I am trying to flash my N4 with cyanogenmod following the official wiki.
I'm at the point where I've installed TWRP into recovery, I've wiped everything (I've even formatted them since I couldn't wipe all of it initially), and the only error I see is "unable to mount /usb-otg".
Then, I've "installed" the CN zip files for the 13 and 12 versions, none of them works in the sense that when I reboot the system, I'm always coming back to TWRP.
What's wrong? Any suggestion?
Thanks
I've the same problems with my nexus 4

Hi gerardgerard,
I also wanted to flash my Nexus 4 with Cyanogenmod 12.1. So I installed TWRP into recovery and wiped everything, like it's explained in the wiki. I can also see the error "unable to mount /usb-otg". When I want to reboot the system I always get back to TWRP. Cyanogenmod doesn't boot correctly. Did you find a solution for the problem?
same problem
Hi
I'm having the same problem. As follows:
Cause (my mistake): I have been using Cyanogen-mod nightlies for a couple of months on my Nexus 4, and made the grave mistake of leaving the phone to upgrade one night but without it being plugged in properly - and it ran out of power part way through! (At least, that's what I think happened).
Fortunately, it would boot into bootloader and I could use adb/fastboot. I (re)installed TWRP 2.8.7.0 (from my Mac, using fastboot). And that works fine - I can boot into twrp ok.
Next I loaded the latest nightly from cm (using fastboot - is this what people call sideloading?) and used twrp to install it. It goes through the installation fine (the only error message is that it can't mount /usb-otg). But when I reboot it just goes back to twrp.
I then tried installing the earlier cm nightly that I know worked, but with the same result.
Finally, before I first installed cm I did a backup (using twrp), and I have tried recovering that. It seems to do all the right things, but again when I reboot it just goes back to twrp.
Any suggestions would be welcome.
Thanks

Flash back to a completely stock ROM and run through the set up to make sure everything works. Then copy CM to the phone, reboot to fastboot, flash twrp, immediately boot into recovery using the volume and power button without leaving fastboot, wipe data, cache, system, flash CM, reboot.
If the phone will not boot after flashing a stock ROM, boot to fastboot, flash the userdata.img file, and immediately go to stock recovery without leaving fastboot, wipe data/cache, reboot.
It works now!
I managed to fix the problem ... I found this guide for the Nexus 5:
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
and I applied those instructions. It didn't work first time, so I just repeated them and now it's working. I used the 5.1.1 stock downloaded from https://developers.google.com/android/nexus/images#occam.
I guess this is what audit13 means in their post - so thanks are due there.
I will next reinstall twrp and cm and I don't expect any problems with that (having done it successfully before).

Hi all,
I was running the official Google 5.1.1 version until this morning. I now did an oem unlock using fastboot and installed the latest twrp recovery 3.0.0, and finally copied overy CM-13 nightly (and Chroma-2016-02 for testing purposes) using adb.
Flashing itself work flawless, there is no warning or error message, but when hitting "Reboot" within twrp the Google logo shows up for a few seconds and it directly boots into twrp again. This is with both, CM-13 and the latest Chroma.
So I basically cannot get my Nexus-4 bootet regulary any more.
Any ideas what the problem might be?
Any help is welcome,
regards, mistersixt.
Mmmh, strange, I did a factory installation (latest 5.1.1 from Google) and started the same thing from scratch ... and guess what... the system is booting fine now.
No idea why it did not work on my first attempt .

Same here. Running stock until today, wanted to see a different ROM, flashed TWRP 3.0.0, it refused to boot anything else. Tried to flash DU, then tried Chroma. Did a full wipe, then an advanced wipe selecting everything, then a full format, same thing. Installed TWRP 2.8.7, same thing. Finally installed latest stock, it is now booting, optimizing apps. I don't know if installing a custom rom will work or not yet.
Edit: Yeap, after flashing stock 5.1.1 and installing TWRP 3 again, the phone is now booting into DU.
First time I did a wipe with TWRP, it complained that it couldn't mount /data. Since this is the first time doing it, I assumed it was normal. After going through a full format, it didn't complain about data anymore, but it did complain about something to do with /dev/zero and another file under /dev/. I assume it was trying to dd /dev/zero to a file under /dev/ that didn't exist.

Done the whole process from scratch again and worked like a charm
Hello, same story here.
First I:
- unlocked bootloader
- flashed TWRP (last version)
- flashed Chroma and Gapps
- reboot
=> I consistently rebooted on TWRP. No way to properly install the ROM. No error message at all.
Then I found this thread, and did as described:
- flashed the latest stock ROM
- flashed TWRP again (took me ages to manage to do this: TWRP would not install. I don't know how I finally did it, but at some point it suddenly worked. Probably a driver problem)
- flashed Chroma and Gapps again
Bingo, this time it worked! I don't know why it didn't work the first time. Could it be linked to the bootloader unlock thing?
Hi,
So I have created this thread just because I can see many people creating new threads as after flashing CM 14.1, their phone doesn't boot up. So for all those who are going to flash CM 14.1 or have already flashed it and can't get it working, this thread is for you.
What you will need:
1. Rooted OnePlus X (Obviously)
2. Custom Recovery (TWRP recommended)
3. Latest CM 14.1 build
4. Arsenic Kernel or BlackReactor Kernel
So this is how you get CM 14.1 working on your OPX (make sure your battery is above 80% just to be sure that nothing will go wrong considering battery's point of view)
Make sure you have backed up everything before performing the following steps as the process will wipe your data completely. (I would recommend to take a Titanium backup of all user apps and then taking a nandroid backup of system and data)
1. Download the required files and place them in your SD Card or internal storage
2. Reboot your device into recovery
3. Go to wipe, and swipe to factory reset (Note! This will completely wipe all the data from your device including app data and SMS! This won't wipe the contacts but just to be safe, have a backup of all your contacts)
4. Go to Wipe again, and go to Advanced wipe, select the following partitions - System, Cache, Dalvik cache. Swipe to wipe (Note! Make sure you have a backup of the System as this will wipe the Operating System from your phone!) Although this step isn't necessary, I like to do it.
5. Go to install, and direct to the location where you have saved the CM 14.1 zip file and the kernel. Select the files, and swipe to flash.
6. If you want anything else in your system, direct to that location, select the zip file, and swipe to flash. (Note! You need not flash the SuperSU zip file as CM offers Root access in developer options)
7. Reboot your system and wait for it to boot.
Viola! Your device is now running official CM 14.1 nightly.
Hope this helps! ?
Downloads:
1. Latest CyanogenMod nightly - found here https://download.cyanogenmod.org/?device=onyx
You can have any version of the nightly as long as it is CM 14.1
2. Arsenic Kernel R32 (or R31) - http://forum.xda-developers.com/oneplus-x/development/kernel-arsenic-kernel-r2-t3422020
Open the above thread and follow the guide
OR
Black Reactor kernel v1.0 - http://forum.xda-developers.com/oneplus-x/development/kernel-blackreactor-kernel-oneplus-x-t3460989

Good Evening, @aamodjoshi23 THX a Lot. You are my Hero. Finally it works.
greetings
If you're facing some Error 7 while trying to flash cm 14.1, you can try updating the bootloader following this
http://forum.xda-developers.com/showpost.php?p=69267239&postcount=2560
I used the Oxygen OS 3.13 full ROM as recommended, edited updater-script (following those instructions)
Immediately after flashing the OOS 3.13 rom, you don't have to reboot.
I immediately flashed twrp 3.0.3 original from https://dl.twrp.me/onyx/
I then rebooted into twrp 3.0.3 (using the reboot button in twrp, then bootloader)
Then I installed (in this order):
cm 14.1 (https://download.cyanogenmod.org/?device=onyx)
arsenic kernel (as recommended above)
opengapps
Not sure if this step is necessary, but I wanted to let twrp patch the rom to not overwrite twrp so I rebooted into twrp again (using reboot --> bootloader in twrp)
Then I used reboot --> system
First boot took a while, but now I have nougat!!
kenel zip every time
Do i need to flash the kenel zip every time I update the the cm 14.1 zip file?

Yes, as when you flash the CM 14.1 build, the kernel that is provided with the build is also flashed, and that is not supported. So you need to flash it every time you flash a CM 14.1 build, but if you want to flash any other build, something like CM 13.0, then you need not as the kernels provided in those are supported.

Hi,
I have a very specific problem. I rooted my Oneplus x few months back and everything was fine. I use to get update notifications and after downloading it use to update automatically. But since last 2 months i download the update files but it takes me to recovery and then i cant find the zip file to flash/install. (i also started using external sd card two months back, but not sure if it has to do anything with this). I tried searching a solution on web - tried checking 'system' under Mount tab, installed an app for auto update and some more but no use. I even connected my phone in recovery mode to laptop and copied the zip file to internal memory but while flashing it gave error.
Now i am not sure what the problem is. Do i need to update my recovery or something else. Pls help.

In October oneplus updated to 6.0.1 officially i.e OOS 3 it brings new bootloader to the device as you are using old recovery you can't flash new update..so you need to upgrade to latest bootloader by following thread available in general section or you can flash stock recovery and upgrade to latest OOS and flash whatever you want to flash..I recommend you to see how to upgrade bootloader in general section if you are planning to flash custom ROMs or if want to flash latest OOS then simply flash stock recovery and upgrade. onece you updated to OOS 3 after that you can flash new official twrp 3.0.3.0 from its official page.
Edit: for old bootloader you need stock 5.1.1 recovery..which is not available in official oneplus download page..so just follow below link

I made a blunder. I read somewhere to upgrade TWRP to 3.0.3 and after doing that now i just can't access the recovery mode. When i try to boot in recovery mode the screen gets stuck with One+ logo. Then I even tried to Factory reset and the phone rebooted to the same screen stuck with logo. I longed pressed the power button and it got switched off and then again turned it on. It started and is working fine but I cant factory set it, nor cant I access recovery to flash anything.

This is because you flashed wrong recovery twrp 3.0.3 is for new bootloader and you are on old bootloader..that's why it all happened..so you just need to flash old recovery..then follow given link to upgrade bootloader and recovery.

I've got a good news and bad news for you.
The bad news is, no one has the older 2.8.x TWRP image files and there are no threads that have the download links for the older version of TWRP. So you're stuck and you have lost your recovery. You have lost everything... Having no recovery means you can't do a lot of things like factory reset, any wipe of a partition, you won't be able to update your system, you won't be able to flash zip files to enhance your experience and many more... I'm sorry my friend...
The good news is, I've got you covered. I had saved the older TWRP so that if anyone one day would need that recovery image, I would be able to help them.
Download the older TWRP from here : https://drive.google.com/file/d/0B2Ms-zaNd3SiTmpxX0UtYUV2R1k/view?usp=drivesdk
Flash it. You should get back your recovery.

By stuck on boot, I didn't know you meant that it showed only the OnePlus logo and not even powered by Android.
In that case, follow this guide to update your bootloader :

I'm having a very difficult time getting this phone setup. I can get very, very close... but then it starts boot looping into recovery.
So starting at the beginning, here is what I did:
- Booted up phone, make sure it works and connects to wifi (I find out later that it got encrypted, even though I didn't set a PIN).
- Inside the OS on first boot, I install and use the official bootloader unlock APK from Asus.
- Rebooted into the bootloader and fastboot flashed TWRP.
- Rebooted into TWRP and flashed the Oreo modem, current unofficial Carbon OS 6.1, nano gapps, and magisk 16.6.
- Rebooted and the Carbon ROM logo comes up. It works for about 2-3 minutes, then reboots.
- After many attempts to decrypt (and a lot of help from the forum), I successfully restore the phone to "WW_ZE552KL_14.2020.1712.85_M3.10.47.15_Phone-user.raw.zip" with the Asus tool.
- Phone is fixed and booting again to the OS, but I'm back to square one.
Second attempt:
- Thinking I need to flash the raw Oreo ROM (instead of just the Oreo modem), I use the Asus tool to flash "WW_ZE552KL_15.0410.1803.55_M3.10.47.19_Phone-user.raw.zip"
- The phone works fine and is now an Oreo ROM with an Oreo modem
- It's still unlocked, so I rebooted into the bootloader and fastboot flashed TWRP.
- Rebooted into TWRP and flashed the current unofficial Carbon OS 6.1, nano gapps, and magisk 16.6.
- Rebooted and the Carbon ROM logo comes up. It works for about 2-3 minutes, then reboots.
- After the reboot, it goes to TWRP... whether I just let it boot on its own, or press power when it says: Start - Continue to boot >
What am I doing wrong?
You're having a rough go at this one eh.
I know we talked about this before, but did you try a factory reset and wiping cache/dalvik before rebooting?
Yes. As we discussed before, you can't wipe cache from TWRP. So I'd wipe dalvik from TWRP, then reboot to the bootloader to do a "fastboot format cache".
I'm going to try a different ROM later this afternoon. Maybe that will make a difference.

1) Flash Oreo RAW (can be downloaded from @Saktis_STi' s unlocking thread.
2) Boot till system
3) Flash TWRP
4) Flash ROM, Magisk, GApps
5) Reboot
The reason why it reboots to TWRP is because of 'encryption' thingy.

many many thanks! I was able to get Ressurection Remix working by now
your steps were right, and I will detail them better to tell how I made it work for others reading this thread:
1) Flash Oreo RAW
1.1 - @Saktis_STi's thread is a bit outdated. I downloaded the newest firmware from Asus website.
1.2 - I also had to find a recent recovery.img, which I think I got it from here https://forum.xda-developers.com/zenfone-3/how-to/original-recovery-img-boot-img-zenfone-t3572188
1.3 - I used the stock recovery's adb sideload to flash the stock ROM
2) Flash TWRP - all good here
3) Flash ROM, Magisk, GApps
3.1 - I wiped system, data, cache and dalvik.
3.2 - I flashed RR ROM, GApps and Magisk (EDIT 2: install all three before the first custom ROM boot, or GApps won't work)
3.3 - Performed a Factory Reset
4) REBOOTED TO GLORY!
For what it seems, the stock ROM encryption that is performed on the stock's first boot was the enemy.
Now one last thing... In Security -> Encription, my device is NOT encrypted.
Do I run the risk of ruining everything if I encrypt it?
EDIT: No, it didn't break, working fine

Hello everyone, I'm trying to flash Havoc os 3.0 alongside with BitGaps, but it always ends up in a bootloop (I always wait one hour in the "android" boot screen). My device is the A205G with Android 10. I successfully flashed TWRP using the guide posted here in xda (also flashed magisk), then I flashed Havoc and BitGaps (wiping dalvik, cache, data and system first and then doing a factory reset), but ended up in a bootloop after rebooting to system. In a second try after reinstalling Android 10 stock rom I followed the steps shown in a youtube video (can't post link since I'm a new user) with no luck (still getting a bootloop). In a third try I just flashed the stock rom, then flashed twrp with odin and tried to flash Havoc without flashing Magisk at any moment, still bootloop. Any ideas or suggestions on what could be wrong? I've only flashed one device before with a custom rom so I'm not an expert in this area, any help will be appreciated.
