and otherwise i can not even start the phone via power key cuz it doesnt work when phone is off.
but power key works only if it is connected to pc and screen will be open at the same time. but only into charge screen android will not open.
what kind of brick is this? what could i do ?
i have flashtool installed on my laptop.
i checked, phone can be on flash mode via flashtool but i dont even have internet to dowload some OS to flash it. right now.
flashtool's "reboot device into system" key. i tried it does nothing.
actually i may let it sercive even if i will fix this or not.
cuz maybe they will renew it.
its my 12th month of the warranty. so ther is still guarantee.
but once i changed bootloader. to flash some other os
if im not mistaken. i assume it will broke warranty....
any way to change back this setting to fabric default. (bootloader)
does flashtool do it ? i clicked "relock" on flashtool. so its done ?
also i want wipe my phone if it will go to service. how can i
please leave a reply i don't even have internet cuz im on vacation, typing on someones phone

htc touch pro 2 blank screeN

here is my problem guys. i was trying to flash my htc touch 2 sprint it with Raphaelhardspl(wrong flashing) and in the process the screen went blank. i was trying to do it one more time and my PC is asking for qualcomm cdmd technologies msn driver, every time i connect the phone to my PC. i have tried it soft reset. and hard reset wont work. any suggestion will be thanks full. thank you. the main problem is that my pc wont recognize ??
WHOEVER solve my problem will pay 50 buck via paypal
The quickest way to brick your phone is to try to flash it with programs meant for other phones, which it appears you have done.( bricked )
Try putting it into bootloader and flashing stock rom , or try mtty.exe, but if your pc won't recognize it and your screen shows no life, it is probably toast. Does it at least have hardspl on it . ?
yes it does have hardspl. there have to be a way that my pc will recognized it. i think.
As denco7 said, have you tried getting into the bootloader mode?
Hold volume down and press the red button with your stylus.
Connect your pro2 to your PC and if it connects the word 'serial' will change into 'USB'.
If it does, your device is not bricked.
I suggest you flash Hard-SPL again, and make sure to follow the instructions exactly! Don't think you can do it just in a minute, just take your time.
Then flash another ROM by using MTTY (see here) and there you'll get some instructions.
Good luck!
it wont go to boot loader mode, when i connect it to the pc it begin to charge and noting happen , then suddenly the light go off and the pc detect a driver is missing quaccom etc. does any one know about that this driver.
I've had that before... that the MSM technology qualcomm **** is asking for a driver.
There's a driver replacement (used before mtty). You can try to install that; altough I don't think it will help.
If you can't get into bootloader your device is (probably) bricked.
What you can also try is getting your battery, sd-card and simcard out of your phone and leave it for an hour. Then put the battery only back, and try to boot.
Does your phone start when you press the start button? So do you feel a vibrate or somethin like that?
no it wont start but maybe by following that MTTY my pc read it, i will try it. . it doesn even bibrate it just that power light show when that phone its charging thats all.
thanks for you comment guys.
That's strange.
There's one last thing you could try: the ultimate hard-reset
Some time ago I bricked my diamond. I tried all available sofkey combinations.
Then, suddenly, my device vibrated like 3 tiimes very loudly.
It didn't still boot nor go into bootloader.
But after about 4 hours it booted!
I only don't know what the combination was... something like VOl UP + VOL DWN + lOCK BUTTON + RESET.
Just try some combinations, maybe it works for you.maybe not, but you could try it.

[Q] Nexus 5 crashed and wont boot

Hello,
My Nexus 5 is locked, stock 4.4.4 and I never attempted to root or anything.
I ended a call and it got stuck, so I hard turned it off by holding the power button. Since that it wont boot, no matter what I do.
It doesn't respond to holding just the power button, and I managed a couple of times to get into fastboot, but whatever option I chose there it just turned back off. Now I can't get it into fastboot. When it was in fastboot, it was recognized as "Android", and now isn't recognized at all (because it's turned off). It also doesn't respond to charging.
I am desperate, please help me!
Thanks.

Is it charged?
Just plug in the charger for sometime and try to turn it on..
If above fails, you need to get into fastboot and first take backup of your sdcard using this method http://forum.xda-developers.com/showthread.php?p=51694433
If there is no important data on your sdcard, get into stock recovery and factory reset your device from there.
If you can't get into fastboot mode and nothing is accessible, contact Google if you purchased your device from play store or else LG!

The device is charged, it was 90% when it happened. I can't backup it because it isn't recognized as adb device in the cmd.
I managed to get to the fastboot menu again, but if I choose the recovery mode option it just turns off. Is there another way to force reset it to factory settings?

Are the drivers properly installed on your PC?
Had you enabled USB Debugging? (If you remember then good)
If your device is not recognized, then you can't troubleshoot it. If it's recognized, then you can either use this thread http://forum.xda-developers.com/showthread.php?t=2513701
Or get into recovery any how and factory reset.
Just plug in your charger and try again
If above fails, you need to connect Google and RMA your device.

Screen went black

Hi Everyone,
I bought the Honor View 10 and it was delivered to me on 16.08.18. On 17.08.18 all of a sudden while using the phone, the screen went black. The phone is working though as I called from another number and it was ringing. The screen lights up but it is completely black. Since the seller has a replacement policy, I have already raised a complaint and the phone will be replaced. The issue I have is, all my data is on the phone and I am unable to wipe it. I can't do it via adb as it needs to have the USB debugging option enabled on the phone, which I can't enable now. One method I tried was tying to boot into recovery and assuming that I am pressing the correct buttons and wipe it from there. But this is very hard and I am not sure if I achieved anything or not.
This is what I did:-
1. Since the phone is on and currently stuck on lock screen, I need to enter the pin which I can't. So, I keep on pressing the power button until it reboots.
2. Then I press the volume up button and here I think I am booting into recovery. I think I was in recovery because my phone was connected to my pc and it stopped recognizing it. After this I did some button pressings and not sure if anything happened.
If anyone has a method which I can use to wipe my phone, please share. Thanks in advance.

Thanks for the link. I tried it, but since the location on the device was turned off, it is unable to connect to the phone. Here is what more I tried so far:-
I was able to boot into fastboot mode. But none of the commands worked. "fastboot -w", " fastboot erase userdata", "fastboot reboot recovery". My pc is reading the device because when I type " fastboot devices", my device is listed. And the other command that is working is "fastboot reboot".

Another thing you can try, if WiFi is ON on your device, is try to install app to mirror the screen of the phone to your PC, you can do this via PC, open Chrome, log in with same phone's user, get in Play Store and install the app
Sorry but right now I don't remember a good one, but if you search, sure you'll find a good one

Yes location is off on my phone .. I tried that option though but couldn't locate the erase option there .. these were the options:-
1. Ring or Locate
2. Check recent security events for suspicious activity
3. Try calling your phone
4. Sign out on your phone
5. Reach out to your carrier
6. Learn how to take extra steps next time
I tried searching for a mirror app as well. But all the apps I found needed to be opened once on the phone. So, got stuck in that step.
The new replacement phone was ordered today and it might get delivered by Friday. I think I'll visit the service center once before the new phone arrives and this one gets picked up. I though don't think they'll be to erase my phone without replacing the screen. But still I'll give it a shot. Apart from that, if the batter dies and the phone turns off, I'll then try to boot into recovery and wipe from there. Do you know any button combinations which can be used to turn off the phone?

Unable to boot, enter flash mode or enable USB debugging after 'succesful' flash

I use this forums a lot for info but in this case i can't find any leads of whee to go with this, so wondering if someone can chip in some ideas?
I flashed a ROM via flashtool but wasn't happy with it, so i thought i'd just go back to stock and so used flash tool AKA emma to flash one of the options given there.
First attempt to flash it said "flash failed" or something like that and had the "flashing failed, connect to computer" note in the phone when booting it. (I'm sort of making up the terms, not that much into the tech ). Anyway, i tried flashing the same FW again and this time it went through really quick being 'completed' in a few seconds.
Now when i try to boot it gets stuck in the 'Sony' logo. Can go into Fastboot but no Flash Mode (nothing happens using the vol down key), and USB debugging seems to be off now as well.
Emma only works in Flashmode so can't do anything with that. Flashtool doesn't offer anything useful in Fastboot and Xperia Companion recognises the phone when in Fastboot but asks that i unlock the screen and enter MTP...
Any help of where i can go with this?
Thanks
P.s. While keeping buttons pressed randomly it went once into flash mode, but trying to flash a ROM with flashtool it got stuck at "reding device data" and i haven't been able to enter the mode again. Is there an alternative key press combination that i stumbled on by chance? I think i just kept vol up and power held for a while and let go at a random number of phone vibrations
Just tried: Flashed twrp via fastboot and then rebooted into recovery. Same thing. It still opens to Sony splash screen and stays there
Ok, i'm kind of talking to myself here, but mild success and something that might help someone.
Managed to get back in flash mode. Don't know if it's a fluke, unique to this phone, or how it's actually meant to work, but the sequence is:
From the freezed up splash screen, and the USB connected, press and keep pressed power+vol up (hard restart/shutdown)
You get a single vibration, if you let go here it restarts. Keep pressing
You get a triple vibration, if you let go here it shuts down. Keep pressing
You get a single vibration, if you let go here it starts in fastboot. Keep pressing
You get a second single vibration, if you let go here it starts in flash mode.
Possibly a fluke but don't want to have to try again!
Anyway, i managed to flash the last working firmware and it's all good, yet this is the unwanted one. So issue is i still need to downgrade the phone to 7.1.1

Hard brick without fastboot enabled

Hello guys.
I need your help. My phone bricked itself. I left it on charge for the night and faced a black screen issue next day. Bootloader is not unlocked, so I can't enter the fastboot mode. When I press and hold all three buttons I see Mi logo for some time and nothing after. When I connect it to PC via usb it connects after some time but almost instantly disconnects. During that short period of connected state I see usb serial device(COM7) in device manager which disappears then. Then 20-40 sec pause and the same connection and disconnection. Of cource, miflash doesn't see it at all when I try to flash it. I have no experience with disassembling so I cannot flash the phone using motherboard directly or try to enter fastboot by pulling out and in battery. Any thoughts what it can be and how to fix it? Appreciate any helpful info related. I saw a bunch of articles and cases but everything got stuck because of that frequent usb toggling. Not much you can do when you can't even connect

Excuse me, but, there are a lot of errors and misunderstanding in your post, so you should need to sort them out, to can advance on this.
Fastboot doesn't need to be enabled, fastboot is always there, you just need to press the right buttons to send it to this mode.
USB debugging enables the ADB connection, most probably, you don't need it to fix your device.
Although this said, keep in mind that your device must have the bootloader unlocked, in order to use fastboot to flash.
If this is not the case, then you should need to use a different mode, the EDL mode, also called QHUSB-9008.
You can try, firstly, by booting in stock recovery, formatting data, sometimes this may fix the bootloop issue.

Sorry, you are right. I am not good at firmware and all the related stuff. I've updated the post. I was confused about 'fastboot' and 'bootloader'. I meant bootloader was not unlocked. But about EDL - Redmi 6 has MediaTek SoC, but still it has something similar to EDL mode. Anyway, you showed me what I can try to do next. I will try to use preloader like here https://forum.xda-developers.com/t/...icked-redmi-note-9-merlin-hard-brick.4347025/
Thanks a lot!

Ok, I didn't check exactly the processor on Redmi 6, due to lack of time. Anyway, a MediaTek device is even easier to fix (in the paper). Qualcomm's devices have EDL (Emergency DownLoad) mode, and MTK has Download mode (apart from many more modes.)
You also, can follow this guide, with more visual insights https://forum.xda-developers.com/t/...india-6s-using-spflash-tool-for-free.4222027/ of course replace carefully the files from the ones that are for your device.
And this tool also can be useful, to take a complete backup, after to try a thing https://github.com/bkerler/mtkclient
Be advised, that, in any case you have to make a complete format, in SPFT only use the Download option.
Just as a side note, even your bootloader is locked, you always can enter to fastboot mode, the case is that is almost useless, specially in this situation, because a Xiaomi locked device can't be flashed through fastboot.
And to enter to fastboot mode, it's not the three buttons, you have within the various options, as ADB and commands are not available, you can enter manually, either, pressing the volume minus + PWR at same time, or pressing the volume minus button, at same time you connect your device to your PC.
