After several attempts with the cable that I made, it has finally worked and has detected a device and I was able to reinstall the system. This time I left it a while so it will charge the battery a bit and then go into odin mode.

Soldered wires?

Or solderless?

Thanx.

[Samsung Galaxy Watch] davigar:
Solderless, I made the same cable that made m0fly92 without disassembling the watch.

I bent the pins to match the contacts and I filed them to leave them all at the same height, just connect it recognized by odin and flashed it without errors

Your text shows Bootloader from SM-R830 is alive... :good:

But now WiFi and normal Booting and so on is block by Knox/Bootloader... :(

It's not that.

I can't figure out a way to make the cable and connector stays stable with the available tools I have currently. :crying:

I'll carry on to explore options but may need to open up the watch eventually. So far it seems a trip point screws. I read that it's similar to Nintendo switch screws.

I'll report back once I've managed to secure the cable and try Odin.

Anyone with any solderless success?

Oh dear oh dear.....

So I made a massive schoolboy error - bought an Active 2 (44mm) watch off eBay. They informed me it was the UK version, it was actually a German version and therefore Samsung Pay wasn't working. Instead of sending it back and getting a replacement etc....I decided to try and fix it myself - flashed the watch using SM-R830 combination and now the device is unusable, stuck, bricked whatever you may call it in ODIN Mode like the rest here.

I know if I send the watch back they will send it to Samsung who will run a diagnostics etc and will determine that someone has attempted to flash it (me). Yes I wish I had returned it now but I am where I am.

I have scrolled through this feed and I appreciate the last few posts were only a month or so ago - I would like to know if anyone has succeeded with a solderless method thus far? I am not entirely sure I trust soldering directly onto the watch itself for myself so I am hoping that somebody here can help???

From what I understand, I may require a THICK micro USB cable to cut, separate the white, black, green and red cables, I might require 2.54mm male female pin header??

I look forward to hearing from you all making fun of me soon *facepalm*

I am not from Germany no apologies. I am from the UK. I sent the device to Samsung directly for repair the day before yesterday. I thought I would chance my arm and see how much they quote. It looks like they have repaired the device according to the email I received today however no discussion on charge etc... So maybe they have miraculously repaired it free of charge! I'll let you all know when I receive the device back
[Samsung Galaxy Watch] vrivotti:
Thanks everyone for the tips. I just recovered my watch without solder or even openning it. A micro USB cable and some tape were all I needed.

Just wanted to share my experience. Hope it helps someone.

I got stucked in Odin Mode after flashed an incorrect firmware on my watch. I have a SM-R820 and flashed it with a firmware for SM-R830.

I didn't want to damage the watch and I didn't have a connector. I also didn't have a screwdriver to open the watch.

I disassembled a micro USB cable and connected the pins from the micro USB port directly to the cables.

I used a lot of tape to isolate the cables.

I also used a lot of tape to join them.

I grabbed the cable with my hand. I ran Odin and everything worked as expected.

Just a note. If you decide to try this, be very careful: you must not touch the pins, the pins must not touch each other and you need to be very still while flashing the watch.

Edit: Look at the images here

How to fix it

!!!!FOR EVERYONE WITH BRICKED WATCHES!!!! [ ODIN MODE STUCK ]

There are 2 ways you can solve this.

1. You have to dissassemble the watch, solder an usb cable to 4 golden debugging contacts on the watch's motherboard, and flash the original firmware for your model. I strongly discourage this option because of the following : 1. You can short circuit your motherboard 2. You will most definetly lose waterproofing 3. I havent found an original firmware yet,but I have found something which i havent tested so idk if it works. Links down below if you want to try

2. You can just go to Samsung Service, as I did, tell them your watch starts in a bizzare odin mode and you dont know what to do to restart it . To make sure they believe you you have to be like the watch bricked itself , also in odin mode you have to have CURRENT BINARY : Samsung official ( or something like that ) and WARRANTY VOID : 0, mine were perfect and repaired my watch in 2 days for 0 money. If your warranty void is 1 or binary is unofficial they ll charge you 20 30 usd i think.

Also if you have found an original firmware or wanna try the firmware i found and are brave enough to DIY it here is a guide on how to do it :

[MENTION=1030585]adfree[/MENTION] I have been following in hope to unbrick my SM-R830, been trying the non-solder option without much luck so far, but thanks for keeping this thread going with new info.

Do you know, my watch doesn't seem to be charging, I put it on the charger and I get about 10 rows in green which says charging then the final line says escape and then shortly after the watch powers off and I can’t turn it on to see the odin screen until its back on the charger.

I’m also thinking, if it isn’t holding a charge then my usb connection is hopeless, any idea?

I didn't use any tricks. The pins were not perfectly aligned, but they were inside the dots and with some pressure I managed to keep them in place while flashing. The most difficult one was the red pin.

Use your finger to keep them still and with the other hand put them in place. I'm sorry, but I don't have a secret recipe.

[MENTION=1030585]adfree[/MENTION] Unfortunately I damaged the board, I tried too much without opening it and scratched away some of the pogo pins from the board, its a mess. I wish I had just opened it in the first place since the pins are much easier to get to then.. Hopefully 6/8 months down the road I can get a cheap motherboard and revive it.
[Samsung Galaxy Watch] wasser79:
In General, everything was solved easier, I went to the Samsung service center and there I was asked for 7 euros. At the same time, they did it without access to the Board, that is, either there is a key combination that activates wifi on the watch or something else.

This is a Great thread going on here, and relates in many ways to my issue,

I purchased a sm-r825F from ebay which turned out to have sm-r-820x live demo loaded,

i have played with odin3 a few times with phones and watches using the direct usb connection, however I didn't want to open up the watch and wanted to try and flash the firmware using netodin3.

i downloaded Netodin3 v1.0 , jump into widi dl mode on the watch, set my watch to ap mode, change my wifi on my laptop to the watch, my watch connects to the laptop, ns displays an ip address, in Netodin3 v1.0 it displays the ip of the watch, i goto my ap bl cp and csc files from version R825FXXU1ASI7 Tizen 4.0.0.6 which acording to Samsung update to the latest

R825FXXU1BTI9

Tizen version : Tizen 5.5.0.1

Release Date : 2020-11-02 which is loaded on a friends watch of the same model from factory,

when i press start the big red box goes to FAIL

what am i doing wrong..... have i missed somthing or does wireless dl not work on this model watch..

$$$$$$$ a few hours more research later, I discovered that the if i am using an md5 file that i only need to use the AP fils since it contains everything else,,,, however,

after successfully reprogramming the watch via wireless with only the AP file i found that the watch still displays LIVE DEMO and only the battery level is displayed, i can get feedback when running my finger around the bezel, and nothing else, but i can still get nack into the dl and dl_wifi menus.... i reflashed the watch 3 more times without any progress.... ideas would be very welcome... thanks
