CID is a country lock. SIM is an operator lock. Different stuff
CID-Lock locks the device to ROMs that are only from the same country.
e.g.: You have a German PDA which is CID Locked... The PDA will accept German ROMs, but it won't accept English ROMs.
SIM-Lock locks the device to one operator.
e.g.: You have a German T-Mobile PDA. Your phone will only accept German T-Mobile SIM cards. Sometimes it even matters if it's locked to a postpaid or prepaid card. (for example: older Vodafone NL phones which have been given with a contract won't accept Vodafone NL prepaid cards even though the MCC+MNC (service provider network code) of both operators are 20404.)

Rooting and unlocking japanese Android phone

Are there any risk for rooting it,flash a North America region rom and install a baseband that doesn't have a sim lock?

[Q] Will phone from another region work properly?

Can anyone tell me will it be a problem to use Z1c from another region.
I'm from Serbia (south-east Europe) and want to buy second-hand phone originally made for Sweden.
Will it work everywhere in Europe?
If i face with bad signal problems, will it be possible to fix it by flashing my region firmware, or this is hardware problem?
Sorry for silly questions, but I'm not sure if I'm going to waste my money...
It will probably be totally safe without the need to flash any region firmware. If by any chance there are issues you can always use your region firmware.

Thanks. I just wasn't sure if it's 100% firmware related, and not hardware issue.
But few minutes ago I found in gsmarena that network bands are compatible in whole Europe.
If someone needs info about their device, it can be checked here...

Exynos S9 locked itself to a carrier?

Hey all,
I was given an S9 (Exynos version, unlocked, SM-960F/DS) that had TWRP installed on it, but was stuck in a boot loop. After messing with it for a while, I stuck it in a drawer and forgot about it until recently, when I pulled it out and decided to just restore it to stock. I downloaded a ROM for that specific model from this site ( https://forum.xda-developers.com/galaxy-s9/how-to/official-firmware-thread-regions-t3765015 ) and flashed it using Odin. This got the device to boot fine to the setup, but it defaulted to German, and rejected any SIM I put in it, even though the phone was originally unlocked. So my question is, now how do I remove the SIM lock again? I'm guessing I'll first have to wait the 7 days for the OEM unlock cooldown to elapse again so I can reinstall TWRP?

TWRP/Root/Custom has nothing to do with SIM locks, you'd need a sim unlocking service for that

Then why would the phone start demanding a PUK for any SIM I insert into it after flashing, when it didn't before? The SIMs work on any other phone I try them in.

Because certain SIM unlocking services depend on you not wiping the phone in order to keep the unlock
You'll need to unlock it again using a paid service

The phone was never locked to a carrier -- it was purchased sealed, factory unlocked.

In that case check it has not been IMEI blacklisted due to non payment of contract or reported stolen, you state in your OP it was given to you
If it is IMEI blocked there's nothing XDA can do to help you

What I meant by that was that a friend of mine handed it to me to try to fix after he messed with it in TWRP, getting it stuck bootlooping in the process. He had bought it factory unlocked. I checked the IMEI, it's clean. It's demanding PUKs for any SIM I put in it, even though those SIMs work in other phones; I tried a Ting SIM and a Cricket SIM.

Well the only thing I can think is to flash a stock firmware for the region you are in, pick a carrier firmware to force the CSC change, Multi-CSC that contains Germany will default back to that if that is what the phone's original CSC was, but I doubt CSC is causing this
O2U CSC (United Kingdom) for G960F is a single CSC, flash it using CSC and not HOME_CSC along with the other 3 sections
But it seems to me this was not originally a factory unlocked handset, it was unlocked by an unlocking service and sold as one
If that doesn't work, pay for an unlocking service

Is there a way I can find out what carrier the phone thinks it's locked to, or would I just have to get SIM cards from around the world and try them?
Can I do this without enabling OEM Unlock (so without letting the phone run for 7 days)?

Samsung Phone INFO will tell you the current CSC, but if it defaulted to German either you flashed a German firmware or that is the default CSC
OEM unlock is only needed for custom
Flashing a Multi-CSC ROM such as BTU for United Kingdom will have the greatest chance of it defaulting to it's original CSC
I used that app, and it indeed says the phone's CSC is German, Deutsche Telekom from what I could tell. I tried flashing a number of different FW packages (including the UK and Singapore ones) but it still defaulted to German each time.
I tried going to their unlock page and entering the IMEI, but they have no record of it being sold by them.

Like I said, try flashing a carrier branded firmware like O2U, it cannot default to German if that CSC is not included
Flash using CSC and not HOME_CSC
Sim lock is on its own secure enclave chip, so if this was truly Sim unlocked then it isn't even possible to "relock". Either was unlocked in an unreputable way, or is IMEI blocked as mentioned before.
So I just got time to re-visit this project. I flashed O2U firmware, and it defaulted to English and shows the corresponding CSC. The phone is still locked, and I checked a bunch of IMEI blacklist checkers and each one comes back clean. At this point I accept that the phone is actually locked by a carrier, so I need to instead figure out how to get it unlocked, and to do that I need to figure out what carrier it's locked to. Like I said earlier, I tried entering the IMEI into Deutsche Telekom's unlocking page, and they have no record of them having locked that phone. So how would I go about figuring out what carrier it's locked to? If that information is on its own secure enclave chip, is there any way to read it?
Afaik german providers are forbidden by law to simlock phones for several years already. Problem must be somewhere else.
Try entering the PUK of any SIM if that's what's requested. It should be on the full size SIM, else contact your mobile network operator.

Question about flashing a stock KDZ rom from a different region

Hi all, I currently have a G7+ with the model number LM-G710EAW. From this site, there's a few EAW's that get the android 10 update, that is the HK, KR, and SEA. To this day, my phone is still on Android 8. Since that the only way to check the phone region via IMEI is now gone, I have to assume that my phone's region is IDN (I bought it in one of Indonesia's domestic store). With that, I have a few questions
1. Is it safe to flash a SEA KDZ to a IDN phone? Is there any possibility of bricking it?
2. What about the baseband compatibility? Can I still use the cellular network?
3. Is there another way to check an LG phone's region?
Thanks in advance!
