Hi,
I am reading through the forum and I am trying to clear a cople of things about upgrading and downgrading. What I don't understand is if I upgrade my G4 Xda Neo to some WM5 or WM6 G4 suitable version and the IPL/SPL is updated, will I be able to restore the original german ROM? I read somewhere that if you upgrade the bootloader and you try to downgrade you can brick your device. Since the original rom has IPL/SPL 2.15.xxx and the available ROMs are with 2.20.xxx it will be a problem.
Any kind of explanation is appreciated!

I searched in the forum, always read that SPL cannot be downgrade on G4, but is it possible to do it on G3?
Thanks.
I also want to know.
But no one will answer newbie's question.
Better ask in other forum.
If your device is CID unlocked you can. Search this great! forum my friend.

what I understand from the wiki is that this process only downgrade on the OS not SPL...
Not a problem
It does not matter if PDAMobiz ROM does downgrade or not the SPL. Once you will load mobiz ROM and then unlock your device, the next time you will be able to install whatever G3 ROM you want. You won't see anymore the RUU's telling you can not downgrade. Startup screen will inspect your device and will only find v1.2, a fake info that enables everything.
Hi guys, I am a new on ths forum and with te prophet. After using a hima for 3 years, I bought a prophet today. Since I was at wm2005 aku 3.5 with my hima, I cannot use my pim.vol any more with my current rom version, which is
Rom version 2.9.7.24 WWE
Rom date 2/9/2006
Radio 02.07.20
Protocol 413.1.03
Extrom 2.9.7.106
This is all new for me and I am hoping that someone could post me or PM me some advice on newer roms and how to upgrade. I also found a version with G3 or G4. What is the difference and what do I need to use.
This device works different, but it look very nice.
Can I re-use some of my old (hima) applications on this machine?
Thanks very much in advance. I hope to have as much pleasure on this forum as I had on the hima forum!
1. you can get some of the old apps working on wm5 devices, but not all of them.
2. check your device for G3-G4 issue here: http://wiki.xda-developers.com/index.php?pagename=prophet_g3g4_how
3. good thing if you have time to read this: http://wiki.xda-developers.com/index.php?pagename=HTC_Prophet
it will answer most of your questions on how to upgrade your ROM. read it three or four times: i'm not kidding - you may ruin your device if you miss something.
If I can hijack this thread for a second... is there any way to backup whatever ROM we have on a CID locked device? cause it seems kinda pointless to have to CID unlock the device (which involves FLASHING a completely new rom, overwriting the old), to open the backup feature at which point is useless since we've lost the original rom.

why not? just download your original ROM from this site or official site of qtek, jamin or whatever your device is.
afaik you CID unlock the device to be able to flash different ROMs (for example, to flash jamin with qtek ROM) and to be able to return back to your original ROM.
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!

hey guys,
after using hard_SPL-G4.exe
i made my SPL to 2.21.olip
what i have to do next? can i install a wm6 now perhaps Jaguar?
or what i have to do now? when i try BlackDiamond 3.1 Touch.rar i get error 300 invalid update tool and other wm6 dont work too...
plz help...
i have a MDA VARIO FROM T-online
If you read and understood the HardSPL thread in the G4 forum, you shouldn't be asking this. That thread is clear (IMO) how HardSPL works.
But put simply, yes, if you have HardSPL installed, then you can flash a custom rom like Jaguar or somesuch on your G4 just like the G3 users do. But you need to understand that you may have to switch the RUU that is used (again, that is discussed in the HardSPL thread in the G4 forum).
Please read and understand the HardSPL thread though before you wind up bricking your device.
u need to find the ruu mun file its laying around in the g4 forum im using a g4 myself so i have dealt with the process involved so if any questions just pm me or ask away in the g4 forum

Based on the SPL version, that's a G4. Any ROM will be fine as long as it is marked as G4 safe, i.e. it contains no SPL code. Read carefully the ROM author's instructions and make sure it is compatible with G4 devices. Most recent ROMS are G4 safe, but some older releases may be for G3 devices only.
Before flashing, make sure you read the general instructions for flashing ROMs on G4 devices. Failure to follow them could brick your device!
About which ROM: that's a matter of taste. Read up on them, browse features and screenshots, check the user comments, and choose the one you like best. I'm using the TNT ROM by itsright and I'm happy with it. I have a G4 Qtek 9100 too.

Very true !
I'll just add here that always remember a G4 device can never be CID unlocked like a G3 device,but it can be upgraded to wm6 by applying methods 'HardSPL' or 'SoftSPL',read about them in the G4 forum posted as 'Stickies'
