Red Screen With White Nokia Letters - Nokia Lumia 920

hello. i attempted to flash my lumia 920 rm-820 to rm-821 and during the eu rom flash my device gave an installation failure. now my device is stuck on a red screen with white nokia letters. i can restart it by holding down power plus volume down but after restart it shows the nokia boot sign then quickly goes back to the red screen. in nokia care suite it says my device is in flash mode. i have tried to flash rogers rm-820, eu fr rm-821, at&t rm-820, eu dev rm-821. all of them fail at the flashing rom part. i get a "message to device failed" message in NCS. does anyone have an idea on how to get past this red screen? if not, can anyone recommend a good jtag service?

Well it's because your installed rom (in your C:\ProgramData\Nokia\Packages\Products folder) is damaged or now available for your phone. Well i got that Red Screen thing yesterday and changed the rom. It went all well. Try and tell us what happened pls.

[Q] Possible to change Lumia 800 firmware to another region?

Hi guyz,
I have a Nokia Lumia 800 with me of UK region and I dont mean just software wise. The actual phone was shipped from UK and the product code is 059J3G0
Now I reside in India and due to this region differences many of the features dont work especially USSD which is proving problematic since its difficult to even check my balance.
So is it possible to change my firmware to Indian version?
Thanks.
Possible very much, infact I have updated to the latest UK firmware, but will flash it back to the original White Lumia 800 firmware

Yes you can
1) goto seidea[dot]com and start off by downloading the Nokia Care Suit and Data Package Manager.
2) After installation of both also install the WinUSB driver from C:\Program Files\Nokia\Nokia Care Suite\Drivers or C:\Program Files(x86)\Nokia\Nokia Care Suite\Drivers
3) Connect your phone with the Nokia Support Tool for Store open, this programme will have a launcher in the main Nokia Care Suite, and should have detected your phone, disconnect cable, this might restart your phone, this is normal.
4) Next fire up the Data Package Manager and search for RM-801 in product type, this will return a bunch of different variations of the firmware. In the cell below Name type India and download any of the firmwares you want, possibly to match the colour of your phone as well.
5) After download fire up the Nokia Support Tool for Store, change it to offline mode at bottom right, or simply disconnect from the Internet,from the file menu, select Open Product and select product RM-801
6) From the bottom left pane, select Programming and then Recovery and select the new firmware you just finished downloading.
7) Flashing should take 5-7 minutes and leave the phone un-attended. Voila
Again I take no responsibility for any dammage to your phone, and you may download and flash any firmware from the entire list under RM-801 should not be a problem.
Additionally you may also want to take a backup from WP7 Easy Backup, google it or search the forums for it.
regards
Prateek
mohib.sheth,
no problems at all, i´m from Brazil and i updated to test Tango one from Mexico and another from UK, both worked like a charm.
U can follow this thread if u have any issues, like dead phone, errors or different Product Code
RM-819 Firmware on RM-801 thanks to thesmartguyy
or simple follow the original one Tango:
New update !! Rm801_059q201_1750.0805.8773.12220_002 thanks to surya467
Thank you so much lohiaprateek and xpc21 for the steps.
Another query is If I do flash to India firmware, will I get update from regular Zune or I will need to keep flashing to the latest firmware manually?
Zune should prompt the update ideally..

USSD is not supported (fully) in Windows Phone so as far as that goes changing to an Indian FW will not make any difference.

[FLASH] How to use NCS to change from RM-820 to RM-821 and vice versa

Band Issue was fixed with the latest update....
****************************
I investigate more about it and the problem is only in VODAFONE DE hardware so far, so I can say is safe to do ---> Do not change from 821 to 820 your bands will get screw, always will show the LTE bands for the 820, even if you flash back to 821 pre-portico and portico. Now my phone is not working properly, every time I go in network search the phone reboot...any help from anyone will be appreciated?
****************************
I am going to explain in an easy way, assuming you have some basic knowledge to flash any other produces like 820 to another 820 or from 821 to another 821:
Case 1: Nokia Lumia 820 or Roger Product RM-820 to International Version RM-821
a. Do not connect the phone.
b. Download the FW that you like.
c. Create the folder in ….\Products\RM-820
d. Copy the files for the RM-821 FW that you previous download in that folder.
e. Open NCS, open product, select RM-820 and it will highlight the FW that you put in that folder.
f. Press start, the NCS will validate the FW and explain to press volume down + power and retry key to proceed to flash.
g. At this time with the phone off, press volume down + power and as soon the phone vibrate, connect to usb and press retry.
h. That is it. Your phone from RM-820 will be recognizing as RM-821.
Note: The original product code will always remain.
Case 2: Nokia Lumia International Version RM-821 to 820 or Roger Product RM-820 or any product converted before as RM-821
a. Do not connect the phone.
b. Download the FW that you like.
c. Create the folder in ….\Products\RM-821
d. Copy the files for the RM-820 FW that you previous download in that folder.
e. Open NCS, open product, select RM-821 and it will highlight the FW that you put in that folder.
f. Press start, the NCS will validate the FW and explain to press volume down + power and retry key to proceed to flash.
g. At this time with the phone off, press volume down + power and as soon the phone vibrate, connect to usb and press retry.
h. That is it. Your phone from RM-821 will be recognizing as RM-821.
Note: The original product code will always remain.
I hope that clarify how to do it and help others to enjoying flashing. A thanks click will be appreciated and I am not responsible for any damage caused by this procedure to any of you.

************************************************************************************************************************************************************************************************
For some reason there is no way to change a RM-820 ATT and RM-822 to RM-821. Everything else RM-820 can go RM-821 and vice versa.
Thanks for this tutorial...
I'd like to ask you something maybe you (or someone) know the answer for...
I have an unlocked Rogers 920 which I am not using on Rogers, but on an AWS carrier. It works fine mostly, but if I flash/reflash, I cannot restore any backup, since I cannot get data working until I set up the network access point app that someone found hiding in the store a while ago. But I cannot download it until I get connected to wi-fi, and I cannot connect until the phone is fully set up, at which point, I can no longer restore a backup... (thanks to MS for this, I guess)...
At this point, I have a few apps installed, some were even downloaded on special days that were free, so if I flash the standard way, I will lose them and will have to install them again...
Do you know (or can you guess) if once the DEV ROM is installed the phone does allow to connect to data without having to install the access point add-on from the Store? That way, I would be able to restore my backup...
Any input will be greatly appreciated.

Hello,
Thanks for posting the tutorial. Do you have any information on how this may affect future OTA updates once NCS is shut down?
Not really known 100% at this point. When I flashed my ATT 920 to Rogers pre-portico rom, it let me do the OTA upgrade to the rogers portico rom. Not sure if this will still work if you change an RM-820 into an RM-821 but it seems like it will.
What exactly do I gain from installing an international version RM-821 onto my Rogers RM-820? To my understanding it would unbrand it (boot screen, pre-installed applications) and get tethering to work. Can anyone else confirm that? Anything else?
Also, you mention "Download the FW that you like.", where can we find firmware and how will we know that its compatible?

What exactly do I gain? Just fun installing other FW for diferents countries.
Can anyone else confirm that? You did mention.
Download the FW that you like? NaviFirm+ 1.7
how will we know that its compatible? 820 / 821 / 822 all are compatible.

The major thing is that if you have lost your AWS band, flashing the RM-821 euro dev rom will enable it again. It will also get rid of the boot logo and all preinstalled apps.

I test in every ways and I can flash from 821 to 820 to any FW without no problem and vice verse, you must be doing something wrong. Try to install the latest NCS 2013, this what i used.
for the ppl asking about tethering on ATT Lumia,
I have my ATT lumia 920 with stock ATT rom and I have tethering enabled on it, you need to download the "access point" app from the market and then tethering will be enabled on your device.
This is the link for the app, click on it from your cell phone:

Which version of NCS are you using? Can you give a link? I can't flash my AT&T to Rogers or Euro Dev
I believe the only way to get from ATT to Rogers and for that matter Euro DEV is to do ATT (pre or post protico) to Rogers pre-portico then update via OTA then Euro Dev. The way back to ATT is kinda unknown because... well why the hell would you want to go back to a restricted bloat filled turd like the ATT ROM. Anyways this was all covered and gone over in the other thread about the Euro Dev ROM and a little in the Lost Rogers AWS thread....
I want to flash rm-820 for ATT to firmware rm-821 but I have an error
0xFA001304: Platform ID check fails. Reason(s): The FFU file is not meant for this product. The platform ID of image does not match with platform ID of the device.

I just flashed ROGERS pre-portico on my AT&T 920 and installed Access Point. I'm able to tether .
Now I'm trying to get the unbranded Euro dev ROM installed, but if I can't get that, the Rogers ROM is good enough. No restrictions, gets updates when AT&T ROM does, and lets me tether. Might be best to stay on it, actually!
Edit: Can't seem to get LTE working on the Rogers ROM... Odd since they use the same LTE bands, don't they?

You can download the latest version in this thread over here:
http://forum.xda-developers.com/showthread.php?t=1605144
Uninstall the old version and install this, them update to latest version from the NCS.
So far to go from any 821 to 820 ATT “fail”, form any 821 to 820 Roger “work ok”, this happen with portico.
I am download the ATT pre-portico to try again If I get this successfully I will modify the post to explain how to go from 821 to 820 ATT and from 820 Roger to 820 ATT.
Stay tune…!
I updated Rogers to Portico and using the Access Point app and switching to 2G max then back to LTE max, my ATT 920 now is running Rogers ROM and lets me access LTE, but it's giving me the stupid call 611 message when I try to tether now. ****.
Flashed Euro Dev Portico ROM. No go on tethering with that, either. Going back to rogers portico now. I was able to enable tethering a few times with Rogers, but it started giving me that dumb message consistently. Damn AT&T.

Try to manually set up the APN, or if you can reset your phone using the Euro Dev ROM with your SIM in the phone to allow ADC to run. What is happening is when you switch to LTE it pulls ATT's settings (which include the tethering block) from pre-defined APN's stored on the phone, not from the SIM itself. Although under the Euro Dev ROM you probably won't get LTE because I believe the bands are set differently than what is needed for ATT but you should still be able to tether via 3G(H) or 4G(H+)

[Q] AT&T Lumia 920 flashing problems

Hello Folks,
I have done a research on this forum and I was unable to find an answer for my problem. I have a friend who owns an AT&T Lumia 920 who tried to flash it with a Rogers rom. He successfully was able to flash it into the rom RM-820_VAR_AMERICA_CA_ROGERSWIR_SL_BLACK-059Q6W4_1232.5951.1249.0001 which isn't available on NaviFirm Plus anymore. Now, the phone doesn't function and when you try to turn it on, it will not turn on. The only way to get the phone powering on is when you plug it into the wall charger. It will show the Rogers logo for a second and then it will be stuck at the Nokia logo with a red background. I tried to flash the phone with the latest AT&T roms that are available on NaviFirm but everytime I try to do so I get this message:
0xFA001304: Platform ID check fails. Reason(s): The FFU file is not meant for this product. The platform ID of image does not match with platform ID of the device.
Is there anyway I can force a rom into the phone? Or is there an AT&T rom that is not available on NaviFirm anymore but will still work on the phone? It's really frustrating to have to download a lot of GBs just to find out that the roms do not work. I would greatly appreciate your assistance.

[Q] Unable to flash my Lumia 920

well im trying to flash my Lumia 920 from ATT "059N5T3" with a ROGERS "059R6P3" firmware "rm-820" the problem is actually getting the phone to detect the reboot.
I follow the steps shown in the video youtube.com/watch?v=O4tU4oRkyAs but the problem is that the NOKIA logo shows first before the ATT logo in my phone. and for some reason i cant get the phone to get into recovery mode, i've tried more than 12 times unsuccessfully. is there another way to make it detect it ?
The normal boot sequence is the nokia logo and the AT&T logo and then Windows and running.

Hi,
You have to use old pre-portico (RM820_1232.2109.1242.1002) firmware in order to do this.

[Q] Returning to AT&T ROM

Several months ago, I followed the process many on these forums did of developer unlocking my Nokia Lumia 920 via the Canada Rogers ROM. For a while it was great, but I would like to now return it to the AT&T ROM, as all the updates I believe are caught up. Some of my apps, including some Nokia ones, seem to not play well with this developer ROM, and my WiFi is hit or miss at home now, possibly due to this ROM. Is there any way to un-developer unlock my phone?

What is you Hardware Product Code?
The Hardware Product Code is generally inscribed physically on/in the drawer of the SIM card or on/in one MicroSD card), 059.......
I wasn't able to find any numbers on my SIM tray, and my phone is a Nokia Lumia 920, so I do not have a Micro SD slot. Is there any other way to find this number? I was also unable to find it in the "About Phone" section under Settings.

Extra+info:
Value of Manufacturer Name?
RM-820_nam_canada_246
That is the ROM I put on there about a year ago in an attempt to update early. It was originally an AT&T Lumia 920.

I was wrong, the value is that of the current rom, not the Hardware Product Code. But it does not matter.
Normally your Hardware Product Code is ATT U.S.
So just re-flash the present Hardware Product Code, with Nokia Software Recovery Tool ou Nokia Care Suite (Software Updater Module !).
Nokia Software Recovery Tool does not recognize my phone. If I connect my phone after opening the program, it says it was unable to connect with my phone. If I select that my phone is unresponsive, it asks that I reset the phone via VolDown and Power, and try again. This also does not work. Is the Other option, Nokia Care Suite, my only option? It seems intimidating, but I can try it.

For Nokia Care Suite, you have two options:
- Either you do not fully follow the tutorial and you go directly to the Software Updater module.
- Either you fully follow the tutorial (in having taken the right Product Type and the right Product Code).
There isn't a way to do it, I've tried flashing pre and post portico ATT roms, but once you flash a Rogers RM-820_nam_canada_246 you're stuck with it.
I have not however, after moving to 8.1 tried any of the new roms, or know if they are available, but might be worth a try.
OK assuming Etaduck is right, and I have no way of returning to AT&T's ROM, what am I missing out on?
