[Motorola Droid RAZR] Ohmster:
Mr Chen! Twice in one week I hear from my dear friend. How delightful! :)

Agreed, the "How To" for teachme is way over his head. I did it as a challenge when Brian Hughes "thought" I performed this on my own phone. So I decided to find out exactly how one does perform this MAC change permanently and had to do a lot of figuring on my own by using some of the material on the Texas Instruments page because the device is different, but the file and purpose were the same. It was a lot harder than I thought. Those "instructions" were not exactly written for what I needed or had in mind. So I actually did a search on the bin file, and searched out each segment of my wifi MAC until I found it, then continued the search to make sure the same data byte was not duplicated elsewhere in the file. I did this very same repetitive search for each and every one of the 6 parts of the MAC address. The data did line up with the Ti instruction page offsets and clearly, I had found my wifi MAC. Now I know how to change it and run wifical.sh to commit the change to the device. In order to make this search and replace guide clear to other people reading it, I color coded each segment of the MAC address and colored the corresponding bits in the file with the same color. Thus making a How-To that anyone who could use a hex editor could understand. Looks like you were able to understand it, yes Mr. Chen? :)

Your opinion and recommendation that teachme send us the requisite MAC address so it could be done for him was absolutely correct. There is no way that teachme would have been able to "comfortably" (if at all) do that on his own. ;)

I would love to see your How-To if you ever get the time to make one, Mr. Chen. You are very welcome to use my "chart" or anything published by me to assist you in creating your own help file and can use the image in your How-To if you like.

You know, I have a lot to learn about Safe Strap from a technical point of view, not as an end user. It took me nearly forever to learn how it uses internal storage for the slots, let alone all the details on how it works and where it keeps and places files. Your explanation is pure gold and will go into my own collection of posts that cover almost any subject on romming, rooting, and flashing that I have. Thank you very much, Mr. Chen.

Oh that is awful that you lost your /pds folder. Yes, it happened to me on my last phone. The phone still works but you are severely hampered with certain technical issues because of the loss. I was willing to offer up my own /pds folder to anyone that lost their own. However, there are 2 points to address.

You have an XT910 and the contents may differ from an XT912 like I have.

My phone IP & MAC addresses may be in those folders and need to be changed to meet your requirements.

So far as an XT910 /pds folder goes, we can probably get Casper or Welder to donate theirs. Zip it up and attach to a post. You already know how to change the wifi MAC so you can handle that. Then it would be a matter of checking the other things in "About Phone" to see if they match up or must also be changed. I see no real danger of inserting someone else's /pds folder into your phone other than inaccurate address or ID information. Once the proper files are edited, you should be good to go. Even if things did not work out for you, you could always use the File Manager in Safe Strap to delete the /pds folder or move it to your ext-sdcard to deactivate it.

Of course, before doing anything like this, precautions must be taken. Backup everything you can on your phone first! Backup all roms, all apps in Titanium Backup, and when in Safe Strap, you can use the Mount button to mount to external USB, meaning you can plug the phone into your PC with USB and get the internal and external sdcards to open in Explorer windows for copying, pasting, moving, or even formatting. Once everything is double checked, you would be ready to proceed.

When I backed up my /pds folder, I also made a list of every file and folder in it with owner, group, and permissions assigned to each file and folder. In the event I had to restore this crucial folder from a Windows zip file for fear that the permissions would be inaccurate. To create this very accurate list of permissions, I did an "ls -R" within the Terminal Emulator window on the phone and redirected it to a text file for safekeeping. I will attach pds.txt to this post so that you have an accurate list of files, folders, and permissions for this crucial folder.

Mr. Chen, I really think that if you get a copy of /pds from another XT910 owner, you would be able to use it and make it work on your own phone. Should we put out a call to the group to see if we can get one?

[MENTION=240993]casper[/MENTION] [MENTION=5057697]welder73[/MENTION] or anyone else. Can you please copy your /pds folder from the very root of your phone to PC and zip it up, then attache to a post to help out Mr. Chen? This would very much benefit you all as Mr. Chen, as an IT Engineer of 10+ years has the skill, experience, and expertise to modify this crucial folder to work on any phone, that is the intended goal, anyway. This crucial folder often gets wiped by accident when flashing new roms and this discovery could help many others who have lost this crucial folder. Any help that you require in capturing, zipping, and uploading this folder will be supplied upon request. Thank you all XT910 owners very much.

Man, you can forget about [MENTION=4161843]ktimque[/MENTION] updating the installation or any other pages in this thread. When he first took the torch from [MENTION=2225214]hakarune[/MENTION] he did msg me with some questions about what has changed in cm11 for the guide on page 1. That guide is so outdated it is ridiculous. We no longer need all that wiping and patching, it is really quite simple now, root, install Safe Strap, flash cm11 and pa-gapps, reboot. If you guys are listening, we would like to assist in updating the How To on page one of this thread. Thank you.

I think that about covers everything for right now. I do hope that one day in the future, we can stop in a small restaurant and perhaps enjoy lunch together. That would really make my day complete! Take care, Mr. Chen! :D
