How To: Reliquify Honey

This may be old news for many, and a couple of quick web searches show plenty of good advice on this matter. Still, I thought it was very cool when I actually tried it out so I thought I’d write it up.

Liquid honey tends to crystallize after a period of time, often much less time than you will be able to consume all of it. The process for fixing this is quite simple:

Find a container that the honey jar will fit into
Put the honey jar in the container
Fill the container with boiling water
Wait
Repeat until you’ve got completely liquid honey

I tend to wait about 10 minutes before repeating the cycle. It usually takes 2 or 3 cycles for me to render the entire honey jar liquid again. If you stop before its done, it will much more quickly re-crystallize (days vs. weeks). Sometimes I turn my jar upside-down to get full coverage. Paper labels probably won’t make it past the first round of this (this explains why my jar is naked).

Android 2.1 on G1

Thanks to the hard work by the Android hacking community CyanogenMod 5.0.7-test1 is now available for the G1. My phone was already running CyanogenMod (CM 4.2.115.1) thus there wasn’t any need to root the device, but I did need to upgrade the SPL.

The CyanogenMod wiki has instructions that cover exactly what I wanted to accomplish: install DangerSPL and upgrade to the experimental CM 5.0.7-DS-test1. I’ll walk through the instructions I followed with some notes. With any type of firmware modification you’re clearly going to void any warranty you may have, and it is recommended to read through the whole procedure at least once before starting.

The prerequisites are: Rooted G1 (check) and a compatible radio (mine was 2.22.19.26I). You’ll need to download 3 files: DangerSPL, GoogleApps, and the new Firmware. Connect your phone via USB and place these files on the root of the SD Card.

You also need a recovery image. Mine is CyanogenMod 1.4 + JF, but Amon_ra is supposed to work as well. To verify you have a recovery image that is compatible, reboot your phone and hold down the home key – this will boot the recovery image.

To check that you are NOT already running the DangerSPL, enter fastboot mode. Reboot the phone while holding down the camera button. You’ll see something like:

DREA100 PVT 32B HBOOT-0.95.3000 CPLD-4 RADIO-2.22.19.26I

The DangerSPL will have HBOOT-1.33.2005. To exit fastboot mode, press call (green), menu, and power (red).

Allow me to stress – these instructions are all on the CyanogenMod wiki – reproduced here only to allow me to comment, all credit goes to the CyanogenMod crew.

1) Verify that you meet BOTH the prerequisites (G1/Dream & Radio)

If you don’t know if you’re phone is rooted, then it probably isn’t. Try google for some help. To check the radio version look at Menu->Settings->About phone->Baseband version, the radio version is the 2nd part of the version info. Or reboot into fastboot mode to check the radio version.

2) Copy DangerSpl (spl-signed.zip), CM 5.0.x, and gapps-ds-ERE36B (& Ebi1 port if required) to the root of your sdcard. Reboot into Recovery (CM Recovery or Amon_ra Recovery both work)

The Ebi1 port is for 32a phones. Again I’ll refer to the fastboot screen indicating we’re are a 32b phone.

3) To reboot into Recovery, restart your phone and hold down the ‘home’ key before the G1 splash appears.

4) Make a Nandroid Backup (ext not required)

Steps 3 and 4 are pretty self explanatory.

5) Flash DangerSpl (spl-signed.zip). It will install and then ask you to reboot to finish the installation, so reboot. It will then finish installing and reboot into recovery so you can flash your ROM.

This is the “scary part”. The DangerSPL originated as Haykuro SPL, this modified SPL takes away some of the /cache and allocates it to /system and /data – effectively allowing for lager ROMs. You shouldn’t have to do this step again, once you have the modified SPL you’re good to go for ROM changes later.

6) Flash CM 5.0.x THEN gapps-ds-ERE36B (& Ebi1 port if required); then reboot (Boot may take longer than normal) DO NOT reboot between flashing ROMs!

This is the actual installation of the CM 5.0.7-test1 firmware. The google apps portion is split off to avoid copyright issues for the CyanogenMod crew (in theory you should really be extracting the google apps from your existing device..)

That’s basically it. I was a bit surprised that all of my settings made it across to the other side.

For anyone upgrading, I’d suggest you also review the normal upgrade link. If you read that page you will find the comforting note:

Note: G1 users need to have DangerSPL, the instructions there will leave you with CM 5.0.x installed, no need to follow these instructions after (unless you nandroid restore).

You may also want to review the troubleshooting section of that same page.

I happened to have the Dalvik Debug Monitor (ddms) running to capture some screenshots. It turned out to be quite useful as the 1st boot cycle is very long.

Issues so far

I had a fair number of apps installed, and once I had the DangerSPL and the new firmware installed, I immediately starting getting low on space warnings. With only 6MB free, I was having trouble starting some applications (GTalk).

The solution was to enable apps2sd. The easiest way for me to do this was to unmount the SD card and use my Ubuntu desktop to repartition it with GParted. Since GParted allows for partition resizing, it was trivial to add a new ext4 partition on the end of the card.

Now you’re not done yet. Once you put the card back and rebooted, you want to modify the setting that tells the system where to put newly downloaded apps (on the SD card). Menu->Settings->Applications->Apps2SD. Now for each installed application we need to toggle it to the SD card as well if we want to clear out some of the internal memory. First head to: Menu->Settings->Applications->Manage applications, then select each application and use the Move button to change it’s storage location.

There are some rough edges. Some of the stock apps (Gallery) I had linked on my home screen. The gallery didn’t work, until I erased the short-cut and dragged a new copy out. Wow – the gallery is one of the most improved areas I’ve noticed so far.

You do need to fix your Sync settings. Go to: Menu->Settings->Accounts & sync settings, click on your account and adjust the sync settings. Most of them seemed to be disabled by default.

Initially I thought: wow – this is way faster. After a while I either got used to the improved performance, or it isn’t really that much faster. The 2.1 features are very nice to have. I’ve also moved from Twidroid to the official Twitter client which is only available on 2.1.

Bugs:

Text messaging is sort of busted.
Poor battery life (workaround and also fixed in test2)

There are other issues too, but it is pretty remarkable how usable this is for an experimental version. For more details go visit the forum.

Core i3 frugal upgrade

When I was a teenager and into my early 20’s my computer gear was always bleeding edge. If I had forgone most of the computer gear, I probably could have had a car during university – but having the coolest setup was what it was all about. Once I started work full-time, my work supplied hardware far outpaced what I could justify at home. Somewhere between then and my 30’s I lost the drive to have the coolest stuff and got by with trailing edge gear. Until recently my desktop was a refurbished Celeron 3.06GHz machine that I picked up a couple of years ago for $200.

The issue is that even a horribly dated machine can still run everything you need, just not very fast. Especially given that your average home computing is about surfing the web and maybe some simple file management (let’s ignore the gamer machine which is a totally different story). Having recently upgraded Jenn to a dual core iMac, and also getting a dual-core laptop for work – the celeron was feeling really slow. The straw that broke the camels back was the insanely poor performance of iTunes under VMWare hosting WindowsXP.

Trent had pointed me at techreport.com, specifically the system guide as a good source for reviews and advice. I had initially thought I’d get an AMD based system until the introduction of the lower cost Core i3 early this year. After some extensive online pricing/shopping I settled on a very frugal upgrade plan.

$129.77 Intel Core i3
$114.99 Gigabyte GA-H55M-USB3
$53.77 2GB DDR3 1333MHz (1 stick)
$54.99 Corsair CMPSU-400CX 400W Power Supply
$42.99 Cooler Master Elite 335 Black ATX Mid Tower Case

Total: 396.51 + 51.55 tax

Initially I had planned to re-use the current mid-tower case my celeron system was in, however the front panel plug connectors were not compatible and I didn’t want to start splicing wires to hack things to fit. (Leaving the case intact, gives me a completely functional but slower machine to pass on)

At the top of this post the picture is a close up of the i3 chip installed on the motherboard prior to the installation of the CPU heat sink/fan. If you haven’t built a system from the ground up previously, it may look complicated but its really quite simple. I chose to install the CPU/heat sink prior to installing the motherboard into the case.

Some of my friends teased me for only going with 2GB of RAM, but with my Ubuntu based desktop and my usage (even with VMWare hosting WindowsXP) I rarely use even half of my RAM. I do plan to upgrade to more in the future (6GB or more) but I’m waiting for the price of DDR3 to drop to a reasonable cost. The single 2GB stick was cheaper than some of the 2x1GB options and provides the most flexibility for later upgrades.

The power supply was a bit of a pleasant surprise. It came with cable ties, nylon sleeved cables, and a power cord. This power supply is also 80+ certified which was one of my requirements for a new power supply. The single large fan keeps the noise level to a minimum.

My motherboard selection was based primarily on the techreport.com recommendation. However, this is one of the few USB3.0 capable motherboards that offers integrated graphics support (when used with i3 or i5 processors). It has 4 slots of DDR3 memory (up to 16GB), Gigabit ethernet, PCI Express x16, IDE and SATA support as well as external SATA. This is a great foundation for my new system allowing plenty of future expandability. The only feature I noticed it was missing was SATA3.

Future upgrades will be to add a graphics card, a large SATA drive and of course more RAM. Looking further into the future, I may consider upgrading to an i7 when the prices drop. While this is still a budget system, it has legs and I’m back on the leading edge for a short while.
