Re: [RECOVERY][X920d][X920e]ClockworkMod Recovery v6.0.2.7 Touch [2/6/13]

Hi,

Im using X920D

A. Recovery Version : ClockworkMod Recovery v6.0.2.7 Touch X920d

1. Fix permission - not working.

2. Mounts and Storage:

- unmount /cache = unmount/mount OK

- mount /data = mount OK , unmount FAIL

- mount /sdcard = unmount/mount FAIL

- mount /external_sd = unmount/mount OK

Recovery logs : http://pastebin.com/raw.php?i=4wvjVsh7

B. Recovery Version : ClockworkMod Recovery v6.0.2.8 Touch X920d

1. Fix permission - not working.

2. Mounts and Storage:

- unmount /cache = unmount/mount OK

- mount /data = mount OK, unmount FAIL

- mount /sdcard = unmount/mount FAIL

- mount system = unmount/mount OK

- mount /external_sd = unmount/mount OK

Thank you, CWM recovery r0x!
[HTC Butterfly] Flyhalf205:
Wow. Thanks for response. No one would never respond int the DNA section. Will fix this. Probably just needs a new recovery kernel.

EDIT: I had one guy that had a X920D and we was able to mount everything.

Hi

When I try and flash the recovery I get the following error

sending 'recovery' (7006 KB)...

OKAY [ 0.987s]

writing 'recovery'...

FAILED (remote: image error! (BootMagic check fail))

finished. total time: 1.021s

using D model Butterfly and currently have the 6.0.2.7 version installed (touch) and working

I run the erase cache command first and then the flash recovery, I have tried the original zip file name and also renaming to a short cwm.zip and both result in the same error message.

I hard restarted both via volume and power buttons and also via ADB, both ive the same message
[HTC Butterfly] red_trela:
I flashed the classic (i.e. non-touch) recovery on my x920e and switched directly into recovery. There, I get the usual menu plus a few messages at the bottom:

CWM-Based Recovery (by Fluhalf205) v6.0.2.8

E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

And, if I try to backup the ROM it says:

Can't mount backup path.

Mounting anything fails, too and so does formatting /cache (make_ext4fs failed on /dev/block/mmcblk0p33).

Not much working yet, but thanks for the effort!
[HTC Butterfly] jlevy73:
Same errors for me on my x920e. Thanks for your time in doing this for us.
[HTC Butterfly] toolhas4degrees:
I have this error and im on 6.0.2.7 touch otg but it happens after a fastboot erase cache in cmd, don't think it's just 6.0.2.8 recovery
[HTC Butterfly] Onepagebook:
you da man bro;)
[HTC Butterfly] PG101:
Same errors here... and I cant mount /sdcard to push files into the sd card (storage) while in recovery.. I know I can use ADB.. but this is an easier method ;)

Edit: And seems stuck on fixing permissions :(
[HTC Butterfly] Flyhalf205:
Re: [RECOVERY][X920d][X920e]ClockworkMod Recovery v6.0.2.8 Touch [2/15/13]

You won't be able to mount the sdcard because of the location of the physical mount is in data/media. ADB is the only way to move files. And It's reason why data can't be unmounted.

But will the recovery allow you to make backups or restores?

For those having problems. Try using if Rom manager will let you or o know with my phone. If I turn it off and boot into bootloader first. Everything works.

[HTC Butterfly] soyuutaku:
I flash this touch recovery to my x920e, but it won't start adb in recovery...

any idea how to enable adb?
[HTC Butterfly] Flyhalf205:
On my DNA. To get ADB running. I have to turn phone off. Make sure fastboot is disabled in power options inside ROM. After phone is off. Boot into HBOOT then recovery. ADB usually runs then.
[HTC Butterfly] Flyhalf205:
I've attempted to fix the ADB issue. Can I get someone to test it for me?

This is not an updated touch version. Touch version will be released after I find out ADB works.

Thanks guys!
[HTC Butterfly] Flyhalf205:
Updated again! Still v6.0.2.8. But now can be flashed officially in Rom Manager. Use Rom Manager to backup and restore roms or install zip files for best results.

Also Added DLXJ recovery. Not sure if it will work with you guys or not. But also can be flashed in Rom Manager. :)

Please Post here in this thread if you have any problems and mention the device model you have

Re: [RECOVERY][3/7/13ClockworkMod Recovery v6.0.2.8 Touch][X920d][X920e][DLXJ]

Sorry..for asking but why I can mount my internal sd card thx for help:(
[HTC Butterfly] Flyhalf205:
The reason being is because it is located inside your data partition. It is a big explanation. If you would like to read this you can to get a better understanding. http://teamw.in/DataMedia
[HTC Butterfly] fastcx:
Re: [RECOVERY][3/7/13ClockworkMod Recovery v6.0.2.8 Touch][X920d][X920e][DLXJ]

Latest touch for x920d has unable to mount cache partition error on menu, it includes log file, command file. I'm currently back to previous version cause current version unable to flash zip files successfully.
[HTC Butterfly] lombers:
Same problem for me with this version too. As a result I also can't use it to make backups...
[HTC Butterfly] Kroutnuk:
Could you check that problem Flyhalf205 ?
[HTC Butterfly] Flyhalf205:
I can maybe get a test build out. But nothing has changed in in the builds. Just a newer built.

If anyone can get me confirmation and what partition cache is really on. ADB into your phone and do the following command... cat /proc/emmc and get me the line where it has cache on it.

Can also be done with Root Explorer just navigate to file and open up with text viewer. Just give me the line cache.

Won't be until later for me till I can get it out.

Does the classic version have cache problem?
[HTC Butterfly] Kroutnuk:
I have :

mmcblk0p33: 17fffe00 00000200 "cache"

I didn't try the classic version
[HTC Butterfly] Flyhalf205:
Re: [RECOVERY][3/7/13ClockworkMod Recovery v6.0.2.8 Touch][X920d][X920e][DLXJ]

Its set up correctly. No idea why it can't read mount cache. The phone itself has problems mounting system every now and then..

What happens when you wipe cache then try to mount cache.
[HTC Butterfly] soyuutaku:
Adb still not starting in Recovery. Download via ROM Manager.
[HTC Butterfly] Flyhalf205:
Honestly I don't know why ADB won't start. Starts on every other recovery but the DNA X920d and X920e. Sometimes it will work when entered with "adb reboot recovery"
[HTC Butterfly] Flyhalf205:
And it looks like I had the mount /cache problem like you guys. I just formatted /cache inside of CWM and it started mounting again.
[HTC Butterfly] QWERTY0722:
hello I wanna know if I already flashed the CWM touch recovery, I can't apply the OTA update.

so I want to flash back to the stock recovery, can you help me ?

my device is HTC J Butterfly (DLXJ)

thanks
[HTC Butterfly] Flyhalf205:
Re: [RECOVERY][3/7/13]ClockworkMod Recovery v6.0.2.8 Touch][X920d][X920e][DLXJ]

I should have the stock recovery at http://goo.im/devs/Flyhalf205/DNA just flash it and then apply update.
[HTC Butterfly] Bus Driver:
Hi,

I'm rooted with TWRP. So if I install the CWM recovery,this will override the TWRP? And do I flash the stock recovery with CWM? Will this unroot the phone? I just want to get the OTA updates and then revert to CWM.Thanks..I'm new to HTC..coming from Samsung.
[HTC Butterfly] Flyhalf205:
Re: [RECOVERY][3/7/13]ClockworkMod Recovery v6.0.2.8 Touch][X920d][X920e][DLXJ]

Usually ota updates doesn't do well on custom roms. Flashing this will override twrp. If you want to flash ota you must install stock recovery then install ota then flash cwm. If root is lost. You can always install root in recovery.
[HTC Butterfly] Bus Driver:
Thanks for the prompt reply..I am on stock Rom,only just rooted. Just flashed CWM through Rom manager but notice it's unable to mount the external SD..guess that's what the previous posts were all about.

So coming back to flashing the stock recovery, this can be done using CWM and flashing the stock recovery Img from the link provided earlier or do I still need to use a pc and adb?
[HTC Butterfly] Flyhalf205:
Depending on which device. The external_sd is either the actual sdcard or the OTG USB drive. But ues PC and flash with fastboot.
[HTC Butterfly] lombers:
Tried this and still doesn't work. I get the following:

E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p33
Error formatting cache!
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log

Even tried using the "Wipe cache partition" and this didn't fix it either... :(
[HTC Butterfly] Flyhalf205:
I'm not really sure..I am getting the same thing and can't get it to go away.

I have three new test builds if anyone could test. I do believe I have finally fixed adb.

Thanks!
[HTC Butterfly] lombers:
Hi FlyHalf just tested the build above and I have the same issues as my previous post. Tried formatting cache but still get the permission denied error.

The last known working build I have from you is CWM_Touch_v6.0.2.8_DLXUb1_X920d which has a date of 15/2/2013. I can format the cache correctly in this build and that works, which means I can backup and restore my ROMs.

Not sure if this helps, please let me know if you want any other info.
[HTC Butterfly] Flyhalf205:
Thanks for the feedback! I do not know why it won't mount with the newer 6.0.3.0 version. I am also getting the same problem on my DNA but not my Rezound.
[HTC Butterfly] Flyhalf205:
Have a newer version up in the OP. Not sure if /cache is working. It started mounting for me. But ADB should be working.

You can download the new version with ROM Manager if already rooted.
[HTC Butterfly] ccombe:
I still can't get Dalvik Cache Wipe to work on CWM... keep pressing the option and it reload these menu as if nothing happened.

also what are the implications of the cwm being built with the 10.1 source, does that make us any closer to having cm 10.1 on butterfly?
[HTC Butterfly] Flyhalf205:
Re: [RECOVERY][3/28/13]ClockworkMod Recovery v6.0.3.0 Touch][X920d][X920e][DLXJ]

I don't know about the dalvik wipe.

But once we get the DNA up and running with cm10.1 it will be very easy to get you guys running it.
[HTC Butterfly] lombers:
Hi FlyHalf, same issue for me with /cache, tried formatting etc but I keep running into the same issues as I've posted before.

Thanks for your hard work on this, sorry for being a PITA.
[HTC Butterfly] Flyhalf205:
I'm sorry but there is nothing I can do to fix /cache :(
[HTC Butterfly] lombers:
Do you know what the issue is? Is there anything else I can do to help with this?

It's weird because when I go back to the older build that worked for me, I see the same cache errors when recovery runs for the first time. However if I format cache on that build it just works, no errors at all.
[HTC Butterfly] Flyhalf205:
It's a weird thing. Not sure what causes it. My DNA I got /cache problems on my test build of 6.0.3.0 but the version from last night has no /cache problems. I don't know what causes it.

Trying to set up ClockworkMod Recovery through the ROM Manager fails. I can choose the device (which shows as "HTC Butterfly (dlxu)" and is a x920e) but when I choose "Flash (...)" it simple says "An error occured while downloading your recovery". Tried a couple of times over a couple of weeks. The devices connectivity is fine otherwise, so it must be a issue with ROM Manager.
[HTC Butterfly] Flyhalf205:
Version 6.0.3.1 is out. The big diff is you now can back out of adb sideload
[HTC Butterfly] red_trela:
Well, still the same with 6.0.3.1 ;( Also, when I try to install recovery from ROM Manager (instead of fastboot), it still says it can't download the img. :(

The same here with x920d Europe version ( no micros-card) v6.0.3.1 doesn’t work but the old one v6.0.2.8 works
[HTC Butterfly] Flyhalf205:

[HTC Butterfly] GoLfWRC:
Not yet. Will try it now. Thanks for a suggestion.
[HTC Butterfly] Flyhalf205:
Later today I'll update to 6.0.3.2 recovery. But best thing before flashing a new recovery on the newer HTC phones is to fastboot erase cache then fastboot flash recovery.

My phone prompted me today that an update to 4.2.2 was available.

Its a takju Nexus running with an unlocked bootloader and rooted but otherwise stock rom.

I've tried to get it to do the update, however it reboots to a screen saying "applying system update" then after a few seconds flicks to a screen with an android with an exclamation mark, and the word Error below.

Is this because i'm rooted? or is there something else going on?

Thanks

Kevin
[Samsung Galaxy Nexus] reysonance:
Extra root files shouldn't cancel out the OTA, however, overwriting system files, or modifying system files will. For example installing busybox on system/bin, modifying etc/host etc. Installing mods and replacing apps on /system may also be the culprit.

Just flash the system.img over your current system, also make sure you're running the corresponding recovery, radio, kernel, and bootloader that came with your takju factory image. Do that and and try the OTA again, should work. If the OTA doesn't show up this time, you can download it from the OTA links thread and sideload it via ADB.

Alternatively you can install a custom recovery directly from your phone, back up all of your apps with TB, and flash Bigxie's 'stock' 4.2.2 if you don't have access, or don't want to mess around with a computer. Of course you won't get direct OTA updates from Google that way, but since he usually update his build pretty quick that shouldn't pose much problem.
[Samsung Galaxy Nexus] chelseaeuro:
I'm unable to update to 4.2.2 as it says "couldn't download". Not sure what's going on here.

P.S : I don't mean to hijack this thread.

Try clearing Google Services Framework's data+cache maybe? Or try in a couple hours, the problem could be in the server.

[Samsung Galaxy Nexus] Aragorn84:
Thanks

Just to confirm, if i flash the system.img over my current system, will that delete all my installed apps/data? Which system.img should i be flashing? the one from 4.2.1?

Is there a list somewhere of the version numbers for the various parts (recovery, radio, kernel and bootloader) so i can check they are correct?

Also, is there a way i can flash the OTA update with some error logging or debug output turned on, so i can see what its actually failing at?

Cheers
[Samsung Galaxy Nexus] reysonance:
Yes, the one from 4.2.1, check under Maps > Settings > About, it should gives you the version you're currently running, download it from the factory images page if you haven't already, and no, it should not wipe any apps+data, but back it up anyway if you're worried, better safe than sorry, I'm generally paranoid about data so I always backup, but no it shouldn't wipe anything. You'll lose root and that's it.

And for the bootloader and all that, it all should come all packaged on the factory image, so if you flash 4.2.1 via toolkit, or manually and haven't installed any radio or kernel you should be safe. IIRC, the bootloader version is PRIMELC03, the radio is XXLH1.
