My Moto g2 was on stock rom with no root. A friend tried to root it with king root and some other things without asking me . My phone ran out of charge and then when i tried to switch it on it went straight to ap-fastboot menu. Now, when i connect charger it shows charging screen at 0% and then goes to fastboot after some time. With some things written.
It says at the end :
1. Hab check failed for boot. 2. Failed to verify hab image boot. 3. Failed to validate boot image 4. Fastboot reason : fall through from mot charger boot mode.
Also it says battery low Device is LOCKED Status code: 0 and connect USB data cable even when connected.
Also i can't install usb drivers as my pc doesn't detect it once did but the Dialog box of "installing drivers" vanished midway.
So my phone won't charge or connect to pc so i can't use some adb and fastboot tool method for charging i found searching on the internet. And also it keep going from fast boot to charging screen and back Been searching all day but have become confused now.
So if someone can help in flashing my stock firmware bypassing all these problems. I'll be thankful.

I have searched around for a couple days, but there doesn't seem to be anyone who has posted about this issue with a Droid 4. So here is what I have.
I rooted my Droid 4 using the RazrBlade method without incident. Afterwards I wanted to flash Cyanogenmod onto it, but did not have a custom recovery like ClockworkMod or TWRP set up yet. So, looking around led me to download the latest safestrap .apk so I would have a recovery capable of flashing Cyanogenmod. The latest version of safestrap would not work for me because of a parsing error, I looked around and found that some people were having the same issue and fixed it by downloading an earlier version of safestrap to their Droid 4. So, I found a safestrap 2.x.x version, downloaded that and followed the directions accordingly. I now had a functional (to my knowledge) recovery that would allow me to flash CyanogenMod. So I downloaded the .zip file from the CyanogenMod website for Droid 4, and attempted to flash it using the recovery that safestrap 2.x.x set up.
Everything looked okay for the install, no errors were reported, phone was at least at 80% battery, but once the phone rebooted, after the Motorola spash screen, there was a blank screen. The phone is on, evidenced by the backlight being visibly seen, but otherwise there is no evidence that it is trying to boot up any ROM. There is no loop whatsoever, just a blank screen.
First, I thought it was a bad install, afterall, it wouldn't be the first time. But when I turned it off (only possible via PWR&Vol.- button combo) it did not give the option to go into the safestrap recovery mode upon booting back up.
But I am not without a working knowledge of how to pull a phone out of a softbrick state, so I quickly connected my phone to a computer set up to take adb commands and tried to reboot my phone into the recovery mode. I connected my phone to my PC, left it on the blank screen mode and typed the adb command [adb devices] to confirm that it was acknowledged by my computer, it was, and attempted to reboot it into the recovery mode with the command [fastboot reboot-recovery]. It responded by rebooting, but led back to the backlit blank screen. I thought that this might be an issue with the wires or drivers or something to that effect, so I reattempted with a usb cord that was supplied by Motorola, and reinstalled all the appropriate drivers. Nothing worked, so I moved everything to a new computer freshly set up to take adb commands. I connected my phone and it was immediately recognized by the new computer, but it still would not respond to any adb commands. Attempting to reboot into recovery yields a blank screen still.
By this point I do not care if my phone is rooted or if I have to restore it to factory settings. So I look up solutions that flash it back to the stock 4.1.2 ROM. I find one that does this, but it requires that I am in AP Fastboot Flash Mode. I put it in the aforementioned mode, but it is not recognized by the adb terminal. It is listed as an adb device if it is in "blank screen mode" but not while in AP Fastboot Flash Mode. Shortly after this the battery is too low to program anyway, so I turn it off and set it to charge. But instead of a "battery charging" screen, I am greeted with the Motorola splash screen for as long as the phone is connected to the charger. Every time the phone is removed from the charger it, immediately and without pause, loses power and cannot be powered on until placed back on a charger.
Looking around some more, because I am increasingly desperate to solve this problem, I find something called RSD Lite, which will reflash the stock firmware to the phone and it will behave as if it was reset to factory settings. I plug the phone up to the computer, it powers on, I boot it up to the AP Fastboot Flash Mode and RSD Lite sees the phone as a fastboot device, and is ready and willing to fix it, but the battery is too low to program.
The battery is incapable of being charged by a wall outlet by any means that I have tried (will list below), BUT... If I connect my phone to a computer, and after the phone is connected, turn the phone off, a little green LED light appears at the top left and stays for at least 15 minutes until the Motorola splash logo appears and my phone connects to the computer. The phone recieves power in this mode evidenced by the fact that it does not instantly power down after it is disconnected from the power source. But at this point in time, the battery does not charge enough to cause a change in the AP Fastboot Flash Mode to allow it to be OK to Program.
Here is some misc info that might be needed:
Modes that I have access to
1.) Motorola Splash Screen + "Blank Screen Mode": This mode connects to the computer and is registered by the device number XT894. After the Moto Splash Screen there is a backlit blank screen I call "Blank Screen Mode". This mode is recognized by adb commands but not by RSD Lite. Any time an adb command is used apart from rebooting, command prompt says <waiting for device> and the device does not respond.
2.) Motorola Splash Screen Only: This mode is only accessible by connecting the phone to a wall outlet. This mode does not charge the phone and if the phone does not have any power otherwise, will power down without warning upon being disconnected from the power source.
3.) Boot Mode Selection Menu: This mode provides various options that appear to do nothing. The "Recovery" option that is supposed to bring me to the default android recovery mode instead brings me to the Motorola Boot Logo and then to a green android laying down with a red triangle over it (with an exclamation point). I am able to access AP Fastboot Flash Mode from here.
4.) AP Fastboot Flash Mode: In this mode, the device is recognized by the computer as an adb fastboot device (not as an XT894 device). It does not respond to adb commands, and the adb terminal does not acknowledge the phone in this mode. RSD Lite does acknowledge the phone in this mode, but trying to begin the process to reflash the stock firmware causes the "Low Battery/ No Program" text on the phone to flicker and result in a failure in the RSD Lite program. It lists the reason as: Phone return(ed) Fail.
5.) Computer Charging Mode: When connected to a computer, and immidiately powered off, a green LED light turns on. After leaving the phone for some time, the phone can be disconnected and stands on it's own power without needing to be connected to a power source to remain on. In this mode, the screen is not on, and the phone is not recognized by the computer at all.
Methods I Have Attempted to Use to Charge Phone
1.) Plugging Moto Stock USB charging cable to computer and leaving it: This causes the 1st mode listed above to occur, and no charge is held. After 10 minutes of "charging" upon disconnecting cable, phone shuts off abruptly, and without any warning.
2.) Plugging Moto Stock USB into USB to Wall Outlet Plug: This causes 2nd Mode listed with similar results to above.
3.) Plugging Motorola Wall Outlet Charging Cable to Phone: See above
4.) ALL Above Methods + Boot Mode Selection Menu BD Tools Mode: I read that if you were to connect your phone to a wall outlet after booting it up into the Boot Mode Selection Menu, and selecting BD Tools, the phone would boot up to the Motorola Boot Logo screen, then show a battery charging similarly to how one does if you charge your phone after it shuts down from having 0% Battery. This was not the result I received. Similar results to #1
I apologize if there is some blatant simple answer here, but I have looked everywhere to find a solution to no avail. I included everything that occured between then and now so as to facilitate this process, and hope that I am not stepping on any toes with the wall of text I just posted.
Thanks in advance, if more info is needed (or if the post needs to be formatted in an easier to read way) just say so.
Sounds like you will need a motorola factory cable. I think that's what they are called. It provides power directly to the phone allowing you to fastboot. I know you can find them on ebay. I believe team black hat also sells an adapter to turn your regular OEM cable into a factory cable.
Your other alternative would be to sacrafice a usb cable and attach to the battery terminals directly to charge the battery. If you google it you should be able to find directions for how to do this. I believe someone posted a how to on youtube for the razr which should give you a good idea of what you would be getting into.
Good luck!

Fixed It
Thanks for the help.
I didn't feel like paying $12 dollars and waiting several days to purchase one of those special factory cables, so I ended up taking a non-USB charger, spicing it, and hooking it directly to the battery terminals like you said. After I did that, it automatically said that it was "OK to Program".
The only problem I had was that RSD Lite wasn't able to fix it, I had to download some other app that ran things through command prompt while the device was in AP Fastboot mode. But the end result was the same.
I found out that the problem that caused all this was me not flashing the CyanogenMod firmware into ROM Slot-1 while in the safestrap recovery mode. I flashed it to the "Stock" ROM Slot instead.
Thanks again for the help, I learned a lot, and I am glad I didn't have to shell out money for a new phone. :laugh:
Long time ago, my phone had the usb host mode problem when plug in into pc, but can charge at OS. So i didn't bother it because it still can transfer files to PC via USB OTG.
Last month, itself random went into usb host mode when charging and the phone totally cant charge, need to restart then its ok. When i go into fastboot it shows FASTBOOT AC and then FASTBOOT randomly (like gotten shock) and after awhile the problem gone so i didnt bother about it.
Last week, I unplug my phone after i wake up and then itself shows USB HOST MODE, so i tried connect USB OTG and then it didn't works. I thought it was kernel problem so I downloaded ElementalX 18.2 and then i flashed it. Now, after boot, the phone wont charge. It only charge when powered off and RECOVERY mode. Fastboot shows no sign, no FASTBOOT AC or USB, even OTG power. This is strange and weird.
Also, i flashed ARHD 81.0 at older version of TWRP Recovery, and then after i got that problem, i reflash my phone with TWRP 2.8.0.2, at the end it says : "set_metadata_recursive some changes failed" , and the phone can't boot. Luckily i got a nandroid of it so i flash it immediately. It can boot, but the no charging problems still exist.
I later upgrade my TWRP to 2.8.3.0 via TWRP Manager, still get "set_metadata_recursive some changes failed" problem. But, I found out that after i flash the rom, then flash nandroid, when i boot into OS with charging, it can charge in the OS, but not anymore after i went into fastboot or recovery.
And something interesting is, when the phone boot, haven't load the drivers, itself began OTG mode and powered up my powerbank, PLEASE HELP!! Im totally stuck on this!
Does this is a hardware or software problem? Its this the USB board broken or the motherboard? Please respond..
Sorry for my bad English.
I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer

My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[
Hello, I tried to flash kitkat, I run flashtool and start flashing it but after a while in the middle of flashing it says device disconnected. After that if I connect it to my PC in flashmode it says it has a problem with this device, I can see it in the device manager as an unknown device, device ID is USB/UNKNOWN, fastboot mode says its a sony ADB interface but when I click on it it says it cannot run this device, the device ID is USB/VID_0FCE&PID_0DDE&REV_0100. Is there any way I can repair it? If I try to power up my phone the sony logo appears and it says the software update failed. If I connect it to charger its the same, no battery appears. If someone know how to rescue it please reply, I buyed it yesterday and its already broken
Now I check it on flashtool, after I connect the usb while pressing vol up button it says device connected in fastboot mode but when I click on check current device status it says device status: not found, also get device info says this action can only be done in fastboot mode
And now my PC doesn't notice if something is connected, no device problem pop up, just nothing. Now when I connect it to the charger the led flash red one short time and nothing
EDIT: now i charged it for a while and PC see it again, on charging bootloop with software update failed
Try to flash stock firmware with flashtool and see if it even recognizes it.
Hello everyone. I am in real trouble here and I will explain why. I have recently tried to get the custom recovery with a locked bootloader (philz touch) on my device by following a thread. As far as I know I followed the guide properly but when my device rebooted it bootlooped 10x and then when my device booted it froze at the lock screen and restarted. now my device bootloops several times before boot and once it boots I get 1min at the most before it freezes and restarts. Also sometimes it fails to boot at all and it gets stuck in an infinate bootloop and I have to pull the battery. when I connect it to my laptop with a usb cable it is only recognised if the device boots but I only have a few seconds because the phone reboots and disconnects when I try and enter recovery or download mode my screen goes black and the only way to get of this is to pull the battery. I have also tried to connect to my laptop when on this black screen but i have had no success. If I turn the phone off and connect it to my laptop via usb when I am on the "battery charging screen" it appears on my computer as a unknown usb device. i do have all the drivers ect. my device is rooted with baidu root if that helps. ive heard of a little device called a usb jig would that be useful to me? sorry if this is not worded very well or looks like a book. Im not a idiot but not quite "tech savy" i would like to think i am somewhere in the middle. I have been using this site for years for various devices and always managed to succeed. help would be apprecited. Thanks
UPDATE: I have tried to factory reset from the settings but for some reason the button is greyed out and it wont let me press it! also I cannot connect to wifi or mobile data these are greyed out aswell and when I try to connect via the sliders in the settings menu they are also greyed out!!!

Hi, you need an unlocked bootloader for it to work properly. You can find how to unlock the bootloader by going to Sony's website and see where it says to unlock the bootloader or just look for it on Google. To get back to the stock rom (Android 4.4.2 KitKat), you will need Flashtool and the stock rom. You can find the rom on Google by just typing "sony xperia e1 d2005 stock rom". To get the recovery just try looking for it on XDA. And USB Jig will not work for Sony devices. USB Jig is only designed to work with Samsung devices.
