[Q] Hard Bricking

What are the odds of hard-bricking the Nexus 7 while rooting and istalling a custom kernel? And if it bricks, is there a way to fix it?
I ask this because I want to root it, but I'm really worried.
Also, how can you fix a soft brick?

I think you should really care of these questions if you somehow corrupt both bootloader and recovery. I don't really know, but bootloader isn't a thing that is modified during rooting or changing kernel. Just carefully read the thread about rooting programs, follow the instructions and everything should be ok. The most potentially harmful thing that can be done is corrupting the recovery. It can be solved if you have a computer with adb and drivers installed. Just a sшmple command and recovery is reflashed. Unlocking the bootloader is a kind of thing that doesn't really change anything so you couldn't boot or something. It just clears the storage and changes something deep inside. Flashing ROMS/Kernels is a kind of coping files and if something goes wrong you can always reflash it from recovery or with adb or some app from the rooting kit. And also you can always flash everything stock. Just read and think of what you're doing. Good luck.

Can you help me, when I type fastboot oem unlock in the command prompt, it says <waiting for device>. Any idea?

You probably have not configured devide ids for adb.
But probably the use of "sudo" should solve your problem.

Are you on windows?
If yes, are you on bootloader mode?
If not:
1-Power off
2-Power On + Vol. Down
Then you execute "fastboot oem unlock"
If it doesn't work try to use any of the auto tools that you can find all over XDA forums

LittleConfucy, as you haven't told us what OS you're using, I'll assume it's Windows 7 or 8, doesn't really matter. Go here, download, install, launch, press the big button on top named "Full Driver Installation" and read what it tells you to do. It's written clear enough to understand. Just will give you some tips.
1. To install adb drivers, you should enable camera mode. It can be done in Settings->Storage. Just click on 3 dots and go to the USB connection settings. Select the option with PTP in its name and uncheck MTP if checked. After that your device should be recognized properly.
2. This App had a bug some time ago. It downloaded drivers and couldn't find them later. The workaround is to copy c:\Program Files (x86)\WugFresh Development\data\drivers\universal_drivers\UniversalAdbDriverSetup7.msi and rename the copy to UniversalAdbDriverSetup6.msi. It'll help.

Do you have any idea where can I see the drivers that were installed on the computer?

So I have to copy the file, paste it in the same directory, without deleting the previous file, and change its name?

Need help...
After I rooted, I opened BusyBox and it said:
"There was a problem opening a shell with root acces. This is either being caused by superuser/supersu or by a device that is inproperly rooted."
I downloaded root checker, and it says that it's not proprly rooted

adb issues. tough case.

ok, I am really in dead end here. I think I spent on it more than 4 days, trying to figure it out. No luck, hopefully someone here can help.
My One isn't recognized under adb fastboot. And what I mean: under device managers it shows that the device is installed fine ( no yellow exclamation marks ). But when I try to adb, no luck. No devices recognized.
wait.. before you refer me to gadzillions of links - I've been there, seen them. What I did so far:
1) Installed linux ( live cd and normal ). When in the OS, I can browse my sd card. Once I reboot into fastboot, adb devices returns empty list.
2) installed htc drivers, naked drivers, universaladb drivers, intel usb3 drivers ( tried on both usb2 and usb3 ports )
3) various laptops and pcs
no luck. I am running out of ideas. What am I missing ? pliz help, I am desperate to adb to update recovery.
PS. Tried that on windows 7, 8, 8.1 and linux

If your just trying to update your recovery you can use flashify from the playstore.

I don't recall seeing it mentioned in any of the recipes, cookbooks or how-to postings, but I found that in Linux, you should run your adb and fastboot instructions either logged in as root, or using sudo.

Make sure you don't have any phone software installed on the computer as well. HTC sync and Kies can cause problems with adb. Also make sure that adb debugging is turned on in developer settings. You probably already did that, but ya never know, I overlook the simple stuff all the time.

did you take 4.3 update
If you did I have same issue with adb but fastboot options work just fine as long as your s-off if you need any help let me know i went and reloaded hboot and a cwm and also wrote my cid to super and unlocked through htc dev then changed my cid back to verizons

thanks guys, yep, HTC sync manager was installed /uninstalled. Not sure what what's kies. Also I executed sudo on linux. Nothing freaken works. I am s-off unlocked via sonic. Drives me insanely mad. Seems like this phone just refuse to work with me.

I know this might seem like a dumb idea but have you tried a different cable? Are you using the one that came with the phone?

I don't know you so forgive me if what follows is too simplistic or unrelated to your issue. Just trying to help.
You mentioned your phone is not recognized "under adb fastboot." Do you mean under neither adb nor fastboot?
Are you trying to use adb from the bootloader? The reason I ask is you mentioned that after you "reboot to fastboot," adb devices comes up empty. I assume "reboot to fastboot" means reboot to bootloader, in which case adb commands will not work. Did you try fastboot devices instead?
You also mentioned wanting to get adb working to update recovery, but again this would require fastboot, not adb.
Hope this is the problem as it's an easy fix!

Once in a while I get humbling experience, that reminds me that simple solutions are right in the front of me Xenakis. You are correct, I was trying to get adb under fastboot, which didn't return anything. Fastboot devices did. From there it was all straight up road to what I needed. Sorry to bother you guys with this, I though it was more complicated that this. It just appears like my ignorance of basic adb commands got the best of me. Thank you for helping me out.
Merry Christmas

[Q] Problems with adb/fastboot after updating to Android 5.0.1

I recently updated to Android 5.0.1 on my M8 GPe and it seems to work just fine. Today I wanted to flash a custom recovery but I couldn't get any connection between the phone and the computer. When I enter fastboot I don't get "fastboot usb" as I usually do.
Do I need new drivers or something? I have both Windows 7 and OS X 10.10 so a solution for either is ok.

I don't think I get any connection with adb either? But I'll try that. What command should I use to flash the recovery image in adb?
Edit: adb devices shows an empty list.

Connect via USB
To see if you have a connection type
Adb devices
U should see a device
Then follow these directions
http://www.teamw.in/project/twrp2/225
You should copy and paste the dd cmd directly into terminal, if you typo that one u may brick ur device

Yes. And nothing has changed on the computer since before I updated to 5.0.1.

I'd say its the drivers. Try to reinstall
You can try adb over WiFi without the drivers, download an adb wireless app from the market, enable it, get the IP address of your phone in the app, then connect through adb
Adb connect <IP[emoji14]ORT HERE>
then try adb devices

Cant get fastboot to work!

I tried everything the internet could offer. Installed all the google and or OnePlus 5T drivers I found, many different ADB versions, enabled all the needed settings on the phone, yet when I type "fastboot devices" it comes up empty.
Followed many guides and videos, did all the steps. What could be the problem?

Digital signature of the driver or wrong drivers is the problem

Right, and (if you are a Windows user) after you put it into fastboot mode, you Need to overwrite the Drivers in the device Manager inside of Windows to the adb / fastboot Driver...
not just the "update Driver" Option.. you really Need to search und choose for the .inf file.
after that has been done, Windows should be able to find your device with the fastboot.exe
That should do the trick.
If you got any Problems Setting this up in Windows, and want some Support, I could help you remotely with TeamViewer application. (as far as our timezones allows us to do that)

Yes, it also did that for me after I plugged in my Device AFTER booting it into Fastboot.
BUT! since I'm on Windows 10 Education; 64 Bit, it somehow messed up the Drivers or something. Fact is, These automatically installed Drivers weren't working for fastboot (at least for me and probably for many others too).
the command "fastboot devices" wasn't able to detect my phone.
But if you download the needed adb / fastboot Drivers for that device and reconfigure the driver via device Manager on Windows
to choose the just downloaded adb /fastboot Drivers - it worked for me afterwards.

One thing i want to tell you is that,
You can install other device driver for that device too.
Just go to device manager and right click the unknown usb device and install driver from the list and choose android phone. or just download this driver and choose this using same process :- https://adbdriver.com/upload/samsung_android_usb_driver.exe
Dont worry this will work for every device.:good::good:

Best way to install up-to-date drivers:
Gett flashtool from the Sony website and extract the .exe with 7-Zip:
https://developer.sony.com/develop/open-devices/get-started/flash-tool
There is an executable file "Sony_Mobile_Software_Update_Drivers_x64_Setup.exe", install it

If you are trying to install the drivers in Windows 10, you need to go into safe mode and start the machine with 'driver signing disabled'
Then install the drivers.
You have to connect your phone in flashmode, go to the device manager, find the phone and manually add the right driver. Windows automatically assignes the wrong driver.
Edit: Sony driver is found here
