Root CWM V5.0.2.8 for MMX A87

Hello,

Now after so many days of trial and error...

I have finally managed to get a working CWM on the phone.

I have tested it to a certain extent.. Works fine on my phone but if you do find any bugs let me know and I will try to fix them.

Before you download. Let me tell you that I am not a developer, I am just a beginner and I had to spend 3 weeks to get this working.

I would request you all to not post it on other sites and forums... You can post links to this thread..

Check the next post for the link


If you like to show your appreciation, click the THANKS button.
 
Here is the link - http://www.mediafire.com/?4z4itcg167fwnzi

As soon as you boot into recovery, Use the volume button to scroll through the list thrice...

Press the volume up button to keep scrolling.. Once you reach the last option at the bottom, keep pressing the button and you will go to the first option.. continue scrolling and once you complete scrolling thrice, You will see the text "Back button enabled". Thats it. You now have a working CWM...

Like my work, hit the thanks button.

Wanna share it -- Feel free, post links to this thread.
 
Hey itzmiandy, i saw it somewhere just give me some time. ill get back to you.

By the way did u try the twrp custom recovery development. i saw they had a live chat facility and pretty friendly people. Me being newbie couldnt do much but i am sure its worth a try.
 
:hello: Atlast you guys woke up..

Alright folks here is the deal.

This is a forum where we share knowledge and help each others out.

We need to pitch in with whatever little we can do to help so everyone can learn from each other.

Now that we know existing/building CWM recoveries does not work on our phones, we need to build one from source.

I am downloading 26 GB of source files on my Linux system and will try building a recovery from source.

Now the challenge is to modify the binary file in the existing recovery "Android recovery 3e". This mod is to disable the signature verification.

A lot of developers have done it for samsung phones and they were then able to flash CWM recovery on their phones.

To make things easier for you, I have unpacked recovery.img

Here is the link to the recovery binary - recovery

The sooner we find a solution, the sooner we get ICS on our phones:D
 
man exciting. lets get this going . there r lots of views for the thread mate so everyone is keen.

this is challenging and i like the way u said we will get ICS quickly

long back I have used hex editor to crack some softwares.

Here is the basic tutorial for hex editor usage:
Reverse Engineering 101 ( Using a Hex Editor to Find Passwords ) Tutorial.mp4 - YouTube

I found some interesting points on how to bypass signature, haven't tried but it might be helpful for you. Here is the link:
How to Fix / Bypass Android No Signature, Verification Failed Error


Thanks for trying to break MM A87

Hey bro, thanks for the links. We will not be able to boot in to CWM recovery.. so the second link is not of much help.
 
Maybe hex editor can be used to compare the recovery binary file and another file with the signature verification removed. do we have a file with the signature verification codes removed?

I was waiting for someone to ask...

here is the link. - Recovery_mod.zip

Those are for samsung..

The file offsets will be different in our recovery due to different compiler version, options etc but we can use the strings in IDA as guide to the region that needs to be changed.

All thanks to untermensch in XDA for his work and guide..
 
hey itzmiandy, not a popular phone bro. so not many people keen with the development. but i really think with a custom rom this phone would be excellent.

We can do it. I am working on the recovery files that you gave me. With IDA assembler the data can be analysed. just some time mate. you know i am a newbie here. I should get there in time.
 
hello guys, i have the fone rooted..have working adb connection..but i donot know much of android development...but am willing to do testing ..

Cool bro, Let me know if you manage to crack something..
 
I build recovery from source and it had the same problem.

A white flashing screen followed by a solid white screen.

Any ideas to fix it?
 
got this phone for my sis. and had to root it to free some space and save RAM

itzmiandy@ bro ask mastermind1024/ninad to help you create modified custom rom [boot image] to be flashed with sp flash tool and include recovery in it so that any further rom can be used with recovery

we have already rooted the device
we have rom dump[i am not sure but it can be done easily]

a modified boot.img including recovery,root can open gates for further development

P.S. i am not a developer also i cant test these rom on my sis phone [sorry for that ... she wont let me do all sort of testing on her phone]

As far as my knowledge goes, SP tool works only for MTK devices :-(
 
Did anybody even notice that the boot.img is a standard android image file but the recovery.img is a zimage???

If there are any of you developing CWM here is a tip.

When you unpack recovery.img you will find busybox already in there in the sbin folder. However if you do a ln -s busybox ./sh and repack it, it does not work. You get a white flashing screen.

I had the same when i used a recovery developed from the koush clockwork builder. When i pressed the volume keys it showed some flickering. I am guessing it could be some resolution changes or graphic error. In koush builder it said we could make changes to graphics.c i dont know much about how to do that.

I thought of it at the beginning but NO...

It has nothing to do with graphics.c.

The problem is with the zimage..

@ everyone,

Can you boot the phone into the stock recovery mode, connect the phone to the computer and do a 'adb devices'

Once you see your device getting listed, do "adb shell" and post the results here...

Please Urgent...
