(Root,Cwmr,Hacks) Pantech Vega S5 (SKY IM-A840S)

arvin2212 · Sep 9, 2012

Title borrowed from hackarchive to keep things consistent

I bought the pantech Vega Racer S2 (IM-A830L) and received it a few days ago. This was an upgrade from a Dell Streak phone that i was using for some time. This phone is amazing. The touch screen feels responsive, the screen is bright and nice, and most of all, I didn't experience any slowdowns / lags on this device. Everything was buttery smooth.

After 2 days of playing with it, and flashing it, I decided to sell it off, and tomorrow it will be delivered to its new owner. The reason is because, after getting used to a 5" screen device, it is a little hard to getting used to a 4.8" device.

This is where the SKY IM-A840S comes in. A 5" phone, that claims to have eliminated most of it's bezels surrounding the screen. A 13 Megapixel camera is included as well. The rest are more or less the same with the Vega Racer 2 (IM-A830L/K/S)

What do you guys think of this phone?

* There is a rumor that a Quad-Core version will be released, the SKY IM-A850, utilizing the Snapdragon Quad Core S4 Pro with Adreno 320 GPU. Not sure when it will be released though since I heard that the sales for the Vega S5 isn't that good at the moment.

I have also bought A840S, and it is very good.

Any idea how to remove the warning message about turning off the wifi when I move outside a wi-fi covered area?

Nice. Is there any lag? The phone responds properly? How about games?

Is the camera good?

I tried the A830L. The phone runs lag free but the camera, although 8MP, but performs poorly.

About the wifi warning, i think it has to be removed using a cooked ROM / editing system files.

Got mine last week. I am not really good at shooting camera, but from close range shooting is good. lag wise, I use apex launcher, so buttery smooth. Games wise should be OK as it using adreno225. I think it's still loose to my one x though

That is good to hear. It doesn't perform as good as your one x in games ? or basic tasks?

A new improved version of this phone is due to be released. Quad core with adreno 320. 5.3" IPS Screen. I wonder how its going to be like :laugh:

vagrante · Sep 16, 2012

Yeah, heard about the new a850 Which due next month. I dint actually use this for gamimg. This phone mainly for daily usage. But deep sleep is way better in one x, I think custom rom will really help. As most of the power go into cell standby.

Is there any 3rd party ROM IM-A840S ? Heard that it has so many problem with SMS in China/Hong Kong. Further, for some unknown reason, the 4G LTE 1800 is not working in Hong Kong.

vagrante · Sep 17, 2012

I had no pro with sms but just can't send more than 80 characters, due to Korea characters. My carrier do not have 4g/Lte so can't really test it.

Seems the phone has been rooted now? Link here: diendanso.vn/dien-thoai-han-quoc/1611-root-recovery-rom-cho-sky-a840s.html

Not that I can figure out how!

zazabichi · Sep 20, 2012

Hello,

Does it have a camera button? Microsim or ordinary Sim?
What about Screen quality?

No dedication buttons,but it can use voice to capture, like 'cheese or 'kimchi', using ordinary sim, and a 5" ips 1280 x 720

Just got one of these from HK. I think its already rooted with a custom rom already installed. Anyone know how to return to stock rom?

desmondtee88 · Sep 22, 2012

i dun see any difference ... for future proof wise .. better take branded phone like LG F160 ..is more cheaper yet phone accessories are easier to buy .. not SKY pantech phone.. Even the rom also not stable ... u have do more findinding about the roms on it ... price wise also expensive for me .... but if want to show of this is a good choice ...

I do believe you can use the Sky Self Upgrade Service to get back to stock, as with other Sky phones.
Before that, you'll probably need to download and install the USB drivers: http://file.isky.co.kr/upload/software/USB/IMA840S_USBDriver.zip.
Next, go to
http://dmfile.isky.co.kr/NewSelfUpgrade/index.html
You'll need to use Internet Explorer (ugh) 8 or 9, as the page will attempt to run an ActiveX control which does the actual flashing.
Once the drivers are installed and the page is open, you should see a whole load of stuff in Korean and a rectangular button with rounded corners and a spinning icon that is not yet clickable. Turn the phone off. Hold both volume keys and then power on. Select PDL Download. Then plug in the phone. After a while the icon should stop spinning and the button become clickable.
Flashing will take some time. And by some time I mean up to half an hour. You must make sure the battery is *fully* charged before flashing!

OT as well, I've ordered one of these to replace my A830S.
Hope battery life improves a little - this is the A830 (Vega Racer 2)'s weakest point, apart from the lackluster 4.8" TN panel.

Seems to be loads of info here. I wish I had paid more attention in school during my Chinese lessons: http://bbs.wpcnn.com/forum-192-1.html
