I am relatively new to flashing ROMs & kernels for Android. Currently I'm using MIUI 1.5.6 and would like to upgrade to the newest version of 1.5.13.
My question is, do I have to wipe data if I'm just upgrading to the same ROM or would wiping cahce & Dalvik cache be sufficient?
Before anyone flaming me I have searched the forum prior to posting and surprisingly didn't find anything useful as I thought this would be a frequently asked question.
Thanks in advance!
I never clear if i'm gonna do the same rom and it seems to work perfect. So I'd say dont it takes less time but if your worried do it. clearing that stuff wont really loose anything so its your choice really
I think you ALWAYS should do a backup, just in case something goes wrong.
You have the device at the Computer, you have the cable hooked up.
What would it take... about 5 minutes to do the backup up ??
oddball69 is right. You should always do a wipe.
Just to avoid problems
Most of the Devs will specify for each version if a full wipe is not required. If you can't find anything about it then do a full wipe.
If they directly say a wipe is not required then it's probably just some small fixes.
Thanks for all the responses.
I was going to do a backup for sure I just wanted to avoid having to wipe everything and then reinstalling and re-setting up all my apps which could be quite a pain
Depends on the ROMs used, usually the developers state if this is necessary.
It wont hurt if you try without wiping, if it makes problem just wipe and do it again.
What is there to loose?
If I install a new rom without all wipe written guides, and risk the "brick" or simply the need to do later? I do not want to reinstall all applications, I am going to install a new rom, and I am afraid of my phone unusable. Thanks in advance
Notes: translation with google translator, and I wanted to post here ^ rom, but being a newbie I can not. With regard to questions like, did not answer the question "brick"
If you install without wiping the cahce, Dalvik cache, and data, then you run the risk of your ROM not working properly. It's pretty hard to brick your phone. If you don't want to trouble with reinstalling EVERYTHING then I suggest you check out Titanium Backup Pro in the android market, it will help you out a lot. It can backup all of your apps as well as the data with the app, your contacts, wifi connection points, etc. Not only will it back up everything, but if you buy the pro version, it will also install everything for you as well (Automatically of course.) It takes seriously like 20 minutes to get all your apps back, and and usually it's a bit shorter depending on the amount of apps you have. As always though, before flashing a new ROM/Kernel/Radio etc make a complete Nandroid backup in CWM.

When I first installed a custom rom without a wipe it worked well, for about 3 minutes. I would get random freezes in which the only way to get out would be a battery pull. I eventually thought I broke my phone (since I was a noob) and flashed a return to stock package. End of story, wipe before flashing!

If your not prepared to do all the needed steps to flash a custom rom then maybe you shouldn't be flashing roms.
Hi smart people!
Just to throw it out there, I am not very tech savvy so excuse me if I misuse terms and such.
I believe I completely bricked my phone (I hope I'm wrong). After I downloaded Cyanogen through ROM Manager, my finger stumbled on the "continue" or "next" button or whatever WITHOUT checking the boxes to clear data, etc. I believe this is where I went wrong as I think I followed all other steps correctly (fyi I used the one click recovery flasher and made a back up).
Now when I turn on my phone, it goes from the stock LG loading screen to a modified LG loading screen (Cyanogen's I'm assuming) but it gets stuck there.
I've been searching on the different threads for quite a while and pressing the different combinations of volume up/volume down/power don't seem to do anything. I cannot get to the recovery screen.
Please help! I will forever be indebted to all of you. I am stupid and shouldn't have tried to do this on my own. Thanks in advance
What you will need to do is flash CWM via NVflash then boot into CWm and install your ROM.
If you flash CWM via ROM Manager it causes problems like what you're describing, I know from my own experience of following a friends instructions and doing that then having that exact issue. After getting my phone working again I then started to frequent the boards here.
As soon as I read the first couple lines I saw rom manager and saw the problem, you to search something that you have typed out all within this thread... I'm not near a computer but you should just search through these threads and you find your solution in detailed description. You need to get recovery from nvflasher just search that

Hey guys...on step #10, it says to "select 'have disk'" but i do not see that option in the list.
Thanks
okay now i realize i should have been doing the cwm recovery. sorry guys and thanks again
reboot error
hey guys,
I successfully was able to boot into cwm and then i restored a backup from yesterday. however when rebooting, it displays the LG logo and then the screen goes black and the back light flickers on and off. not quite sure what to do now...if you guys could let me know what i should do or post a link to another thread, i'd really appreciate it. i honestly have been going through other threads but i guess i'm just not competent enough to know which directions apply to my problem.....
thank you..hopefully this is the last time i'll have to bother you!
The back-up could be corrupt and since the one time I had a problem with a nandroid was when it was created after ROM Manager sent the info to CWM, that's likely the case. Just redownload CM7 to your SD card, along with Gapps, wipe system, data and cache then flash CM7 followed by Gapps.

Have you wiped everything before restoring your backup through CWM? If not, boot into CWM, wipe data/factory reset, go to mounts and storage, format system, then go into advanced options, wipe delvik cache, then restore your backup.
I'm guessing you did a backup through rom manager, so if this doesn't work, you'll have to download a rom of your choice from the development section of this forum, load it onto your sd card through CWM although this is not recommended but you won't have any other choices, (to mount your sd card in CWM, go to mounts and storage, mount sd card), then wipe everything as mentioned above, then flash the new rom.
Or you can follow the instructions on this thread http://forum.xda-developers.com/showthread.php?t=1248644 to flash 2.3.3 via nvflash to get a working phone for now until you learn how to properly flash custom roms.
Hope this helps
P.S. for future reference, you did not brick your phone, you got stuck in a boot loop, you know your phone is bricked when you don't see anything on the screen when you turn it on, usually it's just a software issue, but sometimes it could be hardware, for example I burned the motherboard on my previous android phone trying to customize it lol

He's already flashed CWM the right way, and tried to restore from a nandroid. I already mentioned getting a different ROM, he's already stated that he got this all started trying to flash CM7. Please read the posts which have already been made, we don't need the same information being posted again, if someone already posted something and you feel it needs clarified then clarify but from what I can tell you read one post and that was it.

I really hate posting anything that doesn't have to do with anything phone related but I just couldn't stop myself from replying to your post!
1) I actually read all posts in the thread!
2) I did not in any way suggest that he didn't flash CWM the right way, I merely asked if he had done a full wipe before restoring his backup!!
3) Your reply was submitted while I was typing mine, so I'm sorry I didn't check the thread again before submitting my reply!!!
4) I'm well aware of what he tried to do already, but thanks for repeating it!!!!
5) If YOU read all previous posts you'll notice that my post does not exactly replicate any other, there's some new information in there that the OP might find useful!!!!!
6) From what I can tell, you need to work on your english and comprehension skills!!!!!!
To the OP, sorry for trolling your thread with this post, but I just couldn't help it, and to Bonk I hope you'll be the mature one and not reply to this post.
Is that to say you're immature? If one were to judge by the number of exclamation marks you have I'd say yes.
The only "new" thing was asking if he wiped before the restore, which, at this point, would be useless to ask as I already told him to make sure to wipe.
To the OP: How goes everything thus far?
thank you
that's what i ended up doing and it worked. thank you so much for all your help!

And dalvik cache for good measure, even though it is stored on the cache partition and will probably get wiped when you wipe cache. Sometimes it's good to overdo thing's.
Unable to do anything!
Well i was playing with the phone, rooted and kept playing with different ROMS till i would have found a good stable one, but something happened, I ended up not being able to use any functions in cwm (apply update from..., backup and restore, install from zip). I wiped data/factory reset, cache partition, dalvik and i have the ROMS inside, i can see them in CWM. just can't read them. or any zip i use. what happened? is this bricked? if so do i have to go from scratch with the phone and use SDK?

UNROOT help
Hello again smart people,
I was hoping we would never meet again (for the better) but unfortunately i must unroot my phone to receive work emails. I have tried unrooting my LG G2x multiple times but to no avail thus far.
Here is the process I have tried:
1) boot into recovery - wipe cache/data factory reset, wipe cache partition, wipe dalvik cache
2) restore - using stock rom i found online
3) flash stock recovery image using nvflash
4) (attempt to) unroot using superoneclick - AFTER GOING THROUGH MULTIPLE STEPS, IT SAYS "TRUE" UNDER "CHECKING IF ROOTED". (also, i know it is rooted because it says the phone already appears to be rooted when i try to root again).
Do you guys have any idea what the issue could be?
Thank you in advance...
Hi!
I installed the latest SlimBean on my i9000, I came from CM10.0. It all went smooth, but when the OS started, I was quite surprised: all my old apps from CM10.0 were still installed!
I'm not sure whether this is a bad thing or that a complete clean install is more preferable? I think it was kind of handy, but maybe other things remain as well and make the system go slower?
I followed the official steps exactly:
From another JB or ICS Rom to SlimBean
Download device_x.x.zip, slim_gapps.zip.
Enter CWM, wipe data, format system ( in mounts and storage)
Flash Device_x.x.zip***, then MUST flash slim_gapps.zip (other files optional)
*** - If the flash is too quick ( < 5 seconds or so), reflash device before flashing common or other zip files.

Furthermore: do you guys think there is a lot of battery life gain with this SlimBean OS?
Thanks.
You should always wipe data when switching ROMs

I think you forgot to wipe data which is a "dirty install" and sometimes everything will work with no problems and sometimes you can end up with countless little problems. The more closely related the two ROMs are, the more likely a dirty install will be head ache free. Just remember if you do a dirty install and end up with problems, that you shouldn't report them as bugs until you have tried a clean install (wipe data, wipe cache, wipe dalvik cache).
Changes in battery life will depend a lot on how you use your device, so it is best for you to test it yourself. I noticed that you mentioned that you have a i9000, the best place to get questions answered about that device is here: http://forum.xda-developers.com/forumdisplay.php?f=748
I am quite ashamed of myself, sorry guys. The "problem" was that Google Market automatically downloaded the apps that I had installed on a previous installation because they were "my apps" and somehow Market thought I wanted them in my fresh install :S Thanks...
Problem solved - Thread Closed!
i dont use this forum as i have a different phone and i dont particularly want to sift through every thread to find an answer so i thought id ask to find out for myself
my partner owns a stock unrooted totally unmolestered original moto g running android lollipop and earlier today it started to lag and flashed up with an error she didnt have time to read, not long after it completely froze so i tried to turn it off and on again. after trying to turn it on again it has gone in to a bootloop and will not start properly.
any help on a solution would be much appreciated if anyone can help me ASAP.
cheers
Boot to recovery and try wiping cache. If that doesn't work, you may have to do a full wipe which means losing all files on the phone.

any guides on how to wipe the cache without rooting it? im assuming id have to use fastboot or adb or whatever but the internet hasnt exactly helped me with any solutions
Just wipe by booting into stock recovery.
