why dont you try to see if LG would fix it. theres no tot or kdz to disablle big cores..
or maybe search on baked motherboards it may work. maybe for a while..

Even if this works, and it has been known to work, it will result in greatly diminished performance on the part of the phone. You'll probably want to get a different phone after recovering the data.

Depending where you bought it LG will repair it with proof of purchase.
I bought mine from ebay and purposely made it bootloop so LG cud replace motherboard.

Hello, a few years ago I successfully rooted Mt LG G4 H811 (T-Mobile) and everything was fine, except for a strange issue of not being able to boot into TWRP except by performing a button assisted hard reset. Then one day, as the old thing was grumbling through its routine, the signing remained. I then pulled the battery and permanently ceased it to function at all. Until this very night, more than two years later. I decided for gits & shiggles to plug in the charger and lo! Out started to take a change. Sorta. I knew it wouldn't fully boot, do I did the ol pill the battery truck and boot to recovery manually. I made it to the factory reset screen and moved the cutie the the "yes" position, but the power button would not engage the reboot. I tried several times with no luck. In fact, its lying here beside me, mocking me with that "Select yes to delete" line.
Any ideas whatsoever??

I've had an experience when flashing my phone where during the flashing process the battery gets sufficiently depleted that it won't turn on after the flash completes. During the flash process, the battery does not charge, and the reading and writing to flash consumes more power than normal operation.
When the Wizard battery gets depleted, it will not take a charge without some serious effort. I would plug it in to the charger and leave it for at least half an hour. Then, with the power adapter still connected, attempt several resets using the soft reset button. There was a time when I had to do this several dozen times before it "took" and was revived.
You can confirm whether it's a battery problem by trying another battery. Perhaps you can stop by your carrier's retail store and ask to try a battery. If it powers up, then tell them your battery went bad (not unusual) and they may replace it for free.
Thanks for the advise, i ll try that. I knew i could get some help from this forum thanks again guys.
went to the tmobile store tried a new battery it still wont come on. I guess have to call HTC on monday. Might have fried te phone.
Called HTC support and they do not support the xda mini s. Anybody have a suggestions or any third party vendors who can help fix this phone. Please advise.

Maybe if you weren't so sarky people might want to help...some more info might be good. What bootloader from / to and why? Does a computer recognise and install it, what happens when you run a rom update etc etc.
If you have destroyed the bootloader you will need to use JTAG to reflash it and this is not something you can do at home with your own PC so you may have to pay a service centre to correct it.
Richard
I was not trying to be sarky about it. I just need help. I downgraded the ROM from the 2.21 version to 1.X version. After the downgraded the phone booted up and it got stuck at the initail ROM screen. I tried reseting it a couple of time and it kept coming up and it gets stuck from on the ROM boot up screen. So i took the battery out and after i put it back in its not even coming up. There is absolutely no power. Im willing to send it any service center i just need info on where to send it to . HTCUSAINC says they do not support 02 devices. Thanks for at least responding to my thread.

HTC USA probably say that because they are contractually obliged to.

OK, who are i-mate's service agent in the US? Ring them. Explain you know how they don't service the XDA mini s, but it's a JAMin or whatever, and you're over from the UK where you work etc so can't send it back to o2 immediatley, a rom upgrade has gone wrong and you've corrupted the bootloader, you have downloaded the rom files and will strip the phone to the circuitboard if they would be so kind as to flash your rom file on it via JTAG if you made a donation to the charity of their choice etc etc.
So make it out that they have to do little work other than plug the JTAG onto the board and click 'ok' and you may get away with it.
If they do go for it, strip the phone, send the extracted rom files on CDr, thank your lucky stars and don't do it again. If they don't go for it, try the next HTC device service agent you can find until someone does.
Although people have JTAG equipment outside HTC the contact points are not labelled / listed in the service manual so you need them or their authorised agents to be able to do this.
Richard
Thanks for the advice you have been a great help im going to look for a Imate service center in the US. thanks again . Has anyone ever had any work done by the pocketpctechs.com please advise

I don't know if PPCTechs have JTAG capability for wizard. Ring them and ask. If they say '"huh? all our boxes have tags on them sir" or similar walk away...
You need someone that not only has a JTAG flash kit but also knows where the testpoints are on the wizard board. I don't sadly :-(
And I really would offer to strip the board down before sending - that's an hours' labour in some places!....

Unless you have a specific reason not to send the device back to o2 why not ring the UK XDA helpline for a quote? They do out-of-warranty repairs. +44 808 100 3427
If you are the original purchaser the warranty should still be valid - just don't mention you tried to flash it, says it stopped working.
Shipping insured to the UK should be no more than $25.
Richard.
I might just have to do that . It was a gift , but i know want the person to know that i tried to flash the phone. But at this point ill rather send it back to O2, than go thru all this stuff. Thank you soo much for ur inputs.

Hello Richard!
Could you please tell me more about JTAG? What does JTAG stand for and what JTAG can do. Its unlucky that now i have a dead O2 MiniS like Gambino because of doing the same thing he did (downgrade ROM). Will my phone become alive if i change the Flash ROM Chip?
BR
yes its unfortunate . I was trying to downgrade the rom. Whats exactly happened to yours. Has anyone else haad this problem and if you did were u able to revive it.

I did use the newromupdateutility_wizard_noid.exe with custom ROM (Button's) to flash my O2 Mini S (it was with German ROM 2.21 and i wanted to downgrade ROM in order to unlock CID and reflash with English ROM). The process went Ok and when the phone restarted i got
IPL 1.0. xx
SPL 2.21.xx
OS 1.54xx
and a boot screen with a glass of beer !!!!
Then the phone hang up, i think because of incompatible SPL and OS
I took out the battery trying to get into bootloader and reflash with another ROM but the phone did not power on. Now its totally a DEAD BRICK.
yup thats the same thing that happened to me. Anybody else have any input if this ever happened to them

Have I bricked my Wizard?

Hi folks,
I was attempting to flash Mr Clean's ROM onto my G4 Wizard the other day. All seemed to be fine, went to 100%, rebooted the phone, then booted up and started installing the cabs as it does on 1st boot.
Then the power just went off and I Cant boot it back up. I tried connecting the AC adaptor, nothing. SO I bought 4 AA batteries and put into my travel adaptor (takes 4 batteries and can charge the wizard) - after a few hours I got orange light on my wizard, but still wont charge/boot.
Any ideas please? Would a new battery let me re-flash it? Cos my friend has same fone, could I use his battery to save mine? If so what should I flash it with to be safe?
Cheers!!
Looks like the same I did, try to flash MrClean to a G4, and with that replacing the IPL/SPL... you got yourself a nice brick there.

oops!! thing is, i had mr clean on for quite a while before and it worked fine. not sure why it would suddenyl stop liking it? i guess its to do with the rom i put on after mr clean's??
so there is nothing i can do with this? no way of anyone repairing it, even at a cost (small!!)?
Why don't you contact the service provider & if it is under warranty they should repair/ replace it.
Just make sure you don't tell them the real reason why it turned into a brick!!!!

[Q] any solution for this brick?

my captivate cannot turn on at all
NO galaxy s, NO atnt screen, NOTHING
dead like without battery (but i am sure the battery is half full cos i tried it on another phone)
computer won't recognize it when usb plugged
cannot charge at all, no charging screen
SO NO download mode, NO recovery mode
tried all those remove sim, remove sd, remove battery, turn on odin first, connect to pc, having 3 buttons (actually all possible combinations) press, power button release, everything i could found on forum...
the only thing i didn't try yet is the 301k resistor
have a fd making that for me, will try that soon
but i doubt it will work since the situation looks very bad
so my question is...
has anyone with the EXACT symptoms, able to unbrick at last?
if u r those who able to unbrick becos ur captivate was still able to turn on
please don't reply, i really really appreciate ur help
but sorry urs wasn't really "brick"
and those solutions aren't what i looking for
if you want to know what i did...
all i did was trying to flash to Cognition v2.3b6 from a stock 2.1 following the wiki
i watched it formatting, copying files, ... , and then it try to reboot
but instead of successful reboot it stay dead forever
great...
tested even with the 301k resistor now
no luck
Yeah sorry man. Looks like you got a bad phone. Time to call att
i wish, but i didn't buy it from atnt
no receipt no shxx
and i am in canada
You know you still have the manufacturer's warranty. One year. Call Samsung and they will refurb it for ya. I got mine in Canada too. No receipt required as long as you have the original barcode on your box.

You're not holding onto the resistor with bare hands right?
I just get the same problem.
waiting for the solution too.
Have you tried a new battery?
This is my captivate. There are many like it but this one is mine.
your Phone most likely not bricked.
I Actually had this same problem. I really thought my phone was bricked. I would pull the battery and put it back in and nothing but a black screen. I ended up having to go into download mode from another computer. If you do this install drivers first and try to go into download by pushing both volume up and down at the same time then plug in usb cable to computer with odin opened up.

the 301k resistor tested on my gf "still" working captivate
it works
I end up took it to some cell repair shop to fix it
they said they had to replace a chip inside
and it cost me cad$150
anyway now it's fixed
but i think i am going to sell it since i don't have much faith in it anymore
i can't keep a phone that i can't flash it just becos it might never boot again
to those who have the same problem
GOOD LUCK
Doesn't it really work with the JIG?
If it doesn't work, I would not try.
If I just give the phone back to the ATT to fix it or change another one, how much should I pay?
thanks.

Finally, i got hard bricked...

Hello. Sorry for my english.
I've been living on the edge, like many of us LOL, and i finally got hard bricked. No battery charge, logo, download mode. Nothing. Just a black screen.
I was using ICS stunner 1.4.26 and decided to flash Catastrophic Meltdown 9 (CM9 for friends). The problems was that my battery died when it was installing the kernel, or the boot, i dont know.
So, i have been reading a lot those days but nothing seems to work. I have ordered a Jig but i think is not going to work. Yesterday i used windows, and something was detected when i plugged in the usb, but Odin not.Today it does not work, and windows doesnt play any sound. Any idea? A Jag?
I should say this is the best mobile phone i have ever touched. I would be eternal grateful with all of you if we could fix this mess. I was aware that there were risks. Im aware now maybe i cant fixit and im not gonna blame anyone because it was my responsability, but any help would be appreciated. Thanks.
Same thing happened to me, nothing worked (tried the JIG). I had to send it in for repair, but they didn't see that it was my fault (still had warranty).

From my experience the only way u can get ur phone back in service is go to ssc and make some reasonable reason why ur phone is dead, so u can still claim for warranty and I am sure they will replace ur engine/mobo like my friends did a month ago.

It has nothing to do with your battery dying and everything with trying to flash CM9 directly from super-dangerous LP5 or LP6 leak ICS kernel.
No jig or JTag will revive your phone now.
However, if your Note refuses to go into download or recovery mode, you are in luck - if you have a warranty, that is. Just take your phone to the service center and tell them that it died when updating via Kies. There is no way for them to tell what had really happened and they will have to replace your motherboard free of charge.
Sadly, jig didnt solve the problem. Battery isnt hot when plugged in, is my motherboard fried by flashing the note?
Could a jtag solve the problem?
Try to take it back in for warranty before attempting a JTAG and voiding the warranty (that they can tell)

Yeah, that's a classic superbrick, need replacement mobo. Sorry dude. As mentioned just say you were updating ics ota or through kies.

I got the same problem few days back..I went to service center and said that i got an ota update and after downloading had completed,it started rebooting and there i got some errors and finally my phone is dead
They were unable to find the exact reason why it got bricked as it was unable to enter download or recovery mode
So they replaced the motherboard under warrenty
Better this it once
All the best :good:
I dont think that warranty thing is gonna work, because i have lost some inside cover screws... yeah, thats a long story trying to fix it. If i borrow a motherboard... could i recover my data? because thats all i want at the moment. Or, is there any website where i can buy it? Otherwise, im going to try it with the warranty...

If you change your motherboard,you will lose all your data
I just came back from the service center and they are covering it under warranty . Similar symptoms and they are going to replace the whole board. Just take it to the service center and say "Yo man your **** died on it own" :fingers-crossed:

[Q] LG Optimus Black Bricked

Hello All,
My OB is bricked, i was flashing it with smartflash tool and installing official lg optimus gb image, but suddenly it was bricked. Now it is not starting, not even in download mode, no signal of power.
Any ideas?
It caused bcoz of loose cable connection.
While flashing any ROM, cable should have intact connectivity..

Probably a hard brick, bring it to a lg service center. Tell them you tried to update your phone and all of a sudden the update stopped and now it doesnt react anymore.

ok, but is there any other way?
In case of hard rest, as N00BY0815 said, only way is to take the phone to LG service center, but you have to take precaution regarding:
Take out the memory card and keep at ur home, in case you rooted the phone, otherwise they will know that U rooted the phone and reject the warranty.
i dont think rooting is against warranty everywhere does your pc recognises it when you plug it in while holding p
volume+ ?

He already said, it doesnt even turn on in download mode, so there is no chance to revive it. LG will not know, if it was rooted or not, since noone can turn it on and check it. So just do what i told you above and everything should be good again

This is software error not hardware error. They can't charge you buying new free software.
If its hardware error, in this case, then the problem is not caused by the root and they can't reject warrenty (at least in Europe, I'm pretty sure in most places they'll get away with it.)
EDIT
@Nooby
If they can't access it through new bootloader they have to use JTAG equipement and then you can read and write to flash memory.

I have not much knowledge like xonar and N00BY0815,
Maybe they used JTAG or something ..bcoz at first they try to know whether it is rooted and non-rooted to get reject the phone here.
At that time, I contacted the most senior developers here in XDA, they also suggested that there is nothing to do if the phone is not turning on, & take it to service center...(the case is of LG P500)
That's strange. When I hard bricked mine, they kept my phone 3 weeks to finally say that it was the motherboard which died (I flashed a P990 rom by mistakes, it was for a friend but I forgot it in my sdcard).

11 days ago i installed cm10 nightly 11-14-12 after using the rom about 4 days, suddenly while charging my phone turn off and didn't turn on again. It can't enter sw upgrade. When i send it to the lg service center they said that it was a motherboard problem and need to replace it. It cause P9,000 (about $214). What the F**K! The brand new Optimus black here cause around P13,000 ($309). My warranty is already expired so i decided not to replace the motherboard and wait for the release of nexus 4 here in my country.
That time i'm using blackberry charger 5v output. Do you guys think that the hardbricked has also something related to the charger?
