[Q] Kernel issues.

So I just flashed Decks which has a Cyan kernel. For some reason my phone doesn't seem to like when I try and flash anything that doesn't come with the ROM I flash.
I've tried multiple AOSP ones that support undervolting, no dice; will not even boot.
I clear cache before every attempt, no dice.
Any suggestions?

I'm not a 100% on what you said but if your trying to under volt an aosp kernel you can try sz 2.2.1 or tiamat they are the only 2 I use because I use the sbc versions but like I said I'm not that clear on what your question was.

Wow, re-reading my post I see autocorrect didn't do me any favors.
I've tried both SZ and Tiamat and I can't get either of them to run on my phone. After clearing cache I flash either of them and if I remember right SZ never gets past the white HTC screen before rebooting and Tiamat (if I'm lucky) will start to load my ROM before just locking my phone up.

It's important to clear cache and dalvik cache before flashing a new kernel. I use SZ 2.2.1 with CMod ... works great with interactive x governor. I don't undervolt, simply use 245/998, and haven't had any issues at all. Might give it a try ... good luck.

Try wiping cache & dalvik again after flashing the kernel. You can also try different versions, perhaps the versions of Tiamat & SZ that you used just don't like your phone.
Also, if you have SetCPU set to "set on boot", uncheck that option before flashing a new kernel.

I do clear both. I reboot the phone and it either never loads the ROM or starts to load the ROM and locks up.

Tried wiping after kernel install, no dice. And I don't have "set on boot" checked.
Grrr, I don't get why my phone doesn't like flashing kernels. Maybe I'll move to a different recovery and try...

Tried RA - no dice. Now rather than locking up the phone just reboots constantly. That was Tiamat, going to try SZ...

Try wiping cache & dalvik cache then changing kernel. If that don't work, wipe everything except for sdcard then reflshing the rom.

I was having the same problem with the Smartass govenor.
Change it in SetCPU to performance and see if that works.

my present kernel is tiamat 4.0... maybe other kernel ???? which kernel???
and not tested SetCPU i need try this...

I saw ur on ics right now there is only one kernel tiamat 4.1.0 modified so u need to try changing governers or install your apps one at a time from a clean install and find the culprit
We are legion, for we are many

Reboot
Does it reboot after a clean flash? or only after you load apps / restore data?
Like was stated:
Wipe Full
Wipe Cache
Wipe dalvik
Flash Rom
I had no reboot issues, just standard ICS bugs.
Maybe try to download again and then flash?

I'm flashing the Tom with indicate instructions but the reboot continue.
Although, changed the rom miui and run best, changed setcpu at performance and good... the reboot is less.
Only try change to kernel, Wich kernel improve my phone?
Tanks.guys

Hey,
Give it a full wipe "Data Davlik and Cache" and try flashing a differnt rom and see if that gives you any different result.
Did you flash a different kernel or are using any tweaks or mods OC or anything like that?
Because they have been known to cause reboots if not used right.
Stevo

Tanks for you opinion. With miui rom not reboot to much, I think that this rom is the best choice for me.
But with other kernel must be run best...

Lightest/Most power effecient ROM?

Hi guys, whats the most lightest/power efficient stable rom which will give me good battery life on desire Z?
I have yet to root im on 2.3 gingerbread Offocial

Try them all for a few days and make your decision; what's "good" for one isn't necessarily "good" for another due to each user using their device differently. That being said, I've heard good things about G-Lite.

Some that I can think of off the top of my head aimed more at battery/performance improvement:
G2 Slim : http://forum.xda-developers.com/showthread.php?t=1324616
EliteMod CM7 : http://forum.xda-developers.com/showthread.php?t=1246682
Though won't be much new changes to it since he's on EliteMod ICS now, which I love for the lightness/performance. Check the link in my signature if you want to try the ICS android version instead.
Virtuous G-Lite: http://forum.xda-developers.com/showthread.php?t=1349030
Kind of the long running 'light' rom for a while.

Ok
Ok so I decided I want to get the
Virtuous G-Lite ROM
But I'm new to all this and I dont understand what steps I should take and even what half of these words mean when I tried googling it
Can you please put me on the right direction ?
and will the Virtuous G-Lite support my UK Desire Z phone ?

Okay search for glite in the development forum and download the rom. It should be around 120mb. Then copy it to your sdcard. Don't put it inside any folder nor should you extract the zip file. Now reboot your phone into recovery and wipe data, cache, dalvik. Then choose the option to install zip from sdcard. Select the zip file which you copied earlier. After flashing reboot your phone. This information is based on the presumption that you have successfully attained root and s-off on your device.
EDIT: As you haven't rooted your phone yet I suggest you follow the link "minus" below in my signature. There download the appropriate pdf.

hokay
Ok im in Glite now and I dont see a android notification bar
like without one, i cant do anything much so i need to go to a different rom do you know any?!
and I dont want to do a kernel thing because I dont understand it and i dont want to brick this phone

problem
ok the GLITE rom is giving me problems because it wouldn't log in to my primary gmail account for the market, so I used my other account and now i get an error message everytime I try to download something from the market.
Do you recommend any roms out there or should I try Elite rom, but once again I dont understand this kernel stuff its worrying and i want battery life atleast
edit: I dont like go launcher pro it doesnt have the android notification bar
Edit 2: 20 mins later, I cleared the cache, dalvik etc then I went to the launcherpro site and got the latest one and my notification bar has returned (or just come) how ever market still doesnt let me download anything

did you wipe everything before installing the rom? you may need to clear market data/cache
settings>apps>manage>play>clear

I would like to try it but I dont understand any of the elite kernel stuff

you flash a kernel the same way a rom, just flash rom then kernel. elitemod cm7 has both kernel and rom
http://forum.xda-developers.com/showthread.php?p=17219499
in the second post you will the download link
put it on root of sd card
boot into recovery and wipe everything (superwipe or fastboot wipe even better)
then flash zip
then reboot
sign in
reboot
your ready to go

oh
Ohhh so when I try to install the ROM the kernel will be installed along side it right?! that means its going to be easier than I thought.
what is this super wipe?

yes, many roms come packaged with a kernel, some don't, some require extra packages such as gapps to be flashed as well. the link I sent you just need to flash the rom, all is bundled.
superwipe came about in the g1 days, orginaly by osaka. it runs a script to wipe your phone clean to help insure a good flash of the next rom. there are many variations but I suggest finding one that formats system/cache/data to ext4 as well as wipe
search for superipe+ext4 in the threads
and fyi fastboot -w is an even cleaner wipe but needs to be done at a computer and learn how to use fastboot

GLITE Has this bug where it wont show the notification bar on first boot. One reboot will fix it. Also glite is bit old in terms of ease of use(customization) but it is very good in terms of battery. Elitemod is good too.

Yeah that bug happened to me, I tried to clear dalvik cache and then I updated the launcherpro then it randomly came. Is elitemod more easier and more customisable?what android version is it? Because on glite the battery life is brilliant but it feels like I'm sacrficing widgets (power control), the quick settings I had previously and the overal look is quite 'boring'
So with elite mod would I need to do any overclocking what so ever or anything else? And how can I make a back up of my current glite installion and revert back to it just incase elitemod doesn't work out for me

well your first step, just like when changing to any rom, is boot into recovery and make a backup. then you want to do a full wipe. then flash the next rom
nik3r has made a couple versions of elite mod, the one being suggested to you is based off of cm7 so its gingerbread, same as glite. it is slightly overclocked out of the box and has just about all the options avalible for a rom of its day, far more than glite. as for battery life, if you keep the oc/uv settings as they are you should get just as good battery life. I'm a moderate to heavy user and I do just fine with it

Help with MIUI v4.

I am kind of new to this and it this has been frustrating me all day. I had CM7 on my HTC Evo 4G for a while and it started to run slow so I decided I needed something new (other then a new phone). So I tried MiUi (latest version) and I loved it. Ran smooth and was quick. I installed my titanium backup and it was not getting root permission. I tried installing busybox (wouldnt install) and i also installs CWM and Super User. Nothing helped. Someone had told me I needed a Kernel. So I went and tried a couple. I tried the Mason Kernel and the phone would just give me a blank screen. The only kernels that worked were Tiamat Kernels, the SBC ones lagged heavily straight off the bat, the other 2 did not lag at first but after a few minutes it started to lag heavily as well. Then afterwards MiUi would not respond. What am I doing wrong? Honestly I just want to restore my apps with titanium back up and have it get root rights. What do I do?

OK, that was stupid advice.
It's pretty simple actually, after you reflash the ROM, go to Supewruser app and set permissions. Hit menu and make sure permissions are on. Then you have to reboot

Yeah^ if that doesn't work, I've found that the super su app works. Also, Mason kernels are basically an updated tiamat kernel(s) but ATyoung kind of made it his own. But thats not the point. HipKat, good advice man. :good:

[Q] Custom ROM's to laggy.(solved)

Hi all. I tried to search but didnt found any solutions.
So. I tried to install custom rom's on my one v(gsm). And i noticed that phone became really unusable. For example: sometimes i cant answer the call because of lag, or cant shut down alarm. It can stuck for several minutes. I noticed that behavior in CM10 and MIUI jb. Now im using myONEv RC7.0 rom. It lag less,but it have already stuck twice per 36 hours of using it.
Using RIGHT kernels for EACH rom. For CM and MIUI Hellboy's kernels for CM10. Flushing whith full wipe. Using min cpu freq. at 368Mhz and interactive governor. Tried to overclock to 1.5GHz no result.
So do you have any ideas to fix it?

Having the same problem I've tried every ROM I could find. They all look better and can be customized more that stock but lag is a problem... I'm thinking stock is better. Camera is also a problem the stock camera is amazing compared to the rest imo. Hopefully there's one ROM out there.

As for me, camera is not a problem. It quite good in non sense roms. Finally, you can use any camera app from market. But im really waiting for cyanogenmod 10 working good on our device.

Backup ur data n format memory card then flash a custom rom... Then it ll be bit faster(sense roms r bit laggy try jb)
Hit thanks if I helped u!!!

Backup ur sdcard then go into recovery and format everything except sdcard.
format/emmc
format/devlog
format/cache
format/system
format/data(include anything that's been left)
sd-ext format will give error.don't worry.nothing's wrong.
And also do a full factory reset. also wipe cache and dalvik cache.
Now,flash ROM again and use correct kernel.
Try using ondemand instead of interactive. first try ondemand at 1ghz-1ghz then if no difference try at higher values.
Also try wiping sdcard if still no difference.or try a different SD and see what happens.

I've thought about formating sd card, but has no idea how can it reduce performance. Ok. I'll try to do that today in the evening.
If somebody with same problem already done it,write about your results. Thanks.

Also try this,it reduces lag significantly-

Thanx to all for support. Formating SD card and using seeder apk solved that problem. So everybody with same problem- format your SD card, delete second partition,if it excite, flash with full wipe, and then install seeder apk, from link above.
