[Q] Accessing Diagnostic Menu in 4.4.2 - Galaxy S 4 Q&A, Help & Troubleshooting

I've been trying to access the diagnostic menu (sometimes called service mode) on my S4 which has an unknown imei so I can try and rebuild it but all I ever get is a blank screen. I've tried every code I can find but the blank screen is as far as I get.
Am I missing something obvious?

[Q] Damaged EFS, no backup - how to repair S5 with NULL IMEI?

Hi,
I have a problem with my S5. After flashing a custom ROM I found out that my IMEI is null, and so the EFS is corrupted. I tried to restore it from backup only to find out that I have deleted the backup
What can I do now? I anything? Would restoring EFS from another S5 (with damaged mainboard) could be a solution?
Generally everything works except of phone modem, I have got IMEI written - is there maybe a method to set the IMEI without EFS or a method to create EFS? I already tried sam IMEI changers, but I found out that they only do this on the application level - apps will be able to read different IMEI for licensing, but phone still sees NULL IMEI.
You can't restore EFS from another S5 coz it'll brick your device.

Thanks for answer
So what can I do?
Found sth like this:
Never tried coz never lost IMEI
In the dialer, type- *#197328640# or *#*#197328640#*#*
>You will be prompted into the Command mode, provided On the screen, Select on Common, normally option 6
> Now Select (FTM) Option 1
>FTM is for debugging and testing., (Field Test Mode)
>If (FTM) is on, you will have to turn this OFF
>As soon as you turned this off your NULL or altered IMEI number will be restored
>(Important) Without leaving the Command screen, press the Menu key, the button that’s found left of the Home button.
> Select Key input and enter option 2. In this case, you want to turn it off
>Wait for a minute. This will turn your FTM OFF
> Remove your battery and SIM card for two minutes
>Place your battery in your phone, (important) do not place your SIM card in.
> When the phone is booted, enter the command mode again dial – *#197328640#
>Select the Debug Screen, normally option 1
>After that, choice phone control, option eight
>Click on nas control, option 3
>Afterwards, click “RRC (HSDPA), option 5
>To Fix not registered on network or Null IMEI #, click RRC revision, option 2.
>Choose the released of your phone, here we will choose option 5 (HSDPA only)
>Final step to fix Null IMEI not registered on a network for Samsung Galaxy is to turn off your phone and insert your Sim card
or
>Insert your Sim card, afterwards reboot your phone
Thanks - are you sure about this bricking device?
I already tried this numbers but it always says "No Network", The only instruction that I found was to use *#0011# and it goes into the Service Menu, but it doesn't look like that described. There is something called NVM restore, but it doesn't do anything with IMEI
I am gonnna post screenshots at evening.

Yes I'm sure about bricking. EFS partition on your phone is made for ONLY YOUR PHONE. This is sth like restoring TA Partition on xperia devices. When you flash ta from another xperia, you brick device
Tapatalked from SM-G900F
I read someone saying they had successfully restored a backed up EFS partition from an identical model S5 to another, and it worked
The problem I can see, is if the original gets blocked by the carrier, chances are so will the clone
Not sure about network issues having two identical devices on the same network at the same time, both making calls, might end up like an IP conflict
Pretty sure that transferring IMEI from one device to another is against the law too......

Yes, I also know that is it against the law, but I have a complete phone with broker mainboard (so even the IMEI is written on the back), and I would like to use this opportunity to copy the IMEI from old (broken) mainboard to the new one. It even looks better than the situation when I have got and old case with written IMEI that doesn't correspond to the IMEI on the new mainboard.
The mainboard is broken that way, that there is short-circuit somewhere and the CPU is constantly using power and it get's really hot, so it use useless.
I am trying to flash EFS, let's see what is gonna to happen

1. Tried flashing EFS = nothing happened
2. Tried flashing EFS + Modem + ModemST1 + ModemST2 = nothing happened
3. Restored android to STOCK
I can't get into the service menu.
The only Service menu that I can get into is this one, but there isn't any fixing IMEI/NVRAM option
Code:
*#0011#
Menu > Back
Menu > keyInput "Q"
Menu > keyInput "0000"
Wait for few seconds

Hi,
you have 2 options
1. Use Samsung Kies which will repair you efs
2. Flash with Odin the official rom 5.0
If you install another efs, the data installed may be not work, even if it is same model. In S5, nothing to do with the IMEI
You can also root the phone and with adb commands, erase all the efs
you can also use Z3X tools
Hi,
Thanks - some new ideas
So if I understand you correctly, I have 3 options:
1. Use Samsung Kies which will repair you efs - how to repair EFS with Samsung Kies?
2. Flash with Odin the official rom 5.0 -> I tried flashing oryginal 4.4 and it didn't helped. Should flashing 5.0 help?
3. You can also root the phone and with adb commands, erase all the efs - What will erasing EFS will give me? Shouldn't I have EFS partition with some data?
you can also use Z3X tools -> ok... I am gonna figure this out, 'cause I don't know it yet

J5 prime [SM-G570F] - signal issue on secure startup

Hi Everyone,
I've encountered an issue with the secure startup feature. On boot after providing the start up pin, phone take a moment showing a unlocking animation and then load to the home screen. The problem starts after that with no signals and unable to access mobile networks option (says insert sim though the sims are identified at the sim manager). I've done restarts but no use, then check the IMEI codes and it was unavailable. I thought the EFS folder is surely corrupted and I need it to give it to service. However, after several tests and finally disabling the secure startup option got the phone back to it's normal working condition. (Please note that I've not done a factory restore yet) Does anyone else have the same issue? is it a bug?

i9502 (S4 duos) enable CP logging / enable diag mode

Hello,
I barely post anything as there is a huge amount of documentation on this forum, but I am really stuck at this and have no clue how to solve it.
I have two i9502 phones:
- one with good IMEIs and thus, working GSM, but the sensors are not working (hardware failure - sensorhub test fail + all sensors from the *#0*# menu are dead)
- one with good sensors, but one of the IMEI is null, thus GSM is not working
I am tying to clone the one with good IMEIs over the one with bad IMEIs. I have previously done this with success, but for the S4 Active model (i9525).
To do this, I need to use QPST or EFS Professional (awesome software btw) with the phone running in diag mode.
When I enable "DM+Modem+ADB" from the *#0808# menu I get "USB device not recognized" on my PC, a problem usually resolved by "Enable CP logging" from the original recovery.
The problem with this model is that "Enable CP logging" option is missing from the recovery.
Also, codes like ##DMMODE# or ##DIAG# have no effect and there is no relevant option in the service menu (*#0011#) or diag config menu (*#9090#).
Things I've tried so far:
- directly backup/restore EFS partitions using TWRP or EFS Professional
result: fail, I had both IMEIs null.
reason: Encrypted File System partitions are encrypted using the phone's certificate/key. This means the EFS backup only makes sense for the original phone.
- downgrade to android 4.4.2
result: fail, recovery menus and secret menu codes behave exactly the same.
- flash a recovery from i9500 to get the "enable CP logging"
result: fail: when I enable the option, the phone restarts and PC still not recognizes the device. This was the closest I ever got to solve this.
- downgrade to android 4.3
result: fail, cannot flash, odin gives error and the phone says something like "firmware revision 2, phone revision 3" (incompatible hardware revisions?)
Does anyone know how to enable diag mode for this model?
Important to mention that I do not have any kind of service box.
Things I am thinking of trying:
- flash MIUI and see from there. I doubt a ported rom could do anything about this.
- cook android 4.3 using dsixda's Android Kitchen, and flash using a custom recovery. I doubt this will work also. Expecting a brick
Thanks.
You ever figure out how to do this?

ServiceMode Access

Has anyone else tried messing around with service mode on stock firmware?
I have a g950u from T-Mobile and I accessed it by entering (+30012012732+ into the calculator then entering *#197328640#
other codes work but I can't get to a menu with them

Factory reset has me stuck on "Checking for updates" - Can I re-flash?

Hi all,
:crying: - Looking for a way to get my Mi Note 2 back to life!
This device has never been unlocked or ROMed before (although it has been re-flashed successfully via Xiaomi's own pushed updates).
It is running MIUI 10.0.something (cannot access menus to verify exact).
The problem
----------------
I did a standard factory reset on the phone.
Once restarted, it takes you through the normal setup screens such as 'language', 'region', 'wifi network' after which I am given the option to select "copy your data from an old phone" or "set up as new", no matter which I select, my phone goes to the next screen which shows "Checking for updates". Here it stays - endlessly...
What have I tried?
----------------------
I have tried a different wifi network but it does the same.
I have also tried selecting "copy your data" instead of "set up as new" but it does the same.
Thoughts
------------
I thought I would try to install a new stock ROM to see if that would fix the issue. However, in order to unlock with the Mi bootloader unlock tool (and then use their flashing tool), apparently to do this, I need to enable something under developer options - clearly impossible when I cannot get to any android menus.
The phone *can* be re-started into the fastboot screen but does this help me at all?
On the MIUI website I noticed the following in the tips and tutorials forum: How to install a MIUI update without unlocking the bootloader: https://en.miui.com/thread-3852597-1-1.html
The above got me slightly excited before I realised that I have no way to place a ROM into the ‘downloaded_rom’ folder in the internal storage of my device (as the article instructs). Note that the reason for this (on my phone at least) is that although a Windows explorer window does open when I connect the phone to my laptop, it is empty (i.e. you cannot see any files/folders in it). BTW - I know what causes that specific issue as that bug was present in the device ages ago - basically, the phone seems to default to be in USB charge mode and in order to see the folders in Windows Explorer, you have to go into developer options and manually change the USB mode and then change it back to MTP mode. Once that is done, you can see the files/folder structures. However, I cannot get to any developer options as I cannot get to Settings at all.
What can I do?
------------------
So my burning question is this: How can I re-ROM this theoretically 'working' device, given the above constraints?
Is there any way to do anything while the phone is in the fastboot mode perhaps?
Is there some method maybe used to recover a bricked device that I could employ here?
Thank you for any help offered!
Cheers!
