Help
Anyway here is what I have found in level of severity.
UPDATE 6/3: A very short comment something I found about JTAG added at the bottom. For PDN but interesting. This is not the topic to discuss that, read the link and if you try it on your CRUZ Reader, post the results. If you cannot follow the thread on the link, PLEASE DO NOT post asking for help on this it is not something that is "explained" any better than that.
1.) Immediate Exclamation Andy
**SYMPTOM: You get to the update, and quickly go to the warning screen with an exclamation mark with Andy the Android.
**PROBLEM: Likely the ROM is bad or corrupt and nothing happened. This is usually a ZIP with the wrong name or wrong structure, or zipped inproperly. Did you make sure your SD card was not read only locked?
**SOLUTION: Unbend a paperclip and stick it in the reset hole to press the reset button and everything will be fine. Else goto #2
2.) Progress Bar for a while and then Exclamation Andy.
WARNING: NEVER RESET ON THE UPDATE SCREEN WITH THE PROGRESS BAR, WAIT TILL YOU SEE THE EXCLAMATIION MARK.
**SYMPTOM: You see progress bar goes for a while and then you get Exclamation Andy midway through the update.
**PROBLEM: Update process failed. There was some process, such as file permissions, that failed the update you have half an FW which is not good, but can usually be recovered.
**SOLUTION: Get a new good ROM in the SD and then do a "3 hand reset". Hold VolumeUp+Power and then have a second person insert the paperclip for you to reset (I suppose doable by yourself maybe but it certainly seem designed for someone with 3 hands). The important thing is to continue holding the buttons during reset to start an update from the new ROM as normal. Hopefully the new ROM should load otherwise you might have now have a "boot loop", or "white screen o' death"
3.) Boot Loop
** SYMPTOM: FW Update completes restarts but then boots to white screen, CRUZ logo, back to white screen, back to CRUZ logo, etc, etc, over and over.
** PROBLEM: Some bad pookie in the FW. Either your machine does not like a 800Mhz ROM (no one knows why) or "hacking" in the ROM you had did not take for various reasons, if you flashed several ROMs as some of them do only incremental changes and could have the system be placed into a bad state.
** SOLUTION: Same as #2 do a "3 hand reset" with a another good FW on the SD and hope it works. Also if you have ADB setup and you are able to get to your device you use the command "flash_image recovery /sdcard/recovery.img" or maybe "flash_image recovery /sdcard1/recovery.img" if you pull the recovery.img out (not sure of this) of the stock firmware and place directly in the SD. Otherwise goto #4.
4.) White Screen O' Death (WSOD)
** SYMPTOM: Your device has turned into a $100 flashlight. All you see is a white screen and nothing else happens.
** PROBLEM: VERY BAD pookie in the FW. Probably the same as #2 but worse symptoms.
** SOLUTION: From the consensus of the forum you are now in goat sacrificing territory maybe throw in a few virgins for good measure. Try ADB recovery above otherwise you basically you need to open the case unplug the battery and format the internal and external SD cards, then retry the firmware see post here. If that does not work, see post here. Note that I think the poster mixed up the URL and Text in his link for the ROM he used. Just cut and paste the URL in that post clicking did not work for me.
5.) Stuck on CRUZ Screen.
** Have not read a recovery on this or this might just be another description of the boot loop. If you just flashed wait a couple of minutes and just see if this is you FW update just needing to complete. Otherwise maybe try #4.
RECOVERY MODES SUMMARY:
A.) Reset - Just unbend a paper clip and push the into the reset hole to reset the device back to power on stage.
B.) SD Update - Hold Volume-up then press Power to power on launch and use an FW update ROM from the SD Card
C.) "3 Hand Reset" or Update Reset.- Hold Volume-up + Power and continue holding and press reset to reboot a device and go into update mode. Used when cannot be manually powered down (boot loop or white screen)
D.) Let out the Factory Air - Open the case unpluging the battery and reformatting the SD cards have been indicated as something that has help recovery.
E.) JTAG - Link here. *Might* be possible but this is for PDN (Reader should be very similiar) and requires a much higher level of techincal knowledge and even need make your own breakout board. You should not post here about this, try some of this info FIRST. If you get somewhere with the Reader then make your own topic about what you discovered, and post a solution if you find it. Don't ask someone how to do it, if you cant follow it here then no one is going to be able to explain it to you. Not saying this is even possible or that it is the same from the Reader. Serial access has been discovered in the Pandigital and this is noted to be same as the Cruz Reader. You should also note the memory offsets are likely different than this post as PDN is a 512 NAND and Cruz is a 256.
Thought it would be good to have these all together. If anyone else knows of others I will update. Hope it helps...
