[SOLVED] Am I bricked? PLEASE help me :(

Hi guys. I'm quite a noob, but have a good experience on flashing without be bricked (CM9, CM10, Crash, Paranoid...), but I have a problem.
I will explain to you step-by-step what I've done with my Note, so I wish some of you could help me.
1) I was running JB Crash ROM with PhilZ kernel.
2) Some apps got Force Close too often, so I went on Rom Manager and, after a look into the "Fix permissions" description ("It will fix some force closes" or something like that), I decided to give it a try and I tapped on it.
3) After that, my homescreen became unusable, because "TouchWiz Home" got EVERY TIME force closed without reason. Everything else worked fine, so I deciced to boot into CWM recovery to restore a nandroid backup of the same ROM.
4) Instead of tapping "restore", I tapped "backup" (my fault) and it started without possibility of get back. I got something like 200 Mb of free space, so in every case it will never have had success. My Note stucked at this point, so I decided to reboot manually (vol up+home+power) into recovery. Finally I tried to "restore" but I get this message: "ERROR WHILE RESTORING /SYSTEM".
5) I tried to reboot my Note, but it stucks at "Samsung Galaxy Note GT-N7000" screen without going on.
The good news is that it can go without problems into recovery and into download mode. What can I do? Flashing from CWM, for example, CM9 can fix this?
Please help me thanks!

1. Boot into CWM
2. Wipe data, dalvik and cache
3. Format system
4. Reflash your ROM
Don't use rom manager it's not compatible ....

After formatting /system, can I try to restore my nandroid backup? Or I have to necessary reflash my ROM? In that case, it's the same thing make it via CWM or via ODIN PC? I'm still on PhilZ recovery, which is safe I guess!
Anyway, thanks for your help

Via CWM or Odin, depends if you have your rom in the zip or the md5.tar format.
I would reflash to be clean. It's a bit more work in restoring your apps and data
afterwards, but at least you don't restore any messed up files.

if you can still access CMW and Download Mode then you probably are not brick... try fresh install through pc odin.. safe method no need to worry about bricking by fullwiping on unsafe kernel or raising triagle or binary counter whatsoever.. if you wanna play safe then PC ODIN and after that you can root your rom

Thank you guys, now I'm on stock ICS flashed via PC Odin and everything works fine I knew I was 99% not-bricked (still recovery and download mode avaiable), but I was a little scared too.
Thank you again!

glad you solved it.. :good:

[Q] [HELP]Xperia T Bricked

Alright, Here's the scenario : My phone was working fine, I tried installing the DoCoMo SystemUI here and the All-in-One add-on, Installed normally, cleared cache & dalvik, rebooted, the boot animation plays for a few seconds, it freezes and then the phone restarts. I tried clearing data, then re-installed the JB rom, then i cleared System, Data, Cache, .android_secure and even SD Card (basically everything except ext. SD) then installed CM10.1 from recovery and still the same thing, Bootlooped at boot animation.
And the phone won't charge offline normally, it charges for a while (like 10 seconds) then it starts itself and get into the bootloop.
As formatting everything and installing again didn't help, I don't think FlashTool will, but I'm downloading the 9.1.A.1.140 FTF now and I'll try it tomorrow (slow internet).
Is it possible that the phone is hard-bricked and can't be rescued? If not what else can I do to bring it back to life?

If it was hard bricked it would not boot at all, it would be totally unresponsive (Just like a brick)
Were you on cm10 before?
If so you you cant install those stock based add ons, you should be able to restore your backup. What happens when you do that? (You did make a backup didnt you? Always backup just in case it f**** up!)
If you were not on cm10 before then you need to have an unlocked bootloader to flash cm10, make sure you have unlocked.

I don't have a backup, but would it matter because it only backs up data, system, cache, and .android_secure and I formatted all of them and did a clean install of both official JB and then CM10.1, Same thing for both. That's why I'm scared, I did a clean install but it still bootloops. (OFC my BL is unlocked)

You have yet to tell me which rom you were on, informtion like that will help me help you. Please answer all my questions
which kernel is currently installed on your phone?

YES! FlashTool has fixed it!
And I was on stock rom and DooMKernel at the moment of installation.

CWM Recovery Won't Install

I'm following this tutorial on how to root my Orange UK GT-I9305 LTE Unlocked phone running 4.1.2.
Everything goes fine with Odin the phone reboots, then I unplug and turn off my phone, and boot into recovery mode only to find it hasn't installed and Android system recovery 3e is still there.
Any ideas what I'm doing wrong?

Not flashing as instructed is the usual .Like unzipping the file or wrong file faulty file download .
Try another recovery.

I did follow them to the letter, does installing CWM Recovery actually root the phone or is "rooting" the phone a different process entirely that's required for installing CWM Recovery?.

I initially had a rooted stock ROM that i was using for ages then upgraded to a custome ROM but for personal reasons decided to go back to stock.
Loaded stock ROM with intention of rooting only to get rid of bloatware, but not one of the ODIN Flash recoveries work at all, not one, so like you ended up using CF Auto and that worked but now im still stuck with Stock Recovery. I dont understand why none of the recoveries flash when they did before.

trouble with cwm/ twrp
Hi all. Yes I'm a noob and I wouldn't ask If hadn't tried a plethora of ways to install either cwm or twrp.
It took me a good hour to find this thread so hope I'm in the right place.
Ok I used odin to root and cwm didn't stick so still on stock rec. However I used framaroot to get super su working and titanium says I'm all rooted up. Other apps only for root also work.
I've since tried using goo manager and Rom manager to install cwm or twrp and both say unsupported.
I've searched these here threads and found a few with same problem namely when using odin cwm wont stick and android reinstalls stock recovery.
So I'm a bit stuck, I'm rooted but have no cwm or twrp.
Any help would he much appreciated.

Try Philz recovery .

I have never used a custom recovery on this phone but i think i read somewhere that when flashing by odin the thing to do is not let odin reboot the phone. untick the reboot option. then when odin is done flashing and says pass shut down the phone . dont let it boot up.once phone is off you can boot into recovery by vol up+hom+power Here is the tricky part. as soon as you see the white samsung start to load aka bootloader screen release the power button but continue to press volume up and home. you should see the circle with the hat symbol. and enter into clockworkmod once in clockwork mod you will need to wipe data cache and dalvick DO NOT WIPE SYSTEM then flash a custom rom zip that you have previously copied to either your extsdcard or sdcard0 at the same time you probably will want to flash gapps as well. the thing is if you boot up before entering recovery . the default native recovery from samsung will take its place back. maybe it is easier to just flash rom manager in the play store. flash clockworkmod and then boot into recovery from the app itself. I9300 is supported . dont know about I9305

thanks !

Thats exactly how I understood the cwm not sticking problem. I have tried rom manager and said not compatable with my device as did goo manager for twrp. I think odin is the only way I get it to stick. So il flash in odin and il try to get into cwm as it boots and wipe those two files you mentioned.
But then can I just boot up as normal ? or will android try to reflash its stock rom ? Damn my phone for being so difficult
I only ask because I haven't decided what CR to use yet (or even looked for any). I was gonna get it all ready first then learn how to install a CR - 1 thing at a time i thought.
Anyway thanks for your help :good:
JJEgan I found Philz thread to be helpful but something I feel Im just not ready for. Im new to this and although the updated cwm looked cool there were just to much going on, maybe for a later day.
Thanks all the same :good:

wiping data plus cache plus dalvick cache is done to prepare your phone for the custom rom that you are going to flash. the wiping is to clean those partitions because if they are not erased you will have problems. especially if you go from one android version to another or touchwiz to aosp. it is done so you get a clean install with minimal issues. if it is not done you will most likely bootloop. effectively it is a factory reset. all of your apps and app data will be gone so you do not want to do that unless you have backed up your apps . however sometimes google automatically installs them after you sign in.
I am not sure why clockwork mod does not stick but if you copy the rom you want to your phone install clockworkmod with odin and then use clockwork mod to flas the rom and gapps package then factory reset you will not have the stock recovery anymore. but this has to be done without booting into android stock . PLEASE FOLLOW THE FLASHING INSTRUCTIONS TO THE BEST OF YOUR ABILITY. AND UNDERSTAND ANYTIME YOU FLASH OR MODIFY YOUR PHONE YOU VOID YOUR WARRANTY AND POSSIBLY CAN CAUSE IRREPARABLE DAMAGE. BEST OF LUCK!

HERE IS SOME VERY GOOD READING http://forum.xda-developers.com/showthread.php?t=2362743&highlight=philz+recovery http://forum.xda-developers.com/showthread.php?t=2344125

think I got it lol
Ok that's sounds good. However I've just read the threads you linked and now I've got to back up my imei and NV files first or il loose them when flashing. The procedure is all there and seems doable for a noob but i read some peeps are having trouble just doing that. I really wanted to root/install a CR regardless of the troubles cos I want full access and more importantly want to learn all the ins and outs so I can get the best use from my phone so glad I found this forum cause I'm sure I would have bricked my phone otherwise.
Might I ask if I've got this right tho?
1: backup imei/NV files
2: use odin to get cwm to stick using your method
3: boot into cwm to wipe data/dalvick cache and gapps
4:use cwm to flash a CR
5:factory reset
I think that's right?

Thank-you for all that,I really appreciate it.
Can I ask the difference between the apps nandroid manager and titanium? I've backed up with both and wondered if i really needed to? The nandroid backup was nearly 3gb!
Also I was gona backup with qpst for imei and NV files but then read its only for US versions? Will the backup of efs folder include those?

honestly i really dont know what the differences are. l do not use custom recoveries or custom roms. i dont use titanium backup .Any rom I flash i get from sammobile.com. one reason i do not use custom roms is that none can support mhl. I use a monitor and bluetooth mouse and keyboard . without mhl I cant mirror my screen so i always stay with stock roms. i use Xposed framework for modifications.

[Q] Bootlop after failed wiping data [Solved]

Hi guys, i need your help..
I was tried to install a custom ROM and i use CWM v6 to install it (i'm on stock ROM | JB 4.3 | FW .205 | locked bootloader | recovery installed : CWM & TWRP), first step i format the /system and is successfull, then the next step wipe data/factory reset but i get stuck process on:
--- wiping data ---
clear /data done.
clear /cache...........
I don't know why, but i've been waiting for 20 minutes and still stuck like that than i decides to turning off the phone with tiny button at bottom of battery (not power button), i turn on the phone again and then i've got bootlop ( what.... where is my recovery ) i didn't noticed the recovery still in there because there is no LED notify when i turn on the phone, just SONY logo :crying:
Is that happen because wiping data didn't completed and causing my recovery also gone ?
So what should i do ? can i get the phone back again ? I have the stock ROM backup on my sd card and on my laptop because before i try to install a custom ROM, i've created current ROM backup with CWM.
please help me guys..

You wiped /system so your recoveries are gone.
On older Recoveries using the wipe to install new rom can take ages so just leave it and eventually it will finish, latest version of Philz (in Bagyusz/Nexus ROMs) seems to fix this issue.
Use DSSMEX triple recovery and use philz not cwm as its a much nicer recovery (but the clean still takes ages as its an older version)
Use flashtool to flash stock rom and start from scratch to re-install custom rom.

You have bootloop because your phone is essentially empty of any OS or recoveries.
Flashtool to stock, find dssmex triple recovery and install that in stock when rooted, load into Philz, clean to install a new ROM and then just wait, it will take a while usually dont worry unless it takes over an hour.
Then flash the custom ROM of choice.

Can I know what Custom ROM are you trying to install?
Sometimes wiping could take time, and I am not sure why. If happens again in the future, just let it be.
As you are using LBL, I am unable to elaborate nor understand how recovery has gone. (WARNING: FOREIGN LANGUAGE) Recoveries for LBL are stored in the ramdisk OR the FOTAkernel. This is due to the fact that Xperia SP does not has an exclusive "recovery" partition in the rootfs. I dont know if wiping data would trash them.
You can easily recover your phone by flashing a stock ftf. You may follow this guide: http://forum.xda-developers.com/showpost.php?p=56717587&postcount=4

Soft brick on rooted Xperia Z3c locked bootloader?

I have Xperia Z3c 5.1.1 rooted with locked bootloader. It is on wifi only. Yesterday I've turned wifi on and suddenly have got device off. I tried to reboot. I see the Xperia logo and bluish Xperia start screen with waving elements. However, the home screen and apps are not appeared, have just black screen. The battery is fully charged (green led). I tried several times reboot today as well with the same result. I believe the phone is soft bricked.
The phone is rooted with NDR Utils and TeamWin Recovery (TWRP). I also have Titanium backup.
After reading this forum I found several ways to unbrick the phone:
1. Soft reset (Power + VolUP) up to 1 vibration.
2. Hard reset (Power + VolUP) up to 3 vibrations.
3.Use flashtool (flashmode) and flash ftf file. Should I flash Kernel as well?
4. Use phone System recovery (Power + VolDown).
Which method I should try first? Can I save root and my current Lollipop firmware or I should go and start from the scratch with rooting and flashing 5.1 again?
Thank you for your suggestions.

Try soft reset and hard reset. This don't break your phone but it is worth a try. If this will not work do NAND backup (full backup of phone) in recovery. Now you can try clear cache in TWRP (wipe -> advanced wipe -> check cache -> swipe to wipe). If this don't work try clear dalvik/art cache.
If this metods didn't work flash same rom (if rom was't pre-rooted root after flash). If system starts you can restore NAND backup without system partition and cache.
If system don't start after restore backup the last chance is clear rom flash.
I don't know where the problem is but in my place I would do that

Thank you krzysiek546 for your help.
I have tried soft and hard reset, both unsuccesful. I made backup and wiped cache and dalvik from within TWRP. The phone after apps optimization has started the system (there was black screen but I was able to see home and Back buttons, which were non-functional, i.e non-responsive.) The screen became black again after a few secs and did not return to the life then.
I think I'm going to flash the Rom. My question is there is any chance to get brick again in case I will restore from the TWRP backup (if there was a virus or something?). May be I should wipe data, cache and dalvik and only then made a backup?
Also, when you saying "a clear rom flash" as a last chance do you mean factory reset?
Thank you.

Don't wipe data before backup. This is like doing backup after format system. It doesn't make sense.
Have you tried this metod with flash with nand backup and flash same rom (zip from twrp or ftf from flashtool) and restoring data without system partition (it's important)? In this i mean something corrupted system files. In this metod you can save your data. You just reinstall system and restore data from nand backup.
When I sayed "a clear rom flash" i mean wiping all data in recovery and flash rom from flashtool or twrp without restoring anything. You can do it first. I think now it's beter because you can check did that fixed your problem and if this "clear rom flash" repair your problem you can restore data from backup.
As to your question. Yes you can get brick from restoring data from twrp but in my opinion this virus or something must have root permissions to do this.

After installing the newest supersu, I also get this bootloop. Is there a chance to undo this without wiping data?
Edit: ok, after hard reset, flashing SU, cleaning caches etc. (which all did not help) I reflashed the ROM, now it works again. Pheeew.

When I had that error, it was still V2.80 and no update round the corner.

Thank you for the link. Worked great for me. Installed per TWRP.

Well, in my case I didn't updated SuperSU, just have turned on wifi. I think the problem may be in Wallpaper app I have installed previously. It changes wallpaper every day, but I noticed sometimes the background of my home screen where all apps are became black.
Anyway, only "clear rom flash" with wiping cache, dalvik and data helped me. I then installed pre-rooted Lollipop ROM I made before and restored all custom apps from the Titanium backup. BTW, don't try to restore system apps from the Titanium, I've got the error with Xperia keyboard and have to make a restore whole system from TWRP.
