Hi All,

My first post on this forum so please go easy on me if I unknowingly violated some rules.

Quick intro : I'm a new member to the forum as well as to this thread. I am learning the ropes on rooting/custom ROMs. Not exactly a dev (though I used to be a dev of a different sort) but happy to help with testing. My first successful root/ROM flash were on my two 3-yr old HTC Desires that I gave away to family members. I then acquired two MMX devices : A90S and A110 for myself and wifey. Despite the "better" screen of A90S, the extra sensors (ambient light) and Corning Glass screen, I must say that from a user-experience perspective wifey's A110 is MUCH better than my A90S. I was fed up with the sluggish response, slow screen refresh times, missed responses on the touch screen, GPS fix issues etc. And thus, my friends, I landed in this forum to root/reflash my A90S.

Below is a summary of my efforts (and this should also answer nil's query) below.

Step 1 : Root your phone using the info on droidiser dot com rootmicromaxA90Showtoguide (sorry being a new user I'm not allowed to post urls yet....a quick google will help you.

Step 2 : Install CWM using the info on droidiser dot com guide-clockworkmod-micromax-a90s

Step 3 : Download OPs ROM on the 1st page of this thread.

Step 4 : Download the META-INF.zip from the 3rd page of this thread

Step 5 : Unzip the ROM in a folder (let's call it "Stock On Fire V1" folder). It should contain two folders : system and META-INF

Step 6 : Delete the META-INF folder

Step 7 : Extract the META-INF.zip from Step 4. It will extract to a folder called META-INF folder. Inside this META-INF folder, you will see

another

META-INF folder containing com, CERT.RSA, CERT.SF,MANIFEST.MF.

Step 8 : Copy the META-INF folder containing com, CERT.RSA etc to the "Stock On Fire V1" folder

Step 9 : Now you should see two folders under "Stock On Fire V1" : system, META-INF

Step 10 : Select these two folder and add to zip file. DO NO try to zip the "Stock On Fire V1" folder. The final zip file should contain the system and META-INF folders in the root..not under another subdirectory.

Use the zip file from Step 10 and follow the steps given by OP on Page 1 and it would flash like a charm.

Most of the issues people have complained about are due to the above. Even I took multiple attempts to get the above right.

King ACE,

Thanks for this wonderful ROM. After flashing it most of my issues with A90S being sluggish, unresponsive have gone away !!

Request you to replace the ROM available for download with one that has the correct META-INF and most of the ppl's issues would go away.

Also, eagerly awaiting for V2. Can you please look at removing the MMX bloatware and providing the apks as a separate pack if someone wants them? I use my MMX outside India and thus find most of these pretty useless.

Btw, can anyone confirm the GPS fix issue is still there or resolved? I still can't seem to get it to work despite trying with GPSfix.

The structure of the ROM zip file should be as follows :

zip file containing two folders

in the root

(not in another folder) : system, META-INF

The META-INF above should be the new META-INF and should have the following :

META-INF>com,CERT.RSA,CERT.SF,MANIFEST.MF

(not META-INF>META-INF>com,CERT.RSA,CERT.SF,MANIFEST.MF)

Take care of the above while zipping/unzipping and the ROM would work fine.

Also remember to wipe data/factory reset, wipe cache, format /system, mount /system before flashing.
