Hello,

I have a SM-765S (SM-R765SDAASKC). Unfortunately it is bricked, completely stuck in the ODIN mode. In the recovery non of the options are working (except for the power off).
I managed to connect to the pc using a usb cable, but the problem is that the watch not accepting any firmware that is currently available here. ODIN fails with the "complete(write) operation failed" error. If I try to repartition the watch will display the "Secure Check Fail: (PIT)" message.

Probably I need the proper firmware for it but I could not find and similar one, 765A and 765T not working.

Please help how can this be fixed.

Are you from Germany or Korea?


I am from Germany...

Reason for asking is...

I was not really able to detect Firmware Infos about your Device...

If you look at your PHOTO...
You see Bootloader is from:
Code:
SM-R765
not
SM-R765S
This leads to info latest/last FOTA Firmware was:
Code:
R765KOU2BQE2


Btw, do you see in menu also Upload wireless Upload usb ?



We have some similar Problem with SM-R765F... but here it is possible to find Firmware on paid site...

In the recovery Upload and Upload wireless also leads to ODIN downloading mode. The recovery is bricked also.

Maybe the product name shows only the main model number

@szegi2

Try to work together with SM-R765S user...


Maybe we can find working Firmware...


Step 1

Reading PIT (partition table) from device...


With USB cable would be easier...

With Tool Heimdall...

With WiFi I have only idea to sniff ODIN connection

Good question how... ...


I will check on weekend what I have on my HD... SM-R765 related...


So maybe good idea to share infos which Firmware you allready found and Link...

I can only remember ATT... which I have only AP part... not the others...
Full... all files I have only from T-Mobile...

So I have only 1 PIT file... if I remember correct...

Best Regards

To find something about SM-R765S is really hard...

Google search results for today...

Edit 1.
The hardest hard way to get compatible Kernel seems here:
http://opensource.samsung.com/recept...hValue=SM-R765

But if download wireless is alive...
Also Linux Kernel is valid and alive...
Also few other files should be valid... on device...

You can find my PIT file attached.
Heimdall could not read the pit using windows. I installed Ubuntu to an old laptop and it worked
Thx for the links.

Wow... how you made it with WiFi.



I have last time used Heimdall few years ago...
Maybe I am not up2date...

Thanx for PIT.



Compared with SM-R765T from here:
https://forum.xda-developers.com/gea...5-att-t3588066

We can see major differences... and I mean not the additional dumped data...


Attached PIT from:
SM-R765T

I still have no ATT PIT...

@szegi2
If you can help this user to dump PIT from SM-R765F... please.
https://forum.xda-developers.com/gea...rdown-t3659431

Thanx in advance.

I have cut/removed additional data from sm-r765s_readoutfrombricked.zip

Result is attached... usable for ODIN action...

1.
In PIT file you can see which Bootloader "Revision" is active...
Similar to Odin Download Mode Info...

02

Close to last 256 Byte RSA 2048 Signature...

2.
If we compare this PIT dumped from SM-R765S...
with SM-R760... for instance BQC5...

Then 1:1 except the last 256 Byte RSA 2048 Signature...


Best Regards

Edit 1.
SM-R770 PIT too
Again... only RSA 2048 differ... 256 Byte...

Hi,
Flash is failing with the "Complete (Write) operation failed" message
Need the full rom or maybe it needs a re-partition. Unfortunately I get the security check failed (PIT) message when I try to re-partition with the PIT file which was read out from the device.

Please.

Maybe user(s) with alive SM-R765S are here?

Maybe somebody could check with SDB the partition...

Code:
cat /proc/partitions
Then we could compare if this dvice have Original PIT or something is wrong...

Thanx in advance.

Best Regards
