[Q] Can't nandroid backup - it freezes

I can't seem to get the nandroid backup thing working. I'm new to this rooting stuff, but i got i done with unrevoked. I haven't done anything since rooting, but trying to get the damn thing to backup. Everytime i try, no matter if its through rom manager or directly through the recovery menu, it freezes when trying to backup the system apk's. Specifically at either the weather.apk or calculator.odex.
The first time i tried it, it corrupted my SD card! Good thing i didn't have anything important on there though.
Any ideas?

All you need to do is flash a new recovery since yours is ill-functioning.
The best way of flashing recovery is through fastboot. In order for this to work your device needs to be S-OFF. You can do this by using the new Alpharev/Unrevoked tool.
Once you have S-OFF, you can use fastboot commander, to flash the recovery.
If you get into any trouble or need any further help just holla

Okay, i have to S-OFF - seems simple enough with the new tool.
But after that, can you please guide me a little, I'm still completly new to this, and is somewhat worried about bricking when I haven't got a backup

All you have to do is downlaod fastboot commander, and the java jdk for the tool to work.
Then, download the Ra Desire recovery
Once you've got that, but into fastboot (power off, hold back key & power), and plug in via USB.
run fastboot commander, navigate to the "misc" tab, select "recovery" and nothing else and click "erase chosen partition", then go back to the "Hboot, radio & rec" tab, choose "recovery", and find the recovery.img you have downloaded.
Then, simply press flash recovery
Once that's done, power off and reboot into recovery (power off, volume down & power, then use volume down key to navigate to RECOVERY and press power to select)
Then do a nandroid backup.

Okay, I now got all that, and its making the backup, but how long should it take? It's been around 10 minutes now i think, and the screen is almost filled by rows of dots

wow, that's never happened to me... When I backup cyanogenmod 7.03 it takes under a minute!... this is a little strange.. If I were you I'd backup your texts (and apps if you want) and do a fresh install of a ROM (as in with fastboot commander, go to the "misc" tab, and wipe boot, system, userdata, sd-ext and cache then flash a new ROM through recovery), and try again. I've never had a problem like this before.
understand that if you're having problems with recovery now and if it didn't allow you to install, and if you wipe everything you might be stuck in fastboot, and then your only salvation would be a RUU

Well i did everything you said with succes, so i don't think there were any problems there.
I tried again and the backup completed! Thank you very much for your help!

Can't decrypt Galaxy Nexus after OTA

Just applied the 4.0.2 OTA update to my GSM Galaxy Nexus and after the reboot, even though i type in the correct password, my phone wont decrypt.
I read on android forums people with the 4.0.3 OTA having the same problems.
How can i reset my phone? How does Odin work? Somehow i am stuck at the screen with the android and his open chest

ok i got odin workin, needed to install the android sdk, wiping my phone now

Please note: YOU WILL LOSE ALL DATA
everything seems ok, i got into odin mode like this:
-connect your GN with usb to your computer
-start with power + volume down
-use volume up / down to select recovery mode
-confirm by pressing power
-you will see an android with a triangle
-press power and volume
-select factory reset
-confirm with power
-reboot
this worked for me only after i installed the android sdk, before that somehow i was stuck at the android with his chest open and couldnt select anything because somehow my device wasnt recognized
hope this helps

This also caught me out. Not happy.
Method I used (posted on OTA thread) worked without installing SDK:
Power off
Hold Volume + , volume - and power
You should get a green android image with the body opened with "Start" on the screen
Press Down till you get to recovery mode
Press power
Phone will reboot
You will then get same image of android (smaller) with red warning triangle
Wait a minute or two and then press volume + and power (not sure exactly what I did for this maybe it's just waiting)
Use volume down to select wipe data/factory reset and hit power
Select Yes - delete all user data and hit power
Once done select reboot system now and hit power
You are now back to zero and can start again.

Hi I have roote, and installed cwm, I the applied the encryption proces, now I want to flash a ROM (revert to stock) thru cwm, it says can't mount SD card. I try do a factory reset through cwm but also says can't mount....
Any tips on how to remove the encryption?

The only way to decrypt an encrypted phone is using fastboot. Fastboot is a developer tool that runs on your computer. You need to download the full Google factory image or a full rom, and flash all of the files to your phone using fastboot.
CWM and other recovery software will not be able to factory reset the device.

This is not entirely true. You should be able to use TWRP 2.2.0. As well, have a look through this thread.

What is the command you have to type in prompt to do this?
I am also having trouble decrypting my phone. Factory reset it a couple of times and it is still encrypted.

Stuck on Asus load screen

you may want to flash your phone back. so this consist of
1) read up how to access to Temp CWM
2) download and transfer the full rom to your SD card
3) do a wipe all partition and go to advanced setting, wipe cache
4) install zip and choose from external SD, point to that .zip file for the full rom and apply.
5) installation may take 10min or so do not switch it off. after installation you are good as new.
I believe this should solve your problem, normal if things get bricked is due to config file error could be [syntax, corrupted, missing, setting].
Flashing should solve mostly of it unless the file that you previously accessed require root and cwm does not give permission to the file. that is a permanent bricking.
As always, newbie should not try tweaking permission required files, you end up having bricking the device as there might be no solution to recover it due to access rights. ALWAYS have a back up file so you can at least copy the file back and chmod it.

my problem right now is my pc wont detect my phone. Ive already installed the drivers.

Same thing happened to me when I tried flashing the OTA update with my phone being rooted. You have get into recovery mode on the phone and then use ADB to put the original image back to the device to get it back to stock so it will reboot. It worked for me

here is the stock firmware.
https://www.asus.com/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
its fine if your phone does not talk to your PC now. copy the firmware to your SD card via other means. [card reader etc]
then try my method of flashing it back to original state, you stated that adb dont work, have you tried the temp CWM method yet?
the main goal is to wipe dalvik cache under advanced menu in CWM, and cache partition and all hard reset.
then you flash back your original file.
hope it works for you.

ive read about the temp cmw method and i cant figure out how to go about it. it says on the instruction that you need to turn on phone before running the cai_dat_CWM. how am i going to do this as my phone will only boot to the asus logo? thanks

just figured it out. I need to boot in fastboot so the phone will get recognized. However, the latest build available on the asus website is still 2.17.40.12. I already have the 2.18.40.12 version. The 2.17 firmware can't overwrite the newer build in temp CWM recovery. Anybody knows where i can download the full rom? Z00A-WW-2.18.40.12?

Always make a backup of the current (known good, working) ROM in TWRP, before flashing a new ROM. That way, you always have an easy way to restore to stock or the previous working ROM, if something goes wrong.
I'm always surprised at how many folks skip this step. It should be a cardinal rule for any rooting, ROM flashing, etc.
But I also don't think that returning to stock would solve your issue. I think your internal storage is corrupt. I assume you don't have any data you want to try to recover (it probably can't be retrieved at this point, anyway)? Boot into TWRP, press the Wipe button, then select the "Format data" button. Don't mess with the Advanced button (and wipe options therein) unless we tell you.
After format data, reboot and see if the issues with writing to storage is fixed, and let us know.

HTC devices don't have download mode. It has hboot (bootloader) and you can select fastboot mode, or go to recovery from there. But no download mode.

okay so i followed the steps you gave me and was able to download to my internal and load another rom onto it. also it wasn't me who had wiped the phone entirely it was the person i got the phone from he said he wiped everything on twerp except the system..........which in itself was stupid cause that means you wiped everything on the phone from the recovery options to basic system stuff. i am now running bliss pop v 6.2 i think but i may chage that to cm 13 due to an error for Pokemon go , King Tongue, and YouTube Vr. Pokemon go and Youtube vr gets a blue circle in the middle of the screen and keeps you from playing the game or using your onscreen buttons to leave the app the only way to leave is to put the phone to idle mode (press the power button) then unlock the phone and then quickly press the home button.. but you have helped me with my issue thank you im to use to Samsung and Lg lol.
P.S. Do you buy any chance on how if i ever wanted to go back to stock on how i can do so ?

I don't know what you mean by "recovery options to basic system stuff". By not wiping system, the OS is kept fully intact. All the other options are various forms of user data.
But yes, wiping most/all the options in the TWRP "Advanced" wipe section is foolish. Folks often will do this, which wipes the ROM they want to flash, TWRP backups, and even system itself (then wonder why there is no OS!).

I do know, but I can't tell what "stock" is for your phone, besides that its Dev Edition. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

I get the fast-boot thing but where is the option for the getvar all? is it in the first option after doing the button sequence power+vol down or after choosing fast boot?

fastboot getvar all is a command that you put in your PC, in CMD... you must have fastboot and adb drivers installed

Accidently deleted Android OS on HTC One M8

I was trying to load Lineage onto an old One M8, I had just cleared the system, cache and data partitions using TWRP. I then clicked reboot, which I now realise was a mistake. I am now stuck on the HTC logo screen, none of the physical buttons are responding, so i cannot get into bootloader etc. I can't send ADB commands to it, it won't show up on windows file explorer, I can't even turn it off. As is said this is an old phone so I am not worried about losing data, which is probably just as well at this stage!
Any advice would be appreciated!

The physical buttons will respond, but you need to hold them for a pretty long time in the current "stuck" state. Do this:
1) Hold vol up button and power button, until the phone restarts (may take about a minute in the current stuck state).
2) Once the screen goes dark to reboot (but before the HTC logo screen appears again - I think you have 5 seconds or so), let go of the buttons, and only hold the vol down button. Do not let go of vol down, until you see the bootloader screen.
3) If you fail to get to bootloader, you simply got the timing wrong. Either started pressing vol down too late, or you let go of it too early. Simply repeat steps 1 and 2, until you get to bootloader.
4) Once in bootloader, simply select recovery, which will boot TWRP. And flash Lineage as you originally intended.
A note on wiping system when flashing a ROM: I know some folks will swear by this, and some guides will tell you to do it. But it is not necessary, and as you've seen can cause some complications. Nothing that isn't easily solved, but may give you headache nonetheless (like this case here).
The ROM install script will wipe system before it installs the custom ROM. So doing it yourself is redundant. And in the case of the ROM fails to install (it happens) you are stuck without a working OS. My recommendation is only to wipe cache, Dalvik and data when flashing a custom ROM (the default wipe in TWRP).
Any perceived "benefit" from wiping system is usually a placebo. In the rare event that the custom ROM fails to boot (or some other issue), you can always go back and flash again, wiping system (as a troubleshooting measure, etc.). Of the years of flashing ROMs (dozens and dozens of times) on various Android devices, I can count maybe 2 times where I felt I needed to wipe system when flashing a custom ROM.

This can be expected when "stuck" on the logo screen. adb will only work when booted to a working OS, or alternately when booted to TWRP. Same thing with MTP access (File Explorer).
