[Q] Yet another noob question - Xperia Arc Q&A, Help & Troubleshooting

hello again,
i hv my se.tweaked mod well just because i didnt read the whole post of doomlord ... now i want something new so i plan to update to ICS and try cm9.0. However, do i need to upgrade the ICS before i can use cm9 mod? and do i need to turn back to stock system and kernel before i use the ICS beta?? thx a lot professionals and experts of xda

No you do not need to go back to stock kernel. Make sure you do a factory reset and wipe cache and dalvik cache after you flashed the cm9 kernel and all should be fine

and dont forget to back up anything important

phone touch screen wont register my touch after rom flash

my first rom was evervolv for droid incredible. i decided to go with magnolia rom.. it all worked up to getting to the lock screen after flashing it. the lock screen wouldnt read my touch.. and i switched back to evervolv. it worked after i did. then i decided to go with Warm Z TwoPointTwo... and it did it again.. i'm getting sick of the same ole same old and i need help.. anyone have suggestions to fix this mess so i can get the roms i want???
Are you saying when you flash a different ROM, the touchscreen is not working, and if so, are you running the kernel that comes with the ROM, or something other before first boot?
Are you fully wiping data/cache/dalvik prior to flashing the other ROMs?
Do you have ample space on your SD card?
make sure you clear data/cache/dalvik and all that jazz.
you can also try flashing a new kernel in recovery, that might do something...
yeah i flashed a different rom to my phone and then it messes up.. the screen doesnt read my touch.. i restored my evervolv for it and it works fine again.. but i dont know how to flash a "kernel" that would work with the rom i want.. doesnt that come with a new custom rom?? and what is dalvik? i just press factory reset or whatever..

Dalvik is under the advanced tab in recovery. I do data, cache, dalvik before flashing a new row. I do cache, dalvik, battery(also under advanced) before flashing kernel. Dl krnel to root of sd card, flash in recovery like rom. I nvr use rom mgr for flashing anymore. Make sure u use sense kernel for sense rom, aosp kernel for aosp roms. Couple of good threads on kernels. Chads kernels work great for my phone, but its preference. Any problems just use the search function on xda, cant find answer then just ask. Good luck.
yes, i am one who likes to flash then flush
This sounds like the same issue you would get with a kernal that is not compatable with a rom. or a theme/mod ment for a different rom. I run evervolv myself and if I try anything else i need to clear/factory reset everything before i flash
i'm very grateful for your guys help. but.. i just ran into that same fix again. i flashed another kernel so i could run the rom i want and it still did it.. so i need to know the kernels that are compatible with roms.. specifically the one i want. (right now its Warm Z TwoPointTwo) but if there is a thread with this info i will try and find it. and also do i flash the kernel for the rom after i flash the rom or do i flash the rom then boot up then go to recovery and apply the kernel.. i'm sorry if i'm sounding too noobish.. i'm learning. very slowly lol
You are flashing Sense kernel with Sense ROM, yes? The kernel is flashed AFTER the ROM install.

[Q] Is it possible to undo a kernel once installed?

I'm using the stock Gingerbread "Leak" rom version 4.12.651.1 that was leaked recently and I played around with it at first. Took several pictures and videos and enjoyed getting back to having Sense on my phone.
I used Kernel Manager Lite to download and install the Netarchy Toastmod-cfs-havs-more-sbc kernel and at now everytime I open up the camera it shows a white screen and I can't take a picture or video anymore.
Is there a why to uninstall or undo this kernel without having to reflash my Evo? I'd like to go back to just the stock kernel i guess. I even tried to use the Kernal Manager Lite to download and install a different Netarchy Toastmod kernel but it wouldn't install it over a previous kernel and when I clicked on the kernel I already have installed it won't give me an option to uninstall it...
Thanks for any help you guys can give me.
Find the stock kernel for that ROM and flash in recovery after wiping cache and dalvik cache.I will try to find stock kernel for that ROM.
Yeah there's no way to undo once u flash a kernel.....may I make a suggestions for ya foe the future.....Ive been doing this for a while......flash the ROM and make a backup once yur all setup...this way u can tinker with the rom and kernels and themes and what not.......and if those tweaks don't work for ya......u got a backup of a fully stock rom......

Thanks guys for the awesome advice!
Reverepats, it's funny you said that because that's the first thing that I thought about after this happened and I'm still kicking myself for not backing it up before flashing the kernel LOL It'll be a lesson learned I guess
Ianmb, that would be AWESOME if someone had this. I'll keep looking for this too but if I have to I guess my only recourse would be to wipe it all and reflash all over again... /sigh
There is a post for a working kernel for that ROM on the second page if the ROM is the stock 4.xxx. Stock kernel 15 I think, can't upload file from my phone?
ianmb, thanks for looking but I can't find any stock kernel #15 out there. not even google can help me =/
So it's possible to reflash a kernel over an already installed kernel? If i find the stock kernel how do I go about installing it? Via recovery?
Forgive me if I'm wrong...but if you just reflashed the rom without wiping, I believe it would install the stock kernel that came with the rom

[Q] [q] need information regarding flashing another rom

i have HTC wildfire. using CyanogenMOD 7 for past 2 months. want to install Splash ROM now. i have some queries & want to be sure before doing anything.
1. do i need to remove CyanogenMOD completely before i install other ROM ?
2. if i unROOT my phone again will i be able to re-ROOT it ?
3. if i just flash another ROM from ClockworkMOD Recovery, will it be installed properly ?
please guide me.
Depends the rom you want to install, some roms require you wipe first, so check the rom installation requirement for any specific one you want to install.

Could not find or just can't be bothered to look? there are plenty of guides on xda and hundreds if not thousands if you search google for a guide on how to flash a Rom!!
Basically if your flashing a gb Rom over a sense Rom a full wipe is needed.
However if the 2 roms are from the same base i.e cm7 and a cm7 rip-off chances are you might get away without wiping anything, do a backup first if it doesn't work without wiping anything, just wipe cache and dalvik cache but leave data alone. If that still doesn't work try again with a full wipe.
As for the guide its pretty simple, backup wipe then install from zip.

ofcourse i do know how to flash a ROM !!
that's how i installed CM7 !!
thanks for answering my 1st query
i would give it a try now.
Q2. If you unroot it you can reroot it again afterwards but I don't see any point unrooting.
Q.3 is basically the same answer as Q.1.

[Q] Kernels and restoring a nandroid backup

After flashing a kernel, they say to do a full wipe (and then reinstall the ROM?).
My question is whether after the wipe, can I restore a nandroid backup? Setting it up from scratch and just the way I like it is quite tedious if I were to do this each time, plus download the apps from the market etc. My arc is my main phone so I don't have the luxury of flashing ROMs and kernels all the time.
Do let me know if that's possible. If not, can you tell me how you guys do it?
My arc is running Stock ICS 4.0.4 with an unlocked bootloader.
I believe you got it all wrong.... you need to do a full wipe before installing a new ROM (to make sure it works properly and nothing is left from the old one).... not a kernel... You can flash kernels as often you want without any wipes. Just dont forget the WIFI-modules (only of needed by ther kernel).

Just think about it, it would be pointles to delete evrething and then restore it back..
P.S.: sh*t I pushed the wrong button and thanked you instead of quote....
yea..there is no point restoring the nand after flashing a kernel...full wipe and fresh installing rom is highly recommended..
Best way is to tryout a kernel..if everything is well and good then better stick to it.
afterall wat do u look in a kernel? OC,UV, good battery life and smooth UI..once you attain all these then stick to it..
btw i have tried many kernels this month without doing a full wipe..i never faced any problem as such..i just uninstall all OC, UV apps just to be safe
Thanks for the replies guys. And an extra thanks to Antochrist for his mistake. LOL!
Another reason for my question was because one of the kernel developers said to do a clean install.
Let's say I flash a kernel with additional wifi modules. Suppose I want to get back to stock kernel and its wifi modules, do I just flash the stock kernel or do I need to do anything extra to fix the wifi?

I think clean install only needed for new rom, not new kernel

Happy new years everyone!
I am pretty new to using custom ROMS and kernels and have made a standard noob mistake
which was forgetting to back up all the original software (ROM, kernel, etc). I realized this quite later
and though I have found the original ROM for my GT-P5110 I seem to have trouble finding the stock Kernel
(the one it had when it left the factory; 4.0.4) I did a search and have found my search-fu to be weak.
Can anyone help me find the stock rom for the GT-P5110 (Galaxy note 2 10.1)?
And one more thing, should I get the Galaxy S3 LTE vs. LG Optimus G vs.your opinion?
(I am in South Korea btw) Is Korean version is any different or any harder to root or to
flash a custom ROM, anyone have any experience?
Many thanks
But I did not get the Right Answer...

Thanks for the info that WIFI modules are included in the kernel and no extra additions need to be made.. I Don't know abt it ..
NOW assuming u now a lot abt Linux/Android could you please answer this for me..
- Does Restoring NANDROID
- Restore 'Stock Kernel' along with 'RIL file', RAMDISK - INIT### n stuff​
Which Hyperion users need to fiddle with..
But kernel and ram disk are stored in the boot partition so does NANDROID back that up too ?
and Can you help me with RIL file related info..
Thanks
NANDroid only backs up ROM. It doesn't back up kernel. Kernel is always flashed externally, it's the same with all Android devices.

[Q] How to uninstall cyanogen mod 9 on Samsung W i8150 ??

Hi, recently I flashed CM9(beta4) to my Samsung W but I found that not everything are working fine to this smart phone. So its a noob Question : How to uninstall this CM9 from my Samsung W??
Did you create a (nandroid) backup copy of your factory installed ROM? If you did, it's as simple as wiping your current ROM and re installing your "stock" ROM.
Sent from my CM10 powered Wonder with Tapatalk 2....it's all good....
You could just flash from odin or there is a thread in the developers section about flashing stock from CWM or you could choose a GB Rom and flash it as we have really good ones (if you want the IOS look try JOY OS Rom).
Press Thanks If I Helped
1st download the rom that u wanna use instead of cm9
2nd wiping the cm9 rom will include going to CWM recovery then wiping system, data, cache and dalvike cache (and its preferred to wipe sdcard too)
3rd ull have to be ready with another rom to flash, if u wanna flash a custom rom then simply flash it using CWM the same as u did with cm9, if u wanna flash the stock rom then use odin (u have the method in another thread)
press thanks if i help you
