installed CM12 and lost root and recovery - ONE Q&A, Help & Troubleshooting

Hi chaps, yesterday I had an update (CM12) on my rooted OPO and after having done the update I lost root (which I knew I would have anyway) but, surprisingly I also lost TWRP, which is rather unusual. So now, my question is, do I have to go through the whole rooting procedure again as detailed here http://forum.xda-developers.com/showthread.php?t=2788632 (procedure which, incidentally, I followed the first time I rooted my phone last year) or if not, what should I do? What steps should I skip?
thanks

See this thread, someone with a similar problem, pretty easy to sort if you're near a PC. Just remember to boot back into recovery, before rebooting fully and also turn off the 'update cyanogen recovery' option under developer options.

Thanks mate, had a very quick look, so essentially the answer is yes, I have to go through the whole procedure again and do it either through the procedure in the first link or in the second (with the toolkit)
thanks

You just need to flash a custom recovery via fastboot or using a PC tool. You can then flash a superSU zip to get root.

Cool thanks. OK so I don't need to unlock the bootloader, I can just go to step 2 in here http://forum.xda-developers.com/showthread.php?t=2788632

Your bootloader is still unlocked, so no need to do that again.

Ah brilliant, thanks for clarifying that!

[Q] Please Help! Phone Bricked (Noob Problems)

Hey all, sorry if this seems like other questions being posted, but I can not get my phone to work even after attempting the other fixes posted on the forums. I rooted my phone and was running the stock rom that came preloaded with it. I attempted to install CM10 through Rom Manager to no success, so I then tried to manually flash it as well as Gapps. My phone initially got stuck at the CM10 bootloader, but i could still go into CWM Recovery 5.8.3.1. After trying to get the rom to work more, it seems as if all I can access is CWM Recovery and nothing else. My phone wont even boot into the bootloader anymore and all i have access to is CWM Recovery.
I am not the most tech savvy individual when it comes to this since it has been ages since i tinkered with roms, but I would really like to fix this. So heres the facts since my post is so long (sorry!):
-Phone WILL NOT go into bootloader
-Can ONLY ACCESS ClockworkMod Recovery (5.8.3.1)
-SD Card wont mount (I get error "E:Unable to open ums lunfile (No such file or directory)")
I really just want to go back to stock and root again from scratch to reduce any errors like this from occurring in the future and ANY help would be appreciated because I am totally lost and without a phone now. To make things even more difficult, I only have access to a Mac running Lion....although i do have Windows 8 through the use of a bootcamp program, so I CAN run windows programs. Thank you all for any information you may have!

Well since you in bootloader flash TWRP and then boot.img and then reflash the rom just to make sure.

Sorry. Best would be the All-In-One Toolkit, TWRP is a recovery to replace CWM because its that what's messing you up and also TWRP is better. Toolkit will also flash the boot.img too.

Okay, will do! Also, where would I find the Boot.img?
And on a side note; my phone says S-ON...I thought when rooted it was supposed to be S-OFF. Could that be causing problems as well?

Boot.img is in the rom zip. S-On is not the reason its CWM thats messing you up with getting into the bootloader but also not flashing boot.img is not helping too.

Np but this time use TWRP as your recovery and once you up and running with CM10 you can use Flash Image GUI to flash the boot.img if you ever update the rom.

[Q] Unlocking problems for the bootloader

I am trying to unlock my photons Q bootloader on the Motosite which is well known. I check it now a million times if I have a typo and I Dont.
The button with the "request unlock key " comes up, I hit it, and didnt recieve any mail. And I started last week doing it.
The Photon q has a GSM mod done by the almighty CornholioGSM, and I am using a connection from Germany. Since it is a Sprint photon, I thought that it might be discarded, because the ip it comes from is german ?..
Would be great to have someone telling me if there is another solution to this ..
I tried to flash with the locked bootloader the recovery, but get the message "invalid image size" on CWM or TWR.
I hope this Q is not too noob for all of you.
I would try motochopper or whatever the exploit was to unlock without Moto's assistance.
It may have been unlocked previously, (relocked for warranty swap) in which case I'm not sure you can use the site to re-unlock the device...

First of all thank your for your answer ! Most likely you are right. Now my Q, I did read Motochopper just install SU and also gives root, but without touching the bootloader. Dont I need to unlock the bootloader if I want to install Cyanogen or any other Mod ? Maybe I understood that wrong.

If you're wanting to install TWRP, I think they have a new app now... TWRP Manager?
I've always installed recovery using fastboot on the Q, so I'm not very familiar with the apps .

I tried the TWRP Manager, the manager shows me success for installing the TWRP recovery, but I cant access it. It switches back into Fastboot telling me flash failure. Actually I would like to install CM11. Well I will try to install the latest nightly and see whats happening. Hopefully it doesnt brick. :silly: Thanks for your help, I will let you know about success or fail.

You need to install some sort of custom recovery in order to flash a custom ROM.
Open Recovery or TWRP are both fine. CWM is really old for our device, I can't recommend it.

So yesterday Motorola send me the messages with the codes which I apllied for almost 2 weeks ago... I guess the next days will arrive more.
Ofc I tried to unlock and it worked as expected. Now with fastboot flashing tto recovery 2.8.0.1 of TWRP went flawless. Actually I am really impressed how easy it worked, unlike using all the other tools like motochopper and TWRP Manager, which actually didnt solve the problem at all not having a unlocked bootloader.
Now my last Q: Which CM11 is the preferable choice for using it with the Photon. I dont care so much about Nightly or not. What I need is stable VPN and WIFI, and working mail and messenger like Cypher.
And! Thank you so much arrrghhh for all your advice and help. This forum and its users are really a great help to the community of android !
All DONE
Ok used TWRP 2.8.0.1 to install cm-11-20141012-NIGHTLY-moto_msm8960_jbbl and the PA-Gapps-Modular for 4.4.x. Great work on everyone who participated making this possible and developing the necessary tools.
Thanks again to Arrrghhh and Cornholio !

Confused - A checklist.

So, this is my first time flashing an Android device. I've been reading and searching for two days and I think I have most things in order. Let me check this is what I need to do and in the correct order to flash Cyanogenomod Marshmallow.
Unlock bootloader. (Haven't found a guide for this yet)
Flash latest TWRP (I'm guessing this will be done with Odin?)
Then I can proceed to copy my images and wipe/install them as per the guide.
This place is extremely confusing. There are guides left and right for everything under the sun and figuring out which I'm supposed to be using is a minefield. I just wanted to check I'm on the right path here as my head is getting a little cabbaged with it all.
Thanks!

You're a star pal. I'm already on Jellybean so I assume I can skip that part? And that recovery is exactly the file I downloaded earlier, so it's good to know I was on the right track! I'm struggling for how I actually install the recovery though?
Your assistance has been very appreciated mate.

Detailed step by step instructions here that should be the same way, just put the newer recovery .md5 file :good:
this is one of my very detailed guide that has all my knowledge compiled about our device that you may find useful. it's a bit lengthy but should be a good read.
Absolutely throwing me here. Installing the latest TWRP doesn't seen to alter anything at all. Everything goes through fine. The only thing I can wonder is in the guide you linked it says "Make sure Re-Partition & F. Reset Time are unchecked" but the images with the guide always have F.Reset ticket. Should it be ticked?
I am right in thinking TWRP should show a new custom menu when I boot to recovery aren't I?
Your guide is an excellent reference point btw. This is great for me starting out, thank you.

[Solution/Solved] Pixel Bootloop After Rooting Chainfire/Flashing boot-to-root.img

I stupidly tried to use Chainfires root method on my pixel by flashing boot-to-root.img. I am now stuck in a bootloop and I have no idea how to fix it. I can get into the fastboot page I think it is called by holding the volume down and power buttom. How can I fix this? Sorry if it is a dumb question. I tried using adb but don't know how it works and I get the error 'error: device '(null)' not found' when trying to do 'adb reboot bootloader'.
I really appreciate if anyone can help me. I am freaking out :laugh:

Try downloading the stock image and installing that from fastboot. If you are on a Verizon one and on 7.1.1 you are out of luck for root if you bootloader isn't unlocked.

Ok, stop freaking, this is very fixable. Assuming you have the Google version, or the Verizon version unlocked.
Short answer, we are going to get it into fastboot mode and we are going to flash you back to stock and probably save your data.
First, we need to make sure you have the correct version of Fastboot/ADB. It must be from GOOGLE.
https://developer.android.com/studio/releases/platform-tools.html
Unzip that onto a spot on your desktop.
Then go here and download the latest image for the Pixel. I am assuming you are in the US, get 7.1.1 (NOF26V, Feb 2017) for the Pixel.
https://developers.google.com/android/images#sailfish
Unzip that into a the Platform folder you made above with the fastboot tools. When you are all done it should look like the picture below. The highlighted items are the items that came from the Factory Image you extracted in step two. Everything else is from the platform tools.
Now RIGHT click 'flash-all.bat' and edit it. Near the end...look for the -w and take it out and save it. Removing that is what is going to save your data.
Power down your phone, restart it in bootloader mode. Power and Vol Down. Connect it to your computer and then double click 'flash-all.bat'.
That will take you back to stock unlocked and all your data and settings will be there.
Get past that and let us know. Then we will get you properly rooted. Yea, you used the wrong root process.
I love you <3
Thank you so much. I stupidly was trying to flash a file that wasn't an image file! I really appreciate your help man I don't know what I'd do if it wasn't for you.

No link handy, but here is how I do it. And yes, it is via fastboot, only way I know of at this point.
Download 2.7.9 SR3 SuperUser and copy it to your phone.
https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
Download TWRP RC1 and copy it to your fastboot folder.
https://forum.xda-developers.com/pixel-xl/development/twrp-alpha1-pixel-devices-t3500312
Using other versions than above will bootloop you. Reboot the phone into bootloader mode. Power and Vol down.
fastboot BOOT twrpFilename.img Where twrpfilename.img is the name of the TWRP file you just downloaded. Note is says boot in the command, not flash.
That will boot the phone into TWRP. Select Install and install the SU zip you copied to the phone above. And reboot the phone, done.
Thanks! That worked.

If it is a Verizon phone, no you can't unlock it. If it is a Google phone to unlock...below is a decent link on how to. Except use the ADB Fastboot tools I link to in the third post of this thread.

And be aware, when you unlock it...it will wipe all the data on your phone.
My pixel (stock, not rooted) is boot looping after the May OTA updates. Google support says to take it back to the store as it's still under warranty. Would the above fix work for my phone? Is it worth it, or should I just get a new one? This is already my second pixel as the first one died abruptly after 3 months.

Is the bootloader unlocked? If so I would certainly try flashing stock first. It can't hurt, and moments ago my Nexus 6 that I keep for backup was doing the same thing after the OTA. I just reflashed stock and it is fine now.

I think so, but am not 100% sure. Was bought unlocked from a retail shop. (Sorry, am a bit of a newb!)
So please let me understand
I am on 7.1.2 april (N2G47E), and if I want to update to may N2G47O the steps are:
- sideload ota
- flash new bootloader from may factory image
- twrp RC1 and supersu 2.79 sr3
Does this work or do I have to make something different?

Unlock bootloader then rooting method?

Hey everyone, I've been lurking around for about two months, from when I picked up this phone. It's still completely stock. Unrooted, S-ON, all that. Well, after the update to Nougat, I've been searching for a way to unlock the bootloader & root. Is it safe for me to use WinDroid Toolkit for the process? Just need a guide for the process, for the most part. I appreciate any help that anyone is willing to offer.

Go to http://htcdev.com and make an account, then follow the steps and unlock your bootloader from there. After that you fastboot flash TWRP using ADB, and then use TWRP to flash a root solution. I prefer Magisk.
Alright, just unlocked the bootloader, going through the process of setting up my phone once again. Do you have a link to the Magisk & TWRP programs that I can use? Also, should I put the TWRP file in the same folder as the fastboot files?
I greatly appreciate the assistance you've given me so far, I'm deeply grateful man.
Okay, so I flashed twrp, then the seSuperuser zip that was linked to in CaptainThrowback's thread. Now my phone is stuck in a bootloop, it won't go past the HTC logo with the red warning letters. What do I do now?

try this step by step.. :good:
1.Flash TWRP 3.0.3-8 via Fastboot.. Do not reboot into system, enter into recovery..
2.Do a factory Reset via TWRP.. Do not reboot into system
3.Now flash SuperSU 2.79 SR3.. Reboot into system..
couple of bootloops are common, do not give up for at least 3 bootloops..
It will take a long time to boot as you have done a factory reset..
So be patient and wait for at least half hour..

Sorry about this - I updated the TWRP thread with the current/preferred root method: MagiskSU.
You need to flash a stock boot.img and then flash the Magisk zip from the linked thread.

Aw crap, I wish I would have seen this yesterday. I tried to format data & flash one of the stock rooted roms for marshmallow roms for my sprint one a9... now it just hangs at the HTC One logo. I'm gonna assume that I'm screwed until a stock rooted Nougat rom is released for sprint.

Can't you just flash the Nougat RUU?

I found the post about the Nougat RUU, but the program won't recognize my phone cause it won't boot. I'm gonna try & flash the firmware through TWRP.

You don't flash firmware with TWRP. But you can use the SD card method to flash the RUU, which doesn't require a computer.

Sorry to bother you again, but you wouldn't happen to know a method of extracting the rom.zip from the exe file, would you?

Thank you so much, man. The zip is prepped, just gotta charge my phone again to 30%. But afterwards, will I have to go through the unlock bootloader process? If I do, I don't wanna mess up on the rooting process.

Your bootloader will stay unlocked.

Awesome, I appreciate all of the help, man. Sorry again if I annoyed you with all of my incessant questions. Just didn't wanna mess up my phone even further.
Hello Guys,
I Have an HTC one a9 with 7.0, s-off, bootloader locked
I have some concerns before I root my phone
If I unlock the bootloader and root the phone, Will I have the option of phone encryption as it used to be ?
If I unlock the bootloader with HTCDev and flash the TWRP with SuperSu and boot file, it is a MUST to do a data factory reset? or I`m able to do all the process without loosing my data?
Thank you in advance

Unlocking your bootloader will wipe the device.
Hi all, I've been lurking and reading for 2 months, preparing to root my device. So this title fits my mood.
One A9, "factory unlocked version", S-on, running 1.57.617.60
Just did the actual unlock from htcdev so now data is erased. I'm re-reading the threads I saved to prepare, now that it's time to actually finalize what ROM I want to run, but now have a few questions before completing the plunge.
In past threads I read the newer MM and N security prevented rooting, and reverting to Lollipop was necessary. From what I read here that is no longer the case?
If I want to debloat the system I am already running, can I do that without finding a custom ROM to run?
Thank you

Yes, you can root and debloat Nougat. Though you should make a stock system image backup first of you ever want to receive an OTA again. The TWRP thread FAQ has a lot of information about this.
