I don't know if it'll make any difference, but I have one last idea or 2. I have maybe 25% faith either will work.

If you can both get into the OS with flashing certain files, of mixed versions as you can't flash CSC. To check which CSC is installed using the dialer codes (I can look up from the semi-extensive list I made), then flash the other 3 to match that CSC. Once they all match, to then try the Verizon app again. I know the phone it's won't install OTA updates if you have mismatched files (I've done that on purpose to prevent upgrades). But, I think the VZN app could really care less what's actually installed on the device, as I've used it after getting that BSOD telling me that I modified it, and needed to bring it to a carrier and pay them to recover the phone.

My 2nd grasping for straws idea, is if you believe the cache is corrupted. To extract the cache.img from the full stock firmware version you flashed above, and flash that within safestrap, if you still have access to it (or if you think it works, to have one of us upload our cache via safestrap from the same version, if it's compatible like that??) . That being said, I don't have any experience with ever having needed to effectively flash it.

That being said, both of you seem to have a more extensive knowledge than me. Especially if one/both of you are jumping the mobo itself for the EDL test points, among other things you've tried. So, I'm sure you either already tried both of those, or didn't think they would work at all. I just figured brainstorming couldn't hurt. I've pulled many hail mary's from ideas I had zero faith in, and only proceeded out of desperation.

Also [MENTION=5759239]TheMadScientist[/MENTION]: I don't know if the deal is still active, or if it's still worth it on such an old phone, but a couple weeks ago Sprint started a $49 screen replacement deal, regardless of if you were a customer. I can check the deal thread if interested. If it was an S8+/Note 8, S9, S10, It would definitely be worth it. I didn't bother on any of the S7 edges I have with broken screens (I purposely purchased them for $38-$55 over the past couple years, just to use as a wifi hotspot). Nor did I do it on my S8, since it's an old phone w/ some cracks in spots I don't touch regularly, and in the corners that I colorless/clear epoxied well...with no OLED damage at all.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
The sprint deal I think ended yesterday.

I might buy see if I can buy the edl 7 files I updated mine today to bit 7. Xfinity 100% stick still the same I'm not hard bricked but it will be. Like I said mines just a junker sitting there. I quit trying to modify my good one as it's my daily for now. About time to upgrade. Had mine for 2 + years now. New battery perfect time to sell it
[Samsung Galaxy S8 Guides, News, & Discussion] Sagoode:
Are they available now? I can contribute if you get them.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I don't know. I thought one said they was for like 20 bucks
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
I was using that as a universal price, since that's what people say they normally cost, in various threads. You should check the Note 8 (N950) thread, and possibly the S8+ (G955) threads, as someone said they could get the files. The reply chain in that thread went as far as seeing how if jrkruse would create it, and he said yes. Along with all the details in between.

According to the what they said in that thread, the V7 EDL files were available for that device, so I assumed the S8 would also. I had googled it earlier, but never clicked the links. Clicking links now, seems mainly to be just fake sites (ie. just text dump, spa sites with text dumps, etc. Sorry about the ambiguity with my earlier comment about it. I assumed it was available. Maybe you can have better luck w/ the keywords you google, or ask that guy from the other thread, with friends at samsung.

So far I found a site with bit 7 combo file for $4, but haven't found EDL yet (unless EDL is in the combo files. I have minimal knowledge of the technical side of combo files)
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I will look after while. I posted up a bit 7 combo file. I got ahold of that one. Half the battle. ??? I got a few reputable sources that can get edl files and junk I'll ask em all again. I don't mind paying for em unless they are like 100s of bucks. ??? but if they are like 10 to 30 bucks I'll most def throw down. I saw you post it and was like screw it I'm down. But we will see. No probs man. We will find it eventually. We always do. Normally about the time next bit comes out is when the one previous is found or released
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
I assumed the EDL wasn't part of the combo files, but after not having luck in my first quick attempt, it got me questioning myself.

I'll google EDL files when I have free time tonight. Hopefully I'll have some luck w/ better search terms. If both our methods fail, you could always reach out to the guy in the other thread...the people on this site always seem to help each other out, which is amazing. The combo files are a joke to find online, if only EDL was that easy
[Samsung Galaxy S8 Guides, News, & Discussion] banny21:
there is a lot of conflicting information in your post. Can you use this method to flash lineageOS on the SMG950W version?
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
Where is it conflicting about lineageOS or the W?

Did you use the search function?

Please quote these posts, and I'll be more than happy to help you answer it
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
As stated. No. Lineage is a custom rom. which requires unlocked boot loader. The g950 U U1 and W are all of the same model. Which are unable to unlock bootloader. You can root depending on which bootloader you are currently on. In build info. 5th digit from far end is build revision. 1 through 6 are currently rootable. 7 may be in the future but right now it is not.
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
Bah! I wanted to see this supposed conflicting info. Or to at least educate about the search button.

The thread was full of so many posts saying it's impossible. Even sarcastic jokes pretending to ask if it was possible [often w/ emoji's], as it was approaching the equivalent of meme status. Since no one ever searched or read past replies.

Will the "Make Your Own System Image" part work with a bootloader version 7 firmware? Just wondering, since all of these Samsung firmware sites are a pain in the ass to download from and SamFirm only gets the latest firmware :/
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
As for what? The make your own system img I believe is a 7.0 system. As of right now there is not root on a bit 7 firmware. So you couldn't even flash the build your own. If we had the needed files for root. yea it would
[Samsung Galaxy S8 Guides, News, & Discussion] evilarceus:
Meant for this:

Could I use a system.img.ext4 from a firmware with bootloader version 7 (which I assume is what you mean by "bit 7") in these steps, and install it on an S8 installed with Safestrap? Just asking since I don't know if there would any incompatibilities due the bootloader version mismatch.

(Basically: will downloading G950USQS7DTA3 from SamFirm, extracting and flashing system.img.ext4, and then flashing G_950_PIE_ROM_CREATE.zip work?)
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yea. The systems are not incremental like the bootloader is. Should work just fine.

[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
1st Question, do you already have safestrap installed?

If not, the safestrap install process hasn't been created for BL7 yet, due to a lack of v7 EDL files.

If you already have safestrap installed, then proceed.

I thought the rom creation tool didn't work on newer versions?

When I failed at creating my own bit 6 U1 system.img using this method, jrkruse had said it didn't work on BL6. I had assumed that he meant it only worked until v5 (or possibly prior)

For that, I was instructed to use SuperR's Kitchen to create my own system.img using the stock firmware. Something I still had issues with, and will need to revisit when I have time.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
**** that's right. I never used it. I always did my own system img then added root and junk after.

[Samsung Galaxy S8 Guides, News, & Discussion] sawixso81:
In what order did you get your partycyborg rom running, I have a prerooted BRB1 with safe strap, tried to load that and flashed in safestrap and rebooted. I am still on the BL_SAFESTRAP_V5 boot and it just hangs still, now my image I did, copy from pc to sd card while in safestrap so maybe my .img is corrupt it did copy over quit fast for almost a 5 gig file lol.

oem unlocking?

Hi, thank you for this method. I followed your instructions and everything seems ok when booting. Now, When I hit continue it takes me to a blue screen with yellow letters that has my version info is this correct? or should my old stock rom be on there? Another thing I found in settings, developer options is oem unlocking. Couldn't this be used to find an exploit for full unlocking the kernel to give us g950u owner full root access? Thank you again.

It tells you in description that it flashes stock rooted combo rom. From there you use safestrap to flash one of my oreo or pie roms or some of the prerooted nogat roms available. There is no way to unlock bootloader the oem unlock just removes FRP

Hello everyone, i am currently on BL7 firmware and just want to downgrade to BL5 firmware on SMG-950U1, will this process help? because somewhere in this procedure i read zeroing the bootloader (an opportunity to install BL5) and if it is possible please help me with the steps to do so and thanks in advance to whoever brings-in the required files for BL7.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
You cannot downgrade bootloader's. They are incremented. Just because you zero out the bl doesn't allow. The incrementation is stored elsewhere. And none of this works on bit 7 yet as we do not have the needed edl files for it
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
No.

Although you have the ability to change firmware/software, you don't have the ability to physically alter your chips.

Samsung implemented e-fuse's a few years ago. Whenever you update to a higher bootloader version, the chip physically blows one of those fuses. This prevents you from installing a previous BL version. So unless you're really skilled at soldering a miniature connection that just blew, you're SOL.

Chances are that you'll be able to use the rooted android 7 (nougat), once a method for EDL BL7 comes out. So, do your best to find the EDL files for BL v7, and I'm sure some of the others will split the cost with you. JRKRUSE will create the files, once you get him the EDL files for bit 7.

---------- Post added at 04:15 PM ---------- Previous post was at 04:08 PM ----------

Your only hope at this time, is to buy a mobo off of ebay for ~$50. With broken screen phones often being cheaper than the mobo itself. That being said, many sellers will not tell you the BL version, as I assume most of them just drop ship or are just really lazy. Generally the broken screen ones have pretty old bit versions, as they haven't been used in forever. Worse comes to worse, if you get a broken screen one cheap enough, you can resell the mobo for a profit/break even. And since you can change the "model" of any snapdragon variant by flashing different firmware, it boosts your options and drops the price.
[Samsung Galaxy S8 Guides, News, & Discussion] prayag00:
Thanks for bringing upfront the efuse tech but i think i really like the response of phone when it was on bl5 firmware, it would be very appreciable if anyone guide me down to get that flawless os build. And now my aim does not involve changing BL but the system (AP).

[Samsung Galaxy S8 Guides, News, & Discussion] prayag00:
I guess Oreo to Pie transition took place within BL5 updates on SM G950U1 which means ( according to your quote ) i can load pie firmware (AP,CP) from bl5 firmware with current bl7 file, the only condition here is it should not be Oreo.

US Phones

Hey, first of all, thanks for this root method. I've been waiting for one for so long. Second, does this work on all SM-G950U phones? Even ones on the T-Mobile carrier in the United States? I just want to check all the boxes because I've been under the impression that S8s made for US carriers can't be rooted. Sorry if I sound less than intelligent on this subject. I just really don't want to mess up a device that's this expensive.

Edit: Just realized I'm on BLv7 so even if I wanted to root there's no way to at this moment unless I'm mistaken.
[Samsung Galaxy S8 Guides, News, & Discussion] Sagoode:
You are correct. Hopefully we get the files need one day, but unfortunately for now you're stuck with stock.
[Samsung Galaxy S8 Guides, News, & Discussion] sleepysys:
Yep, any snapdragon variant. That includes USA variants, as well as other countries including Canada. The hardware is physically the same, with the only difference between these snapdragon models, being the firmware placed on them. Just like how with the S7 edge, you could change the SM-G935V to a SM-G935U, etc.

As for root, with this method it's possible to have nougat root (android 7). For Oreo/Pie, it's more like a semi-root. Meaning that you won't be about to use super user or any root features from within the OS. However, when you load into SafeStrap, you'll be able to add/delete/modify any system file you choose. Such as build.prop, the hiddenmenu file to enable dialer codes on verizon, etc. You'll be able to install mod zips, safestrap roms (system.img), restore backups of your entire phone or parts if you choose, as well as make the backups There's some other things you can do, which I mentioned in previous posts, as have others. I just can't think of the rest of the top of my head.
