Anyone had success with T-mobile USA S8? SM-G950U1
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] FuMMoD:
Confirmed working on my S8+ on tmobile. Just need to flash the modem file from the tmobile firmware. I think it's called the CP file. Besides all the app crashes it's working perfectly and smoother.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jongcruz:
Thank you so much for the information, I'll have to try with my S8 and report back! Does your battery reach the 100% visual battery?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] FuMMoD:
No one's does unfortunately. This is what we're trading in order for root. For me it's a decent trade off. I still get great battery life and if anything I have a powerbank or a charger easily accessible.

Really? Good to know
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] hazmad:
IDK dude, you keep having modem crashed no matter what you do. are you sure you're using the right system firmware? Maybe you have a hardware problem, or you're doing something funky. Do you still have this problem if you go back to fresh stock? If you're stable on fresh stock firmware, then try odin flashing sampwnd AP and BL (without non_hlos; copy BL file, remove non_hlos.bin). after reboot Odin CSC_OYN, if needed. If it's not stable on stock, maybe try an older firmware. You might be stuck with stock, if root's not working.

If you still have problems after all that, then I'm all tapped out. Maybe use the warranty, maybe just burn your phone in a blaze of glory. /s
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:

It's stable on stock, idk either it's really starting to piss me off tbh.

Something is up, I just noticed I don't have WiFi calling, and all my little cache like data is there along with some of the stuff on my internal is still there, does that mean that flashfire didn't wipe anything?

There was an issue even on stock with sdcards. There are huge threads on the Samsung support forums. They released an update in June that specifically mentioned improving sdcard stability. Perhaps it was a kernel issue and the new combo has the patch baked in.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] hazmad:
Possibly, if it's a corrupt install or something. you could test it by doing just a FF wipe. you'll definitely know if it works or not. I'm just not sure if you'll keep root. you could create a flashable zip (for FF) to do the wiping for you.

I would give the options in my last post a try first though.

Try using the system.img from the latest stock U firmware. Then flash CP and CSC. This will get you calling plus which contains wifi calling and volte. However, it will also load the default sprint apps. Just use titanium to uninstall them.

I believe ever root being enables is why you boot looped, I'd just flash stock carrier firmware then restart the root process via odin, you should still be able to access download mode I assume.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] mdiaz33685:
as long as u can get into download mode, ur ok...

go into download mode, when u get into odin, just do the root process from step 1 then do step 2 again, and u will be golden again.. :D :good:

if u have no download mode, u r screwed then, and no recovery either, u would have a paper weight...

if u use odin, and something doesn't go right, u will need to reset odin, and then reboot back into download mode again for a proper flash.

Before it was maybe 4 or 5 minutes.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jokono421:
try deleting the samsung drivers. redownload them. then plug phone in while on the stuck screen. after computer registers phone unplug ,go in download mode. right click and run odin as admin and replug in phone.

i am sure u are missing something.. could be an option in odin or as simple as a missed wipe
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] kleen3r:
Are you using the system.img file from U or U1 firmware? Also the CP and CSC should be from the same firmware. I used to to get those modem crashes at first when I used the U1 system.img but with U modem.

Try using AQGL U version for part 2.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Mechcondrid:
so going to be doing this and is there a specific version of firmware i should start this on? i had pre-ordered the s8+ and (due to being a former employee of the store) was allowed to just grab the phone and start doing the activation myself so i'm still on the original pre-order device firmware version
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
well i highly doubt your radio is dead so its either ur missing something or your filesare bad.. are u flashing cp/modem files and how are you doing it and when
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
u start by reading the instructions.. the files you need are all there, you can replacestep 2 with your own updated stock system.img.ext4 if u want
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Mechcondrid:
i did read the instructions, i was more referring to if i needed to be a certain version before that. i know depending on whats done in the rooting method skipping over firmware builds or being on a later build before proceeding with the process can cause issues. and i dont know if the odin files i'm flashing are just a untouched image or something in them was modified.

just want to be sure as bricking a $850 phone not even a year in would be a severe level of suck that'd i'd like to avoid.

You posted a pic a few pages back of your system info. You are not even close to running latest firmware
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] DetoxVenom:
I did all of step 1 word for word, when I got to step 2 the only thing I changed was the system xt4 for the newer firmware by Sprint, I did not flash modem or hlos yet, and I also used the cp CSC root file provided for step 2, maybe that's why? Idk

---------- Post added at 04:46 AM ---------- Previous post was at 04:46 AM ----------

It was the latest Sprint firmware on the site provided, can you provide a link to the latest?

Shouldn't systemxt4 update the firmware code? If it does then it's not flashing it and it's stay aqde
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] eelsid:
After you complete step 2, using Odin, you should flash CSC and CP (you can try regular CSC but in order to get a good wipe you might want to use HOME_CSC) from the SAME firmware download you got the system.img.ext4 from. Don't worry about flashing modem as that is flashed as part of the CP flash in Odin.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
he needs to figure out y the system.img isnt updating first lol
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] elliwigy:
lets be clear, it does not "completely remove" green screen issues.. some including myself have still experienced some screen issues even on AQI1 firmware.... all you are doing is flashing latest combo boot.img per his guide, it is not in any way endorsed as a SamPWND "fix".. many "fixes" are not possible until we can use modified boot images or stock boot images which means an unlocked bootloader or secure boot disabled.

and as i stated multiple times, its simply updated combo firm files.. thecombo firm files used in sampwn and that are required while rooting include abl, devcfg, boot and recovery images.. so if you are updating the boot.img, its highly recommended you update all 4 of these images.. if not you will have firmware from 3 different roms and can cause issues..

if you follow guides from other threads and run across issues pleasedirect yourissues to that thread and not in here.. this isstrictly a root thread

Also, if you see a thread not created by one of us listed in OP as contributors, then it is not anything made by one of us so we cannot support or answer questions about those threads.. basically dont sendme pms about a green screen fix or a battery fix if i didnt create the thread meaning i do not support it..

i am saying this now bcuz threads are starting to pop up saying [SamPWND] in the title that we are not affiliated with at all and getting pms about them.. any official "fixes" will be added to op when they arise but so far:

1) no unlocked bl or secureboot bypass meaning no modified boot.img

2) No screen issues fix (some might have less issues updating combo firm files, this is always recommended, nothing new to be on latest possible without incrementing bootloader)

3) no battery fix (some posted but dont believe anyone actually successfully tested it meaning it didnt work. 80% is baked into the boot.img so this along with screen issues are not fixed)

4) stock boot cannot be used due to dm verity, it cannot verify the system.img when modified/rooted.. the combo boot works since it has dm verity disabled and is permissive.. the boot.img only verifies the system img.. the bootloader verifies the boot.img so this is why we cannot use a modified boot.img but can use a rooted system.img.

5) files from combo firm used include: abl.elf, devcfg, boot.img and recovery.img.. IT IS OK TO FLASH THESE USING ODIN/COMSEY ODIN

6)Besides the rooted system img and the 4 files from combo firm, everything else u flash can be from stock firmware such as persist, modem, xbl.elf, csc etc etc

I am not planning to post updated files as thatd be a huge task since newfirmwares come out all the time as well as u have the U, U1, W etc variants so beyond the sampwnd files and rooting is outside the context of this thread, u are freeto use w.esystem img or co.bo files you choose

Here is the state of my phone now.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jhofseth:
investigated/experimented with healthd -- conclusions

I

thoroughly

investigated healthd.

healthd is loaded from boot image ramdisk with hard boot.

healthd is located in /sbin.

healthd has permissions 750.

healthd can be hexedited and still work.

healthd from 7.1 Pixel XL works in our phone.

healthd from Exynos Batstock kernel works in our phone.

healthd from my latest carrier stock image works with SamPWND.

The trick to switching to an alternate healthd binary is to copy the binary with a different name to /sbin then change the name of old healthd; change the new healthd to be named healthd; and, change permissions to 750. Then open up kernel log (e.g., I used 3C System Tuner's kernel log viewer) and get the process id for healthd. Then, open Android terminal, become root and kill xxxx (i.e., xxxx is the pid you found in kernel log). Look back in kernel log and you will see healthd reloaded with a new pid. Your new version of healthd is now running.

My conclusion is that healthd is not the initial cause of our 80% battery.

I have hexedited the crap out of healthd. Shortening causes reboot. Filling with zeroes in places is OK. Zeroing security stuff does nothing. Changing 80's to 99 does nothing. Zeroing out everything except start and end ends in reboot. Every reboot ends in recovery but will boot fine after reboot.

Finally, your phone will still run with healthd renamed, then healthd process id killed and healthd cannot reload; but, the phone doesn't appear to charge without healthd running--not even at the 79% level that it would normally charge. :)
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] hazmad:
I think it's the battery and/or battery-manager service that's the problem.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
I've seen references in kmsg to offset of 20 for sm5720 (I think that's the #) which is the model of Qualcomm controller we have.

It would be awesome if healthd could be hacked to override it, but if it were that wouldn't replacing it after boot with the release version allow higher charge? Nice analysis though! One more path we can cross off the list!

I need to read the damn kernel source (better yet elliwigy should share a link to the debug kernel source) and see if I can find what got changed to make it stop at 80.

I'm still not convinced it isn't at least somewhere in /sys readable, if not writable. I haven't figured out what some of the undocumented controller bitmasks do, and after writing something to one path, accidentally losing the original value, and seeing it not go back after a reboot I'm scared to push my luck :)

Now my root is messin up like supersu crashing..
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] kleen3r:
It looks like you are still using a U1 system.img. I found that if you mismatch that with U modem you get issues. So use the U firmware instead for part 2.

Are you wiping system in part 2? Here are the steps I took for part 2.

1. Flashfire system.img from stock U AQGL firmware and supersu. You do not need to use the multi-carrier zip. Make sure wipe is listed first.

2. Flash CSC and CP from the same firmware above in Odin.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jhofseth:
Yeah, the phone was still limited to 80% with other phones' healthd binaries running. But, it is interesting that the phone will still run, but won't appear to charge if healthd is not running (i.e., not even at the 79% it would normally charge at). We have to find a way to disable 80% higher up.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] kleen3r:
Goto jkruse thread. He has the supersu.zip. You were using the U1 firmware which is a carrier unbranded firmware that doesn't contain all of the software bloat each carrier has. The U firmware contains it. But for Sprint, it also contains Calling Plus which will give you wifi calling and volte. Just use titanium to uninstall anything you don't want later.

After you're done, your about page should say 955U and everything AQGL like mine.

That's not the case for every entry in /sys. There is a huge variety of stuff controllable by sysfs/debugfs some of which lasts until reboot, some isn't writable at all, some persists beyond reboot (as I managed to accomplish). Also a fix that resets on reboot is fine as it could be set on boot.
