[Samsung Galaxy A50 Questions & Answers] SmileyO'Brien:
Hello,

TLDR:

Bought a second hand Galaxy A50 with DRE (so DREI network operator) branded, which connects very slowly.

My phone, which is exactly the same just CSC ATO (open, no branding), connects nearly immediately.

What settings can i tweak or change before i flash, or where can i download CSC ATO for firmware flashing?

What were you trying to do? (root, install a mod/rom...)

i bought a second hand Galaxy A50 (SM-A505FN/DS) for a friend, did not check it is pre branded with DRE (so Austria DREI) network CSC, did not even know about that problem beforehand.

Otherwise it has virtually the same hardware, firmware and software.

What is the device doing now? Bootlooping, will not power on, stuck in bootloader/Fastboot mode...

Now it takes up to 2 Minutes to find the HOT network he uses it with, after a reboot or after turning Mobile Data on and off.

It is very fast in places with good connection and also nearly connects instantly, but he lives rather remote on the farmland and there it nearly always is a problem, also if he moves around it constantly loses connection.

I have the same phone with ATO, so Austria Open, and it connects in less than 5 seconds if i use his HOT sim card, even in that remote place and when moving around.

>> Searching for solution:

Before i start trying to flash it to ATO might anyone be able to tell me what that DRE CSC probably does different and if i can change that, so it connects as fast as mine does and does not lose connection?

>> What i tried:

1.) I tried checking the logs with ADB, but no real clue what i should search for or if i find any useful information there.

2.) I watched videos to dump my firmware and flash it to his phone, which requires bootloader unlocking and deleting all of my data i might want to prevent if possible (AFAIK).

Can this be done without having to restore my 100GB Data?

3.) I did not find the ATO firmware to download somewhere (hope i did not overlook).

Even links on this site here to download firmware are outdated or lead to long lost websites.

If anyone can point me to a legit site to download that, i would surely try that next.

Like this one:

[STOCK][ROM] Samsung Galaxy A50 (SM-A505F/FN/FM/GT/GN/W/U/U1))

SM-A505U Android 9.0 Pie Firmware download: here ro.product.manufacturer=samsung ro.product.model=SM-A505U ro.build.product=a50 Country: USA Multi CSC : OYN Xfinity Mobile (Comcast) SM-A505UZKNCCT Firmware Update Info: ro.build.PDA=A505USQU3ASL6...

xdaforums.com

Leads to (please do not follow ??!?!):

boycracked.com

ww12.boycracked.com

Or can i try SamFwToolSetup_v4.9.zip if that is safe or can that even set it to ATO?

This has only ireland CSC?

4.) I tried setting the network operator manually to connect to a HOT network, but also does not help.

HOT seems to be in the DREI network, so maybe that's why it even connects to HOT, i guess.

5.) I tried downloading google carrier services app, to no luck.

6.) I tried changing the CSC with the *#272*IMEI_Number# code, but that does not work anymore with Android 11 as i googled.

7.) I tried searching the forums here, but holy cow that is overwhelming and i give up now after 10 different tags with hundreds of results :(

Root status, if you know (Rooted, not rooted)

> Both devices not rooted

Bootloader status, if you know (Locked/Unlocked)

> Locked on both devices

Any pointers what to do next or what best next step aare appreciated!

Thank you!
