Help reverting to pre-3.2 - Acer Iconia A500

Hello everyone, my first post here.
I do realise that there is info around for reverting from 3.2 OTA.
However, none of the tutorials and related messages in each thread has helped me downgrade my 3.2 being a new member, i am also restricted from posting in the development thread
So can someone please help me, and please moderate this thread if it is in the wrong place etc etc. Im desperate T_T
So, following this tutorial to downgrade:
http://forum.xda-developers.com/showthread.php?t=1276227
Using method 1:
I keep getting that no Iconia Tab is detected :S
I had run this as an admin, rebooted my pc, tried it on my sister's pc (both running win 7), installing official acer usb drivers to no avail.
Using method 2:
The update starts and the loading bar appears. The downgrade appears to run, probably up to 10%???, then the android with a yellow exclamation comes up T_T
I have tried a factory reset, but neither method 1 nor 2 will work.
My Tab is still working so I am still very grateful. Can anyone with ideas on how to get this downgrade working please advise. All help will be greatly appreciated.
EDIT: Moderator please delete this thread. I have managed to fix the issue:
Factory reset, then i dl'd the package from method 2 again, and ran again. now working flawlessly =]
Sorry to have been a nuisance

Need a little help restoring/Flashing my streak

Hey guys,
Im not new to flashing roms etc,
but this is the first time i have so much trouble with it.
I read the streak how to PDF and followed the instructions on installing superboot.
when i installed superboot, the phone reset itself, and when it turns on, the dell logo shows up and the "home and menu" led starts flashing on and off and the restarts again.
I tried following the instuctions on how to restore the phone, but none of it worked. i specifically followed this guide: http://forum.xda-developers.com/showthread.php?t=805112
and when i try to flash the update.pkg, i get an error at the end about the boot bin or something like that.
anyone have any ideas?
Thanks!
I heard something about a QDL tool i could use...not sure what that is and i couldnt find an exact answer searching the forums.
any help would be greatly appreciated!
EDIT: found a guide on using the QDL tool, im going to try it now wish me luck lol
If u got yours from best buy u need to use QDL. Read carefully and just do as it says
thanks for the tip, it is indeed the best buy exclusive white one....running qdl as we speak
ok everything is good now!
i just need to figure out why when i try to install dj steves rom it gives me
"failed to verify signature"
ok so now i am having a hard time rooting the phone.
I am using the android 2.2 provided from QDL and am trying to root via universal androot which isnt working for me.
any other ways i can root?
note: im using a best buy dell streak
If you are updating to his 1.6 then you dont need to root it.
It it pre-rooted
thanks, I figured it out.
It turns out that the "how to pdf" (while an amazing guide) linked me to outdated versions of the the recovery which is why it would not work.
everything is working now,
running steves 1.6 and loving life. Thanks every one for your help!!!!!

Moving to General
ok so I try to load a Update.pkg file and i get the following error message.
FOTA model name mismatched
what is the FOTA?

Touchwiz Update bricked my non-rooted Tab (static lines across screen)!

I decided to go ahead with the TW firmware upgrade. Everything seemed to be going fine until I tried to install it and it told me there was an error and I needed to hook it up to Kies first. I had already been using Kies with it on my Macbook for a couple weeks now so I went ahead and plugged it in. Kies recognized it as usual and all the information came up.
So I went on and tried to install again and it said it needed to reboot.
It reboots and comes to the Samsung Galaxy Tab 10.1 screen like normal (right before it starts the galaxy animation). Next thing I know it comes to a screen that looks like the attached images! I immediately unplugged it from Kies and shut it down. Every time I start it back up it does the same thing. I honestly have NO idea what to do. I can't even return it as it's past the 14 day period and I (stupidly) didn't buy Staples' bogus $160 insurance.
I was not rooted before. This was a stock tab that I bought at staples. It had the firmware 4.24 when I bought it, I think.
Please, any help is appreciated. I tried doing firmware recovery in Kies but the pop up comes up in Korean and I have no idea what it says...
Edit: More info. I'm not the only one with this problem. Two other people have posted on AndroidPolice about this. http://www.androidpolice.com/2011/08/04/samsung-galaxy-tab-10-1-wifi-touchwiz-ux-update-is-now-live/
The software is definitely running underneath all that mess but it's literally impossible to see what is going or to touch anything.
I guess this thread is about the same issue

Thanks, I'm checking the thread out now. I probably should have searched more than just Google before posting but I freaked out when it happened.
No need to freak out . we have xda and dev to solve all our problems
i have exactly the same problem as you... what should i do now?
I get the same screen but after rebooting! pfft it's making me really sad :\
I'm sorry but I tried reading this http://forum.xda-developers.com/showthread.php?t=1171089 and couldnt understanding what should I do!
What CWM + my device is not rooted, all I could understand is that the thread contains instructions on how to root your device..
I just want my normal screen back!
Please tell me what to do in simple english :\
And now I did a wipe and the stripes are gone, but the screen is black instead :\ still not working. Please help me!
Are you sure you didnt sit on it?

So I need to follow all the steps for rooting except the last one which is the actual rooting? Great thanx! Do I need to use Kies? My current computer is Mac but I guess I need to download those things to a Windows machine to make it work, right?
Thank you very much
I had the same problem. I upgraded the update on my non-rooted tablet and got the funked up video mess. Per instructions from Samsung support, I hard booted to the recovery menu (power+vol down, then power up, down on download screen) and did the factory wipe. After that I ended up with the black screen. I could tell things were working in the back but couldnt see a thing. I figured I would throw it on the Kies and it saw that there was a factory upgrade so I let the Kies run through it and it works fine now.
Dont know if this will help w/other but it worked for me.

Bricked Tablet

Hey,
I recently became the owner of a bricked Iconia a500 tablet. Beyond that, I don't know much about it and I cannot contact the previous owner...
The situation:
It will boot the the Acer logo, but it doesn't go beyond that.
I've searched this forum (and others) for ways to bring it back to life. A factory reset doesn't seem to do anything at all.
I can boot into recovery mode to load a rom, but cannot find the proper rom. CWM does not seem to be installed. I've looked for stock roms but none seem to work.
When I try and load a rom I will inevitably get a white triangle with an orange exclamation mark inside of it. Next to this is the android man.
I've found a few threads that purpose links to a stock rom, but a lot of them have file shares linked to Megaupload... which is.. well non-existent now.
Again, I can not tell you the anything about the current software.... if you know how I can find out that alone would be a huge help! = )
Many thanks,
Robert
This might be your best luck..
This flashed thru your computer adb.. apx mode..

Hey Erica,
Thanks for you very speedy response!
Well, I read a lot of that thread... lol probably more than I should admit. I followed the procedure but was unable to get a good connection via USB.
I was finally able to get it to register a Factory Reset thanks to that post. Had tried it a few times before... must have not been pressing hard enough?
Either way, it is stuck on Erasing Userdata... and Erasing Cache...
I saw that it was suggested it could be a hardware issue... What is your opinion?
Thanks,
Robert
I still think its a rom issue..
You might could try to download the rom again. and try again.. there is also another thread in the DEV section that does the same thing but differently you could try that or maybe posting there where a TRUE Developer might be able to help you..
I just repeat what i have learned from my own mistakes and read from others..
Sorry im not more help ..
Trust me Erica, you have been a great help! If I find a solution, I will update this thread with it = )
Thanks!
Robert

[Q] Noob help Rooting please

On so my first post and I have watched noob video and it scared the crap outta me for my first post but my apologizes first. So sorry if this is the wrong section and I did research the topic first but it hasn't helped in me finding a solution so here goes ...
Question please, if you can help me. I followed your intruction as per the Wugfresh rooting tool 1.5.4, now when I got to the step to click the root button I also checked the box with the custom recovery and then hit root. My table then gets stuck in the screen with the android guy lying down with his compartment open on his stomach, (like I said I'm a noob) lock state is unlocked. A message appears on my PC screen that states "Waiting for your device to finish booting back up ..."
I tried unplugging the tablet and tried pluggin back in and hitting root again without the recovery and nothing seems to happen even the screen remains the same after I unplug the device.
I have since tried and researched on the forum and seen others with the problem and a new version that Wugfresh has put out a 1.5.1 referencing this issue but unfortunately I cannot find the download for this software anywhere. I followed the link that seemed most viable to download the software but seems that is just takes me back to the original post with the 1.5.4 download ....
Help please and again sorry for wasting anyones time if this is a wrong thread spot or if this has been covered.
Android 4.1.2 and build number is JZ054K

You are better off posting in the toolkit section: http://forum.xda-developers.com/showthread.php?t=1766475
Wugfresh is online. I'm sure he can help you learn to use his tool better.
