[Help] Lots of freezes and crushes after updating to 4.0.5

Hi,
I've had my Archos G9 80 updated to the latest android official 4.0.5 from and since then i'm expriencing lots of crushes and freezes. I'm getting them randomly with no specific app working.
Also, i have tried to do full formats (Android + Data), and still having same issues.
Does anyone have any idea what else i can try?
Thanks.

I had lots of freezes too (not only with the latest firmware). They seem to be gone since I changed the CPU govenor from "hotplug" to "interactive". I'm not sure yet that it was the reason, but try it and let us know if it helps.

Yes, can this be done from the phone itself? Within the ROM?

You can set this in any tool that is intended for overclocking. I don't overclock, I only changed the Govenor.
I use "SetCPU". ("No-frills CPU Control" should do the same.)

So does this have any other effects on the phone?

Nothing too serious. Your CPU is clocked dynamically so it doesn't run full speed when there is nothing to compute(save energy). To my understanding the govenor is basically a policy to manage how quickly the frequency steps up/down on changing CPU load. So "powersave" is supposed to save energy but make the system a little less reactive than "interactive" Governor for example. I think I read somewhere "hotplug" deactivates the second core on low load situations, I suspect for some strange reason my device might have crashed sometimes on trying to wake up the sleeping second core. Well maybe I'm wrong, that's why I'm interested if it helps others.
I didn't notice any change in battery lifetime, mostly it's the display anyway that drains the battery. Everything is running well, battery lifetime is great too and no crash/freeze at all since i changed that setting and it crashed almost every damn day before, no matter if it was Honeycomb or ICS.

I downgraded the device to 4.0.4 and since then, no crushes.. I guess for some reason 4.0.5 isn't stable on my device.. ill stick with this version unroll they get another one out..
To downgrade, just install official update file of the version you want to upgrade to..

changing govenor from "hotplug" to "interactive" seems to help against random freezes. 4 days without problems until now i had freezes with ics, but never with honeycomb.

That seems to be my problem too. Setcpu requires root. is there a very easy way to do this, just to run this setcpu? There used to be a z4 tool, but can't seem to find it anymore.
Edit I see that I need superoneclick. Will temporary root suffice or will I need permanent root to change the governor setting.and keep it so.

Unfortunately all know temp root variants tend to brake things- im Honeycomb sound, in ICS 3d driver.
The only real option is to enable SDE and use custom firmware.
As for freezes- try reinstalling apps. Direct upgrade from Honeycomb does not work for all

No, it won't. Gen9 system layout is different than for most other devices

hey, back to topic
5 days without freeze with govenor "interactive". i witched back to "hot plug" this morning and had to reboot my tablet 2 times today. for my case, "interactice" seems to help against random freezes.

mines performance intstead of interactive... experienced some freezing n interactive..

Man I'm really pissed.
Yesterday I had to hard reboot 7 times

hmm,
sounds not good. archos stands not for high quality i guess. we get what we pay . i had an archos 101g8, now a 101g9 and trouble with hard-/firmwares since 2010. i think, this was the last one - no furthermore advantures
@IrishStuff09: you did reformat for ics or upgrade from honeycomb? the best way is to start from scratch and skip upgrades.

[Q] Does anyone else's A100 slow down

Does any one else's a100 become super laggy after a few minutes of being on.. I am running the latest flex reaper I even overclock it all the way but I get this huge lag after the first few minutes of being on.. anyone else experience this or have a fix for this?

I do not experience this issue. When you flashed the rom, did you do a clean install? Have you formatting the device?

Yup.. I format everything.. I use the touch recovery and just use every option that it provides and wipe everything.. It even does it when there is nothing installed. I usually delete almost all the useless system apps that I don't use like the google music app and all of the ones civato provides... I even change the animation settings to .5 in the developer section.. should I turn them off all together?

The animations should not have anything to do with it. Does this only occur on that rom? Have you tried other roms and experienced that issue?

not many other roms out there.. I have used stock and his.. had the same issue on both.. Also happens on my brother's a500.. it usually happens when unlocking and going into any app.. it sits there for a few seconds and then opens whatever it is i opened

This is starting to sound like a hardware issue. Before that is concluded, you could:
- Make sure the governor is not set to "conservative"
- Try a clean install of CM9
If the problem still arises, its most likely a hardware issue.

I'm using the OC kernel and have it to 1500.. I also always leave it on performance.. I figure it would kill my battery life but I don't use it much.. and i tried cm9 also.. too many issues as of right now

It doesn't seem it can be anything else but a hardware issue in that case.
NB. Overclocking to a high frequency can cause instability and bring about that issue (but since you experienced it on the stock rom, its quite likely not to be that).

the overclocking helps to speed it up a tad bit.. for the most part it just lags.. i did a clean install just now

Thought I would jump in. Stock ics would slow down and lag on me, jittery transitions poor performance in games or movies, but it took an hour not a few minutes. However testing the T20 kernel before the release kernel had that exact issue, bogging and lagging within minutes.
His release kernel doesnt do it, and flex extreme as well as my cm9 builds don't, even with T20 kernel. Consider flashing that kernel to see what happens.
Side note...what issues did you have with cm9? And what release? My build 1 has been running for 3 days no reboots stable as can be undervolted and OC when needed. Something to maybe think to try to see if it persists. T20 kernel works fine with it too.

That reminds me...setting a screen off profile with the same min/Max speed can cause issues with that, give Max a notch or two higher. And don't have it change the governor leave it the same. So like interactive screen on Myst nit be conservative screen off, doesn't work that way.

I had the same issue on stock. I noticed there are 2 weather applications installed (version 1 and version 2) immediately after I disabled the old weather application (version 1) this stopped happening. I used the ICS GUI to do the disable.
This might not be the case in custom rom, but is true for stock. Post reply and let me know if this fixed it for you also.

Do you have a micro SD card plugged in? Try reformatting the card with a computer. Worked for me.

I felt the need to add my two cents in this....this has been happening to me for the longest with the flex reaper rom ONLY. I've used stock and ZN's rom and those did not lag after unlock...only flex reaper. I'm currently using flex reaper and still experience it from time to time but doesn't destroy my day at all...

Give the CM9 nightly ROM's a go. No Bluetooth n no HDMI audio, but everything else is fine n damn smooth. Those issues will be fixed though

I installed Flex 100 Reaper with stock and it it seemed to run smooth enough. Then I installed the OC kernal, and started to get lag. I was looking around to find the OC settings, but can't see it anywhere in settings..
Can anyone direct me to where can I adjust the governor/max/min CPU settings?
Sorry for the noob question.

To over clock or vice versa, you need to have a custom kernel that allows it. A custom ROM is also good, but not always needed, but it is suggested Some apps on the market have over clocking abilities but an over clocking kernel is needed that is compatible. Also those apps have a kernel, but is specific to some devices. But go to your device's forums and find a kernel that has over clocking abilities then flash it. Some apps just allow you to over clock to the SET speeds of the kernel being used. Also for battery life, I suggest you use betterbattery stats on the market.

SO which config would be the best ?
hey Thanks for your help bro !
considering i am already in the forums for my device , can someone recommend the best kernel and the best rom to install ?
And how do i go about installing it ?
PLease keep in mind it should be able to support maximum over clocking and underclocking .
Thanks !

Underclocking is doable with just root access, which can be obtained by using ZergRush. This will only work on firmware 4.0.2.A.0.58 or lower.
For overclocking, I would recommend DooMKerneL which requires an unlocked bootloader. It supports frequencies of 134MHz to 2GHz, though I think the stock kernel can go down to 122MHz or 128MHz or something (DooM changed the frequency table in his kernel).
To test the stability of your phone after overclocking, you can run stress tests with StabilityTest. Underclocking will not change the stability of the phone, it'll just make it slower.
My favorite ROM is Gin2JB, although anything stock-gingerbread-based should work just as well.
For testing performance, I recommend AnTuTu

Thanks again
Thanks for your help !
Now one question , does doomkernel have inbuilt over clocking and under clocking ?
also as you said it resitricts the underclocking to 134 Mhz but the stock goes to 122 Mhz . isnt thier a way to make this one also go the lowest possible value?
and what about the Adreno 205 @ 245 MHz GPU that the play has .. can we overclock underclock that somehow ?
Thanks again

Yes overclocking capability is built into DooMKerneL, and of course underclocking. You'd have to talk to DooM about putting in lower frequencies if you want anything lower than 134MHz in his kernel. He tried overclocking the GPU at one point, but it oddly gave worse performance in a blind-test so he removed it.

While we're one the subject of over clocking, you NEED an app like SetCPU to overclock right? Just wanna make sure DooMkernel isn't already set to 2.ghz. Yeah probably a noob question...

Yes, you need an overclocking app. I think it defaults to Min:249Mhz Max:1017MHz. The Min might be lower, dunno. The Max definitely is 1017MHz (1GHZ) until you specifically tell it to overclock though

I would like it if theres a kernel that ALSO allows to underclock and overclock teh GPU AND CPU .
Otherwise i take it , Doom is the best to go forward with right ?

[Q] Core and frequency control according to temperature

My N2 makes me crazy when it gets warm.
When it reaches about 36 celsius degrees it starts with frequency limit of 800MHz.
The second step is making 2 cores offline and at last my gadget becomes limited to 2 cores at a max. of 500MHz.
It becomes almost unusable for me when in car. I use two navis in multiwindow (Waze and Sygic) and AutoGuard recording in background with FullHD and in about 5 minutes it's restricted hardly.
I know it's for safety reasons but I think it's too strict.
Is there a possibility to raise the thresholds of these by a few degrees?
What kernels support this?
There is a nice app called Android Tuner which is able to set these tresholds but it is for Qualcomm CPU-s only...
Thanks for any answers in advance!

Not exactly understand...
There must be a safe setting for it as with Perseus kernel the thresholds are higher, but not too much. I forgot to edit my question according my experiences with Perseus.
At least with Perseus I get a max of 1000MHz at most cases but it is not enough for me cause I use apps needing high resources.
Would You be so kind to write about the value to be changed in order to get higher thresholds?

If I understand you correctly. Then you could try trickster mod.
Or try saber kernel. I use this baked into the Jedi rom.

Thank You for the advice!
Now I had some time so I'm on Saber kernel and just testing.
The testing is awesome till now: the phone is working more powerful with this kernel and doesn't get hot so soon. :good:
Oh, now there is something strange, the programs get FC-s...
The phone is on charger, I ran AutoGuard in the background in FullHD, Sygic and Waze in MultiWindow, VideoPlayer in popup with a FullHD video and SuperPlayer in popup with another FullHD video. It was extremely fine but after a few minutes the players collapsed and AutoGuard had an error. The system is stable anyway. It seems I have to restart phone now...
Edit: After restart I got an old problem back: Dropbox is unable to run again... I loved Perseus because of this, on Perseus this problem was away... I hope that I won't get the other issue back with my WiFi... And it seems, AutoGuard became stupid too... :crying:
I don't give up and keep on trying to make them ok.
But I can't find the thermal control feature in Trickster Mod Donation altough I have just a minute for it.
I am reading Trickster webpage to get ahead...
Question: Are You using Jedi ROM and have no thermal problems?
In that case I'm going to try that ROM, cause I'm on hunting for a ROM that works with no problems for me.
I tried some lately and till now Omega v18 was the best amongst them. I tried MIUI, ProBam, Hawkish in the last days and I get problems with all of them or had non-working applications and/or features which ones are essentials for me...
Edit: mmmmmmmm, as see there is no Jedi ROM for international N7100...

hey bro,
wow you seem to be a bit more advanced than me so maybe ive reached the limit of the advice i can give you.
However, if you inform me how to check for thermal problems i will surely do that and then report back.
the saber kernel to the best of my knowledge is underclocked so if you try to o/c it maybe that will prevent your fc's. I have read in the various threads, of which the community is very helpful, of some issues for heavy users due to the u/c.
Regarding the jedi rom i am a uk 7105 user and to the best of my knowledge i thought it would also work for international 7100 users?!?!
Here is the thread i use.

Thank You for Your effort!
I'll keep on investigating for a solution.
Unfortunately the real test was horrible with Saber kernel, when I tested it in car the temperature got high soon and the thersholds were low again.
But it's a good idea to try o/c thank You very much!
I'll try it tomorrow, now I have to go to play Cod4... :laugh:
And I found that TWRP is recommended for Saber and a few minutes untouching after the restart so I'll try again.
Have a nice day!

Thank You again!
I got some experiences with the newest Saber kernel and I like it 'cause the first kernel I can use 100MHz step with and using 300MHz step too.
It seemes to be good at battery consumption too. My only problem that this kernel doesn't support STweaks so I can't regulate charging voltages like I used to. Perhaps only Perseus kernel makes it possible as I can't get any other programs for it till now. Or NEAK kernel and the new versions of AGNi pureSTOCK kernel as I read their pages. I'll try them some day. But Perseus is my favourite.
I think it's important to say that the kernel isn't UC/OC by default so this doesn't make any problems and it's not UV-ed too.
I set min. to 100MHz and max. to 1920MHz to test and it's stable till now. I tried to Overvolt slightly and had no change on media programs behavior they don't like each other as I see.
Trickster Mod is nice 'cause it shows the CPU temperature which was helpful to understand this regulations of thermal control are needed.
When I tested it turned out that CPU is below 70 degrees while the battery temparuture is 'only' about 40 degrees.
So thanks for Your kind advises!

wow. Ok i think i understood most of your post. probably a little bit over my head but i need to learn.
I really like the new kernel im getting 1% battery drain an hour with the screen off which truly is unheard of for me,
The kernel runs real smooth apart from when i play asphalt 8. Or i should say it runs smooth playing the game until the phone tries to do something else. For example if it attempts to update a programme or if a message/email comes through. then the game just lags and i have to wait for the phone to stop multi tasking before the car starts to move normally again.
So im surprised to read you say the kernel isn't uc/uv by default??? I was pretty positive it was. But i dont know for sure and im probably not clever enough to figure it out lol.
I wonder what settings i would need to increase to aid the phone in its multi tasking? Also there must be some kind of programme we could use that would test our specific phone/cpu and tell us which settings it would prefer. As i believe each phone will run slightly different?
You are right i remember reading the kernel does not work with stweaks.
I wish i could work with you and figure out how to optimise our settings but i simply dont have the skill set.
I presume you used trickster to overvolt slightly?

No, I didn't overvolt at last. But once I tried and didn't helped on my problems.
Unfortunately now I'm back on Perseus kernel again 'cause some issues with Saber. It became crazy every time and locked my CPU on 160MHz only and only reboot helped.
The other issue was the stuck system server process what was active all night and didn't stop hard work.
Now I'm on reading the kernel's page till I get cleverer on it... then I perhaps try it again 'cause I liked it.

I searched the forum and saw some people had similar issues but nothing in the other threads seems to have fixed their issue.
I am having huge FPS drops in games after about 5 minutes of play time. I never had this problem when I was on stock, and ever since I have tried a few different ROMs and all of them have the same result. I found that if I turn my screen off for ~30 seconds the lag will go away for about 2 minutes but just comes right back.
Currently running SOKP ROM.
Games that I play are Valkyrie Crusade, The Gate, Heroes of Camelot.
Any help would be appreciated!

Ok, so the issue seems to only be present while charging. Does anyone have any suggestion on how to alleviate this issue without unplugging my phone from the charger? My battery does not last as long as it used to and I can only play for about a half hour before my phone battery starts to get extremely low.

Does your Rom allow for Changing of Governors and Voltages ? If so, then try Trickster Mod. If it does not allow such changes then switch to a AOSP Rom and then Flash KT747 Kernel by @ktoonsez. that kernel has profiles specifically tailored for Gaming.
That kernel was not compatible with AOKP Roms until Recently. I do not use AOKP Roms so I am not sure if AOKP Code has changed to make it compatible.

The app from the app store? I don't know anything about Trickster mod.

Yes its the App in Play Store. If you are not comfortable tweaking those parameters, then leave that alone.

Any recommendations on settings then?

Explore the thread on Undervolting / Overclocking in my signature. Let me know if you are comfortable with making that kind of changes.

I checked it out but it seems pretty confusing.. still not sure what settings I should change. Why would it be different from stock rom though?

In that case, please use the App "Fast Reboot Pro". It also creates a shortcut on your homescreen that, when clicked, will improve performance.
You may also want to apply V6 Supercharger Mod by @zeppelinrox.

My ROM is 4.4.2. Do I still need to apply the Ultimatic Jar Patcher?

I have not kept up with the more recent developments on that thread. Search the thread or post the question on it.

If your battery is getting low that quickly and easily your best bet, imo, is to replace it. Aa they age and lose capacity they also lose the ability to run the hardware effectively. Youre probably seeing lag because it just isnt able to provide the stable voltage required to run the cpu/gpu at full throttle very long.

I tried these modifications and I am still getting terrible FPS drops.

Your only other option is Fast Reboot Pro in lieu of Governor changes and Overclocking.
