[Q] lost root access

Hi, forgive me if this is a stupid question but after flashing the latest t0lte nightly I have lost root access.
How has this happened?
I've been flashing CM nightlies for weeks but fancied a change after reading up about omnirom.
Im running an international note 2 LTE using cwm, rooted with Odin.
How do I get root access back? Is it case of me having to flash via Odin again?
More than grateful for any help here!
Cheers

Flash SuperSU in recovery
We haven't yet integrated SuperSU into the package itself, and fixing that has been low priority since:
1) You can't flash Omni without a custom recovery
2) If you have a custom recovery that can flash Omni, you can flash SuperSU in recovery
3) Once you've flashed SuperSU, you can go to its Settings->Custom ROM and enable the backup script

Ok, i've pulled the superSU zip from chainfire and flashed it, however it is giving me a error message.
"There is no SU binary installed and superuser cannot install it. This is a problem!"
So I am unable to run step 3
Please help :crying:

N910F Stuck in boot sequence - HELP PLEASE!!!

Hi Guys, I came on here last week seeking advice as my Note4 has always been seriously laggy and slow. I tried resetting to factory etc however still the same. So the advice I got was to root and try another rom.
I successfully rooted my 910F device (confirmed by running test root app). I then downloaded a new rom to try out. In the instructions it suggested that I should be running the respective versions of Bootloader and Modem - which I downloaded from the links in the instructions. I installed both Bootloader and Modem via Odin successfully however now the device just loops in a boot up sequence. I copied the ROM files to the SD card however the when I try and load the rom from there it says that 'Update from external storage is disabled'.
I've downloaded a few other ROMs however they are zip files and I am guessing not designed to work with odin??
Hoping that there is a headache free way of recovering this.
Apologies in advance. I am an newbie with this stuff, really appreciate any help!!!!!
Thanks,
OB

You need custom recovery use TWRP.
Rom needs to be a zip DO NOT UNZIP IT.
From recovery flash the zip.

Really appreciate the reply.
The modem and Bootloader have already been loaded. So to be totally clear, I need to download an app called TWRP and load the ROM file (ZIP) with that right?
Thanks a bunch, really appreciate the help.
Bests,
OB

To add, the phone is not booting up (stuck in the boot up sequence) so I cant download and install any apps on it? Is TWRP a PC app?
Thanks,
OB

Nope, TWRP is not an App. It's a Recovery. You will find it in the development section. It's an img which you flash via ODIN. After that, you shut down the Phone and reboot via holding vol up + Home + Power. It will Boot you into the TWRP Recovery. from there you can then Install the Roms. They are provided as Zip. Don't Unzip them. Just select the zip to be installed via TWRP.

Got stuck trying to root, just want to return to stock/factory settings.

I'm new so please forgive me and my ignorance through all of this. I had a great root experience with my old LG G3, so when I got my Axon 7 (A2017U) I thought I'd try to root it too. I tried to follow DrakenFX's guide (http://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204) but I bit off more than I could chew. I got to the point where I had TWRP up, but this is where I think things started to fall apart. I was confused by the instructions and in a haste I continued anyway. In TWRP I went to Wipe>Format Data typed in yes like TWRP said and boom, I had no idea what happened. Rebooting only got a screen that said "Type in your password" but my passcode I had on the phone before it bricked didn't work. So by now I start panicking a bit. I thought I made a mistake earlier so I went back and tried to reinstall TWRP by putting the phone into EDL. The phone got stuck that way for a while, but I now I have it in TWRP. Right now, I just want to get back to safe stock android.
I'm 200% sure I messed with something I wasn't supposed to and I believe that is the system image(?)which Draken also linked (http://forum.xda-developers.com/showpost.php?p=68248798&postcount=53). I'm downloading it as I type. I'm going to do my best to leave my phone just like it is right now, in TWRP, and wait for more advice on this before I do anything else.. What I'm curious about is where did I go wrong and what do I need to do to get my phone working again, preferably without returning it? Thank you for any advice you have to offer.
Update: It's worth noting I didn't know to enable OEM Unlocking when I was in stock android. Dumb move I know. I'm new here.

I tried, but the downloads take extremely long and are unreliable for me. I was downloading the stock system file at around 14 kbps and it eventually failed. Any other suggestions?

I've done the wipes multiple times. It's mostly the downloads I'm having trouble with. How and where do you get them? The links I found were dead or had a slow speed.

Did you save the recovery backup? If you did then use the axon7root.exe to flash the stock recovery. Then download the stock B20 from ZTE.

I've been able to find some recovery images that I found on other threads. The thing is, when I try to flash them on TWRP, I get an error about "/dev/block/sde14" being read-only.

no no no no ..................... put phone in EDL mode. Copy the stock image into the folder with the axon7root.exe file you used to flash TWRP. Make sure the stock file is named recovery.img (or whatever the TWRP file is named in that folder, it has been a long time since I did this). Then use the axon7root.exe program the exact same way you did before. It will flash the stock recovery. Then in stock recovery you can flash the B20 from ZTE

ok - download it from zte. Put it on your SD card. In recovery select update from SD card. Be warned it will work but it is slow. Also note that while I will not say the bootloader unlock doesn't work on B29, I can say it worked flawlessly on B20. If you want unlocked I recommend doing so on B20.

I tried that. It won't accept the zip file and it's unclear which file to sideload. Would you happen to know? This is what files are in the unpacked zip. https://gyazo.com/c7546c3ed0dcb0972653eaeba42fcb40

Maybe - I'd have to download it to find out. If you can't get stock recovery to take it this post http://forum.xda-developers.com/showpost.php?p=69434328&postcount=17 gives you instructions on what lines to remove from the updater-script to make it flash in TWRP (I didn't have a problem making the stock B20 go in stock recovery, but I was unlocked at the time). You could reflash TWRP and try that.
Or just try this in TWRP http://forum.xda-developers.com/showpost.php?p=68873482&postcount=2

I'm going to try the first option. The second option's link take horrendously long to download.
Update: Trying to flash from TWRP results in error "Could not find 'META-INF/com/google/android/update-binary' which makes no sense since update binary is exactly where it should be.
Further Update: It seems that the problem might have been that when I compressed "update.zip" to fix "updater-script" it changed to file path by adding the title of the folder "update" to the beginning. I think that messed with the path giving the the meta-inf error.

Can't root OnePlus 2

I've unlocked my bootloader and installed twrp, but when I want to flash the superSu zip, my device stucks in booting (bootloop). Is there any fix for that.

Hello.
Have you got a conflicting app? Possibly. If so try systemless?
Are you flashing official latest? Is your twrp the latest as well. Have you tried installing the app and seeing if it do it that way?
---------- Post added at 06:09 PM ---------- Previous post was at 06:07 PM ----------
Also not to call you a lier or daft. Are you sure! You've unlocked, have you gone into settings, unlocked oem ticked from there?
Im sorry I'm just covering all bases .

Please be more clear. What version of TWRP is flashed. What ROM are you currently on? also what version of SuperSu did you flash?

So, I just found special modified zips for the One Plus 2 and it worked fine with them. I don't know what was wrong with the Orginal files, but I don't care.

Nexus 4- Yes bit archiac

Hi
Nexus 4 is going in continous boot loop, this was post the 4.2 upgrade. the bootloader is showing the sleep driod with the red triangle, something is broken.
have tried to install the older version of image but , the moment it goes on line , it says upgrade ready.
how can i do a clean start or is some hard ware broken??
please help , want to keep this beauty going .....

Download the stock lollipop image from google for nexus 4 codename mako. Read all the flashing instructions along with it. It usually contains a flashall.bat, so u won't have to manually flash everything.

What happened exactly? Flashing error, bootloop? A little detail would make it easier for people to help.
Try flashing using nexustoolkit if adb didn't work for you. Bte lollipop takes a long time to boot for the first time so just wait.
