I just unboxed my G955FD and put my cricket SIM in and have no response from the network other than pushing an APN and my phone number. I tried manually selecting carrier networks and it listed 5 different "cricket" to attempt to connect to. At one point it showed signal bars in the status area, but no network connectivity. When I automatically connect to the network it responds saying I am registered but no signal bars in status and no activity. I appreciate the help.
Can anyone offer some tips before I call it a lost cause? The phone is out of its return period and probably broken since it will now receive a cricket badge and bars and LTE service but will not make calls or go online
Hey, are you on stock ROM. My 955F works just fine on Cricket, though compared to my daughters AT&T setup, her data is much faster. just discovered this today, and tomorrow will visit Cricket and AT&T to find out why...
Jan 9, 2108 update. I discovered Cricket is limited to about 5-6 Mps. I'm now on AT&T, for a few dollars more for two lines, and can get up to about 40-60 Mps in town.
What region CSC are you using?

Here are my apn settings
Name: any but I input Internet or Cricket, I think it will work with whatever you like.
APN: ndo
MMSC: http://mmsc.aiowireless.net
MMSC proxy: proxy.aiowireless.net
multimedia message port: 80
mcc: 310
mnc: 150
apn type: default,mms,fota,hipri,supl
I know when I've setup APs on other phones there have been times that I will first do a 'reset' of my network settings on the phone, then reboot. Sometimes that will help. After that I will enter new APN settings and reboot.
On this 955F, with a viable CSC my phone just finds Cricket and works. With a bad CSC, it may list/show the cricket or AT&T networks, and will not register, no matter what I do, and for how long.
For example, my phone initially had a stock F ROM and a Panama region for the CSC. It worked with Cricket straight away. I changed the CSC to XAA using AT&T, and would find the towers, but would absolutely not register/work.
I ended up installing CarHDROM - a Note 8 OS ported for the 8+, and It took me a bit to find a CSC package that was meant for the ROM (Note 8) I was using, meaning I had to use a Note 8 CSC, even though my phone was an 8+ 955. Once that installed, Cricket started right away.
The CSC that came with CarHDROM I don't think worked straight out, but I can't recall for sure. I did end up using a XAA CSC, for the Note 8, non-AT&Tand that solved my connection issue after I had installed the CarHDROM.
CSC and phone wise, the ROM takes precedent, and the CSC must match the ROM (model). Seems that way to me, anyway.
Hope his helps.
There is another post about a FD phone that won't connect up, as well.

I am on stock ROM. I guess I will root today and change CSC and hopefully that fixes whatever issue is going on. I have seen the cricket badge and LTE bars recently but no registration on network. If not, the eBay seller said they will take the phone back I'd it's indeed broken.
Ok so far no luck changing the CSC on stock ROM. I am going to try a couple different ROM and CSC combos tonight. Once again I am showing bars and cricket badge but not connecting data or voice on the phone, after root, and changing CSCs. I feel like Im so close and passed up my last day to return to eBay seller so I hope it truly is software and not hardware related. Im thinking of going by AT&T to act like a potential customer and see if its cricket messing up. Any other suggestions to try before I go crazy and use this phone for target practice?
Is it possible this is a region lock issue? My phone is a Tawain version and it was brand new out of the box. There is no sticker on it mentioning region lock. Does anyone have any insight into region locking for outside EU devices?

Good question. I have a 930S Chinese region and it pulled in ATT/Cricket/TMobile just fine. I did have problems when I flashed a custom ROM, and flashed the CSC that came with the ROM. Later I flashed back the OEM CSC for the region (China) and it worked perfectly, again.
If you do flash a custom ROM, make sure you get a CSC package that is meant for that ROM (model). Not the exact model of your original phone. If you can find an XAA CSC that is meant for the new ROM, should be perfect.

Ok I have been changing CSC through TWRP with the CSCSelection Utility. Is that what you are referring to with flashing CSC? Is there a more effective way to do this through Odin? I think tomorrow morning I am going to flash back to stock firmware and start over. Am I able to flash any stock firmware for the SM-G955FD through Odin or do I need the original firmware for my region, which is (BRI) I believe I remembered reading I can flash everything for that model, but not any North American firmware meant for the SM-g955U

Just flash the CSC that comes 'stock'/with the rest of the full, stock firmware set, Odin will work. Have the SIM in the phone before you reboot, as for me it seems to help.
I haven't found a difference, for me yet, just flashing the exact CSC through Odin or TWRP. As I'm now on a custom ROM, I'm usually flashing via TWRP with a CSC that is supplied by an Aroma setup. Aroma is very handy.
Yes, flash your full stock via Odin. If you have TWRP you will lose it. You can re-flash TWRP from Odin. I typically flash TWRP all by itself, but I don't think that is really necessary. Maybe someone will come along and let us know.
As an aside I always keep a copy of zips/installs of TWRP, re-verity and SU on my SD card.
So after the stock full flash, I reboot into download mode and Odin flash TWRP, and follow that by a direct 3 key reboot into recovery, and TWRP will load. If you are going to root then flash re-verity, then SU/Magisk. You could then flash your CSC, but with the issues you've been having, I'd then boot to system, do the initial setup of the phone, and then boot back to recovery/TWRP, backup the phone.
Then TWRP flash the CSC Aroma package, making sure you have the SIM in the phone and reboot to system. I've been using XAA as my CSC with my custom ROM, within that is AT&T, T-Mobile, etc for US phones. I select the main XAA CSC from Aroma. Next I select the unbranded XAA as my more specific/local package, instead of AT&T, for example.
My 955F, stock worked just fine on it's 'stock' CSC (China region). I only had to change the CSC when I flashed a custom ROM, and that ROM did not have the ROM's (model) of XAA, so I had to find a CSC, which had XAA, that 'matched' the ROM I had flashed. I had flashed a Note 8 ROM, CarHDROM,v8 initially. Again, that ROM was largely meant for Europe and Exynos phones, so I had to be pointed to a Note 8 CSC that was compatible with the Note 8 custom ROM.
Yes, Odin is where you would flash stock firmware/stock CSC (not in an Aroma package) for your SM-G955FD. It is my understanding that all non-US phones, eg the G955's, are mechanically the same, so flashing 'any' Exynos ROM, G955FD ROM should work via Odin. You can also flash CSC packages via Odin as well, but there is no Aroma process, to my knowledge/experience. So have the specific and correct CSC to flash via Odin, if you go that route. It sounds like you are aware your phone is Exynos? A non-US phone?
I specifically bought my G955 (8+) as non-US so it could take root smoothly/easily, and work great world wide, including working great here in the US. Sometimes the U.S. does not seem a part of the world.
As I've been messing about with S7's/8s, there have been times that the phone did not grab onto AT&T, for example, and i would then 'reset' the network and reboot, with the SIM in the phone, then do a search for phone networks/services. That usually solved it, but when it did not, and I know I have the right CSC, I would then input/create a new APN, with AT&T, Cricket, Sprint, or what-ever service I needed, then reboot.
The only times I've not gotten the phone/s to grab the networks after that is when I've had the incorrect CSC.
Again, on my stock what-ever country G955F, stock G930S, etc, all Exynos, with the same stock (non-US) CSC that come in the firmware package, the phones have grabbed AT&T/T-Mobile just fine. If it would not, I would have reset the network, rebooted and entered the APN, and then rebooted (with the SIM in the phone). Done a network search after that, if necessary.
Hope this helps.
So today I stopped by TMOBILE and the store clerk popped a SIM card in and it fired up 4G LTE immediately and made calls. I then decided to stop by AT&T and it showed bars but refused to register or do anything even with the APN settings being pushed through from AT&T and Cricket. I am finally happy to realize that my phone is not defective (which I had feared before) and that it must be this service area and the bands on the G955FD. I have wanted to switch to TMOBILE for awhile now anyway so this is my chance to have an excuse to do it. Any input on why it won't access AT&T through an AT&T or Cricket SIM? I'm curious now more than anything. It must be missing a band that this area uses correct? The phone is clearly unlocked and functioning correctly.
What local CSC r u using?
Did you have AT&T check the APN?
T-Mobile and AT&T work on S8+ just fine, but need appropriate APNs.
Head back to the AT&T, if you want AT&T, and see if they will reset and or reinstall AT&T CSC/OS on your phone. XAA/ATT will have the AT&T boot logo. XAA/XAA (generic US use, ATT/T-Mobile compatible) will not.
One ringy dingy, two ringy dingy's...
I have the T-Mobile version A71 5g, model # SM-A716U. I can't stand the T-Mobile branding, especially the jingle on startup.I am trying to flash the generic firmware XAS-A716USQU1ATFB-20200713085932 with odin and it fails every time with a message on the phone.
Odin on the computer does not show any error. Once that process is complete the phone reboots to the bootloader and shows an error message: failed the resizing-data
Is there any way to do this without wiping the phone? I read some things that say you have to log out of google and samsung accounts, would that really make this process fail?

I doubt Odin cares what accounts you do or don't use. Shouldn't have any effect.
I'm not a fan of the T-Mo branding either. The all-pink screen splash is obnoxious.
Sounds like the problem is the internal memory partitions are slightly different between the generic image and the T-Mo image and it doesn't lime that.
So you think for this I will need to factory reset. Do I just select re-partition in odin and then select CSC file instead of HOME_CSC file?
And is there any risk of tripping the efuse or setting the warranty void status to 1?
In the meantime I tried the *#272*IMEI# and this is just such a mess. When I set it to XAS the phone thinks it is Sprint phone and tries and fails to activate. When I set it to XAA then that doesn't happen but it refuses to make VoLTE call and calls over CDMA do not connect for some reason. I am using Verizon SIM card BTW. Also in XAA T-Mobile 5G does not work.
But now it is stuck on XAA *#272*IMEI# does not bring up the menu!

Where are you finding generic (unlocked) firmware?
I've looked on SamMobile & couldn't find anything for the SM-A716U.
As best I can tell, there is no unlocked version of this firmware nor does Samsung even offer an unlocked version of the phone itself.
I don't know, this is all very confusing. Some random websites say XAS is generic firmware, other random site say XAS is Sprint. And then they show a BST firmware too but nobody tries to guess what carrier that is for.
In any case if I used the *#272*IMEI# menu to switch it to XAA and now Verizon VoLTE doesn't work and T-Mobile 5G doesn't work what can I do to revert back to stock since the *#272*IMEI# menu will no longer show up?

Have you tried using Samsung's Smart Switch desktop tool to restore your phone back to stock?
https://www.samsung.com/us/support/owners/app/smart-switch/
Smart switch doesn't give me any option. The old version says this phone is not supported for recovery.
And now I can't even get the phone back to download mode
I am also looking for a way to update my A71 5g to Android 11 and OneUI 3.
I have the model number SM-A716U, the AT&T variant that is network unlocked and on Metro-by-Tmobile.
I have been looking for a way to update the phone but I only found the firmware for model SM-A716U1 which is the unlocked variant.
I don't want to take the chance of bricking the phone.
But the firmware is from AT&T but the model number is different.
There is an update for the right model number but it can't be downloaded anywhere.
Smart Switch also doesn't recognize that there is an update.
I guess I am just stuck with Android 10 and OneUI 2.5
I just bought unlocked verizon s10e and flashed G970U1-XAA firmware to remove bloat wares and have official samsung experience.
However, "Service provider SW ver." still shows VZW. I learned CSC can be changed with Samkey, but does not want to go that far if there is a easier way or keeping VZW doesn't affect anything like OTA updates and possibly some features/software.
I'm on Cricket.
Will there be a issue with VZW CSC code?
Doing a factory reset changed CSC code for first and second section, showing AIO/AIO/VZW.
Apparently, ODIN updating to XAA firmware with SIM card installed wasn't good enough.
And I just got a OTA update for August 1. So, I guess everything is good for now.
Greetings,
I am a new user here. I just bought Galaxy S10e and I really like the phone, but the problem is that I ordered it from USA (I live in the Republic of Georgia). Originally the phone was from AT&T, but the seller had it unlocked for any GSM carriers and it works fine with my Georgian sim card. The only problem is that I do not receive any software updates. It is stuck on Android 9 and One UI 1.0. When I try to check for updates, it says that my software is up to date. The same happens with Smart Switch.
I tried Frija and Odin. My CSC is G970UOYN1ASD9 and PDA is G970USQS1ASD9. There is no way to download firmware for my own country's CSC, because there is no firmware for SM-G970U (Snapdragon chipset), in Georgia they only sell Exynos ones officially. So, I tried to find updates with CSC ATT in Frija and it does not give me anything. I tried XAA and XAS (which is for unlocked phones) and still nothing. I tried TMK (I think it is for MetroPCS) and USC (This one is for US Cellular) and also TMB (T-Mobile) and they do have Android 11 firmware. But now I am afraid I will break something if I install above mentioned firmware to my device. Or maybe I will not break anything by changing the CSC, but maybe there is also a chance that if I install the above mentioned ones, the phone will get locked on these carriers and I won't be able to use my sim card. Is logical, or am I just overthinking it?
Any help would be really appreciated.
Thanks in advance.
don't flash your nations CSC- that shouldn't matter. Snapdragons LTE bands should be good enough to work internationally
go and reflash a USC or XAA rom with patched ODIN... I had to do this for my phone and OTA started working once it was on the correct CSC
you could even flash it to the latest firmware if you wanted too.

Thank you for your answer.
What do you mean by correct CSC? I believe, my phone is on correct CSC now. I have already pasted it and in about phone > Software information > Service Provider it says ATT/ATT/ATT. But it seems that ATT doesn't receive updates outside US.
I cannot seem to find firmware for XAA/XAS, there is one for USC but I have already downloaded TMK. Is there any difference if I install USC or TMK? (TMK is MetroPCS).

Hi GSamkh... Did you upgraded to 11? Im trying to do the oposite, downgrade from Android 11 to 9. If you didnt the upgrade, can you check if the secure startup (or secure boot) its avaliable? Since in Android 10 and 11 isnt...
Seams that secure startup works on Galaxy S9 with Android 10 upgraded from 9.

Greetings,
I have already updated to Android 11 using U1 XAA firmware and it works great. I used Frija and then Odin if anyone wants do to do this. Weird thing happened though - when I flashed the firmware and when Odin did it's job, the laptop suddenly shut down and I couldn't turn it back on. I had to disassemble it and unplug the integrated battery, plug it back on and fortunately it turned on again.
As far as your question goes, I am sorry but I cannot check it since I am already on Android 11.

Hi GSamkh,
I am experiencing the same issue as you, purchased an AT&T branded SM-G970U for use in Australia. After you flashed to Android 11 using U1 XAA firmware, do you now receive OTA updates? cheers
Hey, first post so sorry if I say anything off lol.
I have a G996U purchased from Verizon that I flashed to U1 firmware like 2 years ago when I first got it, and have had no issues since. I had a OTA software update the other night that seems to have triggered a carrier lock in my phone. The phone works fine for 5 minutes, then I get a popup telling me the phone is locked and to contact Verizon, despite the phone being from Verizon and running a Verizon sim. I went to them and unfortunately nothing they did could resolve it (new SIM, eSIM, etc), so they shipped me a new phone via insurance. I'm wondering though if I could save myself the hassle of transferring everything and do an in-place flash on the phone to see if that clears up the issue. I am already on the newest firmware (G996U1UEU5EWB1), so I can't upgrade, but I was wondering if I'd be able to flash the same firmware already on the phone while keeping all my data. Thanks.
Yes, just flash with home_csc.

Thank you, just also want to ask bc I'm actually not sure which software to go for. I thought I had flashed XAA long ago, and I'm definitely on U1 firmware, but when I check "Service provider software version" in settings, it says VZW rather than XAA. Is it safe to download XAA firmware for a reflash or should I just do VZW to be safe?
You can flash any csc firmware.
