Well its been a fun ride for the 8 series but from here on out I do not support or encourage rootIng this device. A good number of devices have become hard bricked from simply flashing the combo firmware. I don't know why this happens to only some phones possible a past OTA corrupted a partition on the phones or something. Whatever the reason I have decided to pull the method and will no longer support it. Please don't ask for files or help I will provide neither. I will leave rooted and non rooted safestrap roms up for those that still have a rooted 8 series.

Rooted Nougat Rom

This is last nougat rom made for S8 it is prerooted with flashfire and safestrap preinstalled. It has CSC stuff for all carriers added. Its debloated slightly with knox removed. Some stuff may not work but im not sure as I cannot test but this stuff may include fingerprint and or face recognition. If stuff doesnt work it probably related to using pie modems and non-hlos on a nougat rom which you have no choice.

Safestrap Method
If you didnt upgrade to V8 bootloaders using odin. I recommend flashing full stock firmware with V8 bootloaders even if you are already on V8 bootloader via OTA update. I feel that maybe something in the OTA from V7 bootloaders to V8 may have corrupted a bootloader file and some people have experienced bricks with trying to update to V8 bootloaders from V7 using the below method so I recommend flashing full stock V8 firmware in Odin before trying this method and just understand there has been a risk of bricking device. Full stock can be found on Sammobile or updato or any other service you can find it. You will have to reroot of course. If you Updated to V8 bootloaders using odin method already then no need to do so again

1. Extract system.img from the system_s8plus_brb1.7z and copy to phone also copy either SuperSu_System.zip or Magisk_System-v20.4.zip reboot to safestarp and flash system image
2. Flash either SuperSu_System.zip or Magisk_System-v20.4.zip
3. Reboot to download and flash BL_G955_NOUGAT_V7.tar.md5 in odin
4. If you get constant rebooting to safestrap flash Nougat safestrap zip while in safestrap

so if i remain at nougat i should be able to flash custom roms? Also, i'm currently facing "no service" problem on my g995u. Any ideas if going back to nougat would rectify the issue?

So what exactly happened?


Sent from my iPad using Tapatalk
i was on a g995u1 firwmare(bootloader v7) although i was having issues with "no signal". i thought maybe if i follow your guide to return the rom back to nougat my network would return to normal.
i only flashed this file "BL_ENG_BOOTLOADERS_SAFESTRAP_G955U_V7.tar.md5".

ps. i did tick the "nand erase" in odin.
the flash completed but my phone went black and did not reboot again.. i disconnected hoping to get it back to download mode again but nothing was working. i have tried using volume down and power keys but this only causes the a little part of the screen to flicker for less than a second.
my battery was 99%. I dont have qualcomm drivers installed. i am installing one as we speak, i have seen some threads with similar issues like mine but no solutions.. thanks for your response..:crying::crying::crying:

It happens once in awhile for no reason. Nand erase may have had something too do with it. I never use nand erase except if going back too totally stock from a modified system. I responded too your pm. You’re phone can probably be fixed with edl files but you are going too have too take your phone apart and jump some test points to make phone enter edl mode

I use to have pics and stuff but I lost them on a hard drive that failed. I can tell you they are on the bottom side of the board and you have to pry back a metal heat shield to get too them

You have to take board out and flip it over. The points are on the bottom side


Sent from my iPad using Tapatalk
OK, Thanks for the response. i see two large heat sinks with the larger one at the top and the smaller at the bottom. i assume the points would be hidden underneath the bottom sink. now i have to figure out a way to pry those metals off... so much work..lol..:D:D

Will this work on all V7 Bootloaders?

I am currently on DTF4 and noticed your on the Verizon page you posted for the DTB3 Bootloader. Thanks for your time and efforts.

This method is brought to you entirely by @elliwigy He is the reason for this exploit and method.
With that being said, Extreme Syndicate Root is now available!

Rooted Nougat Rom

Thanks this worked for me! Is there a guide on how to reverse everything if I wanted to make the phone normal again? Like it would be factory out of the box?

If anyone is thinking on updating phones now is the time. The method of unlocking bootloaders on US variants works one s10/s20 and n10/n20 phones. Read the whole article too get info and yes it works I have a bootloader unlocked sm-g975u s10+ with twrp and magisk installed.

    I updated the OP with new method that will hopefully cut down on certain phones bricking. I have no control over why certain phones brick when flashing combination firmware. Its most likely one of the partions over time has gotten corrupted.
