Hello and how are you?
I recently flashed the latest doomkernel on my phone, installed a rom and all was working fine. However my batter dropped to 0% and now the phone is not booting up. I had it charged for 10 hours (twice) and when I press power button the red light flashes twice. I was not able to imitate a battery removal (power+vol up) so I removed the battery itself, waited and recharged. The phone is detected as a USB device by the pc, but I cannot flash anything since it turns off.
My carrier says this is a broken motherboard/mainboard
Has anyone experienced such issue? any help?
Mainboard is fine. Battery has to low voltage. I think the device cannot charge the battery, when it's turned off. You must charge the battery somewhere else.

Hi,
I did something stupid yesterday: removed the battery while booting. It was on the boot animation screen, after the Motorola logo went out.
Now I can't turn the phone on, the white charging LED does not light up when connected on the computer USB port or the wall/car charger.
Tried:
- Removed/reinserted battery
- Press power button with SIM removed
- Press power button with memory card
removed
- Press power button and X
- Press power button and UP
- Press power button without battery inserted, while on wall charger (?)
Android version: 2.1. Stock version, rooted, no overclocking.
There's no sign of life on the device. Tried leaving it for 2 hours without the battery to powercycle it and tried leaving it to "charge" in the wall charger overnight and still no signs of life. At one point the LED white light flashed for a fraction of a second when inserting the cable but it no longer does this I don't think.
Could this be a battery problem?
Just want to check with you guys before taking it to the authorized service, because it will take weeks to get back.
Thanks.
Alright, so I just checked and when I plug my phone into the wall charger, the LED comes on for a split second then disappears. Also, since I lost my original battery, this battery was bought online, not too sure if it is a generic battery though.
At this point, im leaning towards this being a battery issue. Am I correct?
use rsd lite and try to flash a new sbf image
Hi have you found solution of this problem ? Yesterday i did same thing as you while booting removed batery and now it is dead it wont charge battery and same as yours when pluging charger led flashes for a fraction of second ...
maybe u must reflashed the firmware
I have same problem with my Milestone now. Not possible to power ON my phone. Tried to plug it in PC but the system didn't detect it for RSD re-flash.
Anyone have another ideas? Thanks in advance.
My Xperia is rooted, has recovery and the bootloader is unlocked, I use the stock ROM.
It went smoothly (done it several months ago), but yesterday, the battery emptied so I put it on charge. Today I tried to turn it on, but it didn't work; whenever I press the power button, the LED blinks red. I tried fastboot and flashmode, but none of it works. My PC detects it as an unknown device when I try to turn it on. once
If that helps, it turns on once in a while with CWM.
Anyone can help?

EDIT: looks like I used a loose cable and the battery didn't charge at all. God, I feel so dumb.

hello;
I had the same problem , I searched on the web for solutions and found something like charging phone overnight , key combinations but nothing helped; my phone was completely dead ; but I did something and phone is now alive; I removed screw of the phone , opened panel; removed battery connector and connected phone to wall charger , by this time phone showed sony logo like on startup , then immediately connected battery connector and left phone to charge for several minutes ; it was showing only sony logo when was charging, after 15-20 minutes disconnected phone from charger , screen went off and after this i reconnected charger, it showed battery screen and started charging with battery and thunder logo; thats all, it was the only solution for me.

I'm so sorry for causing you the trouble of this....
Turned out that the cable I used is loose and it didn't charge or anything
I still didn't get my OTA in Croatia so I decided to try this. I came across an issue which wasn't present in official 4.1.2. and maybe someone had (and still has) it as well. I'm posting this here so that it's easier to find if anyone has this issue and wants to fix it.
I have installed 4.3 on my Xperia T with Locked Bootloader and everything worked fine. However, I have come across a issue and managed to solve it as well. Here's what happened and how I solved it, maybe it helps someone with same problem.
Today my battery drained to 0% and the phone shut down. Now when I plug it in to wall socket to charge, red LED goes on and it turns the phone on. Once Android boots I can see 0% in status bar and it starts shutting down again. Then it boots up again and loops like that. I remember that on 4.1.2. there would be a battery icon when it was completely empty and it wouldn't boot the system. Now it just loops. This didn't happen on official 4.1.2.
I have Googled for solutions and have tried this.
"1. Press and hold down the power key on the right side of the phone. If the battery status LED flashes red, try plugging the charger into the phone at the same time as you are pressing and holding in the power key.
When plugging the charger into the phone there is a risk that nothing happens – no red battery status LED as indication of charging, or nothing appearing on the screen.
If the charging doesn’t start, follow the instructions under To let the charger be plugged in for 24 hours.
2. If the charging starts, keep charging the phone until it’s fully charged. Indication of charging is that the battery status LED lights up in red, or that the SONY symbol appears on the screen and then the LED lights up."
Problem was that when I left it to charge (screen off, LED red) it would start booting again after a few minutes. When it started to boot, I would press volume up + power key to shut it down and keep charging. I had to do this many times (10 to 15) and it was very frustrating but it worked in the end. I decided to let it boot and voilà! it showed 1% battery and didn't start shutting down. Now it's charged to 2% and keeps on charging.
The lesson - don't EVER let your Xperia discharge below 1%, you'll have a world of problems.
I have the exact same problem, except that it doesn't even charge when my screen is off.
Great find! I used a separate way to get it to charge but I can assure you it gave me a world of pain! Thank you for sharing
What about the Xposed module DisableCriticalBatteryShutdown?
If or devices were no longer turning off again after booting when battery is 0%, the problem would be fixed, right?

I REALLY need help
Sometimes when i plug the charger into my Xperia z, it instantly shuts off and boots on
A week ago, i plugged it in, it restarted and i went to lunch.
When i came back, i couldnt turn the Phone on, i literally tried EVERYTGING (every buttom combination possible), the LED didnt turn on and the Phone didnt respond to anything.
Just completely dead.
I charged it for 3 h and because the LED didnt even turn on while charging, i thought the battery might be broken.
So i removed the backcover, unplugged the battery and plugged in the charger.
There was finally a sign of hope when the LED turnt red, but as soon as i plugged the battery in again (with the charging cable still in) the LED turnt off.
So i ordered a new battery, put it in and charged it for 2h, still the exact same issue.
If anyone has a clue of whats the issue or experienced it himself, please help me.
Phone specs:
Rooted, bootloader unlocked, custom dual recovery with twrp and philz recovery installed, stock rom with android 5.0.1, about 2.5 years old, perfectly functioning until this issue occured
Hello, lately I've been having some battery drainage issues with my Huawei Ascend P7.
For some reason it drains really quickly (sometimes even when the screen is turned off). Sometimes my battery jumps from 40%+ to 15% and when I plug in the charger, it jumps back to 30%+ really fast.
My phone is rooted, I'm using Doze and Greenify to save some of the battery when the screen is turned off and I also have "Screen power saving" option turned on.
I have taken some screenshots of the battery usage and one of my phone's specifications.
Does someone know what might be wrong with my phone or could there be something wrong with the battery all of a sudden?
Did you try to reinstall Android new?
Or at first a factory reset?

I flashed B852 package's recovery and boot. Then rebooted to recovery mode, wiped data and cache, then rebooted to install mode and installed B852 ROM (dload/UPDATE.APP).
The phone turns on fine, but the battery percentage just drops so quickly and once it even shut off when it was at 60%. When I tried to boot it back up it said it was outta battery.
And one time when my phone turned off and wouldn't turn back on, I plugged in the charger and it told me the phone still had 32% battery. I turned on the phone, unplugged the charger and it shut off in a minute or two. When I plugged the charger back in, it still told me I had 30%+ battery left.
I think the problems began when I flashed https://forum.xda-developers.com/as.../kernel-huawei-ascend-p6s-p7-k-tuned-t3355223 kernel. But I installed a clean B852 ROM and the problem still persists.
Thats really strange, but this kernel is not the problem.
I also have a P7-L10 B852 and using this kernel without any problem...
But right after installing this kernel I also had some strange problems...
Sometime my phone rebooted it self or if it was locked and I pressed the power button to wake it up, it just stayed black and it got really hot...
I don't know what py phone did at this moment because if you are looking at the battery info in settings, it says my phone just was turned off and even lost battery but it wasn't really off...
My solution was a clean install (erasing and flashing every single image and after that 3-button-method)
After that boot up your phone
Now shut it downs install the kernel again
Boot up
Shut downs
(Maybe flash original boot.img
Boot up
Shut down)
Install kernel again
Boot up
I'm using this kernel for more then a half year now and I don't face any problems anymore...
I think the battery itself was the problem. I removed the back cover, removed the battery and cleaned the connector pins with alcohol. When I turned the phone back on about 30 minutes later, under "Power saving" smart power plan option shows me the phone will last for 11 h 30 min at 83% (WiFi turned on), when it used to be like 2-4 hours at 90%. I'll keep monitoring for a while to see if the problem is truly gone.
Thanks for your help.
//edit1: Never mind, I tried playing with the CPU voltages and it froze, so I turned it off. Turned it back on and the problem was back. It jumped down from 80% to 14% and in a minute or two, the battery died. When I booted it into recovery, TWRP says I still have 34% left. So I rebooted into system, it showed me I did have 34% left, but it turned off. Going to try your advice now.
//edit2: Got it to work properly again. Hopefully I won't touch something that will mess it up again.
Maybe your battery itself is the problem but to proof that you will need a second P7 to change batteries of them...
But such extrem battery-problems I have never faced...
You could send it to Huawei support, maybe they will say you if your battery is damaged...
So you could buy a new one and change it
Have you tried calibrating your battery?
I don't think it's a calibration problem
But if you want you could try it...
Charge your phone to 100%
Now delete the batterystats.bin at /data/system
Reboot your phone
Use your phone normally and let it discharge right before it's shutting down it self (3% I think)
Now charge it again to 100%
While charging your phone you should not touch it or unplug the charger
Last night I went to sleep with the battery being at 90%+, woke up to my phone being dead (the alarm didn't go off).
Tried turning it on, it showed me I had 50%+ battery, but it turned off shortly after. I plugged the charger in, and it said I have 58%.
And yes, I have tried calibrating my battery. But I can try doing it again when I get back home from work tonight.
//edit: Battery calibration didn't help. I'll just have to wait until the new battery arrives. Or should I try locking the bootloader?
Why you want locking your bootloader?
Do you want to send it to the support
If you already bought a new battery, wait for it and put it in
Seems that the battery itself was the issue after all. After putting in the new battery, everything seems to be back to normal.
