[XPERIA X1 ROM Development] Howshall:
Energy.XPERIA.21903.Sense2.5.Cookie.May.09 has SOD issues

I'm afraid to say that I've now still had the Standby of Death (SOD) issue appear while running Energy.XPERIA.21903.Sense2.5.Cookie.May.09 as well as previous Energy.XPERIA.21903.Sense2.5.Cookie.May.01.

Unfortunately despite the rest of the fabulous work that NRGZ28 has (and continues to do) on his Energy ROMs not knowing if my phone is in Standby or effectively dead to the world is not an option for me.

Looks like the combination of at least Build 21903 of WM6.5 + Sense 2.5 (+ likely HTC/WM standard Alarms) is not stable for everyday use.

I'm going to try flashing a number of different cook's ROMs to see if I can get a better updated picture of if any cook has cracked this problem or whether I'm still stuck back on WM6.1 to get a stable Sense 2.5 implementation.

Please note that all my flashes did make prior use of Task29, preferred flash from SD card, Hard Reset immediately after flash.

No major tweaks to ROMs during initial testing phase except Exchange Sync of Mail + Calendar, IMAP mail, ActiveSync of Contacts and PIMBackup of SMS and Call History + normally install of Opera 10 if not already installed.

No Reg edits or other CABs added. Just using standard features of cooked ROM.

See my Initial Flash post for more details on experience, testing and fixes/workarounds I found for all other issues.

If anyone else could comment on if they've had any SOD's with this exact Energy.XPERIA.21903.Sense2.5.Cookie.May.09 ROM or any ideas about how to avoid SOD I'd be very interested as it was otherwise a great ROM!

Standby of Death (SOD) Experiences on Energy.XPERIA.21903.Sense2.5.Cookie.May.09

11/05/2010 Approx 7.40am

- Phone had been on wall charger all night, although removed from charge about 6am and switched to silent when email or SMS alert woke me

- Phone went off correctly with 7.30am set alarm (Alarm set to sound even when on silent in normal WM settings tab)

- About 10-15mins after successfully dismissing that 7.30am alarm tried to bring phone out of standby via normal power button

- Phone was completely unresponsive, as if switched off, but would not respond to screen presses, no light up surrounds on any front or keyboard keys even though dark, no response to short or long holds on power button

- After 5 mins trying different things opened back cover and used Stylus reset hole to reboot phone

11/05/2010 Approx 10.30am

- Phone had been working fine since SOD earlier and had been used to check texts and new emails

- Put on desk not connected to anything

- Phone found to have gone unresponsive sometime between 9.30-10.30, should have sounded 15min snoozed 9.30am alarm at 9.45 but didn't

- As above phone completely unresponsive, yet if number phoned network waited giving ringing tone (although no response from X1) until pushed to Voicemail after normal interval

- Phone only restored to operation after Stylus based reset inside back cover

11/05/2010 Approx 6.30pm

- Phone had been working fine, was using it with headset to listen to podcast via Sense music tab, but had paused podcast when interrupted and phone had gone into Standby on own with set 2 min timeout (Not on power or USB, WiFi not enabled at time)

- Realised phone had gone dead when 6.30pm alarm I had set 20mins prior failed to go off by 6.32pm

- Tried to bring phone out of standby and phone was in unresponsive. No screen, LEDs, backlights etc

- Phoned my mobile number and heard it ringing but no response from phone (classic sign of SOD rather than lockup or crash)

- Only solution to restore phone was Stylus based reset or battery removal
