New Nexus 7 User needing Unlocking/Root advice

Hey XDA
Iv had my Nexus 7 for a day now and am dying to root and mabe install CM10
i currently have a Samsung Galaxy S3 with CM10 on it...thot its extremly buggy sadly... anyways i have been looking up on how to root the nexus 7 but i need to know if i can instead of using toolkit can i instead just use odin to flash stock rom and cwm and so on instead of having to unlock the device?
i am used to using odin for flashing and cwm but here the nexus is close to the same with htc one x in the way it has that fastboot thing and from what iv heard the nexus 7 requires unlock before it can be rooted, also is the tookit the best way to unlock and root the device?
also does unlocking break the warrenty and if i ever decide to return to stock unroot how do i flash stock rom back onto the device? am not sure where i would find the stock roms for it and also can odin be used to flash it...:S
i hate sounding like a noob lol

ok iv used the toolkit 2.0 and its worked great so far...im stuck at not being able to boot into cwm recovery
it installed fine thru the toolkit but whenever i try to hold up and power i cant get it to boot into cwm recovery...
i tryed to reinstall again but still cant get it to boot into cwm am i doing something wrong?

Doing the following won't cause you to loose warranty:
- Unlocking the bootloader
- Rooting
- Flashing custom ROM's and Kernels (however, if you flash a custom kernel that causes your device to explode... I'm somewhat certain this won't be covered)
However, if you are doing anything like that, and have to send the device in for warranty, you "should" factory restore it. Google provides Factory Images for the Nexus 7, which can be restored to your device with semi-ease.
I use this guide to factory restore: http://forums.androidcentral.com/ne...ide-factory-image-restore-your-nexus-7-a.html Some filenames might need changed though since I think that guide is based off an older factory image (instructions are the same though).
There is a good chance a toolkit also has an easy method for factory restoring, but I don't recommend this at all.

Stop using toolkits.

I've never used a toolkit before (until this issue had me stuck). I'm unable to get the Nexus 7 to book into recovery (CWM) after flashing it via fastboot. After giving up, I rooted it using the toolkit.. scariest thing I've ever done.. it did work.. but I'd like to get to the bottom of why a number of people like me seem to be having issues flashing and booting CWM on the Nexus 7.

Did you rename the original system/recovery to .bak first?

No, I flashed it as I normally do.. using the .img file. In this case, CWM.. recovery-clockwork-6.0.1.0-grouper.img
Why would renaming it to .bak be needed?

I had to rename the stock recovery under system to .bak before I could get twrp to work. Or else when I went into recovery it would get stuck on the android.
But I see you are using fast boot it should write over it.

I didn't have to. Flashed twrp and forgot to put a ROM on it and went back into recovery and it was twrp still.

I should of just flashed the image file and flashed it myself but I was in a hurry and used goo im and it bit me in the ass. Lesson learned.

Recovery won't flash

I had to do a complete wipe from the computer and flashed clockwork mod recovery. Since it was likely an old version I had the double 0 partition problem which I fixed by manually moving the files. I tried to update the recovery to twrp, but it won't flash using goomanager. It downloads and says it's flashed but it's not there.
I also seem to have a weird problem where I have to push the power button to get it to boot past the Google screen. If I don't push power it gets stuck there forever.
Any ideas?

Follow the sticky at the top that says flashing a factory ROM using fastboot/return to stock. Start from scratch, get it working, and then flash whatever you want.
Sent from my Nexus 7(2012) that has zero issues.

That's what I did, that's why I'm stuck on the old recovery.

This might be an odd question, but have you tried just updating CWM first, and THEN flashing TWRP? Sometimes the flash won't go smoothly with an older version of one recovery to a newer version of a different recovery- not sure why, but that's just been my experience. I would update CWM first then try flashing TWRP.
Also, if goo is not working for you, you could try Rom Manager to update CWM and then flash TWRP. It can flash either. (If you really want to flash via the device).
Otherwise, (me personally) I'd just use adb fastboot to flash a new recovery.
Hope that helps

Thanks I will try that.

No problem. Let us know how it works out for you.

Tried flashing with fastboot, now it won't boot into recovery, just hangs at the Google logo.
Still needs a bump from the power button to get it to boot normally.

Ahh, that sucks! How are you *attempting to* access recovery... via reboot menu, via adb, or via 3-button press? It shouldn't matter, but you could try all three methods to see if any way will give you recovery access. Then, if/when you manage to get in, you could reflash again straight from recovery. I'm going to do some digging to see if I can find a better solution. I KNOW I've read about the same issue before, I know there's a solution... I just have to find it again.
Worse comes to worse, you might have to reflash stock recovery then reflash custom recovery. Might be a corrupt recovery img, but I will check and try some things out and let you know what I find.
Edited to add:
Yes. there was a bug in the older bootloader that bypassed/refused access to recovery... so since you restored stock, you probably need to update your bootloader to at least to version 4.18 (via fastboot). THEN you should be able to access recovery. I can't add links, but I can give you a text link once I find just the IMG file instead of the full firmware. Honestly, I never do backups so I don't have the file on hand. However, I may do one backup at least so I can extract my boot img and give it to you.

OK, so I found the info I was looking for.
From Elsewhere:
Steps:
Install latest nexus 7 bootloader.
This fixes the boot loader bug and now you can enter recovery from the bootloader screen.
Update the bootloader to at least 3.18. Make sure NOT TO DELETE THE BOOTLOADER!!!!!!!!!!!!!
I cannot emphasize this enough!!!!!!!!!!! I bricked my first one this way.
Use
fastboot flash bootloader C:\>>>>>>\bootloader-grouper-3.18.IMG***

Do NOT erase bootloader before you flash the new one. And after you have flashed the new one type;
fastboot reboot bootloader

and check the bootloader version to make sure you succeeded.

***Or whatever you name the boot img file!***
https://dl.dropboxusercontent.com/u/19608328/boot.img.zip --> This is from MY Nexus 7. It's Bootloader version 4.23, and works with JB 4.2.2- it does NOT have the recovery access bug.
https://dl.dropboxusercontent.com/u/19608328/recovery.img.zip --> This is a copy of MY CWM, which I just updated to 6.0.3.6 yesterday.
I'd flash the bootloader, then flash your recovery of choice. Not being able to access recovery is a bootloader issue, not a recovery issue. The fact that you restored/reverted an older full firmware put you on an older bootloader that would not allow users to access recovery.
Try the new(er) bootloader, it should work. My device is a 16gb grouper Nexus 7 running 4.2.2. Before that, it ran 4.1.2 without any issues, so it should work to resolve the problem you're having.

Flash issues

I'm on twrp 2.6.3.0 and anytime I try and flash a new 4.4 ROM the install fails.

wrong advice, my mistake... thanks for the reminding simms22.

But I wanna stay rooted
Sent from my Nexus 4 using xda app-developers app

You don't have to unroot. Just download and flash TWRP 2.6.3.2. On that build, they fixed the issues of 4.4 ROMS incorrectly flashing. Using it myself with no problems. Its in Original Android Development if I'm not mistaken

Flashing 4.4 Factory Image issues
Currently on my Nexus 4.
Android 4.3 Unlocked and Rooted
Kernel Version: 3.4.0-perf-gf43c3d9
Build: JWR66Y
Baseband: M9614A-CEFWMAZM-2.0.1700.84
Using ClockWorkMod Recovery v6.0.4.3, when trying to flash the 4.4 factory image .zip file on the SD Card I keep getting an "Installation Aborted" error after "Installing update..." step and the red Triangle on the android figure.
When attempting to sideload using stock recovery, getting a "Signature Verification Failed"
Any Suggestions? Thanks

If you haven't already tried it, under Mount uncheck system, that solved the problem for me.

op, all you have to do is update your recovery to twrp latest(v.2.6.3.3). flash your rom, flash your 4.4 gapps, and flash the latest supersu then reboot.

I will chime in on this one. I too have had constant failures with TWRP trying to flash ROMs lately. I'm running 2.6.3.3 and everything results in failure. I've tried the unchecking of system mount, multiple downloads with verified MD5s, sideloads, etc. Nothing is working.

next time you flash, after it fails, boot into the bootloader from the recovery. then, from the bootloader, go into the recovery again and flash.

ill be honest, i dont know why. but i do know that it has worked for many. the alternative, which works 100% of the time, would be to delete your recovery, then flash it again. btw, did it work for you?

I won't be able to experiment for a couple of weeks. I do know that I've wiped my phone four times or more in the last week with the 4.3 and 4.4 factory images and either manually or using one of the tool kits have added TWRP custom recovery and rooted the phone. Each time trying to flash a ROM it would result in a failure.
Next time I get the chance, I'll give your suggestion a shot and let you know. Are there logs I can capture that might prove useful?

So essentially I've done that with each factory image installed, correct? I'll have to read up on ADB and Fastboot to get the commands to remove the existing recovery. Will be a good way to kill some time (such the life I lead, being envious is not good for your soul)...

no, you just flashed the next version of the recovery over the last. occasionally, something doesnt want to update in the partition, so clearing the previous recovery before flashing the new one will take car of it.

OK that confuses me. If using fastboot to place a new boot loader, radio, recovery and ROM are onto the phone and I have to 'fastboot flash recovery recovery.img' to replace the stock recovery that doesn't wipe out the stock recovery? Fabulous sentence structure.

That's a contradiction. Need to flash stock everything, even the recovery. Once you do that, and the phone is running correctly, then you basically start over again.

In NRT :
Advanced utilities : Launch
In Advanced utilities :
Boot / Flash Image
Boot (Temporary)
choose openrecovery-twrp-2.7.1.0-mako.img in C:\Program Files (x86)\WugFresh Development\data\Recovery_Custom\TWRP
You will be in TWRP

You need to flash the factory images with fastboot, not a custom recovery. See this, http://forum.xda-developers.com/showthread.php?p=34552123. Also, use twrp not cwm.
