Hey all. Great site, I'm just learning my way around my kaiser with all of the great info here.
I had a question I hope someone could answer. I am currently using an unlocked Kaiser on Softbank, but EMOBILE came out with the Kaiser also. The emobile kaiser is on 1.7ghz while the unlocked one i have is on 2.0ghz(please correct me if i'm wrong).
I understand popping in a emobile sim won't work b/c of the difference in hertz. So my question is, is it possible to change the hertz to 1.7Ghz w/some sort of software (ROM or radio etc) or is the hertz hardware/chipset dependant?
Thanks in advance for helping out a newbie

htc Japan Rom
Hmmm. I have not been able to flash this rom successfully. I would like to install the original rom now. Does anyone have the original Japan eMonster eMobile HTC Kaiser Rom? It is not on HTC website.
can somebody help me??
i have problem with emobile s11ht.
this device only work on 1700MHz freq.. can it change to 2100MHz??
coz i can't use the 3G HSDPA by now...
You guys need to flash a radio from Emobile. Either flash an OEM rom from Emobile, or a dumped radio from one.
Since it's so new and rare, there isn't any users with that here, yet since you're the only place in the world using 1700MHz UMTS (besides T-Mobile USA's inactive 3G).
is it mean that there still a chance to flash the radio freq to 2100MHz??

If you don't want to be on Emobile's network ever again, you should then try flashing one of the popular roms on the Kaiser ROM forum.
They all will give you 850/1900/2100MHz radio support, but I don't think you can ever go back to Emobile again unless you can flash an Emobile rom/radio again.
How can we dump our Radios and rebuild it again?

Thanks for the hint. I just bought one of these guys 2 days ago. Haven't done so much. Only Hard-SPL it from the Kaiser Team.
It worked with out a glitch. But, before doing the obvious, turning the JPN version to ENU, I need to make sure that just in case I can resotre that piece of machine back to it's condition.
Question is: How can we (there are some people here in the same situation) dump the rom and have it ready for a re-flash?
Thanks for any advice.
We need a Emobile Radio ROM
Well.
I'm kind of getting annoyed. According to what I have read here, there is a bad chance of bricking the phone if we just flash the phone with the aviable ROM's that we see around here.
I manage to know that, since I come from a different background and I usually take the precaution of reading the technical specifications. So, oh yes, Emobile works with W-CDMA in the 1700 Ghz range.
I definitely need to flash this phone to English (or Spanish) but after backing up the Radio ROM.
Now, how about this:
What if, when cooking a new ROM, we don't include the radio in KaiserKitchen?
I mean, when it comes to compile the packages and all that, what if we omit the Radio File?
In other words: If we omit the radio rom config file from the flash image, will a flashed phone will work?
Any clue?
Today I bought my eMonster after reading these forums for a few weeks.
So far here is where I am at:
KAIS140 MFG
SPL-1.0.Olipof
CPLD-8
Radio 1.71.09.01 (Original was 1 63 08 26)
Currently running RUU_Kaiser_WM6.1_ASIA_WWE_3.10.707.1.YK_Test
Obviously these questions will have some Japanese localization but any help would be great.
Currently I can make calls and be heard and hear the other party.
I have wifi and 3G access access.
However the problems I have are as follows.
The camera no longer works. It simply gives me a black screen.
Audio works when sliding open the phone but if I try to run media player the audio then stops working completely.
It seems there were several applications that came with the original rom that are now lost including the GPS program.
Also it seems that although the OS is in English now input itself seems limited to chinese.
Any tips from users who have an Emonster or can point me in the right direction would be great.
Thank you so much for this great wealth of information.
Candiman in Japan
Ok I've been searching the forums for a while now to find answers to my questions and I've answered a few of them but I think I need a little more advice.
I'm using the HTC Touch Diamond and the Model NO shows DIAM500 on the back I've got MP6950, ROM version is 1.22.557.1, Radio Version 1.03.06F. I'm a CDMA user (Pretty sure anyway) and my carrier is Cellular South.
I love my Diamond it's just my carrier that seems to be a problem. I live out in the boonies so my reception is virtually non-existant at home. Not a major problem but an annoying one. It's not just with the Diamond it's with every cell phone I've ever had. Also the battery life could be better I think, I get about 4 hours with pretty moderate use while I have signal (at work). Haven't really done any tweaking YET but I've started messing around today.
Now this brings me to the reason I'm posting. I was looking into updating my ROM but was not able to download the latest from the HTC site (I figured out why). So as far as ROM's go I'm a little confused with all the custom ROMS posted here, I don't really know which would be best for me and if they will work at all and not screw up my phone. Can anyone offer some advice on what ROM is should use?
And I also want to play around with different Radios because I'm under the impression that it could help my reception issue, and then again it probably won't since I've always had this issue. So has anyone had luck with a certain radio helping poor reception? Is there one that would be better for me than the others?
I'm sure these are fairly regular and annoying questions but I just want to make sure I don't throw away the purchase I just made by updating the ROM and radio.
Most of XDA Forum is not for CDMA.
You can always find custom ROMs. Each ROM is different from the others (included applications and options which affect memory usage and performance). So there really isnt a "best ROM." You can check out the thread for CDMA ROMs and make sure you know how to install new ROMs and that you have the needed applications (HardSPL for GSM I dont know if its the same for CDMA). If you have what it takes you can try several ROMs and radios to find the most suitable one for you. Normally this shouldnt harm your phone unless you dont read well before attempting.
Hope this helps.
I have been searching all week and can find no info on anyone having successfully rooted the Sprint (CDMA) Hero.
I'm sorry to post here but it seems to be the most active android modder board, has any Dev managed to acquire a CDMA hero and is any Dev attempting to root it?
Is this just wishful thinking on my part? I sincerely hope not!
After a week playing with I can say it blows the G1 away! Battery life, speaker quality, form factor, etc, far and away a better more reliable device.
A word of caution to anyone going from the TMobile G1 to the Sprint Hero... DO NOT ATTEMPT TO BACK UP YOUR APPS OR DATA ON THE G1 & THEN RESTORE THEM ON YOUR HERO! YOU WILL LOOSE NETWORK CONNECTION TO SPRINT! I suspect that apps & data downloaded & used thru the TMobile network on your G1 are unable to use a CDMA connection and attempt to modify your system to access the TMobile network. This breaks connectivity and only a wipe has fixed it (hard wipe using the ##786# menu + your individual reset code from Sprint). Your best hope is to re-download your apps. The good news is your download history should show most of your apps and allow you to download them from your CDMA Hero.
Moderators, my sincere apologies if you feel I posted in the wrong forum. I felt it best to reach the active modders I am aware of and offer some transfer advice for those making the switch.
Thanks all,

you're probably in the right forum, since rooting is development. but i do think you should check out the hero forum just in case there's stuff about the Sprint Hero
I dont know much about it but maybe someone can clarify things...now i know cdma is what sprint, verizon, metro, cricket, etc use. Is cdma a hardware type thing or is it a network type thing? And can the sprint hero img be ported and modified to the g1 and somehow allowing it to be flashed to a metro/cricket type service?? Just questions im curious about...
thanks for the response, I agree and posted a different post related only to the Sprint Hero on that forum (hopefully i did not abuse the forum rules, if I did, I understand if a Dev locks or deletes one).

I may be wrong about this but to my knowledge, CDMA is a Network as well as Hardware and software type of thing. When Android was developed it was not capable of running on a CDMA network, one of many things added when Cupcake (firmware 1.5) was relased. CDMA is a network type so GSM only devices will not work on it and as far as I can tell devices built for CDMA are built specifically for that. There is some sort of hardware in there that allows the device to connect to the CDMA network that GSM only devices dont have. (I may be wrong about this though, I also believe it has to do with the radio).
Finally, I dont know what metro or cricket is and I also didn't know that the G1 was on those networks but if it is, I would assume that if those are CDMA networks its not the same G1 that was released on TMO and differers internally in that it can function on a CDMA network. If that is the case then its probably possible. If not then no.
Dont quote me on any of this. I'm not saying this from an experts point of view just from what I have concluded based on what I know about network types, devices and Android.

this is really dumb but has some tried one click root yet? or will that mess up the recovery image leading to a possible brick. becase its running 1.5 not 1.6 right?
I one click rooted my friends g1 the other day and it works fairly well. Don't think you can use the gsm hero root method to root a cdma hero.
Just fyi attempted to root the Sprint Hero using the one click method, but was unsucessful. I couldn't seem to back up the stock image. Any advice?

Hi everyone! My Diamond is running Radio version 1.12. My reception is horrible in my area, where it usually is not. I'm looking for a different radio to try out. I can't seem to find any CDMA radios for the Diamond anywhere. Any help will be greatly appreciated. Thanks! Also, does anyone know of a good Cricket Rom for the Diamond?
Go to Google, type in Roms for cdma htc diamond, then click on the first link (pocketpcGeeks) once the link comes up notice in the top section cdma radios choose one.
Thanks! I'm usually pretty good at seeking out radios and roms, but the diamond doesn't seem to get as much attention as other CDMA phones.
I had my TILT 2 for almost a year now. I don't know what to get. I am kind of scared which ROM to install.

The stock ROMs are generally pretty bloated and prone to freezing. I would recommend that you read the Hard SPL thread, then go ahead and flash the Hard SPL. This will enable to you flash any ROM you like.
Once you have done that first step, just choose a ROM (look over the various choices in this section). You can always flash a different choice later.
WARNING: Make sure your phone is GSM before flashing a ROM from this forum!
^^^^ what he said
You've got nothing to lose and everything to gain by flashing a custom ROM - you can always try another one or go back to stock if you don't like it. Just make sure you back up any data that you want to restore (e.g. contacts, messages etc) before you flash.
All the info you need are in the stickies - e.g. the HardSPL thread for flashing HardSPL, and the "Flashing your First GSM Rhodium ROM" thread.
If you're not sure which ROM to pick, you could always just pick one of the most popular ones to start with, based on the assumption there must be a fairly good reason for those to be the more popular ones.
what I did
Hey
I am about to flash my phone too. I also have it for more then a year ( since last September ) and i did a bit of research just for piece of mind
The most important step is Hard SPL this is so if something goes horribly wrong u can still re-flash it to try and repair the damage ( someone confirm this: there no hardware damage done when u flash , its all just software), besides its also needed in order to flash custom roms aka cooked roms.
For what custom rom to get I did the folowing: sorted the threads based on stats ( posts / views ) and looked at the most popular ones and something struck: Energy rom by NRGZ28 is BY FAR the most popular one, so it must be good for a 1st try then some new unknown cooked rom
Also if you would like to get more info I found this youtube video ( 20 mins / 2 parts ) very informative:
Since I'm new and can't post links search for " Real Time ROM Flashing " and u will find it.

HardSPL removes the SPL lock which normally only allows flashing of ROMs officially released by your carrier. Without it, you won't be flashing anything, except official ROM updates from your carrier. Yes, HardSPL allows you to run Task29, which formats/wipes the memory. And in some cases this can help you recover from a bad flash. Sometimes flashing back to the stock ROM can help you recover as well.

Energy ROM is what I use, and I love it. Its a good tradoff of speed/stability and looks/features. But some feel its not the fastest or most "lightweight" ROM out there. If you want that, some people have recommend Jackos or Valkyrie. Also, lots of people like Deep Shining.
There really is no "best" ROM. It depends on whether you prefer eye candy or speed (or somewhere in the middle), what kind of apps you like to have cooked in, etc.
But I agree to the previous advice given to the OP. Flashing a custom ROM will fix many, many things over the stock ROM. Your phone will be faster, more stable, and have more functionality and features. Figuring out how to flash a custom ROM can be a little intimidating at first. But once you've learned how to do it, its really a snap. And then you will wonder why you ever waited so long to do it! Just make sure you read all the "stickied" guides, read as much as you can about the ROM you are flashing, and follow the instructions carefully.

I recommend Jackos S2 Rom. It is by far the fastest rom i've tried. When you first flash it, it looks very close to a stock rom and it works great just like that and if you want to, you can modify it to your liking. If you want to take a look, you can find the thread here--->http://forum.xda-developers.com/showthread.php?t=632617. If you want to see what it looks like modified, take a look at my profile pic. Jackos rom has been what i've used for the last few months. Like everyone else before me said, do the HSPL before anything.
Thanks everyone. Really really appreciate all the comments. You guys definitely gave me enough ideas and confidence to flash my phone. I can't wait XD

You can also read ROM reviews on The Wingster. But there's no best ROM as everyone said. Find something that fits what you need....
If you want SPEED: Choose a Sense 2.1 ROM or even a ROM without Sense (a.k.a. Titanium)
If you want FEATURES: Choose a Sense 2.5 ROM, with CookieHomeTab or another similar enhancement. They will be slower overall, but they have some neat extra features.
Go with Windows Mobile 6.5.5 unless you really like the Windows Mobile 6.5 design.
Then test out a few ROM's and see what works for you.
If you need any help, in addition to the forums, you can use the Support link on The Wingster and I can help you out. But if you read all of the instructions, everything should work well!
I did my little research and I believe it's a GSM. My phone is TILT 2..is that right?

If you bought your phone from AT&T, then YES it is a Tilt 2, which is GSM.
Your phone is always GSM except if you bought it from Verizon, Sprint, or Telus. Every other provider (T-Mobile, AT&T, and worldwide ones) is GSM!
So if yours is GSM, pick any ROM from the forums here.

Take the back off your phone, remove the battery, and look for some lettering under there. It should say "RHODxxx", where the "xxx" are three digits.
RHOD100, RHOD200, RHOD300 (and variants) are GSM. RHOD400 and RHOD500 are CDMA.

Yea only a dual band phone would still have a slot if it has gsm slot its gsm or dual band point blank... Know what your talking about before you speak..
can a world phone use these roms?
i just got my touch pro 2 off ebay for $200, new in box, which is a pretty good deal. Anyway I want 2 flash one of these roms. The phone's original company is Telus. This phone's marked RH0D500, it's got a GSM slot but is listed as CDMA... (I'm on at&t) From what I read it seems that this has to be treated as a CDMA phone? r there any cdma roms that will still allow me to get corporate emails and use all the good functions of this phone? Oh if anyone's interested the guy i got it from on ebay has like 5 more, but if they're only going to work with CDMA roms then people should probably not buy them for that reason...

As far as I am aware "RHOD00" is not a valid marking. Is that a typo? Or maybe you should look again. It should be RHOD100, RHOD200, RHOD300, RHOD400, RHOD500, and there may be some variants, like RHOD210. But there should be 3 digits after "RHOD" under the battery. Looking around the net, the Telus version should be RHOD500.
All the "CDMA" variants of the Touch Pro 2 actually also have a GSM radio as well (and therefore a SIM slot) since they are intended for "World" use (international travel). This is because CDMA alone is nearly useless for foreign travel, since most countries outside of North America use GSM. So the presence of a SIM slot will not tell you whether its GSM or CDMA.
For the purposes of these forums, the versions of the TP2 that are CDMA/GSM are considered "CDMA" and can only flash the CDMA ROMs. Phones that are solely GSM radio should only be flashed with GSM ROMs. Flashing a GSM ROM to a CDMA/GSM Rhodium will render it inoperative.
The Telus version of the TP2 looks to have the correct GSM bands (850 and 1900 MHz) to work on ATT. But the phone will need to be SIM unlocked, if it isn't already. If you Google around, you will find some posts on the net (and probably on here too), where people have gotten the CDMA/GSM versions to work on AT&T and T-Mobile, so it should work (if SIM unlocked). But it appears you will only have EDGE data speed, not 3G, since the HSDPA/UMTS radios seem to be missing from the Telus version, based on looking at the phone's specs.
You would have been better off buying the ATT version of the phone, the Tilt2. Its the only version that has the necessary hardware to get 3G data speeds on the ATT network. And you should completely understand all the specs before you buy any phone that isn't from your carrier.
