[Q] Deactivated Nexus S 4G stuck on unlock bootloader screen

Ok, so had it unlocked, but running stock. Ran fine, then one day it stopped working and got stuck in a boot loop on the google screen. Managed to get it into CWM and then wiped, after lots of tries, and back to CM7 and unlocked. Then backed it out to stock and locked the bootloader(was planning on giving it to a friend who doesn't like to play with phones like that). But now it gets stuck on the google screen. Can get to fastboot, but if I do fastboot oem unlock it just has "..." and holds for hours(until I manually stop it) and then says it failed too many links. Can't get it unlocked, can't get it to boot into anything usable(either fastboot or the google screen and no further) and I'd really like to turn it back into a tablet for the kids to use since I've moved on. ADB devices shows error device not found but fastboot devices shows the serial number. I just really need to know how to unlock it so I can get it back and running. I think what screwed it up was I flashed it back to the way it came locked bootloader and then it said there was a OTA update, I said ok, downloaded it and when it rebooted it wouldn't go past google screen or past fastboot screen. If I try and do the recovery I get the triangle with exclamation point(yellow) and if I hit the power button a few times it tries to reboot and hangs. And yes, when I do the unlock the screen comes up, I move it to yes, hit power and then it freezes. Thoughts? Thanks in advance.
Ever Fix This?
Did you ever get this figured out? This is where I'm at after hours and hours to get to this point.

Boot verification certify - LG G2 D800

I have the AT&T variant (D800), and got a popup that a software update from AT&T was available, so I tried to install it. The phone was rooted, and I think I had the stock recovery. I tried to flash CWM using ROM Manager from the Play Store, but everytime I tried to boot into recovery I got the "Error: boot certification error" on the LG logo screen.
So I tried to get the software update, which turned the phone off. It didn't boot up for like half an hour, so I tried to turn it on. I got the "Boot certification error," and then the phone went to the black screen. If I shut down by holding the power button and then turn it on again, same thing happens. Before, doing this would have booted the phone into the OS. Now it just repeats the error. What can I do? I'm getting it warrantied tomorrow, but if it's possible I'd like to avoid it.

[Q] Can't recovery boot, but can normal boot

I have recently been playing around with my Galaxy S III and looking at different things. My S III has been rooted using towelroot, and the other day I was trying to change the boot logo. I found one, installed it, then decided to boot into recovery mode. When it restarted, it gave me the error "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help." along with "SECURE FAIL: KERNEL." I started panicking, but I then remembered to try to flash the original ROM onto the phone using ODIN. I got into download mode, but then figured out I couldn't find a cord anywhere. I shut down the phone after booting into download mode, and it booted just fine afterwords. I then shut down the phone, and tried recovery mode once more, with no luck.
I was wondering if it was off that I can access download mode, the normal OS, but not recovery mode.

Samsung Galaxy S6 (sprint variant) failed firmware flash FAC LOCK

Let me start by addressing I know this isn't the sprint thread but there's a lot more development here which equals more help. Plus this issue seems to be able to happen to any variant.
Second, this isn't my device I'm trying to see if it can be fixed for a friend. I'm not that familiar with Samsung devices but I have been able to get them working in the past via Odin or kies but this time I need some help.
So this is what's going on, my friend recently rooted his S6(SM-920P) not sure which method he used (don't think it matters at this stage) and was on stock rom (LP5.0.2) with xposed framework installed. He hadn't changed the kernel AFAIK oh but I did install TWRP for him and everything was working. Long story short he woke up a couple days ago to his phone being unable to turn back on. I told him how to get to download mode and I asked him what did it say on the top left corner it said something like "system binary not SEandroid locked" underneath that it said fac lock
So I had him give me the phone thinking somehow it did a OTA update while he was asleep or something either way I was confident using Odin to flash the firmware would solve the issue. Had the firmware finished flashing I'm confident it would have but halfway through Odin simply froze on installing system. I figured its just gonna take a while 45 mins later it was still stuck at the same spot.
Not really thinking about it I figured I will just reboot the phone back into download mode restart the process it should be fine. Not a good idea. Now all I get is a green screen saying to access the smart switch emergency recovery system. But it gets better.
My computer isn't recognizing the device now. I installed smart switch software and it's not recognizing it. I even installed Kies and it's not recognizing either.
Is his phone toast or what? I tried emergency system recovery but I need the S/N of his phone to possibly get this thing working again, but it boot into anything anymore except the screen that says Samsung switch...
PLEASE HELP ME if it's bricked it's bricked I get that but if there's a way to figure out what to do I'm all ears. Thanks in advance

Unrooted my Moto G7 Power to update and now it will not boot

I unrooted my phone through Magisk Manager to get the Android 10 update, and I guess I missed a step. Because when my phone rebooted, it comes up with the "No Command" screen after showing the unlocked bootloader warning.
I am able to enter the recovery mode and all of those settings, but my phone wont boot normally. It doesn't even show the Motorola "M". If I leave it on for a bit, it will switch between the unlocked bootloader warning and the no command screen. I've already tried a factory reset but that does nothing.
Am I stuck with a broken phone, or is there another hope? I'll do my best to provide more info if needed. Please help!
