OnePlus 3T won't boot after LineageOS 14.1 flashed. - OnePlus 3T Questions & Answers

Hi everyone,
I have received Oneplus 3T today. Rotted by instructions, all was perfectly OK. Tried to flash latest nightly of LineageOS, but got an Error 7, which means I have to flash experimental rom first. That is what I did. Battery was at 100% before I started. Only few minutes I noticed that screen is black. Phone does not react to what ever I do. I noticed that when I attach usb cable, the PC reacts to it. And when I hold power button, on pc I can hear "ding" which means "connected/disconnected".
How can I fix this?

Samsung Galaxy S3 mini is completely dead

Yesterday evening my phone was on the charger then it suddenly stopped and it is completely dead. It isn't showing any signs of life ever since, even if I charge it. It doesn't even show offline charging and I can't send it to Samsung as it's rooted so my warranty it VOID. It seems to me that it has Sudden Death Syndrome because it has been recently been switching off and now it's completely dead. What should I do? I'm pretty much screwed!

Well... I managed to just get it into offline charging. When I boot it up in normal mode it shows Samsung Galaxy S3 mini then after a few seconds the bottom lights flash for half a second and shut down. When I try to boot to recovery, model name then shut down. Yes it can just about make it into download mode.

If you get into download mode, go to sammobile en download the firmware for your phone and flash it with odin. if that worked, open stock recovery and do a fatory reset to make sure everything is back to stock... Then you can just hope it won't happen again.

I tried flashing stock recovery and ROM through Odin, it said pass but nothing actually seemed to fix and it still has the same problem that it shuts down after showing logo and when I boot to recovery it just shows TeamWin for a few seconds and shuts down so looks like I'm screwed and I have to use my BlackBerry :'(

And I don't think Samsung will repair it as my warranty is void and I doubt if my parents would get me a new phone as this phone is only 3 months as well! And I have seen an unbrick thread and I tried it and it didn't work :'(
Well, I know how you feel. My charging port died once after I changed rom. Samsung asked me 200 for repair. Maybe you can give it a try and send him in... You never know Samsung loves you more than me..

Have you any news about the problem in your phone?
Mine (i8190 with one of the mclaws roms from previous week) also appeared in the morning shut down and there's no way of starting it. It does not even vibrate when power button pressed, as if the battery was completely empty.
Tried with another battery and checked that the original one had charge, but no luck. It does not start (normal, download or recovery, makes no difference).
Any ideas?

Well mine was dead for a day then I plugged it into the charger (this was after a day and I left it on charge all night and it wouldn't start) and I held the power button for 10 seconds while it was on the charger it showed offline charging so I let it charge for a bit and then I powered it on and it seemed to be bricked so I sent it to a phone repair shop (not Samsung as my warranty is void). If it doesn't show any signs of life then it's bricked. If it comes to life then it is also probably bricked. I tried flashing many recoveries, ROMs, kernels and params and nothing happened.
In the S III Mini General forum there are topics about getting your phone back to stock so that it is covered by warranty.

I tried to flash stock ROM and recovery but nothing actually worked!
1. Did you follow the instructions in detail?
2. What does "nothing actually worked!!" mean??
Maybe you need to work out what is the problem and why it is failing. Then you will be able to figure out if it is actually fixable, and if so how to fix it. "Trying everything" doesn't really work unless you make an effort to analyse the results you get every time you try something.
You could try posting in one of the threads about taking the phone back to stock. The people who posted them might be able to help you, they are more experienced at this sort of thing.

Kid, can you read?
What did you try? What was the result?
"didn't work" isn't a result, it's you giving up. Without even trying to find out why it didn't work.

[support] OP3T will not turn on at all after flashing OOS Beta 9 after a soft-brick

Hello everyone. I updated my rooted OP3T (with TWRP installed for recovery) to OOS 4.0.1(I think? I know for sure it was 4.0.x) a week or so ago using a VPN as I live in the US and today I got the new update for whatever version that was about 30 mb, and after I rebooted I got stuck booting into TWRP so I followed the guide linked underneath here and got up to step 12 (flashing beta 9) and after swiping to restart my phone will not turn on in any way, shape, or form. Whenever I plug it in/unplug it from my computer I'll still get the Win10 device connected/disconnected sound and if I hold the power button for long enough while it's plugged in I'll get another device connected sound or disconnected, usually followed by the opposite sound. There doesn't seem to be a pattern to the sounds, but if anyone knows what's happening I really need help with this as it's the only phone I was able to afford and if it's bricked I don't know if I have the money for another one. Thanks

Lol no wonder your phone doesn't work anymore. You flashed the beta to the OP 3 onto your 3T. Use this to fix your phone.
Edit: Sorry if this was of use to some people when it was deleted.

I tried to use that thread, but my phone wouldn't show up underneath Unknown Devices, in fact unknown devices would never come up at all. my pc is still in test mode from this :/
Don't worry if it doesn't appear under unknown devices. Just use the tool. A lot of what the instructions say is unnecessary. Just make sure that when you plug in your phone that one of the ports becomes "active" (I haven't had to use this tool in months, so I'm not sure exactly what it's supposed to say exactly) and press the start button.
Edit: Sorry if this was of use to some people when it was deleted.
ok. I 'll download the tool and get back to you after trying it.
edit:that worked! you are my new favorite person.
thank you so much )))))))))

WHY IS THIS DELETED? IM having the same problem what did you do please save me as well
Sounds like you flashed the wrong version of Oneplus 3 firmware to your phone. Do you have a 3 or a 3t? If you flash the incorrect one you will get exactly the unbootable state you describe. In that case you will have to use Qualcomm MSM Downloader tool to flash back the correct ROM and firmware partitions to get it running again. Just download the correct MSM recovery package for your phone and follow the instructions in the thread.

OP3T is not turning on at all after flashing OP3 Resurrection Remix ROM

Hello Everyone. I accidently flashed OP3 Resurrection Remix ROM to my OP3T. I have been using it for more than 4 months and It is rooted with some instructions I found in XDA post and it worked fine after that. Later I decided to get Resurrection Remix ROM but later I found out it was under OP3 thread. I followed steps listed in the thread and I first full wiped it, then installed Firmware & Modem 4.1.1 then the Rom and as well as the Open Gapps and then clicked to restart. I knew it will take some time to boot up and didn't at my phone for 5 minutes. After some time I look at my phone and I see it is not working and I tried to turn it on and hold the power button for some time and Tried to get to recovery and bootloader page. I tried to plug into the charger and I left it plugged in for a half hour and nothing changed and I tried to plug it in my computer and my PC didn't recognize phone was plugged in. I searched for similar problems on xda and I found one post had a little similar problem but it didn't help. I am new to xda and sorry for my bad English. Thanks.

Have you tried carefully following the unbrick steps/tutorial? I'm sure you can fix this by yourself if you carefully follow every steps. I was once in the same situation as you and I can fix it by following the unbrick tutorial by HarisK.

Yes I found guide on xda on how to unbrick my hard bricked OP3T and it worked. Thank you
That's scary. In glad you figured it a solution! Never had to use the unbrick tool yet myself, but I'm sure I'll visit it Someday lol
The OP3 firmwares is incompatible with the OP3T, therefore your have to be extra careful around these cross-compatible ROMs as to not flash the wrong device firmwares.

Rooted one plus 3t with corrupted recovery stuck on bootloader

Hello everyone. First of all, sorry for the long post.
I just bought a OnePlus 3t three days back. Updated it to oxygen 4.1.3 and then rooted it as well. Everything was working fine. But then I decided to downgrade to 3.5.4 since I wanted to try out Xposed Framework. So I downloaded the OS from OP Support website, and went to twrp recovery and installed the os 3.5.4 from the internal memory of the phone. It seemed to install properly but when I rebooted the phone, it started asking for a password. I tried every possible combinations of my passwords but to no avail. I saw online and found some video where I was supposed to flash a new recovery which I did. After that the phone got stuck in Bootloader. There is no bootloader and recovery version detail available on this screen.
If I try to restart the phone it gives me the following error, "Decryption Unsuccessful - Your phone storage has been damaged, unable to read data stored in your phone! To continue to use the phone, you need to reset the phone." There's a button at the bottom of the screen to Reset Phone. When I click that the phone goes back to bootloader mode.
Please help me out here. I have no clue what to do right now. I have tried flashing several recoveries but they give an error "cannot determine the image filename for abcd.img"
Any and all suggestions are welcome. Thanks in anticipation.

Thank you for the reply. I haven't yet tried it, since the computer recognises the phone just fine. It even shows up in the fastboot devices list in cmd. Maybe, I should give it a go.

Ok so I did manage to reinstall twrp. But I have no idea what to do next. Any suggestions ?
I managed to fix it. After the twrp recovery was installed, it started asking me for a password. Which I tried and didn't work. But then I just wiped the phone and it went back to factory settings somehow.
Now the phone is back to oxygen 3.5.4 and works fine.
Hope this can be helpful to someone else.
I'm glad u fixed it
Can u please post the correct steps to avoid this issue in the first place .
I'm on 3.5.4 but I may want to try latest versions and come back to 3.5.4

Do I have a dead Mi9

So have I done something that apparently no one else has on XDA.
Hard bricked my Mi9?
I have heard that you cannot go back from Miui 11 to Miui 10 on China based models or try an install a rom with a locked bootloader.
None of those things are the case here as this is a global Mi9 purchased within New Zealand.
None of the usual tricks work. No battery light black screen no input response from buttons.
Appears like a total hard brick an I have no idea why. Does anyone have any suggestions or experience with hard bricked Mi9s that have bricked for no reason after I did standard things an the bootloader was unlocked?

Now its time to fix the hard brick.
Charge your phone for 30-40 minute. No problem if it doesn't show.
On your laptop or PC
Go to this site and download the stock firmware and mi 9 flash tool
And adb driver too
Then connect to PC
And do what ever mentioned there

No. No luck with my Mi9. And now ive bricked my Redmi note 8 pro.
Looking at the redmi note 8. Easier to flash an mod an not so costly to replace lol.
Not as power ful as other cells but has many roms already. Around $360NZD. the Redmi note 8 pro was $502 an my Mi9 origionally was $860.
I dont need a flagship. Just something good that I can change to suit myself.
