Rooted N7 - best way to update to 4.3 ROM? - Nexus 7 Q&A, Help & Troubleshooting

I rooted my N7 (NE370T) a few months ago but can't remember how I did it. I would now like to flash a stock 4.3 ROM to it, and was looking for the safest way of doing it while retaining root. I have CWM 6.0.1.9 installed - would it be easiest to install a flashable stock rooted ROM zip from CWM? (e.g. http://forum.xda-developers.com/showthread.php?t=2376881)
I'm currently on v4.2.1 (JOP40D)

Yes it would be easiest to flash a 4.3 ROM actually. I went the way of Clean ROM 4.0 and faux kernel and I don't regret it. It came pre rooted and optimized. Though as always you should make a nandroid before you flash anything.
Also, make sure your bootloader is up to date if you have problems flashing a 4. 3 ROM

Sorry for the dumb question, but how do I check and update my bootloader version??

Check the dev section for the latest bootloader. As for checking, you'd have to use commands in fastboot and I'm sorry I don't know them. Basically what I would do is just do as I said in the previous post. If things don't work, then it's obvious you'd need to either update Cwm or your bootloader or both.

You might want to have a look at my blog, there I described a very easy way for updating to 4.3

Boot loader version comes up in the bootloader screen ( vol down + vol up + power while tab is off ) .. And to flash the bootloader
Code:
fastboot flash bootloader bootloader.img
4.23 is the latest version for bootloader.

Thanks for all the help. I managed to successfully flash a pre-rooted 4.3 stock ROM from a zip using CWM recovery. I suspect that my bootloader may not be the latest but everything seems to be working OK so I guess it's OK to leave it.

[Q] Unlock Bootloader Android 4.2.2

Hey Guys,
i downloaded the nexus 4 toolkit. the latest build (4.2.2) isn´t shown there.
i dunno which version is included in the stock n4. i will get it in a few hours and i just wanted to ask, if my plan is gonna work xD
1. update to the latest version
2. unlock bootloader
3. customrecovery
4. flash rom
the only problem i am facing now, is that i don´t know if the toolkit can unlock the latest bootloader, because "JDQ39" isn´t shown as listed device. or should i unlock the bootloader on a previous version, the stock delivered (i don´t think it will come with 4.2.2) and then install the stock image? as i know from my galaxy nexus the bootloader will be unlocked after that. but i´m not sure how it is with the nexus4.
i hope someone can help me. it might be a noobquestion. i just want to make sure that everything works fast, because this nexus4 is a present for my sister and she´s waiting for it

Normaly it should work, allthough it is not the exact firmware the procedure stays the same. So you should be good.
But between item 3 and 4 comes flashing the superSU zip with CWM/TWRP from here http://download.chainfire.eu/315/SuperSU/UPDATE-SuperSU-v1.25.zip. After reboot you also have to install Busybox from Google play, after that make a nandroid backup in recovery and then flash the rom.
mmh don´t need root in my case, if the recovery will be installed by toolkit, root will be included in the rom anyways

Root is not achieved by flashing a ROM.

It can indeed be achieved that way. If you have an unlocked bootloader and custom recovery then you still might not have root, but you could just flash a pre-rooted custom ROM.

Don't use the toolkit, it's easy to do manually. That way you will learn more about the steps involved, which will come in very handy if you have a problem with the phone in the future.

How to update android version when on a custom ROM?

So I am using CM10.1 with CWM recovery. What will I have to do when a new version of Android comes out? (4.2.3 or 5.0)
And will I lose my root access?

Either flash a new ROM that's built on the new version, or go back to stock.

And to flash that ROM, do you have to get new bootloader and baseband or what?
And go back to stock: do you mean to flash the factory image, or can you also get OTA updates by restoring a nandroid backup of the stock rom?
once you are rooted, unlocked and with custom recovery changing ROMs is as simple as puting zip onto your devices' internal storage and flashing it through recovery. you COULD be asked to flash a newer radio version, however it is not that common.
no OTA when rooted, going back to stock only with facotry images.
anyway 5.0 will be availabale on custom ROMs shortly after or even before official google OTA so no need to unroot.

So when 5.0 comes out, I just have to wait a day and flash a new CM version without flashing a new bootloader or radio?
And will it directly be stable?

Android 5.0 is far away by now, and nobody can tell you yet about stability
i´m sure it will get announced, just check the CM thread and read about (possible) bugs

As long as you read threads properly you'll know whether or not anything extra needs to be flashed. Even if there is something you need to flash in the future, it should be fairly easy. Normally a flashable .zip is released soon after the official release so you won't even need a PC. Personally I think it's useless to worry about it right now.

Radios and boot loaders are completely separate from ROMs. You have to specifically flash a radio or boot loader separately. But no, you should not need to flash them but it would be worthwhile if a newer version came out

I am a bit scared of flashing bootloader and baseband, because I read someone who flashed a wrong one and his phone completely got bricked. Some other guy said in that thread why would you manually flash a bootloader..

If I restore my Nandroid backup of 4.2.2 stock ROM, am I able to get OTA update? (I dont care if I would lose root, the question is if its possible ) or is it impossible since I am running CWM recovery?

If you are going to flash custom ROM; use a toolkit to Root it; flash custom recovery of your choice. Then copy custom ROM to ur phone; go to recovery and flash it. You don't need to downgrade your boot loader.

Does this mean we can downgrade from 4.3 to 4.2.2 custom ROM?
I'm not having a good time with 4.3 stock rooted and custom kernel and thinking about going back to CM 10.1.2. All I need to do is flashing the custom ROM in recovery?

Yes you will be fine. Before PA 4.3 rom was released, I was using Latest 4.3 bootloader with 4.2.2. I am going to revert to 4.2 as well. I noticed 4.3 battery is really good but sometime touchscreen doesnt response / volume buttons doesnt work.

for unresponsive screen go to 'developer options', 'hardware accelerated options', 'disable HW overlays' and select 'always use gpu for screen compositing'. Works for me but setting doesn't seem to stick on reboots.
^^ oh okay thanks but I am already back to the good old 4.2.2 .

Hi I´m quite new to this and did recently flash my second custom rom. I went from CM10.1 (4.2.2) back to stock image, and flashed
[AOSP]Official 4.3- S4 Google Edition- Finaly v2.0 - Feel the Experience of Nexus. The phone is running hot and I´m kind of dissapointed with the
lack of tweaks in Google Edition. So I´d like to go back to CM
So if I understand you right I can from 4.3 flash my stock image (from TWRP) which was on 4.2.2? Without worrying.
Did you make a nandroid backup when you were stock? That should be the easiest way to get back to stock. If you didn't then you will need to use odin to flash back to stock.

[Q] Unroot without full wiping

I recently realized that I use no root requiring apps or custom ROMs on my Nexus 7(while I keep my phone rooted for many a reason). Now that I hear the 4.4 update is being pushed, it occurs to me that all keeping a custom recovery and root on my tablet does is complicate updates. So I want to unroot, return my recovery to the stock, and get myself all ready to wait for the update to push out. What would be the best way to do this that does not require me to lose data/game saves/have to reset everything up?
Fastboot flash the stock recovery and don't worry about su because the ota will take care of that.

I am sure this has been answered somewhere and I did search the forum before posting but right now i am pretty excited about 4.4 and would like the experts to answer this regarding grouper :-
I got the 4.3 update OTA on a rooted 4.2. I later rooted the 4.3 but did not remove any default apps. I also have frano kernel installed and TWRP recovery. Does the kernel and custom recovery affect the OTA process? Am i safe for 4.4 OTA? or shall i unroot, install stock kernel and also stock recovery?
Thanks
You should be fine if you install the stock recovery before the OTA arrives

Open the SuperSU app on your device.. Go to the app settings and select the option to unroot/clean up.. Reboot. That is all.

Yes, you'll want the stock kernel and stock recovery installed.
On grouper, it can update independent of changes you have made to the system and recovery. This isn't true for all other nexus devices, for example, mako. Doing the 4.4 update will get rid of root for you, but it will flash fine even if you have a custom recovery. You may need to flash stock recovery manually if you don't want custom recovery anymore.

In the past, that has failed for me. I'm still one update behind on 4.3 because it would not install and I was too lazy previously to unroot and get it to install.

Root after manual update?

So I finally found some time for my unlocked and rooted nexus 4. Right now it is on 4.3 stock and I want to update to 4.4.2. Now the question which I couldn't find an answer on Google: Do I loose root after manual update? I've seen some videos on that, but some say that you need stock recovery (I have TWRP), but nothing about root.
Also, I'd install Franco kernel after that.
Help and possible tutorial would be appreciated, I'm still kinda new to android.
You can have a stock experience by installing the Experience ROM in the development thread.
Make sure you are running the latest TWRP before trying to flash a 4.4 ROM.

Yes, always when you flash another stock Rom, you will lose root.
But it's a matter of seconds to reroot after flashing latest supersu.zip through TWRP.
