[Q] opo not being detected by my computer

Hello! Im new here
The thing is that I bought a bricked OPO today hoping that I could fix it. I've been like 4-5hrs straight trying and nothing!
The real problem is that my OPO is not being recognized by my computer. (Im running Windows 8.1)
When I connect it to the PC the device vibrates but no sound, I go to device manager and it's not there (not as QHSUSB_BULK, not as UNKNOWN DEVICE, not as nothing, it just dont exist)
I installed the Samsung drivers, OnePlusRestoreTool, Bacon Root ToolKit, OnePlus One Toolkit and nothing seem to work...
I tried to get it into FastBoot mode but it ony vibrates every 10 consecutive seconds I hold the vol up + pwr button and NOTHING happen, screen remain black and no sound by my PC recognizing the device...
I tried alternate USB, alternate cable and nothing...
If you guys can help me that would be awesome!
Thanks, and sorry for my bad english.

First of all thanks for your reply.
I have seen this thread but as you can see to uninstall the old driver I need to:
' Go to Device Manager, right click on the bricked USB device (QHSUSB_BULK or Qualcomm HS-USB QDLoader 9008) and go to Properties, click on Driver, then select Uninstall. Check the box to remove driver files, if prompted...'
But the device is not seen by the device manager.
Someone suggested in an other thread that I need just to press (not hold) power + volume button.
I will try that and let you know.
By the way what is 'test mode'?

[Resolved] [Q] I hard bricked Lenovo A536 Mediatek/ MT6582Mdevice

I tried to downgrade the kitkat version because I couldn't update my apps, using a flash tool.
It then shut down and now does not turn on at all. When I plug into the computer the USB gets into a cycle/loop of connect and disconnect. Please help me if you have the time.

no. But I think it goes on '''META MODE'" ONLY on the computer for a few seconds.
Thanks for commenting.

Check device manager in your pc when you connect your phone, is it showing MTK 65xx preloader

I used this one.
forums (dot) lenovo (dot) com/t5/A-and-P-Series/Lenovo-A536-stuck-during-firmware-upgrade/td-p/1744571[/url]
I downloaded the latest firmware from
"THIS is the latest original ROW firmware (PC Flash Tool installation)"
This whole guide was fine, it worked for me.
But the problem was when I tried to downgrade the firmware to an older version.
I tried to replace the lastest official firmware with this one ROM Android 4.4.2 (older official needrom(dot)com/download/lenovo-a536/
sorry can't link websites yet

Thank you so much for staying with me to solve this problem. The phone is fixed.
I followed the
"
For MT6575/ 77
With the battery out, hold the volume up, don't let go & plug in the USB cable will activate META mode for few seconds...Typically, you need to click Download at SP Flash Tool before entering META mode or it will auto disconnected...
"
except I downloaded the lenovo a536 stock rom.
the only thing I did different was that I plugged in (META MODE) and THEN pressed download or else the usb would never be detected (they both show different COM numerals.)
After that I firmly held the whole usb into the phone during the whole flashing, or else it might get automatically disconnected again.
Then I updated/upgraded to the latest firmware, And it is all optimal. :good:
THANKS AGAIN !!!

What do u mean by "it is constantly going off while installing"
Does it boot in recovery mode? Please be as specific as you can while posting questions.

[Q] Lenovo Tab 2 A7-10f bricked

I was following the steps from xda guide as i seen it from the link bellow :http://forum.xda-developers.com/android/general/guide-lenovo-tab-2-a10-70-root-t3279322
in the third session "3. Install Custom Recovery" at the fifth step
"Connect the turned-off tablet to the PC. Recovery will flash in a matter of seconds and you will get a big green OK on the software."
i got te following wrong message: error (2005) not start bootrot (something like that)
So i made the huge mistake to plug - off the usb cable from my pc and i tried to repeat the fifth step the device didn't respond so i plugged it off again and i tried to boot it up but it wasn't responding at all.
Is there any way to boot it and hard reset it?
PS. The tablet is fully charged.

Did u figure out anything?

Hi guys,
I bricked my lenovo tab too with format tab in sptools (what a dummy I was :silly.
The tablet was nearly dead, not visible in windows (device manager) nor linux (lsusb) and no vibration or display at all when I pressed the power button.
I managed to get it revived by following these steps :
0. prepare sptools on the computer in download mode (download only) and ready to flash a rom (waiting for a connection)
1. remove back cover on the tab (begin with the usb port on top with your fingers and use a plastic tool to get the job done) and unplug the battery pin
2. press vol+ and vol- (not that easy without the backcover) and hold until the end
3. plug in the usb cable to the computer
4. plug the battery pin
5. prey your computer to recognize the tablet and start flashing
I hope this can help.
And don't forget : NEVER use the format tab in sptools with this tablet
Enjoy

Thank you very much, it helped and now works like a charm

Hi there . So I bricked my Lenovo as well with format tab and now it's not recognized by computer at all even after trying with battery unplug . I suspect that it's a driver issue and that I should install windows 7 instead of using 10 . Can somebody pls tell me what windows and drivers were you using when you u bricked it . I am 6 years late lol.

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.

I ordered a new USB port board, will let you know the results!

Any results after changing the usb port?

Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help

Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.

Stuck! Xperia Z5 E6653

Can anyone please help. im stuck in a difficult problem. I cant enter recovery, my phone just loops, and i cant connect it to my pc. Just getting USB device not recognized. The last usb device you connected to this computer malfunctioned, and windows does not recognize it. I dont know how to add a new software or restore a backup, and i got a seious battery drain issue. Hope someone can help me. Im on Slim X rom on a E6653.

Download a MM, LP or Nougat firmware.
Let the phone charge and go to flashtool
Load the firmware you downloaded check all the wipe section case and put your phone on flashmode (vol - and stick USB cable while maintaining vol -)
Let flashtool do it's work and once done it should be OK

I have tried that, but my computer cant fin my phone, so i cant use flashtool

I found out of it. Had a faulty usb cord. Im happy again.

Hehe no problem
