[Q] Galay Y flashed, unlocked, still not able to register into network

My Galaxy Y was from mexico, telcel locked and I wanted to flash it with a german version. I removed the netlock via Dokys Toolbox, flashed it with S5360_XXKK6_OXXKK2_XXKK5 version (and some others, too), everything went fine. I inserted my simcard, phone asked me for my pin, booted up, but I still cant register with my local provider.
Dont think I ruined my efs, dokys toolbox telling me it is unlocked, i am not confronted with a netcode text field any more, i even can get my imei via dial code.
So, someone got any idea what i might have missed, broken or has some hint to offer?
greetings

i suppose you must flash the csc of your region to get back network - this is the common working solution to all such problems
yeah flash CSC!
Flashing a csc of my region didnt do the trick, still "cant register to network". I tried both DBT and DTM
The same thing is happening to me but I'm in Puerto Rico.

[Q][N9005] I want to... brand my phone - CSC change

I have bought unlocked N9005 from Germany. The problem is I need to flash very specific ROM related to my home network - T-Mobile PL.
I managed to debrand and upgrade my phone to N9005XXUENA6_N9005OXXENA5_N9005XXUENA2. Works fine.
But now I need to change CSC to TPL and flash N9005XXUENA7_N9005TPLENA2_N9005XXUENA2 - but direct flashing with ODIN ends with usual invalid ext4 image.
What shall I do to flash banded firmware?
PS: *#272*(my_IMEI)# does nothing. IMEI of course checked with *#06#

Odin "Nand Erase All"

If i will nand erase all on my Galaxy S8(SM-G950F), will it delete the download mode?
If i'll do that, can i still just after that install the stock firmware?
Will it delete things that even stock firmware cannot fix?
BTW the phone is OEM Unlocked.
I did use Nand erase all on my s8 and it did not delete the download mode. What problem do you have?

Network is not available
No signal on my phone, did factory reset, twrp advanced wipe everything, reinstalling the stock firmware from smart switch, changed csc and changed back, didnt work.
Check tutorials to fix, from a tutorial:"In the dialer, type- *#197328640# or *#*#197328640#*#*", cant even type that, it will still show me Network is not available.
My IEMI is good, when i type *06# it is working.
Tried my sim card on another phone, it works, on my phone it should show signal even without sim.
Do you know how to fix this?

How does Nand erease work? So odin first erases the nand area, then writes firmware? After that what would happen to IMEI #, won't it erase efs folder?
The issue I have is with Galaxy S8 Active. I bought it a second hand and it was attached to Sprint. That person flashed it and possibly changed CSC to XAA in the phone, but flashing doesn't affect it at all. I have tried flashing T-Mobile or Sprint firmware, but the about phone page still shows XAA/XAA/SPR. There is no unlocked version firmware for this phone and it seems that only 3 carriers had this device (ATT, TMB and SPR) Whe I flash firmware, the progress goes fine and it passes, but all it does is change the build # of the OS.
So I wanted to do nand erase to remove all changes that original owner did, but don't want to destroy the phone.

Replying to a year old thread :|
I've nand erased before a long time ago, it didn't destroyed my phone but I do not remember if it will change the CSC to the firmwares one(Assuming that you use a firmware with the CSC you want).

Actually I do want to become TMB and I did flash the correct firmware for T-Mobile. I think original owner used something such as "Eng boot or factory binary" to go into service menu and change CSC to XAA. There is another interesting thing. When I go to about page, under Service Provider SW it shows G950U, but the rest of the phone is G892U. < I can't get rid of this!
1) Is there a way for me to maybe get Factory binary file which will allow me to change CSC? I did fine combination file, but it was for v2 bootloader, mine is v3 at the moment.
OR
2) Nand erase will do something good and erase the flash memory, unless nand option doesn't erase a specific memory location in the phone responsible for CSC.
Also, how can flashing a phone not do much in terms of really changing something in the firmware? I have not seent this before. I even tried flashing USERDATA file, thinking I would get T-Mobile's bloatware, but it didn't, not even TMB boot logo.

No signal [FIXED]

The problem got fixed a year ago.
The problem was the hardware and not the software
I've replaced the corrupt phone.
how you changed csc as u explained? usually flashing a diferent firmware with another csc will completly wipe the phone a d restore efs info, be sure ur flashing a different csc not included in the original csc pack (oxm and btu r the same csc for example).

Ive flashed my csc to israel celcom(CEL) with RICE Tweaks from my rom and then back to unbranded israel(ILO) with csc selection, didnt helped.
When the problem started to appear it crashed for a couple of minute(no signal) and then came back, now it doesnt works at all

maybe thats the problem, ILO and CEL r both the same CSC (OXM), if you dont flash other CSC it will not completly wipe the efs carpet, try downloading BVO from sammobile and flash it.
before flashing twrp or anyyhing first try your signal with completly stock BVO.
is wifi working ok?
had problems with my first s8 regarding gsm/wifi signal, got it exchanged to get it to work(it was stock untouched)

I will try this out, even though i did deleted the efs folder using odin(Checkbox EFS Clear) and even nand erase all.
Pretty sure it wont work cuz i live in israel, but i will try anyway.

It does'nt works unfortunlly, installed a stock version of BVO, still no signal, everything else is working.

after a full clean flash of the official firmware go to factory reset from the phone settings, if that doesnt work im out of ideas, but after a clean flash, do all the process without the sim card and put it after the factory reset

After a minute without doing anything suddenly, my signal is back but it crashes every time i use it like to answer a call, i guess my antenna is defect, i will return my phone for a replacement.
Hi, have you been able to solve the problem? It happens exactly the same
Yes i have a similar problem, apps crash, phone lags all the time. I use 2 bluetooth devices connected all the time, location is always open, nfc is disabled, i use nova launcher prime. Phone is not rooted. Call drops when there is no reason. Cellular signals complete goes away even though it was at full service a moment ago, then after 10-15 seconds, it comes back again. This phone is making me really sick. I was using galaxy s5 before this and it had a better performance than this one. I have galaxy s8 g950f by the way.

No hidden menu, no CSC, no LTE

Somewhere over the years I apparently lost the carrier directory in /efs, as well as the CSC data - is there any way of getting this back? I'm hoping it's at least possible by flashing back to stock but only as a last resort - I've tried a bunch of different things without success so far.
The phone started as a Rogers N900W8 and was immediately unlocked and rooted. Sometime soon thereafter a Bell 4.3 firmware was flashed (via Heimdall). I then switched from Rogers to Wind (now Freedom) - I believe this is where the hidden menu disappeared if I remember correctly - and the phone functioned just fine through all of this.
I then moved from that Bell BMC 4.3 to the Wind GLW PG1 5.0 firmware (grabbed from sammobile and flashed via Odin) thinking that the presence of the Wind SIM would trigger the firmware to switch from BMC to GLW but it doesn't seem to have worked out like that. I'm now running the LineageOS nightlies and the phone works just fine except for a lack of LTE which is what I'd like to sort out with the secret codes. Also, since switching to Wind I believe my mobile network has always been displayed as HOME.
Samsung Phone Info doesn't list any CSCs except BMC under original. In the firmware tab, it's not listing PDA or CSC version. There is no carrier directory in /efs nor are there any CSC files in the file system. Entering almost any secret code fails "Connection problem or invalid MMI code" - *#06# will display IMEI but all others I've tried don't work.
UPDATE #1:
Have been able to get the Canadian CSCs onto the device and recognizable as being present by Phone Info.
Ripped out cache.img.ext4 from the PG1 firmware and used Cache Ripper (found on XDA somewhere) via Wine on linux to create a TWRP flashable zip. Had to mount system in TWRP before flashing.
Changing CSC with Phone Info apparently does a Factory Reset and not quite ready to do that yet as more research seems to point to reverting to stock for the hidden menu.
UPDATE #2:
Flashed stock PG1 via Odin. Went into a bootloop after building Dalvik on first boot and had to reboot into the stock recovery and wipe data and system, then it booted fine. The back button stopped working (LOL Samsung) and I had to flash a random 5.0 custom kernel (idlekernel) to get it back. Flashed TWRP and SuperSU.
There is now an empty carrier directory in root but there still isn't one in /efs. Lots of information on XDA pointing to this being a prerequisite for the secret codes - turns out it's all bunk.
Secret codes work. Had some difficulties with Phone Info not letting me into the root menus to change CSC - was spitting out output from some failed scripts - and when I was just about to give up it started working. Changed CSC to GLW which prompted another factory reset, and now it shows GLW / BMC as the active CSCs. APNs were Bell's originally, which is not what I wanted, but after following the *#272*IMEI directions from this thread and another factory reset they are now Wind's. No LTE yet. Would like to get rid of the BMC CSCs altogether since this was never a Bell device.
Some more stuff changed in Phone Info: Product Name is now hltevl, Firmware's CSC Code is now BMC and CSC Country is Canada/CA. PDA and CSC version has also been populated. CSC Changer still defaults to having BMC selected and I'm still getting the Bell bloatware.
UPDATE #3:
Active CSC reverted to BMC after a couple reboots...they're all BMC now.
Attaching (the initial) Samsung Phone Info screenshots (don't see how to edit them into OP via mobile app) .
I recommend to flash a stock firmware instead of this custom rom.

Thanks for stopping by.
I flashed the stock PG1 firmware for the GLW CSC. But the device still thinks it's BMC - this probably has something to do with all the Canadian devices sharing identical hardware and firmware.
Then I used your tool to change the CSC to GLW. All of the CSCs remained BMC except for Active CSC which was BMC/GLW. After a couple reboots even that was gone and Active CSC reverted to BMC.
Do I maybe need the stock recovery for the CSC changes to stick ? I flashed TWRP 3.1.1 for root.

So your problem is to get LTE back, or get rid of BMC?

I'd like to do both if possible but I'm not going to sweat over the CSC if it's purely cosmetic - mainly concerned about the LTE.
I wouldn't be surprised if they are linked however since the carriers here operate LTE on different bands to the best of my knowledge.
So firstly try to install the stock BMC firmware to see if the LTE works?
Long story short, LTE isn't yet available in this location on this carrier on a Note3-supported band yet.
So that's that.
