N4 Semi-Brick? Can I recover? - Nexus 4 Q&A, Help & Troubleshooting

Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!

[Q] Need help - HK MX 030 won't boot

Hello everyone!
My brother sent me is MX 030. It is the original Meizu MX HK version with the unlocked bootloader. Two weeks ago, he found his phone had crashed. The screen was black and he powering it off and then back on would not do anything (black screen - only vibrates on power on).
I got it today and first thing I did (after charging it-the charging mode works and displays a battery logo) was boot into recovery mode (or update mode on Meizu phones) and I was able to reach the menu. It let me mount the drive onto my PC. I downloaded the latest firmware and put it on the drive. I pressed upgrade and cleared data. The software seemed to install fine, but then the phone rebooted to a black screen - again.
Then I tried installing older versions which I found on the meizu website. They all install and I can see the recovery mode is different, but they all boot into black unresponsive mode (which drains the battery).
Having had other android devices before, I feel the phone is stuck in reboot loop.. I don't know what else to try or attempt. I feel am running out of options. The fact that the phone still responds to some commands and allows me to flash firmware should indicate that the phone isn't brain dead quite yet, right? Anyone else experienced a similar situation?
Thank you,
Oli

unable to enter recovery mode..stuck at lg logo

My wife killed her phone. She had romboons 30 installed with dorimanx 4.2 kernel and blastagators twrp 2.8.7.1
She then started installing other roms and now the phone is stuck at lg logo bootloop. I tried every button combination to get into recovery but notting
Tried download mode but it says rooted and freezes.
I am running linux lite 2.4 and am not that experienced at it.
My wife knows that its her own fault that the phone doesnt work anymore but is there a way to get it back to life again?
Thanks a lot for your help
Edit: Been trying to get into recovery mode for the past 3 hours. tried all combinations but notting. I only am able to get into a screen for hardware buttons. Download mode doesnt work either. phone is detected by linux when i hook it up.
I think the wife finally completely killed the poor phone It does not want to go into recovery
Well will mean that i will have to learn how to live without a phone cause she already took mine as replacement.
I have been able to get into recovery after several hours and installed new rom. So this can be closed and if you want even be deleted

[SM-G900F] Device reboots 3 seconds after display goes off

Device was working fine until OTA update to 6.0.1 (MMB29M.G900FXXU1CQDA). It wouldn't boot past the Samsung logo.
I downloaded that same firmware (and the one before) and flashed it via Odin 3.12.7, however situation remained the same.
Flashed TWRP 2.8.7.0 and then PhoenixROM 15.0 and device booted fine. However it would always reboot after display stays off for 3 seconds.
Flashed TWRP 3.1.0-1 and then LineageOS 14.1-20170802 and device booted fine again. The reboot problem remained the same.
The reboot problem is NOT present while device is connected to a PC, however it is present while connected to an AC wall socket.
Each time the display goes off the device stays off for 15 seconds before booting again.
Anyone got similar experience, any advice?

Did. Same case as with Marshmallow.
However there has been further issues, seems the phone can't be saved.
After flashing Lolipop the phone wouldn't boot via power button, but instead I need to boot it to Download mode and hit cancel.
This however makes it go to Recovery mode. Trying to boot the system from Recovery makes it power off.
Tried flashing TWRP back and when I enter it, the device keeps choosing random options rapidly, as if it's constantly detecting touch across the screen.
Therefore I'm no longer able to flash LineageOS back.
Gave up on the device in the end, seems to be defective.

It sounds like the touch screen is going wonky. Or the mobo has an issue. You could get it diagnosed at a shop reasonably cheap

Does the phone boot properly to the desktop after flashing the latest stock ROM?
yes it boots normal
btw little update i found out i can use my recovery my screen just dont show any thing
i found that out because everytime i was downgrading from 5.1.0 to 4.4.2 i had to do wipe data or it wont boot
i tryed to go in recovery and go 3 down (wipe data) and then 7 down (yes) just with youtube videos and it worked before the wipe my phone does not start on 4.4.2
that means that my recovery is working but screen just doesnt show it
it doesnt show anything but the white samsung logo, normal system, downloadmode
at any other time my display ist blank
as an example when i turn it on i see the white logo then screen turns blank i hear the bootup sound, after 15 sec screen goes black and when i press unlock i can normal use the phone
but why is it blank while booting and in recovery and also is a bit flickering when phone is turned on normal

i called in a repair shop they told me maybe the backlight control is broken???
because i also cant change my brightness its set to max and doesent get darker when i move the slider

Need help to unbrick my phone

Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.
