I know the current unlocked bootloader causes you to lose 4g.
I'm curious as to why. I've tried searching these forums and googling this, but all I can find is posts and articles that say it simply doesn't work, but never mentioning why. From my Evo 4G days, when they unlocked the bootloder, 4G was never lost and the same is true with the Evo 3D. Revolutionary was able to unlock without affecting 4G. I'm wondering why the photon is different. Does Motorola's bootloader do things differently? Or is something else at play here?
Basically, I am hoping someone can tell me why 4G is lost in the current bootloader.
(P.S. This isn't a complaint or anything. I know there are good devs working on this. I am genuinely curious about why 4G doesn't work with the unlocked bootloader)

When the Evo 4G was originally unlocked, it did kill 4G. Pretty much for the same reason ours does - the bootloader passes off some keys to the 4G radio so that you can connect to the network - ours is missing that part of the hand shake. Jugs has a fix in mind, but is having a hard time coming up with the hardware to build a new bootloader - at least that was the case about 2 weeks ago.
same thing happened with the evo shift. When it was unlocked it took a while to get it figured out how to keep 4g.

That's old news - he always had compatible hardware (but didn't realize it) and then someone gave him a 64-bit OS. Other issues have arisen since then - I just don't think that path will produce anything.

Can someone explain the current situation with 4G not working after unlocking the boot-loader I believe and will that be fixed anytime soon ?
Don't quote my on this, im NOT at all a dev. But i believe its something to do with the RSA Keys getting screwed up when unlocking bootloader, and i know that there are a few devs working on a fix and we generally don't push them for an ETA, they are working on it in their spare time and we are more than thankful they're working on stuff for our photons. Again im not a dev so don't quote me on the RSA Keys, just something i read a while back and *believe* is the issue, if im wrong feel free to correct me and correctly answer the OP's question. If your wanting to have a rom and still have 4g, theres a longer process you can go through to maintain 4g and still have a rom, but is a long process from what ive heard. Ill post link to it below if your interested.
Maintain 4g with Alien(or any rom)

I wouldnt ask for an ETA but the devs are great, it'll be out before you know it!
If I understand correctly, 4G is just Sprint's CDMA WIMax? I'm getting a Photon for use on my carriers GSM network and they don't have LTE or anything (just HSDPA/HSUPA I think).
So losing "4G" when unlocking wouldn't affect me correct?

correct.
hopefully you're not intending on using a US GSM network since they're currently 'locked'...

Hey guys, I'm a noob, please don't hurt me
I'm an American living in Japan and I just bought my first smart phone...the EVO 3D (3G) for AU by KDDI...I'd post a link, but I'm not yet allowed.
Their non-3G network was CDMA...so I assume that their 3G is also CDMA....can anyone confirm that?
Under that assumption (CDMA), we're still waiting for ICS, so I'm wondering what you'd all recommend I upgrade my phone to while I wait. I'm not a fan of the stock Android 2.3 that came on the phone, and I'd really like ICS....but if there is something I could use now, that might be fine with me.
Also, what are the basic steps I need to follow, I found the sticky thread in the dev forum, but I'm not sure what stickies would apply to my situation. I'm guessing I'd have to start with a root kit, and go from there....but please fill in the gaps, thanks

Is there evidence to confirm that ''noobs'' have been mentally assaulted for asking questions on this forum?
Just being playful after watching the required "noob" registration video
Lol I see.
Chances are that you will not be able to activate any CMDA phone from overseas on a network here in the USA. The big networks like verizon and sprint will not allow foreign IMEI numbers to be submitted to their system for activation.
Do you happen to know what frequency the cdma network you came from runs on? Look behind the battery

When I had AU by KDDI when I was living in Japan is was CDMA. As far as I am aware the Japanese version wasn't able to be rooted using the CDMA methods here in the development forum. Also the ROMs here would not work on your device and would actually need to be slightly modified to include files from your device to work, but you don't have an ICS ROM to use for replacing files.

That's kind of the conclusion I came to, after running through all the different root/unlock methods, I came across issues in every single one, and my skill / confidence isn't high enough to really make a go at figuring it out.
Only thing I haven't really attempted is downgrading from hboot 1.5 to 1.4, partially because my software version is different from the instructions, and soft bricking the phone makes me nervous considering the potential incompatibilities.
I think our phone is more or less the same as the sprint phone, just on the Japanese frequency. I'm hoping that the sprint announcement means we will also be getting ICS soon... but who knows
mopho on at&t / t-mobile / straight talk / net 10 / solavei and other gsm providers
Is there an "official" post regarding unlocking this phone for gsm carriers? I put mine on straight talk about a year ago and at the time there was not much out there for this phone but with the help of a number of people on this forum and other forums (I don't remember any names anymore) I was able to completely unlock the phone and put it on straight talk. Since then I have been seeing more people doing it though I don't believe there is any easier way to do it than what I had discovered.
Now I would like to make that information easily accessible to others trying to do the same. But before I do so I want to make sure that I am not wasting my time. Any info out there? How are others doing it?

How did you Do it?
Is it only for 2.3.4 devices?

Mine was 2.3.4 with an ota update to 2.3.5.
Short words I unlocked the bootloader and flashed a kddi radio.
It does break the 4g but personally I don't care. I also rooted mine and flashed cm 10.1 (at the time cm 7) at the same time so I'm not even sure when I unlocked the bootloader if the factory ROM was still intact or not.
The ota update kills the bootloader unlock so i don't think theres any chance of flashing the radios untill thats fixed/hacked.
Thats my understanding right now.

Hey all,
So I've done some searching here, but I cannot find a concise, definitive answer to my questions. I'm buying a first phone for my daughter for Christmas, mainly for use as an MP3 and video player, but also for emergencies. She's still young, so when I say emergency we were leaning towards ONLY FOR A 911 TYPE EMERGENCY, as I believe those are placed even if the phone isn't activated. Anyway, her mom and I are on a GSM carrier so if we did activate it, we'd likely do it there, or a very cheap CDMA provider like Page Plus. So if I buy a phone off eBay or Craigslist today, regardless of whatever HBOOT/BOOTLOADER or ROM it has on it, can I still root it, use HTC Dev to unlock the bootloader, the toolkit to S-OFF, and then flash a 4.X ROM and use GSM if I desire?
Thanks for any help! If this will work then I'll go this route and she'll be very excited!!

The answer is yes, you can do that... the phone will work for E911 calls without being activated. You can also unlock, S-OFF, root, ROM and everything else like you said, although the Rezound is a little more complicated than to S-OFF than just using a toolkit it is doable with some homework and a little Linux knowledge, but to be honest, GSM works fine (Edge data only, 3G/4G higher possible with significant tweaking on some GSM carriers) on the stock 4.5.605.14 ROM.
If you know you will likely be activating this on a GSM carrier, why not get a phone designed for that right off the bat? Several unlocked GSM phones can be purchased for around the same price as the Rez, like the Galaxy Nexus, Sony Xperia S, HTC Sensation, Samsung GS2 GT-I9100 or similar phones. Don't get me wrong, I love the Rezound, but for ease of use on a GSM carrier with full 3G data you migh be better off looking at a phone suited to that purpose.
Yes, it's doable, just know what you are in for...
Thanks you.SO much! I've done wire tricks on some phones before and I think I'm learning that is the challenge here, but I should be good. I appreciate the other thoughts as well. To your question, well, we have poor GSM coverage in a number of spots around here, even we my wife and I using it, and CDMA seems like a good emergency precaution.
Thanks again so much!!

Cool... Note that activating the Rezound on PagePlus requires significant "tweaking" and a donor PagePlus phone to clone the ESN/MEID, PagePlus will not activate the Rezound as it is, neither will any other CDMA carrier but Verizon, and even then they won't do it on a prepaid plan. People have mentioned before that Cricket will do it, but the results have been mixed.
As long as you are aware of the issues and what you might need to do, go for it. Although for use as a video player, I would recommend an extended battery, the screen time on a standard battery is >2 hours. :/

Excellent points. Yeah, I had a S3 on PP for a while and it was a pain - actually CDMA overall is a pain to me so I probably won't do it. Per your advice - looking for an extended battery right now!
Ok so let me begin with saying that I am done with Sprint. The 5.0 update was the last straw for me. Anyway I have two Sprint M7's that are rooted and s-off. Is there really a difference in hardware between them or can I change CIDs/MIDs perhaps flash a TMO RUU and get them to work or will I be simply bricking them and making them unsellable?
Obviously I'd like to keep them because I don't want to buy new phones right now but if I can't I can't. I was just thinking the hardware it self would be the same.
Thanks,
MG

While they are the same in many ways they are different in their radios (CDMA vs GSM) and their partition tables. The different partition tables is what will brick your phones if you try to run RUU's and firmware. About the only thing you can do is unlock the SIM and put in a T-Mobile SIM to get 3G but no 4G or LTE. You check this out here.

Many thanks for the information. Ultimately I guess I'll just pick up a couple of used devices on swappa and move my Sprint devices the same way.
Thank you again.
