FFF Bootloader - "Charging Low Battery - Please wait ..."

I've been using CM10 + Tablet UI for about two weeks - Super Fast and Location Services worked!
But now for about the last four days, I've not been able to charge beyond the "Charging Low Battery" screen.
I'm booting with FFF v1.4. The latest version of TWRP is also installed,
I cannot get to TWRP. Only displays FFF's "Charging, Low Battery" screen then goes black. No boot options are enabled regardless of how long the button is pressed. Green button comes on when it displays the low battery screen. Orange button never comes on.
I've tried all of the press and hold for 5,10,15, and 30 seconds as well as switching cables and usb chargers without any luck. I've waited for hours before checking to give it time to recharge, but the KF always returns to the "Charging Low Battery" screen.
I have an extended warranty, but not sure I can send it back to Amazon with FFF as the boot loader.
Any recommendations would be greatly appreciated.
THx

whoops you got a free thanks oh well at this point its obvious its modified so your warranty is void look here for info http://forum.xda-developers.com/showthread.php?t=1623244 but just hold down the power button till its off and plug it to stock wall charger for an hour and leave it if this does not work hold the power button down till its off and charge it via usb on your computer for a few hours...

Update: Got it working using the below steps
Assumptions:
a. KF - rooted
b. Boot Loader is already installed. I use FFF.
c. Recovery Loader is already installed. I use TWRP.
Steps:
1. Remove USB cable.
2. Press power button and hold for 30 sec.
3. Give KF a time-out: Let it sit doing nothing for 1 hour.
4. Press power button for 2 sec ~ gave me the "Battery Needs Charging" screen then goes black.
5. Press power button and hold for 30 sec.
6. Using a wall USB charger, attach cable to KF.
7. Should Boot with available options ~ select TWRP and continue charging until KF is 100%.
8. Enjoy.

[Q] Tab 3 7.0 SM-T210 reboot loop and no recovery

Hey guys, have a friends Galaxy tab 3 (7 inch, SM-T210) which simply won't power on.
Firstly, the device came to me because it was completely dead. He is using an Apple charger (5v 1A) which I believe isn't the right output.
After leaving it plugged into the Apple wall charger for more than a full day, it will power on the display and go into a boot loop (displays Samsung logo for about 10secs then reboots).
It never gets to a point where it shows the battery charging icon.
If I do anything to it (hold power button, power+home+volume up, power+home+volume down) while it is in this reboot loop, it simply dies again and needs the full (more than) a day charge again before powering on the display.
It won't go into recovery or download mode.
The longest I have left it charging thus far is about 2.5 days and still the same problems.
I have tried disconnecting the battery connector multiple times also (left disconnected for up to 5 minutes) - this just causes me to have to start the whole charging process again.
Any ideas? I'm currently leaving it plugged into my PC (rear powered USB port) in the hope that it will charge properly - or at least detect a connection to the PC when it enters the bootloop (maybe try ADB).

@fubofo
I know it is difficult.
A) Regards the Power Adapter.
Listen PC USB port should not be used as a charging station. You always run the chance to burn your PC!
In the other hand PC USB is designed to produce 5V but only 0.5 A.
We should always used the Power adapter that came as original accessory. I own a TAB3 10 wifi. Due to our 10" big screen our OEM adapter is 5V 2A. But in your case 5V 1A is fine. It just charges slower.
B) The most used solution is get in to Download Mode and Install Original Stock software. The other possible solution is to get into Recovery Mode and do a Wipe of Cache and Dalvik and if possible a Factory Reset.
I know you said: "It won't go into recovery or download mode." But there is no other way.
In my cases Tab3 10 Wifi I can not get the battery out. But since you are saying that you can, I will suggest you unplug the battery for a minute. Hoping that when you reconnect it it would not turn on by it self:
1) Turn your PC On.
2) Start Odin3.07 and prepare to install your Original Stock ROM.
3) Connect the USB Cable to PC but NOT to TAB. As you see we only want to be ready to install Stock Rom is everything goes OK.
4) Disconnect the Battery on Tab, (If not possible Press Power for 6-8seconds and release, If it reboots Press Power for 6-8seconds and release. Keep trying until you see it stop doing the loop with Samsung logo. We are trying to ensure is in OFF and that it does not reboot)
Note: Please understand that if you keep pressing [Power] or any other sequence of buttons longer that 8 seconds it just loop once and nothing happens. You need to release the [Power] button.
5) Wait a minute disconnected. (OFF)
6) Reconnect Battery. This is where I an hoping that the Tab will not Turn On by itself! I do not know I never disconnect my battery.
7) Be prepare to Hook the USB cable from PC. Now Press ONLY [Volume Down] and Hook USB cable at the same time. It is been said that when we press Just [Volume Down] from OFF the battery registers are reset and the Battery Icon comes up in your screen!! At least this behavior work in TAB3 10 Wifi. I am not sure in yours.
If you see I am just trying to get away from the "Loop on Reboot" situation. And I believe it your best chance to ensure is in charging state. If you like you can leave it charging for at least 1 hour with the battery logo. If the battery logo goes away and you want to check if it is still there DO NOT USE [Power] BUTTON. use the [Menu] instead. In fact in this mode you can unhook the PC USB cable and Plug your Power Adapter with I believe is twice as effective charging than the PC USB.
Now lets say that when you unplug and reconnect the battery, Tab3 instead Reboot (power on) Then what I will suggest you is to get help from some body else so that you have an extra pair of hands. The Idea is that if it power on by it self ,that you can be only in charge of Pressing Just [Volume Down] while hooking USB cable. The other person will be in charge on reconnecting the battery. I hope you get my point.
Lets continue
8) So now that you have a TAB charged you can ensure that PC is connected to USB cable and Odin is ready.
9) With the battery Icon on the screen, now you can Press [Power]+[Menu]+[Volume Down]. to get in to Download Mode. Note that In my case a TAB3 10 Wifi I do not need to press [Menu], Just Only [Power]+[Volume Down].
10) Follow any Tutorial in the use of Odin for your device. Just be sure NOT to mark "Re-Partition" unless you had received a packages that requires that. If you do not know that means it is NO repartition. Understand that re-partition without having a complete package will Brick your device. Most Odin packages have only the minimum packages so do not required re-partition. You been warned.
I hope this will help you.

@r2d23cpo thanks for this information, though there is a problem. As soon as I unplug it from the wall charger it stops the reboot loop and just does nothing.
Also....why do I need to connect it to PC via USB with Oden if we are not yet going to flash it? Would the wall charger works just as well after I connect the battery? (disconnect battery, wait 1 minute, reconnect battery, Hold Vol Down + connect charger)

I've noticed this with the Apple charger. But only with this particular model. I experienced none with the SM-T217. Other Samsung devices also charge fine with the same charger. The tab wouldn't show the battery icon at all, and the screen kept flashing. I left it plugged in for 1/2 hour and it moved up 1%. I don't believe it's the amp, 'cause the tab charged fine with a 1A Samsung or LG. You should switch to another charger first lest it damages the battery somehow.

This Tab doesn't ever get to the point of showing the charging icon. I currently have the device plugged into USB port of my server as it's powered on 24hrs. I'm happy to leave it in there for a few days to see if it charges better.
My hope is that it will at least get to the boot loop stage, and maybe show up as a connection on my server so I can fastboot it or something.

Not to belabor the point, but mine wouldn't charge at all at 500mA, which is what my regular cell charger outputs. So unless your server delivers more punch than standard USB ports on PCs, looks like you're in for a long and futile wait. Just my guess.

[Q] HELP! Nexus 7 (2013) died i can't power on

Good afternoon to all connoisseurs and Android entangled world.
I have a serious problem that I would like everyone.
I comment my case: has always given me good to change the ROM, rooting and general mess on Android devices, after use many terminals and taking advantage I'm in USA for work I decided to buy a Nexus 7 2nd edition. (The best purchase of my life). All went well for a few weeks, I install CM to the latest version, all automatic updates were done and went like a shot.
But after that I got to mess with it one day I was bored, enter the Alpha blackmart and install a program that updated the kernel, the program in question is called Franco.kernel.updater. In theory this would set me the latest kernel developer Franco and my Android device would be more configurable, faster and give me more battery life.
Well here comes the problem, since the release and upgrade the Kernel the tablet has not power on. I've tried everything I see on the forums: press power for 9999 seconds, button combinations, open the back cover and remove the battery, jump + kick + the joystick crescent ... (this last one is a joke), but NOTHING! can not get my tablet for signs of life.
This is my story, I hope someone can help me with my tablet, at least to me and then we turn life seeketh forum to restore all factory. Thank you very much in advance and congratulations on this forum that has been with us many years.

Hello,
I am sorry to hear that your Nexus 7 will no longer power on. You listed that you have tried button combinations, have you tried entering Bootloader by holding the Power button and the Volume down buttons? Typically if you have a bad flash you will still be able to enter Bootloader.
You can also try the following steps as well:
1. Charge the tablet from a wall outlet for one hour > Unplug your Nexus 7 > plug your Nexus 7 back in within 10 seconds > Hold the power button for 15 seconds.
2. Connect your Nexus device to a computer’s USB port while the computer is on. > After 10-15 minutes, disconnect the USB cable from your Nexus device and reconnect it within 10 seconds. > After 1 minute, check to see if a battery icon appears on the screen. > Press & hold the Power button for at least 15 seconds to see if your device turns on.
3. Press & hold the Volume down button. At the same time, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen. > Press the Volume down button until the screen shows the option to Power off. Press the Power button to select that option. > Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen. > Once the battery icon appears on the screen, allow your device to charge for at least 1 hour before turning it back on.
I hope one of the steps listed above helps you power on your Nexus 7. Please feel free to contact me for further assistance by emailing me at [email protected]. As a reference please include the case # N140933878 in the subject line. I am here to assist with all of your ASUS needs.

S 3 Start-Up Problem

Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.

Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.

Phone not turning on.

Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.

Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:
