I have two Xperia Z's , Z1(a) - Display is jet black and sim port broken but phone and touch still function as normal. Bought another broken screen Z1(b) - recovered motherboard to replace Z1a. That worked but now Z1b stuck on pattern screenlock and ebay seller does not want to give me password. I have the old screen with fingerprint smudges and everyday I attempt to crack the pattern lock and phone not blocked as i put sim in and able to call phone and answer..
I have tried connecting Z1b to PC to use Sony Update Service software to restore phone back to factory setting but phone is not recognised or charging by PC (does charge through wall socket and Mac USB port). Run SUS>Press Vol Down Button while connecting USB and LED indicates GREEN then RED but software cannot find phone.
{{Run SUS>Press Vol Up Button while connecting USB and LED indicates solid BLUE LED - not sure what this feature is???}}
So I exchange Z1b motherboard with Z1a and when connected to PC, phone indicates charging and installs a driver to PC. Do a dummy SUS test and phone is found by software allowing option to do a factory reset. Re-exchange back Z1b and still nothing - no charge, not recognised by PC or software - so assume Z1b usb port is faulty.
So read about Android recovery mode but i cannot access recovery mode on either of them - Is recovery mode only available for rooted android phones??? I can only enter safe mode (Power+VolDown) and tried the following options but got no response:
1. Holding Power + VolUp
2. Pressing Vol Up continuously after pressing power button
3. Pressing Vol Down continuously after pressing power button
4. Press all Buttons together.
NEXT STEPS:
1.Connect Z1b to a MacOS 10.6 or later and try SUS and PC companion (i have old Mac 10.4)
Any other help or suggestion??? - many thanks in advance.
Have you installed a recovery?
If not then you cant access something that your phone does not have
You will have to root and install one, just follow the link in my signature to get root on latest KK firmware
PS, wrong section, but I have asked the mods to move it for you
Thanks for your reply.
I thought this was a built in feature on android devices - guess am wrong. I will not be able to install anything if i cannot access phone OS.
Looks like i will have to see if i can reset Z1b through Mac Sony bridge SUS, cough up for USB repair OR by chance crack code.
or just read some "how to" / "Tutorial" / "guides" threads to install recovery. Its very easy.
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 downloaded factory images and flashed the radio, modem, logo, everything. When i did fastboot reboot, the phone went black. Now it wont boot any mode and when connected to PC, Windows reports a malfunctioning USB device

I connected to charger and the led flashed white once. It won't flash again even if I unplug and connect again
EDIT
i connected to computer again. this time the white led flashes on for about 3 seconds then off for 3 etc. Nothing shows up on pc
My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?

Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?
Best whishes,
Joachim

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.

I have changed the cable too(USB flex cable of my lumia and USB cable too), It does charge battery, does keep flashing the start button once in a while when the cable is connected. I am sure USB is working fine. But not getting detected in PC.

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.

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.

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

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?
