[Q] [HELP] Bricked G2 D801

Hello,
I tried to install custom recovery with AutoRec
however I didn't use IOroot like they suggested, I had rooted with TowelRoot
After which I was in fastboot mode without download mode.
I followed a guide and rewritten recovery and laf as well as all other img I could find at http://downloads.codefi.re/autoprime/LG/LG_G2/D801BK/Stock_Firmware/10c_partitions
PHP:
fastboot erase recovery [return]
fastboot erase laf [return]
fastboot flash laf laf.img [return]
fastboot reboot [return]
I got to download mode, but my phone is not detecting the download mode (no usb connection, no usb connection sound)
If I plug in the phone regularly and let It boot - it is stuck at LG logo, and if I plug it in - I hear USB connection sound and it detects, however I can't use the flash tool (2015 or 2014) to flash it.
I changed the port to 41 like in the LG tool flash tutorial (http://forum.xda-developers.com/showthread.php?t=2432476)
Today I tried to go Ubuntu Linux path - and plugged it in in both download and regular mode (like in this guide http://forum.xda-developers.com/showthread.php?t=2582142)
and I didn't see it plugged in when I typed
PHP:
ls /dev/sd*
I am under windows 8.1
I also tried windows xp sp3 virtual machine
Anything else that you can suggest?
Thanks
Andrew

I can go to download mode, but computer doesnt recognize that it's connected (doesnt appear in device manager)
I can only do factory reset. (Vol Down + Power) thats the right way, correct?
Don't see any other options.
When I try to get out of the factory restore screen by pressing any vol up or down - it hangs

Restore these partitions in fastboot,
1- sbl1.img
2- aboot.img
3- rpm.img
4- tz.img
After this, your phone must be detected by computer,

Factory reset will make when u will press 2 times power button, no vol, correct it. If you can go fastboot, u can rewrite your partitions.
Factory is vol - + power and while pressing vol - repress power button

fastboot turn on only when images wrote is not valid. So dont try this. Try go factory reset, or bootloader

Hi ,
The phone does not react at all after installing recovery .img 3.1
The phone is starting to shut down
not work fastboot mode
not work normal open
not work recovery mode.
sorry bad english
Try booting into FTM mode (Volume Down and Power) and do an "adb reboot edl" to get into EDL mode. Once there you can flash a stock ROM via MiFlash.

Fastboot/download mode?

Does this phone have? Is there a way to boot into such mode so I can flash something via fastboot?
Power and volume down keys just lead to some test mode. Holding the volume down while connecting USB does nothing as well.
I'm just having the same prob with --U51
Thanks
Not meaning to necrorez a thread as the entire forum section is inactive...
On Y625-U21 the best way to enter fastboot mode is via adb:
- activate usb debug
- use "adb reboot bootloader"
you are now in fastboot mode. Notice that on the phone you won't see a special screen: just the huawei logo like it's stuck, but you can use fastboot to do what you want (unlock the bootloader since it won't require codes, run TWRP, flash TWRP etc etc...)

How to enter into recovery if no rom is installed and volume keys are not working.

I do have TWRP installed.But i want a way to get into it(Using adb maybe) since volume keys are not working and no rom installed. Getting into bootloader is not a option since there also i need volume keys to navigate. and when i try to boot up asus symbol flashes for a second and then usb symbol. plzz help
How to recover Stock ASUS ROM:
- Reboot into FASTBOOT MODE
- via adb type command fastboot flash recovery recovery.img
Try This and download recovery.img from https://forum.xda-developers.com/zenfone-5/development/recovery-twrp-3-1-1-0-asus-zenfone-5-t3657781

Unable to install twrp in redmi 2

So, I followed anandmore's thread https://forum.xda-developers.com/redmi-2/how-to/ultimate-guide-redmi-2-users-rooting-to-t3294212:
I did following commands in fastboot mode -
fastboot devices
fastboot flash recovery recovery.img
fastboot reboot
But after rebooting, it gets stuck on MI logo. What should I do?
Can you get into recovery? I don't remeber what button combination it is on stock rom, but on custom is it VOL UP + VOL DOWN + POWER, when phone light up, release power button and keep holding the volume buttons
The commands you need are
fastboot devices (for recognise the device)
fastboot flash recovery file.img (you can change the name file if you want, to be easy)
fastboot boot file.img (this command is necessary for the first boot into the new recovery flashed)
You need open the CMD ADB/Fastboot in the same file folder with the recovery.img, if not, not works
Hi, I had the same as you. You need to press the buttons as the other user said (volume up + down + power), when the phone is off. And hold them until you see twrp.
(FYI, the phone will boot with miui logo, then it takes maybe 15-30seconds to show twrp, you need to hold all the time I think, until twrp shows).
Thank you B.Paiter !!
"fastboot boot file.img (this command is necessary for the first boot into the new recovery flashed)" did it for me !
