XiaoMi powerbank/Mi3 sales postponed to tomorrow

Reinstall the Samsung USB driver or try another USB port.

This is what I use,

I have given up on Kies already after having it on my machine for a year. Pretty much useless as backup is limited.

Your issue to me does seem like just USB drivers problem if everything else is working fine with your phone (i.e. download mode, recovery mode and phone operates normally)

Same like me, waited SO LONG until checkout page can finally load (@12:11PM), then after key in shipping details, powerbank already out of stock

The solution is to flash ICS stock ROM (which gives you old bootloader and can overwrite newer JB bootloader as well). Then use Mobile ODIN to flash your new 4.1 or 4.3 JB ROM - Mobile ODIN will never overwrite bootloader.

NOTE: If PC ODIN cannot be used to flash your ICS ROM, then have to check if Kies can do a wipe phone for you to install the ICS stock ROM... don't think Kiees supports downgrade normally.

Yah, some people just fly by question and then cabut

Mine yes coz Boeffla kernel supports it. And why coz I may need to carry large files on my S3 to copy to my Notebook as backup for work as well as the random odd movie for travel.

Am using Anker 7200 mAh now, love the battery life and don't mind the bulk. The only thing is the much weaker phone coverage signal. Where I stay, I can get 4 or 5 bars. Now I get either 0/1/2 bars only
But in major/main town centers, of coz no problem with signal.

I had a problem with a weird RILD bug where the RILD process under the Phone app is a huge battery drain (only got 2.5 days from my Anker). Only recently found the solution was to shut down the phone for 5 or 10 minutes. (Both hard and soft reboot will not work to fix this problem.)

So will share later once I drain my battery today/tomorrow as the stats are not accurate now. But I recall it lasted me about 4 days with more than 10 hours of on screen time... to hit 10%. Anker battery instructions says to best full charge once hits 10%

Yes, if the mobile signal is not particularly strong in your area; once you use a large extended battery for S3, the mobile signal is definitely impacted (however, if it is already very 'strong' 5 bars, it may still be 5 bars after you install the battery). If you look at Amazon reviews, you can see people have returned the Anker and Zerolemon for exactly this reason. It really depends on your telco and coverage area.

If root,
1. can run trim anytime (newer kernels will auto trim) - trim required on eMMC when storage has been in heavy use (deletes/writes), see example of trim app (http://forum.xda-developers.com/showthread.php?t=2104326). It can cause performance slow down.
2. can greenify apps with auto hibernation, see https://play.google.com/store/apps/details?...isfeng.greenify

OR just do a full wipe and reflash
OR factory reset.

Main causes of slowdown for me are having many apps installed and many apps running at startup, hibernate them or make sure they don't start at boot (Xposed boot manager module can help with that as well). Installing/deinstalls often will need trim on demand to help with performance.

Yupe, similar.
http://pocketnow.com/2013/08/06/android-trim-support

In my experience, after installation/deinstallation of large apps or after doing delete app cache/thumbnail cache, there is a bit of noticeable slowdown, so I just run the trim filesystem from Boeffla kernel config (I used to use the trim app when I was on Perseus). I like to control my own phone

All the newer 4.3.x and higher JB stock kernel will auto trim on a schedule.

Yes, for Nexus, definitely fstrim (which is the trim command) runs in the background and triggered automatically (within 24hrs?)... Not sure 100% about Samsung but I would assume so as well since it is Android 4.3 framework (kernel?) feature.
http://www.anandtech.com/show/7185/android...l-nexus-devices.

Stock S3 JB 4.3 kernel supports fstrim command. You just need root to run it.

Yes, have heard many cases OTA soft brick the phone

1. Try with a different cable (or cable that is guaranteed working)
2. Check if can go recovery mode, if can, wipe cache partition and reboot

OR redo the ROM flash directly
1. Download the Stock ROM
2. Go to download mode
3. Use PC ODIN to flash the ROM

If NOT working, likely you have to do a wipe (lose all data)
1. Go recovery mode, wipe data/factory reset and reboot
2. If not working, then redo ROM flash

Exactly my views! Let me be more specific
Marketing - huge spends to compete with Apple
Firmware - very slow to release, initial releases buggy and often causes OTA problems, bootloader locks/downgrade issues, bootloader and Knox warranty rejections, no Exynos source code
R&D - Exynos still not as good as generally as Qualcomm Snapdragon, on the low end side only recently decided to use MediaTek in upcoming phones
Innovation - Time to get a team that can really innovate beyond S3 (S4 & S5 is really meh)

If can afford it and want to avoid problems, go get a original Samsung Battery from official SEP (Samsung Elite Partners); more expensive but guarantee to be genuine. That lelong posting 99% cannot trust, even chance of 1% real, it is probably taken from a genuine set who knows how long ago and resold in this way. (The buyer of that genuine set probably got a fake battery instead).

Plenty of complaints about Sun Global battery quality (and it is only slightly cheaper than original Samsung) and I am sure you have heard of many horror stories of exploding 3rd party batteries...

That is a good find. If they're willing to provide 6 months of warranty - have more peace of mind and likely to be original.
