[Gen9 Android Development] Speedmastersaxai:
Hi all,

Big Trouble in the House, cause i have Updated the OFW 3.280 to 3.2.79. Reading right, an Update/Downgrade and maybe crashed or wrong working CPU1. How it was possible, see below.

I have an Archos 101 G9 Trubo with OFW 3.2.80 installed. Which i´ve tooted the Custom Frimware 3.2.80.update from suru_petru. Rooting gets fast and without any Problems. Tabelt Performence seems to be nice.

So i installed "Fast Uninstaller" and removed (without making an backup) a few Google Apps, which was the reason for rooting my Tablet including the anroid.contact.sync.app. That was the mistake, where my Problems startet. After the app was deleted, my Tablet shows every ~2min an App-Error "couldn´t load...". Working or Gaming with the Tablet was impossible, a few things didn´t worked anymore.

I tried to Repair System, so i went in Boot Menu and selected Recovery System. Tablet was working, restarted itself and then i had an Boot-Loop. So i went back in Boot Menu, reformated device and installed OFW 3.2.80. Everything seemd working fine, so i rooted it again. After a while and installing a few apps, the performance problems began. Window-Animation was a little bit laggy, Fruit Ninja had from time to time Freeze´s for 2-6 seconds (Game Paused, after freeze was gone, the game goes on without any changes/performance probs.). The System Monitor shows 3 running Market app (normally there was only one running marked.apk) and a Bluetooth app.

Maybe the CFW makes some Trouble, so i decided to Re-Setup the Original Firmware from Archos. Again i´ve formated Device and installed OFW. If everything worked by Re-Setup OFW, the Tablet PC now should be a regular Archos Tablet (again). Window Animation Lags was gone, old interface was setted. But to be on safe side, I´ve just installed the Game "Fruit Ninja" and "System Tuner Pro" for System-/Freeze check. Then Startet loggin prozesses with System Tuner and played the Game. 3 Min while active playing, again an Freeze happend. As Freeze was gone, i stopped the Game and had a look on the Log (see 2. Post). Log-File shows, that while the Freeze is happen, the CPU1 Shuts Down and Reboot second device. It can be found a few times in the log. The System Tuner App has also an CPU Menu, to show CPU Speed and frequenze. CPU0 had 300Mhz and CPU1 was offline. For a few seconds the CPU1 sometimes was working/shown on Widget. If both CPU´s running, the widget displayed both with 1Ghz.

Even it seems to me, as if the CPU1 is the most time offline than online. So here must be the answer for my Problem (cause of the time when the next booted secondary Prozessor is recorded). Somethings wrong with the CPU. I´ve never made custom settings on Hardware (like overclock). So the problem must be the Kernel which i have uninstalled. After stopping loggin, i had a look what System Monitor is listed. And there was still the Bluetooth, with nearly (i´ve seen ther normally about 2-4 google apps. Now its about 6-9 perm) all google apps shown.

And how could it be, that the Bluetooth app is still listed? I´m pretty sure, the Bluetooh app was installed with the CFW. Cause i´ve never seen this app in System Monitor bevore. I never used/enabled Bluetooth since having the Tablet. So why the Bluetooth is still installed/active/running. It should be deleted with the CFW? - For me the only reason why the Bluetooth app is still active/shown/running/installed, it means that the Device or CFW wasn´t completely/correctly uninstalled.

Just for Fun i started the Tablet in Boot Menu. But now i come straight in the System Recovery Menu. The Developer Menu (No / Android / Developer Menu / Recovery System) isn´t shown anymore. Even in the Recovery System Menu there isn´t "Developer Edition Menu" anymore. In Recovery System - Developer Edition Menu i had removed the Developer Menu. In the Android Kernel Removing Menu the Info "Developer Menu will uninstalled and replaced with operator develop Menu. Load OFW from Archos for it" was shown.

This means to me, after removing Android Kernel, the original Kernel is needed. I´ve made what the Tablet wanted from me, but i think the Kernel wasn´t installed (correctly). Because the "Kernel Ino Menu" isn´t shown anymore in the Settings - About Tablet. If the Kernel is not installed correctly/completely, this can explain my Problems with CPU/bad Performance.

To delete any possibilitys of wrong/false installing Software and FW-Update should fix it. So i connected the running Tablet with PC and copyed OFW 3.2.80. The Tablet asked me if i want to make an Update what i´ve confirmed. But after restart the Problem with Freeze and slow running (as 2 apps would be runned on same time) still exist. Now my last hope was to install the OFW 3.2.79. So downloaded the OFW 3.2.79, connected running Tablet (which has FW 3.2.80) with PC and made an Update. After reboot System shows Version 3.2.79, downgrade via Update. But also didn´t solved my Problem..

Are my trains of thought and only explain why i´ve done the next step.

Status Information - Archos 101 G9 Turbo with 3.2.79 FW / Bootversion - unknown/5.05.000002 - C0x01

No Kernel Version in Settings shown and still having Performance Problems.

System Monitor Apps (Free Ram 176 MB / 210 MB if apps stopped / 30 sekonds after stopping 188 MB) = Google contact sync / Google service framework / Network-Position / 2x running Maps! / calender-storage / my Uploads / Google Mail / Email / Bluethooth (enable system?)

Nearly all Google Apps are listed in System Monitor, stop them is uselesse few second later all apps re-activated. I Guess thats one reason for slow performance. Sometimes its like i have muisc played and playing a game. Wifi isenabled - Airplain Mod on.

I´m worried about this much apps showed in System Monitor, which can´t stopped effectively. Especally the Bluetooth app is a mistery for me. I used the System Monitor very often, so i can say there was (till rooting Tablet) no Bluetooth and not so much google apps listed. The first time i´ve seen the Bluetooth app listed there, was after rooting CFW. So i think, some files from rooting/CFW still in Flash-Memory.

Questions:

1. Have a brand new Archos an Developer Menu shown in Boot Menu?

2. To Re-Setup an rooted Tablet, only format device? really? after all the Problems here i couldn´t believe it. And whats with SDE? All changes resetted only by a easy formating?

3. Kernel for Tablet really just the same OFW? In Menu just writed "AOS" File, so i has to be the OFW. Or maybe thats the Problem?

4. Is the "Kernel Version Info" necessary or a proof that the Kernel is correctly installed?

Thanks a lot
