Do you have any .tpk files? Samsung is shutting down the Galaxy Store for Tizen watches in November 2025 and I'm trying to figure out a way to back up .tpk files of installed apps, or how to recompile them or something.

Maybe in few days I have Gear Wearable for Testing self...

It is not Gear S3... but for beginning broken Gear S2... its cheaper.

Device is Software dead... so I have to find first way to repair it...

I hope it is repairable... :o

I hope no Hardware damage

At the moment only idea, to make "tests" maybe "safer"... to remove sboot.bin and cm.bin from TAR file... BEFORE Flashing with Odin.

NOT tested... only idea... maybe then also dead... :D :rolleyes:

About cm.bin... Crypto Manager... short used Google... leads to this Thread:

I need to charge and hopefully I can flash Firmware to repair it...

I hope...

I was able to see menu... like this:

Select REBOOT MODE
Download
Download (wireless)
Factory command
Recovery
PowerOff

Because first Question...

Factory command

:confused:

What is this?

Menu again?

Shell input?

My Gear S2 reboot...

Edit 1.

Memos to me...

Factory Reset via Recovery should look like this on working Gear S2:

On my not... maybe because battery not charged... Wireless DL Mode I saw Warning Picture... to charge minimum 15 % or something like this...

Later for me... Download Mode...

No idea why... on my Gear S2 I can only see Download instead Download (USB)...

Maybe depend on Bootloader Version...

Found this about Gear S3... menu looks similar to my Gear S2...

Guys, if you are a fan of stock gear S3 frontier watch face and disappointed that there is not moving second hand and useless complication. Check out my watch face which I made using facer app.

It's the stock watchface with moving second hand, working gyroscope light and battery, month and 24 hr clock complication.

It was a good run. Thanks for starting and giving us a better base. Maybe somebody more knowledgeable than I will pick the project back up.
[Samsung Gear S3] Kickasskev:
I'm absolutely gutted, bought this watch thinking it had android wear on it. Once box is opened and watch started its non refundable, £300 down the drain in my eyes. Absolutely nothing to download on Samsung app store other than 15k watch faces pffffftt.......
[Samsung Gear S3] rockz1991:
Not to mention all these watch faces are pricey
[Samsung Gear S3] Kickasskev:
Yep,

This s voice is a joke, can't even ask it to send an SMS.
[Samsung Gear S3] rockz1991:
Well, you need to appreciate a few things in gear S3. First of, the rotating bezel is cool, at least in my opinion. Secondly, when compared to all other flagship smart watches, gear S3 has the best battery life.

At the end of the day, we only want our smart watches to show time, notifications, call, text and other essential features. If people want to use apps, they would prefer a phone over a watch.

I agree, Samsung is too busy promoting stupid tizen instead of Android Wear for their smart watches, but we knew that before purchasing right? Let's just hope that someone out there can port Android Wear soon. Also, try facer. They have enormous collection of free watch faces.

I hope you feel better now.
[Samsung Gear S3] Kickasskev:
Lol there are some good things on it I agree.

It was actually a gift for my birthday I got this, saw it on YouTube and it looked good, mentioned it and 2 days later I had it as a surprise, I never looked into it or what was on it as I never knew I would get it, I did look at other watches but thought the all ran the same software apart for Apple (obviously).

Wish I'd done more digging before I dropped a hint ??
[Samsung Gear S3] speedme:
Android Wear has its flaws too you know.

Each smartwatch OS has positive and negative points.

I just bought my S3 this week, but I'm no stranger with smartwatches.

Owning a Gear 2,which can (and did) run both Tizen and AW, I experienced it myself.

Also had a Moto 360 for several months.

The S3 has been sold a lot, so good chance there will be a lot of skilled devs among them.

Maybe willing to figure out how to port AW to the S3.

Wait, gear S2 had option to dual boot to tizen and Android Wear?
[Samsung Gear S3] speedme:
No, not the S2 (as far as I know)...

I was talking about the Gear 2, which has a square screen and camera.

It was one of the first smartwatches Samsung created.

And it's not dual boot, but either Tizen or AW. It has an AW port, which didn't have all functionality, but the major part worked.

posting to add more interest into this project. i looked around and this really is the best watch out imho except for tizen. im having buyers remorse with the gear app store its just plain ridiculous. The only reason it hasnt gone back yet is because watchmaker is available so i dont have to spend 1-4$ each watchface from samsung. But i cant stand not having all the android apps available on it like my moto 360 did. Maybe we need to start a bounty for this watch.

IMHO this watch would be unstoppable with AW2.0 on it, come on guys lets make this a reality

[MENTION=1030585]adfree[/MENTION] did you find the solution to your frp unlock? Are you able to enter the recovery mode? I am still waiting for my pogo jig GH81-12016M SVC JIG-POGO JIG, hopefully i should get that this week and continue the development furthur. Do you have any tools that I can use with odin to capture the mem dump. Also if you have access to upload mode with your 5 pin custom cable that you are going to make you can mem dump from the watch using specific register addresses. Also make sure when you solder the wire to the pins dont use a soldering agent with impurities as they can kill the ic circuits on board. Also i have noticed a behaviour while holding power key after rebooting press the upper key with the power key and enter the download mode the watch does not restart, i think it just stalls but no way to check coz no jig yet. While flashing sboot.bin cm.bin needs to be flashed inorder for the signature check to be completed. But new patch from samsung does not let you go back to older sboot. There is a problem with that and watch cannot be rooted unless knox is tripped.

It should be a normal connection. It will detect the resistance and current and change the connection to the uart mode. No special drivers needed. Install the Samsung USB drivers for Windows. Make sure Odin version is 3.12 otherwise you will have problem flashing.

Hi there!

I'm new to the Samsung crowd. Got my Gear S3 beginning of the week and will try to help out as much as I can.

Right now I'd prefer not to do anything to the Gear that might brick it, as I lack the Samsung flashing know-how and a proper jig for flashing a bricked device.

[MENTION=1030585]adfree[/MENTION]: you seem to be on that topic right now. Let us know if you have a stable solution. I'll talk to a few HW colleagues at my job, for additioinal ideas. Some of them have already built in circuit flashing equipment. So maybe they have an idea.

thats good. are you going dump any memory for debugging ?
[Samsung Gear S3] adfree:
Not yet...

But I have now time to do stupid things.

My plans for today... or for next 2 days... depend where next problem occur...

1.

root of all costs... :D

Without Root this Gear Wearable su ..x x s

Generally without Root... Tizen is very boring...

1.1.

My last attempt before I was sleeping...

Tried to flash again same Combination Firmware...

But this time attempt failed...

[COLOR="Red"][B]Invalid Signature: PIT[/B][/COLOR]

PIT file is same but last Bytes are different.. damn RSA 2048 crap

2.

If Root is done...

No idea if then my Root or I am able to manage run Combination Firmware...

Then I will perform few dd dump stuff...

3.

If I survive Rooting and enough time...

Then I will check Upload Funktion...

Then I am able to tell which RDX Version I have maybe work...

Otherwise maybe we can find newer Version...

4.

I have plans with Certificates... but depend from success Rooting...

5.

If Root is stable... then I can remove/desolder wires and close Wearable...

Then I hope...

I can play little bit without killing again.... :D :o

So my timetable is MAXIMUM 1 week = 7 days... before I use again Y Screwdriver to close Backplate...

I have only 1 device... and with soldered wires it is really hard/risky/dangerous to move...

Press Buttons etc...

Good news is. Charging is possible with USB cable... :good:

So I don't need the Charger for now.

Please look into this post...

Maybe later I will do Photo... if I have time for this... hold Cam + hold my wired construct +

Anyway...

Reactivation Lock is "part" of Security concept... maybe we coul say it is part of Knox...

But for sure it is Bootloader Security crap = inside sboot.bin

Bootloader (sboot.bin) reads from "somewhere" in the eMMC...

"I am Locked" to prevent Custom Binaries/Firmware/Modification...

Files are signed... so somewhere is Signature...

We can not sign self... as RSA 2048 (I think)...

So "we need" to disable Signature check...

At the moment I have NO idea if this require mandatory special sboot.bin...

Or commercial sboot.bin can handle Custom and Offical Binaries...

So "we" have to find sboot.bin which fullfill our needs...

Or we can find little tiny Security hole...

Maybe Signature check not happens... if I dd partition... who knows...

Will try later to write via dd Command the rootfs partition...

I have to study my old Threads...

GT-I9300 related... where I have found way to kick off sboot.bin...

If I remember correct... I have found also location for Security data... for GT-I9300 GT-I9305 and was able to erase them... :D

Warranty Void etc...

Long time ago...

I do such things not every day... and I am old man...

Nitay has found a vulnerability in the sboot. maybe watch one of his video i dont have the resistor and the modified usb cable to enter the secret mode via odin.

how watch fits.
[Samsung Gear S3] SgtSeppel:
[MENTION=1722345]tids2k[/MENTION], where did you get this usb jig from? I was looking around using the part numbers from the Samsung service documents, but couldnt find it?

I know the circuit is pretty trivial but the casing seems to help with proper positioning and holding of the device.
[Samsung Gear S3] SgtSeppel:
I had a quick look at the video. Very interesting. The fact that the anyway jig is mentioned/used in the service manuals for the S3, at least hints that the serial interfaces are also available.
[Samsung Gear S3] tids2k:
Anyway jig is only to change the current on the resistor to enter into the secret mode. As you see Nitay mentioned that its better to use own usb cable and increase/decrease the resistor current to achieve the required mode. I also think that there is a hidden jtag servicing mode hidden somewhere in the sboot which nitay has mentioned as well in the video. Your answer to your previous question lies in post #73

serial interface as you mentioned are definately available. but we need a special micro usb to serial connector, remember the profilic usb 7 pin connector for flashing nokia n95 ... and so on -) lots of detail at gsmhosting if you search. also [MENTION=1030585]adfree[/MENTION] i was going through your 2013 posts , will bterm still work for the upload mode. is it still dependent on amss protocol ?
[Samsung Gear S3] SgtSeppel:
Yes, I was only referring to the implications. A diy cable would certainly be the way to go since the samsung jig does not seem to be for sale. They use all kinds of tools for device configuration with the anyway connected. I wonder wheter they use some WriteMemoryByAddress mechanism or if they have a separate resistance/mode for these tools.

Would be interesting to see some more detailed documentation about the Exynos 7270. I'm wondering how that would be implemented. I doubt that the CPU has an onboard debugger connected to the USB. Anything outside of the CPU would be too expensive for mass production. This would only leave a direct JTAG connection via the POGO interface. I just dont see the usecase for keeping JTAG in a production device. I would assume that there is only a JTAG via test points.

Maybe the ID on the switch refers to the USB ID line as mentioned in the video. Can you post a picture of the underside of the small PCB?
[Samsung Gear S3] tids2k:
chip debugging can be achieved by connecting the jtag points to the chip connectors measuring the current and then finding out the resistance on each connector. pogo pins we can not use for jtag only for uart and mem dump. The documentation for Exynos chipset is internal reference document not available to the masses. Even the development boards with exynos does not have any documents referring to the chipset itself. My best bet would be to contact E.V.A here as he might have a copy of the chipset. Anyways I am stuck at opening the system.img as the first 100 bytes doesnt match the usual android structure so no kitchen is accepting it to decompile. Throw me some light. My Y screw driver is lost and I wont have time to go and purchase until friday.

1.

Combination Firmware which is possible to flash...

Need output from this command, to prevent mistake if rootfs.img not in p12...

cat /proc/partitions
