Seen as you flashed the kernel, ill take it your bootloader is unlocked. So just flash an ftf in flashtool. I personally use .62 for R800i. I cant link u as im on mobile device, but use search "xperia plat ftf"

You didnt turn on usb debugging on before you got the bootloop your stuck now. To turn on usb debugging your supposed to go to settings on your android phone itself and enable it there. The only to turn on usb debugging for you now is your forced to know how to use the terminal on your pc with your xperia play plugged in.

Are you flashing a different rom in cwm than Gin2Ics_v.1.7.4_lite? Try other roms in cwm that are compatible with DoomLords advanced Stock.

Advance stock kernel is ICS. Marphytons ics would be fine.

I think the kernels that include a recovery that will allow installing aftermarket zip files require an unlocked boot loader..

cant flash kernel
It says
FAILED (remote: Command not allowed)

Hi Guys! Good News! Advanced Stock Kernel is now Up! Please proceed to this link to download the file.. if you followed the steps provided from post 1 what you need to do is to copy attached file to internal memory and flash it via recovery.
The EASIEST way is just simply download the file from this post Advanced Stock Kernel Kitkat extract boot.img using Winrar or 7zip to your desired location. Using Flashtool click lightning select Fastboot then select boot.img you just extracted then connect your phone via fastboot, Flash! then Reboot!
note: To completely fix root permissions simply reboot your device to recovery mode then reboot system via recovery it will ask you to fix root just simply navigate to fix and select then it will automatically reboot..

Even if I can put CM11 without root, so if is possible which guide i have to follow?
Sorry for disturb.

Damn, I was doing the "rooting", following your guide (the first), I flashed the first file with flashtool and it worked fine, then when I went to move the folder "DooMLoRD_Easy-rooting-Toolkit_v18_perf-event-exploit" in C:\ and started the "runme_win" forgot to run it as an administrator and because of this or not the dos was stuck, I close the program and open it again as administrator because thought was this, but, when i run again the "runme_win" come out several errors then the procedure finish, the errors are about "Impossible found the path...", I checked even on the phone and i don't have nothing like SuperSu or other... possible solution?
I noticed that the phone number info Build is always 6.2.B.1.96, but if I flashed with "XperiaS_LT26i_6.2.B.0.211_KernelOnly", should change, right?
Help me
N.B:
The first time that i run "runme_win" without rights of administrator, the dos told me: "STARTING,WAITING FOR DEVICE,daemon not runnig, starting it now, daemon started successfully" then stops at this point and you can not do anything but close the program."
While the second time with rights of admministrator: "No such file or directory, is come out different times with several files"
EDIT: I solved, I tried again without administrator rights, I got this errors:

Yeah, that run as administrator messes up a lot, You have to run it normally. So You got rooted and have a recovery, right?
About the version number, only the kernel number was changed, not Your entire firmware, so the firmware number doesn't change in "About Phone ".

Huh. Weird. You have to press volume up when You see the blue LED while booting. Try pressing it 2-3 times consecutively.
Don't know why I din't mention his earlier, but since You have an unlocked bootloader, You can flash a doomkernel. It has pre-installed recovery and all. DoomKernel

I solved. After the failed installation of CM11 my devices was blocked at LOGO Sony....
I got the firmware .96 and flashed it, after root with toolkit, and CWM the recovery on the phone, then I have installed CM11 and Gapps, all good.
The unique thing, is that, with the Installation of CM11 through CWM recovery, after the CM11 is started, I tried to go in recovery but instead of the CWM recovery there was the TWRP recovery... however all good, the recovery work well as the CWM.
Now im fiding the best rom for the Xperia S, do you have some advice?
I really don't know, and CM11 seems a bit hesitant in routine operations, maybe because is a Beta...
Regards!

Ah good that You got it solved. I would recommend Carbon ROM, but it has some issues going on currently. Try PAC, it is good one, and very stable for now.

[STOCK] H815 20A Images + Flashables + KDZ [system + boot + modem + bootloader]

}
These are for the H815 variant only. Files are from software version 20A (Android 6.0 Marshmallow).
Included below: TWRP-flashable stock rom, boot, modem and bootloader zips. KDZ and individual images are also included.​
*There is NO anti-rollback qfuse used in this update... you can downgrade using LGUP HERE. You can also use LGUP to flash the 20A KDZ.
Please do not mirror my files!
20A NOTES...
1. Notifications may not work with all apps. To check for possible missed notifications go to Settings, battery/energy saving, battery consumption, ignore optimization.
2.Knock code has been removed but will return in a future update.
Requirements:
You must have TWRP 2.8.7+ installed to use these files. Thanks to Dees_Troy as always for that. And, of course, you must have your bootloader unlocked for TWRP to work. Currently only H815 EU and SEA variants have official unlock through LG's unlock page HERE. Please do not ask if "model x" is supported... did you unlock via LG's official unlock tool? Yes? then you can use it. No? then you can't. If you have a locked bootloader and want to ignore all warnings and try to flash anyway... HERE is the thread for that (enjoy no root). How's the saying go.. imitation is the sincerest form of flattery? :silly:
Super Duper Safe Install Directions:
Some bootloader unlocked users have had various issues. Despite these users being in the minority I have decided to write up a step by step tutorial to follow.
1. Download the modem, bootloader and system zips listed under the download section and place them on internal or external sdcard.
2. Download 20A repacked boot.img HERE or HERE and place on internal or external sdcard.
3. Download latest SuperSu zip HERE and place on internal or external sdcard.
4. (re)Boot into TWRP
5. Backup current partitions: boot, system, data, efs
6. Install the modem, system and repacked boot.img (no bootloader/supersu yet) (install button > select zip > press "add more zips" > select other zip > repeat)
7. After all 3 zips finish flashing hit the Home button > Reboot button > recovery button to reboot recovery. (if TWRP asks if you want to install SU, NO!)
8. After rebooting into TWRP install bootloader and supersu zips.
9. After both zips finish you're all set to boot into a rooted M. Enjoy.
Notes...
The reason for the above order of operations... some people who flashed this but didn't root were losing TWRP due to the "recovery-from-boot.p" file in stock system which rebuilds stock recovery. By flashing the repacked boot.img and supersu it should rename the "recovery-from-boot.p" file to "recovery-from-boot.p.bak" and not error due to the repacked boot.img... which makes sure TWRP isn't removed. The reason for flashing bootloader last (after rebooting recovery) is because some ran into issues during the flash process and if getting stuck AFTER flashing bootloader causes issues flashing KDZ using LG Flash Tool 2014... so this route makes sure all other files are flashed first before locking yourself out of KDZ flashes. YES you can downgrade still.. but only through TWRP or using root.

CODEFIRE DIRECTORY
Downgrade:
If you decide M is lame and want to go back to Lollipop I wouldn't blame you. Currently 20A is in a "late-beta" stage with options missing like Knock Code and the ability to merge sdcard with data. The only gains seem to be Doze, updated Google Now, the ability to choose which permissions apps have access to... and your About Phone settings now saying Android 6.0. To downgrade:
1. Download Lollipop flashable Modem and Bootloader zips. 10D/E HERE... 10B/C HERE.. 10A HERE and put them on your internal or external sdcard.
2. (re)Boot into TWRP.
3. Restore your previous backup (boot, system, data)
4. After restore has finished hit the Home button.
5. Install the modem and bootloader zips.
6. Should be enough to get you back to Lollipop.
OR
Use LGUP HERE to flash a previous KDZ version.

Don't have official bootloader unlock? This guy claims to have a working method HERE...

I would still expect better than that, frankly I see no difference between 6.0 and 5.1

Oh crap I forgot we will loose xposed goodies with M. Let's hope we will see roms with integrated mods a la Leedroid and Viper roms
Sent from my LG-H815 using XDA Free mobile app

normally with 6.0 we had to know merge sd card and internal memory? we can not

Upgrade/downgrade s10+ to Q to Pie or Pie to Q WITHOUT losing data both rooted unroot

Hi guys.
GUIDE FOR INTERNATIONAL S10, S10+, S10e with unlocked boot loader!
I been seeing some post/questions that is it possible to downgrade from android 10 to android 9 and vice versa WITHOUT losing data or apps. There were quite some posts so instead of answering each n every post i see i thought to post a simple guide and confirmation.
Answer to question.....
The answer is YES can upgrade and downgrade WITHOUT losing data or apps everything works perfectly like never touched at all.
Guide...
Confirmed tested by me several time believe me more than 7 times i upgraded and downgraded.
The guide to do so is simple every time use HOME_CSC either to upgrade or after upgrading to downgrade you won't lose anything never use CSC i recommend to delete it just to be sure. You must every time use HOME_CSC.
Guess what one more very interesting thing.
If you are rooted(magisk) if you flash pure stock firmware and recovery too you wont lose data if use HOME_CSC and if after flashing stock use patched ap or patched twrp(recovery) it will get rooted again without losing data if used HOME_CSC.
Last thing.
If get stuck on samsung logo during boot with magisk then just go to recovery and use file manager browse to /data/adb/ delete magisk module riru edxposed if installed other wise it will boot fine if not installed.
I will help further if needed.
Regards.

If you have AT&T firmware (like I do) then the home csc file is very hard to get your hands on.

For US carrier you can follow this thread.
https://forum.xda-developers.com/s10-plus/how-to/g975u-g975u1-firmware-links-t3905897
This is is providing whole firmware with HOME_CSC. You can get/request firmware from him.

How can I do that? I upgraded to 10 but literally I hate it. I wanna downgrade to 9. I have no idea what you talking about home csc...

To flash firmware either to downgrade or upgrade you must download firmware for your phone and odin windows pc software.
When you download samsung firmware according to you phone model. It is a zip file that zip file when extracted have 5 files in it. You then open odin select files according to odin slot mentions i.e. for ap select ap for bl select file bl for cp select cp for CSC select HOME_CSC all files are extract from downloaded firmware. Put phone into download mode and connect and start flash.
Below is an example of extracted files from firmware archive.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"

Quick question. Does one have to eliminate the .md5 extension in the filename before patching? I had to do this to patch the AP file for rooting. It worked for me but I just want to make sure it will not be a problem if I do the same for the other files if I have to install TWRP. Thank you.

It wont be a problem if downloaded from trusted source and properly.
Md5 are needed by odin but if md5 extension is removed it is also fine.

If i wanted to upgrade from android 9 to android 10 on a rooted(magisk) s10 would i first need to relock my bootloader?

No.
You just have to use patched firmware and have patched recovery in it.
Or
Download latest firmware and your favourite recovery patch them edit firmware and put patched recovery in it.
Now use odin.
Hope you know process in detail about patching and odining.

I don't recommend downgrade if you upgrade bootloader to Android 10. Downgrading bootloader to previous version is not possible.
I tested downgrade from stock Android 10 to Pie and it doesn't work.

https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Q15) Can I downgrade to an older build?
Answer: It depends on your current build. Sometimes you can downgrade, sometimes you can not. Read detailed answer to check.
Detailed answer:
You have to see the bootloader version of your current build. Samsung tends to upgrade bootloader versions regularly so downgrading is not always possible.
For example if your current build is G975FXXU3ASG8, and you want to downgrade to G975FXXU2ASF3, it will not be possible.
Moving from 'XXU3' to 'XXU2' is not possible since XXU2 is an older bootloader version, and because of Samsung's downgrade protection, it will not allow the older version to be flashed.
When attempting to flash, Odin will show 'FAIL' in the flash window, and the bootloader screen on your device will display this error:
SW REV CHECK FAIL(BOOTLOADER) DEVICE: 3, BINARY: 2
This is showing that the device is currently on a v3 build, and the build being flashed is v2, so it will reject the file and abort the flash immediately.
If however you want to downgrade from G975FXXU3ASG8 to G975FXXU3ASG2, you are free to do so, since both builds are labeled 'XXU3' and are on the same bootloader version (i.e: v3).
Note: Some builds will be labeled 'XXS', and the same reasoning applies to those builds as well. If the bootloader version is different, you can not downgrade.

Actually without twrp you wont have access to system partition. Anyway try this... connect your fone with pc and use adb to uninstall the command is
adb wait-for-device shell magisk --remove-modules
