[T-Mobile Samsung Galaxy Note 3] daCADman:
Hey Guys,

I've just rooted (only rooted, haven't flashed anything yet) my Galaxy Note 3 sm-N900T from TMobile (running android 5.0). I bought my unlock code online and unlocked it and put in my Cricket Wireless sim. It works, calls, messages etc. however, I have this little red phone icon to the left of the status bar that says "WiFi Calling Error. ER05 invalid sim". Also on WiFi I can browse, like the Playstore, for instance. But when I turn off the WiFi and try to use my data plan I get no Playstore, no browsing at all. I get messages like 'not connected to the internet' or 'no internet connection'. Has anyone dealt with this before? Or can someone please point me in the right direction to try and resolve these issues?

Hi all,

I've received my S7 Edge today(Exynos), yay.

All was working flawlessly until few moments ago, I was running 3Dmark, and before I even start to bench, while i was downloading the first scene The screen goes all black, then after 10 seconds, there's a message on top (in the same way a rooted phone would display "kernel is not seandroid enforced..."):

Bootloader Exception

[RST_START = 0x100000000 ]

[...]

Exception: do_handler_serror: SERROR(esr: 0xbf00000000)

[...]

I didn't install any rom, root or else, it's pure stock untouched. I tried to reboot phone using volume down+power, it reboots I think (screen goes all black) but quickly the same message appears... :(

I'm surely going to call phone operator to tell them that phone is KO, but if one of you guys has any idea that would avoid me to send back phone to warranty, it would be nice :)

Thanks !

[Samsung Galaxy S7 Edge Questions and Answers] CuBz90:
I'd suggest a factory reset if the above fails.

Hold Power + Volume Up + Menu

Then use the volume keys to scroll to factory reset and select using menu or power buttons.
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
Hi guys,

Thanks very much for you answers,

Unfortunately any key combination is not working can't get into recovery nor download mode ...

I don't want to try Odin, scared about potential warranty issues ... but it kills me to have to send the phone back to sammy and wait .. :(
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
The phone must be off for the Volume Up + Power + Home button combination to work. Keep those pressed for like 10 seconds, even after the phone powers on. I just tried it on my S7 Edge (which drops every call) and could restore to factory settings (but didn't solve the issue).
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
Thanks for your advices !

Unfortunately, even with this combination and a lot of patience I cannot manage to "bypass" this Bootloader error ... :(

I'm mad because it will take one month to get a new phone from my operator(just called them ...)

So maybe i'm going to try Odin ... but if I cannot put my phone into download mode, i'm f*ckued, right ?

Here's a photo of the error message :

I'm stumped. I've never seen that before
[Samsung Galaxy S7 Edge Questions and Answers] thunderroid:
From where did you order your phone?
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
A french mobile operator , Bouygues Telecom.
[Samsung Galaxy S7 Edge Questions and Answers] thunderroid:
Can you do a factory reset from the Settings menu?
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
Nope, the phone doesn't boot anymore... it only displays the bootloader error message...

And no possibility to access reboot or recovery... :(

Maybe I can try to check with ADB, but my problem is that i would need to active USB debugging in settings ... but i can't do that :(
[Samsung Galaxy S7 Edge Questions and Answers] hiepgia:
Return it. Nand flash died.
[Samsung Galaxy S7 Edge Questions and Answers] thunderroid:
Yap, I think you have to return it.
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
Yep, I wanted to avoid it, but I don't see other reasonnable option. The phone didn't last more than 24h ... ok, it happens, I know ...

My previous (Still actual (sic)) Phone was a Note 3 and I installed so much roms, soft bricked the device so many times, but I could always restore it ... But not the S7 EDGE ... And I didn't spot any other user with same bootloader issue...

I've just sent back the phone for replacement, Thanks for all who replied to me in this thread :)

Oh and by the way : don't download 3DMark from play store , it will Hard brick your phone !!! (haha just kidding , i know it's not what caused my phone to die, I'm sure of it , however I won't try to install it anymore i think^^ )

Cheers XDA crew !!
[Samsung Galaxy S7 Edge Questions and Answers] Borgella:
Mine has done just the same. went to bed, woke up this morning and the same message as yourself.
[Samsung Galaxy S7 Edge Questions and Answers] Mr_PoPoP:
Sorry to hear that bro :(

Try things to troubleshoot if you wanna, but my advice : don't lose one day of trying to fix it, send it back directly to warranty...

I tried lot of things, key combination to reboot phone in recovery or download, I tried Kies, Odin, ADB....

I believe it's a real samsung bug that will happen to many people, So send it now before sammy is drowned under hard bricked S7 phones and start to have issues to provide replacement devices....
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
the S7 edge is getting a "urgent" update on approx 3mb..maybe this is a fix of some sort.
[Samsung Galaxy S7 Edge Questions and Answers] CuBz90:
That is to correct the Screen Edge sensitivity
[Samsung Galaxy S7 Edge Questions and Answers] aramisathei:
For anyone else who runs into this issue, I managed to fix my phone.

Holding the power and VOL down buttons for about 5-10 seconds will reboot the phone; if you hold home at the same time you can get into download mode (might take a couple tries).

From there, you can flash a new bootloader (BL option in odin) and then get back into recovery to do whatever you need to do.

Went from soft-brick to full restore in about ten minutes--not even a factory reset necessary.

Hope this helps!

I had the exact same issue on my S7 G930F this morning after flashing TWRP 3.0.1-0 over TWRP 3.0.0.3 with TWRP image function. Yes, I’m 100% sure that I did not accidentally pressed flash bootloader instead of recovery.

No chance so fix the "Bootloader Exception" problem with standard methods (bootloader mode not possible, recovery not possible, safe mode not possible, power button for 30 seconds no effect, etc.).

There were some strange characters at the end of the Bootloader Exception screen like it’s a timing problem or something which interrupts the BL process… Its very similar to the pictures posted by Mr_PoPoP.

One hour later after probably 100 attempts (yes, I was desperate!) the download mode showed up and I was able to flash the recovery (TWRP 3.0.1-0). Since then device works well (did TWRP backup, Titanium backup, rebooted several times). Absolutely no datao lost...

I’m on G930FXXU1APC8

Never had such a strange issue in the past with all my Samsung devices…
[Samsung Galaxy S7 Edge Questions and Answers] mathieulh:
This is likely due to eMMC hardware failure. You got unlucky I guess.

[Samsung Galaxy S7 Edge Questions and Answers] bossarts:
eMMC hardware failure sounds bad.

My S7 works without problem since then.

Are there any possibilities to ckeck or scan eMMC?

Is there any log function which could confirm the hypotesis of bad eMMC or something like a SMART function?

I have exactly the same issue on my Italian Samsung Galaxy S7 Edge, before that i have had sporadic freeze but now is totally dead. How you did exactly to boot into recovery?
[Samsung Galaxy S7 Edge Questions and Answers] bossarts:
I had one freeze which was not right before the Bootloader Exception (some weeks before).

As I wrote I tried to access Download Mode and Recovery mode during 1h with the key press combination as usual. I always landed in the Bootloader Exception error independent which key press combination I used. Phone just rebooted and went into the error. I probably repeated it 100 times. After this I have put my phone on the table (with error showing), drank a beer :D and 15 minutes later I pressed key combination for download mode which was working as usual. :good:

I flashed TWRP 3.0.1-0 with Odin, phone rebooted and voilà it works. Since then never got any problem... :highfive:

Really strange behavior. Since then I make daily TWRP backup. :fingers-crossed:
[Samsung Galaxy S7 Edge Questions and Answers] neogen96:
No way, i tried for hours but i can't access download mode. I've just sent back the phone for replacement. :(

Same problem for me :

I was playing with my new Gear VR, let my phone alone and when I go back : black screen with blue led (no responding).

After reboot : bootloop and now "Bootloader exception"...

No way to boot in Download mode :-/
[Samsung Galaxy S7 Edge Questions and Answers] cwmdu86:
Also had this Bootloader Exception problem over a week ago. Sent my S7 Edge back and it was 'repaired'. Although less than a week later the screen is now showing strange patterns, lines and blocks of colour on it and it has had to go back for another repair.
[Samsung Galaxy S7 Edge Questions and Answers] killtoo:
Motherboard changed by Samsung.
[Samsung Galaxy S7 Edge Questions and Answers] adrscu:
Later edit: I've put my broken phone through a local authorized samsung service center

They've replaced the mainboard.

------------------------------

I've got this dreaded error myself today on my s7e.

So the general conclusion is that it's a hardware fault?

Is there any point for me to Odin stock image to try to revive it, or just send it back to Samsung to get it fixed?

I'm a little skeptical as to sending it for repair. I've heard a case where someone sent their s7e in for some repairs under warranty, and they haven't glued it back together properly. The phone was not watertight and after he submerged it in water, it stopped working, of course. And now they're denying any warranty claim because of water damage..

Sure as hell don't want that to happen to me..
[Samsung Galaxy S7 Edge Questions and Answers] muhmtt:
1.finish the phone's battery completely dead

2.connect to the computer

3.start in download mode (3 button volume down + menu button + power)

[Samsung Galaxy S7 Edge Questions and Answers] Kitodama:
I could get to download mode you need to:

1) Press Volume down button + Home + Power until the screen goes off

2) When that happens quickly move your finger from Volume down to volume up (before the Samsung logo appears)

3) You are now on recovery mode

4) Select power down

5) As soon as the screen goes of press the Download Mode keys

6)Profit, at least it was in my case.

Hope it works for you and you dont need to send the phone to SAT.

-------edit-------

Once I got in download mode I used Smart Switch to hard reset the phone. Now it works perfectly.
[Samsung Galaxy S7 Edge Questions and Answers] AlexBlueFlamez:
My device has done the same thing but with a different error message: I NEED HELP PLEASE, IF YOU WANT I'LL PAY . So i tried to root my s7 edge following the exact same steps in the video. when i got to odin and it said pass, my device went to a screen that says: Bootloader Exception

(the error message would not show because the website was blocking it for some reason but it was similar to MrPoPops's error message and the same thing happens: cant go into download mode, cant turn it off,on and same exactly the same thing as MrPoPops happens to me)

I have tried all button combination and when my device starts it says up in the left corner: Kernel is not Seandroid Enforcing and goes alsmost instantlly into the screen with the info above ^^^

also my device wont go into download mode, when i try it will start booting again and says Kernel is not Seandroid Enforcing again and goes back into that screen... stuck.

I have tried alot of things and i cannot fix it... if someone could provide me with some help and if it worked i would pay up to 10$ with paypal. Keep in mind i cant go into download mode and when my device was open i had turned on usb debugging and something that said samsung safety disabled or something like that.

Please help someone because i went through alot of work to get my phone and it's sort of bricked now :(

connect phone to pc running samsung smart switch n try putting phone into download mode by pressing the volume down and power button
[Samsung Galaxy S7 Edge Questions and Answers] ates1:
Hi guys i had the same issues with bootloader exception.

after many tries of holding power + vol down + home buttons down did not help.

but i figured out that you can hold down these 3 buttons and wait until the phone is in exception screen DONT REMOVE YOUR FINGERS FROM THE BUTTONS and wait 15 seconds it will automatically boot in download mode.

It worked for me give it a try guys and let me know if it works for you guys;)
[Samsung Galaxy S7 Edge Questions and Answers] Yoguslayer:
THIS exactly. Although it lasted a little longer for me, so don't despair. Also, I tried to still use Odin to flash a new recovery even while I know it wouldn't do crap because of the status of the phone. Tried it anyway and made Odin attempt to link up with the phone. After "Setup Connection" I unplugged it from my PC and continued to try the button combination just as [MENTION=7599200]ates1[/MENTION] said: didn't stop pressing the buttons. It drove me through nearly 3-4 loops of "Bootloader Exception" and then BOOM: Download mode appeared.

After that, I didn't take any more chances and clicked VOL + to accept a new download, and immediately started the process in OP: http://xdaforums.com/s7-edge/development/recovery-official-twrp-hero2lte-3-0-0-0-t3334084

My route was (after having Odin already running): download latest TWRP .tar, Install it via Odin EXACTLY as it says in the post and then reaffirmed the root process WITHOUT going through the Internal SD wipe. I just downloaded Super SU, transferred it to the phone via MTP and flashed away using my newly Installed recovery. That was it! My S7 Edge returned from its slumber to my hands once again (I seem to have bad luck with my Galaxies since the S3, so I've ran through similar stuff in the past). Just don't despair, there might still be a way. After this, I'm seriously considering the chance of a Custom ROM install and TWRP backups every 3 days at least. Time will tell.

TL;DR: Don't stop pressing the button combo for Download mode. It might still appear. If it does, then just follow the above link's OP instructions as if you were to install the Recovery for the first time and you're good to go.

Hope this helps! I actually went like crazy trying to solve the same problem and spent a LOT of time going through xda and Google to figure this one out. As soon as my phone came to life, I started writing this.

Cheers. :)

[Samsung Galaxy S7 Edge Questions and Answers] ZURPLEPERG:
This worked. I now have TWRP. However it's still not booting. I still get Bootloader Exception and have no idea what to do :(
[Samsung Galaxy S7 Edge Questions and Answers] Yoguslayer:
At this point, in my experience with past Galaxy S devices, I would go for a custom ROM.

Normally, they should come pre-rooted and give you a one-time chance to boot your phone again, in which case you may be able to bypass the "Exception" stuff and enter into download mode directly by using the reboot function in the custom ROM and then you proceed to flash the bootloader and modem to the latest version. Chances are you got there mostly because of a ROOT attempt to your phone, so KNOX has already been tripped and you already didn't care about the count going up. Another flash won't drive you crazy, lol.

The steps would be (if your device didn't truly come back to life and stuck to the Exception bug):

- Boot into TWRP

- Use the MTP mode to transfer and backup everything you have on your internal SD (media, mostly). Personally, I wouldn't try to save any apps in this case.

- Now use MTP to transfer the Custom ROM file to your SD (external)

- Flash the ROM (Clean install, so you have to wipe cache, dalvik and data. Technically, almost everything but your External SD. I do this 3 times or 4 because OCD)

- After flashing, it should try to boot and most probably succeed in doing so. Now reboot to Download mode with the extended menu (the power button one) or some app with ROOT permissions that has this function in it.

- If you got to download mode, then flash your new bootloader and modem away!

- That's it. You might also need to get a compatible ROM for the bootloader, but it's a little easier to find one since you can also look for a completely stock build. In my case, I went for SuperMan-ROM, which comes with a bootloader and modem that work perfectly with it. So much for the stock experience delight for me, lmao.

Hope this helps, and sorry for the late response. :P

would a usb jig work to get into download mode because read that the usb jig for s2 works for the s7

---------- Post added at 04:34 PM ---------- Previous post was at 04:22 PM ----------

because if u guys earlier are saying that u can jus keep pressing those button combos that i tried about a million times and still nothing then a usb jig shud work to force the phone into download mode....not so? Instead of driving myself mad trying those buttons over and over again.
[Samsung Galaxy S7 Edge Questions and Answers] Covert_Death:
alright i need help here. same message as everyone else. so far i've tried:

1. holding vol - / PWR / HOME

2. the above button combination but maintain holding it after bootloader exception for a full minute (it never reboots more than the first time and just stays on exception screen).

3. vol - / PWR and quickly switching to vol + / HOME / PWR as soon as the screen went black

nothing works, i'm stumped. this sucks. For me this is an intn'l device and since i'm in the US i don't get a warranty.
[Samsung Galaxy S7 Edge Questions and Answers] zan5hin:
I work up this morning and this has happened to me as well. Phone was working fine, this is my first Samsung (and bloody expensive) so it has never even taken a sideways glance towards a custom ROM or even download any cracked APKs or dodgy apps. I'm really disappointed as not being without a phone for a week while they fix this is really inconvenient as I have to go buy a spare phone because I lost the Nexus 5 I was running before.
[Samsung Galaxy S7 Edge Questions and Answers] Covert_Death:
I assume you have the US version? I'm struggling to find anyone who will even quote me for a repair due to having the international version but being located in the US.

I've been facing a similar problem no 3rd party software as such installed on the phone, completely untouched stock android. I got the same issue when the phone was connected to the power socket, charging. Would like to get an estimate of the number of people who faced this problem when their phone was connected to the charging socket and was actively charging.

did you fix it or did u get a new phone??? the same happened to me :/
[Samsung Galaxy S7 Edge Questions and Answers] tmorterlaing:
Same here. I'd love to know what actually causes this - mine did it very randomly. My phone WAS rooted with a custom ROM, but Ive never seen a phone so completely buggered - the worst Ive seen before know is a Huawei I had to completely repartition- but still doable. This is completely non-accessible, I cant even get past the crazy writing screen D:

How does this happen? What causes it? Should we not root our Samsung S7 Edge devices until we know more?
[Samsung Galaxy S7 Edge Questions and Answers] Tungsten c:
Google sign in

I don’t know if this is related to the same issue but I got the S7 when thru initial setup everything good. Finished my initial setup and immediately told me was executing and update. Phone reboot told me a reboot was done had to sign in to google account, did that and the phone keep telling me the gmail account was different than the one used to sign in.

BS mean while I am getting emails on my laptop that an S7 sign into my account. After lots of trying and sprint store returned the phone.

I was able to get back in it once but when I reboot I had the same problem. Returned the phone

Anyone with the same problem
[Samsung Galaxy S7 Edge Questions and Answers] tmorterlaing:

[Samsung Galaxy S7 Edge Questions and Answers] TomTomcrafter001:
Since it happens also with (I guess) non-rooted phones I wouldn't consider roooting to be the issue.

Does anyone had this without rooting? This would indicate that there must be another problem...

[Samsung Galaxy S7 Edge Questions and Answers] emperor4her:
i had this problem today, and still trying to get to download.. no luck yet.

if i send to service, will they see its rooted? i mean is it on warranty?
[Samsung Galaxy S7 Edge Questions and Answers] TomTomcrafter001:
If the knox thing is tripped, they can see that. And when the flash counter (knox) is tripped you lost your warranty, i think. I don't know how much it costs but it won't be covered by your warranty.

Fingers crossed you get a working device with all your data back. ;)
[Samsung Galaxy S7 Edge Questions and Answers] emperor4her:
well after 100 or more tries with combo i managed to get to download mode.. right now i am flashing stock, i hope it ends up with a "pass".

i was asking about knox, because the knox tripping i think has to do with motherboard. if they cant enter download how will they see the knox trip?
[Samsung Galaxy S7 Edge Questions and Answers] TomTomcrafter001:
Hmm. Don't know :)

But let's hope you manage to restore your device :good:
