Hi, this is my first post. I have tried to search and look through the question threads, but nothing seems to be close to the problem I have here, hoping someone can help me.
I have this Xperia TX, recently given by my friend, it can boot up ->sony->ribbon-> entering system->shutting down, it's not like a sudden blackout but more like a command sent telling the phone to shut down, it has the window saying shutting down and vibration at the end, but the shutting down is instant, can't operate yet. I made several approaches trying to fix it, these are what I have been done with it.
-Flashing different stock ROMs using flashtool, the flashing went perfectly without errors, and phone will boot and install new system until the setup wizard (languages, time etc) comes out on screen, and it shuts down right away.
-I used flashtool to unlock BL, succeeded.
-I flashed TWRP, it can boot into TWRP without any problems and working fine.
-I formatted the phone partitions using TWRP, working fine.
-I flashed cm-12.1-20151010, and same thing happened as soon as the system launcher comes out.
-And I flashed stock ROM again, the problem remains.
The phone won't charge the battery, so I tried using a separate charger avoiding 0 battery situation (I do see the battery icon showing 50%+ when it shutting down), and I also tried another lt18i battery (don't want to buy a new one yet in case the phone is dying), and there is no different.
I don't understand the problem, all the operations work fine but can't boot in system, doesn't seem like a hardware thing but what else can it be? I am not hoping to fix it any more at this point, but can anyone tell me what could possibly cause this? Can I read a boot up log somewhere so that I know what happens during booting?
I hope I didn't break any routine or do anything wrong here, if I did, apologies in advance, thank you.

Hi everyone,
I have a problematic Nexus One. I've googled the issue and read all the corresponding threads and none of them seem to have boot loop issues as bad as mine. At least I dont think so, anyway.
Where should I start? I recently bought the phone off ebay. The seller did clearly state the phone's issues and that he couldn't be bothered fixing it, let alone paying over $200 to send it back to Google to be repaired or replaced (from Australia). Call me a sucker for punishment, but I do like dabbling in electronics so I thought I'd give this a go and hopefully will be successful. It wouldn't bother me if it rebooted once every few days then rebooted again normally but this isn't the case. I'll try to describe it's behaviour as precisely as I an and I sincerely hope the collective expertise on this forum will be able to help me successfully resolve this issue. BTW, I've been using a gorgeous Desire since July.
The Nexus one is running Modaco r21, 4.06.00.12_7 radio, 2.6.32.9 kernel, CMR 2.5.1.0.
1. When the phone has been powered down for at least 5 mins, it will power up as normal. If left alone on the bench or very lightly used ie a few minutes, then pwr button sleep, no problem. If I continue 'sleeping' the phone every few minutes while using it it continues to function normally for a few hours. If I don't 'sleep' the phone and use it continuously, then after about 20 mins it goes into a reboot cycle with the static 'X' going on and off every few seconds then ending up with the continuously on "X" with the unlocked padlock underneath, which is unrecoverable until the battery is pulled.
2. Battery reinserted immediately after removal and the reboot cycle continues. I can boot into the white Recovery or Fastboot sreens but when I select an action like Recovery, the boot loops starts again. Battery pulled and reinserted again, boot loop occurs again. Pull battery and leave it out or powered down with battery inserted for 5 mins, reboots normally. Then point '1' above continues.
3. I have Rom Manager, Titanium and Superuser Permissions installed. I received the phone with Eclair installed and after many attempts managed to install the new radio and Modaco R21. Last night I tried doing a back up via Rom Manager since I cant get into the black Recovery screen and now Titanium and SU are force closing.
This is all I can think of right now and will update with more info as they come to light. I've been trying to install setcpu to see if underclocking will help however I have been unsuccessful due to SU force closing. I am an Android and Linux noob but am always willing to learn. I really would like to get more stability in this phone so I can either use it as my primary or back up.
Thanks in advance for all your help.
Edit. I magaed to do a factory reset when it dont momentarily allow me into Recovery mode. Wiped all data and davlic as well.
My first instinct is that the phone has suffered or is suffering from a heat problem of some type.
Do you have the android SDK set up on your computer? You should be able to flash an aftermarket recovery using the "fastboot flash" commands. You could also use the "adb reboot recovery" command to reboot the phone directly into recovery mode.
I'll give your suggestions a try. What fastboot commands should I be entering? I am an absolute virgin with all this.

Hi again,
I've installed Android SDK and usb drivers. Where do I go from there? I am a complete newbie at this so please be kind.
julian.kueh i was posting to ask how things have been progressing along this matter?
I got the same problem. No matter what I do, I can get into Recovery. It stay in loop with X
I change twice recover and nothing.
Hi all,
seems like my OB is broken. But just in case this is still a repairable issue and since I would of course love to keep my good ol' OB, I'm posting my issue. Maybe there is still hope
It all started after OTA-Update from CM10 nightly to the stable release. I noticed that from time to time the power button did not work after charging the device over night. So for example, the device woultn't wake up when pressing the power button, but reconnecting to the charger did the trick. But then again, I often coudn't turn it back to sleep with the button.
Every time that issue appeared, the OB acted normally after removing the battery for a moment.
But not today.
Again, I couldn't get it to lock when it was active because the power button did not work. So I decided to wait until the screen turned off after the timeout which it actually did. But then again, I couldn't wake it up.
So, starting with the "normal" procedure, I removed the battery for a moment and tried to turn it back on, thinking that it'll be just fine again. But not this time. It didn't react at all. Even after connecting it to the charger - the display turned on and showed the charging animation, but I couldn't get the device to boot.
Next step: Common unbrick procedure. Since it was the only thing I could still do with the OB, I reflashed the good old patched v20n using SmartFlash. I used the exact same program and bin files that I used long ago when I initially rooted the device. So that should have worked like a charm. It didn't.
First try: Flashed with SmartFlash and restored an old nandroid with Zeus ROM on it. Rebooted and... oh great it's stuck already on the LG logo.
Okay, 2nd try: Flashed again but this time just selected the reboot option in CWM. Device boots, plays the animated LG bootlogo and reboots into bootlooop....
So far about my poor OB
Now does anybody have any idea what could have gone wrong with the device?
Of course it could just be a coincidence that these issues started right after the update and the cause may be an ancual failure of the HW button.
But really, how likely is that keeping in mind that my OB worked like a charm all the time before the update?
Any ideas, comments or even suggestions what else I could try?
Smartflash must unbrick the device if the problem is not a hardware problem, if you have tried it and it didn´t work, i am pretty sure that you have to take the phone to warranty.
Anyway, you can try to flash a patched bin/fls with root and recovery, after flash phone will go to recovery, then do a full wipe (Data, cache and dalvik) and reboot.
Reflashed with SmartFlash (to get into CWM), wiped all, booted v20n; no power button, all other HW-Buttons work :/
Hardware problem.
That's what I thought as well, but:
Just managed to restore my Zeus ROM Nandroid image, cleared cache and it booted without problems. Aaand: Power button is working again! Locking/unlocking as well as turning on/off the device entirely works normal!
Now seriously, this issue keeps buggin me - how can something like that happen at all??
I mean, if I would mess with the key mapping and remove the mappings of the power button, it might not work anymore for locking and unlocking the phone. But what could possibly cause that button to not even work for powering on the device? I always thought that must be a hard-wired functionality??
Droid 4 running Stock Jb 4.1.2, Safestrap 3.11, Liquid smooth 2.9, CM (last stable)
Everything working fine for a number of months, installed Liquid smooth via -> delete romslot 3, create romslot 3, install Liquid 2.8.
It ran for a number of days no problems. Restarted fine, all features worked great, even the annoying random restart from 2.4 went away.
6 - 10 days in, im surfin' the news sites at work, put it down, screen goes black, i pick it up. Hit the power button cause i realize its off and it just boot loops... so bad i had to vol-/+ pwr, go to flash mode and THEN turn it off b/c it just kept trying to restart, hang on logo.
I got home and decided to AP flash the latest:
9.8.2O-72_VZW-18-2
Blur_Version.98.72.182.XT894.Verizon.en.US for the maserati.
Boot looped a few times, i was able to get it to go into recovery mode, after that it loaded up the stock JB system. First boot it crashed and restarted, second boot it loaded but only the keyboard worked, not the touch screen. Went to the in OS option of factory reset mode + delete storage.
Rebooted, worked. Checked it a few boots, everything is fine. I use Druid 4 Utility Xt894 JB version and apply the root. Works great. Install safestrap, Create new partition, install liquid smooth 2.9. Works for an afternoon... at work today the touch screen stops responding, i restart it a few times. I try to enter recovery mode. Now im in boot loop again...
I've tried re flashing it again, a few times. I tried even going down to the previous release of JB for the phone. STILL 4.1.2!!!! But nothing.... it just boot loops... what did i do wrong? It was running great. No tweaks or anything done to it prior to it having its melt down.
Help please.. ive provided as much information as possible and though i only joined XDA now to post for help, i have read it for a long time as my main source for my phone and have donated to both CM and Liquidsmooth teams previously..
help!!!
I can't see where you are doing anything wrong. You have obviously done your research and have a good idea of what you are doing. I see, after you fastbooted, you went back to Liquid. I think I would try running CM10.1 or even stock for a few days and see if you have the issue there as well. If you do than it sounds to me like it might be a hardware issue. If not, maybe try re-downloading Liquid. Perhaps your zip got corrupted somehow.
I would love too. In fact i would be willing to run it on the stock crappy 4.1.2 if i could get it out of boot loop this time...
It just keeps boot looping on the logo. AP Fashboot flash and BP flash work but recovery and normal boot/reboot mode just goes into M logo boot loop.
I've re downloaded the 4.1.2 jb SBFs from 2 different sources to ensure its not a corrupt file, tried 18_1 and 18_2 software versions...
Is there a way to use the abd shell to get into the filesystem and check whats going on? Is the SBF the last call? or is there another route to see whats going on or just flash EVERYTHING? Like completely back to stock?
I can find my way around a PC file system but im not familiar with linux. Please help me understand, Is it like having CMOS and BIOS settings or equivalent to damaged CMOS firmware? What am i not replacing/reverting by SBF and HOW can i replace/revert BEYOND the basic sbf...
If ya point me in a direction or to someone who can help me out i can do all the foot work just point me in the right direction?
Is this applicable? I found a site talking about using CWM in a ADB shell file push to possibly get access to more features?
The article also goes into reading the busybox / ADB command screen? (sorry for not proper jargin) and see what its doing during the boot loop before it restarts?
Id add the link but i need more posts....
Update: Flashed 18_2 again with a "factory cable" i made, let it boot loop a series of times before it started up into the stock system again.
At first, again the touch screen wouldn't work, random lockups and restarts, etc. Since i just got it into the main system again and i had to leave for the weekend for a trip(no wifi or network), i couldn't mess with it all weekend but i left it on the whole time and kept checking its functionality... gradually its come back to full function. Touch screen works and is accurate, no more lockups, no more restarting, even stopped boot looping when i restart and enter recovery..
Im not sure and i couldn't find any forum converstations or write ups to support to idea but i think after a major crash and you flash new or reflash your SBF, it seems the phone needs time to recalibrate and index? Not sure, but just an FYI. Gonna try loading SS and liquid again.
I've been using Hazou's ROM for months, worked fine, haven't changed anything. Today I was browsing in Firfox with quite a lot of tabs open. I kept getting odd warnings of apps having low memory. I could do nothing with these popping up every second so I restarted my phone. It was taking forever shutting down so I did power + volume down.
Now it's stuck at the very first screen, the 'warning bootloader unlocked' screen. It just stays like this and occasionally resets and makes the reset buzz and that's it. I can get into fastboot by holding volume down and power and releasing but whenever I try and select an option in fastboot it just resets to the first screen or fastboot again.
I'm mystified because usually people have issues performing the rooting etc but it was a while ago that I successfully rooted the phone and unlocked the bootloader and put on a rom and had been using it. Could my hardware (memory?) have broken rather than software?
Any help would be great, thanks.
Ps. fastboot says:
"Fastboot Reason:
max download size: 100mb."
Possible it's always said that and it means nothing.
Ps. Possibly this thread is of use to me? I'm not sure if it's the same problem. http://forum.xda-developers.com/showthread.php?t=1945176

What does it say when u try to flash a recovery? a stock system image? wipe data? wipe cache?
If any of those mention an i/o error the phone is beyond repair from the knowledge here or someone can come up with any kind of solution. More phones have this error and it can happen to anyone, it is just rare.
Hi everyone, I'm having a lot of problems with my phone: last night, after it dropped to 0% battery life, it wouldn't charge. So i waited a while and ifinally managed to turn it on, but It wouldn't go past the Cyanogenmod logo. So i tried few things,first wiping cache, then factory reset from TWRP and I even tried the "Factory" option in the fastboot screen. Nothing worked, and it even got worse I think, TWRP says it's unable to mount /data partition and /storage partition. I don't know what caused it, and i don't remember the precise moment it became "unmountable" for the first time (since I've been trying to fix this thing for like 24 hours now).
Since i couldn't fix it via recovery, I tried looking for people who had the same problem on the internet, and I tried everything i could find. (like this: http://forum.xda-developers.com/showthread.php?t=2683787).
I then tried to go back to stock rom via adb and fastboot, but without success.
The main problem with fastboot is the fact that it doesn't change anything in my phone, it gives no errors when i try to flash the stock rom, but when i reboot my phone, nothing changes, or at least this is my opinion, since I still get the cyanogenmod logo, and TWRP doesn't get replaced (while it should go away, since when in the whole process of flashing the rom, i also flash recovery.img, which shouldn't be TWRP).
I tried a whole lot of other commands too, like "fastboot erase recovery", but TWRP is still there, and so is the cyanogenmod logo.
This is why i think fastboot is unable to write in my phone, but if that's the case, it should at least give errors.
So, wrapping up, my data partition seems to be corrupted, and flashing the stock rom still gets my into a bootloop (with the logo from the previous rom and TWRP still there).
Do you have any advice?
P.S: my phone is a xt1068
Are you able to pull logcat?
Logcat command works, i don't get errors in the terminal, but in the text file there's only this line : "/sbin/sh: exec: line 1: logcat: not found"
Dmesg works though, I don't know if it's helpful

I have same phone, you mentioned you also tried to flash stock rom without success, did you flash the partition file aswell before flashing system and the rest of files ? Check the flashfile.xml file into the stock firmware folder to make sure you not missing anything.
Code:
fastboot flash partition gpt.bin
Good luck.
i'm on the same boat. It seems it's a NAND issue, but how come it happens randomly?
It seems to happen (its a bit rare, so don't get worried) when you let your battery drop to 0% and the phone suddently turn off, like what happened to the OP.

If it's a bit rare, how come there are a rather interesting quantity of posts regarding that matter? I'd like to know WHY I can't write even with fastboot. There should be a way of unlocking the NAND / partitions. Even if I try to hard brick it, it's impossible.
PS: can we someone a look at this? http://forum.xda-developers.com/showpost.php?p=56608822&postcount=2
Possibly if we can force the way to QHSUSB mode, phone can be saved.

Unfortunately I didn't quite understand what that is about, if you happen to try it out let us know.
Anyway, if we don't manage to fix it, I guess I'm going to try and take it back to the store, since it is a common problem. Only problem is I'm on a custom rom and I can't even go back to stock and relock the bootloader, so I don't think they are going to replace it, but it's worth a try.
You can try by helping me to look for a circuit PDF from the board or trying it yourself.
I could try and disassemble it, but you're gonna have to wait a few days, I'm not at home and I'm gonna be back on the weekend.
As for the circuit pdf, I was only able to find videos and guides on how to disassemble it, unfortunately
Dude, no worries. Ive took the back out with all the screws, but I have nothng to make shorts with.... I'll come up with something. Take your time and keep me posted.
any news concerning this problem? i have tried searching for a manual but I did not succeed.
Anyways after finding the manual, we can short circuit the 2 capacitors there and the phone will be in qhsusb mode.
And after that ?

After that.... well.... after some research, we'll be needing singleimage.bin to use the blankflash utility for lollipop phones (mbm-ci 5.0 lollipop) so somebody can generate the singleimage.bin for us.
Once we have that, we can try to flash the phone at lowlevel to see what happens.
I will search the internets in hoping to find the schematics of this phone.
Keep me informed if you find it faster .
Cheers mate
we can connect through hangouts / etc.
