[Q] a few simple questions - Nexus 7 (2013) Q&A

1) does flashing a custom recovery on the nexus prevent OTA updates from google. I know it did for my HTC sensation XE, but nexus devices are designed for unlocking & stuff
2) if it does prevent OTA, can anyone link me to the latest & best custom recovery anyway. I know i can simply use the "fastboot boot <recoveryimagefilename>" command to boot into custom recovery without flashing it
3) if i were to flash it anyway, can i manually flash OTA's then. According to http://forum.xda-developers.com/showthread.php?t=2380113 you need stock recovery to flash OTA's, then what's the point of custom recovery (other than nandroid backups) if ya can't flash stock OTA's

1) yes
2) I would use this http://www.wugfresh.com makes every thing easy as pie. I would recommend twrp (team win recovery project) wugs fresh will automatically download, and install the latest version for you
3) no you can't flash "factory images" but if you want you can run flash-all.bat with the SDK tools thru ADB, but that would replace your recovery with the sock one, and return you tablet to pure stock, with whatever android version you downloaded from Google. But the good folks here on xda will create an update .zip you can flash thru your custom recovery, before the ota is even available. As far as why have a custom recovery in the first place, you can flash custom software (ROM's, kernels, mods) that will have more features than all the ota's will have in 1000 years. :victory: Examples, Multi window, overclocking, undervolting, change the color of everything (lol everything) shortcuts every where, (EVERYWHERE, without getting in the way, I know, how, but they do it, lol) battery meter mods, themes,(change the whole GUI), expanded desktop, native screen recording, the list goes on on and on...
Anyway, no don't accept an ota while your running a custom recovery, it will probably soft brick you, but the features you will gain from custom ROM's/ kernel's will vastly outweigh the features you will ever receive from an ota (and almost all custom ROM's will be based off of the latest android version anyway, so all the latest android features will be baked in) so ya IMO you should go for it. :highfive:

your 2) does not answer the question. Im not asking how to root, i've already done that
3) is wrong again. After removing a pinyin keyboard on 4.3 the 4.4 OTA wouldn't work. so YES i COULD flash a factory image. But then again. That answer is again besides the question. I'm not asking to flash a factory image. I'm asking if using a custom recovery would make it possible to still manually flash OTA's. I'm not gonna flash custom rom on the nexus either. I love the stock rom, smooth and fast but that's again besides the question

2)I believe you asked what the "latest and best" custom recovery would be. (matter of opinion) I was simply trying to simplify your quest, by linking you to a toolkit that will do it for you.( wugfresh will install the latest version of twrp.. It will do much more than root your nexus... if you explore it) the check box under root. ( I personally don't use it, I prefer to do things the hard way)
3) I agree the stock ROM is "super smooth, and fast", (stable) that's why I personally use the xposed framework, with the stock ROM (updated to 4.4 krt16s, with the elementalX kernel 2.2)... And yes rooting, AND removing a system app (pinyin keyboard), will make an ota fail... Don't think you asked that... I don't know about flashing an ota thru a custom recovery, never done it, but it definitely sounds like a sketch idea to me. IDK why you wouldn't just flash an update.zip. ( pretty much the same as an ota...) If you are running a custom recovery... And if you really want that stock ota... flash-all.bat is your best friend...
From some guy who's been flashin stuff, and things, since his og galaxy nexus... Owned every nexus device since then, and haven't bricked nothing yet.
Just trying to help.

A few dumb Nexus questions

Never owned a Nexus device due to the lack of storage (16GB not enough). Got the GNex for my mom and just got a few questions in terms of root/OTA. It's a canadian GNex yakjuux that i updated to 4.2 and converted to international yakju. I love AOSP based phones but 16GB is the only thing that prevents me from hopping on the Nexus train. So CM/AOKP on an S3 is as close as it will get until Google gives more options.
I was thinking of installing CM/AOKP but I don't think she will need that many features so I want to keep her stock to make it simple and bug free as possible. I want install TWRP and root the phone and that's it.
1.) I know rooted phones don't get OTA's do to locked bootloaders and custom recoveries, is this the case for the Nexus line?
2.) If OTA download will they install themselves on a custom recovery?
3.) Will the install replace the custom recovery back to stock?
1. you have to be completely stock, you can be rooted but everything else including recovery kernel, radio, etc must be stock in order to get a OTA
2. if you download the OTA zip you can flash it in recovery but even then you can ONLY have root/custom recovery other than that you must be completely stock
3. Yes the custom recovery will be replaced by the stock
PS next time search the forums these question have been asked multiple times, and also post in the correct section next time...

[Q] Do I have to flash stock recovery now to get OTA?

Previously, I asked something similar when the JSS15R was released. I was told that when OTA is installed, it overwrites the custom recovery with the stock one and that we can flash the custom recovery later. But why does everybody seems to be going back to stock version.
Also, if I go back to stock recovery will the root work?

Flashing back to stock recovery will insure a successful installation. Usually if you're on a custom recovery it'll go through the process of installing then fail towards the end. You can always flash back to custom recovery after you confirm the installation has gone through.

Traditionally stock recovery is what OTAs work with and what the manufacturer tests with so you are assured everything will work.
That being said, on a platform by platform basis, it is possible the custom recoveries will flash the OTAs fine.
From past OTA updates, people have found custom recovery successfully flashes the OTA for the Nexus 7 2013.
You can flash back to stock or use TWRP/CWM. Either will work (I've tested on WiFi/Flo but I believe folks on LTE/Deb have said the same)
Thanks. flashed the ota with latest twrp along with super su. Everything works fine.

[Q] Rooting, OTA, Recovery

Hi everyone,
I have some questions that will help me understand a lot more regarding rooting, unlocking, custom ROM's etc.
I have read a lot of things in the forums, but despite the trove of information, it's still not always easy to piece together what you need to know in order to understand or feel confident about the process. Sometimes I find answers, but they are a couple of years old and no indication they are still currently valid, etc.
- Is there any danger to sticking with the Stock Recovery as opposed to using ClockworkMod or TWRP if I am only going to be rooting, unlocking and using official Android OTA releases? If I remain with Stock Recovery, do I lose any rooting related features, or the ability to perform certain functions using NRT later?
- I want to confirm, if I keep the Stock Recovery and then I use NRT to root, unlock and flash an official stock Android release, should I then be able to get official OTA updates without having to wipe the device as I would with a Custom Recovery? I believe I would just need to unroot before the OTA, then reroot immediately after, correct?
I did read a thread that talked about how to restore stock recovery without losing data... but I'm using NRT and want to stick with that, which I don't think offers that option. I just want to keep it as simple as possible since I'm new to this. I'm afraid that if I mix methods, it will cause issues.
- If I decide to try an alternate ROM such as CyanogenMod, is that when using a Custom Recovery will become absolutely essential?
Under this scenario, would updates to CyanogenMod (or the other popular ROM's) require wiping the device data?
Thanks to anyone who can confirm if I'm understanding this all correctly.

I'll try to answer as many of these as I can.
1. There is no danger in sticking with the stock recovery, but you do lose some features - most notably stuff like backup/restore, and a whole bunch of advanced features that are either not present in, or are hard to get to in the stock recovery. I'd suggest TWRP - works great with mine, even though I use CWM for all my other devices.
2. In theory yes, not sure about this though.
3. Just get TWRP makes life easier.
4. It's still not essential, but VERY useful unless you want to push every zip through ADB instead of just hitting the "install zip" button. As for the updates - if it shows up in the update section it won't wipe your data, if you have to flash through a recovery it MIGHT, but not 100% sure.
There you are - feel free to correct me on any of this
Sorry for asking this in others thread but I just want to know something..
I am currently on aicp which is 4.3.1..if I want to update to kitkat..what method can preserve the data on my sdcard?
Well, I did have TWRP installed, running stock 4.4 and rooted and unlocked... then the 4.4 build got a minor OTA update.. and guess what?
Can't install it without losing all my data, because TWRP is installed. At least, that's what I read.
So, I decided TWRP had to go.
I can't keep wiping the device every time I do an OTA, so that's really the main thing I want to avoid.

You can install the ota with twrp.
You can also replace twrp with stock recovery without wiping the device.
The only process that wipes the device is unlocking the bootloader,. If you leave it unlocked you can switch around as much as you like

[Q] Samsung S3 (cyanogenMod) unlock

Hi,
I bought a locked Samsung S3 (At&t). It is rooted with cyanogenMod 10.2 Android 4.3.1. All i was trying to do is unlock it so i can use it with other carrier. So i bought the unlock codes for 30 bucks but later i found out that the unlock codes only work with Stock rom. I am not an expert at this Root, Custom Rom...stuff, but not idiot either i can follow step by step directions if anyone knows how to make this work. I would like to use the custom rom though, so do i have to recover in stock rom, unlock the phone using the code and than install the custom rom again?
Plz help
Hi!

Yes, that is what you will need to do. As you can only enter an unlock code on a stock ROM (or one of the numerous custom ROM based on the stock one), you won't be able to make it work on CyanogenMod or any AOSP derivatives. You will have to revert back to stock, then (if you want to try a cutom ROM) install another custom ROM of your choice, be it CM or anything else.
Though if you currently have CM installed in your device, you most certainly already have a custom recovery (TWRP, CWM, PhilZ Touch...), which make it even easier for you to flash ROMs at your will -- the step of installing a custom recovery is already done. So browse the AT&T SIII Android Development forum, choose a stock-based ROM, install it -- pay close attention to the installation instructions in the ROM's thread --, unlock your phone; then repeat those steps to install another ROM if you want to.

Could you please direct me to how to unroot? I am able to go into the recovery mode but not really sure how to go on from there. I appreciate the help.

Before you flash a stock ROM, you would need to check what bootloader your phone is currently on as flashing the wrong one could cause your phone to brick or become unusable. Custom ROMs like the CM you currently have do not have their own bootloaders but rely on manufacturer's bootloader to run. The bootloader, quite simply, is a small application that loads the operating system and all other applications & systems required for the phone to run once it is powered on. Therefore, with a faulty bootloader, your phone can not gather all the resources required to power on successfully. If your phone is running on the 4.3 bootloader which would be the case if it was on 4.3 before the update to a custom ROM, then you would have to return to stock Android 4.3 which is the latest OS available for the AT&T GS3. However, if it has an older bootloader, then you can flash Android 4.1.1 via Odin.
There are different sets of instructions for either system so I would suggest you check your phone's settings and advise the OS parameters you can see there so we can steer you in the correct direction.

Did the phone originally have 4.3? or did it have an older version before you installed CM 10.2. This would determine how you would go about it.
Also is there a custom recovery like clockworkmod installed?

trouble with official update on rooted m9

my m9 has received an android 6 update massage. but after installing, the phone restarts in custom recovery.

thank you.
i just want to upgrade to android 6.
i know that i can flash custom roms with custom recovery. is it possible for me to download an stock system image and flash it with custom recovery the same way? i do not want to make everything back to its original. i want a rooted android 6 with custom recovery.
-----------------
i had some search. if i upgrade to stock android, then i will have to root my phone again and for that i have to flash a custom recover again. i searched and find out that android revolution custom ROM is a good choice for ones how wants to keep HTC Sense.
thank you for your support.
Check here for possible stock system images and recoveries...
You should be able to flash a stock system backup from this thread...to include recovery....then take your OTA....and flash TWRP afterwards....
Just make sure everything matches your carrier....cid/mid....so the outcome is favorable...g
http://forum.xda-developers.com/showthread.php?t=3132698
You'll quickly find, if you haven't already, that the latest Android Revolution HD (v20) requires you to have the latest firmware. Flashing it without it will throw your phone into a boot loop.

If he has removed his carrier's bloatware as well as the custom recovery, would he have to flash the system image also?
Or just flash the recovery?
I am asking as many AT&T users often root to remove AT&T bloatware, like I did. I used HTCDev.com to root, and my bootloader is unlocked.

Flashing a stock RUU will guarantee that the system and recovery are completely stock...
The OTA scans the device prior to update and will detect any software that isn't signed or official...
I'd RUU back to stock...then OTA will prompt....and won't get stuck trying to update the system partition...g
