[Q] Nexus 7 2012 wont boot - Nexus 7 Q&A, Help & Troubleshooting

Hi guys, I'm not sure what I have done wrong here.
I am not new to rooting and flashing so have already checked Google ETC for a solution for this but I cant seem to get it fixed.
I was rooting my nexus 7 the other week and ended up in a situation where I have no ROM on the tablet, I cant mount in recovery and I can only get to the bootloader and recovery - I did have slimkat on there but it aborted installation each time i tried to flash so thinking that it must be corrupt, i formatted the SD card - wasn't the smarted move I made as no I have NOTHING on the SD card at all and can't seem to get anything on there.
I'm not sure if this is a problem with the bootloader, if it is I am unsure of what to do because the only one I cant find is 4.23.
If anyone could give me some hints of how to get around this or push me in the right direction that would be much appreciated.
Cheers guys!|
FIXED!! I don't normally like doing it but desperation pushed me, I used wugfesh toolkit and everything is fine now Cheers

Please, help a n00b. I think I broke my Nexus S 4G

Let me first start off by saying that I am on a Mac.
I used these directions to get my phone unlocked and get ClockworkMod Recovery or whatever running on my Nexus S 4G.
I then loaded Cynogen onto my SD card, booted into Clockwork, wiped my phone, then tried to install Cynogen. It failed- it couldn't install boot.img or something.
Now, when I try to boot up my phone, it just shows the Google logo with the unlocked icon below it. It never successfully boots. I can still get into Clockwork Recovery, but below every menu section over the logo, it always shows some error like
Code:
E: failed to something something /cache
Can you guys please, PLEASE instruct me on how to get my phone working normally? I don't need it unlocked, just running the stock OS.
Anyone who can successfully help me do this on a Mac will receive a nice PayPal donation if they wish.
Thank you so much in advance.
And yeah, I know I shouldn't have been attempting this because I am such a n00b.

What version of CWM did you flash?
Pm me and we will use a chat service (aim, yahoo messenger) and I will walk u through it.
My suggestion of what I would do is this. Find a windows computer somehow. Go to the development section and look for the sticky about rooting the ns4g. Look for the link to flash the d720 back to stock. Download all those files to a flash drive. Take the drive to the windows computer and set things up then flash the phone back to out of the box stock.
Then you can go back to the Mac and do the root and 3024 cwm recovery and rename the sh file that puts stock recovery back in at boot time. After all this you can do what you want but I would suggest staying with the stock experience. This might be extreme to fix this but in my opinion, I wouldn't waste time trying to fix it, especially since you are new to this. It's like computers, yeah you could try to fix it but you could be opening a can of worms. It might take less wasted time putting it back to complete stock instead of f-ing around trying to figure out what happened and how to fix it. You could take hours trying to fix an install of windows that keeps falling on it's face, or you could format and install windows fresh and new in maybe thirty minutes. Which is easier?
CM7 will not work at the moment because it still uses 2.3.3, go find instructions for a 2.3.4 Nandroid. if you want though,i heard that supeaosp works on a ns4g.

Dude, you can't flash regular Nexus S ROMs on the Nexus S 4G.
Reflash the latest clockwork recovery.
Use fastboot flash recovery recovery.img
then...
Go to recovery, mount the USB storage, and put this zip on the usb storage:ROM
Go to recovery and flash that zip
here's the recovery that works. cwm and stock. How many times is this going to happen with new people and this phone in this forum section before a new subsection is made? We are going to be putting out a lot of these unnecessary fires with people making first time mistakes until something is done so as to not confuse them. Some don't realize that there are different versions of the same phone that aren't necessarily compatible with each other.
The way things are set up now, it isn't making this problem go away. I think that a different method should be tried if the current one isn't working too well. I'm flogging a dead horse now......
I'm looking to root my new NS4G as well -- and do it right the first time. On a Mac as well.
If the similarly-suited OP had issues I'm a bit more skeptical about my effort.
A separate forum might be necessary so people with the D720 hardware don't have near-brick experiences.

soooo....did the op ever get it running again? i wonder if anyone ever took up on his paypal offer

[Q] Roms wont load/pd15img.zip doesnt work

Hello everyone, First off I would like to thank all of those that have posted on this site and contribute to it.
Now to my problem. Let me share a little history of how everything started.
I first rooted my MT4G about a year ago, Tried to use IcedGlacier but it was not loading properly so I used cyanogenmod 6 I believe? I wanted to try IcedGlacier but It still was not loading properly. Then when I tried to restore it would not restore properly. At this point it appeared to be bricked but bootloader still worked but the PD15img file was not found. So after some researched I downloaded it and it restored my phone back to factory condition. Now I want to try other roms again because I'm getting bored of stock and attempting to load different kernels but this is where my issues are beginning.
As you can see in the attached photo that is what the bootloader looks like. I thought it was weird that next to hboot it says "HBOOT-0.85.2007 (PD1510000)".
(I tried to post the image but since I'm a noob I and unable. If you want to see the screen shot of my bootloader just message me.
I was thinking maybe this is a reason as to why now No other rom but the stock one will load. Also what is weird is that when it goes into bootloader it still says PD15img is not found but the phone will start up fine with the stock rom.
The phone remains rooted but No Rom or Kernel will Load and fully install.
When It loads roms it goes to install it shuts off and reboots into stock rom.
I tried to Use the PD15IMG.zip on the SD card to see maybe if it didn't load properly but it will begin to load with the blue bar in the corner but then after it goes all the way up nothing else happens.
I have been trying to look for answers but haven't found any real answers that help me fix my problem.
So if someone can help me I would greatly appreciate it.
The "no PD15IMG.zip" message is supposed to appear. When the bootloader loads, it checks the root of your SD for that file, and if it's not there, you'll get that message. Nothing wrong with that.
Since you're perm-rooted and running the engineering boatloader, you just need to make sure your recovery image is good. If you haven't already, download ROM Manager from the Market and use that to install a fresh copy of ClockworkMod recovery. From there you should be good to flash any ROM you want.
Thanks, I did what you said plus I realized when I was downloading the roms using a Mac and my Mac would unzip the file automatically and trying to compress it back to a zip doesn't work at all. But thanks alot for the help!
If the PD15IMG.zip doesnt work you probably dont have the part7-xxxxxxxxxx.zip file on your sdcard

[Q] ok i've got myself into a pretty sticky situation (stuck at google logo)

First off, I'm an idiot. I know this. But I would also appreciate any helpful advice that may teach me a thing or two about how to rectify my idiocy and prevent any future idiocy.
was fooling around with my n4 (which was on the cm 10.2 stable) and decided to give the 4.4 bandwagon a go.
downloaded roms and gapps ready to flash ect.. (ive done this multiple times before)
did a full reset (inc. system and external sd storage) from the android setting menu after backing up sd card and apps because i wanted a fully clean phone to upgrade
Then plugged in again but was dismayed to see that the pc and android memory wasnt clean, it said stuff was taking up storage space but the file system listed no files...?
so i went into recovery
and due to my tiredness and general lack of IQ, decided to format everything under the sun in mounts and storage (yes, this included /system)
and i dont have a nandroid (since i have the 8gb one and could never justify the space cost of a nandroid, plus i though i was pro at flashing)
and now my usb is acting up so i tried to fix that, uninstalled my drivers ect..
but realised for many driver installations especially for adb/fastboot drivers this requires you to plug in the phone and turn on debugging for the right drivers to install
so now i have a bricked phone which wont connect to fastboot and i dont know how to solve this and cant boot into android to mess around with adb and nothing on the memory like a backup or any seblance of an os.
Feel free to call me more of an idiot than I've previously mentioned. But i would GREATLY appreciate any helpful tips and would wish you all the christmas cheer i can muster
yours,

nexus 7 2012 - no hardware/baseband v#

i can get to the loader and recovery but think I am out of luck at this point. took it to ubreakifix and they couldnt do it either..
in a blonde moment I erased everything while in clockmod recovery. i still see some stuff on the SD and even had a rom stored but it fails to install.
no connection to PC (tried 3),, guess the abd drivers are gone from the actual nexus itself? tried installing drivers on PC all kind of ways but no go..going to pick it up tomorrow and see if somehow linux mint picks it up but doubt it..
any hope? I got a miscro usb adapter but nexus of course wont read anything from there unless there is a rig?
thansk in advance

Can get to CWM Recovery, but can't sideload

So, I can't remember what I did to this device, exactly. I got it already in a bootloop. I had seemingly fixed it for a few weeks, but then it started rebooting randomly and then eventually got into another bootloop. I can't remember if that just happened one day or if I was trying to fix the random reboots.
I stopped working on it when a family member gave me their old Nexus 5X. But the other day my Nexus 5X entered into a bootloop because of its well known hardware problem (I think anyway, I wasn't doing anything that should have bricked it). So I decided to pull out the old Galaxy s5 and see if I can fix that instead.
Normally when I flash ROMs onto devices, I do it when the process for the device is pretty well established. As we all know, Samsung devices aren't the easiest to work with. So I remember having to do a bunch of extra ****, download Odin and so forth.
By the way, I have the AT&T G900A version. I boot into recovery and see that it boots into CWM, thats good news obviously. I pick "update through adb". I run ADB through command prompt (btw, someone should update the guides on this site to mention that Powershell doesn't play nice with ADB commands, that was like 20 minutes of hair pulling frustration) and it recognizes the device. I wipe all the user data and cache etc and attempt to flash a custom ROM I found on this site: APTOS found here.
I get an
Finding update package. . .
Opening update package. . .
Verifying update package. . .
E:footer is wrong
E:signature verification failed
So then I downloaded the stock firmware ROM titled "SM-G900A 4.4.2 G900AUCU1ANCE Firmware.rar" and get the same errors.
So, obviously I am forgetting something. I know there are a lot of guides on here and the answer is probably out there somewhere, the problem is that most of those guides are for people starting at square 1 without CWM or TWRP installed. Can anyone help me from where I am at? I uninstalled Odin a while ago but could definitely reinstall it. Was hoping to do this from where I am at, since CWM is already installed.
Anyone have any ideas on what step I'm forgetting? Do I need to flash other things before the ROM? Should I just start completely over with ODIN and the rest of it?
P.S. I have more experience with TWRP than CWM but I remember having trouble getting TWRP to work but did manage to get CWM to install as an alternative.
Thanks in advance!
