[Completed] Note 4 recovery capped

I am having some serious troubles with upgrading my Galaxy Note 4 SM-910P (Sprint). All was well in rooting, un-rooting, etc... I have the original 4.4.4 and the new 5.0 backed up and now I can't use anything other than the firmware the original firmware package through Odin. The problem started when I installed the [ROM]ViSiON-X N4 SPR 5.0.1 [Android L 5.0][N910PVPU1BOB7-R1][03-11-15]. It installed fine but when ever I was not watching it a problem occurred such as getting locked out of ny ext SD, or just plain un-rooting itself. It finally came down to it just kicked my device into download mode and would not reboot. I did used chains Odin root method and installed TWRP, which I can still do but can not flash or restore from TWRP or CWM recovery. It will take the firmware package fine and download the 5.0 update but always gets stopped from any other upgrade at recovery be it stock or custom. I have even used Kies to try and upgrade a few time. It will upgrade from NK1 to NK2 but still will not upgrade anything else past recovery. Every time I reboot I lose my WIFI password. After every boot it takes a minute for any network to be able to reach the device. It is paused until I re enter my WiFi password then it will say that Android is done upgrading and there is a toast message that says "device is set to factory mode some items won't work on this mode set device to user mode". Can someone please tell me how to set my device to user mode or erase what ever is lockled in my device between download and recovery. The issue I described with the device wanting to stay in download mode and how to handle it is described her http://forum.xda-developers.com/showpost.php?p=59372208&postcount=3 but as I mentioned I can't get passed anything that is not firmware through Odin. If I had to be locked in one version forever I would have preferred it be 5.0

I figured it out

I fianlly figured out the deal with TWRP not flashing.
The change between file systems is what TWRP won't flash.
To flash into the new, the old, or back up property check the file type.
Ext 2, Ext 4, F2FS, etc ...
To get recovery to load install from odin with auto boot disabled, remove battery, than vol + - menu and power.
the steps below..
1. Power off (complete) boot to download.
2. Load Odin, uncheck auto reboot, PDA TWRP. after it installs pull battery to exit.
3. Boot to recovery - wipe- advanced wipe -Repairor Change File System - Check System (go thruough each)
4. Repair and change each to the file type you want to flash
5. repair and or change the files for the zip you are going to flash
6. you have done all the rest before ....

Issue resolved, thread closed, thanks.

S7 in recovery boot-loop

Hi,
I just "slightly" bricked my S7 (SM-G930F), and I hope someone can help me. My first S7 (which had Superman-Rom installed) had a burnt-out USB port, so I got a brand new replacement. I made a TWRP backup from the old one and installed that on the new one, but I think I made 1 (or even 2) critical mistakes here: I installed TWRP with ODIN on the phone directly out of the box without starting it once, so I never activated the OEM unlock. Furthermore I restored the backup including the EFS partition. The first start-up went fine, just I couldn't unlock the screen (password not valid). After restarting the phone I got the message "Custom binary locked by FRP lock". Using Smart Switch's device initialization, I could get the phone into download mode again and flashed the stock rom (G930FXXU1DQEI with VD2 carrier) via ODIN. But that got me nowhere, after showing "Installing system update" I just got a screen with "No command". Then the phone rebooted again and went directly to the recovery, showing "Successfully verify for dmverity hash tree". Any attempt to restart the phone just shows the Samsung boot logo two times and then I'm back in recovery, where it then shows "No Support SINGLE-SKU, Supported API: 3, dm-verity error, failed code: 0x02". Trying to install TWRP again just triggers FRP lock. I tried both Smart Switch and ODIN several times in different orders, but nothing works.
Here the timeline again:
1. TWRP-Backup old phone (Superman-Rom)
2. First start new phone directly to download mode, installing TWRP (no OEM unlock)
3. TWRP-Restore new phone, EFS included
4. Rom starts, lock screen password not valid
5. Restart
6. FRP lock
7. Smart Switch
8. Stock rom via ODIN
9. "No command"
10. Starting to recovery, dm-verity ok
11. Restart
12. Starting to recovery, dm-verity error
13. Restart
14. GOTO 12
15. ???
Another interesting thing is that at the first start into recovery after flashing the VD2 stock rom, I also get the message "# MANUAL MODE#, Appling Multi-CSC, Applied the CSC-code : DBT, Successfully applied multi-CSC". As I downloaded the VD2 rom, why is it setting the csc to DBT?
Anyone who can help me break the loop?

Hi
Main issue I see is:
Install EFS partition from one phone to the other.....lets hope you did not mess the IMEI , EFS are device specific.
OEM unlock maybe an issue but Odin flashing should solve it ( most of the times)
You said you flashed with ODin , what file you used CSC or home_csc? if you used CSC did you selected re partition?

Is there a way to restore the original EFS partition? ODIN has the option to clear the EFS, but I could not find any information on what this does, only "stay away from it!!!!!".

I tried both, but mainly CSC to also do a factory reset, and I also tried to repartition. Only thing I still haven't tried is "Nand Erase All", because "stay away from it!!!!!"

There are ways to restore the EFS , the question is do you have a copy of the original EFS??
Do not use option in Odin you do not know about.... re partition is known did you use it?
check this info regarding that

Yes, I already tried to repartition. And no, I don't have a backup of the original EFS, I accidentally restored it because I overlooked that is was checked in TWRP (or just checked everything that was there without really looking?).
Regarding Odin it's just sad that nobody seems to know what some of the options really do, maybe some combination could help me.

https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
or may have to take it to a service shop ( a good one) they have special boxes with special options to fix this kind of problems

Thanks for your help Max, but it seems I have to pick your last option and search for a service shop. I downloaded the latest available combination firmware, but after installing it the phone gets stuck on the boot screen with displaying "ASV TBL VER = 10; ASV TBL VER2 = 0; NAD: PASSED; NAD ACAT: FAILED; RPMB PROVISIONED" on the top. Reverting to the normal firmware brings me back to the recovery loop. The problem is also that there seems to be no combination firmware for Nougat, all the files are for Marshmallow. Not sure if this is the reason that the phone gets stuck, but I think it likely.

PROBLEMS in installing TWRP and root (20a)

spent the last 3 weeks ( NO LIE ) trying every method under the sun to get my device rooted
easy recowvery
Hard Recowvery
manual ADB and flashing img
tot updates
kdz downgrades
basically everything
im not sure what else to do if its even possible at this point
Device details
tmobile locked LG G5 (h830)
OEM unlocked
its on 20a firmware ( coming from 20i )
ive rooted and installed twrp on may phones so i have a vast knowledge of these things
a few observations are
phone seems like its rewriting stock recovery on each reboot
fastboot won't accept any commands, i get "writing 'recovery'...FAILED (remote: unknown command)"
both hard recowvery and easy recowvery work up to the part of twrp install then it reboots to nothing
FINAL NOTE
im wondering if t-mobile is blocking the fastboot commands since im on temp unlock via device unlock app
if thats not a thing idk whats wrong im hoping one of you great minds can help this poor soul

Anyone?

Did you check oem unlock in developer options

thanks for replying ,
yes i did
its greyed out now but its been off
the fastboot commands says its unlocked as well

Did you make sure to download the recovery image and put in the root directory of the device storage and rename it recovery? If not then non of the recowvery methods will work. Also twrp needs to be the newest image. When using easy recowvery you should hit option 5 and enter then option 7 and enter and then option 0 and enter then option 2 and enter. Select y for yes when prompted and let the program do its thing. You should be prompted to boot into recovery at the end and it will go into tarp recovery. Hit cancel when it asks for password. Then go to wipe and format. After formatted, you need to install no-opt enc or root and then you're done. If you want to update all you have to do is get latest firmware from this forum. Also' if you update you need to also re flash no opt enc or root again and I also delete recovery from boot.p file in recovery. Should be good to go!

providing an update
Ive just tried everything listed in you post specifically and failed , so i tried like 2 more time ,
it reboots into stock recovery so still no TWRP ,
boot loader is unlocked , cause i just checked again , and its still not accepting any commands

Adb flash commands do not work for the lg g5... You have to root with either easy recowvery or hard recowvery. You have to be on 20a firmware.

thanks for reply;
none of those work for me either, I've been trying all this time
it says its successful in deploying commands, but when it restarts I see the LG logo two times, then it boots back up
( i assume its rewriting recovery there )

Can you explain the exact process you are trying? It is kinda hard to diagnose the issue without knowing the full process you are trying. I have rooted several lg g5 phones with the autorecowvery tool.

I had the same issue after returning from 20k to 20a. I didn't have this problem doing the same from 20f. T-Mobile might've introduced some security kink at 20i that sticks across updates. I was only able to flash twrp after flashing 20a with UPPERCUT to enter LGUP, booting into 20a, allowing debug in developer options, then running easyrecowvery with verification disabled (press 5 for advanced options, then 7 I think, then 0 to return to main menu, then 1 or 2). With verification enabled, easyrecowvery will just take you to the non-existent Android recovery screen and leave you there. I think that's where you're stuck??

well lets use Autorecowvery for example
ive exhausted all options there and Ive gotten the success messages , does its fancy restarts and success messages all around , but when it restarts to install the "no-verity-opt-encrypt" it reboots and comes right back to android . ( note it reboots 2 times at this point , so i know its rewriting stock recovery )
see below
https://ibb.co/eq5ctR

It seems like you have a recovery flash. Have you tried adv reboot recovery? If not then you need to try that. You can also use hardware combination to get into recovery. You have to select yes both times and it will reboot to recovery. If it doesn't then start over with the auto recowvery. Also, it is very important that you download twrp and copy it to your internal storage on the root. Also, once it is there you have to name it to recovery. Don't use the .img when renaming it because you end up with recovery.img.img... Sometimes it takes a few tries on the recowvery method... Hope this helps!

well ive used
- "adb reboot recovery"
- hardware keys ( whenever i do this it wipes the phone ) , so i wont be trying that much cause i have stuff on it now , phones not encrypted tho
ive tried all 4 versions of twrp and renamed them all , countless times ive tried everything ive searched and read

When you first get into TWRP for the very first time, I believe it is a must to "FORMAT DATA" before you flash supersu and 'no-verify' zips

I know this might sound silly, but have you extracted the twrp file and then renamed it to recovery? Have you tried downloading on your phone and then extracting it on your phone and then renaming it? After I looked at the image you shared it seems like the flash seems to have an error and the only thing that makes any sense to me is a bad download of twrp or an unextracted version. I've ran into that error before and it drove me nuts until I figured it out...

ive tried both your suggestions plus more
copied to the phone and renamed
downloaded on the phone then renamed
dowloaded on pc and renamed then copied to phone
used adb to push and rename to phone

still having challenges with this
do you think its a dead case guys

OP isn't the only one with this hair-pulling problem...I too downgraded a new H830 from 20M (? I can't remember which one exactly since I've LG-Uppercutted 20A and troubleshooted this constant problem so many times now)---I get the exact same error as OP, also with the highly suspicious 'greyed-out OEM Unlock' (in the Developer Options of the Settings).

Any root for SM-J327W yet?

Hello, I was searching for a root for my "new" Samsung J3 Prime (SM-J327W) that I got from my sister. I did the OEM Unlock and in ODIN Mode, it says that it's also "FRP LOCK : OFF". So far, CF-Auto-Root didn't work and all TWRP images, that I found, wouldn't even download on the device . I tried images for the "T", "P" and "U" variants also. The "P" one, lead to bootloop (I recovered stock rom since I got it). So is there any root for this device? It's on the latest versions of firmware and Android available for it.

Did you find anything for the J327W yet? I can only find ROMs for the 320, 327P and 330. I've been having very erratic battery life for over a year. It started after a factory android update. Sometimes my battery life will drop from 70% down to less than 5% in a minute. I've done a factory reset, cleared the cache and replaced the battery but nothing has helped. Trying to put a new ROM OS on this POS is my last hope.

I think you'll need a battery replacement at this point... I did build a TWRP ROM myself for my popeltecan (code name of J327W in Canada apparently) but, according to a TWRP Builder Developer, my device might have some kernel issues with TWRP so I can share my ROM but I am not sure it will work on your device. Do you have your stock ROM in case?

Here is a GDrive link to my recoveries, there's the stock and the twrp one but be aware that you need all the ROM if there is a problem with the twrp (that means stock : BL, AP, CP and CSC). But you can use the stock recovery to build a device tree.

Replaced the battery about 3 months ago but it made no difference. I have some vacation time coming up so will have a little more free time to look into things.

Maybe a factory reset would be a good idea to try. If you want to try my twrp recovery build, you'll be wiping your data anyway. I highly suggest you to get the full stock rom since even just getting back the stock recovery could end up with a weird sort of corruption (like duplicated or unknown options inside the Settings app, or at least I experienced that). I am not responsible if it breaks anything, you were warned to get your precautions such as getting the stock rom.

hi if your still looking. i looked into it and the j327u twrp does work on j327w. i had the same problem trying to gain SU access with the other image files for j327w i had to use magisk zip and install it from twrp menu. had to format data and mount system in twrp.

twrp j327u does work but i could not get supersu or magisk to work, my build is J327WVLS4BSK1 with 8.1.0 oreo. i'm not sure there's a way to get past dm-verity using the boot patch by asphyx in the TWRP threads or the universal dm-verity workaround by zackptg5.
i first flashed twrp j327u using odin, ran up against dm-verity when running supersu. both MikasuX14 and another twrp j327w version i found would also flash and load, but the touchscreen wouldn't register my input. cfar didn't work either
sfirmware (website) has workable firmware for rev 4 j327w builds in case you need to recover your phone from soft brick - i could get my build's firmware to flash using the patched odin 13.3.3 version found on this site

heres what i did. i soft bricked, bootlooped and had to flash firmware from sfirmware a few times to get it to work
i used a twrp for j327u i found on a another similar thread on this topic. i flashed it with odin.
once inside twrp menu i went to wipe menu, i hit format, then back to mount menu, checked boxes data/system (previously data or system wouldnt check off before formatting data).once data and system were mounted i then
plugged phone back into computer while in twrp menu. the phone showed up as J327u cut/paste the latest magisk .exe into the internal storage of j327u (on computer) . i then on twrp menu found and installed magisk exe finally got it to properly install magisk i then in reboot menu hit system and reboot.
the phone restarted after awhile like it was factory reset but once i set up the phone magisk apk was already installed and root access was available. hope this helps.

so i've been busy for a long while before looking back into this. I will try again with the J327U rom. Right now, i struggle to find stock roms of the J327W because i flashed a not working twrp apparently and it locks my boot.

The J327U TWRP didn't work for me. Though, twrp itself works but i cannot get the system to boot and i cannot get to root it, no matter what i tried, i ended up in boot loop.

I managed to root this phone without TWRP. I used Linux tools to do this so I'm not sure if it could work on Windows.
Requirements:
Stock ROM for your phone (I used samfirm.js to pull it from the Samsung servers but downloading from sammobile.com works too)
A way to extract zip files
A way to extract tar files
Heimdall flasher (https://www.glassechidna.com.au/heimdall/)
Magisk Manager APK
An Internet connection on your phone
A compatible USB connector for your phone
Of course, a SM-J327W running the stock Android firmware
Obligatory warning: This WILL void the warranty of your phone and permanently trigger the warranty void flag. It also WILL cause a factory reset, so back up all your data first.
Bear with me, because there are a lot of steps. This will take around 15 to 30 minutes.
You will need to download and extract a stock ROM for your phone. Make sure that you download a ROM for the SM-J327W and not another model. Also make sure to download the latest version available.
Stock ROMs usually come in a zip file containing a few tar.md5 files. You will only need to extract the one that starts with "AP" for this procedure.
Step 1: Extract the tar.md5 file that starts with "AP" from your stock rom.
Step 2: Open the tar.md5 file in an archive manager. You may need to remove ".md5" from the end of the file.
Step 3: Extract the boot image (boot.img) from the AP file.
Step 4: Upload the boot image and the Magisk Manager APK to your phone. You can use ADB to transfer the files. For example:
adb push boot.img /storage/emulated/0
adb push Magisk-v22.0.apk /storage/emulated/0
Step 5: Open the files app on your phone. Navigate to the internal storage and tap on the Magisk APK file to install it. You may be prompted to allow installation from unknown sources.
Step 6: Open the Magisk app. It should say that Magisk isn't installed and it shoulld say "Yes" beside "Ramdisk". Tap the cogwheel icon in the top-right corner.
Step 7: Due to a bug in Magisk, you need to install version 21 instead of the latest version (v22). Set the update channel to "Custom Channel".
Step 8: When prompted, enter the following URL: "https://raw.githubusercontent.com/t...d863d3a15c6a2276b1061a280ece80ed7/stable.json" (Without the quotes.)
Step 9: Now it's time to patch the boot.img file. Tap the button to install Magisk and select the option to patch a file. When prompted, navigate to the internal storage and select the boot.img file that you transferred previously.
Step 10: Magisk will patch the file and tell you where it saved the patched file. Transfer the patched file to your computer. You can use ADB for this, for example:
adb pull /storage/emulated/0/Download/magisk_patched_XXXXX.img
Remember to replace the Xs with the the random characters that Magisk added to the file name.
Step 11: Reboot your phone into Download mode. You can shut it down and then hold the power, home, and volume down buttons at the same time to enter Download mode or use ADB: "adb reboot bootloader"
Step 12: A warning may show about the dangers of installing a custom OS. Press the volume up key to continue.
Step 13: The screen should now show "Downloading... Do not turn off target." If your phone isn't already plugged into your computer, plug it in now.
Step 14: Use Heimdall flasher to flash the patched boot image. For example:
heimdall flash --BOOT magisk_patched_XXXXX.img
Again, replace the Xs with the random characters that Magisk added to the file name.
Step 15: After a few seconds, Heimdall should report that the flash succeeded and your phone will reboot. It may take longer than usual. Leave it to do its thing and DO NOT pull out the battery.
Step 16: Your phone will show a notice that unauthorized changes have been detected and will prompt you to factory reset it. Press the button to perform the factory reset.
Step 17: Set up your phone as if it was new. It's not rooted yet, but you're really close if you got so far.
Step 18: Once you reach the home screen, upload the Magisk Manager APK to your phone again and install it like before.
Step 19: Open Magisk Manager. It will show that Magisk is installed and may prompt you to reboot to complete installation. Do not update Magisk to v22 or you will lose root access and you will have to flash the patched image again.
In the (very unlikely) case that your phone doesn't boot after flashing the patched boot.img, you can simply flash the original boot image and it should be fixed.
CONGRATULATIONS! You just rooted your SM-J327W successfully.
I also managed to port TWRP to this phone with the touchscreen working using the kernel from a recovery image for the SM-J327P found here: https://forum.xda-developers.com/t/...-1-samsung-galaxy-j3-emerge-sm-j327p.3573607/. All the partitions are mapped correctly. Due to a bug (presumably with the kernel), the data partition can unfortunately only be mounted read-only. However, this shouldn't affect being able to flash zips on your phone and you can insert an SD card to write backups onto. In the future, I may port CWM recovery to this phone using the stock kernel to be able to mount the data partition read-write.
You can find my custom recovery attached to this reply.

Follow up: It seems that the bug that causes Magisk to fail is fixed in the latest version (v22.1.) As a result, steps 6-8 in my previous post are unnecessary.

Here is a GDrive link to my recoveries, there's the stock and the twrp one but be aware that you need all the ROM if there is a problem with the twrp (that means stock : BL, AP, CP and CSC). But you can use the stock recovery to build a device tree.

S7 lost /efs and with it imei on bootloader v8 - chances of repair?

I have a s7 G930F here in Germany were i lost /efs due to a wrong backup overwrite.
The phone was on stock oreo with bootloader 8 now is on lineage but ofcourse mobile data / calling wont work without propper imei or efs.
I tried to flash a factory image / combined image but that does not go through with odin as the phone checks boot loader versions and i havent found an image with b8 as a bootloader version which would restore my/efs.
What are my options?

You just need to flash the latest G930F for Germany. The firmware code is DBT, it's unbranded so no netweork provider bloatware.
I've attached Samfirm tool. It gets the latest firmware straight from samsung servers version 8.
1. Unzip
2. Run application as admin
3. Check auto box
4. SM-G930F in Model box
4. DBT in Region box
5. Check Update
6. Wait to finish
7. Flash files with Odin
8. New Phone.

I followed your instructions and downloaded Firmware.
After flashing the phone reboots, displays that its erasing and after another reboot stops at the screen with the yellow exclamation mark and displaying "no command".
From there it only loops: reboot -> installing system recovery displayed for a very short time -> no command.
I since flashed multiple times and got the same result everytime. I flashed BL AP CP CSC (both CSC and home CSC yield same result) . Odin shows no errors.
Firmware is G930FXXS8ETC6

Alright i think i resolved part of the issue as follows:
* i flashed the complete stock firmware as described above
* After flash was done i rebooted again into download mode and installed TWRP as recovery via odin
* I then booted into TWRP and copied the "no-verity-opt-encrypt" in the latest version to the phone
* The zip of "no-verity-opt-encrypt" i then installed with TWRP.
The phone booted up. Factory Samsung Android works but the imei is still shown as empty / unknown.
Some guides suggest to flash a factory combination image but i can not find one for bootloader version 8 which is on my phone.

Yes sometimes this happens, try a different firmware like United Kingdom BTU.
Does Odin say Pass?
The updating and erasing screen is normal after flash just leave it.
Once the phone boots on BTU you can either change language to German or flash DBT again.
It's worth checking / reinstalling Samsung drivers. Use different USB port. Odin should be version 13.
As long as you can boot into download mode the problem is fixable.

Thanks for your advice.
I will try the BTU firmware later. Just to check we are on the right track: If i understand you correctly you are saying the lost imei will be "fixed" by installing either the BTU or DBT stock firmware via odin?

Installed the BTU version. Same behaviour. The System does not start and hangs on the same position.

OK it sounds like the BL info on the EFS is missing or corrupt.
Just try one more thing before trying to repair the EFS.
Flash firmware again with Odin but uncheck "auto reboot"
When passed in Odin disconnect phone.
Hold volume down+home+power. As soon as the screen goes back move your finger to volume up while still pressing home +power. You want to boot into system recovery. It may take a few attempts.
Once in system recovery, wipe data/factory reset and reboot phone.

Managed to get into Recovery directly after flash. But recovery is not loading fully and is outputting some text like :
HTML:
failed to open recovery_cause /No such file or directly)
Blob verificatio failed 255
failed setting up dirty targets
failed to mount /system (bad file descriptor)
...
Any chance of reparing the efs? Someone here messaged my and told me i would in PM that i might need to connect to some server software to get efs back.
Any idea is appreciated

Anyone offering money to fix or connect to a server is a scammer, stay clear.
To repair the EFS you have to get the stock firmware back on there or flash someone esle's EFS back up file. You can buy a damaged S7, install TWRP, back up the EFS to the SD card, put that sd card in your phone then restore the efs. Your phone will then take on the identity of the phone the EFS file came from. Effectively you will have a new IMEI number and mac address. As long as the donor phone is not registered on the network your phone will work fine. You cannot have two phones with the same IMEI registered on the network, both will be blocked and black listed. Obviously the donor phone must be exactly the same model as yours.
However the method below should be tried first.
The error with the text "failed to open recovery" means the phone cannot find the partition where the stock recovery file is located.
Now to solve this we can install TWRP with ODIN and that will provide a way to install the stock firmware in .zip format direct from the sd card using TWRP as the recovery method instead of the inbuilt stock recovery which cannot be found.
You should then be left with a phone which has a restored EFS with your original IMEI and other data with TWRP as the recovery tool.
Which ever method you choose TWRP must be installed first.
