[Q] Phone won't charge nor Fastboot / Flashmode - Xperia Arc Q&A, Help & Troubleshooting

Hey everyone,
after dropping my S3 two days ago which lead to a highly damaged screen (not working anymore) like two days ago, I got a new Arc S from a friend. As I said, the phone is new, and unused.
I've been trying to update to Android 4.3 yesterday, followed some tutorials I found here. I installed the Dark Kernel trough fastboot, then tried to flash the Dark JB rom. But nevermind, this didn't work, so I decided to flash back to stock kernel + rom.
I succeded in doing this, but had the, as I see, common 100% battery problem. Didn't think about one thing. The phone won't charge when the battery is on 100%. So my battery went empty, but whenever I want to charge it, it doesn't because the phone kinda thinks it is on 100%.
Now, I wanted to wipe the battery cache, which isn't possible because I cannot load fastboot mode, and what I've been trying aswell, cannot load flashmode neither.
I don't know what to do to be honest, I hope some of you guys can help me out!
regards

The battery issue can usually be solved by flashing new kernel(s), then returning to the original one.
If you have another Arc (S) available, charge the battery there, then put the battery back and then try to connect. Phone can not be detected due to no power at that moment.

At first, I'm sorry for those awful grammar mistakes I made in my first post
I do not have another SE mobile available to be honest, but I understood what you mean. Thanks for answering me this fast.
I charged the phone for like an hour when it was turned of completely, so now it is up again (idk for how long). Trying to enter fastboot now.

[Q] Bricked x10 mini. completely dead except for red led

Hi i had just flashed my phone back to standard rom with seus, and had rooted and was removing bloatware.
i used ADB Mask Controller for removing files because it was faster, but on the list of non essential apps i chose the ones a i wanted to get rid of, and accidentally clicked "delete all", because i thought it meant the all the files on the list. after that, i rebooted and the phone was dead, seus cant find it or anything, but now a day later when i press the power button, the led on the front blinks red a couple of times...
is it completely dead or is there a chance of getting it up and running again?
try flashtools
you should try bin4ry's flash tools it works most of times, there are a few tutorials around the forum but in general you just have to turn the phone off completely start flash tools select flash, select firmware and connect your phone pressing the back button just like in seus , also try posting problems like this in the general section, i know i'm no mod, but it helps keeping th forum clean , but don't sweat it, i think we all have done this when we started (i know i did XD)
Sorry if i posted it the wrong place, didnt think of other places cuz my bookmark leads me there.
Thanks for replying, but my problem is that i cant turn it on, when i press the power button, the only thing that happens is the led flashes red a few times.
Blinking red means that battery is empty. You can to charge it a bit with AC charger and then try to boot the phone.
yeah, sorry for the scolding , and i think it flashes red a few times because the battery drained, and flashtools is a pc program like seus, you don't have to turn your phone on, you connect it turned off, it is for flashing firmware to your phone and i recommended it because i think the reason your phone died is because of the missing apps, think of flashtools as a much MUCH better program for repairing your phone than the pc companion one or seus
also, here is a link to the main post for flashtools

edit: wiilweer beat me to it , and great port by the way, haven't tried it myself because my xrecovery is not working, but it looks great, specialy the 1000 in benchmark =O, excellent work men, thanks for the froyo port and your work
Thanks ill take a look at it again, hadnt seen the thread u linked now.
its been charging for a few hours and still just blinking... and it was at 100% when i started messing it up
maybe it is a stupid thing but...
have you tried
1) center hardware button + power for a few seconds?
2) disconnecting and reconnecting battery?
in the worst case you can try charging it with an external charger
but this means disassembling your mini:

Happy flashing.
Looks like its working now.
it wouldnt charge the battery, so i took the battery from another x10 mini, and then i flashed it. pc companion could find it and flash, with power from another battery
Dunno why it wouldnt charge the battery, maybe i deleted stuff that had something to do with power management.
Thanks for helping, i was already looking to buy another phone.
Thread belongs in the general section.
i have the very same problem !! ... WHAT did u dooo 2 fix this ?? am hopeless
try charging it and not with usb, if it wont start, try an external power source.
does it blink red when u press power botton?
Just want to share this, I do not create this procedure, and I forgot where I seen this.
1. Open SEUS, one it ask you to disconnect and connect. follow the next procedure.
2. Connect your X10 mini or Pro. Disregard SEUS Procedure
3. Press the Middle+Right+Power Button at the same time.
4. Once Screen Goes Blank, release all button except the middle.
5. now you could Update using SEUS.
Hope that help.

if the procedure above is not working you should try to recharge the battery or use one from another mini charged before trying that cause if battery is drained you won't be able to repair firmware...

what is it doing?
I spent the whole yesterday afternoon and night and this morning trying to figure out what happened to my 'dead' x10 mini.
It has been lying there for over a year since I last tried reviving it.
Long story short, I forgot that I had flashed miniCM kernel on it. For some reason it just entered boot loop with Sony Ericsson logo and restarting and refused to charge. Then tried SEUS and Sony Update supposedly 'flashed' successfully, but I still could not get it to boot nor charge. Flashtool also was used to try a couple of other ROMs, until it dawned upon me I should flash back miniCM ROM since I think I had last used it year ago.
Voila it worked and I pressed BACK several times while the nAa logo came up. CWM was back. I jumped for joy... now I'm charging it and also downloading miniCM10 with gapps.
I really hope this helps - and that it would work for some of you out there in deep frustration. All the best! :good:

Looks like I went ahead of myself.
It managed to stay on in CWM... and I even managed to install update.zip and gapps, but once out of it the phone simply refuses to boot.
SEUS managed to flash stock ROM on it as well. However, even after leaving it hooked to the USB overnight (it only gets warm from this, not wall plug charger), it constantly looping in a flash mode (green LED) and then low batt mode (blinking red LED), it failed to boot up successfully on its own. After flashing the sony ericsson or custom ROM logo, it would go into a boot loop until the battery drains. Upon connecting back to wall charger, the first time it actually flashes real quick split seconds battery indicator of 2 out of 3, then go into the said boot loop again.
I really dunno if the battery's fried or did I do something wrong to hard brick it.

Hard Brick in my Defy...Help-me!!!

Good evening everyone,
I own a Motorola Defy, and tried to put the ROM "For Adlxmod Froyo Defy, "but I had the UK firmware 2.51.1.
It was there that a lack of attention, my phone now does not care anymore.
He only gets a white LED lit in front of him and does not happen any more, nor even acknowledge again by RSD.
I read in several places that this is due to firmware 2:51 and I believe I have given a HARD BRICK on my device.
Has some way to fix my phone without having to take it to an authorized?
I thank everyone's help,
Felipe

Thanks, I managed to settle with the tip given!
Hello Everyone,
My Defy run out of juce with a special 3400mAh battery from china in the night. When I came home I changed the battery (the stock battery) which was fully charged. After that the defy was stuck in a bootloop (cm7) but i did not recognize this for a couple of hours. Because of this bootloop I removed the battery and put it in again from that time on the defy was dead. Maybe I did not wait long enough - I mean I saw the bootloop and thought 'crap' took the battery out and stuffed it right in again (I was a bit frustrated). Maybe i should have waited at least 5-10 seconds before putting the battery in again?
I tried to get access to the defy by RSD lite. But the PC does not recognize it. I got a white LED by connecting it to the PC. The defy is recognized only for to seconds and than disconnects again.
I tried to flash via sbf_flash on ubuntu without any result. The defy is simply not recognized. Only white LED. No Bootloader, no recovery, no logo.
Has anyone a suggestion? Is there a possibility to get acess to the defy to reflassh everything. Since the white LED is active there has to be a way. What about JTAG and riffbox? could this be a solution and if yes - how ?
I bought a used iPhone4 last week. But honestly: I hate it!! I do not like iOS, I dont like the edges of the iPhone - it is so uncomfortable to hold it in the hands. Wifi connectivity and connection is catastrophic. I will sell it a.s.a.p. again.
I want just my beloved defy back - the only phone I ever loved !! I appreciate any suggestions - thanks in advance !!
Your "special" battery is not that special afterall
What happened to your stock battery? Just get it charged - ask a friend with a Defy to charge it for you or do the McGyver trick, in order to fire it up again and then flash your stock SBF via RSD Lite. Calm down - Defy is like a Terminator and is immortal (as long as you don't kill it by flashing wrong SBF )
Thank you for the reply. However I have a dockingstation for the defy with which I can charge the battery without the phone. The battery is full for sure!
Hope you are right that the defy is like the Terminator - I have not lost hope yet.
Any other suggestions ?!
If Defy doesn't even get into bootloader, this means there is no juice in the battery. No matter what crap one would flash, bootloader is ALWAYS accessable! That's the beauty of the locked bootloader - you can't kill it! So as long as there is charge in the battery, you can always get into bootloader (Vol up + Power) and flash a new sbf. Peace of advice: don't trust your cheap, no-name, chinese battery. Use the original one, charged in another Defy phone, so you can make sure it really IS charged. The fact you left it in an external charger, doesn't mean it is charged - battery might not be working, charger may not be working, or both at the same time might not be working. There is no reason not to get into bootloader if there is charge in the battery
Cheers!

It's blank screen problem, happens when you flashed an SBF older than your previous one.
You still can get into Bootloader, just nothing on screen but it's definitely in there. Then flash the right SBF, the same or higher build than your previous stock rom successfuly to fix it.
Which SBF are higher than other? It's about Bootloader(BL) version, read here. http://forum.xda-developers.com/showthread.php?t=966537
If not sure, try DFP-231 builds, it's highest BL version to ensure fixing this.

Look, I've suggested to one who use Defy+, so I said he should try DFP-231.
But not for Defy mb525, you shouldn't flash DFP-231 or any 2.3.x SBF files to your mb525...
Now you've stuck to Bootloader V.7 and no way back.
What's done is done, stick to that DFP-231 SBF you've flashed for now.
Did your flash finish with "Finish/pass" or "Please manually power up phone"?
If it Finish/pass then try again on Stock recovery, you almost there.
But if "Please manually power up phone", means you're not yet flashed your phone completely...
So do this, http://forum.xda-developers.com/showthread.php?p=38187413

[HELP] Bricked, almost dead Defy+

i bought this Defy+ just a couple of days ago and i was trying to get CM7. I struggled to root it but i achieved it. I wiped and did all the procedure before installing it, but i didn't had enough space on my SD, so i rebooted and booted like a brand new defy, going through the Blur config and everything... So i went to Recovery again, but at this time i forgot to do the wiping - which, i guess, led to a brick.
So i managed to get a .sbf to flash it.. What i didn't realized is that the .sbf was a custom, so i guess this ****ed up my phone even more. And so i went on trying to rescue my phone but this time i couldn't complete the flashing process, i wasn't able to perform a downgrade - i guess. After this, i got a non-rootable .sbf and began the flashing. The process got stuck on some message at 0%, then i disconnected the phone.
When i was able to download a stock firmware, from the .sbf thread, the phone wouldn't reboot when RSD asked, it didn't turn on again. So i tried to re-flash it, same .sbf and now i'm stuck with this situation: the pc is not recognizing my phone, i have a black screen - not even the Bootloader error screen is appearing and i'm here, begging, for someone to help me. is it dead? can i get it back?
HELP, PLZ
Is there any juice in the battery left? Does the phone even turn on or did you just drain all of your battery? If so, you have a couple of options - do McGyver or find somebody with the same phone and ask him to charge your battery and then start over. I would strongly recommend you take the second option.

Led is always on when connected to the PC - it means nothing. If it doesn't turn on, then your battery's dead. Find someone who has the same phone and can charge it for you.
I think there is no problem, but you flash older firmware, which is probably due to the 7 bootloader does not go up.

If it gets past the red m and just keeps playing the android animation then simply pull battery hold volume - put battery in and keep volume - held when you get the android and the triangle press volume + and - and wipe all, should boot, unfortunately you've just flashed the un root able sbf and are stuck on moto standard

nevermind, i flashed other sbf version and it is now working; too bad this version isn't rootable

Hi guys.
Last night has been a nightmare for me, I have to say. My Defy has been suffering recently from battery fatigue - the battery holds charge for about ½ an hour before I need to plug it in again. At the time, I was running CM9 (Epsylon's) so I thought I'd try downgrading to CM7 to see if it was software or hardware.
This is where the trouble began.
I faactory reset the phone and flashed the CM7 ROM I was going to use (http://forum.xda-developers.com/showthread.php?t=1604501) then hit reboot.
My phone got stuck on the M boot logo. Great. Back to recovery, I wiped all cache etc and rebooted. Still the same. Back to recovery and I tried the whole process again. Still the same.
By this point, my phone was losing charge, so I left it to charge a bit (plugging it in from 2% charge takes it instantly to 60%).
Then I retried the whole process again - still the same.
Okay, it's getting late now and I'm starting to panic. So I download a stock ROM (T-Mobile 2.2.2) and flash it using RSD Lite. Looks like it's going well, until it tries to reboot me - stuck at M Boot logo.
Now, I can't even switch my phone on to get it to the bootloader. I've tried a different battery too, and no joy.So now I have a well and truly broken phone.
From my knowledge, I have two options here:
1. Try the Macgyver fix method. I'm not confident doing this, and don't even know if it will work.
2. Take my phone back to T-Mobile and hope they don't notice what I've done.
I'd appreciate some help please if any one is able.
thanks.

ok mate
right the mcgyver trick works a treat and is surprisingly easy. i wasnt keen on it but it works and is not hard although it is fiddly and if you are anything like me it will take a few attempts to peel back the shielding and expose the wires and then get them in place.
i found the best way to get the wires in place was not put them under the battery as the guide suggests but instead just put the battery in as normal and have the wires in at the very end. you will understand what i mean when you start but i have decided to take a photo and you can see what i mean here
http://sdrv.ms/OPDczX
everything you need for that this section of the recovery is here.
http://forum.xda-developers.com/showthread.php?t=892026
then you need to flash the sbf again. the one you have already flashed is fine and is the one you need so use that. (if for some reason it doesnt work after what i am going to tell you then ask again on here before you choose another).
next follow the guide to un-bricking your phone (linked below). if the phone wont boot and gets stuck after you have flashed the sbf you need to boot into recovery and wipe the data/ cache. reboot and all should be ok.
so follow the guide to the letter but when/ if (the phone wont boot past the moto logo) follow step 8. however you will find that when you press power on/ volume down that instead of motorola recovery you get a droid with an exclamation mark (this is ok so dont panic). to get into stock recovery from this position you need to press and hold down both up and down volume buttons at the same time for about three seconds and viola. then you can wipe and you should (fingers crossed) be good to go. if you dont understand anything then ask but it is relatively straightforward and if you do what i suggest above then you should have a working phone in next to no time.

good luck
Thanks for the prompt reply, I feel more confident doing this after reading that. Unfortunately I've no spare USB cable to try this with at the moment, but having looked further I've noticed my battery has a bulge in it, so I doubt there's much point in trying this with this battery.
I did however successfully manage to flash the sbf file (according to RSD Lite) using my friend's battery - but the phone still doesn't boot. Given that my phone isn't going to be right with the current battery - I think my best option now is to take it back to T-Mobile, tell them the battery has done some damage.

did you wipe the cache/ data after you flashed the sbf? if you didnt you may want to give it a go before you send it off. it may spring to life once you have done that.
I don't get that option - the phone doesn't reboot. RSD Lite said it did, but all I actually got was a blank screen.

It looks real bad. You sure the battery didn't die in the flashing process.?
Also try booting into recovery and do a wipe.
It's entirely possible that the battery died during the flash.
I cannot boot in to recovery - the phone doesn't get that far!
I've sent it back to be repaired. hopefully they'll do it under warranty, but if not it's only going to cost around £60 to buy out the remainder of my contract so if the repair costs more I've got that as a backup option.
Thanks for all your help guys.
You can cut an old wall charger but if you can't measure the voltage to know what wire have 5 volts and 0 Volts , and you can hold the wires 5V to plus on akku and 0 to minus and the supply would load..... you can left the batt out of the device...
Wait 10 till 15 min ,for save check if batt getting hot, boot into stock recovery and factory reset your phone
If you can't enter recovery you should be able to enter boatloader
If there is battery low can not program ..load akku.. or ready to program which means .... flash rom with rsd, factory reset , reboot, have fun
i did this two times, flash with low batt one of with not loading batt in dev - i charged with Nokia wall charger cable
If only battery is too empt and briked batt loader.......

so, here's my update.
You will recall (see two posts up) that I gave my phone back to T-Mobile on 20th August for a repair. I got my phone back today (+18 days). Here's how it went:
Day 1
Took phone to T-Mobile store. Informed them my battery had a strange lump, which I suspect had fried my phone somewhere. They advised they would send it to the repair centre the following day. No courtesy phones available so I'd be living in the 1980s for a while.
Day 10.
Phone actually arrives a the repair centre. I have no idea where the repair centre is, but I'm guessing really really far away.
Day 15.
Repair centre advise my battery is faulty and to replace would cost me £26.40 for a genuine Motorola battery. Advised repair centre that I told them my battery was broken, and asked why it took them 15 days to repeat that back to me. Also advised them I would rather by my genuine Motorola battery from Amazon for £11.95. Gave them a link in case they want to update their price lists.
Day 17.
Repair started on actual phone.
Repair finished. Yep - the repair took less than 24 hours.
Day 18.
Phone returned to store. it took 24 hours to get there, so I'm assuming the post travels down hill only on the way back.
Picked up phone from store, all set to complain about poor service etc. Noticed brand new battery I hadn't paid for sitting in the returns package. Kept quiet. Left store promptly.
So now I have a working Defy once more (Hurrah).
Obviously I've rooted it already in order to get Titanium Backup to restore all my apps.
Now I have stock 2.2 Blur running on my phone (Boo!), and with only a few months remaining on my contract, I'm not sure if I want to risk loading a new ROM again (I'll reread this once I've loaded a new ROM next week, for sure).

[Q] Phone won't power on. Bricked?

Hi all,
I was having some random reboots on my HTC desire Z lately and decided it was time to try a custom rom. I followed the right steps to first downgrade to froyo, which was successful and next rooted the phone, which seem to have worked as well.
The next step was to get into recovery mode to install the rom, but I did not get to that. I took out the battery while it was still on to power it off, but then it did not power on anymore. Also connecting the charger has no effect at all, so it sure seems to be bricked.
Does anyone have a suggestion on what I can try, or what happened to it?
The way I downgraded and rooted was by using Strawmetals guide which can be found here:

and was suggested in this thread:
http://forum.xda-developers.com/showthread.php?t=1178912
I carefully completed all the steps, checked the MD5's etc. and made sure the notifications/verifications I got back in the process were correct..
Also, I wonder if I would run into problems if I send it back in for warranty. If I can't get it to boot, will they? And next they will probably blame me for rooting, right?
Regards & TIA
Yes they gonna blame you for rooting. I was had a same problem, no boot to recovery. I solved the problem with install 4Ext updater and fromit install 4ext tuch,and now I can flash roms. Try to find a charged battery or put yours into another phone and charge it. If I understand right your battery died?!

Sounds like it might be bricked mate, same thing happened to me... 3 times. They probably won't be able to get the phone to boot, where did you buy the phone from? My second one was from Vodafone with a warranty, when it bricked I took it in, they plugged the phone in and left it for a few minutes and tried to power it on, tried a different battery (All things I already tried) to see if the device was showing any signs of life, it wasn't and I walked out with a new phone. I doubt they'd be able to bring it back to life to see that it's been rooted. You COULD connect your phone to a car battery and fry it, tell them you went to sleep and woke up and the phone was very very hot and it burnt your hand and melted the charger cable, not sure if I could recommend this, never done it myself... but if you have no other option.
These were also the options I considered. Got to give it a try with a different battery, if I can find one. If that doesn't make a difference, I'll just hand it in and see what they have to say, as there's nothing else I can do without being able to power on the phone..
All of a sudden the phone started working again . And afterwards I was able to complete the update to Mimicry 1.5.
Strange problem, as the phone seemed to be dead for hours.. Hope it doesn't happen again!
