I WHOLE formatted my Cherry Mobile Fuze Q390 (MT6582) with SP Flash Tool. Then I flashed the official firmware of this device with SP Flash Tool. I don't have any backups because I am reverting to stock. Now the phone works fine but it does NOT detect the SIM card. Also, the IMEI is shown as "INVALID" for both SIM slots when I input *#06#. When I try to fix IMEI from MTK Droid Tools it shows (ERROR : pttycmd1 device NOT found!). Also, MTK Droid Tools shows (Baseband V -----). I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. So the device has no baseband or radio files right not and also the data/nvram/md folder has nothing in it. Although, WiFI still works perfectly except the annoying NVRAM Warning that I kept on seeing when ever that I wanted to connect to a network. Now the official firmware of Cherry Mobile Fuze Q390 does not contain any nvram.bin file. It does contain the BPLGU file but I can't seem to modify IMEI with SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. I tried using the MTK Engineering mode mode also and tried to write it using the AT+ code but it keeps on saying failed to send command. Probably the SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. only modify the IMEI when the baseband or radio files are already present on the phone. So I think the only way out for me is to flash a nvram.bin using SP Flash Tool or Flash nvram.bin+nvram.tar to MTK Droid Tools which I don't have. Any ideas whether I am on the track or not? If I am, then how can I get the IMEI back on my phone. As you people can see that I have tried a lot of things, so please suggest/advice accordingly and any help would be greatly appreciated.

Invalid Imei Lenovo a820 again..

Hello,
I have lenovo a820, and long time have problem with "Invalid Imei". I have second phone, where all work good. I try make full backup by MTK droid tools ( on good phone), and download by Sp Flash tool to phone without imei. But don't know why, it still don't work. I try one method more, by using MTK Nvram Tool, ( backup on good phone -> restore on phone without imei) still without any changes . And one method: by using "MTK Mobileuncle Tool" but on this when i try send command i have problem "Can't send~~(I don't remember)"
I don't have any idea what i can do now, maybe something is wrong with hardware in phone?
Thanks ALL for any help.
Sorry for my bad english..

I try do it by Mtk~ but when i write, enter and reset phone then still is invalid imei

[Q] Acer Z200 back to stock rom

Basicly loaded a dual sim rom on a single sim Acer Liquid Z200.
was helped so far in this thread: http://forum.xda-developers.com/and...ms-cwm-root-acer-liquid-t2960787/post59482099 by @Shreps, but somehow i got this message that due to the 10 post rule i wasnt able to post anymore.
Downloaded the last zip file, but CMW doesnt seem to recognize my SD card.
Tried to load the rom with adb using sideload, but get the message cant find device.
Is it possible to load another version of CMW, mount it with USB and flash the zip file from the pc? And can i use any CMW file or are the custom made for each type of phone/brand?
Any other suggestions, got no clue what to do now
edit 18-3-15:
Tried to re-load CWM with Smart Phone Flash Tool and got this PMT changed for the ROM; it must be downloaded
Update:
Did a format of the device using Flash Tool, MTK USB poort was loaded and was able to flash the ROM for dual SIM.
@stef951
Try to flash this firmware from a Recovery :
update-Acer_AV0K0_Z200_1.012.00_EMEA_GEN1S-sds.zip
It's the stock firmware Single SIM EMEA GEN1s, you should back to your original firmware.

used recovery to install the firmware for sinlge SIM.
However now stuck with IMEI issues.
Used Mobile Uncle Tool and MTK Engineering to get into Engineering mode, but get this message: "cannot find engineer mode app"
*#*#3646633#*#* doesnt do anything. Possible that Engineer mode isnt installed? And is it possible to install it on my device?
Tried to load IMEI with MTK droid gave me a message "Changes will come into force after reset", but nothing changed -_-
Any other options on this IMEI matter.....?
Finally found a solution to enter Engineering mode, type *#*#2237332846633#*#*
When i try to change the IMEI with AT commad get a message AT command is failed to send
Tried Uncle tools, but unaible to acces engineering mode with this app.
I can enter a valid IMEI in MTK tools, but after reboot its still unknown.
Tried to copy a new MP0B_001 file to the NVD_IMEI folder
but all failed :crying:
Still searching for the solution, but if someone over here can help me out it would be appreciated.
Phone is not reading SIM card neither, is this because of the IMEI issue?
Acer Z200 Working again!!!
GOT MY PHONE BACK TO LIFE!!!
Lost the serial number and IMEI, had to write them back to NVRAM using Maui META tool.
Tutorial how to found on http://www.gizbeat.com/6058/how-to-...-for-mtk6582-mtk6572-mtk6592-mtk6589-mtk6595/
In the attached ZIP the files i used for the Maui META tool
Android_Gadget_CDC_driver, CDC driver didnt got installed so had to do this manually.
MTK6572 database: BPLGUInfoCustomAppSrcP_MT6572_S00_MOLY_WR8_W1315_MD_WG_MP_V1_P3_1_wg_n
If you have the serial and IMEI number, go to method B under Restoring Values and add the manaully.
When loading the MTK6572 database i also got a warning: execution warning nvram database file is inconsistent with target load
Ignored the warning and just writed the serial and IMEI to the device.
Disconnected, rebooted and got a working serial and IMEI.
So happy that the damn thing got working again.
bro I saw your successful post about Acer Z200. but I can't install CDC Serial Driver .
. how to Install Manually ? Android_Gadget_CDC_driver, CDC driver.
Can you explain to me.
Thanks in advanced
