PPCGeeks - FROYO Bypass Exchange Server Policy

First - I take no responsibility if your phone is stolen and all your company secrets get stolen. I have edited the Email.apk to not do anything when asked to set a policy. You will need root to use this, and it only works on Froyo. This was made from the Sapphire email apk.

How?

I decompiled the apk with apktool. I then looked onlien and found the source code for the email app. Within that I found the securitypolicy.java file. I opened it up and compared it to the SecurityPolicy.smali file that apktool made for me.

I found the code in smali and simply changed one "True" to "False", or 1 to 0 (line 151 in java, or 523 in smali). I then rebuilt the apk and lo and behold, no security policy.

Note - I only did this because my exchange policy does not work on Froyo, I am fine with having a policy I just wanted email to work at all, and touchdown basically sucked.

Thanks go to cvpcs, sniffle, and rotordroid for the tips. :-D

I LOVE OPEN SOURCE

JAVA excerpt:

Code:

127        boolean policiesFound = false;

128

129   int minPasswordLength = Integer.MIN_VALUE;

130       int passwordMode = Integer.MIN_VALUE;

131        int maxPasswordFails = Integer.MAX_VALUE;

132        int maxScreenLockTime = Integer.MAX_VALUE;

133       boolean requireRemoteWipe = false;

134

135        Cursor c = mContext.getContentResolver().query(Account.CONTENT_URI,

136               ACCOUNT_SECURITY_PROJECTION, WHERE_ACCOUNT_SECURITY_NONZERO, null, null);

137        try {

138           while (c.moveToNext()) {

139                int flags = c.getInt(ACCOUNT_SECURITY_COLUMN_FLAGS);

140                if (flags != 0) {

141                   PolicySet p = new PolicySet(flags);

142                    minPasswordLength = Math.max(p.mMinPasswordLength, minPasswordLength);

143                    passwordMode  = Math.max(p.mPasswordMode, passwordMode);

144                    if (p.mMaxPasswordFails > 0) {

145                        maxPasswordFails = Math.min(p.mMaxPasswordFails, maxPasswordFails);

146                    }

147                    if (p.mMaxScreenLockTime > 0) {

148                        maxScreenLockTime = Math.min(p.mMaxScreenLockTime, maxScreenLockTime);

149                    }

150                    requireRemoteWipe |= p.mRequireRemoteWipe;

151                    policiesFound = true; //*CHANGE TO FALSE IN SMALI

152                }

153            }

SMALI excerpt:

Code:

520    or-int/2addr v5, v0

521

522    .line 151

523    const/4 v13, 0x0 //*WAS 0x1

524

525    goto :goto_0

Again - Froyo only. Not sure about other roms but since sapphire is built from AOSP and not modified it should work for all froyo roms
