Issues with custom kernels

For some odd reason I cannot flahs any custom kernels. Whenever I flash some rom, the included kernel will work just fine. But if I flash another one, like franco or matr1x, I end up in bootloop, or stucks at boot. Anyone else experienceing this behaviour?

You need to make sure you flash a kernel that is built for the version of android you are using.
For example ARHD 2.1.1 is 4.0.2 so you can not use the Matr1x v1.5 kernel because it is built for 4.0.3
Always read the OP before flashing, the info is there
Edit: messed up my version numbers
Sent from a phone that is not running ICS

I have the same problem - no matter what kernel I use or how I try to install it I have yet to find one that will work with a stock version of ICS 4.0.2 on my phone - they always freeze at the boot screen, I don't get any further.

I have indeed checked versions before flashing.

[XXLE4]Issue with custom kernel - disturbing reboots
Hi everyone,
I am facing an huge issue that make me unable to flash any custom kernel without rebooting.
I though it was because brand new XXLE4 cannot support 1k+ frequencies or may be another things than I could not have been imagine because of my poor informatic and linux knowledges but it seems that i am just unable to flash custom kernel. only the original CF-ROOT doing his job but others aren't.
May be because of the SetCPU apps but it is less sure that the origin take his effect from that apps. It is a quit anoying because I would have been set my Scary 120 - 1350 to get an impressive battery life with the brand new UC-Kernel but seems to be a mirage for me.
I had got some custom roms but I can't just use them because I want an real free-bugs ROM an official release are the only one option for me and my usual usage.
Thanks in advance for the help provided and I apologies for my bad english.

maybe EXT format?

4.0.2? I believe no custom kernels support 4.0.2 anymore. Updated/latest versions of said custom kernels at least. I think franco has a 4.0.4 version of his though i'm sure very few people are on 4.0.4, 4.0.2 is just a thing of the past.

64 million dollar question, should I custom ROM?

Hi
As title says I am toying with the idea of updating my ROM from stock 4.1.1
Although I am happy with its overall performance I would like to know from other people what they felt were the main difference when they changed ROMs
I would love to get rid of all the bloatware and have the new camera app with 4.2
also...read somewhere that 4.2 will be available OTA in the new year but what the hell, people root out of the box so it can't be all that bad
All advice welcome thank you for your time
Cheers
Lee

If all you want to do is remove bloatware, all you need to do is root. You can install some of the 4.2 apps without rooting either.

You don't need to use a Custom rom really.
I got my Note 2 since yesterday and I'm really happy with stock performance (and I was coming from a SGS3).
I just powered it with root and XposedFramework with call recording and multiwindow modules.
I don't know only few devs are doing their mods with xposedframework...
Enviado desde mi GT-N7100 usando Tapatalk 2

If you want to tweak and customise it then go for a custom ROM.
Otherwise, if you just want to remove pre-installed apps then just root it and stay on stock as D3 suggested.

Ok so rooting is a must, would I still get updates OTA if I am rooted? maybe for now I can just uninstall bloatware and install the camera app until 4.2 is released
Going to give this a whirl

I went that way with my Note I, and was so addicted to it that I didn't rest until I bricked it, of course it was entirely my fault alone but will never take that root again.
So my 64 million dollar advice is no, I will most patiently wait for the stock ROM.

I dunno about OTA. I rooted and flashed custom within about 2hrs of getting my Note 2
Put it this way though...any updates, fixes or features included in new official firmware will always be included in the latest stock ROMs, often even before the official stock appears as many XDA devs have industry insiders who often leak f/w early.
Easiest way to root and install a custom recovery:

All soft-bricks are fixable... don't let it put you off enjoying the vast array of awesome custom ROMs available for Note 2. Just be sure to always have a back-up handy, and to always read the instructions as many times as it takes for them to be clear in your mind :good:

If you have to ask then no.

You must be flashing the wrong ROMs
I've been doing this a long time too, on lots of different phones and rarely have any bugs or frustrations, certaininly nothing that isn't usually A/ apparent on stock f/w too or B/ fixed within hours/days by the ROM devs. I wouldn't say I'm a flashaholic though, I tend to find a ROM that works well then use it for a few weeks with the odd kernel swap until the next major release, usually a new base, then I'll monitor the threads for a few days to see what issues others are having and see if it's worth my while updating. I guess that's half the fun for me though and I understand some people simplay can't be bothered with it. Each to their own :good:
The good thing about Note 2 is it has good stock and cutom ROMs so you're going to have a good experience either way

I'd echo citizenlees comments. The stock rom is pretty good.
I'm a relative new comer, and I'm in the process of mixing up ROMS And kernels. And I have to say it's been fun trying new things and seeing how they work for you. My battery life now is mega! And that's only from tinkering.
Make sure your back up is solid depending on which recovery version you use.
I've had to use the recovery method when things have gone pear shaped, but all good now.
Have fun and explore in small steps.

you need to have root to enjoy your android phone to full...for ex: to include all apps in multiview, etc..........but when you have rooted the note2, there is no way you get OTA updates...they are also far and few..you need to update by flashing the official new firmware using odin, when it is made available, usually 2-3 months later than the leak....and you would again lose root...so you again have to root......(unlike my asus tablet, where i can restore root without problem and i get OTA updates despite being rooted..and i am using stock rom on it...asus is fast on updates and fixes)
so think about it, ...you may as well flash custom roms (most are close to stock on the note2 ...just debloated, rooted with all tweaks and mods pre-installed) and enjoy all tweaks and updates earlier.
just read instructions carefully, no problems

The stock firmware is wonderful. I myself got my note yesterday and I am planning to just root and debloat it. I would advise the same.
Sent from my GT-N7100 using xda app-developers app

i'm more than satisfied with fully stock ROM ( with disabling bloatwares )
just playing with kernels

Im using it stock (4.1.2 official) + root + cwm (to flash some mods for odex roms...) .. And i enjoy it.. THe only thing i miss are those mods for notification toggles, as i cant get them to work on odexed 4.1.2...
Rest is totally fine...
And for the OTA. you dont need to wait for ota.. Just follow xda and, when next official version comes out (4.2) just flash it via odin

If quality don't matter, 4.2 camera isn't close to Samsung's firmware camera. Just something to consider.

Device belong to us..not samsung anymore. Unlease the power!

Update....
hence forth with cm10.1 and gapps-jb was a pleasant experience I have to say.
on boot chose not to do a full synch with gmail, sweet that it re-downloads all ur apps but on this occasion thought best not to
camera didnt have sphere!! so i flash it with 4camnex2 so now I have 2 camera icons in my app draw one that has no sphere and one that fails to load!! hmm
also keyboard doesnt have any number across the top, I was sooo used to this previous now its just a bind having to press 123 button
on the whole I am still glad I upgraded to 4.2
am I right that I could re-flash with an official ROM and revert back to OTA updates?
Any advice on tweaks wit this would be most welcome

Kernels and WiFi

Why do some kernels kill WiFi when flashed. Or is it just a mobile Odin thing
I have also tried to replace the kernel and rezip same issue
Sent from my SPH-L710 using xda app-developers app

Kernels control the hardware functionality. They specify higher-level functions so that the software (Android OS) can properly interact with the hardware. The kernel is what contains the drivers and such that you need for your different radios to work (mobile network [LTE or 3G] and wifi), as well as things like power management and proper boot/shutdown sequences. If its not implemented in the kernel, theres no way any programs can access the higher level functions to get the wifi going, or to get 4G going.
This is also why it's difficult for some devices to get working 4G on android versions past what is officially supported because the 4G drivers have to be written from scratch into the kernel, and they change from version to version. Now its not impossible, but very difficult
Hope that answers your question :thumbup:

Knowing this, does that mean TW kernels are better for writing things like 4G? I don't know how to explain my question, I guess I'm asking if TW kernels are more 'compatible' since they're just stock modifications.

OK the reason I'm asking is because of my port of pure aosp the stock CM kernel will not do WiFi but any other kernel will Lean BMS KT
Why work with one ROM but not another.

No, what I mean is that once its officially released (for this phone it would be Touchwiz), then that can be incorporated into aosp kernels made for that official version for a specific phone. Both (theoretically) run it just as well, theres no compatibility issues in favor or either. But of course, since TW kernels have been engineered for this phone while AOSP has not, AOSP kernels would require a little more hacking to get it to work, hence possibly degrading the quality of 4G or other radios

My guess would be that the paths for different things arent what its expecting, you would have to split the boot.img and diff the files to find out for sure though

Wifi broken
So, on a Sprint Galaxy S3, after rooting first with the unified toolkit and finding that my wifi no longer works, I went back to the stock version and found I still had no wifi. Figuring that it's better to be rooted so I can tweak things, I rerooted using QBKing's method (much easier, by the way). Wifi is still broken. Is there not a fix for this yet?
I've got:
Model#
SPH-L710
Android Version:
4.1.1
Baseband Version:
L710VPBLJ7
Kernel version:
3.0.31-CL616748
[email protected] #1
SMP PREEMPT Sat Dec 1 23:25:55 KST 2012
Build#:
JRO03L.L710VPBLJ7
Hardware Version:
L710.14
Because I'm a quiet one, I'm not allowed to comment in the forum that originally started this and I don't have 10 posts yet. So, here I am - sort of on topic and sort of off topic. But the bottom line is, I need to fix wifi since I'm *always* in roaming and connect to the world through my wifi.
So.
Ideas?? Please.
Thanks!

When you rooted, did you install a custom recovery (CWM or TWRP)? Turn off your phone and boot into recovery and see if it's either of those.
You're currently on an out-of-date system. I don't think that's why you don't have Wifi, but I thik it'd be best if you try the latest and greatest.
If you do have a custom recovery, you can flash the stock rooted rom by Freeza. If you don't have a custom recovery, you'd have to re-root and make sure to follow the instructions (including pulling the battery).
If you need help with how to flash a Rom in a custom Recovery, I wrote this up for a thread earlier.
Hope you get your wifi working.

I guess I'm not sure how to answer your questions. I do have ClockWorkMod (that is what CWM means, right?) on right now, yes.
That page you recommended is over-the-top. There's so many choices, I don't know which one to make! I think I want Odex, just because I'm not a developer at this stage. Because I'm starting out with CWM, do I want this one or that one?

MD5: 5C24F1174C40E9B878C7D9BEA75DBFAF
Or am I just completely off target?
Thanks for replying and I hope my wifi gets fixed, too.

Yes, CWM is ClockWorkMod.
I'd recommend DeOdex Rom, because if it doesn't work, you can still flash mods onto it that might help you out (without reflashing a whole new Rom). If you install the Odex version, you wouldn't be able to flash most mods out there.
I haven't messed around with the "Leaked" build, so I'd personally recommend the latest official, which is the MB1. The link you should be looking for is:
DeOdex:
Sprint Touchwiz Jelly Bean 4.1.2 L710VPBMB1 | Mirror | Mirror 2 (Not yet active)
MD5: 37E1CCCB3A30959C64DF238D0BD2B23C
If you download this file and install it per my previous instructions (that I linked to, make sure to do a Nandroid Backup and to wipe the /system in CWM), Wi-Fi should be working. If it doesn't I might have another thing I'd want you to try, but I'm fairly certain this will do the trick.

THAT worked beautifully. I guess I just needed jellybean. lol. So, I'm rooted, on the latest and greatest, AND I have Wifi! Yae!
Thanks so much for your help!

Unable to Flash Custom Rom

About a month ago I had a Samsung Galaxy SIII Model # SPH-L710. I had little to no problem flashing a custom rom onto it by rooting the phone, installing TWRP, and installing the zip file from the Cyanogenmod Website. Very simple and painless. That phone however ended up breaking so I had to get a new one of the exact same model.
Now, I've been having a world of trouble with this one. To start when I tried to flash the ZIP file in TWRP, it would give me a status 7 error, I was able to remove that by updating my md4 baseband using the md4 baseband flashable zip which was mentioned in this thread http://forum.xda-developers.com/showthread.php?t=2303308
Once I did that the status 7 error went away, but now it's saying it cannot find the md5 file regardless of what custom rom I'm trying to install, it does say the install was successful, but all the log shows is that it couldn't find md5 file and then Successfully created partition tables and when rebooting the phone it gets stuck on the splash screen (though it IS the splash screen of the custom rom I was trying to install).
When trying to use CWM it says that it cannot even mount the SD card to install and ZIP file so I could not go very far with it and besides, the last time I did this I used TWRP just fine.
Any insight would be great.
Thank you!

Also being a new device you will only be able to flash TW roms until there is a work around for the current block...which i do believe devs are working on as we speak. Good Luck.

Tried all 4 provided .imgs without no success and tried the odin versions which gave me the same results. Seems like this has to do with it just being a new phone. I am able to gain root access, mount storage devices in twrp (but not CWM) but just can't seem to install CM nightly or stable. Just says its updating partition settings and thats it. Also says the same thing with AOKP roms.

CM and AOKP are all aosp style roms. They at this time will not work on a new S3.
Like stated only TouchWiz roms will work. There are literally dozens of them. Googling won't help as much as going directly to the forum for Sprint S3 d2spr development section here on XDA. Do not attempt to flash any rom TW or AOSP if you did not get it from that specific section on XDA you risk turning your device into a 600$ paperweight.
Have a great day!

I hope someone can help me. I have the boost mobile version of the galaxy s3 L710 and I was told I can only use sprint custom roms to flash on my device but when I do they don't seen to work properly. Data ect.

[SOLVED] Sprint galaxy s3 gets stuck at boot unless using stock Rom

So I've done some searching in the forum (on phone) and wondered if anyone else is having an issue flashing roms other than stock rooted.
I've tried all kinds of other roms cm, miui, liquid smooth, et cetera, and they all get stuck at boot. This is a new thing because I've run all these roms in the past.
I'm on moar 6.1 and it's a great Rom, but I'd like the option to change roms at some point...

You are naming AOSP roms. If you have a newest S3, please try with an updated version. Start with SlimBean build 2( exactly that one) because it's confirmed to work with newest models.
