FastBoot loop - Motorola Photon Q 4G LTE

I was having issues with my Motorola Photon Q LTE with the Stock ROM (it has bootloader unlocked and Rooted), but the problem was, when running apps that play video, they wouldn't work (it would just show a white screen with a film icon). Other phones work, just the Motorola Photon Q LTE was having issues with it. So, I figured i'd try another ROM....I had one problem after another with getting ROMs to work. Carbon ROM would install but would force close FaceBook (which is needed), another ROM gave an encryption error. I went between 2 or 3 recoveries and then found someone that said they had a "stock JB" ROM....I was tired and frustrated and wound up just clicking things b/c at this point, I was ready to toss the phone on the ground so hard that it would make it's way to the center of the earth! But, now i'm stuck on the FastBoot screen with it saying "Battery Low" so I can't flash a recovery onto it again. The battery was at 70% when I was in TWRP before that happened....now I can't get even get into Recovery or anything...

Okay, I think I got it fixed now......I managed to get it to take a charge. I had to plug it in, let it get to FastBoot and then push the Power Button....NOT hold it...just push it and it would turn the display off and start charging....its at TWRP now and installing a ROM...HOPEFULLY I can get passed the "Encryption Error" issue...

[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.

Phone shuts off when trying to get into recovery

I just bought my wife a new phone (Razr hd ftw) because she was on the original razr and its pretty much no good anymore. I was giving her the luxury phone treatment. I rooted it, unlocked the bootloader, installed CWM, and installed cm11. Everything was going great but now for some reason when I try to get into the recovery...i get the moto logo, and its just shuts off. I flashed a new recovery twice, and it shows success on my cmd window, but its still shutting off when I try to get into recovery menu. Any suggestions?
**Update** I was able to get back into recovery after trying over and over again. I still have the issue where it shuts off, but its random. I wonder whats wrong :-/
Which version of CWM are you using and where did you get it?
This isn't the correct place to asking for help...

[Q] venom rom sent me to infinate htc boot screen upon reboot

this is my first htc and so far i am missing my samsung and motos
the phone is now completely non responsive and is stalled at the HTC boot screen with the text "this build is for development purposes only " i have the verizon htc one m8 ive tried removing the sd and sim holding power holding volume and power nothing makes a difference.
rooted with s off twrp is my custom recovery
started by putting slimrom on for a change of pace i had horrible signal strength and decided to try another rom somewhere in the process of flashing venom one my sd lost its backups the phone had stayed on the same screen for a while but eventually booted to a stable seeming venom rom and had 3g but no 4g service i ended up rebooting the phone today around 11 am and its been in this loop / screen since. i let the battery die down and was able to get to recovery and searched for my back ups but they were gone i ended up rebooting and now am stuck on the same screen as before. even after trying to enter recovery twrp it goes back to htc and not twrp
i tried every combination of buttons the few times and have drained the battery twice and now it just boots to this screen and is non responsive. hope that i can manage to find a way to push something to it or enter recovery and go back to stock using ruu's
anyone with input or advice would be a blessing at this point id be happy to make a donation for any useful help / anything to get me out of this screen even so i can push another rom or ruu to get me to stock
im afraid ive ruined a perfectly awesome phone
update got back to twrp and tried to re flash the venom one rom after full wipe but used their option for "stock" install said 100% and sucessful but upon the reboot is now seems to be stuck in the same screen.
got into the recover after battery died re flashed venom
after about 15 minutes on the htc screen it went to set up ....still very buggy more so than last time the phone was actually working but it is at least from what i can tell working ... going to try to get back to square one somehow
screen wont turn on and acts very buggy only time it stays on is holding power and gives reboot options... i done f ' ed this phone up.
How long are you waiting after I restarts when the install is finished? It will take a long time on that first boot. I have seen them take more than 5 minutes and if you interrupt it it can cause problems.

Softbricked Falcon XT1032

Hello guys.
I apologize for making yet another "my phone is soft-bricked" thread, but I have been through at least 20-25 of the other threads, seemingly tried everything, and I can't get past my problem. Also, most of the other threads I saw are pretty old and not really active anymore. A few of the tools there can't even be downloaded anymore because the links are dead.
Anyway, here's my story.
I have a 16 GB US retail XT1032 that I bought mostly to give tech support to my parents, whom I also bought a 8GB each. Theirs, I left untouched. Mine, I unlocked bootloader and rooted right away. All went well for a long time.
My parents kept receiving OTA's and it took them all the way to Lollipop. Me being rooted, I got stuck in KitKat somewhere (I'm not 100% sure whether that was in 4.4.2 or 4.4.4), but since it wasn't my daily driver, I let it lie as stock rooted KitKat. Recently I wanted to go to Lollipop in order to keep seeing "the same things" as my parents, and I installed TWRP in preparation to flash a "stock enhanced" version of Lollipop. TWRP flashed fine but there was something funny all along: I could use ADB or a root app to boot into recovery from the ROM, but I could never manage to get the phone to go into recovery by booting into fastboot (vol down+power) and then choosing recovery. Screen would go black and recovery would never load.
So I copied a "stock" Lollipop image and booted into TWRP from the ROM and wiped everything and tried flashing the Lollipop ROM. It got stuck somewhere part way, and a few hours later there was no more progress.
Ever since then, I am stuck in fastboot. Fastboot seemingly works correctly, recently I was able to flash an OG animation to get rid of the nasty "your bootloader is unlocked" warning. I can flash recoveries (TWRP and/or CWM) without error on the phone or the computer, but when I try to then boot into recovery using the bootloader, I get stuck on the black screen and go nowhere.
As others in the various threads have commented, when I try to boot "normally", I get the boot animation and a vibration and then it gets stuck.
I have tried so many things by reading different threads I couldn't tell you anymore what all of them were. I've gotten errors about downgrading, I've gotten stuck in fastboot reason: "failed flash", I've gotten flashing errors about the size of recovery or boot or gpt. What I've never managed to do again is to boot into anything other than bootloader. No recovery and no ROM.
Could someone with a bit of experience please point me to some working links and/or when you have the time, help me look at a couple of logs or something that can help me figure out where my problem lies and how to get out of it? my daily driver phablet died a gruesome death and I wanted to go back to my trusty moto g, to no avail.
Thank you very much to whomever can help.
Ruben.
Try to reflash full stock firmware for your device according to your bootloader version. Hope it helps....
Try typing in fastboot devices

[Q] Google logo bootloop after flashing TWRP

Last night I tried to flash TWRP just because I wanted to go to a custom ROM- alas, the phone now will not go past the google logo. It usually hangs there for 10-ish seconds and then reboots. Occasionally hangs there indefinitely. It's not a power button issue- the button worked just fine before flashing and I've confirmed it still works normally with a multimeter.
I tried to reflash stock using the Google images and "flashall.bat", which says it succeeded- but the phone still loops. I can get into fastboot, but I get the bootloop even in recovery. Running the similar script through Nexus Root Toolkit always fails on flashing the system partition- usually a buffer error due to a sparse header. Can't even seem to get it to do the "fastboot boot TWRP.img" or whatnot. I've flashed KitKat, Lollipop, and MM stock roms to no avail- they all say they succeed, then continue to bootloop.
I've tried just about everything I've seen on here- but not being able to get into recovery hampers efforts like repairing the persist partition.
Help?
When you boot into recovery, the phone reboots itself? If it does, it could be a sign of a failing power button.
When flashing a stock ROM, are you flashing userdata.img and then performing a factory reset/wipe before booting the phone with a stock ROM for the first time?
When I can get into recovery (without a restart), the phone is totally fine.
I think part of the issue is that the battery ran down while I was trying to do the repair- hence it trying to restart and failing. Power button still seems fine (again, confirmed with a multimeter). I left it plugged in to my iPad charger (since that's a 2A charger) overnight and it was still blinking red in the morning. I moved it upstairs and now I can't even make it that far.
Perhaps the battery was just shot by the time I got the "repair" done, hence the boot loops. Is there any way to revive it shy of cutting open the battery + charging manually (with a bench supply) or just replacing the battery altogether? I may try doing a motherboard swap with my working Nexus 5 just to see if it is in fact the battery.
When the phone is powered off and connected to a power source, do you ever see a flashing red LED? You flashed the correct twrp for the hammerhead?
I would try a new battery because it seems like everything is working.
