Hi, Everyone
I am new to flashing of MTK based phones and found that they are relatively tough to flash for an amateur to start on for a beginner. I had fortunately taken a incomplete backup of my phone which is why I was unable to solve majority of the simple problems that I am currently facing. I saw that, MTK Droid Tools can be used to restore the NVRAM from a backup to restore the previous IMEI, Bluetooth address, WIFI address, GPS address but the software was asking for a .bin or .tar file and unfortunately I didn't know about NVRAM until now and I don't have the .bin nor the .tar file but what I currently have now is data.ext4.tar from my stock rom which has a folder called "nvram", I was thinking of manually replacing the folder I have with the folder in the root but I need a better solution than that. How can I convert or pack that folder as a .tar or a .bin file?
Regards,
Ranajoy

My imei no got lost while restoring backup using cwm..... i looked around the forum and the ".nv_data" method will not do because my efs folder has a file named "essiv" only and nothing else.....
if someone would confirm what files are contained in thier efs folder and mail it to me also i'll be grateful......
I don't think the 'efs folder' of one device can be used with other devices as it contains the device's IMEI number.
Could you elaborate a bit as to what did you do that resulted in the loss of your IMEI number ? It would help others avoid it in future.
Well.... i restored the same backup file couple of times 'coz i was trying to flash a new theme...btw i am on stock indian 2.3.5......
the files in efs folder can be edited using hex editor (read somewhere in the s2 forum...i don't remeber which thread) so the imei no. in that file can be modified...
Hello All, this is my first post in Xda-forum, I love they way u all interact and help each other out here...well u see I hav a Allwinner A10 based tablet called Ice Xtreme which is very cheap in India do a google search on this tablet. well the company did not provide any software and I had corrupted mine while trying to use a custom recovery which was not from a allwinner a10 based tab. Anyways after alot of fuss I got it fixed but still they did not provide me with the livesuit image. I looked for ways to backing up my current working firmware from my tablet but found none. So after alot of searching I found this Script at a forum which can dump the recovery, the bootloader, boot partitions and system and data folder. But throughout my experience with this Livesuit firmware things I see that the drivers inside the vendor folder are also important as no two tablets have same chips (some thing will be different) so I modified the script and build it into a script that takes most of the directories (excluding mount,as it has only ur SD n extSD data) The dump thus created may help in modifying another image to suit ur needs.
I have only been able to backup directories and boot,recovery,bootloader partition thanks to the original script. I have no Idea how to send/restore these files to the device after flashing another rom to restore most of the things. Any help would be a boon. Thank u all for ur indirect help in bringing out the geek in me.
Try it!! & post feedbacks and suggestions...
This helps to backup the rom files with only adb. Just start the batch file & relax while ur ROM is being dumped.n it will also keep a copy on ur SDcard too.
Just use
#adb backup
for back up and
#adb restore
for restoring
# command...
But will it be possible to extract different files???!!
Hey, suppose I wanna flash a custom ROM which doesnt hav all of my boards drivers in it. So if I backup using adb can I thn restore driver files from the stock ROM backup to the new Custom ROM...

thx..

Hi,
I've been searching a lot and I couldn't find a way to install this particular ROM, in the format it's been given to me. I have installed custom ROMs in the past, but all of them in ZIP file format.
It's a chinese tablet, model number MZ7061H1C2W1-LFH, QuadCore 1.3Ghz, 1Gb RAM and running on Android 4.4.2.
The ROM folder contains the following files:
- database folder
- boot.img, cache.img, recovery.img, secro.img, system.img, userdata.img
- MBR, EBR1, EBR2
- lk.bin, logo.bin, preloader_mr706.bin
- MT6582_Android_scatter.txt
Now, I have found some posts about how to install a ROM with boot, recovery and system img files, but none of them say anything about the rest of the files and I know from the source that the preloader file is particularly important since it's based on the hardware specs of my tablet.
The tablet is already Rooted.
Is there any way to generate the ZIP file, or what would be the way to install it?
I appreciate any help you can provide. If you need any other information please let me know.
Thanks.
Hi,
Thanks for using XDA Assist.

Good luck!
I want to make a full copy of a MTK6580 smartwatch firmware before make changes on it, but MTK droid tools I used before with other MTK devices can´t detect this... please, I need a starting point on how to do it with this device...
Thanks
A starting point:
SP FlashTool, a scatter file of similar device and cat /proc/parti*
Then change the starting addresses and sizes to match yours.

THANKS. I am not sure if I can access to /proc/ folder, from the device or the PC, or if partitions will list all addresses, but I wil try. I have scatter (and firmware ) of the same device (other brand, but same hardware) but I don´t know if same hardware with different firmware could have different partition addresses., so I didn´t use it to save my actual firm.
Thanks again this is a good starting point. :good::good:
Worked, I´ve got the /proc/par* addresses. I will try to do the backup now. THANKS
