SM-950F Hard bricked, JTAG? - Samsung Galaxy S8 Questions and Answers

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?

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.

[Q] Tattoo Bricked

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)

need help wit sgt-p1010, please!!!!!!!

hey guys is will need some help with this device im not kind of a noobie on this kind of things bcs i been working with several phones, like the veteran xperia10, galaxy ace, motoroi2, etc etc. but never with a tablet
here is what it happens a friend ask me if i can upgrade his sgt-p1010 to a newer version, honeycomb or maybe ics, i´ve read a lot of posts regarding this on how to upgrade it trough odin everything was fine until the reboot of the device, bcs by my mistake i flash a rom of the 7.7" tab and this one is a 7" only now the tab is not turning on, odin is not recognizing it, either samsung kies or the pc. buttons are not responding it wont charge and cant enter to download mode.
I REALLY NEED HELP FROM U GUYS, HOPE U CAN HELP ME
ps. srry for my english :laugh:
This kind of thing can result in the inability to boot which can only be repaired by the use of specific hardware, i.e. this could be a "hard brick". Then again, maybe it can be restored to working order by flashing it again (a "soft brick"). So the very first thing you need to know is, can it get to download mode?
Turn it off, if it's switched on, and charge it for a couple of hours,say four hours. Use the original charger connected to mains. It doesn't matter if it shows anything, or nothing on the screen, let it charge. This is to make sure flashing it won't fail because it doesn't hold a charge.
Now connect it to the PC with the original USB cable. Then after making sure it's switched off, switch it on by pressing the On/Off button, while simultaneously the Volume UP switch. Press them both at the same time, and keep them pressed! If you're lucky you'll get the yellow graphic with the download text. A phone symbol, an !, and a PC symbol is fine too. Even if it doesn't show anything, you may be in download mode, so install the right drivers, and hopefully Odin or Heimdall will recognise is, and will allow you to flash the right ROM.
well i already let it charge for all night long and nothing happens after i perfomed the flashing the screen was totally in black but it doesnt shoes anything i mean the tab was turned on, then apparently batterie dies and after that is not charging. already tried with the heimdall thing but it says that device is not connected.
I think that this is going to be a HARD BRICK
so do u thhink there is another way to solve it?????
or it will be necessary the JTAG stuff???? bcs i dont want to try that it seems that is very difficult to me bcs i dont know nothing about hardware jejejeje
You have installed the Heimdall driver? It's called zadig.exe. Then you have to go to download mode and connect the Tab to the PC with the USB cable. Then Heimdall hopefully will detect the Tab.
If there's no way software will revive the Tab, it's hard bricked and will need hardware to get it working again. There's this guy mobiletechvideos.com who will repair any kind of brick. Basically he uses the JTAG on the board of the Tab and a special box to flash the right ROM to the Tab, even when it's dead. Some here have tried the service, and they say he's quite reliable. Another way is to modify your Tab with Adam Outler's Unbrickable Mod. It's brilliant, you can't soft brick your Tab after that, but it involves soldering very small components on the board of the Tab. The mobiletechvideos guy can do it for you I believe.
Well, I guess you just got a hardbrick .
The only way to fix this problem is go to SAMSUNG SERVICE CENTER.

[Q] LG D802 PWR button not working after recovery from HS-USB QDLoader 9008 mode

Hi all,
after some time in trials to recover the dead LG G2 D802 it has become true. With help of another member of the xda forum I have succeeded to recover the phone. ... But strange things appear after that. The phone does not want to start from the Power-off/on button. Also I can not enter recovery by pressing VolDown+Power. The only thing I can do is to put in DownloadMode. I mean it react to pressing VolUp and plugging it to the PC. Then I can flash it with LG_Flash_Tool_2014 and after that the phone starts.
Then I am doing all the initial steps of setting the Android and it is working. I am testing the functionality of VolUp and VolDOwn buttons and seems that they are working fine.
If I am not turning the phone OFF all is fine. If I decide to turn it off (by PowerOff) it works a bit strange - when I pres it long it does not give me the options PowerOff, Reboot etc. , but just turn-off the phone.
Then no way to turn it ON again. The only way is to put it in download mode and to flash it again.
If it is powered-off and I put it on the charger it is charging normally and when reach 100% it show the picture on the screen. And that it is.
But no way to power it ON by button.
I hope someone could help with this symptoms.
How was your phone got bricked to go into only qdloader 9008? What were you flasng or what rom were you using?
The phone was bricked during flashing of update. Then I found the tread about No Download No Recovery etc. Via the test point I moved it to qdloader 9008. Then with some help and the program similar (or same I can't exactly remember) like BoardDiag3.99c we managed to upload the main parts from the OS and the soft in case to wake up the phone. Then the phone was able to go in Download Mode and using LG Flash Tool 2014 I have flashed the official FW for it (downloaded on my PC - D80220C_00.kdz). The phone is D802 (aftabalam8c2 asked me to dismount the board and to look on it to verify the model). On the box of the phone is written that it is 16G version 6WT. I checked and seems to be Taiwan version with open soft (no operator locked). Now the phone is working very good except the problem that the button Power OFF is not working. If I press it long it is not coming the menu "Power Off - Resrat - etc." but just the phone is turning off. Then the only thing is is able to do is to go on Download again. No Recovery, No simple turn ON. Then in download I can flash it again and then the soft turn it ON after the flash is done.
I made few trials with different FW for Taiwan/HonkKong (D80220C_00.kdz - 1,62 GB (1*743*288*886 bytes) and Hong Kong D80220C_00.kdz - 1,60 GB (1*723*173*312 bytes)) but the result is always the same.
Also I disconnected and checked the buttons. They are working fine - measured wirh Ohm meter on the connector.
Also I made few trials with another equipment - Octopus Box. It is possible not to flash the whole phone. In Octopus there is an option to read the NVRAM in DOwnload Mode. If I do it the the Octopus Soft after that turns / restarts the phone and it start in normal mode.
Unfortunately this friend does not remember what FW he was trying to flash when he got bricked. One time he told me he was trying to update the FW (OTA) after that he mentioned he was trying to flash another ROM. It was mess done 2,5 months ago, but just last week I was able to pay some attention to his phone.
I assumed it was OTA and downloaded the official FW according to the model, region and the memory.
The only difference was that during the qdloader 9008 mode the phone was flashed with files for (d802 32GB mbn) 32G version. Not 16G.
Regards
Maybe something got fried on the motherboard? Anyway here are the service manuals for G2 (not all model). I hope you could track what goes wrong from the power button with the help of the service manual. https://mega.co.nz/#F!HhhQiSqA!ESK4rT7LJB3MJCRJOU2GhQ
Thank you so much. I see there is a good diagram about the power and the TPs I need to check. Next days when I have a little free time will try to read and check according to the manual. I hope it could be repaired ... but despite my hope my logic whispers me that probably your suggestion is right - something got fried on the board.
If I find something which is reasonable will inform here.
Have a nice day

Bricked Huawei Nova, please help

Hi everyone
I tried to updade my huawei nova CAN-L11C530B130 to CAN-L11C432B340
I think the copy/paste of the UPDATE.APP ****ed up beacause the transfer time was very short...Anyway the phone accepted the update but turned off after that.
Now I can't boot, no recovery, no download mode, not even a charging led light.
Please tell me there is a way besides RMA
Thank you very much :good:
Well, either there is no charge (try keeping it on charger for a few hours) or it is totally bricked based on what you said. If it is completely unresponsive there is really nothing you can do.
Boot loader doesnt start as well?
Thanks for your help
I tried an all night charching but It did not help, no boot loader either.
What about the version I had : CAN-L11C530, I don't find any results about it on the internet, strange right ?
When I plug the phone to my computer I get "Qualcomm HS-USB QDLoader 9008 (COM3)"
You could try contacting Huawei support, their is a qualcomm flash tool. You need the tool and the rom to use it. I know it worked on the Nexus 5, but have seen nothing like it for us. I would try going to a shop and asking, but I do not know how viable that is for you.
Thank you wangdaning, it's very kind of you
I'm gonna leave the phone to the carrier who will send it to huawei.
I'm just surprised how easy it was to brick, I have a honor 8 and a mate 8 and it never happened.
I wonder if it comes down to it being a defective device. I have run circles of flashing on mine and it does not brick. I am running Lineage and even the build is not for my device. I have manually flashed partitions, wiped and reflashed partitions (in fastboot). I have made it unusable at times, but never bricked. It works fine now. Seems it might just be an unlucky bad unit you got. Hopefully you had all your stuff backed up and hopefully you get a unit that works well next time.

[Help pls] Note 3, not responding: Bricked? Installing Lineage OS

I just bought a BNIB Note 3.
Samsung Note 3: SM-N900W8
Symptoms: Won't turn on, no lights, no load screen, no recovery mode, no download mode.
When I hook the phone up to the PC via USB it does vibrate and sounds the connection ringtone
What I was doing when this happened:
I had just recently rooted using "KINGRoot" - checked root and it was successful
I installed "TWRP" and booted into recovery mode and it was a success as well(I didn't actually run here yet)
***I installed and opened "Flashfire" to Flash the LINEAGE OS to my Rom buuut I didn't actually select the Lineage pack and I accidently pressed FLash(insert expletive here) *****
So Flashfire went through it's loading and when it was done it shut off and then the symptoms started.
It's a Note3 from Bell with all of their bloatware on it and I wanted to clean it all off and run a clean/efficient Note 3 cell with Rogers. I'm not looking to keep any of the data currently on the phone as there isn't anything currently on it. I just want to be able to install Lineage and use my Note.
I've searched for 30 hours pretty solid so far and unfortunately I haven't come across a clear solution. Can anyone give me a diagnosis and a tutorial or a link to a fix.
I'm open to loading from MicroSD, USB Jig, Samsung Kies....anymore information you require from me as away and I'll get back ASAP

Battery - I did the "spin" test on the battery and it doesn't show any physical characteristics of an overheated(bulged) battery. I'm going to test fit my battery into another note3 and I'll respond asap.

I tried the battery in another Note3 and my battery is 52% charged and had no issues booting the tester phone.
I have the phone being tested for any Hardware issues right now.
If it's not a hardware issue will I be able to force a Rom(whether OEM Firmware or other) to install via MicroSD or USB jig?
When the phone is connected to a Windows machine, does a new device appear in device manager?
Have you tried to force it into download mode with a USB jig?
For flashing ROMs to the sm-n900w8, the simplest method is to flash TWRP, boot to TWRP, wipe everything, and flash the desired ROM.
If nothing works, you could take it to a cell repair shop and hopefully have it repaired with a jtag cable or a similar method.

No, the PC doesn't see the phone.
The USB jig or MicroSD force is something I'm researching to try next(feel free to provide any good links to set up a jig(I've done this with Ubuntu on my laptop but this has a more intimidating feel to it)). The Tech at the shop I took it to test the hardware says "the motherboard" is broken and he'll fix it for $60.
For future considerations I'll learn to use TWRP flashing ROMs.
If the shop is offering to fix it for $60, they may be just force-flashing the firmware with something like an Octopusbox.
The USB jig may force the phone into download. If it doesn't, I don't think you'll have a choice but to pay to have it flashed. Unfortunately, Samsung will not help as rooting would trip the knox counter.
USB jig ebay are the usual cheap source.
