Gen1 to Gen2 TPT Upgrade

This will convert your Gen1 phone to Gen2 & boot into ClockworkMod for you to install your rom. You will lose your data. Make any backups you want first. Gen1 nandroid backups wont restore on a Gen2 phone. Always check MD5s, one way to do it is to download AFV (Android File Verifier) from the Android Market, search for AFV.

It is for European Gen1 ZTE Blades, Orange San Franciscos, Sapo A5s & Base Luteas sold with Android 2.1 Eclair only. None of the downloads on this page will work if your phone was sold with or operator upgraded to Android 2.2 Froyo. In that case, you already have the upgraded radio firmware. This is a safer alternative to the operator 2.2 upgrades which keeps some of the good features of Gen1 (like fastboot mode, tpt mode & extra storage space), but upgrades everything necessary to run Gen2 Android 2.2 Froyo & Android 2.3 Gingerbread roms.

Custom rom version (should work well with most custom roms, more room for your apps & data)

Instructions
Copy a Gen2 rom zip file to your sd card ready to install. Check the md5sum of that against the source (you can use AFV for this).

Unzip this Gen2 TPT zip file to your sd card, it should create an image directory.

Check the nandroid.md5 file in the image directory on your sd card using AFV on your phone (long press on nandroid.md5 file, then Verify Nandroid Backup)

Power off, wait a few seconds, then power on with menu & vol+ held.

It should take a few seconds to flash the new Gen2 firmware (you should see some green text), then it should reboot into ClockworkMod recovery, use that to wipe data & then install your Gen2 rom.

Once installed, remove the image directory from your sd card, to prevent accidentally reinstalling. Once you have installed this just vol+ & power on will send you back into tpt mode if there is an image directory, even if you needed menu & vol+ before.

It is reversible using any Gen1 full TPT (links below), but this will only work on phones that have been upgraded using this method, not phones bought with Gen2 or upgraded with the windows software.


Going back to Gen1

If you upgraded to Gen2 using the above TPT, then going back to Gen1 is easy & safe (if not, sorry, out of luck here). You can install any Gen1 TPT to go back to Gen1, but make sure that it contains a Gen1 amss.mbn & amsshd.mbn use the same method described above, with the files listed below.

Here is Gen1 with stock partitions & ClockworkMod 3.0.14 (16.4mb) -

Safety
Charge your phone first, make sure it's well charged before doing any TPT, but remove it from the charger before you TPT.
Check the MD5 of any files, they're there for a reason. AFV from the android market will help you to check the files on your phone, there is a nandroid.md5 file to check.
There is a nandroid.md5 file in the image directory, check that when it's on your phone, using AFV from Android Market.
There is a small risk of breaking your phone with any TPT flash.
No guarantees, no warranty, no support.
Remove the image directory from your sd card after install, to prevent accidental wipe & re-installs in future.

Hey wbaw I had previously updated my blade from Gen1 to Gen2 (using 140 mb system tpt). For CM7 I wanted 160 mb system partition, so I used this v9 tpt image.
But now my phone is not getting past big green Android Logo. I cannot even enter recovery mode
What could be the solution? thanks

PS: I checked md5 before flashing

Did you check the md5 on the phone, like it says in the instructions? You need to check the md5 of all the files after they're extracted to the phone's sd card in case there was any error copying. That's why I say to download & use AFV (other apps are available, or 'md5sum -c /sdcard/image/nandroid.md5' from a command line does the same.)

Did you seen some green text while it was flashing?

Do you own a microsd card reader? (if not, buy one, Poundland & other cheap shops sell them).

Assuming that it did actually flash & you're not just stuck in fastboot mode. The only thing you can do to fix it is try another TPT, or the same one again.

Use a microsd card reader to put the tpt files on your phone's sd card, safely remove it, then put the card back in the reader & check the md5sum in the image directory on your sd card. Then put it back in your phone & try again.

If you didn't get any green text, then it didn't flash & you're in fastboot mode, you just need to pull the battery out. Some sd cards seem incompatible & wont perform a tpt flash.

Finally, 140mb system is (just) enough for CM 7.1 & the latest gapps, there should be about 2mb free. That might change in the future & some other roms are bigger, that's why I made the recent versions 160mb. There is always a (small) risk of breaking your phone each time you do a TPT flash, even if you do everything right, so it should only be done if necessary.

So if I proceed like you said with the CM7.1 Version I'm done and have rooted my ZTE and installed CM 7.1 in just one step??

One more question,if I want to use the TPT the way it's mentioned @ http://wiki.cyanogenmod.com/wiki/ZTE_Blade_%28Gen1%29:_Radio_Conversion_and_Recovery
does my phone need to be rooted because at the end says "will automatically boot into the ClockworkMod Recovery"??

Correct. Your phone doesn't need to be rooted first. If you have a 'gen1' blade or san francisco (sold with android 2.1 eclair) then you can use this tpt to install CM 7.1 & clockworkmod in one easy step.

You just need to extract the cm 7.1 tpt zip file to your phones sd card, check it extracted properly (on your phone, using afv or another md5 checker), turn your phone off, then hold menu & vol+ buttons when you power it on. You'll see some green text on the screen while it flashes, then the first boot will take a while & in about 10 minutes it'll start into cyanogenmod.

You will lose all data from your phone's internal memory (not the sd card), so if you care about saving any app data then you should root it to install titanium backup first.

Affirmative to both your questions. I guess I'll go search for another microSD card then.

edit: it worked with a different card.
maybe it only works with sdhc cards?

it also works with normal 2gb sd cards, like those which are supplied with the phone. it's just a few sd cards that don't seem to work with tpt mode, i don't know if there is any pattern to it. what brand was the microsd card that wouldn't tpt?

What if I have different md5 checksum thing on the cm7.tpt thing? I checked the "nandroid.md5" thing. And which of the checks should I even do?

Click to expand...

If you get a different md5 then you should delete what you've downloaded & try downloading it again, from a different mirror if you can. Then check it again.

DO NOT FLASH ANY OF THESE FILES IF THE MD5 DOESN'T MATCH - IT COULD BREAK YOUR PHONE PERMANENTLY

If you're using afv to check the md5s on your phone (recommended) then you should long press on the /image/nandroid.md5 file then 'Verify Nandroid Backup' or 'md5sum -c Type check' (same thing), alternatively if you're happy using adb/command line then you can type the following ...


Other apps do the same thing, there is nothing special about AFV, it's just the first app that I found to do it.
