So i want my original rom back and i want to use the SmartFLash method .
i did everything but when i plug the phone the com port is not filled ... what can i do ?
i tried to do the operation from another pc with APX driver but it was the same
any solutions?
CHEERS
did you hold the volume down button while plugging the usb cable into the mobile phone? did the pc report any usb device plugged in and what was going on with the mobiles display, did it show s/w updating or just the logo?

i hold vol down , the pc didn't report any usb device but the s/w updating it was showing on my display ... when the phone was plugged I entered in device manager and i saw something like : Others devices : Unknown device ...
did you install the apx drivers?
when i hold vol down and i plug usb the APX didn't appear. when i hold vol down + up and plug usb the apx driver appears and i installed it but let me say something
my current version is P999 and in SmartFlash it is saying : version p990
is this a problem ?
the problem is you cant install stuff from a p999 on a p990, tho the phone itself is the same, the partitions are different, if you succeeed in flashing your phone never try that again, at least thru nvflash, as soon as you get your phone going my advice is never flash anything if it isnt with cwm...
as for flashing it, as i told you the same thing happened to me, and i had to flash it from another pc, it wasnt easy tho because i had to insist lots and lots of times auntil i finaly succeeded because the phone wasnt recognised and or failed to flash most times
The info:
Windows 7 64bit
LG P990 stuck at a double LG boot screen. The phone enters download mode (pressing Vol down when plugging USB). Windows finds nothing when pressing Vol Up + Vol Down when connecting to USB.
Tried to NV flash but nothing happens which makes sense since windows don't find anything when double pressing the buttons and connecting it. Am I doing something wrong?
Hello,
Have you ever heard about this useful tool? http://forum.xda-developers.com/showthread.php?t=2020737
Repair your device with it. Also you should have installed all of the USB and APX drivers.
Yes I saw that and downloaded it. But my problem is that the PC doesn;t even find the phone connected. I have installed the drivers. And the phone does find the PC because if I only press down button it goes to download mode.

Use option "Repartition your device....". Follow the instructions.
/*Have you already tried to remove battery before plugging it in to the PC? And while you are plugging it in, you should hold VolDown and VolUp. Screen stays black but PC starts recognizing your device. At least, it works for me.*/
That's my problem...When pressing the buttons and connecting the phone(without battery) the PC (tried 2 systems) finds nothing at all.

I thought i had bricked my device but they did something and gave it to me in 3 to 4 days and that was done under the warranty no extra charge and don't confess that I had rooted ur device , If u tell them that they will try to extort money from u :crying:

Hello there... Any solution you found? I am stuck with my zuk z2 in same situation ?? any help ?
I have a similar problem.
What caused the black screen? -
History:
I booted to test mode at 2.5.033 ST, the phone got stucked at this menue there was no way to get out. TWRP Restore to Nandroid bougt only black screen after 2nd vibration and ZUK logo.
I fixed the Test mode bug, by flashing the ZUI 1.9.104 ST Stock ROM via QPST.
After the phone was "repaired" I unlocked the bootloader, installed TWRP, made a nandroid backup of fully stock ROM and restored a nandroid backup from before the test mode problem.
The nandroid restore was successful, I rebooted the phone and it was "dead". Black screen, only rebooting (perioldy vibrating) there was no end, until the battery was empty.
I got no luck to reach any mode with tricky button pressing (vol+ pwr; vol- pwr; vol+ vol- pwr; usb in vol-) nor Windows detecting the phone. That's why I decided to remove the back glass cover, to got access to the battery.
Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!
Cheers,

What id shown in unknown device.
Like ven_9102&dev_1234
Maybe with editing quallcom drivers for your device id, you can still install it.
and if luck qpst can recognize it as qualcomm debug mod

Alright bro, there is one method you can try.
http://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
I assume your phone is a brick now. The only method you can use is the 9008 unbrick mode. (AKA QBST)
There are a few things you need to prepare before you save ur phone. U need to download the require application that the website provided above, after you set everything up,
make sure you download the latest 2.5 QBST rom,
http://bbs.lenovomobile.cn/z2pro/t554654/
Because ur phone wont be able to enter 9008 through software, thus u need to do the following.
1. Load the content XML fille,
2.Turn off your phone. After it's fully shutdown
3. press and hold the volume up button for 3 seconds
4. press power button while hold the volume up (press it for 0.5second and keep holding it)
5. after 0.5 seconds, plug in the usb right away
6. the QFIL tool should appear the Qualcomm usb QD loader
7. the download button should turn blue
8. flash it and wait for reboot

Thanks for your tip.
I followed your described procedure, but the phone will not be recocnized by the PC.
1st: I loaded QFIL XML file. (By the way this tut is made by me)
2nd: I disconnected the battery (The phone can't be turned off normally!)
3rd, 4th, 5th
6th: nothing happend!
7th: "-"
8th: "-"
The only way the phone will detected by the PC:
1st: disconnect battery
2nd: plug in USB (PC and Phone)
3rd: press VOL+ or VOL- or PWR button (doesn't matter which one)
4th: connect battery
5th: detected as "unknown usb device (device descriptor request failed)"

Yes, I did exactly you described. Sorry but this isn't working.
I don't know what I should do. Even a repair shop couldn't fix it.
Maybe I need to do this:

I will report the result.
OK. I made the deepflash cable.
After using it there is no difference between pressing one of the button combinations I recently mentioned (VOL+ or VOL- or PWR).
The phone will be detected as Unknown device. After intalling my modified driver to match the unknown ID, QFIL don't detect the COM Port.
Hello had the same problem, only with the difference that my battery was not completely discharged.
What has helped:
1 Start QFIL Tool
2 Press the volume +
3 Connect the original cable to the PC
4 QFIL Tool recognized the phone and I could play an original Rome.
Mfg
Ps. Is now the battery cover (glass) broken?
No, I used a hairdryer, a razorblade, plastic tool and a suction cup to lift the backcover glass.
The glass is fully intact no damages.
You have good nerves. I would not have expected that.
But in the end, it does not matter if it does not start anymore.
Thank you again for your great instructions for playing and rooting the mobile phone.
I hope you get your phone back.
Mfg
Good and bad news
The guy unbricked the phone successfully, I received it today.
Now I have an other problem:
The phone is very very slow and laggy now.
The problem occurs everywere, Recovery, boot (the bootlogo laggs), booted System, also the test mode laggs now
Furthermore the sceen flickers sometimes and at the right side the sceen is mirrored sometimes.
Did anyone has an idea?
What I did today:
reflash through qfil
1.9.104_ST
2.3.044_ST
ZUI_2.5.335_ST
Hi m_atze, I am exactly in the same situation as You. After using deep flash cable method, I got "unknown usb device (device descriptor request failed)". Could You tell me what was the solution to unbrick the phone?
Hi,
First i'm sorry for my bad english.
I've a P9, and i tried to update to Nougat. But something went wrong, and now, i can't boot my phone, no recovery no fastboot. When i plug it on my pc, my phone is recognize as "USB SER". How to unbricked ?
Hold volume down + power for 15 seconds, hold it even longer to try to get into fastboot mode. Was the battery low? Maybe you need to charge the phone up.
My phone is charged.
I tried your solution, but didn't work..

Not that I'm aware of sorry ... You are connecting cable to a powered on PC or laptop? Holding down both volume up and volume down whilst connecting cable ?

Also they need to hold the power button
On the newer samsung phones you need to power off your phone hold down volume up and volume down and insert your charging cable in your phone make sure the cable is inserted in a pc or a charger.
