I'm trying to install CM via TWRP.
First I had to unlock the bootloader, so I did, and since then I could not boot to my stock Android (although, correct me if I'm wrong, unlocking the bootloader should NOT delete the OS), it just sent me to recovery.
So I went along, flashed TWRP and got cm 10.2.1 for jfltexx. At first it didn't install well, because my data partition was not formatted correctly. So I formatted it, now TWRP sees it correctly and is able to mount it, enable MTP and everything. When I try to install now, everything seems fine and TWRP's log shows "Updating partition details..." and gives me the "Successful" message, offering to wipe cache/reboot system. (I did wipe cache and dalvik cache before, of course).
If I choose "Reboot System", it just boots back to recovery. The same happens if I power it off and boot normally, even if I pull out the battery and retry that way.
What can I do about it?

First I'd try a newer version of CM. That's an old one. It might not work and play well with a newer version of TWRP. Plus the newer version is a little more polished.
Second, if you must use that CM version, redownload it. You wouldn't be the first person who got a corrupted install file that causes screwball issues like this.
Third, if all else fails use Odin to reset back to stock and start over. Something might have gotten all borked up when you first modified the device that isn't letting the install work. A full restore to stock should correct that.

Thanks for the reply.
Regarding the versions of CM and TWRP, I deliberately picked these versions due to their high download count (A sign I can trust these builds, being not too buggy). I'll try a newer CM version and another TWRP version if that didn't help.
I will also verify the MD5 for the downloaded file this time.
If I restore to stock via Odin, wouldn't that override the recovery? I've looked on some tutorial on how it's done, and it seems like the stock recovery is flashed, then used to restore the stock. Is there any way to use Odin to flash other ROMs?
EDIT: Nope cm-11-20140210 also failed, and I did verify the MD5 now. My TWRP is the newest available for jgedlte in the download page (2.8.0.1).
I did manage getting into some sort of a boot loop (The initial "Reboot System" brought back the recovery, but after a full power off and a reboot, the screen remains black and the phone vibrates every 4 seconds or so.)
EDIT 2: I tried to flash the stock back, following this tutorial. I downloaded the Open European version, flashed the AP but it failed during the write of system.img.ext4, saying that the image is invalid. I tried again with the PIT file, but it failed too (secure check fail while repartitioning...).
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).

I officially upgraded to 3.0.2, unlocked and rooted my phone.
It was fine for the first few times I flashed multiple ROMs. But ever since I flashed Exodus, I keep having issues switching to different ROM.
A week ago, I flashed "Switch to OOS3_H2OSMMv7" zip and was able to flash Resurrection Remix, but today when I tried switching to CM13 or PA it gets stuck at flashing the ROM zip. I tried flashing the firmware zip again and flash the ROM, but to no avail. It won't flash any ROMs now, just stuck at recovery while flashing the zip.
I have a working fastboot and recovery mode though, so I'm trying to avoid flashing the entire factory image but that seems to be only option left. Does anyone have any clue as to why this is happening and how I can fix it?
Edit: Resurrection Remix gets installed fine, CM13 and PA still giving me issues.
Edit: I downloaded the latest version of CM13 and it works. Earlier I was using June 30 build which seems to have issues with the new firmware. I'll try out the new PA build to see if it fixes that too.
What error does your recovery gives?
Do you have Data Backup?
Can you access ADB while in Recovery?

It does not show any error as it just looping while installing the zip. I have to force shut down the phone to exit it.
Yes, I have backed up all my data
Yes, I am able to access my phone in both ADB and in fastboot modes.
After flashing Custom ROM, Wipe data, cache, d-cache and then reboot.
If still doesnt work try flashing another custom ROM. You can use adb-sideload to flash another zip in recovery mod.
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...

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.

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
