I can't root my OS12 ! - ONE Q&A, Help & Troubleshooting

And I have no idea why. Before I downloaded the newest update I upgraded my TWRP to the latest version. After the update I tried first to install SuperSU via google store but didnt work so i downloaded the installable zip and tried through TWRP. All I get is : E: failed to verify whole-file signature; E: signature verification failed.
Tried the old SuperSu that always worked (2.02) but I get the same bug.
I think the problem is that instead of TWRP when i start my phone with start button + vol down it gets into CYANOGEN recovery. I just installed TWRP ver 2.8.5.1 but its not working =/ dont know what to do, help please

You need to resinstall TWRP, just after you have done so, reboot back to TWRP instead of rebooting the whole system. Once back in TWRP you can flash SuperSU again, then reboot and you should be fine. Also make sure you have the cyanogen recovery option unticked under developer settings.

How do i reinstall TWRP? im pretty sure ive done it already but still when i turn on the phone I have the cyanogen recovery on, tried to do it with TWRP manager (at first i couldnt start it because but later it worked. However, when i click on "Reboot to Recovery" it does not work) I have recovery installed in TWRP manager (ver 2.8.6.0) maybe i can do sth with this ?
Edit: I was able to start TWRP manager, now I'm not again because it says "root is required for this app"

Once it flashes, are you rebooting back into recovery first (without switching off, fully rebooting, anything else)? You should boot into TWRP and then you can reboot fully, it should be fine. If you just reboot out of TWRP after flashing the it gets overwritten by the stock cyanogen recovery.
After completing the TWRP flash in ABD run the following command.
Code:
adb reboot recovery

Im doing what Im told, so - After the phone has booted back up, turn it off. Now to enter your newly installed custom recovery, hold volume down + power. The phone should boot into recovery mode.
Wish I wasnt so braindead on this field =/ and the cyanogen recovery welcomes me every time
okay so instead of fastboot reboot command i should write the one you gave me? gonna try
EDIT: ERROR, DEVICE NOT FOUND

yeah, i was doing it wrong but i did it right this time and it is still not working. Have my usb debugging on
Is it possible that after the update i dont have the bootloader anymore?

Okay. I tried and tried but failed. I have no idea what to do anymore. Downloaded new drivers for pc and new fastboot, tried like 15times to flash twrp on my phone and seemingly it worked but when I rebooted, turned it off and on again with volume - it's always cyanogen recovery there, never twrp. I downloaded twrp manager but it won't work because it requires root and I can't root because manager won't work. Saw on oneplus forum that some people have exact same problem but there S been no solution so far and I have no idea what to do anymore. The only thing I haven't tried yet is to hold start+volume- keys after I flash twrp and reboot the phone using the code, so instead of having to turn it off and on again maybe I ll be able to get into the twrp instantly and it won't get overwritten by cyanogen recovery.

OK so i am experiencing the EXACT same issues. When I go into Fastboot Mode all I get is a small cyanogen head forllowed by the words 'FASTBOOT MODE' I get no menu to navigate or anything.

After flashboot reboot do not let phone turn on again but use the start + volume- combination, it will take you to twrp. Found the solution finally but I still have some issues with graphics and Google account =/

[Q] [i9023] Blank/Black screen in recovery

Hey everyone,
Basically I was trying to flash a new ROM onto an old Nexus S of mine and when I tried to boot into recovery there was just a black screen. I pressed the power button and a single line saying "Clockwork mod Recovery" and the version number popped up. I assumed that the recovery must've been corrupted so I erased it and installed the latest version using fastboot which seemed to work fine.
Now whenever I try to boot into recovery I just get a blank screen with nothing else. I've tried using other recovery images such as twrp but the same problem happened, I just get the background wallpaper/image and nothing else.
I searched the forums and apparently people were having this issue earlier on when the i9023 was first released but now most custom recoveries are supposed to work with both i9020 and i9023.
Also the touch buttons light up and vibrate whenever I touch them when I'm in recovery mode.
Any help to this problem would be greatly appreciated as atm I have an old ROM which is buggy as hell and I need to get rid of it.
Cheers!
I had the same Issue. If you can boot into the rom, you can try to download the rommanager-app and install the recovery from there.
Hey I tried that already that and instead of booting into recovery it just went into the bootloader and said "No Recovery or Bootloader found".
Any other ideas?
Did you clicked the first point in rommanager? Install recovery, or you only hit the second button reboot into recovery?

Hey
I have the i9023 and I install rom manager. install CWM and if I reboot into recovery it works and I get in to CWM recovery.. but after reboot into os.. if I go into Rom manager and reboot to recovery it dont work? I just get the android figur and a "!".. then I just can Power + vol up and I'm in bootloader recovery..
Do I have to install CWM every time i want to use it? and can't I access CWM on boot op ?
sorry for my bad English
Normaly you have to flash the recovery only once.
Try to flash the newer clockwork-recovery with fastboot.
http://forum.xda-developers.com/showthread.php?t=988686
Alfiedk: You need to get rid of this file:
/system/etc/install-recovery.sh
As it re-installs the stock recovery every boot.
I think you can download any custom ROM for your phone, and flash it in CWM recovery, this will also solve the problem
Edit: Did you unlock the phone? Have you tried fastboot oem unlock?

what happens when you try to temporary boot into the recovery?
instead of "fastboot flash recovery recovery.img", try to "fastboot boot recovery.img"
Just look for an recovery.img that works temporary and then try to flash it permanently.
I'll try it and get back to you Xziped. If anyone else can think of any other ideas please just throw'em at me, I'm willing to try anything!
Yeah no help there either. It does the exact same thing temporarily booting into a recovery that it did when I actually had it installed on the phone :\.
I updated ROM manager to the latest and tried installing CWM with that but to no avail. It still says that there is no recovery installed when I do that.

Sorry but if not even the temporary recovery boots up, i dont know what else we can do
did you try some of the older recoverys? is your bootloader unlocked?
I haven't tried an older recovery and my bootloader is unlocked.
could it be a problem with my computer as opposed to the phone itself? As in my computer is messing up when trying to flash the recovery?
I've also noticed now that when I boot into fastboot mode the menu just locks up and doesn't respond to anything. Sometimes I have to pull the battery and other times it'll start responding after randomly pressing the power key a lot of times...
I'll try an older recovery next

[Q] Help! "no boot or recovery img"

I've been trying to flash a new rom, and I can't. Fastboot pops up every time I try to boot recovery saying "No boot or recovery image"
My phone still boots it's rom normally and can connect to the computer via usb just fine, but I've tried flashing several different CWM recoveries and none of them work, it all just gives this same error. I can't re-flash now, and this rom is not working well. What do I do?

are you spelling the name of the recovery correctly? is the recovery file(.img) in the same folder in your computer as fastboot is?
Search "flash image GUI" I think, here on xda, on the thread download the apk, then install on your phone, then go to rom manager the WEBSITE, find a recovery image that corresponds with your phone then download it. Now go to flash image gui and flash the CWR image you just got like 2 or 3 times just so it sticks now see if it works.
Nevermind, as simms said (didn't read properly). You can use the tab key to autofinish the name of the recovery.
Hi guys, I found the problem, but thank you all for your suggestions. the problem was my fastboot was still locked! (I'm not sure how I got this far without unlocking it, but now it's moot) Anyways, it works now, and all is well. Thanks!

Cyanogen Recovery problem

Really hope someone can help me on this. I clicked on update and now it shows 12.0-YNG1TAS17L
And when I boot the phone into recovery, it goes to a new screen of Cyanogen Recovery, it is totally different than TWRP that I have in on my phone.
I already make sure the phone "update Cyanogen Recovery" is unchecked. But no matter now many times I reboot, reset the phone. It goes to that new recovery screen.
Now I can't root my phone at all. I tried android-sdk-windows.....etc. It will not work.
Tried install it from recovery, it saids install failed.
IS there a way I can use TWRP instead?
Thanks

Use fastboot or a toolkit to reinstall TWRP, after it installs reboot back into TWRP, dont reboot the whole system and TWRP will stick. Otherwise TWRP will be overwritten with the stock recovery.

Bro, I followed this instructions. Did everything I could but still boot up with stock recovery. It is stuck. I don't know what to do .
As you can see the screen shot when I tried push the superSu to it, it saids error: device not found.
All previous steps I followed without error.
But end up still showing stock recovery.

You haven't followed the instructions there, from what I can see you've issued the "fastboot reboot" command after flashing the recovery, which you're not meant to do, you're meant to force a reboot directly into recovery with the power + volume down combo.
Hi Heisenberg, I got the problem solved by using the toolkit. Now I got my TWRP back and rooted. Thanks for the info.

TWRP just won't install. EVEN when I do the "no fastboot reboot"

EDIT: IT FINALLY WORKED! I just flashed an older version of twrp. Pretty weird how that's working and the newer one isn't. Should I keep this post for people with the same problem?
I know about the problem with cm12s and with the cm recovery thing.
I tried everything. Searched and tried nearly all of the different recovery or root install tutorials. But it's still not working!
Every time I install a recovery (both twrp and cwm) it won't install even though it said it worked. When I do the "remove usb, vol down + power" trick after flashing it just won't boot. It just shows the logo and then it reboots. If I release everything it boots my phone up normally. Even clicking recovery reboot in the reboot menu doesn't work. Then it will bring me to the cyanogen recovery.
My debugging mode is on.
Cyanogen recovery update is OFF.
I'm now using cm12.1s but it didn't work on cm12s either.
ADB and Fastboot are working fine. I tested it and my phone reacts when I give it commands (like fastboot reboot or adb devices)
My bootloader is unlocked (confirmed with fastboot oem device-info)
I just got this phone yesterday. I didn't expect this much trouble with just rooting.
ps: this is one of those "it should work, but it doesn't" moments.
Yes. After cm12 the cyanogenmod is ignoring the cyanogen off recovery mark.
After flashing recovery twrp via fastboot, direct reboot to recovery manually via button. Try look at faq. See q22. http://forum.xda-developers.com/oneplus-one/help/faq-oneplus-one-frequently-questions-t2895136
Always keep a post like this, it's good for future reference (people having the same question will thank you for sure)!
Use Philz recovery. Many are facing same issues with TWRP

Hi Benalimarwan,
Thanks for your post. I flashed openrecovery-twrp-2.8.5.0-bacon.img. but, it still didn't work. When I logged into recovery mode it still logged into cynogen recovery. Which version of twrp did you flash? Thanks!

Works for me from latest stable CM12
1. Unlocking Bootloader via fastboot
fastboot oem unlock
fastboot reboot
2. USB Debugging -
On your phone go to Settings > About phone > Tap on Build number 7 times. This will enable Developer options. Now go back to Settings > Developer options > Enable USB debugging
3. Disable CM Recovery Protection -
On your phone go to Settings > Developer options. Then disable the 'Update recovery with system updates' option.
4. Installing a Custom Recovery
fastboot flash recovery openrecovery-twrp-2.8.5.1-bacon.img
got it from http://techerrata.com/browse/twrp2/bacon (one recommends don't use 2.8.7)
reboot to system
5. Flash your custom recovery again, but after flashing don't do a normal reboot. (DONT FORGOT TO Disable CM Recovery Protection first in normal boot before)
After the flash has succeeded disconnect the usb cable, then power down the phone by holding the power button down, once it's powered off use the power + volume down button combo to boot directly into recovery. This first forced reboot into recovery somehow subverts what was keeping it from staying flashed and all subsequent normal reboots into recovery will boot into the custom recovery of your choice.
gawd i nearly went out of my mind last night trying to flash TWRP , everything was working fine , fastboot checked out , unlocked the OEM also but it refused to flash TWRP , threw up errors "cannot open recovery' then i remembered the "hide file extensions for known file types" in win7 which was checked and ran
fastboot flash recovery rec[TAB]
Click to expand...
Click to collapse
.i.e hit tab button before hitting enter and it flashed it like a charm !! and i was already to throw this new cell out of my window
Please help me understand Step 5.
Once 'fastboot flash recovery openrecovery-twrp-2.8.5.1-bacon.img' is completed, I shouldn't do a 'fastboot reboot'. Instead of that disconnect USB, and then Poweroff using power button. Now use Power + Volume down to boot into recovery. This should allow me to use twrp recovery. Is my understanding correct?
Regards,
Kiran
Hi Guys,
Just did step 5 again.
Did 'fastboot flash recovery openrecovery-twrp-2.8.5.1-bacon.img' and disconnected USB, Powered off the device and powered it on using Volume down + Power button. It logged into twrp recovery. I then selected 'Install' and phone automatically got rebooted. Not sure why. I powered it off and powered on again using volume down + Power buttons. It then logged into CM recovery.
Repeated above step again. Again faced same issue. Any ideas?
I unlocked boot loader 4/5 days back. Since twrp recovery was not working, I continued using phone. Installed several apps. Do you think this might be an issue? Do I have to unlock boot loader again and then do 'fastboot flash recovery openrecovery-twrp-2.8.5.1-bacon.img'??? Please suggest
Regards,
Kiran
Do it this way with fastboot:
fastboot flash recovery recovery.img (you know the drill...)
when this is completed type in fastboot reboot
BUT MOST IMPORTANT! hold the volume down button on your opo the whole time before you press enter to run the command and keep holding it until TWRP boots up.
This worked on 5 OPO's. (3 were mine, one was my brother's and one is a friend's)
im too on stock 12.1..So which twrp recovery version ll i flash????

Wug's Bacon Root Toolkit
I had this problem when I tried flashing the custom recovery (TWRP) manually. It didn't matter what I tried, I could never manage to make TWRP persist over CM Recovery after a reboot. After giving up and staying in stock for some time, I decided to try again after getting the OTA to CM 12.1S, but, as no surprise, the same thing still happened. So, as a last try, I downloaded Wug's Bacon Root Toolkit and voila... it finally worked, I had a TWRP that persisted over CM Recovery after a reboot. I don't know what the toolkit did different than me when I did it manually, but it managed to make it work! Hopefully it also works for you...
only used toolkit for Fastboot driver installation...Good step by step instructions...but flashed 2.8.7.0 twrp with adb commands as described by Heisenberb...finally installed recovery n rooted my opo...

AcmE85, Your suggestion worked like a charm bro. Finally was able to fix the issue. Thanks much for your help!

My OPO won't let me boot into recovery!

I have a huge problem. After having a lot of issues rooting my device, I downgraded to COS11s and was finally able to root and install TWRP.
After that I tried to install Sultan's latest build, which failed. I then installed the latest CM12.1 Nightly (which is what he recommends if the installtion failes) and right after that his build, which worked - finally. I installed Gapps and rebooted.
I noticed I hadn't installed supersu and wanted to reboot to recovery to do so - but now it just won't boot into recovery! My phone turns on and boots straight to the lockscreen. I tried the button combination, the advanced reboot menu - everything. It just won't boot into recovery. I even reinstalled the recovery via fastboot (which supposedily was successful), but the problem remains.
Flashify doesn't even show an installed recovery!
HELP!

I noticed I hadn't installed supersu and wanted to reboot to recovery to do so - but now it just won't boot into recovery! My phone turns on and boots straight to the lockscreen. I tried the button combination, the advanced reboot menu - everything. It just won't boot into recovery. I even reinstalled the recovery via fastboot (which supposedily was successful), but the problem remains.
Flashify doesn't even show an installed recovery!
HELP!

Tried using adb yet? If you haven't, give it a try. If you don't have it set up, you can find several threads on how to do it, from full installs to small zip files. Considering you have fastboot working I assume abd also. Make sure USB debugging is on, plug your phone up and allow USB debugging when the prompt is displayed on your phone. Then adb reboot recovery.
Not familiar with what build you are on, some require you to enable root access mode from developer options, might check that also.

Thanks for you answer. I have adb set up. USB debugging is on. I will try adb reboot recovery. The weird thing is, it doesn't even boot into stock recovery (My first thought was that the phone replaced twrp with CM recovery somehow).
That's a good point, I will turn on root access and try again.

Another option, if nothing else seems to work is start over. I generally use nexus devices and flash factory images, looks like you can do that also on the one..
Hello,
I have the same problem. I unlocked my OPO, flashed the TWRP 2.8.7.0 and everything went good and smooth. Then I flashed CM12.1 and it worked. Now I wanted to downgrade TWRP to the TWRP 2.8.6.0 because of some issues with the latest version and after flashing the older version it will not boot to recovery at all...
Please help.
Thank you
EDIT: SOLVED!!
Okay, so I managed to get it back working again.
How I proceded:
1. http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541 and do everything that is said in the 3rd point of the first OP post. (+download the file for your OPO - either for 16GB or 64GB model - after you have it downloaded unpack it)
2. flash all the files listed in the 3rd point of the first OP post
3. boot in the OS, enable developer settings and enable USB debugging and allow it
4. get back in the fastboot mode and flash either TWRP 2.8.6.1 or later versions (because of Lollipop compatibility)
5. enjoy!
God bless you.
