unlock (simlock) g1

Is it possible to unlock for free ? Couldn't find an manual (only jtag).

should I risk to buy an locked phone?

This has been covered elsewhere.
Your simlock can be removed by the service provider.
either that or there is a site out there that charges about £20 to send you the unlock code.
Ive just got a G1 off my cousin today and have suffered the same. Luckily for me he is still a tmobile customer and should be able to get the unlock code from them for free.

Thanks for your confirmation (wasn't sure about this).Jtag can also be done (but thats madness)

Just another question:
I've read that the locked version uses different gsm networks(dual band), while the unlocked versions use quad band.
Can an locked phone that has been unlocked use the quad band (with the right radio) too?

Anyway I've bought the google phone

I found that unlocking on ebay is the fastest and the cheapest way of doing this.
BTW: the phone I'm going to buy has already CM 4.6, should I root again after every build I flash (the kaiser builds were always rooted) ?

I wouldnt have thought you needed to root again if it already has the Cyanogenmod on it as i think its already rooted.
im still learning the android stuff!
i do know that within 3hrs of having my (still locked to tmobile) "virgin" G1 i had the Danger-spl and the latest release of CM on it!
ebay i will have to look into as i have discovered that because im in the UK Tmobile will charge £15 to unlock even though my cousin has had this phone since release.

Simlock has nothing to do with the rom, and a rooted rom has nothing to do with the simlock outside of prompting you for the code if the radio firmware tells the rom its needed to proceed.
There is no reason to unroot/reroot besides increasing the chances you make a mistake and brick the phone.
If you want a different rom that's your choice, but it will have no impact on the simlock.

So after flashing a custom rom (phone was already rooted) , the phone is still rooted?
Reroot is only needed when flashing the original image back (if you want a custom rom later) ?

Sim unlock code is best to unlock the HTC G1,But free unlock code is not possible to get for this Model Phone,You need to pay for it,Get the unlock code from the site Superunlockcodes.com/htc/rs12wp8/ and Unlock it.

Best unlocking site

Hi I want toget my phone unlocked which is the best
Sent from my GT-I9000 using XDA App

which model do you have?
i9000 is not locked
i9000m is Bell locked

Hi Samsung Galaxy S i9000 im on t mobile uk, i heard before i flash new firmware i need sim unlocked before use.

the uk models are not locked

thats strange because i put o2 sim card in my phone and it ask for simlock code

where did you buy the phon from?
online or in Orange kiosks/stores ?

T-mobile shop

ohhhhhhhh i see now, it seems like T mobile locked their releases.
keep in mind, those are not the same models as the USA Tmobiles

so i cant flash new firmware from samsung.firmware.com

yes you can flash, but the flash will not unlock the phone
you don't need to unlock the phone to flash a new firmware

[Q] bootloader unlock allowed - no

I have a T-mobile uk Arc that has been network unlocked using Octopus SE.
Unfortunately when I go into the service menu it still says "Bootloader unlock allowed - no".
I though that unlocking it from the network might have changed this.
Is there anyway to unlock the bootloader and/or root the device if the bootloader unlock says no? i tried re-flashing using the namaste guide, but it didn't work.
I really don't understand why this is the case though. What is the determining factor for the bootloader status?
(sorry i know there's a few questions here but i'm so frustrated from having no look in researching this)
Thanks for any help you can offer!

In the service menu if your Bootloader Unlock says no then you cannot UNLOCK it.
The only way is VIA TEST POINT method (which carries RISK of bricking your device) can be done to have unlocked.
You can still HOWEVER root your phone. Cheers mate.

First of all thank you for the quick response.
I unlocked my phone from its network using the testpoint method (using Octopus Box). Is this the same as what you are referring to or is it a method of re-flashing that uses the testpoint?
Thanks!

If you done it correctly "TEST POINT" method your Bootloader should be unlocked.

Hold the menu button, plug in your phone.
If the LED turns blue (fastboot mode), your bootloader is unlocked.

You now have a unlocked phone, not a SIM-FREE phone. Only a SIM-FREE phone that was never sold via a network will come with a unlockable bootloader.
It's why these sell for a bit more (£30ish).

... he's already said he unlocked it from the network. Therefore, he does have a SIM/network free/unlocked phone.
However, SIM/network unlock is completely separate from the bootloader.
If the Service Menu says bootloader unlock is not allowed, you need a paid tool like SE Tool to unlock it.

Perhaps it's a regional terminology thing.
In the UK, unlocked means it was once locked to a network (but usually still with network branding)
Sim-free, means it's totally unbranded, not sold with a contract and not sold by a phone network. ie. totally independant of any phone network.
Only Sim-free is unlocked bootloader.

I agree with you, I don't think they really understood exactly what you meant.
I remember Rikard from the SE Blog when they announced about bootloader unlocking on the new xperia phones. He also said that phones with generic firmware will be allowed to unlock bootloader.
So just because, you have unlocked a phone from t mobile it isn't a Sim free phone.

I have to be thankful that my actual carrier doesn't do sim-lock.

First of all, thank you for your contributions.
So to re-cap, it is a T-mobile branded arc, that is now network free, but not sim free.
Is it possible to flash the phone to make it sim free? Would would using SETools acheive this?

Ugh. SIM and network are the SAME thing: locked to a specific carrier / cannot use a different carrier's SIM card.
The bootloader is different. Generic (unbranded) phones have unlockABLE bootloaders through a FREE process. Carrier-branded phones ALSO have unlockABLE bootloaders but the process is NOT free.
Any bootloader can be unlocked, regardless of SIM/network status. I suggest you watch the video and pay attention to the FAQ.
There is no firmware or software that you can flash onto a phone to SIM/network unlock it. Buy an unlock code or tool credit (Omnius, SE Tool, etc.).
There is also no firmware or software that you can flash onto a phone to unlock a bootloader. Either use http://unlockbootloader.sonyericsson.com or pay to get it unlocked.

Thanks for the answer but CrazyPeter is right. There's a regional terminology issue here that is not not translating.
That being said it does look like SETool is the way forward. I should've checked exactly what result unlocking with Octopus box would have.

Contact Jinx13 who will be able to unlock and open bootloader
I had sim locked three phone he did mine Sunday and it is easy and quick

Thanks cheify009. Heard his name being mentioned a few times now.
If u don't mind me asking, was it expensive?

Good morning to all! I have a big question! I have a Sony Ericsson Experia ARC vodafone brand new and comes with android 2.3.4 compilation: 4.0.2.A.0.62, and when connect it via the PC COMPANION tells me there's a new update 4.1.A.0.562, should I update it?
I've seen in many forums that updating the phone slow down the performance and assure me I'll regret of that. the other thing I was thinking is to make a backup of my original rom, but there is some way to make a backup of the original rom if something goes wrong? with the update? thanks

Understanding flashing

Hi guys,
Just bought a galaxy s5 from my uncle who worked in Canada, the phone was locked to Telus Canada I unlocked it through unlockBase which was superfast and easy.. I have now really started using this phone and have now realised that the date format is different to what I usually use, I have done some research and found that an update stopped the ability to change it to prevent blackmarket sales or whatever.. I was thinking can I just flash a uk rom on the phone or not? But will it relock the phone? Also will rooting the phone enable me to change it? Although I don't wanna root because my online banking app won't work or WhatsApp?
Thanks in advance guys

This is definitely one of the strangest reasons for rooting...
But since it's a Telus phone its definitely a G900W8. You can cross flash all and only G900w8 firmwares so i.e. you can flash Rogers on bell, wind on telus, sasktel on koodo, etc

Thanks for the reply, yes rooting was the last option as some apps won't work.. so if i was to flash it i would only be able to use telus firmware which is US could I flash a UK firmware on it? And if I was to flash it would it still stay unlocked or will it need reunlocking?
EDIT: done some more research.. will changing the csc code on my phone to one of a uk firmware, then installing a uk firmware work?

Nope because anything outside of Canada uses a completely different phone model and flashing between different models will likely lead to a bricked phone (phone is damaged unrecoverable)

Flashing stock firmware on carrier locked phone

Hey everyone! I'm somewhat new to XDA (as in this is my first time creating/posting a thread) but I've decided this is the best place to get some help.
So, I have a carrier locked G935W8 Fido phone, and I was wondering if it was possible to install the stock G935W8 firmware from sammobile. I have read around that flashing the stock firmware works after the phone is unlocked, but what if it is still carrier locked? Can I still flash the stock G935W8? Or will I brick my device? My phone is not rooted btw.
Thanks to anyone that can help me out!

Welcome to XDA
yes, you can flash stock firmware as long as it is for the locked carrier.
Other firmware will work but the imei maybe effected.

Well, that's the thing. I want to flash the unlocked Canadian firmware, as in the one with no carrier bloatware. Will that be possible and have the phone working 100%?

I'm afraid I don't have an answer to your question, but I just did the carrier unlock on my new G935W8 a few days ago using basically the first website to come up in a google search. $25 USD; waited about 18 hours to get the code. You don't have to rely on your carrier (with their insane fees and/or waiting periods) to unlock your phone; might as well just do it. Having an unlocked phone is very handy if you travel at all.

yes, it will work for most things 100 %. volte may not work as it requires a carrier branded firmware.
you will probably have to enter the number for your voice mail manually and settings for internet as that is in the carrier branding.

Thank you everyone for your help! Just a question, what do you mean by settings for internet? As in data/LTE?
