Hi,
my screen of the archos g9 (1ghz, 8gb) is broken.
now i want to use the logic board like a raspberry pi.
i have bought a mini hdmi to hdmi cable.
i removed the battery, so do anyone know if it will work without the battery (by just plugging in the usb cable?)
which pins should i connect to let it boot?
Hopefully someone like scholbert can help me with this problem,
Nick

i have the same tablet as you and my battery still slowly discharges while plugged in if im actually using it. just a thought but maybe youll have to put the batteries back into the tablet
although thinking about it since your not using the screen at all it wont be drawing any power and from what little i know im pretty sure thats the most power hungry part of the machine.
Yeah, but I tried to boot without battery with no success
On some things you need to connect 2 pins to get it working

You can try... but i guess you'll need to tweak your Android system a little bit to make it work.
For example, i found out that Android refused to start up completely without the touchcontroller connected to the internal I2C bus.
Another thing might be the avtivation of HDMI.
Never tried it though.

No, plugging the USB cable is not enough. But you can power it up without batteries. There's no need to connect some pins directly, though it might be useful to similate the NTC. Read on to get it work.
As you know i use my A80S mainboard for experiments and i use a LDO to power the board instead of batteries. You'll need some soldering skills though!

As stated above this won't work.
Please see the attached pic.
I use a simple wiring with an LDO adjusted to 3.8..4.2V and connected this cicuit to the battery solder pads on the mainboard. Completely unsolder the battery wires first.
To avoid temperature warnings i soldered an additional 4K7 resistor at the NTC solder pads.
You may use any adjustable LDO which is capable to deliver at least about 1.5A max. current.
The example in the pic uses the LDO from Pandaboard.
It is adjusted at 4.2V, which is the approximate maximum value of a fully charged LiPo cell.
The datasheet could be found very easily in the web, to get further information.
Happy hacking!

thanks for your post, i was on holiday so i couldn't replay earlier.
seems like i am just going to connect an battery then
If i get some money i will try the way without the battery
i can't use the board for something else so this is a nice "hack" project for later
Big thanks
About a month ago this charging problem started overnight. Using the original wall charger and USB cable, current_max in GCC was about 200mA (instead of 1000mA). Somebody suggested a factory reset, which I did (restored apps and settings with TB). Problem still exists and is getting worse. Till now I was able to unplug and replug the charger a few times to bring it up to 1000mA, but now the current randomly goes down during the charge (esp if I use the phone).
The only thing I haven't tried is replacing the charger or cable, but I don't have another one. Any suggestions? Thanks.
how did you check this? an app?

Yes, used Galaxy Charging Current.

I think it's down to a damaged usb port on the phone. I have pretty much the same thing on my phone since the cable was yanked out of it whilst charging a few months ago. I have several chargers and some are better than others...depending on the cable. I also have issues with connecting to my pc....I have to not touch it otherwise it just disconnects.

But I have no other problem using the USB port apart from this? Is there anyway I can check it? Or shall I just wipe the phone and send it to be replaced?
I have found the Xperia Z2 to be an extremely slippery phone and it dropped to the floor quite a few times already, but the last fall seems to have finally damaged it. Now, when I connect it through USB to either a PC or power outlet, it will no longer charge. I can exchange data with my PC, view the external storage etc. just fine, but the charging icon will keep appearing and disappearing irregularly, about once per second. Meanwhile the battery gets drained instead of charged.
I now charge my phone through the magnetic port one the side of the phone, which is working fine. I would like, however, to know if there is a way to repair the USB port of my phone.
Many thanks

Seems like hard to repair. You would need to disassemble the whole device. I'd suggest you send the phone for warranty repair. Just do not mention you let it fall

The whole glass back panel was into pieces. I replaced it, so I'm afraid that is not an option

Look into the Z2 disassembling videos, but I guess you should bring the device into a professional phones repair service.
@MrTheMan I think I know what bricked your USB port. The damage wasn't from the fall, you just connected the Magnetic charging cable upside down... Didn't you?
If you keep tightly in some points, dies it charge then? If not and still charges intermediate then there are two things. Either one of the lines if the port is damaged or the battery is of center. Remove and reconnect. First clean it's contacts with.a brush and pure alcohol. Do the same on the port.
Mine does the opposite, USB is fine(as long as I disconnect at 100% and don't charge with MHL adapter) but magnetic has the issue.

Hi,
I did connect my magnetic charging cable upside down. And my magnetic port is messed up now. It keeps charging and discharging when connected. It doesn't charge from a USB port and i need to plug in the adapter to a wall outlet for it to charge.
Is there anything i can do to fix this?
Xperia Z2 Charging Problem

Hi, I have a Xperia Z2. My phone have the same problem after my sister put the magnetic charger upside down. My phone right now can only charge with the mangetic charger. My phone warranty already expired. I want to know is it really the usb port bricked? @MrTheMan, Have you repair your phone?

I'm sorry for your loss. It would be extremely hard to repair that by yourself. If you're out of warranty there is nothing you can do about it.

If I remember correctly there is one diode on the PCB that get's damaged :/
I have the same problem, due to magnetic charger..
Surely this is covered by warranty? I'm still under warranty so I will try to get a replacement.
How could they design it so poorly that it can be damaged like this....

Oh, I search some info. The diode just allow electric current pass one direction only. No wonder my XZ2 keep restart after I pressed shutdown because the diode allow the electric current from battery can pass through in opppsite way.
I don't believe it is a hardware problem. You dropped the phone but the USB port is not likely to be physically damaged by a knock. I had the same problem, on a Z2 provided by my company. I have requested a change, got a new one and in a few days the second handset had the same issue too. Two phones, both new, both never dropped, used with maximum care, both with the same problem. The second one wasn't even charged more than a couple of times before failure. And I had tried it as soon as I had it in my hands, just to be sure it worked, and it did, at first. I connected it to a laptop thru USB port (3.0) and it charged. Then updated apps and system to Lollipop, connected it again and it failed. In a couple of days. I'm sure nothing physical happened, unless my USB port fried it. Notice however, that data connection is working perfectly and everything else I connecrt to that port works as well.
I have some mag chargers too, and I don't believe I've ever connected them upside down. The plug is made in such a way the it does not connect if reversed, having one contact circular shape and the other elliptical.
I checked on the Web and there is a number of Z2 owners complaining for the same issue: there's even a video on Youtube showing this exact behavior. Sony seems to ignore it.
I must admit, however, that I'm unable to explain why a factory reset does not solve the problem. Now I'm trying to flash a stock ROM (mine is branded Telecom Italia) and see what happens.

Did you repaired your device. Please relpy this
Phone 2 years.
1. Charged through the USB port on the network 220 (native charger):
It reaches 81-83% of charge and starts to go crazy: flashing red LED charging and says that is / is not going to charge.
In fact, no charges.
I tried different cords and chargers - so everywhere is going crazy with a 80% interest
2. Charged via USB from the cigarette lighter in your car or the external battery:
It's okay - safely charged up to 100%
3. Charged through the magnetic cable:
It's okay - safely charged up to 100%
These are symptoms of what is dying?
Thank you!
Hello, I searched on other threads but couldn't find a good solution,I have 2 issues related to charging.
1. I need to plug the usb ( no matter what usb it is ) around until I see the message "Charging",then if I move it even a bit it stops charging and I have to plug it around the port again.
2. When it's "Charging.." sometimes it's 10% in 3 hours,sometimes it charges like 10% in maximum 15 minutes,my old samsung charger charges my phone extremely slowly ( max 20% in 10 hours ) compared to my father's charger with a better usb ( it can go up to 100% if it's in the "right position" in 8 hours )
I have 2 batteries,each has the same problem,as far as I see there is a problem with my charging port and probably I need a new charger with USB 3.0,should I get a galaxy s5 one? And how can I clean the microusb port? I don't think it's really 100% broken because if I'm lucky and it's in an optimal "adjustment" ( the usb cable from the charger ) it charges pretty well. Can it have some debris in it? If so how can I clean it? Also I'm pretty bad at following instructions on youtube so changing the microusb port myself with would be pretty tough with all that stuff,so I want to try to clean it first.
Thanks a lot for your help I have had this issue for a while and i'd appreciate any advice. :fingers-crossed:
By the way I use the outlet
1. Replace the USB port 2. Replace the batteries.
Search and read for many posts on how to clean the port, but it might be the motherboard is faulty.

i have cleaned the port,issue remains. Isn't replacing the USB port pretty hard for someone with no experience in such thing? Could I try replacing the safety pins or anything like that before going as far as replacing the port?
Pay for a repair, if you try yourself you'll just brick the phone.

Thanks. Can i buy one from aliexpress to save costs?
over the last couple days, my phone has not been charging properly. go to plug it in for the night and come back to an empty battery.
looked into it and it looks like the phone is stuck in power supply mode, i cant change it.
Attempted fixes:
tried multiple adapters
stock LG cable and charger
Lenovo laptop adapter 65w PD
Razer laptop adapter 45W PD
Kopplen powerbank PD +QC 3.0
USB port on APC battery backup
stock magnetic charger does charge, it just sucks and requires the dual screen case vs the otter box i have.
reset phone (restore from backup)
works temporarily then goes back
tried reset without backup
cleaned the port with isopropyl and q-tip
checked for bent pins
the phone charges when not turned on
from what i can tell it is a software glitch, not hardware related. i get this in 2019 but i started using a G8 because i had a few issues with the case (mostly size.)
does anyone have any suggestion on what might help fix this? this phone might be 2 years old but has only been used for 8 months the battery still charges to full and otherwise works great.
i am running android security patch from august so maybe the December one will fix this.
Bro did your problem solved? How did you solved? Please tell me because I'm also having same problem.
Thanks, but select usb configuration is opening for only about Milliseconds and then it close automatically. So what should I do.
I am also facing this issue post Android 12 update. I have to always select Charging mode from the power mode and selecting 'always' does not work. Everytime i connect a charger, I have to select Charging. Mine 'Power' options stay in the drop down menu though. Its a big hassle and need a resolution. Does LG have any helpline we can contact?
Any news? I have lg q60 with that problem. Phone looks like brand new. Cleaning charging port and motherboard doesn't helped.
I have got same issue in LG G8, few month ago it happened with me, but it was fixed automatically.
Now problem is when connected to charging socket, it shows slow charging and charge mobile in 6 7 hours, when connecting USB or other OTG etc it shows Power supply mode and Computer is not showing mobile.
