[Q] Help / Stuck [D800] - Can't get computers to see phone in Download Mode

I've probably used the LG Flash Tool 10 times the past week on both my home and work computer with no problems. Last night I flashed the KK bootloader and a stock 5.0.2 ROM (after tot'ing back to 4.4.2, rooting, etc).
It hangs at the LG logo and that's where I'm stuck. I tried going into Download Mode, but suddenly both of my computers won't see the phone and give me an error in Device Manager. I've tried uninstalling / reinstalling the drivers as well. Why in the world would that happen unless somehow Download Mode was corrupted, possibly? But it goes into Download Mode fine, and appears to look right...
I've tried getting into recovery but can't. When it should load up TWRP (after telling the G2's "stock" recovery screen I do want to reset), I get the green spinning Android (not the red exclamation) for a second, then it tries to boot up.

}
Any advice would be appreciated as I've never run into this before.

So when the green Android popped up, I tried to hit a combination of the volume and power keys and WAS able to get into recovery. Unfortunately, it appears, somehow, TWRP was overwritten by the stock recovery. I have no idea how that could've happened. Or does stock recovery technically stay in place since this is "loki'd" and not actually unlocked? And if so, is there some way to get back to TWRP that I'm unaware of?

To add to the weirdness, when I plug it in to charge, it doesn't pull up the battery like it usually does when powered off, it just tries to boot up again...
If I could just get the computers to recognize it again...

Installing the LG PC Suite got my drivers to a point where it could recognize it while in Download Mode. MTP still didn't work, but that didn't matter for Download Mode. Not sure what happened, but at least I was able to flash it back again.

ASUS ZE550KL - My phone is the god to failure =]

Hello everyone,
First of all, I apologize if this post is in the wrong section. Also I'd like to say how awesome it is everyone that is involved in these projects.
My Issue is I can't get ANYTHING to work, I have tried so many roms that apparently work for my phone and I always, foot errors, signature errors though the adb. I have tried every program to unlock bootloader but apparently does not work unless you are running V2 551 2.40.*.* so I went and downloaded this, and wants again can't flash the ROM. The unlock bootloader was weird, I went through all the installation and I don't even know if it worked to be honest. I can boot into the phone via power and volume down, and get a menu that includes, apply apps from ADB, wipe/restore phone, fastboot mode * which goes as far as my phone saying *FASTBOOT !!!* then thats it will not continue. The power and volume up does the same thing. So basically I'm starting to think this piece of crap phone will never have a decent operating system on it. The phone is in developer mode and USB debugging is on also. * Basically have done every single tutorial I can find and nothing works*. Also the twrp doesn't even work. I have even tried flashing back to an older version on the phone and get the same ADB errors. I have installed all the ADB and also minimal adb and fastboot and all drivers for the phone as well. * TRYING NOT TO MISS ANYTHING*
My phone specs:
Model: ASUS_z00LD
Android: 5.0.2
Baseband Version: 202c10_10.0.0_160120
Kernel: 3.10.49-gec27b65

Hope it works
Did you try to unlock bootloader the official way? I myself unlocked the ZE550kl following this thread http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263
You can check if bootloader is lock or not from fastboot by entering "adb>fastboot oem device-info" should show up somewhere between the lines "Device unlocked: true"
After unlock only then you can install Official recovery TWRP 3.0.0-0 from here http://forum.xda-developers.com/zen...recovery-twrp-3-0-0-0-touch-recovery-t3317513 .
If needed TWRP will also help you root your phone once is installed.
Good luck!

so i destroyed my 6t for good.

so i took some break from android for couple of years and it seems somethings have changed since then, i had oneplusone so rooting wasn't new to me, but i got my oneplus 6t rooted it straightaway i had some issues with TWRP not sticking after i flash and had some issues were i couldn't find the directory to install roms but all that was fixed, had some other isues with using my banking app but that was sorted a swell so i was having fun.
a mouth or so ago i was wanting to get rom and my TWRP wasn't there it kept rebooting into fastboot menu, so i tried to flash TWRP again and it wasn't working so i messed up with boot img with all sorts of command lines related to flashing boot img, now my phone is dead for good i don't see how it can be fixed when the boot is corrupted i cant even boot into fastboot.
when i tired to boot into fastboot it wont work it stuck in that unlocked bootloader screen i have tried every combination available and it reboots into that. please help if you can.
please if i didn't explain my self properly ask away i just forgot what i did it been a while.

Try MSM tool

As mentioned, neither Fastboot or recovery need to work for the MSMTool to work.
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Note the screen wont do anything, the phone will just be recognized by the MSMTool.

Click to expand...
Click to collapse
you guys have no idea how great full i am its finally working from dead phone in the storage to daily driver.. again you can always rely on xda members.

Yeah, OnePlus is one of the only phones that is truly un-brickable. Even Google pixels do not have working MSM tool.

S8 bricked / stuck in recovery mode, what did I do?

Hi,
first of all: I'm a noob and I've got no idea what I did. I appreciate all of your help to get my phone back alive!
My phone (Samsung Galaxy S8, SM-G950F, stock ROM, Android 9.0, not rooted or anything else) is stuck in recovery mode. It doesn't react to any buttons (e.g. very-long-press power button) or connecting a USB cable, also my PC and Odin with all drivers installed won't recognise the device.
What I did: I went into download mode to check if I could find my RMM status (I didn't) and navigated to "view recovery logs". I entered /cache/recovery/last_log and scrolled through it until I reached "back". I confirmed with the power button and - then I can't really remember what was there on the screen - I got into a similar log screen. It took a while and I pressed the Vol-down key quickly numerous times.
Then it happened: there was a screen with some options to choose from (written in blue) but spamming the button I probably entered something. Another log (or whatever) showed up --> see photos. It took about 20-30 minutes to reach 100% and then went back to the Android recovery screen, where it's been stuck for about an hour now. I tried cancelling it numerous times times with long-pressing power button, but nothing happened.

PLEASE help, is there anything I can do besides waiting for the battery to die and reboot?
Big thanks in advance!

Note: the device has been factory reset recently with no data on it, OEM unlocking and USB debugging were checked in developer options as I was about to flash TWRP.

1)Download stock firmware from sammobile or else (exact your device and model)
2) Download Odin
3)See video on youtube if noob(obviously ) to flash stock by going to download mode
After successful installation u will have your cell back
Cheers......

Thanks for the advice, but I found that pressing Power + Volume Down for 20+ sec. could eventually shut down the phone. After that it rebooted into recovery mode, even though it took ages.
Now I'm a happy owner of a LineageOS S8 btw
Entering download mode wouldn't have been possible at the stage I described in my first post, as the device didn't react to anything at all.

[HELP] Bricked PX5 HZC, can't open recovery.

Hey y'all. I tried updating my PX5 (I had the latest HZC mcu installed) 6.0.1 to android 8.0 using this guide
After booting into recovery, I tried to select the update.img file through the SD card but nothing happened.
After nearly giving up, I decided to try the same thing using USB drive. I was able to select the img file, they screen showed a few lines of text and just instantly turned off.
I tried to boot it, enter recovery mode or what not but nothing happened.
If I hold the RST button for 10s~ the non-phsyical side buttons blink for 5s, but nothing happens. I was not able to return back to the recovery mode.
Is there anything to do to solve this? My PX5 has 1 USB slot and 1 TF slot. I assume it does not have GPS sd slot so that's why the file could not be read, and either I had a corrupted file on my USB drive or it's just impossible to do through USB and it bricked my device.
I would appreciate any help with solving this brick, It was a mistake trying to upgrade from the first place..
If there is nothing to do, i'll just go and buy a new head unit, I wanted to upgrade because it lacked some features and the UI was very simple and outdated.
I don't have a photo of the MCU, but i had the MTCE_HZC_2.94b installed from here: https://disk.yandex.ru/d/umCvHqCDzHccr
I also downloaded the update files from here, following the guide above.
Before updating the MCU, I had the MTCE_HZC_2.74 installed by stock. The MCU update worked well, the android upgrade failed utterly.
Now the unit won't turn on at all and there is a black screen. long pressing the RST button until the side buttons blink does not boot the device into recovery. seems like even recovery got corrupted somehow.
After some research, I found out that I can use OTG cable to flash the firmware and recovery using a PC.
Will I be able to flash android 8-10 directly instead of flashing the android 6? or I'd have to flash directly android 6?
If so, where can I get the frimware/img file i'll need to flash?
EDIT:
I tried to connect the system to a laptop using USB A to A cable but the rockchip tool did not recognize it..
any other ways or the unit is lost?
