Unlocked, rooted ok - couldn't boot into ROM

I just purchased the 32GB WiFi model and used this toolkit to unlock the tablet, then rooted it. This all worked flawlessly. I then used the custom recovery installed as an option with this toolkit (love the interface by the way), I wiped everything including both cache types and flashed SmoothRom 4.1. I was stuck at the custom loading animation for over thirty minutes, tried several reboots and never got past this point. At this point, I used the Toolkit to restore to stock and unroot, then went through the process again and tried to flash GlazedJellyBean and again got stuck at the custom boot animation. I restored to stock and unrooted then rooted again without the custom recovery and used ROM Manager to try flashing SmoothRom - again got stuck at the boot animation. I then restored to stock and rooted without the custom recovery which is where I am today.

What am I doing wrong? I have flashed countless ROM's for my Galaxy Nexus and never had issues before. The Toolkit was awesome, especially the restore to stock:)

I appreciate any help:)

I am having the same problem with file downloads from Google.im. I'm just trying to restore stock recovery on my Nexus 7, but the Toolkit always reports this failure, and I can't find any posts that show a solution for the problem.
[Nexus 7 Android Development] jpcalhoun:
tamanaco...you're problem most likely is that you have a custom recovery on your N7. An OTA will not be successfully installed with a custom recovery present. You have a couple of options...I prefer option 2, but here goes: 1) Use the Toolkit to restore the "stock recovery", download and install Voodoo Rootkeeper, backup root, then temp unroot and take the OTA update to 4.2.1. After the OTA has finished you can restore root with Voodoo Rootkeeper. Option 2...using the Toolkit restore "stock recover", unroot and take the OTA. After OTA has finished use the Toolkit to root and install a custom recovery.

Are you certain you selected the correct device and build? Those features have been tested extensively, but they are dependent on the end user selecting the right build.

[Nexus 7 Android Development] SteveC485:
You are trying to flash 4.1 on 4.2. Your custom ROM needs to be 4.2 as well. Same thing will happen trying to flash 4.2 ROM on a 4.1 system. Or for that matter a 4.2 kernel won't flash on a 4.1 system either.
[Nexus 7 Android Development] Alto101:
When I restored to stock I went back to version 4.1.2, Wouldn't I be able to flash another 4.1 ROM over the stock 4.1.2?

If not, what are my options for flashing a 4.1 based ROM?

Thanks!
[Nexus 7 Android Development] ALD3:
Used l.6.0 to unroot and lock to receive the update, as some said you couldn't get if rooted and my son took 4.2 update while rooted and screwed his nexus 7 up, wouldn't hook up to WiFi. Had to used 1.5.5 to fix his and then update. 1.6.0 worked great.

Thanks for all your time and tireless work, congrats on your N7. :thumbup:
[Nexus 7 Android Development] WugFresh:
Recognize that not all ROMs are packaged alike. Some devs write more sophisticated update scripts that allow you to flash them on top of any build. Typically if there are any prerequisites for flashing a ROM, like being on a certain build or bootloader version, then the dev will say so explicitly in the original ROM release thread. Therefore it is always good practice to read the OP carefully in a ROMs thread before flashing... That or be prepared to deal with things like bootloops.

That said, the toolkits "Flash zips..." Button in advanced utilities, with " file is on computer" has 'suggested' settings for ROM flashing and will automate the entire procedure for you. :)

[Nexus 7 Android Development] truth77:
Just bought my nexus 7 yesterday and been reading thru to see the easiest best method to unlock bootloader and root and this seems to be it. I updated fully to 4.2.1 yesterday, will this still work on it? And I don't see any instruction. Should I assume it will go to download mode for me once I start hitting unlock then root or did I miss something?
[Nexus 7 Android Development] 3kgt:
Wugfresh need help here plz.

I Bought a N7. Rooted stock with your 1.5 kittoolz. i had JB 4,1

Worked great no problems..

Then wanted to uppdate to 4,2

So i used ur tool (Back to Stock + unroot )

Worked great no problems.

Uppdated to 4,2,1 OTA ..

And yet again i did root with your Toolkit and used the android 4,2.1

No problems rooting.

BUT

Installing Bussybox it says installed but icon is still grey and nothing else added.

Tried to make a Nandroid backup but failed.. (But i Did enter TWRP 2 times)

Now suddnly i cant Enter TWRP, it says No command.

When i try from Bootloader to enter recovery it says no command.

I used PC and used Quick boot.. and room toolbox.

when i try to go manually buy Power and Vol + Nothing happens..

My N7 Freazed a cuple of times when i try to do this stuff.

I Re rooted again.. but no use..

Ihave just reinstalled and fixed all my setting and really dont have the will nor time to go over this again.. So whats wrong?

(Didnt use and also flash coustom recovery) ? can that be the problem!!! In that case why did it enter "TWRP" the first 2 times?
[Nexus 7 Android Development] vicw:
Since my previous post, I have been able to workaround the Toolkit inability to download from Goo.im, that results in these messages:

"Can't communicate with Goo.Im's JSON API, check your internet connection and try again.", and "Downloading recovery_stock_nakasi_4.2.0_JOP40C.img failed. Check your internet connection and try again. Please contact Wug if the problem persists."

I temporarily disabled Norton Internet Security on my laptop, and the script ran through with no issues. I'd like to home in on a specific firewall exception for the Toolkit, but for now, that is an easy solution
[Nexus 7 Android Development] WugFresh:
Ahh..! Thank you for posting back with this.. I was wondering what was up. The toolkit is using an autoit function called _InetGetSource at that step. Some google searching shows that a few other people scripting with autoit have run into firewall issues with that, however I wasn't able to narrow it down to some exception you could make yet. I will look into it more, or see if I can script that part in an alternative way. It also might help if within Norton you just reported the issue, then maybe they can analyze it and add the exception into their core firewall. I will contact them as well. Cheers. I will add this to the FAQs soon.

Not sure that's true.

I have TWRP installed and the OTA went on OK on both my Nexus 7 and Nexus 10.

I had to use VOODOO ROOTKEEPER to restore root and re-flash TWRP but all working OK.
[Nexus 7 Android Development] bennettg:
I need help. Noob mistake.

I had installed scotts cleanrom 2.0 (4.2 based) and wanted to revert back to 4.1. I have new bootloader. i couldnt get clockwork mod to work so I tried to flash the stockrom thru rom tool app. everything went bad, many error messages, etc. I'm bricked. i can only get to fastboot mode, not recovery.

so i'm now trying to use the toolkit to reflash the stock rom and start all over, but my windows box keeps saying "waiting for device". I think the adb drivers are not working or something, but when i try to go into the toolkit to start anew, it tells me i need to be in adroid and select usb debugging, etc. i cant do that so i seem stuck. the computer is not seeing my nexus 7 when plugged in by usb while it is in fastboot. any ideas?

thanks.

desperate noob.
[Nexus 7 Android Development] WugFresh:
USB debugging is just for ADB when your device is on. You just need your computer to communicate with your device in fastboot mode. Chose a driver solution, like #3, and stat from the steps that describe configuring your device in bootloader mode (for #3, thats step 7). Once your drivers are configured in that state, you can proceed to use "Flash Stock + Unroot" with can't boot up... and all will be well. :)

Lol I know that part that's obvious. I'm asking do I manually put it to download mode or will it do it for me once I start the unlock process?
[Nexus 7 Android Development] DanteGR:
Guys i want to unroot and relock my N7 for guarantee purposes.

Is it enough to restore the nandroid backup of my stock rom (4.2 since i already updated via OTA before rooting) and then hitting "flash stock and unroot" and after that "lock device" in the main menu of the NRT?

Is there something else i should do?

Many many thanks in advance :)

[Nexus 7 Android Development] 3kgt:
Idont think so!

I would use the Toolkit to get it back to stock and lock the N7 again..
[Nexus 7 Android Development] DanteGR:
That's what i said mate.

I will also use the NRT to get back to stock.

But are the steps i described above the right ones? In the right order i mean?

This worked just like a charme - so easy :)

Takes as good as no skills to use it - compared to rooting and unlocking bootloader on my Desire HD back in the days - this was just clicking, reading and doing as said :D

thank you very much for that ;)

There's one question I have, nearly nothing to do with this toolkit and definetely offtopic, but here it is: If I let the nexus 7 get the latest update, will I keep root?
[Nexus 7 Android Development] WugFresh:
http://www.wugfresh.com/nrt/faqs/can-i-still-take-an-ota-after-i-unlock-and-root-4/

OTAs break root unless you use an app like root keeper, or you enable "Survival Mode" in SuperSU's settings. That said, you can just reroot again with the toolkit if you need too.

I still got problems with getting into recovery mode...I unroot the device than root again with stock recovery and everythin goes just fine. When I try to get into recovery I got that android sign wit red exclamation mark again. Help!
[Nexus 7 Android Development] WugFresh:
That android on its back is stock recovery. You need to press both volume buttons and power button to see the menu. If you want a custom recovery then you need to check that checkbox before hitting the root button.

[Nexus 7 Android Development] tamanaco:
Is this restriction specific to the ROM images for Google Nexus devices?... I thought they could be modified. I should've qualified my question a little bit more. Maybe not a "complete" non wipe... just preserve the /sdcard /data folders. I have a back-to-stock ROM for my SGSIII with root injected, it does not increase the Samsung flash counter and it also preserves the /sdcard and /data folders.

Need a little help.

I had my N7 4.1.2 rooted and USB OTG worked fine.

I unrooted, updated to 4.2.1 and rerooted with the 1.6 toolkit.

Stickmount says that my usb is mounted but I cannot access it.

Several different file managers used and none show any usb data.
[Nexus 7 Android Development] Steph310:
Thanks!

I just bought Nexus7 and I had 2 updates with OTA up to 4.2.

After that I searched to root and I saw fortunately your Toolkit.

I used v1.6 and it worked perfectly!

Today update with OTA (4.2.1) done and logically losted root.

Update Toolkit v1.6.1 and new root that works perfectly!

Thanks for your work and your nice tool! :good:

[Nexus 7 Android Development] volarchico:
Before making the jump to 4.2.1, I decided to back up my apps this time - really didn't want to lose my Angry Birds: Star Wars progress :laugh: - since last time it got wiped clean. So I used the toolkit to backup the apps, followed the directions, and it created a backup to my computer.

I finished the update, re-rooted using the toolkit, and then restored my apps using the toolkit. The result? All my "free" apps were properly restored, but all my purchased apps were not! So I managed to keep my score in "Angry Birds", but lost everything in "Cut the Rope". :(

I have yet to successfully update my N7 without having to start over on all my settings, widgets, and apps. This time I got one step closer with all the "free" apps being restored completely. What did I do wrong? Is this by design that the purchased apps are not backed up?
[Nexus 7 Android Development] Rildiz:
7 minutes and counting.....still booting up after unlock...getting scared. Nexus 10..

Class Not Registered Errors

Wug, This relates to 1.6.1....

I guess you're aware of this already, but just in case it's been overlooked - The links to "Google's Factory Image Page" and "Goo.im Factory Image Page" on the "Which Factory Image?" screen both result in "Class not registered" errors.

You get the same error when trying to view anything from the "Help" menu apart from "About Nexus Toolkit".

Even the "Please Donate" link gives "Class not registered" :eek:

As an aside, having to go to 'Help' and 'about' does not seem logical to me to re-fresh the File Master List. Perhaps have it in a more open and logical place next time - Perhaps under 'Options'?. It'll save many threads later on ;)

Question

Does this root nexus 7 on 4.2.1?
[Nexus 7 Android Development] WugFresh:
I was not aware of that. All those links work for me on every computer I have tried. If you could hit me up on gchat I would like to troubleshoot why that is happening on your machine, and see if I should revise my code.

I agree about your aside comment. It is not ideal the way its set up now. It should also automatically notify the end user when its time to update the master lists if the user has the option to check for updates on each run. I need to do it with version numbers etc. Rather than your idea to put it in the options menu, I think I will just make a new menu item at the top next to Help, called "Updates..." or something.

I greatly appreciate your suggestions. I am trying my hardest to refine everything, but my personal opinion is not enough on its own. User feedback helps a lot. I try my hardest to imagine myself being the end-user, but its hard because I coded the whole thing... lol.

I will definitely revise that in the next release (v1.6.2). Cheers.

{{ WugFresh }}
[Nexus 7 Android Development] WugFresh:
Indeed. Note the picture in the OP. Also the toolkit will always support the latest build forever, via the in-built updater feature.

If you use "Help > About.." and update the master lists, then the toolkit will update to support the latest builds when they are out.. assuming I put the new masterlists up.

If a new build comes out and I have not yet updated the masterlists, notify me and I will, or use "Any Build" mode to root it, and wait for a master list update for full support for the other toolkit features.

{{ WugFresh }}
[Nexus 7 Android Development] WugFresh:
Yup. In fact you can flash any stock build you want, regardless of what you are currently running. Which makes that feature great for updating to the latest stock builds, in addition to just using it as a restore feature.
