Hi guys,
I've had me evo3d from the first day it came out here, august 6th. Never had any problems at all. Until now. Srry about the novel... I've highlighted the most important parts for your convenience.
About 2 weeks ago, i dropped my phone from about 60cm, but with no apparent damage. Later that night, my battery went completely empty (not unexpected, it was a long day). Plugged it into the charger when i got home, led flashed to indicate a completely empty battery then stayed on to indicate charging, no problem. Then it stopped charging after a little while and didn't resume.
I took the phone apart so see if maybe some wire had come loose from falling. None had, but after putting it together again, it did charge again for a moment (also showed flashing leds again), and then it stopped again.
A friend of mine suggested it might be that battery's contacts, so he scratched them with a screwdriver. This actually seemed to help and everything was fine for about a week and a half.
Now trouble has started again. Taking the battery out and blowing on the contacts (NES cartridge style) worked at first, giving me about 10 minutes until it died again. But it seems to be getting worse, and by now it will only turn on or even just charge sporadically. Always flashing the led, indicating the battery is completely empty.
additional info:
It's not the rom that's faulty, as i hoped at first (re-installed an old rom after trying some ICS-goodness the day before all this started), because it also crashed in Recovery at least once. And i've already installed a diffrent rom without any success.
When it crashes, it doesn't just die instantly. Instead, it freezes for about 1/3 of a second. When it crashed in Recovery, during this freeze the text got a weird yellowish background-color and a different font color as well.. but the parts of the screen without text retained their original looks.
What else could i try to fix this? I don't know anyone with a shooter, but i've heard pyramids battery works as well, is this true? Can i try one of those to see if it's just the battery that's tripping?
Let me know if you need any more info.
Thanks a lot for your help in advance!
I didnt had the same problem, but I had something similiar.
Try this:
1. Unplug from charger
2. Get battery out
3. Wait a bit, and put battery in
4. Press Volume Down + Power button
or
4. (better solution) Press Power + Volume Up + Volume Down + Camera button
5. Phone will start
6. Just plug it in
It's known as "Chargning bug" when you flash some roms
It's the charging bug due to flashing clockwork recovery-- search the forum there are many similar threads and solutions
Hi,
Thanks for your responses. But that's not what's happening. In fact, i have an old clockworkmod that's never been a problem at all and i never updated it.
I tried your solution, though, but it only allowed my phone about 15 minutes of charging before it died again.
If it charges, it charges just fine while the phone is off.

Hey Folks,
I have a Samsung Galaxy SII (SGH-i777) that I used a couple of years ago. It was my first Android phone and I loved it very much (until corporate made me an iSheep).
The phone was retired to a shoe box for the last 1+ years and I recently dug it up so I could get it set up for my little bro who somehow recently fell on his phone with it in his pocket and shattered the screen (don't ask... I don't get it either).
Anyways long story short -- the phone sat idle for a long time, when I pulled it out it wouldn't boot up at all. Assumed that the battery had discharged so I plugged it in to see if it would start up. The battery logo would intermittently flash on the screen and show a drained battery logo but even letting the phone sit for a day did not provide me any results.
Fast forward 3-6 months. Today I replaced the charging board thinking that there was some issue with the USB connector on the phone that was preventing it from getting power. Once that was done I discovered that I was able to get the phone to boot into Odin mode. Great! No boot, no recovery, but download mode seemed to be better than nothing.
I have tried, in vain, to flash stock firmware to this phone via Odin, and even though all indicators point to it being successful, once I finish the Samsung logo comes up on the screen, goes off and that's it. I can see the 4 LEDs on the buttons at the bottom of the phone flash every 5 seconds as well as a faint flicker on the screen staggered between the LED flashes.
Looking for any further suggestions as to what I may be able to try. I have searched various sources on XDA and other sources but I haven't quite found anything that matches my exact symptoms.
Furthermore, I can't be sure what Kernel/ROM I was last running on this phone. Maybe Siyah kernel, maybe CM 10,1 with Flux kernel. Idk.
Any input is appreciated!
Seems I should mention this other detail --
With the battery in, I cannot get into download mode -- it just states 'Low Battery!! Can't Download!!" This is presumably due to the fact that the battery is completely discharged -- maybe incapable of holding a charge but perhaps this is indicative of a more serious hardware failure.
I'd guess the battery is completely shot.
I bought a replacement battery from here: http://www.ebay.com/itm/111014533334?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
No problems with it.

Very likely --
Since you got me to shift focus here, a quick search is telling me that it won't boot without a battery due to a feedback circuit. This would explain the ability to go into download mode but the lack of boot / flashing LEDs I guess.
Can someone confirm?
If the phone was working normally when it was put away, I would expect it to be working normally when it was pulled it back out. Your story is a little confusing, but did you ever try booting the phone with a fully charged battery? In the circumstances you describe, that would be the first logical trouble shooting step. And if you haven't tried that, then it is still the next logical trouble shooting step. Also, you can't assume that the original battery that you left in the phone is still able to hold a charge. It still may be good, but you can't assume that for testing purposes. Incidentally, the battery should have been pulled from the phone before it was put away.
I do not get any indication that the original battery is actually charging. Charging icon just flashes on the screen briefly in between LED and screen flashes (again, presumably due to the battery being completely dead/incapable of holding a charge since I left it in the phone this entire time).
I guess I'll go ahead and buy another battery and see what happens.
It is my understanding then that this phone will not boot on the charger without battery due to a feedback circuit. Correct?

Even if the battery is good, but fully discharged, it may not charge in the phone. You would have to have an external charger. Phones are not consistent, and many phones probably would charge a fully discharged battery, but I have seen a number of people report that a fully discharged battery would cause the exact same behavior as you report. If it were mine, I wouldn't throw the battery away yet.
If you know anyone with an I777, you could borrow their fully charged battery for a few minutes just to see if your phone will boot.
You are correct that the phone will not boot on the charger when the battery is out, although you should be able to successfully flash firmware through Odin with the battery out, and the computer supplying the power, but still, as far as I know, it will not boot after the flash without a working battery.
The battery was indeed at fault. Ordered a new one on Amazon, popped it in and voila -- we're up and running.
Thanks for the input guys! Much appreciated!
Hey all,
so a few months ago my SGS2 went off. It was an interesting behave of it, it just started to turn off sometimes, without any reason, without any popups (eg. battery low) or anything. I was really curious about this problem but I didnt have a single idea of what happened to it. Like a week later, it didnt turn on at all. I disassembled it, and found out that my secondary microphones cable broke. I thought that was the problem, so I ordered a new module (which includes vibrating motor, secondary microphone, ear-piece, and the jack).. I waited 3weeks, the first one arrived broken. I waited another month, and today the second one arrived in one piece. I put it inside the device to see if it works but its not. NOW the problem is, like it was before I ordered this module, when I try to turn the phone on, it doesnt do anything at all.(with the broken secondary mic cable it did, it went till the samsung logo and then bam, blackout) IF I put it up on charger, it says the battery is FULL, and from then, I push the power button and it starts to turn on, but goes until the Samsung logo, or sometimes it did boot, but thats rare, and then again BAM, blackout. Now I was like wtf? So i tried to reach recovery, I did a full hard reset to the full stock SGS2 ROM, tried other kernels, recoveries, ROM's, but nothing helped me. NOW If i enter DOWNLOAD mode without the charger, it says "Low battery! Cant download." and this happens right after i plugged the charger out, and it told me that the battery is full (what a liar), but when i plug the charger in, I can reach DOWNLOAD mode, and Recovery mode too, but they do blackouts after a few minutes too...
Any ideas?
Would be happy if anyone could help me out...
thanks :good:

oh and if it matters, its GT-I9100, 2 years old.
if you can get your hands on a different battery, i would recommned you to test it with that too.
as your device is 2 years old and i am assuming you havent changed the battery yet, there are strong chances of battery life getting over.

thanks for your response!
well today i am about to test a new battery, i hope thats what the problem is... an extra thing, and yes im stupid because of this but i left my battery in the phone for the 2 months while it was off... a friend told me that it can cause the batterys death, is that possible?
If u want to leave your phone switched off then it's better to charge it and then remove the battery from the phone. So there is a possibility that your battery is Screwed because of that time when you kept it in the phone itself.

Alright, I've got a hum-dinger here. I've been running CM12 for some time now, I started noticing much more frequent blue screens due to modem crashes so I wiped and reinstalled the ROM. Now I'm getting a really strange problem where so long as the phone is plugged in to something (charger, or computer) I can use the phone completely normally. The moment I unplug I get 1 of 2 scenarios:
1: the screen immediately goes blank (no power down sequence, no blue screen) and I'm kicked back to LG splash screen which then proceeds to go to the power off state. Attempting to power on again gets as far as the CM12 boot animation and then screen goes blank again. I've tried powering on several times from the stage only to get part way through the boot animation and then kicked back to the black screen.
2: Screen does not immediately go blank, I can swim around the home screens scroll to an app, even start an app - but about 10 seconds into the app the screen suddenly goes blank and I'm back at scenario 1.
The only way to get the phone past the ROM boot animation is to plug it back into something....but then I can't unplug lest I end up back at scenario 1.
The shutdown sequence almost looks like I tanked the battery, but going into the recovery (TWRP) I can see that I actually have a good 98% left.
Thinking CM12 had some issues, I tried another Lollipop ROM (blisspop) and I got the exact same behavior. Thinking Lollipop was still half-baked for this LG I reverted back to a KitKat ROM (CM11) and I got....the exact same behavior.
I tried wiping all the data, system, cache, dalvik, partitions and reinstalling completely from scratch -- but I get the exact same problem. The only thing I haven't tried yet is LGNPST back to 100% stock, but I'm struggling to see what difference that would make as I'm wiping out everything except the recovery between tries.
Anybody have any ideas, thoughts, comments? I'm grasping at straws here.....
You could always try to load the stock rom back on the phone to see if that does anything. Another thing you can try is to power off the phone, plug it up to the charger and see if it charges overnight, however I have a sneaking suspicion that the battery is toast.
Kilogrm, I've left it charging overnight and and am able to carry it around all day without issue doing the occasional glance at the time, but if I try to do anything of significance I will end up at a black screen again, so I'm rather inclined to believe it isn't the battery. I do have a replacement battery that I bought a while back that I never got around to installing....so I could try that.
I'm guessing that if I'm going to install a stock ROM I might as well just LGNPST back to stock....thoughts?
Ok well I used LGNPST to go back to JellyBean Stock, and I got the exact same behavior. I'm thinking it might be a hardware problem, but not sure what.
Well, it was definitely a hardware problem. I opened up the phone and took a look at the rigid-flex board that LG used to connect to the micro-usb jack and I noticed that one of the footprints was missing a component. I quick look around showed that a small(looked like 0402 size) diode had somehow sheared off at the solder joint and was rolling around in the case. I soldered it back on, replaced the battery with the new one I had gotten and closed the phone up. Everything works like a charm again. Now I just have to go back through the root/freeg/rom process again because I flashed all the way back to at&t ROM.
Remove the back cover, remove tiny screws on bottom and pop the cover off. There are another two tiny screws holding the battery connector on the pcb. Unscrew the tiny screws and unplug the battery, then plug in to power. Then unplug, plug battery in and plug power in. Let it charge. This added 8 extra hours on my battery from 15 hours to 24 hours. It appears to be going up too if u drain it to 0 dead and charge to 100 and unplug. Do it over and over again forever and the battery will slowly repair the damage.
Hi there,
Over the years i've done several smart phone repairs, screen replacements, batteries, new cases etc. All of them without any problems. A Few days ago a friend asked me to replace the case and screen of a Huawei P20 lite. Everything went fairly smooth, however after i finished replacing the parts and put the phone back together it does not turn on completely, only the charge light turns red and the phone is vibrating non stop while on charger.
Note: The phone has not been used +- 4 months before repair. When i remove the charger the phone dies again. Sometimes when powering up, the boot animation starts (max 2 sec) but then the screen goes black again (vibrating continues and charging led stays on). The battery was a real pain to get out, so it took some light bending to get it out. Not sure the battery is causing the issue though.
What i've tried:
- Charge the phone with different chargers/cables for 1 hour +
- Charge from low power charger for 4 hours.
- Leave the phone 2 days and try again
- Took it apart again and put it back together, exact same issue.
- Try to start the phone without battery/screen/camera's and other devices that are not mandatory, same issue persists.
- try to get in recovery etc.. no success.
Could anyone help me how to find the culprit of this issue, im really lost.. Any tips are much appreciated.
Thanks in advance!
check batery by multimeter first and if posible use other for test.
take tooth brush and clean all connectors in phone also.
Did u test screen before asembly it ? it was works ?
Hello I have the same problem and I fixed
Dear,
This is solved by changing the sense of the motherboard cable, incredible but True
A couple of days ago I replaced the battery on my Poco F1, because the phone is 2.5 years old and AccuBattery reckoned it was at 71% health. There were no issues with the phone, only that the battery life wasn’t as good as it once was (it was still running from 100% - 0% battery charge).
I bought the battery from AliExpress (this one to be precise) and the process of switching it out was easy and faultless, as far as I could tell.
The reassembled phone booted up fine and the new battery was at ~ 50% capacity. On the AliExpress listing it said to run the battery flat, which is what I did and it lasted quite a few hours - all good.
I then recharged the phone to full, as stated in the instructions. Regretfully, I interrupted the first recharge a couple of times by unplugging the phone for a few minutes each time. I'm telling you this for full disclosure - I'm unsure if this is likely to have caused the problem that I am now facing.
The fully recharged phone lasted a few hours and then shut itself down, whilst on ~ 70% battery I believe. This was the first time I realised there was a problem. The phone would not turn back on - holding down the power button and/or any combination of volume buttons did absolutely nothing. However, plugging the phone in caused the battery charging screen to appear instantly and subsequently, holding the power button whilst still plugged in would turn the phone on as normal. The phone would then boot up and battery percentage would be at ~70%, as it was when it shutdown (once booted, volume keys work fine). The phone would appear to charge as normal, but whenever I unplugged the phone, it would eventually shutdown on a high percentage after anything from a few seconds up to around an hour.
I thought I must have gotten a dodgy battery, so I took it out and put the original one back in. Now the old battery has all of the same symptoms as the new one – it won’t turn on unless plugged in and randomly shuts down after a period of time. If I manually turn the phone off when unplugged, it won’t turn back on unless it is plugged in. Also, a reboot just shuts it down.
I happened to have a spare charging port board, so I put that in to see if I’d fried something on there, but that hasn’t helped.
I’m tempted to reset the phone to stock (currently running Pixel Experience with TWRP installed) but am worried that it will brick the phone if it tries to reboot during the flashing process. Also, I believe that the fact I can’t force boot into fastboot with volume down/power buttons proves it is a hardware issue?
Any ideas are very welcome.
I think unless you have access to an EDL authorised account it's better to not flash MIUI at this stage. Risk of bricking the device...

Exactly the problem I am going through. It's all started today. I am currently running stock MIUI. It keeps boot looping if I do not plug the charger. But once it's plugged, it will load up normal.

I did flash stock MIUI in the end. Did not brick it, but also did not fix it. The phone now turns off immediately after being unplugged every time. I got myself a black Friday Poco X3 Pro so I'm now selling this phone for parts in UK

It could be a buggy PMIC issue similar to https://forum.xda-developers.com/t/...android-11-0-vayu-bhima.4267263/post-85119331
Third-party batteries are mostly crap and probably the original battery is completely drained and the BMS isn't allowing it to be charged as a safety measure?
