[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.

fastboot doesn't react when connect to computer / no device shown

Hello all, I have a strange problem on my xiaomi 8 phone.
Every thing works fine, the phone is BL unlocked, with global rom installed and can be OTA-updated.
Now I want to re-lock the Bl (because of google pay), so I booted to fastboot and the strange thing happens. When I connect to the usb port of my win10 pc, nothing happens, the device manager also show no new device or unknown device. And I als connected to my ubuntu server, dmesg show nothing, and lsusb also show nothing new.
So the issue is, in fastboot mode, my phone seems not be responsed the usb connection. This is boring, because I also accidently replaced the twrp with stock recovery, now I can do nothing on my phone without the fastboot connection.
Any one has an idea or simillar issue and have a solution for it? Thanks in advance.

It sounds like you accidentally relocked the bootloader.
If so you will need to repair the phone in EDL mode by using QPST. There are plenty of how to guides available. You can buy a EDL cable from Amazon

Xiaomi mi 8 hard brick!

hello, i have hard brick at my mi8 .
When i try to press the power button the phone doesn't boot, If i try to go into recovery mode it doesn't boot and same for fastboot mode.
The screen is unresponsive (no backlight) and it doesn't vibrate. When i connect the phone to my computer it is automatically recognized as Qualcomm HS-USB QDLoader 9008 (COM5) which correspond to the EDL mode (i think).
When try to flash any rom with miflash i get the error " cannot receive hello packet.
Can anyone help me ?:crying:

Likely you have too much power coming from your usb ports, use a usb hub such as this: https://www.amazon.com/BYEASY-Porta...jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Now try Mi Flash again, make sure that the lock bootloader (which is checked by default) is unchecked.
Now it should work, be sure that you are using a fastboot rom and not a recovery rom. ( a recovery rom will not work)
Make sure that it is a fast boot for your device : If you have a global device here is a link with quite a few fastboot roms :https://c.mi.com/thread-1899815-1-0.html
If you still have trouble let me know, and tell me specifically how you arrived at your brick, I helped someone with this exact issue a couple of weeks ago, and I was going to link you to that thread. But i can't find it at the moment.

I get the same error " cannot receive hello packet" with hub USB.
MY xioami mi 8 is global version, i unlock the bootloader and make a downgrade with twrp to a older version of stable rom, and when the phone start ,its all ok and login my mi account, and the phone goes down and never more boot. Always in the pc i get qualcom port (edl mode) . Sorry for my bad english.:crying:

I think i need account with EDL authorization to flash any rom. And i can't found anyone to save me..

Try https://forum.xda-developers.com/mi-8/how-to/unbrick-mi8-edl-authorized-account-t3896677

Thank you .. i try this metod but no success

Keep trying with edl, maybe it's a driver issue, but if you can't get it to edl I don't think you can recover your phone ?

You need to use QPST.
Also you didn't need to open the phone, that step is outdated.
Go ahead and read up on installing all of the needed drivers and as long as your phone is linked to you. That is you have the phone registered to your MiCloud account this issue should be fixable.
I dont have a lot of time today or tomorrow. but I am willing to try and help you figure this issue out.

This could be an issue with the PC...happens all the time.
If the battery is not completely dead, or if the usb port is not completely fried you should be able to at least see the port.
It's also possible that you are not in EDL.
Simply Flashing the EU rom over Global will not brick your phone, I have done that myself many times. Was your bootloader unlocked? If not then you will probably need to take it to a Xiaomi Service center.
Does the phone mac any vibrations when pressing and holding both the volume up and down ( at same time along with the power button?
Have you tried alternate usb c cables?
If you have a newer computer with usb 3.0 ports you will need to use a Usb hub., which will downgrade the connection to usb 2?
Is ADB Installed on this computer along with generic android drivers?
is the computer up to date?
Have you tried an alternate user and are you using the admin account?
If you have a device that uses linux, see if Linux will see the phone.
If you have tried everything, and you still you see the phone, and the phone has not been exposed to an extreme amount of force or to water. It may be that your usb card in the phone is fried or there is a short in the internal usb flex cable. ( It's the wire that connects the usb card to the motherboard.
You can Google the steps to make your own deep flash cable, that would help rule things out much faster.
I am going to sleep now. Good Luck.

@tsongming Do you know why he bricked his phone? I mean he just flashed .eu.

5-yes, adb installed with generic usb driver
6-yes its updated and i tried mutliple ports
7-i haven't tried linux
8-and i dont think that my usb card is fried because before that it was working

The EU rom does not lock the bootloader, the developers actually removed the bit of code that will allow MiFlash to lock the bootloader. Whenever leaving or returning to Miui, storage must be formatted.
The problem with these custom roms for the Mi8 is that These mi8 developers do not work together ( like most do, on other threads) These developers are always fighting and arguing and accusing each other of stealing their code, while they do it themselves and they all have their own way of doing things. Ideally every rom should use the same device tree, firmware and vendor...The basics! But no, everyone does things differently.
I would suspect that your phone bricked due to firmware encryption or just corruption. Even though it seems that it can't be fixed, you will surely be able to fix it eventually.
Many people were eventually able to solve this exact issue in the past with success. so start with the basics., and dont give up when or if it fails, just try again on a different device, and be sure to disable Windows defender. Because it's possible you could have your computer setup in a way that it will make this process harder to resolve, temporarily disable the antivirus and firewall etc.
Download the All in One tool: https://forum.xda-developers.com/mi-8/development/tool-tool-one-driverstwrpfactory-t3895807 If it gets flagged, and completely disabled. then your computer is helping contribute to this issue.
If you can successfully install and open the tool, use it to update adb and android drivers and to apply system wide adb access. Next manually setup the phone , even if it claims to not see a fastboot device. and attempted to remove encryption. if this fails find a Linux machine to complete these tasks.
See if you can leave EDL, by pressing and holding the power and volume down. >>>>> Even if you dont see the fastboot screen the computer may see the phone in fastboot.
I definitely believe that you will have a easier path to getting this issue resolved sooner by using linux. If you can "format" ( not wipe) user data, install TWRP and root the rest will obviously be easy.

He didn't format user data, or the file was somehow corrupted

Loosing connection as soon as Fastboot starts

Hi
After googleing a lot and trying at least 1001 ADB and Fastboot-tutorials I still am stuck. I only want to flash my A2 with stock ROM, but as soon as fastboot kicks in the connection stops.
My phone is unstable (how? see below) but not bricked! I can ...
... access recovery mode and fastboot anytime
... establish data and PTP connections to my PC (Win 10)
... use it normally (apps, WLAN ...) as long as flight mode is on!!!!! :cyclops:
... connect the phone with XiaoMi Tool V2 to my PC
but as soon as fastboot kicks in I loose connection.
Meanwhile I'm out of ideas how to establish fastboot-connection.
Here's the reason I want to flash - in case it matters: After an Andorid update (or at least it seems this is the reason) the screen started to unlock/lock erratically. There never was enough time to enter the code, so I made a factory reset. The problem still prevails, but without screenlock (and looooots of patience) I can access my phone. Debugging and bootloader are turned on now. The only way to stop this screenlock/unlock behavior is to turn on flight mode ...
If the phone is connected to a PC I can hear the "unplug sound" as soon as fastboot starts and XiaoMi Tool V2 looses connection.
BTW: Even with many attempts I never managed to establish a connection to Mi PC suite.
And the USB-connection-preferences very often turn to "no data connection". To fix this I usually have to plug out/in or even change USBport or even the computer.
What should I try to flash mi Mi A2?
Thanks and greetings
Phillip

Sounds strange . Does RIL work ? Like gsm and sim card ...anyway you need to buy a screwdriver from Amazon or Wish or Whereever and open your phone ..
Search for tutorial videos on youtube on " test point " . You will short the phone forcing it into edl ( deep flash ) mode . In edl you don't use fastboot but rather qualcomm 9008 drivers .
You can flash stock rom with QPST ( Qualcomm flash tool ) or just the regular Miflash from Xiaomi .
In any case ..UNINSTALL ALL I SAY ALL the stuff you have installed on your pc right now including adb .Reboot .Install Qualcomm 9008 drivers .Then download the LATEST VERY NEWEST version of Miflash that comes with drivers ..follow the instructions to install drivers and Mifash itself .
Then follow video tut to enter edl state with test point
VERY IMPORTANT HAVE MIFLASH PREPARED to flash very soon as in 1 or 2 minutes after you enter edl because there is a timeout after which you will get errors and would have to do the test point again ...
Good luck ..if the phone is stolen or contains stolen parts or you used some bypass to enter it to bypass lock screen once it connects to internet or gsm the troubles will most probably return ..if it was or is just some glitch this will solve it .

Thanks for your help!
I’m not familiar to what RIL is all about. I just googled it, and I guess it works. I can receive SMS when flight mode is turned off and I get a 4G-connection. I can’t do phone calls, but that’s due to the screenlock-problem as soon as flight mode is turned off. I can’t even enter a phone number then … :silly:
I never heard of edl before but found videos. I’ll give it a try. Thanks for all your tips, especially about the edl-timeout. :good:
One last question before I start regarding the uninstalling of EVERYTHING … How can I be sure, I got rid of EVERYTHING? Windows program uninstall showed be "Mi PC Suite", "Universal ADB driver" and "Windows driver package Android USB device class …" I uninstalled all of it.
But I also used Minimal ADB/fastboot and XiaoMi Tool V2 (and probably other stuff I don’t remember anymore) as portable versions. I can delete those fodlers, but is that really enough regarding the drivers that were installed?

sure for the portables just delete the folders

Giving up
Screwdrivers arrived, disassembling the phone was surprisingly easy. Actually hitting the tinytiny EDL-contacts was surprisingly difficult on the other hand. :silly: But I managed. But also with EDL my computer pretends my mobile doesn’t exist when plugged in. I guess there must be a hardware-problem somewhere. A this point I give up and buy another one. Thanks for your support, KevMetal.

Sorry didn't work friend. Are you sure ? Did you remember to install Qualcomm 9008 drivers from Qualcomm ? Remembering to disable driver verification on windows 10 ...try just more time ...who knows ..

I used a computer with windows 7, because I found on the internet that there are less problems than with Win 10 …
