Does anyone have a copy of the "PG41IMG-WIFI.zip" file from Globatron's original post so I can downgrade from my Honeycomb kernel. I apologize if this has already been asked recently. Many thanks in advance if you could point me in the right direction!

[HTC Flyer, EVO View 4G] M@|ice:
Globatron, did those files help any?
[HTC Flyer, EVO View 4G] M@|ice:
Also, forgot to ask, but trying to flash say...leedroids gingerbread rom on it wont do anything right? I don't actually want the stock gingerbread rom back, Im just trying to get a gingerbread anything preferably that specific rom back on my flyer. Have no interest in going back completely stock. Maybe a stupid question, but I'm learning this as I go. Thanks anyone for input.
[HTC Flyer, EVO View 4G] DigitalMD:
If you are on HC attempting to flash any GB based ROM stock or custom will not work and might put you in a perpetual boot loop situation. If you cannot revert to stock using the RUU method you are stuck on HC until someone finds another method to revert.
[HTC Flyer, EVO View 4G] tangcla:
So am I right in saying, for a Wifi-only Flyer, once we go to Honeycomb we can switch between different HC ROMs, but won't be able to get back to Gingerbread?
[HTC Flyer, EVO View 4G] M@|ice:
For the time being, correct. Globatron is working diligently on changing that for us. :)
[HTC Flyer, EVO View 4G] DigitalMD:
There is a European version wifi only which has a usable RUU, but you are correct for the US models.
[HTC Flyer, EVO View 4G] tangcla:
I knew I shouldn't have bought a Flyer from you Americans! *sigh*

I should have bought the 32GB 3G Flyer...
[HTC Flyer, EVO View 4G] DigitalMD:
Don't worry , once the US invades and conquers:D Western Europe, you can have all the 3g you need.
[HTC Flyer, EVO View 4G] tangcla:
Is it worth going to Honeycomb on the Flyer? It seems really nice on the Xoom - how does Honeycomb work since the Flyer already has hardware buttons?
[HTC Flyer, EVO View 4G] globatron:
It might be possible but not with the current boot image, the boot offsets for the two hboots are different, and there will most likely be a mismatch in the RIL and radio, but given that the wifi model doesn't use a cellular radio it just might work.

Send me a PM if you want to try and I'll rebuild Leedroid's boot image for you with the HC hboot address.
[HTC Flyer, EVO View 4G] globatron:
The hardware buttons are disabled. If you have a US wifi flyer, then I would suggest waiting until we have a revert method.
[HTC Flyer, EVO View 4G] globatron:
It allowed me to confirm one behavior when running an RUU, but not everything I was looking for.
[HTC Flyer, EVO View 4G] DigitalMD:
This looks like it might be promising as a way to switch between GB based custom ROMs and HC for us US wifi owners. Any way I can help? I am running LeeDroid now. I don't want to be stuck with HC because at times I need the camera to work with Skype, but I certainly like to play with HC a bit.

Thanks
[HTC Flyer, EVO View 4G] M@|ice:
If I make a backup in recovery before flashing the leedroid rom should I be able to restore that backup? I'd like to try it since you think it "just might work".
[HTC Flyer, EVO View 4G] tangcla:
The nandroid backup won't make a copy of the hboot.
[HTC Flyer, EVO View 4G] globatron:
You'll probably be restoring that first, then using fastboot to flash the kernel / boot image.
[HTC Flyer, EVO View 4G] globatron:
Hboot backup has nothing to do with what I'm suggesting, the hboot will still be the HC hboot.
[HTC Flyer, EVO View 4G] cnewsgrp:
I know asking for status is not polite (but will ask anyway :))

Any progress on this for US BestBuy Wifi Flyer? I am asking because we need to revert to GB to install new leak.
[HTC Flyer, EVO View 4G] aostl:

[HTC Flyer, EVO View 4G] globatron:
Currently waiting on a unit to test with. It's pretty much impossible to dig into this any deeper without a device to work with.
[HTC Flyer, EVO View 4G] aostl:
Be glad to test for you
[HTC Flyer, EVO View 4G] globatron:
Thanks, but there is nothing to test until I can spend time working with a device, doing it remotely really is not an option.
[HTC Flyer, EVO View 4G] lpasq:
globatron:

I will help fund a project to assist the US Best Buy WiFi Flyer community revert to OEM GB both for our ability to flash leaked HC ROMS and the future OEM HC as well as in anticipation of ICS.

I can donate a large portion of the cost and ask other to donate as well so you can purchase and have shipped a US Best Buy WiFi Flyer.

I expect you would need to buy from an indirect reseller and the cost would be greater than if someone bought one at a Best Buy and shipped it.

If you were open to support us and purchased a device from here (for example), then you post the dollar amount in US$ you need.

I will start the donation drive and pledge $200...
[HTC Flyer, EVO View 4G] mcord11758:
Kind of wish I fully understood the best buy flyer limitation before purchase. It is not a total deal breaker but it sucks to be limited
[HTC Flyer, EVO View 4G] schalmers:
Wouldn't this be a better less expensive option? $275 on ebay

http://www.ebay.com/itm/HTC-Flyer-p...20804253348?pt=US_Tablets&hash=item1c207e9ea4

Or someone going into a Best Buy and sending it to him. I am in France so I can't do this but I am sure someone in the US could do this,
[HTC Flyer, EVO View 4G] lpasq:
Yes it would be a better option and I am still pledging US$200 to OP's PayPal..........
[HTC Flyer, EVO View 4G] RMarkwald:
Tomorrow is pay day. I will transfer $25 towards the OP to help. Will be done by 8:30 AM CST.
[HTC Flyer, EVO View 4G] lpasq:
Nice. That's $225 total so far but we do not yet have a confirmation that OP is interested. We should know soon plus I have a PM asking him and will post here with response and also let you guys know.
[HTC Flyer, EVO View 4G] globatron:
I will get a Best-Buy Flyer irrespective of donations, however donations are welcome.

I am bidding on a few on ebay for three reasons 1. Cost ; the cheaper the better 2. There is currently no best-buy stock 3. On ebay I can check that is is a best-buy model; the risk of buying from an online store is that it is an actual WWE version which won't work for my purposes.

I had intended originally to get one picked up in Best Buy this week but the stock situation doesn't allow for that.
[HTC Flyer, EVO View 4G] lpasq:
Great. I donated as committed :cool:
[HTC Flyer, EVO View 4G] RMarkwald:
The $25 I promised has been sent as well. Thanks for undertaking this, we really appreciate what is trying to be done for these US BB Flyers!

Hi everybody here.

I am attempting to revert from HC to GB. Sadly adb cannot find device, and my pc (windows 7 x64) fails to install device drivers for my Flyer.

How can you help me please?
[HTC Flyer, EVO View 4G] drgrabez:
proper RUU??

Hi guys ! I really need your help?

How to know what is appropriate RUU for my device?

I bought it (3g+wi-fi)e days ago from eBay,and custom HC is installed. I want to downgrade it to GB (really bad battery duration and camera sometimes doesn't work), maybe leedroid one- but I don't know which RUU is proper from the list? What numbers should I look?This is my first android device-I am old school win mobile guy.

Really appreciate your help!
[HTC Flyer, EVO View 4G] globatron:
boot it to fastboot and run the following fastboot command, you can find the tools you need for this in post #1

fastboot getvar cid

Post the result of that.
[HTC Flyer, EVO View 4G] drgrabez:
Thanks! You are great and fast! :)

and sorry I must ask, how to enable usb debbuging mode?

And why do we need fastboot and adb tool for windows and linux?

I am really noob for android excuse me:confused:
[HTC Flyer, EVO View 4G] globatron:
You don't need to enable usb debugging, just install the fastboot drivers ( and uninstall htc sync if installed ), reboot to fastboot mode ( bootloader then select fastboot) You need to give me the version you hardware expects, not the version that the SW gives, hence the use of fastboot.

Fastboot drivers: http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe
[HTC Flyer, EVO View 4G] drgrabez:
I installed drivers, uninstalled htc sync, then restarted pc, then conneceted flyer to pc-default connection type is >disk drive<, then restarted flyer-fast boot is selected under settings/power/fastboot, and nothing happens?

where did I wrong?:(
[HTC Flyer, EVO View 4G] mcord11758:
You have to run the command listed earlier
[HTC Flyer, EVO View 4G] drgrabez:
where to type the command, nothing happens-only see installed htc driver, when I click on it I get >uninstall HTC driver<

Can this help, friend send me images of his flyer that have installed official shipped rom that I need, for reverting to GB?

[HTC Flyer, EVO View 4G] mcord11758:
others are better to explain but if in windows you need to open a terminal then change directories to where Fastboot is then enter the command, I believe
[HTC Flyer, EVO View 4G] globatron:
Turn off fast boot in settings->power

Power-off the flyer

Power on while holding the volume down key

using the volume keys select fastboot from the menu, then briefly press the power button to select.

This puts the phone in fastboot mode.

Open a command prompt in the directory where you extracted the zip file and run the commands listed above.
[HTC Flyer, EVO View 4G] DigitalMD:
You should review the following on installation and use of ADB before attempting this

http://www.addictivetips.com/mobile/what-is-adb-and-how-to-install-it-android/
[HTC Flyer, EVO View 4G] globatron:
No, the commands I specified were for fastboot, not adb.
[HTC Flyer, EVO View 4G] DigitalMD:
Oops, sorry about that. I was't thinking.
[HTC Flyer, EVO View 4G] drgrabez:
I am desperate! I do not see any zip file?

where to put command?

If you have never used a windows command and or adb I would suggest you tubing some videos for adb. You need to use fast boot but the process as far as entering the commands is similar

I had a feeling that if Football posted it, it was legit, so I went with it. People just will need to re-lock their bootloaders first, then run the RUU. I don't know what would happen if the bootloader was unlocked, I'm guessing fail...?

You shouldn't need to do the misc_version, a simple RUU should be enough. There were no OTAs for the BB flyer and the only upgrade method was Paul's which did not touch the version-main.

Hmm, 1530 is not a BestBuy location number. What is the CID of your flyer? It's BS_US001 then yes use 2.27.1540, otherwise let me know what it is and I'll see which RUU will work for you (if any)
[HTC Flyer, EVO View 4G] vega89xi:
Just an FYI.

I have a TMO US 4G Flyer and was already running the first leak from Paul. I don't have an RUU for TMO US Flyer so was unable to revert to GB. I thought what the hell and tried just flashing the update zip after a full wipe and it worked without a problem. Booted, all radios work, and no shutdown problem.

I just down (GB) and upgraded (NOV 10 Leak) my own Flyer and it worked perfectly. It was a german Flyer (WWE 1.32.xxxx) and i had a RUU.

Now i need to do the same with my mums last month bought US Best Buy Flyer.

Can i use the same method? Which RUU do i need?

Software 1.36.1540.32, Kernel 2.6.35.10-gb1cf1af, Build 1.36.1540.32 CL50442

Where do i get the CID if you need it for answering my question?

Thanks!
[HTC Flyer, EVO View 4G] lpasq:
do you not have a windows machine to follow the OP? otherwise, the instructions provided in the above few posts worked for my flyer which is also a 1.36 like your mum. grab the 1.36 zip and place in your androidsdk folder where fastboot is located and follow fastboot commands as listed by globatron. a second pass of the flash might be called for but it is a smooth and simple process. (no guarantees)
[HTC Flyer, EVO View 4G] Dacoco:
So i just need to download the 1.36 RUU from globatron and execute

fastboot oem lock

fastboot erase cache

fastboot oem rebootRUU

fastboot flash zip RUU_Flyer_BrightstarUS_WWE_1.36.1540.32_R_Radio..zip

?

And after that? Run the RUU? Is it this what you meant with second pass?
[HTC Flyer, EVO View 4G] lpasq:
the four listed fastboot commands might do it. if you get a message about hboot error, then you fastboot flash zip RUU_Flyer_BrightstarUS_WWE_1.36.1540.32_R_Radio..zip a second time. that is what is meant by "a second pass" at the flash. sorry for not being clear.
[HTC Flyer, EVO View 4G] Dacoco:
Great, thanks. So it's just the zip and no normal RUU (executable) like in my case. Understood :-)
[HTC Flyer, EVO View 4G] lpasq:
correct. the "fastboot method" does not utilize ruu executable and instead is a straight forward fastboot flash method of a zip that is placed with fastboot in your sdk tools folder. the fastboot command for ruu places device into ruu mode and then fastboot flashing the zip is allowed.
[HTC Flyer, EVO View 4G] nikkineko:
Best Buy wifi flyer updated to newest leak. followed downgrade instructions. downgrade was a success.

Thanks globatron! Successfully downgraded to GB. Your the best.
[HTC Flyer, EVO View 4G] nickgbg:
Sorry for the silly question, but I just want to be sure (I'm a little bit afraid from possibility to brick my device):

For EU 3G Flyer downgrade/revert from HC (second leak - 3.401, followed Paul's guide with HTC unlock) I have to try to directly apply the right RUU and only if I receive the error message for old version I should follow the procedure from post #1? Am I right?

Or should I follow strictly the procedure without trying RUU?

And what about if I want to go not for stock but to custom GB ROM instead?

Thank you in advance.
[HTC Flyer, EVO View 4G] globatron:
If you only ever followed Pauls guide you should simply need to RUU. If you do need to follow the full guide you'll get the error when you try to RUU but no harm will come of that, you just boot back up and run through the full procedure. No harm will come of trying to run the RUU if you need the full procedure and run the RUU first, it will fail before making any changes at all.
[HTC Flyer, EVO View 4G] nickgbg:
Thank you very much for your quick and detailed answer!

P.S.

When I tried with RUU (I tried this 2 times on 2 different machines) I'm stuck at 16 % with device's whole screen with smeared colored lines.

After device restart I still have HC.

Is it safe to follow your procedure (this is not exactly the case with error "Main Version is older! Update Fail! Press <POWER> to reboot").

Thanks again!
[HTC Flyer, EVO View 4G] x1123:
I was one from followed Paul's guide and just run RUU at xp 32 machine and failed : ERROR 140 : bootloader version error :(

Then I follow your guide on ubuntu 10.04 x86 (as my familiar OS) and successfully downgraded.

Many Thanks.
