So im trying to unbrick my 3t, its my 2nd device.. and i tried with MSM tool. i keep getting errors such as firehouse communiocation handshake failed, sahara communication etc. For some reason when i just hold vol up by itself it doesnt show up as qualcomm in device manager. i have to hold power as well. but i keep getting different errors
The correct way to enter Qualcomm restore is by making sure the phone is 100% turned off and wait some more. Then keep pressing volume up while connecting cable until device shows up as the Qualcomm restore device. If it doesn't work, choose an USB 2.0 port instead of 3.0 or the other way aroune if possible or try another USB-C cable. And if it still doesn't work, maybe the PCB or USB connector of phone is broken in hardware.

You can try pressing and holding down the power button for 40 seconds when phone is on, this should force shutdown your phone without entering quickboot powersave as I think you will get this firehousecheckrsp error if phone was shutdown normal from OxygenOS ROM.
After this, startup the Qualcomm tool on PC, hold volume up and connect USB-cable. Check Windows Device Manager that the Qualcomm device is there and that the driver is working without any exclamation mark on it.

Hello, happy greetings to you and I hope you are safe. I also keep getting firehousecheckrsp failed sahara communication etc even if my device is surely 100% off (as it has no indicator whatsoever even if connected to the power brick, no vibration, just plain black screen). Also did hold the power button for more than 40 secs just to be sure. Though a bit of good news I guess is that my device can be detected as Qualcomm 9008 in Ports & Com in Device Manager when I hold the volume up button for several seconds.
Btw, these are the tools I used but none of them worked.

PLEASE HELP ME!
I was trying to flash back to stock but odin3 just sits at factoryfs.rfs
Read a different thread which said that you should unplug and replug into a different USB port. Tried that however got an immediate black screen.
The phone doesnt show the battery symbol when plugged into a charger.
If i can get into download mode I think I can flash stock with Odin3 because I changed the programs privileges to admin and turned compatibility mode on with WinXP SP2
Essentially NOTHING comes up on the screen, regular boot up is out of the question and I cant even get into download or recovery mode. 100% dead regardless of what i do.
I've tried the 3 button download mode trick. I held Volume down / up / POWER before plugging in the USB and Battery....I've tried everything and nothing is getting this thing out of a complete brick.
I've also read that you can make a wire and solder pins 4 and 5 of the micro wire with a 301K ohm resistor in between to simulate the 3 button trick...But im skeptical it'll work at all. (Going to try it soon anyways).
My question is.. What else can I try to get this to Download mode??
PLEASE HELP.
anyone ? any information is appreciated.
I have the same problem just like you.
I am waiting for the solution too.
As I know there was no way now.
u might have to try doing the solderless trick..ill reserach and see what i find though
Give the JIG (301k resistor between pin 4+5) more credit!
Here's a parts list and solderless directors to make a jig:

there are other ways to get into download mode.
Have you tried just holding the up and down volume buttons and then plugging in, or the adb method (adb reboot download)?
I have the exact same problem. my phone came back for a second with portrait mode and usb connectivity. usb worked on my desktop computer, i freaked out and ran to my laptop (that had odin one click, and mod software loaded on it) and plugged it in. while plugging it in to my laptop i noticed a bright blue spark on the usb connector wich i already had plugged into my phone and immediatly lost usb connectivity and went back to being stuck in landscape mode.... i wonder if this has something to do with it?
i had a similar problem and really thought my phone was bricked. I ended up having to use another computer to enter download mode. i installed the drivers first from the odin thread and held the up and down volume keys and plugged in the cable and it came back to life. This was after 24 hours or so of trying every possible combination and getting nothing but a black screen using my original computer.
When I connected the i897 and computer, there was nothing happened. No charging shows. No every modes. the screen have no response.

so i gave the 301K resistor and it worked beautifully!
- Fired up to download mode
- Opened odin (as admin and with compatibility on WinXP SP2)
- Plugged it in
- Clicked start on Odin.
apparently the new Galaxy S's dont have a hardware 3 button reset to get into download mode.
I've tried to put a new ROM using Clockwork Recovery 6.0.1.2, during process it stuck for 4 hours and was turned off by power button.
After that tab don't react on power button, on pwr+vol up, pwr+vol down, pwr+ both vol buttons, nothing.
It even doesn't show battery icon when charging - screen is always black.
Any advices?
Thanks in advance.

1. Put on your computer headphones and turn the volume up.
2. Plug your tablet into your computer via USB.
3. Hold the power button & Vol - keys together (Volume - is the side that is closest to the power button)
4. Listen for the "USB device connected" or "USB device disconnected" sound on your PC
5. If you can hear that, something has gone bad within the bootloader and the display does not initialize properly. Edit: The ICS installation does indeed attempt to patch the bootloader
6. If there is no sound, then the tablet is stuck in limbo, so go ahead and do the battery drain procedure as described in the above post.
7. If, however, your computer detects a device connecting and makes the sound, you can most likely still enter Download mode. You will have to do it blindfolded though:
-open ODIN 1.85 and see if it shows a connected device. If your PC made a connected sound, then there will most likely be a yellow COM port in ODIN.
- Hold [Power] & [Volume Down] together for 15 seconds or longer whilst monitoring your Device Manager windows to see if you can get the tablet out of APX mode and have it appear as another type of Device. Then press Volume+ several times with 1.5 sec. intervals. With luck, this should get you into Download mode, and ODIN will shine yellow for you.
- While doing all of the above keep your headphones on and listen for connected or disconnected sounds from your PC.
- Make sure you have this firmware for the P7300 which contains a bootloader, which is essential: http://www.hotfile.com/dl/162686792/c693269/P7300ZSKK2_P7300ZZHKK2_TGY.zip.html
- Flash with "Bootloader update" checked in ODIN and see if device is resuscitated. If the tablet boots, it will be in Hong-Kongish, but just select a language you recognize from the dropdown, it has them all.
- It may be a good idea to also throw in a .pit file and check Repartiton
N.B. The firmware link that I have provided is for the Tab 8.9 3G P7300 only! Do not flash it on another version of the 8.9!
You will need to search for a firmware that contains a bootloader.bin.md5 file for your tablet model.
Again, all of this will only be possible if the device registers with your PC on connecting the USB cable.

Ok, I've disassembled the device, and removed a battery connector for a time.
Didn't help though.
When I'm connecting tab to PC and holding pwr+vol_down, I hear that connect-disconnect sound and there is a device called
NVIDIA USB Boot-recovery driver for Mobile devices blinking in Device Manager with those sounds.
Odin shows no yellow com, all are empty, so download mode is not available.
you are stuck in APX mode , First go to this link and follow the instructions : http://forum.xda-developers.com/showthread.php?t=1130574]
if you get this in nvflash :
Nvflash started
rcm version 0X4

this means your device is locked and the battery draining is that last thing that might work for you .
i still didn't try it, but i only disconnected the battery and connect it again but my device still dead for a month now .

unfortunately the sbk (secure boot key) for locked Samsung devices is unknown and i was hoping that someone will be able to provide it since it's now increasing problem for 8.9 and 10.1 tabs especially after ics update . actually this is well known mode(apx) with all Nvidia Tegra devices such as acer a100 tablet and asus transformer ee pad but developers there were able to find the sbk for these devices .
if you are covered by warranty and the battery drain method didn't solve the problem you should go to Samsung and good luck . i am not covered by warranty and the only solution i found after connecting Samsung here in Egypt is replacing the mainboard costing almost as a new device (even Samsung couldn't fix it) .

Sounds like they want to get your cash.
If things went to sh*t software-wise, they can be fixed the same way.
They could just UART into the board and restore the bootloader. I don't have to expertise to do it, but they should have it.

I had a broken bootloader and my display was dead the same way all of youse with bricked tabs describe.
It appears that in your case the bootloader is so badly messed up, that a fail-safe kicks in and sends the tab into APX mode directly.
Consider disassembling your device to disconnect the battery, press Power a few times with ti disconnected and keep it disconnected for a minute or so to force discharge of all capacitors, then reconnecting and attempting a reboot.
Disassembly is really easy - get a plastic knife and stick it under the display near the charging port and work your way around the whole unit. The entire display comes out of the back cover. Flip the display around and there you will notice where the battery connects to the main board, unplug the connector.
Have you tried?
And wut i must do after that?

Disassemble, disconnect battery, press power, short + and - (on device, not on battery lol)... After that connect battery and connect via usb ... the same. cant enter download menu.(

My tab has a blank screen and went through the steps you mentioned. ODIN has a yellow com port and when I try to flash the firmware+bootloader ODIN stops in "SetupConnection".. I tried to change port, cable, odon version to no avail. Any ideas? Thanks!
So, I let a friend of mine use my old M7 in order to repartition/format an sd card (using an OTG adapter). Came back with phone completely dead. I do suspect he ended up partitioning or formatting one of the system partitions in there (possibly the bootloader?) phone was rooted so...
Anyway, situation is as follows: Phone looks dead. Long pressing the power button does nothing, no vibration, no keys light up, no screen comes on.
BUT, when connecting it to the computer I get the usb connection sound on my Windows 10. If I long press the power button for ~10 seconds, i do get the usb disconnection sound, followed again by the usb connection sound. So "something" is alive in there. Also, power+vol down button does reboot the phone.
However there's no way to access recovery, bootloader, adb/fastboot, or even flash a RUU.
It isn't even charging when I plug it in, no red led.
Anything else I could try before giving up?
Thank you.

When you here that USB sound when connecting to your pc, go to the windows device manager and look for devices in the usb section. Is the phone showing as "QHSUSB_DLOAD" or simply "HTC Phone" ?

Yep sounds like your phone is in Qualcomm download mode. Usually this can happens for 2 reasons.
1- Hardware failure
2- Bad firmware flash
this thread can help: https://forum.xda-developers.com/showthread.php?t=2770684
Hard to tell since we don't know what your friend exactly did or what was used from that usb-otg drive.
A phone shop that can connect to your phone using jtag/riff could maybe fix it but doesn't worth the $$ asked for a 2013 phone, imo.

As far as he told me, he just used an app to try to format the otg drive, multiple times, and after a reboot phone died. He couldn't remember which app he used, but since phone was rooted, I can only guess he actually tried to format some system partition.

My friend has an S21 Ultra 5G with the Exynos SoC. There's an app that constantly crashes, Samsung Audio Remote, that he NEEDS to control the volume on his sound bar because he's handicapped and can not use a physical remote. After a total of 3 HOURS on the phone with Samsung support, the next step and alleged solution is to wipe the cache partition. But I can not get I to recovery. The procedure support told me to use, that I tried 3 times while they were on the phone, did not work. Now, I'm no tech god, but I have successfully flashed dozens of roms on several devices over the years, including 4 Samsung Galaxy devices, so I know a thing or two about pressing buttons in the right sequence. But, this S21 is kicking my tail. It's sooooo much is a trainwreck that I have decided that Samsung does NOT want my money, so I'll be happy to never give them a penny more. But. My friend has this $1000 turd so he's got to get it figured out. So. Please. How do I get into recovery so I can wipe the cache partition on this pile of junk?
Build number is G998BXXU2AUBB.
As a side, this problem exists on his S21, my Moto G Stylus, and his Galaxy Tab tablet, but it does NOT exist on his LG Stylo 3, so I'm pretty confident that even wiping the recovery partition will not solve the problem, but if you've ever dealt with tech support, you know that until you do the next useless troubleshooting step, they won't move on to try to actually solve the issue. So, I gotta do it.
Turn off the device.
Then boot with both the power button and the volume up button pressed (and hold them) until the phone boots to recovery.

In my experience this only works if the phone is turned off and connected by a USB-cable to a computer. If it doesn't sense the cable connected it will just boot to normal Android OS.

It's funny that several websites forget to mention this, they just write about the key combination and rebooting, but without the cable being connected to the PC it won't boot to recovery.
on most devices you dont actually need the cable connected first and some devices do weird stuff like turn on when you plug them in. They probably dont have the actual device.

Power isn't important, storage is
Wall mount power won't work, power bank, usb storage will do.

I tried that and it didn't work for me, I actually needed to boot into a PC, or maybe it doesn't work with simple slow charge USB? I will play with this to see if it works with another power source.

Try any usb storage if you have, it will work. It doesn't need power.
Even usb c headphones will work
Aleatory YouTube videos explaining the problem and possible fixes, I don't recommend this channel, I don't know the YouTuber.
ROG2 here turns off and not power on again after gaming and charging same time (it's dead). Someone here tried one of this with success?

Hello there!
I have no experience with your problem. Just going to say that from the top. I've never torn a phone down, and when hardware components need replacing that's when I usually decide I need to pick up a new phone.
I just recommend you make sure the phone you're trying to fix like this actually needs it. I've messed with my tencent rog ii quite a bit lately and I have had the phone go completely black - thinking I had thoroughly destroyed my phone, but I was able to get it running again.
It's possible that the complete "power off" that you are reporting is the phone being in EDL mode as the phone gives no indication whatsoever that it is on when in EDL mode. As a hail mary maybe you should quickly try this before tearing your phone down.
go to this guide, and download the zip file in the main post.
Repair your ROG2 phone with EDL mode,Official firmware!
Success is disgusted by some people, and will not share any files for free in the future.

extract the zip, then go the the folder "qpst.win.2.7_installer_00453.2" and run "QPST.2.7.453.msi" - this installs the drivers necessary to communicate with your phone when in EDL mode (this may not be necessary, as your pc may identify a usb connection without this, but just to check 100% I'd install the drivers anyway.)
charge your phone for at least 30 minutes. just to make sure it's got juice.
use a DIFFERENT USB-C <-> USB-A cable than came with your phone (pick one up at the shop if you're not sure. ALSO plug your [charged] phone into your PC using the side USB port on the phone (Not the bottom usb port). This is because ASUS's cables don't seem to support flashing, so I'm suspicious if they'd work appropriately in this case, and because the side port is the only one that works for flashing and the like.
now open device manager (press windows key, type "device manager"). with that screen open, plug your phone in. On device manager you're hoping that a device appears under the menu "Ports (COM & LPT)" probably named something to do with Qualcomm.
if nothing shows up, unplug the usb port from the side and hold all three side buttons down for 20 seconds (vol +, vol -, and pwr) and keep an eye on the upper left side of the device where you MAY see a red light flash indicating signs of life. then plug it in again. if nothing happens unplug the phone, and hold the power button for 5 seconds, and plug it in again. if nothing happens, unplug it and try holding down just power and volume up for 20 seconds, then plug in again. If nothing happens, try power and volume down for 20 seconds, then plug in again. (you see where I'm going?) just make absolutely sure your phone has a hardware problem and can't connect to your PC in any way before performing surgery. If the device does show up under this "Ports (COM & LPT)" device it means your phone OS is thoroughly trashed. check out that same guide I linked, as well as this youtube for some ideas how to get it going again.
If your phone doesn't connect no matter what, and you're certain you've gotta get into the hardware, then I wish you the best of luck. I really wish I could be of any further assistance with regards to hardware. maybe if you do take that road let us know how it goes.
good luck!
