Hello guys, I got a Z2 which the USB port is not working, neither to charge or to transfer data, I have to charge it with a magnetic charger. I had successfully rooted and installed TWRP through WiFi ADB and then flashed latest sony stock BETA. A week after that I notice that the recovery was gone! No led flashes on boot and I couldn't enter in TWRP, so I thought that I need to get it back, because I can't use USB on it so TWRP is the only way the have backups and so. I tried to reinstall TWRP through WiFi ADB but then the nightmare began... After the Z2 rebooted, BOOTLOOP!
I know, I should fix the USB port, but I can't do it right now, it's kind of expensive here in Brazil...
So, is there anyway to get it working again without the USB?
Unfortunately no.
Sorry dude.
You need working usb port for that.
You could try ordering the component from China (like aliexpress etc), it should be cheaper there.

Hello. My Redmi Note 3 SD run CM14.1 with kernel Radon 3.5. It run smoothly for a month until 3 days ago. It cannot be charged as well as cannot connect to PC as USB (PC cannot recognize it). For half a day after that, the phone suddenly returned to be normal as nothing happened. And today, the same error happened again. I tried plugging it in through fastboot mode and it worked. So I thought It would be software error, I used Miflash to flash MIUI Global stable 7.1.5 with the hope that it can fix it. But not. It successfully flashed to MIUI but the problem is still here
Is there anybody got the same problem? Can anybody help me? Please!!!
p/s: Sorry for my weird English, I'm not a native speaker.
Try this:
The problem might be with your USB cable and/or your phone's micro USB port (worst case, your phone's motherboard/IC - let's hope that isn't the case). Try using different Mi USB cable or different device with the same model to find the fault. Make sure you have the required drivers installed. Hope this helps.
Hello
I made a thread on reddit in the subreddit of my ROM (/r/LineageOS/comments/cccbtu/pc_does_not_detect_xiaomi_redmi_note_4/) regarding my issue and they recommended that I come here (I hope that's the right place.)
In summary, the notification that usually shows when I plug in my phone, to change the USB configuration from charging to MTP, does not show.
I've tried everything I can think of (different ports, PCs, cables, etc.) and nothing seems to help.
"adb devices" shows no devices both on normal boot and TWRP. The only thing the cable does is charge.
I'd be very happy to fix it.
Thank you!
First it's a software issue so the hardware is fine
Second i suggest getting an sd card with the official stock rom on it (version 10.1.1.0) to fix the reading error since it can't be readed even on twrp
If the problem still presists
I suggest to change the cable or the phone socket
Try another cable then see
I have a H96 Pro Plus 3G32G ZH01-S912TVBOX-V3.0 with a green board and 7.1 firmware.
I suddenly stopped turning on, so after some research I found a solution of replacing the capacitor to 1000mf at the DC jack. Now it turns on but, wont boot. TWRP recovery was loading to splash screen but blacked out after that. I tried using the USB burning tool to flash the firmware, but it gets stuck on 7%. The SD card method also stopped at the same place and the device just powers off.
After trying a number of times with a few different firmwares, the SD card no longer boots at all and the USB burning tool still stops at 7% formatting.
I have a full TWRP backup of my stock firmware, but no way to restore it. This is the TWRP filename in case this helps.
2019-05-19--07-24-49_q201_9377-userdebug_7.1.2_NHG47L_20171020_t
Is there any way to make something flash to the device? Even if I can just get the recovery or bootloader working so that I can flash the backup.
Thanks for your help.
Here are some photos of the board.
From the log file, it's look like unstable usb connection, have you tried other usb male to male cable? the shorter the better

It's one I've used on numerous occasions with other World Cup devices in the past. It has always worked with other devices, it seems more like a problem with the device.

From where you found solution to change its capacitor. Was it necessary. Being an Engineer, i dont think that it could be a capacitor rather faulty usb ports or power adaptor

It was on freaktab. The original problem was the box not turning on and the new capacitor worked for that. But unfortunately I found that solution after I had already tried to install the firmware unsuccessfully so the box is bricked. It would probably be fine if I had not tried to flash the firmware.
Hello,
I am currently in a dead end with my Poco F1, and would like to check with you before throwing it away.
I was using my Poco in version 12.0.3.0 with TWRP installed and root with Magisk. Due to the last days errors of apps that shut down when opened, I decided to reinstall the system using TWRP, but I made a mistake and installed version 12.0.2.0.
I don't know what installing this version did, but now the mobile isn't starting MIUI anymore, it's starting by default TWRP. Furthermore, something has been changed in the TWRP version installed that touchsreen it's not responding, so I can´t use.
The problem is worse since, for a long time the transfer of files to a PC via USB cable isn't working on my Poco, so Windows is not able to detect the mobile in fastboot mode either. I tryied reinstalling drivres in many ways, and still not working. The poco charges perfectly, so I don't think the problem is the USB conector, maybe is a motherboard related issue, so changing the connector I don't belive will solve the problem
Recap:
- I can't start MIUI (the version has been corrupted).
- I can't use TWRP (it has been corrupted and the touch screen does not work).
- I can't install from fastboot (Windows isn`t detecting the Poco with the cable connected).
- I don't think changing USB connector solve de USB data transfer problem.
Any ideas or should I throw away the smartphone?
For me it's a real pitty, because I don't like the new Poco F3 or others phones on the market, most of them don't have 3.5mm jack or microsd card slot, and are bigger, heavier and more expensive than the Poco F1.
Thanks to everyone.

Hello,
The issue with error of apps was probably due Webview which Google pushed an update and fixed it. For more infos read here.
Now, to the current problem...how did u flashed previous version? Clean installed or Dirty installed?
What Desktop system do you use? AMD or Intel? Your PC can detect the device while you are on TWRP? Do you have twrp.img on ur device so you can reflash it via TWRP?

Thanks for your answer.
I noticed that the issue with the apps is due to webview after breaking my phone, next time I'll think things twice before flashing anything.
I did a dirty installation, I thought I was installing same version (12.0.3.0), but I was flashing 12.0.2.0 on top of 12.0.3.0 without cleaning.
I tried both desktop systems: my laptop with an Intel CPU, and a PC with AMD Ryzen 9 3900X. I also tried 5 diferent USB-C cables that are working perfectly with others Android devices. When I look for new devices in the device manager of windows I can't tell any diference on listed devices with or without connecting the Poco. As I said, maybe I have some hardware issue in the phone, because file transfer was not working for many months.
I can't install anything via TWRP because touchscreen don`t respond to mi fingers... I remerber that this happend to me years ago when I installed a wrong TWRP version, but don't know if that is the problem.

Well, somehow you need to manage to flash MIUI again via TWRP or Mi Flash Tool.
Perhaps if you redownload latest twrp.img and latest official miui 12.0.3.0 and transfer them to USB OTG or external SD Card and then put ur OTG or external SD Card to your phone and flash it from TWRP. Since you was able to wipe system as u said before you will be able to flash twrp.img into "Recovery" make Clean Install (according my guide) and flash MIUI.
I'll try if connecting something via OTG make the phone responds, but the main problem with TWRP is that appears to be corrupted or something. I cann't use it because touchscreen don't responds to me, and nothing happens either if I try to use it with volume+ and volume- buttons, I see TWRP but I can`t interact with it.
Thanks again for your patience.

I tried using OTG cable in TWRP and nothing hapens, TWRP don't respond.
Seems that I'm in a dead end, I ordered an USB PCB spare part to try if is posible to repair the USB data transfer connection replacing it, becuase looks like is the only way I have of flashing a new clean rom.

If you have AMD system try the AMD Fix in my guide. Also try this guide to install drivers.
Finally I could solve the problem.
I bought a new part of the USB port PCB from aliexpress, I ordered one that claims to be original for around 15€, not the 2€ ones.
I replaced it and the data transfer is working again, so I could install the ROM via fastboot from my PC.
I don't beleive that the PCB I replaced is original, but works like it is, phone charges properly and seems that didn't loose signal.
Thanks to everyone.
