If lte problem persists get into hidden phone service menu and do a nv rebuild. I had to do that a few times on s7 and it always fixed lte issues

Loo I'll have to flash back to another system. Verizon's hidden menu is hidden???

I'll have to look up on that. That acts like what's up is something messed up deeper. I do lots of tweaks and switch pushing. I want to say lte has been messed up for a while but I was on Xfinity so I never used data. Absolutely 0 in one year
[Samsung Galaxy S8 Guides, News, & Discussion] zandro85:
TheMadScientist, You helped me out on the another thread and while I think what you are doing is probably way over my head I just am going to plug in a couple things anyway. I thought you could not swap Sims on CDMA phones. Maybe that was older ones that had that limitation but just mentioning it in case that's part of the problem. Other thing that might be worth mentioning is GT Galaxy Tools by idone which supposedly will allow you to show Hidden menus on Verizon as well as having a whole bunch of other features. I used it a lot on older Samsungs and it helped tweak things in many ways. Not sure where it might be available anymore but if you want to try it (or don't have it) I'll upload it somewhere in a few minutes and will update with a link if I can (not sure if I can post links yet so if not PM me).

I uploaded it here: http://s000.tinyupload.com/index.php?file_id=09580243835570346049

There are two versions in that zip file. I have a note in the title of one of them to "DON'T USE" and while it shows clean at virustotal.com I forget why I put that note on it but it's probably safe to try if the other version (smaller one) doesn't work - it might have just failed on one of my phones. The smaller one always worked fine on anything I tried it on.

I'm fairly sure those two versions I uploaded are the older free versions but I see there is discussion here and apparently links to some newer versions in case you want to look into it further: https://xdaforums.com/note-4-sprint/help/galaxy-tools-download-link-t3040971

Phone Info + has secret codes that can get you into the hidden menu usually but I think just entering this into your phone dialer will get you the hidden service menu: *#197328640# and I think this works on the S8 / S8+

Or not - not working on a VZ model I've got but I'm guessing one of the secret codes you can get from Phone Info + by Vndnguyen may work.

---------- Post added at 07:03 AM ---------- Previous post was at 06:52 AM ----------

Just found in Phone Info + under "Other Tools" in the menu you will see "service mode root" and "service mode no root" and that gets you the service menu that has all sorts of options. At least on my rooted Verizon phone it gets you there (and can get you into all sorts of trouble if you aren't careful with changing things).

Question

My s8 update to android 9, v5 bootloader.

How can i root my phone?. (how down to android 7 to root?, plz help). thank
[Samsung Galaxy S8 Guides, News, & Discussion] Superguy:
Follow the method in the OP and you'll need a Nougat rom, such as Dream Rom or jrkruse's linked in the OP.
[Samsung Galaxy S8 Guides, News, & Discussion] hoanggo:
Thanks . i done step 6.

7. You will also have rooted combo firmware installed?? (what is "combo" firmware meaning?)

"Read step 8 of the OP's directions. This is not a usable rom. You need to flash a compatible system.img to your device. "==>i find a system.img in G950U_V5_9008 folder. what is it? Rom?, how can i use it?)

After days of work i finally figured it out. I did all my work in the combination files. Had a NV issue had to rebuild. Thank you for the response though wish i woulda seen it. Woulda helped ???

At the time i wasn't rooted so none of them worked for me. I ended up doing most of my repairs with DFS CDMA tool. Had broken NV settings i had to fix.

I couldn't really run root at the time for some reason. If the app didn't come preinstalled. It didn't work. Any of them. All apps where force closing

But with loads of work im up and running my stock rooted on bit 5. On verizon. With WiFi calling volte and LTE. Now we need to fix Verizon vvm???

[Samsung Galaxy S8 Guides, News, & Discussion] Superguy:
I get occasional crashes (black screen of death) and it cites the modem as the cause. Has anyone had this, or did I do something wrong?

I'm using an AT&T based 950U and did the process here. Have BL v5. I tried several of the roms here (955U based), Dream Rom, and now PartCyborg's ROM. It's crashed on every ROM.

Does anyone know how to fix it?

It's not a huge deal - mostly a minor inconvenience so if I have to live with it, I can.

Thanks!
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Happens in all of them. We've had this issue since root day 1 just about. I think it's a issue in the bootloader images. Only one it rarely happens on for me is a full stock system img that i built up myself. But even on mine. Couple times a week

Is there any OTA friendly U1 firmware, that I can run alongside safestrap? (v5 sm-g950u)

Or, a way for me to use an extracted system.img, and actually get it to work?

I tried various from CRF5 to DSC1, but couldn't get system.img to work. So, I'm either missing something, or it's not possible. I just really miss so many disabled features from U1 Pie beta, such as spam blocking, antivirus, etc.

[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
You can work fresh data wipes. When i first did this i had all kinds of issues. A factory reset took care of most of it
[Samsung Galaxy S8 Guides, News, & Discussion] Sleepsy:
Thanks for the tips. It's usually a missing small step that manages to drive me nuts w/ devices.

Maybe half my attempts were wipes, especially since my main safestrap backup managed to corrupt itself. I would wipe data [and cache again], mainly after a failed boot, as I was willing to attempt anything to salvage the attempt. Especially, since it wouldn't even load safestrap in many of the cases (after flashing back to safestap eng bootloader w/ odin)

I was reading in certain situations, that mounting system/etc., could make a difference for specific types of install success [even if mount errors during install.] That being said, they weren't exactly my situation.

On a side note, did you have any luck with simply flashing the BL in odin, or do you think flashing boot.img would be any better? I was assuming it was pointless, since I always just flashed BL's in odin to swap from safestrap to OS.
[Samsung Galaxy S8 Guides, News, & Discussion] dd805bb:
I us d the one in the Verizon forum. Worked great. Took a few tries. Also I only use that system from the folder and install in safestrap. Their is a zip that is recommended for safestrap to flash. I used that and an adaway zip. Both worked. DSC1 and I got pie official. It is ota friendly. Or so it says. Haven't had an update yet, so can't say of it works or not. But everything else does. U1 and dark mode. Had an issue with finger print at first, but it updated some apps, and works great now. I had it in a drawer for months because I crashed it months ago. Just fixed it using this and that ROM I mentioned. Now got another back up phone.

[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
On this 1 yes and 2 you can do either and or flash in safe strap

On the 80% Man let me tell you once your up and running specially Cyborgs rom the battery life is fenominal And its perfect if you charge over 20% My battery over 1 year old has 2 recorded full battery cycles I have only charged my battery to full like 3 or 4 times and it holds up better than most around the same age

20% and 80% are pristine charging percentages for maintaining a healthy battery as long as possible At current I can easily IMO get another year of use on this battery

[Samsung Galaxy S8 Guides, News, & Discussion] Sleepsy:
Thanks, I'll keep trying. No clue what detail I'm missing/messing up. I'll try the one from the VZW forum, vs the one from sammobile & samfirm.exe downloads. I doubt it's any different, but I'm about to search for the thread.

Out of curiosity, after flashing the U1 DSC1 system.img file in safestrap, and subsequent DSC1 BL, did you do the [relatively] new 2 file SafeStrap enter/exit? Or did you use the older PITA method, with 8+ steps and ~5 BL files?

Over the weekend I had somewhat started from scratch, as my only full SafeStrap backup got corrupted. [included personal files, apps, etc.]. Luckily I did a samsung backup + manually copied files. Just a pain to drag icons to the desktop/customize most of the settings I ended up losing wifi hotspot with DSD3, even with installing the zip files. So, I needed to reflash anyway.

Safestrap Boot Option Disappears

Hey, I used this method about a month ago to root my S8 once again and bring it back to Nougat.

After a while of usage and system app removing, I removed an important apk and broke the system. When looking to go back into safestrap, I no longer get the option. Booting with the recovery button combination also just brings me to the default recovery options.

Is this a problem or is it supposed to happen after ROM installs? Planning to re-do the process anyway though

[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Yes once you have a system image with safestrap you just from that point on flash any modified system image with safestrap be it an Oreo or Pie or nougat system image. If you use the sfuff from my s8+ Verizon thread and follow those directions to enter and exit safestrap you can bounce back and forth as you like.If you are still v2 bootloader you can just root install safestrap you don’t even need too do this unless you jump to v5 bootloader and somehow loose safestrap or root this will get it back. The guy that gave me the edl files only gave me partial edl files so I don’t have the files to fix a hard brick with say sbl error or dead device fix

Issue with installing

First off, thanks to jrkruse and everyone who got this working! This will be great once I can get this working, but I've run into an odd issue with installation that I haven't seen in this thread. Hopefully someone can help me, as it's worth quite a bit to get it working. I'm really new to Android stuff like this, so hopefully the answer is obvious to someone.

I made it through the first four steps without any issues, but when I got to the fifth step where you have to install the BL Safestrap md5, I got a validation error in Odin where the checksum wasn't valid, and then the phone froze up. I panicked and reset the phone, and when it reset, I got rebooted to the "Safestrap disabled" screen where I could get into TWRP from there.

What is missing due to step 5 not being installed? Is there another way to get that installed now that I appear to have full access to TWRP? Does it matter that it wasn't installed, as it appears to me that I have Safestrap (although I don't know how to use it)?

I really want to get this right so that it doesn't cause a ton of issues down the line.

Are you using stock odin or modded odin? There is a v3.13.1 patched odin on xda just google it that might solve your problem or PrinceComsy odin v3.12.

Thanks, I got it fixed now! For that piece, I was using stock 3.13.3 Odin. I don't remember exactly why I switched midway though, but I was doing way too much research and must've gotten scrambled a bit. I didn't know that different Odin versions would make such a difference.
