Recovery-from-boot.p

Hello, i flash stock 4.0.2 on my nexus through fastboot.
Today booted cwm (fastboot boot ....) to create nandroid backup and then have rooted.
I have installed root browser lite but if i go in /system i don't find recovery-from-boot.p
It's normal?
Stock 4.0.2 have downloaded by Google's site.
Thanks in advance.

It's normal. If you flashed the stock image, it won't be there. If you flash an earlier stock image and upgraded via OTA, it will be there. No need to worry about it.

How important is this file ?? ("recovery-from-boot.p")
i have update.zip from manufacturer. Inside zip file, there is folder "recovery" containing "recovery-from-boot.p" and folder "etc" containing "install-recovery.sh"
If i delete recovery folder & sign the file again & update it, will it work?
What difference does it make?
is recovery anyway related to rooting the mobile?

Those two files do nothing except yo reflash the stock recovery every time you boot android. They don't exist on stock roms, but rather are put there by ota update files. They are safe to delete.
P.s. no need to resign the zip if you are using CWM.

Not sure what that device is, but:
Root is just two files place on your system:
/system/bin/su
/system/app/Superuser.apk
You will need to find a way to place them there, either by using an exploit to give you write access to /system, or by booting an insecure boot image if you can. Don't think I can help you any more than that without knowing the device.

The device trying to root is Karbonn A9. We have rooted the phone by replacing it with another recovery.img. To unroot, we used update.zip given by Service centre. Inside that, there is ""recovery-from-boot.p"" inside recovery folder. After updating using the update.zip, we are unable to root again. If delete recovery folder in update.zip, & update the phone again, will it delete the "recovery-from-boot.p" & will it possible allow us to root again?
Other doubts:
Does replacing recovery.img via fastboot change IMEI number? One of our developer got his phone bricked. he took his phone to service center. They said, they don't have their IMEI number in their database.

As I had mentioned earlier, those files do nothing else aside from re-flashing the stock recovery on every boot. If you delete the folder and re-apply the update, chances are the update will not work -- not because you deleted the folder, but because you already applied the update.
If you want to root again, you have to follow the procedure you used the first time you rooted.
No, the recovery does not contain the IMEI, so flashing a new recovery will not affect the IMEI.

I have just find out that on recovery mode, there is an options to "apply update from /cache".
This link show how to do it without CWM:http://blog.talawah.net/2012/07/how-to-manually-ota-update-your-galaxy.html
However, It seems that I need to root my phone to move the update file into /cache folder.
Please, Does someone know how to write the "update.zip" on /cache folder on the phone without rooting it?
thanks in advance

There is of course a method: You can flash factory images via Fastboot mode.

Hey I am also looking for this....on a side note are you looking for this because of wifi issues? has anyone found a fix?...pretty bummed wifi is not working on this thing

Could you install the dumps in http://forum.xda-developers.com/oppo-n3/help/looking-dump-boot-img-t2998030 Post #5, then unroot and run the OTAs to get you back up to current?

I doubt that any stock rom will flash with twrp recovery....in the past with oppo phones (n1, 7a) its always needed stock recovery to flash stock roms...I guess we just play the waiting game until someone can upload the boot image from the updated rom. I'm pretty sure flashing that alone will get wifi back up and running. 07 Or if someone has the stock recovery they could upload....I am unsure if you can just rip it directly out of the rom and flash it....Also on oppo forums they have posted the rom for 5207 I am also unsure if you can flash that to the 5206.

The zip in that thread is images to flash in fastboot?

...
I would think you would have to flash each image individually.... system, boot, recovery ....unless if we start by flashing only the unmodified boot.img to see if it will fix wifi....but i doubt it because i suspect the wrong boot image is what screwed up wifi in the first place...someone please correct me if im wrong

Yes, you're right; the boot image is not compatible with the upgrade; so downgrade to get root. I'm working on trying to upgrade again with the OTA upgrade and then getting the new boot.img and rooting that. More soon I hope!
FYI I tried your images, Lum_UK and found that I couldn't flash boot.img with fastboot, BUT I could dd them from within recovery, so I got myself up and running again.

Yes you'd have to flash all the images by hand one after the other.
edit: Replied before seeing babelmonk's response, please ignore this post.

I can't get the OTA to work even after downgrading, but I do have a working system running 141228 with that hacked kernel, root and non-broken wireless.
Anyone want a nandroid of it? It's a slight upgrade at least

Thanks for that, though I haven't tried it yet. Can I ask what it changes? Is it worth the upgrade? My original firmware +root seems to work pretty well already so I may well leave it alone until L or CM comes out.

I have no idea what it changes as it's the firmware my International N5706 was shipped with when it was released last week. It may be different to the US model (though I believe the only difference between the two is the baseband) and is definitely different to the N5707 for Chinese users.

Dude, thanks!!! You saved my life!

How to roll back to official build after flashing community build?

From what I've read it seems that you have to unlock bootloader to do this. Which is something I am finding hard to digest.
Do I really need to unlock bootloader to flash official build? Or is there some official way which I can't seem to find?

Didn't find a way without data wipe.. but my bootloader is locked and never rooted on this OP3, as long as your OP3 is encrypted I don't think there is a way without loosing data.

I have completely wiped the system using stock recovery and now I can't flash anything. When I try to sideload it says can't read the zip file.
I've tried with both community and official zip.
Any idea what's going on?

Seems like adb drivers issue (on Windows?) many are facing. What worked for me is to cut/paste zip to desktop and then immediately cut/paste back to adb folder (without closing command prompt) and typing adb sideload zip again..
See if it helps..

Flash TWRP on RUU'ed Stock ROM without PC?

Hey,
Quick question, I'm away on holiday and had to use an RUU to reset my phone completely back to stock. I don't have my PC with me but was wondering if there might be any other way to get TRWP installed so I can get back to custom ROM's before the end of my trip?
Regards,
Ravi

I've described how to do this for CM-based ROMS with Samsung devices. Unfortunately, I know of no way to do this for the HTC 10. The issue is getting it rooted. My understanding is that the Sunshine app can root some 10s, but not all. You could try that. When you run the app it will do a series of tests on your device. If it cannot be rooted by the app it will give the message, "Root is required first." Otherwise, the app can root your device and proceed from there. Once rooted you could then use Flashify to install TWRP.

Thanks guys!!
I'm trying to figure out, if I want to flash just the recovery with the no wipe zip, can I delete all the other .img files within the zip or do I have to edit the Android-info.txt for the corresponding lines?
No issue in flashing the no wipe file as it is, just curious for future reference if I wanted to create easy 2PS6IMG.zip's in the future.
Sent from my HTC 10 using XDA Labs

I simply take the firmware.zip from OTA, delete all .img files, rename twrp.IMG to recovery.IMG and repack it to 2PS6IMG.zip
You don't need to change the android-info.txt as partitions without images won't get wiped, even if it says so.
You can flash Boot, Recovery and..... And.... Which was the third one? Without S-Off or signed firmware package.
