pretty sure the cache is in csc file.. the cp file should have adspso or something and modem.bin

i think anyways lol but yes, should b good so long as they dont touch the boot, recovery, devcfg, abl and system after root or else theyll have to start over most likely..

my process has been running great..

1) root with sampwnd

2) FF system.img and root zip

3) odin my custom package lol

- Latest U1 firmware, system.img removed, recovery, boot, abl and devcfg from latest combo, all the rest of all the other partitions from latest stock firmware..

makes it mostly stock with only the 4 combo files and rooted system of course

i also found a way to change the initial sammy splash screen and potentially a crap ton more but not successful yet as i am having trouble mounting the /param block device, i think its encrypted lol but i am 90% sure it holds the key to a bl unlock as well

---------- Post added at 12:52 AM ---------- Previous post was at 12:49 AM ----------

no.. u are on eng software version.. thatd cause ur problems especially if u used another csc then whats oroginally in sampwnd

you are showing g955u eng software with a model of g955u1 so i can only imagine csc is whacked out too lol

u basically want software to match model, baseband and csc.. it was in the disclaimers that root and such might not be stable on eng system which is why we highly recommend part 2

Ok I'm downloadeding the u1 latest firmware from right under a Sprint tower. When I do that I'll flash the system IMG which is the file? And then root file then entire cp? Or unzipped cp files? Then the bin? I'm sorry to be difficult

---------- Post added at 01:09 AM ---------- Previous post was at 01:06 AM ----------

So the firmware I'm downloading and root file, what else am I missing, once we have all files we can go from there. I'm jumping ahead

---------- Post added at 01:10 AM ---------- Previous post was at 01:09 AM ----------

Also I was asking if cp and bin come from the u1 latest or the samp

---------- Post added at 01:25 AM ---------- Previous post was at 01:10 AM ----------

I'm only saying all those because I did step 2 word for word and it apparently did nothing. Your telling me to flash some extra files which is fine if it's ok , but you also said follow step 2 , I'm just confused now is all
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] demalii:
After my img file failed, my phone went into panic mode constantly. I used Odin 3.12.7 to flash stock firmware. It failed at 32% giving me an error. I rebooted phone, it erased the stock firmware files, and booted up into a non rooted system. Since then, I have tried Odin Comsy and tried from the beginning to root all over.. It worked twice as I was trying different img files, none were successful, always putting me into constant panic mode.

While each flash of stock firmware with odin 3.12.7 errored at 32%. I used my newest stock firmware download on odin 3.12.3 . It still gives the 32% error and then erases files. Now, when I try to use odin comsy and flash the sampwnd files, after downloading, when it goes to install screen with the large circle and install bar in white-ish colored, it stops at 32% and then I go to reboot.. The "device RSA Keys, to authorize adb" screen no longer pops up and seems to still be stock even though loading screen shows the padlock unlocked etc like before when I rooted but panic mode when flashing the img file at end.

Was flashing so I could get out of panic mode..

Suggestions or ideas anyone?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
Wait wait...

If you want to fix your modem, just flash what I said don't do more. If you need to do a full os reinstall, then you need more things like system and reroot.

With the instructions I posted you don't have to reinstall at all

[MENTION=3812611]elliwigy[/MENTION] almost all firmware files have cache in them lol. They all install temporary **** that gets ran only to setup. The csc init stuff works that way. I wasn't including those
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] DetoxVenom:
So what do I do then, I thought that since my os and my model being diff also messes things up

---------- Post added at 03:15 AM ---------- Previous post was at 03:13 AM ----------

I also want to go ahead and update to latest so what files do I need, I'm downloading the latest AQ what ever xaa

---------- Post added at 03:28 AM ---------- Previous post was at 03:15 AM ----------

So

1.wipe

2.latest u1 firmware xt4

3.root.zip

4.cp from latest firmware

5.bin from bl extract

6.profit?

This will fix modem crash, give me latest firmware with root?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
1)Wipe

2)flash all at once:

- Latest firmware

- Root.

- Boot.img from the "fix your screen" thread

- Hlos

- Set reboot download

3) Odin CP, CSC, userdata if you care (you probably don't)

4) wipe / factory reset in recovery post Odin boot

Optional:

5) Boot normal, setup whatever you need install FlashFire

6) Take full system backup, keep in safe place

If your install works you will want a good backup to reduce recovery when it gets bootlooped by a bad zip flash or something.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] DetoxVenom:
The whole firmware.zip or just the xt4, also I don't have a computer I'll be doing this with flashfire only what ever it takes to stop my modem crash bs

---------- Post added at 03:42 AM ---------- Previous post was at 03:41 AM ----------

I need a exact guide with the exact files and exactly where to find them with flashfire only. I don't have a pic to use Odin right now. Thank you please

---------- Post added at 03:44 AM ---------- Previous post was at 03:42 AM ----------

If I need Odin to update to latest and keep root I'll do it later, so if that would be the case just tell me how to stop the modem error and I'll do the update later.

---------- Post added at 03:44 AM ---------- Previous post was at 03:44 AM ----------

Also the firmware download keeps resetting at around 70-90% wtf is the website bad this is the 5th time I tried.

Hybrid method

Just wanted to say first thank you guys. Second is I didn't quite this method. I did step one until commands in adb. I used root junkies automated program because for the life of me it wouldn't work using adb. It kept not exiting right. Or commands would not work and return data not found. Also in step 2 after getting the file on your phone, whether on sd card or external, you need to be in airplane mode for flashfire to even recognize the files. Weird stuff was happening before I finished. Even crashed the phone saying fatal modem. After a few tries(20-30) and researching some comments about root junkies. It worked. Been using it flawlessly. Also old if this helps but I got the phone to charge over 80 in airplane mode. It hit 83 percent a few times. Something preloaded by samsung is in the background. Other than that I have stopped all bloatware using my data and kicked my battery life into 2 days. Instead of maybe 8 hrs of run time. So who cares about 80 percent. It stays at 80 forever.

Knocked out by Knox

On the 2nd try I successfully rooted my S8, but then I went temporarily insane trying to rid my phone of Knox without doing the proper research.

The upshot is my phone is at least soft bricked stuck on the opening Samsung boot page. The only other mode I can get is upload mode. I have been unable to get the phone into recovery mode.

Not being very familiar with Samsung devices, my questions are: Can I use Odin in upload mode? If not what can I do to at least get my phone un-bricked and back to stock?

Thanks for any help.

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Shemploo:
So this happened recently - https://www.xda-developers.com/magisk-v14-receives-update-install/

...So you can provide your stock boot image (in both raw image format or tar-ed up ODIN flashable format) to Magisk Manager and it will patch it so that you no longer need a custom recovery to install Magisk.

https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

Thread notes:

Via Magisk Manager (Only support v14.0+):

This method does not need root, and also does not require a custom recovery.

However, you MUST have a stock boot image dump beforehand, and also be able to flash the patched boot image, either through fastboot/download mode or ODIN

--------------------

- With SamPWND are we able to flash a modified stock boot image?

- Does this mean we can get magisk running on devices that SamPWND works on?

- I did a search and it would seem we can't flash non-stock boot images?

This is a little beyond my realm of understanding, so I'm just asking questions.

Apologize if this is off-topic, it does not seem to me as such as we could possibly use SamPWND method to install Magisk?

Thanks for your patience :P

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] HighOnLinux:
1. Stop being rude to the others. Reading is highly recommended on XDA before you post and people have also had the same problem as you.

2. A process that could work (which if you read closely) is to restart the whole process over. As you need to download stock firmware, go on updato.com put your model number, download it and re-do everything from scratch. After you're on pure stock again, take out the SD card since you may be affected by that issue, and continue the process from there. If it doesnt work, then we'll try another way.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] txtimbre:
thank you. I am downloading the stock now, I'm just on a slow connection and it will take a while. You are right in that my sd card was in the phone when I started.

Rooted

AT&T G950U Thanks devs for all your hard work! Rooted yesterday successfully with pretty sraight forward OP. I got a lil confused around the setsid su, exit, mount part but as it says in the OP it can be a little tricky. For this part I went to the root junky video and it cleared it up for me.

Actually had to root again (i used the system.image from the AQGL firmware the 1st time rooting but the 2nd time i used the U1 variant AQDE) after attempting to flash the unofficial xposed and got softbricked it at the at&t logo.

I read on a different thread (unofficial xposed for s8+) that the U1 variant was working with xposed but haven't tried flashing xposed again. Realized the thread was for s8+ and I have the s8. Will probably wait for official xposed before trying again.. maybe lol.

Only issue is my phone freezes when I try to go into the Greenify settings but that is not a issue with the OP or devs lol
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Deliz8806:
I apologize I did download the AQH3 firmware (for the system.image) from updato but my baseband right now says AQDE. My build says AQGL.

Flash boot.img from aqi1 (see the thread under guides section) and flash NON_HLOS.bin from AQH3 in the BL archive under flashfire. This will bring your modem and boot/kernel up to latest supported versions and has been fixing screen issues and dramatically improving screen performance for many people. Ymmv though
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Deliz8806:
Am screenshotting and bookmarking thank you! Haven't had any screen issues as of yet but will do this tomorrow anyways just to be up to date. I appreciate the knowledge and advice ?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
Great! Hope it works out for you.

To anyone else in here having modem issues: apparently the NON_HLOS.bin is a radio firmware driver that also is used for parts of secureboot (my wild guess is due to hardware crypto modules) which (I think) is why it's kept in the BL archive and not the CP one. This means if you want your driver versions to match (you probably do) you should be sure to flash the CP that goes with whatever system.img.ext4 you flashed as part of step 2 and the NON_HLOS.bin from the BL archive that came with it.

Also if you are running a modern build with SamPWND I suggest taking a look at the AQI1 combo firm boot.img flash documented here: https://xdaforums.com/galaxy-s8/dev...-screen-corruption-fixed-t3673782/post7381240 as it has not only completely eliminated the "green screen"/other occasional garbled screen issues for many devices (and my theory is that fully updated system, modem, boot, etc all latest fixes it for everyone) but for myself and many others my screen looks a hell of a lot cleaner/brighter/better! I thought this was just placebo on my part and did not mention it until many others reported the same thing.

It has been recommended to also flash devcfg from the AQI1 combo firm (it's inside the whole archive file in the AQI1 thread) and abl.elf, but I have run for long periods with/without the devcfg change (and I don't see any major differences between the two) and both have functioned identically for me, and abl.elf is a bootloader which I would personally like to avoid updating, but it's definitely not an update that "increments" the bootloader so both are safe to do.

I've never been happier with how my phone is performing. Coupled with installing the San Francisco font (I'm not an apple fanboy, it just looks better than any other IMO) and I smile every time I unlock my screen.

(I'm happy to post a screenshot to show what I'm talking about if anyone cares but I didn't want to be presumptuous)
