I really don't want to do that yet but I will if there is enough demand. It would be better to wait until Paul has a chance to work on it and maybe get it working with the older hboot. I will post how to do it if I can get rollback to older stuff working, it's not a very nice solution for a variety of reasons.
[HTC Flyer, EVO View 4G] globatron:
Here's the first screenshots

Hey man!

What do you wan't? Must we worship you or only gratefulness, money, girls?

Hey man, when you have a leak and have the aloudness, then upload it, when you install it, then document what you done (or the reason why not), when you have screenshots, publish them, when you have a video, nobody will thankless for uploading.

But, please, don't fish only for attention every third post. Yes, to be honest, we will not love you or adore you, after you have done :eek:

So, be conventional and do it :D Please.

[HTC Flyer, EVO View 4G] Raioneru:
yeah I totally understand, i'm a bit of a n00b to this, hence my curiosity.

I didnt understand much about what was discussed here, I don't have S-Off, so fastboot didnt do much for me (well it showed me that I needed S-OFF)

hope you can do fix your problem :)
[HTC Flyer, EVO View 4G] globatron:
Nothing to do with any of what you said.

The reason for not posting the how is simple, it is not a nice solution and requires permanently voiding warranty.

I will work with Paul if he wants the help to make use of what I have to give people an option to install without doing that. I will post it if people really want me to, as you appear to, but it takes time to put together a proper post. If you don't like the answer then tough, I couldn't care less what you think.
[HTC Flyer, EVO View 4G] Raioneru:
we are all excited guys, lets be nice :)
[HTC Flyer, EVO View 4G] globatron:
Please, please, please, don't quote posts with pictures.

Guys, give me half an hour and I'll put together some details and post them, then I'll try a roll-back to the older hboot and a GB rom and depending on the results of that I'll post the how to get the GB with or without the possibility of rollback. There is a big health warning with this. For now at least you will be waiving the warranty.
[HTC Flyer, EVO View 4G] ovigt71:
1.mate, we lost the warranty at the day when we've decided to do s-off.....

2.doesn't matter what is the solution, let us know and then we're can decide if we do so or not....this is my point, no hard feelings... :) cheers mate!
[HTC Flyer, EVO View 4G] globatron:
1. Not true with revolutionary, it is reversible and HTC don't know about it, go back to stock and you're covered. This time you can't. Plain and simple.

2. Like anyone responsible I will not release information without understanding the consequences. I need to know what is and is not possible first.
[HTC Flyer, EVO View 4G] globatron:
Ok, a quick first impressions of running HC on the flyer.

The Good

It works

Pen interaction works everywhere for typing/buttons etc.

Much more compatibility in the market.

More widgets

Seems to be pretty smooth, no real lag.

The ROM is pre-rooted, it's a developer build.

The Bad

The buttons on the bezel are gone, with the exception of the pen action button.

The HC toolbar steals a lot more screen space than the GB notification bar.

Everything is landscape optimized. Some screens are clipped in portrait. Market is landscape only.

Phone support does not seem to work for now. Not tested much but cannot hear any incoming audio on the flyer.

Lots of FCs in various apps from the market (none from the ROM itself so far)

Other than that it's pretty much what you expect from HC and a Sense ROM.

I will add items to the lists here are I find them
[HTC Flyer, EVO View 4G] ovigt71:
1. yes- you're right!!! I already turned back to s-on following this

2. I totally agree with you ! thanks !!!

Hey,

So you can actually use the pen just like you can use your finger?

Have you tried sketchbook yet?

Or basically any other painting app?

I would also really appreciate information or screenshots about how the notes app has changed.

Do you see handwriting recognition?

How is the palm rejection working?

Thanks a lot for testing this out!
[HTC Flyer, EVO View 4G] nickiberli:
When i type "fastboot flash unlocktoken Unlock_code.bin" then I see that menu on the screen to unlock it. I can choose Yes or No.

If i switch to Yes and press the power button nothing happens. But if I choose No and press the power button, it reboots.

No Idea why..

Anyone an idea?
[HTC Flyer, EVO View 4G] globatron:
nickiberli, it should work there if you choose yes. That's all I did.
[HTC Flyer, EVO View 4G] nikoan89:
Just a question: after this procedure we will be able to flash custom roms or not?

I have no experience with the HTC Unlock so I don't know that.

P.S. How the hell did you mind to take advantage of the HTC unlock? You're crazy man! :D

After unlocking bootloader - can i runn ruu simply ? Or unlock and then run rru and then flash new Hboot ? will this do ?

Also help me how to run DD command??

So, I thought but you did so difficult that I become ironic (just a little bit ;-)

That was also clear for me because there is until now no way back... and I also expect that some will brick their Flyer.

To be honest, I didn't expect that your Flyer still runs HC. I will be not the first time here in XDA that someone assert everything. Still remember that also before any S-OFF some assert to have rooted their Flyer. Also no upload, no explanation and so forth.

And I am exuberantly happy that this time it is different. My excuses... :)

Hey guys recently htc has launched the htc evo 3d in india with a price tag of 35000(.....i.e. $710approx)...considering you guys have used this device for quite a few weeks so....would you recommend it with that price tag??...(also plz tell me the major annoyances you have experianced with this device)

Edit: its around $790-810...srry...took an older value for dollar.
[HTC EVO 3D] jgalan14:
First what phone are you coming from ?
[HTC EVO 3D] vari9:
I'm coming from motorola xt720.....I have a honeycomb tab as well....so I am pretty much familiar with android...(rooting and other mods as well)
[HTC EVO 3D] Neo3D:
I would go play with the SGS2 and the Evo 3D if you can. Both are great phones, so it's going to come down to Sense vs TouchWiz.

Also, HTC's bluetooth stack is BORKED and they still haven't fixed it yet. It won't phonebook sync to older cars with Bluetooth 2.x

For me, that's a deal breaker and I would get the SGS2 instead. But if you have a 2011 car, it probably has Bluetooth 3.x and you should be fine.
[HTC EVO 3D] vari9:
I pretty much like the sense over touchwiz.......and I don't connect my phone to my car so often......SGS2 also costs here like 30000....that's around $120 less than the evo 3d......sgs2 had launched here like 3 to 4 weeks ago so the price has come down a bit........

Can someone tell me which company samsung or htc has a better customer support and would always upgrade there models with the latest versions of the os (faster)....?..(I have seen/noticed sometimes that samsung is a bit slow in releasing updates)
[HTC EVO 3D] AfroCreame:
I wasn't happy with Sprints horrendous 3G speeds but now that I have a gsm version on att I love it! hah
[HTC EVO 3D] EricSS619:
I would never pay that much for any phone in the world
[HTC EVO 3D] vari9:
Hehe....the high end phones in india launch at this price range only......the iphone 4 launched at 35000 officially....which is like a month or two ago.....and was selling unofficially at 40000 since a year....(which it doesn't deserve at all...(.my opinion)) .....

$1 values around RS43-44
[HTC EVO 3D] Overstew:
I wouldn't only solely due to the speakers on the item. Otherwise, I'd say go for it.
[HTC EVO 3D] sprinttouch666:
I would only recommend this phone if you want the best phone ever made! :cool:
[HTC EVO 3D] Rage1ofakind:
Definitely recommend this beast of a phone! however that price is tooooooo high, wait for it to go down a bit and when it does GO FOR IT!
[HTC EVO 3D] pinky059:
Absolutely....I would play with both the SGS and the HTC. However, Samsung is terrible with updates. The Epic 4G here in the US on Sprint hasn't even got GB yet. It took forever for them to release Froyo.

On the other hand, HTC has very good track record of updates/support. I didn't get the 3D movie on the SD card that came with the phone in the US and *****ed to sprint and actually got a call from HTC and they took my address, had me on a conference call explaining what I did to determine I didn't have it, etc.

On the update side, I had the OG EVO and it was updated pretty regularly. I'd say probably 5-6 updates in a year, which is pretty damn good if you ask me.
[HTC EVO 3D] poweroutlet:
The Evo 3d is awesome but if the SGSII is $120 cheaper, I'd rather get that.

Phones there may be expensive there but at least the actual cell phone service is cheap.

The carriers here in the US love having their way with us customers, no lube either. :(
[HTC EVO 3D] sniperkill:
Samsungs customer service stinks! I recently came from the Epic, and we had to wait almost 8 months for froyo. Not to mention the code that Samsung used to get it operational was all hacked up. I would go for the HTC. You'll hate yourself for dealing with a Samsung piece of equiptment.

Hi everyone.

I'm very happy to let you know this good news.

and rooted with nvflash & cwm. :p

[LG Optimus 2x] smokeweedevery:
superoneclick maybe??
[LG Optimus 2x] orlroc:
Have u updated p990 with this rom???
[LG Optimus 2x] kitty's_daddy:
Okey.

You know su660 is base model of p990 (AKA Optimus2X in Korea)

There are little differences between those. (touch key, dmb)

and I guess sources of those are same.

Kernel version is same with froyo, but it is new build.

Wi-fi and 3G are faster. Launcher is softly.

Unfortunately or not, we can use froyo's OC/UV kernel.:rolleyes:

Oh, our forum(in Korea) have froyo's Oc/Uv kernel for su660.

and we are testing froyo OC kernel+stock GB rom. (Maybe, it is good.)

PS: Pardon for my poor English.
[LG Optimus 2x] aMpeX:
even though they are similar, you MUST NOT flash a SU660 ROM to a P990 device. If you're lucky, it will barely work, but more likely, it won't work at all. "Little differences" have huge impact when it comes to ROMs for devices.

Best example is the G2x, which is, apart from that pseudo 4G, the same devices as the p990, even more alike than the SU660. But a small change in the partition layout makes your device a NVFlash-restore-only case if you attempt to flash the G2x Firmware to an O2x.

So pretty pretty please, don't confuse people in these forums that flashing that SU660 ROM is safe, it is not, and if you can't wait for gingerbread, you should try Paul's Gr alpha instead.
[LG Optimus 2x] kitty's_daddy:
No.

flashing fastboot and cwm with nvflash and update su with cwm.

I found this at my korean forum.
[LG Optimus 2x] kitty's_daddy:
Oh, I'm so sorry. there are some misunderstanding. My device is su660.

and we (su660 user in korea) are using Cm7 nightly and miui rom for p990

with little modified kernel (cause touch key) and lib.

and the reason that I write this thread, I let you know GB for p990 is nearly.

Pardon for my poor english and don't misunderstand plz.
[LG Optimus 2x] ganaa:
My phone is Su660 too, but i don't understand korean so no rooting so far.
[LG Optimus 2x] kitty's_daddy:
I missed important one.

Official GB's system apps and framworks are changed *.apk+*.odex.

and play *.mkv with stock videoplayer stably. :o
[LG Optimus 2x] kitty's_daddy:
Where is your location? I know su660 is used only SKT in Korea.

Have you korean friend? I think you need korean's help.

This is very difficult to explane for me. This is our forum url.

http://cafe.naver.com/op2x/40132

It needs to register, maybe.

I'm so sorry can't help you.
[LG Optimus 2x] wapz:
Can you link or upload the rom somewhere? I think Paul can port the rom easily to the P990 except for the kernel for which he needs the source.
[LG Optimus 2x] FoliathR:
Hmm. I can't seem to access the forums properly... been trying for quite a while now...

Thanks a lot for the tip, I believe most devs here would love to have a copy of the Stock ROM, you can upload the file to file-sharing services like www.multiupload.com, www.mediafire.com, www.megaupload.com . All these would be fine for us =)

Google Translated Korean (I know it will be full of mistakes, but just trying to bridge the language barrier eh? =D):

알려 줘서 감사합니다, 여기에 대부분의 개발자들이 Stock ROM의 사본을 원하는 것입니다 믿습니다.

당신은 www.multiupload.com www.mediafire.com, www.megaupload.com에 파일을 업로드할 수 있습니다. 모든 이들은 좋다! 감사합니다!
[LG Optimus 2x] kitty's_daddy:
Your welcome.

I can give you only v20f_00.kdz now.

Do you know kdz tool ?

Use kdz tool and flash that kdz file to rom-up official GB for su660.

Our member built froyo OC kernel and gb ramdisk to boot.img.

And it operates and very good.

I guess Modaco's Paul can do port to p990.

Our forum appreciate to him and his awesome works.

Here is v20f_00.kdz and kdz tool

V20f_00kdz: http://www.megaupload.com/?d=KZY7BS94

kdz tool: http://www.megaupload.com/?d=MQWTLTLM

Caution! this rom is applied to only su660 (aka optimus2x in korea).

Do not flash to p990. It will be bricked.

This files are useful only for experts in xda and modaco.

Thanks to your concern. ;)
[LG Optimus 2x] FoliathR:
Thank you!

Sorry for more questions, but how's the GB update so far? Are the Froyo problems solved? Is it stable? I hope it doesn't disappoint like Froyo did...

...Now would somebody give Paul a ring? =D
[LG Optimus 2x] kitty's_daddy:
I think it is better than froyo.

It changed to odex then faster and stable.

Web browser speed is fast.

Stock videoplayer can play *.mkv stably (includes sound and res 1024x576).

and I'm backing up this rom with cwm for you. wait a minutes. ;)

Ironically, the issues are GPS and DMB in Korea. (Those are hardware's problems)
[LG Optimus 2x] zhehao:
Thanks for your heads up kitty's_daddy.

No worries, your english is decent. (;
[LG Optimus 2x] kitty's_daddy:

[LG Optimus 2x] kitty's_daddy:
Thanks your corcern.

I expect the good result. too.

Here is Official GB rom for su660 with cwm backing up.

http://www.megaupload.com/?d=LHKO50D0

I couldn't test this with P990. It will be bricked or not.

But i hope it will be solved this problems by experts in xda and modaco.

you can restore this with cwm .(I used Paul's moded cwm 4.0.0.5)

Included

1. Official GB rom for su660

2. Rebuilt boot.img (froyo's OC kernel and GB's ramdisk)

- I guess you should rebuild this with your kernel.

3. su.apk (rooted)

4. patched framework-res (activated CRT effect and 1% battery)

5. patched libsqlite.so

6. remove some system sound. (renamed sound file)

7. some SKT's apps.(service provider in Korea)

And you should modify APN list in setting/network.

Good luck.
