Bricked EVO?

So this was sort of a 3 part process that I need to detail to see if anyone has any clues on how to help. I tried to search the forums but had no luck coming across anything. Basically here is what I did, as I'm using a Mac I took a back door route.
1. Rooted phone using UnRevoked3. This worked fine I was using it for a day or two but then wanted to install Cyanogenmod so I could use Froyo. I wasn't able to install and it appeared the consensus was that the way unrEVOked works does not allow the proper access to install cyanogenmod. According to theunlockr.com/2010/07/20/how-to-root-the-htc-evo-4g-unrevoked-method/ it appeared that after installing unrevoked one still needed to unlock the NAND as seen here theunlockr.com/2010/07/20/how-to-unlock-nand-on-the-htc-evo-4g/
2. As this process did not work on Mac I scoured the forums and found this process forum.xda-developers.com/showthread.php?t=705113 and went through all the steps. Everything worked fine until the end when I installed the Radio an then the ROM (this was backwards from their instructions, ROM then radio which may have cause the problem). Regardless I ran Radio update, but then didn't reboot and installed Cyanogenmod update linked to from here forum.xda-developers.com/showthread.php?t=729367&highlight=brick
3. Everything appeared to work fine. After installing Cyanogenmod it asked if I wanted to reboot. I said yes, it said updating radio then rebooted. This may have been where I made the true mistake. It gave me a thing with an exclamation point after rebooting. At this point I waited for a little while then tried restarting, I took the battery out and tried to press a button. After this it wouldn't turn on. Am I totally screwed? My guess is that I probably am and feel like a total moron... Please let me know if there is anything worth doing...
Thanks,

Permanently Bricked? Help!

I am running the leaked T-mobile froyo rom on my defy.
Today i found my phone not responding. it was stuck in the motorola logo for a very long time and did not load any further.
I decided to reflash my phone with the SBF again to see if i could just start over.
However, when i try flashing the phone, i get stuck at the "erasing flash memory" step.
Is there a hardware problem on my phone? I guessing there may be something wrong with my internal flash memory. Any suggestions?
Thanks!

Here is my solutions, (no guarantee if it dont work or do damage the phone)
Enter the bootloader and re-flash it with RSD lite. Sometimes it will fail when flashing the Code Group 37, ignore it and restart the phone in to bootloader and flash again.

get into recovery mode full wipe

make sure you have the latest version of RSDlite too

Thanks for the replies!
Ok, so i've tried to reflash the sbf several times with the latest rsd lite (4.9) with no luck. The progress gets stuck at "erasing flash memory" and eventually i get a Fail message.
Unfortunately, I cannot access the recovery mode anymore, because i get a "corrupt code" error now due to the failed flashing attempts.
Also, my battery is low now, and it seems like i cannot charge the battery without a firmware. I'm trying to find an alternative way to charge my battery.
If anyone has any other ideas; I would much appreciate it!
Thanks again!

I can't see how it won't reflash?
If it's in bootloader (power & Vol up) then you select the .sbf file it should work?
I didn't realize that it checked the version on your phone?
A little out of the way method to charge your phone.
http://forum.xda-developers.com/showthread.php?t=892026

use the method above to charge your battery and use a linux live cd or boot linux if you have it installed, download a file called sbf_flash and the sbf, copy both to your home directory. Throw up Terminal and run:
sudo chmod +x sbf_flash
sudo ./sbf_flash blahblahblah.sbf
Thats it your done! I don't use RSD anymore because it refuses to work anymore for some reason. The linux method always works for me. Obviously replace blahblahblah.sbf with the correct sbf file name

This will sound nuts as well, but also try flashing on another pc with rsd lite installed.
I couldnt get rsd lite to work on my main pc, (kept getting a flashing failed message).
I installed it on a laptop and it worked fine, the first time.

Thanks for all the suggestions! i'm going to try this once i get home from work.
I feel practically naked without my phone, can't even focus.
I'm really hoping there isnt any hardware problem. Prior to my phone locking up, i noticed several times my CPU usage increased to 100% and would not go back down. I checked my task manager, but couldnt find any apps or services utilizing the CPU to that extent. I had restart my phone to reset the CPU usage.

It could have been a dodgey application.
Was your phone rooted prior to you attempting to flash it?
If so, how did you root? Did you install any custom recoverys?

i dont have any custom recoveries and i rooted with superoneclick

I used the cut USB cable method to power my phone back up. (Thanks!)
I have tried flashing with a different version of RSD lite as well as flashing from a different machine with no luck.
It looks like I'll have to try flashing from linux. I'm not very familiar with the linux environment. Is there a more detailed guide to doing this through linux?
I found a Ubuntu 8.0 CD lying around. I'm hoping to use this.
Thanks again!

zyxwvut, I tried out your method of flashing my phone through linux.
I used ubuntu 8.0 (booted from CD... didn't install anything)
Unfortunately, it didn't help. I'm still getting a flash memory erasing related error.
I have included the error message below:
--------------------------------------------
>> waiting for phone: Connected.
>> uploading RDL03: 100.0%

--------------------------------------------
Sorry to be a pain, but does anyone have any other ideas? Is there a way to manually erase my flash memory? Thanks a ton to everyone for your help so far.

Try to take out battery for 15 minutes. Use this time to download another stock rom (maybe a later release than your old one -> downgradeable). Maybe your downloaded file is broken.
Got stuck in different stages flashing my phone and many times I thought it was finally bricked; but I always could recover it somehow.
Good luck!

Thanks for the suggestion.
I have tried several different roms; even just bootloaders with no luck.
I believe the sbf i am using now is fine because i have successfully flashed this exact file just a month ago.

What's the last ROM it works? flash that sbf may help

The last rom that I flashed that worked was the leaked froyo US T-mobile rom. It is also the rom I have been trying to flash with no luck. =/

hmmmmm. Strange...... I have had several failed flashes. Upon reboot It's gone straight to bootloader with "code corrupt" message.... sbf_flash always seems to work! I say be persistent and keep trying? Maybe you've gone and FUBAR'd your phone..... That sux though! Let us all know if you get it going and how you did it.
On a side not... The leaked froyo from US t-mobile is system version 34.4.9, the exact same version that they just released and made and OFFICIAL rom.... Maybe a warranty replacement is in line for you. If you were on the leaked US froyo, which is official now, and your phone doesnt get past bootloader, maybe they can't tell what you've done to it

Here is the easy solution but need time and minimum $5 charge..
Just sent to Motorola with RMA. (Depends on your warranty, but mine was free except USPS flat rate box.)
Then they send back with froyo version of defy!
I sent mine with same brick issue 2 weeks ago - I installed 2.2 from other countries and rooted and rolled back 2.1, then I got froyo version of defy today.
I have 34.4.9.MB525.T-mobile.en.US (2.2.1) now.
You don't need to tell them too much, I think. Just say, Hang, not boot up.

I read somewhere that sbf_flash will not work properly on linux kernels below 2.6.30
I believe that Ubuntu 8.0 uses 2.6.24 kernel ( I could be wrong about that though )
Try using a newer linux distro with kernel 2.6.30 or above.... I'm thinking that this might work for you!
Also, I think that possibly trying an entirely different distro could help not that Ubuntu isn't capable but maybe theres a weird bug or something. I use Linux Mint live session
Let us know
Sending it back for warranty is the easy way
out LOL! Solving this could help a lot of people in the future

[Q] Root66 T999UVDM5 ROM

I have been on all the Root66 versions, and have had no problems ever...... till this UVDM5
I made a CWM backup (2 just to be sure) and proceeded to flash this new version that I have been waiting for so anxiously!
After it booted up, my desktop was the same, and all the apps showed, but talkback was already turned on, and I could no way get to the settings to turn that #$%%$ thing off. Heck, I could not even get to anything at all. It kept talking and reciting numbers everytime I tried to do anything. It was "Frozen" on the main homescreen, and could not do anything. I sometimes could get to the app drawer and that, too, would not scroll or do anything. I Re-flashed the thing after doing another download with the usual cache, dalvic blow out, and it acted the same way...
I decided to revert to the backup and tried to get to recovery (CWM).... That, too was gone! Stock recovery. I flashed the only version I had of CWM and it booted, and declared both of my backups were "corrupt" after it was almost done restoring?????? WTF!!!
I then reloaded UVDMD5 again, got the same results so did a factory restore and got to install my ROM manager, and re-flashed CWM to the version it uses, and tried the restore.....
It worked, and now after some pressure packed moments, I'm back to the UVLJA. I have to go on a trip tomorrow, (in a few hours) and need the phone working. PHEW! if anyone knows why the hiccup that I had occurred, please chime in and let me know. I still want the new OS and after my return, I plan to do the update again.... Hopefully....... Just gotta ccalm m my nnnneerves a bit before I attempt it again!

It seems to be an issue with the latest version of TalkBack on most roms. I had the issue already and from what I read in the forums, many other people have to. My advice, as soon as you flash a rom, uninstall or freeze talkback and DO NOT let it update to the latest version. Im not too sure what the issue is but hope Google fixes that soon.
I think also that I had a problem before when I installed the stock 4.1.2, it seemed to take my sdcard and renamed it to 0 on the sdcard. Took me a few hours to figure that out. I then copied everything that was in the folder 0 over everything in the root of the sdcard and it was back to normal.

Thanks! (Clicked it already)
I did notice a LOT of stuff was on the external card after the final recovery to the older version and had to clean up the external SD card.
You were right! I had no means to freeze the TalkBack, or do anything at all while within the OS itself, so no alternative was available to me at that time except a Factory Restore. The re-installation of my software was just going to take too long, so I did a recovery using the same version of CWM and was back where I was before the fiasco. Good thing I got it going.... Ida been really screwed! LOL. I'll try again maybe later, when I get home.
When I do try again, I'll remove the SD Card and then do the install using a spare one.
Have a great day!

Help - Galaxy Tab S 10.5 Bootloop Out of Nowhere

So...
Last week, my wife's Tab S went into a bootloop. She runs complete stock, we haven't rooted, or anything. There had been a notification about an update, but she hadn't touched it. She'd updated to Lollipop at some point last year, but hadn't applied the absolute latest update. One day last week, she just turned it on, and it started bootlooping.
Because it was so stock, there were no backups, no nandroids, or anything like that. No Custom Recovery. I told her "well, we can just do a factory reset. You'll lose everything, but once we get you back up and running, it'll just re-download everything from the Goog." So we factory reset it. Looked good for a minute, booted into the first screen, enter in your Wi-Fi password, all that. As soon as we got the Wi-Fi password entered, however, it re-booted. And keep rebooting. Bootloop city. No problem. I walked her through (over the phone) using Odin to flash the latest Lollipop firmware. No dice. It appeared to flash successfully, but still bootlooped.
Over the weekend, I tried using Kies to flash the most official firmware I could find. Everything was successful -computer recognized the device, was able to download "direct from the source," as it were, but it got stuck at 69% twice before failing. I read somewhere that one had to run Kies in administrator mode to get it to successfully complete. So I did, and it got past 69%, successfully completing the flash. STILL NO LUCK. STILL WITH THE BOOTLOOPS.
Last night, I realized that I hadn't flashed in Odin using Administrator Mode. Tried it, using latest 5.0.2 (XAR-Cellular South). Flashed successfully, all appeared well. Still bootlooped.
So, I'm stuck. I can get into recovery, I can get into Download Mode, I can successfully flash. I just can't get the darn thing booted.
Thoughts, anyone? Should I try flashing a Custom ROM? How hard is that using Odin? Thanks in advance.

Ok this will take a few tries but here is my method of dealing with this situation
1) Flash stock using Odin
2) AS SOON AS the screen goes blank, start holding Power+Volume Up+Home
3) When recovery boots, release the buttons
4) Use the volume buttons to select "Wipe data/factory reset"
5) Press power to confirm
6) Reboot
If that doesn't work, you may either:
1) (more likely) Installing a ROM will fix the problem
2) (unlikely but possible) You might have worn NAND pages, which I doubt but could cause this behavior.

Thanks, I'll try these steps tonight when I get home, and report back!

All right, here's something interesting. Before I tried your first step, I remembered that the other night, I left it stuck at the Samsung logo -it was just kind of stuck there, and since the behavior was a little different than I'd seen before (not continuous bootlooping), I thought I'd boot into recovery and wipe. I did, I wiped (factory reset), and rebooted. The tablet booted into the first screen, Accessibility/Wi-Fi, blahblah. This was where it usually rebooted. On a hunch, I bypassed entering in my WiFi key. I then bypassed almost everything else (Samsung account, Google account, etc.), expecting that the tablet would reboot at any moment. But I made it to the front apps page, where it shows you the side-launcher, the Magazine-Flipboard thingie, and whatnot. Wi-Fi still not connected, though. I opened up the app drawer, and scrolled around. Looked really good for a moment. I even took a picture with the camera, and viewed it in Gallery! Feeling brave, I thought, "well, maybe it just needed a couple of minutes before firing up the radio." So I went into settings, and inputted my WiFi key. It connected. And rebooted into its bootloop. (getting so tired of that boot-sound).
Went ahead and flashed the most original stock firmware I could find. As always, flashed successfully. As soon as it booted, I made my way to recovery, and wiped, per your instructions. No luck. Bootloop again.
It's something in the WiFi is what I've come to think as a result of the above. Which I don't entirely understand, as I thought the radio got re-flashed with the firmware.
I'm ready to try flashing a Custom Rom. Can I do that through Odin, or should I try and flash TWRP, and do it through there? Will TWRP flash without a working (bootable) OS?
All right. Thanks for your response!

Try this as a test.
First make a full backup of every partition with twrp including the EFS <<IMPORTANT!
Get it booting again without wifi then root the device and delete the EFS folder or delete it in recovery.
Reboot the device and try and enable wifi.

Got TWRP installed. Won't backup. Fails at 16% (system partition, I think). Just powers down to battery indicator in the middle of the backup. Looks like it backs up the EFS, though, since it's the first one. And when I go into TWRP's Restore option, there's a backup there (though I don't dare try and restore it).
Now I have to figure out a way to get the Custom ROM and GAPPS I downloaded onto the tablet without a reliable boot... It's gotten to the front screen a time or two tonight, but starts looping even when I bypass the WiFi setup.

Entered adb/TWRP interface. Tried to push two files, a Custom ROM file, and a GAPPS file. The ROM failed, with some sort of "Error 7," incompatible data, blahblah... Just out of curiosity, I tried to push the GAPPS file, and that failed after about 6%, and the tablet powered off.
I'm running out of ideas.

copied a custom rom to a USB/OTG stick (thumbdrive), and plugged it in. Fired up TWRP, tried to install. Wouldn't. Wouldn't install GAPPS, either. Looks like the only way it wants to flash anything is through ODIN or KIES.

The Latest...
All right...
I remembered that sometimes the TWRP version mattered. When I installed TRWP last night, I installed the latest and greatest, 3.0.2. Last night after I gave up, I remembered that sometimes, the latest and greatest TWRP doesn't install things perfectly. So, this morning, I downloaded TWRP 2.8.6-ish onto the USB/OTG device, and re-flashed the recovery partition. To be honest, I was surprised that TWRP was even able to flash that (but the TWRP image is only like 9.8 MB, so...)...
Got TWRP 2.8.6.0 flashed, and rebooted into TWRP. Immediately decided to try and re-flash the custom ROM that I'd tried unsuccessfully to flash last night, since the thumbdrive was still plugged in. Resurrection Remix Lollipop. Lined up GAPPS in the queue, as well. The ROM *appeared* to flash better than it had in TWRP 3.0.2, but it was sort of hard to see... GAPPS failed, and I was prepared to watch another round of bootloops. It did bootloop, sort of. The RR splash screen appeared, said that it was installing (or preparing) xx out of XX apps. Then, it rebooted. I figured it was doing its bootloop thing. However, it got to the same screen, "installing xx out of XX apps. Except that XX number had gone down, and the xx number had gone up. It repeated this action about 4 times --the last time I saw it reboot, it was "installing 1 out of 2 apps." And then...?
It booted into the RR lockscreen.
Of course, there were no GAPPS. In fact, there are something like only 20 apps total on the tablet. But it appears somewhat stable at the moment. (See picture).
Afraid to try and connect WiFi, afraid that it'll just bootloop.
Speaking of bootloop. At one point, once we got it booted, my wife hit an option in the Settings. LCD Density, I believe. As soon as she hit it (she literally just placed her finger over the 320 default option), the tablet rebooted. No loop, though. Rebooted straight back to the RR lockscreen.
So I appear to have a somewhat stable OS flashed onto the tablet at the moment. No GAPPS, though. No WiFi.
Anybody have a suggestion on where to go from here? I have my doubts as to whether or not I can even back up this configuration.
Sorry about all the updates. I kind of figured that if *anyone* else ever goes through what I'm going through, they'll have some sense of all the different things that can be tried in resurrecting a bricked/bootlooping device. I appreciate everyone's efforts to date -thank you so much, @Lightn1ng and @ashyx.

All right, because I can't leave well enough alone....
I got WiFi up and working. Tablet still stable and working. Wheeeee.... No GAPPS, though.
Downloaded GAPPS, second-smallest package from opengapps- only 128M (5.1 ARM package). Downloaded it in Android, from the tablet! Tried to flash it in TWRP. Failed, tablet rebooted halfway (not even) through. Now it's bootlooping again...
I should've left well enough alone, and waited for someone. Have tried re-installing Resurrection Remix, but tablet keeps failing to flash. Might have to try and flash a different TWRP. I don't know...

Have you tried another Gapps? Also, is this the WiFi only model or the LTE model we're talking about?

It's the WiFi-only model - SM-T800.
It's kind of weird. I thought it might be some sort of internal memory problem (like the worn Nand pages you mentioned), since almost anything I try to do in TWRP fails (although I was able to flash an entire Custom ROM the one time AND get it booted) -but backing up isn't working, whether it's to internal/external SD. And the fact that I can flash perfectly (subjective term there) well using Odin or Kies tells me that whatever problems the tablet is having, something's getting through.
I'll try a different GAPPS package. Right now, though, TWRP isn't letting me flash hardly anything, and moving files back and forth on this thing is just awful.
AGH - I was so close!

Maybe somebody else with a T800 could backup their entire EMMC using
Code:
dd if=/dev/mmcblk0 of=/sdcard/full_nand_dump.bin
And you take the file on your tablet and do
Code:
dd if=/sdcard/full_nand_dump.bin of=/dev/mmcblk0
And restore YOUR efs folder using TWRP.
THIS IS A DANGEROUS OPERATION AND I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!

@ashyx Any more ideas before I go ahead with my evil world domination plan to recover this device?

I wouldnt carry out any risky operations until a full backup can be made with twrp or you may end up with an unrecoverable device.
If twrp cannot backup the system partition then there is an issue with the partition.
Try backup again and post the recovery log, it may contain some relative information.

I have the same issues and have tried eveything. I was rooted and running the latest Pheonix rom on my sm-t800. Last Wednesday (8-10) I starting getting boot loops out of nowhere, no new apps nothing just a daily driver. I've been through everything on here and have gone back to bone stock but to no avail, the boot loops just keep coming. I can connect to wifi and get things set up but if I try to use anything more than 'light usage' the tab starts its boot loops again and rows fits for about 10 minutes and always different timing on the boot. Sometimes it will make it to the Samsung logo, sometime only to Tab S and sometimes about 10 seconds of usage.. I know this isn't helping much but wanted to let you know there are more of us with the same problem. Will be blab to try anything to help said issue.

Exactly the same issue on my LTE version.
Samsung support just asked me 230€ for a new motherboard.
I refused to repair. I think it is related to nand memory..

Hello I have both the 8.4" and 10.5" I updated the 8.4" to Android 5.02 nothing but boot loops my other is still on 442 and I wont be updating it as its working fine. I have been reading a few posts and the problem was right in front of me all the time I have 2 internet connections 2.4 GHZ and 5.0 GHZ if I connect to the 5.0 GHZ I get boot loops but if I stay on 2.4 GHZ no problems what so ever so I may just install a custom rom and my 10.5 tab and stay clear of the faster internet.

Bluetooth App Missing, Random Reboots, Deleted System Partition, No ROM in Storage

I've also posted this on Reddit and the OnePlus forums, but I'm hoping I can find an answer here, too.
Long story short: I really messed up my phone and I'm looking for help getting it to at least boot into the system. Lots of weird, confusing things have happened within the past few days, so bear with me; might be a long story, but I'll try to give you the abridged version.
I run locked and unrooted. I flashed OOS Beta 3 over 4.7.6 on my 5T, wiped my cache, and everything was wonderful for a week. Then one day, I got a system message saying "Bluetooth has stopped". I cleared that and thought nothing of it, but I got another message saying "Bluetooth keeps stopping". This message would actually pop up (with no exaggeration) every second. I could only stop the messages completely after going to the Bluetooth app and clearing the data, then disabling Bluetooth Scanning.
I figured the problem would fix itself, but the next day when I tried to connect to my car via Bluetooth, my phone would freak out again like the previous day. I had to listen to a CD like it was 1996. I thought I could fix the problem with a Factory Reset. As soon as I hit the Welcome screen, "Bluetooth has stopped". When I went to check the Storage section of the Bluetooth app in the Applications list, the app portion read 0 bytes. What? Even when I went into Settings --> Bluetooth and tried to turn it on, nothing would happen. I thought maybe I should revert back to 4.7.4 and start from the very beginning.
That served no purpose. The Bluetooth symbol did show temporarily in the Status bar as I was setting up my phone, but eventually disappeared, with the Bluetooth app once again taking up a whopping 0 bytes. I've done various combinations of installs, but I cannot get Bluetooth to function normally. And at some point, my phone developed a new problem: any time I hit the Bluetooth button in Quick Settings, the phone would eventually reboot on its own. Later, it wouldn't need any input from me at all. It would just be sitting in the Lock screen and reboot.
Icing on the cake: I got desperate, unlocked the bootloader, deleted the system and cache partition in fastboot, then wiped the data in Recovery with the hope that doing a completely fresh install would fix the problem, but at some point my internal storage got wiped and now I have no ROM on my phone to install. Even better: I'm having some real problems trying to install OOS (any version) on my phone via ADB sideload. I keep getting the message "cannot read <filename.zip>", even though it's in the correct folder.
I am currently back on my OnePlus 3 and the proud owner of a very sleek brick. I used to root and unlock Nexus devices and Moto X's, so I'm pretty embarrassed that I managed to ruin my phone while it was running (basically) all stock. It can still boot into Bootloader and stock Recovery. Is there anything at all that I can do to at least load OOS (or any ROM)? Do I have to send it back to OnePlus and beg for a replacement? Will they even take this phone in it's current state? Am I just SOL?
I've run out of ideas and patience. I'm really hoping someone out there can help me. At the very least, thanks for reading my long sob story. Hopefully this never happens to you.

try flash orero based twrp and flahs stock 5.0.3 zip in twrp, see if it works. then figure out the reset.
Why would you delete system from fastboot? Does people not formating partition from recovery more often？
The twrp I use

Update: I managed to unbrick my phone using an unbrick tool. The process was pretty painless and it will revert your 5T back to OOS 4.7.4 no matter what you did to it. Props to Drasm19 from the OnePlus forums and the geniuses behind this tool! Funnily enough, I was ultimately led back here:

You guys more than likely already knew about this tool, but definitely keep this in mind if you manage to brick your phone like I did.
Now I'm back to my original problem: Bluetooth is really messed up. This is what I'm talking about:

No matter what I do, no matter how many times I flash any version of OOS, this is always the result. As you can see, even with the toggle in the "on" position, Bluetooth refuses to do what it's supposed to do and the app takes up 0 bytes. Something is up...
I've searched a lot of threads that reference Bluetooth issues, but it looks like I'm the only one with this problem. I'm open to any and all suggestions that'll help me solve this and get back to using my 5T. I already miss those awesome navigation gestures.
Thanks again for your time and help.

im not really a developer type, but a while back it was easy to root and un root with kingo. and i could put things in the system with FX. please bare with me a sec.. p9's i like, but getting some glitches. when the gboard went byby, on reset, i had to set up my welcome screen by shouting at the phone.. 'at sign' does give you @ but to get capitals you have to trick it, eg. 'USA' to get an upper case 'u'
anyway, i got in, and got gboard from 'my apps' ..fine but of course, wont survive another reset.
so about the missing bluetooth.. iv got the directory info. and the missing files. thanks ..but i didnt want to wipe the phone, it seems rooting has become a can of worms.
wouldnt it be nice if there was a nice (no root) app , to run bluetooth from the apps ? so that 'joe blow' doesnt have to throw his phone away, cos it doesnt work in the car ect.. thanks
