problem, wait a day and try to run recover script again.

With plugged into pc. Hold all buttons. You will hear it disconnect and reconnect on the PC with sounds like USB device.

If ever a failed flash in edl you must reboot edl mode hence why it worked after a battery drain too I've had to hold them sometimes like 10 15 seconds.

Hello,

My Samsung is a S8 G950U1 with android version 9.0 (Pie). Does your method work in this version?

Does it work on any version of Bootloader? How can I find out which version of my Bootloader ?

Thanks.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
5th digit from far end of firmware. This is for revision 6 as stated. If you are lower it will update your bootloader. If your on pie. Your 5 or 6 This is not root for pie either
[Samsung Galaxy S8 Guides, News, & Discussion] dewbieZ:
Got to step 5, now all I have is a black screen on bootup. Shows Galaxy S8 powered by Android, and thats it.

When I get back into Android Recovery at the bottom it says

E: unknown volume for path /odm

E: unknown volume for path /vendor

This is where I hit wipe data/factory reset. . .

Just sits at black screen.
[Samsung Galaxy S8 Guides, News, & Discussion] raitos:
Got it, thanks for the info, my version of bootloader is 6!

But my android is Pie, is there any way I can root it? Maybe a downgrade or something ...
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
What this does is install safestrap. You can then flash one of the few nougat ROMs and respective bootloader that's also revision 6. There is a combination bootloader for nougat that is also rev 6 so you can sport rooted nougat and or pie. I don't know if there is any way for oreo on rev 6 since rev 6 was released for pie
[Samsung Galaxy S8 Guides, News, & Discussion] dewbieZ:
So I think this is where I'm at. I can't seem to locate a V6 bootloader version of nougat for the 950U. I was able to get Safestrap installed, but when I do

5. "In odin load BL_G950USQS*****.tar.md5 in BL slot and HOME_CSC_OYN_G950U_CACHE.tar.md5 in CSC slot and flash when done phone will reboot to recovery"

Nothing happens for me. The initial splash screen turns on, and then everything goes black. Am I supposed to put the CSC.tar in the USERDATA slot or the CSC slot, as of now I have only tried putting in the CSC slot and it's not working.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Csc goes in csc slot. If you can find the combination rev 6 file the boot imge will boot nougat system files. Do not flash a older boot imge. Rev5 or lower. Only system can be flashed. You've got a wrong boot img matched with wrong system more than likely. Til you find the revision 6 boot img for nougat it will not boot either
[Samsung Galaxy S8 Guides, News, & Discussion] dewbieZ:
I used what was provided in the OP for the REV 6 bootloader option. So now I'm stuck with a bricked phone that won't boot the stock PIE image?

For the slow sites, I recommend using a segmented FTP downloader like LFTP and run pget -n 28 <filename>. LFTP will work with http:// links.
