[Help] Custom ROM

I updated my Arc S with the official ICS update from sony however the lag and other issues were driving me mad so i decided to root my phone.
The next obvious step seemed to be installing a custom ROM so i installed clockwork mod and made a back up, everything great so far.
I made a back-up and wiped my phone, went to install the free xperia CM9 ROM and thats when everything went pear shaped.
The ROM didn't install, i wiped my phone again but got the same distressing fail.
Thinking there was possibly a fault with the zip i re-downloaded the ROM and found an alternative (one of the arcronium ones i think) and put those on my SD, all seemed to be well and good, i had a backup and Clockwork Mod what could possibly go wrong?
Well when i tried to boot my phone in recovery all i get is a boot loop! :crying:
The only thing i could do was to use flashtools and flash a ROM to my beloved Arc S
I tried this exact process a few times but suffered the same fate, please can someone tell me what I'm doing wrong? or could i apply a custom ROM using flashtools?
Where I'm currently at:
Model number: LT18i
Android version: 4.0.3
Baseband: 8x55A-AAABQOAZM-203028G-70
Kernel Version: 2.6.32.9-perf [email protected] #1
Build Number: 4.1.A.0.562
Where I would like to be in an ideal world:
Fully working Arc S running Cynogen Mod 9 :victory:
Any help achieving this would be greatly appreciated!

FXP ROM function best on FXP Kernels... Try flashing one of their Kernels and reinstalling the ROM.

Bootloader open?
And for CM u need a fxp kernel, but u cant use it with arconium, there u need trinity or arc-knight kernel

Make sure to do a "Wipe data / factory reset" and "Wipe cache partition" when going from stock or from another custom ROM

I have no idea if my bootloader is open or not, how do i tell?
I found this link to the FXP CM 9.0 but i have no idea what anything is.
http://forum.xda-developers.com/showthread.php?t=1356685
I'm guesing "CM9.0 RC1 FXP127" is a kernel? and if so how do i flash it and what do i do next?
Thanks for the replies, I'll be getting my Arc fixed in no time

Did you follow any instructions from sony to unlock bootloader?

No, it's a ROM. You need to read things carefully before just going and flashing this or flashing that. Flash a stock ROM with the Flashtool and start over.

Dude, First thing you gotta do is unlock your boot loader. Google around you will find it. To unlock the boot loader as well as to flash a custom kernel you need something called fastboot. There is a video in youtube on how to use fastboot and flash custom kernel and that user has provided the download link as well go and search. After unlocking boot loader install CWM (either with auto installer or by flashing a custom kernel with CWM) After doing that flash the FXP127 zip booting in to CWM. The FXP127 zip contains the FXP kernel as well so don't worry when you flash that the kernel gets changed as well. Still can't figure it out. I suggest you keep away from flashing roms Just kidding.

I'm on a stock ROM at the moment that i flashed so i'll just follow some instructions and unlock my bootloader first.
Where can i the latest FXP kernel?
Again Cheers guys

You can find CM9 kernel in zip that you just downloaded. Open it an Extract "boot.img" file. That is the kernel. Flash that first, go to recovery, wipe all data, wipe dalviks chcae, format /system and then chose "install .zip from SD card" and select FXPCM9.zip (or whatever it is named) and it will install you CM9. Don't forget on Gapps.

excellent i unlocked my bootloader and i've got the kernel and rom i want, just one last thing, whats the baseband and when do i flash it (if i have to flash it at all)?
Unfortunately i forgot i uninstalled the stock sony launcher and when unlocking the bootloader it wiped launcher pro so my phones pretty useless as it stands so the quicker i can get a new rom on the better!
Many thanks again, I'm slowly getting there

All done
Cheers for the help everyone!

baseband controls radio communications like communications with cell towers

I did not flash any baseband and it works

[Q] arc doesn't boot

Dear masters,
After 20 hours of reading and trying new things to me, I thought I finally knew what to do to get a custom ROM on my XPERIA Arc with stock 4.0.2.A.62 firmware. .62 seemed to be a pain in the ass, because this version doesn't want to get rooted. So I unlocked my bootloader and then flashed 4.0.2.A.42 on it. Everything on my phone was working fine.
Now I wanted to get a custom ICS ROM on my phone so I decided to go for Xperia Ice Cream Pureness V13. I downloaded the ROM and the patch for the arc and succesfully installed it with CWM recovery.
I did this by going into fastbootmode, flashed this kernel by doing "fastboot flash boot boot_ARC.img", because I needed a stock kernel, so I thought it would be better to get an advanced stock kernel. Then I did "fastboot boot recoveryARC.img" and my phone booted into CWM recovery. I had no errors whatsoever during the installation of the ROM and the patch. Using this recoveryARC.img file is my only way, because via the ROM manager app, I don't get into recovery.
When I tried to reboot, I just got another boot logo appearing, but just stays there and won't boot. See the image in the attachment.
So now I'm here with a not working phone and my noobyness.
Please help, thanks in advance,
Ruben

You say that you have installed advanced stock kernel.
Is it compatible with your ROM??
Edit...
Readed a little. Any stockbased kernel is suppoused to work.
Try with the latest stock kernel.
He says to let it be for a hour.
If anything wont help, revert to all stock.

Yea, so it's stockbased.
Anyways, I just kept on trying things and also tried a different ROM and now Jellybean Sandwich 7.3 just WORKS.
Still got no idea what caused the stuck booting screen.
To me, all these files, kernel, rom, flash, root, etc, etc complicates the whole thing and it doesn't make sense to me anymore what works with what etc... LOL. Anyways, it works now, thanks for caring

When I go to 'About Phone' now, I see the kernel is 2.6.32.9-perf / [email protected] #1.
Seems like this is the original kernel, so the kernel never flashed? Strange...
Everything works fine...

No longer booting
So i saw this thread and its relevant to me. Figured i would start here.
Using CWM i loaded Iced bean ROM to my phone.. in my excitement i forgot to flash the arcknight kernal.. Now my phone simply boots to Sony Ericcson boot screen. No further..
on top of that i cannot seem to load into fastboot. When i try the steps from this thread.. http://forum.xda-developers.com/showthread.php?t=1034087 i cant get my fastboot to work.. no blue LED.
Have i ruined my phone?

I don't know it will work or not,but man, you can try ...
1: Using flash tool, put your Arc into Fastboot mode.
2: reflash boot_ARC.img
3: try some roms such as Ultimate HD 2.0 (recommended) , Jelly SandWich......
i hope it will be useful for you.

My problem is i cant seem to get into fastboot mode. I followed the steps to unlock bootloader but i cant get into fastboot. never get the blue LED.

@OP
The problem is, you 'jumped' from GB to ICS straight away with cwm flash. When changing OS, be sure to flash the new OS ftf first, then flash the kernel, then flash the ROM thru cwm at last. It's good to know though that now your phone is working again.

Hello again guys, I installed LuPuS v8 JB Kernel on my phone (I had 4.0.2.A.0.58 Enhanced Firmware (Gingerbread) installed) then I went to CWM to flash the .zip with the wifi modules and G.Apps but when I rebooted I got a bootloop. what I have to do to correctly install it? Please guide me since I'm kinda newbie to this of unlocked bootloaders and kernels :/ (I'm trying to install PACman rom and followed the FAQ guide but...)
EDIT: Forgot to add, my PLAY is an r800a(i) GSM btw, I have to take off the SDcard to enter to the Kernel menu, idk if this is normal

After you flash the Rom reboot the phone and just let it fully boot. After that you can go back to CWM and flash the WiFi modules and other add-ons

You need to boot into the kernel's recovery and set it to jb mode or ics depending on your rom. Then make sure your rom and gapps don't exceed the system partition size, which it most likely did if you flashed the full gapps package as well.
The default recovery for the lupus jb kernel is TWRP, if you load into another CWM recovery it most likely did not flash to the correct partition arrangement that lupus kernel use therefore the rom can't boot.

These are the steps I did
1.- Flash the 4.0.2.A.0.58 Enhanced (2.3.4 firmware)
2.- Flash the LuPuSv8 JB Kernel via flashtools
3.- Take out the SDcard (I can't access to kernel menu without taking it out)
4.- Access Kernel menu then go into recovery mode
5.- Wipe data/cache/davlik
6.- Flash p.a.c.man jb
7.- Reboot
And then it bootloops and stays like that (i left it alone and it stayed like that for about 20 or 30 minutes)
I also wiped data/cache and davlik after flashing the rom, but got the same results, maybe I need a vendor unlocked firmware like in Turbo Kernel? I will try that...
Edit: Flashed the vendor unlocked firmware then wiped cache and data then installed the PACman rom but got bootloop again, maybe I should try with another kernel...

[Q] Cant install custom rom on X play R800i

Hi,
Hopefully someone can help. First off, when I try to unlock bootloader, It says it's unlocked. I can root my phone through flashtools with no problems also. I tried the ICS and JB roms with a lupus kernel as described on Youtube. I follows the instructions to a T and when I install the rom from the sd card, it never installs,...well it does install as in it goes through the installation procedure. It just reboots to the recovery mode after the installion instead of the rom etc to ( the lupus or doomlord recov mode depending on the rom). I have tried different roms and downgraded to ginger 2.3.2 ( I am currently on 2.3.4) but there is no change. Any help would be great thanks ...

Hi,
I bought the phone second hand. When I tried to unlock bootloader, it says its unlocked already...must have been done by previous owner

Did you follow all the instructions for instlling a ROM???
1. Factory reset
2. Format-wipe /cache (it says formattting /cache when doing factory reset, but do it anyway)
3. Format /system (its on mounts and storage menu)
4. Wipe dalvik cache (its on advanced menu)
5. Fix battery/wipe battery stats. This depends on the recovery, but is the same thing...
6. Fix permissions. I think this is what you are doing wrong of missed out.
Btw, if you can enter fastboot mode and flash custom kernels, you have unolocked bootloader

Xperia Play boot loops every time something is flashed via CWM

Hi, I've been having some problems with my Xperia Play getting stuck in a boot loop after flashing anything, or restoring a backup in CWM. This includes mods, like Adrenoboost, and the NXT Lockscreen, to themes. I have the Xperia Play R800x with an unlocked bootloader (via unlock code from Sony) and I'm using stock 2.3.3 Gingerbread, with the stock Kernel. I boot CWM by hotBooting LuPuS with Fastboot. I'm not really sure what to do because I really want to install these mods, and because restoring my nandroid backups also gets it stuck in a bootloop, I have to reflash the stock .ftf with FlashTool and reroot it every time.

Hi. Not all mods are 100% compatible with stock ROM so you should use a custom one. Many custom ROMs are better than the stock one.

It worked fine as soon as I hotBooted it with LuPus. I'm gonna try installing the other ROM I wanted and hotBooting LuPus

Strange, I have the opposite problem: lupus doesn't boot any ROM for me, excepting ICs ones.
In fact, to install a GB ROM I always have to flash first the stock rom and fw, and then flash the ROM with a custom recovery. Anyway by "hot booting" you mean custom recovery right?

No, what I'm doing is using Fastboot to boot the phone with the kernel, without flashing it, to test it out. As soon as you shut the phone off, and turn it back on, it boots with whatever kernel is flashed on it

That's what I mean with custom recovery :laugh: (don't confuse with custom kernel).

When I had stock kernel I would boot LuPuS just for CWM, but I'll hotboot kernels to see how well they run

So here's what you need to do, since you want stock and and fastbootalot for recoveries y don't you download xperia play clockwork mod app? It's version 4 or something like that don't use xparts it don't work with our Verizon plays since you have root this will install recovery for you to flash Roms mods etc
I'll edit later with a link to the thread that has the clockwork mod app install that MAKE A NANDROID before you flash anything it helps worse case you hotboot lupus to restore your nandroid you have then reboot and guess what stock 2.3.3 Rom and kernel

No I got everything to work fine. I have LuPuS flashed on, and I'm using the xElite Gamer ROM with no problem.
