Thank you
Very well written, amazing work, thank you for mentioning me too.. For all who lost their imei's, feel free to ask anything about that matter, we have more methods to recover it.

@rombdeta
I think you should post a link to the original thread on htcmania

Thanks
Thanks everybody helped for this tutorial.You are just great
I have done what inside the tutorial,my problem is i have only 3g,so it goes to :
-Have imei but radio off and you can't change 3G to 2G or LTE, it's always in 3G. Put the QCN again, and only click in WRITE NV.
Where to put the qcn again? I presume rf nv manager ,right?
Thanks again ,you are life saver

Yes right, but first do a full backup with QPST, then, yes put my QCN in RF NV Manager, wait you will see "the program can't resset your phone" or something like that, power off your device, and power on. You will see your connections.

I think the qcn is not original ,its edited .Because once i check the imei, it belongs to Samsung Mobile.Maybe thats the problem.
I go trough the guide.I have the imei (Samsung Mobile) and 3g but not 2g.Then i write my original imei,i have imei,3g and baseband but no 2g..Then i have full backup of my qcn by qpts.I open Rf NV Manager and put your qcn,then what?Because nothing happens.Pls help.

RF NV Manager
@rombdeta
Could you pls explain to me the steps after put the qcn to RF NV Manager?
When i press put the qcn into rf nv manager , there is no nv items.I chose read supported rf nv items and go to 550 enter my imei,click write nv,write only listed nv items to qcn ,its okay.But once to restore the qcn with qpts there is no imei ,baseband,no signal,nothing.
I appreciated your help.

No need to save the QCN, because that remove some of the QCN package, so you only have to click on "Write NV". Rewrite the QCN package, and do as I tell you, if you can't repair your device, send me a message and I'll help via TeamViewer. Greetings.

Hi @rombdeta, I followed the procedure to restore my IMEI code, but when I click on "settings > comport" the "RF_NV_Manager.exe" crash.. What can I do? Where's the problem?

Try with other PC

I really need help. Gone to CM11 version as specified done the adb shell. Now trying to config a COM Port. I don't know which COM Port is mine? I've got the A001 showing once in other devices with a ? and i have an android device stated as ADB shell in another.
I'm really confused. Please help

Thank god
Figured it out. Might i suggest a re-write?
Very much appreciated though!!

rombdeta said:
IF YOU HAVE A 32 bits operating system, you will see two A0001 in devices manager
click in the first, and install like the images 1 to 10.And when you open QPST, use the port who is in my case COM3.

@rombdeta sorry if I annoy you, but I want to ask why I do not have "images 1 to 10", and how I know what COM port is my device? (In "ports (COM and LPT)" in device manager I've only "communication port (COM1)" and "printer port (LPT1)")

Now I have my IMEI and my SIM just works fine. But I have a problem, to connect to a mobile networks the phone takes more than one minute, and I have to search the networks by myself.
EDIT: I noticed that 3G works (connected in 40/50 seconds, I think it's a bit slow) but the phone can't connect to 2G, with LTE didn't tried becouse at home I don't have it.

Received an invalid command from the phone.
what can i do after i press start it gives me this error " Received an invalid command from the phone.

[TUTORIAL] How to restore Wifi/BT MAC the proper way

There are some chinese distributors that accidentally clears your NVRAM when flashing their ROM, thus the phone loses IMEI, MAC and other serials.
There are some methods that fixes this by copying files to data/nvram etc, but that's just a temporary fix, and resets after a wipe.
Here is a proper solution. Windows 10 tested.
Do NOT connect your phone yet. Have it turned off completely.
First you need to install the drivers.
Run
Code:
All MTK USB Driverv.9.2.PDanet.Adb 2015\SmartPhoneDriver\Driver_Auto_Installer_SP_MTK\Driver_Auto_Installer\SmartPhoneDriver\x64 or x86\spinstall.exe [B]WITH Administrator privileges[/B]
Maybe there are some other drivers needed, I don't remember all that I've installed. You will find a lot of drivers in my Google Drive (link at the bottom).
Install SP META, and run it. You need to select AP NVRAM Editor and press Connect.
Now connect the phone, it should detect it, and pop up a window.

}
Press Read From NVRAM. Browse APDB_MT6795_S01_L0.MP6_W15.32 and press OK on the warning.
WIFI MAC:
SELECT RDEB LID/AP_CFG_RDEB_FILE_WIFI_LID/1 and press Read From NVRAM
aucMacAddress will be your WIFI MAC address. You need to write every 2 character like 0xD0, 0xB3, etc.

Yes, it should work. You might need a different APDB file, but that should be in the ROM package for your phone.

thank you for your reply but in the rom package of letv x600, I couldnt find any APDB file. Could you take a look at the rom package in the attachment for me. Thank you!

First try it with my APDB, only if it not works find another.
And it should be in ROM packages that can be flashed with sp flash or fastboot.

here is the rom package that can be flashed with sp flash tool. Would you mind taking a look at it again. I wonder if using your file might brick my phone or not. Thanks!

I can't see it, you may have to get it from somewhere else then.
It can't brick your phone. This only touches your NVRAM, so make a backup of it, and you are good to go.

i tried this, i lost my imei and all the time i do a factory for install new rom i've to place the mpb file inside nvram folder, but don't work. I can modify the array in IMEI[0] and IMEI[1], i can write it to nvram (and it remains inside) but if i reboot the phone, i have no IMEI :/
EDIT: i tried to flash an nvram backup of a friend with the same smartphone too, i have initially his imei that i can canghe with the mpb metod, but if i try this guide with his backup flashed his imei is not saved into the array IMEI[0] or IMEI[1]...

If the written values remains inside nvram, then it's most probably some modem inconsistency. First of all, don't change the nvram folder on data, it can overrule the changes you made in the real nvram.
And try to flash a stable rom with MI Flash after you have changed the values in your nvram.
Note: I hope you wrote the 2 digits backwards, as I said so.

Do a factory reset, that resets the nvram folder. Or you can just delete the nvram folder from your data.

Hi,
I have the same problem with the IMEI.
I tried to use the fastboot, but couldn't find a proper guide how to do it (can't connect the PC to the phone when it is in fastboot mode). can you help me here? is there a step-by-step guide for newbies? can I use the phone ROM update utility instead of the MiFlash? (what is the difference between the two?)?
in addition, I did not fully understand the steps you've done to recover the IMEI. when you write "First i delete the folder nvram, then factory reset from twrp", how did you deleted the folder (using a file explorer like ES file explorer?), what is twrp?
Thanks in advance.
OKup.

It should be use TWRP to Root your RN2 then delete NVRAM folder using ES File Explorer.

Universal ReadBack Extractor for mtk feature watchphones

Update Mar-12/2016: as long as on the market appeared a long line of new types of mtk6260 mtk6261 mtk2502C mtk2502A (etc) watches equipped with strange new PCB or flash_ID parameters, the new release <Readback Extractor mtk 2.0> now has the capacity to identify, to read, check, rebuild firmware and collect and insert in the .cfg files the flash_ID's coded inside the ROM dump for almost all types of mtk watchphones or smartwatches based on RTOS Nucleus
NOTE: being tested already for mtk6260 mtk6261 mtk2502C and mtk2502A
In short - if you intend to install in your smartwatch new firmwares, mods etc, before to initiate any flashing with the Flash Tool app (pushing that goddamn < Download > button) think twice, 'bove all better DO a backup for the original firmware, why so? because it's containing all original drivers hence you'll be able to recover 100% your watch in case of bricking.
How to:
First you have need of a full dump of your ROM. Assuming that you already got a Flash Tool 5.15.16 and drivers, and you were at the point of flashing something (already chose the download agent and scatter file)
preparations:
a. Set options/backup and restore on no action
b. load the download agent (you find this file inside the flash tool folder)
c. load a scatter firmware - for initialization flash tool needs a scatter file (.cfg) - for dz09 you get this one - for any other than mtk6260A get here and get a firmware compatible with your PCB
d. in case you have W10 - go to the start menu and click on power and hold down the shift key while clicking on restart. A screen then comes up and you need to choose troubleshooting and then startup options. It will then reboot and give you a menu. press 7 which is ignore signed drivers and then when windows comes up, you will be able to install the drivers.
for instance let's say you have a DZ09 smartwatch:
1 - press < Readback > in upper menu and so < Add > in the middle menu
2 - click twice on the item appears in the main window, set name as ROM_DZ choose in browser the path and save
3 - set as Physical start address 0x00000000 and as Length 0x01000000 or 0x00800000 or 00400000 (try them in this order) then ok
4 - turn off the watch, press < Readback > in the middle menu wait 2 seconds and connect through USB your watch
5 - wait until the upload is complete (big green ring)
Now second stage:
1 - download the app I've built attached here (Readback Extractor mtk) and unzip it
2 - create a folder where you intend to keep in safe the original firmware and name it for instance DZ09-Orig
3 - do a copy of Readback Extractor mtk 2.0.exe and place it inside the DZ09-Orig folder then click twice on it
4 - press <Load Readback file> and browse after the ROM_DZ file created before with the Flash Tool then open
5 - Wait about a minute while the app will check bit by bit the integrity of your file
6 - If everything went ok and your file is healthy then app will show " health 100% " so you can proceed to the next step
7 - Press <Rebuild Firmware> and wait about one minute (it shows a progress counter)
8 - When appears the message " - ALL DONE!!!" close app and go back in the DZ09-Orig folder, now you'll find there a set of new files which are the original firmware kit ready to be flashed back in your phone anytime you want
9 - Enjoy flashing anything you like without any fear that something bad can happen
Some tricks for writing IMEI in your watch NVRAM:
you connect to usb your watch (turned on this time) and set the com port on the watch screen, go in device manager and check the port number your watch is connected, then you open Tera Term hyperterminal (google for this app), connect it as serial com on watch com port and then give the command:
AT + EGMR = 1, 7, " imei number "
if on screen appears OK then ready, you've changed your imei
AFTERWARDS READ ME story - Anywhere you search, there is no one to tell you explicitly how to extract from your mtk smartwatch the firmware kit
All says a halfmouth: Do a full < Readback > in Flash Tool, you'll do it being confident that from now on you say goodbye to any risk because you have A BACKUP hence you start flashing new firmwares. And the Big Brick is coming , you smile and get back to your < Readback > backup discovering that, sadly, you have a binary bulk at first sight good for nothing. It cannot be so useless, isn't it? after all it contains full dump of your ROM! I was in exactly the same situation, so 'cause I didn't find any answer I've started reverse engineering . . . and it worked, first I did it manually for guys being in the same situation, 've noticed that is a common issue so I had to choose how to help, simpler but dangerous (for you) way, to create a tutorial <how to> or the hard way (hard for me), to develop an app which will do all "cooking" automatically and I choose the second because in manually way there is a quite big "chance" to mess up with your primary bootloader which could get to a real tragedy - no modem - brickest brick you saw in your entire life

Look at the bright side, best lessons we learn from our own mistakes, best part is that if you buy the new one from the same seller, you'll have the firmware hence two working watches!

Are there apps in the works to change watch faces without flashing?

Unfortunately, yet, there is no way to get in contact with the watch else than through proprietary mediatek drivers so that the only ways to communicate for now are Flash Tool app and bluetooth modem proprietary commands (the most important of them being secret as well)
To do such a reverse engineering is way way way over my pay grade
Still I'm working for an app which could replace any media in the watch (backgrounds, icons) but through flashing method of course

Thanks for the info...I just think this watch have great potential

I'm almost sure you found these before me, still, here link you have more than 10 versions of dz09 firmwares (others than we checked before)
It looks like they made a firmware for each phone ) very prolific guys when about dz09
Hope this time you catch the right one!

i struggled 3 days for this to find correct way recover my ime
tools here

From what I understand I guess you lost your phone.
You should have your EFS partition backup as it probably contains all the IMEI information from your phone. I can't imagine an EFS partition from other phone working into yours without duplicating an existing IMEI.

Did you backup the EFS partition before starting changing ROMs over and over?
If yes, try restoring it.
If not, nothing to do.

I don´t have the option
I have a Lecco Le x626 but when I write the code #*#76937#*# only appear one option "Sleep Sing On" no more what do I do for activate to option necessary for that thanks

maybe a stupid question, but if I do a full backup including nandroid via TWRP before flashing anything, will the imeis be included? thanks

Only if you check EFS partition to be made a backup, otherwise IMEI will not backup.

Sadly, the x626 (a.k.a Le S3) is a MediaTek Device, so no Qualcom Mode available.

Help, QCN file needed

I have recently bought an Essential Phone from ebay with broken radios. No imei, no wifi... After troubleshooting, I found out that the QCN file was completely wiped. I have the original imei written on the phone and paper but need the copy of QCN to restore it. Could somebody please help ?

It's not safe to share imeis. Could you just edit yours with dummy imei and pass me the file? I can hex edit my original imei into it myself.

You are right. Actually, I dont have much to lose anyways as the phone is becoming replacement parts if I can't repair it. I will sent the imei via pm. Also, not sure if qcn restore if even enough, there is a chance of broken efs as well.

Qnc fixes efs....if it doesn't you could send me your nvrf partition,I could inject your IMEI into the one I pulled from mind and send you the fixed one...

Hi
Hello everyone I am so sad. Because A few days ago I noticed that the baseband was unknown. IMEI 1 and 2 unknown and Android ID Null from my Asus rog phone 2 Zs660kl version I001DC Global version and I cannot do anything because there is no any Qcn file for this phone , I am unable to do anything in my own, I do not live in United states, I cannot send it to repair, it would cost me the tax again, like 147 dollars again that I paid for the customs. Please if anyone has a good hearth to back up the Asus rog phone 2 file from the same version with the qpst toll... I would really appreciate. I need it , I tried to find the IMEI with Hxd editor and there is not any 1111 to find the error so I am unable to to that. There is no any Qcn file. I need a Qcn file from the same phone with a phone that has the baseband and the rest fine".
I need to have the Qcn file from this same phone I have issues with the baseband IMEI unknown and Android id Null, by doing this you can help through diag mode you just follow this just download Adb minimal, open it and and write Adb devices, then Adb shell then Su and finally setprop sys.usb.config rndis,diag,Adb enter and in device manager you will see in ports, Qualcomm devices which you can continue doing the next step which is installing latest drivers from Qualcomm on this video you can follow the steps After installing the latest qualcomm driver, the qpst tool will recognize your phone because it is now on diag mode since you did the previous step, by checking this video you can back up the Qcn file which is what many people need and there is no other way to solve the issue only with a phone which is in perfect condition as yours
how to use the qpst tool to backup the Qcn file , First diag mode with the commands I gave you second is installing the latest qualcomm drivers then backup and restore Qcn , and then you will have it done,
download the qpst tool and the Qualcomm drivers and it is an example of my problem with the baseband, you can guide with the one video and the third , the one video do not use the commands given by the YouTuber, because that do not works, use the commands I gave you , that works for our phones, and then the third video is explaining how to backup the Qcn file which contains the data? I was unable to edit myself the Qcn data from my damaged phone cause the IMEI is not there, there is no any 11111 number to replace it for my own IMEI, sadly,... Just need the Qcn from a good phone, please!!l

If anybody is still offering to do this and can help me... My phone is hard bricked and I can't do anything... I feel I can fix it with a QCN... Anyone want to help?
