[Bricked] Flat battery, Won't charge, No recovery, No root

[blakie21737]

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.

It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.

Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated

What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??

 

[blakie21737]

The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it

I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !

 

[lecorbusier]

The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.

This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

I have the same issue.........!!!

I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........

Anyone??? Please???

With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Thank You

Advice to is find a way to Charge the battery then attempt other methods.
I think Kies may work if I have Charge

Cheers

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?

The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.

 

[number55]

Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing

 

[lecorbusier]

Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.

 

[number55]

I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V

From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?

Thanks for your info lecorbusier

With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.

Thanks for all your help.
I purchased a new battery and did a normal kies recovery and it's back from the dead... Thanks again
