What happens when you downgrade? - Droid Eris Q&A, Help & Troubleshooting

I have 2.1 leaked... What happens if I try to put Ivans Rom on my system? Will it wipe everything on the phone or just give an error?
thanks

if you have the 2.1 root, and you go to another rom, and if the other rom is 2.1 base with sense, you should be fine and not have to wipe data. If you are not root then you have no chance right now to install another rom.

u dont have root so u dont have read/write permissions only read. if u try to push anything into the system folder it will say "permission denied read only file system". i hope this is what u r asking.

thanks, thats what i was curious.. just if all my data would be lost or phone would be fubar after the attempt..

You wont lose any data. nothing major will happen if you try and do that. like said above, it will say permission denied... meaning you dont have root access, so no filee / data damage will be dont. unfortunatly there is no way to get root from 2.1 leak.

Edit::
Yeah it.looks.like u will either need to push slacker to /system
Or u might have to sbf.
Just FYI-- Sbf will not wipe ur data away if that's what u r worried about.
BUT if u bootloop after sbf u WILL need to data wipe.
I can't day for sure whether or not u will bootloop.
I never bootloop after sbf UNLESS I have mods or tweaks or custom rom installed

Use root explorer
Go to data/app
long press slacker.apk(might not be the exact name but u should see the slacker icon next to it
choose "move"
Navigate to /system/app
Press the grey button at top of screen that says "Mount r/w"
Press Paste.
Reboot.
U can also use other file explorers as long as they have root abilities and u can mount /system as r/w (read/write)
Root explorer is simplest and easiest to use IMHO for this

Then u need to download it from market
if u have it installed from market
it will show up as com.slacker.radio-1.apk in /data/app
I don't know if this would work anyway beings the STOCK slacker may be slightly different. I.e. signed by moto or something.
in which case u will need the slacker.apk from a stock x2 system if anyone running stock could copy it for ya and upload. And u also may need the odex file if it has one.

Go take a look at /system/app real quick.
U will see that some apks have a odex file beneath it.
They allow quicker access to apps by having bits of code readily available to system or something similar to that.

First and foremost, have you tried downloading the 2.3.5 zip file again? It's telling you that is has an error in the update.zip file, so it's probably a corrupted zip file.
Go here and get the OTA 2.3.5 update and push that to your phone -> http://forum.xda-developers.com/showthread.php?t=1341202
If Eclipse is boot looping, you need to go back into recovery (I would suggest the stock recovery, but BSR is fine as well) and wipe data, cache and dalvik cache. Any time you flash a new ROM, you should always do that before rebooting.

my phone gets root access from pre-rooted custom roms. when i first rooted my phone i used super one click. after switching from comfortstock rom v3 to adrenaline rom, i still get the superuser icon. however, i am unable to directly delete files using root explorer, copy or even move files from and into system app. when i look into init.d folder, i am unable to see permissions. in titanium, i cant see the memory usage for a2sd. what can i do to get it back?
Reflash the rom......
You know you are rooted when you use XDA more than FB

I already tried reflashing. However, perhaps there was something i did wrong. I did not do all wipes and stuff. Let me try reflashing it again. One more question, when I do restore via titanium, should i restore system apps and its settings? Maybe thats where I got this error from.
EDIT: all wipes, data, cache and dalvik, reflashed rom. was able to regain super user permissions. thanks all for the help. though still unable to see a2sd usage on titanium. but all is good.

Yes, new rom replace all things
well since you have already done factory reset (and lost all your data) no point in whats written below
But if it happens next time and you want to preserve data, please mention if you are running an odexed/deodexed rom. Someone nice here can upload the file(s) you need and you can push them to your phone using adb

Yes stock rom will always be odexed. to check you can go to app or framework folder in system/ and see if you have corresponding odex files for apk or jars.
Edit: Also a suggestion. Don't flash mods that do not specefically say that they are for odexed roms (if you are on stock). For brightness control you can use lux brightness free from market. it gives you control on how much brightness you need
One guy from local forum gave me a restore zip file. Any ideas how can i push it on phone, if it loads only in cwm and download mode?

Some Basic Q/A related to rooting

Hi!
I've been wanting to root my Canvas HD for the past month but did get success with sp tool..So I'm gonna try the Motochopper method which has reportedly high success rate... but because that tut was not very detailed, I have some doubts.
•I wanna know if I follow this method will I lose any data, app data, game progress, contacts etc etc.? And if there is a chance of that is there a way to backup these things? Apps like titanium and nandroid require root access which I don't have.
• When trying out the sp tool method some people reported that they lost their IMEI no. after rooting which is clearly a very serious issue and I don't wanna end up like that so does this method poses the same threat? if it does, is there a way so that I can take a backup of my IMEI no.??
•Do I need to take out my memory card/ battery?
Note: I am a noob in android rooting and stuff so please don't be harsh. I am currently in middle of the process
Thank you any help is much appreciated :fingers-crossed:

You won't lose any data or IMEI and there is no need to take the battery out. it's not like flashing an entirely new firmware. i assure you it's very very safe.

YES DUDE OPEN SUPERsu ... yes allow it to update binary su.. actually supersu is an app which grants all other root apps to access the root files ... it is the app in a crude language the main head to control root access ok !!! or in other words in 99% cases it proves that device has been succesfully rooted !!!!!!!!

Hi Vemajai,
Removing Boaltware is a kind of hit and miss.
The way i do is
1) Open ES file explorer
2) Click on Root Explorer
3) Mount Write Permissions
4) go to /system/app
5) Cut the Apps that I dont need and paste them into any folder on external card.
6) Go to CWM recovery, wipe cache, wipe dalvik cache, and fix permissions.
Choosing the apps to remove/delete is important, you can search internet to which apps are safe to remove, but it will be device specific.
There are few scripts available on the xda that do this job automatically, but we dont have one for our A116 (correct me if i am wrong).
If you remove a wrong apk accidentally, you can end up with FC's(Force Closes) and few functions or apps may not work.
So its better to have a Nandriod Backup (can be taken using Recovery like CWM or TWRP) so that if some thing goes wrong we can go back to working state.
-- I am not responsible if some thing goes wrong with your device, do the above at your own risk.

Cant remove bloatware

Ok so long story short i downgraded to 4.3 rooted then OTA updated to 4.4 (using survival mode with supersu to keep root permissions)
installed romtoolbox to uninstall the crap but it wont remove the bloatware.... i dont know why flashtool says i have root access and roomtoolbox gets su permissions.... so i dont know what is wrong??
any help would be splendid!

That means you cant write to the system partition (delete need write permission).

You only need root on your phone, then run the recovery installer on your pc and it'll do the rest of the work. ADB drivers must be installed don't forget that. instructions and download here, read them carefully and you should have write access in no time.
