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?

just a quick question, do you have to wipe your phone (alt+w) everytime theres a new rom update? for example if going from JF ADP 1.5 to JF ADP 1.6, do you need to wipe phone before applying the 1.6 update? or is it only necessary to wipe if your going from different roms for example JF to Haykuro..etc..etc
thanks
anyone have an answer to my question?
I'm curious as well. The impression is that you do not as long as you've wiped when you originally rooted.
I'm sure the safe answer is yes, you should wipe but that's a pain in the a**.
You should wipe IMO.
If you don't wipe and run into esoteric issues most likely you will be asked to do so anyways as it is the only useful troubleshooting tool most of these people have because
1.They don't know any better (no ones fault)
2.They don't have time take a look at your debug logs and then instruct you through some most likely intermediate-advanced commands to fix the issue.
Say you moved into an apartment and it's filled with the last occupants stuff. There's a blood stained sofa, stacks of magazine around the WHOLE apartment and a dirty toothbrush. Are you going to be comfortable sitting on that sofa? Would those magazines get annoying? Would you brush your teeth with the dirty toothbrush?
If you have to walk 10 miles, do you wear your own shoes or the last runner's leather shoes that are two sizes too small? If you can even get the shoes on you, you're gonna be in pain and give up within the first mile.
^_^
My answer is: Always wipe. Let the new OS use his own shoes.
ok i understand where you guys are coming from, but what if its only a small update to say JF ADP 1.6, and you are on JF ADP 1.5, it wouldn't make sense to do a wipe just for a small update. am i wrong here. now if ur going from JF to Haykuro then a wipe is definitely necessary. I read somewhere before, that mentioned you didn't have to wipe if you were staying within the same rom. i guess i just need a better understanding on this.
See the quote in my signature
hahaha! ok so I guess I will wipe before applying any new updates. what about the JFupdater app, it says it applys any updates, i dont believe the app wipes your phone before applying it, so is it best not to use the jfupdater when flashing an update?

My suggestion is generally this: Try it without a wipe. If it works, then great, you keep all your stuff the way you had it. If you run into issues that seem blaringly obvious(home process crashing, many force closes, boot looping, etc) then go back to the recovery image and do a wipe. There aren't any problems I know of caused by not wiping that can't be solved by going back and doing it after the fact.

thanks! thats exactly what i was thinking but wanted to be sure.
now wiping wouldn't mess up any links to the sd card(apps2sd) correct? wiping basically justs wipes the data from the phone....i guess what i mean is would I have to set up apps2sd again?
i'm with marcus, if you can get away with not wiping great, if not oh well wipe. or you could perform a nandroid bakup and then wipe, then after the update just fastboot flash your data.img

You would only need to restore the symlinks (if that's the method you were using).
Hey Guys,
So I just rooted my Thunderbolt the other day with Cyanogen 7 Mod version 7.0.0. Today a new update came out (version 7.0.1) and I was trying to figure out if I needed to wipe my data and cache in order to update to this version. Hopefully someone has the answer. I am new to android and am looking for advice. Thanks in advance!
Wipe data
Wipe cache
wipe dalvik cache in the advanced portion of CWR
then install the ROM
Do all three at least 3 times just to be sure.
Make sure your battery is fully charged.
Anytime you install a new ROM follow this. If a small modification like new market, pull down menu. just wipe cache
Hopes this helps

Lol, reminded me of the website is down vid....did you reboot? Yea man I rebooted three times, I always reboot three times like you told me!
-sent via 1.21 giggawatts of android.
wipe 3 times? excessive much? once is sufficient and additional wipes wont do anything more.

+1 to wiping just once.
Also, OP, keep in mind CM7 for TB is pre-alpha and does have bugs. If you're looking for a daily driver, since you're new to Android, perhaps you would want to try a more stable ROM to get your feet wet, and once you get the hang of things, perhaps trying CM7 or a leaked ROM.
Good luck!
Wipe 3 times Anal retentive much? ...haha anyway
Wipes of caches sure but ....
Flashing CM7 7.0.1 over 7.0.0 there is no need for data wipe .
If an issue does arise you can wipe it after but why reinstall all your apps really?
This has been my daily driver
No 4G here yet & I use do not use wifi regularly.
are there still issues with CM7 not being able to use phone information (EPST) or ##778# to manage / edit modem settings?
i think i'm stuck on 3g...
there's an app called network that lets you pick which radio you want to use..I used it to switch from 3g/4g to 3g only...it has 4g only.
I always wipe 2-3 times ever since the OG Droid days. It takes you 30 more seconds, whats the big deal. If it somehow bricks because the wipe wasn't successful or you have to reflash a rom it will take you another 10-20 minutes.
Better be safe than sorry.
I've followed the steps outlined in the following thread but i can't get data to stick. It frequently drops even the 3G connectivity.
Also noticed that bluetooth isn't workinig.
http://forum.xda-developers.com/showpost.php?p=13881413&postcount=2616
Any tips on what I can try to get data to stick.
Hey all, long term lurker here posting, obviously, for the first time. I'm not sure whether this would be better placed in the general or q&a section, as it seems like a good portion of the general section consists of questions.
Anyways, on to the problem. I recently attempted to flash the mr1 version of CM7 and was greeted by a force close loop, with com.android.phone closing. This was after wiping the dalvik cache and all data before flashing the rom. I was actually getting into a bootloop before that, even thought the md5 of the rom matched up with the one posted. I had redownloaded the rom to try again, and managed to actually boot before running into this fc problem. I have no idea what could be causing this, and it would be great if anyone could offer up some ideas on potential fixes, or at least some insight into what might be going wrong.
What radio are you using?
As far as I know, the stock radio. I don't remember ever flashing anything other than some of the early thunderbolt cm7 builds. Radio version is 1.16.00.0223r.
You have the correct radio (you can use 223r or 402w for MR1 version). Did you wipe /data, /system, /cache, /dalvik-cache?
I believe I wiped all of those. I know for a fact that the dalvik cache got wiped, and I'm pretty sure I wiped /system and /cache

I'd recommend wiping and flashing back to a Froyo ROM (BAMF is always a good choice, just make sure its not one of the new Froyo mr2 ones), and then attempting to wipe and re-flash CM7. Sometimes these things just happen. If its just a little bug, this will fix it. If theres a deeper issue, we can do more to expose what exactly it is, but lets go in baby steps

I'd agree but me personally I'd just do a wipe of /system, /data, /cache, /dalvik-cache and reload the ROM fresh over a clean system. Once you do that and load up gapps see if you have any issues before reloading apps. It wouldn't hurt to return to a FroYo ROM just to make sure things are good though as well.
Try clearing data on contacts storage, phone, and media storage, for some reason one of those worked for me
Thanks, I'll try your suggestions and see if they get anywhere. @MattBeyers, I'm currently on the stock sense rom (or whatever you end up on after rooting), so would you suggest I flash another froyo rom or should I just go ahead and try a wipe and then reflash cm7?
EDIT: Well something worked. Seems like I'm good to go, although I'm not really sure if anything changed in what I did to try and get cm7 running this time. Thanks for your help guys, and hopefully I won't run into any more problems here.
Im running hyperdrive rls12, and i dont have enough posts to put this in the appropriate section, however i need to know if i can avoid a full factory reset when flashing rls13, since it is the same rom and all. any help would be appreciated!

As with most roms, it's ALWAYS a good idea to do a factory reset & wipe caches before installing. In fact, the dev recommends doing it 3x to ensure proper installation and minimal problems. I always wipe everything before installing a new release, but that's just me. You can use apps like "Titanium Backup" to backup your apps before you wipe if you don't wanna re-download everything. Btw, rls13 is AMAZING!

i dont understand the difference from rls 12 in the changelog
Had a bit of trouble trying to do this last night, which resulted in a few hours lost sleep. I went formatting everything in CWM and realized after the fact, I also formatted the internal SD card. Luckily ADB worked in transferring the zip (learn something new every day).
Anyway, after all said and done, all my apps were still on the phone. This is after formatting and new ROM...
How can I truly start from scratch to make sure this new ROM is 100% fresh and free of any unnecessary apps from previous ROMs?
Also, what would be the best current radio and link to said radio?
TIA
EDIT: I had just realized the issue with Factory Reset/Wipe Data. This one I had forgot to mention as I could never use it as all options said no and the menu was not scrollable. Just decided to try and use the volume buttons and sure enough there was more to scoll to.
That said, would the following be a proper procedure to follow;
Wipe Data/Factory reset
Wipe Cache
Format: System, Data, Cache, Boot
Wipe: Dalvik then Fix Permissions
Install order: Rom first, Gapps second, Kernel last
Reboot
???

The method I follow is
1. Wipe Data/Factory Reset (this takes away all your downloaded apps?
2. Wipe system/cache/dalvik (this wipes everything else)
3. Flash ROM, Gapps, Kernel
The thing with android is, even if there are some files left over from the previous ROM, they'll get overwritten with the ones from my new ROM, taking them away regardless. The reason you wipe everything to make sure there aren't any files that won't get overwritten. So basically, wipe everything and flash, and you'll have a fresh new ROM also you don't need to fix permissions after you wipe everything because they'll be no permissions to fix! Lol

I don't know it offhand but its probably somewhere on the development forums. I just noticed I said "my new rom" in my original post, I meant "the new rom" just in case you were a little confused (probably not but that would've annoyed me if I didn't address it)

Newest radio I can find is from last year. Maybe that the newest. I know for certain signal and data is a million times better. However, I still have no 4g
And Im having an issue I ned to report about the ROM but XDA wont let me post... :crying:
