Hello,
I'm quite new with android devices and have read several topics here, but still have some questions. So I do apologize if it's answered or explained already somewhere, but I haven't found it.
Let me first explain what my assumption was and what are now.
1. HTC kernel/update - So HTC is getting generic android from google and make and add their modifications.
- Maybe there are some difference in the ROMs and/or devises for different regions like Europe, Asia, America ... , but not sure if it's correct and why it is needed at all, unless it is something specific with network carriers
- I do not understand the reason to have a different ROM or OAU per network carrier unless that the update should be approved by the carrier /why needed/. If so, what about the countries and carriers not available on htcdev site, that means such operators and countries use generic regional like WWE Eastern Europe or EU, but who is approving them in that case
- currently there are quite big difference to updates and versions available for different regions and carrier operators
2. Is there any way to get stock/original ROMs
So till recently I believed there is a generic ROM and depending on your home network/operator/carrier you got OAU or not, but it turned out that is completely wrong. It seems the phone is preloaded with a specific ROM made for specific operator or more generic one like EU, and depending on those ROM you have particular update or not.
- still not sure what the reason for this is
3. What is the meaning of CID on particular ROM, isn't it just a simple configuration in a configuration file into ROM.
I thought if you have stock ROM with different CID inside than current one, you should be able to flash the phone with it and it should work. Possible issues should be only with network carrier , but all the rest should work, isn't that correct.
4. If you flash you phone would your IMEI and/or CID change or the CID is hw locked and not into ROM
5. Is there any way to change the CID
6. I've read a lot in the forum in regards to ROMs, but still not clear
- is there any really original stock ROMs
- why people having issues with stock ROM depending on their current CID, and the ROM is working with some and doesn't with others
- what is the problem with OAU after change of the ROM with stock one
7. Is it possible to make a image of my phones without rooting them
8. What's the problem to get the ROM from one phone and put it in another as both are original coming from HTC with devices
I do not want to root the device or put custom ROM for now, but interested in having original HTC ROM with different CID than the current one, and trying to understand the setup and how it is working and how can it be done.
I own two Desire X which happened to be with different ROMs and CIDs, one Orange CH, the other T-Mobile PL, so there are some difference, so I would prefer to have them both identical may be EU or Eastern Europe ROMs inside and have the corresponding OAU working .
appreciate you help.

Hi,
I went through the long time consuming process in order to unlock my Hero from the Orange UK network. I ended up with a custom rom Default [ROM] Hero 2.1 UPDATE 1.4 [4/12/09]. However im finding this full of bugs. As im new to android i would like to get a stable ROM on there (like the standard Orange one) and was wondering if i put the origional one on there will the phone still be unlocked?
Alternativly if you can suggest any stable ROMS that would be great.

HTC HERO
HTC TOUCH HD
can anyone help with this info? would ideally like to sort this tonight
Reason no one replied is because your Q is not clear.
First how did you manage to change from Orange rom to generic, if I understood you, bypassing CID?
first of all this is in the wrong section of the forum, this belongs to q&a not development.
if we we are talking about simlock here it is my understanding that it is independant of the rom, and therefore not changed by a custom or stock rom. i have no experience with this, i'm happily using my hero with the provider selling it here so you might get a second opinion on that.
if you want a fast, stable, rooted custom rom get modaco 3.0.
+1 on MoDaCo's latest ROM - you don't want an original ROM as it will unroot your phone and make it difficult to root it again after it has been applied.
The unlocking only applies to allowing your phone accept SIMs from different providers - that is independent of your ROM. My Telus Hero is unlocked and working on the Rogers network.

Not quite true - the Orange version of 2.73 had a problem when entering unlock codes. Whether this was a bug or by design isn't known, but in order to circumvent it you have to flash a non-Orange ROM to actually unlock.
I would imagine that the phone would remain unlocked if you flashed back to the Orange ROM, as I think it was more of a code entry/saving issue, but I'd add another vote for a MoDaCo ROM.

hi,
I recently got my HD2-man what a wonderfull phone-the screen is definitaly the bizz.
I want to upgrade the standard rom "1.66.521.1 (76641)WWE" to the new 3.14 Rom; when entering my serial on the HTC support site for the update it gives an error. Will I brick the phone if I download the WWE ROM from XDA?
The service provider is VODACOM and I'm in South Africa, serial number is SH06PNW01693
thanks in advance
no it won't brick it, but it won't flash either cossounds like you have a provider locked phone.
you can either use hspl2 and forget about the 3.14 roms until your provider releases a rom, or make a goldcard.(dont say "how do i make a goldcard, it's well documented )
thanks for the clarification
Is there a specific reason why certain ROMS are available on certain "country" sites on htc support eg the WWE ROM is available in the UK location for download but not on the middle east and africa location. although it is the world wide english ROM? or am I missing something?
the phones have two locks, region and carrier. english is available on most regions roms, just not always. depends on the region and i guess also what the carrier specifies when they order their rom locked (rom locked short for carrier locked) roms.
short answer is i don't know why.
I currently have RUU_Leo_S_hTC_Asia_WWE_3.14.707.3_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship.exe but since I have a lot of problems with my Leo with that ROM (e.g. sometimes it won't charge at all until I soft-reset it, some notifications like for example PockeTwit are not working, WiFi doesn't work probably most of the times even when I'm just a few foot steps away from the access point I'm connecting to, the phone suddenly doesn't recognize the MicroSD card anymore after a Soft-Reset) I wonder if my phone's hardware is actually broken or if it might be just a problem with the ROM.
Based on my experiences with other HTC phones I previously had (Touch 2, Touch Diamond 2) I think that with HTC the operator branded ROMs are better optimized and tested when it comes to stability and performances than the generic unbranded (retail) ones.
So now I'm looking for an operator branded WWE ROM for my European 512Leo. I would go with the latest O2 ROM but unfortunately that is for the UK and so it has that stupid EU imposed volume capp and I really don't want that. Of course the T-Mobile US ROM won't work on my 512Leo so the only alternative I could think about is the Telstra Australia ROM but unfortunately that is pretty old
So does anybody know any other official branded Non-EU WWE stock ROMs I could try or is that Telstra one really the only one for my "special needs"
Thanks

I figured out that "RUU_Leo_1_5_TMOUS_3.14.531.1_Radio_Signed_15.42.50.11U_2.15.50.14_2_Ship.exe" works on my EU Leo perfectly (when flashed with Gold Card) - so no need to find a different ROM anymore
thx

Also, no need for goldcard, hspl will do that for you no problem.
I'm considering flashing the international firmware. I have three reasons for doing so:
Carrier bloatware
Carrier firmware update latency (not always the case but not wanting to take the risk)
Some users have confirmed that "international" improved the battery life & speed.
I have several questions before flashing:
My phone was carrier locked but I got the unlock code; will the code still work?
Will I get notified for updates for the international version instead of the current version (thinking the answer is "yes" but need to be sure)?
Do I need to take into consideration something in particular for flashing?
Other?
1) How to I determine if my Lenovo Yoga Tablet YT3-850L (LTE data only) has a REGION CODE?
2) How to I determine WHAT that code IS, if not evident in the answer to the above?
3) Is it possible to CHANGE a REGION CODE on an as-yet NOT ROOTED device? If so, how?
4) Might it be useful to change the REGION CODE?
5) Might changing the REGION CODE be a "Bad Idea?"
6) Is it likely that the SAME ROM will behave DIFFERENTLY on the SAME DEVICE if the REGION CODE is changed? (I know this can kill OTA updates on non-rooted devices)
CONTEXT: I have a Lenovo Yoga 3 Tablet YT3-850L. This is the SIM-equipped LTE data only version, no phone. My research indicates that this tablet was issued in THREE (3) versions: F (WiFi only), L (WiFi + LTE) & M (WiFi, LTE, Voice). However, there are only TWO ROMs for these THREE devices, and only TWO source codes: one for F and another one for L/M. Some have reported flashing the M ROM onto an F tablet, with the result being the appearance of a non-functional PHONE app. I am hoping that flashing the M ROM onto my L tablet would give me a functional phone in addition to the LTE data. There really is no separate L ROM. Reports elsewhere suggest that there are NO HARDWARE differences between the L/M devices.
So, I am guessing here, but think that the REGION CODE is the key to determining whether the (ostensibly) SAME HARDWARE functions as L or as M. Some countries (i.e., Russia, Czech Republic) offer M, but others offer L. I can't determine if BOTH L & M versions are marketed in the SAME country. I'm in the US, and my device is from a country which appears to offer only the L version. The marketing difference seems to be based on REGULATORY APPROVAL, best as I can tell. So, if Lenovo doesn't go to the considerable bother to get FCC or EU approval for the M device, it's just offered as an L.
I'm cautioned that flashing a ROM which is not in sync with the REGION CODE of the device is asking for trouble. Not sure that warning is a concern in my case; I DID change ROMs on my Samsung SM-T325 from one region to another w/o any issues, and AFAIK, the device thinks it's now a UK device. But it works anywhere. But, others say that having a ROM-Region Code mismatch can cause problems, including bricking the device.
So, can anyone tell me what I should consider( aside from reckless experimentation) with my YT3-850L regarding flashing the M ROM onto my L device in an effort to turn it into an M model? I can't find that my LTE-only L model even HAS a REGION CODE. That may be because it is hidden, or AFAIK, REGION CODES are only issued to PHONES, which the L model is NOT (though the M is). One thread suggested to be ready to SUPPLY the appropriate REGION CODE when flashing a ROM from another region. Here again, I don't know what to expect.
I'd appreciate any suggestions and especially specific guidance, links, etc. Theories may be useful, but experience with this obviously is preferred. Hope someone is interested AND knowledgeable in the area. Many thanks.

Code to changing modem region is ####682#
You need to go to CONTACTS, click SEARCH icon, when searching for contacts enter ####682#, there will be Your actual region at top of screen, below You can change region, system will reboot after, don't know what will happen with Your actual data, I made it after unbricking YT3-850L without any installed apps/data.
As for changing "L" to "M" I made it and my Yoga has been bricked (lost EFS, NVRam, IMEI, WIFI Mac, BT Mac, GPSID etc.), someone helped me unbricking this device, so if I were You i would BACKUP ALL DATA including .QCN file (NVram).
