[Q] Strange: Boot logo stuck, no recovery mode.

Hi guys,
Been a samsung user since S2, unfortunately ive made people bring me their devices so i can polish them, if not fix.
I got an i9505 at the moment with a very strange issues:
It boots up, hangs on the boot logo.
It boots in Download Mode, but volume up button wont work, i've opened the device and yet the button was fine.
Sometimes just connecting it to the PC using USB, the device vibrates as if it's turning on, though it vibrates every 2-3 seconds. Device is Off btw.
Recovery Mode wont boot, Home Button + Volume Up + Power Button until the thing vibrates, i release the power button, and it just hangs there. Makes me doubt it is not even reaching the point where it knows where the recovery is. However, i got it in to the blueish "booting recovery..." once, but it hanged there as well.
Am clueless here, (re)searching usually brings me near the answer, but it hasnt, i hope the answers here will do it for somebody else.
Edit: since i am doing this out of pure compassion, i have no idea what is loaded inside .

Flash a stock rom base in your country mate via odin and you can download it from here http://www.sammobile.com/firmwares/2/ , then once your done downloading the file, Boot into Download mode (Power+VolumeDown) , Open Odin select PDA /AP , Connect both cables (Wait until you get a blue sign in Odin)and flash away.If you encounter any issues with the firmware (Any FC, Bootloop etc)Boot into recovery mode (power+vol up),Choose to wipe/factory reset. (THIS WILL ERASE ALL OF YOUR DATA INCLUDING YOUR INTERNAL SD CARD! Then choose reboot and you should be good to go! Have a nice day

Mate, is there a way to flash through Odin without pressing the Vol Up button, cause i am not aware of that?
I cant get past the first point of download mode, to actually enter you need to press Vol up.

try to remove your battery for 10 sec and put it back mate , and then try O press and hold Power+Volumedown to see if you can boot it. or you can try to connect to kies 3

Already done that tbh. Battery was off for like a day. I was hoping for that qualcomm boot mode, but doesnt seem to work.

Hence the thread. There was no other option left.
I usually do this to gain the knowledge for future use, is this a common death for the S4. the user that had it is definitely not a flasher, what couldve gone wrong?

[Q] stuck after installing 5.0.1 factory image

Update: I was able to get it recognized via fastboot and used NRT to flash back to stock under the bootloop option.
Now rooted with factory 5.0.1 !
The way I got it to recognize the tablet was to press the middle part of the volume switch (effectively pressing up AND down volume) and the power button and then the bootloader loaded and I could use fastboot but not adb. I read in another thread about pressing the middle of the sound button. Never heard of that before.
Hopefully someone can help me out.
i updated via abd using the flash all script. Now when it boots up it's stuck on the logo of flying color dots. (yes, I waited 15-20 min at least)
Anyway, now I can boot into fastbboot mode but the computer doesn't recognize it.
If I try to boot into recovery (which I think got corrupted) then I just get the android icon with a red exclamation point.
I have no way to clean anything up cause I can't communicate with it.
Edit: I'm stuck in a boot loop also. If I just let it boot it stays on the logo forever. When I try to turn it off it just reboots to the logo.
If I use the keys to boot to fastboot it just sits there and now I can't even change the option at that point and there's no way to completely shut it down!
Thanks for any assistance you might have.

Pressing both volume buttons and the power button will get you into fastboot mode. It's always the last fallback position and I've never known it to fail. I had the same with a bad flash on Tuesday when trying to solve my wifi problems.
Glad you got it sorted

Thanks.
I was getting to the bootloader screen but couldn't get the PC to see it. I always used to use power/vol down combo to boot into bootloader and didn't even know u could press both vol up and down at the same time.
Or maybe I'm imagining it all.

S5 SM-G900F Soft-/ Hardbrick?

Hi all,
I've tried to downgrade my S5 from most recent Kies lolipop to kitkat (G900FxxxANCE from sammobile). After odin pass the phone reboots (at leas it seems so) but does not show up on screen - so screen is black and no chance to do anything - the blued led comes up.
I tried some tutorials without success (last try: remove battery - powerbutton - wait). Do you
a) know whether it is a soft or hard brick?
b) any workaround?
If you answer to this I would be very glad since I'm currently a bit nervous.
Thank you and regards so far.

No, not really. Or I don't really know since the screen doesnt show anything. I've read that the blue led stands for entering download mode.
Well, at least odin recognizes the phone when plugging in while the blue led is on.

If you had a successful odin flash, you should have a recovery.....
You need to (at least) try to get into recovery.....sometimes, in cases like this, wiping cache and factory resetting (maybe a couple of times) is enough to get the phone to reboot......
If it doesn't work, going to download mode and re flashing your LP firmware may be necessary.......

The screen is plain dead. It does not react in any way. When I "start" the phone I don't see anything except the blue led in the upper left corner on the phone itself.
I'm not sure if its booting into recovery (I've read that the blue led stands for recovery mode though).
The only thing I recognize is the successfull connection in Odin but I can't flash again since it hungs in "Connecting..."-state.
Regards.

Remove the battery so you know 100% the phone is off
Replace battery
Press and hold Power Down & Home & Power until it enters download mode
If nothing appears on the screen after a few seconds (Give it about 5+ seconds of holding the buttons down), then it is likely a hardware issue
Possibly the phone itself, but also possible one of those buttons is not working

Thank you. It didn't work in any way. I've tried to connect via ADB and factory reset but I can't establish a ADB connection. I connect the device and windows tells me "Installing drivers" (Drivers are installed) but fails in the end. So I guess this is the fault. Whatever.
I can't tell in which state the phone boots as I only see the blue led (its just turned on - no blinking).

Sounds like it's time for the old repair shop unfortunately

i have had the same problem when i downgrade to kitkat to fix it download a lollipop rom from sammobile then u have to :
-remove battery put it back
-press Home + Power + Volume Down buttons
-screen will be black no problem press up arrow to continue to download mode
-connect phone to usb
-open odin u will see it is connected
-flash lollipop and u will be back
i think it is a restriction for lollipop because u will root the phone on kitkat with tw.apk
if this not will help i have another solution just try it same problem to me and i figured my self to fix the problem

Hi all,
i have the same probleme with my sam G5.
after flashing back the lolipop stock rom 5.0 the phone seems to be working properly except for the screen that shows nothing; windows detects it as MTP device and i can get in and see all the content inside of it, also when i assimilate entering the download mode (volume down + Home + power then after few secondes Vol up) it goes well since odin detects it and flash it (but always there is nothing that shows up on the screen),
any ideas or hints ??

If you want to downgrade to kitkat from lollipop,then flash kitkat modem and bootloader for your device,you can search on the xtrestolite post,the developer put bootloaders and modems for each g900* device for kitkat and lollipop roms.

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?

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

LG G2 Boot security error after trying to flash SuperSu after going to LineageOS 14.1

I've been using Cyanogenmod 13.1 (rooted) and I decided to flash a ROM with Nougat. I flashed lineage-14.1-20170320-nightly-d802-signed and open_gapps-arm-7.1-mini-20170325 and everything worked fine except I didn't have SuperSU. I tried flashing SuperSU-v2.79-201612051815 and when I tried to boot into system I got this screen (with the LG logo below) http://i.imgur.com/O7vOtab.png I tried many methods like this https://forum.xda-developers.com/showthread.php?t=2582142 and this https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 to no avail. In Linux when I used the ls /dev/sd* command in the terminal the phone wouldn't show up and later in Windows I got the PC to recognize the phone as Marshall USB Composite Device 9006 http://i.imgur.com/a5WHV9P.png and in Disk Management the phone partition shows up un-initialised http://i.imgur.com/XaVKIu7.png . Help I don't know what to do now. Tell me if I should provide more information.

I had the exact same problem. Then i found a solution. Just dont flash the normal Supersu, you need to flash the Supersu BUMPED file. Just go in recovery, press 10 sec the power button to be sure the phone is off, then hold volume down and power button until the logo appears, then release and press again (fast) then choose yes, yes. Just flash the Bumped and if recovery asks to do root choose NO.

Yeah Bad same Problem, turned off and it went on, then again bootloop. But if you press the power button long enough then its completely off. In cyanogen mod i had Problem that i couldnt get into recovery with power button+volume down.
So you should flash kdz, get oneclickroot for LG g2, then autorec lollipop to get recovery. Then flash Rom + gapps + The bumped file.
If you dont know how to flash kdz, you can ask here. I will help
Good luck

Yeah Ok. When I wanted to turn It off, I just pressed the power button until the screen went black and the logo came again but after 2-3 sec the screen went black again, then it was off (just hold power button for 10sec)
Try that when your phone keeps restarting

Get the lg mobile support tool, install it. Then open and connect your phone via download mode, it will find the phone and download the kdz for it. That should work.
If it doesn't install automatically, click on additional options then click on set upgrade error back, or something like that.
Before all that install the driver from
