#21

Requirements

* Download the latest version of SN Writer @ https://forum.hovatek.com/thread-15450.html
* For Android phones, install VCOM drivers on the PC using https://forum.hovatek.com/thread-440.html
* The MD1_DB and AP_DB files for the phone model from the firmware (see https://forum.hovatek.com/thread-11609.html)

Procedure

See the video tutorial below or @ https://youtu.be/BYr7wcvxBvk





1. Unpack the SN Write tool zip file into a folder and run SN Writer as Administrator

5. The System Config dashboard should pop up

6. If you wish to write IMEI to the phone then tick IMEI under Write Option. Under IMEI Option, tick the appropriate option (mostly Dual IMEI) depending on the number of SIM card slots the phone has. For the rest like Bluetooth Address, Wi-Fi, Address etc, ticking the box in front of them is just enough

7. Click the MD1_DB button at the bottom. In the Window that pops up, navigate to the location of the MD1_DB file (usually named like BPLGUInfoCustomAppSrcP_MT65**.....), select it then click Open

8. Click the AP_DB button at the bottom. In the Window that pops up, navigate to the location of the AP_DB file (usually named like APDB_MT65**.....), select it then click Open

11a. If you're writing IMEI, enter IMEI 1 and 2 then click OK

11b. If you're writing Bluetooth Address and it is something like bc:b3:08:4c:1f:99 then you simply type bcb3084c1f99 then click OK

11c. If you're writing Wi-Fi Address and it is something like bc:b3:08:cb:c0:f6 then you simply type bcb308cbc0f6 then click OK

12. SN Writer should now display Start searching preloader com port and handshake. At this point, switch off the phone (still with battery inside) and connect it to the PC (do not hold any button on the phone) via a USB cord

[Image: how-to-use-SN-writer-12.jpg]

13. You should now see Start searching kernel com port and handshake, just sit back and don't interrupt the process

[Image: how-to-use-SN-writer-13.jpg]

14. You'll then see Start switch to MD meta and init Modem database. At this point, the phone will come on. Don't worry, SN Writer is simply booting it into Meta Mode

[Image: how-to-use-SN-writer-14.jpg]

15. Next, you'll see Start loop write data to nvram

[Image: how-to-use-SN-writer-15.jpg]

16. You should then see Start backup nvram to BinRegion, you're almost done

Hi,
I'm trying ti use SN Writer to re_write my lost IMEIs on AcerLiquid E2.
I've got an error message : EnterAPModemMetaMode() : Metaresult= default_FAIL"
(see att)
An idea to solve this problem ?
Thank you.

Edit : I'm Sorry, it works fine now... And I retrieved my IMEIs ! I tried a lot of ties, and don't see what was wrong at what time...
Really sorry !

Where do you get ap db file from? From your tutorial you're explaining on how to get the first file only.

Yeah, I need that file (APDB) too, it would be really useful to find out how to get it.

You get these files from the firmware.

The APDB file included with the firmware image I have doesn't work with SN Write Tool. I wonder if there's an alternative way to obtain it.

You need two files here, not 1.
Its Maui Meta that needs 1

I know that I need two files and I have both files, but in my case the file that does not work is APDB. I successfully restored IMEIs of the phone using Maui Meta and just the BPLGU file, now I'm trying to restore the serial number with SN Write Tool but the following error occurs:

EnterAPMetaMode() _ MetaResult =
SPMETA_DLL::META_MAUI_DB_INCONSISTENT
