MT7 - TL10 Charging issue when phone switched off

Dear all,
I have the MT7-TL10 Chinese Version Gold, Rom MT7-TL10V100R001CHNC00B123SP03. The phone is rooted, unlocked bootloader, CWM. I have a problem when the phone is switched off and I want to charge it.
I plug the switched off phone into the original Huawei Charger but then it won't charge correctly. It seems to hang and I also can't switch it on. Only when I unplug the charger and wait for a minute then I will be able to start the phone again.
Also when I don't switch it on and leave the phone connected to the charger , the battery gets warm but it isn't charged. Also there is no charging animation. It shows only the big battery symbol with the green flash inside.
When I charge the phone while it is on or switch it on without having it connected to charger it is no problem at all. Any idea? Software Issue?
Thank you very much for any help pointing me in the right direction.
Have you tried reflashing original stock recovery?
I tried this way and worked for me...

It is because CWM recovery.
When you rooted flash original recovery back
I was charging P7 switched off and had CWM recovery and it always went after 10 mins. to bootloader from no reason (yes while switched off) and phone didn't charge just 40% was there ..
I flashed original recovery .. and problem solved..

[Q] Galaxy s2 wont turn on/boot into recovery/ download mode

My girlfriend is still using her s2 still she loves her phone but now suddenly the phone stopped working.. it wont boot into recovery or download mode to flash new rom.. also I checked with 3-4 batteries.. any solution for this or the end of story?
pls help me out guys
thanks
It looks like your phone just died. Thats funny. Check if your Phone charges or not when you connect it to a charger. If its not charging. Then its probably a Hardware problem like water chocking etc. If its charging then we can proceed Further. Don't forget to put A working battery in your phone.

Charging problem

I have my galaxy note 10.1 N8000, not powered on for so long. Aftr like three months i decided to power it on as i wanted to use it, sadly it did not... Other time it stucked in samsung logo not going any further. Now when i try to charge it only the battery icon appear in the middle of the screen but it won't give the charging animation just only tge battery icon... If i try to boot it keep on restarting and restarting just ending at samsung boot logo... Any idea wot could be the problem and how i can fix this
Try a 24 hour charge try a USB charge .
Or replace battery .

galaxy note 10.1 not charging + other devices...
first note .... I'm nt a developer or otherwise... but I have studied batteries for 3 years professionally ... and as I found out .. to re initialise your battery in this device ... ( I have done this several times ) you need to open the device and disconnect the battery... then reconnect it ... then just charge as nomal no special time ..button press needed ( for note 10.1 ) ... the problem arrises because the firmware cant boot with a flat battery correctly .. normally when a device is flat the firmware is set up to restart the devicwe when its re charged ... but if the device is left for a while or the battery is old .. 1 year plus ... ( yea its a fine threshold ) the device will not boot and end up in a loop or stuck on start up screen ... I have noticed his in a number of devices ...the only way out of it it is to charge the battery ... ...example in a nexus tablet you have to charge the battery via wires , inserted into the battery ( there are two ) ... then the device boots .. but if you let it go flat ... u have to repeat the process.. same in the note 10.1 ... you can actually charge the battery to full capacity as normal .. but the device still wont boot ( I verified this ) .. the only way round this is to charge it .. for a hour or so then .. open the device and disconnect the battery and reconnect ..... plenty tutorials on line ..easy to do ....3 screws and clip back off and disconnect ... reconnect .. charge and boot ... the prob seems to be as I said in the firmware in the device as when it was made tested they only used new battery's !! never a old one ... its one for developers to sort out ...oh btw I have not ever lost any data on the device ( photos .. accounts etc or anything by doing this ) hope this helps .. ...

phone won't charge !! (only with samsung s7 charger when he is turned off) crazy !!!

so... I encountered this crazy problem that I never seen in any other phone and I had a lot
I've got this one plus 1 (stock operating system, unrooted and locked) and he wont charge at all (when he off or on), my charger and cable are original and they do charge other one plus one (I've got 2 of them).
he wont charge with other chargers and cables.... except Samsung s7 charger when the phone turned off.
I've tried resetting the phone and it didn't help, I cant unlock and flash because the computer don't recognize it (even in fastboot mode).
I even took it a part and tested the battery... it seems ok.
I've run out of ideas :silly::silly::silly:
so if any one of u encountered this problem or have an idea ill love 2 here it
tnx

MY XZ premium wont start with button

Hi Guys,
I have charged my phone XZ premium with non OEM cable
And sudently it siwtched off and i tried to start it without succes, i put the original cable and then the phone start charging but the strange thing is when i disconnect the cable and try to switch on the phone noting happen only when i put the charge and i wait for the phone to show the charging screen then i push the power button and the phone start.
Even when i try to restart my phone when the phone wont open ( like it was switched off and not restarted ) i do the same thing agin put on charge wait the screen and push the power to open the phone.
another thing the phone take 6 hours to be fully charged ( there is no more fast charging )
the battrey also drains too fast
i wonder if someone could help me if its just the charging port will the replacement solve the problem or i have to use my phone this way and not take the risk of open the back of the phone and repalce the charging port.
thank you in advance
