A friend has given me his N4 in an attempt to fix it, seemingly the problem was caused with him doing a factory reset. It's possible the battery went flat during.
The phone gets stuck at the boot logo and will not factory reset from recovery mode. I can unlock the phone but any attempt to flash the stock image will result in the phone re-locking itself a few seconds later and the flash then begins to fail. Very odd.
Any ideas where to go next?
Thanks
Sounds like it could be faulty motherboard, bootloader not unlocking properly is a common symptom.
Sounds like bad emmc, hardware issues. You will have to replace the device.

Before replacing anything I would suggest to update your recovery and try flashing again
And don't forget to wipe the system partition.

So I think my Nexus 6P is hard bricked, but I just want to be sure before I issue an RMA.
I was on a plane flying over the Pyrenees and opened the camera to take a picture. The phone froze and started rebooting, which I found strange really strange as it never happened before. Since then, it wasn't able to boot again. The phone is completely stock, running 7.0, apart from the unlocked bootloader that I had unlocked the day I bought it (March/April this year). The phone shows the unlocked bootloader warning, goes to the white Google logo with the padlock below, and then goes back to the unlocked bootloader.
From here I can Power + Vol down and get to bootloader, which I thought would leave me to recover the phone somehow. I know my way around nexus devices so the first thing I tried was scrolling in the bootloader menu and boot into stock recovery. No luck, unlocked bootloader warning, white Google logo and loop. Tried "Factory" in the menu and the same thing happens.
So then I've gained access to a computer and tried downloading a twrp recovery and boot into it. Ran fastboot boot twrp.img, the phone tries to boot again, and the same thing happens. Boot loop. After that, I've downloaded the latest stock Google images and I've run a different set of things, all with no luck. Booting directly from fastboot into stock recovery doesn't work. Flashing stock recovery and trying to enter stock recovery via bootloader menu doesn't work. I've erased and flashed bootloader, radio, and all other partitions (system, boot, recovery, vendor and cache), without any luck. The fastboot commands return "OKAY" but it seems like it's doing nothing.
I am out of ideas, I always thought I would be able to recover a Nexus phone as long as I could reach bootloader mode, but I guess I'm wrong. Should I RMA, or is there anything else I should try?
Thank you.
You say you "Ran fastboot boot twrp.img." Try to do fastboot flash recovery twrp.img from fastboot and see if you can get twrp working. Then try to flash a ROM

Done both, actually. Tried to boot directly from a fastboot command and then tried flashing the actual recovery image to the phone. No luck in both. Never able to get into twrp.
I had the same thing happening to me. I was also using stock 7.0 with an unlocked bootloader. My screen froze during webbrowsing and had to restart the phone. Once booting up, it never came past the Google logo. Getting into recovery didn't work either, just started looping again. Tried to flash twrp, got in there after many tries. Tried flashing all kind of android versions but nothing helped. After that I decided to just use my warrenty and send the phone to the store. They replaced the motherboard and are now sending it back.

Yep, I gave up already. Tried all different sort of thing, and was never able to get into any kind of recovery, let alone Android itself.
Called Google support yesterday evening, a replacement is on its way already.

Needed the RMA anyways. If you had an unlocked bootloader and formatted each partition and then flashed each partition with the corresponding image file from the latest factory image, it was shot. It happens from time to time. Happened to mine as well. 2 or 3 days after I finally got it (pre ordered on launch) I rebooted the phone at some point 2 or 3 days later and it just never turned back on. 100% bone stock. Not even an unlocked bootloader. Nothing would happen when I plugged it into a PC, left it on AC power for hours and hours and still nothing. Holding power 10-15 seconds, nada. RMA'd and luckily this one's been perfect ever since. Good luck with the new device!
I tried factory reset+cache wipe, smart switch emergency recovery, flashing rom with odin but I'm still getting this inexplicable boot loop that started on its own. Also tried TWRP wipes but those didn't help either. How can I even begin to troubleshoot this or possibly get a fix?
It sounds like you have an issue with the memory chip on your motherboard.
Since all the conventional methods failed, you will need to take to a cell shop that has professional equipment to try and restore it.
If they cannot do it then you need to replace the motherboard through samsung.
VS995 Unlocked with dirty santa, Konverged kernel, stock rom
The other day phone just randomly shut off without warning, battery was low (5%) so I figured battery just died. Went to plug phone in, got to the "device cannot be trusted" screen and to the LG screen, screen goes black, and gives me this yellow "RPM Crash" screen (see below). I can boot into fastboot just fine, and up until just a few minutes ago I was able to boot into twrp by flashing my twrp image as boot and rebooting the phone (if I use the button method it gives me the factory reset screens, goes to the lg screen, and goes back to the crash screen). I can reboot to recovery from twrp and it works just fine. Booting into download mode shows the download mode icon for a few seconds and then it goes black and to the crash screen.
Issues found/fixed so far
I saw in another thread someone had a boot.img issue so I messed with the boot1 and boot2 imgs from the dirty santa process and managed to get to a looping verizon screen with boot1 and the encryption unsuccessful screen with the boot2.img
In twrp my data and dalvik partitions were corrupted but I was able to reformat and repair them. (I found out when trying to wipe them in fastboot)
In fastboot, after working in twrp I was able to wipe and reflash all partitions except system I extracted from a kdz with no luck as far as getting past the error.
My system partition is currently wiped and I have not flashed a new system.img as fastboot won't let me flash it and I cannot get back into twrp to flash it.
I'm curious if this is more of a hardware fault than it is a software fault as download mode was also affected
Thoughts? Suggestions?

I have a H910 that just received a screen replacement and I am also getting the yellow error screen. I am still able to get into Twrp though. However no matter how many times I flash a Rom, it keeps getting stuck at the yellow screen.

Can you take a picture of of the screen, or is it identical to the one that has been posted? My guess is that you put the wrong screen on.

Here is the photo, sorry it's not the best quality since it's taken with a OnePlus One.
I had gotten the screen replaced by a cell phone repair shop. Luckily they still gave me the original screen. If it's a bad screen I will just get them to switch it out again...
You will have to upload a better quality picture for me to be sure, but I can tell you that you are getting an selinux failure for some reason when it is trying to load some driver. Again, I need a better picture.

Sorry for the delay, I had the repair shop reinstall the original screen I was using. I am still getting an error screen, but I have my actual camera with me so here you go. I have tried installing a new ROM, I've tried doing "STEP3.BAT": https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500 Because thought it needed a new boot.img
Still having errors. Any advice would be great. I haven't reverted back to stock because not sure how, and worried I'll lose twrp and would prevent me from actually doing anything.
I have a LG g4 that got the blue screen of death and it won't respond to anything I've tried so I'd say this is the same...........
my lg v20 started displaying this RPM crash screen two days ago. I am not certain what caused it, but it was immediately after charging it with a power bank. To boot mine, I have to plug the phone to a wall charger, once it shows charging, I press the power button and it will boot flawlessly, after that I am free to unplug it. I cant say if it wouldnt degenerate and I havent tried flashing the phone afresh. For now, I would back up my data to avoid surprises.

How do you boot into twrp? I am unable to. Are you currently able to copy your files from your internal memory to sd via twrp?
A couple of days ago. I wanted to check my phone in the morning and it started boot looping when I pressed the power button. Then, after a couple of boots it went into the TWRP recovery. I wiped cache/dalvik in hopes of a quick fix but still boots into recovery.
I can also go into the bootloader but the bootloader is completely unresponsive. It just gets stuck on the "barcodes" option, the volume keys do nothing and adb doesn't see my device when it's in the bootloader. I also tried re-flashing the same ROM I'm using(within recovery) to no avail.
I still intended on using this thing for a couple more years (I have a couple of spare OEM batteries and a spare chasis). Really appreciate any help.
Recovery.log from TWRP
Any flash drive can become corrupted.
Boot loops are commonly caused by poorly coded apps like launchers and power management apps.
Rootkits are always suspect with abnormal boot ups and unstable operation when no other cause can be found.
On a stock Android a factory reset or in extreme cases a firmware reflash will resolve it unless it's a hardware failure which is rare*. Be careful what you flash, install and download... always.
*a drop, water exposure or a ESD event when repairing a phone can cause this... sometimes not immediately.

Can I reflash firmware without the download mode working properly?
Sorry, way beyond my skillset...
Hi guys,
A few days into this fiasco now aha - my Pixel 4 seems to be (nearly entirely?) bricked.. won't turn on past the fastboot screen, pretty much stuck in a loop there.
I fear that I may have wiped it entirely or otherwise severely corrupted it. Was originally trying to root it, but never got that far and ended up in this mess.
I have tried to re-flash from the website as well as the batch file but it keeps getting stuck on the "fastbootd" screen when "uploading partition data 1/10".
I can access fastboot mode. It is unlocked. Cables and all that are definitely fine. Just can't bring it back to android.
Thanks for any help in advance
Edit: here's a link to the flashing process and what happens - Video
Anyone? Aha
have you tried to flash factory image locally? (instead of web flasher?)
what does the fastboot screen say when it boots into fastboot?
(It gives a reason for having booted into fastboot)
