A few people have had issues with the EFS getting corrupt or wiped on their OPO before they had a working backup. This guide has so far worked for 4 people to restore their EFS allowing them to access mobile data and bluetooth again.
Note: I really don't know why this works, I have contacted the dev of this rom to ask if he has any ideas but still waiting on a response.
1. Flash official TWRP
2. Flash this ColorOS rom using TWRP - http://forum.xda-developers.com/showthread.php?t=2772627 (you can skip all the account setups if you want)
3. Factory reset
4. Boot and setup ColorOS (you should see a network connect now with your sim card inserted, you will need to toggle mobile data on to test that)
5. If you have data in ColorOS you are good to flash back to CM11S anyway you want (you will need to factor reset after flashing back)
6. Save yourself the headache in the future and backup your EFS
Please post if this fix works for you.:victory:
Edit: I've went ahead and downloaded the ROM and I will hold on to it incase the original mirrors go down for some reason. Please PM me if they do.
One of the ones who can confirm this works. Will post in the official thread.
Worked for me also.
Wholy moly ... I have a mobile data network !!
Still on ColorOS, but this is VERY promising !!!
IMEI is correct, it's the one on the box !
Still no WiFi nor Bluetooh mac addresses, though...
Will keep you posted, but this is a HUGE step forward !
Thanx a lot for sharing this !
BTW, serial number is still unchanged and correct.
JP.
EDIT:
Unfortunately it didn't fix my issue, back to CM11S I am greeted by an AudioFX FC... Device pretty much unusable, the FC pops up the milisecond you click OK ...
Will try a different ROM...
EDIT 2:
SlimKat, CM11 Nightly both boot to the welcome screen, then reboot about 1 second later.
Only ColorOS seems to actually run ?!
A bit disgusted right now

Official TWRP doesn't have EFS backup in it, you have the get the unofficial one http://forum.xda-developers.com/oneplus-one/development/recovery-unofficial-twrp-2-7-1-0-t2815247

Odd, maybe you could try using TWRP to delete everything again including system, then sideload and boot ColorOS.

To add to that you can just boot the unofficial recovery using "fastboot boot recovery.img" to do your efs backup if you would prefer to keep the official TWRP installed. That way it only boots that recovery to allow you to do the backup of your EFS partition and doesn't erase your current recovery. That's how I did it.

WOW thanks, i do it and and i tell you how did it go in a few minutes.
I see that the OP has been thanked and this thread has a few success stories so I am giving it a bump for others to view in case of the same issue.
I just flashed the factory image... I never had the problem again

Im having the same problem as you have Yank555. It started with the AudioFX FCs rendering the device useless.
Next i tried to reflash the standard CM11s 25R rom back to get my phone normal again, it didnt work.
Then i remember i have a nandroid from a few days ago. Not thinking to read up on known issues with the OPO EFS i tried a restore.
My EFS is gone and the phone will not work unless im on ColourOs120. Wifi doesnt work, just basic phone functions.
Still waiting for a miracle for this problem.
Any suggestion guys?

Did you open a service request ? Any response ? So far all I got 5 days later was a "please fastboot flash factory images, case closed." which quite obviously did not help, so case reopened, but again nothing from them in 4 days, now.
But I wonder if my first thought is still correct, flawed emmc as flashing seems to work ... might be a radio hardware issue ? Just don't quite get what the AudioFX has to do with that... cause simply rooting the device and installing apps and making a few nandroid backups is no way to brick anything.
But anyway, tbh, OnePlus is mostly dead to me as a company, worst invest ever so far, nice if your device works, but service is not even close to bad, it's pretty much non-existing ... and for a supposedly "best service ever" it's quite, let's say, "impressing"

Nope, i have not tried opening a ticket, mine is a grey import from China.
There is something terribly wrong somewhere hardware wise. The audiofx problem only happens if i flash the CM11s. After ColourOS i have tried flashing the CM11 M8.
Im also wondering if i should try to use this OPO made rom to see if it can help.

Give it a go, not much to lose. Didn't work for me, though.

Sent from my Nexus 5 running stock rooted AOSP on Yank555.lu v1.0-alpha5 kernel.
This worked for me! I'm back in business! Thanks guys for getting this figured out, I thought my phone was done.
I hate to bring this back up.
I have a Nandroid of my stock CM11S on my phone. I used it for the update to 300 to get firmware, then made a backup of it and went back to the custom Rom I had been on.
Today, I went and restored the backup of CM11S to sideload the newest update. Weirdly, after restoring I have an unknown baseband. But if I go back to the custom Rom backup I still have a baseband.
I wonder if TWRP just didn't backup the correct partitions? I am on the offficial TWRP. But I do have a backup that contains my EFS backup from the other TWRP that has that option.
I think I know what corrupted my efs....I used the official twrp 2.7.1.1 which for some reason saves modemst1. I remember restoring st1 when I corrupted it the first time with the official 2.7.1.1. Well I did it again trying to restore a nandroid with the official twrp 2.7.1.1. Do not restore the saved modemst1 from the official twrp 2.7.1.1. You will encounter problems.
So, this same thing happened to me...i happily using 30O and not really any issues and getting good battery life~17 hrs w/moderate use. And no other bugs.
Found the 33R update here on the forums and downloaded it and flashed through TWRP.
Thats when trouble found me, lost network and wifi stuck trying to turn on but never finds wifi. Then reading through xda someone suggested to check IMEI and it was gone. I had NOT done any prior back ups other than Nandroid prior to flashing update.
Restore still didn't fix it.
I tried this (flash ColorOS and CM11) but still didnt fix it. I was bummed as my OPO is very new and I had been happy with it.
CM11 or by restore, windows will not detect it even with drivers loaded. Flashing colorOS would allow windows XP to recognize internal and allow me to send files so i tried custom ROMs and CM stock and Mahdi but none worked. Luckily my TWRP still works and i am able to boot and get into fasboot.
I finally got mine fixed with rooted stock 33R from here on xda!
Now my OPO is back in business!!!
Save st1 and st2 with vonnegut's method http://forum.xda-developers.com/showthread.php?p=54623075.. Put it in a safe place for later. I uploaded them to google drive and onedrive . It saved me today.
For those of you that were able to recover, did you lose your entire EFS folder? Mine is completely gone and I don't think this ColorOS trick works either. I've tried it all last night and I fell asleep at my desk
Hi all,
Some time ago i asked, and received, some support on these forums on how to properly carry out a nandroid backup... following the sound advice i got, i carried out my backup (using TWRP for the record, with all the options checked), and stored it away for a rainy day... said day came yesterday, when i messed up my system and rendered it instable (i tried to manually delete the dalvik cache directory in order to free up the 2,5GB of space it was taking)... since i knew there was i high chance of this ending in disaster, the last thing i did before the delete was carry out another nandroid, so i could easily return to where i had left off... how wrong i turned out to be
as soon as i the system became instable following my experiment of deleting the d. cache directory, i recovered the latest nandroid (i.e. the one i had made just hours before) and everything seemd to go smoothely until the first reboot... when the following happened:
- first reboot after recovery took ages, much like the first reboot following the flashing of a new rom... not the end of the world, but that was the first sign that all was not well
- the status bar disappeared, and there was no way of making it come back (i.e. nothing to do with the launcher, i typically use apex but i i tried switching to both nova and touchwiz which i also kept up to date but the stats bar was nowhere to be seen)
- even if not having a status bar with all the info on it is acceptable (which of course it isn't, but lets just say), the sytem became completely instable after 5minutes of operation... with each app taking turns to shutting down until i kept getting the message "system UI has closed" over and over, to the point that doing a reboot was challenging since i barely had the time to press on the screen between instances of this bloody error message appearing...
...i did of course try and return to my older nandroid backup, but... lo and behold... exactly same behaviour...
so now i have resorted to formatting the internal memory card and flashing a new rom and basically starting over... just what i hope the nandroid would spare me basically :/
question is: does this sort of error sound familiar to anyone? can someone give me a tip maybe on what i may have done wrong?
any opinion, tips& advice much appreciated
I have the exact same problem. It happens on TW Lollipop ROMs. Haven't found a fix. I'm using Philz Touch Recovery and the old no knox bootloader.
Anyone? I have researched this but cannot find any similar problems reported... it can't just be me and pavelcheto...
Maybe it a recovery fault. Faulty backup or faulty restore.
No problems with my older backups. I restored my KitKat TW backup, working fine. Restoring CM12 backups also works fine. I've looked for a new recovery, Philz is discontinued, CWM hasn't been updated for a year and I really don't like TWRP.
I use TWRP 2.8.3.0 and never have (and hopefully never will) encountered any issues with restoring backups.
Considering i recovered 2 separate backups for a total of 3 times (i tried recovering the first backup twice) i doubt the issue was with the recovery itself... however since pavelcheto had no issues with the kk recovery maybe it could be lollipop related?
Anyone successfully recovered a lollipop nandroid backup?

I recovered my lollipop gpe backup a couple of times without a problem.
Data encryption may cause restoring problems.
I have restored CM12 backups (based on 5.0.2) serveral times, no problem there. I've had issues only with TouchWiz Lollipop ROMs, I have tried different custom roms, all get bugged at restore.

Just to make sure I understand correctly : you mean all TW custom roms you've restored have had problems?
Wonder if anyone else has managed a bug-free restore of a 5.x TW?
Yes, but only on Lollipop. KitKat TW roms restore just fine. I am using Philz Touch Recovery. I have tried 3 different TW Lollipop roms and they all fail to restore properly. No wallpaper, black wallpaper and no status bar. And after a minute or two System UI starts crashing. If then I do factory reset from recovery and the rom starts normally (welcome guide and stuff) and works fine.
bumping this thread because i cant seem to find a solution for this anywhere.

There's no solution for this as per comments above. TW LP is not restorable. You can flash a new lollipop ROM tho'

Hey guys,
First of all sorry for my not perfect english
Well pre story: my mom and me using both Note 4 but my one has WiFi issues since day 1 and she told me today to change the phones bcuz she dont care if 1mb/s or 5.
So I did something i never done before -.- rooted her Phone, installed twrp and made a full backup via twrp(ticked everything active) so.. moved the backup file into my SD and restored on my Phone.
Everything went good but i recognized a lot of lag after first Boot AND WiFi dont remember the saved Networks. Turning WiFi off happens instantly but turning back on Takes around half to a whole Minute.
What i tried so far:
- factory reset via twrp
- factory reset via Standard cwm
- flashed Modem and bootloader with odin (cok1)
- reverted back to kitkat
- flashed clean 5.1.1 cok1 with odin
Tried something with .pit file while installing but didnt recognize any difference..
So.. May the restore file destroyed some specific partitions? I havent got any clue What to do next :/
Any help or advise ?
Maybe i shouldnt restore efs to my moms N910F?
Nvm solved after i restored my luckily made efs backup
Hi all. had an issue while trying to load up LinageOS last night. Was having trouble with keeping root. Seem to have solved that by using Magisk 11.6 and the SUaddon rather than any superuser version.
Anyhow as part of this i went back to a TWRP backup of which i had 3 different versions (stock and lineage) available being a bit ocd with backups. They all flashed ok, but for ALL of them, when the phone booted it kept telling me had wrong pattern when i tried to unlock. Not good. Thought only way back was to factory reset and do all the app loading and setup again.
After a bit of searching found this thread and this post.
https://forum.xda-developers.com/showpost.php?p=69189392&postcount=65
Worked a treat.
The other methods didn't and i suspect are obsolete.
Anyow, posted for info if anyone else runs into this problem. Success dependent on having working TWRP and being able to boot to that as you need to use the File Manager capability in TWRP.
Seeyahs!
Same thing happened to me last week, when I tried lineage, found the answer on HTC forum,.
So avoid that from happening , before you make a backup, unlock all securities( pin, password, fingerprint) then make a backup, next time you restore your backup, it will boot without any issues.
ta for that. will try.
Good morning.
After almost 3 years with no problems with a XT907, I have again an issue with it (this time, my father's one). Again, I come to you requesting help.
It all started with all apps crashing over and over. With an old XT907 I have for emergencies, the common fix method is flashing VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml.zip with RSD Lite v6.1.5 and all solved.
I tried that method with my father unit, and when it started again, all process were still crashing. I thought it was still nothing (just a harder issue), and tried flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip, just deleting all his data, to fix it.
When the process ended, it turned on and it had still the same problem. In this point, I got worried the /system and /data partitions got locked
I re-started, went to stock Recovery, and wiped system and cache. Then, went to Fastboot a third time and tried again flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip. Guess what? Still the same problem
The phone turns on, but ALL apps keep crashing over and over. I can't even take an screenshot, as it immediately reboots.
Someone know what happened with it? And... how to fix this issue?
To make things worse
