I recently unlocked the bootloader via the instructions at HTCDEV.com
I then installed CWM and then rooted the mini.
Everything is fine except when I fully power off the phone then plug it into either the mains or a PC to charge the phone, a large battery icon appears briefly followed by a screenshot of CWM recovery which also flashes briefly then a constant green screen is displayed whilst charging.
Obviously something's not right...does anybody have any ideas how to bring back the charging battery screen whilst the device is fully powered off and charging?

Hello, thanks for your post.
I'm currently running twrp, it's a great program but it too behaves oddly...
When mini is powered off and plugged into charger...it switches on and boots to TWRP
It charges ok but the screen is unresponsive....I have to long press power to reset it.

My phone is rooted with stock rom. The only changes are listed below
Froze bloat that was safe
changed bootanimation to stock samsung
replaced some apps with inverted versions of themselves (ex. google +, stock messaging)
Here goes:
I was using navigation and I noticed that my phone was off after I had finished. Nothing worked at all, I could not boot into recovery or download. I connected the phone to a charger and red led flashes and an empty battery appears. The battery was full. I could reboot the phone while on the charger, but it would shut off as soon as it got to the homescreen. While off, If I pressed the home button, the green battery would appear as if it were charging. From here I could boot into recovery and download mode. The phone will only boot into these modes while connected to the charger. Here is where it went bad. I attempted to restore a backup while the phone was on the car charger and my car charger got pulled out in the middle of a restore. No charger meant that the phone shut off mid restore. Now, when I plug in the phone, the red led appears and the empty battery with a circle inside appears and then goes away. This repeats itself over and over and the phone buzzes when the empty battery reappears. I can still boot into download mode but not recovery. If I try to flash the stock samsung rom via odin, it says that it passes, however upon automatic reboot the samsung appears and nothing else. After the samsung appears the phone just continues to buzz every 5 seconds or so as if it is trying to do something. Could it be a bootloop? I have done a ton of searching here and now I am resorting to help! Your time is appreciated and beers on me if you can help me get my phone back to normal.
What Rom/kernel were you using before this happened? If custom, which one?
I have another thread a few posts down with the same topic. I am going to delete this one. I was stock rom and kernel. For some reason the phone will not recognize the battery. I tried a new one at verizon and the same thing. I can now boot into both recovery and download mode when connected to the charger , but the phone shuts off as soon as it boots and shows an empty battery with a circle in the middle. Sometimes it does not make it through the verizon boot animation and sometimes it makes it all the way to the homescreen and I can make a few selections before it turns off. After flashing the stock kernel and rom in odin I believe i am completely stock, however I do not want to chance sending the phone into Verizon. I believe that I saw a thread before this happened to me talking about having to calibrate the battery in some way and it had an item to flash in order to fix the problem. I can not find it now. Any ideas? Now that I can access recovery is there anything else that can be done? Why won't the phone recognize that it has a battery? As soon as I pull it off the charger it shuts off. When it is on the charger it appears to be charging and the green in the battery appears to be at about 80% but the level does not move up or down at all. Thank you for your help ahead of time.
Hi all I have encountered a strange problem this morning i Tried to boot to recovery from cm11 to restore my stock backup but the phone just turned off I tried to turn it back on but only a blinking red led would show so i Plugged it in to charge and off line charging said 96% of charge so i Just flashed stock ftf and still the same problem blinking red led so I held down power button and the phone booted so . Turned it off again and only met with blinking red led so i Plugged in charger let off line Charge screen popula. Then held power button and it booted again . Have no idea why it will only boot from off line charging . Can't boot to recovery or anything tried plugging in the charger so kernel boots then take out charger press volume- button when i See pink led but it just stays stuck at phantom bootsplash. Any ideas what's Wrong people seems to me when I normal boot the phone thinks the battery is dead i Have tried another battery but still the same any ideas.
Edit [Solved] fully charged phone then deleted batterystats.bin now everything seems ok.
Hello,
I flashed the latest LRX22C image on my nexus 5 today.Had flashed it clean,wiping data,cache and system etc except the Internal Storage.Then I flashed the SUPERSU 2.37 ZIP .Everything was fine for about 4 hours.Then suddenly when I pressed the power button to turn the screen off,it was not turning off and the "Switch off" mode was popping up instead .Then, when I got a call,it switched off.The phone won't turn on again.It starts,the Google Boot Splash appears and the bootanimation starts for like 2 seconds and it switches off.Same thing for bootloader mode.
Please Help me!
EDIT: Now its turning on by itself and switches off in 2 seconds!
Sounds like a bad power switch to me, but of course that is just my opinion. :good:
sounds like a mech issue.

I have the same problem on mine now... Basically my phone powered down around 45%. Battery. At the time i thought it was dead... But it wasnt. When i would plug into external power, either usb or through wireless charging it would power cycle continuously at the android splash screen.... (1 to 2 second intervals - even if i booted into fastboot) Interestingly it would never go to the battery charging mode. But automatically boot on charge... It did this for about 6 hours then i gave up and left it unplugged for a day. I plugged it back in and it started power cycling again, however this time on its third boot it came back to life . thats when i discovered i still had 40% battery... I dont know what exactly made it boot but it did. Oddly also on boot, it started optimising apps and finishing install again. I checked the md5 before I installed the update so no issue there. Since it powered up i have powered the phone off using the power button long push and let the phone power down. After doing this when i plug the phone in to usb charge it goes to the charge screen. No issue. That said, if i try to power up while tethered and charging it will not allow it. It just stays at the charge screen. As soon as i unplug the usb the power button allows the phone to power up and work... When booted up it charges as normal when plugged in. Im convinced there is an issue with the power management drivers or drivers for the button controls. My phone worked fine until the 5.0.1 update was installed. On my nexus 5. Anyone else or just us two? Ive had a hard time finding people posting on this issue.
I have a d850 that I bought used. It came with the stock updated image.
I rooted the phone, used an autorec app from the store to get TWRP on it, took a backup of the rooted image, (after much failed fiddling with other methods) and flashed the latest CM nightly for the D850 on it. After much fiddling, I finally found a GApps package that worked and flashed that as well to get CM working properly, then took another backup.
At this point I was pretty happy that I had everything working how I wanted. However, I paired my phone with my vehicle (bluetooth) and shortly afterwards the phone shut off.
In this state, the buttons on the phone produce no result. I tried a battery pull, plugging it in and some other shenanigans and nothing worked. Just when I was about to declare it bricked, I discovered something. If I pull the battery, and then plug the phone into power, the error screen comes up. At this point, I could reinsert the battery and the phone would switch to the powered off charging mode (green battery icon). From here, I can reboot the phone into recovery mode (via button pushes), but only if I remove the charge cable once the LG screen comes up. If I don't remove the charging cable, the LG screen comes up, then the phone switches back to powered off charging mode (green battery icon). From recovery (TWRP) I can boot the system back up normally and everything runs fine. I can reboot the phone without issue. However, if I power off the phone, I have to play the pull the battery, plug the cable game again.
I have no idea what portion of the phone (bootloader, recovery image, image, etc) controls what the buttons do when the phone is off. Anyone have any ideas on what I have hosed or how I can fix it?
UPDATE: I found a second method today. Inserting the battery while holding down the power button will also boot the phone successfully. Still clunky, but less clunky.
Hi guys, I can’t seem to find this anywhere on the forums.
I’ve inherited a Samsung J4 Core for a work mobile. It currently doesn’t turn on properly, but I know there is charge.
When I hold down the power button + Up & Down keys, this should boot into the Bootloader. My issue is that it boots up, but then quickly shuts down after a brief blue screen with what looks like a yellow triangle and the laying down Android robot.
Being as I can’t access the Bootloader, it doesn’t appear I can wipe/clear the rom properly. Does anyone know a work around as I obviously need this for a work mobile.
Thanks.

Download mode is Power + VOL down + VOL UP with USB cable plugged in.
The blue screen you are talking about is recovery mode. If it shuts off like you say the battery is completely flat.

It's bizarre as I've had the phone charging via the normal wall charger overnight and it still has the same results. Likewise with your above method with all the keys held down I'm still getting the same error. I'm now at a point where I haven't a clue what to do.

If you don't see the charging symbol it won't charge in this state.
The only method I know is to boot it to the download mode confirmation screen and leave it in that state while charging it overnight (may even take longer). There will be no charging notification.
Once it has at least 1% charge it should be possible to boot to Recovery mode with the USB cable attached and charge it properly.

Thanks, but even with that, it won't boot into the download mode either - just flashes and turns straight off., even with the USB cable plugged into my laptop.

Are you talking about download mode itself or the blue confirmation screen?

Everything. Using the method to get into the download mode itself, the phone turns on and for a brief moment a blue screen flashes with the yellow warning triangle and some, what I presume, error messages and the phone turns off.
