[Q] Can't boot into system- need help

Hi,
My HTC one mini has an unlocked bootloader, TWRP installed and S-off (i don't know if this will help)
I was trying to flash cyanogenmod 11 on my device via TWRP however it said that it had failed. Then when i rebooted my phone it showed the HTC logo but after a couple of seconds, the screen went black. Then the HTC logo popped up again, however, my phone had just booted back into my recovery.
I have tried to solve this by factory reseting however this did nothing, i have flashed a backup i had saved to my computer (that was saved by ROM manager) however there was no change, and i have switched off several times however i always end up in the TWRP recovery. I can boot into the bootloader but from there, i still can't get to the normal system.
This is a big problem as i can't find anything else on the internet that describes this problem and i think that my phone could be bricked. I can't access my apps or anything else. I don't think it is a bootloop as I can't even see the security screen and i don't have the option of entering my password which has happened in the past as it always goes straight to the recovery.
If anyone had any advice on what to do i would really appreciate it as I really need help!
Thanks

Seems you have no os loaded. I'm not sure why your backup does not work. I had an issue flashing cm11 originally, kept failing. Did you wipe data, cache and all and retry your backup again?

[Q] OPO has no OS and Bootloader is Locked

So two days ago my phone started to act up, first it rebooted while I was in the Play Store for no reason then when it rebooted it kept saying "Lockscreen has stopped working" and wouldn't stop doing that. I tried pulling up a backup I made on TWRP (Rooted) but it just did the same thing and wouldn't let me open the settings app when I had the chance. Then I did a Factory Reset but it just made things worse, it booted it up but when I had to choose a language it rebooted and kept doing it. After that I did a full wipe and went I tried to reboot it said I had no OS and now I'm stuck with just TWRP. And I have just found out earlier today that my bootloader is locked. So what could I possibly do? Thank you in advance for those who are able to help.

Yes I have and It does not do anything, I tried unlocking it manually and with a toolkit but no results. Also I have pushed CM11s to the phone and tried to flash it but no luck.

[Completed] [Q] I need help with a Samsung Galaxy Tab 2 10.1 GT-P5113

Hello community, I am new here so I don' t know where to put this.
Well I need some help, I am having problems with my old tab, A Samsung Galaxy Tab 2 10.1 GT-P5113, Flashed with custom ROM CM 10.1.3 for GT-P5110
Worked fine for a year and a Half, the issue that I am having now is that, it constantly restarts, after entering to the OS I can tweak change etc, but after a few secs it just turns of and reboots the system.
The other problem that I am having is that I tried everything that I could think of. I deleted some apps, which came back after the reboot. I booted to safemode, and deleted the last apps that I installed, still came back after the crash reboot.
I went to recovery mode (CWM) and did a Factory reset, delete cache and delete Dalvik Cache. Nothing when reboot everything was like last time.
wen't to and tried to reflash CM 10.1.3 (stable) following every procedure and nothing everything was back.
Last thing I tried is ODIN with stock ROM (which is hard to find for this tab.) but get write error after going to half. I am downloading a second stock ROM (android 4.1.1) to see how it goes.
Hope to find help here, I would be greatly thankful.
EDIT: Flashed now with the new stock ROM, ODIN says success, everything seems fine, but again I got received by the same splash and the same logon screen, and still crashes and reboots...

I really need the help

It keeps with the boot loop.

Hi, thank you for using XDA Assist. After you flash with Odin go into the stock recovery and do a factory reset. If that doesn't work it may be that you're device is just getting old and giving up the ghost. There's a whole forum for your device which may also help. See this,http://forum.xda-developers.com/galaxy-tab-2

Oh, that would be bad news :/
Do you think it could be that I deleted CWM rommanager app, and then accidentally deleted the .recovery, that put me into this situation?

It didn't work. I noticed that after the transferring of odin it doesn't go to the installation procedure. It just skips that and goes to the logscreen with how everything I had.
Now I went to safe mode, and deleted all apps that I could from play store. when I came back after a restart, everything was there, back. :/

Please ask any further questions you have on the q&a forum in your drives forum, the link I gave you. They are the experts on your device

[Q] Stuck in bootloop after Cyanogenmod install error

Hi folks,
This evening I decided to install Cyanogenmod on my Moto G. All seemed to go fine until I started getting "Unfortunately, System UI has stopped" errors that meant I couldn't even get into any of the phone's menus. I tried to reset the phone to reinstall the ROM, but got stuck in a boot-loop where the phone won't boot to allow my PC to see it, so I can't copy the necessary files to it to re-flash the ROM. I also can't push them with ADB for the same reason.
I am stuck! Please offer any advice. Thanks!

did you install a custom theme? does your computer recognize your phone when in recovery?

Just a failed installation of Cyanogenmod. Windows can recognise the phone but gives an error when installing the driver, meaning I can't copy anything to it to re-flash.
On the phone itself, I can get into TWRP in recovery mode, but I don't know how to get files onto it to re-flash.

Nexus 5 not starting

Urgent help reqd
randomly my nexus 5 restarted
google came on screen and now only those four animated circles are showing up and the phone doesnt go further
went in bootloader but cant wipe cache, cant format, or anything else from there.
usb debuggng must be off as far as i remember
trying to flash through sdk manager. have downloaded image. but stops at "waiting for device" in cmd and it doesnt go any further than that. even tried doing it manually through cmd.
when the phone is connected it is showing the drivers but it isnt installng and can see the yellow exclamation.
manually downloaded the drivers and tried installing manually but shows drivers are up to date.
uninstalled driver and reinstalled but same issue. it is connected to usb 2.0.
now how do i get it to work?
I have tried all the options i could search for on this forum but none of them solved my issue.

Is the bootloader unlocked?

How do i check that?

Ok got it
It is locked
How do i unlock?

I checked some unlocking bootloader threads but they all require usb debugging to be on.
My phone is not starting at all so i cannot do that
How do i go about it now

Tried nexus root toolkit. It isnt detecting the device.

Unlocking will wipe you device.
Google themselves have a guide on how to flash, not sure why you are using toolkits.
Also, you will wipe your device, if you haven't already. Make sure you have the right drivers, make sure you get the device to come up under "fastboot devices"

Already tried all methods mentioned by google or xda.
If you read my initial post my phone is not getting detected as well but shows installing drivers when connected but the installation fails.

Manually install the correct drivers.

Tried that but i get the error that you already have latest drivers. But its not detecting the phone

Try removing the drivers and reinstalling
Also, try different USB ports and cables.

Did all of that a number of times. Still no luck

Other phones are getting connected and detected just fine.

Hi all, i have a similar problem
this morning my n5 boots into "optimizing apps", but stops when reach around 15/20 apps and reboot (3 or 4 times)...
Now, only keeps in android animation like useruser12.
I can see my data in TWRP, battery 95%...
I wipe cache/dalvik... nothing
I reflash the kernel (ElementalX 6.17), still nothing
Any ideas?
PS: latest news. After make a backup, I made a factory reset and restore a system-boot-cache partition from old backup. Now the phone boots but i hate lose all my data xD. I want try to solve my problem using my "corrupted" backup for avoid losing data. If that fails, I can always restore this functional backup. Any ideas again?

Used the nexus root toolkit.managed to unlock bootloader but immediately the device reboots and goes into the bootloop again.
Tried the flash stock + unroot function as well which detected my factory image and everything went smooth till it came back to unlocking the bootloader and rebooting the device after that and again went into the bootloop
Though i have installed the drivers, on reboot windows 7 automatically starts installing the mtp usb device driver but fails. Manually downloaded the drivers and installed as well.
Still its not worked and whatever i do it comes back and get stuck at the bootloop.
Any expert can give a solution? Thanks

After unlocking the bootloader, does the bootloader relock when the phone is rebooted? If it does, the memory chip is defective.

Phone doesnt reboot completely.goes into a loop after the google logo and doesnt go further.
If i switch off the phone midway here without it booting up and then restart the bootloader then its locked again.
But what i read was that the process of complete reboot needs to finish and i need to turn on usb debugging. So is it because of that the bootloader locks again?
Anyways, this what im facing

Lucky that you could do a factory reset. I wasnt even able to do that from the bootloader.

Sorry, i did it via TWRP.

If the bootloader relocks itself upon reboot, it's the memory chip that is damaged.
