Hard Brick fix needed for zv8 update (used TWRP terminal command) - Sprint LG G3

was on zv6 and was updating to zv8 using the twrp terminal command method. i had the system.img, boot.img, modem.img, rpm.img, and tz.img. I flashed them in that order using the following commands:
note* I did enter the system.img command multiple times because no result was showing (i forgot it was a 2gb file)
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
dd if=/sdcard/rpm.img of=/dev/block/platform/msm_sdcc.1/by-name/rpm
dd if=/sdcard/tz.img of=/dev/block/platform/msm_sdcc.1/by-name/tz
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
boot, modem, rpm, and tz showed the "files removed and files installed" log and were complete. the system.img never did (waited 20 minutes). after the last entry of the dd...system.img..., it said no available space while flashing tz.img. I rebooted into system. TWRP asked if i wanted to root and I swiped for yes root.
the phone shut off and will not power on, no led when charging, no download mode, no recovery mode... NOTHING. can LGflashtool fiz this? I have a nandroid backup so I'm not worried about losing data and will flash back to zv4 if necessray.
Thanks

Well in order to use the flashtool you have to be in download mode. Since you cannot boot that really wont help you. At this point your best option is to contact sprint and request a replacement device. The only reason I say that is because it is a hard brick and the device will not power on. Now if it was a soft brick it would be a whole nother story.

I did the same as you, ended up softbricking my phone. Had to flash with the LGFlash tool and start from Z4

Why were you flashing all those IMG files?;makes no sense to me . What were you trying to do?

[Q] fix_recovery_loop.zip

Does some one tested the fix_recovery_loop?
If so tell me if it works plz.
You will find a shell script in the zip file, if it does
dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1
dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1
as per option 1a, forum.xda-developers.com/showthread.php?t=1514088
I would trust it (for tf201)
In answer to your question yes this does work. I've used it multiple times to get out of boot loops when I've used clockwork.

[Q] Switch from TWRP to CWM

I rooted my TF201 using Urkel's Fresh Start method, which included TWRP as a part of the process. I felt more comfortable with CWM, so I tried flashing it, but now I can't enter any sort of recovery mode at all. It just hangs at the Asus logo where it tells me my device is unlocked.
I've tried flashing in fastboot mode:
Code:
fastboot flash recovery recovery-clockwork-5.8.3.4-tf201.img
fastboot flash -i 0x0b05 recovery recovery-clockwork-5.8.3.4-tf201.img
(What does the -i 0x0b05 flag do?)
While in Android, to force the recovery image to flash:
Code:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb shell dd if=/storage/emulated/0/downloads/CWM/recoveryblob of=/dev/block/mmcblk0p4
(Which partition should that command really be going to?)
Tried with different images of clockworkmod, official and unofficial to no avail.
How do I get CWM to work again? My TF201 is otherwise working perfectly, but obviously it'd be nice to have a working recovery.

FIX: Bootloop with OTA and TWRP (bumped)

If you accidentally take the OTA and have the bumped twrp installed you'll find yourself in a bootloop.... to fix it do this;
If you have ADB access (once booted into twrp), plug in your phone to your computer and do this:
Code:
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
If you DONT have ADB access for whatever reason or you do not have access to a computer or something you can use TWRP's "terminal command" option to do this:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type the above out with the onscreen keepboard so be very very careful to get all the spaces and /'s.... One wrong letter and you could blow up your phone.
After you can reboot and it should boot as normal.

Fastboot into download

I was using a guide, https://forum.xda-developers.com/android/help/guide-how-to-lg-d-631-att-fastboot-t3130955, in hopes to use a custom recovery to restore my phone, it didn't take. Which lead to this problem.
During the process, I used ADB and inputed this command:
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
(I also ran this command to zero out the actual block partition)
dd if=/dev/zero of=/dev/block/mmcblk0p15
So I found this guide, after finding out that a tot file is the only way to restore.
https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
I did well until the final part of step, which requires the phone to be in download mode. I realize the problem is that the phone is in fast boot instead of download/driver mode, and I have no idea how to switch it back.
Also, The fastboot reboot command does nothing, and it flatout rejects the reboot into bootloader command.
