Figured this would cut down on threads and questions. I have made a video showing how to manually update to 4.1.2 (WILL ALSO WORK FOR 4.2, just use the correct file that I link to) on your Nexus 7.
http://www.youtube.com/watch?v=PwlXQoAzrBE
Hope this helps.
Thank you =) will try
-Google
I hope people actually watch and learn from this tutorial instead of waiting around for some point and click tool powered by unicorn blood and hamsters. It's an excellent tutorial and gets you in touch with your device by using the exact tools Google provided you to use for this exact thing.. Use them, they are invaluable.
This means we can't use the old method of putting update.zip file in the root folder and let the system upgrades by itself.
Terrific video but for one problem: My N7 doesn't seem to want to go into Recovery.
Using adb reboot recovery gets me into the red triangle screen, but pressing Power+VolUp just gets the Google logo and pressing all three buttons just restarts it. Something is screwy and I've wasted about three hours on messing with it. I never get the screen shown at 3:41.
If I cold start it by pressing Power+VolUp+VolDn, it brings up a screen with an Android on its back with the body open and a big green Start pointing to the Power button and arrows next to the volume buttons. In the lower left in white computer type is:
FASTBOOT MODE
PRODUCT NAME - grouper
VARIANT - not defined yet
HW VERSION - ER3
BOOTLOADER VERSION - 3.34
BASEBAND VERSION - N/A
SERIAL NUMBER - xxxxxxxxxxx
SIGNING - not defined yet
LOCK STATE - LOCKED
Pressing up or down twice brings up Recovery and pressing Power switches to a Google logo and that's the end of the show.
I followed your "How to install the Android SDK, ADB and Fastboot on your PC" video without a hitch (thank you for that one, too) and I have USB debugging turned on (as proven by adb reboot recovery working), so what the heck is going wrong with getting it past the red triangle screen?
EDIT: I'm bone stock, no root.

I have the same exact same problem, except my bootloader is unlocked. Tried everything I could think of, and it still doesn't go into android recovery.
Insert your USB cable and make sure it's plugged into a charger or PC.. Recovery won't appear unless you are plugged in. It's an odd bug fixed when you update
I've been plugged in to both a charger and the PC. Come on, if I've fired off adb recovery reboot, doesn't that automatically suggest that I'm connected to the computer? I press Power+Volume Up and it does NOT instantly go to the screen it should, but brings up a Google logo and sits there forever.

Doesn't work in either case, it just hangs until the hard reboot kicks in.

I had the exact same issues. Turns out, I had to hold my volume button directly in the middle while holding power.

Glad you got it.. BTW.. I did-misread what you said and yes, you would have had a USB cable in. All these posts are running together of people asking for help and having issues. Mah poor brain is getting em all mixed together.

Great video! I might just be using this in the near future. I plan on waiting for the factory image (I just like having a full install on my devices when possible) instead of using just the zip file (that is if I dont get the update). Although if the update isnt showing up sometime soon then this is going to work for me just fine.

can't enterthe stock recovery since i instaled CWM. removing it would bring the stock back ?
for some reason its not working for me. im fully stock, no root, locked bootloader. my pc recognizes N7 adb host and goes into recovery, but when i write the command "adb sideload 03a4eaf95f73.signed-nakasi-JZO54K-from-JRO03D.03a4eaf9.zip" it doesnt send it and just shows me the help info for adb. any suggestions why?
Thanks in advance
Same issue, when I "adb device" it will sometimes show as "device" and other times as something else (don't recall but not device). I can get into recover via "adb reboot recovery" and then into "update via adb" but when I "adb sideload.....(see above)" it just runs through the different commands as if "sideload" is not an option? Followed the video to a "T" and nothing.....thinking about rooting and doing it the old fashion way but this is the first android device I've had that I've not seen a reason to root right away...maybe should just wait for the OTA?

While in stock recovery and in the "apply update from adb" screen, type in the command window "adb devices". It should say:
<your device serial number> sideload
If it does not, check the drivers in device manager. You may need to manually install it. I had to on mine.
Cheers qbking77, worked a treat.
First time I pushed using adb & after following your tut life is good. Thanks again!

You may be using an older version of adb that does not support the sideload command.

It should say 8sdgfs3JKSDBFkjk3 device or something like that. If it does not, you need to install the the correct driver.
My computer did not recognize my tablet at first. I went to this thread and installed PDAnet which installed the driver.

unplug the cable,
force reboot,
select FASTBOOT,
when it shows FASTBOOT (in red),
plug the cable to your computer, and it should change to FASTBOOT USB
.
1.57,
it remains highlithed in blue. it freezes highlighted in blue.
there you got it. i recorded what happens, if you have patience 2-3 mins.
ignore the cracked screen, i disassambled the phone to disconnect the battery, in hope of something would work after.. and did not matter for me if that i damaged it, i have new full housing with touchscreen for it.

Hello there. Me was given a Razr i XT890. If i turn on there only the "Warning Bootloader unlocked". I try to get in Fastboot mode or any other mode but i only stuck in this window or nothing. I dont even get a Batterylogo if i load with the wall charger. I put it on my PC but nothing happens. No new Device. No ADB. Nothing. Can i rescue the phone or is it only a paperweight?
Most likely a brick. U could try to do something with the xfstk flasher. Search it up, get the right files and hope it works
It's recoverable!

The first thing you should do is to see this video (https://www.youtube.com/watch?v=OTzaiwj-bGw) to install libusb on your computer (if you are using Win 8 or 10 you will need to remove the signing imposition on driver installation - search for it).
The second action is to download the programs provided in this other topic of the community:

Then follow the instructions:
1 - With the cellphone turned off, connect it to the pc by the USB cable holding the camera button, when vibrate, release. (The green light should be on).
2 - Run xFSTK-SoC-Driver-Setup-1.0.3.exe and follow the instructions. (Your cellphone will probably turn on and will be locked on the bootloader unlock warning screen).
3 - If the phone has turned on, it will remain locked, then press and hold the camera buttons + volume down + power button. (It should vibrate, then release the buttons, if all goes well it will turn green).
4 - Run the unbrick.bat, when you start the prompt keep holding down the volume button of your cell phone. (If all goes well it will restart, continue with the down volume button pressed, when on it should enter fastboot mode.
If you get here and he gets into fastboot mode, CONGRATULATIONS you got it. Now just install the rom via RSD Lite. (Look up if you do not know)
Remember that your cell phone must have the bootloader unlocked for installation of the factory rom.

I hope I have helped!
Great! People from everywhere thanks you a lot.

Hey, Bruno! You prolly don't open this forum anymore, but I'm trying to unbrick a moto razri that has this exact problem. I'm trying to follow the steps you sent, but it's pretty confusing, since some of these files are from 2009 or from some other windows like XP, Vista, or 7, and I'm trying to do all of this on my Windows 10 machine. Can you please try to update these steps? Thanks!
Dear XDA users,
I want to unlock my (GFs) Z3c and I am unable to access the bootloader.
Starting the phone with Power + VolDown does not do anything, as long as the VolDown is being held, the screen stays black. When powering up the phone with Power and hit VolDown right after that, there is a loop where the phone shows the Sony logo and turns black each ~15 seconds.
Executing "adb reboot bootloader" shuts off the phone (the LED shows blue after that).
The device is a refurbished one with branding from "Telekom Germany" that we got as a replacement from our phone insurance after dropping the first one.
Is it possible that the bootloader is hidden somehow or missing/faulty?
What can I do?
I have working Flashtool and ADB on Win10 Pro (with disabled driver signature checks).

1. Check if bootloader unlock allowed = yes, (open dialer, enter *#*#7378423#*#* and go to service info-configuration).
2. If yes, unlock bootloader - https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader (backup ta if you want - https://forum.xda-developers.com/cr...versal-dirtycow-based-ta-backup-t3514236/amp/)
3. Flash recovery: install official TWRP app, select recovery for Z3c, download and flash on computer with terminal command 'fastboot flash recovery'.
I confirm the same issue as OP. I've downloaded the respective firmware and have confirmed via the service page that the bootloader is unlocked.
Now I'm trying to boot into fastboot via "adb reboot bootloader" and my phone looks like it turns off (no notification lights). When I type "adb devices" and "fastboot devices" both are blank ("adb devices" could find the device prior to the reboot command).
I also tried the Sony instructions and pressing Vol Up + Plugging in USB and this also has the same result as above. Not sure what to do next.
Update: I'm using Windows 10 and the problem was that it would not install the unsigned drivers that came with Flashtool. Once I rebooted Windows in troubleshooting mode (Shift + Restart) and disabled the signed driver requirement, Flashtool installed correctly. I reflashed the phone for good measure and now following the normal steps fastboot devices picks up the phone.
SOLVED
Hi there.
I had my couple's mobile rooted with Magisk and MIUI Global 10.3. Once wanted to update twrp and the issues began. Actually the mobile isn't rooted but with unlocked bootloader, apparently.
I list the issues down below:
1) Trying to install twrp with fastboot by CMD, pressing enter after the command the cursor just blinks and nothing happens. At first it showed "waiting for device", so I installed adb drivers and the mobile appeared in Device Manager. It run once up to "sending 'recovery'" but not farther. The mobile was connected in fastboot mode indeed as well as in usb debugging but couldn't activate oem unlock as it stated it as unlocked and the option was dimmed.
2) Tried to unlock the mobile with Miflash_unlock and the phone was recognized, but the tool checked the device up to 50% and then showed that it Couldn't verify the device.
3) Then I tried to make a backup of the user data and doing a Hard Reset from settings. It went forward up to reboot, so I did, then it entered in fastboot mode for a few seconds and it powered off. Rebooted the phone and it was up and running as if nothing happened. So I cannot make a hard reset.
4) I can't enter the recovery too. If pressing volume - and power on it enters in fastboot mode. With volume + and power on it does the same With recovery enter tools isn't possible either. It seems as it's been corrupted.
5) I've just tried to flash the Global_8.0 rom with MiFlash 2019.12.6.0 and on the progress line it says "echo Mismatching image and device" How? I'm sure its a Mi Mix 2 'chiron' Rom, so... Anyway, I start to flash and the tool seems to progress but it never ends. So I disconnect the phone, reboot, and it keeps untouched running as before, OMG
6) On top of that I can't update android by OTA, as it gets downloaded, then reboot, then enters fastboot mode and after few seconds it powers off as before, and powering it on afterwards shows that it couldn't be updated
So I don't know what to do next. However, the mobile runs apparently ok.
May someone lend me a hand, please?
Thank you.
SOLVED: The Xiaomi Mi MIX 2 is up and running with the last firmware installed. The issue was that, as I build a new PC lately, I connected the phone in fastboot mode to the front USB ports, which are 3.0 version, and you need a 2.0 USB port at most, causing errors in MiUnlock and MiFlash.
