you use wrong kernel, that kernel for GB and this ROM is ICS

you can use alliance kernel or suave kernel
[Sony Ericsson Xperia Neo, Pro] BlackRatVN:
Well thank you I will try to flash latest 4.0.4 first then repeat the process
[Sony Ericsson Xperia Neo, Pro] thanhhii:
Rangercrew89 please help me to solve this problem, i have done it like you said but nothing change
[Sony Ericsson Xperia Neo, Pro] BlackRatVN:
I installed stock ICS 4.0.4 and Alliance but still unable to pass Sony logo... So I installed Ice Cream Pureness and it runs fluently

Maybe this ROM hates my Neo ;)
[Sony Ericsson Xperia Neo, Pro] Toz1k:
The same problem on my Neo.
[Sony Ericsson Xperia Neo, Pro] archer928:
I use this method :

flash stock ICS .587 with flashtool

flash kernel alliance/suave with flashtool/quickimg/fastboot flash boot

go to CWM

factory reset

go to mount & storage in CWM

format system

format data

format sd-ext (if you have 2 partition on your micro sd)

wipe cache

wipe dalvik

install JS 8.0

install JS 8.1

reboot (wait until 5 minutes, if not boot to home then you stuck)

[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Perfect procedure, thanks a lot for it. I want to explain it a little because I had some problems installing the ROM on my Xperia Neo (MT15i), but finally I done succesfully and I want to share my experience in it.

First of all, for Xperia Neo with Stoch ROM .587 as mine, in this thread a get the CWM 5.5.0.4, thanks to vasiulla:

http://xdaforums.com/showthread.php?t=1870214, only need to unzip, connect the USB cable to device and run the batch file (device must be on), then we have the "Fix Permissions" option in "Advance".

After it, the Bertellio procedure is perfect, only a little sugestion: after point 6, I done a "Fix Permissions" (as "installation procedure" in first page of this thread).

After it all be right, but no "OTA Update app" in my device. CWM dissapears but you still rooted (if you was). Only repeat the same steps as in the begining and that's all.

After the installation, in my Neo, I get free 1,39Mb in /system, install rott explorer (or similar) and go to /system/media and delete Bootanimation.zip (it's too large, cool, but very large for our devices), you can exchange it with another one smallest.

In this point (you have already installed Jelly Sandwich 8.0, CWM 5.5.0.4 installed again and rooted), you must put the OTA update (8.1) into SD root folder. Reboot in CWM (short vol down a lot of times) and when you're in CWM:

- clean cache and dalvik cache

- fix permissions

- install zip from SD Card.

After installation, uncheck "reboot device" and you're again in CWM menu:

- clean cache and dalvik cache.

- fix permissions.

- Reboot device.

After it, you have installed the Jelly Sandwich 8.1, OTA update app now in app list and all is right.

The ROM seems smoothest than Ultimate HD, I had this last week, is great, Antutu 3047

I have installed Apex Launcher, Ram Xpander (great app for us) and Link2SD with a 1Gb ext2 partition for links, now Jelly Sandwich has a Antutu 3414. It's no much difference, but for our devices is important because with only 300Mb of Ram (mine is now 1,8Gb, thanks to Ram Xpander) we need much more smoothness than another devices. I can say I have always on skype and tipycal apps, and two SIP account connected and receiving calls (Whatsapp, Viber, Gtalk, HD Widgets, etc) and this ROM, at this time, is smoothest than another ones for my device.

I hope to solve your installation troubles for this device that is a jewel, a bit short of performance, but a jewel any case.

Thank you for this awesome ROM.
[Sony Ericsson Xperia Neo, Pro] dellipri:
Hi. I would install this ROM on my Xperia Neo.

Here is my configuration:

--> bootloader locked

--> root permission

--> stock ROM with kernel .587

Here are installation instructions:

1. Download ROM and place it on SD

2. Flash latest stock ROM using Flashtool (first time flashing only)

3. Go to CWM (if you don't have it, use X-Parts or flash custom kernel)

4. Clean cache.

5. Fix permissions.

6. Start ROM zip with AROMA

7. Choose "wipe data and cache"

8. When the installation ends don't reboot

9. Clean cache

10. Fix permissions

11. Reboot

I have also installed on my device X-Parts. I launch this application but I don't find clean cache.

I think that I must clean cache from flashtool, isn't it?

What you intend at point 5 with fix permission?

And also with "start ROM zip with AROMA"? I must install from sd card? I will use flashtool on pc...

At least which are languages supported from this ROM??

Thanks for your collaboration,

Fabrizio
[Sony Ericsson Xperia Neo, Pro] BlackRatVN:
Thanks but I did exactly the same and still not working

I guess I stuck :(

---------- Post added at 12:21 PM ---------- Previous post was at 12:18 PM ----------

As you can notice, from step 3 you do inside CWM, not with PC and flashtool

For language support, what language you need? I guess at least the ROM will support English ;)
[Sony Ericsson Xperia Neo, Pro] dellipri:
If it is possible, italian language...

I have not installe CWM on my device, I have only X-Parts...
[Sony Ericsson Xperia Neo, Pro] Ghostfreak NB:
X parts is an app that gives you cwm

Use volume rockers

Ie volume down button to be pressed repeatedly to enter cwm once you see Sony logo
[Sony Ericsson Xperia Neo, Pro] dellipri:
So I launch X-Parts, then under tools I must choose reboot to recovery and when I see Sony logo I must press volume down button to enter in cwm... Is it correct??

Fabrizio
[Sony Ericsson Xperia Neo, Pro] Ghostfreak NB:
Actually afaik I think x parts directly takes you to recovery mode i.e cwm. Once you click reboot to recovery

I believe you clicked install cwm in that app already before rebooting

However if it doesn't just use volume down button repeatedly when you see Sony logo !

Then you enter into cwm :p

[Sony Ericsson Xperia Neo, Pro] DaJackel:
Anyone using "The Alliance kernel mod for ICS (V1.5) and CM9 (128)" or is an other kernel recommended?

Generally Question: Some ROMs have a Neo or NeoV Patch other like this not. Anyone know why?

Thanks for help.
[Sony Ericsson Xperia Neo, Pro] apis10:
I use alliance kernel. Very good, no problems.

This one has the patches built in the aroma installer- very cool stuff
[Sony Ericsson Xperia Neo, Pro] motorazrv3:
Alliance kernel is a kernel, cm9 isn't a kernel its a Rom. Cm9 uses other kernel so you can't use it with js.

Cm9 has its own kernel and you can use it only with unlocked bootloader.

[Sony Ericsson Xperia Neo, Pro] mttca:
You need to read "The Alliance kernel mod for ICS (V1.5) and CM9 (128)" as

"The Alliance kernel mod for ICS (V1.5)" and "The Alliance kernel mod for CM9 (128)"

Obviously "The Alliance kernel mod for ICS (V1.5)" is recommended for JS and not "The Alliance kernel mod for CM9 (128)".

I use that kernel and it runs good.

[Sony Ericsson Xperia Neo, Pro] frank_harmann:
Are you on suavev6 kernel? (Sounds like, as for me these boot stops/loop always happen when out of /system).

If yes, change shardul.swap.mb=0 in /data/local.prop. Then reinstall rom (without wiping /data, just wipe dalvik/cache/system). Chose only recommended settings(+nofrills if you want to oc and stock as wifi option) in aroma but don't install any audio mod and no bootanimation. Stick to noop as io govenor and anything you like as cpu govenor and everything should be fine.

If you are on nightelf i have no idea, maybe wifi module related??

If you want audio mod delete /system/media/bootanimation.zip and you have enough place to install AC!D audio mod.

Besided this installation problem(which are related to suave kernel) it's a nice and fast rom:good: And 7.1 already in work, nice.

[Sony Ericsson Xperia Neo, Pro] apis10:
Same story here!

I had black screens on first 3 flashes.

Night elf worked finally.
[Sony Ericsson Xperia Neo, Pro] frank_harmann:
I already told you what to do for suavev6 kernel! Did you follow the steps?

Maxio probably can't help you as he doesn't own a neo. So it will be difficult for him to fix kernel related problems on a device he doesn't own :rolleyes: Btw, it's not his fault that suave kernel tries to put swap on /system by default (which btw is a bad move as most users probably will forget to disable it and wear their internal nand memory).

Just in case, did you reflash stock wifi modules(http://xdaforums.com/attachment.php?attachmentid=1094273&stc=1&d=1338355397) after switching from nightelf to suave as told in suaves post(http://xdaforums.com/showthread.php?t=1708532)?

Congratulation on the HDMI Fix :D in the earlier version!

1) Is this rom based on Android 4.2?

2) So I am coming from PacMan Rom. Bootloader unloacked Rooted. I understand I have to first flash 8.0 then 8.1 then 8.2! Do I also have to move back to stock before flashing 8.0

3) Is the front Cam working?

Cheers!!
[Sony Ericsson Xperia Neo, Pro] Ghostfreak NB:
1, its based on stock Ics. 587

And not 4.2

2.no need to flash stock

Just do a complete clean install

Including format system

3.its stock based so front cam has no issues

Hi! I would like to see:

-stock calendar widget fully working also with FacebookInsideXperia birthdays

-stock keyboard with the ")" object which is actually missing (don't know if you fixed it after 7.4, but I told you 2 times without reply)

-"No-frills-cpu" directly in settings menu

-stock sony icons, according to me they are the best and I always used them

-little rom size so I don't need to unpack it, delete apps then repack to be sure not getting stuck to sony logo.

-much more wi-fi stability and better battery life

Anyway I think your rom (7.4 for me) is the best for locked bootloader up to now, so keep pushing it.

Yeah, install JS 8.0 as normal rom.

When finished start phone, then shut it off, go to cwm, wipe caches, install 8.1, fix permission.

Start phone, then shut if off, go to cwm, wipe caches, install 8.2, fix permission.

Start phone and enjoy!

--------------------------------------------

PS.: 2G/3G toggles in tabbed quickpanel doesn't works. But the problem is the "semcphone.apk": you need to flash "semcphone.apk" which has 2g/3g working. You should find it in the tabbed quickpanel topic.
[Sony Ericsson Xperia Neo, Pro] simongaiteiro:
Worked for me! Thanks!
[Sony Ericsson Xperia Neo, Pro] Bertellio:
Yeah, I told many time maxio to edit the instructions for locked bootloader in first page.

Also I suggest to highlight in the instructions MaxWorks topic to increase system partition in Neo. I have just done it, it is simple and it solve some issues with those big roms.

I don't know how but after I've increased system partition and installed JS 8.2 my Neo is damn fast with stock kernel and max cpu freq set to 768 Mhz (of course no gaming).

But, I have to tell you, icons are really awful. They are ugly and unreadable please give chance to have stock ones.

Quick Flash instructions (Cos there are some who still don't know)

1. Flash kernel (recommended Nigh-Elf Alliance Kernel for ICS) (don't select the FXP version)

2. Boot into recovery. Factory reset, format /system, wipe dalvik, wipe battery stats(optional)

3. Flash the 8.0 zip. Go through the Aroma and choose your options. Finish installing, deselect the reboot option and end the flash.

4. Install 8.1 OTA update zip. Same, don't reboot.

5. Flash 8.2 OTA update zip. Same, don't reboot.

6. Wipe cache (Dunno why. Maxio said do it, just do only I guess)

7. Reboot phone. It might take a while on first boot, but it will work no probs. Been using with no bugs.

Take the file "DefaultThemes.apk" from the installation file. Then put it into a flashable zip with path "\system\app\DelfaultThemes.apk" then flash it wiping caches.

Reboot and you should find the original themes.

Playstore??

Why am I losing the playstore and getting synchronization problems when I update the OTA's???

I flashed the 8.0 ROM as per the instructions, and then updated the OTA's in sequence (8.1 first, rebooted and after 10 minutes flashed the 8.2 OTA) But from 8.1 onwards, I am losing the playstore and having synchronization issues, thought it would be fixed in 8.2, but still problem exists!! any reasons for this??? I am using Neo L and have come from another custom ROM.

Also the internet connection keeps getting timed out and very slow, despite switching to WCDMA only. I know this can't be a problem with the connection provider because the internet works smoothly on other custom ROM's I have used.
[Sony Ericsson Xperia Neo, Pro] tleung11:
I experienced your first problem.

It happens when I choose not delete ringtones. It's fixed after I re-do the install and choose the "only leave one ringtone per type".

I'm using NEO, I guess it maybe because system space not enough.

BTW, choose "superSU" is not working for me, I recommend choose the "superuser".

For your GPRS problem, go to settings -> wireless & networks -> mobile networks -> access point names

just create one yourself and see if it works.
[Sony Ericsson Xperia Neo, Pro] neo_na:
I chose the options during aroma installation in a way so that it would leave the most free space possible. I chose to delete all the tones and leave only one, chose superuser as well. So, the ROM is pretty lightweight....
