But BEFORE... try to click the 2 Buttons in diiferent combinations...

Idea 1...
https://xdaforums.com/showpost.php?p=71822126&postcount=66
Try after start Download(Wiriless) mode hold power button 2-3 seconds. After 1 seconds try again - hold 2-3 seconds.

Yesterday i unbrick my forntier with same problem.


Idea 2.
Someone wrote me in PM...
about successfully flashing Combination file... start yes... BUT... WiFi option for Odin was missing or not working...
I still press power 5 time and inter download wireless and flash rom but he not open directly and now he till me kernal panic upload mode i can inter download wireless


I mean "we" have only 2 Hardware Keys... maybe different Click combinations... or hold "Codes" possible...

Maybe try to enter Recovery and try to Factory Reset... if possible.

WARNING!
Own risk.
I have no idea if Factory Reset in Combination file do more as from normal Firmware known...

Best Regards

Caution!

Combination Firmware is not what you are searching for...

Could create more trouble...


You need to find:
1.
Reason why you lost your Language...

If official FOTA Update then...
A.
Something goes wrong...
B.
No spanish inside or Mistake...

2.
You need Firmware update... BUT you need correct Firmware...

3.
Safest way would be Service Center...

Only if you have Odin experiences... and CORRECT Firmware package... try at home.

those text are constant that take something app call their callback func.
so now you are getting an error it means that app cant connect to sensor maybe ...
if you want to find out why is that happening you need LOG file
you can get that using tizen studio or SDB...

Good luck:)

My own test with my own SM-R760...
Reactivation Lock = OFF
no idea if other sideffects possible if RL on...


BQC5 on device... successfully flashed with WiFi. :good:

Then later I was able to flash BQH1 over WiFi...

Later I will check if I can flash BQC2 from BQH1...

Only as info... for me.


Flashing with netOdin over WiFi take around 15 minutes...

Best Regards

Edit 1.
After 1 attempt with modifying rootfs.img... which fails... :rolleyes:
I was able to enter Download wireless to flash again BQC2 from "corrupted" BQH1.

In worst case scenario... This post is very usefull:

:good:

If you have the same problems with your (bricked) S3 then go to download wirelessly mode en as soon as you see the flower then push the power button 2 seconds en let it go for 1 second, than push it again for 2 seconds en let it go for one and so on til you get him in to download wirelessly mode. May take some attempts but it saves my ass a few times.

BIG thanx to BokkieAndijk
:cool:

I saw something like this also... in my Adventures with trying downgrade...


In theory you have now same problem...
Download wireless not boot stable... only black sceen...

Look at this:
If you have the same problems with your (bricked) S3 then go to download wirelessly mode en as soon as you see the flower then push the power button 2 seconds en let it go for 1 second, than push it again for 2 seconds en let it go for one and so on til you get him in to download wirelessly mode. May take some attempts but it saves my ass a few times.

In other words... hold Power Key for 2 seconds... release Key... Hold, Release...
Its question of timing...

And you have Download wireless back. :angel:

Then you can try again.

If not work...
Please check menu Download...
If Reactivation Lock is ON or OFF...

Depend how urgent... or maybe you can wait.


1.
Attached is Photo of my SM-R760...
Photo taken before you post your problem...

I thought Ithis is Security trap... as I have tried to downgrade to older Combination Firmware... :D
From 2BQC2 to 1AQF1 or 3 or something like this...

Here Rollback Prevention...

2.
But maybe this is something else... not Security related but maybe some Network conflict... transfer trouble...
:confused: :confused:

So do you ever before succesffuly flashed via netOdin?
Maybe to BQC5 or BQH1?
Or is this your first time attempt?

3.
You saw same Error message?
Or something else in red?

Maybe try first flash BQH1 fully, then jump to Combination Firmware...

Again. Depend on you... if it is "urgent" or you are lucky nothing explode and your S3 is alive... :D


I will try to search in Firmware... maybe then I can restore the whole Error message...

Best Regards

    Does Samsung Pay now work for you?

    Also, when flashing the combination firmware, does this go in the "BL", "AP", "CP" or "CSC" parts of NetOdin3?

    Use "AP"!

    An Yes, SPay is working now here in Brazil, after CSC change to ZTO (Brazil).

    Please, need info/confirmation.
    If Combination Firmware writes older sboot Bootloader aka downgrade...

    This should be possible to test with SDB and this Command:
    Code:
    cat /proc/cmdline

    Thanx in advance.

    Best Regards

    Looks 1:1 same like mine SM-R760

    Under BUILD VERSION... you see Bootloader (sboot.bin) Version:
    Code:
    R760XXE2BQC4

    This is exact the Version from BQC2 Combination package...

    If this Screen is visible... and you see R760XXE2BQC4 still in all Stock Firmware Flashing attempts...
    Then sboot.bin is write protected... NO idea why and how to unlock it...

    If BQC5 or CQK3 work, then accept this as workaround...

    FOTA mechanism is disabled... because WRONG Bootloader...

    Sorry.

    No idea if this happens as you reanimate device via USB...

    Best Regards
