I bought a nexus 7 today, rooted it no problems, but i changed the pdi settings to 160 to see if i could get the tablet ui, and now it wont boot fully, i can get into recovery and all but it wont boot past the google splash screen :/ HELP!
Here is stock build.prop for JRO03D, you can try pushing it via adb only other thing I can think of is complete reflash with the factory image
good luck
Is there a way to get the image onto the table in recovery?
Pretty sure you flash that image in fastboot
Sent from my Nexus 7 using Tapatalk 2
yes you use fastboot to flash the image via cmd prompt on your PC
I apologise, I've never had to use ADB or fastboot before, do you just give the file location and then it'll flash it on the tablet?
if you can get to recovery, try plugging the tablet with cable to a pc and mount the storage and move a rom over to it and flash it?
i dont have a nexus 7 yet but that would be my fix for a phone

adb push
adb is enabled in clockwork recovery. There's no way to mount the "sdcard" in recovery like you can on devices that have a physical SD card device.
I used nexus toolkit worked great!

I Did something really stupid, I have a Nexus 7, rooted, unlocked, went to twrp and did a back up of the stock rom, it said successful, then rebooted used the rom, everything perfect but I had tablet mod on it, decided to go back to full stock, booted to recovery, wiped everything, tried to restore and my backup is not there, and I deleted the rom as well, so now I have no rom to flash and I'm stock in recovery, anyway to push a rom into the nexus in recovery or bootloader? I tried flashing it with root toolkit 1.5.5 but it doesn't find the tablet,(all the drivers are installed), any and all help is appreciated...
Your PC won't see your N7 in Android because you haven't turned on USB debugging, and probably can't now.
You should be able to push an updated TWRP in fastboot that will see your 4.2 backup. The older version can't find its backups in 4.2,as you've discovered.
I'm not the lowest of the low, but I am the slowest of the slow.
I did have it on, I can see the tablet from control panel, but when I run the kit it says adb device not found..

The drivers will let your PC see the N7, but you have to be in USB debugging for ADB to work. You lost it when you wiped your system, as the failure of the toolkit to see the ADB proves.

USB Debugging doesn't need to be on for ADB through recovery to work.. Why would it? The system isn't even on it is in recovery.
Try the toolkit in fastboot.

when I'm in the bootloader it says it's in fastboot mode, but the toolkit wont find it!
I running recovery 2.3.2.1
tried adb sideload as well and it says "cannot read sideload" any ideas? getting a little crazy here..
Can anybody give me specific commands in ADB or fast boot I'm an idiot when it comes to that, on how to try to push a ROM into the device so I can flash it from recovery, or maybe a link to where I can read about it, I would really appreciate it..

While in recovery, type in the following:
Code:
adb push <name of ROM zip> /sdcard
You need to open a command prompt window, change directories (cd) to your Android SDK - platform tools directory, and to make things easy, move the ROM zip file into that directory as well (platform-tools that is). Then type the adb push command above.
EDIT: This puts the ROM zip on the root of your sd card (/sdcard). I have a ROM folder on my sd card, so I would type:
Code:
adb push <name of ROM zip> /sdcard/ROM
This just shows that you can push a file into a folder on your sd card.
I have a new rooted and unlocked Nexus 7. I flashed a kernel and can't get past the nexus boot screen. My battery is about dead. What do I need to do! I have the tookkit, but I can't get it to do anything! Please help! My battery is almost gone!

Battery just died. I could not turn it off. Everytime I tried to, it booted right back up. I was in recovery, but as I said, I have no roms or kernels to flash. I tried to mount the device, but was unsuccessful. I clicked mount system and nothing showed up on computer. Couldn't click mount sd card.
Someone please help me.
Always make a back up... we'll starting now
Let it charge, try again to get the proper kernel and flash in recovery. If it won't let you mount SD to transfer, extract the boot.img from the ROM you were using and flash via fastboot.
fastboot flash boot boot.img
fastboot reboot
See what happens
Sent from my Nexus 7 using xda premium
Can you please explain how to do that? I am new to the Nexus. I can get into Fastboot and then recovery. But how would I flash via flashboot. I do not see that option.
Edit
I do suggest reading up a bit on android or you are bound to find yourself in these situations. Also try and stay away from toolkits, you would already know what to do if you weren't using them
Download rom of choice to computer
Extract the boot.img from the .zip
After you charge nexus a bit, plug into computer and boot into bootloader
Open command/terminal on computer in the same location the boot.img is and type
fastboot devices
If you get 'waiting for device' you need to download the proper drivers, and or need to change directories to where fastboot.exe is located on PC, or just make sure you download everything from the platform-tools in the sdk and I recommend changing the path in environmental variables to include adb/fastboot
If you see your serial number proceed
fastboot flash boot boot.img
fastboot reboot
this should replace the kernel causing your boot loop with and all is well

Learned that the hard way! So if I download the ParanoidAndroid ROM, just extract it and get the IMG file?

Took the img from the ROM and fastbooted it and it wrote, but tablet won't load past Google screen...
So the only thing you did to cause it to get stuck originally was flash a kernel? If that was it and then Fashing the right kernel doesn't work and recovery won't let you Mount to put a ROM on SD, I would flash one of the official full ROM updates through fastboot.
There are a bunch of them posted here just grab one and flash it and she what happens

I tried updating my nexus 7 to 4.2.1 and i thought everything went okay but now adb doesn't recognize my device in fastboot and i can't boot up my nexus 7 because everything got wiped on my sd card. I can boot into recovery but i can't mount my sd card either. It tells me there is an error. Apparently there is no OS installed. Any help is welcomed.

You can boot into the bootloader, and use fastboot commands to reflash the stock Android 4.2.1 OS.

You can't use adb in fast boot . Reboot to the boot loader. If you type 'fastboot devices' in fast boot your phone will show

I had the same problem.
What version of adb.exe Ade you using?
The latest is dated sometime in November this year. If it's earlier than that, download the SDK from android development site and use newer version of adb.exe
That should fix the issue...
Sent from my Nexus 7 using xda premium
From bootloader use fastboot commands, from recovery use adb commands.
You can't do adb commands in fastboot mode. To do adb commands you either need to be in Android or in a recovery.

Stop... MUFFIN TIME!!!
If you have twrp recovery installed you can boot to recovery and use adb sideload.
So just download a rom on your computer boot to recovery and sideload the rom to your device and then install it.
Not sure if this can be done with cwm though

Please help, I downloaded ChameleonOS Rom for Mako and I was on PA. I did a backup in TWRP and after I wiped data and cache I tried tp flash CHAOS ROm. It said success but it won't boot passed Google and If I try to restore PA it says failed and now I have no rom to flash to boot up and also I can't turn on debug to use ADB.

i'm not on twrp at the moment but you may be able to try this
you may also try the nexus toolkit
Nexus 4 toolkit says device not found when trying to push file to device. It shows serial under fastboot mode but not ADB Mode. Is that because I can't turn on debug?

hmm... can you try setting the current status to "Soft-Bricked/Bootloop" and do the Flash Stock + Unroot? might be able to get you back to square one.
if you can get into twrp you might be able to run adb commands from the recovery even if you didnt have it enabled before using the toolkit.

not sure what you're trying to do, but if you just want to get the device up and running again..
- Download recovery with sideload
- Go into fastboot
- Use CMD to navigate to your Nexus Toolkit folder,
- Execute " fastboot flash recovery recovery.img ", assuming the image you downloaded was renamed to recovery
- Go into recovery, choose flash with sideload
- Back to CMD, type "adb-toolkit sideload *zipnamehere.zip*" , assuming your adb is named adb-toolkit
reboot, profit.

It says fastboot is not recognized as an internal command
In twrp, it keeps saying starting adb sideload feature
i posted this in another thread. try this...
1. First make sure that you have fastboot driver installed.
2. Power down your Nexus 4 (hold the power button until it shuts off) before rebooting into fastboot mode. You can do this by holding down the the Volume Down and Power buttons simultaneously.
3. Connect your device to your computer. Open up a terminal or command prompt, and navigate to the folder containing the fastboot program.
4. Type fastboot devices into the command line, and you should then see your device’s ID, which means fastboot is setup correctly. if not, check to make sure Google Nexus 4 drivers are installed correctly.
5. now open Nexus 4 toolkit and Flash Google Factory stock Rom. Once you are back to stock continue on from there...
Good Luck!

my bad, it's fastboot-toolkit. But since you have a recovery with sideload already, just download a rom that's working, put it in your nexus 4 toolkit folder, rename it to flash.zip, and type in CMD
"adb-toolkit sideload flash.zip"
Thank you all for your help. What I had to end up doing was extracting the factory image and flash boot, system, and use data IMG files manually with nexus 4 toolkit. My Nexus 4 is alive. Again thank you all very much

Hi,
i unrooted, unlocked and installes cwn via nexus 7 utility tool 4.0 and flashed the stock 4.2.1 rom. after reboot the nexus 7 get stuck in the bootloader. if i try to boot via"start" button it says "unable to boot" in the upper left corner. booting into bootloader mode works. booting into recovery mode works too, but the nexus 7 is unable to mount the sd card, the cache and so on. i tryed to reflash the stockrom with the nexus tool but when it says"all done, the nexus will now reboot" nothing happen. i tryed to reflash stock rom with the instruction in this section with adb and fastboot. it get stuck after giving the first command to reboot into fastboot. what can i do to get the nexus to work?
Have you tried the sideload command? Select 'install zip from sideload' when connected to your computer, and from cmd on your computer type adb sideload rom-name.zip
