[Q] LG D802 PWR button not working after recovery from HS-USB QDLoader 9008 mode - G2 Q&A, Help & Troubleshooting

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

Can't unbrick Optimus l5

Hello, I ran into a problematic brick on my L5...nothing seems to work to unbrick it.
I followed the guides step by step using the KDZ updater and the appropriate firmware for my country, but it doesn't work.
How I bricked it:
I had CM10 installed and perfectly running for a month, so today I decided to attempt an overclock to speed the device up a bit.
So, I downloaded and installed the modded kernel, flashed it using CWM and rebooted the device. After that, the device just keep booting up, showing the LG logo and then a black screen.
Now, after trying to flash the old firmware after going into download mode it just stops on the LG logo with the flare (sun ray effect) spinning around the logo all the time...It's been like that for almost 30 minutes now. I attempted re-flashing it 3 times but nothing seems to work.
What do I do?
Thank you in advance.
It's bootloop. When I had L5 I had the same problem after flashing bricked phone via KDZ.
Do hard reset with key combination. It worked for me. Phone will boot up few minutes.

This is what I get when I connect the phone by USB.
I just cant get into emergency, DIAG or emergency CS
KDZ the phone connects and then I get a message afterwards PHONE NOT FOUND.
everytime I install the drivers by LG support tool, it keeps giving me the option to install the driver, like I havent done it a hundred times over.
I think there should be a driver somewhere that can be installed but the only people that have this driver are LG tech's. So they can bill you after
send the phone in cause you rooted it. So the one billion dollar question is witch hero will find a way to unbrick this device. We only need a way
to get a driver to install and we are home free. Or maybe the only other option is throwing the phone for sale on internet for spare parts
HELP PLEASE HELP find a way to unbrick this phone. Believe me I flashed and bricked alot of different phones and there was a way out but in
with this phone it seems impossible!!
And there is no mode to put it in in because te volume buttons don't do crap, the home button also, the only time that the phone does show up is when windows tells me it has an unknown device that I for the love of god can't find a driver for. I tried SDK, the LG drivers, but no dice
Did you try emergency mode? (volume up + volume down + power button)
If not, see if you can enter it and then flashing your stock firmware with Software update [KDZ] 1.0.4.4 (KDZ-Flasher).

Samsung S4 Fullbrick

Hello, first, sorry for my bad english too :\ i'm french
I'm posting this for a friend, unfortunately it is not good at phone and do not understand English. I therefore support myself (by teamviewer).
His phone was purchased in France, he received yesterday, phone clearly worked well, apart if I understand an error message: "Process.android.acore stopped." He tried to update it to Android 5.0.1 (by about => Update, and in my opinion, that's where the problems have begun, its connection is really not stable at all, she interrupted constantly and is also very very very slow, sometimes I wonder if it exceeds 50k / s ... He told me that during the update, he went to see his friends, ( + - 3h download ...) he put his phone on charge a few hours later, he returned home and the problems started and His phone was put out .. It no longer able to restart it.. told me there have no signs of life, here is what has been've already made.
-> Press VOL +, HOME and Power at the same time to get in recovery: No results
-> Press VOL -, HOME and Power at the same time to set download: No results
-> Remove the battery, sim and sd, and press 30sec Power: No results
-> He tested his battery on his brother's phone (also S4) it works, he tested his battery (his brother) in his phone: No results
Nothing appears on the phone, black screen and no LED ... I told him that his phone was probably a DOA (Dead On Arrival), however, I still tried to help because it m ' You said the phone will require three months to repair ..
After more research, I saw that his computer recognized the phone as Qualcomm HS-USB QDLoader 9008. The phone is completely bricked, can you provide me with the necessary files and tell me how I should proceed?
Thank you
If's a SAMSUNG GALAXY S4 I9505
I had the exact same problem with the pc only recognizing qualcomm...
I'm afraid to tell you that the partitions are probably corrupted i gave it to my provider back then which took them 2 weeks to repair i think they switched the so called emmc even though i had knox 0x1 and root so better send it back/ let the seller give it to repair because the waiting time was really killing me xD.
I saw tutorial like this http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830 and other to rebuild partition, i'm sure it's possible, but i need help ^^
This is about as bricked as it gets, and software likely isn't going to fix it. This same issue has happened on the Galaxy SII and they haven't found a solution after nearly four years of trying. The phone needs to be serviced.

Bricked A2017G B03 - help please

Hello!
As title says i bricked my Axon :crying:
I followed http://forum.xda-developers.com/showpost.php?p=68738854&postcount=100 (and the german one that linked to this one) but couldnt do the fastboot unlock.
So i couldnt finish this and my phone required a pin number to start android: bootet and started up but wanted a pin code to start/enter system.
Wasnt able to fix that with googling for answers so i went back to edl mode and rewrote my backup boot/recovery images with axon7backup.
Had no errors with that but it wont start now:
After the ZTE Logo the display goes black but it connects as "handset diagnostic interface (DFU) (ComX)" to my computer.
I fiddled around with driver installing etc and forced the HS-USB QDLoader 9008 on it but no luck, axon7backup/root can not connect.
When i did the actual flashing yesterday it never connected with the hold both vol-keys and connect usb way either, always had to reboot into edl via adb.
I cant boot anything else (no twrp/recovery) it just goes to the diagnostic interface mode.
Thanks in advance
you can try to get into adb mode with this:
- power off your device
- hold the vol down key while plugin in the usb-c cable (connected to your pc)
- keep holding
- you should get a white box with FTM factory test mode
- you are free to use adb again - so you can get into edl mode as well....
for pin part that'S normal while unlocking your device encryption gets deleted and you have to abort and factory reset your device in twrp....

Thanks. I tried it but it wont go to FTM. Only goes to diagnostic com port.
It seems i cant even turn it off. The little red light on the front is on the whole time .
sadly the disadvantage of a built in battery, so you have to wait till the battery is empty and try my instructions then....if it's not realy off it won't work, the mode you are currently in you usually only reach if you switch it on while holding both volume buttons, the edl mode is sadly not reachable with a key combination directly on G models.
adb don't show your device?

Oh ok. I expected ftm to work from vol-down and power-button till restart.
@adb: sadly no connection possible since it goes straight to Comport Connection.
Edit:
Couldnt make that work. It was off and i connected the usb. So it showed me the loading battery picture where i cant do anything. held the vol-down the whole time. But as soon as it had some battery it went straight to comport-connection again
im sorry to say, but ur device is bricked to a degree where you would need ZTEs Flashtool to fix it. Unfortunately we dont have that tool, so you might have to send it in
i have the same exact problem :'(
Have u been able to fix it?? I'm in a situation that i cant even send it to ZTE to fix it :'(

Hi,
couldnt fix it myself so i had to send it in.
Unless some tool/rom was released in the last few months to fix it yourself i would guess your device is bricked.
Hi I have almost the same problem, I tried to unlock bootloader and now I don't have the recovery, I can boot and use my mobile but I can't restore it or update it because I don't have the recovery
I try whit axon7tool to restore the recovery but I got a error.

Hi, do you have any idea, if there will be such a flashtool to work with DFU mode? I'm thinking that there are a lot of guys have bricked their devices (including me).

SM-950F Hard bricked, JTAG?

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.
http://a2zcellular.com/
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

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.

Samsung S10 + bootloop ERASE FAIL: READ ONLY

Samsung S10 + SM-F975F/DS IMEI stating Taiwan (Update: Very contradicting information if the phone is Snapdragon OR Exynos) if it even matters to solve the issue I dont know
Owner of the above since 2019 without issues; USB debugging mode activated in 2019 and never changed since then.
Samsung always updated which I assume the UI 3 Android got updated in January of my vague memory/recollection (honestly never paid attention of what is being updated, only that the phone needs to be on charge while doing ANY update)
Issue: phone in constant bootloop every 4 minutes with top message in red color "ERASE FAIL: READ ONLY" see photo attached
Cause: happened 4 days ago: Watched video stream on chrome browser; phone froze and applied a 10sec. power shut off (never had to do that before, 1st time)
Investigation:
I tried (found out by doing so) to interrupt the bootloop with pressing Power button and same time Volume Down Button in order to restart it and follow the following commands found on the internet as per UI 3 update:
Recovery Mode as followed does nothing:
Hold the Power button of your device till the power menu pops up and select Power Off. = does not apply as in bootloop
Wait for your device to turn off completely. = it does never turn off completely UNLESS I press Power button and same time Volume Down Button und plug into USB C Data cable of which the charging circle with the lightening strike appears without any percentage % of which photo is attached (phone charge can keep up with its bootloop in order to avoid battery drainage as there is no % indication)
Plug-in a USB-C data cable connected to your PC or USB-C earphones in your device. = I start from here whenever the phone restarts every 4 minutes or whenever I do it manually by pressing the buttons as I described in point 2.
Now, check if your device has a Bixby Button (Such as Galaxy S10/Note10):
Without Bixby Button: Press Volume Up + Power Button for a few seconds.
With Bixby Button: Press Volume Up + Bixby Button + Power Button for a few seconds
After the above steps, you will boot into Recovery mode.
Download Mode as followed does nothing: IT DOES WORK NOW you need to be very fast before the phone starts (recovery mode does not work)
Make sure you have a USB cable connected to the computer
Then press and hold the Volume Down and Bixby buttons at the same time
Continue holding these two buttons down while you insert the USB cable that is connected to the PC
Recovery Mode before update instructions as followed does nothing:
Step 1: Start by turning off your Galaxy S10.
Step 2: After it’s powered down, press and hold Volume Up button and Bixby button (this is the button underneath the volume buttons in case you didn’t know).
Step 3: Without letting go of the Volume Up and Bixby buttons, press and hold the Power button.
Step 4: As soon as your device turns on, let go of the Power button.
Step 5: After you see a blue screen, let go of the remaining two buttons. Now you are in Recovery mode.
Download Mode before update instructions as followed does nothing:
Step 1: Turn off your Galaxy S10.
Step 2: When it’s turned off, press and hold the Volume Down button and Bixby button.
Step 3: Without letting go of the two buttons, press and hold the Power button.
Step 4: You will get into Download Mode.
Have tried all the above methods several times the past 4 days.
Have drained the battery in terms of keeping the phone in bootloop resulting in no power.
Unhooked the battery by means of removing the rear panel and unhooking the battery cable for more then 15minutes and repeat the 4 different methods
Unhooked the mainboard from various connections and put together and repeat the 4 different methods
No indications in Windows 10 Device manager
Questions, doubts and thoughts:
Is it possible in this state to access with ADB of a professional in order to perhaps clear the cache, resolve the issue without having access to recovery mode?
Should I simply try to purchase a new battery even though I never had any battery issues?
I am aware that a motherboard change will resolve it to the cheapest way possible but as I like to save the data such as different accounts this is not an option besides the phone is physically in good condition (never went under water or dropped). maybe to unsolder the flash memory onto a new mainboard as recovery mode might be part of the processor where the RAM is saved.
Any way to drain the entire phone further which may resolve the issue without loosing data. Similar in removing a CMOS battery on a PC mainboard and using a jumper.
Willing to pay and currently living in Europe.
UPDATE: Odin firmware performed by skilled professional member of xda forum, but still not working. EMMC issue which needs to be addressed with ISP in order to fix the issue. unfortunately I was told by local professionals that they do not have the tools for it. Therefor I wonder if someone knows someone who knows someone who can be of help. Location is Spain but Europe would also work.
UPDATE2: Got the phone back from technician who has experience with ISP but still same Error remains as to his conclusion that this is not an Exynos phone of which he has not the hardware tool to fix it and probably no one in Europe will have it.
Thank you very much in advance
Sorry... my english not so good...
so the point is whether you can enter recovery or download mode or not ?

I am not sure but that person who helped me remotely may explain better
According to technician its Qualcomm Snapdragon which can only be fixed with the right tools. Not in europe.
I been getting different information and do require some expertise if someone can please help me
any further advice, input or suggestion?
I also Own Samsung S10+.
its showing the same thing.
tried Flashing Via Odin it failed.
Tried to enter Recovery Mode but also failed to enter recovery mode.
OMG. I thought I was the only one in the world. I sent it yesterday to a data recovery technician to see what they will do since according to some insider in order to recover the data they would have to access the phone and fix the boot of which the problem get solved itself since they can not remove the memory chip itself as it would get ruined. They will diagnose the problem first before they do anything. Obviously a mainboard change would be the easiest but thats not an option.
Was your phone also updated to UI Android 3.0?
How did it happen if I may ask?
I wont give up since my phone is physically totally fine.
Update from a data recovery company its communication:
What we tried to do in order to recover your device's data was to load through the phone's bootloader (in Download Mode) a software agent that allows us (in some cases) to transfer the data stored in the data partition. This software agent has been developed by us together with some of our partners and as we are sure you will understand we cannot give you more details about what this particular software does or how it does it, since this information is covered by professional and business secrecy.
In this case the phone's firmware was damaged to a degree that made it impossible for the information to be accessed with this software.
At this moment, we doubt the data could be recovered by any software available now in the market. That's our opinion, but you can of course send it to other companies to see if they can recover it.
Since I am not the only one anymore with the same issue I recommend for people to come forward in order to get help
So far there is a tool needed to reprogram EMMC but I dont know which tool neither do I know where to find that person with this knowledge

I honestly dont know anymore since numerous people said contradicting things.
I am under the impression it is Exynos as of the research of the model SM-G975F/DS
Need to know exactly if it's Snap or not. If it is, then there're 2 options you can try.
1. Ask some one have the same device model as you, do a ROM dump ( you can google for more detail ). Once you got that, I can share with you the tool needed for restore your device from that dump.
2. Try find your device's Factory Images ( similar to Fastboot ROM, but a little different ), and an authenticated prog of your SoC ( this I can share too if you choose this option ) then boot your device into EDL mode by using fastboot2EDL script ( on Git, you can google too ) then use QFIL ( one tool in QPST Tools by Qualcomm ) and force flash the images into the device.
So far as my experience and understanding, there're only these 2 solutions to fix your device ( if it's Snap powered ).
According to the seller: "The phone is Taiwanese version and CPU should be Exynos 9820"
Maybe someone can help me please.. still
If its Exynos powered, then I have no solution for it. Sorry bro!!!

Try find your device's Factory Images ( similar to Fastboot ROM, but a little different ), and an authenticated prog of your SoC ( this I can share too if you choose this option ) then boot your device into EDL mode by using fastboot2EDL script ( on Git, you can google too ) then use QFIL ( one tool in QPST Tools by Qualcomm ) and force flash the images into the device.
So far as my experience and understanding, there're only these 2 solutions to fix your device ( if it's Snap powered ).

Hi mate, My phone is Snapdragon powered..
My problem is almost similar.. But not exactly.. After almost 2 months I am not able to find a solution.. But after this period of researching and googling about things related to my problem.. I feel now, either any one of the following is the cause of problem:
1. Emmc is stuck or locked in read-only mode `(Can move files from pc , delete already present files anywhere in any directory, but all changes vanish after reboot... all file and directory structure remain intact- moved files from pc gets deleted.. and deleted files which were already present come back after reboot )
2. Corrupted /data and /cache partition, as e2fsck in twrp terminal results shows "filesystem still has errors" and "e2fsck: unable to set superblock flags on /dev/block/mmcblk0p** ) in both these file system (I think they are preventing flashing procedures- Odin stock firmware flashes and twrp custom ROM flashes both are successful, but after reboot no changes can be seen... - Even Recovery.img and boot.img flashes don't seem to work even both are shown successfully flashed in twrp) After reboot current version twrp boots again instead of newly flashed different version recovery.img ... same with boot.img even after running magisk uninstaller zip files.. running uninstall.zip 2nd or 3rd time also shows magisk patched image detected in log which should be removed in 1st iteration itself..
3. Might be magisk is preventing these changes to be made.. or It might be the /System_root creation as mountpoint for system partition which used to be previously /system normally. This might be the superblock creation which not used to be there
My Samsung's twrp and Download Mode seems to be working but no changes made by them even after successful operations by both.
Can you suggest anything? You can look my thread as to get even more detailed overview of what's happening and whatever I'have tried here - https://forum.xda-developers.com/t/...t-not-changing-anything-after-reboot.4462639/
You can see my attachments in my above thread to see my directory structure of system_root and my download mode pictures and odin system ROM flash pictures.
