[Eee Pad Transformer Q&A, Help & Troubleshooting] archdem0n:
First, Lonnnng time reader/modder/hacker/technut, first time poster.

Secondly, my questions are: 1) Anyone else had such a positive experience as I did? And 2) Anyone else reproduce or trigger this ‘update’ in ICS?

Story below:

So I just purchased TF101 used, brought it home, and found out the long and hard way about the SOD/RR/DOCK/BATTERY/KERNEL issues that are plaguing a lot of users. So I researched for the past week (I'm a new owner), tried JB, ICS, etc, rom after rom. Still had same issues, and new ones (no wifi, sound, docking support gone, etc).

So, I went BACK to honeycomb 3.01 by flashing official update (WW version as I am in Canada) zip via CWM. I wiped cache, dalvik, data via CWM. Installed the zip. Tablet booted up perfectly. I did not sign into the google store. Turned tablet off completely WITHOUT being docked. Cold booted. Shut down. Used it for about 1.5 hrs, no reboots and could not repeat SOD/RR. However, HC is very slow compared to ICS. I then looked for the 3.2.1 update as it apparently makes the dock work correctly, and could never find it ANYWHERE (one rapidshare link and it was dead), all links were dead as the JP vers is the only one on Asus official site. 'check for updates' within the tablet did not work.

Next, I downloaded official xx.27 ICS off Asus website (around 253mB). Same procedure. wiped all cache/data/etc, flashed in CWM still (never put stock recovery as many recommended, didn't see the point). Booted tablet. Signed onto wifi, skipped signing in google account. Once in, turned off and cold booted back on. Used it for maybe 10 secs, and Asus updater pops up in task bar. The update had the same file-name of the update I just flashed however it had a July 27 date on it, and it was 302 mB (noticably larger than the 250~mB) update. NEVER saw this dialog before, even with my many attempts previously and all the different flashes/roms. Updater rebooted, installed itself (maybe 2 mins). I shut down completely once back in. Also, I still have not signed into my google account.

Following ICS update and shutdown, I then plugged my dock into wall outlet. I then finally docked (while off and for first time during entire process) the tablet, which then booted up. It immediately recognized the tablet, and made that ping sound confirming it was connected. Tablet booted up. I shut down, cold booted one last time. I then put it away on my shelf, lid closed. I opened this morning and 0 SOD or battery drain, which happened with EVERY SINGLE kernel/rom I tried for the past week. It would either SOD or RR. I left it open on 'about tablet' with uptime counter. It is still going. I checked various emails this morning, and ran some videos, etc, etc. Trying to reproduce RR/SOD. Usually it would occur within 10-15 mins of actually using it unit/being on wifi/etc/sleeping and waking.

I have a feeling that somehow Google is sending code (since you authorize OTA updates when you sign in) via being signed in that is somehow RR/SOD'ing (my theory), or there is some mysterious update I somehow triggered through this process. If anyone has reproduced this please let me know. But for now, this seems to fix battery drain at the very least, however I am running stock CPU clocks.
