Cannot Boot up LG Optimus M

Hello can someone please help me. I have an LG Optimus M and my battery is dead and it is not able to be charged. The only way it does turn on is by connecting it to usb, when I connect it automatically boots up to a screen that says
Fastboot mode started
gpio_i2c: invalid khz: 0
b1: i2c write error
udc_start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
and the other option that works is going into emergency mode by pressing Vol+/- back and plugging the usb cable. When I do this I go to a s/w upgrade screen with LG and metro pcs logo. I would really appreciate it if anyone would be able to help me just turn this phone back on..

Hello, I'm sorry you have that problem and my heart if crushed. I would be devastated if that happened to me.
But hopefully this will fix your problem.
I will now teach you how to do a factory reset on your phone this will restore it to factory settings and will unroot it and will bring back all your metro installed aps leaving your phone good as new.
So here is what you do. Shut down your phone. Tnen make it turn on BUT as its turning on hold the Top button on your phone and the volume down button and the home button all at once just keep holding it until you see some thing diffent happening to your phone. You will see a Box open with the little android next to it. once you see that wait a little bit then let the buttons go.
Then patiently wait for your phone to restore itself. (can take as long as 5 minutes) if it works the phone should be good as new. But all your apps will be gone.

can you please make an instruction video of how you do it becuse when my lg optimus m is on fastboot mode it shows this i was rebooting my phone to original factory settings and this started i need help anyone!!!! IT IS ROOTED
fastboot mode started
udc_start()
it is dead and it wont charge!!!

I have found a solution to fix a lg optimus m I dont know if it works on other lf ir works on other lg optimus but the direction are to have a wall charger and your optimus m first connect your charger into phone without battery in the phone and make sure the phone is off at first
Now when your phone says battery required get your battery and keep touching the part of the battery that is gold with the gold part in the phone. keep doing this constanly as the lg logo goes on and off for about 10 times and then put the battery completely and then it should go to the charging image if it doesnt do that then email me at [email protected] for questions

Fighting a lost cause?

I've got a rooted (Super SU, but the original root manager was Superuser) LG C800 that I was having problems with. To be specific, I installed some apps on to the system. Some of these apps would be Titanium Backup for root, Avast Mobile Security, ROM Tool Box Lite, Super SU, and a quite a few others. From day one they seem to be kicked right back to my S.D. card, but not all at the same time, and some would stay on the system. I read where I should move the apps back to my S.D. card and try to re-install them on the system minus the data. When I did, the phone went nuts. Now it stays in a restart mode but never fully boots up. Can I salvage it, and if so, please tell me how?! I have tried the hard reset/recovery boot where you hold down the power button, volume, and a few other keys, but it did not work. I'm a broke college student and can't really afford to buy a new phone. I used this one for everything including tethering it to get my assignments done at home and turned in on time. Please help! I'm open to suggestions....... My phone will be completely off. When I plug it into my computer, via U.S.B., it automatically turns it on whether I want it to be on or not. Then it starts off in "reboot recovery" mode, will boot all the way to the point to where the home screen would normally turn on, but then it starts in that "boot loop" all over again but never fully boots up before going back to the beginning of that "boot loop" yet again. I can't even get it to register on my laptop as being plugged in. The reason I took the apps I placed on the system off was because sometimes when I'd re-boot the system the apps would be on the system and sometimes back on my S.D. card without my involvement of any kind other than rebooting my phone. Is completing a Nandroid recovery or re-installation of my ROM even possible with my computer no longer recognizing it as even being plugged in? From what I can tell it won't be. Am I fighting a lost cause or is it salvageable?
Rooted myTouch Q 4G, a.k.a. LG C800
I believe it has a 2.3.4 GRJ22-perf, and then something like 2.6.35.7? I can't remember off the top of my head, and I can't pull it up on my phone anymore or else I'd double check.

Have you tried booting into recovery?

(More about my phone from the original post) Honestly.........I'm not what you may consider technologically inclined. I have however done about as much research online concerning this matter as any one person can do. I've looked it up on all major sites, and many smaller ones too, that post remedies for phone, or "human" if you'd rather, malfunctions. They all talk about still being able to reach a home screen or doing the whole holding the power and volume decrease buttons until I "reboot recovery" screen appears (if that's what you're referring to as doing a recovery reboot as). Don't forget the one where you hold hold the power and volume decrease buttons along with the "A" and "F" keys as well. I even tried one from here where you're supposed to push the genius button after the Android figure leaves the screen. My phone won't allow me to do either. Basically if it's online, I myself, or this girl that's been staying with me, have tried it without any results. On the initial boot the Android figure and the box with the arrow coming out of it show up and it boots until just about the point that it use to switch over to the home screen and it will start the whole "boot loop" over again. The thing is though that the Android figure and box aren't there any other time after the first boot, and with every boot loop it makes after that, the time is reduced from the beginning of the loop to the end when it starts all over again. The phone won't shut off unless I remove the battery and even though my laptop no longer recognizes the device, when I plug my phone into it or another power source and it's off, it automatically turns itself on and begins that boot loop all over again. there is one thing I have yet to try. I read on one site where I could download a custom ROM on my S.D. and then try reboot it, but it never makes it to the point in which the files on my S.D. card are ran, much less scanned. I am still 100% open to any and all suggestions in the diagnosis of this issue. I may record and place a video on one of the more popular "tube" sites to better show or further explain what's happening and then come back on here to post the link?! Feel free to reply back if it's possible you can help before I'm able to complete that later this evening. And thanks for any and all help in advance to everyone.

Moto G unresponsive

Looking for a quick fix here as I can't go to the service centre and get a replacement until at least Tuesday, and I need my phone working before then. I'm hoping someone else has had the same problem and can help me out.
My Moto G froze and became unresponsive (while I was refreshing my Gmail inbox) and it would not accept any input. I held down the power button and the power menu opened, however when I tried to power it off, it wouldn't accept my touch input. So obviously the next course of action was to hold down the power button for 10 seconds to force a reboot. The Motorola logo appeared and the phone vibrated... then it did nothing.
I tried this a few times and still nothing happened. I am able to boot into the bootloader, but apart from that, the phone goes only so far into the boot cycle before the screen goes black and does nothing.
Motorola's website suggests that if the Moto G becomes unresponsive, and the regular 10 second reset doesn't work, you should hold the power button for 120 seconds and keep it plugged in to a charger. This didn't work either. As of right now, my phone is just sitting here on my desk with what I would call a 'black screen of death.' Help would be appreciated.
I cannot boot into recovery, I cannot access anything. The phone is stock, unrooted, and running KitKat 4.4.2 without any modifications whatsoever. It's about 5 months old now, so it's still covered by warranty and I don't want to void it.

Can you boot into bootloader mode and use adb command from a pc? If yes, maybe you can try to flash a stock recovery img file via your pc to phone.

Would that require unlocking my boot loader though? I don't want to void my warranty, especially considering I did nothing to the phone and it's currently unresponsive.

I am not sure - but my guess is that bootloader needs to be unlocked to install custom recovery to "recover" & backup userdata before flashing the entire original stock firmware; that's usually the first step we see in all those modding guide in different forums online.

I suppose you can also contact motorola support to see if they can help you recover your data before getting the phone fixed or replaced under their warranty program.

Help with LG G3 Turns off During Boot & Unable to Factory Reset (is it a lost cause?)

Help with LG G3 Turns off During Boot & Unable to Factory Reset (is it a lost cause?)
Hello everyone. This is kind of a complicated issue, and I would love any help I can get.
Back story:
I have a Verizon LG G3, purchased in December of 2014. I never rooted the phone, so it has been stock this whole time. A couple of months ago, the SD card holder randomly stopped working (no spills or drops). I tried multiple, new SD cards, formatted them and everything, but the phone just kept ejecting the SD card, and corrupting them, so I just gave up on it and stopped using an SD card in the phone. This is not the current issue at hand, but I wanted to preface that I've been having issues with the phone.
Fast forward to a month ago. I had my phone plugged into the wall charging, and was not using it. I noticed out of the corner of my eye that my phone turned off. I unplugged the phone and tried turning it back on. It showed the LG logo screen, then the verizon screen, and then just turned off. When I tried powering it again, it did nothing. I pulled the battery, put it back in, and pressed the power button. I got the same series of lg logo, verizon logo, then off. I thought maybe it was a battery issue and took it to a local phone repair shop. They put in a new battery, but got the exact same boot problem I did. I left the phone with them, and they took it apart to see if it was a hardware issue (and the infamous stuck power button issue). When I returned, they told me that they did not find any hardware issues. It also was not an issue of the stuck power button/power button not working. They decided that it must be a software issue. Their explanation was that the phone had probably tried doing a software update and something went wrong. They said they could only fix it by completely wiping the phone and installing the software back on. I was reluctant to go through with it because (1) I would lose all my data (and I did not back it up, my fault, I know) and (2) it seemed like they wanted me to pay almost 100$ for something I could do at home. So I kept the phone and left it alone for a while. Now, it has been a month since the issue began, and I'm trying to see if I can fix it. Here is what I have tried.
1. Tried to power it normally again, but now the phone won't boot past the lg logo screen (no verizon screen, just turns off)
2. Held down the power button and volume down button, and able to get into recovery.
3. Tried safe mode -> boots to lg logo and turns off
4. Tried wipe cache -> boots to lg logo and turns off, does it twice
5. Tried USB debug -> shows the android icon, looks like its working, turns off
6. Finally tried factory data reset -> goes through the "are you sure" screen; select yes; shows android icon, looks like its working, turns off
7. Tried holding down the up button and plugging it into a computer to reinstall firmware, shows logo and turns off
8. When I plug the phone into the wall, it charges normally. Simply won't turn on past that.
I'm not sure what else I can do to the phone. Is there a way to factory reset from a pc or mac without the phone being on? Will I just have to take it to the tech store so they can do whatever magic they seem to possess? I already plan on never getting another android after the issues with this phone (and many androids before this one), but I need this phone to last until December.
Sorry for rambling and thank you for any help!

LG-G3 VS985 boot certification verify error (Boot loop)

I did search my terms and didn't come up with anything close to my situation, which is this: I got this phone in 2013, rooted it successfully, but was never able to get TWRP flashed properly, but I was happy with the root, so I sort of ignored the TWRP thing. Now I am getting a replacement phone, LG-V20 VS995 next week, so I decided yesterday to tinker around again with TWRP, as I wanted to put this on the V20.
On the G3 when I flashed(Or so I thought) TWRP and rebooted to recovery, I would get an error message (Very small) in the top left of the screen, then would disappear and I would have to pull the battery to reset and then it would boot fine back to the OS, but not to TWRP.
I made sure I had/have the updated Windows LG drivers, ADB, etc.... and I could see my G3 in Windows properly, the internal device and the microSD, I even pulled up the terminal emulator on the G3 while attached to the PC and ran an ID command I think, successfully. I pulled up a CLI in Windows in my ADB directory and my G3 device showed up as well. Then I tried flashing TWRP, first using Flashify; I started with an older version, like 2.8.6, but it didn't seem to work, so I started going towards the newer versions, but still, Flashify kept saying they failed to flash. So I tried the official TWRP app, and it seemed to be doing the same thing. So I went back to review what I had already done, then disconnected my phone from the PC, rebooted normally and tried again with the TWRP app. I think I was successful with one of the newer versions, 3.1.x so I did the reboot after it said it was successful, but I got that boot error message again, then blank screen and red/blue flashing lights; removed battery and replaced, powered on for normal boot and back in the phone OS again. I checked some YT videos on flashing TWRP on VS985 and it appeared I was doing everything correctly, but then I saw this one video that stated to use the Vol+ and Pwr button (I guess I thought when I selected "boot to recovery" the phone was going to do that automatically), then once you see the LG logo, release the Pwr button, then continue to press the Pwr button all while still holding the Vol+ button down, and then you would go into Recovery mode.
His next words sort of came as a shock - you had to select the option to reset your phone to factory defaults, and THEN, and IF you were successful flashing TWRP, it would take you to TWRP. I thought about this and and decided to do another TWRP flash, and if successful, would try this method. I did and I was able to get into the stock recovery menu, and I did see the option to "Reset phone to factory defaults", but decided just to cancel and went back to the phone OS, and that worked. Later on, I decided to try the "Reset" option on another phone boot, but I've now run into a different issue/error. When I boot the phone, I immediately get the error message (The boot certification verify error), and no matter how many times I remove the battery or for how long, each time the phone boots, I get this error message. The only thing I have been able to do is get into the Hardware Key Control Mode using Vol+Vol-Pwr and just continuing to press them. No matter what option I choose, either Cancel, Mode On, or Mode Off, the phone immediately reboots to the error message; it's like it's stuck in the Recovery boot mode somehow. I'm not sweating it too badly, as I've got a V20 coming next week and I have a work cell I can use for important things, but has anyone run into this type of thing? The way it is now, I cannot view the phone on my PC and cannot seem to get past this boot certification verify error.
EDIT: I am now able to consistently boot into the System Recovery by way of Vol+Pwr button held down until the SR menu shows. HOWEVER, no matter what choice I select, phone reboots and I get the "Boot certification verify" error................ oh well, at least I got an email that my V20 is coming this Thursday.
EDIT: I must be somewhat dyslexic, as the method to get to the SR menu is VOL- (Not Vol+) and Pwr button held down until SR menu entry. Sorry about that
EDIT: I've also seen the "fix" where you remove the back cover, battery, and then remove the top plastic cover over the battery/power/volume, then also remove the metal shield. This is the point where it gets confusing; the author(s) want you to "ground" 2 of the contacts, but it's not clear which ones they are referring to, even with the screenshot, and I'm not electrical engineer, so not exactly sure what they mean by grounding. As I'm getting a replacement tomorrow, I decided not to even explore this technique, although I did dissassemble the phone down to removing the metal plate, so I could try and see if I could figure out what they were talking about (I couldn't). Gotta say, I've had my G3 for over 7 years and for the most part, really loved it; it came in handy during home power outages when the Internet (Cable) went out.
