Thanks for your hard work! I am new here so I have some question to ask you. Is the 80 percent battery bug is still present in this method?And where can I find a flashable rom that safestrap can use? Thank you:)
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yes it is the combination bootloader used to get root and permisive has this safety feature implemented. I would assume if you flash 8.0 or 9 since they use diffrent bootloaders then no but if you flash 7.0 and root then yes

Have SM-G950U (at&t carrier?) what would do after downloading everything, have BLv5, and..... thats about it (you have instructions but im not fully trusting in my understanding of what to do)

could you give more step by step instructions

last time doing this was with a s5 a couple years back

sorry for inconvenience
[Samsung Galaxy S8 Guides, News, & Discussion] SamGuy2020:
I'm guessing you can probably install this but not sure what to do with it after words.

Basically, you can go find amother one of his roms he poosted link to (oreo or pie safestrap, none-rooted) or you can install PartyCyborgRom (Nougat root) but to install any of them you have to extract the system.img.ext4 (rename it then to system.img) from the AP of any of those ROMs and fllash it in safestrap (make sure to change from install zip to install img). I you chose any of the oreo or pie roms use the BL file here to follow the instructions on those threads to enter/exit safestrap. As of now there is no active root for oreo/pie. Safestrap gives you the ability the modify the system without root. A rootless customized by yourself rom if you will.

[Samsung Galaxy S8 Guides, News, & Discussion] R-T-B:
Hello all.

I also posted this in the Galaxy Note 8 forum, but there is some crossover and I figured I'd consolidate our efforts as the devices are similar firmware wise as far as the locked bootloaders go (or so it seems). They also had a lot of bootloader related research, which I used to supplement my own knowledge of the qualcomm bootstack.

I'm coming from LG land where I helped in the G3 era with qualcomm debricking stuff. Was pretty famous for it back then, but a lot has changed! Most of my work is sadly not here at xda, but known externally in the cellphone refurbishing industry.

At any rate, I have some knowledge of what to look at and this and other threads have supplemented that knowledge. I began playing with devinfo partition on a v5 bootloader as it seems no one ever really tried that. I got the following after setting and unsetting a few bits:

https://img.techpowerup.org/190310/unlocked.jpg

Download mode still says secure boot is enabled, but the "unlock" symbol has me hopeful. Am I onto something or did this "Knox" I keep hearing about just notice me? lol

When flashing my verizon stock firmware, the unlocked padlock symbol is maintained. Anything to this? How would I safely test if the bootloader is truly unlocked?

Sorry if this is a really noobish question, I am new to samsung devices.
[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Once you flash stock firmware and reboot the unlock symbol will go away. You didn’t discover any miracle unlocking

[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I have got the padlock down to being i yhink a eng modem or not. I was flashing my cp file ealier and it seems to have replaced my padlock back without.

My days started back on lg g2 had the g3 g4 and g5 but have had loads of sammies in here too.

These bootloaders are signed with a 256 bit sha key.

There not technicly locked. There are loads of us who have looked into each revision of bootloader. And i know the comment has been made several times. Just like with some of the lg g4s. If and ever a unlock comes our way more than likely through edl mode.
[Samsung Galaxy S8 Guides, News, & Discussion] R-T-B:
I mean, as I stated, it doesn't. Need proof? I think I'm onto something here. The bytes that appear to control unlocking are the same as EDL qualcomm source. The differene is surpsringly trivial... Samsung padded the "ANDROID BOOT" string with two 01 01 bytes that appeared to block their reading. Settings those to 0 enabled the standard unlock flags, if what I'm seeing is real.

Again, don't mean to trivialize your efforts at all, because I have a lot of skill but it's not specific to Samsung. I have absolutely no idea what to do next to test if the bootloader is unlocked short of doing something stupid that may risk a brick.

Phrased another way, what partition should I modify to test this that won't break download mode and SHOULD fail to boot if we are locked?

Again, my knowledge is dated, and I'm afraid the usual tricks may not apply anymore, so I'm double checking. I'll be happy to share my work in exchange.

EDIT: And I fully acknowledge I almost certainly don't have anything for the record. It's just an exciting prospect. Do you guys have a dev channel or something so I can help and not repeat what's already been tried? Forums are somewhat confusing to wade through.

---------- Post added at 06:46 PM ---------- Previous post was at 06:38 PM ----------

This unfortunately looks to be the case (the modem). damn.

You guys have a place where devs hang for this phone? I'd love to join in. I have some old skills but they are skills all the same.

It did seem improbable no one would have played with the devinfo partition... but man, I like to dream... lol.

I got a telegram group with a few of us most of the time its more off topic and junk but every now and then we get something going.
[Samsung Galaxy S8 Guides, News, & Discussion] R-T-B:
I'm mainly looking to not repeat what's been attempted already. If I could just pick the brains of some people who have played with this phone it'd be infinitely helpful.

My ultimate goal is more broad than most. I want a full bootloader unlock or something close to it in end functionality (ala LG G3 "bump" type stuff). Root alone will not satisfy me. And yes, I know my phone is probably going to end a brick but I want to try all the same, heh.

I've used Telegram, but have no idea what my account name or number was. I will see about setting something up if you don't mind inviting me.

Does anyone know if this triggers Knox? Just curious, already started.

Up to the Recover_System.exe

First attempt only had a flashing yellow cursor after 50 minutes. Restarting step 4

EDIT:

I meant to type Recover_System.exe

Update:

All installed great.

How I got past Run Recover_System.exe issue

I initially I got stuck on Step 4 (Run Recover_System.exe) with the blinking cursor, possibly because Windows Security antivirus kept deleting it, even though I disabled it. So, I simply added the folder to the exclusion list. I also rebooted the laptop, since I had to [auto]install drivers in device manager (for Qualcomm 9008, I believe.) Once I did that, Recover_System.exe immediately started writing the sectors. :D

Thanks so much for the thread and everything you've done to put this all together! As well as for the reply.

Followup question:

If I use SuperSU in the factory binary, would that trip Knox? (If it works on snapdragon SM-950)

Trying to get as far as I can, without tripping it. Then again, there's always the option of weighing the pro's/con's, if I need to.

I have everything installed, now onto loading oreo and pie in the slots. As well as, learning how to use SafeStrap/TWRP.

As a bit of a noob to SafeStrap/TWRP, I wondering if someone could help or link me to the info. I did some googling, with no resolve. I installed this root, (backed up) then did the linked Oreo rom.

I've read over time, including months before I installed this, that you could create virtual rom slots. Is this still possible with SafeStrap v4.07?, or do I need to try the v4.08 beta? I couldn't find boot options to click on.

I would ideally like to have rooted nougat in 1 slot, to edit files (in EFS, etc.), use root features, etc. As well as, Oreo and Pie in slots 2 & 3. That way I can just flash a bootloader, and access that firmware. I assume the EFS files I edit will be able to be used in Oreo/Pie?

Thanks, you just saved me a lot of time, trying to figure this out. I can give up my futile quest.

Is there a way for me to edit HiddenMenu in /efs/carrier, and have it work in your Pie rom?

When I try using the file manager within SafeStrap, I can't view anything in the EFS folder. I was able to view it within the original rooted nougat "factory binary" (7.0) you included.

I'm trying to enable the [VZW disabled] hidden menu (via dialer) AKA engineering menu, system menu, service mode, and a million other things I've seen it referred to as. ie. The menu's you'd use codes like: *#2683662#

Even if I can't have it stick in 8.0/9.0, using a rooted nougat might be worth it. If, I can enable 4x4 MIMO, 256QAM, various CA combos, connect to specific LTE bands, and edit LTE cat speed (S8 has an LTE cat16 modem, but some forums said it was set at LTE cat9, with cat1-cat10 being the only options.) From what I've read, Samsung and Verizon disables many of these. And YES, I do know that the towers need to support these, that it won't magically work otherwise
