[HELP]No FASTBOOT AC/USB

Long time ago, my phone had the usb host mode problem when plug in into pc, but can charge at OS. So i didn't bother it because it still can transfer files to PC via USB OTG.
Last month, itself random went into usb host mode when charging and the phone totally cant charge, need to restart then its ok. When i go into fastboot it shows FASTBOOT AC and then FASTBOOT randomly (like gotten shock) and after awhile the problem gone so i didnt bother about it.
Last week, I unplug my phone after i wake up and then itself shows USB HOST MODE, so i tried connect USB OTG and then it didn't works. I thought it was kernel problem so I downloaded ElementalX 18.2 and then i flashed it. Now, after boot, the phone wont charge. It only charge when powered off and RECOVERY mode. Fastboot shows no sign, no FASTBOOT AC or USB, even OTG power. This is strange and weird.
Also, i flashed ARHD 81.0 at older version of TWRP Recovery, and then after i got that problem, i reflash my phone with TWRP 2.8.0.2, at the end it says : "set_metadata_recursive some changes failed" , and the phone can't boot. Luckily i got a nandroid of it so i flash it immediately. It can boot, but the no charging problems still exist.
I later upgrade my TWRP to 2.8.3.0 via TWRP Manager, still get "set_metadata_recursive some changes failed" problem. But, I found out that after i flash the rom, then flash nandroid, when i boot into OS with charging, it can charge in the OS, but not anymore after i went into fastboot or recovery.
And something interesting is, when the phone boot, haven't load the drivers, itself began OTG mode and powered up my powerbank, PLEASE HELP!! Im totally stuck on this!
Does this is a hardware or software problem? Its this the USB board broken or the motherboard? Please respond..
Sorry for my bad English.

E6533 Unable to flash device (no flashmode, only fastboot)

Hi,
I faced with a problem what I never seen before:
The device works normally, its on 28.0.A.7.24. I tried to update with PC Companion, it recognized the device as E6533, and offered new software.
Once process started, it downloaded, then phones rebooted instead goes to flash mode. After it (until next reboot), phone completely gone mad:
overheated, not asked for pin code, also IMEI was not available etc.
I tried with Flashtool too, but holding VolumeDown not works. It close to immediatelly drops the boot screen, and never enter flashmode.
Had anyone meet with this issue? How could I fix it?
Fastboot mode is working fine by holding VolumeUp, but flashmode not.
Thanks for help,
Your driver usb may be update,,new pc/laptop come with usb 3

Phone will not charge/detect usb when booted in Android, only when OS is not booted

Hello,
I had an HTC rooted and after installing busy box it couldn't anymore charge/detect when usb to computer was connected.
If the OS was not powered it would work to charge or give commands to the smartphone via ADB/fastboot.
I have factory reset and relocked the smartphone with fatsboot flash ruu.zip
The problem is that the problem still persists when the phone is booted in Android (no charge or detect usb).
I have currently tried the following actions with no success:
1) boot into safe mode, reboot
2) disable daydream, fastboot
3) charge for 10 min while phone is off, disconnect charger and continuously hold power+volume up+volume down for 2 minutes
Does anyone have an idea what could be the issue ?

Maybe the USB port. You can replace the usb port by replacing the little board (USB port + main mic).

After also cleaning the usb port from the smartphone the issue still appears.
It is very possible to be the micro usb port like you mention. I will send the mobile to warranty as this issues take a lot more time then I am willing to invest in.

[Q] XPERIA SP CAN'T DETECT ANY USB (PC or WALL CHARGER)

Good evening everyone!
I need help so bad, so urgent!
It was happen when i try to install TWRP on my SONY Xperia SP using an amazing stupid way, using flash boot command coz i cant install twrp using flash recovery command, but i dont know why that fastboot take so long time and just display <waiting for device>. So i decided to remove my USB and plug it once again. Suddenly, my laptop show a notif. "USB not recognized" and the blue LED is gone, then SONY logo appear and start to charging and u can hear connect-"Not recognized"-and disconnect sounds from laptop. But, when the display turn off, it's turn on again, and 5 seconds later u can hear disconnected sounds, then charging stopped. Few later, the logo come again and charging again, and the same thing happend. When i try to charge from the wall charger, it can charging normally, but I CAN'T TURN THE PHONE ON. It's like the power button has been disabled. So i unplug the charger and turn my XSP on, it can boot normally. But when i try to connect to charger, it wont charging. So on my laptop, even my laptop didnt notice any USB, and my XSP didn't show any LED.
Help me to fix this. I can't charge my phone except to turn it off T_T. Pls give me a way out T_T.
Status: Installed AOSP Oreo 8.0.0 huashan, not rooted and no cwm/twrp (this is what i need to install, so i can root my phone, the latest cwm i installed gone after flashing AOSP ROM), cant connect to any USB even in fastboot mode (i've installed the driver).
seems like you got dust in your usb port , it happened to me once , i freaked out real bad. just try clearing it with some needle or stuff , also you might wanna use emma to revert your phone back to its original stock firmware.

what's emma? how to use that?
it's a sony developer tool. You can use it to install original os on your phone , you just need a pc and internet connection , here
https://talk.sonymobile.com/t5/Andr...ony-Flash-tool-for-Xperia-devices/td-p/307318
Also , just save the customization file and delete the rest , download emma sony flash tool from google ( latest version ) copy the customization file after installing it.
After it completes install , run it and wait for it to open , it may take some time during its first run.
Now plug in ur phone , while holding volume down button , you should see green light on bottom , that indicates you're on recovery mode or flashmode. The Emma tool will detect device and start installing original firmware on it.

that was my problem. when i plug my phone in fastboot or bootloader, pc wont detect it, it says "USB not recognized". also when my phone is standby, it wont detect any usb i plugged in, wall charger or usb pc.
i've installed latest driver for XSP, and USB debugging's on.
have you read my first comment? , clear your phone's usb slot and then try replugging , if it fails try it on a different computer , the problems usually with windows 10 as it loses recognizing devices after some fail attempts.

Unlocking Tool gets stuck at either 50 or 99 %. "Can't unlock, Couldn't get info"

Unlocking Tool gets stuck at either 50 or 99 %. "Can't unlock, Couldn't get info"
So, I've tried to unlock my phone for 2 months now without any success. I've done basically everything I could think of, but the same problem persists. The problem is that it gets stuck at either 50 or 99%; followed by a message that says: "Can't unlock, Couldn't get info" Also, I've made sure to wait at least 10 days after I've reconnected my account to retry but the unlock tool won't even show how long I have left.
What I've tried:
- Changing USB ports, Gen 2, 3 and 3.1.
- Using a USB HUB
- Reinstalling ADB drivers
- Resetting my PC
- Trying a different PC
- Reinstalling Qualcomm Fastboot drivers
- Different cable
- Resetted my MI account
- Deleted and created a new MI account
- Used another sim card and phone number
I'm quite desperate as unlocking it is somewhat important for me. As a poor student, I can't really afford to sell it and buy another phone to unlock either.
I'm not sure what's going wrong. I've unlocked many (well, 5) android phones in the past and never had any major issues like this.
Any tips and ideas would be appreciated.
I had this issue before , what I did to solve it is :
1)Use Intel system (AMD won't ever work) and enable usb debugging
2)Don't plug in your phone yet, open Mi Unlock and log in till You reach searching for phone step
3)Open Mi Unlock settings and click install driver
4)Make sure your phone is turned on normally and plug it in through USB 2
5)You will see message on pc telling u drivers are installed now check the phone to see (USB settings) click File Transfer ,now Mi tool should say plug your phone in boot loader mode
6)Turn off your phone and while it is turning off unplug the USB , now boot into fastboot and then plug ur phone in USB 3 port
This is tricky and buggy I got it first time and reached the message after 100% verifying but it said I still had to wait some time so when I tried to unlock it after the time passed I had to repeat these steps couple of times to work so be patient
The problem is mi tool needs both ADB and Fastboot drivers to be working but most of the time its only Fastboot driver due to the phone shutting down so its buggy as hell
https://prnt.sc/rbmvam
These are the drivers that should be both working so check them while repeating the steps if you got them both working you are good to go
The first time i tried to unlock my bootloader, unlock tool would be stuck at connecting to the device and couldn't see it.
No matter what i did it would never see it.
So i decided to try xiaomi tool v2 (not endorsed by Xiaomi). I also used a usb hub that i plugged to my laptop usb c and finally my device could be unlocked.
Did you buy the phone used or new?
Does it have a Global ROM, or it is a Global Version or CN?
