Any luck with this? I am thinking about buying a Sprint A50 (SM-A505U) and flashing it with the T-mobile firmware (SM-A505U1) TMB. Wanted to see what your experience was before I made the purchase. I need the phone to work on T-mobile.
Hello a few months ago i purhased a galaxy a7 2017 ds from ebay. The phone was android 7. Everything was ok until i upgraded to android 8 with odin. Then the network locked and i cannot make or receive calls. When i try i get a message of unregistered network. I tried to reinstall the rom with odin but same results. Both of the imei are shown and are clean. What can i do? The rom version is A720FXXS9CTJ2 brazil
Forgot to add that my carrier operator stuck to greek cosmote. My new sim is vodafone. When i insert the sim. I get the welcome to vodafone message. My contacts are there but not network registered. Sim info shows the operator as cosmote and not as vodafone
Hi! Did you solved it?
Make sure your imei from phone box and phone be match!
flashing new rom changes 'efs partition', which have your imei registration infos!
Useful to reflashing firmware from sammobile with re-partitioning option on (by pit file) !
If not works follow this: ref-a-2017-modems-and-bootloaders-collection.
I have 2 big problems with my Samsung Galaxy S20 Ultra 5G Android 11! Bought it in Spain, have installed Samsung Firmware through Samsung Menu and BOOTLOADER ID is EUX(is from Samsung itself)!!
Bought the phone in Vodafone shop so this is my service provider Software version: SAOMC_SM-G988B_OXM_ATL_RR_0030 ATL/ATL_ATL/EUX/ATL
I bought a Network Unlock code installed a PHE stock rom firmware but didn't change a thing! So I don't know if the Network Unlock code worked or not because it stays registered at ATL=CSC code Vodafone(Spain)
Tried to uninstall pre-installed service provider programs, got some definetely uninstalled but not all of them, reinstalled an other stock firmware PHE again and nothing got changed again!
So now I need help from real wizards to help me with this problem!
I want bootloader ID CHANGED to PHE for example and want all pre-installed programs definetely uninstalled from my device, at the moment they get automaticly installed at the end of installing new firmware!
Doesn't something exist to format but real format as a SDD from a PC? Something like that should be found out that we can wipe everything and start all over again!
Is there not such possibility with unlocking the bootloader and installing new stock firmware again? I tried that but it fails, does someone now there a solution for?
Network Unlock Code to use to Unlock the Network lock code is locked now because it was a bad code they gave me and now it is asking for a MCK. Anyone knows how to get a MCK code?
Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?
Two options
1. Get into recovery and do a factory reset
2. Flash the latest firmware ( F926BXXS1BVB3 ) , firmwares are now Multiregion so no problem with that

If that doesn't work , maybe you lost your EFS partition ( it contains your IMEI info ) and that is a big problem
You will have to read a lot here @ xda to try to recover it ( if it'spossible somehow )
Thank you kindly for the information and reply as it is really appreciated.
I can see both imei numbers on the device if this is what you mean? Ironically when the phone is on WiFi with WiFi calling enabled and the simcard plugged in, it allows me to make calls with my number sending to the recipient, it just won't do the same when the WiFi is disabled, I can not communicate out by data nor voice and it keeps saying "not registered on network." I have checked and the phone is not network locked and is clear for use. I will try the firmware link you have sent however if this does not work, may I ask what you think may be next?
To add I have tried various firmware which did not work either.
Can anyone help with this as the above unfortunately did not work.

When you flashed stock firmware , did you use CSC or HOME_CSC ?
You have to use CSC , to get a fresh install
If possible , once flashed get into recovery to perform a Factory reset from there , maybe this can get back the EFS partition that seems to be corrupted
again ... DON'T use HOME_CSC

Thank you for your reply. I did use csc and followed all your instructions. Unfortunately still the same. I am so lost as to what to do as I love the phone but can not seem to fix it.
