[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Hi all,

I have a weird problem that I can't seem to fix.

When my phone boots up it is stuck in factory mode (grey box, yellow writing) due to an EMPTY EFS folder.

I also have no lock screen and no power menu when I hold power button.

My IMEI is still fine, and my Baseband is fine. I can make calls, receive calls, use data and everything else is fine.

Is there a way to just fix my EFS folder?

I've found various threads on what to do if your Baseband is NULL and you have fake IMEI but mine are fine.

It's a weird issue, one that I really can't solve myself.

And no I have absolutely no back up of the EFS, if I did I could fix it.

I've tried flashing various stock firmware in Odin.

Formatted everything (Except EFS) and flashed.

Flashed firmware and .pit file for i9505.

The only thing I can run without any issues at all is Cyanogen Mod, if I flash this I have lockscreen, power menu and no grey box.

But go back to stock firmware and it all comes back again.

Any help would be greatly appreciated!

go to efs/imei folder, and make a file called "keystr" (without " ") (it is probably missing)

open "keystr" file and write "on" (without " " ),save. set permission of the file (all ticked).

or

using terminal emulator, type these commands

su
echo -n ON > /efs/imei/keystr
sync
reboot
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Thank you I'll try that.

I've put files in there before and they just get wiped after a reboot.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
My EFS folder is empty, so I have no imei folder .

created a folder efs/imei and made a new file called keystr. Open this in a text editor and typed on. saved file. (is that what you meant?)

Still no joy, No power menu and after reboot my EFS folder is again empty :(

EDIT: I just had a look on my other i9505 and the keystr file is actually in a folder called FactoryApp, not imei???

Anyway, no matter what I put into this EFS folder it doesn't survive a reboot :(
[Galaxy S 4 Q&A, Help & Troubleshooting] samersh72:

[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
No luck.

Same old story, what ever I do in the EFS folder doesn't survive the reboot.
[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Try removing write permissions for all users. So when creating the file type on the terminal (before sync command):

chmod 555 *thefilewhichnameifoegot*

Hope this can solve your issue ;)
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Thank you for your suggestion.

I tried typing : chmod 555 /efs/imei/keystr

but still the same thing, after a reboot my EFS folder is empty :(

The thing is, I'm not even getting a straight answer out of Samsung either.

I've rang the service centre and said. " I think my EFS partition is corrupt on my S4. When I look in the EFS folder on the root of the device It's empty"

They have no idea what I'm talking about! I mean, come on! They work in a service centre for Samsung!

all they say is I need to send it in for assessment and pay $45 for them to check it. If it's software related then they will send phone back but If it's hardware then they could charge $300-$400 .

I'm not sure what it is, I mean it's software related but in order to fix it I think they need to solder up the main board to a SPT box (I think that's right) so that could be considered a hardware fix??

I just want to know if it's worth me sending it in lol
[Galaxy S 4 Q&A, Help & Troubleshooting] samersh72:
type these commands in terminal emulator, and i think you will be ok

su

I don't think those commands will work though as there is nothing in efs folder........

EDIT: As I thought "no such file or directory"
[Galaxy S 4 Q&A, Help & Troubleshooting] ckitching:
Perhaps a dumb question, but have you checked to make sure the EFS partition is being mounted? If not, then all these write attempts are going to the ramdisk, which obviously doesn't survive a reboot.
[Galaxy S 4 Q&A, Help & Troubleshooting] Lucas_Skyline:

SIR YOU JUST SAVED MY LIFE. NO MORE ANNOYING YELLOW TRANSPARENT BOX.

I'll thank you later, running out of thanks
[Galaxy S 4 Q&A, Help & Troubleshooting] ckitching:
Well, if it's not mounting and you didn't take a backup of the files on the EFS partition before modifying your phone, then I'd suggest starting by getting a dump of the partition, and keeping that somewhere safe. After that's done, you can try running an e2fsck on the partition and hope that this is enough to bring things back.

Backing up your /efs was usually the first step in modifying your phone in the G.Nex and SGS2 days because the device-specific data can be difficult to recover, but it seems it's not done as commonly these days.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Yeah that's my problem, I can't mount my EFS.

Can you talk me through getting a dump of the EFS partition please?

Sorry total noob here!

Do you know what block the EFS partition is in so I can run a e2fsck?

I was wondering if formatting EFS via CWM recovery might help?

As I don't know what I'm doing and I have no backup I've left it well alone.

Could I backup the EFS partition from another i9505 and try to restore it on this phone?
[Galaxy S 4 Q&A, Help & Troubleshooting] ckitching:
Do not just format the EFS partition if you do not have a copy of the files that belong in there. Those files are device specific, and include things like your bluetooth and WiFi MAC address, etc.

To create a backup of your (currently damaged) efs partition, run these from either a terminal window or an adb shell session:

su
dd if=/dev/block/platform/msm_sdcc.1/by-name/efs of=/sdcard/efs-backup.img

This should create a file named efs-backup.img on internal storage (mine is 14,286,848 bytes long on my i337M, but I don't know if all S4s have the same partition sizes so yours may be smaller or larger), that you should back up on your computer before continuing.

To try and run a repair, first run "mount | grep efs" (without the double quotes) on your device and make sure a line similar to this mentioning efs does

not

appear:

/dev/block/platform/msm_sdcc.1/by-name/efs [B][U]/efs[/U][/B] ext4 rw,seclabel,nosuid,nodev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,errors=panic,data=ordered 0 0

If the volume is not mounted (does not appear) at this point, you should be clear to run an fsck on the partition:

su
e2fsck -fp /dev/block/platform/msm_sdcc.1/by-name/efs

You may have to run the e2fsck multiple times if it finds errors. Eventually, it should come up clean and you can finish off by syncing and rebooting the device:

sync
reboot

No guarantee that this will work, though. If the filesystem corruption is bad enough that it can't be automatically fixed at startup, files may already be lost on that partition. If it does work, be sure to take another backup, either through recovery, or by running the "dd" command again.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Thank you for such detailed instructions, I really appreciate it!

I'll try it and see what happens.

You say not to format efs as I may lose files but aren't they already lost if the folder is empty?

Is there anyway of getting these device specific files back again without backup?
[Galaxy S 4 Q&A, Help & Troubleshooting] Lucas_Skyline:
I think, I'm not completely sure, if you still have IMEI and can make calls, your efs is not empty, it is only not mounted, so you can not see the files.

Probably following those steps, you'll be able to have the backup of the files.

If you don't, I think the only way to have the files back is sending the device to Samsung.

I already returned my S4 to Amazon, let's see if they return my money or not. If they don't, I'll try to make those steps also.

Thanks!
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
I tried your advice and came up with this message:

The superblock could not be read or does not describe a correct ext2 filesytem. If the device is valid and it really contains an ext2 file system (and not swap or ufs or something else) then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>

Now I'm a noob and have no idea what all that means, might as well be Japanese to me.

Could you maybe help me from here?

Or is it all over rover and off to our friends at Samsung ?
[Galaxy S 4 Q&A, Help & Troubleshooting] ckitching:
If the volume is that unrecognizable to the repair tools, you may just have to send it to Samsung.

[Shield Q&A] evobunny:
Anyone having charging issue. I ran my shield battery down when I first got it. Then I plug it in to charger. Its been charging over 8 hours and still not at 100 percent. took it off charge at 80 percent. No way it should take this long. I read on reviews it took like 4 to 5 hours.
[Shield Q&A] agrabren:
You used the charger that it came with? And you're not playing games the entire time it's charging, right?
[Shield Q&A] evobunny:
yes I use charger that came with it. and it was charging over night when I was sleeping.
[Shield Q&A] agrabren:
That sounds really odd. What does the battery usage say for the device? Was it awake the whole time? Does it think it was charging all night?
[Shield Q&A] Evo_Shift:
I feel like that has happened on my nexus 7 before. I bet it is an android thing. I would try again and see if it acts up a second time.
[Shield Q&A] evobunny:
when I was charging, i close the screen. so it went to sleep. I dont know how you can tell if it think it was charging all night. I went to battery info and its said 13.6 hours on battery. and 48 percent of that was screen usage. rest was on game and apps.
[Shield Q&A] agrabren:
If you go into the "Battery Info" and touch on the graph area, it'll show you below some bars of time spent on different functions (like charging)
[Shield Q&A] oushidian:
1. Sometimes the battery indicator on Android can take a while to figure out your battery. It might drop 5 percent in ten minutes then take an hour to drop 5 more.

2. The vent area on my Shield seems warmer than the surrounding plastic even when in sleep for a while, so it may be drawing more power than is charging. Just try turning it off and charging it.
[Shield Q&A] agrabren:
Which vent area? Front or back? Because batteries do warm up when you charge them, and those are some big batteries (and a full 2 amp charge)
[Shield Q&A] oushidian:
The smooth part on the bottom back with the model number, FCC, etc. And it's not when I'm charging but when the lid is closed. If I manually power it down then the warm goes away.
[Shield Q&A] elitecmdr666:
i never recommend running your device down when it comes straight out the box. usually i tell people to just fully charge the device first before running it dry therefore it can register the full battery, personally i would not leave a device connected over night just for the simple fact that it can be one in a million that the device might get screwed over a long period of time.

it be nice to know if the problem is fixed or not and what you did just in case others run into this same problem.
[Shield Q&A] s0me guy:
ive had no charging issues yet. batts do tend to get nice and warm tho.

but for what its worth i just noticed that im still getting notification sounds from my Shield even tho the lid is closed. so maybe its some kind of hybrid sleep and if you have some rogue app pulling a ton of CPU cycles & its not going into full sleep so its taking longer to charge?

just some food for thought on your issue
[Shield Q&A] agrabren:
Like most Android devices, the device goes to "sleep". Unless you power it off, it still handles notifications, and it still talks on WiFi. But it should consume very little power.
[Shield Q&A] SixSixSevenSeven:
Modern devices use LiPi or Li-ion batteries, these explode when overcharged (seriously, youtube search overcharge lipo). As a result all devices sold with this kind of battery have charge monitoring tools and will disconnect the battery from the charging circuit when full, also they should then run purely from the mains power when the battery is full rather than running on the battery again (they don't like the repeat connect/disconnect effect that would lead to). End result, can't overcharge it.

The heat on mains power tends to be from the voltage regulator. These devices don't run on 5V power like comes from the charger. They tend to use a combo of switch mode and linear regulators to drop the 5V to 3.3V for the CPU and peripherals (3.3 is most common at any rate). Linear regulators in particular get quite warm. Switch mode regulators don't get so warm but don't give a clean output the CPU will run nicely on, they have the odd drop or spike which would either reset or fry the CPU, so generally what happens is the switch mode reg drops a large chunk of the voltage and then feeds it into a linear reg to drop the rest of the way (*the less voltage a linear reg has to drop the less heat it produces). From 5V to 3.3V it is most likely going to be purely a linear regulator, with the CPU and screen drawing at least 1A of current and a 1.7V drop that would equate to 1.7W of heat produced, not much, but enough that if you were to put your finger on the bare regulator chip it would come away red, hold it there long enough and it would be somewhat like those competitions kids have over who can keep their hand on the hot radiator longest :P That is the main reason they will get hot.

The batteries in these devices are usually 3.7V, that would need a separate regulator from above, and another regulator would still be needed to go from 3.7 > 3.3. 3.7>3.3 would not get so warm. 5>3.7 would still be warm as above.

Never fully drain a LiPo. Gets too low and you damage the cell ir-repairably. When the device claims it is at 0% charge and shuts off is usually closer to 10-20% charge. But that is still considered too low by some people. General advice if you want to prolong the lifetime of your battery is to turn the device off and charge it when it reports somewhere around 5-10% charge.

Batteries do get warm while charging. But my bet is that the voltage regulators would be far more significant heat producers.
[Shield Q&A] s0me guy:
good to know. :good: i didnt think closing the lid was the same as pushing the power button on my phone to turn the screen off.

but the OP's problems still might be "sleep" related.

prime example my SGS3 batt life started to tank after the 1st VZW JB update. it took twice as long to charge & would never "sleep" (cuz of the OS not a app) but since the Tegra 4 is a much higher profile chip it could suck a bit more juice if its not being aloud to fully sleep, for whatever reason.

like you said tho, looking at the battery stats could easily tell us if this is the issue.
