Hi,
I want to update my ROM from a standard WM5 to WM5SE rev 5.0. Following instructions, I downgraded with the button ROM to let me CID unlock my G3 Jammin. The butotn ROM installed, but when it reset it would not boot and both the red and blue lights would flash together, the screen would flash on, and then it would shut off.
This pattern is repeated every couple of second and doesn't stop until I pull the USB cable out, after which it repeats once more then switches off. I can't turn the phone back on with the power button. From here I can get back into the locked cycle by powering on with the USB cable plugged in (back into reset cycle), or into windows with the mains power cable (see below).
I think this means that the problem is related to my USB cable being plugged in. When I put the mains power cable in, the PDA will boot into windows. Related to this is what I think may be the main culprit. In setting, Windows says the battery is on 0%!!! Even the mains power cable doesn't seem to ever charge it, so I think it must be a software problem related to the ROM. Inceidentally, I recall that I had to softreset near the end of Button ROM's install, perhaps this is part of the problem...
Now I can reinsert the USB cable only during the Windows boot process, which as mentioned has to be initiated with the mains power cord, ie. I swap over half way through. If I change from mains power to USB after Windows has fully booted then the phone resets and the above reseting cycle occurs again.
Once Windows is fully booted with the USB cable in everything is stable and Activesync detects the phone. The problem is that when I try to reinstall a stable ROM, the update software throws the following error: Error [220] mains battery power. So the software I believe is reading that the battery is less than 50% (ie. probabaly thinks there is 0 charge left) and I can't reinstall a new ROM!!
The other thing to note is that I can get into bootloader mode with the mains power cable, but as soon as I try to switch over to the USB cable, the phone resets and it again gets locked into the perpetual reset cycle.
Please help me!! Any ideas are appreciated.
Gavin.
Hi,
Found this: http://forum.xda-developers.com/showpost.php?p=1216580&postcount=23
Seems like a similar problem. He solved it by replacing the battery. Is it possbile to destroy a battery while flashing a ROM?

Wow 40 views, and not a single idea?
Well I think I'm going to invest in a cradle, so that I can have both mains power and a usb connection, hopefully I'll be able to reflash with this. Anyone have expereince with this method? What is a good cradle?
A coworker decided to replace the non-user-replaceable battery in his Droid 4 (it's actually pretty simple to do). The surgery seemed to go fine, but immediately afterwards the phone is basically acting as if it doesn't have a battery in it:
'M' logo comes up when plugged in
Holding VOL UP/DN+PWR allows access to the boot menu, but none of those options allow it to boot past the 'M' logo
No response from power button when not plugged in
Immediately powers off when power cable disconnected
I read that a factory data cable might help him, so we ordered one of those. This cable allows the phone to boot now (furthering the suspicion that it doesn't think there's a battery in it - the factory cable is supposed to allow this, and there's just an exclamation point for the battery status), but isn't much help otherwise as data can't be transferred from it. Point being, it's not a software brick - it boots fine with the factory cable.
Could this just be a bad battery or something? Has anybody here ever seen this behavior?
Thanks!

Hi,
It might be a loose connection. Did you make sure that the screws were fastened properly? Also check the battery contacts on the phone and the battery, clean it if necessary.
Are you sure that you didn't bend the battery ribbon cable? It is pretty sensitive, can be damaged by bending.
I'm pretty sure that the phone is OK, it's a battery connection problem.

This is screaming bad battery to me - either it was duff in the first place, or has been damaged during installation. Having said that, I've swapped lots of batteries multiple times, and have never damaged one during removal or installation, so if they were careful I suspect it was bad in the first place.

Hi there HTC fans.,
I'm having a problem with my HTC Desire 500, and I really need your help because I can't really figure out the cause of it. Basically, my phone just doesn't want to charge anymore.
The problem first started at work. I had to download some photos from my phone into the PC from work, and I did that using a data cable from one of my colleagues. At first, the phone didn't connect to the PC, but after I unplugged it and connect it back, it worked and I was able to copy the photos I needed. However, a notification message appeared on my HTC's screen. The message was "Your phone is in USB Host Mode" or something like that. I'm having this Desire 500 for about 6 months and this message never appeared before when I copied things from or into my phone. I ignored that message and I unplugged the data cable and carried on my work.
When I went home, I tried to charge my phone but that didn't worked. I tried the both ways available: directly with AC charger and connected to my PC. But nothing happened; no charging signal, no red LED on. Nothing. I tried to go into fastboot, and even made a factory reset, but still the phone didn't charge.
However, I noticed today that somehow (by a miracle) the phone started charging when I used the same data cable that I downloaded those photos at work.
In conclusion, my HTC Desire 500 can't charge unless I use that specific data cable (from one of my colleagues).
So my question is: why is this happening and how I can solve my problem?
Thanks in advance for all of your answers and sorry for my bad english.
Maybe USB port is damaged? Check if there isn't anything suspicious inside your phone USB or the cable plug

Thanks for your answer, lgiK.
1) regarding the phone's USB - I don't think it's a problem with the phone's USB jack, because the phone actually charged with the data cable from the colleague that I've told you about. He also has a microUSB cable (like all the other Android devices).
2) regarding the cable plug - I don't think the problem is with the cable plug, because I've tried to charge the phone at home with 3 different AC chargers (all from other Android based devices), but it still won't charge.
I really don't think that it's a hardware problem, I suspect that it's more a software bug (or something similar). I think that mainly because that message appeared for the first time ("Your phone is in USB Host Mode"), although I'm having this phone for nearly 6 months.
Did anyone had the same problem like I do?

Last night my phone completely ran out of battery and has turned off. I put it to charge on a normal AC charger, and I noticed this morning that his battery was full.
So... yes, I suppose the phone charges when it's turned off.

Then try factory reset. Maybe there is something wrong in the software of the phone. Switching modes USB is a software issue. In the USB host mode, the phone is not charging.

I've already did that, but no change occured. I also tried going into fastboot (that also didn't helped). So i'm running out of options. The phone is still in guarantee, so I'm thinking I will just take the phone to them.

Guys,
I had the same "in USB host mode, can not charge" problem when the power is on, after 3 months of use of my new HTC One. It may be related to the charger but I am not 100% sure. It was very annoying and I had to turn the phone off before plugging in the power cable to charge. It happened when I was in Taiwan, so, I called the HTC help line there and they gave me a solution.
The guy on the other end asked me to go to Power setting and click off the "Fast Boot" and "Power Saver Mode" options first. ( I am not sure if these steps are necessary, but, anyway I did as he requested.) Then, power off the phone by pushing down "Power Off" for 2-3 seconds to allow restarting in Safe Mode. Once the phone restarts in Safe Mode, some of the Apps may not work but the phone can be charged normally. After restarting my phone in it's normal mode, the "USB Host Mode, Can't Charge phone" problem was gone. I can charge your phone normally and also click back on the "Power Saver Mode" and "Fast Boot" options in Power Setting, without problems. I hope this will also work for your phone.

Check the usb connector. And then just send in for repair.
My Droid Turbo power buttons seems to no longer make contact (I don't hear any 'click'). I was concerned about these from the start (I've owned it since right around it came out in October last year). At the least, I was able to wake my phone up by calling it and setting the volume rocker to wake the phone. I leave the country in about 12 hours so this is a pretty frustrating discovery.
Anyway, can anyone confirm whether the Droid Turbo turns on after charging after it was turned off?
I've read in another forum that a Qi wireless charger will turn the phone on to charge it- does any know if this is how it works? If the phone is off, the Qi charger will turn it on and then perform a charging? What if it is drained completely? My buddy at work has an Energizer Qi charger, and his phone (Nexus something) did not turn on from being off when I placed it on the charger.
I have USB debugging enabled- would I be able to utilize adb to turn my phone on when it is off?
Thank you in advance, I'd try everything I'm asking except if none of them work my phones kaput.
'adb reboot' might turn it on if you have USB debugging enabled, but I would wait for someone to confirm this (I can't try it right now). I don't know how this would work but one Google result says it does.
For waking up the screen, there is Moto Display which responds to accelerometer motion and Moto Actions, Approach... which senses your hand motion.
I would just not turn it off, turn on airplane mode to conserve battery when not in use, maybe bring another phone as a backup.

Still no workaround?
I just ran into this problem. Power button is completely broken (no click, or any resistance given when pushed in), and phone died last night. The first time this happened, i plugged it in to charge and it booted right up after getting an initial charge of about 5%, but now nothing. The display shows that I'm at %100 charge, but cannot figure out how to actually power on without using the power button. Anyone had any luck with this yet?
Assuming your phone is powered off , Hold volume down key and connect charger cable. You will get into bootloader screen. Disconnect charger cable and connect phone to PC and use the following fastboot command to boot your device without actually using power button for once.

Thanks for this. I'm in the same boat. I'm at the bootloader. What do I need to be able to send the command to the phone? Is this what ADB is for?
You're welcome
First of all, you will need to have motorola usb drivers installed in your pc, download and install from motorola
Then, you need fastboot.exe in your p and,execute from windows command line. Have a look at Minimal ADB and Fastboot thread for information on how-to and downloads.
The rest as i posted, when the phone is off, keep volume down key pressed, connect charger, you will be in bootloader mode. This mode will let your phone and pc communicate only via fastboot protocol. So you can use the " fastboot reboot " command to start your device without a working power button.
dude you are the man. this thread and method saved me of having to buy a new phone cause i thought my phone was gonna be a paper weight. thanks for all the info on the fastboot protocol
i love you, thanks man.

Qi Charger Works
"I've read in another forum that a Qi wireless charger will turn the phone on to charge it- does any know if this is how it works? If the phone is off, the Qi charger will turn it on and then perform a charging? What if it is drained completely? My buddy at work has an Energizer Qi charger, and his phone (Nexus something) did not turn on from being off when I placed it on the charger."
The Qi Wireless Charger works whether your phone is charged or not.. I went to the Verizon store and asked to see the charger demo'd... I placed my powered off, Fully Charged, Broken -power- button- Droid Turbo on the charger and it Came to life.
I immediately configured the phone with an alternate power button app to control the screen on/off. FYI None of the apps I found will actually power the phone on from off, but will control the screen once it is powered.
I actually tried everything in this forum short of the disassembly of the phone but that was next... the program download.. Reboot Fast Boot; I couldn't get it to download correctly. after about 3 hours I quit... drove to the store and the rest is history. So Glad Not to have Lost everything!..
When I try this in the command prompt it says The device is not ready. I have all the Motorola's drivers downloaded so why isn't it working?
Thanks so much for sharing the minimal adb fastboot info, my son had issues with his droid turbo power button. I ear raped him for not taking care of his phone. I felt bad but we were both amazed at my new computer skills. im totally a computer retard and powering his phone back up with that program felt great ....THANK YOU SO MUCH!!!!
You are welcome and i would like to thank to that unknown hero for gifting me one month adfree xda

Thanks for the confirmation that this works. Not comfortable taking my Droid Turbo apart and would prefer to avoid that if at all possible. I have multiple QI chargers at home and work so hopefully that sustains until I get a new phone in 6 months. Will re-explore disassembly as an option when I find a good video for the Droid Turbo.
The Fastboot method worked perfectly! I'll be able to limp along until I get my upgrade. Thanks!
Like yours, my Verizon Droid Turbo has a broken power switch. I accidentally allowed the battery to drain completely and could not get it powered on. However, I placed it on my QI charger I use for my Samsung Galaxy S7 Edge and it powered right up. Very happy that worked for me.

Well, using fastboot you can boot to TWRP.

adb reboot recovery
Function: Reboot your phone into recovery mode.
A lot of functions like flashing ROMs to your phone require you to boot into recovery mode. Normally, this requires you to hold down a particular set of buttons on your phone for a certain length of time, which is obnoxious. This command allows you to boot directly into recovery mode without performing the complex finger dance of your people.

From TWRP you can install the OS, you can drag files from your PC to install on your phone, you can RESTORE the backup I KNOW you made before doing any of this.

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?

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
OK

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?

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.
