thanks

You can't and you won't need it. Read this guide, download the latest factory image from here https://developers.google.com/android/nexus/images (be 100% sure to download the one that is for your device).
Follow the guide from "Extract the Factory Image" and in the "Flashing the Factory Image" section you can skip to 4).
Good luck.

Formatted Phone, ADB not found

Hi, I accidentally formatted my phone yesterday night. Trying to flash the factory image from command prompt using this guide http://forum.xda-developers.com/showthread.php?t=2010312 but I am stuck on Google logo and cant enable the USB debugging mode under settings. I think i did install the driver using Root Toolkit as it shows under device manager but toolkit says adb device not found (see attached).
Please advise how can I bring back my phone to normal.

Boot device into boot loader and in the toolkit tick the current status as "soft-bricked/bootloop" and do a "back to stock"
*hint* You don't need ADB; you need fastboot.
Have, same issue, but in bootloader mode, windows not seen device.
Only what I have chance to fix it, write some from usb-otg thru twrp?
In download mode too several computers with different cables not see device. Only one pc with windows xp reconize unkown device with pid vid 0000

Nexus 7 Stuck in Boot Loop After Font change

So to make a long story short, I've been stuck on android 4.2.2 for a while now because I changed the Roboto fonts (Roboto Bold, Roboto Italic, and Roboto) After discovering this I went and re-rooted my tablet to put the fonts back on so I could OTA update. I couldn't find the fonts on any font applications that matched the SHA1 checksum, so I plugged my device into the computer to put the files on manually I downloaded earlier. This is where some problems arise. My computer has having some problems with the drivers for some reason, so the only way to move the files on was if I turned USB debugging off. So thats off, and my computer won't register that the device is plugged in. Well now we get to the part of the story where I was using ROM toolbox lite and tried installing all three of the new fonts all at once. Bad idea, I now know. So my device is stuck in a bootloop, and when I try to go into recovery mode it gives me the error: No command set. I have no idea what to do guys. Any help is very much appreciated. It is kind of upsetting how a change in fonts can brick your device.
1. Download and install Nexus Root Toolkit v1.8.0: Nexus Root Toolkit v1.8.0 | WugFresh
2.. Connect to PC and Boot in Fastboot Mode: VOL DOWN + POWER ON
3. In the toolkit, under "Back to stock" tick "Soft-Bricked/Bootloop"
4. Click "Flash Stock + Unroot"
5. When done you will (should) have a working Nexus again.

Hello, Thank you for the helpful tip on how to fix this. I tried what you said but a problem appeared making the device fail to apply the factory image. What I am assuming is it was because the root that I used did not make me unlock the bootloader. so i'm doing that now. It should let me flash a factory image after that, right?
UPDATE: I tried unlocking the bootloader, but it didn't work. my device is not being recognized via ADB because I think the drivers are not properly installed, or it could be because USB debugging is not on. So I cannot get to the point where I can unlock my device.

I have the same kind of problem. Did you manage to unlock it?

[Q] SO there is no way to enable USB Debugging on a bricked N7?

Rooted my N73G with Clockwork back in 12/12 when I bought it, worked fine for a year and change. Last week it wouldnt boot past the glowy X. Tried resetting cache, Dalvik cache, and factory reset options in Recovery Mode. Nothing
Downloaded the SDK as a couple different tutorials instructed. Tried Skipsoft's toolkit. Why does every bloody recovery tutorial tell you "enable USB Debugging in the Settings menu" when you cant bloody well boot to a working OS???????
Needless to say, everything I try deadends at unable to do whatever because USB Debugging isnt enabled. Now it wont even boot into Recovery Mode, stopping at the bootloader.
Wat do?

If usb debugging was enabled, one might save the important files from the device before flashing it.
Since you boot into the bootloader, you can flash a factory image. I recommend this guide but all of your data will be gone.

From the linked guide (the one I've been using) "Enable usb debugging on your device (found under Settings > Developer Options)
NOTE: Since Android 4.2 the Developer Options are hidden by default."
How can I enable USB Debugging on a tablet that is bricked? Further, the SDK program doesnt see my tablet connected. I hear a little connection tone in windows when I plug it in, but running adb.exe from the command line and using an "adb devices" command shoes a "List of connected devices" that is empty.
Only the Skipsoft toolkit seems to want to even see my tablet, no matter what USB port I try,
There is no need for adb (it is only used to boot into bootloader). What you will need is the fastboot commands in the "Flashing the Factory Image" part, but be carefull to flash the proper image and to the proper partions.

[Q] Kind of Bricked My Device (Nexus 7 3G)

So what happened was that I tried to install the update of paranoid android's latest version. Since TWRP cannot install it, I used CWM. All my back-ups are in TWRP so I had no chance to restore. Now, my device is stuck in recovery mode. I could enter the fast boot mode. Now I don't know what to do since all guides in restoration say that I have to enable USB debugging, something impossible in a device which cannot enter the interface.
Please help. Thanks
You only need fastboot access so you don't need usb debugging, but you will need the Android SDK.
1) Read this guide.
2) Download the latest factory image from here.
3) Follow the guide from the "Flashing the Factory Image" section's 4th point.
Good luck.

FAQ
1. Having problems with device connection? like waiting for device.
Sol. Make sure you have enabled USB Debugging (Not applicable for BL Unlocking and TWRP Flashing)
Uninstall all drivers previously installed on computer(every driver of any device)
Reboot your computer. And then install all drivers given in the driver folder.
If the problem persists, try different computer and different usb cable.
2. Facing permission denied in fastboot mode or while running script files.
Sol. Try disabling your lock screen security to none.

Would it not be easier to get the stock raw image and just flash it with the asus flash tool?

Thanks for suggestion. But the reasons​ are
First thing is stock raw image of latest version is very difficult to find.
Second thing sometime asus flash tool stops responding. So you have to wait again for 30 minutes. Also it doesn't show progress sometimes.

No offense meant. But the entire collection of raw files are here: https://forum.xda-developers.com/showthread.php?t=3448966
As long as you have the correct drivers (which you need for your process too) the AFT will get the job done in one easy step.

I have the Asus Zenfone 2 ZE551ML with sound issues, (it's only when the phone rings that the speaker works) and I put it into recovery mode to wipe cache/data, but it got stuck while doing that and I forced it off. But now, it's stuck at the Asus Boot logo with the rotating icon underneath.
Please help!!!!
Hello, my 551ml has stock LP, it's rooted with bootloader unlocked and Xposed installed. If I want to install the latest MM with through the raw flashing tool, should I install the MM bootloader first or it is included into the raw file? Thank

"Can't open file 'SERIALNUMBER_frp_request_server_log.txt' (error 5:denied access)" i can only press OK
and now the button under "state" is red and under description, it's " check the detected serial number failure (not found the device of "SERIALNUMBER") "
you understand the i've replace the real serial number by SERIALNUMBER in those lines.
Anyone ever had this problem?
