Here it says as a solution for a type of a phone. There are other question ( upvoted) but closed by somebody marked as to localized. Of course it is localisez for each type... why don't want to allow to get help?

I am searching like a week how to solve my THL W8S problem. I could go on others answers too, but those questions it seems they aren't active anymore.

Tried with MTK tools, and other tools, since this phone has a MK5689T version on it. Used the hidden engineering mode too with dialing a "secret" number. On that case I could set the old IMEI back, but that will be lost after factory reset.

Please correct me if I am wrong:


This holds the IMEIs ( I have dual sim )

/data is wiped after Factory Reset => IMEI lost after factory reset.

Question is what to do to make it persistent?

At /etc/firmware/modem.img I have the .img, but don't know how to read it, where to mount it,even on Linux after saving to desktop. Has that img inside of him a MP0B_001 file? Would it work if I mount , unpack change the file and repack?

I have downloaded the official rom: http://www.thlmobilestore.com/news/

Title: ThL W8S

ROM Version: ROM Android 4.2.1

Link: Here

The ThL_W8s.JB2.FHD.EN.COM.16P256_MT6589TV1.0.3_20130815 content is:

enter image description here

If I unpack I see a boot.img That file need to unpacked to get the modem.img?

Where it stored the phone serial number? - I need to restore that too ( to original one) I have found only which environment properties has it, not where it is stored. It is formatted the NVram accidentally by pressing the Format on a SP Flash Tool.

At baseband version I see: Moly.wr8.w1248.md.wg.mp.v7 and I see a file BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V7 there it should be written the SN + IMEI?

Thanks for any try to help.
