[Q] HTC Vivid help

Hi,
I recently rooted my htc vivid and i tried to flash a rom. However, the rom didnt work and my phone isnt working. The phone's bottom touch-buttons vibrate when touched, but the screen remains off no matter what i do. What's wrong with it?
EDIT: I got it to boot, however, its stuck on booting, the boot logo just keeps on popping up. What should I do?

any luck?
sounds like you need to try and flash the rom again. this may or may not be a know issue with the rom. check the thread where you got the rom. I had to flash twice with the same rom the last time i did it (unrelated device)
May have to hold the buttons in a specific sequence to get back to the debug mode.
also have a look through this thread:

[Q] Desire S stuck on boot - cant get to recovery

Hi,
I will prefix this (as there are a few people around with this problem who can get into recovery mode) with the fact that holding down Vol- on boot is not getting me to the recovery / bootloader screen.
I have a rooted HTC Desire S (rooted it nearly a year ago, so info about the hboot etc is a distant memory).
Anyhoo, I decided to have a play about with one of the ICS roms but it was a bit buggy and the camera drivers still aren't working for video so I decided to go back to Endymion V3.4 - http://forum.xda-developers.com/showthread.php?t=1310845
I did a full wipe, installed base rom, installed optional addons and then upgraded to 3.4 - booted fine into the OS so set about getting my system set up the way I like it.
I noticed that endy came with a theme installer so clicked on one of them to have a look, it asked for root, said it was installed and would need to reboot to take effect...
SO
the problem is, it now won't boot and is stuck on the white HTC boot screen.
Holding vol+/- and power buttons reset it but it just ends up back hanging on the boot screen.
Have tried pulling battery and trying again.
Holding Volume Down when powering up is no longer doing anything
So, I either need a saviour to point me in the direction of a fix.. or a kindly sould to break it to me gently when they tell me my phone has gone to the USB Dock in the sky..
Any help will be greatly appreciated.
Thanks

update:
After pulling battery again, pulling out sim and sd cards, booting with vol- held down, i got into recovery. Am going to try and flash a different rom after doing a full wipe, I'll update once it's done but any insights in the meanwhile will still be appreciated

Sorted, cleared the thing out, stuck reaper CM rom on it, rebooted and everything is peachy for now.
Thanks me
Curious if anyone knows why this might have happened?

because you didnt flash the addon zip which was released alongside endymon and then tried to use the addons,it does say on the screen do not use these unless you have installed the addons

[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] "working phone", but black screen after the boot logo

Hello guys,
some days ago my phone was permantly booting up in the recovery mode nothing else was possible. As I was on road and couldn't access internet anywhere I just tried to do some wipes, which then made my phone not show anything. I guess the reason that it didn't boot up anymore was that the battery was fully drained. When I was finally back home I was able to charge my phone but then the following happend:
I can start my OPO, see the android logo and then it turns black, but it fully boots up. I mean I can even click the touchscreen and hear some touch reactions/sounds. Also I'm able to turn up/down the volume and hear my phone. Furthermore I'm also able to do the "V-gesture" to turn on the flashlight. When I boot up into fastboot mode I also see the message "fastboot mode" + the little cyanogen face.
All in all everything seems to work, aside that I dont see anything else than dark after the logo.
I tried flashing new roms, stock reset, like seriously anything, but I can't get my phone to work probably again.
Does that mean that my phone got some hardware problems, maybe the touchscreen?
Help is appreciated, thanks in advance!
btw: English isn't my first language, so please excuse any mistakes.

You'll have to try flashing completely stock CM11 rom or CM12 rom, img by img in fastboot..modem, boot, system etc. I helped a friend who had this kind of problem. Probably not the cleanest way, but at least it works.

Already did that 3times using different methods. Stock CM11, CM12 and colorOS

I have a similar problem, did you manage to fix it? And if so, how?
Thanks,
Capelare.

LG G Pad 7.0 V410

Just wanting some advice (if any) to a white line issue I'm having with this tablet. I bought this tablet with Lollipop 5.0.1 already installed. I managed to get it downgraded, rooted, and currently have TWRP installed as well as CM12.1 nightly. The problem I have is that as soon as I install ANY custom recovery (TWRP or CWM recovery) it boots normally at first giving me the LG logo. Then, instead of getting the AT&T logo (or the CM custom boot animation), it gives me a series of white lines spamming from top to bottom of the screen. I know for a fact it has to be software related as when I return to stock KK everything boots fine, giving me the LG logo followed by the AT&T logo. I did NOT use the ADB method. Instead I downgraded using the LG Flash Tool, and a test KDZ file, which allowed me to install Flashify, then TWRP. My problem ONLY begins once I install ANY custom recovery. This process did not unlock my bootloader, however. Could this be my culprit, or would it be something else? Any help is greatly appreciated, and thanks in advance for any help/tips. More information is completely available upon request.
P.S. The white lines eventually disappear when the screen goes to sleep on it's own. I can then press the power button to wake the device which gives me the lock screen as normal. I just want to know if I can get the boot animation working. Everything else works fine.

You found cwm?
