I went trough an odyssey since I bough my Archos G90 Turbo some years ago.
If you have this device you may be familiar with this: constant application freezes and crashes, big keyboard lag, system reboots, can not wake up from sleep, fast battery drain, and a large etcetera of nuisances that make you sad and willing to crush this piece of ****.
After trying almost all the firmwares on the forum thread dedicated to this device I have come to a solution and I wanted to left it here so maybe it helps someone.
The problem with this device is the lack of ram, 512mb is very little and system comes full of bloatware and a lot of applications leave daemons running even when they are not running.
I have installed the stock rooted version of firmware 4.0.7 as some pointed out that is the one that runs better on 512mb devices, and then I have installed root uninstaller and started to remove all apps and services that I don't need.
For instance I have uninstalled:
clock, contacts, contact storage, DRM protected content storage, exchange services, gallery, Gmail, Google+, Google contacts sync, Google play store, Google search, Google tts engine , media center, media storage, media scrapper, talk, talk back, voice search, Japanese keyboard.
There are some system applications that can be replaced for others that use less memory and don't leave daemons like:
play store -> aptoide
gallery -> quickpic (solves problem of being unable to enter deep sleep)
media player -> mx player
browser -> opera mini
Gmail app -> email app
I have also avoided synchronizing anything, or installing applications I use sporadically.
I'm using the tablet since a couple of weeks after doing this and it finally works fine.
