Mercy.

I am NOT willing to waste my time...

AGAIN.

Rename 2 files... then unpack


This is NO Rocket Science...

I have NO idea where exact you fail...

I have no Crystal Ball.

And I have also other things to do...

I will NOT reupload...

LinkS are still valid.

SOSdesasterRepair TAR only without prism.img and super.img.
So - 2 files... the 2 biggest files...

USB cable connected... so ODIN action...

Best Regards

Edit 1.

Seems I have something like this:

Maybe I can find what no PDP sceanrio means...
Or by Enemenmuh I can find why...

About eToken... Combination Firmware...
Look at Photo:

Seems it is possible to erase something... maybe steady.bin dead by some action...
Result is "Allow FAC"

Photo from SM-R875F...
User told no luck with SM-R875U Firmware... as Modem not work...
I think he mean eSIM...

He not test Combination Firmware... but I am sure it could work...
No idea if netOdin is enough or only via USB cable...


About CSC change...
Tried few "free" Tools...

Seems Modem COM Port required...
Not sure I am tooooo lazy to test my Phones...

Example:
SamFw_FRP_Tool_v3.1.zip

This I was able to start without Virus Warning...


The other Tool from here:

Antivir remove DLL...

But main problem for me... seems 64 bit Tool...

And my Test Notebook only 32 bit... Windows 7...

So not start...
I am tooooo lazy to check with other PC...

Best Regards

Edit 1.

Oh, Developer answered...
No its all done through modem, it doesn't do CSC change over ADB at all.

Not direct to my Question... but this is exact what other Tool suggest...

You need MTP or crap to see Modem Driver...
No idea if it is possible on GW4 and/or GW5...

I have heavy problems to enable ADB over USB cable...
So IMHO this will be not easier...

Best Regards

Before I waste my time with 4 GB super.img...

I will waste some time with smaller prism.img...

A
from EVA8 not extractable with 7Zip so additional steps required like imjtool IMHO...

B

I am unsure if I can use netOdin or Odin or dd...

C

I am toooo stupid to show proper my findings... I am using TAB in Editor...
Code:
Filename/inside Firmware    Partition    inside FOTA/Delta as Full File        inside FOTA/Delta as "Patch"

super.img            p30        ------------->                odm.patch.dat + product.patch.dat + system.patch.dat + vendor.patch.dat
tzar.img            p9        yes

Maybe somebody have better idea...

D

Okidoki...

Seems I have to go the dd way...

After so much trouble with netcat direct to PC... I am going the good old way...

Okay still tooo hot bigger 3000 MB...
Code:
freshbl:/sdcard # dd if=/dev/block/mmcblk0p30 of=/sdcard/dumpSUPER.bin
10485760+0 records in
10485760+0 records out
5368709120 bytes (5.0 G) copied, 222.376750 s, 23 M/s
freshbl:/sdcard # exit
freshbl:/ $ exit

D:\Android\ADB>adb pull /sdcard/dumpSUPER.bin
[ 37%] /sdcard/dumpSUPER.bin

But for prism.img perfect way...

Code:
D:\Android\ADB>adb shell
freshbl:/ $ su
freshbl:/ # dd if=/dev/block/mmcblk0p31 of=/sdcard/dumpPRISM.bin
1228800+0 records in
1228800+0 records out
629145600 bytes (600 M) copied, 34.618687 s, 17 M/s
freshbl:/ # exit
freshbl:/ $ exit

D:\Android\ADB>adb pull /sdcard/dumpPRISM.bin
/sdcard/dumpPRISM.bin: 1 file pulled. 2.5 MB/s (629145600 bytes in 237.542s)

Btw. only this dumped p31 dump was able to be patched...
imjtool have some additional Bytes... and fail...

But IMHO I have now prism.img from FVD4...
Soon I will write p31 via dd and look if my SM-R870 EVA8 will explode or accept this FVD4 file(s)...

Best Regards

Edit 1.

Oh... tiny correction... seems generated AVB valid file... so will try to flash via Odin...

Edit 2.

Ohoh.. wrong idea...
Odin hangs and not finish after many minutes...
Seems not possible to reach recovery... automatic into "Kies Mode"...

I was able to flash Original EVA8 prism... so SM-R870 still alive for more stupid ideas...

Edit 3.
Added Pic from up_param... this is how it looks + some cryptic Battery info

I am tiny step closer to FVD4...

Code:
D:\Android\ADB>adb push prismX.img /sdcard
prismX.img: 1 file pushed. 1.1 MB/s (629145600 bytes in 533.692s)

D:\Android\ADB>adb shell
freshbl:/ $ su
freshbl:/ # cd /sdcard
freshbl:/sdcard # dd if=/sdcard/prismX.img of=/dev/block/mmcblk0p31
1228800+0 records in
1228800+0 records out
629145600 bytes (600 M) copied, 68.742835 s, 8.7 M/s
freshbl:/sdcard # reboot

Rebooted proper and showed FVD4 under CSC... after:
Code:
*#1234#

In Standalone Mode...

Now trying to Factory Reset and look if pairing with Phone possible or...

Best Regards

Edit 1.

Nice.

This seems to work.
Positive Sideeffect. No f%$ing FOTA update...

I am only scared... because prism.img was unmodified "Original"...

And for super.img I have many things to prepare... and maybe Security bypass mandatory...
Autch...

Please.

Maybe somebody has older leaked Firmware for SM-R870.


I have only EVA8 and my f$%ing FOTA...


Need files for study.


Thanx in advance.

Best Regards
I can get access to 1DUK1
Could you share the stock firmware of SM-R925F (GW5 Pro International variant)?
No, I don't have access to F model firmware

Since Tizen...

I have never any Watch nor Phone with eSIM.

So I have 0 own knowledge about eSIM.

All I "know" is eSIM is more joke... as easy to handle.

I love my old SIM cards. I can hold them with my big fat fingers.
I can cut them if they are tooo big after 20 years...

eSIM sounds more pia... with all this Security Region Lock crap...

Sorry, my private opinion.

    Will try to simplify for me...

    mps_code.dat: 1 file pushed, 0 skipped. 0.0 MB/s (3 bytes in 0.008s)

    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...

    Okidoki... reason for landing in XSA or depend on prism.img... is inside
    Code:
    /etc/sales_code.dat

    I am on AUGF OLB on my SM-R875F...

    Attempt 1.
    Code:
    freshul:/prism/etc/carriers # rm -r BRI
    rm ro dir BRI (y/N):y

    Ehm... need some time to think...

    try '/dev/block/platform/10500000.dwmmc0/by-name/prism' type 'ext4' on '/prism'

    Edit 2.
    Reboot work so far but still XSA...

    FAC Reset not tested... maybe better I edit salescode.dat to TGY before...

    Now dumped...
    Code:

    The hard part is IMHO valid for netOdin/Odin... also for my rooted device
    1
    Not sure if Sa.sung plays tiny Games...

    My SM-R860 is on GVI3...
    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

    Edit 1.

    XmitData is not new to me...
    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
    1
    Oh great.

    15 % Battery is around 30 minutes alive in Download Wireless...

    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...

    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.

    Edit 1.

    Step 1 done in funny riddle... puzzle...

    Need more time to correct the other props...

    Goal is to enter exact Playstore for GW4... and/or Samsung Apps...

    In Emulator on PC...
