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).

So I got my 6GB/64GB x720 yesterday. It had Google Play Store already installed (ordered it from HonorBuy) and asked me to install a 7MB OTA, so it seems it had a recent version of EUI on it. My idea was to put LineageOS 14.1 on it or if it wasn't stable enough for me, at least a debloated and rooted stock. So searched XDA and followed this HowTo. No Errors, flashboot oem device-info said, bootloader unlocked, perfekt. Installed TWRP, downloaded recent LineageOS and followed the guides to flash (wipe, ...). Unfortunately flashing never finished, I always had a full progress-bar and it stayed there without doing anything (ok, the device got hot). Thinking of a broken download, I redownloaded the ROM but same problem. So I started downloading other ROMs from XDA: Resurection Remix and OmniROM. Flashing-process went thru, but couldn't flash gapps and ROMs didn't boot at all. I was always only getting to the LeEco-Bootlogo with the chinese writings. So next thought was, maybe for some reason I can't install Lineage-based ROMs, let's figure out later and get a debloated stock ROM. So I downloaded MAURO V2.2_Free and gave it another try. Looked more promising, as the bootlogo was a little different, no more chinese writing but english. Unfortunately this was all I could see of MAURO as I only got a bootloop... so again reflashed MAURO and this time a single line in TWRP-output came to my eye "boot.img could not be written". I checked flashboot oem device-info after every flash and it always told me, bootloader is unlocked, but there seems to be something else that I'm missing that obviously still keeps the bootloader locked. I wiped the phone several times, even sdcard... nothing helped. The only method that worked for me to get a working rom running was by this guide, manualy flashing every bit of stock ROM with flashboot. With MAURO-ROM, I also tried to flash boot.img manually with flashboot, but that didn't work, either.
Anyone of you experienced the same? What am I missing? Or is this some new protection implemented by LeEco for the most recent devices? Any help really appreciated!

I have the same phone from Honorbuy, I flashed twrp using the tool by Mauronofrio and from the twrp wiped all and flashed the custom rom, all went ok, no errors at all! Glad to see you have solved anyway!
Thanks for the answer... no, it's not solved for me... still a lot of bloat on the phone I can't get rid of. Do you have a link for the tool you mentioned? Could be worth a try...
Hi! I've used this tool installing it on a Windows 7 64 system:
https://forum.xda-developers.com/le-pro3/development/tool-tool-one-mauronofrio-t3580611
Then turned ON the (original LeEco stock rom) usb debug option by the rom's developer options, then downloaded the LineageOS 14.1 by Team Superluminal in the phone's internal SD (the only SD it have!) + Arm64 nano Gapps, then with the tool gave a reboot in sideload mode. Then flashed the twrp recovery by the tool, restarted in recovery mode then executed a backup of ALL the "backupable" stuff (all the original rom and data and efs), then in wipe/advanced options I wiped dalvik, system, cache, data. Then in Advanced/file manager I wiped all the SD files with a dot ( . ) at the beginning of their names, then flashed the custom rom + gapps, reboot system, wait some minutes, done!
No luck with this tool, it doesn't even find my device. Any other ideas? I've read something for the x727, where they had to flash a 19s bootloader first, but I don't want to fiddle with flashing files that are not 100% meant for the x720...
CDFS
Solved! As I could install TWRP I just went the next step and installed SuperSU (rooted the phone) in order to at least debloat stock rom. During the installation of SuperSU I saw, that SuperSU obviously patches somehow the bootloader. After checking that SuperSU worked in the ROM, I was curious if this could be the missing part I was searching for. I tried to install a LineageOS-based ROM and BINGO! it just went straight through! From my previous phones I was used to just install TWRP, wipe anything and flash desired ROM. This seems to be different on this device... so the proper procedure to be able to flash any ROMs is: Install TWRP, root stock ROM, reboot so SuperSU is fully functional, then go back into TWRP, wipe, flash what you want.
CDFS
I hate to say it, but it's still not solved. After testing Resurrection Remix, I wanted to test turbos ROMs, so went to TWRP, wiped and flashed... and got the same behaviour as before, ROM not booting. Also installing SuperSU via TWRP again didn't help, so brought back the phone to stock 023S manualy with the guide by Presterin, installed TWRP again and also SuperSU. No Errors, but flashing a different ROM didn't worked. So for now I'm back to stock, rooted it and tried to debloat it by myself. The only difference between the successful flashing and the failed was the stock version: I had the 026S-update when I rooted the phone and successfuly could flash another ROM. My guess would be that LeEco changed something in the bootloader, but I have no chance to verify this. Anyone from the devs maybe who could look into this? If you need dumos, logs or anything like that, I would be happy to help.
CDFS
This seems unrelated to bootloader.
Anyway:
1. Make sure you got the latest firmware, if not sure:
1.1. Download latest OFFICIAL ROM
1.2. Rename the rom to a 'update.zip' and place it on phone's root directory.
1.3. Reboot to fastboot and flash STOCK RECOVERY
1.4. Reboot to recovery and flash, also check wipe data.
DO NOT FLASH STOCK ROM WITH TWRP! THIS WILL NOT WORK!
That's it, you should have the latest firmware now.
After booting to stock rom, reboot a few times is recommended.
2. Download latest OFFICIAL TWRP
2.1. Flash TWRP with fastboot.
2.2. Reboot to TWRP.
2.3. Download any custom rom of your choice.
2.4. Wipe.
2.5 Flash.
Done.
You can try to flash a stock, old rom using the "Qfil/FlashOne" way as suggested by Tryzex (read his thread and other related threads), then once you have got a stable, full working phone, you can (hopefully!) wait for a LeEco OTA automatic update that can "repair" the file system/partition structure (also bootloader I hope!).
Btw, to debloat it isn't necessary to root the phone, you can keep the phone unrooted & debloated using the file manager embedded in twrp recovery to delete/replace any file/app you want. I'm sorry I can't help you better, cheers and... good luck!
PS
I see now the post from Voron00, it's a good hint!
@voron00 thx for the steps described. I'm using the most recent, official TWRP (3.1.1). Latest Official Stock seems to be 023S on their site, even though there is a 026S update. However, I did this 026S-update and rooted again, but was to cusious if flashing would work now... so I tried flashing turbos MIUI... guess what? It worked. So for whatever reason I seem to have trouble when flashing from a 023S, but no problems when flashing from 026S. I don't quite understand why you think that my problem is not related to the bootloader? As mentioned in the OP, I could see in the logs that while flashing, some roms had thrown errors regarding writing the bootpartition.
CDFS
Seems as I found the culprit, somehow. At least I could flash two other ROMs without any problems. Obviously I mixed and partly missinterpreted some steps found in different threads and howtos. I had "rm -rf for formating" ticked all the time in TWRP. My flashing procedure is now as follows:
1. in TWRP settings check that "rm -rf instead of format" is NOT ticked
2. wipe Cache, System and Data
3. repair filesystem for Cache, System and Data and check that no errors occur
4. in TWRP settings tick "rm -rf instead of format"
5. flash ROM
6. wipe Dalvik
CDFS
"rm -rf" clears all the files and directories without formatting the partition. If your partition is damaged you need a real format to obtain a reliable partition (if the "disk" isn't faulty). Perhaps in your case a real format was required to solve the problem! I always used the real format and assumed other users even so. I see you finally solved the problem!
I am currently using a OnePlus 5 which used to run on a stock based rom, xxxNoLimits v3.1
Since the dev ended the support I wanted to revert back to pure OOS, so I downlaoded the newest 5.1.5 zip and followed the instructions using the newest blu_spark twrp recovery but right after pressing the "flash" button I kept getting error 7, so I download the zip from a mirror link and I have also tried the newest version of codeworkx twrp, still error 7. Then I tried flashing the original stock recovery in order to flash the zip but it instantly threw me back to the zip selection menu, flashing the zip via adb sideload kept quitting at exactly 47%. At this point I was pretty frustrated, I flashed twrp codeworkx again and wiped EVERYTHING, which includes the system, data, cache, dalvik partitions and then I also did a format on the data partition, the point was that now I would have a clean phone only running twrp and I thought I could easily flash the newest zip now without any problems, NOPE, still error 7!!! Now I am stuck here, the stock recovery doesnt let me flash anything and I've tried 4 different versions of twrp recoverys and every single one gives me the same error, I even dug up an older version of OOS, I think it which I had running for a few weeks without any probles so I knew that the zip was not corrupted but same error
Now I had given up and wanted to restore the backup I did just in case anything goes wrong, well, restoring the backup fails when it tries to restore the data partition, so I unchecked everything except system, system image and recovery but it didnt work, now I am sitting here with my phone telling me that there's no OS installed. any advice?
Use Unbrick Tool and Restore
Hey,
You can Flash your Mobile using the Unbrick tool at - https://androidfilehost.com/?w=files&flid=204903
Use the Latest file which I guess comes with OOS 5.1.3 - https://androidfilehost.com/?fid=962339331458999196
If you try to Go to Open Beta ROM First Flash Open Beta 12--> Open Beta 13 --> Open Beta 17

Hi ! Do you have some news about it ? I have the same issue since Monday...
I've tried like anything i've found and even more, but nothing did the job ...
The only way to have my OP5 working is downgrade to an old version running Android 7.1.1
Hi,
I have a rooted OP5, running 5.1.7 and TWRP. I used Oxygen Updater to download the new android 9 ROM. I tried to install via TWRP, but got an error about zip compatability & a treble problem. I found a thread stating that I needed a newer TWRP to fix the treble problem, so I installed TWRP_3.2.3-Pie_siankatabg_OP5 , which said it had Pie support, from here:
https://androidfilehost.com/?fid=1322778262903996029
That worked fine, but when I tried to flash the 9 ROM, I got still got the same error. Another post said to remove compatibility.zip from the ROM zip. I did that, and it now installed, but it wouldn't boot. Re-flashing 5.1.7 booted fine. I tried another TWRP - twrp-3.2.3-0-20181227-codeworkx-nocompatcheck-cheeseburger from here:
https://forum.xda-developers.com/on...overy-twrp-3-2-1-0-oreo-oxygenos-5-0-t3725723
That installs, and boots to system, but won't boot to recovery, so I can't install the 9 ROM.
Any ideas where I go from here to upgrade to 9?
Thanks!

And follow my post on the part where it says:
" Notes for the Pie update: "
Let us know if those steps work for you. The firmware is linked to on there, pre-modified. Try flashing that pre-modified zip and see if your device boots.

It sounds like you did not follow the detailed flashing instructions in the first post here: https://forum.xda-developers.com/oneplus-5/how-to/official-oxygenos-4-5-2-7-1-1-ota-t3627003
Is your device storage encrypted or decrypted? Have you flashed magisk? Have you used an older magisk(your end link leads to my post where I mention that)? Have you downloaded the rom file without compatibility.zip or did you removed it on your own?

Thanks for the links both, but still no go. I was on Magisck 17.1, uninstalled Magisk with the latest uninstaller, flashed the ROM with compatability.zip already removed. Same result as before - I get the oneplus logo, then it just reboots instead of starting the system. I've only wiped cache & dalvik, I don't really want to wipe more than that if I can help it - it is worth trying a system/vendor/data wipe? I recovered by flashing back to 5.1.7 (also updated to Magisk 18 while I was at it).
Any more ideas? One thing I find a little weird is that I'm on the @siankatabg TWRP, when I tried either the bluespark & codeworx TWPR, I couldn't get into recovery with either, I just got a blank screen with a LED staying on light blue. Only the siankatabg recovery works. Surely any of them should work? Does this point to a problem?
I'm not sure what you mean by encrypted or not - I get messages about unencrypting when going into recovery, which I assume means I am encrypted?
THanks!

Maybe try backing your device up, and then locking the bootloader. Try updating with stock recovery on a locked bootloader. If that works, you can then unlock the bootloader and copy your data back

Please use an older recovery like twrp-3.2.3-0-20181031-codeworkx-cheeseburger.img the actual pie recoveries require pie firmware(mentioned in last post of blue spark thread for example).

OK, I understand now - if I use an older TWRP, or the siankatabg version, it works fine. I can then flash the Pie ROM, however it still won't boot - I get the oneplus logo, then it just reboots. However having done the Pie flash, I can then flash the more recent TWRPs (codeworx or Bluespark), and can now get into recovery fine. However Pie still won't boot - I've even tried re-flashing the Pie ROM from within the newer TWRPs, but the result is the same - it gets to the oneplus logo, then reboots. At this stage I guess wiping system/vendor/data is the only way forwards?
*Edit* - OK, so wiping everything fixed the issue, I'm now on Pie. Flashing Magisk didn't work when flashing the ROM, but I'll try again once it's finished downloading all my apps etc.

Had my new OP5 rooted and almost everything was right in the world, but i flew too close to the sun by uninstalling a few apps I thought were expendable and eventually Google Play Services started crashing. When all troubleshooting failed I ended up flashing a fresh copy of OxygenOS (5.1.7) to my device, but every attempt to re-root the device has failed.
The first obstacle I ran into was that there was no access to Internal Storage in TWRP, I was able to fix that by Wipe > Format Data and then using Advanced Wipe to clean Dalvik/Cache/System/Data for good measure.
My next issue was that TWRP returned Error 7 when attempting to flash the stock OOS rom... after some digging I was able to clean the 'asserts' line from the updater-script file and now the rom will flash.
The headache has been getting the device re-rooted, and I feel like I've tried everything. I have to flash the SuperSU or Magisk zip (both fail to root the device) before reboot because the dm-verity encrypts on first boot and after that I can't access any storage to flash from internal memory. The three different dm-verity patches I've found don't prevent it. I also tried 'fastboot oem disable_dm_verity' to try and stop it but after talking with the device fastboot returns 'unknown command'.
My final effort to get around it was to flash a kernel that didn't force dm-verity (blu_spark kernel) but that returns Error 1: 'Unsupported Android Version' when I attempt to flash it.
I've tried dozens of variations on this, including a Lineage OS rom instead and also trying to sideload certain zips, but still no dice. Any and all help would be appreciated.

Hi, this one is because of your TWRP. Please flash Codework's TWRP and try that with it. It should solve your issue for sure. (same thing happened to me while I tried installing custom roms and every time I needed to wipe everything to see my internal storage again)
This guide can help you out with Error 7 on TWRP https://forum.xda-developers.com/showthread.php?t=2522762
I do believe your this issue you're having caused by TWRP. Also after rooting the phone, install magisk app. (you don't need to install supersu, it comes with magisk). After rebooting into system reboot your phone again once more it should show up on magisk app that you've successfully rooted your phone. Remember after flashing magisk you need to reboot twice in order for phone to realize it. Please try the steps I told you and let me know.
Also you don't need to flash dm-verity patch at all.
Try clean flash instructions with Codework's TWRP and root it with latest Magisk.

I actually really like the Oreo version of OxygenOS, so when I had to resort to re-flashing to fix this mess I dug up one of the stock (5.1.7) roms, it served me well (assuming I can get it rooted, lol).
I'd be willing to move to Lineage if I absolutely have to, but if not, I'd really like to keep Oreo if at all possible.

For 5.1.7 try this twrp https://drive.google.com/file/d/1UlTftbe6wooAs4Fp0cjwXlOKmfQHgdfL/view?usp=drivesdk along with magisk 17.1.
Clean flash is recommended. If it didn't help, please list your steps again(detailed).
Don't use supersu and skip the other suggestions for now please.
