System Updates Questions

I just purchased a unlocked my touch 3g ( I believe Magic) no slide.
At times my phone asks me to do a update.
When I look at what the update is it shows "Android System Update 1.2...The system is required to install Android version 2.2.1 on your device."
My phone states my firmware version is 1.6
So my questions are:
Do I need to perform this update?
Will this update lock my phone again ?
This is my 1st android phone and truthfully I'm not real technical. I have been going around googling different thing to make mysel more familar with the phone and Android.
Any help woul sure be appreciated.
Thanks in advance
Ok so 81 views and nobody knows.
Anybody have any idea what other sites out there may deal with this type of thing that they may be able to direct me to?
Thanks
Could you please provide the info on your fastboot? You can get to fastboot by turning the phone off, then turning it on while holding down the volume down button.

I hope this helps and what you were asking for
Thanks
First off, you do not need to update if you don't want to. Second, I think the update will relock the phone, so I recommend not updating at all, unless you have a reliable method of unlocking again.

I appreciate the info
Ok there are two things:
1) Sim Lock.. if your phone is sim unlocked it will remain sim unlocked.. actually I don't think there is any documented way to re-sim lock the phone.
2) Root.. if your phone is rooted i recommend installing a rooted version of the upgrade if you desire to upgrade.. otherwise the upgrade will either unroot the phone or fail because the phone is currently rooted (possibly causing it not to boot into android until you restore a good firmware)
Remember the sim lock is different from root.. and you can be rooted but sim-locked... or sim-unlocked but not rooted.. the simlock is just the tie in to the carrier and part of the Radio.. not part of the android firmware. Further its in a special radio settings region that is not flashed when you change the phone's radio.
So if you have the stock un-rooted/un-modified firmware and wish to update feel free.. just note you may want to back up what you can first.. some people have had problems with the update going slow until they factory reset after the update..
ezterry,
Thanks for the info.
Truthfully I'm unsure about many things on this phone.
I purchased this phone off Ebay as a unlocked only phone.
When I received the phone I just popped in my sim-set up the phone and was done.
At this point though I'm not even sure its unlocked because it is a T=Mobile phone and my service is myfamily mobile,which is just T-Mobile sold at Walmart.
I put in a sim card from my neighbors AT &T and it asked me for a pin #.
I skipped putting in a pin and the phone opened up but said no service. With that I am just assuming it is truly unlocked.
Am I correct?
Um.. if it asked for an unlock code its locked.. if it was sold unlocked and showing the code you ought to have been provided the code by the seller.
Pin usually just means the owner of the sim locked put a pin on the sim to prevent it from its data/service being accessed by others. (The sims owner ought to know the pin) This pin needs to be entered into any phone the sim is put in.
As soon as I find another person with a different sim card I am going to try it again.
I do think it was a pin # that was asked.
Unfortunately the owner did not provide any sort of code when I purchased.
Its my understanding,and I may be wrong,that you can purchase unlocked phones new,and if so I'm not sure weather or not codes are provided for new phones.
This is all very new to me so I am not sure.

If a HTC Dream/Sapphire was sim locked at the factory you must put in a sim card from another carrier and unlock the phone.. If it was never locked (such as the Google versions of the phones) this is not needed.
Once Sim Unlocked it will remain so regardless.
Yes, this is a My touch 3g google version phone

MT3G = T-Mobile = locked to T-Mobile US but running the Google firmware
ION = Google Development Phone = factory sim unlocked

So does this mean the phone is not unlocked and can only be used on T-Mobile?
or
Is it possible someone paid a 3rd party for a code to un-lock it?
I guess I really need to try like a AAT & T sim and see if I could service,as that was my undrstanding. I was under the impression that any gsm service provider uising a sim card would be operable.
You have gone in a circle now.. I told you if its sim locked when you put in a sim of a diffrent provider it will ask for an unlock code.. once sim unlocked it will *never* be locked again.
You will of course need a non tmo-us sim to be sure.
All I know is the MT3G will have been shipped from the factory locked.. I will not know the current state since the seller prob made sure it was unlocked if it wasn't already so if the phone was sold unlocked ..
The only other way I know to test is harder to do and possible risky with the firmware changes to do it w/o special htc serial wires.
And FYI a pin protected sim will ask for the sims pin before the sims carrier can be read (thus you need to provide the sims pin before it will ask for the unlock code if the phone is sim locked)
Ok,gotcha.
Sorry,told you not to savy
So I'll test another sim again and see what happens.
Thanks again for all the support

Ok.
So I pulled the sim card from my neighbors AT &T phone and when the phone booted up it asked me for :
"sim network unlock pin"
unlock
dismiss
My neighbor told me he didn't have a sim pin,but he used the code he has to lock his phone.
I received the same message when I tried someone elses sim who also states they have no pin number.
Message being: "Network Unlock Request Un succussful"
So am I correct in my thinking that this phone is not unlocked? and or it is sim locked?
I just e-mailed the seller asking him if he had the unlock code for the phone,so I can now only wait for his response. In the past he was not very responsive to past e-mails

samsung galaxy S4 unlocked asking for SIM network unlock pin

Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio
If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.
Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.

S7 Edge permanently locked to AT&T network (Too many network unlock code attempts)

S7 Edge permanently locked to AT&T network (Too many network unlock code attempts)
Hello all!
I've moved to Korea with my fully purchased AT&T S7 Edge (SM-G935A) from the U.S. I went to a local authorized phone service shop in Korea and purchased and linked an SK Telecom Nano USIM 3GB data sim card to my phone and then entered in too many unsuccessful network unlock code attemps. I wasn't aware that if too many failed attempts are entered, that the phone would lock permanently to AT&T network :/.
I then contacted AT&T and got the official authorized network unlock code, but that isn't working. Neither did the unfreeze code I purchased from an unlocking site. I then found the XDA forum and successfully flashed my phone to G-935U (http://forum.xda-developers.com/att-s7-edge/how-to/updated-935u-935a-live-links-pi3-t3501686). After inserting the prepaid Sim card, I'm still receiving the network unlock code screen where the AT&T network unlock code, unfreeze code, and codes on Sim card packaging are not working.
Can anyone advise any solutions? Is there a way to reset or get around the hardlock / permanently AT&T network lock?
Thank you,

I have had hard locked phones before, here's how you can get it fixed. If its still under warranty, and if you can get it to samsung usa, tell them your phone is stuck due to a bad update. They will reflash your phone, and when they do this, with their methods, it restores the modem firmware and the original sim's lock(no more hard lock). & they will reprogram your imei and serial. So your unlock codes will work now.

network unlocking 6p

hi, i just got my (second hand) nexus 6p and so far i like it alot.
updated to 8.1, unlocked the boot loader, installed twrp amd magist to get root all working fine.
the phone seems to be locked to vodafone (uk) as it works ok with a voda sim but when i try a ee sim or 3 uk sim it will not register on the networks and says emergency calls only. the thing thats confusing me is that it does not ask for a unlock code when i try another network sim, every other phone i had has always asked for a code to unlock it. am i missing something or is there another way to input a unlock code if / when i get it from voda or a third party unlocking provider?
cheers / thanks
You might be right but the solution is there check out this page https://support.vodafone.co.uk/Usin...one-device-if-I-m-not-a-Vodafone-customer.htm
thanks to a message from Exodusche my problem is solved. the phone is not network locked at all, when changing the sim for some reason i had to turn off the security pin then reboot the phone and as if by magic after that i had service and everything working fine. some sort of glitch in 8.1 i guess.
