LG C800
Device will not enter fastboot.
Can't get into recovery mode.
Each time it boots it hard resets. There is an unofficial CWM Recovery Rom on this forum from chui101 which is for this exact phone, but I have as of yet not had any luck in getting the phone to take it.
So far i've tried Flash_image recovery.img (renamed chui's CWM recovery file to recovery.img)
Doesn't seem to matter what I do the phone starts(LG on screen), resets (the LG goes away for a sec then comes back), does a hard reset (a white box with an arrow pointing out of it an to a little android), again resets the phone one last time for a "normal" boot.
I've tried a few different things to try and flash anything overtop of the stock recovery but nothing works. It seems like very early in the bootstrap is a command to do a hard reset and anything that gets put in AFTER that command is ignored. (And the phone hard resets and anything else it was supposed to do is gone.)
Device is rooted with SuperSU.
Phone is fully functional except that it hard resets every boot, and if its plugged in when off it doesn't go to a charging screen, it starts the phone 100% up.
Adb devices CAN see the phone.
I CAN get into Download (sometimes called Emergency) mode.
"reboot recovery" doesn't do anything but reboot the phone as described above.
I can't afford a new phone guys, so I'm over a barrel at this point.
i'll pay whoever provides meaningful help in getting this thing fixed.
You should start fresh. So, flash the stock rom FTF of your phone, then the phone should boot up normally. Then you could either root it and install a CUSTOM recovery, or flash a pre-rooted custom kernel that already contains a recovery. From there, just flash the custom rom you want
Just press thanks if I helped, no need for money
stock rom FTF?
From the factory?
I'd love to do that. But am bewildered as to how when every guide I've found says use fastboot -- which doesn't work on my device. And every guide without fastboot thus far has not worked. I've been reading 10 hrs a day for the last 3 days looking for a solution to this.
If there was a way to completely wipe the entire phone and then install stock rom I'd be glad to do it.... I have found no such guide... only those to replace recovery. (not a 100% clearing as if it came right off the line with no software yet installed)
Additional information:
mv /system/recovery-from-boot.p /system/recovery-from-boot.p-bak
Spits out a "No such file or directory" error
I don't know about you, but for Xperia Devices there is a PC software called Flashtool to flash stock roms and custom kernels and stuff from the PC. There should also be a software like that for your device. You just download the stock FTF for your phone (just type in google "download stock FTF for LG C800") and flash it in Flashmode that should be working
One more thing, this issue is not called bricked
press thanks if i helped
There is an LG tool but it says current software is up to date.
Other option is run recovery, which just reboots the phone as is.
No, this software I am talking about is not made by LG or Sony in my case. It should be a general tool for all LG devices. it should root, flash, install busybox, etc......

LG MOBILE SUPPORT TOOL ?
Thats the one that so far doesn't work.
the one named:
KDZ_FW_UPD_EN ?
He doesn't appear to support GSM phones. Plus I hit "Read info from phone" button... it gets almost everything -- correctly -- then crashes.
IT wants kdz files... looking for them now... chui has a dl link for the stock recovery but even though its a few mb it looks like only a zipped folder hierarchy with no files.
Slightly mis-read. still not finding any "generic" flashing software
trying octopus now....
crashed....
run as admin..... ah... you need their hardware which is hundreds of dollars...
Flash image gui, phone is not supported.
ok, a couple cyanogen dev's have both told me i'm screwed. Imma try for the rest of today and then just never turn it off again.
ok, paying lg to fix it... anybody guess what that will cost?
Try flashing CyanogenMod on your phone as no stock firmware is avaiable currently for your phone cyanogenmod shall fix the problem and you should boot normally (first flash CWM)

Flashing cyanogenmod (requires usb debugging on)
First to put the cyanogenmod rom in the sdcard use adb push - http://forum.xda-developers.com/showthread.php?t=1667929

Probably will fix the problem....
hi techmasta,
I'd love to flash cyanogenmod, but the phone never enters fastboot to flash anything. The first link you posted says to use fastboot. I can't do that. The phone doesn't goto fastboot, it runs its recovery first.
EDIT: if there is a way to force it while the phone is in download mode that could probably work.
secondly, I've spend more than 40 hours on this issue, mostly reading forums but still a great deal on google.
I'm pretty unhappy with google as neither of those droidnoob forums ever come up. And believe me, there isn't much out there referring to the lg c800 so they should have!

Ok the web just glitched on me so this is the second time of me writing this novel and patience has grown very thin. First i would never be asking for this help if i didnt already do my 5 days of research and exhaust all solutions i can see. And since this is my second time writing this im sorry but im going to give the short version. I did the fatal mistake of lg style reset while i was rooted i know its a rookie mistake i thought i was completely unrooted and didnt double check it before i continued. i cant boot into recovery at all or if i can its just a black screen. when i boot normally it goes to the lg logo then to a black screen. i can access emergency mode however i cant get my pc ( running xp sp3 ) to recognize the device. I can get it to be recognized when i boot it normally to the black screen and even gain acces to root through adb, When in emergency i get nothing though and i have attempted recovery and flashing through adb, kdz, romtools, lgmdp and a few more randoms i could find in the forums ( i have done a lot of research ) when i do establish root though i cant seem to push or pull files, flash, mount or anything besides adb shell, the rest is filled with error: 0's and sbin/sh "whatever" not found, etc. since i can establish root it leads me to believe this can be fixed. THANK YOU in advance for any help you can throw my way and I'm sorry if this post is vague, poorly written ( like i said second time going through this ) or gets under your skin i know better that you veterans hate reading these posts and im only asking for help because now i am at my wits end. Thank you again
hey it would be nice if you could tell something about lg style reset and that rooted thing..... I don't have any info. about bricking the device like this.... ;-)
just wanted to know as a word of caution....

I m not aware if lg p500/optimus one clockwork mod recovery will work on optimus v.
If recoveries of both phones are same you can follow http://forum.xda-developers.com/showthread.php?t=1318750 to install custom recovery of lg p500/optimus one from emergency mode.

Rooting is the process of essentially gaining Administrator rights to your phone ( So you can access files and gain privilages you wouldn't normally have ) Think of it like a computer and your signed in as a guest when you root your signed in as the Admin, Hope that helps. LG style reset is the factory reset of the phone from the recovery menu to restore the phone to its original state, Which is a huge no no while rooted or a custom recovery is installed.

I attempted that and its a no go. The main problem being i can not get my phone to be recognized by the computer while it is emergency mode and i can not even select an image or anything. I booted it normally ( into the black screen i get after LG logo ) And i dont recieve a pop up with image and i recieve a error everytime i attempt to backup my nv its doesnt seem to be found, Nothing, but the device does get recognized at least.

Are you able to connect to phone from lgmdp when booted normally ( into the black screen you get after LG logo ).
If yes then
dont back up nv
no need the pop up window, press on "select image" in lgmdp and browse to recovery extracted folder for "image folder"
then press "start or download"
fix-black-screen-custom-recovery-custom-roms
I'd've posted it here on xda, too, but it's quite enough manainance dealing with it in one forum already.
the problem is that lg started shipping the optimus v with cheaper hitachi screens instead of the novatek screen it was released with. so the older custom recoveries and roms use a kernel that isn't configured to use the hitachi screen and you only get to see the backlight with no display.

the p500 kernel is incompatible (different chipset.) so the recovery won't work even it the mtd map is the same.
bummer, as that's be a nice easy fix.
Mak Thank you for the progress i have made so far i did manage to get the phone connected through lgmpd as i have before however this was the first time when connected it went straight to emergency ready ( in the lgmpd screen ) I am going ahead to assume that is good i was never able to get it that far. The problem i face now when i press the "select image" button nothing happens, as long as the button is pushed down the word ready in the bottom left disappears and when released the word reappears, However i dont recieve the option to browse any menu for the image. Is there a specific folder i should have extracted to? I'll continue my research too if i find out the problem i wil post it immediately, Thank you again for your help i'm not there yet but definately making progress.
Squid, I knew about that topic too i remember reading it during my research, It must of slipped my mind before i even though about posting this. I'm Sorry ill be more careful about making these posts in the future
Also Squid since the chipsets are different i assume thats a no go, Would it still hurt to try? i'm running on hopes and dreams at the moment. Also when booted normally to my black screen i can obtain root access via adb leading me to believe if i can do that a fix is present somewhere

yes, a no-go. when I flashed a p500 kernel to my v for experimental purposes, it wouldn't boot right for a day even after putting a working kernel back on it. it had to sit with the battery pulled for a few minutes between boots or it would just freeze on the lg logo.
if you follow the adb instructions to install a compatible recovery (currently, BobZhome IHO recovery is advised) in the thread I linked to, you should be fine.

yes, as long as pressing the "select image" button ready in the bottom left disappears. But when you release button you should get a window poped up to select image folder.
Try again to connect in emergency mode and see.

I did follow those instructions previously ( 2 days ago i believe ) When i attempted that i was not able to push the needed files to my sd card unfortunately and i did try multiple times using Xionia recovery. I understand user error so I'll try again with a fresh mind just to be certain and get back to all of you.

I know what rooting is....infact I myself is on CM 6.5.8
what I didn't knew was that factory reset with custom recovery can brick our device..
but I feel this is not true as many people had done factory reset when they had problems after restoring nandroid backup....
I know a corrupted /system partition will cause the 'system/bin/sh not found' with adb if you're booting into the rom, I hadn't seen that booting into recovery.
if you have an older optimus v (2.2.1 froyo original, pv5 baseband) you can
Code:
adb reboot bootloader
to get to the bootloader and use fastboot to flash the recovery or even the whole system.
2.2.2 optimus v with pv7 firmware has the bootloader locked, so trying to reboot into the bootloader just tries to boot to the normal ROM.
My apologies Fundoozzz i was not insulting your intelligence just covering all basis, And from what i understand when you choose lg style reset from recovery it is the same as perform the factory reset from the settings menu which i guess your not suppose to. I by no means am not an expert on any of this obviously, I'm just simply relaying the information i have read on these and android forums as well as my personal experience.
Squid, I purchased this in the beginning of sept. and as i understand the revamped the Optimus in August?? So yes im running the later version and to double back on the posts I tried to push files again and attempted fastboot before still with the sbin/sh not found error....I am still hopeful that this is not a paper wieght however it very well could be thank you both again
have you tried booting into the blacked recovery before using adb?
(hold home+vol down while pressing power until lg logo goes black)
it sounds like your rom was corrupted (so adb is fairly useless there,) and recovery might be working but you just can't see it if you do have a newer OV.
to force reboot to recovery without the button-smashing,
adb reboot recovery
while you're booted normally.
then try adb again.
please cut/paste the errors you're getting with the commands you're using, here in this thread..
Well all be cheese and crackers, Thank you Squid it did the trick to actually push the image to my sd card here are the commands that I used....

Now before i move further just to humor me all i need to do is push the flash_image and reboot to recovery and i should be good from there to flash a new rom. I ask only so i dont mess this up any worse than i have
if you're in the recovery, flash_image is already in the PATH.
Code:
adb shell
flash_image recovery /sdcard/vm670nh_recovery.img
exit
adb reboot recovery
then you should be ready to see your recovery.
format cache, data, and system.
install the rom.zip as usual.
THANK YOU VERY MUCH, How I wasn't able to obtain this I'm not too sure lack of knowledge or user errors possibly regardless I am now in CWM recovery and will format and flash my new rom. Any suggestions by the way? I was considering CM7 but i heard mixed reviews about it on the Optimus v. Oh well I'll do some research Thank you again Squid if i can repay this debt let me know, Lets face the facts in reality you just saved me over a hundred dollars and countless more headaches. Thank you again to everyone, much appreciated!

Well easy come and easy go back to a new LG screen. So after managing to get the recovery working i went to flash CM7 on the Optimus using information here http://androidforums.com/optimus-v-all-things-root/366620-cm7-installation-my-optimus-v.html Anyway I am now experiencing this problem, I get stuck back at the lg screen again. I did wipe the cache data system 3 times to be safe before flashing the rom and i only have access to emergency mode and this screen ( regular boot and recovery mode come up and end the exact same way ). I'll explain what i see step by step...
1. The black and silver LG Logo
2. A green Android guy next to a box with arrow coming out and these words come up on the screen. " with out the numbers of course "
(1) Android Recovery
(2) Do Not Pull Battery
(3) Formatting Data:...
(4) Formatting cache:...
(5) Factory Reset...
(6) Rebooting...
3. Then reboots back to the black and silver LG Logo screen.
4. Finally stops and freeze's up on the screen with a pinkish/reddish LG symbol with LG next to it and www.lgmobile.com written underneath it.
Question being is this some sort of recovery boot loop? And if it is what can be done about it? Furthermore many if not all files on the phone so far seem to be " read only " .... well i guess I'm ready for round two!
I want to perma-unlock the sim so i wont have to use sprint because they suck eggs. But using a program called autorec, i am stuck in fastboot. I have tried the download thing where you power off and plug in the usb to get download mode, but as soon as it powers on it goes directly to fastboot or download mode pops up, then is sent directly to---YOU guessed it! FASTBOOOOOOOOT
So i need to go back to square one, and start from the very stock LG G2 Ls980, help will be appreciated. I will post links of guides i tried but led me to this problem. Also, anyone who would like to post a good guide, no problem, to unlocking the phone to be used on another rom such as AT&T or Tmobile, that would be fantastic. I want to get this phone up and working to replace an old phone, but sprint is a egg sucker.

I really ****ed it up now due to every flash to stock from fastboot menu on this site. It is black screen cant even access anything, no stock rom ANYWHERE ON THE INTERNET WTF and i am beyond irritated with how many inaccurate threads on this site. The phone altogether is really pissing me off. **** sprint for making their phones just as ****ty as every service they have.

I work on that phone all the time and never remember seeing any threads for restoring via fastboot...? The preferred way is via kdz and the LG FlashTool. So once you power off and leave it off for like 30 secs then hold Volume Up and plug in the phone does not get you to Download Mode? Have not seen that one before...
As far as unlocking, especially if you aren't going to use Sprint again, I prefer to use one of the roms that is based off GSM with the Sprint kernel so it'll boot. I like the Energy rom for 4.2.2. Works and looks great. Have installed it for quite a few customers and have never had a complaint (well, one wasn't a fan of the dark theme, but can't please em all...) or anyone bring it back to me. There is a newer one that is like a stock rom but 4.4.2. Haven't tried that one since I like to stick with what I know works and haven't had enough chance to test the new one.
The steps I take are:
Use LG FlashTool to go back to ZV7 update
Root with ioroot (at leave version 22 and 25 works too)
Use Flashify to install the loki-ed TWRP 2.6.3.3
Reboot to recovery
Install Energy rom and ZV8 radio (must flash radio or it will not boot)
...
Profit!
PS: If you need NFC, there's a separate zip to flash.
I have everything for this operation uploaded to my Mega account and have performed it remotely. If you're just completely stuck and you can still get into Download mode, let me know and I can help with whatever else you need.
Hey guys, please forgive me for any bad etiquette or lack of information (any information I can provide is available upon request if I leave anything out). I am new to forums in general and especially to XDA, which seems like a good place to get help.
I recently purchased a Sony Xperia Z2 Tablet from Craigslist under the assumption it was a fully unlocked tablet not associated to a carrier. Turns out it was a Verizon Z2 tablet. I dislike Verizon with a firey passion and without getting into too many details, I'm fairly certain they won't help me because a) this tablet wasn't purchased through them as a customer and b) Verizon and I have bad history (unauthorized account modification, shady charges, etc.)
So I thought I'd do my best to make the tablet mine since the asshole who sold it to me has ceased all contact and I don't know how to get a hold of him anymore. No receipt and a data-less tablet.
Anyway, I successfully rooted the tablet and began installing apps that I installed for my G4 when I rooted it (SuperSU, Adaway, Greenify, etc.)
Things were going well but I realised I wanted anything that had to do with Verizon removed from the tablet so I was going to flash Cyanogenmod onto it with a guide I found online. Now rooting and installing custom recoveries was familiar territory and I did these flawlessly. It had TWRP and I made a backup of the system -no Nandroid, sadly-and I began the flashing process. The process said it completed without issue and I went to reboot my device. Enter my current situation:
The device, when I attempted to turn it on, all it did was vibrate constantly until I let go of the power button. Attempting to enter recovery mode (green LED, power + vol down) it showed me, instead of TWRP, a very basic recovery mode with basic options. "Continue booting up", "enter safe mode", "system recovery", and "power down". I tried entering safe mode and it just shut back down, I tried doing a system recovery and it shut down. The only time I ever see the "SONY" logo is if I'm entering this mode. I can enter what I assume is "fastboot mode" (power + vol up and plugging the device into a PC). Nothing on the screen but the LED is blue. I am trying to find guides to restore it if I can and it all looks promising but the only things I know how to really do are root and install custom recovery. I know there are PC tools I can use to send commands to it while it's in fastboot, or send commands in general I just don't know where to begin.
Does anyone know how to fix this? I know it was from Verizon, which sucks, and I know the problem most likely occurred with the attempted flashing of Cyanogenmod. I think I read somewhere I might have done something regarding mismatching kernal numbers. I couldn't find a way to unlock the bootloader so I assume that had something to do with it too.
If someone could give me a guide to restore it to at least its stock ROM where I can begin rooting and installing a custom recovery again, that would be great. Even better would be just flashing a ROM on there that doesn't need Verizon or being able to take it to a stage where it's unlocked and the only evidence it was ever with a carrier is the Verizon logo on the back. I'd really hate to think I wasted money on this and now I'm at a dead end because of a mistake I made. This was supposed to be a gift for my mom on her birthday which is coming up soon. So if anyone knows anything, or has a guide where we can at least get the thing bootable again and I'll just try and deal with a rooted locked device, that would be great.
Thanks for considerations,
Marmalade_Shaws
I have spent time on that screen too.
2 things
1. .. If you installed dual recovery, there is an up, down sequence to select the recovery.
2. Find a downgrade guide, use flashtool to flash. Ft back to stock.
Also you need to know what hardware you are running..511, 561.. And use the proper version.
There are some options with the flashtool and prf maker that can remove branding and vendor stuff. I have not tried those options.

Sorry if this is late... But where can I find the stock? I've searched everywhere and I would need to do it from a flash tool on my PC? I could use all the help I can get.
I just had a very similar experience to the OP, seemingly identical in every way, and am curious if anyone has a solution.
ADB won't function at all, and the bootloader has blocked any sort of flashing via fastboot. Can't boot into TWRP, it goes into a very minimal "recovery," which I imagine is the stock tool, and the Factory Restore option there does absolutely nothing. Flashtool would work great if ADB / Flashmode was at all functional (device blinks and vibrates in a fashion typical of something bricked, and no connection is picked up).
Verizon Z2 Tablets are 561s.
This thing dead or is there some way to push back onto it?
As the topic reads, I've been trying most of the day to unlock the bootloader, I went through the process of obtaining my unlock code and my phone status when typing out a code suggested that it allows unlocking of the bootloader - I'm thinking okay cool, hopefully I'll have Cyanogenmod 12.1 on this thing in no time, right? WRONG! The device needs me to download and install fastboot drivers, which I thought should be an easy process but no matter what I do when I look at my phone through the device manager all I see is 'S1Boot Fastboot' - I even attempted using Flashtool (not Emma) and it too says install failed when trying to download the files needed. I just really need some help getting through this part of the problem, I've downloaded the SDK downloaded the USB drivers, updated them with the file from Sony but the end result remains the same. If it makes any difference (which I'm sure it will) I'm on Windows 10.
Thanks for any and all replies .. Edit // I forgot to mention the model is C833 and I recieved the latest OTA update from Sony for Lollipop 5.1.1
Installing the SDK is quite the overkill.
- Install ADB and Fastboot by downloading and running this tiny installer. It'll do the job for you.
- Install Flashtool and be sure that it recognizes your device. The device should be powered on when you open Flashtool the first time.
- Click the "BLU" button and copy/paste the unlock code you received from Sony.
You're done
Be sure to backup important stuff on your phone, in case something goes wrong. Move photos etc. to your SD card or something.

I appreciate the reply, and I managed to get the bootloader unlocked (I think) as both ADB and Fastboot are acknowledging my phone now. Problem I have now is while in Cyanogen Recovery, I hit the first option and may have soft bricked this phone - the cyanogen wiki stated I could make a backup by booting back into Android which is what I tried to do. I'm in the process now of repairing it with the PC companion hopefully and then I'll give it another go, this isn't my main phone though so basically I'm just tinkering/trying to learn the basics of installing custom ROMs. Thanks again for the reply, and if you have any other suggestions for me be sure to leave em here. BTW, I never installed the full Android Studio, just the zip file for the ADB and Fastboot files, I attempted that at first but found out you didn't really need em in the first place.
The CM Recovery is... pretty crappy, so don't use it if you don't have to. If you soft brick it (i.e end up in a bootloop or something), then just flash or hotboot a kernel with recovery, and you're good to go again, so you don't have to re-flash a ROM.
You can either use fastboot to flash a kernel (if you know how to use a terminal), or you can use Flashtool, QuickIMG etc, so:
Soft brick?
- Download a custom kernel with recovery. Doesn't matter which one if you're planning to flash a ROM straight away. You're planning to flash CM12.1, so you can use a random Ultra kernel like this one.
- Let's say we'll use Flashtool to flash it (since you already have it installed). Open it, hit the lightning bolt, click "fastboot", and then "kernel". Browse and choose the kernel you downloaded. Now disconnect from the computer and remember to press VOL up to enter recovery when it vibrates or the LED lights up.
- You're now in recovery again and you can go ahead and flash CM12.1. Remember to WIPE before or after you've flashed CM12.1. You'll end up with a bootloop if you don't do it. If you do, flash that kernel again and you're back on track.

Gonna give all this a shot since the PC companion doesn't seem to be doing anything - I'll post my findings in a few if you're around. Thanks again man, I really appreciate your help.
Edit // Okay, nothing seems to be working now .. Flashtool says that my device has USB Debugging disabled, and whenever I power on the device you see the Sony logo, then a violet led and then the screen stays on and every once in a while it'll show a small battery indicator.

Hmm, plug in the wall charger and charge it for a bit. I highly doubt that it's hardbricked since that's very very hard to achieve on a Sony device. Just kick it into fastboot by holding VOL UP while you plug it into your computer. The blue LED will light up. Then open Flashtool and flash the kernel, or download QuickIMG and flash the kernel (.img) with it. Be sure that it says "connected" before you do anything. Keep also in mind that you have to be in fastboot.

I seem to have a brand new issue now, umm whenever I unplug the device and press VOL UP, I get this distorted screen. It's blue and has what looks to be white wording in the middle, I can't make it out though, this is after I put the kernel you recommended on my device. The kernel is the IMG file, correct?
Just thought I'd give you a bit of an update, I now have Cyanogenmod 12.1 on my Xperia Z Ultra - I flashed the custom recovery that came with the nightly I downloaded and then moved the actual zip to an SD card since like you said Cyanogen Recovery is a bit wonky (I tried sideloading to no avail). I have a couple question though, during the install process I noticed it said something about there 'no such volume' and I was sure I seen two failed prompts too but the ROM is on my phone? Should I look into that at all or is it fine? Most things seem to work .. camera, bluetooth, gonna have to throw my sim in there one of these days and test the cellular radios, but I just wanna say thanks again .. I learned a lot and managed to make something happen even if it's something small like installing a custom rom lol

Just ignore that error. I've seen that myself a couple of times, and I don't know what it means, but it doesn't seem to affect anything.
There are a couple of things to keep in mind. CM12.1 has had some glitchy WiFi in the past, and I believe some people are still experiencing issues, so if you also experience some WiFi issues, it's a CM issue and not a hardware issue. Also, keep in mind that the Ultra GPe (Togari GPe) exists and is also supported by Cyanogen, so be sure to not flash the wrong version since the partitions are different between those two. I believe the recovery system will stop you from flashing it though.
Since Sony devices do not have a default recovery system, we have to bundle it with the kernel, so all custom ROMs around here, including CM, will have a recovery system added, but if you flash a ROM without a recovery system (like a stock ROM that you flash with Flashtool), you'll have to flash a kernel with a recovery yourself.
It's pretty easy to recover from issues and stuff on a Sony device once you know how things work. It's also a good idea to learn how to use flashboot through a terminal since that will potentially save you a lot of time down the road

Everything seems to be working quite well so far, including the wifi but I'll keep what you said in mind. I used the same process to install GApps on it too so now I have the play store and google apps install as well. I have another question though, whenever I plug in a charger to charge the device .. I notice the screen never goes off but stays black and has nothing on display sorta like ambient display, would you know if that's a feature of Cyanogenmod or did I goof somewhere during the install? Thanks in advance for your reply.

Could it be Daydream? Go to Settings -> Display -> and disable Daydream. Now check again. If it's not Daydream causing it, then it might be a bug. Do a reboot in case it's a small glitch of some kind. If it's still on when charging, then I'm not sure what it could be (other than a bug, that is).
Sorry for the late reply, but I figured out the reboot issue .. I had to turn off the 'wake up' feature when you plug in your device. I have a whole new issue though, I'm not sure if it can be resolved though - I was on the phone with MetroPCS for about an hour trying to figure out why my phone wouldn't connect to their network. I know Cyanogenmod comes with APN's pre-installed but even after the representative tried helping me set up a new APN .. it was a no go, so I switched back to the current phone I'm using - Alcatel Idol 3 4.7 .. anyways, I'd like to hear your input on what the issue could be as I'd really like to go back to using this phone since the software aspect is far more flexible with a custom ROM like Cyanogenmod.

Are you talking about connection to their network altogether, or just data? Do you have reception? Check that data is enabled in Settings -> Data usage.
I can guarantee that this is a software issue, BUT one last question. How old is your SIM card? There have been a few cases when people have been in the same situation as you, got a new SIM, and that fixed the issue. You could do that, or flash another ROM. CM12.1 is beta, so bugs have to be expected, and it's far from a solution if you plan to just flash something and use it for a longer period of time. If you want something very stable and stock, then highly recommend Scrubber's GPe 5.1 port, which is rock solid.
Well my sim card isn't too old, had it for about a year. Once she laced the sim card to the new phone I could make calls and texts but for some reason the Internet wasn't working - she had me go through all the steps to make sure things like data was enabled and airplane mode was off but it still resulted in not being able to establish a connection to the web. So I'm gonna try and flash the GPE rom you're talking about later on tonight once I get home from work and see what happens then - mind leaving me a link to the rom/recovery? Thanks in advance.

Sure. Here it is. Remember to download 5.1, and not 5.0. Recovery is included in the ROM, so you don't have to flash anything else.
Quick update, I've flashed the ROM but so far it seems to be stuck in a bootloop, its been stuck on the swaying Google logo for about 10 minutes now. It might be because I sideloaded using a micro SD card because for some odd reason the 'flash the system' option on Flashboot wasn't working for me. So I turned the phone off and will give it another try tomorrow, if you have anymore tips for me I'll be glad to hear em.

How did you flash it? It must be flashed in recovery on the device and not using Flashtool. Flashtool is strictly for stock Sony ROMs or FTFs. Never use it for anything else besides flashing FTFs and kernels. So:
- Go into recovery
- Remember to wipe! If you don't, you'll get a bootloop
- Install from SD card
- It will probably throw an error at you, but don't touch anything. It's still flashing.
- Reboot
- Wait a couple of minutes.

Just did everything you just said, will update you tomorrow with results.
Well I did what you said and left the phone to charge overnight - it was in bootloop when I went to sleep and .. bootloop when I woke up (at least it's charged now lol) I'm gonna try again though. I see that CWM has a sideload option, so I'm gonna wipe everything and try to sideload it from the ADB through the command prompt and see what happens. Feel free to leave any other suggestions though.
Got a question though, when I sideload the zip file should I sideload everything within the zip file or just the system image file? Maybe I'm getting bootloop because I'm installing a kernel on top of another kernel?

Sideload/flash the .ZIP. Do not extract it. You should simply just boot into recovery, choose "ScrubberPortRom_GPE5.1_LMY47D.zip", flash and wait for a couple of minutes and then reboot. That's it. The first boot should take around 5 minutes.
- Remember to do a full wipe in recovery before you flash
- Flash ScrubberPortRom_GPE5.1_LMY47D.zip
- Reboot
And do share any error messages if you get any while flashing.
Hey lovely ladies and gents,
So here is the situation: I have an LG Optimus l70 MS323, which until yesterday was with a stock ROM. I banged my head against the wall, trying desperately to follow a guide and root it, along with trying to unlock the bootloader until I watched a video (in Spanish. Thank you high school spanish!) which used flashify to flash a CWM and boot to the custom recovery. I loved it, since that meant that I would be able to finally flash an official Cyanogenmod OS. The first ROM that I flashed was cm-13.0-20160121-NIGHTLY-w5.zip, which worked and made me feel SO HAPPY (I almost yelled Eurika for the sake of historical comedy). I then went ahead and installed an Superuser-SU binary update through the CWM recovery because I wanted to keep on having root. Then I installed a nano gapps package for ARM, Android 6.0 with some minor complications (mostly the "Setup Wizard" crashing every 2 seconds). I rewiped and reinstalled Cyanogenmod through CWM, flashed gapps on the same go, and made a little backup through the recovery menu. I booted up successfully to be met with that buttery-smooth GUI of Marshmallow (ugh, so good.) I decided to go ahead and fetch some apps from the Play Store, such as Messenger and ROM manager. I saw that the Cyanogenmod Update Center had pushed out a notification that the newest nightly snapshot is already downloaded and decided "Meh. What new features have been added? Let's reboot and reinstall." At that point it was 4:40am (keep in mind that I've been trying to get the goddamn phone to cooperate since ~10pm) and I noticed that the boot sequence takes up a lot longer and told myself "It's probably taking a bit longer than usual, it's normal." I put the phone next to my head, hoping that it's going to be ready to use in the morning.
Fast forward to 8:07 am. Bootloader is still going, phone is so hot it can cook an egg.
GNAAAAAAAAAAAAAAAAAAAHHHH. WHY YOU GOTTA DO DIS TO ME PHONE?!??! WHY!?!
SO, the CURRENT situation:
1. Whenever I press the power button, it starts off normally. According to my definition of bootloop, it's stuck in a bootloop.
After hours of staring that goddamn cyanogenmod mascot do you realize that it's going to boot itself into the booting oblivion.
2. I don't have access to CWM. I have tried holding down the power buttons with godknowswhat combinations (I like to call them the Naruto Jutsu of pure despair). Maybe I should hold the buttons for 2 milliseconds longer and it might work. *Sigh*
3. I don't think that I can use fastbood or adb. My computer doesn't see the phone. (GNAAHHAHASDJFLSKDHFSLJHLKJ.)
4. I am totally clueless about what I should do or try. I've basically softbricked my phone and don't know how to unbrick it.
So, now that you see that saying that I'm frustrated is truly an understatement, what do you suggest I do?
In advance, I'd like to thank you SO MUCH for even giving a sh!t about my problem.
Other misc info: I have a 32GB SD card on which I have all the different tools I have used throughout this journey.
I am willing to have it back on stock ROM. My biggest goal is to somehow boot into CWM recovery. From there on, I will be able to deal with it. Until I come back to this forum, begging for mercy.
Have u tried using LG suite or LGUP u need to go to LG 's firmware page I'm not sure about this phone but it worked w my k7 about 100 times also helped unlock it. Check out the LG k7 forum lots of guys on there that use the lgup program and can help
