Hard Bricked - can't get into download mode

I have a very serious problem. I've managed to brick my device. I decided I wanted to install CM 10.2 on my E988 (Taiwan version) but it didn't work. I rooted, installed freegee and also had cwm. I put the files on my sd card and then formated data, cache and dalvik cache. When I tried to install from sd card it said can't partition non-vfat. So i decided then that I would push the files using adb to my devices internal storage. I managed to do this but when I did it said installation aborted. It didn't have anything else in the log. At the moment I can access cwm but I can't seem to do anything with it. I can also charge my device but the charging image is missing.
When I try to access download mode it comes up with the factory hard reset screen which does nothing.I am at the moment downloading the stock image kdz file but I don't think I'll be able to do anything with it.
When I boot up my phone it still says that freegee is installed.
I got the CM rom from here: http://forum.xda-developers.com/showthread.php?t=2439827
On that thread it says that you need to remove the first four lines of text in the updater-script file. However, in notepad, it depends on how big your window is to how much four lines of text is. Further into the thread, a user asked how much was actually meant to be removed and someone replied with all the way up to 'mount'.

Try, Remove battery and put again your device, hold Volume "-" and Home button and Power button, after display confirm put power button 3 time.

It's OK. It turns out that to get into download mode you don't have to press the power and volume buttons, you just have to press both the volume buttons and then plug in the USB

How to get there?
Power off phone
Hold power and volume down
when you feel vibration or see splash screen release power button but keep holding volume down.
Select menu items by volume down
Action your selection by power button
TIP, reboot phone is the last entry in the menu.
RECOVERY MODE
Is achieved by going into a bootloader mode.
this offers a menu with the following menu
Recovery
Fastboot
Normal
Image is fuzzy as its difficult to focus on it.
BEWARE font is tiny and difficult to read without magnify glass!
bootloader menu is about one nineth of the screen height
How to get there?
Power off phone
Hold the power and volume up
when you feel vibration release power button and continue to hold volume up
Select menu items by volume up
Action your selection by volume down
.....YES its not the same as Factory mode
more to follow later when I can take some decent screen shots
LONG PRESS POWER
You may be aware that while in either mode, long press the power button will for some options allow the phone go thru a reboot.
I just tested factory mode second last option, unfortunately it still treats the long press as
action current selection but then shutdowns and reboots
so don't try it on a factory reset unless thats what you want as you risk soft brick
good luck

Hello Guys,
I need help... I was mad because not been able to 1080p or 60fps playback on youtube. I decided to change the ro.build.version release from 4.4.4 to 5.. When I reboot the phone battery was on 1% (it was on 46% before) Then i used the backup of the build.prop and replaced it. Then i reboot the phone. The problem is that now i cannot turn it on. It stays loading with the Jiayu logo. Sorry for my bad english, i speak spanish.
Thank you

I don't understand what you mean with that.
If you can reach download mode(this screen) it's simple to recover it.

Sorry, I don't know how to help in this situation, maybe the nand is dead but I'm not sure.
Probably @Flippy498 can help you.

That's most probably a dead nand. If you want to keep the phone you need to send it to HTC for a repair. Your personal data is lost, though.

I can not post link to YT but I found there repair with changing nand + flashing with Ufi Box.

Galaxy A50 stuck on launch menu and cant access download mode.

Hey guys, today i made the horrible mistake to root my Galaxy A50... Long story short, it completly failed and now i think i bricked my device.
I have already downloaded the stock ROM and odin3 to install it but i am not able to do it because i can't access download mode.
To be more precise, i see the image linked below. When i try to force shut down my device, it does close for a second and then it vibrates and opens by itself at the same state. While launching i have tried all the volume up-down and power button combinations to open the download mode but everything fails. Note that i managed to open download mode in order to root my device but now it doesn't work.
Since i have no way of entering download mode in order to flash the stock rom using odin how can i fix my device?
The main image i see:

(Sorry for bad resolution, i had to take a picture with my laptop's cam..)
Thanks for your time, any help is kindly appreciated!

Okay so i managed to fix this. At first vol down and power would not turn off the device. It would start again by itself so i wasn't able to press volume up+down together. The solution was to let its battery die and then try that while connecting that to the computer and it worked just fine, i managed to get into the download mode and fix it. Thanks for the help!

Phone boots to screen I've never seen before, wont start up properly.

Hi,
I tried to reboot my Android phone (Lenovo P2) this morning but it brought up a screen that I'm not familiar with. It's the fastboot mode but without the picture of the Android lying down.
I can't boot into recovery (Power / Vol up / Vol down on this phone) and all other combinations of Volume Up / Volume Down / Power button lead to this same screen.
I haven't made any modifications to this phone for over a year now. OS is Lineage 18, and I use TWRP Recovery but I can't remember the version and I can't get into it anyway.
This is the screen I get when trying to boot. Sorry for the poor quality, I took the picture with my work laptop.
Can anyone help me get my phone back? Or tell me what this screen means?
Thank you, Simon.

You install another os and can't boot, try to reinstall the orginal os, you can contact developer, they will give you the link to zip to your phone

The phone has worked fine for about two years, which was when I installed Lineage OS. I did nothing to it other than turn it off last night. This morning I just get this screen.

Somehow, your phone doesn't boot to recovery nor android, I suggest flash the same custom recovery to phone back when you installed the custom rom/recovery and see whats happens..
If you can boot it with this, backup your files and change the rom and recovery, looks like its not reliable anymore. If you can not boot it (only recovery), try backing up your files in recovery and install updated rom and recovery.

Try normally rebooting. This looks like fastboot.

Join the club, flashing or booting into recovery from fastboot didn,t work for me either.
Was working fine till that day.
