[Q] Need assistance, please - Sony Xperia S, Acro S, Ion

Hello! I am new to the Xda community, and I have a Xperia S. I went throw a lot of Rom threads and read all, even video tutorial and because of that I got confused. Can anyone spare some time (aprox. 10 mins) to answer me some questions, by chatting or here. Please do not make a fool out of me like some other guys around here.
1. if i go into bootloop after flashing CM10, can i restart the phone and go into CWM without flashing again boot.img, and flash the rom again?
2. if i go into bootloop after flashing CM10, do i have to flash the stock rom using flashtool?
3. tell me a simple way to get out of bootloop.
4. flashing the CM10 on my SXS with built number *.2.55 will work?
If I have made anymistakes by posting this here, i would like someone to take it down. Thank you for your time.

I dont have an Xperia yet, but from reading and experience from other phone ...
1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware.
2) if you wiped, try to restart with flashing the firmware again and wiping everything.
3) if nothing working reflash stock, boot stock once to see if it is working without bootloops and then restart from scratch.
4) if also not working .... is it the correct firmware? did you forget something?
There are good instructions for the firmwares, if you do everything as explained, you shouldnt get bootloops. But ... no howto is perfekt.
Its mostly trying as much as possible, till you have the correct way to flash a firmware. Bootloop isnt that bad ...
If you have a way which works for you, keep the steps for later flashing and tell the community what you had to do differently or if you missunderstood some points, even then tell it, because that can make these instructions better.

I would say that it doesnt matter which firmware is on the phone, as long as you unlock the bootloader and the fastboot or flashtool is working.
The custom firmwares use the same methods but might have added recovery for easier flashing later.
You should even be able to downgrade to older firmware with unlocked bootloader and flashing the ftf file.
Its only important to wipe the data, cache and dalvik cache that the firmware is working.

thank you very much but still to solve all of my problems:
You said "1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware."
what do you mean by that? which firmware to reflash CM10? how by restarting the phone? and will i be able to go into CWM without the boot.img?

With different phone and different firmware i had some issues with recovery, specially if i didnt wipe directly after flashing the new firmware without reboot and without reboot into recovery ...
I hope i dont mix anything up. CWM is the recovery (?)
The recovery function is part of the kernel image which is exactly the boot.img.
You can see at the freexperia project page howto install CM10, i cant post links at the moment.
3rd point is flashing the CM kernel (boot.img)
4th point is booting into recovery
From that recovery you can flash the custom rom as described in point 5.
Point 6 is wiping the device, which is neccessary for first custom rom or if you change version (eg. CM9 to CM10) or if you change to a different ROM.
Most bootloops happen if you forget to wipe the device. I am not sure, but most important is dalvik cache, if that one is wiped the next boot takes longer, as it will be rebuilt during boot.
If you get into a bootloop after flashing kernel and custom rom, go into recovery and wipe the device, try rebooting.
If still in bootloop, try to reflash the custom ROM as in point 5 (starting at 4th point) and wipe device after flashing
If it didnt help, try reflashing the kernel and ROM, starting at point 3 and include the wiping the device.
If that didnt help, try to go back to full stock (kernel and rom) and repeat.
But check if you got the correkt ROM for your device.
Play a bit around with the steps, you can even reflash the kernel and leave the rom. I had once a bad situation with bootloops, but they are easy to fix. More important is the part with the kernel, i think there you can brick your device.
But when you follow the instructions you shouldnt have too many problems, just dont jump over a step at the first flashing. But as allways sayd, every custom rom, every kernel flashing can harm your device and you're responsible on your own.
But if you get into problems, write down what you did and you will get help here.
Edit:
"if not possible then reflash the firmware ..." There i had once a problem with a different device. I forgot to wipe after flashing a new version and got into a bootloop. In recovery i couldnt wipe the device fully, something got bugged, but reflashing helped. Reflashed wiped and i could reboot into system. As it was longer time ago i dont remember what exaclty happend, but i think the problem was about forgetting to wipe the device.

Wow Thank you soo much, you lost allot of time explaining this to me, I really appreciate it i understood everything I owe you really
ooh and what do you mean by wipping - all: factory reset, cache and dalvik or just cache?

didnt take too much time
in case of first custom rom, changing custom rom version (e.g. CM9 -> CM10) or changing to a different custom rom: all: factory reset, cache and dalvik
in case of updating (e.g. CM10->CM10): dalvik should be enough, maybe cache and dalvik.
If something not working, do a complete wipe.

As I understand from what I read, you flashed cm10 and are now stuck at boot, did you fastboot the kernel? On my xperia s I always need to fastboot the kernel after flashing a ROM, especially when changing from an ICS to a jb ROM.

No, he has no bootloops, from what i understood he is scared to get into bootloops and doesnt know what to do if it happens.
Hmm, kernel flashing after upgrading from ICS to JB? or all the time?
By kernel flashing you mean the boot.img flashing with fastboot, and its the same file as flashed before?

I've only ever fastboot'd my first kernel, advanced stock kernel. Any others have always been in recovery and never had any issues
Sent from my Android 4.2.2 Xperia S

It seems that you got the wrong Kernel. I'm not sure, of course.
But I had that issue some time ago, and a fix it flashing the right kernel that I found on xda forum. Ohh, dont forget to do the proper wipes.
I hope u solve this as soon as possible.

For some good info on recovering a phone read through the recovery thread in my signature.
Even if you don't have any issues now, you can see what others have done wrong & right.

Cyanogen boot loop

i have googled this and tried multiple ways of installing it but i always get a boot loop. Whats going on?
Hey if you just want to get your phone back again, just flash another firmware from the one you used. Should start up just fine.
have done already but i actually want to install cyn mod. I managed to get as far as the main screen buit then immediately reboots. I cant find wifi modules for latest doom kernel either they arent in his thread.
FLASH KERNEL FIRST (from cyanogenMOD or doomkernel for CM7 etc)
Than flash cyanogenMOD
any other way will make your phone bootloop.
I think you have to unlock BL via SE in order to flash CM..
of course you would likely broke your warranty.
this based on my experience (I'm a newbie too in the android's world). this is what I've done :
1. unlock BL via SE (not all carriers allowed this!)..
2. flash .42 fw
3. follow the instructions given on CM thread by fxp.
it's worked for me.
goodluck.
I've had this problem before. Did you wipe the delvic cache, wipe data/factory reset and wipe cache partition in CWM before you flashed the update.zip?
It would seem it was a specific version of cm that was making it bootloop the one from dooms thread 7.2.0 works fine and also the one before the latest stable release also worked fine. I however found a problem with the spacebar on the keyboard when using the phone in landscape so am now going to try arconium and doom kernel its a shame really because cm from what i used of it looked really nice.
Try 7.1.0.1.
I got bootloop too with 7.1.0.2

Aye thats the one i used but ended up having a problem with the spacebar not working in landscape so am on acronium now which is all good but superuser keeps crashing meh always something eh.
at first im also having the same problem,just follow the instruction by FXP : flash bb56,flash fw.42,flash FXP kernel via fastboot,flash update via recovery,wipe dalvik cache,reboot..

I have this exact same problem
I've done everything I was supposed to, I think, and still doesn't work. It boots, shows me the little Android "Welcome!" screen, and before I have time to press anything or begin setting up my device, it reboots into the Cyanogenmod loading screen. I've tried different kernels, different basebands, every time wiping Dalvik cache, etc. and it REFUSES to work. I'm pretty desperate by now because I really wanted to use this ROM so any help is greatly appreciated.
I also followed precisely rashid.fairus' instructions and it still does the exact same thing.

Wipe dalvik and cache when upgrading to later version, wiping data will reset phone to factory settings and you lose all personal data.

[Q] [Arc S] Installing any JB - same problem

I have a problem with the installation of JB. No matter what ROM I install, after boot, when home screen appear, my touch screen does not respond. I've tried a lot of roms and a lot of kernels. I have unlocked BL. In stock rom I have no problems.
What could be causing this? Should I format system before installing rom via recovery or just wipe data, cache and dalvik? When I should flash kernel? Before/after installing rom? I care about CM10. Plz help.
P.S. sorry for my english

I've tried to do that way but but not succeed
Certain ROMs require phone-specific patch, make sure you install it!
Other ROMs have different downloads for different phones, make sure to download correct one!
If you install wrong phone ROM, touch dies.
All question threads belong here in Q&A so please post in the correct sections going forward.

The problem is caused by the kernal. You MUST have JB kernel to flash any JB ROM. Generally, for each ROM you will find the recommended kernel and the required steps. Do exactly like posted by OP.
As an example, see here: http://forum.xda-developers.com/showthread.php?t=1979829
You can make an idea on the steps to follow.

Ok, so now I have installed Xperia T rom (7.0.A.3.195 v6.0 for ARC/ARC-S). Should I flash V77 baseband, then flash kernel from CM10 FXP150 pack via fastboot, make a wipe (data, cache, dalvik) then install ROM via Recovery, and then install GAPPS and it should work? This is what i'm gonna do, so if I'm wrong please tell me.
EDIT:
(edited in case someone had same problem)
I found the solution:
I had to flash BB 72 and libs, then flash ROM+GAPPS and libs once again, then everything works awesome. (edited in case someone had same problem)

Galaxy Note II Rogers Bootloop (HELP!!!)

I tried installing a rom last week on my Galaxy Note II (Rogers), i followed orders (this isn't my first time flashing roms), and it has been stuck in a constant boot loop.
I've tried everything, wiping cache, factory reset, tried to flash different roms, etc....
I am a mac user (which means Odin isn't an option).
If you guys have any suggestions on how to fix this it would be greatly appreciated.
What rom were you on and what rom were you trying to flash originally? Also what recovery are you using? Need a little more info because usually wiping caches dies the trick. Provide a link to the rom you were trying to flash of your can.

This is the rom, i was using CMW to flash it, then it made me switch to TWRP (think its called that)......hope that helps.
Sorry I can't be of more help aside of redoing the installation of your recovery and redownloading the rom ( bad downloads happen) and making sure you do all the wipes (cache, dalvik cache and factory reset). If none of that works I'm sure someone more knowledgable than myself will chime in.
I've never run into a bootloop problem myself, but this might help you out :

Put another ROM on an sdcard. Take your battery out then press the button combo for recovery mode before you slip your battery back in. Then it'll force download mode. Reflash the new ROM after full wiping and you should be good.
Sent from my SGH-I317 using xda premium
Definitely a bad ROM. Run a MD5 checker against it prior to copying to the SD card. Note: your SD card could be the culprit.
If you have a recovery installed, ensure you WIPE everything, Fix permissions (i'm on CWM) and reflash the modem and carrier files POST rom install.
I experienced my first boot loop yesterday but I was able to recover from it thanks to a little common sense and patience. :fingers-crossed:
Good luck!
first of all, don't freak out, a bootloop isn't the end of the world. Sounds like it was a bad flash.
ppl above have obviously told you to wipe caches, and all that stuff and if it hasn't worked then you are still down and out.
I would suggest you get yourself into recovery - not going to explain that here as you said you were able to flash other roms and it didn't work and try flashing your nand backup - hopefully you have a nice clean backup from before you flashed. if so, clear caches, etc and then try flashing it it should be back to at least working.
your nand backup will have all your stuff in it as you would have had to backup from recovery, which means you'll at least still be rooted. you can then go ahead and get another rom - check the md5 and flash it

[Q]Why do i have problems with installing custom roms

I have locked bootloader, and rooted Arc S. ICS .587. Whenever i try to install custom rom, usually it demands cache and dalvik to be wiped and i do it. But when iinstall it, (i tried 2 roms on with aroma instaler and one without) and on both i got bootloop. Whenever i tried to install mod that also required wiping cache and dalvik i also always got bootloop. When i dont wipe it phone can boot, but features that i wanted to install dont work properly.
I am really intrested in installing custom rom, can anyone help me??? :crying:
Thanx in advance!

[Q] Boot loop after flashing TWRP recovery !

Hello everyone, I have a problem with my xperia S, any help would be greatly appreciated! Let's start from the beginning, I'll try to be brief :
So, I flashed TWRP recovery using the app "RASHR" (I was using the Pure AOSP Lollipop rom when doing this, if it can help), which caused my phone to always boot the recovery and nothing else. I managed to flash the rom again (I made sure to wipe using "factory reset" and "dalvik cache" before installing), and it seemd to work perfectly, but then I rebooted the phone, and got stuck at the sony logo, no recovery available.
I flashed TWRP recovery (stock-6.1.A.0.452-twrp-2.4.0.0.elf) using flashtool, then tried to install another rom (Paranoid Android, found on this thread : http://forum.xda-developers.com/showthread.php?t=2573345). The first boot was successful, but as soon as I reboot the phone, I'm stuck in a bootloop again, with a little difference : when the sony logo appears, the led becomes pink for a few seconds. No access to recovery. Then the led lights off, the logo disappears, and the phone reboots. Again and again. I just reinstalled the same recovery and tried to wipe and fix permissions, but it does not solve the bootloop, and I don't know what to do...
Could it be possible that "rashr" did a bad install of TWRP and corrupted my recovery/bootloader partition or something ?
EDIT : I reinstalled Pure AOSP Lollipop, and now for some reason, no boot loop anymore... I don't understand why, but as long as it works... problem solved !

No, I didn't, I was too afraid of creating another problem xD I just used the phone normally, installed apps from the play store, the last one being nova launcher (but I rebooted a few times after that without any issue)., things like that.
But after applying your tutorials to flash the Lollipop Pure AOSP rom, I think the problems were caused by :
1) a wrong recovery and/or flashing method : previously I used "stock-6.1.A.0.452-twrp-2.4.0.0.elf" which I flashed directly via flashtools with the phone in fastboot mode with the command "fastboot flash boot xxxxxx.elf". And although I didn't reinstall it after flashing the ROM, I suppose it left something in the recovery partition that caused the bootloop... ?
2) the fact that I didn't flash any "boot.img" at all before installing the ROM... inf fact, I didn't even knew it was necessary !
3) a bad ROM installation procedure : wipe, flash rom, gapps and SuperSU and THEN wiping cache and dalvik, restart
4) all of the above (!)
Anyways, after doing it "the right way", everything seems to work correctly for the moment. After installing the ROM, I followed your recovery tutorial using "openrecovery-twrp-2.8.5.0-LT26i.img", hope I did the right thing this time, hahah. Thank you again for your help !

Glad that it is worked for You. Yes, You did somethings wrong, which caused You bootloop, better explained as below:
1) The "stock-6.1.A.0.452-twrp-2.4.0.0.elf" is the stock kernel of ICS version of Xperia S. So if You flash it with a ROM, Your ROM won't boot.
See, each ROM consist of two main parts, one the kernel and other the is the remaining of ROM(apaps, data etc.) A ROM is compatible only with certain kernels, and if wrong kernel is used with a ROM, the ROM won't boot. This is what You were doing, using a stock kernel on non stock based ROM.
2) This essentially doesn't lead to boot loop. This step needs to be done sometimes if You occur a error while flashing ROM via TWRP sometimes.
3) Yes, this sometimes does cause issue, the procedure is always for a clean flash, -Wipe system, wipe data, wipe cache and wipe dalvik cache. Flash ROM and immediately wipe cache and dalvik cache.

3) Yes, this sometimes does cause issue, the procedure is always for a clean flash, -Wipe system, wipe data, wipe cache and wipe dalvik cache. Flash ROM and immediately wipe cache and dalvik cache.

I guess You are on stock firmware and flashed the "stock-6.1.A.0.452-twrp-2.4.0.0.elf" or the twrp.img file via fastboot directly. Flash the DoomKernel from here via flashtool as kernel and it will work with stock and have recovery too. Use the blue coloured "Download Now" button and the extension of file is .elf.
