Battery charging and connection problem, any ideas?

Hello,
I have strange problem, since today I cannot charge my HD while its being on, when I plug in usb charger nothing happens, i tried charging through PC usb port, and nothing happens.
I cannot even establish connection with a pc, don't get 3 choice menu (active sync, hdd, and nothing) on HD when usb is plugged in.
I suspected that the usb port is defected, but when the unit is switched off, it's charging even though there is no amber led on.
It has original rom and radio in it...
Did anybody had similar problem? The phone is under warranty, should I send it for repair?
Thanks in advance.

Very weird. I would definately advise you to send it in for repair. I haven't heard of anything like this before :O.
Good luck!

Hi, I got the exactly same issue as you described today. Have you got it fixed?
Looking forward to your response.
Thanks,

This has already been discussed:
Battery Not Charging
1.Hard Reset after backing up data.
2.Check if SPL/ROM mismatch - if U flashed a custom ROM or SPL.
3.Short circuiting pins in battery compartment of HD after disconnecting of power/USB and removing battery. (Don't short the battery - it may explode).
Try the solutions, if it doesn't work then go for warranty.
Too many ppl seem to have this problem and no one uses search

I did search it before and got 8-9 pages of results. I tried all the approaches but none could fix it. This guy described the exactly the same symptom I have so I really wanted to know how he ended up doing with the issue before I sent it off for warranty.
The problem right now is really on the USB connection, even in the boot loader mode, it couldn't recognize the USB but it could do it just one day before.
Thanks for your reply. I appreciate if you could have some new ideas for me to try.

Have you tried updating your USB drivers?

Have you tried different usb cables?
Some of my usb cables no longer works. I believe my mini usb connector have become slightly looser and I have experienced a cable will charge the phone but won't come up with any options.
Wotth a shot.

The USB driver seems ok since I used the USB connection to flash ROMs and SPLs the day before without any problem.
As for the cables, I tried 5 or 6 total including the stock one but it didn't help.
As stated before, the only time the phone is charging is when I turn it off completely and it charges fairly quickly. However, the bottom (close to the USB end) part of the phone is very hot during the charge. If I turn it on or put it in standby mode, there is no charge or ActiveSync activity.

I have a similar problem.. My phone charges when I plug it in. But I am not presented with any options and ActiveSync doesn´t recognise the device..

same problem here
I am in the same situation. I flashed back the stock ROM, but with no USB, I am unable to put 6.5 back on....any advice is appreciated.

I sent the bad phone (Telstra T8285) back to the seller (an AUS ebayer) and he nicely sent me back a new phone but the story didn't end here. The second phone worked for one day until I plugged in my usb universal car charger. Damn, the exactly same problem happened again at the very moment I pushed in the usb connector. Now I know what the issue has been. I frankly told the seller what happened and he told me what their repair guy found about my first phone, that the fault was from reverse polarity of power supply. I was very surprised because I have been using the same car charger for my previous 3 PDA phones w/o any issues and it's still working for those devices. What's special about the Touch HD?! Does USB have different polarity specs?
Anyhow the seller said he can replace it again but I need to pay the return shipping this time.
What is baffling me is that the phone can still charge when it's off completely but can't when it's on. Does it look like hardware or software problem? Also the USB can't be recognized in the bootloader mode but it could before being faulted by the charger. Does anyone have experience on faulted connector and is there a fix besides replacing the entire motherboard?
Your help and suggestion is much appreciated. Thanks!

The Advanced config Utility has an option for "USB Charging" maybe you could install it and see if the option says yes?

also me... now i figured out what the real problem
i used my old miniusb car charger about one full day before and the same problem start with me with slight different which is charge if i keep it plug in long time...(start charging after 5 min.)
i'm really lucky by not completly dameged
this issued must be listed and get real answer from HTC compeny if the mini usb for hd is different

[Q] Problem connecting to USB

My phone just stopped connecting to my computer over USB. I went to update Fission to 1.2.1 and got stuck at trying to actually connect my phone to the computer. USB debugging is enabled and SetCPU is setting the USB charge profile, but I don't get either of the notifications I'm used to, and my computer doesn't register that I plugged it in. Anyone else run into this?
About phone states that the battery is discharging as well. Bad cable? Charges just fine over the other charger I have (dedicated wall charger, so I can't swap cables).

Sometimes its something simple. Are you trying to access your SD card? Make sure your USB sync is on USB Storage.

I get this problem as well. If I reboot my phone a few times it seems to start working again.

Yep, sure enough, after a second reboot it works fine. Thanks.

That was the problem, it never even gave me that option. just didn't register that it was plugged in at all.

Always try a reboot when something goes wrong. Id say 75% of the time it will fix your problem.

Might or might not be related, but...I just recently got a Droid 2 to "play with" and noticed that the internal memory can't be read by Astro File Manager or the stock "File Manager". When I plug the phone to my Mac I can only mount the SD card. I'm still looking at older threads but I figure I ask here just in case.

Omnia 7 USB Problem

Recently I've been getting these "USB Malfunctioned" errors in Windows whenever I connect my phone to my computer. It was working fine a few days ago. I've tried disabling USB devices and resetting my computer but it fails to recognize the device. What could be wrong? I've tried replacing the USB cable and I'm running Windows 7. The phone is charging fine so I doubt it's a hardware fault. What do you guys think?

I had the same problem. I bought a new USB Micro USB-B Cabel.
Then it was all fine, no errors, no problems.

But I've tried another USB cable so what could the problem possibly be?

Could be your USB jack in the computer, happens to me. I have to unplug the cable, turn off the phone, then back on, and then plug the cable in and the computer.
The jack isn't so tight on my motherboard so if I move the phone while it's plugged in, it does a quick unplug, plug in, and that causes the problem for me.
It pisses me off cause it could totally f' up an update.

I've tried all the USB ports on my laptop, everything else works fine so it's not that.

Bump, some help would be good.

Bump, guys ._.

Well, I know precious little about stuff like this, but once you've exhausted all other possibilities it might be time for a hard reset and if that doesn't bring a cure, back to the shop, waving your warranty thingy.
Good luck!

I've got the same issue..anyone have any luck recently?

Try it on another computer, hard reset, if that doesn't work, contact Samsung for a replacement or repair.

Phone wont turn on

Hey! My phone ran out of battery. And when i'm connecting the charger it wont even turn on.
I have tried to hold down the safe mode combo, different chargers. When i connect it to the pc it says something like "Windows couldnt recognize this device".
Could it be the battery thats broke or is it the phone itself? Dont have spare batteries to test.

Tried a different USB lead?

Yes, tried different chars aswell as different usb ports on my computer.

Might be a problem with the charger input, when im moving around with the charger it makes the "noice" on widows that its connecting. Just weird that it says "not detectable device" on the screen. Any thoughts on this?

If wobbling the phone side of the USB lead around is connecting / disconnecting USB, and different USB leads/chargers don't fix it, then yes, it sounds like the charger port needs replacing

Problem recognizing charging, headset, and PC connection

Hello boys! I have a very serious problem with my LE PRO 3. Since yesterday, the following is happening BUG: When I connect the charger, it does not load immediately. It only loads if I reboot the device. And if I take it out and put it back, it stops loading again. This also happens when I connect to the PC. The device only recognizes if I leave the cable connected and restart. With the headset the same thing. It only recognizes if I leave it connected and restart the device. I'm on the Cydrass Google edition ROM, and my device is the x720 version. I have already switched to other ROMs (LineageOs, Ressuection Remix, and even the Chinese STOCK ROM 26s, and the problem still persists!) Apparently it's a serious problem recognizing my USB port I do not know what else to do! Please, help me!

even first buy , do you have problem ?

To Vitor_147
Remember, if you change the stock original LeEco rom you cannot say "have a problem with my LePro3", it's no longer the original combo "LePro3" (hardware + software) so expect (and accept) anything (better or worse!) and report the defects to the rom developer.
Now some helping things!
Apart to clean the phone usb c port and to try a new usb cable, you can:
With the usb cable connected, switch the usb debug off (or on) (developer options) then check if your computer detect your phone.
Even if your computer doesn't detect the phone or your phone seems not charging battery, if the usb cable (and charger) is good in 99% of the cases it charges the battery even if not at full charge rate (expect a minimum 4 hours charge time).
Before to give up, the last try is to bring your phone back to factory conditions with everything (but everything!) under the exact conditions of how it came out of the factory, then you can start over there and have an idea of whether the phone has a hardware defect or if it's just a matter of software.
I hope you solve the problem, if you find the right solution please report it here, so other users can learn how to solve this problem! Cheers!

I already wrote this up in Omni thread, so I'll keep it short. I've also been experiencing this same issue for a while now, it first happened on stock rom, reboot solves it. Darko tried a fix in his eas kernel, seems to fix it (so maybe somehow kernel related). I believe it might be somehow related to the usb-c controller, cause I found cases online of similar issues with pixel phones (i believe the controller manufacturer is the same as in our phones). I actually know the exact moment when my problems first began, after I used my OTG adapter to connect a usb mouse. Few hours after that, the phone wouldnt charge.
{Disclaimer - this part is purely my theory}
I think it maybe somehow related to a safety "switch/fuse" of sorts, or something to do with static discharge or something similar, and here's why. I did a loot of trial and error since the first time it happened to me cause it scared the sh*t outta me, thinkin my phone is broken. I am vigilant about careful handling of usb ports and such, (ocd-ish really) so theres no way I physically damaged it, its not loose one bit, cleaned it out, tried wiggling the cable around anyway, has no effect, so I excluded the possibility of a faulty port/soldering. A few occurences to note
No1 - if I plug my phone in the charger first, and then plug the charger in the outlet, it breaks the port, I have to reboot to fix it. But plug the charger in the outlet first, then the cable to the phone - no problem. (Static discharge of sorts?)
No2 - since it started happening, the only way my usb-c OTG adapter works is if i first plug the adapter in the phone, and then the desired usb device in the adapter. If i try to plug the adapter in the phone w/say a usb stick already connected to it - no go, doesnt work.

Oh... I'm sorry for what happens to your phone! It's true the safest way to charge a phone avoiding current surge/spikes/shocks is to plug first the charger to AC outlet, then the usb c plug to the phone, then the usb plug to the charger. If possible, never plug/unplug the charger to/from the AC outlet if the phone is connected to the charger.
When the phone is full charged, first unplug the cable, not important which side first, then unplug the charger. If the phone is still charging, better unplug first the cable from the charger side to avoid micro spikes on the usb c port.
If you cannot obtain a normal behavior of the usb c port neither with reflashing the phone with the "qfil" system, perhaps a logic port of the usb c port is burned or simply in undetermined state, in the last case a total battery discharge may reset the logic port state and the phone can works fine once fully recharged. I'm sorry I can't help you better at this time! Cheers!

@orsonbear, thats my train of thought aswell, micro discharges occuring while plugging/unplugging causing the controller to freak out, or potentially damage the tiny connections (micro usb only had 4 wires vs 24! in usb-c). But I believe the problem lies somewhere on the software/firmware side, mainly because a reboot solves any issue I have. And also I just remembered, the first time it happened to me was a couple of days after I updated my firmware while updating to 19s, or 20s, cant recall precisely. Anywho, for me it's a minor nuissance, not like the OP who can only connect his phone once before rebooting (I can go for weeks before it occurs).

Yes,
I thought about letting the phone down completely, and see if that does not happen anymore!

Same problem here
Days ago it start happen, exactly how you say, i never change the stock software and it start happen randomly, I have to reboot to recognize anything that I plug into the USB c port, I try factory reset and change from 26s to 23s and it keeps happening so maybe I'm pretty ****ed, someone help me, in my country no one will fix the port u.u (sorry for my English).

Hellao! I'm having a very similar issue, charging works fine and the pc detects the phone but OTG and the audio on my headset is not working. Did someone of you find a solution to this problem?

1. x720, x722 or x727?
2. Where did you buy the phones? (Store names)
3. What kind of USB-C cable were you using? The one that came in the box? Have you used other USB-C cables and adapters to see if it works?
This could be hardware failure due to a lack of QCing from LeEco (just your average hardware issue) or a USB-C cable issue. It's ver. 1.0 on all LeEco Pro 3 models (right)? So I can't say it's the cable for sure. Has anyone attempted to take the phone apart to replace the port? do they even sell the port replacement?

Similar problem for me. About a month ago my headset stop working and the phone did not recognize it at all, tried with the adaptor to 3,5 mm jack and did not work either. Charging worked though.
Found a replacement chip with usb c port and ordered. Yesterday i replaced the charging port, but still the headset do not work at all, and connection to PC does not work ether. Charging still works as usual.
I ordered the phone from grossoshop 7 month ago with their rom. Tried this evening to upgrade the rom from 5.8.018 to 5.9.020, still grossoshop but no difference... It should not be a hardware problem as i replaced the type c port.
Should i try to flash another rom to see if there's any difference?
Any other suggestions?
Thankful for any ideas

Have you tried switching cables? Could you have broken a contact or something while swapping the port out? Have you tried putting the old port back in to see if the computer recognizes the phone with it? Unfortunately you're gonna have to try everything, even if opening it back up again is tough. LeEco phones aren't exactly known for their build quality. Are you x720? Well, flash whatever ROMs you can, I guess. Might as well try everything.

Yes, I have tried to switch the cables so no problem with them. Have not done a swap back again as the problem seem to be similar as before, so maybe a change to a different rom will be the next step for me. If change of rom does not work, maybe then I'll try to swap port again.
And yes, It's a X720
Thanks for fast reply.

Maybe it's not plugged in or attached correctly so the phone doesn't detect it. Sounds like a hardware issue to me, in all honesty. I once took apart my iPhone 5 to replace the non-functional home button and it wouldn't work no matter what I tried. I had to remove the battery, reseat it, and then attach the home button again. It finally worked after a reboot.

just report in on this thread, I as well recently purchased an x727 experienced the similar issue. Basically as described above no matter what roms i test is always have some sort of camera errors when charging.
sometimes charging doesn't work or camera doesn't work I have to reboot to get it to work. extremely annoying. I think it is hardware related.
Anybody else have a solution?

This my advice to anybody considering buying this phone don't why you will get zero support from letv.
I got luckey I have zero problems with phone .
I recommend spending more money and getting a supported phone by the maker.
If you do buy one buy it from Amazon where get a warranty on it.
