Cant mount cache recovery log
I had a normal factory setup Samsung Galaxy Y GT S5360 and I tried to install a new KItKit Rom but Its all gone pearshaped !!
I have tried a load of different images which all load ok with the exception tat i get error messages like Cant mount cache recovery log.
I have also tried using odin to flash it back to its origonal firmware but after selecting the 3 files it runs and finishes saying failed 1
The phone does go into recovery mode and then I can run any of the cwm's that i have tried.
Doesnt exactly go into download mode as per any pictures ive seen ! I can either put it into recovery mode or with another key press put it where just the battery icom shows up when connected to the pc.
I have the samsung drivers installed ok on my pc.
Should I just give up ! On one image I did manage to boot it but it kept restarting unless the sim was out but i have not recreated that again!

you need to reboot to recovery again after restoring cache to see if it worked
you can do it using biels kernel - works fine on that - you will have to convert your system to ext first
first flash biels temp cmw

mount everything and flash the ext converter tool (unmount and remount system)

once you have booted cm7 you can go back into cwm make a nandroid backup and then restore cache
if you want to convert back to rfs to use stock based roms you will have to flash stock rom via odin
note you cant boot stock roms using this kernel but you can boot cm7 roms if you want to flash cm7 after doing that

if cache is not mountable after the rom has booted and you get error 492 with trying to download apps just make a nandroid backup and then advanced restore cache from that nandroid backup
oh and as you are using cm7 you need to flash gapps to get playstore and so on
you can download it from
http://goo.im/gapps/gapps-gb-20110828-signed.zip
make sure you unmount then remount system and data before flashing

I understand, thanks !
So when I started out with this I wanted something like KitKat as I iunderstand you can better control app access to mobile data and wifi with various apps that are available. All the apps for this 2.3 version of android did not actually work !
So do you think I could now upgrade to a newer android or should just leave it ?

no as there is no kitkat for galaxy y
there is also no jellybean
there is ics via cm9 but there is no audio/mic so its not useable as a phone
cm7 is the best you are going to get with nearly all core functions working (the only thing that doesnt work is streaming audio via bluetooth and fm radio)

its a bit strange to me that your stuck in recovery, usually if you flash recovery and it formats system (happens some times) if you make a clean install the rom should boot.
Last thing you can try is to format every thing in this order.
Go to mounts and storage.
Mount/system
Mount/data
Mount/catch
Format/system
Format/data
Format/catch
Go to advanced and whipe delvic catch
Then just follow the rest of instructions that @Paget96 said.
But yes if that doesnt work flash via kdz

Well If you want to flash a custom rom again, then flash another custom rom aside from the one that caused such strange thing. Follow Paget96 flashing steps, see if the problem persists, and make sure it's for L7 p700. If you haven't tried cyanhacker v2.0 then try it.

Mi Note 2 bricked! Request for solution

Dear all,
I stupidly bricked my Mi Note 2 by doing OTA with TWRP installed (at least I think that is the reason) - although I have done this once with success, but at the second time, the phone won't boot anymore.
- In TWRP, it says that the internal storage is encrypted and prompts me for code
- In TWRP the storage cannot be mounted (none of the partitions can be mounted)
- Tried to flash stock ROM or stock recovery in fastboot mode, seems like the internal storage cannot be accessed either
- With Mi Assistant, still no lock
It seems that the internal storage is totally corrupted...
What can I do without going to service (luckily I'm in China right now...)? Perhaps ADB sideload stock ROM would work?
Thanks!

Delete data partition an try reboot

Can't. Got some error message - see attached.
Sense like that the internal storage can't be found at all...

Also tried to side load DEV rom via adb, but got the attached error.
No clue how to proceed...

1. Format your data partition, and then reboot TWRP. This will decrypt your phone.
2.After entering TWRP, wipe all partition and then reboot TWRP
3.Copy your ROM file into your phone, and then flash ROM

Hi, I have assumed this as well, however didn't figure out a way to format the data partition. In my previous screenshot I showed the error ("unable to mount" or "no such device") when trying to delete the data partition.
Do you have a more detailed instruction?
Thanks!

Here you are.
See that "Format Data" ?

Do you want to switch mostly updated one and try again?

Actually I cannot flash any recovery now: FAILED (remote: flash write failure)

Download fastboot rom and flash it with miflash tool.

Can you enter fastboot mode ? If yes, then you can do (1)as dtsun said that; (2)flash the new version of TWRP(fastboot flash recovery xxxx.img ===> "XXXX.img" means the whole file name of TWRP image file), rebooting to TWRP again and then flash your recovery ROM.

Sorry for that. It's indeed that you have bricked your phone

Do this.

What error are you getting when trying to flash MIUI fastboot rom?
I have had this problem before on my redmi note 3, although the cause was from flashing TWRP not OTA.
I tried everything I could think of to try fix it, in the end flashing fastboot rom and clean all and lock with mi flash tool was the only way.
You'll need to use mi unlock to unlock the phone again but that is easy if you have done it before.
Did you use official way to unlock bootloader?

Reply to all above:
I unlocked the phone in the official way;
Miflash didn't work, because the internal storage is not accessible.
So lessons learned: never do OTA update if you have a custom recovery installed.
But:

From Custom to Stock - Bunch of errors

If you guys help me to go back successfully to stock, I'll make a guide to explain the process, maybe for all 3 models. I just need help on this one
I have an A2017G
So this is my fourth time trying to get back to stock. the first one resulted on a DFU brick. The second one was through MiFlash and the system had random reboots. The third, I flashed tron1's A2017G B04 Bootstack and a DrakenFX flashable zip (for the U, just wanted to try) and TWRP said that there was no system which turned out to be true... i had wiped system, data and caches before, but it seemingly installed okay...
I also tried to use MiFlash again and get B10, but it started to throw an error out of the blue (the specified cast is not valid, or something along the lines). I used it at least 4 times before.
So what zip should I use? I never tried flashing one of those update zips (I have full official B10 on the sdcard) but I believe they won't work. Please tell me if they do work...
again, if i manage to get SAFELY to stock and AVOID DFU I'll make a nice guide so that we stop asking. Most custom roms are flawed, for ex. Lineage has bad compatibility, Pure Nexus (the one I'm using now) has extreme, Galaxy Y grade lag, and RR simply works worse than stock (it's probably the best one of the bunch though).

i am in in the process of going back to stock(A2017), will let you know.

I don't think you should when having TWRP loaded on your RAM and your system probably not there...
My DFU brick was just because of that
but if you insist, turn your phone off and hold the two volume keys, then connect the USB cable (it has to be connected to the PC obviously)

Still had TWRP

A2017U from LOS to stock using the files on https://forum.xda-developers.com/showpost.php?p=68873482
The only reason I mentioned it when I have the United States model is because I have ran into a problem on multiple devices going from CyanogenMod to any sort of AOSP-based ROM without clicking that format data button. The first time I ran into the problem comma I could not mount my data partition.
I advised @satish.yarramsetti about this here. @satish.yarramsetti, can you confirm that the ZIP I linked you to in the other thread is the one you flashed and is booting?

I am Nuclear Rom(LOS Based) and tried to go back to stock. I have followed all tutorials but when i try to reboot, TWRP warned me that there is no OS. So i didn't reboot as it might remove TWRP ( it might have booted but not sure) ( i also flashed NO verify zip) , so i thought of formatting in wipe menu which caused a lot of problems like cant mount data & device busy errors . I tried to flash N boot loader and mod but every FLASH is getting failed. So i decided to restart and luckily i have TWRP and no os and my nandroid back up niether worked.
Finally i flashed Clean LOS.

Understood. I have received that same warning in the past after flashing stock. At any rate, if there's no OS installed, there's nothing to overwrite TWRP. The phone would just sit at the ZTE logo and you would have to hold Vol Up+Power to get back into TWRP. If you decided to try again, at least you know you can restore LOS if it doesn't work... Good luck.

It's not workin. I've tried it serveral times, changing the /systems to F2FS and change it back to EXT4.
/systems, /cache and /data belong to EXT4 right ?

That's really expensive. If that's the only way, I'd rather buy a new phone.

Can you give me a detailed answer? I don't know where's the partition.img

Just google search Kraft-A6000_S061_160727_WCB0C57CA0 and download the zip firmware file, place it on the SD card, boot into twrp, wipe system, data, cache and dalvik cache. Flash the zip. See if this works.

Bro it will not work because you can't mount system or data
If system is not mounting then you can't flash ROM !!

You're right, I can't flash anything
I haven't tried QFIL (Well, I've tried it but QFIL not detecting my phone)

How are you connecting your phone ??
Is there any file name partition.img in your firmware folder
Check i f qualcomm drivers are installed !!

It seems there have been no improvements, therefore I think this widespread problem shall be the death of many of our devices.

This happened to me once. Since the error was failed to mount partition, I went to mount (in TWRP) and selected all the partitions available there and that solved the issue.
