HELP! "Your phone is locked because the payment service was uninstalled." - Samsung Galaxy S10 Questions & Answers

I got this issue while rooting my SM-G9750 s10+ with an unlocked bootloader. Did anyone else with root get this during the root process, and what caused it? This happened after a factory reset.

I had this but it happened after debloating system apps, including this one. Only solution for me was to re flash stock, then patch and root again.

Let me know if you figure out a workaround. Its related to KNOX debloat.

Flashing stock with Odin including factory reset can be helpful but this Knox protection can cause a full brick. It's possible that you need to send the phone to Samsung and eventually pay for a restore.

This happened when I debloated samsung pay by freezing those apps. I flashed a zip in recovery to enable all frozen apps and then installed google pay, then I could then debloat those apps without issue.

If you have a PC with ADB & admin -you should be able to reinstall the package via a command prompt. I was testing out removing various packages, uninstalled this and got immediate phone lock but reinstalling it fixed it immediately. I used this:
Code:
pm install-existing --user 0 com.samsung.android.kgclient
but you may need
Code:
pm enable --user 0 com.samsung.android.kgclient
or similar if you disabled it rather than uninstalled it. I don't use disable so not sure I've got the syntax correct.
Otherwise as others have said a factory reset should fix it.

Ya knox guard seems to mess these phones up its disabled or removed. There should be another application that looks for its status that we could modify/remove.

Someone's figured it out because I've used a pie ROM for the S7 with no payment services (kgclient) installed. Black Diamond NFE i think.
If you pluck it out before installing a ROM it'll still freeze the phone on the ones i've made myself. Not sure where to look but have spent plenty of time doing so.

Just to help out anyone stumbling across this on their new phone:
If (in ADB shell) you disable packages via
Code:
pm disable-user --user 0 PACKAGE
Then you can re-activate them via
Code:
pm enable PACKAGE
My phone just showed the locked-screen and did not want to interact with me anymore - well, besides ADB that is.
I re-enabled all packages and found my phone still locked.
A reboot solved that, leading me to believe that whatever breaks down when disabling it, will not get restarted on its own.
So don't panic, but re-enable all packages (feel free to run "pm list packages -d" to make sure) and restart.
My phone did come back in ADB - so I assume that even the locked phone will come back up but you might want to always trust you device's fingerprint

id be surprised if someome figures out how to block kgclient lol.. woukd solve a lot of problems for ppl

I believe it's been done pretty much a year ago. No sign of knoxguard a.k.a. kgclient here:
https://forum.xda-developers.com/s7-edge/development/blackdiamondfesmooth-fastv1-0-t3915483
(Great ROM by the way).
*When i did debloat builds for the A8 i could not flash a zip without it. There's (obviously) something that is enforcing its permissions when uninstalled or not included in a 'new' OS install. I tried commenting it out from certain files with (again, obviously) no success.

I'm trying to rember...On my Note FE it happened when I debloated also. I can't remember if it was Pie or Oreo. But on one those versions it was ok to remove. Also same issue using Titanium Backup. Oreo you could but on Pie you couldn't update apps. But I haven't touched my FE in ages

yea.. kg client is baked in good.. in dl mode u can even see kg status.. if its prenormal u can only flash stock official binaries even

Pie
I first had the issue in Pie on my A8. If i'm not mistaken it was the introduction of the name knoxguard for the folder that contains the kgclient demon.
The NFE port i spoke of in my last post has many files with its filthy name all over it just like (presumably) all Samsung phones have from 9 onward.
There is some good work on that ROM and if it can reveal a solution... i wouldn't say. I feel guilty just tryin'.

just looked at that rom link.. its an old s7 device, unlocked bl, custom kernel etc etc..
i dont even think kg was a thing at that time at all lol.. so its quite different..

It was for me beginning on July 29, 2019. The S7 ROM was Pie as was my A8 when my screenshot is dated from.
It's been since Pie that its removal caused the.... screenshot. Not all that long. Since 9.0 which will vary by device/discovery.

my question is why r u posting about s7 or a8 in a s10 thread?

I was posting about having kgclient removed from one ui pie, which last i checked is the same OS on the S10.
Well, now Android 10. Anyway if you don't understand the point i cannot explain any further.

u cant remove kgclient.. at least not without root or unlocked bl and even then it wont go easy..
my point was that u will prolly have better luck in ur device thread than traversing into other random threads and posting about different devices.. it causes confusion believe it or not with a lot of users.

No.
---------- Post added at 02:38 AM ---------- Previous post was at 02:30 AM ----------
Kgclient is not unique to the S10. It's a Samsung thing starting with Pie and continuing into Android 10. If it is eliminated on the S10 or any other device then it should be the same fix. I stand by my post.
---------- Post added at 02:44 AM ---------- Previous post was at 02:38 AM ----------
I was pointing out that it can be eliminated (as far as i know only by root) by giving an example of an OS used by the S10 where this has been achieved. This means the same solution should (likely) exist for the S10. Confused?

[Q] Ping Pong Anyone?

I do not have an S5, but may well get one in July. I expect it to come with Lollipop.
Any idea if this
http://forum.xda-developers.com/galaxy-s6/general/root-pingpongroot-s6-root-tool-t3103016
will work on a new S5? Sounds as if someone may need to submit the new ROM version to be included.
Thanks all.
If it mentions its specific to S6 and has no mention of your device in the devices section..then I wouldn't dare try it unless the creator says its okay...I mean you could always just go for it but that's probably not a good idea unless you don't mind risking your device.
Yes, I know that. I am hoping someone with the latest stock ROM will submit it with the hopes it can be supported.
tried and failed
Tried it with my T-Mobile s5 running the latest version of touchwiz and it just told me "did you install SuperSU before root" or something along the lines of that. End of point it didn't work... Don't understand why though... Both running basically the same touchwiz so the exploit should be the same
I have a thread on rooting news fo the S5 Lollipop update, if you want to post something of this Theme please post there.
Getting into your question in the thread i mention a guy already try it and failed.
I have tryed to root my galaxy S5 too and pops up the same error ´´Have you installed SuperSU before root?´´ I guess it´s because of the Knox security in this case 2 . 3 of Knox version that rolls back the SuperSU intallation after its process... we will have to wait a bit more untill developers come out with something that can bypass Knox security for Android 5 . 0

Getting rid of Sprint/LG Bloatware

Does anyone have a list or a link to a list that we can refer to for removing/cleaning bloatware that comes with stock Sprint LG G4?
I've tried bloatware tool but that doesn't remove anything, it simply hides it so its not visible.
Thanks!

Seconded, we should have a community list of apps that are safe to remove from the Sprint version of the G4 without breaking anything vital, now that we have root. OP if you haven't, I'd suggest you go and root your sprint G4.

Debloating tool is obsolete if you have root because you can directly freeze or even uninstall unwanted apps with root apps like Titanium Backup. There was a list floating around somewhere of apps to use the debloating tool on, but now that we have root I'd rather see someone compile a list of apps or apks safe to completely uninstall.

@elsamuraiguapo quick question. I have Titanium used it on my Nexus 5 and I suppose I got spoiled not having bloatware. I'm kind of fuzzy on the freeze option in Titanium since I've never needed it. What does it do? I know you can uninstall apps with it even though I never needed to.
Waiting till tomorrow to root this phone! I can't live without root!

I would personally hold off on rooting the device until we have a KDZ/TOT file to return to stock in case of a soft brick. I have personally bricked 2 devices now trying to freeze/uninstall via titanium backup.

Is this post what your are talking about?
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
I've been spoiled so far having a Nexus devices. Had Wug Fresh's Nexus Root Toolkit. Everything was a breeze. So if you'd be as so kind to tell me what KDZ/TOT is. I've see that acronym quite a bit the past couple of days.
Using Titanium I would more likely freeze rather than remove. I don't see how that could soft brick the phone. Mind you I'm no expert so try to understand my ignorance in the matter.
So is this just a matter of the phone being really new and if I just sit on it for a few more months rooting and recover may change?
I just saw that URL you left about the Debloater. I'll have to check that out.

Yes that's the post about KDZ, and Basically KDZ/TOT lets you re-flash your phone back to stock like you just bought the phone from the store.
And evening freezing them may cause an issue, not 100% sure haven't been able to play with it much lol. Because yes the phone is so new, not a lot of development going on.

N9650U/W stock rom Question..please help.

Hello,
I was wondering if anyone could help answer my question about tweaking a stock rom, hopefully that should remain flashable with Odin.
I have a Canadian variant, I know they're essentially N9650U devices with the beloved lockeddown bootloader..
Since discovering Adhell, I've accepted Knox and Sammy firmware without root.
I wish to upgrade to OneUI firmware. but, would rather remove the packages from the Odin ZIP, rather than disable or uninstall via adb.
My question is this:
Is this still possible?
I've seen minor tweaks to a stock rom on the S8, certain packages removed from the rom, a few others added, nothing requiring root of course. But this was fantastic in maintaining more control over my device.
its tedious and time consuming to have to disable or uninstall the selected packages more than once or twice.
i was planning on doing a clean install with a few less packs, like Samsung pay, or the bloat..
I'm certain this has been asked before, but I couldn't find anything. please forgive me if it has.
Thanks for the help.

Good question. I am not sure if removing those packages would "modify" system. I'm assuming it would as the size would be smaller, but I'm not sure.
All those apps can be hidden without any "tweaks"

Bought used. Security concerns?

I had been looking for a new phone for awhile. Settled on a Note 9 because I wanted to try using the S Pen for work and dislike the Note 10 design. However, they are still sold at full price where I live, so I bought one secondhand. Everything seems generally fine with it, minus some freezing or weird reactions when it charges for awhile or restarts. But I have been skeptical of throwing passwords (personal and for work) on it to this point. Thats because I read an article about potential root level or firmware level spyware that remains after a reset.
I did a reset AND even took it to an official service center to flash new firmware (but they said they cannot do it there, but they did some kind of more advanced reset?). I checked my Knox counter in the Download menu and it reads 0x00000, maybe more or less zeros. Samsung pass, pay, health, and secure folder all seem to work (I can register for them, use the bio sensor). That all sounds like it has not been tampered with in any way, correct?
Thanks for the help.

If you are worried about remaining spyware of files, download the latest rom from sammobile and then flash with odin.
Just simply search how to use sammobile or how to use odin if you need help. Hundreds of years have posted how good and answered those questions already
I used to flip phones up until a couple years ago. I've bought and sold hundreds, maybe thousands of used phones, most of which had my accounts on them at one point and time. I think as long as the phone is running official firmware, isn't bootloader unlocked/rooted, and you've reset it, it should be fine. Of course you run the risk that someone has hacked it, installed spyware at the system level, and somehow overwritten the status to show as official such that the spyware persists even after a reset, but that's highly unlikely.

Thanks for the idea. I considered this but would like to avoid just because sammobile is unofficial, so it would still leave me slightly apprehensive even if everyone is using it.
Everything I read seems to suggest that the phone was never rooted if all of the Samsung apps work and the Download KNOX counter is 0x0. Just wanting to confirm by someone more knowledgeable about this.

Go to settings > about phone > status and it should say "official". That would tell you if the phones operating system has been modified (rooted). As far as checking for bootloader unlock, I'm not sure on Samsung's but on a Google Pixel once the bootloader is unlocked it'll show an unlocked lock on the bootscreen every time that you reboot the phone. North American snapdragon variants of Note 9's do not have an unlockable bootloader so if your phone is a carrier branded phone, the bootloader can't be unlocked. You can Google your model # to figure out which one you have.
You can also check that all functions work properly. Typically apps like Samsung Pay won't work if the phone is rooted. There are ways around that where you can trick the phone into thinking it's not rooted to get those apps to work so, again, that's not a full proof way to check. For example, I'm using an AT&T variant that's been sim unlocked and flashed with Verizon firmware and it works 100% like a Verizon phone.
I'd say, reboot the phone. If you don't see an unlocked icon it's probably not unlocked. Go into settings and take note of your model #
Then go online and research about Odin and flashing official firmware via your computer. Download the latest official firmware for your phone, flash it using Odin, and then you'll know that there's no spyware on your phone. That would essentially be the equivalent of wiping a computer and reinstalling Windows.

yeah.. i whouldint fall for that system/status official crap. as you can see in the screenshot i posted from my rooted n960n.
the only real way is to check if knox is tripped is in DL mode( turn phone off. hold bixby and vol down button while inserting a usb cable hooked to a computer.).
also flashing a stock firmware on an FRP locked phone wont do **** if someone has had their accounts logged in/registered on it and have not reset it correctly.
surprised you dont know this.

FYI - This phone does have an unlockable bootloader.
I'd recommend using Bobby's advice and flash the latest firmware with Odin. If the phone is not already on the latest update, you could flash one firmware less than current and then let the phone download and install an OTA to the current version. You'll know that its official if the phone successfully downloads and installs the OTA.

Not sure why you're trying to call me out when I clearly said there are ways for it show official if it's rooted. Also, no one said anything about FRP. If the phone was FRP locked they wouldn't be able to use it at all... Unless you know how to remove an FRP lock, which I do. At that point the phone would work/be a normal phone.

point taken on the FRP lock but the real point I was making is that the system status is bogus:

You obviously didn't read the entire comment:
"There are ways around that where you can trick the phone into thinking it's not rooted to get those apps to work so, again, that's not a full proof way to check."
Or this comment:
" I used to flip phones up until a couple years ago. I've bought and sold hundreds, maybe thousands of used phones, most of which had my accounts on them at one point and time. I think as long as the phone is running official firmware, isn't bootloader unlocked/rooted, and you've reset it, it should be fine.

There are a lot of ways to check. I pointed out some of the simpler ways. None of which are truly bullet proof. Hell, back in the day we could reset knox counters so if someone is going to the extreme to install some spyware and they're smart enough to install anything that would persist a factory reset, even checking knox isn't a full proof method.
And your screenshot really doesn't tell me anything. It's possible to have an unlocked bootloader AND official firmware at the same time. The operating system and bootloader are two different things. It's only when you modify the system that you have to hack the status to make it say official.

There are a lot of ways to check. I pointed out some of the simpler ways. None of which are truly bullet proof. Hell, back in the day we could reset knox counters so if someone is going to the extreme to install some spyware and they're smart enough to install anything that would persist a factory reset, even checking knox isn't a full proof method.

fine but i mean, why ask a user to validate the state of their device via the worst possible method of them all?
he even already posted in OP that he went to DL mode to check the knox fuse status so would supersede by far the need to check via software/status.
edit
and the photo of my device status was just a way to show how i know device actual status and bootlaoder state aren't linked. especialy when rooted devices can spoof software status but none cane spoof fuse state in DL mode. so not sure why you are trying to convince me of something i just proved. u can say u agree next time.

No actually he didn't. He never said he went to DL mode, he just said the knox counter says 0x0. That can be checked via apps from the phone. If the phone was rooted, it could be manipulated to show 0x0 when it's really not.
You're focusing on one sentence dude. Get your panties out of a wod and read the whole comment.

Sorry for the confusion. I was referring to the Download mode by hitting the mentioned buttons on restart. The KNOX reads 0x0000. Also, it says OEM Lock: On. Then you are both saying the phone is safe?
Also, when I first got it, it did find an update OTA and installed it.

no confusion on my part. i read and understood you correctly the 1st time around.
at first glance your device looks ok but...
additionally, there are ways to check if the device is off a lease with a ESN check. meaning if someone sold you a device still on contract. some sell contractual phones and after a period of time they will get blacklisted since the contract is never payed off fully. so device would appear to work fine and one day they just stop getting a signal and esn/imei get blacklisted.
side note:
surprised that this was not brought up earlier in the conversation as a factor to watch out for by some "experianced in the field flipping devices" user instead of stating the obvious like device status and the unreliable means to check it. especialy since, said user stated buying and selling hundred and even thousands of phones...!? ESN state would be no. 1 in the check list if things to watch out for.
anyways back to the current case, there are ESN/IMEI check services in the web to see status of device: stolen, still on contract...etc. i cannot provide any suggestion to these services unfortunately. this is something you need to check yourself or ask around.
good luck

I had been looking for a new phone for awhile. Settled on a Note 9 because I wanted to try using the S Pen for work and dislike the Note 10 design. However, they are still sold at full price where I live, so I bought one secondhand. Everything seems generally fine with it, minus some freezing or weird reactions when it charges for awhile or restarts. But I have been skeptical of throwing passwords (personal and for work) on it to this point. Thats because I read an article about potential root level or firmware level spyware that remains after a reset.
I did a reset AND even took it to an official service center to flash new firmware (but they said they cannot do it there, but they did some kind of more advanced reset?). I checked my Knox counter in the Download menu and it reads 0x00000, maybe more or less zeros. Samsung pass, pay, health, and secure folder all seem to work (I can register for them, use the bio sensor). That all sounds like it has not been tampered with in any way, correct?
Thanks for the help.

Reading this thread I've come to the conclusion that you should sell your rootable and boot unlockable device and buy a locked down USA model.
Thank me later. Least you'll be able to sleep well now.

It's about as safe, in terms of spyware, as you'll ever get from a used phone. I would assume you checked the ESN before buying it but if not, run a check with swappa.com/esn and checkesnfree.com to make sure it's clean. Screenshot the results and save them. Depending on your carrier you can likely run a check on their website and/or call support and ask them as well. As with any unlocked phone, know that you may not get all of the features that a carrier branded phone would have (i.e. I couldn't get WiFi calling working on a Korean S10 on Verizon).

Samsung Galaxy S20 FE 5G ROOT

Is the Samsung Galaxy S20 FE 5G rootable?
yes it is, there are 2 or 3 threads where people go over the methods they followed
Just don't update it past rev 1 or 2. 1 to be safe.

Unfortunately that is for exynos. Not sure how many people need to know how to systemlessly root an exynos. Full root might be more useful for exynos users but good ol' snapdragon has everyone in a pickle (most everyone.)

there's zero difference in how both models are rooted. systemless root has been the standard method for all androids for a long time now.

Yeah almost every phone is rootable but it will either cost money or if you've updated your firmware then you'll have to wait until they figure out how to get past it, assuming they do, they always have just takes time. If you have updated your firmware you can look in to selling your device and buying one that hasn't been updated. I can give you more pointers on how to find phones that haven't been updated for cheap but that's only if your interested and no I'm not selling anything.

Oh really. So then why does snapdragon lock the bootloader while exynos doesn't? Not to mention a root that works on exynos won't necessarily work on snapdragon. I thought this was fairly well known.
What exactly are you referring to by model?

magisk doesn't have different versions for different devices and it's been the standard root method for a few years now. since version 22 how it works has changed for all new phones.
I'm on a snapdragon that didn't have a locked bootloader because that's only done in the US market (at the request of or to please US carriers I'm guessing). SM-G780 is a model number of the Exynos S20FE... SM-G781 is the Qualcomm, they both use the exact same method to obtain root.

I didn't see your other post. I'm not really in to getting in to these debates online not really my thing but I still use full root myself and systemless as well. They both have their pros and cons. I suppose I prefer to edit system files myself to overclock the device instead of depending on an app to do it for me.
There are lots of people still using full root. I think a long time in terms of electronics can be hard to pinpoint. I've used full root way more times than I've used systemless but I guess that's just because I've been doing it for a long time. I know some linux phones you can buy don't come with systemless root but only come with full root and they don't make systemless root phones off the shelf like they do full root for a reason. To each their own.
google and OEMs have made messing around with the system partition harder, it's read only now and overlays are how edits are mostly done. plus there are more apps that won't run if root is detected, systemless gives you the chance to evade that detection if you want it.
CF-autoroot is pretty much dead, the superSU app is owned by a private company and Chainfire had moved on.

Oh thanks for the info. Yeah I've definitely used systemless. I did like it but of course there's nothing like doing it yourself. Although I rooted phones back in the day I've also used Magisk though I could've swore I was able to use vi and edit system files that would've been unreadable and definitely unwritable but I'm pretty sure I just changed the mount of whatever it was I was working on from ro to rw with 'mount -o remount,rw /' I'm to lazy to pull up Magisk I think I have it on a tablet somewhere. I probably also changed the file permissions with chmod or chown then chmod but I think there are some files you can't change using systemless now that I think about it hence the name systemless I dunno it's been awhile since I messed around with rooted phones.
After awhile you realize how vulnerable the device is after root and then when you think you can trust these apps that have root access then someone announces they found "_______" app pulling user information... I'm definitely not referring to any apps used anymore but it was the app people used before they used Magisk and it pretty much did the same thing but I wouldn't be surprised if newer root apps did the same.
Wait you said since SDK 22? Was systemless even around then? I don't think it was. I know it's been around for awhile but not that long.
I did find out something pretty funny when this guy was rooting people's phones and he had a contact in China... I was determined to find out who this Chinaman was. Well I don't think I should really say out of respect because he clearly didn't want people to know where he was from but yeah I guess I'll have to keep that to myself but it was pretty funny to say the least.
Also this was before rona so him being from wherever was irrelevant I just wanted to get it cheaper than what everyone else was paying. Turned out to be some old guy and unsurprisingly as you've assumed, not from China, or was he? He actually just unlocks phones and didn't acknowledge I even used the word root, he was thinking "oh no, they've found me."
@Flucker08 I meant since version22 of magisk not SDK22.
rooting with magisk used to be something you could do all from a custom recovery. now you have to download your firmware and patch it with magisk on your phone and then flash the patched image from PC
Hello
Please tell me, if i rooted Samsung s20 FE 5G ( Snapdragon ) can update new Firmware its Odin ? and not lost my all user data ? ( i hope to not must clear ) and rooted again ?
Please write, how to do it ?
after the first time rooting and unlocking the bootloader (so you could root) you wouldn't have to wipe again.
you would download the updated firmware, patch the AP file from your phone same as before and flash the downloaded firmware and patched AP all together in Odin @onken
if you select CSC_home for the CSC partition your user data will not be wiped !!
Hi
Ok, thanks for info @3mel
Please tell me yet, patch the AP i must prepare before flash new update firmware ?

yes, you download the update from somewhere. extract the AP file from the archive and copy to the phone. run magisk from the phone and wait till it's finished. copy the patched file back to your computer and use it along with the rest of the firmware files. again for CSC you MUST use the HOME_CSC file and not the regular CSC if you don't want the phone wiped.
that last part only applies when updating the phone, the first time you root you will have to wipe.

It is advised against updating after root. If you're on exynos I don't know but snapdragon it will make you lose root and no getting it back. It's said you can do it by removing the boot files from the firmware before flashing but I haven't tried just heard about it. Honestly you should just leave it. You aren't missing out on any amazing features. Most updates are security and if you're root you don't have much anyways.
All ok thanks for advice

Hi @3mel
If I unlock, install twrp and root with magisk as per afaneh92's method, since I have twrp now, how much will the update method differ from what you mentioned here, if i don't want a wipe. If possible, can you please tell the steps in brief or provide a source? Sorry if this is not the right place for asking this.
I'm on SM-G781B/DS with OneUI 4.1(Android12).
