Phone boots to black screen. - Huawei P10 Plus Questions & Answers

Hi!
Yesterday I was using navigation on Google maps, when the phone suddenly turned off. Ever since, it only turns on after a long while on the power button with a vibrate. It goes to a black screen for a while and then becomes unresponsive.
I've tried:
- removed sim cards
- charge
- soft reset, hard reset: I can't get into recovery mode
- the device is visible on file explorer, but not accessible: Unable to open MTP device "001,0014"
- mtp-detect: error returned by libusb_claim_interface() = -6LIBMTP PANIC: Unable to initialize device
Unable to open raw device 0
- adb devices -l
List of devices attached
(list is empty)
So, basically a brick that vibrates and shows a black screen. The posts I found didn't solve my problem. It's not under warranty any more (bought in China). If I don't find help here I might send it to the Huawei service center.
Thanks for your input!

HELP - SPV M5000/HTC Uni - is it a brick or not?

Hi All
My Father has an SPV M5000 (HTC Universal). He has unlocked the SIM lock from IMEI number some time ago.
Recently it started going screwy and so he did a soft reset and then it wont turn on at all.
He has let me play with it and if I try a hard reset it comes up with the screen saying "press 0 to restore...", but if you press 0 it says "clearing now" and then appears to switch off. If you press x it also appears to switch off.
You can enter bootloader mode and it displays SERIAL on the screen - when you plug it in to a PC the screen changes to USB. But when I try connecting using MTTY I get no USB port - although selecting COM5 seems to open a command prompt window - but to be honest I dont know where to go from here.
If I try a soft reset it seems to do nothing - although the orange charging light blinks once.
With it connected to a PC in bootloader mode I was able to reflash the ROM and it went through all three stages correctly and indicated it had been successful - but when you finish with a hard reset it appears to turn off.
Before I use it to wedge my living room door open, can anyone offer any advice? I have perused the forum, but cannot find anything which seems to match the fault I am getting.
Thanks in advance

It is possible that the battery had it's day and can't sustain the full on mode. I suggest trying with another fully charged battery.
Thanks Enigma... but it is a new battery and is fully charged - I too have an M5000 and I have swapped the batteries over to check this.
Thanks

Stuck at Omnia7 Logo

Hi,
Omnia 7 had been working fine up until now, steps leading up to the event:
* Debranded registry using chevron tool to install a regedit app.
* received pre nodo update and installed
* Used vpn workaround to install nodo update
* Phone worked fine for a month then when the 'walsh tool' was released I ran that. Went through OK and phone was still useable.
* A few hours later I was browsing the market place and phone rebooted itself and was stuck at the Omnia7 logo. Started phone in USB mode and connected to Zune to restore - got to 34% and errored saying "phone not responding".
* Power cycled again into usb mode and connected to PC but now the device is not recognised at all in Windows (nothing showing in device manager)
* restore mode is disabled but I have ordered a 'jig' tool.
My concern is that if USB mode is no longer picked up in Windows, that restore mode won't be picked up either. I should have the 'jig' in the next day or so.
I had the same problem about a week after I got my Omnia 7 in October last year.
Obviously I hadn’t used any tools for debranding or anything then, It seems like a fault with the phone to begin with, not due to anything you done.
I rang Orange and they sent me a brand new phone the next day. So try ringing your provider.
I tried connecting the phone again tonight and zune picks it up, gets to 99% complete on restore then stops. Seems the USB is being detected again - I did have the battery out of it overnight.
I have the same exact problem but without any jailbreaking
please I you find any solution just tell me
beacuse I don't have warranty I bought it via Ebay
Using the "jig" tool, I was able to enter download mode and reflash the device. I now have a "Welcome to your Samsung Omnia7" screen.
So I can confirm this method works.
Hi
In the Microsoft answer forum someone wrote that the problem was form the battery. So, I will go first with this one.
Regarding the download mode I have problem as well. When I hold pressing the volume up, camera and the power button it display the USB connection logo same as the one in the update. I don't know why!!!

That is because your bootloader does not support the Download Mode and enters the Zune Recovery Mode instead.
Hi! try with this
http://windowsteamblog.com/windows_...spx?utm_source=twitterfeed&utm_medium=twitter
Did you try Hard reset?
1. Press and hold down the Power button + Volume down button + Camera button all at the same time until the device vibrates, then let go of the Power button while continuing to hold down the Volume down button and the Camera button.
2. Shortly you should see the message displaying "Are you sure you want to format?", you can now release the Volume down button + Camera button.
I just formated and same problem appear again and again
I don't what to do
please help
in addition to that I don't have the download mode
You will have to get the jig tool to enter download mode to reflash, or send away for repair.
My phone is still playing up, random crashes then stuck at Omia logo. To get it started again I have to reinsert the battery and even then sometimes it gets stuck at the Windows Phone logo. I will try one more flash and if I still have problems I will be raising a warranty claim.
This happened to my phone this morning. Tried to open Beezz, but it wouldn't start (went right back to home screen).
I obviously tried a reboot, but it got stuck at the Samsung Omnia 7 -screen.
So far I have:
(no difference between the steps)
Installed the samsung update patch\fix
Hard reset
Reflash via download mode to KB2
Hard reset
Reflash via download mode to JK1
No success so far. At the moment I'm letting it stay turned on, and every minute or so it flashes black, but returns to the logo screen.
Any help would be appreciated :d
Mine seems to work for a day or so after a reflash, then starts playing up again. Sometimes stuck at logo until I take the battery out and then put back in. I had a problem opening the messaging app, would get the tile animation then back to homescreen. I have arranged to have my Omnia sent back under warranty so will see what they find.
After a power surge, my Omnia hanged then when I rebooted, its now stuck at that Logo Screen. Did everything possible (hard reset, flash rom, go into recovery mode which gets stuck after zune reboots the phone....)
Used the windows support tool and I get this message: The phone is not in the 'Connect to PC' state. Please, make sure that you follow the instructions and your phone shows the 'Connect To PC' image
Any help would be greatly appreciated
Sounds like you have tried everything I would have already. I would send it for repair / warranty.
Turns out my phone WAS faulty and it has been replaced - should receive replacememnt today (Has taken over a month)

[Q] Stock LG G2 suck in bootloop? Soft bricked? Keeps crashing

FIXED after sending to LG.
Problem: Level3(L3) repair, Damaged Board components without replace any housing.
Cost: $77 which included shipping both ways.
Hello, my ATT D800 LG G2 recently went crazy (not rooted or anything other than factory, it shut down while viewing a text, wouldn't start unless a hard reset was attempted, finally turned on but would shut down minutes later and same above had to be repeated.) Phone is not water damaged or physcially damaged, touch screen works perfect and buttons all work. I was told at a local cell phone shop that the motherboard could be failing but they could not repair/replace.
Log of issues:
-Phone randomly shutdown while using it (black screen with LG logo appeared at shutdown).
-Would not turn back on normally. (black screen LG logo -> off then repeating several times before shutting down.
-Bringing up hard reset then cancelling several times finally booted phone.
-Phone crashed again within minutes and above was repeated several times until phone started.
-Recent apps were deleted, then phone shut down again shortly after
-Phone was rebooted and safe mode was entered, phone still shutdown
-Phone was factory reset (everything erased) but is still hit or miss on how long it tries to boot before crashing again
-Battery was fully charged on of the times it stayed running for a while and still shows a full battery.
-Nothing other than stock rom here, the only thing close to "adventurous" was installing/using greenify since a couple months ago
-Download mode doesn't work
-Tried factory resetting and it crashed while doing it. Eventually did restart for about 30 sec before crashing again.
-Random moments while trying to start- white/silver fuzzy screen, occasional red led blink (didn't catch how many), saying no sim card while it was installed.
Can someone point me in the right direction as how how to fix this myself or which kind of repair shop to do it? Most shops do some hardware but none seem to do the motherboard if that's the issue. I did see a thread where the battery was causing all kinds of problems, but the phone was swollen too, not mine.
Thanks in advance!!!

It might be your battery, u can go to a service center and replace the battery. It may can be your motherboard too, in this case only certified LG service center can help you. If your HDD partitions have corrupted somehow. Which means partial hard brick.
A CSE flash can help here. Steps -
1. Download the desired stock rom for ur device from here[Dont download a wrong firmware] - http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/
2. Download the latest LG driver from the attachment below, install it and reboot ur pc.
3. Download the LG Flash tool from the attachment below and extract it on ur desktop.
4. Turn off ur phone and wait for 2min. Make sure its completely turned off.
5. Hold the vol up button on ur device and plug in a usb cable to connect ur device with ur pc. Hold the vol up button until u see download mode on ur device.
6. Now run LGFlashTool2014.exe[Step 3] on ur pc as admin.
7. Now on the window select CDMA from type & click on the 'folder icon' and add the .kdz file[step 1]
8. Next click CSE flash. A new window should open. Click start.
9. Another window will open, click 'clear phone software update registry'. Then click ok at the bottom[Dont change lang or country]
10. Wait till 100% is done and ur phone boots in.
This may solve ur issue if not then go to nearest service center.
If your device doesn't boot in/stuck in bootloop after flashing do a hard reset -
1. Power off the device and ensure it is not connected to any USB cables.
2. At the same time, press and hold the following keys for 8 seconds:
-Power key
-Volume down key
3. When the LG Logo is displayed, release and then immediately re-hold the Power key.
4. When the 'FACTORY HARD RESET' screen displays, release the keys.
5. Press the Power key to reset or one of the Volume keys to cancel.
6. Press the Power key to confirm the reset. The reset will start immediately.
Thanks for the help, I did manage to get download mode to work one time, the firmware warning popped up but then the screen went black and a ton of network connections popped up. I didn't have time to finish so I turned the phone off (still doing the LG logo thing when I tried to power on and turning back off shortly after. Now it's given me the LG logo once but has become unresponsive. I suppose there's a chance the battery could be dead. I emailed LG for support, i'll see what they say. Thanks for the help!

Does the s7 edge have two GPUS? Always on display works but anything else is blank.

Im having a very strange problem, my screen just stopped working. The only thing that show up is the always on display which works fine in any position on the screen. Ive tried hard resetting it by holding the power and home button, and it does reset but not even the boot logo is shown. Ive also tried entering download mode and the recovery mode but the result is the same ...blank screen. To this point i haven't had any problems with the screen even though the digitizer is cracked. So because the always on display shows up im convinced the screen works, so my next logical conclusion was that my main gpu is fried. Is there a way i could test it without the screen? I know there's a gpu test in the recovery mode menu but i cant read the results.
https: //youtu.be/ jDswDiQAFqY
My device is also not rooted but ive managed to adb connect to it and download my data. And with adb i also have the ability to mirror the screen to my computer but the phone has to be fully turned on and connected to the network so recovery mode is out of the option ...at least to my knowledge.
I would appropriate any suggestions on how to diagnose it and maybe fix the issue.

Xiaomi Mi 9T all of a sudden bricked - ADB shows "unauthorized device"

Hello all,
my Xiaomi 9T bricked - no external force like a drop, I also never tinkered with flashing or something like that - I just heard a notification coming in, wanted to check on that and the phone just never turned on.
I tried getting it into Fastboot or Recovery mode, however no success. What I noticed was, that the phone was kind of recognized when i "booted" it into fastboot. I unfortuntately cant remember, if I turned on USB Debugging (think I did though) and installed ADB drivers to maybe get something done.
Unfortunately, all I get via ADB is "e42a47 unauthorized". Even after killing/starting ADB and deleting adb-files in .android folders. I don't know if my phone wants me to grant access, but since the display is black, I can't tell.
So if you have ANY ideas how to save the phone, I'll gladly try it out.
Thanks!
I decided to try again and google some more. I discovered the "XiaoMiToolV2", tried to install a new ROM. I put the phone (still showing a completely black screen) into Recovery-Mode using Power and Vol+ and selected (blindly) the "reboot" option.
Now the phone seems to work normally, it shows up in Windows Explorer (although not showing files unfortunately - I guess its not in the right mode to do date transfer) and I also can hear the appropiate sounds when charging it/disconnecting it/etc - the screen still stays black.
Any idea where the problem could be? Is this more on the hardware side now?
As already being said, it never went black after a drop or anything (drops did happen in the past though).
e: It seems that the finger-print sensor is still working too.
I am now trying the almost legendary "rubber band"-method to drain the battery and see what happens.
