Question about Acer Liquid Z520 Network lock - Android Q&A, Help & Troubleshooting

My friend asked if i could help with his phone. He recently got a new sim card and found out his phone is locked.
Everything on his phone is the way it came out of the factory, nothing has been change... So, for all info on the hardware just google 'acer liquid z520'.
While searching for a way to unlock it, i stumbled upon these sites: http://www.tntts.com/2016/07/open-line-acer-liquid-z520.html & https://www.phcorner.net/threads/230676/
Is this really a way you can unlock the phone? I never saw this kind of way, I thought you needed to unlock bootloader and/or flash some new rom...
Tried searching for a similar thread, did not find anything, sorry if i missed something.
If this is not a legit way to unlock this phone, please point me in the right direction. He would like to avoid paying 20$ to unlock it and waiting for another year for the contract to end is also not an option.
Thanks for the help.

[Q] Problems with SIM Unlock

Hey Guys,
Hopefully someone can help me out since I can't seem to find answers anywhere to my problem. I got an unlock code from T-Mobile but when I put a foreign sim into the phone is says "invalid sim, 0 attempts remain". I got the phone on craigslist so I'm guessing whoever had it before me tried unlocking it with the wrong code too many times. I have the right code now, how do I reset the attempts? I can't believe that the phone is hard locked and there isn't anything I can do about it. It's pretty frustrating so any help would be appreciated!
Thanks!!!
really???? no one knows anything about this issue?
So people here know how to put different operating systems on phones but no one knows if it is possible to reset the sim unlock counter?????
the phone is hard locked and (certainly in most cases) can now only be unlocked by using a hardware unlocker. (for most phones, you get three attempts via the keypad, and a further 10 via a hardware connection normally.)
thanks for the reply! what exactly does hardware unlocking mean? would i still need to use the code given to me by t-mobile?
speak to a phone shop (or better yet speak to t mobile first)
have you tried to restore the phone to factory(not a hard reset). I would try going to Tmobiles website and try to update the rom...

^is for US phones I just did mine today because the guy that put android on it removed the unlock screen and I was unable to unlock the phone. And no one on here was able to answer any questions for me so don't feel bad.
Got it unlocked last night! turns out the sim card i was using was locked. i tried a different one and it let me key in the code. thanks for all the help!
now that the phone is unlocked would doing a hard reset lock it back up?

good stuff. No, flashing / hard resets will not ever lock the phone now.

[Q] Unlock Sim

Hi everybody,
My sister came back from Canada with her phone and she didn't ask for unlocking it (I don't even know if they would have done that for free., but....)
I told her, "no problem" I can do it. On my HTC just rooting the device did the trick!
On the Hero, even a goldcard seems to be useless.
Am I right?
The only option is to pay a site to give the code (I found unlock now .com that does it for 15€). Has anyone used this here?
It's a telus / canada HTC Hero and I wanted to be sure that someone has done something like that with success.
Thanks for anyone who will answer!
Edit : I found a process here, but I need cable. Anyone in Paris?

[Q] sim network unlock pin

Hello everyone, this is my first post here and I am in need of desperate help.
I have looked everywhere I could but (my bad) I am not into all this stuff at all. I am not familiar with ROMs Kernels etc. I just follow tutorials blindly.
I have a galaxy s2 bought which I bought in the UK. It was locked on 3 network. Later I moved to another country where I got it unlocked for about $35 but that still showed signs of 3 network (The 3 startup logo, 3 bookmarks in web browser etc), however the phone was unlocked now and picked up any network I used.
I noticed the phone stopped giving me any kind of updates and it was on andriod 2.0.1.
I looked up the internet on how to install latest updates for my phone.
Found out this guide and went thorough all the process: goo.gl/yJSga8
Everything went fine but when the phone booted up, it asked me to enter "sim network unlock pin" and now all networks are inaccessible.
I am pretty much stuck at this point. Found guides telling to root the phone and then installing apps like Galaxy S2 SIM Unlock by Chainfire.
I have tried it once and was near to kill my phone. (The yellow triangle appeared at startup and got stuck there. No boot.) I just re-flashed the firmware by following the first guide again and now the phone is like before asking for sim network unlock pin.
I have attached the screenshot of the info that you might need.
I am willing to pay $15 via PayPal if anyone can help me out to fix this issue. (I am a bit hesitant using the rooting method as I an afraid I might kill my phone. But if that's the only choice then I will go with it)
Please ignore if I sound really stupid as I really don't know about this stuff. Please ask me any details that I may have missed out.
Thank you very much!
Attached Info Screenshot
If you don't want to root, then you'll have to call your carrier and ask for an unlock code. Mine has that service at least, don't know about all carriers.
As far as solving your problem goes if your carrier won't help out... The thing that works for a lot of members here is to root, then use galaxsim unlock app, by xda member spocky12. Search for the thread.
That app requires root access... To do that, easy way is to flash philz kernel from recovery mode. Search up philz kernel thread here on xda and read up how to flash it

Hello hopper, thanks for the response.
I took your first suggestion but instead of calling the company itself I used an online service unlockliberty.com.
They charged me $20 via PayPal and almost instantly sent a code to my email address.
I entered the code on the phone but it gave me "Network unlock request unsuccessful" error.
Contacted support and they sent me a defreeze code and instructed me to restart, enter the defreeze code instead of the unlock code and then it will say "Network unlock request unsuccessful" and after that enter the unlock code. I did the steps and it worked like a charm! my phone is now unlocked.
I really recommend their services if you are in a similar situation.
Thanks alot!

[Q] Device Lock

Ok first off I'm sorry if I'm place this here I just didn't know what section it should go in.
Heres my problem I have an old alcatel onetouch 4010a that my mom wanted me to fix for her and It started to fail. I tried restoring but it couldn't
so I had to use a custom rom. Let me go back a little i had to pay to get the phone sim unlocked a few months ago and with this new rom it says enter sim me lock. Do i have to pay again? I looked around alot already and cant find anything this is my last oppstion. Please help if you can.
Thanks
They only did some dirty hack to unlock your simlock. I'd go to the place where you got that "simlock unlock" and DEMAND that code from them or a refund.
If they won't do it then buy that code from somewhere online or try to find a generator for your device. Keep in mind that after 5 failed attempts your device will get locked forever. So you should either go to the place you got your "sim unlock" or buy a code online.

The LG L52VL from ST/TF

OK, So I purchased this LG Treasure about a month ago and of course. I'd like to root it, Problem is Tracfone has this thing locked down tight. the bootloader/Recovery is not accessable. If you do the volume down/power button combo, it only brings you to a Factory date rest option. . I went to LG support and had a chat with them. I was informed by the tech that the bootloader access has been disabled. I asked if there was a way to enable access and he said that there is a way but he is not allowed to tell me and suggested that i come here to inquire. So i am hoping some here might be able to help, I don't even care if brick this device , it's worthless as is. Adb will see the device but fastboot will not leading me to think it's disabled by the carrier as the tech suggested. So any help would be greatly appreciated. Some one please point me in the right direction with anything i can try . Thanks All.
thank you..

Thank you so much for posting this question as I have that same issue. Your question was well put. Yet no one has responded. I hope there is a solution to this issue. :good:
these questions regarding the rooting of the lg treasure, which is my phone ironically, brings us to 1 definate answer, and that is that tf already knows how to unlock the bootloader, and thus, root the phone. it seems logical if any other tf/st phone has a similar os/locked bootloader that has been rooted, we might try those, or find someone recently seperated from the employment of tf who may spill the beans perse. just my input.

Thank you for giving me some hope lol. But still I have had no luck rooting this phone. Pretty aggravating. It's a decent phone and all. Sad they ruin it by locking it.
oem unlock
Did you first go and turn on oem unlock in the developers section of the phone? It is required by many phones under loli to unlock the bootloader. Might need to turn on usb debugging too in order for fastboot to be able to access the bootloader to get root on the phone.
My OEM unlock option has been enabled. However I have had no luck at all rooting this phone. It's unfortunate. Again I'm asking any developers available to please work on this project. The LG treasure is a very popular phone. Not only because of the price, But the features the phone has. Please I have done my best getting this phone to root.. But I'm out of ideas.
I have the lg rebel 2 lte and same problem. There is of course a way, their official unlocking policy is they'll grant us the unlock after a year of service paid. So they charge you for the device then charge you for a whole year for full access to said device. $$$
But lg has an official developer thing now where they'll email you the unlock.bin file to unlock it.
However the only; and I can't stress this enough, the ONLY problem is they've coded the bootloader to skip fastboot entirely. Somewhere between the first and second splash screen the bootloader and fastboot are working, soon as it shows the tracfone logo that's when you know its booting android. I have yet to figure out how to read the logs of the boot process to see how.
Yes, enable oem unlock and usb debugging.
However everyone with a new lg phone under any of the tracfone subsidiaries will find that those options don't matter. There must be a dialer code for the bootloader deal.
