[Completed] LGK7 Tmobile FRP/ flash or root - XDA Assist

Hello! I apologize in advance if this is the wrong thread to be asking this. I recently bought a K7 off of craigslist. When trying to factory reset it I hit the FRP and am now stuck.
Here is what I tried so far:
1. Bypass by going to settings and adding a new user. We managed to get to settings (I could not get the "dual pane" or overview to work to run the apk) yet we managed to get to settings once. Once there I could not find any "users" button to add one too.
2. Flashing the phone. Now I'm not 100% certain I know what that means. Basically overwriting everything stored in the flash memory with new data? We attempted this with the LG flash tool. I could not find the correct kdz file for this phone. We tried using one for an LGG4 (against googles advice) Yet only got an error message with that.
3. Rooting the phone: Not confident this would even bypass the FRP but figured it might help us??? Downloaded kingroot for pc. Have not tried downloading it straight on the phone although we can't get to file manager right now so... The app, even though I don't speak chinesse, I believe is telling us to turn on USB debugging. We can not seem to get back into settings again.
The info for the phone is
Model: LG-K330
IMEI: xxxxxxxx
Any help or maybe even a "Your out of league stop trying" would be wonderful!

[Q] Unbrick Phone (Unfortunately, Settings has Stopped)

Is there any chance I can unbrick my LG Realm aka LS620. I rooted the phone with Kingroot and then deleted some Bloatware. Doing that I must have done
something to some vital system apps. Now my situation is as follows:
-cannot access any system settings(error message: Unfortunately, Settings has stopped)
-other apps like Contacts, Messaging, Gallery, E-mail give me the error message: Unfortunately, 'Appname' has stopped.
-phone still boots up
-since I cannot access Settings I can NOT enable "USB Debugging" or "Unknown Sources"
-since I cannot enable those, I cannot connect to a PC to use adb to sideload apks or install non Google Play Store apks like Towelroot
-I still can put the phone in "Download Mode"
-I performed a factory reset which did not fix the problem, actually it made it worse since the phone is not rooted anymore, as verified with Root Check
I tried to flash the phone using kdz and tot/dll files for the LG L70 which is a very similar phone but that gives me only errors. I cannot find the
firmware for the LS620 anywhere as apparently a lot of other people can't. I spent now more than 2 unsuccessful weeks on the internet trying to find a fix
for my problem. My thinking is that if I somehow could install Towelroot by maybe tricking the phone to thinks it is a genuine goole play store apk I could
then trie to root the phone again and re-install the Settings system apk.
At this point I am out of my wits, but I refuse to believe there is no solution. There are a lot of smart people out there and on this forum, the answer
must lurk somewhere. The simplest of course would be to find the firmware for the LS620. So, if you can help please respond and let me know. My apologies
for this rather lengthy post.
Thanks,
Joe
hey
it sounds like you are stuck but let me get some info together and I will try and help you out

Yeah,
I knew this site. But before you can download anything you must register which I tried but was unsuccessful to do. Not all the Chinese text on the site is translated with Bing translator and becomes is kind of confusing. I could not find any reference to a firmware file in the link you posted. But thanks anyway for responding. --Joe

[Completed] How do I unbrick my phone?

First of all, I'd like to say that I know very little about how Android, electronics or mobile phones work in general, so everything I've done has been from internet tutorials. Please don't use any jargon as I probably won't know what you mean. ELI5.
A few days ago, I tried to root my phone and it didn't work. As a result the phone went into a boot loop and I didn't know how to fix it. The long and short of it was that I ended up flashing the stock firmware onto my phone and basically doing a complete factory reset. After some time trying this I managed to get the phone to start up and I was able to access the interface and all that. Unfortunately, my WiFi wasn't working (the button would simply turn off whenever I turned it on) so I had no way to download the most recent updates or apps or anything like that. After following several tutorials on how to fix this, such as flashing the modems and bootloader, I still wasn't having any luck. So I tried something that proved to cause even more problems - I tried to install a new kernel. Now my phone won't even boot past the logo. I probably didn't install the right one, but what can I say, it's not very clear which one I need.
Now I'd like to point out that as a layman who just wants his phone to work again, half of the time I don't understand what I'm doing or whether or not I'm doing it right. In other words, I realise that I've probably messed up my phone, but what can I do? I can't take it to a technician because I don't have the money for that, I can't buy a new phone for the same reason and I can't phone up and ask for a replacement because the warranty expired ages ago and I don't have the original documents here.
I've installed the Team Win Recovery Project on my phone and I have Odin installed on my PC as well.
TLDR; yes, I know I'm an idiot and I don't appreciate you telling me. I'd like to reset my phone to how it was before - the normal firmware, the normal kernel and all that, but I'd still like to have root access and keep the TWRP recovery mode too.

You'll probably need more information, so if you do just let me know and, if possible, where I can find it.
I have some good news. I managed to flash the firmware again and now I can access the phone again. However, the WiFi problem persists. I've tried looking on the internet for a solution, but I can't find one. I've tried flashing the modem and all that stuff, but it still doesn't work.
Oh, and by the way, I no longer have TWRP and I don't think I have root access anymore either (I had to do a data partition wipe as well).
I'd really appreciate a reply from someone. I've tried everything, but to no avail.

Hi engloa,
It's OK, I've fixed the problem now; I installed a different ROM and now it works fine. Thanks anyway though.

lg optimus zone 3 lgvs425pp stock firmware dump

hopefully this will help out some people and the developers to make,fix,restore a not so popular phone. I did a total firmware dump and have uploaded to my 4shared folder. If anyone is interested or can tell me how to upload it here for developing i will be more than happy to share with those in need. I also have a spare phone that i would be willing to test anything made from the firmware dump i created.
PLEASE link?
Some time after rooting my Optimus Zone 3 VS425PP, I got locked into a boot loop. There are no custom ROM's, neither recovery nor OS. It's not bricked. Yet, anyway. The loading screen functions, then a little window that says "OPTIMIZING APPS 1 OF 5, PLEASE DO NOT REMOVE THE BATTERY..." appears. I've seen this before, but now, upon reaching "APP 5 OF 5," it reboots and repeats. I've tried several factory resets via the LG RECOVERY (MODIFIED,) as well as safe mode to no avail. Anyone? Anything? Help? The only recourse I can think of would be to re-flash the stock ROM, which I cannot find. Anywhere. Thanks, guys.
i tried contacting judthro for the same file; no luck

Unfortunately, I don't think this file is actually out there. I have REALLY been looking, even contacted the LG Development team. The LG Support Tool, etc. are not going to help you yet as they do not have the firmware on their servers yet. That's why the LG Support Tool will freeze when trying to do an Update Recovery on this phone. -- And I've tried them all: LG Mobile Support Tool, LG PC Suite, Verizon VS425PP Update Tool (from the mounted drive on the phone), LG Flash Tool 2014 to force different KDZ files. All provide nothing. All dead ends. The Optimus won't grab a COM unless it is the right signed firmware for the phone. You'll just sit there in Download Mode or in Debug mode forever with no result. We have to wait for the first update from LG from version VS425PP1 to whatever comes next so they have something to stick on their server. But...if you find something before then, please let me know! The update will eventually be released to the public. It'll probably just take a year or so.
Good thing is Wal-Mart sells these for under $12 (yes, that's right). I picked up seven of these quad-core bad boys at that deal. Just bugs the hell out of me I can't fix the one I over rooted.
this *might* be promising...

well i'll be. this may be a promising link:
google "4share lgvs425pp" and scroll down to the 4shared link. There is a 999MB RAR file claiming to be the VS425PP ROM dump. I'm downloading it now...checking it out.
It works???!!! i have to root this cellphone because i need use with other company...

hopefully the op will chime in for insight. The 999MB isn't much good. It appears to be a RAR dump of all the partitions, perhaps made from a lglaf.py script while in download. Nevertheless, i havent found any way yet to push the firmware dump onto the phone.
I've had no luck, either.

Meanwhile, as my LG cycles endlessly through my really cool "Jolly Roger" boot animation, I stumbled across a Kyocera Hydro Wave at Walmart for $20. I snapped it up to replace the LG Optimus Zone 3. I had big plans to root it, too., but I should've researched it first. The specs are great... but one check on Cyanogen's website probably would've saved me some trouble. Not one Kyocera device is listed there. XDA thread also throws red flags-no one can get root to stick. Well, I at least learned a lesson. Next time, I plan to purposefully buy a phone that can be rooted, has been rooted, has instructions online to do so, AND has at least one custom ROM available! No wonder this thing was $20! Keep us all posted if you stumble across a bootloop fix of some kind, and I'll do the same.
here is stock recovery for this device https://www.dropbox.com/home/Apps/Flashify/VS425PP/recovery
matt4787!
Either I am unable to open that link from an Android device OR the link given is to an unshared folder? It just asks me to log in and then says 'that folder does not exist in your DropBox...' PLEASE check out the SHARE link from within your DropBox and maybe share a new folder (and drop the stock ROM in there, along with what you might've used to flash it maybe?) We'd be very grateful!

To all who have a bricked,phone this phone has an update. Download the LG software assistant and put assistant in repair mode then boot phone normally and wait a bit. Run the repair assistant and let it run. Hopefully if everything runs well as it did me. Mine is restored and running.
Just ordered one. Is there root for this phone? Unlocked bootloader or forgetaboutit?
I rooted this phone and then tried to de-bloat, but I must have deleted too much. Now when I boot all I get is "Security Error - Authentication Fail #9"
I can get to Download mode, but none of the recovery programs recognize the phone. I installed the drivers, but still nothing. Is there anything I can do?

was your phone in a "security error" loop? for some reason the software assistant won't recognize my phone. it'll identify a plugged in phone when I connect it in download mode, but the device model never shows up

i forgot to mention that you have to be in download mode to make the assistant recognize the phone. plus make sure the drivers for the phone are installed on your pc

LG Stylo 2(K540)- At this point I'm begging for help!

I'm new to the XDA Forums and even forums in general so if I speak out of place or anything like that I apologize ahead of time. So anyway, where do I start? I'll try to give you the short version. So I bought an LG Stylo 2(model: LG K540) through Cricket the day they came out. It was $170 phone. On the second day of using my new phone I got the bright idea that I'd try and root it BY MYSELF. I knew better but for some reason I had this false burst of confidence & thought I had everything under control. Well, thanks to Kingroot that burst of confidence didn't last long and there I was with a 2 day old phone BRICKED. Reason I never posted on the forums is because I've got a buddy who , in my eyes, knows everything there is to know about Android and thats who I'd normally go to when I wanted to root a phone so he's who I immediately turned to but even he couldn't figure it out. He couldn't help me unless we had the stock firmware or someone with the exact same phone and according to him we could some how use a backup of that phone to fix mine. Cricket just wanted to sell me another phone even though I was standing there with a 2 day old phone and LG just wants me to send the phone in to them, which I have no desire to do. I've searched all over the internet trying to locate the firmware because even I can fix the phone if I had that but nothing. Had hoped by now LG would have released the firmware but at this point who knows when that'll happen. I'd even pay for it at this point. Anyway, just thought I'd give the forum a shot on the off chance someone might be able to help me or point me in the right direction. Oh and if you were wondering what the phone does now, when I turn it on the LG logo appears like it should but then right as it appears you see a message in red lettering that says: BOOT VERIFICATION FAIL!!- CAUSE: MISMATCH_SIG_LEN And it just loops this over & over until you pull the battery out. Please someone help me!

Source code to rom¿?
I ran into basically the same situation as you. I'm currently downloading Android open source project on to a fresh install Ubuntu 16.04. I am currently in the middle of running sync.
I'm curious if there is anybody out there who would be willing to give a few pointers, on compiling the ROM from LG open source code. They told me I had to use it in the readme.txt.
Im a noob with fair knowledge of modding and stylo not stylo 2. There's no way to say for sure if this will work but on lg mm on h631 u need to unlock dev option in settings 1st. Make sure to check off oem unlock and usb debugging. Connect to pc and you will get a popup or 2, one will ask to allow pc to connect to phone, the second is to allow usb debugging. After you allow both, open cmd in your adb fastboot folder. Type " adb reboot bootloader." should reboot the phone to bootloader/fastboot mode. Then you type " fastboot oem unlock." you will see sending.. Once sending is done type " fastboot reboot." when the phone restart you should see bootloader unlocked on splash screen. Then i rooted with kingroot. Then use rashr to flash twrp. Then used twrp to flash supersu to get rid of kingroot.. My h631 now in business and i just started working on a port for lg ux 5.0. This is the guild i use for a better idea http://forum.xda-developers.com/lg-g-stylo/how-to/guide-lg-g-stylo-how-to-root-t-mobile-6-t3333916. You might need lgflashtool and kdz to unbrick..
NO NEED to beg.
I don't know very much but I know $$$ talks and since no one save the few who suggested contacting lg wants to help, Ill try. At the moment I am efforting a solution via the Chinese. I expect to have a working copy in the next 48hrs. when I do, we can arrange for you to get access to the mega.nz cloud and get urs.
say a prayer......

BIN File
Hello, I have a Stylo 2 K540 from cricket, it is having issues with the Wi-Fi, it will not connect to either Wi-Fi or bluetooth, MAC address was set at 02:00:00:00:00 or something like that, I opened the phone and it has humidity sensor active, cleaned the affected area but it seems like it was useless, eventhough I was pretty sure that was not the main problem. I looked for some troubleshooting options and found non of use, firmware is sold for $30 online so it is not an option since I am not certain loading firmware will be of any help. I tried repairing MAC address via Octoplus using other addresses but was useless as well.
I have little to no experience with software on phones, but I like to read and learn. I decided to connect the phone to the computer and "Read full flash" on Octopus, I have created the Bin file, I have a perfectly working phone as well, I was wondering if there is any way to get the KDZ file from the Bin file doing some sort of conversion, or if I could do some sort of fix or workaround with this bin file, I can share it if anybody needs it or if it can be of any use to get the firmware

Galaxy S8 Issue (Regarding bootloop)

I decided to root my Galaxy S8,and im pretty uneducated on how to do those sorts of things, but there is what looked to be an very easy tutorial (snapdragon).
while following those instructions, i missed the requirement of needing adb, and so odin(prince) failed. well, i disconnected my phone. took it out of download mode.
now its forever stuck in an infinite installing system update loop.
i checked for solutions online. go to commands, a factory reset. ect ect
except i get a:
#fail to open recovery_cause(missing file)
which leads me to believe i messed up my software, no biggie, i can just fix it though oden... right?
wrong. opening oden ive come to realize i can no longer get my phone into download mode, and neither does oden recognize my phone as a well... a phone.
so im at a loss of what exactly to do.
do i go through my provider, hoping they fix the issue?
do i wait for a solution here, one i might not have the skills to accomplish?
or do i pay out the pocket to get someone to fix this thing. i really dont know

now its forever stuck in an infinite installing system update loop.
i checked for solutions online. go to commands, a factory reset. ect ect
except i get a:
