Hi all, let me start by saying i apologise if this is the wrong section!!
I am running (sort of...) an lg g4 h815, rooted, but at the moment im stuck, so hoping to find info here
The phone at the moment is hard bricked and doesnt respond at all with/without battery, plugged into pc. No light, no download, and no recovery mode - litterally a brick..... i have opened up phone thinking that if i can get it to power up at all, i might be able to recover data or possibly even flash new files over to recover.
Pc dosent see it, not listed as adb device
What im asking really is, is there any way to just power up the internals so as its recognised my pc?? Even if that means connecting components on logicboard?
Any advice tutorial would be greatly appreciated as in its current state have not alot to loose
Xda has always come up trumps in the past
Thank you all on advance!

Hello,
I tried to update the radio and the SPL version on my Tattoo. Everything went fine until I had to reboot my phone. It shut down alright, but it never powered on again.
These are the following problems I am having with my Tattoo at the moment:
Cannot power on phone.
Cannot boot into recovery mode.
Cannot boot into FastBoot.
When I connect it to my computer via USB, nothing happens.
The only thing that it's responding to is when I connect my it to my charger.
Does anyone have a solution or is my phone dead forever?
Thanks ahead!
bump? anyone?
Send it back to HTC. If anyone can do anything about it they can. There's nothing else you can do. Sorry
boo.. that sucks..
Well, thanks anyway
Ehm, I don't want to post a New Thread so I'm gonna ask here:
Does anyone have the pinout for the Tattoo?
Take a look at this. I guess they fix such things (but you never know if they just are after your money. http://www.ort-jtag.com/index.php
Yeah I saw that already. Also, there is a file name Tattoo Jtag on their website in the Support section. However, to access that section you have to enter your products serial number (which is I'm guessing the phone's serial number). I have tried several serial numbers (including mine) and all of them were 'invalid' so I never checked the files out.
Also, they only have one thing in the shop which is a kit and it costs $330 so no thanks
I have a similar problem, I would like to share my knowledge although I must be completely out of way.
My experience is based on the BeagleBoard and Angstrom so I really don't know the HTC HW and Android at all...
- The device boots from an xloader that instructs the device how to proceed with the boot
- the bootloader takes place (great u-boot in the beagleboard ?? in the HTC phone) the bootloader allows for ROM or kernel+rootfs flashing and much more
- now the kernel is loaded.....
User mode applications do not allow to have access to the memory area where xloader and u-boot lie so they should be safe all the time to allow for device reflashing.
So we should have access to the device via bootloader anytime if we knew how... maybe somebody can help us further.

Same here...Exact same issue...No Recovery mode...No USB Connectivity, Screen turns on but is blank, alhough I did see Tattoo popping up initially but not any more...All I can see is the LCD back light turns on...Battery does charge...Also when I try to enter Recovery mode screen keeps blinking as if it is trying to restart again and again...Someone help
similar problem here, but i get absolutely no response from the phone, it doesn't even recognize the charger. do i just throw it away and buy a decent one or is there a solution?
Sparky the only way for now to fix that click is to bring it to some service point that have that ort jtag, because only way to fix that is to writte new boot sector on phone . Im sure that i know at least 2 services that have ort jtag in Novi Sad . Look for marvel *Miroslav in Ns, or send me private message
same thing happened to me
just this morning, and in desperation I tried hard to remove the batt cover (prob pressed some of buttons, I felt a jerk and ho it was back in amon ra`s recovery, nect time I just removed the battery waited for 30 secs, then press off&home and hold it till recovery came back) but for good half hour NO REACTIONS , ABSOLUTE BRICK, nothing when I put the usb in PC or in socket, dead screen, no sounds and no reaction to ANY combination of keypress. I guess you could call me lucky (in last few days I flashed at least 3 versions of froyo roms, this afternoon I bought =8GB class4 Kingston, formated it in PC FAT32 default size, copied EVE. from my 2gig rom then just turned it down (yes I am brave) and put the 8gig in tattoo, it works like a charm (finger crossed it will continue)
So is there an available Jtag for the Tattoo yet?
I'm in the same situation. No recovery no fast boot, Damm!
I`ve update psfreedom with psgroove_hermes_v4 zip file then my tattoo reboot and now I only get the Tatto title screen but nothing happends.
Somebody have clue to give back life my phone.
Thanks!
if you can get to the title screen, that means you can connect it to your pc via USB and recover from a backup (I hope you made one)
Hello, I connect my tattoo to my pc, but usb connection is not available yet.

You have to enter in fastboot.
Hold volume down and turn on phone.
Cheers
Sorry but as i said before, I can't access to recovery menu neither fast boot menu.
A few weeks ago my girlfriend rebooted my Neuxs 7 but it somehow got in a bootloop. I tried to fix this but i managed to shred the bootloader i guess because now it won't turn on at all.
I've tried to boot it into fastboot, but that won't work, so i'm pretty sure that the bootloader is broken.
When i plug it in to my computer and hold in the powerbutton it shows up as a apx device, which i guess is a good thing in this situation (meaning i havn't completely broken the device).
I'm not very skilled with these kind of situations and really need help from you guys.
I've read about apx drivers and if i understand the situation correctly i could somehow install a new bootloader this way?
Could anyone help me step by step restoring my precious Nexus?
I could send it to service, but i don't think i have any warrenty left on it since i bought it almost 2 years ago. I also suspect it would cost me a lot of money if i send it to service.
Please give me happy answers
Pretty sure you needed to make a backup of your device first to flash back with apx mode as this is device specific
Same problem here.
From what I read the only way to restore your N7 in APX mode is if you had a backup(again from apx mode).But now the device doesn't have(or its broken somehow) a bootloader anymore so we can't do it.
If you still have warranty return it,if you don't buy a new motherboard(40-60$ on ebay depending on the storage) and change it your self.There is plenty of tutorials on the web how to do it.
Good luck.
I believe I have the same issue. Nothing on screen, does not come up on computer but shows as APX. Does back up have to be from our device or can a backup be made by someone and we restore from that copy?
To the best of my understanding it is device specific so for those who want to be safe make a backup now as you can't use someone elses

Okay, well that sucks! Guess i'll have to order a new motherboard then.
Hey guys. I tried rooting my LG G4c but after rebootingen it seems that my phone is stuck in a loop, and i can't fix it.
What happens when i turn the phone on:
1. LG logo turn up
2. The following message appears:
[670] --------------------------------------
[670]
[670] Boot verification fail!!
[670] - cause : MISMATCH_SIG_LEN
[670]
[670] --------------------------------------
3. Phone reboots
Using the power button + volume down does NOT work anymore to start recovery mode (although starting the IMEI display still works).
I tried using LG UP to install the original firmware via USB but the device does not show up in the list (probably because the phone keeps rebooting itself). Some website also said to connect the phone with the pc, turn LG UP on, then put out the battery and put it back in to make it work, but that also didn't work.
Anyone know what i can try next? What method can i use to reinstall the firmware? And if it's not possible, does it cost much to repair and who should i ask?
Edit: It seems i can start "Factory data reset" but when this proces starts the phone restarts and continues the loop with the error message.
I also tried connecting the device with LG UP while the phone is stalled on the IMEI screen and the Factory data reset screen. This way the phone does note restart itself and it might appear in the device list of LG UP. But too bad it still didn't work.
I don't know if i'm reaching anyone who can help me, but even a answer from anyone saying that the problem is hard to deal with would already be very relieving I really can't find anything related to this problem on the internet and i'm noobish myself. I'm probably gonna visit a some phone shop down town in the next days because i really don't know what to do.

I had this problem too. I send it to LG and said the phone was unplugged during update process. They flashed it and I gave it to my mom. I have an S4 yet. Much better performance and rom support.
download mode

Can you get it into download mode?
Hey
So I was flashing android 7.0 to an S8 and it completely died, this is how completely:
- No screen/LED/vibration motor
- No safety/recovery/download mode (and don't ask about button combos, I've tried them all)
- No USB recognition from device manager (not even as exynos in other devices, just nothing)
- USB jig does nothing
- It is however recognised by wireless chargers (but I doubt that has any real significance)
At this point my question is would a JTAG even work on it? Or is my only hope a complete motherboard replacement?
S8 Hard bricked

Jtag dead phone to life and rewrite IMEI
I had the same thing, sent it to Fonefunshop in England, they said they could fix it, the didn't even open it as discovered by the guys who fixed it and is necessary to use jtag.
Fonefunshop said eMMC chip was bad, which is not true, but that led me to search for someone to replace the chip. I found A2Z cellular in Ottawa, Canada. They got the phone to boot up, but IMMEI was null( I did this trying to flash back to stock after TWRP screwed up). They rewrote original IMEI , now phone works like new. These guys are amazing.

Thank you all for the advice.
But I have now managed to unbrick and reflash the firmware. khawarjaved's advice turned out to be what fixed it in the end.
That was close, nearly lost £30

I have been through that situation man.... So always ready to help, ??
Hi pros
I'm in kind of a similar situation....I think I flashed MY 950U PIE with wrong BL
This phone is dead....Doesn't boot...no download mode....No recovery mode....
When connected to pc....device manager Recognises device as QUALCOMM HS USB 9008
Any way to brig it back to life...?
Your phone is connected in edl download mod. It will accept special files which will allow it to boot to download mode and let you flash stock firmware
The tool used for this is emmcdl.exe
It has to come with phone specific files
No idea where to get it. Ask people here, those who root phones. They know.
Hi everyone,
Sorry if there was an answer but after reading several thread haven t found one solved that would correspond to my question.
I will be looking to at least recover potential photos etc I may had no backed up yet back then.
I have an LG phone which suddenly start boot looping some times ago (Never did anything as installing costum version or such thing)
In my memory the same day or day before there was firmware upgrade. Phone ran out of battery while sleeping and then was stuck.
I did try a few things back then but did not solve and giving another try now.
Current situation as below
- Model H990DS
- Download mode do not stay on: Disappear then back to LG logo (No detection sound when connect to pc)
- Fastboot do stay on and I can hear the usual windows when connection external device (It does actually open huawei phone soft when connection the LG phone) but phone do not appear.
Is there anything i can try from there?
I read stuff about twrp or other things but not sure if it will help and would like to avoid doing something which may make it harder to solve the issue?
Thanks in advance for your help!
NB: Tried to check with LG but they do not support phone where I am apparetely
