Hi Guys,
Sorry if this has been mentioned before but is there a way of entering Samsung Service Mode i.e. to change network bands and to lock cells? it seems disabled from the Oreo update.

Hi there
As above I entered a service menu on my Samsung Galaxy S6 *#9090# it brings up DIAG menu I believe - I may have changed one thing I'm unsure?
Is the default for RAMDUMP Off? I have it as off atm but unsure if it was off or on when I first went in there.
I was trying to have my phone lock on LTE Band 28 700Mhz which is one of the spectrums Optus in Australia use and it gives me the best signal strength at home and at work
Thanks in advance
Hi,
I have a problem with my Samsung Galaxy S8+ (G955F) model. The phone shows Carrier ID: VOD (I guess means Vodafone/Product Code) in Odin Mode in Red Color, the phone is unlocked working on one carrier in all LTE/3G/2G networks but on other carrier it only works in LTE/3G modes and when i switch it to 2G only it doesn't register to a network on this second carrier and as long as i Turn it Back to LTE/3G/2G it registers but to only LTE or 3G.
I believe it is some kind of a partial carrier lock where the phone is locked on some carriers in different network modes.
Its not registering to 2G on Telenor Pakistan Network while it registers on LTE/3G/2G perfectly fine on Zong CMPak.
The phone doesnt require any kind of carrier unlock code or something.
Is there any way to work this around??? I have installed UK BTU Firmware from Sammobile, already debranded and works perfectly fine just not working in 2G mode on this one carrier.
Is there any way to change this product code or something while being on official Stock Firmware?
My Current Service Provider Version is: PAK/PAK/VOD
I want to change this to PAK/PAK/PAK and remove that Carrier ID: VOD thing from the odin mode display.
Please help!!!!!
hi did you find a solution??
Nopes. I just had to change my phone after all the things I tried, It won't go so I had no other option.
Forgive me if this has been covered but I havn't found the answer. I've flashed just about every phone I've ever had but my question here is can I / how do I flash to where the phone reads as XAA in download Mode?
The situation is my phone was originally on at&t. They unlocked it and I'm on Verizon. It all works great (it still says at&t on download Mode screen)
My problem is that if I log into the my Verizon app it disables my visual voicemail. I finally got a Verizon tech on the phone that explained that it is unsupported due to originally being on a different carrier and their system identifies that and disables the VVM. The only fix I can find is to put my sim in my backup S9+ that came from Samsung unlocked (or any Verizon phone) and I can then reactivate my VVM by resubscribing.
I currently have 3 Note 20 Ultras. One Each originally from Samsung, ATT and Verizon but the AT&T is the only one that is 512GB or I would just switch phones. I have flashed them all to U1 firmware but notice they all still reflect the original carrier in Download Mode so again my question is can I change this by flashing it / or is it just a matter of what sim card is in it when it's flashed? I need it to be seen as XAA by Verizon system so not to loose VVM... Pics attached.
Any advice here is greatly appreciated in advance.
Just a try... You can try the *#272*imei# method... But thats If it works. Not sure if the sims has to be in the phone for that to work.

Yes it brings up this menu... So I just select the XAA and that's it? I've been reading forums and this method is reversible it seems ... I'm familiar with Odin and all that but these hidden menus are new to me...
Thanks for the reply btw
You may have to activate the bottom most option to stay.
Don't worry if you can't access the menu after the change. You can download samsung band selection and change to automatic or one of the lte options then back to automatic to get to the menu.
CSC Guide
CSC (which I think means Carrier Service Code) helps to set what options for settings show in the device for things like voicemail and wifi calling, as well as sets network code information for things like carrier aggregation combos.
When you go to your phone settings->about phone->software information and look in the Service Provider SW ver. section, you will see as the last line a combo like XXX/YYY/ZZZ. This indicates what carrier sales and network code is set and what brand the phone was manufactured as.
I think of the XXX/YYY/ZZZ configuration as follows
XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus
YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands
ZZZ=Manufactured as Code- What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECESSARY TO CHANGE THIS.

Hello, so recently I just got a S21 ultra unlocked (sm-g998u1) and been having some problems. I currently have verizion and the problem being is that unlocked samsung phones cannot connect to verizons 5g network out of the box yet (to my knowledge). Prior with my previous phone (s20+ 5g unlocked), I used the *#*#27663368378#*#* access mode code though "phone by google" to manually turn on the 5g bands to be recieved (plus dss), which it worked.
With my new phone, it seems that none of these codes work, being the one above and the *#272* imei code to change carrier config. When I put the codes in, they just erase themselves. Was the access codes changed on the new android 11 platform? Or maybe im missing something? The s21 ultra states it is in a 5g connection by the notification bar status, but speedtest by ookla states its a lte connection, so just a placeholder. Also, it seems that none of the 4g switcher apps worth either, which I would have to guess are also tied into the access codes.
Hi all, will this phone work on Verizon and support Wifi calling, also any fresher roms?

I think it depends on the phone's baseband build. IDK about other ROMs.
When my S10e is in Airplane Mode and then I connect to either of the two Wi-Fi sources in my home, "T-Mobile Wi-Fi calling" replaces the "Airplane Mode" indication at bottom of pull'd down notification shade (versus notification statusbar, which still shows airplane icon). This works about 9 times out of 10, i.e. once in awhile it stays in airplane mode, makes me turn off airplane mode in order to make a call (Tmo's choice, I guess, because I keep Wi-Fi Calling enabled in Settings). But my S10e is running on the latest stock Tmo baseband. IDK about Verison.
