Non rooted stock Nexus with Lollipop 5.0 on bootloop - Nexus 7 Q&A, Help & Troubleshooting

I've spent hours on this forum installing Nexus Root Toolkit, adb drivers, etc etc.
I just can't get past the fastboot command. The instructions all say that the device will reboot. But when it does it just goes into the bootloop again. The only option I've ever been given is 'adb sideload' but I can't find instructions on this issue.
Is my Nexus bricked? I've rooted and installed bootloaders on other phones etc but this seems to have stumped me. Any ideas?

Hi,
Questions go in the Q&A section, and development goes in the Development sections. Roms, kernels, mods... Etc.
Please post in the proper section. I've moved this to the Q&A section.
Thanks,

Rooting FRF85B

Hello,
Right now I have the stock FRF85B build on my nexus one. I want su and superuser, nothing else. I have already unlocked the bootloader. What do I do from here.?I do not want to install custom ROMs at this point.

That's great - but didn't you start with a custom recovery?
Can you drop a custom recovery on a stock recovery for FRF85B without the right Superboot?
I ask, because I am also stuck with this stock build and recovery. And when I read the instructions for installing Amon_RA, one of the prerequisites is Superboot. The problem is that there is no Superboot for this build yet.
HALP! I feel like I'm stuck in a chicken-and-egg scenario.
Ah I forgot that part. Wrote that up while at work. Inthe last section there is a link to the page where lox posts an update.zip for root access. I opened the zip and extracted the boot.img and flashed that I think,then I flashed the recovery for amon-ra.
After that is when I put the update.zip from lox on and flashed his update.zip for root access with the such utility.
The method posted in the dev section works perfectly. Root without unlocking. Then you can install a custom recovery/rom if you want.

I second this post. I am in the EXACT same situation as the original poster and I'm frankly embarrassed that I can't figure out what to do next.
If we're making huge requests, can you write it up for mac users? There is a surprising lack of documentation for us. I hope this doesn't open me up to a flamewar - if it counts for anything I've been lustily eying windows 7..
edit: I'm an idiot and had not googled the right question. If you run a mac, and have the bootloader unlocked already please see this link:
http://theonda.org/articles/2010/03...-performance-boost-and-some-serious-geek-cred
use your brains to suss out the relevant directions, make sure you have a more updated version of ROM Manager or RA or whatever custom recovery you want and basically just ignore the stuff about custom radios etc. You're basically just using the terminal (or whatever windows / linux does) to flash the custom firmware back on.
Again if you have the bootloader already unlocked (icon appears on startup), just find generic directions for your OS on how to install custom recovery. On the mac, it's simply few terminal commands using the fastboot program linked off the page linked above.
Sorry I can't be of more help - i have to be up early and it's pushing midnight.

[Q] Best method for root and custom recovery for Sprint Galaxy S4 mf9?

Hi,
First, I'd like to thank everyone (names unknown) for their time and effort in helping me root my first few cellphones. I've found many helpful posts over the years. Never had a problem.
Now, I have rooted my Sprint Galaxy S4 and installed a custom recovery MDC build. I then installed the OTA update to MF9 which knowingly destroyed root. I have tried several methods to install the custom recovery and root for MF9. When I run Root Checker, it tells me that it may take a little time because the system appears to be running slow. When I use Root Explorer, it won't let me change from r/o to r/w. To me, this means it isn't rooted.
What I am looking for is either a response explaining how to install a working custom recovery and root to my phone or a link to the best method.

Just use cf auto root in Odin, then use Odin to flash your recovery. The thread is in one of the dev sections. Can't link it just now but it should be easy to find.

First, I am by no means a Mod... but just as a little tip they will tell you questions belong in the question section and move it there where it will get buried. You better off posting future questions there where people often help if they can.
Ok onto your thread.
If you check out these two sections in the thread you linked they should help you. You will want to do the Custom Recovery Flash first then install Chainfire's SuperSU
CUSTOM RECOVERY FLASH
Recovery TWRP. Download this.
DL LINK http://techerrata.com/file/twrp2/jfl...0-jfltespr.tar
About TWRP http://www.teamw.in/project/twrp2
With USB cable NOT connected, turn off your device. Now boot into download mode. (Hold volume down then power...HOLD and WAIT... then volume up to accept message) Now connect USB cable.
Put the TWRP recovery .tar in the same folder on your computer that the Odin execution app is. Right click Odin.exe and click run as administrator. Flash TWRP using PDA mode with auto reboot UNCHECKED. Hit start. When you see RESET or PASS, move on.
Unplug USB cable. Next hold down VOL UP and the POWER button until the device turns off. Keep pressing VOL UP and let go of POWER. When you see the blue "recovery booting" let go of VOL UP. You will then boot into your new recovery. This should work if done correctly. Resore your Data back up if necessary and reboot. It SHOULD realize you are not Rooted and ask you if you want to Root. Select to Root (or not) and your done!
HOW TO ROOT STOCK MF9
You can either Odin flash CFAutoRoot from here:
http://forum.xda-developers.com/show....php?t=2291827
Check here for How To video:
http://forum.xda-developers.com/show....php?t=2257101
OR Custom Recovery Flash UPDATE-SuperSU-v1.41.zip from here:
http://forum.xda-developers.com/show....php?t=1538053
Flash UPDATE-SuperSU-v1.41.zip in TWRP or CWM to gain the latest and greatest Root for your S4 from Chainfire!
You should now be rooted with MF9 for the Software version, Baseband version (modem) and Build number.
I am not an expert by any means but I have been through all of this after having my new GS4 for about a week. I, however, updated to MF9 first before doing any rooting or installing any recoveries so I don't know if that would make a difference or not. I first installed Odin 1.85 then downloaded the correct CF Auto Root tar.md5 file and installed that with Odin. It took seconds and worked perfectly. After that I installed Philz Touch CWM-based recovery also with Odin and everything seems to be working like a charm. See below

This is the easiest method to root I have ever seen.

Thank you everyone for your help.
I am finally rooted.
I went back to an older stock rom. Then I followed the link in my original post.
Everything went smoothly.
But, Triangle Away doesn't work anymore.
I get the following message:
Could not locate hidden partition or could not detect device model. Are you running Android 4.0 or newer, and are you rooted, and is your device supported?
I uninstalled and reinstalled Triangle Away. Opened it again and got the same message.
I'll search the forums to see if there's an answer.
But once again, thank you for your help and encouragement. Just wish that I had more time to tinker with custom roms!
Additionally, I didn't lose any data throughout the whole process.

[Q] What rom for my needs?

Hello, soon i'm gonna receive a nexus 7 first gen, and I've been wondering... Can someone please point me to the guides to rom/custom recovery/kernel etc install? I'm an ex galaxy y rom dev, so I'm not clueless,but I was overwhelmed by the amount of work and wanted to see if someone could guide me through the process of bettering my future nexus.
What I'm looking for: overclock, paranoid possibly but cyanogenmod is fine too, being able to play long sessions of ingress over tethering.
Stock.
So you're saying you're an ex-dev yet need someone to guide you? Look in the stickies, there's plenty of guides already out. No reason for anyone to write up a new one about stuff that's already covered in detail.

Best advice you'll get is to do a nandroid backup after you install custom recovery and root.....then read the different rom features and flash and flash....til you find something you like. Its all preference .....10 people will respond to this with 10 different suggestions. Its really not gonna be helpful to you.

Hi, sireangelus...
The moderators here on XDA generally frown on 'best ROM/best Kernel' type threads and posts, so I'm not going to recommend any. Besides, it wouldn't be of much use to you anyway... ROMs and Kernels are very much a matter of subjective taste. Checkout this thread, where such discussions are allowed.
------------------------------------------
With regard to flashing anything on the Nexus 7... the first thing you need to do is get your Windows Drivers sorted out (I'm assuming you're using Windows; apologies if not - sorry, but I have no experience of Linux or Apple devices) .
Read this thread on driver installation... actually this thread is worth reading in its own right, as it contains a lot of very useful and pertinent information with regard to the use of fastboot.
------------------------------------------
Custom ROMs come in .Zip form and are flashed via a Custom Recovery, like TWRP or CWM. Once you have either of these recoveries installed you can Root, flash Custom ROMS and/or Custom Kernels.
Although there seems a lot of material to read through, opening up your Nexus 7 to Custom ROMs isn't quite as difficult or as technically challenging as it appears. Your primary goal should be to get a Custom Recovery installed first. A short synopsis is as follows...
*****
1. Get your PC drivers installed and working, so your Nexus 7 can 'talk' to your PC.
2. Hook up your Nexus 7 to your PC, boot into the bootloader, and UNLOCK the bootloader.
3. Fastboot flash a Custom Recovery, like TWRP or CWM.
4. Using that Recovery... flash the Custom ROM .Zip of your choice.
*****
You will need to know how to use fastboot. It's a powefull command line tool, and the two most important commands are...
fastboot oem unlock - used for UNLOCKING the bootloader. The Nexus 7 bootloader MUST be unlocked, before fastboot flash commands can be executed. Even if you're just returning the Nexus 7 back to factory stock, the bootloader MUST be unlocked.
fastboot flash recovery recovery.img - used for installing a Custom Recovery like TWRP or CWM, where recovery.img is the name of your Custom Recovery .img file.
For myself, I just rename Custom Recovery .img file anyway, to recovery.img, as it reduces the scope for typos at the command prompt, and it's easier to remember and type than something like openrecovery-twrp-2.6.3.0-grouper.img (for example)... which is the full name of the TWRP Custom Recovery .img file for 'grouper' Nexus 7's.
------------------------------------------
Short of 're-inventing the wheel'... and rewriting what has already been written, read the stickies at the top of this forum.
Take your time... understand what you're doing (and why you're doing it), and it's difficult to go wrong.
Good luck.
Rgrds,
Ged.

Thank you fir the advice, ill treasure it. I didn't exactly asked for the best rom, didn't i. What i intended was to narrow it down a little bit. For example, do kernels here work both for stock and for paranoid/cyanogen?

[Q] Want to unlock and root but use with stock rom

Is it possible to unlock bootloader, root, flash twrp and somehow flash the stock rom? If yes, where can I get the rom files for flashing with twrp?
thanks
You're already stock. You don't have to flash stock images again. Do yourself a favor and read Heisenberg's unlock/root/flash guide in the general section. Its stickied. Had everything you need to know about this device.
I've read the post already. The problem is that when unlocking the bootloader the phone is hard reseted. So after unlocking, rooting and installing twrp I would need to flash the stock rom. I just want to have root, but with stock rom.

After unlocking it erases your user data. The system image is still there it would be as if you turned it on for the first time. You do not need to reflash stock after unlocking, rooting and installing twrp.
Good news then! Thanks!
Just follow that guide exactly as it states and you'll be golden
The folks above are correct. That's exactly what I did. I'm unlocked, rooted and running the stock rom. You can also install kernels on the stock rom w/o having to reinstall anything.
@jejb What will you do when Google launches another update and you want to have it?
That's a good question. And it seems they roll out these little updates monthly. So far, I'm just ignoring them. I wish I could find a way to remove the notification. But I'll wait until there is a meaningful update to go through the process of un-rooting. That process is in the pinned thread, too. If you can live with the systemless root, it's a lot easier to take the updates.
@joooe, your question is covered in the above mentioned guide. Look at section 10. Before doing anything to your phone, I strongly suggest reading guide in its entirety.

twrp

Hey guys can i use this twrp
With stock miui and magisk root will it boot loop and boot to fastboot or will go smooth
How about you request to delete this and then post your question in the right section?
