[Micromax Canvas Nitro A310/A311] hem.crz:
Take Readback backup of Entire Rom/Recovery on Micromax Nitro 2 E311

Steps:

1. Download Mtk droid Tools, SP Flash Tools, drivers for your phone, (no need, just connect your e311 to pc and choose connect as built in cd rom and install drivers).

2. People having windows 8/8.1/7 first of all disable driver signature verification(google it, pretty easy)

e.g. on windows 8/8.1 go to bottom right corner,choose setting on charm bar,select change pc settings, update and recovery,go to recovery,advance start up,restart, advance startup/troubleshooting, disable driver signature verification by pressing 7 on keyboard(you need physical keyboard, touch keyboard won't be there).

3. READBACK ROM BACKUP

i. open/run as administrator MTK droid Tools, your phone should be switched on, connect it,accept usb connection on phone, let the droid tools detect it and show its specifications.(make sure usb debugging is enabled)

ii. click on blocks map, a window tile of block info will pop up. Note down or better save it using notepad++/screenshot by pc or ms word file, you need values of preloader and userdata/(some other phones may show FAT,don't panic,it's just your internal sd partition) under scatter column(also note the values under size column for backing up a single item like recovery, for entire rom you only need scatter column values of preloader and userdata/FAT).

iii. alongwith block info, a tile asking to creat scatter file will pop up, create it. This will be our scatter file for SP Flash Tools.

iv. Disconnect usb, switch off phone. you may close mtk droid tools, it will be needed after next step.

4. Open/Run SP Flash Tools as administrator,

i. click scatter loading and select previously created scatter file.

ii. click on readback tab on sp flash tools..then click on add button.

iii. double click on the item (it should be checked in the selection box)and save it as ROM_0(default) or ROM_1 , it does not matter.This will be a large file approx 3.2 GB so save it to a dedicated folder on pc not usb.

iv. next readback block address tab will open, under start address value will be like 0x00000000, leave it as it is(don't change to 0x0), under length use the value under scatter column of userdata/FAT previously noted in block info..Make note that value entered should be like 0x1234567 and not like 0x0001234567. the zeros after 0x should be removed and only till first non zero value after that and middle zeros like 120458000 shoud be written as it is. The length value may be numeric for some phones but e311 will show like 0x000CDF7000, Don't worry enter it like 0xCDF7000. This is just example not actual value, i assume each phone will show different value.

v. after entering length and pressing ok, click readback and now connect switched off phone.

vi. after that click ok and wait for readback to complete. It will take about 7-11 minutes depending on your pc processor. a green check will appear on completion.

vii. close Sp flash tools, disconnect usb. switch on phone.

5. Open MTK droid tools,connect switched on phone,select the root,backup,recovery tab.
