custom kernel, what to know? - Nexus 7 Q&A, Help & Troubleshooting

Surprisingly I can not find this answer anywhere?
So I'm considering using a custom kernel called Timor kernel. So that I can use an OTG cable and charge my nexus 7. What I need to know is what do I loose? Can I still update from google? Does this oversight the bug fixes google made since 2013?

You can still update from Google but you'd have to flash back to stock completely. Or you can flash the many flashable stock ZIPs that pop up within the first few days.

You mean if I follow the thread I can just grab the "new release's" and if there was a google update it should be included?
Oh also, will this force me to reinstall apps and do all the google authentication as-well?
hmm, just saw this?
"If you are NOT currently running CM 10.1 or USB ROM, you need to first do a factory reset (wipe data partition). This will remove all your apps and custom settings. "
So that is a yes then?

Usbrom never made it past 4.2.2 (cm 10.1). You can always update the apps, but not the core os, eg.. 4.3, 4.3.1....... I run usbrom in multirom, so I have it for when needed, and 4.4 roms when I dont.

This doesn't even matter, all the devs have the official ota update before it comes out due to Google dropping the source before they actually push it out.
Way better to root, you'll have the updates faster that way.

IF you do only one thing, unlock the bootloader before getting lived in on the device. I am rocking stock rooted myself. I am just watching till after cm10.1 hits stable then Ill try some roms out
While I personally prefer stock (with modifications of course) on my N7, it is trivial to revert these devices back to stock, or any other ROM, if you want to. You don't even need to revert and upgrade - you could just download the latest FULL image and flash your device that way, skipping the update step altogether.
But if updates are your only concern, I imagine most of the ROM developers would incorporate the new version into their ROMs very soon after the OTA drops.

This.
Even if you don't run a custom rom initially, if the bootloader is unlocked, you can easily flash a custom recovery and rom later. The problem is that if you unlock all the internal storage gets wiped which is not the end of the world if you backup first but it's still a minor inconvenience.

paranoid is great, but depends what you like. I love it fit the tablet interface and customization options. stock 4.2 had a lot of the same customization built in, so it's awesome as well.

To me, its custom ROM or bust.

Multi ROM
you may want to use Multi ROM.
Root your stock ROM.
Install Custom Recovery to install Multi ROM.
After installing Multi ROM, you may now install other or more ROMs inside.
Also, you have the option to auto-boot from stock ROM or from other ROM.
With that, you may access your stock ROM without removing your custom ROMs and vice versa.
Goodluck!
I unlocked and rooted my nexus 7 so that I could use otg cable---> a flash drive … I have extra storage now. Just download an app called stick mount an your all set...
Rooting should be the first thing you should do. As others said you can keep it stock if you want. Only difference is you get to install apps like titanium backup and file managers like root explorer. You also will have a custom recovery so you can backup your latest STABLE and smooth ROM so you can revert back if you ever run into trouble like the 4.2 OTA debacle.
As far as any maintenance and fixing issues... having root makes it a breeze as factory resets just mean in 10 minutes you are back in businesses, you just need redo your screens.
I took the plunge and after rooting I installed this: [EXPERIMENTAL] MultiROM v3
Now I'm running stock along with a few other ROMS, including Ubuntu.

Custom ROM/recovery/... vs Stock

Hey there, I have been flashing my HTC Desire HD for a long time with different ROMs. I found it kinda annoying to always check certain websites for new updates, manually download and flash them just to find out that half of the stuff was buggy.
Now I got the Nexus 4. I loved the idea of having fast OTA updates. But now I want to flash a new kernel.. which means I got to install a custom recovery. But then OTA will not work anymore.
So I wonder:
Should I stay with
CWM + Stock ROM + Custom Kernel (no OTA update but no problem with buggy custom ROMs)
CWM + Custom ROM + Custom Kernel
Everything stock
Cyanogenmod is nice but for me it doesn't have any big advantages over stock 4.2 ? So I really wonder what you guys would recommend? What are your reasons to do a "certain setup" ?
Thanks
You don't need a custom recovery to flash a kernel.
It can be flashed with fastboot leaving everything else stock.
You still wouldn't be able to install the OTA without flashing the stock kernel again though.
Oh crap.. so as soon as I change ANYTHING... no OTA updates anymore
Hmm... I guess I will stay with custom kernel + flashing stock ROM then :/ Is there any way to automatically check for updates tho?
Thanks

Yeah you will get the notification and it will try to install but it will fail and reboot if you aren't 100% stock.

Go with TWRP instead of cwm

+1, TWRP is great :highfive:
TWRP is the way to go!
But then I have another problem (well I already have it but..):
I would like to use ROMmanager.. after all it might be able to check for rom updates & flash them "automatically" (stock + custom?). I am not sure if it could also check for kernel updates?
Anyway, it seems to work only with CWM ? Altough it doesn't seem the already installed CWM on my Nexus 4 :S
Anyone?
I would never use ROM manager. Not a good program. Use a custom recovery, and if you want lots of customisation then I would recommend AOKP Rom as it is just as fast and stable as the stock ROM but with a whole host of customisation options.
Beauty of this phone is that you can go back to complete bone stock with no issues, I did, but missed all the customisation and put AOKP back on lol.
alright I uninstalled it. I just hoped for some "app" which could look for all kind of "custom" updates and install them automatically (kernerl,rom,...)
If you're interested in CM, I think delta CM will allow you download only the changes made to the project.
Also, why do people say to use TWRP instead of the more tried and true CWM? It seems to have a lot of sex appeal to some recently, and there doesn't seem to be a clear cut answer. Is there added functionality?

Updating CM10.1 on Grouper

Hi guys,
I'd like you to help enlighten me on this subject. I remember reading somewhere that if you're already running CM10.1 on a device, you can simply flash the updates right on top of it, disregarding a data wipe or cache wipe. I'm running the M1 build (CM10.1) for grouper (Nexus 7 WIFI), and would like to update to the latest nightly (Jelly Bean 4.2.2) because my OTA update failed when I was on the stock ROM.
Is this true, and does it work for other ROMs as well? In other words, if I take another Jelly Bean ROM (say version 1.0.1), and update to the next latest version (1.0.2), does this same process apply, where I can just flash the updates over the top and be done?
Thank you!
??? Cm10.1 comes with a self updater. It looks after cache and app compatibility for you. None of the other ROMs have it. Its one of the many reasons why I like cm so much. I update it once a week. Its like a dirty flash without the extra work. Look in About Tablet for it.

I don't mean wirelessly. I mean actually downloading the files, and flashing through recovery. I don't have a stable WIFI connection from my Nexus 7, so I have to use direct download. I have a pretty fast network, though, plus a download accelerator, so I get the .zips in like 15 seconds.
Again, I want to know if I can flash any update of CM10.1 on my Nexus 7 and be fine. I'm running the M1 experimental release for grouper. I heard about people saying you can just flash the updates without clearing cache or anything like that. Just flash and you're done.

[Q] Nexus 4 Update

Hello, I will get a Nexus 4 now in early May, but I came up with a question about updates. If i leave the phone with the stock rom, I'll lose my apps and settings to replace the future stock Android 5.0? And if you install the Latest build of Cm 10.1 when developed the custom rom Android 5.0, i will need to wipe and lose all? Thanks ;D (Sry for my bad english)
No if you update your phone from stock 4.2.2 to 5.0 you'll lose nothing. Everything stays as it is.
Yes, if you install any custom rom over a stock rom, you'll wipe and lose all. But all of your applications will be downloaded automatically from your gmail account and for like launcher settings or kernel settings you can backup all the info or you can use titanium backup app in order to backup everything.
So there is nothing to worry about.
Edit: By the way i am not really sure about the thing about going from 4.2.2 to 5.0. For minor updates like from 4.2.1 to 4.2.2 you lose nothing. But i don't really sure about 4.2.2 to 5.0.
Hmm i take that, but anyone can tell me if i install the Cyanogenmod 10.1 (4.2.1) When come the Cyanogenmod 5.0 (Assumption), the team of cyanogen make this update with no wipe necessary?

If it is a big update with many changes a full wipe must be done in order to get it working correctly. You can always easily restore user apps with Titanium Backup or adb.

It's recommended to do a full wipe to avoid problems if you're going to install a new rom. The developers will most likely have to wait a couple of weeks or so for Google to release the files for KLP for them to access and use. No rush. No rush. :good::laugh:

[Q] Is Stock 4.4.2 relatively safe and stable for Nexus 4?

I am among the last crew of US customers for the Nexus 4. Having seen lots of KitKat bug reports, I have been deliberately keeping my Nexus 4 at Android 4.2.2. (My phone is rooted but I have retained the stock ROM and I prefer to stick with stock versions for now.)
For those of you already using stock KitKat 4.4.2: Is your experience smooth? Has battery usage been consistent/better compared with previous Android versions? Would you recommend that I update? Or should I wait a bit longer?
(I also wonder how many interim updates I'll have to do if I go through the official OTA process.)
Back up your rom / apps / data etc to a computer.
Flash the stock factory images to your phone and see if it works for you.
Or you could of course just back up your rom and flash the factory images without the - w line from the script to keep it from wiping your internal storage.
Bottom line is back up your current setup properly. And flash the new rom. Don't like it revert to the backup.
Don't like your backup. You could refresh the factory images for your current rom. They are still right up on Google factory image site.....
I've been using the nexus 5 ports since day one and I've never regretted it.
4.4.2 for me is just overall more fluid, more battery friendly. If you don't need the xposed framework you can even enable ART for an extra performance/battery boost.
