then you need to downgrade to 4.2.2 and do the step and when you got imei back flash 4.4.2
if you are on new bootloader download 4.4.2 bootloader put it in 4.2.2 rom and flash and do the step and flash 4.4.2 stock again

First Flash Stock rom then flash IMEI . If you reflash rom then imei will again vanish. To prevent imei invalid problem you have to flash rom without flashing preloader.

You can get imei number back by following the instructions in this post .
NOTE : Type the imei number which is shown on the back side of your phone.
Once you get the imei number back and if you again reflash rom it will again wipe your imei number.
To avoid this problem you should uncheck the preloader file. Check in the attachment
Your imei number will not vanish.

Changing IMEI is illegal. But if you lose your IMEI no, then you need to manually set it. But the legal line here is narrow, you insert 1 digit wrong and you are breaking the law
becareful when you deal with IMEI number, it can be very dangerous, if something goes wrong you will be jailed. I dunno why would someone flash micromax a1 stock into spice or vice versa, it is a bad movie.
my phone is micromax canvas a1

No IMEI, ESN, MEID, and not recognize the chipset and phone.

Hi!, i have a LG G2 D805, that after to flash Lollipop Cloudy G2 3.3, my phone lose the IMEI, ESN, MEID.
I tried to rewrite with many programs this data but none conect. I tried with QPST, ESF Professional, CDMA Workshop, DFS CDMA Tool etc and all programs find the port connected, but when i want to read the phone, the connection drop. None program can to recognize that the thing conected is a phone, neither recognize the chipset.
In other words, the com port connect fine, but when i click in read phone information o any rad, says "the phone connection has be lose"
In not official SAT they tried with OctopusBox and had problems to connect again.
The phone works well , except at times when the PC not want to recognize the MTP mode , or the phone not save the hour change after restart.
Any method to recover IMEI and this data?.
I not have EFS backup.
Thanks!!

You will have to send it in for repair if you dont have a backup and a complete clean flash of the stock firmware doesnt work. Anything else is illegal depending on what country you live in.
I tried connect with clean and stock rom kdz of kitkat and nothing, not connect.
Did you try flashing your modem via twrp? I think your modem is corrupted.

[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.

>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

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......
Sent from my rooted, debloated stocKK kn0x0 SM-G900F
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

Has anybody found the solution? Efs professional gives me error " device connection lost" while using Qualcomm nv tools on s5.

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?

[SM-G901F] Soft-Brick after trying to enable all 4G and 3G bands using QPST

Hey Guys,
So I wanted to get better 3G and 4G Signal, So I used a Article I came across here https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I backed up NVRAM and added the additional bands as stated in this Article, and after writing the changes and a reboot on my phone, My phone bootloops and restarts as soon as it reaches the Lock Screen. This is disabling me to interface with the Serial Port again so I can change the settings back. Is there a way to stop the radio from being loaded so I can fix my phone?
Since ART takes twice as long to startup, I used a Android 4.4.4 Stock ROM and I was more successful, I had more time in the system itself but When I enabled RNDIS + DM + Modem on the Device, I only got a APQ8084 (0) Device which dosen't work with the restore and software programming (Last Time 3 Devices Showed Up APQ8084 + MDM* + No Phone (Samsung QC/Data Modem), But now I only get APQ8084 + No Phone + No Phone).
Any Ideas?

I have a SM-G900T and I was able to complete the procedure. In my case, it showed that all 3G/UMTS bands were already selected, but the bit field for the 4G was 0. My house gets 700MHz LTE, but it is Band 17, not Band 12, so I have not yet verified that the new band is enabled.
I used the "Qualcomm NV tools" including in EFS Professional to perform a backup of NVRAM before trying the procedure. I also had trouble changing the USB mode of the device. None of the secret codes for USB settings worked on my device (either with CM or stock), but I was able to use EFS professional to change the USB mode. On Win10 x64, adb and MTP were already working, but in modem/diagnostic mode, I was seeing an unknown Samsung/Android device. I reinstalled SAMSUNG_USB_Driver_for_Mobile_Phones v1.5.45.00 and restarted and voila, the serial port driver was installed.
If you successfully exposed the diagnostic virtual serial port, you should be able to use NV Tools in EFS to dump a backup of NVRAM before writing any values.

Thanks for the help but I just fixed it and now I have another problem, The phone boots but says that it needs a SIM Network Unlock Code, Should be simple enough to fix but Thank you. Even the steps you listed above may not have worked for me as the device was in a constant bootloop.
