So I've had my 7135 for almost 2 years now. I've not had any major problems with it, until recently. In the last 2 weeks, it's been turning itself off nearly every time after every call, and also at random. I've missed a lot of calls because of this.
Based on what some of the people here have been saying, I figured it could be the radio board disconnecting from the mainboard. So I popped it open:

I thought that the connector seen here could be the problem:
So I cleaned it all out with canned air, and pressed the pieces securely back together. I reassembled the phone, restored my data, and so far it's been working great. My "0" key works better now too since I cleaned it out!
It's not too difficult to do, and if you're no longer under warranty I highly recommend doing this!
Alright, bad news, it turned itself off once today.
However, I just noticed that the backplate that holds my battery in has gotten rather loose.
Based on what i've heard from other people on this site about pressing a piece of paper on the battery cover, I placed a piece of paper between the battery and the phone, and then inserted a brand-new backplate with a strong clip.
The battery cover is loose on all 7135s - even new ones. This is not the problem with poor battery contact. The battery contacts in the phone and on the battery are gold-plated. This provides low contact resistance and minimizes oxidation of the contacts. However, even gold-plated contacts can get dirty over time and may fail to make a good electrical connection. Any phone that has the original battery in it that has never been removed can develop this kind of problem. I would recommend simply removing the batttey and cleaning both the phone and battery contacts. Do not use an abrasive cleaning method. The gold-plating is very thin. A pencil eraser works well without doing any damage.
I wasn't talking about poor battery contact -- I meant that when the battery isn't securely in the phone, it doesn't press up against the back of the radio board, and therefore can't help keep the radio board connected with the motherboard.
sorry for the hijack,btw. sounds like a cool app, wish I would have realized it existed when i was using my 7135. i used the onscreen keyboard all the time, but hated loosing the screen space.

Avatar-X is 100% correct. Anyone who works with electronic devices knows that by far the least reliable part of the device is the connectors. My 7135 got the SCRP after being manhandled by my friend's 4 year old son who was playing Tetris on it. No amount of hard and soft resets or cleaning battery contacts made any difference. I did exactly as A-X suggested and all is fine now. The whole job took 5 minutes.
I never thought that battery connections could make a difference as some have suggested. Putting a piece of paper behind the battery just puts more pressure on the circuit board when you put the battery cover back on, and for a lucky few that is enough to make the multi-pin connector make acceptable contact again.

Hey Mr X
Sorry to change the subject a bit, but would mind posting your stamp, or give us the link to where you got it. PS

That's a good lookin stamp! I might give it a try. What layout memo file did you use? We should probably start a new thread on this aside... I thinks its been years since I seen a discussion of stamps, millikeys/fitally or otherwise.

PS You reponded pretty quick and in the middle of the night for where you are... don't you sleep?

Interesting. As a multiple victim of the zero key failure (about every 4 months), I'd like to be able to open mine up and clean it out too. Is there a discussion/instructions somewhere about how to do that? THANKS>
1. Back up your phone with backupbuddy or similar.
2. Remove battery.
3. Unscrew the antenna carefully until it comes out.
4. Using a small torx screwdriver (make sure you have the correct one), unscrew the four screws on the back of the case.
5. Very very carefully, pull the case off. You may need to pry a little at the edges. Don't put too much pressure.
6. You will see the back of the radio board. You can carefully pull it up.
7. Underneath the radio board you will find a metal EM shield. This should come off easily.
8. Very gently, remove the mainboard. Note that the side buttons and headphone jack will make it difficult -- make sure to disengage them carefully. Note that the mainboard is connected with plastic ribbon cable to the screen at the top -- Do NOT pull on this, it will tear and your phone will be worthless. Treat it like a hinge.
9. Remove the button pad and clean it carefully. Clean the bottom of the mainboard's contacts with a soft cloth and some alchohol.
10. Carefully re-assemble everything. Push down good on the place where the connector between the radio board and the mainboard is. Don't forget about the RF shield. Don't forget the antenna.
11. Reinstall the battery and the phone will power on. Restore your data.
WARNING: You will be working with incredibly complicated, static-sensitive, tiny circuitry. If you have any doubts about your ability to perform this, it's best not to do it. You should probably wear an anti-static wristband while doing this, connected to a grounded source.

Good luck!
Very good instructions, just a couple of comments.
3. I didn't do this, it wasn't necessary at least on my phone.
6. Before step 6, you need to remove 2 more screws (same size as 4 outer screws) that hold the "sandwich" of the RF board, RF shield and main board together. At least on my phone.
Also, while A-X is 100% right about using a static wrist guard, I didn't and my 7135 lived to tell the tale. And in step 4, I didn't have the tiny Torx screwdriver, so I just used a small blade jeweler's screwdriver. Not recommended since it could strip the screw heads, but again I dodged the bullet.
Further to my previous post - I would get SRCP after a day or two, then I'd do the fix again, SRCP gone, repeat, each time SRCP came back sooner. Finally I gave up, swallowed my pride, made the call to Verizon and got my free Treo 650. Sorry to desert you guys - and on my 100th post!
While there's a ton written about 7135 vs. 650, I can't help but add my 2 cents:
Screen, processor speed and bluetooth connectivity (Hotsync, file transfer and DUN via Shadowmite hack) are awesome. So is VoiceDial - works great for all your contacts with NO TRAINING.
Virtual keypad, lack of hard pause for dialing passwords and lack of integrated voice recorder (that works even when you're on the phone) stink.
I think I have finessed VZW to allow me MOU for data charges, but we'll see if I have to make my monthly call to VZW to remove PAYG data charges.
Possible solution to SRCP / Random Offs!
