Help needed

Hey [MENTION=411194]BlackAfghan[/MENTION], I tried installing the twrp for Pollux using the CM recovery and I got this error message (attached with this post).

I downloaded the twrp for Pollux from this page:

http://xdaforums.com/xperia-tablet-...very-twrp-2-8-7-0-pollux-polluxwindy-t3187811

The one I downloaded is:

TWRP-2.8.7.0-pollux-20150823.zip

Is there anything wrong with my ROM? I'm almost a newbie but I can work with things with some proper guidance. But this is something I don't understand.

The error says the twrp is for SGP321. My device is xperia tablet z LTE (SGP321) Then why this error?

I've also attached a screenshot of "About tablet" section of my tablet.

Can anybody help me out with understanding what's going wrong here?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Looks like a PAC issue, you have to perform a manual installation!
[Xperia Tablet Z Original Android Development] Alok Bajaj:
I'm going to change my ROM to CyanogenMod-12.1-20150828-NIGHTLY-pollux. Hope this kernel works on this ROM. :)

I'm so desperate to use this kernel xD
[Xperia Tablet Z Original Android Development] BlackAfghan:
Do not use Cyanogen Recovery to install this kernel!

@Alok Bajaj: I was able to reproduce you problems, and they weren't related to PAC at all. The issue which prevented the TWRP installation has been fixed, please download it again, if you haven't installed it manually, yet!

The issues with boot-loops are caused by an incomplete kernel installation procedure. The way it is installed is very sophisticated, and it seems that it is too complicated to be handled by the very simple and basic CM Recovery..

Do not use Cyanogen Recovery to install this kernel! Install, and run TWRP first! CM Recovery is pretty useless anyway for our purposes..

Sorry for the inconvenience! :)

EDIT: I re-uploaded the kernels, and added a idiot-proof fail-safe. It refuses to be installed with CM Recovery now.. ;)
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Okay cool! I'll try to install the twrp pollux from the same page in the forum. Let's see what happens.. :)
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Hey, it worked. Both the TWRP recovery and the EvoMix kernels are working! Thanks a lot for the fix and for the kernel.. Kernel is working good :) And so is the TWRP :)
[Xperia Tablet Z Original Android Development] Rootk1t:
so installation from CM Recovery is now not possible, right?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Exactly, spend nearly two hours to find a way to detect that this crappy thing is being used.. but still better than noobs spamming about bricked devices.. ;)

Nevertheless, installing my TWRP works fine now with it..
[Xperia Tablet Z Original Android Development] Rootk1t:
Ok. Delete or cross automatic installation instruction from your recovery 1st post.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Hmm? I did? TWRP works with CM Recovery...
[Xperia Tablet Z Original Android Development] Alok Bajaj:
The wifi does not work!

The wifi does not work anymore with EvoMix kernel in PacMan Rom... On CM 12.1 it works fine. But wifi does not turn On on PAC rom CM 12.1!!
[Xperia Tablet Z Original Android Development] BlackAfghan:
Did you use the same zip? When did you download it?
[Xperia Tablet Z Original Android Development] Alok Bajaj:
well i guess it's not the issue with EvoMix kernel.. i guess i did something wrong while flashing. The wifi is now not even working with CyanogenMod 12.1!! :(

I had downloaded the EvoMix kernel and it was working before... i had some issues with my tablet freezing/hang up. So i tried installing Validus ROM which had EvoMix preinstalled. But somehow that ROM doesn't seem to work by flashing with TWRP. I had to flash boot.img via fastboot to make validus rom work.. but it never worked!

after that i tried to install the PAC rom .. the wifi works with just PAC installed but after updating the Evomix kernel the wifi won't turn On. I thought it was some issue with PAC rom. But later i installed the CyanogenMod.. the wifi was working fine... I rebooted to recovery twrp and updated evomix kernel... After the reboot the wifi wasn't working anymore.

What can possibly cause this?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Sounds like a problem with the wifi kernel-module. I rebuilt the kernels, via my automated scripts, since I changed some stuff by hand yesterday and maybe did a mistake...

Please download it again, and re-try it!
[Xperia Tablet Z Original Android Development] Alok Bajaj:
I downloaded and tried... It's not working.
[Xperia Tablet Z Original Android Development] BlackAfghan:
I have only a windy.. can any pollux owner confirm this issue?
[Xperia Tablet Z Original Android Development] Rootk1t:
It does not install from CM recovery as you stated earlier.

So

installation from CM recovery won't work.
[Xperia Tablet Z Original Android Development] Alok Bajaj:
I tried installing from twrp not CM recovery... everything works except for the Wifi. My tablet boots up normally after installation and i've all the under-clocking and over-clocking kernels set... everything else works fine except wifi...
[Xperia Tablet Z Original Android Development] BlackAfghan:
Why not? Did you download it again? ;)

I tested it, and it worked for me...
[Xperia Tablet Z Original Android Development] BlackAfghan:
What is the content of /system/lib/modules?
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Contents of /system/lib/modules

The contents of /system/lib/modules are attached as a screenshot for your reference.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks, the wifi kernel-module has not been installed. I changed some minor config stuff recently, that may could explain that..

So, everybody who experienced this wifi-problem, please download and try again! Sorry for the inconvenience.. :o
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Okay cool it's fixed and working great ;) thanks for the fix and I guess this is probably the best kernel for performance and battery saving. I've been able to tune my tablet very well and those i/o schedulers and governors work great [emoji106]

And i had multi core performance increase from 1487 to 1984 in geekbench ;)

Good for all day normal work but not so good for long time gaming- makes the device very hot! [emoji16]

But still it's awesome!
[Xperia Tablet Z Original Android Development] BlackAfghan:
Great, so you got the 30% performance gain I estimated! :)

Sorry again, for all the hassle and thanks for the testing and reporting!
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Well thanks for bringing it up for tablet z.... ☺
[Xperia Tablet Z Original Android Development] uniextra:
hi i have the WIFI only version, what should i install?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Pollux_windy
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Issue with GPU frequency

Why is the GPU frequency step straight from 320 to 487? You should add the frequency 400MHz. While gaming, at first GPU frequency is set to 487, but then device gets so hot in a minute or two while gaming and the frequency drops to 320MHz which causes significant lag on games like Modern Combat 5 and Modern Combat 4. The CPU remains stable from somewhere around 1.7 GHz to 1.5GHz.

So the question is, can a frequency step be added to GPU like 380 or 420 or maybe 400 itself? :confused:
[Xperia Tablet Z Original Android Development] Alok Bajaj:
After installing this kernel my device would not turn off while charging. If i press shutdown with the device (Pollux) plugged in for charging.. It turns OFF and then turns back ON. Needs a fix!
[Xperia Tablet Z Original Android Development] BlackAfghan:
Why you want to turn it off, while it's charging? I don't think it's a kernel issue, anyway..
[Xperia Tablet Z Original Android Development] BlackAfghan:
Are you sure that the GPU is the issue and not the CPU? How did you measure it?
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Well.. Usually when I want to charge my tablet faster I just switch it off and charge. I'm completely okay if there's no fix for this issue. Just wanted to let you know. I tried flashing my tablet like 10 times. I'm using crDroid now... I've tried this on different ROMs like PAC ROM.. CyanogenMod 12.1 and crDroid.. The kernel works exceptionally well with the crDroid rom. But I had issues with over heating on CM 12.1 (snapshot) and PAC ROM.

I flashed the ROM first and then gapps. Turned off my device and put it into charging it was off. Then I flashed EvoMix kernel and did the same thing, the device would restart when it's off. So I guess it maybe the issue with the kernel..

---------- Post added at 04:07 PM ---------- Previous post was at 03:36 PM ----------

And the thing about GPU is not mainly about heating.. I'm just asking can't we just add another frequency step between 320 and 487MHz? So we can get optimal performance for normal usage and gaming..
[Xperia Tablet Z Original Android Development] cantenna:
Thanks for the kernel but WiFi is not working on Pollux windy. I thought this had been fixed, no?

I have installed a CM 12.1 base rom, Tesla rom.
[Xperia Tablet Z Original Android Development] BlackAfghan:
It should work, since I used my fully automated, and proven script and fixed the bug... ;)

Could be ROM related, can anybody conform that issue with another ROM?

EDIT: Tesla ROM, was built by Alx31, one of the original creators of this kernel. His ROMs are by design not fully compatible with my version, since he prefers to embed all kernel modules, and the CM team uses separate modules.

Anyway, I'm quite sure that it already comes with EvoMix...
[Xperia Tablet Z Original Android Development] cantenna:
I'd like to try your kernel but I'm very pleased with the tesla rom performance I recently installed and don't want to move. Maybe you could add support for Tesla rom? :)
[Xperia Tablet Z Original Android Development] BlackAfghan:
There is not much reason for that, since the original EvoMix kernel and my version are very similar...
[Xperia Tablet Z Original Android Development] cantenna:
There are zero overclock options available on telsa rom, and even better if your kernel could speak to his rom because his rom should have an ear for your kernel more so than others, no?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Please ask Alx31, whether he could include his kernel or use CM, PAC, etc!
[Xperia Tablet Z Original Android Development] cantenna:
I recently flashed back to CM 12.1 and have added this kernel to the rom, great kernel, thank you

I am having problems with init.d though, which is fixed by using universal init.d but universal init.d states the kernel has init.d support yet my init.d scripts don't start unless universal init.d is running,

does this kernel support init.d built in
[Xperia Tablet Z Original Android Development] BlackAfghan:
Yes, I guess it should.. which folder are you using?
[Xperia Tablet Z Original Android Development] cantenna:
/etc/init.d/
[Xperia Tablet Z Original Android Development] BlackAfghan:
I think it should be "/system/etc/init.d" or better "/data/local/userinit.sh"
[Xperia Tablet Z Original Android Development] cantenna:
Oops meant to say/system...

I'll give /data/local a shot, thanks!

Unable to boot the 6th Oct or 7th Oct Cm12.1 nightly

First thanks for a great kernel, works better than stock CM 12.1, I just had 2 questions

1) is there a new kernel release coming out? The last one hasn't been updated in quite sometime and the lp5.1 release has been merged into the CM 12.1 kernel.

2) I am unable to boot on the 03rd, 06th and 7th Oct nightly, the last working release is 30th September, this is both on the stock cm12.1 and evo kernel. Is it just me or are others facing this as well?
[Xperia Tablet Z Original Android Development] BlackAfghan:
1. Yes, unfortunately the EvoMix kernel hasn't been updated for months, and I only fixed the most urgent bugs. This is why I'm working on a completely new one, which is based on the latest CM kernel (which has been updated heavily) and the features of EvoMix. But it will take a couple of days, and I haven't tested it yet.. No begging..

2. Thanks for the info! Are you sure that it isn't working at all?

BTW, any idea for a new name? :)
[Xperia Tablet Z Original Android Development] swayamprakash2001:
1) That's great news, as always you can count on me for testing it out as soon as you have an alpha/beta up :o

2) Its fixed now, it was xposed related, Xposed v75 has fixed this bootloop. Sorry for the confusion.

New names hmmmm, how about BlackEvoMix Kernel or BEM Kernel or Black Kernel or TZ Kernel(TZ = Tablet Z), i'll think of a few more as well.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks, for the name suggestions!

If anyone wants to create a nice new bootlogo, it would be more than welcome! :)

Try it without Xposed or with v75, since there was a fix for recent 5.1.1 versions. There weren't any source changes by CM for two weeks, and the kernel is by design quite resistant against such problems.

I will try it out later by self..
[Xperia Tablet Z Original Android Development] swayamprakash2001:
Bingo, already discovered that xposed was the issue, all in working order now.
[Xperia Tablet Z Original Android Development] scoobyjenkins:
I did the boot logo for Alex, I can do another one if you like? But would be handy to have the name you want! And any other ideas you may want incorporated

*Edit* Here's a design just like the original with a different name, if you'd like me to do a logo, would you want the penguin or something different?

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Nice to know that this kernel is on Active development. I would also love to test this kernel on my Pollux as soon as it is released and let you know :)

BTW i guess "Blackernel" or "Black Kernel" would be a good name as [MENTION=6016906]swayamprakash2001[/MENTION] suggested :) I usually use my Tablet Z for gaming and EvoMIx kernel really helps improve the performance. As I've found that it increases the performance by upto 30%. :))))))
[Xperia Tablet Z Original Android Development] Kurama93:
Can I expect this kernel development for Xperia ZL (Odin)? Please...
[Xperia Tablet Z Original Android Development] cantenna:
Opps, missed posts regarding updates on previous post, sorry :)
[Xperia Tablet Z Original Android Development] cantenna:
Hi BlackAfghan, how are you? All is well :)
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks, yes "Black Kernel" sounds perfect! A simpler boot screen, containing the Sony and the CM logo would be nice!

I could do that, but only after it works fine on the Tablet..

I'm fine, it just turned out to be more time consuming than expected! I finished the kernel on the PC, but than it turned out that it isn't booting... Gonna take some time to fix all the issues!

[MENTION=4728887]scoobyjenkins[/MENTION] might I suggest a better font for the "Black Kernel"... Something along the lines of the font used for material design on Lollipop or Marshmallow
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Some example fonts, let me know what you guys think

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] swayamprakash2001:
[MENTION=4728887]scoobyjenkins[/MENTION] definitely number 1 and 2nd choice number 5, but the final Call should be from [MENTION=411194]BlackAfghan[/MENTION]
[Xperia Tablet Z Original Android Development] scoobyjenkins:
More boot splashes with different fonts
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Can't we get the font as in the title of Transformers movie?
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Maybe a poll to decide!

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Okay cool ?
[Xperia Tablet Z Original Android Development] swayamprakash2001:
[MENTION=4728887]scoobyjenkins[/MENTION] absolutely we should have a poll, btw the bootanimations with the slim font(number 5 in your list) looks amazing, my vote goes to that

and as i've said before even after the poll, final call should rest with [MENTION=411194]BlackAfghan[/MENTION]
[Xperia Tablet Z Original Android Development] phhuang:
This kernel seems got bootloop with the latest nightly?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks! Could you make an all black&white one, with font number 5 (or make a pool for another one) and everything a little bit smaller, please?

PS: I release soon (without beta) :good:
[Xperia Tablet Z Original Android Development] scoobyjenkins:
I'll give that a go!

*edit* Here's another 2 versions, one more to follow in my next post...
[Xperia Tablet Z Original Android Development] scoobyjenkins:
...And another version! Let me know what you think, I can make parts smaller, maybe combine elements of different designs. My favourite is the last all white one without gradients but wanted to give a few options
[Xperia Tablet Z Original Android Development] BlackAfghan:
Mine too.. Thanks! :good:
[Xperia Tablet Z Original Android Development] scoobyjenkins:
No worries, glad you like it!

[Xperia Tablet Z Original Android Development] Komapatient:
Hi,

I just flashed the kernel from OP into my cm-12.1-20151121-NIGHTLY-pollux and I experienced one major issue.

The screen rotation isn't working properly.

When I rotated the tablet the screen did not rotate at all or at least several seconds later.

Flashing the nightly again to get cm-kernel the screen rotation worked smoothly.
[Xperia Tablet Z Original Android Development] BlackAfghan:
There was no change in the relevant code..

But I will release soon the new kernel!
[Xperia Tablet Z Original Android Development] BlackAfghan:
New kernel finished!

Finally and exactly 6 months after my first release, the new kernel can be downloaded and discussed there: http://xdaforums.com/xperia-tablet-...nel-black-kernel-cyanogenmod-12-1-13-t3259121

I tested it for 5 days with the nightly from the 21st November, and it works perfectly..https://download.cyanogenmod.org/get/jenkins/135575/cm-12.1-20151121-NIGHTLY-pollux_windy.zip All reported bugs have been fixed, please try it again with the new one. Thanks for your help! :good:
[Xperia Tablet Z Original Android Development] swayamprakash2001:
Kudos to you, I see no issues at all, perfectly stable and snappy as hell. And [MENTION=4728887]scoobyjenkins[/MENTION] the boot animation is real sweet.
[Xperia Tablet Z Original Android Development] NotALongUsername:
I just installed this kernel along with this ROM: https://xdaforums.com/t/pollux-development-cm13-cyanogenmod-13.2995676/#post-58006383, the ROM works perfectly but when I flashed the kernel the device goes into a bootloop that only shows the "evomix kernel" logo for around 2 seconds before looping. Yes, I've made sure to download the 12.1 cm ROM not 13 cm.

Fastboot cant detect my pollux_windy, I can't get into recovery.

What should I do?

i have a prestigio multipad 7 prime duo 3g

[One (M7) Q&A, Help & Troubleshooting] The Android Manual:
Okay so I already searched and I can't find an answer to my question. I am planning to update my One to Lollipop once I get it back from repair. My brother had an AT&T branded one and he have flashed several ROMs from there. Except, that one broke and I am kind of hesitant to flash ROMs on mine. So as what the title says, will I have any problems if I flash a ROM from the international HTC One thread onto my Verizon HTC One?

Thank you!

[One (M7) Q&A, Help & Troubleshooting] clsA:
Yes and No

that's why their is a separate Verizon one section
[One (M7) Q&A, Help & Troubleshooting] The Android Manual:
Yes I am aware of that. So does that mean I cannot flash neither Viper nor Insert coin on this thing? How sad. One more thing, my One is already sim unlocked.
[One (M7) Q&A, Help & Troubleshooting] clsA:
it's not a matter of being Sim unlocked or not ..the Verizon phone uses a different partition structure

.. did you read their first post ?

And the Insertcoin thread reads
[One (M7) Q&A, Help & Troubleshooting] The Android Manual:
Yeah. I read it a while ago and I also PM'ed the developer of InsertCoin. Thank you for your answer. I'm just really scared of flashing ROMs on this thing now because my brother's AT&T M7 got bricked (or had a hardware problem or whatever) after I flashed a ROM for him and that really traumatized me lol.

Many time people who are trying to call me tell me that they can't dial my number or that they are notified that my number is out of coverage signal area which that can't be the case . Also many times when i'm in the subway or lower floors of shopping centres (-1) for example i'm loosing signal . Althouh i'm very pleased with cm11 on my s2 , should i try to change to another OS , considering the fact that this issue was also present with older nightlies ?

[G4 Q&A, Help & Troubleshooting] StarmanUK:
Just been to an O2 shop in the UK and purchased the G4 - I was curious as to if it was SIM locked to O2. I entered '2945#*xxx#' replaced 'xxx' with the model number of 815 and was presented with window for SIM Unlock Process under each of the options other than Network Lock which invites me to enter a key I was given a message stating that "Your phone is not personalised."

Unfortunately I cannot get the G4 to take a screen shot within the app although holding down the centre button and volume down worked fine under the home screen.

Can I assume then that the O2 supplied model is not network locked?
[G4 Q&A, Help & Troubleshooting] leoni1980:
No, it is network locked. It has no O2 branding though.
[G4 Q&A, Help & Troubleshooting] alanclarkoman:
I also have a G4 from O2 and am having the same problem unlocking it. I tried the live chat with O2 but they could not help me get past the phone not personalised message. They told me to go to one of their shops but not much help as I am in the Middle East for a couple of months. Any suggestions.

I did the same but it's showing "this phone is perma locked... it can't be unlocked".

I have never tried unlocking it. It's a vodafone (Otelo) branded phone and it worked with a O2 card for months. Now the last 3 days, i lose signal every 5 minutes... What is wrong :( went back from cm13 to stock, same problem... I can't call anyone and cannot be called... even if i have signal... only sometimes... thats weird...
