After Unlock Bootloader How to flash Recovery for Z1 C6902 14.2.A.0.290

Dear all, I just Unlock the bootloader my Z1 C6902. And I don't know how to flash it Recovery. Anyone have it recovery?

You could try the "ROM-Manager" - App.

It's a little more complicated on Z1 as compared to other fastboot devices, you can't simply flash a recovery to the recovery partition because the Z1 doesn't have one, so the solution is to flash a kernel partition which has been modified to do a check for if the user wants to load recovery before kernel startup. There are a couple of those in the Android Development and Original Android Development boards in this section.

After flashing doomkernel, install SuperSu1.85.zip & su-bin-3.1.1-arm-signed.zip...
Root is tricky in 4.3. Even after rooting you will not be able to mount the /system partition in RW mode, but with the root you can get titanium app to work.

still can't

ZR-lockeddualrecovery2.7.124-BETA.installer is for locked bootloaders. read OP before doing anything otherwise you will brick your phone.
You can flash recovery kernel. see in dev forum

@sijav isnt NUT's recovery for locked BL? correct me.

what's differences between BL and UL for you guys?
UL can flash kernel.
BL cannot flash kernel!
what's recovery?
some binary files that should be called before calling and starting system so it's pretty good to start in kernel before trying to start system.
but what if we can't modify the kernel?
yet we can modify the system and put some binary files in stock chargemon (when the phone trying to figure whether goes to offline charging or not) so it starts first in whole system and wait for a key, if pressed just execute the recovery!
so again, can something that specifically build for LB be flashed or run on UB?? my answer is mostly yes.
can something that needs flashing kernel or other things than system and data on LB? my answer is mostly NO
is [NUT] recovery for both ub and lb? yes! if you don't have recovery on kernel. ( or else you have two recovery one in kernel and one in system and 3 seconds delay in each starting nothing else)

[Q] Can anyone root android L ??

Finally we got Android L, so can anyone root it ??

On UB, flash twrp recovery using fastboot (fastboot flash boot recovery.img). Then flash super su using recovery. After that flash back kernel using flashtool.
I'm still figuring out how to flash a twrp recovery on ub

If this root method is working, you can try flash recovery in FOTA partition by for example Xperia Recovery Manager.

If you have allready rooted phone, use http://forum.xda-developers.com/showthread.php?t=2859904
To create rooted update file and flash it via recovery.
You might need to downgrade,root and update via your own lollipop package.

After unlocking I suppose you are on stock or stock based ROM. Flash tangerine using fastboot. And install any lollipop ROM through recovery without booting into stock ROM.

[HELP] Root access on Marshmallow 6.0.1

Hi,
How do I root the phone now, after upgrading to 6.0.1
I've tried the method mentioned here: http://www.guruswizard.com/2015/12/root-android-one-devices-on-6-0-1-marshmallow.html to root my karbonn Sparkle V
and it wasn't successful, and I've lost all data after unlocking bootloader [I've got desktop backups though]
When tried to flash that modified boot image mentioned in that page, I am getting this error:
target reported max download size of 134217728 bytes
sending ‘boot’…
OKAY [0.515s]
writing ‘boot’…
FAILED (remote: size too large)
finished. total time: 0.577s
Is it for 2nd Gen devices? Did anyone get root access on their 1st gen sprout4?
So how do I root my phone now?
Thanks.

Cody kernel: http://forum.xda-developers.com/cro...elopment/kernel-cody-kernel-07062015-t3128888
Supersu: http://download.chainfire.eu/743/SuperSU/BETA-SuperSU-v2.52.zip
Flash both of them, and enjoy root
Or if you want root on stock kernel
Use supersu 2.62 from attachments of this thread
http://forum.xda-developers.com/showpost.php?p=64161125
It will patch the kernel automatically and root without modifying system
Hope that helps

is there any way for rooting with custom kernel

Custom kernel and Custom Recovery both are different things,
Custom kernel is the device supreme commander which controls all processing, ram, fluidity and many others fact you can tweak it but cant use it to root the device..
On other hand Custom recovery is used to recover phone by flashing ROMS, zips , img etc.
So you can flash supersu from custom recovery and root your device
But if you already have custom kernel installed on device then its clear that your device is rooted, as bcoz. your custom kernel gives you some extra tweaks which is given after root.
So device emulates that you have custom kernel so your device is also rooted..
I think that you have understood....
BEST OF LUCK FOR YOUR FUTURE:good:

You can flash one using fastboot. Or instead of flashing you can even use the command "fastboot boot recovery ......... " (replace..... With name of recovery image file) . Once you are inside the recovery flash supersu zip normally and you'll root your phone without installing a custom recovery.

Hi,
Thanks for the info Atishay. How do you undo root if required post this method. Also does rooting with the above method affect future OTA installs?
Thanks.

Go to Supersu app and click the option for full unroot/cleanup. That'll do the trick. Also, if you are rooted, you still receive OTA. In fact I received the Lollipop OTA while I had a custom recovery installed. The only difference that made was that after downloaded when the phone rebooted into the recovery for installation, the OTA zip wasn't installed. So you can unroot, keep the stock recovery and kernel and locked bootloader (you can relock it using fastboot) then you'll receive OTAs. However, I'd suggest, you install a custom recovery and simply flash an OTA when it arrives from the forums. Hope that helped you.

Very helpful indeed! Thanks Bud!
