DoomLord's approach is probably wrong, but we do not know what exactly is wrong. His overcloclocking method looks like "brute force" leading to higher power consumption no matter how you are using your Ray, even if you are not using it at all.

aire doesn't modify any frequencies tables in source code, just cheat some part of a kernel showing it than it's not a Ray, but Arc S (oh yeah, you don't get an Arc S for free anyway :D ). So we get frequency range as it designed by SE developers. Than he add some good governers, apply extreme but stable and tested undervolting, and we got that brilliant... oh, sorry... pure emerald[1] :D kernel.

Combined with clean REPACK4PDA rom, this kernel give you good starting point to set up your SE Xperia Ray (which me personally assume as one of the best smartphone today) to work fast and long.

[1]About "PureEmerald" name, as we call this kernel on 4pda.ru. There is a tale by a greatest russian poet A.S. Pushkin, "A poem about tzar Saltan". This is a small part of this poem translated to english:

Here's a wonder, though, worth telling -

There's a little squirrel dwelling

In a fir tree; all day long,

Cracking nuts, it sings a song.

Nuts - most wondrous to behold!

Every shell is solid gold;

Kernels - each an emerald pure!

That's a wonder, to be sure.

Bluetooth again ..

.. like so often: nice image with cool features - but I don´t get serial ports from the connected bluetooth device on my pc (to sync with myphonexplorer, works good using stock firmware ).

Same issue in CM7: some versions creating these ports, some not. Maybe I have to change some settings on the phone, any ideas ?

I also have tried to install gapps-gb-20110828-signed.zip, but the market did not appear in the app list.

But anyway: one day it will work and I say THANK YOU :-)

Is there a way to get the quickpanel in stock firmware, just in case.. I don´t believe it is only the QuickPanelSettings.apk right ?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:

need 2 files: SystemUI.apk (with replacements) and QuickPanelSettings.apk. This is offtop))
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Kaskade:
Good to see new devs with somewhat new approaches of modding. For example, i love the "keep it stock" way you guys do this.

Flashed just the kernel, the battery life is great and call recording works flawlessly, so.. thanks! :-)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] 37_:
I confirm the battery drain with doomlord kernel is very very very fast, even in flight mode without any activities and default clock of 1 ghz :mad:

now I will try your kenel
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] ImmortAlex:
Hmmm... It should work. The only problem with gapps is the need to reinstall it each time after installing update to repack4pda. But after reinstall everything works fine for me.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] suur13:
Installed v5 kernel (on stock .58 HK ROM, which is manually cleaned from bloat).

Works fast and stable, but no noticeable battery life improvement. Still drains 1% per hour at night, when it is laying on desk idle (Wi-Fi turned off). So no deep sleep I guess..

Battery stat. is showing that 65% is used by "Idle process". Shall I adjust something ?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Patshad:
After installing gapps-gb-20110828-signed.zip, you need to manually add a google account under accounts and synchronization. After that, the market is there :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] speola:
That was the missing link ! Many thanks !!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
Just some changelog that i found from using 62 firmware compared to 42 firmware. Changes are:

1. Memory management is better, no more crashed phone (well my sister's active got that problem but since 62 arived it is better and smoother)

2. Baseband 64 is better in reception (at least in my country) with old baseband it is unstable.

3. Your friend's avatar is displayed for each messaging thread if existent.

Did not know anything others.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
overclock? use SetCPU app.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] thelegendofpiter:
thanks a lot, last question, can i update the basebands (i do it with flashtools right?) after the installation of the rom?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] KristianKenneth:
Yes.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
From the Google stuff, I only want Market to work. So I downloaded the market.apk on my PC, transfered it to my Ray and installed it with the explorer. When I want to open it, it says an account has to be configured first (ofcourse). When I accept, nothing happens and it just returns to the menu. When I want to add my Google account via settings, I can only add an Exchange account??

I'm guessing this can be solved by flashing the gapps addon, but I would like to keep my Ray as clean as possible. So now my question is, which .apks inside the gapps addon are really necessary for market to work and to be able to configure an account? I don't need the other Google stuff, so I'm going to delete them out of the .zip.

Thanks in advance!

PS: Thanks for the ROM and kernel!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] KristianKenneth:
Because market app has some dependencies included in the gapp package like sync etc. So when you try to sign in, it actually opens an apk which isn't there so nothing happens. You must install them too. To save you time to sort things out, just install the whole package and uninstall what you don't want after thru titanium backup or whatever app there is that can do this.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] geekoo:
I would only remove that which makes sense to me and leave the rest in, as opposed to retaining only that which I want.

For example, if I need only gmail and don't want music. And if the zip has gmail.apk, goog.apk, music.apk...

I would remove only music.apk and leave the other two in. This way if gmail has a dependency to goog, I don't break it.

Just my 2 cents.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
good idea to keep phone as clean as possible.

our guys just copy two apks from gapps to /system/app with corresponding rights, this is GoogleServicesFramework.apk and Vending.apk. As I heard from our guys this works.

you can. but note that baseband bundle contains own kernel. you should in this case check 'Exclude kernel' checkbox. otherwise you should reflash your custom kernel.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
Thanks idareyoutoclickthis, geekoo and especially coolkaas! :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] thelegendofpiter:
EDIT

ok, thanks! now i have te .56 but the battary drains too faster, what i the best baseband now?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
I feels absolutely same!! :) now I revert back to 64. before I test 58 bb and battery steels drain. I don't know what happens..

our guys reports that all is ok.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
.62 is doing fine for me..
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] juer_liu:
I use .64 firmware and v7, all things run smoothly. But when the phone connects with win7 64bit, the mtp usb driver doesn't work :-(((

there was not such status with .58 firmware.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
I'm really confused now, is it .62 or .64?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
baseband is 64, firmware is 62 :)

last 4pda rom (v.7) based on 62 fw from se. it (rom) compatible with all last basebands -- with 56, 58, 64.

64 baseband come to us with 62 firmware. :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
So what I wrote in my signature is correct? I always thought the last 2 numbers stood for the baseband :p

Btw, I have an issue with the vending.apk. When trying to use the market for the first time after configuring my account, there was a FC of the vending.apk. I reinstalled the market app (not vending.apk) could use the market for a few minutes, even installed MX video player, but then another FC and now I can't start Market anymore, it immediately crashes.. I downloaded the 3.4.4 version of the web, or would the market app also have been there with only installing the vending.apk and the googleservicesframework.apk?

EDIT: No difference when only flashing vending + servicesframework and not my other downloaded market. Vending.apk keeps crashing.

Thanks in advance!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Ridho1:
.64 is the best. You should not worry bout the battery. If you take a look around, all of smartphone drains battery fast. Just dont too worry. :-)

I use .64 baseband and this Rom and kernel. It eats 1% for hour when the screen is off (with WCDMA and data traffic enable).
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] thelegendofpiter:
great! now i flash it
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
Nevermind. Got it working by flashing it (with all other stuff deleted out of the zip) instead of installing them as regular apps.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] alanllew:
Is anyone else having trouble with data on this? I noticed the setting to retrieve internet settings has gone from under the Sony Ericsson tab in settings, and no matter how I set up my apn (XL Indonesia) I just cannot get mobile data. Any advice? Thanks!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
I still have the download setting hm sony ericsson menu bro. I am using the one from seus.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] alanllew:
Thanks for that. I guess I will switch back to another ROM and clean it out myself. I was loving this Repack version though!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Ridho1:
I had backed up my apn with titanium in previous rom then restored it after flashing.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] alanllew:
The apn setting didn't seem to be the problem - it's pretty simple to set up a new apn. I just couldn't get online at all with the Repack v7. I downloaded aire's linked .62 rom and it worked fine immediately though so all good. :D
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
guys, here new kernel by aire for you. really it not new, we already test it some days (about one week). it use DoomLords' custom table for voltages and frequencies. kernel is good. not more consumption than at previous uv7.1.3.

there are frequencies above 1.4 ghz!! :)

it is here: boot_uv7.3.5.img (hotfile.com hosting)

and here: boot_uv7.3.5.img (mediafire.com hosting)

you can update on it, or not do this, it not obligatory updating.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
Wow are you sure it's not adding power consumption?? :) I'll try it soon :cool: Now the problem is, i haven't found aire's post that is left unthanked.. X)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kizsleg:
thanks for the update. can you upload it in mediafire? will hit thanks button when im on PC.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] funiewski:
Hi, aire made a kernel for miui some days ago, do you think it is possible for him to port this one to miui too?

Thanks for your efforts!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
coolkaas, just to report --> i got boot loop with 7.3.5 kernel :( I had to revert back to 7.1.4.img to get the phone running again. Is it because of set CPU on boot or something else? I use setCPU at stock .62 ROM and set 1.4Ghz on load. Thanks for any support.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] coolkaas:
for a week of testing we can't see consumption increasing.

I have updated my previous post. add mediafire for you.

aire made two kernels. this discussed kernel (for stock, for our repack) and miui kernel. _both_ based at DoomLords' static voltage table. you can download it and use!

guys! this is not my kernels! press Thanx button under aires' messages. :) I only bring what aire made.

hmm.. two our guys has reported for same problem. I don't know why this happens :( for all other our testers this kernel works fine.

I think, setCPU don't initiate bootloop because it starts much later than loop occurs..

so you can try uncheck box 'run at start' in setcpu, (and reflash new kernel) but I think that is not the point.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
Or maybe, the default range is too high for some phone, or the kernel is too doomLord modified (certain driver missing). Thanks for the report, hoping for some fix. Thanks btw. :-)

Ps: can ADB logcat used to report kernel error? I haven't tried but if it can be done i'll do it.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] funiewski:
Do you know link to the new miui kernel?

U got thx for usefull posts :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kizsleg:
thank you very much for the MF.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bazonga:
No bootloop for me and indeed OCable to 2Ghz :d
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] 8f86TcLjmt:
Updated to kernel 7.3.5 - works well. May be kernel shouldn´t overclocked by default but its just a suggestion.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kizsleg:
im also stuck into bootloop in 7.3.5. im running .42fw and 56 bb.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
i retried just this moment now and still got bootloop eventhough i remove set at boot CPU Master.. :( adb logcat does not report anything too.. hope aire can investigate with some other test user who got bootloop too..
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] KristianKenneth:
Bootloop too with 7.3.5. with my second attempt I did a full wipe and still in reboot.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sirkay:
have you try this miui kernel by aire? here

i managed to get almost 2days with 5-6hrs data enabled
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] funiewski:
Thx, but I have this one, if u see above there is option for higher frequencies than 1.4 in the new kernel.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] aire:
Look at this: http://xdaforums.com/showpost.php?p=21755683&postcount=49

2 All:

We need to limit max freq to 1,6GHz in next kernel build, for solve bootloop issue.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] KristianKenneth:
Aire, why do some experience bootloop in your current v7.3.5 kernel?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] aire:
Because the starting frequency is 2 GHz. After the initialization startup scripts are limits on the frequency. Not all devices can run at 2GHz.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
:double post, the same with aire's answer :o

@aire: We're waiting for 7.3.6 one :) Thanks for the update!

can i checked "exclude kernel" in the flashtool so that i will not flash the kernel again? can anyone share a backup of .56 or other basebands in case i want to revert it. TIA!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] ImmortAlex:
Just flashed 7.4.4, set max freq to 1.6GHz and tested it with Raging Thunder II - the game, that not only stress CPU, but also use our GPU. Works stable. But became warm!

Check posts by aire in this theme. He gave links to all basebands in one list.

And yes, if you check "exclude kernel" or not select kernel.sin in list, your kernel will be untouched.

After having run this kernel/rom for a week I must say it's great, however I found two bugs, any help much appreciated:

1) sometimes shows up with a missed call eventhough the mobile did not ring/vibrate.

2) battery charges up to 98% only. I've let the device discharge completely twice and charged it both times for 5 hours; it shows 98% top.

Before I try this, should my battery be fully charged before wiping?

EDIT:

interesting enough I put my mobile on charge at 95% and left it there for another three hours and I got 100% in the end.

Perhaps I was wrongly assuming that 5 hours were enough for a complete full charge.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kizsleg:
is this what you want to point out to us?

can you elaborate more clearly on the changes and improvements for the new kernel? :)

im not a developer that's why i dont understand what the changes means.

how much extra ram can we get?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Kaskade:
I notice that the cpu frequencies changed to those of the other developer kernels...

Are you planning to change those to stock frequencies once the kernel leaves testing and gets into stable stage?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hansip87:
I don't think it's possible. Because afaik, if you implement stock table, you can only get 1.4GHz. But if we use doomLord's table, it will get to 1.6GHz. Aire's statement was that via testing, they conclude that the latest table from doomLord is low power enough now. So no necessity to go back though.

I'm running 1.6 Ghz and it's fine and dandy (so far). How do we know that 1.6Ghz may damage our phone? is it because added voltage or something? AFAIK as long as no added voltage and it's running stable, i don't think it will damage the device.. :-/
