[Q] strange boot behavior

I had the Photon Q with the SIM mod and CM 9 working for 2 mouth. But yesterday, I were using the cellphone when it reboot itself and get freeze on the unlocked bootloader warning. I try to power it of but y could not, the I let it there until batery drain (about 4 hours)
Now when I boot the cellphone it has an strange behavior. Some times it freeze on the unlocked bootloader warning, other time make a loop boot (show the warning and restart). Also some times it display strange colors on the screen when try to boot and many times it display a randomly sorted grey vertical lines and very few times (one of every 50 times) it boot the ROM but when i touch the screen it goes black.
i can not conect to phone by adb and can not enter recovery, but i can access to the fastboot (in fact the fast boot is working but do not display anything on the screen, i suppouse that the same happend with the recovery. but i can not use it if the screen is black)
I used the fastboot and RSD to flash the stock firmware, the phone return fail on every 4.0.4 ROM but it work with the 4.1.2. After the flash some times thes phone display the morotola and sprint logo and then start the handfree configuration, but when I touch the screen it goes to black again.
I do not know if it is bricked, I think that if i have access to the fastboot i can resurrect the phone. but is very strange the random behavior.
Do you have any idea what should I do?
Thanks.
PS: sorry for my bad english

Re-Strange behaviour
Hi there, one of my Q's (also sim modded) was doing a similar bootloop warning etc. I was screwing around with it a bit. It's all good now though.
The way to force power down/reboot is to hold "volume -" and the power button for 10-15 seconds. If you drain the battery, you will be stuck with more boot-loops due to a flat battery. If you plug the charger in & the LED is green, this means it is charging a dead battery, & will need to charge for a while.
By the way, I had issues on my other Q handset running CM, failing to read the mSD card, and causing freezes, boot loops etc, so I went back to stock. Pretty sure most of the trouble is due to the mSD card read/mount error.
Edit:
Come to think about it - my Q failed after I tried to restore my CM10.1 backup from the previous phone. I suggest this may be contributing to the issue, as you are also running CM.
With the black screen/boot loop, force reboot by holding "vol -" & power button for 15 seconds, release power, then immediately hold "vol +" so it forces boot to recovery (TWRP if you have it).
I restored a previous backup eventually, but TWRP was not working too well after the screwy boot-looping etc. I ran a factory reset from the phone menu once it was running again, then rebooted into TWRP.
Super User wouldn't install from TWRP after, so I pushed it across & installed from TWRP, now I'm about to update TWRP to 2.6.
Still want to have a go at another ROM on this handset, so I can compare it to my stock one. I'm pretty sure CM10.1 was part of the problem on the other Q with my mSD card failing, as it has been fine ever since on stock.
Try this:
Try using adb to fastboot into recovery, then push TWRP (again) onto your Q using this method by arrrghhh http://forum.xda-developers.com/showthread.php?t=1887070
Push Super User across onto your mSD & install that from TWRP as instructed also.
Restore a stock/custom backup from an earlier time if you have one, or flash a fresh download.
Let me know how you go.
P.S. make sure you have "USB Debugging" enabled in developer options in order to ADB fastboot recovery.

I tried it, but do not work.
I flash the stock ROM from fastboot and also flash several recoverys, but never boot any ROM and I think that i access to the recoverys but the screen is black then is very dificult to use it. Is strange beacouse some times screen displays perfect the unlocked bootloader warning, but never display anything on the fastboot or the recovery.
Witch part of the software have the video drivers that are used on the recovery and fastboot? I think that maybe is corrupted. how can i flash it again?
Thanks.

[Q] I have problems with updating lollipop 5.0 in my Nexus 4.

So, my phone was stuck in No Command bootloop. I’ve done the power+volume up and had cleared cache and even done a factory reset. Those did nothing and my phone is still in stuck No Command loop. I think I’ve made it even worse by trying to Flash Recovery and Reboot options in the Nexus Tool Kit because my phone won’t even get to the No Command screen. It just turns on and turns off after Google comes on. Currently it stuck in that loop and only stops once the battery is completely drained. Also i have tried using power + volume up and it doesn't help . Please help

As you've upgraded to lollipop ?? You came from a custom rom ?? Enters the bootloader?

with wugfresh nexus root toolkit click on the button "soft-bricked"(flash stock + unroot) or something like that to restore the phone. After that try another time to unlock and root with a custom recovery (for example twrp).
When nexus root toolkit installing the original lollipop rom, look the "dos window" to see if the software shows errors, because sometimes the process ends without a real restore.
If you have other problems, please post a screenshot.

Yes I was using a custom rom, but I not even reached the step where a was supposed to use the rom, I was steel still cleaning the divece.
Here is a photo from the screen I'm stuck in:
eeee.... I'll find a wint to send the photo to this forum ^^" wait

Every Rom I've tried is just sitting at the boot up logo.

I've tried Carbon but that one wouldn't actually boot up, just shut my screen off and would shut itself off.
AospExtended ROM, is just sitting at these bouncing dots.
Ressurection Remix, sits at the boot screen of whatever that...logo is supposed to be.
I'm at my witts end here and about to smash this piece of junk. Nothing on this phone has ever worked right since I got it. Figured I'd fix it by getting rid of their trash UI and do custom roms but apparently it can't even do THAT right.

Upgrade your device to EMUI 8. Then flash one of the Treble ROMs.

I can't even get into TWRP anymore. It just keeps going into the EMUI recovery everytime I hold down all 3 buttons.

I've found out myself of why those custom roms wont boot, because you did not clear cache and dalvik before you booted to the custom rom. You wont have to smash ur phone if you do this.

That's something I do automatically without thinking. That stuff was finicky back in the OG Droid days so I always do it like 3 times just to make sure.
Anything else that would cause it to get stuck at the booting up screen? I get passed the blue screen and the your device is insecure or whatever. Then it just goes into the fancy booting logo and just sits there. Never on any of the phones I've rooted over the past decade ever got stuck like this.
WOHOOO! I MADE PROGRESS!
My phone is now stuck in a never ending bootloop and can't seem to get into any recovery. Can't even shut the phone off because it just turns itself back on. Backwards progress is where it's AT!

Bump, any ideas?
I went back to Motorola and bought an X4 but I'd like to get this working again so I can sell it.

What honor 8 model do you use? It should not be Bootlooping then, if there is no solution you can always go to stock.
You could flash twrp again, with fastboot
Boot with power + volume up to boot into twrp

Use dload method

[SYSTEM] Bootloop Xiaomi Redmi 7 (Onclite)

Hello I have a Xiaomi Redmi 7 (Onclite version) - 3GB 32gb, I have had this cell phone for a few months without any problem, I have been able to perform tasks such as unlocking bootloader installing custom roms, among many others, 2 weeks ago I installed the global version 11.7 in recovery mode and the phone worked normal until today, out of nowhere the phone was restarted and the only thing it shows is over and over the Redmi by Xiaomi logo, it is constantly rebooting showing this logo.
Things that I tried to fix this problem:
1. First I thought that was a problem with the room, so I proceeded to go to recovery mode but the phone shows the recovery image and after 4 seconds it reboots.
2. In fastboot mode the phone automatically reboots after 15 seconds approximately, for this reason I can't try with another room, flashing the stock room, only i can change the recovery image but i tried with 3 different versions and doesnt works.
Briefing the phone are constantly rebooting even in recovery mode and fastboot mode
If anyone knows how to solve this problem, I would appreciate it infinitely, thanks

Flashed wrong recovery. Re-flashed correct recovery. Installed ROM. Phone turns off randomly while plugged out of charger and says no battery left.

Please help me out as I messed my phone up real bad recently and I need to fix it as soon as I can as I have interviews right now and need to be updated with them.
So here's what I did:
I was using Pixel Experience ROM on Android 12, with OrangeFox recovery, it was working fine with no major issues.
I really wanted to try out Android 13 though it's still in Beta but I have heard good things about it, specially the one by Project Elixir.
But since I was already using Pixel Experience and loved the ROM so much, I decided to be on the safer side and look if they have a Android 13 ROM for my phone.
That's where the story began, I mistook the Redmi Note 7 forum (lavender) as Redmi Note 7 Pro forum, I forgot how they were two separate devices.
So I flashed the Redmi Note 7 recovery on my phone and it it didn't boot into recovery when I tried it to, then I downloaded the original (correct one) from OrangeFox's official site and flashed it after which the recovery works. But then as I tried installing the new ROM, my adb sideload kept getting stuck at "Starting ADB Sideload feature" and I couldn't make it work, so I flashed the new OS from my sdcard. It was all fine, I set it up and was loving the experience until I plugged it out of the charger. After a few minutes of plugging it out of the charger, it literally started rebooting and it restarts just in the middle of the boot animation. And when I manually power it on by pressing and holding the power button, it displays that It has no charge left.
I tried flashing quite a few other ROMs too, even Android 12 and 13 both, and at a point for some reason it also showed "system has been destroyed. press the power button to shut down" while booting into recovery but it went away once I re-flashed the recovery, and after no luck, I flashed MIUI but the same thing still persists.
I read in a few forums that it might be a battery issue which I too thought at first but the fact that it happened exactly after I flashed the wrong recovery bothers me. I thought installing the stock MIUI rom through fastboot would solve it by replacing every corrupted files and partitions but the issue seems to persist.
What might have been the issue and what can I do to fix it, and can flashing a wrong recovery cause this even if I have flashed the right one just after that?
