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.

Thanks for your kind respond,
the thread above finnaly lead to unbrick the device via ODIN, my usb port was not work properly , so ODIN will not help in this case.
anyway, thanks again for your concern bro.
if you want to keep trying. I think this thread http://forum.xda-developers.com/showthread.php?t=1639955 and http://forum.xda-developers.com/showthread.php?t=1854207 not to bad to give it a try. Hope your computer could recognize the device. if so, I believe you can revive your tab. Thanks.
Thread moved to Q & A section, post in the relevant section next time.
Every thing was fine while my nexus s istalled CM10.
But after I install CM10.1 M2,I lost my USB connection.
I get the following when the cable is connected: "USB device not recognized".
I tried on different computers and usb cables then got same "USB device not recognized".
After I google that, They said install an app called "USB Switcher". Open it and clicked change to mass storage
and reboot. Then my computer still said "USB device not recognized".
I found the cyanogenmod official forum. There was a man got same proble. I post my story.
but did not get reply.
I thought it may be a bug with MTP transfer mod.
But I did got more information about that.
I thought it may be a bug for CM10 ,but now I intalled CM10 MOD from CM10 M2 TO RC5. Still got same thing.
So I come here for help.
Thanks in advance for any suggestions.

The problem happened after I upgraded CM10.1 CM2 from CM10.1 CM1.

i son't think it's rom related, i had the same issue with others rom, i asked here but nobody answered me... anyway i found that if you pullout battery then go in recovery fix permission and reboot it starts working again... i think it's some kind of error in the file system, propably the best solution would be to format the partition deleting all data on SD... i'm not able to understand what caused this, one thing i did, but i don't know if it's related, was using LAGFIX and trimming system and data... u can try to mount USB from recovery and see if that works, what recovery are you using ???

How to use this Philz Touch recovery?
Hi Kriout, I am unable to access my phone from my computer for about a week now. Earlier it was working fine. I tried resetting the usb ports by uninstalling and re-installing them. only once myphone (Nexus s I9020) is recognized as an unknown device but Windows 7 unable to update the drivers or find them for this device.
If I want to even go back to stock rom ( I am currently using Avatar ROM 4.2.2(android) ) as i am unable to access my phone via computer.
I tried going back to older updates of Avatar Rom to see if its the ROM which might be the issue, but that didn't work either.
I tried mounting the USB/SD via the bootloader but no use.
Can you help me please?

- you should first try to understand if it's a driver problem or a smartphone problem, try to mount USB on other pc
- if they doesn't work you should try to mount it in recovery, use TWRP, an old CWM ( in the last one this function doesn't work) or the philz recovery that u find here http://d-h.st/users/philz_touch/?fld_id=16784#files, try to fix permission, wipe cache and dalvik and pullout battery alos several time if it doesn't work. i found out that for me pulling out battery entering recovery fixing permission, shut down, pull out battery entering recovery and mounting USB often worked... you can try also using different kernel,
- my idea is that the problem is an error in the SD file system so propably the best solution could be formatting the unity from the smartphone itself. i still didn't do it but i made a good cleanup of all folder, even the system file and system folder, leaving jjust music photo and download...
- if everything works in recovery but not in the rom, it could be a kernel or a rom problem, so first change the kernel, if doesn't work make a clean install of something else ... i'm using MIUI v5 with marmite 8.7bigmem and for now everything started working again ...
Thanks

Here's what i Did. I did install Philz touch recovery. Its very useful. I also installed the Nexus Root Toolkit (NRT). Using NRT I launched the USBDeview. Using this i removed all the google related drivers from the system. I then restarted my phone is bootloader mode and restarted my system as well. Now my System was trying to install the nexus S drivers but unfortunately it said that the device in disconnected. But then in bootloader mode i put the phone in Mount USB storage mode and VOILA i was able to see all my files. I did take a quick back up . But still in the normal mode i was not getting the USB Storage prompt. Now i went back to the bootloader and did a factory reset. and then installed the Latest Avatar ROM. and now I am able to access the Phone storage through my computer.
I am not sure if i had deleted some files by mistake or some other issue. And thank for referring the Philz Touch Recovery. Its great.
Now am thinking of installing the Stock ROM for NEXUS S back on to my Phone. Do you think its a good Idea?
Thanks for all the help mate.

i don't think the stock rom is the best rom ... it depends on what you need ... by the way what is your data transfer rate ( into the SD )??? me in recovery get a good speed with a lot of spike, it transfer data at 5 mbs with spike of 15 and sometime go to 0 ... when i mount USB on the rom i get an almost constant 1.5 mbs that is reaaaaaaally slow ... if i test the write speed using the phone it returns me a normal speed...
p.s. when u say u mount USB in bootloader, u mean on recovery ?
I have a rooted S7 with TWRP recovery on it and i recently deleted my OS by accident as i was just trying to reset my phone to factory settings. Now the only thing i can do is boot into recovery mode and download mode, or i can just get stuck at a boot loop.
I have googled and googled and seen so many ways to try and fix this issue but nothing has worked for me. Heres a list of the issues i have and what i've tried so far. [Using Windows 10]
Installing Odin (3.12.3) and stock Samsung firmware from here.
Installing the necessary USB drivers from here.
My PC wont recognize my samsung device in either modes (recovery/download) and Odin wont recognize my phone either, as well as i cant find anything under "Device Manager".
Tried using ADB to transfer files to my S7 but when i activate ADB in recovery mode it just loads for a couple of seconds until it displays an error with no explanation.
I even tried downloading ADB drivers and necessary tools i got from this guide.
I also tried wiping Dalvik cache and cache.
I have tried three different USB cables on all available USB slots on my desktop PC and the one USB slot in my Surface and nothing works.
I have tried rooting previous phones but I'm still new to this rooting thing and there's a lot i don*t understand. Perhaps i downloaded the wrong USB drivers, or maybe I'm just unlucky. I just really need some help to understand how to fix this. If it can't be fixed is it possible to remove all traces of rooting on my phone?
The phone needs to be in Download Mode to use ODIN
The only sign it is connected is a COM port lit up at the top of the ODIN window
Add the .MD5 ROM to AP and hit start
Hello guys..
I really have a problem right now! I appreciate everyone who tries to help me. I´ll try to expain what exactly is my problem with my Mate8.
Also I´d like to apologize for mistakes of gramatics, because im acutally from Germany..
So, my phone was working right, and actually everything was okay. With time it got so slowly, because storage was full with datas and so on. I tried to clean up some things to get it again a bit faster and so on, but that did not make it (at all). Also windows wont recognize the phone anymore. When plug in the USB it didnt even asked for data, charging or photos.. also I had problems with charging, it took toooo long for a few %.
I was on "KANGVIP" Rom (as much I know i changed stock to this custom rom) https://forum.xda-developers.com/mate-8/development/rom-kangvip-slim-t3318572
Time passed untill 3 days I decided to flash a new rom normally, like put rom on sd card, wipe dalvic and cache, and so on. I wanted this rom; Lineage OS https://forum.xda-developers.com/mate-8/development/6-0-1-cyanogenmod-13-port-t3512985
But everything came up with different errors for different actions I did like this:
"cant mound sd card"
"cant mount inernal storage"
"cant mount data"
"cant format data"
"cant mount system"
"cant mount cache"
etc. etc...
I tried to change file system to EXT3. EXT4, EXT2, FAT, and so on, for Data and System. Nothing worked correctly (but I had still on some Filestystems instead of 0MB like 2700MB). Still not working correct... On TWRP.
Then I tried to update TWRP from 3.0.1 to 3.1 (new one released). Because I saw, more precisely, I heard that an update can fix this mount issues I had.
Said and done, I updated it and instead of 3.1 I had 3.0.2 (idk why but I didnt care). But still theese problems happend.
So then I saw in a Video on youtube (which I cant find anymore) that another recovery like CWM can fix this issues. So I downloaded CWM recovery.img and installed it with TWRP an rebooted to recovery again. And now I´m in a situation, in wich I dont know what to do.
Now the phone tries to start, but no OS installed.
Try to get into Recovery, but no recovery aviable exept eRecovery which is failing with data when trying to restore.
Problem is also that Fastboot and ADB is not working. Installed HiSuite, ADB drivers, Samsung drivers (though could help).
Tried Knife Italian, but no connection to pc..
Tried different cable, no luck.
Tried windows 7, 8.1, 10 Home and now im on Win 10 Pro 64x.
All I can do is to boot into Fastmode, but cant do anything. And when I try to boot the phone normally it stucks on "Your device is booting now..." because no OS...
PLEASE HELP ME GUYS! I REALLY NEED THAT PHONE :crying::crying::crying::crying::crying:
THANK YOU !!! :good:
Hallo,
If your phone is still recognized in fastboot mode, you can try following up my tutorial here » https://forum.xda-developers.com/mate-8/help/how-to-unbrick-l29-al10-stuck-fastboot-t3599775
I was experiencing the same problem. No OS, no recovery, no fastboot flash possibility, only fastboot booting. Keep in mind that you will need 15€ for this method to work but it is the only way to resurrect your device.
PM me if you need further assistance.

Thank you for the reply my friend.
The problem is, that it only boots in to fastbootmode, but any pc wont recognize it. I tried even with Mac...:crying:
Greetings
DC-Phoenix should recognize the fastboot brick state even if the device doesn't show up in Minimal ADB & Fastboot. Try my method and let me know if it works.
Hi guy's.
DC Phoenix save my mate 8 with factory firmware.
I was the same problem like you and search one week a solution and after I decided to pay and try Phoenix and now I write from my mate 8
Before buy 15€ of credit you can download and try to connect your phone on DC Phoenix
does the DC phoenix method take your phone to absolute stock? ie, stock firmware +recovery + Locked + no root?
Yes. You will have the factory firmware (stock) but with unlocked bootloader.
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.
