Hey, i was going to install cyanogenmod and rooting it. downloaded all the files then the cyangenmod failed, had to restore phone and it only booted in recovery, then i dide full wipe on phone. Now phone will not start it's dead, won't start in recovery either download mode. I need HELP!:crying:

Read this link carefully and try everything it says.. http://forum.xda-developers.com/galaxy-s2/general/guide-t2345831
Its to bring your phone to download mode and to life again.

No, it's not. Have you even been through the thread yourself ?
There is only one thing in that thread that might (and it's a very big might, like a 1 in 10,000 chance) help a phone that won't boot/no download mode or recovery, and that's the 'jumpstart' method. And I can count the number of people I've seen this work for in 2.5 yrs on one hand. Same with a jig, almost certainly won't work but try one if you can get one.
Motherboard replacement is almost always the only way to fix this, assuming a JTAG can be attempted at no cost if it doesn't work; JTAG's almost always won't work in this situation either.

New here and need some help

Hello,
I reciently rooted my samsung galaxy s2. I tried a few roms so i could get used to the system or restoring etc. However i encountered a problem whilst having a peek at an alpha jellybean rom, where i noticed that my CWM app on the phone had vanished? I attempted the restore using the 3 button combo and found that i kept recieveing E: can't mount/ E: can't cache messages whilst on the restore screen. i could find my latest restore on my sd card however it wouldnt restore. I believe the CWM was removed from my phone which caused it to not work. I was then stuck in a bootloop. no matter what i done, boot to a stock rom via odin, try the different CF roms i and try to put CWM back on to the phone? I read a post on here from someone who had the same problem, who was told it looked as though there is a problem with the partitions. i followed a tutorial and used odin to put Latona 20110114.pit on the phone. it said i would get a blank screen once this has done and i needed to remove then place the battery back in the phone then put it into download again. This didnt happen!! I done as instructed and now my phone wont go into recovery mode, download mode or even boot loop. I fear i have completely bricked my phone so i am trying to use oneclick heimdall to sort it however my PC keeps saying i need admin rights to install it which i have.
Can someone please help me out. I am new to this so please go easy on me.
many thanks
If you have no signs of life from the phone, it's probably cactus.
You might as well try a jig (but unlikely to work; still try one tho). Only option is service centre & hope they can't tell/don't care you've been messing with it & fix it under warranty or JTAG repair by a 3rd party repairer, at your cost obviously; will be cheaper than having Samsung/an authorised repairer fix it if they refuse warranty service which they're quite within their rights to do.

First result of searching suggests that's meant for the I9003. Good job.
HA
Hello,
Awe well then. never mind eh, whats done is done! Its totally bricked so i thought i would chance my luck by sending it back to O2 for repair. I was reading the only other way to get the phone running again was to take it to bits and hook it up for some stock flashing. so heres hopping they sort it!
lesson learnt!!!

[Q] odin failed, flash recovery.bin cwm

i was trying to root a phone for someone and after odin completed it said it had failed.
the phone is a telus samsung t959d running froyo.
I followed the instructions from (I would post the url for the link but i am not allowed to.)cyanogenmod's wiki, after it failed I rebooted the phone and it got stuck on the screen in the attached pic. I have tried to boot back into download mode to no avail. From the screen it's stuck on I cannot get any tool to register the device as being present, adb, heimdall, zdiag, etc... I even tried fastboot out of desperation.Before I used odin I tried to get the phone to boot into the bootloader but it only ever went to either recovery or a normal boot and I tried every button press combo I could think of and found and nada.
Even running adb reboot bootloader just made the device boot normally. I think that if I could get it to boot to fastboot usb i could then try fastboot. I am new to rooting devices and have successfully rooted my HTC EVO3D and got s-off and simlock removed for any carrier. So I do know how to follow instructions properly, why flashing the recovery.bin failed I don't know and every fix I seem to find says BOOT TO DOWNLOAD MODE. if I could do that I wouldn't be having this problem lol. Anyway can someone please help me figure this out. Thanks. ANd if you need any further info please let me know. I don't want to have to give my friend my phone due to a software issue.
And YES I did pick PDA not anything else.

I kept reading other threads and sadly I din't pully the battery first before disconnecting the usb and repartition may have been checked as I see that it does the as default for my version. Also i turned off ODIN as I was hoping a reboot of my computer might help. I will keep trying to find an answer till someone gets back to me. this post may not even show up if I can't do a second post if no one has replied first.
Everyone was a nub at one time wasn't it FUN hahahahahaha sob cry

I tried a jig and that didn't work. There must be some way of getting the device to give up on completing a task i no longer can give it due to ODIN being shut off.
Why is it that the "how to root/unlocks" never have the "if x fails then do these steps etc..." Had the how to had "pull the battery before disconnecting USB and don't reset or shut off ODIN" I wouldn't be in this mess. I realize that it's user beware but a few important steps like that in case of a fail would go a long way to you guys not shaking your heads. Instead of "silly nub hahahahahaha". No offence but I get that a lot and try to remember that when I teach someone how to use a computer. I am new at phones not at everything.
Further Developments Please can someone help?
I was giving someone a new memory card and they had a Samsung SGH-I896 it has an EB575152VA battery and the one I have the T959D has an EB575152VU battery. I exchanged my battery for hers by accident somehow and when I plugged my phone in it didn't go to the phone triangle computer logo screen it booted to recovery and said it couldn't charge the battery and kept rebooting to recovery. I got my battery back and it booted back to the phone triangle computer logo again. Grrrr....
The other thing I saw while the recovery screen was an error message that said
Code:
E:/data/fota not accessible
(may not be 100% accurate I don't have the battery to check right now but can get it again if need be) anyway I now see that there may be some light at the end of the tunnel. i have the correct stock firmware for the device I tried flashing it while in recovery but the phone kept rebooting before anything got done. My question is how can I get the dang phone to stop asking for Odin and go to recovery so I can flash stock firmware and ROM back to it? As I cannot as far as I know give it what it wants because I reset Odin and nothing seems to see that the phone is connected to the computer. I am going to try the other battery on a full charge to see what that does.
I am new at all this and want to get it fixed. I cannot afford to send it off to a service center and besides that I want to do it myself as I want to become a developer and droid technician. I would gladly donate to anyone but am still trying to get Google to accept my pay-as-you-go credit card and I don't have PayPal either. Which is really frustrating when it comes to giving back. I posted a Q&A on how to without PayPal or CC but as of the last time I checked no one has gotten back to me about it.
The CyanogenMod guide is flat out WRONG. I've tried to change it, but anything I do is reverted in an instant. I also tried to use it to install the ROM only, ended up bricking my phone and it took me hours to unbrick. That's how I became acquainted with XDA.
So, to get this straight:
1. you're using the stock USB cable
2. you remove the battery
3. you hold volume down
4. you plug in the usb cable
5. after a few seconds, you release volume down
6. the screen does not display a yellow triangle with an android

That is correct. If you think that my idea below is a bad one or if I downloaded the wrong firmware package please let me know and /or you have a fix that will work? ty
I have though come up with an idea that may work. I am going to charge the "wrong" battery in erm the right phone lol and then use it to trick the device into booting into recovery instead of the cellphone triangle computer (CTC, for want of a better acronym) The I896 battery ends in a V not an ? (sorry can't rem don't have it on me) from the I896 model I think it is, plugging it into USB with the power off sends it to recovery with the "battery cannot be charged " message instead of the CTC screen.
I tried it but the charge in the battery was too low and rebooted. I am hoping that with a full charge (as long as I don't power on the phone first as this will make it go to CTC logo again.
I am hoping that I can install the update.zip that I made by first unzipping the T959UVJFD_firmware.tar I downloaded then unpacked and then repacked into an update.zip as I don't think that it will read the package as a tar file and if it's not called update.zip The recovery is still stock. If I get the phone working I am not going to try unlocking and rooting it again. I will just post two separate adverts one as a carrier locked device and the other one (higher of course to cover buying the unlock from Telus) as carrier unlocked and then I will buy the unlock code if the blah blah you get the drift. sorry for rambling on.
oh and I can't rem if I said this or not, In recovery it "E:/data/fota not accessible" I don't know what that means yet I have been busy with other things and haven't looked it up yet.
Since you can get into at least some version of recovery, your bootloader is intact and you should be able to unbrick it. You ought to be able to get into download mode using a download jig. You can get one on ebay for a few bucks or you can make one yourself. There's a guide floating around here somewhere that lets you make one from a microusb cable.

Phone won't start after flashing in Odin...

Hey guys
1) Restarted my phone today using CM10.1 from a very recent nightly (within the past week).
2) On restart, phone froze and got kernel panic.
3) Restarted into CWM and tried to do a restore to an earlier backup I had made.
4) Half-way through the restore, I got ANOTHER kernel panic (never had that before)...
5) Only things I could do with the phone after that was enter download mode...nothing else...couldn't enter recovery mode anymore.
6) Went into download mode and flashed this CWM-Recovery (http://forum.xda-developers.com/showthread.php?t=1118693) and followed the instructions to the letter.
7) Odin 3.07 hung on NAND Write Start
8) Tried using Odin 1.3, and it seemed to flash correctly. It says completed no errors.
Phone will now not even start and is completely unresponsive...pressing any combination of buttons will not start the phone, and the phone is not recognized in Odin anymore...did I just hard brick it? Any other ideas?
Thanks,
Elliott
Service centre. Although if you can have someone who does JTAG's have a look at it to determine whether it can be JTAG'd without you giving them any money up front (I.E you only pay them if it can be JTAG'd), try that first.
Thanks that's what I thought.
Also, try a jig if you can get one. In all likelihood won't work, but stranger things have happened & you have nothing to lose.
Yeah thanks that's what I plan on doing. Any idea what I did wrong, though? I don't want it to happen again if I get it working with a jig.
Impossible to say. Not sure why you flashed that nondescript kernel/recovery in that situation tho given it probably wouldn't have worked even if the flash had been successful (You would probably have ended up with bootloop given recovery was obviously 'broken'). I would have flashed stock with Odin (And that's certainly what I tell people in your situation on here to do because it normally works).
But flashing recovery rather than a stock rom probably didn't break your phone, put it that way, so you didn't do anything 'wrong' per se. Just remember if you get into a similar situation again, go back to stock via Odin & start again (re-root your phone/restore a backup, flash your custom rom/kernel again, etc).
If the jig works (and don't get your hopes up or anything, we're talking a 1 in 10,000 chance, and that's probably being generous), flash stock with Odin (you wont have much choice).
Well...brought it to a JTAG specialist today and he couldn't fix it either...says it's very rare and he's had 5 out of 80 S2's like this happen without being able to fix them...
Bummer. Motherboard replacement in that case. If the phone's under warranty, take it to a service centre & say as little as possible. You might blag it for a warranty fix. No warranty ? You can still have a new motherboard put in by a service centre (more expensive option usually), or you can source a 2nd hand MB from a 'donor' phone (one with a broken screen that's otherwise OK, etc) & either swap it in yourself or pay a local mobile repair shop to do it (usually cheaper option).
@ OP By following what you flashed I noticed the date, we're talking about a 2 years old thread, a lot have changed since.
Not sure that was what bricked your device but I get that panic mode.
The other thing that it comes to mind is nand corruption, which has been quite common these days with people running custom.
I'm with bungle there, the best recovery package is going back to stock and start fresh.
I, on the other hand, wouldn't accept the situation you are on, I would spend a whole week trying to get that phone to boot again, whether a second opinion on a jtag, a new jig, another battery or any other thread on here at xda.
If the device gets hot near the rear camera and it won't even charge nor get warm around that area dismiss what I just said and proceed with the mobo replacement bungle suggested.
And of course, if you did something else to your device and didn't share it please, come clean so others don't freak out by reading this.
Sent from...this is not even my S2
Hey
Nothing else was done to the device...just what I stated exactly.
I caved today and bought a BNIB S3 because I couldn't go without a phone anymore...
Thanks for the help, guys

[Q] Repair shop killed my phone ?

Hello,
I have a Samsung Galaxy S2.
After reading this post http://forum.xda-developers.com/showthread.php?t=2382579 I decided to root my phone.
So I went ahead and started with this step http://forum.xda-developers.com/showthread.php?t=1118693 because I was unsure if I had a kernel with the MMC-SUPERBRICK-BUG.
After I flashed CWM-SuperSU-v0.97.zip using Odin version 1.85 and after the phone rebooted it was stuck at the "triangle screen" for a few seconds then the display went black and I couldn't do anything further.
Up to this point the phone was still accessible in download mode (volume up, power and center button). I believe this is called "download mode". Sorry but I am a complete noob with rooting phones, etc...
So I panicked and took the phone to a repair shop (big mistake). The guy ran it in download mode then tried to flash something onto the phone (I think he used all 4 fields: Bootloader, PDA, Phone and CSC.
Then, in the middle of the operation, Odin froze when writing "setting up connection". Then the phone died ! pressing the 3 famous buttons does nothing and the phone just stays dead.
I had to leave the phone there as the guy said they will try to bypass stuff and try to connect to the CPU directly (sorry again if this sounds noobish). I did update my modem firmware and my computer BIOS in the past... but I guess this one was more complicated.
At the shop, they asked me to check again in 3 days. I am lost here. I don't know what to do anymore.
Is the phone hard bricked ? Should they bear all expenses for what they did ? I would bring back my phone and try something like this http://forum.xda-developers.com/showthread.php?t=1878255 or even a stock flash but I am afraid I cannot do that as the phone isn't even powering up anymore after they tried to repair it at the shop.
Any advice is appreciated.
Nope. You borked it. You tried to flash custom firmware to the phone & obviously failed spectacularly at it. Instead of trying to flash it yourself via download mode (which you could easily have done unless the NAND was borked), you paid them to do it. Sometimes flashes go bad. Sounds like that's what happened in this case.
Reading between the lines they sound like they're going to try & JTAG it (or have someone else do it). And if that fails I presume they'll change motherboards. You could always get the phone back & take it to someone who does JTAGs if that shop doesn't themselves.

Yes I know I failed at it
Or maybe the shop technician is the one who broke it. At least when I had the phone with me I was still able to boot in Odin mode.
Do you think I could have recovered my phone if I had kept it with me and it was booting in download mode ?
I feel so pissed that I took it to that shop. I just wish I hadn't panicked and I had tried, instead, to fix it at home by asking for more help.
Anyway I still haven't paid them anything so far.
We agreed that they will pay for the motherboard because I brought in a working phone (that would power up at least). The owner of the shop was nice enough to agree that he would only charge me fees for installing new software on the phone (even if they have to change the motherboard) because he knows the phone was booting in Odin mode when I came in to the shop and his technician flashed the wrong firmware.
I also wrote down the board serial number so I can be sure they changed it (if they say they did that). So you are telling me the phone can still be fixed ? What does JTAG mean ?
Even if it is fixed I think I will be too scared to try and root it again. Unless I can understand in advance, step by step, what I need to do and what file version(s) I need to use.
Ok, I got my phone today in good working condition.
According to the shop, they had to replace an IC (I don't know what damaged the IC, I am assuming this happened when they tried to electrically jolt the phone) then JTAG it to get it to work again. They charged me a small fee (and they did end up bearing more than 50% of the expenses) because I brought in a phone that was booting in download mode and they take responsibility for what happened after that (flashing wrong files which caused the phone to completely stop booting).
Anyway, long story short, this was my first attempt to root a mobile phone and I learned my lesson.
I am running the following:
Model Number: GT-I9100
Android Version: 4.0.3 (which I will need to upgrade to 4.1.2 of course)
Baseband Version: I9100XXLPW
I know you will say read the sticky posts or the guides but the truth is, that's exactly what I did (you can see the links to the guide I tried to follow in my original post) and I still ended up failing at rooting/installing cyanogen on my phone right after installing Clockwork Mod.
The truth is I am scared to try again and mess up the phone. So this time I would rather be safe than sorry.
What can I do, this time, to safely root it and install a mod like Cyanogen.
Detailed steps are appreciated:
- Do I need to upgrade to 4.1.2 before rooting as 4.0.3 might have the superbrick bug ?
- How to backup the phone.
- Odin version to use, ClockWork Mod version to use, Cyanogen version to use
- How to connect the phone, how to reboot in download mode and all the necessary actions to avoid bricking my phone.
No spoon feeding aloud on XDA.better to read and learn how to do this and that but before you flash anything after learning how to do that learn how to fix it if it doesn't work. :thumbup:

Fair enough, I figured I'd get that reply from someone and it's normal to be honest.
I decided not to try anything on my phone before I re-read the guides and be sure I know what I am doing.
I will also keep the phone running on stock firmware (after upgrading to JB 4.1.2) to check the battery consumption behavior which, I hope, will be fine since someone tampered with my phone's electronic components at the shop.

[Q] Hope someone can help

This may turn out a bit long...
My s2 has been playing up in one way or another for a few months now such as freezing, turning itself off and kept going into drive mode by itself then last week all my messages deleted and I couldn't send or receive any more and then the next day it turned itself off and I can't get it back on properly. It turns on, goes onto the Samsung Galaxy S2 screen then onto the O2 welcome screen then to the screen with the flashing S then just goes between that and the O2 screen over and over again. Been looking for help the last few days and the main thing I could find was to go into recovery mode and restore it but I can't do that because my home key doesn't work. So nor could I do the second thing I read could help which was to go into download mode and flash it. I didn't even know anything about recovery mode, download mode, flashing, rom, odin or anything else until last week. My phone is exactly as I bought it. I then read about a usb jig which would force it into download mode which I got today and it didn't do anything. I actually couldn't care less about the phone, I would love to just smash it to bits! BUT is there any chance I will ever be able to do anything get it back on just once so I can get my photos and videos off it? I've connected it to the computer but it comes up as an Android Modem so that I can't get the files off that way and it won't connect through Kies either. I know sending it to be repaired would end up with it coming back totally wiped so no point doing that. I normally wouldn't be so bothered it's just there's pictures of my daughter's first birthday and holiday and videos of her first steps. Is there anything else that can be done? Thanks.
There's a 0.000001% chance the phone will boot normally & your stuff will be intact if you can get into download mode & flash a one part stock rom. The more likely scenario is you'll need to flash a 3 part rom which will wipe the device.
You could try ADB to get into download mode, but you're going to need to be motivated to learn how to use it (plenty of tutorials on XDA/elsewhere; search). If that doesn't work for whatever reason, try fixing the home button.
Being a former betting man though, I don't like your chances of recovering data.

Thanks for replying. I don't have a clue what a one part or three part rom are sorry! Doesn't look good then. I'm so annoyed. I had planned to sort through my files and get them backed up last weekend because I knew this would end up happening and the stupid phone died on Thursday! I don't think fixing my home button would help because the volume button didn't work much either, it's a wreck to be honest! Had a quick look at ADB, looks complicated but I'll have a proper look later on as a final hope otherwise I'll just have to accept my files are gone for good
Just an update...tried to get into download mode with adb but it doesn't find my phone. Is this because it only comes up as an android modem by any chance? Think I may have to give up hope. At least I will learn from this and back things up a lot more often!
