Hi Zarg00
I had the same problem as you a few days ago! Nothing seemed to work, wheter I tried wiping the cache/dalvik chache or doing a factory reset.
With Odin I managed to get it back to life again.
Don't worry, it's easier to repair as you might think. =)
You should have your original Samsung usb cable ready.
Unbricking Samsung Galaxy S4 by Installing the Official Firmware:
If wiping the data/factory reset, and cache partition does not help you, or you are not able to boot into the Android System or ClockworkMod recovery on your Galaxy S4, you can try installing the official firmware on your phone. Read the following guide that will help you find the correct firmware for your Galaxy S4 and install it safely.

Unfortunatly I can't post you the link directly, because my post count isn't high enough.
But try searching on google "droidviews how to unbrick galaxy s4" and it should be the second post with the very well written tutorial.
After you are done with it, your device should work correctly again.
You will lose your recovery and root though.
Good luck and report back, if it worked! :good:

Maybe not the first thing to do but have you tried flashing in the stock rom with odin and then do the updates again?
Sincerely, Joakim

im gettin Official Firmware now, so i think XD its 1.6 gb so its gonna take a while,
i realy hope this is gonna work

In my case i even had to restore the PIT, too. But try just flashing the official firmware before that.
Yeah, downloading the firmware can take a while. You can download the newest Version [I9505XXUBMGA Jelly Bean (4.2.2)] on google drive as well.
Just delete the "_" after https: in the link -> https:_//docs.google.com/file/d/0B7DKa-PuA5IlcVY2MGtMT1ZJMHM/edit
Drive lets you download faster than hotfile.
Its the DBT version though, so you might need to change your language from german to whatever you want at the first start.
But since your galaxy is still able to boot, the chances are really good that it will work well again after you have flashed the official firmware!

im kinda stuck at this
Boot your Galaxy S4 into Android System Recovery mode: hold Volume Up+Home+Power keys together till the screen turns up and the Samsung logo blinks twice. Just as you see a green Android bot, release the Power button but keep Volume Up and Home keys pressed till you see the recovery menu (see below). In recovery mode use the volume keys to scroll and power button to select options:
Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it.
i cant go to recovery mode, i can see little blue letters in upper left corner but phone resets -.-
any hint ?

Which recovery are you using? The "official" recovery did not work very well on my device. It just crashed when I tried to wipe cache partition.
Try flashing CWM Recovery for GT-i9505 with Odin.

uhm im confuzed, can you walk me throu i kinda dont get that "odin" program
dunno what to do with that files you show me :S

Don't worry, it is not that hard. =)
I guess you already flashed the official firmware with Odin, right?
To install cwm recovery follow these steps:
1. Make sure that your device is at least 50% charged
2. Power off your S4. To make sure that it is really off pull out the battery for half a minute and put it back in.
3. Start Odin3 on your PC.
4. Download the recovery file (link in the post I made before ^^) you should choose the one i marked with red in the screenshot below.
5. Okay, you have the recovery file and odin3 ready. In Odin, click the box before "PDA" and than click on "PDA" and choose the file you just downloaded. It should look like in the screenshot below (sorry, that it's in german, but I thought it might help you )
6. Now we have to prepare your Galaxy S4. Press and hold "Volume down" + "home" and then press "Power" to get into download mode. It will ask you, if you are sure. Just press "volume up" once.
7. Connect your phone to your PC with the USB Cable. Odin should recognize your device. Just make sure, that the ID:COM port turns blue.
8. Click on start and wait till your device reboots and Odin shows you the PASS! message. You can disconnect your S4 from the PC now.
9. And now try to get into recovery mode again by pressing "volume up" + "home" + "power". Sometimes you don't even have to press the home button, just try what works best for you. Release the power button as soon as you see the logo, but keep the "volume up" button pressed until you are in recovery mode.
If you can enter recovery mode again (and i'm crossing my fingers, that you can ^^) just continue with the tutorial from droidviews and wipe data/factory reset and after that cache partition.
I hope that helps! :fingers-crossed:

this works, thanks,
i did "Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it."
well that whas kinda the last thing i needed to do, but its still the same,
he shows me Samsung galaxy s4 gt - i9505 logo and keeps reseting ,,,
so this didint fix my problem

Damn.
Did you also flash the PIT files? I would do the whole process again, but this time follow "How to unbrick S4 by Flashing Stock Firmware and PIT File".
If that doesn't work as well, I guess it is some hardware error. The good thing is, that you did not lose any warranties by following the tutorials and you can return your phone to the shop and claim a repair.

so basicly i did all over again its still the same phone keeps resetting
but in recovery mode i noticed after i do this
"Go to “wipe data/factory reset” option and wipe it.
Then “wipe cache partition”.
Finally, go to “reboot system now” and select it."
when i want to reboot it says " Root access is missing. Root device ? "
basicly there are lots of
NO
NO
NO
NO
YES - Root device (/system/xbin/su)
i hope this helps you so you can help me :S

gonna test it for a while and post here again if all works fine

aaaaannnnnddd nothing, it resets
im back at the beginning ,,,, he whas working fine for about 10 min then he just shuts down and resets all the time ,,,,

Hey Zarg00 =)
Did you restore the PIT file as well this time? You phone shows a really strange behavior. O__O
I have found a thread here, which might hopefully help you [Guide] How to unbrick your phone.
Sometimes flashing files with Odin won't work the first time and you have to try it multiple times.
If that all doesn't work, then I guess it is not a software but an hardware issue. :/

well i made it work, and its fine now, but it restarts sometimes ,,,
also Kies cant see my phone, its stuck on connecting ,,,, i can browse it throu My Computer i see it there

Cool! It finally works now? Did you do anything different or just the steps from the tutorial again?
Kies never really worked for me. Sometimes it didn't recognized my device at all.

[Q] i9505 s4 button problems

hi, I have just registered and looking for some help if at all possible,
I have a galaxy i9505 S4 and recently the Home button seems to come and go, and the power button the same, and also the screen keeps lighting up every minute for about 10 secs, if i remove the battery I can restart the phone, and also the home button works to start the phone in factory reset mode, so i feel it might be a software problem rather than hardware.
is there any way to get the phone to reinstall the firmware, as factory reset didnt help
the phone is on orange (EE) UK
thanks for any advice or help given.

hi, thanks for the reply,
the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine.
on and off the power button dont work, and i have to remove the battery to restart it.
the screen just lights up every minute for about 10 secs as if it has a notification, but there is nothing there, it drains the battery to empty in about 5 hours.
cheers.

Reboot yr phone.

hi, I have just done upgrade and initialisation from Kies, and it redownloaded and reinstalled the latest software, took ages, and the button is still not working, so i guess it will have to go to the shop.
cheers for all your help, the button only works before the OS has started, as i can get into recovery menu.
thanks again.

mechanical or hardware problem
That seems pretty much a mechanical problem (button broken) or hardware issue (shortcut somewhere? could explain the screen problem...)

the buttoon does work, but only to get the phone into recovery mode at startup, so physically the button works, just not when the phone is powered into the android os.
Im a bit out of ideas.

It's a faulty button mate.
You don't need to use the home button to boot to recovery or download mode on the S4.
You can simply press volume up+power (recovery) or volume down+power (downloadmode) no need for home button at all.
This is why you think it works.

It's very true mate.
YOU DO NOT NEED HOME BUTTON TO BOOT TO RECOVERY, SIMPLE.
Your issue sounds different to the OPs.
If you refer back to his first post, he said his power button doesn't do ANYTHING.
"the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine"

[ROOT] I can't root my GN3

Hi
For the beginning i want to say thx to the people who will try help me.
Samsung Note 3 SM-9005
Rom: NB3 4.4.2 (kitkat)
I should post it as a reply to the chainfire's post on cf auto root but i can't cause i am a new on xda (and he didn't allow me )
So what is my problem ?
When i tried root with CF all is ok but when odin say 'PASS' there is no recovery boot (the install process, the red android logo)
What i have ? > After my flash my phone try to boot (with Se Enforcing + 2 other stuff blue red and yellow i guess) but my phone can't boot (yes even boot) he only reset and try re-booting.
chainfire's say
*NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.*

So i tried it, i unchecked the auto-boot, flash my phone pull the battery and press the button (without the battery), and after my phone turn off.
When i turn on >> same issue boot loop all time
And to have access on the phone i must go on the downlaod mode and click restard phone...
Well if u could help me .... 90% of my app require root x) :laugh:

Is this the file you used? There's 2 files, one for 4.4 and the other for 4.3. Try flashing the file again.

Yes i used this file
i forgot to say that kingo root is so buged i mean i try also to root with him (on 1s)
He put my phone on download, install the recovery ect
Result: a fake root, in fact even if i have SuperSU (he installed) He said me that i have no binnary installed
I also checked on "Root Checked" no root here
BUT on download mode: custom os + custom binnary
And his chinese recovery work
1 hour ago i used my GN2 to see if maybe it's my computed who have issue with kingo root
Result: Root perfectly my phone
I also forgot to say that i used different odin (1.85,3.09 ect) on admin
And i tried the NA6's rom (maybe was the rom ^^' but nop still no root)

I re-read your reply and I'm a little confused. Did you pressed all buttons after removing the battery? Also, there is no restart phone in download mode, you can only get out of download mode by pressing power button for a few seconds or remove the battery.
Lastly, maybe check you have the correct samsung usb drivers and reactivation lock is off.

Well i know but i didn't even really understand the process to manually boot the recovery (the chainfire's quote)
what i did ? i flash my phone when odin say "reset" i just pull the battery on the table and next press buttons (Volup+home+power)
My phone turn off i replace the battery and i get the booting loop
Maybe my way to process is wrong, i don't even know chainfire don't really explain in details the way to do it....
For the driver i deleted all and re-installed by kingo but in fact all time my device is detected (in all mode) and COM if alway here (also the flash is correct)
I think maybe my process is badly done (maybe i can't understand cause im french)

Here's how I would normally do it.
- download the file and extract to a folder/location of choice
- put phone in download mode by pressing power + vol down + home button all at the same time until something comes up on the screen then let go of the buttons then press vol up then connect to usb on pc
- go to where you extracted the downloaded file, open odin and put the tar.md5 file in the PDA slot and click start
Odin will flash file and automatically restart to apply root ( red android with red letters ) then restart again to android.

OMG dude that work thx to you :laugh::laugh::laugh::laugh::laugh::laugh:
Ok the last post i mean i didn't understand the process of the boot recovery manually (with autoboot unchecked)
But i least this time i used a different thing- what ?- A nokia usb cable
And this time that work and im sure before i did all u said to me.
I worked on 2 night x)x)
Anyway dude thx to help me

No problem.
Enjoy your phone :good:

Recovery Is Not Seandroid Enforcing

I tried to root my phone S7 Edge 6.1.1 just a moment ago using ODIN and CF Auto Root. I got the PASSES! sign in ODIN but upon phone rebooting I am stuck on the Samsung S7 Edge logo screen with text in red 'Recovery Is Not Seandroid Enforcing" up the top.
At this time I am unable to turn my phone off, when I do it just turns back on and goes to the same screen. I can't get into download or recovery mode either.
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Also thought I should add, my phone doesn't get registered when I connect it to my PC either, it wont show up in ODIN so I am unable to flash a stock recovery at this time.

It's trying to boot into recovery.
When you say you rooted with CF Auto Root, what did you do precisely? And did you follow Chainfire's specific instructions regarding the lack of screen output during the process?

Thanks for the reply.
I used CF-Auto-Root-zerolte-zeroltexx-smg925f.tar to root.
The steps I used was to simply put my phone into download mode and use ODIN to flash the file mentioned above. That is as far as I got unfortunately. I did this once before, a few month back when I first got the phone with no issues. I remember having to install TWRP but I couldn't remember if I did that pre-root or post-root. But I think that is where I went wrong.
Now I am unable to do anything with my phone. I can't turn it off, get into download or recovery mode. When I hold down VOL UP+POWER+HOME it just resets the phone back to the samsung logo screen.
Any ideas on what I could do?

You used the CF Auto Root file for an S6 Edge.

OH GOD. You're right. I just realized that. I was supposed to have them saved into their own folders but I guess I saved that one too the wrong folder.
So what does that mean for the life of my phone then? Is it toast or is it recoverable somehow?

What is your model? Is it the SM-G935F? If so, first things first, download the correct CF Auto Root file for your device (here) and try again. Press VOL DOWN+POWER+HOME and it should reboot into Download Mode. Then try to flash the correct file in Odin again.
These phones are very difficult to hard brick, especially with something like CF Auto Root so you should be ok.

Yes, it is a SM-G935F. Unfortunately I am unable to reboot the phone into Download Mode. When pressing VOL DOWN+POWER+HOME it just takes me straight back to the Samsung logo where it says "Recovery Is Not Seandroid Enforcing". I'm hoping that once the battery drains completely I will be able to boot into Download Mode again.

Try simply resetting it instead. Press volume down and the power key (don't press home) for around 7-10 seconds. Once it starts to reset, remove your fingers from the buttons very briefly then press volume down, home and power to enter download mode.

That hasn't worked either unfortunately.

I just found this thread from a guy having a similar problem. He just had to wait for his phone's battery to drain completely and then he was able to enter download mode again.

You shouldn't have to though. If you can get the phone to reset at all (even if it's to make another attempt to go into recovery) then providing you time it right, you should be able to get into download mode. Did keeping your fingers on just the volume down and power buttons do anything? Keep them on continuously for up to 20 seconds and see what happens. Did you say pressing vol up & home & power made it reset and try to again get into recovery? What happens if, as soon as the screen indicated it's resetting, you remove your fingers and quickly press vol down & home & power instead?
Anyway, even if you have to wait until the phone dies, getting into download will be possible eventually. Then worst case scenario would be you having to reflash stock back. Or, as would be my preference, flash TWRP then flash a custom rom zip like Superman.
Just to confirm, I take it you selected OEM Unlock in dev options?

I have never had any trouble getting into recovery or download before so I know the method. But just the properly clarify for you I will explain some of the combination I have tried without success. Bare in mind the phone is constantly turned on and idles on the Samsung logo.
I have tried:
Hold VOL DOWN+POWER+HOME, the phone resets and goes back to the logo.
Hold VOL DOWN+POWER, same as above.
Hold VOL UP+POWER+HOME, nothing happens at all.
Hold VOL UP+POWER, same as above.
Hold VOL DOWN+POWER+HOME, release and repress all on black screen, just goes back to logo.
Hold VOL DOWN+POWER, release and hold VOL DOWN+POWER+HOME on black screen, just goes back to logo.
and numerous other things like random combination to try and enter Download or Recovery mode, which have all failed.
Right now it's just stuck on the Samsung logo and staying there, taking forever to drain battery. I work in the morning so hopefully it is dead by then and I can get into Download mode.
Have already started download stock firmware in hopes that I will be able to flash it after.
Thanks a bunch for your help. If you think of anything else I might be able to try let me know!

Oh wow. 100+ attempts and I followed your last post about holding for up to 20 seconds. I was waiting ~5 seconds and releasing thinking that it hadn't worked.
Finally go into Download mode and will flash stock firmware and let you know how I go.
Thanks again! I owe you a cold one.
EDIT: Was no need to flash stock firmware. Just flashed the proper version of CF Auto Root and it worked. Again, thank you so much!

Fantastic. Hope you get it sorted.
On a side note, you have probably already tripped knox and you will have lost you OS data and possibly even what you have stored on internal storage. If so, I suggest you install TWRP, format data (you will lose everything with this but it removed encryption) and install a custom rom like Superman 1.9 from your external SD. It's better than plain stock and comes pre-rooted with plenty of other mods.

I can't get it to work? What keys did you held down?
This is how my screen looks

I tried to root with Odin but I think I might have failed. How can I undo this?

recovery is not seandroid enforcing
hello,
my S7 Edge was rooted with cf-auto-root and worked fine but after 2 monthe I've installed LBE_Security_Rel_6.1.1928_A1_DE_v5_signed and reconized the message device is not tooted.
I was not very clever and cofirmed the question "fix the root problem" I don't remember exactly the words. After that root was gone.
I've flashed the stock Fw G935FXXU1APD1_G935FDRE1APC3_DRE but I still have the message "recovery is not seandroid enforcing" after trying to root with CF auto root.
AP:G935FXXU1APD1
CP:G935FXXU1APD1
CSC:G935FDRE1APC3
Is there any way to get root again
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Simply hold down Home + Power + Volume Down for 10-15 seconds - don't release when the phone initially reboots and gives the same error, keep them held down and download mode will appear. I have to hold for 11 seconds, a strangely unrounded number.

Hello Guys I have this Same issue Yesterday....... This happens when you flash outdated CF Autoroot. CF Autoroot Updated on 25/08/2016... Download it...
Fix for Stuck in Logo Screen
Just Click and Hold ...... Vol Down + Menu + Power Keys ...... DO NOT RELEASE. IT Will Restart. DONT release. It will restart again and you will be download mode.

i found this during the rooting process. its a bit different to older samsungs on the s7 / s7edge. YOU HAVE TO KEEP HOLD OF VOL DOWN + HOME + POWER until it enters download mode, which can be 20-25 seconds

[Guide] How to root N20

How to root N20 (N985F/N986B/N9860)
WARNING!
Before you root your device you must be aware that
This will void warranty.
As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but some ROMs are patched for all these mentioned features, you can use custom ROM or patch it yourself for stock ROM. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
OTA won't work once you root device.
ROOT with caution.
You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.
How to Unlock Bootloader
Follow below four steps to ulock the bootloader
1.Enable Developer Option
Open the Settings app on your Galaxy device.
Choose About > Software Information.
Now tap on Build Number 7 times to enable the developer option.
You’ll get a message “You’re now a developer.”
Now Developer option has been enabled.
2: Enable OEM Unlock
Go to the Settings app again on your device.
Navigate to the Developer option.
Enable the toggle next to OEM Unlocking.
Tap YES to turn on the confirmation dialog box.
3: Boot Your device to Download Mode
While device is booted → Connect device to PC → Select to Restart → As soon as device screen turns off, Press and hold Volume Up + Volume Down simultaneously OR In case device is powered off Press and hold Volume Up + Volume Down simultaneously and connect your device to the PC via a USB Cable.
You can see the warning message on your device and release the pressed keys.
Finally, press the Volume Up key once, and you will be booted into Download Mode.
4: Unlock Bootloader
Once device booted into Download Mode, you will see option to long press Volume up to unlock bootloader,Now, press and hold the Volume Up key for a few seconds., Here, you’ll get a confirmation whether you are sure to proceed.
Use the Volume Up button to reply to the confirmation.
This will erase all the data on your device and unlock the bootloader.
Once completed, your device will automatically boot up to the OS.
Now you have successfully unlocked the bootloader
How to root
Instructions for stock non rooted ROM​
Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.
Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
Install Magisk apk
Press the Install button in the Magisk card
Choose “Select and Patch a File” in method, and select the AP tar file
When done, copy patched file to PC
Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.
Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.
Install the Magisk app you’ve already downloaded above and launch the app. It should show a dialog asking for additional setup.
Let the app do its job and automatically reboot the device. Voila!
Upgrading the OS​Once you have rooted your Samsung device, you can no longer upgrade your Android OS through OTA. To upgrade your device’s OS, you have to manually download the new firmware zip file and go through the same AP patching process written in the previous section. The only difference here is in the Odin flashing step: do NOT use the CSC tar, but instead use the HOME_CSC tar as we are performing an upgrade, not the initial install.
Important Notes​
Never, ever try to restore either boot, recovery, or vbmeta partitions back to stock! You can brick your device by doing so, and the only way to recover from this is to do a full Odin restore with data wipe.
To upgrade your device with a new firmware, NEVER directly use the stock AP tar file with reasons mentioned above. Always patch AP in the Magisk app and use that instead.
Never just flash only AP, or else Odin may shrink your /data filesystem size. Flash AP + BL + CP + HOME_CSC when upgrading.
PS : It is strongly recommended to make EFS backup once you root device and save to safer place like on cloud or PC
For TWRP : Read here

Mostly U version is Snapdragon with unlock bootloader and not rootable. Confirm first if you have unlocked bootloader.
Also last 3 digit of firmware is weird. Which device is this? Can you post screenshot of phone info?

What I guess, here unlocked means sim unlocked NOT bootloader.

Some people might need clarification. An "unlocked" phone is not the same as a phone with an unlockable bootloader. If it's the same pattern from the past several years of Note releases. All of the snapdragon US versions won't have the ability to have their boot loaders unlocked, therefore a root. This root method most likely applies to the non-US Exynos versions. If you live in the US, and ordered your phone through Samsung or any carrier, it will be the snapdragon version. I hope I'm proven wrong.

Hi thanks for the rooting instructions. I would like to know if you or anyone has gotten the option for s pen pointer under air commands in your note advanced settings? Jimmy is promo does but every other youtube doesnt have that option so im wondering what note 20 has it and what firmware? Anyone feel free to chime in

If you have rooted the Note 20 ultra 5g (Germany), can i start it normally or do you have to hold a key combination?

If you root with Method mentioned in OP, you should able to boot with root without using combo keys

I coming from the note 9.
If it's rooted, how do I update it?
(Switch from csc to talk (Vodafone DE to DBT) I know that has nothing to do with this topic )

Plz post your question to appropriate forum

ok a new topic, "how do i update a rooted note 20 ultra 5g" Ok I'll do it as soon as I have mine.

no one has the S pen pointer option?
Also have any of you signed up for beta 3.0 android 11 for the s20? Im guessing you guys have early access because the note 20 isnt even out yet.
