Help? Bootloop and can't access bootloader

Hi there,
I recently installed ARHD 9.0 on my One-X but didn't like it, so i tried to revert to CM10 and now i think i've screwed things up. I rebooted, ran CWM, did a full wipe, cleared the cache and dalvik cache, installed CM10, installed GApps and tried to reboot and flash the CM10 boot.img - however instead of booting back into the bootloader the phone just continued booting and is still at the CM10 boot screen. I can't access bootloader for some reason - i hold down power and volume down, but no bootloader. Is my phone bricked? What can i do?
Appreciate any help. Thanks.

I've no idea. I managed to get into the boot loader eventually - It just took multiple attempts! I was sweating bullets for a while there

How did you manage to fix it? I got into bootloader but everytime i try to get into recovery i get the same bootloop again.

How did you find yourself in that position to begin with? Was it flashing a new rom? Did you flash the boot.img? Don't panic, so long as you have access to the bootloader, you will be ok.

Fastboot erase cache

[Q] Can't boot up my DHD

I was going to flash a new ROM on my DHD and did the usual steps: backup using TB, reboot to recovery, factory reset and then go find zip to install on SDCARD. But this time instead of finding my zips I had already transferred, I found none. So I mounted the SDCARD through the recovery menu and transferred the zip using my laptop.
I still couldn't see the zips, so I chose to reboot the phone from the recovery menu. Booted into old ROM, completed the setup wizard and rebooted to recovery again. Still no zips! So I turned the phone off and was just going to boot straight to recovery using VOL UP and POWER but then I only got three short vibrations and nothing happened, so I booted again to ROM and rebooted to recovery from there.
This time nothing happend, nothing at all. And now I'm stuck where I cant boot it, not to recovery, not to HBOOT and not to ROM. Tried taking out the battery and putting it back in. Tried turning it on using just POWER, using VOL UP and POWER, using VOL DOWN and POWER - and in different time length combinations. adb reboot bootloader cant find the phone. The LED doesn't light up when plugged to USB.
ROM: JELLYTIME for DHD/Inspire4g - 4.2.2 R4
Recovery: ClockworkMod
I'm guessing my DHD is completely bricked, right?

Oh dear poor you, I'm no expert, but unless your battery is dead, I'd say you killed your phone. Can't even get into recovery yikes.

If your battery is dead you may need to ask a friend to charge it for you? If your phone still boots into recovery you havent killed your phone, if you go to the htc web site & look for the correct software for your phone you may have to apply that to reboot your phone again, but after you will need to root again? But first try another rom a stable one & try doing this - factory reset/full wipe, then wipe cache, then wipe dev cache, then fash the new rom. Hope this helps

Help, soft bricked my device.

I was attempting to unlock/root and long story short, now I have TWRP installed, and I can get to FASTBOOT but if i try to boot normally I get the Nexus logo, and no further. When I unlocked, I installed TWRP then loaded it. After leaving TWRP it said 'Seems you are not rooted, want to root"? or something to that effect. I clicked YES and now I'm stuck. Since I had just unlocked it, it *should* have reset my entire device(which was all stock anyway) so I am not sure what went wrong. I have been trying everything I know but I'm now out of ideas. Would appreciate any help. I see now that the version of SuperSu that it would have pushed would have been wrong, would that be preventing the tablet from booting?

If you can mount in fastboot you're not bricked. You tried to check md5 and push the recovery image again? And also try to throw new ROM on it.

It wont boot so I don't know how to put anything on it, it's empty and doesn't show up in windows. Also I don't know what you meant exactly by push the recovery image again. Twrp is working fine. Sorry I am hardly a pro at this stuff.

Try to get to fastboot and connect PC and check if it connects. You will need the USB drivers installed

Oh I can do that no problem, been using ADB. But now it just won't boot normally. But I can use the terminal and everything.

Then it should be possible to flash and push recovery and ROM to device even get a stock image back.
Which recovery image did you install?
And did you flash any ROM or kernel?

I would suggest you just restore your N7 back to stock. No need for root yet, seriously! But this should help get you going in the right direction.
Power it off completely. Hold Power + Volume down until it boots into the bootloader. Run the following commands:
fastboot devices (to confirm you are connected)
fastboot flash recovery recovery.img
If you haven't unlocked your N7 yet, run fastboot oem unlock first.

I put TWRP on there, immediately after unlocking. So it should have been completely stock since as far as I know it wipes it when you unlock. After putting TWRP on there, i told it to reboot normally(from within TWRP) and it detected that I was not rooted and asked me if I wanted to install SuperSu. I said yes and now it will not boot to the operating system. It boots fine to Bootloader and Recovery. And I am certain it's connected to my PC because I can even tell it ADB REBOOT BOOTLOADER/RECOVERY and that works. But I don't see how I can load a ROM onto it if I can't access it via windows. I don't know how to get a ROM onto the SD card. Surely there could be a way but I don't know it.

Start over by downloading recovery, Superuser and a clean stock rom image.
But before that you could try to reset all data in recovery (factory reset) and cache if you haven't tried.

Thanks to this thread I have booted! Still have to root it but now that I know that you have to flash the NEW SuperSu not the one TWRP flashed for me, I shouldn't have a problem Thanks so much for your help everyone!

Phone stuck in boot loop

Hello guys,
So basically my phone shut down while I was using the app drawer. And it got into a boot loop. The phone is rooted, and it has Lean Kernel and Paranoid Android 3.6 installed on it. It tried to factory reset, wipe data, wipe cache, basically do everything in the recovery mode, but it still wouldn't boot. So then I formatted the sd card, and everything else there was to format. And now the phone is just stuck on the word Google. I understand (guess) that's because I've formatted the internal memory. How do I get to flash a rom to the phone now? The computer can't seem to get a connection via USB while the phone is stuck on the word Google. Thanks for your help

Just ran in to the exact same problem on my girlfriend's phone. Please help. It turns on and I can get into bootloader mode and recovery but when I go to reboot, it just stays on Google startup screen. I did the same things, formatting and such. The sd card is empty with nothing to flash. Help!

Ok, so I've managed to flash another rom. But it only shows me the boot animation and back to the Google logo...

I tried installing this kernel and this rom. But it still doesn't boot up. It seems that the kernel is installed on the phone, but the rom isn't, because the command line on the phone doesn't actually write Done or anything else, it just sits there for a while doing nothing.

why dont you flash back to stock using fastboot?

Been there and the "Nexus Root Toolkit" by WugFresh really came in handy. Used the software to go back to stock and since then no problem

Via fastboot flash the recovery first and restore from there
and then see..
it should boot up..
or
just flash a stock rom too then.
check the link for stock kernel

Ok, so I'm trying the Nexus Root Toolkit right now to get back to stock. But the log shows that archive does not contain:'boot.sig' , 'archive.sig', and 'system.sig'. The process was finished, and it says that stock was isntalled on the phone, but it still stuck in boot loop. It says in the CMD that it might be stuck in boot loop for 5-10 minutes, but it will eventually boot. But the phone still doesn't. And I've also tried to install each .img file through fastboot using this guide. But it still seems to be stuck in bootloop. I've been waiting for 5 minutes, but I'll keep it on for longer...
Update:
Ok, once it showed that :"apps are updating x out of y" and then it started looping again, and then another time it booted until the place where I could choose my language, aaaand it started looping again.

Well that is a progress
Try to update the recovery using Nexus Root Toolkit. Push the stock ROM using the advanced option and then flash the stock again using recovery. Wipe cache and dalvik cache then reboot.

try to lock your bootloader. if its still unlocked after you reboot your phone, your emmc chip is fried.

Having the bootloop. I've tried the Universal Nexus Tool for Linux and get no boot SIG and recovery SIG error.
I can't get it to boot at all. :/

I locked it with "fastboot oem lock" and after taking out the battery it says that the bootloader is locked. So I guess the emmc chip is fine?
By the way, is emmc memory related in anyway to the Lagfix(fstrim) app that I've got from Google Play to speed up my Nexus? Maybe the problem is somewhere there?
Also, If I'd locked the bootloader and took it to the Sprint store, would they try to fix it even though I had the phone for more than a year?

I've tried everything and still a bootloop. No matter if I recover to stock or flash a custom ROM.

Stuck in TRWP

I went back to my backup and it was fine but then my phone said something about an update and I did it. While the phone was rebooting it went back to TWRP. No matter what do it always goes back to TWRP. I even wipe ans restore and still nothing. There's a little picture in between the home button and the back button and when I touch it it says "updating partition details.......full SELinux support is present" I dont know what this means. Can somebody help me?

I really need some help. Don't know what to do.

Thank you. I did it the first time and it didn't work. I cleaned and flashed a rom and then went in and did the steps, now its booting and installing the rom. I'm going to unroot and just leave it the way it with the stock.
