[NEED HELP]G920W8 Knok Question About IMEI - Galaxy S6 Q&A, Help & Troubleshooting

Well my IMEI is borked after flashing a backup of what i thought when my phone was stable. Anyway i don't have the money to buy a octopus box or Z3x box so i was wondering if i go to my carrier could they reset it if i HAVE tripped Knox Also my carrier is telus and would they charge me?

Someone correct me if i am wrong, but if you don't have proper EFS backup (imei), and you messed up efs partition, there is no way you can get your IMEI back. And carrier would never do that for you (specially after you voided your warranty). And yes, changing IMEI is pretty much illegal.
Do some research on xda, i remember there was a thread on Galaxy S6 Q&A forum, one guy had same problem and he managed to fix it somehow.

IMEI is posted on the back glass of thr phone. Use a bright light to shine on it and write it down. At least if you have to have it reflashed you'll know what the device IMEI is and can restore with the digits.

[Q] Is there any way to get back my IMEI?

Hey guys! I'm sorry if this is an annoying question. I have a Samsung Galaxy SL i9003.
Not to make it too long i'll summarize my problem.
I had lost my imei once and i was able to get it back with 9 steps to get your imei back thread but now it doesn't work. When i dial *#06# it's BLANK. No Numbers or 0049 just IMEI and okay button. I have a backup but copying it back to Efs didn't work. I dont have an "insane chip" It's normal as brickbug checker app says. I went to a phone shop they couldn't fix my problem with z3x and stuff like that. Samsung service center wanted 175$ for motherboard replacement so i refused that it's too much for a 2 year old device. So yeah, is there any way for me to take it back to normal? 'Cuz i can't afford a new phone and they're all very expensive in Turkey 'cuz of dumb taxes Turkey has.
Hope to find a solution. Peace out!
ps. If this is an emmc problem is there any way to do some repartition to it?
Ps. Today i've flashed DDLF2 and i saw that it rebooted to recovery and there was an error which says "Cannot mount /efs" I hope you guys can give me some tips to solve this..

[Q] Nexus 5 Possible EFS issue, IMEI already repaired

First post, long time lurker, so i'll start with a big thanks to the entire community for all the help you've unknowingly given me.
I just got a nexus 5 to replace my original n5 which has a broken screen. I took a backup of the original and restored it to the new one. Unfortunately i didn't know what EFS was, so i restored the old EFS to the new phone. IMEI went to zero. HUGE BUMMER.
I was able to fix the IMEI with QPST, but the new phone will not connect to the network. I've run a check on the IMEI and it is not blacklisted. Without incriminating myself, lets just say that i'm positive that the new IMEI is good.
The phone recognizes that i've inserted a SIM but shows no signal. I've tried to search for networks, i've checked the APN settings...
I REALLY don't want to send this to LG since they can't give me a price or even a ballpark figure without me shipping them the phone...
Any advice on next steps would be greatly appreciated.
What should i try next?!
flash the factory img and do not restore your efs on it.

I guess i should have mentioned that i've flashed factory also. Currently the phone is on the latest firmware, unrooted, locked bootloader. Flashing factory had no effect at any point.
I bought this phone on Swappa BTW, so i am assuming there are no hardware issues. I'm not at all certain what else may have been screwed up by having another phone's EFS restored over this "new" phone's EFS...
More Info
I am able to attempt to manually select the network. When i search for networks, the available networks are shown, but when i try to connect it shows the Registering dialog for quite a while, then fails. This is the same behavior as a working phone without a SIM installed. The odd part is that the phone will recognize when a SIM is installed or removed. It seems that my problem may be that the SIM is not being read properly or the data is being lost/corrupted between SIM and antenna. Is this possible? Is this EFS corruption? is this something i can fix? Please help.
Bump?

[DEV] N5 efs repair

So for now it will be 2 weeks of this anoying issue that phone radio just disapers, in setting section it just say "radio off", first I thought I am lucky and factory reset helped but as time passed it hapened again againa again..... For now it seems completely shutt off, because nothing bring it up online. I had made diferrent tehnices like bringing phone in diag mode that for some time helped and setting some of nv items to defaults(found default walues in internet), changing radio mode in DFS but as I sad now nothing helps. So I ask someone of you guys for helping hand to share efs partitions efs1 and efs2, to modify them whit mine setting(esn, imei......) to try this last chance. Or I will need to buy other phone as mine dosn't had warranty. And if I succeed I will make universall efs dump without esn, imei, meid... so they can be filled with your stuff.
So I am asking for someone who had twrp backup of efs or can dump booth partitions of unmodifed band N5 D821 international variant. And I can promise I will not use your imei esn and other settings as I can read mine so they aren't damaged. And please if you share it do it with pm as thoose partitions contain your phone radio info and provide radio version who you are using.
P.S if someone had simallar isues and had repaired it please share it
[EDIT]
Please share efs partition I will pay you if it help me because new mb is 190USD and I realy like my phone.

MI4C IMEI/Baseband unknown

Hi guys!
Yesterday my firmware update went terribly wrong and now I have a device that states that imei and baseband are unknown, so I my both sim-cards don't work.
I've tried several types of IMEI restoration, but none of them worked.
Unfortunately I don't have any backup for nvram. So, my guess is that there is a problem with EFS partition on the phone.
In QPST NV RF Manager I see my real IMEI from the box, so I guess it is still present, but my baseband doesn't work. Can you please suggest any help on recovering the baseband? Or if it is possible share with me modem backup or nvram backup without IMEI (I've seen on this forum that one guy with Samsung S3 had a kind of the same problem and he was given a working nvram backup without IMEI (IMEI was 0/00)) I can write my IMEI then, if baseband works again. Will appreciate any help.
Send it back. Only the oem is legally able to mess with the IMEI.

Well... I have managed to make it work again and my original IMEI is back. The only thing I had to do is to restore a working NVRAM backup (from another device) via QPST. So, it wasn't that hard. Much simpler than sending it back to China.

If you restored the file from another device then it won't have the right IMEI.

It HAS right IMEI, I checked it with the original box. No need to put up an argument about it. Both devices (mine and the one which was backupped and restored from) are working fine, bot have ORIGINAL IMEI numbers and no errors considering networks or MI accounts. So, actually I have no idea what you are trying to tell me.

I'm not making an argument. I'm trying to figure out how a number which is supposed to be hard coded into the file is then restored by restoring the files from a different device.
As these devices are not sold in the states learning as much as possible is a good thing.
Glad you got it working.

Okay, sorry. I will try to make it a bit clearer=) This device is not sold in Russia either (officially at least), so the only way to get it is to buy from aliexpress or ebay or anything else. In that case the buyer doesn't get any guarantee or official support. So if the device is broken and can't be restored it turns into a garbage. I believe that in the US the situation with that kind of devices is almost the same.
Now, if You are not familiar with QPST it is a software package for qualcomm based devices which can make backup/restore of some non-firmware software from the device (like IMEI, ESN, Baseband, LTE Channels etc). As for IMEI number, basically, as You've said it is hard coded into device so it is pretty hard to get it changed or fully deleted. Here we come to my case of unknown Baseband and IMEI. Though via phone settings I could see: "Unknown", my IMEI didn't change and was stored in the device. The "error" or smth like that happened after the factory reset and my guess is that the file structure of NVRAM was changed. So, backup of NVRAM taken from the working device didn't actually have IMEI or ESN in it, but it has the right file structure without any errors. That is what happened, the file structure was restored without changing any factory numbers.
If you have any questions, feel free to ask

It is almost the same with a few exceptions. One being that their devices are banned from all people that work for the government, sometimes they get stopped at customs due to copyright issues and with the latest news about them coming loaded with malware, most won't buy them.
That makes sense in a way. Not sure why a factory reset would mess up that part of the device as it shouldn't touch it.
Thanks for the info.

I don't know either, but it was an unforgettable experience and a lesson to do backups of everything.

Hi! Have you tried flashing China developer rom with Miflash?
Second option: Connect to your PC and run QPST according to one of the manuals (in order for your phone to show up as a COM), run RF NV Manager and look up your line 550 NV_IMEI if it is filled with numbers that are the same as on your box (check HEX above them and numbers should resemble yours from box but written in opposite direction, eg: on the box it is XXXX69XXXXX in the QPST it will be 96). So, if your IMEI is at its place than all you need is a working device from someone to make a backup. Backup must be made in newer versions of QPST in *.xqcn format and than restored to your phone with checked box "allow ESN mismatch"

I looked that thread up, that apparently is a fix for devices stuck in EDL mode, My device is booted & functioning properly other than no IMEI display in dialer *#06# and Sim/Network not working
Does your fingerprint reader work? That would be surprising, like hundreds of users on Zentalk who have an HS SIM, it is the disconnected cable that is in question and that manages both (SIM and Reader footprint).
