[Q] Black screen after downgrade

I was running Cyanogen 6.1 on my HTC Dream fine, after that i decided for full downgrade. So i searched google for it and found the cyanogen wiki for doing it. I followed each step and after flashing DREAIMG.NBH to my phone, it restarted. And so it entered a boot loop. I took off the batery and then tried to enter recovery or the bootloader.When powering the phone normally, i see the T-Mobile logo, and after that, the screen turns black. Whenever i try Camera + Power, after the logo it goes to black screen. Home + Power points the same thing and so does back + power. Fastboot doesn't seem to work even though i have all drivers properly installed and the Android ADB Device shows under Device Manager.
I know i messed up because i didn't wipe before the downgrade. If there is any possibility to repair it? If so..what is to be done?
Thank you in advance!

[Q] LG G2 D802 Won't start after update latest Cyanogen

Hello,
I rooted my phone using "recovery_twrp" and installed supersu, booted to recovery mode and wiped the dalvik and cache options. The phone keeps hanging at that moment, rebooted again to recovery and than installed the latest Cyanogen ROM. This installed succesfully and when the device booted it keeps displaying the Cyanogen logo and nothing else......
I can't enter recovery mode anymore, i tried the ADB but it cannot detect the device anymore.
I tried removing the battery but it didn't work.
what can I do? my phone is useless now...
I also tried holding down power and volume down, release when the logo appears and then again, power button 3 times nothing works. It keeps showing the Cyanogen circle. The LG Mobile Support Tool doesn't work either. The good USB driver are installed.

download mode and flash stock is the only way I read so far.

lg g2 bootloop

Hello everyone,
i tried installing CM11 on my d802 with CWM. Flashed the zip and worked fine but im now hanging in a boot loop and only the CM splashscreen is showing. I tried to boot into recovery but it wont let me, only thing working is the download mode. I searched a couple of threads here but didnt really found anything that helps me.
Hope someone got an idea how to get my G2 working again, dont even care much if its stock or CM.

This happend to me with my LS980, heres what I did, i waited until my G2 was fully charged, i knew it was fully charged becuase in download mode you should see the letter B, the letter B indicates the battery, if your battery is at "B100" detach your phone from the charger, hold the power button for the phone to restart, and quickly press and hold the power button and the volume down button at thw same time,, repeat this step again quicly after the Boot Logo shows up, and you should boot into Recovery Mode and restore your backup.

howw to charge the phone when it on bootloop,whenever i plugged the cable its start bootloop

Stuck in logo after flashing stock. Can't boot into recovery. PC doesn't recognize.

So, I rooted and tried flashing the stock ROM (from Sammobile, same country, same exact model [SM-G950F], I already had the stock ROM and had never flashed anything else to the phone other than root, June security update, my phone had July's) to see if I could fix a problem that couldn't be fixed with any other method I had tried.
Everything in Odin seemed to go well, I got the PASS green box at the end. But then the phone couldn't go pass the Samsung logo when booting up. I left it quite a few minutes, before trying to boot into recovery mode and wiping data. Only to realize that I couldn't boot into recovery mode. In fact, I can't even turn the phone off. No combination of hardware keys works other than power button + bixby + vol down, to get into download mode. But that's of no use, because when I plug my phone into my PC (with the same cable and port I used before to root and flash the firmware into it) it is not recognized by Odin or the PC.
It just has the Samsung logo flashing slowly over and over because I can't turn the device off. By the time the battery dies out I'll most likely have the logo burnt into the display.
I also haven't been able to find any help online. Everyone's suggestion is “boot into recovery and wipe data”, but I can't do that.
Is my phone gone for good?
