Kernel Options with root - Honor 7 Q&A, Help & Troubleshooting

Hi, im currently on an unrooted PLKL01C185B382 with a locked bootloader. Im thinking of rooting my device but i need some advice. I dont want to change the stock rom but wanna try a custom kernel to see change in performance in terms of ram usage and battery life. Which custom kernels can i use with B382.
Secondly, will i lose data on internal storage and memory card if i unlock my bootloader?

[Q] International Atrix Unlock/Root/ROM Steps.. is what i understand correct?

hi, so im actually planning on buying a motorola Atrix me860 here in Taiwan..
after a LOT of reading in these forums, im still not that confident in the steps that i have to go through in order to get a functional unlocked, rooted, custom rom'ed GB Atrix.. so here is what i have learned from my "research"
1. first, i have to unlock the BL by installing IHOP via fastboot (im guessing this is regardless of what stock intl firmware or if it is froyo or gb)
2. after that, i root my device by fastboot using the method in the 2nd post here http://forum.xda-developers.com/showthread.php?t=1138204
3. then, this is where i get a bit lost, in order to fix the ram issue found in unlocked international users, i need to flash the rom 2.3.4 OrangeFR system image, 2.3.4 OrangeFRwebtop image, and the corresponding tegrapart boot image
now, what if i want to install a different custom rom, like the cherry pie or alien, along with faux's kernel, do i just flash them over the Orange FR via CWM, and if so, do i still retain the ram fix? or does it only work with the OrangFR rom?
help will be greatly appreciated

You can install any kernel you want. Check out Faux's thread, he has stock kernels and unified overclocked ones for which you don't need to worry about tegrapart.

oh.. okay..
so do i still need flash the rom 2.3.4 OrangeFR system image, 2.3.4 OrangeFRwebtop image, and the corresponding tegrapart boot image?
or do i just go directly to flashing alien/cherry rom and then faux kernel (which you say will also fix the ram issue)?
Nope you have to flash the faux's kernel first and then you can install quite any rom you want like cherry or alien.
Flashing to the kernel will make it international ect... not the rom (correct me if I'm wrong but I don't think so) so you have to flash the kernel first.
ooohhh, okay okay, i think that's right, thank you
sooo, i have to flash the orange fr stuff, then faux's kernel, then any intl custom rom?
which app did u root with me860. im on HK version

[Q] General ROM Questions

I'm finally jumping off the deep end into the world of flashing my Photon for the first time!
1. Which ROM do you recommend and why?
2. Does unlocking the bootloader still kill 4G?
3. Does the CM Recovery have to be manually installed or can the ROM Manager from the Android Market be used?
4. Common problems/issues to be expected?

1. I've tried both Homebase and Alien and they are both good. Homebase has Shabby's kernal, so it will run a little faster and battery life wont be as good as with Alien.
2. Yes
3. ROM manager is still not supporting the Photon, check out http://forum.xda-developers.com/showthread.php?t=1250697 for step by step instructions on how to do all the flashing and unlocking. These videos helped me out a lot.
4. No problems what so ever, but i'm only speaking for myself.

Thanks for your responses! Once you've flashed a new ROM, I'm assuming you have to flash back to stock to get OTA updates, right?
Which ROM are you currently running?
Which one do you ultimately prefer so far?
What advantages does it give you over running stock?
Does using something like Go Launcher EX on a custom ROM kinda defeat the purpose?

I'm currently running Alien. I like the vanilla gingerbread theme for it but for what i do i cant really tell that much of a difference between this ROM and Homebase. if you want the overclocked cpu, go with homebase. it uses Launcher Pro as an overlay but i'm assuming you can use whichever launcher you prefer. the specs for each rom are listed on their respective thread pages. some advantages are the custom kernel, wifi scan frequency for battery life, no bloatware. Its not that hard to flash ROMs with CWM once you unlock the bootloader and root, so i suggest flashing both, getting used to them, and then seeing which one you like best. i will probably go back to homebase because i like the OC kernel and they have an update that reflects the current software OTA.

Can you see a noticeable speed increase in with the OC kernel?
Does the battery gain from the wifi scan frequency balance out the battery drain from the OC kernel?
Any problems at all with the Homebase ROM other than losing 4G?
.1 Ghz isn't that big of a difference IMO plus the launcher the ROM uses is pretty fast to begin whith. you may lose probably half an hour of battery life from OCing. its a very good ROM and i havent had any problems with it.

[Q] What is kernel and which one is the best?

I'm a complete noob when it comes to tinker my x10. I recently installed DonutHD2.2 on it, it has baseband 2.1.71 and Kernel 2.6.29-000530g5f01537 [email protected] #1....
I've heard alot about doom kernel and the others, however I want to know what's the basic purpose of a custom kernel and which one is the best for my rom. Stable wifi connection is my highest priority xD.
Please help a newbie .

Hi,
kernel is the main system core of every LINUX or UNIX system, even on Android (its something like non.consistent linux...) which controlls the whole hardware available on system - e.g. display,processor, memory, wifi and bt and so on.
As you wrote, your system has stock kernel - standart delivered from SE.
You can use any kernels from XDA for X10i, there are not so much differences between them. The main thing is the CPU governors. Stock kernel doesnt have good CPU governor (called "ondemand"), so it drains battery all the time. Thats the one thing related to kernel. There are also some optimalizations and so on like undervolting, possibility to load external harware support drivers an a lot of other stuff.
But for begginner, you would probably appreciate only the CPU governors, because of battery life.

I hear doom kernel is good, but it has wifi problems, especially with the latest version. Which kernel would you recommend?
Try doomkernel or zKernel, but u must know that some kernels are for locked and some for unlocked bootloader. U have doom for both.

Yes, I am also running DoomKernel
I am using 2.6.29-modFXP-DooMKernel-v04b; could recommend it. And wifi works great (using it often, dont want 3G data plan).
As was told - depends if you are on locked or unlocked bootloader; but locked doesnt matter I have it also for to be completely save

I don't know if I have locked or unlocked bootloader. ^.^
How do I check?
Also if I install any of these custom kernels, would I be able to restore the original SE kernel if needed?
U can check it with s1tool, find it on this thread (step for unlocking bootloader). And yes, u can return ur stock kernel, with flashtool. All info u can find on this thread:

If you havent done bootloader unlock, you have locked bootloader Or test as described above
And yes, if you will install any custom kernel you are still able to load original kernel from SE. In case you will delete locked bootloader image; the stock kernel will load instead. This is on locked bootloader, dont know if this also on locked kernels.
No, DoomKernel doesn't have WiFi problems...I think you said it because once you have DoomKernel installed on your phone, you must flash and adittional file using Flashtool that is called Wifi Module, and everything will be fine again..

Personally I havent used Feralab ROMs, but on other ones I didnt have any problems.
You dont need to backup stock kernel, it cant be erased (only after bootloader unlock).
If you will find any problems, we or I will surely help you
Yap, on locked BL u can't erase stock kernel, u don't need to backup.

Flashing Kernel
I am a total newbie and have rooted my x10 and unlocked its bootloader. But now I want to use custom roms but do not know how to flash a custom kernel. Can you guide to a thread which can show step by step guide on flashing custom kernel???
Any help would be greatly appreciated.

I guess that you can find a complete tutorial on FlashTools topic under the complete FlashTool guide.
Long story short:
1 Install Flashtool and put desired kernel file inside the firmware folder (which is located inside flashtool folder)
2 Connect phone with unknown sources and USB debugging checked on and check if its recognized
3 Click the flash button (the one with the little thunder), select the kernel file
4 Follow FlashTools instructions (it will show up after you select the files and hit ok)
5 ??????
6 Profit

That additional file called WIFI module or WIFI fix must be flashed via Xrecovery, because it's a zip file. With Flashtool you flash just FTF files (FlashTool File).
Doomkernel (V06) are good, Ferakernel also, ThJap th n5-1... This are kernels for Stock based Roms.
For non-Stock based Roms, like CM 7.2 AND CM9.1 based Roms, you must use kernels which are based on that Roms (FXP kernel, Amin kernel...)
That rom that you were flashed (Donut 2.2.9) is one of the best Stock based Rom. You can use Doomkernel v.06 with medium OC (Overclock) 1113 Mhz. First download Doomkernel on PC, and put that file in Flashtool/firmware folder. Than download WIFI module for that kernel and put on SD card of your phone(every kernel have specific wifi module). Flash kernel via Flashtool, when finished, reboot into Xrecovery ( when you power up your phone and blue led lights up, keep pressing Back button on your phone). Choose Install custom zip, than find your downloaded Wifi module and choose to install. After that, choose Reboot option in Xrecovery and enjoy...

So many roms, kernels etc etc

I am relatively new to the whole flashing custom roms scene etc. I have a Xperia Go currently running stock ICS 6.1.1.B.1.54 but I am not happy with the battery life. I have not experience any performance issues running this firmware but the battery drain is starting to get me down. Now, before I flash back to stock GB I would just like to hear other people's experiences with custom roms etc. Can they improve battery life etc because they have a lot of bloatware removed?
Any info greatly appreciated...
Yes custm roms r good than stock..
U should try..
Either its stock based or cm based...
Just see before that is that rom stable or not..

I am back on GB now but can't help thinking my battery life would be better if I could get rid of the all the Sony bloatware. When I open running services it's full of crap!
I recommend you CyanogenMod.
So I can install a custom kernel but I don't necessarily need a custom rom? Sorry for the stupid questions but all I want is better battyer life. I am very happy with the performance of my device
Also, I was wondering if a good alternative for me would just be to root my phone and remove all of the bloatware using titanium backup or similar?

Hi there, a new user here, I have a question regarding kernel. My battery seems to be doing well but recently i've flashed my xperia u with the SXU_TerraRomICS_V1_B54_Final that i got from XDA and my battery indicator is going down pretty fast even in deep sleep. My main consumator is the screen as show in the phone stats. Is this a kernel problem? And if I flash a new kernel will it change my apps, fonts and other?
PS : I like the way my phone is now and I don't want to change anything but to improve my battery life if possible

stock rooted is possible. you either have to restore your stock nandroid backup (i hope you made one) or if you do not have a stock backup and your hboot version is 1.35 or lower you can run ruu, re-unlock your phone via htcdev.
In both cases you have to install SU via twrp to get root on stock rom. but why don't you just a stock like rom + stock kernel? shouldn't be much difference to stock, but i'd say it's easier.
what roms/kernels did you try? you're sure battery drain isn't caused by any of your apps?

Have you tried other ROM-Kernel combinations? I'm on Viper ROM with Elite kernel and getting excellent battery life. I've literally tried every ROM ever made for the HOX+ and settled for the above.
