Memo to me...

Code:
freshul:/ $ su
freshul:/ # cd /efs/imei
freshul:/efs/imei # ls -a1l
total 32
drwxrwxr-x  2 root   radio  4096 2021-11-21 06:38 .

DBTfreshul:/efs/imei # cat mps_code.dat
XSAfreshul:/efs/imei # cat omcnw_code.dat
XSAfreshul:/efs/imei # cat prodcode.dat

Will try to simplify for me...

Code:
D:\Android\ADBnew>adb push mps_code.dat /sdcard
mps_code.dat: 1 file pushed, 0 skipped. 0.0 MB/s (3 bytes in 0.008s)

D:\Android\ADBnew>adb shell
freshul:/ $ su
freshul:/ # cd /sdcard
freshul:/sdcard # cp mps_code.dat /efs/imei


I hope 1 file is enough for CSC change...

Edit 1.

After Command chinese Language is visable as I set TGY for Hong Kong...
But still XSA und Software...
Then I did FAC Reset... in Standalone Mode I see now TGY is fully set...

Flashing now AUGF OLB again to undo Root... and be ready for FOTA update...

I will try to downgrade with netOdin back to EVB4:
Code:
smR860_EVB4_OXM_v1.tar

Reason:

I will check if Downgrade drip Knox...

For now on GVI3:
Code:
D:\Android\ADB>adb shell getprop ro.boot.warranty_bit
0

I am charging Battery from 70 % to full...

Later result...

Best Regards

Saw this in Tizen time... but not with GW4... first time...

Now I have only 40 % battery left...
GW4 seems not to charge in Download Wireless Mode like Tizen Watches...

I need "only" to flash super.img...

Lets count how many attempts I need...

Edit 2.
Few attempts later...
Restarted my Notebook... hope this time more luck

Edit 3.
Boah I ha..e

This not happen with SM-R870 nor SM-R875F...

Maybe last attempt as only 24 % Battery left...
netOdin work since 20 minutes...
F%&ing progress bar less 50 %


Edit 4.
F%&... 19 % left.

I was able to do FAC Reset in Recovery... now on Charger...
netOdin started...

Edit 5.

Boah ...
Maybe I found way to charge battery...

In DL Wireless Mode...

After Warning to charge minimum to 15 %... I was on 11 %...

I pressed Power Button twice... like for AP Mode...
Now I see in ( DN_Err) but battery is now at 15 %...

No idea if good for display... as Display is full on...

But I will wait for 100 % battery charge before I remove from Charger and try again on other Notebook...

Edit 6.
This is absolute horror...

I can charge 15 % battery in Download Wireless... then I can double press Power Button... for AP connection to netOdin...

Still fail... but more then 15 % battery charge not possible...

AAAAAAAAAAAAAAAAAARGHHHHHhhhhhhhhhhhh....

Edit 7.

Maybe my fault is Notebooks nearly full... not enough space maybe...

Deleted few files... now 12 GB free...

Edit 8.

25 minutes... 1 % battery left...

progressbar less 50 %...

Something is wrong with this sh it WiFi from SM-R860...
Or my old WiFi crap in my old Notebooks

Tested with this old USB WiFi...

Progressbar this time more then 50 % and I was really close... before power down...

Hmmmmm... 1 choice is to find faster WiFi Hardware...

Or I am downgrade from halfdead EVB4... to AUGJ...

Here super.img is 200 MB smaller...

"Funny"...

Charging seems possible but not to 100 %...

Tiny summary...

SM-R860 EVB4 shows something with Charge battery up 15 % in WL DL Mode...
But it really charge to 15 % so you have chance to use netOdin again for 30 Minutes...

My old 300 Mbit WiFi Dongle seems too slow to flash whole 4000 MB super.img

AUGJ shows to charge minimum 20 % battery to use WL DL...

Juhu... 5 % more...

But f&%ing tiny b not charge anymore... to reach 15 % nor 20 %...

It seems only to charge 4 % to land in Odin Mode...

Both AUGJ and EVB4 shows this Picture... found in RAMDISK of Recovery...

I ever looked how much time needed... before...
IMHO 45 minutes or something like this... for all files at once.

Again. Never had problems with SM-R870 nor SM-R875F...
Only my dam. SM-R860 has problem with my old NotebookS WiFi Hardware...

Only as info...

Will try to collect infos... how much time others need for full flash with netOdin...

But 15 % Battery is really Frechheit...

My Tizen Smartwatches charged in Wireless Download up to 100 %...
Without such stupid Restriction...

Best Regards

Edit 1.
According to this Video...

Seems possible to flash whole 4500 MB in 20 minutes...

He started with 33 % battery...

Need help to collect Info(s) about WiFi speed...

IMHO we can see "Link speed"...

Here I see

65 Mbps in 2,4 GHz Network...

I have 54 Mbps... need to check again...


Samsung s h iii RTL work since dayS not... GW4
Also they are not able to add GW5...

Tizen Watches work on RTL... so not my Config Error...

Samsung Support is unterirdisch

Best Regards

Edit 1.

On my SM-R875F I see 72 Mbps... GVH1

Also 2,4 GHz Network

Edit 2.

Okidoki. So I am maybe not alone with no WiFi 6...


Close to 6 minutes I see 65 Mbps

Edit 3.

Low Signal Quality also decrease speed...

Scheduled Maintenance - Remote Test Lab service will be undergoing scheduled maintenance on November 16, 2022, 06:00 AM UTC for approximately 4 hours. We apologize for a

Maybe they are able to fix broken GW4... and MAYBE they have 1 or 2 GW5...

But IMHO we know what will happen...

Seems they were able to remove Tizen devices... so IMHO place for GW4 and GW5 deviceS...

Hmmmm... still strange.

I thought we have "modern" WiFi 4 or something like this...
Code:
Bluetooth® 5.0, Wi-Fi 802.11 a/b/g/n 2.4+5GHz,

I thought we have 802.11n

Maybe we have only 1 Antenna... ?

On Samsungs RTL I see exact this what I see on my GW4...

Code:
72Mbps


Really strange... my more "modern" SM-A202F shows also 72...

But my old SM-G920F shows 144...

So IMHO 2 AntennaS inside... I think...


Hmmmmmmmmm...
?

Spend few hours with my old crap... because the 300 USB Argh...

Good I found solution to enter RTL again... before my Hardware learn fly... against the wall.
:geek:

Best Regards

Edit 1.

Looks really SM-G920F have 2 Antenna:

I will check Service Manuals...

Friendly user with dead SM-R870...

Dead by Firmware Version GVI3
GVK4
maybe creates same trouble if out of luck...

A

He soldered wires to have USB cable connection.


No luck

my problem now is, when i connect to pc it appear connect in COM 4, but automatically disconnects


B

He measured Byttery:

3.91 Volt.

First I thought too low...

He charged externaly... manually... Result:
4.38 Volt


Maximum on battery readable:
4.47 Volt

No luck, still Loop

C

After some Videos and Screenshots...

We realized it is something Serial... unknow at the moment...

So IMHO I think Samsung Bootloader sboot.bin is erased...


Code:
VID_04E8&PID_1100&MI_00


D

Only as info.

My alive SM-R875F connects in DL Mode and Upload Mode (RDX Tool) to same Driver:


Code:
Samsung Mobile USB Modem

USB\VID_04E8&PID_685D&REV_021;&Modem

Only as info.

Maybe we can find what kind of Driver is requested...

Best Regards

Edit 1.

Added old PDF how I repaired my SM-R760 aka Gear S3 long time ago...
With "Exynos" Driver...
Only as example...

Hi, first post in a while.
All I need to know is how to safely revert my Galaxy Watch 5 Pro to previous AVI4 version from current AVK6. I've done this multiple times on the phone and personally never update my phone, my windows pc or pretty much anything in the past 2 years since Samsung, Microsoft etc pretty much always take away features instead of adding them since they already have everything ahead of Apple and now the only thing left is to add this bit of so-called security by trimming and locking down their software these days.

Anyways, I might have been out of my mind to update to latest wear os version on my Watch 5 Pro thinking it would enable the new temperature sensor drivers but instead it secretly got rid of my custom ringtones on my watch. Now that's no biggie since a few adb commands is all it took to re-enable them. But now I noticed that my favorite bubble cloud wear watch face no longer auto updates live weather or show the accurate phone battery percentage on my watch. And that according to developer is cause Samsung changed how background processes are handled in new AVK6/7 firmware which breaks that. And that which I have been using I can not fix. So simple solution downgrade software and add watch 5 pro as my other device to no update list! After all, if it ain't broken, don't fix it. So yeah sorry for long post, just want to know how to go from current AVK6 to previous October AVI4 cause everything there worked perfectly for me but I couldn't find any concrete info about it so posting here since you all are discussing about sideloading firmwares.

For downgrading it's only dangerous if bootloader of the watch is not the same. Or is there anything else I should be aware about?

I use Samsung Pay on my watch and certainly I don't want to trip Knox. My rooting days are long gone since everything runs fast and have plenty of storage nowadays.
However, I might have ran into another issue - I can't find Canadian AVI4 firmware. Maybe there is an program that could retrieve it?

The firmware will have to be the same thou as Canadian varient of Samsung LTE watches have different modem hardware as far as I know.

    Nice.

    I can now also change CSC WITHOUT Root.


    Need few minutes to charge battery.
    Then I can also check if local FOTA Delta aka update.zip work...

    Now I am on SM-R875F AUGF...

    If I am on GVK6 I can check again if still CSC change work.

    I have installed GWA3 Update on my German (DBT) SM-R860 via FOTA update.zip Delta file...

    From GVK7... with help of earlier mentioned System Shell exploit...

    Here is the Delta file:

    GVK7 --> GWA3 SM-R860

    Step 1 is to push the file to device with ADB.

    Code:
    adb push update.zip /sdcard

    For Step 2.

    Later... I need some tester... to confirm...

    But in general Exploit... then Command for FOTA Admin... looks like my Screenshots...

    OWN RISK!

    @adfree 1 more question.

    I think we don't changed the CSC as fully.

    View attachment 5817433

    As you can see, there are 1 more CSC file that we need to change, Samsung Pay can't adds my card, so there are a problem.

    We need to change "omcnw_code.dat" too. But I can't copy it to /efs/imei because of permissions. If we can reach to temporary root access, we can do it too and it's gonna work properly.
    in my gw4 r895f i change dbt to btu and then did a full reset. and at the start got a choice between uk and ireland. I check omcnw_code.dat and get btu. probably need to do a full reset after changing csc

    No idea when Full firmwares for study leak...

    Meanwhile to understand maybe more about funny Region... helpfull this Android App to check Firmware:

    It is possible to decrypt from Test Server...

    Then maybe more clear...


    OXM seems also for DBT ZTO and so on...

    A
    In theory linked FOTA Delta should work for AUGE DBT or SER or ZTO...

    Question is only how to update manually...

    B
    Roll out official could be in waves... but could be also more funny like we allready knows...

    We will see the future of GW4 support.
