Hi,
I have lighting rom 6.1 installed XXKH3 (what this means?? XXKH3??), I have a Samsung Galaxy from Portugal and my 3g / data only works when I do a factory reset and in next boot it goes away. Even if i try to create an APN it crashes when i select New APN. I tried to change the CSC to TPH (portugal) with the *#272*......, also installed a MultiCSC OXXKE2 because the lighting rom didn't bring TPH, and also copy the CSC portuguese files with a .zip in recovery. First time after selecting TPH in *#272 everything works good, but next reboot stop working again. I checked with *#272 that TPH is selected and i don't understant what is happening. Please help because i can't use internet.
Thanks,
Raven
i have the exact problem!! Cannot figure it out...
Same Rom, same kernel.
Flashing another ROM (wipe) doesnot solve the problem... Aiaiai.
Have you tried flashing other modems?
Sent from my GT-I9100 using XDA App
After trying to install few custom ROMS namely DR. Ketans and SimplRom I experience SIM removed error problem.
The flashing goes fine with full factory reset (only internal SD is not wiped), I enter the PIN when I'm asked for it. The SIM is unlock but when the phone registers on the network it gives SIM removed error and forces a reboot.
I also upgraded the bootloader and the modem to the latest versions BL_N910FXXU1BOD2 and CP_N910FXXU1BOC4 but the problem remains the same.
When I restore back to the original ROM (backed up by TWRP) everything works fine. If dirty flash custom ROM over it again there are no problems with the SIM card.
The only conclusion is that T-Mobile has some additional software installed.
The phone is SM-N910F bought from T-Mobile. It has T-Mobile branding on boot and shutdown.
Does anyone now anything about this ?
To update it with my own research.
Apparently the SIM card is lock to Macedonia region. MBM CSC. When installing custom ROM the CSC gets changed and the phone rejects the SIM.
In an effort to resolve this I've flashed DE DBT CSC ROM and the phone won't accept my SIM card.
Currently I'm downloading the original T-Mobile MKD firmware and I hope by restoring it that I will be able to use the phone again.
Also since I paid for the phone in full I intend to contact T-Mobile tomorrow and ask them to unlock my phone.
Will write what comes out of this. Don't want someone else to lose their nerves as I did today
Definitely the issue was in wrong CSC. I've downloaded the original firmware and everything worked again.
But I couldn't stay put and wanted to flash a custom ROM so I went with http://forum.xda-developers.com/note-4/snapdragon-dev/rom-bob4-devbase-multi-csc-safe-bloat-t3033881.
It's a great base ROM stripped of Knox and de-bloated. Most importantly it keeps your current CSC intact.
The procedure was:
Flash original firmware with Odin,
Root with CF-Auto root
Flash TWRP recovery with Odin
Reset data so that it completely goes stock because flashing the original firmware doesn't reset data
At this point I made full nandroid backup
Flash ALEXAND ROM
Uninstall additional bloatware
So far it's working fine.
I hope that this will help someone.
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).

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)

Pretty sure it wont work cuz i live in israel, but i will try anyway.

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.
I was install some custom rom on my S7 Edge Device (SM-G935FD), and after that, my simcard is not available. I tried to install another rom and do flash again and again, and my simcard not detected until now. Please HELP
This will always occur if you try to install any samsung that has the BLCP version but older than the bootloader you had before installing the rom. To solve this you will have to install via odin the latest version of stock for your device.

i had the same problem but flashing the latest firmware didnt solve it for me.
here is the whole story. Any ideas would be appreciated
I have an SM-G935FD Galaxy S7 edge phone from Malaysia. I have it in Greece and as soon as I got it in my hands I let it go all the updates until Android 8. Since then I can't make or receive any calls and sometimes it recognize my sim card (Cosmote) and sometimes it doesn't. Even the times that recognize my network operator I still can't make or receive calls. And of course I don't have any data.
What I have done:
1. Flashed original Malaysian and Indonesian firmware with no luck
2. Activated and deactivated volte
3. Tried different sim card
4. Flashed original Greek firmware (which I thought it would solve my problem but nothing). At root files it has all the network operators enebled as normal.
5. Tried several custom ROMs from Android 7 to 10. The only one that had some result was Floyd 10. The result was that for a minute I had data and couple of sms came from missed calls. But then again nothing. And since the first time I installed it, when I reinstalled Floyd not even for a minute.
6. Tampered customer.xml file for csc folder as a friend from Floyd rom thread suggested but still nothing
7. With a different sim from different provider I have data almost all the time but no calls at all
Hi, so I tried to debrand my S10+ and everything went pretty well, I downloaded the ROM for my country (XEO) and flashed it with odin. Anyway, after reboot I noticed something weird - language was different. It was French and in the settings the region was XEF/XEF,XEF/PRT. After inserting SIM cards it changed to XEF/XEO,XEO/PRT. I tried to flash the ROM again but no avail.
Nevermind, I managed to fix this.
What was wrong and how did you fix it?

I think that the problem was the SIM card blocade. I did flash the ROM without "Auto Reboot" ticked in options in odin and after flashing I went into recovery, shut down the phone, inserted unblocked SIM cards and booted the phone. After doing this I checked the phone settings and it was XEO/XEO,XEO/PRT, so correctly this time.
