Do I lose the sim unlock when upgrading - Android Software/Hacking General [Developers Only]

Find contradictions on this item.
My Phone seems to be unlocked when I had Android 1.5 on it. When I switched it on I got the message I could upgrade to Android 1.6
Now it is asking for a network unlock code. So it is locked. Is this due the offical 1.6 upgrade or was it already locked on v1.5 which I basically couldn't test back then.
I never rooted this device, nor put alternative rom on it nor did anything "special"to it.

No, it should not. If you still have the unlock code you should try it.

[Q] Unlock Code

I'm Just wondering If I update to 2.2 will my phone lock again or once it's unlocked it's always stay unlocked even if i do a hard reset >?
I haven't updated to 2.2 yet so don't take my word, but I've read that it re-locks and disables the easy way to find the unlock code.
But, if you write down your unlock code before updating to 2.2 and then enter it again in 2.2 you're good to go
Definitely save your unlock code somewhere so that you can re-use it if it re-locks. My phone has gone through JH7 update then Froyo update and stayed unlocked. But others do claim theirs get locked again.
Regardless, your unlock code should be the same because it is sololy based on you IMEI number.
so, is the general consensus that once you're on JH7 you can no longer get the unlock code? or did i miss the 'how to' thread for that?

JH7 is still 2.1 ROM and it is still possible to get the unlock code (a little bit more efforts than stock JF6). 2.2 ROMs are impossible to get unlock code as far as I know.
The following is pure speculation---feel free to object
It *may* be the case that, once the official Froyo update is rolled out, an unocked phone will stay unlocked. I assume that somewhere in the internal file system is a file that keeps track of the network lock status of the phone. The unofficial JI6 ROM may have been an image or backup taken from a locked phone; in this case it makes sense that the network lock will be restored upon flashing that image. But, in an official update, this may be avoided.
On the other hand, I have seen posts mentioning that not only was the phone relocked upon flashing JI6---the old unlock code itself was apparently rejected! I find this both puzzling and worrisome: I do want to upgrade to Froyo when the official update arrives, but I also need my phone to stay unlocked.
BTW, I updated to JH7 OTA and the phone stayed unlocked.

Ive got no issues with a little more effort – just not quite sure how to go about it. Would you be good enough to either fill me in or direct me to a thread where i can figure it out?
Thanks!
I have flashed my phone a few times - JH7, JI6 (2.2); and now back to stock with JH7.
My phone is locked and the original lock code dos not work.
According to a post on Cyanogen's forum - I can take the existing stuff in BML3 file:
SSNV´'šù..Jøý.—.~n.•öVÚðÜž|.hÿ6*§ÒùF....Gmñ.¾E.¸Øoß’.Öµ.†.ˆì..Á.ñ-*y!96Ý.FFFFFFFF........................00100100101#31015031017031118031041031098099999#
And replace the FFFFFFFF with my 8 digit unlock code and push this file back to the phone.
Has anyone tried this?

My phone stays unlocked even after JI6 flashing. I have no idea why others get locked again. Maybe they never unlocked properly when they were still using 2.1 ROM.

i had this problem with 2.1 rooted when i put in my non att sim card, asked me for the unlock code again, go to this to get it unlocked the msg above
i updated my firmware to 2.2 froyo rooted thanks to senior member last night and it never asked for the unlock code ever again
Save your unlock code!
Every time I've flashed a new ROM I've had to re-unlock the phone. Supposedly other people have not had to re-unlock, so it sounds like a case of YMMV.
I had my phone unlocked and working fine overseas. Got back could not wait so put froyo on. I thought the unlock would stay it did not. But i had the codes so no worry. I tried twice the codes from before but they did not take. So going to get a cheap tmob prepay sim and try that did not want to kill my other good sim. I will let you know how that works. If any one has any ideas please let me know.
Edit: got brave put it the sim from Japan again after flashing cog beta 4 and did not ask for unlock code. So i guess it works,somehow. Ill still get the tmob sim tomorrow and try. But looks good now.

[Q] Please help me unlock my LG G2 D800 32GB locked to AT&T

I purchased LG G2 D800 (32gb) locked to AT&T network. I wanted to unlock it with a code and tried various webstites - 3 of them replied that they cannot offer any support, 2 emailed me back with an unlock code. Codes from those 2 different websites were the same, however it did not work - I now have the last attempt left to unlock it. I tried through one of the 'shops' as well, but they couldn't help either. Can you please advise if you have a reliable way of unlocking or obtaining a code for unlocking? Is there any other way to unlock this phone? Maybe at least a way of bringing the count of tries back to 1? I also tried ringing AT&T but they could not help, as I did not have an account with them - I'm stuck.
Thanks for any help or suggestions you may have,
PLEASE HELP!:crying:
hi guys, I still waiting for your answer... Please help me!:crying:

Thanks a lot for the advice. My phone wasn't rooted (I checked with an app) so I think its runs original rom (and it's Android 4.4.2), Baseband Version M8974A-AAAANAZM-1.0.190082 Kernel Version 3.4.0 Build Number: KOT49I.D80020c Software Version D80020c
I have the last try (10 out of 10) to put a correct unlock code. Have you got any other suggestions? Do you know how to change the number of attempts of unlock back to 1? Thanks

I would honestly say flash a completely stock rom...go back to square 1 with it. find the AT&T stock image. flash it back thru the LG program. then try again with the unlock code. its possible the previous owner just flashed a stock ROM to the phone. does it have stock recovery on the phone or CWM or TWRP?

if you have'nt unlocked it yet try this ste i got it done for $1.9 the cheapest ever http://www.unlockcode247.com
Apologies for not writing back sooner. I only have 1 attempt left to put the code in, so I am reluctant to try another website, since 2 did not work.
I am worried I will lock the phone indifinitely. Does anybody know how to bring the count back to 1, so it was showing attempt 1 out of 10 for putting the sim lock code in? Thanks

Rogers D6603 Full Unlock

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.

Has anyone unlocked AND used a Custom ROM after?

Hi,
I need to unlock my device and my guess is I need to go back to Stock for the Tmobile Unlock App to work (does this even work in the first place?). So my question is has anyone used this successfully and also rooted/flashed another ROM after the unlock and it stayed unlocked?
If there are things I need to avoid after a successful unlock, please let me know that as well.
Thanks!
interesting
Well I know my N5 is unlocked under stock rom. After flashing a custom rom I lose the unlock. I've posted in other threads about this but there has not been a good answer other then getting an unlock code which I don't know how you would for tmo. But flashing an intl custom rom will let you get to the menu to enter the code to unlock. The question though is how and where would you get an actual numerical unlock code for a tmo device? Cellunlocker and a couple others I've contacted are not able to get an actual code to use for the tmo N5.

Sim unlock solution developmet for T-Mobile S7 G930T

Hello everyone
Here's my problem and my idea:
I bought T-Mobile Galaxy S7 on ebay about a week ago (Stock QC1 firmware) and now I'm in need of sim unlock, which I can't, my device's unlock fails every time through Device Unlock app
I've searched through the web past two days and found no solution whatsoever. Every service is down for now and I cannot find any ways to unlock my phone.
So, here's what I thought: Maybe here's someone who can actually develop or figure out a solution for this since many solutions are available for S6/S6e and many other t mobile phones, but not for S7.
I can be tester and provide any files/dumps if needed or anything you guys ask.
I believe I'm not the only one with this problem and if we try hard enough, we can do this. Many people can benefit from this also, so let's be useful.
To mods, if you believe this is a wrong place to post this thread, please move it where it belongs.
Thanks to you all.
So your idea is just to look at other device solutions? [emoji1]

We probably wont see a direct unlock solution on these T-Mobile/MetroPCS QUALCOMM based Galaxys for some time. The older models you mentioned are Exynos based CPUs, they are being unlocked all the time. Unlock app or trusted server for imei unlock is our only solutions for now.

Factory reset your phone, then try to use the device unlock. You can select temporary unlock or permanent unlock. Once you are done you will have a sim unlocked device.

Actually, MetroPCS s7 & s7e device unlock is available for $20 and Qualcomm S6 and below is also unlockable, there are many remote unlock services on ebay/various websites for those devices.
I've been* trying to unlock my S7 since April but no luck.
I know this issues with t-mobile Quallcomm Galaxys are about locked bootloader but that's the only thing I found out.
If someone can make bounty pool or something similar, I would gladly participate.

Yup. I'm on android 7.0. I could go back to 6.0.1 too. Why do you think this is a method to unlock? You need to connect to Tmobile database to unlock. Merely factory reset won't do anything. It's all in the cloud

I know, however when I had issues with the device unlock app a fresh install of the latest version worked and I was able to temporarily unlock for a month.
I did it just now after a factory reset, rooted and running no BS Rom...

I went through the same ordeal. I had to actually call t-mobile and get a representative to unlock it using the phone's IMEI number so it could be used on all carriers. Call them, I'm sure they will unlock it for you. That t-mobile unlock app doesn't do anything. Also under developer options, you need to check OEM unlock before you call t-mobile.

Called them maybe 10 times, even used their facebook page. Every single customer representative said phone is fully paid and nothing is blocking it but they can't help me because I'm not actual / original phone owner on their database, and person I purchased this phone from has no idea what unlock is, he's impossible to deal with. Maybe you have any tips for me?

I think you and @boobteg have a paid off devices eligible for unlock. What you need to know ow is that the device unlock app doesn't work on custom roms. It requires a stock rom. There are some of us who are not eligible for unlock.
Any progress?
none so far
Same Solution
Hi! im having the same problem, i cant unlock my s7 tmobile with device unlock app, every place i try say it that the service is down. II flashed with the g930U, now the smartphone ask me for an unlock code, there is anyway to find that "unlock code" to unlock the phone in this way? Or maybe installing an non stock rom is possible to unlock the phone?
Help!! i cant use it in my actually country
