[Q] Restoring Stock ROM

Hi all,
I am stuck at stock recovery. Can anybody help me to restore stock ROM?
Here is the story:
After I root GTAB manually according to that thread http://forum.xda-developers.com/showthread.php?t=859712, I tried to apply the GPS trick explained @ http://forum.xda-developers.com/showthread.php?t=922692
Actually instead of using root explorer to place the files, I tried to replace files in zip file manually(via adb). It looks like something was wrong and device doesn't boot normally anymore. It just reboots to recovery instead. In addition, adb still founds device during recovery but "adb shell" gives an error saying link error. I assume "sh" binary was depending on one of the files I modified.
So, is there an instruction to restore stock ROM on the device.
My current recovery screen says:
Android System Recovery 3e
Samsung Recovery Utils
for BML
- Reboot System
- apply sdcard: update.zip
- wipe data /factory ...
- wipe cache
...
Installing Multi-CSC

All information related to flashing/recovering a device at recovery can be found at

I also had to use trick mentioned at that thread to get rid of blank screen after first boot:

Soft bricked Nexus 6P, bootloop

EDIT: A lot of Users have the same Issues, read about it here: https://productforums.google.com/forum/#!topic/nexus/iPnYjg322Q8
Edit2: this thread can be closed, thanks.
Hi,
i am stuck in a bootloop. I tried to find a thread with the same issue, but i wasn't succesful.
So here's what i've done and what's my problem.
Problem:
The Phone is stuck after the google logo, restarts .
i CAN get into TWRP/recovery/bootloader
what i did:
I flashed the factory images (even different versions) both via flashall.bat and manually typing.
after that i tried a new install and hard reseting, erasing cache afterwards.
I treid to adb sideload the Full OTA Roms, no luck either.
I tried installing Custom Roms(lineage, DU)/ EX Kernel on top of stock rom.
& the usual stuff like changing pcs, cables and usb ports.
The Flashing works fine everytime.
When i connect my N6P to my pc after flashing, it says 110GB free out of 110Gb.
EDIT: when i open file manager in twrp, i see a lot of folders (root, recovery, system, cache boot etc)
I thought maybe it is a permission problem or a filesystem problem?
Maybe i need to change filesystems in twrp?
please shre any ideas with me, i appreciate your help. My ohone is now bricked for nearly 24hours... I have no backup phone.

Click to expand...
Click to collapse
So if i go into twrp/wipe/advanced
select system + repair r change filesystem it says:
Size: 2929 MB, Used: 2597 MB, ext4
select data, ".."
Size: 113661 MB, Used:0 MB, ext4
I can Repair System , but not data.
data: it says /sbin/e2fsck -fp /dev/block/mmcblk0p44 process ended with error: 1 unable to repair data.
EDIT:
I tried to format every partition;
chache, userdata and system format fine,
but boot cant be formatted; it report error: "Formatting is not supported for filesystem with type ' '."
is my boot partition broken?

Lenovo Tablet 2 1050L boot failure after attempted root

hi - I hope someone can help me. I have a LTE enabled Lenovo Tablet 2 1050L which I attempted to root using the instructions given here ... https://forum.xda-developers.com/thinkpad-tablet/general/how-to-root-yoga-tablet-2-t3251571 ... but I have managed to brick my device. I successfully installed SuperSU but then read that Magisk was better and tried the same procedure with that but it didn't work. Now when the tablet starts up, I get a message which says ... "EFILINUX ERROR [android_image_start_buffer:737] boot image digital signature verification failed : 0000001A" which appears over the initial Lenovo splash screen. I then get to the Android system recovery menu but I can't get the table any further than this. I have tried wiping data / factory resetting but this does not work.
I can boot the tablet into recovery mode using CWM or TWRP but I have no idea what to do now. I guess I shouldn't have messed. I hope someone can help - I've tried the official Lenovo forums but no one has answered in a week.
Kind regards

I've downloaded this ROM ... lenovo-forums.ru/files/file/1074-yoga-tablet-2-10-yt2-1050l_s100192_151119_row_los-50 ... and flashed this onto my tablet using the Intel flash tool and everything seems to be back up and running.
Can someone confirm that this is safe to do? Can I trust this ROM as it's not from an official source?
Thanks

G900F Restart loops

Hello everybody
I'm having this random issues with my Galaxy S5 G900F (Klte) with custom and stock roms.
Boot loops some times (System or Recovery)
Freezes at Logo or booting system or booting recovery.
Spontaneous reboots on recovery or system, at start or sometime later.
Some times it reach the PIN screen and sometimes not.
Some times it works for hours and some times it is rebooting all the time.
It happens from some days ago when I did a restore from custom rom backup.
It was taking a long time booting to system (more than 1 hour) so I removed the battery.
When I tried to start again the phone was not working well. (Just rebooting all the time)
I tried to solve it by flashing my previous used Stock Roms with Odin v3.09 with the result = <OSM> All threads completed. (succeed 1 / failed 0)
KitKat - G900FXXU1ANE2_G900FOXX1AND3_G900FXXU1ANE2_HOME
Lollipop - G900FXXU1BOJ1_G900FPHE1BOJ1_G900FXXU1BOJ1_HOME.tar
Marshmallow - G900FXXS1CPG9_G900FPHE1CPE3_G900FXXU1CPC9_HOME.tar
I also tried with custom Roms: RR pie, Bliss 12.7, Crdroid...
Sometimes I'm having errors while flashing custom Roms but sometimes everything be correct.
I also tried repairing, wiping and formatting every partition to ext2 and ext4
For some times I'm having problems wiping and formatting some partitions (randomly): unmount partition or no such file or directory...
I also tried with Original recovery and TWRP 2.x, 3.2 and 3.3 with the same results.
And also tried with and without SD and SIM
I don't know what more can i do. Some idea would be nice.
Aditional info:
My battery only have 7 months.

Is there any way to full clean all the phone partitions memory or any else?
Is Odin cleaning the phone during the installation of a new Rom or it is leaving some untouched?
How is posible that after install a Stock Rom with Odin with success end the mobile being unstable?

I'm doing a lot of tests because I don't understand the cause of my phone is unstable, but I'm learning a lot trough internet.
Some of the tests I'm doing are having this unespected results: (I could update this)
Boot loop entering to recovery mode
Cause: Unknow
Solution 1: Some times works better when I maintain pressed Vol+ and home until the TWRP screen si shown. (But not allways)
Solution 2: Some times I need to remove the battery, wait some minutes and try again after before entering in recovery. (Some times I need to repeat the proccess)
Boot loop entering to system
Cause: Partition system can't be repaired and shows "unable to mount partition" error on TWRP (May be the files or the partition is damaged or lost)
Solution: The only way I found is enter in recovery mode and clean system/dalvik/cache then install the Rom again. (Don't need to wipe data if it's the same Rom/Gapps)
Cause: Unknow
Solution: Sometimes the mobile enter to system after some tries

I also want to share some knowledge with the people that are looking for solution of similar problems and they found this post.
Some usefull guides I found: (I could update this)
A nice guide about Odin: https://pakfones.com/what-is-odin-and-how-to-use-full-guide/

A nice program to get 4 part firmwares (SamFirm): https://samfirmtool.com/samfirm-v0-5-0 (The guide in the same site. )
Nothing new but , how to flash 4 parts firmware: https://rootsamsung.com/flash-samsung-stock-firmware-4-files

Something new, What is Combination Firmware?: https://combinationfile.us/what-is-samsung-combination-file-firmware/
Remove the space on URLS between droid and views.com
I don't see any diference between 1 part and 4 part firmware.
I think the Combination Firmware is only a little versión of Android (not much useful to fix nothing)
The same tools inside Combination are also on Development options in every Rom.

I will edit this post to not spaming the forum with the news.

But nothing really special, the phone continues restarting.
Testing 4 parts Firmware + PIT + re-partition + NAND Erase All
Nothing new, same reboot problems booting system.
At this point I have less reboots entering in recovery mode but:
Sometimes i have errors when I install custom Rom (E1001: Failed to update system image. and Error:7)
Stock roms boot loops everytime while booting system. (1 Part Firmware, 4 parts, with or without NAND Erase and PIT)
Custom roms like Bliss 12.7 works some times but without gapps.
I can't install Gapps now because errors / freezes at recovery.
Since the latest Stock Firmware installation I have more problems:
Black screen after Samsung logo.
More dificulties to enter on Recovery
Cannot solved by flashing any Stock Firmware.
Hardware buttons are good, and is not problem of overheats. (Works bad also in a cool state)
Going to SAT next monday.

T580 wifi version errors in recovery mode

I've been flashing phones/tablets as long as I can remember. I'm getting partition errors when I do anything with the tablet in recovery mode. I have the latest version of TWRP installed from a few days ago. The errors show partion problems as I see the following as soon as I start any wiping process or installation. The error below is an example of one of the errors. Any ideas? I have 2 of these tablets and I see 2 sdcard folders (sdcard, sdcard2).
error opening : '/external_sd/app/~~/yb_DpAd676L1_CbU4IeU6_g==/com.fingersoft.hrc2-GeAAkrpCUY8bu00W5KPyeA==/base.digest' (no such file or directory).

Very strange, after reformatting the sd card and insert it. It appears to have cleared up the issue.
