I'm trying to find UART pins on the Bip so I can flash FW without the need for bluetooth. I modded the watch a bit in order to test some pinouts. After probing for a bit with a multi-meter, the four pins along the bottom edge of the top of the PCB seemed the most promising.
My UART to USB converter broke, so waiting on a new one in the mail. But based on my multi-meter readings, this is my best guess for the pinout, but won't know for sure until tomorrow when my new UART debugger comes.

As I said on the other post, you should use st serial wire debug line, denoted in this picture as STM_SWDIO and STM_SWCLK (go here for more information github.com/amazfitbip/documentation/issues/4)
How open the bip?
How have you open your bip without broke the glass on the screen?
I have tried to charge my bip without the origigal charger and have inverted the polarity, now also with the charger no longer turn on, maybe is only a fuse or the battery is dead.
can you write the ic name?
Need a ST LINK V2 to flash an recovery no pair or no turnon Amazfit Bip/Lite/
i have backup for flash by ST LINK need 3 Pin, SW-SDIO, STM-SWCLK, GND only for flash

Is it possible to use st link mini?
I will definitely just using direct cable instead of using metal pins another time
The direct pins are easily to break.

Hi,
My usb port on my xperia broke previously and i had i repaired but now its broken again. Would it be possible to re solder a brand new usb port as the the guy at the phone shop says he might not be able to re solder it next time.
Any response is greatly appreciated.
HI,
It is possible almost everytime but, MIGHT take very long time to resolder, if copper pads are took off the PCB. Therefore, it mustbe soldered back on other pins.
Anyway, it is possible.
.
Thanks for your replay.
I know that the outer big pins are the ones for charging but are they inner small pins for data connectivity?

Yes - outer are GND (-) and VCC (+) - inner D+ and D- (DATA). One pin is unused. Here is the pinout:

Thank you for your reply.
This was very useful and now i can out smart the phone guy when he says in can only charge meaning he hasn't soldered the inner one on.
So hit Thanks pls
If that guy was the technician, ha propably knew that. But there maid be a reason, why he didn`t soldered them - maybe it wasn`t possible due to damaged PCB...
Just guessing
..
I did get my xperia fixed once but it only charged and when ever i connected it to my computer it only charge and did not connect to the computer. Is there a solution for that?
So your phone was repaired after damage? Am I right, that it wasn`t repaired by yourselve?
So, you could find out if data pins are soldered - download Terminal emulator
here.
Then open it and connect your phone with PC via USB cable. Once phone is connected on both sides, type "dmesg" and see output. There must be something like this:
<6>[23469.853208] *********** Charger Type: HOST PC
<6>[23469.853384] Charger Type: STD DOWNSTREAM PORT
<6>[23470.708433] msm_chg_usb_charger_connected
If charger type is DEDICATED CHARGER, data pins are not connected or not solderd properly.
Thanks a lot.
It`s OK - you're welcome
I've got a phone with a broken USB too. I've got a new USB port and was looking for some information on how to do the soldering. Thanks.

Hi, if you don`t have any experience with soldering (of anything) - Don`t do it, you may damage your phone permanently.
yes,is possible to diy cradle for table s and can be recognise by it.
start from the power plug,
let's name the contact of plug from end to 1234
from the note on power adapter,we know 2 is dc+,3 is dc-

contact 1 is about the cradle.tape contact 1 then connect the plug.
look,system show cradle setting ui!
so,diy cradle is so easy:
just make some cradle size ok,
tape the 1st contact of power plug,and set it on the cradle.
done!
it will work same as official cradle
Hey!
First of all: That sounds really great!
But I do not have a lot of experience with such things so I do not have any idea how to construct such an adapter (ok, the technical way is clear so far, but how to construct the case of the adapter?)...
Does anyone have an idea?
Thanks and kind regards

Let me know where you can get the DC plug from, as, I'd like to make a car adaptor, as far as I know, it's a Sony Special and not available (yet?)!!!
Wow, this is a great idea, <robin>! Thanks!
I tried this, and although the cradle function is activated on the tablet (as shown in the OP), it didn't charge after I taped that pin 1 on the charger plug...

Hello, the other day i connect my n9770 to the computer, and this turn of and not restarted. It say: "Error! Please plug out charger!"
I've opened the mobil because had to change the screen and I have looked if he had any bad soldering, but everything seems ok.
The Flash tools not recognize the mobil.

Same Problem showing in my phone..how to solved ur problem....pls. Reply me as soon as possible
This means 1 of 2 things.
A. The phone is liquid damaged, and the solder around the charging port is corroded.
or
B. The charging port is coming a little loose, or some of the pads have cracked a bit.
To fix A. Clean really well with 91% Rubbing Alcohol and toothbrush, and take a little heating gun from a rework station, temp set at 349C for me, and move the gun back and forth over the port slowly and steadily, until you notice the solder melt, lift the gun away and turn off, let the solder re-set itself. Try to charge it then.
To fix B. try A's solution first. If it doesn't work, buy the charging port off the internet for your phone, heat up the solder, and gently pull the charging port upward off the board, insuring the pads are staying on the board. Heat the solder back up, and place the new one in the exact spot, in the exact direction. Let it set, cool down for 10+ minutes, and try it.
For liquid damaged phones I clean the board really well with a mixture of Alcohol and scrubbing bubbles foam on the entire board. Taking the board out of the phone of course.
Your Phone Is liquid damaged
you might change the charging port of your device this will solve your problem
hi, my phone (infinix zero2)fell down and went off, i thought the battery was low and plugged it it now brought out erro pls plug out your charger, what should i do?
Error please plug out charger solution
watch it - youtu.be/zxMfXKLte2o
Warning, your warrantee is now void. I take no responsibility for damaged devices doing this mod, nor any issues that may arise in the future from doing this
Just felt like posting this little mod I did to a Nabi 2. After re soldering tge wires on the oe charge cable it finally couldnt be fixed anymore. It didnt take long for me to get frustrated with the flimsy, thin charge...thing, and rip it open to see what could be done.
After a little poking and prodding I found the simplest solution.
It seems the 5v pin on the usb port is electrically separate from the charge circuit, but they all share a common ground. Soldering directly to the usb port was all but impossible because of how the port is designed, and my soldering iron isnt that tiny, but I found a resistor tied to the 5v pin.
I soldered a wire to the resistor since it had a decent surface area to get a solid solder joint, then soldered the wire to the positive pin on the charge port. The result? Micro usb charging.
I have found a bit of a glitch however. Plugging the device into a pc does properly kick it into usb storage mode, but because of the low amperage, it begins to cycle the charge system between charging an not (as if contantly plugging and unplugging the device) the same happens if you use a charger rated lower than 1amp or a bad cable.
Besides that it seems to be doing fine

Thanks. Not sure why I didn't think of this years ago. Been searching for the original cable to try and make some use of the tablet and decided to see if it was possible to charge via usb. Couldn't have been easier to modify and it works perfectly.
Hi guys,
just buyed a Mi Box 3 Intenational Version (MDZ-16-AB) two weeks ago. Suddendly, after two days of use, the power supply died. Bought a PSP one that works. The problem is that now it don't pass the boot animation, it restarts. It sometimes even show "Android" but then it restarts again. I've tried every guide on the internet for this model and nothing works. I've tried:
- using the images that you only have to put in USB disk and reboot into recovery
- putting the update.zip into the USB disk and then "Install from EXT" -> "udisk"
I always do a factory reset before install an image.
Nothing works, unfortunally. The box stills bootloop. I'm out of ideas so I came for your help.
Do you know any way to get the Mi Box back to stock an working? Do this already happened to someone?
Thank you.
The MiBox uses a very specific 5.2v 2A power supply.
Have seen many problems with more common 5.0v power supplies that dont match MiBox spec.
The huge internal heat sink is the reason for 5.2v requirement.

Are you sure that can be the reason? The only 5.2 2A adapters that I can found costs 20€. Thats almost half of what I paid for the for, would not want to spent that without certain.
Here's the charger that I buyed:

Hi guys! Just to close the subject, it was the charger. I stripped down the 4mm x 1.7 mm of the original charger and a USB cable and put them together. Using the improvised cable with a iPad charger (5.15v 2.1 A) the box lives again .
TL;DR : use a charger with the exact box specifications or the box will not work.
