I have weird screen issues with 2.1.2, when I go into the CM settings-> display-> custom automatic levels. The text showing the current screen brightness, the numbers show light screen tearing on both low and standard. Going back to 2.0.6 low voltage shows no issues
[myTouch 4G Android Development] dragone5:
I am having the same issue. Some animations or part of the screen get lines through them. Will go back to 2.1 for now.
[myTouch 4G Android Development] jdkoren:
Also reporting screen issues on 2.1.2, both SV and LV kernels. I'd try to get some screen caps but I'm vacationing and I can't run ddms on this laptop. Maybe someone else can do that so faux sees what's up.

Reflashed 2.1.0 in the meanwhile.
[myTouch 4G Android Development] gaww:
From all the posts since 2.1.2 came out - glad I did not flash it - still on 1.1.0 and staying there until several posts say all is well - lol.
[myTouch 4G Android Development] phaino00:
Flashed 2.1.2.1 lv about 40 minutes ago and appears smooth. Battery life is incredible...LOL. ;-P
[myTouch 4G Android Development] lanternslight456:
running 2.1.2.1LV with Royal Glacier and all is well!
[myTouch 4G Android Development] gaww:
Looks like faux fixed it.

Debating flashing it now or waiting on next nightly. Still on 17 and have not heard anything about 18. Not a crack flasher, but close enough I guess...
[myTouch 4G Android Development] phaino00:
Been running cm7 n18 with faux's kernel since yesterday. All was smooth until this morning when noticed first lockscreen freeze I've experienced. Waited 18 minutes and had to pull battery to boot. No proc/last_kmsg file available after boot. Flashed faux's new 2.1.2.1 lv kernel. All has been smooth over last few hours. GPS locked after a few minutes through GPS status app.

Love both cm7 rc2 + and royal Ginger 1.3. No real difference accept boot time and different internal storage numbers with same apk files installed. Just from my experience playing with them over the last days.
[myTouch 4G Android Development] xxpada:
your newest kernel the lv doesn't flash right stays stock on splash screen then I flashed sv that worked fine
[myTouch 4G Android Development] faux123:
Wow... sorry to hear that... you probably have the worst CPU chip I've seen/read on the forum... Won't even boot right :( with low voltage
[myTouch 4G Android Development] xxpada:
all your other ones haves worked.

ill try again maybe bad download

[myTouch 4G Android Development] faux123:
What are you running? CM7 nightlies?, RoyalGinger? GingerSense?

I heard/read Nightly #17 and #18 have started to cause Overclockers to crash more often than before, which means that the latest nightlies have something that uses more CPU power than before, thus causing those who's CPU is borderline to crash more often...
[myTouch 4G Android Development] irrelephant:
I have been on 2.1.2.1 sv on cm7 nb18 since I woke up and no problems as of yet! You never fail to amaze me with your work!

Cm7 rc1 2.1.2.1 sv

Just a quick question....

Im running CM7 RC1 on my MT4G. Will there be any kind of chance of bricking my phone or any kind of bugs if I flash the SV kernel on my phone thrugh CM recovery?
[myTouch 4G Android Development] xxpada:
must of been a bad download I reflashed now I'm good!
[myTouch 4G Android Development] phaino00:
You didn't just ask this question? There is always a chance.
[myTouch 4G Android Development] starcreamxb:
You recommend me doing it? I wan't to be able to have my phone running a little faster.
[myTouch 4G Android Development] :
I never seen a kernel brick and phone. Honestly only flashing a radio has brick a phone. As long as your phone turns on its not bricked and most likely can be fixed. A true brick is when your phone no longer turns on at all.
[myTouch 4G Android Development] darinmc:
Better to be safe than sorry, I've seen things other than radios brick devices. Somebody tried flashing a splash screen here and bricked their device. It's hard with anything, but never impossible.
[myTouch 4G Android Development] gaww:
I updated to 2.1.2.1 lv on build #17 with it overclock to 1612 and smartass governor. No reboots or freezes yet (had some on 2.1.0 yesterday on same build). H+ speeds are down about 2 mbps, but I am guessing that is a TMo network issue, so will check it a few times later.

Like the battery life with lv - trying to stay with them.

Update - H+ back up to 5800. I think a lot of "issues" with network speeds are at the TMo end and not the ROM's or kernels.
[myTouch 4G Android Development] SwornPacifist:
2.1.2.1 lv fixed my tearing issues. Running with CM7 Nightly 18 Colorized
[myTouch 4G Android Development] GazaIan:
Damn kernel keeps crashing my phone :(
[myTouch 4G Android Development] rojovilla:
Another outstanding iteration, faux...using the LV now and haven't had any issues.
[myTouch 4G Android Development] rojovilla:
What are you exactly doing prior to the crash?
[myTouch 4G Android Development] macheteZen:
During flash? Or will it boot? Can you logcat because it may help faux pinpoint if the issue is device specific.
[myTouch 4G Android Development] :
Its probably a bad download. Try wipping cache then dalvik cache before you install the kernel. When you wipe dalvik the phone will take longer to boot just wait once it fully boots let it load up then after 2 minutes reboot. Been doing that every time I flash the kernel.
[myTouch 4G Android Development] GazaIan:
The phone is locked. At some random times, when I wake the phone, the entire thing freezes. I end up having to pull the battery :( I used his Froyo kernel in RoyalLiquid, but this Gingerbread kernel is unlucky in CM7 :( my microbes live wallpaper crashes here too, his kernel used to fix it..
[myTouch 4G Android Development] faux123:
These types of posts don't help at all... try this:

[ROM] CM7 Nightly #18

[Governor] Smartass

[Freq Range] 245~1113

[Kernel] 2.1.2.1 low voltage

[Live wallpaper] Microbes

[Detailed Description]

I left my phone on my desk while I was sitting on the throne, when I came back, my phone exploded, killed my pet cat, caused my desk to catch on fire, burn down the whole building, creating a big sink hole which sucked in all people within 50 meters of it....

Something like above is more helpful than, my phone locked up... Because I can't read your mind, I don't know what ROM you are using and so on... :D

BTW, I am running CM7 Nightly #18 with Microbes running the whole day... I was away in a meeting when I came back, I can wake up my phone no problem. Running Smartass @ 245-1113
[myTouch 4G Android Development] phaino00:
BTW, I was running cm7 n 18 with 2.1.2.1 lv kernel while listening to Pandora, my screen was frozen when trying to wake. I use adw ex launcher with adw launcher deleted from system apps. The settings are smartass 245 - 1113 (your defaults with set on boot unchecked). Again no proc/last_image after boot up.
[myTouch 4G Android Development] faux123:
No last_kmsg usually means its not a Kernel related issue... Maybe its related to ADW EX launcher... I use LPP myself (and it froze once in a while, but FC/restart App fixes it), and it seemed all these "home launchers" have some compatibility issue with Gingerbread... When I use the same LPP with my Froyo kernel, I had zero issues at all...
[myTouch 4G Android Development] phaino00:
Thanks. As anyone spoken with Anders about this? I'll drop him an email.
[myTouch 4G Android Development] everest.deth:
Well im running lpp and i get the same lockup on the lockscreen :(

Oddly changing cpu governor fixes it D:

Sent from my rooted glacier running CM7 and the honeybread theme :)
[myTouch 4G Android Development] gaww:
If you had CPU low/high settings really spread and had a governor set before flashing the kernel, these settings carried over could cause crashing - I did it once myself.

Flashed a different kernel, re-did CPU and governor settings, and then reinstalled this kernel exactly as instructed by the OP.

I am assuming you did a clean wipe if you came over from another ROM category. If not - you have a mess that needs cleaning up.
[myTouch 4G Android Development] jdkoren:
I've gotten the unresponsive (and upside down) lockscreen a couple times before. Letting the screen turn off and turning it back on again would fix it for me, so I haven't had to pull the battery yet.
[myTouch 4G Android Development] epsix:
Faux123,just letting you know the wireless modules does not pick up 5ghz band for wireless N on both GB and froyo.
[myTouch 4G Android Development] xboarder56:
Faux123 is there a chance i could a boot.img of your kernel i can add the modules by hand
[myTouch 4G Android Development] faux123:
It works in my GingerBread kernel... Here's my screen shot:

dd-wrtN5 is my 5GHz wireless-N Router :D

Froyo WiFi driver is older and so Wireless N is not supported by it...
[myTouch 4G Android Development] epsix:
Weird....some how when I flash your kernel the files does not get push through let me try to push it manually. Thanks
[myTouch 4G Android Development] gaww:
My 5GHz works OK also on this kernel.
[myTouch 4G Android Development] gaww:
I am seeing this i believe. had not gotten any freezes or reboots before (except when CPU settings and choice of governor were not as instructed in the OP), but have seen some since flashing 17. Am using lv version because of better battery life, and will stick with it if only occasional freezing.

I am overclocked to 1612 with smartass governor. May try backing down some if that would possibly help with the occasional freezes.

[myTouch 4G Android Development] AlexFG:
tried this on CM 7 RC2, played around with it for a little bit but it kept freezing my phone and making it act weird so I went back to the stock kernel that came with my ROM after two hours.
[myTouch 4G Android Development] gaww:
Did you have SETCPU active and/or did you have performance CPU settings overclocked with a low min speed? If so, this can get you freezes and reboots until you activate the smartass kernel or up the minimum speed per the OP instructions.

To faux - if you believe these may be causing this - you might want to add a warning to reset and/or uninstall or freeze SETCPU first before flashing this kernel.

I would be glad to be a beta tester for you, faux. I have experienced the freeze issues and I know I would be a good tester for you

I downloaded the newest LV version four times....everytime I try to flash it, it aborts saying (bad)
[myTouch 4G Android Development] graffixnyc:
Faux.

I installed the LV kernel (same I've been running with no problems) when I flashed this latest version boot screen came up, prompted me for my sim pin then turned off. Wouldnt go back on until I pulled the battery, tried again and same results. I went back to the previous verison and it was fine.

running cm7 built 17

governor interactive min 246 max 1516
[myTouch 4G Android Development] macheteZen:
LV kernel looks, feels, and runs great on nb21, thanks again for all your hard work faux.
[myTouch 4G Android Development] ydizzle:
I downloades the SV version and installed fine on first try.....i want the LV lol
[myTouch 4G Android Development] gaww:
I am on latest lv. I used on 17 and now 21 - no issues yet (I had been getting occasional freezes with prior version on 17).

I am trying minmax governor for first time - will post results (which will primarily be battery life vs smartass).
[myTouch 4G Android Development] AlexFG:
I did it through performance > CPU Settings I tried Max 1.84 Min: 245 with onDemand Governor but it obviously crashed on my first reboot just like OP mentioned.

So I triend Max: 1.8 ghz Min: 1 ghz with smartass governor and it crashed randomly. I tried playing around with max/min frequencies but my phone kept acting up freezing and when people called me the phone kept vibrating throughout the call.

So I went back to the other Kernel I was using and that fixed my problems.
[myTouch 4G Android Development] jdkoren:
Not sure why everybody wants to max out their CPU frequency when 1GHz is already plenty. I'll go 1.2 usually, not really any reason to go more.

Anyway, I'm not sure if it's the ROM or faux's kernel (or something else I hadn't considrered), so I'm posting in both places. Sometimes after a reboot the phone thinks the SD card is damaged and it doesn't mount. I have to go to Settings > Storage and click Mount SD card, then everything's fine. Doesn't happen all the time and it's not causing me any trouble, but eh.

Looking forward to flashing 2.1.4
[myTouch 4G Android Development] gaww:
I would bet 1.8 in combination with the newer ROM is a bit much.

Did you try a more conservative setup to see if it was stable? I have run at 1.5 and 1.6 on the lv 2.1.4 kernel, and it has not even hiccuped yet. I am currently trying the minmax governor.
[myTouch 4G Android Development] gaww:
WiFi and Bluetooth combined issue

I have noted problems with having WiFi and Bluetooth activate at the same time. WiFi disconnects in the router room (not Bluetooth).

This has started happening only recently. I noticed it with this and the previous kernel starting (I believe) with Build 17 and through 21.

Never ran into this before.

I am on 2.1.4 lv and minmax governor (also did so with smartass kernel) with 368/1612 CPU setting.
[myTouch 4G Android Development] AlexFG:
The whole idea behind modifying your phone, installing a new ROM, kernel.... etc; is to find out what your device is capable of doing beyond the limits of the stock ROM that came with it. So trying to squeeze the last bit of power out of your little toy makes a lot of sense to a lot of us in this forum.
[myTouch 4G Android Development] AlexFG:
I went as low as 1.7 ghz for the max and tried a few governors but it was still too unstable for my taste and crashed every now and then. So I just went back to the standard kernel that comes with CM7 RC2, right now I'm at Max: 1.5 ghz and Min: 245 mhz with the onDemand governor and everything is working just fine so far.
[myTouch 4G Android Development] gordonzhao:
Faux, awesome work! When I first got my MYT4G, battery life was not even tolerable! I can now make it through the day with your kernel! Awesome work mate!
[myTouch 4G Android Development] Kensei22:
if im looking to save battery and OC, but not to high, is this kernel better then the stock CM7? also im not going to OC to 1.8GHz just to 1.4 or 1.2. so would you recommend it for my reason of just battery life? and should i get the low voltage or the normal stock voltage?
[myTouch 4G Android Development] gaww:
Low- if it is stable.
[myTouch 4G Android Development] gaww:
If you had tried 1.5 it may have been stable.
[myTouch 4G Android Development] jdkoren:
It's a question of capability versus necessity. CAN you do it? Sure you can. Do you NEED to do it? Thus far, for me, the answer is no. If it runs so smooth already at 1.2~1.3, what do I need 1.8 for?

I couldn't tell you if there's any performance difference between CM7 kernel and faux's. Regarding battery life, try out the lower voltage (LV) kernel. Supposedly different phones may tolerate it differently, so no guarantees, but all his LV kernels have been running fine on my phone.

[myTouch 4G Android Development] gaww:
I am still getting disconnects with both Bluetooth and WiFi on during calls. I am going to flash 22 and see if it also happens without the kernel (using 2.1.4 lv). Then will reflash the kernel and see if it still disconnects.

Having otherwise stable performance and good battery life (as with smartass governor) with the following setup:

Build 21

Kernel 2.1.4 lv

Minmax Governor

minmax settings 368/1612

SETCPU on with above settings and set on boot - no profiles

Performance Settings/CPU not set on boot (they are mirror of above).

I found that Performance/CPU settings alone did not seem to stick without SETCPU set with smartass governor - frequencies stayed at smartass default.

Smooth as Silk

Flashed last night and so far phone runs fast and smooth, no issues so far.

Thanks Faux123 another awesome kernel!
[myTouch 4G Android Development] Ghost117:
Hey. I absolutely love this Kernel, and was hoping to take advantage of the CIFS capabilities. But honestly I am not too great with linux and I don't know how to do this because everything I found so far assumes that you are either using a kernel without CIFS support (if I understand what they are saying) or are using CM6. I am not sure what the differences would be and was hoping that maybe someone here could point me in the right direction.

Thanks!

Should of been the stock kernal

my wifi stopped working on 2.1.4 LV but fixed that with SV and now going to 2.1.5 LV...cuz having a all day battery life is like finding a pot a gold lol
[myTouch 4G Android Development] Tazzaras:
My wifi was working fine on RC2 using 2.1.2.1 kernel but ever since now everytime i hit connect to wifi it gives me error. No explanation or anything just error where it should show the network it's connecting to. Any advice on how to fix this
[myTouch 4G Android Development] KNK:
I find turning off the wifi and clearing the cache with a kernel re-flash usually helps with that. After rebooting twice I will turn on the wifi.
[myTouch 4G Android Development] Tazzaras:
Yea I do that usually anyways, and I did that twice, still no luck, its weird. I hope I don't have to reflash the rom that would suck...
[myTouch 4G Android Development] macheteZen:
Just a little info if people run into the problem I was having. I did a fresh flash of cm7nb23 with kernel 2.1.5. Upon reboot it loaded fine I enabled wifi (to dld app) and instantly it rebooted, which was not unheard of new flash and all. Then as it booted back up I got lockscreen for a second, and it fell into a boot loop. :confused: So I started a logcat (faux looks here :D) and let it loop for a few iterations, looked like a wifi connectivity issue was causing it. So after it finished the boot animation, I immediately held down the power button and selected Power Off, which it did. I got all ready to post my issue and logcat on here, when I Powered On I noticed it was fixed, so lesson learned Boot Loop does not count as two boots. :p Thanks for all the amazing work @faux.
[myTouch 4G Android Development] :
Runs great I wish Google would fix YouTube to make it work properly on gingerbread. Play videos when the screen is off. Not a problem just puts the phone in a sleep state which wont wake for awhile. Has to do something with the screen off animation.

dude your phone is all messed up... you have serious permission problems... Fix permission from recovery and if that does not clean it up, you might need to re-install the nightly from scratch after FULL WIPE... Your logcat is full of permission issues...
[myTouch 4G Android Development] macheteZen:
Thats strange because I always fix permissions after I flash. And then again once more in ROM Manager once it boots. It runs fine now that it restarted. Thanks for looking you are by far one of the most responsive and knowledgeable devs I have had the pleasure of communicating with.

WiFi stopped working

ok so my WiFi has stopped working completely...it turns on and off but doesnt scan at all

i tried everything on how to make it work...from doing a full whip to going back old kernels and old nightlys and nothing works....if anyone has any ideas on how i could fix this it will be highly appreciate....PLEASE!!!! :(
[myTouch 4G Android Development] gaww:
Some posts had said to simply wipe data in the application and reboot, but you are way past this point. Since your post is in this thread, I assume you were using this kernel when it went out.

Exactly what did you do to do a full wipe? That would be fastboot erase -w, factory reset, and possibly format /system.

After a really clean wipe - if you had a recent nandroid (ROM backup from recovery) that had worked, you could try it. I had a nasty WiFi would not connect problem a while back, and restoring the nandroid did not fix it until I completely wiped everything (but the SD card - nothing to do with it).

I was also able to get a clean install after a full wipe with WiFi up - always checked the WiFi first until I flashed Google apps or anything else.

I have had no problems connecting to WiFi with this kernel, and have tried most of them (versions).
[myTouch 4G Android Development] itzsmokey:
before the problem, i would always wipe cache partition then Wipe Dalvik Cache then let it boot and load, then reboot a 2nd time

when the problem showed up i did a full wipe with clockworkmod 3.0.0.6 and just flashed nightly #22 and that didnt help

then i did everything again and flashed the kernel and that didnt help....

and now if i wipe and flash nightly #23 it keeps rebooting on my when the wifi is on

and i just notice that i have the same problem on my girlfriends phone but after awhile it connects
