Hi,
What is the difference between A8181 and A8183? I have a AMOLED HTC Desire and recently debranded it to Stock HTC WWE ROM and noticed that my Model Number is: HTC Desire A8181, I am sure it was 'HTC Bravo' before on T-MOBILE UK ROM.
Anyways, when I search A8183 on the net, this model is often referred to the SLCD model and when searching A8181 it's AMOLED. Have I made a mistake in flashing the wrong ROM for my device?
Key reference: link
Please advise me.
Thank you.
The A8181 and A8183 are essentially identical, except for differences in hardware between the two and the radio bands that they support 3G on. If you are on Telstra in Australia, Rogers in Canada, or AT&T in the US, you need an A8183 otherwise you need an A8181.
On the forum, in the Android Development section, you will find that ROMs are model specific (GSM ROMs for A8181 devices, and CDMA ROMs for A8183 devices), and with radio upgrades, you may find certain versions work better than others depending on carrier/area.

Incorrect. 8183 is GSM.

Apologies... yes, A8183 is also GSM. That's what i get for not being able to think straight and staying up late!

Thank you both.
Oh, and the 8183 comes in both amoled (early models) as well as SLCD (current models), so the screen isn't device sepcific, but rather age specific.

Is there any obvious difference in screen quality between the two screen types?
(Sorry, I know this post is old, but thought it easier than making a whole new post about this)

According to my "about phone", phone identity, model number, my device model is A8181.
As far as I know, there is A8381 (or something like that too).
Can someone share what is the difference between this two models?
Thanks.
I think it's to do with differentiating between hardware versions. Different markets have different standards, i.e. the US and Japan use a different UTMS frequency for maobile data to the ROW thus might need a slightly different hardware version for full compatibility. Or, there may be a slightly different hardware versions over the life of a product which may come about through the guise of "continuous product improvement".

Thanks alot for clearing this up for me
8181 in Australia
I,m in Australia, my desire is a 8181, seems to work like a dream, if the other version is better for Australia then I,d like to know more
I believe you only need the A8183 in Australia if you want to use the phone on Telstra.

Hi,
I have tried searching the forums but I can't seem to find whether the custom ROMs will work with A8181 or A8183.
Thanks!

I've flashed DeFrost and OpenDesire and I'm having no problems (got an A8183).
As for the difference between the A8181 and A8183, does anybody know if there's a physical hardware difference between the two?
If it's just a software problem, theoretically, couldn't the radio rom be hacked to use all 3 bands?
it's hardware
Both work fine in Australia on any carrier.
The A8181 works on the 2100mhz frequency which all AUS carriers work on (yes - even Telstra).
The A8183 works on the 850mhz frequency, which is the Telstra NextG frequency, so either model will work on Telstra.
Main advantages of NextG (as claimed by Telstra) are faster data speeds and better coverage compared to 2100mhz.
So, A8181 for 3g and A8183 for NextG.
ROMs arent model specific, however with radio upgrades you may find some suit your carrier/area better than others.
I am using a Telstra Desire with an Optus sim and it works fine. I still get H for connection and it's pretty fast internet. When I have full coverage webpages load in just a second or so, and it's more then fast enough to stream movies and music.
okay, so i've got a newbie question to ask.....mine's A8181, and im in toronto using Rogers, but so far i've been using wifi only, no 3G data plan for me as of now......my question is, is it totally unusable for the 3G with Rogers? cuzi heard ppl told me its still usable, but with a little bit performance deduction....perhaps as not 100% fast as it should be.....anyone got a clue for me?
I've been thinking about getting this unlocked model that is compatible with AT&T 3G. I was wondering if anyone here has done this, and is there a way to get a sort "US-ified" version of the official HTC ROM that can receive OTA updates.
Thanks.
i'm currently using the A8183 in Canada on the Rogers network, which uses the same freq as AT&T for 3g, works great for me. however, if you wait prob a month or so (or maybe even sooner) Telus/Bell will release a NAM of the Desire, they also use the same freq for 3g (Bell, Telus, Fido, Rogers, and AT&T all use 850/1900 for 3g)
i'm using an A8183 (Telstra) HTC Desire on AT&T... in my opinion, you won't get a US-type ROM without rooting and installing one of the custom ROMs... i'm using the DJDroid Froyo w/Sense ROM and have not had any problems. personally, i don't worry about OTA updates because i'll get them on xda first.
I too have an a8183 on at&t. The only problem is that at&t does operate on 1900 mhz for 3g, but 850 mhz will not completely fallout till the end of the 2010. So If you live in nc, ga, sc, or va . The southeast market. You won't have the 3g because they currently run 1900 mhz 3g. I can still stream music on edge pulling 100 kbs up and down.
Patience is a virtue and locally in NC I have seen an internal ATT map showing many cell site upgrades complete, but they have not switched it on yet for 850mhz.
Latest news is for Atlanta and Manhattan switched on.

Thanks guys. I think what I'm going to do is wait and see if AT&T comes out with their own version of the Desire this month, like has been rumored.
At&t will not get the desire. I am an employee and waited and waited. We may get the rumored dual core Qualcomm since it was just delivered to HTC and the incredible went to Verizon. So we are next for the bigger one.
There is a Samsung coming out Sunday, but I just love the support for HTC with xda. You will have 850mhz umts by the end of the year if you live in a 3g area.
What state are you in?

I think I may still wait to see what AT&T comes out with from HTC, even if it isn't the Desire. The new Samsung Galaxy S phone on AT&T looks nice, except for the fact that it doesn't have a camera flash. That's a big omission in my opinion.
I'm in Connecticut, where we already have 850 mhz.
Go for it , because gingerbread 3.0 will be a whole new class of devices. Maybe even dedicated graphics cards. But thats about a year away.
Plus the imei is not registered with ATT so you can get away with a 15 dollar data plan. Dude you got 850mhz. Shazam......
Sent from my HTC Desire using XDA App
it's probably a good idea to wait. i got an a8183 a couple months ago, i love it but the only reason i got it was because my trusty tilt running eclair was run over and for some reason i didn't want to get a nexus (which is probably what i should have gotten). i was banking on the tilt lasting about another year so i could get on the dual core wagon but no dice. don't get me wrong, i love my desire but with all the cool guy stuff just over the horizon i wish at&t would have released the aria a couple months earlier, so i could have bought a less expensive phone to hold me over til the new stuff came out.

I see that Telus just announced they're getting the Desire soon, which will probably run on 850mhz and 1900mhz. So, I'll see what AT&T does and if nothing and the Telus version comes out, I'll get that one.
I live in North Carolina. How can you tell if they are using the 1900 or 850 band for 3g? I found someone selling the HTC Desire for $500/shipped and was going to get it until I saw this thread. Didn't know if there is a way to find out where AT&T had gone to 850 for 3G bands.
RTP area here and we are definitely on 1900 mhz, and will be strictly 850 mhz by the end of the year. Edge is pulling about 100 kbs up and down.

Well, there is 2 models of Desire as far as I know; the A8181 (Not AT&T 3G compatible) and the A8183 (Telstra version, compatible with AT&T 3G). If your Desire isn't working with AT&T, then chances are it's an A8181.

Remove your battery and on the phone lists the model number next to the imei. A8183 is what you need outside of the southeast market until 2011.

There appear to be 3 models of the 'classic' Desire:
A8181 - Euro version with 900mhz/2100mhz UMTS/WCDMA
A8182 - North American version with SLCD screen and 850mhz/1900mhz UMTS/WCDMA
A8183 - North American / Australian version with AMOLED screen and 850mhz/1900mhz UMTS/WCDMA
Hope that helps!
I'm using a htc desire A8183 in Colombia, and it works beautifully with excellent 3G network speed of navigation and a month ago I got the ota update for Android 2.2 Froy. I'm really happy with the phone

Actually, all the A8183's in Australia being sold have SLCD screens, not AMOLED.

I noticed everything in this Desire section is related to the GSM Desire. Are there any custom ROMs yet for the CDMA Desire? I was to get the Clockworkmod recovery to boot from an update.zip and that appears to work ok but every Desire ROM I've tried refuses to boot.
I can't seem to find much information at all about the CDMA Desire via searching the forums or just searching on Google. From what I can tell all the hardware specifications are the same except for the radio (CDMA vs GSM). Might it be possible that current ROMs built for the GSM Desire will work for the CDMA version if a custom kernel for CDMA is compiled?
I wasn't even aware that a CDMA Desire existed!

Dave
There was an Australian desire version. That's the only I can think about.
There is supposed to be an US version, but I think it's not available yet.

I have a desire in South Korea that has a WCDMA sim card in it running on the SK Telecom network. Are we saying that android 2.2 port that the devs here created will only work on GSM desires? Also, does anyone know if I use an unlock code on my phone if it disrupt my service?
Sounds to me like you have a regular Desire because WCDMA is part of the GSM standard for 3G!
Regards,
Dave
No CDMA Desire out there. You guys already have the Incredible, the Evo and Droid X that don't work anywhere else but America and you want more still?
Like Dave says WCDMA is a different variant/name of the 3G network.
Strange that the Roms aren't working for you. The innards should be the same inside.

I have a CDMA Desire. It's a test unit for one of the smaller carriers in the states (I'm not in the states) I'm using as an internet tablet/android plaything. If you guys want to know anything about it let me know.
The CDMA Desire has launched on U.S. regional carrier U.S. Cellular. Here's a link. I'll be picking one up tomorrow.

The Telus Touch Pro 2 is a CDMA phone and so is the USC version. So it makes sense the ROMs would be compatible.
The Telus Desire is a GSM/HSPA phone - Telus launched an HSPA network in late 2009 and they're slowly trying to make their old CDMA network irrelevant. I can almost certainly guarantee you that his Desire ROM *won't* work on a CDMA Desire.
Well that would suck!

I am pretty sure we will not see any custom roms for our desires. However, thats not all that bad. If we can just get root. Then we can uninstall what we want, tweak what we want, Install wifi teather, etc..
I still think we can be rooted in almost the same manner as the incredible. Damn near exactly the same phone.
Anyone know how to get ahold of the unrevoked team? maybe they can help. They seem to root everything.

I know both are the same Android platform, however, I’d like to know which HTC model phone is as “exactly” the same as the “G2” with the CDMA radio. (Not GSM)
Exact same hi-cap batteries and battery covers, holsters, cases etc. Is there such a thing?
My reason? …moving from TMO to Sprint after 14 years. A CDMA version of the Desire Z/G2 would be nice, if HTC makes one that is a mirror image in CDMA radio format.
Thanks for any input,

Hi my plushies
Anyways. I just got a Desire HD! YAY ME!
Being a Desire owner for 2 years and seeing a lot of great development on the HD, i'd give it a go. So far seems good, though i like the AMOLED a bit more imo
So my first boot after getting it from retailer, it boots with T-Mobile logo. That means its from USA right? Is my phone then an Inspire or a Ace? Afaik, the Inspire is the american version?
The weird part is, i got the T-Mobile one because the other one (a danish one WWE), was send for repair and i recieved this instead.
Will this affect anything? And how the *** do i figure out of its an Inspire or Ace?!
**Btw, i did do my search first lol
**Is it on the bootloader? I saw an "Ace" in there, but wasn't sure if everyone DHD had that name
*2. edit* Lol apparently i've used the wrong terms. So, Desire HD or Inspire (Apparently their all Ace (As in vendor Ace, like the Desire -> Vendor Bravo))
Inspire is the 4g version DHD was not.
also check the "full" spec list at the bottom of this page
http://www.differencebetween.com/difference-between-htc-inspire-4g-and-vs-htc-desire-hd/
I've got a german t-mobile branded phone so i'd never be sure where it's from
but yes: DHD is the HSPA version, Inspire 4G is the 4G version (LTE? HSPA+? no clue)
My phone is an American inspire that i bought unlocked online... its actually an ATT phone and not tmobile. If your phone is a Tmobile then its def not american but probably from some other countey instead. Another way to find out is by seeing if you get access to 3g in yoir country. Because att uses frequencies that are different from most other countries around the world, the american Inspire doesnt get access to 3g data in most countries. Apart from that its practicaly the same phone hope this helpzs

There are basically 3 versions of the Desire HD.
First is the European/Asian version. It is model A9191 and has high speed data bands of 900/2100. It can be branded or non branded but they are all the same physically. If it says T-mobile on it then it is a European version branded to T-mobile.
2nd is the Telus Desire HD from Canada. It is model A9192 and has high speed data bands of 850/1900. It has no logo denoting it as a branded phone. It also has a second mic by the camera flash used for noise reduction.
3rd is the Inspire 4G from ATT in the USA. It is also model A9192. Physically it is exactly like the Telus Desire HD except it has ATT branding logos on the phone.
All 3 phones are HSPDA compatible. All 3 have the same size memory. All three have the same LCD. In terms of getting at least 3G, if you live in Europe you want the A9191. The A9192 is mainly for North America/parts of South America and can be used in parts of Australia on the Telstra network.
Hi I currently have a A9191 running CM7.2.
When I purchased this phone (in Australia) I was originally on the Vodafone network & I'm now on Telstra NextG (850) - but for high speed data it can only get the "3" network = 2100.
I wanted to know if it is possible to load on the A9192 baseband to "activate" / change to the high speed data bands of 850/1900? Or if there is any other mod to do this?
Or is the physical hardware of the A9191 only capable of the high speed data bands of 900/2100?
Any help or advise would be much appreciated

Thanks Teichopsia,
Looking at this thread, it looks like he was trying to get 4G (inspire4G) out of a 3G device, which I'd say is even harder than just switching bands.
But it doesn't mention anything about the A9192 vs A9291.
Even Qualcomm's site doesn't list a A9192.
I agree it does look like a potentially hardware thing though - i.e. potentially different radio hardware / antenna / firmware... but I don't specifically see this detailed anywhere. Looking to see something that says it is different physical hardware.
The theory I'd like to validate - both Desire HDs use the same MSM8255 chipset, & perhaps you can make a A9191 to a A9292 with flashing the right firmware.
Going to reply to the thread you sent to see if they had any further luck.
Kind Regards,
David.
