After Kernel-Flash Bootloop and no Access to Bootloader or Recovery

Hey,
Ive got a big Problem.
Ive flashed my HOX with the Insert Coin Rom 10.7.1. Everything worked well.
But then i wanted to flash another kernel to get access to the cpu core clocking.
i wanted to flash franco kernel r21. so i downloaded the kernel and the modules and did the step-by-step tutorial.
but something went wrong. after the reboot my HOX has a bootloop. and i cant get into the bootloader. it just shows the htc logo.
when i connect the HOX with usb to my PC it makes the "something plugged in"-sound on my computer ^^. but nothing happens. When i try to power off the HOX it just restarts. it is on as long as the battery has capacity.
Could i do anything to get it back to life?
Sorry for my bad English.

Try issuing from pc
Fastboot erase cache
Fastboot reboot-bootloader
if you want to go to bootloader or
Fastboot reboot
to reboot into your rom.

the problem is:
fastboot just shows:
"waiting for device"

Try holding down power button+Vol down button for approx. 10 seconds. That should take you to bootloader.

Then plug the cable in. Go to fastboot. You should see fastboot usb on the phone.

now ivegot a bigger problem. after flashing a newer version of insertcoin (13.0.0) i updated hboot to 1.31, i had no network connection anymore. then i wanted to flash the stock kernel but now it restarts again and again and shows me for about 2 minutes a black screen with a blue screen phone and a red triangle with a red "!" in it.
i think i did nothing good. :/

he was wrong. You have to wait for it OTA refreshing

what means OTA Refresh?

Custom kernels don't work on the new base for your information.

ok. so how i can flash the stock kernel? i cant get into fastboot mode, because it just shows the warning sign i told you above.

Do a battery pull..leave out for half a min...put battery back in and hold power and volume down til device boots into boot loader. If it doesn't boot to boot loader,then its bricked. If you can access BL,its not bricked

Nope. Believe me when i say no. There is a program called QPST, made by Qualcomm which is able to detect the DHD in this state. But we dont have the necessary files for resurecting the phone.
Those files are only available to Qualcomm devs. I searched high and low for the files but got nothing. We started a thread for it somewhere in the Q&A Section.
To Shed some light on your problem, There are two things that can cause your device to end up in this state.
1. Either you have a corrupt bootloader, radio
2. Fried or burnt emmc chip or emmc controller.
My suggestions are you can send the phone out for JTAG repairs.(They would short circuit the motherboard and reflash your bootloader...that is if its a curropted bootloader or radio fault).
Or you could you could find another DHD with a cracked screen on ebay. SInce the screen is cracked, the price would be low.
All you would have to do is swap the DHD with the cracked screens motherboard with yours and voila!!

LG G4 H815 - Stuck on Bootloader State

Hi to all,
yesterday I attempted to install LineageOS on my LG G4 h815.
I followed this tutorial -> https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Everything went fine. I was able to boot under LineageOS reinstall my apps etc, etc.
This morning when I woke up everything seemed normal too. But, few minutes ago, I sent an SMS via Google Messages the phone froze and then black screen.
When it froze I had 97% battery.
Ï tried to reboot it with power button -> Nothing.
I tried to remove the battery put it back on and pressed the power button -> One tiny vibration but nothing
I tried several times the same last process and finally I managed to get the screen with "Bootloader state : Unlocked !", but I cannot go further.
If I connect the phone with a USB cable, wether he's "turned on" or turned off no led is blinking.
Does someone have a clue to fix this or has ever encountered this issue ?
Tanks in advance and do not hesitate to refer to an old post. I wil check (but found no same case).

Just to perfectly understand.
Are you advising me to flash my recovery with an older version via my laptop (I imagine via adb/fastboot) despite I can't even get my LG be recognized by my laptop ?
Will the adb/fastboot command be functional as the LG seems not to be recognized on the PC?

The best way to get your laptop I recognize your phone is to get LG up running then with the usb plugged n drop the battery out then put battery back in then close off LG up.
Then start it again and when it go's into download mode the pull usb and close off LG up Then plug it back in with dos prompt open............

LG UP had no effect on the phone.
However, now the phone seems to have 0% battery and when I try to boot it I get the graphics to plug the phone on a source of energy. Once I do that the front led is blinking in orange (I guess because I had less than 1 or 2% o battery) and now the front led is still lit on in orange. Is this a good news or I'm hoping for nothing.
Anyway tomorrow I will try to get it back to my retailer.
Does anyone succedeed to get it replaced by LG even if the bootloader is unlocked ?
Thanks.

After a little journey to the repair shop of my retailer everything seems to work correctly, for the moment, with LineageOS !
Thanks everyone for your help !

Redmi Note 5 Pro dead, no fastboot, no recovery, no led

Hi all,
after waiting 15 days, I have unlocked the bootloader, flashed twrp, firmware and rom, then rebooted.
the phone is dead ever since.
I can see it in device manager as "Qualcomm HS-USB QDLoader 9008 (COM10)", but I am not able to flash a rom through miflash.
any help is welcome
*additional informations*
here are the steps i followed:
1) unlocked bootloader succesfully
2) flashed official twrp
3) wiped EVERYTHING except sd ext
4) flashed this firmware
https://sourceforge.net/projects/xiaomi-firmware-updater/files/Developer/
5) flashed this rom
https://forum.xda-developers.com/re...ment/ota-resurrection-remix-os-6-0-0-t3777375
6) rebooted, dead
I noticed now that if i try to turn on the phone, the led blinks a few times
PROBLEM SOLVED:
the phone is alive again. Here is what I have done-
1) I opened the phone and tried the test point method, but I noticed that nothing changed in the way the phone was detected by my laptop. So, it's not crucial have "COM 7" in device manager.
Then I basically followed the steps suggested by @Destrangis in post #3
2- In MiFlash Choose CLEAN ALL and install this rom: http://bigota.d.miui.com/V9.2.7.0.NE...179eb04f38.tgz
3- Installed TWRP, WIPES and flash https://androidfilehost.com/?fid=5862345805528041092 and Magisk
4- Come back TWRP, WIPES and install your favorite rom.

EDL booting and flashing is your solution.
Now, only debatable is will you use EDL booting procedure which requires opening of the phone to short two contacts to be able to boot in EDL or You will use altered ADB which gives possibility to boot in EDL without case opening. This second option is somehow questionable but first, i think, if second option to enter EDL without opening is way to go!

Hard brick. I went through it. Follow these steps: https://www.youtube.com/watch?v=lfkRHAW2iXI .
1- You have to activate the EDL mode.
2- In MiFlash Choose CLEAN ALL and install this rom: http://bigota.d.miui.com/V9.2.7.0.N...EK_20180406.0000.00_7.1_global_179eb04f38.tgz

4- Come back TWRP, WIPES and install your favorite rom. :good:
PD: If you see "COM7" in MIFLASH, go directly to step 2.

Try to use usb 2.0 ports.
Maybe edl mode has timed out. Press the power button for 20-30 seconds to power cycle the phone.
Or open it up and remove battery pin for a minute. Reconnect and try again.

I already tried on usb ports 2 and 3, and it did not work. Holding the buttons for a long time did not solve either. I opened it to test point, removed the battery, but none of it makes the phone work. The problem is that at the time of fash in Miflash it gives the following error: CAN NOT READ HELLO POCKET.

After uninstalling Magisk: Stuck at No command

Hi there,
I am having troubles with my phone (LMG810EAW) after uninstalling Magisk per app. The phone was Magisk-rooted and the bootloader is unlocked.
It constantly repeats rebooting, telling me that my bootloader is unlocked and then just showing the "No command"-Screen.
I do not have ADB-connection and the device is not recognized as USB device by Win10 at all.
None of the Vol+/Vol-/PWR combinations worked.
Except I can go into bootloader with VOL- & PWR and shortly releasing PWR at LG logo. But there it only shows the "Factory Reset" options.
Is there any option I can debrick my phone?
Thanks!
Best regards,
LeFish

I just got into fastboot-mode by fiddling arround with the phone!!!
Maybe this helps other to debrick their phone:
*The phone was plugged into USB of the computer.
*I pressed Vol- & PWR while on "No command"-screen
*The screen turned off
*Instantaniously, I released PWR, kept holding Vol-
Suddenly I was in fastboot-mode and the phone was recognized in CMD/fastboot.
Trying to get on from there - I'll keep reporting.
Best regards

Just extract your boot IMG from your kdz and fastboot flash it. What's your reason for unrooting? If you want safety net to pass without magisk hide, you'll also need to relock bootloader

Or just flash the magisk patched boot again for now

With holding Vol+ & Lock Button and then at the LG logo releasing the Lock Button, I managed to get into the Download-Mode.
I then installed LGup-LAB-Edition. Afterwards I could flash the stock 10r ROM. Everything is working now.

Sorry to bring up an old post, but what was on your screen when you got into fastboot?
Got the same problem with my LG V50 I got from China when I tried to remove Magisk as well, now I'm stuck in the no command boot loop. Tried all of the button combination and I'm still stuck "No Command" screen, tried to manually check adb devices to see if it was detected every time it rebooted but still no luck.

and no reason other than im an idiot and hit uninstall after getting the phone back from a friend who "found" it with a newly broken screen and no battery or back, replaced screen and was getting " usb audio device not compatible with this device" when i would attach the second screen. I figured well , start from scratch cuz im an idiot and very green at rooting and flashing and this other dude raped my phone. That being said could educate me PLEASE on how to fastboot flash and would that be easier than Qfil or is that what your referring to....LOL. See? GREEEEEEn.
