[Q] Acer Z200 back to stock rom - Android Q&A, Help & Troubleshooting

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

[Q] IMEI is correct but no network detected MT65xx

First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.

THL W8S : IMEI invalid after few flash

Hello everybody,
I bought recently my thl W8S, and I was experiencing some troubles with the battery charging (taking 10 hours) and my GPS connection.
So I decided to flash it via CWM. But I'm very new in the flashing and all this stuff. I tried a lot of things to get CWM , even thing I didn't know.
The problem of my IMEI came out atfer I installed this :
http://forum.xda-developers.com/showpost.php?p=19319421&postcount=23
The recovery installer apk, I just click on it and when my phone rebooted, I didn't have any access to my SIM management, no more coverage of course.
I tried the *#06# and my 2 IMEI are just marked as "INVALID".
Since yesterday I tried few different operations to get if fixed but nothing is working.
I tried to use the engenering mode (menu CDS, Network information) and send the AT command with the IMEI but I got an error message : AT command is failed to send.
Then I tried to recreate the MP0B_001 file with some tools I downloaded. And I put it in the right folder (/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001) instead of the old file. I reboot my phone, still the same trouble.
I'm kind of desesperate right now.
Any thoughts / ideas?
I can't find the stock rom to try to flash it with Odin ..
Thank you
Hello
I tried to do this but I can't send any AT command , error message is : AT command is failed to send
Any other idea please?
Hi, Did you finally managed to fix the imei issue? I have the exact same problem.
I have the exact same problem. Who successfully solve this problem?
If you didn't back up your efs partition then the only other allowed way is to send it back to the oem.

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.

Imei Problem

Hello xda users,
Yesterday I flashed a custom rom (Darksense) on my elephone p9000. Everything went fine, that's what I thought.
My imei are changed to 111111111111111 and 222222222222222 , I cant receive sms and calls anymore.
Is there any way to change imei for the elephone p9000 ?
I was looking on engineer mode but...
There's no 'cds informations' on this phone.
Thanks in advance for any help.
reflash the stock rom and then follow the video https://youtu.be/w9POQK3kf6U
Reinstalled the Stock ROM but there's still no 'cds informations'
I'm really lost, cant receive any sms nor call :crying:
http://bbs.elephone.hk/thread-12457-1-1.html#.WBzMwPqLQdU
This method returns me that error: "Execution Warning : NVRAM database file is inconsistent with target load"
Still having the imei problem. My phone is a toy right now.
Can anyone give me some help ?
Been waiting for months now to see if the IMEI can be recovered. At this point it's a glorified PDA...
Moved on to bigger better things...
Managed to fix it !
Thanks to @jay98shankar
1) http://www.needrom.com/download/android-6-stock-20160401/ Sign up and download this (dont download the latest official rom(810) this is the only rom which can help you)
2) Flash using sp flash
3) Go to engineer mode you'll find CDS Information
4) Avoid formating your phone using sp tool just - formating made all this problem

Trid this before but hell, try again.
Same results - after entering AT+EGMR"IMEI" (imei number, not IMEI....) I hit Send AT Command and get " INFO - This command is not allowed in UserBuild"
Still no love.....
@ultramag69
Add a space between AT+ and EGMR.
The command must looks like that:
For IMEI 1: AT+ EGMR=1,7,”YOUR NEW IMEI"
For IMEI 2: AT+ EGMR=1,10,”YOUR NEW IMEI"

About ready to throw out the window....
Might just use as a codi remote... This is taking too much energy for a Peice Of Sh!t phone...
Download MauiMeta 3G, install the drivers for P9000. I think you can use the same drivers as SP flash tool. Run Mauimeta, choose something like "flash imei", laod file witch is named MDDB_**********.EDB. Shut down your phone, press on start and turn your phone on. Write your imei into the textfields and flash it. (For me it worked only with Stockrom)

[Q] IMEI Deleted

Phone bricked, used sp flash tool to unbrick via stock rom I found online, wasn't carefull, selected format all + download instead of download, IMEI went blank. Tried MTK engineering, CDS INFO is nowhere to be found,even tho it is installed in apps, chamelephone, wouldn't work, tried flashing zip made with IMEI Maker, wouldn't work, tried MAUI Meta Tool, wouldn't let me select download IMEI. Also for some reason couldn't install xposed, magisk gives me an error when merging. Really could use some help, Im not very experienced.What to do now?

Hello [emoji3]
If you are using mtk phone write IMEI using mtk droidtool or sn writer tool. For tutorials just search how to write IMEI using mtk droidtool or sn writer tool whatever you want to use.
Thanks.

Warning altering the imei is illegal in many countries and so is just having the tools to do so. Always be aware of the legal rules in your country.
