UMI IRON bricked

Haagentis

Hello, I need help :

I've tried to reboot my phone in recovery mode by holding the button Volume+ and power.

I've been presented a simple menu with 3 choices :

• Recovery Mode
• Fastboot Mode
• Normal Boot
  

I've selected "recovery mode", expecting to be presented a menu which would allow me to factory wipe my defective SD card.

Unfortunately, after selecting this option, my phone quickly powered off. And now it won't boot.

I can still use the volume+ and power combination to boot to this three choices menu, but none of them works : I get the "Umi Simple But Diligently" screen, then the phone goes black after a few seconds.

It's impossible to reboot.

Is there a solution ?

Hello,

Try to reflash your phone with SP Flash Tool. You can find the downloads and a guide HERE
Currently only the 1.5 version is available, but after a successful flashing you can upgrade to 1.6 by Rootjoy.

Thank you ! I will try that ! And sorry for my late answer, I was busy all day long. I'll tell you how it went !

\n\nSPFlashTool says that the scatter file I found in the 1.5 unzipped file (the compressed ROM) is invalid, and it won't load it (error 8417). What should I do ?

Haagentis

EXCELLENT NEWS !!! I used the 1.4 version and its scatter file, and my phone boots again ! I'll upload it with Rootjoy ! Thank you for your diligence, Bencebacsi.

Aaaaand now my simcard isn't recognized.

Use this recent version of SPFT: SP_Flash_Tool_v5.1532.rar. That will accept the scatter file of the 1.5 version. I checked it earlier. Choose the 'Firmware Upgrade' option. After you're done, check the IMEI numbers by dialing *#06# if you still don't get a working network.

Hey Bencebacsi !

My phone boots again, but, Oh my... My IMEI is invalid. I've searched on the internet how to fix that, and I'll try using MTKDroid. Hopefuly, I won't have to pry open the phone, as my IMEI is mentionned on a label in the phone's original box.

I'll keep you posted ! I also hope my misfortune and workarounds can help people in similar situations.

\n\nOk, so far, I've been able to use the "MTK Engineering Mode" app to input my IMEIs without using a PC (apparently, MTK Droid Tools doesn't work on 64bits devices yet), but my SIM card still isn't recognized.

I hope it's only my sim card that isn't functionnal (but it worked before my bricking problem!), as I had to cut it as a nano sim card... I also hope I didn't damage the sim slot while extracting the card, using the tiny metal pin... if that's the case, I think I'm done...

Also, I don't know if it could indicate anything, but Rootjoy doesn't recognize my phone eventhough USB debugging is activated. That's strange.

I have ordered a new sim card, and I'll keep checking if I haven't done any mistake while trying to restore my IMEI... But when I type *#06# in the phone I don't have any "invalid" IMEI message, and the 2 IMEIs are displayed ! I'm a bit lost... Does it have something to do with "NVRAM" ?

... I'm realizing I haven't tried what you said. I'll reflash with your method, maybe it'll get my phone to recognize my SIM card.

EDIT : No. I used the version of SPFT in your link and the 1.5 rom's scatter file downloaded with rootjoy, and SPFT still says that the scatter file is invalid.

I'm going crazy.
