Redmi Pro Charging port broken/shorted - Xiaomi Redmi Pro Questions & Answers

Hi so I bought the device about 3 months ago and it was awesome from the get go everything was great until today when i plugged in my device for charging. After a while i noticed it was charging very slowly so i instinctively disconnected and reconnected the type a usb cable from the charger. On reconnecting there was no indication of charging on my phone. I reconnected it one more time and nothing. So i took out my voltmeter and connected that in series. The moment i connected it it started to restart continuously. On off on off and i had to disconnect it to make it stop. I thought it might be a cable issue so i tried a micro usb cable with an adapter. Same result. Then i switched chargers, again same result. Whenever i disconnected the phone it would stop restarting. On one charger it did stay on but the voltage dropped to 3 volts and amps up to 2.3.
So i have concluded from above stated facts that the charging port/ board is kaput. If anyone has any suggestions on this please let me know.
After this i started to search for a replacement type c charging board for the redmi pro but i cant find any. Any help in finding one with international shipping would be appreciated.
Please leave Ur thoughts on my conclusion.

replace your usb c cable

Thx. But luckily i was able to repair it. Woohoo

Anyone know where to get a replacement usb charging pcb ?

was it a easy fix or did you replace the usb board?

Sorry for the late reply. I searched for the port on various websites when i had the issue but couldnt find anyone who sold redmi pro parts. Luckily however i found a seller on ALIEXPRESS who said that he did have it. He had asked me to pay using mi max charging board which was around 7 usd and then he would send The redmi pro charging board.
Sadly i cant find the seller who said this so i cant share the link here.
What u could do is go on aliexpress, find the largeat stores with the widest variety of xiaomi charging boards and ask them if they have it.

For me it realy was an easy fix and fast one too.
I was out of option at the time so what i thought of was that if i could find a 4 or 5 amp usb brick i could probably melt the shorted portion of the circuit. Ofcourse that in itself is dangerous because it could ruin the phone completely.
Anyways sadly i could not find any such power bricks. When i had almost lost all hope i thought of trying this out in my cars charger because car is already running on a DC system and is capable of providing alot of current to the usb charger, which is just a sort of regulated stepdown transformer. So hopefully that would provide the power i need. I started the car and then connected the phone. The moment i connected the phone to the charger the cars rpm lowered slightly for a second as if it were under stress and then went back to idle. AND MAGIC! It was fixed.
What it did was provide alot of current to the phone which heated and melted the shorted circuit. Since then ive had no issue with the phone.
It might be different for u though so i wouldnt recommend just doing what i did. If u have waranty claim that. If u r out of all options and u feel like ur phone is a dead piece of metal (like i did) then go ahead. But do not hold the phone in ur hand or anything while doing so because it can be dangerous in a number of ways. DC is much more unforgiving then AC.
Hope this helps.

how to charge htc 8125 with no original usb cable and(or) without orig. wall charger

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks
charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!
no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway
I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.
I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.
seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.
Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.
thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging
//pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml
so, any more help will be appreciated a lot
thanks

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!
Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.
hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?
So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.
old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.

[Q] Faulty USB

Hi, today I plugged in my Bravo to charge and it intermitently went in and out.
I unplugged to avoid anymore damage, I'm sure it is a hardware problem, because when I hold it in a certain position it would charge and wont go away. I tried with multiple chargers, cables and on the pc, to no avail.
My question is: How can I fix this? I feel comfortable disassembling these devices. BTW it is no longer under warranty, not that it matters as I am not in the US.

Where are you from? Try buying that USB port on ebay or other place!
Thanks. But I couldn't find the usb port specifically for the bravo. Is there a known compatible spare parts, would the defy's do?
I managed to get it working, I bent the inner stick on the usb port a little bit down, and it is working fine for now.

If it is working its really good, I think you could try with a defy's one, you know the share lots of things in common!
Awhile ago I found the culprit for this problem that kept getting back every now and then. I'm posting my solution for reference.
It was the 1000mA charger that I was using, now I'm using a 700mA and haven't had any problem since, I doubt it was the 1000mA charger as it is working fine with other devices. Perhaps the Bravo couldn't handle it.
When I tried with other chargers they were of the same amperage, with the PC maybe I was desperate and didn't notice it was charging fine.

Troubleshooting - a500 won't charge - Is my power supply or tablet dead

As of last night my A500 will not charge. I left the device overnight and unfortunately now have Zero charge.
- My charger makes a noise, I think it always did, so I'm assuming the charger is OK.
Can anyone confirm that the chargers give off a kind of electrical buzz when working?
- I get no light at all on my A500. If the charger is OK I'm thinking something has gone within the tab, be that circuit or battery.
Any ideas or tips here?
- Sadly I do not have a multi-meter to test either the charger or the tab, no friends with a similar device, I've lost my proof or purchase (which is painful and rules out warranty), and am a bit stuck what to do.
Any ideas?
- I've heard/read that allowing the power to drop too low can cause a problem. Obviously Zero is bad in this case.
Can anyone confirm this rumour or suggest a fix?
- I did try entering recovery and resetting the battery stats - whether this made things worse or not is unclear - it certainly did not help.
ANY HELP OR IDEAS WELCOME (bear in mind that I have spent quite some time searching and trying other peoples' ideas already though.
Thanks,

Quit guessing and get the charger checked
In reply to myself and to help those with a similar issue.
Yes a charger my buzz when good OR bad. The trick to seeing whether it is working or not (aside from it charging the pad) is to see if it gets warm -- no warmth, probably broken.
As for measuring with a multimeter the trick is to insert a paper clip into the small hole in the plug and measure the voltage between the outer plug (negative) and the paperclip (linked to the positive). Few multimeters have pins that will fit inside the super tiny plug on the A500 charger so the paperclip is your way in - obviously be sure not to short circuit the thing!
There are many chargers available out there. In Australia Jay-Car and **** Smith both have perfect chargers, the correct type, voltage, amps etc, they even come with multiple pins -- sadly none fit the A500!
My solution was to go to Infinity who are a provider of Acer spare parts. They have the correct charger and are easy to deal with BUT -- It's not cheap! They want $40 for the charger and a further $30 for the little bit on the end that gives the plug its nationality. In most cases we do not need this though as we can reuse our old one, but hey, not cheap all the same.
Still, it works and I'd rather be ripped off than get the wrong thing and blow the mother board.
NOTE: if you do get a charger from anyone other than Acer or a supplier of theirs - be sure to match every detail of your current charger - especially polarity.
I had problems with charging on my A500. When I plugged in the charger the power button would turn orange for a few seconds and then start flashing white.
I took the back cover off and found that the wire to the centre pin of the power connector on the tablet had almost broken off. I touched it lightly and it came away. Re-soldering the wire fixed the problem, it now charges as expected.
After fixing it I measured the charge current. It starts at a small value for a few seconds and then jumps to full charge rate. It seems there was enough of a connection to handle the small current but as soon as it switched to full charge current the voltage drop across the remains of the connection was too much and charging stopped.
Charging problem
I too just experienced the no charging problem. I looked up how to open up the tablet and tried to trouble shoot the problem myself. My problem turned out to be a very easy fix. The Posative lead on the back of the charger port had come loose, a simple touch of the soldering iron and its fixed. I thought since I had it open I might as well go ahead and change the battery too since it was 4 years old. Its an old tablet and time to turn it into a hand me down for a lucky niece or nephew

[Q] USB Charge/Connection issue

Hey all,
I have a Galaxy Nexus which recently started to act up on his USB port saying it's constantly connecting /disconnecting to the charger with no cable present.
Device: Samsung Galaxy Nexus
Edition: Maguro GSM
OS: CM10.2 nightly + CM11 Alfa
Chargers: OEM, generic, battery & laptop
Cables: OEM & generic
Reproduceable: sometimes
This week I noticed my phone did not react immediately when I plugged it into the charger. Mostly after some fiddling (bending the cable away from the screen) it would start charging. After pulling the cable or removing the charger from the wall, it would generally take 5 to 10 sec for the phone to realize I pulled it- this used to be instantly.
Strangely, when the phone said it cannot charge it can be connected to a computer as Media Device without any problem. Charging only happens after the fiddling again.
Looking into BBS, it cannot give any stats because it says the device is connected constantly to a charger. Android original battery monitor stats are also a mess but it does not say I am connected always.
Every now and again the phone also starts making notifications as if he was constantly connecting and disconnecting - leading to frustrated looks of the people on my train...
Cleaned out the port - no success
Hit it on the train table - no success
Reset, battery pull, flash, different OS - no success
After this all I think it will be a hardware issue. Nothing seems bent and no pins seem to be sticking out. Removing the back and checking the mother board showed everything still intact and all connectors still in place.
I'm guessing now the micro USB connector of the phone has somewhere some corrosion or a pin out of place but not visible to the untrained eye.
Can someone shed some light please?
2 screenshots to show you what I mean.
No, I am not up for 9 hours and lost only 10%... Battery life has become horrible since this issue. It just thinks it's constantly hooked up to a power source and I think it's no longer power efficient because of this. I already disabled charge connection sound because it was driving me crazy ...
Please help if you know even half a solution. I can also post a photo of the connector but the problem is that there's not much to see there...
I think you have problem with charging circuit >>if you have solid knowledge in electronics you can simply replace it
replacing this port in attached pic will solve your problem .... otherwise you can fix your own port because I think one of your USB port pin are touching the ground chase of your motherbord
Thanks for the reply. Somewhat saw it coming I would have to replace something...
I already looked on some sites like ifixit to see what I could do but I thought to have seen that the Motherboard was in one big piece.
Could you please give me the website where you found this or the name /article code of this component?
Thank you

try to follow the steps on the link it is very helpful http://www.ifixit.com/Guide/Repairing+Samsung+Galaxy+Nexus+(Verizon+LTE)+Micro+USB+Charge+Port+%26+Main+Mic/9641
and you have nothing to do with the motherboard just take the old charging port and install the new one
Ordered a new part. Hopefully it'll work...

Not able to charge

Randomly my note 3 has started having issues charging. I'm not quite sure why. It gives an error about needing the factory charger, however I'm using the factory charger and usb 3.0 cable. Sometime a reboot fixes it, but not always. I've tried using different charges, and even a regular usb 2.0 cable and it still does the same thing. Is the port maybe going bad? If so, has any one replaced theirs? Any help is appreciated. I have wireless charging, but there are definitely times I need the quick charging of the oem charger.

That is the problem with intermittent behavior. It is difficult to say that "after" is caused by "before" because you don't know when the intermittent behavior will show up and when it will not. Any experiment in the presence of an intermittent behavior runs the risk of coming to a conclusion that is an "ex post facto fallacy".
I suppose your hypotheses of a damaged or loose USB connector is the most probable, given everything else you mentioned, although since you don't have a second Samsung/OEM charger, a problem with that specific charger can't be ruled completely out.
Note that the USB 3.0 Micro-B connector "extra" pins (the part of the connector which is not used by a USB 2.0 micro connector) doesn't have power/ground in it (there is a shield ground, but this isn't the same thing as the power supply ground)... so your tests with a USB 2.0 cable don't resolve anything about the connector, but do indicate that the problem is probably not your Samsung OEM USB 3.0 cable.
Those mini-usb connectors are pretty horrid mechanically for devices that need to be plugged in several times daily; I guess the phone industry assumes that consumers will toss their devices after two years, so the power connector only needs to survive about 1000 - 2000 plug-in/removal events.
The only conclusive way to eliminate the possibility that you simply have a failing USB connector would be to use a spare battery charger - and that means buying both a charger and a spare battery if you want your phone on almost 24/7.
Sorry I'm not more help.
Common issue. New cable may be needed.
My 2 cents...i had this problem while using custom rom..however, taking the battery out for about 30 sec..switching back to stock Rom using safestrap rebooted and it all went back to normal charging ok. Went back to custom rom again no issues after that...

I tired this last night and unfortunately it didn't fix the issue. I have multiple OEM chargers and none of them are working correctly. Once my wife gets home today I'll try her cable to see if it makes a difference. I'm really hoping I can get this figured out because I have never received a good refurbished phone from vzw under warranty. I may even resort to just using the wireless charging and ordering the oem battery/external charger combo. Has anyone ever replaced the port itself?

FWIW
I have never done this repair, and it's not too encouraging that the iFixit teardown in Step 7 mentions that the USB connector sub-assembly is "glued to the phone". (Looks like step 5 could be skipped maybe).
I note that the images in this eBay listing shows "SM-N9005" stenciled right on the assembly ... I wonder if this sub-assembly would be any different from carrier to carrier? Seems sort of unlikely that Sammy would silk-screen a specific variant Model # on that assembly if it were the exact same part on all variants. (But maybe you can inquire of the eBay seller - at least the piece prices are pretty inexpensive). I didn't spend much time searching; maybe there are other sellers with the SM-N900V assembly.
good luck

I found some videos on youtube of people replacing them, it seems like it's one of the easier parts to replace on the phone. I'll probably give it a try. I'll post the result if that fixes my issue. From doing some reading about the part, it is semi carrier specific because where the antenna cable goes. I'm hoping to get this done sometime this week. For now I'm just using my wireless charger to make due.

That does make a bit of sense.
If you find a supplier for the SM-N900V part and it's in the same price range, send me a PM with the link... I might buy one on speculation (I typically don't buy a new phone every two years so it might be a good idea to have a spare part on hand just in case the port goes bad).
I installed a new usb port and now it seems to have fixed the problem. My usb 3.0 cable fits snuggly again and I'm not getting any weird messages. Hope this helps any one who has the issue

I'm glad you were able to fix it yourself.

Good news! Do you have a URL for the part supplier?
I experienced this today with my Note 3. I have all kinds of charging cables and right now after a few reboots a random USB 3.0 charger that I got from Amazon is doing the job. I noticed the phone no longer charging when I plugged it into the USB 3.0 port in my computer last night but I was doing a heavy amount of tethering so I didn't think all that much of it at the time.
