Help Unbricking PE - Page 3

mr_ed · 06-16-2011, 05:43 PM

Actually ... I think build.prop is the problem. There's a section in the update.sh script (inside update.golden.zip):

if [ "$UPDATE_DEVICE" != "$TARGET_DEVICE" ];

where $UPDATE_DEVICE is read from the build.prop that's in update.golden.zip and $TARGET_DEVICE is read from the build.prop already on the PE.

If the two don't match, the script ends the update process and reboots. If I understand correctly. (I really don't know scripting.) If the script has trouble reading the PE's build.prop - like if it's garbled or not there - then it won't get a matchable device name.

It looks sorta like to me that that matching attempt could be switched off (commented out) in a case like this. I'm thinking it's there primarily to keep from putting big-Edge on little-Edge and vice versa ... a safety switch that could be overriden in an emergency.

I dunno. Anybody else?

Oh -- another post in the meantime. Interesting! Try opening up update.golden.zip and taking the build.prop out of there.

I think I got what you mean. When changing for the market fix I did change the build.prop
ro.build.fingerprint=esi/edgejr/edgejr/:0.9/ERMINE/1353:user/release-keys as per somebody instructions. editing this now an see if I can rewrite the firmware. thanks. I will report on results.

Still the update.zip on usb with menu /rotate on boot does not work unfortunately. should i comment out if [ "$UPDATE_DEVICE" != "$TARGET_DEVICE" ]; from the script? is the update.zip not crc verified or something?

vicinc · 06-16-2011, 07:46 PM

I did edited out update.sh in golden update renamed but still does not boot into downgrade mode

mr_ed · 06-16-2011, 07:57 PM

Hmmm, well....

By the way, although I said to use the file from update.golden.zip, that's the wrong one if you're trying to preserve ermine.

The problem shouldn't be in the update files - I've used both, to from dingo to ermine and back again - I'd expect the problem to be something that got hosed on your device the the update is looking for, and I don't think build.prop is the only place you can derail the script. It just seemed like the most logical.

Like I said before, I don't know what I'm doing ... but I'll think on it some more.

Vicinc -- just want to say congratulations on getting partway back! Very interesting reading what you and the others are discovering/uncovering! I hope you'll all stick with it.

Good luck!!

An idea from another forum - take out the internal memory card and re-do it from a known good one.

it would be great to have a virgin PE titanium backup I can restore, easier than disamble the unit? I also do not have another PE internal card <edit> image, it would be great to have one. if we could persuade one of the clever guys to go into an edge we could have a custom rom and one with recovery enable will enable us to experiment even more without fear of borking the device.
I did tried with both build.prop from ermine and golden, I was trying to get back to dingo to a clean virgin system but no luck so far.

mr_ed · 06-17-2011, 07:38 AM

Well, and the internal "card" may not be a consumer-type card, either. It might be a soldered-in chip.

I couldn't get Titanium to run on dingo 1.13, which is what the update.golden.zip took my PE to. Root Explorer too. They both complained about not having root even though z4root had run, and when I ran it again it said the PE was already rooted. And "enable ADB" wanted a password, but not the one I'd found on the net.

So ... at this point > I < can't supply you with a Titanium'ed dingo. But I'll try ADB from the PC side with the psneuter you got and see what I can destroy.

Mr Ed, can you get an Ermine virgin PE titanium?I could restore this and if works I can than use the update to Dingo. I can not understand how a simple build.prop edit could ruin the restore procedure. those Entourage people created they own tech issues but not having an easy recovery. little bit too late for me.

vicinc · 06-17-2011, 10:14 AM

I think my permission or certain files are corrupted. when I deinstalled and app and reinstalled started working. so a copy of the edge ermine and entourage apps may help me.

kennyminot · 06-17-2011, 11:44 AM

I've debated installing ClockwordMod, but I'm afraid of destroying my system. We know that Entourage used some kind of custom update.zip file, so they might not have a traditional restore partition.

vicinc · 06-17-2011, 11:47 AM

kenny can you use titanium backup to backup everything on a virgin ermine please. I may get mine working with a restore.

vicinc · 06-17-2011, 11:48 AM

I think robot got as far as one could without a SDK. does anybody know how to pm him?
