[Motorola Droid and Milestone Q&A, Help & Troublesh] roofghost:
Fellow androiders,

I believe I am in a really rare brick situation that no matter how I try, it still does not show any turn around.

[Introduction]

I bought a Korean version Milestone(Moto Qrty, as they put], and I took it to China. Because the original phone did not support sending Chinese text message, plus, too much telco provided apps are making the phone sluggish, I decided to follow my friend advice, to switch to widely available open-sourced Froyo (I wanted the CM).

[Problem]

I thought that the flashing process would not be too difficult and I could handle it by myself. But, it turns out that I have become a victim of an overly simplified version of flashing guide. I don't know what exactly have done wrong, after successfully rooted the phone, I vaguely remember that I have used CM ROM for Droid, instead of CM ROM for Milestone.

And that made my phone a brick. My phone will turn on, but will restart again and again after M logo(So-called M boot loop).

[Background information of the Phone and my PC environment]

Phone Model: A853

Original Bootloader version: A0.20

Original Android System: Froyo

RSD lite version: 5.3.1. (later switched to 4.6 due to the suspicion of RSD bug)

Operating System: Windows 7 64 bit, English

[What I have tried so far]

I have tried to follow many tips on the internet. Tips from Korean websites, from Chinese websites, and from English websites. Basically, these tips will let you flash back to the original ROM by using RSD lite.

But, no matter what I try, it will not fix the boot loop problem.

I've tried to

1) Bring the phone to the original status [did not work.]

- flash the bootloader into A0.20 (the original bootloader) with RSD lite;

(bl_a020_umts_sholesumts_skt_consumer_replacer.sbf)

- flash with original Froyo sbf (following the advice from Korean websites, flashed Clair first, and then flashed Froyo) with RSD lite.

(A853_2.1(Eclair).SBF / A853_2.2.1(Proyo).SBF)

* According to what Koreans say, it would make your phone into the original status, will even remove signs of root.

2) Used many combination of following bootloader and ROMs

- flash the bootloader into 90.78ch

(BL_9078_umts_sholes_GC_HS_Consumer_replacer.sbf)

- flash the bootloader into 90.78

(BL_9078_umts_sholes_HS_Consumer_replacer.sbf)

- GOT221 ROM

(GOT_RTEU_2_2_1FULL.sbf)

- And some other un-name-able ROMs

SGC_U2_03.04.0_USASHLSGCB1B2B5008.0R_PDS06A_HWp2a_1FF.sbf

3) Used many different OpenRecovery Variations

OpenRecovery v1.46

OpenRecovery 3.3

OpenRecovery GOT mod v2.1

4) Restore Nandroid backup which I made right before I made my phone brick.

5) Cleaned data/cache/dalvic as I do every flash, and tried boot without SIM card and SDCard.

[Some discoveries and successes]

- With 90.78ch + GOT2.2.1, it will show "Android" screen, but it will reboot as soon as the phone OS interface show up.

- According to my friend, when he flashed back to the original bootloader A0.20 + original froyo Rom, it showed TelCo Symbol "T" once (which is the booting screen right after M).

[Final Comment]

What I really want to know is that is it the time I give up on it? or is there any value of pursuing other knowledge on bring this phone back?

I really need this phone, and it will take some times to save money to buy another smartphone, I would really really appreciate if you can help me bring this phone back to normal.

Thank you.
