Hey ppl. I am from India so can I flash this? I checked on google but found no official ICS update. Is the one posted by Football the official one?

Yes the most recent one posted by football is an official RUU.
I tried flashing the official one by renaming it to pg32img.zip but it says installation aborted. I did it through rom manager though. Any suggestions

Of course you guys CAN NOT! Even if you're supercid you CAN NOT!
First you need to install this RUU: RUU_VIVO_SENSE30_S_HTCCN_CHS_3.09.1400.7_Radio_20.4802.30.0822U_3822.10.08.28_M_release_237362_signed
Second you can run this RUU, and only then:
OTA-VIVO-ICS-35-S-HTCCN-CHS-4.08.1400.2-3.09.1400.7-release-264230rsi8pgoc0lc0k4xe.zip
Third and only at last you can run this RUU:
OTA_VIVO_ICS_35_S_HTCCN_CHS_4.08.1400.3-4.08.1400.2_release_264573gxkspn0rakg03dic.zip
ONLY then and only then you got the latest full stock and official HTC ICS ROM for now. And yes, maybe you need supercid to install the first RUU, cause it's meant for Chinese devices with Chinese cidnums.
I am using an incredible s on Virgin Mobile Canada. I am being told that this device is not being updated to Android 4.0. Instead, HTC told me to go to htcdev[dot]com/devcenter/downloads to download the operating system. I have a couple questions;
1. What region do I use; TW, WWE, AU, TUR, SPA, HK CHT, CN CHS, etc. ?
2. What description number; 4.08.1400.5, 4.14.980.2, 4.10.708.1, etc. ?
And most importantly,
3. How do I do install the new operating system on my phone?
Would be a great help! Thanks! :cyclops:

Thanks, But on the HTCDev site there is only a CRC. Is this the same? Will it update to ICS? If not, can I use an RUU for another device instead?
and is it possible to do on a mac via the htcdev website?
and does the phone need to be rooted?

Virgin Mobile gave you bad information. At the HTCDEV.com site, you will only find the kernel source code for the devices. HTC no longer has a public download site where you can download the actual RUU (ROM Update Utility).
You need to go to the Development section and look at the "Shipped ROMs" sticky thread. There you will find a link to a site that has several RUU's for the IncS. You probably want to get the ICS WWE 4.10.405.1 RUU.
Upgrade, deregionalise without GoldCard?
QUOTING FROM THE DEVELOPMENT THREAD (I'm not allowed to post there):
Default HTC releases 3 ICS RUU on HTCDEV.com
HTC has posted 3 Incredible S ICS RUUs on [htcdev]
All 3 are labeled 4.14.405.2 and when I examined the N.American/Canadian version here is what I found:
1. android-info.txt lists all IncS modelids and has wildcards for most CID. This means that this RUU is generic and probably could be used on any IncS WITHOUT the need for a goldcard.
2. HBOOT version is now 2.03.
3. A newer radio is included.
ENDQUOTE.
Thanks for this, I've been reading the forums for two days now trying to figure out what the best way to upgrade my Incredible S is. This looks like it might be it, but I would like to make sure -- any advice is appreciated.
I am using an Incredible S from Virgin Mobile Canada. It is running the stock Android 2.3.3 OTA update from August 2011. I left Canada and paid to have Virgin SIM unlock the phone. Since then I have never seen another operating system update notification, I assume because I am now decoupled from Virgin's update server or some such.
The phone is S-ON and that's fine, I do not need anything fancy or custom, at least for now. I would just like my phone to receive stock HTC Incredible S upgrades -- I know there is one for 2.3.5 which I hear is quite good.
I spent last night making a GoldCard -- but now, as your post makes clear, it looks like there is a stock Android 4 RUU that will upgrade my phone and de-regionalise it. Does this sound right? I have downloaded the RUU you linked (they list 3, but I think it's all the same file, which is encouraging since I want it de-regionalised), and I'll hunt down a Windows machine to run it if indeed this is what I want.
Two further questions:
How best to backup the phone? I've seen apps like Titanium but it looks like the phone needs to be rooted. Is it really possible to revert back to 2.3.3 afterwards? From what I'm seeing it looks as though downgrading can be as hard as upgrading.
Do we know if this release of Android 4 is really better than 2.3.5? If it's still buggy, perhaps using the GoldCard and 2.3.5 would be worth it.
Thanks very much.
I understood that your phone is s-on, but do you still have warranty to force you to stay, or you want to try to s-off? I'm asking you this cause if you s-off your device you'll have a wide range of possibilities for roms without need to make a gold card or use RUUs, even with Revolutionary hboot. Also, returning back to s-on from Revolutionary s-off is not hard at all.

The posts above yours were made before HTC posted official ICS RUU's on htcdev.com
[edit] Just noticed all the ICS RUU links on htcdev point to the same file, so there's a good chance you'll be fine.

All ICS RUUs on htcdev are the same, so it's one RUU made for all versions of IncS.

Thanks for the replies.
Regarding S-OFF, I will certainly think about that in the future; for now I'm happy with just sticking to the official HTC upgrades and see how I like it.
I agree that this new ICS RUU from htcdev looks like it will work straight out of the box, as it were. Only my two final questions remain:
1. How best to backup the phone?
2. Is ICS going to run slowly/buggily on my Incredible S (now an older phone)? I suppose the only way to be sure is to try it...
Thanks again.

There have been complaints of ICS running slowly on IncS, that is with the official release, however many custom roms are lightning fast..

This is the file I used to upgrade my incs to ICS: http://dl4.htc.com/RomCode/Source_and_Binaries/One_Generic_code_Vivo.zip
I'm on Bell Canada, the above file is a generic Canadian ROM. You'll be missing the Virgin bloatware, but if you need it, you can get it from the Google Play Store.
How are you finding it runs, noticeably better or worse than Gingerbread?
Thanks.

Hi everyone,
I have a HTC Salsa after some issues with logging into google market place I decided to reflash with the following stock Salsa ROM found on XDA:
RUU_Icon_G_HTC_Europe_1.12.401.1_R_Radio_47.14.35.3030H_7.47.35.17_release_193257_signed.exe
The reflash was successful, but my handset shows software version:
1.12.401.1_R
It used to be:
1.12.401.10
Kernel version is also different.
Does anyone have the stock RUU for software version 1.12.401.10?
...or can anyone suggest how to get the system.img file from an existing handset which does have version 1.12.401.10?
Knd Rgds,
yyo
Good luck. Never play with a systeem iimg. What is your area or country.
There will be no way of getting your exact system back. Its damn near impossible. Closest you will get is by flashing a stock rom. But by the sound of it you have a stock unit.
I'm interested in wwhy u would reinstall the ruu to fix a google play error though. But silly lol, nether the less u did it.
If u tell me your country I maybe able to point u in thee right direction more. But as said. U won't get your original stock back again. And your kernel is bound to be different its newer. Ever thought the ruu u tried is newer than what u had?

Hmm..., doesn't sound good.
Unless version 1.12.401.1_R is newer than version 1.12.401.10 the RUU found here at XDA is older than the version shipping with the handset. HTC is guilty of a lot of things but versioning software in reverse is not one I've some across yet!
My handset was purchased in Nov '12 in the UK and I used the Europe Stock RUU to flash, it was the only one with a version code similar to mine.
Any ideas?

regardless of which network your with...the salsa in the uk is primarily O2
version code just means its the shipped version. the newer the code the better the version. you will notice alot of changes in this ruu including the kernel code but do not worry. it is normal.

Thanks for the assistance, I bought the handset sim-free (off network) so it was true HTC stock - no additional network provider rubbish.
I'm downloading now and wil give the O2 ROM a bash later on.
I also have an unmolested HTC Salsa running the stock rom 1.12.401.10, is there any way to extract it?
KRgds, yyo
No, u maybe able to when u unlock the bootloader and install reecovery, but swapping img files from roms is dangerous and not recommended.
Although its sim free, all salsas in the uk are predominantly O2. It will work, it'll just have so new options there. My suggestion is get it working and test everything. Wifi data Bluetooth etc.

Not a lot. U will get these updates in all stock based roms. U can turn of the update Notifier in settings.
It will probably allow u to download it but it won't install. It wwill just freeze out.

Thanks BigBearEvo all working now, tested the hardware and all looks ok, a number of 'extras' there but I can live with that.
I would note that although the version number is greater, the 02 RUU is dated June 2012 whereas my previous HTC RUU was dated Oct 2012.
Looks like my previous HTC RUU was newer, probably HTC's last update to the Europe RUU before they dropped support for the handset.
Cheers for your help, yyo

Hello,
I just bought an HTC One in Germany (Vodadone) to use in Brazil and it is working just fine. But since it is a Vodafone version it takes longer to get Android updates releases. I was wondering if it is possible to flash the Developer Edition image, which is carrier free, on my phone and stay true to the original HTC build.
I know that there is the dev build available for download on htcdev.com. Has anyone tested it? Is there any tutorial here on how to do that?
Thanks in advance.

Hey guys,
I've decided to buy a M7. Because my money doesnt last, i've to buy a used one
Well, I like custom Roms and want to install one on this device.
But before I buy one, I have still a few questions:
Are there any special versions of the m7 which dont can be unlocked / crom installed?
Can I install a crom only with a by htcdev unlocked boatloader? What I can with s-off, i can't with s-on unlocked boatloader?
Do i get a higher hboot Version with a higher Rom Version? So if I install 4.4.2 OTA i get the newest hboot?
Are there any differences between the hboot versions? Does a Rom runs better with a newer hboot or something like this?
How is the battery drain?

Can't really answer all the questions but I'll answer what I can:
1. Depends where your m7 was from. Tmobile/Verizon/Sprint had some differences. It affected the way I had to root my phone. Flashing roms should be universal depending on the package you use.
2. Not sure what that means with the grammar bit. You need bootloader unlocked to flash a new rom. Most of them come S-on unless you bought an OEM which may have come S-off. You can flash roms with the phone S-on.
3. Higher bootloader versions seems to come from more later models of the HTC One from what it seems.
4. Bootloader versions seem to affect the difficulty level of being able to turn something from S-on to S-off more than anything for the average joe.
5. Battery drain depends on what you do with the phone and how much brightness/volume etc you were having. I play games on my phone now and I need to charge my phone (from about 10-25%) to about 70-85% about 2-3x a day. I play pretty often (rotating between brave frontier and puzzles and dragons and the like). I also don't charge 0-100% to conserve my battery's life. Also, it will depend on how well the previous owner has treated the phone's battery before it arrives in your hands. If they 0-100% it before many times, you can be sure the battery life is not going to be what was advertised.
Take my ansewrs with a grain of salt because I'm not a dev, but I just lurk and tried to learn to tinker with my phone. Hope it helps.

1) Dual sim variant
2) If u unlock the bootloader, you can flash a custom recovery and root. Even if S-ON, you can flash Cyanogenmod and all Sense roms. S-OFF is needed for GPE based ROMs
3) Only if you're on a stock unrooted One with a locked bootloader, OTA's will update HBOOT. But, if you're on a custom ROM, you'll need to manually flash the updated firmware, which updates HBOOT.
No, there's not really a difference between HBOOTs. Update them if you wish to. No compulsion
4) Battery drain is lesser on custom kernels than on stock
Okay thanks for your answers.
I read a bit more and I read that its only possible to change the cid with s-off. And the cid is important for RUUs. And for some brandings there arent any RUUs right? So its usefull to get s-off if I have a ****ty branding, otherwise its not usefull for me I think.
I've read there are problems with T-mobile brandings, what are their specials?
And because of the battery, I need for one day around 3h display on at medium brightness. I think I will use the arhd Rom. Is this possible ?

Tmobile is GSM. So, its nowhere as problematic as Verizon or Sprint. Plus, Tmobile hasnt recieved 4.4.3, so its on HBOOT 1.56 or lower. So, there's really no S-OFF problem.
I think you'll easily get upto 4.5 hours on stock kernel. Otherwise, custom kernels are also there which have better optimisation
Great thanks. And whats about the purple camera Problem ?Does it appear on many devices? Are newer devices fixed and havent this problem? And do I have still my guaranty for HW problems (like the purple cam) with a by htcdev unlocked device?

When there's moderate/low light, the camera is unable to pick up that original colour. It gives off a horrible looking purple tint. It appeared on quite a few devices, including mine.
HTC definitely wont fix it if its bootloader unlocked unless you have a developer edition. I RUU'ed the phone before giving mine fr repair. Service was excellent; within 3 days, they gave it perfectly repaired.
Im not sure if all newer models are fixed; if you're lucky, itll be alright
Well, that makes me contemplative..
Is the stock Rom very bad Or its useable?
Especially the battery drain interest me compared to a crom.
Because if I havent any guaranty after flashing a crom and there are such Hardware problems.. I dont know if this is worth.

You always have the option of returning to stock. I had a custom ROM on my phone when i noticed the issue. I RUU'ed the phone back to perfect factory settings. You will also be able to do the same. You can regain manufacturer support if you have hardware issues
No, the stock ROM is pretty good. I used it for 2 months before i rooted. The built in power savers work very well; there isnt a considerable difference between stock and custom ROM
I wouldn't say stock ROMs are bad for battery life. I still think custom ROM + custom kernel (ie elemental or bulletproof) gives much better life
