my tab pro 8.4 has been soft bricked, can anyone help me? - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

I'll start from the beginining.. Okay so since i bought my tab (3 months ago) i had a battery problem, but it wasnt a bad battery problem. Once it got to 95% battery it stopped charging. Anyway, about a week after that i was unhappy with the performace of touchwiz on my tab so i decided to root it and install the cyanogenmod 12 nightlies. I was happy with cm for a while but eventually i got bored of all the bugs and instabilities so i decided to switch to a touchwiz rom.. This touchwiz rom was a vast improvement from the stock touchwiz so i decided to keep it. However i still wanted to improve the performace so i researched online for apk's/zip's that could improve my tabs performace. I came across crossbreeder and people said it was really good so i decided to install crossbreeder through TWRP. Once installed i rebooted my device and i instantly found many more battery problems. For example my battery would go from 50% to 20% in 5 mins/my battery would run out and i would reboot it and it would have had 40% etc. I downloaded some battery calibrating apps and calibrated my tab. After all that, that battery wasnt so bad. It was still dodgy but no where near as bad as it was straight after installing crossbreeder. Anyway, this was about 1 month ago. Since then, no new problems had occured with the battery until last night. Last night, my battery ent don to 1% then turned off like it should. I put my tab on charge and rebooted however when it rebooted nothing would work. My touchscreen didnt work, my home button didnt work, none of the keys next to the home button didnt work. So i thought that this was no problem and i could just boot into TWRP, factory reset and install the backup that i made. When i tried this, i booted into TWRP successfully however i couldnt press any of the TWRP buttons, again, i thought that this could be solved by flashing the stock firmware through odin. I put my tab into download mode and connected it to my pc, then flashed the stock rom. Once finished it showed a 'pass' and i thought everything was sorted.. When my tab booted up, it again, didnt let me press anything and none of the buttons would work. This is when i panicked. I then went into the stock recovery to factory reset my tab to see if that would work however, when i went into stock recovery, i couldnt go up or down using the volume keys.. So my volume keys didnt work either. I next put my tab in download mode and connected it to my pc. I opened odin and checked the 'Nand erase all' box thinking this would fully reset my whole tab. I then researched the 'nand erase all' function to find that everyone said that it breakes your device and puts it in bootloop etc. After reading this i instantly disconnected the usb from my computer to my tab. I tried rebooting my tab to see if it still booted and it didnt.. (i waited 20 mins). I then ran odin with 'clear efs' box ticked on. Again it didnt boot. I went into stock recovery again to see if the volume keys would work.. they didnt.. Infact when i opened stock recovery it had 3 errors showing (which it didnt last time i opened stock recovery). They all started with 'failed to mount /data'. Now i am here.. Sorry it was such a long read, i thought it would be better if i explained in detail. Thanks to anyone that replies/helps me.

NAND Erase All shouldn't destroy your device. What you need to do is boot into recovery, and choose the Factory Reset/Wipe Data option. From there, reboot and you should be good! Otherwise if it doesn't boot, just flash in Odin again, reboot to recovery, and then Factory Reset/Wipe Data again. We'll get you back up and running in no time
The reason why you are getting those errors is because your data partition is NOT formatted (because NAND Erase All wipes out your partition details, so it looks unformatted), so the recovery and your kernel are not finding your data partition. Your device will be unable to boot without. Factory Reset will reformat your data partition and get everything into place. Let me know how it goes!

Device strange issue will not stop giving problems!

This is a list of events that I have gone through today. I received a new charger because the old one I had became defective & was charging my phone up & then it would go back down to 0% & then shut off & it would end up in a problem where the phone would not turn on unless I pulled out the battery while the AC was in & then it was able to charge but still it would turn on, on its own to drain the battery when off & this was very frustrating. The charger I have now works but the device acts strange over the last few months doing a task29 & flashing the first ROM after would make that ROM not work & then I had to flash a totally different ROM to make it work. I was using Android & it had died a few times & also I experienced the same thing I did when it would charge up & go back down to 0%. please read below:
I got my new charger today & at 62% of charge I decided to flash to a custom ROM via mem card again well the ROM was a success but when pulling battery out to restart it didnt want to work. So I went to flash again in bootloader by memory card it shut off on me in the middle & restarted into bootloader again & shut off again right away. I did a task29 it worked got it out of bootloader & now the orange led flashes off & on when its off & now ive gotten that to stop. What exactly is wrong with this device?
it was @ 73% and finally setup a ROM NRGY however it ended up shutting off on its self & going into a power boot loop constantly restarting until that ROM can no longer start & now its stuck on the boot screen w/ its info.
I flashed the stock SPL on USB now im going to try to flash the carriers ROM back.
Stock SPL = Successful!
2nd Touch Pro 2 ROM Version Flash = Successful!
Its working for now. Battery is @ 80%
AHH! After charging to 100% idk what it did but when I went into the other room to check out its all possessed.
I have a black screen w/ white text that says:
The device is unable to boot because either you have turned off the device incorrectly or tried to install an application from untrusted source.
Press Volume Up to reset your device or press any other button to cancel.
This operation will delete all your personal data and restore the device to its factory default settings.
IDK how this happened.
When I hit any key it didnt do anything it was stuck until I did a battery pull. Then I restarted the device it was stuck at the boot screen w/ its red info. It erased the entire ROM. Then I tried to do recover mode & it did nothing. I tried to flash the stock ROM again & no results & then again & still no results. I think its now not accepting the ROM at all since from: in the ROM update utility is blank.
Now it decides to get past the boot screen but then it malfunctions again & restarts itself & it tries to setup a 2nd time then after it does & its on sense home for a couple of mins it reboots twice & now its stuck on the boot screen again.
Things that I can think of.
- Isn't your batterie just broken? You will break your batteries when you deplete them completely. Maybe try a new batterie, because you said that you let it die for a few times. It could be that this is causing your problems.
- Did you flash true usb when you were in the bootloader? Give that a try, because I believe that the customruu performs some sort of checks. Maybe this is nonsens, but you can try it.
The battery was fully charged & it was working better than before.
I reflashed the Stock SPL to flash the carriers ROM back & that worked but at anytime it just rebooted for whatever reason to make it so the ROM was unusable at any time I would reboot it would decide to actually go past it seldom. I experienced that at one point oddly it went into setup n it did it again after a while its just acting strange.
If you're back to stock SPL and stock ROM, can't you just send it back for a warranty replacement ?
IDK how old it is. I bought it brand new from ebay.

No warranty bro...
You can try but no warranty 9/10 times.
What ROM are you using? I used to have that issue with my betas.
It wld destroy itself after softreset and I would have to reflash.
Try to flash, turn off right after it boots, turn on and see how that works for ya.
Rep had told me I could get it replaced & they know I bought from ebay. But I havent called them on this yet.
It doesnt work. It usually doesnt go past the boot screen. Flashing does nothing to help it. Whenever it feels like it it may have to stay on for a few mins to go into setup but most of the time it will stay there & reboot, reboot, reboot, reboot each time its a different # of times & it will reset itself at anytime. Ive even had bootloader shut off on me & restart itself during flashing its a pain. I had another issue I didnt mention my device on any custom ROM when I had 0.85 olinex SPL the device would just freeze & not respond every time. Now this is a different situation. I am back of SPL 0.87 which is the default. I flashed the entire carrier ROM which 0.79 was rewritten w/ 0.87 & that was successful but its still rebooting & causing fatal problems including the black screen w/ white text.
UPDATE: I just walked into the kitchen. Somehow the device turned on by itself & now its sitting on the sense home screen. I know its not fixed but idk why it would turn itself on.
Moved as not ROM Development.
Try flashing task 29 1st... Might be because when you flash remnants of the older OS are still there causing trouble. Remember though, you need to have Hard SPLed it 1st....
I got so frustrated I just got done calling T-Mobile Tech Support & they are going to ship me a replacement.

I thought I would reply to you.
This is what started my problems is when I did a task 29 my device was acting funny afterwards. I did it again about a month later cuz I flashed way too much & it kept getting worse. But Task29 didnt help this time its what caused me to have to flash 2 different ROMs cuz the first one I flash after doesnt work.
I received the battery & it didnt do anything.
I'm still waiting on the replacement to come.

[Q] Touch Panel - Fail / Sluggish Performance

Hey all, first time poster. I wrote a real nice explanation of my problem, but i lost it so anyways, i'll keep it short(ish).
The EVO is less than 3 weeks old, running the latest OTA, recently rooted using UnrEVOked 3, nothing fancy. I ran the battery down completely last night (first time since i got the phone) and once i got to a power source, it wouldn't boot correctly. It hangs at the white splash screen, and then finally boots up but won't respond to any touch input.
Also the phone seems to be running exceedingly slow, the boot process takes substantially long than normal once it gets past the splash screen and my live background is freezing and seems to be stuttering.
I launched into the bootloader and i get a "Touch Panel - Fail". LAME!
I'm not sure what to do at this point, whether i should wipe it or go back to stock or what. Any advice would be much appreciated.
UPDATE:
I managed to get the phone into the recovery console, make a back up (i was planning on going back to the stock image) and wipe the dalvik cache and fix permissions. I rebooted and voila! fixed. Hopes this helps any one else who has this problem.
Moral of this story: Travel with a charger.
Another update. It froze up again in the middle of sending a text. I rebooted by battery removal, and it did the same thing again. Super long splash screen and sluggish boot up, no touch response when it finally came up. I booted into recovery and cleared the dalvik cache again. Seems to be working again now. We'll see if it does it again.....
Well, the screen locked up again. I tried going through the whole process again. I wiped the caches and battery stats, nothing. I wiped all the storage and data, booted into a clean stock interface, nothing. Restored the backup image, and then at some point, through all the rebooting and whatnot, it just shut down completely. I can't even get it to the bootloader. I'm really feeling like it's a hardware problem, and i've made peace with sending it back for TEP, but i have no way to unroot it.
Any suggestions? Please......
Theres unroot processes out there. I cant remember where but ive seen them. Mine gets sluggish too, but after a reboot its ok. You cant even get into the bootloader tho. I'm not even close to an expert but.......uh I'd 'lose' it and call the insurance co....

Galaxy nexus keeps rebooting

I have a stock GN, not rooted yet. Today my phone automatically shut off and now it starts back up, google logo shows up and all those colors come on for couple of seconds and then the phone reboots itself.
I can press both volume up+volume down + power button and get into a menu which gives me the options of Start, Restart bootloader, recovery mode, and power off. I choose recovery mode but then it goes on to an android sign with exclamation mark. After that I can't seem to get anywhere. I have tried volume up +power, volume down+power, and volume up+down+power but nothing seems to work. It just keeps on rebooting it self.
Any solutions to this problem??
There are two possibilities:
1) Software problem. Since you were stock, this is unlikely.
2) Hardware problem. This is more likely, in my opinion.
If you want to eliminate 1) as a possibility, you can try this:
1. Download the GNex Toolkit here
2. Install it & get the drivers working on your computer (if you haven't already)
3. Unlock the bootloader by selecting Option 3 (it'll wipe your phone)
4. Flash factory stock rom by selecting option 8
5. Try it. If it works, congratulations. (if you want to re-lock your bootloader, use option 11)
If this doesn't work, relock your bootloader and send it in for warrantee. (most likely a hardware problem)

So, I did the above method and after flashing the factory stock rom it won't start up anymore. It doesn't respond to anything at all. It seems I've bricked it
Is there any way to unrbick it now? I'm assuming I can't send it in for warranty either now if it's semi bricked. Unless it's been completely bricked which means there is still a chance of getting a replacement phone.
I have the same prob on rooted SGN
This morning I switched off the airplane mode to be available, system crashed and restarted. And then still the same again - booting / android logo / restart again.. /./. I am using Android Revolution HD 2.1.5, for last month with no problems.
I tried to boot into recovery, then wipe the cache and reflash rom and radio from sd, it is still the same. I can see all the files on my int. sd with no probs.
Please help.
I'm thinking it might be a hardware issue, but I'll wait for another member's opinion before confirming.
Solved!!!
That's what I thought - HW prob, but it seems that luck is on my side, I hope. It helped to get back on stock but with total deletion including int partition
Anyway thanks for support.

Was your phone rooted or bootloader unlocked before the problem occurred?
Anyways I've sent in my phone for warranty, hopefully samsung will fix it.
So my phone company called me today and apparently Samsung told them that it's corrosion(?) problem. When I asked exactly what does that mean they said it's moisture damage or physical damage that probably caused it. But I'm confused how could my phone possibly get moisture damage inside an otter box. I know how delegate these devices are and I know how to take care of them.
Anyhow it'll be $90 to fix it. I had no other option so I asked them to go ahead with the repairs. So frustrated with Samsung to be honest. I never dropped my phone once, never had any water damage, phone was always inside the defender case. And I still have to pay them for fixing my phone even though it's not my fault.
That's quite worrying, I just started having boot loop problems today. I've had the phone since Feb 29th and not had a problem with it yet, but today it started boot looping. I went into recovery and did a factory reset, was alright for a couple of hours then it crashed, started bootlooping again. Running stock 4.0.2 unrooted, I'm wondering if flashing 4.0.4 might help.
I'm in the same boat.... unrooting stock 4.0.1 firmware - canadian version from Negri.
April 23rd my phone crashed and started boot looping. Google logo - reboot - Google logo - reboot
Factory reset worked. I installed less apps than I had before figuring perhaps an app was corrupting something.
Yesterday - it happened again. Phone crashed. Boot loop. Factory Reset worked. Installed even fewer apps.
We'll see what happens this time around. I am hoping it is just a software thing. Hoping 4.0.4 gets pushed soon too.....
I've been having the same issue, plus sometimes my home screen it would lock up and wouldn't let me do anything, so I did a battery pull and it would boot loop for a half hour.
After the 3rd time I just took it to my Verizon wireless store, and showed them the situation and they couldn't figure it out, so their sending me a replacement, which I'm not looking forward too, don't want a semi-used phone....
Via Galaxy Nexus [LTE]
Rebooting Issue Solved.
I was also a troubled Samsung Galaxy Nexus user and my phone kept restarting more than half a dozen times everyday. Most of the times when I switched between two or more applications, or when it was simply idle on my desk.
However, I found a solution (at least in my case). All I did was root my phone, install cwm recovery, and flash a custom rom after wiping cache and factory resetting the phone, It's been about 5 to 6 hours now since I flashed the custom rom and I haven't had a single reboot or hang since.
Others who face this problem, please give it a shot, who knows? You might save your Galaxy Nexus instead of sending it back to get a replacement or spend some money on it for repairs which aren't even required in the first place.
I also had this problem unrooted. I had to give it to Samsung for the warranty
Swyped on my Galaxy Nexus running AOKP with Trinity Kernel, overclocked to 1.4GHz
I got my nexus yesterday, almost immediately after first start it start to install JB from OTA.
I did buy 2000mAh samsung original battery and started straight with it. not even testing with 1750mAh bat.
after installing JB and needed softwares, it started to randomly reboot.
it rebooted even it was just in my pocket.
sometimes when I did do something, display freezed and after about 5sec it rebooted.
Now I did changed to original 1750mAh, and it havent boot at all couple hours, even I did play angrybirds space.
I wont dare to root it before I am very sure problem is with 2000mah battery.

I could be wrong, but have you tried to clean the pin on the battery? Seems like battery and the phone isn't contracting too well
Swyped on my Galaxy Nexus running AOKP with Franco Kernel, overclocked to 1.4GHz
Little update, phone did continue rebooting with original 1750mAh battery also.
I did also reset with recovery mode, and after that it did also reboot one time.
like it uses all memory/cpu and when nothing to do reboot (like windows )
I also did flash stock rom with toolkit but no help.
I will test rooting phone and flash another rom, or is it useless ?
after using couple days, not yet rooted.
Phone works and wont reboot even in heavy stress. but sometimes it just reboots by own not a single program in task list.
might reboot right after previous reboot or take hours to reboot.
stupid phone
I have been done some research.
I did one more time reflash google stock with rootkit, and forgot lock phone, it was almost 3 hours by own in wifi, no reboots at all.
when I noticed that I forgot to lock it I rooted whole phone and installed paranoid android 2.13 with CWM.
Now Ive been using 2 hours without any reboot, installing software, setting things up and using apps.
I dont understand at all:silly:
edit: noup, yesterday evening one almost reboot, paranoid android did reset itself but didnt even reset uptime. so I didnt count that normal reboot.
but after wake up this morning, it did reboot once when I put in my pocket, another just lying on table, once activating bluetooth in my car.
going to send it back to seller.
I have a similar issue, although not quite the same. Last night my phone started boot looping - it managed to boot up to the lock screen, and I can use it for about a minute before it dies and then reboots. This continues again and again (I have to pull the battery to quit it).
I have stock JB on my GSM GN, but rooted with an unlocked bootloader / CWM. I restored my old CWM backup, and had the same issue. I also wiped the cache and the dalvik just to see if that helped, but I had the same issue. I then tried to do a factory reset in CWM, but after I did that the boot loop just got to the nexus logo and died, entering a new (slightly shorter) boot loop. I went back into recovery and reflashed my CWM backup, and that at least got me back to booting into android.
I can't understand what's going on - could it be a hardware issue if it will happily stay alive in recovery, but dies after 1-2mins of android?
Thanks for your help. If it is hardware then I hope I can reflash the stock recovery / bootloader and unroot through recovery... the phone doesn't stay on long enough to do it when it's booted into full android!

[Q] Phone turns off automatically

I run a rooted SG S3 on stock 4.1.1 with an old 3.0.56 kt747 kernel
Until recently, I've been running this set up for years without any problems.
I've also updated fairly recent CWM along with the latest SU.
As the title states, my phone has been turning off automatically. After weeks of troubleshooting, I noticed a pattern.
When I press the power button, there are three different scenarios that happen.
The phone goes to sleep normally
The phone goes to sleep and immediately wakes up to the lock screen
The phone displays the shut off menu
If scenario 1 occurs, everything is fine and runs perfectly for an indefinite amount of time until i attempt to put the phone to sleep again.
but, if scenario 2 or 3 occurs, the phone automatically shuts down abruptly, within 1-5 seconds.
This problem still occurs even when I boot into safe mode, and I have eliminated the SD card as a suspect. Furthermore, booting the phone up has become extremely difficult. The boot would sometimes crash after the samsung logo, after the splash screen, or during the boot animation. It takes somewhere around 3-5 tries to fully boot up the phone.
Booting into CWM recovery is still possible, but even that sometimes crashes mid-way. I've also noticed that at certain times, when I click the power button to select an action in CWM, it actually double clicks (thankfully CWM is tolerant to that) and cancels the action I was trying to do. I've done some googling and found that an over sensitive power button is a common occurrence in this model, and while that may explain why the 3 different power button scenarios occur, it still doesn't explain the crash.
Finally, I seemed to have remedied the automatic shut off problem several times by wiping cache from CWM. When I first started having these problems and began troubleshooting, wiping the cache eliminated the problem for about a week before the problem came back. When it did, I uninstalled some apps and re-wiped the cache which eliminated the problem again for several days. However, these periods become shorter and shorter, and now wiping cache does not seem to help at all. I've also tried wiping the delvik cache, but it didn't help.
I'm stumped right now. Any suggestions would be appreciated before I try some more large-scale attempts such as resetting my phone or taking it apart. Thanks everyone!
This definitely fits more in your large-scale attempts category, but it is what I'd try.
I'd grab the stock 4.1.1 firmware from sammobile.com and Odin back to stock. You're fortunate to be on the old firmware, so you can Odin back to stock. When Odin completes successfully, pull battery don't let the phone reboot normally (untick auto reboot in Odin). Boot straight into the stock recovery and do a full wipe. Then reboot your phone normally.
Doing this will correct any problems that exist with your internal storage to the extent possible. If you've still got problems after doing this, it is probably a hardware issue.

Yeah, that's part of the reason why i didn't want to upgrade the bootloader for the newer firmwares. I messed around with my phone this morning and its been avoiding the problem ever since. Not exactly sure what I did though lol. Thanks for the reply, I'll try it if the problem comes back over the next few days.
Your phone isn't "crashing," your power button is malfunctioning. The fix is pretty easy. You will need to open your phone up and scrape it off (the phone can be turned on without it). There are youtube videos that show how to remove it.

Samsung Galaxy Tab S stuck in bootloop after flashing official ROM and factory reset.

After recovering from a previous bootloop issue with my Tab S, I'm in the same situation after flashing the official Samsung stock ROM for KitKat 4.4.2 via Odin.
When the ROM was first flashed, the tablet began working as per normal with the exception of it taking 10+ minutes to fully reboot and the device somehow restarting itself and loading the display within a second. However, after a few days, I kept receiving pop-up windows on the tablet stating that different applications (most of them I didn't have opened or running in the background at the time) weren't responding. A couple of days after that, more of said pop-up windows kept appearing on the screen, sometimes freezing the whole device until a push notification appeared in the background or the device force-rebooted itself.
I flashed the ROM again once or twice and cleared the cache partition to see if that made any difference, which it unfortunately didn't. I also removed the microSD card and SIM card, force-rebooting the device without them, and then with them when that test failed.
Now, for roughly about a week, the tablet has been stuck in a bootloop (the splash screen animation) where I have left it to drain the battery, leave it for about a day or so, and recharged it to 100%. So far there hasn't been any success.
Today I finally factory reset it to see if that may help, and the only thing that has changed is that the sound of the device rebooting is now playing when it does transition to the loading screen, which I had turned off previously when the tablet was still working.
Is there anything else that I may have missed that could help it work again? It's not rooted (and I would very much prefer to keep it that way) and has not had a custom ROM installed or flashed onto it. It can still enter Download Mode and Recovery Mode, but other than that and being about to use the Power-Volume Down technique, there's not much else I can do with it so far.

Factory reset, install stock firmware, wait ten minutes and you should be good.
But why kitkat? MM is available and working well.

It worked! Thank you so very much!
And I'm not a huge fan of updating my Android devices due to past experiences, but if this happens again, I might just update it to Marshmallow.

i love you man...this worked for me too...thank you...now i need to reinstall TWRP again and see what's cooking......
I had this problem recently too, with the added complexity that the "Factory Reset" option in recovery wasn't working -- it would say something like "MDM does not allow factory reset" and then just reboot.
Fixed it by directly flashing TWRP with heimdall, then booting into the new TWRP recovery, performing a factory reset, and then rebooting the OS. This time it got pass the bootloop.
i flashed new twrp for T700 it's bootloop cannot enter the twrp menu keep bootlooping ...what's the solution for this?please help
Help ME!
What are "stock firmware" and "MM"? and where to get it?
I've replaced the power button thinking it was a hardware issue but now I'm not sure. I've also installed a few different stock roms but still have the same problem. Does anyone have any insight as to what could be going wrong and what I can try to get it fixed? Thanks for any help you can give. The device is a Samsung SM T-800
