Unable to connect to device, since it's stuck in a Bluescreen-Loop (maybe bricked) - Nokia Lumia 920

Hey guys,
last night I woke up, fining my phone constantly rebooting, so I tried to soft-reset it (pressed Volume Down + Power for 10 seconds). After this it booted again, but it was unable to find my SIM card or connect to my WiFi, so I decided to restore a recovery image. Note that I never installed any unofficial ROMs to this device before, everything was working fine so far, so there was no need to do it. It was running on the latest Denim-Update, that was available for the phone.
Since I was unable to recover the phone using the Windows Device Recovery Tool or the Nokia Recovery Tools, I launched up WPInternals 1.2 It showed me the correct (e.g. expected) product number and version (RM-821, 059S0K1). I then downloaded the emergency files and ffu-image from here (lumiafirmware.com/ser/RM-821/guid/059S0K1) (warranty ended about 1 year ago anyway). After rebooting into flash mode, the device started showing a Bluescreen (where only "" gets displayed), right after the Vodafone branding logo.
Since then I am unable to even connect the phone to my PC, nor do anything about it. I tried to follow this tutorial (docs.google.com/document/d/1FdTtfRcR80qnSzjHX1kvTcjMRcoWh8j5hUxw8UM_prE/edit) in order to flash the image directly using thor2. I had to remove the QHSUSB_DLOAD driver from the device manager (note that it was hidden for some reasons). I expected the "Nokia Emergency Connectivity" driver to be installed, but instead only a "NOKIA BOOTMGR" get's displayed.
Everytime I try to connect thor2 to the device, it says "THOR2_ERROR_CONNECTION_NOT_FOUND". I suspect this is a driver issue on my PC.
Do you have any suggestions how I could continue restoring the phone? Or do you think it is lost after all? (which would be sad, because I loved this device. The first one that was as reliable as I expected from it)
Thanks in advance!
I am constantly receiving

Manually invoked flash mode?
Hi, did you try this: switch on pressing the volume-up key? This should display a flash and a cog wheel. In this mode, you can use either thor2 or ImageDesigner to flash the required ffu file.
Refer to https://sysdev.microsoft.com/en-us/Hardware/oem/docs/Phone_Bring-Up/Phone_Image_Designer.
For download search for Lumia_Flash_Tools.zip. It provides 32 and 64 bit versions.

Odin won't detect i9100 in download mode after new kernel

Hi,
So I just purchased a Samsung Galaxy S II, and I've been trying a few different ROM's found on this site. The last thing I did was actually revert back to a stock Samsung Kernel and firmware. This worked fine, but it unrooted my device, which I knew would happen, but now I'm not able to root it again because when I put the device into download mode, ODIN, or better yet, my computer won't detect the device.
I have all the drivers installed, and I also deleted them all, and Kies, and started from scratch again after searching XDA for similar issues.
I don't believe this to be a driver issue, since I was able to root my device, and swap roms before I went back to the official kernel and firmware. I'm with Bell in Canada, so the versions I went back to were not the official Bell versions, since Samsung has not made them available.
I have a Mac, but I've been using Windows 7 and Odin under VMWare. I can connect my device to either OSX, or Windows 7 when the device is not in download mode, and everything works fine, and Odin detects the device (Not that that does any good of course)
When I connect the device under download mode, the Mac detects the device and asks me if I want to connect it to my Mac, or to Windows (As it should) but no matter which one I select, neither OS acknowledges the device after that point, where as when I'm not in Download mode, both OS's detect the device fine.
After all my troubleshooting with my computer based off of what I found online here, The only conclusion I have left is that there is something missing on the device that allows it to be found under download mode, but that aspect of all this is beyond my current skill level.
Anyone have any ideas?
Are you pressing the Volume Up button to continue in Download mode? Besides, Virtual machine isn't recommended I think.
Yes, Once the Custom ROM warning comes up, I press the Volume up button to continue.
That wasn't even necessary on the Stock Bell ROM. The warning didn't come up at all.
VM has been working fine up until now, so I don't think that's the problem, but I have been thinking of trying this on my old laptop that runs on windows if nothing else pans out.

Have you found anyway to Make Odin recognize to phone in download mode?? Im still struggling with that. my phone is on stock kernel and not rooted yet, ODIN finds it fine when the phone is on and USB Debugging is on, but once I put the phone on download mode it wont recognize it, I dont know why..
Could it be because of the ''SAMSUNG Mobile MTP Device'' driver failed to install correctly??
all other drivers are installed correctly.. I have tried to get the driver mentioned above to install correctly but it fails every time, with USB debugging on and off, i have wiped the phone and installed Kies and the drivers several times, Im clueless right.. anyone have any idea please help??
I myself am also suffering from this problem. However, USB seems to function fine while the phone is booted up or in recovery (For ADB). I'm wondering if necessary files may have become corrupted or deleted in reference to USB drivers (phone side mind you) that are used in download mode.
edit: It's also recognized in recovery mode.
Even if it can't be fixed I'd still like to understand why.
-Simply D
was looking for help on this and saw this thread, same problem too..
Connects to Odin and Kies fine when switched on "normally", can use USB mass storage mode Etc.
comes up with a USB device has malfunctioned message on PC when I connect USB cable when switched on and in download mode
EDIT:- just to add, if I try upgrading firmware via Kies it gets to the point where it switches the phone to download mode to upgrade it and has the same issue even with an official upgrade
Figuring download mode is outside the normal boot procedure, I hoped on an off chance that pulling my battery and sim for a few minutes would reset it. It did indeed. Download mode is now functional again, just to be certain I tested it right before pulling the battery to make sure it was still broken. And multiple flashes and reboots afterwards seem to confirm that it has returned to normal.
Anyone else who solves it with this method, please report back.

[Q] Huawei Vision (U8850) bricked

Hello,
I have probably bricked my Huawei Vision by rewriting boot image.
However, I can connect* it to PC and it sees my phone as "Huawei Handset" (same with Windows and Linux). But Windows misses its drivers (non-bricked phone worked); Linux seems to work. No OS can connect to it using default (downloaded) ADB, nor Fastboot, nor SoftwareUpdateTool.
Its PCI ID is 12d1:c002.
How could I reflash it? I would prefer the ways without disassembling the phone.
Thanks
----How to boot the phone, so you can connect it to PC:
1. turn off my phone completely (vol up + power for 10 seconds - release power for a seconds and repeat it once again)
2. prepare USB cable, so you can connect it in few seconds
3. hold vol down + power and after ~1s, connect USB cable (still hold vol down)
4. when Huawei logo appears, release both buttons - your phone is connected now

The thread called 'Problem with huawei vision' still seems to be active. You may want to try asking your question over there.
Huawei (u8850) unbricked
I just wanted to relate my experiences in de-bricking this U8850 phone.
I installed 'Apps_2.6.35.7-perf+root+CWM_recovery 5.0.2.8' (firmware.nb0) using SUT to get CWM, and then installed Danile's 4.1.2
Good as far as it goes, but i could not for the life of me reproduce his kernel (my kernels are always unreliable), so after many days of playing, i decided to take the phone back to stock to see if i could reproduce the huawei stock kernel as a base to work on.
The problem was, how do you revert to stock; the phone was no longer recognised by SUT?
So I took a stock .nbo file and extracted the content (some java extractor found with google) in the hope that I could create a CWM flashable zip of the stock firmware.. a bit of research later, and i thought i had got the gist, put boot.img and system.img into a zip with a modified script file, and voila... a bricked phone.
At this point, i had CWM, but if the phone booted, it showed a flash of blue screen (I didn't know these ran windows ), and back to huawei logo. Also I think i had to dismantle to disconnect battery to run CWM, as it's not available just on the volume-up-power restart.
So then I did more research, and came across QPST, Qualcom's tools. It seemed this should know something about the files i had extracted. I could not correlate everything in the extracted fileset with what QPST seemed to expect, but the first challenge was to get QPST and the phone talking. using various drivers, QPST would sometimes see it, sometimes not, but nothing good seemed to be coming from it. I returned to trying to get SUT to work on my brick; again, with some drivers it would connect, but a flash always resulted in Error 4000 - DEVICE_NOT_CONFIGURED.
Then I read somewhere that someone had found a driver change made SUT work, so i investigated drivers more.
What I found was that if i ran up CWM, I got two Huawei devices in XP for which I could not find drivers.
The devices showed up as VID_12D1&PID_1022&MI_00 and VID_12D1&PID_1022&MI_01.
I took the Huawei USB drivers folder, and copied the qcser.inf then changed entries under [QcomSerialPort] to match my VID/PID values.
(the two that had matching MI_ values).
On driver update, I had a serial port, plus something I'd not seen before - a USB storage device which contained the phone's partitions!!!
This certainly seemed promising... so into SUT again, same error 4000...
So the I tried QPST; and yes, it could see the phone. Scared to do anything to brick it further, I thought, ok, try some memory diagnostics.
On running the 'Memory Debug' tool, as soon as I tried to get a list, QPST said 'this phones in diagnostic mode, it must be in download mode to do memory diagnostics', but even better 'Do you want to set it into download mode now?'!!!!!
Yeah! click the button, and I see a screen I've only seen once before (and i don't know why last time), black, with a line added every few seconds... which from all my reading I know is a good sign.
OK, then I closed all QPST apps, and ran SUT.
This time, the firmware flashed no problem. Was a bit worried as boot time is long (but it was effectively 'first ever' boot for the phone).
I hope this helps someone else with this or another Qualcom based phone.
Basic lesson is:
If you see Error 4000, it may be that the phone is in diagnostic mode rather than download mode.
If you don't have drivers, or don't have the right drivers, check you VID and PID, and try putting them into the .inf file
QPST may have a simple use after all... to force a phone into download mode when SUT fails.

it's actually not difficult to remove the battery...
but i read somewhere the 'volume-up + power for five seconds' will hard restart, but re-press power immediately will then turn it off (not tested myself; the back of mine is already off at the moment.)
Anyone here interested in developing a 3.x kernel? seems other phones with msm8255 have successfully got one...

now i have tried it, and no success.
However, what i have found to work - if your non-boot is actually booting the kernel, but failing to initialise the phone, then you can still use adb with it... I ran adb shell, and then used 'poweroff' to power off my phone, which then meant i could boot into CWM recovery....
i HAVE THE SAME PROBLEME? PLEASE CAN U HELP ME TO SOLVE IT BY GIVING ME DETAILS.
it is working, thank you bro

Kingroot - what a disaster - Blu Studio XL bricked

I made the serious mistake of installing Kingroot which failed installing the first time, then it said try again, then it worked but totally took over every aspect of my phone with no apparent way to delete any of the new "features". It didn't seem to be as much about installing root as it was interested in installing some apps they force you to install which totally takes over your phone. (Side note - it is a shame that this is sold as a rooting software, it should be in reality named a virus or malware and avoided. Too bad for BLU users there doesn't seem to be any other way to attempt a root)
Then installing supersu-me created more havoc, then trying to re-install Kingroot completely locked my phone and put it in a boot loop.
Now upon first attempt, I can't seem to make SP Flash Tool or MTK Droid talk to the phone (first time trying now). I installed all the drivers that came with the forced install .exe (which installs the drivers even when no "unknown device" ever appears in device manager) but I have not yet found any "unknown device" in the Device Manager before or after installing these drivers.
When there is no data cable connected, the recovery menu must be used as the only method to power down the phone because it loops on and on with an attempted power up until the battery runs down. However after using the green on black background recovery menu (hold in VolUp and Power), and making the selection to power down, the phone finally powers down. Unfortunately, as soon as the data cable is inserted into the phone, it begins the boot loop again which makes the laptop ding-dong indicating USB driver loading/unloading over and over.
There are options on the green/black recovery menu to load from SD card and to enable ADB but I can't figure out what driver to use and which option on the green/black recovery to attempt. Of course the factory restore option did nothing and the options for ADB, Fastboot and load from SD card seem promising but all I can find for an image is a RAR file which appears as the format of someone's SP Flash Tool dump, and includes the scatter file MT6582_Android_scatter.txt plus other *.img and *.bin files.
With no way to get into my phone, I don't know how to attempt to load this image which I believe is the extraction from the SP Flash tool. I have installed CDC/ACM driver install package, Google Inc USB, Media Tek usbser from 2011 & 2007, usbvcom and Usbvcom_brom.
Any ideas? Thanks!
Just saying, whenever you root your phone you gotta make sure to have a stock firmware in case of emergencies... It's no one's fault.
hi all,
does anyone have a solution to installing a custom rom on blu studio xl (lte)? the stock rom is on Android 5.1 and its laggy as all hell.
thanks much in advance,
ak
Install mtk v com drivers.
Similar thing happened to me on a mtk phone, I have all software and drivers etc on my home pc, not here. Send me a message tomorrow to remind me and I'll Google drive them and give you a link, with instructions. It can be fixed! Don't panic! I assume you have stock firmware? If not, get that ready and downloaded ready. Also, a few different versions of SPflash tools, some don't work on some phones, even the same phones. And different USB leads also.

Nomu S10 bricked

Hello,
I have Nomu S10 Android smartphone that is currently bricked: OS and data partitions are empty/formatted. I am using SP_Flash version 5.1744 on Windows to try and flash original ROM to it. The problem is as follows: after entering download mode by pressing VolumeUP+WolumeDOWN simultaneously, SP_Flash detects my phone just fine, it tries to download to it, but after a minute or two throws "Timed out" error. Same thing happens if I try to "Readback" or do "Memory Test" using SP_Flash: phone is detected, but then time-out occurs while performing any operation. It looks like phone enters download mode just fine, but then immediatelly freezes and stops responding.
My phone's chipset: MediaTek MTK6737T SoC
It was previously rooted and flashed with ROM taken from identical device branded "ArchOS 50 Saphir" — worked perfectly fine. At the moment it's OS and data partitions are blank.
It still has TWRP recovery on it.
Can anyone offer any suggestions how could I proceed from here? I figure troubleshooting procedure should be identical for any smartphone with same cipset, and there are quite a few devices made using MTK6737T.
Oh, and yes, I did try different computer and different USB cables.

LG k9 (LM-X210WM) impossible bootloader?

So this is a budget phone , spent hours obsessing over rooting it, did the whole process several different times several different ways,
the funny thing is , i can't event brick this device . this runs OREO 8.1 which a chopped down version of the full OREO 8.0 , basically it's designed for budget "entry level phones" . So i'm wondering
why they would make it so unbrickable? is it possible that this device doesn't even have a bootloader? if not why is it so hard to get to it?
Can't access fastboot mode nor the bootloader
One year later and this is still an issue. Here is my situation:
I bought an OTG (on-the-go) cord that allows me to connect a USB stick to my phone in order to extend my storage capabilities, but my phone doesn't natively support OTG (it basically doesn't have the drivers for it). In order to add support for it I need to root my phone, which I am having serious trouble with.
After hours of researching, installing, uninstalling, and factory resetting I've narrowed everything down to not being able to access the bootloader to select the fastboot mode. Here are my phone details:
Device Name: LG K20 (boot screen says "LG k20 Plus" however)
Model: LM-X120WM
Android Version: 9
Build Number: PKQ1.180904.001
Software Version: X120WM11c
As far as configurations go, I have:
- Enabled Developer Support
- Enabled OEM Unlocking
- Enabled USB Debugging
- Made my computer a Trusted Device on the phone
- There are no special "adb" options or configurations within my phone (I saw one website mentioned something about "adb" some options, but I only saw this once, and my phone doesn't have it anyway).
So far I have tried:
1) Holding the Power + Volume Down button for 10 seconds, then releasing the Power button when I see the LG logo, then repress the Power button until I see the "Factory Reset" menu. All this does it give me options to Factory Reset unfortunately (which I've done).
2) Holding Power + Volume Down button for 10 seconds. This simply reboots the phone and does nothing else.
3) I've downloaded, installed (on both my phone and my computer when needed), and tried rooting using the following programs: Dr.Fone, KingoRoot, RootGenius, iRoot, SuperSU Pro, and Superuser. There were some others I tried as well, but I determined I couldn't get anywhere with them specifically because I could not access fastboot mode (one example is "Magisk Manager").
4) Using ADB tools within command prompt (the most commonly recommended method) I tried rebooting the device into fastboot mode using the command "adb fastboot bootloader". The phone simply reboots and that's it, it has not switched into fastboot mode. You can confirm if you are by using the command "fastboot devices", which my device never shows.
5) I have gone to the LG website in order to download the drivers for this phone, however, while I am able to locate my specific device on the LG website, it directs me to download the "LG Mobile Support Tool", rather than download the drivers specifically for this device. I downloaded and installed the LG Mobile Support Tool but when the tool loads it does not recognize my device and tells me I need to install the drivers, which it gives me an option to do. Naturally I start the process to install the drivers but when it gives me the list of phone models mine is not in there *and you cannot proceed without selecting a model*. So, I tried using the closest model to mine (the LMX510WM), but it still didn't work.
6) Because LG does not have a direct download of the drivers for this device specifically I have tried downloading a variety of different drivers for this device. None have resolved the issue, but at this time *I believe* I have the most recent version of the LG drivers available "LGMobileDriver_WHQL_Ver_4.5.0".
7) I've tried adding the USB drivers through any install tools that came with them, and I've tried installing them manually via "Device Manager -> Add Legacy Hardware" and choosing the driver files specifically. This has not resolved the issue.
8) Installed the "wpdmtp.inf" file found within "c:\windows\INF" as recommended for Windows 10 users on one forum or another. Did not resolve the issue.
9) Installed the full Android Studio suite hoping something I was missing would be available, I also tried using the "adb" tools they provided: no love.
10) I also tried powering off the phone, holding the Volume Down button while plugging in the USB cord. This is supposed to do *something*, the instructions says I should enter "download mode", but on my phone does nothing.
11) the XDA-Developers forum suggested installed LGBridge_Setup.exe if I was having problems with drivers, which I have. When I ran the program it wasn't able to connect to my phone.
At this time I've uninstalled almost all software and all extra drivers from my computer (I left only the "LGMobileDriver_WHQL_Ver_4.5.0" drivers), as well as having factory reset the phone.
Everything is ready for another attempt, I've just run out of ideas. Thoughts?
Hi, I have also been trying to root this phone for the last year, but failed.
Everything is exactly the same as your phone regarding Build#, model # etc except i have software version X120WM10c .
The phone always wants to update but then it fails every single time.
I am hoping to root the phone so i can debloat it, and remove the restrictions preventing me from using it the way I want.
Anyone have any advice/info please post here. I will do the same.
Anyone? No response in almost a year.
