Had a TWRP backup of my 2063 ROM (Russian), tested it by restoring and all was well. Installed and tried out 2 custom ROMS ( Bliss, MSM Extended ), wanted to return to original Realme 6 Pro ROM; after wiping cache, formating data, tried to restore with my good TWRP backup and the dreaded "extractt TarFork() process ended with ERROR:255" appeared near the end of the data partition. Unfortunately I do not know the full name/description of the stock ROM that was on the phone, so I am doing a trial-and-error method with, so far, 2 (both 2061 ROMS). Just boot loops are the result. Any Suggestions?
Used Realme Flash Tool to fix this. Had to use it twice, and the process worked well both times. Gave a donation, as it was a huge help to avoid more time-consuming methods, even if they are out there.

If you don't agree ... stop reading and move on...
Background: Our phone has access to so much personal information that its scary if it fell into wrong hands. The only way to fix this is to encrypt phone. I did lot of research and here is a working solution that works for me - try at your risk.

a) Tested with ROM Stock 4.4.4 NH7 Galaxy S4 M919/Jfltetmo by @ShinySide
b) Tested with ROM |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
c) stock recovery AT&T S4 works with M919
d) Philz/CWM custom recovery
Encrypting with custom rom
1) Assume you are on custom recovery. - Backup everything first. Create a nandroid backup
2) Do a full wipe and install one of the two roms linked above (I have tested with few other roms ... none worked). Start the phone and set it up the way you want. Install all apps etc.
3) ODIN Stock recovery. See #c under download above. Its AT&T stock recovery but works for me. You need to know how to ODIN - find out. Doing this wrong will permanently damage your phone
4) Start your phone and turn on encryption. You will need to set lock type = password and will need to connect to charger and have 80% charge.
- Phone will do blank and stay blank for 20-30 minutes. Do not do anything. Encryption is happening behind the scenes.
- You might have to do this twice or thrice if it did not encrypt first time. For me the phone went blank first time and after 25 minutes it restarted but device was not encrypted. I redid the same steps and worked second time.
- If you interrupt the encryption process (battery pull or power up) you will see error message (encryption failed, reset device)
5) If all goes well you now have a password protected encrypted phone with custom rom!!! Check in Settings -> Security
6) You may install custom recovery ... but I don't see the point because you will need stock recovery to decrypt
To install another ROM
1) Reboot into stock recovery, then wipe data and cache (this removes encryption).
2) install your recovery of choice and install ROM using recovery. Philz/CWM

How to Flash a rom on an encrypted Android phone (specifically this one, the I9505 SGH-I337).
The Problem: Once encrypted, you can't decrypt it easily. When encrypting the phone android will tell you you can only decrypt it using a factory reset. Naturally you assume it's talking about the "Factory Data Reset" option found in Settings --> Backup and Reset. But noooo, Android is lying through its ****ing teeth. Then you'll assume you have to wipe everything from your custom recovery mod (CWM, TWRP, or one of those). Wrong again! You'll get beautiful "can't mount /data" messages and more bull****. I read about a workaround that required installing the new rom using ADB, but I had ingeniously disabled USB debugging prior to wiping everything, so I only got so far with that option (plus it's tediously long if you haven't installed all the necessary software already and don't feel like bricking your phone because you made a typo in the command line). So, apparently the only other way to really format that partition free of its encryption is to use a stock recovery. So:
Short Version for Godlike users who know automatically how to do all this **** without any help (mimicking how most help posts are finely detailed on this site): Flash stock recovery, wipe everything, flash your custom recovery and install your new rom.
Long version for us mortals who don't know everything and haven't already downloaded already every single bit of software on earth:
Backup all the stuff you want to save. This process will truly wipe EVERYTHING. You can do it manually, or you can use an app like Titanium Backup Pro to help you (find it on Google Play Store). Here's a nice guide which recommends what to restore and what not to restore: http://forum.xda-developers.com/showthread.php?t=1480343
Flash the stock recovery using Odin. You can download a stock recovery from here: http://forum.xda-developers.com/showpost.php?p=49687791&postcount=3 It's the link called "I337MK2stockrecovery.tar.md5" In case you don't know how to flash it with Odin, this short guide will help: http://forum.xda-developers.com/showthread.php?t=1506697
In step 6 replace "recovery.tar.md5" with the stock recovery you downloaded.
Wipe everything from the Stock recovery console. This little ****er will **** up the encryption all those sissies couldn't touch. You're welcome. You boot into recovery mode from a turned off phone by pressing simultaneously the volume up key + the home key + the power key until you see blue text appearing in the top left corner of your screen.
Reinstall your custom recovery. In my case I had installed the rom BEFORE flashing in the stock recovery (apparently it works, you just can't boot because of the encryption), so I was able to boot into the new rom before I returned to my custom recovery. Weird. Anyways, I recommend CWM. You can pick it up from this link: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/jflte
For some weird reason they call the I337 version the "jflte" version. It's bonkers. Click there, and download the latest version that ends with .tar.md5. This version is upgradable via Odin, which we already used. Use the same instructions used as when you upgraded the stock recovery rom.
Boot into your recovery mod and flash your rom like you usually do.
A word about TWRP: it cost me many hours of work and I don't recommend it. Its website is outdated, and recommends using GooManager (which is no longer mantained) and doesn't work anymore for this. GooManager suggests using a new, different app, which doesn't have the option of installing TWRP. Then I tried using their TWRP Manager app from play store and the image file wouldn't download. Then I tried manually selecting the image file in TWRP manager that I downloaded from their site for use via the ADB method, and it bricked my phone... twice (using two different methods the app sugested). I tried so much because in theory TWRP has the ability to decrypt android's 4.4 encryption, but after looking at their github site I noticed it was filled with people's reports (including people with the S4) on how it wouldn't work decrypting squat. So I gave up, and installed CWM in 30 seconds.

The quote looks long however it is really very simple. To install another ROM

This has been tested working on |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
This did NOT work on a Touchwiz ROM by same developer
I have not tested any other ROM

I don't know if it matters too much or not, but the stock recovery you linked to is for the AT&T S4. A good rule of thumb is to never use Odin to flash anything not specifically for your particular device... In this case the M919.

I have tested stock recovery on M919 .. it works
Honestly im surprised its not talked about more since there is a big push for personal privacy when it comes to data. Encryption really is a pain in the ass to work with on android. Figuring out how to switch or update custom roms while encrypted will drive you insane. The easiest way is to just odin back to stock and start over, but that requires a computer anytime you need to flash anything.
I recently was trying out one of the 4.4.4 GPE roms and turned on encryption. It worked great until i started missing touchwiz and wanted to go back to HyperDrive TW. So the journey began...
First of all, i backed up everything to external storage since i knew everything on the internal storage would have to be wiped. I loaded the phone into recovery mode (using TWRP) and tried wiping, but all i got was a bunch of "Failed to mount" errors. Fine. Got the same error when trying to factory reset or wiping /system, /data, /cache, and anything else. Tried formatting to different file systems and then formatting back to the original but no luck. Fixing permissions didnt help. I just kept trying everything available multiple times.
Eventually it started wiping everything except the /data mount. Well... At least i could install new custom roms. Im not sure exactly what did it because i was just throwing everything at it. Anyways I got it to install, and booted into it. Nope.
Now it was saying I needed the password to decrypt the internal storage. It would detect wrong passwords fine, but as soon as i put the correct password in, it would allow me in, show the green android encryption picture, then blank screen. I thought it was just decrypting and setting up my rom but after a few hours my screen was still black and nothing was happening. Pulled battery and went back to TWRP.
I started wiping everything again and again and tried doing everything i could to wipe everything on the internal storage. Again, not sure what did it, but eventually got it all cleaned up and got a new rom installed and could boot into it.
The whole process probably took about 6-7 hours...
I dont even want to enable encryption on the new rom...

Yeah Encryption does not seem to work on TWZ roms. I tried on G Eye without luck.
I have updated op. Please check
Encryption will slow down your phone quite a bit. More battery usage + more CPU usage + slower phone = not worth it unless you've got some very private stuff you don't want being shared. Otherwise, 3rd party apps that lock a lot of files, can encrypt certain files, and hide others will do the trick perfectly well.'
Not trying to bash fully encrypting your phone, but I've tried it before and although I am very pro privacy, I had to eventually take it off due to all the extra hassle it created.
Don't know about slowing down. I am not seeing it. I feel differently about security.
Hello,
It all began that i just wanted to restart my Oneplus3 unlocked with lineage 15.
But then back in Lineage15 i wasnt able to use my pin anymore + it restarted after few seconds...
Afterwards i ended up in a lineage bootloop.
Ok, then i thought then i do a fresh flash with new lineage 16.
I tried to flash but it said i need to install new modem firmware for Lineage16.
I downdloaded the new 9.0.5 modem + firmware and flashed it from here : https://forum.xda-developers.com/oneplus-3/how-to/op3-flashable-firmware-modem-zips-t3816066
Then i tried to flash LOS16 again but it failed due to some errors on unable to mount some partitions (cache , system, etc).
So i thought i need to wipe or reformat them, as some people suggested to switch from ext4 to fat and back to reinit the partition.
I did this for at least system and internal storage. ( i learned that it was a dumb idea )
Afterwards i was not able to push anything anymore through MTP in TWRP, but i was still able to sideload or push images via adb.
Afterwards i tried to flash LOS16 or LOS15 via TWRP again but it always ends up to a "unable to mount /system (invalid argument" error at some point of the installation.
I thought: Okey maybe i go back to stock as i messed up the internal file system somehow, and go back to LOS afterwards.
So i flashed the stock recovery for nougat which i got from here: https://www.****************/2017/0...th-latest-oxygen-os-firmware-complete-unroot/
Then i tried to flash various stock Oxygen roms with the stock recovery, by using wipe + system reset + adb sideload:
4.02, 4.51, 5.08, 9.0.5
4.02 and 9.0.5 didnt run until the end.
Flashing 5.08 works but ends up in a black screen when starting it.
Flashing 4.51 works but when i start it i run into a bootloop ( 2 Dots circuling forever )
I also tried to use the 4.51 version to flash LOS again but it did not work out
I just tried again to flash 4.51 but it also didnt work out anymore. :\
So, what do you think i could do to get a working OS on my system again?
Did i do something on the installation of LOS or Oxygen ?
Can i use a backup from a friends Oneplus3_T to get a working system partition / full OS again?
Should i unbrick the phone by using one of various guides to go back to fully stock? I am kind of afraid of this, as some people describe some final brick in the threads which may be caused by modem firmware problems (Sahara issue). https://forums.oneplus.com/threads/guide-oneplus-3-3t-unbrick.531047/ or https://forums.oneplus.com/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/
Thank you so much, i kind of getting mad about it
@julledd
Backup from 3T seems like a bad idea.
You may have a hardware issue.
Your best bet is to use one of the tools available in the various unbrick guides. If one doesn't work, try another.
Best of luck!
Hi thx for your help!
i tried different unbrick tools (9.0.5 / 3.1.2 / 4.0.5) and after several attempts i get it flashed to the phone. But in the end it still ends up in a bootloop, either at the android logo or the circuling dots. Via Sideload i am also not able to flash a new OS. It always breaks somewhen >50%.
In very rare cases i am then able to go to the OS, but when i go to "About Phone" to unlock it for TWRP, it freezes before showing anything. I guess there is internally something broken which forbids it to show the internal state of the phone. Every boot is different, and i cannot see any system in this failure of my phone.
Do you have any more hint?
I am already at a point where i want to exchange the main PCB.. Is this possible for the Oneplus3? Can i also exchange it with a Oneplus3T PCB?
Hello there,
I've recently received my Redmi Note 5 back from warranty service. As much as I like the phone, one thing I always found really disappointing about it is that for whatever reason, it is, as far as I know, the only phone from the Redmi Note series that has Camera2 disabled by default, preventing me from installing GCam. Fortunately, I have found multiple tutorials on how to activate it. Since I've wiped my data before sending it, now was the best time to do some tinkering.
I've used my friend's laptop to unlock its bootloader and install TWRP (it refused to work on my desktop for some reason). the official TWRP web page warned me that the phone uses dm-verity, which is something none of the tutorials mentioned. After some further digging, I found out that should I mess with it, the phone would simply revert any changes, and to prevent this, I needed to flash a dm-verity disabler, such as LazyFlasher
Thinking nothing would go wrong, I decided to try flashing TWRP and deal with the system replacing it with the stock recovery later. All went as planned, and the phone booted into the custom recovery with no issues. It asked me for a password to decrypt the internal storage, which I don't know, so I skipped this step. The first thing I did was creating a backup.
I then tried rebooting, just to see if it would really revert the changes. It did, but it didn't go as smoothly as I had hoped. The system became laggy to the point where it was basically unusable, often freezing for more than 30 seconds after just opening an app. Not knowing what to do, I flashed TWRP back, this time with the dm-verity disabler. A tutorial on how to do this that I found recommended I wipe the cache after flashing the tool. I tried doing that, but the process failed immediately. I rebooted the phone, and the next thing you know, I'm in a bootloop. I've let it sit for a while, but even after some time, the system wouldn't start. Fortunately, I was still able to get back into TWRP.
I restored the backup I created earlier. This, for the most part, solved my issues, the system works fine-ish again (aside from an occasional lag, but it's not nearly as bad as it was) and isn't trying to replace TWRP with the stock recovery anymore, but I'm kinda afraid to tinker with it again. I'd really hate having to buy a new phone just because I bricked the one I have (and I didn't even get to flash the tool that was meant to enable Camera2).
What did I do wrong? Should I've formated the internal storage to gain access to it first? Did flashing TWRP without dm-verity disabled somehow mess up the system? Would flashing a custom ROM bypass having to disable it? I'm confused...
I've been trying to install one of the android 10 lineages on my wife's phone.
It keeps on bootlooping and by now I have tried so many combinations of twrp and restores, wipes, different roms and restoring the backup of an android 9 lineage.
The phone keeps bootlooping, sometimes in the "your bootloader is unlocked" message and sometimes in the lineage startup movie.
It even seems to bootloop in the twrp startup screen, but maybe it is just slow and my impatience is getting too high.
I've tried two different twrp versions as one gave an error in restoring a backup (I think the newest one gave the error).
Could it be that a backup made in the older twrp cannot be restored with the newer twrp?
I'm running out of options and may need to go back to stock, which is not the easiest path to take.
Oh, the phone was rooted when I made the backup, if that makes a difference...
Any thoughts?
If you backed up all partitions, then restore all of them and follow the steps to install...
Note: Before you restore the partition, make sure to wipe it, it ensures that nothing goes wrong...
So, I tried some custom roms out there it has caused some really odd issues on this device. The first one I tried was CalyxOs, then lineage, and Proton. All are good roms, but not what I am looking for. But somewhere along the way things got wonky to say the least. Now, I am not blamming any rom or dev for "breaking" my device. I flashed these roms knowing there is a risk, and the roms listed above work for others. I'm pretty confident, there is something I did along the way that screwed things up. Some of the issues I have ran in to:
Before I flash anything, I learned a long time ago, make a backup and transfer all data on sdcard to your pc.
I generally use TTBU. But recently, when I tried to manually drag/drop my sdcard backup to my device, not all files gets transferred over. Basically all the .apk.gz files. Which happens to be the core of the the backup for the apps.
I started using another backup program, oandbackup, which transfers fine. But my apps/data only gets properly restored about 20% of the time. I say 20% because out of 10 flash back to stock and restores, only 2 will successfully work.
When flashing the rom I have been working on, I use lingeage recovery. But what worked yesterday, fails tomorrow. My method has been, flash lineage recovery, flash rom, boot, test rom, flash back to stock, restore. However, it doesn't always work out that way. Sometimes, it will flash fine, I reboot back to recovery and flash gapps, boot system and the loops begin. Flashing a different kernel fixes the bootloop. Oddly though, the stock kernel booted fine on the last flash (mind you, no changes in kernel or rom code). There is a slew of roadblocks and walls I have slammed in to, but this is just to give you an idea as to what I've been trying to work with.
Now, after flashing a custom rom and then flashing back to stock, I always wipe data. But the most recent issue I have encountered, I flashed back to stock. I was on "b" partition. After the initial flash, it boots to fastbootd. Oddly, I was stuck in stock recovery with the little android guy laying on his back. I hit power then vol up and got in to recovery where I selected fastboot and the fashing process continued. After my phone booted, I rebooted back to bootloader, switched to "a" partition, rebooted bootloader, and ran the stock flash script. This way, in my hopes, I would get a fresh and clean flash all the way around. Again, the whole recovery thing happened again, and I resolved it the same way. But when the rom rebooted, bootloops which eventually kicked me back to bootloader. I switched to slot "b" and the rom booted, went thru setup and restored my data, but most apps failed. Luckily, the 1 game I cared about restored this time.
So, yesterday, I wanted to check out stock recovery a little closer, and see if I could use adb. When I tried adb pull <random file on sdcard>, adb did not connect. So, I tried to reboot. Unfortunately, I got stuck at the google boot splash. To recover the device, I had to flash my boot.img.
This morning, I set out on a mission to try and get things fixed back up. I know slot "a" is not bootable, so I figured I would start there. I went to stock images and instead of downloading, I used the online flash tool. nSince I was on slot "b", it flashed to "b" even though I choose to wipe data and force flash all partitions. I tried booting slot "a" but it failed. So, I manually switched to slot "a" and ran the online flasher again. Now slot "a' and "b" both boot successfully. Then I started restoring my sdcard. It is 4.2gb of data. Honestly, not a lot IMO. But it took an extremely long time to restore it. After restoring my sdcard, I ran oandbackup, but I only restored data for 4 apps, which was successful. Everything seems to be running smoothly, and I was able to flash a custom kernel, root, etc with no issues. I guess, when I flash the final beta of my rom, I will see if I got things fixed up or not.
As I write this, I can't help but wonder, what is the root cause of all these issues? One thing I thought of was my cable. I was using one of the usb cables for my oneplus 6t. I switched to the stock cable to test things. I wiped all my data from the sdcard and then restored it with the stock cable. Things went A LOT quicker 928 minutes with op6t cable/2 minutes on stock cable). Since I have things to do today, I have to put this aside for now. But I wanted to get everyone's thoughts and input on this. Have I done something terribly wrong along the way that has caused these issues? Could the cable I was using be the root of all evil in this case? Is this just that wonky of a device, that it has happened to others and a great deal of patience is needed when trying to work on the pixel 4a 5g?
