Definitely. I see no bugs as of yet, and the browser speed is, wow. Flash is great, and so is official tethering. There are no cons to having froyo.
[Nexus One General] 3bs:
Played with it for a while but went back to Enom 1.9.2. I need my trackball wake and black status bar.
[Nexus One General] D200P13:
at this moment i am keeping it. apps 2 sd default on froyo and root is all i need!
[Nexus One General] Rusty!:
As a stock user, I am unable to ditch it, however I have no need too anyway, it runs great for me.

Bring on the final build.
[Nexus One General] Buck Shot:
i see the smiley face now,lol but i know how it is when i was a noob and looking for help....
[Nexus One General] attn1:
You can use the new implementation of apps2sd even if the app isn't written to use it automatically.

open terminal

su

pm setInstallLocation 2

Then you can go to app manager and move your market applications over. Just don't move widgets and things that load before the SD card mounts.
[Nexus One General] hjaltih:
I am really loving it but I would like root and maybe some tiny tweeks.

Really not regretting switching away from the drsire atleast.
[Nexus One General] galaxys:
I like much better than 2.1 and so far it runs great for me!
[Nexus One General] derekdlc:
I enjoy froyo, I have been using it for a couple of days now and so far everything is great. It is fast and i enjoy the new UI tweaks. I have 4 nandroids: 1 Eclair 2.1 stock, 2 Cyanogenmod 5.0.6, and 1 Froyo. I find myself missing the little things like music changer with Volume up botton when in standby mode, or rounded notification bar, or trackball notifications, wake phone with trackball that cyanogenmod provides. So i use Froyo to show off to my peers and I will patiently wait for CM 6.0 Froyo base to be released.
[Nexus One General] Sk0t24:
Keeping it until we see a stable CM6.
[Nexus One General] derekdlc:
I agree, cant wait to see CM 6.0
[Nexus One General] ralexand:
+1

There are too many things I prefer in CM5.* that Froyo doesn't have, like trackball wake (huge dealbreaker). Not to mention that a lot of apps aren't updated or froyo yet.

Don't get me wrong, froyo is amazing, but I am more than content with waiting for CM6 (or more likely, CM6.0.1 ;) )
[Nexus One General] jz9833:
I'm keeping Froyo until Enomther releases his version. Froyo has even better battery life than Enomther had which is amazing, but I miss WMA/WMV playback more than anything else.
[Nexus One General] codesplice:
I'll be keeping FroYo and waiting (with the others) for Cyanogen to work his magic and turn out a solid FroYo+sprinkles release.

In the meantime, it does everything that I need it to, and I'm blown away by the speed.
[Nexus One Q&A, Help & Troubleshooting] z0phi3l:
I tried and failed to get 2.2 going on my phone and phone now will not boot

Want to go back to 2.1, I'm not rooted, don't think I can root in the condition it is in

Once I have the 2.1 ROM downloaded what are the steps needed to flash it? Are the steps the same as for getting 2.2 flashed or should I try another way?

Getting an image or file to the SD card is not a problem, I have an adapter
[Nexus One Q&A, Help & Troubleshooting] shep211:
How-to go back to stock rom if needed.

If it was me I would root the phone then install Recovery RA-nexus-v1.7.0. Then flash 2.2 rom that can be flashed via Recovery.
[Nexus One Q&A, Help & Troubleshooting] hondasr:
You can go back to 2.1 just follow this guide and you dont need root.
[Nexus One Q&A, Help & Troubleshooting] z0phi3l:
Can't follow the guide, phone is stuck in the static N1 logo

None of the commands will work, I need a way to do it with the SD card and recovery
[HD2 General] wayandrs:
So I finally got rid of my iPhone 3G (jailbroken on T-Mobile), and got an HD2 instead. I've always liked Windows Mobile phones (and had most iterations), and since now there is finally some capacitative goodness on WM, I jumped on the opportunity.

And I'm regretting it already.

I'm hoping that somebody here has some suggestion that my two days of thread searching, and experimenting didn't cover.

The problem is, yay, .... the damn battery.

I left it on the charger from totally empty to completely full at 2AM. At 8AM, it was down to 85%. Ten minutes of reading e-mails, 74%. The thing is really not usable in this state.

Here are all the things I checked already:

It runs the latest T-Mobile ROM and radio (the one that just came out a few days ago).

Latest version of .NET (3.5.9).

No push e-mail, e-mail checking once per hour, weather checking once per hour.

Strong 3G coverage area, still tried out WMLongLife anyway (with no difference).

Did several cycles of full discharge, recharge.

Always check task manager, not leaving programs running.

Nothing else is set to go online - Live is disabled.

Screen brightness is set at 30%.

All charges done via wall charger.

I read every post I could find, especially fun the ones where people get 4 days of standby, and 6+ hours of heavy use. Short of loading the ARTEMIS ROM, I exhausted all options I could find. And really, it seems like people get decent performance from the stock ROM, so I'd like to stick with that for the moment.

What am I missing?

So frustrating. I can see how this sort of thing would make the average "just user" go run for the Android or Apple hills. No wonder we get stuck with restrictive babysitting technology, when others can't get their **** together. Spend $450 on a phone that can't make it through a half day of reasonable use? Argh!!

Any suggestions would be greatly appreciated.
[HD2 General] bigbadmoshe:
same here

i have all the same problems my batt just sucks i figure i have to just by a new one
[HD2 General] fracmo2000:
hey man, i was like you at first too. all my mates had iphones (i dislike apple in general) i didnt want one. At the time o2 (uk) didnt stock android phones and i had a sony x1 previously. So, i got the hd2 and...like you said was disapointed.

Changed the rom to a custom one here at xda (hdowners btw) which lasts 1.5 days (heavy usage)...never seems to get 2 full days when i use it alot.

installed a few different browsers (opera 9.7 and 10)

installed morphgear (with some amazing landscape skins)

fpsece (i found time crisis to be the only actual playable game)

coreplayer

and found it a awesome phone...changed my views on it. Try some custom roms and see what you think...usually you will go mad installing themes, skins, apps...just go wild and keep the ones you really like/work in a seperate folder. Then reflash and install the best only...thats how i done it and i now love this phone :D

good luck, im sure the rest of the forum will give you some advice.
[HD2 General] jrrigney:
wayandrs: The main thing that will help is by upgrading the ROM even if it is to stock 1.66 (the latest UK one available) then you notice a large difference and even more so with some of the cooked ones. Other things to note are the WiFi, make sure it doesn't be left on (and only turn it on if you need it) it proper drains the battery. Without knowing your habbits with your phone it is very hard to come up with decent suggestions that hasn't already been posted elsewhere.

I can safely say I get 2-3 days use out of my device but then I don't use it all that much (anymore), don't forget as it is a new toy for you, you will keep playing with it seeing what it can do, this will soon die down (as it always does) then it will be better.
[HD2 General] DN41:
there must be something wrong with your device or battery.

mine lasts for about 3-4 days while middle use. i think for such a powerful and huge device, this is more than respectable.

heavy use...mh...i would say it lasts minimal 2 days, sometimes more.

did you write a complain to t-mobile?

DN41
[HD2 General] webjunky:
The battery will improve after a week or so .

Note : charging your battery the first time for only 6hours isn't much , the first time that i charged my battery i left it charging for 24 hours.

Updating to the latest ROM and Radio helps .
[HD2 General] ribcage:
I have two suggestions:

1) Take your phone back to where you bought it and let them deal with it. I get at least a full day with heavy use which is to be expected from a high end device with a 4.3 inch screen. I spent a few dollars on a car charger and an extra wall charger for work, sorted.

2) If you want help on these forums leave out the useless complaining about what a rotten device you have. I think I speak for many contributors of this forum when I say that these kind of posts are getting old and wearisome. You will be more likely to get polite replies with inteligent suggestions if you simply state the problem without moaning about the horrible mistake you made in being seduced into buying an HD2. I have purchased phones that I simply did not care for. I returned them.
[HD2 General] Uvaavu:
First step: Flash a decent ROM with most of the performance/battery tricks in there already. Many of these ROMs are constructed from the best (often most battery efficient) parts of multiple ROMS.

Touch-X, Energy, Artemis, CleanEx, etc. All are excellent (though I favour Touch-X myself for a great utility/preformance/battery balance).

Second step: Flash a good Radio that works well in your area but also works well with the ROM/has decent battery life. You'll need to research this for your chosen ROM.

I use the Korean radio in UK. Good quality/signal/battery life.

Run it for a few days, charging to full and emptying the battery before recharging to full again. Do this for 3/4 days at least.

Those changes alone got me upto 2.5 days standby and 4 hours usage (thats movie playing for 4 hours with 100% backlight in a hotel room). Good for a smartphone and longer than my friends IPhones.

Other small programs like WMLongLife, adjusting down the backlight automatically, added another .5 days to standby (though not much to active use life).
[HD2 General] Farsquidge:
Yes, sorry I fell back on the usual retoric.

I do wonder though if when someone buys a new 'Toy' that they dont hammer it to start with for the 'joy' and never think of the consequences.

I like you, no matter which phone I own, being a businessman and needing maximum performance have a charger at my bedside (the phone is my alarm) and also connect it to the car charger when driving.

I wonder if many of the people that move up from a basic Nokia phone (or similar that can last a week) realise what is involved in powering all the functions they require?

Please don't quote iPhone as it dunt do half! :rolleyes:
[HD2 General] tarekkkkk:
try elegencia rom v 8.5 and reply back ;)
[HD2 General] Sheikmans:
I use the stock rom 1.66 from the beginning and check my mail automatically every 30 minutes. Now and then I check some websites and download cabs and use HSDPA/3G and WIFI if available. My battery is 100% in the morning and 70 percent in the evening. Not bad at all. The first 12 times I fully charched the battery during the night.

I use Bandswitch, which automatically disables my connection within 30 seconds. This is the most important and useful tip! You don't need a custom ROM to solve the battery drain issue.
[HD2 General] jrrigney:
+1 - Lovely ROM
[HD2 General] hoss_n2:
it looks like you have not a windows phone before
[HD2 General] wayandrs:
Thanks.

Thanks for the ROM suggestions. I'll try a few more days of deep cycling the battery to see if that helps - if not, I guess I'll try a custom ROM.

And yea, to those 'get a life' and 'don't complain about Windows phones' posts, whatever. I've owned Windows Mobile phones since they first came out, and it's just frustrating that the out-of-the box usability hasn't gotten any better to this day. Looks at the cool people that actually manage some constructive feedback - they are who make XDA forums great. Thanks guys!
[HD2 General] karlpj:
A new 1200 battery is 15 pounds (the official from HTC) as a backup. I personaly have bought the extended battery 2400 and it is great. The default battery doesn't last the full day for me because I use it constinuosly as mp3 player , brownsing and video player. I mean, you have options.
[HD2 General] wayandrs:
ROM

I'll be trying the Elegancia ROM.

That is, once I find a ROM with 2.8 SPL that works on my 1024 version of the H2, to reflash mine so I can get HSPL to work to flash.

I've always really liked Windows Mobile for its flexibility and massive base of developers ... on the flip side, I've been screwing around with this thing for several days now, trying to get a phone that can last through a day. Ahhh, the bittersweet experience that is WM. :-)
[HD2 General] M3PH:
I get at most 2 days combined cycle out of my stanard battery and i've had my phone for about 10 days. It came with the stock 1.66 rom but i've run through the tips and tweaks threads so the phone ui is faster and a bit more usable. One of those is a replacement task manager that disables smart minimize in favour of actually closing programs. I've also set the weather software to update every 3 hours because tbh you don't need it to be any more often than that. I do use the wifi alot but i do turn it off when i'm not using the phone. i have also noticed with my phone is if the wifi is connected to an access point for more than 5 minutes it will automatically disable the 3G connection and turn it back on when the wifi is disabled.

for the first couple of days i was completely discharging the battery and then charging it for about 12 hours. this seems to have been the most beneficial. i also will not put it on charge unless it really needs it.
[HD2 General] leobox1:
hi, from experience, 3G medium usuage.. 4/5 a day.

If you disconect the 3G connection when not using, it will help.

And of course if you go on GSM instead, one day is not difficult..

battery killer :

1) constant 3G activity

2) Watching video. Worst, video on 3G !

3) games, especially the 3Ds ones or high on processing like the Tower simulation game.

4) bright screen

5) bluetooth
[HD2 General] enyaj:
From my experience, from a fresh flash, my battery improves as I get to use it longer and longer.
[HD2 General] cma1032:
take a look at your data sync like weather and stock and also check the social networking sync.
[HD2 General] pdahunter:
Don't forget to load your device directly over AC-Connection, not over USB. Plugged in AC a full loading should be finished in 2-3h. Over USB it's very difficult to load the battery at all.

Moreover it's highly recommended to take a second battery and a docking station with battery charging capability (check for simultaneous connection to USB and AC).
[XPERIA X10 General] DaHiA:
Following my eagerness to the young android OS,

I'm moving from Xperia X1 to my new X10 and i'm trying to move all data including contacts, calender, notes, etc..

I got a problem with MS outlook so i went to Sonyericsson suggestion about using Sonyericsson Sync

I'd appreciate a simple guiding steps on how to use SE sync service so i can start enjoying my new android masterpiece

Thank you a bunch
[Nexus One General] creepinshadow:
You might think i'm crazy, but i'm dependent on CoPilot Live for Android, a navigation app, and it doesn't work in 2.2.

So is there a way to go down to 2.1 again? (preferrably without rooting)

would it be possible to just take a "update.zip" from 2.1 and follow the same steps like i recovered to 2.2?

any input is appreciated :)
[Nexus One General] Rusty!:
You can only go backwards if you've unlocked the bootloader.
[Nexus One General] Mi|enko:
Shouldn't he be able to use the signed release image in fastboot?
[Nexus One General] Rusty!:
Nope, it wont let you go backwards.
[Nexus One General] Scream1337s:
Are you sure that it doesn't work? What if you connect your phone and download the original rom and use Fastboot to flash this rom would you need an unlocked bootloader?

Greez
[Nexus One General] Rusty!:
Need to be unlocked.
[Nexus One General] ScaredyCat:
AFAIK using a PASSIMG should do the trick, you'll have to go through the upgrade process too to get to 2.1.

SC
[Nexus One General] Rusty!:
You cannot go backwards with a stock bootloader, how many times do I have to say it?
[Nexus One General] nexus5894:
Does CoPilot not work at all, or is it just not available on the Market? If it's not available, you can find a phone that it works on and is rooted and do an "adb pull" of the application file, then place the file on your phone's SD card and install with a task manager.
[Nexus One General] Mi|enko:
See. That's what I was thinking. I thought the signed image would just flash all contents, regardless of the version. . .that's how we gained root on G1s (flashed down to rc29). Pretty sure it related the radio too.
[Nexus One General] pjcforpres:
We don't have an NBH file like the RC29 file was. Until you unlock the bootloader, you can only flash the phone using the stock recovery, and it has to be a signed update zip, and it won't let you go backwards.
[Nexus One General] dsixda:
I have the same concern too with 2.2 and CoPilot. The CoPilot guys said they are currently working on a fix, so I would just wait a bit longer.

If you need GPS right away, then in the meantime just use the Google Maps Navigation or Brut.all's latest version of the hack that works for non-US and non-UK countries.. works fine in Canada for me.
[Nexus One General] itslinx:
So there's no way to go back to 2.1 at all? Cause that's definitely something I want to do. My battery life (since having 2.2) is HORRENDOUS. Absolutely terrible. I can't deal with it right now.
[Nexus One General] Rusty!:
You have to unlock the bootloader to go back.
[Nexus One General] itslinx:
Any chance you can tell me how to do that? Does that involve rooting?
[Nexus One General] Rusty!:
No, but it is a prerequisite of rooting.

There's a bunch of guides on here though, can explain it miles better than I could.
[Nexus One General] spazoid:
Do a search there is a tut.

AND I AM BACKING HIM UP...FOR THE LAST TIME YOU HAVE TO UNLOCK THE BOOTLOADER TO REVERT BACK TO 2.1
[Nexus One General] itslinx:
Thanks to both of you.
[Nexus One General] lbcoder:
For everyone's information, the latest version of copilot also does not work with CM5.0.7 on Dream, however an older version, 8.0.0.606 *does work*. In case the same glitch is hitting them both, you might consider trying the older version with 2.2.

Also, please post the "logcat" for when it crashes.
[Nexus One General] lbcoder:
Is there truly NOBODY interested in trying this?
[Nexus One General] maedox:
It was getting heated. They all went outside to fight. :p
[Nexus One General] ihearttreo:
You can downgrade. Check here : http://xdaforums.com/showthread.php?t=688562

I followed the complete instructions and i'm not rooted and I was able to revert back to 2.1.

Here's from the thread.

(1) go to androidtechnical.info

(2) click on "ANDROID ROM LIBRARY"

(3) type "Google OEM" into the search boy (of course without the "")

(4) click on "Search"

(5) click onto the "Google OEM" link that says "Nexus One Shipping ROM (Original)" in the "Version" column

(6) at the bottom you will find the download link

(7) happy downloading

(1) Do a Factory Reset via Android OS

(2) Reboot into Fastboot, go into Bootloader and click "Cleare Storage"

(3) Reboot your phone, plug it into USB and make Windows access it via USB

(4) delete all files on the SD-Card, format it, and then copy the PASSIMG.zip onto your SD-Card

(5) Shut down your phone and boot it into fastboot again and go into bootloader again. Now the phone will regonize and load your PASSIMG.zip and ask you if you want to update.

Everything that follows this instructions should be self-explaining (press yes to update etc.).
[Nexus One General] Blueman101:
Can anyone confirm ihearttreo's previous response. I have read similar instructions on other forums so can anyone confirm?
[Nexus One General] pjcforpres:
I thought the bootloader checked for a .nbh file, not a .zip file, and that we didn't have the signed PASSIMG.nbh file for our phones.
[Nexus One General] Blueman101:
also doesnt that mean that you had to unlock the boatloader thus voiding warranty?
[Nexus One General] Rusty!:
Well a few people are confirming it. Google must have made some sort of allowance in FRF50 due to it being pre-release as it's never been possible to go backwards before. I tried to go from ERE36B to ERE27 and it was having none of it.
[Nexus One General] ihearttreo:
Well, it worked for me. My Nexus is completely stock no modifications what so ever. If I knew this was such a big deal, I would have made a video.
[Nexus One General] Blueman101:
but in order to go to the bootloader you have to unlock it right? thus voiding warranty right?
[Nexus One General] ihearttreo:
No, you do not unlocking of the bootloader.
[Nexus One General] Blueman101:
oh, so just booting into fastboot then to bootloader is not concidered unlocking the bootloader?
[Nexus One General] Rusty!:
No it's not, unlocking the bootload is done via the command prompt.
[Nexus One General] svet-am:
I can confirm that the steps in the first post worked for me to restore from FroYo back to Eclair.

Those of us familiar with this process automatically assume that the ZIP needs to be named "update.zip" and skip over the first couple of steps in the post.

Follow the post _exactly_ (including naming the update PASSIMG.zip) and it works like a charm.
[Nexus One General] rjhay22:
I know many have posted saying there isn't a way to revert back to Eclair on an unrooted device... but here's a link that says otherwise, if you want to try it out.

I just did the entire process in less than 10 minutes and reverted my Nexus One (2.2 FroYo Leaked on Day 1) back to stock 2.1.

It sucks that I have to wait for the phone to receive the OTA for FroYo, but at least now it'll be legitimate.
[Nexus One General] rjhay22:
Good :-) guess it does work.
[Nexus One General] RogerPodacter:
I just went from froyo back to cyanogen. Took about 10 min and was easy. Just placed the cyanogen zip and Google apps zip and old radio zip on my memory card. Boot into recovery, wipe, then flash from zip. Then restored a nand backup and up and running.
[Nexus One General] deprecate:
they were talking about doing so without unlocking the bootloader.
[Nexus One General] MadFlava:
Doesnt work for me. Gives me "Main Version Is Older" and fails.
[Nexus One General] creepinshadow:
worked flawlessy for me :), without unlocking the bootloader i went from manual 2.2 to 2.1, and then 2.1update1
[Nexus One General] androidaddict23:
it does not work because the market is not optimize for 2.2 because its not a release update
[Nexus One General] creepinshadow:
yeah, it gives an error message when starting

[Nexus One General] techlogik:
You just need the latest Eclair Radio. Your favorite Rom and Kernel.

1) Wipe

2) Flash Eclair latest Radio

3) Flash favorite Rom

4) Flash favorite Kernel

Which you will probably end up doing because there are so many problems with that test release.

I'm going to wait for a Desire Sense 2.2 custom Rom, probably later this year.
