Guest Double-K Posted May 8, 2009 Report Share Posted May 8, 2009 (edited) Me and my gf both have a G1 on T-Mobile, her G1 received the 'Cupcake' 1.5 update OTA last week, since then her screen intermittently displays white lines and will not come back on until removing the battery for a few mins before powering it back up. My G1 still hadn't received the update OTA, so I downloaded it and installed via my sd card - I have had no problems. So I tried to run the update again on my gf's G1 via SD card but it errors, i tried the 'wipe data/factory reset' option too, but now when it boots it just goes to the update screen, rendering it useless. Does any1 know how to do a real factory reset, or roll-back from the OTA update? Kind Regards Double-K Edited May 8, 2009 by Double-K Link to comment Share on other sites More sharing options...

Guest Paul Posted May 8, 2009 Report Share Posted May 8, 2009 You say you tried a ALT-L/ALT-W factory reset? P Link to comment Share on other sites More sharing options...
Guest Double-K Posted May 8, 2009 Report Share Posted May 8, 2009 You say you tried a ALT-L/ALT-W factory reset? P Yeah it says that it is done, then tells me to reboot, and it just goes back to the 'triangle' screen. GF is not happy :-( Double-K Link to comment Share on other sites More sharing options...
Guest Double-K Posted May 8, 2009 Report Share Posted May 8, 2009 (edited) Right, I got some help on the T-Mobile forum (Click Here) in putting the old firmware back on (RC7 for UK) to aty least get the phone in working order, which worked fine. But - when trying to update it onto cupcake, as I did on my G1 (the problem device belongs to my gf, remember :-p) it errored; Installing from sdcard... Finding update package... Opening package... Verifying package... Installing update... E:Failure at line 1: assert file_contains("SYSTEM:build.prop", "ro.build,fingerprint=tmeu/kila_eu/dream/trout:1.1/TMI-RC9/128600:user/ota-rel-keys,release-keys") == "true" || file_contains("SYSTEM:build:prop", "ro.build.fingerprint=tmeu/kila_eu/dream/trouInstallation aborted. Press Home+Back to reboot Any ideas on this error? Also, do you know if T-mobile will push out the OTA update again, or do they mark the account as already having it? Thanks for your advice so far :-) Double-K Edited May 8, 2009 by Double-K Link to comment Share on other sites More sharing options...
Guest Double-K Posted May 8, 2009 Report Share Posted May 8, 2009 Thinking about it, the os it's running is exactly how it was when we got the handset, there was an update between then and the cupcake. Do the updates need to be done in order?, as i'd need to update to that version before updating to cupcake. Any idea what that update was?

Guest Double-K Posted May 9, 2009 Report Share Posted May 9, 2009 Well cupcake was pushed OTA to the handset approx 2 hours after putting RC7 back on, have had no further issues, so thanks for all your help. Double-K Link to comment Share on other sites More sharing options...
