[Q] Why does Froyo require a data wipe?

I've been doing a lot of reading on this forum trying to find the best way to update to Froyo... seems like every ROM says it requires me to wipe my data. I'm curious why that is? The official OTA update can update to Froyo without wiping my data, so why can't any of the ROMS on this site do that?
I'm just looking to update to Froyo and then customize it how I prefer.
I am already rooted, removed all the sprint/htc bloatware i dont want, customized my boot up animation, and changed the sprint banner... Certainly I will have to re-do some of this after the upgrade, but I would prefer not to have to re setup all of my home screens, re-install apps, lose my app data, etc...
I understand that titanium backup can help make this a lot easier, but the question remains... if the official OTA update doesn't require a data wipe, why do these un-official updates?
Thanks,
~ Andy

1) This should be in the Q&A section.
2) I can't speak for the Evo, but my wife's Moment, when it was upgraded to the official 2.1, did not require a data wipe either.... Because the official update did the data wipe for you. Either way, she lost all her data. I suspect this is the same for the official froyo.
3) If you want things to go smoothly, always do a backup (nand, TB, etc) and always do a full wipe before flashing a new ROM. In some cases, this applies to themes and other upgrades. If you don't, it's on your hands if things go awry.

this is as i understand it. perhaps we'll get lucky and one of devs will come in and clarify this point for us.
quick answer:
when you call your IT guy with a problem what is the first question they ask? "when did you last reboot?" and then they have you reboot anyway. does that solve all problems? hell no. but if you knew how many times it did you'd understand why we do it.
... "did you wipe" seems to be that same kinda question.
what i think:
There are several partitions used by Android. and much like its big brothers the Linux OS's...the use of these partitions is well guided but not law. hence, some folks feel that dataX should be here and others feel it should be there.
there can also be configs that would conflict (things like HTC Sense are very deeply intertwined into the Android OS so an AOSP build would have conflict).
hence, to ensure that you (the end user of whichever ROM) have the best experience it's best to have you start with a clean slate. (it's plain old step one troubleshooting especially when dealing with so many non-techie folks)
once you have more familiarity you'll notice some folks don't wipe...but if they have issues, you'll often hear them go do a full wipe and report the issue was resolved. this is more true when upgrading...not so much when transitioning.
since the OTA was developed by the same organization that developed the existing OS...no wipe is needed.
the same can generally be said for those of us using CM6 and then flashing the nightly builds
the same can generally be said for those using Fresh ROMs and flashing updates provided by Flipz.
the same cannot be said for someone coming to CM6 from Fresh. much difference.
basically, the rule of thumb is "when in question...wipe". why? because if you don't and if you experience issues you may assume the ROM is bad or the dev is an id10T. then the non-techie may erroneously post such comments...causing a stampede. the board gets filled up with 'this rom sux' and 'plz help' for things that would have been a non-issue had a wipe been done.
I am already rooted, removed all the sprint/htc bloatware i dont want, customized my boot up animation, and changed the sprint banner... Certainly I will have to re-do some of this after the upgrade, but I would prefer not to have to re setup all of my home screens, re-install apps, lose my app data, etc...​you can try using Titanium. it worked well for me when moving between Sense based ROMs. it will save most of your settings. it had issues when i transitioned to CM6...so i had to reconfigure my email, IM, desktops, etc.
when you flash a new ROM, expect your custom boot animation to be reset to whatever the dev chose...but using PushBoot makes it very easy to fix.
if you use adw (mabye launcherpro) you can export your settings and then import them after the flash
you won't loose the pics/movies/mp3/etc by doing a sd:ext wipe. (just in case you were concerned)

HTC Desire - New to android modding - help needed

Hey everyone,
I'm really new to android modding, and don't know much about all this. I'm good at modding but never been on android before. I went through the stickies and full desire guide etc threads, but its really getting confusing for me.
I've come to know some things: (correct if wrong)
1) You have some custom ROMs which you can flash after rooting the phone.
2) Most ROMs have pretty much everything working, but some things don't work on some ROMs (like camera for some)
3) Rooting voids warranty.
Seeing the vast amount of ROMs in the development section, I'm confused which one to look for. Can anyone suggest me which would be the best (stable and everything working) ROM for me? I basically need APP2SD or APP2SD+ (NOT the froyo one because its useless, I'm talking about the custom one) and minor tweaks like changing the homescreen etc.
Which would be the best suited ROM for above description? Basically, what criteria decide which ROM to put on the phone?
@Moderators, sorry if its the same old story. I'm really confused and so HAD to make a thread.

Hi and welcome. A couple of points I can help you with:
There are loads of roms to choose from, I am using this rom atm:
http://forum.xda-developers.com/showthread.php?t=768703
Everything on this particular rom works fine and is very fast and stable. I generally find if roms have several revisions then are are generally very good. i.e. are having continuous support and developement.
As for rooting voiding warranty? Well this is no longer an issue as rooting can easily be reversed )
Hope this helps

You do indeed need to Root the device before flashing, the only ROM that don't have 'things working' is the Desire HD ROM. I am not sure if that has been fixed or not yet though. All the other AOSP and Sense based Desire ROMs have everything working just fine. Rooting will void your warranty but it's super easy to reverse so there is nothing to worry about.
The most popular ROMs by far seem to be the AOSP (Android Open Source Project) ROMs (Non-Sense ROMs), all of them will have APP2SD built into them, the Sense ROMs also have APP2SD built into them.
LeeDrOiD is by far the most popular Sense based ROM, RCMixHD is the Desire HD based ROM, which I think still doesn't have the camera working.
And by far the most popular Desire ROM overall is the ASOP Cyanogen based DeFrost.
To get the most out of APP2SD you will need to download ROM Manager and create an EXT3 partition on your SD card so the ROM will place all of the Froyo compatable apps into the partion and not your internal memory.

Being brand new to the desire, I've flashed every Rom available in the last 2 weeks.
Leedroid is a very good sense Rom. I prefer having a Rom with sense right now because this is my first HTC.
Right now I'm running the Aurax sense Rom, solely because it has its own setCPU built in.
The hd roms didn't impress me that much, not yet at least, with a little more time they will be awesome though.
The MIUI roms are also amazingly pretty, if you don't mind the iPhone feel. My only problem with it though, and I've been told this hardly happens, my battery life was pathetic.
At the end of the day though, apart from the hardware, it is android and all the available apps that make our phone so great.
All the custom roms do add a lot of speed to the phone though, you have to do a quadrant after you flash so that you can see how awesome the Rom makes your phone run. They also add additional functionality compared to the stock Rom.
Honestly, I can't see why anyone would keep any Android device stock when there are such amazing roms around. At the end of the day its all down to your own preferences and what functions you like. You'll love any Rom you flash.

Thanks for such amazing replies. Meanwhile, I've also been through many ROMs and their descriptions. The terminologies are kinda new for me, but I can understand many things now....
The only thing I care about right now is App2SD because I found FroYo's move to SD doesn't help much. Also second thing is that I'm not having MY desire yet, its my friend's device m gonna try out everything on! So I'd be taking some extra care!
One big relief is that rooting is reversible. That'd be cool.

It is honestly impossible to brick a desire. I bricked my MOTO backflip, there was no coming back from that. With the desire I flashed something that didn't work, but pressing volume down and power gets you right into the hbooot menu, from there just mount as usb and copy over a new Rom to flash.
The one thing you need to remember, when flashing new roms the first boot takes a while, never pull the battery thinking there's nothing happening, that will destroy your phone and there's no coming back from that.
Before every Rom you flash make sure to do a factory reset in the recovery menu, that ensures that the new Rom will work to its full capability and minimizes the chances of experiencing problems.

You can brick your device flashing Radios, but you can always send it back to HTC, pay them an extortionate amount and they will revive it for you. But overall, the chances are slim to none in my experience.
Just make sure, after rooting, you make a Nandroid backup of the OS. Then you can do whatever you like to the phone and it will be reversable.
I keep a Nandroid of my DeFrost ROM, and one of my PaysROM, and I have one of my MoDaCo R8, you can switch between them just using Recovery, as the mood takes you, absolutely everything will be exactly as it was everytime you load the backup back onto the phone, I just wipe the cache, Dalvik Cache, factory reset the ROM then reinstall whichever ROM I want to use (DeFrost, PaysROM etc etc) from the SD card and then backup from the Nandroid.

Depending on the age of your desire, you shouldn't need to flash a radio though. I've never needed to flash a radio, but that's because my desire came with the latest radio, thankfully it still has the amoled screen.
If you do need to replace the radio and somehow brick it, if its still under warranty HTC will replace it for you because there is no way that they can prove you bricked the device.

Wow that means you install a ROM, make settings you want, put in your data (phonebook etc) and then take a full backup. Switching between them is as easy as restoring a backup!
Is that right?
Initially, I'd be trying out ROMs, and would stick to the one which suits me best. I just can't wait before my desire arrives this monthend!!

It saves everything, app data, messages, settings, the lot. Although when switching ROMs I still factory reset, wipe the caches and reinstall the ROM I want to use before loading the backup of that specific ROM. I am not sure things will go so smoothly if you just reload the backups without factory resetting and reinstalling the ROM first, but it won't hurt to try.

I have not been able to fully understand all this rooting and flashing etc...O_O so i installed ROM manager, which now some peeps are sayin dont use if you dont know what you are doing WELL HI, THAT WOULD BE ME so for all the experts, gods and godesses of rooting (EVO) flashing, please please please help me from start to absoulute finish...i need to know what am i downloading, running, saving and to where- that was a huge issue too i couldnt find the files after i downloaded them LOL if i am successful...I will post the greatest YOUTUBE, forum, blog about this..i am so lost right now
b4 i forget a couple updates of info everytime i tried to flash or do any type of recent updates i get the usb connection 170 error or maybe 171 cant remember now....ummm...i rooted originally with unrevoked so unrooting i wouldnt have a clue...and yes i have searched allll possible threads for help but i only get 50/50 and then still get messed up..thanks
thanks again and happy rooting

While I am not going to hold your hand as there is plenty of information on these forums and the internet, I will steer you in the right direction. Since you are rooted, all you really need to do is download the rooted version of the latest stock rom. There are a few in the development section. The version is 4.22. After downloading you will flash this rom in recovery. Make sure you do a nandroid backup before flashing the update.
DO NOT unroot just to install the update. You will lose the ability to root hour phone for the foreseeable future.
Good luck

ok thanks i will try it now...stay tuned

Ur not going to see much difference. The update dissapointed lots of people expecting a new look. Install a couple of custom roms if u want to have some fun. I am using the MikG v1.03 Rom with new sense incorperated and its waaaay better than the stock update we just got.

Pleat try to see this as advice and not being an ass.
Rooting your phone is really for being able to dig in to your phone and get all you want out of it and be able to customize more than the average evo.
What were your initial intentions for rooting? I get the draw to have free wifi tether but, that just happens to be one perk of it. Of course, there are the options of kernels and cpu clocking.
But, really the developers are attempting to bring the newest and most useful and functional features to the roms opening the full potential of your phone.
Aside from that, if you are unclear and confused about the process of flashing, you should really hold off and do some more research.
Go to the wiki page and read up! i spent about a month reading everything I could find on rooting, flashing, kernels, radios, prls, threads on roms and their issues and up sides. I knew what I was doing and what rom and features I was going to use.
Honestly, youtube will also be your friend. A few devs also post videos people have made about their roms including how to flash them. You should also read up on the results of mistakes made during flashing and how to fix them.
Get to know your phone and submit it to do your will!
Good luck!

Your apps were gone because you wiped data. Try Titanium Backup - there's a free version in the market that allows you to backup and restore, get the Pro key to avoid agreeing to the permissions/install of each individual app. The Pro version also allows for a larger number of backups per app, where the free version limits to one and when you make another backup it overwrites the first one. You can also freeze apps with the full version, but if you enable "Chuck Norris Mode" in settings the free version will allow you to uninstall system apps. There are other perks to the Pro Key, but I digress...
If you backup your apps & data, you can restore them on the new one. Whenever you flash a new rom, always wipe data, cache and dalvik (dalvik cache is under advanced in Clockwork). If you're simply updating the rom (ie to a newer version by the same dev, like Cyanogenmod nightlies) you can just wipe cache and dalvik unless otherwise stated in the rom. Whenever you flash anything other than a rom - kernels, themes, mods, radios, etc - do not wipe data.
If you don't know which rom to use, as long as you have a nandroid backup you can always go back to your setup that you like... so flash away. If you want to stick with something closer to what you're used to, try Myn's Warm TwoPointTwo... it's still FroYo. If you want Gingerbread/Sense, I've heard great things about MikG. I would avoid any rom that needs you to partition your SD card until you get your feet wet & know what you're doing.
Oh, and if you decide to flash the new radio update, don't pull the battery when you see the screen you've never seen before - you'll brick your phone. Just wait it out, and it'll take you back to recovery where you can then reboot normally.
(from... Evo/MIUI/Tapatalk)

Definitely look at Mik, and learn all you can about partitioning your card for APS2SD, you'll want that for the bigger ROMS, about flashing radios, very important to do that correctly, about theming, and so many other things that being rooted opens up for you.

Mik is great for sure, also kings roms. If you want something that is still htc sense there are many great developers and right now is the time because they are able to merge ports with the ota for the max performance for our phone while running gingerbread and having nifty new 3.0 sense features.
And maybe someday you will venture to the aosp world some day...

[Q] New user with ILWT rom questions

Hey guys, I just rooted my DZ and now I’m ready to switch to a custom rom (I’m currently on stock 2.2 sense rom). After doing some reading I think I want ILWT. As I have never done this before I would feel more comfortable knowing what I’m doing rather that regretting something latter. So here goes
First of all, if I first wipe data/cache with superwipeG2 and do a nandroid backup, will the backed up rom work after restore? (I would like to back up the stock rom, without the apps I installed).
Second, I know I need to wipe everything with superwipeG2 before going to ILWT, but should I also do a factory reset?
The most important thing is will ILWT run ok without eng-hboot, as I did not flash it during rooting (I didn’t feel comfortable with that)? From what I understand ILWT will automatically flash a new kernel with all kinds of goodies? I don’t need a super extra fast rom, I just want it to be reasonably stable so I’m guessing I’ll go with ILWT kernel. Also, how wide spread are the GPS issues, does everyone suffer from it or it just happens to some people?
So what do you think about my choice and is there anything else I should know before I proceed? All your answers would be much appreciated, thanks

ILWT is the best and stable ROM if you ask me. I just recently left it to play with the ICS ROMs floating around. I had no issues with the GPS while I ran ILWT. I have GPS issues now with the ICS ROMs, but I expected that. I would flash the hboot if I were you. While it seems intimidating, it actually isn't and very easy to do as long as you follow all the instructions on the rooting guide.
I didn't do a factory reset, but I did do a superwipe and wiped cache/data/davlik just to be safe.
As far as the OEM ROM goes, http://forum.xda-developers.com/showthread.php?t=1442988 is a GREAT resource to go back to OEM specs and has a nifty directory with all the official OEM ROMs.
Hope this helps a bit. I'm also a noob at this ROM thing and have learned a ton while reading all the info on this forum.

ILWT is the best in stability and speed, and it is a super extra fast rom
i think superwipeG2+ will wipe your /system partition too, which contains the rom, so if you super wipe, then backup, you won't be backing up anything... maybe
what i'll doo is just wipe data/factory reset and then flash ILWT, and then reboot... that's it

Thanks for the advice guys. I’ll flash the rom first thing in the morning

———————————————
i didn't mean to flame you, nor to mock you in any kind of way

If you want a nandroid of your current rom without the apps and such just do a factory reset before you do the nandroid. Of course this may be silly for you would have the same affect as just flashing the rom later. Get an engineering hboot, well worth it. Then do a superwipe (I also wipe everythin else cause I'm a little ocd, even fastboot -w) and then flash away. Remeber when you have a rom the way you like it, even a week or more for now, do a backup and then if you screw up in the future you'll be saved
Sent from my HTC Vision using xda premium

ILWT is about as fast and stable as they come. If you are used to Sense, and like things such as the Sense widgets and camera, you may miss them. Otherwise, ILWT is one of the best out there, and you will not be disappointed.
Anyway, if you make a nandroid, you can always go back if you don't like ILWT (or any other ROM for that matter). Nandroid is pretty awesome, as it will restore the complete image of the system when you backed up, with apps and data intact, just as you left it before flashing the new ROM.
I'd say the GPS issue only happens to a small minority of people on ILWT and other versions of CM7. I didn't have the issue with the GPS not connecting at all, but apparently some people do. And its an issue that has popped up for some people from time to time, on various CM7 builds in the past. I did have an issue with GPS fix being slower than on stock Sense (maybe 2 minutes versus 5-10 seconds), and the following fix did the trick, and got me consistent GPS fix in seconds:
http://forum.xda-developers.com/showthread.php?t=1472870
At least one user used the same to fix his issue of no GPS fix, after I suggested it:
http://forum.xda-developers.com/showthread.php?t=1616627

Again, thank you all for your help
My DZ just got some ILWT love and its running perfectly ))

Does anyone remember Pyromod Mecha Micro ROM? I am still using that rom, and it was the fastest and saved a ton of battery life.
Is this ILWT rom better then pyromod mecha micro?

[Q] Running gedeROM 1.55 looking to change ROM's

As the title says, I am running gedeROM 1.55 for the past year, since I experimented with a couple ROM's and settled on this one. For the most part its been a decent daily driver but have found it a little 'sluggish' lately and it annoys me. The lack of deep sleep keeps me always scrambling to keep it charged and ready to go so I don't find it dead when I want to use it.
Of course in the process I am using an older version of FFF and TWRP, so I know an update of them would be necessary.
A couple questions, looking for opinions:
1. Is it possible to just use KFU and update FFF and TWRP without disturbing everything else? I'd like to get them up to date.
2. After reading for 2 hours or more I am unclear on the limitations of 10.1 JB and wonder if I should be changing to JB at all?
3. Are the 10.1 ROM's a better option than I am running for speed and reliability? If so, any shining star amongst them?
I know asking for opinions will bore most people to death reading this, but I need some guidance from those that have been active and keeping up with ROM dev on this unit while I left mine alone and got behind.
Thanks in advance.

This might help you:
1. Look on the first post of this thread. Theres a flashable zip for FFF1.4 (Just flash in TWRP)
2. Here is Ichigo's flashable zip for TWRP 2.5.0 (Just flash in TWRP) https://www.dropbox.com/s/b4idirzkmgvnm07/TWRP-Blaze-2.5.0.0.zip
Those will not disturb anything else.
And try This ROM first and see if you like 4.2.2. This is the OFFICIAL cyanogenmod 10.1. To me its by far the best in terms of stability and speed. Make sure you wipe everything BUT /sdcard in TWRP before you flash!

Moving to a recent JB ROM will be a good move compared to gede because not only will you have better battery life but you'll have almost another year of improvements made to the Kindle since then.

Thanks for the info.... I'm gonna give this a shot I think. Not much to lose, nothing mission-critical on my tablet anyway
I'll post back once it's done!
Thanks again.

It seems to have gone well, thanks for all the info. Updated FFF, TWRP, and now on CM 10.1 ... I did the 5/20 nightly, wasn't sure which one to do -- seems pretty bug free at this point.
