bricked or not bricked

hi guys, following this giude ( http://forum.xda-developers.com/showthread.php?p=20365299#post20365299) now, my dhd won't start. After flashing in bootloader mode, pd98img, phone ask to me to restart, then 3 minutes of vibration before start. I decided then, after booting, to install update proposed by HTC in software update;then the phone locks in the update screen without moving forward.What can I do now?tnxx.... can't access to bootloader

I'm not really clear on what you were trying to do here... You've gone through the process of downgrading to an older software version (seemingly successfully), then as soon as you've booted you've tried to upgrade back to where you were before you started?
Have you tried pulling the battery and then trying to boot into bootloader? Does adb recognise the device?

[REQ] Help: bootloop after 7.1.1 beta OTA and cannot enter recovery mode

I've been watching several threads for the last few days, and have not seen this exact issue. I would greatly appreciate some help.
Device:
- Nexus 5X LGH790 32GB
- Stock bootloader / fastboot
- Never unlocked / rooted / etc.
The only advanced thing I've done is join the beta program a few months ago to get 7.0 early. Got that without any issue.
Issue:
I received the 7.1.1 OTA on the day it came out. Installed with no problems. The next day, the phone just froze in the middle of regular use. After about 15 seconds, it started boot looping to the Google splash screen. I can hold volume-down to enter fastboot, but when I select recovery mode, it just starts looping again. Pretty much all I could do was power it off. I did find out by accident that if I left it looping for long enough, sometimes it actually loaded normally (I even saw beta program warning/notice). But when I tried using it for more than a minute, it would freeze, reboot, and loop again.
What I've already tried:
- I tried using the WugFresh NRT fix softbrick method. I was able to quickly turn on debugging one of the times that I left it to loop. But when NRT sent a reboot the phone, it threw it back into the loop and NRT stopped recognizing the device.
- I tried to follow the unbrick procedure using a TOT file in this thread: http://forum.xda-developers.com/nexus-5x/help/tutorial-how-unbricked-nexus-5x-16gb-t3481766 But even after using LGUP, I still cannot even get into recovery mode.
- I filed a bug in the AOSP here: https://code.google.com/p/android/issues/detail?id=225802.
I'm at a loss here. On another thread, a member suggested this type of loop was a hardware/solder joint issue. I suppose that's possible... but man, what a coincidence that would be! Just now after the OTA the hardware fails? Any other thoughts? I'm pretty new to a lot of the terms/methods here, so maybe I missed something.
Thanks, DCK.

Update: I tried using LGUP again. The phone still gets stuck on the Google screen then boot loops.
Now, however, I am able to get into recovery mode consistently. Other threads have suggested doing an OTA sideload at this point. But I cannot seem to get my device recognized. The NRT shows no ADB devices connected. So I'm still stuck. Is there another way to try sideload?

Try fastboot/bootloader mode and fastboot flash the OTA manually.

Update 2: Seems like all the other things I tried over the last few days have caused various unofficial USB drivers to be installed. I've tried uninstalling most of them. I downloaded the google USB driver from latest SDK. But my 5X is still recognized as a Kedacom device when it is sitting at FastBoot.
However, I must have made some progress because I was able to start the sideload process. Unfortunately, I am now stuck on yet another error. The phone hangs at "verifying update package" and then after about 2 minutes... it reboots itself and starts looping again!
I thought I had it. So close. Now I want to throw the phone. Going to sleep, but would be grateful for any other suggestions in the morning.

use nrt to erase all partitions, then download 7.1 factory image, unzip and flash one by one the partitions.

Sounds like the boot loop issue many people have been having (the hardware/solder issue). It happened to me a few weeks ago after upgrading to Android 7.0. I got a replacement device from google.

If you're bootloader is locked, NRT or any other method to flash the factory image is not going to work. The only suggestion I have is to un-enroll in the beta program and hope your device will boot long enough to flash the ota Google will send the device to get back to 7.0. Note, this will wipe your device.

Same problem here. It can't be recognized after I reboot to fastboot. So I can't flash anything.

If the device isn't recognized try this http://forum.xda-developers.com/showpost.php?p=69273414&postcount=33. It's worked for a few of us with the same problem

Enter stock recovery then flash the full ota via adb sideload

Soft/Hard brick when chainfire rooting

Hi there,
Proud owner of a new Pixel XL. Unlocked version. Tried rooting last night (i've rooted all devices i've owned and am not new to this). Followed the instructions to a "t". The device won't get past the white screen and dots leapfrogging each other. Now when going back to fastboot, device isn't recognised by ADB Fastboot etc...
Please help!!!!

My guide should be able to help you get back to the OS and then install root.
Keep in mind you may lose data if you don't remove the -w from the script mentioned in the guide.

Did you unlock bootloader?
Then immediately try rooting?
That is one cause for bouncing dots.
You should: flash factory image, then boot into device before any flashing. Setup device until you are at the home screen and OS settled. Use a pattern or pin security. That is needed to make recovery work properly. You need to decrypt at recovery boot. No ask for pin? Then power off and boot TWRP again.
Follow directions in TWRP and SuperSU threads to a Capital "T"...
Versions:
Latest "Q" firmware
Boot TWRP RC1 img, then flash zip installer
Use SuperSU 2.79 SR1.
You'll have no bootloop. I found first rooted boot to take just a few minutes.
Just in case: update SDK platform tools if you haven't cos that screws people up for days too.

Thanks mate. But i get to step 9 and nothing happens. My device is no longer recognised

thanks mate, but the problem is that now the device is simply not recognised by my computer. I can't flash anything

I should clarify.
SDK is 100% up to date.
I am trying on both Windows 10 and Mac.
Device drivers worked fine prior to trying to root.
I'm really worried that i might have just bricked a $1.4k(aud) device

I unlocked my bootloader and got a bootloop when I tried to fastboot to root. Would not recognize the device either. I redownloaded SU 3 as suggested in the third post and it worked. Good Luck.
I used the fastboot to root method and did not install TWRP.

Thanks, Mike01680. trying now

When i go into sideload i can see the device listed on adb devices!

Okay. Booted into recovery, found my firmware for NMF26O. Downloaded and ADB Sideloaded it can once again boot. thanks for all of your help!!!

Bootloader unlock bootloop on 2.0

Hey guys,
So I was able to return my HW to a normal state on AW 2.0. It turns out as soon as I unlock the bootloader, it goes into a bootanimation bootloop (a few times, it displayed an error then finally booted AW). And I can't get into the stock recovery. It seems like this one is screwed up somehow. Flashing TWRP works though.
I really don't understand this. I thought this was supposed to be like a Nexus/Pixel device. Has anyone else experienced this behavior? I would really like to unlock it and flash Negalite ROM.
Thanks!
Edit: OK so the watch only works if I flash the custom ROM from AW 1.5 using TWRP. It goes all the way and doesn't bootloop. SO WEIRD.
---------------
Original post:
Hi everyone,
I got my HW today and it's already messed up! I've been flashing ROMs and such for a long time now but I'm stomped. Initially, I wanted to install Negalite ROM.
Here's what happened:
- I used my watch for a bit on 1.5, connected it to my phone, did the initial setup and OTA updated to 2.0.
- I decided to unlock the bootloader. Worked but watch got stuck on a recovery bootloop (with the open bugdroid). Managed to get rid of it by factory resetting through TWRP (which I fastbooted).
- Watch was restarting (on 2.0) but got stuck on another bootloop (on Nougat bootanimation). Sat there for about 20 min.
- I decided to downgrade to 1.5. Used fastboot to flash boot.img, recovery.img and system.img. The system.img gave me an error at first while flashing but proceeded all the way (9 steps out of 9) with success (?)
- Now the watch is still stuck on bootanimation (I think it's the MM one, with the flying around dots) and won't go any farther.
Note: I can get into fastboot and TWRP 3.0.3 is installed. But multiple factory resets from TWRP don't change anything. I can't adb push anything to the watch from TWRP either (I tried the ADB sideload option). ADB drivers should be OK on my Windows 7 x64 machine (I used Google drivers from the SDK).
Any HELP please? I really don't know what to do now since I can't push any file to the watch... and I've read many threads on here to no avail.
Thanks in advance.
edit: IT BOOTED! I used a different system.img (the one from sturgeon-m6e69f-factory-e659286a.tgz) and flashed it with fastboot and IT WORKED! Thanks to whoever posted this version! Now I will try again to install Negalite.

"Error occurred while updating..." Think I have bricked while attempting to downgrade

"Error occurred while updating..." Think I have bricked while attempting to downgrade
Please help.
I was attempting to root and SIM unlock the SM-G925T. It was already on Nougat 7.0 (and November 2017 security/patch).
CF Auto Root would not work. Neither did an attempt to manually flash TWRP (although attempting one of those two tripped KNOX).
I thought I'd downgrade to Marshmallow and then re-attempt root/unlock. Downloaded "G925TUVU5EQC2" from gsm-firmware and tried to execute via Odin.
I am left with a permanent blue screen with that "!" reading I need to use Smart Switch's Emergency Recovery. That, btw, does not work either (and neither does re-attempting after reinstalling device drivers from within SS).
Could someone please suggest what I should do? Pressing and holding power/home/vol- keeps taking me back to this blue screen. Unable to get to the recovery or anywhere for that matter.

Ok, so... Despite not seeing any other screen, I went ahead with reflashing the Marshmallow ROM via ODIN. Worked this time and the phone rebooted.
Interestingly, now, my unlock request was approved by the Device Unlock software (didn't need to use other means). However, I am stuck on Marshmallow and the device won't update to Nougat (get the error "phone not registered", despite it being unlocked). Hilarious. But at least the phone is functioning now.

Followed the same ODIN method and flashed the latest 7.0 image (Nov 2017 patch). Thankfully, it retained the unlock. Not sure if it can upgrade (I don't see the "not registered" error) but I won't know till there is a release.
Briefly got an annoying "com.sec.vsimservice stopped working" error - booted into Android recovery, wiped cache and did a factory reset. Working now!
Had already tried rooting this version (using both CF Auto Root and TWRP), but in vain, so not harbouring hopes now. Will get back to it later.
