Hey Guys, I usually root my Android devices - but I left it this time but lot of things need it however I use Samsung pay - Ive heard Magisk method ( which lets u use Samsung pay ). Is there any update from the OP? or can anyone tell me how should I proceed
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] cdakaharpo:
I wanted to make a post here for anyone who comes across the issues I had. Hopefully this will help instead of searching through the almost 200 pages here. SM-G950U Verizon S8

Search tags:

Subsystem crashed modem

Can't get passed the initial odin flash after phone reboots

Crash after boot Crash after initialization

Subsystem crash randomly after set up

So I messed up when I originally had successful root and had to flashed stock. After this I could not get this process to work. Every time the phone would start to boot after the odin flash and crash immediately after / during initialization.

Here is what I did. Feel free to PM me if you have questions.

From stock firmware, I placed the phone in download mode. With comsy odin (S8 version, not the s7 version from this OP) I flashed the 4 files with auto reboot, re-partition, nand erase all, f reset time, and phone bootloader update. It crashed at initialization with subsystem crash modem.

I then booted the phone back into download mode, flashed the stock csc only with normal odin. At this point it still crashed again at the same point but after booting into RECOVERY, I did factory reset and wipe cache and pulled the SIM card. Yes the SIM card not just SD card. This is because I noticed this crash would happen as soon as the LTE would kick on.

Finally it booted all the way! and I was able to use the 1 click method from the S8+ thread. https://xdaforums.com/galaxy-s8+/development/root-g955u-g955u1-snapdragon-sampwnd-t3658911

I kept the SIM card out until I had completed the stable build. I will get into the stable build I used.

Now that SU was working and Flashfire (I used the one from the play store) I was able to follow the samFAIL method from the flashfire instruction part (You will see this part is near the end of the samFail OP).

https://xdaforums.com/galaxy-s8/development/root-partcyborgrom-aqi6-deodexed-t3702988

And after this I reinserted me SIM card and all done! Hope this helps. If you feel you have a stupid question please pm me so this thread doesn't continue to get filled up with repeat questions. I'd like to see this thread stay active and not get closed like the S8+ thread. Good luck guys

Can anyone help out please ---------

Mistakenly deleted "Camera" folder in phone memory from gallery. Tried bunch of recovery tools and end up requiring root to recover deleted files. Current available root method wipes the device making it impossible to recover. Is there a way to root without wipe? or Is there a way to recover without root? Please help.

Current Firmware: G950USQU1AQGL
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] cdakaharpo:
All root at this point will wipe.

You can use a computer and download an app to recover files while your phone is connected. Just do some research...google how to recover files off of a damaged external hard drive or phone. Should be able to find some info. In the mean time try to limit downloading any files of your phone or take pix as this will write over the "hidden" files that got deleted
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] rsesham:
Tried some apps and some PC softwares, was able to recover pics but couldn't recover videos. For me to recover the videos, those apps/pc softwares require root.

Not using the device since then - until I figure out a solution on that.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] cdakaharpo:
Interesting....that shouldn't be an issue considering smart phones are basically a little computer. If you can get to your pix you should be able to recover videos. Let me do some googling and I'll PM you if I find anything

But I haven't checked yet if the kernel is permissive or enforcing (shell root -eng or non-eng).

So, if someone wants to try to root it somehow then "dd" dump the entire system (/dev/block/sda19) which should be SamFail method flashable?!

doesnt matter really on permissive.. its dm verity u gotta look for

---------- Post added at 01:21 PM ---------- Previous post was at 01:19 PM ----------

and to add, no... lol doesnt work that way.. u need to carefully craft a rev2 stock firmware with root similar to original samfail.. the combo parts not modified technically

---------- Post added at 01:23 PM ---------- Previous post was at 01:21 PM ----------

lmaooo.. u probably updated to rev2 and tryna downgrade.. either way u always take risks attempting to root especially with SamFAIL

Removed my rant. But still annoyed that Google can brick a perfectly legit phone.

I was able to unbrick and actually got a successful root based in part on the 1 click.

I had to mix the "old way and files" with the one click and it worked.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
So I got a possible unique ? Followed all through the guide. Everything's good,got root, Even use apps ad able to grant su permissions but When it comes time for the actual root operation, Be it delete a system app, file or folder,

Even root checker I grant su but just sits there saying acquiring root access...

Some apps tell me Im not rooted

I got the xfinity mobile S8 on U1 firm of coarse..
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] elliwigy:
not uniques.. by chance did u go through second part? it sounds like youre still on eng firmware

I remember reading about the one click mentioned in a comment earlier in the thread by somebody and wondered the same thing myself. LOL

I just figured there was some special reason why it wasn't.

Too lazy to read 151 pages of this one tonight. Lol Is Timeless even actually aware of it?

I was following this one pretty consistently in the beginning but since Sam fail and PCR I've kind of fallen off keeping up with it to be honest. LOL

I used the files from the old version of instructions coupled with the 1 click.

The files that are part of the 1 click write up failed miserably on my phone 950U.

But the script was genius. It 100% worked even with a mix of intended files.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
What do I do if the system img is over 4 gb And dont want to transfer to my card?

Hey guys, i have the tmobile S8 and Odin prince comsy keeps failing when trying to flash the firmware files. Any ideas?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] nytebird:
I want root for my 950U Just came from 1+5 still have this was a gift can you point out which files you re talking about and the steps you took to get root? Otherwise I'll wait for the aqk2 version Thanks in advance Don't want to brick!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Stheno:
I followed the instructions in the post mentioned later on "root-g955u-g955u1-snapdragon-sampwnd-t3658911" completely and used the SamPWND_Root.zip.

The other files I used are from the first post in this thread.

More details as to how I utilized these files as I extracted and moved things around a bit:

In the instruction post here: https://xdaforums.com/galaxy-s8+/de...on-sampwnd-t3658911/post73455548#post73455548

instead of "Initial ODIN 4 Files FIRMWARE" I used the "SamPWND_S8" zip contents. (4 files).

for the "system.img.ext4" I extracted that out of the AP file in the previous zip.

The file I am unsure of where I got it on these forums I am pretty sure I renamed it in my previous attempts at failed rooting.

But on my drive it's name is "SamPWND_G950U.zip" and is around 120mb I used this in place of "QG2_ADD_CSC_SYSTEMROOT.zip" (the one I used is a couple mb smaller than the QG2 one)

I think it came from a SamFail post. But it looks like it has since been edited and the link to old files are gone?

If I figure out what/where that came from I will update this.

But I followed the instructions exact just changed the files. I also copied the SYSTEMROOT zip and the system.img to the internal drive on the phone, NOT the sd.

On reboots it took a LONG time to boot. It looked hung, but I ignored it and did other things and came back to it booted.

My baseband version shows "G950USQU1AQDE" after all is said and done if that helps any as well.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
I only had that issue when i tried playing around with build.prop files to where i attempted to make the wifi passwords unencrypted for my own sake. Turned out to be a whole mistake, and had to manually re-enter every password on each reboot. But was there a certain thing that you did or did it just randomly occur?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
Nope. Happens rite out the gate. Every time.

Now I did do the build prop edit this time to see i it would work.... It most def did not. If anything made it worse. I reset build prop back to true on ro.securestorage. and have not had it happen since. Even reboots. Still got wifi...

This Xfinity device has been real tempramental right from the gitgo...
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
I feel you on that one. I honestly don't have a solid solution onto fixing that issue, but you did what i did and it still happens. So well what i did was just factory reset everything and it rarely occurred. But results may vary.

Straight Talk (Tracphone)

I have a straight talk s8 that I need to root in order to recover some deleted data on. If I follow this procedure, will the recovery tools still be able to recover deleted files? Thanks!
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Stheno:
I'm not the most knowledgeable in this process, but I'd think the action of actually rooting would render deleted files unrecoverable.

Rooting writes over not only existing files by clearing the storage, but writes over blocks that deleted data resides on.

I am not sure of how feasible an after the fact rooting would be in recovering lost data.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
They would be gone forever as this overwrite a lot of data you can try diskdigger it does ok at recovering and does work without root

By 1-step root are you referring to the bat file mention in OP at step 2 or another method. I've been googling this method and don't know if sources I'm finding are valid or not. It appears to be a windows program? Trying to root now but Odin is failing. Thanks

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] klark1kent:
Hi. Yup. Comsey...its failing before flashing anything: odin sw rev check fail abl fused 2 binary 1. Also tried standard odin

Maybe I need a different firmware package that's in line with my current one of G955USQS2BQL1

I've used odin for root etc before but not since samsung s4 so my bad for ignorance... previously had LG v10 rooted so not a total moron given that device had difficult to achieve root. Any help would be appreciated
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
Its a bootloader issue your firmware sounds like its on the u2 bootloader and what you are trying to flash is version u1 of the older bootloader

Bassicly you are failing a Anti rollback check

So yes you need a "new" or "Updated" firmware

Also I would try the samfail method it is flashable in Odin also provides a U2 bootloader at worse you have to take your stock firmware and flash the CSC But thats only if you have any issues after flash
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] tangoboyz:
OK asking some advise? I have a Baseband G950USQU1AQG4, never accepted any updates since purchase. Should I follow the process in this thread as I'm still on the U1 bootloader right. OR should I take the update to U2 and follow the new process.

I just want the easiest way and after reading over the last pages it seems people are struggling with the this process.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
As of rite now the only thing with U1 BL is normally if a "hack or exploit" ever does come wich I am not saying it will or won't Is that usually time has told that lowest Bls and Firmware get the root and unlocks first. But the way things are going just like on LG No unlock will be found for a long long time....So As of now in my opinion the U2 PC rom is the easiest and least bugged way to go... Again IMO

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] klark1kent:
**** I thought I had U1 bootloader this entire time and ruled that out as a possibility. I'll do some verification on BL and check out samfail. Thanks dude. I never thought I'd miss basic root capabilities so much but Jesus it's amazing what basic stuff you can't do without root

The reason it won't charge to 100 is it is set in the Kernel which we cannot modify due to locked bootloader. It is not a bug. It is how samsung designed their permissive kernels
