Dear developers in this forum,
My tab was really in bad condition now and i have no idea how to fix it. i had searched across every thread to find the solution, but there is no method work for my case.
Its suddenly reboot and stuck at logo glalaxy tab 7.7 and keep reboot itself.
I tried to flash several rom via CWM, but all stuck at boot animation. I cannot flash new firmware via ODIN as my usb port got problem, plug it in any computer only get message usb not recognize even i sure drivers was alr installed in that computer ( someone said my usb port was damage).
what i can do now is enter CWM (version 5.2), wipe all data/factory reset, wipe cache, but cannot wipe dalvik (nothing happen when i selected it). I also can flash zip file via CWM. This set was bought in Hongkong, sim card reader spoiled twice and replaced new one. Now the usb port also spoiled
please help me here, alr few days trying to find solutions before i post this thread.Really appreciate for any suggestion.

7th post. Try from Odin, not CWM.
I have a Xperia S running cm 12.1 with unlocked bootloaders TWRP installed and i tried to partition my SD card [http://forum.xda-developers.com/showthread.php?t=2584759] but clearly something went wrong and now the phone wont boot. I made a lot of research and tried everything but all the guides require to be able to boot into flashmode . My phone is dead the only sign of life is a red led when its charging which after some hours of charge will shut off. When the light is off and the phone connected on PC, the PC can recognize the device on unspecified devices (QHSUSB_DLOAD). i have installed all the needed drivers from Sony, google drivers from sdk, and adb drivers(adb wont see the device and i tried everything to do so, but nothing seem to work). I got a market for android on my pc called mobogenie that when i connect the phone it detects that a phone is connected but wont see what phone.The hardware reset buttons work but its useless in the current position. Concluding, the phone is bricked and wont open in fastboot-flashboot-bootloader-TWRP, its recognized as a device but not as "Xperia s" i got all the drivers and i want to flash the original firmware (already downloaded) to fix it. A possible problem is that the partition table is destroyed and after the flash it will hopefully be restored. The problem is not on the hardware but on software. I tried to trigger the download mode with the Samsung way (USB jig, 300k ohm ) but nothing happened as expected. Every solution i found required flash mode which is not accessible at the moment and i tried lots of things to go into fastboot(ever the rubber band trick,remove the battery etc). PLEASE help i dont know what to do, please help me flash it (i already got flashtool, Emma) or anohter solution. Thanks for the help in advance. (its my first thread in the forum, i hope to post it on the right section, i posted it here because i need the assistance of the developers i guess)

Hi guys, after many tries, many googling and youtube research, I dicided to share my problem with our community
1. At sunday, my galaxy tab started to restart continuously, It was recharging and I took some time to see.
2. I tried to activate USB DEBUGGING but when It Restarts, it's usb debugging is disabled again.
3. I'm using Stock Rom Again...was;
4.Using Stock Recovery.
5. Tried to install many others recovery's with odin and it seems to be ok but after a restart, its all back to stock recover.
6. Tried to install Stock FW again by Odin and its stuck about 50% FAIL
7. Tried to install CFW and Other Roms by SD Card but it shows a messege "Failed to check Signature" aborting... maybe because of stock recover.
8. Not rooted, usb debugging DISABLE
9 Tried to activate USB Debugging by odin, installing a patch, without success.
10 Samsung KIES does not recognize it in Download Mode.
11. I have samsung drivers installed.
one more information, when I start in recovery Mode, it shows first an android pic and a messege NO COMMAND, then proceeds to RECOVERY(STOCK).
What Can I do?? I Did Everything I can find on Internet. Is there a phisical problem??
Best Regards!!
Seems like a similar issue like mine. Check my post about behavior of my tab 2 7" (P3100) at https://forum.xda-developers.com/galaxy-tab-2/help/p3100-16gb-bricked-emmc-bug-to-t3707134
If you have symptoms similar to mine or any mentioned in the links in the post, then it seems you have a faulty emmc (internal memory).
The only solution i get to hear up till now is either to get motherboard replaced from service center or get emmc replaced from repair shop or get it jtag'ed.
Other solutions, which would avoid jtag or other service, like dual booting from SD card existed here in xda for p3100 but having stuck in stock recovery brought limitations.
If possible share all things you tried and solution if you found any.

Tks for the answer, I guess we have the same problem, by the way, I already read your topic (lol), Surelly I'm gonna find some technical assistance , the hard thing is to find these kind of stuff, but let's see. I'm gonna share any solution, see ya!
If you install a custom recovery and then reboot to system, it will automatically install the stock recovery again unless you are rooted. To avoid this uncheck the "reboot system when finished" box in odin and after installing the recovery boot directly into it.
Stock recovery is only for installing official updates, not for custom roms. You need a custom recovery for that.

Thanks, but we I tried this too. The issue is possibly our emmc is gone into permanant write protection state as far as i have studied. i tried unchecking the "reboot system when finished" box and even pulling battery after getting odin status as success for recovery as suggested in some threads but nothing helped.
Even if i do a factory reset from recovery all data would remain as is, nothing deleted!
@blankfile99 i agree its hard to find stuff, for me jtag service is more than 500kms from my place!
I am searching for any possibility to boot from external sd card. The thing existed for p3100 (one mentioned here https://forum.xda-developers.com/showthread.php?t=1866675 which allows sd boot) and the other is the blackhawk NEXT https://forum.xda-developers.com/showthread.php?t=2285366 but this is not suitable for our case where no modifications in emmc contents are possible. Devs were able to carry out sd boot for nook color tab .
But again I am stuck trying the dual boot mentioned above at how to flash the sd boot build rom zip file to sd card since stock recovery gives signature verification failure....
Great struggle to keep the tab working...

I had the same issue - here is what I did (I'm writing this as much for me later on, as for you!). This should be fine for your device - but of course, the usual "no guarantees" applies.....
I assume you have downloaded the appropriate files ?
- I used philz_touch_6.57.8-p5100.tar.md5 (google it)
- Odin3 v1.85
1) Install / Start Odin on computer
2) Start device in download mode For my P5100 - I held down power and the UP volume button.
3) Connect USB cable to computer. In ODIN, Click PDA and select the downloaded philz_touch_6.57.8-p5100.tar.md5 (or whatever you're going to use).
4) in ODIN - UNTICK "Auto- Reboot" and Re-Partition is unticked - leave Reset Time ticked.
5) Click start. you should get the "PASS" All threads completed.
6) Disconnect USB cable
7) - important bit - Press and hold down POWER and Volume DOWN together at same time for about 15 seconds. This hopefully will restart into PhilZ mod.
Let me know how it goes.
I have decided to install custom rom on my Samsung tab 2. but it's not connecting with my laptop(not recognized).I think there's a driver problem because in device manager It is showing "Unknown USB DEVICE". Can anyone please send me the Samsung tab 2 gt p5110 driver software or any folders which are use to connect. (I have tried many times but I can't find a good solution )
@Sura 102005
Have you tried reading and following this - also read the older threads
You may need to install Samsung kies
You should also try with a newer / different cable as that could be the issue. I had this same problem and when I swapped to newer cable it solved the issue. Just try different things.

Hi clappertrap, Thank you for your kindness. I have tried Samsung Kies but I haven't tried a different cable I have order for OTG cable and USB male-male cable. I think this will work.
Hi
TF300T JB 4.2.1
Bought new in the US in 2013 so has US SKU. Originally for my wife, but she now has an iPad Pro so I've got the hand-me-down!
Wiped it and unlocked the device successfully using the Asus V8 utility. Tried to flash TWRP from Win7 computer but something went wrong. The interface was still there, it would boot up okay but there was no sign of TWRP. Eventually, I went into fastboot and selected RCK. Nothing happened except the icon turned brown and just sat there. Then I tried a factory reset but it wouldn't have any, nor a cold boot. In desperation I turned the device off and tried to reboot. The initial "Asus" screen came up ("This device is unlocked" in top left-hand corner and the 'Nividia Tegra' logo in bottom right. No spinning circle of dots). It won't boot into fastboot, in fact the volume keys are totally unresponsive. On/off will turn off the device, but it immediately boots back to the same Asus screen. It's not recognised by the Win7 computer so I can't flash anything to it. I think I've tried everything this forum (and a few lesser ones!) could suggest, to no avail.
I believe I now have the proverbial 'bricked' tablet.
Nothing daunted, and not prepared to involve Asus support, I'm considering swapping the motherboard (I've done a couple on Windows computers) but will this bring my TF300T back to life, or is there more I need to do?
I'm no expert on the Android OS so any help from you experts would be much appreciated.
Thanks in advance.
Anyone?
I know the TF300 is a bit long in the tooth now, but all I want to know is whether a bricked one can be recovered by replacing the motherboard. There must be someone out there who has done the replacement and can advise me? Also, I apologise if this in in the wrong section, I guess it should have been in the 'Help' section, but I didn't realise until I'd posted it.

Of course, exchange the MB will bring back your device to life. But it is really the last option.
Firstly you have to check patiently if you can get access into your device. Therefore read mindfully this thread:
https://forum.xda-developers.com/showthread.php?t=2396072
"The solution by @Buster99 is for those who:
- flashed the wrong recovery, and wiped data
- are able to boot into recovery, but cannot flash anything
- no adb access (although, if you DO have adb access, this will still work for you...)"
Hopefully my advise will help you! Don't forget to thank @Buster99

ebonit ~ many thanks for your response. Unfortunately, I really don't think there's any way I can get access. The initial boot-up screen is all I get, in perpetual loop. The only way to shut it down is reset with vol-up., though it's possible it may be in some sort of variation of apx mode at this point as the screen is blank. I've no way of knowing as my win 7 computer only acknowledges an 'unknown device' at that point, and nothing when the initial boot screen is there. Vol-down doesn't seem to have any effect at all. Windows has already installed the drivers so won't re-install, or uninstall them as it's 'unknown'. I did once manage to get it recognised as an 'apx device' but with an '!' (not sure how I did it as I haven't been able to replicate it since!) but I don't think that helps me even if I could replicate it without the '!', Nvflash requires I have the necessary back-up files, which of course I don't. I don't know where to go from here except to replace the motherboard. Once I get the device apart I may try disconnecting the battery, vol-down, and reconnect, to try booting to recovery, but I'm not optimistic of that working.
I'll certainly be very happy to consider any other suggestions you, or anyone else, may have.
I tried Buster99's method, but as my TF300T isn't recognised by Windows that was a non-starter.
Once again, many thanks for your input.

I'm sorry, but if you are really sure that you cannot boot into either fastboot or recovery the tablet is bricked for good!
In this case to replace the mainboard will be the last option to get the tablet back to life. There is a very good instruction with pictures by @huebinger that shows you what to do exactly: https://forum.xda-developers.com/showthread.php?t=2368372 (BTW, that's what I did many years ago!!!)
On ebay.com you may find a used one:

ebonit ~ Thanks for the links. I checked out huebinger's and pulled my motherboard out, then bought the one you linked to on eBay. Hopefully, I didn't do any damage getting the MB out. I'm more used to the tough old internal wiring of desktop computers!
I'd already backed up the data and done a factory reset before I began my abortive attempts at rooting so hopefully I'll be starting with a clean slate once I get the new board installed. It's going to take a while to cross the pond to France, but I'll report on how it goes once it arrives.
Thanks again for your help, it's much appreciated.

Hello,
My tf300t got bricked while upgrading twrp.
nothing helped, i put away the tablet, after a year i found her ... so i said to myself "why not" ?! so i ordered from ebay a motherboard, and it's work like a charm, but the tablet is old now ;0
now i want to setup a lite rom ....

I was wondering that, too!
It's good to know the s/h motherboard cured his tablet's ills, though.
My replacement motherboard arrived yesterday and is installed, up, and running.
Android Ver: 4.2.1
Build No: US_epad - 10.6.1.27.5
I downloaded the v8 unlock device app and unlocked the tab.
I've downloaded:
1) djibe Transformer Pad TF300T pack v3
2)KatKiss -7.1_TF300T_029
3) open-gapps-arm-7.1-pico-20180517
I have a 32g microSD formated to FAT32 installed in the tablet.
All as per djibe89's tutorial here: https://forum.xda-developers.com/transformer-tf300t/general/guide-asus-transformer-pad-tf300t-stock-t3554744
My 'versions' are identical with djibe89's except for the BT version which is 11.38, not 10.38. Hopefully that'll not affect anything!
At this point I run into problems:
1) My USB link between the win 7 (32-bit) computer and the tablet is iffy. Sometimes it works for a while, but I frequently get the "USB device Not Recognized" with a useless MS message not worth clicking on. I'm wondering if there's a more reliable way to transfer files? Airdroid, possibly? Losing connection during file transference doesn't bear thinking about.
2)
Go to folder /Universal Naked Drivers 0.72 you unziped at start on your Desktop.
Select file android_apxusb.inf, then right click -> Install.
Force driver install and wait until a success message prompts.
Repeat operation with android_winusb.inf .
Click to expand...
Click to collapse
I tried installing these drivers by both right-click-> Install and also CMD. -to no avail. I get a Windows message saying the best drivers for the device are already installed, but the tab still isn't recognized. Oh, yes it is! Ooops, now it isn't! ad infinitum, I'm guessing.
Can anyone advise how to overcome this or I can see myself keeping the used motherboard salesmen in Mercedes for the next decade! :crying:
3) Assuming I can overcome the iffy USB problem: should I use TWRP Kang 2.8.7.2 or TWRP 3.2?
I guess that's enough problems for now. I hope ebonit or some other expert can assist with this as I really want to get this tab rooted.
Thanks

Congratulations! You did a good job. Thanks for your report.
First of all, to avoid any issues to get your device on N 7.1 Nougatella please follow exactly Tim's install instruction step by step in post #1. https://forum.xda-developers.com/transformer-tf300t/development/rom-t3453702
You need Kang TWRP as advised by Tim. Don't forget to format data through Kang TWRP before. It takes up to one hour. Then change file system to F2FS for data only no cache and system. Successfully done your device is now ready to install Rom, pico Gapps and SuperSU fresh downloaded via Tim's links there.
PS: About your USB issue take another USB port on your PC not via hub!
Good luck!
Three days with nothing from me, you'd be excused for thinking either I was dead, or my tab was! Thankfully, neither. In fact - SUCCESS!!! We're both alive and well, and for the tablet at least, performing better than ever.
TWRP installation took me two days. First, the computer (Win 7 32-bit) refused to recognize the TF300T and 'fastboot' could have been renamed 'nerverboot'. Strangely, the whole business seemed to evolve over time. Persistence was the name of the game - trying different USB ports, booting and rebooting (both tab and desktop). Eventually I found Snoop05's '15 seconds ADB Installer v1.4.3' https://forum.xda-developers.com/showthread.php?t=2588979 and with that I began to make progress...slowly!
Code:
fastboot devices
returned '???????????????' over and over again. By uplugging/plugging the cable into the tablet a few times I suddenly got a nice long string of letters and numbers. It came and went a few times but after a while seemed to stabilize till I felt ready for the big push of TWRP. I got so many error messages: 'can't find twrp.img' (I'd renamed it); 'can't open twrp.img'; 'insufficient memory', etc, etc.. Suddenly, it worked. It took just over eight seconds to download the 6.95MB. Booting into recovery was rather heart-stopping, but it came up a treat.
After that it was relatively simple to set up the TWRP (I found Djibe89's guide https://forum.xda-developers.com/transformer-tf300t/general/guide-asus-transformer-pad-tf300t-stock-t3554744 especially useful and there's a copy in the -djibe Transformer Pad TF300T pack v3' http://bit.ly/djibe-tf300t-v3.
Flashing KatKiss 7.1_TF300T_029, open_gapps-arm7.1-pico, and SuperSU-v2.82 from the microSD I'd copied them to went like a dream and before I knew it the old tab was humming with life once more. I'm a very happy chappy!
I have just two queries (so far ) 1. djibe89 mentions the file 'deviceID.apk' but Tim doesn't. Is it still necessary? I believe it's to keep Google happy, but I've no problems downloading from the Play Store, so I've not installed it as yet.
2) While installing the 'Battery Calibration' app it briefly stated that the tab wasn't rooted. I assume if I've achieved all the above, then it must be?
Now I'm going to play. No doubt I'll be back with a few more queries before too long!
Special thanks to ebonit for his help and support.

To avoid any issues please reinstall your system by doing a Buster99 https://forum.xda-developers.com/showpost.php?p=44244313&postcount=12. Be sure you have the latest firmware "WW_epad-user-10.6.1.27.5"
After that delete your Google account. Then you may unlock your device with V7.

Hope you have Kang TWRP now as required by Tim in post #1!
I'm sorry, but you never mentioned that you cannot access your Tablet via ADB. Therefore please note, the best ADB tool, every Android user may have on his PC, is "Minimal ADB & Fastboot" https://forum.xda-developers.com/showthread.php?t=2317790.
BTW, the answer to your first question is nope, you don't need it. The answer to your second one is yes the device is rooted. However check the update status of your SuperSU. Hope you did fresh download Rom, Apps and SuperSU via Tim's links in post #1 of the Nougatella thread?
I have installed Kang TWRP 2.8.7.2 as per Timduru's link. My tab was wiped before installation so all apps were fresh downloads. SuperSU was 'UPDATE-SuperSU-v2.82-20170528234214.zip' again, as per Timduru's link, as was the ROM ' KatKiss-7.1_TF300T_030.zip'. Many thanks for pointing me to 'Minimal ADB & Fastboot' which I've now installed for future use. And many thanks for all your other help. No doubt I'll be back for more!

You are welcome! It's good to hear that you did such a good job. Using the thanks button is always greatly appreciated.
Please note, if you have any issues or you are changing the Android system, Format /data through Kang TWRP is always required. Format /data is more than wipe (you did wipe!) or factory reset. It takes up to 1 hour to be successfully. After that your system is really clean.
"Warning: formatting will remove what is stored in your internal storage, so store the rom /gapps/supersu zips onto an external storage (microSD, SD card..) or make sure you know how to push them back through adb." advised by Tim in post #1.
