[Q] How to SIM Unlock without unlock code?

hey..
my LG P500 Optimus One with Froyo 2.2 is sim locked in Vodafone RO, and won't accept other service providers.
Is it possible to unlock the service provider without generated codes using IMEI?
VODAFONE charges 40e for unlock code (and others, about the same price), and i bought the lg for less than that, on a 2 years contract.
rooting and installing custom fw will unlock my lg?
please help. thanks in advance.

In this thread guy needs help "How to enter unlock code" into his device. If I tried enter this code, my original FW from LG said me, that is not possible do that, because of "Device is not customized". So, I think, that flashing of original FW can unlock phone.
On other side - operators can lock phone in their network based on IMEI and because IMEI is not changed during flashing, it's possible, that id will not work.
I would like to test it for you, but I haven't locket phone. Here are sellers not allowed to sim-locking their devices.
//Edit:
I just readed some stuff around and it seems that this information is stored into GSM Module firmware.
Here is Czech thread (google translator) were guy trying to solve sim-locking. I just posted him PM if he have somewhere on net how-to manual for do that.

thanks..
it's simple to enter unlock code (just call 2945#*500#) and it's simple to get unlock code for about 30$ ) that's not what i'm after.
i think it's foolish to pay 30$ for a code to unlock a phone which i paid about 40$. (why did i make a 2 year contract then...?)
interesting stuff those cz guys try. ill be watching that thread..
PS: i officialy hate google for not implementing proxy settings :|
I don't think your going to unlock your device with a custom firmware. In the others Android's LG cells, it wasn't possible.
There is a "simple way", you can try to find an app that allow you to remove the battery to swap your sim card. There was one for the LG GW620.
You can also wait to buy an cheap unlock code on internet, or a "Magic Sim" (I'm not so sure it's going to work, but it's 5 bucks).

swapping sim is an interesting idea..
i tried it with no success. you don't need an app.
it's true, if you remove the battery the phone restarts, when plugged in.
but if you keep android "busy" he won't restart (i kept my finger on the screen and slided between pages while i removed the battery and swapped the sim)
no luck the phone doesn't say service provider locked like when i restart with the simcard in, it just doesn't register the network "Emergency calls only".
The lockscreen says "no SIM card"
it doesn't change when i swap again with the original.
thank's for the tips..
i'll dig up on magic sim. see what's that about.
Same here.
Would really like to find a way to network unlock the P500.
Paying the phone's price all over again isn't fair.
Not having root access isn't fair either, but security comes first.

Thanks god that in our country doesn't exist any kind of this stupid thinks like operator's network locking. It was prohibited by law.
It is really hard to find some tool, that can this do. Especially if this stuff are stored in GSM module. You need special technique and resources to reach goal.
Hi everyone,
I'm a newbie with smart phones and a newbie with the P500... hens "I don't know if what I will say applies" in unlocking the phone.
A funny thing happened to me the other day - the phone was charging in the USB port of my computer - it was not in "removable memory" mode. The computer had to be rebooted and I forgot to unplug the phone from the USB port.
Guess what... I had no more service after rebooting the computer - had to call up tech department of the cell company. They made me manually choose their company in the settings menu. Don't know why but the cell phone company info was "unprogrammed" after reboot.
So as I said - maybe this will give you guys (who know more than me for the moment) a lead to finding the solution of this thread's question.
Cheers !

Salut. Si eu sunt roman, am avut telefonul blocat in vodfone si ma intrebam acelasi lucru.
Hi im from Romania too and i used to have the same problem. I sent the phone to a knone cellphone hacker from Iasi and he unlocked my phone for 30 lei (around 10 bucks).the phone had a lot of that vodafone bulls*** with vodafone default homepage, vodafone app for i-dont-know-what and romanian android menu.so after i recived the phone from that guy it was unlocked.but i think he might flashed a new OS because my phone was empty, like new ,and i loosed the default romanian language.,and it was having a newer version of sofware on him.it was like a neverlocked phone xD.So i think if you will flash another rom, like that one for europe in your case ,i think it will unlock your phone.oh yea ,and that bastards from VodafoneRomania asked me for 50 euros !!!!! I i'ved unlocked it for around 10 euros ) .

So bad for the SIM swapping, I was using an app to avoid the cell to restart, and It was well working on the LG Eve GW620. But after, LG has given me a Free unlocked LG Optimus (here in France, LG has posted a news to give Free optimus one. I was just asked to fill a long form to make a review between the Eve and the Optimus).
Something good to do would be to ask someone to monitor using adb the functions used when unlocking the P500 using an official networking code.
Did any one to free unlock a LG P500 locked on Vodafone RO ???
I know that there is a GSM Unloking Tool called Vygis that can unlock this phone by flashing it with a unloked firmware...but I don't have it.
Any other options???
I too would like to share my experiences with locked phones.
My Lg optimus one was locked (untill last week) to a spanish mobile provider (movistar); at first i tryed to flash an unbranded firmware, then a custom rom but with the same result: locked phone.
The reason for this is that unlike certain "dumbphones" which can be unlocked via s/w, my Lg was locked through imei. In these cases there are only two solutions(some one correct me if I'm wrong), ask the mobile provider to unlock it (not always possible) or buy un unlock code online.
I used the second method, it cost me just above 10euros and it was realy fast.
Havent had any sort of problems what so ever and now i can use any sim card.
I've bought my P500 for 620 RON (145~150 Euro) form o guy from the internet (a site similar to eBay but only available in Romania),new, not used, already unlocked, with LG Warranty (not Vodafone Warranty, even that i've got the full pack (phone + silicon/rubber case) )... And Yes it was blocked to Vodafone network, but that guy unlocked it in same price (something like a bonus)...
I'be bought it from here: hxxp://www(dot)okazii(dot)ro/catalog/51741498/lg-optimus-one-p500.html
This phone can be unlocked in services, for around 9~17 Euro, but I'mnot sure about the Vodafone Warranty, you might lose it ...

Or you can go to Big Berceni or Obor, but people from these services are sneaky/greedy, usualy say a price after they look at you...
replace hxxp with http and (dot) with .
Overall is a great phone, great OS, great hardware, great battery life ... the only downside is the lack of Flash.. and I don't mean Flash 10.1, but it doesn't even have the Flash Lite 3.1/4.0
Hi all.
Please tell me what happened with phone after 10 unsuccessful attempts entering unlock code? my phone - optimus T P509
seller sended me not correct unlock code and i have 1 attempt to unlock my phone.
Sorry for my bad english

2945#*500# doesn't work on my phone. i am using CM7 Rom by Mik
I came across a site which is selling LG unlock code for €8.00 but i don't know how to enter the code.
And also when i insert a sim from different network, it doesn't ask for unlock code or doesn't even show that my phone is restricted. Only says no network. Is that because i am no using LG branded rom?
I took the phone to a unlocking shop and they said they could unlock the phone by connecting it to a computer. By changing some firmware details. But i am not too sure about this. I am using Mik's rom and i don't want them to change anything around. I have custom recovery installed and i little afraid about this. And i am also afraid that after they change the firmware will i be able to flash new ROM? and if i flash new ROM will that lock my phone again?
So if you guys have any idea, please share

Need a quick answer regarding SIM cards

Hey guys, I'm new to the G1. I just picked a used one up the other day to use over seas. I reset the phone not knowing I need a SIM in there to actually use it. I don't have access to a SIM card currently, but I will have one when I go over seas. Will the phone unlock so I can root it with a SIM card from a different carrier? Or do I need to have a TMobile one in there? My plan leaves tomorrow early morning, so I'm kind of in a bind when it comes to solving my phone issues.

Oops, I thought I posted in General.
The sim card from n e where will work for the rooting process so don't stress that. These instructions will get u n to the phone with out the sim card. http://theunlockr.com/2010/01/10/how-to-activate-the-g1-without-a-data-plan-or-sim-card/
Good luck!

If the phone is locked , you need to get it unlocked first....otherwise it wont use any other network sim other than t-mobile.
The easiest way to unlock it is to call t-mobile and ask them for unlock code by giving them IMEI number of the phone (can be found in the MENU--->SETTINGS---->ABOUT PHONE----->IMEI NUMBER)
They provide the unlock code for free.
Once you have it unlocked, then whatever sim you insert, you will be asked to enter the unlock code. Enter that code and phone will start using that sim.
If you dont get it unlocked here from T-mobile then get it unlocked from the country where you are going...but the charges and success rate of unlocking depends on which country you are going to.....it is very easy and cheap in South Asia like India and Pakistan.....but difficult in Middle East.....
So the best alternative might be to buy a cheap GSM phone there and sell it when you return here.
Have a happy and safe journey
Thanks for the help everyone. Unfortunately, Tmobile couldn't give me an unlock code since I'm not their customer. I've got some more digging to do. I came across some sites offering the code for a fee, are they legit? I just don't understand how they get the code when I can't.
Go to ebay and buy it. for abt $6.49, they will give the code to you. I unlocked mine via ebay... Try any seller.
Based on timezone, buy from US seller or your local seller to get it quick.
Like for US try http://cgi.ebay.com/UNLOCK-CODE-T-M...025?pt=LH_DefaultDomain_0&hash=item1e5f205f99
Make sure u provide them your IMEI code.. dial *#06# Or look under battery.

It works but you have to know what you're doing with it. Did you contact Tmobile for unlock code. We unlock and blacklist repair the Sprint, Tmobile, etc. The Tmobile ones have to go through that app during the process

yea man i called...they sent an email with instructions.. email stated this phone doesn't require an unlock code as it has a built in unlock app. follow the directions below blah blah balh
bottom line, it doesn't work. why? because there's hidden rules and crap that need to be met 1st by t-mobile. prepaid people need to spend at least 100 dollars in refills before the phone is eligible. post paid people need to have the phone active on t-mobile for a minimum of 45 days and your account cannot be cancelled during that time.
well seeing as how i'm on prepaid... i walked in, made a new customer purchase as a post paid user, then cancelled my line after i got my gear vr and netflix code... which wasn't even 30 days. I can't unlock my phone, So I'm now on prepaid gonna see if I can after 100 dollars in refills

I use ebay to get my unlock codes, unlocked maybe a dozen phones in the last few years and never had any issues with anyone.
A couple reliable sites I've used many times are www.unlockbase.com and www.cellunlocker.net . There's also a thread over on the s6 general forum of a member named stifilz that can unlock your device via USB cable, his service is free but a donation is always a nice gesture. Good luck!

kinda ridiculous you have to pay to get an unlock code still. My SM-G930FD i bought unlocked locks itself every time in install a T-mobile csc and the app wont even run on that phone
Hi can anyone help? I bought an At&t S7 Edge on amazon and got the unlock code from the vendor and it apparently worked. My only issue is that it'll only work with the sim that was in the phone when I entered the code. If I use another one the phone keeps displaying "insert sim". Thanks already for your replies
Thanks for the reply and there's 1 more things I need to mention: I'm using the phone overseas (Haiti) as it's still under At&t contract. Now to answer your questions no it doesn't ask for the unlock code anymore but like I said it only works with the non At&t
sim I used when entering the unlock code.

s7 (sm-930f) lock to Austrian A1 was not able to be unlocked by unlockbase.com. However, the nck from cellunlocker.net worked well.
Ok so what im mentioning is something im still not getting quite well, but i saw before many samsung phones S6, S7, Note... etc that have the international firmware 9XXF/FD even when the phone is actually a T-Mobile version or AT&T, in download mode you will be shown the real phone model but the firmware isn't. Of course through Odin with a PC you won't be able to flash the phone with a firmware besides the one designed for it. If you actually wanna flash the phone you'll need the original firmware, i tried it before and flashed a Verizon S6 that had the international 6.0 firmware on it through Odin and as you might guess i got an error as the device didn't match the firmware, when i actually flashed it with the correct Verizon 7.0 firmware it worked and the phone booted and worked alright, except that now the phone is network locked! downgrade isn't possible unless i use a repair firmware and a pit file (not sure if still works with nougat). Then i got the idea of actually using the repair firmware and the pit of the 9XXF version as its network free, and ended up breaking the phone completely. The jig didn't work so couldn't access odin. So i work for a friend of mine in a repair workshop PC, Consoles, Mobiles... blablabla and we have the Z3x box, it did unbrick the phone, and then i started playing with it to see what it can do, and there is an option to actually flash and mix different parts of the firmware, so i went an flashed the bootloader of the Verizon firmware with the rest from the international firmware, it didn't boot at first but somehow i got it into recovery mode and after a format it did boot, and the network was actually unlocked after.
I do not think this method would work on all versions, as some samsung phones uses the snapdragon soc while others uses the exynos soc, and i don't think you can mix those firmwares, but an unlocked exynos model might be unlockable with the international firmware, of course considering the risk of breaking the phone, but if you're lucky as i was and have one of those boxes you shouldn't be much afraid.
Something else i'd like to mention, is that the Z3x can actually fully backup the phone, and i don't mean a nandroid backup like TWRP but like a full partitions backup, and the idea i got but didn't test is if you have for example a locked S7 and an unlocked one and same model so let's say 930P, you can actually copy the raw partitions from the unlocked one to the locked one and i don't know, maybe ending up unlocking it too, again didn't test this one as i only have one S7 and its already unlocked (930FD).
