Can an ulocked G1 be locked by upgrade or root?

If I have an unlocked G1, can anyone tell me if I root my phone and update to some of the firmwares posted hete (RC33), is it possibel that my phone becomes locked again? I now have RC19 and the phone is fully unlocked, but I'm afraid it can become locked again if I root it or flash it with another firmware. I have enough technical background to do the rooting and flashing as I have expoerience with windows mobile, but this is something new for me. Btw - i totally love the G1 and regret not leaving windows mobile.

The Sim-Lock is in an area of the phone that can not be "flashed' by the user. You are good to go!

Thanks a lot for that !

I have been looking for this answer, as well. I have a brand new g1 that I traded my 3g iphone for. It's unlocked and on my AT&T account with no problems. But I had my iphone modded to the hilt and so of course I want to do the with the g1. That was the answer i was looking for!

Anyone else?
Yes. Please, anyone who has rooted and upgraded their UNLOCKED g1 , share experience. It may seem like a stupid question to some of the "advanced" users
bt remember - you weren't born with knowledge, so share it!
For example - an ulocked Iphone can be locked when upgrading so are you sure that the G1 won't lock as well!

What do you mean unlocked? As in sim unlocked, if so it can not be locked by upgrading software.
If you mean unlocked as in you have access to root. Then yes, but that is why you use JF's firmware.

alright ive got a rooted rc33 and im on at&t, ive upgraded from rc30..
so even when you upgrade you're good to go

I mean sim unlocked
I mean what unlocked means - SIM unlocked. My device is rc19 and came unlocked for any sim cards. I haven't done anything with it yet - root or upgrade and I wanted to ask if it's safe root and upgrade a sim unlocked device.
I was concerned it may become locked again because I don't know anything about the unlocking process on the G1 - I know there is a code that's generated according to the IMEI and tahat's about it but I wanted to know if this code can be erased by flashing newer firmware. I have read the steps described on this site for root and upgrade and I plan to do those with my device but I wanted to gather some opinions first. I hope this topic will be useful to others who have bought the G1 unlocked and are concerned.

youre safe to upgrade and root, ive done both and mine has stayed unlocked..

Ok. That sounds encouraging. I recall that there were more than one ways to unlock the Iphone. Is it the same with the G1 - I know the main way to unlock
it is by entering a code but I also know there are HARDWARE unlocked devices (as the developer edition of the G1) - Is yours only simUnlocked or is it hardware unlocked too? I'm sorry if I'm asking too much, but I don't want to pay 30$ to get an unlock code again.

It's not like the iphone. The iphone is has to be 'unlocked' by hacking the firmware, since apple have never released any legitimate way of unlocking it, and seem to take great delight in re-locking 'unlocked' iphones every couple of months (this is one of the reasons why my iphone sits at home gathering dust).
The G1 has a standard unlock code, just like just about every phone on the market. Once that code has been entered the phone is unlocked permanently. There's no such thing as a hardware unlocked device - it's merely never been locked to a provider. In the same way if I buy a 5800 from Nokia it's unlocked but it's no different to one got on contract, it's just never been locked.
Google don't care much if you run JF firmware or something you cooked up yourself... they give away the source code so you can do just that.

Thanks.
So entering the simunlock code is irreversible process, having nothing to do with the firmware. That's what I wanted to hear. Thanks guys.

Successfully rooted, upgraded to Jf RC33 with multitouch, put apps on SD and very happy now

[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.

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

Motorola Unlock BootLoader

Is it possible to unlock flipout from this website ? https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-b
Also is there any custom rom for it ?

No, the Unlock My Device program at the moment supports only one new device, the Photon Q 4G LTE.
I really hope that the masterminds at Motorola will soon add many more devices, especially older ones like the Flipout. Many of these devices are out of warranty by now anyway.
As for custom ROMs, there are none. Unfortunately the Flipout was not very popular with the modders. However, with an unlocked bootloader this could change.

So... how does one 'SIM unlock' this phone?
Do I understand right, that it needs to be rooted first?
Do I need to also CID unlock it, or is that only needed for flashing a custom ROM?

Only way for BF/Charm is by code, does not require root. Check ebay: search for "unlock mb511" or "unlock mb502" - fairly cheap these days,
Actually, bootloader unlock and carrier/sim unlock are two different things, so we're rather off-topic here.
I'm sure Moto has no interest in unlocking bootloaders of phones they've already sold, so in response to the OP I should say, "No; absolutely not; not ever."

bootloader unlock allowed: No with factory unlock SIM

Hello everyone.
Yesterday I bought my Z1 factory unlock SIM in a store. The box with the phone was perfectly sealed. Anyway, the first thing I wanted to do is unlok the bootloader. When I try, I realize that getting into the mobile me menu appears bootloader unlock allowed: No.
I have contacted Sony and they say I need the SIMlock (number of unlock) and of course this does not have it and the operator said that neither does.
This may be so, or have cheated me in the store and sold me a mobile unlok for them?
What I can do? No way to get the number SIMlock?
Thank you.
Greetings.
PD. Sorry my bad English.

I think you getting confused. SIMlock have nothing to do with Bootloader.
SIMlock is a SIMlock from you provider, that means if you brought you phone from Vodafone, you can use Vodafone Sim only from them on your phone. But like I can see is not your case because, like you said, your phone is SIM Unlocked, that's mean unbranded.
Bootloader is that part of you device which allow you to flash your phone or root it. In your case if there is Bootloader Unlock Allowed: NO, that mean you can't unlock you bootloader. There is no way to unlock it. And you should search on XDA first.
Link: http://forum.xda-developers.com/showthread.php?t=2576948
What you can do with Locked Bootloader;
Root your phone, Flash Custom or Stock Roms, Flash Stock Kernels.
What you can't:
Flash Custom Kernels.
For the rest of the part search on XDA.

Hello, thank you very much for responding.
The concepts have very clear, I come from a Xperia Z I bought right out. I had understood that to unlock the bootloader has to be mobile factory unlock or unlock if you have the attendant need to contact Sony to enable you to unlock the bootloader.
That condition must be met in order to unlock the bootloader with the traditional system?
Like I said it quite well how this works, I've had HTC's. The problem is that without the bootloader unlock AOSP I forget which I love. :silly::silly::laugh:

Just check could your phone be SIM unlocked and if yes - order SIM unlock number from Internet.
There's million web pages and you'll receive your code in a day or two.

The thing is: people are reporting that this "bootloader unlocking allowed: no" is done by the operator/carrier, in my case, Vodafone and they have means to change the "status" in order for it to be enabled. I've read reports of other xperia users saying that through the official support channels it's possible to send the phone to Sony with the SIM-unlock code and they'll unlock everything.
Also, in Portugal theres a new law implemented in 2010 that goes like this:
You can always unlock your device from the operator: if you're on a contract, you have to pay the remaining months entirely. If your device is at least 2 years old, you don't pay anything.
If you're not on a contract, you pay the difference of the unlocked-version price with the price you paid for locked-version device - say, I paid 250€ for my locked Xperia L, the unlocked xperia L at the time I bought mine costed like 279€, i'd have to pay 279-250 = 29€ to unlock my device.
Also with this law, there's a National Communications Authority (ANACOM) which controls everything related to communications in Portugal, I'm going to contact them and report this "double lock" that's being applied by Vodafone, because I'm pretty sure that, if I unlock my phone, they're forced by law to remove every restriction on it.
I don't lose anything on trying to fight back with everything I got so... that's what I'll do.

This is something what clarified the situation. So this Lock on bootloader is done by the operator and there is a Double Lock on the phone Z1, SIM-Lock and Bootloader Lock.
And both can be unlocked?
But what have SIM-unlock code to do with Bootloader?

That's what I'm not sure. The SIM-lock is the basic thing the operators do in order to prevent users from switching to another one, but now they also apply the bootloader-lock in order to prevent users from installing modified-unnoficial software.
Sony might request the SIM-unlock code in order to "prove" that the phone has been released, thats my best guess. I don't really know if it is somehow related to the bootloader-unlock. But since it is a restriction applied by the operator, once I request it to be unlocked, I literally asking for the full access to the device... which can only be obtained by unlocking the SIM and unlocking the bootloader

It has nothing to do with the bootloader unlock!!!

I bought my first Z1 phone (i've got it replaced under warranty) branded and sim-locked, but the bootloader was ALLOWED to unlock.
So - i think sim-locking and not allowing the bootloader to be unlocked, are two DIFFERENT things.
p.s. - however, i think it's worth trying that request in Portugal law. There's nothing to lose.

Bootloader Unlocked: You can flash Custom Kernels, Bootloader Locked: You can't flash Custom Kernels, Stock Only but you can flash Custom Roms and be rooted.

Well. I gonna tell you what i did in spain. I got a Phone from movistar with the status to unlock bootloader set to "no". I ask to my provider for the sim-unlock code and I got it. I sended to sony an email "[email protected]" requesting to change this status. To certified that my phone is free i add the sim-unlock code, my imei, phone number and device model. After a week or two they answered to me with this:
In connection with an inquiry number 1-9......., we inform you that we will proceed to pick up your phone for the release of the bootloader of your phone.
For this we need you to contact us by phone to ask for the information needed to program the day of collection of the terminal.
Our phone hours are: 902 180 576 Monday to Friday, 9 to 19:30 hours uninterrupted.
Once you receive your terminal you will be able to unlock the Bootloader and make the process of "unlock" the bootloader, this operation could void the terminal as shown in the web http://unlockbootloader.sonymobile.com

My case
In my case, I'm survieving with a HTC Wildfire S because Sony has taken my Z1 to change from "NO" to "YES".
Mine was from Vodafone and after SIM-Unlocking I realized I can't unlock bootloader. I contacted Sony in Spain and they asked my about my IMEI and NCK code (SIM Unlocking code).
A week later they called me saying that they would pick my Z1 to "unlock" it and 3 days ago they pick it up.
I miss my Z1.

Urko

Yes, what happens once I unlock it clear and I did with my old Xperia Z.
What is not clear is I have the phone in order to unlock the bootloader or not based.

I hope you succeed in getting an allowed bootloader-unlocking phone.
However, i'm curious if Sony will return you such a device, with the same IMEI as you originally had. Please keep us informed about that.

I hope not to have to send it to Sony. If I can not solve this surely return the phone and buy it somewhere else.

Hi.
I had a bootloader unlock allowed: no Xperia Z5. From my experience you cannot unlock it at all, for love nor money.
Did you happen to buy it from Sony directly or buy it from a carrier (Vodafone, 3, EE etc)? As if you bought it from a carrier then it is impossible to unlock it's bootloader. If you bought it from Sony then you need to change bootloader unlock allowed to yes in the developer menu in settings.
Hope this helps

Hi.
Open settings, scroll down and press system, press about phone, scroll down to build number and press it repeatedly until it says you've unlocked the developer menu, go back to the last menu, press advanced, then press developer options. Around the top quarter of the list there should be OEM bootloader unlocking.
Best of luck
