[Q] JB CM10 sudden bootloop. How to recover? - Defy Q&A, Help & Troubleshooting

Hi all, I changed the levels automatic brightness adjustments, then a call occurred and I aswered. When I closed the call, my defy+ rebooted immediately (no messages appeared) and then went in a bootloop: cyano glowing logo, then a single red LED flash, then it repeats.
Tried to clear dalvik cache, with no luck.
Is there a way to recover easily? Unfortunately I have no backups but want to keep contacts and application data. Not interested in keeping SMS's or photos.
Thank you

Contacts are usually stored with gmail account. I don't know about the app data though.

tried to wipe cache, dalvik cache, then install latest CM10 but ended up with the very same problem.
Should I only go RSD?

Make a backup of your /data in custom recovery, then wipe your /data partition (and cache/dalvik if you want), then reboot.
This will most likely get it to boot up again, then you can use Titanium Backup to restore your apps and app data. Do not restore your complete backup, because it most likely got corrupted, and do not restore System apps either.
You can restore SMS, by restoring Phone/Messaging Storage, and to restore Call Logs/Contacts, restore Contacts Storage. You might want to check the "Migrate System Data" checkbox in Preferences if it doesn't work at first.

Thank you, but I've already gone RSD. Good to know anyway. tnx

Sorry we couldn't find a solution in time.
For me, it's not that important; I full wipe at every sign of a bootloop. With the Desire I used to wipe all, including /system!
As long as you have a google account, you can reinstall the ROM and add your Google account at the beginning. That restores your previous setup of applications and appdata. Contacts are automatically synced and added to People.

[Q]Defy does not boot anymore(bootloop?)

Last night I upgraded from WIUI2.5.7(stable) to the new WIUI2.6.8(stable). It went well, <strike>I did make the mistake to wipe cache instead of dalvik cache after flashing</strike>, but I did wipe the dalvik cache after that. Then I booted into the defy, downloaded Titanium Backup from the market and restored system settings. Then Titanium Backup suggested I rebooted, which I did. After that I cannot enter the bootloader and it's stuck flashing coloured squares, I guess that is the ICS bootanimation.
My guess is my Defy seems bricked, but isn't. What do I need to do to rescue it?
Fixed it myself, I kept removing the battery and fiddling with the buttons and all of a sudden I was in the bootloader and reinstalled the ROM. What I need to know is what caused the problem. Probably certain system settings could not be exported, perhaps all of them? I understand that you cannot import from gingerbread to ICS, but I thought this kernal was gingerbread. And can I import contacts, whatsup settings, SMS etc?
NM, I cannot get get this rom to work when importing settings en data, I'll just go back to 2.5.27. Thank you all for your help, I appreciate it.

Have anyone try the CM7 120901 by tezet? I have encountered a problem in sending sms.

Yesterday, I have installed the new CM7 120901 by tezet. Almost everything is working perfectly. But when I try to send sms, it shows failure immediately, and the error code in sms detail information is 254. But it can receive sms normally.
I tried to change the SMS center in the menu after *#*#4636#*#*, but it doesn't work.
Is there anyone trying this rom? Do you have the same problem?
If you have the same problem, could you help to post this issue to the develop forum? I have the permission to post reply to the tezet's thread.
I don't have this problem....

It's a problem specific to Titanium backup on quite some roms for some time now (at least the CM9/10 in here) since it doesn't happens when you do the same with My Backup Root (another backup ap, free one, that works a bit differently than TB).
Try the rom without restoring apps with TB and reinstall them from market, only reinstall the app's data you REALLY need (like highscores, saved games, sms/call log and so on) and reinstall the apps manually (making an AppBrain list for that helps).
Restoring SMS and call logs via Titanium backup made my phone and sms apps crash, since then i'm using SMS Backup + (it's in the market) which backs them up on my gmail.
Restoring data for system applications usually makes them FC!
I've reflash and make full wipe, it's ok now. using go backup and all app don't have any FC

It seems to be solved by another wiping data and wiping cache.
It's strange that I have done the both wiping after installing the CM7 120901. Maybe the cause is that my phone is in fly mode when I installed the rom.
Thanks for your kindly reply.

No it's something that has to do with the flashing process, sometimes it seems unable to wipe properly the /system partition and some strange things happens.
It regularily happens to some people to have to make the whole process twice for it to work properly.
Now the technical explanation is surely out there, but it's out of my reach for now (and i'm not interested enough to search for it, since there is a workaround for it ).

[Q] Wipe Data/Factory Reset. What does it entail?

I am currently on CM10.1 and have been considering testing other ROMs for the Nexus 4. All ROM flash guidelines ask that I wipe everything and do a factory reset before I flash the ROM.
My question is does doing a data wipe permanently erase all data on the phone? Including installed apps, app data (game saves, whatapp chat logs, etc), SMS and Contact information, gallery files, wifi passwords, etc. Or is it just some ROM specific data. More importantly, if it is more than just ROM data, is this data gone forever or is it synced with the google cloud and is simply synced over the internet once the phone is setup with the correct google account again? If it is synced, what data is synced? I presume at least contact information is synced with the cloud but what about the rest.
I could find any clear information on what exactly wiping data entailed and what could be the expected unrecoverable losses possible. Also can I just take a backup of the data using some app (Titanium backup?)/nandroid backup and restore the data once the new ROM is installed?
Factory reset will, just as the name states, bring it back to the state is was when you first got it.
So yes, every app and data of it will be lost. This includes contacts, wifi passwords etc.
Your contacts, wifi passwords etc will be synced to the google servers, if you chose to do that when you set up your phone for the first time.
However, it will not wipe your sd card, so all your photos and music will be save.
I'd suggest you make a backup of your WhatsApp history, this way when you re-install it you will be prompted if you want to restore the messages from the backup.
Hope this helped!
EDIT: It is not suggested to restore data from a titanium backup, since this can generate problems.

Is there any difference between delete cache and data and doing a factory reset?
While doing a cache wipe, only files from the Cache partition are being deleted. These files were saved by your phone to use as cache. (Think of it as your browser history. if you wipe that, only certain files will be deleted, while the app itself won't be touched)
While doing a factory reset everything will be wiped, including the cache partition. Excluding the sdcard ofcourse.

Ooh, old subject haha.
The android OS IS your rom, so to have a full stock android rom, like you had when you first turned on your nexus 4, you need to flash the factory image provided by Google. Link to factory images
If you dont know how to flash these files, efrant has a great guide on how to do this. Link to the guide

By wiping rom, did you mean to wipe system off your device? If that is what you meant there, then your device won't boot after that because there is no OS installed. To clear your confusion factory reset only set your device back to the default settings when you buy it. Means it will wipe your downloaded apps, cache, saved data, contacts, messages etc.. Some stock recovery doesn't wipe your internal sd card when you performed factory reset (means all your pics and music are still there) while in some other erases all and you will be left with nothing..just like how you first received the device from store.
Further down, if you flashed any custom rom on your device and you do a factory reset. It won't wipe away the custom rom that you installed, it will only set it back to the rom default settings. To get it back to the stock manufacturer rom, you must flash the official rom released by your device manufacturer. I hope this will clear your confusion.
thanks

I am bumping the post instead of openning a new one - because it is the same question.
You wrote that Factory reset will not wipe Photos, Music etc.
Did you mean that if I saved it on external SD? Because in Nexus 4 there is no option to add SD card.
My question:
1. In my nexus 4, when doing factory reset - it erases EVERYTHING include Photos and music. so please help me understand.... cause I am confused. Does it reset everything or not?
2. In nexus 4, where is the option to Wipe data? I see only "Factory reset". In recovery console?
3. Any differences between Factory reset from the settings, to wipe data from Recovery?
thanks!

1. We do not have external sd in nexus 4. There are 2 types of recoveries; stock and custom. Stock recovery is what you get when flashing factory images while custom recoveries are twrp/cwm. In stock recovery, factory reset delete everything on your device. Everything in your internal as well. It will wipe clean your device. For custom recovery, it won't clear your internal sd storage so your photos/music/docs/backups are intact. It will only delete data partition which stores your downloaded apps. I hope you are clear on that now.
2. Factory reset=wipe data. In every recovery, it's the same.
3. No, it uses the same command so basically there is no difference. Depends on the recovery you use, factory reset on stock recovery deletes everything while on custom recovery sd card is still intact.
The answer that explained everything for me - is that there is a different between wiping data from Stock recovery to wiping from Custom, so now i get what you mean!

Flash rom and keep apps and data
Hi. Is it possible not to factory reset/ wipe data when flashing a newer rom? The reason I am asking is because I want to flash Lollipop on my Note 3 as Samsung keeps forgetting to send it to me OTA or via Kies. But I don't want to lose all apps and data. Thanks in advance.

Hey. I have 1 question. I have pictures, music and videos on my Internal Memory, and I don't want to lose it (I didn't back it up anywhere and I don't have an SD card). Will Wipe Data/Factory Reset delete those stuff, or just apps, settings, etc?
I'm using S4 Mini i9192. I also have Philz Touch Recovery.

I have not used Clockwork recovery for a very long time now so I don't know how it works nowadays. But last I used it, factory reset in cwm (philz is a modified version of cwm) does not result in complete wipe. It will leave out the sd card partition. But like I said, it was very long time ago. Make a backup of them if it is really important. Well, in my opinion, everything needs backup. Even things in your computer needs a backup.
p/s: Try to ask this in S4 thread. Here, we (nexus 4 users) mostly use twrp as cwm is discontinued for quite some time now.

Contacts lost

Hi, there's an issue I have with my Nexus 4. I originally was on franco kernel, and tried to flash a different kernel, and it was giving me a boot loop, so I reflashed franco, but wiped data too, not only dalvik and cache.
Now, the phone booted completely, but it's in a state where my contacts were close to 3-4 months ago, and going to Gmail, and restoring contacts from there does nothing, as on gmail it's also the same situation. Is there antyhing I can do?
Does it have anything to do with wiping data? Although I did this also while having custom roms, and contacts weren't suddenly deleted for no reason!
Thank you in advance!
Hi,
Yes it has to do with wiping data. Your contacts were in data partition, so when you wiped it you deleted everything within it! You have the contacts from 3-4 months ago because it was probably the last time your Google Account backed up it.
I don't see why when flashing custom ROMs and wiping data before you didn't face this problem, maybe it was backed up... I don't know about there, but here in Brazil contacts can also be saved on SIM card, but I'm unsure if newest android versions still support it, after all last time I used it was with my old X10 Mini Pro.

Hi all, i've searched far and wide to resolve this but nothing seems to work that i've tried. I cannot sign in to add my google calendar to my phone. I'm able to do everything else: get email, get to playstore, etc. As far as I know i do not have 2 step verification setup. I'm on 4.4.2, rooted. When i try to add my existing google account to the calendar i get "couldn't sign in. There was a problem communicating with the Google servers. Try again later."
I dont want to have to do a factory reset if possible.

Clear cache and dalvik cache, and delete data from the calendar app. If that doesn't work, uninstall the app, repeat the clearing procedure, then reinstall. It should work:fingers-crossed:
@ldeveraux thanks for the reply. I tried what I think is the process above but still no luck. Maybe I'm not following what you suggested correctly. I went into the data/dalvik cache directory and wiped it out, cleared the calendar data. But not quite sure what you mean by "clear cache" in the very first part of what you wrote. Can you maybe give me a step by step with a little more info? Thanks again.

You're rooted and have safestrap installed?
1) Go to App info on the calendar app and Clear Data
2) reboot to safastrap.
3) go to wipe menu, advanced wipe, then check ONLY Cache and Dalvik Cache
4) wipe these 2 ONLY, then reboot.
If that doesn't work, uninstall the calendar app, reboot, reinstall the app from the play store.
I have no clue if this will work, but it's worth a shot

Hello again, I added back Safestrap and followed the above and still the same results. I appreciate the effort. Any other ideas out there?? Also I can't uninstall the calendar app. I guess its the stock one that came with the phone. I can freeze or uninstall it with TB but i don't see it available on the play store.

I'm getting the feeling you didn't do this as I explained. You shouldn't delete the files or folders in a file explorer app. It should be done like I explained in SS.
And you can uninstall google Calendar with any uninstaller app or TB, either way. the new app to download is here, so yes it exists:
https://play.google.com/store/apps/details?id=com.google.android.calendar&hl=en

Its possible to clear the cache and davlik cache on stock using stock recovery and without root i thought id note..
