Phones IMEI changed without even touching it

I have this problem - my G800F changed it's IMEI to 350695200123951. When that happened I had not touched it (no root, no nothing) at evening I still was able to make calls, but later that night it showed 'not registered on network'. I have tried factory reset, reinstalling the firmware using Kies, then I used odin, tried to make EFS backup and restore, but so far I haven't had any success. So I thought that some of you brilliant minds could help me, maybe there is a way to change the IMEI in efs backup file? The only strange thing that happened to my phone couple of days before this happened is that some random number from Ukraine called me, but for obvious reasons I did not answer it nor did I call it back. So now I'm stuck using my fathers old HTC Wildfire S, I really hope that you could help me, because I want my phone back.

SOS
Sorry no answer from me but exactly the same thing with my S5 mini g800F last week (end Sept), with exactly the same false IMEI, and I think I have now tried everything. No luck. Not the Ukraine phone call though!
Cannot get into "engineermode" which may have been a way to fix this. I loaded a new firmware, still nothing. ANY help will be appreciated but please nothing that asks me to add a "secret code" as the phone does not respond to those. I'm not an expert but got desperate enough to try my hand at a terminal emulator, it did not work. Stopped short of using SDK as the download is huge. Firmware now loaded is android 4.4.2 build number KOT49H.G800FXXU1AOG2. Heeeeelp anybody! The vendor is of no use either, just mumbling "this is a very strange thing, where did you get the phone....." (bought from the guy asking!!)

Warranty service restored the original IMEI

Just couple of days ago got my phone back from warranty and they fixed it (thought they wouldn't since it was rooted), so I would suggest doing the same thing. At the warranty center I had to explain my problem for about 30 minutes, because they believed that phone couldn't change its IMEI. Also you could try other service centers, because some of them said that they could fix this problem for about 30-50 EUR. I believe the only thing that could help otherwise is something like the z3x box, but it would be more expensive as it costs 100+ USD.

If you download the original stock firmware you can flash the IMEI number back to the phone

:S
No solution has been under warranty , the pochaine time to think about backup your EMEI

Yes yes
there is a backup somewhere between all my external hard drives, memory sticks, cloud servers... And i can't find it, too long ago and too many passwords!! But, no use telling me now to make a "pochaine" backup. I will try the reflash to older version suggestion, and see whether that gives me access to the required features. If not, it is the mountain to climb, of getting to the samsung "support" to tinker with the phone. Glad you you are sorted sunciks. A person from xda did contact me, so lets see if that bears fruit.

A back up of your phone? I would suggest just making a new back up because it's less time consuming.

You are going to have to be patient with an old person here. Making a backup of the current situation? Will it not just copy the existing false IMEI and replace on restore? Please be specific, step by step, as you would for a kid. Regards

Nope it shouldn't. The IMEI number is installed with the firmware. So if you back it up and factory reset, it should fix it.

If factory reseting doesn't work, then I suggest flashing the firmware manually.

OK I have tried this before, but just tried again. Does not work or I'm not doing it correctly.

What's the model number?

Meaning tried to backup and factory reset. Now in process of manual flashing (via Kies). Previously found that Kies would download for an hour and then say "unexpected error...." so have not used it in more than two years. Anyway here we go again.
Model is SD-G800F [samsung galaxy s5 mini]

No, I mean downloading the firmware upgrade. It will download the new files but not install. This was long ago. Right now I get to tools to upgrade and initialise and get the message "does not support initializing" I give up!

No don't give up, just download the firmware and flash it with ODIN. If you need my to explain that, leave me an email and I'll send you the instructions.

What you propose was the second thing I did. The first was doing a factory reset with the older version of the firmware (what the phone came out with). Neither steps worked. The firmware I flashed was (Build number) KOT49H.G800FXXU1AOG2. Which btw Kies indicates as the latest version.

Bootloader unlock theory 2

I possibly found that the lg g4 can connect a serial console when in fast-boot and android with limited access, and that the boot-loader is based on little kernel
codeaurora.org/blogs/little-kernel-based-android-bootloader
It may be possible to connect uart via serial and map out how the bootrom loads the sbl and (aboot (bootloader))and possibly find a way to unlock the boot-loader
newandroidbook.com/Articles/aboot.html
so far acessing fastboot with a nuked laf partition only specific fastboot commands work. can not get oem-id or reboot/continue via fastboot
console=
/dev/tty
/dev/ttyHS0
/dev/ttyHSL0
/dev/ttyHSL1

Try posting this in here: http://forum.xda-developers.com/g4/help/unlock-technical-steps-to-make-unlocked-t3165391
Or even the general G4 forum; the audience appears bigger and you'll probably be able to get more brains taking a look at this!
It's quite interesting.

Dude, I was literally coming here to see if anyone had tried anything like USB serial console the way you'd do with like a raspberry pi or a more recent thin client and found this thread with the search feature.
I'm glad to see that it does, in fact, work. I was about to pitch the theory, but it seems you've not only arrived at the same theory, but have tried it yourself. +thanks for posting the results dude. Much appreciated. Hopefully this will lead to some kind of progress otherwise I'm just going to use an upgrade to get something else and sell my G4. I'm really getting tired of the total lack of ROMs. This isn't 2008 where only a couple carriers have Android phones and the developer base is tiny. What company thinks it's SMART to create only one model that can have the bootloader unlocked and then NOT make that model available on all carriers at the off-contract price?!

I'm guessing there is no way to edit the LK, and implement these changes to re enable fastboot commands without it throwing some type of error due to the fact of it not being signed? -
To selectively enable any fastbootcommand on user/production build, add the command as shown below:
File: bootable/bootloader/lk/app/aboot/aboot.c
Function: void aboot_fastboot_register_commands(void)
structfastboot_cmd_desccmd_list[] = {
/* By default the enabled list is empty. */
{““, NULL},
/* move commands enclosed within the below ifndefto here
* if they need to be enabled in user build.
*/
#ifndefDISABLE_FASTBOOT_CMDS
/* Register the following commands only for non-user builds */
{“flash:”, cmd_flash},
{“erase:”, cmd_erase},
{“boot”, cmd_boot},
{“continue”, cmd_continue},
{“reboot”, cmd_reboot},
{“reboot-bootloader”, cmd_reboot_bootloader},
{“oemunlock”, cmd_oem_unlock},
{“oemlock”, cmd_oem_lock},
{“oemverified”, cmd_oem_verified},

only prob is still oh never mind i do have a twrp lol i forgot kernals wouldnt be same we would need i thing the debug bootloader for ls991 which i actally read the other day on something trying to find us one.
in theory a debug or engineering bl should overite a qfuse in a way kinda thing device model specific but firmware versions usually dont matter or at least the few ive messed with on samsungs.
im in no way a dev but if someone could possibly mod one of the debug bls for us then yes may be possible because if im not mistaken the v20s are locked as tight as ours arent they`

Can this work via lg flash tool to convert say a ls991 to h811? Is there any special ools needed like octopus box?

I dont think we can cross flash to811. Ive tried askin that one may be possible with box but doibtfull
And sprint wont unlock bl. Only lg can. They would have to basicly give u the signature to sign ure own images. Unless they offer unlock when nougats released

Relock Bootloader H811?

I had rooted my H811 but ive had problems with my phone contacted T-Mobile and they are going to replace my phone but i had flashed the 81110n kdz i got no unlocked bootloader warning but once it updated to 20i the warning came back is there any way to relock the bootloader or pull the warning help plz

Doubt it will even matter

Please help....

To lock the bootloader back is as simple as unlocking it, just follow the next steps and you'll be good to go :
Code:
adb reboot bootloader [b] (this reboots to bootloader)[/b]
fastboot oem lock[B] (this wipes all data)[/B]
P.S. This process may or will erase ALL DATA from Internal Storage.

I have managed to get it to reboot temporarily by putting it in the fridge for like 15 mins. But how do I get to the screen above so I can remove twrp and relock the bootloader?

So I kept trying to do the freezer trick over and over again until I noticed that it actually had to be in the freezer the 20 mins just to start!! If it did not it would not boot at all. It was not a battery problem, it just stopped unless it was cold. I took a chance on sending it in since it was warrantied still, and crossed my fingers that they would not do the freezer trick at the factory. They did not and a few days later I checked and it was in their repair qwe. Keeping my fingers crossed until I saw that the resolution was "Replace motherboard" Reason "bent motherboard". I know the bent mobo was BS. But hey what ever it took right? A few days later it was in the mail and my son has been using it perfectly well since then with that same battery and another he purchased! They did take the protective glass screen saver off for some reason. So Bonus a practically new phone and I still got some warranty left until Oct of this year!

great at least you have a working phone, thats what you paid for anyways..
did you unlocked bootloader? i wouldd like to unlock it. but same reason warranty... so i was thinking since i saw this post that it can be relocked but theres no video of it... like unlock it, then if i get bootloop. flash the modded KDZ relock it, then flash stock and send it for repairs... could it be done?

I bought it unlocked, it turned out to be one of the models with the bad motherboard. The previous owner directed me to here so I could re-lock the boot loader. I got to the window several times but it would not stay long enough for me to try re-locking it. That's why it was nice that the phone's mobo was bad enough that it just stopped booting up! I took a chance. If it had booted and they would have seen the un-locked BL they could have told me tough luck. But I have read in many forums that LG is pretty good about this issue with the bad models. So it's a roll of the dice and lucky for me either the phone did not boot up for the Tech who handled my phone, or he saw what was going on and went ahead and switched out the mobo despite seeing the first screen screaming "unlocked bootloader!"

So it's a roll of the dice and lucky for me either the phone did not boot up for the Tech who handled my phone, or he saw what was going on and went ahead and switched out the mobo despite seeing the first screen screaming "unlocked bootloader!"

you were lucky only a few of them have been repair after unlocked bootloader..:good:
i have heard some complaint from other users that theirs were denied. not unlocked, but he assumes they LG tought it was unlocked because he says that when you request unlock.bin you must place your imei or serial number so they have it on record....
so you planing on unlocking this ?? HAHA if you do. i would like to see someone post a video or relocking and that it works..

No I will not be unlocking it. My son has the phone and wants to keep it locked in case. Like I said he is still under warranty.

yeah makes sense, better have it under warranty.

To lock the bootloader back is as simple as unlocking it, just follow the next steps and you'll be good to go :
Code:
adb reboot bootloader [b] (this reboots to bootloader)[/b]
fastboot oem lock[B] (this wipes all data)[/B]
P.S. This process may or will erase ALL DATA from Internal Storage.

This process will remove my all data like Images, Video, contacts etc.... or will wipe out my complete phone including OS files??

SM-T817V Firmware nowhere to be found?

I work with a private computer repair company and we often refurbish devices, like older computers and monitors. I'm attempting to refurbish an older Samsung Galaxy S2 tablet with Verizon a customer brought in, but FRP is preventing our factory reset. We've attempted calling and emailing the customer for that login information but they aren't responding, so we need to reflash the firmware. Is there anywhere we can get SM-T817V firmware? Also, if we can't find that specific firmware, i there any other version of firmware we can put on it that won't cause too many issues? We don't absolutely need LTE on the tablet, but keeping it would be a huge plus.

It depends on the reason frp has kicked in. Does download mode state any of the partitions are custom or is the device status official?

FRP kicked in I can only assume because the original owner didn't properly reset the device. The current owner came in and stated it was like that when he bought it. When opening in download mode, it does state the device status as official.

You either need the combo firmware or an eng boot. Neither of which seem to be available without payment.
The other option is to try one of the FRP bypass tricks.

The video you recommended is in Spanish, which isn't necessarily a problem. The problem is the tool he says to use doesn't work anymore (the download link is broken, taken down by MediaFire's TOS). If you've got any other suggestions, I'd be glad to consider them.

Like I say I can't recommend one, just got to try them. However the methods are pretty generic and I have used the method below successfully on a completely different device:
https://m.youtube.com/watch?v=a-A-poRZPzY

That one doesn't work either. I'm currently running the device on Android 7.0 and I've found a way to get into Settings. All I need to do is find a way to get into developer options and I'm golden. But, I can't do that. If anyone can help find a way to do that, it'd be wonderful.

[Given up] Semi dead Lake

Hi,
I've just semi killed my XT1965-2.
I've unlocked Bootloader with
Code:
fastboot oem unlock [unlock_code]
and flashed Magisk with
Code:
fastboot flash boot magisk_patched.img
and worked fine. But, some months later, I've decided to remove Magisk and at the same time downgrade Android from 10 to 9.
Following the commands listed in this site, after it booted into Google Wizard, I thought it worked and then I rebooted to fastboot again and relocked the Bootloader with
Code:
fastboot oem lock
, after that I realized that the command for flashing the wi-fi module was missing.
So what happened was that I have a phone that boots up but won't find any wi-fi network or mobile data to connect and it won't bypass as I have my Google Account activate no the device.
In searchs I've found this and, as I cannot flash any partition as I have my Bootloader locked, I've thought I could boot via
Code:
fastboot boot boot.img
and try to bypass the Google Wizard via adb, but no success.
The question is: is there another way a could use to access the OS to allow unlock bootloader again?
Via command that I'm missing or even adding the missing bluetooth modulo to the boot.img and making it available to the device and I can access the internet and log in the my account.
I hope I'm being clear enough.
Thanks in advance!

Hi,
first of all I'd like to thank for the answer.
Using LMSA was my fist try to rescue the phone. It won't work, I get some kind of error saying I'm choosing the wrong model but I'm not.
I also tryed to use Motorola's RSD with no success.
Because of this I was looking for another solution.
Any way, thanks again!

Just out of curiosity, why in the world would you relock your bootloader. That serves absolutely no purpose whatsoever, and as you have found out, can cause a myriad of issues. There is nothing to be gained by relocking the bootloader. PERIOD!

Well, so your phone boots and everything, you only need to flash a newer build, go to https://mirrors.lolinet.com/firmware/moto/lake/, and find the newest build for your variant and flash it manually, after that you can boot your phone and unlock the bootloader again to do the downgrade correctly

Okay, I didn't take it to the next step and offer him a solution. You are correct it was very inconsiderate. But at the same time, what I said is true. It appeared that it was when he tried relocking his boot loader that he ran into a problem. And there is no reason to relock the bootloader.

Unfortunately I had to find out in the worse way. But I really didn't need to keep the bootloader unlocked as some banking apps just won't work this way and I needed to root for a unique propurse that was to access a sqlite database file.

My device is Motorola Moto G7 Plus, XT1965-2.
I really, really appreciate your help.
I put myself at disposal for further information.
Thanks a lot.
PS: I've found some tools called Android Image Kitchen that could unpack and repack the boot image then I can boot it with
Code:
fastboot boot unsigned_new.img
but I don't know how to add the BTFM.bin to the extracted folders, and then repack, in a way that the device may recognize them.

I see. If I only had a way to connect to the internet and log in with my google account I think the problem would be solved.
But I cannot find a way to do so.
I already tried to put BTFM.bin in every folder and repacking using AIK, it boots up, but the system won't recognize the module.
I also tried using an ethernet and a wifi OTG without success as it should be enable in Developer Options.
Thanks anyway!

well if you want to connect to internet from PC to your android by USB you just have to use this tool and enable the OEM Unlock option
https://github.com/Genymobile/gnirehtet
I had a similar problem downloading the version of my Revvlry+ = Moto G7 Plus XT1965-T and then OEM was disabled and internet and baseband modem stopped working because I downgraded too low and with this tool I managed to recover.
but everywhere in the web I am looking for the way to restore the status of my device because in Bootloader Mode it says: flashing_locked. instead of telling me: oem_locked
and you can't remove the warning that appears every time I turn it on

Hi, darkherman,
thank you for you reply.
Unfortunately it won't work as according to documentation: "Make sure you enabled adb debugging on your device(s)."
I have to boot the system to enable it in Developer Options.
Thanks anyway!
Is there a way to bypass the Google Wizard and boot the system without logging in?
About the warning on startup I've read somewhere that's not possible because of some var value obtained from:
Code:
fastboot getvar allCODE]
Don't remember exactly what var, but its value may be 0, 1 or 2 that means locked, unlocked and relocked (not necessarily in this order)
-- runnig the above command I saw some variables such as securestate, verity-state and iswarrantyvoid than may mean something.
But, as far as I know, we have no command such as "set-iswarrantyvoid false" or "set-verity-state 1" or something like that.
Maybe this could be done by replacing/updating the firmware if possible, but I think it doesn't worth the risk of making the device irreversibly bricked.
Thanks again for your reply.

It seem there's no way to rescue it.
Gonna just give up and throw it away.
Thanks for those who tried to help!

Hi,
I've just semi killed my XT1965-2.....
This would be my last resort:
Might have to open it up and short the test points to get qloader edl mode to be recogized because I believe a blank flash.zip method will bypass from your sd card will reflash your device with an unlocked bootloader so you have fastboot access to flash firmware... I could do this but its not the best advice if you never have took apart a phone or know about test point shorting to emergancy mode.... Or If it is an unlocked no carrier phone buy you another just like it somewhere with an easy return policy and buy extra coverage for damage....Break the screen or whatever so it wont power up the return it and demand your money back... You would be out the price of the extended warranty...

Hi, thank you for your reply!
I really never have took apart a phone nor know about test point shorting so this is not an option for me. I could even try to do it but probably won't be able to mount it back.
It's a no carrier phone, but in my country, there's no so easy return policy that I know of, unfortunately.
The bypass won't work because the second pass, "Connect your Motorola Moto G7 Plus to your Wi-Fi", as I think this is the biggest problem, I cannot connect to Wi-Fi. I also tried the method suggested by @darkherman throught gnirehtet with no success.
