May be someone can help may be the bootloader is locked, doesn't boot installed Lineage and it's bricked - Galaxy Note 10.1 Q&A, Help & Troubleshooting

I have bought an gt-n8010, which has lineage os installed, but doesn't boot (just splash screen).
So i tried odin to flash the stock rom, but it failed any writing process on the device. In Download mode there is some info written:
ODIN MODE
PRODUCT NAME: GT-N8010
CURRENT BINARY: Custom
SYSTEM STATUS: Official (What does it mean? Does it mean the Bootloader is locked and the device is bricked?)
RP SWREV: A2
But twrp (2.8.7.0 or so) is/was installed, so i booted into recovery and tried to install other custom roms, but it also failed. "Can't state /data/media".
The File Manager in TWRP shows /data but couldn't enter /data/media.
I remounted /data as RW (at least i thought first, that i did) and the file manager could show me /data/media and i thought i was sucessfull.
But the ROM i had, didn't want to install (it thought this was the wrong hardware) and the /data folder was still mounted Readonly (/cache too).
I loaded another ROM, but that needed a newer TWRP.
So i tried flashing TWRP through TWRP and failed. Tried with Odin and Failed. Tried with the DD command within TWRP and failed.
I realised /cache and /data were still mounted read only (and i assume that this is the same problem in Download Mode when trying to flash with Odin)
So, has anyone any suggestion why i can't get /data and /cache mounted in RW mode and has a solution?
Or are these just symtoms of a locked bootloader.
Finally i got it mounted rw (both Cache and and data) und could copy a file to the /data/media folder, by umount and then mount manually.
Still i either need to upgrade twrp or get a ROM which works with twrp v2.8.7.0, so any suggestions? May be dd with the right /dev/blk.... instead of "dd if=/external_sd/twrp.img of=/dev/block/platform/dw_mmc/by-name/RECOVERY" (fails with writing with I/O Error) may work. But i don´t know which one it is.

I would try to flash a recent TWRP from in the download mode and see if this works.
If there's still the old TWRP after the flash than your eMMC is locked and needs to get replaced.

Is there any other possibility to flash from Download Mode except from Odin3 which i already tried. (Adb doesn´t seem to work detects no devices, fastboot neither).
And why does twrp mount /cache und /data read only on start up?
I also thought that something may be locked, but finally i could mount it RW in twrp by mounting it manually by using umount and mount with tha same options except rw instat of ro.

Sure, you could use heimdall (linux). But Odin 3.09 should work fine for example.
Does it even detect your device?

Yes it detects the device, it connects to the device but it seems it can´t write anything. I´ll post a screenshot later.

[Q] Bootlooping with a locked bootloader and unmountable sdcard

Is this phone salvageable? I have quite the odd problem. I have plenty of backups, so I'm not worried about fully wiping the Nexus S.
I was running CM9 Alpha 11 when I heard about the ICS 4.0.4 OTA update for the I9020A. I rebooted into my recovery to make a nandroid backup. That's when the problems started. Mounting /sdcard, /system and /data fail, but mounting /cache works. Attempting to mount to USB Storage gives a "Unable to write to ums lunfile" error. When I noticed that the backups weren't taking, I tried to reboot normally but encountered bootlooping. As a last resort, I tried "fastboot oem unlock" but it freezes. Battery pull gives "FAILED (status read failed (too many links))" on windows.
Model: Nexus S I9020A
HW Version: Rev 16
Bootloader: I9020XXKA3
Baseband: I9020UCKF1
Carrier: ATT
ROM: CM9 Alpha 11
Recovery: ClockworkMod Touch Recovery v5.8.0.2
Bootloader: Locked
Busybox: v1.19.3-cm9
Accessible: fastboot, adb, adb shell with #, busybox, and recovery.
Symptoms: Bootlooping, unmountable /sdcard, /system and /data, cannot mount to USB Storage, bootloader does not unlock.
EDIT: Found this unfortunate bit of news. Looks like I'll be sending it in for repairs and hoping they won't notice the recovery.
EDIT2: I found out that I can flash zip files through a roundabout method to mount /cache as /sdcard. Unfortunately, all I've been able to do is to flash recovery since system and everything else isn't mounted. I haven't been able to get ./flash_image to work. I've tried making the mounts executable as well as flash_image. My last option is looking for the "Android system recovery <3e>" in the form of a .zip and flashing that so it looks like my warranty is still intact.
adb push update.zip /cache
adb shell
mount /dev/block/mtdblock4 /sdcard

After this, you can use the recovery to flash the update. So far, I've tested going back and forth between ClockworkMod Recovery 5.0.2.0 and ClockworkMod Touch Recovery 5.8.0.2.
EDIT3: ./flash_image doesn't work. However, flash_image works because I have busybox installed on my phone.

[SOLVED] Decryption Unsuccessful and a currently bricked M8

I previously ran LolliGPE but was long overdue for an update. I downloaded the latest version and copied the image to my phone and flashed the ROM. I decided to go try a dirty install first to see if I could keep everything I had, since I had already been running a previous version and after reviewing the changelog did not see anything recommending to wipe clean. After installing successfully, Android asked me to enter my password to decrypt my data (I don't recall ever encrypting my data?), and so I did. It then told me that my password was right, but the data was corrupt, and presented me a button to reset my phone. The button redirected me to recovery and automatically attempted to wipe /data and then re-mount it, but the wipe failed. I rebooted again with the same issue, same failed attempt to wipe. I went to install the zip again, and this time do a full wipe, but it was unable to mount my phone's storage nor my SD card. I am not able to mount either at all now.
What's the best course of action? I'd like to retain as much as I can and avoid wiping all of the internal storage clean. Is there a simpler fix to this or am I doomed?

EDIT: For anyone else having a problem like this that at least wants to get their data back, here's what you should do (I assume you know how to work with Linux!):
Make sure you have the latest version of TWRP and ADB.
Boot the phone into recovery mode and connect the phone to your computer via USB
Run "ls -al /dev/block/platform/msm_sdcc.1/by-name" and check the output. Make a note of the partition marked "userdata" - for me, it was /dev/block/mmcblk0p48.
Either: simply use adb pull to copy this file to your computer (this will require about 26 gigs of space), or attempt to mount the file. To use adb pull, execute "adb pull /dev/block/<ID> ./data" (ID being what you marked down). Your data partition will be copied to /data. To mount, use "mount -t ext4 /dev/block/<ID> /userdata". Whatever's left of your data will be on your phone's new /userdata folder.
Use ADB to pull what files you want from /userdata. If you pulled the partition, skip this step.
If you copied the files you wanted over, you're done. If you pulled the entire partition, you're going to want to try and mount it. On Windows, there are various tools to mount Linux partitions, a quick Google will find some good ones. However, if the data is corrupt, it will not work. I recommend attempting to repair the partition on linux, with the command "e2fsck -f -y /path/to/data", replacing the path to your data file as necessary. Once done, run "mount -t ext4 /path/to/data /mnt/data", replacing the paths as necessary.
Once mounted, you can access your data wherever it was mounted. If e2fsck appeared to fix many errors, chances are most of your data will be in the lost+found folder, and you'll need to sort through this yourself. If you're lucky, then your data will be intact and readily usable. Internal SD card data is located at ./media/0.
To fix the partitions and get Android back up and running, you need to install the latest firmware, format your data in TWRP, factory reset, and then flash a ROM again. Here's what I did to do that, without an SD card. If you have an SD card, simply copy your ROM zip to the SD card and skip the final steps:
Make sure you have the latest version of TWRP and ADB, and download the latest copy of the firmware (check the development forum here).
Boot the phone (doesn't matter to what) and run adb reboot bootloader. When your phone reboots, double-check by running fastboot reboot-bootloader.
Put your phone in RUU mode with fastboot oem rebootRUU. The phone will restart and the HTC logo will come up.
Wait a couple seconds, then run fastboot flash zip firmware.zip, where firmware.zip is the firmware you want to flash.
The first time you do this, it will fail saying something like "FAILED (remote: 90 hboot pre-update! please flush image again immediately)". Ignore this, run the last command again: fastboot flash zip firmware.zip
The progress bar will appear and begin filling. Wait until fastboot is finished flashig it (the progress bar may not fill completely), wait an extra 5 seconds or so, and then do fastboot reboot.
The phone will reboot. Android will still be messed up, but you can verify the partitions are in working order by checking adb shell cat /proc/emmc.
Once you know the partitions are working, get back into TWRP/recovery: adb reboot recovery
Format /data and wipe /cache, /data, dalvik/art cache, etc (factory reset). You will lose the contents of your internal storage and everything else.
If you don't have the ROM zip on an sd card, make sure the zip is in the same directory as adb and run adb push rom.zip /sdcard/rom.zip, where rom.zip is the ROM. You can also copy it to the external sd by swapping /sdcard/rom.zip with /external_storage/rom.zip.
Once copied, reboot into recovery and flash the zip. Back to normal!
Update:
It's a firmware problem. Apparently there was a new firmware update that the ROM uses that I don't have. mmcblk0p42 was changed to "vzw_logger" (which I don't have), making mmcblk0p49 userdata instead of previously mmcblk0p48. The data partition it expects to be /data is /cache. Got this information by comparing 'cat /proc/emmc' with information of the latest version I found here.
Is there a way to fix this that allows me to preserve the contents of my internal storage (/sdcard)? Can I just flash an older version of the ROM to backup my data?

I posted a warning about this change in the general section early on. For you to have the partition changes means you are on the newer firmware which doesn't match what you posted above for os. You very likely at this point have nothing left to salvage. Are you on the latest twrp?

I am on the latest TWRP, yes. Since this post, I've actually been making good progress in getting the data partition back, or so I think. I've been using dd to copy /dev/block/mntblk0p48 to an image file, but got stuck when I reached the FAT32 limit, so I re-formatted my SD card, except now it's read-only.

If you Dd the entire data partition it's gonna be almost 25 gigs. If you can't mount data in twrp and find anything usable when browsing via adb in twrp there's probably not anything usable in there.

I did a DD before while in ADB and it only got to about 1.3 gigs, but after running the image through e2fsck I actually found some images and downloads. I think there's usable stuff in there and I'd like to at least try to get it. There's family pictures and stuff on there that have some value to me. My SD card is 32 gigs so I could probably do it if anything for the hell of it.
Do you happen to know how I can get the SD card mounted? mount -o rw,remount /dev/block/mmcblk1p1 [some dir] is what I've been trying, but I've been getting either Read only filesystem or Invalid argument.
I might be a little crazy

Its already mounted.. Just boot into TWRP while connected to your PC. Open cmd prompt in your adb directory.
adb shell
cd sdcard
ls
See if your internal SD card contents are listed.

TWRP lists the internal SD card as being size 0 under Mount -> Select Storage and /sdcard is empty. I re-formatted my external SD card to make a full size image but that's what wasn't mounting.

I got all of my data back successfully. I'm updating the OP with the steps I did to get it back.
What's the next step? Change firmware? I have a local copy of what I needed from the phone, so anything's game now.

I would say update firmware. Since you confirmed blk48 as user data I know you don't have lollipop firmware.
I posted a firmware zip that contains the newest twrp which is compatible with lollipop in tigerstowns firmware thread. You can use that to update.
Then wipe and reinstall whatever Rom you want to use.
I fixed it this morning by updating firmware and will update the OP with the rest of the steps for the Googlers. Thanks again.

I have a laptop running Ubuntu: where do I run the "ls -al /dev/block..." command? As in what folder do I need to be in? The phone only appears in an mtp capacity...
EDIT: I figured that out but now I am stuck at "adb pull /dev/block/<ID> ./data". My ID was mmcblk0p28 but the command returns "Bash: mmcblk0p28: no such file or directory exists"
EDIT 2: Got that command to work but the file is too large to write (My disk is FAT32 ). So I then tried the mount command but again got "no such file or directory exists".
Same Issue "Decryption Unsuccessful"
I was trying to apply the OTA update for 5.1 on my M8 converted to GPE 5.01, but had to update to the stock recovery, and found myself in the same situation with the "Decryption Unsuccessful" message.
Following Klayderpus' steps to recover, but I'm running into a few issues:
1) Windows not Ubuntu so some (many) of the commands do not apply.
2) The device is not responding to adb, although it was prior to the "upgrade". Fastboot is working.
3) TWRP was not on the device, in fact I never could get to the recovery after trying to install the stock recovery when I converted to GPE 5.01 many months ago
I have a fresh nandroid backup, so I am just trying to get the device running. Being without the phone is causing me great pain....
I upgraded the firmware to 4.16 and did the factory reset from the stock 4.16 recovery. The phone boots back to the "Decryption Unsuccessful" message.
I am not sure, but I think the next step for me to try is to install the GPE ROM from graffixnyc from the microSD card (need to find/buy that little SD adaptor)
Any help would be greatly appreciated!!
========================
Update;
Recovery does not see the SD card , so I won't be able to install from there.
I'll try flashing TWRP recover to see if that will show the contents of the external card
========================
Update 2:
TWRP does see the external card, but the install failed as it is unable to mount /data and /storage.
I'm out of ideas....HELP!!
========================
Update 3
I noticed the "factory reset" in HBOOT and thought I'd try that instead of the "Wipe" in TWRP, but only made things worse.
Now the phone comes up to the "Decryption Unsuccessful" where I can then take the reset to get it into TWRP recover
TWRP comes up directly into a screen where it's "Running OpenRecovery Script" and then reboots.
I'm going to quit now, as I am only making matters worse.....
========================
Update 4
I got TWRP to quit whatever it was doing.
Now, In TWRP > Wipe > Advanced Wipe, I cannot wipe or repair the Data partition. I see a message "Could not mount /data unable to find crypto footer". Trying to wipe the Davlik Cache fails, "Unable to mount /data, " Unable to mount storage".

I've bricked the phone and it looks permanent.
I found another thread where everyone was solving this issue running this command "mke2fs -T ext4 /dev/block/mmcblk0p8" in TWRP. I failed to notice that it was not an M8 device thread. The phone won't boot at all, and windows sees it as a usb drive.

Do you still have fastboot?
Check out the RUU collection here and grab what apllies to your device:

Make sure you use the HTC fastboot.exe from post 3

If you have fastboot do the following commands
Fastboot oem task 28
Fastboot oem task 29
Then try to flash your rom or ruu.

Either: simply use adb pull to copy this file to your computer (this will require about 26 gigs of space), or attempt to mount the file. To use adb pull, execute "adb pull /dev/block/<ID> ./data" (ID being what you marked down). Your data partition will be copied to /data. To mount, use "mount -t ext4 /dev/block/<ID> /userdata". Whatever's left of your data will be on your phone's new /userdata folder.
Use ADB to pull what files you want from /userdata. If you pulled the partition, skip this step.
If you copied the files you wanted over, you're done. If you pulled the entire partition, you're going to want to try and mount it. On Windows, there are various tools to mount Linux partitions, a quick Google will find some good ones. However, if the data is corrupt, it will not work. I recommend attempting to repair the partition on linux, with the command "e2fsck -f -y /path/to/data", replacing the path to your data file as necessary. Once done, run "mount -t ext4 /path/to/data /mnt/data", replacing the paths as necessary.
Once mounted, you can access your data wherever it was mounted. If e2fsck appeared to fix many errors, chances are most of your data will be in the lost+found folder, and you'll need to sort through this yourself. If you're lucky, then your data will be intact and readily usable. Internal SD card data is located at ./media/0.
To fix the partitions and get Android back up and running, you need to install the latest firmware, format your data in TWRP, factory reset, and then flash a ROM again. Here's what I did to do that, without an SD card. If you have an SD card, simply copy your ROM zip to the SD card and skip the final steps:
Make sure you have the latest version of TWRP and ADB, and download the latest copy of the firmware (check the development forum here).
Boot the phone (doesn't matter to what) and run adb reboot bootloader. When your phone reboots, double-check by running fastboot reboot-bootloader.
Put your phone in RUU mode with fastboot oem rebootRUU. The phone will restart and the HTC logo will come up.
Wait a couple seconds, then run fastboot flash zip firmware.zip, where firmware.zip is the firmware you want to flash.
The first time you do this, it will fail saying something like "FAILED (remote: 90 hboot pre-update! please flush image again immediately)". Ignore this, run the last command again: fastboot flash zip firmware.zip
The progress bar will appear and begin filling. Wait until fastboot is finished flashig it (the progress bar may not fill completely), wait an extra 5 seconds or so, and then do fastboot reboot.
The phone will reboot. Android will still be messed up, but you can verify the partitions are in working order by checking adb shell cat /proc/emmc.
Once you know the partitions are working, get back into TWRP/recovery: adb reboot recovery
Format /data and wipe /cache, /data, dalvik/art cache, etc (factory reset). You will lose the contents of your internal storage and everything else.
If you don't have the ROM zip on an sd card, make sure the zip is in the same directory as adb and run adb push rom.zip /sdcard/rom.zip, where rom.zip is the ROM. You can also copy it to the external sd by swapping /sdcard/rom.zip with /external_storage/rom.zip.
Once copied, reboot into recovery and flash the zip. Back to normal!

Can't flash anything through recovery. (failed to mount "/cpefs" (Invalid Response)

Can't flash anything through recovery. (failed to mount "/cpefs" (Invalid Response)
I recently got this phone and I've been trying to install a custom rom, however, I can't seem to do anything while using TWRP. For some reason the file explorer shows no files and no /storage folder. It also says that the /system partition weights 0MB. I've already tried formatting the /data partition from EXT4 to extFAT, but it won't let me because it cannot mount the "/cpefs" partition, which I've been unable to find any information about.
I can flash the stock firmware trough ODIN, and I can flash the recovery. The internal storage works fine, but nothing shows up when I open TWRP.
I've tried formatting the data partition, repairing it, changing the partition format, wiping, installing a custom rom, installing superSU. But it won't allow me to do any of those things. Either "/data" can't be mounted, or "/cpefs" can't be mounted while formatting /data.

Which phone you're using?
J7 Pro?
Secondly make sure to enable OEM unlock options from the stock ROM's Developer option!
Thirdly check the recovery patches etc of the desired recovery's webiste (you're using) and flash it through the recovery if you're facing the problem!
It'll work, mostly some users said they fixed this by the above mentioned step!
If no luck, maybe someone will sort it out for ya, soon! :laugh:
Good Luck! :good:

Thanks for your reply. The model of the phone is SM-J710MN. The OEM unlock option is enabled, otherwise I wouldn't be able to flash the recovery. I am trying to use TWRP. Where would I find a recovery patch for this model?. Everything works fine in the recovery, but it won't let me wipe/format/repair or change ANY partition. It can't mount anything, and the error that I see the most often is that it cannot mount the /cpefs partition.

try flashing a lower version of the same frimware you've already installed e.g if the latest is nougat 7.1.1 with the recent security update, try flashing with another nougat version that is lower to the recent one's security patch #

Is my OP 7Pro permanently broken?

I have an OP 7Pro (GM1917) that was working fine for a long time with OOS 10.3.8.
I hadn't done an upgrade for a long time, and so recently, I did an upgrade to OOS 11.0.5.1.GM21AA. After doing that, my device is unusable, and I fear that there might be something broken or damaged that causes firmware or storage to no longer function properly. All of the explanatory details follow, and please read all of that. What I'm wondering is whether the device is now permanently hosed, or perhaps if there is some way for me to fix it. Here are all of the details:
After the upgrade, my device went into a permanent boot loop when trying to boot to System.
I then did fastboot boot twrp-3.6.0_11-0-guacamole.img, and it indeed put me into TWRP. However, the /data partition is inaccessible. Whenever I try to format /data, I consistently get these messages:
Code:
Failed to mount /data (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps
Unable to wipe data
I go back to the bootloader and connect to my PC, and I then run these commands:
Code:
fastboot erase userdata
fastboot format:ext4 userdata
These commands successfully run with no error messages. I then go back into TWRP, but /data is still inaccessible, and I get the same error messages that I listed above when trying to format /data .
I then tried to decrypt /data, but when I do so, it asks for a password, and I have no idea what password to give. I never used any password on the device in the past. I am not allowed to decrypt /data without a password.
So, I decided to use the MsmDownloadTool to reflash my device back to OOS 10.3.8. This works fine with a different GM1917 device that I have (but which I never tried flashing to OOS 11). However, with this particular device, after going into EDL mode, I am told that I am "Connected", but a couple seconds later it gives me the "Sahara Connection Failed" message. I have double-, triple-, and quadruple-checked the device drivers, and it indeed is showing that the "Qualcomm qds 9008" driver is properly installed and active. Furthermore, as I mentioned, I have no problem using MsmDownloadTool on that PC with another GM1917 device.
I went further: I extracted payload.bin from the OOS 11.0.5.1.GM21AA installation bundle, and I extracted all of the *.img files. I flashed boot.img via fastboot and retried everything that I mentioned above, but nothing has changed.
I then went and flashed all of the *.img files. However, still nothing has changed.
When reflashing the set of all *.img files, in some cases, I was told that the file is critical and cannot be reflashed. I then ran these two commands ...
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
... but in both cases, I was told that the device is already unlocked. Trying to reflash all of the *.img files again gave me the same results: i.e., some got flashed, and others were not flashed due to being "Critical".
Also, some of the items I flashed were said to be "sparse" and their flashes were flagged with warnings, but as far as I can tell, they seem to have been flashed anyway.
Do these problems with /data and EDL and everything else mean that my device is somehow permanently damaged? Or are there perhaps one or more additional things that I can try in order to restore it to some sort of working state?
Thank you in advance for any thoughts or ideas.
This has been fixed.
I had forgotten that in the past, I was trying the OrangeFox dual-boot recovery on this device, and it had repartitioned /data.
I fixed this by booting into OrangeFox recovery via fastboot, and then using its adb sideload facility to flash that recovery. OrangeFox's adb sideload mechanism offers options to the user for repartitioning and rebuilding /data. I utilized those options and set /data back to "Stock", and after that, /data was accessible again.
At this point, I flashed OOS 10.3.8, and then flashed the appropriate TWRP and Magisk, now, my device is back up and running in that OOS version.
The EDL problem continues, but given that my device is now usable again, I am not overly concerned about this MsmDownloadTool issue at the moment. In my spare time, I'll continue to look into that.
All's well that ends well!
I think I also have the same issue but the good thing with mine is my device is still working..but every time I access storage via twrp it give me a 0mb or in accessible data no matter if I enter my password to decrypt data. Until now I just leave it as is for I haven't found any solution
I have the same issue but I can't boot at all. I'm only limited to twrp and fastboot. I was previously running 11.0.3 with Magisk and a Magisk module called xXx_nolimit, downloaded the OTA update and went to reboot to recovery before being prompted for a pattern passcode (I hadn't set any fingerprint or password) so I rebooted into twrp and clicked fix bootloader. Now as I reboot it just boots back into twrp.
I'm also getting these same messages:
Failed to mount /data (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps
I'm currently running apbf to bruteforce the pattern passcode that I never set in hopes to decrypt my phone. Not even sure it will work though as I don't have FBE user 0 mounted? I have my dad's phone which basically has the exact setup as mine but I didn't update it yet. Anyway to use partition or parts data from his phone to fix mine? I really don't want to wipe my /data or /userdata as it's been a while since I backed anything up.
Edit:
All I have in my /data folder is:
/data/india
/data/recovery
/data/reserve
The edl issue happended to me too and I just needed to use another msmdownloadtool version.

help on twrp "fastboot flash"

Hi all,
i have pure AOSP A.13 installed, and after installation i accidentally flashed twrp 3.7 by fastboot flash.
Now, system boot from slot A works, but seems i corrupted somehting:
- at twrp, /sdcard is always empty, have to re-adb push images
- installing i.e. magisk, get such errors
failed to mount "system_ext" (Block device required)
Unable to mount /data/media/TWRP/.twrps
etc.
Super partition seems anyway ok, since AOSP boots fine.
Also, quite strange, Nord is A/B, but i still have recovery partition.
Is there any chance to recover ?
Thanks
