[Q] Booting Problems! [SOLVED] - Sony Xperia Z Ultra

For reasons unknown, I'm able to boot into flash mode and therefore restore my ROM.
Thanks for helping me though, random stranger!
So can anyone close this thread? It isn't needed anymore.
I recently flashed a new stock pure Lolipop ROM on my Xperia Z Ultra from a stock pure Kitkat ROM that I've been using for months now.
However, it is noteworthy that my device has been rooted and custom roms has been installed on this device for about a year now. So my device has its bootloader unlocked.
I followed all of the instructions I can
- Wipe the data and cache ( incl. dalvik )
- Flashing the ROM in question
- Flashing the su and GApps
- Wiping the cache ( again, just to make sure )
And here's where the problem started
When I started to boot my smartphone, it flashes red for a couple of times. At first instinct, I thought it was a battery depletion problem, and sure enough, it was! So I plugged in and noticed yet another problem; my phone started randomly turning on for a brief moment before shutting back down, presumably due to extremely low battery power. And it didn't even bother to wait for my Z Ultra to be charged to a reasonable level of power before attempting to power on. However, I tried using the power+up button fix, and it didn't work and then there's yet another kicker; Fastboot ( Blue LED ) Mode is no longer accessible on my phone. When I plug in while pressing down on my ZU, it does nothing and simply just charges ( presumably ).
I'm currently on my last legs of hope and doing the last resort: to wait for my smartphone to charge substantially enough for a long time.
Which is about 8-9 hours after this post is made.
TL;DR
- Device is currently rooted for a year now and has been installed with custom roms left and right.
- I followed the instructions to the T
- Phone not able to turn on
- When charging, phone attempts to turn itself on, regardless of power level
- Plausibly due to low battery level 15%-24% during flashing
- Fastboot Mode not possible presumably due to low power
- Now waiting it out for 9-8 hours to see if issue resolved
- Will update whether if method works or not
Please help! This is one of my most used smartphones.

Yeah, it might be the battery that's gone bellow the "zone". What I mean is when you deplete the battery completely to 0%, there's still more battery left, but the system shuts it down so not to damage the battery. It's a Li-ion thing. But once in awhile it does happen that it get completely empty, and you'll experience what you've done here. A dead device. It's not only Sony phones that experiences this, but from all OEMs.
Notes:
- So, keep it charging for 15-20 hours and see if it helps.
- You mentioned fastboot not working. Be sure to have fastboot installed on the computer. If it's not, it won't work.
- Blinking red LED also (usually) means there's been a kernel panic

I'll try to follow your advice on the extended charging thing.
Fastboot is definitely on my computer so ye
Kernel panic? What can I do to remedy that?

Just flash a different kernel. If that doesn't solve anything, then we'll know that it isn't a kernel panic.

We've got Fastboot and Flashmode. Fastboot is what you use when you want to flash some ROMs and kernels through a terminal (command line), while Flashmode is for flashing ROMs in Flashtool and Sony's PC Companion.
You can enter Fastboot by holding VOL UP while you connect your device to the computer. Remember to hold VOL UP until the LED above the screen turns blue. Once you've achieved that, the either flash/hotboot a kernel with recovery, like NUT's Dual Recovery, and then restore or flash a different ROM. If the device doesn't reboot by itself or do anything weird, then case closed. If it does do something weird, then I'm not sure what's going on.
Remember to have fastboot installed on your computer. Or else it won't work. You can easily install it by using this installer. If you don't know how to use fastboot through a command line, then use Flashtool or QuickIMG.

[Q] Atrix stuck on Moto bootscreen, unable to enter CWM recovery

I'm pretty new to the whole flashing business, so if whatever I asked does not make sense, please be patient. Thanks!
I recently flashed the Neutrino Rom V2.6 from V2.5p2. Got lazy and didn't do a full wipe before flashing (also my battery was at ~5% ) After the installation, I successfully booted into Android, but realized that the fresh ROM didn't have multilingual or sync support (since the Neutrino Rom is a stripped down CM7), so I booted back into recovery (still with low battery)
I subsequently flashed the addons provided by the dev for multilingual and sync support, and when I selected "Go back" in CWM recovery, it displayed a long string of error messages, I believe starting with E:\"........."
Ignoring the error messages, I selected "reboot system", hoping luck would be on my side, but it wasn't
the result of all this is is that I can only "turn on" the phone with it plugged, and it will go through loops at the Moto bootscreen...also if I try to enter recovery by pressing "power+vol down", the screen goes blank and does not enter CWM recovery. Further, I am also unable to charge the battery for some reason, because as soon as I plug the phone into the wall charger, it will go through the Moto bootloop
My question is, is this a hardbrick or softbrick?
If it's a softbrick, is there any way of fixing it, or has somebody else ran into a similar problem?
Please help me out here, like I said, I'm new to the whole world of flashing stuff, so much advice is needed, and any help would be appreciated!
Thanks a lot ahead of time

Before you begin, turn OFF phone, remove battery, and connect to wall charger charger. When ? appears, install your battery and let it charge for a long time. NEVER FLASH WITH LOW BATTERY!
You need to reflash your recovery. Before you start, perform a proper WIPE. SKIP THE FIRST 4 STEPS, read this:

When I plug in the phone without battery, it just goes to the Moto boot screen, and starts the loop again...the usual "?" symbol doesn't appear at all
I've done battery calibration before, where it was required to plug phone into wall charger without battery, and the "?" has always appeared

Try getting to that menu and let it charge for a while? Have you tried that? ANd I mean, let it charge for about an hour. Charging might take longer than usual because your screen will be on.

sorry for the late reply...and thanks for all the help
no actually am not, I still can't get the battery charged up, which is the biggest issue right now...
I think if I can find someway to charge the battery without plugging in the phone, it's possible to enter fastboot with a charged battery
otherwise, even if I get to the bootloader menu (fastboot, nvflash, recovery etc etc), when I plug the phone into the computer and select fastboot, it'll still say "battery too low to flash"
Just a suggestion...trying to help. What if you find out a fresh charged battery before starting the recover procedure? I dunno if it will work because I dunno if there is some kind of serial number checking at this low level in the phone....I see that under no circunstances could you charge your battery again...

Borrow or buy a battery. Or make a new thread asking how to charge battery. Title on the thread is misleading.

i use this method n it worked thanks..to bad my wifi still shows up error after i attempt to connect it it doesn't reboot thats good i think
low battery
Even i am stuck in recovery. No matter how many times i flash a ROM after wipe data/ cache partition and dalvik and then install the ROM i still boot into recovery when the ROM asks to reboot the device.
Here's what happened
1. Had a nandroid backup of older version of CWM mostly 5.0.2.x
2. Based on Nottachtrix thread installed the romracer recovery(updated flashable zip)
3. Updated to Nottachtrix 1.3.1 and successfully booted
4. Figured out that contacts everything weren't synced. So wanted to go back to older CM7 rom using restore ROM
5. Something went wrong during restoration. Data and other wern't restored and i guess only boot had been restored
6. Endless loop into recovery thereafter.
Trying out different things like flashing boot.img, recovery etc battery drained and couldn't flash.
Fasbtoot and other options triggered by using volume buttons and power button works fine. RDS also detects the device but bootloader unknown and other info all were unknown.
Since battery drained i was searching on methods to charge the battery. Had figured out that custom method for charging the phone needs to be implemented.
While playing around again with phone i powered it through directly through charger and opted for linux cold-booting which gave me the battery icon with the question mark on screen. Popped in the battery and it started to charge. So now i know i can charge the battery using this method.
I am yet to make progress on flashing ROM successfully again. Is my backup lost ? Did the error happen because i backed up using an older version of CWM or flashing to Nottachtrix changed something
I even restored successfully to my previous ROM after deleting .android secure from ext SDcard but still it threw me to CWM only :|
Help appreciated.

Xperia active died

Hello guys,
I have an Xperia active rooted with ICS (sony official) and it just died. I got a phone call and before I even answer it the phone crashed and was unresponsive. I removed the battery and from that point on it doesn't boot. I just get a vibration and then nothing. It needs to remove the batter again in order to shut down.
Some things that might help
1) No response or led light when plugged into PC or wall charger
2) Can get to Fastboot and Flashmode
3) I tried flashing again ICS and 2.3.4 but still nothing. The flash finishes OK but I the phone doesn't turn on.
4) When tried flashing with Wipe Data option enabled I always get the Abort Flashing error.
Any help will be appreciated. Thank you in advance.

Yes it's unlocked. I tried your suggestion by installing this kernel http://forum.xda-developers.com/showthread.php?t=1398910 and then the official ICS image but still the same thing. It vibrates when turned on and stays there .

Could it be battery related? You cannot enter clockworkmod, when you have flashed for example rage or x-kernel?

If it was batter then it shouldn't turn on at least when plugged into the charger? Also once I hit power button and vibrates then it stays there, it doesn't shutdown. If I press the button again it does nothing until I remove and put back the battery. I believe this is an indication that it's not battery. Also the first time when crashed when I was pressing the power button the bottom buttons (return home and menu) were turning on (not anymore though since it seems that doesn't boot at all)
I tried booting to clockworkmod but no luck . Just to make sure, how do I do it in Xperia Active? If I remember correctly I have to press the volume down button several times until it gets into to he recovery mode, right?
Yes, you are right. Try to relock your bootloader.

How can I relock the bootloader? What if the solution is to have an unlocked bootloader? Can I unlock it again since the phone is not responsive now?
Sorry for two many questions. I started really worrying about losing the phone now .
I just noticed that for rage kernel I have to wait for the blue light to turn on and then press volume down. I do this but still nothing. I started suspecting that might be a screen problem. Can someone give me the sequence to restart phone or turn off from the recovery mode? If this work and it means it's my screen I guess.
Maybe it has something to do with bootloader. I bet it can be relocked, you just have to search a tutorial. I would try it, you have nothing to lose now.

You can't turn off from cwm, just pull battery. Maybe screen is dead, so background screen. You could try logcat to see what happens.
So the blue light appear, but screen doesn't come up? So it's related to the screen I think.
If you flash sony stock rom for your device you should be able to relock bootloader, just search in the forum for solutions...

It didn't die while I was experimenting with flash. It was working properly for a long time and just died after a phone call. That's the guide I used to root it and install ICS in the first place. That's of no use now since at step 3 the phone doesn't boot anymore. Blank screen.

Get into recovery mode (press voluke down with phone switched off, then connect the USB cable), and then flash a stock FTF filr using flashtool
Sent from my ST17i using xda app-developers app
Hello dumraden,
I tried your suggestion but still nothing . When press volume down and connect USB cable the led lights green and I suppose I get into flash mode. Is this correct? I am asking because you mentioned recovery mode and I am not sure if it's the same thing.
Also the screen seems to be completely black! Like it doesn't light up at all, not even a light flick.
I also tried loading the rage kernel for 2.3.4 Android and then installing the stock 2.3.4 FTF but I get the following error:

Any ideas? If I untick Wipe data it flashes just fine.
I tried the new Flashtool and didn't gave me this error (with Wipe user data ticked) but still the phone is dead.
I noticed some new symptoms on my phone.
1) When is turned on it doesn't just freeze, it stays with a black screen doing nothing and after several minutes (not always the same time) it turns off again (I call this turn on-off cycle)
2) Today after several flashes I let it rest and after a few turn on-off cycles it actually worked. It worked for couple of minutes and I was even able to make a test call to it and worked but after few minutes it got back to the previous state.
3) I noticed that this turn on-off cycle consumes a lot of battery. After symptom (2) when the phone turned on I noticed that had about 25% battery. 5-6 turn on-off cycles after that the battery was completely drained (led flashes orange when I press the power button).
4) Now the phone can be charged from the wall charger
The phone now has rage kernel for 2.3.4 Android, the official 2.3.4 android of Sony. Also I tried to relock it using this thread http://forum.xda-developers.com/showthread.php?t=1563840 and unbrick it using this thread http://forum.xda-developers.com/showthread.php?t=1553601
I wasn't able to verify if the bootloader was indeed relocked. How can I do this with the phone off? flashtool says "Bootloader: ROOTED"

[Q] Xperia GO Battery

Hi! Can someone guide me into removing or getting access to the battery of this unit. I think the kernel is corrupted coz I think I flashed the wrong one. The battery drained out. So without a working kernel, I cant charge the phone. Even in USB to PC or directly to wall charger. I want to re-insert t the battery to see if that fixes the issue.
Can someone tell me if removing the battery then plugging in the usb without the battery if I can enter flash mode or flash boot to be able to flash the correct kernel or go back to stok room for the phone? Would that work?
Or I just need to reinsert the battery then try to enter flash mode?
SITUATION:
- cant enter flash mode or fast boot.
- can hard reset (Power + volume+)
- Cant turn on the phone
-just red led when plugged in then disapperas after a few minutes (not charging)
- the phone never got wet or never been dropped. (so im hoping this is a software issue)
- phone is rooted, unlocked BL with CWM.
-started when I flashed a flshable version of CWM touch version to upgrade from version 5 to 6.
Help please. Im thinking of opening the phone to access the battery.
The idea of removing non-removable battery is not the best one, unless you really know what are you doing - and i don't think you know it.
And i think this won't help you, really not.

You can hard reset - but battery is drained?
Once, i had problem like this one, but i managed to get into fastboot and re-flashed right kernel.
What were you exactly doing? Rooted and BL unlocked Go? What and how were you flashing (which rom and kernel were you flashing)?

sorry just a typo error, i mean i cant hard reset. I know how to access an embedded bat, tried it before with Xperia S. but I was hoping if can flash without doing that anymore?
Managed to disconnect and reconnect the battery; however I still cant turn it on, or even hard reset, or flash mode or fast boot. Crappppp! help. What can I do to bring this phone's life back. I flashed an update for CWM on recovery. Thats when this problem started.
any help out there?

Hi, i am having the same problem. I flashed the kernel for another model out of noobness. So removing the battery did not help at all?
OMG right as i was typing this, the rubber band trick worked and i accessed fastboot and flashed another kernel. It wont start for now, but maybe the battery needs to be charged for a while (red led). In case you dont know (if you still have this problem), i will explain what i did (the computer just detected the device, so i think im in the clear):
1) get a rubber band and put it around vol up button (this is for fastboot; for flash it would be vol down)
2) plug the phone to your computer
3) get the fastboot.exe file (google)
4) put the correct boot.img file (or kernel, i flashed the wron boot.img, so i did it this way. I dont know what the difference is) in the same folder as fastboot.exe
4) open command prompt, go to the fastboot folder (look up commands)
5) type in "fastboot flash boot boot.img"
6) the cmd will say "waiting for device..."
leave it like that; i got purple (i guess blue plus red) led after awhile and fastboot flashed the kernel.
I will keep you informed on success or failure.
EDIT
It worked, i have a running phone.
Hey! Thanks for the post and reply, would have done that. However, i sent my phone to a repair center, and they havent got bakc at me until now, its been 3 weeks.
Was your phone unable to go fastboot and flashmode too before? And when you charge it red led appears then goes away after a few minutes? My PC cant recognize the phone, the only indicator i had was the red led when plugged in which goes away after a couple of minutes.
How long did it take for the phone to enter fastboot? Coz, I've tried holding the button (Vol+) for almost 5 minutes and nothing happens.
Can you provide me the exact situation you had? and the clear cut steps you took to fix it? Especially how many minutes for it to go to fastboot with the rubber band on?
TIA!
@ madismet
your rubber band technique actually worked!! thanks a lot!
I was just about to give up on my xperia go, when I came across your post...
thanks!! :good:

Hi! Can someone guide me into removing or getting access to the battery of this unit. I think the kernel is corrupted coz I think I flashed the wrong one. The battery drained out. So without a working kernel, I cant charge the phone. Even in USB to PC or directly to wall charger. I want to re-insert t the battery to see if that fixes the issue.
Can someone tell me if removing the battery then plugging in the usb without the battery if I can enter flash mode or flash boot to be able to flash the correct kernel or go back to stok room for the phone? Would that work?
Or I just need to reinsert the battery then try to enter flash mode?
SITUATION:
- cant enter flash mode or fast boot.
- can hard reset (Power + volume+)
- Cant turn on the phone
-just red led when plugged in then disapperas after a few minutes (not charging)
- the phone never got wet or never been dropped. (so im hoping this is a software issue)
- phone is rooted, unlocked BL with CWM.
-started when I flashed a flshable version of CWM touch version to upgrade from version 5 to 6.
Help please. Im thinking of opening the phone to access the battery.

xperia p no charging lights, no usb detect,does not boot (not even the kernel screen

hello everybody,
i used to be active on the x10 forum.
but recently i switched to xperia P.
i unlocked the bootloader,
used fastboot to flash custom boot.img,
fastbooted custom kernel (FreeXperia),
installed cm10.zip with the CWM included in kernel,
everything works except wifi and bluetooth (which i guess is the rom's fault, so i dont really mind)
and then i installed apps from the cm10 file manager.
it detects my 16gb internal memory.
but my titanium backup and some other apps says it cannot access my internal memory, so it doesnt show any apps. (usb is disconnected)
so i thought mayybe some apps dont have access, so i thought i should mount my internal memory (although it already works for my cm10 file manager).
that was a very stupid decision because i used this code from this website which i got after i googled and used it on my terminal emulator.
guess what happened? my device got stuck/hang/frozen.
then when i pressed the power button, it was totally blank, no response and the screen went off.
i tried force shutdown by pressing and holding the volume-up & power button at the same time for a long time, that didnt work either, it had no effect, there was not even a vibration.
and when i charge it, there is no charging light.
it doesnt boot, it doesnt show me the kernel screen, or the CWM screen.
this is worse than a bootloop.
anyone who has previous experience with this?? or has a suggestion on how to repair?
any advice will be much appreciated :crying:

I think you've posted in the wrong forum - should be in Q/A.
Is your phone able to detect in flash mode? (while it is off, hold DOWN volume key and connect USB - check for LED illuminated)
Is your phone able to detect in fastboot mode? (while it is off, hold UP volume key and connect USB - check for LED illuminated PURPLE)

Hi.
1. Have you tried to charge it through the charger, instead of the usb por of PC?
2. If you tried, did you let it charge for at least 30 minutes? (Sometimes the battery drains so much that the phone needs time even to show it´s charging.)
If the battery charges, you should try flashing a Stock Rom through Flashtools.
If it doesn´t, then I can´t say you should do it but if I were in ur position, I would surely open my phone and try to charge this battery somehow. Google a lot to learn how it works, the wires, what is positive and negative and bla bla bla because your biggest problem NOW is not having power to work with the phone.
Hope you have good luck!
=)
Sorry please post your thread at Q&A

i have reason to believe it maybe related to the battery. maybe the battery is still running. how do i physically shut it down? the holding power button and volkume-up button trick doesnt work.

Use this guide to open the phone up and just disconnect the battery for a few minutes. Then try connecting in either fastboot/flash mode. The phone may need to be repartitioned and reflashed.
Same issue
Hi Davin-J
Did you finally solved this problem? I have the same now. And my battery should be good.
...............................
1/2 day later:
It was the battery. I managed to get it back to life as copper62472 told us. The strange thing was, that the Sony charger didn't charge the phone battery; may be because I bricked the phone before with system/data/cache wiped and formatted. I was not even able to restore it with SUS, because the phone was not detected at the USB.
Then I charged the battery outside the phone with a current limited power supply. After putting the charged battery back into the phone, restoring with SUS worked without a hitch.
Help

My xperia p is also in dead condition now. I'm thinking like it's battery is fully drained. It all started with flashing of a custom kernel.
i could take the battery out. i need to charge it by external means. How can i do that? Please help me.

S2 Not Booting

So yesterday morning I went to turn on my phone, but nothing happened. It was on the charger all night so it should have been a full battery.
Here are my symptoms:
1) AC plugged in without battery - Phone's screen turns on for a second, turns off, and then repeats.
2) AC plugged in with battery - Phone will start to charge (has the loading symbol in the battery), but then turns off immediately. It cannot boot into recovery. It CAN boot into download mode, but my computer will not recognize it to restore the phone with odin.
Any ideas?
I don't have an official upgrade until October, but I'm going to call customer service to try and get them to bump the date up so I can get a new phone.
First possibility to suspect is a failed battery. If you know someone else with an s2, ask to borrow their battery temporarily to see if your phone will boot. Or perhaps go to an AT&T store to see if you can borrow a battery.
If it's not the battery, then the next step to try is to boot into download mode with the battery out of the phone to see if Odin will recognize the phone with the battery out. With the battery out of the phone and the USB cable plugged into the computer, hold down the vol down button while plugging the USB cable into the phone. The computer will supply the power. This assumes that you have the proper "Samsung USB driver for mobile phones" installed on your PC.
That's a start.
I am having the same issue with my s2. i had shostock installed on it a few weeks back and it was working fine. then it just stopped working. i tried rebooting but it keeps on going on bootloops. I tried using odin to flash back to stock but no go, just bootloops. kies just dont work for me. i know it isnt the battery cuz i have the charging cradle to charge the battery and the phone goes to odin mode without the battery. Any help is appreciated.

It sounds like you got a successful flash of stock. Boot into recovery and perform a wipe data/factory reset.

OK. Did the flash to stock succeed? In other words, you got a pass in odin?
Which version of SHOstock was installed, the latest? And which version of stock did you flash?
i flashed SHOstock v3 before all of this happened. i flashed ucle5 stock rooted. battery icon flashes capacitive keys blink over and over again. if i unplug it nothing happens. i may have to try UCKH7 once im done downloading it.
** after flashing KH7, i go to recovery to wipe/factory reset... there is a message saying
Installing Multi-CSC...
"can't access to '/system/csc/ATT/system/'

This is sounding a bit like nand read/write corruption, which is fixable. Try this:
1)Go to this post and download the Tar version of Siyah 2.6.14 Kernel. Flash it in PDA without ticking Re-Partitioning.
2) Successful? Nice. Next, flash the full stock Gingerbread distribution from the Download Repository, I777UCKH7 including the bootloaders and everything, in the PDA slot.
3) If that is successful and boots normally you are done. If it is not, then:
4) Download the SBL Bootloader from the Download Repository. Flash it as PDA in ODIN, without ticking Re-Partitioning.
5) Flash the Kernel, as in step 1.
6) Flash the full stock Gingerbread distribution, as in step 2.
Will try that later. Thanks for your help!

Going through the exact same issue with my kids phone with the same results. Tried creepy's 6 steps, but still no luck.
I think it was caused by my kid killing the battery.
update: got it to boot into custom recovery, then reflashed ROM. It stills acts weird though. Very laggy.

When I plug then phone in (automatically turns on when plugged in, power button is broken), the battery logo and hardware buttons flash erratically for up to a minute then nothing at all. I've tried different batteries and different cords. The only thing that seems to bring it back to life is letting the phone and battery sit unplugged for 2 weeks up to a month and trying again, but it's very hit or miss. This only seems to happen when the battery completely drains.

What phone do you have... the AT&T SGH-I777 does not have hardware buttons, but maybe you mean the capacitive buttons which are part of the display? Your previous post was sent from an Infuse? If it's not an I777 then you need a different forum.
If the phone that has the problem is an SGH-I777, then... what firmware is/was it running? Is it rooted? Is USB debugging turned on? Have you been able to boot into download mode since your first post? How long was the power button broken before this problem first manifested?
I think you need to get into download mode and flash stock firmware.
You also may need to see if you can do something about the broken power button, since that may be involved in the problem. That would mean either taking the phone apart and trying to mechanically clean the button or move/press/activate it a lot to get the dirt out so that the problem clears itself, or it may mean getting it replaced.

It is the I777, capacitive buttons is what I meant.. I apologize, I'm still fairly new with terminology.. Yes, I have an Infuse also, it's my backup phone because I can't get the s2 to charge. It is rooted and flashed, running 4.2.2 (Avatar ROM)
The problem is, it isn't holding enough of a charge to do anything. Aside from the previously stated issue, it will go into download mode, but the screen will only stay on for maybe 5 seconds max. The power button has been broken about 6 months before this issue arose. This only started happening about a month ago when I let the battery discharge completely. To test my theory that it's a battery/charging issue, I got a backup battery (which allowed the phone to work again) and I allowed that one to discharge completely. Now I'm having the same issue with both batteries. I was able to get the phone to power on once after letting the phone and battery sit disconnected for about 2 weeks.

Firmware is CM 10.1, it is rooted, running AvatarROM. USB debugging and mock locations were turned on. It had no issue charging while it was working, it was after I allowed the batteries to die that I started having issues. Even on the second battery, it would continue operating as long as I kept it charged.

I have never used Cyanogen Mod or any of the other AOSP firmware, and I don't know how the firmware would affect this issue, if at all. But I suspect there may be some link.
I think what you need to do is to flash back to stock firmware, or perhaps use one of the stock plus root packages, and then a custom kernel, and then reload CM 10.1. So try this:
Pull the battery and leave it out. Open Odin3 on the desktop and then while holding down the volume buttons, plug in the usb cable. See if the phone will boot into download mode this way, and if Odin will recognize it. If so, then go ahead and flash the stock of your choosing. I think if it were me, I would flash 4.0.4 UCLL6 plus root.
