[Q] Flash bootics.img on Xperia Play

Start by saying I'm very new about Android and smartphone in general.
Four days ago I got my first smartphone, a Xperia Play model R800i and some friends suggested me to install ICS. I searched on the internet and I have found the Xperia Play Development forum. There, I found a really interesting ROM called "New Express ICS".
I downloaded all the files and I started to follow the guide. I'm stuck at the second point (I believe this is ridiculous): I can't get into the Recovery Mode and I didn't get if I can flash the custom kernel (bootics.img) on flash tool.
I haven't rooted my phone, it's 100% virgin, yet.
Can someone explain me what to do? I'm searching answer here and on google for three days and I'm getting even more confused.
Sorry if my english is not perfect, it isn't my first language.

You need to unlock bootloader before fastboot a kernel (bootics.img)

Thank you very much, I'm going to do this. Is this a good guide?
After that what I have to do? How I will flash the rom? Sorry for all these newbie questions.

You should read all his guides.

Thanks for the link, it's very useful! Just a question: what do you mean with "read the root"? I have to root the phone?

I rooted my phone and I found the superuser app on this. Then, I unlocked the bootloader and the superuser app disappered, is it normal?
One more thing, how I flash the custom kernel and the ROM, now?
EDIT: Fail, Superuser is installed, yet, I didn't notice that
EDIT2: Why I can't get into the recovery mode?

I see you unlock your bootloader, good job! Place the ROM zip into your SD card first. Next, to get into recovery mode, just fastboot the kernel you want.
-Power off phone.
-Hold search button while connecting to PC via USB
-Open flashtool, click the thunderbolt icon, select fastboot
-Select kernel to flash (select your kernel bootics.img)
-Wait for 2 seconds and voila!
After that, power on your phone, when blue LED lights up with a vibration, spam volume button / back button (depends on kernel) then you'll be able to enter recovery

Again, read his guide on flashing kernel and roms: http://forum.xda-developers.com/showthread.php?t=2054512
Which kernel you flash is depended on the rom you want to use it with, you need to flash a GB kernel if you want to use GB rom, ICS kernel for ICS, etc, although some kernel are compatible with both ICS and JB. Search the development section for kernels and roms. If you flash a rom and it fail to boot, it mean the kernel currently installed is not compatible with that rom.
About ClockworkMod Recovery:
If you flash a custom kernel, it will likely have ClockworkMod Recovery included. Or if you are using stock Sony firmware, use the "CWM installer version 5" from this link to install CWM. Sometimes you will get a status 7 error when you try flashing a rom, it might mean you have to use a different version of ClockworkMod to flash that rom successfully.

First of all, thank you both!
Can I flash bootics.img in the Flashtool? The fma965's tutorial speaks about a "*.zip" file besides a "*.img" file.
Also, he says to use fastboot package that I have already used to unlock the bootloader.
EDIT: I need Busybox? What is it? I didn't get it.

Flash boot.img in Flashtool/Fastboot as instructions above from jeff7424:good:Zip files are what you put on your sd card and flash with cwm recovery, these can be either roms, updates to roms,zip files to change appearance, performance tweaks, too many to mention.
So .img and .ftf files use in Flashtool/Fastboot and zip files use on SD card to flash with CWM recovery.
Not to complicate it too much sometimes the boot.img comes in a .zip file you need to extract this to use in flashtool/fastboot with winra/7z unzip programs
Edit; Busybox download it with Superuser app on your phone or download a app from store to update your busybox
What is it?http://en.wikipedia.org/wiki/BusyBox

But I don't need busybox to flash kernel and ROM, right?

You can get busybox from Play Store, just search Busybox installer, install it, open the app and install busybox.

Root your phone with zergrush, that will give you busybox too.

In that case, I've already installed it.
EDIT: What I have to click? http://puu.sh/1VVgK
"Select Kernel to flash"?
EDIT2: I don't need a custom firmware?

Yeah select kernel to flash. Nope you just need an unlocked bootloader.

I DID IT.
But I'm a bit disappointed because Crash Bandicoot disappered...
Thanks everyone, by the way.
For the future update, the phone will format again?

[Solved][Q] How to update/change Custom Recovery

I wanted to try PSX Custom ROM 4.4.
this is the thread
http://forum.xda-developers.com/showthread.php?t=2543176
I'm running on TWRP using freegee app on playstore and flashed using the "classic method" (there was another method the mako method) and it doesn't flash PSX because it keeps failing. apparently, the updated TWRP is needed which is supplied in the said thread.
There are guides on how to flash a custom recovery, but i haven't found a guide on how to update or change from a preexisting recovery to a new one
so the question how do i safely update twrp or maybe in the future flash to CWM.

Simply flash the new recovery from an existing one, that's it. "New" doesn't mean newer version, just the one you want. I never had problems flashing different recoveries on any of my devices.

Flash from the existing recovery, whichever one you have (I understand you are running TWRP installed by FreeGee). So, just go to TWRP the same way you do for flashing the ROM, and flash a zip for an updated recovery (TWRP or CWM, whatever you need, doesn't matter) that you downloaded.

Also freegee now updates recovery withouy touching bootloader again as mentioned by shelnut.

Flashing S3V3N's ROM

I can't flash clockworkmod recovery provided on that page. I install the .apk then flash recovery and then reboot recovery but it just does a normal reboot. I saw there is TWRP recovery. Can I flash the ROM through TWRP? I asked on the ROM page but nobody told me a solution. Does someone have a clue why I can't flash clockworkmod recovery or if I can flash it through TWRP recovery?

Would be helpful to give some information as Most variants have a locked boot loader and can't install a recovery.

maybe you remove the permission for recovery installer from supersu app and grant new permission when you install recovery?!

S3v3n mod is for d855 running 10h stock only.
You need first to root device using purple drake lite,then install CWM IPK and then run it from same IPK,then having s3v3n mod on Device storage,select install zip,aroma installer starts you select options and install.

I rooted it with stump. Does it make a difference?

[help] My G3 doesn't accept custom Roms

Dear all, as i mentioned My LG G3 F400s doesn't accept any custom roms but no problems about stock roms
It was accepted in the past but not now, I tried everything to solve this problem but nothing work
before I used cloudy and fulmics without any issues but last month I tried to flash OTA I got Boot-looping then i used flash tools to flash kitkat.tot and rooted it to flash custom rom but I got boot-looping again
I repeated all steps and after flashed kitkat I flashed Lollipop.kdz by LGUP and it accepted but after flash the custom recovery I got "secure boot error" message
I did that many times with different versions of custom recovery and custom Rom (Cloudy and fulmics) but after all steps I got Boot-looping
Now I am using MM stock Rom but there is no root for it yet, So any help please.
sorry for my bad English I tried to explain as much as I can.
Thanks.

So you mean you are unable to flash recovery on your device.
Which recovery and recovery version are you flashing. From where you are downloading the recovery.
Have you tried to install recovery using autorec. If not give it a try from
http://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396
Tell me if it fixes you problem.

my problem not flashing recovery, i already flashed it many times (twrp) but after flash the rom with the recovery I got boot-looping but now I am in MM so I cant flash recovery (No Root)
any way I will try to flash recovery with AutoRec in MM and I will replay
Thank you.

Unfortunately , autorec. need root access so i am not able to use it.

G3 has root access for marshmallow why are you saying its not ?? Try flashify for twrp flash check youtube for a demo .... After successful flashing then root ur device download kernel auditor check to see if u have stock kernel or previous custom rom kernel always make sure u have a backup of root + stock rom in twrp always

Use kingroot apk to root it temporary using internet connection and then flash recovery by flashify or adb method. After that flash supersu zip or just flash rooted custom roms.

Easiest way to apply OTAs on Oreo with TWRP?

I am stock rooted. I got an OTA that I'd like to update but it looks like it doesn't want to flash through twrp. I want to stay stock rooted. Do I need to reflash entire image?

Try Flashfire.

If flashfire doesn't work (like in my case), just flash stock recovery and apply OTA. You'll have stock unrooted ROM and you can follow these steps:
1. have stock rom + stock recovery
2. use "fastboot boot twrp.img" (boots TWRP without flashing it)
3. install magisk from TWRP
When OTA cames in, I just apply it and then repeat steps 2 and 3.

Do you know if OTA will work if I have any other system modifications? I pushed some apps to /system for example. :silly:

As far as I know, even mounting system as R/W can prevent OTA update. I wouldn't even try to apply OTA with modified system partition. In your case I would download full factory image, flash everything without data wipe, root as suggested above and apply next OTA without struggles

Have you tried flashfire? I'd recommend it. You can flash the ota, download the full ota from Google, and retain root and a custom recovery. Support chainfire and get the pro version. Although, functionally there is no difference.

Flashfire worked. I had to uninstall SuperSU and reinstall magisk and TWRP but much easier than wiping everything and flashing.
