Jtagging an android? - Android Q&A, Help & Troubleshooting

hi all my w8 got hard bricked during unlocking bootloading ...and my phone is pretty new ...my dad sent it to a repairman to get it fix...at 1st he said its a simple error and can be fixed in a day or 2..then after 2 days i asked my dad...my dad said the foreman overlooked the problem and is more serious that expected ...i got a little panic and did more research ..and according to my research my phone might need to be JTAG..i think ..the process looks pretty darn hard and have a RIFF box thing ...so i am just wondering ...will this process be known to all repairman?and how much will it cost?

big mistake flashed g3 ROM... help

i know im sure its bricked. i have flashed several g3s and g4s wizards but this time thinking that i knew what i was doing i flashed a g3 ROM to a g4 wizard.
is there any way to bring it back from the death?
i feel really stupid and sorry because its not my phone.
no ligths the power botton does not work, can't get it into bootloader mode, removeing the bateery does not help....
what can i do?
thanks for any advise.
She sounds bricked to me! If you cant get into bootloaders, then I do not think that there is any hope my friend...sorry!
how about jtags? i read somewhere that the jtags were found
here

No, Jtags is still not a solution. There is nothing can do for a bricked Wizard.
ok thanks guys. i will be more carefull next time becuase beleive me i will be flashing more htc devices soon

Cingular 8125 Wizard T-Mobile
My Phone wont start at all too.
G4 Cingular 8125 Wizard with T-mobile.
1 thing is that I hve tried every possible tactic from the book before writing this read every site on google related to unbricking and trying to learn everything about replacements. everything points to hopless options.
If IPhone can unbrick itself i'm sure we can get this working Duh !
However everytime I remove and insert rapidly the battrey, i can see the screen flashing and the red light blicks along with it.
I cant seem to get it stabalized to get into the boot menu...
I'm willing to donate the phone to find jtag however i'd like to learn it myself any tips on how to find the jtag points ?
Question 2
When you say Bricked, I know that the only option left is to replace the motherboard, however what i'd like to know is, Can some1 please explain wht does it exactly mean when people say Bricked ?, which part of the board is not working so that I can get the Chips replaced. Can we take this as an option, yes ?

You can bring a bricked G4 back to life..sort of. Go to eBay and find a working Wizard with broken screen or cracked up case or something so it's cheap. Take the motherboard out of that one and replace the one in your phone and you're back in business! I did it with my last bricked G4 and got a bonus when I discovered the used phone I bought was a G3 (practically un-brickable!..until I broke the LCD!)

[Q] Emegency Mode Help

I am trying to put my Optimus S into emergency mode by following these instructions here: http://cheapcellunlockedphones.com/how-to-fix-a-bricked-lg-optimus-s/
I can not get it into e-mode for nothing. All I get is a black screen. Is there something I am missing?
Nevermind, I got it.
hm. well heres a try
it appears i cannot post to where this is most related...bricked p500h's optimus ones. phone number 3. koodo shall hate me but i will lie again and just say no turn on if noone has a solution. everytime its the update-openoptimus as the culprit, the flash after as per instructions with baseband(force close always occurs and thats the next step) fails and phone goes dead. no life. bricked. whats rather saddening is all the hundreds of posts i read here about people calling their phones bricked when they are in fastboot or emergency mode. hell life would be nice...little note to people. fastboot or emergency mode is NOT a bricked phone. phone going dead during a kdz flash and fail with NO SIGN OF LIFE afterwards is a bricked phone. im going to cry if i see someone else say. i haz yellow screen. ARRGH I BRICKED MY PHONE!!~! HAAALP OH YE WIZARDS OF XDA!!!
now..is there some trick to give this guy power aside from a charged battery and plug via ac or usb...some hidden little nub in this phone to hella reset the freakin thing? im not confident koodo gonna send another. although i will say i dont want a lg ill pay for an upgrade above n beyond. i just would prefer to make this work and say to hell with ciaoux (think thats how the young fella spells it) pretty rom...it worked the first time and thats why i want it its nice i liked it then phone bricked somehow. gone through two more tryin to get there. there has to be a way to give these phones some power tho...has to be! pls xda gurus: this is my first post and ive waited awhile for it. how to save p500h no boot no post.
cheers,.
proud champion of actual phone bricking.

No. Just JTAG. Forget it, it costs more than a PCB change or even more than a brand new phone.
lol ill try my luck, 3rd replacement(if i was honest with them none of em woulda been outright replaced, but hey i was stupid enough to brick it 3 times, not gonna be so stupid to tell the truth what i did!) tomorrow am i call and say ***k lg! gimme a nexus s! 16gb internal. really ive fought gettin the one rom with 4gb sd-ext for internal memory, non issue if i persuade them with my charm. this is what i shall do. next up...lookup what jtagging is. ive meant to. guess now i will. thinkin without a thought its jtag=tagged for garbage. yanno when they take them in and theres no power. they have no real proof, not the provider i doubt. only on amce lg gets it they know whats was done..if that. fill me in if im wrong. im quite good at gettin **** for free from telus/shaw/any of them like outfits.
JTAG is a device that will flash the dead phone with a working firmware. You need to dismantle the phone and connect the JTAG to a connector on PCB. Yeah, Google it, but as said, expensive and totally not worth it unless you are doing the stuff for living.
totally not worth it..as in how much can these devices be. and how much or where would they maybe be found. i get **** cheaper then most ppl in most cases if the right places are sought out....imma server guy to be honest but lately ive had a pile of this phone stuff start piling up. ppl dont wanna pay much but somethin can be made for sure so maybe, thanks very much for the info i be keepin my ears to the ground! my buddy is tryin to figure the formulas used for imei > puk and imei > unlock. thatd be some handy info to have too. i got this one real nice arc.....nice. boneheads tried random net unlock codes like 200 times before i seen it. shoulda asked about that before i shelled out $5 for a code i had in 2 hrs. lol guess this isnt the place for this discussion tho....
koodos sendin another. easy enough. now. wtf does this rom upgrade to ciaoux's update-openoptimus keep pooching my phones for though. 3 tries.. 3 bricks, never on the actual rom upgrade...but afterwards always force close so i run fix permissions in recovery, followed by the v20g_00 baseband upgrade........this is where it fails everytime. i should note, in the past the lge virtual modem has been present but disabled as required, but not lately. its now always lge android usb modem....i dont think i disabled that guy.....maybe the problem? really leary about running any kdz or lpdm updater now for sure. to call in a 4th time in two weeks with a dead phone my provider is gonna sorta maybe start askin questions......im pretty sure. lol goddam i needa large capacity phone, i haz a 20tb server but only a 512mb capaacity droid phone. messed. ****.

[Q] Bricked Note I171

hi i followed some tutorial linking to a liquid something ics rom for this rom supposedly it was for my att note i717 so after doing all the steps, when i reached down to the comment sections i saw almost 10 comments that that rom was bricking phones, to my infinte good luck, i read all those comments AFTER i had done all steps and rebooted into the death of the phone
cant enter download mode, cant enter recovery mode
if i plug the phone into the pc it says qualcomm cdma technologies mms, and windows just keeps playing the sound when u plug in a usb and un plug it,
ODIN doesnt detects it and on adb devices it is not shown
Hard brick ? any thoughts on this anyone?
Hard brick. Sorry dude.
Sent from my SAMSUNG-SGH-I717 using xda premium

How to know if the MoBo is bricked

Hi!
Sorry for asking again - i had another thread about this subject before thinking this solution to my problem, I think the situation and the question is different, so that0s why I thought, opening a new thread was correct
What happened is that I was enjoying my SGSII with CM 10 and one day it just shut down
I only could enter download mode: When flashing with Odin, Odin would hung and the flashing process never would start.
Finally I tried to flash official 4.0.4 with the repartition option checked.
No download mode no more either....
Needless to say, I got a brick.
Now: Samsung refuses to repair it with the warranty and some online shop says they can repair just the memory module and not all the motherboard: I don't know if the motherboard was broken either.....
The thing is that I wish I knew if the MoBo was the problem before sending the device over to the online shop and getting it back not repaired again... having to pay for the delivery... perhaps for samsung it's easier to just replace all the inside instead of only one compound.... I don't know that....
How can I know if the problem is not the whole motherboard?
Thanks

I had the same problem not caused by cm but just trying to ged rid of jellybean, no boot, no download, no recovery and not charging anymore
i tought i was screwed by odin because this caused the problem ( also ticked repartition ) brought it to a shop that actually repairs damaged screens and after a couple of days got my phone back with still everything on there wat was on my phone before i bricked it.
Had to pay € 45,- so to me next to nothing compared to bying a new phone.
Well, that's a relieve... I mean, if the Motherboard were broken, I wouldn't even get to download mode... it clearly looked like the fash memory failed.... I hope this guys are right and I can get my phone back..
I need to say Samsungś service sucks!!!! Despite of not being covered by warranty, they had my phone, and i quote "LOST" for almost two months....
I'll update as I get the phone repaired....
Thats why it diddent even cross my mind tpo bring it to a samsung service center, it probally takes a lot longer to get the job done and they would for sure replace the mobo and then say it was broken because i flashed it with a custom firmware, like that wil break the device, morons
So to make sure it was done fast and the proper way i took it to flexiphone and sved my selfe the trouble of getting a lot of bull**** an probally a
high amount of money to pay (because of a warranty void) for a repair that never needed to be done in the first place.
Hope your device has the same problem cause i was depressed missing my righthand, but went home with a smile from ear to ear.
OK, got the phone back, took it to a shop and they say it's not responding to JTAG.....
They will try something else, but it does not look well....
if it's not jtagable then mobo replacement is your only chance to see the little guy booting again.

Ok, I've got a bricked MoBo....
How much would it be to get a new one? I guess it won't be less than 200 euro.... or perhaps new phone directly...
I guess It's goodbye..... farewell, SGSII.... :crying:
Mobo is about 150 - 200.

Orange were selling S2 for about 240 €(or whatever equates to £200) 3 months ago.
Id sell your phone on ebay as you should get at least £100 clear, then that means you could get a brand new phone with warranty for £100 difference, or maybe a good bit less.
Nexus 4 it is!!!

Unsure what to do next with LG E970, perm bricked?

Pardon the pun but I have hit a brick wall with my LG e970. Last night I followed this guide to root and unlock the boot loader and everything appered to go fine. Today I recieved my code to do a sim unlock and, this is where everything sarted to go wrong. After entering the code the phone tried to do an automatic reboot and hung on the LG logo screen. After doing some research and getting the phone into download mode I tried to unbrick it using this guide. After I finished flashing it I tried to reboot and to my dismay nothing happened, I mean nothing. My phone no longer even turns on and when I try to boot into download mode I get a QHSUSB download prompt on my pc. Is my phone toast? Is there any last resort actions I can take? Can anyone tell me what exactly happened?
Thanks in advance for any information.

following your links, your demise was the second guide you used. That guide is for the INTERNATIONAL VERSION of the optimus G, you have the AT&T variant, thus ending up with a nice brick(phones are completely different). Sorry to say but as far as i know there has been no progress on the QHSUSB mode front ( http://forum.xda-developers.com/showthread.php?t=2458139&page=2). Looks like JTAG is your only option right now, might as well google about it.
wow, I'm not quite sure how I feel right now. That's what I get for becoming frustrated and impatient. Should have gone to bed and dealt with it in the morning. What exactly is QHSUSB? Is there any chance this is something at&t would deal with? I would rather pay a repair few then have to buy a new phone.
Thanks

Don't really know much about QHSUSB, just enough to know that when you get it you are hard bricked. Wouldn't know if at&t would deal with it(if it is under warranty you might as well give it a shot), otherwise go for jtag.

AT&T may try to charge full price if they decide warranty is void, or that could be just a myth. LG has a one year manufacturer warranty, I don't know their policy for covered repairs.
