My cousin managed to root his LG-C555, but then he deleted something in the core System, so now there's no Home Screen, no App short-cuts, no wallpaper, no access to settings, nothing but the pull-down bar at the top. He can turn on WiFi, BlueTooth, and USB Storage Mode, and that's it. Nothing else. Can't run any apps, can't access the system config, can't even make a phone call.
He tried a factory reset (using GREEN + RED + VOL_DWN) and all that did was restore what was left of the Android OS to it's previous, non-Rooted state.
So, my question is this: Is there a way to get the factory original ROM to come back -- or replace it somehow with a new image from USB Storage Mode, or is this phone history?

I have a Kobo Arc 7 HD that I was playing around with, and screwed it over.
My question is whether I can re-flash it if all I have access to is the adb sideload command. Is this even possible? Where do i get the image to flash onto it?
I just want to know if it will work even in theory, or i should stop trying to find a solution and toss it.
Currently it will boot to the home screen, but there is nothing there but the background, top bar and virtual keys. the top dropdown is completely empty, and the buttons respond to press, but do nothing. (the switch app button brings up a screen that says "no recent apps"). So thats a bust. When I plug it into my PC, it shows as a USB drive, and I see all the usual file structures.
I can get to the system recovery (vol down + power on), but factory reset / clear cache dosen't change anything.
I can do the update from adb sideload thing, but all of the images I have tried fail.
Thanks
I have the LG G4 (Verizon) which was upgraded to the stock Android 6.0 a few weeks ago. It is not rooted or modded. Last night I was sending some text messages when the battery died and the phone shut off. No problem, I'll just plug it in. However, when I did that the phone booted and said "updating app 1 of 1", which I thought was weird because it only does that when I upgrade Android versions.
So it boots into the home screen. I start playing around and here's what I notice:
--Wallpaper is different (stock)
--"Home" and "Show all apps" soft-buttons do not work. "Back" button works. (This is the biggest problem)
--Sound/haptic settings back to stock
--The top-bar swipe-down menu only contains current tasks, no buttons for location, airplane mode, hotspot, usb, etc
--Settings menu does not include option to connect to USB via different modes (Media, charge-only, etc). Connecting to a PC does not let me access to phone from the PC.
--My default text app was no longer the text app, although all my old texts are there
--Android version showed 6.0, and "last factory reset" was 3/6/16 at 10pm, which is weird because that is 36 hours in the future
I figured something got corrupted and I needed to do a factory reset. Upon trying to execute a factory reset from the settings menu, it displays the warnings and a list of my accounts that will be affected, but the "Reset Phone" button on the bottom is greyed out and will not let me click it. So I tried the other method....turned the phone off, held down power and vol down buttons, cycled power button when LG logo comes up. This causes it to hang there, then the Verizon logo comes up, then LG logo again, and will keep doing this back and forth as long as I cycle the power button on the LG logo. I never see a factory reset screen.
I backed up everything and need to nuke the phone or reinstall android somehow.....how do I do this without the ability to factory reset and without PC connectivity?? Or anything else I should try?? I don't want to take it to the Verizon store....

Verizon G4 Q&A, Help & Troubleshooting
Hello everyone!
Yesterday I powered off my Moto G3 and plugged it in to charge. After a few minutes I heard a short vibration, which normally means that the phone powered on by itself and is booting. I then checked the screen; I had to put in the PIN for my SIM card, but afterwards there was no pattern I had to draw in order to unlock the phone (I had one set up before!). After unlocking the screen I can see a blue screen with "Welcome" at the top, a choice of language and a yellow arrow ("next") button in the middle and "Emergency" call button at the bottom. And in the top right hand corner are the usual signal strength and battery icons.
When I press the yellow button, I'm asked to connect to a Wi-Fi network. I haven't proceeded beyond that point, as I don't want to mess up my phone even further. Basically it looks like my Moto G3 returned to factory settings and wants me to set it up for first use.
I then tried to reboot the phone a few times. I always get the standard Motorola "stitching" animation and get booted into the described screen. I also went into recovery mode, but almost every single option booted me into the blue screen and one time I got the "No command" screen. But maybe I did something wrong; I'm certainly no expert when it comes to using the bootloader.
Having described all of that, my questions are: is it possible for the phone to have reverted itself to factory settings? If yes - why and how? I have an SD card with a lot of photos, documents and application data that is very important to me. Is it still possible to retrieve the data that was saved on the device?
I would very much appreciate any help with this problem!
Thank you,
Meletel
You can copy the contents of the SDCARD while in TWRP.
1. Put MicroSD card and copy the contents of Internal Storage to microsd though TWRP File manager
2. Connect your phone to your computer by USB Cable while in TWRP and you can access your phone through MTP
we have two S7's, non-edge, and they have been almost bulletproof to now. I have a rooted S5 but have not modded either S7. My wife dropped hers, no breaks in the glass but it came up black after briefly displaying a partial image.
I can force reboot it, and it works. the backup 'key' lights up at times, the LED's work, and the phone receives calls [rings] but of course we can't see a thing.
Is there a fix? I've tried the reset via Vol - Power, that works to restart but no display. I've done Vol+ Power, can't see a thing. Tried Vol - Pwr Home, can't see anything so not sure what the result was. Plugged into PC but without being able to grant permission on the device, no dice.
How can I force a backup of everything? or... it may be backed up to her google account but how to reach, sans S7 display?:silly:
Hi, you can try to access the phone via samsung find my mobile website. You need internet connection at the s7 working and the logon data of your samsung account. In find my mobile there is a backup option.
Regards
Oliver
Fabulous! Going to try now
Oliver, unfortunately she never setup a samsung account period. hard lesson.
Surely the forensics community has a way to get to the stored data.... I guess/think the only things missing, that were not on SD card or SIM, would be a few pictures stored in default local memory, a few downloads, and things that will not be restorable easily like Calendar entries [and a whole lot of app cache stuff that is not high value]... am I wrong?
But then there is the security aspect; even if I cannot fetch usable data, I need to nuke it all... Is there no way to mount those volumes on a pc or other? A universal "nuke everything on the blind" approach?
thank you for your help
I have also black/blank screen but all audio works, hardware buttons work. I can tap the screen and it makes a sound. Voice assistant turns on for some reason and she verifies the touches I make to the screen. She also verifies I am pressing on screen buttons. I also know this because I can turn the phone off using the power button, then on screen buttons, even though it's blank. So the screen does work, just noting visually. I have tried the power + volume down to no avail. I believe the battery has totally died as was also recommended. If anyone has an idea of what to do next...please help.
, I believe, and I'm going to try today, that we can get in Via download mode. So we'll set up adb, set the "blind" s7 in download mode and see if I can browse the file system
My phone is Samsung Galaxy Note10 Lite (Android 12, One UI 4.1).
The device was working normally before I put it in my suitcase with many other phones without protection. After a while I took the Note10 Lite out and saw the wallpaper had changed to default like when I activated the phone the first time. A "Safe mode" text also appeared in the lower left corner of the screen.
I unlocked the device using password and it took me to the process looked exactly like a factory reset with Language/Region options and privacy settings to choose. I followed all of these steps.
After the "factory reset alike" was done, my 3rd apps were all gone, only system apps were kept. I opened Settings>Apps and no longer saw 3rd apps in apps list. I moved through the internal storage and noticed 15gb of data was loss. The strange thing is my media files (musics, videos,...) and documents are still intact, nothing has been deleted.
I tried to restart the system, also press the "turn off Safe mode" notification but it always show an error message when the phone boot up:
"Phone started in Safe mode. There's a problem that's preventing your phone from starting normally. You'll need to factory reset your phone to exit Safe mode. you can use Safe mode to back up your data to a computer or SD card before resetting your phone."
As far as I know, phone which turns into Safe mode isn't supposed to do a factory reset automatically. Does anyone know what problem am I facing with? I don't want to do a factory reset as the message said, because there are apps contain important data which will be lost if I reinstall them.
Booting into Safe Mode DOES NOT FACTORY RESET Android OS:
