Did I brick my phone?

Okay, I was on CM7.0.3. But I wanted to test some other rom (Jokerdroid 4.2).
Now I did like this using clockworkmod 2.5.0.7:
- Boot into your phone’s recovery mode. You do that from ROM Manager
- Select ‘Wipe Date/Factory Reset’, then do ‘Wipe cache partition’
- Now go to ‘Install zip from SD card’ and choose the zip file of your ROM
- Reboot your phone
So after i did all of this, i rebooted but some error showd up. I was like okay, i reboot again for a test, but now it doesnt do anything. If i press on the power button doesnt boot, same for power + volume button.
Did I just F*** my phone up or ?

SHOULD NOT BE BRICKED,
try to pull battery out and then boot if not do NAND RESTORE
P.S did instalation finished of jokerdroid and what error you got

oh lol okay, im restoring now!
And ye the instalation was finished from Jokerdroid. Can't remember what the error was. But I think it is fixed!

Happy to see you solved...

wel ye i wont say it is solved, i did a restore but when i boot it show the htc logo and doesnt do anything after it.

before restore also wipe data/cash and then restore

Thank god Its working again!
Would there be a big chance i will have the same error again if i try to install Jokerdroid again ?

dont realy know sice dont know what error did you got,try if fails do a NAND RESTORE again

I once forgot to wipe cache and data before flashing, rom installed without errors but wouldn't boot. I had to wipe then restore the backup and then wipe data and cache again before attempting to flash the new rom again, it worked perfect the second time.

[Q] <URGENT> Phone Dead! :'(

Hey guyz!
Well, Here's my story
I unlocked the bootloader of my Arc..... Flashed the 0.42 rooted .ftf file and well I had my arc.
I took backup of all my stuff and thought of installing CM7.
So well, I downloaded the latest CM7 Mod from the website stable one and fastboot'd (or whatever the language is) the boot.img into my arc.
And den I booted my phone into recovery mode, wiped my cache, system and data and flashed the update_cm7.1.zip file into it.
Not my phone after booting up dosent work. It shows the lock screen and within a second boots again :'(
I searched and found that I did not install the CWM Recovery and guessed that it was crucial for it.
Now I have a dead phone.
Can you Pleaaaaaaaase Help Me out!
My mobile is my life and my parents will kill me
Thanks Alot!

Install doom kernel via fastboot
Enviado desde mi LT18i usando Tapatalk

Done Doom Kerenal
Still going into Infinite BootLoop!!

you usually wipe everything(user data, cache, dalvik cache) after flashing the ROM
or try repeating the whole process
- flash .42 ftf file using flashtool 0.6.7 then disconnect device
- fastboot flash boot boot.img(from the CM7 package) then disconnect device
- power-on and go to recovery then flash the CM7 ROM then GAPPS
- wipe user data, cache and dalvik cache
- reboot
I suggest you also try FXP105 package here in XDA, I think it's more updated than the one from official CM7 site

What are you talking about?
DooMKernel is for stock based ROMs, not for CM.
I'd recommend to you to check out FXP's CM7, it's way better and stable, imo.

Do that and follow these steps:

Connect your device with your current ROM to a PC.
Put the ROM (*.zip file) on your sdcard.
Shutdown device.
Connect your device with fastboot mode (pressing menu button) to a PC.
Go to your fastboot folder.
Press shift key, right click and select "Open command window here".
Install kernel by using the command "fastboot flash boot boot.img".
After installing disconnect your device from PC.
Enter CWM recovery by pressing volume down button several times while booting.
Do a full wipe/factory reset, wipe cache, wipe dalvik cache.
Select install zip from sdcard.
Navigate to the folder you've saved the ROM and select it.
After installing select reboot system now.

Now I got the same problem as Serebii. I've done all you've said, but I just get a black screen flashing the kernel. The fxp-Logo doesn't appear and I can't get into recovery mode.

Have you guys flashed .42 firmware before?
Or are you using a different?
You'd have to flash .42 firmware (look into CM7 thread) and then do the above steps again.

guys, when flashing kernel, look closely on your fasboot command window if there's something like "1 bad blocks encountered" message
should be "0 bad blocks encountered" for the kernel to work fine from what I know

Did That
Still Nothing...
Although Unlike macmeir, I'm able to go into recovery adn first see SE, and den CM7 boot logo
And also 1 second of the CM7 Welcome screen.
Thats It
Yea, It isnt showing any bad blocks

Now I got my phone back to life. I flashed the .42 firmware with flashtool. But then I had to install the fxp103-stuff. I cleared all caches, etc. It's strange; I did it before but it didn't work. I don't know if I've done something different.
But I'm still not able to run fxp104 or 105. I won't try again soon, because I spend five hours to get my device working.
Thanx for your help and good luck to you, Serebii.

good for you.
btw, you can also try Doomkernel on stock ROM, it's a great combo, I always go back to that setup

OK,
I flashed the latest CM7.2 And My Phone's alive Again!
A Biiiiiiiiig Thanks to Everybody!!

Ok if you can access recovery then get out the sd card and put it in another working phone then add few more default ROM-s and try them till it's boot.because maybe problem is kernel and you dont know what kernel is in there.
Or just try to flash an other proper kernel.

First of all, don't post questions in the development section, to answer your question, read the guides and stickys which should have been your first port of call.

no real need to put sd card in another phone.
just boot into cwm, goto mounts and storage. and look for something like mount USB storage.
and voila, your sd card will appear on your pc.
p.s try wiping /system from mounts and storage and flashing rom again

First if you want a custom rom on your phone, you will probably need a custom kernel ass well . Kernel is the bios for your phone and rom the OS. Go to the Rom thread and read there witch kernel is recommended for that rom. After flashing the kernel, go to CWM (Recovery) and flash the custom Rom and finally flash the wifi modules associated to that kernel.
CM based Roms does not work at all with stock kernels, they have their own kernels.
If you want a recommendation (for Kernel, Rom, baseband) look in my signature, you have links included !
Don`t forget the procedure for installing custom Rom (wipe everything : factory default, /system, /data, /dalvik) and only after wiping all install the rom.

Problems (assumed):
1. Locked bootloader
2. Didn't flash kernel
Fixes:
1. Unlock bootloader
2. Flash kernel via flashtool.

Install stock rom with flashtool (wipe everything). Root it. Install CWM. You should then restore whatever backup you have...

[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 !

Hello, and thanks for the answer ! After a few days using the Pure AOSP rom and rebooting several times without any problem, I just got a bootloop again yesterday, forcing me to reflash my rom to be able to use the phone again... will your method (including your tutorial in your signature, which I'm trying as I write this) solve the problem once and for all ? It's a real pain to redownload all my apps again and again and again because of those bootloops =(
Edit : finished following your tutorials, everything seems to work for the moment, hope it will stay stable this time... thanks for your help )

What did You do before the bootloop was caused? Did You try to flash the TWRP again?

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.

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.
