Hello guys , i have a difficult Problem with my tablet over 2 mothns now . I cant fix it at all
First of all ,
My talbet is from China unbrand , with no naname , i cant even find any information about it
The only thing that i know about it , is that i brought it from Chinavasion and called "Nemesis"
So , 1 day when i charge it , my charger took fire , and melt a llitle bit on Cable.
( My charger was 0.3A 50/60 Hz Output 5V 2.5A 2.5mm ) So i had to buy another one , When i took my new charger(The new charger is a biger one , and i can choose Volts that i want ) , problems started .
Now my Battery is always stucked on 100% (battery Icon) , i dont know how % battery i have and when it dies , alla my options are gone such us date and time.
I open my tablet, nothing is burned so battery is ok ( i think) , so i think i must take a new charger , or Firmware Problem
Also , if i charge it for about 5 min then pull out the cable and then charge it again , my screen start to touch alone in some places.
So i tihnk its a firmware problem ,But i dont know anything about firmwares or roms.
When i tried to write on terminal ( Getprop ro.build.description) shows me
JR003H eng.1sd.20121105 .170909
Also i know that i have a duel core RK3066 tablet if this can help a little bit.
Can someone helps me ? I dont know what to do it exept it throw it from my window.
Thanks.
I am here if someone need some information .
If someone finds me the solution i have a present for him ( i dont know if this allow here on this forum :angel: )

Ok guys i think i installed a wrong firmware and now my tablet doesnt charge at all or opens...
I think i brick it, now there is a solution or i must throw it ?
thanks.
I don't know about the rest but one thing I do know is that problem when charging that the screen misbehaving while charging, it happens to my phone whenever I plug in a slightly different micro usb wire, the stock cable used to work fine but when it got damaged then I found the same behaviour in my phone, I had to search alot to find a compatible wire which did not cause this problem.
I hope this info helps.

Hi ...
I recently flashed an android 4.0.3 stock firmware with odin , when I plug my charger it shows "battery disconnected" , so I told myself a factory reset should do , it didn't , so I flashed a rgui miui rom that I had , still the same problem the battery is not charging , so the phone shut down and I try to plug my charger, it shows me the usual battery icon that shows when charging while the phone is turned off and beside it a yellow triangle showing a battery inside it with a "/" on it , is that mean that I should get a new battery ? thanks for the help
First is to clean the USB port see all the other USB problem posts for how.

first try out wat jje said,,,,,,,then if all ok an same prblm ,try a new flash via odin (stock rom)
SOLUTION 1: (tested and working) I have tried another sgs2 battery, and the problem did not occur.
That means, you need the buy a new phone battery, even if you have warranty, since I beleive that the battery is never covered under the warranty.
SOLUTION 2: (not tested) wipe battery stats
The problem with the battery can occur because :
1- Not using the charger sent with the phone ( For example, using the playbook charger, which is twice as powerful and will wreck your battery, or an LG charger *slightly different voltage*)
2- I beleive the sgs2 software prompts you to unplug charger when it reaches 100%, because if you over charge it, you also risk damaging your battery on the long term.
3- Batteries have a life, Laptop batteries range between 1 to 2 years for example, then you need to keep the battery plugged so it dose not run out of juice really in quickly.
So on the sgs2, it is a very battery demanding phone, so battery issues are always there, if battery is always experimented with, it will get ruined.

Hi Everyone,
After doing a deep search i did not find the exact problem I have.
Specs:
Phone: SGS2 i9100
ROM: CM10 Nightly 08.09.2012
Kernal: CM Stock
You can see the symptoms of my problem in the video I found below (it wont allow me to paste link with less than 10 posts so i shortened the URL)
youtube.com/watch?v=BCyp1iCTW2M
This is what happened:
1. I had an Adapter from Car Outlet to USB so i connected my phone using it but it seemed they did not like each other.
The phone was stuck on a black screen so I restarted it and noticed I lost 40% battery in those few minutes, looking at BBS i saw the RIL wakelock so decided its just a coincidence and i'll let the battery drain all the way to calibrate it at night (the phone worked perfectly fine)
2. After the battery was fully drained I connected it to the PC to charge and turned it on and everything was fine, noticed it was at 0% so after a few minutes it turned off, after doing it a couple of times i let the phone charge "turned off" (thought maybe its low voltage of PC charge) through the whole night
3. at morning it did not charge at all, I managed to "almost" turn the device on but now the battery is really drained so i cant even do that
4. when i tried going into download mode (just to see if my phone is OK) i managed, when i am trying now i get "Battey is to low, cannot download"
5. I cant get into recovery mode, but i tried it after all the process above so its probably because of low battery
6. I tried it on 2 diffrent batteries (unfortunately my old one was also drained before)
- Anker 1900
- Original Samsung 1650
I am going to get an AC charged and try using it.
Any Ideas what should i do or what the problem is ?
Thanks in advance!

This is the way to go. First make absolutely sure the battery is charged, if possible by testing it in another device. With a fully charged battery it should be possible to find out if your phones hardware is still fine, especially the charging board.

Hi,
Thanks for the reply!
So far i got an AC charger for the phone (not a battery only cradle charger kind of thing) but getting the same problem.. it just wont charge the battery through the phone..
I'll try to get a fully charged battery to give feedback that the phone is fine and not bricked in any way as i mentioned before.
If everything is fine i'll see that the battery is chargeable when not completely dry and we'll be smarter after that.
in case it really became unchargeable and it is a problem in the charging board as you mentioned
Could you please expand on the functionality of the charging board ? and whats the process for fixing/replacing it ?
Thanks in advance!

Excellent! If it is not bricked then chances are good that it is 'only' a battery/charging problem.

If, in the end, the phone does not charge by the USB connector (no matter if from PC or wall plug) then it could be worth to replace the flex print with the USB connector and parts of the charging electronics. This flex print is quite cheap and you can get it from ebay. With the help of some video from youtube you should be able to replace it yourself
Well,
I have an update on the issue.. unfortunately can't say its a good one..
I've tried turning on the device with a diffrent battery (charged) and it workes perfectely fine.
since I live far i didnt want to wait a month till i get the USB flex from ebay i went to a repair lab and let the test the phone.
Unfortunately it is not the USB Flex but a deeper problem,
apparently the u500,u501,u504 parts got fried on the MB and they don't have them at all.
I am going to try to restore my phone (using a full battery) to the way i bought it and try go to the store and work the warranty (it voids as soon as i changed ROM), going to have to read a lot on how to do it perfectly and erasing traces of changes (go an old nand and need to unroot afterwards)
do u know a good guide for restoring the phone to full stock ?
Also,
is it possible to buy a complete MotherBoard for the GS2 or its not worth it ?
Thanks for the help!

There are quite a few guides around here that deal with unrooting and getting the device ready for official service. Personally I just make sure the flash counter is reset (TriangleAway or JIG) and then flash a stock firmware.

You might find one on ebay but I think replacing the MBO is not that easy, even though never did it myself.

I had the device opened several times. Replacing the MBO should not be too difficult. There are only some screws and connectors.

If the warranty wont work than I saw its around 150$ but if that will solve it it might be worth it instead of buying a new phone.
Thanks Again!
They are a lot more than that unless you are in USA/Canada.Theres a firm on eBay that give you $30-$50 for your old board,and they sell theirs for around $180.
Samsung would be around $250...
Sent from my GT-I9100 using xda premium
So.. After a long time (!!) I have an update.
No lab fixed my phone as everyone said its "unfixable" or need to replace some parts that they don't have... so I did what I planned to do.
I took a full battery from a friend
Restored the phone to full stock (the same official "partner" ROM I got the phone when bought it (even putted Android 2.3 on it LOL)
formatted my SD card , and of course did a "Triangle Away" to reset the flash counter
basically returned the phone to the way i bought it..
Since I still had around 2 month on the warranty I went to the store i bought the phone from and they accepted the phone based on warranty, as i didn't install any ROM's (LOL )
Only TODAY after more than a month and a half of wait, while it was at their official lab, after that was sent abroad to the Vendor itself, after nobody was able to fix it I got a new phone (14 days used phone) so, considering i was ready to throw my phone and by a new one it turned out OK.
since no one was able to fix it, it was probably a major problem.
Of course its better i got a new one, since even if they fixed the issue, who know what else it might effected so its a very good result.
Don't know if this helps anyone a lot, but at least its some closure to the thread.
Thanks for everyone who helped here!
So, anyone having the same problem here? I already reported this issue to Sony support forum. And yeah, theres alot of people having the same issue like this. The LED will start blinking right after it reach 90% above. Its very annoying to check it all time.
This is happened to me almost everytime i charge my phone. This is kinda software bug, or something to do with rooted or recovery installed? Since i have a rooted and recovery installed on it. Or maybe the problem is with the magnetic cable usb?
Nopee.. Nothing of that sort for me ...

My dad's got the same problem after 80%. He has Z2 running completeley stock, no root etc, so it must be software's fault.

Happens to me aswell connected via USB on my pc.
So, i bought a new brand magnetic charging adaptor called "MAGNECTOR X2". This solved the blinking charging issue. Yeah i was right, theres nothing to do with lollipop update or software. ROFL! I recommended for u guys also.
Stronger magnet
More stable
Can be used with all type micro usb cable
Easy to carry
*Search at youtube "magnector x2" for more detail.

No. Unfortunatelly he doesn't have any other charger.
The docking station isn't original, however it was charging fine on kitkat.

I suggest u try with another diffrent magnetic charger, if the prob still there, do a clean install by using flashtool. Hope that will help, since my problem already solved by changing the usb cable/magnetic charger it self.
For your information, charging your phone to 85% or 90% rather than 100% doubles it's battery life cycle (as in amount of discharge/charge cycles it can survive through).This is something you should care about as the back of the phone is not openable.
I'd want mine to blink after 90% :laugh:

He won't buy another cable due to OS bug, and also he won't wipe his data for sure. We will see if the next update changes something.

redmi note 3 charging fix
I too had the same problem and I tried flashing in fastboot and other things stated in internet. But I replaced charging port newly purchasing online. If your mobile is still in warranty period fix it in service center or replace it yourself. Check YouTube for how to replace charging port. You can buy charging port from eBay or Amazon or any other desired site. Check your phone has 24 or 30 pin in charging port board of your phone. Because Redmi has two variant. If you have any doubt just google it.

I don't think it's ROM or kernel,
I have the same issue.
It doesn't charge even in power OFF mode, and also with the STOCK ROM.
I changed the charger/cable. doesn't work.
I use an app called 'ampere' and it's saying the phone is discharging. but the cable is plugged.
probably it's the charging socket.

Had the same problem & solved it
Hi,
I had the same problem - when connecting the charger (any charger/laptop etc I tried) the phone started charging, then stopped and started charging randomly.
What I did: Open the phone, brushed the USB board, took dusk and dirt out of the USB port, and it works like a charm again.
I used this instruction video and followed the steps exactly, apart from taking out the USB board which isn't necessary if you only clean it. You will need some tools (most importantly a small screwdriver and an (old, used) toothbrush.
I'm a new user so I cannot post the link. Search on youtube for the video with the title: How to Replace Xiaomi Redmi Note 3, Note 4 , Redmi 4A , Redmi 4 and Redmi 3s Carging port ( Pin )
Good luck.
I have solved this problem
Turn on USB debugging from developer mode then put your phone on charging for 1 full night in switched off mode ...
It will charge normally
.
.
.
Tell us if its work for u ... your feedback will help others
its work for me after researching for 3 days
If you guys are using fast charge or QC chargers with custom kernel, Sorry to say that charging and discharging randomly is because of that. You are gonna destroy zener diode which stabilize current passing thru it. If input current suppress 5V it will burn your zener and your device will completely stop charging. (Only working aftermath way is removing burnt diode)
I highly recommend you guys to stick with stock chargers. Or use kernel that limits its current to 2100mA (approx) (Agni kernel has it) to avoid damage to zener diode.
P.S:- Once you replace your USB board, I am pretty sure that you will face some serious network issue like most of users (those changed board) are facing.
Hello,
I think this is really weird.
After a few days I´m not able to charge my phone anymore.
not on: Aukey QC3, IPhone 5se, motorolla, no name charger, original, my work notebook USB port.
Nothing charge it.
Until I plug it into my home desktop PC.
Can someone explain what is happening?
I think it is a ROM bug, since I could open fastboot and the mi flash tool does detect it. And it is now charging (again) ... this happened the second time now...
Any tips?

Yup, very strange. I think I read something somewhere about a similar issue.
Most people think there USB port is broken. But I think they have the same issue but just no PC which works (as noted my work notebook does not work, but my desktop PC does...) it was also detected in in fastboot mode on my work PC (just to low on power to try) ...
I had a simmilar problem (well, I still have). I removed the back cover and removed the battery cables - and plugged them in again. After a couple of tries it started charging again. But yesterday my phone fell and since then I can charge it only via a huawei charger. The Xiaomi one doesn't work. One thing is for sure... If you get a red blinking while the phone is turned off and charging, you must let it rest for about a minute in order to plug in an other charger and start charging again ...

Hi ,
Some people got this issue fixed by returning back to stock ROM.
You can try that.
In my case the charging port was busted so I got it replaced from service center

I was on stock, after the second time I switched to global developer version. Let's see how it goes...
But why should a buster charging port only work on PC? And after that normally? (for a week or so)

Yes in my case no charger was able to charge my phone only USB was charging.
So I went to global dev ROM using EDL mode and then went to service center. They replaced it in 30 mins. Also my charger was not working so they replaced charger as well.

Can you try with MIUI stock ROM and tell if you are still facing the problem? This should mostly be the ROM problem like you said.
