Hey,
Do sim locked Desire S phones allow to install custom roms? If so, any different procedure from the normal?
Quite a few threads about unlocking bootloader, etc.. I have to say I feel a bit lost and the one's i've read to not approach my doubt. (Perhaps i've been unlucky.. i really haven't checked every single thread.)
EDIT: That said, i'm not looking for full explanation and procedures... just want to know if it's possible. If so i'll take my time reading everything i can find well and learning by doing. I'm pretty sure that i can find all the procedures in here. Looking for a quick yes or no
Best Regards,
Daniel

as far as i know a sim lock has nothing to do with locked bootloader, s-on or s-off, root or not root, flashing custom roms.
so you can do anything you want without any difference. just follow the threads and guides, like you said.
btw. i think if you s-off, root and flash a custom rom you will loose your sim-lock anyway. but i
dont know which of these steps will do it
welcome and have fun
Is this a confirmed fact? The unlocking of the sim?
Always imagined it to be something quite deep in the phone, used to have a ZTE blade based phone that was unlocked by operator code... the moment i got back to stock rom the device got locked again.
I really am in blank of how sim locking works.
Thanks for the quick answer and the welcome

thats normal behaviour.
and i have red several times that flashing another rom will unlock your sim-lock,
i wouldn't give my life for it, but im more or less sure
and i DEFINETLY AM SURE that you will not gonna have problems while rooting etc. caused by your sim-lock. thats (again) for sure
I have always been under the impression that flashing a custom rom does not effect the sim lock, I have never unlocked the sim by flashing a rom.
Although I have now unlocked the sim by getting a code from ebay.

It's not a locked Sim, it's a Sim-locked phone, it does only work with one Sim
Sent my thoughts to your head with XDA App
so I am using ATT Skyrocket outside USA. The previous owner somehow unlocked it and then sold it to me. The phone is currently running on Gingerbread and I am planning an upgrade to ICS (i know how to do this). What I want to know is that after upgrade will the sim lock be reverted or my phone will remain sim unlocked after update?
please consider that it will be difficult for me to buy an unlock code so please answer only if u have tried or some expert knowledge.
thank you
I had my phone unlocked by kachman from this forum by a usb hack as he clamined. It stays unlocked no matter what rom you flash or upgrade. Also from cellunlocker.net, they claim if you unlock your phone using their code, you phone will stay unlocked regardless of what system you flash. It's hard to say if your phone will remain unlocked given the little info you provided. I'd say just stick with gb until you could get it unlocked again if you need to.
Your phone SHOULD remain unlocked. An OS upgrade should not affect that, or else everyone who gets their phone unlocked would have to bring it in/get a new code every time they did an upgrade, which doesn't make much sense. I Mean I can't say this with 100% certainty but I'd be a considerable amount of money that this is the case.
unlocking is permanent ....

will there were four parties involved in the middle before i got hold of the phone but when it came to me it was already unlocked and ready to take in any sim...now the point is that since its unlocked is it possible to find out how was it actually unlocked? and if it was done through an unlock code, is it possible to extract it from the phone itself? (some one has already payed for unlocking it so now there seems to be no point of keeping the unlock code in a secret location)

I just received my Sony D6603 Xperia Z3 from my carrier which is Rogers. Is there a way to fully unlock the device as if it was purchased as an unlocked version? I've tried searching for answers, but only came up with how to unlock the bootloader and rooting instructions. Unless, if by doing those methods, will fully unlock my device including SIM lock. Any help and insight would be greatly appreciated.
Depending on Roger's terms you should be able to have them unlock it. Appears you have to wait 90 days though.
http://www.rogers.com/web/support/wireless/unlock/733?setLanguage=en
Loving this one:
Why do I have to wait 90 days before I can unlock my device?
Your device has been optimized for use on the Rogers network. You may find that some settings or features do not function properly once the device is unlocked and in use with another carrier's SIM card. We want to ensure that you've had the chance to experience the full capabilities of your device on the Rogers network before making the decision to unlock.
Rooting and bootloader unlock will make no difference to SIM unlock.
The two issues are separate.

If I unlock the SIM on my device via a code, will it still be unlocked even after re-flashing my device's firmware?
Because I just checked to see if I can unlock my device's bootloader, but I'm not able to at all. Maybe I will be after getting it unlocked by Rogers themselves after the 90 days.

Please re-read what I said. Bootloader unlock and SIM unlock are two separate things. One does not affect the other. It does not matter what you do to one it will not change the status of the other.

Yes, I understood what you said. What I meant was, when or if I get Rogers to unlock my device, unless they're only unlocking the SIM on it, hopefully I'll be able to unlock the bootloader as if I originally purchased it unlocked to begin with. Because when I checked my device's service menu, the status on the bootloader is that it cannot be unlocked using Sony's official method. If I had purchased an unlocked device instead of getting it through Rogers, the bootloader unlockable status would be different, correct?
When I get home, I'll try and see if I can still unlock the bootloader un-officially using Flashtool, unless for some reason that method won't work at all and my bootloader will not be able to be unlocked at all currently.
Edit: All I basically want to accomplish in my new device is to have root access to it. My previous device was an Xperia PLAY which was also purchased originally locked from Rogers. But after fully unlocking it using the Omnius client, I was able to unlock it's bootloader, flash DooMLorD's kernel and get root access to it. Because all the tutorials I've found on how to access root on the Xperia Z3 involves having the bootloader unlocked.

Probably, but some carrier free devices come with a boot that cannot be unlocked and some devices that are from a carrier can be unlocked. SIM free or SIM locked does not imply the bootloader can or cannot be unlocked.

There is no unofficial bootloader unlock for this device. Its done through sony's official method or not at all.
If Rodgers unlocks the sim for you it will not affect the status of the bootloader at all, unless you ask them to do it and they agree.
To get root access you do not need to be SIM unlocked. The only way to gain root acces on the Z3 currently is to unlock the bootloader, which you cannot do even if Rodgers SIM unlock it
The xperia play is a legacy device and there were unofficial ways to unlock the bootloader. That has not been the case with all new phones for a couple of years now. I believe (Correct me if I am wrong) that the xperia NEO was one of the last to come with an unofficial unlock (The test point method). My old Xperia T was one of the first to come that had no unofficial unlock and the only way to do it was via Sonys unlock site.

That's something I didn't know, I've always thought that when you purchase an unlocked Android device that the bootloader would be unlockable, good to know!

That may be coincidence, I believe that Sony made a tactical decision to stop unofficial methods by allowing some devices to be unlocked officially. This saw an almost immediate stop in devs working on unofficial unlocks as you could always get hold of a device that could be unlocked officially and for free. They basically took the need of an unofficial unlock out of the equation.
If Rogers could do that, it really makes me wonder what kind of tool/program that they use to accomplish this.
Probably something similar to Emma or just fastboot and adb. I really do not know that. The problem is they know the keys, without them it needs a good dev to find a vulnerability and write an exploit. That takes time and skill. And since there is an official method there seems no need to spend that time, as people with that skill just get themselves devices which can be unlocked
My 3rd day now with my new Z3 and I'm really missing having root access.

Will SIM unlocking allow you to delete the Rogers apps?
Also, I noticed my phone doesn't let me hide apps, though most people seem to have that option... is that a Rogers thing or is there something wrong with my device?
Sim unlock has nothing to do with root, so sim unlocking will not give you the ability to remove system apps.

What i have done already to my device as soon as i got it, before even turning it on for the first time, was use Flashtool and flashed it with the Global Generic Firmware to get rid of the Rogers branding on it. I was able to disable most of the built in bloatware that originally comes with it.

Is there some sort of beginners guide/explanation/walkthrough you can point me towards? I've never had an Android before, so I have no idea what I'm doing and I don't want to screw anything up.
I'm currently with Consumer Cellular, brought my moto g from them. They have my phone locked currently and I can't switch to another carrier for another 3 months. My question is, does anyone know if it matters if I flash a custom rom, which will replace the factory rom, if it will prevent me from unlocking the phone when the time comes to enter the unlock code they will provide.
Asking because I don't know if the OS they provide when you buy the phone has any special features that control the operating of the sim card. When I try to boot with a different sim a window comes up asking for a code.
Thanks in advance.
Anyone?
I think you should wait. When you get the carrier unlock code, usually you have to dial a ussd code (starting with *#*# and ending with #*#*, or similar, you know better), then a code prompt pops up where you put that code. In other cases, password prompt comes up when you insert other carrier's sim. While I am sure that custom ROMs are designed with carrier locked users in mind too, but some glitches can happen, as explained here-https://www.mobileunlocked.com/news/does-having-a-custom-rom-affect-phone-unlocking/.
You can indeed unlock now, but if the custom rom doesn't ask you for an unlock code and the new carrier sim doesn't work (rare case) then you may have to flash to stock again. An US user can explain you in good details about this, I just pointed out what could happen as I we usually not have carrier locked phones here in Asia.

Good info, thanks. I did make a backup of my stock rom in twrp recovery, even before flashing twrp. Would that still be considered original stock software that I could reinstall if I did flash custom rom and it caused problems.

Yes. Nandroid backups are like system image backup in windows 7, they are virtual images of the backed up partition; so that wouldn't be a problem to restore these to get stock back.

When you insert a Sim from a different carrier, it should immediately pop-up a window requiring the unlock code, stock or not, to unlock the Sim... If it doesn't, you should remove the Sim, jump into recovery and backup, restore stock, boot and unlock, then restore the nandroid. Should be good to go. Haven't seen a locked GSM phone in the US the last few years that requires dialing USSD codes to unlock.

It just ask me for unlock code, via popup.
Yeah, we switched from Verizon to Consumer Cellular, which uses tmoble and AT&T. I had to buy the Moto from them because my Droid maxx was Verizon and CDMA. Anyway, we decided to switch to tmoble because we travel to Canada often and can use phone /data there. Got my sim from tmoble, put it in rebooted phone, then message pops up for code. Consumers don't tell you you have to be with them for 6 months. Phone was paid for upfront. If I had done my homework I would have just got a Google phone.
I don't believe there will be anything thing to dial, it just ask for network unlock code.
After I unlocked my bootloader, I booted into twrp and did a backup. Will that suffice as a stock backup? Also should the fact that I'm unlocked cause a problem?
Sorry everyone for the long post, but wanted to make people aware of the ends and outs of what can happen with different Carriers. I was under the assumption that all or most phones were unlocked.

Would be interested to know what part of OS handles this process. Or maybe it's commands on a chip. My thinking was its carrier related, so must be handled by the OS they installed on the phone.

It is a core OS function, not specifically carrier installed... There is just a security flag somewhere that's hidden and can be toggled with the proper code.

Well, I Have a backup for the rom on my device currently, and before anything has been done, except unlock bootloader.
Enough on this subject, going to go ahead and flash RR, the one that was taken over.
Again, thanks for all your insight!
This is an unlocked T-Mobile G5, but why have a special ROM for unlocked phone? I wonder if I flash other ROMs, I could lose the unlock. Anyone have any problem rooting and install twrp?
Conclusion after a month long discussion:
G5 with H83020i_un ROM is NOT factory unlock. Upgrading or downgrading will result in SIM lock to T-Mobile, period.
Once locked, it can only be unlocked by T-Mobile customers via T-Mobile unlocked app. Some has to go thru T-Mobile customer service and request SIM unlock by adding IMEI to their database.
I bought 6 (New to New other) unlocked H830 and 2 has the hacked ROM H83020i_un and 4 were completely locked to T-Mobile. Yes, those stupid sellers on ebay just keep sending lock phones as unlocked phone! Good luck getting a unlocked one.
No, you cannot install TWRP or root this version.
I ended up returning mine.
You shouldn't lose the unlock by flashing another ROM.
A ROM isn't just about 'locked or unlocked'. The ROM is the operating system. While it will still be Android no matter what you do, different ROMs are modified differently to provide additional features, or more control over the settings or just a slightly different user interface.
This has NOTHING to do with the phone being unlocked for use on any GSM network.
For example some people want to be able to control the CPU processor speed on the phone more. Some ROM's give you that control built into the settings and use customer kernels that allow the CPU to run faster than it does running stock. Other people just like a more simple UI that you get on base Android ROM's (rather than some of the overlays LG puts on)

Did you confirm that by trying the phone with a non T Mobile SIM on a different network? Or did you just let the T Mobile unlocker app tell you it's still locked?
The app isn't the most reliable thing in the world. It's known to say it's not unlocked when it is or that it can't be unlocked when it already is. Etc etc...
Unlocking it manually (through codes, ADB, root, etc....) messes with the unlocker app. But the unlock itself should still be valid.

The app isn't the most reliable thing in the world. It's known to say it's not unlocked when it is or that it can't be unlocked when it already is. Etc etc...
Unlocking it manually (through codes, ADB, root, etc....) messes with the unlocker app. But the unlock itself should still be valid.

I took the active H2o (At&t MVNO) SIM from my current device and tried it in this one. I could not make phone calls or access data, both in stock 20A and Resurrection Remix.

that's sucks.
I wonder if you can actually get an unlock code to unlock the phone now.

If I'm not mistaken, you can't unlock this phone with an unlock code.

I don't know when people will understand that it has nothing to do with sim unlock. I have T-Mobile unlocked sim lg g5 and flashed roms, custom and stock both several times and never had any problem with sim lock stuffs. Just install twrp, root, flash custom rom, there will never hurt anything in your phone.

Maybe it is something to the specific phones people are getting from the ebay seller. They are being sold as new yet are not factory sealed and missing the Tmo sim card. People are claiming Android pay doesn't work and the phone isn't rooted. A new out of the box phone shouldn't have that issue. So something isn't necessarily kosher.
Guys, I have the same version (H83020i_un) and it has April security update and T-Mobile has different version #s on their website. I have checked for update, but nothing came up. So I can't get T-Mobile updates?
The software version H83020i_un is apparently not an official ROM released by T Mobile or LG.
There is a lot of speculation on Slickdeals (a website for coupons and stuff where this eBay deal has been discussed quite a bit) that the unlock was done by flashing a modified ROM. If so that would explain why flashing a new ROM loses the unlock.
Additionally people are saying that Android Pay doesn't work on this phone with that software update, presumably because it's not official firmware. I've never used Android Pay so I have no idea if it works or not.
All in all if you have the H83020i_un software and bought the phone 'new' I think you got conned. It's not new and that seems to be unofficial software.
I spent a lot of time, with help from @autoprime, trying to figure out where the unlock is stored. I was able to dump the partitions from 20i_un using the method here. After I downgraded to 20A and flashed TWRP, I flashed back all the 20i_un partitions (besides recovery, cache, and userdata), and it still wasn't unlocked. So I'm baffled as to how the unlock works.

I see. It will be used as a second device, so it is fine. I flashed the phone with stock T-Mobile H83020a, then got few OTA updates. Now my phone has H83020i, but T-Mobile's page(below) shows an "f" version as the latest. So is the H83020i, the latest update or not? Also would be good if anyone with real T-Mobile unit could chime in.

And there is no way to root the phone without downgrading to 20A right?

So if 20i is the latest, then it is possible that T-Mobile's variant of the phone could have a different model # than H830...
