Was until recently one happy owner of an Acer Liquid Gallant E350 [dual sim].
From 2/3 weeks, the operating system is collapsing. After startup, the mobile phone is terribly slow. Whenever I turn on the internet data, all applications [Android system] start to crash, and stays completely inoperable.
I tried to remove some applications (which could be compromising the system), but amazingly after I remove the apps and restart the smartphone, the applications are still there!
I've tried to through the "Settings >> factory reset without backup" and... nothing everything the same.
I've tried "POWER + VOL UP" >> "Wipe data / factory reset" + "wipe cache partition" and everything remains the same!
I've tried downloading the Stock Rom [OS_Acer_AV041.E350.1.000.22.WW.GEN1_A40I_A.zip] and through the Android system recovery, "Apply update from sdcard, appears an error" Signature verification failed "
Please, someone with a hint or could indicate how I can get this mobile phone to work properly or do a hard reset?
Hey, I have the same problem here as well. I did see that on a different website someone else complained about it too. Ive tried every form of reset, but nothing gets changed, even if I take out the SD and SIMcards.
Could you explain, or point me to an explanation of "even giving Format with sptools"?
Sorry, I am not an expert and just would like to reset the factory values to my phone. There is a facility for this and I have followed the procedures recommended... kind of annoying that the telephone just acts "as if nothing happened" (except that it is still sending me a buttload of errors about this or that application closing, often the same application closing over and over).
... In Forums in France (where i live) people are having the same problem ; it is only since October 2013 and there have been no responses from Acer about it.
I am about to say "so much for my 10 month experiiment with Acer phones... " and pass on the advice.
