G1 stuck at boot screen , nuthing working !!!!

---

friends i bought a g1 off the ebay recently. the seller said that its a g1 but after purchase i realize its a t mobile android dev phone 1. here are the details.

drea*** PVT 32b
hboot 0.95.3000
radio1 .22.12 .29

i doubt it was already rooted, it had android 1.5 os. today i was trying to flash it with laslo 5.2... i was following this guide http://forum.xda-developers.com/show....php?t=1098899 step by step .
but after i completed Step 1. Get to 1.5 stock and flash recovery!
' no 2 step correctly ,i wiped the data & applied the update after that during the reboot my g1 got stuck after showing the T-Mobile G1 logo followed by Android logo & then dark screen.
after that i am not being able to fastboot (camera+power) ,recovery (home+power) or anything else. tried removing the battery & SD card but its still the same, when i plug the USB cable it shows red LED .. there's nothing else. can anyone please tell me how can i fix this ? its been only 2 days since i bought it. any kind of help will be appreciated . thank you

If holding power + back, power + home, or power + camera only gets you the g1 screen then either your hardware buttons are bad or you have a brick. Only jtag will fix this, too bad because those dev phones are kinda rare

thanks for your reply bro...its hard to find a JTAG in Kolkata(india)... btw can you tell why dev phones are like this ? i mean are they very hard to be used with custom roms ?... i bought this phone from ebay just 2 days ago...

They're actualy easier to flash roms because they are prerooted. If your in india I remember seeing a thread somewhere in the g1 section recently mentioning a place that does jtag, don't know how close it is to you but if you find the thread it might be

Dev phones are special phones that are - like in the title - for developers. The special thing about these are that they are pre-rooted and are sim-free. So If you want to simlock free your device, just root and flash this over your phone, it will sim-free itself.
Also what's awesome about them, that they have such an awesome battery cover!
Also,

yes . i've already red that thread ... but its in Mumbai...n i m in kolkata..thats a long distance , btw i've recently checked that my phone can be switched to blue led mode, hope the JTAG is only option.. thanks for your concern guys...

you're welcome and that's why we are here! ;P

since i've been trying to flash this G1 from yesterday , I think you need to hold on to the home+power button for quite some time, i hold it till it shows up, takes some time thou

and try camera+power without sd card and see aswell

got it fixed for 1.5k....

WHAT!?!?!?!?!? that isn't worth it at all! They are refurbished for $120
