Hello guys!
I wanted to root my Nexus 4 today, and started to do all the steps. I downloaded all the drivers and setupped them.
Then I unlocked the phone by using this command on the correct folder in cmd "adb reboot bootloader".
It was succesfull. Then I did this step by writing this on cmd "fastboot oem unlock". I was succesfull too n there
was no problem. Then I setupped twrp recovery mode v2.6.0.0. But I didn't send the files of SuperSU to the phone. I tried to reboot my phone while it was connected to my pc with usb,the google icon appeared first, then the X icon of nexus appeared. After this, a screen showed up on my pc which says "the drivers are being setupped" but then it showed that it couldnt setup the drivers. Phone stucked here and cannot be started. There is only the X image of nexus but I cant start the phone. I can use recovery mode and bootloader only. So now can u please tell me what I did wrong and what should I do now to start my phone.
By the way I also tried to backup but it failed too.
Thanks, and waiting for your valuable answers.
Have you tried a factory reset from recovery?

Thanks for the answer. But if I factory reset, I will not be able to setup any roms cuz I cant connect to my phone from my pc with usb.
So if I factory reset, will I have to setup any roms to my phone ? Also I cant connect to my phone from my pc in recovery mode.
I did a factory reset. And my phone is working now. Thanks for everything. Çükünü yiyim abiii
I would recommend starting everything fresh. Follow this guide to revert to stock, then follow the root steps also in the same post.
Edit: Oops, posted too late. Glad you have it sorted out

After a successful day of unlokcing and rooting my new tablet, I decided to try and experiment with the dpi to try and get some phone based apps working using an app called "LCD Density Modder" I changed to Mdpi - 160, and the tablet turned off. It restarts to the Goolge logo, with an unlocked lock then dies again. What went wrong and how do I fix it? Help me out guys :crying:
Try holding down the power button for 10-20 seconds.
If that doesn't work, leave it plugged in for a couple hours and try again.

It turns on, and fastboot will show up, but Android will not boot. Or if it is booting, it's only a black screen. Is there any way to erase the pixel settings I've applied through recovery or the Nexus 7 toolkit? Or am I totally missing the point?
Edit: The screen does actually appear to be lit. Just black

do you have a custom rom recovery installed? go into your recovery and wipe data/factory reset. or if you flashed a custom rom, go into the recovery wipe data/factory reset and reflash your rom.
I've tried this, to no avail. After the Google logo, a portion of the screen flashes pink and the tablet goes dark again
You can use wugs toolkit to reinstall a factory image, or you can sideload one using fastboot command, wugs method is easier. The file you edited is the build.prop if you still have adb access you could use adb shell to edit the file and change the settings back. Sadly I don't have a clue as to the default settings for dpi in the n7 build.prop.
Cheers Danny
After attempting to factory reset, and trying all these methods I realized that USB debugging is now disabled :crying:
Have you tried booting into recovery (power and volume down) whilst the tablet is connected to the PC via USB? I found that helps you get into recovery sometimes from bootloops etc.
Cheers Danny
Yes, I can get into recovery and fastboot but any attempt at booting Android results in a black screen
Kk come down.. Boot into Fastboot download wugfresh toolkit, and click the flash back to stock and unroot option and check the box that says device will not boot.. Problem solved

I tried to, but the drivers wont install because it won't boot
Forgive me, I can do all this but I'm a little slow :silly:
Shafe when you rooted your tablet how did you go about it?
Did you use a toolkit? If so which one?
What type of computer did you use, windows, Mac or Linux?
If it was windows which windows was it, XP, vista, 7, 8?
There are known problems in getting drivers to work with certain windows etc. But if you used a toolkit to root then you must have had working drivers at some point during the process.
Any more info you can provide will help get to the bottom of this
Cheers Danny
I used the not so creatively named Nexus 7 ToolKit v 4.0.0 on windows 7. I've had the drivers and just reinstalled them from the toolkit, so they are now on there again. The problem is that I factory reset and since Android won't boot, I have no way of enabling USB debugging
Grab wugs from here
http://forum.xda-developers.com/showthread.php?t=1766475
[Toolkit] Wug's Nexus Root Toolkit v1.6.1 [Updated 11/30/12]
And follow Francis instructions posted above, should sort your problem. You won't need more drivers as you already have them installed.
Cheers Danny
I tried this a couple times, but after trying to flash stock + unroot it says my ADB device was not found because USB debugging isn't on
Found a guide that will allow you to restore stock through fastboot
http://forums.androidcentral.com/ne...1477-guide-nexus-7-factory-image-restore.html
I am not experienced enough with fastboot to really be of more help. Hope this does the trick.
Cheers Danny
Yep, I found this a few minutes ago and am giving it a shot. I'm inexperienced also, but I guess I'll have to learn! Thanks brother
Forget all toolkits and use fastboot, you'll gain twice that way; working N7 and also you'll have gained some knowledge.
It's a lot easier than it seems.

I used the toolkit for mac and it unlocked me, but when it came to the next steps it said device not found and then told me to highlight recovery and press start, when I do I get the android with the red ! symbol.
Can someone help me?
That symbol is a security feature within the stock recovery, volume up and power to access the stock recovery.

For me also Stock recovery never worked. Just try to flash CWM or TWRP.
Btw, What toolkit did you use and how did you install the drivers. Please answer these, so that someone can help you better.(Or is it just the 'mac toolkit' ?)
My suggestion: PLZ DO NOT USE TOOLKIT. If you are stuck at some point while using the toolkit, then you'll not know what went wrong and how you can correct it. Do it manually. It is the most hassle-free method. Trust me.
I think that ADB will not work in stock recovery(may be you can boot normally into your phone and then try adb). The thing which you are looking for is 'fastboot'.
1) Restart ur phone (Power Button + Volume Down, i guess) and land in the bootloader and connect your phone to PC.
2) In CMD prompt(or Terminal), type 'fastboot devices'. If your device gets listed here, then fastboot is working and drivers are properly installed. If not, then drivers are not properly installed in your PC. You need both ADB and FASTBOOT drivers. Install them properly.
PS: For MAC, i think the command is slightly different. Something like './fastboot devices' . Please look for the same in this forum or just google it and find out.
3) Follow this guide for flashing CWM and Rooting.

4) For properly installing the Drivers, read " A. Install the drivers " in the below thread (actually you can read the entire thread )

I used the nexus 4 Mac rootkit I found in here.
It unlocked my phone fine. But when it came to installing a recovery and root it didn't.
Neither my adb or fastboot are working now before I unlocked and I messed around and they worked now nada ...
I went to YouTube saw my problem tried pressing volume up and power like in the video and it just gives me a black screen and either turns the phone off or reboots it normally...not sure if in supposed to hold power and let go of volume or vice versa.
I placed all the files on the storage I just need to access stock recovery which I strangely cannot now...
Tried framearoot and got nowhere.
Very frustrating

Just as I mentioned, i also had the same problem with stock recovery. So I simply flashed a Custom one(CWM, in my case)
Get the ADB and FASTBOOT working and that'll solve your recovery problem. Try fiddling with your drivers again. Not sure how to do that in MAC. If FASTBOOT is working, the you can boot into a Custom Recovery(you need not even flash it) and perform whatever you need to.
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Again, look at the efrant's guide i referred above; i took this from there only.Remember to replace 'customrecovery.img', with the actual downloaded custom recovery image name.
Or you can try posting your problem with the toolkit, in mac toolkit's thread.
I have been youtubing everything and finally got to
Reboot system
apply update from adb
wipe data/factory reset
wipe cache partition.
I now can get adb working so I tried ./adb sideload cwm from my desktop and it is giving me signature verification failed. installation aborted.
What can I do to resolve this?
I searched xda and no one can solve this issue from the threads I've read.
I fixed it! Whooohoooo! Installed cwm and root ....now to install pa rom.
Thanks for the help!

Save save technology myths, to with a very big problem here, once the XDA released the preview of Android L for the Nexus 4 I installed on my machine, everything went well for quite a while, until one day the phone opened an APP "encrypt" the machine, and restarted, the process lasted about 40 minutes, and then it ended, I called the appliance and to my surprise was the following message: "type passowrd to decrypt storage", and a place for me to enter the password.
Was the beginning of my despair, I had not entered any password or PIN, or those design patterns android... The device simply was encrypted with a password which I did not know what it was.
To tackle started with the basics: with the recovery already installed I did the procedures to restore factory defaults, and connect to my surprise, the message was still there, then went back to recovery and wipe gave in practically all I knew I could give, I called, and again the message was there. Not knowing what to do and already pissed off, I left the cell phone away, and another time when I connect it to my surprise it was an infinite loop.
That's when the idea to install android again, and when I went to "install zip from sdcard" received the following message: "and can not mount / sdcard".
Today I have done the installation procedures via fastboot and ADB or where they do not recognize the device for his fact not be connected with USB debugging.
Anyway, do not know what else to do, I've used all my knowledge and nothing to solve this problem.
Please, help-me
You're going to want to flash the factory image in fastboot. Google 15 second adb install. That had usb drivers. Once you install it boot your phone into the bootloader and connect it to the pc. Type
fastboot devices (in a command window).
If your device is recognized proceed to flashing the factory image.

Hello everyone,
So ive been lurking on these forums for some time now looking for a solution for the mess I just created, but its been so long now that I want to ask if anyone can help me out now.
The situation is I bought a LG G2 AT&T, and then proceeded to root, recovery and everything was flawless, but I tried to install another ROM and this is went everything went to hell (Im from Mexico). It went all black and with the "Fastboot mode activated" and stuff so I went an put it on download mode and tried by all possible ways, the LG Flash Tool and the LG Flash tool 2014, both ways do not seem to bring back my phone to life.
Whenever I try to install it like this, I get this error with the D800AT FW. I get this error.
And whenever I try to install with D802 FW. I get this one as well.
When I try with the Lg Flash Tool 2014 method. I cant get it to 100%, I always get stuck on 99% And then it crashes.
I am really running out of options here, the phone is recognized by the PC, but I cant get to install a normal working stock ROM.
Any pointers, or help, would be greatly appreciated.
Thank you.
EDIT:
Apparently, I cant post images just yet to show you the exact error. But for the first 2 errors, I get something like this.
"DOWNLOAD FAIL! Check phone or DLL" both for D800 and D802
If you have twrp as your recovery you can adb sideload a rom onto your device from your computer. Google how to sideload adb with trwp installed and follow the instructions. If your phone is recognized it should be fine.

First of all, thank you for your response.
Now, it is still recognized, but I tried to flash it with some DLL a guy provided on this one thread (http://forum.xda-developers.com/showthread.php?t=2663369) and it didnt complete, it just froze on 94% and now I cant get to Download mode.
I saw about the adb sideload, but I cant seem to access to Recovery now. Tried to, but all I get is some kind of bootloop just showing the LG and android with the open belly and then back to LG.

So the three finger method only gets you the android with the belly up? Is your phone still recognized? I'm on Verizon but i think with other phones it's the same process. If you have no recovery you need to tot back to stock. I've only done it once but it did work. This is what i used to fix my problem when adb didn't work. Lots to read but it does work and people will answer if you have a problem http://forum.xda-developers.com/showthread.php?t=2797190.. Good luck man.

If I try to enter Recovery I enter the stock one and just asks for a Factory Reset... I can not enter download mode now, I get fastboot mode only when I try download mode. Phone is recognized by computer when I connect it, but when I try to enter Download, it does show the device on device manager, but it sounds weird and I cant do anything.
Im really starting to lose it.

I successfully rooted my LG G2 D800 using One Click Root http://webtrickz.com/how-to-root-lg-g2-running-lollipop-with-lg-one-click-root/ and it's running Lollipop 5.0.2. However, I want to install Cyanogenmod 12. Trouble is, I can't get into recovery mode, only fastboot. No matter what method I use: Power/Vol, I get fastboot. Quick Boot or TWRP; fastboot. This is not my first time flashing, but I'm stumped this time.
The black screen shows
(1040) Fastboot mode started
When the phone is plugged into USB:
(1040) Fastboot mode started
(52440) -reset-
(52450) -portcharge- (or maybe portchange, the letters are tiny)
(52560) fastboot processing command
Nothing happens after that. I can restart my phone, no problem, and have gone past fastboot to "Factory data reset" and "Erase all user data and store default setting?", clicked yes, but wind up back on the black screen and fastboot..
No doubt, it's something really simple that I missed. I'd really appreciate some help.
Do lots of drives pop up when you connect your phone to the pc?

Do you have adb-fastboot drivers installed?
Also,after installing them,connect your phone and let the PC link those drivers to your phone.
