Semibricked LG G4 after removing bloat apks

Hi all,

I semi-bricked my device (815) while cleaning from bloatware.
The last stuff I cleaned were some drm-stuff from LG which might caused my booting being stuck at Boot with Security Error, Authentication failed.
I am rooted and on Genisys 1.0 Rom and I would reflash it with command Flash but I removed the System.img from my internal sd Card.
I managed to copy it to the external sd Card but can't get the proper command to Flash it from there. Maybe the external sd Card is not even mounted in Download Mode?
Unfortunately I have no custom recovery installed so flashing a zip over this method is not possible.
Hard Reset of the phone is not working, there Comes a small error message with "secure boot not working".
Any ideas? :(

Best regards,
Matze

Phone Semi-bricked

Hello all!
So recently I was playing around with my G4, and decided to see if i could boot into fastboot mode. Turned out I could: theandroidsoul.com/lg-g3-fastboot-mode-61660/, but it would remove download mode in the process. It was totally useless. I couldn't run any commands and so I decided to put download mode back. I rebooted my phone, a notification caught my eye, and I completely forgot to put it back.
Fast forward a couple days, and my phone starts to run at 2 miles per hour. So, I factory reset, losing root and recovery in the process. That still didn't fix it, and now the camera, all speakers, and microphone don't work. Now, I can't replace download mode without root, so I cant run the LG Flash Tool. I'm starting to lose my mind over this. Please help!

Semi-Bricked One X while trying to install Revolution HD ROM

Hi all,

Not been here for a while so hello to all again!

My HTC One X is in for repair so I'm using my spare old phone - HTC One X.

Today I tried to install the Revolution HD ROM - yeah - I should have waited until my One X was back but such is life!

Anyway - I've not even managed to successfully install it yet and the One X sill have the Orange installed ROM 4.1.1.

I'm not sure what's happened but now the cellular and wifi / bluetooth won't start...I've tried a factory reset but it's still the same.
Apart from that from what I can see the rest of the One X works fine.

All I've done to get the Revolution HD ROM installed was dump it to the internal storage and run the win boot.img and enter recovery mode to flash it....when I did the last part I got a red triangle in recovery which I assume means it can't find boot files.

Can anybody help me resurrect it please? Thank-you!!

Semi-Bricked N7. Boots normally, but no fastboot or recovery

Hi All,

Really strange situation with my N7. I'm unable to boot into Fastboot or Recovery and when I do, it "bricks" my N7.

Or at least it does, until the battery drains after a couple of days. At which point, charging it backup allows me to reboot normally.

So the big question is, can I repair/overwrite the corrupted bootloader partition when it's running normally?

My device is unlocked, rooted, has SuperSU and BusyBox installed. In addition, I can run ADB commands, just no joy with the "adb reboot recovery" or "adb reboot-bootloader". I also have a TWRP created Nandroid backup, but without recovery working it's not really of much use at the moment.

Was thinking that maybe I could try sideloading? Or maybe there's a BusyBox command I could use to overwrite the bootloader partition? Or maybe there is something I could do while it's in APX mode using nvflash (if I can extract security blob from Nandroid backup)?

Any help would be appreciated. Seems a waste to install a new mainboard, as it still boots normally.

Many thanks!
