[Q] Is my Tab done for? Is it fixable? Help!

I'm having the following problems with my TAB and would like to know it's fixable. I treid almost everything to fix it without success. I'm hoping someone can help me. Anyone have these problems before?
1. Doesn't charge normally. It would charge but charge really slow like it's connected via us. It shows an x next to the lightening icon when I charge it using the original charger and cable.
2. I cannot go into recovery mode. I get the black screen with the white line. There's also no boot animation when it boots up.
3. The camera doesn't work. I get a fail message when I open it.
4. My computer doesn't detect it in download mode, kies or mass storage. My computer detect my samsung galaxy s i9000 without any problems so I know it's not the computer. I cannot change the firmware because my computer doesnt detect it.
5. I dont have the receipt to do a warranty repair. What are my other option?
AT&T SGH-i987
Firmware 2.2
Baseband P1000XXJHA
Kernel 2.6.32.9 [email protected] #19
Build XXJMA
Any help is much appreciated! Thanks!

Did you register your Tab with Samsung?
If so, they have a record of your purchase and will be able to provide support.
If not, then try this which I got from their online chat: Hope it helps.
"Kyle: To recover the device via the hardware keys, do the following:
Kyle: 1. Power off the handset.
Kyle: 2. Hold the Vol Down Key + Vol Up Key + Power Key for 15 seconds then release.
Kyle: 3.When the recovery screen comes up, use the volume up key and volume down key to navigate through the selections and the power key to select item.
Kyle: 4. Select Delete all user data to recover the device. To confirm, scroll down and select Yes – delete all user data. The phone reboots and again displays the recovery screen.
Kyle: 5. Select Reboot system to restart the handset again. "

Thanks but I cannot get to that recovery screen like I said above. All I get is a black screen with a white line when I try to go into recovery mode. I also purchase this used with no receipt.

U just need to flash a working rom. Try roto jm... in the dev forum
Your tab was modified. I wont blame Samsung if they wont fix it for u

How do i flash to a different rom if a computer wont detect it?

Do you have the latest kies installed? Is USB Debug on? If it still doesn't detect, have you tried android-sdk or heimdall. Each comes with usb driver. I find it hard to believe your PC doesn't detect the tab. I never heard such thing before unless you're the real first victim then...yeah, try to call Samsung and pay a fee.

Yes, I tried to use android-sdk and heimdall but they don't detect my TAB for me to do anything. I also installed the newest KIES software. I also don't understand why it doesn't detect it in download mode. This is the first time I encounter this problem. I flashed my Galaxy S I9000 phones many times without a problem. Is the combination of the firmware and kernal I have that is causing my computer not to detect the TAB?
Is there a way to root my TAB via an APK? I tried Z4Root but it's not working. It tries to acquirer shell and closes after a few vibrate. yes, debugging mode is on.

You've followed Heimdall's README and installed the included driver? Make sure you follow the instructions exactly.
If you have done that and your device still isn't recognised consider trying a another cable, USB port or entirely different PC.

Thanks for your advice but I already tried above. I didn't have any problems/trouble connecting my Verizon Tab and Galaxy S phone to the computers to change the roms. There is most likely something wrong with the Tab. I gave up and contacted Samsung yesterday. I sent the Tab to them yesterday and hopefully they won't charge me to fix it.

Removing USB connection while flashing

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!

If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

Thank you for your reply. I found this on the sticky threads: "[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2".
I installed ubuntu and followed the instructions. when I type the following: "gdisk -l /dev/sde" I receive an error message:
"GPT fdisk (gdisk) version 0.5.1
NOTE: Write test failed with error number 13. It will be impossible to save
changes to this disk's partition table!
Problem opening /dev/sde for reading! Error is 13
You must run this program as root or use sudo!"
My device is not rooted, is this the problem?
Please help me!!
Thanks

@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:
Thank you all for your support, this is an excellent forum!:good::good:

Nope it isn't the end try to install the recovery again or try to push the custom twrp recovery again to the right partition! Dont give up that fast when i hear your things then its still fixable! you already got the factory reset processing so try to Push the Recovery again and search for an guide about recovery maybe Then you would probably get your device fixed.
Just read my things about simplicity so think easy and you can fix it. AND STAY POSITIVE You will repair your phone today :good:

Did you already installed the LG drivers? and checked in device manager or there is like any change when you connect and disconnect your phone?

Yes, I checked it- no response during connecting/disconnecting the device..
Maybe I did a mistake when trying to push those image files.. I guess there is nothing I can do to fix my phone..
Do you have any other suggestions?

Can someone please help me. How can I get to the LG device- Is there another software I can use to flash files into this device?
Thanks

Sorry for late reaction but i needed to think of something. Did you tryed to use another cable? Did you tryed to do it on another pc? Did you tryed to maybe install LG PC suite and see if it gets recognized? If you have the PC Suite you may need to turn it off in the LG flashtool idk. Can you tell us more like which windows you have?

Hi,
I tried all you suggested, however my devide is not recognized. I tried to use the LG PC Suite and to flash by IMEI, however it is still saying that no device was connected.. I checked windows device manager, and nothing changed there.
There is any chnage I can see my connected device? use some tool or another software?
Thank you again for your patience and help!

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.

Issue was solved- device was fixed under warranty
Hi,
I just want to update you all that my device was fixed under warranty! (motherboard replacement)
Thank you all for help and great support, this is a great forum with great community :good::good:

Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.

My J7 is soft bricked, please help :)

Hi all,
So my J7 2017 (SM-J730FZKDLUX) basically soft-bricked itself after an official update. Everything on this phone is stock and I never installed anything suspicious on it either.
The current situation is as follows:
Booting the phone normally doesn't work as it gets stuck on the first Android/Samsung screen.
Recovery and safe modes don't work at all: nothing happens.
Download/Odin mode works.
Samsung Smart Switch says my device is not supported while it's supposed to be...
Samsung Kies does not want to start on my PC and says "Update in progress. Unable to run Kies".
Even though it is still under the standard warranty, I've been told I would have to pay for the screen to be changed since the current screen has a scratch on it...
Since Download mode works, I've tried flashing the phone by following this guide from SAMmobile (https :// www(d0t)sammobile(d0t)com/firmwares/galaxy-j7/SM-J730F/LUX/download/J730FXXU3BRL3/247119/) as well as this guide from updato (https :// updato(d0t)com/firmware-archive-select-model?record=0E6D53429C5B11E89F15FA163EE8F90B).
Both result in Odin getting stuck on the "Initialzation" phase. I've searched on the Internet and people said to remove the SD card (I don't have one in that phone), remove the battery (impossible), use a different USB port (tried all of them), be quick (I click on the "Start" button as soon as the phone is "Added" in Odin), enable Debugging mode (well... I can't boot the phone...), make sure to install the Samsung drivers (done from https :// developer(d0t)samsung(d0t)com/galaxy/others/android-usb-driver-for-windows (official Samsung site), but that didn't change anything), using an older version of Odin (but which am I supposed to use? There are tens of them), make sure that Kies is not running at the same time as Odin (Kies was not even installed at the time), running Odin as admin (this is actually required otherwise it doesn't get passed the "SetupConnection" step unless I'm quick enough), use the original USB cable the phone came with (impossible, it was destroyed by my dog however the cable I'm using fits well in the USB port of phone)...
So what am I doing wrong? What can I do? Please help me!
PS: You'll note that my links are a bit weird, it's because I'm new to xda, sorry about that.

You should use the latest odin (3.13.1) and use an official samsung USB cable if possible. Not all cables (although it fits) are wired the same.
If the problem is hardware related at least you have warranty.

Bricked Redmi 2

Hey! I've got some real issues, please read my whole story and try to help me.
So, I've got Redmi 2 (wt80047) and I have installed an custom rom i.e..Atomic OS because that was the best of all, but I was facing issues of LTE network, it automatically disconnects, and then I have to restart my phone like 8-9 times to get the LTE network back , so I decided to switch back to stock ROM, and successfully I have re-installed my stock rom (MIUI8), afterwards I have downloaded some files like Magisk.zip and SuperSU.zip for rooting purpose, but I don't know what happened but my device was bricked, it was not openinig, it was stucked at logo, it was neither going in Fastboot mode nor my pc was detecting the device so I can flash again it with MI Flash tool. The only thing that was happening was that multiples drives were showing on my windows whenever I connect my Redmi 2 to pc like E: drive, F; drive, G, H, I: drive. So i have opened an application (Disk Partition Tool) and deleted all the drives. Then my device was ****ed x100. Now it is totally dead. No response, no powering on, no vibration, no fastboot mode, but now my PC and MI Flash Tool is recognizing it with COM6 (ports), so now whenever I try to flash it. it gives me error "Cannot receive hello packet" and sometimes "Ping target failed". Please Help Me, Pleasee!
Some Things that I have already tried:-
1.Tried every version of Mi Flash Tool
2. Tried chineese and global rom version both
3. Tried QFIL
4. Tried every ports on my cpu
5. Cannot flash it with cmd, coz adb and fastboot both does not recognize my device (Waiting for device...)
6. Pressed the Power button and then flashed it.
7. Remove the battery, short the EDL points, I have tried all the hardware stuff also.
I am stucked in this for like 1 month, and I have only this phone, my parents won't give me a new one.
Help!)

Looks to me the phone was connected to Windows computer in USB-MTP mode, so the computer believed the phone to be a portable media player and/or USB-drive. Deleting partitions always causes a complete data loss. Hence it's not wondering me that the phone actually is dead: you fully wiped it.

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 ?

Thank you for following up.

Samfw.com_SM-G975F_XSG_G975FXXU9FUBD_fac
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

Your device is powered by Snapdragon or Exynos?

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!!!

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.
