CyanogenMod - in a vanilla or official build - will not typically contain a bootloader. On many devices there is really no good way to even overwrite the bootloader because it is on protected memory (the bootloader is "locked") and cannot be overwritten. It installs a boot image and a system image (i.e. writes to the /boot and /system partitions). I've heard ...

Yes - all android devices will work without a SIM card, and can be connected to wifi for an internet connection. EDIT: Just so people know, there is a setting in the build.prop file that determines whether or the not the device can be used without a SIM or not. Most of the time this is set to allow it, however in rare cases it may be disallowed.

Normally unlocked phones are unlocked for good. I wouldn't expect a factory reset to change it. (See also: Unlocked Galaxy i7500, Reset Will Remove it?) It's not 100% certain, though. For example, some Galaxy S users had their phones re-locked when updating from 2.1 to 2.2, which is a somewhat similar process to doing a factory reset. You could always ...

The SIM lock stuff is in a separate ROM chip that is not part of the normal phone storage, AFAIK. It's manufacturer/device dependent. Definitely nothing to do with the baseband (and you can certainly flash other basebands).

No, rooting your phone will not let you use it on other carriers. If you have a good standing account with tmobile, and I believe you have to have been a customer for like 9 months (or something like that), you can call them and tell they you are going out of the country and want to be able to use an international sim card. they will give you the code you ...

Finally solved it.. I have found this ansewer by yy502 on cyanogenmod 1) you've missed the PIN prompt when phone starts up. no phone calls. 2) go to "location & security settings" 3) go to "set up SIM card lock" 4) un-tick "Lock SIM card" 5) enter your PIN as required 6) your phone will now connect to the mobile network. full bars!! 7) re-tick "set up ...

Some Android devices, mostly older ones, and CDMA2000 devices, will attempt to let you not use them without activation. Usually the 'provision' application has a secret code that can bypass the 'mandatory' activation - e.g., on the Motorola Droid 2 Global it's upper left corner, upper right corner, lower right corner, lower left corner (the lower corners ...

Yes, it works fine for me without SIM-card. I can still use WiFi for accessing Internet.

This differs from carrier to carrier. Some will be sim-locked, some aren't. You'll have to ask your carrier. It has nothing to do with the OS.

No, CyanogenMOD and other custom ROMs rely on your device's bootloader. In general you don't want to mess with the bootloader since doing so is an easy way to brick your device. The bootloader doesn't really have anything to do with the SIM lock usually. I don't know of an Android-specific way to unlock this phone, which means you'll probably need to use ...

No, the bootloader has no bearing on a SIM/network lock. The HTCdev site explicitly states this on the bootloader unlock page, in fact: Please note that unlocking your bootloader does not mean that you will be able to unlock the SIM lock. Unlocking your SIM lock is at the discretion of your operator/carrier and is not part of the bootloader ...

No, they're completely unrelated things. As you say, an unlocked device means it's not locked to a particular carrier: you can insert a different SIM card to change to a different carrier, and it will work. A locked device will not connect to another carrier if you change the SIM card. The bootloader is the first thing that runs when you turn the phone on: ...

You should call your carrier in the UK and explain that you need to unlock your phone because you are travelling. Unless they're being particularly unhelpful a carrier will normally give you the unlock code for that purpose. Edit: It looks like the unlock code may be stored on the device and accessible as with many Galaxy phones, most easily if you are ...

See this thread on XDA-Developers Unlock Motorola Droid Pro: You simply call Verizon and tell them you're going to spend some extended time in Europe and you want the ability to unlock the phone and change out the SIM card so you can use the phone as a local phone without all the charges, etc. They'll then tell you that you won't have the ...

If you have an unlocked phone, I don't think there should be any problem. The SIM card for GoPhone is apparently just a regular prepaid SIM card and is not tied to the phone it is sold with. If the phone doesn't recognize the APN for 3G, just go to Settings > Wireless and Networks > Mobile Networks > Access point Names and enter the appropriate ...

Generally speaking, rooting is completely unrelated to unlocking. CDMA unlocking is also more difficult than SIM unlocking a GSM phone, and CDMA phones need to be activated on the network, unlike sticking a SIM in an unlocked GSM phone and doing whatever you want. You'll need help from both carriers (Verizon to unlock, your carrier to activate) in order to ...

Unlocking a phone from network has nothing to do with manufacturer updates. Its more of, being able to take a SIM card from another network and pop it in. For example, buy a handset from Orange, and using a T-Mobile SIM card in the new Orange handset, the T-Mobile will not work as the handset is locked into the Orange network and thusly refuse any other ...

The phone specification says it supports the following frequencies: 2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100 I think this is almost all the frequency, so the phone should work in India.

If the SIM card works, and you can get a network signal, then the deice is unlocked and it is a different error that is stopping internet from working. It could be due to a number of reasons that internet isn't working, I am going to list them: Invalid/Wrong APN's APN (Access Point Names) allow your device to connect to mobile internet. You nust ensure ...

You don't use adb to connect to a device when it's in the bootloader menu: you need to use the fastboot command instead. That's why it's called "fastboot mode"! Not all phones support fastboot: in particular, older HTC phones use a proprietary protocol called HBOOT instead, but I think the newer ones support fastboot.

If your SIM card is PIN locked, the network unlock code is useless. The network unlock code allows a phone that is restricted to a single carrier to be unlocked for use in other carrier's networks. The SIM PIN is a personal identification number that is used to unlock the SIM card in order to register it to the network. This means that the phone will not ...

I have an HTC Sensation 4G that originally was purchased from T-mobile. I unlocked it using the code provided by T-mobile (free) and used it on AT&T. I just did a factory settings reset as instructed in the user manual and it still works fine and is still unlocked.

Don't mix things here. From your posts it looks like you have entered your SIMs PIN to often and need now to enter your PUC/PUK. This has nothing do to with your androids phone lock. In Germany it's common practice to receive the PUK together with the SIM card. If you have no PUK you can only ask your SIM provider for the PUK or a new SIM. I am not aware of ...

The Galaxy S2 has an unlocked bootloader, which means you can install any rom on it, rooting is not mandatory, some roms have root privileges, some don't.

According to the FastGSM page: "Congratulations! Your phone is permanently unlocked and can use it with different network SIM card. It will never relock again even if you do software update." (source) This means that even a factory reset won't relock the phone. I assume this is because Samsung phones use the /efs partition to store the IMEI and other ...

You'll need to purchase an unlock code. You will probably find a number of companies via google a I have used a couple, which I'm not sure I'm allowed to post here so I recommend you visit Modaco, the site run by Paul O'Brien of custom rom and rooting fame. Click the Android part of the site and at the bottom of the site or via a web banner to the right, ...

According to AndroidCentral and these XDA posts, the Photon 4G is specifically made to prevent access to AT&T or T-Mobile and an unlock code won't do anything. Presumably so that if you are in the US and don't need to roam away from Sprint, you can't switch away from Sprint. The limitation doesn't appear to have been hacked around yet.
