How to uninstall
This is by no means an extensive guide for unrooting, but if you want to sell or warranty your device, I advise the following procedure:
- Use Triangle Away to reset the flash counters, and pull the battery immediately after rebooting starts
- Boot into recovery and perform a wipe, and pull the battery immediately after rebooting starts
- Go to SamMobile and get the stock firmware for your region
- Flash that stock firmware on your device
- Let Android boot, go through device setup (without doing any logins) until Android is fully usable again
- Reboot
- Wait at least 10 minutes
- Check Settings->About device->Status and make sure Device status is not "Modified"
- Perform another factory reset
- Boot into download mode and make sure the flash counter and system status are all set to official
Some of these steps may require further info, if you can't figure it out, do some more searching, or ask people who aren't me

[Q] Flash counter warrenty

Hey there
Will using TriangleAway to reset the counter and flashing to stock with ODIN definitely mean that service people will not be able to tell the phone has been modified at all?

Its possible there's a hidden counter but what we can't see we can't guard about...
I would also suggest to hard reset(factory reset in options) completely to reset all statuses..

Also because the s4 does not show a triangle on the download mode screen, Is there any way to check the counter without using triangleaway? and how do they check it in service

If you simply boot in to "Download mode" the phone will show if you have an official or custom binary.... there is no counter...just says custom or official. ..so just do a firmware flash via odin and then a hard reset (optional) ... then check your binary via download mode...I'm sure it'll be reset to official
Good luck hope this helped

Imgoing to test it
Thanks Bro....
:good::good::good::good:

Also in settings go to About>Status and at the bottom it will show either "Official" or "Custom"... This is the bugger that's hard to change...

Im pretty sure there is a counter, It shows up in the triangleaway app

You have to do it this way.
1. Make sure you have a stock Samsung kernel and recovery (triangle away needs it to work on the s4).
- It may be easiest to flash stock firmware and then root again.
2. Once you have stock kernel and recovery and are rooted you can run triangle away. Make sure you follow the instructions carefully as it's a different procedure from older devices.
3. Flash stock firmware that your phone came with. I've discovered the hard way that Samsung service centres match the serial number to the firmware version as another means of checking for software modification.
4. Factory reset.
If you've done everything correctly you'll have official binary/status normal in download mode.
I've done this procedure myself and can confirm it's 100% working.

[Q] galaxy s4 gti9505 WAS rooted but cant change status back to normal

hi all, as you can tell, im a noob well, I have a samsung galaxy s4 gti9505 that I rooted with odin WHEN I had a pc, and it just so happens, whenever I root an android, it works but then things start to go wrong like lagging, freezing, drainage of the battery really fast ect. So this time I decided to google how to unroot my phone without a pc to fix my problem. I did that using super su or something which had the unroot option witch I did successfully. But just a few moments ago, I was just checking to see if there were any updates available for my phone because my camera decided to stop working, (well the camera works but when trying to record, a pop-up box appears saying camera failed). So when I tried to update, it said that I cant update because my phone is modified, now as stated above, I am a noob to this subject so please be patient with me trying to comprehend the technical terms use will use hahaha. Can someone please explain to me if it is possible to change the status from custom to normal without the help of a computer? Thanks in advance

help meeh please
Can anyone help?

I don't understand why you want to return back to stock without computer/laptop. In any case following instruction will help you to return your S4 back to stock:
1.First you need to download official firmware for your region from this site: http://www.sammobile.com/firmwares/1/
2. Second upload it to phone with Odin http://www.andromint.com/download-odin-latest-version/
If needed you can also use Triangle away to reset custom flash count.
That's all...

Dear all,
I have a similar question.
I've rooted my i9500. I wonder is there any way to roll back my phone like Triangel Away etc. I mean in case of any guarantee situation.

As far as understand, as of now no way to reset.
I hope someone can find a way to reset everyhing to get warranty back.

You don't need to un-root before flash ... you will for sure lose root anyway

Is there any way i can download at more than 200KB's?
http://puu.sh/4YTbL.png
Cause the captcha for the rom download on the link says it's wrong even when i type it right..

I must do something wrong here, because it's not working for me.
I followed the instructions and device still says it is modified and it will not check for updates from samsung.
What is my next step?
Procedure so far:
Gained root acces with ODIN
I did not flash a custom rom.
Used Triangle away to reset counter (counter checked 0 afterwards)
Flashed Galaxy stock firmware downloaded from internet (PHN-I9505XXUDMHB-20130922121848.zip unpacked this once) with ODIN
Furthermore, regarding KNOX reading:
KNOX KERNEL LOCK: 0X0
KNOX WARRANTY VOID: 0X1
(I suppose the latter means Samsung still is able to see I did something)
Would a hard reset solve this issue do you think?

Need help on unfamiliar error screen. Image provided.

Just got the Note3 from a online seller who seems to be legit but when the phone was received via the mail, it didn't work as expected.
I've had some experience with android ROMs and rooting but those are mostly for the other phones, this is the first Samsung phone i got. Could you guys help and advise what to do to resolve this error?
I've actually downloaded Kies3 and use the emergency recover thing, but most of the times it couldn't detect the phone connection.
And on the rare occasion that it does detect something, it says that the model is incompatible with Kies3. Tried it with the old Kies too, but didn't work as well!
UPDATE <21_03_2015><16_54_09_524>____________________________________________________________
I just tried flashing lollipop from http://forum.xda-developers.com/galaxy-note-3/general/finally-official-5-0-firmware-galaxy-t3029557

first_boot_after_first_flash
Second_flash_no_pit
3rd_flash_with_pit

I think that this error appears when a ROM isn't flashed properly to the device. So a possible solution might be a factory reset in recovery and a clean ROM flash with Odin. You just need to download a ROM for your device model - SM-N9005 from sammobile or samsung-updates.

Is Odin a entirely different piece of software to kies?
Also would you this to be soft brick and reason to demand for compensation from the seller?

I wouldn't take this advice as you bought a phone that is soft bricked with knox tripped (0x1)
try and return it before you attempt to fix it.

It looks like your knox is 0x1 and the system status is 'custom' but i can't really tell as the quality of the pictures isn't good enough.
This means that the phone has been used before and rooted, then a wrong flash or simply just deleting a few system files so it doesn't boot to get that screen to show up instead.
If there is nothing wrong with the hardware, Odin should fix this easily.. but i wouldn't trust it as your imei could of been changed.. many things could of been tampered with.
Also you mention that kies doesn't detect the phone properly, only sometimes. This could be your pc but it is likely a hardware problem with the phone judging by how you recieved it with knox tripped (0x1).
As it has been sold in this condition i can only assume that it has been tampered with. Why else would the seller sell a soft bricked device ?
Was it advertised as new or used?
Return it and get your money back as soon as possible is all i can suggest, good luck.

1. If its possible for him to return to the seller then yes but he can't to samsung. Due to knox being tripped. If he does its just basically a 50/50 chance
2. This nothing to do with soft brick. Such thing as a soft brick doesn't really exist.
3. Using odin to flash any official firmware. Is not bad advice.

The seller is not responding to my questions, so I think the next best bet to attempt and fix it myself. Am I right to think that flashing an official firmware is the best option? What could go wrong if the imei have been changed?
Also, you just got me curious about the knox thing. Where do you suggest I look at for a comprehensive elaboration of the error codes?

This is a softbrick, if the hardware is fine then you should be able to fix it in 10mins by flashing a stock rom, but as the seller has sold it in this state then i assume it is softbricked for a reason so you can't test the device for example.

If the seller is not responding, then it points to them tampering with the device before selling it. Where did you buy it from, i would ring your bank as soon as possible.
Download the latest n9005 rom from sammobile and flash it through odin if you want to try and fix it, shouldn't really matter what csc as your knox is already tripped anyway so you can't recieve OTA updates or warranty from samsung anymore, mine is a BTU device but i have used many XEO roms.
If the phone isn't connecting to the computer properly like you say, then it's probably best to leave it. As this could result in the connection failing when it is flashing the bootloader or something. But if it works fine, then there should be no problems.
Here is something you could try, start up odin (i use v3.09), close all processes relating to kies, boot the device into download mode, that screen you provided pictures of. Plug the phone in and wait a few minutes to check the connection is stable, move the cable around to make sure the socket and cable are okay. You will see it come up on the top left in odin after windows has installed the drivers.
If this all works fine then flashing a stock rom should fix the device if the hardware is okay.

Just a quick question. From what site did you buy the phone and how did you pay for the phone?

1. Try flashing the new bootloader and modem first: http://forum.xda-developers.com/galaxy-note-3/general/odin-flashable-lollipop-bootloader-t3058101
2. If flashing modem and bootloader succeeded, try flashing the whole firmware again.
From what I learned from this http://forum.xda-developers.com/showthread.php?p=47287747#post47287747 thread, "invalid ext4 image" errors occur when bootloader is wrong.
Actually, do you have any info with what firmware was this phone last? I think I might have encountered another thread (don't remember it, though) which says that these exact problems occur when trying to upgrade from Jelly Bean 4.3 to Lollipop directly.

Thanks for the suggestion. I'll give it a try after a little more research.
I have no idea what the phone was before, or what the seller did to it since he's just not responding anymore.

So I tried flashing the new bootloader as suggested, it seem to have worked to some extent, but then I screw it up again by pulling out the cable before seeing "PASS!". What now?

From what I can see from you ODIN log, ODIN has "done its thing"
If you did not uncheck the auto reboot tab, the phone should now be rebooting.
And bootloader and Modem should be updated when its booted up.
Are you still stuck at the "Samsung GALAXY Note3 SM-9005" screen ?
Click to expand...
Click to collapse
I'm still stuck on the "Samsung GALAXY Note3 SM-9005" screen. However I do think that the "hlte_lollipop_bootloader_modem.tar.md5" has "done its thing". I was previously unable to get to the recovery, but I was able to get to this <3e>recovery after flashing.
Also managed to see some logs of "i'm not sure what it is" before the phone went blank. I presume its due to battery going flat.
Later, I tried putting TWRP on it. Starting with "twrp-2.8.3.0-hlte-4.3.img.tar". But being a novice odin user I mistakenly unpluged the phone when odin is showing "RESET!". Then I tried going into recovery using VOLUP+HOME+POWER, and got this screen instead. I'm not sure if removing the phone before "PASS!" in odin could have caused this? Subsequently I tried flashing "twrp-2.7.0.3-hlte-4.3.img.tar" and
"twrp-2.7.2.0-hlte-4.3.img.tar", which resulted in the same error screen about SEANDROID.
I also noticed it increased my KNOX counter?
This is before and after.
Next I tried flashing ""hlte_lollipop_bootloader_modem.tar.md5" again hoping it would fix it. It didnt work. Silly me, this flash does not have a recovery image in it does it?
Anyway, now I dont have a working recover and is still stuck on the "Samsung GALAXY Note3 SM-9005". Thankfully odin mode still work. What should I do next? Please see this thread below for a little background to my problem. Thank you.

SM-G900F Downgrade problem

hello everyone
3 days ago I bought a Samsung Galaxy S5 SM-G900F and the pre-installed OS was Android 5.0 Lollipop
I wanted to downgrade to KitKat 4.4.2 but when I flashed the 4.4.2 firmware at the end of The Flash the phone Rebooted but but there was nothing on the screen and the phone was stuck on a boot loop so I reflashed the lollipop firmware and everything worked
The question is it possible to downgrade to kitkat 4.4.2 knowing that the preinstalled firmware was Android lollipop 5.0 for rooting purposes to keep knox 0x0
thank you very much

The problem with using Odin to downgrade is that it doesn't fully erase what was on there before, it just overwrites it......
Did you try to wipe data in recovery after the flash? Sometimes this is all that is needed.
If you did, and it didn't help, then it may be necessary to flash a pit file at the same time as the firmware.
Before you flash anything with Odin, go to download mode to double check which model you have.....There have been a number of cases recently where devices have been 'rebadged' so that what is displayed on the sticker under the battery does not match what is displayed in download mode (download mode is correct).......

Is there any risk on flashing the pit file
I just want to know before I proceed
Thank you very much for your help

There's a risk to any flash, but as long as your device matches the pit file you flash, you should be ok.....having said that, flashing a pit file carries a potentially greater risk than flashing a firmware/rom as it 're-maps' the data partitions.....In the case of a pit flash, if the flash is interrupted because of a power cut off or a premature device disconnection, the phone will be absolutely irrecoverably bricked......

thanks for all the help

When I downgraded from LP to KK, the first attempt was unsuccessful, the phone wouldn't boot at all
I did nothing else apart from flash it again exactly the same way, the next boot was fine and I was back on KK
You might need to factory reset after flashing, it's possible some apps are causing problems with the boot if they are not compatible from LP > KK

Factory reset first then
But if the screen is just black, not even the initial logo, then something else is wrong
Why flash KK anyway, there is a MM stock ROM port available for the G900F now

I know but I wanted to root the phone possibly without tripping KNOX

If I do trip knox what would I louse aside from warrenty?

Nothing, I tripped mine ages back, everything still works
I read it might affect joining enterprise networks/domains, but never tried and don't use them
Try a different KK ROM, I assume you're trying the latest version atm?

It *might* affect OTA.....Some people say it does, others say it doesn't.....
But knox's main function is to prevent insecure devices from connecting to secure 'enterprise' business servers/networks.....basically if your employer expects you to be able to bring your device to work, and connect it as a business tool, you will no longer be able to do so.....*and* if the device was supplied by your employer, you could end up in all sorts of s**t with them too.....

Doesn't affect OTA, only custom (Root/Recovery) breaks OTA
Anyone saying tripped KNOX breaks OTA hasn't flashed back to 100% stock before trying to update OTA, unrooting doesn't reverse the custom status

Thank you very much for your help
I gave up I installed TWRP and flashed a custom rom
I couldn't resist any longer
I don't care about KNOX nor the warrenty anymore
Poeple are very kind in this forum
much appreciated for all your effort

Curious, why were you trying to downgrade to KK when Android 6 is available for g900f? I downgraded once myself (without pit file) to KK early on when LP was new, but Android 6 is a nice improvement over both imo. KK4.4.2 still has security issues, namely stagefright. If you're happy with custom rom, so be it, just curious if you were (or not) aware of Android 6 availability for your device, incl debloated, stock based knox-free ROMs.

I wanted to downgrade to KitKat 4.4.2 but when I flashed the 4.4.2 firmware at the end of The Flash the phone Rebooted but but there was nothing on the screen and the phone was stuck on a boot loop so I reflashed the lollipop firmware and everything worked
The question is it possible to downgrade to kitkat 4.4.2 knowing that the preinstalled firmware was Android lollipop 5.0 for rooting purposes to keep knox 0x0
thank you very much
