Here is a sample log of an EFS backup :

[ONE Q&A, Help & Troubleshooting] drakester09:
Yes, I think it's efs1 and efs2

[ONE Q&A, Help & Troubleshooting] bud77:
Please try to read carefully what I posted, it's a PARTITION

Root browser will only show inside the data partition, not all of the partitions
[ONE Q&A, Help & Troubleshooting] simo.scorpion:
With my Samsung device I can see this partition....

Inviato dal mio GT-N5110
[ONE Q&A, Help & Troubleshooting] bud77:
This is just impossible

You might have been able to see the files used for EFS on that specific samsung phone, but not a partition other than the data partition
[ONE Q&A, Help & Troubleshooting] simo.scorpion:
I do not understand what you mean

this is my note 2 root directory, efs is present

this is opo, same app (root browser), but efs isn't present

so if efs is present on the opo why i can't see ?
[ONE Q&A, Help & Troubleshooting] KINGbabasula:
Because opo hasn't efs partition
[ONE Q&A, Help & Troubleshooting] simo.scorpion:
ALLELUJA !!!! this is the answer I wanted to hear, so why unofficial twrp have the efs backup ? it's an error ?
[ONE Q&A, Help & Troubleshooting] bud77:
No, OPO

HAS

an EFS

partition

Your screenshot show a

FOLDER

of an EFS, not a

PARTITION

If you don't understand the words, use a translator FFS

And TWRP can backup the

PARTITION

because it does exists, as I pasted a few posts back
[ONE Q&A, Help & Troubleshooting] simo.scorpion:
so, efs in opo is called modemst1 ? i try to search all partition with "partition info app" but efs don't exist.
[ONE Q&A, Help & Troubleshooting] bud77:
Your root browser app do not give access to partitions !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You only see the data partition, not the rest

What you see on your samsung is a folder, not a partition

There is no file on the EFS partition(it's a binary on it), the name you see is given by TWRP

Stop asking questions when you don't understand the answers, and just do the backup using TWRP

You truly needs a lot more knowledge of *NIX filesystem to understand anything I posted

Did 2.7.1.0 save the EFS? I've been using TWRP since I got the phone last week and some how TWRP did not restore my radio info. As of this moment I do not have a working o+ because of that. I'm stuck. I've fiddled around with a few devices with twrp and this is the first that has not restored the radio.
[ONE Q&A, Help & Troubleshooting] bud77:
Yes, 2.7.1.0 CAN save EFS. A normal backup does not include EFS

You have to manually make the backup

If you don't have any valid EFS backup, don't worry :

Just flash

all

stock images, it will rewrite radio
[ONE Q&A, Help & Troubleshooting] tdamocles:
I have flashbooted manually twice and used the toolkits with it ending in nothing. The phone will go into boot loops non-stop occassionally with no iemi# or baseband present.

I actually restored to a nandroid from 2.7.1.0 and 2.7.1.1. I always save all partitions. I thought TWRP was basically foolproof. I guess I'm a fool for thinking that. What really sucks is that I didn't save the nandroids off phone.
[ONE Q&A, Help & Troubleshooting] bud77:
Did you flash all the images ?

There should be a flash-all.bat included with stock images. Just run it

Open a separate thread in Q/A, I'm pretty sure someone had this issue
[ONE Q&A, Help & Troubleshooting] EddyOS:
Not with the CM11S factory images there isn't, you have to use fastboot flash -w cm-11.0-XNPH25R-bacon-signed-fastboot.zip or do each partition manually as per the guide in my signature

How can you manually add the EFS partition in TWRP in order to be backed-up ?
[ONE Q&A, Help & Troubleshooting] bud77:
I'm not sure it is possible

I just boot into twrp and manually backup

Then save the files on computer

You only need to backup once

[ONE Q&A, Help & Troubleshooting] RalphLauren:
The nandroid backup is done already weeks ago. No problem with this.

But as you said, this backup does not include the efs partition, that's why I start wondering about what options we have to safe it?

There are few Samsung tools which certainly do not work with OPO, so what is for us?

Any ideas ? Anyone?
[ONE Q&A, Help & Troubleshooting] tdamocles:
I have done it that way twice already and I still have no imei or baseband and it bootloops like no tomorrow. Any other ideas? I can get into fastboot no problem...it's the outcome that isn't working.

I did already and the thread died miserably. The link.
[ONE Q&A, Help & Troubleshooting] bud77:
How can you see if there is no IMEI or network if your phone bootloops ... ?

Bootloop means the phone reboots itself before entering android
[ONE Q&A, Help & Troubleshooting] tdamocles:
Because if I don't try to charge it, it doesn't bootloop. The second I put the charger on it....it bootloops and gets very hot. I'm afraid to charge it in fear of it exploding. The only time it doesn't bootloop is if I charge it on the pc(500ma) but that takes a long time.
[ONE Q&A, Help & Troubleshooting] bud77:
I'm not sure I understand everything here

My question was :"How do you know IMEI and network does not work ?"

And your answer is about bootloops and charging ... (And for the record, the reboot happens because the phone is too hot)

Also, what is the result of flashing the sotck images via fastboot ?
[ONE Q&A, Help & Troubleshooting] tdamocles:
First, it runs normal with occasional reboots when the charger is not on it thus allowing me to see that there is no imei.

Second, when I insert charger(over 500ma-when not overheating) it starts bootlooping endlessly. For the record, the phone is not hot when it starts bootlooping. It starts getting hot when it continues looping.

Finally, stock images does nothing but the same as above.....no imei, bootloops when charging with something greater than 500ma.
[ONE Q&A, Help & Troubleshooting] dictionary:
Having this exact same issue. Flashed the official AOSP. Didn't like it, restored my nandroid with TWRP, including the efs and modem. Boom, no signal. No amount of fastboot flashing does anything, and I get constant reboots. Yay me.
[ONE Q&A, Help & Troubleshooting] bud77:
Sounds like defective hardware to me

Try to contact OPO support for the EFS part, explaining the reboot thing altogether
[ONE Q&A, Help & Troubleshooting] dansou901:

You know what's wierd.....that's when I lost all my sh*t....It failed to install that official AOSP and I tried going back with a Trwp nandroid and then this stuff happened...

I just noticed that the aosp zip includes the radio...why? Isn't that usually left out on a rom install?
[ONE Q&A, Help & Troubleshooting] tdamocles:
Is the radio in the aosp rom different?
[ONE Q&A, Help & Troubleshooting] bud77:
Yes, they are different. That's why we're telling you to reflash CM's radio

---------- Post added at 10:50 AM ---------- Previous post was at 10:47 AM ----------

I'm at work now...did you try pulling the aosp zip apart to get the radio to flash by chance? I think it was in a folder named update firmware?
[ONE Q&A, Help & Troubleshooting] dictionary:
Tried flashing that, still no dice. The problem is /dev/block/mmcblk0p10 of=/sdcard/PARTITION_BKP/modemst1 and /dev/block/mmcblk0p11 of=/sdcard/PARTITION_BKP/modemst2. If I fastboot erase modemst1 and modemst2, I no longer get reboots, and WiFi works great. Data still doesn't work though. Not sure how else to restore the EFS. And before anyone asks, no I don't have a copy of it. Also, I know it's my fault for not copying it, just haven't had any devices really with this whole EFS nonsense, so was thinking if I have to completely wipe the device no big deal. Wasn't thinking about the EFS getting screwed up. So far not a word from OP or CM. What else is new.
[ONE Q&A, Help & Troubleshooting] rickyx32:
You guys are scaring the crap out of me, is there something I should be aware of when flashing on the OPO? I've been flashing and heavily modifying to my hearts delight on my Nexus 5. Whenever things got messy all I had to do was run the flash-all from the factory image... :(
[ONE Q&A, Help & Troubleshooting] dictionary:
Just make a backup of your efs and save it to your PC. That should solve that.
[ONE Q&A, Help & Troubleshooting] rickyx32:
Hmmm, on twrp all I see under what gets backed up is boot, system, data, and cache... Is the efs part in any of those? I did make a back up when I first got the OPO and it's on my desktop. How do you tell if you have the efs saved?

I believe it would, but any talk about using someone else's efs (imei etc) will get this thread locked. Shoot, if I could get a working efs to make my gsm work, I'd edit my original imei back, if that's the route OP or CM gave. Just don't like using this as only a WiFi device lol

I reset CM11S to complete stock including data wipe.

I then installed TWRP and used it to flash ColorOS. I tried to boot and for awhile and it didn't start so after that I factory reset and tried to boot again and it started with mobile data disable but a signal and when I toggled mobile data it worked perfectly.

2. factory reset using stock recovery

3. flash official twrp

4. flash the ColorOS that I linked earlier - http://xdaforums.com/showthread.php?t=2772627 (you can skip all the account setups if you want)

5. 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)

6. if you have data in ColorOS you are good to flash back to CM11S anyway you want

7. save yourself the headache in the future and backup your EFS

I prefer to do those commands manually, even though the toolkits are less hassle. That being said, if you're already on a ROM or have twrp, I don't think you need to go all the way back to stock. Is your WiFi working fine?

Ok, I was going to call it quits because it didn't work this way for me exactly. I wiped data, cache, and dalvik in advanced wipe and it did not work.

I tried again in this order.

1. Download the rom posted(ColorOS)

2. install or boot into TWRP(used the one with efs backup) and/or backup

3. Just wipe cache, dalvik, and install colorOS(dirty flash)

4. It will not boot......kinda loops....turn it off and go back to TWRP

5. Now factory reset.....and reboot

I don't hate them. Nor do I hold them responsible. Customer support wise though, I haven't heard a thing. I sent two tickets, no reply.

I have confirmation that someone that works at CM saw our issue, but again, no acknowledgement or even attempt to give advice.

I get that they are young, but they also are where they are because of the community, and their "connection" to the community. By not responding to issue at all, and going radio silent, it makes me lose faith. I'm not asking for them to send me a free device because of a goof. I'm just asking for a little guidance

Not through yet, but booted ColorOS and was not greeted by some FC, instead it asked for my SIM-PIN, and mobile data worked right away !

I still don't have WiFi / Bluetooth mac addresses, though...

Thanx for this, this is a huge step forward !

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 ?!

Sounds like you aren't doing full wipes. Also, are you comfortable using fastboot?
[ONE Q&A, Help & Troubleshooting] tdamocles:
Dictionary is probably going to tell you to fastboot erase modemst1 and modemst2.. I did.. It wouldn't hurt.. Try to dirty flash over a rom with colorOS and when it fails to reboot then go back into twrp and factory reset.

I originally had cm11s . .booted TWRP and wiped data, system, dalvik, and cache. Then i installed colorOS. It did not work. I started again. I re-installed cm11s. .This time i flashboot erased modemst1 and modemst2. Dirty flashed colorOS (wiped dalvik and cache before flashing). Let it boot. .it will not boot(just loop). Turn off and re-enter TWRP and factory reset. Reboot.
[ONE Q&A, Help & Troubleshooting] dictionary:
Correct. I had buggy WiFi and freezing until I erased those. Then they worked properly.
[ONE Q&A, Help & Troubleshooting] Yank555:
I've been into this long and deep, done that helped nothing, fastboot I know to use (how do you think I got back to CM11S, fastboot flashed factory images), and I know the difference between removing files and formating a partition, I can assure you that ;)

Thanx for the help, though, anything at this point is better than customer support.

JP.

PS: Formating modemst1 and 2 made no difference, that I had tries already even before opening my support ticket...
[ONE Q&A, Help & Troubleshooting] dictionary:
To be fair though, your original post says nothing about fastboot. You could have used a toolkit to go back to stock, like so many do. That said, sounds like you may have a different issue from those of us here. I probably fastboot flashed the cm11s x25 build. Everything worked fine except WiFi and data. Once I connected WiFi, phone would freeze and reboot constantly. If I went into airplane mode, it was fine. I reboot into fastboot, and erased the modem files. That got me a perfectly working device sans data. If that isn't working for you, then I'm curious what your issue is.
[ONE Q&A, Help & Troubleshooting] Yank555:
Not into toolkits, I make my own kernels, so I like hands on stuff :D

Definately sounds like my issue is different, indeed ... unfortunately for me.

I know about the modemst... partitions from the Note 3, so that I tried as well, no luck.

For me CM11S boots up to welcome screen and gives me a constant AudioFX FC, unusable.

On Slimkat or CM11 nightly I get to see the welcome screen for a few seconds then it reboots. ColorOS asks for my sim-pin, and let's me run the ROM fine with mobile data, though WiFi/BT have no mac addresses. Wiping modemst1/2 at that point made no difference...

Will have to wait for customer support and enjoy my Nexus 5 until they deem fit to get back to me.
