downgrade wm6 to wm5!

Hy...I have a G4 model, Qtek s200, and i was wondering if I will install a wm6 version, and if I will not be satisfied, can i downgrade to wm5 back?

I think so... Even if have CID locked, but i'm not quite sure. Anyone correct me if i'm wrong please!!

Hi:
I have one HK 818pro G4 model and have tried wm6.0 and downgrade to wm5.0,
it's no problem.
palo

Yeah, it's no problem to downgrade! I played yesterday with some different WM5 ROM's (Orange UK, Qtek and O2) on my G4 XDA Neo and had no prpoblems at all time!

up
so, i don't have to follow some specials steps...the normal way, no?

Yes, just follow the normal steps to do it. By the way, which WM6 rom you will try?! Looks like the smart1 clear it's good.

up
first of all: i want to install a wm6 version, but i don't know which one ... I have G4 model..can you give me an advice? also, i want without bugs if i can (that's the first reason that i didn't try yet)... i mean, to connect on wap, to work fine the new wm6...if you know what is the "perfect" version to install on my device, i am waiting your opinion

There is no "perfect" WM6 yet but the SMART1 WM6 Rom (clear) it's quite good... in this thread they talk about it and is litle bugs: http://forum.xda-developers.com/showthread.php?t=295225

I tried Smart1's WM6 ROM and successfully downgraded it to WM5 (I-mate) portuguese ROM by just using the normal procedure.
The problem is it doesn't work properly with Windows Vista. Don't try to upgrade to WM6 on Vista as it wont work properly!
Cheerz!

up
so your advice is to wait another version more reliable of wm6? i supouse that wm6 = win vista isn't it?

Just a question about downgrading - I read somewhere in the forum that it is important NOT to downgrade to a lower IPL or SPL because it will brick the device. is it so?

Hi,
Would like to know too how to downgrade without risking to brick my device...
I have a G4 that I upgraded to WM6 recently (SMART clear rom).
I liked WM6 but I have to remove it because it is only compatible with ActiveCrap 4.5, which doesn't support outlook 2000 anymore (version used at my office) .
my IPL/SPL : 2.10.0001
I would like to downgrade to last AKU 3.3 (couldn't backup my wm5 rom since my prophet is CID locked). Can I downgrade to AKU 3.3 safely?
Thank you very much

Yes, you can do it safely! My Neo is a G4 too and I switched often between smart1 clear WM6, the official O2 update, ASerg's 3.3.12 US nad the Qtek 2.20 with no problems!

I know T-Mobile Shadow has just new ROM update with any bug removed (include can use Suretype ABC mode not XT9 mode)
Anyone can share me:

- Unlock CID or change region to upgrade my phone
Many thanks
p/s: I think I bought a refubished phone cause error" Incorrect IMEI" when check online at HTC website

latest t-mobile shadow upgrade

Hi Erofish,
Many thanks for link download, now i have Chinese ROM for Dopod C750, so if u can help me about change regional to ugrade T-Mobile Shadow ROM.
I hear from any members when upgrade, phone will be locked and only acept with T-Mobile Simcard
Best regard,

I don't think you need to. Someone else who had the unlocked htc juno was able to update to the official t-mobile shadow rom. T-Mobile just has the branding and Neo interface on the rom, nothing else.

Thanks for reply, ND4SPD!
In my case, now running on Chinese ROM and WiFi driver is not loaded.
Your solution to change or upgrade for my phone

Unlocked Treo750 need HSPL before ROM?

Hi. Im new and wanna say THANK YOU to all of you for the opportunity. I have an unlocked Treo750 AT&T branded (actually with Tmobile) Windows Mobile 6 Professional CE OS 5.2.1620. I am interested to do the navenedrob 6.5 upgrade. Can I install the ROM directly or I have to do HSPL first?

U need HSPL. Follow navenedrob's tutorial to do it here. I would highly recommend navenedrob's ROM too. I use it on my treo. Don't use his new one yet. It still has some bugs, but his timebomb fix one is excellent.

Thanks for the info. I will try right now!!!

Hello everybody,
thanks for all details on XDA!
I have got a question.
Is it possible to downgrade the IPL to version 0.20, SPL to version 0.24.000 and the firmware (radio?) to version 1.54.01.00 when I patch to WM 6.5?
I ask this, because I still have a guarantee for my Treo 750v.
Thanks a lot!

KAISERv2Unlock UED file

Hello,
Im trying to unlock my HTC kaiser(Wm 6.1) using the KAISERv2Unlock. At the end of prozess I get the file 355757015478544.ued and the print out on the console "Please upload the file now to get your unlock code" but where?
Thanks

That's some commercial program right?
Are you trying to CID/HardSPL it or SIM unlock it? It is all free, just check our top sticked thread with howto.

Hi,
Oups yes is a commercial product sorry. I want to unlock my phone but i have wm 6.1 why can i downgrade to 6.0.

You must downgrade to 6.1 because the patched radio you'll flash isn't 6.1 compatible.

You only need to downgrade for jockyw2001's SIM unlocker. Olipro's SIM/CID unlocker/changer worked fine on 6.5 for me.
Dave
EDIT: Looks like you beat me to it

Unlocking is free for the Kaiser.
Please read the stickies, downgrading is possible, just use Hard SPL or use Olipro's unlocker for 6.1 ROMs.
