Can't. The V1 has a "write once" firmware. Once burned into the chip, it's there forever.

Actually, there is another channel that has been in place for decades. 462.675 pl 141.3 has been the recognized travel channel for decades. Many repeaters are here, on this frequency/tone.

It would have been a good idea to do your homework before all this. All you are doing is creating confusion.

Update:
I have been in phone and email contact with an agent from the FCC's Portland office, and they are now beginning to investigate the the issue.

Show me a PDF scanned correspondence on FCC letter head stating they won’t.

Yeah, same crappy logic the 11M crowd used to explain away their actions running excessive power and running out of band. A few them don’t think it’s so funny or an academic issue when the FCC was finished with them. When they get annoyed enough they will make an example out someone. You’re betting it won’t be you. 
If you want to play the game of twisting the dragons tail don’t start crying when it gets annoyed enough to turn around and flame you. 

Check the FCC enforcement logs to see what kind of fines they issue. And if you still don’t believe it then all you have to do is ask them. 

Actually, what people refer to as channel 20, has been the travel channel for decades. There is also a designated pl tone. Many open repeaters use this frequency and tone.

Only this "new breed" and some lunatic YouTube er are calling for 19. Personally, I prefer to talk to the old guard anyways.

To restore factory settings, you must download and install a factory image. As always, it is recommended to always upload a factory image to your computer and save it away. A computer is quite obviously required in this case.

The FCC actually doesn't assign the fcc ID. The lab that tests for compliance to fcc standards does. The fcc never sees the product.. There have been cases where the fcc has been made aware of compliance issues and has later pulled a radio's certification.

Why do so many people come to my beloved GMRS and then try to find ways around the rules?  Even if YOU dont like them or YOU think you are so special you need not follow them, those rules are what makes GMRS the best option for the two-way radio community that uses it.
 
Maybe you need to be on ham, where they seem to accept out of the box ideas.  Or maybe you need to join the yahoos on CB 6, where rules dont apply.  But, I feel, GMRS is well crafted for what it does.  I know you will never get caught but you could just accept our rules and be a good radio citizen.

Next time I'm given another "Performance Award" from California Highway Patrol, I'm going to say: "Your beef, officer, is with Kawasaki. These darn Ninjas are too darn fast. I did not do anything that was not in the manual! Just merely kept it at wide-fooking-open!" I'll report here how it went.

Everyone should encourage compliance with the rules. They're not there for an arbitrary reason. The RF spectrum is a limited resource. The rules are set to try and minimize interference between ALL users of the shared resource.
I would encourage you to take a look at the frequency layout for the FRS/GMRS channels, the permitted band widths and power level. What you will immediately notice are the interstitial frequencies lie between the GMRS main channels. In particular the interstitial channels 8 through 14. Those are limited to 0.5 watts and narrow band to minimize interference to the adjacent wide band GMRS repeater input channels.  Even at a narrow band width those still overlap the wide band repeater channels. In fact several repeater owners on this forum have commented about interference from FRS radios buggering up things on their systems even with radios that are complaint with the rules.
 Then there is the issue with dirty radios, the CCR's are the group most  likely to be the offenders. If for example one was transmitting on lets say channel 1, 462.55 MHz, the second harmonic would be at 925.15 MHz, right in the middle of the 900 MHz ISM band.

I had a buddy do the known code plug hack on a cheap Baofeng BF-888S UHF radio to operate on VHF too. It worked. He had a dual band radio that would SIMULTANEOUSLY transmit on the 2M and 70cm band! That ended that experiment quickly.

I received a pair of Tidradio TD-H5 radios today that I ordered a few days ago. They are very similar, but not identical, to the GM-30 model from Radioddity. Basically, the speaker grille on the body of the radio is a little different. That and the TidRadio logo are the only differences I could see on these radios. All the menu/keypad choices appear to be the same. I was also able to successfully program both radios with the Radioddity version of the software. Since I already had this installed on my computer, I gave it a try and it worked as expected. To download the software from TidRadio, I believe you have to create an account on their site in order to access the downloadable file. I did not need to do this since the Radioddity software works as is.
Overall, I think the two-pack of these radios (available on Amazon last I checked) is a great value. For just under $80, I received four batteries and two speaker mics for my existing radios, a programming cable, and a few other accessories. If the batteries were $13 each, the speaker mics $10 each, and the programming cable was $10, those things alone would exceed the cost of the package I ordered. Even without the radios, the package would be a decent value, but the package I received even contained a couple of "spare" radios (if there really is such a thing).
The one thing that is not included is a charging base. Like with the GM-30, the included batteries can be charged with a USB-C cable, which was included. I like charging my radios on a charging base, so I use the TYT UV-88 charging base. The UV-88 uses the same basic case design, so the charging base is compatible with these radios, too. I have also used a Baofeng UV-5R charging base with these radios. While the fit isn't perfect, the batteries will charge properly as long as the radio is making good contact. The LED on the charger will indicate charging status.
As was mentioned earlier in this thread, the radio's antennas are "fixed" and cannot be removed. Not unless you loosen the set screw, that is. When you do that and unscrew the antenna, you'll find the jack on the radio is an SMA female, and requires an SMA male antenna. This means that your typical UV-5R type of antenna won't work, because they are SMA female
If I have anything negative to say about these radios, it's that the belt clip seems a little flimsy. The same is true for the GM-30 and the UV-88, as they all use identical belt clips. There were also only two belt clips included, but since they attach to the batteries, there aren't enough of them for all the included batteries. I prefer the GT-3 type of belt clip, which is a direct replacement for the standard belt clip, so I ordered a 10 pack of the GT-3 belt clips to replace those on all my batteries. The UV-5R belt clips will also work.
In summary, if you need or want a pair of decent GMRS handheld radios, I would recommend the Tidradio TD-H5. They come as a two-pack for about the same price as two of the Radioddity GM-30 radios. The TD-H5 package also includes two extra batteries and two speaker-mics that you do not get when you order two of the GM-30 radios. You can find better handheld radios, but they generally cost at least twice as much as the TD-H5.

Not by regulation. However, hams tend to follow voluntary band plans and gentleman's agreements.

No it is not. Simplex communication on those frequencies *is* illegal. It has been repeatedly explained to you.

Sent from my SM-A125U using Tapatalk

No, the rule states THROUGH a repeater system. Units are limited to test transmissions only otherwise. Using an input frequency for simplex communications is not permitted.

Your interpretation is in error. If a radio is type accepted to operate under one section of the regulations then modifying the radio to operate under a different section of the regulations invalidates the original type acceptance because the radio was not tested under the second set of requirements. It doesn't matter if the modification involved hardware and/or software. Any modification that causes the unit to operate outside its accepted parameters requires the radio to be resubmitted for type acceptance. The FCC Rules and Regulations require 7 volumes to contain them all. Reading one portion of one paragraph under one section does not negate the information or requirements found in the entire body of Title 47 of the US Code.

Done. Thanks!
