Why unlocking befor flashing? - Galaxy S I9000 Q&A, Help & Troubleshooting

I want to flash my samsung with the newest firmware from "samsung-firmwares",
but why i have to remove before my simlock (it´s a branded from A1).
And what happens if I flash without removing the simlock?
Thanks.

I also have the same question on my thread, no body seems to know if we can really flash simlocked units.

errors on boot i suppose ?

So Android phones actually combine simlock with different firmware locking (CID lock?) ??
The hell with that, then. In any other phone we can flash the firmware without the worry about simlock.

i rooted mine and it is sim-locked. never tried to flash tho.
just chiming in that we need some sort of confirmation/assurance that flashing is/ain't possible.

i got the same qeustion, mine is root as wel but can some1 confirm that we can flash the phone when its locked?
and is there a way to check if your phone is simlocked??

Mine is SIM lock (i think, never tested) because it was A1/Vodafone branded when i bought it..
After flash the brand was gone, but dunno with the simlock, as i have A1...

you can flash a locked phone without any problem. it will stay locked though after reflashing. if you flash a generic firmware you will get rid of the carrier personalisation.

No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.
You can do whatever you want to any rom, and that won't affect anything that makes it unlocked
thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....
is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,
Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Can T-mobile still unlock the phone after I rooted it or would they know that I put a custom rom on it??

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

Is it safe to flash simlocked Galaxy S?

Is it safe to flash simlocked i9000 with odin?
IMO theres no connections between flashing and simlock, but want to be sure.
Cheers.
I flashed my simlocked SGS using Odin and I had no problems. There are other few cases in the same situation and they had no problems.
Will a new ROM get rid of the simlock?
no, it wont, this would be to easy to dream of...

No problem to flash, I did it many times already, try also 2.1 and 2.2 android on it, lag fix, etc. Everything working normally...and, of course, the lock remain in place!

Mine is simlocked. Flashed sever times and all is perfectly !
just make sure to run Odin on a windows machine with English US settings
i screwed up a flash because it was running on a machine with Non English US, it got stuck on the 512.pit mode, but it wouldn't continue
My phone has simlock.
But i dont now of i can flash it to JM5?
Somebody now how i can unlock my phone ?
My precious is simlocked and I had no problems flashing other firmware. For example now I'm running a pre-rooted XXJP3 flashed through Odin. You cannot get rid of the simlock by flashing other firmware, you have to buy the unlock code. I'm waiting mine.

Hi where are you getting your unlock from
I tried with globalunlock but they were not serious, I had to raise a dispute/claim to Paypal to get my money back. Now I'm trying with someone from my country (i know his name and address in case of.... )
Hi!
My Galaxy S was locked too.
I tried unlocksamsung.co.uk and they sent me back an unlock code in one day. Everything is fine now.
I got my unlock code in 24 hours using a romanian guy services found on an ebay-like site in romania (okazii). Everything went smoothly and now my precious is sim unlocked
My phone is simlocked and ive flashed it several times already.
Will it be OK then to flash a sim locked tmobile 2.1 with a vodafone 2.2 with the kies registry fix

[Q] I'm rooted and SIM unlocked, BUT!

I have lost my unlock code due to a HD failure. I am currently rooted and unlocked, and I run the leaked Froyo ROM.
What will happen in the future, should I want to flash, say, a Cyanogen ROM (*if* it becomes available)? Will I lock again? I understand my unlock codes were wiped when I flashed the new ROM.
Is there a way to insure I do not become locked again?
I have searched threads extensively, I do not think I have found a consensus on this? Anyone care to enlighten me?
I unlocked back on 2.1 (JF6), updated to JH7, flashed 2.2 (JI6), and have also flashed Cognition Betas 6, 7, 8, 8.1, and 9...and I'm still SIM unlocked. As far as I know, it's permanent no matter what ROM you choose to flash.

That's what I did before I got my SIM locked, was playing around with JH7 a month or two back and somehow got it relocked.

Hmm...strange. I still have my code (saved on both my MicroSD and an external harddrive) but I might start removing it as a precautionary measure.

HTC One M7 Carrier branded Unlocked?

Hi, I bought a my HTC one m7 from Amazon US and it turns out the phone was not Factory Unlocked but a phone from puerto rico that was Unlocked with a Carrier unlock code or something like that, the phone came in a sealed box which is why IDK wtf happened, anyways
I was trying to update my rom from the HTC website and it didnt let me because It said I had the wrong model, so I contacted HTC support and they told me what I wrote first.
So my question here is, I cant return the phone because I bought shipping outside the us but it was from Amazon (I have prime). Can I convert my BRANDED phone to factory unlocked or something? I cant upgrade to lollipop because apparently the carrier this phone had is not upgrading it.
Thanks.

Yes you can convert it but it will require S-OFF
Once s-off is achieved, you have to change your CID number, might also require to change the MID number and then you are good to flash an unbranded RUU.
Ok, are there any risks involving S-OFF? Like bricking, or something else? Cant I just get a rom of lollipop and flash it? Or I specifically need a ROM for my carrier?
What happens if you force flash a factory unlocked rom into a branded phone?
Thanks
rmartinezdl said:

S-OFF disable all protection of the phone enabling you to flash any partition of the phone so yes there are high risks of bricking if you don't know what you are doing.

Yes you can unlock the bootloader, flash twrp recovery and then flash a custom lollipop rom like maximusHD, Nusenseven, insert coin... Some custom roms qill require to update the firmware to a 7.xx.xxx.x version. I'm personally using insert coin 7.0.7 and it works great.
Code:
What happens if you force flash a factory unlocked rom into a branded phone?
You can't. S-ON will prevent to flash any RUU (stock rom) that is not intended for your phone (not for your cid/mid).

Need help regarding my NEW S6 G920T

Okay so i have read a few thread posts but all this seems a bit too confusing. Here is the situation. I bought a used S6-G920T which is unlocked as of now, i don't know what method was used to unlock it since i bought it pre unlocked. My sim(Non T-Mobile) is working fine. I am on 5.1.1- BASEBAND: G920TUVU3DOJ7, what i want to do is update to marshmallow, the official OTA isn't really available as it says the system was tampered with. I want to know if it is safe to update to 6.0.1 via odin without losing my unlock. Thanks in advance to anyone who bothered to read through.
BTW as of now i don't have root access.
What do you mean when you say you're unlocked?
You can use Odin to update the phone to newer baseband and bootloader; you can then use Odin to flash TWRP, and install the ROM of your choice.

I am talking about carrier unlock. I currently don't have any carrier restrictions. Will update cause my phone to become relocked?

It shouldn't, no. You should be able to update and still use your phone on the carrier of your choice.

What method did you use? I don't imagine it would...of course, if you flash a stock TMobile ROM, some TMobile features may not work on another carrier...

That is the issue I bought it unlocked(used) so no idea what method may have been used. I might just go ahead and update. Thanks for the help.

I'm pretty sure the phone unlock has something to do with the IMEI of the phone being tied to the carrier. If it is unlocked, you should be able to use it on any carrier. It sounds like the process takes place in a special partition that is at the lower levels, like the bootloader, and does not change regardless of what software is used on the phone. I'd say just go for it and update, I can't see any reason why it wouldn't work, even after an Odin flash.
