My bootloader was 0.x so I tried to upgrade to 1.0 and now I think it might be bricked.
I've read LOTS of posts here, but it won't hard reset or go into bootloader. The screen shows nothing, no matter what I do. The battery is good though as it works in my friends Uni. If I plug into my PC I get 'device not recognised' error.
Anybody got any ideas at all, ie flash from SD? Is this possible. I'll try anything!
Thanks in advance.
MTTY
Find a copy of MTTY, as notes on attached txt file, and follow brief notes.
Its a way of issuing commands direct to the PDA.
If its bricked you dont have much to loose :-(
Mike
yes it's work!

Thanks Mike. But the problem is that it just won't go into bootloader. I've tried MTTY before and no luck. It just doesn't see any device connected to my PC.

Thanks for the suggestion but as said before it just won't go into bootloader. Appreciate any other ideas?
Big Yella - what does the phone do? Anything at all?
If it's trully fecked, you'll have to get a gold card or jtag interface. But is there any life in it at all? Do the lights come on when charging?
V
Vijay - the only sign of life is when I push the reset hole and the light flashes red. Also when the battery runs out completely and I plug in the charger the light stays red for about 2 or 3 minutes and then goes out.
Apart from that, nothing. The screen doesn't react to soft/hard reset or trying to put it into bootloader. But it was a perfectly working Uni until I tried to upgrade the bootloader from 0.x to 1.x.
Do you think I deleted the bootloader?
Thanks.
If it's not the battery, I think the bootloader it messed up and bricked...sorry
Sounds like the battery is completely dead to me.
Mine did exactly the same thing a couple of months ago but all I needed was a new battery. Had me very worried for a while too though.
I haven't still got my old knackered battery to check, but I would guess that you should be able to get the bootloader up while the device is connected to the charger (and the LED is on, and red)? Not sure if that will work if the battery is totally screwed, but if it does, then it would at least prove that the bootloader is still "there"...
EDIT: Just noticed that you say the battery works in another Uni - I'm flummoxed then! There's nothing wrong with the actual battery contacts/connections in your Universal is there - 'cause your device really is displaying exactly the same behaviour that mine did when the battery didn't work...

Hmmm. The contacts/connections looks ok. Do yo think its worth taking a screwdriver to it and looking further inside? (I'm more than happy to do that, its way out of warranty)
If this happened just right after the bootloader flashing, I don't think opening it up would help. I really think the bootloader is messed up.
Unfortunately I guess clemsyn is probably right. Shame though cause I was hoping it was just a power problem, which showed the same symptoms in my case.
Hi guys,
dont ask me how because I have no idea but I rebooted my phone after some minor activesync issues and my phone rebooted straight into bootloader!!, does anyone know how to get it back?
I dont mind if it has to be wiped because I can always re-synchronise my data but I'm staring at a brand new brick!!
Thanks guys

What shows in the bootloader?
Try connection with MTTY and issuing the "boot" command (no quotes).
Thanks
Dave
I know this is probably a daft question but what is MTTY?
My TP2 is completely stuck on a multi-coloured screen with information on it..
RHOD100 32MB SS-BC
SPL-0.79.0000
MicroP-Rhodium (LED) vA
MicroP-Rhodium (KEY) v4
TURBO HW/TURBO SW
TP MFG DATA
513,534 807,857
812,203 207,204
211, 859 Calibrated
What can I do?
Did you hit the vol down when you turned it on?
You can just pull the battery and turn on normally.
I may have accidentally hit the volume button, I didnt think I did anything different.
I've pulled the battery out, I've even left it an hour hoping it might drain any residual power and take out the memory but no joy.
if I pressed the volume down key and switched it on would it cause this?, I remember older phones needing a complicated combination of at least two or three buttons to be held before it would enter the bootloader.
is there a combination I could use to bring it back?

Read here on how to get MTTY and you to connect it to your PC. Do not try any of the fixes (they are for the Kaiser), I'll posts suggestions here.

Thanks Dave,
I've just downloaded MTTY for Vista (although that only says test) is that ok?

Ok... dont ask me how as I have no idea but it's just started working again!!
I havent installed anything or ran any software so I dont know why but I plugged in the USB connection and the charge light appeared, I switched it on expecting the bootloader screen but it's back in Windows!!
I am worried that this could happen again, has anyone heard of strange behaviour like this before?
Also Dave, would you be able to teach me how to fix it if this happens again please?, I have a horrible feeling this wont be the last time I see that screen... without me getting to it on purpose!
Thank you for all your help, it is really appreciated.

It can happen for a number of reasons. Normally cmonex patches the Hard SPL with some fixes to stop it happening for "Random" reasons - so Hard SPL is a good way to fix it (Hard SPL has other benifits too) when it's our. There is no set fix, different causes, different solutions. If the problem becomes common on the Rhodium, I'll do you another sticky.
Thanks
Dave
Thanks Dave, you're a star.
I had this problem on my Kaiser.
Back then, I thought that it would be a problem with the device memory (like corrupted blocks in the bootloader area).
I did the FrankenKaiser to completely "format" the phone and it solved the problem for a while, but then, a month or two later, it appeared again.
I started thinking that it was a problem with the USB connector (pins shorted). Today I believe that this is the culprit. My advice: return the phone and get a new one.
There is another topic already open... a few guys remained with zero battery while they've ran Android and they can't start the TP2 anymore. Still no solution by now...
I am in a similar position... my phone charged and started... but my USB connection to the computer is dead (no "unknown USB" or something, just plug in and nothing, just charging...)
Believe me, I've tried 3 different computers with XP, Vista or Windos 7, and three different USB cables...
Guys, I really appreciate your work and I am a real tester of new mobile things... but, please, help me. I've already made 3 hard-resets and still nothing, and... I can't instal another ROM because I don't have a USB connection. I have windows 6.5 original HTC version.
Tx in advance.
And, by the way,,, PUT A MAJOR WARNING TO THE GUYS INSTALING ANDROID ON TP2... NOT DRAIN THE BATTERY!!!!!!
Hey
This is also happening to my device. I'd appreciate any advise, help or just someone telling me, to stop being a nerd and to go and buy the Desire.
Thanks in advance.
hi realy i now battery gets realy hot and drains it fast i think its nog good at al for battery and some maybey whil get a dead battery or it has something to do whit your usb in its own or driver malfunction
ps realy think buying the real thing is still the best to do thats why i am gone buy desire
I bought a cradle with sync/charge + charge extra battery from ebay. That saved me a couple of times. Don't forget to add a Battery to the order. I bet your battery is just fine. You just need an external batterycharger.
Just to be well understood.
The phone is going well, in WiMo 6.5 or Android, I can charging the battery with no problem, but... I can't connect it to any PC... that's a real problem...
Is it any posibility to reset the USB driver of the phone or something?

what rom are you using?? (sorry see that you have original HTC version) and did you try to convert your phone back to factory defaults tru the option within the system settings folder???
did you try to boot to andriod again?? with usb atached? and without?

I have wiMo 6.5 HTC original version. I've tried to convert to factory defaults three times... the same.
I did boot again Android with USB and without attached... still nothing...
I suppose it's a driver issue (it's stocked somehow), but how can I get it in the normal state on another method, another than the tried ones?
I really appreciate a helping hand...

For me at least, I don't get any connection via USB to the PC. In bootloader my device only has "Serial". As this condition seems to be permanent, I can only flash from SD card now. Is it really not possible to change from Serial to USB in the bootloader window?

I'm now on the stock HTC 6.5 ROM with Sense 2.5, localized Danish.
Not really sure, what you mean with the system settings folder. I'm not a noob, since I've cooked and flashed a lot of ROMs, but that seems like a setting I haven't heard of. Please enlighten me.

ok well first of all sorry for late response was really busy with work and all.
ok second i didnt build/create or ever attempted to figure out how the haret loader works and how its possible to run andriod on TP2 but i do have quite some exprience with software and loaders. so my question about what happent if you booted andriod again was because i thought if it screws up your settings under WM6.5 and after that fails to boot the right way.
maybe after another boot which is going fine, it auto-corrects the settings under WM6.5 but that was just a wild guess.
ok third about the system settings option stuff
i will try to enlight you i now run Cell EVO v7 and before that i had the Energy rom WM6.5 both had these function but with deferent names.
if i press start-flag at the bottom left in the home screen. and than go to "Settings" button and after that i press "System" than there is an option called "Clear Storage" and i removes ALL settings and changes you made and returns everything back to the first install moment of that ROM. i forgot what this was called under the Energy ROM but it was also under the "System" button.
hope it will make any difference for you good luck!

My friend, I tried the both hard resest and "Clear Storage", I think the both are basicaly the same. Anyway, none of them produced any positive feedback.
Guys, reading this forum it seems that a LOT of people got a LOT of problems after draining their battery under Android... it seems that I am a lucky one only USB connection got dead... a lot of other guys just got their ... TP2 dead.
So.... nobody seems to have any ideea about what is going on!
Guys, I really appreciate your work, I hope you know that you are experimenting on thousend of mobiles phones around the world... and all of them are exposed to get malfunctioned... some of them for good.
Please, if you get us in this circle of Android... just help us! otherwise I think you are not so well intended...

Nobody has had a "dead TP2" from the android OS. It drains the battery very hard, sometimes yes, but if you know anything about batteries, this also means that the battery is going to need a very good charge again. New batteries are designed to have minimal battery memory anyways.
I had to return a ATT Fuze for the USB connection failing while I was using strictly WM, but i didn't blame it on WM.... I feel like a lot of people are starting posts about these issues who are making huge jumps to conclusion. Is there some hard solid evidence this is even happening? Read these threads on this forum about battery "issues", and a few posts down the line the person is saying "ok, i think everything is fixed, i just needed to charge it" or something along those lines.
I got my external charger today. Plugged it in & left it charging for an hour or so. Got into bootloader and successfully reflashed. Boots fine. Problem solved!
My guess is that Android doesn't have a reserve in place so your battery doesn't get so low that it can't even reboot.
OK, guys,I went at HTC service, after 3 days the phone is again in good condition.. They replaced the mainboard!!! SO, TAKE CARE, ANDROID KILL YOUR PHONE. I SEE NOBODY PUT THIS WARNING ON ANDROID THREAD, although I mentioned it from the very begining.
Regarding me, I will calm down with Android on my TP2... Anyway, what's the point, HTC Sence is the best interface among all the mobile phones. See you on WM threads, bye bye Android.

I find this to sound slightly ignorant.
You're on a website that's all about doing things to your phone that the supplier never intended, jamming things into it to make it do what it never said it would do when you bought it.
The guys here at xda-dev give us some amazing things to move beyond the limits of the phones out-of-the-box, and pretty much everything posted on this site comes with a "do it at your own risk"-warning.
Now you're accusing these people of having "not-so-good-intentions"?
You came to the site, you decided to use what was here knowing full well what that means, so the risk was yours to take. You knew the risks when you signed on, and if you didn't, you weren't paying attention.
I understand and applaud that you're trying to warn people of the consequences, but please don't act as if you shouldn't have known that everything you do with things supplied through this site wasn't completely your decision.
If you want to make absolutely sure your phone isn't at risk, don't tamper with it.
You're right, I was informed about the "do-it-on-your-risk"... and I can't accuse anybody. What I want to do is to put an additional warning" BE CAREFUL, DON'T DRAIN YOUR BATTERY", there are enough warnings on this site of people that got in the same situation like me. Take care of our friends!

Have drained my phone fully MANY times with Android, WAYYY too many to count, and I have never had it kill any hardware. Being on this XDA Developers web page, the "warning" should be unspoken. As many have said before, WinMo does not let your battery drain down all the way to 0%, Android does, therefore the handset will not boot, until the battery has stored enough power again. This is easily fixed by plugging it into a WALL Charger, not a USB Charger.
wow... i thought it was just your average "whoops, bug" moment.
whenever it happens to me, i simply unhook the usb from the phone, hit the reset button on the phone, let it boot all the way into wm, then plug in the usb... it works fine after that.
best of luck
Dear all,
Require your help in recovering my Xperia Arc S from boot loop.
The phone had issue in switching on bluetooth. So i thought of restarting handset.
After restarting handset, the handset was stuck in reboot loop.
So connected the phone to pc companion and upgrade phone o.s to 4.1
It worked for 2 days. Now when i tried to switch on bluetooth from settings; phone got restart and stuck in reboot loop.
Kindly help.
Thanks in advance.
There's a thousand plus threads on boot looping, give one of them a read.

Dear XperienceD,

If you know any thread where proper solution is provided, Kindly let me know.
Thanks.
Since you repaired it with pc companion, and still get bootloop after enabling the bluetooth, i think this is caused by a hardware fault

Try this, helped so many times with Arc S:
- turn off your phone
- remove the battery cover
- remove the battery
- put a small piece of paper between the bottom edge of the battery hoousing and the battery (the side opposite of the battery connectors, so the piece of papper pushes the battery towards the battery connectors)
- put the battery back
-turn on your phone

I had similar issue on my Arc S, and this helped. It seems that there is a loss of powerdue to bad contacts, and the voltage level drops so the phone goes into restart loop. Try it, can't do any harm
I had a problem earlier (some 10 months ago) when i turned on blue tooth it went on rebooting, I tried to get into settings and switch off the blue tooth which was not possible due to fast rebooting. Then I read read in a forum to leave the mobile to reboot for nearly 8 hrs or so, so I left it like that (to reboot continuously) for more than 6 hrs, then it became normal with blue tooth going off (I think so) and I went to settings and then to backup & reset (I think I lost some data during this). From then on I never tried to use blue tooth.
Again today (19 Nov. 2015) I wrongly pressed blue tooth instead of wifi, then again the problem of rebooting started, I was upset thinking of shunning this mobile once for all. Then suddenly I searched in web and got this link :xperia-arcs-auto-reboot.blogspot.in/2012/08/sony-ericsson-xperia-arc-s-auto-reboot.html , where it is asked to keep the battery tight in it's place to keep good contact with its terminals in mobile. Before doing this, I took a conductive metal (a small knife) and I shorted all the three pins in the mobile where the battery touches to give power. *WARNING: NEVER TRY TO DO THIS IN THE BATTERY*. Then placed a piece of paper in the back of the battery and inserted in the slot. Then I switched ON and it started and the boot was holding for some time (say 30 seconds), with in which I went to settings and switched of blue tooth and switched off the mobile. Then removed the battery and inserted again with the same piece of paper and restarted, now it's working.
In my experience, this mobile is having problem both in the battery placement for tightness and in the blue tooth software also. Otherwise this is a good mobile. Thanks for the forums which helped me salvage my mobile with many important contacts. I share this here out of gratitude for these forum. Otherwise I would have to spent a lot for software reloading if I went to authorised or some dubious service centres.
I have some questions. (Copy from the old thread)
1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.
2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?
3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.
4. Since a few days if i turn off the key normally all lights form the radio and display shut down. Additionally board computer shut down too after a few seconds. Now the light from the dvd tray is on and board computer too (after a lock from the car too). I dont know why but I don't know if that is so good (Battery).
All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom? That is really crazy, because it's only since a few days. The days before it works perfect.
I have JY 2.73 with the Malaysk Rom from September (1024).
Thanks
Update: Now i installed 2.59 JY and tried again. WiFi will always gone with no bars. So i turn off and turn on again. At the most cases it works. But the problem is here again. The same with the touchscreen crash. 3G doesn't work. always no bars.
So the previous MCU doesn't work again. Maybe a software error.
Could you please try to measure the voltage alignedto the HU while you encounter those problems? I rellay mean at the radio side (so not at the battery poles).
Such issues could be lack of voltage. If not and flashing does not solve it could be a defective unit.
Just to ensure: You flashed Firmware AND MCU? AM I right wit this assumption?
If not: Try to flash a new ROM first (probably try Malaysk ROM)
Btw: Moved to Q&A

Sure. I have Malaysk Rom and the MCU JY 2.59.
you would have to get amulti- or vooltmeter and attach that between plus and ground pins at your HU.
If you don't know how you should eigther try to follow another way first if possible or ask someone to do it for you (it's electrics)

Thanks. I ordered a multilmeter. Maybe it's the battery. At the moment the car works really hard if I start it. The radio takes so much battery but the radio is off. So that can be the problem.
low voltage can cause many weird problems but you have to know a new battery might not solve your problem!
If you have low voltag while the engine is ruunning then you have a different problem. eighter there is a connection issue somewhere on the path the energy takes from battery and generator to the HU or your generator might have a problem. But that is open to check when we know if it really is a voltage issue.
Hi,
i'd like to give you an update for my problems. Since the last days I have the problems, that my car didn't start. Now we see, that the battery is nine years old. Now I charged the battery (tomorrow I'll get a new battery) and the first test shows WiFi works for 3 minutes. I know - that's not a lot, but I only can try if I have the new battery. 3G doesn't work - always the same. But that's not so important for now.
At the moment I don't have the volume error. I will test it, If i have a longer car drive.
The problem with the touchscreen is actually. Since a few time, after few minutes the touchscreen is bricked and I see the points that i touch it, but I can't click anything. If I touch ten times, twenty times or often then radio shut down and shows the boot logo... forever... it doesn't boot again. So I have to make a hard reset.
And the last point with the light board computer and the light dvd slot after plug off the key is actually too. It don't shutdown the lights on the standby time from 10 minutes (set it to 10 minutes). I know now, that I can shutdown it completely if I press the volume button for 3 seconds. Than it's turn off. So it's a setting problem from the firmware?
Today I plug in the key - nothing. Radio doesn't start. So I looked behind the radio and saw, that one thin cable is not in the wiring harness and I can see the wires on the cable. So I tried to put it in the wiring harness again. I hope it works longer now. I wrote carjoying and ask for a new wiring harness. Maybe all problems will be fixed, If i have a new.
Hello again,
now I've got a solution for the wifi problem. I've tried to connected wifi - i Known that doesn't work only few seconds and after a few seconds it shows 0 bars on wifi... now I disconnected my 3g stick and LOOK it works... full bars, no losing connection. I connect 3g again and the same problem after a few seconds.
So th3 3g stick (E1750 from Huawei) makes some problem OR the usb cable?
Huawei E355 also not working. Same connection problems with malaysk rom MTCD
Any suggestions?
