Hi guys, hoping you can help me out. Noob, yup.
Nexus 7 2012 Wifi.
My Nexus was getting slow, so I successfully converted my system, data, and cache to F2FS with SlimKat.
In the process of this, I converted my Cache, System, and Data to F2FS.
The SlimKat F2FS rom was working fine. All was well.
Here's where I made a series of errors...
I decided to restore the Nexus back to factory settings/stock 4.4.4. I had some problems with my nandroid files, so I decided just to convert things back manually in TWRP. My thought process was to: A. convert Data and Cache back to ext4, B. Install factory rom from System, C. convert System back to ext4.
My thought process was apparently wrong.
Here's what I did:
1. I copied the 4.4.4 Factory Image (.tgz) to the sdcard (first mistake. I assumed the official download was a .zip but it was a .tgz).
2. In TWRP, i converted the Cache and System to ext4.
3. Tried to install stock 4.4.4 rom but couldn't install it because it was .tgz.
4. Not knowing what else to do, I converted the Data to ext4 as well. So in my eyes, everything was "put back" to ext4 like it was before. Since everything was "back to normal", I thought Nexus Root Toolkit could take me the rest of the way back to normal.
5. In Nexus Root Toolkit, I tried to "Flash Stock + Unroot", but it gave me errors (picture is attached)
6. Now I'm in bootloader. Trapped. I can't even get back into TWRP anymore (and I don't understand why).
Sorry for the noob trouble. Hopefully there is still hope for my Nexus.
Thanks in advance for any help.
In fastboot mode (i.e. Bootloader), use fastboot to flash the latest TWRP or a factory image

Instead of doing these whole procedure via .bat file plss try it manually yourself and install latest twrp and then format your system and other partitions with desired format and then flash manually system.img and other stuff manaually
Solved!
Hey guys, thanks for the help.
Here's what got me through it:
1. Learn how to fastboot, adb, etc. WITHOUT Nexus Root Toolkit so you understand what's going on.
2. Don't assume that any USB port or laptop will give you the same results. My attempts to flash the system with a custom rom failed time and time again. On the advice of other threads, I tried the same thing again via a different USB port, and voila it worked! Perhaps it was not a 2.0 port.
In summary, I needed to fastboot erase, then fastboot flash the partitions. And most of all, I had to try it on a different USB port if it failed unexpectedly.
Hope this helps somebody else!
Update: i Fixed it by myself. Thanks
Hello! i am new here. i have samsung galaxy s3 neo i9300i. updated to android 4.4 with TWRP installed. i wanted to flash cm 12.1 rom by "Rox". but he wrote in order to flash one need to change the partition from ext4 to f2fs which i followed but didn't find in TWRP wipe>advanced>change partition there are others but not f2fs. because of this problem i have flashed the ROM & GApps & they both flashed successfully but when i rebooted the system, download mode appears. did rebooted several times but the problem was still there. plz help me. i want CM 12.1. THANKS
WTF.... Well, guy, you needn't to convert partitions, you only have to wipe data, dalvik and cache and flash ROM & Gapps.
If you want to convert, convert only data and cache... idk why you haven't this options... Well, I never converted this files, and CM12.1 is working fine.
not working

i tried but when i flashed, its stuck in the download mode. just like Rox wrote i did that. nothing more.
Did it by myself...
The problem with my phone was the TWRP 2.7.1.0, + due to root ota updates not worked, so i downloaded another rom 4.3, flashed it, updated to kitkat (ota), flashed TWRP 2.8.5, flashed the rom (cm 12.1 by rox), flashed the gApps... now it's working... Thanks...
I was trying to convert my system, data and cache to F2FS but after the conversion I can't use Data anymore (apparently it cannot mount data and system anymore).
Could be a problem LinkedIn to the grarak modded 3.0.2 I'm using for Exodus 6?
Any feedback is welcome!
Up
Most probably as the official one from twrp supports f2fs natively.
I would recommend to go back to official twrp convert to f2fs properly from there and then flash the modified one, do this if you are brave enough, i havent tried this method but it should work. If all fails stay on ext4 till garak or twrp updates their twrp versions.
Thanks for you answer... I thought the same... I'll try as the new phone will come and let you know...

Hello,
i need help. I messed up my phone while trying to repair my only read mode system partition after boot.
Current state:
Phone CAN-L11 with EU Firmeware and working TWRP Recovery.
I did a full wipe, but have no data partition to restore, because this couldn´t be saved with twrp while i made my first nand backups during no read access to data partition.
My phone always shows 2 times the huawei logo and then boot in erecovery from huawei where i tried to restore, but it shows always "fail to get data" (wifi works).
When i restore all partitions backups that i own via twrp i miss the data partition (is the cause why it wont boot - isn´t it?)
Now i searched for any img that i can use to get my phone working again - anyone has a tip what img i could use (i have a huawei update extractor) - through twrp or fastboot.
Could anyone help me with a twrp backup or a img file of data partition - or has another tip how to get my phone working again?
Thanks for tips!

I think that you need a system.img, so you can flash. This system imagem would write everything you need, so you can boot normally.
Have you tried to dowload @bluesmoothie backup from dropbox from the Root and Recovery post?
Here is the link, in case you don't find it https://www.dropbox.com/sh/qrk0fbpn5rnukxn/AAAmhFwBTNoqq0sWfCH-VMHLa?dl=0

Here the full Backup for the CAN-L11:
https://drive.google.com/open?id=0B134drJ4-Ed0R3VSY3A5NGpjVWc
Format /data, reboot recovery and than restore from backup. After the restore is complete make a wipe.
I restored my system from twrp (original first save). But that did not help.
After that i loaded the can-L11c432 update.zip from huawei and extracted with others the system.img - that also did not help to boot.
Tomorrow i flashed the orignal recovery.img from c432 but i did not find an update.zip wich works to manually flash in stock recovery.
@Vinnom the link you shared leads to twrp.img (no system.img).
@-=MoRpH=- thanks, i will try and report back. Is this anyway a chinese version in there? I think i have the same struggle you had days back. Is your phone completely working again?
So sick that my phone did not work. Now working with my "old" LG G2...
I report back later - first family dinner

Inside the folder twrp and its subfolders there it is system.img. I'm downloading it myself.

@merlin21 yes it sounds like my problem after I tried to flash the emui5 beta.
My phone is fully working again with the backup I posted.
This is not the Chinese version, if nothing works, you can try the caz ROM. But there are massive problems with the gapps, they are not included in the rom.

i just flashed the twrp.img with fastboot from xelfmade v22.12. and then rebooted twrp.
Then formated data and confirmed with yes - rebooted recovery and tried to restore your twrp. It did not restore and aborted instantly with the error message
during restoreing cust...
extractTarFork() proecess ended with ERROR: 255
what could that be?
IT WORKS! Thanks @murph... I had to use the cust from my backup, but with your data partition it successfully booted again. Locking forward if i now have still the problem with read only system partition. I am away setting up phone again (and of course rooting, modifying etc.. but FIRST do a full backup after basic setup and safe in PC !!!)
Thanks!
P.S. how did you manage to back up data partition in recovery? I thought this wouldn't be possible?! What is the cost for having this full working twrp?
PPS. Somehow knock on screen for screenshot does not work - could be, that i have to log in with huawei id... does it work for you morp?

That only work if the is not rooted... Idk whats up with that, but for now i use the quicksetting screenshot function.
Somehow it worked with my rooted device before. Must be the decrypted data partition?
With the recovery of your backup I could not access data or change memory from data to sd. What version do you use?
I flashed xelfmades v22 and now have rw access and could backup all partitions and restore. Root and xposed modules everything works, just the knock on screen to capture don't...

May I ask how?
I'm kinda stuck personnaly. I have tried both Nand backups but no cigar. Still can't boot. I had the Data issue which I managed to get rid of.
I still end up with a ExtTarFork 255 kind of error. I tried to change the files attributes via adb shell, but it failed so I've got an OS-Less phone...
Any help would be greatly appreciated.

I copied the backup, which is linked somewhere in this thread, to my sdcard and restored it on my Nova using twrp. The extractfork issue showed up while restoring '/cust' so i disselected cust in the restoring menu. After that the restoring worked and my nova was able to boot.
Hope this is any help to you.

That didn't do the trick for a while, or I might have forgotten a step, but deselecting CUST did the trick.
Thanks for the tip!
Although, maybe flashing the Cust partition I found in one of the two upgrade zips via fastboot might have helped? I dunno...
But in short, for those who haven't followed through, here's what I did, but I'm not sure this is why it worked:
1. Bricked my device : be sad;
2. DLed all the posted Nandroid backup on this thread and others;
3. With fastboot, reflashed TWRP from Xelfmade using "fastboot flash recovery twrp.img";
4. Flashed the CUST.img I found in the UPDATE.APP of the update_data_full_CAN-L11_hw_eu.zip; or maybe the other, only one of the two seem to have it; I extracted it using Huawei Firmware Extractor; using "fastboot flash cust cust.img";
5. Created a "fake" backup to create the right folder structure on my SD (TWRP Couldn't see the backups) and put the Nandroid Backups I DLed earlier in it;
6. Reboot in TWRP and Restore all partitions except CUST;
7. Reboot, sweat, wait, cry, roll on the floor in fear, heard the huawei startup sound, cried as if it was my first born child;
8. Setup the fone and profit; then enjoy Nova goodness;
92.324. and probably most important, TWRP BAAAACKUUUUP!!!!!
All done!
Thanks for your help my phone is saved with your method!!!
i downgraded my MLA-L03 variant with this, but now im stuck in french language with no other languages to choose from

Frankly, I don't know. I had not modified the partitions prior to bricking my phone, so I think the partitioning was OK. However, I think one of the TWRP availble in this forum can format Data partition properly, which would utlimately allow you to select which File Format you want. I haven't tried it myself, and I haven't been able to do much with TWRP since I flashed Lineage unfortunately. Most of my Mods were just upgrading and I had to ADB Sideload pretty much everything since I flashed Lineage...
Sorry I couldn't be more helpful than that!
Hello,
I wanted to revive my old samsung galaxy J1 and try to install a ROM on it. I found a compatible cyanogenmod12 ROM for it.
At first i just wanted to get the phone back to boot up correctly but it was stuck on the Samsung loading screen. With no other option, i flashed TWRP recovery and found out the files were kinda corrupted. The log showed it was unable to mount data, cache and system. So i went online looking for fixes.
All said i had to repair them by going to "wipe" then "advanced wipe" and one by one re-formatting the files to FAT4 OR exFAT. and that's when i found out all the files were gone since none of the 6 options (EXT1, EXT2, EXT3, ntfs or FAT) worked.
I thougt installing the ROM would fix this by creating new files but since it was unable to mount system, cache or data., i couldn't do anything.
MY QUESTION: is it possible to recover anything or to manually create the folders and files since it's (unpossible) to install a ROM on it?
There's gotta be a way the files have been put on it for the first time....
