Hi, I am having the same issue, after dwnloading and installing Lollipop 5.0.1 the tablet is not charging anymore. Tried different cables and is not charging anymore. Do you know how to fix it? I am thinking to download the 5.0.1 image and install it.

Sorry to hear you have the same issue. I send my tablet back for replacement!

I would flash all the images again. More than likey either boot.img or recovery is corrupted. They both control charging.

Hi all, i'm having the same problem... have you been able to fix it?
Unfortunately it's impossible to me to send it to RMA so I need a miracle :crying:

[Q] Screen won't go off !!

Hi, I have a Galaxy S2 (I9100) that's on a stock rom GB 2.3.4
The kernel is KH3.
Phone works fine, but I cannot update to higher android version because KIES says my device cannot be updated with KIES.
After searching these forums I managed to root my phone (flash a rooted kernel with ODIN) and installed a custom rom.
I tried MIUI rom (JB) and also ParanoidAndroid (JB) and both have the same problem.
The screen shuts off after the 30 sec setting, but then after 1 sec it's ON again.
After 30 sec its shuts off, and after 1 sec it's ON again
If I flash a stock rom back (KH3) the everything is fine again.
Also flashed a MIUI ICS rom, which has the same problem!!
Anyone heard of this problem before, or knows what to do??
1. Did I do something wrong?
2. Is there a way to go to ICS stock rom (KIES or another way)?
Please help....
1. Flash a different kernel
2. Or go to Sammobile and download stock firmware, flash it with Odin.

Did you do full wipe before flashing a custom rom?

I did
- factory reset
- wipe cache
- wipe dalvik
Then install rom
if custom rom - screen on after 1 sec.
if stock rom - screen normal
************************** UPDATE **************************
Flashed a stock kernel from SAMMOBILE (Latest ICS 4.04 for Netherlands) with ODIN
Same problem !!! Screen turns off after time out, 1 sec then turns on again..
I found that with this firmware an app called "Screen Off And Lock" was installed.
Does that mean that Samsung knows the problem occurs in ICS (and higher).
I checked the option with the delay especially for devices tjat turn screen on again after turn off,
but still the same problem stays.
******** ANOTHER UPDATE *********
Just found out....
Everything works OKAY if I connect the phone to my PC.
It's charging then offcourse, and the USB is connected then.
That must be a clue to the solution, but I haven't found it yet.
Maybe someone else has an idea now (I really hope so)

Maybe your usb port is f*cked like mine, Does it happen only when you fully charged the phone ? becuz my device recognize it as charging(when not having a charger connected), ---> so connecting/disconnecting every time . . My screen goes on/off cuz it connects/disconnects the charger (while no charger connected.) If this is your problem u can try cleaning usb port or check this post http://forum.xda-developers.com/showpost.php?p=30290884&postcount=3619

Thanx anyway.

[Q] Continuous reboot on Xperia logo

Hello,
My Xperia Mini started to reboot continuously and the only way to stop it is to remove battery. I think this have something common with battery, because after this happened battery charges very slow (about 5% per hour) but when I plug the charge cable it works fine.
I tryed to flash another rom and kernel but this doesn't helped.
Before that happened it was another issue, when I was turning on the phone battery sometimes was showing 100% (after restart it was fine).
I have unlocked bootloader and root.
When this reboots started I was staying under the sun, can it be caused by overheat? Does anybody know how to solve this problem?
Thanks.
This continuous reboot is called bootloop. You may have installed an incompatible mod before or well, something just happened. This should not have anything in common with battery. Reflash your choice of rom then wipe dalvik cache. If still doesn't work, wipe data.

I already flashed another rom with kernel (inlcusive stock) and wiped dalvik cache, also made a hard reset and formatted the flash card but still no luck . I think is caused by bad battery becase when is plugged it works fine, it's like battery doesn't charge anymore (it doesn't get warm) and always shows 100%. I will try to replace it and say the result.

Battery shows negative value

Hello guys,
I've recently bought a Redmi Note 3 Pro (3GB RAM) and the first time I booted it up it showed that it has -2% battery life. Since this seemed strange I tried to charge for several hours, but no change was noticed. I then tried with a battery calibration app, tried factory reset and restarting the phone, but nothing helped. I am also not able to go in recovery mode for hard reset as it states that there is no charge ...
The strange thing is that the phone is working for now and I am using for a second day with still the same bug. This leads me to believe that the problem is most likely caused by incorrect battery stats saved on the phone, but I am not sure. I am also not willing to root it or flash it since it is brand new and I might lost the warranty.
Can you guys suggested me a solution for this or the problem is not easily recoverable?
Thank you for the time and answers!
I have the exact same problem, tried resetting everything, I suspect it is a hardware problem.

Try updating, I had this issue with custom ROM's something certain boot images have this bug.
I flashed a new boot image and bug was gone but had no wifi reverted back to latest global stock via MiFlash.
If you have TWRP try the ROM here https://xiaomi.eu/community/threads/6-7-7-11.32639/ it seems ok.
Did anyone find a fix for this issue. I have the same problem. Battery percentage shows negative 2% and I can't get into recovery because of that. When I press Power and Volume + It shows the battery icon in red and won't let me into recovery. I have the Redmi Note 3 Pro Snapdragon version.
I tried flashing a couple of ROMs via MiFlash with no positive results.
Maybe a bit late, but the "camera fix" in this Thread fixed my "-2%"-Battery

Just flash with TWRP.

What rom are you using?
EkiFox said:
The camera fix works only with Santosh's CM13, not with other CM/AOSP roms
the new kernel Radon V1.8 by Umang96 does not fix the battery problem
Click to expand...
Click to collapse
The Radon V1.8 Kernel actually causes this bug on MIUI based roms, so don't flash the kernel.
Radon Version 1.9 will resolve the battery bug on MIUI and other roms.
Talking about cm/aosp I tried almost all combination kernel/rom.
No success except for this particular cm with camera patch.
Same problem with battery, showing -2% but phone is working... Plz provide solution asap
If u run MIUI, just download FASTBOOT ROM, restart phone to FASTBOOT MODE and flash ROM using this tool. But if u run custom ROM just flash custom kernel (like RADON).

Fixed the -2% Bug on latest CM13-Snapshot for me!
You Sir are awesome
flashed the latest global firmwareware(not developer one) solved my issue, also now my phone updates OTA.
Use only the official rom. custom that sellers flash usually is a junk just with additional options for menu's language!

Flash the latest miui ROM in edl mode using miflash. That is the answer.
No
No that is not the answer it's a hardware issue short circuit in motherboard

Hmm, well flashing an official ROM in edl mode has fixed this problem for many people, including myself. So it would seem that in most cases at least it IS a software issue that can be fixed by flashing.
My phone came from Banggood and a vendor ROM that wouldn't even support my FP reader, Goodix, and which booted up with the -2% battery bug out of the box. Flashing the official global stable ROM, 8.0.2.0 at that time, fixed all of the issues.
Hmmm may be sir but that doesn't seem to fix mine although mine is from xiaomi only and the problem came after using 6 month suddenly without any reason one morning
Ok guys there are 2 solutions to this problem one is drain your battery and don't charge it for 2 3 days drain it like he'll coz after switch off still some juice is left you have to drain completely and other rapid method is open your redmi note 3 and disconnect battery cable and reconnect it... The problem is not software its hardware where battery reading stuck at minimal which is - 2 ... Thinking minus two hours coz at zero still some battery left for edl and fastboot mode time and alarm... Fixed my redmi note 3 hope it will help you.. Coz tried all method format... 10 times flash all roms through fastboot mode Coz updater mode won't work coz of low battery reading... Enjoy guys
I am having a same issue with redmi note 3 SD version. Tried everything Global BETA ROM, STABLE ROMs but didnt solved my issue. Showing -2% bettery in every ROM which i have flashed.

Problem when connecting to battery charger (23s)

Hello.
After updating to 23s, I'm having a annoying problem when connecting the phone (X820) to battery charger.
If I connect it in standby, display lights up to notify that charger has been connected, but after that it doesn't turn off automatically after some seconds, how it should normally do.
The display remains on forever, unless I click the power button.
Anyone has the same problem?
There should be a setting somewhere to let you change the screen on while charging. Try setting -> lock screen or battery. I am not on stock rom cannot help you more.
It's under development settings, remain on when charging or do not turn off display when charging.
For some unknown reason was enabled by the update i guess
Thanks to all for answers.
I'm sorry, but it isn't the problem, that setting was already disabled, I've tried in any case to enable/disable it, but the problem is still present.

Oh strange!
Unfortunately I don't have another USB-C cable to try it, with the original cable display remains "On" after plugging in the charger, but how the cable can affect that behavior?
Problem still present.
Can I see some log for trying to understand what is the problem?
Nobody can help me? Nobody has this problem?
Tried full wipe and reflash stock ROM many times, tried 26s, tried other EUI based ROMs, tried hard reset via QFIL, tried changing the charger cable, but nothing, the problem persists...
It doesn't happens in LineageOS or other LineageOS based ROMs, so it is surely a software issue, but I can't understand what is the damn problem...
Did you tried indain 19s firmware?

Do you have the same problem? 19s it's an Indian ROM, I can downgrade to 20s and try, but I'm on Crisbalgreece EUI ROM, that is so good, and I wish I can solve this problem with updated ROM...

Mi pad wont charge red light.

Hi guys,
I was using Miui in mi pad 1 but it was really laggy IN VIDEOS and many apps including netflix wont even load in 4.4.4.
I moved to lineage 14.1 shield and apart from camera all were good.
i thought of upgrading to oreo and in middle i broke the device.
I went back to stock rom but i choose latest Chinese build 9.2.4.0 and use mi flash tool to boot it up. I was able to boot fine.
Again i went to custom rom dotos 2.5 and could see on locksreen showing phone charging slowly.
I kept for 3 hours and still same. I thought issue with the rom. WIPE EVERYTHING and again install lineage 15.1. It was able to boot fine but still no charging.
I kept my pad for hours to charge but still red light blinking, not booting up.
I removed the backpanel to remove battery (connector) and insert it again but still same.
I am not sure what to do now. If it will boot up i can go back to stock but it is not even booting to fastboot.
PLEASE HELP.
THANKS
