How to unbrick a "dead" Milestone.

After an unfortunate rooting session with my Motorola Milestone, the phone now returns into an "dead" mode. It refuses to start at all. I tried charging it and see if it starts by itself, but it doesn't budge and the little while led doesn't lit. The only time when it lit is when I connect it to the PC. I tried putting in it a new battery, taking out the SD card and SIM, but to no avail. I remember seeing a video where a guy used a dissected USB cable to spark the phone into turning on again, so I take it I'll have to use a "hardware approach"? Please help.

I tried following this guide, though without success. The phone still has that white LED lit when it's connected to the PC.

After a reply on this thread I also made, it might be possible that the battery is charged, but the phone refuses to boot at all. Is there any way to unbrick the phone in this state?

Do you think your device is really BRICKED?
If so, you can try to flash your original sbf file into your phone. Guide here: http://forum.xda-developers.com/showthread.php?t=696845
If you are using a Linux, google for "sbf_flash".

I agree with my front floor..ermm, u dont need to worry about its 'dead'. just flash original sbf can rescure your phone.

I had the same problem too, but good news is I tried to revive my phone successfully recently, btw your phone is not 'dead', it's just staying in limbo state, the solution is to pull out the battery and don't connect to any usb, don't try to power it up, it must be completely out of power wait about 12 hours, and then try to power your phone, I think there is some capacitors in the phone which retain the phone state, to make it out of power will wipe out it's state, good luck

"My phone is in limbo state... "
That's a pretty cool statement.
From technical view, it might have happened that something caused a kind of deadloop when reading scratchpad SRAM inside OMAP processor.
This SRAM, as well as the internal RTC is powered by a small battery soldered on the mainboard, while the phone is shut down and the battery is taken out.
What you did was, to wait untill this battery became uncharged.
All SRAM and RTC setting as well then gets erased.
Afterwards the CPU will start up with empty scratch SRAM, might be called a "real" cold boot
Normally the phone should not behave like this. Even if SRAM is not valid the phone should boot up...
...but anyway as you observed it like this, it might happen.
@andoruB:
Apart from that, the Milestone is hard to brick in general.
Might happen though, if you do evil things while flashing new firmware.
Especially while flashing bootloaders...
If you got some more information about the things you did, would be helpful!
Good luck anyway!

how did u root it? can u give a more detailed description? and hows ur phone? sometimes, the milestone would just shut off and wont come up if the battery is gone. Try charging it for maybe 2-3 hours, untouched, and see what happens.

Have this exact problem. Was doing a nandroid recover when the phone got stuck. Pulled the battery out. Placed it back in, pressed the power button. Nothing.
Led lights up only when connected to the computer's USB. Battery was charged before Nandroid recover. Used nandroid a lot of times but for some reason, my stone stopped playing nice.
I just removed the battery. Hoping this works. Can someone please post if you got this same issue resolved? I like this phone no matter how slow it goes sometimes. Thanks!

I completely forgot about this thread, sorry guys!
I don't remember exactly what happened, it's been so long... but I do remember I left the phone "inactive" (it's not like i had much of a choice! XD ) for 1 or 2 months, with the battery out. After I got hold of a wall charger, I plugged in the battery, after I plugged in the charger, and what do you know? It worked! It started charging (was 60% charged, fully charged, I unplugged it, but after putting it to charge again just to make sure it was fully loaded before I would flash a new ROM, it was charged up to about 80%, weirdly, so I guess it was a weird battery problem)
I do remember I didn't do anything to it, so I'm not sure what to tell you guys to do, except leave out the battery for a month or so ^^;

[Q] [PLEASE HELP] HTC One M7 not charging when on.

Device: HTC One (M7) Stock ROM
A few days ago, my never rooted, stock firmware, no unlocked boot loader, no custom ROM, never dropped HTC One (M7)'s battery died. Plugging in the charger had no effect, absolutely NOTHING. Tried 6 different cables and 9 different locations to charge it, nothing. Waited a while, dying in desperation. Then after so much of panic, I plugged it again, and randomly it started charging. But the charging had a loop - showed a bright orange LED with the power symbol on a battery for about 5 seconds, then a dim orange LED with the green battery charging, and a number, for about 10 seconds. The loop kept repeating. Eventually I could turn it on till the (incredibly low capacity) battery could live. So I did about 10 resets to it, and the situation would not improve.
Since my phone just decided to do this to me just before a long journey of mine, I was quite upset, and eventually infuriated to the limits. I decided to take it along and try different things to it - tried, tried, cleaned the ports, searched the net, nothing.
One fine day it decided to break the loop - now it charged, but only when off.
And today again its started the loop.
And here I am, begging for some help. I'm starting to hate this device now. Please help me.. :crying:
P.S. : I played a lot of Clash of Clans on the phone - it heated up a lot. Hope the info helps (Possible corrupted overheating charge instructions of the phone,etc.)

please help i love this phone cant lose this at all

I am having the same exact problem right now. its very annoying. I have to drain the whole battery to charge it again. and its in that loop that you mentioned. plus it does not charge when you put it on charge when its on. it doesnt even have that charging light. it only charges itself if its off and if there is no battery left, i have to put it on charge by draining the whole battery by using apps and stuff and i am so pissed right now i cant find a solution to this. Did you find a solution on how to get this fixed?

I am currently having a similar problem where I can only charge my phone if off. Hopefully someone can help!

I have found a solution to this. I am really happy since i am able to use my phone again.
Let me state what exactly i was going through.
I had to use the phone till it actually turned off completely consuming the whole battery and it was very frustrating because i had to deliberately use the phone till the phone shuts down and charge it. And once it started charging, it has a weird stupid way of charging. It shows that its charging and it goes off, comes back on and shows its charging, then it goes off... When it goes off the red light goes away...then comes back on.
I've read other threads and forums about people having the same issue. Others say they're not even able to connect their phones to the computer. You all should try connecting your phone to a computer and check if its able to transfer data.
If that happens, then you're saved. Because this really worked out for me.
Now, i'm not really sure what kind of bug this is, but here's how you fix this.
If you're able to transfer data to your phone, you must browse your phone on the computer and copy a file (or a couple of files - in my case i transferred a movie folder that had a couple files in it)
And guess what..i put it on charge and started charging like normal oh my god i was happy as hell
Thanks. I hope the same works for you all, people have been saying you have to clean the charging port but not really

I have the very same problem, my phone will only charge when the battery is completely drained, now i have like 25% and tried your way, my pc doesnt detect the phone :/
I tried with and withouth usb debug mode. :crying::crying::crying::crying:
Is this a sotware problem i guess? it wouldnt charge at all if it was hardware right?

I'm not sure how are you NOT able to get it connected to your computer. Since i connected it to the computer, it didn't start charging but it allowed me to transfer files. And so i did. You might wanna change the cable and check if its letting you connect to your PC.
So far its working perfectly alright. I don't have a problem as such. And wait, you could install a file manager and move a couple files around. Maybe delete some files or download some files and try.
I Hope it works for everyone who's getting this problem. I know its not a hardware problem and HTC support sucks BIG time. i don't even have htc headquarters so i couldn't get it replaced, bad. but if your phone is under warranty you must get it replaced :laugh:

Hi! so you are saying that if i move some files from the computer to the phone it might get fixed? Well, i cant plug it to the computer, it just doesnt recognize the phone, if i plug it when the phone is on the pc doesnt show anything and the phone doesnt charge or anything, just like when trying to charge it with the ac charger, if i plug it with to the pc with the phone off then it shows a message that doesnt recognize the device, and the phone doesnt even charge aswell...
Right now the only fix i have found is to solve the problem of having to drain the battery in order to charge the phone, now i fixed it unticking the fastboot option in energy, now i can charge with any % but the phone must be off. Btw it gets a lot of heat while charging it this way... idk if its normal, i heard that because the aliminium case it gets more heat than normal plastic cases.
Thanks for your reply, ill try to connect the phone to the pc a few more times.

Hello guys , , I have the same problem , charging the M7 (On stock rom), I have tried many things ,roms and kernels , currently I managed to make it charge with the screen on with some conditions..
I installed SLIM ROM from their site (4.4.4) . To charge the phone with screen on I have to check "screen on while charging" (because if the screen goes off it stops charging /same thing if somebody is calling me )
To Charge my phone I just need to Reboot normally and charge it ( if you install this rom Activate the sound for the ac plug/unplug so you can know if it is charging well or not )
Eaven if i have to do these things its better then the OFF mode .
Hope It helps .

HTC M7 Only charges when it's off and the laptop can't recognize the device.
Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

It can sometimes be caused by a defective usb port on the phone, does your port looks damaged? Boot your phone in safe mode and check if its doing the same thing.

I've already done that and it doesn't work.
I really don't know what the issue is? I mean this is a perfectly working unlocked HTC M7.
I've turned if off multiple times and even wiped it clean twice. I don't know what else it could be.
I mean it's been working perfectly since I got it.
But as I mentioned earlier it will only charge while the phone is off. And my laptop can't recognized it either.
It only appears and "Unknown Device."
But even when it is off it charges for a bit and then it completely stops.
Then you see the battery logo and then it starts charging again. But it repeat that same process throughout the whole time. So, it can never reach to 100%.
As I've mentioned before I've never really had this problem.
I've been looking for hours on the internet and so far nothing seems to work. There was an app I saw on to access engineer mode or something, but for some reason I can't use that app because it says that I'm missing another application.
Any thoughts??

I have the same problem, it can't charge, PC don't recognize when the phone is on android, but when i boot into recovery everything work fine (charge or data move to PC), so far i could't find any way better.

Hi,
had same problem.
Clearing system cache helped in my case.
Related cause for the trouble seem to be a couple of OTA upgrades I did recently.
(I was on a pretty old version.)
I noticed that there was something wrong while upgrading.
Even though the phone was connected to the charger while the whole upgrade process,
battery level went down...
The following procedure is your own risk!
Be careful not to choose any options that wipe all your data or factory reset your device.
This is how I cleared the system cache :
Boot into recovery (hold both volume-down and power buttons for ~30 seconds until menu shows - )
Press volume-down to choose RECOVERY and press power button.
Be patient ~60 seconds until menu appears.
Choose wipe cache partition and press power button.
Choose reboot system and press power button.
I hope this helps you.
Thanks

[SOLVED] USB Host Mode problem

Hey everyone,
Yesterday I tried to charge my HTC One by connecting it to my computer. It never had any problem charging up before.
When I plugged it in, my computer connected and then immediately disconnect my phone, when all of the sudden my phone showed up the message "Phone is in USB host mode - Unable to charge phone while in host mode". I must repeat what I wrote: I never had this problem before until yesterday.
The only way for me to charge my phone is by going into recovery mode, wiping cache and plug it into AC power.
I don't know what's the problem and I sure can use any help of any kind.
Thanks a bunch in advance

first of all, the only 3rd party cable ive found to work with HTC is some Samsung device cables, the layout of the cables which is usually 4 or 5 sometimes more inside the actual cable itself is different, never known a Sony cable to work, they are not built to be universal across all phones.
Basically inside the HTC cable you will have 5 volt+, 5 volt-, data+, Data- and usually some sort of ground, plus surrounded by a foil shield, then plastic coated which is the cable you see.
With it charging on AC just means your 5 volt + and - is ok, doesn't mean the data is ok, it couild be shorting out or anything if its damaged.
Worst case its the charging port in the phone, so I personally would try the cheapest option first.

So.. what are my options? The way I see it, I have 3 options:
1) Use a Samsung charging cable
2) If step 1 fails, repair it at a local repair shop
3) If step 2 fails, keep charging it for life on AC power
Though I don't understand: is it for sure a problem within the phone and has nothing to do with computer drivers? I just want to make sure that if I have it repaired I might as well get all the information I can get

try a new cable first, they cost penny's, sounds more like the cable to me as you said in your first post your computer picked it up at first and then suddenly changed to AC mode.

My computer never "changed" it to AC mode, it's just that I can only charge it using AC power

UPDATE:
Tried to charge with my computer using a Samsung Galaxy cable, didn't work either.
Does that mean I have to take it to a repair shop?

I had a similar problem and i thought my htc had gone defect in the usb port. but for that to happen i needed assurance it was not a pc usb driver/software related issue.
when i installed and removed htc sync manager my phone no longer showed the internal storage. and plus i plug in all sorts of usb drivers and pens to PC
so i formatted my pc to a clean start. plugged in htc one and it worked straight away showing my internal storage
my advice is dont install htc sync manager...it has a habit of messing up the port software wise.
so do a format of your pc or plug to a another laptop/pc or friends laptop/pc

Dead battery bootloop

This morning my Teclast X98 battery was down to 5% in Android. I shut down the tablet and connected it to a charger. The moment I connected the tablet to the charger the tablet started to boot. It showed a red charging battery overlay and shut itself down again immediately. The tablet ended up in a bootloop from which there is no escape.
I've had this same problem once before. A couple of weeks ago I somehow managed to get the Tablet into BIOS settings, boot into Windows and perform a shutdown from there. When I shut down from Windows the tablet wil stay off when I connect a charger.
No such luck this time. After 50 or so reboots, with me trying to get into the BIOS settings, the pattern changed. Instead of showing the red battery overlay, the tablet would show warning messages that it could not display the red battery overlay:
ConvertBmpToGopBltofBATMonitor failure
GraphicsOutput -> Blt failure...
One thing that complicates this is that my tablet will not charge anymore when powered on. It only charges when powered off. So it now toggles between: Powered off and charging / Powered on and not charging. It's a known problem when you've used a USB OTG charging hub. Read the comment section on that YouTube video. That guy has tried everything (and so did I).
What options do I have right now?
Leave the tablet in this bootloop, hoping that it will eventually stop booting and start charging
Contact the seller, report the problem and ask for a solution
Take the BIOS chip out and try to charge the tablet without BIOS chip

I managed to get out of this boot loop.
I opened the tablet and unsoldered pin 1 of the EPROM. This prevented the tablet from booting, but it would still charge. I charged it for a couple of hours, soldered pin 1 of the EPROM back and I am now using the X98 again.
If anyone needs some more information, I will search for pictures and write a tutorial.
I still have this problem where the tablet starts automatically as soon as I connect a charger. This only happens if I power off in Android. If I reboot to Windows first and then power off everything is fine. If anyone knows a solution to this problem I can prevent this from ever happening again.

Hi. Got this problem since last week and I'm really upset, since I've searched a lot and found no solution at all. I've resoldered white and red battery wires but no success... Could you help me with this tutorial about EPROM?
And do you still get these messages when charging if last boot was from Android? Or these characters are gone? Thanks for any kind of help!

Yeah, doing the thing with the battery wires did not work for me as well.
If you want to charge your tablet only once, you can use this trick I used:
Open up the tablet
Find the BIOS-chip
Remove the metal heat sink around the chip (it comes off easy)
Now unsolder pin 1. Heat the pin until the solder melts and then push the pin loose with a very small screwdriver
Now charge the tablet. The battery will probably get warm (not hot), and so might some of the chips. The heat will get less when the tablet has been charging for a couple of hours
Solder pin 1 back again
This is the location of the BIOS chip. It is the chip at the bottom of the picture below.

}
In the picture below the heat sink has been removed. Pin 1 is indicated with a grey dot on the bottom right corner of the BIOS chip.
Another solution, if your tablet does not charge at all when powered on. I did manage to get my tablet charging again with a custom USB cable. This is the video from 1KeNnY1KeNnY1 descibing the solution:
I bought these USB connectors from China on eBay (adafruit sells one too) and these resitors also from eBay. If you need the components fast I'm sure you can find them in a local electronics shop.
You will also need a very stable hand and a lot of patience to solder the USB connector. Make sure you get a few of them because you will probably ruin the first one.
Then:
Find a USB cable that charges with a decent charge. Make sure the wire is not too thick for the new USB connector.
Cut off the mico-usb connector and strip the wires
Solder the red wire to pin 1, and the black wire to pin 5
Solder the 2.2 kOhm resistor between pin 1 and pin 4
Do not connect the green and the white wire. If you do, Windows will think you connected a malfunctioning device when you use the custom cable.
Here's an image showing which colour goes where.
And this image shows you all the pin numbers:

Wow! Great tutorial, man. Thanks a lot!! Wish more people have your kind spirit and help others with less knowledge.
If I understood it right, first option gives me one full charge but I will have to open tablet again when battery is empty, and the bootloop error isn't gone. The second will let me charge it normally but only using the new modified cable and the anoying error is gone forever... Is that right?
I will try these methods asap this week and reply to you.
Many thanks!
Have a nice day.

You can still charge the tablet when it is off, and it won't charge when the tablet is on, right? I've searched through your posts but gave up after a couple of them. So I'm not really sure if your problem is exactly the same as mine. Could you copy-paste your initial problem report here in this thread?
I'm using Windows on my Teclast x98 so I used to hibernate my tablet automatically after 30 minutes of inactivity. When the tablet is off, it will start charging. And because the power off was triggered in Windows, the tablet will not boot automatically when the charging starts.
If you use Android, you're out of luck. You will have to boot into Windows and then shutdown the tablet from there to get it to charge. That's a major hassle. And if you forget it once and Android keeps running until the battery is too low, you will end up with the same problem you have now.
The custom cable is the best solution if your tablet does not charge when powered on. Other solutions will kill you tablet pretty fast. Doing too many hibernations will ruin the SSD. Desoldering the BIOS chip will also fail after 10 times or so. In both cases the tablet is ruined.

Thanks again for your help!!
No, I can't charge because when I plug it to energy, this bootloop starts and battery seems not to charge at all! When it enters in this bootloop state, pressing the power button does nothing. Pressing it for 10 seconds does nothing. Pressing power plus volume does nothing too. When I unpplug tablet from power, I get no response from it, just a black screen.
Before this happens, charging was working ok, I could charge it from both OS and didn't matter if it was on or completely shutted down. One day I was using it (don't remember in which system) and battery started to deplete itself from nowhere, so I plugged the original charger with original cable, as always. But they stopped working, battery discharged and then it was gone...
Ok, thanks for your patience and all information. I will try modding the cable, then I post here the results.

That sounds a lot like my problem.
I do not think the custom cable will get you out of this situation. My cable doesn't provide a lot of power (about 0.6A or 3W). When I use the tablet with the cable connected, the battery still drains slowly. So the cable does not provide enough power for the tablet to run. Booting the tablet uses even more power.
I think you will have to jump start your tablet and charge the battery once like I did. After that you can use the cable to prevent the tablet from losing all its power again. This works for me in Windows where I can put the tablet to sleep. During sleep it will charge slowly. I haven't tried Android yet. I will do some tests in the next couple of days.

I've done some tests today:
If the tablet boots it uses more power and the battery discharges, even with the custom USB cable connected
Charging under Android is very slow (approximately 10% / hour) if you are just browsing some websites. If you run a game or set the brightness of the screen higher I'm sure the battery will discharge
It is possible to power off the tablet from Android with the custom USB cable connected
The tablet needs more power then the USB cable supplies while booting. So you will not be able to revive your dead tablet with the USB cable alone. You will need to do the trick with desoldering pin 1 of the BIOS chip. I called that "jump start" in my previous post, but the comparison to jump starting a car is totally not obvious or correct.

Now I got it! Lol
What a pain to have bought this tablet. I thought it was a great choice, but one year later I'm dealing with BIOS and battery wires and modded USB cables.
Thanks for all the good info. You are great!

Friend,
Sorry for the long delay, but I had other problems with this tablet (the flex power cable broke) and for a long moment I gave up using it.
So here is the situation: I've fixed the charger and the other problems, and now I can turn it on but there are no OS anymore, it goes directly to a shell. I can access the UEFI settings and tried installing Windows via pen drive, but when it gets to the screen which allows me to choose the drive to install, it is empty. System is not recognizing eMMC anymore... Do you have any hint on this?
I think it's been a year or more since I use this device for the las time, and it will be great to get it back working.
Thanks for your time again! =)

hi, can I ask how did you solve your charging problem?. I have similar situation like yours, my tablet wouldn't hold the charge and it boot loops to shell prompt when connected to power source. I was not able to do the windows installation because once I remove from the power source, the tablet wouldn't bootup.

First you build a custom charging cable with the instructions on this thread. Then you connect a UEFI Windows installation (prepared by Rufus) via pen drive. Make sure you have a HUB to also connect mouse and keyboard. In all my trials so far I ended only being able to boot RemixOS and ChromeOS via live boot with pen drives, but they miss touch input and some drivers. I'm still trying to reinstall Android directly to eMMC, but I don't have much hope left that it will work... I guess this memory is gone with this error.

Droid 4 won't turn on, but recognized by computer?

I have a stock Droid 4 with a mugen power extended battery. Last night I got a vibration that felt like a Facebook notification on my Droid 4. I pulled it out of my pocket and tried to turn it on, but the screen remained black. I tried holding the power button to reset it, but there was no response. I tried plugging it into my wall charger that usually works with a usb cable that also usually works, but even after an hour, there were no signs of life. I tried plugging in the cable to my tablet, and it charges just fine. I've used other cables and chargers, still no luck.
I tried plugging in into my laptop with the cable I normally use for charging and my laptop picked up that a device was connected. I looked in My computer to see if I could access the phone internals, but I just saw a drive letter with motocast, and 2 other drive letters that told me to insert disks in to them. The motocast drive letter had what looked like motocast system files, but that was it. I had an SD card in my phone, but no drive letters that came up when I plugged the phone it let me access it. When I went to safely remove it, I saw in the device manager that it correctly identified that a Motorola XT894 had connected to it, and I safely removed. I've tried doing a soft reset, holding the power down+vol down button for 10 secs, but that does nothing. There are no lights at all, not even when I plug/unplug it from the charger.
I'm planning on going to a cell phone repair place today to have them remove and troubleshoot the battery ( I don't have plastic torx and I'm afraid of short circuiting the motherboard)
I feel that there is some hope for fixing the problem or at least data recovery since windows recognized my phone and I could at least get to the motocast folder on it. I do wonder why my phone is able to be recognized by my computer but still show no signs of life otherwise. Any ideas?
I love this phone, but it sucks with this happening around the holiday season.If it can't be fixed, I'd at least like to get my data off it. Please help!!
Is there any way to fix this? Would physically removing and reinstalling the battery work? Do I have any options for file recovery off my phones internal storage, especially since it seems windows recgnizes that my phone is connected?

UPDATE: Got it to power on and boot normally once. Enabled USB debugging when I had the chance.
Got back from the cell phone repair place this morning. He said the battery was definitely bad, drawing zero amps. He also said he was getting weird voltage spikes throughout the board, and I think he said something about the PCMI power management chip being bad and that the phone was done for. I told him that I could plug the phone into the the computer and it recognized it. He said my best bet might be getting a battery off eBay that would power my phone long enough to get everything off of there. I asked if it could also be USB cord related as I tend to have horrible luck with them. He said it could be and that the reason that I was able to have the phone recognized by USB but not charge is due to different pins communicating during USB connection. I'm including these details so you can gauge this guy's expertise. He did go from saying the phone was done to suggesting a new battery/USB cord, and I was able to power it on after using said cord.
I went and bought a new USB cord and plugged it into my inverter I had in my car. To my surprise after a few seconds, the phone was showing the charge screen with the battery at 70%. It still wouldn't boot up so I kept it plugged in for about 5-10 mins. Eventually it did boot up. I immediately went in and enabled usb debugging. All my data was there. For a brief bit the date and time was off, but even that corrected itself. I played a song from my music collection on my SD card to make sure that was OK. The song played, and shortly thereafter it looks like the phone powered back off as it had originally done. I hooked it up to my computer and my PC started installing new hardware, it said something about xt894(my phone) a couple of disk drives and a CD ROM drive, and something about adb. The furthest they got were as unknown devices, so I disconnected them and reconnected them a couple of times, eventually the install icon went away. It still recognizes the phone and even recognizes there is a storage device with the phone in the device manager menu, but it still says "please insert a disc into drive (letter)" The drive with just motocast is still there, and I think there was another CD ROM that was recognized, said to insert a disc same as the drives. I threw it on my wall charger for a few minutes, but it still wasn't powering on. I then realized that charging it could exacerbate the voltage spikes the guy was talking about, and I didn't want to risk it especially after seeing all my data there, so I unplugged it.
I do have the battery that the extended battery replaced. It had to be pretty much tied to a charger, but it did work if only for less than half an hour. So there is the option of using that to temporarily power the phone.
My new questions are:
Am I at risk of further board damage if I charge/power on the phone? What about charging the degraded but functioning battery?
Now that I know I have USB debugging enabled and my computer still recognizes my phone, how do I go about backing up the contents of my internal storage?
Could this all be effectively solved by just getting a new battery? What about what he was saying with the weird voltage spikes and PCMI chip?

Have you tried it without the extended battery. That could be the culprit of all this going on. If your original battery is bad get a new one and charge it. I had the same problem with a battery till I bought a new oem battery. After I charged my Battery I had to go to fastboot to get device to boot with a fastboot cable. Then while connected to that cable I backed up my contacts. Then while still connected to fastboot cable I flashed stock firmware and started all over again havnt had a problem since.

I'm waiting on an OEM battery to arrive. I was able to save everything off my SD card that was in the phone, so I am increasingly hopeful. Do you have to go into fastboot if your phone is stock? What is fastboot even?

AP fastboot mode is where where you flash stock while connected to rsd lite via usb or fastboot cable. It is part of bootloader. You hold down all three buttons to get to boot menu scroll down to ap fastboot then hit the vol. up button then connect to computer after you have rsd lite active. then flash stock firmware. If you get a battery that doesn't charge have them send you an other one that has happened to me a few times but not many. Remember when you scroll in boot menu you only have a few seconds to pic what you want to do or the device will try to boot.

The OEM battery I ordered finally came yesterday (no thanks to USPS). I tried multiple chargers and outlets with a good cable, and still nothing. I have another non-OEM battery arriving tomorrow, hopefully this one was just a D.O.A battery.

It was probully a dead battery. It sat for to long. If you had a fastboot cable cable you wouldn't need a battery to flash it in rsd lite or just to see if it would boot. There was this one time I had to order 3 battery's just to get one that worked. Sometimes they been sitting for to long being the device was made in 2012.

So your saying if I had a FastBoot cable I could boot my phone without a battery in the phone? Would it wipe my internal data/OD?
Update: I have had a BIN-TEK battery charging for several hours, still nothing. Good cord and charger too. The only other options I have is the extended battery that crapped out on me but powered on briefly, or the puffed out factory battery it replaced. Things are looking bleak

It is so you you can get to fastboot mode so you can flash. It is usable with a low battery or no battery at all. When you first connect it to computer it will automatically start booting. Here is a link for one: https://www.amazon.com/gp/aw/d/B00K...boot+cable&dpPl=1&dpID=41ep3FoxgHL&ref=plSrch
If it boots to your ROM when you first connect it then you have battery problem. If it does not boot to rom then you should leave it connected and flash stock firmware from fastboot mode witch you will need rsd lite to flash. If it boots after that then it us just a battery problem. If nothing happens then you probully need a new droid 4. Remember once you disconnect fastboot cable device will go off. So don't disconnect until you are done with everything being that you don't have a good battery.

I have a fastboot cable now. Haven't tried anything yet but I plan to today. I've looked around XDA for firmware If I need to flash stock firmware, I found several versions for the Droid 4 here:https://forum.xda-developers.com/droid-4/general/droid-4-xt894-firmware-mirrors-2015-t3004048 how do I know which firmware is correct?
Also, am I good to disconnect the fastboot cable from the PC as long as I am NOT in the process of flashing firmware?
I have ADB debugging enabled on my phone, and last I checked my computer recognized my phone, just couldn't access internal files on my phone. (Had "Please insert disk into drive x" message) Any options there?

You have the right index get the one says
4.1.2 - VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip just in case you need to flash. just connect cable and see if device boots if not flash the firmware with rsd lite. never umplug cable unless you want the device off because when cable is is pulled the device will go off.

I connected the fastboot cable without a battery in the phone. Held power button, computer detected it. Said it had found an XT894 and Motorola Network drivers or something like that. Said my installed hardware was ready to use. Noticed in device manager and network connections that Motorola USB networking driver #3 was installed. Under My computer, didn't see any new hard drives. I have RSD lite and the firmware you told me to get. RSD light shows my phone model, imei, software, ect and says that I am connected. But there has been no activity on my phone's screen. No Motorola logo, no menu's, nothing. I would feel more comfortable if I could pull my data off before I flash the phone as I have read horror stories of flashing gone wrong. Is there some way I can access my phone's memory since the computer recognizes it and backup my files before I flash?

When the device is off just connect the device to your machine and it will boot to your rom thats it. It will do it automatically. No need turn it on yourself. If it wont boot then something is wrong with the rom. If that happens and you were running a custom rom and not stock go to safe strap if you had it installed and use that to boot back into stock rom slot. Now you have two scenarios you can use. Do the first one I wrote first. If you Have safestrap installed then do that if it wont boot. Dont forget to have to have the drivers installed for the device on your windows machine. On windows based systems you have to have the drivers installed installed before using rsd lite. Just in case I forgot to mention that.

My ROM and phone is stock
Another update: I'm trying to use ADB to backup my phones files before I flash. Here is what happened:
Sorry for the lack of updates, been busy. Anyways, I got adb installed, plugged in my phone, did adb>devices, didn't show up.I got the newest version of Motorola device managermanager and had it update. Plugged in my phone again, computer said it found an XT894 and Motorola USB networking device, told me to restart my computer. Restarted, tried to see if adb detected it, nothing. It shows up in my device manager under networking devices, it even says the location is an XT894. But adb still doesn't see it.
The weird part is that RSD can see my phone too along with device manager. I'm planning on flashing to see if I can unbrick my phone, however I want to try and backup my files on there just in case the flash wipes my phone.
Is there a way I can have my computer recognize my phone as a drive instead of a networking device so I can get my files?
Is there any way to get my data off my phone before I flash?

Another update: I'm trying to use ADB to backup my phones files before I flash. Here is what happened:

The only thing I can think of at the moment is safestrap If you had it installed before you bricked the device then you could try booting to safestrap and then mount device in safestrap and copy and paste all your internel sd stuff you want to keep. If you did not have safestrap installed then make sure you have correct drivers for device installed and try the adb command again and see if it reads. I'v been in your situation thats why once a month I now back new stuff up. When I had the s3 I bricked during bootloader unlock. Took me three days with an image file to get it to boot. Then I reflashed the stock and didnt need the image file any more. That was long time ago. i learned to back my stuff up after that. I just thought I would mention that just so you could have a food for thought. Also data will be lost is another reason to back stuff up.
