[Motorola Droid RAZR] Ohmster:
I think the antenna is shared by all radio systems in the phone because there is no mention of any additional antennas in the device. The tutorial I used advised caution when taking apart the frame as it is easy to break the tiny wires that connect the antenna, but did not show where that part was. I have done all kinds of electronic repairs in my life but not phones. Those tiny hand camcorders were pretty bad, all micro miniature stuff like the phone but no glue, guitar picks, and spudgers. :p

The repair videos are all a bit different. Some for different models and even the same model comes with internal differences. This one shows the internal parts and a basic outline of how to take it apart. Not recommended or intended as a repair guide, only used to show what is inside a typical phone like ours.

What I don't like about this video is that the video makes dis-assembly appear to be quick and easy. It is NOT

. They do not show the heat gun, the long amount of minutes heating and picking the back off, all the parts inside clean, no tape or "tar" on the battery or back cover. This video gives the impression you can take apart the phone in ten minutes w/out breaking a sweat. Nothing could be further from the truth.

I wish I had your advice and saw the video I now have before I tried to replace the digitizer. I did not have the Torx #3 screwdriver, I did not have the camera bezel sticker, not internal nor external, the internal sticker did start to tear and that is when I called it quits and gently put the phone back together. These phones are all different inside. What you see in one video or tutorial will not work on all phones. Not even the same model. You could clearly see the battery contacts in the video I showed you, but in my previous XT912, there were NO battery contact screws, ribbons, or connections visible, anywhere. I am NOT going to work on a live circuit board like a phone because the chance you will touch something you shouldn't, put it down on something metal, or anything at all to short something on the board is too high a risk w/out disconnecting the battery first. The phone I opened might have had the battery terminals on the back of the board, so, after removing all the screws I could find and were shown in the tutorial I had, I still could not lift the board because there was "one more screw somewhere" and I could not find it. The one behind the camera bezel external sticker.

If you open one of these phones, disconnect the battery immediately before doing anything else!

The following short story tells why.

I worked for a Stereo Repair shop here in South Florida in Boca Raton for ten years. The senior tech, a Vietnamese man named Mr. Thong worked commission and I worked salary. He wanted the best paying jobs so he could make money. He took a 6.1 channel high power Marantz (Bought up by Harmon Kardon) surround sound receiver with a blown power amp. I have done MANY high power amps before to where I must pick bits of charcoal off the board, identify what "they were", and replace them. A blown power amp is a tricky repair because when done, if you missed any tiny issue, even ones that do not show up easily, and power it on, the entire thing blows up and destroys all the hours and parts you put in. This unit was BAD to work on. Everything was on removable modules that once you removed, you could not test electrically because they were no longer attached to the unit. It took him hours and hours to rebuild this power amp, completely blown and a LOT of expensive parts blown. He got it done and put it back in the unit. The final step is to set the bias, or "idle current" of the amp with no signal. As he was doing this, his gold bracelet touched the very edge of the amp module and completely blew the entire thing up in smoke before our eyes! The guy all but broke down and cried. It was a good paying job but the hours of effort just barely make it worth it, ONCE, but for sure not TWICE. So, I never work on live boards anymore unless there is NO alternative and then I am on edge being super careful. :eek:

It became obvious that I needed another screwdriver I did not have and I would need some replacement stickers for the camera, inside and out, and since I did not have them, I stopped.

Opening any Razr phone is difficult

, don't kid yourself. Some of us have the patience, skill, and determination to get this job done, along with all the right parts, and CAN do it, but most cannot. You have the skill, tools, and parts, [MENTION=5695298]googlesstepchild[/MENTION]. That makes you the exception, not the average phone owner or user. If I had to, and had all the necessary tools, stickers, guitar picks, spudgers, and heat gun or 1600 Watt hair dryer, I could get this job done. But it would be slow and painful, the chance for error high, and having to take it back apart again "because I forgot something" would be devastating. (Dam! Forgot to put the battery terminal screws back in now it won't turn on.)

I would have to weigh the time, effort, care, parts, and tools against the cost I would pay to replace it and make a decision. For $100 or less, I would for sure purchase a replacement over fixing it myself. I fix computers, networks, webmaster, web designer, devices, and anything else. I could make enough money to buy a new phone in less time and sweat than it would take to do it myself. :)
