Boot into system recovery, you can't rely on the various apps to show you as most of them just lie and say it's not tripped..
System recovery
1. Turn phone off
2. Hold volume up+home+power
Knox should read 0x0
Then just choose reboot.
Not sure there's any way you can do it in advance to buying the device
Since recovery can also be modified, I'd say download mode is the safest way to confirm. Same key combo but using vol down.

recently the power button on my nexus s(i9020) stopped working (all of a sudden). i was managing till now with cm7's volume wake feature. Now im thinking of getting it fixed under warranty but i need to unroot the device for that.
problem here is all the instructions i can find need the power button to navigate through the recovery menu. i have to unroot AND flash a stock rom without the power button!
i dont know what to do :'(. pls help!
You're going to need the power button to re-lock the boot loader - no way around that.
You can use fastboot to flash a stock AOSP system (/system, /data) and erase userdata, but you're going to need that power button to confirm the lock.
okay, so basically there's no work around with it ... thanks anyway. will they atleast fix it for some cash? i mean without the warranty?

Even unlocked they may fix it under warranty - if it's an obvious hardware issue. The language when unlocking states that it may void the warranty. Even on the Nexus One (which said it does void the warranty) I got a bad trackball fixed under warranty when I told them it was only broken due to being in a car accident.

i use the twrp recovery instead of clockwork. my power button is dead too. you dont need the power button to select in the twrp recovery. also, to select in the bootloader since im without the power button, i firmly flick the back of the phone with my finger right under the lens. that works every time for me, and i spend a lot of time in recovery and in the bootloader when testing out kernels
thanks guys. i just downloaded the beta version or whatever u call of the next clockwork mod and it supports the capacitive keys! yay! ill be handing it over to samsung today. lets see what happens
I'm a newb to Android so please forgive me if I don't have my terms correct. Long story short, I returned my Skyrocket to stock using Odin3 v1.85 with the SGH-I727-UCKJ2-k0nane.tar and got a PASSED! result.
By the way I had a hell of a time getting it to go into download mode. The three button solution would not work for my device (kept going into recovery mode). If anyone else has this problem I had to remove the battery and SIM card. Hold Up/Down Volume while plugging in the USB cable (no need to hold the power btn).
I need to take the phone to AT&T because the data service isn't working and I was wondering if they can tell whether or not it was rooted before I used Odin to unroot. How do you read the binary counter to see if my Flash count is correct? I'm assuming that's how AT&T would check the device to see if it was ever rooted.
If there is another thread regarding this I apologize, please point me in the right direction.
Thanks in advance.

The three button trick is not supposed to be used for going into download mode.
The volume + usb at the same time is.
Three buttons is for going into recovery mode.
One of those two modes should show you how many times it's hit the counter. I don't remember which. But I saw it just the other day.
I took my phone in to ATT to get a warranty replacement for some screen issues.
They never even looked at the phone, other than for me to show them the issue with the display. But if you're having OS issues then they may (or may not) look at this as a source of the problem.
What's wrong with your data service?
OP, power off your phone and pull your battery. Plug it back in and then hold down both volume keys while plugging in the usb cable which is connected to your computer. Continue holding the vol keys and you should see a download screen. Let go of the buttons and then tap vol up. You should see the counter here.
Sent from my Samsung GSII Skyrocket (SGH-I727) using xda premium
The 4g icon mysteriously disappeared and I could not get access to email, web or any other data related service. After I unrooted and restored to factory default the data services began to work again. I originally rooted so I could enable tethering (and it worked) but after reading several articles and threads regarding AT&T cracking down I decided not to put it to use. I may root again at a later date when cyangenmod has a version that works with the Skyrocket but my understanding is the current version wont work with the Skyrocket. Thanks for your help.
Rooting does not affect your data. You can use a rooted stock rom. Did u incorrectly flash a rom or restore apps and system data ?

Take a look HERE
The short simple answer is this counter doesn't count ROM flashes, it count binaries and Odin uses. The easiest way is to buy a jig from ebay and reset the damn counter. No other way around it as far as I know.

can someone describe what this counter is, what it counts and if its really a big deal? I'm new to android coming from a few years with iOS, does the counter really matter? will att not take it back if this counter is > a certain amount?
with iOS i'd just flash back to stock and bring it in to get it warrantied out. now, knowing there's some sort of counter i may question what roms to flash if i can't get the counter back to zero.
Hi,
I have the I727R with Rogers.
I flashed a rom once (kernel included) with CWM recovery and install zip from sdcard. Now I'm back in stock mode.
I never used odin.
I try to enter into the download mode as you mention, but none of the methods described here work.
Hold down volume + and volume - at the same time and plug the USB cable brings me in recovery mode. such as holding the power button. hold down volume + and connect the USB cable up the phone to recharge. The only way that works is to hold down volume - and press the power button or plug the USB cable. the two ways gives the same result.
And when I got download mode (mode odin). I see "CUSTOM BINARY DOWNLOAD: NO"
To return to stock mode, I used the recovery option from CWM recovery.
Is it normal that my counter is still at 0?
Hi,
When I tried turning on my Galaxy Note Pro 12.2 this morning, it didn't work, as if the battery was completely flat. That was unexpected as I though it was almost full. When I put the tablet on charge, it started in Odin mode writing "Downloading... Do not turn off target!!".
Now when I press the on/off button for something like five seconds, it reboots. If I press on/off + vol down + menu, then I enter a menu giving me two options: continuing or rebooting. In both cases the result is the same: going back to the Odin screen. Here is the exact output:
ODIN MODE
PRODUCT NAME: SM-P900
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX WARRANTY VOID: 1
RP SWREV: A1
The tablet was rooted one year ago and I haven't play with ROMs and firmwares since then. I have absolutely no idea why it started in Odin mode.
I am currently downloading a firmware to try upload it to the tablet using Odin. Is it a smart move? Any advice?
Make sure your volume button is not stuck. Test it when the tablet is off to see if it response normally up and down.

It seems OK to me. Moreover, if I start pressing on/off + vol down + home to enter the Odin menu, I get two different behaviors pressing vol up or vol down: either reboot (and then Odin mode) or going to Odin mode. So I think these buttons work fine.
Are you able to get into recovery?
If it were me I'd try to run through the root process first, reflashing the modified recovery. If that doesn't fix it then yeah most certainly a full wipe would work since you're still able to get into download mode anyway.

So basically, I try to root again my tablet as I did the first time? (Sorry for these questions, I'm not very fluent with all these things.)
I can't flash anything using Odin. It gets stuck at the "Initialzation.." step. I tried different versions of Odin and different USB ports (but not cables, I only have one). It might be related to the fact that I'm using Virtualbox. I will try to find a native Windows.
In the mean time, any idea?
Hi, so i have bought s7 and everything seems to work great,only i haven't noticed till now that it shows s8 logo when i turn it on. its not much of a problem, i just want to know how to bring back original s7 boot logo? I dont have much knowledge about rooting and stuff so i dont know is the phone ever been rooted ,or does it need to be rooted to change that logo. I hope u guys (and girls ) understand my not so great english
Press the Power button + Home button + Volume down button, all at once, while your device is powered off.
There you'll have to look if it says Knox 0x1 or Knox 0x0.
0x0 - Knox not tripped
0x1 - Knox tripped
All those beyond this line messages prove root:
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX WARRANTY VOID: 1
Installing a custom recovery will trigger Knox.
If you are not rooted, I recommend not rooting.
To reboot, press Power button for 5 seconds, or Power button + Volume down button for 5 seconds.

First check which model S7 it says in Download Mode
(Volume Down & Home & Power)
Once you know which model it is, download the correct firmware from updato.com firmware section
Load all 4 parts into ODIN, connect phone to PC USB and hit start
ODIN 3.12.7

If you choose CSC it will wipe the phone after flashing, probably the best idea as it is currently custom
HOME_CSC will not wipe
Only use CSC or HOME_CSC, not both
You have good advices here. Since you are rooted, you can easily flash what ROM you want. Then you can play with it and make your own customisations, like custom boot animations.
Enjoy.
I have a rooted s10E , with magisk and xposed. I thought i read somewhere that you can now boot into root without holding the two keys down, does anyone know if this is true or where I can find the thread on this ?
thanks
yes you don't need to use button combination if you are powering up after phone has been switched off ie power off, but if you use the restart button you will need to use the bixby volume up buttons
