Hi, I am new to the android scene and have a few questions.
Just wondering about the procedure for updating a rooted device, specifically the nexus 7. After I receive my nexus 7, I am planning on unlocking the bootloader, flashing CWM, and then rooting the device. I am not planning on using any custom roms. I am just going to be using stock JB.
If in the future I want to do an OTA update, what is the procedure for this?
From my understanding, it seems this is the procedure for doing an OTA update for rooted nexus 7:
1. unroot the device? (how do you unroot the device?). is this necessary?
2. use cwm to flash the stock recovery, because you won't be able to get the OTA with a custom recovery such as CWM. Is that correct?(also, where do you get the stock recovery??)
3. apply the OTA update. root will be gone.
4. flash CWM and re-root the device
And once I have succesfully OTA updated the nexus 7, re-flashed CWM, and re-rooted back the device, will I have to start from scratch (lose all data, settings, apps, etc?). I know unlocking the bootloader will wipe the device, but will the OTA update process require me to start over?
If I am missing any steps or have some things mixed up, please let me know. Also, if I were to use an OTA root keeper, what would the procedure be like or how would it change the procedure I listed above?
Thanks.
Haven't got my Nexus 7 yet but it looks pretty simple according to this thread: http://forum.xda-developers.com/showthread.php?t=1764794
Basically just need to have OTA RootKeeper installed beforehand, then disable signature verification in CWM and patch the OTA update. Then OTA Rootkeeper can restore root.
HTH
I know that I can't get OTA normally if I have any system level modifications like root or xposed installed.
However, I came across this thread which lists both, the stock firmware images and individual OTA update zips.
With the zip for OTA in hand, will flashing them on a rooted stock device cause problems?
You can install the factory images but it will be a clean install. You will have to root the phone after. You can learn how to flash those images here, http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
No. You can't flash an OTA if you're modified. You must flash the factory images.
Thanks! Guess I have to download the full thing everytime.
Thanks!
I plan to get my OP5 today, and will update it before I root it, but I'm curious about future updates. Is my understanding correct that the OTA will fail, and the only way to upgrade is by waiting for the full stock ROMs to be posted here to flash in TWRP? From the previous phones, how long of a delay is there typically between an OTA and when we can flash it via TWRP? Does the full ROM that you flash also include the modem/radio files, or does that need to be flashed separately?
If you are stock and not rooted: updates come OTA as incremental updates. Small filesizes.
If you are stock and rooted: updates come OTA as FULL zips. Full ROM size. 4.5.2 for me was around 1.6GB in size.
Both will come through the official OTA mechanism. When the device reboots and installs, it runs on TWRP automatically without any manual user intervention.
tl;dr: Will still be OTA, but bigger filesizes. You will have to re-root (re flash SuperSU, Magisk, whatever)...

I'm stock and rooted, the OTA came as a 36MB update.
ota
I just rooted and wanted to update with OTA to 4.5.2, it rebooted into twrp and did something for a second and went back to the normal menu. I then rebooted and it told me that the update did not apply. I just flashed the 1.4 GB OTA and rooted over again, for the next update, do i have to wipe before i install the new OTA manually or can i just flash the never big version over without having to wipe it?
Do I have to flash TWRP for the OTAs to work once rooted? Or will they still install with stock recovery?
I rooted with "fastboot boot TWRP.img" instead of actually flashing TWRP to the system...
1. make backup
2. save it on your computer
3. flash latest TWRP - reset back to recovery
4. flash OOS 4.5.2 Full Rom Zip and SuperSU or Magisk
5. Wipe Dalvik & Cache
6. make new backup if everything works fine, so you have it just in case

If you are rooted, the phone automatically chooses to download the full OTA zip.
I want to root the phone and unlock bootloader. But firstly, i want to make backup all the settings/applications etc. How can i do that? I am full stock now
You can try Helium backup by clockworkmod. It is supposed to be basically a more friendly interface to `adb backup`.
For the record I couldn't get it to restore properly when I rooted my Shield TV, but I was probably doing something wrong.
I plan on rooting about to do it now. When another OTA update come along from above says I will get the full download but it will not erase any data or setting, right? Will be just full update but all will be intact?

As part of rooting, you will need to unlock your bootloader, which will wipe all data on the device. This is a one time thing.
After that, when you get OTAs, your data, apps, etc., will be intact, but it will overwrite several system partitions (that's why it's the larger download). So you will need to reinstall TWRP or whatever recovery, and reflash your root zip every time an OTA comes along.
If you have the space, it doesn't hurt to make a TWRP backup before installing the OTA.
Hope that all makes sense!
Hi, I have a european S8+ fully rooted and with TWRP.
Everything's working great so far but I read somewhere that I won't receive further OTA updates.
Can I install them manually with TWRP?
If yes, 3 questions:
1. Where can I get them?
2. Do I need every single update or are the newest update always containing the older updates as well?
3. Do I lose root or TWRP after installing an update?
I've rooted with Magisk by the way.
Typically if you're rooted and modified the system partition (BusyBox or twrp or whatever) the update will not install in stock recovery. Usually you have to unroot reinstall stock recovery and flash ota. There's toolkits out that can do that. Or you can just find an awesome rom like a rooted debloated rom thats just recently updated and just flash that. Or you can what till somebody snags the ota update location then posts that.
I received ota update notification. I downloaded the zip, it is npn25-37, currently my phone is on npn25-33. I have magisk root and twrp. I wonder if I can flash the ota update zip in twrp? Thanks

It will not work, OTAs require the stock recovery. Since you hace TWRP there is also a chance that it might have mounted your system before, so your system image isn't vanilla anymore and the OTA will fail to apply. First try flashing stock recovery from here (search for the version you currently have, which is -33) https://forum.xda-developers.com/g5-plus/how-to/firmwares-moto-g5-plus-t3593160 and then apply the ota. Since the firmware you're on is quite outdated, you'll probably have a couple more OTAs on the way.
Now if that doesn't work, you'll need to back up everything you have (apps and data) and flash system, oem and recovery, and then apply the ota updates, then restore your data.
