Boot loop and not detected on pc - Xperia Z Q&A, Help & Troubleshooting

So it's been a while since i used my xperia z, it started developing charging issues and i resulted to charging the battery externally, of course this was a tedious process. I decided to just do a simple hack one time and started using one of my DIY 3.7 lithium packs around (4000mah) as the phone's battery, it was working and i got to use the phone for quite a while though it was a bit uncomfortable, anyway i have no idea what happened later. I has stored the phone for a few months and never really used it. Last time i tried booting the phone went straight to the 'optimizing apps' loading screen and it was taking quite long (i was not patient) so I just disconnected and stored it again. Currently when i try to boot the phone just boots to the sony logo screen and goes off after 2seconds, also it cannot be detected via pc( note, yes i had the charging issue but once in a while it was detectable via pc (i even tried unlocking the bootloader one time but failed). Anyway someone kindly let me know how I can fix this, if all fails my plan is to just buy a second hand motherboard from china and fix it.

Does PC detect your Z in Fastboot mode?

[Q] Possible brick during rooting?

Hey all, thanks for taking your time to read and possibly help me out with my problem. Yesterday I've tried rooting my droid in order to put cyanogen mod on it later. The reason I was interested in doing that was because I felt as droid was not working to it full potential and constantly crashing apps on me (browser, games, weather, etc). A friend of mine suggested cyanogen as he himself owns it. Being that I've did plenty of CFW on PS2, psp, xbox and mp3s/ipods, I thought there shouldn't be a hassle with this.
I followed the procedures listed on cyanogen's wiki page in order to complete the rooting process. But on the step where it asked to instal .sbf file trough RSD lite and wait till it says "pass" I've ran into trouble.
During the unpacking of that file to the phone using RSD lite the phone was undergoing several reboots, and after finally finishing the reboots on my PC screen in the RSD Lite window it showed 100% complete "please reboot the phone manually". I had no idea how to do that manually as the phone just kept going on and off by itself. (also for some reason it kept saying "error" force close/wait/send notice. But I thought it was probably just the process. After trying to reboot the phone a couple of times nothing worked. I didn't receive any "pass" signs on the droid screen.
I've got a little worried about the whole process and decided to shut the phone off and during that close the RSD Lite on my computer. Doing that made no further improvements for me. The phone just kept going on and off like crazy while in USB and not turning on at all while not plugged into either USB or AC. I've decided to go to recovery mode and just reset everything to stock as I was running out of time and had to get some sleep before work next day. After reseting the cache/data files I rebooted the phone but the same things kept happening to it. Now it was asking me to reconnect with gmail account and all that intro stuff. But the phone would always end up locking up and shutting off somewhere in the process of reconnecting the account.
Fast forward to today I've read that its possible to complete reset everything to stock version trough .sbf file once again. But now the problem consists of the phone not having enough batter life. (I'm not sure what the screen is called where the process of dumping .sbf trough RSD lite starts) but that screen keeps saying battery is too low to do anything with it. And mind me it has been charge for a very long time now in the AC adapter.
Now it also appears as the problem has worsened. The phone does not start up at all in either USB or without connection. It only starts up in AC adapter but then it shuts off in 2 minutes and back on and off , on and off. Recovery mode can't be accessed in any way, at least any way known to me. The black .sbf screen can only be accessed while the phone is not connected to anything but still keeps saying the battery is too low. And I've noticed the phone getting extremely hot during AC charge. (another small detail that sometimes when the phone does turn on and goes to home screen opening up the landscape view does not increase the length of the top (pull down) bar in horizontal view.
I've tried taking out both battery and sdcard and putting them back but no luck. I'm really lost as to what I can do next in order to fix this problem.
If you need any further information please let me know and thank you again for trying to help me!
I don't really see how you managed to get a fc with rsdlite.
Did you reboot your phone (turn off) then boot into usb recovery (power on while holding up, for the droid)?

I am by no means an expert and could be just wasting your time but in the absence of expert opinions something is better than nothing right? It sounds to me like maybe you have a bad battery that as luck would have it failed during the update/rewrite. Have you tried getting into recovery with the battery pulled running straight off the ac adapter? Hopefully you made a clockwork/nandroid backup before you started?

I'm not an expert either, but having just successfully rooted my droid and installed cyanogen I feel the need to ask: did you hold up on the d-pad while RSD rebooted the phone the first time? If not then you needed to immediately restart the process.
I think you need to use a separate battery charger (meaning that charging battery without a phone) to charge the battery.
Sometimes, battery won't hold a charge when your phone is a brick.
BTW, it appears that you are having the same issue with mine.
(I can't post a URL because I am new here, but you can take a look at my article in this section, called "[S.O.S] A rare MILESTONE brick situation". )
I had the same problem (battery won't charge and phone won't start-up), I had to purchase a separate battery charger, and then flashed another SBF, to make the phone charging normal. (Although my phone is still a brick, but not a problem with battery. )

[q] reboot problem

Hi guys, so I've had Xperia X8 since june or so. It always worked perfectly, got rid of stock eclair really early and used GingerDX for a long time daily on stock kernel 'cause it's newer edition of phone I'm told I shouldn't do anything about it, just install rom on stock kernel. And that was fine really but yesterday my phone started rebooting randomly and I could tolerate that, but then it started rebooting over and over in circle without ever making it to run the system. Today, however, It just got stuck on Sony Ericsson words logo and it was like that whole day. I thought first maybe battery is dead or something but obviously it's not. So I repaired it through Sony Ericsson PC Companion and, naturally, it returned to eclair. However it kept doing reboot stuff, only now it starts the system but as soon you disconnect charger phone reboots and start system again and after about 5 second reboots again and so on. When I plug charger in, it shows it's charging and it's fine it works but sometimes when I try to type something or just randomly do something it reboots but it's not that often. Once phone is 100 charged I disconnect it and after some time it reboots and run again and show battery is 19% or so and then reboots again and again and so on in circle but battery never dies. So I tried factory reset, installed GingerDX again and it still does this boot thing and just won't survive without a charger. Also when I repaired it through PCC eclair wouldn't let me connect to market aka google play it said: "can't establish a reliable data connection to the server" and I tried factory reset and it didn't work. Facebook, browser anything else internet related did. Could anyone take a guess what seems to be a problem and help me fix it? Thanks in advance
next time write a post clearly
Maybe theres a problem with your battery.
Consider replacing it.

Absolutely a battery issue!
Try calibrating from recovery or terminal emulator.
If not helped, u should replace battery!

Hello! Have you solved this problem? because I´m inthe exactly same situation than you are and I can't be sure if is battery issue, Did you check battery?

.199 keeps killing my micro USB port!

Twice now since updating to official .199 UK unbranded i've been hit by a bug where my phone won't recognise charger unless its turned off. It's fine for a couple of days then gets very random about whether it will charge when turned on. Usually this followed by the next day it won't charge at all. This time i've noticed my laptop won't recognise Xperia T internal storage either and ADB/USB debugging don't work either.
I've hard rebooted, booted in safe mode and factory reset from within the phone and it makes no difference. Sony no doubt would tell me charger or port is broken and use returns process but when turned off phone will always charge... It also has no problems with the laptop flashing it or fastboot mode from turned off so this is no hardware fault with my lead, ports or charger. I've reflashed kernel on its own with flashtool, also fully without wiping and fully with wiping NO DIFFERENCE.
So the only thing that will fix this is SUS repair function, every couple of days? Very stupid bug worse than the 100% charge with .295. You can no longer rely on the Xperia as a main phone in my opinion unless your prepared to carry a laptop and internet connection with you everywhere. What a disappointment.
Further to this I have just repaired and even that hasn't done anything. Just used flashtool to revert back to ICS software and my charger is immediately recognised on first boot. I will now update using SUS again to .199 and I bet it will still work for a couple of days and then start to trip out again. Where the hell can this bug be lingering though if it can avoid factory resets and full SUS software repair?? What can downgrading reset that nothing else can... Very confused and disgruntled now. I suspect you could also revert to 4.1 with same effect but I just had ICS firmware handy so used that. I will test 4.1 next time
ICS only works. It gave me a update to 9.1.A.1.141 over the air so I did it and it broke my port again. I flashed 9.1.A.1.141 manually and its still broke - that was the software I was using before 4.3 and it worked fine. Is it seriously possible that these 4.3 updates have done something so bad to my phone that only the software it originally came with will work properly because thats how it appears to me now. I can't charge while turned on or have my laptop recognise the Xperia T internal storage unless using 7.0.A.1.303. Phone about to get thrown against a wall I think.
Maybe your battery power control is ruined.
Have a look here: http://forum.xda-developers.com/showthread.php?t=2688272
Thanks for suggestion but i'm not so sure. I mean it charges fine turned off, it charges fine on 7.1.A.303. And another symptom is not being able to connect my PC to phone. Surely if it was just battery/power control it wouldn't charge from PC but would still connect and allow me to transfer files. I also don't have any of the random reboots the OP had. I'm so worried to send this in for repair. Last time they did a software update and sent it back with original problem. Then they fixed 2nd attempt but caused some cosmetic damage and it didn't last long. Then my operator replaced it as I said I lost trust in the repair centre. I only got this one Nov last year and already it's having problems... I'm either unluckyist T owner going or they have some serious issues.

Very unlucky... my T is one year old, I installed every kind of rom/upgrade/downgrade and still works flawlessly.
Could they have replaced your old phone with a regenerated unit?
Your USB port is ok, that's for sure.
Like any other electronic component, a fried power control could behave in many different ways.
Yours could have problem when it has to work with a firmware that manage the power in a certain way.
Even when you connect to your PC, the power control of the battery is called to manage the power coming from the computer: in fact the phone usually charges during any operation with the PC.
And this explains why the phone charges fine when turned off.
Now the question is: which is the power control ruined? The one of the battery or are there other power controls?
Let's make it clear: this is just my hypothesis
If you don't trust in reparing service, why don't you try to repair by yourself?
You need a screwdriver (for only one screw) and a guitar plectrum to open up the back cover.
That's all, it's very easy... on internet there are some video guides... but remember that this way you loose your warranty!

[Q] [PLEASE HELP] HTC One M7 not charging when on.

Device: HTC One (M7) Stock ROM
A few days ago, my never rooted, stock firmware, no unlocked boot loader, no custom ROM, never dropped HTC One (M7)'s battery died. Plugging in the charger had no effect, absolutely NOTHING. Tried 6 different cables and 9 different locations to charge it, nothing. Waited a while, dying in desperation. Then after so much of panic, I plugged it again, and randomly it started charging. But the charging had a loop - showed a bright orange LED with the power symbol on a battery for about 5 seconds, then a dim orange LED with the green battery charging, and a number, for about 10 seconds. The loop kept repeating. Eventually I could turn it on till the (incredibly low capacity) battery could live. So I did about 10 resets to it, and the situation would not improve.
Since my phone just decided to do this to me just before a long journey of mine, I was quite upset, and eventually infuriated to the limits. I decided to take it along and try different things to it - tried, tried, cleaned the ports, searched the net, nothing.
One fine day it decided to break the loop - now it charged, but only when off.
And today again its started the loop.
And here I am, begging for some help. I'm starting to hate this device now. Please help me.. :crying:
P.S. : I played a lot of Clash of Clans on the phone - it heated up a lot. Hope the info helps (Possible corrupted overheating charge instructions of the phone,etc.)
please help i love this phone cant lose this at all

I am having the same exact problem right now. its very annoying. I have to drain the whole battery to charge it again. and its in that loop that you mentioned. plus it does not charge when you put it on charge when its on. it doesnt even have that charging light. it only charges itself if its off and if there is no battery left, i have to put it on charge by draining the whole battery by using apps and stuff and i am so pissed right now i cant find a solution to this. Did you find a solution on how to get this fixed?
I am currently having a similar problem where I can only charge my phone if off. Hopefully someone can help!

I have found a solution to this. I am really happy since i am able to use my phone again.
Let me state what exactly i was going through.
I had to use the phone till it actually turned off completely consuming the whole battery and it was very frustrating because i had to deliberately use the phone till the phone shuts down and charge it. And once it started charging, it has a weird stupid way of charging. It shows that its charging and it goes off, comes back on and shows its charging, then it goes off... When it goes off the red light goes away...then comes back on.
I've read other threads and forums about people having the same issue. Others say they're not even able to connect their phones to the computer. You all should try connecting your phone to a computer and check if its able to transfer data.
If that happens, then you're saved. Because this really worked out for me.
Now, i'm not really sure what kind of bug this is, but here's how you fix this.
If you're able to transfer data to your phone, you must browse your phone on the computer and copy a file (or a couple of files - in my case i transferred a movie folder that had a couple files in it)
And guess what..i put it on charge and started charging like normal oh my god i was happy as hell
Thanks. I hope the same works for you all, people have been saying you have to clean the charging port but not really

I tried with and withouth usb debug mode. :crying::crying::crying::crying:
Is this a sotware problem i guess? it wouldnt charge at all if it was hardware right?
Just checked and my phone now says "the usb host cable is plugged in, cant charge the device"

I'm not sure how are you NOT able to get it connected to your computer. Since i connected it to the computer, it didn't start charging but it allowed me to transfer files. And so i did. You might wanna change the cable and check if its letting you connect to your PC.
So far its working perfectly alright. I don't have a problem as such. And wait, you could install a file manager and move a couple files around. Maybe delete some files or download some files and try.
I Hope it works for everyone who's getting this problem. I know its not a hardware problem and HTC support sucks BIG time. i don't even have htc headquarters so i couldn't get it replaced, bad. but if your phone is under warranty you must get it replaced :laugh:

Hi! so you are saying that if i move some files from the computer to the phone it might get fixed? Well, i cant plug it to the computer, it just doesnt recognize the phone, if i plug it when the phone is on the pc doesnt show anything and the phone doesnt charge or anything, just like when trying to charge it with the ac charger, if i plug it with to the pc with the phone off then it shows a message that doesnt recognize the device, and the phone doesnt even charge aswell...
Right now the only fix i have found is to solve the problem of having to drain the battery in order to charge the phone, now i fixed it unticking the fastboot option in energy, now i can charge with any % but the phone must be off. Btw it gets a lot of heat while charging it this way... idk if its normal, i heard that because the aliminium case it gets more heat than normal plastic cases.
Thanks for your reply, ill try to connect the phone to the pc a few more times.
Hello guys , , I have the same problem , charging the M7 (On stock rom), I have tried many things ,roms and kernels , currently I managed to make it charge with the screen on with some conditions..
I installed SLIM ROM from their site (4.4.4) . To charge the phone with screen on I have to check "screen on while charging" (because if the screen goes off it stops charging /same thing if somebody is calling me )
To Charge my phone I just need to Reboot normally and charge it ( if you install this rom Activate the sound for the ac plug/unplug so you can know if it is charging well or not )
Eaven if i have to do these things its better then the OFF mode .
Hope It helps .
HTC M7 Only charges when it's off and the laptop can't recognize the device.
Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

It can sometimes be caused by a defective usb port on the phone, does your port looks damaged? Boot your phone in safe mode and check if its doing the same thing.
I've already done that and it doesn't work.
I really don't know what the issue is? I mean this is a perfectly working unlocked HTC M7.
I've turned if off multiple times and even wiped it clean twice. I don't know what else it could be.
I mean it's been working perfectly since I got it.
But as I mentioned earlier it will only charge while the phone is off. And my laptop can't recognized it either.
It only appears and "Unknown Device."
But even when it is off it charges for a bit and then it completely stops.
Then you see the battery logo and then it starts charging again. But it repeat that same process throughout the whole time. So, it can never reach to 100%.
As I've mentioned before I've never really had this problem.
I've been looking for hours on the internet and so far nothing seems to work. There was an app I saw on to access engineer mode or something, but for some reason I can't use that app because it says that I'm missing another application.
Any thoughts??

Hi,
had same problem.
Clearing system cache helped in my case.
Related cause for the trouble seem to be a couple of OTA upgrades I did recently.
(I was on a pretty old version.)
I noticed that there was something wrong while upgrading.
Even though the phone was connected to the charger while the whole upgrade process,
battery level went down...
The following procedure is your own risk!
Be careful not to choose any options that wipe all your data or factory reset your device.
This is how I cleared the system cache :
Boot into recovery (hold both volume-down and power buttons for ~30 seconds until menu shows - )
Press volume-down to choose RECOVERY and press power button.
Be patient ~60 seconds until menu appears.
Choose wipe cache partition and press power button.
Choose reboot system and press power button.
I hope this helps you.
Thanks

EUI - Charging only through TWRP

Hi all,
I have been using my phone (X520 on EUI 5.9.23S) for over a year without any issues and all of sudden the phone probably overheated(felt very warm yesterday and the battery was draining fast) and now it's not charging at all unless I enter TWRP and charge my phone that way but that is very, very slow and takes ages to charge.
When I try to charge my phone the normal way, the battery indicator even turns green for a split second but then quickly changes back to white and refuses to charge as if a safety mechanism is in place that is preventing the phone from charging. Also, when I connect my phone to my computer, USB modes are not coming on the phone anymore nor is the computer detecting the phone properly. (I get "USB device is unrecognized" error message)
The TWRP method is so slow and inconvenient so I would appreciate if someone can help me out here.
By the way, I am on IllusionKernel but have tried OverloadKernel as well but the same result.
Thanks in advance.

Try replacing the stock boot by using “fastboot boot boot.img” which should restore stock kernel, may be EUI isn't supporting the custom kernels well.
However I am unsure,I read about this on a form some months ago so can't guarantee this will fix it or worsen it.

Thank you for your response. I have been using a custom kernel(s) for months and this just happened out of nowhere. I will still try to revert to the stock kernel.
Might be due to battery damage , probably needs new battery.

This could well be the case but it charges very slowly through TWRP and when using the phone, everything seems normal (no overheating or battery drain) so I think, it's something else that is the issue. Also, my CDMA official headphones are not working either during the call or even when watching videos.
