Ok so I went to flash twrp recovery onto my telephone and something went wrong while using oden... My usb debugging is turned on and OEM Unlocked. Now my phone screen stays completely black. Its caught in a bootloop and No buttons work to bring it back into download mode, Only Upload mode works.. Simply Odin will non flash anything to my telephone in Upload fashion. Information technology changes my samsung usb drivers to msm upload or modem drivers. I have been at this for weeks trying to go my s8+ to attach to my computer again using ADB, ODIN, SD CARD, AND EVEN THAT JIG Thing to force it into download mode only TO NO AVAIL.. I Have to some how get back into download mode but no push button combinations will work.. It seems to bootloop on me before it reaches those commands. The bootloader is evidently gone to a sure caste since upload way yet works.. Is in that location whatsoever fashion to use Odin in upload mode? Or is there whatsoever other way I can reflash stock rom to fix this issue? I have no recovery, no prophylactic mode, no download manner?? My phone is basically a paper weight right at present.. When I know All my stuff is withal on there. This S8+ Phone has put up a good fight with me on my pc But Im non one to loose. I love a good challange.. Whatever suggestions. I thought ADB Was my best bet only with no connect I cant do whatever affair. I deceit' get Adb to discover my device. Oh even tryed older versions of odin with low level quallcom drivers and that didn't work either. Odin volition read a com port to my device but i'm in the wrong manner (Upload Mode) and Odin deceit constitute a connection. When in Upload Way its the hellish 1 equally xda deveopers have said before..
S8+ phone is Model Number SM-G950U
Witch I believe has now been upgraded to SM-G955U OR F.. Simply I have the original stock rom still for SM-G950U if only I can go into some kind of Download Mode.
Ive even sat watching odin as I button every single button combination watching the ports appear and dissapear as it reboots trying to find some kind of style to download to the telephone... But no luck..

What revision bootloader was it on? I have several of them but not all
It was on its original bootloader for the Samsung Galaxy S8+ SM-G950U. It was SnapDragon bootloader
- #7
It was on its original bootloader for the Samsung Galaxy S8+ SM-G950U. It was SnapDragon bootloader
Mate at that place are 7 different revisions of the 950 u bootloader. Across all the software updates. No criminal offence intended. Only if you lot can't even give this little scrap of info I can assure you. Your non gonna exist able to dissemble this device. Ground out the exam points to enter edl. And wink needed repair files. Which is very ho-hum. If in that location is any issues. I would marker this device as lost and go another. I dont feel that you have the necessary skills needed to complete this process...

You lot are non in edl mode. You lot are stuck in upload. The only way to become to edl way is disassemble the device flip the motherboard upside down while hooked up. Ground out a exam pin on the mother board while connecting the usb cable.
