[Q] Droid 3 bricked

My droid 3 will not boot, if I plug it in to my computer, it will not turn on and it will show no screen, it all happened after I restored my phone on a low battery. It is missing certain files like the bootloader so i can't restore the rom on the phone. What should I do?

Maybe it needs to charge. Plug it into a wall socket.

Well I need to get the phone back up and running and the bootloader as well as the charging program is missing. I have a brand new battery for it. It is fully charged.

I got the phone up and running

The problem was when I originally tried to flash it... it failed due to dead battery... WORST MISTAKE EVER... so I purchased a fastboot cable and tried to get the phone up and running but it was mounting the device in windows as OMAP4430 so I tried again last month and I got it back up and running with the latest version of android... the one that came with the device.

I AM SO ANGRY AT THIS PHONE.. IT WILL NOT EVEN BOOT IN TO ANDROID!

I'm having a similar issue with trying to fix a friend's phone that only displays the "Dual Core" logo when plugged into the computer. The computer itself doesn't appear to register that the phone is connected so doesn't show up in device manager that I can see. Plugging into a wall outlet doesn't light the device screen up, only the computer (Win7 box). I believe he dunked the bootloader, and it's bricked, but I'm trying to fix it anyway. Anyone reading this, I would appreciate any useful pointers or suggestions. Thanks all.

battery maybe dead, if software is corrupt/soft bricked, phone will not charge battery
get a Motorola Factory Cable Adaptor by Team Black Hat or Battery Desktop Charger for Motorola Droid 3 XT862

That occurred to me as well, I'm going to first see if the local Verizon store can charge it (or even replace it) for free. My friend actually did manage to score a power cable, but I'm not convinced yet that that is what I need (since I'm getting nowhere with it). I'd like to eliminate the battery as an issue if possible first before spending any money.

Verizon will not replace battery for free, if phone is more than 1 year old
The software that charges the battery is very easily corrupted, can be reflashed with firmware, but need a charged battery.
The TBH factory cable adaptor will power the phone direct from usb port, no battery is even needed, then firmware can be flashed and charging will work again.

I've actually gotten a battery in the past for an obsolete phone, but out of packaging and possibly used. My friend acquired a power cable (not sure from where) which just lights the screen as described above (with or without battery installed), but turns off as soon as I unplug it, so I have my suspicions about the usability of his cable. I struck out with the local Verizon store, so will just order the wall charger and charge the battery next. Crossing fingers... Thanks for supplying that link tho, that's the one I will use.

Follow-up: It took 3 weeks to receive that battery charger from Singapore of all places, but it worked. I didn't charge it up all the way, maybe just to 50%. The phone with battery immediately was able to boot into fastboot. Using rsdlite and motohelper installed, I had the phone back to fully functional within 15 minutes.

One thing you should check.
Is the battery bulged on one or both sides?
If you lay on a table, does it spin like a top?
If so battery should be replaced.

No, the battery was/is fine (in fact, fully charged afterwards it lasted 2 days on standby). I think my friend probably was just trying to flash a new ROM and didn't notice he had such a low charge. Still not sure why the cable he bought didn't provide the necessary charge to recover, but that's what you get sometimes with aftermarket equipment I guess. Still, it's good to know that is a possible solution for someone else down the road.

[Q] TF701T is not charging via dock

Hello!
I have a strange issue with my new tablet. Dock is not charging my tablet even the tablet's battery is under 70%. For example, right now I have 57% of the tablet's battery (Not charging) ant 98% of the battery of the dock. The power led on the tablet is orange, but on the battery section of the settings it's said it's not charging.
If I plug a charger on, the tablet's battery starts charging (orange led and screen indication), the dock's battery is green.
The version of the firmware is V10.26.1.28.
Is it a software of a hardware issue? Do I need to bring it to a service?
Thank you.

Have you tried undocking re-docking?
sounds software related. I didn`t notice that on mine waiting for it to come back from it`s 5th trip to asus (who knows they might replace it...).
If a full reboot and undock redock does not resolve the issue i would suggest sending it away. you could also try factory reset of course.
btw i know you say it`s new (but how new) did you have this tab before that version of firmware?? if so was it happening then?

Sure I have tried undocking re-docking many times, but nothing changed. I've also tried to reboot and factory reset with no use.
I did a firmware update to V10.26.1.28 at the first boot of the tablet, so I don't know if the issue was present at the previous version of the firmware. If I should check it, I don't know how to roll back.

Quite a few docks with a 2013 build date had that charging problem. Check the manufacturing date of the dock on it's box. If it is 11/2013 or earlier, I would send it back for replacement. People did get 2014 docks. Don't settle for less.

Battery Problem pls URGENT HELP!!!

I have tab s 8.4 lte model. Got it new. I was getting 3-4 hours of screen timing which was ****,
I did the back cover removal procedure and disconnected and reconnected the battery connector to see if it fixes the problem.
I then started tne device and draimed the battery to 0%. I then connected charger and charged the tab for over 5 hours. Just now i saw that it showed 100% charged.
I removed the charger and switched the tab on and it says 1% battery...WTFFFFF???
I connected charger again and now it says 9% left.
WHAT IS HAPPENING?? CAN SOMEONE PLS HELP ME?

Its probably not reading the battery correctly. Have you tried recalibrating and drain and chargeing it for like a couple times?

Im guessing your rooted. Well go into the play store and search for battery recalibrate. Pick one and install. Then follow what it siads to do and it should clear your battery stats. Now about the charging, i had a phone that didnt go above 50percent charge. So what I did is let it drain completely till it cannot turn on with the power button. Now just use a different charger or somesort and let it charge fully and dont turn it on till its at 100 percent. Then try and turn it on without the charger and see if it reads correctly.

Now completely drain and charge it for about 2 times. If that doesn't work then it might be something loose with the battery.

Had same problem custom kernel fixed my problem i have tab s10.5 lte battery drained from 100 to 0 in 40min
---------- Post added at 04:16 PM ---------- Previous post was at 04:09 PM ----------
If u dont want to try custom kernel install advanced battery calibrator from play store and try with that it seemed to help with tab s aswell

Yeah resetting the fuel gauge could help. Try sky high kernel

Hi there. I also face exactly the same problem as you. Today I open the back cover and disconnect and connect the battery connector. But my Tab S become worst. Does your tab become better?

Then your best chance is to rewert it to stock and hope that they wont check knox count in warranty repairs.

I'm guessing you have a micro sd inserted.
Check your battery stats. See if "media server" or "indexservice" is in a high percentage. Turn it off. Tha saps the battery more faster than Sylvester says "suffering sukatash!"
Heavy usage results into 4 hours batt average
If all else fails looks like you have a faulty battery

HI... How things athithi going on? Can't you replace by your self the battery? Someone knows where to buy an OEM battery?

My 8.4 battery is doing really weird things.
It'll be at say 34% and then plummet to 5% and shutdown.
So i plug it in, and the battery meter icon will pop up saying theres 25% battery available!.
I turn on the tablet and use it normally again. Very odd/

i had this issue once , the battery went crazy , auto reboot after a few minutes, then i went to customer service and they said that this issue was common :v They fixed the battery connector and it was normal again :v

Download battery monitor, this is probably the most comprehensive battery app available. It will tell you if your battery is actually charging and not just the phone detecting the charger being plugged in. It measures mah, if this doesn't change then the battery isn't charging

Droid Turbo turns off automatically

Hi guys,
My phone turns off automatically. It actually has happened 4 -5 times in 3 days. Let me explain; Once my phone was just on my table and I picked up but it was off and nothing was happening. I just plugged in my wall charger (Turbo Power), it turned on and the charging showed 53℅ so it came back to life. Today, my phone was on charge and it was almost 70℅ andI had to remove the charger but as soon as I removed it, screen turned off and then I had to put the wall charger again to make it alive.
What could be the issue? I am confused.
Thanks!

Attached is an image of my battery stats for reference. Thanks!

82% wifi battery drain? Do you still have this problem if you keep wifi off? I would perform a factory reset if I were you.

Yes, the issue is still there when I keep my WiFi off. Also, i noticed that my phone used to get charge from 5℅ to around 40℅ within 15 or 20 minutes. I did put my phone on charge few hours ago but in one hour it was only 53℅.
I use Turbo Power wall charger and I purchased this phone 2 weeks ago. I'm not sure if doing factory reset would work or not but first I want to make sure there is nothing else wrong with this.
Any thoughts?

If a factory reset doesn't fix it, my only other guess is that there is something wrong with the battery. If you purchased it new, it's very easy to get a warranty replacement through Motorola if you live in the USA, but I'm not sure how it would work outside of it.

I just posted in the "Weird Battery" thread. But you need to do a Battery Re-calibration by holding the power button to turn the phone and KEEP holding button until the phone re-boots itself. Ignore the "Power Off" dialog. Then plug in the stock turbo charger overnight. I had this problem a lot while using a wireless charger.

Thanks for the response and I will definitely try this. However, there is something I noticed: Today I plugged in my Turbo Charger and the phone started charging from 4%. After 45 minutes, it was 22%. I think that means it wasn't turbo charging and as soon as I plugged out the cable from my phone, it turned off and again I had to plug the cable in and it turned on and started charging. I then turned on my phone and the battery was at 22% (charging). After next 30 minutes it was at around 70% and then I tried to pull out the charging cable to see if it turns off again but it didn't.
I am not sure if it's right but I feel like when it doesn't get a turbo charge, it gets turned off when I remove the charging cable from it. But when it actually gets turbo charge, it doesn't turn off and act normally.
This is really confusing, isn't it?

No one?

The most likely problem is that your battery is failing due to age.
Although it appears to maintain a usable voltage, reflected in the battery % displayed, it can no longer provide the current needed to run the phone under high-load conditions. In those cases the voltage drops momentarily below the 0% level, triggering an immediate shutdown.
Try taking the back cover off the phone and seeing if the battery is significantly swollen or bloated. If so, it's time for a replacement. There are good video guides on YouTube detailing the process.
Your device is two years old, and all batteries wear out with enough charge/discharge cycles. If the phone is exposed to high temperatures (such as during turbo charging), the batteries will wear out faster.

Are you sure it can be a problem of battery? I purchased this phone in start of February and it's new. Also, if it's a battery problem then why does it happen just sometimes? Why not every time i plug in the charger? Also, my battery after full charge give me a handsome backup of 1 and a half day easily even after 81% use of a WiFi.

A weak battery is one possibility, but if you're getting a day and a half of usage from a full battery, then it's probably a different problem.
My next guess would be a bad charging cable or damaged USB port. Or possibly a poorly written app that's running in the background and causing memory problems somehow.
What Android version or ROM is on your phone, what background apps are running, and do you have any root programs or system modifications?

Thanks for the response. My Android version is 6.0.1 and in background I am not sure where to look at but the usual stuff I use are Facebook, Watsapp, MyCafe game (I have already tried uninstalling it to see if it's causing the problem). My device is not rooted and there are no modification. I am using this phone as I got it new. Thanks!

For few days it was working fine. Now, I was facing the same issue again so I tried to do a factory reset. Now when I tried to boot it up for the first time, I was setting up the Google Account, I didn't remember my password so I first changed it using my PC and then tried to sign in on my phone but now it's always saying "please sign in using one of the owners accounts for this device". I tried to google it but all of it ended up giving me a solution that I have to wait 72 hours because there has been some Google Security or something? I don't understand. Please help!

sounds to me like the battery is dying/dead. i would certainly open up an inquiry to motorola to see if they can get you a new battery. doesn't hurt to ask.

I had to encrypt the device and it's back to life now. But still, the issue is still there. The phone still shuts down automatically as soon as I take off the charger. It's weird that when I don't face this problem, I get day and a half battery backup which is totally normal to me. Do you think it still can be a bad battery problem?

Hi Sh-Obaid!
Although this is a pretty old post, but I have just faced the same problem with my droid turbo as you were facing exactly a year ago. I am pretty sure that you must have ditched the droid turbo by now, but still I am curious to know if you finally found out the actual problem or some solution. Please share your experience as it can help me to fix my paperweight (almost dyeing turbo).
It keeps turning off during boot-up or android running mode within a few minutes after the charger is removed. But, it can stay 'on' for several hours in recovery mode (due to which I doubt that battery is dyeing) and also shows Good Battery status in the boot-loader mode. I have done factory reset and even re-installation of the stock rom but neither worked for me.
Any input from you would be highly appreciated - Thanks!

Battery 100% On, 80% Off

phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted

l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery

Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped

Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.

I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)

I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?

So... any solutions?
