Hey guys. I tried to unroot my nexus 4 from cyangongenmod using the nexus root tookit and it was all dandy until my phone just cut out. It won't turn on. I got into recovery mode, but i cant figure out what to do from there. How do i know if its still rooted? or if all i need to do is lock it again? Can anyone help? I really need help. Thanks

This is why I don't recommend tool kits. I don't what you did to the device. I would try to do a factory reset in the stock recovery. It will wipe your device. Locking the phone won't do anything so don't bother with that.

So how would i do that? Sorry, Im rather slow with all this stuff. What i have so far is the zip file from google developer page. Should I flash that from the sd card? Or is there a better way?

It's sounding like a hardware problem. I would try flashing the factory image with fastboot. Is your device recognized by your pc when you're booted into the bootloader? If not, go to device manager on your pc. Is there a device with a yellow exclamation mark. If so right click on it and go to where it lets you choose from a list on your computer. Choose android adb composite interface.

Hey Everyone,
So I was being impatient and wanted to change the Density of my LCD on my Nexus 7. I changed it from the stock DPI to 170 using LCD Density Modder on the Market. Ever since reboot I have not been able to get past the google screen when you first turn on device. I can get into bootloader as well. My bootloader is unlocked and device is rooted if that helps.
Is there any easy way to recover the device besides a adb, or fastboot method? If not, what are the adb, fastboot commands to flash the OTA image to device from my PC?
Thanks
Download the nexus root toolkit, it can turn everything stock.

I have the nexus root toolkit, but don't you need the device powered on to put in usb debugging mode, etc? All I can do is hit google splash screen and get into bootloader, recovery.
There's buttons that say revert to stock, I believe those work in recovery.

Whenever I try to flash stock + unroot I get error message, "Windows cannot find 'C:\\data\gnexwug_DLnX.exe'. Make sure you typed the name correctly, and then try again."
Im not trying to type in anything, all I am doing is trying to restore to stock.
did you make a nandroid backup?" i am goign through the same thing right now. I am goign to restore from backup.
To change the desinty, it must be manually done in build.prod i assume. LCD Density modder might not be compatible, yet.
edit: Crap, i cant boot to recovery for some reason :/
edit2: it seems the only way to boot into recovery now is from a ROM manager application. Ijust finished restoring using the Nexus Toolkit.
I finally figured how to get SDK going and restored via nexus root toolkit. Thanks guys!

Personally,
i booted into fastboot (all buttons if i remember correctly), then hit up the Tool Kit, go to advanced > temporary recovery, From there, i just restored my nandroid backup, or if you have any roms on there, just flash that.
You could do that, or once in fastboot and connected, you could just unlock, which will wipe everything.

Just using a file explorer (specifically, solid explorer but root explorer should also work), navigating to /system/build.prop, and changing the number ro.sf.lcd_density.
changing that particular number's easy, and the last app I tried somehow managed to make a second build.prop inside the same file. So yeah.
Don't forget to backup your build.prop (preferably externally as well, in case you need to flash it) before trying this. And/or make a nandroid.

Im not sure, i dont want to advise something that is wrong, but, no, it doesn't take extraordinarily long. How long has it been?
I would boot into fastboot again and try the other route (provided you have a rom on the device or hopefully, better yet, a nandroid)
If you're using the cwm recovery from the toolkit you must be plugged in to usb to access cwm from the bootloader menu. From there you can reflash whatever you want to fix it.

Yep, this is how it got it back and running last night.
I then used root explorer to edit build.prop and it worked like a charm.

I was trying to flash a rom and I guess I accidentally wiped EVERYTHING and now when I try to boot it says no OS is installed ): any helpp will be appreciated. I still have access to fastboot and recovery, adb also recognises it when connected

Hello, and apologies if this is posted somewhere in the forum already, but there are just so many threads to search through and i'm panicking!:crying:
Last night my Nexus 4 fell out of my jeans pocket about 2 ft onto my tiled bathroom floor. it has a diagonal crack from bottom right corner to 3/4 way up to the left side of the screen. I had a pattern lock applied and now because of the damage only the top 3 characters work which means in my case i cant unlock the screen. I am desperate to unlock it before repairing it because i have pictures of our newborn son; just 18 days old.
I have been told that whoever repairs it will hard reset the phone 'due to data protection'. I dont care about anything else on the phone, but i cant replace those photo's, so please, can anybody help me and let me know a way that i could retrieve these precious pictures?
some info that might be helpful? :-
It isn't rooted
Its the 16gb version
its running android 4.2.2
Its a UK handset (i'm based in the UK)
It does recognise the handset when plugged into a computer via USB, but i assume because the handset is 'locked' with the pattern, it won't let me download the pics.
Please help if you can. Thanks in advance.

Have you tried connecting your phone through USB onto another computer and accessing the phone's Internal SD card in "my computer"? If that didn't work... Then, do you have USB debugging enabled in your phone? If you do, then you can use ADB from the computer to pull the SD card contents (you don't need to have root access for that).
I can understand how you are feeling. I went through a similar situation when my Handycam hard disk got corrupted... but that's another story...

i have plugged it into my home laptop; it recognises the nexus 4, but i assume that because the screen/phone is locked, that for (security?) it wont let me download or indeed show any pictures.
Where do or would i find the ADB on my computer? i never turned on or off android debugging, so if it was switched on from the factory then it still will be.
Gutted!

Unfortunately, USB debugging is turned off by factory defaults, so ADB is out of the question.
I'd like to know what you mean when you say that the computer recognizes the phone...
Apart from that, you might wanna try one of these Freeware Android file explorers/browsers that don't require root access (google them). That way there's still a chance.
Don't give up.

flash TWRP in fastboot. Then boot to the bootloader and select recovery. You can use adb no problem from recovery. The exception is, I think you need to have the bootloader unlocked to flash a custom recovery (someone correct me if I'm wrong).

This should just factory reset your phone but not get rid of anything on your sd card
When your phone boots back up it will be as if you just took your phone out the box.. Hopefully you should be able to get the files on your pc as the screen lock would have been reset
Can anyone confirm?

[Q] Help stuck on "System Software not authrized by AT&T has been found on your phone
Well as the title says thats exactly what happened. It happened when I booted to recovery on Rashr recovery tools. Mistake on my part. I also know that there are similar threads, but I've already tried them out but they don't work for me. So I thought this would be the best way. The situation is well... its stuck on that error message. I tried to factory reset with ODIN but ODIN never detects my phone when I plug it in. I already tried taking the battery out and putting it back in. Then i tried Kies, but no luck there either since I can't find the serial number on the back of the phone sticker nor on the box of the phone. Does this mean my phone is dead?
Odin will work. You just need to get it to recognize your device. You have a usb driver issue. You need to install the court drivers. Kies should have done that but it can get in the way of Odin. Uninstall kies but keep the drivers and try Odin again.

With your device plugged into the pc, go to device manager. There's probably an exclamation mark on one of the usbs. That's the one having the issues. Right click on it and up date the driver. Go to where it say let me pick from a list on the computer. Pick the Samsung adb android interface, or something along those lines.

Towelroot wouldn't work. Says device isn't supported. Maybe it will get updated to work on lollipop. If I could obtain root I can flash custom recovery and start with a fresh install. Just have to find a way to do it with an app
