unable to downgrade from 2.3.4 - myTouch 4G General

I have a My Touch 4G currently running 2.3.4 that I want to downgrade to 2.2.1 so I can root it. I am unable to get it to take the PD15IMG.zip to take once I hit the bootloader. It says its extracting fine, but the phone never reboots and if I manual reboot it, it boots up on 2.3.4.
I was using the following instructions.. cyanomod instructions and I did everything fine but get stuck with step 8.
Here is a copy of my ABD session:
Open to any suggestions.. I did some searches but no luck.
I tried to paste the URLs for the pastebin and the instructions I used but was blocked because of the stupid spam rules for newbies.. so PM me and ill send them to you.
Also as you can see I have been a member for over a year now, I just do a lot of lurker so I don't post much. I usually can find my answer searching without asking but I am stumped on this one.

This exact same thing happened to me.
The problem was that ADB wasn't pushing the entire PD15IMG file to the SD card. Every time I tried it it was missing exactly 53 bytes. (You can check this by looking at the file size of the PD15IMG on your hard drive and see if it file size matched EXACTLY on your SD card down to the single byte.)
I fixed it my using the file manager on my computer to just drag and drop the PD15IMG file onto the SD card. For some reason that transferred the entire file without problem.
I ran through the steps again and viola, 2.2.1 upon reboot.
You might also have a corrupted PD15IMG file. You can fix that by re-downloading the file, preferably from a different source just in case.

why u need downgrade 2.2.1 ?

@skipjacks - ill try that, on the 2nd attempt at it yesterday I manually copied of the file over after I downloaded it from another source, yet it still would not upgrade. I will give it a 3rd shot and report back.
@Ridofu - I am tried of having the HTC offical software crashing on me. I would like to root and then install CM7.1

Same thing..
I downloaded PD15IMG.zip manually over the HTC E:\ drive I have mounted.. did all the commands again, went to bootloader, it says it installs but then never reboots or does anything...
the image say loading, and I see a blue bar on the right top corner... then it switches to checking with a yellow/orange bar in the right top corner..
then it just goes back to the main screen and doesn't do anything..
all i see is fastboot, recover, factory reset, simlock, image crc
Id love to run the adb shell md4sum /sdcard/PD15IMG.zip but everytime I run it it comes back with md5sum: not found
Any ideas?

How I rooted my MT4G
Try this guide:
http://androidrootking.blogspot.com/2011/10/how-to-root-your-mytouch-4g-original_12.html
This is a step-by-step guide to root your MT4G. It has a link to another guide that will help you downgrade your phone.
You must downgrade FIRST, in order to root, because the root tool (gfree) DOES NOT WORK with Android 2.3, it only works with 2.1.
If you really like GingerBread, and want to keep root, go here AFTER you're rooted:

—E!

Do you have MicroSD card reader in/for your PC?
Try to use it instead of copying the file through the phone.

@Ericm301 that is the exact method I have followed and it does not work. I have done the Push method, I have done the copy via USB cable to the E:\ drive that is mounted and neither allow me go to bootloader and load the file.
@Jack_R1 I will try getting a Micro usb adapter and copying the file over as well.

I tried taking the SD card and copying the file manually, I also tried to use the file from a 3rd source. It will not downgrade. I can post a video if you want to see it fail.

Just wanted to give a update. I did the manual downgrade 2 or 3 more times and I finally gave up on it.. then I switched to Fastboot Downgrade method and it worked perfectly the 1st time..
man what a frustration!

Struck by an MDA brick!!

Made a huge error.....didnt go through forums and read instructions before trying to Flash a German T-Mobile MDA Compact to a English ROM....
The device is completely dead....
Followed all the steps required to get it back up...It is refusing to do so though....
Used this thread:
http://forum.xda-developers.com/viewtopic.php?t=19500
One thing to note is that I am not using the AC charger, am using the USB cable to charge the phone.
Can someone please helpme...
Haven't got past the bootloader mode...
If you followed the instructions from the other thread, it should have started flashing.
Some things to check on:
1) Did you do a full d2s before you attempted the upgrade? It's always good to have something to fall back on.
2) If you can get to a bootloader screen, all is definitely not lost.
3) Sometimes, it takes 4 or 5 minutes for the "Press to flash" comes up on the screen so be patient with that.
4) Make sure you did exactly a 416 byte copy from the original rom file in to the new flash file.
5) You can only write an nb1 file from the pc AFTER it has been created from the pocket pc. If the SD card has been pc formatted, the nb1 file will write to it but the pocket pc won't recognize it and will just sit there at the bootloader screen.
HTH
I think I fired the MDA
Well I did not create the nbf file from the ppc, downloaded it from the the forum FTP. I do not have the backup of the nbf file. As I mentioned I did not read the forums before trying the update.
I just downloaded the T-Mobile ROM update and tried installing it. Obivousioly it didn't work, Game the dreaded the 112 error in the 3rd step.
Am not even getting the bootlader screen now..
Any ideas on how I can get this device up and running.?...
ok, need some clarification here. "What" are you trying to load (nbf files or nb1 files) and how are you trying to load them (SD flash or the standard USB based upgrade)?
Easy enough to check to see if your device can still get to bootload mode....hold the camera and power switches in at the same time and hit soft reset with your stylus. After letting go of those and you see either "Serial" or "USB" at the top of the screen, you should still be able to recover from this.
Tried with the nb1 files not nbf (sorry abt teh error)..
The bootloader screen was showing up ...unitll I tried the T-Mobile MDAcompact_vers11201
After the 112 error while updating...the device now refusing to get to the bootloader mode.
Have I fried the device and made it unusable....?
hey just got back the bootloader screen...
Take the SD card out, disconnect the USB and tell me what happens when you hold the power and camera buttons in at the same time, then hit the soft reset.
Also, has the unit been charged recently?
Its showing Serial v1.00...after the reset.
Its been on the USB chatge all along.....
Great. If you get Serial at the top, this can be recovered.
If you want a good T-Mobile 1.12 rom file, go here and use this one:
ftp://ftp.xda-developers.com/Uploads/Magician/tmobile-uk_wwe_ROM_1.12.00(thereapermanl).rar
Unpack it and follow all the procedures about copying the 416 bytes, rewriting the file, etc. from the other thread. I have tested this rom file and it installs ok.
Thanks for the encouraging words...
Will it work even if I do not have a backup of the original ROM on my machine?....I only have the tmobile.nb1 file which I got from the XDA forums.
Lemme try using that and editing it.
Thanks a ton for your help.
You might be a little stuck for an nb1 flash if you don't have an original flash back up but don't fear. You can go here and get this WWE1.12 file and just do a USB type upgrade:
ftp://ftp.xda-developers.com/Magician/Shipped_ROMS/WWE_11200_128_11210_ship.exe
I know this one works too. It's ROM 1.12, Radio 1.12 and Ext_ROM 1.12. When you try to run the upgrade program though, it might give you a Country ID error. If so, use the attached upgrade program instead. If this one gives you a Country ID error again, close the program and just run it again. I've been down all these roads already.
Lemme get this right this time: I will be doing the following
1. Install the ROM as you have mentioned. With the country id hack if necessary
2. Hopefully by now the device would be alive. If so will take a backup of the ROM on the SD card
3. From then on follow the instruction given in the doc.
Hope I get it righ this time else Its going to be a long night for me.
Lemme know if I have to do anything else.
Either ROM will work fine for you. It just depends on whether or not you want I-Mate stuff on it or T-Mobile stuff on it.
Doing the USB upgrade will put the I-Mate ROM on but after that, it should be working and you can then do an SD backup, follow the SD flashing procedures and get the T-Mobile ROM on.
Good Luck!
The masupgrateut is throwing up a ruu.dll error?...you seen that one before?
What sort of error? Not found?
yup...
I extracted the ROM exe and found teh file...copied it to the windows folder..and ran the no id program...no error this time round but the update is still giving a COuntry ID error...
Been looking at various posts...specially this one...
http://forum.xda-developers.com/viewtopic.php?t=14973
Thinks thats gonna help?
ok...two things.....just run it again. The no ID program sometimes does that on the first time 'round so just run it again.
Second, stick this at the end of the RUU.conf file:
[CHECKCEID_TYPE]=1
ran the program multiple times...still getting the COuntry ID error...
Are you running this program? MaUpgradeUt_noID.exe
...with the change in the RUU.conf file?
I just noticed something....did you extract all the files to a single directory and just run it from there or did you just pull a few out?
ALL the files have to be in the same directory. This is also where you need to execute the installer program.

[HOW-TO] Hey Noobs ... Here's help when you think you "bricked" your phone (U.S.)

[HOW-TO] Hey Noobs ... Here's help when you think you "bricked" your phone (U.S.)
Since we have apps now that seemed to have inspired G1 noobs to root and flash their phones without the prequisite of reading the instructions, I hope they might read this to help them get out of the "bricked" situation they often find themselves in. It's simple to do, it's saved my ass a number of times, and it will quickly get you back to a pristine T-Mobile status.
NOTE: This is for U.S. T-Mobile users. Your mileage my vary and it may need to be adapted with different files relative to your country and carrier.
You are not bricked if you can get into the recovery or bootloader just jammed up!
How to quickly UN-"brick" your phone:
All you need are two files.
DREAIMG.nbh
update.zip
THESE TWO FILES ARE FOR THE CONVENIENCE OF PEOPLE IN THE U.S.These can be downloaded at:
- http://www.brentcctx.com/android/DREAIMG.nbh
- http://www.brentcctx.com/android/update.zip
DREAIMG.nbh is the original T-Mobile U.S. Rom.
update.zip is the original T-Mobile U.S. "cupcake" update (signed-kila-ota-148830.de6a94ca)
Download these two (2) files and put them on the root of your sdcard and restore the original T-Mobile rom. You will do this by
remove the sdcard from your phone
put the sdcard into your card reader
put the card reader into your computer
make sure your computer recognizes the sdcard with a drive letter (Windows) or is mounted (Linux)
look in the root directory of your sdcard for any file named "update.zip". If one is there, delete it.
copy DREAIMG.nbh to the root of your sdcard
copy update.zip to the root of your sdcard.
double check that DREAIMG.nbh is spelled just like that (with DREAIMG in all caps and nbh in lowercase)
double check that update.zip is spelled correct and the whole thing is lowercase
safely remove the card reader from your computer (unmount in linux or eject properly in Windows)
remove the sdcard from the card reader
make sure your phone is off
put the sdcard back into your phone
press and hold the CAMERA button
while still holding the CAMERA button, press the POWER BUTTON (red button on the bottom right of phone)
at this point, you should see the phone checking your sdcard, looking for DREAIMG.nbh and checking it for errors
wait until you see "OK" beside all the different items and instructions at the bottom of your screen.
now, press the POWER button (red button on the bottom right of phone) which will restore DREAIMG.nbh
wait until everything has completed.
reboot your phone
your phone will also write the old, original radio back to your phone too and reboot itself
your phone will now boot into the recovery screen (if it didn't, start over with #1)
you should see the triangle with a yellow exclamation point ! (again, if you don't, start over with #1)
Now that you are in the recovery screen, that means your phone has been restored to the original G1 factory condition. Note: you have also lost root at this point, your radio is back to the original and, if you had a different SPL, that's been replaced as well.
While still in the recovery screen, it's now time to update your phone to "Cupcake". This is the OTA version from T-Mobile. It is not rooted or modified. It is strictly the OTA update.
Open up your keyboard and press ALT + L to go from the triangle/! to a menu
For safety sake, press ALT + W to wipe your phone (it should have already occured, but we're being safe)
Now we want to apply the sdcard:update.zip by pressing ALT +S
Wait until the update completes and you see instructions at the bottom of the screen.
Follow the instructions to reboot your phone.
At this point, your phone will update the radio. Be patient and wait for the phone to reboot itself.
Your phone will reboot into recovery again. All you need to do at this point is reboot your phone by pressing HOME+BACK.
You will have to be patient again while your phone boots for the 1st time with "Cupcake". If, after 5-7 minutes your phone hasn't fully booted, that means you have done something wrong. Start completely over.
If at any point during the process you get a warning that DREAIMG.nbh or update.zip cannot be found, that means you didn't copy the files properly. Start over! Put your sdcard back into your computer, check the root of your sdcard for DREAIMG.nbh (that filename is case sensitive) and update.zip (case sensitive as well). Make sure that update.zip isn't named update.zip.zip (that often happens with Windows).
Once your phone has rebooted, you will have to log in again. Your should have your phone back.
I now recommend flashing Cyan's latest recovery image. Search XDA Developer's Forum for the latest. Download and install.
If you still want to try and flash a modified rom, hopefully you have learned from the experience and will be more careful. My suggestion is to the following items, in the following order. Search XDA for the proper thread.
-- DOWNLOAD ANY ADDITIONAL FILES YOU WILL NEED (rom, SPL?, radio)
Now is a good time to re-format & re-partition your sdcard.
In most instances, you will want 3 partitions in this order: Fat32/Ext3/Swap
If you don't have anything to partition your card, get a trial version of Paragon Partition Manager.
Once your card is partition, copy all of your needed files to the Fat32 partition.
Install Cyan's latest improved recovery image next.
Install the most up-to-date radio
If, and only if, the rom you want to install requires a different SPL, then install that.
Now install the modified rom of your choice.
It's a good idea to re-flash the latest radio once again.
Now create an emergency kit !
For future problems, take those two files you originally download from the top of this thread and put them on your sdcard right now ... in the root of your directory. ALWAYS KEEP THEM THERE ! Do NOT rename them (keep them DREAIMG.nbh and update.zip). That way, should your phone ever hit the crapper again, you are fully prepared to get your phone working again anywhere you are without the need for a computer.
NOTE: if you do keep DREAIMG.nbh and update.zip in the root of your sdcard, be careful not to overwrite the update.zip file with a modified rom update. When you want to install a modified rom, just copy the modified rom's .zip file to your sdcard (do not rename it, keep it named whatever the developer named it). If you are using Cyan's latest recovery image, you will be able to apply any update using any .zip file in the root of your sdcard. Update to a modified rom by choosing that rom's .zip file name.
Can we get a sticky please at the very top of the page since this is the #1 asked question everso we don't keep getting this new thread daily, I always kept dreaimg on my phone as a just in case emergency get out of jail free card. Can the op also edit his post to mention that you are not bricked if you can get into the recovery or bootloader just jammed up at the very top of his post
Great. Will these two files also work on EU G1 with RC7 original ROM?
If they flashed the newest SPL shouldn't they flash the Original SPL before the DREAIMG.nbh since I think it downgrades the radio or am I wrong?
That's pretty much the purpose of doing it the way I described. It's less risky to just flash the DREAIMG.nbh and let it take it back to factory condition. It does the SPL & the old radio. There is no need to do the original SPL first doing it this way. It's also the safest for anyone that's inexperienced.

agreed... can this be a sticky! it will help cut down on senseless new threads saying help or ummm i need advice.
this is a great write-up btw!
Can you post both links to the us rc29 and also eu version rc7 plus the cupcake upgrade since they are differant and flashing roms not meant for your locale could also cause problems

I will, and that's a very good point.
I'll do that when I get home in the morning.
Thanks for the suggestion.

Really? Wow all this time since RC33 I thought you had to flash the original SPL and DREAIMG.nbh to unroot lol

TNT keeps force closing on newest OTA update

Hey there hope this is the right place for this ... Just want to report something that has happened. I am currently unable to use the G tablet stock vanilla TnT... any clue as to why this would happen? I dont really use it anyway however should this be resolved? and would it affect the tablet in the long run if not addressed? I use Launcher pro and the tablet forces itself to that when "home" force closes. I would like to try the TnT lite however am not confident about it.
Do i need to root the device before i hold the power button and vol +? to flash the new rom ( it bugs me that this is all i have to do to put in a custom rom. it seems to easy, unless it is that easy)
Will i lose all the files, PDF's, and documents that i have on it once i flash the new rom ?
As you can see im a noob to Android. Thanks for advice and guidance in advanced and patients.
Follow the instructions in the alternate gtab firmware post. It worked great for me. I would suggest installing cwm so you can back up your existing firmware.
My update would force close during download on the stock firmware. I finally got it to work by minimizing the pop up that displayed the progress. For some reason the screen would crash the download.
Your files should be there but you will lose all user settings and installed apps when you do the factory reset.
This is a common issue with stock, and TnT Lite. The user data seems to be very unstable once you upgrade to different firmware.
The "easiest" thing to do is just wipe the user data. However, if there is certain data you need to keep, I would recommend the excellent Titanium Backup. The only caveat is that the device has to be rooted, to use it.

And Z4root does this easily. Just install and click "root".

Tntlite is that easy I was surprised. Too since rooting my HTC hero a year and a half ago was so much more hands on
Hey guys.... first off thanks for the advice it worked great it was easy to do... flashed TnT lite and was excited.... i attempted to pull an app from freewareloversDOTcom and was stuck in downloading status for some time even with a good wifi signal... This is where all hell broke loose ....the file i wanted never downloaded.... then the pic gallery forced closed then the launcher forced closed and had to shut down now now its in bootloop....I attempted to power and vol + but nothing happened in fact got a triangle !.... what is needed now.....
LOL at the entire situation this was my fear..... please if someone with extreme patients can list or point to a noob friendly thread on what i need to do
i have a microSD card can that be used read somewhere that i may need that.....
I thank you guys VERY VERY MUCH appreciate this

I had a similar problem twice today (installed TnT Lite 2.02 and ran into boot loops). Here's how I recovered. Results may vary, so use at your own risk:
1. Download the vanilla restore from http://forum.tegratab.com/viewtopic.php?f=6&t=16 (this is just to get the recovery\console file unless you want to manually create it).
2. Download the updated stock TnT from http://forum.xda-developers.com/showpost.php?p=9362168&postcount=35
3. Extract the "recovery" folder from gtab_full_vanilla_system_2010_11_09.zip downloaded in step 1.
4. In the recovery folder there is a file called "command" with no extension. Open this file with a text editor (eg. notepad) and edit the line so "SDCARD" says "SDCARD2" instead. Save it and ensure you do not add any extension. It should look like this:
--update_package=SDCARD2:/update.zip
5. Rename the "update-smb_a1002-2967-user.zip" from step 2 to "update.zip".
6. Copy the entire recovery folder with the edited "command" file from step 4 and the "update.zip" from step 5 to the root of your MicroSD card. It's important that the contents on the root of your MicroSD ends up with:
/update.zip
/recovery/command
7. Put the MicroSD in your gTablet.
8. Power on while holding the Volume Up button until you see a message regarding recovery.
9. You should see a graphic showing package box with a progress bar after a short time.
10. Wait until it completes and the unit will restart.
11. If all goes well, you should be back to stock TnT with the last OTA update.
If you are wondering why I just didn't use the gtab_full_vanilla_system_2010_11_09.zip downloaded in step 1, it's because it didn't help me. I initially used the same general method above with the gtab_full_vanilla_system_2010_11_09.zip downloaded in step 1, but my gTablet still continued to boot loop. After a fair amount of panicking and looking over all of the threads here, I found that gtab_full_vanilla_system_2010_11_09.zip added ClockWork Recovery so I was able to use this to copy over the update-smb_a1002-2967-user.zip to my internal SD, install it, and get my gTablet working again. When the problem happened the second time, I used the method above and it worked for me.
Hope this helps. Good luck.

After a fair amount of panicking and looking over all of the threads here, I found that gtab_full_vanilla_system_2010_11_09.zip added ClockWork Recovery so I was able to use this to copy over the update-smb_a1002-2967-user.zip to my internal SD, install it, and get my gTablet working again. When the problem happened the second time, I used the method above and it worked for me.
Hope this helps. Good luck.

You mind if I steal these directions? It's more detailed than the one I wrote up on my TnT Lite post. I'd like to post it there (specifically the command file, as some people have issues understanding the "SDCARD2" change).
And thanks for posting your experiences to help the other users here!

Please do if they look to be correct. Hopefully we'll see confirmation that these instructions work.
I appreciate all your work on the gTablet!

I had no luck trying to re-flash to 2.0X once I got in the boot loop - I couldn't get past it no matter what until I went back to stock. Once I was back at stock I could re-flash to 2.0X from the internal SD. I'm still trying to figure out what's getting me in the boot loop - everything seems to work great for a while.
Good luck!

have you flashed back to TnT lite back yet and how long does it last? Damn i am so tempted to go back im thinking it has something to do with what we attempted to load on the tablet ... i dont know just looking for a reason to Flash ....can this constant recovery flash do any damage to the tablet? I would like to try other Roms but dont want to mess my tablet up..
BTW i got this EUL when it rebooted especially sections 4.1 and 4.2 wtf!!! sorry about that but that is how i felt
Thanks again guys!!!!

If I remember correctly, the stock firmware with the OTA update will prompt you to accept a license and prompt to set the time, etc....
I just flashed the TnT 2.02 again. So far it seems OK, however it did the first 2 times I did it as well. I followed all of the instructions at "forum.androidcentral.com/showthread.php?p=442691#post442691" except I substituted using roeboot's TnT. Once I did it I had everything working (flash, market, etc...). Both times the boot loop happened when I tried to install or uninstall something, and both times were after a few hours of use. I tried a third time and almost instantly got into a boot loop, but I think I got ahead of myself in that try and did some things out of order. The good thing is that I was able to recover each time.
Out of curiosity, did your tablet come with a gray or green cloth to clean the screen? The reason I ask is that I thought I had seen somewhere that this might be an indication of a difference in gTablets.
The EULA shows up with a new stock firmware - and yeah 4.1 / 4.2 kinda bugged me too. I never selected "I Agree" - fark that.
As for the boot loops, it seems that we still can't pin it down - maybe it's just random, I don't know.
Hi,
I was stuck after bootlooping using Cyanmod, then flashing NVflash still didnt fix the issue, this fix did it for me. Thanks for getting me back up & running. I will give another shot at using cyanmod now that I have all the files needed to get me back.
BTW< I have a green cloth. What does that mean?
Thanks,
Rich

My tab came with a grey cloth... funny thing though I got mine on the second wave of shipments to sears... I NEVER had any issues with the time i just set it and it kept the time... I remembered that when these first came out that was a problem... i thought mine was diff because i never had any issues with time reseting itself... anyway Thanks again dude for your help hope i could play this forward to someone more noobier than me
Roebeet looking forward to your TnT lites...

I now have clockwork recovery installed... How do i copy the update.zip from external microsd to internal microsd... mounting sd-ext gives an error..
E:Can't mount /dev/block/mmcblk0p2
(No such file or directory)
Error mounting SDEXT:!
Frustration levels are high with this device!!
Thanks!
a "me too" reboot problem
I was able to install TNT Lite 2.0, then 2.11. I got Clockwork Recovery installed as well.
The market would start, but if I did a search for obvious things like "Kindle", the market would give an error that it didn't exist in the market. Thinking it was the error situation described here:
http://forum.xda-developers.com/showthread.php?t=845175
I applied those instructions, and rebooted.
Upon reboot, it ended up in a continual reboot loop.
Trying to do the start with volume+power, it brings up Clockwork Recovery, and when told to wipe data/factory reset, it stays in the reboot loop. When told to apply sdcard's update.zip, it looks only at the one on the internal sdcard, which is for CWR, and goes back into the loop.
At that point I setup a microSD with the information from this post:
http://forum.xda-developers.com/showpost.php?p=9439414&postcount=7
including changing the line from sdcard to sdcard2. Again it doesn't recognize that the internal sdcard2 is plugged in, and attempts to mount it with CWR (mount /sd-ext) yields the error:
E:Can't mount /dev/block/mmcblk0p2
(No such file or directory)
Error mounting SDEXT:!
So, unfortunately I'm at an impasse, like the previous poster. I just bought the tablet a couple of days ago, so I'm far from expert at tweaking it into working.
Any suggestions on what to do, are greatly appreciated.
PS - Bought the gtablet from Office Depot, and received a green cloth.
Boot into clockwork recovery and go to advanced and format SD, use the 2gb and 512mb I believe, then flash TNT or another rom. That fixed my boot loop.

Help with clockwork mod

First let me say thanks to all of you, I purchased my wife what was out of the box a useless machine. Then before I had an sd card out of desperation I used the tnt lite and flashed off onboard storage. all went fine.
Today I see there has been a few updates so I installed a microsd (16gb ) and attempted to do it correctly using the CW mod install guide. I mounted the card and used Es FE to extract the cwmod to root /sdcard folder then I powered down and did the volume +/power. I seen the prompts it looked like it went through. then i booted back into os and used esfe to delete them out of root booted down and it shows the prompts then a yellow exclamation and just goes back into OS no matter what I have tried. I tried several times.
I dont want to mod the unit anymore without the recommended recovery methods could someone guide me a bit why I cant get cwmod to load?
thanks
bump for attention
if you are using the internal sdcard.....SDCARD:
/sdcard/update.zip
/sdcard/recovery/command
"command" must have this line in it
--update_package=SDCARD:/update.zip
OR external sdcard.......SDCARD2
/sdcard2/update.zip
/sdcard2/recovery/command
"command" must have this line in it
--update_package=SDCARD2:/update.zip
CHECK THE COMMAND FILE. If you are booting with Power/Vol+ and its not going to the clockwork menu then clockwork is not installed. Installing any Viewsonic updates will erase cwm recovery
This'll make it do the recovery

I had the same scenario and it was due to the editor I was uing to make the recover/command file. Just delete what is in the recover/command folder, and unzip the file in the following link, and copy the file in the command folder to the SD. It WILL work with the next effort of install with the vol+ and power button function (sys recovery?) I got it to work, thanks to Robeet's Explanation....
The File is what I extracted from the original plain vanilla file that Robeet had referenced to on this forum. I only took the recovery/command part of the package.
Here is the link:

[Q] Sidekick 4G Woes

Argh! Pulling my hair out over this one. I've been flashing custom ROMs and rooting my phones for years now, since my old HTC G1. Even had KitKat running on my HTC Desire 4G!
... but this Sidekick is proving another matter. I've been through forum after forum, all saying the same things on how to root/flash this thing, but I haven't managed to get anything to work! So, here's step-by-step of what I just did and the result I get every single time, no matter the initial method:
1: Fired up ODIN3.
2: Wiped the user data and cache from the stock recovery (Android System Recovery (3e)).
3: Connect USB cable, reboot phone into download mode (using the battery-pull method).
4: Successfully flash to stock ROM, reboot.
5: Sign in with Google, enable WiFi.
6: Run SuperOneClick, reboot.
7: Grab ES File Explorer from the Market, after it updates.
8: Attempt to replace "recovery" in /system/bin with custom
... and here's where things break. Doesn't matter what version of SuperOneClick I use (and I've tried from 1.9.1 through 2.2.3), nor does it matter what exploit I select. What happens? Well... aside from everything on-screen claiming to be okay, and everything claiming it's working, once the rooting is "successful", I reboot like it says, see that SuperUser is in the applications, it shows me an su binary version...
... but anything that tries to run super-user (ES File Explorer included) that gets added to the super-user list simply does not work. I can't over-write the recovery, can't delete or muddle with anything that requires elevated privileges, and the ROM Manager for sure won't work because I can't get CWR installed.
I love my phones with keyboards. I really do. I'd love to keep this thing, but the stock firmware is driving me up a wall (especially that stupid media scanner). So if anyone has any ideas to throw at me, care to offer some? Haven't a clue at this point what I'm doing wrong.
Hey buddy!
I feel your pain, this is one of the last nicely built hardware keyboard phones, first time rooting it is a bit strange
See post #27 (or so) here
http://forum.xda-developers.com/showthread.php?t=2221030
I ran through the manual steps there and have links for needed files
If you get stuck let me know, I'll be around

Awesome! I'll give this a go once I'm all done with today's activities and see if it works.
Well, apparently I have root access for the moment, but it is denying my replacing of /system/bin/recovery - in adb shell, it states "Filesystem is read-only", so I re-mounted /system -rw and no dice. Going to attempt to try again in a moment, after a reboot.
Okay, so since there's a problem with all of this, I'm going to try that second ROM (KD2 I think it was) - but as I recall, it was on a very slow server. Plus I have a load of things to do tomorrow, so it probably won't be until tomorrow evening sometime when I'll be able to flash it. Once I've used Odin to re-flash, I'll get back to you.
Well, I had to dissect "t839-Sidekick4G-UVKG2-One-Click.jar" and remove the xml file from within it, but I acquired the necessary package to upgrade to KG2 from KD1 through Odin3. Took a while to figure out just how to deal with it, and I was successful in flashing... and I even replaced the recovery file after rooting it again!
... however, now it just sits there at the "T Mobile Sidekick 4G" start-up screen when I attempt to boot into recovery, so now I'm preparing to re-flash it again to recover the stock recovery. So... still more on this, later.
EDIT: Also, I named the tar file "KG2OdinHeimdall.tar", since I basically ripped it right off the "HeimdallPackage.tar" file from the Heimdall one-click thing. Turns out, it apparently works just fine if you remove the .xml file from the original tar.
Finally!
I ended up having to use my own method to get the KG2 update installed because the one-click program kept crashing on me when selecting "Show all devices", and I opted to use AntTek Explorer (all you have to do is go into the program's options and it'll attempt to acquire admin privileges, if the device is rooted) to copy the recovery file to /system/bin - but your post worked for everything else, once I got past not being able to copy the recovery file.
I opted for the CM6 package and it's quite fast! Thank you loads, demkantor!
Nice! I'm glad all worked out well for you!
If you get a chance try out the one gingerbread ROM, its cool to see it running but there are still driver issues so keyboard is borked, really makes it pointless to have on this phone...
But there are a few nice froyo ROMs ready to be played with, someday development will hopefully pick up again
Until then, happy flashing!
