The Weekly Q&A: Week 46

In this regular XDA feature, the news writer team scours the forums to find five questions and answers which may be of use to you, or may simply provide an interesting read.

Q‘I don’t understand what is different between Clockworkmod Recovery 150MB, 250MB and 400MB? If I flash a 400MB recovery can I install a ROM that requires 150MB? If I flash a 150MB can I install a ROM that requires 400MB recovery? ‘

AThe size speaks for itself. Some ROMs (like Sense ROMs) have lots of components, which requires more space from your internal memory (NAND). And others don’t, like MIUI and CM). If you flashed a 400MB Recovery you MAY be able to use a 150MB ROM on it but it’s absolutely not recommended as the ROM may malfunction and when you try to use a 150MB recovery with a 400MB ROM it will not install or get stuck in a boot loop.
You can check the modded size by checking flash.cfg (open with Notepad).

  • Q&A originally posted in the HTC HD2 Q&A forum thread.

Q‘I want to unlock my Nexus S’s bootloader and root the phone using a Mac running OS X 10.7.

I downloaded the SDK, installed it, put the phone in debugging mode, turned it off, booted into the bootloader, then opened terminal and typed fastboot devices — nothing shows up, cannot find, doesn’t exist.

This is what I get — -bash: fastboot: command not found

I’m not here to waste time, I’m sure it’s a simple thing I’m missing.’

A On Windows or Linux, you would use “fastboot devices”‘.

On OS X, you use “fastboot-mac devices”.

  • Q&A originally posted in the Android Software and Hacking General forum thread.

Q‘Is there a way with Android to transfer calls?

Example:
Phone 1 calls Phone 2
Phone 2 transfers to Phone 3
Phone 2 drops from call, leaving Phones 1 & 3 connected.’

A You’re thinking of call conference. Yes it’s possible. Just follow the steps in this article [external link]. When you’ve done that and want to end the call so the two others can talk, just hang up.

  • Q&A originally posted in the General Q&A forum thread.

Q‘I received an email containing a WMV file. I tried to open it using my Nexus S 4G and get the error message that it is not supported. My father has an EVO 4G and he can open the exact same email and get the WMV to play fine. What am I missing here? We tested this on numerous emails. I have Rockplayer and many other players on the phone and none of them seem to work. Anyone else having this issue?

A The Evo may have a video driver that the Nexus does not. You could try arcMedia – it plays everything I throw at it.

  • Q&A originally posted in the Nexus S Q&A forum thread.

Q‘I’m new to the Nexus One. I can’t find a overclock kernel over 1.1GHz. Is there one out there?

A All the custom kernels allow overclock.
Almost no Nexus will work when overclocked above ~1150MHz.

ben_duder is an editor on XDA-Developers, the largest community for Android users. Hi! My name's Ben, and I'm proud to be one of the news writers at xda-developers. I live near London and have spent the last ten years wasting all the money I get my hands on on new gadgets with which to fulfil my technolust. I first got into HTC phones when I found a Lobster 700TV (the HTC Monet) at a very good price, and I'm ashamed to say that I couldn't have cared less about what operating system the phone was running as long as I could watch The Simpsons on the bus. As fellow Monet owners might know, the 'TV' part of the phone's alternate title was somewhat deceiving and was completely abandoned by the service providers in England. However, by then I had already fallen in love with the freedom Windows Mobile had given me. After the Monet came a Universal, with a Touch Pro following that. I've just bought a G1 (yeah, I know, get with the times!) because I'm really interested in Android as a budding operating system and don't think I could ever cope with a 'dumbphone' now that I know what's on offer. Although I haven't contributed much to the site in terms of programming or cooking help, I hope that I can give a bit back by letting you guys know what's new through my articles. If you have any questions, suggestions or complaints about those articles, feel free to get in touch with me via PM using the URL above.

Samsung Galaxy S6 Edge Drop Test

The Samsung Galaxy S6 and Galaxy S6 Edge are already proving to be amongst the head turners of 2015. From favoring their inhouse Exynos 7 SoC over the Snapdragon 810 SoC (which ended up causing issues to its main rival); to ditching the removable battery and micro sd card slot in favor of a more "premium" device, the flagship duo have a lot going on for them at this stage. Regarding the premium redesign which replaced plastic with metal and glass,...
