Go back to stock firmware on a100 - Acer Iconia Tab A100

Hi,
I'm having problems with Exchange email after the last update. The stock email client only seems to sync older emails or none at all.
Is there anyway to roll back to the update or go back to the factory firmware without rooting? I did a factory reset and that erased all data but did not roll back the update.
Thanks

Factory Reset

I have the 2.2 leaked Rom and I am missing the Talk to text button on keyboard since the update. I was told somewhere else that a factory reset may fix this. If i do do a factory reset, will it reset my phone to 2.2 or to the version of when i got my phone?

[Q] Stock 4.0.4 yakju image flashed, home button no longer works

I don't know where to put this, search turned up nothing.
I took the Google factory yakju 4.0.4 image and flashed everything, except the radio which I replaced with UGLC1, then struggled for another hour to regain root. At end of the day data and apps are mostly restored, I have root again, but the soft home button now no longer do anything anywhere!
Anything to try before factory resetting the phone?
I'd factory reset... Did it work before you attempted rooting? Or hadn't worked since you flashed yakju?
I think the problem started after flashing. I was on yakju 4.0.2 before, flashed in mostly similar way, and I had no problems then.
Solved by yet another factory reset... Sigh
Solved by yet another factory reset... Sigh. At least it can receive calls again..
I kept the UGLC1 baseband.
I'm just flashing one yakju image after another while trying to keep my phone's data intact. How come each flash has become this tedious?

[Q] Running backup rom(4.0.4) and cannot send MMS

:cyclops:mE<<<Noob, I rooted the GS3 a while back and made a back up of the original stock rom (4.0.4) via CWM, the back up contained my old mobile number which brings me to my three part questions. I am running the back up rom with my old info, will this affect my multi media messages, I send them out but apparantly my contacts say they never received the messages. Text's are fine, and I'm able to receive the MMS and text's. Secondly the annoying prompt of SYSTEM UPDATE, keeps poping out, which I pressume wants to update to Jelly Bean and will take root away, right? Lastly before doing anythig is it recomended to run Chainfire's Triangle Away before flashing to the Official OTA rom (in case I have no alternatives? :highfive:Thank you, and again any advice is welcomed. :good:

This morning my Razr M received the latest OTA update. I was previously rooted with a locked bootloader (I know, bad choice).
I proceeded with the update but my phone massively screwed up: lost wireless, contacts malfunctioned, several apps failed.
I went through all the steps to clear cache, soft reset, hard reset, etc. Ever sense my phone has been stuck on the setup wizard screen stating "Please wait, this may take a few minutes". I left this morning at noon returned home at 7 and it is still on that screen.

Try using RSD to restore to the same version (4.4.2). I've gotten that wireless issue before, and I just had to format userdata and reinstall the update to get it working.
just roll back to orginal firmware by using RDS and after that,use OTA update
