Well I did have the same problem this guide bring it back to life. Then I followed the steps from this thread which didn't work for me and at the end I did this:

fastboot erase modemst1

fastboot erase modemst2

fastboot erase persist

Then I flashed OxygenOS 1.0.0 and the phone is running normal!
[ONE Q&A, Help & Troubleshooting] nysfinest318:
Hello folks! I'm having some serious issues and after literally 10-12 hours of pouring over XDA and every other forum that I'm a member of, I can honestly say that I am at an impasse. I am not one to casually beg the assistance of others simply because I am too lazy to do my own legwork. TBH, I actually enjoy the challenge and the satisfaction of knowing that I solved the issue through my own research....but mostly through my ability to find the answers that you geniuses have come up with, LOL. But, this time I'm stuck and need to consult the GURUs. A quick note to begin, I'm not exactly a novice as I have been an Android fanboy since receiving my G1 on the day it was released and I've never owned a Fruit Fone since! I've owned every Note since it's inception and have rooted, flashed, unlocked, etc. every phone I've ever owned. So, suffice to say, I'm an experienced noob.

I'll try to be as explicit in my explanation as possible because I know that the more info you guys have, the better the chances that the issue will be resolved. My OPO 64GB which was rooted and running a custom rom ( I can't remember which one because it's a backup phone that I let my 13 year old carry) was running fine one morning and a few hours later, it was unresponsive. To clarify, when I power it on, there's no boot animation/sound but it does vibrate and I can vaguely see the screen turn a "brighter shade of black" for lack of a better description. Immediately, I figured I'd just do a factory reset because as a backup unit there's nothing on it that I can't afford to lose. But to my dismay, I can't access recovery, fastboot, ADB, nothing. I know my drivers are good but I reinstalled them just to be sure. When I plug/unplug the phone into my pc I can see that the pc recognizes it but it's not communicating with it. When I plug it in, initially my Device Manager identifies it as a One Plus One A0001 I believe but after about 5-7 seconds that goes away and is replaced by "Marshall London HS-USB Diagnostics 9006". When I attempt fastboot, I get the message "<waiting for any device>" and then nothing. It's almost just like what happens when you try to fastboot but haven't enabled USB Debugging. Which I would, but I can't access the system...at least not in any way I've been able to find. Any help that can be provided would be greatly appreciated. My son is having a fit because I gave this to him on a probationary period to test his readiness for a phone and he's driving me CRAZY asking if I fixed it yet.

Any help.....anyone?

Looks like my persist partition got corrupted after restoring a backup via TWRP, its really driving me crazy, I'm gonna update this post if I manage to get a breakthrough but flashing stock COS12.1S via fastboot isn't helping

Symptoms I'm experiencing are that I have no WiFi and my sim card isn't recognized and because of this my phone constantly reboots at the set up screen, tried flashing the persist but nothing so I'm currently downloading the nightmare_fix zip and hoping for this to be resolved

[MENTION=5098295]markbencze[/MENTION]

These commands should be featured more prominently

fastboot erase modemst1
fastboot erase modemst2

They saved me a lot of grief. After I used

fastboot flash modem NON-HLOS.bin

Finally I have WiFi, network, baseband etc and the bootloops have stopped, thank you so much for this guide

I'm certain I have that in the op. I'm not really active at all these days especially in this thread. I've got everything posted that fixes the problem described in the OP so there's basically nothing left to do here. I kept the thread open because it seems people are running into various issues that are similar to what the original corrupt persist issue was.

That and I don't use my 1+ much these days. It treated me well but I've moved on to better devices!!!

This worked a treat, spent all weekend googling for fixes, running opo toolbox and alike and stumbed accross this thread. I followed your guide and this has worked:) you and the contributors are amazing!

Flashed a few fones and tablets before but tbh I'm a noob really. Bought the opo a 6 months ago and was talked into going back to cm11 and thats where it all went wrong!:(

Now I'm a happy bunny, so Thanks.:)
[ONE Q&A, Help & Troubleshooting] Mxoc:
Just asking..

Hello everyone.

I created nearly the same issue for my opo and wanted to know where to start.

My state is : *#06* gives me an IMEI, Settings tell me i have a baseband ( which is new because in cm13.0 latest nightly i had none - then flashed pacman Rom LP-MR1 official. So well..)

I have access to wifi, but my sim-card is not recognized. So im feeling kind of "in between different states". My phone is rooted, unlocked, has latest twrp installed AND i have my efs-backup folder in the phone.

What I also tried was to

fastboot flash modemst1 modemst1.bin

fastboot flash modemst2 modemst2.bin

But terminal gave me an error. ( erasing them is the next i would try while being at home again. - or is there a way to fastboot without a PC?)

After that i flashed gapps to have access to download "es Datei Explorer" for checking the folder where modemst1 is located and see if they are there.. But found nothing..

So.. My question know is .. Where should i start according to the guide of "markbencze"?

Thanks in advance!

Edit : 9 hours after initial posting:

-----------------------------

Well it did not work.

I tried to flash Oxygen ( like "consciyash" said it worked for him) - i got a bootloop. So i did with Bacon Root Toolkit a back to stock for softbricked state. Now im not root anymore and have stock recovery. But still unlocked Bootloader.

Now every time i try to root again and flash a custom rom ( Out of BRT ) it bootloops at android 5.x.x e.g LRX22G (CM 12.0 YNG1TAS0YL). At Android 4.4.X i received plenty of errors like : " unfortunately AudioFX stopped working" which appears a Centillion times until i finally unlocked developer options and activatet the developer bridge.. for rooting again. Maybe this time im getting through all the process without a second error message on the homescreen which screwd up everything..

I think I have hard bricked my phone after flashing cm-11.0-XNPH30O-bacon-signed-fastboot_64GB.zip. It won't boot or show the OnePlus logo while booting or even go into fastboot mode. I plugged the phone into my computer and it detected something was plugged in after I held down the power button (on my phone) for ten seconds.

OPO low signal

my OnePlus one ultimately takes little signal, or rather seems to take on the bar, but if you then try to make a call, often says call terminated. often also I have problems in calling others I feel bad my voice, all in the points at which people with other phones with the same operator takes the signal well. in the settings, time spent without signal hardly exceeds 10%, enclose the screen.it is possible that you have corrupted partition efs? wifi and the signal goes well, but was very weak, I tried several modems h2o and oxygen and with different rom, I also switched operators, without clear results. or it may depend on the bands blocked? certainly the OnePlus one is not a champion in the reception ... but I would like to know if someone is in my situation and what are the causes and possible solutions. thanks and sorry for my english

fastboot erase modemst1

fastboot erase persist

Then flash Oxygen OS 1.0.0

**** One most important part of this process is TWRP 2.8.6.0

havent tried the older versions but newer TWRP than this doesn't work. This will save you a lot of time.

oh, the phone behavour is unusual for bricked efs, too, i have no random reboots, I can use it normally, theres simply no baseband and IMEI.....

[ONE Q&A, Help & Troubleshooting] jayanta525:
Had the same problem, tried flashing cm11 30O , didn't solve the imei problem, came to cm13 nightly , sloved WiFi and Bluetooth temporily, still no baseband, lastly tried OxygenOS v1, before flashing erased modem, modemst1,st2 and then flashed through unofficial twrp, I was amazed , oxygen brought my imei, Mac address back, after that instantly backuped my efs, and persist for future

OxygenOS had these touch sensivity problems, did a factory reset in twrp and flashed cm13, working fine now, but just after reboot it shows a fake WiFi Mac address, gets corrected itself after some time. Working smoothly now. :)

Try "fastboot erase modem,modemst1 & 2" and then flash OxygenOS, might help

Okay so I'm a little confused. I have stock cm12.1.1

Bootloader unlocked

I can install twrp no issues through fastboot. But I've tried to installed cm13 by dev sultan and it goes into bootloop. So I went back to cm12.1.1 with flash.bat file (goes back to stock basically no root) and tried again but installed cm12 by dev sultan and yet again bootloop at the CyanogenMod face. What I'm confused with is I did the fastboot flash persist.IMG and had no problems but didn't change anything? Still had bootloop going into new ROM. And I tried just typing into twrp terminal with keycode from the OP but it couldn't find partition? I believe that's what it told me. If you guys can help that would be awesome. Really wanted to hop onto cm13. Thank you.

[ONE Q&A, Help & Troubleshooting] Renosh:
Yes, don't use the flashall.bat file from CM11, it'll brick your phone. Do the commands manually then reboot, the reboot after every command is what causes it.

Follow this guide in first post and you should be ok, you'll have to long press power button to turn off and then turn it on. Connect to PC and check for response (screen will be black throughout) then use the instructions in the first post. Make sure you have the USB drivers and you should get your phone running soon

6. I tried flashing using the msm tool! still not even an ounce of luck!

7. then i tried flashing cm11 stock rom 64gb for opo that didnt work either.

8. i even tried the Brickloop/audio FX FC/EFS corrupt method on XDA by markbencze, and by now you can guess the result! still NADA! ****ing no luck! it doesnt seeem to wanna get outta the boot-****ing-loop! so please for the love of almighty zeus and medusa and whatever Gods there are somebody please show the way, show me the light at the end of the tunnel! please i beg of you! its been almost a week n half now! i am going crazy sick without my opo! i cant insta, i cant fb, i cant 9gag, i cant whatsapp, i cant hike! i cant fukcign watch youtube, i cant do anything!

You can fastboot flash the userdata partition from an older COS version from here

http://xdaforums.com/showthread.php?t=2906746

You'd have to download the entire fastboot zip though.

Flashing userdata will wipe internal storage so backup your pics and other data to PC first.

Alternatively you can check the unofficial recovery in Android Development section I think it has a function for converting the data and cache partitions.
