I'm working on my defy, but I have no flashed system into it, only twrp.
How can I charge it so I can flash a new system?

I can enter like 3 things, bootloader, stock recovery and twrp.
When I power it off it wont show charging battery, but maybe it does?
There is also a white led light on while a usb cable is connected. What does that mean?
Maybe when I get to the option between 'recovery' and 'continue', I should press comtinue and it will be charge-able there?

Thanks a lot, Im trying a long time to install cm11 into my defy, will get to it, I hope.

You can try the "MacGyver".
USB cabel with open ends to put in to the Batterie contacts.

Or...5Volt source with fix current of 50-100mAmps. Some houres Charge. Controlled by VoltMeter.
Max. 4.1Volt ... no warrenty....on your own risc! !!!!
Just google it ...

Did that, took a usb cable and connected it to an adapter with 5.0DCV output.
CUrrently seems that my battery is invisible to the defy. I can't turn it on with it, only if im connecting it to the charger or "MacGyver". When I try to charge it, the battery shows 5%, after a second it's 20%, and after a cuople of more seconds it's 60%, and it wont reach 61%.

Sometime charging shows a question mark (?) on the charging meter (while powering on).

What should I do? charging it with another cable? Flasing again with sbf_flash? Let it charge more?
Also the bootloader wont start. The farest I made was a blinking screen which after that the defy rebboot again and again if im keep trying to get to the bootloader (Power+volume up pressed).
Can't reach recovery, the battery charging jump insead.

I need some help here.

Looks like your batterie is dad/empty.
Let it SLOWLY charge to 4V by 100mA. Check the Volts! No overcharge!
If you have, try a adjustable Power supply with 4Volt like a full charged Batterie , cant overcharge and connect to Defy.

I did MacGyver and Batterie together in the Defy !!! DANGERUS! !!! Very filigran ... shortcuts ...
so Defy have Power to Boot in to bootloader or recovery. Supported bye the accu by higher consumtion.
How good is your Batterie? ??
How about 5euro for a New one.

You can also try to charge the Batterie in the OFFed defy over 1-2 days.
Without Android charge control it is very slow charge

I used TCH-520 (AC charger model) with "Output DC5.0V --2A", So I need DC4.0 --100mA ? And I must stop it before 100% ?

If you have, try a adjustable Power supply with 4Volt like a full charged Batterie , cant overcharge and connect to Defy.

You mean those with the clock that I can choose my Volts? But I only those one which are used for organ. How can I connect it to a phone? And do you mean that with an adjustable power supply I can't make things worse?

Yea, Done that too, Big mistake.

so Defy have Power to Boot in to bootloader or recovery. Supported bye the accu by higher consumtion.
I dont really understand, can you explain again?

How good is your Batterie? ??
How can I check? I know it's a ''HF5X. Also I see it's a 3.8V. Should I find a charger with 3.8V too?

How about 5euro for a New one. Option (:

What is OFFed mode? If I connect my defy while powered off, It will turn on and show me battery charging (While not really charging ofcorse)

Without Android charge control it is very slow charge Yes, Annoying. Better manual charging.

Answered inside quotes. Thank you for helping!

You better look for new batterie.
When you charge and it is to quickly getting more and more %, than it looks like a defekt batterie.
When you try to go in to bootloader, it takes more energie then the batterie can deliver.
Dont forget, USB is not direct connected to the CPU, there is between the batterie and when the CPU starts to run, the Defy takes to much energie for a weak batterie .... the Volt level go down below 3.5V ...reboot ...
A empty batterie have 3.6/3.7 Volt.
Full charged 4.1/4.2Volt..
You can replace for Tests the batterie with a 4Volt source, like a powerstation with setable output.
When you sleep, you leave Defy charging but off. When Defy boots to charge, just off by push and hold Power until its off.

But better you look for fresh batterie.

MacGyver + batterie + defy = 5Volt will be redused to 4Volt by the batterie to get Power to Start the Defy. Very tricky ... be carefull
AND NO Blame to me

If the battery reduce it to 4V by itself, shouldnt it be safe?

SAVE ??? , when you connect the batterie with the 5Volt-USB cable,
then batterie Volts increase from 3,6Volt up to 4Volt,
when charging is not stopped with 4Volt, its getting overcharged.
Should charge very slow, with a 1/10 from the capacity of the batterie.
So , with a 1500mAh batterie you should load with 150mA for 10 houres,
so its more save, becorse slow, but have to be controlled too, maximum 4,1 Volt.
This is controlled by Android regulary.

You can put the USB-cable in the batterie connector-slots and both together in the Defy.
So the batterie stay connected to the 5Volts and
will be charged from USB, even in the defy, bypassing the charge-controller.
So you can try to boot.

For a short time you can do so.
Later the batterie get higher and higher without charge-control, so will overcharge, DANGER !!!
