hey!
while flashing roms, many times we get a "status 7 error". while searching in many threads, we do not get how to resolve it. i will tell you each and every thing step by step
so i made a
NOOB FRIENDLY WAY TO RESOLVE STATUS 7 ERROR
make sure that the rom you have downloaded matches your phone model, if you flashed some other rom, you may hard brick your device.
1. First extract your rom (for example using 7-zip)
2. Go to the folder META_INF > COM > GOOGLE > ANDROID
3. Here you will find a file "updater-script"
4. Rename this file as updater-script.doc (microsoft word format) or use notepad++ (preferably)
(in some pc, extensions are nor visible. to make them visible, follow these steps)
Open Folder Options by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, and then clicking
Folder Options.
Click the View tab, and then, under Advanced settings, do one of the following:
To display file extensions, clear the Hide extensions for known file types check box, and then click OK.
5. Double click to open it( microsoft word preferred)
6. delete text, starting from "assert ....... till the semicolon(

of the last getprop command. (see image in attached file-lines to delete)
7. Now save the file
8. Again rename the file, and delete the .doc extention
9. now go back to the main rom folder where you extracted the 3 files. zip these files again. and you will get a zipped rom.
and the status 7 error has now been removed!:good:
happy flashing :victory::victory:
while moving to any kitkat rom from previous android versions (..,..., 4.0,....,4.3)
Kitkat roms have some special permissions statements in the updater script (set_metadata). Older recoveries do not have the ability to handle these statements. Update to the newest recovery available for your phone. Otherwise status 7 error cannot be resolved
at last, as you read in every post, i am not responsible for any bricked device.
