I think, Rokot might have been the last orbital system, which began with intentional suborbital flights

Even before this news about the valve becomes public, the associated press put out a very harsh story on the angara launch attempt:"MOSCOW – The first launch of Russia's new space rocket after two decades of development has been aborted moments before its blastoff as President Vladimir Putin was watching via live feed.Friday's botched attempt to launch the Angara booster rocket was the latest mishap to dog Russia's troubled space industries, whose Soviet-era glory has faded in a series of launch failures.Angara is built to replace the Soyuz, a workhorse of the Soviet and then Russian space program, designed more than four decades ago.........."This is their story for a 24 hour delay. Imagine if SpaceX, ULA, or orbital got that coverage? I could only imagine what it will be for a return to factory delay. I suspect that the AP author wouldn't know the difference.

On June 30, Russian authorities again issued a warning to pilots to avoid areas around the Kura impact range on the Kamchatka Peninsula, indicating that another launch attempt was scheduled for July 1 and July 2, 2014. Given the short time available for repairs, it could indicate that only basic checks would be done on the rocket and its flight control system could be just reprogrammed to ignore the problem with the valve
start "Angara" under the most optimistic scenario, will be held in two weeks.
They are still planning a July launch:http://www.kommersant.ru/doc/2502800Quotestart "Angara" under the most optimistic scenario, will be held in two weeks.
So what caused the scrub? The answer is, ahem, rather "SpaceX-ish"...... http://www.russianspaceweb.com/angara1pp.html#energomash
The following inspection of the rocket confirmed that the oxidizer tank drainage valve had remained in open position and led to the loss of pressure, which had been detected by the flight control system shortly before liftoff. It was not immediately clear what caused the valve to stuck, but all oxidizer systems operate in the environment of the cryogenically cooled liquid oxygen and prone to freezing as a result.[/size]

What's the default state of an unpowered drain valve? Open or closed?Or was it, as is implied by the last sentence, a result of the cold temperature - perhaps some ice-formation due to unexpected humidity, or some nucleating impurity that was a mechanical impediment to the valve closure...?
First half-decent on-pad shot I've found, probably fuelling before the first attempt. Almost approaches being hi-res
Next attempt is tentatively set to July 9th: http://lenta.ru/news/2014/07/05/angara/State commission meeting will be on July 5th which would review the readiness and confirm the launch date.
