TWRP Restore Error 255 - One (M8) Q&A, Help & Troubleshooting

Team,
I just recently bought a Google Pixel and was attempting to transfer my contacts and messages and stuff from my HTC One M8 to my Google Pixel. However, my HTC One M8 was still on KitKat (4.4.2) and would not work with the transfer tool. So then I said let me take a TWRP backup of my phone before i start attempting to update it.
I attempted to download a rom to flash via TWRP but it did not work so I naturally tried to restore back to the TWRP backup I took.
Except now everytime I try to restore the backup I took all I get is extractTarFork() process ended with ERROR: 255
I have attempted to google all day with no luck.
Anyone dealt with this and have resolved it?
Thanks!

Did you try updating TWRP? I had something like this happen a few years ago with my S3 and updating my recovery fixed it.

yep, I had updated to twrp 3.0.2.0...still no luck
there has to be a way to fix this

so now even more weird. I downloaded Titanium Backup to try and extract from my TWRP backup, and nothing is there!
how the f is that possible!? does this mean my data is forever gone?

NoCall log, you should backup your calls with CALL LOG BACKUP & RESTORE apk from play store.Messages,you should backup with SMS BACKUP AND RESTORE apk from market(witch also can make a backup of all your sms/mms & call log!!!),so it's an one app for all.Both app make folders on your internal/sd memory that contain files selected by name and date,and you can just transfer this folders from M8 to Pixel and download those apps from playstore on your new Pixel phone,and restore calls/sms..About Titanium restore,isn't M8 ARM phone and Pixel is ARM64(or x86,I'm not sure)?so you can't restore those apps in TB cuz they're different versions with diferent screen DPI,and I suppose they won't work or TB gives you error cuz of that.You can only restore data from TB ,and it's very probable that some of those "restore' s" will give you problem due thing I sad in upper text and also cuz of big difference in Android versions(4.4>7.0+).
I hope you understand what I try to say,English is not my language,and I'm just trying to help you.I didn't by Pixel yet,I plan to,and this is what I would use in mind doing those transfers and restore procedure.
I had LGG4(ARM64),I transfered all my TB folder from M8(ARM),and when restoring ARM>ARM64 ,many of them force closed or mail function.But ONLY data restore allways worked on already installed app.
And about your error and problems on m8 with TWRP,yes try with some other and maybe older versions of TWRP(if m8 is on 4.4.4 ,then maybe latest recoveryes have problem to do backup and restore.In the end,try to flash stock RUU for your version on it,then TWRP+superuser,to try to fix all.BUT BEFORE Ruu Move all your TB and other data from internal memory/sd to computer or some other external drive-in case you lost or overwrite your data on phone.
Maybe someone will point you in right direction,maybe someone already had that problem.

Thank you for your reply; I wish I had asked before attempting.
Here is what I see from the bootloader screen in case it helps --

I took the full backup of my M8 using some version like TWRP v2.8.0.? I tried to restore the backup and it kept throwing me that error. So I said, lets try to flash the latest version of TWRP and that is what I did. I attempted restoring through the latest TWRP but still I get the same error. I have also tried to extract the backup using Cygwin with no luck. Titanium Backup also does not see it as a valid backup.
I am still on Android 4.4.2 (I had a backup from 2014 I was able to restore to in the meantime and is rooted).
The only place the data from my M8 is, is in the TWRP backup file which refuses to restore. All data on the phone was formatted and overwritten as I tried to flash a newer rom on it with no success. I have not tried to restore the data to my pixel and will not do so. All I need to do is restore the M8 backup to the M8 and try the methods you listed but I cannot get past this TWRP error. Or, get the backup to extract properly without throwing errors so that I can get the appropriate .db files from within
I am sure there is a fix involved with TWRP or is my wishful thinking sore out of luck?

I had this problem and it took me two days to resolve it. I had a good backup and I know it was good because I had used it several times and it worked. But then after doing some system installs I got the error 255. I tried several things to fix it and nothing worked and I really did not want to lose my backup. What did work for me was to use TWRP wipe function to FORMAT the phone. Wiping or factory reset did not work. I lost the contents of my internal SD card but I was able to transfer most to my external SD card. You could also connect the phone with a cable to a computer and use the pull command in ADB to backup the contents f the internal SD card. Given the choice between losing the SD card and the data files I come to lose some of the SD card. Anyway, a FORMAT worked when nothing else did. I read that this error is caused by a lack of space. When I checked the log it seemed that the restore was failing with a particular file which misled me to thinking I had to remove the corrupt file, but since after the format I was able to restore without any problem, it would seem that there was no corrupt data. Hope this helps someone.

[Q] Recovery not restoring data

hi, i need help restoring my backup in cwm 3.0.2.8.
The system partition restores fine but none of my apps or anything get restored. I've tried different versions of cwm and none of them have worked. I know i can just restore my apps with my backup or titanium but i shouldnt have to and i forgot to before i made the backup.
It doesnt even restore any if my contacts, texts, etc. It seems like its just restoring the rom with what ever mods and tweaks i had applied. This has happened with multiple roms so i reckon its a fault with cwm. Also when restoring just the data in cwm it doesnt say "Restore complete!"
Anybody got any suggestions?
Anybody got any suggestions?
How are you restoring your ROMs?
Your contacts should be backed up with your Google account.
They are backed up but cwm should restore everything. After i restore it asks me to login to my google account, select my time-zone, etc.
Im restoring from recovery.
It seems like cwm is crashing while restoring my data partition because the screen goes black whilst still showing the rom manager icon and it goes back to the inital screen of recovery like i just booted into it.
Have you checked your SDcard for errors?
There are hundreds of people who use ClockworkMod Recovery without issue. (excusing 3.0.2.5)
Could be something as simple as a couple of bad sectors on your card.
I recently formatted it before i made the backup, how would i check for any more errors?
Try HERE. Its in Russian. So you'd need to visit via Google or use Chrome.
I downloaded but i dont have a clue how to use it
Read through the manual.
Or you could follow this guide HERE, I'm pretty certain that the first tool would be more accurate.
I tried the russian one but i got access denied so im doing the windows method. If none of this works, is there a way to manually extract the files from the .img file? I mainly want the data from my apps because i hav around 300
How are you connecting your SDcard to your computer? I just ran a test using ,
Code:
flashnul G: -T
It worked fine, that was connected via USB cable with the card mounted as a drive.
No problems which I'm pretty pleased with, now just to transfer my data back.
I forgot to run CMD as admin, its running now
EDIT: I didnt get any errors
If the SDcard is fine. Then I'd reflash CWM Recovery.
I have. The only reason I flashed .2.8 was because of this problem. I have to send my phone to HTC on monday for repair so when I get I back (20 days later) Il start again from fresh. For now I'm gonna unroot and s-on etc etc... I hate sense.
Thanks a million for your help though!
Question: If HTC swap my phone with another, will my backup still work with the new one?
Off topic, I point blank refused to wait 21 days + for a repair. After some wrangling got an exchange. Sadly the exchange handset had severe case misalignment issues. Refused that also.
Yes your backup will still work. It doesn't matter what handset you use. The backup isn't tied to it.
Haha the speaker for calls doesn't work anymore so i hav to send it back. 20 days is gnna seem like forever lol. I'm gnna hav to look for my Nokia 3310. It's like 10 years old and its never failed me once.
As for my back up, when I do get my phone back i need to go through my apps and delete what I don't want.....or I could buy a bigger mem card and setup A2SD. Is there no way to browse inside the data.img file from the backup?

[Q] How to achieve the most complete backup solution? (I have root)

Hi
So I don't really mind if I have to hook it up to the computer or anything, I just want a really complete backup solution. It should backup pretty much everything I have on my SD Card.
I already have Titanium Backup Pro and upuntil now I thought it was complete, but after completely wiping my SD Card in an attempt to install the latest RUU (which didn't work btw, but that's off topic...) and copying my Titanium Backup-stuff from a computer backup I realized it's really really incomplete. To be honest I'm not at all sure what it even is backing up... maybe my Titanium is just set wrong?
So what happened is this... like I said my SD Card was wiped but I had previously backed up Titanium to my Dropbox and pushed the whole folder to my phone after the wipe. However none of my settings for Nova Launcher were saved. My Nova settings back up was not saved. Passwords for Google, Facebook, Dropbox etc were not saved. Data from Swiftkey was not saved. Kakao Talk and SMS messaging history was not saved.
Like I said, I'm not sure what actually was saved...
I don't really mind, maybe even prefer, if I could use my computer to store these backups instead of the SD since I don't always have a lot of space left on my device.
(I think I got the filesystem thing and updating to the latest RUU didn't work - that's what landed me in this situation to begin with by the way.)

Even if you pushed the whole folder back to your phone...did you actually restore the app/data using Titanium afterwards? Pushing the back-up folder back to your phone just means Titanium can access it. It doesn't restore everything unless you actually do so using Titanium.
Otherwise, making a nandroid backup using CWM recovery takes a perfect snapshot of your phone at that moment. So your texts will all be in place, passwords, settings etc. will all be as they are now. Of course, you can't really flash your nandroid over a new ROM just to restore app data, but it allows you to revert your phone back to its original state before flashing (like in your above scenario where you had a failed RUU installation)

Hi, thanks for your reply.
Yes I did restore. When I backup I do the full backup thingie in batch operations and when I restore I do the restore apps and system data + restore app data.
Yeah, I was thinking of Nandroid too but doesn't that just do non-SD card? I'm very new to Android but isn't most of the stuff I actually care about (app data and such) on the SD?
titanium doesn't restore system bits by default and google/facebook/dropbox is integrated into the OS.
You CAN force it to I believe but it WILL break things if you change your ROM at all.
IN my mind a small issue doesn't take long to sign back into those services as long as all your apps and data is intact thats all good.
If you have the filesystem thing I STRONGLY SUGGEST you up to 1.29.xyz.11 before you do any more custom rom/CWM work. Even relock/RUU, OTA then unlock and go. I had very bad experiences with this bug.

Hi. Thanks for your reply.
I totally would upgrade to the RUU if HTC there wasn't this small issue of the RUU not working. I live and bought my phone in Sweden and my CID confirms it's a european phone - however when I run the RUU it formats the phone and transfers about half the ROM then setup says "nope, wrong ROM." and leaves me with a dysfunctional OS. I'm also on a Mac so I have to run Windows 7 in VM Ware Fusion and starting that stupid RUU-file and everything takes AGES. I've already spent the better part of a day and night trying to get it to work and if I'm opening that RUU one more time with VM Ware if it doesn't work I think I'm gonna hang myself. So very very very sick and tired of that bullcrap. So... for now I'm either waiting for access to a Windows computer so I can try all of the RUUs and see if my phone's transmutated into the wrong region OR I'm awaiting an S-OFF mod so I don't need to use RUU.
As for the logins and such, it's not only google/facebook/dropbox. It's also Twitter, Evernote, Swiftkey and well... pretty much everything. Chrome seems to be logged in. AnkiDroid didn't get to save it's data (which luckily is saved in the cloud... and backed up manually).
Google Music offline data would be nice to keep to since it's pretty slow to sync. Plus I have to look-up what I actually want everytime I reflash.
Also, if I'm only flashing an upgrade to my current ROM must I really enter all the passwords again anyway?

Not sure if its not vmware thats breaking your RUU..... you can check your CID in fastboot and verify, if its supposed to work then its supposed to work, its vmware breaking it.
Hey at least you can flash a ROM right? 10 minutes entering passwords again is a lot less problems than a lot of people have encountered (including me, I got a corrupted super laggy file system IO after CWM and the disappearing SD card space bug hit at once).
As for nandroid, yes it doesn't touch your sd card but otherwise its 1:1 I've always gotten back from a nandroid with everything exactly as it was

Maybe. But it's very strange that VM Ware would be breaking a RUU isn't it?
Either way it means I need access to a Windows computer, either because VM Ware is breaking or because it's too darn slow. Indeed I have checked my CID in fastboot and it does say euro (well, I don't remember the CID itself but it correlated to euro).
Thanks for all your help. Greatly appreciated.
no probs good luck
edit: are you sure you are unbranded. If you are branded (Carrier handset) you need the carrier's RUU
its not that strange vmware breaks it, you are doing something that requires low level write access via USB.

root, flash, backup file moving help

Hey quick question,
so I make a backup of my system for flashing. Then I move the backup onto a folder to my computer same with my titanium backup folder. So when I wipe and flash a new rom, I have all of my files for my system backup and my titanium backup on my phone. After I restore all of my apps after flashing the new rom, can I move the backup files and leave them on the computer as well as the system backup to save space? Is there anyway that I can still restore the system if it gets stuck in a bootloop - (besides flashing a new stock one)?
basically I want to store the system backup and the titanium backup on my computer so they are safe and because they take up about 4 gb of space on my phone.
I tried to be clear but let me know if I should further explain
Thanks
I wouldn't backup system apps with titanium, because they can vary from rom to rom. As long as you properly wipe your phone before flashing, you shouldn't get bootloops(can still happen). If you get a bootloop, try pulling the battery 1st. If your phone still bootloops, you have to use download mode and ODIN to flash stock ROM.

right which I have done before. I just want to know that if my phone does get stuck somewhere (has happened before, and I had to flash a stock rom and lost everything - lost backup) Would I be able to move my system restore and titanium backup files from my computer to my phone to be able to recover?
Basically store backups on computer, then if something happens, be able to transfer them back to phone
Thanks for the help
Generally it's good to leave backups someplace where they won't get easily corrupted or lost. Since the S3 has a microsd slot, sure, keep them on your computer and move them over if necessary.
My SOP is to keep the current backup on the microsd, and store the backups on my computer. Then if I need to reflash/nandroid back, they're there, and if my microsd is corrupted I have a known good backup.

As long as you can get into your custom recovery after anything happens, backups will work. Make sure to backup system, data, and boot. If not and you have to flash using ODIN, like starting from scratch, you may have issues such as md5 mismatches.

ok I was just looking to see if it was possible or not to transfer backups from computer to phone if the phone cant turn on ie. stuck in download mode or recovery mode.

[Q] help recovering with TWRP after failed ROM flash

I've found myself stuck trying to flash a ROM. I'm a newbie, this was my first attempt at something like this, I though I read enough about the process but I guess I screwed up something. I will try to be to the point.
Phone: Samsung Galaxy S3 AT&T i747
Rooted phone with Casual, installed ROM Toolbox and purchased the pro upgrade.
installed TWRP 2.5 and made a nandroid backup, the only place this backup existed was in internal storage.
used ROM toolbox to backup user apps and user data
selected cyanogenmod 10.1 RC5 from within ROM Toolbox and there was a requester for gapps and a checked the box for that also. When the DL was complete I installed the ROM queue with those two items and I checked the boxes Wipe Data & Cache and Wipe dalvic-cache.
Phone went to recovery mode (i guess) and appeared to clear the memory and load the new rom, the phone rebooted and I got the cyanogenmod boot screen but then it went to a requester saying:
Unfortunately , the process com.google.process.gapps has stopped.
When you hit ok you get:
Unfortunately, setup wizard has stopped.
this requester never goes away, just keeps popping up when you hit ok.
So I removed the battery and booted the phone in recovery mode and try to restore but the restore nandroid file in not shown. If I hit the center button in the restore window it says "updating partition details" but never returns.
Whenever you power it up normally now you end up in this gapps loop.
My searching suggested I may have tried to install the wrong version of google apps somehow. What are my options for trying to recover from this? Does my backup still exist somewhere?
If process.gapps is your only warning you can try to reflash the gapps zip from here. http://goo.im/gapps/gapps-jb-20130301-signed.zip If this does not fix your problem, you will have to head deeper into the rabbit hold
You can look for your back with a file explorer. Should be in sdcard/TWRP/BACKUPS/******** (random number). If you dont see them here, check your ext-sd in the same location. If you don't see them, they are gone. Do a Nandroid backup now just to be sure you have one. You should chose to back it up to external in TWRP. As for your FC problem, it would appear that you have not wiped fully. You will likely need to factory reset. the problem is this will remove everything. Titanium back up is a great product for situations like this. If you have used it, you can transfer your backup from the internal storage while connected to your pc. Also copy your DCIM folder as it will contain your photos. This is why you will need to do another Nandroid, because worst case scenario, you can just restore this one.
Thanks for the reply. I will try to reflash the gapps file from the external as soon I can download it, the site is having some trouble right now. I made another Nandroid of the phones current state and stored it to external. I did also have Titanium backup and had backups of the whole system with it. Unfortunately they are also only on the internal storage.
Re-installing the gapps zip file off the extSD from within TWRP did the trick. All the data and backups I created are also still there and are now backed up in several places.
Something that compounded the problem was the 64GB sd card I have for the phone. I was not able to mount it on either of my linux mint machines or an XP machine. Some oddness with the exFAT file system on it, I used a 4GB card I had laying around and it worked fine.
Thank you for the help, the phone is now running CM which is what I wanted and I learned a few things too.

I just bought a 64GB card as well. You may be having troubles mounting it due to a partition that comes factory in the SD. If this is the case, you can look at post #57 on the following page http://forum.xda-developers.com/showthread.php?t=1915385&page=6
It helped me tremendously.

SD Card File System Problems Flashing ROMs

I have flashed a CM11 unsuccesfully and today sucessfully flashed AOSP Kitkat. I have found the file system is screwing with my sdcard. I have emulated/o, emulated/legacy, SD0, and SD1. I always run a Nandroid before flashing and that completely disappeared from my internal storage, it was not in any of the directories.
Not only that but after I booted up only a few of my apps were restored by Google restore. I installed Titanium and it had nothing. It informed me that the phone ID had changed and asked me if I wanted to change back for compatibility. I let it do it and ended up with a Titanium backup from a couple phones ago.
What the hell is going on and what is the best way to deal with the storage file system after a flash when one has these extra directories? Can I merge? I'm afraid to delete one because I do not know that it will not have some data I might need.
Thanks
