Build no. CRC1

When I try to flash back to RC7, the gray screen comes up with "Loading" then "not allow", then it goes to the multi-colored screen.
here is spec:
DREA110 PVT 32B
HBOOT-0.96.0000
CPLD-4
RADIO-2.22.19.26I

I have tried naming the file DREAIMG.nbh , DreaIMG.nbh, DREAIMG.NBH, DreaIMG.NBH. It always says "not allow". I have tried downloading the file from two different sources. Still no joy. Could there be something wrong with my G1? Does anyone have a download location of a confirmed working image file?

and last thing: i was wondering if i downgrade my g1 will it simlock it and i have to buy a new unlock code?

you need goldcard way .. same as me ( dutch )

Unable to root German G1 running Donut
Hi guys,

I am also running into trouble while trying to root my German G1 running Donut, after formatting my SD Card using FAT 32 (many different formatting actions tried - from phone, from windows explorer menu, from command line prompt).

Then I obtained a goldcard.img using the reversed cid (replaced first two characters from reversed version with 00) and wrote the image to my sdcard (connected through a card reader) using HxD.

The card was then inserted into the phone, the latter being then powered-on while pressing the camera button. At this point I do get the "rainbow" screen, it then shows a grey screen which first says "loading...", then "checking..." and then "0028002 not allow".

My sdcard is a 2 GB SanDisk, might there be a problem with this brand not being supported?

Is there anybody out there experiencing this issue with the G1 Donut using the goldcard method? I thought that the goldcard was supposed to fix these issues.

Or even better, *is* there anybody out there who has managed to root a German (or Continental European) G1 running stock Donut?

Any Ideas??? i am 100% sure that the format of my SD is FAT32 but not sure about the file i download. i tried many.
Thanks in advance!And also tried the goldcard version.

Hi,
I wanted to root my Dutch G1 and I followed all thes steps. When
I put DREAIMG.NBH on my SD Card and restart my phone with camera+power buttons I get this;

"Loading", then "Not allow", and then it goes to the Rainbow-screen

DREA110 PVT 32B
HBOOT-0.95.0000
CPLD-4
RADIO-2.22.19.26I

I saw a lot of people having this problem, does someone know an solution for it?


My phone;

T-mobile G1
Firmware version 1.6
Baseband Version 62.50S.20.17U_2.22.19.26I
Kernel Version 2.6.29-00479-g3c7df37
[email protected] #19
Build Number DRC92

Bytheway, this is what I got using an 4GB SanDisk Micro SD. I saw somewhere else that I had to use an 2GB SD, but with that one I couldn't even put DREAIMG.NBH on it, because I ad to format it again

I have the same problem as CoolSebas.
Also a Dutch T-Mobile phone.
I bought it new and unused last week, the store had one left for sale.
With the 2 Gb SD card that was inserted in the phone I have the same problem as CoolSebas: right after pasting the part from the Goldcard.img Windows prompts me to format the card, so I couldnt put dreaimg.nbh on the card.
Besides the already slotted 2 Gb card there was also an 8 Gb extra SD card, and with that card I also get the "not allow" message after booting.
Exactly the same kernel, android and build version as his G1.

Any suggestions would be appreciated.

I solved the "not allow" issue.

It comes down to: rename DREAIMG.NBH to DREAIMG.nbh

Then it worked.... sigh.. that cost me 6 hours of trying and rebooting.
Hope it's to some use for you guys.

For the Dutch guys here, I did exactly what it says here: http://gathering.tweakers.net/forum/...21624#33821624

Question
Heel erg bedankt allemaal! Het is me eindelijk gelukt om m'n telefoon te rooten.

Maar ik heb nog één klein vraagje, ik zit namelijk vast in Android 1.0. HOE update ik mijn telefoon naar Android 2.2 (dit moet volgens mij kunnen)?

Ik heb erg veel geprobeert, maar ik wordt telkens doorverwezen naar een andere site, om telkens weer iets anders te installeren, updaten, etc. Wie kan mij helpen?

Als ik de instructies van dit topic volg, en ik WIPE m'n telefoon, dan start hij opnieuw op, net zoals bij een gewone recovery (opnieuw opstarten, Google-account invoeren, etc.). Daarna zet ik de telefoon uit, en start hem op in recovery-mode. Ik druk op Alt+S en TOT dan lijkt alles goed te gaan, ik krijg namelijk dit;

Installing from sdcard...
Finding update package...
Opening update package...
Verifying update package...
Installing update...
E:Can't find update script
Installation aborted.

Press Home+Back to reboot


Ligt dit aan de update die ik wil installeren (dat is trouwens de CyanogenMod-6 for Dream & Magic - V6.0.0) of moet ik eerst nog iets anders doen?

-------------------------------------------------------------------------------------------------------------------------------------------------

[Update]
Oké, ik zit dus niet meer vast in Android 1.0, maar in 1.6... En volgens mij heb ik toch wel Root access. Nu is alleen de vraag: Hoe moet ik van 1.6 naar 2.2? Ik blijf verder zoeken naar een oplossing, maar als iemand iets heeft, dan hoor ik het graag...

-------------------------------------------------------------------------------------------------------------------------------------------------

[Update]
OMG!! Het is me dan eindelijk gelukt! Ik heb Froyo om m'n G1 geïnstalleerd! Het duurde even, maar na een paar tutorials op youtube en via google staat de CyanogenMod 6 op m'n telefoon. Ik moest gewoon de update FLASHEN via recovery, en niet als update installeren (jullie zullen me wel dom vinden dat ik dat niet wist). Ik ben super blij, en ik wil iedereen hier erg bedanken!
