r800x Sony Ericsson boot loop

So I got my bootloader unlocked and it seems that every single kernel I try does not work. I've tried the cdma kernel for cyanogen and it doesn't boot (the update.zip doesn't flash in clockwork either... it gives some error and aborts in the middle of it.)
the closest i've got to working is using the doom kernel v3 and that gets stuck in a Sony Ericsson bootloop. if it matters i used it with zerorom v4.
i have a rom that i can boot from to get into clockwork that i got from Alejandrissimo when he unlocked my bootloader. what can i do? I know that i can use flashtool to flash back to stock, but i wouldn't be here if that's what i really wanted. I want a rooted custom kernel and a custom rom, but I can't seem to find any that work for me. any ideas? clearly i'm doing something wrong since other people seem to not have this problem.

Anything yet?
I've been having the same problem, and have had NO luck finding a solution. No matter what kernel/rom I try, I ALWAYS get the 'Sony Ericsson bootloop'. This is getting incredibly frustrating!

First, have you make sure to wipe dalvik/system/factory restore using Team Win Recovery Project or Clockwork Mod? I found that I was bootlooping because I had missed that step. If that doesn't work, you can always resort to flashing on the stock firmware. It won't relock your bootloader, so you can retry the rom/kernel once you get it up and running again. Hope that helps!

It doesnt matter what you do. Cm does not support CDMA xperia play.

I've made sure to do all the proper data wipes. I've tweaked many devices before and for some reason, this phone is the most difficult one to work with. After the 6th factory fw flash, I'm throwing in the towel for the time being. Thanks for the help though. I really hope a solution can come for this. Judging by the amount of views for this thread, it doesn't seem like an isolated problem.

Have you tried to go into recovery after flashing the kernel?...I used paxs cm10 it booted fine.

After flashing the kernel, I can. As soon as I load the rom and reboot though, the bootloop starts. At that point, I can't get it to boot into recovery anymore.

What ROM are you trying out...& what kernel... Also what model# do you have (r800x/i/a/at)...how are you flashing by the way... Cmd or flashtool?...just trying to find out as much as I can in order to help where I can.

r800x (Verizon). I'll have to get back to you on the specific roms/kernels as I'm not currently on the computer holding them, but it's been 4 different ones of each (2 ics based and 2 jb based). I've tried different combinations of the compatible roms/kernels, and I've been using cmd/fastboot for the kernel flashing.

you do have your bootloader unlocked right...

Yes.

& what command are you fastbooting with...I know it seems like we are playing 20 ?'s but I've only ran into that problem when I loaded the temp recovery... If you flashed any Jb ROM its important to format system before you flash the ROM. Might also be needed on certain ics roms.

[Q] Flashing Roms, Recovery help

I got my Xperia Play R800x yesterday. Since then I have rooted, unlocked the bootloader, and installed crash team racing. I have been reading through the forms before and after getting my phone. But Im still confused on the whole flashing process. From what I could gather if I want to flash either a kernel or rom I must use fastboot. Which is a program you run on your computer while the phone is in fastboot mode (black screen, blue led). My problems are I have yet to find a DETAILED process on how to do this. I also am wondering if I were to install clockwork recovery if I could just flash roms and kernels through it. I know everyone on the form says they you cant but they all have locked bootloaders. The final thing Im confused about is flashtool. What is it used for? In one form is sounded like someone used it to unbrick there phone but Im still unsure. Any help that can straiten this up for me would be GREATLY appreciated.
Edit: If this helps you help me I have recently come from a droid X and HTC Eris. Both devices I know my way around them.
Oh and thanks for the people who posted in my last thread. THIS PHONE IS SICK!!!!!!!!

Dont have any answers for you since most of them are in the forum ; but a thing to point out is that since you have a r800x the amount of roms you can flash are limited.

Could I at least get some links. I have been digging around for a weak and still haven't found anything. Like I said I have an idea about everything I just need some help clearing it all up.

Ok, I finally found a form that explains flashtool and how to use it. But I still would like to know about the clockwork recovery.

You can flash roms through clockwork mod. But you can not flash kernels, the reason for this is both the kernel and recovery are held on the same partition /boot/, obviously flashing a kernel overwrites /boot/ partition so CWM cannot write to the same partition is it running from.

You can flash nandroid backups from CWM recovery
Your selection is limited tho because this phone has limited people working on it lol.

Yeah I know the CDMA rom department hasnt developed yet, but it will.
But you two are saying two different things. Can I only flash nand backups with the clockwork recovery or can I flash a rom. Thanks for clearing up the kernel part though.

Nice!!
Now when you say you were the first to make a rom that was flashable in clockwork recovery. Does this mean that the rom has to be specially made to be flashed with the clockwork recovery or is this just because everyone uses flashtool to flash roms?

To be flashed from recovery, a rom has to be in a certain format, and contain an update script and binarys that tell recovery when to mount and unmount partitions, what partitions and directories to copy the files to and what permissions need to be given to certain files/folders

Problem with flashing custom rom

Ive got this message in cwm when was restoring (jj's hybrid for locked bootloader): no app2sd partition found, any ideas?
Locked Bootloader Arc S.
When i want to format sd-ext --> same message.
Prince

Bump
Prince

That means that CWM didn't find a second partition in your SD card used by Link2SD.
Is it working fine, JJ ROM?

Im just wondering if i can flash it with this 'error'.
Prince

I presume jj's rom has app2ext built in, but it shouldn't affect the rom. But check on the rom thread.
sinkster©

I was asking, but no1 replied.
Prince

It will work. That "error" is just a check if a sd partition exists to make use of. Wont affect sysyem if missing.

hints that migh be helpful to prevent trouble when flashing custom roms & kernels
hi there,
i'm not entirely sure if this will help you but generally speaking i came made a few observations about the fact that some people, mostly repeatingly the same users, encounter problems with their custom roms and/or flashing them, while others don't, albeit they are using the same devices.
i myself use 3 different devices, all rooted and running on pac 4.3, always latest nightly, as there are GT-N7100 - GT-I9100 - Nexus 4
not to the point
a) other than most other users i usually clean cache and dalvik cache as well before and after flashing the new rom and/or new nightly
and never encountrer any problems except those which everybody, using the same rom and nightly encounters.
b) whenever i flash an totally different rom and/or upgrade and/or downgrade to another level of android os, i.e. from 4.2.2 to 4.3, i perform
a clean install, including not only a factory reset, but as well a format sd-card, format cache and format system etc., again i cannot proof
which of these steps make a or the differnce but however, i never have problems others than thosw which everyone has with a version.
c) when using cusome kernels and due to the fact that some roms come with a kernel included, as well as with a custom recovery included,
it is strongly recommended not to forget to flas the kernel again after each flashing the new rom. one good example ist dorimanx kernel
for GT-I9100 which will not boot into recovery and reluctantly boot at all after a new flash of a pac nightly without reflashing the kernel.
d) try to fix permissions on reboot instead of doing it from recovery. one reason is that not every recovery has this option and further i
found that when fixing permissions before the first boot after flashing a new rom, there might be bootloops, albeit i cannot explain exactly
why that should, but however, sometimes it's better to be on the safe sid.
e) try to run whether the lastes version of custom recovery for your device, and or the use the included custom recovery of the rom or the
kernel. this again is one thing that can help to avoid some unexpected and hard to explain bootproblems and/or fc's etc.
hope that i could give you some new ideas how to avoid trouble while using custom roms and other hacks

You must use ICS kernel, either unlock bootloader and install custom ICS kernel, or first install/update to stock ICS and then follow the same method.

First install stock ICS firmware, Android 4.0.4 (4.1.B.0.587 or 4.1.B.0.431), and then install the custom ROM. Did you do it so? Can you write the file, which you used?

no..i flashed only base version 4.0.2.A
i always flash "LT18i_4.0.2.A.0.58(2.3.4)_HK" after every bootloop, i not tried to flash 4.1.B.587....few month before tried it to flash but i think it is not able to flash because of system partition is is less because of 4.0.2.................well benifit of installing upgraded rom "4.0.4 (4.1.B.0.587 or 4.1.B.0.431)" and are you sure after that i will able to install it..?

Backup Question

Hi Guys, a simple question:
Does a cwm backup also backup the kernel???
Thanks

It does not. The recovery (CWM) is inside the kernel, so it cannot include the kernel in the backup. On other phones it does, as long as the recovery is a seperate partition (not in the kernel).

^ This is absolutely correct and a perfect explanation.

And if i install cwm with x-parts???
Or is there an other way to do this ??

Any way to backup a kernel? If you ask me, the kernel doesn't really need backing up as all it takes is "fastboot flash boot boot.img" to reinstall the kernel.

This may help ya^

You said your friend has same setup.

I mean the same setup but instead of lupus v9 he has lupus v8

You cannot do that from your phone. You will need a pc, but fastboot is easy to set up. In this guide you can find the download link for fastboot+adb only. (I didn't add any variables, and it worked fine. This will make sense when you have read the guide.)
Then you'll need to find the lupus v8, and just flash it. I don't think you can extract a kernel from a phone, though.

Yes you can, i just found a few for samsung and htc devices, but not for xperia devices.
Well anyways ....

[Q] about roms (stock/custom)..

hi..
i have a stock rooted and bloated xplay (not much time to fiddle) w/c i bought a year ago.. so i was thinking of changing roms and i plan on using the phone for gaming.. i have read some thread about pros/cons of custom and stock-based. others say that the stock rom is still the best for gaming (debloated of course).. so my question is..
should i go for a custom rom..? or stick with stock..?
if i'll stick with stock.., what's the best baseband(?) ..? currently mine's on .42...
what are the apps w/c are safe to delete..?
as for overclocking.., what is the best kernel that you'd recommend..?
thanks...

Xperia NXT lite with doomkernel

i was looking into that actually...
but some cons have given me second thoughts.. like wifi issues and unsupported touchpads (other roms).. that's why i'm asking about stocks..
this will also be my first time flashing custom roms.. kinda scary.. wehehehe...

I think you should stick with the stock. This is the most.stable & supports full touchpad.
Custom roms are not as stable as stock...
I think you can just use v6 supercharger or supremacy script to make your rom fast...
[ you have to do it manually with smanager]
Press thanks if I helped..
Sent from my ST18i

thanks.. maybe i'll try them both...
i just want to ask for the list of bloatwares.. : )
thanks

First of all, you have to give MORE info about the phone: locked/unlocked bootloader, phone model.....
I advice you to get a stock-based rom, instead of sticking with the stock one, because those are inproved with some tweaks that cannot be flashed on your current stock, and have built-in apps and are already debloated.
If this is your first rom flash, just follow this steps:
BEFORE DOING ANYTHING, get the stock firmware that fits your region and stock android version if you want to go back from here or anywhere else
- root with any method, I recommend SuperOneClick
- install ClockWorkMod via RecoverX
- install TitaniumBackup from the market, and backup all user apps you want have in your new rom (be careful, some roms and kernels doesn't go well with backup restoration. Check the rom's thread for backup issues)
- reboot into CWM recovery and do a nandroid backup. It will save everything and you can restore your phone to its initial state, to the point you can not tell if it has had any changes
- flash the rom following the instructions given by rom builder
- flash any addons you want after rebooting at least one time, every addon separately (1 reboot after every addon)
- if you want better performance, get supercharger v6 or supremacy script as said before
Now, the stock firmware you got at first is to repair your phone if a nandroid backup restore doesn't do it.
If youwant to go back to stock, just restore the nandroid backup. If you want to take it to the carrier to fix it for whaterever reason, you also have to unroot and delete any app that uses root permissions, like TitaniumBackup. Then, when you see your Play is exactly as it was before doing anything of this, you can take it there safely
And finally, the best baseband is -36 cause it has the more balanced stats between signal reception on gsm/wifi and battery consumption, but some roms use -64. If you're adviced to flash a stock firmware before the custom rom flashing process, thats for installing the needed baseband and some other components. Happy flashing!!!!

All custom kernels support overclock and all are good at it. Just flash the kernel according to your rom cook's advice
And if you were wondering, custom roms doesn't have any problems/bugs if they are finished. You should expect bugs if there is only the first or second release of that rom, but if it's finished you'll be fine by following the steps exactly as directed.
You can try The JokaWild ROM 'S.B .69 Tweaked ROM' FINAL (v3) and DiXperia 2 'Everlasting' | Performance. Stability. Experience. if you want a stable, fast rom. Those have given me good results, but if you want to know which is the best rom you have to try them all cause they don't run exactly they same on all phones, even if it's the same model. Maybe NXT or Aurora rom could be better for you....

While you're dispensing advice, may I ask which upgraded kernel is best to use with R800i_4.0.2.A.0.62_(1253-4437)? That's what I have on my device.
Is there any benefit to actually installing cwm with RecoveryX as opposed to just loading it with fastboot when needed? That is, will I be more likely able to launch it in a crisis if it is installed on the device?

RecoverX is the easiest way to get CWM. Think about it as a quick 3-step process that you will do only one time. You don't lose anything
Additionally, I don't know what process are you talking about, since flashing a clockworkmod.img, installing the CWM app from the market and RecoverX have permanent effects all of them. The only exception is when you change kernel and it has a built-in recovery, you get the kernel's recovery instead of the original one. I recommend RecoverX because it supports the widest range of phone models and firmwares (I have an r800a, but it was not listed as a supported device in the CWM app, so...)
And again, it's always better to have a custom stock-based rom than just the 4.0.2.A.0.62 stock one

So, have you had a happy flashing? I hope so.....
About the addons you don't have to reflash everyting to install them, just flash one by one, separated by a reboot (you can reboot directly into CWM instead of loading to homescreen everytime, that woluld take ages to flash all of them ).
If you were wondering about root, it's not necesary to flash the root addon since doomkernel is already prerooted, so you get superuser since the first boot with it

I have had a pretty happy flashing, in that nothing went horribly wrong
I do think I more or less know what I'm doing now. Heh heh.
As you can see from my sig I am now running lupus v6 and it's been very stable, smooth, etc. And I added the cifs and ntfs modules. I didn't reboot between everything which is probably why I had to load the wifi modules over again, so I'm very glad they were provided. But everything is working great now, thanks.

I don't know you, but I can access my pc files from my Play with "ES file explorer" without even installing CIFSmanager. The changelog in DK's thread says he removed it, but at least for me it works .
To access from the phone to pc you have to put the folder you want as a "shared folder" and give "total control" permissions to "all". For accessing from the pc to phone just do the same with the folder on your sdcard connected to pc and, go to tools/connect to network device and select that folder. Now you can view your files and do streaming by opening the folder on ES file explorer in LAN section and from "My PC", where it appears as a hard disk with drive letter
e.g. music on "Xperia PLAY R800a" (H:/)
Hope this helped. I'm on DooMKernel v14 with jokawild but this has worked on other ROMs

I rarely use command prompt to perform operation cause I prefer to use flashtool instead, and the only time I installed CWM was through RecoverX, so I haven't experienced the difference.....

Yeah I've used the smb built into ES but I prefer to use the smb functionality built into the Linux kernel to using libsmb, which is what's happening when you use es file explorer, or pretty much anything else with built in smb browsing. I also don't care for ES file explorer's interface. Of course, open manager doesn't have smb support...
I have figured out the mtp/msc stuff some time ago.
anyway, pretty much all the kernels have a recovery, some of them have too many recoverys in my opinion so it doesn't really matter. but if you use fastboot boot boot.img then it boots without installing. I don't know if this works for anything but recovery, like if you could boot a kernel this way, probably not. I like command-line stuff. I do use flashtool's gui for ftfs though, of course.

a little off topic..
what should be the sequence..?
from stock..,
nandroid BU, flash pre-req stock ROM, unlock bootloader, flash custom ROM,..?
- or -
nandroid BU, unlock boot loader, flash pre-req, then custom ROM..?

you have the sequence right, I don't know if nandroid backs up the kernel. I would guess no, but I could be wrong, and hope I am.
you don't care anyway. you can reflash back to a stock kernel. just make very very sure you never flash a cdma to a gsm or a gsm to a cdma. a, at, i are all gsm... if you do that you need testpoint reflash as far as I know.
you should also do a titanium backup, that gets you all the apks on your system now, handy for restoring any games on your current rom that aren't on your new rom.

Well, you can unlock your downloader at any time, by IMEI method through Sony webpage or through alejandrissimo's testpoint method. It is permanent, so it doesn't matter if you change Rom or kernel, it will remain unlocked forever , and if for whatever reason you have to take your phone to carrier for warranty, it will appear locked for Sony (I already did it, and they didn't void my warranty)
Just follow the steps I gave you, it's not that complicated. You can flash first the Rom or first the kernel, it doesn't affect anything, except when you change android version (GB to ICS or something), then flash the kernel first and then the new Rom.
Flashing a rom doesn't change the kernel, so if you're on DoomKernel and "A" Rom, you can switch to "B" Rom and stick to DK, IF IT'S ON THE SAME ANDROID VERSION.
Also you can change kernel while keeping the same rom
And respecting to nandroid backup, it saves everything but kernel, baseband and some sections of internal memory that you should not worry about. That's why you're able to restore a backup with the same or other kernel without any worry
