Kernel explain - G4 Q&A, Help & Troubleshooting

My question is
Can i install kernel when ive got working phone like right now?? Or i have reflash all thing again?? What woukd happen if i will flash kernel right now ?? And just only kernel. And what adv gives me to install custom kernel pls explain

Hi,
Based on your post, I don't have enough information to say one way or the other. To flash another kernel you need to have an unlocked bootloader and TWRP installed. If you meet both of these conditions, then yes you can install a different kernel regardless of the fact that you aren't installing a ROM and Kernel at the same time. As always, make sure you take back ups before you proceed.
The next step is working out with kernel. You can not install a kernel designed for a stock based ROM on CM13 or vice versus.
Regards,
Ravi

Flashing a kernal is simple. Just head into recovery and flash. You'll keep all your data and everything would look like the same like before.

[Q] Help with Xperia Play - Flash?

Hello! I'm a noob here for now, but I hope I can change that.
I will own an Xperia Play soon.
(EDIT)If it helps: It will be an Xperia Play in White. I read that it may be R800i... don't know what's meant and what differences are. (Because there is R800x, R800a...)
I found out, that you can install ROMS, and do a lots of stuffs (well, it's Sony) if you flash it or something...
My question:
After searching the Board for how to flash it, i realized that I don't know so much about the Xperia Play and where I should begin.
I ask you, how do I flash it, what about the ROMs and what should I know about it, I mean, what does this flashing give to me? (I know about the risks since I'm hacking and flashing PlayStation Consoles...) Is there more things I can do then with it?
Thank you in advance! Any help is good for me.
Greetings,
HelpmeImTired.
U can flash custom kernel and custom rom to PLAY
For kernel, it normally will give u more freedom to play with you device cpu speed and some tweaks related to it (like i/o and else) some kernel also bring support to more advanced setup option for your device
To flash custom kernel u will need unlocked bootloader.
As custom rom, i believe u will understand what it can do by browse through development section..
Normally we flash the rom via CWM recovery (which normally come together with custom kernel)

If I understand right, I have found in this Wiki (where I looked for some Answers) a Link to a bootloader unlocker (incl. Guide) and I should follow all the steps. Is it important to know, which version I have?

What about this CWM recovery? And where do I get this custom kernel?
I know, I'm noob. Hope I get some more answers. I want to "unlock" my phone (which I received today (AWESOME HAPPY ) ) as soon as possible ^^
I saw awesome THEMES for that phone and want to apply them.
Getting the Custom Kernel to my phone will give me access to install games the so called illegal way? You may know what I mean... after getting the software just installing it and the phone doesn't .. you know what I mean.
Thank you!

It's not unusual for that entry in the build.prop to be blank, and shouldn't cause issues. I think the default there should be '11 11', though having it blank should be fine (pretty certain).
> Working perfect on stock based rom
Which roms are you flashing that are giving you problems? Many of the e980 roms are bugged out in various ways, maybe it's just a quirk of the one(s) you flashed? I had a similar problem recently, wifi just would *not* stay enabled, would not behave. I don't remember which rom it was though; I flash too much.
You've flashed the Kitkat 20g modem, yes? If all else flails, you could always flash back to Kitkat stock and start over, that's guaranteed to tell you whether its a hardware or software problem (if it persists after that: hardward, got to be).

Booyah: E980 20g Kitkat TOT.
Also, with Lollipop roms, I don't think any of them are totally stable or functionally 100% yet, so that's not a place to go if you want stuff to work. There's plenty of nice Kitkat roms like PAC-rom or Carbon-Rom is you want stability and want for your phone to work fully (but thats no fun! ).

Oh, no, you misunderstood: you don't use the CWM, you only install it and then quickly install *over* it with one of Freegee's recoveries. Never use the Sphinx CWM, as you'll get errors when you go to flash roms. You only insatll the Sphinx CWM so that Freegee will recognize your device and function, it's only a stepping stone to Freegee, not a recovery you should use on its own.
And, in light of recent developments on the TWRP 2.8 front, I'd say give that a try instead. It mounts your external SD just fine. THe only things I've flashed with it are BlissPop builds and Gapps, but all without an issue yet. Go for the one with the Play theme and enjoy its gorgeous colors.
Thanks buddy.. Freegee recognized my device and installed cwm succesfully

Welcome to the VZN M7 Forums! I have successfully used sunshine to unlock my BL on Android 4.4.3. I did a lot of research on which recovery I wanted to use. I had in the past on my Motorola RAZR and Droid4. I tried CWM 1st. Then found out that I had a possibility of loosing root. Out with CWM and in with TWRP. I made backups of my stock rooted phone. Then I installed a deodexed (debloated) KitKat ROM. I got a noticeable performance response. Less lag. I then looked into kernels. I chose ElementalX for the sheer power control it gives me. But, the ROM I was using wasn't supporting the changes I was making. Solution? I decided to do a full format and fresh install for ViperROM and ElementalX kernel. Also, just bought the EX kernel app.
Current setup:
Current TWRP Recovery
EX Kernel 18.0
ViperROM 7.0.2
Woo that ex kernel looks nice. Do you know a ruu I could use to update my firmware to use those an possibly a link to the current twrp? I can't wait to use dt2w.

I only recommend going to either 4.4.3 or 4.4.4 since a lot of the M7 owners who have updated to Lollipop are experiencing issues of some sort.

I also advise purchasing the EX Kernel App manager if you really like the Kernel features. This way you dont have to reboot everytime you want to change a parameter

Yes i mean trickster mod. Actually i have a very little knowledge about kernels so it would be better for you to ask someone else and as for the RUU , I would recommend the lollipop RUU because it has the latest firmware otherwise you can use that 4.4.3. You can even flash the firmware only zip the first link in my previous post.
Uh well i installed the 4.4.3 ruu and flashed twrp then tried to install the ex kernel but it boot loops am i doing something wrong?

Yes for using that ex kernel you have to update to lollipop version it wont work on 4.4.3 its in the description of that kernel. If you want to use 4.4.3 only try to use some other kernel.

Yup i'm on 6.22.605.3 i used the official ota to update just downloaded the two zip files and flashed them in stock recovery. I'm noticing significant lag and hanging problem since i updated to lollipop. I'm also thinking to downgrade to 4.4.3 using the S-ON RUU i like to use pure stock but i have s-off and bootloader unlocked so that i can downgrade anytime. Remeber one thing never S-On your device a number of people did that and now they have bricked phone. Good luck happy flashing :good:
Thanks for the info. Gana try downgrading after I drink a gallon of coffee.

Try to erase cahce and then reboot again if that doesn't work then either problem is with the sense version or somthing else.
Looks like i need to flash a insecure kernel first then flash ex kernel. Also you know where to get the most recent version of ex kernel for kk?

You can't flash the GSM version of ElementalX on a Verizon m7.
You can look for latest ported version in Verizon m7 original development section.
I forget what the last version posted was, as I port and modify my own...but I'm pretty sure Kitkat is there.

Installing custom ROM on D855

Hi,
Now I'm running stock v30c rooted by king root and hacer permissivo(one of the method available on xda). I've flashed twrp by autorec.
My question is:
Should I know something before flashing custom rom? I read somewhere that some of roms need v21c modem, and other have no information about it. But I'm not sure if I should flashing this.
Basically I'm thinking right now about custom stock based roms.
One more, I see that some roms supporting CTT(AFAIK it's something about keep the phone cooled, am I right?). Is it supported by every kernel? Including stock one?
I'm coming from G2 and there were quite easier with everything .
Thanks for every answer.

If you are planning to flash stock based roms you don't need to do anything else including flashing the baseband. Only aosp based roms need 21C baseband. So if you flash a aosp based rom remember to flash 21C along with it.
The ctt mod works on most kernels including stock but you don't necessarily need to use it until when you feel uncomfortable temperature.

No sim with lineage based roms

Hi, i need some advice about this problem, bcz i searched that a lot but i cdnt find anu solution. Any Lineage based roms, like Viperos, Strelka, Ressurection Remix, Aokp rom etc (Any 7.x.x too i guess) doesnt work well on my n7100. Im flashing them and they are booting fine too, But when the screen came on, they says no sim, when i checked about device i dont see any info about modem. But imei is not erasing. Boot loader mj5, modem nd3 (i just changed it mj7 modem but still same) . When i flash stock rom or Hyper rom or any 4.x.x based rom works fine. I cdnt find any solution bcz i tried everything. Anyone can give me an idea about this ? bcz i stuck with 4.4.x roms. Thanks..
Is the phone running the latest by bootloader and modem? Some custom ROMs require a phone that is running the latest version of both.

Yes , found latest ones in here and flashed some time ago.
Did you update the bootloader and modem by flashing the latest stock rom or just the bootloader and modem? Not sure if this would make a difference.

I tried both way. Stock rom and 4.4.x based custom roms works fine. They were working fine with older modem and bootloader too. I tried to flash lineage based custom roms on working stock rom and custom 4.4.x too, w/o wipe. They did same thing, everything works fine just no sim silly right ?
Very strange that the sim is not detected. I don't have a note 2 to try out Lineage.
Did you post your question in the the ROM's thread in the Development Forum? Perhaps someone there could offer some more advice.

Yep its strange, i guess the real problem is those roms doesnt see what modem i have in device, bcz they are not showing that in about device. Thanks anyway, at least you tried to give some ideas
