[Nexus 7 Android Development] Kaangaas:
Hi!

I'm having a slight problem when i'm trying to return to stock. I've been trying the following sequence:

1. fastboot erase boot
2. fastboot erase cache
3. fastboot erase recovery
4. fastboot erase system
5. fastboot erase userdata
6. fastboot flash bootloader bootloader-grouper-3.41.img
7. fastboot reboot-bootloader
8. fastboot -w update image-nakasi-jzo54k.zip

Step 1-5 executes with an "OKEY".

On step 6 I get the following

sending 'bootloader' <2092 KB>...
OKAY [ 0.277s]
writing 'bootloader'...
FAILED <remote: <Unknown error code>>
finished. total time: 0,410s

Although when I'm in fastboot on the nexus it says "PRODUCT NAME - grouper" and "BOOTLOADER VERSION - 3.41". When I execute the command it also says "Signature match" in the top left corner of the nexus. So it seems like the bootloader is the right one, dosent it?

Step 7 is also works fine.

Step 8 is where I got problems, when I execute the command I get the following output

archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
--------------------------------------------
Bootloader Version...: 3.41
Baseband Version.....: N/A

sending 'boot' (4896 KB)...
OKAY [ 0.615s]
writing 'boot'...
[B]FAILED (remote: (FileWriteFailed))[/B]
finished. total time: 3.586s

What does the error mean and how can I fix it?

I've also tried unziping the zip file and flash them individually using

fastboot flash boot boot.img

sending 'boot' (4896 KB)...
OKAY [ 0.624s]
writing 'boot'...
FAILED (remote: (FileWriteFailed))
finished. total time: 0.650s

I've tried it with recovery and system and in different order but I get the same error on all the commands.

I've also tried switching USB-port just to be sure but that didn't work either.

I forgot to mention that I can't boot the device anymore, I can only access fastboot otherwise it just bootloops on the google logo.

Any one that can help me solve this?

I apologize for not maintaining this thread as I should have as I have been crazy busy lately and I am not sure what is going on with the OP. When I go to edit it, it shows the full post, however when I hit save, it just shows the abridged version without all of the instructions. I don't know why it isn't showing the full post. Anybody have any ideas??

Nevermind...I figured it out. All fixed.
[Nexus 7 Android Development] ngoralph:
try downgrading your bootloader or do the process on other pc
[Nexus 7 Android Development] chris.wueste:
I had the same problem and as stupid as this is going to sound, I uninstalled the drivers for the N7 and ADB and Fastboot. I wanted to start from a completely clean slate. I reinstalled ADB and Fastboot first and then the drivers for the tablet. I then redownloaded the factory image and voila...it worked. Must have been some sort of corrupted driver or something. Haven't had a problem since. Hope this helps you. Seems to have helped a few other people as well.
[Nexus 7 Android Development] Kaangaas:
Thx guys, im going to try to install ADB and Fastboot on an other computer and see if it works :)

I think you should edit the 3rd to the last line of the OP to 4.2 ;).. anyways, thanks for the guide... :o

Thanks for posting this guide. I was stuck at the X for a while, but I force-rebooted and wiped /data - it's working fine now, although I hate the lockscreen clock.

Can I flash the factory image of 4.1.2 after I've upgraded to 4.2? Or is there anything that I should be worried about?
[Nexus 7 Android Development] wojtek_pl:
Yeah, since I heard a lot of bad things about 4.2 could You leave the link to 4.1 (4.1.2 perhaps?) somewhere in Your post?
[Nexus 7 Android Development] gkarthik16:
You can get the factory images from Google developers site.

Help!!

Oh noes, my first semi-brick :S

I was messing around with multiboot, but my CM 10.1 won't boot, and ubuntu won't get past ramdinit or something.

When I try any fastboot command I get

< waiting for device >

I have tried as root, under superuser and sudo :S

I am in the correct screen (the one with the start, reboot bootloader etc and the green droid with blue buttons)

Please can someone suggest solutions as obviously I want to use this device in the future :S

I'd really appreciate any tips or ideas, no matter how silly sounding :)

:S

I may be panicking slightly :S

Praise the lord for Errors/changes. I found an old TWRP backup under sdcard 0 for some reason :). I have managed to install it as a rom now too :)

Re: [Guide] Returning to Stock and/or Unbricking your device

[Nexus 7 Android Development] digixmax:
Just take a peek inside the 4.2.2 archive (e.g., using 7-zip) and you can see the content that will get flashed -- it includes bootloader-grouper-4.18.img.

Help Needed

Hey guys, I have a Nexus 7 WiFi only 16 gb model.

There is a problem with it. I first rooted it with the help of Nexus root tool kit and all was fine. Then I tried Cyanogen Mod's latest release but it was lagging and so I accidently restored my old backup but it didn't restore. Since then nothing is being able to mount.

E:Unable to mount '/system'

E:Unable to mount '/cache'

I tried to factory reset via command prompt but it fails to write cache.

Present condition is- The device loads the bootloader and then it gets to custom recovery.

I tried to flash stock rom via fast boot and it flashed boot.img and recovery.img but when I tried to flash system.img the following error is shown-

(check the screen shot)

Please help

:crying:
[Nexus 7 Android Development] VideoSavant:
I have a Nexus 7 2012 model with which I'm having "looping" issues. Note that these are not "boot loops," or at least not in the sense that I understand the term. My N7 tablet boots up normally, but after it begins loading apps and updating notifications, it will momentarily freeze and then reboot. These freezes vary somewhat, but almost always within 90 second to 5 minutes of loading up. Booting into Safe Mode will sometimes give me virtually unlimited uptime, but on other occasions it will freeze/reboot within a minute or two.

I rooted shortly after I bought the tablet but never loaded any ROMs. When I was running stock 4.2.x, my USB port broke, and then later the update to 4.3 zapped my root and TWRP recovery (and without a USB port, I wasn't able to restore root). I recently replaced the USB port (and I've verified it works for both charging and data). However, I'm stuck and need some help.

I initially tried to fix my looping issue with the Nexus Root Toolkit. My initial goal was to just restore root and TWRP and go from there. No matter which of the methods I choose via the Toolkit, I am stuck on 4.3 with the looping behavior continuing. I have also tried to fix this through the ADB method detailed here -- this is more difficult, as I have to race against freeze/reboot countdown, which varies from maybe 90 seconds to as much as 5 minutes. But in both cases, I'm able to complete the Toolkit steps or work through all the ADB commands, but I'm still stuck where I started.

On a couple of attempts, I was able to successfully go through the Unlock, Root + Custom Recovery steps of the toolkit, and twice I have been in TWRP. The second time I was in TWRP, I tried to do a Factory Reset and also a Full Wipe, but when I rebooted the tablet, I was still in my old version of 4.3, with all my apps and the freezing/booting issue. This seems to be a recurring theme with both the Toolkit and ADB methods -- although I'm getting real-time feedback that partitions are being deleted and recreated and that the system is being loaded etc., it doesn't appear that any files or configuration is changed.

It's like every day is Ground Hog day.

I know that you guys can't help me with the Toolkit specifics related to my problem, but at this point I'm just looking for general guidance. Obviously something is seriously hosed (or I'm the worst follower of instructions ever), as nothing seems to be able to change the freeze/looping situation I'm trapped in.

Any ideas?
[Nexus 7 Android Development] mattsolberg:
I am having this exact same issue. Have you, or anyone else, been able to resolve it? I've tried fastboot, I've tried wiping partitions in recovery, I've tried a factory reset in recovery, and none of them actually delete the data or flash new data. Just continuous reboots about 10 seconds after the launcher loads.

Help!
[Nexus 7 Android Development] VideoSavant:
I haven't had any luck getting any solutions, though a few guys have pointed me to other threads that I'd already seen and followed. I am now thinking that this is a hardware problem, as the key obstacle to a fix appears to be the inability to overwrite or change current system files.and partitions.

I'm still hoping for a fix, but I don't think I'm going to send my tablet in for repairs. I already sunk $65 in it to have the USB fixed, and even if I knew what the specific hardware problem was now, I wouldn't pay even another $50 to fix it. I also own a Nexus 7 2013, and was only looking for the 2012 to be a fallback.

But I'm not ruling out a miraculous software fix, courtesy of one of the many experts here at xdadevelopers...

Likewise, let me know if find a solution to your problem (and possibly mine). Good luck.

LPM Rom can brick the phone or its fixed?
[Galaxy S II Q&A, Help & Troubleshooting] MemoryController:
It can send your phone to bantown
[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
Nothing is 100% safe, but stock XWLPM ROM is safe.

Only when injecting CWM and wiping with it, may brick your phone.

I have flashed XWLPM twice, first with CF-Root v5.6 for XXLQ5, and then as Pre-Rooted version from liquidperfection.

With CF-Root I had CWM recovery, and wiped cache and Dalvik cache wihtout any issues.

So, if you only use stock recovery or permanent CWM of a "safe" kernel, then XWLPM won't brick your phone.

Anyone with a galaxy S3 try the following. Open up sms and instead of typing in your text use google voice.

Hey there guys, im not super phone savy although I can follow simple instructions and know the android OS fairly well. However i'm not super familiar or confident in the leaked/beta ROMS I hear about sometimes. I recently noticed on GSMarena that my GS2 is supposedly upgradable to 4.04. Any suggestions or recommendations on the most recent/reliable/stable ICS build to try? Also will I lose anything by upgrading? I've been told the kernel will no longer be rooted [which is OK I think] but do I lose my unlock as well?? Since im on Rogers and it's originally a Bell phone, I just want to be certain I can still use it if I upgrade. Any help would be great. My info is as such:

Phone Model - GT-I9100M

Android Version - 2.3.3

Baseband Version - I9100MUGKG2

Kernel Version - i9100jpkg2-cl342890root@dell104#2

Yes, you'll lose root, but no, you will not lose your unlock.

[Sprint HTC EVO 4G LTE] detwa1:
Try wiping everything including factory reset then reflash rom.
[Sprint HTC EVO 4G LTE] afgomar:
I did do that. Idk what the problem could be
[Sprint HTC EVO 4G LTE] Badious:
Mine does this as well. I talked to HTC and they said if you don't LTE in your area, Sprint LTE that is but have Verizon LTE, your phone may be trying to latch on to the Verizon LTE, and since it can't quite connect it attempt to push more power to the LTE antenna to get it to connect, in doing so, it eventually pushes it pass a threshold and causes the phone to reboot. Apparently the issues seems to be popular in areas where there is no Sprint LTE and other LTE available. Sounds like a software issue on HTC's end, that will hopefully get fixed.

For now, you can try and go a *#*#4636#*#* and change your network to CDMA Only or EVDO Only and see if that keeps it from rebooting. (when you change to CDMA only, make a call right away otherwise you might not get incoming calls or texts)
[Sprint HTC EVO 4G LTE] afgomar:
