I have a Galaxy S duos 2 which isn't booting, and, when it rarely does boot, it shows "Device memory damaged", in recovery mode it displays "E:Failed to mount /data"; Factory reset did nothing, neither did flashing it, I tried installing CWM and TWRP, however, I failed at both of them, it keeps coming back to stock recovery. It isn't rooted or unlocked in any way, I also tried a full flash and, well, also nothing, and I am a little stuck now.
A few more things I tried:
— Re-partitioning;
— Removing battery after flashing
— Using another Odin version
— Using other ROMs
— Changing the recovery.img in the ROM for the TWRP's recovery.img
After a few tries I can't get it to completely boot, and it freezes anywhere except for the download and recovery mode, even the "charging" animation freezes. It also sometimes shows "No command" in recovery mode, or "Error", and it requires me to remove the battery and restart.
I truly don't know what else to do.
Obs: My phone model is GT-S7582L, I don't know if it actually changes something.
Obs: I don't really care about the data, it isn't my main concern, if it works, it's already great!

Hello all.
I'm new to modifying my android (Galaxy S7 G930A) and could use some help. I have successfully rooted my phone, but have had some issues trying to flash a custom recovery. I was trying to flash TWRP but for some reason it didn't work, and I would always boot into the stock recovery.
Today, I screwed something up while trying to figure out my host of issues (I was also trying to figure out why I kept getting a "dm-verity verification failed" notice when flashing). Using the TWRP Manager app, I tried to install the recovery that way and it kept giving me an error that it was either already installed or encountered an issue of some kind. Knowing it wasn't installed, I looked for a different route. Long story short, I downloaded Flashify and then manually downloaded and flashed the TWRP recovery img and a "no-verity-opt-encrypt" file - which I read would fix the dm-verity error I was receiving.
I believe that's all I did before this recovery boot issue starting occurring.
Now, when attempting to boot into recovery (no matter what way, through an app, manually, etc) the blue text "Recovery Booting..." appears for half a second and then disappears. If I'm holding down the buttons it will flash again and disappear again, over and over. If I don't hold down the buttons, when it disappears the phone boots up as normal. So now I can't seem to access recovery at all. I wanted to try going the hard/factory reset route, but obviously can't because I can't access recovery.
Also, I don't know if this is related or not, but now my laptop will not recognize my phone at all. Doesn't give me any options - it will charge, but no connection. I was hoping to load it into Odin and do a stock reset to start from scratch before flashing a custom ROM.
Edit: I tested and connected to a different computer just fine, so there's obviously some miscommunication going on between my phone and laptop.
Can anyone help me out here? Sorry for the long post, I'm just really frustrated. :crying:
Hi! So, my father's old Samsung Galaxy Tab 2 10.1 P5110 (bought 5 years ago) has gotten into a bootloop. It's an odd case. Basically, it's like the device is completely read-only.
To describe the symptoms:
It boots into the OS, but after 30 seconds or so it suddenly restarts. The device cannot be turned off (it just reboots and reboots and reboots...), so it empties the battery if left unplugged.
I can enter download mode and recovery mode, where the device is stable.
The device is not rooted.
I tried to flash it with TWRP recovery (it worked on my mother's tablet; exact same model, but no problem like this), but the recovery mode is always unchanged. I've flashed with Odin 1.8*, Odin 3.0*, and latest Heimdall; it always completes, but nothing changes. I've learned about having to boot to recovery after flashing due to a script replacing custom recovery, but even when I go directly to recovery mode, it's the same old stock recovery.
I decided to try another approach, by uninstalling apps during those short 30 second intervals of functioning OS; I got to uninstall one app (AVG anti-virus software), but after the reboot, the app was installed again.
I tried to go into recovery mode to do "wipe data/factory reset" and "wipe cache partition", but even that did nothing! Everything is where it was.
I can use ADB in recovery mode, so I tried to see if I could do some damage there, but the tablet is unrooted, and no rooting works either. (Tried rooting with Odin and "apply update from external storage" in stock recovery.) Couldn't find a writable directory to upload a su executable into either.
Just now I finished a 90 minute flashing of some Chilean stock firmware -- although I'm Swedish -- to see if that made things "rewritable", but guess what? All the old apps and files and settings were still there, in Swedish.
At this point I'm starting to suspect that I could hit it with a sledgehammer and it would just return to normal after a minute.
My father is not poor (just a bit cheap!), so buying a new tablet isn't a big deal, but I'm ostensibly a computer engineer...ing student, so it feels like a surrender to leave it unsolved. What might be the problem? Can memory in these devices become read-only due to some hardware fault?
Risky suggestions are welcome. If it's bricked, that's no problem.
EDIT: Whoops! My father ordered a new tablet; I was still going to experiment on the old one, maybe get it working again, but it seems that he went and tried the sledgehammer mode on it. But what happened is still an open question.
Trying to root my phone. Flashed TWRP in Odin, then installed SuperSU through TWRP. At the end it gives me the error in the title, and I get a 'failed integrity check' when booting into the system.
Help?
I've always read you have to do a factory reset after TWRP installation due to encryption, but apparently you don't have to
It still says you lose your OS though.

No factory reset required. Basically, the file system of your Data partition is incorrect and that is why it can't be mounted on to.
Go to 'Wipe'->'Advanced Wipe'->Click on the Data box->'Partition Options'->(You may be seeing values like 0mb for most of the information displayed and why you can't mount to it; if you are not let me know!)->'Change File System'->(Try out different File Systems until you being to see true values for the sizes, but avoid using EXT2 and EXT3 if you can)
Doing all this you will be able to Mount to your Data partition, however your OS will be deleted! So get your phone into Download mode, open up Odin program on your PC, and flash a Bootloader (BL) and your phone will be fine.
Then flash the 'no-verity-encryption-opt.zip' and then your SU Binary and Xposed Framework etc.
Good luck again Buddy!

Wait Install the No-verity zip first then, then flash a BL

It's a brand-new phone so I don't really care about the OS.
Also I tried restoring my Nandroid backup, but the drive appears empty when I go to the "Restore" option in TWRP. Not sure if I need to fix the data thing first anyway, but surely it should show up?
EDIT: Now that I think about it wasn't there some requirement to clear a cache at some point? I vaguely remember that from the last time I rooted an S7.
I've tried formatting, and the readout says "formatting" and then "Done.", but there's still a progress bar and the title area still says "Formatting...".
EDIT 2: It's plugged in but the battery is still dropping, and it only started at 8%. So it might just die anyway.
I recently went back and forth between Oreo and a TWRP Nougat backup, and was flashing TWRP each time I went up to Oreo because I was installing it via Odin which was blowing away TWRP.
I must have had to factory reset and flash the dm-no verity.zip a few times each TWRP install before I got /system and /data to not return an error. I was probably doing something out of order, but it always seemed finnicky.
How does one do the factory reset?
TWRP still reckons it's formatting, even though it says "Done.", but the battery has just hit 0% so it won't last much longer anyway.
EDIT: Or not...battery still going strong at apparently 0%. But it's been formatting for over two hours now.
Advanced wipe with data, cache, and davlik cache checked should be enough
When was I supposed to do that step? It rings a bell but it isn't in the instructions I found.
The phone finally died, and now I cant' seem to get past the TWRP splash screen.
EDIT: Just plugging it in results in the TWRP splash screen. None of the buttons seem to do anything, so I can't get into download mode and reflash TWRP or anything...
Okay, so I left it on the charger for a couple of hours.
Pressing and holding the power button turns it off. A few seconds after plugging it in, I get the Galaxy splash screen followed by the TWRP splash screen, and then the latter just stays there. Forever.
Once I turn it off, I'm unable to turn it back on at all - standard boot, recovery or download. I pressed and held the buttons for a full minute, made no difference.
EDIT: Leaving it off the charger results in the screen turning off a few minutes later. Again, no amount of pushing the buttons will do anything.
EDIT 2: Got it into download mode by plugging it in and holding the buttons down while waiting for it to automatically boot. Next step? Flash a bootloader, or reflash TWRP, or both?
Tried reflashing TWRP, changes nothing. Also tried flashing a BL and CP from the last time I installed SupermanROM, but it failed in Odin. Not sure if they're just too old or something, I have no idea how that stuff works or how updated my software is or anything.
It's the same handset I had before, but it had to go back to Samsung for repair because the battery blew up, so they very kindly wiped everything, reset Knox, etc.
Hi, here's a description of what happened, what I did to solve my problem, and where I am now...
I left my Google Pixel and 2 hours later found it stuck into a booting loop (Google logo displayed > black screen > Google logo displayed > blackscreen...).
I first entered fastboot and tried to power off, restart, etc a few times, but it stayed stuck into the booting loop.
So I downloaded latest OTA from Google for my phone (my phone was already updated to the latest version via the phone update manager, which goes back to december 2019 I think).
I first verified that my linux pc could correctly see the devices, and then from fastboot I entered recovery mode and chose "Apply update from ADB".
I used the adb command to load the OTA I had downloaded.
The update progressed until it finished with the following error message :
Code:
install from ADB completed with status 1
Installation aborted
E:Failed to clear BCB messages: failed to write /dev/block/platform/soc/62400.ufshc/by-name/misc: I/O error
I was back on the recovery menu screen, and this is where I think I did something stupid : I selected "Reboot system now".
The phone did not reboot, the screen just went black and stays black. The phone is cold so I guess not running anything. And it does not respond to any button, so not starting up, no fastboot, etc. No more when I connect it to a PC or plug it in a power plug.
I don't really care about the phone, I was just trying to get back my picture/videos from the last 6 months.
I don't have much hope but I will appreciate any help, even if its just to confirm that there is nothing to do

Well you could try and see if the phone is in deep flash mode, if it is flash system, boot and other sensitive partitions but make sure that the versions are the same. If you don't have the firmware you can pull user data partition from phone and get your data back that way

Thanks for your help. This is probably beyond my capabilities. I don't know how to check if it's in deep flash mode. Pulling the data out is what I'm interested in most.
Maybe this is something that a phone repair shop is able to do...

These phones get emmc errors. Common issue with this device
Hi guys, please I need your help. I got a samsung A7 (2018) device which doesn't connect to network though SIMs worked even showing my contacts.
I made research and found out I have root the device since the IMEI has been tampered. I rooted with Magisk, i.e patched my AP with magisk right on my phone then flashed with odin. After rooting I downloaded Super Tool as per instructions cause I read alot of articles and watched alot of videos.
Now that's when I messed up, all I know is, I clicked "Restore original IMEI" while my device was in download mode. And upon reboot I was greeted with an error message telling me something like "update failed, connect to Smart Switch, then click on Emergency Software Recovery".
Tried that, didn't work. I reflashed using Odin several times, with even using PIT and NAND Erase but still nothing. It's just stucked at boot logo and whenever I reboot to stock recovery, this "E:failed to mount /.system" message along with other writings like "#no data on recovery_cause#" show up.
I tried many methods found here on XDA and other sites but still nothing worked. I even installed the PBRP Recovery I saw here on XDA, though that worked but it still didn't fix my problem. And it failed to install zip. 'Cause I tried installing my firmware, said "zip verification failed" and other zip files I don't even understand the message it gave.
I tried wiping cache and formatting, change file system and repair file system, still nothing.
Whenever I try the "Run graphics test" in stock recovery it shows "Installing system update" along with gage, then "Error", then "No command" then "Erasing" along with gage and then back to Recovery.
and whenever i try "wipe cache partition" option
Wipe cache partition->
--Wiping cache...
E:[PDP] lstat /c____/pdp_b__:0 - No PDP Scenario
Formatting cache...
cache wipe complete.
cache wipe complete.
I cut the story short for convenience, but I know you quite understand all procedures I took.
Please help me with anything you have, I would appreciate it.
I tried everything myself cause I want to know how everything works and because I want to study Computer Science. I'm faily familiar with codes.
I'm really sorry if you find my English hard to read or digest, I didn't mean to make it hard for you to understand me.
Thank y'all.
