Is it possible to restore the recovery image to the default? And where can I get that recoveryimage then?
If your using a magic, the easiest way to do this is to get the stock NBH file for your carrier or someone's stock Nandroid backup. I don't know where to find these files, I have the one for Vodafone UK (Not mine, got it off of another forum, so don't credit me for it). The others you will have to search for, and some of them are not that easy to find.

Hi all, I just wanted to ask this before I start flashing custom ROMs:
If I want to restore the factory image, would I be able to just flash the zip from the google dev website for the Nexus 10 (https://developers.google.com/android/nexus/images#mantaray) In recovery?
I noticed that in the contents of the file it has a new recovery image and all so I would imagine that I can't do this but thought I would ask. If no, what is the best way to get back to stock? I know there are some guides with several fastboot commands to erase everything you've got and then build it back up from scratch, but is there no other way?
Thanks in advance!
Personally, I used the [Nexus 10 Toolkit]. It really can't get much easier than that.
It provides everything you'll need to download and flash the stock image/recovery, re-lock bootloader, etc. Not to mention all the other fun stuff you can do with it.
This is a pretty specific question and i'm not sure this is the correct place to ask this but i recently installed the stock rom (Via Zip) on this thread: http://forum.xda-developers.com/showthread.php?t=2527806 . I flashed just the rom NOT including the bootloader (Because i don't know what it does) and the .97 radio because there seems to be some issues with it. Now, everything is working perfectly as it did before. What i'm wondering is after today's random new 4.4 factory image and ota update from Google (I think its krt16s); i know they are probably going to compile a flashable zip, and if they do what exactly do i need to do?
I'm extremely weary when i do these kind of things, the last time i flashed any sort of rom was on my OG RAZR. Would i have to install that new bootloader? (Also what exactly does it do) And would i have to wipe?
I can make the radio judgement on my own but i'm just not entirely sure.
If anyone could answer my questions that would be wonderful, i'm also sorry for posting this here, i'm not allowed to post in that thread because i'm "new" to the site.
Thanks!
you dont have to sorry as you are in the right section for asking questions.
You can either wait for a day or two for someone to post a flashable zip file. If someone do post it; all you have to do is copy it to your phone. Reboot to recovery mode; make sure you have cwm recovery installed. From there choose "install zip" > install zip from sdcard, choose the flashable zip. Once it finishes installing, clear cache partition and reboot. You will not lose anything in the phone.
If you want to install the new krt16s stock update. First, copy all of your files (pictures/music/data etc...) to your computer. This will wipeout everything. Download the image file. Open it with winrar or 7zip. Extract all the files to a folder. Connect your phone to the computer and reboot it to bootloader. Run the "flash-all.bat" file from the extracted files. Wait for it to finish. It will update everything (kernel, bootloader and the new 4.4)
You should know what something is before flashing them wildly, that's the easiest way for people to brick their phone by flashing something incompatible with their devices. Bootloader is the main program that boot first when you turn on to phone to make selftest and boot normally into the operating system kernel, with Nexus you can use it boot into recovery and flash images to partitions as well. It's very recommended to update it along with new Android version or you may run into issues. You should already know this since you had to access the bootloader screen to boot into the CWM recovery.
Stick with using CWM for now and flash the flashable zips. Just make a full backup of your device you can always restore it later. Just know that unless you flash radio separately (aka baseband), roms generally and should not come prepackaged with the baseband, so it is not affected when you flash a different rom, you have to upgrade it manually.
When you flash a new Android version, usually its recommended to do a factory reset in your recovery to avoid issues.
Installing factory image takes a few more steps and required using fastboot, but if you want to check the link in my sig. Also I recommend switching to TWRP recovery, but that's just me.

I see, me personally, I'm not very fond of using adb; I haven't used it at all prior to yesterday. I may try this out, but should someone post the new kernel, boot loader, 4.4 and radios would that be the same as flashing the factory image?
This probably seems like a really stupid question but I wouldn't be smart to try to download the ota directly from the phone (via check for updates) would it?

You need to learn to use adb and fastboot if you want to be able to do advance things with the phones, or just avoid flashing too much, because once you run into trouble (especially due to using toolkits), you will not know how to recover your device.
If you want your device to be stock and able to receive OTA updates, in addition you also need your stock rom to be an "odexed" version, some roms are "deodexed" which will not receive OTA. You also need to have stock recovery, which CWM isn't.

Thank you! One more question, let's say I revert back to my nandroid back up. I backed my ROM up on Android 4.3 rooted and unlocked with CWM. If I flashed the 4.4 factory i image what exactly would happen? Would I boot into 4.4 absolutely stock? Or would I end up with 4.4 unlocked etc...?
Thank you for the help I really appreciate it. ☺

When you flash factory image (using fastboot method), it will wipe your entire device and all user data, and you will boot into stock. Except if you do it manually you can prevent datas from wiping, follow these steps and pay attention to the red texts.
Sometimes apps data from older version can cause issues with newer version though, so a clean install is always best.
But if you have custom recovery, you can flashable stock roms, such as this one by fireb33, it's essentially the same as stock. Get the "odexed" version which is required to get OTA updates. Some peolpe say they can get OTA with custom recovery, but I have never tried that. The safest bet is to use fastboot to restore to stock recovery. You could also use custom recovery to flash OTA update packages to update versions that way.
As for backing up, people tends to call the backup "nandroids". After you do backup, if you're doing something that required the device to be wiped, you need to copy the backup to your pc. The CWM nandroids are usually located in 'clockworkmod' folder, but if you don't see it, search in "/data/media". I do not use CWM so I don't know what it allows you to back up, but generally "boot" (which is the kernel), system, and data partitions. It will not restore everything to stock such as your radio (baseband) or recovery.
I highly recommend switching to TWRP recovery, it will make flashing a lot easier.
I want to resell my XT1562 and need your advise on howto make it stock again.
I noticed that the backup I made with TWRP doesn't include the original recovery.
Which files do I need to flash to restore the recovery software?
Thx

Hi all,
* Do i have to unlock my Bootloader before I root my OnePlus 2 phone ?
** If i'll have to erase all data in order to perform Rooting or Unlocking What is the best backup tool to use in order to restore everything ?
*** Where i can get an original OnePlus 2 rom to download ? (If i'll need)
Thanks a lot !!!
Best,
Jonathan
Yes. You have to flash SuperSU using TWRP, and to use TWRP your bootloader needs to be unlocked. Try out Helium Backup. That's what I used to backup my phone without root. It only backs up apps and app data though. No system data. If you need to backup SMS and MMS messages, use SMS Backup & Restore. You can download the stock OPT OxygenOS from here, though I would make a Nandroid backup of the stock OS in TWRP before you do anything first. Good luck!
Thanks for the quick response,
Another quick question, after rooting the phone will I able to copy into "/system/media/sounds/ui" folder without problem ?
The main idea is to add a poweron.ogg sound file in order to hear something during the poweron
Thanks again
Of course! Root gives you access to all system files on the device. You'll just have to use a root file explorer such as root browser which is probably my personal favorite. Many people also use ES Files Explorer. Just be careful if you do use it because you have to enable the "Root Explorer" tool.
Hi again,
Have you ever try to add sound during the start up?
Nope. Honestly never really had a desire to. I'd be surprised if there wasn't a tutorial out there on how to do it though.
I succeeded to unlock my OnePlus 2 ... using fastboot....., now do i have to install TWRP or to stay with the OnePlus 2 original recovey mode ?
What are the advantages for doing that (TWRP) ?
Thanks
You need TWRP recovery to flash the SuperSU app. TWRP is also what you use to flash custom Kernels or ROMs. If you want, you could do what I did and just boit to TWRP instead of actually flashing it to your device. Then you can flash the SuperSU app and have root while keeping the stock OPT recovery. Then, if you want, you can go get Flashify, purchase and unlock the premium features within the app (absolutely worth it!) and use it to backup the stock recovery and then flash TWRP so that you can revert back to the stock recovery if you ever want to. If you need more detailed instructions on any of that, I can submit another post later when I can get to my computer.
Where can i find stock recovery for OnePlus 2 (in case i'll need)?
I found this in XDA forums:
http://forum.xda-developers.com/oneplus-2/general/rom-mirrors-official-oxygen-os-roms-ota-t3209863
That forum post is just for downloading the stock ROM. Like I said in my last post, bootong to TWRP instead of flashing it and then using Flashify to backup the stock recovery would probably be the best method, however it seems like you can download the stock recovery from here. I personally have not used that download before so I cannot vouch for its legitimacy, however it seems other people have had success with it.
Which Flashify tool to use, which author (Christian Göllner or Nightshade Labs) ?
Here ya go!
https://play.google.com/store/apps/details?id=com.cgollner.flashify
You can also use that app to flash the TWRP recovery straight from your phone.
I've been doing some research to understand rooting, unlocking, and other Android stuff, but one thing I still haven't figured out is how people "make" a stock recovery image, so that for example after flashing TWRP you can go back to the stock recovery (which I read is one way to install future updates). I think in general it would be possible if rooted, but for ZE551KL, so far I'm pretty sure the only way to root is to unlock and install TWRP. So, how would one make a backup of the stock recovery? If it can't be backed up without root, do people get it from somewhere else, firmware releases maybe? I looked but seems to be mostly a giant system.new.dat file...
Past that specific question, where can I learn more about the partition structure of my phone? Like where is the recovery in the file system?
Thanks for the help!
