Bricked device : Black screen and white notification LED - OnePlus 6 Questions & Answers

Hi,
SITUATION : I just had a big problem with my OP6. First of all, I was on Oreo stock Rom and I decided to upgrade to Pie by flashing .zip via TWRP. Everything goes well, but after some days of use and for some reasons I wanted to roll-back to Oreo and I flashed the downgrade .zip but this time via Local upgrade. Again, everything goes well but when trying to flash TWRP via Fastboot, I used "fastboot boot TWRP.img" and phone booted into it. Then, BEFORE flashing the TWRP.zip file I accidentally changed the slot (b to a) and rebooted to system.
PROBLEM : Now, the device is stucked on a black screen with withe notification LED on, and whatever the situation. Bootloader isn't accessible anymore. None of the buttons combination work properly. I don't know what to do. I looked for MSM software but do I need to access Bootloader to use it ? It's possible to power off the device (white LED turn off), but nothing more.
Thanks for any future advices

power off ur device !!!
open msm software and connect ur phone through usb and press up volume + power button and u will see it getting connected to the msm software and leave it till ur phone starts booting ito OOS 5.1.5

I hope u fixed it by now, but if you still haven't fixed it yet, you can go back to slot b by using this commands "fastboot --set-active=B" without the quotes
Because I messed up my slot a, so i used that command to boot using slot b and it worked. So, if the problem is with your slot a and everything with your slot b is fine, then you just need to change to slot b with that command and all should go well :highfive:
just noticed that you're having a problem accessing the bootloader. First, make sure your device is not connected to your pc or anything. Then, whether your device is off or stuck in that black screen, just hold vol up and power off at the same time and wait until it eventually boots into the bootloader mode.

Problem solved with MSM software. Thanks everyone. If someone has the same issue. Just download MSM software and use the following guide :
https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012
It is actually quite impossible to totally hardbrick a device like this one.
Cheers

Glad to hear that.
Just in case i got into that problem, could you lead me to the files you downloaded since the ones in that link seem to be for OnePlus 5

In my situation, I have a black screen, and a fixed blue LED.
I want to put the LineageOS ROM, but it's impossible, even though it performs the installation of the ROM correctly, when you restart it that happens, and then it doesn't even let you install or start the TWRP again.
It only remains to use MSMDownloadTool, to return to the Stock rom.

Phone will only enter Fastboot, cannot get phone into Flashmode to unbrick

Let me start off by saying that I just got this phone and decided to install a custom recovery and rom on it. As I do with all my phones that allow me to do so. I got the phone with android 4.4.4 on it, rooted it with Kingroot, and proceeded to use the XZDualrecovery tool to install TWRP. After that was all done, I downloaded the Z5 Expierience Rom, and I'm going to take a long shot here and say that I must have majorly missed something. Because after flashing that Rom in TWRP, my phone will do next to nothing. All went fine with the install of the ROM itself. Wiped Dalvik/Cache before restart.
If i hold down the power button I get a single vibration and then the phone does nothing (Does not even turn on backlight). If I plug the phone into my computer the phone will start a sequence of Red (LED), Green (LED), Vibrate. It does this aobut once every second. I can access Fastboot if I hold the volume + button, the LED then goes solid blue and the phone stops the LED - Vibration sequence. The only problem I have, as far as just not being able to Flashtool it back to life is, not being able to get the phone to go into Flashmode. No matter what I do, the phone will not let me get it into Flashmode. Im sure there is a good reason for this, I am just not sure what it is.
I've been flashing Roms and Recoveries since G1 days. I'm usually pretty decent at figuring this kind of thing out, but this thing has got me puzzled. I clearly went terribly wrong somewhere here, hopefully someone who knows this phone much better than I can point me in the right direction and hopefully get my less than 10 hour phone working again.
P.S. - If the phone is plugged into the wallcharger is does something similar to when it is plugged into my computer, but instead of a Sequence of Red - Green - Vibrate, I just get a steady red blink folled by a vibration. The phone will continue to do so until unplugged from the charger.
All help is very appreaciated!
I'm having the same issue. Anyone with the fix would be appreciated
Not sure what to try at this point!
I've been looking non-stop in my free time for a fix for this thing, and no matter what I do I keep getting the same results. Not really sure where to go from here, I have tried Flashtool, Emma, and PC Compainion out of desperaity. I tried all three options on teo seperate computers (One Windows 10 and the other Windows 7.) I have also tried multiple cables. No matter what I do all this thing will do is blink at me and vibrate. Is this thing hard bricked? I read its close to impossible to hard brick one of these phones. I'm wiling to accept that I have if that is the case. Just would like an opinion from someone who has some knowledge with these.
Same here, someone plz help.
If is only a change of batery or the phone is dead completly, an the stop trying to revive it.
Thanks .

!st question is did you flash the correct rom for your device?
If you can go to recovery, then try to flash another rom,
Or use adb/fastboot to try and flash recovery img and use fastboot to reboot recovery.
Alternatively you may have to flash a kernel relevant to your rom.

Try this and see if it helps.........
If your phone is unbranded, i.e. not locked to a carrier, download a any generic(customized) firmware for your device through Xperifirm and flash it through Flashtool. It will wipe all your data (excluding your microSD, of course) but you don't have any other choice. This is most probably unbrick it...... So, try it and all the best.:good:
EDIT: If you've tried it, then go for this. Luckily you've fastboot still working, right? So, go to fastboot mode and flash a recovery image through it. It may take a lot of time but if recovery works, you can install a stock based rom for your device and then go back to stock firmware through Xperifirm and Flashtool.....
The phone is a Verizon model. I've tried to unlock the bootloader using command prompt following the sony instructions, after recieving my unlock key. I am able to connect to the phone and all of the fastboot commands work until I try and run the one to actually unlock the bootlaoder. That says the it is "not allowed." I think that is because I never enabled OEM Unlocking in the developers menu though. Not sure if there is a stock kernel I should try an flash through fastboot. Or if there is a stock recovery file that is flashbable through fastboot with a locked bootloader. The phone is definetley working in fastboot and somehow still knows how to charge. Im pretty sure at this point the problem is that the phone has a custom rom on it but the bootloader is still locked. I cannot unlock the bootloader because I can't get in Android to enable the proper options. Have also tried Flashtool for unlock the bootloader, along with extracting kernel sins from a stock 4.4.4 and a stock 5.0.1 FTF and trying to flash them. Since the begining I have still seen no change in the phone behavior.

dude I'm from the Verizon side yea like you have an bootloader status unlock no so your not going to change that and you can only flash Verizon z3v stuff you are really lucky if you can still get to fastboot after doing this. Use flashtool and flash a Verizon ROM from the z3v section only and pray it works.

Cannot enter fastboot, no system installed, phone soft bricked

Background: Rooted phone with SuperSU and TWRP. I am very unknowledgeable when it comes to everything programming wise.
Yesterday SuperSU got an update. I installed it like I have before, and rebooted. My phone got stuck in a boot loop, in that it would go past the Sony screen and into the animation, but then reboot. I still had access to TWRP, so I tried doing some reading and attempted to flash a new ftf onto my phone using Flashtool. It didn't work, and now my phone was stuck at the screen that says Sony and Xperia. Next I tried using fastboot to flash boot.img and system.img onto my phone. It worked and my phone booted into a very generic looking OS. However next I tried flashing an updated tft onto it - This caused it to not boot at all, and instead get stuck on a screen that shows only Sony. I was able to use fastboot to push a TWRP image onto my phone, so now I can (occasionally) enter TWRP. However, despite pushing version 3.0.2.0 onto it, it says it has version 2.7.2 installed, meaning I cannot install image files from within the recovery. I cannot enter fastboot either, as when I try to it just gets stuck on the Sony screen again. I'm currently charging the phone, as I believe this might be the issue, but if anything has any idea what I should do, please help. I've read about flashing a system.sin file, however when I can't actually get fastboot working, no solutions seem tenable to me.
Like I said, I'm pretty much illiterate in this area, so don't go too fast on me please.
One more thing I should mention, when plugged in my phone will enter the Sony screen and get quite hot, even if I turn it off by holding in the power and volume up buttons, so I'm fearing it's not even charging.
You need to hold power on and volume up buttons together until phone completely turns off.
Get a firmware and put it in flashtool firmware folder ("C:\Users\XXXYOURNAMEXXX\.flashTool\firmwares") use a sony usb cable and hold the volume down before and whilst inserting the cable when prompted on flashtool.

I did that, trying to flash a new firmware to try and fix the boot loop is what made the problem worse. After I tried that the phone wouldn't go past the Sony screen.
EDIT: I think I'm making progress. I had made the mistake of downloading firmware for Xperia Z3 compact. After getting the correct firmware, the phone has now booted and is showing the android robot as during a firmware update.
Thought I'd add that I got my phone working again. Turns out I had been trying to put a Z3 compact firmware onto it. found the right firmware, flashed it with flashtool and it's working just fine now. Might be a good idea to keep the thread open for others who are doing the same mistake?

OnePlus One Revive? Anyone can rack their brains on this?

So I got this Oneplus one from my friend and it's come to me to revive it as there is something wrong with it.. The current state of the phone is that when it's plugged on the computer it can go into fastboot mode or when I try to boot it I will see the oneplus one logo and then it will bootloop. No recovery mode. For some reason without plugging in the phone when I try to start it the phone just vibrates and then goes off and the screen is black all the time. Have charged the phone for an hour to make sure it's not out of juice.
This phone has unlocked bootloader and was on Lineage OS if I am not wrong but I am sure this friend has done something wrong in flashing the wrong file. I know there are loads of solutions which I have tried. Trust me I've tried all and then I am making this new thread or else I won't replicate content.
Things that I tried :
1. Tried flashing cm-13.1.2-ZNH2KAS3P0-bacon-signed-fastboot_64GB via fastboot mode. Everything writes properly but still the same bootlooping and no recovery.
2. Tried flashing Color OS via MSM8974DownloadTool. Everything again goes fine and it's green but again got the Red oneplus one logo this time (maybe that's the color OS boot image) and then bootlooping. Also no fastboot in this mode.
3. Tried Oneplus One Patch released by them officially on their forum to revert the phone to complete stock. Again same issue.
Is there anything else I need to try to make this phone work or is this going to the bin
Any leads would be appreciated from you guys.
Thanks.
have you tried swapping out the micro usb cable because that might be your problem
Replace the batteries with a new one....
Try using fastboot image of cm11s, the very first factory rom for bacon.
I once had to go this far back when flashing sail rom or something
OK let me try with a new cable and let me try flashing cm11. Will update. Thanks.
Update : Trying since morning to get the CM11 fastboot file but unable to get it. It's there on android host server but I am getting constant speed of 10KB/s. Kept it to download for 6 hours and it failed to download.
Anyone has a google drive link to the file? It would be a great help.
If fastboot works there shouldn't be problems at all. First of all wipe everything including internal(search commands online)...also try "fastboot oem unlock" command again. Then just simply flash the latest TWRP via fastboot and from TWRP flash Official LOS15.1(works beautifully) and gapps.
i had somthing simular happened and what i did was i flashed color os then flashed twrp then cm and then booted it (it worked) then flash linage os 15.1 and thats that (i did this cuz i bricked mine while trying to make a boot logo)and btw make sure you have not got the color os boot logo set as the boot logo while installing other roms due to the fact color os boot logo stops or roms from loading make sure you have got the original boot logo!

who are you downloading it from aka which developer
I am inside the OS so the issue was to do with the cable. So stupid but I guess flashing Color OS did help. Thanks a lot guys. We can close this thread. Also the battery seems to be broken, will have to change that.
because i had the same issue a few months back i totally bricked my opo and i thought my phone was gone and not coming back

Phone does not boot/Screen blacks out.

So I have a recent issue that I have not seemed to resolve. Today, under normal use, my pixel's screen went black and I have not been able to power it back on. I was using the pixel dust rom when the issue happened. I have booted into twrp and tried to factory reset but the screen even went black during the wipe. After that, I booted into the bootloader and attempted to flash google's factory image. The phone actually stays on during the bootloader session. It seemed that I was able to flash the factory rom but once I tried to reboot, the same thing happens. The boot animation will play but that's as far as it gets until the screen goes black once again.
If anyone has had this issue or if anyone has an idea on how to resolve this issue, please respond quickly.
Much Appreciated!
After the screen goes black, are you still able to communicate with the device over adb/fastboot? Have you tried reflashing the factory image (make sure the checksum is correct!)? If you put the phone in the refrigerator for a bit, will it last longer before going black (i.e., bad solder)?

So during fastboot, the screen actually doesn't go black. I am still able to remain communication and That is when I tried flashing the factory image. How do you make sure that the checksum is correct? I didn't receive any errors during the flash indicating that it didn't flash properly.
If you're using Windows, Hashtab is a good, free checksum program with a GUI.
Download
Info/Review
On Google's image download page, copy the SHA-256 listed, and compare it to what you have locally (which you used to flash onto your phone).
how to boot into twrp? almost the same issue to you, adb cant find my phone.

If adb cant detect your phone, it looks like the only way that you're going to boot into twrp is through the bootloader mode (if you had it previously installed). Holding down volume down and power will get you into bootloader and then using the volume buttons, you can cycle through the options until you find "recovery". Pressing the power button will select that option.

It looks like your freezer method works. Putting it in the freezer actually gets the phone to boot completely into google's factory image. its usuable for about a minute until the problem of freezing and turning off reoccurs. It feels like the phone warms up while running so maybe i have a hardware problem rather than software.
I seem to have the exact same problem with my pixel 32gb, my device was not rooted, nor did I had any custom recovery but the bootloader was unlocked. The issue happened one day while I was browsing the device went black right infront of me. It was not like I did a dirty flash/mod or something. I'm able to detect my pixel via fastboot, able to flash the factory image no problem, but does not boot up after successful completion of the flashing, it just goes black after "google" logo. Anyone found a solution yet??
thank you sir, I have twrp installed previously. but the screen doesnt turn on so I can't choose the recovery model. and try to hold the power button for a while the phone will become warm. no other response:crying:

Maybe try locking the bootloader? I might try to do that since you and i both are experiencing the same problem with an unlocked bootloader. But i can't see why that would impact anything.

Phone won't turn on, no system

I have a xiaomi redmi note 7 pro from china and I was planning on rooting it and changing the rom. Anyways I unlocked boot loader and installed twrp but couldn't install the rom using twrp recovery mode. Then I followed a video which rebooted the phone into recovery mode again after clearing some things. However, before rebooting it says no OS but the video did it anyways. In the video the phone rebooted back into recovery mode fine, but my phone does not boot. It constantly boots up to the redmi logo, flashes and boots again into redmi logo. This continues forever. I can, however, at this point enter fast boot. I thought the problem must be I have no rom so I just need to flash a rom. Using mi flash tool didn't work there was always some error and I turned the phone off. After turning the phone off, I cannot turn it back on again!!! Nothing, not holding power, not holding power + volume, just pure blank can't boot at all. I really don't know wtf I can do know it just doesn't turn on at all no matter what. Please help guys.

1. Never boot into the system when there is a 'no OS' warning.
2. Use this TWRP next time (https://forum.xda-developers.com/redmi-note-7-pro/development/unofficial-twrp-3-3-1-proper-t3933531)
Does the phone charge or get detected by the computer when connected via USB?
If MiFlash doesn't seem to work try using ADB to Fastboot the ROM
If all hope is lost, the service centres can fix it.

when connected it is detected as qualcom 9008. I searched I think the phone is hardbricked, so can't enter fastboot. I think it can turn on and off. After holding power for 15 seconds, the usb is no longer detected. I could do the same to turn it back on. Do you know a service centre in Toronto?

Yes it's hardbricked for sure! But are you sure MiFlash doesn't detect it?
If so any good service centre around you should be able to fix it, it's something to do with the software so they won't need Mi authorised parts...

Mi flash detects it as COM10 or COM20 depending on which USB. But when I flash I get error like no hello packet. Also I am not sure if I am suppose to put prog emmc sdm660 in the images folder or not.

Ok so Hello Packet errors are caused due to corrupted files or also if your flashing is interrupted in the middle
Try:
1. Making sure your PC isn't 32 bit
2. Draining out the phone battery and try again
3. Disabling driver signature enforcement(https://www.androidfoot.com/2016/08/how-to-disable-driver-signature.html)
4. An older version of MiFlash
5. If all of the above don't work ,try using another PC
6. Also make sure the USB ports are in working condition ( I think yours is working tho)

My pc is 65 bit. I can't try #2 yet since it takes a while for battery to drain. I disabled driver signature enforce and using old mi flash and tried new pc still doesn't work. My boot loader is unlocked but maybe I accidently locked it? I don't know how to check.

Without the brackets, now check for the unlocked line in the output and see if it shows yes or no

2. Oh ok take your time draining it
3. Try fastbooting the ROM via ADB see if that's works too

Oh that means ADB isn't recognizing it.
There isn't much we can do if ADB doens't recognize it!
Did you look up for Service Centres?

I have a xiaomi redmi note 7 pro from china and I was planning on rooting it and changing the rom. Anyways I unlocked boot loader and installed twrp but couldn't install the rom using twrp recovery mode. Then I followed a video which rebooted the phone into recovery mode again after clearing some things. However, before rebooting it says no OS but the video did it anyways. In the video the phone rebooted back into recovery mode fine, but my phone does not boot. It constantly boots up to the redmi logo, flashes and boots again into redmi logo. This continues forever. I can, however, at this point enter fast boot. I thought the problem must be I have no rom so I just need to flash a rom. Using mi flash tool didn't work there was always some error and I turned the phone off. After turning the phone off, I cannot turn it back on again!!! Nothing, not holding power, not holding power + volume, just pure blank can't boot at all. I really don't know wtf I can do know it just doesn't turn on at all no matter what. Please help guys.

I had the same issue, but my phone went to fastboot from there I flashed it, the process was simple :
1. Download the fastboot rom and extract it (I guess two times, the first extraction extracts a file, open that with some extraction tool and uzip again, there you will see the fw with certain folders and images etc ).
2. Download the adb/fastboot zip file I"ll attach that here, extract it to the same folder where your fw files are. (fw = firmware).
3. You will find 3 bat files, flash all, flash all and lock, flash except storage, choose flash all (execute it).
4. Once done, reboot to recovery (stock), do a data wipe again.
This worked for me, hope it does for you too.

He/She said the phone doesn't boot into Fastboot either so that's very unlikely to work :-\
