Not booting Lumia 920 - Nokia Lumia 920

I've got a problem and I just want to know, how bad the situation is.
Yesterday I unlocked the BootLoader via WPInternals. I just wanted to install Windows 10 Mobile 10586, then 14393. After that, insider found 10586 build and I started to download it. I accidently forgot about relocking BootLoader.
When I updated to 10586, I remembered it and thought, that it's going to work. I opened WPInternals and started to relock BootLoader. It was just a second and my phone turned off and now it's not booting. Not reacting, when I connect it to PC, displays as USB Input Device. I tried everything, even instructions with QHUSB_DLOAD but no luck. I just want to know, maybe there are another ways to recover phone.

Hi,
first try a soft reset (Vol- and power till vibration). Then try to unplug your battery (carefully open cover with a T5 Torx screw driver).
Best wishes,
Joachim

Calling all Lumia Experts - Bootloader Mishap

Hi all,
I have a Lumia 710, with an unlocked Qualcomm bootloader. Yesterday accidently while flashing a rom as the NAND Disk Drive, whilst doing that i 'didn't' select the OSBL mode & the one beneath it which says W7 Qualcomm, before flashing it. Now it got flashed but the problem is its stuck to one rom. The App deployement tools gives errors such as 'make sure the phone is booted' even though its booted & fine. Or the other error it gives is 'request rejected by host machine'. When connected to Zune i now get pop up from Zune stating 'we can't create a connection from your phone to the internet' now this comes up all the time. I can sync stuff but can't deploy stuff or flash stuff
When i did try flashing the same rom again. After flashing it started directly at the livetiles screen as if nothing happened. I was expecting the 'Welcome to Lumia' screen. Please tell me whats happening. Also i was able to flash another rom on it. However still Zune gives the same error when connected so does the Deployment Tool. I can't figure out what can be done to solve this. I suppose the bootloader might be affected. How do i refresh it? I thought about going to Dload & then Back to Qualcomm. But it seems that many people have bricked phones trying to goto Dload from Qualcomm.
I want my Lumia to be unlocked, but more over, i want it working fine...
Any help & info is appreciated, Thanks
try going back to DLOAD..or do a hard reset to your phone and flash another Custom ROM again.
wen u connect the phone..open device manager and uninstall the drivers..reconnect in same mode..let the drivers reinstall.

I followed your instructions... Heres what i did...
Step I: Performed a Hard Reset using the Vol Dwn + Camera + Power Up keys.
Step II: Turned the Phone off & connected the phone with Vol Up + Usb connect. Theres an asterisk sign on Qualcomm CDMA Technologies MSM (I had it uninstalled prior to the reset using the Device Manager, It was detected whilst i connected it in Nand mode again)
Step III: Flashed a new rom on it. Lumiatrix v4.3. Still Zune is giving the same error & Application Deployment is not yet possible.
Surya there are three things i need to ask you.
1. In your Noob Guide the rom flash part you are asking people to turn On their phone, select Nokia Connectivity Mode & then select the .nb file & click Write Os. When i try that it asks me for a Nand Drive.
2. If i should try going back to Dload (can i switch to Qualcomm whenever i feel like?), can you please suggest me a clear & concise method, as to how to do it. I wanted to try this (http://forum.xda-developers.com/showthread.php?t=1702815) but its too confusing.
3. Is a bootloader refresh possible? I connected my phone when it was On. I got the Nokia Connectivity Mode. I tried installing the bootloader it found the phone but wanted me to be in the flash mode. However, when i enter the Nand mode it never finds my phone except when i Write Os on it.
I know i have a long list of questions. Its only because of the fact that i want to understand this better. I dun wanna end up bricking my phone. Thanks in Advance. Tc & Godbless!
Ok..wen u connect your phone to the PC while its ON, its in normal mode...the moment u turn on NSS, it will change modes, so it doesnt matter unless u click WRITE OS, which switches the phone OFF and puts it in the NAND dDrive.
as you have a 710, you can try going back to DLOAD and flash a Stock rom and see if that works, and then you can always go back to a qualcomm by my guide.
your at no loss , unless the problem you have a more complicated than we think it is.

Are you suggesting using NSS Bootloader Restore? If so, is there a mode that i need to be in? I'm using NSS 0.51b & when I click on restore it brings up a very scary warning message. As I don't want to brick it, i haven't used it yet.
Please suggest me a method... to return to Dload

[Q] Stock Recovery shows error while rooting

Hello friends,
This is my first question and I really need help with this one. I am not a developer but trying to learn a few things to keep up. I have an HTC Desire X which went crazy after a jelly bean update and hence I decided to do something about it. I heard about rooting and flashing phone from my boyfriend and hence I got brave and read about rooting from this forum...but really messed things up.
I tried rooting Desire X running android jelly bean using Desire_X_All-In-One_Kit_v2.0 by hasson2000. I got really excited and messed thing up. Instead of following the correct procedure, I actually tried flashing a ClockWorkMod recovery without unlocking the phone. During the flashing process, I got the Fastboot menu on my phone and so I cancelled the first command line on my PC screen. The second screen appeared but after waiting for a long time nothing happened so I got scared and removed my USB cable form the phone. Then I tried the exact procedure given in this forum. But when I did, instead of booting into the Fastboot menu, phone shows a red triangle with an '!' symbol.
I can boot into the Fastboot menu by pressing Power and Volume Down button but then my computer doesn't recognize my phone.
Please help...this phone is my life..:crying:
Before you do anything further, do you have HTC USB Drivers installed on your PC ?
Your PC running Windows 8 and below ? And is your PC has USB 2.0 ?
The screen that you show is the screen before you go to stock recovery.
You said your JB update not working right, have you try to factory reset your device after you do the update ?
Before you can do rooting and flashing ROMs, you need to unlock the bootloader first. Unlocking bootloader will make your warranty void and null. So make your decision whether you want to proceed with bootloader unlocking.
I strongly recommend not to use a toolkit but to do it yourself. You don't have exact control about what the toolkit does, also you'll learn more about the process that way. Some important things to mention further: If you decide to unlock your bootloader, do it via the www.htcdev.com site. There, you'll need a login first, after that you can proceed with the steps given to you by the site. As ckpv5 said, you need to be sure to have all the drivers installed correctly (or use a linux live cd instead). Then, after you have installed a custom recovery, take a backup of the stock firmware first before you start to change anything! That's really important, otherwise you won't be able to get back to stock anymore. Good luck!

Thank you. You guys are so quick and helpful.
Yes I did install all the drivers of HTC but still my PC wont recognise my device when in I use power button and volume down key to boot into fastboot. My computer runs on Windows 8. I have the USB drivers installed and I have also tried a factory reset of my phone but nothing works! I think what I did made something bad happen to phone recovery.
Please help
Did you read everything and tried it as we said? Do you use USB 2.0 instead of USB 3.0? DO you have the bootloader unlocked? Please answer these questions first, otherwise we can't help you much.

No. Like I said, I got excited and messed ip the steps. Instead of unlocking the phone I first tried to flash a ClockWorkMod recovery. While doing so., it tool a lot of time after showing the fastboot screen so I thought something was wrong so I disconnected the USB cable. Then I realised that I had to first unlock it so when I tried to unlock the device, instead of showing the fastboot screen my phone shows the screen whose picture I have posted in my earlier firts post. I use usb 2.0.
Please help
Hoy did you unlock? Did you register at htcdev.com for a key? Did you submit the identifier token? Try the exact procedure given here: http://forum.xda-developers.com/showthread.php?t=2076675 and read everything. also the external links, to be sure to understand what you're doing. Then, do it without using a toolkit.

P780 Bricked and not recognized in PC

Hello,
I bought a Lenovo P780 some days ago from china.
The phone came with many pre-installed Chinese apps that simply annoyed me, moreover I kept getting email has stopped, settings has stopped error messages. It was running on a VIBE firmware.
I checked online on how to Flash the phone to international version and downloaded some ROMs to do the flashing.
I managed to get the Flashing done, with this ROM, P780_ROW_S110_130629, but afterwards the Phone was completely unusable.
The problems are as follows,
1. The Phone does not boot up at all after pressing the power key, nothing on screen!
2. Pressing the power and volume keys shows nothing!
3. when plugged to the computer, i get the USB device not recognized error message! (I have all the necessary drivers installed)
The computer only see the phone as follows, Alcatel Single RNDIS Interface in the USB Device not Recognized window.
4. The computer keeps playing the plugged in devices sounds, plugged sound the followed by unplugged sound, repeatedly, and that is when the phone is still connected.
It´s only later I found some tip saying that one cannot flash a device produced 03.2014 and later with the ROM I used. Mine happens to be such a device Prod. Date 09.03.2014!
I have read through some almost similar problems but have not encountered my specific problem.
I am hoping to have someone who knows a workaround share with me how to get the phone back up running. I will highly appreciate your Help.
Solution Found!
Found solution :laugh:
1. Restored the comp to 3 days ago, before installation of any drivers
2. Downloaded and installed this driver, http://www.mediafire.com/download/lbdo0sglhdhrje9/MTK+Divers.rar
3. Downloaded my ROM here, used this one, P780_S123_ROW_131231
http://www.needrom.com/mobile/lenovo-p780-2/
4. I downloaded a newer version of Flashtools from this forum,
5. I downloaded this preloader,
http://forum.xda-developers.com/attachment.php?attachmentid=2744499&d=1400125492
6. I prepared the files for flashing as usual, (USB speed set to „do not switch speed“), changed the preloader´s location to the one I downloaded, (Trying to flash with the one in the ROM gave an error)
7. I removed the Phone´s back cover, plugged the usb cable to the phone, and holding down the reset button, connected the usb cable to the computer
8. Then released the reset buton and VOILA!, the flashing began :fingers-crossed: and ran without any errors.:laugh:
9. The greatest moment was to see the phone reboot fully after this. :victory:
After rebooting and connecting to the internet, I upgraded the FW and everything is running smooth.
I liked the preinstalled VIBE ROM, only that it had some flows here n there, plus the preinstalled Chinese apps annoyed me! I am now getting used to the original P780´s ROM.
Anyone who lands in my previous mess,- Flashing with wrong ROM and cannot get Phone to boot up, or get it recognized by PC, can try out my solution, of-course at YOUR OWN RISK!
PS, Always take time to inform yourself fully before performing this task, it will save you some Headaches!

So you can confirm that the P780_S123_ROW_131231 version works on a Chinese model ?
No problems with bad signal, SIM not detected and so on ? I'm trying to figure out if it is safe to go ROW.
And as I see your steps, it would also be an option to remove the drivers again I think.
For me, it worked by simply plugging the device into a different port, and then I could install the drivers (as a regular Mediatek USB device, not as the Preloader device).
......confirm?.......

I can confirm with my device, I bought it directly from China and as I mentioned earlier, it had several Chinese apps that really annoyed me. I was really stressed up trying to configure what to do. But after reading several forums and stitching the different opinions together, I managed to do what I did earlier on today and everything is working out fine.
I had not done any backup of IMEI and co before flashing my phone yesterday, and that worried me the more. But after re-flashing it with the above ROM, everything got back together and even the IMEI was found automatically without further hustles.
Please do some more reading before trying my steps, my tryout worked good with my Phone, cannot tell whether it will with yours!
Saying this coz am not really sure whether the date written at the bottom of the Accu. represents the phone´s production date!

Well pretty sure the unbricking works, you got the preloader from my post
I'm now testing with VIBE 1.5 (KitKat), pretty good (almost not Chinese there) but some battery issues. Next step is to find out if I can get the 3G 900Mhz band to work.
Not sure if I'm going to switch to ROW, don't see any reason now.
Thanks for the feedback!

Sure it worked out just fine. Didn´t notice you were the same person with almost the same problem in the post with the preloader.
I will be checking out this pages to see how the Kitkat versin goes. Am am curious just how it will be.
Have a great week!
Thank you, you saved me!
I have bricked my lenovo p780 while trying to change the rom.
It was shipped from china with Vibe rom, I tried to install S113 rom and the phone went dead.
I have followed your guide and it worked. The phone is working!!!!
Edit: Just to add some more details in case some one else is having the same issue.
I made it with windows 8.1, drivers from this post, and S123 Row rom.
Then the firmware had 5 or 6 updates to 4.4.2 Kit Kat.
I have 2 more to go.... Total of 3 phones. Will update if any changes are found.
Also I will keep the software in case some of the links does not work or the code can't be found.
i dont understand the part where you hold the reset button and release it.

help flashing not starting and plugin out sound is coming
I know this is a very old thread, but, I was fixing up a P780 for a friend (he was constantly getting gapps.com stopped working and such) so I flashed some (stock?, Lenovo_P780_S115_MT6589_20130807) rom I found via SP Flash tool. It worked fine. So the next thing I was supposed to do was write IMEIs back, and for the life of me, i couldn't get that to work ( i would always get to "start searching kernel com port and handshake", and after that would get something like enter AP meta mode fail default, or something like that) so I started looking for alternatives, and found that one of the easiest ways is to root the phone, and install mobile uncle or MTK tools or whatever, anyway, I download twrp, flashed it using SP Flash Tool, and now the phone won't turn on, can't be detected by the Flash tool, it is in a way detected by windows (Unknown USB Device, Device descriptor Request failed), although it sort of goes on an off. LED lights up when connected to a charger or PC via USB

[Q] Neo V Hard bricked, no led, no boot, no vibrate and help pls

Hello everyone in the XDA community, my very first post and my first bricked phone :/
i've been trying in my spare time to unlock my neo v/ MT11i sim-carrier locked and bootloader 'no' with 11W46 but with no luck. Tried s1tool for identification on the bootloader via testpoint and successfully installed semc driver/ zeus flash driver however patching semc it failed qcReceivePacket: can't get packet data. then i found the zero% fix tool method but then thats when it died. before running the method i held the 'menu' button and inserted the usb.....
a 'sony control driver' poped up and my pc crashing and restarted. No led, no vibrate, no boot. and no detection by the pc. I've read across the forums such as charging the battery over 24 hours and putting it in flashboot mode but the phone still didn't respond-dead brick. read about trim area damaged and jtag box is the only way to rebuild the damaged bootloader but these were cases where people flashed roms, so i couldn't directly compare if this was the cause of the brick. contacted Alejandrissimo a few days ago for some advice with my bricked phone but no reply yet. bought a spare ba700 battery from ebay and tried troubleshooting with it, low battery red flash did come on when i tried to turn on but still no response with booting, vibrations and led. afterwards charging the new battery, it acted the same way as before.
The only way the pc detected the phone was reusing the semc identification method via testpoint. plug the test point cable and pointed it to the 2nd gold plate away from the battery and on the side closest to the micro sd reader and plug the usb port however in device manager the zeus flash driver had a yellow attention triangle meaning not the correct driver or something. so i reinstalled it but no change and tried removing it and only showed qhusb load. Running s1tool and flashtool i tried to get the neo recognised but with no luck i was unable. eg. holding back button for 15+ seconds.
i'm still a novice to android and really appreciate any help possible.

Thank you kks11 for fixing the whole Trim-area and guiding me how to flash new firmware. Even if it seemed hopeless to fix a dead brick, he knows his stuff and was able to fix my neo. I recommend anyone who has a Hard-Bricked device, go ask kks11 for advice and unbricking.
good service, willing to help and one awesome guy.

Hi there, I have a problem. I flashed a ROM and i guess it also flashed a kernel, while im on a locked bootloader... uh oh. The phone can still charge the battery and I get to the SONY logo but nothing after that.
I have tried plugging in a USB cable with VOL - but then windows tells me it cannot recognize the device. I have installed the flashtool drivers and PC companion drivers but no go. Any help would be appreciated.

Here is a recovery guide
I have tried this method. My problem happens when connecting the device after setting up flashtool. Windows tells me the device could not be recognized (device descriptor request failed), the phone flashes a red led when i plug in the USB cable and then green for a split second right after. then blank nothing, and the error shows up on my desktop.

Here is everything you need
I have done all of these steps now and still have the same issue. The drivers installed with no problem when I enabled test signing, but the phone still will not recognize on my computer.

(yay college. Teacher is wondering why im staring at the floor )
Bump. I have a dead phone here, I've tried another computer and I am still getting these errors. I might have to replace the mainboard
we need more info to understand what happened and possible fix... what rom where you using before flash? lb or ub? what rom and kernel did you try to install and how?

It's hard to remember, my phone was in for repair for an entire month, but because of one chip on the back plate they deemed the issue a physical problem and didn't cover it under warranty.
I think I was trying to flash back to eXistenz but I believe I flashed a kernel by accident, slip of the hand I guess. I went to restart the phone and it became frozen on the SONY logo. The phone is LB. I just need a fix!

i think Envious_Data is right, flashing a stock .ftf with flashtool should fix your problems as flashing wrong kernel shouldn't hard-brick your phone, only soft-brick.
But since you can't get your phone properly recognized on the pc you either have a bricked motherboard (i don't think that's the case) or you are having driver issues on the pc (most likely). maybe try flashing on windows xp?
I agree with the above
