I try to search the problem in Google and XDA forums and I dont found the solution.
please help me I want the CM9 not the sony ICS rom.

If you didn't Wipe Data/Cache/Dalvik then that's your problem, wipe everything before flashing and it should work, you can backup and restore DATA only on advanced restore at CWM later if you worry to lose your stuff.
if you wiped everything and this still happens to you then I am sorry, I don't know.

its not work

me too, by clearing up cache still doesn't work

Someone on CM9 support please help us

please help me

This might help you
NOTE: CM9 is a bit new and may have a few errors/bugs or may not be stable so that may be your problem, wait until a new RC has been released for CM9
1. Stock your phone to stock firmware
2. Make sure you do a “Wipe data / factory reset” and “Wipe cache partition” before installing a custom ROM
3. Before installing the new ROM make sure your phone fits the requirements needed for that ROM
If it still continues to be that your problem is constantly happening, try using CM7.2

Gin2JellyBean Stuck on Boot

I have installed Gin2JellyBean on my R800i, but it does not seem to work.
I have flashed DooMKerneL, and using CWM, I flashed Gin2JellyBean. I rebooted my system, and it got passed the DooMKerneL, but it always resets itself after a minute of staying on the Gin2JellyBean boot screen.
How can I fix this problem? Thanks in advance

Make sure you format the data, cache, dalvik cache, and system partitions before you ever flash any rom.
I recommend flashing the latest stock ftf firmware for your phone, reboot and reactivate your phone, then flash DooMKernel. Once you've done that, then format all that I mentioned above in the recovery, THEN flash the firmware, then reboot.

Would R800i_4.0.2.A.0.58_Enhanced.ftf be considered "stock"?
(Sorry, I can't post links yet )

Yes. Reflash stock except kernel since you flashed kernel already. Then go to cwm wipe everything and flash Rom.

Nope, still doesn't seem to work. I have tried different roms that are also build off of a Stock GB, but none of the worked, only DiXperia 2 worked, but no WiFi.

[Q] [Arc S] Installing any JB - same problem

I have a problem with the installation of JB. No matter what ROM I install, after boot, when home screen appear, my touch screen does not respond. I've tried a lot of roms and a lot of kernels. I have unlocked BL. In stock rom I have no problems.
What could be causing this? Should I format system before installing rom via recovery or just wipe data, cache and dalvik? When I should flash kernel? Before/after installing rom? I care about CM10. Plz help.
P.S. sorry for my english

I have Neo,and this is how i'm installing it: first wipe everything (data,wipe cache and Dalvik cache),flash the rom,and then flash the kernel.

I've tried to do that way but but not succeed

Certain ROMs require phone-specific patch, make sure you install it!
Other ROMs have different downloads for different phones, make sure to download correct one!
If you install wrong phone ROM, touch dies.

All question threads belong here in Q&A so please post in the correct sections going forward.
Thanks

The problem is caused by the kernal. You MUST have JB kernel to flash any JB ROM. Generally, for each ROM you will find the recommended kernel and the required steps. Do exactly like posted by OP.
As an example, see here: http://forum.xda-developers.com/showthread.php?t=1979829
You can make an idea on the steps to follow.

Ok, so now I have installed Xperia T rom (7.0.A.3.195 v6.0 for ARC/ARC-S). Should I flash V77 baseband, then flash kernel from CM10 FXP150 pack via fastboot, make a wipe (data, cache, dalvik) then install ROM via Recovery, and then install GAPPS and it should work? This is what i'm gonna do, so if I'm wrong please tell me.
EDIT:
(edited in case someone had same problem)
I found the solution:
I had to flash BB 72 and libs, then flash ROM+GAPPS and libs once again, then everything works awesome. (edited in case someone had same problem)

Thank you very much.

[Q]Why do i have problems with installing custom roms

I have locked bootloader, and rooted Arc S. ICS .587. Whenever i try to install custom rom, usually it demands cache and dalvik to be wiped and i do it. But when iinstall it, (i tried 2 roms on with aroma instaler and one without) and on both i got bootloop. Whenever i tried to install mod that also required wiping cache and dalvik i also always got bootloop. When i dont wipe it phone can boot, but features that i wanted to install dont work properly.
I am really intrested in installing custom rom, can anyone help me??? :crying:
Thanx in advance!

Re-read the instructions of whatever you're flashing and keep trying.

Not a lot more to suggest when People make such vague posts.

Usually you should make factory reset and format /system
Have you?

[Q] Need assistance, please

Hello! I am new to the Xda community, and I have a Xperia S. I went throw a lot of Rom threads and read all, even video tutorial and because of that I got confused. Can anyone spare some time (aprox. 10 mins) to answer me some questions, by chatting or here. Please do not make a fool out of me like some other guys around here.
1. if i go into bootloop after flashing CM10, can i restart the phone and go into CWM without flashing again boot.img, and flash the rom again?
2. if i go into bootloop after flashing CM10, do i have to flash the stock rom using flashtool?
3. tell me a simple way to get out of bootloop.
4. flashing the CM10 on my SXS with built number *.2.55 will work?
If I have made anymistakes by posting this here, i would like someone to take it down. Thank you for your time.

I dont have an Xperia yet, but from reading and experience from other phone ...
1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware.
2) if you wiped, try to restart with flashing the firmware again and wiping everything.
3) if nothing working reflash stock, boot stock once to see if it is working without bootloops and then restart from scratch.
4) if also not working .... is it the correct firmware? did you forget something?
There are good instructions for the firmwares, if you do everything as explained, you shouldnt get bootloops. But ... no howto is perfekt.
Its mostly trying as much as possible, till you have the correct way to flash a firmware. Bootloop isnt that bad ...
If you have a way which works for you, keep the steps for later flashing and tell the community what you had to do differently or if you missunderstood some points, even then tell it, because that can make these instructions better.

I would say that it doesnt matter which firmware is on the phone, as long as you unlock the bootloader and the fastboot or flashtool is working.
The custom firmwares use the same methods but might have added recovery for easier flashing later.
You should even be able to downgrade to older firmware with unlocked bootloader and flashing the ftf file.
Its only important to wipe the data, cache and dalvik cache that the firmware is working.

thank you very much but still to solve all of my problems:
You said "1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware."
what do you mean by that? which firmware to reflash CM10? how by restarting the phone? and will i be able to go into CWM without the boot.img?

With different phone and different firmware i had some issues with recovery, specially if i didnt wipe directly after flashing the new firmware without reboot and without reboot into recovery ...
I hope i dont mix anything up. CWM is the recovery (?)
The recovery function is part of the kernel image which is exactly the boot.img.
You can see at the freexperia project page howto install CM10, i cant post links at the moment.
3rd point is flashing the CM kernel (boot.img)
4th point is booting into recovery
From that recovery you can flash the custom rom as described in point 5.
Point 6 is wiping the device, which is neccessary for first custom rom or if you change version (eg. CM9 to CM10) or if you change to a different ROM.
Most bootloops happen if you forget to wipe the device. I am not sure, but most important is dalvik cache, if that one is wiped the next boot takes longer, as it will be rebuilt during boot.
If you get into a bootloop after flashing kernel and custom rom, go into recovery and wipe the device, try rebooting.
If still in bootloop, try to reflash the custom ROM as in point 5 (starting at 4th point) and wipe device after flashing
If it didnt help, try reflashing the kernel and ROM, starting at point 3 and include the wiping the device.
If that didnt help, try to go back to full stock (kernel and rom) and repeat.
But check if you got the correkt ROM for your device.
Play a bit around with the steps, you can even reflash the kernel and leave the rom. I had once a bad situation with bootloops, but they are easy to fix. More important is the part with the kernel, i think there you can brick your device.
But when you follow the instructions you shouldnt have too many problems, just dont jump over a step at the first flashing. But as allways sayd, every custom rom, every kernel flashing can harm your device and you're responsible on your own.
But if you get into problems, write down what you did and you will get help here.
Edit:
"if not possible then reflash the firmware ..." There i had once a problem with a different device. I forgot to wipe after flashing a new version and got into a bootloop. In recovery i couldnt wipe the device fully, something got bugged, but reflashing helped. Reflashed wiped and i could reboot into system. As it was longer time ago i dont remember what exaclty happend, but i think the problem was about forgetting to wipe the device.

Wow Thank you soo much, you lost allot of time explaining this to me, I really appreciate it i understood everything I owe you really
ooh and what do you mean by wipping - all: factory reset, cache and dalvik or just cache?

didnt take too much time
in case of first custom rom, changing custom rom version (e.g. CM9 -> CM10) or changing to a different custom rom: all: factory reset, cache and dalvik
in case of updating (e.g. CM10->CM10): dalvik should be enough, maybe cache and dalvik.
If something not working, do a complete wipe.

As I understand from what I read, you flashed cm10 and are now stuck at boot, did you fastboot the kernel? On my xperia s I always need to fastboot the kernel after flashing a ROM, especially when changing from an ICS to a jb ROM.

No, he has no bootloops, from what i understood he is scared to get into bootloops and doesnt know what to do if it happens.
Hmm, kernel flashing after upgrading from ICS to JB? or all the time?
By kernel flashing you mean the boot.img flashing with fastboot, and its the same file as flashed before?

I've only ever fastboot'd my first kernel, advanced stock kernel. Any others have always been in recovery and never had any issues
Sent from my Android 4.2.2 Xperia S

It seems that you got the wrong Kernel. I'm not sure, of course.
But I had that issue some time ago, and a fix it flashing the right kernel that I found on xda forum. Ohh, dont forget to do the proper wipes.
I hope u solve this as soon as possible.

For some good info on recovering a phone read through the recovery thread in my signature.
Even if you don't have any issues now, you can see what others have done wrong & right.
