nexus 5 autoroot: downloading root.img failed
Hi Chainfire, thanks a lot for the program!
I actually just paypal'd you a symbolic euro for all the effort.
But after all, de root did not work completely yet,
after the selection menu 'unlock bootloader YES/NO' (I choose NO btw, will stay with the stockrom for a while),
i get the error message
' downloading boot.img FAILED (command write failed (No such file or Directory) ) '
I don't see anyone else reporting this problem on the thread, so my question: what could cause it? What can I do?
Extra inf:
I am on a windows system (7) and had the trouble with usb-driver that was not installed first, dont know if that influenced it?

dont use root toolkits, as you will learn nothing, then think your phone is bricked when it needs some simple upkeep. its a nexus, its easy to root, no toolkits needed, unless you just dont want to learn anything/the basics.
Hi Simms22,
You're absolutely right, thanks for your remark.
Just for the sake of explaining why I tried the toolkit:
I literally just bought the phone (<24h), and I only wanted a quick access to the SU-privileges. I didn't want the unlock the bootloader and go for custom ROMs (yet).
I did this with my previous phone (sony xperia), and all the trouble I had with the process took me 1,5 full days to get the thing running again.
Just to say, I dont want to go all deep into it right now. If I could root my nexus with the tool, that'd be great, but if it isn't possible, I will first explore my new phone as a ordinary user I guess. Going trought all the flashing-nexus-infothreads if for later on.
Thanks for the advice!

Unlocking bootloader and using custom ROMs etc on a Nexus is no where near as complicated as it is on a Sony device (or any other) - in regards to if anything goes wrong, it usually takes 5mins or so to start from scratch on a Nexus again compared to Sony/Samsung etc.
Also remember, there is no warranty issues on a Nexus device either. So you can unlock/lock your BL as and when you see fit.

Ok, thanks a lot for your reply. It gave me confidence to try the 'unlock bootloder'-option, which worked like a charm
I am enjoying now the perks of a good titanium-datatranfer; I like!
See you around in a few months when I try custom ROMs!
Device already unlocked?
Hello,
I am also new to gaining root access on android devices, and I could use some help.
I have a Google Nexus 5, and followed the steps using CF Auto Root, but it only says <waiting for device> when started and wont proceed with anything. I have the device in bootloader and it tells me the Lock State is already unlocked. I haven't left CF Auto Root on <waiting for device> for more than 5 minutes, assuming it shouldn't take that long.
So I went ahead and installed SuperSU via Google Play to see what I could do, but SuperSU tells me that there is no SU binary installed, and that if I just upgraded to android 4.3, I will need to manually re-root. However, I have android 4.4.2.
I have used two different root checking applications, but they both told me that my device does not have proper root access.
Superuser also doesn't seem to work. It wont inform me when I try to use an app to perform root access actions.
Any help on what I could do next would be appreciated.
Thanks ~

Your best bet is to learn to do it manually.
Your next steps are
1) install recovery
2) flash superSU zip from recovery
Recovery is installed by fastboot.
In my signature, is a link to guides and info threads. Click it and then read the thread "adb and fastboot. What is it?"
This will tell you what you need.
Then you can download TWRP recovery image to flash.
Solved
It seems that my driver wasn't very compatible, and now my phone has been successfully unlocked. Thank you for the help.

Same here, none of the root explorers I tried seem to work.
Will the latest CF Auto Root wipe the storage on encrypted Nexus 5?

Try flashing pie patch. http://forum.xda-developers.com/goo...x-bypassing-pie-security-check-t2797731/page2 (post #13).
If problem still exists, try to install SELinuxModeChanger from the play store and change SELinux mode to permissive.
root
This is not a full root... at least in my nexus 5..
There are thing that I am not aloowed to do like disable startup apps and give some apps# permission

Some root apps aren't working on lollipop right now. Root explorer on es file manager is one of these

Search "amaze file manager" on the play store, it works flawlessly
Thanks, pie patch did the trick for me.
I had to use SELinux Mode Changer for viper though.
CF-Auto Root
Relocking the bootloader will not reset your warranty, for that you would have to run CWMbootunlocker script in twrp or cwm or philz. Oh and here is the link to a good thread to explain all that..

That is because of new SELinux polices which developers will need to workaround it ..
WARNING WARNING WARNING
You could use SELinux mode changer or run setenforce via term emulator and set it to permissive However!! this allows more malware to have access to your phone basiclly
Want to ROOT my N5, just root it, already unlocked bootloader.
Hi,
I just want to root my nexus 5. I am on Android 5.0, updated during the official rollout, and not using any custom flash/ROM.
Boot-loader is already unlocked, I had rooted it when on 4.4.4 Kitkat, but after I updated to Lollipop, all root priviledges were lost.
I do not want to flash any custom ROM or anything, just want to root it.
I found may threads and guides showing how to root is, but all of them included unlocking bootloader or flashing a custom ROM.
I dont even know what a custom ROM is and what is its use?!?! (noob)
Please just help me root my phone.
Thanks

A couple of options:
1. Flash CF-Auto-Root
2. Boot to TWRP recovery and flash SuperSU.zip
Everything is well explained in the main CFAR thread or in the General sticky threads.
Apply update to version 2.37?
Hi all,
I rooted my Nexus 5 running Lollipop some time before with CF-Auto-Root. I think Chainfire still used a patched kernel in this approach and installed SuperSU v2.20.
Afaik Chainfire managed to get root without the need for a patched kernel now. Therefore I would like to update to v2.37. Can I? How? Would the kernel stay patched after using the latest CF-Auto-Root? Do I need to go back to the stock kernel before applying the latest CF-Auto-Root? And how to go back to the stock kernel?
Thanks for your help!

Hi, I'm super new to this I have no clue what I'm doing, but I did manage to follow the instructions of http://forum.xda-developers.com/galaxy-tab-s/development/root-cf-autoroot-twrp-t800-t3079488 and get my t800 rooted.
Until problem occurs, at http://techbeasts.com/2015/05/01/root-twrp-recovery-galaxy-tab-s-84-running-lollipop-502/ step 9 "Once it has booted up, check out the SuperSu application in the app drawer. If it asks you to update SU binary, update it." When I open supersu app it only ask me to follow someone on google+ but didn't mention anything about update, couldn't find an update option anywhere in the app either.
I ignored this potential problem and then downloaded rootvalidator, everything was green only busy box was yellow and SELinux was blue saying something enforcing, I don't have a screenshot but these 2 were the only one that's not green. I installed busybox free and got busybox in rootvalidator green (from yellow). Not sure if the enforcing part was an issue so I left it like that.
So I use this guide to root t800 is to use xmod, and XMOD actually have their own tutorial on how to root and install and get it to work etc. just didn't have one for this model. I think I made a huge mistake of following their guide after this one, and got mislead not knowing wtf is going on..
I installed xmod and found out it isn't working, I installed kingroot from within xmod app and when I opened kingroot it shows my tab is already rooted. So I was sure it's not a rooting problem, I then found out xmod isn't working because SE is enforcing and I followed the video guide (from xmod faq) on how to make xmod work on enforcing device. I downloaded Link2SD and clear data+ unistalled xmod. But I also clear and unistalled kingroot (and kinguser i think?) and another app that came along with kingroot when i got it (It was in chinese)...
After this I lost root access and when I check rootvalidator it show my device is not rooted anymore. When {I click on supersu it asks me to update normal or from twrp/cwm...
Everything seem to be a mess so I'd like some advice is it better for me just to restore everything back to factory settings and root the device again? Sorry for this long and noob post I'd really appreciate if someone can help me out. Thank you so much!
Hi there
You'd be best served asking for help from the experts who own your device there in the device specific forum you already founded:
Galaxy Tab S Q&A, Help & Troubleshooting
[ROOT][RECOVERY] [ALL IN ONE] Cf-Autoroot-twrp-T800-T805-T-700-T705 [Tab S 10.5/8.4 ]
Good luck
So I had rooted my phone some time last year. Everything was fine until December 14 I woke up and my phone was updating on its own. This caused me to lose my root and now I want to re root it. If anybody can point me in the Right direction I would appreciate it so much. A game recently came out called Bleach: brave souls, and when I open it, it says an unauthorized program is running. Pretty much its reading that I have a rooted device, yet superuser is no longer on my device. I'd love to be able to play the game so I downloaded the "hide my root" app but as it stands, I don't have the root so it's pretty much useless until I root my phone. Again, if anybody can guide me through the process, if there is One for this update I'd be very appreciative. Thanks! If more information about the device is needed just ask me what you need and I'll do my best to help.

Hi
Thanks for using XDA Assist.
I don't believe any root methods work on the 5.1.1 update. There's a discussion about rooting the device here > Android Development and Hacking > Android Q&A, Help & Troubleshooting > [Q] LG G Vista - Root Request try posting your query there.
Good luck
