Hi all,
I recently took the plunge into the Android world of things and loved it. Everything was going according to plan, until I decided to try out the DSU loader and load a GSI package. Based on everything I read it shouldn't had cause any issues, but unfortunately it did. Once I rebooted the phone I received the dreaded "Your Device is Corrupted and Cannot Be Trusted" message. Unfortunately it all went down hill for me from there. A couple of things I know now and shouldn't have done without knowing more information was performing a "Format and Download" option on the phone. Had no idea I was going to loose other partitions that is not created by the flashing of the Rom.
I was able to get the Manufacturer Rom and flash it back to the device. Everything appeared to be working fine until I noticed that I was not getting any data for the battery management option. Another thing I noticed is that now my battery is rapidly loosing it's charge. Could this be related to the Cache Partition not being present? Is there anyway to get the Cache Partition back or recreate it by rooting the device? Any suggestions would be greatly appreciated.
Thanks,
-Glitch

Had just flashed the latest CM9 nightly (clean install, fresh wipe) yesterday and everything was running fine.
This morning, woke up, my phone was turned off. When powering it on it hung on the google screen. Fastboot still working, booted into recovery only to find that I would get error messages when trying to load my backs "E:unable to mount /sdcard". Apparently it also couldn't mount /data. So I was unable to flash any images or restore or boot up.
Seeing that fastboot was still working I assume I'm not bricked yet. I tried flashing a new boot and cwm recovery via fastboot - no dice. Same errors.
I don't have a recent backup of anything in sdcard, but at this point I'm willing to sacrifice it.
Found this thread http://forum.xda-developers.com/showthread.php?t=1078213
and I'm trying to follow the steps to flash back to stock GB. using the GRJ22 images
It flashed the boot and recovery without issue but seems to hang while flashing the system.img. I know it's a big file, but it was up to ~2hrs with it still transferring. I pulled the plug on it and tried again, lost patience after an hour.
Now I had the idea of maybe locking and unlocking the boot loader would help things.....not sure why I thought this. Anyway, now it seems to hang on the unlock bootloader screen.
So my question now - am I screwed?
- anything else to try?
- is it really "hanging" or do I need to give it more time?
- have I screwed myself even more by now locking my bootloader and flashing the stock recovery?
Any help would be very much appreciated....
Some new additions and new insights from the reddit android community:
- this probably has nothing to do with CM9. My phone has been wonky for about two weeks - random reboots, sometimes rebooting into recovery. That's why I thought I'd throw on the latest nightly and do a fresh wipe yesterday.
- There's definitely something up with /data. Anytime I tried wiping all/factory reset in cwm recovery I got errors about not being able to mount /data or being able to find files in /data
- basically anything I do involving /data partition causes the phone to lock-up -- flashing the boot.img and recovery img worked, but not system. Also, I think the reason I can't re-unlock the bootloader is because during the unlock process it tries to do a factory reset/data wipe
Basically I think there are two things I need to know if I can do - 1) unlock the bootloader again, via some way that won't try to reset the /data partition and thus won't freeze the phone. 2) try repartitioning /data
I really hope I didn't screw myself by locking the bootloader. I'd actually feel a lot better if it was something in my phone that just failed hardware-wise rather than something I could've fixed if I wasn't too quick to try poorly thought out ideas.....
Any help at all would be appreciated!
Possibly (and likely) a corrupted nand flash. Fairly common problem sadly. I'd say it's a good thing your bootloaders locked, no dramas sending it back to samsung. It might've been possible to reset the partitions and flash fastboot images but i don't think i've seen anyone who has done this to sort any similar problem. Hopefully your phones still under warranty
Well thank God that it turns out that I'm still on warranty.....sending the phone back to Samsung tomorrow.
Like you said, it's actually a good thing the bootloader is now locked and the stock boot img and recovery img are now back on! Hopefully this makes it more likely that they weren't turn away my phone.
I've yet to hear someone not getting work done under warranty because of an unlocked boot loader but it's always good to have it as stock as can be. Hope they don't take too long with your phone.

I bricked my nexus s 4 days before Christmas last year... and i was using a custom rom obviously with an unlocked bootloader and custom recovery image, and i handed it to vodafone, and guess what? they repaired without asking any questions, and the day before Christmas! sooo happy maybe because i was thirteen then, they didn't suspect a thing
Hey guys. Before I get to my issue and seek your help , please allow me to give you a bit of background about my self wrt Android OS and nexus devices. I have been a Nexus device user since the N1 days. OS flashing , Custom rom's , kernel patching , etc are nothing new to me. I can safely say that I am a custom rom addict , hence I know the mods for my devices intricately well. With this out of the way , I'd like to share the sequence of events that took place yesterday , which lead to this new thread , wherein I desperately need some expert advice.
- I was running the latest Bigxie 5.0 rom for my 32gb N5. It had root and TWRP and elementalx kernel
- I wanted to upgrade to the 5.0.1 without losing any data , so I first tried to sideload the OTA zip file , which failed with some error. I then followed this guide (http://bit.ly/1wNT36l) . I was able to therefore flash the 5.0.1 without losing data. I re rooted my phone , re flashed the recovery and the kernel
- At the same time I was upgrading my LG g3 to Lollipop. I wanted to try the "Tap & Go" data transfer feature , so I used that process to transfer the data from my current N5 to the new G3. Here is when the issue started. The data transfer didn't go through , as only the email accounts transferred to the G3. At the same time , I got this notification on the Nexus that Tap and Go was used to transfer my email accounts , and this notification couldn't be cleared from the notification panel. For some odd reason , I decided to jump back into recovery and wipe cache and dalvik cache to get rid of this notification
- As soon as I did that specific wipe and restarted the phone , the phone would just loop at the nexus image boot screen. 15 minutes later I went back into recovery and decided to use the "factory reset wipe". That too didn't solve my problem. Frustrated at the turn of events , I reflashed Bigxie's 5.0 rom from my internal storage , via twrp.
- The phone finally booted! But now the problem was that my Sdcard was showing no files. It was all blank. I checked with root explorer / es explorer and even when I hooked up my phone to my pc , the sdcard was showing no files. I could , however , see all my files in the root -- data -- media -- 0 folder. I tried my best to extract all my files from there , but each time I got an error that pretty much meant that no files could be moved from there. Interestingly , when I went into twrp , and went into file manager in the advanced options , it showed all my files on the sdcard as though nothing went wrong. So I could see everything on the sdcard in recovery , but nothing if i booted into the OS.
- Since I had made a backup of most of my data prior to any this happening , with the exception of certain whatsapp data , and after having spent almost 5-6 hours in figuring out where I had possibly gone wrong , I decided to wipe my device clean and just install the stock OS and pack this device away for good
- I downloaded the stock factory image for 5.0 from the official site and went back into bootloader and fastboot flashed each and every file. The phone booted , BUT , now my phone showed only 12GB as the size of the storage with 11GB available. This frazzled me beyond words! How did I reach this stage wherein my internal storage was screwed to this level?
- I again went back into bootloader , flashed 5.0.1 , wiped the device and now the phone is again stuck in a bootloop on the nexus bootscreen
I have finally decided to send the device to the LG service center near my office , but I wanted to share this experience with the community hear and seek their guidance on where I possibly went wrong and what I can do now to put things back together to some degree of normality. Have I somehow damaged something at the hardware level that a change of motherboard may be warranted or is this a pure software screwup?
Thank you for your patience in reading this loooooong story , but I had to explain each and every step in perfect detail.
after flashing stock image.. there is no need to wipe anything... just boot it... takes around 5-10mins max but comes up.....
When it does 12GB on a 32GB device, you just have to factory reset using the option from inside the ROM.

Well said , and understood. I followed a different set of instructions and flashed back to stock and fixed my device. Thank you for your help.

haha no problem, i thoguth i was an experienced user too, but then i bricked mine by flashing lg g2´s rpm partition to get a different partition layout. lol. glad you got your n5 back
Hi
The tab P6800 I got here with me had data corruption, boot-loop. I tried to flash CWM/TWRP using odin to backup the data first, but unfortunately whenever flash complete (without error) and the device reboot, it still go back to stock recovery. I think this tab had some kind of protection.
Gaining root in stock recovery, I managed to backup the data using dd. However when I tried to wipe and reboot, nothing changed. It boots back with all previous data intact.
Then I tried to manually zeroed out the partition using dd. No luck there, stills intact.
Tried to mount the data partition, delete and write some stuff into it, it can successfully delete, write and read back. However when rebooted, the data is gone and back to where it was before. Which probably means the data written before probably cached into ram.
Is the memory is in some kind of read-only mode? Is there is any fix for this? Or is it just emmc wear out and need a board replacement?
Sorry to hear your experience, it does seem remarkably similar to mine that I posted here
http://forum.xda-developers.com/galaxy-tab-7-7/help/wont-install-rom-wont-install-apps-t2908578
I never did find a solution though but if you get some success I should love to hear it.
Likewise I suspect the emmc, I think I have the superbrick bug as I recall running the test app when I first got the device. So I am guessing this has manifested itself. Very frustrating too, my Tab is in tip top condition otherwise.
Sorry to hear you too.
I already tried everything I can think of except NAND erase and Flash lock on ODIN. Don't know what flash lock means though.
Guess replacing emmc/board is the only way to solve it now.
I'm giving up.
Hi ~
- Be kind with me, it's my first post! -
I'm facing a very bad problem with my Galaxy S6. A week ago I received an OTA from Samsung and I installed it. My phone rebooted and showed the bugdroid, meaning that the update was progressing. After that, the device keep rebooting over and over just after I entered my encryption password. I said to myself that I can try to wipe the cache because maybe an application was causing this problem. But now, the device is only showing the Samsung logo then just shut himself off.
Now I need your help to get my data. The hard part is that my device is encrypted. After many hour of search I see two solutions:
Flash the rom via ODIN
Install TWRP which can read encrypted volumes
The first solution seems easy and I keep the warranty. The problem is that I'm not 100% sure that flashing the rom again will not touch the /data and /sdext partitions (and the header/footer where master key are to decrypt the volume).
The second solution seems safer and should not touch any other partitions. But knox counter will be incremented and I will loose my warranty.
So, does anyone could test if flashing the rom via ODIN do not absolutely touch encrypted volumes and certificate that I will be able to get my data again?
Thank you a lot
Have a leap of faith. Go ahead and flash. Otherwise bring it to Samsung for warranty repair. They may be able to recover your data for you.

I want to be sure and I don't want to loose any photos if possible, so no
I already tried to go in a Samsung repair store (Allo PSM), but they just don't care about my data, their job is just to make the phone working again.
So Anyone is able to confirm to me that flashing stock Galaxy S6 ROM (AP Via Odin) doesn't touch the /data and /sdext partition that are encrypted?
After many hours of search, I was able to make my phone working again!
For anyone concerned by the problem in the future, here's some informations:
You can flash a stock rom, your encrypted /data will not be erased and you will be prompt to enter your password on the next boot
In my case flashing a newer rom didn't solve my problem (bootloop after entering the password of the encrypted partition). I had to flash the rom that was in the phone before the OTA.
Now everything seems to working again. No data were lost, all my configuration was saved. Android showed a message that a problem occurred during the upgrade process and I sent logs to Samsung, hoping that it will help them!
So it has been quite some time since I've been on these forums or tinkered with any phones. I believe the last one I rooted was a Thunderbolt.
Anyways, I have recently tried to root my Note 4 Edge and I hate to say it but I got cocky and rushed through it and now I am in trouble. (I know -- stupid)
I followed this guide (http://forum.xda-developers.com/note-edge/general/easy-steps-stock-odin-n915tuvu1anjl-sm-t2943993) and everything was working right, followed the steps and what not. Unfortunately I did not create a backup of my last known working boot (Again, stupid, I know.) Needless to say, when I went to boot my phone up it was in a boot-loop. So I tried a wipe of everything using TWRP, everything except Micro SD and internal storage. Tried it again after the wipe, I get an message from TWRP saying that I have no OS (oh, great to see after flashing a rom).
After messing with that for an hour or two just to try and get my phone "working" again I gave up on it and tried using a ROM called HyperDrive, I think it's called. Wiped everything needed before flashing the rom, installation went smoothly, no "NO OS" message from TWRP. Rebooted phone, and what do you know, another boot loop.
Its been a while since I've tried tinkering with my phone, if anyone knows of what I did wrong or knows how to fix it I would greatly appreciate it considering ill need my phone for work tomorrow.
Please, and thank you.
Of course you wiped the system so no OS, i suggest you flash the stock rom via Odin first.
