Changed the DPI now wont boot? - Nexus 7 General

Hey guys I just changed the DPI on my Nexus 7, now it wont boot, it sits at a greyish/black screen, going into recovery it sits at the google screen.
anyone able to help please?

did you edit the build.prop manually or did you use an app?
basically you should just reboot into cwm and run a restore of your last backup

Plug your USB cable into a computer, you don't need to run a program just have it plugged in, boot to boot loader with power + vol up + vol down and then choose recovery with the volume rocker.
Inside recovery wjpe data, cache, dalvic cache, and system and restore the nandroid backup from before you changed the DPI.

[Q] CM7 loop boot animation no power button

Here's my dilemma. I flashed CM7 RC4 to my n1 last night, now it is stuck in a loop of the boot animation and will not proceed any further. I'd boot into the bootloader, but my power button's been dead for a month, ADB won't recognize my phone to reboot-bootloader. Am I boned?
Pull the battery, connect your phone to a charger then hold the trackball while re-inserting the battery. Make take a few attempts, but it should eventually boot into fastboot. You could also hold volume down instead of the trackball if you just want hboot...

Now i'm getting the battery indicator flashing green/orange. I can mess with it until I eventually get it charging solid. Is there any quick workaround for this?
Now I'm in fastboot. Is there a way to get into recovery without power button?
Is your bootloader unlocked?
Sent from my Nexus One using XDA Premium App
yes. indeed it is. If it helps, I have the latest CWM installed.
Place a copy of your recovery image in your sdk tools folder, connect via fastboot and type:
fastboot boot name-of-recovery.img
(use the real name of your recovery image)

What steps should I take to force recovery mode if I have an EVO? I've tried holding volume up while power but it vibrates three times and does nothing. I'm stuck in the boot loader screen.
*-**EDIT
I was able to fix it doing a hard reset.
Turn the power off. If your HTC EVO 4G is frozen, pull the battery out and reinsert it
Hold the Volume Down button
Press and release the Power button
You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock
Select Clear Storage by pressing the Volume Down button
Press and release the Power button
Now simply confirm your decision: Volume Up for YES and Volume Down for NO

vol- & power doesnt boot into recovery

I rooted my 2X with super one click and installed CWM 5.0.2.0 using rom manager. I used the rom manager to reboot in to recovery for the first time, then I tried to boot into recovery by holding down vol- & power but instead of taking me to recovery it gets stuck at LG logo. I had to remove the battery to reboot the phone.
Any one got a solution for this.
It works now, I just kept holding Vol- & power button for around 10 secs after the LG logo apeared then released and it went to recovery.

I m already using rom manager.

It isnt rom manager is an app that lets you quickly reboot to CWM witput pressing any buttons
Yup, this was the first time I tried to boot into recovery manually. These apps are no use once you flash a new baseband using smartflash as it will do a full wipe of the device and you have to enter recovery manually.
Sent from my LG-P990 using xda premium
the tricky part is to release the power button at the right time, or immediately the first menu item (= reboot system now) will be executed.
You are absolutely right, I just released the buttons as soon as the LG logo appeared. As a result it gets stuck and I have to remove the battery.

hisham i did the same but my phone is stuck on the logo too....i tried to boot in recovery mode but its still stuck/////
Try booting into recovery again, this time hold the Vol- and power button a little bit longer (maybe 15 or 20 secs) and also try updating CWM to the latest using ROM Manager.

I dont have a clue whats going on but you can use smartflash to restore the device to factory. If anyone has a better solution please tell.

Give this a try
Same here
I have almost the same problem. That is, when I try booting to recovery from ROM manager, my phone is stuck on the LG logo (red one), but when I try holding vol- and power button to boot into recovery it just does a regular boot.
I recently went from CM7 to a new stock ROM using Smartflash tool, but I want to change back due to lack of apps available.
I have also installed CWM from the AIO-toolkit for P990, but this didn't help. I still cant boot into recovery.
Does anyone have a solution to this? I want to flash a new ROM rather than the stock LG one.
with CWM 5.x.x.x you have to push and hold both power an volume- and after CWM screen is started DO NOT release the power button first but release the volume- first (keep powerbutton pushed all the time) and push volume- once so it does not choose the reboot option.
Then release both buttons, "scroll" with vol- or vol+ and "enter" with powerbutton
First time i used the CWM5.XXX the "reboots" did drive my creazy
Occurred to me too and solved flashing TG v28g (which has root and recevery attached).

[Q] Help! Soft brick on SGH- i957 LTE

I bricked my tablet after I tried to change my font using font installer by jrummy?
It asked me to restart for changes to occur so I figured if I restarted on my own it would work the same way so I hit cancel. I restarted about 1 minute after I hit cancel.
My tablet will boot up to the AT&T "Rethink possible" screen (after the animation).
It will get stuck there with a pattern of light vibrations between a couple seconds each.
Currently running the stock AT&T ics rom posted in the android dev section for i957.
I've tried to boot into recovery but the Samsung screen doesn't come up until I let go of the buttons therefore leading it to reboot again.
Also tried to go into the emergency download mode ( power, up, down) but it didn't work either.
I appreciate all and any advice, please and thank you!
My device is rooted if that wasn't already implied, I will provide any other details if needed, please help!!
Thanks again!
Are you sure you can't get into recovery mode? Hold power and volume up buttons, etc. Does Odin recognize the device?
Do you have a custom recovery, and if so which one, or is it stock.
Sent from my SAMSUNG-SGH-I957 using xda app-developers app
keep trying to get into download mode or recovery. should be possible. the font change will not affect recovery.
I was also performing a backup with titanium backup when I restarted does that make a difference?
I have clockwork mod recovery.
From experience, I can only go into recovery if the Samsung logo pops up for a milli second and I let go.
I actually haven't tried to see if Odin recognizes my device but I assumed if I couldn't go into download mode it wouldn't.

Were you restoring apps from a honeycomb Rom? That will cause a soft brick.
Sent from my SAMSUNG-SGH-I727 using xda premium
If you can get into recovery do a factory reset. That should get you out of a soft brick. You'll have to re-install your apps though.

I never use tibu anymore
Sent from my SAMSUNG-SGH-I727 using xda premium
Didnt see if you worked your way out of this or not. You may have to hold 3 finger salute (power, up, down) for up to 16 seconds. My guess is that covers the 8 seconds to reboot through any hang up plus up to 8 more to boot to menu.
Still no luck, the computer is not detecting my tablet.
I also wasn't restoring, I was just backing up my data. I'm letting it charge for now, anyone know what else I should do?
I really can't enter recovery OR download.
**** UPDATE****
Okay guys I finally fixed it. Will post details if anyone is still interested.
I'd be interested in the details.

I couldn't go into download mode until I did some weird trick with the buttons.
I had to hold the 3 buttons ( power, vol up, vol down) for a couple seconds.. like 6 seconds
THEN hold power and vol up for 2 secs
THEN back to power, vol up, vol down.
I did it by accident cuz I was frustrated but it ended up working so all is good
Thanks for all the help guys!!

Try'd to flash my LG p880

Hi everybody,
First sry for my bad English.
I Try'd to flash my LG with a new rom.
But I couldn't mount system, so I can not format system. I've got 10h with root access. Any tips or something else?
Sent from my LG-P880 using xda app-developers app
Can you be more specific please, what rom did you tried to install? What problem do you have with your phone?
Sent from my LG-P880 using xda app-developers app
Why would you want to flash another ROM if you already have the latest?
To "mount" the phone, you have to plug it to the PC without the battery and while pressing the Vol - key
I tried to install the custoNexus rom. For that (instructions) I have to wipe data and format system. So I tried this.
I used the lg recovery app, boot into recovery and wipe data, after that I tried to format system and get an error that the system couldn't be mounted.
Once again I'm sorry for my bad English

Turn off your phone, press and hold the VOL - key then turn on the phone while holding the key...
Once you see the LG logo and the phone vibrates, you can let go... it will enter the recovery mode... then you'll see tha "wipe data" option... select that with the power button... confirm once again and then reboot...

I don't know very well what you're trying to do but, if you're talking about reset the phone to factory settings just turn OFF the phone (with the battery), press "Vol-" +"Power button", you'll be in Android Recovery System".
Now select wipedata/ factory reset and hit power button, in the next menu select "yes" and hit power button again.
Wait untill you have the first menu and select reboot and hit power button.
If you're trying to install any rom from Dexter, pay attention to the tutorial. If you need ask him for help.

INSTRUCTIONs
Factory reset / WIPE before you install, as during installation of this ROM it will only install and clean system partition automatically. you are responsible for factory reset .
Alternatively - use original recovery where you factory reset as well. (VOL- + powerOn, remove usb cable, or you get to wrong menu)
Install the release using latest ClockWorkMod , using "install zip from external sdcard". this is a regular "update.zip" type of install.
This zip do not include the CWM installer i made, so install it seperately, but do NOT press install cwm, just use it to start recovery.
If you want some default apps removed, just delete those in the zip file. you find them these in the /system/app directory
Settings panel might be divided in 2 rows. If you like the old phone 1 row panel, enter ROM control -> General UI -> enable dual panel , and enable it. exit setting and reenter and unclick it. and you are done.
