Root [Solved] device wont complete boot!!!

[davidmargolin]

phone died today while on the road... when i plugged it back in, it charged fine... turned it on and it bootlooped... tried formating cache, dalvik... still wont boot...

also if it helps, things during the boot animation are weird...

usually the capacitive lights are off
then a vibration can be felt
then capacitive lights go on...

this time it begins too boot
lights are off
then lights go on without any vibration
boot animation never ends

anyone have any ideas??? rom is mobster v4 and using anthrax but i doubt its the cause of the prob... though willing to flash a diff kernel if needed.... lots of important info and no backup made beforehand...

update:
another kernel does not fix it

update2:
tried to get a logcat but cant seem to get it...
when off, device is recognized as 'recovery'
when turned on, device is not recognized and doing 'adb logcat' leaves me with this message:
- waiting for device -
but device never boots and therefor a logcat is not created....

update3:
switching bootloaders (i went to virgin mobile stock 1.57) changed how the capacitive lights reacted but still didn't help the bootloop...

Is it possible this could be an.hboot issue?
I don't know but I would try reflashing hboot, easy enough anyway

ok... at this point i think ill just reflash the rom but does any1 know if i can get back app data from my nandroid backup??? restoring data causes a bootloop so i need an app to extract the app data...

also i would still like to know what the problem could have possible been because this happens to me quite often on many diff roms and not just mobsterrom...

 

[BackHandLegend]

Could it lie with the recovery you're using?

4ext??? can i use backups made from 4ext with clockworkmod???

 

[BackHandLegend]

Well I'm not entirely sure that its 4-ext. But I remember getting these all the time when I was S-On. It'd be fixed using fastboot but NEVER trust clockworkmod for anything on any phone lol. But I don't think that backups are interchangeable between different versions of recoveries and different recoveries altogether.

 

[OverByter]

BHL is correct, nandroids aren't usually compatible with different versions let alone different recoveries.

You could use Aroma File Manager from recovery after you restore your data partition to copy off the files and directories you need to your SD card. I believe TWRP2 has a file manager built-in but I've never used that.

When users have had weird problems on the Evo 3D it usually helps to flash the RUU.exe in it's entirety, then flash a custom bootloader and recovery and restore a nandroid or flash a new ROM. Since there's no RUU with the OTA updates yet, I would download and install the OTA as well right after the RUU.exe completes.

thanks for the file manager link as it will become usefull in the future but at this point i can see it bieng used to pull the app and app data folders from the data partition but restoring everything on a freshly flashed version of the rom would just take too long... what i really meant by 'pulling app data' is that im looking for an app to restore my app data from my nandroid... i heard titanium backup can do that but need confirmation...

 

[BackHandLegend]

Well you'd boot into fastboot. On your computer install miniSDK, then after that download any rom or kernel that has a boot.img in it. After that hold shift and right click in the mini sdk tools folder, then select "open command window here" type in "fastboot flash boot boot.img" in the terminal or command prompt.

(Make sure you have the right drivers installed)

Based on what you've stated above, I suspect that your nandroid backups are still good and you should be able to restore and boot them once things are cleaned up. IMO, the RUU approach would be worth a try as I've seen it work for a number of users with booting problems on the Evo 3D. The piecemeal updates tend to get things out of sync after a while.

That's because you have hboot 1.57 installed and the bootloader is locked. Install the JBear 1.57.5757 hboot and you should be able to run those commands.

reflashing the rom will get me to boot up again... booting is not the problem... i just cant afford to lose all my data... a ruu wouldn't help in this case

just when i need a diff hboot, xda decides to go down for maintenance... just my luck 2day

I guess I misunderstood your OP. It sounded like you weren't able to boot without loops. If you can get into recovery and do an advanced backup of data and restore it after installing the same ROM that should restore most of your apps and settings.

Maybe I'm still missing something? I'll go back and read your previous posts again.

What do you need? I have all the hboots.

Edit: The JBear 1.57.5757 hboot is attached.

Damn... this one is a toughy... This is risky, but then again there's barely any options.

Backup current rom on both 4-ext and clockworkmod.

Flash RUU

Reroot, unlock bootloader.

restore backup

Then use fastboot command once again.



OR you can do this. (more work)

Backup current rom on both 4-ext and clockworkmod.

Flash RUU

Reroot, unlock bootloader.

S-Off device

Downgrade bootloader

restore backups.

Try his method first it look promising!

Are you running the terminal and whatnot as an administrator?

sorry... my horrible explanation... lets start again
hi im david
s-off, on jbear (now), running (but not booting) latest mob rom
my original plan was to backup data fresh flash rom and restore data
this didn't work... rom wouldn't boot... guess the prob is in my data

i can def flash a diff rom and set everything up again...
but this time around i had some very important things on my phone and i really dont want to have to do a fresh install
so i need help either getting it to boot or to get my app data back alive without actually restoring the data using 4ext...
hope that clears things up a bit...
sorry for the confusion



oh and i got to flash the boot.img by getting jbear but the rom still wont boot.... fresh flash prob will boot but again, i cant risk losing everything i had on there (lots of important school stuff)...

OK, gotcha.

I've had that problem before when I flashed Leedroid Tweaks before a nandroid and then tried to restore to a ROM without LT. Did you have any mods installed on the ROM you were using? If so, can you recreate them before restoring the data partition?

nope nothing... no mods this time around...
also had this bootloop prob before (on many roms and not just mobz) but didn't really care much... just started from scratch those times...
