[Windows Phone 7 General] Phone Titan:
The 8GB storage is a little disappointing compared to what some of the other phones are offering but if you don't really put much music / videos on your phone then it should last.
[Windows Phone 7 General] agp64:
:eek:

The highlights of WP7 is Zune [music,videos,games] If there is not enough storage available then why should I wast my money on this phone?

If I still have to have a separate media player to play music and videos I will just stick to a cheep Nokia and separate media player.

I was hopping this would be the ideal all in one device for me but the small memory capacity on a few of these phones is holding me back. I will not be parting with my money unless I can get 16 GB minimum.
[Windows Phone 7 General] 001mic:
@agp64: So buy the LG then... there are options right now with 16GB
[Windows Phone 7 General] RustyGrom:
Yes, they do get resized (don't remember to what off the top of my head). The only way to get the full version is to email it or sync it with Zune.
[Windows Phone 7 General] phoenixwithin:
You realize you can stream anything through Zune wherever you have service, thus not requiring you to use ANY space at all on your phone for music? Granted that could get pricey depending on your data plan...
[Windows Phone 7 General] freddx:
wait for better windows 7 phones. Later windows phones are much better, faster and with more storage. The now upcoming devices are too young to be the perfect phones. Even win mobile 6.5.x has more functions(and its easy to get much storage) than a windows phone 7 device.
[Windows Phone 7 General] davidebanks:
if we all wait better windows phones then there will be NO WP7 improvements! they at least need a reason to continue with wp7 ( it has huge potential) but if we dont support them then its game over already! i bought my phone knowing full well that features like copy and paste will be added and hardware will eventually get better if people buy now!
[Windows Phone 7 General] StevieBallz:
The reserved size you can set in Zune is so that a user can say: ok, I want 10 % of my memory free at all times so I don't accidently fill my storage space with music and when I'm out I find out that I can't take a picture or record a video as there is nowhere left to put it.

Edit: Had no problems with the 8GB storage on the Touch HD but on the Omnia it's really about to get cramped - especially as the games take up a lot of space.

[myTouch 4G Android Development] travisjames:
This guide will show you how to downgrade your MyTouch 4G from the recently released OTA to the stock build.

This WILL wipe your device! I am not responsible for any damages!

NOTICE: A lot of people have reported -including me- that using this method to downgrade your firmware will cause your MT4G to not receive the OTA that was released right after the phone was.

What You Need:

Hex Editor such as Bliss

Temp-rooted MyTouch 4G

ADB

This ROM - Stock ROM

1. Download the ROM and rename to PD15IMG.zip

2. Place PD15IMG.zip on the root of your SD card

3. Un-mount SD Card

4. adb shell

5. su

6. Now, run this command:

dd if=/dev/block/mmcblk0p17 of=/sdcard/misc.img

7. Mount your SD card

8. Copy misc.img from your SD card to your computer

9. Now open the misc.img on your computer in your Hex Editor

10. You should see something like:

1.17.531.2

11. Change that to:

1.14.531.1

12. Now save as miscnew.img

13. Unmount your SD Card now

14. Now in adb shell run this command:

dd if=/sdcard/miscnew.img of=/dev/block/mmcblk0p17

15. Power off your device

16. Now boot into Hboot by holding down "volume down + power"

17. The phone will scan for PD15IMG.zip and will ask you to flash it

18. Select Yes [DUH!]

You should now be downgraded from the 2.2.1 OTA back to stock 2.2!

I would like to note that this downgrades the HBoot/Bootloader, radio, system, data, amongst other partitions of your phone.

Also, since I downgraded, I have not received any notifications for the OTA as of 11/8/10.

This guide is a derivative of Apache14's OTA and Radio downgrade guide for the T-Mobile G2: Here
[myTouch 4G Android Development] cdw9800:
Cool

What are the advantages of downgrading?
[myTouch 4G Android Development] travisjames:
At the moment, probably nothing.

If an exploit for root were ever found in the original stock build, but was patched in the OTA, then this would be useful.
[myTouch 4G Android Development] Mr Bill Florida:
I am getting..

cannot open for write: Read-only file system

That is after following everything to the letter....
[myTouch 4G Android Development] Mr Bill Florida:
NM, sdcard has to be mounted....
[myTouch 4G Android Development] travisjames:
At which part does the sdcard have to be mounted?

During this part?:

dd if=/dev/block/mmcblk0p17 of=/sdcard/misc.img

I guess that would make sense, but I didn't have to have my SD Card mounted during this part which makes me wonder.
[myTouch 4G Android Development] Mr Bill Florida:
step 3 ignore

step 13 ignore
[myTouch 4G Android Development] Mr Bill Florida:
When I received my update to 2.2.1 it was over 5 hours after I activated the phone. Might take as long or longer depending on the network.
[myTouch 4G Android Development] Phateless:
Nice work!

This will probably be the first step to rooting when the devs finally figure it out. :thumbup:
[myTouch 4G Android Development] cdw9800:
Oh ok I figured that good with ill keep it in mind
[myTouch 4G Android Development] HamNCheese:
So basically HTC is not validating the signature... This is incredibly good news - hex-editing the firmware image causes the signature to change.

This points to the possibility of a fully customized ROM some time in the not-so-distant future.
[myTouch 4G Android Development] travisjames:
No, the file is still validated in HBoot, but to be able to flash older firmware images, it has to think that the phone is either on that firmware or an older firmware than the one you are flashing.
[myTouch 4G Android Development] geech_:
just recieved MT4s via ups yesterday , download link just came to the phone a tmobile update so i take it i shouldnt download it???
[myTouch 4G Android Development] krypto16:
No you can apply it and it will upgrade you from 2.2 to 2.2.1. This thread only gives instructions to downgrade to the original release since this is sometimes required to gain root (At least for the MTSLIDE you had to downgrade to the ENG build to gain perm root). Travis was just giving the process to downgrade the MT4G since no one else had taken the time to figure it out and provide instructions.

I am on 2.2.1 and VISIONary still works for temp root and I am able to "freeze" apps which is the only way to really "remove" the bloatware so it does not come back on each reboot without having full root.

I could be wrong but applying the update has caused me no issues. What is the harm in updating if there is a process to undo the update if need be.
[myTouch 4G Android Development] timbo1083:
Worked exactly how you said it. I just did it. Thank you so so much. Now I can root properly after making my own back ups. Thank you again.
[myTouch 4G Android Development] travisjames:
Actually, when you're on the stock MT4G build, you can't root the MT4G....sorry to tell you.
[myTouch 4G Android Development] Kline:
This worked like a champ to re-flash my existing 2.2, just did not need to edit the img file (placed zip on sdcard and flashed). All my bloatware came back merrily :P
[myTouch 4G Android Development] cl2eep:
Update! Not getting the ota will prevent you from rooting! Also, shouldn't this guide be taken down? Downgrading at this point does more harm than good.
[myTouch 4G Android Development] likeitnot:
I rooted my mytouch4g and turned SOFF however I am having to send the phone back due to a defect on the actual hardware. I followed the instructions in the rooting thread to turn the S back to SON. Now should I also do this setup? Or will I be fine sending it back with the SON and they won't know a thing? Just making sure before I send it back Tuesday.

Plus I need to do more research on this method cause I'm not sure what a hex editor is (noob) but thanks for the post!
[myTouch 4G Android Development] timbo1083:
So true. That's why I went back today and exchanged for a new phone. Hoping to get update on that much quicker then the one I just turned back in.
[myTouch 4G Android Development] slhpss:
Please make sure you run alogcat for the rest of us and let us know the link when your update comes then. Thanks
[myTouch 4G Android Development] likeitnot:
Is this basically "unrooting" ???? I ask cause I think I need to do this simply cause I deleted a few apps (apppack, amazon mp3, monopoly, ashphalt demo, and mytouch videos) and even after turning S back to ON and doing a factory reset they are not there and now I'm kinda nervous they will catch I rooted it because I have to return it for a new one.
[myTouch 4G Android Development] slhpss:
yes, but you will have to turn S-OFF again before doing this... it will turn it back to S-ON in the process and it will return it to stock firmware with all the apps you deleted back in place
[myTouch 4G Android Development] likeitnot:
I have S-On right now. So since it's S-ON I should go ahead and do this then and it will return the apps?

I will give it a go even though I am not sure about this hex editor. I downloaded one called HxD. All it is when I open it is a grey box lol which some greyed out options so Im assuming once I drag the particular file I need to it it should work.

Thanks!
[myTouch 4G Android Development] Kline:
FYI you don't need a "hex editor" per se. You can open the file fine in notepad and just find the appropriate version number to edit; it will just be formatted funny.

edit: Yes, I did my own re-flash of stock using notepad. Not a hex editor.
[myTouch 4G Android Development] johnowa636:
Has anyone who downgraded from 2.2.1 to 2.2 been able to received the update back to 2.2.1. I for one have not received update.
[myTouch 4G Android Development] slhpss:
I don't think anyone has D= but I have logs running constantly... so if I get it I will post I hope others are doing the same.
[myTouch 4G Android Development] likeitnot:
I had to unmount on 3 and 13 like you said firstly for it to even take my commands... unfortunately I when I tried it the first and second times and put it in hboot it never scanned for the package =( So I don't know what Im doing wrong. Im about to do it all again and see how that goes.

FTR. after I put the last command in and power off my device should I keep the phone connected to the computer? Just asking lol (I did the first time and didn't the 2nd time, both obviously unsuccessful).
[myTouch 4G Android Development] slhpss:
I'm pretty sure you're gonna have to S-OFF before these instructions will work
[myTouch 4G Android Development] travisjames:
I don't think that anyone has been able to receive the OTA update after doing this. I will add that bit of information to the OP.
[myTouch 4G Android Development] likeitnot:
Yeah not sure what Im doing wrong. Every time I do it it scans and I see a bunch of orange text and some say no image or wrong image...? I know Im doing it right... or thought I was

*edit* I've done this going on 6 times now and no such luck.

I always delete the misc images and the rar folder on my sd card before I try it again so its fresh (I do notice though that no matter what after I put in the first command and then take the misc image from the sd card when I open it in hex the numbers are already 1.14.531.1 ... The first time I did this of course they were 1.17.531.2 , but now every time no matter what they are already set at the earlier) and I follow everything to a tee I am almost certain. Not sure. I see every time its searching in hboot the green texts says wrong image, no image a few times.... any idea what I'm doing wrong?
[myTouch 4G Android Development] likeitnot:
I also put S back to OFF just in case (even though I later learned I didn't even have to do that but I wanted to try everything I could). =( bummer

*edit* still a no go. This is crazy. I need to get it flashed back before I have to send it back to Tmobile Tuesday. Anyway suggestions/help would be amazing. Thanks to you all.
[myTouch 4G Android Development] likeitnot:
any suggestions would be amazing. Thanks guys.

*edit* I figured it out, I took the ".zip" off the rar file so instead of renaming it "PD15IMG.zip" I put it as "PD15IMG" and that's it. Worked beautifully! Thank you so much for all of this.

Weird how the simplest of things can make ALL the difference.
[myTouch 4G Android Development] JWhipple:
Can anyone say that they had received the OTA, followed these steps to go back to stock, and then got the OTA again?
[myTouch 4G Android Development] slhpss:
I don't think so.... I know I haven't... but I have been harassing customer support and trolling these forums for a link to appear... and running a constant logcat...
[myTouch 4G Android Development] johnowa636:
Some one needs to take one for the team and open a new line if service with Mytouch 4g. First thing you install is "aLogcat" from market to get the download link. Return it withing 14 days and get money back minus days it was in service. I plan to upgrade my wife within two weeks otherwise I would do it.
[myTouch 4G Android Development] johnowa636:
I doubt anyone who downgraded software has received update.
[myTouch 4G Android Development] slhpss:
I do know this after looking around a bit... People who did not downgrade, but chose not to upgrade OTA and subsequently restored also haven't received the update... SO we'll probably get it... we just have to be patient... if I get it the link will be up here within 5 minutes...
[myTouch 4G Android Development] borodin1:
I get my phone tomorrow, I'll see what I can do.
[myTouch 4G Android Development] daewond3r:
I just got the notice of the OTA and postponed it an hour. I'm downloading aLogcat right now. How do I get the link once it's done?
[myTouch 4G Android Development] momohammed20:
if you already got the update notice, then it's too late to run alogcat, because it already has the firmware downloaded to the phone. I actually just got a notification that an update was ready to install, it looks like everyone is starting to finally receive the update? By the way I tried downloading alogcat, and i did not find anything in there.
[myTouch 4G Android Development] allen099:
I had logcat running via Terminal on the Mac and the OTA came through. I did some searching though and I can't find the google server. The package is called OTAPkg.zip though. Does anyone know what I'm looking for, be it http or ftp? I did a find on the logcat and couldn't locate anything.
[myTouch 4G Android Development] slhpss:
I don't know mac, but since it's based on bsd I'm assuming (maybe incorrectly) you can use cat and grep??? if so whatever you saved the log files to just do a cat filename | grep .zip and it will spit out lines with .zip in them.... if I'm wrong then... can you open it in a text editor or something and do a find .zip ???
[myTouch 4G Android Development] s10shane:
hey i need help. i get lost step 6, i type it in and i get an error or something like that, then i dont know what misc.img ur talking about? im new to this mt4g so im not sure how to do this. plus i dont know what Hex Editor is.
[myTouch 4G Android Development] allen099:
Sorry I forgot to include that...I actually did EXACTLY that, copied to Text Edit and did a Find on .zip...I only got two returns with OTAPkg.zip but no IP/domain. I'll have a look again this evening. Lots of lines to crawl through ;-)
[myTouch 4G Android Development] ikm19:
Did Anyone got OTA update after downgrading from 2.2.1 to 2.2 ?
[myTouch 4G Android Development] slhpss:
Is there anyway you can grab that zip off the system and post it up here. I would like to take a look at if possible
[myTouch 4G Android Development] allen099:
Yeah absolutely. What's the path where OTA's are typically saved?
[myTouch 4G Android Development] travisjames:
/cache/fumo/OTApkg.zip

if I'm not mistaken.
[myTouch 4G Android Development] s10shane:
ok i did everything right but i cant get The phone to scan for PD15IMG.zip and ask me to flash it. idk why it wont ask me to flash it. keeps saying wrong image. please help!
[myTouch 4G Android Development] slhpss:
I got the boot loader to accept it as an update and flash it... it even gives me "OK" for everyone and update successful, but when I reboot it's as if nothing happened :(

it seems as if the files located in the firmware.zip file inside OTAPkg.zip are the same as the original firmware... thus the reason for no changes...
[myTouch 4G Android Development] likeitnot:
Same thing happened to me and I kept doing it over and over and over... FINALLY figured it out. Drop the ".zip" off the end of the rar file so it just reads PD15IMG instead of PD15IMG.zip

TO O/P: I also found that I had to do the unmounts that you currently have as crossed out on the original post. Just in case someone else might be running into a problem. So I say they are absolutely needed...at least they were for me!
[myTouch 4G Android Development] likeitnot:
Oh wow, talk about a bummer. Not sure what to say so I'm sorry :( Hopefully one of these smart people here can help you resolve this issue!
[myTouch 4G Android Development] cl2eep:
Don't downgrade! There is currently very few reasons to downgrade, and a whole host of reasons not to. If you downgrade, you will very likely NOT get the ota again, and with out the ota you CANNOT ROOT. The OP says this about 4 lines into the instructions. Also, if you don't know what a hex editor is, don't do anything involving one.
[myTouch 4G Android Development] slhpss:
Ok... finished my daily harassment of T-Mobile and this time I'm being told the 15th of December, though I know they've said 15th of November multiple times.. this one also told me as another did that it will not update if connected to Wi-Fi... which to me is unacceptable... basically the idea is to not use wifi at all, and for some reason my mobile data seems to be sporadic though I always have at least 3 bars and an H... kinda frustrating...
[myTouch 4G Android Development] cdw9800:
Someone posted the ota in the general forums I would upload if needed
[myTouch 4G Android Development] slhpss:
Already grabbed it from there... working on getting it to flash properly... at this point I have managed to get S-OFF again!!!! and am working on making sure I have all the update working properly and am checking one or two more things... (I will post instructions once I work through this and verify everything is functional... at this second wifi isn't working)
[myTouch 4G Android Development] slhpss:

[myTouch 4G Android Development] ikm19:
Now i am downloading and see if it works ...

Edit: I was able to upgrade but was not able to su in terminal even though visionary+ reports that device is already rooted and in bootloader S=off

Edit: Okay i found solution in this post

http://xdaforums.com/showpost.php?p=9262745&postcount=853

it says error in terminal that file exists but still after reboot it works perfect.
[myTouch 4G Android Development] allen099:
Sadly only thing in /cache is lost+found folder. No .zip. Does the phone wipe the downloaded file afterwards? I sent myself the text logcat and am going through it now.

Edit: You're correct, according to the logcat. Looks like it may self-delete after the install. I know I didn't delete it myself. I ran a search for OTAPkg.zip, fumo, and OTA in root explorer; got nothing. Also searched through .trashes folder, nothing.

Logcat:

[myTouch 4G Android Development] kingjavi:
@slhpss- Im having trouble with this. I have followed your steps and my phone is now laggy and doesn't acquire s=off. I admit I downgraded after already having perma-root for some dumb reason but have not recieved the OTA since as many others. Is this method of your posted here really working and if so what could I be doing wrong?
[myTouch 4G Android Development] slhpss:
Yes it does work... I'm working with the stuff ikm posted right now to verify if I can get full root back... once I verify all this I will be more than willing to work with you one on one to help you out. I was in the same boat as you and last night I said screw this I'm gonna punch this thing in the face until it works... and so far so good
[myTouch 4G Android Development] travisjames:
It's travisjames, not JUSTINTRAVIS! :] haha

I get the su error also. It says device is rooted, but SU force closes.

Once we get this worked out completely, we can start a new thread.

I think you need to put up new post as not everyone read this thread. Most of them think its downgrade thread why they need to read it.
[myTouch 4G Android Development] travisjames:
Actually, slhpss, remove your instructions from this thread and start a new thread please!

Thanks a lot!
[myTouch 4G Android Development] brian6685:
I'm confused, it says to force the ota on that thread. Will this help Mr perma root my device since I have not gotten the ota?

[myTouch 4G Android Development] slhpss:
I think you should be able to flash pd15img.zip without adb.... try running the one in this post... if it doesn't work try running the one in my post about forcing the update... but you should be able to flash img files in fastboot I don't know if s-on is going to affect that ability though...
[myTouch 4G Android Development] JWhipple:
Curious - why does your boot screen say VISION when it should be GLACIER ?

Are you trying to use this on your G2 ?
[myTouch 4G Android Development] slhpss:
good catch... notice the output from his devices too... it should start with SH... make sure you guys follow instructions specific to your devices :)
