Any way to check when the phone was made - LG Optimus L9 P760, P765, P768, P769

I recently got a hand-me-down P769 and I wanna unlock the bootloader, but I can't remember when the phone was bought or made. Is there any way to check?
Also, if I unlock the phone and/or flash a rom or kdz, do i have to reactivate?

There should be a date on the back of the battery, for most people, if the date is past July/August the odd's are the bootloader is encrypted. Although its not definite because I seem to be encrypted on an phone that was bought in April, and I've seen people unlock on a phone with later dates.
Try and find out. Also by reactivate I think you mean reactivate the sim which will not be needed. Good luck!

The year on the battery reads 2012, so I guess I'm golden. I tried to unlock it before but no luck, probably because I didn't have a sim card and data yet.

I flashed the 20b rom, but now I have no service, even though i had service with the 10g rom (using the noob guide)
edit: I got the service to work by flashing the radio.zip but now when i boot I just get told that my phone is being encrypted. I went into software mode to try and start over but now the lg software won't recognize the phone even though my computer recognizes it fine

[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...
http://dl.htc.com/ruudownload/t-mobileUS/DeviceDownloads.aspx?pid=leo
^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?

[Solved]Help me delete data

Hey everybody,
I just got the x10 today and I've never hacked a Sony so I know nothing about it right now, so forgive my ignorance.
The phone was used and didn't come with a sim card. I've put 2 different sim cards in it that I know are good, but when I boot up it gives me a sim card error and only let's me make an emergency call.
I'm thinking that because his data is on it, it needs his sim card? I have always had cdma phones so sim cards are new to me also.
My question is... Is their a way to get into some kind of boot menu by a button combination at startup or something, where I can delete the phone data?
Any help is appreciated.
Edit... Phone is stock, not rooted, yet

How would that happen? The phone is legit, no outstanding bill on that account and its not stolen. Are you saying I need his sim card to unlock it so I can use another?
Just to give you more info, when the lockscreen comes up, it says "sim card is faulty" but if I hold power and select airplane mode, then turn off airplane mode, it let's me past the lockscreen and then I get a toast box that says "sim is not provisioned mm2"
The phone was on at&t when it was used. I don't have an at&t acct. For now I just want to learn about it and root/mod it. Maybe ill call at&t.
Might be another issue :
Some anti-theft antivirus programs are able to lock your phone for your sim-card only (to prevent using another sims when phone is stolen).
If its set as device-manager, it also cant be disabled (requires some password).
So, try to boot up your phone without SIM card ant check this first. If device-manager is not set, then your phone is surely simlocked.
Thanks for the reply, I've tried booting up without a sim card and it gives me an error that no sim is installed and will only let me make an emergency call.
I called at&t last night and the rep asked me to hold the menu + return buttons while pressing power and I should get an option to hard reset the phone. That didn't work so she patched me to Sony. They had me download Sony pc companion and sent me instructions to "repair" it.
He said it was 1 of 2 problems. It's a "software glitch" or a broken sim port.
If the repair won't fix it, ill have to send it in and for $185 they'll fix it (yeah right). When I get home ill try the pc companion. This phone is in mint condition and was fully working before the guy that gave it to me went to an iPhone.

Might be both - hardware malfunction or simple simlock. Personally expect simlock. My phone is not simlocked and when turned on it can run without sim card simply as PDA.
Try to flash your phone with generic WWE ROM and try again. Or before, check if phone doesnt have usb debugging on.
Afraid that no, but try to look with flashtool or adb (if yes, we can make full wipe within xrecovery)

If its sim locked then I'd think that I could use the previous owners sim to get into the system, right? Then how do I sim unlock?
I can't check for USB debugging because I can't get past the emergency call only screen.
I've got the pc companion downloaded on my working phone, when I get home I a couple of hours I'm gonna xfer it to the comp and run it, hopefully that'll fix it. If not, ill wait till Monday and get the previous owners sim and try that. If that doesn't work.... I'm gonna get the night vision goggles back that I traded for this phone, lol.
Running this phone without a sim is exactly what I want, just as a pda. How'd you do it, or better yet, what it called, sim unlocking? I can look for a guide, but I don't even know what its called. I feel really dumb about this phone, sorry bout that, if you came to the evo3d forum I could give you all the help you needed.

OK then If you want to use your phone as pda, without gsm or data connection, then the simpliest thing you can do is to flash stock generic ROM (you dont have to care about baseband and so on).
However you need to do a sim-unlock first because otherwise it will be still locked on the operator. Heart about many unlocking methods on websites, eg. this one (really expensive):
http://www.mobile-unlocker.com/sony-ericsson-xperia-x10/rs2wp9/
Never tried (always buying phone without sim-lock).
What operator is your phone locked?
YOu probably have to google about your exact operator locked version, hopefully you will find unlocking code or online service for it.
BAM! I got it, thanks for all your help. I used the pc companion and chose repair, I lost all data but that's ok, I was gonna erase data anyway. When I boot up it still gives me a notif that the sim is not provisioned but I can still get into the system.
Time to start hacking away at this thing, I've got a lot to learn I'm sure. I downloaded flashtool and it says it'll root so I'm gonna try that. I'm open to any more help you can give out, you probably think that some of the easy stuff is common knowledge but even the smallest stuff will help me get started. I'm gonna start reading in the sticky section, thanks again for the replies.
Also, after the repair, I have a different lockscreen, it looks like an iPhone lock kinda. Before, I had the lock that went up and right on a curve kinda, how do I get back to that one?

Now i understand why you wasnt able to get into system without sim You were on old android 1.6 which was default OS when X10i was released. But there were two big software updates - 2.1 and last year our beloved 2.3.3.
Thats why you have different lockscreen. In 1.6 it was shaped like half-circle, in 2.3 its just a simple horizontal slide... But there is not any solution how to get this lockcreen back as I know. BTW.: Also liked the old one lockcreen
Everytime you will need a help, post and we will surely help you !!

Ok, I'm starting to get it now... My system info says
Firmware version 2.1-update1
Baseband 2.1.65
Kernel 2.6.29
So far I've rooted, installed xrecovery and unlocked the bl. All the roms I've looked at say I need a higher baseband to use that rom. Can I use the pc companion to update to 2.3.3, and is it gonna cause an issue since I have a custom recovery and unlocked bl? The reason I ask is because on an LG I had, it would brick if you did an official update with a custom recovery.

I recommend you to use Flashtool intead There are problems to get the ftf file with generic ROM, which also includes .71 baseband which is surely needed for any custom ROM. But I think this is simplier solution. If you want active link to FTF bundle I will post it (also with guide, already wrote it for another users).
You can also use PC Companion, and it surely dont affect your phone in any way. If you rooted it and installed xrecovery its surely not problem (I performed this once on my device). Dont know about unlocked bootloader (dont have it and dont want to have it ), but think thats also not problem.
You can brick X10i only if you flash kernel and something unexpected happens (cable unplug etc...).

Got it, I installed DiXpreia 7 'avenger' using xrec for Rom and flashtool for the ftf file. wow, what a difference in graphics, this is cool.
I appreciate all the time you've spent on me. Congrats on the 200th, I'm helping you stack up some thanks' too
One last thing, what's the benifit of an unlocked bl? And would it benifit me to unbrand since I have a custom Rom?

For unlocked bootloader there is only one main benefit. You can flash any custom kernel directly. On locked bootloader you can also use custom kernel, but it uses "bypass" method - once stock kernel is loaded, special init script gives the control to custom kernel and then custom kernel is loaded. This is 100% safe for noobs and also devs (I was doing some kernelt tweaks, thats why I am on locked - if I do unloadable kernel and flash it on unlocked device... It will be bricked ). But it takes about 2x time to load the system on reboot, because you need to load two kernels instead just one. If you unlock your bootloader, you can overwrite stock kernel with custom one. And when device it powered on, custom kernel is loaded directly and loads faster then by "bypass" method. Another "benefit" is that all of CyanogenMod ROMs requires unlocked bootloader
Unlocked bootloader doesnt affect your "brand", it wont remove it. As wrote before, you need some service which offers unlocking codes or I saw saome tutorials on youtube (give a search ).
But think this is a little nonsense if you want to use your phone as PDA. "Branding" affects only gsm network and 3G data, so you cant use these features without SIM.
Thanks for the info on the locked/unlocked bl.
Now for another question. Let's say I install a Rom and kernel combo that aren't compatible, you said it'll brick. Will that be a hard/permanent brick or could I just use the pc companion and repair it.

On locked bl you can everytime use Flashtool or PC Companion to reapir your phone.
On unlocked mostly too. BUT, as told you. Only if you flash loader or kernel badly (bad cable, unexpected power shutdown etc.) you cant repair your phone with any software. Or, to be perfectionist You can unbrick it, using the "JTAG" connector with some "JIG" box. These hardware are hard to buy, its highly specialized devices and costs about 200€ or even more... With these tools you can unbrick any device everytime, even with damaged system ROM, or unloadable kernel. It will simply overwrite the whole NAND adress by adress, byte by byte with standart system image.
You can also use some high-level services which are equipped with this hw and could do it for you. But its also expensive.BTW. thats why I am thinking about to buy JIG box perosnally

[Q] My Atrix Relocked the SIM after factory reset and now don't acept the right PIN

I performed a factory restore in the motorola Atrix i had bought in ebay and that made my cellphone get unblocked to SIM cards that are not from AT&T. I have the PIN code to unlock again but the cellphone does not accept it, i'm getting crazzy about it. Does anyone have idea of what i could do?
I'd try (re)flashing a radio or a different version.
Although I'm not saying you should do it.

It's not officially unlocked. Talk to an AT&T representative online & tell him that you're locked. He'll ask your IMEI & give you the unlock code. (for free). Then your set will be re unlocked again.

The phone will also prevent SIM unlocks after too many unsuccessful attempts. You may have went over your limit. Try getting a new code from AT&T. Maybe the code you have is a one-time use only code?

Same thing with my Razr D1 (XT918), I had bought unlocked from a big store here in Brazil. I performed a hard reset (factory reset), and after that, the sim slot 2 does not recognize any SIM card. I remade the reset procedure but it is the same message: "SIM locked ME. Slot SIM you are about to use is locked. Do you want to unlock? Enter (8-16 digits) to unlock."
Apparently, after the reset, the cellphone set a lock in the slot, which can be checked manually by the way:
Settings> Security> Set up SIM card lock
PS: The other slot (1) usually works with any SIM card.
If a had the slot unlock code, I think I could solve the problem, but in some brazilian foruns, I found that its a problem with these cellphone models (D1 and D3). After the factory reset the slot is locked. Motorola replied in costumer service that is working in a solution, but a need my second slot...
Somebody can help?

Is there something wrong with my phone?

I just bought my vs987 less than a week ago, and when I install my T-Mobile sim card, I'm able to place calls but I'm unable to use the cellular data. I thought these were supposed to be unlocked? My data works fine when I use the Verizon sim card.
Also, when I first started it up I noticed that my "Software status" said "modified." Does that mean that this phone was previously owned/tampered with? I updated to 7.0 Nougat via Uppercut and LGUP, and now it says "Official." So, I'm a bit alarmed by what was there previously...
Can someone address both of these concerns?
Also, in "About Phone" in the settings menu there is no "Update Center" option. I looked in this video and it appears there.
https://youtu.be/gXeKZ6Dk4Fg
Is that normal, too?
I would appreciate the feedback because I'm a bit anxious due to the fact that Best Buy apparently charges $35 for returns or exchanges on phones. -_-
Do you know if the bootloader is unlocked? Because on some phones when the bootloader is unlocked if causes some problems especially on stock firmwares!

How can I go about verifying whether it's unlocked or not? I swear if something is wrong they better not charge me $35. I will dispute them via my CC company if they do.
Well a simple way is when it boots up it says “bootloader unlocked and visit this link” or something in that nature and a nother way of checking is going into settings - about phone - software info - click build number 8 times - back to settings - developer options... And if enable OEM Unlock is checked... Your bootloader is unlocked

I checked and there isn't an option for OEM Unlock in the dev options.
Edit: I think this is because the vs987 isn't rootable.
Hmm well I honestly don't know what could be causing this problem I would suggest finding another official KDZ (don't downgrade) from here http://downloads.codefi.re/autoprime/LG/LG_G5/VS987/VS98711A and if possible factory reset before and after

Question Any way around "Locked device"

This phone was given to me by a friend, he says he got drunk, changed his lock code and doesn't remember. After a factory reset it just stays on a screen asking for a Tracfone SIM and he kept his SIM & moved halfway across the country.
I just wanna know if there is any means around this?
I called Tracfone, gave them the IMEI & they told me the phone will be eligible for unlock in about a month, I don't wanna wait as I can't root my S22 Ultra and I just wanna get back in the rooting scene, LOL
I know, call me impatient....
I apologize, I didn't notice a post w/ same issue but on a Cricket phone whereas mine is Tracfone but same situation.

What's the Model and build number? Is the bootloader locked or unlocked? Without knowing much detail I'd recommend finding the firmware that matches your phone and fastboot flash that or at least TWRP recovery if you can find one that works with yours and then you'd have more flexibility. This is all if your bootloader has been unlocked already though and if it hasn't I'd start looking through some threads on how to do that if you don't already know how to. If it's possible with your variant too I know carrier devices are pretty strict on unlocking the bootloader but Idk about tracphone variants.
It's not unlocked.
It's the Tracfone Moto G Power
Look up a thread here on xda about unlocking the bootloader for Motorola devices and come back here if you can unlock it. You'll have to do that before you can even flash anything such as partitions like a custom recovery.
