Help needed, dead BA

Well, as always XDA developers is what you use when noone else helps you, my freaking BA is acting strange:
1. The phone doesnt turn on when the battery is in. Tried charging the battery 100% and switching it on but it just doesnt turn on.
2. Now when I place the BA in the cradle, the phone turns on but it just keeps on restarting.
Somebody please help me out.
The phone worked fine until when I tried to tape the body and the battery with cello tape, that is when it went dead, and now I have the two problems mentioned above.
Help me guys,
Thanks a ton all.

try a new battery.
and check the battery lock..

You might have messed up the pins connecting the battery to the device. Also, the little lock for the battery could be damaged as well. Finally, your backup battery could have died also. Hopefully this will give you some guidance towards the root of the problem. Chef has a disassembly guide in his tutorial.

well thanks guys for those responses. My updates are:
1. Since the battery was over 3 years old, I have ordered a new battery (yeah i know i should've checked with another battery first but damn noone else i know uses this phone). So till my new battery arrives I just got to wait.
2. Regarding ezthunder's replies... well I checked the battery connectors on the phone, they seem to look alright to me (physically), how do i test them to check if they're alright, pls help.
Also, regarding the backup battery, damn i would now need to search the net to find a new one.
The battery locking clip seems to be fine and is locks the battery in place, if this is damaged, I'd be freaking damned to try and get this one fixed.
So guys, any DIY suggestions to get these things fixed would be welcome as I dont wanna brick my BA, freaking just put in a new LCD digitizer.

Let us know what happens when the new battery arrives and we'll go from there.

well my battery arrived yesterday, i put it in and tried to switch it on but alas nothing. Charged the battery full and put it in but no start up.
Just the same old problem, phone keeps restarting when in the cradle but nothing when out.
Help me guys............

Well still no response from the forum, however, I have a few updates and hope this could make it easier for someone to figure out the problem:
A strange thing happened yesterday -
1. when I disconnected the flex cable of the buttons and the keypad on the front panel from the main board and put the entire thing on the charging cradle. IT WORKED. I mean it didnt do the restarting problem, it worked perfect. However when I took it out of the cradle, it wont power on. While it was on on the cradle, i checked the internal battery and it showed 100% charge, which means that the internal battery is good.
2. Now back when I connected the flex cable to the connector on the board and power it on - nothing happens and when put in the cradle - the same restarting issue right after the statup screen.
So based on the above - what are your conclusions, is there a problem with the flex cable connector but then in that case it should start when taken out of the cradle.
And yes, its a new battery that I just got. So guess its not a problem with the battery...
Help me guys. I really want to get back my BA... it was such a pleasure to see it working in the cradle with mentioned in point 1 above.
PS. I left it on the charge for the whole night yesterday but no change when taken out of the cradle - just desperate to try anything to get it to work.

Judging from this, it seems that there is a problem with the motherboard itself. I could be wrong, but that's what it looks like to me. You can probably get a new BA from Market Place. I have seen a few members selling them lately.

*bump* still waiting for some good soul to help me out with the prob... i really dont wanna lose this phone...blue angels are real beautiful babies to have around...

[Q] Won't boot or charge at all

I just got my moto360 today and being the eager idiot that I am I booted up and connected to it. I put my watch on the cradle to charge for the first update and it was losing battery, so I turned the watch off and waited for a couple hours. Now I can't turn the watch on at all and it seems completely dead, it isn't responding to the two qi chargers I've tried that have both worked before. Did this happen to anybody else when they first got their watch?

I looked in the thread and I didn't see anything that pertained to what happened to me. My watch was about at 30% on arrival but quickly died, but now it won't boot and the two moto 360 chargers I've tried don't light up when it's docked.

LG G3 Dead

Having a bit of a nightmare day! I have a 855 G3 and have had it around 18 months. Its rooted, and has been running ok.
Today, I was using the phone, then had to do something. When I went back to it, it was off and wont come back on.
I have tried lots of things - removing battery and plugging in, leaving battery out for a while, trying to plug in without battery, holding down various buttons in various sequences, pluging into the PC - and nothing at all.
One time I took the battery off and plugged it in, I did get a display that indicated there was no battery installed. I then put the battery one and a charging screen came up for a few moments, then it went dead again.
Anything else I can try, or has it got to go off for repair?
I saw this http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 but I don't want to do that if I can still get a repair under warranty.
Its bought from Amazon Germany and I have to send it back to them, they are happy to repair it. Is it going to be a problem that its been rooted?
One last question. I need to buy a cheap, but reasonable phone to keep me going in the meantime. Any suggestions? Saw a Moto G 2nd gen.

same thing happened with me as well Mine is US Cellular G3
the diff is
I was trying to boot in recovery ( TWRP , mine was rooted ) but it looked as if TWRP was gone to i pulled battery and restarted and used the native AUTOREC app to reinstall TWRP once done when i tried to boot in recovery
my phone never woke up
and its still in same state
( you were lucky to see charging screen for a few seconds , but i instead just see that empty battery screen when i plug it in without battery , that too goes away once i plug the battery inside
guyz plz help

I think I have tried everything now. Ordered a new battery to try, which should arrive in the next few hours but I am not holding my breath. So, looks like its got to go back to Germany and hopefully they will repair or replace it!

Too bad , and yes believe me new battery might not solve it , but then keep your fingers crossed.
all the best

New battery just arrived. So, I put it in and it started to boot! The LG logo came up, I got excited and then....bang turned off! Very strange.

Sort of the same happened to me today. Let's hope is battery.
My G3 shut down suddenly although battery was at apologize 75%, blue screen and splash logo and flickering and then black screen.
After some time I managed to boot up and then 2-3 minutes later...off again. Repeating procedure, booting up and then immediately booting twrp. I thought something is wrong with my setup: fulmics 3.7 and xceed kernel latest nightly; managed to restore a backup (stock rooted MM) and everything was fine.
Phone boot up normally, apps beginning to update, made a few calls...and then...boom...shut down with the same flickering to blue screen. I hope is battery issue related. My phone is from August of 2014 and a bit abused since December (MM update).

Same here, no recovery, no download mode, nothing... I've tried shorting the pins and using boardiag (tests are all PASS except for SDRAM which I've been told it needs a power source to boot the device a.k.a battery ) so i highly suspect it's a battery thing

Sent mine back today. Got a Moto G to keep me going in the meantime.

Mine is now on the way back to me after a quick turnaround. Not sure what they have done to repair as can't log on to the repair tracking website for some reason, but will find out next week when it arrives.

Still waiting, but I now have the repair report. The phone they are sending back has a different serial number, so I presume they are sending a new/refurb phone?

I've sent my phone(with the same symptoms) last week in service under warranty although it was rooted and from service center I have a tracking information that it was repaired (probably mobo replaced). So, I will know for sure in a couple of days

Try connecting it to PC without battery, you notatras that it decteta pc , if so you are lucky , you step tutorial, the files are only for d855

Mi 5s Sudden Death?

Hello everybody,
so yesterday my two year old Mi 5s died completely after crashing 3 times in about 30 Minutes.
After the first crash I noticed that the battery status had suddenly dropped from ~60% to 33%.
Now, after 3 crashes, the Phone seems to be completely dead. No Bootscreen, no status LED when charging.
Also, the phone doesn't even get slightly warmer when plugged into a charger.
It's literally just a brick at this point.
Because of the suspicious battery drop after the first crash, I suspect that the battery just died.
Fortunately I ordered a replacement already, about 1.5 weeks ago.
My question is this:
Would you suggest waiting for the new battery (which should arrive in 2-3 weeks) and hoping everything works with a new battery?
Or would you rather buy a new phone?
Even if you are not an expert, I would still appreciate your opinion.
In case anyone wonders, I was using LOS15 with latest(-ish) firmware and magisk, though I suppose none of that matters for the issue at hand.
UPDATE: After removing the battery; plugging in charger; attatching battery and repeated plugging in and out I now have a blinking red LED.
Victory? Not sure .. I still can't boot but at least something is working?

this thread sounds similar to your situation... https://forum.xda-developers.com/mi-5s/how-to/blinking-red-led-death-t3743795
worth a shot before your new battery arrives. and since you already ordered your battery its best to wait for it and install on your phone, while putting your sim in a backup phone. if it still doesn't work then buying a new phone would be the best option.

Thank you for your reply! I tried the methods described in the thread you linked and updated the OP.

I had a similar problem 2 days ago. I changed the battery, now it works again.

Same thing in my case - new battery helped.

Thanks a lot! I revived my old Nexus 5 (what a great phone!!!) and will stick with that until the battery replacement arrives.

New battery fixed the phone, it's working normally again (and lasts much longer ?).
