Downgrade from JB to ICS wo root - RAZR i Q&A, Help & Troubleshooting

Hey there,
I got a ne RAZRI (the old one was replace on warranty) unfortunately the new one already has JB on it. I dont want to open the bootloader for doing the rooting, but as far as I understood I cant downgrade without root / opened bootloader from JB to ICS. Has anybody found maybe a working solution for that in the meantime?? What I have heared is that they exchanged the boot loader, so you cant flash the old bootloader with RSLite, right?? What If we put the new bootloader (from the JB RSLite fastboot files) in the old ICS RSLite fastboot package and try to flash. Could this work?? Or does it make no sense?
Cheers,
Thorsten

You cannot downgrade your bootloader. I think you're stuck until someone finds a way to root the new HBOOT.
I just want to go back to the stock android 2.1 , then update it to 2.2 ofiicially without rooting
The 'custom ROM' you flashed is actually official FroYo. There would be no difference even if you downgraded and got official FroYo. (Its not possible yet as stated above anyway, but, just letting you know)

am i able to install any rom with flash tool? that guide is v good btw i was following it but not to actually install a rom as i cant see root yet...
oh...
first you need to do some research before you go playing, always keep a stock FTF to hand just in case anything goes wrong
ROOT
Install CWM
Stock rom which allows you to do a bit more modding
A must for the XZ: Pure sound
CWM Will allow you to install Rom's and mods. but at the moment you will have to say on Andriod 4.1.2 becuase you will have a locked bootloader and if you unlock that (You have to enter a certain code in a program ) you really need to know what you are doing becuase or at least something
P.S. Here to help but you do need to read, not just jump in at the deep end and hope for the best
DIDNT WANT TO POST AGAIN: Is your bootloader locked of unlocked (Have you entered something like fastboot.exe -i 0x0fce oem unlock 0xKEY)

ReInstall origional ROM ?

Hi Guys,
Thanks for all previous help in un-rooting my Razr I in the past using you the below method by HSD-Pilot:
Relock your Bootloader
You'll need an complete JB (4.1.2) Fastboot File of your Region for doing that!
Copy the content of the [XT890] Re-lock Bootloader.zip into the extracted Fastboot File Folder
However, since I have done this I have had a few issues with the phone (very slow at time, sometimes freezes) So I have re-rooted but I can no longer install any custom ROM's as they constantly bootloop. I was wandering whether I could reinstall my initial software using RDS-Lite. I am currently on (91.2.29001.XT890.Retail.en.GB). Can I go to the stock Orange GB version or can I reinstall the same Retail.en.GB version using RSD-Lite?
If I install using RSD-Lite will i need to unlock the bootloader or unlock bootloader and install a custom ROM?
I hope that RSD-Lite might fix any issues I have with my phone.
Many Thanks
D
Hi,
I will be having the same issue after having tested some custom ROMs in the future.
I believe after what I have read that it is the easiest way to unlock the bootloader to install any kind of ROMs, although no guarantee on that.

Slow device - stock factory reflash

hello guys ...
using htc first for a long time now ... unlocked stock jb rooted at&t device outside US ..
since past few days it has become slow due to many apps n stuff i did ....
wanted to reflash the device back to the way it was ...
so my question is ...
1.) where can i get the stock images to reflash ?
2.) i know i will loose the root after flash .. but will the device be locked again ?? and needs to be unlocked again ?
3.) what is the procedure to reflash the device ? (not familiar with htc devices as i was a sony user previously which uses flashtool for all purposes) is there any such tool for htc ?
thanks in advance......

Rooted with towelroot.What next?

Dear all,
I have rooted my device which is running 4.3 (c5502) (build number: . 101) with towelroot. Now i need to install any custom ROM. I came to know that it requires to install recovery first before flash any ROM. I stuck there..Can you please guide me. I didn't unlock my bootloader yet but I had my TA backup with me.Thanks in advance guys.
whatever u need to know is already there. just search for it. if u expect to be spoonfed then you really shouldn't mess with your phone
The thing is, do we really need to unlock boot loader to flash custom roms, or can it be closed just with root and recovery?
No one tryed it till now I think.
Greetings.

Yes for flashing custom Roms the bootloader must be unlocked and a recovery must be installed however if you want to flash a stock based Rom unlocked boot loader is not needed. Just Root and Recovery needed for flashing the stock based Roms. Correct me if i am wrong.
