General Firmware and Combination Firmware and FOTA Delta and CSC change and...

[adfree]

Memo to me:

SM-R860

[ro.sf.lcd_density]: [320]

SM-R870

[ro.sf.lcd_density]: [340]

Because this is really helpfull to change density... to play with Phone Android Apps for instance...

adb shell wm density 235

User gave me nice hint for SM-R860...


So need some time to understand what to set for density 340.. is "better"...


Edit 1.

Some Google search result(s):

Display density on Android | blog.mbirth.de

Edit 2.

D:\Android\ADB>adb shell
freshbl:/ $ wm density reset
freshbl:/ $ wm --help
Unknown command: --help
255|freshbl:/ $ wm -h
Window manager (window) commands:
  help
      Print this help text.
  size [reset|WxH|WdpxHdp] [-d DISPLAY_ID]
    Return or override display size.
    width and height in pixels unless suffixed with 'dp'.
  density [reset|DENSITY] [-d DISPLAY_ID]
    Return or override display density.
  folded-area [reset|LEFT,TOP,RIGHT,BOTTOM]
    Return or override folded area.
  scaling [off|auto] [-d DISPLAY_ID]
    Set display scaling mode.
  dismiss-keyguard
    Dismiss the keyguard, prompting user for auth if necessary.
  set-user-rotation [free|lock] [-d DISPLAY_ID] [rotation]
    Set user rotation mode and user rotation.
  dump-visible-window-views
    Dumps the encoded view hierarchies of visible windows
  set-fix-to-user-rotation [-d DISPLAY_ID] [enabled|disabled]
    Enable or disable rotating display for app requested orientation.

Edit 3.

So Value 72 is smallest I can set...

D:\Android\ADB>adb shell wm density 10
Error: density must be >= 72

D:\Android\ADB>adb shell wm density 72

Few tests... SECRET Codes taken from...

I press Return on PC... then run as fast as I can to my rooted SM-R870...

Edit 1.

If all tested will check if difference Space...

<action android:name="com.samsung.android.action.SECRET_CODE"/>

Hi, I own a galaxy watch 4 classic, it is seriously bootlooping, by this I mean no matter what I try it does not boot. I even tried going into recovery mode, the second recovery mode loads, the watch restarts. Please help, I don't know if maybe installing some firmware through netodin will work? I have been able to get into usb download mode

Galaxy Firmware

Download latest samsung firmware for free without any limits.

galaxyfirmware.com

I am pretty sure it is the SM-R890, I got it from At&t as it was my moms, but she got a new one the other day and gave the old one to the tech guy in the house to mess with.

B
My diagnostic came down to firmware update failure that corrupted it, I can`t open anything on the reboot menu besides the usb download so I figured I would try with a different firmware whether its stock or hacked idk I am willing to try anything since it was a free watch.

C
Yes my phone is from Samsung, I am a full on Samsung guy.

Thank you for the reply!

netOdin Tool is here:

[Tutorial] Downgrade Gear S2 (Sport/Classic) to Pair with iPhone again

Firstly, this is not my tutorial, all I do is translating my Vietnamese brother's work to English. So credit is belong to him haihapc2 (he is here as well) Tools you need: Wifi Odin...

xdaforums.com

Youtube Video is here... I have no other...

I know downgrade is possible. BUT I can only confirm from EVA8 to DUK1...

No idea if your Bootloader allow downgrade... So OWN RISK.

Be sure you charge Battery fully.

I hope this is still possible...

Maybe try in Download Wireless Mode to charge Battery... BEFORE Flash attempt with netOdin.

Please... NO Panic.

B

R870XXU1GVH2 is latest for now...

So I can NOT see you have problem now with FOTA Updates...
And we can not test your "feelings" now...


C

NO easy 1 click way back to INU...

Please look A...

It makes no sense to get in panic... if you not need waranty exact now...

If new Firmware comes... after GVH2....
Then you can check Fream vs. Reality...

Argh...

A
I have less luck with WiFi and GVH2 to dump the whole eMMC...

On EVA8 I can remember 3000 MB or 1 time 5000 MB from 16000...

But crap GVH2 not reach 1000...

I see in Developer Setings some WiFi Debug special stuff... will try if more stable Connection...

B
Still no luck with ADB on USB...

With density I was able to see little bit more... but seems not to help...
Was not able to see all text...
After Reset UART not activated...

IMHO param is ovverrride or blocked or... I am too stupid

 

[adfree]

Argh...

Stupid me set XAA for stupid tests... with result...

WiFi not find my Router...

Now testing to downgrade from GVH2 direct to DUK1... to see if downgrade work like allready success from:
EVA8 to DUK1


I can remember to see some US Settings differ to WiFi crap...
Forgotten where I saw solution... but I am toooo lazy to change my Router config nor to debug over BT...

So if Flash okay... I can test few CSC change things on DUK1...

Best Regards

Edit 1.

DUK1 yes...

WiFi no... (WiFi work because I can see other... but not my, Router power off for few seconds... but no luck yet...)

Now I am setting with Phone... as no luck in Standalone...

Before in recovery chache wipe... then FAC Reset...

Hi

Thanks for the reply I appreciate it

I updated the watch to R870XXU1GVH2 before changing the region and hence its on that version, will I get updates later on?

Does changing region void the warranty?

My watch is in the return period window shall I return it as I rather have a watch with warranty than the spay benefit

Can I go to samsung and claim this is how I got the watch and they won't know that I have changed the region?

Excuse me...


A

I am not Samsung nor married with 1 of them...

B

I am not selling GW4 nor other things in Pro way...
So I am NOT Seller...

C

I am from Germany. Not from India...

So I have NO idea how Samsung support nor Seller warranty stuff managed in India... in your country.

D

Maybe you agree.

I can NOT look into Future... I have NO Crystal Ball.

GVH2 is latest for now...

GVIblabla is under Development... but who knows if Samsung release this... or other Version in FUTURE

E

For many things in Live...
OWN RISK


F

But I still can not detect REAL reason why you are in "Panic"...

If Watch work fine... enjoy.

I am not Lawyer...
Not in Germany nor for whole global world...

Does changing region void the warranty?

You can use Google for this...

In German.

Nutz Deinen gesunden Menschenverstand...

And also this is only "theory"... from Future

IMHO you not contacted Samsung... so no warranty "case" now...

Puh... after few hours of crying...

I fixed my problem by flashing 2 files from Combination Firmware...

First attempt failed to flash... because FAC allow blabla...
